Psychological Symptoms of COVID-19 Pandemic Among Community-Dwelling Older People in Oman and Associated Risk Factors.

Introduction: The COVID-19 pandemic has led to a dramatic loss of human lives worldwide. Objective: This study aimed to investigate the psychological factors of the COVID-19 pandemic in the community-dwelling older population. Method: This was a cross-sectional study of older people aged ≥60 years with no mental or psychological illnesses. A total of 193 participants were recruited. The study questionnaire included anxiety- and depression-related questions tailored for the COVID-19 pandemic. The questionnaire was developed through a literature review and expert review. Data was collected from December 2020 to January 2022. Results: The psychological symptoms of COVID-19 were high in this sample (mean 29.18 ± 3.57). Gender (female) was found to have a strong positive relationship with the psychological symptoms of COVID-19 score (p = 0.003). Chronic illnesses (ß = 0.19, p < 0.001), living alone (ß = 0.39, p < 0.001), and having a family member or a friend with COVID-19 (ß = 0.15, p < 0.001) were also found to have a strong positive relationship with the psychological symptoms of COVID-19 score. Conclusion: The negative psychological effects of COVID-19 were high among the older population in Oman. In this study, female gender, chronic illnesses, living alone, and having a family member or a friend with COVID-19 were associated with worse COVID-19 psychological symptoms. Older women were affected by COVID-19 more than older men. In addition, those who had chronic illnesses, lived alone, or had a family member or a friend with COVID-19 were more psychologically burdened by the pandemic than those without those characteristics. Particular attention should be given to older adults who have chronic illnesses, live alone, or have a family member or a friend with COVID-19. Support groups and psychological counseling programs are essential for older people during a pandemic.

Factors Affecting the Willingness to Undertake Premarital Screening Test Among Prospective Marital Individuals.

INTRODUCTION: Awareness toward premarital screening test and its influence on preventing high risk marriages has become a concern to the health care system in Oman. This is due to the increased rates of inherited diseases and genetic disorders among the Omani population secondary to consanguineous marriages. OBJECTIVES: This cross-sectional study aims to describe the utilization of premarital screening tests of selected university study participants as future prospective couples. METHODS: The study included 400 Omani study participants from different majors at a national governmental university that receives students from all over the country. Data was collected using a self-administered questionnaire. RESULTS: Out of the 400 study participants 193 [48.3%] were females and 195 [48.8%] were males, and 380 [95%] were unmarried and 19 [4.8%] were married. Personal and family history of hereditary diseases and consanguinity between parents were reported by 40 participants [10%], 158 [39.5%] and 175 [43.8%] respectively. Three hundred and sixty-one [90.3%] of the total participants were aware of the availability of premarital screening tests in Oman. A total of 357 [89.3%] thought it is necessary to do a premarital screening test and 367 [91.8%] agreed to carry out it in the future. The novel contribution of this manuscript is that our logistic regression showed that people with personal or family history of hereditary disease, and have consanguinity between parents, being a female did not show willingness to undertake the screening while those who are married, have higher GPA, and older supported it. CONCLUSION: Usability of the freely available premarital screening is low despite the study participants awareness and willingness. Future studies should target those who have a history of genetic disease and females as we found them not willing to undertake the test in this study. We also recommend putting in place mandatory rules and regulations for premarital screening tests with better counselling strategies.

Effect of chronic administration and withdrawal of caffeine on motor function, cognitive functions, anxiety, and the social behavior of BLC57 mice.

OBJECTIVES: The cognitive functions, motor coordination, and social behavior were studied in rodents after adding different doses of caffeine in their drinking water. METHODOLOGY: BLC57 mice were divided into four groups: Control (n = 8), chronic moderate dose (n = 8, Ch] MD), Ch high dose (n = 8, Ch HD), and withdrawal (n = 8, WD). Caffeine was administered for 1 month to all groups. Spatial memory was tested by Morris water maze, motor coordination by rotarod (RR), social behavior by (Crawley's test), and anxiety by elevated plus maze (EPM) test. RESULTS: In water maze, the latency to reach the platform was significantly shorter in Ch MD group compared to the control and the Ch HD groups. WD group showed the worst performance. RR results showed that the groups treated with caffeine performed poor in comparison to the control group where their latency to fall was significantly less. In the three-chamber test, the Ch MD group showed enhanced sociability (session 1) and social novelty behavior (session 2). On the other hand, both Ch HD and WD showed a lack in sociability and a deficit in social novelty. In the EPM, results showed that all caffeine administrated mice where more anxious than the control group. CONCLUSION: We concluded that chronic administration of caffeine in MD resulted in enhancement of spatial memory, motor functions, sociability, and social novelty. The anxiety in these animals was, however, increased. On the other hand, Ch HD caffeine had opposite effects on all the parameters except for anxiety.

Acute Administration of Caffeine: The Effect on Motor Coordination, Higher Brain Cognitive Functions, and the Social Behavior of BLC57 Mice.

Excessive caffeine consumption causes adverse health effects. The effects of moderate and high doses of caffeine consumption on the motor coordination, cognitive brain functions, and the social behavior in mice were studied. Animals were divided into three groups: control group, moderate dose group (Ac MD), and high dose group (Ac HD). The animals were tested after 7 days of caffeine administration. A rotarod test for motor coordination showed that the mice of the moderate dose group could stay on the rotating rod longer before falling in comparison to the control group and the high dose group. A water maze test for learning and memory showed better performance of mice receiving the moderate dose of caffeine compared to the other groups. Animals that were administered moderate as well as high doses of caffeine showed no sociability and no preference for social novelty in the three-chamber test used to test social behavior. In an elevated plus maze test, control animals showed no anxiety-like behavior while mice from both of the groups administered with caffeine showed anxiety-like behaviors. Our data conclude that the effects of caffeine on higher brain functions depend on the administration dose. When caffeine was given in moderate doses, it resulted in enhancement of memory and motor coordination functions. However, high doses caused defects in memory and learning. The social behavior of the mice, as determined by the level of anxiety and sociability, was affected negatively by moderate as well as high dose caffeine administration.
