Testing the speed-strength abilities in children and adolescents is a valuable tool of moni­toring the development of the most important physical qualities in sports. This test enables adjusting physical training to sensitive periods, identifying the degree of inherited sports talent, as well as a predisposition to the type of sport or sports discipline. Aim. The purpose of the work was to determine the average group results of Wingate test in children and adolescents and to identify the age-related dynamics of speed-strength abilities. Materials and methods. The study was conducted according to the standard Wingate protocol for a cycle ergometer. The obtained data on peak power (PP) and time to peak (tpp) of 370 athletes aged from 7 to 16 years were analyzed. Results. The results showed that no gender and age difference in PP was registered in children from 9 to 11 years (PP/kg – 8.42 ± 1.56 W/kg). The annual increase in PP/kg in boys was as follows: 11–12 years old – 7.53%, 12–13 years old – 17.7%, 13–14 years old – 10.34%. Relative PP in 14 year-old male athletes was 11.74 ± 2.15 W/kg, in 15 – 11.76 ± 1.56 W/kg and 16 year-olds – 12.2 ± 1.39 W/kg, with no significant difference. Relative PP in 14 and 15 year-old females (9.66 ± 2.12 W/kg and 9.88 ± 1.37 W/kg, respectively) was significantly lower than in males. Along with this no significant difference of PP/kg between 16 year-old males and females was established. Conclusion. The article proposes the criteria for evaluating speed-strength in athletes from 9 to 16 years based on the results of Wingate testing.

Eight minimally dressed pre- and early pubescent boys (age 11–12 yr) and 11 young adult men (age 19–34 yr) rested for 20 min and exercised on a cycle ergometer for 40 min at approximately 30% of their maximum oxygen consumption (VO2max) at 5 degrees C. To quantify the added increase in metabolic rate because of cold, a separate test was carried out at 21 degrees C at rest and at equal work rates as in the cold. Both groups were similar in subcutaneous fat thickness and VO2max per kilogram body weight. Rectal temperature increased slightly during the exposure to the cold, but no significant difference was observed between the boys and men. In the cold, the boys had lower skin temperatures than the adults in their extremities but not in the trunk. The boys increased their metabolic rates in the cold more than did the men. As a result, the boys maintained their core temperature as effectively as the adults. Similar age-related differences in thermoregulatory responses to cold were observed when two boys and two men with equal body sizes were compared. Our results suggest that there may be maturation-related differences in thermoregulation in the cold between children and adults.

Cortical Asymmetry

The aim of the present paper is to show how the variation of the EEG frontal cortical asymmetry is related to the general appreciation perceived during the observation of TV advertisements, in particular considering the influence of the gender and age on it. In particular, we investigated the influence of the gender on the perception of a car advertisement (Experiment1) and the influence of the factor age on a chewing gum commercial (Experiment2). Experiment1results showed statistically significant higher approach values for the men group throughout the commercial. Results from Experiment2showed significant lower values by older adults for the spot, containing scenes not very enjoyed by them. In both studies, there was no statistical significant difference in the scene relative to the product offering between the experimental populations, suggesting the absence in our study of a bias towards the specific product in the evaluated populations. These evidences state the importance of the creativity in advertising, in order to attract the target population.

In the length of time, a wide variety of drug combinations emerged in the management of post-transplantation therapy in order to improve the survival of the recipient and graft. However, the efficacy and safety of the applied combinations regarding the rejection and other complications are continuing to be the subject of research. In our study, our aim is to compare the effects of various combinations, namely cyclosporine with mycophenolate mofetil/mofetil mycophenolic acid with prednisolone and tacrolimus with mycophenolate mofetil/mofetil mycophenolic acid with prednisolone in a length of time. Methods. A total of 204 patients included into the study who received post-renal transplantation treatment in Scientific-Research Institute of Heart Surgery and Organs Transplantation and followed-up over a 10-year period. The estimated survival probabilities in the study were determined by the Kaplan-Meier method; whereas intragroup comparisons were evaluated by Log-rang, Breslow, and Tarone-Ware tests. Complications occurred in patients with combinations were analyzed by Chi-square and its alternatives. Hazard risk factors were tested by Cox regression analysis. Results. Of these 204 patients, 36 received Cyclosporin combination (CCG) and 168 Tacrolimus combination (TCG). The estimated life expectancy of the patients of TCG was significantly longer than the CCG ones. Furthermore, gender and age did not have a significant effect on survival depending on time, however, gender and age-related hazard factor showed a significant difference in the groups. It was determined that chronic rejection was significantly different in patients who used tacrolimus combinations, the difference was close to the significant value in acute rejection analysis. Other adverse events, namely, infection, tumour and organ damage were statistically less common in the patient group treated with tacrolimus combinations. Conclusion. In general, TCG showed better results in contrast to CCG.

ABSTRACTBackgroundIodine is an essential micronutrient for intellectual development in children. Information on iodine intakes based on 24-h urinary iodine excretion (UIE) is scant, because iodine status is only assessed by the measurement of urinary iodine concentration (UIC) in spot urine samples.ObjectivesThe aim of our study was to evaluate the iodine intake of school-age children and adolescents, using UIE measurement in 24-h urine collections.MethodsThe study population included 1270 healthy subjects (677 boys, 593 girls) aged 6–18 y (mean age ± SD: 10.3 ± 2.9) from 10 Italian regions. Daily iodine intake was estimated as UIE/0.92, based on the notion that $\sim$92% of the dietary iodine intake is absorbed. The adequacy of intakes was assessed according to the Dietary Reference Values for iodine of the European Food Safety Authority (EFSA). Body mass index (BMI) and UIC were also measured for each subject.ResultsBased on the scientific opinion of EFSA, 600 of 1270 subjects (47.2%) had a lower than adequate iodine intake, with a higher prevalence among girls (54.6%) compared with boys (40.2%) (P < 0.001). Although UIE and 24-h urinary volumes increased with age (P < 0.001), a progressive decrease in the percentage of subjects with iodine excretion <100 µg/24 h (P < 0.001) was observed, without any significant difference in the percentage of subjects with UIC <100 µg/L. No significant association was detected between BMI z-score and UIE (P = 0.603) or UIC (P = 0.869).ConclusionsA sizable proportion of our population, especially girls, appeared to be at risk of iodine inadequacy. The simple measurement of UIC could lead to underestimation of the occurrence of iodine deficiency in younger children, because of the age-related smaller urine volumes producing spuriously higher iodine concentrations.

Purpose. To report the occurrence of endophthalmitis and other complications after intravitreal injections (IVIs) in the Arc Sterile setting. Methods. A retrospective study that enrolled all patients who underwent IVIs between November 2017 and March 2019, collecting data about the patient’s gender and age, type of injected drug, diagnosis, other ocular pathologies, physician and possible occurrence of endophthalmitis, or other complications. Results. Ten thousand and eighty-three IVIs were performed during the study period, involving 2014 eyes of 1,670 patients with an average age of 71.37 ± 11.63 years. The injected drugs included ranibizumab (54.6%), aflibercept (38.0%), dexamethasone (6.7%), pegaptanib (0.3%), bevacizumab (0.4%), and ocriplasmin (0.01%). The diagnosis included neovascular age-related macular degeneration (859), myopic choroidal neovascularization (154), diabetic macular edema (576), retinal vein occlusion (203), and miscellaneus diagnosis (222). No cases of endophthalmitis were recorded. One hundred and sixty-nine cases of ocular hypertension were detected, while the most frequent complication was subconjunctival hemorrhage, identified after 1,180 IVIs. The residents performed over 80% of IVIs, but there was no statistically significant difference in incidence of complications between the residents group and consultants group. Conclusions. Arc Sterile seems to be a safe setting in which IVIs can be carried out, regarding infective risk, and it is easy to set up compared to operation theatre and useful to improve intravitreal injections governance.

<p><strong>Objectives.</strong> The aim of this research was to detect the presence of depressive symptoms among the student population at a Faculty of Medicine, as well to determine the correlation between the socio-demographic characteristics and students’ lifestyle and depressive symptoms.</p><p><strong>Subjects and Methods. </strong>Of 800 students enrolled and asked to participate, 412 responded to the survey. The study included Students from all 6 years of studies. The degree of depressive symptoms was measured by a 21-item revised form of the Beck Depression Inventory (BDI). We built bivariate logistic regression models to study whether age, gender, housing accommodation, year of medical training, and school success status (Grade Point Average - GPA) were associated with depressive symptoms. The results are reported as odds ratios (OR) with 95% confidence intervals (CI).</p><p><strong>Results</strong>. The study revealed that almost one third of students reported BDI &gt;16 (30.1%). The present study did not find any association between BDI scores and study year or age difference, but we found that there was an association between housing accommodation and depressive symptoms. Students who lived with their parents had lower BDI scores than those who lived in a dormitory. The results of this study showed there is a negative correlation between physical activity and depressive symptoms in students, as well as that there is a positive correlation between depressive symptoms and substance abuse.  </p><p><strong>Conclusion</strong>. Overall, our study confirms that the factors associated with an increase in medical students’ depressive symptoms are housing accommodation, a lack of  physical activity and substance abuse. Regarding failing a year of study at the medical school, as well as gender and age differences, we did not find any significant difference between students with higher compared to those with lower depressive symptoms.</p>

Introduction: Normative data on handgrip strength (HGS) and body mass index (BMI) are scarce among adolescents in the Nigerian context. The aims of this study were to evaluate patterns of HGS in relation to gender and age in Nigerian adolescents and its correlation with BMI.Methods: This cross-sectional study involved 1966 participants (1275 males) and (691 females) aged 12–20 years in Northern Nigeria. Body mass and height were measured. HGS was assessed using a dynamometer.Results: The right HGS (RHGS) was significantly higher than the left HGS (LHGS) (t = 21.337, p < 0.05). There were significant age differences in the RHGS and the LHGS (p < 0.05); however, no significant difference occurs at 12–14 years. Males participants aged 16–20 years had significantly higher RHGS values than females of the same age (p < 0.0038). Conversely, males aged 15–20 years had significantly higher LHGS values than females of the same age (p < 0.0038). There was a significant interaction between gender and age for the RHGS (F = 72.2, p < 0.05) and the LHGS (F = 92.1, p < 0.05). There was a significant correlation between the BMI and RHGS (r = 0.480, p < 0.01) and the LHGS (r = 0.465, p < 0.01).Conclusion: There are gender and age difference in the HGS of Nigerian adolescents, with the dominance of the RHGS in both genders. HGS correlated with BMI. This normative data on HGS may serve as baseline data for future comparative studies assessing HGS among the adolescent population in Nigeria.

Background and Objectives: Clinicians are called to overcome age-related challenges in decision making during In Vitro Fertilization (IVF) treatment. The aim of this study was to investigate the possible impact of a single calendar year difference among patients aged 34, 35 and 36 on IVF outcomes. Materials and Methods: Medical records between 2008 and 2019 were analyzed retrospectively. The study group consisted of women diagnosed with tubal factor infertility. Sample size was divided in three categories at 34, 35 and 36 years of age. Embryo transfer including two blastocysts was performed for every patient. Comparisons were performed regarding hormonal profile, response to stimulation, quality of transferred embryos, positive hCG test and clinical pregnancy rate. Results: A total of 706 women were eligible to participate. Two-hundred and forty-eight women were 34, 226 were 35 while the remaining 232 were 36 years old. Regarding the hormonal profile, the number of accumulated oocytes and the quality of embryos transferred, no statistically significant difference was documented between the three age groups. Women aged 34 and 35 years old indicated a significantly increased positive hCG rate in comparison to women aged 36 years old (p-value = 0.009, p-value = 0.023, respectively). Women aged 34 and 35 years old presented with a higher clinical pregnancy rate in comparison to those aged 36 years old (p-value = 0.04, p-value = 0.05, respectively). Conclusion: A calendar year difference between patients undergoing IVF treatment at 34 or 35 years of age does not appear to exert any influence regarding outcome. When treatment involves patients above the age of 35, then a single calendar year may exert considerable impact on IVF outcome. This observation indicates that age 35 may serve as a valid cut-off point regarding IVF outcome.

Abstract: Assessing and discovering the major depression symptoms among men and women, even in the early stages of development, are key elements in the construction and standardization of psychometric instruments. This study aimed to evaluate the differences in the expression of depressive symptoms by gender and age group. The sample consisted of 1,697 students aged 8-17 years. The data collected through the Escala Baptista de Depressão infantojuvenil were submitted to item response theory analysis. Results showed that internalizing symptoms are more common in girls and externalizing symptoms in boys. It can be concluded that standards for boys and girls should differ, just like different standards are needed for children and adolescents.

Left ventricular function including regional wall motion (RWM) was evaluated by 99mTc first-pass and equilibrium gated blood pool ventriculography and glycohemoglobin (HbA1c) blood levels determined by a quantitative column technique in 25 young patients with insulin-dependent diabetes mellitus without clinical evidence of heart disease, and in healthy controls matched for age and sex. Phase analysis revealed abnormal RWM in 19 of 21 diabetic patients. The mean left ventricular global ejection fraction, the mean regional ejection fraction and the mean 1/3 filling fraction were lower and the time to peak ejection, the time to peak filling and the time to peak ejection /cardiac cycle were longer in diabetics than in controls. We found high HbA1c levels in all diabetics. There was no significant difference between patients with and without retinopathy and with and without peripheral neuropathy in terms of left ventricular function and HbA1c levels.
