Animals exhibit sociability behaviors and spatial use patterns that are important for species survival. Bats are animals that exhibit complex patterns of aggregation of individuals, which can vary according to sex and age. Aggregation can be explained by active or passive mechanisms. In this behavioural note, we report a group of female Artibeus lituratus in the reproductive stage that exhibits aggregation behavior supporting the active mechanism hypothesis. The females returned to the same roost, for two reproductive season, maintaining the aggregation with the same individuals with which the social bonds were already established.

Os animais exibem comportamentos de sociabilidade e padrões de uso espacial que são importantes para a sobrevivência das espécies. Os morcegos são animais que apresentam padrões complexos de agregação de indivíduos, que podem variar de acordo com o sexo e a idade. A agregação pode ser explicada por mecanismos ativos ou passivos. Nesta nota comportamental, relatamos um grupo de fêmeas de Artibeus lituratus em fase reprodutiva que exibe comportamento de agregação apoiando a hipótese do mecanismo ativo. As fêmeas retornaram ao mesmo poleiro, por duas estações reprodutivas, mantendo a agregação com os mesmos indivíduos com os quais os laços sociais já foram estabelecidos.

Combination of low doses of mirtazapine plus venlafaxine produces antidepressant-like effects in rats, without affecting male or female sexual behavior.

RATIONALE: Pharmacological treatments for depression are not always effective and produce unwanted side effects. Male and female sexual dysfunction is one of these side effects, which can lead to treatment withdrawal. Combination of two antidepressants with different mechanisms of action, like mirtazapine (MTZ) and venlafaxine (VLF) have been shown to be effective for treatment-resistant depression in humans. Combination of low doses of these drugs may still exert antidepressant-like effects without altering sexual behavior. OBJECTIVES: To investigate the potential antidepressant-like effect of the chronic administration of low doses of MTZ plus VLF combined, as well as its impact on male and female sexual behavior in rats. METHODS: The antidepressant-like effect of a 14-day treatment with combinations of MTZ plus VLF (0/0, 2.5/3.75 or 5/7.5 mg/kg) was assessed in young adult male and female rats in the forced swim test (FST). The 5/7.5 mg/kg MTZ/VLF combination was also tested in the chronic mild stress (CMS) test, in both males and females treated for 21 days. The sexual effects of this last treatment were assessed in sexually experienced males and in gonadally-intact females during proestrus. RESULTS: The 5/7.5 mg/kg MTZ/VLF combination produced an antidepressant-like effect in the FST and reversed the CMS-induced anhedonia in both male and female rats. This combination did not alter male sexual behavior, female proceptive and receptive behaviors or the regularity of the estrous cycle. CONCLUSION: The combination of low doses of MTZ and VLF might be a promising therapeutic alternative to treat depression without affecting the sexual response.

Female Mice Exposed to Pyriproxyfen Since Prepuberty Showed Reproductive Impairment During Sexual Maturity and Increased Fetal Death in Their Offspring.

Pyriproxyfen (PPF) is an insecticide used in agriculture, which is approved for use in drinking water tanks for human consumption. However, some studies indicate that it may act as an endocrine disruptor and affect nontarget organisms. This study aimed to evaluate the effects of PPF on reproduction and general health status in female mice exposed from pre-puberty to adulthood. In the first experiment, females were treated by gavage from postnatal day (PND) 23 to (PND) 75 and were distributed into three experimental groups: control (vehicle), PPF 0.1 mg/kg, and PPF 1 mg/kg. Female mice were assessed for the age of puberty onset, body mass, water and food consumption, and the estrous cycle. On PDN 75, a subgroup was euthanized, when vital and reproductive organs were collected and weighed. The thyroid, ovary, and uterus were evaluated for histomorphometry. The other subgroup was assessed in relation to reproductive performance and fetal parameters. In a second experiment, the uterotrophic assay was performed with juvenile females (PND 18) using doses of 0.01, 0.1, or 1 mg/kg of PPF. PPF treatment reduced thyroid mass and increased liver mass. Furthermore, there was an increase in ovarian interstitial tissue and, in the uterus, a decrease in the thickness of the endometrial stroma with reduced content of collagen fibers. There was also a reduction of 30% in pregnancy rate in the treated groups and an increase in the frequency of fetal death. This study suggests that, based on this experimental model, the insecticide may pose a reproductive risk for females chronically exposed to the substance from the pre-pubertal period until adulthood. These results raise concerns about prolonged exposure of women to the same compound.

Heart Disease in Mothers of Children with Duchenne Muscular Dystrophy.

Female carriers of Duchenne Muscular Dystrophy (DMD) carry a heterozygous pathogenic variant in the dystrophin gene and can transmit pathogenic variants to their offspring. DMD is an X-linked recessive disease that affects up to 19.8 in every 100,000 male births. Those carriers with symptoms can be referred to as women with dystrophinopathy. Even among asymptomatic carriers, cardiac involvement can be verified in between 2.5% and 75% through echocardiography. The most commonly affected wall of the left ventricle is the inferolateral, with myocardial fibrosis detected by cardiac nuclear resonance. Therefore, screening is recommended for these women carriers due to the risk of cardiomyopathy. There is a lack of longitudinal studies on the evolution of these carriers. In this article, data on clinical presentation, cardiac assessment for female patients with dystrophinopathy and DMD carriers, and approaches for these patients are discussed.

Exposure to Treponema pallidum among Female Sex Workers: A Retrospective Study Conducted in the State of Pará, Brazilian Amazon.

BACKGROUND: Syphilis remains a significant global public health issue, and female sex workers (FSWs) are highly vulnerable to the etiological agent of this disease. This study aimed to describe the prevalence of exposure to Treponema pallidum, as well as the vulnerability factors among FSWs in the state of Pará, Brazilian Amazon. METHODS: A cross-sectional, retrospective study involving 360 FSWs from five cities in Pará was conducted from 2005 to 2007. Blood samples were collected for treponemal and non-treponemal testing, and epidemiological information was obtained through interviews. RESULTS: The exposure rate to T. pallidum was 37.7% (136/360), and the majority of FSWs had serological results indicating past exposure (21.1%). Among the FSWs exposed to T. pallidum, most of them were single, aged 23 to 42 years old, had less than 8 years of schooling, and had a family income of between 1 and 3 minimum wages. They reported using condoms during sexual intercourse and had no history of sexually transmitted infection (STI). Furthermore, many of the FSWs exposed to T. pallidum reported having more than 20 sexual partners per month, and had partners from other Brazilian states, but not from other countries. An age over 42 years and a reduced level of education were factors associated with exposure to T. pallidum. Finally, a high rate of exposure to T. pallidum among FSWs in the Brazilian state of Pará (from 2005 to 2007) was detected. In later years, epidemiological studies conducted with FSWs recorded that this rate remained high. Measures to control, treat, and prevent syphilis among FSWs were necessary between 2005 and 2007, and they are still imperative today. Actions related to educational programs and STI control, treatment, and prevention measures contained in Brazilian policies aimed at women's health have not changed the vulnerability scenario of FSWs regarding their exposure to T. pallidum, even after 16 years, and must be reviewed and adapted to the conditions of the Brazilian Amazon.

The modulatory role of serotonin-1A receptors of the basolateral amygdala and dorsal periaqueductal gray on the impact of hormonal variation on the conditioned fear response.

Despite significant advances in the study of fear and fear memory formation, little is known about fear learning and expression in females. This omission has been proven surprising, as normal and pathological behaviors are highly influenced by ovarian hormones, particularly estradiol and progesterone. In the current study, we investigated the joint influence of serotonin (5-HT) neurotransmission and estrous cycle phases (low or high levels of estradiol and progesterone) on the expression of conditioned fear in a group of female rats that were previously divided according to their response to stressful stimuli into low or high anxiety-like subjects. The baseline amplitude of the unconditioned acoustic startle responses was high in high-anxiety female rats, with no effect on the estrous cycle observed. Data collected during the proestrus-estrus phase revealed that low-anxiety rats had startle amplitudes similar to those of high-anxiety rats. It is supposed that high-anxiety female rats benefit from increased estradiol and progesterone levels to achieve comparable potentiated startle amplitudes. In contrast, female rats experienced a significant decrease in hormone levels during the Diestrus phase. This decrease is believed to play a role in preventing them from displaying a heightened startle response when faced with strongly aversive stimuli. Data collected after 5-HT and 8-OH-DPAT were administered into the basolateral nuclei and dorsal periaqueductal gray suggest that 5-HT neurotransmission works with progesterone and estrogen to reduce startle potentiation, most likely by activating the serotonin-1A receptor subtype.

Uterus transplantation: A scoping review focused on obstetric outcomes.

BACKGROUND: Congenital uterine anomalies include a wide diversity of uterine malformations that can compromise reproductive potential. Uterus transplantation (UTx) proposes an innovative treatment for absolute uterine factor infertility; however, there is a lack of standardized protocols to guide clinical management among this population. OBJECTIVES: To describe recipient and donor characteristics and obstetric outcomes in patients undergoing UTx. SEARCH STRATEGY: We performed a literature search using the PubMed database to retrieve available scientific articles. We analyzed the references of included articles to assess additional articles that could be eligible to be included in the review. Likewise, we identified further studies using other methods, including Google Scholar. SELECTION CRITERIA: Titles and abstracts were screened in duplicate to select original reports with information available for the outcomes of interest. DATA COLLECTION AND ANALYSIS: This review assessed the advantages and disadvantages of the techniques used, patient characteristics, obstetric and non-obstetric complications, functional duration of the organ, and neonatal outcomes. MAIN RESULTS: Among the 36 reports included in this review we found 55 pregnancies and 38 live births following UTx and a higher success rate for in vivo uterine donations. The most common obstetric complications reported included miscarriage, pre-eclampsia, and gestational hypertension. The most common non-obstetric complications reported include episodes of rejection, acute kidney injury, anemia, and cholestasis. Living donors required a comprehensive preoperative workup, decreasing organ rejection, infection, and vascular complications. CONCLUSIONS: More studies are needed to standardize the UTx procedure and improve obstetric, fetal, and neonatal outcomes. Further understanding of which recipient and donor characteristics minimize complications will significantly decrease the risk of adverse outcomes.

Split-scalp pilot study to evaluate effectiveness of Minoxidil 0,5% MMP® versus Topical Minoxidil 5% in the treatment of Female Pattern Hair Loss.

Female Pattern Hair Loss (FPHL) is a common form of non-scaring hair loss that occurs in adult women. Although several treatments have already been proposed for FPHL, only Topical Minoxidil accumulated an adequate level of evidence. This study aimed to evaluate the therapeutic response of MMP® (intradermal infiltration) of Minoxidil formulation in the frontal-parietal-vertex regions compared with the gold-standard home administration of Minoxidil 5% Capillary Solution. This self-controlled comparative study evaluated 16 FPHL patients, without treatment for at least 6 months, confirmed by trichoscopy with TrichoLAB® software. They received 4 monthly sessions of MMP® with Minoxidil 0,5% on the right side of the scalp (frontal-parietal-vertex areas), followed by occlusion with plastic film for 12 h and prescription of Minoxidil 5% Solution for home use once a day, on both scalp sides, starting 72 h after the procedure. The reassessment trichoscopy was 6 weeks after the last session and they answered a "self-assessment" questionnaire. Treated scalp areas were compared and showed both treatments, in general, were effective, with no difference between them. If they were analyzed separately by treated areas, there were signs of better response in the parietal-vertex regions with treatment by MMP® with Minoxidil, while clinical treatment indicated a better response in the other regions. When patients were divided into more and less advanced cases, a better response in parietal-vertex regions treated by MMP® with Minoxidil in less advanced patients was confirmed. MMP® with Minoxidil showed a better response in the parietal-vertex regions in less advanced FPHL patients. It represents yet another resource to improve quality of life of these suffering patients.

Hyaluronic acid to manage radiotoxicities in gynecological cancer patients: a scoping review.

PURPOSE: This study aimed to map the use of hyaluronic acid (HA) in preventing and controlling radiotoxicity in women with gynecological cancer undergoing radiotherapy. METHODS: We conducted a scoping review of eight electronic databases: CINAHL, Cochrane CENTRAL, LILACS, PubMed, Scopus, Embase, LIVIVO, and the Web of Science Core Collection. In addition, a grey literature search was performed using Google Scholar and ProQuest Dissertations & Theses Global. A manual search was also identified additional references. The search was conducted on May 18, 2023. We included primary studies, reviews, and guidelines that discussed the use of HA to prevent and manage the toxicities resulting from gynecological radiotherapy. RESULTS: Eighteen studies were included in this scoping review, published between 2009 and 2022. There was heterogeneity in the use of HA, particularly in the method of application (moisturizing gel, vaginal ovules, spacer gel, and bladder instillations). Furthermore, the radiotoxicities varied among studies, encompassing, among others, vaginal atrophy, dryness, dyspareunia, telangiectasis, adhesions, vaginal stenosis, bleeding, hematuria, and bladder issues. Most studies addressed the potential benefits of HA in managing the signs and symptoms resulting from radiotherapy. CONCLUSION: HA has been utilized in clinical practice, in various formulations, for managing signs and symptoms in patients with gynecological cancer undergoing radiotherapy. However, further studies are necessary to thoroughly investigate the most effective method of HA application and its effectiveness in managing radiotoxicity.

Genomic analysis of genotype-environment interaction in age at first calving of Murrah buffaloes.

Age at first calving (AFC) is a measure of sexual maturity associated with the start of productive life of dairy animals. Additionally, a lower AFC reduces the generation interval and early culling of females. However, AFC has low heritability, making it a trait highly influenced by environmental factors. In this scenario, one way to improve the reproductive performance of buffalo cows is to select robust animals according to estimated breeding value (EBV) using models that include genotype-environment interaction (GEI) with the application of reaction norm models (RNMs). This can be achieved by understanding the genomic basis related to GEI of AFC. Thus, in this study, we aimed to predict EBV considering GEI via the RNM and identify candidate genes related to this component in dairy buffaloes through genome-wide association studies (GWAS). We used 1795 AFC records from three Murrah buffalo herds and formed environmental gradients (EGs) from contemporary group solutions obtained from genetic analysis of 270-day cumulative milk yield. Heritability estimates ranged from 0.15 to 0.39 along the EG. GWAS of the RNM slope parameter identified important genomic regions. The genomic window that explained the highest percentage of genetic variance of the slope (0.67%) was located on BBU1. After functional analysis, five candidate genes were detected, involved in two biological processes. The results suggested the existence of a GEI for AFC in Murrah buffaloes, with reclassification of animals when different environmental conditions were considered. The inclusion of genomic information increased the accuracy of breeding values for the intercept and slope of the reaction norm. GWAS analysis suggested that important genes associated with the AFC reaction norm slope were possibly also involved in biological processes related to lipid metabolism and immunity.

Zoom & WhatsApp Digital Information and Communication Technologies (ICTs) Enhance Community Engaged Research with Women Immigrants from Mexico.

This article demonstrates how digital information and communication technologies (ICTs) (Zoom/WhatsApp) unexpectedly and counterintuitively proved to be valuable tools for community-engaged health research when, in the context of the COVID-19 pandemic, they were integrated into a research study testing a peer support group intervention with female immigrants from Mexico. Because of pandemic restrictions, we changed the study protocol to hold meetings remotely via Zoom rather than in person as originally planned. Because we recognized that this would lack some opportunities for participants to interact and develop relationships, we created a WhatsApp chat for each group. Despite challenges for participants to use ICTs and participant-stated preference for in-person meetings, the results demonstrated that participants overwhelmingly endorsed these technologies as promoting access, participation, engagement, and satisfaction. Zoom/WhatsApp created a valuable environment both as a method for conducting research with this population, but also as part of the intervention for immigrant women to support and learn from each other. ICT adaptations have now permanently changed the way we conduct community-engaged health research.

Blackberry extract prevents lipopolysaccharide-induced depressive-like behavior in female mice: implications for redox status, inflammation, and brain enzymes.

ABSTRACTThis study evaluated the effects of Rubus sp. extract on behavioral and neurochemical parameters in female mice submitted to experimental model of depression induced by lipopolysaccharide (LPS). The results indicated that Rubus sp. extract protected against depressive-like behavior induced by LPS. Moreover, the administration of Rubus sp. extract was effective in preventing the increase in reactive species and nitrites levels, as well as the decrease in catalase activity induced by LPS in the cerebral cortex. In the serum, the Rubus sp. extract was effective in preventing the decrease in catalase activity induced by LPS. Treatment with Rubus sp. extract attenuated the increase in acetylcholinesterase activity induced by LPS in the cerebral cortex. Finally, blackberry extract also downregulated IL-1ß levels in cerebral cortex. In conclusion, our findings demonstrated that treatment with Rubus sp. exerted antidepressant, antioxidant, anticholinesterase and anti-inflammatory effects in a model of depressive - like behavior induced by LPS in female mice. This highlights Rubus sp. as a potential therapeutic agent for individuals with major depressive disorder.

A microRNA Profile Regulates Inflammation-Related Signaling Pathways in Young Women with Locally Advanced Cervical Cancer.

Cervical cancer (CC) remains among the most frequent cancers worldwide despite advances in screening and the development of vaccines against human papillomavirus (HPV), involved in virtually all cases of CC. In mid-income countries, a substantial proportion of the cases are diagnosed in advanced stages, and around 40% of them are diagnosed in women under 49 years, just below the global median age. This suggests that members of this age group share common risk factors, such as chronic inflammation. In this work, we studied samples from 46 patients below 45 years old, searching for a miRNA profile regulating cancer pathways. We found 615 differentially expressed miRNAs between tumor samples and healthy tissues. Through bioinformatic analysis, we found that several of them targeted elements of the JAK/STAT pathway and other inflammation-related pathways. We validated the interactions of miR-30a and miR-34c with JAK1 and STAT3, respectively, through dual-luciferase and expression assays in cervical carcinoma-derived cell lines. Finally, through knockdown experiments, we observed that these miRNAs decreased viability and promoted proliferation in HeLa cells. This work contributes to understanding the mechanisms through which HPV regulates inflammation, in addition to its canonical oncogenic function, and brings attention to the JAK/STAT signaling pathway as a possible diagnostic marker for CC patients younger than 45 years. To our knowledge to date, there has been no previous description of a panel of miRNAs or even ncRNAs in young women with locally advanced cervical cancer.

Evidence of the Existence of Site-Specific Female Contact Pheromones Involved in the Sexual Interaction Behavior of the Pacific Whiteleg Shrimp Penaeus vannamei.

Although the presence of female contact sex pheromones in P. vannamei has been hypothesized, to date its existence has not been proven. To gather more evidence of their existence, cuticular liposoluble extracts were obtained from the following samples of adult females to be used as the experimental treatments: (1) ventral exoskeleton of immature female (VI), (2) dorsolateral exoskeleton of immature female (DI), (3) ventral exoskeleton of mature female (VM), and (4) dorsolateral exoskeleton of mature female (DM). Polyvinyl chloride tubes (artificial females; AF) were coated with each extract and the behavior displayed by sexually mature males in contact with the AF was recorded and classified as follows: 0 = no response; 1 = contact; 2 = pushing; and 3 = prolonged contact (≥10 s). To test the hypothesis that the extracts collected from the ventral portion of the abdomen exoskeleton have a higher effect on the behavior of males than the extracts collected from the dorsolateral portion of the abdomen exoskeleton, the experiment was divided into two bioassays: Bioassay I (VI vs. DI) and Bioassay II (VM vs. DM). In each bioassay, all experimental treatments were significantly different (p > 0.05) from the CTL group (AF coated with hexane). Notably, the pushing behavior was significantly higher (p < 0.05) in the VI treatment compared to the CTL and DI treatment. These results provide evidence of the existence of contact female sex pheromones with sexual recognition function located primarily in the ventral portion of the abdomen exoskeleton of P. vannamei.

Técnica Boomerang para plástica genital estética feminina / Boomerang technique for female genital aesthetic surgery

Introdução: A hipertrofia de pequenos lábios combinada com capuz clitoriano redundante é uma queixa comum entre mulheres que procuram cirurgia plástica genital cosmética por queixas funcionais, psicológicas e estéticas. O objetivo deste estudo foi descrever a técnica boomerang, um tratamento cirúrgico da hipertrofia labial que se estende a todo o capuz clitoriano. Método: Foi conduzido um estudo retrospectivo, de caráter analítico, para avaliar os prontuários médicos de 48 pacientes consecutivas submetidas a cirurgia estética genital feminina entre julho de 2017 e julho de 2021. Todos os procedimentos cirúrgicos foram realizados pela mesma cirurgiã. A técnica utilizada nas pacientes consistiu na ressecção longitudinal dos excessos de pequenos lábios vaginais associado à ressecção de capô clitoriano em forma de boomerang e à clitoropexia. Resultados: A idade média das pacientes submetidas a cirurgia foi de 36,25 anos (intervalo 18-59 anos), entre as quais 94,44% apresentaram queixas estéticas associadas ou não a queixas funcionais, e 5,56% apresentaram somente queixas funcionais. Duas pacientes apresentaram hematomas nos grandes lábios no pós-operatório imediato, e uma paciente teve deiscência de sutura nos pequenos lábios. Conclusão: A técnica boomerang é reprodutível e proporciona benefícios estéticos e/ou funcionais na genitália feminina.

Introduction: Hypertrophy of the labia minora combined with a redundant clitoral hood is a common complaint among women seeking aesthetic genital cosmetic surgery for functional, psychological, and aesthetic complaints. The objective of this study was to describe the boomerang technique, a surgical treatment for labial hypertrophy that extends to the entire clitoral hood. Method: A retrospective, analytical study was conducted to evaluate the medical records of forty-eight consecutive patients who underwent female genital cosmetic surgery between July 2017 and July 2021. The same surgeon performed all surgical procedures. The technique used in the patients consisted of longitudinal resection of excess small vaginal lips associated with resection of the boomerang-shaped clitoral hood associated with clitoroplasty. Results: The average age of patients undergoing surgery was 36.25 years (range 18-59 years), among whom 94.44% had aesthetic complaints associated or not with functional complaints, and 5.56% had only functional complaints. Two patients had bruises on the labia majora in the immediate postoperative period, and one patient had suture dehiscence on the labia minora. Conclusion: The boomerang technique is reproducible and provides aesthetic and/or functional benefits to the female genitalia.

Small-Sided Games vs. High-Intensity Interval Training on Body Composition of Female Handball Players / Juegos Reducidos vs Entrenamiento Interválico de Alta Intensidad sobre la Composición Corporal de Jugadoras de Balonmano

SUMMARY: The purpose of this study was to compare the effects of different training programs based on small-sided games (SSG) and high-intensity interval training (HIIT) on the body composition of female handball players. A total of 45 female handball players (age: 16.13±0.89 years; training experience: 6.18±1.33 years) were assigned to three groups: game group (GG; N = 15), running group (RG; N = 15), and control group (CON; N = 15). The training programs lasted eight weeks, with two training sessions per week. The GG performed three vs. three small-sided games on a 20 m x 20 m court; the RG performed 15 s HIIT running followed by 15 s of active recovery; the CON group maintained regular handball training. Regardless of the group assignment, all participants were measured for each of the following variables: Body height, body mass, fat-free mass, fat mass, muscle mass, intracellular water, and extracellular water. The results demonstrate significant differences (p0.01) in muscle mass. The GG showed significant (p<0.001) greater improvement in these body composition variables than RG and CON. Body composition variables improved with GG, moving from 2.04 % in fat mass to 1.3 % in extracellular water. In the RG, results show significant improvements (p<0.001) only in intra- and extracellular water. The CON shows improvements in fat-free mass, muscle mass, intracellular water, and extracellular water. To conclude, eight weeks of SSG in handball provide better changes in body composition compared to HIIT 15 s - 15 s and handball training alone.

El propósito de este estudio fue comparar los efectos de diferentes programas de entrenamiento basados en juegos reducidos (SSG) y entrenamiento interválico de alta intensidad (HIIT) sobre la composición corporal de jugadoras de balonmano. Un total de 45 jugadoras de balonmano (edad: 16,13 ± 0,89 años; experiencia de entrenamiento: 6,18 ± 1,33 años) fueron asignadas a tres grupos: grupo de juego (GG; N = 15), grupo de carrera (RG; N = 15) y grupo de control (CON; N = 15). Los programas de formación duraron ocho semanas, con dos sesiones de formación por semana. El GG realizó partidos reducidos de tres contra tres en una cancha de 20 x 20 m; el RG realizó 15 s de carrera HIIT seguidos de 15 s de recuperación activa; El grupo CON mantuvo un entrenamiento regular de balonmano. Independientemente de la asignación de grupo, a todos los participantes se les midió cada una de las siguientes variables: altura corporal, masa corporal, masa libre de grasa, masa grasa, masa muscular, agua intracelular y agua extracelular. Los resultados demuestran diferencias significativas (p0,01) en la masa muscular. El GG mostró una mejora significativa (p<0,001) mayor en estas variables de composición corporal que RG y CON. Las variables de composición corporal mejoraron con GG, pasando de un 2,04 % en masa grasa a un 1,3 % en agua extracelular. En el RG, los resultados mostraron mejoras significativas (p<0,001) sólo en el agua intra y extracelular. El CON indicó mejoras en la masa magra, la masa muscular, el agua intracelular y el agua extracelular. En conclusión, ocho semanas de SSG en balonmano proporcionan mejores cambios en la composición corporal en comparación con el HIIT de 15 s - 15 s y el entrenamiento de balonmano solo.

Reviving forgotten techniques: Vaginal salpingectomy in public health system, a retrospective cohort study.

OBJECTIVE: To evaluate the viability of the vaginal route as an alternative to laparoscopy for patients seeking permanent surgical contraception. METHODS: We conducted a retrospective cohort study in 2021, dividing patients into two groups based on their preference: vaginal and laparoscopic salpingectomy. The statistical analysis was conducted using STATA, employing standard statistical methods based on the distribution of variables. RESULTS: The study included 64 patients, with 34 undergoing the vaginal approach and 30 the laparoscopic route. No statistically significant differences were observed in baseline characteristics or complications between the two groups. Both surgical methods were found to be feasible. The vaginal route demonstrated a significantly shorter mean surgical time (P < 0.001). The laparoscopic route exhibited significantly less intraoperative blood loss (P < 0.001) and fewer hospitalization hours (P = 0.008). Postoperative satisfaction and pain levels did not show statistically significant differences. CONCLUSION: Vaginal salpingectomy is a feasible technique with low complication rates, making it a potential option for gynecologists to offer their patients. We propose vaginal route inclusion in the training curriculum for gynecologic surgeons during the residency program, without any subspecialty requirements.

Scientific Output by Latin American Women in Pediatric Surgical Sciences Over the Past 11 Years: A Bibliometric and Visual Analysis.

INTRODUCTION: This academic article discusses the historical underrepresentation of female in science, with a focus on Latin America. It highlights the importance of both technical and non-technical skills in the medical-surgical field, particularly the role of research skills. The study aims to quantify and characterize the scientific output of Latin American female researchers over the past decade, providing insights into the challenges and opportunities in low and middle-income countries. MATERIAL AND METHODS: A retrospective cross-sectional bibliometric study was conducted in 2023, focusing on pediatric surgical science journals in Scopus and PubMed. It assessed Latin American female participation, journal details, and interaction networks, using SPSS and Gephi software. The period analyzed was from January 2012 to December 2022. RESULTS: Between 2012 and 2022, 727 articles with Latin authorship in pediatric surgery were analyzed across 304 journals. Of these, 63.69% had female co-authors. The majority were original articles (53.13%), with contributions from Brazil, Mexico, and Chile. Notable journals included the Journal of Pediatric Surgery and Child's Nervous System. Keywords like Laparoscopy and Cardiac surgery were common. A growth trend in female Latin American publications was observed, despite temporary declines. CONCLUSIONS: This study highlights a growing trend in Latin American females' scientific contributions to pediatric surgery from 2012 to 2022, although a gender gap persists. The research mainly consists of primary data studies, with a focus on Brazil and Mexico from public institutions. The Journal of Pediatric Surgery featured prominently, and common topics included Laparoscopy, Cardiac surgery, Liver transplant, Congenital heart defects, and COVID-19. LEVEL OF EVIDENCE: IV.

The personal experience of female obstetricians and gynaecologists with contraceptive use influences the guidance and prescription of contraceptive methods: a web-survey.

OBJECTIVE: To evaluate the influence of the personal experience of female obstetricians and gynaecologists (Obst/Gyns) who utilise contraceptive methods on the provision of these methods. METHODS: An anonymous online web-based survey was carried out with female Obst/Gyns. The instrument contained questions about their current and previous contraceptive methods use, factors that influenced the choice and satisfaction with the ongoing method, as well as the occurrence of adverse events. They were also asked whether the experience of any adverse events influenced their decision in prescribing any particular contraceptive method. RESULTS: 476/9000 (5.3%) female Obst/Gyns answered the survey. The most common contraceptive in use was the 52-mg levonorgestrel-intrauterine device (52-mg LNG-IUD) (34%), followed by non-Long-Acting Reversible Contraception hormonal methods (21.2%). More than half of the respondents (57.6%) reported having some adverse effects and 18.7% reported that the personal experience of an adverse effect with the use of a contraceptive method influenced the prescription of that method. CONCLUSION: Half of female Obst/Gyns encountered adverse events linked to contraceptive usage. Additionally, almost one-fifth believe that their own encounter with adverse effects from a contraceptive method impacts their decision to prescribe the same method.

Almost one-fifth of the female obstetrics and gynaecologists that answered the online survey reported that the personal experience of an adverse effect with the use of a contraceptive method influenced the prescription of that method.

Discrimination against the female surgeon in the exercise of her profession.

OBJECTIVE: To describe the discrimination experienced by the general female surgeon. METHOD: Prospective, cross-sectional and descriptive study, with a survey of 30 questions, closed, anonymous, voluntary and confidential, distributed through a link in the WhatsApp chat in a closed group of female surgeons who are members of the Asociación Mexicana de Cirugía General. RESULTS: 146 female surgeons participated, with a response rate of 58.4%. The discrimination perceived by female surgeons in training was 86 (58.9%), and 28 (19.2%) when they are already surgeons by not allowing them to perform the same procedures as their peers. Regarding the patients, discrimination against female surgeons was 72 (49.3%). They do not call them doctors, but "ladies", in 126 (86.3%), and they are asked to perform nursing duties in 120 (82.2%). On the other hand, there is also discrimination against female surgeons by nursing staff in 87 (59.6%). CONCLUSIONS: Discrimination is common in the daily surgical practice of female surgeons in all three areas: peers, patients, and nursing staff. This is an initial work, where the quantification of discrimination in Mexico is carried out. Strategies must be implemented to avoid discrimination against female surgeons and be in an environment of equality.

OBJETIVO: Describir la discriminación que vive la cirujana general en México. MÉTODO: Estudio prospectivo, transversal y descriptivo, con una encuesta de 30 preguntas cerradas, de manera anónima, voluntaria y confidencial, distribuida a través de un enlace en el chat de WhatsApp en un grupo cerrado de cirujanas de todo el país que son miembros de la Asociación Mexicana de Cirugía General. RESULTADOS: Participaron 146 cirujanas, con un porcentaje de respuesta del 58.4%. La discriminación percibida por las cirujanas en formación fue de 86 (58.9%), frente a 28 (19.2%) cuando ya son cirujanas, al no permitirles realizar los mismos procedimientos que sus pares. La discriminación por parte de los pacientes fue de 72 (49.3%). No las llaman doctoras sino «señoritas¼ en 126 (86.3%) y les solicitan hacer funciones de enfermería en 120 (82.2%). También existe discriminación hacia las cirujanas por el personal de enfermería en 87 (59.6%). CONCLUSIONES: La discriminación hacia las cirujanas es frecuente en los tres ámbitos: pares, pacientes y personal de enfermería. Este es un trabajo inicial, donde se realiza la cuantificación de la discriminación en México. Se deberán implementar las estrategias para evitar la discriminación a las cirujanas y estar en un ambiente de igualdad.
