The aim of the study was to compare the state of psychophysiological functions of highly qualified handball players with different experience of sports training (special training). To determine the state of psychophysiological functions of athletes diagnostic complex "Diagnostics-1" was used (MV Makarenko, VS Lyzogub). In accordance with the purpose of the work, we studied the properties of the nervous system (functional mobility and strength of nervous processes), the efficiency of sensorimotor activity and the dynamics of nervous processes in feedback, the latency of complex response reactions of choice, the accuracy of response to a moving object. Higher psychophysiological status in terms of the strength of nervous processes (both in the feedback mode and during long-term sensorimotor loads in the mode of imposed rhythm) was demonstrated by athletes of the older age group with more experience of sports training. Athletes of older and younger age groups did not differ in the level of functional mobility of nervous processes and accuracy of reaction to a moving object. Therefore, we can assume that athletes with less experience of sports training in the state of these psychophysiological functions have reached the level of athletes of the older age group, ie the level of maximum realization of individual capabilities. The identified differences in the individual-typological properties of the higher parts of the central nervous system in female handball players with different sports experience can have prognostic value and be used to optimize sports improvement in this sport.

The aim of the study was to determine the relationship between dynamic muscular endurance of the hand (according to the tapping test) with the state of psychophysiological functions of qualified female handball players at different stages of sports training. Diagnostic complex "Diagnostics-1" (MV Makarenko, VS Lyzogub) was used to determine the state of psychophysiological functions of athletes, the maximum rate ofmovement of the brush. Dynamic muscular endurance of the right and left brushs, properties of the nervous system (functional mobility and strength of nervous processes), the effectiveness of sensorimotor activity and the dynamics of nervous processes, the latency period of a complex reaction of choice, the accuracy of the reaction to a moving object were studied in accordance with the purpose of the study. Dynamic muscular endurance of subdominant hand was significantly higher in older female athletes. There is a tendency to increase the dynamic muscular endurance of the dominant hand in older female athletes. The asymmetry according to the indicators of the tapping test between the right and left hand was lower in the older age group than in the younger age group. In general, the results indicate a higher level of dynamic muscular endurance of both arms in older female athletes, who are more adapted to long-term specific physical activity. That is, the improvement of special training in handball leads to the development of dynamic muscular endurance. This is confirmed by the results of the correlation analysis of the obtained data: dynamic muscular endurance of the subdominant arm was associated with the experience of sports training. The maximum rate of movement of the brush of both hands in the surveyed female athletes was associated with the strength of nervous processes and the accuracy of the reaction to a moving object. The dynamic muscular endurance of the dominant hand' brush was associated with the functional mobility of nervous processes.

The Central Nervous System

Introduction. In modern sports, a high level of physical performance of the athlete is due to the functional properties and condition of all body systems. Of particular importance is the assessment of the functional state of the central nervous system. At the same time, the potential risk of injuries increases with each passing year, so one of the main tasks of sports physicians, psychologists, physiologists, especially in high-achievement sports, is to reduce injuries in sports. The aim of the study was to compare the state of psychophysiological functions of highly qualified athletes who specialize in sports with varying degrees of extremeness (snowboarding, downhill skiing, cross-country skiing). Material and methods. To determine the state of psychophysiological functions of athletes used diagnostic complex "Diagnostics-1" (MV Makarenko, VS Lyzogub). The group of respondents included qualified athletes engaged in skiing, characterized by the predominance of dynamic speed and a high probability of injury. These sports make special demands primarily on the central nervous system of athletes. In accordance with the purpose of the work, we studied the latent periods of simple visual-motor reaction, simple and complex reaction of choice, the efficiency of sensorimotor activity and the dynamics of nervous processes in the feedback mode, the accuracy of the reaction to a moving object and the ratio of reactions of advance and delay, dynamic muscular endurance of the right and left hands (according to the tapping test), as well as the basic properties of the nervous system namely the functional mobility of nervous processes and the strength of nervous processes. Results. Athletes with a higher degree of extreme sports and risk of injury (snowboarders and skiers) showed a higher psychophysiological status in terms of strength of nervous processes and indicators of reaction to a moving object, a higher level of dynamic muscular endurance in terms of tapping test. Conclusions. The identified differences in the state of psychophysiological functions in athletes with varying degrees of extreme sports activities and the level of risk of injury can have prognostic value and be used to optimize sports improvement in these sports.

ObjectiveWe previously reported increasing free T3 (FT3) to free T4 (FT4) ratios as thyroid-stimulating hormone (TSH) increases within the normal range in children. It is not known if this phenomenon is age-related among humans, as previously reported in rats. This study examines the relationships between TSH and FT3/FT4 ratios in different ages.DesignRetrospective examination of thyroid tests from patients without thyroid disease from community clinics.MethodsFree T3, free T4, and TSH levels from 527 564 sera collected from patients aged 1 year or greater were studied. Exclusion criteria were the following: missing data, TSH greater than 7.5mIU/L, and medications that may interfere with thyroid hormone activity. A total of 27 940 samples remaining after exclusion were stratified by age. Samples with available anthropometric data were additionally stratified for body mass index (BMI). Correlations of TSH to FT4, FT3, and FT3/FT4 ratios by age group were examined.ResultsUp to age 40, for each increasing TSH quartile, FT3 and the FT3/FT4 ratio increased and FT4 decreased significantly (for both FT3, FT4 and FT3/FT4 ratio,P<0.05 for every TSH quartile when compared with the 1st quartile, except FT3 in the 30–40 age group). In older age groups, increasing TSH was not associated with increased FT3/FT4 ratio.ConclusionAs TSH levels increase, FT3/FT4 ratios increase until age 40, but this differential increase does not occur in older age groups. This may reflect a decrease in thyroxine (T4) to triiodothyronine (T3) conversion with age, which may be part of the aging process.

Interpretation Of Change

This investigation is not concerned with the clinical indications or results of prefrontal leucotomy, but attempts to re-examine changes following the operation, especially in regard to the impairment of some of the manifestations of the highest integrative psychophysiological functions of the central nervous system that may bring about such alterations. Amongst these we were primarily interested in cognitive changes, but the interpretation of apparent cognitive changes led to the consideration of orectic alterations as well. Such changes have so far been impossible to localize exactly, but are considered to be partly related to the phylogenetically more recent parts of the cerebral cortex. Masserman (1946) compared the mechanism of shock treatment and leucotomy with the effects of alcohol and states that “its main actions are those of a cortical depressant,” as manifested by impairment of finer perceptions and discriminations and a “constriction of the integrative field.” He believes that shock therapies and leucotomy partly produce their results by temporary or permanent decorticating effects, “rendering the individual no longer capable of fine spun fantasies or elaborate delusions.” These decorticating effects can be assumed to be reflected in cognitive, conative and emotional alterations following the operation. The interpretation of change following leucotomy presents many difficulties, one of them being that only dysfunction can be related to structural damage of the frontal lobe and not function. Another is that psychotics or severe neurotics operated upon usually do not have a sufficiently intact pre-operative personality to draw conclusions about the normal functions.

Abstract It is estimated that the prevalence of adrenal incidentaloma increases with age: ~3% of those aged 50 years, rising to 10% in those &gt;70 years (1). Given the aging population together with increased utilisation of cross-sectional imaging in the UK (eg CT urogram, MR angiogram), we explored the proportion of patients with adrenal incidentaloma by age based on current imaging trends. Furthermore, there is no information currently available on the relationship between age and pattern of endocrine referrals. We extracted data for all CT and MRI scans from Jan 2018-Oct 2019 and used key phrases in radiology reports (eg adrenal adenoma/lesion/mass/nodule/incidentaloma, incidental adrenal, indeterminate adrenal) to identify potential lesions. We also extracted data on patient age and referral patterns as identified by a logged referral or an attendance (new or follow-up) to endocrine clinic 3 months post index scan, stratified by 10 year age groups. Where possible, we excluded false hits (eg no adrenal lesion). Preliminary data showed that, of the 2604 potential lesions identified by CT and MRI scans, 78.7% were on patients aged over 60 years. The numbers of identified lesions gradually increased with age to a peak in the 71-80 year age group after which these declined. Whilst patients younger that 60 years had fewer potential lesions identified, they were more likely to be referred to endocrine services (73 out of 55 patients; 13.2%) than those in the older age group (168 out of 2049; 8.2%; p&lt;0.001). Indeed there was a statistically significant trend towards decreasing referral with age group (Chi-squared test for trend; p&lt;0.001). In conclusion, patients over 60 years have a higher number of potential adrenal incidentalomas. However, this group is less likely to be referred for endocrine evaluation. This is particularly concerning given the large number of scans requested and the higher prevalence of incidentalomas in this age group. This study represents preparatory work on innovations to enhance case detection, particularly in the older age groups (2). 1. Fassnacht M, Arlt W, Bancos I, et al.

Background: The aim of the study was to investigate changes in self-rated health (SRH) between different age groups and sexes over a 20-year period. Methods: Data were retrieved from the large longitudinal Health Survey of North Trøndelag, Norway, which includes data collected from more than 190,000 participants aged 20–70+ years between the years 1984 and 2008. Data were analysed using logistic regression and adjusted for sex. Results: From 1984 to 2008, the odds of scoring higher on SRH decreased by 46% in the youngest age group (20–29 years) and increased by approximately 35% in the middle-aged and older age groups (40–70+ years). When considering sex differences, women in most age groups scored lower than the men on their SRH. Conclusions: Our finding suggest a trending shift in SRH, with a reduction in the youngest age group (20–29 years) and an increase in the middle-aged and older age groups (40–70+ years). Despite the sex differences being small, our data indicate that in most age groups, women tend to score lower than men on their SRH. Future studies should focus on these trends to understand better the mechanisms underlying these changes in SRH and to follow future trends to see if the trend is reinforced or diminished.

Abstract Background Ensuring the quality of anthropometry data is paramount for getting accurate estimates of malnutrition prevalence among children aged 6–59 months in humanitarian and refugee settings. Previous reports based on data from Demographic and Health Surveys suggested systematic differences in anthropometric data quality between the younger and older groups of preschool children. Methods We analyzed 712 anthropometric population-representative field surveys from humanitarian and refugee settings conducted during 2011–2018. We examined and compared the quality of five anthropometric indicators in children aged 6–23 months and children aged 24–59 months: weight for height, weight for age, height for age, body mass index for age and mid-upper arm circumference (MUAC) for age. Using the z-score distribution of each indicator, we calculated the following parameters: standard deviation (SD), percentage of outliers, and measures of distribution normality. We also examined and compared the quality of height, weight, MUAC and age measurements using missing data and rounding criteria. Results Both SD and percentage of flags were significantly smaller on average in older than in younger age group for all five anthropometric indicators. Differences in SD between age groups did not change meaningfully depending on overall survey quality or on the quality of age ascertainment. Over 50% of surveys overall did not deviate significantly from normality. The percentage of non-normal surveys was higher in older than in the younger age groups. Digit preference score for weight, height and MUAC was slightly higher in younger age group, and for age slightly higher in the older age group. Children with reported exact date of birth (DOB) had much lower digit preference for age than those without exact DOB. SD, percentage flags and digit preference scores were positively correlated between the two age groups at the survey level, such as those surveys showing higher anthropometry data quality in younger age group also tended to show higher quality in older age group. Conclusions There should be an emphasis on increased rigor of training survey measurers in taking anthropometric measurements in the youngest children. Standardization test, a mandatory component of the pre-survey measurer training and evaluation, of 10 children should include at least 4–5 children below 2 years of age.

Abstract Background Novel coronavirus disease 2019 (COVID-19) causes an immense disease burden. Although public health countermeasures effectively controlled the epidemic in China, non-pharmaceutical interventions can neither be maintained indefinitely nor conveniently implemented globally. Vaccination is mainly used to prevent COVID-19, and most current antiviral treatment evaluations focus on clinical efficacy. Therefore, we conducted population-based simulations to assess antiviral treatment effectiveness among different age groups based on its clinical efficacy. Methods We collected COVID-19 data of Wuhan City from published literature and established a database (from 2 December 2019 to 16 March 2020). We developed an age-specific model to evaluate the effectiveness of antiviral treatment in patients with COVID-19. Efficacy was divided into three types: (1) viral activity reduction, reflected as transmission rate decrease [reduction was set as v (0–0.8) to simulate hypothetical antiviral treatments]; (2) reduction in the duration time from symptom onset to patient recovery/removal, reflected as a 1/γ decrease (reduction was set as 1–3 days to simulate hypothetical or real-life antiviral treatments, and the time of asymptomatic was reduced by the same proportion); (3) fatality rate reduction in severely ill patients (fc) [reduction (z) was set as 0.3 to simulate real-life antiviral treatments]. The population was divided into four age groups (groups 1, 2, 3 and 4), which included those aged ≤ 14; 15–44; 45–64; and ≥ 65 years, respectively. Evaluation indices were based on outbreak duration, cumulative number of cases, total attack rate (TAR), peak date, number of peak cases, and case fatality rate (f). Results Comparing the simulation results of combination and single medication therapy s, all four age groups showed better results with combination medication. When 1/γ = 2 and v = 0.4, age group 2 had the highest TAR reduction rate (98.48%, 56.01–0.85%). When 1/γ = 2, z = 0.3, and v = 0.1, age group 1 had the highest reduction rate of f (83.08%, 0.71–0.12%). Conclusions Antiviral treatments are more effective in COVID-19 transmission control than in mortality reduction. Overall, antiviral treatments were more effective in younger age groups, while older age groups showed higher COVID-19 prevalence and mortality. Therefore, physicians should pay more attention to prevention of viral spread and patients deaths when providing antiviral treatments to patients of older age groups.

Purpose: The purpose of this study was to compare the clinical characteristics and outcomes of hormone receptor-positive (HR+) human epidermal growth factor 2-negative (HER2–) breast cancer among elderly patients (over 65 years old) and younger patients.Methods: This was a retrospective cohort study of 328 patients who were treated for breast cancer at Pusan National University Yangsan Hospital between January 2009 and December 2014. Tumor characteristics, surgical methods, and survival outcomes were compared between the two age groups (<65 and ≥65 years old). Kaplan-Meier curves for disease-free survival (DFS) and overall survival (OS) were also constructed according to the age groups.Results: Among the 328 patients with HR+ HER2– breast cancer, 184 (56.1%) were <65 years old and 144 (43.9%) were ≥65 years old. Breast cancer stages were similar between the two age groups, but the older patients were treated less often with chemotherapy (81% vs. 66%, P=0.002). During the follow-up period, 17 deaths and 36 cases of recurrence or metastasis were reported. There was no difference in DFS between the two groups (P=0.840); however, the OS of the older age group was significantly lower than that of the younger age group (P=0.015).Conclusion: This study suggested that HR+ HER2– breast cancer patients belonging to the two age groups had no significant difference in DFS. However, older age is an independent factor affecting OS rate. Therefore, even if patients are old, but their physical condition is satisfactory, standard and active treatment may be necessary, similar to that given to younger patients.

Abstract Background: The purpose of the present study is to investigate the frequency and amount of extension of the maxillary sinus to the anterior region and to evaluate the vertical distance between the maxillary sinus floor and canine apices.Methods: Cone beam computed tomographic images of 300 individuals (154 males and 146 females) over 20 years (with mean age of 35.12 ± 8.40 years) were evaluated. The subjects were categorized into three age groups (20-30, 30-40 and 40-50 years). When maxillary sinus extended to the canine area, the vertical distance between them were recorded and their relationship were classified into three types: I (> 2 mm distance), II (2 mm < distance or in-contact) and III (interlock). Results: 413 out of 600 maxillary sinuses (68.8%) were extended into the canine area or beyond. Among them, 15 maxillary sinuses pneumatized into the incisor area (2.5%). The prevalence of the maxillary sinuses extended to the anterior region of the jaw was not significantly different between genders, but it was significantly less frequent in older age group and more frequent in the left side. The mean amount of anterior extension of maxillary sinus (mm) was significantly lower in older age group. Type I was the most frequent vertical relationship between the maxillary sinuses and canine apices with no significant difference in gender, side and age groups.Conclusions: Most of the maxillary sinuses extended to the canine area. Maxillary sinus extended into incisor area with the frequency of 2.5% . The amount of extension of the maxillary sinus to the anterior region and its vertical distance with canine apices decreased in older age group.
