The global case fatality rate due to COVID-19 in hospitalized elderly patients by sex, year, gross domestic product, and continent: A systematic review, meta-analysis, and meta-regression

Risk of suicide, suicide attempt, and suicidal ideation among people with vitamin D deficiency: a systematic review and meta-analysis

BACKGROUND

Evidence shows that vitamin D affects brain function. Transcription of over 1000 genes is known to be controlled by vitamin D, potentially contributing to the neurotrophic and neuroprotective effects that can influence suicidal behavior. Several investigations with contradicting findings have identified an association between suicidal behaviors (SBs) or depressive symptoms and low vitamin D levels. This meta-analysis aimed to analyze the pooled association between vitamin D deficiency and the risk of suicide, suicide attempt (SA), and suicidal ideation (SI).

METHODS

A systematic search was performed through PubMed, Web of science (ISI), Scopus, Embase, and grey literature up to 10 October 2024. Meta-analysis included observational studies that assessed the association between SBs and vitamin D blood serum level and/or vitamin D deficiency. After screening and quality assessment, meta-analysis and sensitivity analysis using random effects model were carried out to estimate the pooled odds ratios (ORs) for the risk of suicide, SA, and SI. We also calculated pooled standard mean difference (SMD) of vitamin D levels between control subjects and patients with SBs.

RESULTS

A total of 14,095 records were identified. Finally, 13 studies participating 515,406 subjects were included in the meta-analysis after eligibility assessment. Vitamin D deficiency non-significantly increased the risk of suicide, SA, and SI (OR = 1.7; 95% CI: 0.93 - 3.12), (OR = 1.65; 95% CI: 0.98 - 2.80), and (OR = 1.15; 95% CI: 0.94 - 1.41), respectively. However, levels of vitamin D in patients with SBs were significantly lower than in controls without any SBs (SMD = -0.69; 95% CI: -0.89 - -0.49).

CONCLUSION

The results of this meta-analysis indicated that vitamin D levels are lower among patients with SBs. These findings can inform suicide prevention programs, particularly for target groups experiencing significant vitamin D deficiency.

Prevalence of and risk factors for early marriage and the correlations with depressive symptoms in northwest of Iran

PURPOSE

Early marriage (EM), also known as child marriage, is a marriage or union between two people when one or both are under 18. Globally, risk factors for EM and the consequences on depressive symptoms (DSs) have been poorly understood. The current study aimed to investigate risk factors for EM and the correlation between EM and DSs.

METHODS

A total of 402 married people were randomly selected from the general population of Malekan County, Iran, from 2017 to 2018. Depression was assessed in the participants after EM through family physicians' medical records in the community health centers. Data were collected using valid and structured instruments as well as face-to-face interviews. Multiple logistic regression analysis was carried out to estimate the adjusted odds ratios (AOR) and 95% confidence intervals (CIs) for the relationship between EM and DSs.

RESULTS

The overall and sex-based prevalence of EM was 21.64% (n = 87), i.e., 69 (26.5%) in females and 19 (13.4%) in males, respectively. In the regression analysis, the low educational level of EM people (AOR = 4.27: 1.28-14.35), their parental (AOR = 5.53: 2.14-17.22), female sex (AOR = 1.58: 1.07-2.33), and family low income (AOR = 2.74: 1.00-7.84), and being a housewife (AOR = 1.71: 1.22-3.26) were identified as the most reliable predictors of EM. In the final analysis, after adjusting for the potential confounders, EM was associated with an increased risk of DSs (AOR = 1.60: 1.2-2.72).

CONCLUSION

Based on the results, EM is common and associated with DSs in this county. Our study provides preliminary findings to guide future studies, given that this issue has been neglected in previous investigations. Progress in reducing EM and addressing its full set of consequences can occur through political commitment and combining the experiences and voices of people affected by EM.

Evaluation of Neurosurgery Consultations in Hospitalized Geriatric Patients During and After the COVID-19 Pandemic

Background and Objectives: This study aims to evaluate neurosurgery consultations for elderly patients during and following the COVID-19 pandemic. Materials and Methods: This study included patients aged 65 and older who were hospitalized in non-neurosurgery departments at Istinye University Gaziosmanpasa Medical Park Hospital and were referred for neurosurgery consultations between 1 April 2020 and 31 May 2024. Patients in the intensive care unit and emergency department were excluded. The period from 1 April 2020 to 30 April 2022 was defined as the pandemic period, and from 1 May 2022 to 31 May 2024 as the post-pandemic period. Results: A total of 123 patients were included in this study, with 57 from the pandemic period and 66 from the post-pandemic period. The average age during the pandemic period was 73.45 years (range: 65-93), compared to 71.09 years (range: 65-94) in the post-pandemic period. During the pandemic, 26.3% of patients were recommended for physical therapy and rehabilitation, 24.6% were advised to undergo surgery, 19.3% received neurology consultations, and 17.5% received medical treatment. In the post-pandemic period, 37.9% were recommended for surgery, 16.7% for neurology, 13.6% for physical therapy and rehabilitation, and 7.6% for medical treatment. Overall, 56.4% of patients accepted surgery. Conclusions: Despite the high prevalence of comorbidities in geriatric patients, appropriate neurosurgical referrals significantly improve treatment success, enhance quality of life and mobility, and reduce mortality. We therefore recommend earlier and more attentive referrals to neurosurgery for elderly patients with relevant symptoms to facilitate timely and effective interventions.

Risk factors for diarrheal diseases among pilgrims during Arba'een mass gathering: a case-control study

BACKGROUND

A significant portion of the Muslim community participates in the Arba'een pilgrimage, with participant numbers increasing each year. There have been relatively few studies on the health of Arba'een Mass gathering (MG). Researching the prevalence and distribution of diseases among Arba'een pilgrims is essential to recognize any outbreaks and take timely responses to contain them. The current study aimed to identify exposures and risk factors for diarrheal disease in pilgrims who referred to the clinics located in Iraq among the Arba'een MG in 2023.

METHODS

This case-control study randomly selected 200 outpatients (100 cases and 100 controls) who were referred to Iraq clinics. Cases were patients with gastrointestinal symptoms (diarrhea), while controls were randomly selected from unaffected pilgrims at the same time for the cases. The study groups matched for age, and sex. Face-to-face interviews using a reliable field based checklist of the Center for Disease Control and Prevention of Iran's Ministry of Health to collect potential exposures and risk factors for diarrheal disease. Multiple logistic regression was used to estimate the crude and adjusted odds ratio (AOR) for the risk of diarrhea with a 95% confidence interval (CI).

RESULTS

The average age of the participants was 38.6 years. Diarrhea in 100% and fever in 81% were the most common clinical symptoms in patients. Having underlying diseases was not associated with an increased risk of diarrhea disease (P > 0.05). Regarding risk factors for diarrheal, the final analysis after adjusting for potential confounders indicated that consumption of insanitary (unpackaged) drinking water (AOR = 1.95; 95% CI: 1.05-3.6; P = 0.024), inappropriate hand washing (AOR = 3.82; 95% CI: 1.7-8.6; P = 0.001), ritual foods (AOR = 2.56; 95% CI: 1.3-5.2; P = 0.004), and public toilets (AOR = 1.46; 95% CI: 1.04-4.3; P = 0.038) were significantly increased the likelihood of diarrheal disease.

CONCLUSIONS

Contamination of water sources, food, inadequate and poor hand washing were the most common sources of diarrheal diseases among Arba'een pilgrims. The results indicate that the potential occurrence of outbreaks, especially water- and foodborne diseases, threatens participants in the Arba'een MG. It is recommended to provide risk assessment, improve pilgrims' awareness, pre-and post-screening, vaccination, compliance with personal hygiene, improvement of the environment, provision of sanitary water and food sources and hygienic disposal of sewage, laboratory diagnosis to identify the common types of pathogens in Arba'een MG.

Prior Engagement in Physical Activity Correlates with Enhanced Quality of Life Perceptions among Older Adults during COVID-19 Lockdown

BACKGROUND

This longitudinal study aimed to evaluate whether prior engagement in a physical exercise program correlated with enhanced perceptions of quality-of-life components among older adults during the COVID-19 lockdown period.

METHODS

The cohort comprised elderly individuals (aged ≥ 65 years) who had previously partaken in a 12-week randomized controlled trial investigating the effects of a mixed aerobic-anaerobic, moderate-intensity exercise program. Participants' health-related quality of life was assessed using the Short Form Health Survey-12 item (SF-12) at the beginning of the initial trial and, again, one year later during the COVID-19 lockdown. In the exercise group, 44 participants were included, while the control group consisted of 49 participants, with computer-based, double-blind randomization conducted in Cagliari, Italy. The differences in scores for each SF-12 item between the two groups from T0 to T1 were compared using one-way ANOVA with Bonferroni corrections. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 27.

RESULTS

No statistically significant differences were observed on average by age (exercise group vs. control group 72.20 ± 4.78 vs. 72.91 ± 4.77; F = 0.513, p = 0.476). A decrease from T0 to T1 towards a better score on the SF-12 was observed in the exercise group compared to the control group in item 1 (F = 67.463, p < 0.0001); in item 5 (F = 4.319, p = 0.041); item 8 (F = 4.269, p = 0.041); item 9 (F = 10.761, p = 0.001); item 10 (F = 170.433, p < 0.001); and item 11 (F = 4.075, p = 0.046).

CONCLUSIONS

The results suggest that participation in a moderate physical exercise program one year prior may have equipped older adults with better coping mechanisms to navigate the stress and isolation imposed by the COVID-19 lockdown, as reflected by their enhanced scores on quality-of-life components pertaining to mental well-being. Exercise may confer a protective effect against the adverse psychological impacts of stressful events like the pandemic, even among older adults with chronic conditions. This study underscores the potential benefits of exercise interventions for promoting quality of life and preventing mood disorders in the elderly population.

Loneliness and its correlation with self-care and activities of daily living among older adults: a partial least squares model

BACKGROUND

The growing elderly population worldwide is accompanied by an increased disrupting daily activities and self-care. Neglecting the multifaceted needs of the elderly can lead to detrimental effects such as loneliness or social isolation, threatening healthy aging. Self-care is a key strategy to enhance daily functioning and mitigate feelings of loneliness among the elderly. This study was conducted with the aim of investigating the feelings of loneliness and its relationship with self-care and Activities of Daily Living (ADL) among the older adults of Tabriz city.

METHODS

In this observational cross-sectional study, we engaged 315 older adults using a simple random sampling. Participants were selected randomly from Iran's Integrated Health System (IIHS) framework. Three questionnaires including de Jong Gierveld Loneliness Scale, Persian version of self-care scale, and ADL-Katz were used for data collection. The Partial Least Squares and Spearman's correlation were used to investigate the relationships between demographic characteristics, loneliness, self-care, and ADL.

RESULTS

The sample comprised 315 respondents 51.1% were female, 49.5% had a middle school literacy and 86% were married. A significant negative relationship was observed between loneliness and self-care (P < 0.001 and r =-0.311). Demographic characteristics, including age and marital status, were found to negatively moderate the relationship between self-care (path coefficient - 0.07, P = 0.044) and positively moderate the relationship with loneliness (path coefficient 0.29, p < 0.001). ADL was positively associated with self-care (path coefficient 0.41, p = 0.046) and also a direct and significant relationship was observed between ADL and daily self-care (P < 0.001 and r = 0.335).

CONCLUSION

This study underscores the complex interplay between loneliness, self-care, and ADL. It highlights the need for interventions that address emotional health and daily living skills as part of comprehensive self-care strategies. Further research is needed to explore these relationships in more detail and to develop targeted interventions for different demographic groups.

Trust in primary health care and COVID-19 vaccine uptake among Iranian pediatric: a web-based cross-sectional survey

BACKGROUND

Children are the most vulnerable group to diseases. Thus, it's critical to evaluate parents' or guardians' willingness to vaccinate their children. This study aims to investigate the prevalence and predictors of pediatric COVID-19 vaccination in Iran and its relationship with trust in the Primary Health Care (PHC) system.

METHOD

A cross-sectional online survey of 549 Iranian parents was conducted between January and March 2023. This study collected data from all provinces of Iran using a questionnaire shared on Google Forms and various social media platforms. After considering various background factors, we used a multivariable logistic regression model. This model explored how trust in the PHC system and parent-related and child-related factors were related to parents' vaccine uptake for their children.

RESULTS

Of 549 parents aged between 19 and 67 years (median = 38 years), 65.2% (358) were female. The prevalence of vaccine uptake among parents was 46.8%. After adjusting for background features, child's age (adjusted odds ratio [AOR] 0.81, 95% CI 0.71-0.91), vaccine doses (1-dose: AOR 14.72, 95% CI 6.44-33.65, 2-dose: AOR 32.54, 95% CI 15.22-69.57), child's disease (AOR 5.31, 95% CI 2.19-12.85), and trust in PHC (AOR 1.01, 95% CI 1.00-1.02) were associated with parental uptake of the COVID-19 vaccine.

CONCLUSIONS

The findings of this study suggest that the child's age, vaccine doses received, diseases, and trust in PHC are significant predictors of parental uptake of the COVID-19 vaccine for children in Iran. The results can be used in service planning regarding children's COVID-19 vaccination.

COVID-19 outbreaks in residential aged care facilities: an agent-based modeling study

Introduction

A disproportionate number of COVID-19 deaths occur in Residential Aged Care Facilities (RACFs), where better evidence is needed to target COVID-19 interventions to prevent mortality. This study used an agent-based model to assess the role of community prevalence, vaccination strategies, and non-pharmaceutical interventions (NPIs) on COVID-19 outcomes in RACFs in Victoria, Australia.

Methods

The model simulated outbreaks in RACFs over time, and was calibrated to distributions for outbreak size, outbreak duration, and case fatality rate in Victorian RACFs over 2022. The number of incursions to RACFs per day were estimated to fit total deaths and diagnoses over time and community prevalence.Total infections, diagnoses, and deaths in RACFs were estimated over July 2023-June 2024 under scenarios of different: community epidemic wave assumptions (magnitude and frequency); RACF vaccination strategies (6-monthly, 12-monthly, no further vaccines); additional non-pharmaceutical interventions (10, 25, 50% efficacy); and reduction in incursions (30% or 60%).

Results

Total RACF outcomes were proportional to cumulative community infections and incursion rates, suggesting potential for strategic visitation/staff policies or community-based interventions to reduce deaths. Recency of vaccination when epidemic waves occurred was critical; compared with 6-monthly boosters, 12-monthly boosters had approximately 1.2 times more deaths and no further boosters had approximately 1.6 times more deaths over July 2023-June 2024. Additional NPIs, even with only 10-25% efficacy, could lead to a 13-31% reduction in deaths in RACFs.

Conclusion

Future community epidemic wave patterns are unknown but will be major drivers of outcomes in RACFs. Maintaining high coverage of recent vaccination, minimizing incursions, and increasing NPIs can have a major impact on cumulative infections and deaths.

The impact of the COVID-19 pandemic on neurosurgery in the elderly population in Sweden

BACKGROUND

The COVID-19 pandemic prompted a refocus of health care resources to acute care which has impacted on the capacity of healthcare systems to conduct neurological surgeries. The elderly population has been shown to be particularly vulnerable to the consequences of the pandemic. Less neurosurgery can result in great impact on public health by increasing morbidity and mortality in patients with malignancies and traumatic injuries. The aim of this study was to investigate the effects of the COVID-19 pandemic on neurosurgical procedures in the elderly population in Sweden.

METHODS

In this retrospective observational study, the reported incidence of all neurosurgical procedures registered in the 21 Regions of Sweden during 2015-2021 in people aged 65 year or older was collected. Surgical procedures were classified according to the NOMESCO system of classification. Neurosurgery incidence was defined as the number of NOMESCO associated interventions per 100.000 inhabitants. ICD-10 codes associated with neurosurgery-related diagnoses and deaths were also collected. Expected incidence of neurosurgery, neurosurgery-associated deaths and brain cancer diagnoses was estimated and compared to actual outcomes. Decrease in the incidence of neurosurgery was compared to regional COVID-19 incidence, other types of surgery and surgery waiting times.

RESULTS

The incidence of several categories of neurosurgery decreased in Sweden during 2020 and 2021, although not as much as other surgical categories. Women were more affected than men by the decrease in neurosurgery which could be partly explained by a decrease in brain cancer diagnoses amongst women. There was an association between regional decrease in neurosurgery incidence and longer surgery waiting time. COVID-19 incidence in the region did not have an effect on regional decreases in neurosurgery incidence.

CONCLUSIONS

The COVID-19 pandemic resulted in a reduction in the number of neurosurgical procedures performed in Sweden during 2020-2021, although not as much as in other European countries. There was regional difference in Sweden with respect to number of surgeries, and waiting time for elective surgeries although there was no increase in mortality.

Psychological well-being and factors affecting it after the COVID-19 pandemic

Introduction

The COVID-19 pandemic has enormously impacted human activity worldwide, partly due to many governments issuing stay-at-home orders and limiting the types of social interactions citizens can engage in. Hence, this study investigated psychological well-being and factors affecting it after the COVID-19 pandemic.

Methods

A total of 345 participants were recruited in the study. This research was conducted between February and May 2023 in Sarab, East Azerbaijan, Iran. To measure the data, valid and reliable instruments of Goldberg's General Health Questionnaire (GHQ-28), Multidimensional Health Locus of Control (MHLC), interpersonal support evaluation list (ISEL-SF), and health-protective behaviors checklist instrument were used.

Results

According to the results, health locus of control (r = 0.227; p < 0.001), social support (r = 0.339; p < 0.001), and COVID-19 preventive behaviors (r = 0.376; p < 0.001) were positively correlated with psychological well-being. The strongest correlation was observed between psychological well-being and protective behaviors (r = 0.376; p < 0.001). In the hierarchical regression model, total, demographic characteristics along with health locus of control, social support, covid-19 preventive behaviors, and history of COVID-19 infection were able to explain 57.4% of the variation in psychological well-being.

Discussion

Public healthcare providers' and policymakers' preventive and supportive actions are highly advised for promoting health locus of control and social support in adults after the COVID-19 pandemic. In addition, it is better to include a community's social and environmental changes.

Unleashing the link between the relaxation of the COVID-19 control policy and residents' mental health in China: the mediating role of family tourism consumption

Objective

COVID-19 has negatively influenced industrial development, family consumption, and residents' mental health. Unfortunately, it has not yet been studied whether this adverse situation can be alleviated after the relaxation of the COVID-19 control policy (RCC). Therefore, this study aimed to analyze the effect of the RCC on the resident's mental health and the mediating effect of family tourism consumption.

Methods

By using the PSM and mediating effetc model to research the panel data of two periods (April 2021 and April 2023) for Shaanxi province, China.

Results

The RCC negatively inhibited the mental health severity of residents, and the mental health severity decreased by 0.602. In particular, the RCC showed the most substantial negative effect on residents' stress, followed by anxiety and depression. Meanwhile, it is found that the impact of the RCC on the mental health of residents is highly heterogeneous. The RCC indicates a linear significant effect on the mental health of residents under 60 years of age, while the results were found insignificant for residents above 60 years of age. Meanwhile, the RCC's improvement effect on urban residents' mental health is greater than that of rural residents. In addition, mechanism analysis showed that tourism consumption plays a mediating role in the influence of the RCC on the mental health of residents, and the mediating effect accounted for 24.58% of the total effect.

Conclusion

Based on the findings, the study proposes that government and policymakers should strengthen mental health intervention, improve access to mental health counseling, stimulate economic development, expand the employment of residents, and track the mutation of the novel coronavirus.

Availability of malaria diagnostic tests, anti-malarial drugs, and the correctness of treatment: a systematic review and meta-analysis

BACKGROUND

Health facilities' availability of malaria diagnostic tests and anti-malarial drugs (AMDs), and the correctness of treatment are critical for the appropriate case management, and malaria surveillance programs. It is also reliable evidence for malaria elimination certification in low-transmission settings. This meta-analysis aimed to estimate summary proportions for the availability of malaria diagnostic tests, AMDs, and the correctness of treatment.

METHODS

The Web of Science, Scopus, Medline, Embase, and Malaria Journal were systematically searched up to 30th January 2023. The study searched any records reporting the availability of diagnostic tests and AMDs and the correctness of malaria treatment. Eligibility and risk of bias assessment of studies were conducted independently in a blinded way by two reviewers. For the pooling of studies, meta-analysis using random effects model were carried out to estimate summary proportions of the availability of diagnostic tests, AMDs, and correctness of malaria treatment.

RESULTS

A total of 18 studies, incorporating 7,429 health facilities, 9,745 health workers, 41,856 febrile patients, and 15,398 malaria patients, and no study in low malaria transmission areas, were identified. The pooled proportion of the availability of malaria diagnostic tests, and the first-line AMDs in health facilities was 76% (95% CI 67-84); and 83% (95% CI 79-87), respectively. A pooled meta-analysis using random effects indicates the overall proportion of the correctness of malaria treatment 62% (95% CI 54-69). The appropriate malaria treatment was improved over time from 2009 to 2023. In the sub-group analysis, the correctness of treatment proportion was 53% (95% CI 50-63) for non-physicians health workers and 69% (95% CI 55-84) for physicians.

CONCLUSION

Findings of this review indicated that the correctness of malaria treatment and the availability of AMDs and diagnostic tests need improving to progress the malaria elimination stage.
