    Hypercalcemia is a common condition in the internal medicine practice. Sometimes its cause is not readily apparent, so extensive investigation is appropriate. Here we report an unexpected cause for hypercalcemia in an elderly woman. The case of an 82-years old woman with PTH-independent hypercalcemia, lymphocytosis, normal serum 1,25 (OH)vitamin D levels, and low serum PTHrp levels, is described. Medical history and complementary investigation were unremarkable, except for increased metabolic activity in the glutei regions, as measured by whole body 18F-FDG PET-CT. Reviewing her medical history, her sister recalled that she had been submitted to intramuscular methylmethacrylate injections, for cosmetic purposes, five years before presentation, which was confirmed by muscle biopsy. Low calcium intake, parenteral bisphosphonates, calcitonin, and glucocorticoids were used to control serum calcium levels. Methylmethacrylate injections, used cosmetically, are a new cause for hypercalcemia, even after many years. Hypercalcemia was probably due to calcitriol overproduction in foreign body granulomas. Persistent reactive lymphocytosis could be a clue for this inflammatory cause of hypercalcemia

    We aimed to assess if GLP-1 agonists are associated with pancreatic cancer. Systematic review and meta-analysis of randomized trials with GLP-1 agonists as an intervention was performed. Trial sequential analysis (TSA) was performed to assess if the available information is sufficient to reject this association. Twelve trials met the study criteria, with a total of 36, 397 patients. GLP-1 analogues did not increase the risk for pancreatic cancer when compared to other treatments (OR 1.06; 95% CI 0.67 to 1.67; I2 14%). TSA confirmed that enough patients were randomized and again no association of the medications and pancreatic cancer was observed considering a NNH of 1000 and the short mean follow-up of the included trials (1.7 years). Larger studies with longer duration would be required to exclude a greater NNH and to aside concerns regarding possible influence of study duration and the outcome

    The efects of antihyperglycemic medications on cardiovascular events and mortality are heterogeneous and their efects on intermediate factors might explain these diferences. This systematic review explores the relationship between metabolic factors, mechanism of action, and mortality efects of antihyperglycemic medications in type 2 diabetes. Randomized trials assessing the efects of antihyperglycemic medications on all-cause or cardiovascular mortality in type 2 diabetes were included. Myocardial infarction, stroke, and heart failure were secondary outcomes. The efects of medications on HbA1c, severe hypoglycemia (SH), body weight, systolic blood pressure (SBP), and mechanism of action were evaluated. Meta-analyses and meta-regressions were performed grouping studies according to the above-cited factors. All-cause mortality was lower for medications that reduced HbA1c, SH, body weight, and SBP. Decreased cardiovascular mortality was associated with lower HbA1c, SH, SBP. Myocardial infarction and stroke were also associated with favorable metabolic profle. These fndings were not confrmed in meta-regression models. Medications associated with lower SH, body weight and SBP had a lower risk of heart failure. In conclusion, medications with better metabolic profle were associated with reduced all-cause and cardiovascular mortality. These fndings are based on indirect comparisons and must be applied cautiously

    Objective: The mere dissemination of standard care recommendations has been insufficient to improve clinical results in patients with asthma. The objective of the present study was to evaluate the clinical effectiveness of a multifaceted asthma distance education for primary care providers. Methods: Cluster randomized controlled trial. Full primary care teams were included if they had access to telehealth support and free basic asthma treatment. Before randomization, selected teams indicated asthma patients between 5-45 years old for inclusion. The intervention group received three interactive online sessions, printed educational material, reminders, booklet for patients, and frequent stimulus to use consulting services. The control group received no intervention. Symptomfree days per two weeks was the primary result. Controlled asthma, unscheduled asthma doctor visits, and preventive inhaled corticosteroid use were the secondary results. Six months after intervention, the results were compared with baseline data using generalized estimating equations for repeated measures and clustering effect. Results: Were enrolled 71 primary care teams and 443 individuals. Most patients (60.3%) were female, and 44% were younger than 12 years old. The attendance of interactive sessions by the teams was 50%. The odds ratio (OR) for additional symptom-free day was 1.31 (95%CI 0.61-2.82; p=0.49). For the secondary results, the results were: controlled asthma OR 1.29 (95%CI 0.89-1.87; p=0.18); unscheduled asthma doctor visits OR 0.81 (95%CI 0.60-1.10; p=0.17); and preventive inhaled corticosteroid use OR 1.02 (95%CI 0.71-1.47; p=0.91). Conclusions: Multifaceted distance education in asthma care for primary care providers was not effective to improve patients’ results. Telemedicine needs to deal with significant obstacles in professional education.Objetivo: A mera disseminação de recomendações de cuidados padronizados tem sido insuficiente para melhorar os desfechos clínicos em pacientes com asma. O objetivo do presente estudo foi avaliar a eficácia clínica de uma intervenção educativa multifacetada a distância sobre asma para profissionais da atenção primária à saúde. Métodos: Ensaio clínico randomizado por cluster. Equipes completas de atenção primária foram incluídas se tinham acesso a suporte de telessaúde e tratamento básico gratuito para asma. Antes da randomização, as equipes selecionadas indicaram pacientes asmáticos entre 5-45 anos para inclusão. O grupo de intervenção recebeu três sessões online interativas, material educativo impresso, lembretes, folheto para pacientes e estímulos frequentes para o uso de serviços de consultoria. O grupo controle não recebeu intervenção. O desfecho primário foi dias sem sintomas por duas semanas. Asma controlada, consultas médicas não programadas para asma e uso preventivo de corticosteroides inalatórios foram os desfechos secundários. Seis meses após a intervenção, os resultados foram comparados com a linha de base, usando equações de estimativas generalizadas para medidas repetidas e efeito de agrupamento. Resultados: Foram inscritas 71 equipes de atenção primária e 443 indivíduos. A maioria dos pacientes (60,3%) era do sexo feminino e 44% tinha menos de 12 anos de idade. A frequência das equipes nas sessões interativas foi de 50%. O odds ratio (OR) para dias sem sintomas adicionais foi de 1,31 (IC 95% 0,61-2,82; p=0,49). Para os desfechos secundários, os resultados foram: asma controlada 1,29 (IC 95% 0,89-1,87; p=0,18); visitas não programadas de asma ao médico OR 0,81 (IC 95% 0,60-1,10; p=0,17); e uso preventivo de corticosteroides inalatórios OR 1,02 (IC 95% 0,71-1,47; p=0,91). Conclusões: Ações multifacetadas de educação a distância em cuidados de asma para profissionais de saúde da atenção primária não foram eficazes para melhorar os resultados nos pacientes. A telemedicina precisa lidar com obstáculos significativos na educação profissional.Objetivo: La mera difusión de las recomendaciones de atención estándar ha sido insuficiente para mejorar los resultados clínicos en pacientes con asma.

El grupo control no recibió ninguna intervención. El resultado primario fue días sin síntomas por dos semanas. Los resultados secundarios fueron asma controlada, visitas médicas no programadas para el asma y el uso preventivo de corticosteroides inhalados. Seis meses después de la intervención, los resultados se compararon con los datos de referencia utilizando ecuaciones de estimación generalizadas para medidas repetidas y efecto de agrupación. Resultados: Se inscribieron 71 equipos de atención primaria y 443 personas. La mayoría de los pacientes (60,3%) eran mujeres y el 44% eran menores de 12 años. La asistencia a sesiones interactivas por parte de los equipos fue del 50%. La razón de probabilidades (OR) para un día sin síntomas adicional fue de 1.31 (IC del 95%: 0.61 a 2.82; p=0.49). Para los resultados secundarios, los resultados fueron: asma controlada O 1.29 (IC del 95%: 0.89 a 1.87; p=0.18); visitas al médico para el asma no programadas O 0,81 (IC del 95%: 0,60 a 1,10; p=0,17); y el uso preventivo de corticosteroides inhalados OR 1.02 (IC del 95%: 0.71 a 1.47; p=0.91). Conclusiones: La educación a distancia multifacética en el cuidado del asma para los proveedores de atención primaria no fue efectiva para mejorar los resultados de los pacientes. La telemedicina debe enfrentar obstáculos significativos en la educación profesional.Teleducaçã

    Central venous catheters (CVCs) are frequently used, but the rate of complications is high. This study evaluates the effects of a short training program for CVC insertion in a university-based teaching hospital. A sample of adults with CVCs inserted outside the intensive care unit was selected from two academic years: 2015, year without structured training, and 2016, year with structured training. Clinical and laboratory information, as well as the procedure’s characteristics and complications (mechanical and infectious) were collected. The incidence of complications before and after the training was compared. A total of 1502 punctures were evaluated. Comparing the pre- and post-training period, there was an increase in the choice for jugular veins and the use of ultrasound. A numerical reduction in the rate of complications was identified (RR 0.732; 95% CI 0.48–1.12; P = 0.166). This difference was driven by a statistically significant lower rate of catheter-related infections (RR 0.78; 95% CI 0.64–0.95; P = 0.047). In the multivariate analysis, aspects regarding technique (ultrasound use, multiple punctures) and year of training were associated with outcomes. Structured training reduces the rate of complications related to CVC insertion, especially regarding infections
