Implications of Pharmacokinetic Potentials of Pioglitazone Enantiomers in Rat Plasma Mediated through Glucose Uptake Assay.

Pioglitazone, a PPAR-gamma activator used to diagnose hyperglycemia, was studied for its stereoselective deposition and active enantiomers in female albino Wistar rats. In accordance with USFDA recommendations, a bioanalytical technique was employed to assess the segregation of pioglitazone enantiomers in rat plasma with glimepiride as an internal standard. A Phenomenox i-Amylose-3 column (150 mm × 4.6 mm) of 5 µm was used for high-performance liquid chromatography (HPLC) with a mobile phase of 10 mM ammonium acetate buffer in Millipore water and acetonitrile in 60:40 (v/v) admixture with column temperature 35 °C, wavelength 265 nm, and flow rate 0.6 mL/min, respectively. Pioglitazone-S, Pioglitazone-R, and the internal standard had retention times of 3.1, 7.4, and 1.7 min, respectively. The study found that within-run and between-run precision ranged from 0.1606-0.9889% for Pioglitazone-R and from 0.2080-0.7919% for Pioglitazone-S, while the accuracy ranged from 99.86 to 100.36% for Pioglitazone-R and 99.84 to 99.94% for Pioglitazone-S. In addition, a non-radioactive glucose uptake assay was employed to examine the enantiomers in 3T3-L1 cell lines by flow cytometry. Significant differences were demonstrated in Cmax, AUClast (h*µg/mL), AUCINF obs (h*µg/mL), and AUC%Extrap obs (%) of Pioglitazone-R and S in female albino Wistar rats, suggesting enantioselectivity of pioglitazone.

Knowledge, Attitude, and Practice in Management of Childhood Fever Among Saudi Parents.

Fever is considered as a frequent symptom in childhood and is the cause of almost 65% to 70% of pediatric visits. Saudi Arabia has about 10% of child population (under 4 years of age), imposing a high burden of childhood illnesses including fever. A total of 1700 questionnaires were distributed to Saudi parents with children visiting pediatric clinic. Most of the participants were mothers (77.4%). A temperature of 38.0 °C was defined fever by 42% of participants. The majority of parents (80%) believed seizure is the consequence of untreated high fever. A total of 72.5% indicated that 40.7 to 43.20°C is the highest temperature that can be reached if untreated. There was a statistically significant relationship between mothers and fathers for overall knowledge, attitude, and practice scores. This study indicates that numerous misconceptions still persist regarding fever as more than 90% of parents demonstrated undue fear of consequent body damage from fever and also believed antibiotics can reduce high temperature.
