Despite a great deal of opposition from many segments of the medical community, the Medical Council of India (MCI) has proposed to the Ministry of Health and Family Welfare, Government of India that a pan-India exit examination be introduced for graduating MBBS doctors. Whether the proposal should be put forward was considered twice, once in 2010 and again in 2013, and finally the plan was ready to be taken forward seriously in 2015. The proposal has elicited appreciation and criticism from different segments of the medical community...

BACKGROUND: Flies have some of the most elaborate visual systems in the Insecta, often featuring large, sexually dimorphic eyes with specialized "bright zones" that may have a functional role during mate-seeking behavior. The fast visual system of flies is considered to be an adaptation in support of their advanced flight abilities. Here, we show that the immense processing speed of the flies' photoreceptors plays a crucial role in mate recognition. RESULTS: Video-recording wing movements of abdomen-mounted common green bottle flies, Lucilia sericata, under direct light at 15,000 frames per second revealed that wing movements produce a single, reflected light flash per wing beat...

To determine whether the laryngeal mask airway (LMA) has advantages over the tracheal tube (TT) in terms of incidence of cough, sore throat, laryngospasm, dysphagia, dysphonia, and blood staining. This is a systematic literature review performed at the Universtity Medical Center of Utrecht. The online databases PubMed, Embase, and the Cochrane Library were searched for relevant randomized controlled trials. Two independent reviewers selected relevant articles after title, abstract, and full text screening. Articles were assessed on risk of bias in accordance with the Cochrane risk of bias tool...

BACKGROUND: It is hypothesized that Affordable Care Act (ACA) Medicaid expansions could substantially improve access to health insurance and healthcare services for patients at risk for diabetes mellitus (DM), with pre-DM, or already diagnosed with DM. The ACA called for every state to expand Medicaid coverage by 2014. In a 2012 legal challenge, the US Supreme Court ruled that states were not required to implement Medicaid expansions. This 'natural experiment' presents a unique opportunity to learn whether and to what extent Medicaid expansion can affect healthcare access and services for patients with DM risk, pre-DM, or DM...

Pigment patterns throughout the animal kingdom repeatedly utilise shared motifs (solid spots, hollow spots, stripes in different orientations), begging the question of whether these are generated by the same or different mechanisms in each case. Although intuitively this might seem unlikely, a whole body of work on mathematical modelling of these patterns suggests that, in theory at least, all such patterns could share an underlying mechanism. Within the mammals, one such motif is alternating longitudinal dark and light stripes, whether the supremely contrasting facial stripes of European Meles meles and American Badgers Taxidea taxus or the more subtle and more numerous stripes of the head, flanks and back of chipmunks, Tamias...

In a recent battle between reproductive rights and religious freedom, the U.S. Supreme Court, by a five to three vote, declined to review an appeal in Stormans, Inc v Wiesman, a case brought by a Washington state pharmacy owner and two pharmacists who held religious objections to emergency contraception. These petitioners brought a constitutional challenge to Washington state regulations that required pharmacies to dispense all lawfully prescribed pharmaceuticals. In 2015, the Ninth Circuit Court of Appeals ruled that these regulations did not violate the Constitution...

Despite the extensive discovery of disease-associated common variants, much of the genetic contribution to complex traits remains unexplained. Rare variants may explain additional disease risk or trait variability. Although sequencing technology provides a supreme opportunity to investigate the roles of rare variants in complex diseases, detection of these variants in sequencing-based association studies presents substantial challenges. In this article, we propose novel statistical tests to test the association between rare and common variants in a genomic region and a complex trait of interest based on cross-validation prediction error (PE)...

When the Supreme Court heard argument in City & County of San Francisco v. Sheehan in the spring of 2015, it intended to resolve a circuit split. In granting certiorari, the Court planned to clarify whether individuals with disabilities can sue police officers under the ADA if an officer fails to accommodate a disability in the course of an arrest. However, because the petitioners failed to brief the Court on that question, the portion of the case involving the ADA was dismissed as improvidently granted. Justices Scalia and Kagan were so enraged by the failure to brief on the "certworthy" question that they issued a partial dissent, refusing to issue opinions on any of the attendant issues...

INTRODUCTION: The laryngeal mask airway (LMA)-Supreme is a disposable double-lumen laryngeal mask airway that is widely used in clinical practice. However, its use in obese children has not been evaluated. The aim of this study was to determine whether the LMA-Supreme could perform equally as well as endotracheal intubation in obese children having a minor surgical procedure. MATERIAL AND METHODS: After ethical board approval, 100 obese male children receiving non-emergent appendectomy for chronic appendicitis or surgery to correct concealed penis were randomly divided into an endotracheal intubation group and an LMA-Supreme group...

There are not any laws in Italy that rule the path of the end of life. Therefore, the doctor has to take as a reference the Supreme Judgment of the Court of Cassation 16/10/2007 n 21748. The author is proposing a different, realistic and convenient form that could be used by the patient and both his tutor and doctor to walk through the path that brings to the end of life. This document shows respect for the sanctity of life and safeguards willingness and dignity of the patient. Its purpose is to register the treatment for symptoms that leads to death, basing the relationship between a patient and his doctor on trust and confidence...

The objective of this in vitro study was to evaluate whether irradiation of enamel with a novel CO2 9.3-μm short-pulsed laser using energies that enhance caries resistance influences the shear bond strength of composite resin sealants to the irradiated enamel. Seventy bovine and 240 human enamel samples were irradiated with a 9.3-μm carbon dioxide laser (Solea, Convergent Dental, Inc., Natick, MA) with four different laser energies known to enhance caries resistance or ablate enamel (pulse duration from 3 μs at 1...

This article reviews 100 years of research on recruitment and selection published in the Journal of Applied Psychology. Recruitment and selection research has been present in the Journal from the very first issue, where Hall (1917) suggested that the challenge of recruitment and selection was the Supreme Problem facing the field of applied psychology. As this article shows, the various topics related to recruitment and selection have ebbed and flowed over the years in response to business, legal, and societal changes, but this Supreme Problem has captivated the attention of scientist-practitioners for a century...

The news has been peppered with tragic stories of individuals with disabilities who have been killed or injured following police encounters. In the aftermath of these incidents, as injured parties seek accountability, a question looms: Can arrest proceedings violate the Americans with Disabilities Act? The ADA was enacted to prohibit disability discrimination. The law had an ambitious agenda, supported by broad statutory authority, to ensure equality in all areas of public life for individuals with disabilities...

BACKGROUND: Fiberoptical assisted intubation via placed supraglottic airway devices has been described as safe and easy procedure to manage difficult airways. However visualization of the glottis aperture is essential for fiberoptical assisted intubation. Various different supraglottic airway devices are commercially available and might offer different conditions for fiberoptical assisted intubation. The aim of this study was to compare the best obtainable view of the glottic aperture using different supraglottic airway devices...

OBJECTIVES: Lifesavers in Australia are taught to use pocket mask (PM) rescue breathing and bag valve mask (BVM) ventilation, despite evidence that first responders might struggle with these devices. Novices have successfully used the Laryngeal Mask Airway (LMA) Supreme and iGel devices previously, but there has been no previous comparison of the ability to train lifesavers to use the supraglottic airways compared to standard techniques for cardiac arrest ventilation. METHODS: The study is a prospective educational intervention whereby 113 lifesavers were trained to use the LMA and iGel supraglottic airways...

Delivery room infections are frequent, and many of them could be avoided through higher standards of care. The authors examine this issue by comparing it to English and French reality. Unlike England, in Italy and France the relationship established between health facility, physician and patient is outlined in a contract. In England, the judges' decisions converge toward a better and higher protection of the patient-the actor-and facilitate the probative task. In case of infections, including those occurring in the delivery room, three issues are evaluated: the hospital's negligent conduct, damages if any and causal nexus...
