Abstract Background This study aimed to evaluate treatment outcomes and factors associated unsuccessful outcomes among pediatric tuberculosis (TB) patients (age ≤14 years). Methods This was a retrospective cohort study conducted at three districts (Quetta, Zhob and Killa Abdullah) of Balochistan, Pakistan. All childhood TB patients enrolled for treatment at Bolan Medical Complex Hospital (BMCH) Quetta and District Headquarter Hospitals of Zhob and Killa Abdullah from 1 January 2016 to 31 December 2018 were included in the study and followed until their treatment outcomes were reported. Data were collected through a purpose developed standardized data collection form and analyzed by using SPSS 20. A p-value <0.05 was considered statistically significant. Results Out of 5152 TB patients enrolled at the study sites, 2184 (42.4%) were children. Among them, 1941 childhood TB patients had complete medical record were included in the study. Majority of the study participants were <5 years old (66.6%) and had pulmonary TB (PTB; 65%). A total of 45 (2.3%) patients were cured, 1680 (86.6%) completed treatment, 195 (10%) lost to follow-up, 15 (0.8%) died, 5 (0.3%) failed treatment and 1 (0.1%) was not evaluated for outcomes. In multivariate binary logistic regression analysis, treatment at BMCH Quetta (OR = 25.671, p-value < 0.001), rural residence (OR = 3.126, p-value < 0.001) and extra-PTB (OR = 1.619, p-value = 0.004) emerged as risk factors for unsuccessful outcomes. Conclusion The study sites collectively reached the World Health Organization’s target of treatment success (>85%). Lost to follow-up was the major reason for unsuccessful outcomes. Special attention to patients with identified risk factors for unsuccessful outcomes may improve outcomes further.

This is a retrospective cohort study using notification data in South Korea. We evaluated the nationwide status, regional differences, and the determinants of treatment outcomes among tuberculosis patients. Treatment success rate improved from 77.0% in 2012 to 86.0% in 2015. The lost to follow-up rate was higher among older people, males, and foreign nationals. Health care facilities designated for the Public-Private Mix (PPM) project showed higher success rate and lower rate of lost to follow-up. Moreover, municipalities with low regional deprivation index had higher PPM project coverage. Since there is a large regional difference in the coverage of the PPM project, an additional community-based support program should be implemented, especially for tuberculosis patients residing in region with low PPM project coverage.

The Impact

Background: World Health Organization (WHO) (2015) recommended that all people diagnosed with human immunodeficiency virus (HIV)-positive initiate Highly Active Anti Retroviral Therapy (HAART) immediately (less than a week), irrespective of CD4 count (Universal Test and Treat / UTT) Program. Objective: To evaluate the impact of UTT as a current therapeutic program on HIV treatment outcomes, coverage, adherence, and lost to follow-up (LTFU) at Wangaya Hospital in Denpasar, Bali, Indonesia. Methods: A Retrospective cohort study was conducted during July 2017 - June 2018 (Pre-UTT) and September 2018 – August 2019 (Post-UTT). Around 402 medical records were selected, reviewed, and enrolled. Data were analyzed using SPSS software for windows version 24.0. Bivariate analysis (Chi-square test) was performed on all variables with a statistically significant t level of 0.05. Results: Among 4,322 new visitors; 3,585 (82.95%) agreed to take HIV test and 402(11.21%) were confirmed HIV reactive. Most participants confirmed HIV reactive occured at age 25-34 years old and 230 (57.21%) were male. The majority education level were primary (Junior high school) 302(75.12%), 379(94.28%) were employed and 281 (69.90%) stayed in Denpasar. About 350 (87.06%) received HAART, 298 (85.14%) with high adherence and 52 (14.86%) LTFU. Pre-UTT, HAART coverage; 83.03% (181), were statistically significant increased to 91.85% (169) post UTT (p=0.000). High adherence pre-UTT; 79.56% (144) was significantly increased to 91.12% (154) post UTT (p=0.006) and LTFU were significantly decreased; 20.44% (37) to 8.87% (15) (p=0.006). Conclusion: UTT program significantly improve the HIV treatment outcome (increased coverage, adherence, and decreased LTFU).

SETTING: An urban TB diagnostic centre in Lusaka, Zambia.OBJECTIVE: To re-evaluate treatment outcomes of all bacteriologically confirmed TB patients registered in 2018.DESIGN: This was a retrospective cohort study on TB patients. Treatment outcomes of patients who were transferred out were retrieved.RESULTS: A total of 182 patients were registered, 26 of whom had missing documents; these were excluded from the study. Of the remaining 156 patients who were reviewed, 86 (55.1%) were correctly evaluated by the centre, 35 (22.4%) were incorrectly evaluated and 35 (22.4%) were ‘transferred out’ (not evaluated). As a result of this review, the number of evaluated patients increased from 86 (55.1%) to 150 (96.2%). The cure and treatment success rates rose from 43.6% and 44.2%, respectively, to 57.7% and 73.1%, respectively. Of note, 14 of the 35 patients who were initially declared ‘transferred out’ did not actually reach their treatment facilities and ended up being lost to follow-up.CONCLUSION: This study shows that it is possible to evaluate almost all TB patients. Re-evaluation of treatment outcomes of TB patients revealed the problems in the TB services that need to be improved in the future.

Abstract Background Complicated intra-abdominal infections (cIAI) remain an important cause for hospitalization. Evidence-based guidelines recommend reserving broad-spectrum antibiotic coverage for high-risk cases in order to reduce overuse of certain antibiotic classes, particularly in the face of emerging carbapanem resistance. We examined the factors associated with use of empiric carbapenem treatment (ECT) among hospitalized patients with cIAI. Methods We performed a multicenter retrospective cohort study in the Premier database of approximately 180 hospitals, 2013–2017. Using an ICD-9/10 based algorithm including a requirement for a laparotomy/laparoscopy, we identified all adult patients hospitalized with cIAI and included those with a positive blood or abdominal culture. We derived and tested a multivariable logistic regression model to examine predictors of ECT. Results Among 321,317 hospitalized patients with cIAI, 4,453 (1.4%) were culture-positive, 1,185 (26.6%) of whom received ECT. Among those given ECT, >50% (682) had no risk factors for resistance, and in only 120 (10.1%) was an organism resistant to a third-generation cephalosporin (C3R extended spectrum β-lactamase [ESBL] phenotype) isolated. The top 5 variables associated with ECT use were: pre-cIAI anti-fungal therapy (OR 2.57, 95% CI 1.91, 3.45) urgent (vs. emergent) admission (OR 1.56, 95% CI 1.21, 2.01), corticosteroids (OR 1.50, 95% CI 1.13, 1.99), ICU admission (OR 1.46, 95% CI 1.17, 1.82), and presence of sepsis/septic shock (OR 1.43, 95% CI 1.18, 1.74). The model had a moderately good fit (c-statistic = 0.683; 95% CI (0.665, 0.700), Hosmer-Lemeshow P value = 0.411). Conclusion Among patients hospitalized with a cIAI, 26.6% received ECT despite >50% lacking risk factors for resistance, and an only 10% prevalence of C3R in this cohort. This suggests that there remains an opportunity for carbapanem-sparing strategies. Further stratification of the risk for resistance is needed among patients with markers of high illness severity, such as those identified in our model.

Introduction The incidence of non-communicable diseases (NCDs) has been reported to be rising over the years leading up to 2010. In Zimbabwe, there are few studies done to examine the incidence of NCDs in people living with HIV (PLHIV) on anti-retroviral treatment (ART). Objective To determine the incidence of NCDs in HIV patients on ART at the Chitungwiza Central Hospital over ten years and the associated risk factors. Methods This was a retrospective cohort study using data from 203 patients enrolled on ART at the Chitungwiza Central Hospital between 2010 and 2019. All 500 records were considered and the selection was based on participants’ consenting to the study and their strict adherence to ART without absconding. The incidence of NCDs was determined and generalized estimating equations (GEE) were used to estimate the association between NCDs and the selected risk factors. Findings Data collected at the study’s baseline (2010) showed that the most prevalent NCD was hypertension, found in (18/203) 8.9% of the study participants, followed by diabetes (6.9%), then followed by cardiovascular diseases (CVD) (3.9%), and the least common NCD was cancer (1.9%). Incidences of all of these NCDs showed an increasing trend as the time of follow-up progressed. The factors found to be significantly associated with the development of NCDs were gender (p = 0.002) and follow-up time (p<0.001). Geographical location was a significant risk factor as urban patients were more likely to develop hypertension as compared to the peri-urban patients (p = 0.001). Conclusions NCDs and HIV comorbidity is common with women more likely than males to develop NCDs as they advance in age. There is need to devise targeted intervention approach to the respective NCDs and risk factors since they affect differently in relation to the demographic details of the participants. Recommendations This paper recommends a multi-stakeholder approach to the management of NCDs, with researchers, clinicians and the government and its various arms taking a leading role.

Abstract Background The value of follow-up blood cultures (FUBCs) to document clearance of bacteremia due to Gram-negative bacilli (GNB) has not been well established. Although previous studies suggested that the yield of FUBCs for GNB bacteremia is low, it remains to be elucidated for whom FUBC may be beneficial and for whom it is unnecessary. Methods A retrospective cohort study was performed at 4 acute care hospitals to identify risk factors for positive FUBCs with GNB bacteremia and to better guide clinicians’ decisions as to which patients may or may not benefit from FUBCs. Participants included adult patients with GNB bacteremia who had FUBCs and were admitted between January 2017 and December 2018. The primary outcomes were the factors associated with positive FUBCs and the yield of FUBCs with and without the factors. Results Of 306 patients with GNB bacteremia who had FUBCs, 9.2% (95% confidence interval, 6.2%–13.0%) had the same GNB in FUBCs. In the multivariate logistic regression analysis, end-stage renal disease on hemodialysis, intravascular device, and bacteremia due to extended-spectrum β-lactamase or carbapenemase-producing organism were identified as independent predictors of positive FUBCs with GNB bacteremia. Approximately 7 FUBCs and 30 FUBCs were needed for patients with ≥1 or no risk factors, respectively, to yield 1 positive result. SummaryThis multi-site retrospective cohort study found that among patients with gram-negative bacilli (GNB) bacteremia, having ESRD on hemodialysis, intravascular devices, or bacteremia due to multi-drug resistant GNB were each independently associated with having a positive follow-up blood culture. Conclusions Follow-up blood culture may not be necessary for all patients with GNB bacteremia and has the highest yield in patients with 1 or more risk factors.

Abstract Background Recent advances in ulcerative colitis (UC) endoscopic surveillance such as high-definition imaging and greater chromoendoscopy (CE) use have led to an increase in detection and resection of visible dysplasia. An updated study of prognosis of low-grade dysplasia (LGD) is needed to address uncertainty as to the accuracy of progression rates based on historical studies. Methods This retrospective cohort study involved four UK IBD centres. Hospital and endoscopy pathology databases were searched between 1 January 2001 and 30 December 2018 to identify adult patients with UC who had their first LGD diagnosis diagnosed within the extent of colitis. Only patients followed up with at least one colonoscopy or colectomy by 30 August 2019 were included. The study endpoint was time to high-grade dysplasia (HGD) or cancer (CRC), i.e. advanced neoplasia (AN), or end of follow-up. Survival analyses were performed using Kaplan–Meier estimation and Cox proportional hazards (PH) models. Results In total, 460 patients met the inclusion criteria and were followed up for a median of 4.1 years (IQR 6), equating to 2,232 patient-years. A mean of 3.7 (range 0–17) subsequent colonoscopies was performed per patient. Seventy-seven per cent of patients had CE surveillance. Complete endoscopic resection was achieved in 94% and 64% of the polypoid and non-polypoid LGD, respectively. There was progression to AN in 88 cases (19%) during follow-up. There was no significant difference in AN progression between centres. Unresectable non-polypoid or invisible LGD carried the greatest risk of AN development (Figure 1). On univariate Cox PH analysis, CE use was protective against AN progression (HR 0.5; 95% CI 0.3–1.0; p = 0.04). However, only highly significant predictors of LGD progression to AN on univariate analysis (Bonferroni adjusted p &lt; 0.003), were entered into the multivariate model: Cumulative risk of AN increased with the number of risk factors (Figure 2). Conclusion This is the largest study examining prognosis of LGD, based on endoscopic features, in this century. Five-year cumulative incidence of AN is low after complete endoscopic resection of visible LGD without surrounding dysplasia. Lesion size of 1 cm or more, invisibility, multifocality and unresectability of LGD are significant risk factors for progression to AN. These factors should be taken into consideration when discussing management options with patients.

The present study aims towards investigating the risk of developing complications upon usage of different types of contact lens as well as the role played by different variables related to contact lens usage (replacement time, regular follow-up, etc). This is a retrospective cohort study. The total study sample (n = 143) were recruited from Rafha General Hospital, Northern Border Region, Saudi Arabia. All their data were collected and analyzed using chi square test. A <em>P-Value</em> of<em> &lt;</em>0.05 was considered statistically significant. Reusable contact lens wearers were noted to have significantly more complications than disposable contact lens wearers (P<em>&lt;</em>0.05). The majority of the sample was reported to use contact lens for cosmetic (decorative) purpose than for therapeutic or optical indications (<em>63%</em>). Regular follow-up was significantly associated with decrease incidence of contact lens complications (P<em>&lt;</em>0.01). Handling of reusable contact lenses must be done with care as complications are more likely to occur by using them than daily disposable contact lenses. Moreover, contact lens wearers must be advised about the importance of frequent replacement and regular follow-up as it showed significant decrease in complications. We can conclude from our finding that cosmetic usage of reusable contact lenses without proper handling and cleaning system is not advisable.

ObjectivesOpening-wedge high tibia osteotomies (HTO) can be technically challenging. The HTO iBalance system was designed to reduce vascular complications and to avoid secondary plate removal. The purpose of the study was to evaluate the performance of the HTO iBalance system in patients with symptomatic medial osteoarthritis and varus malalignment.MethodsThe study was performed as a retrospective cohort study investigating a consecutive series of patients who underwent HTO with the iBalance system performed by a single surgeon from August 2013 to March 2016 at Zealand University Hospital, Koege, and Aleris-Hamlet Hospital. The primary outcome was the degree of realignment. The secondary outcome was Knee injury and Osteoarthritis Outcome Score (KOOS). Follow-up was performed at mean (SD) 25 (9.7) months. Weight-bearing long-leg standing radiographs were taken before surgery and at follow-up. Failure was defined as collapse of the HTO defined as a correction <50% of the intended correction at time of follow-up. Logistic regression was used to identify risk factors for failure.Results44 patients and a total of 47 knees were included in this study. Preoperatively the mechanical axis was a mean (SD) 5.8° (2.9) varus and postoperatively 2.3° (3.7) varus . The HTO failed in 13 of 47 knees (28%). Patients with failure showed no statistically significant differences to non-failure in any KOOS subscore (p>0.05). American Society of Anesthesiologists (ASA) score (p=0.01) and body mass index (BMI) (p=0.05) were correlated with failure, whereas bone transplantation and smoking were not.ConclusionIn this study, the failure rate of HTO was 28%. High BMI and ASA-score were the only risk factors associated with failure while bone grafting and smoking were not.Level of evidenceRetrospective cohort study, level III.
