Unequal impact of the COVID-19 pandemic in 2020 on life expectancy across urban areas in Chile: a cross-sectional demographic study

Objectives
To quantify the impact of the COVID-19 pandemic on life expectancy in Chile categorised by rural and urban areas, and to correlate life expectancy changes with socioeconomic factors at the municipal level.

Design
Retrospective cross-sectional demographic analysis using aggregated national all-cause death data stratified by year, sex and municipality during the period 2010–2020.

Setting and population
Chilean population by age, sex and municipality from 2002 to 2020.

Main outcome measures
Stratified mortality rates using a Bayesian methodology. These were based on vital and demographic statistics from the national institute of statistics and department of vital statistics of ministry of health. With this, we assessed the unequal impact of the pandemic in 2020 on life expectancy across Chilean municipalities for males and females and analysed previous mortality trends since 2010.

Results
Life expectancy declined for both males and females in 2020 compared with 2019. Urban areas were the most affected, with males losing 1.89 years and females 1.33 years. The strength of the decline in life expectancy correlated positively with indicators of social deprivation and poverty. Also, inequality in life expectancy between municipalities increased, largely due to excess mortality among the working-age population in socially disadvantaged municipalities.

Conclusions
Not only do people in poorer areas live shorter lives, they also have been substantially more affected by the COVID-19 pandemic, leading to increased population health inequalities. Quantifying the impact of the COVID-19 pandemic on life expectancy provides a more comprehensive picture of the toll.

Heterogeneous impact of the COVID-19 pandemic on lung, colorectal and breast cancer incidence in Hungary: results from time series and panel data models

Objective
During the COVID-19 pandemic, health system resources were reallocated to provide care for patients with COVID-19, limiting access for others. Patients themselves also constrained their visits to healthcare providers. In this study, we analysed the heterogeneous effects of the pandemic on the new diagnoses of lung, colorectal and breast cancer in Hungary.

Design
Time series and panel models of quarterly administrative data, disaggregated by gender, age group and district of residence.

Participants
Data for the whole population of Hungary between the first quarter of 2017 and the second quarter of 2021.

Main outcome measures
Number of patients newly diagnosed with lung, colorectal and breast cancer, defined as those who were hospitalised with the appropriate primary International Classification of Diseases Tenth Revision diagnosis code but had not had hospital encounters with such a code within the previous 5 years.

Results
The incidence of lung, colorectal and breast cancer decreased by 14.4% (95% CI 10.8% to 17.8%), 19.9% (95% CI 12.2% to 26.9%) and 15.5% (95% CI 2.5% to 27.0%), respectively, during the examined period of the pandemic, with different time patterns across cancer types. The incidence decreased more among people at least 65 years old than among the younger (p

Impact of COVID-19 pandemic on medical students: a scoping review protocol

Introduction
The COVID-19 pandemic has spread globally and has been reported in every known country. The effects can be felt in universities and schools, shifting their learning to online platforms. However, medical schools bear the burden of protecting students and ensuring the continuation of the education process. The rapid transition to online learning, coupled with the lack of preparation from the educational system, leads to stresses that affect students’ academic performance, mental health and social life. Nevertheless, no review tried to synthesise the complete picture of the pandemic’s effects. Therefore, this scoping review aims to identify and explore the available literature on the effects or impacts of the pandemic on medical students without limiting it to specific dimensions.

Methods
This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews and the Joanna Briggs Institute manual for evidence synthesis. We examine articles reporting data from any country. However, only articles written in English will be included. For studies to be included, they must report any form of impact on medical students, qualitatively or quantitatively. Furthermore, the impact must occur within the context of the COVID-19 pandemic. Searches will be done on Medline, EMBASE, ERIC, the Cochrane Library, CINAHL and PsycInfo. After data extraction, we will narratively synthesise the data and explore the types of impacts COVID-19 has on medical students.

Ethics and dissemination
No formal ethical approval is required. The scoping review will be published in peer-reviewed journals and as conference presentations and summaries, wherever appropriate.

Patient lead users experience of the COVID-19 pandemic: a qualitative interview study

Objectives
Patient lead users can be defined as patients or relatives who use their knowledge and experience to improve their own or a relative’s care situation and/or the healthcare system, and who are active beyond what is usually expected. The objective of this study is to explore patient lead users’ experiences and engagement during the early COVID-19 pandemic.

Design
Qualitative in-depth interviews with a cross-sectional time horizon.

Setting
The early COVID-19 pandemic in Sweden, from 1 June through 14 September, 2020.

Participants
A total of 10 patient lead users were recruited from the Swedish patient lead users (spetspatient) network. All participants were living with different long-term conditions and matched the definition of being patient lead users.

Results
We found that during the early pandemic, patient lead users experienced that they no longer knew how to best manage their own health and care situations. On an individual level, they described an initial lack of knowledge, new routines, including a change in their health and an experience of people without a disease being in the same situation as them, for a while. On a systemic level, they described a fear of imminent unmet-care backlogs and decreased opportunities for sharing patient perspectives in care organisation, but also described increased networking.

Conclusions
Patient lead users can be seen as an emerging community of practice, and as such could be a valuable resource as a complementary communication channel for an improved health system. The health systems were not able to fully acknowledge and engage with the resource of patient lead users during the pandemic.

Association between COVID-19 vaccination rates and the Australian 'Million Dollar Vax competition: an observational study

Objective
To examine the association between financial incentives from entry into a vaccine competition with the probability of vaccination for COVID-19.

Design
A cross-sectional study with adjustment for covariates using logistic regression.

Setting
October and November 2021, Australia.

Participants
2375 respondents of the Taking the Pulse of the Nation survey.

Primary and secondary outcome measures
The proportion of respondents who had any vaccination, a first dose only, or second dose after the competition opened.

Results
Those who entered the competition were 2.27 (95% CI 1.73 to 2.99) times more likely to be vaccinated after the competition opened on 1 October than those who did not enter—an increase in the probability of having any dose of 0.16 (95 % CI 0.10 to 0.21) percentage points. This increase was mostly driven by those receiving second doses. Entrants were 2.39 (95% CI 1.80 to 3.17) times more likely to receive their second dose after the competition opened.

Conclusions
Those who entered the Million Dollar Vax competition were more likely to have a vaccination after the competition opened compared with those who did not enter the competition, with this effect dominated by those receiving second doses.

Patients awaiting surgery for neurosurgical diseases during the first wave of the COVID-19 pandemic in Spain: a multicentre cohort study

Objectives
The large number of infected patients requiring mechanical ventilation has led to the postponement of scheduled neurosurgical procedures during the first wave of the COVID-19 pandemic. The aims of this study were to investigate the factors that influence the decision to postpone scheduled neurosurgical procedures and to evaluate the effect of the restriction in scheduled surgery adopted to deal with the first outbreak of the COVID-19 pandemic in Spain on the outcome of patients awaiting surgery.

Design
This was an observational retrospective study.

Settings
A tertiary-level multicentre study of neurosurgery activity between 1 March and 30 June 2020.

Participants
A total of 680 patients awaiting any scheduled neurosurgical procedure were enrolled. 470 patients (69.1%) were awaiting surgery because of spine degenerative disease, 86 patients (12.6%) due to functional disorders, 58 patients (8.5%) due to brain or spine tumours, 25 patients (3.7%) due to cerebrospinal fluid (CSF) disorders and 17 patients (2.5%) due to cerebrovascular disease.

Primary and secondary outcome measures
The primary outcome was mortality due to any reason and any deterioration of the specific neurosurgical condition. Second, we analysed the rate of confirmed SARS-CoV-2 infection.

Results
More than one-quarter of patients experienced clinical or radiological deterioration. The rate of worsening was higher among patients with functional (39.5%) or CSF disorders (40%). Two patients died (0.4%) during the waiting period, both because of a concurrent disease. We performed a multivariate logistic regression analysis to determine independent covariates associated with maintaining the surgical indication. We found that community SARS-CoV-2 incidence (OR=1.011, p

Exploring COVID-19 vaccine uptake, confidence and hesitancy among people experiencing homelessness in Toronto, Canada: protocol for the Ku-gaa-gii pimitizi-win qualitative study

Introduction
People experiencing homelessness are at high risk for COVID-19 and poor outcomes if infected. Vaccination offers protection against serious illness, and people experiencing homelessness have been prioritised in the vaccine roll-out in Toronto, Canada. Yet, current COVID-19 vaccination rates among people experiencing homelessness are lower than the general population. This study aims to characterise reasons for COVID-19 vaccine uptake and hesitancy among people experiencing homelessness, to identify strategies to overcome hesitancy and provide public health decision-makers with information to improve vaccine confidence and uptake in this priority population.

Methods and analysis
The Ku-gaa-gii pimitizi-win qualitative study (formerly the COVENANT study) will recruit up to 40 participants in Toronto who are identified as experiencing homelessness at the time of recruitment. Semistructured interviews with participants will explore general experiences during the COVID-19 pandemic (eg, loss of housing, social connectedness), perceptions of the COVID-19 vaccine, factors shaping vaccine uptake and strategies for supporting enablers, addressing challenges and building vaccine confidence.

Ethics and dissemination
Approval for this study was granted by Unity Health Toronto Research Ethics Board. Findings will be communicated to groups organising vaccination efforts in shelters, community groups and the City of Toronto to construct more targeted interventions that address reasons for vaccine hesitancy among people experiencing homelessness. Key outputs will include a community report, academic publications, presentations at conferences and a Town Hall that will bring together people with lived expertise of homelessness, shelter staff, leading scholars, community experts and public health partners.

Public views of and reactions to the COVID-19 pandemic in England: a qualitative study with diverse ethnicities

Objectives
To explore public reactions to the COVID-19 pandemic across diverse ethnic groups.

Design
Remote qualitative interviews and focus groups in English or Punjabi. Data were transcribed and analysed through inductive thematic analysis.

Setting
England and Wales, June to October 2020.

Participants
100 participants from 19 diverse ‘self-identified’ ethnic groups.

Results
Dismay, frustration and altruism were reported across all ethnic groups during the first 6–9 months of the COVID-19 pandemic. Dismay was caused by participants’ reported individual, family and community risks, and loss of support networks. Frustration was caused by reported lack of recognition of the efforts of ethnic minority groups (EMGs), inaction by government to address COVID-19 and inequalities, rule breaking by government advisors, changing government rules around: border controls, personal protective equipment, social distancing, eating out, and perceived poor communication around COVID-19 and the Public Health England COVID-19 disparities report (leading to reported increased racism and social isolation). Altruism was felt by all, in the resilience of National Health Service (NHS) staff and their communities and families pulling together. Data, participants’ suggested actions and the behaviour change wheel informed suggested interventions and policies to help control COVID-19.

Conclusion
To improve trust and compliance future reports or guidance should clearly explain any stated differences in health outcomes by ethnicity or other risk group, including specific messages for these groups and concrete actions to minimise any risks. Messaging should reflect the uncertainty in data or advice and how guidance may change going forward as new evidence becomes available. A contingency plan is needed to mitigate the impact of COVID-19 across all communities including EMGs, the vulnerable and socially disadvantaged individuals, in preparation for any rise in cases and for future pandemics. Equality across ethnicities for healthcare is essential, and the NHS and local communities will need to be supported to attain this.

Long-term spill-over impact of COVID-19 on health and healthcare of people with non-communicable diseases: a study protocol for a population-based cohort and health economic study

Introduction
The COVID-19 pandemic has a significant spill-over effect on people with non-communicable diseases (NCDs) over the long term, beyond the direct effect of COVID-19 infection. Evaluating changes in health outcomes, health service use and costs can provide evidence to optimise care for people with NCDs during and after the pandemic, and to better prepare outbreak responses in the future.

Methods and analysis
This is a population-based cohort study using electronic health records of the Hong Kong Hospital Authority (HA) CMS, economic modelling and serial cross-sectional surveys on health service use. This study includes people aged ≥18 years who have a documented diagnosis of diabetes mellitus, hypertension, cardiovascular disease, cancer, chronic respiratory disease or chronic kidney disease with at least one attendance at the HA hospital or clinic between 1 January 2010 and 31 December 2019, and without COVID-19 infection. Changes in all-cause mortality, disease-specific outcomes, and health services use rates and costs will be assessed between pre-COVID-19 and-post-COVID-19 pandemic or during each wave using an interrupted time series analysis. The long-term health economic impact of healthcare disruptions during the COVID-19 pandemic will be studied using microsimulation modelling. Multivariable Cox proportional hazards regression and Poisson/negative binomial regression will be used to evaluate the effect of different modes of supplementary care on health outcomes.

Ethics and dissemination
The study was approved by the institutional review board of the University of Hong Kong, the HA Hong Kong West Cluster (reference number UW 21–297). The study findings will be disseminated through peer-reviewed publications and international conferences.

Children in the household and risk of severe COVID-19 during the first three waves of the pandemic: a prospective registry-based cohort study of 1.5 million Swedish men

Objective
To investigate whether Swedish men living with children had elevated risk for severe COVID-19 or infection with SARS-CoV-2 during the first three waves of the pandemic.

Design
Prospective registry-based cohort study.

Participants
1 557 061 Swedish men undergoing military conscription between 1968 and 2005 at a mean age of 18.3 (SD 0.73) years.

Main outcome measures
Infection with SARS-CoV-2 and hospitalisation due to COVID-19 from March 2020 to September 2021.

Results
There was a protective association between preschool children at home and hospitalisation due to COVID-19 during the first and third waves compared with only older or no children at all, with ORs (95% CIs) 0.63 (0.46 to 0.88) and 0.75 (0.68 to 0.94) respectively. No association was observed for living with children 6–12 years old, but for 13–17 years old, the risk increased. Age in 2020 did not explain these associations. Further adjustment for socioeconomic and health factors did not attenuate the results. Exposure to preschool children also had a protective association with testing positive with SARS-CoV-2, with or without hospitalisation, OR=0.91 (95% CI 0.89 to 0.93), while living with children of other ages was associated with increased odds of infection.

Conclusions
Cohabiting with preschool children was associated with reduced risk for severe COVID-19. Living with school-age children between 6 and 12 years had no association with severe COVID-19, but sharing the household with teenagers and young adults was associated with elevated risk. Our results are of special interest since preschools and compulsory schools (age 6–15 years) in Sweden did not close in 2020.

Global monitoring of public interest in preventive measures against COVID-19 via analysis of Google Trends: an infodemiology and infoveillance study

Objectives
The COVID-19 pandemic has influenced people’s concerns regarding infectious diseases and their preventive measures. However, the magnitude of the impact and the difference between countries are unclear. This study aimed to assess the magnitude of the impact of COVID-19 on public interest and people’s behaviours globally in preventing infectious diseases while comparing international trends and sustainability.

Design
An infodemiology and infoveillance study.

Setting
The study employed a web-based data collection to delineate public interest regarding COVID-19 preventive measures using Google Trends.

Primary and secondary outcome measures
A relative search volume was assigned to a keyword, standardising it from 0 to 100, with 100 representing the highest share of the term searches. The search terms “coronavirus”, “wash hand”, “social distancing”, “hand sanitizer” and “mask” were investigated across 196 different countries and regions from July 2018 to October 2021 and weekly reports of the relative search volume were obtained. Persistence of interest was assessed by comparing the first 20 weeks with the last 20 weeks of the study period.

Results
Although the relative search volume of “coronavirus” increased and was sustained at a significantly higher level (p

Risk of adverse events and reported clinical relapse after COVID-19 vaccination in patients with IBD

We have read with interest the recent papers of Kennedy et al1 2 regarding the attenuated anti-SARS-CoV-2 antibody response in patients with IBD and the crucial role of the COVID-19 vaccine in this cohort. The COVID-19 vaccine has been recommended especially for the vulnerable population, including immune-mediated inflammatory diseases.3–5 Therefore, we explored the rate of adverse events (AEs) and the onset of GI symptoms after vaccination with different COVID-19 vaccines in a large cohort of patients with IBD. In this prospective study, we collected data (demographic and clinical variables, COVID-19 vaccine type, local, systemic or allergic AEs, and GI symptoms) from 488 (mean age±SD 55.3±14.4 years, 44.9% male) patients with IBD (UC 50.4%, Crohn’s disease 47.8% and undetermined IBD 1.8%) on regular follow-up at our IBD unit who had been administered COVID-19 vaccination from June to July 2021.

Inequalities in the evolution of the COVID-19 pandemic: an ecological study of inequalities in mortality in the first wave and the effects of the first national lockdown in England

Objectives
To examine how ecological inequalities in COVID-19 mortality rates evolved in England, and whether the first national lockdown impacted them. This analysis aimed to provide evidence for important lessons to inform public health planning to reduce inequalities in any future pandemics.

Design
Longitudinal ecological study.

Setting
307 lower-tier local authorities in England.

Primary outcome measure
Age-standardised COVID-19 mortality rates by local authority, regressed on Index of Multiple Deprivation (IMD) and relevant epidemic dynamics.

Results
Local authorities that started recording COVID-19 deaths earlier were more deprived, and more deprived authorities saw faster increases in their death rates. By 6 April 2020 (week 15, the earliest time that the 23 March lockdown could have begun affecting death rates) the cumulative death rate in local authorities in the two most deprived deciles of IMD was 54% higher than the rate in the two least deprived deciles. By 4 July 2020 (week 27), this gap had narrowed to 29%. Thus, inequalities in mortality rates by decile of deprivation persisted throughout the first wave, but reduced during the lockdown.

Conclusions
This study found significant differences in the dynamics of COVID-19 mortality at the local authority level, resulting in inequalities in cumulative mortality rates during the first wave of the pandemic. The first lockdown in England was fairly strict—and the study found that it particularly benefited those living in more deprived local authorities. Care should be taken to implement lockdowns early enough, in the right places—and at a sufficiently strict level—to maximally benefit all communities, and reduce inequalities.

COCOS trial: COrticosteroids for COVID-19-induced loss of Smell-protocol for a single-centred, double-blind, randomised, placebo-controlled trial

Introduction
Hyposmia and anosmia are common in COVID-19. Most patients regain normal smell within 4 weeks, but severe loss of smell persists roughly in 20% after 2 months and may last up to a year or longer. These persistent smell disorders greatly influence daily life. It is hypothesised that COVID-19 induces inflammation around the olfactory nerve and in the olfactory pathway, leading to smell disorders. Corticosteroids might reduce this local inflammatory response and improve smell.

Methods and analysis
We will conduct a single-centre, randomised, placebo-controlled trial to determine the efficacy of a short high-dose treatment of oral prednisolone for persistent loss of smell after COVID-19 in the early phase. We will include 116 patients with persistent ( >4 weeks) loss of smell within 12 weeks of COVID-19 diagnosis, based on a positive PCR/antigen test. One group receives 40 mg of prednisolone for 10 days and the other group receives matching placebo treatment. In addition, all patients will perform smell training for 12 weeks. The primary outcome is objective olfactory function measured by means of sniffin’ sticks test. Secondary outcomes are objective gustatory function by means of taste strips test and subjective taste and smell ability, trigeminal sensations, quality of life and nasal symptoms, measured by three questionnaires. These outcomes will be measured at inclusion before treatment and 12 weeks later.

Ethics and dissemination
The Institutional Review Board of the University Medical Center Utrecht approved the research protocol (21-635/G-D, October 2021). The trial results will be shared in peer-reviewed medical journals and scientific conferences.

Trial registration number
NL9635. EUCTR2021-004021-71-NL.
