Objective: The primary aim of this study is to identify the needs of caregivers who are primarily responsible for caring for their children during the transition from the hospital.

Methodology: A needs assessment survey was conducted among 30 mothers whose children were admitted to the paediatric medicine ward at the All India Institute of Medical Sciences, Bhubaneswar. The researcher utilized a semi-structured questionnaire alongside unstructured discussions to assess the needs and barriers faced by caregivers during hospital transitions.

The first FDA approved, MDR-TB inhibitory drug bedaquiline (BDQ), entraps the c-ring of the proton-translocating F region of enzyme ATP synthase of , thus obstructing successive ATP production. Present-day BDQ-resistance has been associated with cardiotoxicity and mutation(s) in the atpE gene encoding the c subunit of ATP synthase (ATPc) generating five distinct ATPc mutants: Ala63→Pro, Ile66→Met, Asp28→Gly, Asp28→Val and Glu61→Asp. We created three discrete libraries, first by repurposing bedaquiline via scaffold hopping approach, second one having natural plant compounds and the third being experimentally derived analogues of BDQ to identify one drug candidate that can inhibit ATPc activity more efficiently with less toxic properties.

Introduction: Robust connections have been identified between the pathophysiology of mental disorders and the functioning of the circadian system. The overarching objective of this study was to investigate the potential for circadian rhythms to be leveraged for therapeutics in mental disorders.

Methods: We considered two approaches to chronotherapy-optimal timing of existing medications ("clocking the drugs") and redressing circadian abnormalities with small molecules ("drugging the clock").

Background: Peripheral oxygen saturation (SpO) above 94% is typical in children in paediatric intensive critical care units (PICUs) who are receiving invasive ventilation and supplemental oxygen. In a previous report from the Oxy-PICU trial, we showed that lower (conservative) oxygenation targets (SpO 88-92%) are beneficial, showing small but statistically significant differences in duration of organ support and large but non-significant cost reductions at 30 days. In this pre-specified analysis of the Oxy-PICU trial, we compare longer-term outcomes and cost-effectiveness of conservative versus liberal (SpO >94%) oxygenation targets in children with emergency PICU admission.

Background: Accumulation of malignant plasma cells in the bone marrow causes lytic bone lesions in 80% of multiple myeloma patients. Frequently fracturing, they are challenging to treat surgically. Myeloma cells surviving treatment in the presumably protective environment of bone lesions impede their healing by continued impact on bone turnover and can explain regular progression of patients without detectable minimal residual disease (MRD).
