Consenso sobre la detección y el manejo de la prediabetes. Grupo de trabajo de consensos y guías clínicas de la Sociedad Española de Diabetes

En España, según datos del estudio [email protected], un 13,8% de la población adulta padece diabetes y un 14,8% algún tipo de prediabetes (intolerancia a la glucosa, glucemia basal alterada o ambas). Puesto que la detección precoz de la prediabetes puede facilitar la puesta en marcha de medidas terapéuticas que eviten su progresión a diabetes, consideramos que las estrategias de prevención en las consultas de atención primaria y especializada deberían consensuarse. La detección de diabetes y prediabetes mediante un cuestionario específico (test de FINDRISC) y/o la determinación de la glucemia basal en pacientes de riesgo permiten detectar los pacientes con riesgo de desarrollar la enfermedad y es necesario considerar cómo debe ser su manejo clínico. La intervención sobre los estilos de vida puede reducir la progresión a diabetes o hacer retroceder un estado prediabético a la normalidad y es una intervención coste-efectiva. Algunos fármacos, como la metformina, también se han mostrado eficaces en reducir la progresión a diabetes aunque no son superiores a las in tervenciones no farmacológicas. Finalmente, aunque no hay pruebas sólidas que apoyen la eficacia del cribado en términos de morbimortalidad, sí que ha observado una mejora de los factores de riesgo cardiovascular.El Grupo de Trabajo de Consensos y Guías Clínicas de la Sociedad Española de Diabetes (SED) ha elaborado unas recomendaciones que han sido consensuadas con la Sociedad Española de Endocrinología y Nutrición (SEEN), la Sociedad Española de Endocrinología Pediátrica (SEEP), la Sociedad Española de Farmacia Familiar y Comunitaria (SEFAC), la Sociedad Española de Medicina Familiar y Comunitaria (SEMFYC), la Sociedad Española de Médicos Generales (SEMG), la Sociedad Española de Médicos de Atención Primaria (SEMERGEN), la Sociedad Española de Medicina Interna (SEMI), la Asociación de Enfermería Comunitaria (AEC) y la Red de Grupos de Estudio de la Diabetes en Atención Primaria (RedGDPS)

Isolation of Neisseria meningitidis strains with increase of penicillin minimal inhibitory concentrations

We report the isolation and characterization of ten strains showing an increase in the minimal inhibitory concentrations to penicillin (MICs > 0·1 μg/ml), and describe the epidemiological, clinical and microbiological features. The susceptibility of 3432 meningococcal strains isolated from patients in the recent epidemic wave (1978–86) in Spain, to several antimicrobial agents used in the treatment and chemoprophylaxis of meningococcal infection has been tested. Most were resistant to sulphadiazine but sensitive to other antibiotics. The possible existence of a new pattern of behaviour of meningococcal to penicillin is discussed

GW150914: First search for the electromagnetic counterpart of a gravitational-wave event by the TOROS collaboration

We present the results of the optical follow-up conducted by the TOROS collaboration of the first gravitational-wave event GW150914. We conducted unfiltered CCD observations (0.35-1 micron) with the 1.5-m telescope at Bosque Alegre starting ~2.5 days after the alarm. Given our limited field of view (~100 square arcmin), we targeted 14 nearby galaxies that were observable from the site and were located within the area of higher localization probability. We analyzed the observations using two independent implementations of difference-imaging algorithms, followed by a Random-Forest-based algorithm to discriminate between real and bogus transients. We did not find any bona fide transient event in the surveyed area down to a 5-sigma limiting magnitude of r=21.7 mag (AB). Our result is consistent with the LIGO detection of a binary black hole merger, for which no electromagnetic counterparts are expected, and with the expected rates of other astrophysical transients.Comment: ApJ Letters, in pres

Evolution, geographic spreading, and demographic distribution of Enterovirus D68.

Worldwide outbreaks of enterovirus D68 (EV-D68) in 2014 and 2016 have caused serious respiratory and neurological disease. We collected samples from several European countries during the 2018 outbreak and determined 53 near full-length genome ('whole genome') sequences. These sequences were combined with 718 whole genome and 1,987 VP1-gene publicly available sequences. In 2018, circulating strains clustered into multiple subgroups in the B3 and A2 subclades, with different phylogenetic origins. Clusters in subclade B3 emerged from strains circulating primarily in the US and Europe in 2016, though some had deeper roots linking to Asian strains, while clusters in A2 traced back to strains detected in East Asia in 2015-2016. In 2018, all sequences from the USA formed a distinct subgroup, containing only three non-US samples. Alongside the varied origins of seasonal strains, we found that diversification of these variants begins up to 18 months prior to the first diagnostic detection during a EV-D68 season. EV-D68 displays strong signs of continuous antigenic evolution and all 2018 A2 strains had novel patterns in the putative neutralizing epitopes in the BC- and DE-loops. The pattern in the BC-loop of the USA B3 subgroup had not been detected on that continent before. Patients with EV-D68 in subclade A2 were significantly older than patients with a B3 subclade virus. In contrast to other subclades, the age distribution of A2 is distinctly bimodal and was found primarily among children and in the elderly. We hypothesize that EV-D68's rapid evolution of surface proteins, extensive diversity, and high rate of geographic mixing could be explained by substantial reinfection of adults. Better understanding of evolution and immunity across diverse viral pathogens, including EV-D68 and SARS-CoV-2, is critical to pandemic preparedness in the future

Estudio de cohortes en atención primaria sobre la evolución de sujetos con prediabetes (PREDAPS). Fundamentos y metodología

El estudio PREDAPS pretende determinar el riesgo de desarrollo de diabetes y aparición de complicaciones vasculares en sujetos con prediabetes e identificar los factores asociados. Se trata de un estudio observacional de seguimiento de una cohorte de 1.184 sujetos con prediabetes y otra cohorte de 838 sujetos sin alteraciones en el metabolismo de la glucosa. Los datos de la etapa basal se obtuvieron de pacientes que acudieron a centros de Atención Primaria en España a lo largo del año 2012. Los sujetos con prediabetes fueron clasificados en tres grupos: aquellos que sólo tenían alteradas las cifras de glucemia en ayunas -entre 100 y 125 mg/dl-, aquellos que sólo tenían alterado el nivel de HbA1c -entre 5,7 y 6,4%- y aquellos que tenían alterados ambos parámetros. La información sobre sus características sociodemográficas, antecedentes familiares y personales, estilos de vida y tratamiento farmacológico se obtuvo de la historia clínica y de la entrevista realizada en la consulta por el médico. Se realizó un examen físico para determinar peso, talla, perímetro de la cintura y presión arterial y se realizaron análisis de sangre y orina. El estudio PREDAPS puede contribuir a disminuir la incertidumbre en las estrategias individuales de prevención en los sujetos con prediabetes. El seguimiento anual durante cinco años de los participantes posibilitará conocer el riesgo de desarrollo de diabetes mellitus tipo 2 y el de complicaciones macro y microvasculares en los tres grupos de sujetos con prediabetes, así como averiguar los posibles factores asociados a esos riesgos. The PREDAPS study aims to determine the risk of developing diabetes and the risk of vascular complications in patients with prediabetes and identify factors associated with those risks. It is a prospective observational study of a cohort of 1184 subjects with prediabetes and another cohort of 838 subjects with no alterations in glucose metabolism. The data at baseline were obtained from patients attending primary care centers in Spain throughout 2012. Subjects with prediabetes were classified into three groups: those who had only altered the fasting blood glucose levels -between 100 and 125mg/dl-, those who had only altered the HbA1c level -between 5.7 and 6.4% - and those who had altered both parameters. Information on sociodemographic characteristics, personal and family history, lifestyle and drug therapy was obtained from medical records and the interview with the doctor in the consultation. It was also performed a physical examination to determine weight, height, waist circumference and blood pressure were performed and blood and urine analysis. The PREDAPS study may help to reduce uncertainty in individual prevention strategies in subjects with prediabetes. Annual monitoring of patients recruited for five years will enable to know the risk of developing diabetes type 2 and the risk of macro-and microvascular complications in the three groups of subjects with prediabetes and determine the factors associated with those risks

Modifiable risk factors associated with prediabetes in men and women: A cross-sectional analysis of the cohort study in primary health care on the evolution of patients with prediabetes

Background: Prediabetes is a high-risk state for diabetes development, but little is known about the factors associated with this state. The aim of the study was to identify modifiable risk factors associated with the presence of prediabetes in men and women. Methods: Cohort Study in Primary Health Care on the Evolution of Patients with Prediabetes (PREDAPS-Study) is a prospective study on a cohort of 1184 subjects with prediabetes and another cohort of 838 subjects without glucose metabolism disorders. It is being conducted by 125 general practitioners in Spain. Data for this analysis were collected during the baseline stage in 2012. The modifiable risk factors included were: smoking habit, alcohol consumption, low physical activity, inadequate diet, hypertension, dyslipidemia, and obesity. To assess independent association between each factor and prediabetes, odds ratios (ORs) were estimated using logistic regression models. Results: Abdominal obesity, low plasma levels of high-density lipoprotein cholesterol (HDL-cholesterol), and hypertension were independently associated with the presence of prediabetes in both men and women. After adjusting for all factors, the respective ORs (95% Confidence Intervals) were 1.98 (1.41-2.79), 1.88 (1.23-2.88) and 1.86 (1.39-2.51) for men, and 1.89 (1.36-2.62), 1.58 (1.12-2.23) and 1.44 (1.07-1.92) for women. Also, general obesity was a risk factor in both sexes but did not reach statistical significance among men, after adjusting for all factors. Risky alcohol consumption was a risk factor for prediabetes in men, OR 1.49 (1.00-2.24). Conclusions: Obesity, low HDL-cholesterol levels, and hypertension were modifiable risk factors independently related to the presence of prediabetes in both sexes. The magnitudes of the associations were stronger for men than women. Abdominal obesity in both men and women displayed the strongest association with prediabetes. The findings suggest that there are some differences between men and women, which should be taken into account when implementing specific recommendations to prevent or delay the onset of diabetes in adult population

Chemotherapy or allogeneic transplantation in high-risk Philadelphia chromosome–negative adult lymphoblastic leukemia

The need for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adults with Philadelphia chromosome–negative (Ph−) acute lymphoblastic leukemia (ALL) with high-risk (HR) features and adequate measurable residual disease (MRD) clearance remains unclear. The aim of the ALL-HR-11 trial was to evaluate the outcomes of HR Ph− adult ALL patients following chemotherapy or allo-HSCT administered based on end-induction and consolidation MRD levels. Patients aged 15 to 60 years with HR-ALL in complete response (CR) and MRD levels (centrally assessed by 8-color flow cytometry) <0.1% after induction and <0.01% after early consolidation were assigned to receive delayed consolidation and maintenance therapy up to 2 years in CR. The remaining patients were allocated to allo-HSCT. CR was attained in 315/348 patients (91%), with MRD <0.1% after induction in 220/289 patients (76%). By intention-to-treat, 218 patients were assigned to chemotherapy and 106 to allo-HSCT. The 5-year (±95% confidence interval) cumulative incidence of relapse (CIR), overall survival (OS), and event-free survival probabilities for the whole series were 43% ± 7%, 49% ± 7%, and 40% ± 6%, respectively, with CIR and OS rates of 45% ± 8% and 59% ± 9% for patients assigned to chemotherapy and of 40% ± 12% and 38% ± 11% for those assigned to allo-HSCT, respectively. Our results show that avoiding allo-HSCT does not hamper the outcomes of HR Ph− adult ALL patients up to 60 years with adequate MRD response after induction and consolidation. Better postremission alternative therapies are especially needed for patients with poor MRD clearance
