#1
REVIEW
Shira Kramer, Colin L Soskolne
PURPOSE OF REVIEW: This review integrates historical developments and key events in bringing ethics into epidemiology in general and into environmental epidemiology in particular. The goal is to provide context for and discern among the various approaches and motivations that drive the need for ethical conduct in support of the public interest. RECENT FINDINGS: The need for ethics guidelines in epidemiology is different from developments in other biomedical-related fields by virtue of its focus on populations rather than on individuals...

The human brain requires a wide variety of experiences and environmental inputs in order to develop normally. Children who are neglected by caregivers or raised in institutional environments are deprived of numerous types of species-expectant environmental experiences. In this review, we articulate a model of how the absence of cognitive stimulation and sensory, motor, linguistic, and social experiences common among children raised in deprived early environments constrains early forms of learning, producing long-term deficits in complex cognitive function and associative learning...

REVIEW
Brian G Weinshenker, Dean M Wingerchuk
The understanding of neuromyelitis optica spectrum disorder (NMOSD) has evolved substantially since its initial description over a century ago. The discovery in 2004 of a pathogenic autoantibody biomarker targeting aquaporin 4 IgG revolutionized diagnosis and therapeutic development. Although NMOSD resembles multiple sclerosis (MS), differences were identified and articulated in the late 1990s. New diagnostic criteria incorporating the biomarker as well as better understanding of the clinical and radiologic features of NMOSD now permit accurate diagnosis and differentiation from MS...

BACKGROUND: Literature indicates that one of the most important factors affecting the widespread adoption of Health Information Exchange (HIE) is patient support and endorsement. In order to reap all the expected benefits of HIE, patients' acceptance of technology is a challenge that is not fully studied. There are a few studies which have focused on requirements of electronic medical information exchange from consumers' views and expectations. This study is aimed at reviewing the literature to articulate factors that affect patients to support HIE efforts...

BACKGROUND: Approximately one-third of reduced pediatric distal radius fractures redisplace, resulting in further treatment. Two major modifiable risk factors for loss of reduction are reduction adequacy and cast quality. Closed reduction and immobilization of distal radius fractures is an Accreditation Council for Graduate Medical Education residency milestone. Teaching and assessing competency could be improved with a life-like simulation training tool. QUESTIONS/PURPOSES: Our goal was to develop and validate a realistic distal radius fracture reduction and casting simulator as determined by (1) a questionnaire regarding the "realism" of the model and (2) the quantitative assessments of reduction time, residual angulation, and displacement...

Background Research productivity is a major indicator of higher educational institutions' (HEI) academic performance. The increasing focus on research productivity is resulting in an expectation that academics publish their research initiatives, ideas and developments in their scope of work or area of interest. It can influence academic status and compel nursing academics to undertake higher degrees, including PhDs or other doctoral studies. Aim To articulate a nurse academic's reflection on presenting her doctoral thesis at an international conference and to encourage students to embrace the dissemination of research...

BACKGROUND AND PURPOSE: Implementation of contextually appropriate, evidence-based, expert-recommended stroke prevention guideline is particularly important in Low-Income Countries (LMICs), which bear disproportional larger burden of stroke while possessing fewer resources. However, key quality characteristics of guidelines issued in LMICs compared with those in High-Income Countries (HICs) have not been systematically studied. We aimed to compare important features of stroke prevention guidelines issued in these groups...

GroupA streptococci (GAS) cause a wide spectrum of diseases ranging from benign pharyngitis and skin infections to severe invasive disease and the immune sequelae rheumatic fever and rheumatic heart disease. Pharyngitis, one of the most frequent diseases caused by GAS, is highly prevalent in school-age children in temperate climates and a major cause of antibiotic use. An efficacious vaccine would reduce disease burden associated with pharyngitis and the need of care for sick children. Importantly, GAS pharyngitis is recognised as the main precursor for acute rheumatic fever so a vaccine that is efficacious against GAS pharyngitis should also prevent acute rheumatic fever and rheumatic heart disease...

Todd O Yeates
Emerging protein design strategies are enabling the creation of diverse, self-assembling supramolecular structures with precision on the atomic scale. The design possibilities include various types of architectures: finite cages or shells, essentially unbounded two-dimensional and three-dimensional arrays (i.e., crystals), and linear or tubular filaments. In nature, structures of those types are generally symmetric, and, accordingly, symmetry provides a powerful guide for developing new design approaches. Recent design studies have produced numerous protein assemblies in close agreement with geometric specifications...

Nitin Kumar
Endoscopic gastric plication techniques are effective for weight loss. These procedures offer the potential for higher efficacy than conservative modalities, such as medications and lifestyle modifications, and lower invasiveness than bariatric surgery. Gastric plication techniques include endoscopic sleeve gastroplasty, primary obesity surgery endolumenal, transoral gastroplasty, and plication with the Articulating Endoscopic Circular (ACE) stapler. Currently, primary obesity surgery endolumenal is under review by the US Food and Drug Administration, and endoscopic sleeve gastroplasty is gaining acceptance...

Advanced respiratory diseases progress over time and often lead to death. As their condition worsens, patients may lose medical decision making ability. Advance care planning (ACP) is a process in which patients receive information about their diagnosis and prognosis; discuss values, goals and fears; articulate preferences about life-sustaining treatments and end-of-life care; and appoint a surrogate medical decision maker. This process may result in written documentation of patient preferences, or appointment of a health care power of attorney (HCPOA)...

The menisci are intricately organized structures that perform many tasks in the knee. We review their structure and function and introduce new data about their tibial and femoral surfaces. As the femur and tibia approach each other when the knee is bearing load, circumferential tension develops in the menisci, enabling the transmission of compressive load between the femoral and tibial cartilage layers. A low shear modulus is necessary for the tissue to adapt its shape to the changing radius of the femur as that bone moves relative to the tibia during joint articulation...

Questions are raised in effective utilization of farmer's wisdom by communities in their farming. Planners support to livelihood emphasize mostly of inputs from outside and not setting up sustainable goals. Formal institutions and planners of program are finding constraints and sceptical in wider dissemination of indigenous knowledge research system (IKRS). This is in spite of evidence that considerable number of farmer's in livestock sector depends on IKRS. In this context, it is pertinent to showcase dissemination potential of these knowledge system(s) in larger geographical areas...

OBJECTIVES: Patients who articulate their psychological distress primarily through physical symptoms (referred to as medically unexplained symptoms (MUS)) pose a challenge to the skills of most clinicians, including palliative care physicians. The philosophical underpinnings of palliative care with a stated focus on symptom management and care of the person in their psychosociospiritual context lend itself to the care of these patients. The aim of this study was to investigate the characteristics to improve identification of this patient group within palliative care...

We survey models of response inhibition having different degrees of mathematical, computational and neurobiological specificity and generality. The independent race model accounts for performance of the stop-signal or countermanding task in terms of a race between GO and STOP processes with stochastic finishing times. This model affords insights into neurophysiological mechanisms that are reviewed by other authors in this volume. The formal link between the abstract GO and STOP processes and instantiating neural processes is articulated through interactive race models consisting of stochastic accumulator GO and STOP units...

BACKGROUND: The pyriform aperture comprises the central area of facial bone structure. It is formed by the free corners of the nasal bone and the frontal processes of the maxillae, which articulate with each other at the nasomaxillary suture lines. Congenital nasal pyriform aperture stenosis might be linked to various craniofacial problems. This review presents all aspects of pyriform aperture stenosis and enlargement. METHODS: A literature search was conducted...

Nasal reconstruction has been articulated in the literature since 700 B.C. when the earliest iteration of the forehead flap was described in the Indian medical treatise, the Sushruta Samhita. Since then it has evolved into the interpolated flap which has served as a powerful tool for facial reconstruction. The interpolated flap is constructed from nonadjacent donor tissue that has an inherent blood supply. It requires a multistaged approach and is best suited for reconstruction of large or deep defects of the nose...

Osteoarthritis (OA) affects millions of people and results in weakened hyaline cartilage due to overloading. During joint articulation, hyaline cartilage must withstand high loads while maintaining low friction to prevent wear and tissue loss. Thus, cartilage compressive stiffness and the coefficient of friction are important indicators of the tissue's functional performance. These mechanical properties are often measured ex vivo using mechanical testing regimens, but arthroscopic handheld probes (e.g., for indentation testing, ultrasound, and optical coherence tomography) and noninvasive imaging modalities (e...
