Visceral Fat Quantified by a Fully Automated Deep-Learning Algorithm and Risk of Incident and Recurrent Diverticulitis.

BACKGROUND: Obesity is a risk factor for diverticulitis. However, it remains unclear whether visceral fat area, a more precise measurement of abdominal fat, is associated with the risk of diverticulitis. OBJECTIVE: To estimate the risk of incident and recurrent diverticulitis according to visceral fat area. DESIGN: A retrospective cohort study. SETTINGS: The Mass General Brigham Biobank. PATIENTS: A total of 6654 patients who underwent abdominal CT for clinical indications and had no diagnosis of diverticulitis, IBD, or cancer before the scan were included. MAIN OUTCOME MEASURES: Visceral

Tofacitinib Is Associated With Increased Risk of Postoperative Venous Thromboembolism in Patients With Ulcerative Colitis.

BACKGROUND: In 2019, the Food and Drug Administration issued a black box warning for increased risk of venous thromboembolism in patients with rheumatoid arthritis exposed to tofacitinib. There are limited data regarding postoperative venous thromboembolism risk in patients with ulcerative colitis exposed to tofacitinib. OBJECTIVE: To assess whether preoperative exposure to tofacitinib is associated with increased odds of postoperative venous thromboembolism. DESIGN: Retrospective review. SETTINGS: Tertiary academic medical center. PATIENTS: Consecutive patients exposed to tofacitinib with

Impact of Preoperative Factors in Patients With IBD on Postoperative Length of Stay: A National Surgical Quality Improvement Program-Inflammatory Bowel Disease Collaborative Analysis.

BACKGROUND: Patients with IBD are challenging to manage perioperatively because of disease complexity and multiple comorbidities. OBJECTIVE: To identify whether preoperative factors and operation type were associated with extended postoperative length of stay after IBD-related surgery, defined by 75th percentile or greater (n = 926; 30.8%). DESIGN: This was a cross-sectional study based on a retrospective multicenter database. SETTING: The National Surgery Quality Improvement Program-Inflammatory Bowel Disease Collaborative captured data from 15 high-volume sites. PATIENTS: A total of 3008

The Microbiome of Complicated Diverticulitis: An Imbalance of Sulfur-Metabolizing Bacteria.

BACKGROUND: The progression to acute diverticulitis from the relatively benign condition of colonic diverticulosis is not well characterized. A smaller subset may even develop complicated (perforated) diverticulitis resulting in sepsis and/or death. Characterizing the differences between recurrent, uncomplicated diverticulitis, and the more virulent, complicated diverticulitis is necessary to guide clinical decision-making. Alterations to the microbiome offer a possible explanation for local inflammation and the pathophysiology of diverticular disease. OBJECTIVE: This study aimed to character

Recommendations for Optimal Endoscopic Localization of Colorectal Neoplasms: A Delphi Consensus of National Experts.

BACKGROUND: Colonoscopy is the standard of care for diagnosis and evaluation of colorectal cancers before surgery. However, varied practices and heterogenous documentation affects communication between endoscopists and operating surgeons, hampering surgical planning. OBJECTIVE: This study aimed to develop recommendations for the use of standardized localization and reporting practices for colorectal lesions identified during lower GI endoscopy. DESIGN: A systematic review of existing endoscopy guidelines and thorough narrative review of the overall endoscopy literature were performed to iden

[Correlation between survival time and severity of injuries in fatal injuries in traffic accidents].

INTRODUCTION: In forensic pathology, only trauma systems based on disintegration of anatomic structure of organs and tissues, could be used for objectivization, comparison and establishing of severity of injuries. Trauma systems based on pathophysiological values are useless. The Abbreviated Injury Scale (AIS) and its derivate Injury Severity Score (ISS) are the most common. AIS coded injuries are divided into six body regions and injuries are assigned a six-digit score in relation to their severity. ISS results the sum of the squares of the highest AIS values from the three most severely inju

Physiological adaptation of maternal plasma volume during pregnancy: a systematic review and meta-analysis.

OBJECTIVE: To describe the physiological pattern of gestational plasma volume adjustments in normal singleton pregnancy and compare this with the pattern in pregnancies complicated by pregnancy-induced hypertension, pre-eclampsia or fetal growth restriction. METHODS: We performed a meta-analysis of the current literature on plasma volume adjustments during physiological and complicated pregnancies. Literature was retrieved from PubMed (NCBI) and EMBASE (Ovid) databases. Included studies reported both reference plasma volume measurements (non-pregnant, prepregnancy or postpartum) and measureme

Multiple myelomas in cats.

Multiple myelomas are uncommon neoplasms of the bone marrow of cats [Weber NA, Tebeau CS (1998) An unusual presentation of multiple myeloma in two cats. Journal of the American Animal Hospital Association34 (6), 477-483]. Nine cats diagnosed with multiple myelomas were retrospectively identified over a 16-year period (1986-2002). Cats with multiple myelomas were older than 7 years (mean age 11.7 years); six males and three females were affected (2.1), but no breed predisposition was evident. Treatment of multiple myelomas consisted of supportive management in the nine cats and anti-neoplastic

Clinical and Genomic Epidemiology of Carbapenem-Nonsusceptible Citrobacter spp. at a Tertiary Health Care Center over 2 Decades.

Carbapenem-nonsusceptible Citrobacter spp. (CNSC) are increasingly recognized as health care-associated pathogens. Information regarding their clinical epidemiology, genetic diversity, and mechanisms of carbapenem resistance is lacking. We examined microbiology records of adult patients at the University of Pittsburgh Medical Center (UMPC) Presbyterian Hospital (PUH) from 2000 to 2018 for CNSC, as defined by ertapenem nonsusceptibility. Over this time frame, the proportion of CNSC increased from 4% to 10% (P = 0.03), as did daily defined carbapenem doses/1,000 patient days (6.52 to 34.5; R2 =

Epigenetic Activation of CCDC183-AS1 Promotes Osteoclastogenesis and Prostate Cancer Bone Metastasis Through the FUBP1/LIGHT Axis.

Bone metastasis (BM) is a major contributor to poor prognosis of prostate cancer (PCa); however, the underlying mechanisms of PCa BM remain poorly understood. A better understanding of these processes may provide critical insights for developing effective preventive and therapeutic strategies for PCa BM. In this study, significant upregulation of CCDC183-AS1 in PCa BM is identified, which is associated with disease progression. CCDC183-AS1 overexpression enhanced the ability of PCa cells to spread to the bone by inducing osteoclastogenesis and aiding in the creation of a BM niche. Mechanistica

[Therapeutic alternatives for drug-associated maxillary osteonecrosis (MRONJ): reports of two clinical cases and review of the literature].

INTRODUCTION: Drug-associated Maxillary Osteonecrosis is one of the most relevant adverse effects in treatment with antiresorptive drugs such as bisphosphonates and denosumab. Oncological conditions such as multiple myeloma, breast cancer, prostate, and bone-metabolic disorders such as osteoporosis lead the indications for these antiresorptive therapies. Treatment is complex because the disease is often refractory. Pharmacological, conservative and surgical treatments are described. OBJECTIVE: The aim of this study is to report two clinical cases of MRONJ treated with two different therapeuti
