BACKGROUND: The effective management of pain in chronic pancreatitis (CP) remains a therapeutic challenge. Analgesic drugs, such as opioids, and the underlying pathology can impair gut function. The autonomic nervous system influences hormone secretion and gut motility. In healthy volunteers, electrical (using noninvasive transcutaneous vagal nerve stimulation [t-VNS]) and physiological (using deep slow breathing [DSB]) modulation of parasympathetic tone results in pain attenuation and enhanced gut motility...

BACKGROUND Mucinous ovarian adenocarcinoma is one of the less common epithelial cancers of the ovaries, and typically does not occur in younger women. Nearly all mucinous ovarian adenocarcinomas present with early-stage disease without significant sequelae of cancer, such as clotting. Anchoring bias is a common problem in medicine that has been shown to significantly affect physician decision-making. CASE REPORT We present the case of a 24-year-old healthy female Chinese immigrant with no significant past medical history, who presented with a subacute history of nonproductive cough and shortness of breath with exertion...

Acetylcholinesterase, with a deep, narrow active-site gorge, attracts enormous interest due to its particularly high catalytic efficiency and its inhibitors used for treatment of Alzheimer's disease. To facilitate the massive pass-through of the substrate and inhibitors, "breathing" motions to modulate the size of the gorge are an important prerequisite. However, the molecular mechanism that governs such motions is not well explored. Here, to systematically investigate intrinsic motions of the enzyme, we performed microsecond molecular dynamics simulations on the monomer and dimer of Torpedo californica acetylcholinesterase (TcAChE) as well as the complex of TcAChE bound with the drug E2020...

BACKGROUND: Surgical site infections (SSIs) are a common source of postoperative morbidity and a marker of surgical quality. The ability to predict the incidence of SSIs is limited and most models have poor predictive value. We sought to identify risk factors associated with SSIs and develop a prediction model for SSIs after major abdominal surgery. METHODS: A total of 1744 patients undergoing pancreatic, hepatobiliary, and colorectal resections between January 1, 2010 and August 31, 2013 at Johns Hopkins Hospital were identified...

The world's oceans are home to many fantastic creatures, including about 16,000 species of actinopterygian, or ray-finned, fishes. Notably, 85% of marine fish species come from a single actinopterygian subgroup, the acanthomorph or spiny-rayed fishes. Here, we review eight functional innovations found in marine acanthomorphs that have been instrumental in the adaptive radiation of this group in the marine realm. Jaw protrusion substantially enhances the suction feeding mechanism found in all fish. Fin spines serve as a major deterrent to predators and enhance the locomotor function of fins...

BACKGROUND: Affective learning is valued in nursing, but it is often difficult to plan and evaluate learning activities in this domain. Contemplative activities can promote learning and are relatively easy to implement. These activities can promote deep, reflective thinking. METHOD: A variety of contemplative activities were used in undergraduate nursing courses. Students participated in and reflected on a vigil promoting domestic violence awareness. They attended two different art exhibits and related these exhibits to nursing...

Cardiac autonomic neuropathy (CAN) is a common and most neglected complication of diabetes, estimated to be roughly 8% in recently diagnosed patients and greater than 50% in patients with chronic disease history. The insulin resistance (IR) itself is bidirectionally associated with increased risk of type 2 diabetes mellitus (T2DM) and CAN is a predisposing factor. The primary objective of the present study was aimed to find a correlation of triglyceride glucose index (TyG index) in CAN patients along with the prevalence of CAN in T2DM patients as a secondary objective...

OBJECTIVES: Respiratory rate (RR) is one of the most important vital signs used to detect whether a patient is in critical condition. It is part of many risk scores and its measurement is essential for triage of patients in emergency departments. It is often not recorded as measurement is cumbersome and time-consuming. We intended to evaluate the accuracy of camera-based measurements as an alternative measurement to the current practice of manual counting. MATERIALS AND METHODS: We monitored the RR of healthy male volunteers with a camera-based prototype application and simultaneously by manual counting and by capnography, which was considered the gold standard...

The automatic metabolic units calculate breath-by-breath gas exchange from the expiratory data only, applying an algorithm ('expiration-only' algorithm) that neglects the changes in the lung gas stores. These last are theoretically taken into account by a recently proposed algorithm, based on an alternative view of the respiratory cycle ('alternative respiratory cycle' algorithm). The performance of the two algorithms was investigated where changes in the lung gas stores were induced by abrupt increases in ventilation above the physiological demand...

OBJECTIVE: Evaluating the lung function in patients with obstructive lung disease by electrical impedance tomography (EIT) usually requires breathing maneuvers containing deep inspirations and forced expirations. Since these maneuvers strongly depend on the patient's co-operation and health status, normal tidal breathing was investigated in an attempt to develop continuous maneuver-free measurements. APPROACH: Ventilation related and pulsatile impedance changes were systematically analyzed during normal tidal breathing in 12 cystic fibrosis (CF) patients and 12 lung-healthy controls (HL)...
