Online Discussions of Sexually Transmitted Infections During COVID-19: Insights From the Social Media Platform Reddit.

Background: With the onset of the COVID-19 pandemic, reported rates of chlamydia and gonorrhea dropped and remained low for several months of 2020 as compared with 2019. Additional data are needed to reveal causes of reported rate changes. Here, we analyze sexually transmitted infection (STI)-related conversations from the online-discussion platform Reddit to gain insight into the role of the pandemic on public experience of STIs in 2020.

Programme science: a route to effective coverage and population-level impact for HIV and sexually transmitted infection prevention.

Improvements in context-specific programming are essential to address HIV and other sexually transmitted and blood-borne infection epidemics globally. A programme science approach emphasises the need for context-specific evidence and knowledge, generated on an ongoing basis, to inform timely and appropriate programmatic decisions. We aim to accelerate and improve the use of embedded research, inquiry, and learning to optimise population-level impact of public health programmes and to introduce an effective programme coverage framework as one tool to facilitate this goal.

A Description of Telehealth Use Among Sexually Transmitted Infection Providers in the United States, 2021.

Background: Telehealth offers one approach to improving access to sexually transmitted infection (STI) prevention and care services. Therefore, we described recent telehealth use among those providing STI-related care and identified opportunities for improving STI service delivery.

Materials And Methods: Using the DocStyles Web-based, panel survey conducted by Porter Novelli from September 14 to November 10, 2021, 1500 healthcare providers were asked about their current telehealth usage, demographics, and practice characteristics, and compared STI providers (≥10% of time spent on STI care and prevention) to non-STI providers.

ATP11C promotes the differentiation of pre-B cells into immature B cells but does not affect their IL-7-dependent proliferation.

The P4-type ATPases are believed to function as flippases that contribute to the organization of the asymmetric aminophospholipid distribution on the plasma membranes of eukaryotes by their ability to internalize specific phospholipids from the outer leaflet to the inner leaflet. Despite the existence of 14 members of the P4-type ATPases in humans and 15 in mice, their roles in the immune system have not been fully understood. So far, ATP11C was shown to be important for B cells, and mice deficient for ATP11C had a developmental arrest at the pro-B to pre-B cell transition stage of B cell development.

Providing normative information increases intentions to accept a COVID-19 vaccine.

Despite the availability of multiple safe vaccines, vaccine hesitancy may present a challenge to successful control of the COVID-19 pandemic. As with many human behaviors, people's vaccine acceptance may be affected by their beliefs about whether others will accept a vaccine (i.e.

Identity effects in social media.

Identity cues appear ubiquitously alongside content in social media today. Some also suggest universal identification, with names and other cues, as a useful deterrent to harmful behaviours online. Unfortunately, we know little about the effects of identity cues on opinions and online behaviours.

A causal test of the strength of weak ties.

The authors analyzed data from multiple large-scale randomized experiments on LinkedIn's People You May Know algorithm, which recommends new connections to LinkedIn members, to test the extent to which weak ties increased job mobility in the world's largest professional social network. The experiments randomly varied the prevalence of weak ties in the networks of over 20 million people over a 5-year period, during which 2 billion new ties and 600,000 new jobs were created. The results provided experimental causal evidence supporting the strength of weak ties and suggested three revisions to the theory.

Global survey on COVID-19 beliefs, behaviours and norms.

Policy and communication responses to COVID-19 can benefit from better understanding of people's baseline and resulting beliefs, behaviours and norms. From July 2020 to March 2021, we fielded a global survey on these topics in 67 countries yielding over 2 million responses. This paper provides an overview of the motivation behind the survey design, details the sampling and weighting designed to make the results representative of populations of interest and presents some insights learned from the survey.

Reddit on PrEP: Posts About Pre-exposure Prophylaxis for HIV from Reddit Users, 2014-2019.

Social media forums provide a window into how gay, bisexual, and other men who have sex with men talk about pre-exposure prophylaxis for HIV prevention (PrEP) outside of research contexts. To examine information exchange about this important pillar of HIV prevention, discussions around PrEP were collected from the r/askgaybros subreddit of the social media site Reddit (2014-2019). Post titles and asks were qualitatively coded to identify themes describing the primary purpose of the post.

Exploring the dynamics of workplace typologies for sex workers in Eastern Ukraine.

We examine the typologies of workplaces for sex workers in Dnipro, Ukraine as part of the larger Dynamics Study, which explores the influence of conflict on sex work. We conducted a cross-sectional survey with 560 women from September 2017 to October 2018. The results of our study demonstrate a diverse sex work environment with heterogeneity across workplace typologies in terms of remuneration, workload, and safety.

Interdependent program evaluation: Geographic and social spillovers in COVID-19 closures and reopenings in the United States.

In an interconnected world, understanding policy spillovers is essential. We propose a program evaluation framework to measure policy spillover effects and apply that framework to study the governmental responses to COVID-19 in the United States. Our analysis suggests the presence of social spillovers.

Comparing the Ecological Niches of Chlamydial and Gonococcal Infections in Winnipeg, Canada: 2007-2016.

Background: Previous studies have shown substantial differences in geographic clustering of sexually transmitted infections (STI), such as chlamydia (CT) and gonorrhea (NG), conditional on epidemic phase. Chlamydia and NG have recently shown resurgent epidemiology in the northern hemisphere. This study describes the recent epidemiology of CT and NG in Winnipeg, Canada, combining traditional surveillance tools with place-based analyses, and comparing the ecological niches of CT and NG, in the context of their evolving epidemiology.

Programmatic mapping and size estimation of female sex workers, transgender sex workers and men who have sex with men in İstanbul and Ankara, Turkey.

Objectives: Despite a growing HIV threat, there is no definition and characterisation of key populations (KPs), who could be the major drivers of the epidemic in Turkey. We used programmatic mapping to identify locations where KPs congregate, estimate their numbers and understand their operational dynamics to develop appropriate HIV programme implementation strategies.

Methods: Female and transgender sex workers (FSWs and TGSWs), and men who have sex with men (MSM) were studied in İstanbul and Ankara.

Diverging trends in US male-female condom use by STI risk factors: a nationally representative study.

Objective: Condom use behaviours are proximal to recent STI increases in the USA, yet it remains unclear whether the use of condoms has changed over time among unmarried, non-cohabiting young men who have sex with women (MSW) and how this variability is influenced by STI risk factors.

Methods: To examine condom use over time among MSW aged 15-29, we used three cross-sectional surveys from the 2002, 2006-2010 and 2011-2017 National Survey of Family Growth. We estimated weighted percentages, adjusted prevalence ratios (APRs) and 95% confidence intervals (CI) to assess changes in condom use, stratified by whether MSW reported any STI risk factors in the past 12 months (ie, perceived partner non-monogamy, male-to-male sex, sex in exchange for money or drugs, sex partner who injects illicit drugs, or an HIV-positive sex partner).

Interdependence and the cost of uncoordinated responses to COVID-19.

Social distancing is the core policy response to coronavirus disease 2019 (COVID-19). But, as federal, state and local governments begin opening businesses and relaxing shelter-in-place orders worldwide, we lack quantitative evidence on how policies in one region affect mobility and social distancing in other regions and the consequences of uncoordinated regional policies adopted in the presence of such spillovers. To investigate this concern, we combined daily, county-level data on shelter-in-place policies with movement data from over 27 million mobile devices, social network connections among over 220 million Facebook users, daily temperature and precipitation data from 62,000 weather stations, and county-level census data on population demographics to estimate the geographic and social network spillovers created by regional policies across the United States.

Filling the gaps in the Peruvian care continuum for HIV-infected pregnant mothers: a case-control study in metropolitan Lima-Callao, Peru.

Mother-to-child transmission of HIV (MTCT) accounts for a significant proportion of new HIV infections in Peru. The purpose of this case-control study was to examine maternal and infant factors associated with MTCT in Peru from 2015 to 2016. For each biologically confirmed case infant, we randomly selected four birth year- and birth hospital-matched controls from five hospitals in Lima-Callao.
