Thousands of incidents occur each year in which oil or chemicals are released into the environment as a result of accidents or natural disasters
Spills into our coastal waters and inland waterways
the environment and the economies on which we rely
causing substantial disruption of marine transportation with potential widespread economic impacts
When spills occur, NOAA Scientific Support Coordinators (SSCs) coordinate scientific information and provide critical information to the FOSC. A multidisciplinary team of scientists, including oceanographers, modelers, biologists, chemists, and geologists support the SSCs during spill events as well as for drills, exercises, and contingency planning. SSCs are strategically located around the country
effectively providing local services to a range of users in public and private sectors
and provides expertise on issues such as dispersant use
ERD has responded to virtually every major marine spill in the U.S
ERD's expertise is frequently sought internationally
While oil and chemical spills are the major focus
ERD also provides support for incidents such as downed aircraft
The Emergency Response Division typically responds to 150 incidents annually. News, photos, and other information about current and historical spill incidents is available at OR&R's IncidentNews site
field-oriented job aids to assist preparedness for response communities
NOAA provides standard techniques for observing oil
and evaluating and selecting cleanup technologies that have been widely accepted by response agencies
Some of ERD's more widely distributed products:
Each year, ERD provides training to approximately 1,000 individuals in industry and government on the scientific aspects of oil and chemical spill response
The goal of ERD training is to transfer scientific expertise and experience to the broadest possible audience
Successful training promotes more efficient planning and spill response

Levy explained that he tends to think of his shows like films. “The runway isn’t spiritually fulfilling enough,” he said, noting that the film aspect only came in after long weeks in the studio putting together a collection that could easily have included a beloved character or two.
Influences included the Viennese Succession, art brut, primitive art, and a love of jewelry—the designer wears lots—from the ornate silver belt with a pin closure on look 1 to a doctor bag in box leather set with a Patek Philippe watch.

The cage, a metaphor for the alienation that drives the individual in the bleak postmodern landscape
is a theme that has entered the imagination of Henri Alexander for some time now
A symbol that soon became an obsession in the mind of the Atlanta-born designer
who chose to transform the Parisian headquarters of Sotheby’s, the world's most renowned auction house, into the set of The Experiment
by installing a series of cages - a simplified version of the “stainless steel (synthesizer) prison unit” launched by the brand last March - to present the SS25 collection of Enfants Riches Déprimés
a borderline play of contrasts gave voice to the most explicit paradox
generating a sort of perverse short circuit: rich kids criticizing capitalism through clothes that only equally rich kids can afford
In a room with violet-toned marble walls and cream-colored carpet
Alexander said about the collection: «Everything for me is very personal
I choose everything day by day as I work on the collection
with fictitious guards shaving the prisoners' heads
the collection alternated structured tailoring suits
and loden coats with lamé sweaters and crotch-hugging shorts
accompanied by latex gloves and leg warmers
becomes the voice of this macabre exploration of forced assimilation
and silent oppression that underlies modern existence
Trench coats made by layering belts with jingling silver straps gave way to the fetishism of jumpsuits
a play of domination culminating in an homage to Steven Shainberg’s Secretary
could only use her lips to perform her office duties
To enrich the narrative or perhaps to confuse us further in a dense game of references, young baronets with deliberately emaciated faces strutted in their frayed pastel-toned culottes
a light blue dress paired with pointed slippers evoking Sofia Coppola’s punk court of Marie Antoinette
we found a cream silk dress with trompe d’oeil lingerie details
paired with the brand’s now-characteristic towering platforms
before yielding the stage to Renata Litvinova
a well-known fashion figure and close friend of the Gvasalia brothers and Lotta Volkova
When asked if there was a more literal and autobiographical meaning behind the extensive use of cages in constructing the narrative around the collection
Alexander laughed: «I think my brand is really based on repression
but I don’t necessarily do things for some hidden meaning
I have a feeling that drives me to do something
I’m sure there could be some sort of psychoanalytic exploration»
One thing is certain: the designer has sublimated a past made of Swiss boarding schools and rehab centers into an imagery for “elite punks”
that over the years has been enriched with DIY biker jackets costing $7,000
sweaters with decadent illustrations of Lou Reed or characters from Hugo’s Les Misérables
torn tees emblazoned with the Le Rosey crest
both the brand and Alexander himself have acquired a new awareness
pushing the design towards an increasingly elevated tailoring mastery and building a clear narrative around the themes that
ERD’s work questions the self-imposed slavery we maintain while pursuing autonomy and success
creating a collection that is a meta-reflection on the false idols that drive our frantic search for self-determination

There are a lot of optics on the market these days, and what’s out there can be overwhelming. It’s easy to get into the rut of just sticking with the big three or four brands you’re familiar with, but you’d be missing out if you do. There are some great optics from companies that you may not know yet and the ERD-1 from C&H Precision is probably one of them
I’d been seeing C&H optics pop up in my social media feed for a while now and decided to take a closer look. The optic I picked up for review is their ERD-1
enclosed optic designed for rifle and carbine use
the ERD-1 has a square window which gives you more viewing area
It uses a red 2 MOA dot surrounded by a 56 MOA circle
but also has a selectable multi-reticle if you want other options.The ERD-1 uses a single CR 2032 3V Lithium battery
you aren’t going to be swapping batteries in this one very often
There are 10 brightness settings including 2 night vision levels.
One of the things that intrigued me about the ERD-1 was that it appeared to be a very rugged build
CNC machined body and is both shockproof and waterproof
which is good for 1 meter submersion for up to 30 minutes.
It mounts to a Picatinny rail through the use of four bolts
Solid is an understatement when you have the ERD-1 locked on to your rail
I got the ERD-1 just in time to work with the MEAN Arms Bearing Delay Upper mounted on my SIG M400 lower
The MEAN is a slick 9mm set up designed to be a drop in 9mm conversion for your rifle caliber lower
although you are cranking down four screws instead of the usual two
the ERD-1 almost seems like a monolithic feature of the upper
It isn’t going anywhere once its secured to your rail
Not that you’ll have to do that often with the ERD’s battery life and shake awake feature anyway
I’m still old school I guess and don’t always trust the shake awake system
It seems to work quite well on the ERD-1 though
even after it had been sitting days between use
the sight was on by the time I put the gun to my shoulder
but the on works as soon as any movement is detected.
and it’s easy to see through the big 27.5 x 36mm window
The circle-dot reticle was easy to pick up
and the brightness setting range was more than enough to accommodate even bright summer sun on the range
The windage and elevation knobs are well marked
in 1 MOA per click adjustments. I’ve used the term easy a lot so far
It’s solid and well thought out and things performed as they should
I’m a fan of things that don’t need fidgeting with to do their job
If you want to try the other reticle options on the ERD-1
Just hold in on the “+” button and the reticle will blink then switch to the next setting
Let up on the button to confirm your choice
just a circle with no dot or the dot and circle reticle
Especially on the MEAN Bearing Delay Upper
so I also tried the ERD-1 out on my Aero Precision .308 SBR
Re-sighting in from the 9mm to the .308 was again quick and uneventful
I didn’t run thousands of rounds through the Aero
The ERD-1 was unaffected and held zero without issue
With its rugged mount I think it might find a permanent home on the .308
especially if I pair it up with a magnifier
Overall I used the ERD-1 throughout the summer and into early fall and probably have put 1,000 or so rounds of 9mm and .308 through two different platforms using it
It’s held zero without issue and has performed well in lighting conditions ranging from bright summer sun to dusk
Temperature ranges were from the high 90s to the mid 50s
just your typical Western Pennsylvania weather for this time of year
It rolled around in the back of the Jeep without a case on a few trips
and had a couple spills where it was knocked over in my shop and at the range
just normal use with the occasional bobble
but it’s withstood all of that just fine

Erdene Resource Development Corp. (ERD.CA) offers investors the best of both worlds: A near-term gold producer plus extraordinary exploration upside, explains Brien Lundin, executive editor of Gold Newsletter
Erdene has not only outlined the gold-rich BK deposit in Mongolia
but also multiple other gold and polymetallic discoveries and targets in the broader Khundii district that it controls in conjunction with 50% partner Mongolian Mining Co
What really excites the company’s geological team is that exploration has revealed the potential to unlock a new
large-scale gold district within the Central Asian Orogenic Belt
It hosts giant gold and gold-copper deposits such as Kumtor (14 million ounces gold)
That’s the remarkable exploration potential of Erdene’s assets
there’s gold production on the table
with the first gold pour at BK slated for mid-2025
open-pittable deposit is projected to generate uncommon profits
A recently updated feasibility study on BK demonstrates the strong economics of this deposit and what it will mean for Erdene’s market value
With 513,700 ounces of reserves and an average head grade of over 3 g/t gold (about three times the global average for an open pit mine)
BK has a projected after-tax net present value of $275 million and a rich after-tax internal rate of return of 49% at $2,200/oz
All-in sustaining costs are projected to be just $869/oz.
which implies truly extraordinary cash flows at today’s much higher gold prices
The best part: These remarkable economics are why Erdene and its local partner are rapidly advancing BK toward construction and cash flow
but they have truly only scratched the surface of this remarkable new district’s potential
The key here is that Erdene has been conducting a large exploration drilling program on nearby and outlying targets on its property licenses
and the results have been consistently returning high-grade hits
throughout the year as the mine rapidly progresses toward production
we have the best of both worlds with Erdene — a severely undervalued development story with the kicker of exceptional exploration upside in the near- and medium-terms

Enfants Riches Déprimés (ERD) showed their Printemps/Été 2025 collection at Sotheby’s Paris
and the silent oppression that defines the modern experience
The collection serves as a boldly placed vintage aesthetic critique of capitalism and the universal worship of wealth and youth
deconstructed designs accented with antique silver
comes a vintage patchwork facade of new designs and dresses unleashing characters endlessly for the audience's gaze
The runway transformed into a thought-provoking installation, with designer Henri Alexander employing the motif of the cage to symbolize the alienation felt in today’s postmodern landscape
Models were placed within a series of cages
echoing the “stainless steel (synthesizer) prison unit” introduced by the brand earlier this year
This setting created a powerful juxtaposition between excesses and oppression
with structured tailoring— the Napoleonic jackets and tailored vests—paired against lamé sweaters and daring skin-baring shorts
reflecting what I’m going through,” Alexander shared
emphasizing the iterative process of creation
The collection’s raw seams and self-binding details offered a unique visualization of constraint
the glossy materials highlighted the emptiness of excess
Leather played a central role in the collection also embodying the darker narrative of forced assimilation and rejection
Trench coats constructed from varied layered belts adorned with jingling silver chains showcased a striking blend of fetishism and elegance
With a nod to power dynamics and submission
The atmosphere was further charged by the appearance of young baronets in frayed pastel culottes and a light blue dress reminiscent of Sofia Coppola’s Marie Antoinette
blending historical references with contemporary critique
A cream silk dress featuring trompe l’oeil lingerie details
paired with ERD’s signature towering platforms
This added depth to the visual narrative ERD was trying to display
As well as one unexpected twist; a smaller cage on a model’s wrist housed a live rat
encapsulating the collection's provocative edge
The looks remain timeless and show a refreshing take on vintage allure; captivating

The C&H Precision ERD-1 is an enclosed optic
This means that the matter in charge of creating the reticle you see in the glass is protected from the elements and is less likely to be damaged or obstructed in those precious moments you may need it
We have witnessed a rise in popularity for these types of optics when it comes to carry guns and battle rifles equipped with red dot optics
it is a true red dot equipped with a multi-reticle system
The MSRP of the C&H ERD-1 Red Dot Sight is currently at $494.95 which is pretty competitive compared to other larger enclosed red dot sights that are not holographic
When you have something like this I am not sure why someone would lean into a holographic but hey
large windowed rifle optic that will be a perfect match for your gas rifle or PCC
It was built for those who want a larger window on a tough
It utilizes a picatinny rail mount for widespread compatibility
Available in red dot with 2 moa dot and 56 moa circle with a selectable multi-reticle.”
As I mentioned the first time I saw and held the ERD-1 was at Shot Show 2024 and I was totally star-struck
Everything about this thing was very appealing
The T&E sample I received is likely very much a first sample off of the line
The box is blank and there were no instructions included
I am guessing I was one of the first to step up to the review plate
Thank goodness they tracked one down for me because this optic was on my mind for months
It is on the heavier dense side so if you are going for a lightweight build it may not be for you but if it’s going on a battle rifle or SBR build it fits the bill because it feels like a tank
I really like the mounting setup and the battery access as well as the large button adjustments/placement
It is a very good-looking optic and a perfect profile for someone looking for that holographic sight look without the battery drawbacks and price tag
Mounting the ERD-1 was extremely easy
It has four screws securing it so with those tightened down to 15 to 20 inch pounds (not sure what the right spec is as I said my early sample did not have instructions) it was not going anywhere
It uses a side load battery so that was super easy to install but in a pinch
I can see unscrewing the locking screw being an issue
Good thing this lasts for around 5 years worth of battery and has an auto shutoff
With the dot up and running it yielded a crisp and clear reticle
Everyone I have shown it to remarked how crisp it was
It was just as nice as the one I saw at SHOT
Who knows maybe it’s the same one since this is a sample
Prepping for some range time I wanted to give the ERD-1 a great go of it with a new pistol and future SBR build
Needless to say it really suited the compact package and complimented the looks all day long
I paired it with my new AT3 Tactical lower
and a Silencer Central Backcountry for that added flair
I do need to pick up some backup sights for this build but I was in a rush
For my sake drop your favorite backup sights in the comments
Rolling into the range day I was vibrating with excitement
Fellow TFB writer and AllOutdoor editor Adam S was with me on my range trip and even he remarked how impressed he was with the clean lines of the optic and the crispness of the reticle
I set up a few targets at 25 yards and typically I wouldn’t bother sighting a review optic in to precisely besides getting it on paper mainly because you can still tell how something groups or if there is a change in point of impact
Does not really matter if there is a bullseye where the holes are
Since I wanted to have as much time with the ERD-1 I took the extra time and effort to get it hitting bullseyes
and loud enough to hear through my earplugs
Everything kept on target and there weren’t any noticeable shifts from the optic
The window was clear whether I shot out in the sun or under the low light of the range canopy
The brightness settings felt sort of lacking
Not in a sense they were not bright enough
rather I just noticed that some of the higher levels felt like there should have been a level in between each other
it felt like I was at setting 8 and then clicking up once the brightness would increase pretty noticeably as if it jumped to a figurative 10
It almost looks like an etched reticle on a prism optic
the dot itself developed a slight fuzz but very slight
Many other dots in this price range are far worse in my experience
In closing, I want to say thank you to C&H Precision for allowing TFB and myself the opportunity to try out their new ERD-1 Red Dot Sight
we would like to know what all of you guys and gals think
Do you believe that this new-fangled enclosed optic is worth spending your money on
Would you take this out to the range on the regular
Let us know all of your thoughts in the comments below

This looks like a decent first attempt? and I haven't seen anything similar from any other MFG, so this may have been one of their first actual designs (or something they had real design input into)
Aye, but you can be damn sure it ain't gonna come off or lose zero because the mount wasn't up to recoil.
$495 does appear to be the going rate, which is way too close in price to the made-in-not-China SIG Romeo 8H, and a good bit more than a Holosun AEMS.

This article is part of the Research TopicChronic rhinosinusitis in patients with NSAID-exacerbated respiratory diseasesView all 4 articles
Patients with non-steroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) often suffer from chronic rhinosinusitis (CRS) with nasal polyps
Although this disease is also seen in NSAID-tolerant patients
CRS in N-ERD often is more severe and more treatment resistant; local nasal therapy (nasal corticosteroids) and endoscopic sinus surgery are employed like in NSAID-tolerant patients
but with limited and/or short-lived effects
This mini-review gives an overview of the current additional treatment options for CRS in N-ERD
antileukotriene therapy and biologicals are discussed based on the current body of literature
Selecting the right treatment strategy depends on shared-decision making
local availability and cooperation between ENT-surgeons
Patients with CRS and N-ERD are at risk for uncontrolled sinonasal disease, requiring more surgeries and/or more intense medical therapy, often with unsatisfactory results (15)
This review aims to give an update of the current therapeutic options for the management of CRS in patients with N-ERD
In the past decades, CRS was divided between “with polyps” (CRSwNP) or “without polyps” (CRSsNP) based on the endoscopic appearance of polyps. However, with the newest update of the European Position Paper on Rhinosinusitis and Nasal Polyps 2020 (EPOS2020), a more diverse classification is proposed (1)
CRS is first classified as primary or secondary
based on the absence or presence of underlying pathology such as cystic fibrosis
Primary CRS is then divided between localized or diffuse disease
and endotyped roughly as either Type 2 or Non-type 2 disease
The CRS found in N-ERD patients thus classifies as primary diffuse Type 2 CRS
We will use this latter terminology in the rest of this review
although most literature is based on the former (simplified) diagnosis of CRS(wNP)
Following the management schemes of EPOS2020 the first line of treatment for primary diffuse CRS is appropriate medical therapy (AMT)
but not limited to local corticosteroids (either spray
Those achieving disease controls with AMT should be advised to continue their medication without the need for further investigation or therapy
when patients indicate a poor disease control with AMT
it is advised to perform additional investigations in order to differentiate the disease as a Type 2 or Non-type 2 primary diffuse CRS
patients with CRSwNP and N-ERD fulfill the criteria for Type 2 disease
Studies show that especially patients with N-ERD show a limited effect of AMT and/or FESS, resulting in higher oral corticosteroid use, more frequent surgery and a lower quality of life (15, 21). Qualitative analyses show that patients experience great frustration as they often find themselves trapped between their allergist suggesting more oral corticosteroids and their ENT-surgeon advocating yet another surgery (22)
many N-ERD patients have to deal with a chronic
yet uncontrolled disease state of their CRS
It is therefore pivotal that treating physicians acquaint themselves with the additional treatment options listed below
N-ERD patients are advised to avoid NSAIDs, selective COX-1 inhibitors, and alcohol consumption (21) as these might trigger a sudden increase in symptoms from the upper and lower airways
COX-2 inhibitors are generally well-tolerated
We are not aware of studies reporting on the success of such avoidance stratagems or how often patients are (unintentionally) exposed to these drugs or triggers
numbers were small and a large portion of participants had mild CRS based on baseline SNOT-22 scores
A different diet with high omega-3/low omega-6 fatty acids showed promising result in a small pilot trial with 10 adult patients suffering from primary diffuse Type 2 CRS and N-ERD (25)
Along with biomarkers indicating a change in cellular fatty acid composition
SNOT-22 scores decreased 15.1 points on average (95% CI: −24.3; −6.0) after a 2-weeks high omega-3/low omega-6 fatty acids diet
This unblinded setup might contain placebo effects and the findings remain to be confirmed in larger studies
Aspirin therapy after desensitization (ATAD) is based on a two-step treatment: first
patients are desensitized by exposure to increasing doses of oral aspirin; second
they continue using high doses of aspirin daily
Several studies have investigated this treatment option in primary diffuse Type 2 CRS in N-ERD patients
The finding that N-ERD patients experience a short period (24–72 h) of symptom alleviation after a challenge with aspirin, and that they are refractory to additional aspirin challenges (26), has led to the development of several desensitization protocols. A widely used protocol aims at oral aspirin 625 mg twice daily after a startup phase (27)
There have been several studies describing the effect of such protocols on CRS signs and symptoms
four of which are placebo-controlled trials
ATAD was shown to have a significant effect over placebo in the reduction of SNOT-22 scores or other symptoms scores
this did not reach the threshold for a clinically relevant difference
The lung functions scores (FEV-1) were significantly better with ATAD
The meta-analyses were based on relatively small pooled patient groups
ATAD is a relevant treatment option for primary diffuse Type 2 CRS in N-ERD patients
education and shared decision making are key for a successful application of this treatment
it seems logical to use antileukotriene drugs
in the treatment strategy of CRS in general
After reviewing the current evidence on antileukotrienes in CRS, the EPOS2020 steering committee concluded that the use of such drugs in CRS was not advised, as (limited) evidence shows no benefit over the use of nasal corticosteroid or when used in combination with nasal corticosteroids. Only in patients not tolerating nasal corticosteroids, one might consider antileukotrienes although there a no supporting studies (1)
the zileuton group used this drug for 77 days on average (range 6–300 days)
Although these two studies are small and from their setup give limited evidence
it seems that also for N-ERD patients specifically
antileukotrienes are not to be recommended as an additional treatment strategy for their CRS
It is important to recognize, however, that the European Academy for Allergy and Clininal Immunology (EAACI) position paper on the diagnosis and management of N-ERD does describe the use of antileukotrienes in N-ERD patients as add-on therapy for their asthma (21)
a N-ERD patient with both CRS and asthma might benefit from these drugs
but the indication should be derived from the lower airway disease status
With the advent of biological therapy, the management of primary diffuse Type 2 CRS has been tremendously revolutionized. Pivotal trials and the first real-life data show rapid disease control and improvement of the quality of life, often beyond the effect sizes that treatment strategies hitherto could offer (40–42)
these trials target patients with primary diffuse Type 2 CRS per se
either in the context of N-ERD or in NSAID-tolerant patients
No randomized-controlled trials with N-ERD patients only have been performed
Dupilumab is a monoclonal antibody directed against the alpha unit of the IL4/IL13 receptor. It was approved late 2019 as add-on therapy for CRSwNP. In a post-hoc analysis from a previously published phase 2a trial (45)
the N-ERD patients (n=19) and NSAID-tolerant patients (n = 41) were compared
Both groups showed significant improvements in disease control after 16 weeks of treatment
as assessed by imaging (Lund-Mackay score)
patient-reported outcome measures (SNOT-22 total score
and smell test score (University of Pennsylvania Smell Identification Test)
Eight N-ERD patients were in the dupilumab-treated group
Their nasal polyp scores were significantly reduced by a mean of 2.51
whereas the NSAID-tolerant patients had a non-significant reduction of 0.72
Mepolizumab is an antibody directed against IL-5. It is currently not registered for use in CRSwNP patients, but for asthma only. In a retrospective study including 17 N-ERD patients receiving mepolizumab for severe asthma, SNOT-22 scores were observed to decrease significantly and relevantly by 17.7 points (n = 11). Specific SNOT-22 questions on nasal congestion and smell/taste also showed an improvement with three or more doses of mepolizumab (46)
depending on the local situation/availability
In order to better understand and compare treatment effects
we would advise authors of future studies on primary diffuse Type 2 CRS to report effects in N-ERD patients separately
It remains to be elucidated whether the presence of N-ERD represents a clinically relevant subgroup when it comes to treatment outcomes
or that most patients with primary diffuse Type 2 CRS in the context of N-ERD respond largely similar to NSAID-tolerant patients
This mini-review describes the possible therapeutic options for primary diffuse Type 2 CRS in N-ERD patients
Apart from the customary appropriate medical therapy and surgery
ATAD and especially biologicals hold most promise for the future
The treatment options are summarized in Table 1
For most of the therapeutic options described
patient counseling and shared-decision making are key to success
all of these represent a long-term therapy
Treating physicians should be keen to inquire for patient preferences
clear communication with the patient is essential
with an important role for managing expectations
a patient-tailored approach includes treatment plans for the upper airway (as discussed here)
Most of these treatments are therefore best employed in close collaboration between allergists
Summary of treatment options for primary diffuse Type 2 CRS in N-ERD
the evidence for most treatment options relies on relatively small studies
studies targeting N-ERD patients specifically are needed
and studies including both NSAID-tolerant and intolerant patients should report on the subgroup of N-ERD subjects separately
Especially biologicals deserve attention in the coming years
not only with a focus on treatment outcomes
biologicals will prove not to be cost-effective in a broad group of primary diffuse Type 2 CRS patients
but only in the more severe cases; N-ERD patients typically fall in the latter group

To the members of Erie Roller Derby
it doesn't matter whether you're an expert skater or new to wheels
whether you're part of the LGBTQ+ community or not
they compete as the Erie Roller Derby All-Stars and the Bayfront Bombshells
But the participants in this community-based roller derby league do more than practice their sport
they promote inclusion of players and fans
roller derby has always been a place for people who are looking for a place to belong," said Allison McCartney
public relations manager for Erie Roller Derby
"ERD strives to cultivate a community that embodies the acceptance we as a league are committed to
we are focused on supporting and representing the queer community in Erie
including making our events and league a welcoming and safe place for all members of the LGBTQIA+ community."
McCartney said Erie Roller Derby was formerly known as Eerie Roller Girls
"We want everyone to know that no matter your race
you have a place on our team," said Sydney Alloway
She has been with ERD about two years and is a jammer/pivot
"If anyone needs a safe space or if they want a place to be themselves while staying active
then Erie Roller Derby is a great place to be," Alloway said
Skaters this year ranged from ages 18 to 48
Home rink: Erie area's Presque Isle Skating & Event Center has new owners and a new name
skating is only a fraction of what we help each other out with," she said
adding that the league "excels in compassion and thoughtfulness" and has a group chat that's a source of support in many ways
"One of our skaters is a mechanic," Damon said
"Even though car maintenance isn't a huge part of roller derby itself
that skater offered to host a seminar of sorts to share her skills with us
We're constantly looking out for one another
and that includes multiple aspects of our lives
What makes Erie Roller Derby different is that care for our fellow teammates transcends the boundaries of the rink and pours into our everyday lives."
McCartney estimated that 75% of Erie Roller Derby skaters identify as members of the LGBTQ+ community
The support between the skaters and the community is reciprocal
with ERD members taking part in Pride events and members of the LGBTQ+ community attending league games
"Our June bout is Pride-themed each year to help spread the message of acceptance that Pride represents," McCartney said
ERD members went to Pride on the Bay before their June 29 game
which a group from the NWPA Pride Alliance attended
Roller derby participants then skated in Erie's Pride Parade the next day
"Pride Month at Erie Roller Derby is truly a sight to behold," Damon said
"We don't just stop at raising a rainbow flag
I feel like communities as a whole have only tolerated me at best," Damon said
I've always felt as though that part of my identity has had to remain unattached to whatever sport or service I was providing
I was shocked to find that diversity was not just accepted
Damon said that's not just true for the LGBTQ+ community
"All types of people all the time are always being uplifted," she said
is a bench coach/blocker who lives in Wesleyville and grew up in a small town where she said she was the first Black person who played basketball
She said ERD members are "embracers of people" who never judge others
"Erie Roller Derby is more than just a group of people showing Pride and support to our community," Wall said
"We are a group of people who love playing and talking about roller derby
but also giving people who feel like the world has turned their back on them and give them a home
A safe place where they can be whomever they want to be
Alloway goes to teammates for things not related to derby
"I feel comfortable talking to them about so many things
and they always make my emotions feel valid," she said
"We always uplift each other in every way we can
Damon said she was "whole-heartedly welcomed" by the team
and have lent advice for not just Final Girl
And that's why I feel like being an ERD member extends beyond the rink," she said
Wall said ERD is "a safety net of people who will just let you be a shoulder to cry on
I have found genuine friends for the first time in years that I feel like I can trust with parts of my life I hold close to my chest
They fill a hole I had in my life that I didn't realize was truly missing."
"We don't see anyone as anything other than human
We ask preference and we stick to that unless we are told otherwise
It's a sign of respect and acceptance and it's a nonnegotiable to any person on the team."
Erie Roller Derby will take on the Black Diamond Rollers out of Elmira
Tickets are $10 in advance or $15 at the door and are free for ages 10 and younger

This study was conducted to identify characteristics of the perceptual threshold level and electroencephalogram (EEG) responses to vibrotactile stimulations at various high frequencies
and to examine the possibility of distinguishing vibrotactile stimulations by frequency through such response characteristics
The vibrotactile stimulations of six frequencies (150
275 and 300 Hz) were exerted on the first joint of the right index finger
The perceptual threshold level was defined as the first minimum perceived intensity when the intensity stimulation was exerted step by step at each vibration frequency
EEG response characteristics were investigated by examining a single index corresponding to the peak or area of event-related desynchronization/synchronization (ERD/ERS) and seven specific indices derived by combining the single ERD/ERS indices
There was a significant difference in the perceptual threshold level across different frequencies
the differences in vibration stimulus between 150 Hz and 200 Hz
and between 150 Hz and 225 Hz were significant
the single index of the peak or area of ERD/ERS did not show a significant difference by frequency
and ERS × (ERS−ERD) showed a significant difference between vibration stimulations at 150 Hz and 200 Hz
and between vibration stimulations at 150 Hz and 225 Hz
among the specific indices combined using the peak values of ERD/ERS
ERS × (ERS−ERD) showed a significant difference between 150 Hz and 225 Hz
and between 225 Hz and 275 Hz among the specific indices combined using the area of ERD/ERS
The perceptual threshold level and the specific indices of ERD/ERS suggested in the present study can be used as quantitative measurement indices to distinguish high-frequency vibration stimulation
To utilize in devices considering the features of tactile information processing
vibrotactile information should be clearly distinguished in a quantitative fashion
recent work has used electroencephalogram (EEG) features to detect quantitative distinctions of vibrotactile information
Several studies have examined ERD and ERS features for vibrotactile stimulation. For example, Spitzer et al. (2010) generated vibrotactile stimulation at a frequency of 16–41 Hz for the index finger, which can be perceived as flutter, to examine the ERD/ERS features. Neuper and Pfrurtscheller (2001) also considered ERD/ERS features by generating a vibrotactile stimulation at a frequency of less than 22 Hz on the hand and foot
These two studies shared some commonalities
vibrotactile stimulations were classified by controlling the frequency
which is the most fundamental physical trait of vibration
no stimulation more intense than a “flutter” was considered from a qualitative perspective
even though the physical classification is available for low- and high-frequency vibrotactile stimulation
Although examining the use of an EEG index for classification of very minute vibrations is important
the disadvantage is low applicability for devices requiring stimulation that can be qualitatively distinguished at the human perception level
another disadvantage is that only a single index of ERD and ERS is used
Although ERD and ERS are sensitive to physical movement
in order to ensure that vibrotactile information is clearly distinguished and perceived
it is necessary to add specific indices that can amplify the excitatory and inhibitory effects of ERD/ERS of high-frequency vibration stimulations as well as low-frequency vibration stimulations
it would be possible to distinguish the high-frequency vibrotactile stimulations by frequency using more specific indices that amplify the excitatory and inhibitory effects of ERD/ERS
as well as the basic information of ERD/ERS as EEG indices sensitive to physical movement due to the nature of vibrotactile stimulations
An effective approach to vibrotactile stimulation is to utilize frequencies that can be qualitatively distinguished at the human perceptual level
This study thus examined the features of seven ERD/ERS indices segmented with vibrotactile stimulations of relatively high frequencies (150–300 Hz) compared to preceding studies in order to determine whether or not these indices can be used for detailed classification of vibrotactile stimulation
This study was carried out in accordance with the recommendations of the Institutional Review Committee of Konkuk University
and written informed consent was obtained from all subjects in accordance with the Declaration of Helsinki (KU-IRB-11-46-A-1)
A vibrating stimulation was exerted with the use of a vibration stimulation system developed by our research team (Chung et al., 2014). The developed system generates vibrations by sending a sinusoidal electric signal to the solenoid coil and using a Lorentz force that is electromagnetically generated by interaction with an external magnetic field (Figure 1)
The stimulation frequency could be controlled within a range of 0–400 Hz
The stimulation intensity could be controlled in 20 stages
Stimulation was controlled with the use of E-Prime S/W (Psychology Software Tools
The area of contact between the solenoid coil and finger was 1.8 × 1.8 cm2
Before the experiment to measure the EEG, we examined the perceptual threshold level for different intensities of six vibration frequencies: 150, 200, 225, 250, 275 and 300 Hz. The perceptual threshold level was defined as the stimulation at the minimum intensity that the subject perceived for each vibration frequency. The experimental trial to examine perceptual threshold level comprised a rest phase (6 s) and stimulation phase (0.1 s; Figure 1)
relaxed condition without any stimulus being applied
a certain stimulation intensity was exerted at a certain vibration frequency to the first joint of the right index finger of the subject
275 and 300 Hz) and intensity (level 1–20) were exerted in sequence
and the level of stimulation intensity at which the subject felt the vibration for each frequency was determined
In order to verify the significant difference in perceptual threshold level obtained for each frequency
a repeated one-way analysis of variance (ANOVA; PASW Statics 18) was conducted
Bonferroni analysis was carried out for post hoc verification
The experimental trial to measure the EEG also comprised a rest phase (6 s) and stimulation phase (0.1 s; Figure 1)
The rest phase was the state in which no vibration stimulation was exerted
different intensities of six vibration stimulations (150
A total of 60 trials were conducted by randomly repeating the stimulation of six vibration frequencies 10 times
and there was a 10–min break between each session
30 stimulations were exerted at each vibration frequency
which was a stimulation intensity that could be perceived at all frequencies based on the results of the initial perceptual threshold experiment
was used as the stimulation intensity for the EEG experiment
Neural signals were recorded using an EEG device (Quick Amp
EEGs were measured at a sampling frequency of 500 Hz
Based on the 10–20 electrode system
Ag/AgCl electrodes were placed over a total of 16 locations (AF3/4
which is the somatic sensory domain (Somatosensory area in the left hemisphere)
In order to restrict stimulations other than vibration (e.g.
external visual factors were blocked with the use of a black partition
Each subject was instructed to place his arm on the desk with a vibration stimulator while in a comfortable sitting position on a chair
The experiment started when the EEG was stable with limited body movement
Acquired data were analyzed with MATLAB (Mathworks
Bandpass filtering was conducted at 0.5–40 Hz after channel location of the acquired data
Because the vibration stimulation was exerted on the right index finger
detailed analysis was conducted regarding the somatic sensory domain of the contralateral side (i.e.
The recorded EEG signals were filtered using a Butterworth filter (0.1–50 Hz)
The data of one participant was discarded because of abnormal impedance range
Once the EEG had been divided into epochs from 0.5 s before stimulation to 3 s after stimulation for each vibration frequency and short-time Fourier transform (sTFT) was conducted for spectrum analysis over a total period of 3.5 s
The sTFT data were divided into three frequency bands: the alpha domain (10–13 Hz)
and sensorimotor rhythm (SMR) domain (10–30 Hz)
which was subtracted from the log after squaring the sTFT value
After all trials of each subject were averaged
the data from all subjects were averaged to calculate the average power
By calculating the average power value for the three frequency domains
the peak and area of ERD and ERS were extracted
The peak and area were extracted by comparing the power values before stimulation (0 s) to 1 s after stimulation for ERD and between 1 s and 3 s after stimulation for ERS
Along with the peak and area of ERD and ERS for the three frequency domains
the following seven indices were also calculated: ERS − ERD
These seven indices were calculated from the peak and area of ERD and ERS in the alpha domain (10–13 Hz)
and the same calculation was conducted in the beta and SMR domain
Based on a reference that suggested a significant change in the ERD signal in the alpha domain and ERS signal in the beta domain due to tactile stimulation
the seven indices were each calculated using ERD (peak and area) in the alpha domain and ERS (peak and area) in the beta domain
Reliability analysis was conducted to verify the reliabilities of the peak and area values of both ERD/ERS extracted from the trials of each subject and the seven indices to which ERD/ERS were applied
The results showed that all values of Cronbach’s alpha
which indicates a high level of reliability
In order to verify whether or not there was a significant difference in vibration frequencies measured by the seven indices and the peak and area of ERD and ERS
a one-way repeated ANOVA (PASW Statistics 18) was conducted
and Bonferroni analysis was conducted for post hoc verification
linear-by-linear association was used to examine the association between perceptual threshold level and each index value
Figure 2 shows the perceptual threshold level for each frequency
The mean and standard deviation (SD) of the perceptual threshold level was 8.05 ± 2.99 at 150 Hz
There was a significant difference in the perceptual threshold level for each frequency (p < 0.001)
The post hoc verification showed a significant difference in perceptual threshold level between 150 Hz and 200 Hz (p = 0.002) and between 150 Hz and 225 Hz (p = 0.006)
the perceptual threshold level was lower at 200 and 225 Hz compared to at 150 Hz
which indicates high sensitivity to the vibrotactile frequency
Mean value of the perceptual threshold level of all subjects for each frequency
the above three index values were higher for vibration frequencies of 200 Hz and 225 Hz compared to at 150 Hz
The analyses of the association of perceptual threshold level with the three indices that showed a significant difference revealed that there was a significant difference in ERS − ERD (p = 0.047) and ERS × (ERS − ERD; p = 0.031)
whereas no significant difference was observed in ERD × (ERS − ERD; p = 0.100)
Findings for seven types of indices calculated with the peak of the event-related desynchronization (ERD) in the alpha domain and event-related synchronization (ERS) in the beta domain
Findings for seven types of indices calculated with the area of the ERD in the alpha domain and ERS in the beta domain
Findings for three types of indices that presented significant differences in statistical analysis using the peak of the event-related desynchronization (ERD) and event-related synchronization (ERS): (A) ERS − ERD (B) ERS × (ERS − ERD) (C) ERD × (ERS − ERD)
The association of perceptual threshold level with the two indices that showed a significant difference was examined and a significant difference was found in both ERS − ERD (p = 0.044) and ERS × (ERS − ERD; p = 0.050)
Findings for two types of indices that presented significant differences in statistical analysis using the area of the ERD and ERS: (A) ERS − ERD (B) ERS × (ERS − ERD)
The objective of this study was to examine whether vibrotactile stimulation can be perceptually distinguished at high frequencies and quantified with ERD/ERS indices. The results showed a difference in the perceptual threshold level between 150 Hz and 200 Hz and between 150 Hz and 225 Hz for each frequency of the vibrotactile stimulation. These results correspond to those of Mountcastle et al. (1972)
who suggested that humans are most sensitive to detection thresholds when the vibration frequency is 200–250 Hz
The sensitivity to frequency bands coincides with the sensitivity of Pacinian corpuscles
the perceptual distinction of vibrotactile stimulation at high frequencies may be dependent on the sensitive receptive field of Pacinian corpuscles
Although the EEG findings of this study were limited to the C3 domain
the possibility of such an interpretation cannot fully be excluded considering the low spatial resolution; this represents one limitation of the present study
there was a distinctive magnitude difference in vibrotactile stimulation at 150 Hz and 200 Hz that could be perceived with the (ERS − ERD) index
Vibrotactile stimulations of 275 Hz and 300 Hz
which had a similar perceptual threshold as 200 Hz
also displayed an outstanding magnitude difference with vibrotactile stimulation of 200 Hz according to the (ERS − ERD) index
Because the (ERS − ERD) index displays the size of the total effect reflecting both excitatory and inhibitory effect followed by vibrotactile stimulation
it can be considered to calculate the amount of energy attributable to vibrotactile stimulation
the ERS × (ERS − ERD) index
which amplifies the size effect of ERS considering the energy attributable to vibrotactile stimulation
clearly distinguishes the magnitude of the vibrotactile stimulation at 150 Hz and 225 Hz
The ERD × (ERS − ERD) index was found to clearly distinguish the magnitudes of the vibrotactile stimulation between 150 Hz and 200 Hz and between 200 Hz and 250 Hz
Extracting the common feature of all three indices not only clearly distinguished the vibrotactile stimulations of 150 Hz and 200–225 Hz at the perceptual threshold level but also markedly distinguished each vibrotactile stimulation to reflect the feature of the ERD/ERS single index
which only presented the inclination due to the small size of the effect
the above three indices can be used for quantitative measurement to clearly distinguish high vibration frequencies
this study is significant in that it explored new indices based on ERD/ERS
while previous studies mainly examined the feature of ERD/ERS with regard to vibrotactile stimulations
a method was developed that enables more distinctive extraction of the feature of the ERD/ERS single index
the new index needs to be validated through future studies on vibrotactile stimulations

Movement-related oscillations in the beta range (from 13 to 30 Hz) have been observed over sensorimotor areas with power decrease (i.e.
ERD) during motor planning and execution followed by an increase (i.e.
Several electrophysiology studies have used beta ERD and ERS as functional indices of sensorimotor integrity
primarily in diseases affecting the motor system
Recent literature also highlights other characteristics of beta ERD and ERS
implying their role in processes not strictly related to motor function
Here we review studies about movement-related ERD and ERS in diseases characterized by motor dysfunction
We also review changes of beta ERD and ERS reported in physiological aging
three conditions without overt motor symptoms
The review of these works shows that ERD and ERS abnormalities are present across the spectrum of the examined pathologies as well as development and aging
They further suggest that cognition and movement are tightly related processes that may share common mechanisms regulated by beta modulation
Future studies with a multimodal approach are warranted to understand not only the specific topographical dynamics of movement-related beta modulation but also the general meaning of beta frequency changes occurring in relation to movement and cognitive processes at large
Such an approach will provide the foundation to devise and implement novel therapeutic approaches to neuropsychiatric disorders
No matter the precise significance of beta ERD, ERS, and movement-related beta modulation in general, all past studies have considered them as hallmark of the sensorimotor system functioning (Espenhahn et al., 2017) and thus
as possible biomarkers of motor symptoms in several neurological and psychiatric diseases
movement-related beta activity has been extensively studied in patients with Parkinson’s disease (PD)
the second most common neurodegenerative disorder that is still diagnosed with the appearance of motor symptoms
only a few studies focused on cognitive and behavioral disorders that are not specifically characterized by motor symptoms
conditions where subclinical motor or sensorimotor abnormalities can be experimentally detected
we wished to answer the following questions: Are abnormalities of movement-related beta ERD and ERS clearly and specifically linked to motor symptoms
Are these abnormalities present in pathological conditions other than classical motor disorders
We thus focused on studies investigating movement-related ERD and ERS in the beta range during motor tasks performed with a limb and recorded with electrophysiological techniques with high time resolution (such as EEG
and DBS) that allows for differentiating phases of planning
The reviewed papers were on pathologies both specifically affecting the motor system [e.g.
(MS)] and in conditions that are not strictly associated with motor disorders
The research of the literature did not disclose studies about beta ERD or ERS in other psychiatric conditions
The results of this review indicate that abnormalities of movement-related beta ERD and ERS have been described not only in classical motor disorders but also in pathologies that do not present with overt motor signs
such electrophysiological abnormalities do not appear to be specifically linked to motor symptoms but
they were rather associated to non-motor problems
the review of those studies suggests that beta ERD and ERS cannot be considered pure biomarkers of specific motor aspects
but they rather represent neural mechanisms common to features of motor and non-motor functions
Throughout the present paper, we use the terminology of beta ERD to indicate decreases of beta power before and during movement and beta ERS for increases of beta power after movements. A description of all the retrieved studies is reported in Tables 1–4. A summary of the results are in Table 5

Summary of the results of EEG and MEG studies in neuropsychiatric diseases
While there is no clear explanation for these phenomena
one could speculate that the prolonged ERD is due to the loss of the appropriate neuronal population to be recruited
so that greater neuronal loss is associated with longer ERD duration and poorer motor performance
the reviewed studies suggest that that abnormalities of ERD and ERS in stroke patients are somewhat related to abnormal motor function in general or specifically during the motor task
see supplemental material) that was proportional to the degree of corticospinal damage
The contrasting results of the two studies could be due to differences in the selections of the range of beta band
The reviewed studies indicate that, in general, the finding of abnormal ERD/ERS in ALS did not directly relate to motor dysfunction, the main problem of this disease. However, correlation between cognitive scores with ERS amplitude was reported at least in one study (McMackin et al., 2021)
This suggests that movement-related beta ERD/ERS may reflect cognitive problems that often accompany ALS in the absence of motor task performance disruption
many factors could have played a role in the diverse results
the great number of tested variables as well as large within- and between-group variabilities in terms of age
Greater coherence between DBS and MEG recordings in beta frequency range was associated with increased reaction time
confirming the role of beta oscillations in motor planning
While ERD amplitude was similar in non-fatigued MS patients and healthy controls
the fatigued MS patients displayed a smaller ERD than the other two groups
The greater fatigue scores corresponded to a larger ERD reduction
suggesting that non-motor features may contribute to ERD amplitude
confirming a disruption of beta ERS mechanisms
The authors further suggested that neuronal damage in MS
either from decreased neuronal density or demyelination
may lead to a decrease in neuronal firing and thus to a reduced ability to synchronize
The authors stated that the lack of difference in terms of occipital beta ERD is possibly related to intact occipital function in this group of participants compared to the previous one
An alternative explanation should take into account the lack of online visual feedback during the task compared to the other studies
greater ERD amplitude was associated with slower walking cadence
suggesting that increased ERD amplitude in CP may result from abnormalities in energy regulation
Many of these papers also reported delayed timing of ERD
The contrasting results of these papers could be due to differences in tasks, sample size, and age ranges. Most importantly, age may not be the best predictor of cortical changes since other individual factors play important roles in aging processes, such as motor practice, lifestyle, gender, genetics, and differences in plasticity and energy mechanisms (Dachtler and Fox, 2017; Ricci et al., 2019a)
This review suggests that neurological and psychiatric disorders with or without overt motor problems present with abnormalities of movement-related beta ERD and ERS and that such abnormalities are, in many cases, not directly related to motor symptoms. As summarized in Table 5
most studies found decreased ERD amplitude in stroke
and PD; decreased ERD and ERS amplitudes were described in MS
especially in patients with fatigue; conversely
ERD with abnormally increased amplitude was reported in CP
a process accompanied by changes in motor and cognitive function
ERD and ERS amplitudes increase during development
a finding that has been linked to the reduced cortical inhibition and high plasticity typical of childhood
contrasting results about the effects of old age suggest that age per se is not associated with changes in movement-related beta oscillations and other factors related to lifestyle
and perhaps genetics may play significant roles
Only a few studies have investigated possible changes in neuropsychiatric conditions without clinically evident sensorimotor impairment
and ERS associated with simple finger movements were spread beyond the normal motor cortical network over areas that
Such an enlarged recruitment suggests that first
neurodegeneration in AD must also affect the sensorimotor function
which is often present later on in the disease
Decreased ERS amplitude correlated with the progression of schizophrenia and also with the degree of schizotypal personality; in OCD
similar ERS findings were not related to motor performance
abnormalities of movement-related beta ERD and ERS were found in all the neuropsychiatric diseases we have reviewed and such abnormalities were not necessarily dependent on the presence of motor symptoms
it is likely that cognition and movement share common processes –both regulated by beta modulation – that allow for focusing and suppressing irrelevant phenomena
with a sort of center-surround suppression mechanism of action
This view of common mechanisms underlying motor and cognitive processes
such as those expressed by beta modulation
transcends the conceptual separation of the different brain functions into motor and cognitive categories and should ultimately guide new research approaches for finding more effective therapeutical solutions
and thus to address symptoms with novel approaches
These are only a small sample of the many facets that need to be uncovered by research on movement-related beta ERD and ERS
an effort that needs a comprehensive multimodal translational approach
is essential to define targeted therapeutical interventions for the care of many motor and non-motor features of neuropsychiatric diseases

With a CR2032 battery life of 50,000 hours
you can rely on it to be ready when go-time comes around
The optic automatically shuts off after five minutes of inactivity and turns back on with the shake-awake function we’ve come to expect from modern red dots to maximize battery life
Accuracy can mean different things in different situations
You’ll get a 2-MOA dot for shooting tight groups that’s adjustable in 1-MOA increments
you can activate a multi-reticle like the ones popularized by Holosun and use a 56-MOA ring around the dot to get on target as quickly as possible
There are 10 brightness settings (two are compatible with night vision) that you can toggle through with up and down switches on the left side of the optic
it uses a standard Picatinny rail mounting pattern
C&H Precision lists an MSRP of $494.95 for the ERD-1
I haven’t gotten my hands on the ERD-1 yet, but I spent several days training with C&H Precision’s pistol optics a few weeks back. They were rock-solid during dynamic day shoots and night shoots, as well as maneuvering in and around vehicles. I even landed a hit on a steel silhouette with a Walther PDP F-Series from about 120 yards away

Teletalk looks forward to the Economic Relations Division (ERD) as the lone state telecom operator's 4G mobile broadband network expansion project remains stalled following cancellation of its first tender.The operator is now weighing multiple options -- whether to select one of the three original companies
issue a new tender among all of them or exclude the previous entities and invite fresh bids.To navigate this situation
Teletalk sought guidance from the Bangladesh Public Procurement Authority (BPPA) through a letter on February 18
the BPPA recently provided opinion in a letter signed by its director (deputy secretary) Sakhawat Hossain
stating that the public procurement rules and associated policies outline the procedures for cancelling all tenders under such circumstances.The BPPA advised the Teletalk authorities to proceed accordingly.In light of this
the BPPA suggested that Teletalk consult the ERD to explore the possibility of replacing the disqualified EPC (engineering
procurement and construction) firms with new
highly qualified ones.Industry experts argue that the disqualified trio violated tender rules and should be obstructed for new bid
with a fresh tender process initiated.Teletalk managing director Nurul Mabud Chowdhury confirmed that they have decided to send a letter to the ERD in line with the BPPA's advice."We're following government rules
and the ERD circular on this issue will guide the next steps," he said
adding that the ERD will make the final decision.Bangladesh's ties with China have been strengthened in recent years
with Beijing providing $2.97 billion in loans over the last four fiscal years.For Teletalk's 4G expansion project
China has committed approximately Tk 20 billion (about $162 million)
while the Bangladesh government is contributing Tk 9.0 billion.Under the government-to-government (G2G) framework
China was supposed to nominate three companies for the project.However
all three bidders were disqualified due to irregularities in the tender process
with allegations of a syndicate forming among them.A development expert and communication specialist emphasised that while China has been a key development partner
national interests must not be compromised
"Transparency and accountability are essential
Bangladesh should ensure fair competition."Again
a Teletalk SIM user echoed similar concerns
stating: "The biggest issue with any project in our country is transparency
We should not compromise our independence just because China is financing the project
Teletalk must protect its own interests."bdsmile@gmail.com
Bishop Daniel Flores addresses the USCCB plenary assembly June 16, 2023.Share
The proposal to review Part Three of the Ethical and Religious Directives for Catholic Health Care Services passed unanimously on a voice vote on the final day of the USCCB’s plenary assembly in Orlando
The Ethical and Religious Directives for Catholic Health Care Services (ERDs) is a guide released by the bishops to offer ethical standards in health care
based on Catholic teaching about human dignity
which was approved by the bishops five years ago
dealing with professional-patient relationships
It does not include guidance on “radical modifications of the human body,” such as surgeries and hormones given for gender dysphoria
In March, the USCCB’s administrative committee authorized the publication of a doctrinal note from the conference’s doctrine committee on “moral limits to technological manipulation of the human body.”
The note said, among other things, that transgender surgeries are immoral because they “do not repair a defect in the body…these interventions are intended to transform the body so as to make it take on as much as possible the form of the opposite sex, contrary to the natural form of the body. They are attempts to alter the fundamental order and finality of the body and to replace it with something else.”
Flores introduced a proposal to incorporate the doctrinal note into the ERDs. The revision would involve the doctrine committee consulting bishops, moral theologians, doctors and other experts to create a draft that would be subject to review, discussion, and vote by the bishops.
When Flores asked if there were any questions, several bishops came forward to emphasize that they believe there should be a “broad consultation” on the issue, including the voices of people who identify as transgender.
Cardinal Robert McElroy of San Diego made a distinction between “the doctrinal tradition of the Church, particularly on male and female” and the need “to wrestle with the existential question of those who are suffering from dysphoria.”
“I think there’s a fundamental difference between a declaration on doctrine, which was issued, and the formulation of the ERDs,” he said.
He stressed that the ERDs are not just a statement of doctrine but an application of doctrine to “the existential situation of people who are suffering.”
“The ERDs are meant to be a pastoral, medical document to inform and guide the health care ministries,” he said.
“I urge therefore that the consultation be very wide and deep, within the medical communities and with people who are suffering from dysphoria also,” he said.
Cardinal Joseph Tobin emphasized the need to listen to people and to present things in a way that is understandable to people in the language of the ERDs.
“I would like to also encourage a broad consultation, including people who are from the trans community,” he said.
Bishop Shawn McKnight of Jefferson City also called for a “wide consultation, especially with the various Catholic health care systems.”
Auxiliary Bishop Robert Casey of Chicago, speaking on behalf of Cardinal Blase Cupich, who had to leave the meeting early, asked that the consultation include dioceses with a significant Catholic health care presence.
Archbishop Paul Etienne of Seattle also called for a “broader consultation,” saying that policy makers, physicians, and CEOs of health care systems should all be able to weigh in on the discussion.
Bishop Michael Olson of Fort Worth, who is a member of the doctrine committee that released the note on technological manipulation of the human body in March, emphasized that there had been extensive consultation leading up to the development of that note.
“Part of the process that we had in the doctrinal note was listening not only to members who identify themselves as part of the trans community, but those practitioners, theologians, ethicists, family members as well,” he said.
“And what became clear in this process as we compiled and formed the doctrinal note is that there is still a lack of clarity between what is authentic gender dysphoria and then also the gender ideology that in part is preying upon these people and enhancing their suffering, increasing their suffering,” he continued.
“So I’m hoping that the development and the process of the ERDs will help us to bring greater clarity between these two phenomena, of gender dysphoria and also gender ideology. So then hopefully we can write a broader pastoral document after the completion of the ERDs.”
After fielding questions and comments, the bishops held a voice vote on the proposal. The vote passed unanimously, with no abstentions or votes in opposition.
There never can be broad clarity in these matters because every case has its origin in a single human mind and every mind is unique
Some people are apparently deeply committed to *something like* a belief that God or nature has played them a cruel trick by creating them with a body of the incorrect sex
some have convinced "experts" and a surgeon that the only acceptable solution is sex-reassignment surgery
https://en.wikipedia.org/wiki/Gender-affirming_surgery
Beliefs no doubt vary widely among different subjects, as do those of the experts relied upon. Presumably the surgeons follow standard procedures.

Nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) is a clinical syndrome characterized by nasal polyposis
It affects approximately 15% cases of severe asthma
10% of nasal polyps and 9% of rhinosinusitis
N-ERD results in associated asthma exacerbations
Unknown influences cause polyp epithelium to release alarmins
resulting in complex type 2 inflammation involving mast cells
Arachidonic acid released from such cells is metabolized into mediators
N-ERD is characterized by an imbalance in eicosanoid levels
Patients with N-ERD present nasal symptoms (congestion
nasal discharge) and lower airways symptoms (cough
severe hyposmia as well as severe asthma which impacts the quality of life in this disease and leads to safety concerns in patients daily lives
Despite the variety of treatment strategies
the likelihood of recurrence of symptoms is high in patients with N-ERD
The most important strategies for treating N-ERD are listed as following: drug therapies
monoclonal antibodies and other therapies associated
N-ERD treatment remains a major challenge in the current situation
Selecting the appropriate patient for aspirin desensitization
monoclonal antibodies or both is essential
This review provides an overview on aspirin desensitization and biologics in N-ERD and might help in decision making from both the perspective of the physician and patient
but also patient preferences are all factors to take into account when it comes to a choice between biologics or aspirin desensitization
the physician is left with two treatment options to attack the persistent airway inflammation: aspirin desensitization or biological therapy
no direct trials with aspirin desensitization and biologic therapy in N-ERD patients exist which makes it difficult to choose
The treating physician should therefore be continuously attentive for aspirin-related adverse effects and asses the benefit/risk ratio of aspirin desensitization regularly as patients' history can change
it is unclear whether initiating biologics immediately after surgery would have a better clinical effect
Another important factor to consider is the extent to which the patient can adhere to the treatment. Patients on aspirin treatment after aspirin desensitisation (ATAD) missing their dose for more than two days will gradually regain their intolerance and will need further desensitization (2, 15)
It is therefore of utmost importance to continuously monitor patients for aspirin-related side effects
there are currently no biosimilars for dupilumab
mepolizumab and omalizumab on the market to stimulate market competitiveness and to reduce the costs for the health care system
depending on the turnover threshold of the original biological
the price of a biosimilar can be up to maximum 47,18% lower than the original price of the original biological
The costs must be weighed against effectiveness
expressed by “quality-adjusted life year” (QALY)
which stands for one year in perfect health
In 2008, Shaker et al. investigated the cost-effectiveness of aspirin desensitization with subsequent aspirin therapy in moderate-to-severe N-ERD (34)
According to their findings ambulatory desensitization for N-ERD could save $6.768 per QALY and across a wide range of assumptions
aspirin desensitization remained cost-effective with less than $50,000 per QALY saved
In their modelling of costs of asthma therapy
they did not include the potential of aspirin desensitization to reduce the need for omalizumab
the abovementioned amounts are probably underestimating the cost saving effect of aspirin
Lysine aspirin is more expensive than aspirin tablets
but the process of challenge and initial desensitization is faster
taking half a day rather than 2–3 days of inpatient care
very significantly lower than that of any biologic
A full-scale double- blind trial is needed
Regarding the biologics, not surprisingly, cost-effective analyses are lacking, given their only recent approval for chronic rhinosinusitis. Anderson et al. reviewed in 2019 the current literature for asthma and the cost-efficacy of omalizumab, mepolizumab, reslizumab, benralizumab and dupilumab. The authors concluded that the prices should be reduced by a minimum of approximately 60% to achieve the cost-effectiveness threshold prices (35)
there is something to be said for both biologics and aspirin desensitization
as the costs of aspirin desensitization are nothing compared to biologics
aspirin desensitization should be tried first when no clear contra-indication exists
patients might fear the effect of the biological on their immune system and the fact that only short-term safety data are known
Different factors have to be weighed up continuously
a trial of ATAD should therefore precede treatment with a biologic
the Medical University of Vienna is currently running a study to test the efficacy of a 6-month treatment with dupilumab in inducing tolerance to aspirin evaluated by oral drug provocation testing (ClinicalTrials.gov Identifier: NCT04442256)
The estimated study completion date is foreseen by the end of 2022
