Directional cell migration is of fundamental importance to a variety of biological events, including metastasis of malignant cells. Herein, we specifically investigated SET oncoprotein, a subunit of the recently identified inhibitor of acetyltransferases (INHAT) complex and identified its role in the establishment of front-rear cell polarity and directional migration in Esophageal Squamous Cell Carcinoma (ESCC). We further define the molecular circuits that govern these processes by showing that SET modulated DOCK7/RAC1 and cofilin signaling events...

BACKGROUND: In response to the lack of coverage for substance use treatment in the Western Cape province of South Africa, the local government expanded funding for evidence-based practices (EBPs) for treating substance use. Yet, little is known about provider and staff attitudes towards adopting EBPs in this setting, which is particularly relevant in this context where task shifting clinical care increases demands on paraprofessional providers. This study aimed to (1) assess attitudes towards adopting EBPs among a range of staff working in substance use treatment in Cape Town using a task shifting model; and (2) evaluate factors associated with openness towards adopting EBPs in this setting...

Acute appendicitis (AA) develops in a progressive and irreversible manner, even if the clinical course of AA can be temporarily modified by intentional medications. Reliable and real-time diagnosis of AA can be made based on findings of the white blood cell count and enhanced computed tomography. Emergent laparoscopic appendectomy (LA) is considered as the first therapeutic choice for AA. Interval/delayed appendectomy at 6-12 wk after disease onset is considered as unsafe with a high recurrent rate during the waiting time...

Co-circulation of zoonotic highly pathogenic avian influenza virus (HPAIV) H5N1 and AIV of subtype H9N2 among poultry in Egypt for at least six years should render this country a hypothetical hotspot for the emergence of reassortant, phenotypically altered viruses, yet no reassortants have been detected in Egypt. The present investigations proved that reassortants between Egyptian H5N1 clade 2.2.1.2 and H9N2 of the G1-B lineage can be generated by co-amplification in embryonated chicken eggs. Reassortants were restricted to the H5N1 subtype and had acquired between two and all six of the internal segments of the H9N2 virus...

REVIEW
Amanda Ward, Sara McComb
The purpose of this literature review is to examine studies evaluating preceptorships within nursing orientation or education programs. Nursing education in the classroom focuses on the theoretical aspect of nursing care as opposed to the clinical experience of nursing education that allows for the hands-on practical experience of nursing. The clinical experience is an integral part of the education process for both students and experienced nurses at various career transitions. Quality clinical experiences require practice partnerships, particularly in the form of preceptorships...

BACKGROUND: Clinicians in low resource settings in malaria endemic regions face many challenges in diagnosing and treating febrile illnesses in children. Given the change in WHO guidelines in 2010 that recommend malaria testing prior to treatment, clinicians are now required to expand the differential when malaria testing is negative. Prior studies have indicated that resource availability, need for additional training in differentiating non-malarial illnesses, and lack of understanding within the community of when to seek care play a role in effective diagnosis and treatment...

As medical educators continue to redefine learning and assessment across the continuum, implementation of competency-based medical education in the undergraduate setting has become a focus of many medical schools. While standards of competency have been defined for the graduating student, there is no uniform approach for defining competency expectations for students during their core clerkship year. The authors describe the process by which an Alliance for Academic Internal Medicine task force developed a paradigm for competency-based assessment of students during their inpatient internal medicine (IM) clerkship...

The transformation of the U.S. health care system is under way, driven by the needs of an aging population, rising health care spending, and the availability of health information. However, the speed and effectiveness of the transformation of health care delivery will depend, in large part, upon engagement of the health professions community and changes in clinicians' practice behaviors. Current efforts to influence practice behaviors emphasize changes in the health payment system with incentives to move from fee-for-service to alternative payment models...

REVIEW

The recent amendments notified by the Government of India, for conducting clinical trial, is greatly appreciable as promoting safety and well-being of human subjects. These rules clearly state that medical management of injuries in clinical trials is mandatory, and clinical trial-related injury or death needs to be compensated over and above the medical management. These rules need to be reconsidered for simplification and better understanding of issues regarding compensation. There is a need of clarity at some points which should be discussed with all stakeholders for better understanding of current regulations...

Porous biomaterials can be additively manufactured with micro-architecture tailored to satisfy the stringent mechano-biological requirements imposed by bone replacement implants. In a previous investigation, we introduced structurally porous biomaterials, featuring strength five times stronger than commercially available porous materials, and confirmed their bone ingrowth capability in an in-vivo canine model. While encouraging, the manufactured biomaterials showed geometric mismatches between their internal porous architecture and that of its as-designed counterpart, as well as discrepancies between predicted and tested mechanical properties, issues not fully elucidated...

BACKGROUND: Levels of overall physical activity have been shown to decline across childhood. Schools are considered ideal settings to promote physical activity as children spend a large amount of their waking hours at school. Time-efficient physical activity strategies that demonstrate a positive impact on academic-related outcomes are needed to enable physical activity to be prioritised in the school day. The ACTI-BREAK programme requires classroom teachers to integrate active breaks; 5-min bursts of moderate-intensity physical activity into their classroom routine...

BACKGROUND: Presently, preterm birth is globally the leading cause of neonatal mortality. Prompt community based identification of women at high risk for preterm births (HRPB) can either help to avert preterm births or avail effective interventions to reduce neonatal mortality due to preterm births. We evaluated the performance of a package to train community workers to detect the presence of signs or symptoms of HRPB. METHODS: Pregnant women enrolled in the intervention arm of a cluster randomized trial of Antenatal Corticosteroids (ACT Trial) conducted at Nagpur, India were informed about 4 directly observable signs and symptoms of preterm labor...

BACKGROUND: HIV persists as a public health emergency in South Africa, especially among women of childbearing age. In response to the HIV epidemic, the Joint United Nations Programme on HIV/AIDS has put forth the 90-90-90 global goals to achieve an AIDS-free generation by 2020. This goal aspires to have 90% of people living with HIV diagnosed; 90% of those who test positive on sustained antiretroviral therapy (ART); and 90% of those on ART be virally suppressed. Ensuring access to ART is an important first step in reducing HIV incidence, especially among vulnerable populations such as women who use substances and bear the burden of HIV in South Africa...

Lassa fever afflicts tens of thousands of people in West Africa annually. The rapid progression of patients from febrile illness to fulminant syndrome and death provides incentive for development of clinical prognostic markers that can guide case management. The small molecule profile of serum from febrile patients triaged to the Viral Hemorrhagic Fever Ward at Kenema Government Hospital in Sierra Leone was assessed using untargeted Ultra High Performance Liquid Chromatography Mass Spectrometry. Physiological dysregulation resulting from Lassa virus (LASV) infection occurs at the small molecule level...

The liver is organized in hexagonal functional units - termed lobules - characterized by a rather peculiar blood microcirculation, due to the presence of a tangled network of capillaries - termed sinusoids. A better understanding of the hemodynamics that governs liver microcirculation is relevant to clinical and biological studies aimed at improving our management of liver diseases and transplantation. Herein, we built a CFD model of a 3D sinusoidal network, based on in vivo images of a physiological mouse liver obtained with a 2-photon microscope...

P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) are clinically important efflux transporters that act cooperatively at the blood-brain barrier, limiting the entry of several drugs into the CNS and affecting their pharmacokinetics, therapeutic efficacy and safety. In the present study, the interactions of catechol-O-methyltransferase (COMT) inhibitors (BIA 9-1059, BIA 9-1079, entacapone, nebicapone, opicapone and tolcapone) with P-gp and BCRP were investigated in order to determine the contribution of these transporters in their access to the brain...
