China has established the basic rules of informed consent in the medical field through Articles 1219 and 1220 of the tort liability part of the Civil Code of China to address the legality of medical conduct.Since patients’capacity to consent is the prerequisite,when the patient is a fully competent person,it is sufficient to give consent based on valid notification by the doctor.However,for those who are unable to give valid consent,especially adult patients with impaired capacity,resolving the legality of the doctor’s medical conduct remains an issue when it infringes on the patient’s body and health.To solve this issue,someone must give consent in place of the patient when the adult is unable to give valid consent.However,the personal and exclusive nature of the right to medical consent,which is informed consent,makes it impossible to simply delegate it to a guardian or other person to exercise it on behalf of the patient.In this paper,we borrow the concept of“medical proxy”proposed by Japanese scholar Teruaki Tayama,and for the first time,we discuss the construction of medical proxy from the perspective of adult guardianship by connecting the two systems from the standpoint of interpretive theory. 展开更多

Introduction: In many societies, sexuality is still a taboo subject. In the Central African Republic, this topic is rarely discussed outside the context of gynecological consultations and infertility, whereas the sexual life of couples is often disrupted by the arrival of a child, particularly by the ordeal of childbirth. The aim of the study is to analyze the sexual experience of Central African women after childbirth in order to contribute to improving the health of the population, in particular that of mother and child, and to facilitate harmony within the couple. Methodology: Descriptive and analytical cross-sectional study covering the period from July 1 to August 30, 2023, at the maternity ward of the Center University Hospitalier Communautaire. The study concerned only women who had given birth between the second week and the sixth month postpartum. The sampling was exhaustive. Results: A total of 303 women agreed to take part in our study, aged between 15 and 44, more than half of whom had completed secondary school. The eagerness of the women to take part in the study shows that they are ready to express themselves about their sexuality despite certain biases linked to the method of patient selection. Resumption of sexual relations was initiated by the partners within six weeks in the vast majority of cases. Conclusion: Resumption of sexual intercourse was delayed, often at the partner’s initiative. Further studies are needed to understand the cultural, religious and psychological dimensions of postpartum sexuality in the Central African context. 展开更多

Objective: Sexual violence affects women of all ages but, more commonly, children and adolescents. This study aimed to identify the extent to which services are being provided at the hospitals responsible for the emergency care of children and adolescents who have suffered sexual violence and to determine whether there is any difference in the provision of such services as a function of the victim’s age. Method: This cross-sectional study investigated differences in the care received by female children and adolescents who are victims of sexual violence in a capital city, comparing the treatment given to girls under 15 with that given to adolescents of 15 to 19 years of age. The data were extracted from the State Department of Health database between 01/01/2012 and 31/12/2016. Results: Children under 15 were much less likely to receive prophylaxis against HIV, sexually transmitted infections and hepatitis B, with the number of adolescent girls treated adequately corresponding to between twice and almost three times the number of children treated prophylactically. Only 10% of girls under 15 received emergency contraception. Conclusion: The lack of standard care established by the Ministry of Health highlights the need for urgent debates both locally and probably throughout the country, as the situation may be similar in other regions of the country. 展开更多

We studied sexual dimorphism in body size and shape and female reproductive characteristics in the Hainan Water Skink(Tropidophorus hainanus)from Hainan,South China.In our sample the largest female and male were 61.1 and 55.2 mm snout-vent length(SVL),respectively.The mean SVL was larger in adult females(52.0 mm)than in adult males(48.3 mm).Juveniles were sexually dimorphic in head length but not in other examined morphological variables.Adult males were longer in head length and shorter in abdomen length and fore-limb length than adult females of the same SVL.Ontogenetic shifts in sexual dimorphism in body shape were evident,as revealed by the fact that morphological differences between the sexes were more pronounced in adults than in juveniles.Females produced a single litter of 3–6 offspring per season from early August to early September.Litter size,litter mass and offspring(neonate)mass were positively related to female SVL.Neonate mass was independent of relative fecundity.From the above findings we draw three main conclusions.First,females are the larger sex in T.hainanus,and sexual dimorphism in body shape is more pronounced in adults than in juveniles.Second,larger female T.hainanus produce more and larger offspring and thus heavier litters than smaller ones.Third,the offspring size-number trade-off does is not evident in T.hainanus. 展开更多

Objective:To conduct changes in sexual activity during pregnancy and its related factors in pregnant women.Methods:The present descriptive cross-sectional study was conducted in 2017 on pregnant women who referred to the women's clinic of Afzalipour Hospital in the southeast of Iran.Participants were included in the study through convenient sampling.The data collection tool was a researcher-made questionnaire consisting of two parts of personal social information of the couple and questions to measure the level of sexual activity and the attitude of the subjects during pregnancy compared to before pregnancy.Results:201 Pregnant women were included.The average age of pregnant women was(27.3±6.1)years and their average gestational age was(24.7±11.8)years.More than 62%of women had decreased sexual activity.There was a significant relationship between the amount of changes in sexual activity and delivery time(P=0.013),abortion history(P=0.001)and premature birth history(P=0.002).Most pregnant women believed that sex during pregnancy caused damage to the fetus(67.7%).A decrease in the intensity of sexual desire was reported in 63%of pregnant women.More than 60%of the subjects did not consult with doctors and midwives with regards to sexual issues(63.5%).The most common reason for not consulting was not feeling the need(32%).Most women experienced back pain during(42.8%)and after(39.8%)intercourse.Conclusions:Changes in sex life during pregnancy are often caused by the lack of sexual knowledge and the increase in misconceptions among couples,which can affect the quality of relationships.The role of education is essential.Therefore,it is suggested that by including sexual counseling along with pregnancy care,wrong beliefs and information among women will be corrected. 展开更多

Few studies have been carried out on the sexuality of HIA. This study aimed to assess the sexual behavior of HIV-infected adolescents in Cameroon. Methodology: A cross-sectional study was conducted in three hospitals in the cities of Yaoundé and Douala, from November 2019 to June 2020. All HIA aged 13 to 19 years followed in the study who knew their HIV status were included in the study after obtaining their assent and their parent’s consent. Socio-demographic and clinical characteristics were collected, as well as sexual practices and the determinants of their sexual activity. A multivariate analysis was performed to explore the relationship between the different variables studied and the sexual activity of these adolescents. Results: Of 204 HIA enrolled in the study, 64 (31.7%) were sexually active, the mean age at first sexual intercourse was 15.6 ± 2.8 years and the sex ratio was 0.94. Of the adolescents in the study, 75.7% of girls and 61.2% of boys had regular sexual activity, while 21.3% of girls and 35.4% of boys had multiple sexual relationships in the six months preceding the study. Nearly 16 (25.0%) of the sexually active HIA had more than 2 sexual encounters per month, 6 (9.3%) of these encounters had been paid for and 9 (27.2%) of the girls had already had at least one pregnancy. More than 7 out of 10 HIA (79.6%) had used a condom the last time they had sex. Age less than 18 years [OR = 11.1 (95% CI: 3.1 - 39.4), p = 0.001], lack of remuneration [OR = 9.8 (95% CI: 2.0 - 47.4), p = 0.001] and self-care were significantly associated with sexual activity in HIA, while school attendance was a protective factor. Self-funded HIAs were 21 times more likely to be sexually active [OR = 21.6 (95% CI: 2.3 - 179), p = 0.004]. Conclusion: More than a third of HIV-infected adolescents were sexually active and risky sexual practices were not negligible. 展开更多

Objective: The aim of the present study was to investigate the psychic repercussions of sexual assault among female students in Parakou in 2023. Methods: Descriptive cross-sectional study conducted from December 2022 to July 2023 among all students at the University of Parakou. The sampling technique was stratified non-proportional at two levels. The dependent variable was self-reported sexual assault. The psychopathological repercussions linked to sexual assault and explored in these students were: post-traumatic stress disorder assessed with the Post Traumatic Stress Disorder Checklist-5 (PCL-5) scale;and current depression screened with the Patient Health Questionnaire-9 (PHQ-9) scale. Results: A total of 376 female students from the University of Parakou meeting the inclusion criteria were surveyed. The average age of the subjects surveyed was 20.56 ± 2.46 years, with extremes of 16 and 32 years. A predominance of subjects under 25 was observed. The prevalence of sexual assault among female students at the University of Parakou was 10.63%. The types of aggression suffered were mostly rape (18 people;45%) and sexual touching (16 people;40%), and the aggressors were mainly friends/boyfriends (13;32.5%), family members (12;30.0%) and people from the house/neighborhood (9;22.5%). Psychological repercussions included depression in 72.5% (29) of cases, with mild depression in 30% (12), moderate depression in 37.5% (15) and severe depression in 5% (2). Anxiety disorders were present in 27.50% (11) of victims. The risk factors associated with sexual assault in these students were gravidity (p = 0.014;OR = 15.32), unhappy life events (p = 0.01;OR = 17.24), and age of first sexual intercourse (p = 0.016;OR = 4.608). Conclusion: One in ten female students in Parakou has been sexually assaulted. Once again, preventive action through effective sex education is a means of fighting the problem that should be prioritized for every girl and boy from an early age. Psychological support by specialists should be offered to any victim discovered without delay. Communication on the subject should be multiplied in all family and academic educational environments, from the lowest to the highest levels. 展开更多

Sex development anomalies represent a group of congenital pathologies in which chromosomal, gonadal and anatomical sex differentiation is atypical. The aim of our study was to use molecular biology techniques to elucidate sex in cases of anomalies of sexual differentiation in Burkina Faso. This cross-sectional study took place from March 2023 to June 2023. Oral and blood samples were collected respectively using sterile swabs and stored on Swab Kits and NUCLEIcardTM (https://www.copangroup.com/product-ranges/nucleic-card/) were used to determine gonosome profiles. Extraction was carried out using the DNA Swap solution Kit and the DNA IQ System Kit, and a PowerPlex? 21 kit (Promega) for amplification. The Applied Biosystems 9700 thermal cycler was used for PCR followed by 36 cm capillary electrophoresis in the Applied Biosystems 3130 prism sequencer. Sequence files were analyzed using GeneMapper IDX v. 3.2 software. Seven (07) patients were registered during the study period. There were 4 cases of XX DSD or 46, XX DSD and 3 cases of XY DSD or 46, XY DSD. The median age of our patients was 16 years. Civilian sex was male in 4 cases and female in 3. The most frequent reason for consultation was micropenis in 3 cases, followed by primary amenorrhea and sex ambiguity. There were 03 cases of discrepancy between genetic sex and civil sex. The accessibility of molecular diagnosis is little known to clinicians. XX DSDs or 46, XX DSDs were the most frequent (4/7) in our study. The problem facing this situation is early diagnosis to help prevent complications in Burkina Faso. 展开更多

The mu oil tree(Vernicia montana Lour.) is a dioecious species, but the genetic mechanisms underlying its phenotypic sexual dimorphism are unclear. In this study, we determined two pivotal phases of sex differentiation of mu oil tree via morphological and histological analyses of unisexual flowers:(Ⅰ) differentiation of male or female primordia to produce staminate flowers(SFs) or transient hermaphrodite flowers(HFs),and(Ⅱ) complete abortion of stamens in transient HFs to generate pistillate flowers(PFs). A total of 1621 sex-biased genes were identified by comparative transcriptome analysis which exhibited elevated rates of protein evolution than unbiased genes. The female-biased genes were enriched in the production of defense compounds while male-biased genes were focused on the production of viable pollens. Transcriptomebased analysis revealed that the differentially expressed genes(DEGs) between PFs and SFs in phase Ⅰ involved in abscisic acid(ABA), auxin(AUX), cytokinin(CK), ethylene(ET), and gibberellin(GA) biosynthesis and signaling showed higher expression levels in males than in females in general, whereas the DEGs involved in jasmonic acid(JA) and salicylic acid(SA) pathways displayed opposite expression patterns. Moreover,differentially expressed endogenous ABA, AUX, GAs, JA, and SA exhibited consistent biased expression patterns with the DEGs by UPLC-MSbased analysis. Exogenous application of an anti-ethylene plant growth regulator could promote the development of stamens in PFs and generated HFs. Comparative transcriptomic and hormonal analyses of PFs and SFs in phase Ⅱ indicated an increase in ET concentration when abortion of stamens in PFs occurred. This study suggested that phytohormones play key roles in sex dimorphism and ET may determine the development of stamens in PFs of mu oil tree, which provides an insight into plant sex differentiation mechanisms. 展开更多

Sexual and reproductive health(SRH)services are crucial for women especially during disasters,to reduce maternal mortality and morbidity from miscarriages,unsafe abortions,and post-abortion complications.This study explored the SRH interventions provided during disaster response.A systematic review was conducted to identify what menstrual regulation(MR),safe abortion(SA),and post-abortion care(PAC)approaches/interventions exist to promote resilience in the health system in disaster settings;what intervention components were most eff ective;and challenges and opportunities to meeting SRH rights.Five electronic databases were searched,resulting in 4194 records.Following the screening process,seven publications were included.The intervention-related information in each publication was assessed based on availability,accessibility,acceptability,and quality.Two SRH approaches/interventions were found.The eff ectiveness of intervention components could not be conducted due to the limited number of relevant studies.Challenges were found at facility and community levels,and opportunities included overcoming them,making MR,SA,and PAC integral to the mitigation phase,and policy change to overcome barriers related to unaff ordability and inaccessibility.Recommendations are provided to encourage research and policy towards improving neglected SRH in disaster settings to realize Sustainable Development Goal 3 and the Global Strategy and Sendai Framework's priority to promote disaster-resilient health systems. 展开更多

Objective:To evaluate and compare the effect of semi-rigid ureterorenoscopy on post-procedural sexual function with three different operating room settings.Methods:In this prospective randomized study,consecutive sexually active patients with normal pre-operative sexual function undergoing uncomplicated semi-rigid ureterorenoscopy for distal ureteric stones were randomized into three groups,with three different operating room settings.Procedure-related anxiety and sexual function were assessed pre-operatively using Amsterdam Preoperative Anxiety and Information Scale and Brief Sexual Function Inventory(in males)and Female Sexual Function Index-6(in females),respectively.All the participants were stented following the procedure,and the stent was removed after 3 weeks.Post-procedural sexual function and general discomfort were assessed and compared between three groups at 1 week,3 weeks,and 12 weeks.The effect of surgery-related anxiety,preoperative sexual function,age,and general discomfort(including stent-related discomfort)on post-procedural sexual function were analyzed using multiple regression analysis.A p-value of less than 0.05 was considered statistically significant.Results:Totally,327 eligible patients were randomized into three groups.The group of patients who underwent the procedural with a screen separating the operating area from the patient vision,while the patient could watch the endoscopy through a separate monitor,had better post-procedural sexual function compared to those who had total vision of the operating area as well as to those whose eyes were blocked.This difference was statistically significant.This post-procedural reduction in sexual function could not be attributed to in situ stent alone.Conclusions:Our study showed that semi-rigid ureterorenoscopy can have significant negative effect on sexual function,which can be reduced with proper preoperative counseling and an ideal operating room settings. 展开更多

At the legislative level in China,there has been insufficient theoretical preparation to explicitly include“sexual autonomy”within the scope of general personality rights.In handling the increasing number of disputes related to violations of“sexual autonomy,”judicial biases have emerged during the trial process when courts determine the attribute of the right to“sexual autonomy.”This situation necessitates a clear legal analysis of the concept and attributes of“sexual autonomy”to establish its essential attribute as a personality right,and,from the perspective of legal doctrine,enable the justification of the right to“sexual autonomy”as either a general personality right or other personality interests,thereby providing theoretical support for courts to“adjudicate according to law.”By delineating and categorizing instances of violations of“sexual autonomy,”the constitutive elements and fundamental characteristics of such violations can be clarified.By examining the legal norms governing civil litigation and civil litigation associated with criminal cases concerning violations of“sexual autonomy,”the responsibility determination,remedies,and existing regulatory loopholes regarding violations of“sexual autonomy,”especially in cases involving both criminal and civil matters,can be defined.Based on this foundation,the legal basis,determination mechanism,and compensation standards for claiming compensation for mental damages resulting from violations of“sexual autonomy”can be elucidated. 展开更多

To promote behavioral change among adolescents in Zambia, the National HIV/AIDS/STI/TB Council, in collaboration with UNICEF, developed the Zambia U-Report platform. This platform provides young people with improved access to information on various Sexual Reproductive Health topics through Short Messaging Service (SMS) messages. Over the years, the platform has accumulated millions of incoming and outgoing messages, which need to be categorized into key thematic areas for better tracking of sexual reproductive health knowledge gaps among young people. The current manual categorization process of these text messages is inefficient and time-consuming and this study aims to automate the process for improved analysis using text-mining techniques. Firstly, the study investigates the current text message categorization process and identifies a list of categories adopted by counselors over time which are then used to build and train a categorization model. Secondly, the study presents a proof of concept tool that automates the categorization of U-report messages into key thematic areas using the developed categorization model. Finally, it compares the performance and effectiveness of the developed proof of concept tool against the manual system. The study used a dataset comprising 206,625 text messages. The current process would take roughly 2.82 years to categorise this dataset whereas the trained SVM model would require only 6.4 minutes while achieving an accuracy of 70.4% demonstrating that the automated method is significantly faster, more scalable, and consistent when compared to the current manual categorization. These advantages make the SVM model a more efficient and effective tool for categorizing large unstructured text datasets. These results and the proof-of-concept tool developed demonstrate the potential for enhancing the efficiency and accuracy of message categorization on the Zambia U-report platform and other similar text messages-based platforms. 展开更多

Advancing the application of safety and health(S&H)technologies is likely to remain a value in the mining industry.However,any information that technologies generate must be translated from the organization to the workforce in a targeted way to result in sustainable change.Using a case study approach with continuous personal dust monitors(CPDMs),this paper argues for an organizational focus on technology integration.Although CPDMs provide mineworkers with near real-time feedback about their respirable coal dust exposure,they do not ensure that workers or the organization will continuously use the information to learn about and reduce exposure sources.This study used self-determination theory(SDT)to help three mines manage and communicate about information learned from the CPDM technology.Specifically,35 mineworkers participated in two mixed-method data collection efforts to discuss why they do or do not use CPDMs to engage in dust-reducing practices.Subsequently,the data was analyzed to better understand how organizations can improve the integration of technology through their management systems.Results indicate that using the CPDM to reduce sources of dust exposure is consistent with mineworkers’self-values to protect their health and not necessarily because of compliance to a manager or mine. 展开更多

There are five changes in higher education across the world in the 21st century. The five changes include changes in the university students, changes in the professoriate, changes in academic administration, intemationalisation, and assessment of academic work. These changes are evident in higher education in China. The pressure of the changes -on lecturers will have effects on the wellbeing of lecturers. The study discusses the wellbeing under the Self-determination Theory. This theory views wellbeing as a state of happiness. This theory also proposes that people's intrinsic goals like personal growth, meaningful relationships, and community contributions can enhance the satisfaction of three basic needs--need for autonomy, need for competence, and need for relatedness. In this way, lecturers can experience a sense of wellbeing. The findings of the study are significant for leaders in higher education who need to implement policies that foster effective work environments. 展开更多

Sexual dimorphism between males and females is a common pattern observed in the natural world and has become one of the main focuses of evolutionary biology.Amphibian head size and shape are important factors that may influence food acquisition,but knowledge about the sexual differences between amphibian head size and shape is relatively scant.Here,intersexual differences in the head size and shape of Rana kukunoris,which is a high-elevation frog from the Qinghai-Tibet Plateau,were investigated.Significant differences were found in the head shape but not the head size between sexes.A significant correlation was also observed between prey size and head size.However,these correlations disappeared when individual body size was controlled,suggesting that body size but not food size was the main factor resulting in intersexual differences in head size/shape.The results suggested that food competition between sexes did not result in sexual dimorphism of head shape among these frogs. 展开更多

This quantitative-oriented study investigates junior middle school EFL teachers’beliefs about motivational practices in the language teaching process.Grounded in self-determination theory,the study examined teachers’beliefs in three basic psychological needs(relatedness,competence and autonomy)and the effect of their teaching experience on these beliefs.Data were obtained from 84 Chinese junior middle school English teachers through a questionnaire.Results suggested that teachers recognized motivational practices for relatedness and competence satisfaction while showing relatively low recognition of a few motivating practices for autonomy satisfaction.Teaching experience was found to have no influence on teachers’conception of needs-related motivational practices.Findings reveal that traditional activities like collective lesson preparations may have a negative influence on teachers’beliefs about motivational practices.They also present the necessity for adjustments on educational regulations,and for modern professional training to help teachers understand students’basic psychological needs,and to encourage new ideas to bolster students’intrinsic motivation for language learning. 展开更多

We collected 75 adult Tonkin forest skinks(Sphenomorphus tonkinensis) from Hainan, South China and incubated eggs at four constant temperatures ranging from 22 ℃ to 28 ℃ to study sexual dimorphism, female reproductive characteristics and embryonic thermosensitivity. The largest male was 53.4 mm snout-vent length(SVL), and the largest female was 54.3 mm SVL. The mean SVL was slightly greater in adult females(49.9 mm) than in adult males(48.8 mm), but the difference was not significant.Head length, head width, fore-limb length and hindlimb length were longer in adult males and abdomen length was longer in adult females after accounting for SVL. Accordingly, we conclude that S. tonkinensis is basically a sexually size-monomorphic species with sexual dimorphism in head size, abdomen(trunk)length and limb size. Females laid up to two clutches of 1–4 eggs each per egg-laying season from February to May. Egg mass, clutch size and clutch mass were independent of female SVL. Embryonic stages at laying varied from Dufaure and Hubert’s stage 30 to 31. With female SVL held constant, the negative correlation between egg mass and clutch size was not significant, suggesting that the offspring(egg) sizenumber trade-off between is not evident or eggs are well optimized for size in S. tonkinensis. None of the eggs at 28 ℃ hatched;hatching success was lower at 22 ℃ than at 24 ℃ or 26 ℃. The mean incubation length was 52.9 d at 22 ℃, 40.4 d at 24 ℃ and 33.6 d at 26 ℃. Hatchlings from eggs incubated at 22 ℃,24 ℃ and 26 ℃ did not differ morphologically at hatching, suggesting that temperatures within this range do not differentially affect hatchling morphology in S. tonkinensis. 展开更多

Introduction: This study identifies and analyzes the levels of relations between decision-making competency, self-determination, and health lifestyle in nursing students. Methods: This study was designed as a descriptive research to identify the relations of nursing students’ decision-making competency, self-determination, and health lifestyle. The subjects were 187 nursing students. Data were collected using a structured questionnaire and were analyzed by the IBM SPSS Statistics 19 program. Results: Decision-making competency of nursing students was 3.38 ± 0.41 points, and self-determination was 3.07 ± 0.38 points. Stress and physical exercise were the general and health-related lifestyle factors that contributed to the differences in decision-making competency. There were no differences in self-determination according to these factors. Conclusion: The results of the study showed that the levels of decision-making competency and self-determination in nursing students were moderate. Further studies are recommended for the development of these core abilities in nursing students. 展开更多

Deci and Ryan's (1985a) self-determination theory is on this basis that the promotion of rrtore effective learning is achieved when the learner is intrinsically motivated in an autonomy-supportive climate. In educational settings, the concept of autonomy support, as described in self-determination theory (Deci & Ryan, 1985a), means that the teacher takes the learners' perspective, acknowledges their feelings, and provides them with relevant information and opportunities for choice, while reducing the use of pressure. Therefore, self-determination theory suggests a unique view for understating how autonomy supportive climate can promote intrinsic/autonomous motivation through supporting the basic psychological needs for autonomy, competence, and relatedness. This study first presents an overview of Deci and Ryan's (1985a) self-determination theory and its application to the study of L2 (second language) intrinsic/autonomous motivation. Then, based on the tenets of self-determination theory, this study posits that the more the learners' needs for autonomy, competence, and relatedness are satisfied in the classroom, the more they indicate intrinsic reasons for learning the language. The results o f this review support the fact that intrinsic/extrinsic paradigm, as described in self-determination theory is useful for enhancing L2 learners' autonomous motivation. Finally, 1:his study suggests that self-determination theory has strong implications in L2 learning as the more internalized the reason for L2 learning, the more self-determined and intrinsically/autonomously motiwtted the learners will be 展开更多
