Introduction:Delay in the diagnosis of tuberculosis (TB) can lead to an increased infectivity period, delayed treatment, and increased severity of the disease. The objective of this study was to estimate the diagnostic delay and factors associated with the delay in diagnosis among the newly diagnosed smear-positive pulmonary TB patients in Kerala, India.Materials and Methods:A cross-sectional study was conducted among TB patients who were in the intensive phase of directly observed treatment short-course treatment in four randomly selected TB units in a district in Kerala during the years 2012–2013. Diagnostic delay was defined as the delay between the onset of symptoms and diagnosis. Data collection using a modified World Health Organization questionnaire was done by interviewing 302 participants.Results:Mean age of the participants was 48.6 ± 14.5 years. Males constituted 76.5% of the study population. The mean diagnostic delay was 43.5 ± 29.1 days (median: 37 days). The median patient and health system delays were 16 days and 15 days, respectively. Patient delay (55.6%) contributed more than health system delay (44.4%). Poor knowledge about TB, first consulting a private physician, and increased number of consultations were found to be significantly associated with diagnostic delay.Conclusion:The diagnostic delay in tuberculosis reported in this study was lower than other studies in India but it needs further reduction. Both patients and health providers play a role in a delay in diagnosis, and poor knowledge about the disease among the patients was one of the main risk factors. Interventions to improve knowledge and awareness of the disease and to increase the suspicion of chest symptomatic by health-care providers in the private sector are vital to reduce diagnostic delay.

Safety of parenteral iron therapy is critical and has been demonstrated in several studies, but concerns persist on safety. We performed a retrospective single-center study investigating the safety and efficacy of parenteral iron administration using 2 iron preparations-Monofer and Cosmofer (Pharmacosmos A/S, Holbaek, Denmark)-in patients with chronic kidney disease (CKD), on peritoneal dialysis (PD) and non-dialysis. A database of CKD patients receiving intravenous (IV) iron was analyzed. Side effects were recorded during infusion, post-infusion, and after 48 hours. In a population of CKD patients (non-dialysis and PD), IV iron is safe with few major adverse effects for these 2 IV iron preparations studied with similar dosing schedules. These data provide reassurance on the relative short-term safety of IV iron preparations regarding acute infusion-related hypersensitivity reactions.

Background This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. Methods This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score‐matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score‐matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. Results A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score‐matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). Conclusion There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast‐induced nephropathy should not be used as a reason to avoid contrast‐enhanced CT.
