Comparison of T-cell immune responses to SARS-CoV-2 spike (S) and nucleocapsid (N) protein using an in-house flow-cytometric assay in laboratory employees with and without previously confirmed COVID-19 in South Africa: nationwide cross-sectional study.

AIMS: To compare specific T-cell responses between laboratory employees in South Africa with and without previously diagnosed SARS-CoV-2 infection. METHODS: Employees at a private pathology laboratory in South Africa were invited to participate in a nationwide cross-sectional study. T-cell proliferation to SARS-CoV-2 nucleocapsid (N)-proteins and spike (S)-proteins was measured by flow cytometry and compared between participants. RESULTS: Based on classification according to SARS-CoV-2 reverse transcription (RT)-PCR results, a total of 81% (42/52) of positive participants demonstrated T-cell proliferation to SARS-CoV-2 N-proteins or S-proteins (95% CI 67.5% to 90.4%), while 62% (68/110) of negative participants also had detectable T-cell responses to SARS-CoV-2 proteins (95% CI 52.1% to 70.9%). When classified according to SARS-CoV-2 serology results, 92.6% (50/54) of positive participants demonstrated T-cell proliferation to SARS-CoV-2 proteins (95% CI 82.1 to 97,9 %), while 56% (60/108) of negative participants demonstrated T-cell proliferation (95% CI 45.7% to 65.1%). The magnitude of the T-cell responses as determined by a stimulation index, was significantly higher in the group previously infected by SARS-CoV-2 than in the negative group. A statistically significant difference in T-cell proliferation was noted between high risk and low risk groups for exposure to SARS-CoV-2 within the negative group, but no significant difference in magnitude of the response. CONCLUSIONS: A significant proportion of South African laboratory employees who were not previously diagnosed with COVID-19 demonstrated T-cell reactivity to SARS-CoV-2 N-proteins and S-proteins. The pre-existing T-cell proliferation responses may be attributable to cross-reactive immune responses to other human coronaviruses, or possibly asymptomatic infection.

Seroprevalence of Severe Acute Respiratory Syndrome Coronavirus 2 After the Second Wave in South Africa in Human Immunodeficiency Virus-Infected and Uninfected Persons: A Cross-Sectional Household Survey.

BACKGROUND: Seroprevalence studies are important for quantifying the burden of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in resource-constrained countries. METHODS: We conducted a cross-sectional household survey spanning the second pandemic wave (November 2020 to April 2021) in 3 communities. Blood was collected for SARS-CoV-2 antibody (2 enzyme-linked immunosorbent assays targeting spike and nucleocapsid) and human immunodeficiency virus (HIV) testing. An individual was considered seropositive if testing positive on ≥1 assay. Factors associated with infection, and the age-standardized infection case detection rate, infection hospitalization rate, and infection fatality rate were calculated. RESULTS: Overall, 7959 participants were enrolled, with a median age of 34 years and an HIV prevalence of 22.7%. SARS-CoV-2 seroprevalence was 45.2% (95% confidence interval 43.7%-46.7%) and increased from 26.9% among individuals enrolled in December 2020 to 47.1% among those enrolled in April 2021. On multivariable analysis, seropositivity was associated with age, sex, race, being overweight/obese, having respiratory symptoms, and low socioeconomic status. Persons living with HIV with high viral load were less likely to be seropositive than HIV-uninfected individuals. The site-specific infection case detection rate, infection hospitalization rate, and infection fatality rate ranged across sites from 4.4% to 8.2%, 1.2% to 2.5%, and 0.3% to 0.6%, respectively. CONCLUSIONS: South Africa has experienced a large burden of SARS-CoV-2 infections, with <10% of infections diagnosed. Lower seroprevalence among persons living with HIV who are not virally suppressed, likely as a result of inadequate antibody production, highlights the need to prioritize this group for intervention.

SARS-CoV-2 Seroprevalence after Third Wave of Infections, South Africa.

By November 2021, after the third wave of severe acute respiratory syndrome coronavirus 2 infections in South Africa, seroprevalence was 60% in a rural community and 70% in an urban community. High seroprevalence before the Omicron variant emerged may have contributed to reduced illness severity observed in the fourth wave.

SARS-CoV-2 Seroprevalence in a Rural and Urban Household Cohort during First and Second Waves of Infections, South Africa, July 2020-March 2021.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections may be underestimated because of limited access to testing. We measured SARS-CoV-2 seroprevalence in South Africa every 2 months during July 2020-March 2021 in randomly selected household cohorts in 2 communities. We compared seroprevalence to reported laboratory-confirmed infections, hospitalizations, and deaths to calculate infection-case, infection-hospitalization, and infection-fatality ratios in 2 waves of infection. Post-second wave seroprevalence ranged from 18% in the rural community children <5 years of age, to 59% in urban community adults 35-59 years of age. The second wave saw a shift in age distribution of case-patients in the urban community (from persons 35-59 years of age to persons at the extremes of age), higher attack rates in the rural community, and a higher infection-fatality ratio in the urban community. Approximately 95% of SARS-CoV-2 infections were not reported to national surveillance.

Virus Etiology, Diversity and Clinical Characteristics in South African Children Hospitalised with Gastroenteritis.

BACKGROUND: Viral gastroenteritis remains a major cause of hospitalisation in young children. This study aimed to determine the distribution and diversity of enteric viruses in children ≤5 years, hospitalised with gastroenteritis at Kalafong Provincial Tertiary Hospital, Pretoria, South Africa, between July 2016 and December 2017. METHODS: Stool specimens (n = 205) were screened for norovirus GI and GII, rotavirus, sapovirus, astrovirus and adenovirus by multiplex RT-PCR. HIV exposure and FUT2 secretor status were evaluated. Secretor status was determined by FUT2 genotyping. RESULTS: At least one gastroenteritis virus was detected in 47% (96/205) of children. Rotavirus predominated (46/205), followed by norovirus (32/205), adenovirus (15/205), sapovirus (9/205) and astrovirus (3/205). Norovirus genotypes GI.3, GII.2, GII.3, GII.4, GII.7, GII.12, GII.21, and rotavirus strains G1P[8], G2P[4], G2P[6], G3P[4], G3P[8], G8P[4], G8P[6], G9P[6], G9P[8] and sapovirus genotypes GI.1, GI.2, GII.1, GII.4, GII.8 were detected; norovirus GII.4[P31] and rotavirus G3P[4] predominated. Asymptomatic norovirus infection (GI.3, GI.7, GII.4, GII.6, GII.13) was detected in 22% of 46 six-week follow up stools. HIV exposure (30%) was not associated with more frequent or severe viral gastroenteritis hospitalisations compared to unexposed children. Rotavirus preferentially infected secretor children (p = 0.143) and norovirus infected 78% secretors and 22% non-secretors. CONCLUSION: Rotavirus was still the leading cause of gastroenteritis hospitalisations, but norovirus caused more severe symptoms.

Dimensions of decision difficulty in women's decision-making about abortion: A mixed methods longitudinal study.

Relatively little is known about the ease or difficulty with which women decide to have an abortion, and most research uses single-item measurements. We used a mixed methods approach to combine data from the Dutch Abortion and Mental Health Study (DAMHS, n = 325) with data from a qualitative study about the decision process with a small subsample (n = 69) of the DAMHS study. We used the findings from the qualitative study to develop the Dimensions of Abortion Decision Difficulty [DADD] scale, and tested this scale among a larger sample of women who took part in the second wave of the cohort study (n = 264). Qualitative analyses revealed six dimensions of decision difficulty. The DADD scale was based on these six dimensions. Results from the DADD scale at follow-up reduced these to four dimensions: (1) unrealistic fears about the abortion and fantasies about the pregnancy; (2) decision conflict; (3) negative abortion attitudes; and (4) general indecisiveness. Decision conflict was the only dimension related to previous mental disorders. The findings suggest that the concept of decision difficulty seems multidimensional, rather than unidimensional. On a clinical level, it could be important to separate the more general fears, attitudes, and indecisiveness from strong decision conflict, because the latter might involve pressure of others, lack of decision ownership, and might be related to previous mental health.

Understanding Decision-Making and Decision Difficulty in Women With an Unintended Pregnancy in the Netherlands.

Previous research indicates that a considerable number of women with an unintended pregnancy experience difficulty deciding about continuing or terminating the pregnancy. We examined the decision-making processes of women who experienced high decision difficulty and women who experienced little decision difficulty, to gain insight in the factors that contribute to experienced decision difficulty. Sixty-nine women who had an abortion, and 40 women who had decided to continue their unintended pregnancy, participated in qualitative interviews. We found that women's decision processes varied on 11 relevant criteria. The decision-making processes of women who experienced little decision difficulty differed from that of women who experienced high decision difficulty, but the decision-making processes of women who carried their pregnancy to term and the high decision difficulty abortion group were strikingly similar. Implications of our findings for future research and for professional care for women who are in need of support during decision-making are discussed.

Effects of Aversive Classical Conditioning on Sexual Response in Women With Dyspareunia and Sexually Functional Controls.

INTRODUCTION: In dyspareunia-a somatically unexplained vulvovaginal pain associated with sexual intercourse-learned pain-related fear and inhibited sexual arousal are supposed to play a pivotal role. Based on research findings indicating that enhanced pain conditioning is involved in the etiology and maintenance of chronic pain, in the present study it was hypothesized that enhanced pain conditioning also might be involved in dyspareunia. AIM: To test whether learned associations between pain and sex negatively affect sexual response; whether women with dyspareunia show stronger aversive learning; and whether psychological distress, pain-related anxiety, vigilance, catastrophizing, and sexual excitation and inhibition were associated with conditioning effects. METHODS: Women with dyspareunia (n = 36) and healthy controls (n = 35) completed a differential conditioning experiment, with one erotic picture (the CS+) paired with a painful unconditional stimulus and one erotic picture never paired with pain (the CS-). MAIN OUTCOME MEASURES: Genital sexual response was measured by vaginal photoplethysmography, and ratings of affective value and sexual arousal in response to the CS+ and CS- were obtained. Psychological distress, pain cognitions, and sexual excitation and inhibition were assessed by validated questionnaires. RESULTS: The two groups showed stronger negative affect and weaker subjective sexual arousal to the CS+ during the extinction phase, but, contrary to expectations, women with dyspareunia showed weaker differential responding. Controls showed more prominent lower genital response to the CS+ during acquisition than women with dyspareunia. In addition, women with dyspareunia showed stronger expectancy for the unconditional stimulus in response to the safe CS-. Higher levels of pain-related fear, pain catastrophizing, and sexual inhibition were associated with weaker differential conditioning effects. CONCLUSIONS: Pairing of sex with pain negatively affects sexual response. The results indicate that a learned association of sex with pain and possibly deficient safety learning play a role in dyspareunia. Both S, Brauer M, Weijenborg P, Laan E.

A Qualitative Study on Experiences After Vulvar Surgery in Women With Lichen Sclerosus and Sexual Pain.

INTRODUCTION: Lichen sclerosus (LS) of the vulva can profoundly affect sexual interaction because of painful fissures and narrowing of the vaginal introitus. Successful surgical treatment is usually defined as restoration of (pain-free) penetrative sexual activity. AIMS: To evaluate the impact of surgery on (dyadic) sexual functioning and pleasure and psychological well-being. METHODS: Nineteen women with anogenital LS participated in audiotaped, qualitative, individual interviews after surgery to re-enable sexual intercourse. MAIN OUTCOME MEASURES: Physical, sexual, and psychological experiences were analyzed using the constant comparative method. RESULTS: Vulvar surgery resulted in a decrease of sexual pain in 13 of 19 patients (68%). Of these 13 patients, 4 were completely free of pain and the other 9 patients expressed a shift from preoperative sexual pain to postoperative sexual discomfort. These women reported improved sexual functioning, increased sexual activity and intimacy with the partner, and reinstated feelings of being an adequate woman and sexual partner. In 1 of the 19 patients (5%), surgery did not result in decreased sexual pain, yet she continued to have intercourse. Five of the 19 patients (26%) stopped having intercourse because of pain; one woman had secondary vaginismus and another woman, in retrospect, had premorbid generalized unprovoked vulvodynia. Four of these women were unable to communicate with their partner about sexual matters and to change their sexual repertoire (satisfactorily) once they had ceased intercourse (attempts). Eighteen women (95%) reported a decrease of LS symptoms in daily life. CONCLUSION: Vulvar surgery seems an effective treatment for most women with LS who experience sexual pain owing to anatomic or epithelial changes and who wish to resume intercourse. To assess whether women might benefit from such surgery and/or whether (additional) sexual counseling is indicated, preoperative sexological couple-based consultation is needed. This consultation should exclude comorbid vaginismus and generalized unprovoked vulvodynia and index the couple's pre-existing sex life, including sexual communication skills, and the ability to incorporate non-coital pain-free sexual activities.

Motives for Vulvar Surgery of Women with Lichen Sclerosus.

INTRODUCTION: Women with lichen sclerosus (LS) may experience (superficial) dyspareunia or the inability to have vaginal intercourse due to painful fissures and narrowing of the vaginal introitus. A surgical procedure may contribute to the relief of these sexual pain problems. It is unknown what motives women have to undergo surgery in order to regain the ability to have sexual intercourse. Such knowledge can offer important insights that are indispensable when discussing the option of vulvar surgery with patients with LS and might prevent potential patient dissatisfaction. This study's purpose is to examine why women with LS decide to undergo vulvar surgery in order to restore intercourse. METHODS: Nineteen women with anogenital LS participated in audiotaped qualitative individual interviews, in which their motives for undergoing vulvar surgery to restore intercourse were explored retrospectively. Interview data were analyzed using the constant comparative method. RESULTS: Three main motives for wanting to undergo surgery in order to restore intercourse were found. These were the desire to be a "normal" woman, the desire to sexually satisfy the male partner, and the desire to regain the experience of intimacy and sexual enjoyment. Another reason for surgery was to reduce daily life LS symptoms. The sexual pain complaints prevented the women from living up to their norms about heterosexuality and gender roles. Being unable to have intercourse led women to feel inadequate as a woman and as a sexual partner. CONCLUSIONS: Women with LS may opt for surgery to restore their identity as a "normal" woman and sexual partner, to regain the experience of coital intimacy, and to be less bothered by LS symptoms in daily life. The present findings point to the importance of a thorough couple-based sexual history in which women's motives for and expectations of vulvar surgery will be explored in order to facilitate a good decision and to increase treatment satisfaction.

Predictors of task-persistent and fear-avoiding behaviors in women with sexual pain disorders.

INTRODUCTION: Dyspareunia and vaginismus are the most common sexual pain disorders (SPDs). Literature suggests that many women with dyspareunia continue with intercourse despite pain (task persistence), whereas many women with vaginismus avoid penetrative activities that may cause pain (fear avoidance). Both forms of sexual pain behavior may maintain or aggravate complaints. AIM: This study examined (i) whether women with SPD differ from pain-free controls in motives for sexual intercourse, sexual autonomy, maladaptive beliefs regarding vaginal penetration, and partner responses to pain; and (ii) which of these factors best predict whether women with SPD stop or continue painful intercourse (attempts). METHODS: Women with superficial dyspareunia (n = 50), women with lifelong vaginismus (n = 20), and pain-free controls (n = 45) completed questionnaires. MAIN OUTCOME MEASURES: For Aim 1, the main outcome measures were (i) motives for intercourse; (ii) sexual autonomy; (iii) maladaptive beliefs regarding vaginal penetration; and (iv) partner responses to pain. For Aim 2, sexual pain behavior (to continue or discontinue with painful intercourse) was the outcome measure. RESULTS: (i) Women with dyspareunia exhibited more mate guarding and duty/pressure motives for intercourse and were less sexually autonomous than controls. (ii) Symptomatic women had more maladaptive penetration-related beliefs than controls, with women with vaginismus reporting the strongest maladaptive beliefs. (iii) Partners of women with dyspareunia self-reported more negative responses to pain than those of women with vaginismus. (iv) The factors that best predicted sexual pain behavior were the partner responses to pain and the woman's maladaptive beliefs regarding vaginal penetration. CONCLUSIONS: Our findings reveal support for task persistence in women with dyspareunia and fear avoidance in women with lifelong vaginismus. As such, it is important to consider these distinct types of responding to sexual pain when treating SPD.

Cytomegalovirus viral load kinetics in patients with HIV/AIDS admitted to a medical intensive care unit: a case for pre-emptive therapy.

BACKGROUND: Cytomegalovirus (CMV) infection is associated with severe diseases in immunosuppressed patients; however, there is a lack of data for pre-emptive therapy in patients with HIV/AIDS. METHOD: This was a retrospective study, which enrolled patients diagnosed with HIV/AIDS (CD4<200 cells/µl), who had detectable CMV viral load (VL) during their stay in an adult medical intensive care unit between 2009-2012. RESULTS: After screening 82 patients' records, 41 patients met the enrolment criteria. Their median age was 37 (interquartile range [IQR]: 31-46), and median CD4 count was 29 cells/µl (IQR: 5-55). Sixteen patients (39%) had serial measurements of CMV VL before treatment with ganciclovir. Patients whose baseline CMV VL values were between 1,000-3,000 copies/ml had significantly higher values (median of 14,650 copies/ml) on follow-up testing done 4-12 days later. Those with undetectable VLs at baseline testing had detectable VLs (median of 1,590 copies/ml) mostly within 20 days of follow-up testing. Patients who had VLs >1,000 copies/ml at baseline testing had significantly higher mortality compared to those who had <1,000 copies/ml {hazard ratio of 3.46, p = 0.003 [95% confidence interval (CI): 1.55-7.71]}. Analysis of the highest CMV VL per patient showed that patients who had VLs of >5,100 copies/ml and did not receive ganciclovir had 100% mortality compared to 58% mortality in those who received ganciclovir at VLs of >5,100 copies/ml, 50% mortality in those who were not treated and had low VLs of <5,100 copies/ml, and 44% mortality in those who had ganciclovir treatment at VLs of <5,100 copies/ml (p = 0.084, 0.046, 0.037, respectively). CONCLUSION: This study showed a significantly increased mortality in patients with HIV/AIDS who had high CMV VLs, and suggests that a threshold value of 1,000 copies/ml may be appropriate for pre-emptive treatment in this group.

Automatic and deliberate affective associations with sexual stimuli in women with lifelong vaginismus before and after therapist-aided exposure treatment.

INTRODUCTION: The intense fear response to vaginal penetration in women with lifelong vaginismus, who have never been able to experience coitus, may reflect negative automatic and deliberate appraisals of vaginal penetration stimuli which might be modified by exposure treatment. AIMS: The aim of this study is to examine whether (i) sexual stimuli elicit relatively strong automatic and deliberate threat associations in women with vaginismus, as well as relatively negative automatic and deliberate global affective associations, compared with symptom-free women; and (ii) these automatic and more deliberate attitudes can be modified by therapist-aided exposure treatment. METHODS: A single target Implicit Association Test (st-IAT) was used to index automatic threat associations, and an Affective Simon Task (AST) to index global automatic affective associations. Participants were women with lifelong vaginismus (N = 68) and women without sexual problems (N = 70). The vaginismus group was randomly allocated to treatment (n = 34) and a waiting list control condition (n = 34). MAIN OUTCOME MEASURES: Indices of automatic threat were obtained by the st-IAT and automatic global affective associations by the AST, visual analogue scales (VAS) were used to assess deliberate appraisals of the sexual pictures (fear and global positive affect). RESULTS: More deliberate fear and less global positive affective associations with sexual stimuli were found in women with vaginismus. Following therapist-aided exposure treatment, the strength of fear was strongly reduced, whereas global positive affective associations were strengthened. Automatic associations did not differ between women with and without vaginismus and did not change following treatment. CONCLUSIONS: Relatively stronger negative (threat or global affect) associations with sexual stimuli in vaginismus appeared restricted to the deliberate level. Therapist-aided exposure treatment was effective in reducing subjective fear of sexual penetration stimuli and led to more global positive affective associations with sexual stimuli. The impact of exposure might be further improved by strengthening the association between vaginal penetration and positive affect (e.g., by using counter-conditioning techniques).

Evaluation of the Determine™ fourth generation HIV rapid assay.

Assays that detect p24 antigen reduce the diagnostic window period of HIV testing. Most point-of-care HIV assays have poor sensitivity to diagnose acute HIV infection as they only detect antibodies against HIV-1 and HIV-2 (HIV-1/2). This was a cross-sectional laboratory-based study that evaluated the performance of the Determine™ HIV-1/2 Ag/Ab Combo fourth generation rapid strip - currently the only rapid assay that detects both HIV-1/2 antibodies and p24 antigen. A total of 79 serum specimens (29 positive for HIV antibodies only, 14 positive for HIV antibodies and p24 antigen, 20 HIV-negative, and 16 positive for p24 antigen only) were used for the evaluation. Results were compared with those from validated fourth generation HIV ELISAs. The Determine™ Combo rapid strips had a sensitivity of 90.7% and a specificity of 100% for the detection of HIV-1/2 antibodies. Its sensitivity for the detection of p24 antigen was only 10% (3 out of 30 p24 antigen positive specimens). This implies that most acute HIV infections will be missed with this assay. The need for a point-of-care assay which can detect acute HIV infection reliably still remains, particularly for use in a high prevalence setting such as South Africa.

Attentional and affective processing of sexual stimuli in women with hypoactive sexual desire disorder.

Hypoactive sexual desire disorder (HSDD) is the most common sexual problem in women. From an incentive motivation perspective, HSDD may be the result of a weak association between sexual stimuli and rewarding experiences. As a consequence, these stimuli may either lose or fail to acquire a positive meaning, resulting in a limited number of incentives that have the capacity to elicit a sexual response. According to current information processing models of sexual arousal, sexual stimuli automatically activate meanings and if these are not predominantly positive, processes relevant to the activation of sexual arousal and desire may be interrupted. Premenopausal U.S. and Dutch women with acquired HSDD (n = 42) and a control group of sexually functional women (n = 42) completed a single target Implicit Association Task and a Picture Association Task assessing automatic affective associations with sexual stimuli and a dot detection task measuring attentional capture by sexual stimuli. Results showed that women with acquired HSDD displayed less positive (but not more negative) automatic associations with sexual stimuli than sexually functional women. The same pattern was found for self-reported affective sex-related associations. Participants were slower to detect targets in the dot detection task that replaced sexual images, irrespective of sexual function status. As such, the findings point to the relevance of affective processing of sexual stimuli in women with HSDD, and imply that the treatment of HSDD might benefit from a stronger emphasis on the strengthening of the association between sexual stimuli and positive meaning and sexual reward.

Classical conditioning of sexual response in women: a replication study.

INTRODUCTION: According to incentive motivation models, sexual stimuli play a crucial role in eliciting sexual arousal, desire, and behavior. Therefore, it seems highly valuable to investigate the process through which stimuli acquire motivational value. Although many theories of human sexual behavior assume that sexual stimuli obtain arousing properties through classical conditioning, systematic research on classical conditioning of sexual responses in humans is scarce. Recently, however, our research group observed conditioned genital responses in women using a differential conditioning procedure and genital vibrostimulation as unconditional stimulus (US). AIM: The aim of the present experiment was to perform an extended replication of this previous study to test the efficacy of our conditioning paradigm. METHODS: A differential conditioning experiment was conducted in 32 sexually functional women. Neutral pictures served as conditional stimuli (CSs) and genital vibrostimulation as US. Only one CS (the CS+) was followed by the US during the acquisition phase. Conditioned responses were assessed during the extinction phase. MAIN OUTCOME MEASURES: Vaginal pulse amplitude (VPA) and skin conductance level were assessed, and ratings of affective value and sexual arousal were obtained. RESULTS: As expected, during the extinction phase, VPA was higher in response to the CS+ than to the CS-. Also, the CS+ tended to be evaluated as more positive and as more sexually arousing than the CS-. In addition, the magnitude of conditioned subjective affect was related to scores on the Sexual Inhibition\Sexual Excitation Scales. Skin conductance levels showed no conditioning effect. CONCLUSIONS: Genital and subjective sexual responses were successfully modulated by the differential conditioning paradigm. This replication of our previous study confirms the effectiveness of our conditioning procedure and indicates that it may provide a fruitful paradigm for further research on associative sexual reward learning in humans.

Sexual desire, sexual arousal and hormonal differences in premenopausal US and Dutch women with and without low sexual desire.

The interaction between women's hormonal condition and subjective, physiological, and behavioral indices of desire or arousal remains only partially explored, in spite of frequent reports from women about problems with a lack of sexual desire. The present study recruited premenopausal women at two sites, one in the United States and the other in the Netherlands, and incorporated various measures of acute changes in sexual desire and arousal. A sample of 46 women who met criteria for Hypoactive Sexual Desire Disorder (HSDD) was compared to 47 women who experienced no sexual problems (SF). Half of each group used oral contraceptives (OCs). The specific goal was to investigate whether there is a relationship between women's hormone levels and their genital and subjective sexual responsiveness. Background demographics and health variables, including oral contraceptive (OC) use, were recorded and hormones (total testosterone (T), free testosterone (FT), SHBG, and estradiol) were analyzed along with vaginal pulse amplitude and self-report measures of desire and arousal in response to sexual fantasy, visual sexual stimuli, and photos of men's faces. Self-reported arousal and desire were lower in the HSDD than the SF group, but only for women who were not using oral contraceptives. Relationships between hormones and sexual function differed depending on whether a woman was HSDD or not. In line with prior literature, FT was positively associated with physiological and subjective sexual arousal in the SF group. The HSDD women demonstrated the opposite pattern, in that FT was negatively associated with subjective sexual responsiveness. The findings suggest a possible alternative relationship between hormones and sexual responsiveness in women with HSDD who have characteristics similar to those in the present study.

Cognitive-affective correlates and predictors of superficial dyspareunia.

This study investigated the role of cognitive-affective variables related to sexuality, chronic pain, individual and relational well-being in superficial dyspareunia. Although symptomatic women (n = 80) differed from complaint-free controls (n = 62) on all variables, sexuality related measures had the most important contribution into the prediction of group membership. Dyspareunia subgroups based on the presence/absence of a concomitant diagnosis of provoked vestibulodynia were only distinguishable on pain intensity but not on variables related to sexuality and psychological well-being. The present findings underscore the relevance of psychosexual factors in women with superficial dyspareunia.

Automatic and deliberate affective associations with sexual stimuli in women with superficial dyspareunia.

Current views suggest that in women with superficial dyspareunia the prospect of penile-vaginal intercourse automatically activates fear-related associations. The automatic activation of negative associations is assumed to interfere with the development of sexual arousal. In turn, this may further aggravate the dyspareunia-related complaints. To assess whether automatic negative associations are involved in this sexual pain disorder, women with superficial dyspareunia (n = 35) and a control group (n = 35) completed a modified pictorial Affective Simon Task (AST). Questioning the role of dysfunctional automatic associations in superficial dyspareunia, the AST indicated that symptomatic women displayed relatively positive rather than negative automatic associations with sexual stimuli. At the self-report level, however, affective associations with sex cues were significantly more negative for women with dyspareunia than for controls. This discrepancy between "reflective" and "reflexive" affective associations with sexual stimuli in women with dyspareunia points to the relevance of conscious appraisal and deliberate rather than automatic processes in the onset and maintenance of dyspareunia.
