Mental health, risk perception, and coping strategies among healthcare workers in Egypt during the COVID-19 pandemic.

BACKGROUND: Coronavirus disease-19 emerged in December 2019. Healthcare workers were exposed to this highly infectious virus during the pandemic and suffered several social and psychological consequences, such as anxiety, psychological distress, and burnout. OBJECTIVES: To assess the psychological distress, anxiety, depression, coping strategies, risk perception, and attitude toward interprofessional teamwork among Egyptian healthcare workers during the COVID-19 pandemic. METHODS: We conducted a cross-sectional online survey which consisted of five sections. The primary outcomes were anxiety (GAD-7), depression (PHQ-9), risk perception towards COVID-19, interprofessional teamwork attitude, and coping strategies during the Coronavirus disease-19 pandemic. The web-based questionnaire was distributed to Egyptian healthcare workers from the 20th of April 2020 to the 20th of May 2020. A snowball sampling method was used. Regression analysis was conducted to test the relationship between the socioeconomic characteristics and the previously mentioned outcomes. RESULTS: A total of 403 participants responded to the online questionnaire. The majority were females (70.5%) and within the age group of 26-40 years (77.7%), with 2-5 years of work experience (43.2%). Most participants were pharmacists (33%) and physicians (22.1%). Eighty-two participants (21%) reported moderate to severe anxiety, and 79 participants reported (19.4%) moderate to severe depressive symptoms. In the univariate model, the marital status was associated with depression (OR 0.47, 95% CI 0.28-0.78), anxiety (OR 0.52, 95% CI 0.32-0.85), and an attitude toward interprofessional teamwork (ß = -1.96 95% CI -2.72 to -1.2). Providing direct care to the patients was associated with lower anxiety symptoms (AOR 0.256, 95% CI 0.094-0.697). More severe anxiety and depressive symptoms were associated with difficulties in everyday life and the professional work environment (AOR 4.246 and 3.3, P = 0.003 and 0.01, respectively). Availability of mental health facilities at the workplace was associated with a lower risk perception towards COVID-19 (ß = -0.79, 95% CI -1.24 to -0.34) and a more positive attitude towards teamwork (ß = 2.77 95% CI 1.38-4.15). CONCLUSIONS: According to our results, the COVID-19 pandemic was associated with mild anxiety and depression among healthcare workers in Egypt, especially pharmacists and physicians. We recommend more research targeting the mental health of healthcare workers in Egypt. If proven cost-effective and needed, wide-scale mental health screening and public health campaigns can facilitate effective prevention and treatment strategies. In addition, the availability of mental health facilities at the workplace could alleviate some of the risk perception associated with health emergencies and improve interprofessional teamwork.

Serum plasminogen activator inhibitor-1 levels in patients with major depressive disorder vs. healthy controls: a systematic review and meta-analysis.

INTRODUCTION: Major depressive disorder (MDD) is a severe mental health condition that affects millions of people worldwide. Etiologically, several factors may play a role in its development. Previous studies have reported elevated plasminogen activator inhibitor-1 (PAI-1) levels in patients with depression, suggesting that PAI-1 levels might be linked to the etiology of MDD. METHODS: We systematically searched the following online databases: MEDLINE, Scopus, and Web of Science up to September 10, 2020, to identify studies in which PAI-1 levels were reported in subjects with MDD. Subsequently we used RevMan 5.3 to perform a meta-analysis of data extracted from the included studies using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and PICO criteria for the search and analysis. RESULTS: Six studies that reported mean ± standard deviation (SD) were included in the analysis, with a total of 507 MDD patients and 3,453 controls. The overall standardized mean difference (SMD) was 0.27 (95% confidence interval [95% CI] 0.01-0.53). PAI-1 serum levels were 0.27 SDs higher in MDD patients than in controls. The test for overall effect was significant (z = 2.04, p = 0.04). Substantial heterogeneity was detected among the studies, demonstrated by the inconsistency test (I² = 72%) and the chi-square test (χ² = 18.32; p = 0.003). CONCLUSIONS: This systematic review and meta-analysis showed that MDD might be related to elevated PAI-1 levels. We propose larger prospective clinical studies to further investigate this clinical correlation and validate the clinical significance of these observations.

Sonographic reference values of nerve size in children: A systematic review and meta-analysis.

INTRODUCTION/AIMS: Nerve ultrasound is useful in the diagnosis and follow-up of peripheral nerve disorders in children. The aim of this study was to explore and analyze the current literature on nerve cross-sectional area (CSA) in healthy children, with the goal of presenting reference values and discussing their implications. METHODS: We performed a systematic review and meta-analysis of studies that reported ultrasound measurements of the upper or lower limb nerves in healthy children through a search of Web of Science, PubMed, Embase, and Scopus. RESULTS: Sixteen studies with measurements of 10 nerves covering a total of 5149 nerves measured in 823 healthy children (445 boys and 378 girls) were included. Mean nerve CSA increased with age in the median nerve at the middle and lower third of the upper arm, mid-forearm, and distal wrist crease, the ulnar nerve at the middle third of the upper arm and elbow, the radial nerve at the spiral groove, and the tibial nerve at the popliteal fossa. Growth charts for nerve CSA for different age groups were developed. DISCUSSION: This meta-analysis provides robust reference values for nerve CSA at different sites in children, and this can inform clinical practice and assist in identifying nerve enlargement. Moreover, it identifies the strength and quality of the current published data. We recommend future studies divide their samples into smaller age subgroups and standardize the anatomic site of measurement.

Could Osteopontin be a useful biomarker in the diagnosis and severity assessment of osteoarthritis? A systematic review and meta-analysis of recent evidence.

PURPOSE: Osteoarthritis (OA) patients demonstrated higher Osteopontin (OPN) plasma, serum, and synovial fluid concentrations than healthy individuals. In the present study, we aimed to investigate whether OPN could be used as a diagnostic or prognostic marker for OA symptom/disease severity. METHODS: Using Web of Science, PubMed, Scopus, and Embase, we conducted a systematic review and meta-analysis of studies that measured OPN levels in OA patients' plasma, serum, or synovial fluid. After setting the eligibility criteria, data extraction, and quality assessment of the identified studies, we performed statistical analysis using Revman 5.4 and Open Meta analyst. RESULTS: OPN has been found to be associated with advanced knee joint damage in OA patients. In addition, higher expression of OPN is thought to be associated with disease progression. Nevertheless, further studies should examine the role of other markers of chronic bone damage, such as leptin and sclerostin. This systematic review and meta-analysis included 14 studies with a total of 776 cases and 530 controls. OPN was significantly elevated in osteoarthritis patients' plasma, serum, and synovial fluid samples, with significant heterogeneity between studies. CONCLUSION: We recommend that OPN plasma and synovial fluid levels be measured as a diagnostic and prognostic marker to determine the severity of OA symptoms.

The potential association between psychiatric symptoms and the use of levonorgestrel intrauterine devices (LNG-IUDs): A systematic review.

BACKGROUND: Levonorgestrel (LNG)-intrauterine devices (IUDs) are an effective method of contraception; however, there is growing evidence regarding potential psychiatric side effects such as depressive symptoms, anxiety, and suicidal thoughts. Therefore, we conducted this systematic review to summarise the psychiatric effects of using LNG-IUDs. METHODS: We searched six databases (MEDLINE, Web of Science, Scopus, Science Direct, Cochrane Library, and PsycInfo), and we included all study designs. The included studies were extracted, quality assessed, and qualitatively summarised. RESULTS: Out of the screened studies, only 22 were finally included. While ten studies showed increased depressive symptoms, two studies showed reduced symptoms. Moreover, one study showed increased anxiety, another one reported an increased risk of suicide, four studies concluded no association with depressive symptoms, and four other studies showed uncertainty about a potential association but mentioned other psychiatric symptoms. CONCLUSION: Despite unreliable data, many studies report psychiatric symptoms associated with LNG-IUDs, predominantly depression. Gynaecologists, general practitioners, and psychiatrists should therefore be aware of these potential risks, especially depressive symptoms and suicidality. Counselling patients about these risks should be mandatory. Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives.KEY MESSAGESMany researchers are reporting adverse psychiatric events associated with levonorgestrel intrauterine devices (LNG-IUDs).Despite their effectiveness, a proper psychiatric assessment should be done before inserting LNG-IUDs.Proper counselling regarding the depressive symptoms and suicidality should be done by the treating obstetrician.Further studies should investigate the absolute risk of mental disorders associated with LNG-IUDs and other hormonal contraceptives.

Sonographic Reference Values of Vagus Nerve: A Systematic Review and Meta-analysis.

PURPOSE: To establish the first comprehensive and standardized set of vagus nerve (VN) sonographic reference values across all the published studies that can be used to standardize and guide clinical practice and research. METHODS: This systematic review includes all possible available data from a total of 27 studies and 21 of them were included in the meta-analysis having a total of 864 participants. RESULTS: The overall mean cross-sectional area ranged from 2.29 to 2.76 mm2 for the right VN and from 1.83 to 2.23 mm2 for the left VN with 95% confidence interval. Sonographic reference values of VN at common carotid artery bifurcation, thyroid gland, and cartilage as well as other anatomic landmarks were provided. CONCLUSIONS: The mean cross-sectional area of the right VN of 2.53 mm2 and the left one of 2.03 mm2 can be considered as sonographic reference values in healthy adults. This review provides these reference values to be considered in the further sonographic evaluation of VNs.

The effect of endurance, resistance training, and supplements on mitochondria and bioenergetics of muscle cells.

Bioenergetics is the study of energy flow between biological systems and the surroundings and is measured quantitatively. Energy flow can be affected by many variables, including lifestyle and exercise, where exercise comes in different types; endurance and resistance training play significant roles in enhancing bioenergetics and promoting health. In addition, a supplementary diet supports recovery and energy production. This review aims to study the effect of endurance training, resistance training, and supplement intake on the muscle cell's bioenergetics. As a conclusion of the information presented in this mini-review, it was found that resistance, endurance training, and supplements can increase mitochondrial biogenesis, fat oxidation, myofibril synthesis, and increase VO2 max.

Vagus nerve ultrasonography in Parkinson's disease: A systematic review and meta-analysis.

OBJECTIVES: Vagus nerve (VN) has been suggested as one of the major routes of Parkinson's disease (PD) progression from enteric nervous system to brain. Therefore, the recent studies have investigated the VN structurally, with a focus on the changes in its size in PD patients using high-frequency ultrasonography. This systematic review and meta-analysis aims to evaluate VN size via ultrasound in PD compared to controls. METHODS: Totally, five studies were included with a total of 238 participants (128 PD patients and 111 controls). RESULTS: The estimate mean difference in four studies showed that the VN CSA was smaller in PD patients with 0.29 mm2 (95% CI, -0.52 to -0.06) and 0.23 mm2 (95% CI, -0.42 to -0.05) for right and left VNs respectively. The test for overall effect was significant for both measurements (p = 0.01). CONCLUSIONS: This review reveals that there is a degree of vagus nerve atrophy in PD which could be detected sonographically with high confidence, thus can be used as a marker for vagus neuronal lesion or neuropathy. Further studies are needed to examine its clinical correlation thoroughly.

Factors Influencing Decision Making Regarding the Acceptance of the COVID-19 Vaccination in Egypt: A Cross-Sectional Study in an Urban, Well-Educated Sample.

BACKGROUND: The COVID-19 pandemic has raised the necessity to rapidly develop safe and effective vaccines to limit the spread of infections. Meanwhile, vaccine hesitancy is a significant barrier to community vaccination strategies. METHODS: An internet-based cross-sectional survey was conducted from March to April 2021 during the start of the vaccination campaigns. RESULTS: A total of 1009 subjects participated, and the mean age (±SD) was 29.11 ± 8.2 years. Among them, 68.8% believed that vaccination is an effective method to control the spread of the disease, 81.2% indicated acceptance of the vaccine, and 87.09% reported that their doctor's recommendation was essential for decision making. After adjusting for socioeconomic characteristics, rural residency (AOR 1.783, 95%CI: 1.256-2.531), working a part-time job (AOR 2.535, 95%CI: 1.202-5.343) or a full-time job (AOR 1.951, 95%CI: 1.056-3.604), being a student (AOR 3.516, 95%CI: 1.805-6.852) and having a partner (AOR 1.457, 95%CI: 1.062-2.00) were significant predictors for higher vaccine acceptance among the study participants. Believing in the vaccine's efficacy showed the strongest correlation with vaccine acceptance (Spearman's r = 0.309, p < 0.001). CONCLUSIONS: Although general vaccine acceptance is high (32.85%) in participants in our study, gender and geographic disparities were observed in the investigated urban population of young, well-educated Egyptians.
