The COVID-19 pandemic disrupted daily social interactions, potentially affecting mental health. Understanding the risk of depressive and anxiety symptoms is essential for guiding mental health strategies during future crises.

To explore how social networks influenced mental health outcomes during the pandemic and how these relationships changed over time.

Data from the Omtanke2020 study, a prospective cohort study of Swedish adults, were analysed using structural equation modelling (N = 10 918). Surveys at baseline and follow-up at 6 and 12 months assessed social networks, including structural components (e.g. relationship status, frequency of social contact) and perceived components (e.g. emotional support from family, feeling safe at home). Cross-lagged panel modelling was used to observe changes over time in the associations between social network indicators and depressive and anxiety symptoms.

Stronger perceived social support – specifically closeness to family, perceived warmth or love from others and increased societal cohesion – were negatively correlated with depressive and anxiety symptoms across all time points (β coefficients = −0.14 to −0.23, all P < 0.001). Social network variables consistently predicted mental health outcomes, with effect sizes remaining relatively stable over time (β coefficient = −0.17 at baseline, β coefficient = −0.21 at 1-year follow-up).

This study highlights the protective role of the social network – namely perceived social support – in combatting depressive and anxiety symptoms during the COVID-19 pandemic. Interventions that strengthen close interpersonal ties and community cohesion may help mitigate mental health impacts during future public health crises.

To compare and analyze COVID-19 control outcomes, including case severity, vaccination, and excess mortality, across 6 nations (USA, UK, China, Russia, Japan, and South Africa) from January 2020 to December 2022.

This study utilized data from the “Our World in Data” dataset to characterize the epidemiological features of COVID-19 across 6 countries. Generalized linear models (GLMs) were employed to examine the associations between Stringency Index (SI), vaccination coverage, and epidemiological outcomes.

The USA had the highest median cases per million and the UK the highest deaths per million, while China reported the lowest for both. Hospitalization and ICU rates were highest in the UK and the USA, respectively, and lowest in Japan. Vaccination coverage was highest in China and lowest in South Africa. Excess mortality was highest in Russia and lowest in Japan. Generalized linear models indicated a negative association between the SI and cases in China (β = −40, P = 0.015), which became stronger after adjusting for vaccination (β = −311, P < 0.001), but positive associations were observed in the USA, UK, and South Africa. SI was negatively associated with excess mortality in most countries.

Effective pandemic control is highly context-dependent. The relationships among vaccination, variant prevalence, and health care burden were complex, shaped by implementation context, public compliance, and health care capacity.

Although extensive research has been conducted on the impact of the COVID-19 pandemic on global mental health, a systematic synthesis of the cross-time dynamics of suicidal ideation (SI) remains lacking. This study aims to systematically synthesise the global aggregated prevalence of SI before and after the pandemic, investigate the potential association between pandemic exposure and the SI risk through meta-regression analysis of longitudinal studies, and explore key moderating factors.

A systematic search was conducted in Web of Science, PubMed, PsycINFO and ProQuest databases up to August 2025. Observational studies were included if they employed cross-sectional or longitudinal designs and reported the prevalence of SI before and after the pandemic across global regions.

The analysis included 354 cross-sectional studies (N = 8,247,875) and 27 longitudinal studies. In cross-sectional studies, the pooled prevalence of SI was 13.20% [95% CI 12.06%–14.42%]. Pre-pandemic prevalence was 12.52% [95% CI 8.46%–18.14%], and post-pandemic prevalence was 13.24% [95% CI 12.07%–14.50%], with no significant difference. Meta-regression analysis identified three moderators. Specifically, larger sample sizes (n) were associated with lower prevalence (β = −0.232, P < 0.0001); higher study quality predicted lower prevalence (β = −0.278, P < 0.001); and studies on adults reported significantly lower prevalence than adolescents (β = −0.366, P < 0.05). Conversely, time progression during the pandemic, development level, geographical area, gender and measurement method did not show significant independent effects. Interaction analyses also found no significant moderating effect of economic development level or geographical area on the temporal trend of SI prevalence. Longitudinal analysis found no significant increase in prevalence from the pre-pandemic to the post-pandemic period (P = 0.101). However, a small but significant increase occurred between early and late stages within the pandemic (β = 0.265, P = 0.021). Subgroup analyses showed no significant moderation of these temporal changes.

The COVID-19 pandemic’s impact on SI was dynamic. While no significant prevalence change was found between pre- and post-pandemic periods, a significant increase occurred as the crisis progressed. This deteriorating trend was more pronounced in adolescents, identifying them as a key vulnerable group. Methodologically, findings were moderated by the measurement instrument, study quality and sample size, with evidence suggesting potential small-study effects. These findings underscore the need for robust mental health surveillance and targeted interventions for at-risk populations during prolonged public health crises.

The protocol was registered on PROSPERO (CRD42024603151).

This study aimed to assess the prevalence of post-COVID syndrome (PCS) and identify associated risk factors among healthcare workers (HCWs) in a large tertiary care hospital, with the objective of highlighting the importance of preparedness for similar post-viral syndromes in future pandemics.

Post-COVID syndrome, a form of post-viral syndrome, encompasses a range of long-term symptoms affecting multiple organ systems, which can persist after the recovery from COVID-19.

A cross-sectional study was conducted using an online self-administered survey among HCWs who tested positive for COVID-19 at a large tertiary medical centre in Beirut.

Among the 134 participants who had experienced COVID-19, nearly half (47.7%) reported symptoms consistent with PCS. Fatigue, shortness of breath, poor memory, and poor concentration were the most frequently reported symptoms, lasting for over three months post-COVID-19 infection in the majority of patients. Direct care of COVID-19 patients and higher severity of acute COVID-19 infection were significantly associated with an increased likelihood of developing PCS. Further research to enhance understanding and management of post-viral syndromes is needed. Additionally, proactive strategies should be implemented to mitigate associated risks in healthcare settings, emphasizing the importance of preparedness for future pandemics.

The COVID-19 pandemic significantly impacted Saskatchewan, resulting in high per capita case counts and COVID-19-related deaths. While vaccination mandates have been a key strategy to control the pandemic, their impact in Saskatchewan remains poorly documented. This study assessed the effect of COVID-19 vaccine mandates on the incidence of COVID-19 cases and deaths in Saskatchewan during the first year following vaccine rollout.

A single-group interrupted time series analysis with multiple intervention points was conducted using aggregated daily COVID-19 incidence and mortality rates as outcome variables. The models accounted for confounding effects of daily total vaccine doses administered and public health countermeasures, including the stringency index and economic support index, from April 1, 2020 to January 20, 2022. Average daily COVID-19 incidence and mortality rates were estimated for the pre-vaccine rollout period (April 1 to December 14, 2020), and the post-rollout period (December 15, 2020 to January 20, 2022). In addition, nine supplementary initiatives were introduced during the implementation phase. All estimated effects reflected cumulative changes in trend relative to the pre-vaccination period.

Cumulatively, COVID-19 incidence increased faster than the pre-vaccination trend, likely driven by successive variant surges from wild-type to Omicron, while COVID-19–related deaths remained stable across the same period. The implementation of vaccine rollout, prioritization of vaccines for high-risk populations, and proof-of-vaccination policy were effective in reducing daily COVID-19 incidence and deaths in Saskatchewan. Economic support and an increased number of daily vaccine doses administered were also associated with an improved provincial COVID-19 response. Conversely, surges in COVID-19 incidence and deaths occurred following the introduction of the centralized virtual booking system and booster doses. These surges may reflect accessibility challenges, increased testing, emergence of immune-escape variants, relaxation of public health measures before achieving herd immunity, and waning immunity over time.

Economic support, policy measures, and vaccination efforts played important roles in managing public health crises, hence the need for an integrated approach to managing public health crises. However, temporary surges following certain interventions underscore the need for accessible, adaptable strategies that account for variant emergence, immunity waning and public adherence.

We aimed to investigate the effects of the COVID-19 pandemic on the education and professional development, working conditions, and wellbeing of early career psychiatrists (ECPs) in Europe, as well as their attitudes to telepsychiatry.

A questionnaire comprising 24 items was designed by the Early Career Psychiatrists Committee of the European Psychiatric Association. Data were collected online from June 2020 to September 2021. A series of multiple regression analyses were conducted to determine variables that could predict the dependent variables.

Data were obtained from 517 early career psychiatrists from 39 different countries. Men were more confident than women in their knowledge of COVID-19 symptoms and management, including in managing patients with a comorbidity of COVID-19 and a mental disorder. Providing specific recommendations during the COVID-19 pandemic, access to additional educational activities for ECPs, following COVID-19-related recommendations and access to protective equipment were the significant predictors of a higher confidence in managing patients with comorbidity of COVID-19 and mental disorders. The obligation to change the place of work predicted a decreased satisfaction with telepsychiatry as well as a decreased willingness to use telepsychiatry after the COVID-19 pandemic, while a diagnosis of COVID-19, having recommendations for telepsychiatry and access to dedicated platform for telemedicine were predictors of an increased satisfaction with telepsychiatry.

The COVID-19 pandemic has affected ECPs in Europe to varying degrees. The results point to areas where decision-makers can improve the working conditions for ECPs.
