Embedding sports and exercise medicine into the medical curriculum; a call for inclusion

The UK is currently facing an inactivity crises, with 1 in 5 children currently meeting physical activity guidelines (Health Survey for England, Children’s Health, 2016). To combat this growing problem there has been increased interest in promoting exercise and healthy lifestyle advise to patients as a method for improving public health. In line with this, the specialty of Sports and Exercise Medicine (SEM) has been gaining momentum and is now a recognised specialty with a higher specialist training programme. This postgraduate speciality aims to produce doctors who are experts in exercise and musculoskeletal medicine. Increasing numbers of NHS departments are employing SEM doctors to better manage musculoskeletal (MSK) issues and prescribe exercise (Morrissey et. al, Muscles Ligaments Tendons J 3:190–195, 2013). In keeping with this increased opportunity for SEM in postgraduate training, we believe that we should not forget that SEM should not be exclusive to postgraduates and there is increasing interest and need for teaching to medical students (Cullen et al, Br J Sports Med 34:244-245, 2000). This article provides an overview to students and clinicians into the current state of undergraduate SEM education in the UK, and highlights the importance of incorporating SEM into the medical curricula.     

Histological,Histochemical and Morphometric Changes of Splenic Melanomacrophage Centers (Smmcs) in Sparicotyle-Infected Cultured Sea Breams (Sparus aurata)

Diseases caused by parasites are much more frequently described in cultured fish, which suffer from artificial conditions and numerous stress factors. This study investigates the histological, histochemical and morphometric modifications of splenic melanomacrophage centers (SMMCs) infected by Sparicotyle chrisophrii (Monogenea, ectoparasite of the gills) in sea breams (Sparus aurata), cultured in floating cages in the Gulf of Gaeta (Italy). Infected fish swam near the water surface, showing severe signs of anemia. Several spleens were collected from both healthy and dead fish (70–100 gr. body weight). A spleen histopathology was evaluated by using traditional stainings, such as Haematoxylin and Eosin (HE), Periodic Acid-Schiff reaction (PAS), Perl's reaction for haemosiderin and Schmorl's reaction for lipofuscins. Furthermore, SMMCs morphometry was performed on PAS-stained sections to study 7 morphometric parameters [Mean SMMCs profile area (MPA), Mean SMMCs maximum diameter (Media), Mean SMMCs minimum diameter (media), Mean SMMCs diameter (Dia), Mean SMMCs Perimeter (P), Mean SMMCs Form Factor (FF) and Mean SMMCs number per square millimeter of spleen tissue (MN)]. A light microscope of HE stained sections of spleen revealed a dramatic increase in the size and number of SMMCs in parasitized animals. Morphometric data illustrated statistically significant differences (p < 0.01) of all studied parameters between healthy and diseased fish. This study emphasizes the importance of using histopathological investigations to unravel the complex biological host/parasite interaction, which results in systemic lesions affecting reared marine species.     

Neurodevelopmental Outcomes in Children With Congenital Heart Disease: Evaluation and Management: A Scientific Statement From the American Heart Association

BACKGROUND: The goal of this statement was to review the available literature on surveillance, screening, evaluation, and management strategies and put forward a scientific statement that would comprehensively review the literature and create recommendations to optimize neurodevelopmental outcome in the pediatric congenital heart disease (CHD) population. METHODS AND RESULTS: A writing group appointed by the American Heart Association and American Academy of Pediatrics reviewed the available literature addressing developmental disorder and disability and developmental delay in the CHD population, with specific attention given to surveillance, screening, evaluation, and management strategies. MEDLINE and Google Scholar database searches from 1966 to 2011 were performed for English-language articles cross-referencing CHD with pertinent search terms. The reference lists of identified articles were also searched. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. A management algorithm was devised that stratified children with CHD on the basis of established risk factors. For those deemed to be at high risk for developmental disorder or disabilities or for developmental delay, formal, periodic developmental and medical evaluations are recommended. A CHD algorithm for surveillance, screening, evaluation, reevaluation, and management of developmental disorder or disability has been constructed to serve as a supplement to the 2006 American Academy of Pediatrics statement on developmental surveillance and screening. The proposed algorithm is designed to be carried out within the context of the medical home. This scientific statement is meant for medical providers within the medical home who care for patients with CHD. CONCLUSIONS: Children with CHD are at increased risk of developmental disorder or disabilities or developmental delay. Periodic developmental surveillance, screening, evaluation, and reevaluation throughout childhood may enhance identification of significant deficits, allowing for appropriate therapies and education to enhance later academic, behavioral, psychosocial, and adaptive functioning.     

Subcutaneous adjusted-dose unfractionated heparin vs fixed-dose low-molecular-weight heparin in the initial treatment of venous thromboembolism

BACKGROUND: Few reports have addressed the value of unfractionated heparin (UFH) or low-molecular-weight heparin in treating the full spectrum of patients with venous thromboembolism (VTE), including recurrent VTE and pulmonary embolism. METHODS: In an open, multicenter clinical trial, 720 consecutive patients with acute symptomatic VTE, including 119 noncritically ill patients (16.5%) with pulmonary embolism and 102 (14.2%) with recurrent VTE, were randomly assigned to treatment with subcutaneous UFH with dose adjusted by activated partial thromboplastin time by means of a weight-based algorithm (preceded by an intravenous loading dose), or fixed-dose (adjusted only to body weight) subcutaneous nadroparin calcium. Oral anticoagulant therapy was started concomitantly and continued for at least 3 months. We recorded the incidence of major bleeding during the initial heparin treatment and that of recurrent VTE and death during 3 months of follow-up. RESULTS: Fifteen (4.2%) of the 360 patients assigned to UFH had recurrent thromboembolic events, as compared with 14 (3.9%) of the 360 patients assigned to nadroparin (absolute difference between rates, 0.3%; 95% confidence interval, -2.5% to 3.1%). Four patients assigned to UFH (1.1%) and 3 patients assigned to nadroparin (0.8%) had episodes of major bleeding (absolute difference between rates, 0.3%; 95% confidence interval, -1.2% to 1.7%). Overall mortality was 3.3% in each group. CONCLUSIONS: Subcutaneous UFH with dose adjusted by activated partial thromboplastin time by means of a weight-based algorithm is as effective and safe as fixed-dose nadroparin for the initial treatment of patients with VTE, including those with pulmonary embolism and recurrent VTE.     

Chagas disease in rural areas of Chaco Province, Argentina: epidemiologic survey in humans, reservoirs, and vectors

We studied the seroprevalence of antibodies against Trypanosoma cruzi in the human population along with domiciliary infestation by triatomine bugs in an area endemic for Chagas disease in the Chaco Province of Argentina. In addition, we carried out parasitologic surveys in patients, dogs, wild mammals, and vectors. The mean seroprevalence in humans was 27.81% (109 of 392) and 24.14% (63 of 261) in 1-15-year-old children. The minimum domiciliary infestation rate was 13.33%, with certain areas reaching 53.85%. The prevalence was 15.09% (16 of 106) in dogs and 35.71% (10 of 28) in opossums. Infection with T. cruzi was detected in 30.10% (59 of 196) of the Triatoma infestans tested. Compared with nationwide studies, our data suggest that 1) there are zones requiring immediate sanitary action, and 2) nationwide estimates are based on very heterogeneous epidemiologic situations. This heterogeneity emphasizes the importance of in-depth studies of restricted areas to provide additional information for a better understanding of the present status of Chagas disease in Argentina.
