BACKGROUND: Numerous studies have reported a strong association between temperature and mortality. Additional insights can be gained from investigating the effects of temperature on years of life lost (YLL), considering the life expectancy at the time of death. OBJECTIVES: The goal of this work was to assess the association between temperature and YLL at seven low-, middle-, and high-income sites. METHODS: We obtained meteorological and population data for at least nine years from four Health and Demographic Surveillance Sites in Kenya (western Kenya, Nairobi), Burkina Faso (Nouna), and India (Vadu), as well as data from cities in the United States (Philadelphia, Phoenix) and Sweden (Stockholm)...

OBJECTIVE: Endovascular aneurysm repair (EVAR) can be performed through percutaneous or surgical access. Our goal was to assess the difference in perioperative outcomes based on access type in a real-world setting. METHODS: The Vascular Quality Initiative (VQI) database was queried for EVAR. Univariable analysis and multivariable analysis were used to determine the independent effect of access type. RESULTS: There were 8340 (64%) and 4747 (36%) EVAR procedures performed through percutaneous and surgical access (3395 [72%] transverse and 1352 [28%] vertical incisions)...

A neuronal population is a computational unit that receives a multivariate, time-varying input signal and creates a related multivariate output. These neural signals are modeled as stochastic processes that transmit information in real time, subject to stochastic noise. In a stationary environment, where the input signals can be characterized by constant statistical properties, the systematic relationship between its input and output processes determines the computation carried out by a population. When these statistical characteristics unexpectedly change, the population needs to adapt to its new environment if it is to maintain stable operation...

Inferring mathematical models of sensory processing systems directly from input-output observations, while making the fewest assumptions about the model equations and the types of measurements available, is still a major issue in computational neuroscience. This letter introduces two new approaches for identifying sensory circuit models consisting of linear and nonlinear filters in series with spiking neuron models, based only on the sampled analog input to the filter and the recorded spike train output of the spiking neuron...

Two novel synthetic protocols for the syntheses of highly functionalized five-membered carbocyclic enaminonitriles and β-enaminoesters have been developed via domino ring-opening cyclization (DROC) and DROC/decarboxylative tautomerization of activated cyclopropanes with malononitrile pronucleophiles, respectively. Both of the efficient strategies (yield up to 93%) have been generalized with various donor-acceptor and acceptor cyclopropanes as well as with malononitrile derivatives. The stereospecific variants of the two SN2-type DROC strategies have also been developed by employing enantiopure donor-acceptor (DA) cyclopropanes to synthesize the corresponding nonracemic products with excellent stereoselectivities (dr up to >99:1, ee up to >99%)...

Immune checkpoint inhibitor (ICPI) therapy unleashes the body's natural immune system to fight cancer. ICPIs improve overall cancer survival, however the unbridling of the immune system may induce a variety of immune related adverse events. Neuromuscular immune complications are rare but they can be severe. Myasthenia gravis and inflammatory neuropathy are the most common neuromuscular adverse events but a variety of others including inflammatory myopathy are reported. The pathophysiologic mechanism of these autoimmune disorders may differ from that of non-ICPI related immune diseases...

INTRODUCTION: Patients with myasthenia gravis often experience fatigue, but its effect on quality of life (QoL) is underestimated, and fatigue is rarely measured in clinical trials. METHODS: 257 myasthenic patients completed the Neuro-QoL-Fatigue and measures of disease severity and QoL. We studied the relationship between fatigue, clinical, and demographic variables. Finally, we studied the responsiveness of the Neuro-QoL-Fatigue in 95 patients receiving treatments for myasthenia, and estimated the minimal important difference (MID)...

Background: Muscle-invasive bladder cancers (MIBCs) cause approximately 150 000 deaths per year worldwide. Survival for MIBC patients is heterogeneous, with no clinically validated molecular markers that predict clinical outcome. Non-MIBCs (NMIBCs) generally have favorable outcome; however, a portion progress to MIBC. Hence, development of a prognostic tool that can guide decision-making is crucial for improving clinical management of bladder urothelial carcinomas. Methods: Tumor grade is defined by pathologic evaluation of tumor cell differentiation, and it often associates with clinical outcome...

The analysis of channel power and electric field strength at various locations from mobile base stations using power sensor, spectrum analyzer and log-periodic antenna revealed maximum potential exposure between the range of 61.1 and 254.7 m. Generally, the potential exposure values ranged from 0.0717 to 0.8950 mW m-2 with a maximum deviation of 22.22%. GSM900 was found to be more pronounced than GSM1800 and UMTS2100. Though the results complied with ICNIRP reference levels with a wide margin of 0.01%, it was higher than some previous work and South African mean value of 0...

Background: While evidence is increasingly consistent with a positive association between periodontitis and cancer risk, most studies have relied on self-reported periodontitis. In this study, we prospectively evaluated the association of periodontal disease severity with cancer risk in black and white older adults in a cohort study that included a dental examination. Methods: Included were 7466 participants in the Atherosclerosis Risk in Communities study cohort who at visit 4 (1996-1998) reported being edentulous or underwent the dental examination...

Advances in DNA sequencing technology open new possibilities for public health genomics, especially in the form of general population preventive genomic sequencing (PGS). Such screening programs would sit at the intersection of public health and preventive health care, and thereby at once invite and resist the use of clinical ethics and public health ethics frameworks. Despite their differences, these ethics frameworks traditionally share a central concern for individual rights. We examine two putative individual rights-the right not to know, and the child's right to an open future-frequently invoked in discussions of predictive genetic testing, in order to explore their potential contribution to evaluating this new practice...

Background: Differences in the epidemiology of post-transplant lymphoproliferative disease (PTLD) between adult and paediatric kidney transplant recipients remain unclear. Methods: Using the Australian and New Zealand Dialysis and Transplant Registry (1963-2015), the cumulative incidences of PTLD in children (age <20 years) and adults were calculated using a competing risk of death model and compared with age-matched population-based data using standardized incidence ratios (SIRs)...

Background: Some of the most widely recognised coral-reef fishes are clownfish or anemonefishes, members of the family Pomacentridae (subfamily: Amphiprioninae). They are popular aquarium species due to their bright colours, adaptability to captivity and fascinating behavior. Their breeding biology (sequential hermaphrodites) and symbiotic mutualism with sea anemones have attracted much scientific interest. Moreover, there are some curious geographic-based phenotypes which warrant investigation...

Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. The thulium laser decreases the risk of bleeding and perforation in endoscopy but has not been reported in digestive diseases, especially in POEM...

Background: A modest rise in blood pressure (BP) reportedly increases cardiovascular mortality despite not reaching obvious hypertension, suggesting that target organ damages are latently induced by slight BP rising. The goal of this study was to determine whether presence of subclinical myocardial damage can predict the future development of hypertension in the normotensive general population. Methods and results: The cohort study was conducted with subjects who participated in a community-based annual health check...

Objectives: Noise exposure is a common occupational hazard, but has not been sufficiently characterized in paper mills. We developed a job-exposure matrix (JEM) for noise exposure for use in estimating exposures among Swedish soft tissue paper mill workers. Methods: We used a combination of area and personal dosimetry noise exposure measurements made at four soft tissue paper mills by industry and research staff between 1977 and 2013 to estimate noise exposures by department, location, and job title...

Suspended particles in rivers can act as carriers of potentially bioavailable metal species and are thus an emerging area of interest in river system monitoring. The delineation of bulk metals concentrations in river water into dissolved and particulate components is also important for risk assessment. Linear relationships between bulk metal concentrations in water (CW,tot) and total suspended solids (TSS) in water can be used to easily evaluate dissolved (CW, intercept) and particle-bound metal fluxes (CSUS, slope) in streams (CW,tot = CW + CSUS TSS)...

BACKGROUND: Red cell distribution width (RDW) predicts disease outcome in several patient populations, but its prognostic value in addition to other disease parameters in unselected medical inpatients remains unclear. Our aim was to investigate the association of admission RDW levels and mortality adjusted for several disease pathways in unselected medical patients from a previous multicenter study. METHODS: We included consecutive adult, medical patients at the time point of hospital admission through the emergency department into this observational, cohort study...

Conventional education results in unsatisfactory morphological understanding of acetabular fractures due to lack of three-dimensional (3D) details and tactile feedback of real fractures. Virtual reality (VR) and 3D printing (3DP) techniques are widely applied in teaching. The purpose of this study was to identify the effect of physical model (PM), VR and 3DP models in education of morphological understanding of acetabular fractures. 141 students were invited to participate in this study. Participants were equally and randomly assigned to the PM, VR and 3DP learning groups...
