RESUMO

OBJECTIVE: Early readmission rates are becoming an integral measure of the quality of care for hospitalized patients with chronic diseases. The incidence and predictors of early readmission in patients with inflammatory bowel disease (IBD) are uncertain. Risk factors for readmission over the first few weeks may differ from those that influence re-hospitalization at later time points. We examined the incidence and predictors of both 30-day and 90-day readmissions among ulcerative colitis (UC) patients. MATERIALS AND METHODS: A retrospective, cohort study was performed including all severe UC patients admitted to a tertiary-care hospital between January 2007 and December 2011. All-cause readmissions to the medical or surgical service within 30 and 90 days were recorded to allow the calculation of early readmission rates. We used multiple logistic regression to analyze demographic, hospital-related, general medical and IBD-specific factors as potential risk factors for readmission. RESULTS: There were a total of 229 patients discharged following hospitalization for severe UC. The 30- and 90-day readmission rates were 11.7% and 20.5%, respectively. Forty-seven percent of early readmissions were for colectomy. In the 30-day analysis, only the presence of extensive colitis (odds ratio 3.59; 95% confidence interval [CI] 1.41-9.13) compared with left-sided disease was independently associated with readmission. Extensive colitis (3.09, 95% CI 1.33-7.08), albumin on admission (0.56, 0.31-0.99) and being admitted to a housestaff service (2.87, 95% CI 1.14-6.54), were independent predictors of readmission at 90 days. CONCLUSIONS: Early readmission is common in IBD. Independent risk factors for early readmission included extensive colitis, admission albumin, and being admitted to a housestaff service.

RESUMO

To map the context of HIV in closed settings in Papua New Guinea (PNG), semi-structured interviews were undertaken with 56 prisoners and detainees and 60 key stakeholders. The nature of HIV-related risk differs for detained women and men, and reflects important gender-based issues present in PNG society more broadly. Women in detention are vulnerable to sexual violence and exploitation and at greatest risk of HIV while detained in police holding cells, where they are typically supervised by male officers, in contrast to prisons, where they have little contact with male staff. HIV risk for men in prison is associated with consensual and non-consensual sex; this risk is perpetuated by a pervasive culture of denial and institutionalised homophobia. The illegal nature of sodomy and male-to-male sex provides Correctional Services the legal grounds by which to refuse access to condoms for prisoners. Addressing HIV risk among detained men and women in PNG requires the reform of legislation, police and prison practices and an understanding of broader structural problems of gender-based violence and stigma and discrimination.

RESUMO

BACKGROUND: Injection Drug use is associated with increased HIV risk behaviour that may result in the transmission of HIV and poor access to HIV prevention and treatment. In 2020, Uganda introduced the 'medication for opioid use disorder (MOUD) treatment' for People who inject drugs (PWID). We analysed the 12-month retention and associated factors among PWID enrolled on MOUD treatment in Kampala, Uganda. METHODS: We conducted a retrospective analysis of 343 PWID with OUD who completed 14 days of methadone induction from September 2020 to July 2022. Retention was defined as the number of individuals still in the programme divided by the total number enrolled, computed at 3-, 6-, 9-, and 12 months using lifetable and Kaplan-Meier survival analyses. Cox proportional regression analyses were conducted to assess factors associated with retention in the programme in the first 12 months. RESULTS: Overall, 243 (71%) of 343 participants stabilized at a methadone dose of 60 mg or more. The majority of participants were males (n = 284, 82.8%), and the median (interquartile range, IQR) age was 31 (26-38) years. Most participants (n = 276, 80.5%) lived 5 km or more away from the MOUD clinic. Thirty (8.8%) were HIV-positive, 52 (15.7%) had a major mental illness and 96 (27.9%) had a history of taking alcohol three months before enrollment. The cumulative retention significantly declined from 83.4% (95%CI = 79.0-87.0) at 3months to 71.9% (95%CI = 67.2-76.6) at 6months, 64% 95%CI = 58.7-68.9) at 9months, and 55.2%; 95% CI (49.8-60.3% at 12months. The 12-month retention was significantly higher for participants on methadone doses of 60 mg or more (adj.HR = 2.1, 95%CI = 1.41-3.22), while participants resident within 5 km of the MOUD clinic were 4.9 times more likely to be retained at 12 months, compared to those residing 5 km or more, (adj. HR = 4.81, 95%CI = 1.54-15). Other factors, including predisposing, need, and enabling factors, were not associated with retention. CONCLUSION: Our study demonstrates acceptable 12-month retention rates for people who inject drugs, comparable to previous studies done in both developing and developed countries. Sustaining and improving retention may require enhanced scaling up of MOUD dose to an optimal level in the first 14 days and reducing the distance between participant locale and MOUD clinics.

RESUMO

BACKGROUND: During 2021 and 2023 two simplified Biological and Behavioural Study (BBS-Lite) surveys, and in 2022 one Standard Integrated Biological and Behavioural Study (IBBS), were conducted among people who inject drugs in seven cities in Georgia. From these, an opportunity to compare the implementation of these survey methods and results was able to be gained. METHODS: The two survey types were compared to find points of similarity and difference in their methodologies. The methodologies of the IBBS and BBS-Lite studies shared many characteristics, including the cities where they were implemented, recruitment criteria, sample sizes, and common questionnaire items. All studies were multi-centre cross-sectional involving administration of a face-to-face behavioural questionnaire and collection of biological specimens for testing of HIV, syphilis, hepatitis B virus (HBV), and hepatitis C virus (HCV). The main differences were in the sampling methods. The IBBS utilised respondent-driven sampling (RDS) while participants of the BBS-Lite studies were enrolled through consecutive recruitment at the harm reduction (HR) programme sites and on outreach and through snowball sampling. We compared the results from each study as well as the implementation modalities such as time taken and budgetary requirements, and the complexity of implementation. RESULTS: Considerably less time was required for recruitment, as well as for interviewing, data entry (4 times less) and the analysis for the BSS-Lite studies compared to the IBBS. The BSS-Lite study budgets were at least 2.5 times less than of the IBBS study. The recruited samples were comparable for age distribution, median age at first injection, the last drug injected, sharing of drug injecting equipment or receiving opioid agonist maintenance treatment (OAMT) during the last 12 months. HIV and HCV prevalence were similar including for stratifications by age, client status and city of recruitment. CONCLUSION: Our findings have demonstrated that if implemented on a regular basis, the BBS-Lite can be a complementary solution for systematic data collection, filling surveillance gaps and addressing the challenges that persist in obtaining important data on people who inject drugs (PWID) between IBBS rounds in the country. The methodology is recommended for testing in other settings and in other key populations. In addition, the data collected on a routine base can help the harm reduction (HR) program to better understand the changes in the drug scene and observe new trends in HIV risks and drug injecting behaviours, possible barriers for access to harm reduction, drug treatment, and HIV and/or viral hepatitis testing and treatment services.

RESUMO

Background: Uganda has implemented targeted interventions to address the rising burden of injection drug use, yet barriers persist in reaching persons who inject drugs (PWID). This study describes the characteristics of people who inject drugs, physical and mental health states, and associated risk behaviors, to inform the designing of programs that are tailored to client's needs and preferences. Methods: A cross-sectional survey was conducted between August and December 2023 at selected hotspots in Kampala, interviewing 499 PWID aged ≥18 years. Data was collected using a semi-structured questionnaire administered by peer educators and Uganda Harm Reduction Network (UHRN) counselors. Measurements included socio-demographics, injecting drug use and sexual risk behaviors, and medical history. HIV serostatus was dtermined by self-report and testing for participants who had no recent history of testing and consented to be tested. Binary logistic regression was used to establish the relationship between HIV infection and risky drug- and sexual behaviors of PWID. Results: Participants were predominantly Ugandan (95.2%), male (73.2%), unmarried (55.9%), unemployed (81.8%), with higher levels of education and varying ages. Mental disorders were prevalent, with 48.7% reporting at least one underlying condition, including depression (30.8%) and anxiety (9.6%). Physical health issues were also noted, with reported cases of fever (32.9%), cough (32.5%), malaria (22%) and sexually transmitted infections (STIs) (15%).Regarding drug use patterns, the majority (82.6%) were introduced to drugs by close acquaintances, with 70.9% categorized as people who inject drugs. HIV prevalence among injecting drug users was 3.7%, with higher rates among females (8.4%) and non-Ugandans (16.7%). Being female and experiencing difficulty accessing sterile injection materials were associated with HIV-positive status, highlighting the complex interplay between socio-demographic factors, risk behaviors, and HIV infection among individuals with injecting drug use Disorder in Uganda. Conclusion: Our study provides a comprehensive insight into the socio-demographic, mental, physical health, and HIV risk behavoir of PWID in Kampala, Uganda. The findings indicate significant vulnerabilities to injecting drug use, mental disorders, and high-risk behaviors that predispose this population to HIV infection. Despite a low HIV prevalence compared to previous estimates, the interplay between drug use, risky injecting practices, and sexual behaviors suggests an urgent need for targeted interventions to address these intertwined challenges.

RESUMO

OBJECTIVE: To systematically review cohort studies of mortality among people who inject drugs, examine mortality rates and causes of death in this group, and identify participant- and study-level variables associated with a higher risk of death. METHODS: Tailored search strings were used to search EMBASE, Medline and PsycINFO. The grey literature was identified through online grey literature databases. Experts were consulted to obtain additional studies and data. Random effects meta-analyses were performed to estimate pooled crude mortality rates (CMRs) and standardized mortality ratios (SMRs). FINDINGS: Sixty-seven cohorts of people who inject drugs were identified, 14 of them from low- and middle-income countries. The pooled CMR was 2.35 deaths per 100 person-years (95% confidence interval, CI: 2.12-2.58). SMRs were reported for 32 cohorts; the pooled SMR was 14.68 (95% CI: 13.01-16.35). Comparison of CMRs and the calculation of CMR ratios revealed mortality to be higher in low- and middle-income country cohorts, males and people who injected drugs that were positive for human immunodeficiency virus (HIV). It was also higher during off-treatment periods. Drug overdose and acquired immunodeficiency syndrome (AIDS) were the primary causes of death across cohorts. CONCLUSION: Compared with the general population, people who inject drugs have an elevated risk of death, although mortality rates vary across different settings. Any comprehensive approach to improving health outcomes in this group must include efforts to reduce HIV infection as well as other causes of death, particularly drug overdose.

RESUMO

BACKGROUND: Injecting drug use is an important risk factor for transmission of viral hepatitis, but detailed, transparent estimates of the scale of the issue do not exist. We estimated national, regional, and global prevalence and population size for hepatitis C virus (HCV) and hepatitis B virus (HBV) in injecting drug users (IDUs). METHODS: We systematically searched for data for HBV and HCV in IDUs in peer-reviewed databases (Medline, Embase, and PsycINFO), grey literature, conference abstracts, and online resources, and made a widely distributed call for additional data. From 4386 peer-reviewed and 1019 grey literature sources, we reviewed 1125 sources in full. We extracted studies into a customised database and graded them according to their methods. We included serological reports of HCV antibodies (anti-HCV), HBV antibodies (anti-HBc), or HBV surface antigen (HBsAg) in studies of IDUs with more than 40 participants (<100% HIV-positive) and sampling frames that did not exclude participants on the basis of age or sex. With endorsed decision rules, we calculated prevalence estimates with anti-HCV and anti-HBc as proxies for exposure and HBsAg as proxy for current infection. We combined these estimates with IDU population sizes to calculate the number of IDUs with positive HBV or HCV statuses. FINDINGS: We located eligible reports with data for prevalence of anti-HCV in IDUs for 77 countries; midpoint prevalence estimates suggested 60-80% of IDUs had anti-HCV in 25 countries and more than 80% of IDUs did so in 12 countries. About 10.0 million (range 6.0-15.2) IDUs worldwide might be anti-HCV positive. China (1.6 million), USA (1.5 million), and Russia (1.3 million) had the largest such populations. We identified eligible HBsAg reports for 59 countries, with midpoint prevalence estimates of 5-10% in 21 countries and more than 10% in ten countries. Worldwide, we estimate 6.4 million IDUs are anti-HBc positive (2.3-9.7 million), and 1.2 million (0.3-2.7 million) are HBsAg positive. INTERPRETATION: More IDUs have anti-HCV than HIV infection, and viral hepatitis poses a key challenge to public health. Variation in the coverage and quality of existing research creates uncertainty around estimates. Improved and more complete data and reporting are needed to estimate the scale of the issue, which will inform efforts to prevent and treat HCV and HBV in IDUs.

RESUMO

HIV can spread rapidly between people who inject drugs (through injections and sexual transmission), and potentially the virus can pass to the wider community (by sexual transmission). Here, we summarise evidence on the effectiveness of individual-level approaches to prevention of HIV infection; review global and regional coverage of opioid substitution treatment, needle and syringe programmes, and antiretroviral treatment; model the effect of increased coverage and a combination of these three approaches on HIV transmission and prevalence in injecting drug users; and discuss evidence for structural-level interventions. Each intervention alone will achieve modest reductions in HIV transmission, and prevention of HIV transmission necessitates high-coverage and combined approaches. Social and structural changes are potentially beneficial components in a combined-intervention strategy, especially when scale-up is difficult or reductions in HIV transmission and injection risk are difficult to achieve. Although further evidence is needed on how to optimise combinations of interventions in different settings and epidemics, we know enough now about which actions are effective: the challenge is to deliver these well and to scale.

RESUMO

BACKGROUND: Previous reviews have examined the existence of HIV prevention, treatment, and care services for injecting drug users (IDUs) worldwide, but they did not quantify the scale of coverage. We undertook a systematic review to estimate national, regional, and global coverage of HIV services in IDUs. METHODS: We did a systematic search of peer-reviewed (Medline, BioMed Central), internet, and grey-literature databases for data published in 2004 or later. A multistage process of data requests and verification was undertaken, involving UN agencies and national experts. National data were obtained for the extent of provision of the following core interventions for IDUs: needle and syringe programmes (NSPs), opioid substitution therapy (OST) and other drug treatment, HIV testing and counselling, antiretroviral therapy (ART), and condom programmes. We calculated national, regional, and global coverage of NSPs, OST, and ART on the basis of available estimates of IDU population sizes. FINDINGS: By 2009, NSPs had been implemented in 82 countries and OST in 70 countries; both interventions were available in 66 countries. Regional and national coverage varied substantially. Australasia (202 needle-syringes per IDU per year) had by far the greatest rate of needle-syringe distribution; Latin America and the Caribbean (0.3 needle-syringes per IDU per year), Middle East and north Africa (0.5 needle-syringes per IDU per year), and sub-Saharan Africa (0.1 needle-syringes per IDU per year) had the lowest rates. OST coverage varied from less than or equal to one recipient per 100 IDUs in central Asia, Latin America, and sub-Saharan Africa, to very high levels in western Europe (61 recipients per 100 IDUs). The number of IDUs receiving ART varied from less than one per 100 HIV-positive IDUs (Chile, Kenya, Pakistan, Russia, and Uzbekistan) to more than 100 per 100 HIV-positive IDUs in six European countries. Worldwide, an estimated two needle-syringes (range 1-4) were distributed per IDU per month, there were eight recipients (6-12) of OST per 100 IDUs, and four IDUs (range 2-18) received ART per 100 HIV-positive IDUs. INTERPRETATION: Worldwide coverage of HIV prevention, treatment, and care services in IDU populations is very low. There is an urgent need to improve coverage of these services in this at-risk population.

RESUMO

There is limited information on contraceptive values and preferences of sex workers. We conducted a mixed-method study to explore contraceptive values and preferences among sex workers. We conducted an online survey with individuals from 38 countries (n = 239), 6 focus group discussions (FGD, n = 68) in Zimbabwe, and 12 in-depth phone interviews (IDI) across 4 world regions, in June and July of 2019. Participants were asked about awareness of contraceptives, methods they had used in the past, and the determinants of their choices. Differences between respondents from high-, low- and middle- income countries were examined. Qualitative data were analysed thematically. Survey participants reported an awareness of modern contraceptive methods. FGDs found that younger women had lower awareness. Reports of condomless sex were common and modern contraceptive use was inconsistent. Determinants of contraceptive choices differed by setting according to results of the survey, FGD, and IDI. Regardless of country income level, determinants of contraceptive choices included ease of use, ease of access to a contraceptive method, and fewer side effects. Healthcare provider attitudes, availability of methods, and clinic schedules were important considerations. Most sex workers are aware of contraceptives, but barriers include male partners/clients, side effects, and health system factors such as access and clinic attitudes towards sex workers.

RESUMO

BACKGROUND: WHO has set targets for hepatitis C virus (HCV) elimination by 2030. We did a global systematic review of HCV prevalence and incidence in men who have sex with men (MSM) to provide updated estimates that can guide community education and public health policy. METHODS: We did a systematic review and meta-analysis of studies published and listed on MEDLINE or Embase between Jan 1, 2000, and Oct 31, 2019, including conference proceedings. Studies were eligible if they reported measures of HCV prevalence or HCV incidence (or both) among MSM. Studies that relied on participants' self-reported HCV status with no laboratory confirmation were excluded. Pooled HCV estimates in MSM were stratified by HIV status and by injecting drug use, then by WHO region and by income level. Random-effects meta-analysis was done to account for between-study heterogeneity and examined using the I2 statistic. Pooled HCV prevalence was also compared with HCV estimates in the general population and presented as prevalence ratios (PRs). In HIV-negative MSM, incidence estimates were stratified by use of HIV pre-exposure prophylaxis (PrEP). The systematic review was registered with PROSPERO, number CRD42020156262. FINDINGS: Of 1221 publications identified, 194 were deemed to be eligible and included in the systematic review and meta-analysis. Overall, the pooled HCV prevalence in MSM was 3·4% (95% CI 2·8-4·0; I2=98·0%) and was highest in Africa (5·8%, 2·5-10·4) and South-East Asia (5·0%, 0·0-16·6). Globally, HCV prevalence was 1·5% (1·0-2·1) in HIV-negative MSM and 6·3% (5·3-7·5) in HIV-positive MSM. Compared with the general population, HCV prevalence was slightly higher in HIV-negative MSM (PR 1·58, 95% CI 1·14-2·01) and markedly higher (6·22, 5·14-7·29) in HIV-positive MSM. Pooled HCV prevalence was substantially higher in MSM who had ever injected drugs (30·2%, 22·0-39·0) or currently injected drugs (45·6%, 21·6-70·7) than in those who never injected drugs (2·7%, 2·0-3·6). In HIV-negative MSM, the pooled HCV incidence was 0·12 per 1000 person-years (95% CI 0·00-0·72) in individuals not on PrEP and 14·80 per 1000 person-years (9·65-20·95) in individuals on PrEP. HCV incidence in HIV-positive MSM was 8·46 per 1000 person-years (6·78-10·32). INTERPRETATION: HIV-positive MSM are at substantially increased risk of HCV. Overall, HIV-negative MSM had a slightly higher prevalence of HCV than the general population but had a lower prevalence than HIV-positive MSM. High HCV incidence in more recent PrEP studies suggests that as PrEP use increases, greater HCV transmission might occur. HCV burden in MSM varies considerably by region, which is likely to be associated with variation in the prevalence of injecting drug use and HIV. FUNDING: World Health Organization.

RESUMO

INTRODUCTION: WHO's 2019 report on HIV drug resistance (HIVDR) documents a high prevalence of pretreatment drug resistance (PDR) among populations initiating first-line antiretroviral therapy (ART) in low- and middle-income countries (LMIC). However, systematic evidence on the prevalence of PDR among key populations remains limited. We performed a systematic review to characterize levels of PDR in key population groups and compared them to levels of PDR in the "general population" across different geographical regions. METHODS: Ten electronic databases were searched for papers published until February 2019 that included predefined search terms. We included studies that reported the number of successfully tested genotypes and the number of genotypes with drug resistance mutations among antiretroviral therapy treatment naïve people, recently infected people, or people initiating first-line ART from key populations. To assess the prevalence of PDR for each key population, we pooled estimates using random-effects meta-analysis of proportions. Where possible, we computed the differences in the odds of PDR (any, and by drug class) present in each key population compared to the "general population". The I2 statistic (a measure of heterogeneity between studies) is reported. RESULTS AND DISCUSSION: A total of 332 datasets (from 218 studies) and 63,111 people with successful HIVDR genotyping were included in the analysis. The pooled prevalence estimate of any PDR was high among men who have sex with men (13.0%, 95% CI 11.0 to 14.0%, I2  = 93.19), sex workers (17.0%, 95% CI 6.0 - 32.0, I2  = 87.31%) and people in prisons (18.0%, 95% CI 11.0 to 25.0, I2  = 70.18%), but less so among people who inject drugs (7.0%, 95% CI 5.0 to 10.0, I2  = 90.23). Overall, men who have sex with men were more likely to carry any PDR compared to the "general population," a finding which was statistically significant (odds ratio (OR) 1.28, 95% CI 1.13 - 1.46, I2 48.9%). CONCLUSIONS: High prevalence of PDR found in key populations highlights the need to increase access to effective first-line HIV treatment. The low prevalence of nucleotide reverse transcriptase inhibitor (NRTI) PDR suggests that current WHO recommendations for pre-exposure prophylaxis (PrEP) regimens will remain effective and can be scaled up to prevent new HIV infections in high-risk groups.

RESUMO

BACKGROUND: Injecting drug use is an increasingly important cause of HIV transmission in most countries worldwide. Our aim was to determine the prevalence of injecting drug use among individuals aged 15-64 years, and of HIV among people who inject drugs. METHODS: We did a systematic search of peer-reviewed (Medline, EmBase, and PubMed/BioMed Central), internet, and grey literature databases; and data requests were made to UN agencies and international experts. 11 022 documents were reviewed, graded, and catalogued by the Reference Group to the UN on HIV and Injecting Drug Use. FINDINGS: Injecting drug use was identified in 148 countries; data for the extent of injecting drug use was absent for many countries in Africa, the Middle East, and Latin America. The presence of HIV infection among injectors had been reported in 120 of these countries. Prevalence estimates of injecting drug use could be ascertained for 61 countries, containing 77% of the world's total population aged 15-64 years. Extrapolated estimates suggest that 15.9 million (range 11.0-21.2 million) people might inject drugs worldwide; the largest numbers of injectors were found in China, the USA, and Russia, where mid-estimates of HIV prevalence among injectors were 12%, 16%, and 37%, respectively. HIV prevalence among injecting drug users was 20-40% in five countries and over 40% in nine. We estimate that, worldwide, about 3.0 million (range 0.8-6.6 million) people who inject drugs might be HIV positive. INTERPRETATION: The number of countries in which the injection of drugs has been reported has increased over the last decade. The high prevalence of HIV among many populations of injecting drug users represents a substantial global health challenge. However, existing data are far from adequate, in both quality and quantity, particularly in view of the increasing importance of injecting drug use as a mode of HIV transmission in many regions.

RESUMO

We examined the proportion and correlates of loss to follow-up (LTFU) among female entertainment and sex workers (FESWs) in a longitudinal HIV prevention intervention trial in Cambodia. The Cambodia Integrated HIV and Drug Prevention Intervention trial tested a comprehensive package of interventions aimed at reducing amphetamine-type stimulant use and HIV risk among FESWs in ten provinces. The present study estimated the proportion of women LTFU and assessed factors associated with LTFU. Logistic regression analyses were used. Of a total 596 women enrolled, the cumulative proportion of LTFU was 29.5% (n = 176) between zero- and 12-month follow-up. In multivariate analyses, women with no living children (adjusted odds ratio [AOR] 1.6; 95% confidence interval [CI]: 1.1, 2.3) and those who experienced recent food insecurity (AOR 1.7; 95%CI: 1.1, 2.7) were more likely to be LTFU. Women who were members of the SMARTgirl HIV prevention programme for ≥ 6 months compared to non-members were less likely to be LTFU (AOR 0.3; 95%CI: 0.2, 0.6). LTFU was moderately high in this study and similar to other studies, indicating a need for strategies to retain this population in HIV prevention programmes and research. Interventions aimed at stabilizing women's lives, including reducing food insecurity and creating communities of engagement for FESWs, should be considered.

RESUMO

BACKGROUND: Non-viral injecting-related injuries and diseases (IRID), such as abscesses and vascular damage, can result in significant morbidity and mortality if untreated. There has been no systematic assessment of the prevalence of non-viral IRID among people who inject drugs; this review aimed to address this gap, as well as identify risk factors for experience of specific IRID. METHODS: We searched MEDLINE, Embase and CINAHL databases to identify studies on the prevalence of, or risk factors for, IRID directly linked to injecting in samples of people who inject illicit drugs. RESULTS: We included 33 studies: 29 reported IRID prevalence in people who inject drugs, and 17 provided data on IRID risk factors. Skin and soft tissue infections at injecting sites were the most commonly reported IRID, with wide variation in lifetime prevalence (6-69%). Female sex, more frequent injecting, and intramuscular and subcutaneous injecting appear to be associated with skin and soft tissue infections at injecting sites. Cleaning injecting sites was protective against skin infections. Other IRID included infective endocarditis (lifetime prevalence ranging from 0.5-12%); sepsis (2-10%); bone and joint infections (0.5-2%); and thrombosis and emboli (3-27%). CONCLUSIONS: There were significant gaps in the data, including a dearth of research on prevalence of IRID in low- and middle-income countries, and potential risk and protective factors for IRID. A consistent approach to measurement, including standardised definitions of IRID, is required for future research.

RESUMO

BACKGROUND: Utilization of pharmacologic venous thromboembolism (VTE) prophylaxis in inflammatory bowel disease (IBD) patients seems to be suboptimal with reported rates as low as 50% in some studies. Implementation of an electronic alert system seems to be an effective tool for increasing VTE prophylaxis rates in medical inpatients. To date, no studies have assessed whether this approach is associated with improved rates of pharmacologic VTE prophylaxis specifically in IBD patients. AIMS: To determine the efficacy of an electronic alert in improving VTE prophylaxis rates in hospitalized IBD patients. METHODS: We conducted a retrospective cohort study of 576 hospitalized IBD patients. The medical record of each patient was then examined to determine whether pharmacologic VTE prophylaxis was both ordered and administered, the timing of pharmacologic VTE prophylaxis, and reasons for any missed doses. RESULTS: The VTE pharmacologic prophylaxis rate was improved from 60% to 81.2% following the implementation of the electronic alert system (p < .001). An increase in prophylaxis rates was seen in both medical (26.3% vs. 62.8%, p < .001) and surgical services (83.7% vs. 95.5%, p < .001). In patients who received pharmacologic VTE prophylaxis, 16% of all ordered doses were not administered and 57.3% of missed doses were the result of patient refusal. Hospitalization after implementation of the electronic alert system (odds ratio [OR] 4.71, 95% confidence interval [CI] 2.94-7.57) and admission to a surgical service (OR 14.3, 95% CI 8.62-24.39) were predictive of VTE pharmacologic prophylaxis orders. CONCLUSIONS: The introduction of an electronic alert system was associated with a significant increase in rates of pharmacologic VTE prophylaxis. However, orders were often delayed and doses not always administered. The most common reason that ordered doses were not given was patient refusal.

RESUMO

Indonesia has the third highest number of people living with HIV/AIDS (PLWH) and the greatest increase in proportion of AIDS-related mortality in the Asia Pacific region between 2005 and 2013. Longitudinal mortality data among PLWH in Indonesia are limited. We conducted a retrospective cohort study from medical records of antiretroviral treatment (ART) recipients attending Badung General Hospital (BGH) and Bali Medica Clinic (BMC) between 2006 and 2014. We explored incidence of mortality by Kaplan-Meier analysis and identified predictors using a Cox proportional hazard model. In total, 575 patients were included in the analysis; the majority were male. The overall mortality rate was 10% per year. Multivariate analysis suggested that being male (adjusted hazard ratio [aHR]: 2.74; 95% confidence interval [CI]: 1.34-5.59), having a lower education (aHR: 2.17; 95%CI: 1.31-3.61), having heterosexual (aHR: 7.40; 95% CI: 2.61-21.00) or injecting drug use (aHR: 13.20; 95% CI: 3.17-55.00) as the likely transmission risk category, starting treatment with low CD4 cell counts (aHR: 3.18; 95% CI: 1.16-8.69), and not having a treatment supervisor (aHR: 4.02; 95% CI: 2.44-6.65) were independent predictors of mortality. The mortality was high, particularly in the first three months after initiating ART. These findings highlight the need to encourage HIV testing and early diagnosis and prompt treatment. Applying aspects of BMCs targeted HIV services model in more generalised services such as BGH may be beneficial. Providing adherence support as part of ART services is key to promoting adherence to ART.

RESUMO

BACKGROUND AND STUDY AIMS: Direct percutaneous endoscopic necrosectomy has been described as a minimally invasive intervention for the debridement of walled-off pancreatic necrosis (WOPN). In this retrospective cohort study, we aimed to confirm these findings in a US referral center and evaluate the clinical value of this modality in the treatment of pancreatic necrosis as well as other types of intra-abdominal fluid collections and necrosis. PATIENTS AND METHODS: Twelve consecutive patients with WOPN or other abdominal abscess requiring debridement and washout underwent computed tomography (CT)-guided drainage catheter placement. Each patient then underwent direct percutaneous endoscopic necrosectomy and washout with repeat debridement performed until complete. Drains were then removed once output fell below 30 mL/day and imaging confirmed resolution. The primary endpoints were time to clinical resolution and sustained resolution at 1-year follow up.  RESULTS: Ten patients were treated for WOPN, one for necrotic hepatic abscesses, and one for omental necrosis. The median time to intervention was 85 days with an average of 2.3 necrosectomies performed. Complete removal of drains was accomplished in 11 patients (92 %). The median time to resolution was 57 days. No serious adverse events occurred; however, one patient developed pancreaticocutaneous fistulas. Ten patients completed 1-year surveillance of which none required drain replacement. No patients required surgery or repeat endoscopy. CONCLUSIONS: This series supports the premise that direct percutaneous endoscopic necrosectomy is a safe and effective intervention for intra-abdominal fluid collections and necrosis in appropriately selected patients. Our study demonstrates a high clinical success rate with minimal adverse events. This modality offers several potential advantages over surgical and transgastric approaches including use of improved accessibility, an excellent safety profile, and requirement for only deep or moderate sedation.
