Canada Begins Long Cleanup After Fiona Sweeps Homes Out to Sea

PORT AUX BASQUES, Newfoundland — It will take several months for Canada to restore critical infrastructure after the powerful storm Fiona left an "unprecedented" trail of destruction, officials said Sunday, as crews fanned out in five provinces to restore power and clean up fallen trees and debris.  "It's like a complete war zone," said Brian Button, mayor of Port aux Basques, one of the hardest hit towns on the southwest tip of Newfoundland with just over 4,000 residents. More than 20 homes were destroyed and the cost of damages "is in the millions (of dollars) here now," Button said in an interview.  No fatalities have been confirmed so far, but police in Newfoundland are searching for a 73-year-old woman they suspect was swept out to sea.  "The woman was last seen inside (her) residence just moments before a wave struck the home, tearing away a portion of the basement. She has not been seen since," police said in a statement.  Fiona slammed into eastern Canada Saturday, forcing evacuations as wind gusted up to 170 km per hour (106 miles per hour).  While the full scale of Fiona's devastation is not immediately clear, the storm could prove to be one of Canada's costliest natural disasters.  Scientists have not yet determined whether climate change influenced Fiona, but in general the warming of the planet is making hurricanes wetter, windier and altogether more intense.  Canada's federal government is sending in the armed forces Sunday to help clear fallen trees and debris, which will in turn open the way for crews to restore power, Emergency Preparedness Minister Bill Blair told Reuters.  The province of Nova Scotia requested the troops and machinery to clear debris Saturday, "and we said yes, and so they're being deployed today," Blair said. Other provinces are also in discussions about federal aid, Blair said.  The Canadian Hurricane Center estimated that Fiona was the lowest-pressured storm to make landfall on record in Canada. In 2019, Dorian hit the region around Halifax, Nova Scotia, blowing down a construction crane and knocking out power. Fiona, on the other hand, appears to have caused major damage across at least five provinces.  "The scale of what we're dealing with, I think it's unprecedented," Blair said Sunday.  "There is going to be... several months' work in restoring some of the critical infrastructure - buildings and homes, rooftops that have been blown off community centers and schools," he said.  Hundreds of thousands of residents across Nova Scotia, Prince Edward Island (PEI), Newfoundland, Quebec and New Brunswick remained without power Sunday. Blair said hundreds of utility crews had already been deployed to restore power.  "When it's all said and done... Fiona will turn out to have caused the most damage of any storm we've seen," Nova Scotia Premier Tim Houston told the CBC.  Officials warned Saturday that in some cases it would take weeks before essential services are fully restored.  Prime Minister Justin Trudeau had convened a meeting of his emergency response group for Sunday to coordinate the government's response, according to a statement.  "We do know that the damage is very extensive, quite likely the worst we have ever seen," Dennis King, PEI premier, told reporters Saturday.  "Islanders ... should know that our road to recovery will be weeks or longer. It will be an all-hands-on-deck approach," he added.  The storm also severely damaged fishing harbors in Atlantic Canada, which could hurt the country's C$3.2 billion lobster industry, unless it is fully restored before the season kicks off in a few weeks.  "Those fishers have a very immediate need to be able to access their livelihood once the storm passes," Dominic LeBlanc, minister of intergovernmental affairs of Canada, said Saturday.

Qatar Says Worker Deaths for World Cup 'Between 400 and 500' 

DOHA, Qatar — A top Qatari official involved in the country's World Cup organization has put the number of worker deaths for the tournament "between 400 and 500" for the first time, a drastically higher number than any other previously offered by Doha. The comment by Hassan al-Thawadi, the secretary-general of Qatar's Supreme Committee for Delivery and Legacy, appeared to come off the cuff during an interview with British journalist Piers Morgan. It also threatened to reinvigorate criticism by human rights groups over the toll of hosting the Middle East's first World Cup for the migrant labor that built over $200 billion worth of stadiums, metro lines and new infrastructure needed for the tournament. The Supreme Committee and Qatar's government did not immediately respond to a request for comment Tuesday. In the interview, portions of which Morgan posted online, the British journalist asks al-Thawadi: "What is the honest, realistic total do you think of migrant workers who died from — as a result of work they're doing for the World Cup in totality?" "The estimate is around 400, between 400 and 500," al-Thawadi responds. "I don't have the exact number. That's something that's been discussed." But that figure hasn't been discussed publicly by Qatari officials previously. Reports from the Supreme Committee dating from 2014 through the end of 2021 only include the number of deaths of workers involved in building and refurbishing the stadiums now hosting the World Cup. Those released figures put the total number of deaths at 40. They include 37 from what the Qataris describe as nonwork incidents such as heart attacks and three from workplace incidents. One report also separately lists a worker death from the coronavirus amid the pandemic. Al-Thawadi pointed to those figures when discussing work just on stadiums in the interview, right before offering the "between 400 to 500" death toll for all the infrastructure for the tournament. Since FIFA awarded the tournament to Qatar in 2010, the country has taken some steps to overhaul the country's employment practices. That includes eliminating its so-called kafala employment system, which tied workers to their employers, who had say over whether they could leave their jobs or even the country. Qatar also has adopted a minimum monthly wage of 1,000 Qatari riyals ($275) for workers and required food and housing allowances for employees not receiving those benefits directly from their employers. It also has updated its worker safety rules to prevent deaths. "One death is a death too many. Plain and simple," al-Thawadi adds in the interview. Activists have called on Doha to do more, particularly when it comes to ensuring workers receive their salaries on time and are protected from abusive employers. Al-Thawadi's comment also renews questions on the veracity of both government and private business reporting on worker injuries and deaths across the Gulf Arab states, whose skyscrapers have been built by laborers from South Asia nations like India, Pakistan and Sri Lanka. Mustafa Qadri, the executive director of Equidem Research, a labor consultancy that has published reports on the toll of the construction on migrant laborers, said he was surprised by al-Thawadi's remark. "For him now to come and say there is hundreds, it's shocking," he told The Associated Press. "They have no idea what's going on."

Associations Between Patient/Caregiver Trust in Clinicians and Experiences of Healthcare-Based Discrimination

Background:

Higher trust in healthcare providers has been linked to better health outcomes and satisfaction. Lower trust has been associated with healthcare-based discrimination.

Objective:

Examine associations between experiences of healthcare discrimination and patients’ and caregivers of pediatric patients’ trust in providers, and identify factors associated with high trust, including prior experience of healthcare-based social screening.

Methods:

Secondary analysis of cross-sectional study using logistic regression modeling. Sample consisted of adult patients and caregivers of pediatric patients from 11 US primary care/emergency department sites.

Results:

Of 1,012 participants, low/medium trust was reported by 26% identifying as non-Hispanic Black, 23% Hispanic, 18% non-Hispanic multiple/other race, and 13% non-Hispanic White (P = .001). Experience of any healthcare-based discrimination was reported by 32% identifying as non-Hispanic Black, 23% Hispanic, 39% non-Hispanic multiple/other race, and 26% non-Hispanic White (P = .012). Participants reporting low/medium trust had a mean discrimination score of 1.65/7 versus 0.57/7 for participants reporting high trust (P < .001). In our adjusted model, higher discrimination scores were associated with lower trust in providers (aOR 0.74, 95%CI = 0.64, 0.85). A significant interaction indicated that prior healthcare-based social screening was associated with reduced impact of discrimination on trust: as discrimination score increased, odds of high trust were greater among participants who had been screened (aOR = 1.28, 95%CI = 1.03, 1.58).

Conclusions:

Patients and caregivers reporting more healthcare-based discrimination were less likely to report high provider trust. Interventions to strengthen trust need structural antiracist components. Increased rapport with patients may be a potential by-product of social screening. Further research is needed on screening and trust.

Association between a recalled positive airway pressure device and incident cancer: a population-based study

Background

The real-world consequences of a Philips Respironics recall for positive airway pressure (PAP) devices distributed between 2009 and 2021 are unknown.

Methods

We conducted a retrospective population-based study using health administrative databases (Ontario, Canada) on all new adult PAP users identified through the provincial funding system, free of cancer at baseline, who initiated (claimed) PAP treatment between 2012 and 2018. Everyone was followed from the PAP claim date to the earliest of incident cancer diagnosis, death or end of follow-up (March 2022). We used inverse probability of treatment weighting to balance baseline characteristics between individuals on recalled devices and those on devices from other manufacturers. Weighted hazard ratios of incident cancer were compared between groups.

Results

Of 231 692 individuals identified, 58 204 (25.1%) claimed recalled devices and 173 488 (74.9%) claimed devices from other manufacturers. A meaningful baseline difference between groups (standardised difference ≥0.10) was noted only by location-relevant covariates; other variables were mostly equally distributed (standardised differences ≤0.06). Over a median (interquartile range) follow-up of 6.3 (4.9–8.0) years, 11 166 (4.8%) developed cancer: unadjusted rates per 10 000 person-years of 78.8 (95% CI 76.0–81.7) in the recall group versus 74.0 (95% CI 72.4–75.6) in others (p=0.0034). Propensity score weighting achieved excellent balance in baseline characteristics between groups (standardised differences ≤0.07). On a weighted sample, there was no statistical difference in the hazard of incident cancer between groups: cause-specific hazard ratio (recalled versus others) 0.97 (95% CI 0.89–1.06).

Conclusion

In our real-world population study, compared to other manufacturers and adjusting for confounders, recalled Philips Respironics PAP devices do not appear to be independently associated with developing cancer.

Collaborative discussions between GPs and pharmacists to optimise patient medication: a qualitative study within a UK primary care clinical trial

BackgroundThere has been significant investment in pharmacists working in UK general practice to improve the effective and safe use of medicines. However, evidence of how to optimise collaboration between GPs and pharmacists in the context of polypharmacy (multiple medication) is lacking.AimTo explore GP and pharmacist views and experiences of in-person, interprofessional collaborative discussions (IPCDs) as part of a complex intervention to optimise medication use for patients with polypharmacy in general practice.Design and settingA mixed-method process evaluation embedded within the Improving Medicines use in People with Polypharmacy in Primary Care (IMPPP) trial conducted in Bristol and the West Midlands, between February 2021 and September 2023.MethodAudio-recordings of IPCDs between GPs and pharmacists, along with individual semi-structured interviews to explore their reflections on these discussions, were used. All recordings were transcribed verbatim and analysed thematically.ResultsA total of 14 practices took part in the process evaluation from February 2022 to September 2023; 17 IPCD meetings were audio-recorded, discussing 30 patients (range 1–6 patients per meeting). In all, six GPs and 13 pharmacists were interviewed. The IPCD was highly valued by GPs and pharmacists who described benefits, including: strengthening their working relationship; gaining in confidence to manage more complex patients; and learning from each other. It was often challenging, however, to find time for the IPCDs.ConclusionThe model of IPCD used in this study provided protected time for GPs and pharmacists to work together to deliver whole-patient care, with both professions finding this beneficial. Protected time for interprofessional liaison and collaboration, and structured interventions may facilitate improved patient care.

Iraqi, Kurdish forces in standoff, weeks after Kurdish vote for independence

Watch Video | Listen to the Audio

HARI SREENIVASAN: The desire of the Kurds along Iraq’s northern border to govern themselves is receiving more resistance from Iraq’s central government. Iraqi army forces are demanding Kurdish troops withdraw from oil fields and military bases around Kirkuk, a city in the Kurdistan region that voted for independence last month. Kirkuk also has 10% of Iraq’s known oil reserves. Washington Post’s Loveday Morris is in Baghdad covering this standoff joins me now via Skype. First of all the significance of this. Why is it so important?

LOVEDAY MORRIS: There’s been a longtime conflict between Baghdad and Kurdistan over these disputed territories. Most significant of which is Kirkuk because of the oil reserves. But the referendum last month has really sharpened these disputes because you have Baghdad opposing independence and so it feels like they have to restate its territorial claims these areas. So that’s why we’re seeing a lot of tension right now.

HARI SREENIVASAN: And just to give people a little bit of a brief timeline – Iraqi forces control this area for a while and then in June ISIS took over the area and now it’s kind of back in Kurdish hands?

LOVEDAY MORRIS: Right. So in June 2014 Iraq lost control of a lot of the areas and we have this huge collapse in the face of an ISIS offensive. Over 100,000 soldiers fled and Kurdish forces moved in some of these areas – some of them maybe took from ISIS and others just moved into into the vacuum. And so Iraqi forces have been in these areas since June 2014. And that’s their main demand that they return to the areas.

HARI SREENIVASAN: What’s the likelihood that this standoff right now turns violent? Into some sort of a civil war?

LOVEDAY MORRIS:: I think at this point both sides don’t want violence. Al-Abadi, the prime minister, is really trying to defuse the situation by saying there’s going to be no military attack. But at the same time there is this buildup of forces so that I think they are trying to, in a way, intimidate the Kurds to withdraw from some areas but they don’t want to see a fight per say. But in this really tense situation there can be a small spark and things can turn violent quite easily.

HARI SREENIVASAN: Thank you.
