    "Occupational MDR-TB"  …  "XDR-TB"  …  "Treatment-induced hearing loss": 3 life-changing messages imparted over the phone. Three personal accounts are shared highlighting the false belief held by many healthcare workers (HCWs) and students in low-resource settings-that they are immune to tuberculosis despite high levels of occupational tuberculosis exposure. This misconception reflects a lack of awareness of tuberculosis transmission and disease risk, compounded by the absence of accurate occupational tuberculosis estimates. As the global problem of drug-resistant (DR) tuberculosis evolves, HCWs are increasingly infected and suffer considerable morbidity and mortality from occupational DR tuberculosis disease. Similarly, healthcare students are emerging as a vulnerable and unprotected group. There is an urgent need for improved detection, vaccines, preventive therapy, treatment, and support for affected HCWs and those they care for, as well as destigmatization of all forms of tuberculosis. Finally, efforts to protect HCWs and prevent DR tuberculosis transmission by universal implementation of tuberculosis infection control measures should be prioritized.

    PURPOSE: Incidence, management, and outcomes of pediatric vascular injuries secondary to non-iatrogenic trauma were reviewed over a decade in our institution.

    METHODS: A retrospective review of medical records (2013-2022) of major traumatic vascular injuries, focusing on injury profiles, treatment modalities, and clinical outcomes.

    RESULTS: Thirty patients with 48 vessel injuries were included. Firearms were the leading mechanism, accounting for 43.3% (n = 13) of cases. We identified 29 arterial injuries and 19 venous injuries, with 30 (62.5%) of the overall injuries occurred in the lower extremities. Shock (17; 56.7%) and associated injuries (25; 83.3%) were common. Surgery was the most common management strategy. Autologous bypass graft was the most frequently performed procedure for arterial injuries (8; 42.1%), while ligation dominated in venous injuries (9; 64.3%). Blood transfusion requirements (24; 82.7%) and post-operative prescription of anticoagulant and antiplatelet agents (12; 41.4%) were similar for arterial and venous injuries (p > 0.05). Three patients demised, resulting in a 90% survival rate. Neither the mechanism of injury, anatomical location, and presence of shock on arrival nor the baseline hemoglobin level served as predictors of mortality.

    CONCLUSION: Intensive resuscitation with blood transfusion and prompt surgical intervention achieve favorable survival rates for pediatric traumatic vascular injuries. Optimal post-operative anticoagulant and antiplatelet regimens remain unclear.

  3. Fulltext Agents of change: The role of healthcare workers in the prevention of nosocomial and occupational tuberculosis

    Healthcare workers (HCWs) play a central role in global tuberculosis (TB) elimination efforts but their contributions are undermined by occupational TB. HCWs have higher rates of latent and active TB than the general population due to persistent occupational TB exposure, particularly in settings where there is a high prevalence of undiagnosed TB in healthcare facilities and TB infection control (TB-IC) programmes are absent or poorly implemented. Occupational health programmes in high TB burden settings are often weak or non-existent and thus data that record the extent of the increased risk of occupational TB globally are scarce. HCWs represent a limited resource in high TB burden settings and occupational TB can lead to workforce attrition. Stigma plays a role in delayed diagnosis, poor treatment outcomes and impaired well-being in HCWs who develop TB. Ensuring the prioritization and implementation of TB-IC interventions and occupational health programmes, which include robust monitoring and evaluation, is critical to reduce nosocomial TB transmission to patients and HCWs. The provision of preventive therapy for HCWs with latent TB infection (LTBI) can also prevent progression to active TB. Unlike other patient groups, HCWs are in a unique position to serve as agents of change to raise awareness, advocate for necessary resource allocation and implement TB-IC interventions, with appropriate support from dedicated TB-IC officers at the facility and national TB programme level. Students and community health workers (CHWs) must be engaged and involved in these efforts. Nosocomial TB transmission is an urgent public health problem and adopting rights-based approaches can be helpful. However, these efforts cannot succeed without increased political will, supportive legal frameworks and financial investments to support HCWs in efforts to decrease TB transmission.
