Abstract Introduction During critical illness, oliguria is often used as a biomarker of acute kidney injury (AKI). However, its relationship with the subsequent development AKI has not been prospectively evaluated. Methods We documented urine output and daily serum creatinine concentration in patients admitted for more than 24 hours seven intensive care units (ICUs) from six countries over period two to four weeks. Oliguria was defined by < 0.5 ml/kg/hr. Data were collected until...

OBJECTIVES: Little is known about the effect of physical activity on diverticular complications. This study prospectively examined associations between and bleeding diverticulitis. METHODS: We studied 47,228 US males in Health Professionals Follow-up Study cohort who were aged 40-75 years free disease, gastrointestinal cancer, inflammatory bowel disease at baseline 1986. Men reporting newly diagnosed biennial follow-up questionnaires sent supplemental outlining details diagnosis treatment....

Summary We proposed that many Intensive Care Unit (ICU) patients would be hypothermic in the early postoperative period and hypothermia associated with increased mortality. retrospectively reviewed admitted to ICU after surgery. recorded lowest temperature first 24 h surgery using tympanic membrane thermometers. defined as < 36 °C, severe 35 °C. studied 5050 consecutive patients: 35% were 6% severely hypothermic. In‐hospital mortality was 5.6% for normothermic patients, 8.9% all (p...

A renal vascular coordinator (RVC) is a single point-of-contact allied health professional in the early detection and timely intervention of flow dysfunction. In Khoo Teck Puat Hospital (KTPH), RVC performs access ultrasonography assessment assists reviewing direct referrals about dysfunctional arteriovenous fistula (AVF)/arteriovenous graft (AVG) from community dialysis centres plans for appointments with interventional nephrologists surgeons. We conducted prospective study April 2020 to...

Blood pressure is an important determinant of renal perfusion and acute kidney injury (AKI) common in hospital patients. However, there limited knowledge concerning the incidence relative hypotension prior to its development general wards.We compared blood recordings a cohort consecutive patients with no change function changes according RIFLE classes R, I F for AKI. We assessed over 3-day period before AKI index similar controls. excluded absolute [systolic (SBP) <90 mmHg].Patients were old...

Randomized controlled trials have demonstrated the benefits of sodium-glucose cotransporter 2 inhibitors (SGLT2is) in people with type diabetes mellitus (T2DM) and chronic kidney disease (CKD). However, real-world data on CKD progression development end-stage (ESKD) remains scarce. Our aim was to study renal outcomes diabetic (DKD) using SGLT2is a highly prevalent DKD population.Between 2016 2019 we recruited T2DM patients clinics regional hospital Singapore. Patients prescribed were...

In the present study, we examined association between HbA1c variability and renal disease progression based on estimated glomerular filtration rate (eGFR) decline in patients with type 2 diabetes mellitus (T2DM) Singapore.Glycemic burden function were retrospectively assessed 1628 2002-2014. Multivariable logistic regression was used to assess relationships (expressed as coefficient of variation [HbA1c-CV] quartiles), intrapersonal mean (HbA1c-IM), eGFR decline, adjusted for baseline...

Abstract Background Fluid assessment is challenging, and fluid overload poses a significant problem among dialysis patients, with pulmonary oedema being the most serious consequence. Our study aims to develop simple objective strategy using lung ultrasound (LUS) artificial intelligence (AI) assess status of patients. Methods This was single-centre 76 hemodialysis peritoneal patients carried out between July 2020 May 2022. The assessed via simplified 8-point LUS method portable handheld...

Glomerular hyperfiltration usually occurs early in development of kidney complications diabetes. To understand as a marker renal disease progression type 2 diabetes mellitus, we aimed to examine association between glomerular (estimated filtration rate ⩾ 120 mL/min/1.73 m2) and rapid decline (annual estimated loss 3 m2).This was prospective cohort comprising 1014 patients with mellitus attending Diabetes Centre regional hospital 2002-2014. A separate cohort, 491 who attended or primary-care...

Fluctuation of kidney function may signify intra-glomerular microvascular hemodynamic instability. We aim to examine the association long-term serum creatinine and estimated glomerular filtration rate variability with diabetic retinopathy.We included type 2 diabetes mellitus patients who attended Diabetes Centre in 2011-2014 were followed up (median = 3.2 years). Digital colour fundus photographs assessed for retinopathy at follow-up. Diabetic severity was categorized into non-proliferative...

To characterize haemoglobin A1c (HbA1c) trajectories and examine their associations with chronic kidney disease (CKD) progression.This was a prospective cohort study on 770 patients type 2 diabetes mellitus (T2DM) attending centre in 2002-2017. Group-based trajectory modelling used to identify HbA1c trajectories. Cox proportional hazards models were association between the CKD progression which defined as deterioration across Kidney Disease: Improving Global Outcomes estimated glomerular...
