Características del uso de tratamiento alternativo y complementario en dismenorrea en mujeres en edad fértil

Objetive: To describe the characteristics of the use of alternative and complementary treatment in dysmenorrhea in women of childbearing age in a city in northern Peru. The study: Cross-sectional analytical study in women of childbearing age in Mórrope, Lambayeque. Prior training on dysmenorrhea and main variables. 336 women were interviewed in their homes after accepting informed consent. Findings: The age group of 15 to 35 years prevailed in the studied population with 83.92% (n=282), with secondary education 57.14% (n=192), more than 90% had lower/marginal socioeconomic status. Regarding dysmenorrhea, more than 30% were found to have severe/unbearable pain, whose main treatment was MAC with 82.1% (n=220). Plants were the main MAC, only finding an association of MAC use with the religion variable (p=0.023). Conclusions: Women of childbearing age notoriously use CAM, such as phytotherapy, as a treatment for dysmenorrhea despite not finding reliefObjetivo: Describir las características del uso de tratamiento alternativo y complementario en dismenorrea en mujeres en edad fértil de una ciudad del norte de Perú. El estudio: Estudio trasversal analítico en mujeres en edad fértil en Mórrope, Lambayeque. Previa capacitación sobre dismenorrea y principales variables. Se entrevistó a 336 mujeres en sus domicilios previa aceptación de consentimiento informado. Hallazgos: Predominó en población estudiada el grupo etario de 15 a 35 años con 83,92% (n=282), con educación secundaria el 57,14% (n=192), más del 90% tenían estrato socioeconómico inferior/marginal. Referente a la dismenorrea, se encontró más del 30% con dolor severo/insoportable, cuyo tratamiento principal fue la MAC con 82,1%(n=220). Las plantas fueron la principal MAC, hallando solamente asociación de uso de MAC con la variable religión (p=0,023). Conclusiones: Las mujeres en edad fértil emplean notoriamente la MAC, como la fitoterapia, como tratamiento de dismenorrea a pesar de no encuentran alivio

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

The global impact of the COVID-19 pandemic on the management and course of chronic urticaria

Introduction: The COVID-19 pandemic dramatically disrupts health care around the globe. The impact of the pandemic on chronic urticaria (CU) and its management are largely unknown. Aim: To understand how CU patients are affected by the COVID-19 pandemic; how specialists alter CU patient management; and the course of CU in patients with COVID-19. Materials and Methods: Our cross-sectional, international, questionnaire-based, multicenter UCARE COVID-CU study assessed the impact of the pandemic on patient consultations, remote treatment, changes in medications, and clinical consequences. Results: The COVID-19 pandemic severely impairs CU patient care, with less than 50% of the weekly numbers of patients treated as compared to before the pandemic. Reduced patient referrals and clinic hours were the major reasons. Almost half of responding UCARE physicians were involved in COVID-19 patient care, which negatively impacted on the care of urticaria patients. The rate of face-to-face consultations decreased by 62%, from 90% to less than half, whereas the rate of remote consultations increased by more than 600%, from one in 10 to more than two thirds. Cyclosporine and systemic corticosteroids, but not antihistamines or omalizumab, are used less during the pandemic. CU does not affect the course of COVID-19, but COVID-19 results in CU exacerbation in one of three patients, with higher rates in patients with severe COVID-19. Conclusions: The COVID-19 pandemic brings major changes and challenges for CU patients and their physicians. The long-term consequences of these changes, especially the increased use of remote consultations, require careful evaluation

Search for intermediate-mass black hole binaries in the third observing run of Advanced LIGO and Advanced Virgo

International audienceIntermediate-mass black holes (IMBHs) span the approximate mass range 100−105 M⊙, between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of galaxies. Mergers of IMBH binaries are the most energetic gravitational-wave sources accessible by the terrestrial detector network. Searches of the first two observing runs of Advanced LIGO and Advanced Virgo did not yield any significant IMBH binary signals. In the third observing run (O3), the increased network sensitivity enabled the detection of GW190521, a signal consistent with a binary merger of mass ∼150 M⊙ providing direct evidence of IMBH formation. Here, we report on a dedicated search of O3 data for further IMBH binary mergers, combining both modeled (matched filter) and model-independent search methods. We find some marginal candidates, but none are sufficiently significant to indicate detection of further IMBH mergers. We quantify the sensitivity of the individual search methods and of the combined search using a suite of IMBH binary signals obtained via numerical relativity, including the effects of spins misaligned with the binary orbital axis, and present the resulting upper limits on astrophysical merger rates. Our most stringent limit is for equal mass and aligned spin BH binary of total mass 200 M⊙ and effective aligned spin 0.8 at 0.056 Gpc−3 yr−1 (90% confidence), a factor of 3.5 more constraining than previous LIGO-Virgo limits. We also update the estimated rate of mergers similar to GW190521 to 0.08 Gpc−3 yr−1.Key words: gravitational waves / stars: black holes / black hole physicsCorresponding author: W.
