BACKGROUND: It is assumed that recreational use of methamphetamine can trigger acute myocardial infarction (AMI) events, but estimates of longitudinal hazards of AMI among methamphetamine users are lacking. METHODS: Retrospective cohort study: Competing-risks analysis was used to estimate time-to-AMI patterns in methamphetamine versus matched appendicitis (population-proxy) and matched cocaine (drug-control) groups. Cohorts were propensity-score-matched using demographic and clinical variables...

The much over-looked element in new sanitation, the transport systems which bridge the source and treatment facilities, is the focus of this study. The knowledge of rheological properties of concentrated domestic slurry is essential for the design of the waste collection and transport systems. To investigate these properties, samples were collected from a pilot sanitation system in the Netherlands. Two types of slurries were examined: black water (consisting of human faecal waste, urine, and flushed water from vacuum toilets) and black water with ground kitchen waste...

Patellofemoral pain (PFP) is one of the most prevalent conditions within sports medicine, orthopaedic and general practice settings. Long-term treatment outcomes are poor, with estimates that more than 50% of people with the condition will report symptoms beyond 5 years following diagnosis. Additionally, emerging evidence indicates that PFP may be on a continuum with patellofemoral osteoarthritis. Consensus of world leading clinicians and academics highlights the potential benefit of delivering tailored interventions, specific to an individual's needs, to improve patient outcome...

The EU Commission Ecolabel and the Product and Environmental Footprint (PEF) aim at promoting the development and consumption of greener products. The product aquatic toxicity score from these 2 methods may lead in some circumstances to opposite conclusions. Although this could be interpreted as an inconsistency, the score should not be compared to each other but used in a complementary way. In short, CDV provided a "full" product formula aquatic toxicity score, even if some chemicals may never reach or persist in freshwater ecosystems...

This study has reported that a GR-5 DNAzyme based lead ion strip biosensor could exhibit an enhanced specificity with the assistance of graphene oxide (GO). This enhancement results from the specific π-stacking interaction between the ribose rings of the nucleobases and the carbon hexagons in GO which can reduce the false positive interference by removing unhybridized ssDNA during the annealing of GR-5 DNAzyme. Meanwhile, conjugate pad was sprayed with two kinds of AuNP-DNA probes, and nitrocellulose membrane test zone and control zone were immobilized with two kinds of biotin-DNA probes, respectively...

The key component of a microstructural diffusion MRI 'super-scanner' is a dedicated high-strength gradient system that enables stronger diffusion weightings per unit time compared to conventional gradient designs. This can, in turn, drastically shorten the time needed for diffusion encoding, increase the signal-to-noise ratio, and facilitate measurements at shorter diffusion times. This review, written from the perspective of the National Facility for In Vivo MR Imaging of Human Tissue Microstructure, an initiative to establish a shared 300 mT/m-gradient facility amongst the microstructural imaging community, describes ten advantages of ultra-strong gradients for microstructural imaging...

PURPOSE: Despite recent advances, allogeneic hematopoietic stem cell transplantation (alloHSCT) continues to be accompanied by a high rate of morbidity and mortality. Several scores have been developed to predict outcome after HSCT. The PAM score has been recently revised, and utilizes information on patient age, donor type, disease risk, cytomegalovirus (CMV) serostatus of patients and donors, and the forced expiratory volume in one second (FEV1). The aim of this study was to analyze the predictive power of the PAM score in an independent, large cohort of acute myeloid leukemia (AML) patients...

OBJECTIVE: The caesarean section rate is gradually increasing in most countries. The frequency of occurrence of foetal injury per birth is estimated to 1%. The majority of these injuries presents a low functional impact, but remains responsible for a significant neonatal morbidity. Even though the foetal risk factors are well documented in cases of vaginal birth, they have not been accurately identified for cesarean section. The aim of this study is to identify the risk factors for neonatal fracture during caesarean section...

Mycotoxins are secondary fungi metabolites that induce acute and chronic toxic effects in humans and animals. Simultaneous contamination of cereal-based products by multiple mycotoxins has been increasingly reported, including in food products usually consumed by children. Although some previous authors assessed the health risk of children exposed to multiple mycotoxins, scarce data are available on the risk associated with the ingestion of multiple mycotoxins through different food products. MYCOMIX, a national funded project, intended to contribute to fill this gap...

BACKGROUND: Women with a gynecologic cancer tend to be older, obese, and postmenopausal, characteristics that are associated with an increased risk for obstructive sleep apnea. However, there is limited investigation regarding the condition's prevalence in this population or its impact on postoperative outcomes. In other surgical populations, patients with obstructive sleep apnea have been observed to be at increased risk for adverse postoperative events. OBJECTIVES: To estimate the prevalence of obstructive sleep apnea among gynecologic oncology patients undergoing elective surgery and to investigate for a relationship between obstructive sleep apnea and postoperative outcomes...

Self-diffusion of water-soluble fullerene derivative (WSFD) C60 [S(CH2 )3 SO3 Na]5 H in mouse red blood cells (RBC) was characterized by 1 H pulsed field gradient NMR technique. It was found that a fraction of fullerene molecules (~13% of the fullerene derivative added in aqueous RBC suspension) shows a self-diffusion coefficient of (5.5 ± 0.8)·10-12  m2 /s, which is matching the coefficient of the lateral diffusion of lipids in the erythrocyte membrane (DL  = (5.4 ± 0.8)·10-12  m2 /s). This experimental finding evidences the absorption of the fullerene derivative by RBC...

The antiviral and immunomodulatory role of vitamin D has been shown in various viral infections. However, there is scanty literature available about the effect of vitamin D supplementation in herpes simplex virus-1 (HSV-1) infection. Therefore, the present study aimed to evaluate the role of two different forms of vitamin D: 25-hydroxyvitamin D3 (25D3) and 1,25-dihydroxyvitamin D3 (1,25D3) against HSV-1 in HeLa cells. The HeLa cells were supplemented with either 25D3 or 1,25D3 before HSV-1 infection and were studied after 6, 12, and 24 h postinfection (p...
