Unlabelled: Ethnic differences in renal calcium and phosphate excretion exist, which may depend on differences in their dietary intakes and regulatory factors. We report highly significant differences in urinary calcium and phosphate excretion between white British and Gambian adults after statistical adjustment for mineral intakes, indicating an independent effect of ethnicity.
Introduction: Populations vary in their risk of age-related osteoporosis. There are racial or ethnic differences in the metabolism of the bone-forming minerals calcium (Ca) and phosphate (P), with a lower renal Ca and P excretion in African-Americans compared to white counterparts, even at similar intakes and rates of absorption. Also, Africans in The Gambia have a lower Ca excretion compared to white British subjects, groups known to differ in their dietary Ca intake. Here, we report on differences in urinary Ca and P excretion between Gambian and white British adults while allowing for known predictors, including dietary intakes.
Methods: Participants were healthy white British (n = 60) and Gambian (n = 61) men and women aged 60-75 years. Fasting blood and 2-h urine samples were collected. Markers of Ca and P metabolism were analysed. Dietary intake was assessed with country-specific methods.
Results: White British older adults had higher creatinine-corrected urinary Ca and P excretion (uCa/uCr, uP/uCr) and lower tubular maximum of Ca and P compared to Gambian counterparts. The predictors of urinary Ca and P differed between groups. Multiple regression analysis showed that dietary Ca and Ca/P were predictors of uCa/uCr and uP/uCr, respectively. Ethnicity remained a significant predictor of uCa/uCr and uP/uCr after adjustment for diet and other factors.
Conclusions: Gambian older adults have higher renal Ca conservation than British counterparts. Dietary mineral intakes were predictors of the differences in urinary Ca and P excretion, but ethnicity remained a highly significant predictor after statistical adjustment. This suggests that ethnicity has an independent effect on renal Ca and P handling.

Coronary CT angiography-guided management of patients with stable chest pain: 10-year outcomes from the SCOT-HEART randomised controlled trial in Scotland.
Lancet

British Heart Foundation Centre of Research Excellence, University of Edinburgh, Edinburgh, UK; Edinburgh Imaging, University of Edinburgh, Edinburgh, UK.
Background: The Scottish Computed Tomography of the Heart (SCOT-HEART) trial demonstrated that management guided by coronary CT angiography (CCTA) improved the diagnosis, management, and outcome of patients with stable chest pain. We aimed to assess whether CCTA-guided care results in sustained long-term improvements in management and outcomes.
Methods: SCOT-HEART was an open-label, multicentre, parallel group trial for which patients were recruited from 12 outpatient cardiology chest pain clinics across Scotland.
Predicting a strongly positive fluid balance in critically ill patients with acute kidney injury: A multicentre, international study.

Background: In critically ill patients with acute kidney injury (AKI), a fluid balance (FB) > 2 L at 72 h after AKI diagnosis is associated with adverse outcomes. Identification of patients at high-risk for such fluid accumulation may help prevent it.
Methods: We used Australian electronic medical record (EMR)-based clinical data to develop the "AKI-FB risk score", validated it in a British cohort and used it to predict a positive FB >2 L at 72 h after AKI diagnosis.
Efficacy of Ozurdex implants as second-line therapy for non-responders to anti-VEGF in retinal vein occlusion-associated macular edema: a retrospective cohort study.

Purpose: Retinal vein occlusion (RVO) is a prevalent retinal vascular disorder characterized by retinal haemorrhage, neovascularization, and macular edema This study aimed to assess the structural and functional effects of intravitreal implant (Ozurdex) treatment as a second-line for RVO-associated macular edema in patients who did not respond to first-line anti-VEGF therapy.
Materials And Methods: We conducted a retrospective observational cohort study using electronic health records of RVO patients at Salisbury District Hospital between January 2014 and December 2019. Inclusion criteria included patients diagnosed with central or branch RVO.
Background: Among individuals with serious mental illness (SMI), victimisation has been found to increase the risk of engaging in other- and self-directed violence. However, rates of victimisation within this population have been found to vary by ethnic group and primary diagnosis.
Aims: This study primarily aimed to examine the relationship between victimisation and other- and self-directed violence among a sample of inpatients with SMI during the first 3 months of admission.

Background: People who inject drugs (PWID) are at increased risk for human immunodeficiency virus (HIV). Women who inject are a particularly vulnerable group. Preexposure prophylaxis (PrEP) is effective, but access and uptake has been limited.
