BACKGROUND: Alcohol use disorders (AUDs) are more prevalent among people who are homeless than in the general population. Thus, homeless individuals experience disproportionately high levels of alcohol-related problems and associated publicly funded criminal justice and healthcare system utilization. Available treatment services, however, are not effective at engaging and treating this population. To better tailor treatment services to their needs, it is imperative we understand this population's perceptions of their alcohol use...

BACKGROUND: Spinal cord stimulation (SCS) is an effective therapy to reduce pain in patients that suffer from failed back surgery syndrome (FBSS). In order to inform patients optimally prior to this therapy, knowing their expectations is crucial. METHODS: Thirteen patients suffering from FBSS and scheduled for SCS were interviewed, using a semi-structured protocol. Patients were interviewed either at home or at their treating hospital. Data from these interviews were analyzed using directed content analysis...

Traumatic brain injury (TBI) is a leading cause of death in young adults, and effective treatment strategies have the potential to save many lives. TBI results in coagulopathy, endothelial dysfunction, inflammation, cell death, and impaired epigenetic homeostasis, ultimately leading to morbidity and/or mortality. Commonly used resuscitation fluids such as crystalloids or colloids have several disadvantages and might even be harmful when administered in large quantities. There is a need for next-generation treatment strategies (especially in the prehospital setting) that minimize cellular damage, improve survival, and enhance neurological recovery...

Bilgesu A Bilgin, Ozgur B Akan
In this paper we analyse molecular communications (MC) in a proposed artificial synapse (AS), whose main difference from biological synapses (BSs) is that it is closed, i.e., transmitter molecules cannot diffuse out from AS. Such a setup has both advantages and disadvantages. Besides higher structural stability, being closed, AS never runs out of transmitters. Thus, MC in AS is disconnected from outer environment, which is very desirable for possible intra-body applications. On the other hand, clearance of transmitters from AS has to be achieved by transporter molecules on the presynaptic membrane of AS...

The number of genetic tests, mostly real-time PCRs, to detect antimicrobial resistance (AMR) determinants and predict AMR in Neisseria gonorrhoeae is increasing. Several of these assays are promising, but there are important shortcomings and few assays have been adequately validated and quality assured. Areas covered: Recent advances, focusing on publications since 2012, in the development and use of molecular tests to predict gonococcal AMR for surveillance and for clinical use, advantages and disadvantages of these tests and of molecular AMR prediction compared with phenotypic AMR testing, and future perspectives for effective use of molecular AMR tests for different purposes...

BACKGROUND: For decades, the main imaging tool in multiple myeloma (MM) patients was plain radiography. However, computed tomography (CT) has been included in the updated criteria of MM. The main disadvantage of CT is a considerably high radiation dose. Therefore, low-dose CT protocols could be a solution. The aim of the study was to (1) preliminarily analyse the usefulness of Whole-Body Low-Dose CT (WBLDCT) in the evaluation of patients with MM and (2) to make adjustments in the standard CT imaging protocol...

Formaldehyde (FA) is endogenously produced in live systems and has been implicated in a diverse array of pathophysiological processes. To disentangle the detailed molecular mechanisms of FA biology, a reliable method for monitoring FA changes in live cells would be indispensable. Although there have been several fluorescent probes reported to detect FA, most are limited by the slow detection kinetics and the intrinsic disadvantage of detecting FA in an irreversible manner which may disturb endogenous FA homeostasis...

Andreas Albertsen, Jens Damgaard Thaysen
The exposure of doctors, nurses and other medical professionals to risks in the context of epidemics is significant. While traditional medical ethics offers the thought that these dangers may limit the extent to which a duty to care is applicable in such situations, it has less to say about what we might owe to medical professionals who are disadvantaged in these contexts. Luck egalitarianism, a responsibility-sensitive theory of distributive justice, appears to fare particularly bad in that regard. If we want to maintain that medical professionals are responsible for their decisions to help, cure and care for the vulnerable, luck egalitarianism seems to imply that their claim of justice to medical attention in case of infection is weak or non-existent...

BACKGROUND: Stereotactic transcerebellar biopsies of brainstem tumors have often been reported. The Leksell frame or Cosman-Roberts-Wells frame is often used in transcerebellar approaches. However, to access lesions via the cerebellum, these frames should be secured as inferiorly on the cranium as possible, which can require exaggerated neck flexion and limit the flexible trajectory to the target. To overcome these disadvantages, we have devised a new way to use the Leksell frame for transcerebellar approaches...

BACKGROUND: Homicide - a lethal expression of violence - has garnered little attention from public health researchers and health policy makers, despite the fact that homicides are a cause of preventable and premature death. Identifying populations at risk and the upstream determinants of homicide are important for addressing inequalities that hinder population health. This population-based study investigates the public health significance of homicides in Ontario, Canada, over the period of 1999-2012...

Profile signals of urine samples corresponding to patients with lung cancer and controls were obtained using a non-separative methodology. The method is based on the coupling of a headspace sampler, a programed temperature vaporizer and a mass spectrometer (HS-PTV-MS). With only a centrifugation step as prior sample treatment, the samples were subjected to the headspace generation process and the volatiles generated were introduced into the PTV where they were trapped in the Tenax® packed liner while the solvent was purged...

Up until recently in France, physicians who obtained their degrees outside the European Union had a specifically disadvantaged status, that was supposed to be eliminated by the end of 2016. Until that date, a selective qualification process authorized foreign physicians to “full practice”. The deadline has been postponed to 2017 to resolve the complicated situations of certain doctors and to avoid tensions in hospital wards. These developments raise questions about the working conditions and motivations for migration of foreign medical doctors, particularly African doctors, who participate in the French healthcare system, and the obstacles to their integration...

Many industries are striving for the development of more reliable and robust β-galactosidase biosensors that exhibit high response rate, increased detection limit and enriched useful lifetime. In a newfangled technological atmosphere, a trivial advantage or disadvantage of the developed biosensor may escort to the survival and extinction of the industry. Several alternative strategies to immobilize β-galactosidase enzyme for their utilization in biosensors have been developed in recent years in the quest of maximum utility by controlling the defects seen in the previous biosensors...

Among various infections, chronic osteomyelitis is one of the most challenging in terms of treatment. This infection is more common among patients with open fractures and those who have undergone elective orthopedic procedures. The treatment of osteomyelitis requires high antibiotic doses and an aggressive and multifaceted surgical approach. The use of parenteral antibiotics alone, without debridement, is not sufficiently effective, due to the formation of sequestra and the low vascularity of the affected area...
