Background
Male Tajik labour migrants who inject drugs in Russia are at high risk for HIV and other sexually transmitted infections. The “Migrants’ Approached Self-Learning Intervention in HIV/AIDS for Tajiks” (MASLIHAT) trained Tajik labour migrants who inject drugs in Moscow as peer educators (PEs) in delivering HIV prevention information and promoting risk-reduction norms and practices within their diaspora social networks while reducing their own HIV risk. Our earlier analysis of a cluster-randomized controlled trial testing the intervention’s effects found that MASLIHAT reduced condomless sex, condomless sex with female sex workers, and sex with multiple sexual partners. This analysis draws on data from this parent study to investigate if these observed changes in safer sex translated into fewer reported STIs over 12 months.
Methods
Male Tajik migrant workers in Moscow who inject drugs (
n
= 140) were recruited from construction worksites, local bazaars, and diaspora organizations serving labor migrants. Participants were assigned as PEs to either MASLIHAT or a comparison health education intervention. Each PE recruited two migrants who inject drugs from their social networks with whom to share what they learned during the 5 educational sessions of the arm to which they were assigned. All participants completed questionnaires at baseline and 3-month intervals for one year to assess their HIV/STI risk behaviour. Mixed effects robust Poisson regression analyses tested for possible differences between assignment conditions in self-reported STIs during 12 months of follow-up and the contribution of sexual risk behaviours to STI acquisition. We then tested the mediating effects of sexual behaviours during the first six months following the intervention on STIs reported at the 9 and 12-month follow-up.
Results
Participants in the MASLIHAT intervention were significantly less likely to report an STI during follow-up (IRR = 0.27). Condomless sex with a casual or commercial partner was significantly associated with STI acquisition (IRR = 2.30). Causal mediation analysis indicated that the intervention’s effect on reported STI was partially mediated by reductions among MASLIHAT participants in condomless sex with a casual or commercial partner.
Conclusions
The MASLIHAT peer-education intervention reduced reported STIs among Tajik labour migrants partly through reduced condomless sex with casual and commercial partners.

Introduction The “Migrants’ Approached Self‐Learning Intervention in HIV/AIDS for Tajiks” (MASLIHAT) recruits and trains Tajik labour migrants who inject drugs as peer educators (PEs) in delivering HIV prevention information and encouragement to adopt risk‐reduction norms and practices within their diaspora social networks while reducing their own HIV risk. Methods The MASLIHAT intervention was tested in Moscow in a cluster‐randomized controlled trial with 12 recruitment sites assigned to either the MASLIHAT intervention or an equal‐time peer‐educator training focused on other health conditions (TANSIHAT). From October 2021 to April 2022, 140 male Tajik migrants who inject drugs were recruited as PEs to attend the 5‐session MASLIHAT training or the TANSIHAT non‐HIV comparison condition. Each participant in both groups recruited two network members (NMs) who inject drugs with the intent to share with them the information and positive strategies for change they had learned (n = 280). All PEs and NMs (n = 420) participated in baseline and follow‐up interviews at 3‐month intervals for 1 year. All received HIV counselling and testing. Modified mixed effects Poisson regressions tested for group differences in injection practices, sexual risk behaviours and heavy alcohol use over time. Results At baseline, across both groups, 75% of participants reported receptive syringe sharing (RSS), 42% reported condomless sex and 20% reported binge drinking at least once a month. In contrast to TANSIHAT where HIV risk behaviours remained the same, significant intervention effects that were sustained over the 12 months were observed for receptive syringe and ancillary equipment sharing among both MASLIHAT PEs and NMs (p < 0.0001). Significant declines in the prevalence of sexual risk behaviours were also associated with the MASLIHAT intervention (p < 0.01), but not the comparison condition. Binge alcohol use was not affected in either condition; the MASLIHAT intervention had a transitory effect on drinking frequency that dissipated after 9 months. Conclusions The MASLIHAT peer‐education intervention proved highly effective in reducing HIV‐related injection risk behaviour, and moderately effective in reducing sexual risk behaviour among both PEs and NMs. Network‐based peer education is an important tool for HIV prevention among people who inject drugs, especially in environments that are not amenable to community‐based harm reduction.

The human immunodeficiency virus (HIV) epidemic in Eastern Europe and Central Asia continues to grow with most infections occurring in high-risk groups including people who inject drugs and their sexual partners. Labor migrants from this region who inject drugs while in Russia are at especially high HIV risk. Male Tajik migrant workers who inject drugs in Moscow (N = 420) were interviewed prior to a randomized trial of the Migrants’ Approached Self-Learning Intervention in HIV/AIDS (MASLIHAT) peer-education HIV-prevention intervention. Participants were interviewed about their sex and drug use behavior and tested for HIV and hepatitis C (HCV) prior to the intervention. Only 17% had ever been tested for HIV. Over half of the men reported injecting with a previously used syringe in the past month, and substantial proportions reported risky sexual behavior. Prevalence rates of HIV (6.8%) and HCV (2.9%) were elevated, although lower than expected when compared to estimates of prevalence among people who inject drugs at the national level in Tajikistan. Risk behavior in diaspora varied across the men’s regional area of origin in Tajikistan and occupation in Moscow, with HIV prevalence rates highest among those working at the bazaars. Evidence-based prevention approaches and messaging that specifically address the drug- and sex-related risk behavior of migrants with varying backgrounds are needed.

Telehealth Reduces Missed Appointments in Pediatric Patients with Tuberculosis Infection
2022
Pediatric patients with untreated tuberculosis infection (TBI), also called latent TBI, are at risk of progression to active TB disease. The primary aim of this study was to identify factors associated with higher rates of missed appointments and failure to complete therapy for pediatric patients with TBI. A secondary aim was to determine the impact of the COVID-19 pandemic and the rise of telehealth on TBI missed appointment rates. We first performed a retrospective chart review of 129 pediatric patients referred to the free Yale Pediatric Winchester Chest Tuberculosis Clinic from 2016–2019. Associations between demographic/clinical variables and missed appointments/failure to complete therapy were analyzed using univariate and bivariate chi-square tests. Language, lack of primary provider, and distance to clinic were the main contributors to missed appointments and poor treatment adherence. There was an association between the number of missed appointments and failure to complete treatment (p = 0.050). A second cohort of 29 patients was analyzed from January–December 2021 when telehealth was offered for follow-up appointments. Of these follow-up visits, 54% were conducted via telehealth, and the clinic’s missed appointment rate dropped significantly from 16.9% to 5.8% during this time frame (p = 0.037). These data demonstrate that telehealth is accepted as an alternative by patients for follow-up TBI visits.

Background
Village health workers (VHWs) in Bhutan play an all-encompassing role in supporting the health of their communities. Recent reports from the Bhutan Ministry of Health have indicated a sharp reduction in the number of working VHWs. As such, our work attempts to estimate the cost saved and the number of averted hospital admissions onto the Bhutanese healthcare system and the individuals who are served by these health workers.
Methods
We utilized a dataset from the Bhutan Ministry of Health which encompassed over 95% of all reported disease cases within the nation. We examined the impact that VHWs have on hospital admission rates for eight diseases of interest by using multiple multivariate logistic regression models. Our model allowed us to estimate the potential disease cases averted when the average number of VHWs per health center is increased by one unit. Lastly, we utilized the 2011 “A Costing of Healthcare Services in Bhutan” to estimate the cost saved attributed to VHWs.
Results
An average one unit increase of VHWs per health center is associated with a decrease in hospital and clinic admission for diarrhea, dysentery, wound care, depression/anxiety, dental caries, and skin infection, while a non-significant increase was observed for scabies and conjunctivitis. These findings translate to 4604 outpatient visits averted, with $28,637 saved, and 78 inpatient visits averted, with $10,711 saved. These values sum to a total of 4682 yearly averted admissions at health centers, with a total cost savings of $39,348 yearly. Additionally, we estimated a yearly savings of $13,348 in transportation costs and a total of $20,960 saved in wages to the community members that VHWs serve.
Conclusions
VHWs serve as a source of cost-savings for the Kingdom of Bhutan and also act as an economic buffer for more vulnerable communities. The cost-savings associated with these health workers is likely to become more pertinent as the nation begins to develop and healthcare costs increase. It is imperative that proper action be taken to retain these health workers as every VHW who leaves the program increases healthcare costs onto the Bhutanese government.

Evaluation of Connecticut medical providers’ concordance with 2017 IDSA/SHEA Clostridioides difficile treatment guidelines in New Haven County, 2018–2019
2021
To assess Connecticut medical providers' concordance (2018-2019) with the 2017 Clostridioides difficile infection (CDI) treatment update by the Infectious Disease Society of America (IDSA) and the Society for Healthcare Epidemiology of America (SHEA). The effect of guideline concordance on CDI recurrence risk was also assessed.
Prospective, population-based study.
New Haven County, Connecticut, from January 1, 2017, to December 31, 2019.
CDI incident case (no positive tests in the prior 8 weeks), not limited by care setting.
Using data from the Emerging Infections Program's CDI surveillance, severity and concordance were defined. Presence of megacolon and/or ileus defined fulminant disease; absence defined nonsevere/severe disease. Using 2017 treatment as baseline, 2018-2019 concordance was defined as receiving the recommended first-line antibiotic (ie, vancomycin or fidaxomicin for adult patients, vancomycin or metronidazole for pediatric patients) for exactly 10 days. For all analyses, significance was P < .05.
Among 990 cases, concordance increased from 24.8% in 2018 to 37.0% in 2019. First-line antibiotic concordance increased from 61.2% in 2018 to 79.9% in 2019. Recurrence risk was significantly associated with patients aged ≥65 years and was highest for those aged 75-84 years, but this factor was not significantly associated with concordance.
From 2018 through 2019, CDI treatment in New Haven County increasingly was concordant with the 2017 treatment update but remained low in 2019. Although concordance with treatment guidelines did not affect recurrence risk, close attention should be paid by medical providers to patients aged ≥65 years, specifically those aged 75-84 years because they are at an increased risk for recurrence.

Background
The interplay of human immunodeficiency virus (HIV) knowledge and self-perception of risk for HIV among people who inject drugs is complex and understudied, especially among temporary migrant workers who inject drugs (MWID) while in a host country. In Russia, Tajik migrants make up the largest proportion of Moscow’s foreign labor. Yet, HIV knowledge and self-perceived risk in association with sexual risk behavior among male Tajik MWID in Moscow remains unknown.
Objective
This research examines knowledge about HIV transmission, self-perception of HIV risk, and key psychosocial factors that possibly contribute to sexual risk behaviors among male Tajik labor MWID living in Moscow.
Methods
Structured interviews were conducted with 420 male Tajik labor MWID. Modified Poisson regression models investigated possible associations between major risk factors and HIV sexual risk behavior.
Results
Of the 420 MWID, 255 men (61%) reported sexual activity in the last 30 days. Level of HIV knowledge was not associated in either direction with condom use or risky sexual partnering, as measured by sex with multiple partners or female sex workers (FSW). Lower self-perceived HIV risk was associated with a greater likelihood of sex with multiple partners (aPR: 1.79, 95% CI: 1.34, 2.40) and FSW (aPR: 1.28, 95% CI: 1.04, 1.59), but was not associated with condom use. Police-enacted stigma was associated with sex with multiple partners (aPR: 1.22, 95% CI: 1.01, 1.49) and FSW (aPR: 1.32, 95% CI: 1.13, 1.54). While depression and lower levels of loneliness were associated with condomless sex (aPR: 1.14, 95% CI: 1.05, 1.24; aPR: 0.79, 95% CI: 0.68, 0.92, respectively), only depression was associated with condomless sex with FSW (aPR: 1.26, 95% CI: 1.03, 1.54).
Conclusions
HIV prevention programing for male Tajik MWID must go beyond solely educating about factors associated with HIV transmission to include increased awareness of personal risk based on engaging in these behaviors. Additionally, psychological services to counter depression and police-enacted stigma are needed.

Community Health Workers - statistics & numerical data
2021
Village health workers (VHWs) serve as an integral health resource for many resource limited nations, including the Kingdom of Bhutan. As such, we aimed to identify community perceptions as well as utilization rates and types with relation to VHWs based on the urban-rural divide. Our team conducted a randomized survey of 429 community members in 14 villages within the Western region of Bhutan. Our findings indicate VHWs in rural communities are requested for their services twice as much as their urban counterparts. More specifically, urban VHWs are utilized 2.5 times more for general community services, while rural VHWs are utilized more for accessing medications. Additionally, our research indicates a need to increase training of VHWs as well as overall program promotion relating to the specific services that VHWs can provide. These investigations indicate the importance of differentially allocating resources, programming, and training based on the urban-rural divide.
