Assessing the patient safety culture and ward error reporting in public sector hospitals of Pakistan
Background: Very little research and practical efforts have been undertaken in public sector hospitals of Pakistan to promote error reporting and patient safety culture. Nurses in the country are key informants about the climate of error reporting and patient safety standards across wards in the hospital settings. Methods: A questionnaire based on the Hospital Survey on Patient Safety Culture h...
The long QT syndrome affects predominantly younger people who demonstrate structurally normal hearts. The underlying defect in the long QT syndrome seems to be genetic mutations in the cardiac ionic channels responsible for generating action potentials. Genetic linkage mapping has identified six genes (designated LQT1-6) associated with the Romano-Ward syndrome; two of these genes (LQT1, LQT5) ...
BACKGROUND Clostridium difficile infection (CDI) is a leading cause of antibiotic-associated diarrhoea and is endemic in hospitals, hindering the identification of sources and routes of transmission based on shared time and space alone. This may compromise rational control despite costly prevention strategies. This study aimed to investigate ward-based transmission of C. difficile, by subdividi...
AIMS The identification of affected family members with long QT syndrome (LQTS) is often difficult due to their normal-or only marginally lengthened-QT interval duration. We examined whether physical exercise test could increase the ability to detect the mutation carrier status in phenotypically normal LQTS family members. METHODS AND RESULTS Sixty-six subjects were included: 15 were carriers...
Obstructive jaundice in the first months of life is a fairly frequent phenomenon. Approximately twothirds of these infants have atresia of the hepatic ducts, and about two-thirds of the remaining can be classified as 'neonatal hepatitis', 'giant cell hepatitis', or 'thick bile syndrome' (Craig and Landing, 1952; de Toni and Romano, 1962; Gellis, 1961). 'Thick bile syndrome' is defined as 'neona...
We present the Robotic Overlay coMmunicAtioN prOtocol (ROMANO), a lightweight, application layer overlay communication protocol for a unified sensing and control abstraction of a network of heterogeneous robots mainly consisting of low power, low-compute-capable robots. ROMANO is built to work in conjunction with the well-known MQ Telemetry Transport for Sensor Nodes (MQTT-SN) protocol, a light...
Homogeneity of recovery time protects against arrhythmias whereas dispersion of recovery time is arrhythmogenic. A single surface electrocardiographic QT interval gives no information on recovery time dispersion but the difference between the maximum and minimum body surface QT interval may be relevant. This hypothesis was tested by measuring the dispersion of the corrected QT interval (QTc) in...
Background—Transmural dispersion of repolarization (TDR) may be related to the genesis of torsade de pointes (TdP) in patients with the long-QT (LQT) syndrome. Experimentally, LQT2 models show increased TDR compared with LQT1, and -adrenergic stimulation increases TDR in both models. Clinically, LQT1 patients experience symptoms at elevated heart rates, but LQT2 patients do so at lower rates. T...
BACKGROUND A rapidly growing number of long-QT syndrome (LQTS) patients are being treated with an implantable cardioverter-defibrillator (ICD). ICDs may pose problems, especially in the young. We sought to determine the characteristics of the LQTS patients receiving an ICD, the indications, and the aftermath. METHODS AND RESULTS The study population included 233 patients. Beginning in 2002, d...
OBJECTIVES The aim of this study was to elucidate the genetic basis for long QT syndrome (LQTS) in patients with a personal or family history of postpartum cardiac events. BACKGROUND The postpartum period is a time of increased arrhythmogenic susceptibility in women with LQTS. METHODS Between August 1997 and May 2003, 388 unrelated patients (260 females, average age at diagnosis, 23 years, ...
