Abstract
Objective To determine the association between children's autism spectrum disorder with parental anxiety and burnout in Karachi, Pakistan. Methods A cross-sectional study was conducted at Baqai Institute of Health Sciences, Baqai Medical University from December 2022, to November, 2023. Data collection was performed at three rehabilitation centers for autistic children in Karachi. The study population consisted of parents of autistic children. GAD-7 and Parental Burnout Assessment scales were used to assess the anxiety and burnout level among parents. Data were analyzed using SPSS version 21. Results The study results showed that 49 (24.5%) parents had moderate anxiety while 38 (19.0%) had severe anxiety. Besides, 36 (18.0%) of them were at risk of burnout while 8 (4.0%) were diagnosed with burnout. Furthermore, gender of child (p=0.01), father's age (p=0.015) and type of family (p=0.001) were significantly associated with the anxiety level whereas father's age (p=0.036), father's education (p=0.006) and type of family (p=0.046) were significantly associated with the burnout level of the parents. Conclusion This study results showed significant association of certain child and parental characteristics such as child's gender, father's age and type of family with parental anxiety level and of father's age, father's education and type of family with parental burnout.

Abstract
INTRODUCTION Mental health problems are pervasive nowadays. Adolescents are often expected to balance academic performance with familial obligations and work to support the family financially if they belong to low-socio-economic areas. These pressures can lead to Anxiety, stress, and even depression. OBJECTIVE The study's main objective is to assess the association of gender, parenting style, eating habit, and screen timing with the level of Anxiety among school-going adolescents in three peri-urban areas of Karachi, Pakistan. METHODOLOGY A school-based cross-sectional study was conducted among adolescents of age group 10-19 years using the Generalized Anxiety Disorder-7 (GAD-7) scale in two months in, three populated peri-urban areas of Karachi, Pakistan. Collected Data was analyzed by statistical software SPSS version with 80% response rate. FINDING In our collected data, 544 students participated; 313 (57%) were female, and 231(42%) were male. Among them 173(33%) participants showed moderate to severe level of anxiety out of which 140(26%) were female and 33(7%) were male. As per our study, strict Parenting style plays a significant role in developing moderate to severe 108(20%) levels of Anxiety, shown among adolescents in the studied population. In addition to this, those who do not take tuition 115 (21%), do not use transport to school 91(16%), spend significant time in games on mobile and computer 101 (18%), and have no involvement in physical activities 172 (31%) show more moderate to severe level anxiety than others factors. A significant multivariate association between level of anxiety with gender, school commute, type of lunch Intake, smoker family member at home, physical activity, video game, tuition and strict parent. CONCLUSION This study concluded that there are various factors which have great association with anxiety and can affect adolescents' mental health badly. The factors were parental strictness, video game playing, a sedentary lifestyle, and the smoking habits of family members. Children and adolescents must be evaluated as soon as possible while they are still young to prevent mental health issues.

Increase in presentations with new-onset psychiatric disorders in a psychiatric emergency department in Berlin, Germany during the second wave of the COVID-19 pandemic - a retrospective cross-sectional study. Front Psychiatry 2023; 14:1240703. [PMID: 37904853 PMCID: PMC10613500 DOI: 10.3389/fpsyt.2023.1240703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 09/25/2023] [Indexed: 11/01/2023] Open
Abstract
Introduction While numerous studies have identified an increase in symptoms of depression as well as anxiety and distress due to the COVID-19 pandemic, relatively few studies have investigated the new-onset of psychiatric diseases during the pandemic. Methods This study focuses on the number of psychiatric new-onset diagnoses in a psychiatric emergency department (pED) in Berlin, Germany during the second wave of the pandemic (i.e. from 09/15/2020 to 03/01/2021 = COVID-19-period) compared to pre-pandemic times (09/15/2019 to 03/01/2020 = control period). We focused on diagnostic subgroups and performed logistic regression analysis to investigate potential risk groups based on covariables such as age, gender, homelessness, attending in police custody and familial relationship. Results Overall, there was a 59.7% increase in new-onset psychiatric diagnoses during the COVID-19-period. Increases in the following diagnoses were observed: new-onset of substance-related and addictive disorders (+192.5%), depressive disorders (+115.8%), schizophrenia spectrum and psychotic disorders (+113.3%) and anxiety disorders (+63.6%). These diagnostic subgroups, together with attending in police custody, were found to predict pED presentations with new-onset during the COVID-19-period. Interestingly, in the group of new-onset psychiatric diseases in the COVID-19-period, higher amounts of job loss and living alone as well as a relative decrease in familial relationships were observed. Discussion COVID-19 infections and post-COVID-19 syndrome are unlikely to have played a substantial role in the increase of new-onset diseases in this study. Conclusion: Our findings underline the role of indirect factors in new-onset of psychiatric diseases during the pandemic and should be a caveat for future pandemic control policies.

Abstract
Indian subcontinent has high mental heath burden and low resources to cope the mental health challenges. Assessment of impact of COVID-19 pandemic on the mental health would help to prioritize the resource allocations. We aimed to assess the impact of COVID-19 on the mental health of people in the Indian subcontinent. Following the PRISMA 2020 guideline, a scoping review was performed by systematically searching the PubMed, Scopus, and Embase databases to identify original studies that assessed mental health conditions during the COVID-19 pandemic in the Indian subcontinent. In this review, a total of 34 studies conducted between 2020 and 2022 were analyzed. The prevalence of anxiety disorders was found to range widely, from 2.5% in North Indian urban slum to 53% in Bangladesh and 21.7% in Pakistan. Similarly, the prevalence of depression varied widely, with rates ranging from 3.5% in North India to 29.8% in Pakistan. The prevalence of stress-related problems ranged from 18.3% in Pakistan to 59.7% in Bangladesh. Factors such as female gender, married status, healthcare workers, and mental illness were identified as important predictors of anxiety and depressive disorders. The impact of COVID-19 pandemic on mental health in Indian subcontinent varies widely based on study population and methods. Therefore, a cautious interpretation is needed while generalizing the study results.

Abstract
BACKGROUND In Pakistan, the fourth wave of COVID-19 is causing an increasing number of positive cases. This fourth wave may be a risky aspect of mental health issues for COVID-19 patients. This quantitative study is designed to understand the stigmatization, and panic disorder and to explore the mediating role of death anxiety among patients of COVID-19 during the fourth wave of novel coronavirus. METHODS The study was conducted using a correlational research design. The survey was carried out by utilizing a questionnaire with a convenient sample technique. The sample of the study was comprised of 139 patients with COVID-19. Data were collected through Stigma Scale for Chronic Illnesses (SSCI), The Panic Disorder Severity Scale (PDSS), and Death Anxiety Inventory. RESULTS Results show that stigma is significantly positively related to panic disorder and death anxiety. Furthermore, panic disorder is also significantly positively related to death anxiety. Results also indicate that stigmatization is a significant positive predictor for death anxiety and panic disorder. Moreover, results indicate that death anxiety has a mediating role in the relationship between stigmatization and panic disorder with age and gender as covariates. CONCLUSION This study would be helpful for people around the world to understand this threatening contagious virus so they wouldn't stigmatize infected ones. Additional research is required for the sustainable improvement of anxiety over time.

Abstract
AIM The present study addressed overcoming the lacunae in the literature of psychiatric manifestations associated with rhino-orbital mucormycosis. The current study aimed to assess the symptoms of depression, anxiety, stress, coping measures, suicidal intent, and visual disability in patients of rhino-orbital mucormycosis (ROM) during the epidemic of the disease at the nodal tertiary care center in North India. METHODS Fifty-four inpatients of laboratory-proven rhino-orbital mucor-mycosis (ROM) were included for an observational, cross-sectional study at nodal, designated COVID-19, and mucormycosis treating tertiary care hospital. Patients with Hindi Mini-Mental State Examination score <24, prior psychiatric illness, and severely ill requiring ventilator support were excluded. The psychological variables were assessed using Depression, Anxiety, and Stress Scale 21 (DASS 21), Beck's Suicide intent Scale, Coping Scale Questionnaire, and Visual disability scale (IND-VFQ33). Their socioeconomic status was assessed using the Modified Kuppuswamy Scale. RESULTS Ninety percent of patients with ROM had diabetes mellitus. The majority (44%) of patients belonged to lower socioeconomic strata. Higher frequencies of severe depression (28%), extremely severe anxiety (26%), and mild stress (17%) were noted in the study participants. On the Tukey test, depression score was higher in patients of ROM compared to COVID (with ROM) (p-value= 0.016). On Tukey analysis, anxiety score was significantly higher in ROM patients compared to COVID (with ROM) patients (p-value = 0.018). Coping scores were significantly higher in COVID (with ROM) patients compared to ROM patients (p value = 0.035). Mild to moderate visual disability was noted in the study participants. Conclusion: The current study reflects the association of higher depression and anxiety scores in cases with ROM that indicated higher mental health needs. Early assessment, early detection, and early intervention for psychological help, along with the multidisciplinary team, helped to improve the overall psychological outcome of the affected patients.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) tightly traps modern people. Its incidence shows an increased peak during the 2019 novel coronavirus (COVID-19) epidemic. Acupuncture is regarded as an effective way to relieve anxiety symptoms. However, there are still controversies. This study aimed to systematically evaluate the clinical efficacy of acupuncture in patients with GAD. METHODS Four English and 3 Chinese databases were searched from their inception to January 2022. Only randomized controlled trials (RCTs) in which acupuncture was the main intervention were included. The literature was independently screened and extracted by two investigators. The Cochrane Bias Risk Assessment Tool was used for quality evaluation. Analyses were conducted by RevMan 5.3.0 and STATA 15.0 software. The primary outcome was the Hamilton Anxiety Scale (HAMA). The secondary indicators were the total effective rate, the Self-Rating Anxiety Scale (SAS), and the Treatment Emergent Symptom Scale (TESS). RESULTS Twenty-seven studies were included with a total of 1782 participants. The risk of performance bias or reporting bias for most of the included trials was unclear. Combined results showed the acupuncture group had better outcomes in the HAMA score [MD = -0.78, 95%CI (-1.09, -0.46)], the total effective rate [RR = 1.14, 95%CI (1.09, 1.19)], the SAS score [MD = -2.55, 95%CI (-3.31, -1.80)] compared with the control group. Regarding the number of adverse events, the acupuncture group was safer than the control group and scored less grade in the TESS score [MD = -1.54, 95%CI (-1.92, -1.17)]. CONCLUSIONS Acupuncture can effectively relieve the anxiety symptoms of generalized anxiety disorder patients with fewer side effects, but randomized controlled trials with large sample size and high quality are also required to support the result.

Burnout in health care workers during the fourth wave of COVID-19: A cross sectional study from Pakistan. Ann Med Surg (Lond) 2022; 80:104326. [PMID: 35958288 PMCID: PMC9357282 DOI: 10.1016/j.amsu.2022.104326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/30/2022] [Accepted: 07/31/2022] [Indexed: 11/29/2022] Open
Abstract
Objective To assess the burnout among the healthcare workers during the fourth wave of COVID-19. Methods In this cross-sectional study, burn out was measured in health care professionals using the MBI scale inventory during the fourth wave of COVID-19. Age, gender, marital status, having children, hospital, job type, experience, and workload, as well as the severity of burnout in each subscale, were all measured. We used the chi-square test to detect the difference between the level of burnout and other demographic variables, and a multiple logistic regression test was used to define the predicted correlation between the high level of burnout and the risk factors. Odds ratios and corresponding 95% confidence intervals (CI) were reported. A p-value of less than 0.05 indicated a statistically significant outcome. Results Out of 776 healthcare workers who participated in our study, 468 (63.2%), 161 (21.7%) and 112 (15.1%) participants experienced low, moderate and high levels of emotional exhaustion, respectively. For the depersonalization subscale, 358 (48.3%), 188 (25.4%) and 195 (26.3%) people suffered from low, moderate, and high levels of depersonalization, respectively while 649 (87.6%), 40 (5.4%) and 52 (7.0%) respondents had low, moderate and high levels in the personal accomplishment subscale, respectively. Conclusion During the fourth wave of COVID-19, the healthcare workers reported increased level of burnout overall possibly due to the long term physical and mental impacts that the pandemic has had over the time. Moreover, healthcare workers in Pakistan were more prone to burnout as compared to other countries. Higher levels of burnout were observed in the fourth wave of COVID-19, possibly due to the long term physical and mental impacts that the pandemic has had over time. Healthcare workers in Pakistan were more prone to burnout as compared to other countries. This study yielded key findings that have important implications for preventing and reducing burnout in hospital settings.

Time-Series Associations between Public Interest in COVID-19 Variants and National Vaccination Rate: A Google Trends Analysis. Behav Sci (Basel) 2022; 12:bs12070223.

Abstract
The emergence of a constantly mutating novel virus has led to considerable public anxiety amid the COVID-19 pandemic. Information seeking is a common strategy to cope with pandemic anxiety. Using Google Trends analysis, this study investigated public interest in COVID-19 variants and its temporal associations with the disease-prevention measure of vaccination during the initial COVID-19 vaccine rollout period (13 December 2020 to 25 September 2021). Public interest was operationalized as the relative search volume of online queries of variant-related terms in the countries first affected by the Alpha, Beta, and Delta variants: the UK, South Africa, and India, respectively. The results show that public interest in COVID-19 variants was greater during the Delta-variant-predominant period than before this period. The time-series cross-correlation analysis revealed positive temporal associations (i.e., greater such public interest was accompanied by an increase in national vaccination rate) tended to occur more frequently and at earlier time lags than the negative temporal associations. This study yielded new findings regarding the temporal changes in public interest in COVID-19 variants, and the between-country variations in these public interest changes can be explained by differences in the rate and pace of vaccination among the countries of interest.
