Developing novel indoles as antitubercular agents and simulated annealing-based analysis of their binding with MmpL3.

Aim: This research aimed to develop novel indole-2-carboxamides as potential antitubercular agents using rational drug design. It also focused on identifying the critical interactions required for these compounds to exhibit effective antitubercular activity.

Materials And Methods: Novel indole-2-carboxamides targeting MmpL3 were designed based on SAR, synthesized, and tested for their antitubercular and induction properties.

Assessment of the impact of the COVID-19 pandemic on the productivity of teaching hospitals in Brazil.

Objectives: To analyze the influence of the COVID-19 pandemic on the productivity of general teaching hospitals in Brazil, by region and legal entity, and to propose parameters of care.

Methods: This was an observational study by means of mathematical modeling with data envelopment analysis and Malmquist index, using data on inputs and healthcare output before (2019) and during (2021) the pandemic.

Results: A total of 149 general teaching hospitals were analyzed, 32 of which were considered efficient.

Three-year survival follow-up of patients with gastrointestinal cancer treated during the COVID-19 pandemic in Spain: data from the PANDORA-TTD20 study.

Introduction: The initial SARS-CoV-2 pandemic wave in Spain in 2020 precipitated significant paradigm shifts in gastrointestinal oncology patient management. This study captures the "Zeitgeist" of this period by analyzing adaptive strategies, treatment modifications, and survival outcomes, leveraging a 3-year follow-up perspective to extract insights from this unprecedented experience.

Methods: We conducted a multicenter, retrospective cohort study utilizing the RETUD-TTD registry, encompassing 703 patients across 19 Spanish centers in April 2020.

Complete versus culprit-only coronary revascularization in patients with myocardial infarction and multivessel disease undergoing percutaneous coronary intervention: an updated meta-analysis.

Introduction: Recently, the FFR-Guidance for Complete Nonculprit Revascularization (FULL REVASC) trial in ST elevation myocardial infarction (STEMI) patients with multiple vessel disease (MVD) did not show differences in the composite endpoint of death from any cause, myocardial infarction, or unplanned revascularization than culprit-lesion-only percutaneous coronary intervention (PCI) at 4.8 years, although complete revascularization is a recommendation IA in current guidelines. We want to determine through an updated meta-analysis whether complete revascularization is associated with decreased mortality and hard clinical endpoints compared to culprit lesion only PCI.

Pallidal circuits drive addiction behavior.

Understanding the neural mechanisms that control addiction processes, including drug-seeking and relapse, is key to finding new targets for substance use disorder (SUD) pharmacotherapies and circuit-based therapies. Addictive drugs alter activity in distinct neural circuits that can lead to SUD symptoms, including compulsive drug craving and taking. This includes the pallidum, a region in the basal ganglia that acts as an integrator of associative, sensorimotor, and limbic information to shape motor responses, promote reward-learning, and regulate habit formation.
