Assessment of the fat mass index in women recently diagnosed with gynecological tumors / Evaluación del índice de masa grasa en mujeres diagnosticadas recientemente de tumores ginecológicos

Objectives: to evaluate the nutritional status and body composition of women with gynecological tumors and evaluate the fat mass index (FMI) as a complementary indicator for addressing the nutrition status. Methods: a cross-sectional study with women recently diagnosed with gynecological tumors. Nutritional status was assessed using conventional anthropometry and the Patient-Generated Subjective Global Assessment. For body composition, bioelectrical impedance was used. Results: a total of 158 women participated, most of them with excess weight and high body fat. The FMI showed a positive and significant correlation with body mass index, arm circumference, tricipital skinfold, and arm muscle circumference. Conclusion: women recently diagnosed with gynecological tumors had excess weight and high body fat. The FMI may be a potentially useful indicator to complement the assessment of nutritional status and help the multidisciplinary team to perform early clinical and nutritional interventions (AU)

Objetivos: evaluar el estado Nutricional y la composición corporal de mujeres con tumores ginecológicos, y evaluar el índice de masa grasa (IMG) como indicador Nutricional complementario. Métodos: estudio transversal con mujeres diagnosticadas recientemente de tumores ginecológicos. El estado Nutricional se evaluó mediante la antropometría convencional y la Evaluación Global Subjetiva Generada por el Paciente. Para la composición corporal se utilizó la impedancia bioeléctrica. Resultados: participaron 158 mujeres, la mayoría con exceso de peso y grasa corporal alta. El IMG mostró una correlación positiva y significativa con el índice de masa corporal, la circunferencia del brazo, el pliegue cutáneo tricipital y la circunferencia de los músculos del brazo. Conclusión: las mujeres diagnosticadas recientemente con tumores ginecológicos presentaron exceso de peso y grasa corporal alta. El IMG puede ser un indicador potencialmente útil para complementar la evaluación del estado Nutricional y ayudar al equipo multidisciplinario a realizar intervenciones clínicas y Nutricionales tempranas (AU)

Livestock-associated methicillin-resistant Staphylococcus aureus (clonal complex 398) causing bacteremia and epidural abscess.

Methicillin-resistant Staphylococcus aureus (MRSA) clonal complex (CC) 398 has spread from pigs to humans, but rarely from person to person. This strain of MRSA has been considered less virulent than others. Livestock-associated MRSA CC398 (LA-MRSA CC398) is particularly known to colonize pig farmers. Recent studies have shown an increasing number of people colonized with LA-MRSA CC398 and invasive infections caused by LA-MRSA CC398. The case of a previously healthy, 61-year-old woman admitted to a Danish regional hospital is reported here. She presented with fever, severe back pain, and bilateral hyperreflexia of patellar and Achilles reflexes. Blood tests revealed leukocytosis and elevated C-reactive protein. Empiric antimicrobial therapy with intravenous piperacillin-tazobactam was initiated, but blood cultures grew MRSA and antimicrobial therapy was changed to intravenous vancomycin. Whole-genome sequencing showed that the MRSA strain belonged to LA-MRSA CC398 spa type t011 and was Panton-Valentine leukocidin-negative. Magnetic resonance imaging revealed an epidural abscess at the level of L1-L4. Surgery was performed and pus from the abscess grew MRSA. The duration of antimicrobial therapy was 12 weeks. This case report describes bacteremia with LA-MRSA CC398 in a previously healthy patient without exposure to livestock or previous admission to a hospital. This highlights the risk of person-to-person transmission of LA-MRSA CC398 and brings into question whether LA-MRSA CC398 may have a greater pathogenic potential than previously assumed.

Determination of the separation efficiencies of a single-stage cryogenic distillation setup to remove krypton out of xenon by using a (83m)Kr tracer method.

The separation of krypton and xenon is of particular importance for the field of direct dark matter search with liquid xenon detectors. The intrinsic contamination of the xenon with radioactive (85)Kr makes a significant background for these kinds of low count-rate experiments and has to be removed beforehand. This can be achieved by cryogenic distillation, a technique widely used in industry, using the different vapor pressures of krypton and xenon. In this paper, we present an investigation on the separation performance of a single stage distillation system using a radioactive (83m)Kr-tracer method. The separation characteristics under different operation conditions are determined for very low concentrations of krypton in xenon at the level of (83m)Kr/Xe = 1.9 ⋅ 10(-15), demonstrating, that cryogenic distillation in this regime is working. The observed separation is in agreement with the expectation from the different volatilities of krypton and xenon. This cryogenic distillation station is the first step on the way to a multi-stage cryogenic distillation column for the next generation of direct dark matter experiment XENON1T.
