Update on the Endoscopic Management of Peptic Ulcer Bleeding

Upper gastrointestinal bleeding is the most common gastrointestinal emergency, with peptic ulcer as the most common cause. Appropriate resuscitation followed by early endoscopy for diagnosis and treatment are of major importance in these patients. Endoscopy is recommended within 24 h of presentation. Endoscopic therapy is indicated for patients with high-risk stigmata, in particular those with active bleeding and visible vessels. The role of endoscopic therapy for ulcers with adherent clots remains to be elucidated. Ablative or mechanical therapies are superior to epinephrine injection alone in terms of prevention of rebleeding. The application of an ulcer-covering hemospray is a new promising tool. High dose proton pump inhibitors should be administered intravenously for 72 h after endoscopy in high-risk patients. Helicobacter pylori should be tested for in all patients with peptic ulcer bleeding and eradicated if positive. These recommendations have been captured in a recent international guideline

Correlates of gross motor competence in children and adolescents: A systematic review and meta-analysis

Background Gross motor competence confers health benefits, but levels in children and adolescents are low. While interventions can improve gross motor competence, it remains unclear which correlates should be targeted to ensure interventions are most effective, and for whom targeted and tailored interventions should be developed. Objective The aim of this systematic review was to identify the potential correlates of gross motor competence in typically developing children and adolescents (aged 3–18 years) using an ecological approach. Methods Motor competence was defined as gross motor skill competency, encompassing fundamental movement skills and motor coordination, but excluding motor fitness. Studies needed to assess a summary score of at least one aspect of motor competence (i.e., object control, locomotor, stability, or motor coordination). A structured electronic literature search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Six electronic databases (CINAHL Complete, ERIC, MEDLINE Complete, PsycINFO, Scopus and SPORTDiscus with Full Text) were searched from 1994 to 5 August 2014. Meta-analyses were conducted to determine the relationship between potential correlates and motor competency if at least three individual studies investigated the same correlate and also reported standardized regression coefficients. Results A total of 59 studies were identified from 22 different countries, published between 1995 and 2014. Studies reflected the full range of age groups. The most examined correlates were biological and demographic factors. Age (increasing) was a correlate of children’s motor competence. Weight status (healthy), sex (male) and socioeconomic background (higher) were consistent correlates for certain aspects of motor competence only. Physical activity and sport participation constituted the majority of investigations in the behavioral attributes and skills category. Whilst we found physical activity to be a positive correlate of skill composite and motor coordination, we also found indeterminate evidence for physical activity being a correlate of object control or locomotor skill competence. Few studies investigated cognitive, emotional and psychological factors, cultural and social factors or physical environment factors as correlates of motor competence. Conclusion This systematic review is the first that has investigated correlates of gross motor competence in children and adolescents. A strength is that we categorized correlates according to the specific ways motor competence has been defined and operationalized (object control, motor coordination, etc.), which enables us to have an understanding of what correlates assist what types of motor competence. Indeed our findings do suggest that evidence for some correlates differs according to how motor competence is operationalized

Hemorragia maciça do intestino grosso: o que está ao nosso alcance? Massive large bowel bleeding: what is within our reach?

A forma de avaliar e lidar com a hemorragia aguda digestiva baixa tem sido modificado com os recentes desenvolvimentos de novas técnicas e aparelhos. O nosso objetivo, por esse manuscrito, é demonstrar com simplicidade uma forma de condução dos pacientes com hemorragia digestiva baixa aguda, sobretudo para os sangramentos que parecem mais graves, principalmente quando nos faltam os recursos das avançadas tecnologias atuais. Doenças localizadas no intestino grosso respondem por ¼ dos casos de hemorragias digestivas que são motivos para admissão hospitalar e têm como principais agentes etiológicos os divertículos, na moléstia diverticular, e as alterações vasculares, nas angiodisplasias. Na grande maioria das vezes o sangramento que pode parecer abundante cessa espontaneamente. Os distúrbios circulatórios graves não são comuns e os sinais mais frequentes são a queda do valor da hemoglobina observada na metade dos pacientes, e algumas alterações hemodinâmicas como a variação pressórica postural que pode ser vista em até 30% dos casos; a síncope em 10% e alguma forma de colapso circulatório, em 9%. Contudo, a faixa etária em que ocorre, as condições da senilidade, as doenças eventualmente associadas e a falta de recursos materiais e humanos para lidar com esse tipo de problema são os motivos que mais causam preocupação. A abordagem clínica simples com uma história bem elaborada; o exame físico com atenção e objetividade, a inclusão do exame proctológico, a obrigatória disponibilidade de aparelho para a coloscopia e os conhecimentos básicos sobre o evento formam o conjunto necessário e, na maioria das vezes, suficiente para o correto desempenho profissional na elaboração dos cuidados que devem ser dados a esses pacientes.<br>The evaluation and management of the acute lower digestive hemorrhage has been modified with the recent development of new techniques and devices. The aim of this manuscript was to demonstrate with simplicity how to treat the patients with acute lower intestinal hemorrhage. Diseases of the large bowel account for the ¼ of the cases of digestive hemorrhages on the hospital admission and have as main etiological agents the diverticula, in the diverticular disease, and small vascular malformation, in the angiodysplasias. Sometime, it can be seen as a life-threatening condition, however, most of the times, the hemorrhage stops spontaneously. The serious circulatory disturbances are not common; the most frequent signs are the decrease in hemoglobin occurring on about one half of patients and some form of circulatory disturbance as orthostatic changes in 30%; as syncope in 10% and as cardiovascular collapse in 9%. However, the age group, the conditions of the senility, the eventually associated diseases and the lack of material and human resources to handle with that kind of problem are the reasons for concern. The simple clinical approach with a well elaborated history; the physical examination released with attention and objectivity, the inclusion of the proctologic exam, the obligatory readiness for an endoscope for colonoscopy, the basic knowledge on the event are necessary and, in most of the times, enough for the good professional acting in the elaboration of the cares that it should be given to those patient ones
