Abstract Background: Despite, antiretroviral therapy could reduce the transmission of human immunodeficiency virus and related morbidity, loss to follow up is a main challenge among children living with human immunodeficiency virus. Therefore, the aim of this study was to assess the incidence and predictors of loss to follow up among under 15 years old children attending antiretroviral therapy clinic at Dessie referral hospital, North east Ethiopia.Methods: A ten-year institution based retrospective cohort study was employed among 448 under 15 years’ old children who were enrolled on antiretroviral therapy. Data were entered and cleared using Epi- data version 3.1 and then exported to STATA version 14 for further statistical analysis. Kaplan Meier survival curve was used to estimate the survival time and log rank test was used to compare the survival time between different categories of the explanatory variables. Multivariable Cox proportional hazards model was fitted to identify predictors of loss to follow up and p-value < 0.05 was considered as statically significant.Results: The overall incidence rate of loss to follow up was 6.3 per100 children in years of observation. Being male (AHR=2.1, CI =1.37 ,3.34), age 1-5 years (AHR=1.6, CI=1.05,2.46), poor adherence to antiretroviral therapy (AHR = 6.6; CI=4.11,10.66), fair adherence to antiretroviral therapy (AHR= 2.2; CI = 1.13 ,4.20), regimen was not changed (AHR = 4.1; CI = 2.59 ,6.45), world health organization stage III and IV (AHR= 2.2; CI =1.40, 3.33) and height for age < -2 z score (AHR = 2.2; CI = 1.43, 3.44) were predictors of loss to follow up.Conclusion: The incidence rate of loss to follow was high. Age 1-5 years, world health organization stage III and IV, poor and fair adherence to antiretroviral therapy, regimen was not changed, being male and stunted were higher risk for loss to follow up. Therefore, close monitoring to the higher risk groups for loss to follow up highlighted in this study could decrease the rate of loss to follow up. Improving the adherence of children to antiretroviral therapy and nutritional support for stunted children were also recommended.

Abstract Background: Tuberculosis is the leading cause of morbidity and mortality among people living with human immunodeficiency virus. Almost one-third of deaths among people living with human immunodeficiency virus are attributed to tuberculosis. Despite this fact, in Ethiopia, particularly in our study area there is a scarcity of information regarding the incidence and predictors of TB among peoples living with HIV. Thus, this study aimed to assess the incidence and predictors of tuberculosis among HIV positive adults. Methods: An institution based retrospective cohort study was conducted among 544 HIV-positive adults on ART at Debre Markos Referral Hospital from January 1, 2012 to December 31, 2017. The study participants were selected using a simple random sampling technique. The data extraction format was adapted from ART intake and follow-up forms. Data were entered using Epi-Data version 4.2 and analyzed using STATA Version 13. Tuberculosis free survival time was estimated using the Kaplan-Meier survival curve. Both the bi-variable and multivariable Cox-proportional hazard regression models were used to identify predictors of the time to develop TB. Results: Among 492 HIV-positive adults included in the final analysis, 16.9% of them developed TB at the time of follow up. The incidence rate of TB was found to be 6.5 (95%CI: 5.2, 8.0) per 100-person years. Advanced WHO clinical disease stage (III and IV) (AHR: 2.1, 95% CI: 1.2, 3.2), being ambulatory and bedridden (AHR: 1.8, 95% CI: 1.1, 3.1), baseline opportunistic infections (AHR: 2.8, 95% CI: 1.7, 4.4), low hemoglobin level (AHR: 3.5, 95% CI: 2.1, 5.8), and not taking IPT (AHR: 3.9, 95% CI: 1.9, 7.6) were found to be predictors of the time to develop TB. Conclusion: In this study, a high incidence rate of TB was observed among HIV-positive adults. Advanced HIV disease stage (III and IV), being ambulatory and bedridden, having opportunistic infections, having a low hemoglobin level, and not taking IPT were found to be predictors of the time to develop TB.

Abstract Background: Although stroke is an uncommon but life-threatening complication among spinal surgery patients, the recognition of this adverse event is critical given the aging population undergoing surgical procedures. The objective of this study was to estimate the incidence of stroke among adults undergoing elective posterior lumbar fusion (PLF) during post-operative risk windows and among different subgroups. Methods: A retrospective cohort study using a longitudinal electronic healthcare record (EHR) database was conducted from January 1, 2007 to June 30, 2018. Elective PLF, stroke, and select clinical characteristics were defined based on International Classification of Disease codes. Patients aged 18 to 85 years with ≥ 183 days of enrollment in the database prior to undergoing elective PLF were followed from the index date until the occurrence of stroke, death, loss to follow-up, or end of study period, whichever occurred first. Incidence proportions (IPs) and rates (IRs) of stroke were estimated in the following risk windows: index hospitalization, ≤ 30 days, ≤ 90 days, ≤ 180 days, and ≤ 365 days post-operation Results: A total of 43,063 patients were eligible for the study. The IP of stroke following elective PLF ranged from 0.29% (95% confidence interval [CI]: 0.25%, 0.35%) during index hospitalization to 1.12% (95% CI: 1.03%, 1.23%) ≤ 365 days post-operation; the IR of stroke following elective PLF per 1000 person-years decreased consistently from 229.08 (95% CI: 192.38, 272.78) during index hospitalization to 13.68 (95% CI: 12.51, 14.96) ≤ 365 days post-operation. Stratified analyses revealed that older patients had a higher incidence of stroke. Additionally, black patients had higher stroke incidences than white, Asian, or other patients. Furthermore, the incidence of post-operative stroke was higher among patients with a history of type 2 diabetes than among patients without such history. Conclusions: The incidence of stroke following elective PLF found here using an EHR database is slightly higher than that reported in the literature; however, the discrepancy is due to differences in the variable definitions, study populations, follow-up periods, and data sources between our study and those in the literature.

Abstract Background Why some persons living with human immunodeficiency virus (HIV) (PLWH) progress quickly and others remain “healthy” for a decade or more without treatment remains a fundamental question of HIV pathology. We aimed to assess the epidemiological characteristics of HIV long-term nonprogressors (LTNPs) based on a cohort of PLWH in China observed between 1989 and 2016. Methods We conducted a nationwide, retrospective cohort study among Chinese PLWH with HIV diagnosed before 1 January 2008. Records were extracted from China’s national HIV/AIDS database on 30 June 2016. LTNPs were defined as those with AIDS-free, antiretroviral therapy–naive survival, with CD4 cell counts consistently ≥500/μL for ≥8 years after diagnosis. Prevalence was calculated, characteristics were described, and determinants were assessed by means of logistic regression. Potential sources of bias were also investigated. Results Our cohort included 89 201 participants, of whom 1749 (2.0%) were categorized as LTNPs. The injection drug use (IDU) route of infection was reported by 70.7% of LTNPs, compared with only 37.1% of non-LTNPs. The odds of LTNP status were greater among those infected via IDU (adjusted odds ratio [95% confidence interval], 2.28 [1.94–2.68]) and with HIV diagnosed in settings with large populations of persons who inject drugs (1.75 [1.51–2.02] for detention centers, 1.61 [1.39–1.87] for Yunnan, 1.94 [1.62–2.31] for Guangdong, and 2.90 [2.09–4.02] for Xinjiang). Conclusions Overrepresentation of the IDU route of infection among LTNPs is a surprising finding worthy of further study, and this newly defined cohort may be particularly well suited to exploration of the molecular biological mechanisms underlying HIV long-term nonprogression.

Abstract Background Pastoralist communities are known to be hard to reach. The magnitude of temporary disengagement from human immunodeficiency virus (HIV) care is understudied. Methods We conducted a retrospective cohort study of temporary disengagement (2 weeks late for a next appointment), virologic response, lost to follow-up (6 months late) and re-engagement in care among patients who started antiretroviral therapy between 2014 and 2016 in Baringo County, Kenya. Predictors of re-engagement after disengagement were estimated using logistic regression. Results Of 342 patients, 76.9% disengaged at least once (range 0–7). Of 218 patients with a viral load (VL), 78.0% had a suppressed VL. Those with a history of temporary disengagement from care were less likely to suppress their VL (p=0.002). Six patients had treatment failure (two consecutive VLs &gt;1000 copies/mm3) and all had disengaged at least once. After disengagement from care, male patients (adjusted odds ratio [aOR] 0.3 [95% confidence interval {CI} 0.2 to 0.6]; p&lt;0.001) and patients with World Health Organization stage III–IV (aOR 0.3 [95% CI 0.1 to 0.5; p&lt;0.001) were less likely to re-engage in care. Conclusions Temporary disengagement was frequent in this pastoralist setting. This indicator is often overlooked, as most studies only report binary outcomes, such as retention in care. Innovative strategies are required to achieve HIV control in rural settings like this pastoralist setting.
