PURPOSE: The aim of this study was to assess the use of recombinant luteinizing hormone (rLH) supplementation in patients who experience a reduction in LH concentration during controlled ovarian hyperstimulation (COH) for IVF/ICSI. METHODS: A multi-center prospective randomized controlled trial (RCT) was performed over three years. Two hundred and forty patients aged between 24 and 42 years undergoing IVF/ICSI treatment with a long down regulation (LDR) protocol were recruited...

BACKGROUND: Renal cell carcinoma (RCC) with isolated lymph node (LN) involvement has historically been associated with poor prognosis. However, a subset of patients may experience long-term survival. OBJECTIVE: To examine the natural history of RCC with isolated LN involvement following surgical resection with long-term follow-up, and to evaluate clinicopathologic features associated with disease progression and survival. DESIGN, SETTING, AND PARTICIPANTS: A total of 138 patients with isolated pN1M0 RCC underwent partial or radical nephrectomy and LN dissection from 1980 to 2010...

A continuous flow extracorporeal ventricular assist device (VAD) was modified to support functionally univentricular infants and children awaiting heart transplantation. A centrifugal VAD, designed to flow from 1.5 to 8 L/min, was used as a bridge-to-transplant in four patients with functionally univentricular circulation. A variable restrictive recirculation shunt permitted lower flow ranges in small patients. In hypoxic patients, an oxygenator was incorporated into the circuit. From 2012 to 2015, the modified VAD was placed in four patients with Glenn physiology...

OBJECTIVES: To describe the epidemiology of extubation failure and identify risk factors for its occurrence in a multicenter population of neonates undergoing surgery for congenital heart disease. STUDY DESIGN: We conducted a prospective observational study of neonates ≤30 days of age who underwent cardiac surgery at 7 centers within the US in 2015. Extubation failure was defined as reintubation within 72 hours of the first planned extubation. Risk factors were identified with the use of multivariable logistic regression analysis and reported as OR with 95% CIs...

This study addresses T-DNA insert stability and transgene expression consistency in multiple cycles of field propagated sugarcane. T-DNA inserts are stable; no transgene rearrangements were observed. AmCYAN1 and PMI protein accumulation levels were maintained. There was no evidence that production of either protein declined across generations and no transgene silencing was observed in three commercial sugarcane varieties through commercially relevant ratooning, propagation-by-setts, and micro-propagation generation processes over 4 years of field testing...

OBJECTIVE: This video article will review the relevant vascular anatomy of the anterolateral thigh flap, describe the CT angiography (CTA) image acquisition, and describe how to report the locations of the perforating arteries along with characteristics that may be important to the surgeon. CONCLUSION: Our method of performing and reporting CTA for patients scheduled to undergo anterolateral thigh flap reconstruction provides a reproducible method of identifying perforating vessels and communicating their location to surgeons...

Swimming animals commonly bend their bodies to generate thrust. For undulating animals such as eels and lampreys, their bodies bend in the form of waves that travel from head to tail. These kinematics accelerate the flow of adjacent fluids, which alters the pressure field in a manner that generates thrust. We used a comparative approach to evaluate the cause-and-effect relationships in this process by quantifying the hydrodynamic effects of body kinematics at the body-fluid interface of the lamprey, Petromyzon marinus, during steady-state swimming...

The United States Food and Drug Administration (FDA) ensures that patients in the U.S. have access to safe and effective medical devices. The Division of Neurological and Physical Medicine Devices reviews medical technologies that interface with the nervous system. This article addresses how to navigate the FDA's regulatory landscape to successfully bring medical devices to patients.

OBJECTIVES: We tested cytoplasmic HuR (cHuR) as a predictive marker for response to chemotherapy by examining tumor samples from the international European Study Group of Pancreatic Cancer-3 trial, in which patients with resected pancreatic ductal adenocarcinoma (PDA) received either gemcitabine (GEM) or 5-fluorouracil (5-FU) adjuvant monotherapy. BACKGROUND: Previous studies have implicated the mRNA-binding protein, HuR (ELAVL1), as a predictive marker for PDA treatment response in the adjuvant setting...

In children with fulminant myocarditis (FM), we sought to describe presenting characteristics and clinical outcomes, and identify risk factors for cardiac arrest and mechanical circulatory support (MCS). A retrospective review of patients with FM admitted at our institution between January 1, 2004, and June 31, 2015, was performed. We compared characteristics and outcomes of FM patients who received cardiopulmonary resuscitation (CPR) and/or were placed on MCS (CPR/MCS group) to those who did not develop these outcomes (Control group)...

Activation of immune cells (but not B cells) with lectins is widely known. We used the structurally defined interaction between influenza hemagglutinin (HA) and its cell surface receptor sialic acid (SA) to identify a B cell receptor (BCR) activation modality that proceeded through non-cognate interactions with antigen. Using a new approach to reconstitute antigen-receptor interactions in a human reporter B cell line, we found that sequence-defined BCRs from the human germline repertoire could be triggered by both complementarity to influenza HA and a separate mode of signaling that relied on multivalent ligation of BCR sialyl-oligosaccharide...

Importance: Outcomes for patients with pancreatic ductal adenocarcinoma (PDAC) remain poor. Advances in next-generation sequencing provide a route to therapeutic approaches, and integrating DNA and RNA analysis with clinicopathologic data may be a crucial step toward personalized treatment strategies for this disease. Objective: To classify PDAC according to distinct mutational processes, and explore their clinical significance. Design, Setting, and Participants: We performed a retrospective cohort study of resected PDAC, using cases collected between 2008 and 2015 as part of the International Cancer Genome Consortium...

OBJECTIVE: Test the feasibility of assessing cognition, psychiatric symptoms and daily living skills of potential brain donors by telephone and compare satisfaction and attitudes across telephone and face-to-face assessment. METHOD: Data were collected from 108 healthy participants from the Brains for Dementia Research cohort.

BACKGROUND: It is uncertain whether lymph node dissection (LND) provides a therapeutic benefit in renal cell carcinoma (RCC). OBJECTIVE: To evaluate the association of LND with oncologic outcomes among patients undergoing radical nephrectomy (RN) for nonmetastatic RCC. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study of 1797 patients treated with RN for M0 RCC between 1990 and 2010, including 606 (34%) who underwent LND. INTERVENTION: RN with or without LND...
