Introduction HIV is a unique sexually transmitted infection (STI) that is greatly affected by other concomitant “classical” bacterial and viral STIs that cause genital ulcers and/or mucosal inflammation. STIs also serve as a marker for risky sexual behaviours. STIs increase infectiousness of people living with HIV by increasing the viral concentration in the genital tract, and by increasing the potential for HIV acquisition in people at risk for HIV. In addition, some STIs can increase blood HIV concentration and promote progression of disease. This review is designed to investigate the complex relationship between HIV and classical STIs. Discussion Treatment of STIs with appropriate antibiotics reduces HIV in blood, semen and female genital secretions. However, community‐based trials could not reliably reduce the spread of HIV by mass treatment of STIs. Introduction of antiretroviral agents for the treatment and prevention of HIV has led to renewed interest in the complex relationship between STIs and HIV. Antiretroviral treatment (ART) reduces the infectiousness of HIV and virtually eliminates the transmission of HIV in spite of concomitant or acquired STIs. However, while ART interrupts HIV transmission, it does not stop intermittent shedding of HIV in genital secretions. Such shedding of HIV is increased by STIs, although the viral copies are not likely replication competent or infectious. Pre‐exposure prophylaxis (PrEP) of HIV with the combination of tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) prevents HIV acquisition in spite of concomitant STIs. Conclusions STIs remain pandemic, and the availability of ART may have led to an increase in STIs, as fear of HIV has diminished. Classical STIs present a huge worldwide health burden that cannot be separated from HIV, and they deserve far more attention than they currently receive.

BACKGROUND: Changes to national guidelines for breast and cervical cancer screening have created confusion and controversy for women and their primary care providers. OBJECTIVE: To characterize women's primary health care provider attitudes towards screening and changes in practice in response to recent revisions in guidelines for breast and cervical cancer screening. DESIGN, SETTING, PARTICIPANTS: In 2014, we distributed a confidential web and mail survey to 668 women's health care providers affiliated with the four clinical care networks participating in the three PROSPR (Populationbased Research Optimizing Screening through Personalized Regimens) consortium breast cancer research centers (385 respondents; response rate 57.6 %). MAIN MEASURES:We assessed self-reported attitudes toward breast and cervical cancer screening, as well as practice changes in response to the most recent revisions of the U.S. Preventive Services Task Force (USPSTF) recommendations. KEY RESULTS: The majority of providers believed that mammography screening was effective for reducing cancer mortality among women ages 40-74 years, and that Papanicolaou (Pap) testing was very effective for women ages 21-64 years. While the USPSTF breast and cervical cancer screening recommendations were widely perceived by the respondents as influential, 75.7 and 41.2 % of providers (for mammography and cervical cancer screening, respectively) reported screening practices in excess of those recommended by USPSTF. Provider-reported barriers to concordance with guideline recommendations included: patient concerns (74 and 36 % for breast and cervical, respectively), provider disagreement with the recommendations (50 and 14 %), health system measurement of a provider's screening practices that use conflicting measurement criteria (40 and 21 %), concern about malpractice risk (33 and 11 %), and lack of time to discuss the benefits and harms with their patients (17 and 8 %). CONCLUSIONS: Primary care providers do not consistently follow recent USPSTF breast and cervical cancer screening recommendations, despite noting that these guidelines are influential.KEY WORDS: breast cancer screening; cervical cancer screening; provider practice patterns; primary care; clinical practice guidelines.

PCP beliefs about mammography effectiveness and screening recommendations are only modestly associated with use, suggesting other likely influences on patient participation in mammography.

High rates of non-nucleoside reverse transcriptase inhibitors (NNRTI) resistance was a key consideration in the WHO policies transitioning first-line regimens to include integrase inhibitors (dolutegravir [DTG]). However, recent data suggests a relationship between DTG and neural tube defects among women exposed during conception, giving providers and policymakers pause regarding the planned regimen changes. We examined HIV drug resistance among a cohort of 46 acutely infected persons in Malawi. Our data demonstrates high levels of transmitted resistance, 11% using standard resistance surveillance mutations and 20% when additional NNRTI polymorphisms that may affect treatment response are included. High resistance rates in this treatment-naïve patient population reinforces the critical nature of DTG-based options in the context of public-health driven treatment programs.

Introduction Sickle cell disease (SCD) is among the most common inherited hematologic diseases in sub‐Saharan Africa (SSA). Historically, hydroxyurea administration in SSA has been restricted due to limited region‐specific evidence for safety and efficacy. Methods We conducted a prospective observational cohort study of pediatric patients with SCD in Malawi. From January 2015 to November 2017, hydroxyurea at doses of 10–20 mg/kg/day was administered to children with clinically severe disease (targeted use policy). From December 2017 to July 2018, hydroxyurea was prescribed to all patients (universal use policy). Results Of 187 patients with SCD, seven (3.7%) died and 23 (12.3%) were lost to follow‐up. The majority (135, 72.2%) were prescribed hydroxyurea, 59 (43.7%) under the targeted use policy and 76 (56.3%) under the universal use policy. There were no documented severe toxicities. Under the targeted use policy, children with SCD demonstrated absolute decreases in the rates of hospitalization (−4.1 per 1000 person‐days; −7.2, −1.0; P = .004), fevers (−4.2 per 1000 person‐days; −7.2, −1.1; P = .002), transfusions (−2.3 per 1000 person‐days; 95% confidence interval: −4.9, 0.3; P = .06), and annual school absenteeism (−51.2 per person‐year; −60.1, −42.3; P < .0001) within 6 months of hydroxyurea commencement. Conclusion We successfully implemented universal administration of hydroxyurea to children with SCD at a tertiary hospital in Malawi. Similar to recently reported trials, hydroxyurea was safe and effective during routine programmatic experience, with clinical benefits particularly among high‐risk children. This highlights the importance of continued widespread scale‐up of hydroxyurea within SCD programs across SSA.
