Background: Follow-up scoliosis radiographs are performed to assess the degree of spinal curvature and skeletal maturity, which can be done at lower radiation exposures than those in standard-dose radiography. Objective: Describe and evaluate a protocol that reduced the radiation in follow-up frontal-view scoliosis radiographs. Materials and methods: We implemented a postero-anterior lower dose modified-technique for scoliosis radiography with task-based definition of adequate image quality and use of technique charts based on target exposure index and patient's height and weight. We subsequently retrospectively evaluated 40 consecutive patients who underwent a follow-up radiograph using the modified-technique after an initial standard-technique radiograph. We evaluated comparisons of proportions for subjective assessment with chi-squared tests, and agreements of reader's scores with intraclass correlation coefficients and Bland–Altman plots. We determined incident air kerma, exposure index, deviation index/standard deviation, dose-area product (DAP), and effective dose for each radiograph. We set statistical significance at P<0.05. Results: Forty patients (65% female), aged 4–17 years. Median effective dose was reduced from 39 to 10 µSv (P<0.001), incident air kerma from 139 to 29 µSv (P<0.001), and DAP from 266 to 55 mGy*cm2 (P<0.001). All modified-technique parameters were rated with a mean score of acceptable or above. All modified-technique measurements obtained inter- and intra-observer correlation coefficient agreements of 0.86 ("Good") or greater. Conclusion: Substantial dose reduction on follow-up scoliosis imaging with existing radiography units is achievable through task-based definition of adequate image quality and tailoring of radiation to each patient's height and weight, while still allowing for reliable assessment and reproducible measurements.

Purpose: SIGN Fracture international is a non-profit organization that provides intramedullary nails to SIGN centres at no cost for intra-operative fracture fixation in exchange for cases being uploaded to the SIGN Online Surgical Database (SOSD). The SIGN program was introduced in Zimbabwe in 2013 and had expanded to nine hospitals at the end of 2020. This study aimed to evaluate the population characteristics and clinical outcomes of patients who received the SIGN nail in Zimbabwe as well as intranational trends across SIGN centres. Methods: We conducted a retrospective review of the SOSD for all cases carried out in Zimbabwe between 2013 and 2020. Results: A total of 1764 patients received operative fixation over the period. The majority were young (36.83 ± 15.13) years and male (74%). The average time to surgery was 22 ± 20.5 days with over 69% of patients getting surgery after more than ten days. Femur fracture fixation (72%) was the most common procedure with road traffic accidents (RTAs) being the most common cause of fractures (73%). The majority of patients had no follow-up (61%). Of patients with follow-up, 4% reported infection, 2% deformity, and 78% with healing X-rays. There were large differences in volume of patients at different centres with no significant trends in outcomes. Conclusion: The SIGN program allows for safe surgery in Zimbabwe. There are large intranational differences of no particular trend across SIGN centres which may be improved through more intranational knowledge sharing. Improved follow-up would allow for more insights to be gleaned from the database. [ABSTRACT FROM AUTHOR]

Purpose: Although motorcycle accidents are a leading cause of limb injury in Uganda, little is known about injury care quality at regional hospitals. This study measured the incidence of clinical adverse events (CAEs) and identified associated treatment barriers surrounding motorcycle-related isolated limb injuries at a regional hospital. Methods: A prospective descriptive study was conducted among patients with motorcycle-related isolated limb injuries at a Ugandan regional hospital between September 2017 and February 2018. Patients were surveyed upon admission and monitored throughout their course of treatment. Weight-bearing status and quality of life measures (EQ-5D) were assessed at four and 12 weeks. Results: One hundred twenty-four participants enrolled. Of the total participants, 12% refused definitive treatment. Among 108 treated patients, six experienced CAEs: four wound infections, one amputation, and one death. At 12 weeks follow-up, the majority of patients had no difficulty with mobility, pain/discomfort, or self-care, but 51% endorsed challenges completing certain daily chores, and 40% of patients could ambulate without an assistive device with restoration of pre-fracture gait. Both longer hospital stays and poorer 12-week functional recovery were seen among patients sustaining open fracture (p < 0.001). Conclusion: Treatment of isolated limb injuries at a Ugandan Regional Hospital was associated with minimal short-term CAEs. However, patients with more severe injuries may be at risk for delayed post-operative recovery. Future studies measuring long-term functional outcomes should be performed to better understand and optimize injury care in this population. [ABSTRACT FROM AUTHOR]

We found that comprehensive, integrated, community-based intervention (characterized by daily home visits from a community health worker, directly observed treatment, nutritional support, and transportation stipends) was associated with higher antiretroviral therapy retention at 1 year among adults in rural Rwanda.Background. Minimizing death and ensuring high retention and good adherence remain ongoing challenges for human immunodeficiency virus (HIV) treatment programs. We examined whether the addition of community-based accompaniment (characterized by daily home visits from a community health worker, directly observed treatment, nutritional support, transportation stipends, and other support as needed) to the Rwanda national model for antiretroviral therapy (ART) delivery would improve retention in care, viral load suppression, and change in CD4 count, relative to the national model alone.Methods. We conducted a prospective observational cohort study among 610 HIV-infected adults initiating ART in 1 of 2 programs in rural Rwanda. Psychosocial and clinical characteristics were recorded at ART initiation. Death, treatment retention, and plasma viral load were assessed at 1 year. CD4 count was evaluated at 6-month intervals. Multivariable regression models were used to adjust for baseline differences between the 2 populations.Results. Eighty-five percent and 79% of participants in the community-based and clinic-based programs, respectively, were retained with viral load suppression at 1 year. After adjusting for CD4 count, depression, physical health quality of life, and food insecurity, community-based accompaniment was protective against death or loss to follow-up during the first year of ART (hazard ratio, 0.17; 95% confidence interval [CI], .09–.35; P < .0001). In a second multivariable analysis, individuals receiving accompaniment were more likely to be retained with a suppressed viral load at 1 year (risk ratio: 1.15; 95% CI, 1.03–1.27; P = .01).Conclusions. These findings indicate that community-based accompaniment is effective in improving retention, when added to a clinic-based program with fewer patient support mechanisms. [ABSTRACT FROM AUTHOR]
