BACKGROUND: Plasmodium gametocytes are sexual stages transmitted to female Anopheles mosquitoes. While Plasmodium parasites can be differentiated microscopically on Giemsa-stained blood smears, molecular methods are increasingly used because of their increased sensitivity. Molecular detection of gametocytes requires methods that discriminate between asexual and sexual stage parasites. Commonly tested gametocyte-specific mRNAs are pfs25 and pfs230 detected by reverse transcription polymerase chain reaction (RT-PCR)...

Recently nanoparticle-based vaginal drug delivery formulations have been acquiring great attention for the administration of peptide based-vaccines or microbicides to prevent or treat sexually transmitted diseases. In this work, a straightforward and efficient strategy for the vaginal application and release of peptide-loaded mucoadhesive nanoparticles was developed. This essentially consists of chitosan nanoparticles encapsulated in suitable hydrophilic freeze-dried cylinders. Chitosan nanoparticles are responsible for carrying the peptide drug and allowing adhesion to the vaginal mucosal epithelium...

CONTEXT: HIV and syphilis infections are common in military personnel in sub-Saharan Africa, which impact combat preparedness and increase demands on the military health care system. The prevalence of HIV is estimated at 1.5% among the general population (15-49 years of age) of Sierra Leone, and the estimated syphilis prevalence ranged from 1.5% to 5.2% based on regional studies. We examined the prevalence and risk factors for these two common sexually transmitted infections in the Sierra Leone military personnel...

BACKGROUND: Compared with the general population in low- and middle-income countries, military members tend to be male, young, travel more frequently away from their main sexual partners, drink more alcohol and have a consistent source of income. All of these factors may lead to an increased risk of contracting HIV. OBJECTIVE: In response, the Department of Defense HIV/AIDS Prevention Program advocates for the integration of HIV prevention "building blocks" into military health services to reduce the risk of acquiring HIV among foreign uniformed services...

Neisseria gonorrhoeae is one of the most prevalent sexually transmitted infections worldwide. This obligate human pathogen has been extensively studied in vitro, where bacterial factors that are known to contribute to gonococcal disease and their regulation are relatively well defined. However, these in vitro experimental conditions only loosely replicate the host specific environment encountered by the bacteria in vivo. We recently reported on the complete gonococcal transcriptome expressed during natural human mucosal infection using RNA-seq analysis...

Using respondent driven sampling, we conducted a cross-sectional bio-behavioral survey among men who have sex with men (MSM) in Bamako, Mali. Eligibility criteria included age ≥18 years and having had sex with another man in the last 6 months. We enrolled 552 MSM, 99.6% were tested for HIV. MSM in Bamako were young (69.6% ≤24 years) and educated (63.7% ≥secondary). HIV prevalence among MSM in Bamako was 13.7; 90.1% of HIV-infected men were unaware of their HIV status. Almost one-third had never been tested for HIV...

Zika virus (ZIKV) is a member of the Flaviviridae family causing asymptomatic or mildly symptomatic infections with fever, rash, arthralgia and headache. It is transmitted by the Aedes species mosquitoes and also sexually and transplacentally, and has been recently associated with congenital neurologic birth defects in South and Central America. We report the case of a newly married couple from Greece who travelled to Cuba for their honeymoon and developed mild symptoms consistent with arboviral infection. After returning to Greece, they were found to have been infected by Zika virus during their honeymoon...

OBJECTIVES: HIV and herpes simplex virus type 2 (HSV-2) infections are sexually transmitted and propagate in sexual networks. Using mathematical modeling, we aimed to quantify effects of key network statistics on infection transmission, and extent to which HSV-2 prevalence can be a proxy of HIV prevalence. DESIGN/METHODS: An individual-based simulation model was constructed to describe sex partnering and infection transmission, and was parameterized with representative natural history, transmission, and sexual behavior data...

BACKGROUND: Molluscum contagiosum is a common skin infection that is caused by a pox virus and occurs mainly in children. The infection usually resolves within months in people without immune deficiency, but treatment may be preferred for social and cosmetic reasons or to avoid spreading the infection. A clear evidence base supporting the various treatments is lacking.This is an update of a Cochrane Review first published in 2006, and updated previously in 2009. OBJECTIVES: To assess the effects of specific treatments and management strategies, including waiting for natural resolution, for cutaneous, non-genital molluscum contagiosum in people without immune deficiency...

BACKGROUND: Human papillomavirus (HPV) is the most common sexually transmitted agent, and it can cause cervical lesions and cancer in females. Currently, information regarding the prevalence of HPV in Cyprus is lacking. The aim of this study was to evaluate the HPV type-specific prevalence in 596 women, aged 19-65 years, with cytological abnormalities. Additionally, in a subset of 348 women for whom cytology results of the Pap test were available, the association between HPV infection and cervical disease was investigated...

INTRODUCTION: Condyloma Acuminata (CA) is a common viral sexually transmitted disease. Although various treatment modalities are available for treating CA, but none of them can achieve 100% response rate. In a search for better response rate and less recurrence rate, the combination of cytotoxic agent Podophyllin with ablative liquid nitrogen cryotherapy was evaluated over cryotherapy alone. AIM: To evaluate the synergistic effect of Podophyllin as a chemotherapeutic adjunct to an ablative therapy of liquid nitrogen cryotherapy versus liquid nitrogen cryotherapy alone in the treatment of CA...

When used correctly and consistently, the male condom offers triple protection from unintended pregnancy and the transmission of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). However, with health funding levels stagnant or falling, it is important to understand the cost and health impact associated with prevention technologies. This study is one of the first to attempt to quantify the cost and combined health impact of condom use, as a means to prevent unwanted pregnancy and to prevent transmission of STIs including HIV...

BACKGROUND: In sub-Saharan Africa improving the deferral of at-risk blood donors would be a cost-effective approach to reducing transfusion-transmitted human immunodeficiency virus (HIV) infections. We performed a pilot case-control study to identify the risk factors for HIV infection and to develop an adapted donor history questionnaire (DHQ) for sub-Saharan Africa. STUDY DESIGN AND METHODS: We recruited 137 HIV-positive donors (cases) and 256 HIV-negative donors (controls) and gathered risk factor data using audio computer-assisted self-interview...

In the United States, chronic infection with the hepatitis C virus (HCV) affects an estimated 0.1-2% of the pediatric population, who are consequently at risk for major complications, including cirrhosis, hepatocellular carcinoma, and death. The current standard of treatment for chronic hepatitis C (CHC) in children is pegylated-interferon-alpha (PEG-IFN) in combination with ribavirin. PEG-IFN/ribavirin therapy is approved for children ages 3 and older; however, it is often held from use until adulthood because of its extensive list of potential side effects and high likelihood of causing adverse symptoms...

The ability of adolescents to access safe and effective new products for HIV prevention and treatment is optimised by adolescent licensure at the same time these products are approved and marketed for adults. Many adolescent product development programmes for HIV prevention or treatment products may proceed simultaneously with adult phase III development programmes. Appropriately implemented, this strategy is not expected to delay licensure as information regarding product efficacy can often be extrapolated from adults to adolescents, and pharmacokinetic properties of drugs in adolescents are expected to be similar to those in adults...

Sexually transmitted infections (STI) have a major impact on the reproductive health of women. Among the different etiological agents of STIs, Chlamydia trachomatis and Neisseria gonorrhoeae are the main bacterial pathogens that cause sexually transmitted infections in women. The aim of the study was to estimate the prevalence of genital chlamydial and gonococcal infection among women in the age group of 18-65 years from a community-based setting. A community-based cross-sectional study was performed using the archived urine samples (n=811) of women in the age group of 18-65 years for C...

In the cervico-vaginal micro-environment, lactobacilli are known to protect against genital infections and, amongst the host defence compounds, lactoferrin has recently acquired importance for its anti-microbial and anti-inflammatory properties. An abnormal genital micro-environment facilitates the acquisition of pathogens like Chlamydia trachomatis, the leading cause of bacterial sexually transmitted infections worldwide. The aim of our study is to investigate the effects of Lactobacillus crispatus, Lactobacillus brevis and bovine lactoferrin on chlamydial infection, in order to shed light on the complex interplay between host defence mechanisms and C...
