Choice of species affects phylogenetic stability of deep nodes: an empirical example in Terrabacteria.

Motivation: The promise of higher phylogenetic stability through increased dataset sizes within tree of life (TOL) reconstructions has not been fulfilled. Among the many possible causes are changes in species composition (taxon sampling) that could influence phylogenetic accuracy of the methods by altering the relative weight of the evolutionary histories of each individual species. This effect would be stronger in clades that are represented by few lineages, which is common in many prokaryote phyla.

Dysphagia: An Unusual Presentation of Metastatic Uterine Cervical Carcinoma.

Worldwide, cervical cancer is the third most common cancer among women and the fourth leading cause of death from cancer. The most common sites of metastasis are the pelvic lymph nodes, vagina, and the pelvic sidewalls. Distant metastases are uncommon but can involve the bone, lung, and liver.

Natural language processing as an alternative to manual reporting of colonoscopy quality metrics.

Background And Aims: The adenoma detection rate (ADR) is a quality metric tied to interval colon cancer occurrence. However, manual extraction of data to calculate and track the ADR in clinical practice is labor-intensive. To overcome this difficulty, we developed a natural language processing (NLP) method to identify adenomas and sessile serrated adenomas (SSAs) in patients undergoing their first screening colonoscopy.

Transnasal PEG tube placement in patients with head and neck cancer.

Background: Head and neck cancer (H&NCa) patients have an increased risk of malnutrition and dysphagia because of their malignancy and the adverse events of therapy. Most of these patients require gastrostomies. Four percent to 7% of H&NCa patients are unable to undergo per oral percutaneous gastrostomies.

Percutaneous endoscopic gastrostomy in cancer patients: predictors of 30-day complications, 30-day mortality, and overall mortality.

Background: Cancer patients benefit from percutaneous endoscopic gastrostomy (PEG) in many ways including nutritional support and venting in cases of malignant obstruction. Lack of high-quality studies with adequate follow-up has led to limited information regarding risk stratification and predictors of morbidity and mortality.

Aims: Elucidate predictors of complications and mortality with long-term follow-up in cancer patients undergoing PEG.
