The Association Between Sex and Survival for Anal Squamous Cell Carcinoma.

Background: The incidence of anal squamous cell carcinoma (SCC) is rising, despite the introduction of a vaccine against human papillomavirus (HPV), the most common etiology of anal SCC. The rate of anal SCC is higher among women and sex-based survival differences may exist. We aimed to examine the association between sex and survival for stage I-IV anal SCC.

Survival Outcomes for Malignant Peritoneal Mesothelioma at Academic Versus Community Hospitals.

Background: Malignant peritoneal mesothelioma is a rare disease with poor outcomes. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the cornerstone of therapy. We aim to compare outcomes of malignant peritoneal mesothelioma treated at academic versus community hospitals.

Management of Nonoperative Diverticulitis : Is Surgical Admission Always Best?

Background: Institutional pathways (IPs) allow efficient utilization of health care resources. Recent literature reports decreased hospital length of stay (LOS), complications, and costs with the admittance of surgical disease to surgical services. Our study aimed to demonstrate that admission to surgery for nonoperative, acute diverticulitis reduces hospital LOS, and cost, with comparable complication rates.

Resource utilization of adult patients referred to the emergency department from an urgent care center.

Background: The rise of urgent care centers (UCC) continues to serve as an alternative to emergency departments (ED) for patients with a perceived lower acuity complaint. Patients that are deemed to be higher acuity are often evaluated at an UCC and then redirected to EDs. However, limited data exist on resource utilization by patients who are transferred from UCCs to EDs.

A NSQIP analysis of trends in surgical outcomes for rectal cancer: What can we improve upon?

Background: There is significant variation in rectal cancer outcomes in the USA, and reported outcomes have been inferior to those in other countries. In recognition of this fact, the American College of Surgeons (ACS) recently launched the Commission on Cancer (CoC) National Accreditation Program for Rectal Cancer (NAPRC) in an effort to further optimize rectal cancer care. Large surgical databases will play an important role in tracking surgical and oncologic outcomes.

IFN-γ and IL-17A regulate intestinal crypt production of CXCL10 in the healthy and inflamed colon.

During intestinal inflammation, immature cells within the intestinal crypt are called upon to replenish lost epithelial cell populations, promote tissue regeneration, and restore barrier integrity. Inflammatory mediators including T1/T17-associated cytokines influence tissue health and regenerative processes, yet how these cytokines directly influence the colon crypt epithelium and whether the crypt remains responsive to these cytokines during active damage and repair, remain unclear. Here, using laser-capture microdissection and primary colon organoid culture, we show that the cytokine milieu regulates the ability of the colonic crypt epithelium to participate in proinflammatory signaling.

DNA damage response genes mark the early transition from colitis to neoplasia in colitis-associated colon cancer.

Chronic intestinal inflammation predisposes patients with Inflammatory Bowel Disease (IBD) to Colitis-Associated Cancer (CAC). In the setting of chronic inflammation, microsatellite instability (MSI) results from early loss of DNA damage response (DDR) genes, ultimately leading to tumor formation. Despite continued efforts to improve early detection of high risk, pre-dysplastic regions in IBD patients, current macroscopic and genetic surveillance modalities remain limited.

Revisiting endotracheal self-extubation in the surgical and trauma intensive care unit: Are they all fine?

Objectives: Endotracheal self-extubation (ESE) is a serious health care concern. We designed this study to test our hypothesis that not all patients with ESE are successful in spontaneous breathing and reintubation has negative impact on outcomes.

Methods: Data on all 39 patients of ESE in our surgical and trauma intensive care unit (ICU) in 2012 were prospectively collected and retrospectively analyzed.

The coenzyme A disulphide reductase of Borrelia burgdorferi is important for rapid growth throughout the enzootic cycle and essential for infection of the mammalian host.

In a microarray analysis of the RpoS regulon in mammalian host-adapted Borrelia burgdorferi, bb0728 (cdr) was found to be dually transcribed by the sigma factors σ(70) and RpoS. The cdr gene encodes a coenzyme A disulphide reductase (CoADR) that reduces CoA-disulphides to CoA in an NADH-dependent manner. Based on the abundance of CoA in B.

Intra-articular corticosteroid injection for the treatment of idiopathic adhesive capsulitis of the shoulder.

Treatment for idiopathic adhesive capsulitis or frozen shoulder of the shoulder is controversial. The hypothesis of the study is that intra-articular corticosteroid injection in the early stages of idiopathic adhesive capsulitis will lead to a rapid resolution of stiffness and symptoms. This is a retrospective cohort study of only patients with stage 1 or stage 2 adhesive capsulitis.

Ambulatory dysfunction due to unrecognized pernicious anemia.

Pernicious anemia can result in significant hematologic and neurologic impairments due to a reduction in cobalamin absorption. Typically thought to be a disease of elderly whites, a growing body of literature has documented the disease in blacks and in younger age groups. We describe a case of a young black woman with gradually progressive lower extremity paresthesias, weakness, and ataxia as the primary presenting symptoms of pernicious anemia.
