Influence of increased body mass index on orthodontic tooth movement and related parameters in children and adolescents: A systematic review of longitudinal controlled clinical studies.

Background: Overweight and obesity have become a major public health concern in recent decades, particularly in patients with chronic health conditions like congenital heart disease (CHD). This systematic review elaborates on the prevalence and the longitudinal development of overweight and obesity in children and adults with CHD. Methods: A systematic literature search was conducted in PubMed, Cochrane, and Scopus from January 2010 to December 2020 on overweight and obesity prevalence in children and adults with CHD. Results: Of 30 included studies, 15 studies evaluated 5680 pediatric patients with CHD, 9 studies evaluated 6657 adults with CHD (ACHD) and 6 studies examined 9273 both pediatric patients and ACHD. Fifteen studies received the quality rating “good”, nine studies “fair”, and six studies “poor”. In children with CHD, overweight prevalence was between 9.5–31.5%, and obesity prevalence was between 9.5–26%; in ACHD, overweight prevalence was between 22–53%, and obesity was between 7–26%. The prevalence of overweight and obesity was thereby similar to the general population. Overweight and obesity have been shown to increase with age. Conclusion: The prevalence of overweight and obesity in children and adults with CHD is similar to the general population, demonstrating that the growing obesity pandemic is also affecting the CHD population.

Overweight and Obesity in Patients with Congenital Heart Disease: A Systematic Review

The aim of the study is to determine the impact of obesity in children with CHD which is severe enough to require invasive catheterisation.This is a retrospective study in a cardiac catheterisation laboratory of a large paediatric hospital. The material consisted of 378 children from 2 to 19 years old who underwent heart catheterisation in the years 2011-2019. Their anthropometric data were collected, and the body mass index was calculated. The BMI centile was then calculated according to the Centers for Diseases Control (CDC). They were classified as overweight (85-95th centile), obese (> 95th centile), normal weight (5th-85 centile), and underweight (< 5th centile).18.7% of children were underweight, 54.76% were normal weight, 11.64% were overweight, and 14.81% were obese. Overall, 26.45% of the children were overweight. Boys were more likely to have increased body weight than girls, but the difference was not statistically significant. The percentage of increased weight was similar in children with acyanotic CHD as well as heart disease from other causes. On the contrary, children with cyanotic heart disease were more likely to be younger and have a higher percentage of underweight children.The rates of obesity and overweight in children with CHD depend on the sex, age, and cardiopathy type. In addition, they agree with the findings that have been published in international series studies for children with CHD.

Heterologous vaccination regimens could contribute to broadening vaccination coverage. To date, there is little evidence on the effectiveness of a combination of adenoviral COVID-19 vaccines with a second dose of mRNA vaccines. This study aims to evaluate the antibody response to the SARS-CoV-2 spike protein 25 weeks after vaccination with mRNA-1273 after a first dose of ChAdOx1. A cross-sectional study was conducted collecting sociodemographic data, clinical characteristics, and serological data from among the general population. Antibody levels were expressed as binding antibody units (BAU) per mL (cutoff = 33.8 BAU/mL). Linear regression models were used to assess the relationship between the subjects’ characteristics and anti-SARS-CoV-2 antibody levels. A total of 229 participants were followed up after a median time of 173 days. The overall anti-SARS-CoV-2 IgG antibody titer was 729.0 BAU/mL. The multivariable analysis showed that the only factor associated with anti-SARS-CoV-2 IgG levels was the BMI (p = 0.007), with decreases within the healthy range weight and increases in under- or overweight people. Our results support the use of heterologous COVID-19 vaccination regimens, as they can guarantee a sustained immune antibody response. More studies are needed to understand the link between BMI and body composition and the immune response to COVID-19 vaccinations.

Τhe Burden of Obesity on Adult Survivors of Congenital Heart Disease, Past, and Future Directions

Background and aims Adults with congenital heart disease (ACHD) are at risk of overweight and obesity, two major health problems, though underweight can be a negative prognostic factor too. Awareness of the body mass index (BMI) in ACHD is very limited. The present study describes the use and prevalence of BMI in Italian symptomatic hospitalized ACHD patients in relation to complexity by Bethesda system classification, diagnosis, sex and age. Methods and results We classified 1388 ACHD patients, aged 18–69 years, on the basis of their BMI, and compared them to the Italian reference population. In our total ACHD population we found a significantly higher prevalence of underweight compared to the Italian reference population (6.34% vs 3.20%). ACHD women were more underweight than men. Underweight decreased with age. Overweight was significantly less frequent in the total ACHD population (26.73% compared to 31.70%) in the Italian reference population. Men were more likely to be overweight than women. In statistical terms obesity was similar in the Italian reference population (10.50%) and our ACHD population (9.58%). Both overweight and obesity increased with age. Results were comparable using a diagnostic anatomical-functional classification and the Bethesda system classification. Conclusions In our cohort of ACHD the prevalence of underweight was double that of the Italian reference population. The prevalence of overweight was lower, while obesity was similar. Since BMI does not account for differences in body fat distribution, a future aim will be to quantify the visceral component of the adipose tissue in ACHD patients and examine their body composition in order to reflect their risk of acquired cardiovascular disease better, and either to maintain or achieve an adequate visceral component.
