The utility of PET imaging in depression.

This educational review article aims to discuss growing evidence from PET studies in the diagnosis and treatment of depression. PET has been used in depression to explore the neurotransmitters involved, the alterations in neuroreceptors, non-neuroreceptor targets (e.g., microglia and astrocytes), the severity and duration of the disease, the pharmacodynamics of various antidepressants, and neurobiological mechanisms of non-pharmacological therapies like psychotherapy, electroconvulsive therapy, and deep brain stimulation therapy, by showing changes in brain metabolism and receptor and non-receptor targets. Studies have revealed alterations in neurotransmitter systems such as serotonin, dopamine, GABA, and glutamate, which are linked to the pathophysiology of depression. Overall, PET imaging has furthered the neurobiological understanding of depression. Despite these advancements, PET findings have not yet led to significant changes in evidence-based practices. Addressing the reasons behind inconsistencies in PET imaging results, conducting large sample size studies with a more standardized methodological approach, and investigating further the genetic and neurobiological aspects of depression may better leverage PET imaging in future studies.

Weighted Blanket Therapy for Periodic Limb Movement Disorder: A Case Report Highlighting Improved Sleep Quality and Reduced Symptoms.

This case report describes a 20-year-old female patient with periodic limb movement disorder (PLMD), who experienced trouble sleeping and daytime fatigue. Polysomnography revealed frequent non-arousing periodic limb movements and a high PLMD index. The patient was advised on non-pharmacological interventions, including the use of weighted blankets, sleep hygiene education, and lifestyle modifications. At the six-week follow-up, the patient reported significant improvement in symptoms. The case report highlights the potential effectiveness of non-pharmacological interventions in managing PLMD and emphasizes the need for a multidisciplinary approach to improve patient outcomes and quality of life. Further research is required to determine the long-term efficacy and safety of these interventions. The psychological impact of PLMD on the patient's social life and academic performance is also discussed. The management of sleep disorders should involve a multidisciplinary approach to improve patient outcomes and quality of life.

Secondary Prevention of Rheumatic Heart Disease in Nepal: Are We Going Backward?

A secondary level of prophylaxis has proven to be the most successful in Nepal, a country with an endemic rate of rheumatic heart disease, in combating the severe issues associated with rheumatic heart disease. The use of benzathine penicillin G in secondary prophylaxis of rheumatic heart disease, recommended by several guidelines, has been increasingly abandoned in Nepal due to a lack of national guidelines and the termination of the prior programs. The use of oral penicillin and alternative oral antibiotics, which are less effective in preventing the recurrence of acute rheumatic fever, is on the rise. Nepal urgently needs to develop new national guidelines and ensure their effective implementation in order to slow the increase in the number of rheumatic heart disease patients. In this article, we explore the limitations, challenges, and advantages of using the consensus-supported intramuscular benzathine penicillin G as the first-line drug for the secondary prevention of rheumatic heart disease.

Composite Anxiety-depression among Medical Undergraduates during COVID-19 Pandemic in a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

INTRODUCTION: Fear and anxiety is a natural response during crisis. From constant worry of getting infected, death of loved ones, transitioning of lifestyle to loss of social connection; there can be several psychological triggers. The effect on mental health on the general population could be greater than those affected by the infection itself during the pandemic. Among medical students, who already have several other psychological afflictions, these triggers might be detrimental. Hence, this study aims to find out the prevalence of composite anxiety-depression among medical undergraduates in a tertiary care hospital. METHODS: A descriptive cross-sectional study was conducted among medical undergraduates in a tertiary care hospital from 20th December 2020 to 5th January 2021. Ethical approval was taken from the Institutional Review Committee. The sample size was calculated and convenient sampling was done. The data were entered in International Business Machines Statistical Package for Social Sciences version 20.0. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of 315 participants on the Patient Health Questionnaire-Anxiety and Depression Scale, severe composite anxiety-depression was seen in 10 (3.17%) at 95% Confidence Interval (1.23-5.1) participants, moderate in 35 (11.11%) at 95% Confidence Interval (7.63-14.58) and mild in 98 (31.11%) at 95% Confidence Interval (25.99-36.22). And 172 (54.6%) at 95% Confidence Interval (49.1-60) were normal. CONCLUSIONS: The rapid rise of apprehension among people amidst infectious outbreaks can ensue and medical students are no exception. So, at this time of crisis, there is a need to protect their mental health and it should be emphasized and endorsed.
