Few evidence-based interventions have been widely adopted in common clinical settings, particularly for opioid-dependent people with HIV (PWH) seeking drug treatment. We developed a brief evidence-based intervention, Holistic Health for HIV (3H+), specifically for ease of implementation and integration within drug treatment settings. In this study, we compared 3H+ to the gold standard, Holistic Health Recovery Program (HHRP+) using a non-inferiority trial. Between 2012 and 2017, 106 participants were randomly assigned to either the brief 3H+ intervention or the gold standard HHRP+. HIV treatment (ART adherence, viral suppression) and risk behaviors (sharing injection equipment, condom use) were compared between the two arms at baseline, end-of-intervention (EOI-12 weeks) and at follow-up (24 weeks). Average treatment effect was calculated based on the difference-in-difference (DID) estimator and a non-parametric bootstrap was used to assess non-inferiority. At the 12-week EOI point, 3H+ was found to be non-inferior to HHRP+ with respect to multiple outcomes: percent sharing syringes and needles (DID:1.4, 95%CI [-18.6,21.5], p<0.01) and attainment of high ART adherence (DID: 9.7, 95%CI: [-13.1, 32.2], p = 0.04). At the 24-week EOI point, 3H+ was found to be non-inferior to HHRP+ with respect to percent sharing syringes and needles (DID: 8.9, [-10.1, 28.30], p = 0.04) and attainment of viral suppression (DID: 18.9, 95% CI:[-7.1, 42.0], p = 0.01). For other indicators, such as consistent condom use, the hypothesis test for non-inferiority was inconclusive at the 12-week EOI (DID: -20.2, 95%CI [-48.9–10.7], p = 0.51). For HIV treatment as prevention to be effective, PWH need to achieve viral suppression. In the absence of this success, they must reduce HIV risk behaviors. The finding that 3H+ was non-inferior to HHRP+ suggests that brief behavioral interventions can be deployed in real world settings to help more efficiently achieve Ending the HIV Epidemic goals.

Individuals involved with community supervision experience multi-level obstacles impacting health outcomes. This is a high-risk period for HIV acquisition due to potential reengagement in unprotected sex and/or unsafe injection drug practices. This study aimed to assess the congruence between actual and perceived HIV risk and the degree to which individual, social, and behavioral factors impact risk perception among individuals on community supervision. While all participants were clinically indicated for PrEP, most participants (81.5%) did not consider themselves at risk for HIV (69.5%) or were not sure of their risk (12.0%). Among those with no or unsure perceived risk, 94% engaged in sexual behaviors that put them at-risk of HIV. Perceived HIV risk was associated with sharing injection equipment (aPR = 1.8, 95% CI [1.02, 3.3]), identifying as a sexual minority (aPR = 2.3, 95% CI [1.3, 3.9]), and having sex with a partner living with HIV (aPR = 2.4, 95% CI [1.3, 4.3]). Having sex with a partner living with HIV was the only sexual risk behavior associated with a perceived risk of HIV. These findings indicate a substantial discrepancy between actual and perceived HIV risk, highlighting the need for targeted interventions to improve risk perception accuracy and enhance risk prevention among individuals on community supervision.

Aim Methodology Results Conclusions To evaluate the current status of endodontic education and assessment at an undergraduate/predoctoral level in dental schools worldwide.The current survey comprised a 50‐item online questionnaire related to undergraduate endodontic education. The project leaders emailed the survey's details to faculty members responsible for endodontic teaching at one dental school in every country to seek their willingness to participate in the survey. After the faculty members accepted, the survey details were sent to participants along with the survey link. Simple descriptive statistics were used to represent the data.Amongst the 44 faculty members from different countries who agreed to participate, 36 completed the survey. Endodontic training starts in 50% of dental schools from the third year of the curriculum. Each dental school employs a diverse range of educational methods. During pre‐clinical training, 19.4% of the participating dental schools used only natural teeth. Stainless‐steel hand instruments, syringe irrigation with a needle, resin‐based sealer and the cold lateral compaction technique are the most frequently used in pre‐clinical and clinical training. A significant percentage of dental institutions necessitate that students treat a predetermined quantity of canals or teeth throughout their pre‐clinical and clinical education. Dental institutions conduct formative, summative or a combination of the formative and summative throughout the clinical and pre‐clinical phases of endodontic training.According to the data collected from this survey, there are considerable variations in the curriculum for undergraduate/predoctoral endodontic programmes amongst the surveyed dental schools. Pre‐clinical and clinical education should integrate a larger array of modern tools and procedures. [ABSTRACT FROM AUTHOR]

The disease dynamics affect the human life. When one person is affected with a disease and if it is not treated well, it can weaken the immune system of the body. Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system, of the body which is the defense line against diseases. If it is not treated well then HIV progresses to its advanced stages and it is known as Acquired Immunodeficiency Syndrome (AIDS). HIV is typically a disease that can transferred from one person to another in several ways such as through blood, breastfeeding, sharing needles or syringes, and many others. So, the need of the hour is to consider such important disease dynamics and that will help mankind to save them from such severe disease. For the said purpose the reaction-diffusion HIV CD4 + T cell model with drug therapy under the stochastic environment is considered. The underlying model is numerically investigated with two time-efficient schemes and the effects of various parameters used in the model are analyzed and explained in a real-life scenario. Additionally, the obtained results will help the decision-makers to avoid such diseases. The random version of the HIV model is numerically investigated under the influence of time noise in It o ^ sense. The proposed stochastic backward Euler (SBE) scheme and proposed stochastic Implicit finite difference (SIFD) scheme are developed for the computational study of the underlying model. The consistency of the schemes is proven in the mean square sense and the given system of equations is compatible with both schemes. The stability analysis proves that both schemes and schemes are unconditionally stable. The given system of equations has two equilibria, one is disease-free equilibrium (DFE) and the other is endemic equilibrium. The simulations are drawn for the different values of the parameters. The proposed SBE scheme showed the convergent behavior towards the equilibria for the given values of the parameters but also showed negative behavior that is not biological. The proposed SIFD scheme showed better results as compared with the stochastic SBE scheme. This scheme has convergent and positive behavior towards the equilibria points for the given values of the parameters. The effect of various parameters is also analyzed. Simulations are drawn to evaluate the efficacy of the schemes. [ABSTRACT FROM AUTHOR]

Latinx people who inject drugs (PWID) are less likely to engage in injection equipment sharing, but are more vulnerable to injection drug use (IDU)-related morbidity and mortality than Whites. Identifying subgroups of Latinx PWID who do engage in equipment sharing and likely bear the brunt of this health burden is a priority. Ethnic disparities may reflect contextual drivers, including injection networks. Latinx PWID with low ethnic homophily (the proportion of individuals with the same ethnic background) may be more likely to share equipment due to forced distancing from health-protective ethnocultural resources and power imbalances within injection networks. The current study offers a framework and examines how associations between network ethnic homophily and injection equipment sharing differ among 74 Latinx and 170 non-Latinx White PWID in the Chicagoland area (N = 244). Latinx had less homophilous than non-Latinx Whites (p <.001). Ethnic homophily was protective for equipment sharing among Latinx (OR = 0.17, 95%CI [0.77, 0.04], p =.02), but not non-Latinx Whites (OR = 1.66, 95%CI [0.40, 6.93], p =.49). Our findings implicate the need for targeted cultured interventions that focus on Latinx PWID who are more vulnerable to morbidity and mortality, potentially due to less access to ethnic peers.

The ongoing hepatitis C virus (HCV) epidemic in the United States disproportionately affects rural people who inject drugs (PWID). This study explores the HCV risk environment in rural northern New England by examining PWID experiences and perceptions of HCV and injection equipment-sharing practices. We performed a thematic analysis on semi-structured interviews conducted with 21 adults with a history of injection drug use from rural New Hampshire, Vermont, and Massachusetts between April 2018 and August 2019. Salient themes included: (1) limited and varied access to sterile syringe sources; (2) syringe scarcity contributing to the use of informal syringe sources (e.g., secondary syringe exchange or syringe sellers who purchased syringes from out-of-state pharmacies); (3) syringe scarcity contributing to syringe sharing; (4) linkages among decisions about syringe sharing and perceptions of HCV risk, HCV status, and interpersonal trust; and (5) confusion and misconceptions about HCV, including difficulty learning one's HCV status, inadequate HCV education, and misconceptions regarding HCV transmission and treatment. Efforts to prevent and eliminate HCV among rural PWID should expand syringe access, increase awareness of HCV as a serious but preventable risk, and acknowledge social connections as potential influences on syringe access and syringe-sharing decisions.

Until recently, most syringe services programs (SSPs) in the United States operated in metropolitan areas. This study explores how SSP implementers at rural health departments in Kentucky secured support for SSP operations. In late 2020, we conducted in-depth, semi-structured interviews with 18 people involved with rural SSP implementation in Kentucky. Participants were asked to reflect on their experiences building support for SSP operations among rural health department staff and community members. Participants reported that attitudes and beliefs about SSP implementation among rural health department staff shifted quickly following engagement in educational activities and interaction with SSP clients. Participants explained that successful SSP implementation at rural health departments required sustained educational activities among community members and authorizing authorities. Future work should explore how rural communities may advocate for low-threshold and evidence-based policies that support the provision of harm reduction services. [ABSTRACT FROM AUTHOR]

Access to treatment and medication for opioid use disorder (MOUD) is essential in reducing opioid use and associated behavioral risks, such as syringe sharing among persons who inject drugs (PWID). Syringe sharing among PWID carries high risk of transmission of serious infections such as hepatitis C and HIV. MOUD resources, such as methadone provider clinics, however, are often unavailable to PWID due to barriers like long travel distance to the nearest methadone provider and the required frequency of clinic visits. The goal of this study is to examine the uncertainty in the effects of travel distance in initiating and continuing methadone treatment and how these interact with different spatial distributions of methadone providers to impact co-injection (syringe sharing) risks. A baseline scenario of spatial access was established using the existing locations of methadone providers in a geographical area of metropolitan Chicago, Illinois, USA. Next, different counterfactual scenarios redistributed the locations of methadone providers in this geographic area according to the densities of both the general adult population and according to the PWID population per zip code. We define different reasonable methadone access assumptions as the combinations of short, medium, and long travel distance preferences combined with three urban/suburban travel distance preference. Our modeling results show that when there is a low travel distance preference for accessing methadone providers, distributing providers near areas that have the greatest need (defined by density of PWID) is best at reducing syringe sharing behaviors. However, this strategy also decreases access across suburban locales, posing even greater difficulty in regions with fewer transit options and providers. As such, without an adequate number of providers to give equitable coverage across the region, spatial distribution cannot be optimized to provide equitable access to all PWID. Our study has important implications for increasing interest in methadone as a resurgent treatment for MOUD in the United States and for guiding policy toward improving access to MOUD among PWID. Author summary: Persons who inject drugs (PWID) such as heroin or other illicit substances are at increased risk of getting or transmitting HIV or hepatitis C (HCV) infection, because limited access to clean syringes and drug injection equipment means that PWID often share contaminated syringes. Public health interventions aimed at reducing injection drug use include medications for opioid use disorder (MOUD) that help to reduce cravings for opioids like heroin and fentanyl. However, resources like MOUD provider clinics are often unavailable to PWID due to factors such as the travel distance from home to clinic, frequent clinic visits, along with social phenomena such as degree of medical mistrust and stigma towards treatment. We use a computational simulation model of PWID social networks and drug use behaviors in Chicago, IL and suburbs to show how the geographic distribution of clinical providers of methadone, an MOUD, impacts the injection frequency of PWID. Our modeling results show that when PWID prefer a low travel distance to methadone providers, distributing providers near areas that have the greatest need is best at reducing syringe sharing behaviors. However, this strategy also decreases access across suburban locales, posing even greater difficulty in regions with fewer transit options and providers. [ABSTRACT FROM AUTHOR]

Introduction: Daily oral HIV pre‐exposure prophylaxis (PrEP) with tenofovir/emtricitabine (TDF/FTC) is recommended for people who inject drugs (PWID) but coverage is low. The real‐life effectiveness of PrEP among PWID is unknown as previous studies were conducted in controlled settings and mainly relied on self‐report. Analysis of PrEP metabolites—tenofovir diphosphate (TFVdp) and emtricitabine triphosphate (FTCtp)—offers an objective measure of adherence. Methods: To analyse longitudinal patterns of PrEP adherence among PWID in Ukraine, we used data from a community‐based implementation trial conducted in Kyiv between July 2020 and March 2021 to test the efficacy of SMS reminders to improve adherence. Among 199 enrolled participants, 156 (78.4%) were retained through 6 months. Based on TFVdp/FTCtp levels assessed at 3 and 6 months, we identified groups with various adherence patterns (adherent at ≥2 doses/week, improved, worsened, non‐adherent). Correlates of adherence were analysed using multinomial logistic regression. Results: Most participants (53.8%, n = 84/156) had no detectable metabolites at both assessments; 7.1% (n = 11/156) were consistently taking ≥2 doses/week; 1.3% (n = 2/156) were consistently taking ≥4 doses/week; 13.5% (n = 21/156) exhibited improved and 21.8% (n = 34/156) had worsened adherence at 6 compared to 3 months. "White coat compliance" (increased dosing prior to assessment) was common. Consistent adherence was associated with SMS reminders, younger age, employment, lower income, longer injection drug use duration, recent high‐risk injecting (receptive syringe sharing, using pre‐filled syringe, back‐ or front‐loading, container sharing), absence of overdose in the past 6 months, perceived HIV risk through sexual intercourse and higher PrEP self‐efficacy. Alcohol consumption was associated with inconsistent PrEP use. Groups with improved and worsened adherence did not differ. Conclusions: Daily oral PrEP may not achieve the desired effectiveness among PWID as a standalone intervention, calling for testing of alternative PrEP formulations and innovative integrated risk reduction strategies, especially in the context of HIV epidemics associated with injection drug use in eastern Europe and central Asia and the public health crisis in Ukraine caused by the war with Russia. SMS reminders may be effective among PWID who prioritize PrEP. Our findings offer practical guidance in identifying PWID who are likely to benefit from PrEP and those who need additional support.

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.

In 2016, the World Health Organization introduced global targets for the care and management of hepatitis C virus (HCV) infection to eliminate hepatitis C as a public health threat by 2030. Despite significant improvements in testing and treatment, in 2020 only 23% of all persons infected with HCV globally were diagnosed. We explore examples from global hepatitis C programs in Georgia, Rwanda, and Nigeria that have used decentralized and integrated models to increase access to HCV testing. Georgia established the world's first national hepatitis C elimination program in 2015. In 2022, 2.6 million people (80% of the adults) have been screened for antibodies for HCV infection, and 80 000 persons with HCV RNA detected were treated. To achieve these results, Georgia implemented HCV core antigen testing, utilization of point-of-care (POC) HCV RNA testing, and simplification of HCV viremia detection by qualitative HCV RNA testing. Rwanda was the first country in sub-Saharan Africa to commit to HCV elimination in 2018, and as of 2022 it has achieved its screening target of 7 million people and initiated approximately 60 000 patients on hepatitis C treatment by rapid decentralization and integration of HCV services. In Nigeria, the integrated near-POC testing approach in Nasarawa State has been effective in expanding access to HCV viremia testing and enabling the possibility of same-day testing and treatment initiation. Examples of decentralization and integration of HCV testing and linkage to care in Georgia, Rwanda, and Nigeria could help inform effective strategies to reach 2030 hepatitis C elimination goals in other countries.

Introduction: Understanding needle/syringe sharing is crucial for reducing hepatitis C virus (HCV) infection and reinfection. This study aimed to assess the prevalence and factors associated with needle/syringe sharing among people who inject drugs in Australia, including those previously receiving HCV treatment. Methods: The ETHOS Engage study was an observational cohort study which collected self‐reported survey data on demographic and drug use information from people who inject drugs attending drug treatment clinics and needle and syringe programs over two waves between May 2018 and June 2021. Logistic regression was used to identify factors associated with needle/syringe sharing. Results: Overall, 1555/2395 people enrolled in ETHOS Engage (65%) injected drugs in the past month. Among these, 432 (28%) reported needle/syringe sharing in the past month and 276 (18%) reported receptive sharing. Factors associated with receptive sharing included younger age (adjusted odds ratio [aOR] 1.72; 95% confidence interval [CI] 1.28–2.30), recent incarceration (aOR 2.04; 95% CI 1.40–2.94), more frequent injecting (≥daily vs. less than weekly; aOR 2.59; 95% CI 1.75–3.84) and unstable housing (aOR 1.78; 95% CI 1.26–2.52). Among 560 participants with prior HCV treatment, 87 (16%) reported receptive sharing with younger age (aOR 2.42; 95% CI 1.45–4.05) and daily or greater injection frequency (aOR 2.51; 95% CI 1.31–4.83) associated with receptive sharing. Discussion and Conclusions: Needle/syringe sharing was common among this population accessing harm reduction services. This study identifies high‐risk populations with needle/syringe sharing. Research is needed to optimise HCV treatment to ensure people with ongoing risk behaviours receive adequate harm reduction following treatment to prevent reinfection. [ABSTRACT FROM AUTHOR]

Long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP) could help overcome multilevel challenges to HIV prevention for people who inject drugs (PWID), including those in the binational San Diego-Tijuana metroplex. Yet, general PrEP awareness and interest in LAI-PrEP remain underexplored among PWID. From 2020 to 2021, 562 HIV-negative PWID in San Diego and Tijuana completed surveys assessing general PrEP awareness and interest in oral and LAI-PrEP. Modified Poisson regression examined factors associated with general PrEP awareness. Multinomial logistic regression assessed factors associated with interest in both oral and LAI-PrEP, oral PrEP only, LAI-PrEP only, or neither. General PrEP awareness was low (18%) and associated with experiencing unsheltered homelessness (adjusted prevalence ratio [APR] = 1.50, 95% confidence interval [CI]: 0.96–2.33), past 6-month fentanyl injection (APR = 1.53, 95% CI: 1.04–2.25), and transactional sex (APR = 1.71, 95% CI: 1.06–2.76). Interest in oral PrEP only was most common (44%), followed by LAI-PrEP only (25%) and neither (16%). Compared to the odds of being interested in LAI-PrEP only, the odds of being interested in oral PrEP only were lower among those who were stopped by police (AOR = 0.38, 95% CI: 0.22–0.65), reported past 6-month fentanyl injection (AOR = 0.33, 95% CI: 0.20–0.56), polydrug use (AOR = 0.48, 95% CI: 0.27–0.86), injecting multiple times daily (AOR = 0.26, 95% CI: 0.14–0.46), receptive syringe use (AOR = 0.30, 95% CI: 0.19–0.49), and higher perceived HIV risk (AOR = 0.24, 95% CI: 0.15–0.39). Interest in LAI-PrEP was more common among PWID reporting social and structural factors that could interfere with oral PrEP adherence, suggesting LAI-PrEP implementation could increase PrEP coverage among those most vulnerable to HIV.

Objective: We assessed types of cadaveric head and brain tissue specimen preparations that are used in a high throughput neurosurgical research laboratory to determine optimal preparation methods for neurosurgical anatomical research, education, and training. Methods: Cadaveric specimens (N = 112) prepared using different preservation and vascular injection methods were imaged, dissected, and graded by 11 neurosurgeons using a 21-point scale. We assessed the quality of tissue and preservation in both the anterior and posterior circulations. Tissue quality was evaluated using a 9-point magnetic resonance imaging (MRI) scale. Results: Formalin-fixed specimens yielded the highest scores for assessment (mean ± SD [17.0 ± 2.8]) vs. formalin-flushed (17.0 ± 3.6) and MRI (6.9 ± 2.0). Cadaver assessment and MRI scores were positively correlated (P < 0.001, R2 0.60). Analysis showed significant associations between cadaver assessment scores and specific variables: nonformalin fixation (β = −3.3), preservation within ≤72 h of death (β = 1.8), and MRI quality score (β = 0.7). Formalin-fixed specimens exhibited greater hardness than formalin-flushed and nonformalin-fixed specimens (P ≤ 0.006). Neurosurgeons preferred formalin-flushed specimens injected with colored latex. Conclusion: For better-quality specimens for neurosurgical education and training, formalin preservation within ≤72 h of death was preferable, as was injection with colored latex. Formalin-flushed specimens more closely resembled live brain parenchyma. Assessment scores were lower for preparation techniques performed > 72 h postmortem and for nonformalin preservation solutions. The positive correlation between cadaver assessment scores and our novel MRI score indicates that donation organizations and institutional buyers should incorporate MRI as a screening tool for the selection of high-quality specimens.

Background: Some of the most common complaints addressed by primary care physicians (PCPs) require manual procedures, such as lacerations repair, abscesses drainage, ingrown toenails removal, dry needling for myofascial pain syndrome, and Epley maneuver for treating benign paroxysmal positional vertigo (BPPV). The aim of this study was to describe the procedural skills workshops program for PCPs implemented in Maccabi Healthcare Services and to investigate how many PCPs have participated and used the skills since the program's inception in 2017. Methods: In this observational study, we followed all participants in courses from 2017 to 2021. We extracted all procedures performed during these years by PCPs who learned the skill in MHS. Results: During the study period, 620 PCPs participated in workshops for dry needling, soft-tissue and joint injections, BPPV treatment, minor surgical procedures, and spirometry. Most procedures performed were dry needling (average annual number 3,537) and minor surgical procedures (average annual number 361). The average annual use per physician was highest for dry needling (annual average use per physician who used the learned skill was 50.9), followed by soft tissue and joint injections (16.8), minor surgical procedures (14.8), and BPPV treatment (7.5). Conclusion: procedural skills workshops may expand PCPs' therapeutic arsenal, thus empowering PCPs and providing more comprehensive care for patients. Some manual skills, such as dry needling, soft tissue injections, and the Epley maneuver, were more likely to be used by participants than other skills, such as spirometry and soft tissue injections.

Drug use is common among people who live in prisons (PWLP) worldwide. This systematic review and meta-analysis aimed to summarize the prevalence of drug use among PWLP in Iran. We searched PubMed, Embase, Web of Science, Scopus, PsycINFO, as well as Farsi-language databases including Iran Psych Magiran, IranMedex, Scientific Information Database (SID), and Irandoc for studies published from January 2003 to January 2021. We included studies that reported the prevalence of drug use among PWLP. We performed a random-effects meta-analysis to pool prevalence estimates. Point estimates and 95% confidence intervals (CI) are reported. Among 1107 publications and reports screened, 16 studies reported the prevalence of drug use and were included. The pooled prevalence of lifetime non-injection drug use was 73.8% (95% CI 70.9, 76.6). The pooled prevalence of lifetime injection drug use was 16.0% (12.6, 19.7). Needle/syringe sharing among those with a lifetime injection drug use history was 14.0% (6.4, 24.0). Non-injection and injection drug use was found to be prevalent among PWLP in Iran. Continued evidence-based prevention, harm reduction, and treatment programs should address drug use among this population. [ABSTRACT FROM AUTHOR]

Background Sixty-eight percent of the nearly 3.5 million people living with hepatitis C virus (HCV) in the United States are people who inject drugs (PWID). Despite effective treatments, uptake remains low in PWID. We examined the social determinants of health (SDoH) that affect the HCV care cascade. Methods We conducted a secondary analysis of data from 720 PWID in a cluster-randomized trial. We recruited PWID from 12 drug-affected areas in Baltimore. Inclusion criteria were injection in the prior month or needle sharing in the past 6 months. Intake data consisted of a survey and HCV testing. Focusing on SDoH, we analyzed self-report of (1) awareness of HCV infection (in those with active or previously cured HCV) and (2) prior HCV treatment (in the aware subgroup). We used descriptive statistics and logistic regression for statistical analyses. Results The 342 participants were majority male and Black with a median age of 52 years. Women were more likely to be aware of their status but less likely to be treated. Having a primary care provider and HIV-positive status were associated with increased awareness and treatment. Unhoused people had 51% lower odds of HCV treatment. People who reported that other PWID had shared their HCV status with them had 2.3-fold higher odds of awareness of their own status. Conclusions Further study of gender disparities in HCV treatment access is needed. Increased social support was associated with higher odds of HCV treatment, suggesting an area for future interventions. Strategies to identify and address SDoH are needed to end HCV.

Introduction: People who inject drugs (PWID) are at increased risk for infectious disease transmission, including hepatitis C and HIV. Understanding trends in injection risk behaviors and syringe service program (SSP) use over time can help improve infectious disease prevention and other harm reduction services. Methods: Using National HIV Behavioral Surveillance System data from Baltimore, Maryland, we examined changes in receptive sharing of (1) syringes, (2) injection equipment, (3) syringes to divide drugs; and (4) receipt of syringes from SSPs among PWID from 2009 to 2018 (n = 518 in 2009, n = 638 in 2012, n = 586 in 2015, and n = 575 in 2018) using unadjusted and adjusted logistic models calculated across time for the total sample. Results: The conditional probability of receptive sharing of syringes and receipt of syringes from SSPs remained relatively stable, while receptive sharing of injection equipment and receptive sharing of syringes to divide drugs dropped substantially after 2009. White race and daily injection frequency were positively associated with sharing syringes and injection equipment and negatively associated with SSP use over time. In 2015, there was a notable shift such that women were twice as likely as men to receive syringes from SSPs and less likely than men to report the use of shared syringes or equipment. Conclusion: Findings indicate overall steady or decreasing trends in injection risk and steady trends in SSP usage over time, with some notable improvements among women and indications of shifting drug market patterns. Injection-related risk behaviors remain high among White PWID and may require targeted outreach and interventions. [ABSTRACT FROM AUTHOR]

ATS dependence in Malaysia is growing tremendously across multiracial Malaysian groups, increasing concerns among public health experts and the community. This study highlighted the chronicity of ATS dependence and factors associated with ATS use. Interviewer-administered questionnaires were administered using ASSIST 3.0. A total of N = 327 multiracial people who use ATS were enrolled in this study. The study findings show that 190/327 (58.1%) respondents were ATS dependent. Malays reported the highest number of ATS-dependent (55.8%), followed by Bajau (21.6%) and Kadazan-Dusun (16.8%) ethnic. Across all races, three factors were significantly associated with the ATS dependence: respondents who had a lifetime history of needle sharing aOR = 0.023 (95% CI: 0.003, 0.183) and a lifetime history of heroin use aOR = 0.192 (95% CI: 0.093, 0.396) were at a reduced odd of ATS dependent. Meanwhile, being married reduced the likelihood of becoming dependent on ATS with aOR = 0.378 (95% CI: 0.206, 0.693) compared to being single or divorced. This study revealed that the use of ATS among multiracial Malaysians is alarmingly high, including those in detention centers. Comprehensive harm reduction strategies are urgently needed to prevent the spreading of infectious diseases and other negative health consequences associated with ATS use. [ABSTRACT FROM AUTHOR]

The purpose of this analysis is to describe HIV tests and associated outcomes for Asian people reached by the Centers for Disease Control and Prevention (CDC) HIV testing program. We analyzed CDC-funded HIV tests among Asian individuals in the United States, Puerto Rico, and the U.S. Virgin Islands (2014-2020). Of the 415,560 tests, the positivity of new diagnoses was higher among males (0.49%, aPR = 7.64) than females (0.06%), and in the West (0.42%, aPR = 1.15) than in the South (0.25%). In non-health care settings, positivity was highest among men who have sex with men (MSM; 0.87%) and transgender people (0.46%). Linkage to HIV medical care among Asian people was 87.5%, and 70.7% were interviewed for partner services. Our findings suggest that improvements are crucial, particularly for Asian MSM, in linkage to care and interview for partner services. [ABSTRACT FROM AUTHOR]

Objectives. To describe the current financial health of syringe services programs (SSPs) in the United States and to assess the predictors of SSP budget levels and associations with delivery of public health interventions. Methods. We surveyed all known SSPs operating in the United States from February to June 2022 (n = 456), of which 68% responded (n = 311). We used general estimating equations to assess factors influencing SSP budget size and estimated the effects of budget size on multiple measures of SSP services. Results. The median SSP annual budget was $100 000 (interquartile range = $20 159‒$290 000). SSPs operating in urban counties and counties with higher levels of opioid overdose mortality had significantly higher budget levels, while SSPs located in counties with higher levels of Republican voting in 2020 had significantly lower budget levels. SSP budget levels were significantly and positively associated with syringe and naloxone distribution coverage. Conclusions. Current SSP funding levels do not meet minimum benchmarks. Increased funding would help SSPs meet community health needs. Public Health Implications. Federal, state, and local initiatives should prioritize sustained SSP funding to optimize their potential in addressing multiple public health crises.

Despite the availability of direct-acting antivirals that cure individuals infected with the hepatitis C virus (HCV), developing a vaccine is critically needed in achieving HCV elimination. HCV vaccine trials have been performed in populations with high incidence of new HCV infection such as people who inject drugs (PWID). Developing strategies of optimal recruitment of PWID for HCV vaccine trials could reduce sample size, follow-up costs and disparities in enrollment. We investigate trial recruitment informed by machine learning and evaluate a strategy for HCV vaccine trials termed PREDICTEE—Predictive Recruitment and Enrichment method balancing Demographics and Incidence for Clinical Trial Equity and Efficiency. PREDICTEE utilizes a survival analysis model applied to trial candidates, considering their demographic and injection characteristics to predict the candidate's probability of HCV infection during the trial. The decision to recruit considers both the candidate's predicted incidence and demographic characteristics such as age, sex, and race. We evaluated PREDICTEE using in silico methods, in which we first generated a synthetic candidate pool and their respective HCV infection events using HepCEP, a validated agent-based simulation model of HCV transmission among PWID in metropolitan Chicago. We then compared PREDICTEE to conventional recruitment of high-risk PWID who share drugs or injection equipment in terms of sample size and recruitment equity, with the latter measured by participation-to-prevalence ratio (PPR) across age, sex, and race. Comparing conventional recruitment to PREDICTEE found a reduction in sample size from 802 (95%: 642–1010) to 278 (95%: 264–294) with PREDICTEE, while also reducing screening requirements by 30%. Simultaneously, PPR increased from 0.475 (95%: 0.356–0.568) to 0.754 (95%: 0.685–0.834). Even when targeting a dissimilar maximally balanced population in which achieving recruitment equity would be more difficult, PREDICTEE is able to reduce sample size from 802 (95%: 642–1010) to 304 (95%: 288–322) while improving PPR to 0.807 (95%: 0.792–0.821). PREDICTEE presents a promising strategy for HCV clinical trial recruitment, achieving sample size reduction while improving recruitment equity. [ABSTRACT FROM AUTHOR]

Background: Geopolitical and socioeconomic challenges limit faculty development and clinical teaching in Palestine and many other developing countries. The first, and still only, Family Medicine (FM) residency program is a four-year program based out of An-Najah University in the West Bank. Training in primary care clinics occurs in the final two years and there are many challenges to adequate supervision in the clinical setting that were exacerbated during the pandemic. To improve the readiness for practice skills of 13 Palestinian FM residents a three-month tutorial program was organized in 2020. A nongovernmental organization (NGO) that has worked to support Family Medicine development in the region engaged experienced British and American General Practitioners trained as tutors to offer online tutorials. We examined the program as a case study to understand the factors that facilitated or impaired a positive virtual learning environment in a middle/low income country. Methods: The tutors and residents were divided into groups and met virtually between June and September 2020. Evaluations and session reports collected during the program, the text of an online chat, and responses to an online survey two years later were collected. Using thematic analysis techniques, we evaluated the value for the residents at the time and two years later and identified factors that facilitated or impaired a positive virtual learning environment. Results: Themes of knowledge, skills, attitudes, cultural disconnects, and tutorial logistics emerged. The group with the most stable tutor pairing, including one Arabic-speaker familiar with the context, was the most engaged. The all-female group formed a chat group to share real-time case questions during clinical practice and focused on skills (e.g. conducting a thorough medication review) and attitudes (e.g. open to sharing and discussing uncertainties). Other groups were less cohesive. Conclusions: Transnational tutorials that focused on clinical thinking and decision-making skills were most successful when the tutorial pair was stable, offered familiarity with the language and addressed cultural differences. Intrinsic factors such as lacking the motivation to participate and extrinsic factors such as unstable internet and rolling electric cuts, and clinical structures that made applying new skills challenging were more difficult to address but must be considered.

Background and aims: Network centrality, an indicator of an individual's importance and potential to drive behavioral change, is rarely used to select peer educators. Individual‐level predictors of network centrality might be useful to identify people who inject drugs (PWID) for potential roles as peer navigators or change agents in network‐based interventions in settings where sociometric data are unavailable. We assessed the relationship between network centrality and HIV prevention service engagement to determine whether centrally‐positioned PWID share measurable commonalities. Design: Observational study and survey using baseline data from a sociometric network cohort of PWID, enumerated using network software and biometric data (2017‐2020). Network ties corresponded to direct injection partnerships in the prior month. Setting: New Delhi, India. Participants: A total of 2512 PWID who were ≥18 years, provided written informed consent, and reported illicit injection drug use within the 24 months before study enrollment. Measurements Interviewer‐administered questionnaires measured demographics and substance use behaviors. Central versus peripheral network position was categorized using betweenness centrality 75th%ile. Logistic regression was used to estimate adjusted odds ratios (aOR) with 95% confidence intervals (95%CI) between network position and HIV testing, medication for opioid use disorder (MOUD), or syringe service use. Lasso models selected predictors of central network position among 20 covariates detailing demographic, biologic, and substance use information. Predictive accuracy was evaluated using model performance metrics. Findings Overall, median age was 26 years (interquartile range 22–34); 99% were male; 628 were classified as central. Compared with PWID at the periphery, central PWID were more likely to use MOUD (aOR: 1.59, 95%CI: 1.30–1.94) and syringe services (aOR: 2.91, 95%CI: 2.25, 3.76) in the prior six months. Findings for HIV testing were inconclusive (aOR: 1.30, 95%CI: 1.00–1.69). The lasso variable selector identified several predictors of network centrality: HIV and hepatitis C infection, number of PWID seen in the prior month, injecting heroin and buprenorphine (vs. heroin only) six months prior, sharing injection equipment six months prior, experiencing drug overdose in the past year, and moderate/severe depression (vs. none/mild). Average agreement between model‐predicted vs. observed values was 0.75; area under the receiver operator curve was 0.69. Conclusions: In a socioeconomic network of people who inject drugs (PWID) in New Delhi, India, there are common characteristics among individuals based on their network position (central vs. peripheral) but individual‐level predictors have only moderate predictive accuracy. Although central network members appear to be more likely to use HIV prevention services than peripheral network members, their potential as change agents may be limited by other factors that impede their ability to adopt or promote HIV prevention service use.

This article provides a review of methacrylate resin-based sealers used in endodontics, specifically in root canal procedures. The sealers have multiple functions, including sealing off voids and canals, creating a bond between filling material and the canal wall, and trapping bacteria. Resin-based sealers offer advantages such as reducing application time and potential errors, and different generations of these sealers have been developed. However, there are limitations and challenges associated with these sealers, such as polymerization shrinkage, microleakage, and cytotoxicity. The article discusses specific resin-based sealers, such as Hydron and EndoREZ, and their properties. Different types of resin-based sealers, including MetaSEAL, Epiphany, and Fiberfill, are mentioned, and the advantages and disadvantages of each are outlined. While resin-based sealers show promise, further research is needed to fully understand their clinical outcomes. [Extracted from the article]

Introduction: We developed a convolutional neural network (CNN) model to predict treatment outcomes of transforaminal epidural steroid injection (TFESI) for controlling cervical radicular pain due to cervical foraminal stenosis. Methods: We retrospectively recruited 293 patients with cervical TFESI due to cervical radicular pain caused by cervical foraminal stenosis. We obtained a single oblique cervical radiograph from each patient. We cut each oblique cervical radiograph image into a square shape, including the foramen that was targeted for TFESI, the intervertebral disc, the facet joint of the corresponding level with the targeted foramen, and the pedicles of the vertebral bodies just above and below the targeted foramen. Therefore, images including the targeted foramen and structures around the targeted foramen were used as input data. A favorable outcome was defined as a ≥ 50% reduction in the numeric rating scale (NRS) score at 2 months post TFESI compared to the pretreatment NRS score. A poor outcome was defined as a < 50% reduction in the NRS score at 2 months post TFESI vs. the pretreatment score. Results: The area under the curve of our developed model for predicting the treatment outcome of cervical TFESI in patients with cervical foraminal stenosis was 0.823. Conclusion: A CNN model trained using oblique cervical radiographs can be helpful in predicting treatment outcomes after cervical TFESI in patients with cervical foraminal stenosis. If the predictive accuracy is increased, we believe that the deep learning model using cervical radiographs as input data can be easily and widely used in clinics or hospitals.

The objective of this study was to explore HIV risk perceptions and to examine the factors associated with the perceptions of HIV risk among people who inject drugs in Saveh, Iran. In this cross-sectional survey, 272 people who inject drugs in Saveh were recruited using a convenience snowball sampling method between April 2020 and May 2021. Two classes of HIV risk perception (high versus low) were identified using logistic regression to determine factors associated with individual HIV risk perception. Study participants were categorized as having a low (n = 181, 66.5%) or high (n = 91, 33.5%) risk perception for becoming infected with HIV. The odds of categorizing as high risk for HIV was significantly greater in participants who reported: injecting their drugs more than 2 times per day (AOR = 2.4, p <.05); receptive syringe sharing (AOR = 3.1, p <.05) and as HIV positive (AOR = 3.9, p <.05). Participants who smoked heroin (AOR = 0.4, p <.05) and who had received any psychosocial intervention in the previous 3 months (AOR = 0.3, p <.05) were less likely to perceive being at high for HIV risk. Interventional programs should focus on improving the perceptions of people who inject drugs toward HIV risk and reducing their HIV risk behaviors through increased HIV self-assessments.

Background: The rise in injection drug use in the USA has led to an increase in injection site infections. We performed a national survey of people who use drugs to evaluate common drug use preparation, harm reduction practices, and experiences with injection site infections. Methods: A survey was disseminated to members of the Survey of Key Informants' Patients Program from 2021 to 2022 and distributed to patients 18 years or older newly entering one of 68 substance use disorder treatment programs across the USA with a primary diagnosis of an opioid use disorder. Participants were surveyed about practices when preparing and using drugs, along with self-reported infections and drug use complications. Results: 1289 participants responded to the survey. Sexually transmitted infections were common, with 37.6% reporting ever having had any sexually transmitted infection. Injection-associated infections had affected 63.4% of participants who had ever used injection drugs. Many respondents reported not seeking professional medical assistance for infection management, including 29% draining abscesses without seeking medical care and 22.8% obtaining antibiotics through non-healthcare sources. Non-sterile injection practices included sharing needles with others who were febrile or ill (18%), using needles previously used to drain wounds/abscesses (9.9%) for subsequent injection drug use, and licking needles (21.2%). Conclusion: Patients entering treatment for opioid use disorder reported a high burden of infectious diseases. A number of easily-modifiable high risk behaviors for developing injection-related infections were identified. Efforts are needed to disseminate targeted harm reduction education to PWID on how to reduce their risks for injection-related infections. [ABSTRACT FROM AUTHOR]

Aims: The primary aim of this study was to evaluate the impact of drug consumption rooms (DCRs) in France on injection equipment‐sharing, while the secondary aims focused upon their impact on access to hepatitis C virus (HCV) testing and opioid agonist treatment (OAT). Design: The COhort to identify Structural and INdividual factors associated with drug USe (COSINUS cohort) was a 12‐month longitudinal study of 665 people who inject drugs (PWID), conducted in Bordeaux, Marseille, Paris and Strasbourg. We used data from face‐to‐face interviews at enrolment and at 6‐month and 12‐month visits. Setting and participants: The participants were recruited in harm reduction programmes in Bordeaux and Marseille and in DCRs in Strasbourg and Paris. Participants were aged more than 18 years, French‐speaking and had injected substances the month before enrolment. Measurements We measured the impact of DCR exposure on injection equipment sharing, HCV testing and the use of medications for opioid use disorder, after adjustment for significant correlates. We used a two‐step Heckman mixed‐effects probit model, which allowed us to take into account the correlation of repeated measures and to control for potential bias due to non‐randomization between the two groups (DCR‐exposed versus DCR‐unexposed participants). Findings The difference of declared injection equipment sharing between PWID exposed to DCRs versus non‐exposed was 10% (1% for those exposed versus 11% for those non‐exposed, marginal effect = −0.10; 95% confidence interval = −0.18, −0.03); there was no impact of DCRs on HCV testing and OAT. Conclusions: In the French context, drug consumption rooms appear to have a positive impact on at‐risk practices for infectious diseases such as human immunodeficiency virus (HIV) and hepatitis C virus.

Stigma that people with HIV who inject drugs experience negatively impacts HIV and substance use care, but stigma’s association with sharing injection equipment is not known. This is a cross-sectional analysis of data from two studies of people with HIV reporting drug injection (N = 319) in St. Petersburg, Russia (September 2018-December 2020). We used logistic regression to examine associations between HIV stigma and substance use stigma scores (categorised into quartiles) and past 30-day equipment sharing, adjusting for demographic and clinical characteristics. Secondary analyses examined associations of arrest history and social support with sharing equipment. Almost half (48.6%) of participants reported sharing injection equipment. Among groups who did and did not share, mean HIV stigma (2.3 vs 2.2) and substance use stigma (32 vs 31) scores were similar. Adjusted analyses detected no significant associations between HIV stigma quartiles (global p-value = 0.85) or substance use stigma quartiles (global p-value = 0.51) and sharing equipment. Neither arrest history nor social support were significantly associated with sharing equipment. In this cohort, sharing injection equipment was common and did not vary based on stigma, arrest history, or social support. To reduce equipment sharing, investments in sterile injection equipment access in Russia should be prioritised over interventions to address stigma. [ABSTRACT FROM AUTHOR]

People in prison are at high risk of HCV given high injecting drug use prevalence. This study evaluated HCV incidence and associated injecting drug use characteristics in prison. The SToP‐C study enrolled people incarcerated in four Australian prisons. Participants were tested for HCV at enrolment and then every 3–6 months (October‐2014 to November‐2019). Participants eligible for this analysis included those at‐risk of HCV primary infection (anti‐HCV negative) or re‐infection (anti‐HCV positive, HCV RNA negative) with follow‐up assessment. A total of 1643 eligible participants were included in analyses (82% male; median age 33 years; 30% injected drugs in prison; 1818 person‐years of follow‐up). Overall HCV incidence was 6.11/100 person‐years (95%CI: 5.07–7.35), with higher rate of re‐infection (9.34/100 person‐years; 95%CI: 7.15–12.19) than primary infection (4.60/100 person‐years; 95%CI: 3.56–5.96). In total population (n = 1643), HCV risk was significantly higher among participants injecting drugs in prison [vs. no injecting; adjusted hazard ratio (aHR): 10.55, 95%CI: 5.88–18.92), and those who were released and re‐incarcerated during follow‐up (vs. remained incarcerated; aHR: 1.60, 95%CI: 1.03–2.49). Among participants who injected recently (during past month, n = 321), HCV risk was reduced among those receiving high‐dosage opioid agonist therapy (OAT), i.e. methadone ≥60 mg/day or buprenorphine ≥16 mg/day, (vs. no OAT, aHR: 0.11, 95%CI: 0.02–0.80) and increased among those sharing needles/syringes without consistent use of disinfectant to clean injecting equipment (vs. no sharing, HR: 4.60, 95%CI: 1.35–15.66). This study demonstrated high HCV transmission risk in prison, particularly among people injecting drugs. High‐dosage OAT was protective, but improved OAT coverage and needle/syringe programmes to reduce sharing injecting equipment are required. [ABSTRACT FROM AUTHOR]

Introduction: Identifying patterns of human immunodeficiency viruses (HIV) transmission and factors affecting it can help to prevent and control the disease. The present study aimed to identify the latent classes of HIV risk factors in Iran. Material and methods: This cross-sectional study was conducted among 32,168 HIV patients. We fitted latent class analysis by considering 11 indicators. Models with 2 to 5 classes were fitted, and the best-fitted model was chosen based on Acaik information critical (AIC), Bayesian information criterion (BIC), entropy, and interpretability of the results. Additionally, multinomial logistic regression model was applied to assess relationships between the covariates and latent class membership. Results: We identified 3 latent classes, including low-risk (41.35%), high-risk (50.28%), and moderaterisk (8.37%) classes. The moderate-risk class was most likely prison history (69.09%) and addiction (67.37%). The high-risk class included addiction (99.68%), injection drugs users (IDUs) (99.06%), prison history (86.27%), and sharing needles (79.64%). Older age and being single increased the odds of membership in high-risk class (OR: 1.021, 95% CI: 1.017-1.024%; OR: 1.34, 95% CI: 1.20-1.50%), respectively, while older age increased the odds of membership in classes of moderaterisk (OR: 1.028, 95% CI: 1.023-1.033%) compared with low-risk group (p < 0.05). The odds of membership in classes of high-risk (OR: 0.011, 95% CI: 0.010-0.013%) and moderate-risk (OR: 0.113, 95% CI: 0.098-0.131%) were significantly lower in women than in men compared with low-risk group (p < 0.05). Conclusions: Injection drugs users, drug addiction, sharing needles, and prison history are related to HIV infection in Iran. Moreover, older age, female gender, low education, and being single increase the odds of membership in high-risk classes. These findings highlight the need for preventive interventions and harm reduction programs for people at risk. [ABSTRACT FROM AUTHOR]

Correctional Service Canada implemented Prison Needle Exchange Programs (PNEPs) into federal penitentiaries in 2018 as a harm reduction measure to prevent needle sharing, drug overdose, and limit the spread of infectious disease. However, studies demonstrate how staff resistance hinders the growth of these programs within Canadian prisons. Drawing on interview data produced by 134 federally employed and relatively new correctional officers in Canada, the current study analyzes officers' levels of support and (more often) opposition to PNEP. Results indicate that, predominantly, staff opposition to PNEP is rooted in safety concerns, a perceived lack of evidence of PNEP's benefits, and fears the program is not promoting recovery and rehabilitation. By increasing the prevalence of needles in cells, officers report concern of overdose or potential weaponization of needles. Our study informs policy discussions around harm reduction measures in prisons to better promote institutional safety, public health, and nonstigmatized approaches to substance use.

Appropriate knowledge and expertise of parenteral injection is vital in the medical field. Hence we impart training on mannequins before the students practice on patients. This study was conducted to evaluate the skill exhibited by the students in parenteral injection skills, namely intravenous, intramuscular, intradermal and subcutaneous injections. The students were assessed for step based on the pre-validated check list created for Objective Structured Practical Examination. In this study, 16 % of the students failed to check the prescription order before starting the procedure. The name and the expiry date of the drug was not checked by 22 % of the students. Hundred percent of the students sterilized their hands. Loading of drug was done properly by 80 % of the students and 88 % of the students checked for air bubbles in the syringe and removed them properly. The site for injection was not sterilized by 26 percent of the students. Tourniquet was not applied by 19 percent of the students and 28 % of the students did not hold the bevel up during insertion for intravenous route. The steps where frequent faltering happened needs to be emphasized for them to perform better in a more efficient manner during the summative assessment as well as for future practice.

We assessed the prevalence and correlates of alcohol use among 870 people who inject drugs living with HIV in Kenya, with attention toward (1) sexual and injecting risk behaviors for HIV transmission and (2) HIV care engagement. We defined heavy alcohol use as > 14 drinks/week for men and > 7 drinks/week for women, moderate alcohol use as any lesser but non-zero amount, and any alcohol use as either moderate or heavy use. Approximately 39% of participants reported any alcohol use and 15% heavy use. In multivariate analysis, any alcohol use compared to no use was associated with needle sharing, > 3 new sex partners in the past 3 months, being unaware of HIV status, never enrolling in HIV care, and not being on ART (all p < 0.05). Heavy alcohol use as compared to no use was associated with needle sharing (aOR = 2.72; 95% CI 1.43, 5.13), injection equipment sharing (aOR = 1.80; 95% CI 1.00, 3.16), > 3 new sex partners in the past 3 months (aOR = 1.99; 95% CI 1.12, 3.49), and being unaware of HIV status (aOR = 2.77; 95% CI 1.46, 5.19). There was no association between any measure of alcohol use and unsuppressed viral load. Alcohol use among people who inject drugs living with HIV may carry elevated risk of HIV transmission mediated by sexual and injecting practices and is associated with lower engagement in multiple stages of the HIV care cascade.

Objective: To understand the extent to which adolescent awareness about anaemia and anaemia prevention can be changed by nutrition messages received at school. Design: Mixed‐methods pre–post intervention study. Setting: Three government schools in Bagalkot, Belagavi and Raichur districts of Karnataka, India. Population: Students of grade six and seven and teachers involved in implementing the intervention. Methods: An educational intervention was co‐developed by school teachers and nutrition experts using locally adapted resource materials that consisted of lectures, role play and practical demonstrations. Seven half‐hour educational sessions were delivered by school teachers over 7 weeks to 455 students. Pre‐ and post‐intervention tests measured changes in adolescents' knowledge about anaemia. Semi‐structured in‐depth interviews with teachers and focus groups with students explored their reactions to the intervention. Main outcome measures: Knowledge score related to anaemia. Results: The percentage of children with correct scores increased by 7.3–49.0 percentage points for the tested questions after implementation of the intervention. The mean knowledge score increased by 3.67 ± 0.17 (p < 0.01). During interviews, teachers and students highlighted high acceptance of the intervention and materials, an increase in awareness, a positive attitude towards changing behaviour around diet, an increase in the demand for iron and folic acid supplements and improved sharing of messages learned with peers and families. Challenges expressed included need for further training, time limitations and hesitancy in teaching about menstruation and pregnancy. Conclusions: Educational interventions carried out for adolescents by teachers in schools are effective in improving awareness and attitude related to anaemia and its prevention.

Introduction Medical simulation is a continuously expanding field. In surgical specialties, in particular, simulation can provide an alternative avenue for learning. The objective of this process improvement project was to evaluate the effectiveness and practicality of adding simulation-based training to our educational curriculum regarding common otologic procedures. Materials and Methods A low-cost, novel ear procedure simulator was designed and constructed from readily available clinic supplies. Participants were asked to fill out a pre-simulator survey to assess their own comfort and skill level before undergoing the simulation course. A pre-simulation PowerPoint training course was then administered to participants. The participants then underwent the simulation training course and were again asked to fill out a post-simulator training exercise survey to reassess their own comfort and skill level. Institutional review board approval was not required by Tripler Army Medical Center. Results A total of 15 participants consisting of junior residents in otolaryngology, third- and fourth-year medical students rotating on an otolaryngology clinical clerkship, and one physician assistant in otolaryngology were included in the study. There was a significant improvement in both provider comfort with the procedure and clinical performance of the procedure among participants after training on the simulation-based model. Conclusions Simulation-based training provides a safe, effective, and cost-friendly alternative to clinical medical education. Future studies are needed to address the wide-scale applicability of these results to other forms of surgical training. [ABSTRACT FROM AUTHOR]

This study aimed to field tested the "Avoid the Needle" (AtN) intervention to reduce transitions from non-injecting to injecting drug use in two different epidemiological settings. Respondent driven sampling was used to recruit current non-injecting drug users (NIDUs) in Tallinn, Estonia in 2018-19 and in New York City (NYC) in 2019-20. Both persons who had never injected and persons who had previously injected but not in the last 6 months were eligible; a structured interview was administered, a blood sample collected, and the intervention administered by trained interventionists. We recruited 19 non-injectors from Tallinn and 140 from NYC. Participants in Tallinn were younger and had begun using drugs at earlier ages than participants in NYC. The primary drugs used in Tallinn were amphetamine, fentanyl, and opioid analgesics, while in NYC they were heroin, cocaine, speedball, and fentanyl. Six-month follow-up data were obtained from 95% of participants in Tallinn. The study was interrupted by COVID-19 lockdown in NYC, but follow-up data were obtained from 59% of participants. There were minimal transitions to injecting: 1/18 in Tallinn and 0/83 in NYC. There were significant declines in the frequencies of using readily injectable drugs (fentanyl, amphetamine, heroin, cocaine) from baseline to follow-up in both sites (Cochran-Armitage tests for trend, χ2 = 21.3, p < 0.001 for New York City; and χ2 = 3.9, p = 0.048 for Tallinn). Reducing transitions into injecting is a potentially very important method for reducing HIV transmission and other harms of drug use. Further investigation and implementation of AtN type interventions is warranted. [ABSTRACT FROM AUTHOR]

Monitoring key populations' progress towards UNAIDS 90-90-90 targets is essential to achieving HIV/AIDS epidemic control. Using serial cross-sectional data, we evaluated changes in HIV care continuum among people who inject drugs(PWID) and men who have sex with men(MSM) in India. Cross-sectional baseline (2012/2013) and follow-up (2016/2017) samples were recruited using respondent-driven sampling across 21 cities. All participants were tested for HIV and RNA measured in HIV-positive participants. Linear regression was used to model temporal site-level changes in continuum indicators in MSM versus PWID. At baseline, we recruited 2,544 HIV-infected PWID and 1,086 HIV-infected MSM. At follow-up, we recruited 2,517 HIV-infected PWID and 1,763 HIV-infected MSM. At baseline, there were no significant differences in continuum indicators between MSM and PWID. At follow-up, compared to PWID, the proportion of MSM reaching each care continuum indicator—awareness of status, receipt of care, ART use, viral suppression—increased by 15-33 percentage points: 78% of MSM versus 49% of PWID were aware of their status (p < 0.01); 56% of MSM versus 32% of PWID were virologically suppressed (p = 0.05). MSM showed marked improvements across the care continuum, whereas PWID lagged and may require additional intervention. Differential improvement in HIV engagement may necessitate population-specific interventions and routine surveillance to facilitate HIV elimination. [ABSTRACT FROM AUTHOR]

Background: Due to COVID-19, face-to-face service activities in service-learning courses have become unfeasible. To address this challenge, this study aims to integrate project-based learning into medical education's service-learning curriculum. This study also seeks to evaluate the effectiveness of this instructional approach and identify factors that influence its success. Methods: A total of 135 first-year medical students enrolled in a mandatory 1-credit service-learning course were recruited. The course involved various service activities aligned with the needs of the local community. The students were organized into 12 groups, each working on different service-learning projects, such as raising health awareness or educating the public about specific diseases. Following the completion of the course, a questionnaire was distributed among the students to gather feedback on the course, and 122 (valid responses were collected, representing a response rate of 90.3%). Results: The results indicated that the project-based service-learning course significantly improved students' "interpersonal communication skills," their ability to "learn and grow from work," and their sense of "professionalism" (all p ≤ 0.037). Among the various aspects of service learning, the highest agreement was observed for "executing the project," followed by "group discussions and project formulation," "overall course review," "review of project outcomes," "outcome presentations," "teaching proposal writing and project brainstorming," "sharing of service-learning experiences by teachers," and "sharing of service-learning experiences by teaching assistants." Students also found certain factors to be beneficial in enhancing the learning effectiveness of service-learning courses, including "prize money for service-learning outcomes," "funding for service-learning activities," and "consultations from medical personnel" (all p ≤ 0.01). However, "course credit" and "photography software" did not show significant effects (both p > 0.05). The most preferred resources or activities for future service-learning courses were "course credit" and "face-to-face service-learning activities." Conclusions: The project-based learning method improved the learning effectiveness in service-learning courses. Students perceived that the number of course credits reflects the course value and plays a pivotal role in enhancing the learning effectiveness in service-learning courses. During the epidemic, students still expect to have face-to-face service activities in service-learning courses. Therefore, without the impact of the epidemic, service learning courses should return to face-to-face service activities. [ABSTRACT FROM AUTHOR]

Background: Data on recent human immunodeficiency virus (HIV), hepatitis C virus (HCV) and syphilis prevalence among drug users in the Southwest China are sparse despite the high burden of drug use. This study aims at assessing the prevalence trends and related factors of HIV, HCV and syphilis infection among different drug users in the China–Vietnam border area. Methods: A continuous cross-sectional survey was conducted among drug users from 2010 to 2020 in the China–Vietnam border area. Chi-square trend tests were used to assess the trend of HIV, HCV and syphilis prevalence and the proportion for drug type used by drug users. Multivariate logistic regression was used to identify associated factors of HIV, HCV and syphilis infection in different drug users. Results: In this study, a total of 28,951 drug users were included, of which 27,893 (96.45%) male, 15,660 (54.09%) aged 13–34 years, 24,543 (84.77%) heroin-only users, 2062 (7.12%) synthetic drug-only (SD-only) users and 2346 (8.10%) poly-drug users. From 2010 to 2020, the proportion of heroin-only users decreased from 87.79% to 75.46%, whereas SD-only users and poly-drug users increased from 5.16% to 16.03%, and from 7.05% to 8.52%, respectively. The prevalence of HIV, HCV, and syphilis during the study period declined from 12.76%, 60.37% and 5.72% to 4.35%, 53.29% and 4.53%, respectively, among heroin-only users and declined from 18.30%, 66.67% and 15.69% to 6.95%, 27.81% and 5.35%, respectively, among poly-drug users; however, the prevalence of HIV and HCV among SD-only users increased from 0.89% and 8.93% to 2.84% and 18.75%, respectively. Having ever injected drugs and needle sharing were common associated factors for both HIV and HCV infection among poly-drug users and heroin-only users. Aged ≥ 35 years old was an associated factor for HIV, HCV and syphilis infection among the SD-only users. Female drug users were at high risk of contracting syphilis among three different drug users. Conclusions: The prevalence of HIV, HCV and syphilis among heroin-only users and poly-drug users decreased during the study period. However, the prevalence of HIV and HCV among SD-only users increased. Comprehensive intervention strategies, particularly focusing on the SD-only users are needed in order to bring down the disease burden in this population in the China–Vietnam border areas.

Background: Discrimination by some healthcare providers toward people living with HIV/AIDS has been documented. Differences in cultural backgrounds make it harder for future doctors, who need a lot of knowledge and a positive attitude to treat patients. In conservative countries like Saudi Arabia, not enough is known about how much medical interns know about HIV and how they feel about people living with HIV/AIDS.Methods: From April to September 2021, this cross-sectional study use non-probability random sampling and utilized a self-administered questionnaire to collected the data from 346 medical interns who had graduated from five different medical schools.Results: Most of the subjects correctly identified the main transmission routes, such as unprotected sex (94.57%), blood and body fluid exchange (94.19%), and sharing needles or syringes (91.47%). But they did not know what the most common co-infections were for HIV patients or how to protect themselves after exposure. This paper showed that medical interns have some stigmatizing behaviors toward patients living with HIV, as 31.1% and 22.9% agreed, respectively, that they would feel more sympathetic toward people who get AIDS from blood transfusions compared to IV drug users (IDU).Conclusion: Medical interns also showed some positive attitudes, as more than half of the sample (56.2%) would not isolate beds for people living with HIV/AIDS. The study's conclusion is that HIV education and training programs should be added for medical interns, which might have a significant positive impact on their attitude. [ABSTRACT FROM AUTHOR]

Background: Black and Latino communities have been disproportionately impacted by coronavirus disease 2019 and we sought to understand perceptions and attitudes in four heavily impacted New Jersey counties to develop and evaluate engagement strategies to enhance access to testing. Objective: To establish a successful academic/community partnership team during a public health emergency by building upon longstanding relationships and using principles from community engaged research. Methods: We present a case study illustrating multiple levels of engagement, showing how we successfully aligned expectations, developed a commitment of cooperation, and implemented a research study, with community-based and health care organizations at the center of community engagement and recruitment. Lessons Learned: This paper describes successful approaches to relationship building including information sharing and feedback to foster reciprocity, diverse dissemination strategies to enhance engagement, and intergenerational interaction to ensure sustainability. Conclusions: This model demonstrates how academic/community partnerships can work together during public health emergencies to develop sustainable relationships. [ABSTRACT FROM AUTHOR]

Introduction: Few studies have investigated correlates of inconsistent condom use (ICU) among people who inject drugs (PWID). This study aimed to determine sociodemographic characteristics, type of drug use, risky behaviors, and service utilization associated with ICU among PWID. Methods: The study was cross-sectional, conducted between April 2020 and May 2021 in Saveh city (Iran). Sociodemographic, substance use, risky behaviors, and service use data were collected on 272 PWID interviewed face-to-face using a structured survey. The survey included a validated questionnaire with scales in which internal consistency reliability was estimated. ICU was assessed based on how often condoms were used with any sexual partners, including sex workers and casual partners, with four possible responses: always (100%), regularly (50–99%), occasionally (1–49%), and never. Data were produced using bivariate and multivariate regression analyses. Results: Participants mainly were male, were married, are more than 30 years old and had an income of 50 USA dollars per month. Compared to PWID without ICU, participants who were more likely to have ICU were those who used amphetamine in the past 3 months (adjusted odds ratio [AOR] = 2.07, P < 0.05) and had high HIV risk perception (AOR = 2.12, P < 0.05), while participants less likely to have ICU were those who were single, widowed, or separated (AOR = 0.50, P < 0.05) and using needle sharing program (NSP) (AOR = 0.37, P < 0.05). Conclusions: ICU can be improved among PWID by providing counselling and training on high-risk sexual behaviors, such as sexually transmitted infections (STI) and HIV risk perception, and by encouraging the use of contraceptives with sexual partners. Other impactful measures could address regular HIV testing and awareness, promoting condom self-efficacy and applying pre-exposure prophylaxis by NSP. Policy Implications: Preventive and harm reduction measures can substantially help minimize the risks of STI in this population. This is especially true for methamphetamine users who can highly benefit from condom distribution, needle and syringe exchange programs, and antagonist substitution treatments. As a result, risky sexual behavior and the incidence of STI might be considerably declined in this group. [ABSTRACT FROM AUTHOR]

Background: Since 2019, multiple HIV outbreaks occurred among people who inject drugs (PWID) in Minnesota. Syringe service programs (SSPs) are evidence-based programs that reduce the spread of HIV. We conducted an assessment of characteristics and HIV risk and prevention among clients of a delivery-based SSP near an HIV outbreak in rural, northern Minnesota. Methods: In the fall of 2021, we conducted a cross-sectional survey of clients of a mobile SSP based in Duluth, Minnesota. Survey topics included demographics, drug use, sexual behavior, HIV testing history, and HIV status. We conducted descriptive analyses and used univariate logistic regression to identify correlates of syringe sharing. The analysis was limited to PWID in the last six months. Results: A total of 125 people were surveyed; 77 (62%) were PWID in the last six months. Among these participants, 52% were female and 50% were homeless. Thirty-two percent reported sharing syringes and 45% reported sharing injecting equipment. Approximately one-half (49%) of participants had been tested for HIV in the past year, and none reported being HIV-positive. Individuals reported low condom usage (88% never used), and 23% of participants reported engaging in some form of transactional sex in the last six months. Incarceration in the last year was associated with sharing syringes (odds ratio = 1.4, 95% confidence interval 1.1–1.8). Conclusion: HIV risk was high among PWID receiving services at this SSP. These data highlight a rural SSP that is engaged with people at risk for HIV and needs additional support to expand harm reduction services. [ABSTRACT FROM AUTHOR]
