Can glycated haemoglobin (HbA1c) be used as a predictor of left ventricular diastolic dysfunction in non-hypertensive patients with newly diagnosed type 2 diabetes mellitus: a cross-sectional study at a tertiary care centre in Eastern India.

OBJECTIVES: This study was conducted to establish the association between glycated haemoglobin (HbA1c) and left ventricular diastolic dysfunction (LVDD) in non-hypertensive patients with newly diagnosed type 2 diabetes mellitus (DM) and determine the cut-off value of HbA1c for detecting LVDD. DESIGN: Cross-sectional study. SETTING: This study was conducted in General Medicine Department in collaboration with the Cardiology Department at All India Institute of Medical Sciences, Patna. PARTICIPANTS: The study population comprised patients with newly diagnosed type 2 DM within the past 3 months, aged between 18 years and 80 years, who were not hypertensive and without any systemic diseases and who presented to the General Medicine Department. PRIMARY AND SECONDARY OUTCOME MEASURES: The presence of LVDD was the primary outcome measure. RESULTS: Among the total of 60 participants, it was observed that age (adjusted odds ratio (AOR): 1.169, 95% CI: 1.066 to 1.283) and HbA1c (AOR: 2.625, 95% CI: 1.264 to 5.450) were found to be independent predictors for the presence of LVDD. Receiver operating characteristic analysis identified a cut-off value of HbA1c at 9.5% (80 mmol/mol) for detecting LVDD, with a specificity of 96.43%, a sensitivity of 37.5% and a positive predictive value (PPV) of 91.62%. CONCLUSIONS: This study demonstrated that age and HbA1c levels are independent predictors of LVDD in patients with newly diagnosed type 2 DM without hypertension. A cut-off value of 9.5% for HbA1c was identified with a high specificity and PPV for predicting LVDD in patients with newly diagnosed type 2 diabetes. This underscores the importance of conducting echocardiography in patients with newly diagnosed asymptomatic type 2 diabetes with HbA1c 9.5% or more to assess LVDD, allowing for prompt interventions if necessary and to decelerate the progression towards heart failure.

Classic paroxysmal nocturnal haemoglobinuria presenting with intestinal malabsorption syndrome, acute abdomen and acute kidney injury.

A male patient in his 30s presented with complaints of acute abdominal pain, black stools and red-coloured urine. CT revealed thrombi in the splenic and left renal veins, leading to infarctions. An endoscopy displayed scalloping of the duodenal folds, indicative of intestinal malabsorption syndrome (IMS). Histopathological examination confirmed IMS. Due to the presence of intravascular haemolysis, haemoglobinuria and thrombotic complications, paroxysmal nocturnal haemoglobinuria (PNH) was suspected and subsequently confirmed by flow cytometry. Thus, a diagnosis of classic PNH with IMS and thrombotic complications was established. This unique case highlights the coexistence of PNH and IMS, resembling the complement hyperactivation, angiopathic thrombosis and protein-losing enteropathy disease, suggesting potential shared pathophysiology.

Efficacy of Interventions Based on WHO Multimodal Hand Hygiene Improvement Strategy in a Tertiary Care Hospital in Eastern India: A Quasi-Experimental Study.

The study aimed to evaluate the efficacy of the World Health Organization (WHO) multimodal hand hygiene improvement (WHO-5) strategy in enhancing hand hygiene compliance among health care workers at a tertiary care hospital. The interrupted time series study included preintervention, intervention, and postintervention phases, with 2 points of observation each during the pre- and postintervention phases. The baseline hand hygiene compliance was 16%, which improved to 43.9% after the intervention. Health care workers were 4 times more likely to adhere to proper hand hygiene postintervention (odds ratio [OR], 4.117). Independent predictors of hand hygiene compliance included the week of observation (week 3: adjusted odds ratio [AOR], 0.872; week 5: AOR, 3.427; and week 7: AOR, 4.713), health care worker type (consultants: AOR, 0.964; residents: AOR, 2.187; and interns: AOR, 6.684), daytime (AOR, 1.232), and "after" type of hand hygiene opportunity (AOR, 1.577). No significant differences were found in knowledge, attitude, and practices pre- and postintervention, and the interventions' effect was sustained and increased over time, supporting implementation in hospitals across India.
