Lockdown is an important measure that has been globally adopted to reduce the spread of the contagious disease caused by SARS CoV-2. The imposed schedule and confinement led to extensive use of digital media and rise in sedentary activity drastically. The escalated duration of screen exposure causes disruption in sleep behavior. An online survey was conducted to comprehend the effect of lockdown on sleep behavior and screen exposure time on school children. Screen exposure time involved with various electronic gadgets was also analyzed. It was observed that the social jet lag and sleep debt were significantly less during lockdown than before it. Inertia during lockdown significantly increased. The difference between screen exposure time on weekdays before lockdown and weekends during lockdown was identified to be the highest. Three clusters based on sleep behavior and duration of screen time were identified of which Cluster 2 revealed simultaneous existence of high sleep duration and screen time. These baseline data on sleep parameters and duration of exposure to the screen will help us in devising approaches to mitigate the evident disruption this unprecedented phase has brought about.

High Alt Med Biol. 17:294-299, 2016.-Treatment strategies for management of high-altitude pulmonary edema (HAPE) are mainly based on the observational studies with only two randomized controlled trials, thus the practice is very heterogeneous and individualized as per the choice of treating physician. To compare the response to different modalities of therapy in patients with HAPE in a randomized controlled manner. We conducted an open-label, randomized noninferiority trial to compare three modalities of therapy (Therapy 1: supplemental O with oral dexamethasone 8 mg q8 hours [n = 42], Therapy 2: supplemental O with sustained release oral nifedipine 20 mg q8 hours [n = 41], and Therapy 3: only supplemental O [n = 50]). Bed rest was mandated in all patients. The study was conducted in a cohort of previously healthy young lowlander males at an altitude of 3500 m. Baseline characteristics of the patients were comparable in the study arms. Complete response was defined as clinical and radiological resolution of features of HAPE, no oxygen dependency, a normal 6-minute walk test (6MWT) on 2 consecutive days, and normal two-dimensional echocardiography. Results were compared by analysis of variance using SPSS version 16.0. There was no statistical difference in duration of therapy to complete response between the three groups (Therapy 1: 8.1 ± 4.0 days, Therapy 2: 6.7 ± 3.9 days, Therapy 3: 6.8 ± 3.2 days; p = 0.15). There were no deaths in any of the groups. We conclude that oxygen and bed rest alone are adequate therapy for HAPE and that adjuvant pharmacotherapy with either dexamethasone or nifedipine does not hasten recovery.

Background: To combat the COVID-19 pandemic, several countries imposed strict lockdown to ensure social distancing to limit the spread of the virus. This caused difficulties in the management and care of patients with various chronic disorders including dementia. Objectives: The objective of the study was to explore the health condition of patients with dementia and assess their caregivers’ burden during the lockdown. Methods: A total of 57 caregivers of patients with dementia who had attended the cognitive clinic of the institute for a follow-up within 1 year preceding the lockdown were assessed through telephonic interviews. Caregivers’ details were noted following an interview related to the patients’ health condition during lockdown and caregiver concerns. Results: Findings showed a deterioration in memory in 66.7% of patients with dementia and an increase in symptoms like agitation, sleeplessness, low mood, restlessness, aggression, etc., Caregivers felt helpless and had to manage new concerns and they were not sure as to how to deal with the situation. Conclusion: The lockdown situation disrupted the health conditions of dementia patients and caregivers faced novel challenges while managing them.
