Positive and Negative Social Consequences of Participating in a Sexual-Network Study.

Assessment of risks and benefits of study participation is standard practice preceding the initiation of human subjects research. Although tracking adverse events during research participation is routine, collecting information from participants about what they perceive as benefits is less common. We longitudinally tracked social risks and benefits of participation among a cohort of 241 men who have sex with men participating in a sexual health study to improve participants' experiences and enhance understanding of participant motivations to enroll and attend follow-up. Of the participants who returned for at least one follow-up visit (n = 217, 90%), most (n = 185, 85%) reported positive consequences resulting from participation. Reporting of negative social consequences was rare, and all concerned a stigmatized reaction from someone learning about the participant's involvement in a sexual health study. Better identification of both positive and negative consequences resulting from research participation may improve how researchers design, recruit, and conduct research.

DEVELOPMENT AND EVALUATION OF A STANDARDIZED SYSTEM FOR THE ASSESSMENT OF LOCOMOTOR HEALTH IN ELEPHANTS UNDER HUMAN CARE.

Although lameness is a common problem in elephants (Asian elephant [Elephas maximus] and African elephants Loxodonta africana and Loxodonta cyclotis) under human care, there has not been a standardized lameness assessment system to date. This study developed and evaluated a standardized system for the assessment of locomotion in elephants under human care regardless of husbandry system. In total, 72 elephants out of a possible 73 in the United Kingdom and Ireland were filmed from behind, from in front, and from both sides. Using a questionnaire and a select panel of elephant specialists, a zoo veterinarian, and a locomotion expert, a numerical rating scoring (NRS) system was proposed. Locomotion was scored on a 4-point scale with numerical values 0-4 corresponding to specific criteria as follows: 0 = clinically sound, 1 = stiffness, 2 = abnormal tracking, and 4 = reluctance to bear weight. The intra- and interobserver repeatability of five veterinary surgeons using this system was determined and compared with a visual analog scale (VAS) expressed as a 100-mm line. Overall intraobserver reliability was moderate (Cohen's kappa [κ] = 0.676) and interobserver reliability was fair (κ = 0.37) for the presence of lameness. Interobserver agreement improved from the first scoring to second scoring from slight agreement to fair agreement for stiffness and reluctance to bear weight. Abnormal tracking had moderate intraobserver agreement for both scoring sessions. There were wide widths of agreement for the VAS interobserver (67 mm); however, they were narrower for the intraobserver (33 mm). The developed NRS can be used on freely moving elephants to evaluate elephant locomotion, regardless of husbandry methods, and has been shown to be more reliable than a VAS.

A systematic review of school-based student peer-led oral health interventions to promote the oral health of school children.

BACKGROUND: Poor oral health in children highlights the need for prevention and effective interventions. During late childhood and adolescence, peer relationships can play a vital role in adopting and maintaining positive health behaviours. AIM: To identify the oral health outcomes of school-based student peer-led delivery of oral health interventions. METHODS: A search strategy was developed, piloted, and run in four electronic databases: Medline via Ovid, Web of Science, CINAHL via EBSCO, and CENTRAL (Cochrane Central Register of Controlled Trials) using key concepts of peer, oral health and adolescent in the school context. Methodological quality was assessed using QuaDs quality assessment tool. All articles were independently screened by two researchers and data was analysed using narrative data synthesis. The PRISMA checklist complemented by aspects of the Synthesis Without Meta-analysis (SWiM) was used to report this systematic review. RESULTS: There were 7572 identified, 24 studies progressed to full-text review, ten studies met the eligibility criteria and were included in the review. Only six studies based their interventions on psychological & behavioural theory. Intervention delivered by peers showed improvements in both clinical and self-reported outcomes when compared to other delivery methods (e.g., professionals). Quality of included studies was reported according to QuaDs guidance. CONCLUSION: Peer-led interventions were more effective in improving oral health status and behaviours when compared to other modes of delivery. Future research should assess if a bi-directional impact of peer-led interventions can be seen. Specifically, if there is added value for school-based student peer-leader's including their own oral health knowledge, skills, attitude and preventative behaviours.

The emergence of SARS-CoV-2 lineages and associated saliva antibody responses among asymptomatic individuals in a large university community.

SARS-CoV-2 (CoV2) infected, asymptomatic individuals are an important contributor to COVID transmission. CoV2-specific immunoglobulin (Ig)-as generated by the immune system following infection or vaccination-has helped limit CoV2 transmission from asymptomatic individuals to susceptible populations (e.g. elderly). Here, we describe the relationships between COVID incidence and CoV2 lineage, viral load, saliva Ig levels (CoV2-specific IgM, IgA and IgG), and ACE2 binding inhibition capacity in asymptomatic individuals between January 2021 and May 2022. These data were generated as part of a large university COVID monitoring program in Ohio, United States of America, and demonstrate that COVID incidence among asymptomatic individuals occurred in waves which mirrored those in surrounding regions, with saliva CoV2 viral loads becoming progressively higher in our community until vaccine mandates were established. Among the unvaccinated, infection with each CoV2 lineage (pre-Omicron) resulted in saliva Spike-specific IgM, IgA, and IgG responses, the latter increasing significantly post-infection and being more pronounced than N-specific IgG responses. Vaccination resulted in significantly higher Spike-specific IgG levels compared to unvaccinated infected individuals, and uninfected vaccinees' saliva was more capable of inhibiting Spike function. Vaccinees with breakthrough Delta infections had Spike-specific IgG levels comparable to those of uninfected vaccinees; however, their ability to inhibit Spike binding was diminished. These data are consistent with COVID vaccines having achieved hoped-for effects in our community, including the generation of mucosal antibodies that inhibit Spike and lower community viral loads, and suggest breakthrough Delta infections were not due to an absence of vaccine-elicited Ig, but instead limited Spike binding activity in the face of high community viral loads.

Acquisition of Gonococcal AniA-NorB Pathway by the Neisseria meningitidis Urethritis Clade Confers Denitrifying and Microaerobic Respiration Advantages for Urogenital Adaptation.

Neisseria meningitidis historically has been an infrequent and sporadic cause of urethritis and other urogenital infections. However, a nonencapsulated meningococcal clade belonging to the hyperinvasive clonal complex 11.2 lineage has recently emerged and caused clusters of urethritis cases in the United States and other countries. One of the genetic signatures of the emerging N. meningitidis urethritis clade (NmUC) is a chromosomal gene conversion event resulting in the acquisition of the Neisseria gonorrhoeae denitrification apparatus-the N. gonorrhoeae alleles encoding the nitrite reductase AniA, the nitric oxide (NO) reductase NorB, and the intergenic promoter region. The biological importance of the N. gonorrhoeae AniA-NorB for adaptation of the NmUC to a new environmental niche is investigated herein. We found that oxygen consumption, nitrite utilization, and NO production were significantly altered by the conversion event, resulting in different denitrifying aerobic and microaerobic growth of the clade. Further, transcription of aniA and norB in NmUC isolates differed from canonical N. meningitidis, and important polymorphisms within the intergenic region, which influenced aniA promoter activity of the NmUC, were identified. The contributions of three known meningococcal regulators (NsrR, FNR, and NarQP) in controlling the denitrification pathway and endogenous NO metabolism were distinct. Overall, transcription of aniA was dampened relative to canonical N. meningitidis, and this correlated with the lower NO accumulation in the clade. Denitrification and microaerobic respiration were bolstered, and protection against host-derived NO was likely enhanced. The acquisition of the N. gonorrhoeae denitrification pathway by the NmUC supports the clade's adaptation and survival in a microaerobic urogenital environment.

Prenatal Neurological Diagnosis: Challenges in Neuroimaging, Prognostic Counseling, and Prediction of Neurodevelopmental Outcomes.

Prenatal diagnosis of fetal brain abnormalities is rapidly evolving with the advancement of neuroimaging techniques, thus adding value to prognostic counseling and perinatal management. However, challenges and uncertainties persist in prenatal counseling due to limitations of prenatal imaging, continued development and maturation of the brain structure, and the heterogeneity and paucity of outcome studies. This topical review of fetal neurological consultations highlights prenatally diagnosed brain abnormalities that challenged prognostic counseling and perinatal management. Representative cases across multiple centers that highlighted diagnostic challenges were selected. Charts were reviewed for neuroimaging, genetic evaluation, prenatal prognostic discussion, postnatal imaging and testing, and infant outcome. We present case studies with prenatal and postnatal information discussing prenatal testing, fetal MRI interpretation, and complexities in the prognostic counseling process. Advocating for large-scale multicenter studies and a national collaborative fetal neurological registry to help guide the ever-expanding world of prenatal diagnostics and prognostic counseling is critical to this field. Study of large-scale outcomes data from such a registry can better guide fetal neurological consultations and facilitate comprehensive multidisciplinary planning and program development for educational curriculum for fetal-neonatal neurology.

Antibiotic Susceptibility Profile for the US Neisseria meningitidis Urethritis Clade.

The US Neisseria meningitidis urethritis clade (US_NmUC) harbors gonococcal deoxyribonucleic acid alleles and causes gonorrhea-like urogenital tract disease. A large convenience sample of US_NmUC isolates (N = 122) collected between January 2015 and December 2019 in Columbus, Ohio demonstrated uniform susceptibility to antibiotics recommended for gonorrhea treatment and meningococcal chemoprophylaxis.

Assessing psychosocial costs: Ohio patients' experiences seeking abortion care.

OBJECTIVES: Existing research has not thoroughly characterized the psychosocial costs associated with seeking abortion care in restrictive states. Our study seeks to fill this gap by analyzing the accounts of Ohio abortion patients from 2018 to 2019. STUDY DESIGN: Using inductive and deductive approaches, we analyzed semi-structured in-depth qualitative interviews with 41 Ohio residents who obtained abortion care from one of three clinics in Ohio or Pennsylvania. RESULTS: Ohioans seeking abortion care often experienced fear of judgment, interpersonal strain, and stress as a result of efforts to overcome pre-Dobbs financial, geographic, and timing challenges. Those who needed financial assistance or traveled more than an hour generally reported greater exposure to psychosocial costs. CONCLUSIONS: Participants in this study incurred a complex set of psychosocial costs. Psychosocial costs often resulted from, or were exacerbated by, the financial, geographic, and time-sensitive burdens that patients experienced seeking care. IMPLICATIONS: The psychosocial costs incurred by patients seeking abortion care may be exacerbated in restrictive contexts, especially those who do not have access to insurance coverage for care. Psychosocial costs associated with care seeking are likely to increase as states implement more severe restrictions post-Dobbs. To fully understand abortion costs, researchers must examine costs comprehensively, including both financial and psychosocial costs.

Provider Mistrust and Telemedicine Abortion Care Preferences Among Patients in Ohio, West Virginia, and Kentucky.

Objectives: The convenience and privacy provided by telemedicine medication abortion may make this service preferable to patients who mistrust their abortion provider. We assessed associations between mistrust in the abortion provider and preferences for telemedicine abortion. Study Design: From April 2020 to April 2021, we surveyed patients seeking abortion in Ohio, West Virginia, and Kentucky. Using unconditional logistic regression models, we examined unadjusted and adjusted associations between mistrust in the abortion provider and preferences for telemedicine abortion among all participants, and among only participants undergoing medication abortion. Results: Of 1,218 patients who met inclusion criteria, 546 used medication abortion services. Just more than half (56%) of all participants and many (64%) of medication abortion participants preferred telemedicine services. Only 6% of medication abortion participants received telemedicine medication dispensing services. Only 1.4% of all participants and 1% of medication abortion participants mistrusted the abortion provider. Participants who mistrusted the abortion provider were somewhat more likely to prefer telemedicine abortion (unadjusted odds ratio [OR]: 2.5, 95% CI: 0.8-7.9; adjusted OR: 2.9, 95% CI: 0.9-9), and medication abortion participants who mistrusted the abortion provider were also somewhat more likely to prefer telemedicine abortion (unadjusted OR: 3.5, 95% CI: 0.4-28.9; adjusted OR: 5.0, 95% CI: 0.6-43), although these associations were not statistically significant. Conclusions: In three abortion-restrictive states, most patients expressed preferences for telemedicine abortion, but few accessed them. Provider mistrust was rare, but those experiencing mistrust trended toward preferring telemedicine services. Telemedicine may improve access to abortion services for patients experiencing medical mistrust.

Factors associated with never-use of long-acting reversible contraception among adult reproductive-aged women in Ohio.

BACKGROUND: The number of women using long-acting reversible contraception (LARC)-intrauterine devices (IUDs) and implants-is increasing and 14% of contraceptive users in the United States adopt LARC. We examined correlates of LARC never-use in a population-based survey of reproductive-aged women in Ohio. METHODS: We analyzed data from the 2018-19 Ohio Survey of Women. We examined the prevalence of LARC never-use and reasons for never-use among ever users of contraception (N = 2388). Using Poisson regression to generate prevalence ratios (PRs), we examined associations between selected correlates (demographic factors, healthcare access/quality measures, and religious/political views) and LARC never-use. RESULTS: Most Ohio women (74%) had never used LARC. Commonly reported reasons for not using an IUD or an implant were preferring a different method (46% and 45%, respectively), not wanting an object inside their body (45% and 43%), side effect concerns (39% and 33%), insertion/removal concerns (31% and 25%), and unfamiliarity (13% and 20%). Conservative political views (PR: 1.12, 95% confidence interval [CI]: 1.04-1.22), pro-life affiliation (PR: 1.11, 95% CI: 1.02-1.20), placing high importance on religion in daily life (PR: 1.15, 95% CI: 1.06-1.26), and being non-Hispanic white as compared to non-Hispanic Black (PR: 1.20, 95% CI: 1.02-1.41) were significantly associated with LARC never-use. Findings were generally similar for models analyzing IUD and implant never-use separately. CONCLUSIONS: Among ever-users of contraception, LARC never-use was associated with having conservative political views, being religious, and having a pro-life affiliation. Except for race/ethnicity, demographic and healthcare measures were not associated with LARC never-use among women in Ohio.

Factors Associated With Syphilis Transmission and Acquisition Among Men Who Have Sex With Men: Protocol for a Multisite Egocentric Network Study.

BACKGROUND: In the United States, the rates of primary and secondary syphilis have increased more rapidly among men who have sex with men (MSM) than among any other subpopulation. Rising syphilis rates among MSM reflect changes in both individual behaviors and the role of sexual networks (eg, persons linked directly or indirectly by sexual contact) in the spread of the infection. Decades of research examined how sexual networks influence sexually transmitted infections (STIs) among MSM; however, few longitudinal data sources focusing on syphilis have collected network characteristics. The Centers for Disease Control and Prevention, in collaboration with 3 sites, enrolled a prospective cohort of MSM in 3 US cities to longitudinally study sexual behaviors and STIs, including HIV, for up to 24 months. OBJECTIVE: The Network Epidemiology of Syphilis Transmission (NEST) study aimed to collect data on the factors related to syphilis transmission and acquisition among MSM. METHODS: The NEST study was a prospective cohort study that enrolled 748 MSM in Baltimore, Maryland; Chicago, Illinois; and Columbus, Ohio. NEST recruitment used a combination of convenience sampling, venue-based recruitment, and respondent-driven sampling approaches. At quarterly visits, participants completed a behavioral questionnaire and were tested for syphilis, HIV, gonorrhea, and chlamydia. The participants also provided a list of their sexual partners and described their 3 most recent partners in greater detail. RESULTS: The NEST participants were enrolled in the study from July 2018 to December 2021. At baseline, the mean age of the participants was 31.5 (SD 9.1) years. More than half (396/727. 54.5%) of the participants were non-Hispanic Black, 29.8% (217/727) were non-Hispanic White, and 8.8% (64/727) were Hispanic or Latino. Multiple recruitment strategies across the 3 study locations, including respondent-driven sampling, clinic referrals, flyers, and social media advertisements, strengthened NEST participation. Upon the completion of follow-up visits in March 2022, the mean number of visits per participant was 5.1 (SD 3.2; range 1-9) in Baltimore, 2.2 (SD 1.6; range 1-8) in Chicago, and 7.2 (SD 2.9; range 1-9) in Columbus. Using a community-based participatory research approach, site-specific staff were able to draw upon collaborations with local communities to address stigma concerning STIs, particularly syphilis, among potential NEST participants. Community-led efforts also provided a forum for staff to describe the NEST study objectives and plans for research dissemination to the target audience. Strategies to bolster data collection during the COVID-19 pandemic included telehealth visits (all sites) and adaptation to self-collection of STI specimens (Baltimore only). CONCLUSIONS: Data from NEST will be used to address important questions regarding individual and partnership-based sexual risk behaviors among MSM, with the goal of informing interventions to prevent syphilis in high-burden areas.

Changes in Sexual Behavior Over the COVID-19 Pandemic Among a Community-Based Cohort of Men Who Have Sex With Men in Columbus, Ohio.

BACKGROUND: The purpose was to assess COVID-19 beliefs and attitudes and examine COVID-19-related changes in sexual behavior of men who have sex with men during 3 time periods: April-July 2020 (T1), August-December 2020 (T2), January-May 2021 (T3). METHODS: Data were analyzed from 157 men who have sex with men in Ohio recruited to participate in a longitudinal multisite network study of syphilis epidemiology in 3 US cities: Columbus, Ohio; Baltimore, Maryland; and Chicago, Illinois. In April 2020, a COVID-19 module was appended to existing baseline and follow-up surveys to assess beliefs, attitudes, and changes in sexual behavior. Sample characteristics were summarized. Correlations between demographic variables (age, racial identity) and COVID-19 outcomes were examined. RESULTS: In response to COVID-19 social distancing restrictions and self-reported anxiety, some men limited sexual activity at T1, but the majority (n = 105 [67%]) continued to engage in sex. The number of men engaging in sex increased over time (T2: n = 124 [79%]; T3: n = 121 [77%]). At T1, men not in a relationship more frequently reported having less sex compared with prepandemic (n = 39 [57%]). By T3, men in a relationship more frequently reported less sex (n = 32 [54%]). Increased anxiety about sex and condom use was positively correlated with identifying as a man of color (P < 0.001). Most of the sample reported either starting or increasing online sexual activity during each time period. CONCLUSIONS: Future efforts to target sexual health during a pandemic or other health emergencies should prioritize men of color and address the unique perspective of both single and partnered men.

Housing Stability and Access to General Healthcare and Reproductive Healthcare Among Women in Ohio.

BACKGROUND: The relationship between housing instability and reproductive healthcare is understudied. We examined the association between housing insecurity and access and utilization of general healthcare, contraceptive healthcare, and abortion care. METHODS: Using data from a population-representative survey of adult reproductive-age Ohio women (N = 2,529), we assessed housing insecurity (not paying rent/mortgage on time in the past year). We examined associations between housing insecurity and the following outcomes: (1) not being able to access general healthcare in the past year; (2) experiencing delays or difficulties in accessing contraceptive healthcare in the past year; and (3) ever having an abortion. We used unadjusted and adjusted logistic regression models. We selected confounders a priori and included age, socioeconomic status, and healthcare status. RESULTS: Overall, 10.6% of Ohio women of adult reproductive age experienced housing insecurity. Approximately 27.5% of respondents were not able to access general healthcare and 10.4% experienced delays or difficulties in accessing contraceptive care. Compared to housing-secure respondents, housing-insecure women were less able to access general healthcare (adjusted odds ratio [aOR]:2.16; 95% confidence interval [CI]:1.45-3.23) and more likely to experience delays or difficulties when accessing contraceptive care (aOR:1.74; 95% CI:1.00-3.04). Insecure housing was not statistically associated with ever having an abortion (aOR:1.76; 95% CI:0.93-3.34). CONCLUSIONS: In this study, recent housing insecurity was associated with poorer access to general and contraceptive healthcare. Studies utilizing multidimensional measures of housing insecurity and other material insecurity measures are needed to further explore the relationship between material insecurity and access to general and contraceptive care.

Ohio survey data assessing perceptions of abortion safety.

OBJECTIVE: Despite overwhelming data supporting the safety of abortion care in the U.S., public perceptions of abortion safety vary widely. While evidence suggests that the public overestimates abortion risk, few studies have analyzed why people think abortion is safe or unsafe. STUDY DESIGN: Using data from the Ohio Survey of Women, a representative survey of women aged 18 to 44 years with a residential address in Ohio, we examined responses to 2 questions about abortion safety perceptions: the first asked respondents to rate abortion safety in Ohio, and the second asked respondents why they chose this rating of abortion safety. We analyzed these responses with inductive and deductive approaches. RESULTS: There were 2529 responses, of which 1368 (54%) provided a response to the open-ended question about abortion safety. From this subset, 529 gave open-ended responses indicating that they perceive abortion as safe, with 47% attributing this perception to the procedure being performed by a professional in a regulated environment. In contrast, 370 gave open-ended responses indicating that they perceive abortion as unsafe; the most common explanations referred to health risks (19%) and that safety depends on preexisting health conditions (19%). CONCLUSION: Many participants perceived abortion as safe because it is performed by professionals in a clinical environment or because of personal experiences with abortion. Those perceiving a lack of safety provided more varied responses, including that abortion was dangerous due to a detrimental effect on mental health or protesters at abortion clinics. IMPLICATIONS: We identified that women have a broad range of reasons for perceiving abortion as safe or unsafe. Providers should be aware of this diversity of abortion safety perceptions so that they can best engage with their patients.This updated characterization of pain experienced during an evidence-based medication abortion regimen may allow for better pain-related counseling, tailoring of opioid prescription practices, and improvement in patient satisfaction.

Evaluation of Urethrotropic-Clade Meningococcal Infection by Urine Metagenomic Shotgun Sequencing.

Urethral infections caused by an emerging nongroupable (NG) urethrotropic clade of Neisseria meningitidis were first reported in the United States in 2015 (the "U.S. NmNG urethritis clade"). Here, we evaluate for the presence of other urethral pathogens in men with U.S. NmNG urethritis clade infection. We evaluated 129 urine specimens collected from men at a sexual health clinic, including 33 from patients with culture-confirmed or suspected urethral N. meningitidis infection and 96 specimens in which nucleic acid amplification test detected Neisseria gonorrhoeae, Chlamydia trachomatis, both pathogens, or neither pathogen. N. meningitidis was detected first by real-time PCR, followed by metagenomic shotgun sequencing of 91 specimens to identify coinfections. N. meningitidis genomes were sequenced following selective whole-genome amplification when possible. Metagenomic sequencing detected N. meningitidis in 16 of 17 specimens from culture-confirmed N. meningitidis cases, with no coinfection by other conventional urethral pathogens. Metagenomic sequencing also detected N. meningitidis in three C. trachomatis-positive specimens, one specimen positive for both N. gonorrhoeae and C. trachomatis, and nine specimens with negative N. gonorrhoeae and C. trachomatis results, eight of which had suspected Neisseria infections. N. meningitidis from culture-confirmed N. meningitidis cases belonged to the U.S. NmNG urethritis clade, while N. meningitidis identified in other specimens belonged to multiple clonal complexes. Additional urethral pathogens were predominant in non-N. meningitidis specimens, including N. gonorrhoeae, C. trachomatis, Mycoplasma genitalium, Ureaplasma urealyticum, and herpes simplex virus 2. Coinfection with other conventional urethral pathogens is rare in men with culture-confirmed U.S. NmNG urethritis clade infection and points to the strong association of this clade with disease.

Prevalence of current and past COVID-19 in Ohio adults.

Purpose To estimate the prevalence of current and past COVID-19 in Ohio adults. Methods We used stratified, probability-proportionate-to-size cluster sampling. During July 2020, we enrolled 727 randomly-sampled adult English- and Spanish-speaking participants through a household survey. Participants provided nasopharyngeal swabs and blood samples to detect current and past COVID-19. We used Bayesian latent class models with multilevel regression and poststratification to calculate the adjusted prevalence of current and past COVID-19. We accounted for the potential effects of non-ignorable non-response bias. Results The estimated statewide prevalence of current COVID-19 was 0.9% (95% credible interval: 0.1%-2.0%), corresponding to ∼85,000 prevalent infections (95% credible interval: 6,300-177,000) in Ohio adults during the study period. The estimated statewide prevalence of past COVID-19 was 1.3% (95% credible interval: 0.2%-2.7%), corresponding to ∼118,000 Ohio adults (95% credible interval: 22,000-240,000). Estimates did not change meaningfully due to non-response bias. Conclusions Total COVID-19 cases in Ohio in July 2020 were approximately 3.5 times as high as diagnosed cases. The lack of broad COVID-19 screening in the United States early in the pandemic resulted in a paucity of population-representative prevalence data, limiting the ability to measure the effects of statewide control efforts.

Food insecurity and adverse pregnancy outcomes among rural Malawian women.

OBJECTIVE: To investigate whether food insecurity is associated with adverse pregnancy outcomes such as miscarriage, stillbirth, and neonatal mortality among women in rural Malawi. METHODS: We analyzed data from the baseline (July 2014 to February 2015) and follow-up (January 2018 to May 2018) waves of a longitudinal study of reproductive-age women in rural Malawi. We sampled women from villages from the catchment area of a community hospital in rural Lilongwe district of Malawi using stratified cluster sampling. We classified women as food secure or insecure at baseline. Using unadjusted and adjusted log-binomial models, we used baseline data to examine the cross-sectional association between food insecurity and ever experiencing an adverse pregnancy outcome. We used baseline and follow-up data to assess the longitudinal association between food insecurity and experiencing a new adverse pregnancy outcome during follow-up. In a subgroup analysis, we repeated the longitudinal analysis after restricting the sample to women who had no adverse pregnancy outcomes at baseline. RESULTS: We observed no significant cross-sectional association between baseline food insecurity and ever experiencing an adverse pregnancy outcome (adjusted prevalence ratio: 1.09; 95% confidence interval [CI]: 0.78-1.53). Baseline food insecurity was not associated with experiencing a new adverse pregnancy outcome during follow-up (adjusted risk ratio [aRR]: 1.14, 95% CI: 0.60-2.20) or in the subgroup analysis (aRR: 1.52, 95% CI: 0.78-2.96). CONCLUSIONS: While food insecurity is a critical issue, in this cohort of rural Malawian women, food insecurity was not associated with adverse pregnancy outcomes.

Infection With the US Neisseria meningitidis Urethritis Clade Does Not Lower Future Risk of Urethral Gonorrhea.

BACKGROUND: Cross-protective immunity between Neisseria meningitidis (Nm) and Neisseria gonorrhoeae (Ng) may inform gonococcal vaccine development. Meningococcal serogroup B (MenB) outer membrane vesicle (OMV) vaccines confer modest protection against gonorrhea. However, whether urethral Nm infection protects against gonorrhea is unknown. We examined gonorrhea risk among men with US Nm urethritis clade (US_NmUC) infections. METHODS: We conducted a retrospective cohort study of men with urethral US_NmUC (n = 128) between January 2015 and April 2018. Using diagnosis date as the baseline visit, we examined Ng status at return visits to compute urethral Ng risk. We compared these data to 3 referent populations: men with urethral Ng (n = 253), urethral chlamydia (Ct) (n = 251), and no urethral Ng or Ct (n = 255). We conducted sensitivity analyses to assess varied approaches to censoring, missing data, and anatomical site of infection. We also compared sequences of protein antigens in the OMV-based MenB-4C vaccine, US_NmUC, and Ng. RESULTS: Participants were primarily Black (65%) and heterosexual (82%). Over follow-up, 91 men acquired urethral Ng. Men with urethral US_NmUC had similar Ng risk to men with prior urethral Ng (adjusted hazard ratio [aHR]: 1.27; 95% CI: .65-2.48). Men with urethral US_NmUC had nonsignificantly increased Ng risk compared with men with urethral Ct (aHR: 1.51; 95% CI: .79-2.88), and significantly increased Ng risk compared with men without urethral Ng or Ct (aHR: 3.55; 95% CI: 1.27-9.91). Most of the protein antigens analyzed shared high sequence similarity. CONCLUSIONS: Urethral US_NmUC infection did not protect against gonorrhea despite substantial sequence similarities in shared protein antigens.

Estimating seroprevalence of SARS-CoV-2 in Ohio: A Bayesian multilevel poststratification approach with multiple diagnostic tests.

Globally, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected more than 59 million people and killed more than 1.39 million. Designing and monitoring interventions to slow and stop the spread of the virus require knowledge of how many people have been and are currently infected, where they live, and how they interact. The first step is an accurate assessment of the population prevalence of past infections. There are very few population-representative prevalence studies of SARS-CoV-2 infections, and only two states in the United States-Indiana and Connecticut-have reported probability-based sample surveys that characterize statewide prevalence of SARS-CoV-2. One of the difficulties is the fact that tests to detect and characterize SARS-CoV-2 coronavirus antibodies are new, are not well characterized, and generally function poorly. During July 2020, a survey representing all adults in the state of Ohio in the United States collected serum samples and information on protective behavior related to SARS-CoV-2 and coronavirus disease 2019 (COVID-19). Several features of the survey make it difficult to estimate past prevalence: 1) a low response rate; 2) a very low number of positive cases; and 3) the fact that multiple poor-quality serological tests were used to detect SARS-CoV-2 antibodies. We describe a Bayesian approach for analyzing the biomarker data that simultaneously addresses these challenges and characterizes the potential effect of selective response. The model does not require survey sample weights; accounts for multiple imperfect antibody test results; and characterizes uncertainty related to the sample survey and the multiple imperfect, potentially correlated tests.
