Growth, Nutrition and Economy : Proceedings of the 27th Aschauer Soiree, held at Krobielowice, Poland, November 16th 2019

Twenty-three scientists met at Krobielowice, Poland to discuss the role of growth, nutrition and economy on body size. Contrasting prevailing concepts, re-analyses of studies in Indonesian and Guatemalan school children with high prevalence of stunting failed to provide evidence for an association between nutritional status and body height. Direct effects of parental education on growth that were not transmitted via nutrition were shown in Indian datasets using network analysis and novel statistical methods (St. Nicolas House Analysis) that translate correlation matrices into network graphs. Data on Polish children suggest significant impact of socioeconomic sensitivity on child growth, with no effect of maternal money satisfaction. Height and maturation tempo affect the position of a child among its peers. Correlations also exist between mood disorders and height. Secular changes in height and weight varied across decades independent of population size. Historic and recent Russian data showed that height of persons whose fathers performed manual work were on average four cm shorter than persons whose fathers were high-degree specialists. Body height, menarcheal age, and body proportions are sensitive to socioeconomic variables. Additional topics included delayed motherhood and its associations with newborn size; geographic and socioeconomic indicators related to low birth weight, prematurity and stillbirth rate; data on anthropometric history of Brazil, 1850-1950; the impact of central nervous system stimulants on the growth of children with attention-deficit/hyperactivity disorder; and pituitary development and growth hormone secretion. Final discussions debated on reverse causality interfering between social position, and adolescent growth and developmental tempo.Facultad de Ciencias Naturales y Muse

Physical status, growth tracking and growth factors of children born in 1990 (longitudinal auxological study of children from Vilnius city and Vilnius region)

Physical status of children born in 1990 in Vilnius city and region from birth up to the end of puberty, the variety of individual growth tracks, ethnic and socio-economic growth factors, the epochal changes in growth and growth patterns of the “generation of independence” were investigated. This study was one of the first to establish the variety of individual growth tracks from birth to the age of eighteen years. In this longitudinal study of children born in 1990 (the year Lithuania restored its independence) the personal health records’ analysis was used and its benefits and drawbacks were investigated. The age of children, the place of residence (urban or rural), the distance to the outpatient clinic and the ordinal number of a child in a family were associated with the regularity of visiting the outpatient clinic. Children's growth indices in personal health records were rather accurate and suitable for auxological analysis. The results of this study confirmed that children normally changed their growth tracks for height and body mass index during the growth process. These changes were associated with their age and sex. Retardation in growth of children was related to the political and socioeconomic changes in Lithuania after 1990. Nevertheless, this retardation was reversible. Ethnic and socioeconomic differences in physical status of both boys and girls were established. The main body size indices (height, weight and body mass index) of children remained almost unchanged during last two decades, that meant the acceleration process had stabilized. Though the tendency towards higher body mass index was observed at the end of puberty for children of both sexes, the prevalence of overweight and obesity in Lithuania remained low

Pilot cadaveric study of anatomical variations of the median nerve at the wrist in the Lithuanian population

Carpal tunnel syndrome (CTS) is known as one of the most common neurological disorders in the human body. Nowadays, the prevalence in the general population ranges between 1% and 5%. Due to its high prevalence and increasing incidence of carpal tunnel surgery, the anatomical variations of the median nerve at the wrist are important to know to avoid iatrogenic injury of the nerve. Purpose: The objective of this study was to evaluate the anatomical variation of the median nerve at the level of the wrist in the Lithuanian population with a focus on its thenar motor branch based on the classifications of Lanz. Material and methods: A cadaveric study was performed, and 30 wrists of 15 adult Lithuanian cadavers ranging from 70 to 89 years of age were dissected and examined. Eight female and seven male cadavers were included in the study. Any anatomical finding was documented, and the results were compared with the classification of Lanz as well as with the data found in the literature. Results: All hands showed different patterns in comparison to the standard anatomical variation Lanz type 0. The most common result was dedicated to Lanz group 4A. Nineteen out of 30 hands (63%, p<0.01) had an accessory branch proximal to the carpal tunnel, while one of these hands showed a third thenar motor branch. Five hands (16%) were dedicated to Lanz group 2 with an accessory branch distal to the carpal tunnel. One hand (3%) showed a variation close to Lanz group 2, but in this case, the thenar motor branch had its origin under the flexor retinaculum instead of proximal to it. Two hands each (6%) were classified by Lanz groups 1B and 3A. Additionally, one variation showed a pattern of a combination of Lanz types 3A and 3B. The bifid median nerve had a connecting branch in between which started distal to the flexor retinaculum. Two anatomical variations (6%) were not described by the classification of Lanz

"Nepriklausomybės kartos" vaikų augimo tendencijos: socialinių ir ekonominių veiksnių sąsajos su augimo rodikliais

Background. The aim of the study was to evaluate the physical status of children born in 1990 in Vilnius City and Region from birth up to the end of puberty, and to investigate the epochal changes and tendencies of their growth. Materials and methods. 1 535 personal health records of children born in 1990 in Vilnius City and Region were analyzed. The main growth indices (height and weight) were recorded from birth up to the age of 18 years. The prevalence of overweight and obesity in children was found using the cut-off points for body mass index recommended by the International Obesity Task Force (Cole et al., 2000). The results of the present study were compared with the results of Lithuanian growth studies, as well as with the growth standards of the World Health Organization (WHO). Results. The prevalence of overweight and obesity in children born in 1990 in Vilnius City and Region was low: 13.60% and 2.40% in the 18-year-old boys and 9.51% and 1.90% in the 18-year-old girls, respectively. The retardation of growth was observed during the first years of independence. The main growth indices have changed in girls more than in boys: both their height (from 166.5 ± 7.0 cm to 167.9 ± 6.2 cm, during the two past decades) and their BMI (from 20.37 ± 2.27 kg/m2 to 21.28 ± 3.33 kg/m2, over the past ten years) increased. Conclusions. Certain retardation in growth of the children born in 1990 was related with the great political, social and economic transition in Lithuania. However, the retardation process was reversible. The main indices of the physical status (height, weight and body mass index) of children did not change much during the two past decades (the acceleration had stabilized). The growth patterns of the “generation of independence” by the end of adolescence showed the tendency towards a higher body weight, though the prevalence of overweight and obesity remained low

Variations in facial nerve branches and anatomical landmarks for its trunk identification: a pilot cadaveric study in the Lithuanian population

Objective The purpose of this study was to evaluate facial nerve (FN) branching variations based on Davis and Kopuz classifications in the Lithuanian population and measure the shortest distance from the facial nerve trunk (FNT) to its anatomical landmarks. Methods Twenty-two hemifaces of 11 cadavers were dissected. The preauricular skin cut was made and extended behind the ear lobe and along the inferior border of the mandible. The skin with subcutaneous tissue and superficial fascia were separated and medially retracted, and the parotid gland was dissected anterogradely. The FNT and its furcation type and branching pattern were disclosed and noted based on Davis and Kopuz classifications. Further, the shortest distance from the FNT to the anatomical landmarks of the tragal pointer (TP), the angle of mandible (AM), and the tip of mastoid process (TMP) was measured. Results The prevalence of branching patterns did not differ significantly compared to Davis classification. Based on Kopuz, type IVA pattern was the most common in six cases (27%). Eighteen (82%) trunks split as bifurcations and two (9%) trifurcations, while two (9%) had separate double trunks. The shortest distance (mm) from the FNT to the TP is 9.30 ± 0.93, AM 36.45 ± 4.14, and TMP 12.52 ± 2.30. Conclusion The prevalence of FN variations in the Lithuanian population is similar to Davis classification. The AM and TMP are consistent superficial bony landmarks for trunk identification, while the distance from the TP highly varies among studies. Surgeons should be aware of double FNT during parotidectomy, which is described in Kopuz classification

Associations between depression, height and body mass index in adolescent and adult population of Penza city and oblast, Russia

The aim of this study was to investigate the possible associations between depression, height and body mass index (BMI) in the adolescent and adult population of Penza city and oblast, Russia. The study included 554 adults aged 16–89 years. The presence and severity of depression was evaluated using Beck’s Depression Inventory (BDI-II). The participants self-reported their height (cm) and weight (kg) and these were used to calculate their BMI (kg/m2). Significant correlations were obtained between depression and short stature in young men, depression and short stature in participants with normal BMI and depression and age in overweight participants. Young women aged 16–23 years, and older men aged 60–89 years, presented the highest and very similar depression scores with no statistically significant difference between them. Special attention should be paid in Russia to these groups due to their higher risk of depressive disorders
