A substantial and variable placebo response can cause unreliable findings in clinical trials designed to demonstrate the efficacy of antidepressants, and the high rate of failed trials represents a major obstacle in the development of new drugs for major depressive disorder (MDD). However, the influence of demographic and symptom factors on the antidepressant effect remains to be established. The purpose of this study was to estimate the magnitude of this influence. A patient-level meta-analysis of data from double-blind, randomized, placebo-controlled trials involving the use of antidepressants for adults with MDD was performed...

Currently, there are sophisticated applications that make it possible to visualize medical images and even to manipulate them. These software applications are of great interest, both from a teaching and a radiological perspective. In addition, some of these applications are known as Free Open Source Software because they are free and the source code is freely available, and therefore it can be easily obtained even on personal computers. Two examples of free open source software are Osirix Lite® and 3D Slicer®...

Bacterial adhesion to stainless steel 316L (SS316L), which is an alloy typically used in many medical devices and food processing equipment, can cause serious infections along with substantial healthcare costs. This work demonstrates that nanotextured SS316L surfaces produced by electrochemical etching effectively inhibit bacterial adhesion of both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, but exhibit cytocompatibility and no toxicity toward mammalian cells in vitro. Additionally, the electrochemical surface modification on SS316L results in formation of superior passive layer at the surface, improving corrosion resistance...

The literature suggests that women of different races are more or less likely to use certain contraceptive methods and patient race can influence which contraceptive recommendations a provider makes. To explore whether health care providers treat individuals of different races differently, we conducted a preliminary investigation on whether medical students recommended different contraceptive methods for hypothetical patients presenting with the same clinical features who only varied by race. Third- and fourth-year medical students (n=103) at the University of Hawai'i completed an online survey...

Meropenem is a widely used antimicrobial for the treatment of infections associated with the use of invasive medical devices in intensive care unit patients. These treatments are not always effective, in fact, in-vitro studies have demonstrated the difficulty of antimicrobials to penetrate into the biofilm, however in-vivo studies of the effect of these compounds is a trend, mostly because of the complexity of pulmonary samples extracted from ETTs. Therefore, the objective of this study was to evaluate in-tube solid phase microextraction (in-tube SPME) coupled to capillary liquid chromatography (CapLC) with DAD to determine meropenem in ETTs in order to estimate the penetration capability into the biofilm...

DNA damage kills dry-heated spores of Bacillus subtilis, but dry heat-treatment effects on spore germination and outgrowth have not been studied. This is important, since if dry heat-killed spores germinate and undergo outgrowth, toxic proteins could be synthesized. Here, Raman spectroscopy and differential interference contrast microscopy were used to study germination and outgrowth of individual dry heat-treated B. subtilis and Bacillus megaterium spores. Major findings in this work were as follows. 1) Spores dry heat-treated at 140°C for 20 min nearly all lost viability but retained their Ca2+-dipicolinic acid (CaDPA) depot...

Biofilm formation on abiotic surfaces in food and medical industry can cause severe contamination and infection, yet how biological and physical factors determine cellular architecture of early biofilms and bacterial behavior of the constituent cells remains largely unknown. In this study we examine the specific role of type-I fimbriae in nascent stages of biofilm formation and the response of micro-colonies to environmental flow shear at single-cell resolution. The results show that type-I fimbriae are not required for reversible adhesion from plankton, but critical for irreversible adhesion of Escherichia coli (E...

BACKGROUND: Nowadays, digital self-tracking devices offer a plethora of possibilities to both healthy and chronically ill users who want to closely examine their body. This study suggests that self-tracking in a private setting will lead to shifting understandings in professional care. To provide more insight into these shifts, this paper seeks to lay bare the promises and challenges of self-tracking while staying close to the everyday professional experience of the physician. OBJECTIVE: The aim of this study was to (1) offer an analysis of how medical doctors evaluate self-tracking methods in their practice and (2) explore the anticipated shifts that digital self-care will bring about in relation to our findings and those of other studies...

BACKGROUND: Outbreaks of health care-associated infections (HAIs) caused by Burkholderia cepacia complex (Bcc) have been associated with medical devices and water-based products. Water is the most common raw ingredient in nonsterile liquid drugs, and the significance of organisms recovered from microbiologic testing during manufacturing is assessed using a risk-based approach. This incident demonstrates that lapses in manufacturing practices and quality control of nonsterile liquid drugs can have serious unintended consequences...

The functionalization of alumina nanoparticles of specific morphology with antimicrobial peptides (AMP) can be a promising strategy for modeling medical devices and packaging materials for cosmetics, medicines or food, since the contamination by pathogens could be reduced. In this paper, we show the synthesis of a fibrous-like alumina nanobiostructure, as well as its functionalization with the peptide EAAA-BP100, an analog of the antimicrobial peptide BP100. The antibacterial activity of the obtained material against some bacterial strains is also investigated...

INTRODUCTION: A basal-bolus insulin regimen is needed to achieve glycated hemoglobin A1c (HbA1c) below 7.0% in people with type 1 (T1D) or type 2 (T2D) diabetes who have significant loss of beta-cell function. Nonadherence to therapy is common and negatively affects the ability to reach treatment goals. We examined patient assessment of a new, wearable mealtime insulin-delivery system (patch) relative to their current mealtime insulin-delivery system (syringe, pen, or pump). The patch is designed to deliver only boluses of fast-acting insulin (no basal insulin), mechanically controlled by the patient...

Rare diseases pose particular challenges to patients who are affected, to the clinicians who care for them, and to the investigators who study their conditions. Though individually uncommon, rare diseases are common in the aggregate, with the ∼7000 described rare diseases affecting 25-30 million Americans. Challenges posed to affected individuals and their families largely regard being diagnosed; receiving optimal care; and affording disease-specific medications. Challenges facing clinicians who care for affected individuals include gaining knowledge and experience in caring for such patients, and the availability of local experts and of expert guidelines...

BACKGROUND: Few studies have demonstrated detailed physical risk factors of hemorrhagic complications (HC) associated with the Angio-Seal closure device. This retrospective study aimed to identify the risk factors of HC due to Angio-Seal use. METHODS: Data from 143 cases that underwent neurointerventional procedures that involved puncturing the femoral artery and that used an Angio-Seal to close the puncture site were reviewed. We divided these cases into HC and no HC groups and retrospectively compared age, sex, past medical and preference history, body mass index (BMI), femoral artery depth, dual antiplatelet therapy use, activated clotting time, general anesthesia use, sheath size, right femoral artery puncture, and treatment time...

There is considerable interest in transcatheter prosthetic valve treatment for mitral valve disease in high-risk individuals. Although the presence of mitral annular calcium (MAC) may provide an anchoring zone for such devices, results to date have been modest with reported technical failure rates approaching 30% in specialist centers. This in part relates to the risk of left ventricular outflow tract obstruction and device dislodgment but also to the lack of specific imaging guidelines to plan for such procedures...

BACKGROUND: The interleukin-33 (IL-33)/supressor of tumorigenicity 2 (ST2) pathway is suggested to play an important role in fibrosis, remodeling and the progression of heart failure (HF). Increased soluble (sST2) levels are associated with adverse outcome in the average HF population. Less is known about sST2 levels in end-stage HF. Therefore, we studied sST2 levels in end-stage HF and the effect of unloading by left ventricular assist device (LVAD) support on sST2 levels. METHOD AND RESULTS: Serial plasma measurements of sST2 were performed pre-implantation and 1, 3 and 6 months after (LVAD) implantation in 38 patients...
