Background Gallbladder carcinoma (GBC) has deleterious outcomes, but due to its reduced incidence in Western countries, there is a paucity of data on this disease. Here we report the outcomes of a retrospective analysis of resectable gallbladder cancer from a tertiary cancer centre in eastern India. The primary objective of this study is to evaluate the overall survival (OS) and relapse-free survival (RFS) rates among patients with resectable GBC.

The carbon-based nanostructures have led to the development of theranostic nanoplatforms for simultaneous diagnosis and therapy due to their effective cell membrane-penetration ability, low degree of cytotoxicity, excellent pore volume, substantial chemical stability, and reactive surface. In the last few years, extensive efforts were made to design multifunctional nanoplatform strategies based on carbon nanostructures, involving multimodal imaging, controlled drug release capabilities, sensing in vitro, efficient drug loading capacity, and therapy. Carbon and graphene quantum dots (CQDs and GQDs) were the recent entrants, contingently being assessed for drug delivery and bioimaging.

Context: This article presents a theoretical study of three insensitive high explosives based on the FOX-7 moiety. A few heterocyclic five- and six-member nitrogen-rich compounds have been created in an effort to better serve as a potential insensitive high explosive. It has been addressed how these molecules should be optimised in terms of stability, sensitivity, detonation properties, IR frequency computations, formal charge calculations, and more.

Background: Trend analysis of bacteraemias caused by multi-drug resistant (MDR) and extensively drug resistant (XDR) bacteria helps to assess efficacy of infection prevention and control (IPC) practices. Data on the trends of MDR and XDR bacteraemias are lacking from cancer patients in India.

Aims: To report antibiotic resistance rates over time in bacteraemias and to assess the effect of IPC practices where patient isolation facilities were limited on the rates and trends of MDR and XDR bacteraemias from a cancer centre in eastern India.

Background: The north and north-eastern regions of India have among the highest incidence of gallbladder cancer (GBC) in the world. We report the clinicopathological charateristics and outcome of GBC patients in India.

Methods: Electronic medical records of patients diagnosed with GBC at Tata Medical Center, Kolkata between 2017 and 2019 were analyzed.

Purpose: To understand the actual impact of the Covid-19 pandemic and frame the future strategies, we conducted a pan India survey to study the impact on the surgical management of gastrointestinal cancers.

Methods: A national multicentre survey in the form of a questionnaire from 16 tertiary care gastrointestinal oncology centres across India was conducted from January 2019 to June 2021 that was divided into a 15-month pre-Covid era and a similar period of active Covid pandemic era.

Results: There was significant disruption of services; 13 (81%) centres worked as dedicated Covid care centres and 43% reported suspension of essential care for more than 6 months.

Background: The Sustainable Development Goals and the National Health Policy of India aim to reduce premature mortality from noncommunicable diseases (NCD) by one-third in the next decade and by 25% by 2025, respectively. Among NCDs globally, chronic obstructive pulmonary disease (COPD) is a major contributor to death and disability. This underscores the need to understand the burden of COPD at the national level by synthesizing evidence and collating the state-wise COPD data to estimate the prevalence of COPD and to highlight the associated risk factors to inform policymakers.

Transverse colon, owing its origin to midgut and hindgut and harbouring a flexure at both ends, continues to pose a surgical challenge. When compared to the rest of the colon, transverse colon adenocarcinoma is relatively uncommon. These cancers usually present late and lie in close proximity to the stomach, omentum, and pancreas.

In response to Coronavirus 19 pandemic, countries are struggling to contain its spread and save precious human lives. Like others, India is also trying to enhance testing capacity to identify every case and break the chain of transmission. Due to several constrains like geographic distribution of the laboratories, social stigma, prevailing lockdown, people are not being able to seek medical help every time they need.
