Respiratory system compliance at the same PEEP level is similar in COVID and non-COVID ARDS

Background The comparison of respiratory system compliance (Crs) between COVID and non-COVID ARDS patients has been the object of debate, but few studies have evaluated it when considering applied positive end expiratory pressure (PEEP), which is one of the known determinants of Crs itself. The aim of this study was to compare Crs taking into account the applied PEEP. Methods Two cohorts of patients were created: those with COVID-ARDS and those with non-COVID ARDS. In the whole sample the association between Crs and type of ARDS at different PEEP levels was adjusted for anthropometric and clinical variables. As secondary analyses, patients were matched for predicted functional residual capacity and the same association was assessed. Moreover, the association between Crs and type of ARDS was reassessed at predefined PEEP level of 0, 5, 10, and 15 cmH2O with a propensity score-weighted linear model. Results 367 patients were included in the study, 276 patients with COVID-ARDS and 91 with non-COVID ARDS. The association between Crs and type of ARDS was not significant in both the complete cohorts (p = 0.17) and in the matched cohorts (p = 0.92). This was true also for the propensity score weighted association at PEEP 5, 10 and 15 cmH2O, while it was statistically significant at PEEP 0 (with a median difference of 3 ml/cmH2O, which in our opinion is not clinically significant). Conclusions The compliance of the respiratory system is similar between COVID ARDS and non-COVID ARDS when calculated at the same PEEP level and while taking into account patients’ anthropometric characteristics.

Comparison of Distance and Angular Analysis for Measurement of Hamstring Flexibility in Preschoolers

The study aimed to (1) investigate the reliability and usefulness of a proposed angular analysis during a modified sit-and-reach (MSR) test, and (2) compare the proposed MSR angular analysis and the commonly used MSR distance to verify the influence of the anthropometric characteristics in preschoolers. 194 preschoolers participated in the study. Before testing, the anthropometric characteristics were collected. Each participant performed the MSR test twice. The MSR distance score was obtained from the starting point to the reaching point, while the MSR angle score was calculated according to the approximate hip flexion angle. Both the relative and absolute reliability were good for the angular analysis during an MSR test in preschoolers (ICC ranging from 0.82 to 0.91, CV% ranging from 8.21 to 9.40). The angular analysis demonstrated good usefulness, with a lower typical error than the smallest worthwhile change in 3- and 5-year-old groups. The MSR angle scores could eliminate the concern of the influence of anthropometric characteristics, while MSR distance and anthropometric characteristics (i.e., sitting height and arm length) were found to be weakly correlated. In conclusion, the angular analysis when performing the MSR test is reliable and appears to eliminate the concern regarding the limb length bias.

Effects of diet on obesity-related anthropometric characteristics in adults: a protocol for an umbrella review of meta-analyses of randomised controlled trials

IntroductionThere have been many meta-analyses of randomised controlled trials on the influence of different diets on obesity-related anthropometric characteristics in adults. However, whether diet interventions can effectively decrease obesity-related anthropometric characteristics remains unclear. The objective of this study is to summarise and synthesise the evidence on the effects of diet on obesity-related anthropometric characteristics in adults by an umbrella review of meta-analyses of randomised controlled trials.Methods and analysisWe will first retrieve English articles only published before 15 December 2021 by searching PubMed, Embase and Web of Science. Only articles that are meta-analyses of randomised controlled trials will be included. Three researchers will independently screen the titles and abstracts of retrieved articles and check the data extracted from each eligible meta-analysis. In each meta-analysis, we will consider calculating the effect size of the mean difference of the effect of each diet on obesity-related anthropometric characteristics in adults using a random-effect model or a fixed-effect model according to heterogeneity. Study heterogeneity (Cochrane’s Q and I2 statistics) and small-study effects (Egger’s test or Begg’s test) will be considered. Evidence of each effect size will be graded according to the NutriGrade scoring system. We will use AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews V.2) to assess the methodological quality of each meta-analysis.Ethics and disseminationThis umbrella review will provide information on the effects of different diets on obesity-related anthropometric characteristics in adults. Ethical approval is not necessary for this study. We will publish the completed umbrella review and related data online.PROSPERO registration numberCRD42021232826.

Influence of Special Training Programs in Bodybuilding on Reducing Athletes’ Injuries

The purpose of the study was a comparative analysis of training programs in bodybuilding and an assessment of their influence on the frequency of traumatization of the musculoskeletal system of athletes. Materials and methods. Theoretical analysis of scientific and methodological literature was conducted. For a practical assessment of the primary data on the types of injuries, a survey of medical staff was conducted. We analyzed 54 journals with records of athletes' appeals to medical personnel. Mathematical processing of research results was carried out using the software packages IBM SPSS Statistics 2.0. The study, which was conducted during 4 months – from March to the end of June 2021, involved 60 bodybuilders aged 18-19 years old. Three research groups of 20 athletes each were formed. They were divided according to age, qualifications and anthropometric characteristics. The created groups did not have significant differences in these characteristics; the intergroup difference applied only to the proposed training programs. Results and discussion. In the course of the study, it was found that among the athletes of the control group who used the generally accepted program of training sessions with a certain sequence of using exercises of a basic and formative nature, the number of calls with certain pain sensations during four mesocycles of training decreased by 30.7% (p <0.05) compared to a similar period before the start of the study. At the same time, the results obtained show that among the athletes of the first main group, who used the combined program of training sessions in bodybuilding during the study, the controlled indicator of the number of calls decreased significantly – by 33.4% (p <0.05). Conclusion. In the process of studying the peculiarities of the influence of various programs of training sessions on the dynamics of morpho-functional indicators of the athletes’ organisms during four mesocycles of training sessions, a certain regularity was established regarding the ratio of the manifestations of types of injuries when performing strength exercises, depending on the sequence of their use. In the process of applying the methodical procedure "premature fatigue" on the dynamics of morphometric indicators of body weight of athletes it is shown that it is the third version of the program that contributes to a significant decrease in the number of calls (by 75%, p <0.05), compared with the results obtained over the period of the previous four mesocycles of intensive bodybuilding at the stage of specialized basic training of athletes

Validation of Two Instruments for the Correct Allocation of School Furniture in Secondary Schools to Prevent Back Pain

Background: Back pain is common in secondary school students. If we adjust the school furniture to the anthropometric characteristics of the pupils, we will improve their posture and reduce back pain. There is a high degree of mismatch between the furniture used by students and that which should be used. The objectives of this research are to discover the degree of mismatch and validate two instruments that allow a correct allocation of the furniture. Methods: The selected sample was 132 secondary students (14.08 ± 1.10 years). An anthropometer was used to determine the ideal height of the chair and table; data were taken from body segments. The recorded values were compared with those obtained by the two measurement instruments to be validated. Inter-measurer and intra-measurer reliability and validation were performed using t-tests and Pearson’s coefficient, respectively. Different analysis techniques were used: descriptive, one-way ANOVA, t-test, and effect size. The established level of significance was ρ < 0.05. Results: The mismatch between the anthropometric dimensions of the students and the existing furniture in the classrooms was 98.5 % for the chairs and 100 % for the tables. The correlational analysis of the instruments to be validated shows an r = 0.993 in the chair and r = 0.996 in the table. Conclusions: There is a high degree of mismatch between the furniture and the anthropometric characteristics of the students. The proposed furniture allocation instruments are adequate.

Association between grip strength and anthropometric characteristics in the community-dwelling elderly population in Taiwan

Background Sarcopenia and muscle weakness in elderly are contributed burden of public health and impact on quality of life. Weak grip strength was key role in diagnosis of sarcopenia and reported increased mortality, function declined in elderly. This study evaluated the association between GS and each common anthropometric characteristic in community-dwelling elderly. Design and method From 2017 to 2019, we conducted a community-based health survey among the elderly in Chiayi county, Taiwan. Participants were 65 years old or older, and total of 3,739 elderly subjects (1,600 males and 2,139 females) with a mean age of 76 years (range 65–85 years old) were recruited. General demographic data and lifestyle patterns were measured using a standard questionnaire. Anthropometric characteristics such as body height, body weight, body mass index (BMI), body waist and hip circumference, and body fat were measured by standard methods. GS was measured using a digital dynamometers (TKK5101) method. Results The mean GS was 32.8 ± 7.1 kg for males and 21.6 ± 4.8 kg for females (p < 0.001). For both sexes, elderly subjects with the same body weight but smaller body waist circumference had greater GS. The subjects with the same body waist size but heavier weight had greater GS. Furthermore, after adjusting for age, lifestyles, disease status, and potential anthropometric variable, multivariate regression analyses indicated that BMI was positively associated with GS (for males, beta = 0.310 and for females beta = 0.143, both p < 0.001) and body waist was negatively associated with GS (for males, beta = −0.108, p < 0.001; for females, beta = −0.030, p = 0.061). Conclusions This study suggested that old adults with higher waist circumstance had weaker GS. Waist circumstance was negatively associated with GS, body weight was positively associated with GS in contrast. It may implies that central obesity was more important than overweight for GS in elderly.

Physical Status of Primary School Children with Intellectual Disability Living in the City of Krasnoyarsk

Parameters of physical development are known to be informative indicators of health status and adaptation processes, as well as markers of social, hygienic and environmental well-being both in healthy children and those with various pathological conditions. The purpose of this article was to study the characteristics of the physical status of children with intellectual disabilities. Materials and methods. We examined 168 children of primary school age (7–11 years) studying in secondary schools of Krasnoyarsk. The subjects were divided into two groups: the first group included 54 children with intellectual disability (F70, F71 according to ICD-10), the second group included 114 children without intellectual disability. Anthropometric characteristics and level of physical development were studied taking into account regional centile tables. The harmony of physical development was assessed using the Quetelet index. Results. The physical development of children with intellectual disability is characterized by a lag in anthropometric characteristics compared with intellectually healthy children: body length was 133.0 and 137.3 cm (p = 0.048), head circumference 51.0 and 52.5 cm (p = 0.002) respectively. The first group also had a statistically significantly lower percentage of children with harmonious physical development (37 %, p = 0.045) against the background of pronounced disharmony (underweight in 31.5 %, excess body weight in 31.5 % of children) compared to their healthy peers (harmonious development in 55 %, underweight in 16 %, overweight in 29 % of children). Further research into the constitution of children with intellectual disability can form the basis for the development of corrective measures, taking into account the specific typological characteristics of children in this group.
