BACKGROUND: Interventions to interrupt transmission of malaria from humans to mosquitoes represent an appealing approach to assist malaria elimination. A limitation has been the lack of systems to test the efficacy of such interventions before proceeding to efficacy trials in the field. We have previously demonstrated the feasibility of induced blood stage malaria (IBSM) infection with Plasmodium vivax. In this study, we report further validation of the IBSM model, and its evaluation for assessment of transmission of P...

Interpretation of postmortem morphine concentrations in forensic toxicology provides several pitfalls such as missing information on tolerance, analyte stability, or postmortem redistribution (PMR). Recently, it had been shown that computed tomography (CT)-guided collection of biopsies using a robotic arm (virtobot) provides a valuable strategy for systematic studies on time-dependent PMR. Using this technique, time-dependent PMR of morphine and its metabolites was investigated in 12 cases. At admission to the institute (t1), femoral and heart blood (right ventricle) as well as biopsies from the right lung, the right kidney, liver, spleen, and muscle tissue were collected...

BACKGROUND: Increasing vascular endothelial growth factor (VEGF) has been reported in remitting symmetrical seronegative synovitis with pitting edema (RS3PE) syndrome, rheumatoid arthritis (RA), polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). The aim of this study was to compare VEGF levels in patients over 60 years of age who have RS3PE, RA, PMR or GCA so as to determine whether elevated VEGF is specific for a rheumatic disease, the inflammation or edema that occurs with these pathological conditions...

BACKGROUND: Many cancer patients use a wide variety of techniques to improve their physical and mental well-being, including relaxation therapy and, specifically, Progressive Muscle Relaxation (PMR). However, there is no strong evidence that supports the efficacy of this technique. OBJECTIVE: Our aim was to review the evidence regarding the use of PMR as a supportive intervention for cancer patients undergoing chemotherapeutic treatment. METHOD: Six databases were electronically searched: AMED, the Cochrane Library, MEDLINE, PsychINFO, Scopus, and the Web of Science...

BACKGROUND: Post-infarction cardiac rupture (CR) such as ventricular septal rupture (VSR), free wall rupture (FWR), atrial septal rupture (ASR) or papillary muscle rupture (PMR) is a rare but dreaded complication in patients with acute myocardial infarction (AMI) associated with a very poor prognosis with reported mortality rates between 60 and 100%. Therefore suitable risk stratification for secondary prevention seems crucial, but data on long-term survival und risk prediction in this especially vulnerable patient collective remains scarce...

In the last few years, the relationship between polymyalgia rheumatica (PMR) and cancer has been considered with very different conclusions. In particular, in 2010, Ji et al examined the overall and specific cancer risks among Swedish subjects following hospitalization for PMR and giant cell arteritis and noted that the risk of cancer was highest in the first year after hospitalization (of 3941 total cancer diagnoses, 783 [19.1%] were in the first year). In 2013, Muller et al, using data from General Practice Research Database, highlighted that elderly patients with a PMR diagnosis were significantly more likely to receive a cancer diagnosis in the year after PMR diagnosis (313/667 cancer cases [69%])...

OBJECTIVES: The diagnostic diversity of polymyalgia rheumatica (PMR) can easily be obscured by the widespread use of corticosteroids (CSs) early in the disease course. This study observed the course of PMR without CSs and determined whether alternative medication could be useful. METHODS: Seventy patients with new-onset PMR comprised phase 1. Eight were removed with specific diagnoses (four with giant cell arteritis [GCA]). The remaining 62 were treated with nonsteroidal anti-inflammatory drugs (NSAIDs) alone until enough time had elapsed to ascertain whether their PMR had evolved into another rheumatologic inflammatory condition...

Gideon Nesher, Gabriel S Breuer
Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are both more common among people of North European decent than among Mediterranean people. Women are 2-3 times more commonly affected. Giant cell arteritis and PMR are extremely rare before age 50 years. Polymyalgia rheumatica may be "isolated" or associated with GCA. There is increased expression of inflammatory cytokines in temporal arteries of PMR patients, without overt histological evidence of arteritis. One-third of "isolated" PMR patients have vascular uptake in positron emission tomography (PET) scans, suggesting clinically unrecognized, "hidden" GCA...

Treatment for type 1 Gaucher disease (GD1) decreases morbidity from hematological cytopenias, hepatosplenomegaly and bone complications. Consequently, untreated symptomatic patients for study of late outcomes are hard to find. We identified 184 untreated GD1 patients (67.4% Ashkenazi; splenectomy 51.1%) who died between 1950 and 2010. Here, we report confirmed causes of death for these patients compared with the overall US population. Median age of death 66years (2-97years); causes of death (COD) with a high proportional mortality rate (PMR) included malignancies (PMR 1...

Postmortem redistribution (PMR) concerns blood drug concentration variations after death, depending on many factors such as sampling site and technique. In our study, we focused on sampling method. 30 cases were sampled, each at cardiac, subclavian, femoral, and popliteal sites. Targeted substances were diazepam, methadone, and morphine. Blind stick and dissection/clamping techniques were concomitantly performed at subclavian and femoral sites. Subclavian and femoral concentrations were compared according to technique used...

Background: The timing of infection is closely determined in controlled human malaria infection (CHMI) studies, and as such they provide a unique opportunity to dissect changes in immunological responses before and after a single infection. The first Kenyan Challenge Study (KCS) (Pan African Clinical Trial Registry: PACTR20121100033272) was performed in 2013 with the aim of establishing the CHMI model in Kenya. This study used aseptic, cryopreserved, attenuated Plasmodium falciparum sporozoites administered by needle and syringe (PfSPZ Challenge) and was the first to evaluate parasite dynamics post-CHMI in individuals with varying degrees of prior exposure to malaria...

Tumor recurrence is an important problem threatening esophageal cancer patients after surgery, even when they achieve a pathologic major response (pMR) after neoadjuvant concurrent chemoradiation therapy (CCRT). The predictors related to overall survival and disease progression for these patients remain elusive. We aimed to identify factors that predict disease progression and overall survival in esophageal squamous cell carcinoma (SCC) patients who achieve a pMR after neoadjuvant CCRT followed by surgery. We conducted a retrospective study to analyze the factors influencing survival and disease progression after esophagectomy for esophageal cancer patients who had a major response to CCRT, which is defined by complete pathological response or microscopic residual disease without lymph node metastasis...

Research involving working memory has indicated that stress and anxiety compete for attentional resources when a person engages in attention-dependent cognitive processing. The purpose of this study was to investigate the impact of perceived stress and state anxiety on working memory and academic performance among health science students and to explore whether the reduction of stress and anxiety was achieved through progressive muscle relaxation (PMR) training. A convenience sample of 128 graduate students participated in this study...

INTRODUCTION: Steroid-resistant nephrotic syndrome (SRNS) inevitably progresses to end-stage kidney disease, requiring dialysis or transplantation for survival. However, treatment modalities and drug discovery remain limited. Mutations in over 30 genes have been discovered as monogenic causes of SRNS. Most of these genes are predominantly expressed in the glomerular epithelial cell, the podocyte, placing it at the center of the pathogenesis of SRNS. Podocyte migration rate (PMR) represents a relevant intermediate phenotype of disease in monogenic causes of SRNS...

Grazing intensity elicits changes in the composition of plant functional groups in both shortgrass steppe (SGS) and northern mixed-grass prairie (NMP) in North America. How these grazing intensity-induced changes control aboveground net primary production (ANPP) responses to precipitation remains a central open question, especially in light of predicted climate changes. Here, we evaluated effects of four levels (none, light, moderate, and heavy) of long-term (>30 yr) grazing intensity in SGS and NMP on: (1) ANPP; (2) precipitation-use efficiency (PUE, ANPP : precipitation); and (3) precipitation marginal response (PMR; slope of a linear regression model between ANPP and precipitation)...

OBJECTIVE: The skin color/race and urbanity are structural determinants of health. The relationship between these variables produces structure of social stratification that defines inequalities in the experiences of life and death. Thus, this study describes the characteristics of the mortality indicators by skin color/race according level of urbanity and aggregation to the metropolitan region (MR) of 5565 cities in Brazil, controlling for gender and age. DESIGN: Descriptive study which included the calculation of measures relating to 1,050,546 deaths in the year survey of 2010 by skin color/race White, Black, and Brown according to both sexes, for five age groups and three levels of urbanity of cities in Brazil that were aggregated or not to the MR in the year of study...

OBJECTIVE: In the case of high erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, the diagnosis of the underlying disease can be challenging especially in serologically unrevealing patients who have nonspecific clinical findings. We aimed to investigate the final distribution of definitive diagnoses in patients who initially presented with nonspecific clinical findings and sustained elevations in serum ESR/CRP levels. MATERIAL AND METHODS: The medical records of patients hospitalized in a rheumatology clinic between January 2010 and January 2011 were retrospectively analyzed...
