Banked blood exhibits impairments in nitric oxide (NO)-based oxygen delivery capability, reflected in rapid depletion of S-nitrosohemoglobin (SNO-Hb). We hypothesized that transfusion of even freshly-stored blood used in pediatric heart surgery would reduce SNO-Hb levels and worsen outcome. In a retrospective review (n = 29), the percent of estimated blood volume (% eBV) replaced by transfusion directly correlated with ventilator time and inversely correlated with kidney function; similar results were obtained in a prospective arm (n = 20)...

BACKGROUND: In order to achieve elimination of trachoma, a country needs to demonstrate that the elimination prevalence thresholds have been achieved and then sustained for at least a two-year period. Ghana achieved the thresholds in 2008, and since 2011 has been implementing its trachoma surveillance strategy, which includes community and school screening for signs of follicular trachoma and trichiasis, in trachoma-endemic districts. In 2015-2016, the country conducted a district level population-based survey to validate elimination of trachoma as a public health problem...

Gloves are worn by workers harvesting ready-to-eat produce as a deterrent for contaminating the produce with enteric pathogens that may reside on their hands. As fields are not sterile environments, the probability for gloves to become contaminated still exists and therefore it is critical to understand the conditions that affect the survival of pathogens on gloves. Both Escherichia coli O157:H7 and Salmonella deposited on glove surfaces in a liquid state survived longer when the pathogen had been suspended in lettuce sap than when suspended in water...

J Seelig
Knowledge of protein stability is of utmost importance in various fields of biotechnology. Protein stability can be assessed in solution by increasing the concentration of denaturant and recording the structural changes with spectroscopic or thermodynamic methods. The standard interpretation of the experimental data is to assume a 2-state equilibrium between completely folded and completely unfolded protein molecules. Here we propose a cooperative model based on the statistical-mechanical Zimm-Bragg theory...

Betweenness has been used in a number of marine studies to identify portions of sea that sustain the connectivity of whole marine networks. Herein we highlight the need of methodological exactness in the calculation of betweenness when graph theory is applied to marine connectivity studies based on transfer probabilities. We show the inconsistency in calculating betweeness directly from transfer probabilities and propose a new metric for the node-to-node distance that solves it. Our argumentation is illustrated by both simple theoretical examples and the analysis of a literature data set...

INTRODUCTION: Since 1996 we have been using cementless fixation with hydroxyapatite (HA) coating. The purpose of this paper is to compare survivorship of a series of 100 cemented Total Knee Arthroplasty (TKA) to a similar series of 100 cementless with a follow up of 11-16 years. Material methods: Both TKA are mobile bearing total knee postero-stabilized. They can be used with cement or without cement. Among 1030 New Wave TKATM implanted from 2002 to 2015 we have identified 100 cemented TKAs and 100 cementless TKAs...

Arsenic occurs in marine waters, typically at concentrations of 1-2 μg As kg-1, primarily as the inorganic species arsenate. Marine animals, however, contain extremely high levels of arsenic (typically 2,000-20,000 μg As kg-1 wet mass), most of which is present as arsenobetaine, an organic form of arsenic that has never been found in seawater. We report a method based on ion-exchange pre-concentration and HPLC/mass spectrometry to measure arsenobetaine in seawater, and apply the method to samples of seawater collected at various depths from seven sites in the North Atlantic...

BACKGROUND: Because of the recent grade C draft recommendation by the US Preventive Services Task Force (USPSTF) for prostate cancer screening between the ages of 55 and 69 years, there is a need to determine whether this could be cost-effective in a US population setting. METHODS: This study used a microsimulation model of screening and active surveillance (AS), based on data from the European Randomized Study of Screening for Prostate Cancer and the Surveillance, Epidemiology, and End Results Program, for the natural history of prostate cancer and Johns Hopkins AS cohort data to inform the probabilities of referral to treatment during AS...

While analysing the use of the new videolaryngoscopes in the hands of the well experienced anaesthesiologists it is difficult to get answers to all intriguing questions and gain insights that might arise only from the untrained users. We can form a thesis that if a manikin, with the use of a particular device, is intubated quickly and effectively by the novices, it is probable that the more experienced operators will be even more satisfied with its use. AIM: The aim of our study was to evaluate the effectiveness of the use of these devices in the hands of the users untrained in intubation...

Background: Paracetamol overdose/abuse as a result of self-medication is a common occurrence amongst people living in low/middle income countries. The present study was designed to investigate the hypolipidemic and cardioprotective potentials of Vernonia calvoana (VC) ethanol extract in acetaminophen (paracetamol)-treated rats. Methods: Thirty-five Wistar rats weighing 100-150 g were randomly assigned into five groups of seven rats each. Groups 2-5 received high doses of paracetamol to induce liver damage, while group 1 was used as normal control...

For the medical practice, our manuscript acts as a signal, despite only presenting three cases which feature the association between hepatocytolysis, haemolysis and hypermagnesaemia. This clinical-biologic triad was highlighted with the workers who through the nature of their profession were exposing themselves periodically to vapours which contained copper sulphate neutralised with calcium hydroxide, a fungicide used for fruit trees. We are exclusively assessing the haematological perturbation. In this aetiological context, the generating mechanism for haemolysis is very probable biochemical, where hypercupraemia interferes with cellular antioxidant defence mechanisms...

Vitamin D is essential for the maintenance and promotion of musculoskeletal health, for the functioning of the immune, cardiovascular and reproductive systems, and its main action is to keep calcium and phosphate plasmatic physiological concentrations at intestinal, renal and bony level. Vitamin D affects several parameters related to physical performance too and a particularly high percentage of vitamin D insufficiency and deficiency in professional athletes has been observed. Several variables are able to impair the synthesis of 25(OH)D in athletes, specifically both genetic and environmental factors, but the most probable explanation for the deficient/insufficient vitamin D levels is the insufficient ultraviolet B light (UVB) exposure during winter...

The clinical manifestation and clinical diagnosis and treatment of acupuncture for persistent somatoform pain disorder (PSPD) were observed to explore its etiology. It is found that the causative factor of PSPD is probably relevant with pain memory induced by the negative emotions during the first attack of pain, which is in the category of "depression" in TCM. In clinical diagnosis, the medical history should be explored to discover the potential etiology and determine the diagnosis. In treatment, the root cause should be considered, focusing on mind and qi regulation and associating with analgesia...

Fifty-nine acupoints for febrile disease is recorded in Huangdi Neijing (Huangdi's Internal Classics). By analyzing the combination of these acupoints, the writer discovered the acupoint composition and detected their origins from Huangdi's Internal Classics, in which the terms biaoben, qijie and beishu are involved in the theoretic evidence. The writer thought the "fifty-nine acupoints for febrile disease" implied the self-evolution of some acupuncture school in ancient time, which was formed by absorbing the theoretic experiences of the other schools...

BACKGROUND: Renal dysfunction increases the risk of thromboembolic and bleeding events in patients with nonvalvular atrial fibrillation (NVAF). MATERIALS AND METHODS: Adult NVAF patients with ≥ 6 months prior to first warfarin or rivaroxaban dispensing were selected from the IMS Health Real-World Data Adjudicated Claims database (05/2011 - 06/2015) with electronic medical records. Ischemic stroke events, thromboembolic events (venous thromboembolism, myocardial infarction, or ischemic stroke), and major bleeding events were compared between patients by renal function identified by 1) relevant ICD-9-CM diagnosis codes and 2) estimated creatinine clearance (eCrCl)...

Little is known about the epidemiology of human brucellosis in sub-Saharan Africa. This hampers prevention and control efforts at the individual and population levels. To evaluate risk factors for brucellosis in northern Tanzania, we conducted a study of patients presenting with fever to two hospitals in Moshi, Tanzania. Serum taken at enrollment and at 4-6 week follow-up was tested by Brucella microagglutination test. Among participants with a clinically compatible illness, confirmed brucellosis cases were defined as having a ≥ 4-fold rise in agglutination titer between paired sera or a blood culture positive for Brucella spp...
