Effectiveness of life review on depression among elderly: a systematic review and meta-analysis

Introduction: depression is considered one of the most common obstacles to daily life activities and quality of life in the elderly. Evidence is accumulating regarding the effectiveness of reminiscence and life review interventions in reducing depression and raising well-being in the elderly. The aim of this review was to determine the effects of life review interventions on depression outcomes among the elderly. Methods: a search of the literature was performed through 11 electronic databases to identify all randomized controlled trials studies that examine life review effects on depression among the elderly. For each study, the effect size (Cohen's d) between groups (life review vs. control) differences in depression scores for post-intervention and follow-up intervention were computed. Results: in total, 15 studies were met the inclusion criteria and was evaluated by meta-analysis. Results showed that the life review group has a large effect on reducing depression level than the control group on post-intervention and follow-up. After conducted sensitivity analysis, a moderate effect (effect size=-0.54; 95% CI=-0.71 to -0.36; p<0.05) and small effect (effect size=-0.20; 95% CI=-0.41 to -0.01; p<0.05) were found on post-intervention and follow-up, respectively. Conclusion: through this systematic review and meta-analysis, the overall results showed a moderate effect to reducing depression levels among the elderly in the life review group after carrying out post-intervention measurements, while in the follow-up the effect was small. This review indicates that life review intervention is one of the options likely to be of benefit for elderly in primary care settings, but further research can be focused on intervention and follow-up durations to obtain long-term effects

Reentrant Melting of Soliton Lattice Phase in Bilayer Quantum Hall System

At large parallel magnetic field $B_\parallel$, the ground state of bilayer quantum Hall system forms uniform soliton lattice phase. The soliton lattice will melt due to the proliferation of unbound dislocations at certain finite temperature leading to the Kosterlitz-Thouless (KT) melting. We calculate the KT phase boundary by numerically solving the newly developed set of Bethe ansatz equations, which fully take into account the thermal fluctuations of soliton walls. We predict that within certain ranges of $B_\parallel$, the soliton lattice will melt at $T_{\rm KT}$. Interestingly enough, as temperature decreases, it melts at certain temperature lower than $T_{\rm KT}$ exhibiting the reentrant behaviour of the soliton liquid phase.Comment: 11 pages, 2 figure

Parental Attitude towards the Prescription of Psychotropic Medications for Mental Disorders in Children in a Tertiary Care University Hospital in Oman

Objectives: This study investigated parental attitudes towards psychotropic drugs for children's mental disorders. Methods: A questionnaire was distributed to parents of children attending a child psychiatry clinic at a tertiary hospital in Muscat, Oman. Similarly, in a small proportion, other caregivers filled out the questionnaire in case the child attended with them. The questionnaire comprised questions regarding parents' opinions, and attitudes about psychotropic medications use. The logistic regression model was used to identify the risk factors associated with parents who prefer to consult a folk healer (FH) for children with mental disorders. Results: A total of 299 parents agreed to participate in the study. The majority of them (81.6%, n=244) agreed that they would give their child psychotropic medications if necessary, but 25.4% of them (n=76) would consult a FH before consulting a psychiatrist if their child experienced psychiatric symptoms. Married parents were 14 times (OR=14.5, p=0.011) more likely to consult a FH than were separated or divorced parents. Caregivers with a monthly income below 500 OMR and between 500-1,000 OMR were two times (OR=2.5, p=0.016) and three times (OR=3.2, p<.001), respectively, more likely to consult a FH than those with a monthly income of more than 1,000 OMR. Parents who disagreed with giving psychotropic medications to their children were three times (OR=3.7, p<.001) more likely to consult a FH than were parents who agreed to give psychotropic medications to their children if necessary. Conclusion: Most parents agreed to give their children psychotropic medications if it were deemed necessary. However, a sizeable proportion of parents and caregivers preferred to consult a FH before accessing mental health services. Keywords: Parents; Children; Attitudes; Psychotropic Drugs; Oma

The fractal heart — embracing mathematics in the cardiology clinic

For clinicians grappling with quantifying the complex spatial and temporal patterns of cardiac structure and function (such as myocardial trabeculae, coronary microvascular anatomy, tissue perfusion, myocyte histology, electrical conduction, heart rate, and blood-pressure variability), fractal analysis is a powerful, but still underused, mathematical tool. In this Perspectives article, we explain some fundamental principles of fractal geometry and place it in a familiar medical setting. We summarize studies in the cardiovascular sciences in which fractal methods have successfully been used to investigate disease mechanisms, and suggest potential future clinical roles in cardiac imaging and time series measurements. We believe that clinical researchers can deploy innovative fractal solutions to common cardiac problems that might ultimately translate into advancements for patient care

The differential mediating roles of resilience in the relationship between meaningful living and stress among college students during the COVID-19 pandemic

The current literature, mostly Euro-American based, indicates that the presence of meaning in life (MIL) improves resilience and lowers stress. However, the differential mediating roles of resilience in the relationship between the search for and presence of MIL, and stress have not been explored. This study aimed to investigate the differential mediating roles of resilience in the relationship between the presence of and search for MIL, and stress among Omani college students amid the COVID-19 pandemic. This cross-sectional study consisted of the Brief Resilience Scale, Perceived Stress Scale 4, and Meaning in Life Questionnaire, as well as socio-demographic questions. A path analysis model was used to examine the hypothesis. A total of 970 Omani college students responded to the questionnaire. Findings indicate that searching for MIL was significantly associated with a high level of stress directly (β = 0.023; p < 0.001) and indirectly, through a negative effect on resilience (β =  0.006; p < 0.001). Conversely, the presence of MIL was significantly associated with a decreased level of stress directly (β = − 0.045; p < 0.001) and indirectly via a positive effect on resilience (β = − 0.151; p < 0.001). In keeping with the proposed hypothesis, this study contributes to the current knowledge, by extrapolating the effect of searching for MIL on resilience and stress, and culturally re-contextualizing MIL research. University counseling centers could adopt meaning-based strategies to mitigate stress by promoting meaningful living and resilience

Ethical Dimensions of the Information Society

Internet users\u27 behaviors are dependent on their ethical dimensions. But ethics are quite relative concepts and they have dimensionality over culture, situation, and personal interests. Due to the various ethical dimensions, conflicts arise at an individual level, collective level, and societal level. In this paper, such ethical dimensions in the information society are discussed in the context of conflict dynamics, and how the conflicts affect our societies

The expert system is aimed at novice technicians who know how to operate the machines but have not acquired the decision making skills that are gained with experience. This paper describes the domain background and the stages of development of the expert system

The Frequency of Neuropsychiatric Sequelae After Traumatic Brain In-jury in the Global South: A systematic review and meta-analysis

Countries in the 'global south' are characterized by factors that contribute to the increased incidence of traumatic brain injury (TBI). This systematic review and meta-analysis aimed to assess the prevalence of neuropsychiatric sequelae following a TBI, specifically among the Western Asian, South Asian, and African regions of the global south. A literature review was conducted until August 20, 2021, for publications that measured psychiatric or cognitive impairment after TBI from the 83 countries that constitute the aforementioned regions. The main databases, such as PsycINFO, Scopus, PubMed/MEDLINE, ProQuest (English), Al-Manhal (Arabic) and Google Scholar, were selected for grey literature. Following the evaluation of the articles using the Joanna Briggs Institute guidelines, the random effects model was used to estimate the prevalence of depression, anxiety, posttraumatic stress disorders (PTSD), sleep disturbance related to TBI (TBI-SD), obsessive–compulsive disorder (OCD), and cognitive impairment. Of 56 non-duplicated studies identified by the initial search, 27 studies were eligible for systematic review and 23 for meta-analysis. The pooled prevalence of depression in a total sample of 1882 was 35·35% (95% CI=24·64–46·87%), of anxiety in a total sample of 1211 was 28·64% (95% CI=17·99–40·65%), of PTSD in a total sample of 426 was 19·94% (95% CI=2·35–46·37%), of OCD in a total sample of 313 was 19·48% (95% CI=0·23–58·06%), of TBI–SD in a total sample of 562 was 26·67% (95% CI=15·63–39·44%), and cognitive impairment in a total sample of 941 was 49·10% (95% CI=31·26–67·07%). To date, this is the first critical review that has examined the spectrum of post–TBI neuropsychiatric sequelae in the specified regions. While existing studies lack homogeneous data due to variability in the diagnostic tools and outcome measures utilised, the reported prevalence rates are significant and comparable to statistics from the global north.
