BACKGROUND: We compared Kaposi sarcoma (KS) risk in adults who started antiretroviral therapy (ART) across the Asia-Pacific, South Africa, Europe, Latin, and North America. METHODS: We included cohort data of human immunodeficiency virus (HIV)-positive adults who started ART after 1995 within the framework of 2 large collaborations of observational HIV cohorts. We present incidence rates and adjusted hazard ratios (aHRs). RESULTS: We included 208140 patients from 57 countries. Over a period of 1

The Adhere4U application did not improve adherence to immunosuppressive therapy. Our evidence is limited by the high rate of attrition. Further studies on strategies to facilitate patient engagement with mobile interventions are warranted.

For the modern practice of cancer surgery, the concept of oncovascular surgery (OVS), defined as cancer resection with concurrent ligation or reconstruction of a major vascular structure, can be very important. OVS for advanced cancers requires specialized procedures performed by a specialized multidisciplinary team. Roles of oncovascular surgeons are summarized as: a primary surgeon in vesselorigin tumors, a rescue surgeon treating complications during cancer surgery, and a consultant surgeon a

This study analyzed the association between medication adherence and the intrapatient variability (IPV) of tacrolimus concentrations among kidney transplant recipients through a post hoc analysis of the dataset from a recently conducted randomized controlled trial. Among 138 patients enrolled in the original trial, 92 patients with ≥ 5 months of medication event monitoring system (MEMS) use and ≥ 4 tacrolimus trough values were included in this post hoc analysis. The variability of tacrolimus tr

The identification rate of SLNB and the accuracy of intraoperative frozen section examination after NAC are comparable to the results without NAC in patients with early breast cancer. However considering the high false negative rates, general application of SLNB after NAC should be avoided. Patients with progesterone-positive tumors and non-triple-negative breast cancers may be a select group of patients in whom SLNB can be employed safely after NAC, but further studies are necessary.

BACKGROUND: Segmental arterial mediolysis (SAM) is a rare non-atherosclerotic, non-inflammatory vascular disorder varying widely in clinical course. The purpose of this study is to analyze detailing clinical and imaging manifestations over time in patients with SAM through a literature review and to suggest an optimal management strategy. METHODS: A retrospective review of eight consecutive patients diagnosed with SAM between January, 2000 and January, 2012 was conducted. All presented with acut

Background and objectives Use of arteriovenous fistulas, the most preferred type of access for hemodialysis, is limited by their high maturation failure rate. The aim of this study was to assess whether aggressive surveillance with routine duplex ultrasound and intervention can decrease the maturation failure rate of arteriovenous fistulas. Design, setting, participants, & measurements We conducted a single–center, parallel–group, randomized, controlled trial of patients undergoing autogenou

We have shown that mouse liver contains enzymes that catalyze the conversion of the ketol side chain to the 20-hydroxy-21-oic acid side chain. In this paper, we have studied the oxidative metabolism of corticosterone to acidic end products in intact mice. A significant fraction of radioactivity from intraperitoneal injections of [4-14C]corticosterone appeared in liver and intestine within 5 min. The major steroid in liver at 5 min postinjection was found to be corticosterone, although acidic met

Purpose: Sentinel lymph node biopsy (SLNB) is an accurate andeffective means of axillary nodal staging in early breast cancer. However its indication after neoadjuvant chemotherapy (NAC) isunder constant debate. The present study evaluates the reliabilityof SLNB in assessing axillary nodal status after NAC. Methods:Data from 281 patients who had received NAC and subsequentSLNB were reviewed. The identification and false negative ratesof SLNB were determined and the clinicopathologic factors asso

Horseshoe kidney (HSK) is the most common congenital abnormality of the urologic system encountered during abdominal aortic aneurysm (AAA) surgery. Here, the authors report a case of AAA coexisting with HSK that was successfully treated by open surgery. Two accessory renal arteries of 2.5 mm and 3.1 mm were reimplanted. One of the implanted arteries later occluded and infarct of the isthmus developed, but there was no impairment of renal function. The authors discuss the complexity of the surgic

Traumatic dissection of the celiac artery without aortic dissection is a rare event. Here we describe two cases of celiac artery dissection after blunt abdominal trauma managed conservatively without surgical or endovascular intervention. Keywords: Celiac artery; Vascular system injuries; Abdominal injuries

Background: Whether anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody levels post-third coronavirus disease (COVID-19) vaccination correlate with worse outcomes due to breakthrough infection is unclear. We evaluated the association between anti-SARS-CoV-2 antibody levels and symptomatic breakthrough infection or hospitalization during the Omicron surge in kidney transplant recipients. Methods: In total, 287 kidney transplant recipients expected to receive a third vaccina

BACKGROUND: We aimed to assess whether patients colonized with certain organisms in the genitourinary tract would have greater urinary tract infection (UTI) risk during the post-transplantation period, and whether information on the perioperatively colonized organisms may help identify the causal organisms during early UTI. METHODS: We retrospectively reviewed the culture results of preoperative urine, preoperative urethral swab, and postoperative urinary catheter tip specimens of 420 renal tran
