Unlabelled: The risk for venous thromboembolism (VTE) is considered to be low in the general paediatric intensive care unit (PICU) population, and pharmacological thromboprophylaxis is not routinely used. PICU patients considered at high-risk of VTE could possibly benefit from pharmacological thromboprophylaxis, but the incidence of VTE in this group of patients is unclear. This was an observational, prospective study at a tertiary multi-disciplinary paediatric hospital. We used comprehensive ultrasonography screening for VTE in critically ill children with multiple risk factors for VTE. Patients admitted to PICU ≥ 72 h and with ≥ two risk factors for VTE were included. Patients receiving pharmacological thromboprophylaxis during their entire PICU stay were excluded. The primary outcome of the study was VTEs not related to the use of a CVC. Ultrasonography screening of the great veins was performed at PICU discharge. Seventy patients with median (interquartile range) 3 (2-4) risk factors for VTE were evaluated. Median age was 0.3 years (0.03-4.3) and median PICU length of stay 9 days (5-17). Regarding the primary outcome, no symptomatic VTEs occurred and no asymptomatic VTEs were found on ultrasonography screening, resulting in an incidence of VTEs not related to a vascular catheter of 0% (95% CI: 0-5.1%).
Conclusion: Our results indicate that VTEs not related to a vascular catheter are a rare event even in a selected group of severely ill small children considered to be at high risk of VTE.
What Is Known: • Children in the PICU often have several risk factors for venous thromboembolism (VTE). • The incidence of VTE in PICU patients is highly uncertain, and there are no evidence-based guidelines regarding VTE prophylaxis.
What Is New: • This study found an incidence of VTEs not related to a vascular catheter of 0% (95% CI: 0-5.1%). • This indicates that such VTE events are rare even in PICU patients with multiple risk factors for VTE.

Clonal haematopoiesis of indeterminate potential and risk of microvascular complications among individuals with type 2 diabetes: a cohort study.
Diabetes

Department of Big Data in Health Science, Zhejiang University School of Public Health and Department of Psychiatry, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, China.
Clonal haematopoiesis of indeterminate potential (CHIP) is associated with macrovascular diseases, including coronary artery disease and stroke. However, the effects of CHIP on microvascular complication have not been evaluated in individuals with type 2 diabetes (T2D). This study included 20,712 T2D participants without prevalent diabetic microvascular complication (DMCs) and hematologic malignancy at baseline.

Importance: Women who use heroin in sub-Saharan Africa face elevated HIV risk linked to structural vulnerability including frequent incarceration. However, little is known about the association between incarceration and drug use and HIV outcomes among women who use heroin in Africa.
Objective: To estimate associations between incarceration and adverse HIV-related and drug use-related outcomes among women who used heroin.

Harvard School of Public Health, Boston, Massachusetts.
Importance: Improving access to high-quality maternity care and reducing maternal morbidity and mortality are major policy priorities in the US. Previous research has primarily focused on access to general obstetric care rather than access to high-risk pregnancy care provided by maternal-fetal medicine subspecialists (MFMs).
Objective: To measure access to MFM services and determine patient factors associated with MFM service use, including MFM telemedicine.

Background: Computed tomography (CT)-derived low muscle mass is associated with adverse outcomes in critically ill patients. Muscle ultrasound is a promising strategy for quantitating muscle mass. We evaluated the association between baseline ultrasound rectus femoris cross-sectional area (RF-CSA) and intensive care unit (ICU) mortality.
