Prevalence of sexually transmitted infections in women of the Czech Republic Armed Forces: a cross-sectional pilot study

IntroductionSexually transmitted infections (STIs) are an everlasting health issue globally. The military environment is recognised as a high-risk setting. Human papillomavirus (HPV), Chlamydia trachomatis and Neisseria gonorrhoeae are the most...

Factors associated with Cryptosporidium in men who have sex with men: A systematic review.

Cryptosporidium parasites are an important cause of diarrhoea globally and sexual transmission may occur in men who have sex with men (MSM). We aimed to systematically review the literature to explore any factors associated with transmission of Cryptosporidium in MSM to provide insight for future guidelines and public health strategies. We searched MEDLINE, Embase, CINAHL and Web of Science for manuscripts published up to July 2023. A primary author conducted an initial screen of abstracts and full text eligibility, and risk of bias was assessed independently by two authors using the Joanna Briggs Institute critical appraisal tools. We used the nine-point synthesis without meta-analysis method to synthesise narrative data. The review was registered on PROSPERO (CRD42023374279). Six manuscripts were included in the final review from the USA (n = 3), Europe (n = 1) and Australia (n = 2) and were case series (n = 2), cross sectional (n = 2) and case control studies (n = 2) published between 1984 and 2021 and overall there were 1582 cases of Cryptosporidium in MSM. We identified demographic factors (living with HIV, younger age [<30years old], geographical areas [Southern Europe v Northern Europe], previous Treponema pallidum, previous Entamoeba histolytica) and behavioural factors (recreational drug use, higher number of sexual partners and MSM attending sex on premises venues with spa/sauna) associated with Cryptosporidium in MSM. Despite a small number of manuscripts in this review, we identified demographic and behavioural factors associated with Cryptosporidium in MSM. These data will provide insight for public health interventions for future outbreaks of Cryptosporidium in MSM.

Cost-effectiveness of 4CMenB vaccination against gonorrhea: importance of dosing schedule, vaccine sentiment, targeting strategy, and duration of protection.

Observational evidence suggests the 4CMenB meningococcal vaccine may partially protect against gonorrhea, with one dose being two-thirds as protective as two. We examined the cost-effectiveness of vaccinating men-who-have-sex-with-men (MSM) in England, with one- or two-dose primary vaccination. Integrated transmission-dynamic health-economic modeling explored the effects of targeting strategy, first- and second-dose uptake levels, and duration of vaccine protection, using observational estimates of vaccine protection. Vaccination with one or two primary doses is always cost-saving, irrespective of uptake, although vaccine sentiment is an important determinant of impact and cost-effectiveness. The most impactful and cost-effective targeting is offering "Vaccination-according-to-Risk" (VaR), to all patients with gonorrhea plus those reporting high numbers of sexual partners. If VaR is not feasible to implement then the more-restrictive strategy of "Vaccination-on-Diagnosis" (VoD) with gonorrhea is cost-effective, but much less impactful. Under conservative assumptions, VaR(2-dose) saves £7.62M(95%CrI:1.15-17.52) and gains 81.41(28.67-164.23) QALYs over 10 years; VoD(2-dose) saves £3.40M(0.48-7.71) and gains 41.26(17.52-78.25) QALYs versus no vaccination. Optimistic versus pessimistic vaccine-sentiment assumptions increase net benefits by ∼30%(VoD) or ∼60%(VaR). At UK costs, targeted 4CMenB vaccination of MSM gains QALYs and is cost-saving at any uptake level. Promoting uptake maximizes benefits and is an important role for behavioral science.

Sexual history of patients with human papillomavirus positive and negative oropharyngeal cancer: A systematic review and meta-analysis.

Increased sexual activity is associated with higher human papillomavirus (HPV) rates; however, there is a lack of analysis comparing the sexual history of patients with HPV positive and HPV negative oropharyngeal cancer (OPC). In this meta-analysis, PubMed, Scopus, and CINAHL were searched for articles that included patients with OPC and reported information regarding HPV status and either history of oral sex, number of sexual partners, or sexually transmitted infections (STI). A total of 11 studies were included with 3296 patients with OPC. Patients with HPV positive OPC were more likely than patients with HPV negative OPC to report a history of oral sex (92%, 95% CI: 87.0-97.0 vs. 74.5%, 95% CI: 50.6-98.4, p < 0.0001), higher mean number of sexual partners (18.4 partners, 95% CI: 1.5-35.4 vs. 7.2 partners, 95% CI: 1.0-13.4, p < 0.0001), and more frequent history of STI (23.7%, 95% CI: 18.4-29.0 vs. 8.8%, 95% CI: 4.7-12.8, p = 0.0001). Compared to patients with HPV negative OPC, our analysis shows a larger proportion of patients with HPV positive OPC had participated in oral sex, had a higher number of sexual partners, and had a higher proportion of STI history.

Impact of enacted stigma on mental health, substance use, and HIV-related behaviors among sexual minority men in Zambia

Sexual minority men (SMM) in Zambia face significant challenges including stigma, discrimination, and mental health issues, which further impact their HIV-related risk behaviors. This study aimed to investigate the associations between enacted stigma, substance abuse, HIV-related behaviors, and mental health (i.e., depression, anxiety, and post-traumatic stress disorder [PTSD] symptoms) among SMM in Zambia. SMM aged 18–35 years who reported having multiple and/or concurrent sexual partners or low and/or inconsistent condom use in the past three months were recruited from four districts in Zambia between February and November 2021. Participants completed an anonymous interviewer-administered survey. Key variables of interest were compared between participants with higher vs. lower levels of enacted stigma. Independent samples t-tests were used for continuous variables, and chi-squared tests were used for categorical variables. A total of 197 eligible SMM participated in the study (mean age = 24.41 years). Participants with a higher level of enacted stigma showed a higher level of anxiety symptoms (χ2 = 12.91, p ≤ .001), PTSD symptoms (χ2 = 7.13, p < .01), tobacco use (χ2 = 10.47, p < .01), cannabis use (χ2 = 5.90, p < .05), and a higher number of sexual partners (t = 1.99, p < .05) in the past three months. Stigma reduction interventions may help mitigate substance abuse, HIV-related behaviors, and adverse mental health outcomes among SMM in Zambia. Health care providers, especially psychiatric-mental health nurses, can incorporate strategies for recognizing and addressing stigma into their practice through training and integrate multiple resources to create an inclusive and non-judgmental environment for SMM to improve their well-being.

Moderating Effect of Gender on the Relationship Between Sexual Knowledge and Sexual Activity Among Adolescents

IntroductionAdolescent sexual activity is an important topic for public health policies and can be shaped by them. This study examines the relationship between sexual knowledge and sexual activity and tests the moderating effect of gender.MethodsThis study uses a random sample of 1246 Polish adolescents aged 18−19 years. The methods of partial least squares path modeling and bootstrap testing are utilized.ResultsAmong boys, unlike among girls, a low level of sexual knowledge was associated with early and intense sexual activity represented by an early age of sexual initiation, a high number of sexual partners, and a short time since last sexual intercourse. Additionally, the average level of sexual knowledge was lower among boys than among girls. More specifically, the difference in knowledge of every element of the male reproductive system between boys and girls was not significant; however, girls were more aware of the female reproductive system than boys.ConclusionsGender differentiated the relationship between sexual knowledge and sexual activity. The revealed moderating effect could reflect gender differences in the motives of sexual activity of adolescent men and women. The early and intense sexual activity exhibited by boys with limited sexual knowledge exposed them to sexually transmitted diseases and unintended parenthood.Policy ImplicationsThe self-selection of boys with low sexual knowledge levels into early and intense sexual activity may be of interest to public health.

Patterns of sexual risk behaviour among young adults

Abstract Background Sexual risk behaviour (SRB), including the subtypes sex without contraception, sexualized substance use, sex work, and intimate partner violence, leads to health-related consequences for one-self or intimate partners. Especially young adults comprise a vulnerable group for SRB as they tend to use risk behaviour as maladaptive coping strategies to face developmental challenges. We aim to identify SRB patterns by analysing the relation between SRB-subtypes and to previous found risk factors, and to derive adequate treatment and prevention strategies. Methods A cross-sectional study was conducted via an online-questionnaire. SRB was measured via nine items. Latent class analysis was used to identify patterns of SRB, multinomial logistic regression to capture related risk factors. Included risk factors were gender, sexual orientation, younger age of first intercourse, higher number of sexual partners, and hypersexual behaviour (HB; measured via HB-inventory). Results Within the sample (n = 609) three classes of SRB patterns were identified: unremarkable (67%; low values in all SRB facets), and the therapeutic-relevant classes shame-ridden (17%; esp. high values in sexual feelings of shame/ guilt), and risky (16%; high values in all SRB facets, esp. sexualized use of illegal drugs, inadequate contraception use, and impairments in important relationships). Both pathological patterns are strongly associated to higher HB-values. Male and queer participants tend to demonstrate pathological SRB-patterns more often than females and heterosexuals. Conclusions To implement adequate gender- and diversity sensitive prevention and treatment addressing SRB it is necessary to understand the complexity of its expression. Based on the results, shame-ridden clients could be addressed by focusing on their feelings of shame/ guilt, while it seems helpful to address substance use and compulsive sexual behaviour of clients belonging to the risky group primarily. Key messages • Three patterns of sexual risk behaviour could be identified, two of them are theraptuic-relevant. • To implement adequate SRB prevention and treatment it is necessary to understand its complexity, thus respective differentiated strategies should address specific needs of young adults.

The sins of the church: The long-term impacts of Christian missionary praxis on HIV and sexual behaviour in Zambia

ABSTRACT This study examines the long-term effect of Christian missionary exposure on HIV infection and related sexual behaviour in Zambia. I use distance to a historical missionary church and health facility as proxies for missionary exposure. I constructed a geocoded data set combining information on the historical locations of churches and missionary health centres with contemporary individual-level data. I find that individuals who live close to a historical missionary church have a higher likelihood of being infected with HIV. I find no significant effect of proximity to a missionary health centre on HIV. Considering that heterosexual transmission is the main channel of HIV transmission in Zambia, I analyse the effect of missionary exposure on sexual behaviour. The following patterns emerge: individuals who live close to a Protestant church are less likely to engage in premarital sexual abstinence; they also have their first sexual encounter at an earlier age, with the effect being stronger for men than women. Living near a Catholic church is associated with having a higher number of sexual partners.

Risk Factors for Patients with Hepatitis B and C in Hemodialysis Unit

Background: Risk factors for HCV, HBV transmission are blood transfusions and surgeries before 1992, intravenous drug use, contaminated parenteral drugs and other invasive non-medical procedures (tattooing, piercing). Based on these risk factors, high-risk groups are: multiramified patients (i.e., hemophiliacs), health personnel, intravenous drug users, inmates, individuals with high-risk sexual behaviors (early sex life, high number of sexual partners and prostitution). Other populations at risk are patients on extracorporeal circulation system, such as end-stage kidney disease patients on hemodialysis program. Study aim: To determine risk factors for patients with hepatitis B and C in hemodialysis unit. Methodology: A descriptive study design was conducted at Al-Najaf city in the southern region of Iraq in Al-Sadder Medical City and Al-Hakim General Hospital from February 20th, 2023, to May 23th, 2023, in order to assess risk factors for patients with hepatitis B and C in hemodialysis unit. The methodological strategies for data collection used an assessment questionnaire survey. Results: As the study shows, that the risk factors that cause the most infection are hemodialysis sessions, contact with infected persons, and injected medication, while the lowest risk factors to spread infection are children born with infected hepatitis and unprotected sexual contacted. Conclusion: The study concludes that the first leading risk factor for infection is the hemodialysis session, while the contact with infected persons and contaminated injections of medication comes in the second place. Recommendations: Careful monitoring and strict adherence to infection control procedures among patients undergoing hemodialysis treatment, including commitment to sterilization of hemodialysis devices and the use of all preventive measures when starting the hemodialysis procedure.

Prevalence, Risk factors, and Shedding of Human Herpes Virus-8 among Men Having Sex With Men Enrolled in a Pre-exposure Prophylaxis Study.

Seroprevalence and risk factors for Human Herpesvirus-8 (HHV-8) infection among HIV-negative men who have sex with men (MSM) on pre-exposure prophylaxis (PrEP) have not been well characterized. Our objectives were to assess the prevalence and incidence of HHV-8 infection in MSM enrolled on PrEP and assess viral shedding in seropositive participants. The ANRS IPERGAY study enrolled 429 participants in France and Canada to evaluate oral PrEP for HIV-1 prevention. Stored sera samples at day 0 (D0) and last visit were tested for the detection of HHV-8 antibodies using an indirect immunofluorescence assay. Baseline characteristics were analyzed to identify risk factors associated with HHV-8 seropositivity. Among seropositive participants, HHV-8 DNA was quantified on available oral and anal swabs, and ORF-K1 typing performed on HHV-8 positive samples. One hundred participants were seropositive at D0 (prevalence of 24%, 95% Confidence Interval (95%CI): 20·0-28·4) and 18/329 seroconverted during the study (incidence rate of 2·66 per 100 person-years, 95%CI: 1·57-4·20). Risk factors independently associated with baseline HHV-8 seropositivity included older age, high number of sexual partners, chemsex use and HSV-2 seropositivity. Among HHV-8 seropositive participants with available swab(s) for virological analysis, 37/115 (32%) displayed HHV-8 oral shedding, and 5/113 (4.4%) anal shedding at least once. Four patients had positive viral load before seroconversion. Prevalence and incidence of HHV-8 infection were high in HIV-negative PrEP users. Among seropositive participants, HHV-8 DNA is mainly detected in saliva, which may play a major role in viral transmission in this population.

Non-Consensual Sex and Help-Seeking Behavior Among PrEP Users in Belgium: Findings from an Online Survey

ABSTRACT Non-consensual sex poses a threat not only to sexual health but also to mental and physical health in general. HIV pre-exposure prophylaxis (PrEP) users might be particularly vulnerable to non-consensual sex because of interplaying factors such as mental health disorders, a high number of sex partners, engagement in chemsex, and the widespread use of dating apps. The objectives of this study were to assess the occurrence of non-consensual sex, its associated factors, and related help-seeking behavior among PrEP users. We analyzed data from an online survey among PrEP users in Belgium (09/2020-02/2022). Almost one in five participants (34/187, 18.2%) reported having ever experienced non-consensual sex. The most reported form was having sex against one’s will, followed by having been given drugs against one’s will, and having had sex without a condom against one’s will. The vast majority of those who had experienced non-consensual sex (29/34, 85.3%) did not seek help afterward, mostly due to a lack of perceived need (21/29, 72.4%). Reported barriers to seeking help were shame (6/29, 20.7%) and lack of awareness of help services (3/29, 10.3%). Having experienced non-consensual sex in the past five years was associated with younger age and suicidal ideation in a multivariable logistic regression model. We conclude that addressing barriers to non-consensual sex help services is crucial to maximize their use and minimize the consequences of non-consensual sex experiences. PrEP consultations also represent an opportunity to offer such help given PrEP users are already familiar with these PrEP services and engaged in care.

The Use of Daily and On-Demand Oral Pre-Exposure Prophylaxis Dosing Strategies Among Young Adult Gay, Bisexual and Other Men who have Sex with Men Enrolled in an mHealth Adherence Intervention.

Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention option for gay, bisexual and other men who have sex with men (GBMSM). However, with newer PrEP options, a greater understanding of whether and why GBMSM switch dosing strategies is needed to inform clinical practice and research. We assessed the dosing strategies (daily or on-demand) of GBMSM enrolled in an mHealth PrEP adherence pilot intervention at four timepoints over approximately 10 months. Among GBMSM with complete data (n = 66), a consistent daily dosing strategy was used by most (73%) participants across all time points, while on-demand PrEP was used at least once during the study period by 27% of participants. A higher percentage of on-demand PrEP users self-reported as Asian/Pacific Islander and had less positive attitudes toward PrEP, adjusting for key sociodemographic variables and intervention arm. Daily PrEP users reported high numbers of sexual partners, and the primary reason that they would switch to on-demand PrEP is reduced sexual activity. At the final assessment, 75% of participants were taking daily PrEP, of whom 27% reported that they would like to switch to another option, including on-demand and long-acting injectable PrEP. While findings were largely descriptive, they showed that switches in PrEP dosing strategies are relatively common and PrEP strategy choice may vary across racial and ethnic groups.

Sexual Risk Behavior of Children and Adolescents With a History of Sexual Violence

Abstract: Theoretical Background: Experiencing sexual violence (SV) at a young age can impede sexual development and lead to sexual risk behavior. Objective: This meta-analysis aims to provide a systematic overview regarding the development of sexual risk behavior in sexually violated children and adolescents. Method: A systematic literature search was carried out (PubMed, ERIC, Cochrane, and PubPsych). Meta-analyses were conducted, investigating the link between child SV and sexual behaviors (teenage pregnancy, safer sex, substance use during intercourse, transactional sex, and number of sex partners). Results: A total of 19 studies were identified. Survivors of SV are more likely to have higher numbers of sex partners, be involved in teenage pregnancy, and participate in transactional sex. Discussion: Early identification of sexually violated youth is important in order to intervene at an early stage and reduce the effects of sexual violence preventively.

The Correlation of Papanicolaou Smears and Clinical Features to Identify the Common Risk Factors for Cervical Cancer: A Retrospective and Descriptive Study from a Tertiary Care Hospital in Trinidad.

Background: Cervical cancer, the fourth most frequent cancer in women, is associated with the human papillomavirus (HPV). This study identifies risk factors and clinical findings for abnormal cervical cytology and histopathology in the Trinidad and Tobago populations. Some risk factors include early age of first coitus, a high number of sexual partners, high parity, smoking, and using certain medications, such as oral contraception. This study aims to identify the significance of Papanicolaou (pap) smears and the common risk factors that contribute to the development of premalignant and malignant cervical lesions. Method: A three-year retrospective, descriptive study of cervical cancer was conducted at the Eric Williams Medical Sciences Complex. The subject population included 215 female patients aged 18 years and older with the following documented abnormal cervical cytology: (ASCUS), ASC-H, LSIL, HSIL, Atypical Glandular cells, HPV, Adenocarcinoma, and Invasive Squamous Cell Carcinoma. Histopathology records were analysed for thirty-three of these patients. Patients' information was recorded on data collection sheets adapted from the North Central Regional Health Authority's cytology laboratory standardised reporting format request form. Results and Findings: The data were analysed via Statistical Package for Social Sciences (SPSS) software edition 23 using frequency tables and descriptive analysis. The mean sample age of the population was 36.7 years, the first age of coitus was 18.1 years, the number of sexual partners was 3.8, and the number of live births was 2. LSIL was the most popular abnormal finding, 32.6%, followed by HSIL, 28.8%, and ASCUS, 27.4%. Most histopathological reports resulted in CIN I and II. Conclusions: The significant risk factors observed for cytology abnormalities and premalignant lesions were early age of coitus, a high number of sexual partners, and no use of contraception. Patients mostly presented as asymptomatic despite obtaining abnormal cytology results. Hence, regular pap smear screening should continue to be highly encouraged.

Psychiatric symptoms in people living with HIV: prevalences, interactions and consequences

IntroductionPeople living with HIV (PLHIV) experience higher levels of mental health issues compared to the general population. Especially depression, anxiety, impulsivity and substance use occur frequently in PLHIV. This is thought to have important consequences for quality of life, sexual risk behaviour and antiretroviral treatment (ART) adherence. Both in PLHIV as well as in the general population, divergent psychiatric symptoms often co-occur, and influence one another.ObjectivesTo assess the interrelatedness of psychiatric symptoms and their potential consequences in PLHIV.MethodsData from 1615 outpatient PLHIV using suppressive ART from the 2000HIV study (NCT03994835) were analysed. Participants reported on the severity of substance use (MATE-Q), depression and anxiety (HADS), impulsivity (BIS-11), quality of life (EQ-5D-5L), ART adherence (MASS-8) and sexual risk behaviour. For these variables, prevalence rates and mean scores were calculated. After binarizing the data, an Ising network model was constructed. Using this network, interrelations between psychiatric symptoms were assessed, the centrality of symptoms was estimated and connections with clinical consequences were explored.ResultsIn our cohort of PLHIV, the increased prevalence of substance use was most pronounced, as shown by a prevalence rate of 28.7% for smoking, 13.6% for cannabis use, 11.1% for heavy alcohol drinking and 9.2% for ecstasy use in the past month. The network analysis revealed that symptoms of depression and anxiety were most strongly interrelated. The depressive symptom “feeling slowed down” was one of the most central symptoms, and was most strongly connected with quality of life. Substance use was associated with a higher occurrence of sexually transmitted diseases, and this relationship was mediated by a higher number of sexual partners. Notably, ART adherence did not display any connections with depression, anxiety, impulsivity or substance use.Image:ConclusionsThe high occurrence of substance use and its link with sexual risk behaviour, emphasizes it’s role as a potential target for prevention of HIV transmission. Contrary to general assumption, psychiatric symptoms are not associated with lower levels of ART adherence in our cohort. Treatment of depression in PLHIV might be improved by focussing on the symptom of feeling slowed down, since this symptom was most strongly connected with quality of life.Disclosure of InterestE.

Determinants and prediction of Chlamydia trachomatis re-testing and re-infection within 1 year among heterosexuals with chlamydia attending a sexual health clinic.

Chlamydia trachomatis (chlamydia) is one of the most common sexually transmitted infections (STI) globally, and re-infections are common. Current Australian guidelines recommend re-testing for chlamydia 3 months after treatment to identify possible re-infection. Patient-delivered partner therapy (PDPT) has been proposed to control chlamydia re-infection among heterosexuals. We aimed to identify determinants and the prediction of chlamydia re-testing and re-infection within 1 year among heterosexuals with chlamydia to identify potential PDPT candidates. Our baseline data included 5,806 heterosexuals with chlamydia aged ≥18 years and 2,070 re-tested for chlamydia within 1 year of their chlamydia diagnosis at the Melbourne Sexual Health Center from January 2, 2015, to May 15, 2020. We used routinely collected electronic health record (EHR) variables and machine-learning models to predict chlamydia re-testing and re-infection events. We also used logistic regression to investigate factors associated with chlamydia re-testing and re-infection. About 2,070 (36%) of 5,806 heterosexuals with chlamydia were re-tested for chlamydia within 1 year. Among those retested, 307 (15%) were re-infected. Multivariable logistic regression analysis showed that older age (≥35 years old), female, living with HIV, being a current sex worker, patient-delivered partner therapy users, and higher numbers of sex partners were associated with an increased chlamydia re-testing within 1 year. Multivariable logistic regression analysis also showed that younger age (18-24 years), male gender, and living with HIV were associated with an increased chlamydia re-infection within 1 year. The XGBoost model was the best model for predicting chlamydia re-testing and re-infection within 1 year among heterosexuals with chlamydia; however, machine learning approaches and these self-reported answers from clients did not provide a good predictive value (AUC < 60.0%). The low rate of chlamydia re-testing and high rate of chlamydia re-infection among heterosexuals with chlamydia highlights the need for further interventions. Better targeting of individuals more likely to be re-infected is needed to optimize the provision of PDPT and encourage the test of re-infection at 3 months.

Infecção cervical por papilomavírus humano em mulheres idosas

Abstract Objective To investigate the presence of cervical infection by human papillomavirus (HPV) and associated factors in older women Method A cross-sectional, retrospective descriptive study with a quantitative approach was conducted. The sample comprised 106 women aged 60 years or over, seen at public health services of a city in southern Brazil, who underwent cervical cell collection for cytological analysis and molecular detection of HPV DNA. Clinical and sociodemographic data were collected using a standardized questionnaire and from Pap test result Results Patient age was 60-82 years, with a mean of 64.9 ± 5.1 years. HPV was detected in 14 (13.2%) of the study participants and 8 viral types were identified, the majority (n=7; 87.5%) of high oncogenic risk. Chi-square analysis revealed that positive HPV cases were associated with a higher number of sexual partners (p= 0.018). On cytology, most of the women (n=102; 96.2%) had a negative result for intraepithelial lesion or malignancy, and two (1.8%) had abnormal cytology, but neither were positive for HPV infection on molecular testing. Of the 10 women evaluated at two visits, seven (70%) tested negative for HPV infection on both evaluations, two (20%) eliminated the HPV infection, and one (10%) showed conversion to positive infection status. None of the cases had persistent infection. Conclusion Older women are susceptible to HPV infection and to the lesions caused by the virus. This group should therefore continue regular cytological screening.

Prevalence of HPV infection and cervical intraepithelial lesions in HIV positive and negative women in the city of Florianopolis

Introduction: The human papillomavirus (HPV) is the most common sexually transmitted infection among women. The HPV of high oncogenic risk, associated with other factors, presents a risk of progressing to a precancerous lesion of the uterus and even cancer. Such an evolution is related to the persistence of the infection and other factors, mainly those that interfere with women’s immunity. The immunosuppression caused by HIV infection is an important factor for viral persistence and the onset of these lesions. Objectives: To compare the prevalence of HPV infection and cervical intraepithelial lesions in HIV-positive and negative women and describe the possible associated risk factors. Methods: The sample consisted of 50 HIV positive women (study group) and 50 HIV negative women (control group) recruited from the public health system of Florianópolis from January to April 2022. Cervical samples were collected for cytological analysis and for the detection of high-risk oncogenic HPV DNA by polymerase chain reaction (PCR). Categorical variables were compared using the chi-square test, with a significance level set at 5% Results: HPV infection was more prevalent in the control group; however, HIV positive women presented higher frequency of intraepithelial lesions diagnosed on cytology. Factors such as higher number of sexual partners, depression and smoking were more frequent in the group of HIV positive women. CD4 T cells lower than 200 cells/mm3 was associated with a higher number of altered Pap smears and a positive HPV DNA test. The use of combination antiretroviral therapy and undetectable viral load were associated with more frequent normal cytology and undetected HPV DNA. Conclusion: The prevalence of cervical intraepithelial lesions in HIV-infected women is higher than among women without the infection. The presence of HIV infection was the most important risk factor associated with the development of cervical lesions.

Impulsivity as a Predictor of Early Dating Initiation in 11-12-Year-Old Youth.

As early initiation of dating behaviors is associated with risky sexual behaviors (e.g., higher number of sexual partners, sex with strangers), the current study examined determinants of early dating behaviors, focusing on impulsivity. Participants were 11-12-year-old boys (n = 109) and girls (n = 61) recruited from a psychiatric clinic and ads targeted to the general public. Ordered logistic regression models were used to examine the association between each facet of impulsivity (negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking) and dating behaviors. Youth with higher sensation seeking and negative urgency was more likely to initiate dating behaviors at early ages compared to those with lower scores on those measures. Further, we found that female gender and higher parental education were associated with lower risk of initiating dating behaviors at early age. Advanced pubertal development was associated with higher risk for early dating. Our findings can inform prevention efforts, identifying sensation seeking and negative urgency as predictors of youths' early engagement in dating behaviors, which can be a precursor of early sexual debut and risky sexual behaviors.

Redheaded women are more sexually active than other women, but it is probably due to their suitors.

Women with red hair color, i.e., 1-9% of female Europeans, tend to be the subject of various stereotypes about their sexually liberated behavior. The aim of the present case-control study was to explore whether a connection between red hair color and sexual behavior really exists using data from 110 women (34% redheaded) and 93 men (22% redheaded). Redheadedness in women, correlated with various traits related to sexual life, namely with higher sexual desire as measured by Revised Sociosexual Orientation Inventory, with higher sexual activity and more sexual partners of the preferred gender over the past year, earlier initiation of sexual life, and higher sexual submissiveness. Structural equation modelling, however, showed that sexual desire of redheaded women mediated neither their higher sexual activity nor their higher number of sexual partners. These results indirectly indicate that the apparently more liberated sexual behavior in redheaded women could be the consequence of potential mates' frequent attempts to have sex with them. Our results contradicted the three other tested models, specifically the models based on the assumption of different physiology, faster life history strategy, and altered self-perception of redheaded women induced by stereotypes about them. Naturally, the present study cannot say anything about the validity of other potential models that were not subjects of testing.
