Does age affect symptom recovery after sports-related concussion? A study of high school and college athletes

Object Sport-related concussions (SRCs) in high school and college athletes represent a significant public health concern. Research suggests that younger athletes fare worse symptomatically than older athletes after an SRC. Using reliable change index (RCI) methodology, the authors conducted a study to determine if there are age-related differences in number, severity, and resolution of postconcussion symptoms. Methods Between 2009 and 2011, baseline measures of neurocognitive functions and symptoms in high school and college athletes were entered into a regional database. Seven hundred forty of these athletes later sustained an SRC. Ninety-two athletes in the 13- to 16-year-old group and 92 athletes in the 18- to 22-year-old group were matched for number of prior concussions, sex, biopsychosocial variables, and days to first postconcussion testing and symptom assessment. A nonparametric Mann-Whitney U-test was used to compare the severity of each of 22 symptoms comprising the Total Symptom Scale (TSS) at baseline and first postconcussion test. To obtain a family-wise p value of 0.05 for each test, the significance level for each symptom comparison was set at an alpha of 0.05/22 = 0.0023. The number of days to return to baseline TSS score was compared using the RCI methodology, set at the 80% confidence interval, equal to a change in raw score of 9.18 points on the TSS. Results There was no statistically significant difference in symptom presence, symptom severity, and total symptoms between the age groups at baseline or at postconcussion testing. There was no statistically significant difference in return to baseline symptom scores between the age groups. Conclusions Using RCI methodology, there was no statistically significant difference between younger and older athletes in return to baseline symptoms postconcussion.

Two Age Groups

Background: It is well accepted that a single standard of craniofacial norms is not appropriate for application to diverse racial and ethnic groups, even for different sex and ages in same ethnic group. So it is necessary to develop craniofacial norms for different groups based on above factors. The present study was designed to establish the baseline measurements of the lower jaw and orolabial anthropometrical parameters and indices, and also to evaluate the differences (if any) on age related morphological variations of adult Bangladeshi Buddhist Chakma females. Methods: The study was descriptive, observational and cross-sectional in nature with some analytical components. The study group consisted of a convenient sample of 100 adult Bangladeshi Buddhist Chakma females; categorized into two groups 25 to 35 years (n = 70) and 35 to 45 years (n = 30). Variables were measured using physical and photographic procedures. Indices were calculated from those variables. An independent t test was performed to evaluate if there was any significant difference in measurements between the two age groups setting a p value of <0.05 as statistically significant. Results: All measurements show statistically non significant difference between two age groups except philtrum length (p = 0.02) and upper vermilion height to philtrum length index (p = 0.03). Conclusions: The result of this study can be useful for anatomists and anthropologists to serve as a basic framework for estimating the standard of lower jaw and orolabial dimensions of this population and also to compare the craniofacial dimensions of other ethnic groups of Bangladesh with this ethnic group.

Before And After

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

BACKGROUND Seroprevalence of IgG antibodies against SARS-CoV-2 is an important tool to estimate the true extent of infection in a population. However, seroprevalence studies have been scarce in South East Asia including India, which, as of now, carries the third largest burden of confirmed cases in the world. The present study aimed to estimate the seroprevalence of anti-SARS-CoV-2 IgG antibody among hospitalized patients at one of the largest government hospital in India OBJECTIVE The primary objective of this study is to estimate the seroprevalence of SARS-CoV-2 antibody among patients admitted to the Medicine ward and ICU METHODS This cross-sectional study, conducted at a tertiary care hospital in North India, recruited consecutive patients who were negative for SARS-CoV-2 by RT-PCR or CB-NAAT. Anti-SARS-CoV-2 IgG antibody levels targeting recombinant spike receptor-binding domain (RBD) protein of SARS CoV-2 were estimated in serum sample by the ELISA method RESULTS A total of 212 hospitalized patients were recruited in the study with mean age (±SD) of 41.2 (±15.4) years and 55% male population. Positive serology against SARS CoV-2 was detected in 19.8%patients(95% CI 14.7-25.8). Residency in Delhi conferred a higher frequency of seropositivity 26.5% (95% CI 19.3-34.7) as compared to that of other states 8% (95% CI 3.0-16.4) with p-value 0.001. No particular age groups or socio-economic strata showed a higher proportion of seropositivity CONCLUSIONS Around, one-fifth of hospitalized patients, who were not diagnosed with COVID-19 before, demonstrated seropositivity against SARS-CoV-2. While there was no significant difference in the different age groups and socio-economic classes; residence in Delhi was associated with increased risk (relative risk of 3.62, 95% CI 1.59-8.21)

Background: Although eye injuries constitute a small percentage of high school and college sports injuries, they have the potential to be permanently debilitating. Hypothesis: Eye injury rates will vary by sport, sex, and between the high school and college age groups. Study Design: Descriptive epidemiology study. Level of Evidence: Level 3. Methods: Data from eye injury reports in high school and college athletes were obtained from the National High School Sports-Related Injury Surveillance System, High School Reporting Information Online (HS RIO) database over a 10-year span (2005-2006 through 2014-2015 school years) and the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) over an 11-year span (2004-2005 through 2014-2015 school years). Injury rates per 100,000 athlete-exposures (AEs), injury rate ratios (RRs), and 95% CIs were calculated. Distributions of eye injuries by diagnosis, mechanism, time loss, and surgery needs were also examined. Results: A total of 237 and 273 eye injuries were reported in the HS RIO and the NCAA ISP databases, respectively. The sports with the highest eye injury rates (per 100,000 AEs) for combined high school and college athletes were women’s basketball (2.36), women’s field hockey (2.35), men’s basketball (2.31), and men’s wrestling (2.07). Overall eye injury rates at the high school and college levels were 0.68 and 1.84 per 100,000 AEs, respectively. Eye injury rates were higher in competition than practice in high school (RR, 3.47; 95% CI, 2.69-4.48) and college (RR, 3.13; 95% CI, 2.45-3.99). Most injuries were contusions (high school, 35.9%; college, 33.3%) and due to contact (high school, 89.9%; college, 86.4%). Only a small percentage of injuries resulted in time loss over 21 days (high school, 4.2%; college, 3.0%). Conclusion: Eye injury rates and patterns vary by sport, sex, and between the high school and college age groups. Although severe injuries do occur, most eye injuries sustained by high school and college athletes are minor, with limited time loss and full recovery. Clinical Relevance: Additional focus needs to be placed on preventing eye injuries at the collegiate level in women’s and men’s basketball, women’s field hockey, and men’s wrestling.

Background: Handwriting is a uniquely human trait which progresses and evolves during lifetime and declines with age. The aim of the present paper is to assess variation in handwriting features with age among female writers of select population groups of Delhi, India (for roman script). Method: A total of 405 handwritten samples were obtained from female (n=405) writers in the age range of 14-60 years. Writers were stratified into three age groups (≤ 18 years, 19-38 years and ≥39 years) in accordance to population group. Macro- and micro-features of handwriting were extracted from the scanned handwritten samples. These features were subjected to statistical analysis in the objective driven research. Result: The mean difference among age groups for pen pressure, height of handwriting and handwriting connectivity was statistically significant (p < 0.001). Significant difference was also observed among age groups for all micro-features of handwriting selected in the present study, namely, nature of ‘i’ – dot (p < 0.001), nature of lower loop of ‘g’ (p < 0.01); nature of‘d’- stem (p < 0.01), nature of ‘m’-hump (p < 0.05) and ‘r’- shape (p < 0.001). Conclusion: The present study showed that there was a significant variation in both macro- and micro- features of handwriting with respect to age of the writer. Pen pressure, height of handwriting and handwriting connectivity were prominent macro-features that addressed age related variation in handwriting. In addition, significant variation was observed among age groups for all micro-features of handwriting selected in the present study. The present study has immense forensic significance as it can assist to analyze age of the writer on the basis of handwriting characteristics.

Introduction. Health - is a complex and at the same integral multivariable dynamic state, developing in the process of realization of the genetic potential in a particular social and ecological environment, which permits a person to carry out its biological and social functions. Material and methods Health indices deteriorate with age. In this situation, special attention should be paid to older age groups. However, recent studies prefer to investigate young people. Data about health status of different age groups is not well investigated. Survey of 415 women aged 20 to 59 years residing on Yaroslavl region has been performed. Evaluation of age-related changes in health indices included questionnaire, morphological and functional examination, definition of physical development and adaptative potential according to the calculated indices and reference values. Results. The study examined the dynamics of health indices and established a statistically significant difference in the gain in body weight, blood pressure, total blood cholesterol, decreased lung capacity relative to body mass and adaptive capacity of the cardiovascular system with the age. Analysis of the incidence showed that chronic diseases incidence has increased from 56% in the 20-29 years group to 88% among 50-59 years old persons. Diseases of cardiovascular and musculoskeletal system (48-49%) become predominant pathology with age. Evaluation of lifestyle shows that poor physical activity and sleep disorders were registered in 77% and 32% respectively regardless of age. Eating disorders were registered in 41% patients aged of 20-29 years. Ratio tobacco users decreased from 23% to 10% with age, while the number of cigarettes smoked per day was increased. Сonclusion. The study established the negative dynamics of health indices to be typical for women aged 20-59 years, while the rate of deterioration exceeds the average one in the Russian population. Self-preservation behavior is not predominant in all age groups, it is typical only for 3% of young women and 11-15% of other groups.

ObjectiveThe objective of this study was to validate the computerized Symbol Digit Modalities Test (c-SDMT) in a Swiss pediatric cohort, in comparing the Swiss sample to the Canadian norms. Secondly, we evaluated sex effects, age-effects, and test–retest reliability of the c-SDMT in comparison to values obtained for the paper and pencil version of the Symbol Digit Modalities Test (SDMT).MethodsThis longitudinal observational study was conducted in a single-center setting at the University Children’s Hospital of Bern. Our cohort consisted of 86 children (45 male and 41 female) aged from 8 to 16 years. The cohort included both healthy participants (n = 38) and patients (n = 48) hospitalized for a non-neurological disease. Forty eight participants were assessed during two testing sessions with the SDMT and the c-SDMT.ResultsTest–retest reliability was high in both tests (SDMT: ICC = 0.89, c-SDMT: ICC = 0.90). A reliable change index was calculated for the SDMT (RCIp = −3.18, 14.01) and the c-SDMT (RCIp = −5.45, 1.46) corrected for practice effects. While a significant age effect on information processing speed was observed, no such effect was found for sex. When data on the c-SDMT performance of the Swiss cohort was compared with that from a Canadian cohort, no significant difference was found for the mean time per trial in any age group. Norm values for age groups between 8 and 16 years in the Swiss cohort were established.ConclusionNorms for the c-SDMT between the Swiss and the Canadian cohort were comparable. The c-SDMT is a valid alternative to the SDMT. It is a feasible and easy to administer bedside tool due to high reliability and the lack of motor demands.
