BackgroundVentilator-associated pneumonia (VAP) is a serious health care- associated infection, resulting in high morbidity and mortality. It also prolongs hospital stay and drives up hospital costs. Measures employed in preventing ventilator- associated pneumonia in developing countries are rarely reported. In this study we tried to assess the efficacy of our designed “VAP prevention bundle” in reducing VAP rate in our neonatal intensive care unit (NICU).MethodThis prospective before-and-after study was conducted at university hospital NICU, all neonates who had mechanical ventilation for ≥ 48 h were eligible. VAP rates were evaluated before (phase-I) and after (phase-II) full implementation of comprehensive preventive measures specifically designed by our infection control team.ResultsOf 143 mechanically ventilated neonates, 73 patients developed VAP (51 %) throughout the study period (2500 mechanical ventilation days). The rate of VAP was significantly reduced from 67.8 % (42/62) corresponding to 36.4 VAP episodes/1000 mechanical ventilation days (MV days) in phase-I to 38.2 % (31/81) corresponding to 23 VAP/1000 MV days (RR 0.565, 95 % confidence interval 0.408-0.782, p = 0.0006) after VAP prevention bundle implementation (phase-II). Parallel significant reduction in MV days/case were documented in post-intervention period (21.50 ± 7.6 days in phase-I versus 10.36 ± 5.2 days in phase-II, p = 0.000). There were a trend toward reduction in NICU length of stay (23.9 ± 10.3 versus 22.8 ± 9.6 days, p = 0.56) and overall mortality (25 % versus 17.3 %, p = 0.215) between the two phases but didn’t reach statistical significance. The commonest micro-organisms isolated throughout the study were gram-negative bacteria (63/66, 95.5 %) particularly Klebsilla pneumonia (55/66, 83.4 %).ConclusionImplementation of multifaceted infection control bundle resulted in reduction of VAP rate, length of stay in our NICU.

Dietary supplementation with magnesium (Mg) in addition to classical therapies for diabetes may help in prevention or delaying of diabetic complications.We aimed to evaluate the status of serum Mg in children with type 1 diabetes and assessing its relationship to glycemic control and lipid profile. Then evaluating the effect of oral Mg supplementation on glycemic control and lipid parameters.We included 71 children at Pediatric Endocrinology Outpatient Clinic, Zagazig University, Egypt with type 1 diabetes and assessed HBA1c, lipid profile, and serum Mg at the start of study. Patients with serum Mg level < 1.7 mg/dL were given 300 mg Mg oxide for 3 months. After that we reevaluated HBA1c, lipid profile, and serum Mg in all patients.The study included 71 patients with type 1 diabetes (32 males and 39 females); their mean age was 9.68 ± 3.99 years. The mean serum Mg level was 1.83 ± .27 mg/dL. Hypomagnesemia was detected in 28.2% study patients. Serum Mg was found to be positively correlated with high density lipoprotein, mean corpuscular volume and platelet count (P < 0.001), and negatively correlated with age, HbA1c, triglycerides, total cholesterol, low density lipoprotein, and duration of diabetes (P < 0.001). There was significant reduction in HBA1c in group given Mg supplementation. HBA1c was initially 10.11% ± 0.87%. After 3 months of oral Mg supplementation it is reduced to 7.88% ± 0.42% (P < 0.001). There was statistically significant difference in lipid parameters in hypomagnesemic diabetic patients before and after Mg supplementation with significant reduction in serum triglycerides, LDL, and total cholesterol following Mg supplementation with P < 0.001. Although HDL shows a significant increase after Mg supplementation in hypomagnesemic diabetic children with P < 0.001.Correction of hypomagnesemia in type 1 diabetic children with oral Mg supplements is associated with optimization of glycemic control and reduction of atherogenic lipid fraction as well as increase in protective lipid fraction.

BackgroundThe early imbalances of trace elements in type 1 diabetes (T1D) may cause disturbance of glucose metabolism and more oxidative stress that may enhance the development of insulin resistance and diabetic complications. We aim to evaluate the serum level of selenium (Se), zinc (Zn), magnesium (Mg), and copper (Cu), the degree of oxidative stress and evaluate their relations to glycemic control in children with T1D.MethodsA case–control study which included 100 diabetic children and 40 healthy children age, sex, and ethnicity-matched as a control group. The diabetic children were divided into poor and good controlled patients according to glycosylated hemoglobin (A1c %). Studied children underwent history taking, clinical examination and laboratory measurement of serum Se, Zn, Mg, and Cu levels, erythrocyte reduced glutathione (GSH) and peroxidase enzyme activity (GPx).ResultsSerum Se, Zn, Mg, Cu, erythrocyte GSH, and GPx were significantly lower in the diabetic group in comparison to the control group (P<0.05) and their levels were lower in poorly controlled patients compared to good controlled patients (P<0.05). The serum Se, Zn, Mg, erythrocyte GSH, and GPx showed a negative correlation with A1c %. The serum Se showed a positive correlation with erythrocyte GSH and GPx ([r=0.56, P<0.001], [r=0.78, P<0.001], respectively).ConclusionChildren with T1D, especially poorly controlled cases, had low serum Se, Zn, Mg, Cu, GSH, and GPx. Low serum Se in diabetic children may affect the erythrocyte GSH-GPx system.
