    Two hundred and sixty four samples of ready -to-eat foods (RTE) were obtained over a period of six months (April to September 2005) from 33 school hostel kitchens and canteens previously implicated in food poisoning outbreaks from 2000 to 2004. Sampling was done by food technologists and assistant environmental health ofhcers from various districts in Pahang while microbiological analysis was carried out at the Mentakab Food Quality Control Laboratory. The objective of the study was to obtain a comprehensive picture on the microbiological status of the foods that may have accounted for food poisoning outbreaks at school hostels and canteens in Pahang. Each food sample was analyzed for Total Plate Count (TPC), Salmonella, Coliform, Escheria coli, Staphylococcus aerus and Bacillus cereus. lt was found that none of the ready-to-eat foods sampled contained Salmonella although hve samples contained Bacillus cereus , four samples contained Staphylococcus aerus. High Coliform Counts were found in 15 food samples while Escheria coli was detected in two samples. Overall, it was found that 10.2 % of the samples had unsatisfactory counts.

    BACKGROUND: Different iterations of catheter and energy delivery system configurations are evolving for pulsed field ablation (PFA); however, some have used large and complex catheters, required large sheaths, and had a recognized risk of hemolysis.

    OBJECTIVE: The purpose of this study was to evaluate the acute safety and efficacy of a custom designed 8F variable loop multielectrode mapping and PFA catheter with contact sensing.

    METHODS: This acute feasibility study recruited 30 patients undergoing de novo ablation of paroxysmal or persistent atrial fibrillation (AF). The ElectroPulse Study is a first-in-human, nonrandomized, prospective study of a novel PFA system that utilizes an 8F, 10-electrode variable loop steerable mapping and ablation catheter with 2800-V biphasic bipolar waveform. All patients had pulmonary vein isolation (PVI) and posterior wall isolation (PWI) using the PFA system. The main outcomes were the acute success of PV/PWI and periprocedural serious adverse events.

    RESULTS: Complete PVI/PWI was successfully achieved in all 30 patients using 59.7 ± 7.2 applications. Total procedural time was 113.6 ± 26.3 minutes, fluoroscopy time 8.0 ± 5.5 minutes, and left atrial dwell time 78.7 ± 18.6 minutes. There was no esophageal injury, phrenic nerve palsy, clinical stroke, or death. Brain magnetic resonance imaging detected 2 new but transient silent cerebral lesions. Two patients (6.7%) had vascular access complications. Although there were changes in the biomarkers for hemolysis, none of the patients experienced clinical hemolysis or related acute kidney injury.

    CONCLUSION: This first-in-human study demonstrated that PFA using a novel variable loop catheter with a contact sensing system safely achieved 100% acute PVI/PWI with safety profile comparable to existing PFA systems.

    BACKGROUND: Inpatient monitoring is recommended for sotalol initiation.

    OBJECTIVE: The purpose of this study was to assess the safety of outpatient sotalol commencement.

    METHODS: This is a multicenter, retrospective, observational study of patients initiated on sotalol in an outpatient setting. Serial electrocardiogram monitoring at day 3, day 7, 1 month, and subsequently as clinically indicated was performed. Corrected QT (QTc) interval and clinical events were evaluated.

    RESULTS: Between 2008 and 2023, 880 consecutive patients who were commenced on sotalol were evaluated. Indications were atrial fibrillation/flutter in 87.3% (n = 768), ventricular arrhythmias in 9.9% (n = 87), and other arrhythmias in 2.8% (n = 25). The daily dosage at initiation was 131.0 ± 53.2 mg/d. The QTc interval increased from baseline (431 ± 32 ms) to 444 ± 37 ms (day 3) and 440 ± 33 ms (day 7) after sotalol initiation (P < .001). Within the first week, QTc prolongation led to the discontinuation of sotalol in 4 and dose reduction in 1. No ventricular arrhythmia, syncope, or death was observed during the first week. Dose reduction due to asymptomatic bradycardia occurred in 3 and discontinuation due to dyspnea in 3 within the first week. Overall, 1.1% developed QTc prolongation (>500 ms/>25% from baseline); 4 within 3 days, 1 within 1 week, 4 within 60 days, and 1 after >3 years. Discontinuation of sotalol due to other adverse effects occurred in 41 patients within the first month of therapy.

    CONCLUSION: Sotalol initiation in an outpatient setting with protocolized follow-up is safe, with no recorded sotalol-related mortality, ventricular arrhythmias, or syncope. There was a low incidence of significant QTc prolongation necessitating discontinuation within the first month of treatment. Importantly, we observed a small incidence of late QT prolongation, highlighting the need for vigilant outpatient surveillance of individuals on sotalol.

    BACKGROUND: Athletes have changes that can mimic pathological cardiomyopathy.

    METHODS: Echocardiographic study of 50 male, female athletes (MA, FA) and non-athletes (MNA, FNA) age 18 to 30 years. These athletes participate in sports with predominantly endurance component. All participants exhibit no known medical illnesses or symptoms.

    RESULTS: MA have thicker wall (IVSd) than MNA. No MA have IVSd > 1.2 cm and no FA have IVSd > 1.0 cm. Left ventricle internal dimension (LVIDd), left ventricle end diastolic volume index (LVEDVi) is bigger in athletes. None have LVIDd > 5.8 cm. Right ventricle fractional area change (FAC) is lower in athletes. (MA vs MNA, p = 0.013, FA vs FNA, p = 0.025). Athletes have higher septal and lateral e' (Septal e'; MA 13.57 ± 2.66 cm/s vs MNA 11.46 ± 2.93 cm/s, p  1.2 cm and/or LVIDd > 5.8 cm. There is no difference in GLS, RVFWS and GCS but athletes have smaller LArS and LAbS.
