Abstract
BACKGROUND Infections with Herpes simplex virus (HSV)-1 or -2 usually present as mild chronic recurrent disease, however in rare cases can result in life-threatening conditions with a large spectrum of pathology. Monoclonal antibody therapy has great potential especially to treat infections with virus resistant to standard therapies. HDIT101, a humanized IgG targeting HSV-1/2 gB was previously investigated in phase 2 clinical trials. The aim of this study was to develop a next-generation therapy by combining different antiviral monoclonal antibodies. METHODS A lymph-node derived phage display library (LYNDAL) was screened against recombinant gB from Herpes simplex virus (HSV) -1 and HDIT102 scFv was selected for its binding characteristics using bio-layer interferometry. HDIT102 was further developed as fully human IgG and tested alone or in combination with HDIT101, a clinically tested humanized anti-HSV IgG, in vitro and in vivo. T-cell stimulating activities by antigen-presenting cells treated with IgG-HSV immune complexes were analyzed using primary human cells. To determine the epitopes, the cryo-EM structures of HDIT101 or HDIT102 Fab bound to HSV-1F as well as HSV-2G gB protein were solved at resolutions < 3.5 Å. RESULTS HDIT102 Fab showed strong binding to HSV-1F gB with Kd of 8.95 × 10-11 M and to HSV-2G gB with Kd of 3.29 × 10-11 M. Neutralization of cell-free virus and inhibition of cell-to-cell spread were comparable between HDIT101 and HDIT102. Both antibodies induced internalization of gB from the cell surface into acidic endosomes by binding distinct epitopes in domain I of gB and compete for binding. CryoEM analyses revealed the ability to form heterogenic immune complexes consisting of two HDIT102 and one HDIT101 Fab bound to one gB trimeric molecule. Both antibodies mediated antibody-dependent phagocytosis by antigen presenting cells which stimulated autologous T-cell activation. In vivo, the combination of HDIT101 and HDIT102 demonstrated synergistic effects on survival and clinical outcome in immunocompetent BALB/cOlaHsd mice. CONCLUSION This biochemical and immunological study showcases the potential of an effective combination therapy with two monoclonal anti-gB IgGs for the treatment of HSV-1/2 induced disease conditions.

Abstract
This paper presents an experiment exploring message strategies to reduce the stigma of gynecological diseases and promote women's sexual and reproductive health. Drawing on the cognitive-affective-behavioral model of stigma, we propose that social norms and message framing as two message strategies, respectively, address the cognitive and affective components of the stigma of gynecological diseases, which lead to desired changes in the help-seeking intention as the behavioral component. We conducted a 3 (no norm vs. descriptive norm vs. descriptive plus injunctive norms) by 2 (gain-framed vs. loss-framed) between-subject experiment (N = 202). The results reveal that messages with the combination of descriptive and injunctive norms reduce the greatest cognitive components of stigma. Gain-framed messages induced fewer affective components than loss-framed ones. The results suggest that changes in the cognitive and affective components of stigma may sequentially lead to favorable changes in the behavioral component. This study contributes to public understanding of the stigma of gynecological diseases by disentangling the various components and identifying the specific message strategies for stigma reduction.

Silva S, Ayoub HH, Johnston C, Atun R, Abu-Raddad LJ. Estimated economic burden of genital herpes and HIV attributable to herpes simplex virus type 2 infections in 90 low- and middle-income countries: A modeling study. PLoS Med 2022; 19:e1003938. [PMID: 36520853 PMCID: PMC9754187 DOI: 10.1371/journal.pmed.1003938] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 11/08/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Economic losses due to herpes simplex infections in low- and middle-income countries (LMICs) are unknown. We estimated economic and quality-of-life losses due to genital herpes in 2019, in 90 LMICs, and from 2020 to 2030 in 45 countries in the World Health Organization (WHO) Africa. We additionally estimated economic losses due to human immunodeficiency virus (HIV) attributable to herpes simplex virus type 2 (HSV-2) infections. METHODS AND FINDINGS We estimated genital herpes-related spending on treatment, wage losses due to absenteeism, and reductions in quality of life, for individuals aged 15 to 49 years, living with genital herpes. Had HSV-2 had contributed to the transmission of HIV, we estimated the share of antiretroviral treatment costs and HIV-related wage losses in 2019 that can be attributed to incident and prevalent HSV-2 infections in 2018. For the former, we used estimates of HSV-2 incidence and prevalence from the global burden of disease (GBD) study. For the latter, we calculated population attributable fractions (PAFs), using the classic (Levin's) epidemiological formula for polytomous exposures, with relative risks (RRs) reported in literature. To extend estimates from 2020 to 2030, we modeled the transmission of HSV-2 in 45 African countries using a deterministic compartmental mathematical model, structured by age, sex, and sexual activity, which was fitted to seroprevalence gathered from a systematic review and meta-regression analysis. In the 90 LMICs, genital herpes contributed to US$813.5 million in treatment and productivity losses in 2019 (range: US$674.4 to US$952.2 million). Given observed care-seeking and absenteeism, losses are in the range of US$29.0 billion (US$25.6 billion to US$34.5 billion). Quality-of-life losses in the amount of 61.7 million quality-adjusted life years (QALYs) are also possible (50.4 million to 74.2 million). The mean annual cost of treatment and wage losses per infection is US$183.00 (95% CI: US$153.60 to US$212.55); the mean annual cost of quality-of-life losses is US$343.27 (95% CI: 272.41 to 414.14). If HSV-2 has fueled the transmission of HIV, then seroprevalent HSV-2 cases in 2018 can account for 33.2% of the incident HIV infections in 2019, with an associated antiretroviral therapy (ART) cost of US$186.3 million (range: US$163.6 to US$209.5 million) and 28.6% of HIV-related wage losses (US$21.9 million; range: US$19.2 to US$27.4 million). In the WHO Africa region, the 3.9 million seroprevalent genital herpes cases from 2020 to 2030 contributed to US$700.2 million in treatment and productivity losses. Additionally, quality-of-life losses in the range of 88 million to 871 million QALYs are also possible. If HSV-2 has contributed to the transmission of HIV, then in 2020, the PAF of HIV due to prevalent HSV-2 will be 32.8% (95% CI: 26.7% to 29.9%) and due to incident infections will be 4.2% (95% CI: 2.6% to 3.4%). The PAF due to prevalent infections will decline to 31.0% by 2030 and incident infections to 3.6%. Though we have accounted for the uncertainty in the epidemiological and economic parameter values via the sensitivity analysis, our estimates still undervalue losses due to limiting to the 15- to 49-year-old population. CONCLUSIONS Economic losses due to genital herpes in LMICs can be large, especially when considering the lifelong nature of the disease. Quality-of-life losses outweigh spending on treatment and reductions in productivity. If HSV-2 has contributed to the spread of HIV in LMICs, then nearly one third of antiretroviral costs and HIV-related wage losses can be attributed to HSV-2. Given the magnitude of the combined losses, a vaccine against HSV-2 must be a global priority.

Abstract
The herpes virus was named by the Greek physician Hippocrates who called it herpes because the lesions appeared near each other and were vesicular. Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae are subfamilies of the human herpes virus family. The Alphaherpesvirinae subfamily includes the simplex viruses-HSV-1 and HSV-2-and varicellovirus-varicella zoster virus. There are more than 200 members of the Herpesviridae family capable of infecting different species, 8 of which are known to cause disease in humans. The simplex viruses can cause lifelong genital infections, and despite the prevalence of HSV-1 and HSV-2 infections in the United States decreasing in the past 20 years, infections with these viruses continue to contribute to significant clinical and psychological morbidities.

Abstract
OBJECTIVE This review sought to identify the experiences of persons living with genital herpes and what interventions improve the health-related quality of life of young people and adults with primary or recurrent genital herpes. INTRODUCTION Genital herpes is commonly associated with psychosocial challenges. However, a growing body of evidence suggests that its impact can be ameliorated through pharmacological and psychosocial interventions. INCLUSION CRITERIA This review considered English- and German-language studies of community-dwelling males and females, of any ethnicity and geographical location, aged 15 years and older, who had primary or recurrent genital herpes. The quantitative component of the review included studies that reported on the virus' impact on patients' health-related quality of life and/or the efficacy of interventions in improving their health-related quality of life. Studies compared antiviral suppression therapies and psychological interventions with usual care or placebo, or against one another. The qualitative component of the review included studies that investigated the perceptions and experiences of young people and adults with genital herpes. METHODS Eleven databases were searched from January 1980 to March 2020. The JBI approach to mixed methods systematic reviews was followed at each stage of the review, and a convergent segregated approach to synthesis and integration was adopted. RESULTS A total of 31 publications covering 30 studies were deemed suitable for inclusion. Studies encompassed quantitative (n = 27, across 28 publications), qualitative (n = 1), and mixed methods (n = 2) designs. Critical appraisal scores were variable, particularly among the randomized controlled trials and the analytical cross-sectional studies. All studies were included regardless of methodological quality. The quantitative components identified that depression, illness concern, stress, anxiety, isolation, stigma, and a lowering of self-esteem, self-concept, self-confidence, and health-related quality of life may be experienced by both those newly diagnosed with genital herpes and those with recurrences. It was also identified that genital herpes can have an adverse effect on work or school, sexual relationships, and relationships with friends and family. Depression was found to significantly decrease after self-hypnosis and certain psychosocial interventions. Anxiety significantly decreased following pharmacological treatment, psychosocial interventions, and hypnosis. Psychosocial interventions significantly improved mood, and a self-help module with counseling significantly improved participants' satisfaction with intimate relationships and their self-esteem. Pharmacological treatment significantly improved health-related quality of life; however, there were no significant differences between different active treatment regimens. The qualitative component of the review led to the identification of two synthesized findings: "Disclosure of a diagnosis of genital herpes poses a dilemma for people who have the virus" and "A diagnosis of genital herpes has a significant emotional impact for the individual."Integration of quantitative and qualitative evidence revealed a consensus that a diagnosis of genital herpes has a significant emotional impact for individuals and that disclosure is stressful, affects relationships, and affects health-related quality of life; however, there is a lack of consensus regarding efficacy of different interventions. CONCLUSIONS Genital herpes can lead to extreme emotional, social, relational, and sexual distress, but there is insufficient knowledge concerning which interventions best improve health-related quality of life. More high-quality research is required.

Abstract
Background There is a significant global burden of herpes simplex virus (HSV) related genital ulcer disease yet little is known about its impact on quality of life. This systematic review aimed to identify studies that quantitatively evaluated the effect of genital herpes on various aspects of health-related quality of life.
Methods Six databases were searched (MEDLINE, EMBASE, NHS Economic Evaluation Database, Health Technology Assessment, Database of Abstracts of Reviews of Effects, Web of Science Core Collection) for primary quality of life and economic evaluations of genital herpes from January 1, 2000 to January 7, 2021. Qualitative studies or those without primary data were excluded. Two authors independently extracted data from the publications. The study’s registration number with PROSPERO was CRD42021239410. Findings We identified 26 relevant publications: 19 presented primary quality of life data, and seven were economic evaluations. The primary studies presented a range of condition-specific tools for describing the quality of life in individuals with genital herpes, but only one study used a direct valuation that could be used to generate utility weights. All economic evaluations of HSV infection were from high-income country settings. Most (6 of 7) focused on neonatal HSV infection with utilities adopted from studies prior to 2000. Interpretation The extant literature on genital herpes-related quality of life is limited and requires updating. We recommend future studies be conducted in geographic- and population- diverse settings, and use preference-based condition-specific or generic-instruments to better inform economic modelling.

Abstract
Background Patients with sexually transmitted infections (STIs) suffer not only with the physical problems but also with various psychological problems. Majority of bacterial STIs are treatable in a short period, while viral STIs may persist for longer duration or have frequent recurrences. Aims and Objectives The aim of the study was To study different aspects of psychological health and well-being in patients with STIs. Materials and Methods Study design was a prospective cross-sectional hospital-based study. Data were collected during July 2016-April 2018. STIs were divided into four groups (genital herpes, genital warts, and genital discharge and syphilis). One way analysis of variance and Scheffe Test were used for analysis of the data. Results A total of 410 patients were included in the study. Majority of patients were suffering with genital herpes (139), followed by warts (104), discharge (92), and syphilis (75). Genital herpes and genital warts indicated significantly more cognitive affective (CA) depression as compared to the patients suffering with syphilis. Satisfaction with life was more with genital discharge and syphilis in comparison to the patients with genital warts and genital herpes. Genital herpes showed more perceived stress in comparison to genital discharge. Genital warts indicated more somatic depression as compared to syphilis and genital discharge patients while genital herpes showed more somatic depression than in patients suffering with genital discharge. Genital warts and genital herpes indicated significantly more overall depression as compared to the patients suffering with syphilis. Conclusion Overall depression was more in patients with genital herpes and warts. The findings provide empirical bases for extended studies on behavioral intervention programs.

Abstract
Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted disease that affects approximately 500 million individuals globally. There is currently no approved vaccine to prevent HSV-2 infection. EXCT4 is a truncated form of the mature glycoprotein G-2 (mgG-2) that unlike full mature form is secreted by expressing cells enabling it to be rapidly scaled up for production. The current study examined whether EXCT4 immunity in mice could be further enhanced through use of adjuvants. EXCT4 formulated with Advax-CpG adjuvant induced a strong Th1-type immune response characterized by interferon gamma (IFN-γ) and protected animals against a lethal genital challenge with HSV-2. This response was associated with reduced viral load in vaginal washes, spinal cord, and dorsal root ganglia. Together the results provide proof of concept that EXCT4 formulated with Advax-CpG adjuvant is a promising HSV-2 vaccine candidate warranting further investigation.

Abstract
Background
Infection with the herpes simplex virus (HSV) is common but not well understood. Furthermore, there remains a social stigma surrounding HSV that can have psychosocial implications for those infected. Despite many patients infected with HSV experiencing mild-to-severe physical symptoms, only one subeffective treatment is available. A registry collecting real-world data reported by individuals potentially infected with HSV could help patients to better understand and manage their condition.
Objective
This study aimed to report on the development of a registry to collect real-world data reported by people who might be infected with HSV.
Methods
A case study design was selected as it provides a systematic and in-depth approach to investigating the planning phase of the registry. The case study followed seven stages: plan, design, prepare, collect, analyze, create, and share. We carried out semistructured interviews with experts, which were thematically analyzed and used to build use cases for the proposed registry. These use cases will be used to generate detailed models of how a real-world evidence registry might be perceived and used by different users.
Results
The following key themes were identified in the interviews: (1) stigma and anonymity, (2) selection bias, (3) understanding treatment and outcome gaps, (4) lifestyle factors, (5) individualized versus population-level data, and (6) severe complications of HSV. We developed use cases for different types of users of the registry, including individuals with HSV, members of the public, researchers, and clinicians.
Conclusions

Abstract
BACKGROUND
Infection with the herpes simplex virus (HSV) is common but not well understood. Furthermore, there remains a social stigma surrounding HSV that can have psychosocial implications for those infected. Despite many patients infected with HSV experiencing mild-to-severe physical symptoms, only one subeffective treatment is available. A registry collecting real-world data reported by individuals potentially infected with HSV could help patients to better understand and manage their condition.
OBJECTIVE
This study aimed to report on the development of a registry to collect real-world data reported by people who might be infected with HSV.
METHODS
A case study design was selected as it provides a systematic and in-depth approach to investigating the planning phase of the registry. The case study followed seven stages: plan, design, prepare, collect, analyze, create, and share. We carried out semistructured interviews with experts, which were thematically analyzed and used to build use cases for the proposed registry. These use cases will be used to generate detailed models of how a real-world evidence registry might be perceived and used by different users.
RESULTS
The following key themes were identified in the interviews: (1) stigma and anonymity, (2) selection bias, (3) understanding treatment and outcome gaps, (4) lifestyle factors, (5) individualized versus population-level data, and (6) severe complications of HSV. We developed use cases for different types of users of the registry, including individuals with HSV, members of the public, researchers, and clinicians.
CONCLUSIONS
This case study revealed key considerations and insights for the development of an appropriate registry to collect real-world data reported by people who might be infected with HSV. Further development and testing of the registry with different users is required. The registry must also be evaluated for the feasibility and effectiveness of collecting data to support symptom management. This registry has the potential to contribute to the development of vaccines and treatments and provide insights into the impact of HSV on other conditions.

Abstract
Background GEN-003 is a candidate therapeutic vaccine for genital herpes simplex virus type 2 (HSV-2). We compared virologic and clinical impact of varying GEN-003 doses. Methods Adults with symptomatic HSV-2 received placebo or GEN-003 (30 or 60 µg antigen with 25, 50, or 75 µg adjuvant). Viral shedding and lesion rates before vaccination were compared with those measured immediately after vaccination, then at weeks 29-33 and 53-57 after last dose. Results Compared with baseline shedding rates, the rate ratios for viral shedding immediately after treatment were as follows: 0.82 (95% confidence interval [CI], 0.49-1.36), 30 µg antigen/25 µg adjuvant (30/25) dose; 0.64 (95% CI, 0.45-0.92), 30/50 dose; 0.63 (95% CI, 0.37-1.10), 30/75 dose; 0.56 (95% CI, 0.36-0.88), 60/25 dose; 0.58 (95% CI, 0.38-0.89), 60/50 dose; 0.45 (95% CI, 0.16-0.79), 60/75 dose; and 0.98 (95% CI, 0.76-1.26), placebo. Lesion rate reductions by GEN-003 ranged from 31% to 69%, but lesion rates also decreased among placebo recipients (62%). Reductions in shedding and lesion rate were durable for 12 months for the 60 µg antigen plus 50 or 75 µg adjuvant groups. No serious adverse events occurred with vaccination. Conclusions The most efficacious vaccine combinations for GEN-003 were the 60 µg/50 µg and 60 µg/75 µg doses.

Abstract
Sexually transmitted diseases (STDs) continue to be underrecognized leading to devastating health and economic consequences. Emergency clinicians play an important role in diagnosing and managing STDs and in improving health care outcomes for both the patient and their partners. In addition, antibiotic resistance and emerging infections continue to challenge providers in clinical practice. This review focuses on the cause, history, physical examination, diagnostic studies, and treatment strategies for bacterial vaginosis, chlamydia, genital herpes, gonorrhea, human papillomavirus, granuloma inguinale, Lymphogranuloma Venereum, Mycoplasma genitalium, syphilis, and trichomoniasis.

Epilepsy Behav 2018; 82:111-118. [PMID: 29604483 DOI: 10.1016/j.yebeh.2018.02.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Revised: 02/16/2018] [Accepted: 02/16/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVES The aim of this paper was to describe the development and psychometric evaluation of new Epilepsy Disclosure Scales (EDSs) for youths with epilepsy (YWE) and their parents. METHODS Developing the EDSs for youths and parents comprised a number of stages, including questionnaire construction and item development for the new EDSs (consisting of a pilot and review of the newly developed EDSs) and psychometric evaluation of the measures to assess their appropriateness, factor structure, reliability, and validity. Psychometric properties were determined using a cross-sectional survey of 47 YWE and 72 parents. RESULTS Two scales were developed to assess the epilepsy disclosure behaviors of YWE and their parents; that is, the extent to which they tell and talk to others about the child's epilepsy. The youth version of the EDS comprised six items and had a unidimensional factor structure that explained 55% of the variance. The parent version of the EDS also consisted of six items, with a single factor explaining 47% of the variance. The suitability, validity, and reliability of the youth and parent versions of EDSs were supported by positive indicators, such as a high Cronbach's alpha (representative of good internal consistency) and the confirmation of a number of hypothesized relationships between epilepsy disclosure and psychosocial and illness attitude variables (demonstrative of their convergent validity). CONCLUSION Prior to the development of these instruments, no valid and reliable measures existed that could suitably capture disclosure amongst populations living with epilepsy. The youth and parent versions of the EDS are valid, reliable, brief, and easily administered and thus could prove useful in research as well as in the clinical setting. These scales will enable researchers and clinicians to profile the epilepsy disclosure behaviors of YWE and their parents, which play an important role and have implications both for the psychosocial wellbeing of families living with epilepsy and for epilepsy-related stigma.

Abstract
According to the World Health Organization, antimicrobial resistance is one of the most severe threats to public health. Since the 1950's contemporary farming of pigs has been heavily dependent on the use of antibiotics. Recently, concerned experts of public health have become more outspoken, often, criticizing pig farmers for social irresponsibility and gambling with public health. Danish pig farmers are internationally renewed for their relatively low use of antibiotics. Nevertheless, the public criticism aimed at farmers is relatively strong in Denmark. Based on qualitative interviews with 30 pig farmers and 21 public health experts, this article sets out how pig farmers, according to public health experts, threaten public health and how pig farmers, according to the farmers, experience and internalize stigmatization related to their lives as farmers. By focusing on Danish pig farmers' experiencing public condemnation from scientific experts as well as in their local communities, this article proceeds along the line of existing research on health-related stigmatization.

Abstract
Purpose Herpes simplex virus 2 (HSV-2) causes genital herpes, one of the most common sexually transmitted infections (STIs) in the U.S. HSV-1, commonly associated with cold sores, is increasing as a cause of genital herpes. Abstinence-only sexual health classes, commonly taught in Virginia, generate young adults who are under-educated in sexual health, increasing STI risks. College students in southwest Virginia were surveyed to assess comprehensiveness of high school health education regarding HSV-1 and HSV-2 and to identify students’ preferred methods for STI education. Methods To obtain data on knowledge of HSV, comprehensiveness of sexual health education in high school, and preferred learning methods, 237 college students participated in an online questionnaire and 28 students were interviewed using structured interviews. Results Questionnaire and interview data indicated that Family Life Education classes need to include more comprehensive information on prevention, viral transmission, and differences between HSV-1 and HSV-2. The majority of total respondents (both the questionnaire and interview) (65%) reported non-comprehensive high school sexual health education. The majority of interview (79%) and questionnaire (55%) respondents wished they had learned more about herpes and other STIs in high school. Education preferences of both interviewed and surveyed respondents included interactive internet programs or games, more realistic lectures, and learning about STIs later in high school when students reported greater sexual activity. Conclusion Our results indicate that more comprehensive sexual health education is needed and wanted by students in southwest Virginia. More relevant educational programs should be implemented for VA high school students utilizing technology and interactive methods to improve student engagement in sexual health education. Implications and contribution These studies provide information on knowledge of herpes simplex viruses among college students, comprehensiveness of sexual health education received in high schools, and preferred methods to learn about HSV and other STIs. These studies inform the facilitation of improved health education practices and programs for high school and college students.

Abstract
Objectives This study aimed to explore the challenges parents of children with epilepsy (CWE) experienced when deciding to disclose their child's epilepsy diagnosis to others. Methods Using a qualitative exploratory design, interviews were conducted with 34 parents (27 mothers and 7 fathers) of 29 CWE (aged 6-16 years). Parents were recruited from a neurology clinic of a specialist children's hospital and from a national epilepsy association. Interviews were directed by a semi-structured guide informed by a review of the literature. Data were transcribed verbatim, imported into NVivo, coded and thematically analysed. Results Findings revealed five themes representative of the core disclosure challenges parents encountered, many of which promoted concealment and/or selective disclosure, namely: seeking normalcy for the child, the invisibility of epilepsy, negative reactions to disclosure, contending with poor public perceptions of epilepsy and coming to terms with the diagnosis. Discussion This study presents crucial information for healthcare professionals (HCPs) who help families to navigate the disclosure decision-making process. Providing HCPs working with families living with epilepsy with insight into diagnosis disclosure challenges will enable them to recognise the support needs of parents and work collaboratively with families to tackle such difficulties, ultimately improving their psychosocial wellbeing.

Abstract
Despite its highly prevalent and stigmatizing nature, genital herpes has received little attention from stigma researchers relative to other sexually transmitted infections. This limitation is of great relevance to researchers and practitioners in both clinical and healthcare settings, given that stigma can cause psychological distress and hinder disclosure to sexual partners, hence contributing to the spread of genital herpes. The present research developed and examined the psychometric properties of a quantitative measure of genital herpes stigma. Two hundred individuals diagnosed with genital herpes recruited through online genital herpes support groups completed a survey containing 37 items adapted from the HIV Stigma Scale, questions about demographic and herpes-related characteristics, and measures of relevant psychosocial variables. A confirmatory factor analysis yielded an 18-item scale with four factors: personalized stigma, disclosure concerns, negative self-image, and concern with public attitudes. All subscales demonstrated good internal consistency, with Cronbach alphas ranging from 0.74 to 0.87. Construct validity was supported by correlations with relevant psychosocial variables, including negative affect, rumination, and perceived social support. As a psychometrically sound assessment tool, the Genital Herpes Stigma Scale can be used in both clinical and research settings to facilitate future efforts to alleviate the negative psychological consequences of this incurable viral infection.

Abstract
INTRODUCTION HSV-1 and HSV-2 are among the most common causes of sexually transmitted infections (stis) globally. these infections are strongly associated with increased risk of hiv acquisition and rare, but devastating, neonatal disease. available treatment options can reduce HSV transmission and improve quality of life. accurate diagnosis early in disease can improve patient management. Areas covered: This paper describes the clinical manifestations of HSV infection often used for clinical diagnostic purposes. The paper then describes the evolution of laboratory diagnostic assays. Serology, culture and molecular diagnostics are described since all are currently in use. The features and performance characteristics of the cobas 4800 HSV1 and HSV2 Test (cobas HSV) on the cobas 4800® system (cobas 4800) are described in detail. Expert commentary: Diagnosis of HSV has historically been unreliable or technically difficult, but the availability of molecular assays such as the cobas HSV test for detection and typing of herpes can improve our ability to correctly manage this disease. Utilization of tools such as the cobas HSV assay may help shorten the time to accurate diagnosis and treatment thus potentially reducing the risk of transmission and the global burden of HSV.

Abstract
The first UK prosecution for genital herpes simplex virus (HSV) transmission in 2011 attracted strong criticism from medical experts. To address the dearth of research on the topic, this study aimed to explore the nature of advice given to patients by the multidisciplinary team (MDT) in the West of Scotland on HSV disclosure to partners. Ten semi-structured interviews with members of the MDT were conducted and the interviews were analysed using Burnard's Thematic Content Analysis. Four themes emerged which explored practitioners' knowledge of HSV and their feelings regarding the emotional aspects of the diagnosis on clients including the challenges of discussing disclosure. Within this framework, participants' attitudes to the legal prosecution were also surveyed. This study revealed that participants had good knowledge about HSV. Furthermore, participants believed disclosure to be the patient's choice and had not altered their practice to advise disclosure to all partners in accordance with local protocol. However, there was a general consensus that disclosure was not required due to the prevalence of HSV and prevalence was used to dissipate emotional reactions to HSV diagnosis.

Abstract
BACKGROUND This study aimed to quantify cystic fibrosis (CF) disclosure and examine associations between disclosure and psychosocial and health outcomes. METHODS Participants completed measures assessing disease disclosure and psychosocial outcomes. Data from chart reviews and pharmacy records were obtained. RESULTS Participants (N=128; ages 16-63) were more likely to disclose to romantic partners (97%) and close friends (94%) than to casual friends (79%), bosses (71%), or co-workers (53%). Participants reported more comfort discussing CF with and doing treatments in front of romantic partners and close friends than other groups. Disclosure was associated with higher social support, social functioning, and medication adherence self-efficacy. Lower lung-function was associated with disclosure to bosses and co-workers. CONCLUSIONS Clinicians should consider discussing disclosure with patients, as limited disclosure may have a negative impact on psychosocial outcomes.

Abstract
Epidemiologic data demonstrate that women involved with the criminal justice system in the United States are at high risk for sexually transmitted infections, including herpes simplex virus type 2 (HSV-2). Female defendants were recruited from a misdemeanor court to assess whether brief framed messages utilizing prospect theory could encourage testing for HSV-2. Participants were randomly assigned to a message condition (gain, loss, or control), completed an interviewer-administered survey assessing factors associated with antibody test uptake/refusal and were offered free point-of-care HSV-2 serologic testing. Although individuals in the loss-frame group accepted testing at the highest rate, an overall statistical difference in HSV-2 testing behavior by group (p ≤ .43) was not detected. The majority of the sample (74.6%) characterized receiving a serological test for HSV-2 as health affirming. However, this did not moderate the effect of the intervention nor was it significantly associated with test acceptance (p ≤ .82). Although the effects of message framing are subtle, the findings have important theoretical implications given the participants' characterization of HSV-2 screening as health affirming despite being a detection behavior. Implications of study results for health care providers interested in brief, low cost interventions are also explored.

Abstract
OBJECTIVE The aims of this study were to examine pre-existing videos in order to explore the motivation for, possible approaches to, and timing and context of disclosure of genital herpes infection as described by the lay public. METHODS A thematic content analysis was performed on 63 videos submitted to an Australian online contest sponsored by the Australian Herpes Management Forum and Novartis Pharmaceuticals designed to promote disclosure of genital herpes. RESULTS Videos either provided a motivation for disclosure of genital herpes or directed disclosure without an explicit rationale. Motivations included manageability of the disease or consistency with important values. Evaluation of strategies and logistics of disclosure revealed a variety of communication styles including direct and indirect. Disclosure settings included those that were private, semiprivate and public. Disclosure was portrayed in a variety of relationship types, and at different times within those relationships, with many videos demonstrating disclosure in connection with a romantic setting. CONCLUSIONS Individuals with genital herpes are expected to disclose to susceptible partners. This analysis suggests that understanding lay perspectives on herpes disclosure to a partner may help healthcare providers develop counselling messages that decrease anxiety and foster disclosure to prevent transmission.

Abstract
Despite the high prevalence of herpes simplex virus type 2 (HSV-2), testing for asymptomatic infections is uncommon. One population for whom targeted interventions may be prioritized include individuals involved with the correctional system. Here we describe the acceptability of a novel HSV-2 screening program, implemented in a court setting, as a possible intervention for corrections-involved women. Female defendants completed an interviewer administered survey assessing factors associated with uptake/refusal of free point-of-care HSV-2 serologic testing and HSV-2 seropositivity. Participants included 143 women, 18-62 years old (mean 32.85) with diverse ethnicities. The majority (65.7%) accepted testing and 62.4% tested HSV-2 seropositive. Factors independently associated with test acceptance included higher perceived susceptibility to genital herpes infection and not receiving a preventative health screen. Women who were seropositive tended to be older, Black, report having previous STI, and be arrested on a prostitution charge. Findings suggest point-of-care testing in a court setting is acceptable to women and can be implemented to improve case finding of STI.

Abstract
BACKGROUND Herpes simplex virus (HSV) is one of the most common sexually transmisible infections worldwide. HSV-associated stigma negatively impacts emotional and sexual health, suggesting a need for novel approaches to reducing stigma. The aims of this study were to describe the range of destigmatising strategies used by the public in brief online videos, and to describe videos that were successful or unsuccessful in creating a destigmatising message. METHODS A thematic content analysis was performed on 103 publicly produced YouTube videos designed to destigmatise HSV infection for an Australian online contest. RESULTS Five destigmatising strategies were identified: providing information, normalising through familiarity, promoting disclosure, negating a negative perception and expressing moral indignation. Most videos employed multiple strategies. Regarding the degree of destigmatisation achieved, videos were coded as unsuccessful, successful, mixed or neutral. Unsuccessful and successful videos often employed the same strategies, but differed in their ability to balance positive and negative messages about HSV and to manage affective content. Some videos were successful despite not providing information about HSV. Mixed videos were appreciated differently in different contexts, and the use of humour was especially problematic. Neutral videos tended to exclusively provide information while avoiding affective content. CONCLUSIONS Efforts to reduce HSV-associated stigma may be unsuccessful and may even perpetuate stigma. Special attention must be paid to balance and to affective content, specifically humour, when attempting to convey a destigmatising message. Doing so may help reduce the role stigma plays as a barrier to appropriate care for patients with HSV infection.

Abstract
STUDY OBJECTIVE Genital herpes (HSV) is exceedingly common in the United States and women are disproportionally affected. This study aims to describe young women's beliefs about HSV and examine the correlates of those beliefs. DESIGN A 40-item Herpes Representation measure (HSV-RoSTD) and a demographic questionnaire were administered to a convenience sample of young women. Data analysis included descriptive statistics, t-tests and Pearson's correlations. SETTING Four women's health clinics and one large state university. PARTICIPANTS 302 women aged 18-24 years. INTERVENTIONS None. MAIN OUTCOME MEASURES Four dimensions of HSV representations (cause, identity, future perspective, and psychosocial consequences), age and STD testing history. RESULTS Nearly all (98%) believed that HSV would result in genital sores and 68% believed they could tell if their sexual partner had HSV. Most (89%) understood the longevity of HSV; however, 30% believed that they could take a pill to get rid of the infection, and 15% indicated that it was likely they would die from HSV. Negative beliefs about the psychosocial impact of HSV were common as 95% indicated they would be depressed and 90% indicated concern about sex and partner notification. Those who were younger and those who had never been tested for STDs believed a genital herpes infection is highly symptomatic. Finally, negative beliefs about the psychosocial consequences of HSV were associated with beliefs about HSV being symptomatic, having a negative impact on future health, and being associated with sexual risk behaviors. CONCLUSIONS Young women have misconceptions about HSV, particularly regarding the symptomatology and the role of HSV medication. Noteworthy concerns about the negative psychosocial consequences of an HSV diagnosis were also raised, all of which have implications for young women's sexual health.

Abstract
Illness stigmatization among inflammatory bowel diseases (IBDs) is poorly understood. We aim to characterize internalized stigma and stigma resistance in IBD patients, and evaluate their relationships to outcomes. A total of 191 IBD patients reported internalized stigma, resistance, demographic and clinical information, and several outcomes: health-related quality of life (HRQOL), psychological distress, self-esteem, and self-efficacy. Overall 36% experienced internalized stigma and 88% moderate to high stigma resistance behaviors. Internalized stigma strongly related to poorer outcomes while resistance demonstrated a weaker, opposite effect. Internalized stigma and stigma resistance are important considerations for IBD outcomes. Interventions to reduce internalized stigma and leverage resistance are warranted.

Abstract
Stigma is a powerful social phenomenon with insidious health implications. Understanding stigma as it applies to various populations is imperative for nurses as it enables nurses to enhance individual patient care and nurses are well positioned to influence both social and health care policies which may exacerbate the experience of stigma. This article is a report of a study to explore the experiences of women who provide long-term foster care. Interviews were conducted with 20 women who provided long-term foster care in Australia. Data were coded according to the components of stigma described by Link and Phelan (2001). Findings reveal participants rejected the label of foster carer to avoid the negative stereotype. When unable to conceal their foster carer label, participants experienced social isolation and status loss. Moreover, participants felt marginalized and disempowered within the governing systems.
