Rationale: A 'patient-oriented' research paradigm, also known as patient and public engagement, has infiltrated the field of health sciences and continues to spread. At first blush, it is difficult to reprove anything labelled 'patient-oriented'; however, the patient-oriented paradigm may easily become an ideological 'good', leading to unintended consequences that may well prove more detrimental than beneficial. While patient-oriented research has its roots in more radical forms of patient and public engagement, its recent instantiation betrays its roots and forecloses on more radical forms of engagement, such as critical participatory research., Aim and Objectives: The objective of this article is to deconstruct the patient-oriented research narrative and to demonstrate how such a discourse imposes itself as a dominant approach in health sciences., Approach: Following Derrida's deconstructive approach, we bring to light the unexamined presuppositions, false pretences, and presumed 'goodness' and 'naturalness' of patient-oriented discourse., Discussion: By deconstructing the patient-oriented narrative we demonstrate how pre-existing power structures (biomedical, economic, etc.) shape the conduct of the approach and serve to depoliticize the truly participatory aspects of research. Rather than being modelled on the evidence-based movement or seen as its natural 'evolution', patient-oriented research should resist by affirming itself as a radical form that is both participatory and emancipatory., (© 2023 The Authors.

Phenomenon: While part-time clinical work options are popular for physicians, part-time residency training is uncommon. Some residency training programs have offered trainees the option to complete their training on a modified schedule in the past. These part-time tracks often involved extending training in order to complete equivalent hours on a part-time basis. Having experience with trainees in such programs, we sought to explore the impact of completing residency training part-time on the professional and private lives of physicians. Approach: Between 2019 and 2020, we conducted interviews with physicians who completed portions of their residency training part-time between 1995 and 2005 in our institution's pediatrics, combined medicine-pediatrics, and family medicine programs. Findings: Seven female physicians who completed at least some portion of residency part-time were interviewed. To better characterize their experiences, we chose phenomenology as our analytic framework. Members of the research team independently coded each interview and met to resolve conflicts. Codes were then combined and discussed to determine four overarching themes as reasons and benefits of part-time training: The pursuit of extended-time training, logistics, effects on career trajectory, and wellness. These themes highlighted the utility of part-time training and the need for programmatic support to ensure their success. Insights: Based on our findings, adaptability for training and a sense of agency from their part-time experiences persisted throughout interviewees' careers. Each felt empowered to make career choices that fit their personal and professional needs. These findings suggest further investigation into the benefits of offering time-variable training in residency programs.

This article explores the prominent medical theories in Western Europe, paying attention to how these theoretical frameworks changed perceptions of consuming food. It discusses the idea of moderation of food and drink and how it connected to the practice of Protestantism in the household. Finally, the article explores Scottish domestic papers dating from the seventeenth and eighteenth centuries, focusing on recipe books. Through these sources, this article will highlight the historical ties between food and medicine and how it was understood in the upper-class Scottish households.

The rapid increase of interest in, and use of, artificial intelligence (AI) in computer applications has raised a parallel concern about its ability (or lack thereof) to provide understandable, or explainable, output to users. This concern is especially legitimate in biomedical contexts, where patient safety is of paramount importance. This position paper brings together seven researchers working in the field with different roles and perspectives, to explore in depth the concept of explainable AI, or XAI, offering a functional definition and conceptual framework or model that can be used when considering XAI. This is followed by a series of desiderata for attaining explainability in AI, each of which touches upon a key domain in biomedicine., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

Objectives: The health care system faces ongoing challenges due to low-value care. Building on the first pediatric hospital medicine contribution to the American Board of Internal Medicine Foundation Choosing Wisely Campaign, a working group was convened to identify additional priorities for improving health care value for hospitalized children., Methods: A study team composed of nominees from national pediatric medical professional societies was convened, including pediatric hospitalists with expertise in clinical care, hospital leadership, and research. The study team surveyed national pediatric hospitalist LISTSERVs for suggestions, condensed similar responses, and performed a literature search of articles published in the previous 10 years. Using a modified Delphi process, the team completed a series of structured ratings of feasibility and validity and facilitated group discussion. The sum of final mean validity and feasibility scores was used to identify the 5 highest priority recommendations., Results: Two hundred seven respondents suggested 397 preliminary recommendations, yielding 74 unique recommendations that underwent evidence review and rating. The 5 highest-scoring recommendations had a focus on the following aspects of hospital care: (1) length of intravenous antibiotic therapy before transition to oral antibiotics, (2) length of stay for febrile infants evaluated for serious bacterial infection, (3) phototherapy for neonatal hyperbilirubinemia, (4) antibiotic therapy for community-acquired pneumonia, and (5) initiation of intravenous antibiotics in infants with maternal risk factors for sepsis., Conclusions: We propose that pediatric hospitalists can use this list to prioritize quality improvement and scholarly work focused on improving the value and quality of patient care for hospitalized children., Competing Interests: POTENTIAL CONFLICT OF INTEREST: Dr Schondelmeyer discloses funding from the Agency for Healthcare Research and Quality; the National Heart, Lung, and Blood Institute; and the Association for the Advancement of Medical Instrumentation Foundation; the other authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2021 by the American Academy of Pediatrics.)

Objectives: Students from lower socio-economic status backgrounds continue to be under-represented in medical education. Although various initiatives have been implemented by universities to widen participation, their effectiveness and their timing remain contentious. Prior studies have primarily focused on students already on a medical pathway, with little analytical attention given to the aspirations of primary and secondary school-aged students. The aim of this study was to identify the characteristics of students who express early interest in medicine and ascertain the degree to which diversification of the future medical student cohort is indicated., Methods: As part of a longitudinal study of educational and occupational aspirations (2012-2015), students in Years 3-12 (n = 6492) from government schools in New South Wales, Australia, completed an annual online survey. Their individual responses were linked with prior academic achievement and demographic data. Logistic regression models were used to examine the significance of student- and school-related variables as predictors of interest in medicine., Results: Significant predictors were: being in the early years of secondary school, possessing high cultural capital, coming from a language background other than English, being female, and perceiving oneself as 'well above average' relative to peers. Socio-economic status was a significant predictor when examined independently, but not when all variables were considered in the full regression model., Conclusions: For medical schools seeking to widen participation, this study underscores the importance of recognising the intersection of other factors with socio-economic status and how they contribute to students' aspirational biographies. If medical schools are to select from a more diverse range of applicants, recruitment strategies must take into account the discursive positioning of the discipline. Sustained outreach into primary and secondary schools may be critical to interrupting the current social reproduction of medical schooling., (© 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.)

Background: The prevalence of atrial fibrillation (AF) continues to increase; however, there are limited data describing the division of care among practitioners in the community and whether care differs depending on provider specialty., Methods and Results: Using the Outcomes Registry for Better Informed Treatment of AF (ORBIT-AF) Registry, we described patient characteristics and AF management strategies in ambulatory clinic practice settings, including electrophysiology (EP), general cardiology, and primary care. A total of 10 097 patients were included; of these, 1544 (15.3%) were cared for by an EP provider, 6584 (65.2%) by a cardiology provider, and 1969 (19.5%) by an internal medicine/primary care provider. Compared with those patients who were cared for by cardiologists or internal medicine/primary care providers, patients cared for by EP providers were younger (median age, 73 years [interquartile range, IQR, 64, 80 years, Q1, Q3] versus 75 years [IQR, 67, 82 years] for cardiology and versus 76 years [IQR, 68, 82 years] for primary care). Compared with cardiology and internal medicine/primary care providers, EP providers used rhythm control (versus rate control) management more often (44.2% versus 29.7% and 28.8%, respectively, P<0.0001; adjusted odds ratio [OR] EP versus cardiology, 1.66 [95% confidence interval, CI, 1.05 to 2.61]; adjusted OR for internal medicine/primary care versus cardiology, 0.91 [95% CI, 0.65 to 1.26]). Use of oral anticoagulant therapy was high across all providers, although it was higher for cardiology and EP providers (overall, 76.1%; P=0.02 for difference between groups)., Conclusions: Our data demonstrate important differences between provider specialties, the demographics of the AF patient population treated, and treatment strategies-particularly for rhythm control and anticoagulation therapy.

Background and Objectives: Exposure to non-constructive criticism of medical specialties is believed to be fairly common among medical students. Better understanding of this "bashing" phenomenon is needed to promote greater professionalism in medical education and student interest in primary care careers. This study examines exposure and reactions to bashing among third-year medical students in a public university., Methods: A survey assessing amount, sources, targets, and nature of perceived bashing was completed by 105 students. Three open-ended questions elicited students' experiences, opinions, and recommendations., Results: Students perceived that bashing of other specialties occurred during all clerkships; the most were perceived during the surgery clerkship, for which 87.5% reported such bashing. Specialties perceived as the object of bashing were family medicine (72%), general internal medicine (40%), psychiatry (39%), and general surgery (36%). Sixty-seven percent of students reported personally receiving non-constructive criticism about their preferred specialty. Seventy-nine percent believed bashing was unprofessional behavior. Strategies suggested by respondents to decrease bashing included increasing awareness, highlighting the interdisciplinary nature of medicine, and evaluating professionalism., Conclusions: Medical students perceived bashing of medical specialties, recognized it as unprofessional behavior, and would be receptive to interventions to reduce bashing. Findings suggest a need to address bashing as part of professionalism curricula in medical training.

Students recently graduating from the University of Oklahoma College of Medicine are leaving the state for their postgraduate training and entering nonprimary care fields in increasing numbers. This study identifies the major determinants for training location as having to do with the anticipated quality of the program, and for specialty as having to do with positive experiences on clerkship and the perceived characteristics of the field, including potential controllability of practice. Other factors of significance include lifestyle, standard of living and opinions of others. A striking finding was the negative view of Oklahoma held by our graduates.

Although physicians play a major role in dealing with potentially suicidal individuals, little research has been conducted to assess physicians' knowledge of who may or may not present a suicidal risk. The authors in this article present data on the ability of 202 physicians to recognize well established signs of suicide potential. Physicians in 14 areas of medical specialization completed a 13-item, multiple-choice examination of components taken from a suicide potential rating scale. The results revealed that certain groups of physicians predictably scored highest (for example, psychiatrists) but that most physicians were equally knowledgeable about the signs studied.

Work-integrated learning (WIL) for students studying medical laboratory science (MLS) provides hands-on experience that prepares graduates for entry into the pathology workforce. This study explored the student perceptions of studying MLS, before and after WIL placement in a pathology service, and the associated employment opportunities in a pathology laboratory. The WIL pathology technician model enabled students to gain experience across regional and metropolitan locations within the state of Queensland, Australia. With nearly two thirds of graduates employed in the profession and a quarter continuing further education in this field, this program was regarded as a success and helps meet the needs of a growing population with an expectancy of high quality health care. Discussed in this paper is the unique role of the pathology industry working with a regional university to develop successful graduates for a career in pathology, with a focus on the impact of WIL.

Introducción: Las porfirias hepáticas agudas son un trastorno genético causado por actividad irregular en la síntesis del grupo hemo. Aunque son de baja incidencia, su presencia puede aumentar el riesgo de muerte y afectar la calidad de vida de los pacientes. Se realizó una búsqueda bibliográfica con un intervalo desde el año 2015 al 2020, sobre porfirias hepáticas agudas. Objetivos: Actualizar sobre las alternativas diagnósticas y terapéuticas para las porfirias hepáticas agudas en adultos. Desarrollo: La exposición a ciertos factores precipitantes como fármacos, infecciones y estrés, conllevan a una crisis aguda de porfiria, que desencadenan síntomas neuroviscerales y requiere hospitalización. Existen teorías aisladas que explican el mecanismo de daño durante el ataque agudo, como la hiperactividad autónoma, inflamación, disfunción endotelial, mitocondrial, lesión renal y neurotoxicidad. Sin embargo, el reconocimiento clínico de estos mecanismos sin un diagnóstico conocido de porfiria es un reto para el personal médico, debido a la presencia de síntomas y signos inespecíficos, lo que retrasa el diagnóstico. Debido a la dependencia de la hemina de por vida, se han optado por nuevas alternativas terapéuticas como la supresión genética y el trasplante hepático. El pronóstico es favorable cuando se realiza el diagnóstico a tiempo. Conclusiones: Las alternativas diagnósticas y terapéuticas para las porfirias hepáticas agudas en adultos han evolucionado hacia el trasplante ortotópico hepático y la terapia génica, la cual se ha convertido en un enfoque terapéutico prometedor y validado para el tratamiento de los pacientes con porfirias hepáticas.

BackgroundImpairments of the forearm, wrist, and hand affect a sizable proportion of individuals and impose a significant economic burden on health care systems. FEPSim is a medical device for hand and wrist rehabilitation. The FEPSim device could be part of the standard of care for upper extremity rehabilitation during therapeutic activities to increase range of motion, dexterity, and strength. FEPSim has not yet been tested in a health care setting; therefore, a trial of the effectiveness of FEPSim in upper extremity rehabilitation is warranted. ObjectiveThis study aims to assess the feasibility of conducting a definitive trial in terms of recruitment, eligibility criteria, the type and number of diagnoses included, the length and dosage of the intervention, and data collection methods. This study also aims to gather clinical and statistical information as well as information related to the cost and usability, which allows for an economic evaluation of the device. MethodsThe trial will use a randomized controlled design comprising 47 intervention participants and 47 control group participants. Participants will be adults (age≥18 years) attending outpatient rehabilitation with limitations in their forearm, wrist, or hand function due to distal radial or ulnar fractures, stroke, or osteoarthritis. This study’s primary outcome variables are related to patients’ range of motion and strength, specifically active and passive wrist flexion and extension range of motion; active and passive forearm pronation and supination range of motion; grip strength; and pinch strength. The secondary outcome variables are related to patients’ perceived wrist pain and disability in activities of daily living. The patients’ perceived wrist pain and disability in activities of daily living will be measured using the patient-rated wrist evaluation questionnaire. The control group will receive the standard of care at each of the 2 hospital facilities (Glenrose Rehabilitation and Royal Alexandra Hospitals). The intervention group will receive the same standard of care as the control group at each facility and will use the FEPSim device for therapeutic activities to increase strength, range of motion, resistance, and dexterity. All the participants will be assessed at baseline (week 0); weeks 2, 4, and 8; and postintervention (week 10). ResultsThe FEPSim study was launched in April 2020. This study is currently on hold because of the global COVID-19 pandemic. The recruitment process is expected to resume by September 2020, and the primary impact analysis is expected to be conducted by December 2020. ConclusionsThis study will provide valuable information on the measurement of comparative intervention effects, technology acceptance by hand therapists, and how associated treatment and product costs will contribute to the evidence planning process, which will be crucial for the future adoption of FEPSim.

BackgroundThe COVID-19 pandemic has accelerated the worldwide need for simple remotely delivered (digital) scalable interventions that can also be used preventatively to protect the mental health of health care staff exposed to psychologically traumatic events during their COVID-19–related work. We have developed a brief behavioral intervention that aims to reduce the number of intrusive memories of traumatic events but has only been delivered face-to-face so far. After digitalizing the intervention materials, the intervention was delivered digitally to target users (health care staff) for the first time. The adaption for staff’s working context in a hospital setting used a co-design approach. ObjectiveThe aims of this mixed method exploratory pilot study with health care staff who experienced working in the pandemic were to pilot the intervention that we have digitalized (for remote delivery and with remote support) and adapted for this target population (health care staff working clinically during a pandemic) to explore its ability to reduce the number of intrusive memories of traumatic events and improve related symptoms (eg, posttraumatic stress) and participant’s perception of their functioning, and to explore the feasibility and acceptability of both the digitalized intervention and digitalized data collection. MethodsWe worked closely with target users with lived experience of working clinically during the COVID-19 pandemic in a hospital context (registered nurses who experienced intrusive memories from traumatic events at work; N=3). We used a mixed method design and exploratory quantitative and qualitative analysis. ResultsAfter completing the digitalized intervention once with remote researcher support (approximately 25 minutes) and a brief follow-up check-in, participants learned to use the intervention independently. All 3 participants reported zero intrusive memories during week 5 (primary outcome: 100% digital data capture). Prior to study inclusion, two or more intrusions in the week were reported preintervention (assessed retrospectively). There was a general pattern of symptom reduction and improvement in perceived functioning (eg, concentration) at follow-up. The digitalized intervention and data collection were perceived as feasible and rated as acceptable (eg, all 3 participants would recommend it to a colleague). Participants were positive toward the digital intervention as a useful tool that could readily be incorporated into work life and repeated in the face of ongoing or repeated trauma exposure. ConclusionsThe intervention when delivered remotely and adapted for this population during the pandemic was well received by participants. Since it could be tailored around work and daily life and used preventatively, the intervention may hold promise for health care staff pending future evaluations of efficacy. Limitations include the small sample size, lack of daily intrusion frequency data in the week before the intervention, and lack of a control condition. Following this co-design process in adapting and improving intervention delivery and evaluation, the next step is to investigate the efficacy of the digitalized intervention in a randomized controlled trial.

BackgroundManaging type 2 diabetes (T2D) requires progressive lifestyle changes and, sometimes, pharmacological treatment intensification. General practitioners (GPs) are integral to this process but can find pharmacological treatment intensification challenging because of the complexity of continually emerging treatment options. ObjectiveThis study aimed to use a co-design method to develop and pretest a clinical decision support (CDS) tool prototype (GlycASSIST) embedded within an electronic medical record, which uses evidence-based guidelines to provide GPs and people with T2D with recommendations for setting glycated hemoglobin (HbA1c) targets and intensifying treatment together in real time in consultations. MethodsThe literature on T2D-related CDS tools informed the initial GlycASSIST design. A two-part co-design method was then used. Initial feedback was sought via interviews and focus groups with clinicians (4 GPs, 5 endocrinologists, and 3 diabetes educators) and 6 people with T2D. Following refinements, 8 GPs participated in mock consultations in which they had access to GlycASSIST. Six people with T2D viewed a similar mock consultation. Participants provided feedback on the functionality of GlycASSIST and its role in supporting shared decision making (SDM) and treatment intensification. ResultsClinicians and people with T2D believed that GlycASSIST could support SDM (although this was not always observed in the mock consultations) and individualized treatment intensification. They recommended that GlycASSIST includes less information while maintaining relevance and credibility and using graphs and colors to enhance visual appeal. Maintaining clinical autonomy was important to GPs, as they wanted the capacity to override GlycASSIST’s recommendations when appropriate. Clinicians requested easier screen navigation and greater prescribing guidance and capabilities. ConclusionsGlycASSIST was perceived to achieve its purpose of facilitating treatment intensification and was acceptable to people with T2D and GPs. The GlycASSIST prototype is being refined based on these findings to prepare for quantitative evaluation.

Introduction: The objective of this study was to compare long-term neurological outcomes in low-risk patients with traumatic intracranial hemorrhage (tICH) admitted to the ICU (intensive care unit) versus patients admitted to the floor. Methods: This retrospective study was conducted at a Level 1 trauma center from October 1, 2008, to February 1, 2013. We defined low-risk patients as age less than 65 years, isolated head injury, normal admission mental status, and no shift or swelling on initial head CT (computed tomography). Clinical data were abstracted from a trauma registry and linked to a brain injury database. We compared the Extended Glasgow Outcome Scale (GOS-E) score at six months between patients admitted to the ICU and patients admitted to the floor. We did a risk-adjusted analysis of the influence of floor admission on a normal GOS-E. Results: We identified 151 patients; 45 (30%) were admitted to the floor and 106 (70%) to the ICU. Twenty-three (51%; 95% CI [36-66%]) patients admitted to the floor and 55 (52%; 95% CI [42-62%]) patients admitted to the ICU had a normal GOS-E. On adjusted analysis; the odds ratio for floor admission was 0.77 (95% CI [0.36-1.64]) for a normal GOS-E at six months. Conclusion: Long-term neurological outcomes in low-risk patients with tICH were not markedly different between patients admitted to the ICU and those admitted to the floor. However, we were unable to demonstrate non-inferiority on adjusted analysis. Future work aimed at a larger, prospective cohort may better evaluate the relative impacts of admission type on outcomes.

Introduction: Studies have demonstrated that variables other than duration of symptoms can affect outcomes in children with acute testicular torsion. We examined demographic and logistical factors, including inter-hospital transfer, which may affect outcomes at a tertiary pediatric referral center. Methods: We reviewed charts of all pediatric patients with acute testicular torsion during a five-year period. Data were collected regarding age, insurance type, socioeconomic status, duration of symptoms prior to presentation, transfer status, time of day, time to surgical exploration, and testicular salvage. Results: Our study included 114 patients. Testicular salvage was possible in 55.3% of patients. Thirty-one percent of patients included in the study were transferred from another facility. Inter-hospital transfer did not affect testicular salvage rate. Time to surgery and duration of pain were higher among patients who underwent orchiectomy versus orchidopexy. Patients older than eight years of age were more likely to undergo orchidopexy than those younger than eight (61.5% vs. 30.4%, p=0.01). Ethnicity, insurance type, or time of day did not affect the testicular salvage rates. On multivariate analysis, only duration of symptoms less than six hours predicted testicular salvage (OR 22.5, p

Introduction: Questions surround the appropriate emergency department (ED) disposition of children who have sustained blunt head trauma (BHT). Our objective was to identify physician disposition preferences of children with blunt head trauma (BHT) and varying computed tomography (CT) findings.Methods: We surveyed pediatric and general emergency physicians (EP), pediatric neurosurgeons (PNSurg), general neurosurgeons (GNSurg), pediatric surgeons (PSurg) and trauma surgeons regarding care of two hypothetical patients: Case 1: a 9-year-old who fell 10 feet and Case 2: an 11-month-old who fell 5 feet. We presented various CT findings and asked physicians about disposition preferences. We evaluated predictors of patient discharge using multivariable regression analysis adjusting for hospital and ED characteristics and clinician experience. Pediatric EPs served as the reference group.Results: Of 2,341 eligible surveyed, 715 (31%) responded. Most would discharge children with linear skull fractures (Case 1, 71%; Case 2, 62%). Neurosurgeons were more likely to discharge children with small subarachnoid hemorrhages (Case 1 PNSurg OR 6.87, 95% CI 3.60, 13.10; GNSurg OR 6.54, 95% CI 2.38, 17.98; Case 2 PNSurg OR 5.38, 95% CI 2.64, 10.99; GNSurg OR 6.07, 95% CI 2.08, 17.76). PSurg were least likely to discharge children with any CT finding, even linear skull fractures (Case 1 OR 0.14, 95% CI 0.08, 0.23; Case 2 OR 0.18, 95% CI 0.11, 0.30). Few respondents (

Introduction: Children with blunt abdominal trauma (BAT) are often hospitalized despite no intervention. We identified factors associated with emergency department (ED) disposition of children with BAT and differing computed tomography (CT) findings.Methods: We surveyed pediatric and general emergency physicians (EPs), pediatric and trauma surgeons regarding care of two hypothetical asymptomatic patients: a 9-year-old struck by a slow-moving car (Case 1) and an 11-month-old who fell 10 feet (Case 2). We presented various abdominal CT findings and asked physicians about disposition preferences. We evaluated predictors of patient discharge using multivariable regression analysis, adjusting for hospital and ED characteristics, and clinician experience. Pediatric EPs served as the reference group.Results: Of 2,003 eligible surveyed, 636 (32%) responded. For normal CTs, 99% would discharge in Case 1 and 88% in Case 2. Prominent specialty differences included: for trace intraperitoneal fluid (TIF), 68% would discharge in Case 1 and 57% in Case 2. Patients with TIF were less likely to be discharged by pediatric surgeons (Case 1: OR 0.52, 95% CI 0.32, 0.82; Case 2: OR 0.49, 95% CI 0.30, 0.79). Patients with renal contusions were less likely to be discharged by pediatric surgeons (Case 1: OR 0.55, 95% CI 0.32, 0.95) and more likely by general EPs (Case 1: OR 1.83, 95% CI 1.25, 2.69; Case 2: OR 2.37, 95% CI 1.14, 4.89).Conclusion: Substantial variation exists between specialties in reported hospitalization practices of asymptomatic children after abdominal trauma with minor CT findings. Better evidence is needed to guide disposition decisions. [West J Emerg Med. 2013;14(1):37-46.]

Dual energy x-ray absorptiometry (DXA) is an established technique for the measurement of body composition. Reference values for these variables, particularly those related to fat mass, are necessary for interpretation and accurate classification of those at risk for obesity-related health complications and in need of lifestyle modifications (diet, physical activity, etc.). Currently, there are no reference values available for GE-Healthcare DXA systems and it is known that whole-body and regional fat mass measures differ by DXA manufacturer.To develop reference values by age and sex for DXA-derived fat mass measurements with GE-Healthcare systems.A de-identified sample of 3,327 participants (2,076 women, 1,251 men) was obtained from Ball State University's Clinical Exercise Physiology Laboratory and University of Wisconsin-Milwaukee's Physical Activity & Health Research Laboratory. All scans were completed using a GE Lunar Prodigy or iDXA and data reported included percent body fat (%BF), fat mass index (FMI), and ratios of android-to-gynoid (A/G), trunk/limb, and trunk/leg fat measurements. Percentiles were calculated and a factorial ANOVA was used to determine differences in the mean values for each variable between age and sex.Normative reference values for fat mass variables from DXA measurements obtained from GE-Healthcare DXA systems are presented as percentiles for both women and men in 10-year age groups. Women had higher (p

To develop reference values by age and sex for LM measures using GE-Healthcare DXA systems.A de-identified sample was obtained from Ball State University's Clinical Exercise Physiology Laboratory and University of Wisconsin-Milwaukee's Physical Activity & Health Research Laboratory. DXA scans of 2,076 women and 1,251 men were completed using a GE Lunar Prodigy or iDXA. Percentiles (%ile) were calculated for all variables of interest (LM, LMI, %LM, and ALMI) and a factorial ANOVA was used to assess differences for each variable between 10-year age groups and sex, as well as the interaction between age and sex.Men had higher mean total LM, %LM, LMI, and ALMI than women (p

Objectives: We sought to identify factors associated with need for mechanical ventilation (MV), length of intensive care unit (ICU) stay, length of hospital stay, and poor outcome in injection drug users (IDUs) with wound botulism (WB).Methods: This is a retrospective review of WB patients admitted between 1991-2005. IDUs were included if they had symptoms of WB and diagnostic confirmation. Primary outcome variables were the need for MV, length of ICU stay, length of hospital stay, hospital-related complications, and death.Results: Twenty-nine patients met inclusion criteria. Twenty-two (76%) admitted to heroin use only and seven (24%) admitted to heroin and methamphetamine use. Chief complaints on initial presentation included visual changes, 13 (45%); weakness, nine (31%); and difficulty swallowing, seven (24%). Skin wounds were documented in 22 (76%). Twenty-one (72%) patients underwent mechanical ventilation (MV). Antitoxin (AT) was administered to 26 (90%) patients but only two received antitoxin in the emergency department (ED). The time from ED presentation to AT administration was associated with increased length of ICU stay (Regression coefficient = 2.5; 95% CI 0.45, 4.5). The time from ED presentation to wound drainage was also associated with increased length of ICU stay (Regression coefficient = 13.7; 95% CI = 2.3, 25.2). There was no relationship between time to antibiotic administration and length of ICU stay.Conclusion: MV and prolonged ICU stays are common in patients identified with WB. Early AT administration and wound drainage are recommended as these measures may decrease ICU length of stay.[West J Emerg Med. 2009;10(4):251-256.]

Los especímenes fueron obtenidos de mosquitos silvestres, series e isofamilias de hembras recolectadas en cebos humanos protegidos y fueron identificados en todos sus estadios asociados usando las claves convencionales. A partir de fotografías digitales del ala derecha de 336 ejemplares de las 11 especies se seleccionaron 12 puntos anatómicos. Los puntos se convirtieron en coordenadas, las cuales se procesaron mediante el análisis generalizado de Procrustes. Se obtuvieron variables de tamaño y conformación, las cuales fueron analizadas mediante estadísticas univariadas y multivariadas. Resultados. Las técnicas de morfometría geométrica demuestran que la división en secciones del subgénero Nyssorrhynchus no se correlaciona con la conformación de las alas y demostraron que sólo con 12 puntos anatómicos se logra diferenciar en sus respectivas especies el 97% de los especímenes de la sección Argyritarsis y el 86% de la sección Albimanus del subgénero Nyssorhynchus, de forma cuantitativa y sin ambigüedades. Además, se separaron los individuos de tres especies que habitan en simpatría en el Putumayo, difíciles de discriminar en el estadio de adulto hembra. Conclusión. La mayoría de especies de Anopheles (Nyssorhynchus) presentes en Colombia se pueden diferenciar al utilizar la morfometría geométrica como herramienta de apoyo a las claves convencionales

BackgroundYoung people with type 1 diabetes experience elevated levels of emotional distress that impact negatively on their diabetes self-care, quality of life, and disease-related morbidity and mortality. While the need is great and clinically significant, a range of structural (eg, service availability), psychological (eg, perceived stigma), and practical (eg, time and lifestyle) barriers mean that a majority of young people do not access the support they need to manage the emotional and behavioral challenges of type 1 diabetes. ObjectiveThe aim of this study is to examine the effectiveness of a fully-automated cognitive behavior therapy-based mobile phone and Web-based psychotherapeutic intervention (myCompass) for reducing mental health symptoms and diabetes-related distress, and improving positive well-being in this vulnerable patient group. MethodsA two-arm randomized controlled trial will be conducted. Young people with type 1 diabetes and at least mild psychological distress will be recruited via outpatient diabetes centers at three tertiary hospitals in Sydney, Australia, and referred for screening to a study-specific website. Data will be collected entirely online. Participants randomized to the intervention group will use the myCompass intervention for 7 weeks, while at the same time a control group will use an active placebo program matched to the intervention on duration, mode of delivery, and interactivity. ResultsThe primary outcome will be mental well-being (ie, depression, anxiety, diabetes-related distress, and positive well-being), for which data will be collected at baseline, post-intervention, and after 3 months follow-up. Secondary outcomes will be functional (work and social functioning and diabetes self-care), biochemical measures (HbA1c), and mental health self-efficacy. We aim to recruit 280 people into the study that will be conducted entirely online. Group differences will be analyzed on an intention-to-treat basis using mixed models repeated measures. ConclusionsWe hypothesize that scores on the outcome measures will improve significantly for young people who use the mobile phone and Web-based intervention compared to the control group. myCompass is a public health intervention that is broadly available and free to use. If effective, the program has the capacity to provide convenient and accessible evidenced-based care to the large group of young people with type 1 diabetes who do not currently access the psychosocial support they need.

Introduction: High body mass index (BMI) values generally correlate with a large proportion of intra-peritoneal adipose tissue. Because intra-peritoneal infectious and inflammatory conditions manifest with abnormalities of the adipose tissue adjacent to the inflamed organ, it is presumed that with a larger percentage of adipose surrounding a given organ, visualization of the inflammatory changes would be more readily apparent. Do higher BMI values sufficiently enhance the ability of a radiologist to read a computed tomography of the abdomen and pelvis, so that the need for oral contrast to be given is precluded?Methods: Forty six patients were included in the study: twenty seven females, and nineteen males. They underwent abdominal/pelvic CTs without oral or intravenous contrast in the emergency department. Two board certified radiologists reviewed their CTs, and assessed them for radiographic evidence of intra-abdominal pathology. The patients were then placed into one of four groups based on their body mass index. Kappa analysis was performed on the CT reads for each group to determine whether there was significant inter-rater agreement regarding contrast use for the patient in question.Results: There was increasingly significant agreement between radiologists, regarding contrast use, as the study subject’s BMI increased. In addition, there was an advancing tendency of the radiologists to state that there was no need for oral or intravenous contrast in patients with higher body mass indices, as the larger quantity of intra-peritoneal adipose allowed greater visualization and inspection of intra-abdominal organs.Conclusion: Based on the results of this study, it appears that there is a decreasing need for oral contrast in emergency department patients undergoing abdominal/pelvic CT, as a patient’s BMI increases. Specifically, there was statistically significant agreement, between radiologists, regarding contrast use in patients who had a BMI greater than twenty-five. [West J Emerg Med.2013;14(6):595–597.]

La identificación correcta de las hembras es esencial para el éxito de cualquier estudio de epidemiología, resistencia a insecticidas o de control de vectores. En el departamento del Putumayo, en el sur de Colombia, la transmisión de malaria continúa siendo un problema, a pesar de la ausencia de los vectores principales de Latinoamérica (Anopheles darlingi Root, Anopheles nuneztovari Gabaldón, Anopheles albimanus Wideman, Anopheles trinkae Faran) en esta región. Se recolectaron. con cebo humano, hembras de Anopheles y se encontró una variante morfológica de Anopheles benarrochi, que en su estadio adulto fácilmente se confunde con Anopheles oswaldoi. La identificación de hembras de Anopheles, particularmente del subgénero Nyssorhynchus, es en general notoriamente difícil debido a la superposición de caracteres morfológicos en el estadio adulto; por tanto, las colecciones deben estar ligadas a la cría de material asociado para identificar correctamente las especies. Esto requiere tiempo y es difícil de obtener en muchas ocasiones. Se presenta un método indirecto de identificación de las especies A. benarrochi, A. oswaldoi y Anopheles rangeli del sur de Colombia usando la morfología de los huevos de hembras silvestres. Los huevos de A. rangeli y A. benarrochi se diferencian por la corona anterior, la cual es apical en A. rangeli y con paredes altas, mientras que en A. benarrochi es ventral y con paredes más cortas. Esta corona está ausente en A. oswaldoi. Estas diferencias fueron obvias incluso bajo un microscopio de luz, lo que hace posible una identificación correcta de estas especies en condiciones de campo. Se muestra cómo la observación de la morfología de los huevos puede permitir la determinación taxonómica correcta, aunque indirecta, de estas tres especies de Nyssorhynchus encontradas en el sur de Colombia, el cual puede ser útil también en otras regiones de Latinoamérica, en donde se encuentre la variante morfológica de A. benarrochi en simpatría con A. oswaldoi.

BackgroundAt prevalence rates of up to 40%, rates of depression and anxiety among women with medically complex pregnancies are 3 times greater than those in community-based samples of pregnant women. However, mental health care is not a component of routine hospital-based antenatal care for medically high-risk pregnant women. ObjectiveThe purpose of this study is to evaluate the effectiveness and feasibility of the hospital-based implementation of a Web-based integrated mental health intervention comprising psychosocial assessment, referral, and cognitive behavioral therapy (CBT) for antenatal inpatients. MethodsThis study is a quasi-experimental design. Pregnant women are eligible to participate if they are (1) 72 hours, (3) able to speak and read English or be willing to use a translation service to assist with completion of the questionnaires and intervention, (4) able to complete follow-up email questionnaires, (5) >16 years of age, and (6) not actively suicidal. Women admitted to the unit for induction (eg,

Con el propósito de ampliar el conocimiento sobre las especies de Anopheles presentes en el Putumayo, sur de Colombia, y para esclarecer la identidad de los ejemplares clasificados como Anopheles (Nyssorhynchus) evansae en esta región, se recolectaron mosquitos hembra en cebo humano, se alimentaron en pequeños mamíferos y se mantuvieron vivos para la cría de isofamilias. Se realizaron observaciones de las características morfológicas de los huevos, larvas, pupas y adultos de ambos sexos, incluidas las genitalias masculinas. Se obtuvieron 247 posturas de madres identificadas preliminarmente como A. (N) evansae A 27 de estas familias se les estudió la morfología de los estadios asociados. Todos los especimenes fueron subsecuentemente identificados como Anopheles (N) benarrochi por la morfología de los huevos, larvas, pupas y genitalias masculinas, lo cual coincidió con las descripciones publicadas para esta especie. Sin embargo, los adultos hembra de Putumayo presentaron la proporción oscura en el tarsómero posterior 2, entre 0.17 y 0.33 de su longitud, inferior a lo informado para esta especie, lo cual se superpone con los rangos de Anopheles (N.) oswaldoi y A. (N.) evansae. Como resultado de la superposición en este carácter, es probable que hembras adultas de A. (N.) benarrochi hayan sido incorrectamente identificadas como A. (N) evansae y A. (N.) oswaldoi en el sur de Colombia. La presencia de esta variante morfológica ha dificultado la identificación de A. (N.) benarrochi en Putumayo y, probablemente, en otras regiones de Colombia y paises vecinos.

The purpose of this study was to describe the clinical findings in patients with splenic injury and to determine if isolated left lower chest injury may be the single clinical indicator of splenic injury. The medical records of all adult blunt trauma patients with splenic injury over a 14 month period were reviewed. Significant left lower chest injury was considered present if the patient had left sided pleuritic chest pain with tenderness to ribs 7-12 or if these ribs were visualized as fractured on any imaging study. Patients were considered to have clinical findings suggestive of splenic injury if they had pre-hospital or emergency department hypotension, abdominal pain or tenderness, a Glasgow coma scale < 15, or gross hematuria. Ninety patients had splenic injury. Thirty-nine (43%. 95% CI 33, 54%) patients had significant left lower chest injury. In five (6%. 95% CI 2, 12%) patients, injury to this portion of the chest was the single indicator of splenic injury. Nearly half the patients with splenic injury will have significant injury to the left lower chest and this finding may be the only indicator of splenic injury.
