Factors associated with smoking and transitioning to nyaope injection amongst women in the City of Tshwane Municipality: A self-report by women

Background: Substance use disorder has emerged as a key health and social challenge in South Africa (SA). It is projected that about 15% of South African youth, especially young women are prone to engage in drug use and the prospects of coming into contact with nyaope, a highly addictive drug, are higher. Nyaope is mainly smoked, but the prevalence of injecting it is increasing in most regions. Aim: This study aimed to explore and describe the perception of women, who use nyaope, about the factors contributing to nyaope smoking and transitioning to injecting nyaope amongst women in the City of Tshwane Municipality (CoT), Gauteng. Setting: The research was conducted within Community Oriented Substance Use Programme sites across the CoT Municipality. Methods: Qualitative research methods were utilised to explore and describe the perceptions of the participants on factors contributing to the use of nyaope amongst women residing in the CoT. Data were collected through face-to-face interviews and thematically analysed. Results: Intimate partner influence (IPI), peer pressure, being misled by friends, weight loss, lack of effective coping mechanisms and counteracting other drugs contributed to women smoking nyaope. Additionally, a need for an intense high, IPI, influence by the social network, curiosity and cost-effectiveness contributed to women transitioning from smoking to injecting nyaope. Conclusion: The study has established factors contributing to smoking and transition to injecting nyaope as viewed by women residing in the CoT.

Point-of-care hepatitis C screening with direct access referral to improve linkage to care among halfway house residents: a pilot randomised study

INTRODUCTION@#Linkage to care among individuals with substance misuse remains a barrier to the elimination of the hepatitis C virus (HCV). We aimed to determine whether point-of-care (PoC) education, screening and staging for liver disease with direct access to hospitals would improve linkage to care among this group. @*METHODS@#All participants were offered PoC education and HCV screening. HCV-positive participants were randomised to standard care (controls) or direct access, which provided a direct pathway to hospitals. Linkage to care was determined by reviewing electronic medical records. Linkage of care cascade was defined as attendance at the specialist clinic, confirmation of viraemia by HCV RNA testing, discussion about HCV treatment and initiation of treatment. @*RESULTS@#351 halfway house residents were screened. The overall HCV prevalence was 30.5% (n = 107), with 69 residents in the control group and 38 in the direct access group. The direct access group had a significantly higher percentage of cases linked to specialist review for confirmatory RNA testing (63.2% vs. 40.6%, p = 0.025), HCV treatment discussion (p = 0.009) and treatment initiation (p = 0.01) compared to the controls. Overall, only 12.6% (n = 13) had treatment initiation during follow-up. PoC HCV screening with direct access referral had significantly higher linkage to HCV treatment initiation (adjusted odds ratio 9.13, p = 0.005) in multivariate analysis. @*CONCLUSION@#PoC HCV screening with direct access improves linkage to care and simplifies the HCV care cascade, leading to improved treatment uptake. PoC education, screening, diagnosis and treatment may be an effective strategy to achieving HCV micro-elimination in this population.

Prevalence of substance abuse, assessment of socio-economic and demo-graphic determinants of commercial motorcyclists in Katsina State Nigeria

Background: Substance abuse has been reported to have adversely affected socio-economic determinants of states and nations. Substance abuse is the use of tobacco, alcohol, illegal or prescription drugs and other substances in ways contrary to the overall health of the individual. It has been grossly under-reported and undermined in Katsina State, Nigeria. Identification and early intervention of associated risk factors had greater impact than later intervention by changing individual's life pathway from problems and towards positive behaviors. Objectives: To determine the prevalence of substance abuse amongst motorcyclists and associated socio-economic characteristics in Katsina State, Nigeria, a cross sectional study approach was commissioned. Methodology: Convenient sampling using a mobile Open Data collection tool (ODK) application was used to collect and collate field data. Data was analyzed using SPSS®. Strength of significance within categorical variables were reported and accepted at P≤0.05. Results:Kola nut (53%) and Marijuana (1%) were identified to have the highest and lowest prevalence respectively (P>0.05) across Jibia and Katsina Local Government Areas the (2 LGAs) in Nigeria where the study was carried out. Almost all types of psychoactive substances were available in Nigeria due to their spill over into the streets from drug traffickers who use Nigeria as a conduit to transport drugs from South East-Asia (the Golden,South America to Europe and North America [12]. Conclusion: With an overall substance abuse prevalence of 19%, it was concluded that substance abuse was endemic in the state and hence public health education must be used to check this societal ill

Introducción: El uso irracional de antimicrobianos es un problema de salud. En el Cardiocentro Pediátrico William Soler existe una amplia utilización de ellos, sin embargo, no se conoce el comportamiento del consumo de este grupo farmacológico en la institución. Objetivo: Describir el consumo de antimicrobianos seleccionados en la institución en el periodo 2011-2015. Método: Estudio descriptivo, longitudinal del tipo estudio de utilización de medicamentos de consumo de 11 antimicrobianos, de uso restringido y elevado costo (cefepime, meropenem, levofloxacina oral y parenteral, linezolida, teicoplanina, vancomicina, colistina, aztreonam y amoxicilina/sulbactam oral y parenteral). El consumo en unidades físicas se obtuvo a partir de las tarjetas de estiba del almacén de medicamentos de la farmacia intrahospitalaria. Para el cálculo se utilizó la fórmula establecida por la Organización Mundial de la Salud, expresado en dosis diaria definida/100 camas/día (DDD/100 camas/día). Resultados: Se observó un incremento de 7,28 DDD/100 camas/día, los años 2013 y 2015 se mostraron como los de mayor consumo. Los fármacos más consumidos fueron el meropenem con un incremento de 2,71 DDD/100 camas/día; el cefepime con un incremento de 1,68 DDD/100 camas/día y la linezolida con un aumento de 1,15 DDD/100 camas/día. La terapia 1 y la sala 1A mostraron los mayores valores de consumo. Conclusiones: Los antimicrobianos han reducido de manera importante la amenaza de enfermedades infecciosas y son una herramienta indispensable en el tratamiento de los pacientes en los hospitales. El consumo de antimicrobianos seleccionados en el Cardiocentro Pediátrico William Soler, considerados de alto costo y utilización restringida, evidencia una tendencia al incremento, lo cual muestra la necesidad de desarrollar un programa de optimización de uso de estos medicamentos en la institución(AU)

Introduction: The irrational use of antimicrobials is a health problem. In William Soler Pediatric Cardiocenter there is a wide use of them; however, the behavior of the consumption of this pharmacological group in the institution is not known. Objective: To describe the consumption of selected antimicrobials in the institution in the period 2011-2015. Method: Descriptive, longitudinal study of the use of medicines for the consumption of 11 antimicrobials, of restricted use and high cost (cefepime, meropenem, oral and parenteral levofloxacin, linezolid, teicoplanin, vancomycin, colistin, aztreonam and amoxicillin / oral and parenteral sulbactam). The average consumption in physical units was obtained from the stowage cards of the drug store of the in-hospital pharmacy. For the calculation, the formula established by the World Health Organization was used and this is expressed in a defined daily dose / 100 beds / day (DDD / 100 beds / day). Results: An increase of 7.28 DDD / 100 beds / day was observed; the years 2013 and 2015 were shown as those with the highest consumption. The most consumed drugs were meropenem with an increase of 2.71 DD / 100 beds / day; cefepime with an increase of 1.68 DD / 100 beds / day; and linezolid with an increase of 1.15 DDD / 100 beds / day. Therapy room 1 and room 1A showed the highest consumption values. Conclusions: Antimicrobials have reduced in a crucial way the threat that infectious diseases represent, and they are also an indispensable tool in the treatment of patients in hospitals. The consumption of selected antimicrobials considered of high cost and restricted use in William Soler Pediatric Cardiocenter shows a tendency to increase, which shows the need to develop a program to optimize the use of antimicrobials in the institution(AU)

Prevalence of hepatitis C virus infection and the IL28B genotype polymorphism among blood donors and high-risk populations

INTRODUCTION@#To study the prevalence of hepatitis C virus (HCV) infection in blood donor (BD), haemodialysis (HD) and intravenous drug user (IVDU) populations in Singapore and assess the IL28B polymorphism if HCV positive.@*METHODS@#The BD population were healthy volunteers, the HD population were patients who were on haemodialysis for at least six months of follow-up between January 2009 and December 2014. IVDU population was from inmates at halfway houses who consented.@*RESULTS@#Between 2011 and 2014, of 161,658 individuals who underwent screening prior to blood donation, 95 (0.059%) were positive for HCV. Of the 42 sera available, common genotypes (GTs) were GT-3 (47.6%) and GT-1 (31.0%). Of 1,575 HD patients, 2.2% were anti-HCV positive. The HCV GT distribution was HCV GT-1 (32.4%), HCV GT-3 (20.5%) and GT-6 (8.8%). 83 halfway house inmates were screened. Of the 47 IVDUs, 36.2% were anti-HCV positive with predominant GT-3 (%). IL28B polymorphism was noted to be CC predominantly 85.3%.@*CONCLUSION@#Prevalence of HCV infection has decreased in both the BD and HD populations. However, it remains high in the IVDU population. GT-1 remains the most common in the HD population; however, GT-3 infection is now more common among the BD population in Singapore. IL28B - CC is the predominant variant among the HCV-infected individuals in Singapore.

Adherence to antiretroviral therapy in HIV-positive, male intravenous drug users in Pakistan

Background: Human immunodeficiency virus [HIV] is fifth leading cause of mortality and disability among infectious diseases worldwide. HIV burden is increasing annually and compliance with antiretroviral therapy [ART] is low among intravenous drug users, especially in developing countries.

Aim: To determine the adherence level to ART among HIV-positive intravenous drug users in Karachi Pakistan.

Methods: A cross-sectional study was conducted in 2015. A pretested questionnaire was administered to 375 of 3000 people who inject drugs, registered at the Civil Hospital in Karachi, Pakistan.

Results: The mean age was 30 years, 181 were married, 179 were illiterate and 287 had income < 5000 rupees per month. Only 63 patients were adherent to ART and 343 were alcoholics. Nonadherence was greater in patients who were single and did not have children. The most common reason for missing ART was that they simply forgot to take the tablets.

Conclusion: We conclude that adherence to ART among intravenous drug users was low. Family cohesion and support were essential to maintain adherence to ART

Substance use among adolescents in sub-Saharan Africa: a systematic review and meta-analysis

Background. In sub-Saharan Africa, substance use among adolescents has continued to be a major public health concern, albeit poorly documented across many settings. Objective. To estimate the prevalence of substance use among adolescents in sub-Saharan Africa. Methods. We searched Pubmed, EMBASE, AJOL and Google Scholar for population-based studies on adolescents (age 10 - 19 years) and reporting on the prevalence of substance use across sub-Saharan Africa. Search dates were from January 2000 to December 2016. A random effects meta-analysis was conducted with pooled prevalence rates (and 95% confidence interval (95% CI)) of estimated substance abuse among adolescents in sub-Saharan Africa. Results. Twenty-seven studies across sub-Saharan Africa including 143 201 adolescents (mean age 15.6 years) were selected. The overall prevalence of 'any substance use' in sub-Saharan Africa was 41.6%, with the highest rate in Central Africa at 55.5%. The use of caffeine-containing products (including coffee or kola nut) was most predominant at 41.2% (95% CI 24.3 - 58.1) but limited to West Africa. These were followed by alcohol at 32.8% (95% CI 26.0 - 39.5), tobacco products 23.5% (95% CI 17.7 - 29.3), khat 22.0% (95% CI 12.5 - 31.5) and cannabis 15.9% (95% CI 12.2 - 19.1). Other abused substances included depressants at 11.3% (95% CI 6.5 - 16.1), amphetamines 9.4% (95% CI 6.0 - 12.9), heroin 4.0% (95% CI 3.5 - 4.5) and cocaine 3.9% (95% CI 1.4 - 6.5). Conclusion. Our study reflects a high use of psychoactive substances and drugs among adolescents in sub-Saharan Africa. It is important that interventions and rehabilitation programmes are comprehensive and targeted at adolescents and parents in these settings

Correlates of perceived risk of HIV infection among persons who inject drugs in Tijuana, Baja California, Mexico / Correlaciones de percepción de riesgo de infección con VIH entre personas que se inyectan droga en Tijuana, Baja California, México

Objective. We identified correlates of perceived risk of HIV infection among persons who inject drugs (PWID) in Tijuana. Materials and methods. PWID ≥18 years of age who injected drugs in the past month were recruited between 2006-2007 and completed risk assessment interviews and serologic testing for HIV, syphilis, and tuberculosis. Logistic regression was used to determine factors associated with high-perceived risk of HIV infection. Results. Among 974 PWID, HIV prevalence was 4.4%; 45.0% of participants perceived themselves to be more likely to become HIV infected relative to other PWID in Tijuana. Participants who reported high-perceived risk of HIV infection participated in high-risk behaviors such as injecting with used syringes, transactional sex, and were less likely to have had an HIV test. Conclusions. Recognition of HIV infection risk was associated with high risk behaviors and markers of vulnerability. Findings support efforts to encourage HIV testing and access to health care for this vulnerable population.

Los resultados apoyan los esfuerzos para fomentar las pruebas para VIH y acceso a servicios de salud para esta población vulnerable.

Burden of blood transmitted infections in substance users admitted for inpatient treatment in Singapore and the associated factors

<p><b>INTRODUCTION</b>There is paucity of local data on the prevalence of blood transmitted infections (BTIs), such as hepatitis B, hepatitis C and human immunodeficiency virus (HIV) infections, among illicit drug users. This study aimed to examine the prevalence of BTIs among substance dependent inpatients and identify the factors associated with BTIs.</p><p><b>METHODS</b>We conducted a retrospective analysis of clinical notes of 170 inpatients with a diagnosis of substance dependence who were admitted at the National Addictions Management Service, Singapore, between 1 June 2009 and 31 May 2010.</p><p><b>RESULTS</b>Majority of the 170 inpatients were male (88.2%) and Chinese (58.2%). The mean age of the patients was 43.1 years, and the main drug of abuse was opioids (86.5%). BTIs were found in 70 (41.2%) inpatients; the prevalence of hepatitis B, hepatitis C and HIV infections was 3.7%, 39.6% and 0%, respectively. Lifetime intravenous drug use, but not needle-sharing, was more common among inpatients who were positive for BTIs (p < 0.01). Logistic regression analysis showed that lifetime intravenous drug use (OR 4.3, 95% CI 1.7- 10.8, p < 0.01) was the only significant predictor of BTIs.</p><p><b>CONCLUSION</b>A large proportion (41.2%) of the substance users seeking help was positive for at least one BTI. Lifetime intravenous drug users were found to be more than four times more likely to have a BTI. Early detection and prevention is essential to improve prognosis.</p>

Study on spousal notification in HIV discordant couples and associated factors in four provinces of China / 中华流行病学杂志

<p><b>OBJECTIVE</b>This study was aimed to investigate the ways of spousal notification and its associated factors among HIV discordant couples.</p><p><b>METHODS</b>A face-to-face questionnaire survey was conducted in Henan, Yunnan, Sichuan provinces and Guangxi Zhuang Autonomous Region in China. Information including democratic characteristics, knowledge and behaviors correlated with HIV infections and ways of HIV infectious status notification was collected. 'Data information system' on AIDS prevention and control was used to collect information on the transmission route.</p><p><b>RESULTS</b>A total of 770 pairs of HIV discordant couples were studied, among which 414 (53.77%) HIV positive respondents reported as self-notification, with another 44.68% were notified by medical staff. Factors associated with ways of notification included gender, nation, transmission route, and education level. HIV positive respondents who were female, under Han nationality, being paid blood donors, having had higher education level, were more likely to inform their HIV negative spouse by themselves.</p><p><b>CONCLUSION</b>Nationality and HIV transmission route of the HIV positive individuals were found as significant factors associated with ways of spousal notification. Therefore, HIV discordant couples notification should be strengthened, especially in the Minority-living areas and areas where HIV transmission was predomint through sexual contact and/or via injected drug use.</p>

A study on the risk and its determinants of HIV transmission by syringe sharing among HIV-positive drug users / 中华预防医学杂志

<p><b>OBJECTIVE</b>To understand the risks and associated factors of HIV transmission by sharing syringes among HIV-positive drug users.</p><p><b>METHOD</b>The survey was conducted among HIV-positive injecting drug users (IDUs-HIV+) who received HIV counseling, testing and treatment in Changsha city Infectious Disease Hospital and Hengyang city No.3 People's Hospital from July 2012 to May 2013 to understand their socio-demographic characteristics, HIV prevalence and syringe sharing. A total of 503 IDUs-HIV+ were involved in and provided the contact list of 2 460 drug users who had the syringe sharing experience over one month with IDUs-HIV+. 420 IDUs-HIV+ among 503 were defined as infection sources due to sharing syringe with at least one drug user. Among them, 234 HIV-negative persons were in control group, and 186 HIV-positive were in cased group. A total of 1 220 drug users were followed up among 2 460 and defined as vulnerable population. The HIV transmission rate was calculated based on the HIV prevalence among vulnerable population. Based on the result of HIV transmission to vulnerable population from 420 infection sources, case-control study and the multivariate logistic regression analysis were adopted to explore the associated factors of HIV transmission among IDUs-HIV+.</p><p><b>RESULTS</b>As the sources of HIV transmission, 420 IDUs-HIV+ had an average duration of (4.5 ± 1.2) years for drug use. As a susceptible population, 1 220 drug users sharing syringes with the 420 IDUs-HIV+ had an average duration of (1.1 ± 0.5) years for drug use. There were 238 HIV-positive persons among 1 220 vulnerable drug users, with a transmission rate of 0.57. In the case-control study, the proportion of male subjects was 87.1% (162/186) in the case group, which was higher than that in the control group (77.8%, 182/234). The proportion of subjects who received support after knowing their HIV infection status was 51.1% (95/186) in the case group, which was lower than that in the control group (79.5%, 186/234). The proportion of subjects sharing syringes every time of using drugs was 47.8% (89/186) in the case group, which was higher than that in the control group (36.8%, 86/234). The proportion of subjects having AIDS awareness was 21.0% (39/186) in the case group, which was lower than that in the control group (64.5%, 151/234); the proportion of subjects having close contact with HIV-positive persons for more than 106 days was 60.2% (112/186) in the case group, which was higher than that in the control group (31.6%, 74/234). The proportion of subjects maintaining the original drug use method after being infected with HIV was 50.5% (94/186) in the case group, which was higher than that in the control group (16.7%, 39/234) (all P values < 0.05). The multivariate logistic regression analysis was carried out to analyse high correlate factors of HIV transmission by sources of transmission, and the AIDS awareness, duration of contact between sources of transmission and vulnerable population, access to support following confirmed HIV infection were protective factors, OR (95% CI) values were 0.155 (0.104-0.262), 0.170 (0.106-0.253), and 0.306 (0.189-0.450), respectively; while the frequency of syringe sharing and continuous drug use after being infected with HIV were risk factors, and the OR (95% CI) values were 3.06 (1.77-5.29), and 3.54 (2.16-5.80), respectively.</p><p><b>CONCLUSION</b>HIV transmission by IDUs-HIV+ might be contained by raising AIDS awareness, providing comprehensive psychological support, conducting needle exchange and methadone maintenance treatment and reducing syringe sharing.</p>

The anti HCV was highest in those infected with HIV through injection drug use (77.27%), the anti-HCV positive rates in those infected with HIV through blood donation/transfusion, heterosexual contact, homosexual contact and mother-to-child transmission were 15.06%, 15.81%, 3.74% and 8.96%, respectively. Kaifeng (32.04%), Nanyang (14.67%), Shangqiu (25.00%), Zhumadian (25.00%) and Zhoukou (18.86%) were the first five prefectures with the high anti-HCV positive rates. The anti-HCV positive rate in BED positive patients (recent HIV-1 infections) was 7.50% (86/1 146). The multivariate logistic regressions analysis revealed that BED negative, aged >40 years, being farmer, HIV infection though injection drug use and living in in Kaifeng, Nanyang, Shangqiu, Zhumadian and Zhoukou were the risk factors for HCV infection.</p><p><b>CONCLUSION</b>The positive rate of anti-HCV declined between 2012-2014 in newly reported HIV infection cases in Henan, but the positive rate of anti-HCV was high in risk population and in some areas.</p>

A case of peritoneal dialysis-associated peritonitis by Rothia mucilaginosa

Rothia muciliaginosa (R. mucilaginosa) is a facultative, Gram-positive coccus that is considered to be part of the normal flora of the mouth and respiratory tract. There are sporadic reports of the organism causing endocarditis in patients with heart valve abnormalities, as well as meningitis, septicemia, and pneumonia associated with intravenous drug abuse. However, it is an unusual pathogen in cases of peritoneal dialysis (PD)-associated peritonitis. Although R. mucilaginosa is generally susceptible to penicillin, ampicillin, cefotaxime, imipenem, rifampicin, and glycopeptides, there are no guidelines for the treatment of PD-associated peritonitis. Herein, we report a case of PD-associated peritonitis due to R. mucilaginosa that was resolved with intraperitoneal antibiotic treatment.
