A Mediterranean-Diet-Based Nutritional Intervention for Children with Prediabetes in a Rural Town: A Pilot Randomized Controlled Trial.

Prediabetes is a pathological condition in which the blood glucose concentration is higher than normal concentrations but lower than those considered necessary for a type 2 diabetes mellitus diagnosis. Various authors have indicated that the Mediterranean Diet is one of the dietary patterns with the most healthy outcomes, reducing high levels of HbA1c, triglycerides, BMI, and other anthropometric parameters. The main objective of this study was to determine the efficacy of the nutritional intervention for children with prediabetes, including the effectiveness of this nutritional education regarding anthropometric parameters. A randomized pilot trial with two groups, an experimental group (EG) and a control group (CG), using intervention in dietary habits with nutritional reinforcement was carried out on 29 children with prediabetes from a rural area. The nutritional intervention was analyzed through astrophotometric and glycemic measurements and validated surveys. Results: The results indicated improvement in eating habits, adherence to the Mediterranean diet, anthropometric measurements, mainly body mass index and perimeters, and analytical parameters, with a significant decrease in glycated hemoglobin in the EG compared to the CG (p < 0.001). Although the results showed that both groups' anthropometric parameters improved, a more significant decrease was observed in the experimental group compared to the control.

Clinical Presentation of the SARS-CoV-2 Virus Infection and Predictive Validity of the PCR Test in Primary Health Care Worker Patients of the Spanish National Health System.

BACKGROUND: Despite the impact that the SARS-CoV-2 virus infection has presented in Spain, data on the diagnostic capacity of the symptoms associated with this infection are limited, especially among patients with mild symptoms and who are detected in the primary care field (PC). The objective of the present study was to know the associated symptoms and their predictive criterial validity in SARS-CoV-2 infection among professionals working in PC. METHODS: A cross-sectional, multicenter study was carried out in the Spanish National Health System, through an epidemiological survey directed to patients who underwent the PCR test for SARS-CoV-2 in the PC setting. RESULTS: A total of 1612 patients participated, of which 86.6% were PC healthcare professionals, and of these, 67.4% family doctors. Hyposmia, with a sensitivity of 42.69% (95% CI: 37.30-48.08) and a specificity of 95.91% (95% CI: 94.78-97.03), and ageusia with a sensitivity of 39.47% (34.15-44.80) and a specificity of 95.20% (93.98-96.41) were the symptoms with the highest criteria validity indexes. CONCLUSIONS: This study identifies the specific symptoms of loss of smell or taste as the most frequently associated with SARS-CoV-2 infection, essential in the detection of COVID-19 given its high frequency and predictive capacity.

Analysis of health habits, vices and interpersonal relationships of Spanish adolescents, using SEM statistical model.

The objective of this article is to know the state of health of a sample of adolescents and how it relates to toxic habits and personal relationships. Likewise, it is presented how can influence eating habits, sports practice and interpersonal relationships in their general health status. The research has carried out through a survey of 56 questions to 470 adolescents, between 13 and 18 years old, of both sexes, of different schools in the province of Cordoba, Spain. These results have been subjected to a statistical model widely used in health and social sciences in general, called Structural Equations Model (SEM), through the SPSS program, v. 23 and AMOS. SEM is widely used in the social sciences to estimate regression models (usually multi-equational). The estimated model shows a significant global acceptability based on the usual statistical tests and goodness-of-fit measures. In this regard, these results are: CMIN = 17.554 with 33 degrees of freedom (DF) and a probability level, p = 0.987, which is higher than any reasonable level of significance (α = 0.05, 0.10, even 0.20). Likewise, FMIN = 0.038, CFI = 1.000 and RMSEA = 0.000. The main recommendation of this research aimed at improving good eating and healthy habits, and to avoid toxic habits of adolescents, is to begin the education in the family, in coordination with their school and high school.

Paciente consumidor de cocaína que presenta disnea / Cocaine using patient who presents with dyspnoea

Se presenta el caso de un paciente varón de 17 años de edad con antecedente de consumo de cocaína, quien consulta por dolor torácico y disnea. El neumomediastino se define como la irrupción de aire en el espacio mediastínico, siendo asociado a diferentes causas, entre ellas las adicciones a drogas inhaladas. Se produce en personas con factores predisponentes y en presencia de factores desencadenantes, como el consumo de drogas inhaladas. La radiografía y la tomografía axial computarizada de tórax son herramientas de gran utilidad para orientar el diagnóstico. La baja incidencia de esta patología representa un diagnóstico difícil para el médico, aunque en algunos ambientes de trabajo característico es necesario un alto nivel de sospecha

We present the case of a 17-year-old male patient with a history of cocaine use who consulted for chest pain and dyspnoea. A pneumomediastinum is defined as the irruption of air in the mediastinal space, and is associated with different causes, including addiction to inhaled drugs. It occurs in people with predisposing factors and the presence of precipitating factors such as consumption of inhaled drugs. X-ray and computed tomography of the thorax are very useful tools in guiding the diagnosis. The low incidence of this pathology represents a difficult diagnosis for the doctor, although in some characteristic work environments a high level of suspicion is necessary
