Spherical harmonics to quantify cranial asymmetry in deformational plagiocephaly

Cranial deformation and deformational plagiocephaly (DP) in particular affect an important percentage of infants. The assessment and diagnosis of the deformation are commonly carried by manual measurements that provide low interuser accuracy. Another approach is the use of three-dimensional (3D) models. Nevertheless, in most cases, deformation measurements are carried out manually on the 3D model. It is necessary to develop methodologies for the detection of DP that are automatic, accurate and take profit on the high quantity of information of the 3D models. Spherical harmonics are proposed as a new methodology to identify DP from head 3D models. The ideal fitted ellipsoid for each head is computed and the orthogonal distances between head and ellipsoid are obtained. Finally, the distances are modelled using spherical harmonics. Spherical harmonic coefficients of degree 2 and order − 2 are identified as the correct ones to represent the asymmetry characteristic of DP. The obtained coefficient is compared to other anthropometric deformation indexes, such as Asymmetry Index, Oblique Cranial Length Ratio, Posterior Asymmetry Index and Anterior Asymmetry Index. The coefficient of degree 2 and order − 2 with a maximum degree of 4 is found to provide better results than the commonly computed anthropometric indexes in the detection of DP.

Relative children’s lipid accumulation with hypertension in Chinese children and adolescents

Background This study aimed to develop a novel indicator associated with hypertension in Chinese children and adolescents, the relative children’s lipid accumulation product (RCLAP). Methods A cross-sectional study was conducted in 2018. A total of 683 students aged 8–15 years were recruited via a stratified cluster sampling Methods. Anthropometric indexes (waist circumference (WC), Body mass index (BMI), Waist-height ratio (WHtR), logarithm children LAP (LnCLAP), RCLAP per height (RCLAP-H)) were standardized using a z-score method (standardized variables: SWC, SBMI, SWHtR, SLnCLAP, SRCLAP-H). A logistic regression model was performed to evaluate the association of the above indicators with the outcome of hypertension. Results The overall prevalence of hypertension was 5.7% (5.5% in boys, 6.0% in girls). SWC ≥ P75, SBMI ≥ P75, SWHtR ≥ P75, SlnCLAP ≥ P75 and SRCLAP-H ≥ P75 significantly increased risk of hypertension, with odds ratios (OR) of 2.21 (95% confidence interval (CI): 1.13, 4.30), 2.30 (1.18, 4.49), 2.64 (1.35, 5.14), 4.43 (2.28, 8.61), and 4.49 (2.31, 8.71), respectively. Conclusion RCLAP is a novel indicator associated with hypertension in Chinese children and adolescents, and it performs better than WC, BMI, WHtR and children LAP.

Tracking of risk factors for non-communicable diseases in young shooters, Ituiutaba, MG

The aim of this study was to detect early hypertension, diabetes and obesity, as well as their risk factors, in 105 young shooters from Tiro de Guerra 11-002 in the city of Ituiutaba-MG. This is a cross-sectional mixed study. A semi-structured questionnaire that contained questions related to the sociodemographic context, health status, lifestyle, eating habits, and psychosocial variables was applied. Blood pressure, anthropometric indexes, and lipid and glycemic profiles were measured. Descriptive and inferential statistics, including Pearson’s correlation test and Spearman’s coefficient, considering significative value (p < 0.05). The shooters had an average of 18.9 years old, most educated and brown. Anthropometric indices indicated a mainly eutrophic population, and normotensive and desirable lipid and glycemic profiles. However, overweight, high blood pressure, and self-declaration of family history for chronic diseases were identified. In addition, most shooters affirmed to ingest alcoholics beverages, to have insufficient time of physical activity, and to be aware of their levels of stress, pressure and anxiety and a few hours of sleep. Overall, the shooters showed good anthropometric and biochemical indicators of blood. Risk behavior, such as drinking alcoholic beverages and smoking, low level of physical activity and self-perception of stress, anxiety and pressure were also noted.

Impact of Obesity, Visceral Adiposity and Metabolic Syndrome on Male Fertility

OBJECTIVE: The study aimed to assess the association between the separate anthropometric indexes including visceral adiposity and metabolic syndrome on male fertility. STUDY DESIGN: In a cross-sectional study, the visceral and subcutaneous fat thickness of 162 participants were measured by ultrasonography. Participants' body mass index, waist circumference, and waist/hip ratio were determined. Participants' biochemical metabolic parameters and reproductive hormones were measured and semen parameters were recorded. Participants were divided into groups according to body mass index and different percentiles of the visceral fat thickness. Differences between groups were investigated by One-way ANOVA, Kruskal-Wallis H, and Pearson Chi-Square test. The relationship between anthropometric measurements and sperm parameters was evaluated by Pearson and Spearman’s rank correlation test. The effect of anthropometric indexes on sperm parameters was evaluated using multivariate regression analysis. RESULTS: It was seen that only total testosterone of sex hormones decreased significantly in the obesity group (p=0.003). There was a significant and reverse association between visceral fat thickness with sperm morphology (rho=–0.2, p=0.01). There was no significant correlation between semen parameters and other anthropometric measurements. In multiple regression analysis, the effect of anthropometric measurements, including visceral fat thickness, on semen parameters was not found, but only smoking was found to be a factor affecting sperm concentration, progressive motility, and morphology (p=0.03, p=0.03, and p=0.01). CONCLUSION: In this study, it was shown that increased obesity was associated with low testosterone levels and increased visceral fat was associated with abnormal sperm morphology. More extensive studies are required on this subject.

Histological chorioamnionitis is associated with an increased risk of wheezing in preterm children less than 34 gestational weeks

Background Chorioamnionitis is associated with various neonatal short- and long-term morbidities. The effect of chorioamnionitis on premature children’s outcomes remains controversial. The aim of this study is to investigate the relationship between histological chorioamnionitis (HCA) and physiological development, wheezing, and atopic diseases in preterm children. Methods Singleton, preterm children (< 34 weeks), whose mother underwent pathological placental examinations, were retrospectively enrolled and the outcomes were assessed at 24–40 months during follow-up. Wheezing and atopic diseases including eczema, food allergies, and allergic rhinitis were screened by a questionnaire along with medical diagnosis. Anthropometric indexes and blood pressure were measured. Cognitive and behavioural developments were assessed by the Gesell Development and Diagnosis Scale. Blood IgE and routine examination were analyzed with venous blood and serum metabolomic profiling was assessed via liquid chromatography-mass spectrometry (LC-MS). A multivariate logistic regression model was used to estimate the association between HCA and the current outcomes. Results Among the 115 enrolled children, 47 were exposed to HCA. The incidence of wheezing was significantly higher in children exposed to HCA, as 38.30% of children who were exposed to HCA and 16.18% of children who were not had been diagnosed with wheezing. After adjusting for related confounders in the multivariate logistic regression model, there remained a 2.72-fold increased risk of wheezing in children with HCA (adjusted odds ratio, aOR, 2.72; 95% confidence interval, 1.02–7.23). Moreover, 163 differential metabolites, such as butanoic acid, annotemoyin 1 and charine, were identified in the HCA exposed children’s serum. Enrichment analysis revealed that these compounds participated in diverse key metabolomic pathways relating to physical and neuro- developments, including glycerophospholipid, alpha-linolenic acid and choline metabolisms. There were no significant differences in atopic diseases, serum IgE, eosinophils’ level, anthropometric indexes, blood pressure, or cognitive or behavioural developments between the two groups. Conclusion HCA exposure is associated with an increased risk of wheezing in preterm children less than 34 gestational weeks.

Can Nutrition Education Improve the Nutrition Behavior and Anthropometric Indexes among Patients with Hypertension based on the Health Promotion Model?

Background: Following the rapid urbanization, unhealthy diet, enhanced life expectancy, and sedentary lifestyle has led to an increase in the prevalence of CVD and its risk factors, such as hypertension. Self-care is introduced as “behaviors directed toward oneself or the environment to formulate one’s functioning in the interest of one’s life, and well-being. Can nutrition education improve the nutrition behavior and anthropometric indexes among patients with hypertension based on the Health Promotion Model?Methods: A quasi-experimental and single-blind study was conducted on patients with hypertension attended to the Health Houses of Gorgan city of Iran between June 2018 and February 2019. To collect information, 68 patients in the control and 68 ones in the intervention arm were investigated. Data were collected by distributing self-administered questionnaires about HPM constructs, and testing 3-day diet record. Education was just conducted in the intervention arm including six sessions during three weeks, and in final, measurement was run two and six months after intervention. Results: There was no difference between the two groups about constructs of the HPM, anthropometric indexes, systolic and diastolic blood pressure and nutritional behavior before education, while after education all variables were significantly changed in two and six months’ follow-ups. Conclusion: HPM-based education might be likely useful to improve nutritional behaviors in patients with hypertension and it can also be applied in the health system of Golestan Province.
