Interleukin-10 Gene Polymorphisms Modulate the Risk of Infertility in Chlamydia trachomatis Positive Kurdish Women in Erbil Province.

Background: There is evident inter-individual variability in women's responses to Chlamydial infections and reproductive tract problems. Women's genetic variations within the Interleukin-10 (IL-10) gene have been linked to variances in response to Chlamydia trachomatis infection. This study was aimed to demonstrate the profound association of IL-10 with infertility and demonstrate the role of IL-10 (-592 C/A rs1800872) and (-1082 A>G rs1800896) single nucleotide polymorphism (SNPs) gene in the susceptibility and severity of a C. trachomatis infection. Methods: In this evaluation study, serum IL-10 concentration was measured in 134 women diagnosed with infertility and 50 healthy volunteers by enzyme-linked immunosorbent assay (ELISA). The tetra-amplification refractory mutation system-PCR (T-ARMS-PCR) analysis was performed to detect the genotyping of the rs1800872 and rs1800896 SNPs genes. Results: Both female groups were positive for anti-chlamydial IgM antibody, but the intensity of response differed between cases. At the same time, the incidence of genital C. trachomatis by PCR was 46.2% in infertile women. The serum concentration of IL10 was lower in infertile women than healthy participants and higher in infertile C. trachomatis -positive women compared to infertile C. trachomatis-negative in all groups except endometriosis (Endo) infertility. In rs1800872, the CA genotype and C allele are associated with an increased risk for infertility, except in polycystic ovarian syndrome (PCOS), which is an A allele. In the case of rs1800896, the AG genotype and G allele show a greater risk for infertility. Conclusions: Our results confirmed that rs1800872 and rs1800896 gene polymorphisms were associated with an increased risk of C. trachomatis infection.

Sperm performance in the race for fertilization, the influence of female reproductive fluid.

In studies of sperm competition, particularly in external fertilizers, the importance of the fertilization environment on the paternity share among rival males often goes overlooked. The female reproductive fluid (FRF), produced and released by females, creates the microenvironment that sperm encounter on their quest for fertilization and can generate paternity biases by affecting key traits in sperm competition. Yet, whether there is a direct link between FRF effects on sperm traits and its effect on competitive fertilization dynamics remains to be explored. Here, using the zebrafish Danio rerio, we compare within-female paternity share among two competing males and predictors of fertilization success (i.e. sperm traits) in the presence/absence of FRF. Our results unequivocally reveal a direct link between the direction and magnitude of the effect of FRF on sperm traits and the change in the competitive fertilization success of each male. This study demonstrates that the FRF directly mediates post-mating female control through its differential effect on sperm performance and that the FRF's effect on sperm quality alone is sufficient to predict the magnitude of the fitness effects. These findings highlight the need to consider the role of FRF in fertilization, avoiding biases resulting from an exclusive focus on male intrinsic sperm quality.

Asprosin-induced alterations in female rat puberty and reproductive hormonal profiles.

OBJECTIVE: To investigate the comprehensive effects of daily chronic asprosin administration on various pubertal and reproductive parameters in female rats. This study aims to elucidate the role of asprosin in regulating the onset of puberty and its influence on hormonal profiles and ovarian histology. METHODS: Asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg daily for eight weeks. Hormonal assays and histological analyses were performed to evaluate the effects of asprosin on the onset of puberty and reproductive function. RESULTS: Daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays revealed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. CONCLUSIONS: Role of adipokines in regulating puberty and reproductive function has increasingly gained recognition. This study aimed to provide the first comprehensive examination of the effects of daily chronic asprosin administration on pubertal and reproductive parameters in female rats. Utilising hormonal assays and histological analyses, asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg, daily, for eight weeks. Our findings revealed that daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays showed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. These results provide new insights into asprosin's role in advancing the age of first oestrus and modulating hormonal profiles, thereby offering potential benefits to the female reproductive system.

A health decision analytical model to evaluate the cost-effectiveness of female genital schistosomiasis screening strategies: The female genital schistosomiasis SCREEN framework.

Female genital schistosomiasis is a chronic gynaecological disease caused by the waterborne parasite Schistosoma (S.) haematobium. It affects an estimated 30-56 million girls and women globally, mostly in sub-Saharan Africa where it is endemic, and negatively impacts their sexual and reproductive life. Recent studies found evidence of an association between female genital schistosomiasis and increased prevalence of HIV and cervical precancer lesions. Despite the large population at risk, the burden and impact of female genital schistosomiasis are scarcely documented, resulting in neglect and insufficient resource allocation. There is currently no standardised method for individual or population-based female genital schistosomiasis screening and diagnosis which hinders accurate assessment of disease burden in endemic countries. To optimise financial allocations for female genital schistosomiasis screening, it is necessary to explore the cost-effectiveness of different strategies by combining cost and impact estimates. Yet, no economic evaluation has explored the value for money of alternative screening methods. This paper describes a novel application of health decision analytical modelling to evaluate the cost-effectiveness of different female genital schistosomiasis screening strategies across endemic settings. The model combines a decision tree for female genital schistosomiasis screening strategies, and a Markov model for the natural history of cervical cancer to estimate the cost per disability-adjusted life-years averted for different screening strategies, stratified by HIV status. It is a starting point for discussion and for supporting priority setting in a data-sparse environment.

Sestrin2 knockout exacerbates high-fat diet induced metabolic disorders and complications in female mice.

BACKGROUND: Obesity and its associated complications raise significant public concern, revealing gender disparities in the susceptibility to metabolic disorders, with females often displaying greater resistance to obesity-related metabolic disorder than males. Sestrin2 is a crucial protein involved in metabolism and energy balance. This study seeks to explore whether Sesn2 knockout (KO) exacerbates high-fat diet (HFD) induced obesity in female mice. METHODS: Female mice with wild-type (WT) and Sesn2 KO were subjected to a 12-week regimen of normal diet or HFD. Using a Body Composition Analyzer, body composition was gauged. Biochemical assays encompassed glucose, lipid, and liver function measurements, alongside 24-hour urine albumin excretion. Echocardiographic evaluation assessed cardiac function. Histopathological analysis of key metabolic tissues (liver, kidney, and heart tissues) were conducted. Western blotting or qRT-PCR evaluated key proteins and genes linked to inflammation, mitochondrial, and lipid metabolism in adipose tissues. RESULTS: In comparison to mice fed a regular diet, those on a HFD exhibited significant increases in body weight and fat mass. Notably, Sesn2 KO further aggravated obesity, showcasing the most pronounced metabolic anomalies: elevated body weight, fat mass, impaired glucose tolerance, and insulin sensitivity, alongside heightened levels of free fatty acids and triglycerides. Additionally, KO-HFD mice displayed exacerbated multi-tissue impairments, including elevated hepatic enzymes, increased urinary albumin excretion, compromised cardiac function, and accumulation of lipids in the liver, kidney, and heart. Moreover, adipose tissue showcased altered lipid dynamics and function, characterized by enhanced triglyceride breakdown and modified adipokine levels. Browning was diminished, along with decreased Pgc1α and Sirt1 in KO-HFD mice. CONCLUSION: Sesn2 KO exacerbates HFD-induced obesity and metabolic disorders in female mice. These findings underscore Sestrin2's novel role as a regulator of obesity in female mice.

Microglial heterogeneity in the ischemic stroke mouse brain of both sexes.

BACKGROUND: Ischemic stroke elicits a complex and sustained immune response in the brain. Immunomodulatory treatments have long held promise for improving stroke outcomes, yet none have succeeded in the clinical setting. This lack of success is largely due to our incomplete understanding of how immune cells respond to stroke. The objective of the current study was to dissect the effect of permanent stroke on microglia, the resident immune cells within the brain parenchyma. METHODS: A permanent middle cerebral artery occlusion (pMCAO) model was used to induce ischemic stroke in young male and female mice. Microglia were sorted from fluorescence reporter mice after pMCAO or sham surgery and then subjected to single-cell RNA sequencing analysis. Various methods, including flow cytometry, RNA in situ hybridization, immunohistochemistry, whole-brain imaging, and bone marrow transplantation, were also employed to dissect the microglial response to stroke. Stroke outcomes were evaluated by infarct size and behavioral tests. RESULTS: First, we showed the morphologic and spatial changes in microglia after stroke. We then performed single-cell RNA sequencing analysis on microglia isolated from sham and stroke mice of both sexes. The data indicate no major sexual dimorphism in the microglial response to permanent stroke. Notably, we identified seven potential stroke-associated microglial clusters, including four major clusters characterized by a disease-associated microglia-like signature, a highly proliferative state, a macrophage-like profile, and an interferon (IFN) response signature, respectively. Importantly, we provided evidence that the macrophage-like cluster may represent the long-sought stroke-induced microglia subpopulation with increased CD45 expression. Lastly, given that the IFN-responsive subset constitutes the most prominent microglial population in the stroke brain, we used fludarabine to pharmacologically target STAT1 signaling and found that fludarabine treatment improved long-term stroke outcome. CONCLUSIONS: Our findings shed new light on microglia heterogeneity in stroke pathology and underscore the potential of targeting specific microglial populations for effective stroke therapies.

Hyperglycemia sensitizes female mice to stress-induced depressive-like behavior in an inflammation-independent manner.

BACKGROUND: Depression is a multifaceted disorder that represents one of the most common causes of disability. The risk for developing depression is increased in women and among individuals with chronic diseases. For example, individuals in the United States with diabetes mellitus (DM) are at a twofold increased risk of developing depression compared to the general population and approximately one-quarter of women with diabetes have comorbid depression. The neurobiological mechanisms underlying this association between diabetes and depression is not fully understood and is particularly under-investigated in female models. We sought to explore the role of neuroinflammation in diabetes-induced depression in a female mouse model of hyperglycemia. METHODS: To this end, we utilized female C57BL/6 J mice to (1) characterize the depressive-like symptoms in response to 75 mg/kg/day dose of streptozotocin (STZ) over 5 days, a dose reported to induce hyperglycemia in female mice (n=20), (2) determine if female hyperglycemic mice are sensitized to unpredictable chronic mild stress (UCMS)-induced depressive-like behavior and neuroinflammation (n=28), and (3) investigate if female hyperglycemic mice are primed to respond to a subthreshold dose of lipopolysaccharide (LPS), an acute inflammatory challenge (n=21). RESULTS: Our results demonstrate that female mice exhibit robust hyperglycemia but limited evidence of depressive-like behavior in response to 75 mg/kg STZ. Additionally, we observe that healthy female mice have limited response to our stress protocol; however, hyperglycemic mice display increased stress-sensitivity as indicated by increased immobility in the forced swim test. While STZ mice show evidence of mild neuroinflammation, this effect was blunted by stress. Further, STZ mice failed to display a sensitization to inflammation-induced depressive-like behavior. CONCLUSION: We interpret this data to indicate that while STZ-induced hyperglycemia does increase vulnerability to stress-induced depressive-like behavior, this effect is not a consequence of neuroinflammatory priming. Future studies will seek to better understand the mechanisms underlying this sensitization.

Female sexual dysfunction and distress in premenopausal women with migraine followed in a tertiary headache center: A pilot study.

BACKGROUND: Female sexual dysfunction (FSD) is an underdiagnosed and undertreated problem. Few studies have addressed sexual distress in migraine. We aimed to perform a pilot study to determine if there is an association between migraine and sexual dysfunction/distress in premenopausal women and to identify their respective risk factors. METHODS: Retrospective, cross-sectional pilot study, including 71 premenopausal female patients with migraine, from the headache outpatient clinic of a tertiary hospital, and 34 age-matched-controls. Female Sexual Function Index-6 (FSFI-6), Female Sexual Distress Scale-Revised (FSDS-R), Migraine Disability Assessment (MIDAS) Scale, Brief Pain Inventory (BPI), Hospital Anxiety and Depression Scale (HADS) and Sleep Health Scale (RU-SATED) were applied. RESULTS: Of the 71 patients [40.0 (IQR = 11.00) years], only 12.7 % (n = 9) were not under migraine prophylactic treatment, and most (n = 33, 62.3 %) reported severe disability (MIDAS-IV). FSD and sexual distress were present in 50.7 % (36) patients with migraine [vs 20.6 % (7) controls]. Migraine patients showed lower FSFI-6 scores [19.0 (9.0) vs 24.0 (6.0), p = 0.005], with significantly lower levels of desire (p = 0.011), lubrication (p = 0.002), and satisfaction (p = 0.013), higher sexual distress [11.2 (25.6) vs 3.2 (9.6), p = 0.001], anxiety (p < 0.001), and depression (p < 0.001) levels, and lower sleep health scores (p = 0.005). Old age of onset, being under preventive medication, anxiety/depression, and dysfunctional sleep, were significantly associated with sexual distress. Certain domains of sexual function were associated with sociodemographic and migraine characteristics, anxiety, depression, and sleep health. CONCLUSIONS: This pilot study highlights the possible association between migraine and elevated sexual dysfunction/distress levels among premenopausal women. It underscores the importance of sexual health assessments in these individuals, particularly those with higher levels of anxiety, depression, or poor sleep quality. It is important to exercise caution when interpreting results, as they may not be applicable to a wider context. This research paves the way for a larger study that will include a broader population of women from the community and encompass patients followed in different levels of health care.

Exposure to Childhood Adversity and Intimate Partner Violence in a Sample of Incarcerated Women in Australia.

Women who use violence represent one of the fastest growing groups within the Australian prisoner population, including Aboriginal women who are more likely to be incarcerated than non-Aboriginal women for violent crimes. Many incarcerated women report histories of adverse childhood experiences (ACEs) and intimate partner violence. This exploratory study examines baseline data from a sample of 167 women in 3 Western Australia women's prisons enrolled in a gender-specific violent behavior program. It describes their exposure to intimate partner violence, head injury, and childhood adversities. Overall, 94% of women had experienced at least one childhood adversity (median 6), and 94% reported being a victim of physical violence by a current or former intimate partner. Aboriginal women were more likely than non-Aboriginal women to report that a family member was incarcerated as a child (p = .001). There was an association between an increased number of ACEs and head injury with a loss of consciousness (p = .008). Overall, these results present a harrowing picture of childhood exposure to adversity and violence in adulthood. Successful rehabilitation of women incarcerated for violent crimes should be cognizant of the histories of extreme violence endured by most of these women.

Current investigation of the high prevalence of sexual dysfunction in female patients with systemic lupus erythematosus: a cross-sectional study.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects women of childbearing age and has been reported to cause sexual dysfunction in women. Although there are articles on sexual function in women with SLE, the number of articles is small, and the factors affecting sexual function in women with SLE are controversial. Based on this, this study aimed to investigate the prevalence of sexual dysfunction in Chinese female SLE patients and to explore the factors that influence it. The study design was a cross-sectional study conducted from December 2023 to April 2024 in the Department of Rheumatology and Immunology of a tertiary hospital in Hefei, Anhui Province. A total of 293 female patients diagnosed with SLE were enrolled using face-to-face questionnaires and online questionnaires. The questionnaire consisted of four parts: general information questionnaire, fatigue severity scale (FSS), depression-anxiety-stress scale (DASS-21), and female sexual functioning index (FSFI) scale. A total of 173 (59.04%) patients had sexual dysfunction, including 251 (85.67%) with decreased libido and 186 (63.46%) with difficulty in sexual arousal. There was a correlation between the patients' total FSFI scores and age (p = 0.028), marital satisfaction (p < 0.001), own education level (p = 0.008), partner's education level (p = 0.003), place of residence (p = 0.039), monthly household income (p < 0.001), family financial satisfaction(p < 0.001), menstrual status (p = 0.003), hormone use (p = 0.021),immunosuppressant use (p = 0.042), disease activity (p = 0.016), FSS score (p < 0.001), stress score (p < 0.001), anxiety score (p < 0.001) and depression score (p < 0.001)were correlated. The results of stepwise regression analysis showed that marital satisfaction (b = 2.011, t = 3.797, p < 0.001), monthly household income (b = 0.854, t = 2.316, p = 0.021), menstrual status (b = 1.218, t = 2.350, p = 0.019), fatigue scale score (b = - 0.069, t = - 2.302, p = 0.022), and depression score (b = - 0.117, t = - 2.910, p = 0.004) were the influencing factors of FSFI total score, and the difference was statistically significant. The incidence of sexual dysfunction in Chinese female SLE patients is high, and medical personnel should pay more attention to patients' sexual problems, to provide theoretical and practical bases for further prevention, treatment, and care of sexual dysfunction in female SLE patients.

Ankle, knee and concussion concerns: Unveiling injury patterns in highly trained South African netball players.

OBJECTIVES: To describe the rate and type of netball injuries sustained during women's university-level tournament matches in South Africa. DESIGN: Descriptive epidemiological study. SETTING: Three editions of the women's Varsity Netball tournament (2021-23). PARTICIPANTS: Student-athletes representing nine university women's teams. MAIN OUTCOME MEASURES: Medical attention match injuries prospectively recorded by team medical staff. Injuries were classified according to the 2020 consensus statement, with the addition of "concussion" as a separate pathology type. The main outcomes are reported as incidence (injuries per 1000h; 95% confidence intervals - CIs), burden (days lost per 1000h; 95%CIs), and frequency (% of all injuries). RESULTS: Sixty-three injuries were recorded from 48 different players (58.8 per 1000h; 45.2-75.3) and the overall injury burden was 401 days per 1000h (364-440). Injury incidence by pathology type was highest for joint sprains (28.9 per 1000h), tendinopathies (7.5 per 1000h), and concussions (4.7 per 1000h). Joint sprains to the ankle accounted for 49% of the overall estimated days lost. CONCLUSIONS: Ankle joint sprains should be the primary target of injury risk reduction programmes in highly trained netball players. Concussions were reported and efforts should be made to increase awareness among players, coaches and medical staff.

Psychosocial and Sexual Aspects of Female Genital Circumcision in a Sample of Kurdish Women in the Kurdistan Region of Iraq.

BACKGROUND AND AIM: Female genital circumcision (FGC), a prevalent practice in the Kurdistan Region of Iraq, has significant psychosocial and sexual implications for affected women. Therefore, this study aimed to investigate these impacts among circumcised and non-circumcised Kurdish women. METHOD: This comparative study was conducted from January 2 to June 27, 2023, at the Al Mesalla for Human Rights Improvement organization in Erbil, Iraq. Purposive sampling was used to collect data using a comprehensive questionnaire. The questionnaire included demographic information, the Depression, Anxiety, and Stress Scale (DASS-21), the Rosenberg Self-Esteem Scale (RSE), and the New Sexual Satisfaction Scale-Short Form (NSSS-S). Statistical analysis was performed using SPSS version 26 (IBM Corp., Armonk, NY), with frequency and percentage used for categorical variables and mean and standard deviation for quantitative variables. Independent sample t-tests and Chi-square tests were conducted to compare groups. A p-value of less than 0.05 was considered statistically significant. RESULTS: A total of 772 participants were enrolled in the study, including 382 circumcised and 390 non-circumcised women. The study found significant differences between the two groups in terms of depression, self-esteem, and sexual satisfaction. Circumcised women had higher mean scores for depression (12.19 ± 5.6 vs. 10.68 ± 5.3), lower mean scores for self-esteem (24.4 ± 12.1 vs. 30.3 ± 10.1), and lower mean scores for sexual satisfaction (52.4 ± 24.6 vs. 67.6 ± 20.4) compared to non-circumcised women (all p < 0.001). CONCLUSIONS: The study demonstrated that FGC is associated with higher levels of depression, lower self-esteem, and lower sexual satisfaction among Kurdish women. It is recommended for policymakers and healthcare providers to develop targeted interventions to address the psychosocial and sexual health needs of circumcised women in the Kurdistan Region of Iraq.

Hormonal Contraceptive Influence on Baseline Vestibular/Ocular Symptomatology and Provocation for Concussion.

Background: Hormonal contraceptives (HCs) and the menstrual cycle have been suggested to affect symptom severity and postconcussion recovery. Additionally, hormones have been a suggested rationale for sex differences between female and male athletes on concussion assessment. Researchers have yet to explore the effects of HC use on baseline symptomatology, including symptom reporting and provocation. Purpose: To examine the influence of HC use on a baseline symptom reporting and vestibular/ocular provocation battery. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 61 college-aged individuals (21 HC-using women, 21 non-HC-using women, 19 men) were administered a baseline symptom battery consisting of the Post-Concussion Symptom Scale (PCSS), Headache Impact Test-6 (HIT-6), Pediatric Vestibular Symptom Questionnaire (PVSQ), and Vestibular/Ocular Motor Screening (VOMS). The main outcome measures consisted of PCSS symptom reporting (total symptoms, symptom severity score, and symptom factors), HIT-6 and PVSQ total scores, and VOMS item (ie, saccades, convergence, or vestibular/ocular reflex) symptom provocation scores. Results: Significant differences were reported on HIT-6, with the highest headache reporting in the HC group (P = .026). On the PVSQ, the HC group also reported greater dizziness and unsteadiness symptoms than the non-HC group (P = .023). Similar findings existed on the PCSS, with the HC group reporting greater total symptoms (P < .001), symptom severity (P < .001), and vestibular-somatic (P = .024), cognitive-sensory (P = .004), sleep-arousal (P = .001), and affective (P < .001) factors compared with the non-HC group. Smooth pursuit (ie, following finger smoothly with eyes) was the only VOMS items with differences between groups (P = .003), with the HC group having greater provocation compared with non-HC users (P = .020). Conclusion: HC use was associated with overall symptomatology and worse self-reported symptoms on vestibular-related inventories and concussion symptom scales and factors when compared with non-HC users and male controls. Additionally, HC users reported higher VOMS provocation scores on the smooth pursuit item than non-HC users and male controls.

SIK2 and SIK3 differentially regulate mouse granulosa cell response to exogenous gonadotropins in vivo.

Salt-inducible kinases (SIKs), a family of serine/threonine kinases, were found to be critical determinants of female fertility. SIK2 silencing results in increased ovulatory response to gonadotropins. In contrast, SIK3 knockout results in infertility, gonadotropin insensitivity, and ovaries devoid of antral and preovulatory follicles. This study hypothesizes that SIK2 and SIK3 differentially regulate follicle growth and fertility via contrasting actions in the granulosa cells (GCs), the somatic cells of the follicle. Therefore, SIK2 or SIK3 GC-specific knockdown (SIK2GCKD and SIK3GCKD, respectively) mice were generated by crossing SIK floxed mice with Cyp19a1pII-Cre mice. Fertility studies revealed that pup accumulation over six months and the average litter size of SIK2GCKD mice are similar to controls, though SIK3GCKD mice are significantly lower compared to controls. Compared to controls, gonadotropin stimulation of prepubertal SIK2GCKD mice results in significantly higher serum estradiol levels, whereas SIK3GCKD mice produced significantly less estradiol. Cyp11a1, Cyp19a1, and StAR were significantly increased in the GCs of gonadotropin-stimulated SIK2GCKD mice. However, Cyp11a1 and StAR remained significantly lower than controls in SIK3GCKD mice. Interestingly, Cyp19a1 stimulation in SIK3GCKD was not statistically different compared to controls. Superovulation resulted in SIK2GCKD mice ovulating significantly more oocytes, whereas SIK3GCKD mice ovulated significantly fewer oocytes than controls. Remarkably, SIK3GCKD superovulated ovaries contained significantly more preantral follicles than controls. SIK3GCKD ovaries contained significantly more apoptotic cells and fewer proliferating cells than controls. This data points to the differential regulation of GC function and follicle development by SIK2 and SIK3 and supports the therapeutic potential of targeting these kinases for treating infertility or developing new contraceptives.

Innervated breast reconstruction: a narrative review of neurotization techniques and outcomes.

Background and Objective: While significant sensation recovery improvements in neurotized breasts following reconstruction have been reported, sensation testing methods and surgical techniques have been widely variable. This narrative review aims to summarize available literature on current neurotization practices and sensory recovery outcomes in patients undergoing innervated breast reconstruction. Methods: A comprehensive literature search of PubMed Medline, Web of Science, and Embase was conducted to identify all studies reporting outcomes of neurotization in breast reconstruction surgeries. Data analyzed included operative times, neurotization techniques, sensory outcomes, and methods as well as patient reported outcomes. Key Content and Findings: Despite the heterogeneity of various studies reviewed, all forms of neurotization achieved earlier and superior sensory recovery throughout the reconstructed breast skin compared to non-innervated breasts. In absence of randomized controlled trials or high-quality comparative studies, further evidence is required to objectively confirm this technique offers better sensory recovery. Conclusions: Neurotization at the time of breast reconstruction may lead to improved sensation and patient reported outcomes delineating improved quality of life compared to non-innervated breasts. Future studies need to standardize the way that breast sensation is measured and determine pre-operative variables leading to expected changes in final sensation recovery to help manage surgical outcome expectations of both the surgeon and the patient.

Gender-specific prognosis models reveal differences in subarachnoid hemorrhage patients between sexes.

BACKGROUND: Subarachnoid hemorrhage (SAH) represents a severe stroke subtype. Our study aims to develop gender-specific prognostic prediction models derived from distinct prognostic factors observed among different-gender patients. METHODS: Inclusion comprised SAH-diagnosed patients from January 2014 to March 2016 in our institution. Collected data encompassed patients' demographics, admission severity, treatments, imaging findings, and complications. Three-month post-discharge prognoses were obtained via follow-ups. Analyses assessed gender-based differences in patient information. Key factors underwent subgroup analysis, followed by univariate and multivariate analyses to identify gender-specific prognostic factors and establish/validate gender-specific prognostic models. RESULTS: A total of 929 patients, with a median age of 57 (16) years, were analyzed; 372 (40%) were male, and 557 (60%) were female. Differences in age, smoking history, hypertension, aneurysm presence, and treatment interventions existed between genders (p < 0.01), yet no disparity in prognosis was noted. Subgroup analysis explored hypertension history, aneurysm presence, and treatment impact, revealing gender-specific variations in these factors' influence on the disease. Screening identified independent prognostic factors: age, SEBES score, admission GCS score, and complications for males; and age, admission GCS score, intraventricular hemorrhage, treatment interventions, symptomatic vasospasm, hydrocephalus, delayed cerebral ischemia, and seizures for females. Evaluation and validation of gender-specific models yielded an AUC of 0.916 (95% CI: 0.878-0.954) for males and 0.914 (95% CI: 0.885-0.944) for females in the ROC curve. Gender-specific prognostic models didn't significantly differ from the overall population-based model (model 3) but exhibited robust discriminative ability and clinical utility. CONCLUSION: Variations in baseline and treatment-related factors among genders contribute partly to gender-based prognosis differences. Independent prognostic factors vary by gender. Gender-specific prognostic models exhibit favorable prognostic performance.

The global burden, trends and cross-country inequalities of female breast and gynaecologic cancers: A population based study.

OBJECTIVE: To analyse the global burden, trends and cross-country inequalities of female breast and gynaecologic cancers (FeBGCs). DESIGN: Population-Based Study. SETTING: Data sourced from the Global Burden of Disease Study 2019. POPULATION: Individuals diagnosed with FeBGCs. METHODS: Age-standardised mortality rates (ASMRs), age-standardised Disability-Adjusted Life Years (DALYs) rates (ASDRs) and their 95% uncertainty interval (UI) described the burden. Estimated annual percentage changes (EAPCs) and their confidence interval (CI) of age-standardised rates (ASRs) illustrated trends. Social inequalities were quantified using the Slope Index of Inequality (SII) and Concentration Index. MAIN OUTCOME MEASURES: The main outcome measures were the burden of FeBGCs and the trends in its inequalities over time. RESULTS: In 2019, the ASDRs per 100 000 females were as follows: breast cancer: 473.83 (95% UI: 437.30-510.51), cervical cancer: 210.64 (95% UI: 177.67-234.85), ovarian cancer: 124.68 (95% UI: 109.13-138.67) and uterine cancer: 210.64 (95% UI: 177.67-234.85). The trends per year from 1990 to 2019 were expressed as EAPCs of ASDRs and these: for Breast cancer: -0.51 (95% CI: -0.57 to -0.45); Cervical cancer: -0.95 (95% CI: -0.99 to -0.89); Ovarian cancer: -0.08 (95% CI: -0.12 to -0.04); and Uterine cancer: -0.84 (95% CI: -0.93 to -0.75). In the Social Inequalities Analysis (1990-2019) the SII changed from 689.26 to 607.08 for Breast, from -226.66 to -239.92 for cervical, from 222.45 to 228.83 for ovarian and from 74.61 to 103.58 for uterine cancer. The concentration index values ranged from 0.2 to 0.4. CONCLUSIONS: The burden of FeBGCs worldwide showed a downward trend from 1990 to 2019. Countries or regions with higher Socio-demographic Index (SDI) bear a higher DALYs burden of breast, ovarian and uterine cancers, while those with lower SDI bear a heavier burden of cervical cancer. These inequalities increased over time.

Acute and long COVID-19 symptoms and associated factors in the omicron-dominant period: a nationwide survey via the online platform Wenjuanxing in China.

BACKGROUNDS: To our knowledge, there is no available nationwide data on omicron symptom patterns in China mainland. We aim to determine the acute and long COVID-19 symptoms in the omicron-dominant period and to evaluate its association with risk factors. METHODS: We designed a cross-sectional nationwide study and data about self-reported symptoms were collected by an online platform named Wenjuanxing. Eligible participants were aged 25-65 years and were symptomatic. In this study, the ratios of the number of people of different ages and genders were weighted by the data from the Seventh National Census (2020 years), and validated by a published nationwide representative study through comparing smoking rates. Descriptive indicators were calculated for demographic characteristics, diagnosis ways, and duration time, acute symptoms, hospitalization, severity and long COVID-19 symptoms. And, the associations between risk factors and acute and long COVID-19 symptoms were analyzed by multivariable logistic regression models. RESULTS: A total of 32,528 individuals diagnosed as COVID-19 infection from October 1, 2022 to February 21, 2023 were included. The first three acute symptoms of COVID-19 infection were fever (69.90%), headache (62.63%), and sore throat (54.29%), respectively. The hospitalization rate within 7 days was 3.07% and symptoms disappearance rate within 21 days was 68.84%, respectively. Among 3983 COVID-19 patients with 3 months or more time difference between first infection and participation into the study, the long COVID-19 rate was 19.68% and the primary symptoms were muscle weakness (19.39%), headache (17.98%) and smell/taste disorder (15.18%). Age groups, smoking, marriage status and vaccination were risk factors for numbers of acute phase symptoms and long COVID-19 symptoms. Lastly, female and current smokers also showed more numbers of symptoms during acute infection period. CONCLUSIONS: In Chinese mainland, our respondent indicated that current smokers and women were associated with acute COVID-19 symptoms, which should be treated with caution due to the lack of representative.

Transcriptional profiling of mucus production in rhesus macaque endocervical cells under hormonal regulation.

OBJECTIVE: Endocervical mucus production is a key regulator of fertility throughout the menstrual cycle. With cycle-dependent variability in mucus quality and quantity, cervical mucus can either facilitate or block sperm ascension into the upper female reproductive tract. This study seeks to identify genes involved in the hormonal regulation of mucus production, modification, and regulation through profiling the transcriptome of endocervical cells from the non-human primate, the rhesus macaque (Macaca mulatta). INTERVENTION: We treated differentiated primary endocervical cultures with estradiol (E2) and progesterone (P4) to mimic peri-ovulatory and luteal-phase hormonal changes. Using RNA-sequencing, we identified differential expression of gene pathways and mucus producing and modifying genes in cells treated with E2 compared to hormone-free conditions and E2 compared to E2-primed cells treated with P4. MAIN OUTCOME MEASURES: We pursued differential gene expression analysis on RNA-sequenced cells. Sequence validation was done using qPCR. RESULTS: Our study identified 158 genes that show significant differential expression in E2-only conditions compared to hormone-free control, and 250 genes that show significant differential expression in P4-treated conditions compared to E2-only conditions. From this list, we found hormone-induced changes in transcriptional profiles for genes across several classes of mucus production, including ion channels and enzymes involved in post-translational mucin modification that have not previously been described as hormonally regulated. CONCLUSION: Our study is the first to use an in vitro culture system to create an epithelial-cell specific transcriptome of the endocervix. As a result, our study identifies new genes and pathways altered by sex-steroids in cervical mucus production.

Cervical cancer screening practice and associated factors among female health care professionals in Ethiopia 2024: a systematic review and meta-analysis.

BACKGROUND: Cervical cancer, ranking as the fourth most common gynecological cancer worldwide, claimed an estimated 570,000 lives and resulted in 311,000 new cases in 2018. This disease disproportionately affects those living in poverty and is more prevalent in countries with weak healthcare systems. Low and middle-income nations, particularly in Sub-Saharan Africa, face higher incidence and mortality rates due to limited access to vaccines, screening, and treatment. The world health organization recommends regular screening for women from age 25, setting a 90-70-90 target for low- and middle-income countries by 2030. Despite limited previous knowledge, the study aims to assess the pooled prevalence of cervical cancer screening practices and associated factors among female healthcare professionals in Ethiopia in 2024. OBJECTIVE: The study aimed to synthesize the existing literature on cervical cancer screening practice and associated factors among female health workers in Ethiopia. METHODS: Studies were searched through the search engine of Google Scholar, PubMed, and Cochrane Library. Searching was made using Keywords/ MeSH terms Cervical cancer; utilization; Preventive practice. Heterogeneity was assessed using the Cochran Q test and I2 statistics. A random-effects model with a 95% confidence interval was used for the pooled prevalence and odds ratio estimations. RESULT: Seven studies were included in this systematic review and meta-analysis. The overall pooled prevalence of cervical cancer screening practice among female health workers in Ethiopia was 18%. Work place(OR = 2.858;95% CI: 0.412, 5.305),knowledge(OR = 3.457; 95% CI: 2.314, 4.601), work experience(OR = 5.421; 95% CI:4.178,6.664),being diagnosed(OR = 10.787; 95% CI: 06.197,15.377) and ever cared of cervical cancer patient (OR = 2.93; 95% CI: 2.004, 3.856) were the pooled associated factors that are significantly associated with cervical cancer screening practice among female health care worker. CONCLUSION: The implementation of preventive measures for cervical cancer screening was found to be suboptimal. Our findings underscore the importance of enhancing awareness among this demographic, which is crucial in mobilizing local communities. It is imperative to provide continuous education to female health workers regarding cervical cancer. The Ministry of Health should collaborate with various organizations to ensure the accessibility of cost-effective screening services in all healthcare facilities.
