BackgroundMalnutrition among children population of less developed countries is a major health problem. Inadequate food intake and infectious diseases are combined to increase further the prevalence. Malnourishment brings to muscle cells loss with development of cardiac complications, like arrhythmias, cardiomyopathy and sudden death. In developed countries, malnutrition has generally a different etiology, like chronic diseases. The aim of our study was to investigate the correlation between malnutrition and left ventricular mass in an African children population.Methods313 children were studied, in the region of Antsiranana, Madagascar, with age ranging from 4 to 16 years old (mean 7,8 ± 3 years). A clinical and echocardiographic evaluation was performed with annotation of anthropometric and left ventricle parameters. Malnutrition was defined as a body mass index (BMI) value age- and sex-specific of 16, 17 and 18,5 at the age of 18, or under the 15th percentile. Left ventricle mass was indexed by height2.7 (LVMI).ResultsWe identified a very high prevalence of children malnutrition: 124 children, according to BMI values, and 100 children under the 15th percentile. LVMI values have shown to be increased in proportion to BMI percentiles ranging from 29,8 ± 10,8 g/m2.7 in the malnutrition group to 45 ± 15,1 g/m2.7 in >95th percentile group. LVMI values in children < 15th BMI percentile were significantly lower compared to normal nutritional status (29,8 ± 10,8 g/m2,7 vs. 32,9 ± 12,1 g/m2,7, p = 0.02). Also with BMI values evaluation, malnourished children showed statistically lower values of LVMI (29,3 ± 10,1 g/m2,7 vs. 33,6 ± 12,5 g/m2,7, p = 0.001).ConclusionIn African children population, the malnourishment status is correlated with cardiac muscle mass decrease, which appears to be reduced in proportion to the decrease in body size.
Laboratory-markers of the systemic inflammatory-response, such as neutrophil/lymphocyte-ratio (NLR) have been studied as prognostic factors in several tumors but in OC-patients their role is still controversial and no data about the possible correlation with the BRCA-status has been ever reported. We consecutively enrolled a series of 397 newly diagnosed high-grade serous-advanced OC-patients. All patients were tested for BRCA-mutational-status and blood-parameters have been collected 48 h before staging-surgery. A significant correlation of NLR with disease distribution (p < 0.005) was found and patients with NLR < 4 underwent primary-debulking-surgery more frequently (p-value 0.001), with a lower surgical-complexity-score (p-value 0.002). Regarding survival-data, patients with NLR < 4 had a significant 7-month increase in mPFS (26 vs 19 months, p = 0.009); focusing on the BRCA-status, among both BRCA-mutated and BRCA-wild type patients, those with lower NLR had a significantly prolonged mPFS compared to patients with NLR > 4 (BRCA-mutated: 35 vs 23 months, p = 0.03; BRCA-wt: 19 vs 16 months, p = 0.05). At multivariate-analysis, independent factors of prolonged PFS were BRCA mutational status, having received complete cytoreduction and NLR < 4. Also, the strongest predictors of longer OS were BRCA-mutational status, having received complete cytoreductive surgery, NLR < 4 and age. NLR is confirmed to be a prognostic marker in OC-patients and it seems unrelated with BRCA-mutational status.
The patterns and prevalence of early repolarization pattern (ER in paediatric populations from different ethnic backgrounds other than Caucasian have not been determined. Methods We analyzed ECGs of black children (ages xx-yy) who were prospectively recruited in the northwest Madagascar and compared them to age & sex matched Caucasian ethnicity individuals. ERP was defined by ≥0.1 mV J-point elevation in at least two contiguous inferior and/or lateral ECG leads. Results A total of 616 children were included. There was a trend toward a higher frequency of ERP in the Africans compared to the Caucasians (23.3% vs 17.1% respectively, p=0.053). The subtype (slurred versus notched) and location of ERP (lateral, inferior or infero-lateral) were significantly different in the two groups (p<0.001 and p=0.020, respectively). There was no significant difference in the number of high-risk ECG features of ERP (i.e. horizontal/descendent pattern, inferior or infero-lateral location or J-waves ≥2 mm) between Malagasy and Caucasian children. On the multivariate analysis, Malagasy ethnicity and faster heart rate were independent predictive factors of ERP (OR 3.57, 95%CI 2.04-6.25, p<0.001 and 0.98, 95%CI 0.962-0.987, p<0.001, respectively). Conclusions African children have an increased risk of ER compared to Caucasian counterparts. Future studies should clarify the clinical and prognostic significance of ERP in the pediatric population, and whether ethnicity has an impact on the outcomes.
