Complex bacterial diversity of Guaymas Basin hydrothermal sediments revealed by synthetic long-read sequencing (LoopSeq).

Hydrothermal sediments host phylogenetically diverse and physiologically complex microbial communities. Previous studies of microbial community structure in hydrothermal sediments have typically used short-read sequencing approaches. To improve on these approaches, we use LoopSeq, a high-throughput synthetic long-read sequencing method that has yielded promising results in analyses of microbial ecosystems, such as the human gut microbiome.

Cancer outcomes and cardiopulmonary toxicities for black patients with breast cancer treated with proton therapy.

Background: Black women have a 40% higher breast cancer (BC) mortality rate than White women and are at a higher risk of acquiring cardiovascular disease. Proton therapy (PT) can be used to mitigate cardiac radiation exposure; however, PT remains a scarce resource in the United States. We report on the cardiovascular profiles of patients undergoing PT to determine the potential benefit of PT for Black women when compared to non-Black patients.

A global comparison of surface and subsurface microbiomes reveals large-scale biodiversity gradients, and a marine-terrestrial divide.

Subsurface environments are among Earth's largest habitats for microbial life. Yet, until recently, we lacked adequate data to accurately differentiate between globally distributed marine and terrestrial surface and subsurface microbiomes. Here, we analyzed 478 archaeal and 964 bacterial metabarcoding datasets and 147 metagenomes from diverse and widely distributed environments.

Hepato-Pancreato-Biliary Surgery: Analysis of Outcomes Among Graduates of Different Fellowship Pathways.

Objective: To characterize the association between type of fellowship training and patient outcomes following hepatopancreatic (HP) surgery across different surgeon career stages using a national representative cohort of Medicare beneficiaries.

Background: The current state of training in HPB surgery in North America is defined through three main pathways: the Complex General Surgical Oncology (CGSO), the Americas HPB Association fellowship, and the American Society of Transplant surgeons fellowship. Each pathway offers a unique perspective on HPB surgery with different number of training years, yet outcomes of graduates performing HP surgery relative to type of fellowship training have not been defined.
