Meningococcal Carriage Evaluation in Response to a Serogroup B Meningococcal Disease Outbreak and Mass Vaccination Campaign at a College—Rhode Island, 2015–2016

BackgroundnSerogroup B meningococcal disease caused 7 US university outbreaks during 2013-2016. Neisseria meningitidis can be transmitted via asymptomatic nasopharyngeal carriage. MenB-FHbp (factor H binding protein), a serogroup B meningococcal (MenB) vaccine, was used to control a college outbreak. We investigated MenB-FHbp impact on meningococcal carriage.nnnMethodsnFour cross-sectional surveys were conducted in conjunction with MenB-FHbp vaccination campaigns. Questionnaires and oropharyngeal swabs were collected from students. Specimens were evaluated using culture, slide agglutination, real-time polymerase chain reaction (rt-PCR), and whole genome sequencing. Adjusted prevalence ratios (aPRs) were calculated using generalized estimating equations.nnnResultsnDuring each survey, 20%-24% of participants carried any meningococcal bacteria and 4% carried serogroup B by rt-PCR. The outbreak strain (ST-9069) was not detected during the initial survey; 1 student carried ST-9069 in the second and third surveys. No carriage reduction was observed over time or with more MenB-FHbp doses. In total, 615 students participated in multiple surveys: 71% remained noncarriers, 8% cleared carriage, 15% remained carriers, and 7% acquired carriage. Ten students acquired serogroup B carriage: 3 after 1 MenB-FHbp dose, 4 after 2 doses, and 3 after 3 doses. Smoking (aPR, 1.3; 95% confidence interval [CI], 1.1-1.5) and male sex (aPR, 1.3; 95% CI, 1.1-1.5) were associated with increased meningococcal carriage.nnnConclusionsnCarriage prevalence on campus remained stable, suggesting MenB-FHbp does not rapidly reduce meningococcal carriage or prevent serogroup B carriage acquisition. This reinforces the need for high vaccination coverage to protect vaccinated individuals and chemoprophylaxis for close contacts during outbreaks.

Epidemiology of fentanyl-involved drug overdose deaths: A geospatial retrospective study in Rhode Island, USA

Background nWe conducted an epidemiological investigation of fentanyl and non-fentanyl overdose deaths in Rhode Island to inform overdose prevention efforts. nMethods nAll drug overdose deaths occurring in Rhode Island between January 1, 2014 and September 30, 2016 were included. Overdose circumstances and decedent characteristics were ascertained from medical examiner files. Toxicological reports provided quantification of fentanyl and metabolites. ArcGIS was used to map exact overdose locations. We compared fentanyl-associated with non-fentanyl overdose deaths using chi-square tests and Wilcoxon rank sum tests. To identify overdose clusters, we used the Getis-Ord Gi* statistic. nResults nA total of 778 overdose deaths were observed during the study period. In total, 358 (46.0%) were attributable to acute fentanyl intoxication, increasing from 84 (35.0%) in 2014 to 138 (55.6%) during the first nine months of 2016 (Mantel–Haenszel test for trend Pxa0<xa00.001). Compared to non-fentanyl overdoses, fentanyl overdose decedents were younger, more likely to have multiple drugs contribute to the death, and have evidence of injection drug use. The geospatial distribution of fentanyl and non-fentanyl involved deaths were similar. nConclusions nFindings suggest widespread penetration of fentanyl in the drug supply, impacting a diverse group of users. An immediate scale-up of harm reduction and overdose prevention interventions is needed.

Online Hookup Sites for Meeting Sexual Partners Among Men Who Have Sex with Men in Rhode Island, 2013: A Call for Public Health Action.

Frequent use of websites and mobile telephone applications (apps) by men who have sex with men (MSM) to meet sexual partners, commonly referred to as “hookup” sites, make them ideal platforms for HIV prevention messaging. This Rhode Island case study demonstrated widespread use of hookup sites among MSM recently diagnosed with HIV. We present the advertising prices and corporate social responsibility (CSR) programs of the top five sites used by newly diagnosed HIV-positive MSM to meet sexual partners: Grindr, Adam4Adam, Manhunt, Scruff, and Craigslist. Craigslist offered universal free advertising. Scruff offered free online advertising to selected nonprofit organizations. Grindr and Manhunt offered reduced, but widely varying, pricing for nonprofit advertisers. More than half (60%, 26/43) of newly diagnosed MSM reported meeting sexual partners online in the 12 months prior to their diagnosis. Opportunities for public health agencies to promote HIV-related health messaging on these sites were limited. Partnering with hookup sites to reach high-risk MSM for HIV prevention and treatment messaging is an important public health opportunity for reducing disease transmission risks in Rhode Island and across the United States.

Meningococcal carriage among a university student population-United States, 2015

OBJECTIVESnSeveral outbreaks of serogroup B meningococcal disease have occurred among university students in recent years. In the setting of high coverage of the quadrivalent meningococcal conjugate vaccine and prior to widespread use of serogroup B meningococcal vaccines among adolescents, we conducted surveys to characterize the prevalence and molecular characteristics of meningococcal carriage among university students.nnnMETHODSnTwo cross-sectional oropharyngeal carriage surveys were conducted among undergraduates at a Rhode Island university. Isolates were characterized using slide agglutination, real-time polymerase chain reaction (rt-PCR), and whole genome sequencing. Adjusted prevalence ratios and 95% confidence intervals were calculated using Poisson regression to determine risk factors for carriage.nnnRESULTSnA total of 1837 oropharyngeal specimens were obtained from 1478 unique participants. Overall carriage prevalence was 12.7-14.6% during the two survey rounds, with 1.8-2.6% for capsular genotype B, 0.9-1.0% for capsular genotypes C, W, or Y, and 9.9-10.8% for nongroupable strains by rt-PCR. Meningococcal carriage was associated with being male, smoking, party or club attendance, recent antibiotic use (inverse correlation), and recent respiratory infections.nnnCONCLUSIONSnIn this university setting, the majority of meningococcal carriage was due to nongroupable strains, followed by serogroup B. Further evaluation is needed to understand the dynamics of serogroup B carriage and disease among university students.

Development of a Statewide, Publicly Accessible Drug Overdose Surveillance and Information System

In response to Rhode Islands overdose epidemic, we developed a collaborative, statewide online dashboard to provide the public with timely overdose surveillance data. The Web site- www.PreventOverdoseRI.org (PORI)-offers user-friendly data visualizations, plain language education, and interactive resource maps. Development of the site has improved overdose data sharing and transparency in Rhode Island. Preliminary results suggest a successful site launch. Future research will evaluate the effectiveness of PORI in terms of informing strategic initiatives to reduce overdoses in affected communities.

Variations in pediatric HIV status disclosure between the orphanage and the community in Ethiopia

ABSTRACT Past studies on pediatric HIV disclosure have not investigated the variations across childcare settings. This study explored pediatric HIV disclosure for children living in the community with their birthparents or relatives and those living in orphanages in Addis Ababa, Ethiopia, to highlight the variations in reasons, processes and outcomes of disclosure across childcare settings. Semi-structured interviews were conducted with children and their caregivers attending an HIV clinic in Addis Ababa, Ethiopia. Among children living in orphanages, the proportion with disclosure was significantly higher (p < 0.001) and age at disclosure was younger (p = 0.09). Although the proportions of children with unplanned disclosure were similar in orphanages and the community, there were notable differences between children’s experiences. Children living in the community often found out their status alone through exposure to antiretroviral therapy advertisements in the media, unbeknownst to their caregivers and healthcare providers and suffered silently without any support. Orphans, on the other hand, experienced unplanned disclosure after the death of their birthparents and subsequently received significant emotional support. Healthcare professionals need to consider these variations with childcare settings in disclosure processes. Practices in orphanages may be important models for developing adequate support system for caregivers and children in the community.

Can Emergency Department, Hospital Discharge, and Death Data Be Used to Monitor Burden of Drug Overdose in Rhode Island?

Context: Drug overdoses are a growing public health problem in the United States. Rhode Island is also confronted with a serious epidemic of drug overdose deaths and ranks sixth worst in the United States for age-adjusted drug overdose death rate. Objective: To monitor trends of drug overdose-related emergency department (ED) visits, hospitalizations, and deaths and classify the drug overdoses by demographics, discharge status, intent, and specific drug involved to plan for health care resource allocation, mental health services, drug abuse treatment, prevention, and policies. Design: Cross-sectional study. Setting: The 2005-2014 ED, hospital discharge, and death data were used for this study. Main Outcome Measure: Age-adjusted rates were calculated by using age-specific Rhode Island 2010 standard population. Healthcare Cost and Utilization Project cost-to-charge ratios were used to convert total hospital charges to costs. The descriptive analysis was performed. Results: Hospitalizations generally represent the most severe cases; there are substantially fewer cases than are seen in the ED, and their characteristics are different from ED visits. More than half of the ED cases were an unintentional injury by drug overdose, but more than half of the hospital discharge data cases were a suicide/self-inflicted injury by drug overdose. There were typically much more females than males that result in a hospital admission. In Rhode Island, there were 249 drug overdose deaths in 2014. Drug overdose fatalities were more likely to be young, male, white, and those who reside in suburban regions. Implications: Nonfatal and fatal drug overdose data are important for understanding the scope, incidence, and breadth of this public health epidemic and can guide overdose intervention efforts. In Rhode Island, policy makers can use drug overdose data to target high-risk subpopulations to reduce overdose injuries and fatalities. The Rhode Island study can be shared with other states. Conclusions: Regardless of the type of drug, overdoses remain a public health crisis in Rhode Island. It is a dynamic epidemic and needs partnership among public health, behavioral health, public safety, clinic, pharmacy, and communities. The ability to track drug overdose in real time will be an essential tool to respond to the constantly evolving drug overdose epidemic in Rhode Island quickly and effectively.
