The COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) project is a large international collaborative effort to analyze individual-level phenotype data from twins in multiple cohorts from different environments. The main objective is to study factors that modify genetic and environmental variation of height, body mass index (BMI, kg/m2) and size at birth, and additionally to address other research questions such as long-term consequences of birth size. The project started in 2013 and is open to all twin projects in the world having height and weight measures on twins with information on zygosity. Thus far, 54 twin projects from 24 countries have provided individual-level data. The CODATwins database includes 489,981 twin individuals (228,635 complete twin pairs). Since many twin cohorts have collected longitudinal data, there is a total of 1,049,785 height and weight observations. For many cohorts, we also have information on birth weight and length, own smoking behavior and own or parental education. We found that the heritability estimates of height and BMI systematically changed from infancy to old age. Remarkably, only minor differences in the heritability estimates were found across cultural–geographic regions, measurement time and birth cohort for height and BMI. In addition to genetic epidemiological studies, we looked at associations of height and BMI with education, birth weight and smoking status. Within-family analyses examined differences within same-sex and opposite-sex dizygotic twins in birth size and later development. The CODATwins project demonstrates the feasibility and value of international collaboration to address gene-by-exposure interactions that require large sample sizes and address the effects of different exposures across time, geographical regions and socioeconomic status.
We present a broad study of linear, clustered, noble gas puffs irradiated with the frequency doubled (527 nm) Titan laser at Lawrence Livermore National Laboratory. Pure Ar, Kr, and Xe clustered gas puffs, as well as two mixed-gas puffs consisting of KrAr and XeKrAr gases, make up the targets. Characterization experiments to determine gas-puff density show that varying the experimental parameter gas-delay timing (the delay between gas puff initialization and laser-gas-puff interaction) provides a simple control over the gas-puff density. X-ray emission (>1.4 keV) is studied as a function of gas composition, density, and delay timing. Xe gas puffs produce the strongest peak radiation in the several keV spectral region. The emitted radiation was found to be anisotropic, with smaller X-ray flux observed in the direction perpendicular to both laser beam propagation and polarization directions. The degree of anisotropy is independent of gas target type but increases with photon energy. X-ray spectroscopic measurements estimate plasma parameters and highlight their difference with previous studies. Electron beams with energy in excess of 72 keV are present in the noble gas-puff plasmas and results indicate that Ar plays a key role in their production. A drastic increase in harder X-ray emissions (X-ray flash effect) and multi-MeV electron-beam generation from Xe gas-puff plasma occurred when the laser beam was focused on the front edge of the linear gas puff.
Introduction: Point-of-care ultrasonography (PoCUS) is being incorporated into Canadian undergraduate medical school curricula. The purpose of this study was to evaluate novel PoCUS education sessions to determine what aspects of the sessions benefitted from hands-on training and which PoCUS skills were retained over time. Methods: Second year medical students voluntarily received three different PoCUS training sessions, each lasting three hours. Prior to the sessions, participants prepared independently with pre-circulated online learning materials. After a 15-minute lecture, experienced PoCUS providers led small group (1 instructor: 5 students), live scanning sessions. Evaluations were conducted before and after each session using expert validated multiple choice questions testing general and procedural knowledge, image recognition and interpretation. Volunteer students were evaluated via direct observation of live scanning using an objective structured assessment of technical skills (OSAT) based on the O-score and then re-evaluated at 2 months post-training to assess PoCUS skills retention. Results: 40 second year medical students participated in extended Focused Assessment with Sonography for Trauma (eFAST), cardiac, and gallbladder PoCUS sessions. The live-training sessions significantly improved student PoCUS knowledge beyond what they learned independently for eFAST (p < 0.001), cardiac (p < 0.001), and gallbladder (p = 0.02). The largest improvement was noted in procedural knowledge test scores improving from 44.0% to 84.0% (n = 38). 16 students were evaluated after each session with a mean O-score of 2.37. 8 students returned two months later to be re-evaluated demonstrating a change in O-scores for eFAST (2.00 to 2.38, p = 0.15), cardiac (2.28 to 2.00, p = 0.32), and gallbladder (2.91 to 1.88, p < 0.001). Conclusion: Procedural PoCUS knowledge benefited the most with hands-on training. eFAST and cardiac PoCUS competency was maintained over time while gallbladder PoCUS competency degraded suggesting that targeted PoCUS skills training may be possible. Further study is required to determine the best use of PoCUS resources in undergraduate medical education.
Leading sociologists who live and work in East Asia examine their region's most dangerous and explosive social problems, and some of their most stunning success stories, from the viewpoint of Civil Sphere Theory. This new and increasingly influential sociological understanding of democracy aims to describe and explain the moral codes and institutional foundations of democratic solidarity, as it manifests itself within a distinct social sphere. Part of a multi-volume project, this collection includes cases from Japan, mainland China, Hong Kong, Taiwan, and South Korea, bringing together efforts by sociologists based in East Asian academic institutions. Through an extraordinary blend of sophisticated social theory and path-breaking empirical research, The Civil Sphere in East Asia aims to advance civil sphere theory by globalizing and regionalizing it at the same time.
This study aimed to determine the relationship between laryngopharyngeal reflux and dietary modification.
A systematic review was conducted. The data sources for the study were PubMed, Embase, Cochrane Library and Web of Science. Articles were independently extracted by two authors according to inclusion and exclusion criteria. The outcome focus was laryngopharyngeal reflux improvement through diet or dietary behaviour.
Of the 372 studies identified, 7 met our inclusion criteria. In these seven studies, laryngopharyngeal reflux symptoms improved following dietary modifications. However, the studies did not present the independent effect of each dietary factor on laryngopharyngeal reflux. Moreover, only one of the seven studies had a randomised controlled study design.
The reference studies of dietary modification for laryngopharyngeal reflux patients are not sufficient to provide recommendations.
In June 2012, the Botswana Ministry of Health and Wellness (MOHW; Gaborone, Botswana) initiated a national Emergency Medical Services (EMS) system in response to significant morbidity and mortality associated with prehospital emergencies. The MOHW requested external expertise to train its developing workforce. Simulation-based training was planned to equip these health care providers with clinical knowledge, procedural skills, and communication techniques.
The objective of this study was to assess the educational needs of the pioneer Botswana MOHW EMS providers based on retrospective EMS logbook review and EMS provider feedback to guide development of a novel educational curriculum.
Data were abstracted from a representative sample of the Gaborone, Botswana MOHW EMS response log from 2013-2014 and were quantified into the five most common call types for both adults and children. Informal focus groups with health professionals and EMS staff, as well as surveys, were used to rank common response call types and self-perceived educational needs.
Based on 1,506 calls, the most common adult response calls were for obstetric emergencies, altered mental status, gastrointestinal/abdominal pain, trauma, gynecological emergencies, and cardiovascular and respiratory distress-related emergencies. The most common pediatric response calls were for respiratory distress, gastrointestinal complaints/dehydration, trauma and musculoskeletal injuries, newborn delivery, seizures, and toxic ingestion/exposure. The EMS providers identified these same chief complaints as priorities for training using the qualitative approach. A locally relevant, simulation-based curriculum for the Botswana MOHW EMS system was developed and implemented based on these data.
: Trauma, respiratory distress, gastrointestinal complaints, and puerperal/perinatal emergencies were common conditions for all age groups. Other age-specific conditions were also identified as educational needs based on epidemiologic data and provider feedback. This needs assessment may be useful when designing locally relevant EMS curricula in other low-income and middle-income countries.GlombNW, KosokoAA, DoughtyCB, RusMC, ShahMI, CoxM, GalapiC, ParkesPS, KumarS, LabaB.Needs Assessment for Simulation Training for Prehospital Providers in Botswana.

During the summer of 2016, the Hawaii Department of Health responded to the second-largest domestic foodborne hepatitis A virus (HAV) outbreak in the post-vaccine era. The epidemiological investigation included case finding and investigation, sequencing of RNA positive clinical specimens, product trace-back and virologic testing and sequencing of HAV RNA from the product. Additionally, an online survey open to all Hawaii residents was conducted to estimate baseline commercial food consumption. We identified 292 confirmed HAV cases, of whom 11 (4%) were possible secondary cases. Seventy-four (25%) were hospitalised and there were two deaths. Among all cases, 94% reported eating at Oahu or Kauai Island branches of Restaurant Chain A, with 86% of those cases reporting raw scallop consumption. In contrast, a food consumption survey conducted during the outbreak indicated 25% of Oahu residents patronised Restaurant Chain A in the 7 weeks before the survey. Product trace-back revealed a single distributor that supplied scallops imported from the Philippines to Restaurant Chain A. Recovery, amplification and sequence comparison of HAV recovered from scallops revealed viral sequences matching those from case-patients. Removal of product from implicated restaurants and vaccination of those potentially exposed led to the cessation of the outbreak. This outbreak further highlights the need for improved imported food safety.
Although many mental health care systems provide care interventions that are not related to direct health care, little is known about the interfaces between the latter and core health care. ‘Core health care’ refers to services whose explicit aim is direct clinical treatment which is usually provided by health professionals, i.e., physicians, nurses, psychologists. ‘Other care’ is typically provided by other staff and includes accommodation, training, promotion of independence, employment support and social skills. In such a definition, ‘other care’ does not necessarily mean being funded or governed differently. The aims of the study were: (1) using a standard classification system (Description and Evaluation of Services and Directories in Europe for Long Term Care, DESDE-LTC) to identify ‘core health’ and ‘other care’ services provided to adults with mental health problems; and (2) to investigate the balance of care by analysing the types and characteristics of core health and other care services.
The study was conducted in eight selected local areas in eight European countries with different mental health systems. All publicly funded mental health services, regardless of the funding agency, for people over 18 years old were identified and coded. The availability, capacity and the workforce of the local mental health services were described using their functional main activity or ‘Main Types of Care’ (MTC) as the standard for international comparison, following the DESDE-LTC system.
In these European study areas, 822 MTCs were identified as providing core health care and 448 provided other types of care. Even though one-third of mental health services in the selected study areas provided interventions that were coded as ‘other care’, significant variation was found in the typology and characteristics of these services across the eight study areas.
The functional distinction between core health and other care overcomes the traditional division between ‘health’ and ‘social’ sectors based on governance and funding. The overall balance between core health and other care services varied significantly across the European sites. Mental health systems cannot be understood or planned without taking into account the availability and capacity of all services specifically available for this target population, including those outside the health sector.
