Echocardiographic based cardiac evaluation in children with severe acute malnutrition.

OBJECTIVE: To identify echocardiography-based myocardial changes in children with severe acute malnutrition. Methods: The prospective study was conducted from January to November 2020 at a territory care paediatric hospital in Multan, Pakistan, and comprised severe acute malnutrition patients of either gender aged 1-60 months and an equal number of matching healthy controls. Malnutrition was categorised using the World Health Organisation criteria. Echocardiographic evaluation was done by expert cardiologists. Values for ejection fraction shortening, left ventricular mass, E/A wave ratio as well as mitral and tricuspid annular plane systolic excursions were noted. Data was analysed using SPSS 21. RESULTS: Of the 150 subjects, 75(50%) each were cases and controls. Age and gender were not significantly different between the groups (p>0.05). Left ventricular mass and left ventricular mass index with body surface area were significantly reduced in the cases compared to the controls, and the same was the case with left ventricular ejection fractional shortening (p<0.05). There was no significant difference between the groups in terms of E/A wave ratio as well as mitral and tricuspid annular plane systolic excursions (p>0.05). Among the cases, cardiac evaluation showed 26(34.6%) were kwashiorkor and 49(65.3%) were marasmic patients. CONCLUSIONS: Left ventricular parameters in malnourished children were found to be reduced. As such, the assessment of these parameters may appear to be a significant indicator for timely identification of cardiac malfunction in severe acute malnutrition cases.

Cefotaxime Loaded Polycaprolactone Based Polymeric Nanoparticles with Antifouling Properties for In-Vitro Drug Release Applications.

The objective of the present study was to achieve the successful encapsulation of a therapeutic agent to achieve antifouling functionality regarding biomedical applications. Considering nanotechnology, drug-loaded polycaprolactone (PCL)-based nanoparticles were prepared using a nano-precipitation technique by optimizing various process parameters. The resultant nano-formulations were investigated for in vitro drug release and antifouling applications. The prepared particles were characterized in terms of surface morphology and surface properties. Optimized blank and drug-loaded nanoparticles had an average size of 200 nm and 216 nm, respectively, with associated charges of -16.8 mV and -11.2 mV. Studies of the in vitro release of drug were carried out, which showed sustained release at two different pH, 5.5 and 7.4 Antifouling activity was observed against two bacterial strains, Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. The zone of inhibition of the optimized polymeric drug-loaded nanoparticle F-25 against both strains were compared with the pure drug. The gradual pH-responsive release of antibiotics from the biodegradable polymeric nanoparticles could significantly increase the efficiency and pharmacokinetics of the drug as compared to the pure drug. The acquired data significantly noted that the resultant nano-encapsulation of antifouling functionality could be a promising candidate for topical drug delivery systems and skin applications.
