BACKGROUND: The inclusion criteria of all placebo-controlled studies of antidepressants have required a minimum level of severity on standardized measures of symptoms of depression. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we examined the association between scores on the Hamilton Depression Rating Scale (HAMD) and the number of criteria met for MDD, as well as the impact of different HAMD cutoff scores on the distribution of the number of DSM-IV criteria met...

OBJECTIVE: Spectral power analyses of EEG recordings are reported to distinguish the cortical activity of individuals with chronic pain from those of controls. Further study of these spectral patterns may provide a greater understanding of the processes associated with chronic pain, in addition to providing potential biometric markers of chronic pain for use in both clinical and research settings. However, sleep deprived groups have demonstrated similar characteristics in their spectral power characteristics, particularly in alpha bandwidth power activity...

PURPOSE OF THE STUDY: Converging evidence from large community-based samples, Internet studies, and Veterans Health Administration data suggest that transgender adults have high rates of U.S. military service. However, little is known about the role of prior military service in their mental health later in life, particularly in relation to identity stigma. In this article, we examine relationships between prior military service, identity stigma, and mental health among transgender older adults...

BACKGROUND AND OBJECTIVES: Ordering rates for imaging studies and procedures may change if clinicians are shown the prices of those tests while they are ordering. We studied the effect of 2 forms of paid price information, single median price and paired internal/external median prices, on how often pediatric-focused and adult-oriented clinicians (most frequently general pediatricians and adult specialists caring for pediatric-aged patients, respectively) order imaging studies and procedures for 0- to 21-year-olds...

Immunity can co-operate with antibiotics, but can also antagonize drug efficacy by segregating the bacteria to areas of the body that are less accessible to antimicrobials, and by selecting for subpopulations with low division rates that are often difficult to eradicate. We studied the effect of an anti-inflammatory/immunosuppressive anti-TNFα treatment, which accelerates bacterial growth in the tissues and inhibits or reverses the formation of granulomas, on the efficacy of ampicillin and ciprofloxacin during a systemic Salmonella enterica infection of the mouse...

On December 22, 2014, the U. S. Food and Drug Administration (FDA) granted accelerated approval to nivolumab (OPDIVO®, Bristol-Myers Squibb) for the treatment of patients with unresectable or metastatic melanoma and disease progression following ipilimumab and, if BRAF V600 mutation-positive, a BRAF inhibitor. Approval was based on a clinically meaningful, durable objective response rate (ORR) in a non-comparative analysis of 120 patients who received nivolumab 3 mg/kg intravenously every 2 weeks with at least 6 months follow-up in an ongoing, randomized, open-label, active-controlled clinical trial...

An intrinsic timing mechanism specifies the positional values of the zeugopod (i.e. radius/ulna) and then autopod (i.e. wrist/digits) segments during limb development. Here we have addressed if this timing mechanism ensures that patterning events occur only once by grafting GFP-expressing autopod progenitor cells to the earlier host signaling environment of zeugopod progenitor cells. We show that early and late autopod progenitors fated for the wrist and phalanges, respectively, both contribute to the entire host autopod indicating that the autopod positional value is irreversibly determined as revealed by Hoxa13 expression...

INTRODUCTION: Atrial fibrillation (AF) is a cause of stroke and a marker of atherosclerosis and of all patients with stroke, around 17% have AF. The screening and treatment of AF could prevent about 12% of all strokes. Several relatively low-cost devices with good accuracy now exist which can detect AF including WatchBP and AliveCor. However, they can only measure the ECG or pulse over short time periods. Inexpensive devices such as heart rate monitors, which are widely available, can measure heart rate for prolonged periods and may have potential in screening for AF...

: Acid mine drainage (AMD) is a major environmental problem affecting tens of thousands of km of waterways worldwide. Passive bioremediation of AMD relies on microbial communities to oxidize and remove iron from the system; however, iron-oxidation rates in AMD environments are highly variable across sites. At Scalp Level Run (Cambria County PA), first-order iron-oxidation rates are ten times faster than at other coal associated iron mounds in the Appalachians. We examined the bacterial community at Scalp Level Run to determine whether a unique community is responsible for the rapid iron oxidation rate...

The production of nitric oxide (NO) is a key defense mechanism against intracellular pathogens but it must be tightly controlled in order to avoid excessive detrimental oxidative stress. In this study we described a novel mechanism through which interleukin (IL)-6 mediates the regulation of NO release induced in response to Trypanosoma cruzi infection. Using a murine model of Chagas disease, we found that, in contrast to C57BL/6 wild type (WT) mice, IL-6-deficient (IL6KO) mice exhibited a dramatic increase in plasma NO levels concomitant with a significantly higher amount of circulating IL-1β and inflammatory monocytes...

Current conditioning regimens provide insufficient disease control in relapsed/refractory acute leukemia (AL) patients undergoing hematopoietic stem cell transplantation (HSCT) with active disease. Intensification of chemotherapy and/or total body irradiation (TBI) is not feasible because of excessive toxicity. Total marrow and lymphoid irradiation (TMLI) allows for precise delivery and increased intensity treatment via sculpting radiation to sites with high disease burden or high risk for disease involvement, while sparing normal tissue...

It is often challenging to precisely manipulate the release behavior of hydrophilic drugs that is believed to be crucial for a satisfactory therapeutic outcome. The aim of this work was to regulate the dissolution of hydrophilic drug from hot-melt extruded solid dispersion via rational screening of the pore-forming agents. Venlafaxine hydrochloride and Compritol® 888 ATO was selected as the model drug and carrier excipient, respectively. Hydrophilic polyethylene glycol (PEG 6000) and polyvinylpyrolidone (PVP K30) were chosen as the transient pore-forming agents...

Transmission-blocking vaccines (TBV) interrupt malaria parasite transmission and hence form an important component for malaria eradication. Mosquito midgut exopeptidases such as aminopeptidase N & carboxypeptidase B have demonstrated TBV potential. In the present study, we cloned and characterized carboxypeptidase A (CPA) from the midgut of an important malarial vector, Anopheles stephensi. ClustalW amino acid alignment and in silico 3-dimensional structure analysis of CPA predicted the presence of active sites involved in zinc and substrate binding that are conserved among all the known mosquito species...

BACKGROUND: In addition to reducing vaccine-type nasopharyngeal carriage rates, pneumococcal conjugate vaccines (PCVs) may decrease carriage density in vaccinated individuals still carrying vaccine serotypes. However, reduction of carriage density has not been systematically studied. This study compared the effect of PCV13 versus PCV7 on carriage density of the serotypes in PCV13 that are not included in PCV7. METHODS: This randomized, double-blind study was conducted in southern Israel and included Jewish and Bedouin subjects...
