Relationship in stages of development with age between living male children and male adults through measurement of sternum bone in Lucknow City of U.P

The ideal rule of identification of sex and age is a sever need in medico legal cases. Sternum is much more appropriate for detection of sex and age of human beings separately from racial characters. In present study, our objectives were to find out the age and gender on the basis of sternum length in living male children and adults. This study has been conducted on the total 100 subjects, 50 male children (02-15 yrs) and 50 male adult (16-60yrs) of healthy people (living children & adults) from general population of north India as well as in and around the Lucknow of Uttar Pradesh. The technique described by Ashley GT -1956b was used for measurement of sternum. Comparing the mean length, Student’s t test showed significantly different and higher length of manubrium (16.1%) (49.45 ± 3.45 vs. 58.97 ± 6.68, t=8.94, p<0.001) and length of sternum (4.0%) (156.16 ± 5.26 vs. 162.70 ± 5.70, t=5.97, p<0.001) in 16-60 yrs as compared to 2-15 yrs. The assessment of the relationship in stage of development and sex between living male children and adult through measurement of sternum bone in lucknow city of U.P., significantly different and higher length of sternum, because the growth of sternum segment was completely develop in adult, but the development in children male is continuous in ratio of adults male.

Towards women's digital health equity: A qualitative inquiry into attitude and adoption of reproductive mHealth services in Bangladesh.

Health equity in Bangladesh faces a large chasm over the economic conditions, socio-cultural factors and geographic location despite the push for digitalization of the health sector. While some research has been conducted assessing the viability of digital health solutions in Bangladesh, gender dynamics of digital healthcare have been absent. This study dived into healthcare equity for women with a focus on reproductive health services delivered through mobile devices. This paper reported the findings of a qualitative study employing in-depth interviews conducted among 26 women about their behavioral intention to use mHealth services for reproductive health and the underlying factors influencing this intention with the help of the Integrative Model of Planned Behavior (IMPB). A snowball sampling technique were used to interview those university educated women, aged 21-31, based on their familiarity and exposure of mHealth services from seven universities in Bangladesh. The findings suggested that users of mHealth services find it more convenient and secure compared to visiting healthcare facilities, especially for trivial issues and inquiries regarding their reproductive health. Although promoting such services is lagging behind traditional healthcare, the attitude toward reproductive health services in Bangladesh is generally favorable resulting increasing adoption and use. Because such information-related mobile services (apps, websites, and social media) served as a first base of knowledge on reproductive health among many young girls and women in Bangladesh, who are generally shy to share or talk about their menstruation or personal health problems with family members, peers, or even health professionals due to socio-cultural factors and stigmatization. Conversely, urban centric services, availability of experts, quality management, security of privacy, authenticity of the information, digital divide, lack of campaign initiatives, lack of equipment and technology, lack of sex education, and outdated apps and websites were identified as obstacles that constrain the widespread use of reproductive mHealth services in Bangladesh. This study also concluded that promotion will be crucial in reforming conservative norms, taboos, and misconceptions about women's health and recommended such endeavors to be initiated by the policy makers as there is a substantive need for a specific policy regulating emerging digital health market in Bangladesh. Notwithstanding, women-only sample, low sample size, narrow focus on mHealth users and absence of perspectives from healthcare providers were among shortcomings of this study which could be addressed in future research. Further quantitative explorations are must to determine the usage patterns of reproductive mHealth services and their effectiveness that would identify implementation challenges in terms of customization and personalization in reproductive healthcare in a developing country like Bangladesh.

Identification of sex-specific markers using genome re-sequencing in the blunt snout bream (Megalobrama amblycephala)

BackgroundThe blunt snout bream (Megalobrama amblycephala) is an important economic freshwater fish in China with tender flesh and high nutritional value. With the cultivation of superior new varieties and the expansion of breeding scale, it becomes imperative to employ sex-control technology to cultivate monosexual populations of M. amblycephala, thereby preventing the deterioration of desirable traits. The development of specific markers capable of accurately identifying the sex of M. amblycephala would facilitate the determination of the genetic sex of the breeding population before gonad maturation, thereby expediting the processes of sex-controlled breeding of M. amblycephala.ResultsA whole-genome re-sequencing was performed for 116 females and 141 males M. amblycephala collected from nine populations. Seven candidate male-specific sequences were identified through comparative analysis of male and female genomes, which were further compared with the sequencing data of 257 individuals, and finally three male-specific sequences were generated. These three sequences were further validated by PCR amplification in 32 males and 32 females to confirm their potential as male-specific molecular markers for M. amblycephala. One of these markers showed potential applicability in M. pellegrini as well, enabling males to be identified using this specific molecular marker.ConclusionsThe study provides a high-efficiency and cost-effective approach for the genetic sex identification in two species of Megalobrama. The developed markers in this study have great potential in facilitating sex-controlled breeding of M. amblycephala and M. pellegrini, while also contributing valuable insights into the underlying mechanisms of fish sex determination.

Applying the Theory of Planned Behavior in Sexuality Education: Educators’ Behavioral Intentions Toward Sexuality Issues

Grounded on Ajzen’s theory of planned behavior (1991), the current project in two studies (N = 402) examined Greek and Spanish pre-service early childhood educators’ behavioral intentions (i.e., approach and avoidance intentions) toward young children’s sexual curiosities. Specifically, the current research project aimed to examine whether Greek and Spanish pre-service early childhood educators’ views on sexuality education were linked to their behavioral intentions toward children’s sexual curiosities. The current research also examined whether conservative ideology (religiosity and right-wing political orientation) moderates the link between educators’ views and their behavioral intentions. This study’s findings showed that educators’ views influence their behavioral intentions toward children’s curiosity about sexual issues. In addition, moderation analysis showed religiosity’s role in avoidance intention. This result provides evidence that there are theoretical and empirical grounds to assume that conservative worldviews (i.e., religiosity) significantly influence behavioral intentions concerning sexuality education. The theory of planned behavior not only represents the factors influencing intention but also provides an opportunity to comprehend the impacts of contextual and individual background elements that may be relevant to a particular behavior.

A qualitative study on perceptions of adolescents' sexual and reproductive health education in Yogyakarta, Indonesia.

Sexual and reproductive health (SRH) education in Yogyakarta, Indonesia, is contentious due to societal and religious taboos in the Javanese Muslim community and being misunderstood as a potential catalyst for the premarital sex of unmarried adolescents. The existing practice of SRH education cannot guarantee reliable information about adolescent sexuality. The research aims to understand the intergenerational perception of SRH education conducted at high schools, which has not been comprehensively researched. This qualitative study was conducted in 2016 to explore the perspectives of adults and adolescents regarding school-based SRH education. Focus group discussions and individual interviews were used for data collection, while data analysis was conducted using a feminist perspective. The study identified gaps in the delivery of SRH education among Javanese Muslim, Indonesia. SRH education had not adequately addressed how adults and adolescents perceived sexuality as taboo due to moral panic about premarital sex and societal expectations placed on girls to maintain their virginity. Peer counsellors, responsible for imparting SRH information and facilitating communication with adolescents, reproduced adult moral values toward their peers, leading to a reluctance among adolescents to share their issues. Consequently, SRH education failed to reach those experiencing unwanted pregnancy or a toxic intimate relationship. The results of the study indicate the need to challenge intergenerational perceptions regarding sexuality and gender expectations to promote a positive gender perspective within SRH education in Indonesia.

Large Language Models in an App: Conducting a Qualitative Synthetic Data Analysis of How Snapchat’s “My AI” Responds to Questions About Sexual Consent, Sexual Refusals, Sexual Assault, and Sexting

ABSTRACT Comprehensive sexual health education for young people often remains largely inaccessible, leaving gaps in knowledge about sexual consent, refusals, sexual assault, and sexting. Snapchat’s My AI, tailored to its users, offers accessible and potentially stigma-free responses to sexual health queries, showing promise in addressing these gaps. This study aimed to evaluate My AI’s effectiveness in handling questions related to sexual communication, assault, and sexting, and its response consistency across users. Collaborating with young adults and leveraging prior literature, our team formulated questions on sexual consent, refusals, sexual assault, and sexting submitted to My AI by 15 researchers. Each team member opened a chat with My AI in Snapchat and asked it a set of questions in the same order. We then conducted a qualitative content analysis to assess for consistency across users. My AI responses emphasized the importance of clear, honest consent and refusal communication through physical contact or direct conversation. With potential experiences of sexual assault or sexting, it advised consultation with a trusted caregiver. While My AI provided similar responses across researchers, variations were noted. My AI’s responses mirrored common sexual health education messages and the responses used language reflective of sympathy toward potential assault victims or those who were asked for sexual images. My AI’s potential to enhance accessibility to sexual health information could empower young people in making informed sexual health decisions. However, variability in responses may limit impact and comprehension, underscoring the importance of educators complementing these tools.

Gestational exposure to organophosphate esters and autism spectrum disorder and other non-typical development in a cohort with elevated familial likelihood

BackgroundGestational exposure to organophosphate esters (OPEs) is known to affect offspring neurodevelopment in animal studies. However, epidemiological evidence is inconsistent. MethodsParticipants were 277 mother-child pairs from MARBLES (Markers of Autism Risk in Babies – Learning Early Signs), a cohort with elevated familial likelihood of autism spectrum disorder (ASD). Nine OPE biomarker concentrations were quantified in maternal urine collected during the 2nd or 3rd trimesters of pregnancy. At age 3 years, children underwent clinical assessment for ASD and were classified into ASD, other non-typical development (non-TD), or typical development (TD). Multinomial logistic regression was used to estimate associations between each OPE biomarker and relative risk ratios for ASD and non-TD compared to TD. We examined effect modification by child sex and socioeconomic status. We also conducted a secondary analysis by using a continuous measure of ASD symptom severity as an outcome. Quantile-based g-computation was performed to examine the associations for an OPE mixture. ResultsOverall, no significant association was observed between the concentrations of each OPE biomarker or their mixture and relative risk for either ASD or non-TD. Effect modifications by child sex and maternal education were not observed. When the analysis was stratified by homeownership, among non-homeowners, ASD likelihood was increased with increased levels of bis(1-chloro-2-propyl) phosphate, bis(butoxyethyl) phosphate, and sum of di-n-butyl phosphate and di-iso-butyl phosphate (DBUP/DIBP) (pint < 0.10). Higher DBUP/DIBP were associated with increased ASD symptom severity scores. ConclusionThere was no clear evidence of gestational OPE exposure in association with relative risk for ASD; however, potential effect modification by homeownership was observed. Although our cohort includes children with elevated familial likelihood of ASD, this is the first study investigating the association between gestational OPE exposure and clinically-diagnosed ASD. Further research is needed to confirm our findings in the general population.

Sex Education Training as Capacity Building Tool for Mothers and their Children with Intellectual Disability: A Qualitative Study

Sex is a biological need of human beings and the aspects of sexuality and sexual development are less discussed in people with intellectual disability (ID). Sex education training (SET) for persons with ID and their parents is pivotal in mitigating challenges and creating a safe and healthy space for expressing their sexual needs. The aim was (a) to see the effects of SET in the enhancement of knowledge and skills about sexual health among adults with ID, (b) To see the effect of mothers as an observer during SET on their perception, attitude and practice on sexual health for their children with ID. The sample consisted of 11 mothers and their children who were above 18 years with ID. Awareness of sexual health education for parents of intellectually challenged children and family life and sexual health assessment tools were used. A qualitative/descriptive analysis was done. SET was started for the period of three months, two sessions in a week, each session lasting one and half hours. It was done in a playful manner on self and social awareness, safe/unsafe touch, relationships, personal safety rules and sexual harassment of women at workplace (POSH). SET shows not only enhancement in the level of awareness, knowledge on sexual health but also improved communication skills and decision-making skills among adults with ID and their mothers. Mothers feel more confident and comfortable to have open discussions with their children on sexual health.

Evaluation of the Sources of Sexual Knowledge and Information among Men in Kenya

AbstractSources of sexual knowledge and information among men have impact on quality of their sexual literacy and decision making. Sexual knowledge impacts on sexual attitudes, which underpin sexual behaviours and in turn impacts the sexual health outcomes of men. A cross-sectional quantitative survey was used to assess the sources of sexual knowledge and information among 484 Kenyan adult men aged 18–54. Data analysis was performed with STATA-16. Results showed that 79% of men learned about sex from school-based sex education, 75% and 72% from peers and mass media respectively while healthcare professionals (35%) and parents (28%) had the lowest influence on sexual knowledge and information. Understanding men’s sources of sexual knowledge and information that informs their sexual decision making can influence sexuality education planning and sexological practice policies targeted to out of school youths and older men. Hence, appraising formal peer educator’s knowledge could provide transformative sexual and reproductive health support services to men.

Perceived usefulness of sex and relationship education sources among sexual minority men

ABSTRACT Intimacy and relationships are important to sexual minority men, yet traditional sex and relationship education from sources such as schools and families may lack perceived usefulness. Consequently, sexual minority men may seek information from alternative sources, but little research has explored the usefulness of these alternatives. A national survey of sexual minority men in Australia (n = 936, Mage = 38.9) evaluated the usefulness of seven sources of information: school programmes, family, peers and friends, social media and the Internet, popular culture, pornography, and official information sources. Five topics were examined for each source: sexual and reproductive physiology, HIV/STI prevention, relationship skills, consent and needs negotiation, and sexual and intimate behaviours. Participants rated the sources as minimally to moderately useful. Official information sources were rated most useful, followed by peers and friends, social media and the Internet, popular culture, pornography, school, and family. Older men found most sources less useful than younger participants. Perceived usefulness varied across topics (e.g. popular culture and peers and friends rated most useful for relationship skills). These findings underscore the limited relevance of conventional sex and relationship education for sexual minority men and highlight the need for enhanced education programmes.

Towards transforming malaria vector surveillance using VectorBrain: a novel convolutional neural network for mosquito species, sex, and abdomen status identifications

Malaria is a major public health concern, causing significant morbidity and mortality globally. Monitoring the local population density and diversity of the vectors transmitting malaria is critical to implementing targeted control strategies. However, the current manual identification of mosquitoes is a time-consuming and intensive task, posing challenges in low-resource areas like sub-Saharan Africa; in addition, existing automated identification methods lack scalability, mobile deployability, and field-test validity. To address these bottlenecks, a mosquito image database with fresh wild-caught specimens using basic smartphones is introduced, and we present a novel CNN-based architecture, VectorBrain, designed for identifying the species, sex, and abdomen status of a mosquito concurrently while being efficient and lightweight in computation and size. Overall, our proposed approach achieves 94.44±2% accuracy with a macro-averaged F1 score of 94.10±2% for the species classification, 97.66±1% accuracy with a macro-averaged F1 score of 96.17±1% for the sex classification, and 82.20±3.1% accuracy with a macro-averaged F1 score of 81.17±3% for the abdominal status classification. VectorBrain running on local mobile devices, paired with a low-cost handheld imaging tool, is promising in transforming the mosquito vector surveillance programs by reducing the burden of expertise required and facilitating timely response based on accurate monitoring.

The Perceived Inclusivity of Sex Education Scale – 2: Sex Education Inclusivity and Health Outcomes Among Gender Diverse Individuals

Past research has documented a relationship between sex education inclusivity and health outcomes among sexually diverse youth (e.g., lesbian, gay, bisexual, queer). However, despite transgender and gender diverse (TGD) individuals also being regularly excluded from sex education, little research has explored this relationship among TGD people. In the current study, the Perceived Inclusivity of Sex Education Scale − 2 (PISES-2) was developed to better understand the associations between perceived sex education climate and both mental and behavioral health outcomes. TGD individuals (N = 162) were recruited to participate in an online survey to examine these associations. Results suggested that greater levels of perceived inclusivity of sex education were associated with lower levels of depression, anxiety, and suicidality in high school and post-high school. Additionally, greater levels of inclusivity of sex education were associated with increased sexual behaviors and less hesitancy toward sex in TGD individuals in high school and post-high school. These conclusions add to the growing literature highlighting the critical importance of inclusive and affirming sex education for the safety and well-being of TGD individuals.

Identification of two effective sex-specific DNA markers in silver arowana (Osteoglossum bicirrhosum)

The silver arowana (Osteoglossum bicirrhosum), often referred to as a living fossil, presents significant challenges in sex identification based on morphological characteristics, with its sex determination mechanism remaining poorly understood. This issue poses considerable obstacles to its captive breeding efforts. Given the species' substantial value for both consumption and ornamental purposes, it is a critical candidate for aquaculture. Through genome sequencing, read mapping, and alignment analysis of five male and five female silver arowanas, along with one mixed pool of males, we successfully identified two sex-specific SNPs and confirmed a ZW model of sex determination in this ancient species. These two SNPs demonstrated remarkable accuracy, achieving 100 % success in genetic sex identification, as validated by Sanger sequencing of PCR products from 135 individuals. Both sex-specific SNPs are located approximately 26 kb upstream of the foxl2 gene, indicating a potentially pivotal role for the foxl2 gene in the sex-determination process of the silver arowana. Consequently, we have developed precise molecular markers for sex identification in the silver arowana, significantly enhancing reproductive efficiency and promoting further industrial development. This achievement lays a foundational basis for investigating the sex-determination mechanism of the silver arowana and other osteoglossid fish, thereby advancing aquaculture practices within this species.

Ultrasonography for non-invasive sex identification and reproductive assessment in Nile tilapia (Oreochromis niloticus).

Sex identification and the selection of monosex male tilapia are crucial for tilapia aquaculture. In this study, we evaluated the application of ultrasonography as an alternative procedure for sex identification and reproductive assessment in Nile tilapia (Oreochromis niloticus). Ultrasonography was performed on 23 fish weighing 232-1,281 g to capture longitudinal and transverse images of the ovaries and testes. Female tilapia were identified by the presence of numerous small egg granules and gray or light gray ovarian tissue and male tilapia by the homogeneous echogenicity and uniform gray tubular appearance of the testes. These distinct echogenic patterns allowed for accurate differentiation between the female and male fish. Ultrasonography achieved a 95% accuracy in sex identification, with minimal stress to the fish during the procedure, compared to manual sex sorting, which demonstrated an accuracy of 87%. Furthermore, the method facilitated the assessment of the reproductive status of the fish, including the maturation stages and fecundity potential. The use of ultrasonography offers significant advantages over traditional methods, such as animal welfare enhancements and improved breeding program efficiency. Our findings support the integration of ultrasonography into aquaculture practices and will promote sustainable and humane fish farming while optimizing reproductive management and productivity.

What Are the Most Popular Articles in Urogynecology and Who Is Disseminating Them

Importance This research describes which articles published in Urogynecology are garnering the most attention online. Understanding which articles are having the largest impact in the online community has become increasingly important due to the exponential increase in the use of social media on the internet. Objective The Altmetric Attention Score (AAS) is a quantitative and qualitative measure of the articles’ online attention in social media and news outlets, blogs, and reference managers. The aim of this study was to provide an analysis of those accessing and sharing the 100 most popular articles published in Urogynecology. Study Design This was a retrospective descriptive analysis. Using Dimensions, a “linked research knowledge system,” data about each article’s demographics on Twitter and other media sources was extracted from each of the articles within Urogynecology with the highest AAS. No articles were excluded. The articles were categorized by topic and metrics of online sharing were compared among categories. Results Fifteen categories were created. Sexual health and education articles had the highest average Altmetric scores per article and reached the highest impressions per article and had the highest average follower count per Twitter user. On average, social justice in medicine had the highest number of tweets per article. Tweets were most often composed by members of the public (58%) compared with health care practitioners (14%), researchers (13%), and science communicators (12%). Conclusions Sexual health and education articles had the highest average AAS and impressions on Twitter. We observed a difference in which articles are being shared most among the general public and health care professionals. The general public comprised a majority of those sharing articles online regardless of category. Additionally, there may be a disparity in research, its funding, and online scientific communications within the field of urogynecology.

Scientific databases and grey literature will be used, and the following keywords will be applied: amelogenin, analyses, sex determination, and human identification. This scoping review will include in vitro studies concerning the goal of this review. This scoping review will deepen our knowledge concerning using teeth and amelogenin genes in sex identification in a forensic context. According to the available data, it will help implement guidelines for human remains identification. This protocol was registered with the Open Science Framework.

Implementation of Sexual and Reproductive Health Education Policy in Schools in Asia and Africa: A Scoping Review

Objectives: This review aimed to map and synthesize existing literature on sex and reproductive education policy implementation in primary and secondary schools in Asia and Africa. Methods: Database searches yielded 24 relevant articles, which underwent thematic analysis. Results: Most studies were conducted in Africa and looked at barriers to implementation. Studies assessing implementation showed it was incomprehensive. Barriers were: policy/curriculum issues, societal opinions, teaching discomfort, lack of educator training, and lack of sufficient economical support. Conclusions: Based on the limited evidence, a cultural shift to reduce stigma seems necessary, alongside teacher and student involvement in policy formulation and implementation monitoring.

Exploring lifestyle components and associated factors in newly injured individuals with spinal cord injury.

Cross-sectional analysis from the Inception Cohort of the Swiss Spinal Cord Injury Study (SwiSCI). To describe five lifestyle components in newly injured individuals with spinal cord injury (SCI), explore co-occurrence of these components, and identify associated personal and clinical factors. Initial rehabilitation stay following traumatic and non-traumatic SCI. Lifestyle components including overweight/obesity, low diet score, physical inactivity, smoking, and alcohol consumption were used independently and to calculate a composite lifestyle score. Analyses were conducted using descriptive statistics, co-occurrence analysis, and multivariate logistic regression. We included 251 individuals, of whom 77.7% were male, 73.7% suffered from traumatic SCI, and 59.8% had paraplegia. The median age was 51 years (IQR 36-64). Approximately twelve weeks after the injury, more than two-thirds of the study population met the criteria for overweight/obesity, and consumed insufficient amounts of fruits and vegetables, and excessive amounts of meat. Alcohol was consumed by 85.3% of individuals, and 26.8% were current smokers. Almost all study participants met the physical activity guidelines (90 min of moderate to strenuous activity physical activity per week). One-quarter of study participants experienced the co-occurrence of overweight/obesity, low diet score and alcohol consumption. Female sex, younger age and higher education were associated with healthier lifestyle components. Despite methodological limitations, this study underscores the complexities of healthy lifestyle adherence among individuals newly injured with SCI. It highlights the necessity of improving and implementing screening strategies throughout the continuum of SCI care as early as possible following the trauma.

The reasons for and influences of unintended teenage pregnancy in Kericho county, Kenya: a qualitative study.

Unintended teenage pregnancies are associated with greater health and socio-economic risks for teenage mothers and newborns. In Kenya, the government has declared a target for ending teenage pregnancy by 2030. However, the prevalence of teenage pregnancy has only decreased slightly, demonstrating the need for further efforts. Understanding teenage mothers' own experiences and perspectives is necessary to design appropriate interventions. A community-based qualitative study was conducted from March to May 2023. Two focus group discussions were conducted with community health volunteers and the mothers of teenage girls. Semi-structured interviews were conducted on the case histories of 19 teenage mothers and 18 key informants. Thematic analysis was subsequently performed using MAXQDA 2022. Four major reasons emerged for unintended teenage pregnancies: (1) lack of knowledge or awareness about the human reproductive system, (2) lack of knowledge about family planning (FP), (3) financial challenges, and (4) low access to FP. At the study site, cultural norms and stereotypes, such as "infertility caused by FP," "freedom of sex by promoting FP," and "cultural taboos on having sex before marriage and talking about sexuality," were observed as barriers in promoting FP to teenagers. In addition, teenagers from low socio-economic backgrounds were found to be more vulnerable because they can be easily exploited by men who can afford to provide for some of their basic needs. Regarding the influences of unintended teenage pregnancy on teenage mothers' lives, the 19 cases were classified into four categories: (1) dropping out of school, (2) financial challenges, (3) changing relationships with parents, and (4) no major influence. Crucially, unintended teenage pregnancies negatively influenced most study participants. Continuing education, supportive parental attitudes, positive perceptions of the relationship with the child's father, and having future perspectives were identified as factors mitigating the negative influences. Strengthening culturally appropriate comprehensive sexuality education and the school re-entry policy with a supportive environment may prevent unintended teenage pregnancy and mitigate its negative influences. As financial challenges can be both a reason for and a negative influence of unintended teenage pregnancy, economic empowerment interventions are necessary.
