RESUMEN

In September 2022, deaths of pigs manifesting pox-like lesions caused by swinepox virus were reported in Tshuapa Province, Democratic Republic of the Congo. Two human mpox cases were found concurrently in the surrounding community. Specific diagnostics and robust sequencing are needed to characterize multiple poxviruses and prevent potential poxvirus transmission.

RESUMEN

BACKGROUND: Low immunization coverage rates in the Democratic Republic of Congo (DRC) have been reflective of challenges with vaccine access, support and delivery in the country. Motivated by measles and vaccine-derived polio virus (VDPV) outbreaks in 2016-17 and low vaccination rates, the provinces of Haut Lomami and Tanganyika were identified as pilot locations for an innovative approach focused on establishing a consortium of partners supporting local government. This approach was formalized through Memorandums of Understanding (MoUs) between the Bill and Melinda Gates Foundation and Provincial governments in 2018. A third province, Lualaba, established an MoU in 2021. MOU IMPLEMENTATION: These MoUs were 5-year partnerships designed to aid provinces in meeting four key objectives: 80 % immunization coverage, management/elimination of polio/cVDPV outbreaks, improvement of vaccine accessibility, and transfer of immunization service management to provincial leadership. OUTCOMES: During the MoU period, Haut-Lomami saw an increase in full immunization coverage, from 35.7 % (MICS 2018) to 88.9 % (VCS 2021-22), the highest in country. A sharp drop in percentage of zero-dose children was observed in the 3 provinces, confirming improved access to immunization services. Tanganyika saw initial improvement in full immunization coverage, followed by a drop in the VCS 2021-22 due to COVID-19 and healthcare worker strikes. Coverage improved in Tanganyika in the 2023 VCS. The 3 provinces increased their financial contributions to routine immunization and are now the top contributing provinces. While no cVDPV cases were recorded in 2020 and 2021, cVDPV1 and cVDPV2 outbreaks are afflicting the 3 provinces since 2022. CONCLUSIONS: Ultimately, the provincial MoUs were successful in bolstering provincial autonomy and capacity building with the biggest success being a drop in zero-dose children. While not all objectives have been met, the MoU approach served as an innovative program for key aspects of strengthening routine immunization in the DRC.

RESUMEN

BACKGROUND: The immunization system in the Democratic Republic of the Congo faces many challenges, including persistent large-scale outbreaks of polio, measles, and yellow fever; a large number of unvaccinated children for all antigens; minimal and delayed funding; and poor use of immunization data at all levels. In response, the Expanded Programme on Immunization within the Ministry of Health (MOH) collaborated with global partners to develop a revitalization strategy for the routine immunization (RI) system called the Mashako Plan. MASHAKO PLAN DESIGN AND DEVELOPMENT: The Mashako Plan aimed to increase full immunization coverage in children aged 12-23 months by 15 percentage points overall in 9 of 26 provinces within 18 months of implementation. In 2018, we conducted a diagnostic review and identified gaps in coordination, service delivery, vaccine availability, real-time monitoring, and evaluation as key areas for intervention to improve the RI system. Five interventions were then implemented in the 9 identified provinces. DISCUSSION: According to the 2020 vaccine coverage survey, full immunization coverage increased to 56.4%, and Penta3/DTP3 increased to 71.1% across the Mashako Plan provinces; the initial objective of the plan was reached and additional improvements in key service delivery indicators had been achieved. Increases in immunization sessions held per month, national stock of pentavalent vaccine, and supervision visits conducted demonstrate that simple, measurable changes at all levels can quickly improve immunization systems. Despite short-term improvements in all indicators tracked, challenges remain in vaccine availability, regular funding of immunization activities, systematic provision of immunization services, and ensuring long-term sustainability. CONCLUSIONS: Strong commitment of MOH staff combined with partner involvement enabled the improvement of the entire system. A simple set of interventions and indicators focused the energy of managers on discrete actions to improve outcomes. Further exploration of the results is necessary to determine the long-term impact and generate all-level engagement for sustainable success in all provinces.

RESUMEN

Enteric helminths form intimate physical connections with the intestinal epithelium, yet their ability to directly alter epithelial stem cell fate has not been resolved. Here we demonstrate that infection of mice with the parasite Heligmosomoides polygyrus bakeri (Hpb) reprograms the intestinal epithelium into a fetal-like state marked by the emergence of Clusterin-expressing revival stem cells (revSCs). Organoid-based studies using parasite-derived excretory-secretory products reveal that Hpb-mediated revSC generation occurs independently of host-derived immune signals and inhibits type 2 cytokine-driven differentiation of secretory epithelial lineages that promote their expulsion. Reciprocally, type 2 cytokine signals limit revSC differentiation and, consequently, Hpb fitness, indicating that helminths compete with their host for control of the intestinal stem cell compartment to promote continuation of their life cycle.

RESUMEN

BACKGROUND: Until recently, few carceral facilities offered medications for opioid use disorder (MOUD). Although more facilities are adopting MOUD, much remains to be learned about addressing implementation challenges related to expansion of MOUD in carceral settings and linkage to care upon re-entry. This is particularly important in jails, where individuals cycle rapidly in and out of these facilities, especially in jurisdictions beginning to implement bail reform laws (i.e., laws that remove the requirement to pay bail for most individuals). Increasing access to MOUD in these settings is a key unexplored challenge. METHODS: In this qualitative study, we interviewed staff from county jails across New Jersey, a state that has implemented state-wide efforts to increase capacity for MOUD treatment in jails. We analyzed themes related to current practices used to engage individuals in MOUD while in jail and upon re-entry; major challenges to delivering MOUD and re-entry services, particularly under bail reform conditions; and innovative strategies to facilitate delivery of these services. RESULTS: Jail staff from 11 New Jersey county jails participated in a baseline survey and an in-depth qualitative interview from January-September 2020. Responses revealed that practices for delivering MOUD varied substantially across jails. Primary challenges included jails' limited resources and highly regulated operations, the chaotic nature of short jail stays, and concerns regarding limited MOUD and resources in the community. Still, jail staff identified multiple facilitators and creative solutions for delivering MOUD in the face of these obstacles, including opportunities brought on by the COVID-19 pandemic. CONCLUSIONS: Despite challenges to the delivery of MOUD, states can make concerted and sustained efforts to support opioid addiction treatment in jails. Increased use of evidence-based clinical guidelines, greater investment in resources, and increased partnerships with health and social service providers can greatly improve reach of treatment and save lives.

RESUMEN

BACKGROUND: Four million individuals in the U.S. criminal-legal system are supervised in the community under probation or parole. Sentences to community supervision often mandate participation in substance use treatment. Yet evidence-based treatment with medication (i.e., methadone, buprenorphine, or naltrexone) is rarely offered to people under community supervision with opioid use disorder (OUD). This qualitative study explores the structural and organizational factors shaping OUD medication treatment use in community supervision. METHODS: We conducted in-depth interviews with 31 community supervision professionals. Thematic analysis characterized interview participants' perceptions of the key factors shaping use of OUD medications in community supervision. FINDINGS: Findings indicate that authorities making decisions about OUD treatment include community supervision agencies, treatment providers, judges and courts, and jails and prisons. Agencies with more rehabilitative cultural orientations are more forgiving of relapse and supportive of OUD medications. Punishment/enforcement orientations align with an emphasis on surveillance and drug testing, which can inhibit medication treatment and interrupt continuity of care. Community supervision agencies generally reported deference to the recommendations of substance use treatment providers regarding the details of treatment, including the use of medication. Given that most treatment providers do not offer OUD medication, community supervision agencies must develop a sophisticated understanding of the various services offered by local treatment providers to tailor referrals accordingly, a responsibility for which they may be inadequately trained. CONCLUSIONS: Efforts to improve engagement with medication treatment in U.S. community supervision settings could have a significant impact on reincarceration, morbidity, and mortality among individuals with OUD under supervision.

RESUMEN

AIMS: To identify implementation barriers and facilitators to the adoption and implementation of programs that provide opioid agonist treatments (OAT) with methadone and buprenorphine to treat opioid use disorder in jails and prisons in the United States. DESIGN: Qualitative analysis: semi-structured interviews were conducted and thematic analyses of transcripts and notes were performed using a hybrid inductive/deductive coding approach. SETTING: Jails and prisons in the United States. PARTICIPANTS: From August 2019 to January 2020, we conducted 20 key informant interviews with 35 individuals representing 19 carceral systems that both initiate and maintain OAT. MEASUREMENTS: Interviews covered four domains: (1) program adoption; (2) policy influence on implementation; (3) program structure; and (4) program outcomes. FINDINGS: Stigma among staff, particularly medical staff, challenged program adoption, but reduced over time as staff were exposed to the program. Regulations on OAT dispensation, such as licensing requirements and prescribing limits, were key challenges to program implementation and shaped program structure. Dispensing medication required significant staff, time and space. Facilities were further challenged to overcome stigma and concerns about diversion, as OAT medication is often treated as contraband in carceral settings. Some systems deviated from evidence-based treatment by limiting OAT dosage to low levels, requiring counseling for participation and requiring detoxification before medication initiation. Despite these challenges, early adopters felt strongly that other jails and prisons in the United States should provide OAT and that legislation and litigation may soon force OAT expansion in these carceral settings. CONCLUSIONS: Despite identifying regulatory and logistical challenges, early adopters of opioid agonist treatment (OAT) programs in US jails and prisons demonstrate that OAT programs can successfully be implemented in carceral settings with tailoring to the specific context.

RESUMEN

OBJECTIVES: To describe how the novel coronavirus (COVID-19) pandemic has affected opioid agonist treatment (OAT) programs in jails and prisons. METHODS: In May 2020, we conducted an online survey of 19 carceral systems that provided methadone and/or buprenorphine treatment for incarcerated populations before COVID-19. Eleven survey items examined challenges and changes to these programs as a result of the pandemic. Sixteen of 19 programs (84%) responded to the survey. RESULTS: Ten out of 16 systems reported downsizing their OAT programs. Seven of 16 systems made changes to medication dispensation processes. Half of systems report challenges implementing physical distancing (n = 8), and/or obtaining personal protective equipment (n = 8). In 13 out of 16 systems some OAT program participants were released early due to COVID-19 infection risk. CONCLUSIONS: Jails and prisons with existing OAT programs have curtailed their operations in the context of the COVID-19 pandemic. Given the robust evidence base around OAT for treating opioid use disorder and averting overdose deaths, guidance is needed on maintaining and ramping up medication access as carceral facilities grapple with implementing COVID-19 mitigation.
