Risultati per: Long COVID: principali risultati, meccanismi e raccomandazioni

Background
COVID-19 disease results in disparate responses between individuals and has led to the emergence of long coronavirus disease (Long-COVID), characterised by persistent and cyclical symptomology. To understand the complexity of Long-COVID, the importance of symptom surveillance and prospective longitudinal studies is evident.

Methods
A 9-month longitudinal prospective cohort study was conducted within Scotland (n=287), using a mobile app to determine the proportion of recovered individuals and those with persistent symptoms and common symptoms, and associations with gender and age.

Results
3.1% of participants experienced symptoms at month 9, meeting the criteria for Long-COVID, as defined by the National Institute for Health and Care Excellence terminology. The random effects model revealed a significant time (month) effect for infection recovery (p

New research suggests SARS-CoV-2 infection may increase the long-term risk of autoimmune or autoinflammatory connective tissue disorders.

Receiving COVID-19 and influenza vaccines at the same time should generate a similar reaction as receiving them separately.

Objectives
This study aimed to explore the perceptions of donation coordinators in Canada and understand how the COVID-19 pandemic impacted their work activities.

Design
A sequential mixed-method design incorporating a cross-sectional survey investigating demographic data, substance use and abuse and perceived stress related to the pandemic and semistructured qualitative interviews to further investigate those.

Setting
Organ donation organisations across Canada.

Participants
Canadian organ and tissue donation coordinators working within deceased donation programmes. Participants were recruited using a purposive sampling technique for the survey and qualitative interviews. Recruitment and data collection took place between January 2022 and March 2023.

Analysis
The data were analysed using descriptive statistics for the quantitative findings and content analysis for the qualitative data.

Results
Of the 175 available coordinators, 120 participated in the survey, and 39 participated in the qualitative interviews. The great majority were female (n=98; 81.7%), registered nurses (n=117; 97.5%) and on average 42 years old (SD=9.64). The survey result for perceived stress showed that, on average, coordinators did not experience high stress levels during the pandemic. We also identified an increase in the consumption of substances to manage workplace stress near the pandemic’s beginning. The qualitative interviews yielded two main themes (Personal Life Changes and Workplace Adjustments) in which coordinators reported their views on challenges with uncertainties, effects on their personal lives, redeployment, stressors and among others.

Conclusion
Our study’s results provide a comprehensive understanding of the perceptions and experiences of coordinators in Canada during the COVID-19 pandemic. Using a combination of methods, we identified various ways coordinators were affected by the pandemic in their personal and professional lives. These findings highlight the need to support the development of adaptive strategies and promote resilience during crises.

Introduction
The TransEAsome project, funded by the Agence Nationale de la Recherche, aims to evaluate the long-term outcomes of patients with oesophageal atresia (OA) between 13 and 14 years old and establish multiomics profiles using data from the world’s biggest OA registry.

Methods and analysis
TransEAsome is a national multicentre population-based cohort study recruiting participants from all qualified French centres for OA surgery at birth. The primary objective is to assess the prevalence of gastro-oesophageal reflux disease in adolescence among patients with OA, with several secondary objectives including the identification of risk factors and multiomic profiles from oesophageal biopsies and blood samples collected between 13 and 14 years old, compared with a control group. This comprehensive characterisation of phenotype and omic profiles aims to enhance the understanding of disease evolution in patients with OA and inform tailored care management strategies.

Ethics and dissemination
The study, coconstructed with input from patients, parents and research-expert adolescents, has obtained approval from the ethics research committee: Comité de protection des personnes Est II. Findings will be disseminated to various target audiences, including the scientific community, research participants, the patient community, the general public, regulatory authorities and policymakers. Data will be made available in a Findable, Accessible, Interoperable, Reusable format on the France Cohortes platform on study completion.

Trial registration number
NCT05995171:Clinical trial

A meta-analysis reaffirms generally better outcomes with therapeutic than with prophylactic anticoagulation — with some exceptions.

Objective
Many individuals exposed to SARS-CoV-2 experience long-term symptoms as part of a syndrome called post-COVID condition (PCC). Research on PCC is still emerging but is urgently needed to support diagnosis, clinical treatment guidelines and health system resource allocation. In this study, we developed a method to identify PCC cases using administrative health data and report PCC prevalence and predictive factors in Manitoba, Canada.

Design
Cohort study.

Setting
Manitoba, Canada.

Participants
All Manitobans who tested positive for SARS-CoV-2 during population-wide PCR testing from March 2020 to December 2021 (n=66 365) and were subsequently deemed to have PCC based on International Classification of Disease-9/10 diagnostic codes and prescription drug codes (n=11 316). Additional PCC cases were identified using predictive modelling to assess patterns of health service use, including physician visits, emergency department visits and hospitalisation for any reason (n=4155).

Outcomes
We measured PCC prevalence as % PCC cases among Manitobans with positive tests and identified predictive factors associated with PCC by calculating odds ratios with 95% confidence intervals, adjusted for sociodemographic and clinical characteristics (aOR).

Results
Among 66 365 Manitobans with positive tests, we identified 15 471 (23%) as having PCC. Being female (aOR 1.64, 95% CI 1.58 to 1.71), being age 60–79 (aOR 1.33, 95% CI 1.25 to 1.41) or age 80+ (aOR 1.62, 95% CI 1.46 to 1.80), being hospitalised within 14 days of COVID-19 infection (aOR 1.95, 95% CI 1.80 to 2.10) and having a Charlson Comorbidity Index of 1+ (aOR 1.95, 95% CI 1.78 to 2.14) were predictive of PCC. Receiving 1+ doses of the COVID-19 vaccine (one dose, aOR 0.80, 95% CI 0.74 to 0.86; two doses, aOR 0.29, 95% CI 0.22 to 0.31) decreased the odds of PCC.

Conclusions
This data-driven approach expands our understanding of the prevalence and epidemiology of PCC and may be applied in other jurisdictions with population-based data. The study provides additional insights into risk and protective factors for PCC to inform health system planning and service delivery.

Introduction
Long-term care (LTC) residents require extensive assistance with daily activities due to physical and cognitive impairments. Medical treatment for LTC residents, when not aligned with residents’ wishes, can cause discomfort without providing substantial benefits. Predictive models can equip providers with tools to guide treatment recommendations that support person-centred medical decision-making. This study protocol describes the derivation and validation of time-to-event predictive models for (1) permanent loss of independence in physical function, (2) permanent severe cognitive impairment and (3) time alive with complete dependence for those with disability starting from the date of onset.

Methods and analysis
We will use population-based administrative health data from the Institute for Clinical Evaluative Sciences of all LTC residents in Ontario, Canada, to construct the derivation and internal validation cohorts. The external validation cohort will use data from LTC residents in Alberta, Canada. Predictors were identified based on existing literature, patient advisors and expert opinions (clinical and analytical). We identified 50 variables to predict the loss of independence in physical function, 58 variables to predict the loss of independence in cognitive function and 36 variables to predict the time spent in a state of dependence. We will use time-to-event models to predict the time to loss of independence and time spent in the state of disability. Full and reduced models (using a step-down procedure) will be developed for each outcome. Predictive performance will be assessed in both derivation and validation cohorts using overall measures of predictive accuracy, discrimination and calibration. We will create risk groups to present model risk estimates to users as median time-to-event. Risk groups will be externally validated within the Alberta LTC cohort.

Ethics and dissemination
Ethics approval was obtained through the Bruyère Research Institute Ethics Committee. Study findings will be submitted for publication and disseminated at conferences. The predictive algorithm will be available to the general public.

Objectives
COVID-19 vaccine was rolled out for the public in August 2021 in Zamfara state, Northen Nigeria. We determined the factors influencing COVID-19 vaccine acceptance.

Settings
We executed a community-based analytical cross-sectional study during the first 4 months of the second phase of the COVID-19 (Oxford/AstraZeneca) mass vaccination campaign in Zamfara state.

Participants
We used multistage sampling to select 910 household heads.

Outcome measures
We used a semistructured electronic questionnaire to collect data on sociodemographic characteristics, uptake and acceptance of COVID-19 vaccine between 12 October and 20 December 2021. We calculated frequencies, proportions, adjusted ORs and 95% CIs for factors influencing COVID-19 vaccine acceptance using logistic regression.

Results
Our respondents had a median age of 48 years (IQR: 37–55), 78.1% (711) were men, a majority more than 30 years, and only 8.9% (81) had received COVID-19 vaccine. Of the 829 unvaccinated respondents, 10.1% (84) accepted to take the vaccine, the current week of the interview while 12.2% (101) rejected the vaccine. Individuals aged 30 years and older (adjusted OR (aOR)=2.39, 95% CI 1.16 to 4.94, p=0.018), who owned a mobile phone (aOR=25.35, 95% CI 11.23 to 57.23, p

Objectives
This study aims (1) to assess the prevalence of severe fatigue among the general population of Geneva, 2 years into the COVID-19 pandemic and (2) to identify pandemic and non-pandemic factors associated with severe fatigue.

Design
Cross-sectional population-based survey conducted in Spring 2022.

Setting
General adult population of Geneva, Switzerland.

Participants
6870 adult participants, randomly selected from the general population, included in the Specchio-COVID-19 cohort study, were invited to answer an online health survey.

Outcome and cofactor measure
Prevalence of severe fatigue was measured by the Chalder Fatigue Questionnaire with a cut-off score≥4 out of 11. We assessed prevalence ratios of severe fatigue considering sociodemographic factors, health and behavioural characteristics (body mass index, depression, recent diagnosis of chronic disease or allergy, acute health event, smoking status, physical activity and sleep quality) and recent self-reported COVID-19 infections.

Results
A total of 4040 individuals participated (participation rate 59%, 58% were women, mean age 53.2 (SD=14.1 years)). Overall prevalence of severe fatigue was 30.7% (95% CI=29.2%–32.1%). After adjusting for age, sex, educational level and pre-existing comorbidities, the following characteristics were associated with severe fatigue: individuals aged 18–24 years (adjusted prevalence ratio (aPR)=1.39 (1.10–1.76)) and 25–34 years (aPR=1.23 (1.05–1.45)), female sex (aPR=1.28 (1.16–1.41)), depression (aPR=2.78 (2.56–3.01)), occurrence of health events unrelated to COVID-19 (aPR=1.51 (1.38–1.65)) and self-reported COVID-19 infection in the past 12 months (aPR=1.41 (1.28–1.56)). After further adjustment for depression, previous associations were maintained except for young age.

Conclusions
About one-third of the adult general population of Geneva experienced severe fatigue, 2 years into the COVID-19 pandemic. Heightened fatigue among young adults is partly explained by depressive symptoms. Recent COVID-19 infection is substantially associated with severe fatigue, regardless of infection severity or co-occurrence of depressive disorder.

Introduction
The SARS-CoV-2 pandemic has caused global devastations in social, economic and health systems of every nation, but disproportionately of nations in Africa. In addition to its grave effects on the global systems, there is continuation or development of new symptoms among individuals who have contracted the virus, with the potential to further stress the health systems on the continent. Therefore, the aim of this scoping review was to collate and summarise the existing research evidence on the prevalence and health effects of post–COVID-19 conditions in Africa.

Methods and analysis
Five main databases were thoroughly searched from 1 September 2023 to 10 May 2024 for eligible articles based on the pre-established inclusion and exclusion criteria. These databases included PubMed, Central, Scopus, Dimensions AI and JSTOR. A total of 17 papers were included in the review. The protocol for this review is already published in BMJ Open; doi:10.1136/bmjopen-2023-082519.

Results
The prevalence of post–COVID-19 conditions in Africa ranged from 2% to as high as 94.7%. Fatigue, dyspnoea and brain fog were among the commonly reported symptoms of post–COVID-19 conditions. Reduced functional status as well as physical and psychosocial disorders were the main health effects reported by the studies reviewed, but no study yet reported the effects of post–COVID-19 conditions on the health systems in Africa.

Conclusions
There is an evidence of high prevalence of post–COVID-19 conditions in the African setting. However, there is limited evidence of the health effects of the post–COVID-19 conditions on patients and health systems in Africa.

Ethics and dissemination
This scoping review involved analysis of secondary data; therefore, no ethical approval was needed. Dissemination of the result is being done through international journals and may also be presented at available research conferences.

Objectives
Long-acting reversible contraception (LARC) provides continuous pregnancy prevention to women for a period of 3 to 12 years, and it is very safe and effective. The aim of this study was to determine the prevalence, determinants and willingness to use LARC among undergraduate female students attending public and private universities in Ekiti State, Southwest Nigeria

Design
This survey employed a cross-sectional comparative study design.

Setting
Public and private universities in Ekiti State, Southwest Nigeria.

Participants
418 female students in their undergraduate years at public and private universities (208 students in public universities and 210 students in private universities).

Primary and secondary outcomes
A semistructured questionnaire was used to gather data, and analysis was done using IBM SPSS V.25. Prevalence, willingness and determinants of LARC were determined and compared between public and private universities at the level of bivariate analysis using 2. Multivariate regression analysis was used to determine the predictor of LARC use. The statistical significance level was placed at a p value of

Objective
During the COVID-19 pandemic, many parents faced heightened stress, anxiety and depression due to the local and global COVID-19 mitigation measures and lockdowns.

Design
This is a cross-sectional study.

Setting
This study used stratified whole-cluster sampling to randomly select three elementary schools within Ezhou City.

Participants
An online survey was administered to the parents of students in one or two classes in grades 1–6, respectively, of each school. Among them, males account for 30.4% and females account for 69.6%. The inclusion criteria included (1) the parent or legal guardian of a primary school student or a person directly responsible for the child’s education and (2) the ability to operate a computer or smartphone to complete the survey. Only one representative from each family was allowed to participate, and surveys with incomplete data were considered invalid and thus excluded.

Results
A total of 764 participants completed the online survey. Overall, 90.4% of the participants were concerned about their children’s mental health and learning during the pandemic. Additionally, 97.0% were aware of the typical symptoms of COVID-19. Only 48.0% of the participants felt the pandemic negatively impacted their lives. The average psychological status score among parents was 87.79±8.91, with 51.6% showing signs of high psychological distress. Significant differences in psychological status were linked to age, education, professional background, sleep status, personal views on the pandemic’s impact and concern for children’s learning (p
