Relationship Between Severity and Length of Exposure to COVID-19 Parameters and Resulting Government Responses and the Suicide Crisis Syndrome (SCS).

OBJECTIVE: The COVID-19 pandemic has had a globally devastating psychosocial impact. A detailed understanding of the mental health implications of this worldwide crisis is critical for successful mitigation of and preparation for future pandemics. Using a large international sample, we investigated in the present study the relationship between multiple COVID-19 parameters (both disease characteristics and government responses) and the incidence of the suicide crisis syndrome (SCS), an acute negative affect state associated with near-term suicidal behavior. METHODS: Data were collected from 5528 adults across 10 different countries in an anonymous web-based survey between June 2020 and January 2021. RESULTS: Individuals scoring above the SCS cut-off lived in countries with higher peak daily cases and deaths during the first wave of the pandemic. Additionally, the longer participants had been exposed to markers of pandemic severity (eg, lockdowns), the more likely they were to screen positive for the SCS. Findings reflected both country-to-country comparisons and individual variation within the pooled sample. CONCLUSION: Both the pandemic itself and the government interventions utilized to contain the spread appear to be associated with suicide risk. Public policy should include efforts to mitigate the mental health impact of current and future global disasters.

Machine learning insights into PM2.5 changes during COVID-19 lockdown: LSTM and RF analysis in Mashhad.

This study seeks to investigate the impact of COVID-19 lockdown measures on air quality in the city of Mashhad employing two strategies. We initiated our research using basic statistical methods such as paired sample t-tests to compare hourly PM2.5 data in two scenarios: before and during quarantine, and pre- and post-lockdown. This initial analysis provided a broad understanding of potential changes in air quality. Notably, a low reduction of 2.40% in PM2.5 was recorded when compared to air quality prior to the lockdown period. This finding highlights the wide range of factors that impact the levels of particulate matter in urban settings, with the transportation sector often being widely recognized as one of the principal causes of this issue. Nevertheless, throughout the period after the quarantine, a remarkable decrease in air quality was observed characterized by distinct seasonal patterns, in contrast to previous years. This finding demonstrates a significant correlation between changes in human mobility patterns and their influence on the air quality of urban areas. It also emphasizes the need to use air pollution modeling as a fundamental tool to evaluate and understand these linkages to support long-term plans for reducing air pollution. To obtain a more quantitative understanding, we then employed cutting-edge machine learning methods, such as random forest and long short-term memory algorithms, to accurately determine the effect of the lockdown on PM2.5 levels. Our models' results demonstrated remarkable efficacy in assessing the pollutant concentration in Mashhad during lockdown measures. The test set yielded an R-squared value of 0.82 for the long short-term memory network model, whereas the random forest model showed a calculated cross-validation R-squared of 0.78. The required computational cost for training the LSTM and the RF models across all data was 25 min and 3 s, respectively. In summary, through the integration of statistical methods and machine learning, this research attempts to provide a comprehensive understanding of the impact of human interventions on air quality dynamics.

Psychosocial risk profiles to address future health emergencies: a country study during the COVID-19 lockdown period in Colombia.

Introduction: The different strategies used worldwide to curb the COVID-19 pandemic between 2020 and 2021 had a negative psychosocial impact, which was disproportionately higher for socially and economically vulnerable groups. This article seeks to identify the psychosocial impact of the confinement period during the COVID-19 pandemic for the Colombian population by identifying profiles that predict the levels of different mental health indicators (feelings of fear, positive emotions or feelings during free time, and work impact) and based on them, characterize the risk factors and protection that allows us to propose guidelines for prevention or recovery from future health emergencies. Methods: This is an observational, cross-sectional, retrospective ex post facto study. Multistage cluster probabilistic sampling and binary logistic regression analysis were used to predict extreme levels of various mental health indicators based on psychosocial indicators of the COVID-19 confinement period and to identify risk and protection factors. Results: A relationship was established between the combination of some of the different psychosocial factors evaluated (this combination being the predictive profile identified) with each of the three main variables: feeling of fear (n = 8,247; R = 0.32; p = 0.00; Poverall = 62.4%; 𝜔overall = 0.25; 1-𝛽overall = 1.00), positive emotions or feelings during free time (n = 6,853; R = 0.25; p = 0.00; Poverall = 59.1%; 𝜔overall = 0.18; 1-𝛽overall = 1.00) and labour impact (n = 4,573; R = 0.47; p = 0.63; Poverall = 70.4%; 𝜔overall = 0.41; 1-𝛽overall = 1.00), with social vulnerability determined by sociodemographic factors that were common in all profiles (sex, age, ethnicity and socioeconomic level) and conditions associated with job insecurity (unemployed, loss of health insurance and significant changes to job's requirements) and place of residence (city). Conclusion: For future health emergencies, it is necessary to (i) mitigate the socio-employment impact from emergency containment measures in a scaled and differentiated manner at the local level, (ii) propose prevention and recovery actions through psychosocial and mental health care accessible to the entire population, especially vulnerable groups, (iii) Design and implement work, educational and recreational adaptation programs that can be integrated into confinement processes.

Effects of COVID-19 on coastal and marine environments: Aggravated microplastic pollution, improved air quality, and future perspective.

The COVID-19 pandemic during 2020-2023 has wrought adverse impacts on coastal and marine environments. This study conducts a comprehensive review of the collateral effects of COVID-19 on these ecosystems through literature review and bibliometric analysis. According to the output and citation analysis of these publications, researchers from the coastal countries in Asia, Europe, and America payed more attentions to this environmental issue than other continents. Specifically, India, China, and USA were the top three countries in the publications, with the proportion of 19.55%, 18.99%, and 12.01%, respectively. The COVID-19 pandemic significantly aggravated the plastic and microplastic pollution in coastal and marine environments by explosive production and unproper management of personal protective equipment (PPE). During the pandemic, the estimated mismanaged PPE waste ranged from 16.50 t/yr in Sweden to 250,371.39 t/yr in Indonesia. In addition, the PPE density ranged from 1.13 × 10-5 item/m2 to 2.79 item/m2 in the coastal regions worldwide, showing significant geographical variations. Besides, the emerging contaminants released from PPE into the coastal and marine environments cannot be neglected. The positive influence was that the COVID-19 lockdown worldwide reduced the release of air pollutants (e.g., fine particulate matter, NO2, CO, and SO2) and improved the air quality. The study also analyzed the relationships between sustainable development goals (SDGs) and the publications and revealed the dynamic changes of SDGs in different periods the COVID-19 pandemic. In conclusion, the air was cleaner due to the lockdown, but the coastal and marine contamination of plastic, microplastic, and emerging contaminants got worse during the COVID-19 pandemic. Last but not least, the study proposed four strategies to deal with the coastal and marine pollution caused by COVID-19, which were regular marine monitoring, performance of risk assessment, effective regulation of plastic wastes, and close international cooperation.

LDA2Net Digging under the surface of COVID-19 scientific literature topics via a network-based approach.

During the COVID-19 pandemic, the scientific literature related to SARS-COV-2 has been growing dramatically. These literary items encompass a varied set of topics, ranging from vaccination to protective equipment efficacy as well as lockdown policy evaluations. As a result, the development of automatic methods that allow an in-depth exploration of this growing literature has become a relevant issue, both to identify the topical trends of COVID-related research and to zoom-in on its sub-themes. This work proposes a novel methodology, called LDA2Net, which combines topic modelling and network analysis, to investigate topics under their surface. More specifically, LDA2Net exploits the frequencies of consecutive words pairs (i.e. bigram) to build those network structures underlying the hidden topics extracted from large volumes of text by Latent Dirichlet Allocation (LDA). Results are promising and suggest that the topic model efficacy is magnified by the network-based representation. In particular, such enrichment is noticeable when it comes to displaying and exploring the topics at different levels of granularity.

[Did entry into nursing home during the health crisis favor the emergence of traumatic symptoms in the elderly?: Entry into nursing home and Covid]. / L'entrée en Ehpad, durant la crise sanitaire, a-t-elle favorisé l'émergence de symptômes traumatiques chez le sujet âgé ?

Our aim is to explore the possible emergence of traumatic symptoms and the identity-related repercussions of the restrictions on elderly, who entered into nursing homes during the Covid-19 health crisis in France. Twenty-five subjects institutionalised before the health crisis and twenty-six subjects institutionalised during the periods of lockdown into nursing homes completed scales assessing anxiety-depressive symptomatology, traumatic symptoms and identity. Anxiety and depression symptoms were similar between the groups. The institutionalised group showed a significantly higher prevalence of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria D and E on the Post traumatic Stress Disorder Checklist version DSM-5 (PCL-5) during lockdown. Entry into an institution during the health crisis would have favored the emergence of traumatic symptoms in the participants. Consideration of the ethical issues raised by this study could make it possible to offer more individualised support to elderly during their transition to a new home.

Heterogeneity of the effect of the COVID-19 pandemic on the incidence of Metabolic Syndrome onset at a Japanese campus.

Background: The coronavirus disease 2019 (COVID-19) outbreak began in China in December 2019, with the World Health Organization declaring a state of emergency in January 2020. Worldwide implementation of lockdown measures to slow the spread of the virus led to reduced physical activity, disrupted eating habits, mental health issues, and sleep disturbances, which increased the risk of lifestyle-related diseases such as metabolic syndrome (MetS). During the COVID-19 pandemic, healthcare workers, especially intensive care workers, experienced longer working hours and burnout, which further increased the risk of lifestyle-related diseases. Accordingly, it is important to identify individuals at a risk of new-onset MetS during a pandemic, which could direct preventive interventions. This study aimed to assess the heterogeneous impact of the COVID-19 pandemic on the incidence of new-onset MetS based on the conditional average treatment effect (CATE) and to identify at-risk populations. Methods: This study analyzed health checkup data obtained from Okayama University Shikata Campus workers using paired baseline and follow-up years. Baseline data encompassed 2017 to 2019, with respective follow-up data from 2018 to 2020. Furthermore, as the COVID-19 pandemic in Japan began in January 2020, workers who underwent follow-up health checkups in 2018 to 2019 and 2020 were considered as "unexposed" and "exposed," respectively. As the Shikata campus has several departments, comparisons among departments were made. The primary outcome was new-onset MetS at follow-up. Predictor variables included baseline health checkup results, sex, age, and department (administrative, research, medical, or intensive care department). X-learner was used to calculate the CATE. Results: This study included 3,572 eligible individuals (unexposed, n = 2,181; exposed, n = 1,391). Among them, 1,544 (70.8%) and 866 (62.3%) participants in the unexposed and exposed groups, respectively, were females. The mean age (±standard deviation) of the unexposed and exposed groups was 48.2 ± 8.2 and 47.8 ± 8.3 years, respectively. The COVID-19 pandemic increased the average probability of new-onset MetS by 4.4% in the overall population. According to the department, the intensive care department showed the highest CATE, with a 15.4% increase. Moreover, there was large heterogeneity according to the department. The high-CATE group was characterized by older age, urinary protein, elevated liver enzymes, higher triglyceride levels, and a history of hyperlipidemia treatment. Conclusions: This study demonstrated that the COVID-19 pandemic increased the incidence of new-onset MetS, with this effect showing heterogeneity at a single Japanese campus. Regarding specific populations, workers in the intensive care department showed an increased risk of new-onset MetS. At-risk populations require specific preventive interventions in case the current COVID-19 pandemic persists or a new pandemic occurs.

Impact of COVID -19 on expanded programme on Immunisation in District Dir lower Khyber Pakhtunkhwa.

Objectives: To study the impact of coronavirus disease-2019 on Expanded Programme on Immunisation in a rural setting. METHODS: The descriptive, cross-sectional study was conducted in five union councils of District Dir Lower, in the Khyber Pakhtunkhwa province of Pakistan. Data was collected from March to August 2020, which was a period of lockdowns in the wake of the coronavirus disease-2019, and then from March to August 2021. The sample comprised children aged <2 years. Data was analysed using SPSS 25. RESULTS: Of the 330 children, 210(63.6%) were boys, and 120(36.4%) were girls, and all 330(100%) were located in rural areas. First-phase data showed that the maximum coverage rate of immunisation was 258(78.2%) noted in OPV1(Oral Polio Vaccine) Penta1(Pentavalent vaccine), PCV10-1 (Pneumococcal pneumonia) and Rota 1(Rota Vaccine), and the least vaccination rate was 68.2% for Measle-1. In the second phase, 23% incline was noted in Measles-2 vaccination, followed by 16.3% in OPV2, Penta 2, PCV10-2 and Rota 2, 16% in Measles-1, 14% in OPV-3, Penta-3, PCV10-3, Rota-3 and IPV, 11.5% in OPV-1, Penta-1, PCV10-1, and Rota-1, and 10.6% in OPV-0 and BCG-0. CONCLUSIONS: Immunisation programme was affected by lockdowns during the active phase of the coronavirus disease-2019 pandemic.

Changes in diet and physical activity in students during lockdown by example of COVID-19 pandemic.

Background: Due to the spread of COVID-19 infections around the world, in early 2020, the World Health Organization (WHO) announced a global pandemic, i.e. an epidemic of particularly large dimensions affecting countries and entire continents. Long-term stay at home and self-isolation may have significantly impacted lifestyle, diet, food choices and access to food, as well as physical activity in the entire population, including students. Objective: The aim of the study was to examine the impact of social isolation caused by the coronavirus pandemic on changes in diet, lifestyle and body mass index in a group of students, so that we would be better prepared for future new viral infections with characteristics similar to Covid-19. Material and Methods: The study was conducted in 2021 using a cross-sectional online survey (using the CAWI technique). The survey was addressed to students of universities in Poland who were over 18 years of age. After excluding forms completed incorrectly or with incorrect data, the final analysis of the results included the responses of 196 respondents. Statistical analyzes were performed in STATISTICA 13.3. Statistical significance was assumed at the level of p ≤ 0.05. Results: The study involved 136 women and 60 men with an average age of 23. The majority of respondents were residents of cities with over 500,000 inhabitants (50%), were students of 1st degree (45%) in medical/natural sciences (36%). The largest percentage of respondents (above 70%), before the pandemic and during isolation, had normal body weight, according to the BMI. There were significant statistical differences between gender and changes during COVID-19 pandemic in sleeping (p=0.013), physical activity (p=0.028), as well as the consumption of tea (p=0.047), milk and dairy products (p=0.041), alcohol (p=0.001) and red meat (p=0.003), vegetables (p=0.049), sweets (p=0.029) and fast food (p=0.004). Conclusions: Due to the fact that the impact of the coronavirus pandemic on the diet and lifestyle has been demonstrated, it is very important that the recommendations of public health organizations spread the message about rational nutrition and physical activity in the event of new viral infections among young people, including students.

Mixed effects modelling of excess mortality and COVID-19 lockdowns in Thailand.

Accurate mortality data are critical for understanding the impact of COVID-19 and learning lessons from crisis responses. But published statistics risk misrepresenting deaths due to limited testing, underreporting, and lack of subnational data, especially in developing countries. Thailand experienced four COVID-19 waves between January 2020 and December 2021, and used a color-coded, province-level system for lockdowns. To account for deaths directly and indirectly caused by COVID-19, this paper uses mixed effects modelling to estimate counterfactual deaths for 2020-2021 and construct a monthly time series of provincial excess mortality. A fixed effects negative binomial and mixed effects Poisson model both substantiate other studies' estimates of excess deaths using subnational data for the first time. Then, panel regression methods are used to characterize the correlations among restrictions, mobility, and excess mortality. The regressions show that mobility reductions modestly curbed mortality immediately upon imposition, suggesting that aversion of non-COVID deaths was a major aspect of the lockdowns' effect in Thailand. However, the estimates are imprecise. An auto-regressive distributed lag model suggests that the effect of lockdowns was through reduced mobility, but the effectiveness appears to have varied over the course of the pandemic.

Perceptions regarding second wave of coronavirus disease 2019 (COVID-19) pandemic among Indian adults: A cross-sectional study.

BACKGROUND AND AIMS: A massive surge in coronavirus disease 2019 (COVID-19) cases and deaths occurred in India during March-April 2021, and this was considered as second wave of the pandemic in the country. This study was conducted to find out the perceptions about second wave of the COVID-19 pandemic among Indian adults. METHODS: An online-survey-based cross-sectional study was conducted over 3 weeks from April 21, 2021 to May 11, 2021. Information regarding sociodemographic profile, perceptions about COVID-19 during second wave, perceptions and practices related to COVID-19 vaccination, COVID-19 appropriate behavior, and government's response to the pandemic was collected. Descriptive analysis was performed. RESULTS: A total of 408 study participants were included. Mean age of the study participants was 29.2 ± 10.4 years. Around 92.6 percent (378) of respondents agreed that COVID-19 in 2021 is different from 2020. Perceived reasons for increased severity and cases were change in virus characteristics; social, religious, and political gatherings; and complacent behavior by people. Three-fourth (311, 76.2 percent) of the study participants agreed that vaccines have a positive role against COVID-19. Majority of the study participants (329, 80.6 percent) concurred that lockdown restrictions help in control of the pandemic. About 60.3 percent (246) of respondents had less trust on government post this pandemic compared to pre-COVID-19 times. CONCLUSION: The public perception about reasons for second wave in India acknowledges both human and virus factors and highlights the importance of shared responsibility between citizens and government for controlling the pandemic.

The evolution of household forgone essential care and its determinants during the COVID-19 pandemic in Nigeria: A longitudinal analysis.

Apart from the morbidity and mortality, the Coronavirus disease 2019 (COVID-19) pandemic has increased the predisposition of households in Nigeria to forgone care, thereby increasing their vulnerability to adverse health consequences. Since there is no previous study in Nigeria on the evolution of pandemic-related forgone care and its drivers, our study assess the evolution of the problem using descriptive and nationally representative panel data analyses. We found about a 30% prevalence of forgone care during the lockdown, which declined progressively afterwards, dropping by 69.50 percentage points between April 2020 and April 2022. This decline produced a surge in households needing care from about 35.00% in the early pandemic to greater than 50%, beginning in early 2021. The forgone care was primarily due to financial hindrances, movement restrictions, and supply-side disruptions. Household socioeconomic factors such as income loss had 2.74 [95%CI: 1.45-5.17] times higher odds of forgone care, job loss, food insecurity, and poverty were 87% (OR: 1.87 [95%CI: 1.25-2.79]), 60% (OR: 1.60 [95%CI: 1.12-2.31]) and 76% (OR: 1.76 [95%CI: 1.12-2.75]) more likely to predispose households to forgone care, respectively. Also, geographical location, such as the South-South zone, induced 1.98 [95%CI: 1.09-3.58] times higher odds of forgone care than North-Central. A married female household head increased the odds by 6.07 [95%CI: 1.72-21.47] times compared with an unmarried female head. However, having a married household head, social assistance, and North-East or North-West zone compared with North-Central increased the chance of accessing care by 69% (OR 0.31 [95%CI: 0.16-0.59]), 59%,(OR 0.41 [95%CI: 0.21-0.77]), 72% (OR 0.28 [95%CI: 0.15-0.53]) and 64% (OR 0.36 [95%CI: 0.20-0.65]), respectively. Non-communicable diseases, disability, old age, large household size and rural-urban location did not affect the forgone care. Our study highlights the need to strengthen Nigeria's health system, create policies to promote healthcare accessibility and prepare the country for future pandemic challenges.

Health workforce incentives and dis-incentives during the COVID-19 pandemic: experiences from Democratic Republic of Congo, Nigeria, Senegal, and Uganda.

BACKGROUND: The COVID-19 pandemic presented a myriad of challenges for the health workforce around the world due to its escalating demand on service delivery. A motivated health workforce is critical to effectual emergency response and in some settings, incentivizing health workers motivates them and ensures continuity in the provision of health services. We describe health workforce experiences with incentives and dis-incentives during the COVID-19 response in the Democratic Republic of Congo (DRC), Senegal, Nigeria, and Uganda. METHODS: This is a multi-country qualitative research study involving four African countries namely: DRC, Nigeria, Senegal, and Uganda which assessed the workplace incentives instituted in response to the COVID-19 pandemic. Key informant interviews (n = 60) were conducted with staff at ministries of health, policy makers and health workers. Interviews were virtual using the telephone or Zoom. They were audio recorded, transcribed verbatim, and analyzed thematically. Themes were identified and quotes were used to support findings. RESULTS: Health worker incentives included (i) financial rewards in the form of allowances and salary increments. These motivated health workers, sustaining the health system and the health workers' efforts during the COVID-19 response across the four countries. (ii) Non-financial incentives related to COVID-19 management such as provision of medicines/supplies, on the job trainings, medical care for health workers, social welfare including meals, transportation and housing, recognition, health insurance, psychosocial support, and supervision. Improvised determination and distribution of both financial and non-financial incentives were common across the countries. Dis-incentives included the lack of personal protective equipment, lack of transportation to health facilities during lockdown, long working hours, harassment by security forces and perceived unfairness in access to and inadequacy of financial incentives. CONCLUSION: Although important for worker motivation, financial and non-financial incentives generated some dis-incentives because of the perceived unfairness in their provision. Financial and non-financial incentives deployed during health emergencies should preferably be pre-determined, equitably and transparently provided because when arbitrarily applied, these same financial and non-financial incentives can potentially become dis-incentives. Moreover, financial incentives are useful only as far as they are administered together with non-financial incentives such as supportive and well-resourced work environments. The potential negative impacts of interventions such as service delivery re-organization and lockdown within already weakened systems need to be anticipated and due precautions exercised to reduce dis-incentives during emergencies.

Orthodontists' use of remote monitoring platforms pre-, amid, and post-COVID-19: a survey study.

BACKGROUND: Did the COVID-19 pandemic affect orthodontists' use of remote monitoring platforms? The goal of this research was to examine orthodontists' experiences implementing remote monitoring platforms before, during, and after the initial COVID-19 lockdown. METHODS: In this descriptive cross-sectional survey study, an electronic, anonymous questionnaire consisting of a series of 31 short-answer and multiple-choice questions was administered to an international sampling of practicing orthodontists. The target population in the study included currently practicing orthodontists who were graduates of an accredited orthodontic residency program. Participants were recruited in 2021 through collaboration with the American Association of Orthodontists (AAO) Partners in Research Program and the Harvard School of Dental Medicine Orthodontic Alumni Association. Descriptive analysis was conducted, reporting frequency (N and %) distributions for each question. The questionnaire aimed to describe whether orthodontists incorporated remote monitoring platforms into their practices, their experiences doing so, and if the COVID-19 pandemic influenced their use of these resources. RESULTS: Orthodontists' use of remote monitoring platforms was negligible prior to the pandemic; however, a quarter of surveyed orthodontists began using a remote monitoring platform during COVID-19 and nearly all respondents plan to continue using remote monitoring for the foreseeable future. Approximately half of orthodontists believe most patients' treatment progress can be monitored to the standard of care between in-person orthodontic appointments using remote monitoring platforms. Half of the orthodontists who do not currently use a remote monitoring platform in their practice are interested in learning more about how to implement one. CONCLUSIONS: The COVID-19 pandemic led to an increase in the interest and adoption of remote monitoring platforms in orthodontic practices. Most orthodontists had not incorporated remote monitoring platforms into their practices prior to the COVID-19 pandemic. However, this study revealed that a subset of orthodontists utilized the pandemic as motivation to incorporate remote monitoring into their practices and an additional group of orthodontists were interested in incorporating one in the future. Remote monitoring platforms garnered interest and importance with the arrival of the COVID-19 pandemic and may only have an increasing role in the field in years to come.

Training strategies of 10,074 athletes from 121 countries based on human development index in early COVID-19 lockdown.

The aim of this study was to investigate relationships between changes in training practices and human development index (HDI) levels, and identify strategies employed by athletes who consistently maintained their training quantity during the first 100 days of the COVID-19 pandemic. A total of 10,074 athletes (5290 amateur and 4787 professional athletes from 121 countries) completed an online survey between 17 May to 5 July 2020. We explored their training practices, including specific questions on training frequency, duration and quantity before and during lockdown (March-June 2020), stratified according to the human development index (HDI): low-medium, high, or very high HDI. During the COVID-19 lockdown, athletes in low-medium HDI countries focused on innovative training. Nevertheless, women and amateur athletes experienced a substantial reduction in training activity. Performance-driven athletes and athletes from higher HDI indexed countries, were likely to have more opportunities to diversify training activities during lockdowns, facilitated by the flexibility to perform training away from home. Factors such as lockdown rules, socioeconomic environment, and training education limited training diversification and approaches, particularly in low-medium and high HDI countries. Athletes (amateurs and professionals) who maintained the quantity of training during lockdown appeared to prioritize basic cardiovascular and strength training, irrespective of HDI level. Modifying training and fitness programs may help mitigate the decrease in training activities during lockdowns. Customized training prescriptions based on gender, performance, and HDI level will assist individuals to effectively perform and maintain training activities during lockdowns, or other challenging (lockdown-like) situations.

A longitudinal cohort study on the use of health and care services by older adults living at home with/without dementia before and during the COVID-19 pandemic: the HUNT study.

BACKGROUND: Older adults and people with dementia were anticipated to be particularly unable to use health and care services during the lockdown period following the COVID-19 pandemic. To better prepare for future pandemics, we aimed to investigate whether the use of health and care services changed during the pandemic and whether those at older ages and/or dementia experienced a higher degree of change than that observed by their counterparts. METHODS: Data from the Norwegian Trøndelag Health Study (HUNT4 70 + , 2017-2019) were linked to two national health registries that have individual-level data on the use of primary and specialist health and care services. A multilevel mixed-effects linear regression model was used to calculate changes in the use of services from 18 months before the lockdown, (12 March 2020) to 18 months after the lockdown. RESULTS: The study sample included 10,607 participants, 54% were women and 11% had dementia. The mean age was 76 years (SD: 5.7, range: 68-102 years). A decrease in primary health and care service use, except for contact with general practitioners (GPs), was observed during the lockdown period for people with dementia (p < 0.001) and those aged ≥ 80 years without dementia (p = 0.006), compared to the 6-month period before the lockdown. The use of specialist health services decreased during the lockdown period for all groups (p ≤ 0.011), except for those aged < 80 years with dementia. Service use reached levels comparable to pre-pandemic data within one year after the lockdown. CONCLUSION: Older adults experienced an immediate reduction in the use of health and care services, other than GP contacts, during the first wave of the COVID-19 pandemic. Within primary care services, people with dementia demonstrated a more pronounced reduction than that observed in people without dementia; otherwise, the variations related to age and dementia status were small. Both groups returned to services levels similar to those during the pre-pandemic period within one year after the lockdown. The increase in GP contacts may indicate a need to reallocate resources to primary health services during future pandemics. TRIAL REGISTRATION: The study is registered at ClinicalTrials.gov, with the identification number NCT04792086.

Perceptions of risk and coping strategies during the COVID-19 pandemic among women and older adults.

The world's health, economic, and social systems have been adversely impacted by the COVID-19 pandemic. With lockdown measures being a common response strategy in most countries, many individuals were faced with financial and mental health challenges. The current study explored the effect of the COVID-19 pandemic on the psychological well-being, perception of risk factors and coping strategies of two vulnerable groups in Malaysia, namely women and older adults from low-income households (USD592). A purposive sample of 30 women and 30 older adults was interviewed via telephone during Malaysia's Movement Control Order (MCO) regarding the challenges they faced throughout the pandemic. Thematic analysis was subsequently conducted to identify key themes. The themes identified from the thematic analysis indicated a degree of overlap between both groups. For women, seven themes emerged: 1) Psychological challenges due to COVID-19 pandemic, 2) Family violence, 3) Finance and employment related stress and anxiety, 4) Women's inequality and prejudice, 5) Coping strategies, 6) Professional support, and 7) Women's empowerment. Similarly, there were six themes for the older adults: 1) Adverse emotional experiences from COVID-19, 2) Threats to health security, 3) Loss of social connections, 4) Government aid to improve older adults' psychological well-being, 5) Psychological support from family members and pets, and 6) Self-reliance, religion, and spirituality. The findings provide valuable information on the specific burdens faced by these groups, and support psychological interventions and mitigations that would be appropriate to improve well-being during the recovery phase.

Non-fatal suicide behaviours across phases in the COVID-19 pandemic: a population-based study in a Catalan cohort.

BACKGROUND: The COVID-19 pandemic has been extensively discussed in the context of its effect on mental health. Although global suicide rates have remained stable during the pandemic, the specific effect on non-fatal suicide behaviours during and after the pandemic remains underexplored. This study aims to investigate patterns of non-fatal suicide behaviours before, during, and after the pandemic. METHODS: In this cohort study, we used data from all hospitals in Catalonia, Spain, collected through the Catalan Suicide Risk Code, which is a specifically designed suicide attempt surveillance protocol, involving a face-to-face, in-depth psychiatric evaluation, after a Catalan resident presents any suicide risk behaviour in any public health-care setting. This evaluation centralises data from suicide registries across the territory. We included non-fatal suicide behaviours, meaning suicidal ideation or attempts that did not result in death, and excluded self-harm behaviours not judged to be linked with suicidal ideation. We considered three periods: the pre-confinement period (Jan 1, 2018, to the enforcement of the lockdown in Spain on March 14, 2020); the confinement period (March 14, 2020, to the end of lockdown on June 21, 2020); and the post-confinement period (June 21, 2020, to Dec 31, 2022). We used Bayesian structural time series models to assess the effect of pandemic phases on non-fatal suicide behaviours, and we ran stratified analyses by sex and age to identify distinct patterns among demographic cohorts. FINDINGS: We obtained 26 482 records from Jan 1, 2018, to Dec 31, 2022. The mean age was 37·94 years (SD 18·07), and the sample included 17 584 (66·4%) women and 8898 (33·6%) men. Data on ethnicity were not collected. Temporal trends showed a mild increase in non-fatal suicide behaviours from Jan 1, 2018, to March 13, 2020; a reduction during the confinement period; and a subsequent rise after confinement. Bayesian models suggested a significant causal effect of lockdown easing, resulting in a 50·77% increase in non-fatal suicide behaviours (95% credible interval [CrI] 26·62-76·58; p<0·0001). Stratified analyses indicated that the easing of lockdown resulted in a significant increase in non-fatal suicide behaviours among women (25·92%; 6·71-44·72; p=0·011) and among individuals aged 18 years and younger (72·75%; 38·81-108·11; p<0·0001). INTERPRETATION: This study provides a comprehensive examination of non-fatal suicide behaviours in Catalonia, Spain, emphasising the dynamics of different COVID-19 pandemic phases. The initial reduction during strict lockdown aligns with Joiner's Interpersonal Theory of Suicide, whereas the post-confinement rise reflects complex factors, including social isolation and economic challenges. Sex-specific and age-specific analyses underscore distinct vulnerabilities, emphasising the need for targeted preventive strategies.

Sociocultural adjustment and social support as predictors for international medical sciences students' anxiety during COVID-19.

BACKGROUND: The prevalence of anxiety is high among international medical sciences students and it increased even more during the COVID-19 pandemic due to different restrictions and social isolation. Successful sociocultural adjustment and social support could be important factors in overcoming those challenges, however, there is a lack of studies which would investigate the role of those factors among inter- national medical students. This study aimed to assess the role of sociocultural adjustment and social support as predictors for international medical students' anxiety during COVID-19. METHODS: Two measurements were conducted via self-reported questionnaires which consisted of three scales - SCAS, MSPSS and GAD-7. In total, 82 international medical students participated in both measurements in this longitudinal study. RESULTS: The findings indicated that 37% of international students had symptoms of moderate or severe anxiety during their first year of studies at university. In the second year, during the COVID-19 pandemic and an official lockdown, 35% of international students had symptoms of moderate or severe anxiety. In addition, this study showed that gender and sociocultural adjustment did not play a role as predictors of students' anxiety during the second year of studies. However, this study revealed that social support provided by family during the first year of studies, as well as having friends or family members who had been ill with COVID-19 predicted higher levels of anxiety at second measurement, while sociocultural adjustment was an even stronger predictor of anxiety in the second year of studies of international medical students. CONCLUSIONS: This knowledge can help to better understand how international medical students felt during the COVID-19 pandemic and what role the above- mentioned factors played in the students' anxiety. As the anxiety level is quite high among international medical students, universities and mental health service providers should take it into consideration and help them to overcome those challenges.
