ABSTRACT

AIMS: L-carnitine plays a role related to cardiometabolic factors, but its effectiveness and safety in CVD are still unknown. We aim to assess the effect of L-carnitine supplementation on CVD risk factors. METHODS: A systematic literature search was conducted in PubMed, Web of Science, and Scopus until October 2022. The main outcomes were lipid profiles, anthropometric parameters, insulin resistance, serum glucose levels, leptin, blood pressure, and inflammatory markers. The pooled weighted mean difference (WMD) was calculated using a random-effects model. RESULTS: We included the 21 RCTs (n = 2900) with 21 effect sizes in this study. L-carnitine supplementation had a significant effect on TG (WMD = - 13.50 mg/dl, p = 0.039), LDL (WMD = - 12.66 mg/dl, p < 0.001), FBG (WMD = - 6.24 mg/dl, p = 0.001), HbA1c (WMD = -0.37%, p = 0.013) HOMA-IR (WMD = -0.72, p = 0.038 (, CRP (WMD = - 0.07 mg/dl, P = 0.037), TNF-α (WMD = - 1.39 pg/ml, p = 0.033), weight (WMD = - 1.58 kg, p = 0.001 (, BMI (WMD = - 0.28 kg/m2, p = 0.017(, BFP (WMD = - 1.83, p < 0.001) and leptin (WMD = - 2.21 ng/ml, p = 0.003 (in intervention, compared to the placebo group, in the pooled analysis. CONCLUSIONS: This meta-analysis demonstrated that administration of L-carnitine in diabetic and glucose intolerance patients can significantly reduce TG, LDL-C, FBG, HbA1c, HOMA-IR, CRP, TNF-α, weight, BMI, BFP, and leptin levels. PROSPERO registration code: CRD42022366992.

ABSTRACT

OBJECTIVE: With the increase in the preterm birth rate, the factors influencing mortality and morbidity in very-low-birth weight neonates have gained importance in recent years. The results of available studies on the influence of birth hour on the mortality and morbidity rates of preterm infants are contradictory. Moreover, no study on this topic has been conducted in our region. MATERIALS AND METHODS: This retrospective cohort study was conducted on 127 very-low-birth weight newborns based on birth hour. The newborns were divided into 2 groups, the first born during working hours (7:00 am to 11:59 pm) and the second born during after-hours care (12-6:59 am). Mortality and major diseases were compared using Statistical Package for the Social Sciences by Fisher's exact tests, Pearson's chi-squared test, and independent t-tests. The statistical significance level for all analyses was set at P < .05 and the CI at 95%. RESULTS: Based on the results of this study in terms of neonatal mortality and major morbidities such as intraventricular hemorrhage and the need for prolonged mechanical ventilation, no significant difference was found between the 2 groups, but the difference in appearance, pulse, grimace, activity, respiration (APGAR) score at the fifth minute was statistically significant and was lower at the working hours. CONCLUSION: The results of the study may be due to appropriate allocation of resources, assignment of tasks, and professionalism of care in our study area. Further study is needed to determine the differences in clinical care processes that cause these results.

ABSTRACT

In this research, purification of molybdenite concentrate (MoS2) using a nitric acid leaching process was employed for the improvement of molybdenum trioxide morphology during oxidative roasting in an air atmosphere. These experiments were performed using 19 trials designed with response surface methodology and three effective parameters being temperature, time, and acid molarity. It was found that the leaching process reduced the chalcopyrite content in the concentrate by more than 95%. The influence of chalcopyrite elimination and roasting temperature on the morphology and fiber growth of the MoO3 was also investigated by SEM images. Copper plays an important role in controlling the morphology of MoO3 and its decrease led to enhancing the length of quasi-rectangular microfibers from less than 30 µm for impure MoO3 up to several centimeters for purified MoO3.

ABSTRACT

OBJECTIVE: The objective of this randomized controlled trial was to compare the treatment failure of suspected early onset neonatal sepsis with either 3-day or 5-day course of empirical antibiotic therapy. METHODS: Infants with birth weight over 1500 g and/or gestational age over 34 weeks within 7 days postnatal age with clinical symptoms of neonatal sepsis received empirical antibiotics (Ampicillin + Amikacin) in two neonatal intensive care units. After 72 hours if the result of blood culture was negative and symptoms resolved they were randomly allocated to 3-day or 5-day groups. The main outcome was treatment failure which was defined as reappearance of symptoms of sepsis within two weeks after discontinuation of antibiotics. Infants with congenital anomalies, localized infections, asphyxia, those undergoing surgery or when serum C-reactive protein levels remained abnormal despite treatment, were not included. Randomization was accomplished with simple randomization procedure. FINDINGS: Sixty patients were randomized in a 1:1 ratio to either group. Baseline characteristics were similar between two groups. The follow-up period was 2 weeks with no lost to follow-up. One infant in 3-day group had treatment failure compared with no treatment failure in 5-day group (P=0.5). No serious harm was observed due to our empirical antibiotic regimen. CONCLUSION: The results of this study indicated no evidence that treatment failure differs between 3-day and 5-day course antibiotic therapy for suspected early onset uncomplicated neonatal sepsis in late preterm and term newborns.
