Monitoring intracranial pressure in comatose patients with severe traumatic brain injury (TBI) is considered necessary by most experts. Acute intracranial hypertension (IHT), when severe and sustained, is a life-threatening complication that demands emergency treatment. Yet, secondary anoxic-ischemic injury after brain trauma can occur in the absence of IHT. In such cases, adding other monitoring modalities can alert clinicians when the patient is in a state of energy failure. This article reviews the mechanisms, diagnosis, and treatment of IHT and brain hypoxia after TBI, emphasizing the need to develop a physiologically integrative approach to the management of these complex situations...

The impacts of ZVI on microbial community diversity in an anaerobic assay with high organic loading were investigated. The relative abundance of bacteria, archaea, and the functional methyl coenzyme-M reductase (mcrA) gene were investigated using high-throughput sequencing, and variations in their quantity were determined by qPCR. The results showed that ZVI significantly increased both the relative abundance and quantity of Methanobacteriales and Methanosarcinales during hydrogenotrophic and acetoclastic methanogenesis...

BACKGROUND: Hospitalization is a common method to intensify care for patients experiencing a psychiatric crisis. A short-term, specialised, out-patient crisis intervention by a Crisis Resolution Team (CRT) in the Netherlands, called Intensive Home Treatment (IHT), is a viable intervention which may help reduce hospital admission days. However, research on the (cost-)effectiveness of alternatives to hospitalisation such as IHT are scarce. In the study presented in this protocol, IHT will be compared to care-as-usual (CAU) in a randomized controlled trial (RCT)...

BACKGROUND: Recently, increased tumor incidence and cancer-related mortality have been reported among patients with obstructive sleep apnea (OSA). Intermittent hypoxia (IH), the hallmark feature of OSA, contributes to the metastasis of tumors. However, the molecular mechanisms by which tumor metastasis is accelerated by OSA-like IH remain to be elucidated. METHODS: C57BL/6 J male mice were subjected to intravenous injection of B16F10 melanoma cells before receiving IH treatment...

BACKGROUND: Transfer of critically ill patients within the hospital is commonly associated with adverse incidents, but, despite this, no standardised training exists on how to carry out this task. Very little information is published in the literature on the learning needs of staff undertaking these transfers, and this limits our ability to provide a focused and appropriate educational intervention. AIMS: This study aimed to explore the organisational, environmental and individual issues that increase risk to patients during intrahospital transport (IHT) and to explore the potential educational solutions to these issues as articulated by these practitioners...

OBJECTIVE: Interhospital transfers (IHTs) to tertiary care centers are linked to lower operative mortality in vascular surgery patients. However, IHT incurs great health care costs, and some transfers may be unnecessary or futile. In this study, we characterize the patterns of IHT at a tertiary care center to examine appropriateness of transfer for vascular surgery care. METHODS: A retrospective review was performed of all IHT requests made to our institution from July 2014 to October 2015...

OBJECTIVE: A locally advanced Gleason 4 + 4 prostate cancer patient who was on self-medication with intermittent anti-androgen monotherapy (iAAm) over 14 years suggested that raised testosterone was not dangerous and this suggestion needed investigating. PATIENTS: Others who were on AA continuously were recruited to ongoing audit of intermittent hormone therapy (IHT) and iAAm outcomes were compared with intermittent LHRH therapy (iLHRH or iMAB). RESULTS: Between 1994 and 2007, 111 patients sought IHT because of side effects of treatment...

To identify the ideal harvest time (IHT) for the seed production of XY335 and ZD958, six seed-related traits were evaluated in seeds harvested at 11 harvest stages in 8 environments. Standard germination (SG), accelerated aging germination (AAG) and cold test germination (CTG) were vigor traits; hundred-seed weight (HSW) and seed moisture content (SMC) were physiological traits; and ≥10 °C accumulated temperature from pollination to harvest (AT10ph) was an ecological trait. All the traits were significantly affected by harvest stage...

BACKGROUND: The use of interactive health technology (IHT) is a promising pathway to tackle self-management problems experienced by many chronically ill patients, including solid organ transplant (Tx) patients. Yet, to ensure that the IHT is accepted and used, a human-centered design process is needed, actively involving end users in all steps of the development process. A first critical, predevelopment step involves understanding end users' characteristics. This study therefore aims to (a) select an IHT platform to deliver a self-management support intervention most closely related to Tx patients' current use of information and communication technologies (ICTs), (b) understand Tx patients' overall willingness to use IHT for self-management support, and investigate associations with relevant technology acceptance variables, and (c) explore Tx patients' views on potential IHT features...

Great effort has recently been devoted to the preparation of nanoscale surfaces on titanium-based implants to achieve clinically fast osteoinduction and osseointegration, which relies on the unique characteristics of the nanostructure. In this work, we used induction heating treatment (IHT) as a rapid oxidation method to fabricate a porous nanoscale oxide layer on the Ti6Al4V surface for better medical application. Well-distributed vertical nanopillars were yielded by IHT for 20-35 s on the alloy surface. The composition of the oxides contained rutile/anatase TiO2 and a small amount of Al2 O3 between the TiO2 grain boundaries (GBs)...

BACKGROUND: Intrahospital patient transports (IHTs) in intensive care involve an appreciable risk of adverse events (AEs). Research on determinants of AE occurrence during IHT has hitherto focused on patient, transport, and intensive care unit (ICU) characteristics. By contrast, the role of "soft" factors, although arguably relevant for IHTs and a topic of interest in general health care settings, has not yet been explored. PURPOSE: The study aims at examining the effect of safety climate and team processes on the occurrence of AE during IHT and whether team processes mediate the effect of safety climate...

BACKGROUND: Emergency general surgery (EGS) admissions account for more than three million hospitalizations in the US annually; and interhospital transfers (IHTs) are costly. We aimed to better understand the population of transferred EGS patients and their subsequent care in a nationally representative sample. METHODS: Using the 2002-2011 Nationwide Inpatient Sample, we identified patients aged ≥18 years with an EGS noncardiovascular principal diagnosis who were transferred from another hospital with urgent or emergent admission status...

A genome-wide association study (GWAS) correlates marker and trait variation in a study sample. Each subject is genotyped at a multitude of SNPs (single nucleotide polymorphisms) spanning the genome. Here, we assume that subjects are randomly collected unrelateds and that trait values are normally distributed or can be transformed to normality. Over the past decade, geneticists have been remarkably successful in applying GWAS analysis to hundreds of traits. The massive amount of data produced in these studies present unique computational challenges...

The main objective of this research was to evaluate the efficacy of intermittent hypoxic training (IHT) on anaerobic and aerobic capacity and swimming performance in well-trained swimmers. Sixteen male swimmers were randomly divided into a hypoxia (H) group (n = 8), which trained in a normobaric hypoxia environment, and a control (C) group (n = 8), which exercised under normoxic conditions. However, one participant left the study without explanation. During the experiment group H trained on land twice per week in simulated hypoxia (FiO2 = 15...

The present study aimed at examining beneficial effects of intermittent hypoxia training (IHT) under prediabetic conditions. We investigate the effects of three-week IHT on blood glucose level, tolerance to acute hypoxia, and leukocyte mRNA expression of hypoxia inducible factor 1α (HIF-1α) and its target genes, i.e. insulin receptor, facilitated glucose transporter-solute carrier family-2, and potassium voltage-gated channel subfamily J. Seven healthy and 11 prediabetic men and women (44-70 years of age) were examined before, next day and one month after three-week IHT (3 sessions per week, each session consisting 4 cycles of 5-min 12% O2 and 5-min room air breathing)...
