Emotions and decision rightness over five years following an abortion: An examination of decision difficulty and abortion stigma

Available online 13 January 2020, Article 112704Uno de los estudios más grandes sobre las emociones de las mujeres después de un aborto encontró que la mayoría se siente aliviada y no se arrepiente de su elección, incluso si pensaron mucho para tomar la decisión o si se preocuparon por el estigma. Los investigadores descubrieron que a los cinco años de haber tenido un aborto, solo el 6% expresó principalmente emociones negativas. La abrumadora mayoría de las mujeres encuestadas, el 84%, tenían emociones positivas o ninguna con respecto a su decisión de abortar, incluso si no se habían sentido así cuando estaban tomando la decisión de abortar.Poco más de la mitad de las mujeres en esta encuesta dijeron que la decisión de interrumpir el embarazo fue muy difícil y el 27% lo calificó como “algo difícil”. Alrededor del 46% dijo que no fue una decisión difícil en absoluto. Casi el 70% dijo sentir que serían estigmatizadas si las personas supieran que tuvieron un aborto. Las mujeres que dijeron que fue difícil tomar la decisión o se sintieron estigmatizadas por ella tenían más probabilidades de reportar culpa, ira o tristeza inmediatamente después del aborto, pero con el tiempo, estos sentimientos disminuyeron drásticamente, a veces incluso un año después del aborto.La principal emoción que todos los grupos de mujeres en el estudio dijeron que sintieron al final de la encuesta fue el alivio. El alivio era una emoción utilizada para describir cómo se sentían cada vez que se les preguntaba al respecto.www.elsevier.com/locate/socscime

Morbidity and nutrition status of rural drug-naïve Kenyan women living with HIV

This paper describes morbidity in a group of HIV-positive drug-naïve rural women in western Kenya. A total of 226 drug-naïve HIV-positive women were evaluated for baseline morbidity, immune function, and anthropometry before a food-based nutrition intervention. Kenyan nurses visited women in their homes and conducted semi-structured interviews regarding symptoms and physical signs experienced at the time of the visit and during the previous week and physical inspection. Blood and urine samples were examined for determination of immune function (CD4, CD8, and total lymphocyte counts), anaemia, malaria, and pregnancy status. Intradermal skin testing with tuberculin (PPD), candida, and tetanus toxoid antigens was also performed to evaluate cell-mediated immunity. Anthropometry was measured, and body mass index (BMI) was calculated. Seventy-six per cent of the women reported being sick on the day of the interview or within the previous week. Illnesses considered serious were reported by 13.7% of women. The most frequent morbidity episodes reported were upper respiratory tract infections (13.3%), suspected malaria (5.85%), skeletal pain (4.87%), and stomach pain (4.42%). The most common morbidity signs on physical inspection were respiratory symptoms, most commonly rhinorrhea and coughing. Confirmed malaria and severe diarrhea were significantly associated with a higher BMI

Reproductive justice in the time of COVID-19: a systematic review of the indirect impacts of COVID-19 on sexual and reproductive health

Objective Despite gendered dimensions of COVID-19 becoming increasingly apparent, the impact of COVID-19 and other respiratory epidemics on women and girls’ sexual and reproductive health (SRH) have yet to be synthesized. This review uses a reproductive justice framework to systematically review empirical evidence of the indirect impacts of respiratory epidemics on SRH. Methods We searched MEDLINE and CINAHL for original, peer-reviewed articles related to respiratory epidemics and women and girls’ SRH through May 31, 2021. Studies focusing on various SRH outcomes were included, however those exclusively examining pregnancy, perinatal-related outcomes, and gender-based violence were excluded due to previously published systematic reviews on these topics. The review consisted of title and abstract screening, full-text screening, and data abstraction. Results Twenty-four studies met all eligibility criteria. These studies emphasized that COVID-19 resulted in service disruptions that effected access to abortion, contraceptives, HIV/STI testing, and changes in sexual behaviors, menstruation, and pregnancy intentions. Conclusions These findings highlight the need to enact policies that ensure equitable, timely access to quality SRH services for women and girls, despite quarantine and distancing policies. Research gaps include understanding how COVID-19 disruptions in SRH service provision, access and/or utilization have impacted underserved populations and those with intersectional identities, who faced SRH inequities notwithstanding an epidemic. More robust research is also needed to understand the indirect impact of COVID-19 and epidemic control measures on a wider range of SRH outcomes (e.g., menstrual disorders, fertility services, gynecologic oncology) in the long-term

The Association of AMPK with ULK1 Regulates Autophagy

Autophagy is a highly orchestrated intracellular bulk degradation process that is activated by various environmental stresses. The serine/threonine kinase ULK1, like its yeast homologue Atg1, is a key initiator of autophagy that is negatively regulated by the mTOR kinase. However, the molecular mechanism that controls the inhibitory effect of mTOR on ULK1-mediated autophagy is not fully understood. Here we identified AMPK, a central energy sensor, as a new ULK1-binding partner. We found that AMPK binds to the PS domain of ULK1 and this interaction is required for ULK1-mediated autophagy. Interestingly, activation of AMPK by AICAR induces 14-3-3 binding to the AMPK-ULK1-mTORC1 complex, which coincides with raptor Ser792 phosphorylation and mTOR inactivation. Consistently, AICAR induces autophagy in TSC2-deficient cells expressing wild-type raptor but not the mutant raptor that lacks the AMPK phosphorylation sites (Ser722 and Ser792). Taken together, these results suggest that AMPK association with ULK1 plays an important role in autophagy induction, at least in part, by phosphorylation of raptor to lift the inhibitory effect of mTOR on the ULK1 autophagic complex

Cells and gene expression programs in the adult human heart

Cardiovascular disease is the leading cause of death worldwide. Advanced insights into disease mechanisms and strategies to improve therapeutic opportunities require deeper understanding of the molecular processes of the normal heart. Knowledge of the full repertoire of cardiac cells and their gene expression profiles is a fundamental first step in this endeavor. Here, using large-scale single cell and nuclei transcriptomic profiling together with state-of-the-art analytical techniques, we characterise the adult human heart cellular landscape covering six anatomical cardiac regions (left and right atria and ventricles, apex and interventricular septum). Our results highlight the cellular heterogeneity of cardiomyocytes, pericytes and fibroblasts, revealing distinct subsets in the atria and ventricles indicative of diverse developmental origins and specialized properties. Further we define the complexity of the cardiac vascular network which includes clusters of arterial, capillary, venous, lymphatic endothelial cells and an atrial-enriched population. By comparing cardiac cells to skeletal muscle and kidney, we identify cardiac tissue resident macrophage subsets with transcriptional signatures indicative of both inflammatory and reparative phenotypes. Further, inference of cell-cell interactions highlight a macrophage-fibroblast-cardiomyocyte network that differs between atria and ventricles, and compared to skeletal muscle. We expect this reference human cardiac cell atlas to advance mechanistic studies of heart homeostasis and disease

Cells of the adult human heart

Abstract: Cardiovascular disease is the leading cause of death worldwide. Advanced insights into disease mechanisms and therapeutic strategies require a deeper understanding of the molecular processes involved in the healthy heart. Knowledge of the full repertoire of cardiac cells and their gene expression profiles is a fundamental first step in this endeavour. Here, using state-of-the-art analyses of large-scale single-cell and single-nucleus transcriptomes, we characterize six anatomical adult heart regions. Our results highlight the cellular heterogeneity of cardiomyocytes, pericytes and fibroblasts, and reveal distinct atrial and ventricular subsets of cells with diverse developmental origins and specialized properties. We define the complexity of the cardiac vasculature and its changes along the arterio-venous axis. In the immune compartment, we identify cardiac-resident macrophages with inflammatory and protective transcriptional signatures. Furthermore, analyses of cell-to-cell interactions highlight different networks of macrophages, fibroblasts and cardiomyocytes between atria and ventricles that are distinct from those of skeletal muscle. Our human cardiac cell atlas improves our understanding of the human heart and provides a valuable reference for future studies
