UNASSIGNED: Intimate partner violence (IPV) is a major public health problem in Latin America. The present study investigates the protective factors that contribute to minimizing the risk of exposure to IPV analyzing different variables in a sample of Chilean women victims of IPV.
UNASSIGNED: We used data from the Cicatrices Foundation, a nonprofit Chilean organization providing psychological support to IPV victims. Relevant variables for IPV prevention were identified analyzing a database containing all the information reported by victims during a structured interview. A final sample of 444 women suffering IPV was used in the present study.
UNASSIGNED: Logistic regression analysis was calculated in order to make predictions related to IPV protective factors, showing that having a support network (OR = 2.85), treatment compliance (OR = 2.05) and being younger (OR = 0.95) increased the probability of not living with the aggressor. Another logistic regression analysis was calculated in order to predict IPV victims´ health taking medication intake as an indicator. A significant association was observed between this variable and working outside (p = 0.002) and between mediation intake and age (p < 0.001), with an OR of 1.987 and 0.93, respectively. Working outside and being younger were identified as protective factors against consuming medication.
UNASSIGNED: To the best of our knowledge, this is one of the first studies conducted in Chile on the prevention of IPV in a sample of victims seeking for help. Our results will contribute to guide policy makers, researchers and other women in the prevention of potential risks for IPV.

UNASSIGNED: Peri-postmenopausal women with the chronic condition polycystic ovary syndrome (PCOS) remain at cardiometabolic risk and/or subsist with established comorbidity while continuing to manage persistent PCOS signs and symptoms, such as hirsutism. Thus, PCOS transcends the reproductive years, yet there is sparse scientific literature on the peri-postmenopausal years of women with PCOS.
UNASSIGNED: To explore how peri-postmenopausal women\'s perceptions about PCOS have changed over the lifespan since their PCOS diagnosis.
UNASSIGNED: A cross-sectional survey with one qualitative question was conducted via Research Electronic Data Capture (REDCap) among women with PCOS aged ≥43 years, who were all recruited from PCOS-specific Facebook pages. Of the 107 women completing the survey, 72 substantively answered the qualitative question. The qualitative responses were analyzed using the steps of reflexive thematic analysis. Themes were interpreted and discussed through the lens of the bioecological conceptual model.
UNASSIGNED: Respondents were 47.6 (±4.1) years of age, primarily White (87.5%), employed full time (65.3%), and married (75%) with children (68%). Four overall themes were identified: 1) dismissal 2) information desert, 3) PCOS experience over the lifespan, and 4) mindset.
UNASSIGNED: The study findings illustrated the unique healthcare needs among peri-postmenopausal women with PCOS. Further research is needed to further explore their healthcare concerns and psychosocial needs followed by studies that develop and assess interventions that promote symptom and adaptive coping strategies across their lifespan.

OBJECTIVE: To assess the effectiveness of the Cultural, Social and Emotional Wellbeing Program for reducing psychological distress and enhancing the social and emotional wellbeing of Aboriginal women preparing for release from prison.
METHODS: Mixed methods; qualitative study (adapted reflexive thematic analysis of stories of most significant change) and assessment of psychological distress.
METHODS: Aboriginal and Torres Strait Islander women at the Boronia Pre-release Centre for Women, Perth, Western Australia, May and July 2021.
METHODS: Cultural, Social and Emotional Wellbeing Program (two days per week for six weeks). The Program involves presentations, workshops, activities, group discussions, and self-reflections designed to enhance social and emotional wellbeing.
METHODS: Themes and subthemes identified from reflexive thematic analysis of participants\' stories of most significant change; change in mean psychological distress, as assessed with the 5-item Kessler Scale (K-5) before and after the Program.
RESULTS: Fourteen of 16 invited women completed the Program; ten participated in its evaluation. They reported improved social and emotional wellbeing, reflected as enhanced connections to culture, family, and community. Mean psychological distress was lower after the Program (mean K-5 score, 11.3; 95% confidence interval [CI], 9.0-13.6) than before the Program (9.0; 95% CI, 6.5-11.5; P = 0.047).
CONCLUSIONS: The women who participated in the Program reported personal growth, including acceptance of self and acceptance and pride in culture, reflecting enhanced social and emotional wellbeing through connections to culture and kinship. Our preliminary findings suggest that the Program could improve the resilience of Aboriginal and Torres Strait Islander in contact with the justice system.

OBJECTIVE: Although parity, infertility, and age at first birth are important for later development of cardiovascular disease, research on their association with atrial fibrillation (AF) is limited.
METHODS: We linked data from the population-based HUNT study, the Medical Birth Registry of Norway (MBRN) and validated medical records from local hospitals. A total of 24,015 women aged 45 years or older were followed for verified incident AF. Parity and age at first birth were retrieved from the MBRN or from self-reported questionnaires in the HUNT. History of infertility was self-reported on the HUNT questionnaire. Cox-proportional hazard models were used to calculate hazard ratios (HR) for the multivariable-adjusted associations of parity, infertility, and age at first birth with risk of AF.
RESULTS: During a median follow-up of 12.8 years, 1,448 (6.0%) participants developed AF. Women with higher parity (four or more births vs. two births) were at 21% higher risk of AF (HR 1.21, 95% confidence interval (CI), 1.05-1.39). History of infertility was also associated with risk of AF (HR 1.20, 95% CI, 1.02-1.42). Among parous women, younger age at first birth (<20 years vs. 20-29 years) was associated with a 20% higher risk of AF (HR 1.20, 95% CI, 1.03-1.40).
CONCLUSIONS: Women with four or more births, or a history of infertility, or younger age at first birth have approximately a 20% higher risk of AF among women over 45 years old.
A higher number of births and younger age at first birth are associated with a higher risk of cardiovascular disease (CVD). However, there is limited evidence on the associations between parity, age at first birth and atrial fibrillation (AF). Moreover, the association between infertility and AF remains largely unexplored. We have investigated the association between parity, infertility, age at first birth and AF in the population-based cohort from Norway (the HUNT study) among women over 45 years old. Our findings reveal that women with four or more births, or a history of infertility, or younger age at first birth have approximately a 20% higher risk of AF.

BACKGROUND: Breastfeeding benefits both the mother and infant and is a topic of attention in public health. After childbirth, untreated medical conditions or lack of support lead many mothers to discontinue breastfeeding. For instance, nipple damage and mastitis affect 80% and 20% of US mothers, respectively. Lactation consultants (LCs) help mothers with breastfeeding, providing in-person, remote, and hybrid lactation support. LCs guide, encourage, and find ways for mothers to have a better experience breastfeeding. Current telehealth services help mothers seek LCs for breastfeeding support, where images help them identify and address many issues. Due to the disproportional ratio of LCs and mothers in need, these professionals are often overloaded and burned out.
OBJECTIVE: This study aims to investigate the effectiveness of 5 distinct convolutional neural networks in detecting healthy lactating breasts and 6 breastfeeding-related issues by only using red, green, and blue images. Our goal was to assess the applicability of this algorithm as an auxiliary resource for LCs to identify painful breast conditions quickly, better manage their patients through triage, respond promptly to patient needs, and enhance the overall experience and care for breastfeeding mothers.
METHODS: We evaluated the potential for 5 classification models to detect breastfeeding-related conditions using 1078 breast and nipple images gathered from web-based and physical educational resources. We used the convolutional neural networks Resnet50, Visual Geometry Group model with 16 layers (VGG16), InceptionV3, EfficientNetV2, and DenseNet169 to classify the images across 7 classes: healthy, abscess, mastitis, nipple blebs, dermatosis, engorgement, and nipple damage by improper feeding or misuse of breast pumps. We also evaluated the models\' ability to distinguish between healthy and unhealthy images. We present an analysis of the classification challenges, identifying image traits that may confound the detection model.
RESULTS: The best model achieves an average area under the receiver operating characteristic curve of 0.93 for all conditions after data augmentation for multiclass classification. For binary classification, we achieved, with the best model, an average area under the curve of 0.96 for all conditions after data augmentation. Several factors contributed to the misclassification of images, including similar visual features in the conditions that precede other conditions (such as the mastitis spectrum disorder), partially covered breasts or nipples, and images depicting multiple conditions in the same breast.
CONCLUSIONS: This vision-based automated detection technique offers an opportunity to enhance postpartum care for mothers and can potentially help alleviate the workload of LCs by expediting decision-making processes.

BACKGROUND: Early age at menarche (AAM) is a risk factor for type 2 diabetes later in life, but the pathogenic pathways that confer increased risk remain unknown.
OBJECTIVE: We examined the associations between AAM and inflammatory and glucose metabolism biomarkers among U.S. adult women who were free of diabetes.
METHODS: Using the National Health and Nutrition Examination Survey (NHANES) 1999-2018, 19,228 women over 20 years old who were free of self-reported cancer and diabetes were included in this cross-sectional analysis. AAM was the self-reported age at first menstruation. CRP, fasting glucose, fasting insulin, and ferritin levels were measured as biomarkers of inflammation and glucose metabolism in adult blood samples using latex-enhanced nephelometry, enzymatic, and immunoassay methods. Multiple linear regression was used to relate AAM to the biomarkers.
RESULTS: The median age at the time of blood sample collection was 44 years (IQR, 33-62). After age adjustment, there was an association between a lower AAM and higher CRP (P-trend=0.006); fasting glucose (P-trend<0.0001); fasting insulin (P-trend <0.0001); and ferritin (p-trend<0.0001). These remained significant after additional adjustment for demographic, reproductive, lifestyle, and adiposity variables, except for ferritin. Smoking modified the effect of AAM on CRP (p-interaction = 0.014), fasting insulin (p-interaction <0.001), and fasting glucose (p-interaction<0.001). In stratified analysis, the observed associations became more pronounced in non-smokers, while they were attenuated to non-significance in active smokers.
CONCLUSIONS: Earlier age at menarche is associated with an unfavorable inflammatory and glucose metabolic biomarker profile in a nationally representative sample of adult women free of diabetes, especially among non-smokers.

UNASSIGNED: We assessed the in vitro anti-chlamydial activity of fresh vaginal secretions, deciphering the microbial and metabolic components able to counteract Chlamydia trachomatis viability.
UNASSIGNED: Forty vaginal samples were collected from a group of reproductive-aged women and their anti-chlamydial activity was evaluated by inhibition experiments. Each sample underwent 16S rRNA metabarcoding sequencing to determine the bacterial composition, as well as 1H-NMR spectroscopy to detect and quantify the presence of vaginal metabolites.
UNASSIGNED: Samples characterized by a high anti-chlamydial activity were enriched in Lactobacillus, especially Lactobacillus crispatus and Lactobacillus iners, while not-active samples exhibited a significant reduction of lactobacilli, along with higher relative abundances of Streptococcus and Olegusella. Lactobacillus gasseri showed an opposite behavior compared to L. crispatus, being more prevalent in not-active vaginal samples. Higher concentrations of several amino acids (i.e., isoleucine, leucine, and aspartate; positively correlated to the abundance of L. crispatus and L. jensenii) lactate, and 4-aminobutyrate were the most significant metabolic fingerprints of highly active samples. Acetate and formate concentrations, on the other hand, were related to the abundances of a group of anaerobic opportunistic bacteria (including Prevotella, Dialister, Olegusella, Peptostreptococcus, Peptoniphilus, Finegoldia and Anaerococcus). Finally, glucose, correlated to Streptococcus, Lachnospira and Alloscardovia genera, emerged as a key molecule of the vaginal environment: indeed, the anti-chlamydial effect of vaginal fluids decreased as glucose concentrations increased.
UNASSIGNED: These findings could pave the way for novel strategies in the prevention and treatment of chlamydial urogenital infections, such as lactobacilli probiotic formulations or lactobacilli-derived postbiotics.

UNASSIGNED: The purpose of this scoping review is to explore research studies on the association between chronic pain and polycystic ovary syndrome to create local (U.S.-based) and global recommendations to improve access to and quality of affordable symptom management and treatment options for patients with polycystic ovary syndrome.
UNASSIGNED: The study sections used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews as a checklist reference. The review followed the York methodology by Arksey and O\'Malley for the extraction, analysis, and presentation of results in scoping reviews.
UNASSIGNED: Final analysis included two conference abstracts published in peer-reviewed journals and two peer-reviewed articles. The relationship between pain perception and health-related quality of life warrants further investigation in patients with polycystic ovary syndrome as the interconnected pathophysiology of symptoms renders exploring associations between the two factors difficult. A comprehensive understanding of the causes of polycystic ovary syndrome-associated symptoms, particularly those relating to pain perceptions can provide more insight into polycystic ovary syndrome pathophysiology and aid in the development of innovative therapeutic approaches for long-term polycystic ovary syndrome management and care.
UNASSIGNED: Future studies are necessary to examine associations between the disease and pathophysiological symptoms for a better quality of life for patients with polycystic ovary syndrome.

OBJECTIVE: This study aims to estimate the prevalence of individuals receiving hormone therapy for menopause management and the prevalence of underlying conditions that may constrain options for pharmacologic menopause management in the prison context.
METHODS: This study reviewed all prescriptions dispensed by the North Carolina Department of Public Safety between July 1, 2015, and June 30, 2016, for relevance to menopause management. Relevant medications were those either recommended for menopause management or those indicated for management of conditions that may complicate menopause management, as per the 2015 clinical decision-support algorithm tool developed by the North American Menopause Society. Analysis was restricted to women between the ages of 45 and 75.
RESULTS: Of 1,120 women, a majority (77.8%) were between the ages of 45 and 54. Less than 5% of individuals in this study were prescribed estrogen-containing therapy. The most commonly prescribed medications that may constrain options for menopause treatment were related to hypertension and other cardiovascular disease or mental health conditions.
CONCLUSIONS: The retrospective nature of this data set limits the findings, given that researchers did not have access to diagnoses or data on polypharmacy. Still, this study indicates that many women over 45 experiencing incarceration are living with health conditions that may complicate menopause symptom management with hormone therapy. Future research in carceral settings must examine the prevalence of menopause-related symptoms as well as access to and quality of comprehensive menopause management.
CONCLUSIONS: There is a paucity of literature around the menopause-related needs of individuals experiencing incarceration. To the best of the authors\' knowledge, no other research has examined prevalence of pharmacologic menopause management among women who are incarcerated.
