Abstract
Studies show that having physical disabilities is associated with lower life satisfaction (LS). People with disabilities have reduced opportunities and welfare compared with people without disabilities. During aging, disabilities may have different impact on LS. A question is whether disability duration plays a unique role by affecting LS or whether an association is caused by other factors. This study analyzed Norwegian panel data (N = 2,555) including people aged 40 to 79 years at baseline to examine how disability and its duration affect LS at follow-up 5 years later, controlling for sociodemographic, socioeconomic, and health factors using ordinary least-squares regression. People with disabilities had lower LS than those without disabilities. Disability duration affected LS among people aged 40 to 49 years and 60 to 69 years, but the association was due to the lack of social, economic, and health resources. The meaning of duration of disability and challenges of reduced resources will vary with life stages.

Abstract
Background While circulation of respiratory syncytial virus (RSV) results in high rates of hospitalization, particularly among young children and elderly individuals, little is known about the role of different age groups in propagating annual RSV epidemics. Methods We evaluate the roles played by individuals in different age groups during RSV epidemics in the United States between 2001 and 2012, using the previously defined relative risk (RR) statistic estimated from the hospitalization data from the Healthcare Cost and Utilization Project. Transmission modeling was used to examine the robustness of our inference method. Results Children aged 3-4 years and 5-6 years each had the highest RR estimate for 5 of 11 seasons included in this study, with RSV hospitalization rates in infants being generally higher during seasons when children aged 5-6 years had the highest RR estimate. Children aged 2 years had the highest RR estimate during one season. RR estimates in infants and individuals aged ≥11 years were mostly lower than in children aged 1-10 years. Highest RR values aligned with groups for which vaccination had the largest impact on epidemic dynamics in most model simulations. Conclusions Our estimates suggest the prominent relative roles of children aged ≤10 years (particularly among those aged 3-6 years) in propagating RSV epidemics. These results, combined with further modeling work, should help inform RSV vaccination policies.

Abstract
Higher risk taking is particularly characteristic for males between 15 and 35 years, the age when intrasexual competition is the strongest. This fitness-maximizing strategy, however, also has negative consequences; previous data revealed that males have a significantly higher tendency to die in accidents. This retrospective study aimed to assess whether age-related risk taking, often associated with the reproductive competition between males, and referred to as the Young Male Syndrome (YMS), may play a role in the high incidence of severe traumatic brain injury (sTBI) in young males. Derived from the available evidence and the main assumptions of the YMS, we expected that men, especially when they are in the age when their reproductive potential peaks, are more likely to suffer sTBI from highly risky behaviors that also lead to higher mortality. It was also expected that alcohol intoxication makes the demographic pattern of sTBI even more similar to what previous research on the YMS implies. We analyzed demographic data of patients with sTBI (N = 365) registered in a clinical database. To this end, we built Generalized Linear Mixed Models (GLMM) to reveal which of the demographic characteristics are the best predictors for risky behaviors leading to sTBI and death as a consequence of the injury. The data suggest that younger people acquired sTBI from riskier behaviors compared to members of older age groups, irrespective of their sex. Moreover, being male and being alcohol intoxicated also contributed significantly to risk-taking behavior. Mortality rate after the injury, however, increased with the age of the patient and did not depend on the riskiness of the behavior. The results indicate that the demographic distribution of the specific patient population in our focus cannot be simply explained by the YMS. However, higher incidence rates of males among the patients are in line with the core assumptions of the YMS. These data indicate that epidemiological studies should also take into consideration evolutionary theories and highlight the importance of age and sex specific prevention strategies.

Abstract
Biotransformation rates extrapolated from in vitro data are used increasingly in human physiologically based pharmacokinetic (PBPK) models. This practice requires use of scaling factors, including microsomal content (mg of microsomal protein/g liver, MPPGL), enzyme specific content, and liver mass as a fraction of body weight (FVL). Previous analyses indicated that scaling factor variability impacts pharmacokinetic (PK) outcomes used in adult population dose-response studies. This analysis was extended to pediatric populations because large inter-individual differences in enzyme ontogeny likely would further contribute to scaling factor variability. An adult bromodichloromethane (BDCM) model (Kenyon, E. M., Eklund, C., Leavens, T. L., and Pegram, R. A. (2016a). Development and application of a human PBPK model for bromodichloromethane (BDCM) to investigate impacts of multi-route exposure. J. Appl. Toxicol. 36, 1095-1111) was re-parameterized for neonates, infants, and toddlers. Monte Carlo analysis was used to assess the impact of pediatric scaling factor variation on model-derived PK outcomes compared with adult findings. BDCM dose metrics were estimated following a single 0.05-liter drink of water or a 20-min bath, under typical (5 µg/l) and plausible higher (20 µg/l) BDCM concentrations. MPPGL, CYP2E1, and FVL values reflected the distribution of reported pediatric population values. The impact of scaling factor variability on PK outcome variation was different for each exposure scenario, but similar for each BDCM water concentration. The higher CYP2E1 expression variability during early childhood was reflected in greater variability in predicted PK outcomes in younger age groups, particularly for the oral exposure route. Sensitivity analysis confirmed the most influential parameter for this variability was CYP2E1, particularly in neonates. These findings demonstrate the importance of age-dependent scaling factor variation used for in vitro to in vivo extrapolation of biotransformation rates.

Abstract
BACKGROUND/OBJECTIVES The treatment of type 2 diabetes in older adults requires special considerations including avoidance of hypoglycemia, yet variation in diabetes treatment with aging is not well understood. In this study, we compared nationally representative diabetes treatment patterns and trends between older adults (≥65 y) and younger adults (30-64 y). DESIGN Repeated cross-sectional physician surveys from 2006 to 2015. SETTING The National Ambulatory Medical Care Survey, an annual probability sample of visits to office-based US physicians. PARTICIPANTS Adults with type 2 diabetes using one or more diabetes medications. MEASUREMENTS Proportions of visits in which patients treated with each diabetes medication class were compared between older and younger adults in 2-year intervals. RESULTS From 2006 to 2015, the average number of yearly visits for older and younger adults was 25.4 million and 24.2 million, respectively. In 2014-2015, visits for older compared with younger adults involved less use of metformin (56.0% vs 70.0%; p < .001) and glucagon-like peptide 1 receptor agonists (2.9% vs 6.2%; p = .004), and more use of long-acting insulin (30.2% vs 22.4%; p = .017); other classes were used similarly. During the study period, long-acting insulin use increased markedly in older adults, particularly between 2010 and 2015 where it rose from 12.5% to 30.2% of visits (P-trend <.001). In younger adult visits, long-acting insulin use increased modestly (17.2% to 22.4%) and at a slower rate compared with older adult visits (p < .001). CONCLUSION The ambulatory treatment of type 2 diabetes differs between older and younger adults, with the treatment of older adults characterized by low use of newer diabetes medications and a greater and rapidly increasing use of long-acting insulin. These findings call for further research clarifying the comparative effectiveness and safety of newer diabetes medications and long-acting insulin to optimize diabetes care for older patients.

Abstract
Age-related changes in the brain connectivity of healthy older adults have been widely studied in recent years, with some differences in the obtained results. Most of these studies showed decreases in general functional connectivity, but they also found increases in some particular regions and areas. Frequently, these studies compared young individuals with older subjects, but few studies compared different age groups only in older populations. The purpose of this study is to analyze whole-brain functional connectivity in healthy older adult groups and its network characteristics through functional segregation. A total of 114 individuals, 48 to 89 years old, were scanned using resting-state functional magnetic resonance imaging in a resting state paradigm and were divided into six different age groups (< 60, 60–64, 65–69, 70–74, 75–79, ≥ 80 years old). A partial correlation analysis, a pooled correlation analysis and a study of 3-cycle regions with prominent connectivity were conducted. Our results showed progressive diminution in the functional connectivity among different age groups and this was particularly pronounced between 75 and 79 years old. The oldest group (≥ 80 years old) showed a slight increase in functional connectivity compared to the other groups. This occurred possibly because of compensatory mechanism in brain functioning. This study provides information on the brain functional characteristics of every age group, with more specific information on the functional progressive decline, and supplies methodological tools to study functional connectivity characteristics. Approval for the study was obtained from the ethics committee of the Comisión de Bioética de la Universidad de Barcelona (approval No. PSI2012-38257) on June 5, 2012, and from the ethics committee of the Barcelona’s Hospital Clínic (approval No. 2009-5306 and 2011-6604) on October 22, 2009 and April 7, 2011 respectively.

Abstract
Retinoids continue to be the main mean for the treatment of photoaging as they are able to align not only the various wrinkles but also to reduce skin pigmentation. Retinol serves as a reserve turned into an active substance by the cell itself in the required amount that triggers the expression of genes responsible for the development of epithelial tissue. The aim of the research therefore was to study the dynamics of the functional parameters of the skin after peeling with retinol in different age groups. 58 patients who had been treating with chemical peeling with retinol were under observation. All the patients were divided into two groups by age: the 1st group - 29 women from 30 to 45 years (38,51±4,34 years), the 2nd group - 29 women from 46 to 60 years (52,97±5,34 years). We studied the moisture content, acid-base balance, pigmentation, erythema degree, skin salinity and elasticity before treatment, 14 and 28 days after peeling. It was found that peeling with retinol bleached the skin better in the patients of the older age group, although their skin was more sensitive to the components of peeling. In the study of elasticity in the older age group, peeling with retinol reduced the extensibility, significantly increased the tone, viscosity and improved the total elasticity of the skin. Chemical peeling with retinol had the best effect on the skin in patients 46-60 years.

Abstract
BACKGROUND: Suicidal ideation is a strong antecedent of suicidal behavior, associated with increased likelihood of suicide. Thus, suicidal ideation serves to identify which groups are at more risk of suicide and has policy implications for targeting groups to prevent suicide. AIMS: A substantial body of research has addressed potential determinants of suicide ideation in Korea. Little attention has been paid, however, to analyzing the extent to which socioeconomic attainments (education, household income, and employment status) are associated with risk of suicidal ideation, drawing on nationally representative data. METHODS: Data were drawn from the 2012 Korea Welfare Panel Study (KOWEPS). Among the 12,606 respondents, the findings are based on 1,500 young adults (age 18-35) and 3,469 middle-aged adults (age 36-55) who answered a question about suicidal ideation. RESULTS: For young adults, respondents from 2-year and 4-year colleges and higher had lower probabilities of suicidal ideation compared with respondents from high school. People out of the labor force also exhibited an elevated risk of suicidal ideation compared with those in waged employment. Middle-aged adults displayed different patterns. Middle-aged respondents from 4-year colleges or higher had an increased likelihood of suicidal ideation. The likelihood of reporting suicidal ideation was predicted to decrease as household income increased only for middle-aged adults. CONCLUSIONS: The information about suicidal ideation was obtained from only one question of self-response, which limits the validity of the suicidal ideation measurement. The cross-sectional setting of the data prevents us from estimating causal relationships. Nevertheless, the findings imply that age-specific policy should be implemented to ameliorate differential risk for suicidal ideation and benefit public mental health in the long run.

Abstract
OBJECTIVES To assess the diagnostic value of cervical cytology and HPV HR DNA testing for the diagnosis of low grade and high-grade squamous intraepithelial lesions across different age groups. MATERIAL AND METHODS The study included 1103 patients, age 25-70 years. All patients underwent in-depth diagnostic tests following either an abnormal Pap test result or a clinically suspicious cervical lesion. In all women the following examinations were performed: a molecular test detecting 14 high-risk types of HPV, a colposcopy examination, as well as directed-biopsy of the cervix. The studied population was subdivided into four age groups. RESULTS It was observed that the percentage of high grade squamous intraepithelial lesions (HSIL) and cancers increased with women's age. Sensitivity of both methods for detecting high-grade squamous intraepithelial lesions was highest for women aged 40-49 years. Sensitivity values of HPV testing was higher than that of cervical cytology among women under age 50. CONCLUSIONS Specificity of HPV testing increased significantly with age of women and was several fold higher across all age groups than the specificity of cervical cytology.

Abstract
Introduction Whether or not age is a predictor of kidney cancer survival is currently unknown but debated. It is also unknown whether improved kidney cancer survival is associated with age with particular clinicopathologic characteristics. The aim of this study was to evaluate kidney cancer survival in four age-based subgroups of patients by analyzing the Surveillance, Epidemiology, and End Results-registered database. Methods Age-based survival disparity by sex, race, marital status, year of diagnosis, pathological grade, histological type, and stage was measured. The impact of age and further parameters on disease specific mortality was evaluated by multivariate Cox proportional hazards regression analyses. Results Results showed that 8-year cancer-specific survival was 79.6% in those aged ≤49 years, 70.6% in those aged 50-64 years, 65.3% in those aged 65-74 years, and 56.0% in those aged 75-84 years. These differences were significant as judged by a univariate log-rank test (P<0.001) and multivariate Cox regression (P<0.001). Age-based survival improvement was most obvious in patients diagnosed from 2005 to 2009 and with the following clinicopathologic characteristics: female, white race, low pathological grade, and localized stage. There was no obvious disparity of age-based survival improvement with regard to marital status or histologic type. No age-based survival improvement was observed in patients of the black race, pathological grade IV, or distant stage (P=0.05, P=0.07, and P=0.07, respectively). Conclusion These data suggest that age is an independent prognostic factor for survival in patients with kidney cancer and that age-based survival improvement is associated with particular clinicopathologic characteristics.

Abstract
PURPOSE Longitudinal cohort studies and guidelines demonstrate that prostate specific antigen 1 ng/ml or greater in younger patients confers an increased risk of delayed prostate cancer death. At our institution we have used an aggressive biopsy strategy in younger patients with prostate specific antigen 1 ng/ml or greater. Our objective was to determine the proportion of detected cancer and specifically clinically significant cancer by this strategy. MATERIALS AND METHODS The prostate biopsy database at Princess Margaret Cancer Centre was queried for patients younger than 50 years who underwent a first prostate biopsy between 2000 and 2016. We included only patients who underwent prostate biopsy due to prostate specific antigen 1 ng/ml or greater and those with a suspicious digital rectal examination, a positive family history or a suspicious lesion on transrectal ultrasound. All clinical and pathological parameters were analyzed. Patients were stratified according to specific prostate specific antigen values. Multivariable logistic regression was performed to ascertain predictors of any prostate cancer diagnosis and of clinically significant prostate cancer. RESULTS Of the 199 patients who met study inclusion criteria 37 (19%) were diagnosed with prostate cancer and 8 (22%) had a Gleason score of 7 or greater. Of those diagnosed with prostate cancer 25 (68%) had prostate specific antigen 1.5 ng/ml or greater and all men with a Gleason score of 7 or greater had prostate specific antigen 1.5 ng/ml or greater. Notably 19 patients (51%) had prostate cancer exceeding the Epstein criteria for active surveillance. Factors predicting prostate cancer included a positive family history, rising prostate specific antigen and lower prostate volume. CONCLUSIONS Our results justify adopting an aggressive prostate biopsy strategy in men younger than 50 years with prostate specific antigen 1.5 ng/ml or greater while patients with prostate specific antigen less than 1.5 ng/ml are unlikely to have significant cancer. Special attention should be given to patients with a smaller prostate and a positive family history.

Abstract
BACKGROUND The aim of the study was to analyse changes in the size of the corpus callosum (CC) depending on age and sex and to establish the reference values of the morphometric indices of the CC in the Polish population. MATERIALS AND METHODS The results of magnetic resonance studies of 1108 patients performed in the years 2010-2014 were analysed. Two independent radiologists evaluated cerebral images to exclude deviations from normal state. In patients divided according to sex and to 10 age groups, measurements of CC and brain dimensions were made and morphometric indices were calculated. RESULTS The results of measurements related to the following parameters: lengths of longitudinal cross-section of CC (CD), CC thickness in the narrowest place - isthmus (EF), the largest linear dimension of the brain from the frontal pole to the occipital pole (AB), the longitudinal cross-section area of the CC (A1) and cerebral cross-section area (A2) as well as CD/AB and A1/A2 ratios are summarised in 7 figures and 3 tables. CONCLUSIONS It was demonstrated, that in all age groups there are statistically significant differences in the values of the analysed parameters and ratios of CC size. It was indicated, that there are no statistically significant differences between men and women in the CD, EF, and A1 parameters related to CC size, and the profiles of variations of these parameters are very similar. It was proved that the- re are statistical differences between women and men in parameters/indicators concerning of the brain size.

Abstract
Aim We analyzed the incidence and prognosis of thromboembolism associated with combined oral contraceptives (COCs) by age groups in Japan. Methods A total of 581 events of venous thromboembolism (VTE) and arterial thromboembolism (ATE) associated with COCs were analyzed from the Pharmaceuticals and Medical Devices Agency database from 2004 to 2013. In a statistical analysis, a good‐prognosis group included recovery cases and a poor‐prognosis group involved unrecovered cases with some sequela and fatal cases. The significant difference between these two groups was calculated by Pearson's chi‐square test, and the age‐specific tendency and the trend of differences in prognosis according to different hormonal contraceptives were examined by Cochran–Armitage trend test. Results A total of 543 events were analyzed except 38 events due to unknown age, in which DVT only was the most frequent, followed by cerebral infarction, PE with DVT, PE only, cerebral vein thromboses. ATE ratio for overall thromboembolism tended to increase with advancing age (P = 0.0041). Good‐prognosis group was common (291 cases in VTE and 83 cases in ATE), followed by poor‐prognosis group (46 cases in VTE and 34 cases in ATE). All ATE cases had a significantly poorer prognosis in comparison with all VTE cases (P < 0.0001). Types of progestin and age difference, however, showed no trend in the differences between good‐prognosis group and poor‐prognosis group (P = 0.3548 and P = 0.6097). Conclusion Thromboembolic events were the most frequent in the 40s. The ATE ratio for overall thromboembolism tended to increase with advancing age. All ATE cases had a significantly poorer prognosis in comparison with all VTE cases.

Abstract
Background There is limited information on the roles of different age groups in propagating pertussis outbreaks, and on the impact of vaccination on pertussis transmission in the community. Methods The relative roles of different age groups in propagating the 2012 pertussis outbreak in Wisconsin were evaluated using the relative risk (RR) statistic that measures the change in the group’s proportion among all detected cases before vs after the epidemic peak. The impact of vaccination in different age groups against infection (that is potentially different from the protective effect against detectable disease) was evaluated using the odds ratios (ORs), within each age group, for being vaccinated vs undervaccinated before vs after the outbreak’s peak. Results The RR statistic suggests that children aged 13–14 years played the largest relative role during the outbreak’s ascent (with estimates consistent across the 3 regions in Wisconsin that were studied), followed by children aged 7–8, 9–10, and 11–12 years. Young children and older teenagers and adults played more limited relative roles during the outbreak. Results of the vaccination status analysis for the fifth dose of DTaP (for children aged 7–8 years: OR, 0.44; 95% confidence interval [CI], 0.23–0.86; for children aged 9–10 years: OR, 0.51; 95% CI, 0.27–0.95); and for Tdap for children aged 13–14 years (OR, 0.38, 95% CI, 0.16–0.89) are consistent with protective effect against infection. Conclusions While our epidemiological findings for the fifth dose of DTaP and for Tdap are consistent with protective effect against infection, further studies, including those estimating vaccine effectiveness against infection/transmission to others particularly for pertussis vaccines for adolescents, are needed to evaluate the impact of vaccination on the spread of pertussis in the community.

Abstract
INTRODUCTION Tuberculosis continues to be a major health problem in the world with an incidence of more than 10 million cases in 2015. There are factors that change the risk of developing the disease after infection, as well as the presentation of the disease. OBJECTIVE To determine the main comorbidities and demographic, clinical and microbiological characteristics of tuberculosis adult patients in Argentina from a gender and age perspective. MATERIALS AND METHODS We conducted a cross-sectional study in urban referral hospitals for patients with tuberculosis. We included tuberculosis patients of 15 years or more of age who were hospitalized or treated in outpatient clinics with bacteriologically confirmed pulmonary or extrapulmonary forms of the disease, as well as those who, although not bacteriologically confirmed, had clinical and radiological characteristics consistent with tuberculosis. The study period was from August 1st, 2015 to August 31st, 2016. RESULTS We included 378 patients. The median age was 37 years. Male gender was associated with extrapulmonary tuberculosis, hospitalization, smoking, drug addiction and alcoholism. Tuberculosis and aids (22.6%) was related to drug use, admission into hospital, extrapulmonary tuberculosis, nonaddiction to tobacco, non-pathological radiology, absence of cavitation, and negative sputum smear microscopy. Patients less than 40 years of age had a higher rate of drug addiction and low weight, while those aged 40 or over had a higher proportion of diabetes, alcoholism and chronic obstructive pulmonary disease (COPD). CONCLUSIONS This study will help recognize tuberculosis patients' characteristics and comorbidities influencing the development and evolution of the disease from an age and gender perspective to enable the development of social and community-based strategies.

Effects of glenohumeral internal rotation deficit on baseball pitching among pitchers of different ages. J Shoulder Elbow Surg 2018; 27:599-605. [PMID: 29241660 DOI: 10.1016/j.jse.2017.09.001] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2017] [Revised: 08/29/2017] [Accepted: 09/09/2017] [Indexed: 02/01/2023]
Abstract
BACKGROUND Previous studies have reported that glenohumeral internal rotation deficit (GIRD) may increase the risk of shoulder injury. However, the effects of GIRD on baseball pitching among pitchers of different age groups are still unclear. METHODS The study participants were 24 high school and 24 university pitchers. For each age group, the pitchers were evenly divided into a GIRD group and a normal group. The pitching motion of each participant was captured using a motion analysis system at a sampling frequency of 300 Hz. The kinematics and kinetics of the throwing shoulder and trunk were quantified, and statistical differences between the groups were examined by 2-sample t tests. RESULTS For both age groups, significant differences were observed in shoulder external rotations of the GIRD and normal groups. Compared with the university pitchers in the normal group, the university pitchers with GIRD exhibited a greater shoulder loading and did more internal rotation work in the acceleration phase. The high school pitchers with GIRD showed a larger trunk tilt and less trunk rotation than the university pitchers with GIRD. However, the university pitchers with GIRD exhibited a larger shoulder posterior force and horizontal adduction torque than the high school pitchers with GIRD. CONCLUSION Pitchers with GIRD do change their pitching motions, and the greater resulting shoulder joint loading predisposes them to a greater risk of shoulder injury, especially among university pitchers.

[PMID: 29599724 PMCID: PMC5862813 DOI: 10.3389/fphys.2018.00226] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2017] [Accepted: 02/28/2018] [Indexed: 12/21/2022] Open
Abstract
Age-based prediction equations of maximal heart rate (HRmax), such as the popular formulas Fox's 220-age, or Tanaka's 208-0.7 × age, have been widely used in various populations. Surprisingly, so far these equations have not been validated in marathon runners, despite the importance of the role of HRmax for training purposes in endurance running. The aim of the present study was to examine the validity of Fox and Tanaka equations in a large sample of women and men recreational marathon runners. Participants (n = 180, age 43.2 ± 8.5 years, VO2max 46.8 mL/min/kg, finishers in at least one marathon during the last year) performed a graded exercise test on a treadmill, where HRmax was measured. Measured HRmax correlated largely with age in the total sample (r = −0.50, p < 0.001), women (r = −0.60, p < 0.001) and men (r = −0.53, p < 0.001). In women, a large main effect of method on HRmax (p = 0.001, η2 = 0.294) was shown with measured HRmax lower than Fox-HRmax (−4.8 bpm; −8.4, −1.3) and Tanaka-HRmax (−4.9 bpm; −8.1, −1.8). In men, a moderate effect of assessment method on HRmax was found (p = 0.001, η2 = 0.066) with measured HRmax higher than Fox-HRmax (+2.8; 1.0, 4.6), Tanaka-HRmax higher than Fox-HRmax (+1.2; 0.7, 1.7). Based on these findings, it was concluded that Fox and Tanaka' formulas overestimated HRmax by ~5 bpm in women, whereas Fox underestimated HRmax in men by ~3 bpm. Thus, we recommend the further use of Tanaka's formula in men marathon runners. In addition, exercise physiologists and sport scientists should consider the observed differences among various assessment methods when performing exercise testing or prescribing training program relying on HR.

Abstract
OBJECTIVE A cross-sectional study was conducted to investigate whether depression is associated with periodontal diseases in a representative sample of South Korean adults Methods: We used data from the sixth Korea National Health and Nutrition Examination Survey (KNHANES VI), conducted in 2014. We included in this study 4328 participants aged over 20 years (1768 males and 2560 females). Depression was assessed with the Patient Health Questionnaire (PHQ-9) and history of physician-diagnosed depression. Periodontal diseases were assessed a gingival bleeding, calculus and periodontal pockets. The data were analyzed using the chi-square test and multiple logistic regression. RESULTS People with any periodontal diseases tended to be old, male, married, low income, poor education, blue-collar occupation, diabetes mellitus, hypertension, overweight, smoking, not using dental floss or interdental brush in univariate analysis. Neither self-reported nor diagnosed depression was associated with the presence of any or severe periodontal disease in the total sample. In participants aged 20-29 years only, the presence of any periodontal disease was associated with self-reported depression (OR, 2.031; 95% CI, 1.011-4.078). In the same age group, the presence of severe periodontal disease was associated with both self-reported depression (OR, 6.532; 95% CI, 2.190-19.483) and diagnosed depression (OR, 7.729; 95% CI, 1.966-30.389). CONCLUSION Self-reported depression was significantly associated with the presence of any or severe periodontal disease, and diagnosed depression was significantly associated with severe periodontal diseases only in participants aged 20-29 years.

Abstract
BACKGROUND Knowledge of the prevalence of electrocardiographic abnormalities in a population is useful for interpreting the findings. The aim here was to assess the prevalence of electrocardiographic abnormalities and self-reported comorbidities and cardiovascular risk factors according to sex and age group among Brazilian primary care patients. DESIGN AND SETTING Observational retrospective study on consecutive primary care patients in 658 cities in the state of Minas Gerais, Brazil, whose digital electrocardiograms (ECGs) were sent for analysis to the team of the Telehealth Network of Minas Gerais (TNMG). METHODS All ECGs analyzed by the TNMG team in 2011 were included. Clinical data were self-reported and electrocardiographic abnormalities were stratified according to sex and age group. RESULTS A total of 264,324 patients underwent ECG examinations. Comorbidities and cardiovascular risk factors were more frequent among women, except for smoking. Atrial fibrillation and flutter, premature beats, intraventricular blocks, complete right bundle branch block and left ventricular hypertrophy were more frequent among men, and nonspecific ventricular repolarization abnormalities and complete left bundle branch block among women. CONCLUSION Electrocardiographic abnormalities were relatively common findings, even in the younger age groups. The prevalence of electrocardiographic abnormalities increased with age and was higher among men in all age groups, although women had higher frequency of self-reported comorbidities.

Abstract
Objective To assess age-dependent and regional differences in T2* relaxation measurements in hip joint cartilage of asymptomatic volunteers at 3 T. Design Three age cohorts (cohort 1: age 20-30 years, 15 individuals; cohort 2: age 30-40 years, 17 individuals; cohort 3: age 40-50 years, 15 individuals) were enrolled. T2* values were obtained in the central and peripheral cartilage of the acetabulum and the femoral head in 7 regions (anterior to superior and posterior). Results T2* did not differ among age cohorts in acetabular cartilage (cohort 1: 24.65 ± 6.56 ms, cohort 2: 24.70 ± 4.83 ms, cohort 3: 25.81 ± 5.10 ms, P = 0.10) and femoral head cartilage (cohort 1: 27.08 ± 8.24 ms, cohort 2: 25.90 ± 7.82 ms, cohort 3: 26.50 ± 5.61 ms, P = 0.34). Analysis of the regional T2* distribution pattern indicates increased T2* values in the anterior, anterior-superior, superior-anterior, and the posterior-superior aspects of acetabular and femoral head cartilage. For acetabular cartilage, higher values were observed in the central region (25.90 ± 4.80 ms vs. 24.21 ± 4.05 ms, P < 0.0001) whereas femoral head cartilage did not reveal such differences (26.62 ± 5.74 ms vs. 26.37 ± 5.89 ms, P = 0.44). Conclusions The T2* analysis of presumably healthy hip joint cartilage does not seem to be stratified according to age in this population. Regional T2* variation throughout hip joint cartilage is apparent in this modality.

Abstract
AIM The aim of the present study was to investigate the change in overall life satisfaction for different age groups and between genders over a 20-year period. METHODS Data from 1984 to 2008 were extracted from a large prospective longitudinal health study of Nord-Trøndelag (HUNT), Norway. The study included more than 176,000 participants ranging from 20 to 70+ years of age. Data were analysed using logistic regression and adjusted for gender. RESULTS The analyses revealed an increase in life satisfaction for all age groups from 1984-1986 (HUNT 1) to 1995-1997 (HUNT 2), with the highest levels being reached at 2006-2008 (HUNT 3). For all age groups, the data showed an increase of about 20% for the period from 1984-1986 (HUNT 1) to 1995-1997 (HUNT 2). From 1995-1997 (HUNT 2) to 2006-2008 (HUNT 3), the increase in overall life satisfaction was 16% for the younger age groups, and about 32% for the older age groups (40-69 and 70+ years). Women's scores for overall life satisfaction were higher for nearly all age groups when compared to men using HUNT 3 as a reference. CONCLUSIONS These findings suggest an increase in life satisfaction for all age groups from 1984 to 2008, especially for the older age group (40-69 and 70+ years). The data indicate that women score higher on life satisfaction for most age groups as compared to men.

Abstract
OBJECTIVE Hypothyroidism is more frequently diagnosed in women and older individuals. It has been suggested that the prevalence of hypothyroidism and the number of prescriptions for thyroid hormones are increasing. However, despite hypothyroidism being a common medical condition, contemporary data on prevalence, particularly across the various age groups, is limited. DESIGN Information regarding number of individuals diagnosed with treated hypothyroidism (defined as patients prescribed levothyroxine) across ten General Practices (total population of 66 843) in the North-East of England in 2016 was obtained in an anonymized manner. Total as well as age group-specific point prevalence rates were calculated. In addition, corresponding population data for the United Kingdom were acquired, and national total and age-specific hypothyroidism prevalence rates were estimated. RESULTS The overall prevalence of hypothyroidism in this community sample was 4.5% (n = 3004). Prevalence increased across the age groups from 0.1% in children aged 0-10 years to 15.1% in those aged more than 90 years. After adjusting for demographic differences between the North-East England and UK populations, it is estimated that the total UK-wide prevalence of hypothyroidism in 2016 is 3.6%; affecting more than 2.3 million individuals including nearly 800 000 individuals aged >70 years. CONCLUSIONS Hypothyroidism affects millions of individuals in the UK and is currently a prevalent diagnosis in more than 1 in 10 individuals aged above 70 years. As the population ages this number is likely to increase. The clinical and economic effects of current management strategies for hypothyroidism, particularly in the older population, need to be evaluated.

Abstract
Human hair of different age groups and foodstuff samples were collected in Beijing, China. The concerned metals—Cd, Cr, Pb, As, and Hg—were analyzed, and the metal levels in relation to age, gender, and dietary intake were further assessed. Results showed the highest level of the metals was shown by Pb, with an average concentration of 1.557 ± 0.779 mg/kg, followed by Cr (0.782 ± 0.394), Hg (0.284 ± 0.094), As (0.127 ± 0.078), and Cd (0.071 ± 0.032), following a decreasing order of Pb > Cr > Hg > As > Cd, which were all below the upper limit of normal values in China. The heavy metal concentrations varied greatly among different age groups, and higher concentrations for Cd, Cr, Pb, and As appeared in female hair, whereas higher Hg concentration were found in male hair, suggesting that age and gender were not crucial factors for assessing metal concentrations in human hair. The ingestion of cereals and vegetables were the main route by which heavy metals in the environment create hazardous health effects for local inhabitants, but the estimated metal intakes through food consumption were all lower than the proposed limit of Provisional Tolerable Weekly Intake (PTWI), indicating that heavy metals posed no health risks for the inhabitants. Furthermore, little relationship was found between metal intakes and the corresponding metal levels in hair. Nevertheless, the results of this study can be used to analyze the internal heavy metal burden in the resident population of Beijing area and can also serve as reference for further studies.

Abstract
Introduction A cochlear implant in adolescent patients with pre-lingual deafness is still a debatable issue. Objective The objective of this study is to analyze and compare the development of auditory speech perception in children with pre-lingual auditory impairment submitted to cochlear implant, in different age groups in the first year after implantation. Method This is a retrospective study, documentary research, in which we analyzed 78 reports of children with severe bilateral sensorineural hearing loss, unilateral cochlear implant users of both sexes. They were divided into three groups: G1, 22 infants aged less than 42 months; G2, 28 infants aged between 43 to 83 months; and G3, 28 older than 84 months. We collected medical record data to characterize the patients, auditory thresholds with cochlear implants, assessment of speech perception, and auditory skills. Results There was no statistical difference in the association of the results among groups G1, G2, and G3 with sex, caregiver education level, city of residence, and speech perception level. There was a moderate correlation between age and hearing aid use time, age and cochlear implants use time. There was a strong correlation between age and the age cochlear implants was performed, hearing aid use time and age CI was performed. Conclusion There was no statistical difference in the speech perception in relation to the patient's age when cochlear implant was performed. There were statistically significant differences for the variables of auditory deprivation time between G3 - G1 and G2 - G1 and hearing aid use time between G3 - G2 and G3 - G1.

Abstract
Objectives This study aimed to investigate factors affecting sarcopenia in different age groups among Korean adults aged 20 years or older. Methods In this secondary analysis, data were collected from records for 17,968, participants who participated in the Korea National Health and Nutrition Examination Survey during 2008–2011. Data were analyzed using multiple logistic regression to determine the associated factors of sarcopenia by age groups. Results The prevalence of sarcopenia increased significantly with age. Physical activity, blood pressure, waist circumference, triglycerides, vitamin D level were found to be factors significantly associated with sarcopenia in all age groups. Total energy intake was found to be a factor that is significantly associated with sarcopenia among the adults aged 20–39 years. Fasting glucose, suicidal ideation, perceived health status, mobility problem, pain/discomfort, total energy intake were found to be factors associated with sarcopenia in the adults aged 40–64 years. Sex, residential area, smoking, drinking, fasting glucose, osteoarthritis, fall experience, usual activity problem, protein intake were factors associated with sarcopenia in the adults over 65 years of age. Conclusion The findings show that sarcopenia in adults and the associated factors were different by age groups. Thus, these factors should be considered in the development of intervention programs for the care and prevention of sarcopenia, and such programs should be modified according to different age groups.

Abstract
PURPOSE Postoperative urinary retention is a common complication across surgical specialties. To our knowledge no literature to date has examined postoperative urinary retention as a predictor of long-term receipt of surgery for bladder outlet obstruction. MATERIALS AND METHODS We retrospectively reviewed the records of inpatients who underwent nonurological surgery in California between 2008 and 2010. Postoperative urinary retention during the index admission was identified, as was receipt of a bladder outlet procedure (transurethral prostate resection, prostate photoselective vaporization or suprapubic prostatectomy) at a subsequent encounter. Patients were matched using propensity scoring of demographics, comorbidities and surgery type. Adjusted Kaplan-Meier analysis was performed to determine the cumulative incidence of subsequent bladder outlet procedures by patient group, including group 1-age 60 years or greater and postoperative urinary retention, group 2-age 60 years or greater and no postoperative urinary retention, group 3-age less than 60 years and postoperative urinary retention, and group 4-age less than 60 years and no postoperative urinary retention. RESULTS Of 769,141 eligible male patients postoperative urinary retention developed in 8,051 (1.1%). Following hospital discharge 1,855 patients (0.24%) underwent a bladder outlet procedure. Those treated with a bladder outlet procedure were significantly more likely to have experienced postoperative urinary retention during the index admission (6.3% vs 1.0%, p <0.001). On matched analysis the bladder outlet procedure rate at 3 years was 7.1%, 2.2%, 0.8% and 0.0% in groups 1, 2, 3 and 4, respectively. CONCLUSIONS In men 60 years old or older postoperative urinary retention identified those with an increased incidence of bladder outlet procedures within 3 years. Men younger than 60 years had a low rate of subsequent bladder outlet procedures regardless of a postoperative urinary retention diagnosis.

Abstract
Cancer is a multifactorial disease, and imbalances of the immune response and sex-associated features are considered risk factors for certain types of cancer. The present study aimed to assess whether ankylosing spondylitis (AS), an immune disorder that predominantly affects young adult men, is associated with an increased risk of cancer. Using the Taiwan National Health Insurance Research Database, a cohort of patients diagnosed with AS between 2000 and 2008 who had no history of cancer prior to enrollment was established (n=5,452). Age- and sex-matched patients without AS served as controls (n=21,808). The results revealed that the overall incidence of cancer was elevated in patients with AS [standardized incidence ratio (SIR), 1.15; 95% confidence interval (CI), 1.03-1.27]. AS carried an increased risk of hematological malignancy in both sexes, colon cancer in females and bone and prostate cancer in males. Young patients with AS (≤35 years) and patients with a Charlson comorbidity index (CCI) ≥2 experienced a higher incidence of cancer (males, SIR 1.92, and 95% CI 1.04-3.26; females, SIR 2.00 and 95% CI 1.46-5.50). The cancer risk was increased during the first 3 years following the diagnosis of AS (SIR 1.49, 95% CI 1.29-1.71), and overall cancer-free survival was significantly decreased in patients with AS patients of both sexes (P<0.0001). Therefore, AS was found to be associated with an increased risk of cancer. All AS patients must be screened for hematological malignancies, for prostate and bone cancer in males, and for colon cancer in females, particularly younger patients with a CCI ≥2.

An Open-label, Single-dose, Pharmacokinetic Study of Factor VIII Activity After Administration of Moroctocog Alfa (AF-CC) in Male Chinese Patients With Hemophilia A. Clin Ther 2017; 39:1313-1319. [PMID: 28601434 DOI: 10.1016/j.clinthera.2017.05.344] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2016] [Revised: 04/27/2017] [Accepted: 05/11/2017] [Indexed: 11/16/2022]
Abstract
PURPOSE Hemophilia A represents up to 80% of all hemophilia cases in China. In patients with this condition, bleeding can be prevented and controlled by administering clotting factor VIII (FVIII). Since their initial availability, recombinant FVIII products have undergone several iterations to enhance their safety. Moroctocog alfa albumin-free cell culture (AF-CC) is among the third generation of recombinant FVIII products and received regulatory approval in China in August 2012. The present study characterizes the single-dose pharmacokinetic parameters of FVIII activity (FVIII:C) after administration of moroctocog alfa (AF-CC) in male Chinese patients with hemophilia A. METHODS This multicenter, open-label, single-dose study enrolled 13 male Chinese patients diagnosed with severe hemophilia A (FVIII:C <1%) and a history of at least 150 exposure-days to any FVIII-containing product. Eligible patients received a single dose of moroctocog alfa (AF-CC) 50 IU/kg IV within 10 minutes. Blood samples were collected within 2 hours before administration and through 72 hours after dosing. FINDINGS Pharmacokinetic parameters were assessed based on FVIII:C and were analyzed by age groups: ages 6 to <12 years (n = 3) and ≥12 years (n = 10). The mean plasma concentration-time profile for FVIII:C activity was consistently lower in patients aged 6 to <12 years compared with those aged ≥12 years. Geometric AUC0-∞ and Cmax were approximately 57% and 28% lower in the younger patients relative to the older patients, respectively. A total of 4 adverse events occurred in 4 patients. Low-titer, transient FVIII inhibitors were observed in 2 patients and were considered serious adverse events. Neither case resulted in clinical manifestations nor required treatment. IMPLICATIONS This is the first report of the pharmacokinetic parameters of FVIII:C after moroctocog alfa (AF-CC) in an all-Chinese population of males with hemophilia A. The pharmacokinetic profile in older patients was similar to that previously reported with recombinant FVIII products in studies with a predominantly white population; younger patients had reduced exposure to FVIII:C. The single doses of moroctocog alfa (AF-CC) were well tolerated; 2 cases of transient, low-titer FVIII inhibitor development were observed. ClinicalTrials.gov identifier: NCT02461992.

Abstract
Objectives In many African countries, child mortality is higher in the rainy season than in the dry season. We investigated the effect of season on child mortality by time periods, sex and age in rural Guinea‐Bissau. Methods Bandim health project follows children under‐five in a health and demographic surveillance system in rural Guinea‐Bissau. We compared the mortality in the rainy season (June to November) between 1990 and 2013 with the mortality in the dry season (December to May) in Cox proportional hazards models providing rainy vs. dry season mortality rate ratios (r/d‐mrr). Seasonal effects were estimated in strata defined by time periods with different frequency of vaccination campaigns, sex and age (<1 month, 1–11 months, 12–59 months). Verbal autopsies were interpreted using InterVa‐4 software. Results From 1990 to 2013, overall mortality was declined by almost two‐thirds among 81 292 children (10 588 deaths). Mortality was 51% (95% ci: 45–58%) higher in the rainy season than in the dry season throughout the study period. The seasonal difference increased significantly with age, the r/d‐mrr being 0.94 (0.86–1.03) among neonates, 1.57 (1.46–1.69) in post‐neonatal infants and 1.83 (1.72–1.95) in under‐five children (P for same effect <0.001). According to the InterVa, malaria deaths were the main reason for the seasonal mortality difference, causing 50% of all deaths in the rainy season, but only if the InterVa included season of death, making the argument self‐confirmatory. Conclusion The mortality declined throughout the study, yet rainy season continued to be associated with 51% higher overall mortality.

Abstract
Patients with vaginitis were classified into four groups: Group A (prepubertal under-aged females); Group B (pubertal under-aged females); Group C (reproductive age adult females); Group D (postmenopausal adult females). All vaginal specimens underwent microscopy, amine testing, Gram staining and culturing. Overall, 163 patients were included (33, 14, 81 and 35 patients, respectively). The most common infection was bacterial vaginosis (BV), followed by Ureaplasma infection, aerobic vaginitis (AV) and candidiasis. The most common AV-associated organism was Escherichia coli and the most common BV-associated organism was Gardnerella vaginalis. AV was more frequent in Group A, BV in Group C and Ureaplasma infections in Groups C/D. Decreased lactobacilli concentrations were associated with BV in fertile patients (Groups B-C). Although presentation of vaginitis is similar among females of different age in Greece, type and prevalence of pathogens differ. Normal vaginal flora changes are associated with higher risk of vaginitis in specific age groups. Impact Statement The worldwide incidence of reproductive tract infections has been increasing, with specific pathogens being associated with significant risk of morbidity and complications. However, literature data on the distribution of such infections in different age groups is limited. Therefore, the aim of this study was to provide data on the prevalence and causes of vaginitis in adult and non-adult females of all ages. This study has shown that although presentation of vaginitis is similar among females of different age groups and menstrual status in Greece, type and prevalence of responsible pathogens are different among groups. Changes in normal vaginal flora seem to be associated with higher risk of vaginitis in specific age-groups as well. These findings could contribute in adjusting diagnostic and therapeutic strategies for each age group according to the prevailing pathogens. Further research on antibiotic resistance and treatment outcomes for each age group should be conducted.

Gerontol Geriatr Med 2017; 3:2333721417706299. [PMID: 28516129 PMCID: PMC5419065 DOI: 10.1177/2333721417706299] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2016] [Revised: 03/22/2017] [Accepted: 03/27/2017] [Indexed: 12/17/2022] Open
Abstract
Aim: Enhanced recovery after surgery (ERAS) is a multimodal approach that aims to optimize perioperative treatment. Whether elderly patients receiving colorectal surgery can adhere to and benefit from an ERAS approach is uncertain. The aim of this study was to compare patients in different age groups participating in an ERAS program. Method: In this substudy of a randomized controlled trial, we analyzed the interventional ERAS arm of adult patients eligible for laparoscopic or open colorectal resection with regard to the importance of age. Patients were divided into three groups based on age: ≤65 years (n = 79), 66-79 years (n = 56), and ≥80 years (n = 19). The primary end point was total postoperative hospital stay (THS). Secondary end points were postoperative hospital stay, postoperative complications, postoperative C-reactive protein levels, readmission rate, mortality, and patient adherence to the different ERAS elements. All parameters and measuring the adherence to the ERAS protocol were recorded before surgery, on the day of the operation, and daily until discharge. Results: There were no significant differences in length of THS between age groups (≤65 years, median 5 [range 2-47] days; 66-79 years, median 5.5 [range 2-36] days; ≥80 years, median 7 [range 3-50] days; p = .53). All secondary outcomes were similar between age groups. Patient adherence to the ERAS protocol was as good in the elderly as it was in the younger patients. Conclusion: Elderly patients adhered to and benefited from an ERAS program, similar to their younger counterparts.

Abstract
Objectives: This study was conducted to determine incidence trends of female breast cancer according to age groups and to predict future change in Chiang Mai women through 2028. Method: Data were collected from all hospitals in Chiang Mai in northern Thailand, from 1989 through 2013, and used to investigate effects of age, year of diagnosis (period) and year of birth (cohort) on female breast cancer incidences using an age-period-cohort model. This model features geometric cut trends to predict change by young (<40 years), middle-aged (40-59) and elderly (≥60) age groups. Result: Of 5, 417 female breast cancer patients with a median age of 50 years (interquartile range: 43 to 59 years), 15%, 61% and 24% were young, middle-aged and elderly, respectively. Seventy nine percent of cancer cases in this study were detected at advanced stage. The trend in stage classification showed an increase in percentage of early stage and a decrease in metastatic cancers. Linear trends for cohort and period were not found in young females but were observed in middle-aged and elderly groups. Age-standardized rates (ASR) can be expected to remain stable around 6.8 per 100,000 women-years in young females. In the other age groups, the ASR trends were calculated to increase and reach peaks in 2024 of 120.2 and 138.2 per 100,000 women-years, respectively. Conclusion: Cohort effects or generation-specific effects, such as life style factors and the year of diagnosis (period) might have impacted on increased incidence in women aged over 40 years but not those under 40 years. A budget should be provided for treatment facilities and strategies to detect early stage cancers. The cost effectiveness of screening measures i.e. mammographic screening may need to be reconsidered for women age over 40 years.

Abstract
OBJECTIVE The objective of this research is to study depressive symptoms (DS) among adults aged 40 to 79 years and examine how mastery influences the impact of sociodemographic, socioeconomic, and health factors on DS. METHOD We used a sample of the Norwegian Life Course, Generation, and Gender (LOGG) study ( N = 6,879) and analyzed how mastery influences the independent variables on DS via regression analyses. RESULTS Mastery affected DS directly and influenced the effects of sociodemographic, socioeconomic, and health factors on DS. There was a stronger relationship between stressors and DS among respondents with low than high mastery. DS were most prevalent among people aged 70 to 79 years. When mastery was also controlled for, the oldest group (70-79 years) had significantly fewer DS than those aged 40 to 49 years. DISCUSSION The influence of mastery and stressors on DS seems to vary along the life span. The result that mastery was a relatively stronger buffer against DS in midlife than in old age is discussed.

Abstract
PURPOSE Although testosterone replacement therapy use in the United States has increased dramatically in the last decade, to our knowledge trends in testosterone replacement therapy use among reproductive-age men have not been investigated. We assessed changes in testosterone replacement therapy use and practice patterns among 18 to 45-year-old American men from 2003 to 2013 and compared them to older men. MATERIALS AND METHODS This is a retrospective, cross-sectional analysis of men 18 to 45 and 56 to 64 years old who were enrolled in the Truven Health MarketScan® Commercial Claims Databases throughout each given calendar year from 2003 to 2013, including 5,094,868 men in 2013. Trends in the yearly rates of testosterone replacement therapy use were calculated using Poisson regression. Among testosterone replacement therapy users, the Cochran-Armitage test was used to assess temporal trends in age, formulation type, semen analysis and serum testosterone level testing during the 12 months preceding the documented use of testosterone replacement therapy. RESULTS Between 2003 and 2013, there was a fourfold increase in the rate of testosterone use among 18 to 45-year-old men from 29.2/10,000 person-years to 118.1/10,000 person-years (p <0.0001). Among testosterone replacement therapy users, topical gel formulations were initially most used. Injection use then doubled between 2009 and 2012 (23.5% and 46.2%, respectively) and surpassed topical gel use in 2013. In men 56 to 64 years old there was a statistically significant threefold increase in testosterone replacement therapy use (p <0.0001), which was significantly smaller than the fourfold increase in younger men (p <0.0001). CONCLUSIONS In 2003 to 2013, testosterone replacement therapy use increased fourfold in men 18 to 45 years old compared to threefold in older men. This younger age group should be a focus for future studies due to effects on fertility and unknown long-term sequelae.

Abstract
BACKGROUND The present contribution deals with theoretical aspects regarding biogenic particle clearance from various lung structures of probands with different ages (1, 5, 15, 20 y). With reference to part 1 of the study, particles varying in size and shape are subject to a detailed analysis. The main goal of the investigation consists in an increase of our knowledge concerning the clearance behaviour of bioparticles and its dependence upon various physiological and anatomical factors. METHODS Theoretical clearance of biogenic particles was subdivided into four main phases, namely fast bronchial clearance, slow bronchial clearance, fast alveolar clearance, and slow alveolar clearance. All of these phases were simulated by using a well validated stochastic modeling approach, where the main focus is set on the randomly varied particle mass transfer between main compartments of the human respiratory tract. Whilst effects of particle geometry on clearance were approximated by application of the projective-diameter concept, age dependence of the particle removal process was expressed by the experimentally proven relationship between bronchial mucus velocities and morphometry of the airway tree. RESULTS According to the results of the theoretical simulations efficiency of fast bronchial clearance, expressed by the 24-h-retention value, exhibits a negative correlation with proband's age, whereas the other clearance phases are characterized by a rather conservative behaviour among the different age categories. Highest clearance rates may be observed for very fine (<0.01 µm) and very coarse particles (>5 µm) preferentially deposited in the upper bronchial airways, whilst large particles accumulated in the alveoli may be stored there for several months to years. CONCLUSIONS The study comes to the conclusion that infants and children dispose of an enhanced bronchial clearance efficiency with respect to adolescents and adults, which results in a faster removal of particulate substances accumulated in the upper bronchial regions. Particles escaping from the natural filtering process in the upper airways and undergoing alveolar deposition are subject to identical clearance scenarios among the age groups and may represent remarkable health hazards.

Abstract
Essentials The EU-PACT trial was used to investigate age on the interaction between coumarins and genotype. The results support the use of genotype-guided dosing for phenprocoumon in patients < 75 years. For patients ≥ 75 years the phenprocoumon algorithm should be revised and further tested. No influence of comorbidities and co-current drug use was found that could explain the differences. SUMMARY Background Age seemed to affect the interaction between coumarins and genotype in the acenocoumarol and phenprocoumon arm of the European Pharmacogenetics of Anticoagulant Therapy (EU-PACT) trial. Objectives To investigate the effect of genotype-guided dosing stratified by age and the potential factors causing a difference. Patients/Methods Data from the acenocoumarol/phenprocoumon arm of the EU-PACT trial were used. The percentages of time below the therapeutic range, time above the therapeutic range and time in the therapeutic range (TTR) during the initial 12 weeks of therapy were compared between the genotype-guided group and the control group among younger (< 75 years) and older (≥ 75 years) patients by the use of independent t-tests, and adjusted for sex, height, weight and co-medications by the use of linear regression. Results Among younger phenprocoumon users, TTR during the first 12 weeks in the genotype-guided group (n = 55) was 9.5% (95% confidence interval [CI] 1.3 to 17.8) higher than in the control group (n = 63), with a remarkably lower percentage of time above this range (difference: - 9.6%, 95% CI - 19.0 to - 0.2) and a similar time below this range. Older patients dosed by the genotype-guided algorithm (n = 24) spent more time above the range (difference: 27.5%, 95% CI 12.9 to 42.0). For acenocoumarol users, there were no significant differences between the genotype-guided and control groups for most outcomes, except for a lower percentage of time below the range among older patients. Conclusions The genotype-guided algorithm for phenprocoumon in the EU-PACT trial benefitted younger patients more, but for older patients the algorithm needs to be revised and tested in further research.

Abstract
OBJECTIVES This was a comparative study between Australia and Korea that investigated whether and to what extent factors related to self-rated good health (SRGH) differ by gender among age groups. METHODS This study was a secondary analysis of data that were collected in nationally representative, cross-sectional, and population-based surveys. We analyzed Australian and Korean participants > 20 years of age using 2011 data from the Australian National Nutritional Physical Activity Survey (n = 9,276) and the Korean National Health and Nutritional Examination Survey (n = 5,915). Analyses were based on multiple logistic regression after controlling for covariates. RESULTS Factors associated with SRGH and the extent of their influence differed by gender among age groups within each nation. Australian SRGH was associated with more factors than Korean SRGH, except in participants > 65 years old. Many differences among adults aged 20-44 years were observed, particularly with regard to the influence of socioeconomic factors. Living with a spouse only influenced SRGH in men 20-44 years old in both countries, negatively for Korean men and positively for Australian men. In this same age group, SRGH was positively influenced by employment and attainment of a higher education level in Australian men but not among Korean men; among women, income, but not education, affected SRGH in Korea, whereas in Australia, women were more influenced by education than by income. Lack of chronic disease had a strong influence on SRGH in both countries and was influential in all Australians and Koreans except those ≥ 65 years old. CONCLUSION Broad features of society should be considered when discussing health and differences in associated factors and their influences. For focused public health interventions of population groups, it is also necessary to consider gender and age groups within social environments.

Abstract
PURPOSE We sought to determine whether frailty affects the type of pelvic organ prolapse surgery performed and the odds of postoperative complications. MATERIALS AND METHODS This is a retrospective cohort study of women who underwent obliterative and reconstructive surgery for pelvic organ prolapse in ACS (American College of Surgeons) NSQIP® (National Surgical Quality Improvement Program) from 2005 to 2013. We quantified frailty using NSQIP-FI (Frailty Index) and applied logistic regression models predicting the type of procedure (colpocleisis) and the odds of postoperative complications. RESULTS We identified a total of 12,731 women treated with pelvic organ prolapse repair, of which 5.3% were colpocleisis procedures, from 2005 to 2013. Among women undergoing colpocleisis, the average age was 79.2 years and 28.5% had a NSQIP-FI of 0.18 or higher, indicating frailty. Women undergoing colpocleisis procedures had higher odds of being frail (NSQIP-FI 0.18 vs 0 OR 1.9, 95% CI 1.4-2.6) and were older (age 85+ vs less than 65 years OR 486.4, 95% CI 274.6-861.7). For all types of pelvic organ prolapse procedures, frailty increased the odds of complications (NSQIP-FI 0.18 vs 0 OR 2.8, 95% CI 1.8-3.0), after adjusting for age and type of pelvic organ prolapse procedure. CONCLUSIONS For pelvic organ prolapse surgery, age rather than frailty is more strongly associated with the type of procedure performed. However, frailty is more strongly associated with postoperative complications than age. Furthermore, incorporating frailty into preoperative decision making is important to improve expectations and outcomes among older women considering pelvic organ prolapse surgery.

Abstract
AIMS With self-reporting of erectile dysfunction (ED) in population-based surveys, men with ED may not represent men who are bothered sufficiently to seek an ED diagnosis and treatment. We used real-world observational data to assess: 1) the prevalence of ED diagnosis or treatment by age subgroups; and 2) the relationship of age with ED diagnosis or treatment after controlling for ED-related comorbidities in the USA. METHODS This cross-sectional study used de-identified claims data (MarketScan® databases; primary analysis). Sensitivity analysis was conducted using electronic health records (Humedica® database). Inclusion criteria were men aged ≥18 years with a 360-day continuous enrollment before the index date. We assessed the prevalence of ED diagnosis or phosphodiesterase type 5 inhibitor (PDE5I) prescription by age and the risk for ED diagnosis or treatment by age after controlling for comorbidities (hypertension, other cardiovascular disease, diabetes mellitus, depression and benign prostatic hyperplasia). RESULTS Of 19,833,939 men meeting inclusion criteria in the primary analysis, only 1 108 842 (5.6%) had an ED diagnosis or PDE5I prescription (mean [SD] age: 55.2 [11.2] years). Prevalence of ED diagnosis or treatment increased from age 18-29 years (0.4%) to 60-69 years (11.5%), then decreased in the seventh (11.0%), eighth (4.6%), and ninth (0.9%) decades. Men with ED diagnosis or treatment had a higher prevalence of any comorbidity (63.1% vs 29.3% for men without ED) and of each comorbid condition. In multivariate analyses, age was an independent risk factor for ED diagnosis or treatment. Sensitivity analysis provided consistent results. CONCLUSIONS In a real-world setting in the USA, the prevalence of ED diagnosis or PDE5I treatment is generally low, increases with age, decreases in very old men, and is associated with increased prevalence of comorbidities. Age is an independent risk factor for ED diagnosis or treatment after controlling for comorbidities.

Abstract
INTRODUCTION Body mass index and physical fitness are important markers of a healthy life style. Objective: To analyze adiposity and physical fitness in young students from public schools in Armenia, Colombia, and examine differences between sex and age groups. Materials and methods: We analyzed 1,150 students: 46.6% (n=536) males and 53.4% (n=614) females, with an age range of 10 to 20 years (15.45 ± 2.52). Physical fitness was evaluated by the Course-Navette test, the Horizontal Jump test, the 20-meter run test and the Sit-and-Reach test. Body mass index and body fat were also assessed. Results: Compared with males, females had significantly higher adiposity levels, body mass index (20.4 vs. 19.5) and body fat (23% vs. 11%). Males had higher levels of physical fitness in all the variables analyzed, with statistically significant differences (p<0.001), except in flexibility, where females achieved better results (3.1cm vs.1 3cm; p=0.003). In both sexes, body mass index increased with age (p<0.001). However, body fat decreased with age in males (p<0.001) and increased in females (p<0.001). In males, physical fitness improved with age in all variables. In females, no significant differences were found between age groups except in the maximal oxygen uptake (VO2max, p<0.001). Conclusion: Adiposity was significantly higher in women than in men. Males had a better level of physical fitness than females, except in flexibility. Physical fitness improved significantly with age in males, but did not change in females.

Abstract
Botulism had mortality rates >60% before the 1950s. We reviewed confirmed botulism cases in the USA during 1975-2009 including infant, foodborne, wound, and other/unknown acquisition categories, and calculated mortality ratios. We created a multivariate logistic regression model for non-infant cases (foodborne, wound, and other/unknown). Overall mortality was 3.0% with 109 botulism-related deaths among 3,618 botulism cases [18 (<1%) deaths among 2,352 infant botulism cases, 61 (7.1%) deaths among 854 foodborne botulism cases, 18 (5.0%) deaths among 359 wound botulism cases, and 12 (22.6%) deaths among 53 other/unknown botulism cases]. Mortality among all cases increased with age; it was lowest among infants (0.8%) and highest among persons ≥80 years old (34.4%). Toxin type F had higher mortality (13.8%) than types A, B, or E (range, 1.4% to 4.1%). Efforts to reduce botulism mortality should target non-infant transmission categories and older adults.

Abstract
BACKGROUND In this contribution the inhalation and deposition of bioaerosols including particles with various shapes and sizes were investigated for probands with different ages (1, 5, 15 and 20 y). The study should help to increase our knowledge with regard to the behavior of variably shaped and sized particles in lungs being subject to different developmental stages. METHODS Simulation of particle transport and deposition in single structures of the respiratory tract was conducted by using a stochastic model of the tracheobronchial tree and well-validated analytical and empirical deposition formulae. Possible effects of particle geometry on deposition were taken into consideration by application of the aerodynamic diameter concept. Age-dependent lung morphometry and breathing parameters were computed by using appropriate scaling factors. RESULTS Theoretical simulations came to the result that bioparticle deposition in infants and children clearly differs from that in adolescents and adults insofar as the amount of deposited mass exhibits a positive correlation with age. Nose breathing results in higher extrathoracic deposition rates than mouth breathing and, as a consequence of that, lower particle amounts are enabled to enter the lung structures after passing the nasal airways. Under sitting breathing conditions highest alveolar deposition rates were calculated for particles adopting aerodynamic diameters of 10 nm and 4 µm, respectively. CONCLUSIONS The study comes to the conclusion that bioparticles have a lower chance to reach the alveoli in infants' and children's lungs, but show a higher alveolar deposition probability in the lungs of adolescents and adults. Despite of this circumstance also young subjects may increasingly suffer from biogenic particle burden, when they are subject to a long-term exposure to certain bioaerosols.

Abstract
BACKGROUND Pediatric drug development is plagued by small sample sizes, unvalidated clinical endpoints, and limited studies. OBJECTIVES The objective of this study was to determine whether age stratification within the pediatric population could be used to (1) assess response to a pharmacologic intervention and to (2) design future trials based upon published stratified disease data using clinical trial simulation (CTS). METHODS Data available from the literature for Kawasaki disease (KD) was used in the model. Age-stratified CTS for a theoretical new drug was conducted. RESULTS Population-specific differences due to age might affect trial success if not taken into account. CTS predicted inflammatory indices, and inclusion cutoff significantly altered the trial outcome. Finally, altered pharmacokinetics/pharmacodynamics in varying age groups of KD patients may alter drug exposure and response. CONCLUSIONS If assumptions regarding a pediatric disease process, such as KD, do not include age stratification with inclusion or response, then the wrong decision could result with regard to age-appropriateness or approval of a drug.

Abstract
OBJECTIVE Acute diverticulitis has been traditionally associated with worse outcome in young patients, indicating a more aggressive surgical approach is required for them. The aim of this study was to assess whether acute diverticulitis was more virulent in young patients. METHODS A retrospective, cross-sectional study included all patients who were admitted for a first episode of acute diverticulitis between January 2004 and December 2013. The patients were divided into two groups (≤50 years and >50 years) based on their age. Patients' characteristics, clinical and surgical data were recorded and analyzed. RESULTS Overall, 636 patients were included in the database, including 177 (27.8%) in the younger group and 459 in the elder group. There were no significant differences between the groups in disease complexity, peritonitis, laboratory work-up, vital signs on presentation, bowel obstruction or the presence of fistula and abscess in need of drainage. Younger patients had more free extra-luminal air on computed tomography (CT) scan (P = 0.03). Surgical data, including the intra-operative modified Hinchey score and the need for emergency and additional surgery did not significantly differ between the two groups. Young patients had more readmissions (P = 0.01) due to acute diverticulitis, diverticular complications and elective surgery. Length of hospital stay (P = 0.0001) was longer and postoperative complications were more common in the elder patients. CONCLUSIONS The clinical presentation of acute diverticulitis does not seem to be worse in the young population. Younger patients tend to have a more severe presentation on CT scan and more readmissions, but this did not translate to a more severe disease course.

Abstract
BACKGROUND The incidence and prevalence of urinary stone are increasing throughout the world. Compared to the past, recent demographics of patient with urolithiasis compositions are strikingly different. Furthermore, recent clinical studies implied that seasonal cyclicity might influence the distribution of stone composition. METHODS We sought to determine the trends in pathogenesis of urolithiasis based on urinary stone analyses. Between 2002 and 2014, a total of 2,383 eligible urinary stone samples from different patients were collected in our center. Infrared spectroscopy was used for urinary calculi analysis. A logistic regression analysis was used to investigate the relationship between urinary calculi composition and calendar month (season), gender, and age in north China during the past 13 years. RESULTS Calcium-containing calculi were the most frequent with an overall incidence of 84.1%. Calcium phosphate (CaP) or magnesium ammonium phosphate (MAP) stones were more frequent in females, while monohydrate calcium oxalate (COM), dihydrate calcium oxalate (COD), or uric acid (UA) stones were more common in males. Older individuals were associated with an increased risk of UA stones and a decreased risk of COD, CaP, or cystine stones. Additionally, from 2002 to 2014, the frequency of COD and MAP stone increased, whereas the trend of CaP, UA and cystine stones decreased. However, calendar month (season) was not significantly associated with differences in composition. CONCLUSION This study provides the present distribution of urolithiasis compositions in China. From 2002 to 2014, age and gender were significantly associated with stone composition, whereas calendar month was not.

Abstract
BACKGROUND Age and sex are important considerations in the choice between percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in daily clinical practice. METHODS AND RESULTS Of 25 816 patients enrolled in the multicenter Coronary Revascularization Demonstrating Outcome Study in Kyoto (CREDO-Kyoto; Cohort-1, n=9877; Cohort-2, n=15 939), the present study population consisted of 5651 patients (men, n=3998; women, n=1653) with triple-vessel coronary artery disease who were considered to be pertinent in comparisons of PCI with CABG (PCI, n=3165; CABG, n=2486). Patients were divided into 3 groups according to the tertiles of age: ≤65 years (n=1972), 66 to 73 years (n=1820), and ≥74 years (n=1859). The excess adjusted mortality risk of PCI relative to CABG was significant in patients ≥74 years of age (hazard ratio [HR], 1.40; 95% confidence interval [CI], 1.10-1.79; P=0.006), whereas the risks were neutral in patients ≤65 years of age (HR, 1.05; 95% CI, 0.73-1.53; P=0.78) and in patients 66 to 73 years of age (HR, 1.03; 95% CI, 0.78-1.36; P=0.85; interaction P=0.003). The excess mortality risk of PCI relative to CABG was significant in men (HR, 1.24; 95% CI, 1.03-1.50; P=0.02) and trended to be significant in women (HR, 1.34; 95% CI, 0.98-1.84; P=0.07) without significant interaction between sex and the mortality risk of PCI relative to CABG (interaction P=0.40). CONCLUSIONS There was a significant association between age and the mortality risk of PCI relative to CABG with excess risk in patients ≥74 years of age and neutral risk in younger patients. There was no significant sex-related difference in the mortality risk of PCI relative to CABG.

Abstract
Single and continuous vertical jumping tests, as well as the Wingate anaerobic test (WAnT), are commonly used to assess the short-term muscle power of female volleyball players; however, the relationship among these tests has not been studied adequately. Thus, the aim of the present study was to examine the relationship of single and continuous vertical jumps with the WAnT in female volleyball players. Seventy adolescent (age 16.0 ± 1.0 years, body mass 62.5 ± 7.1 kg, height 170.4 ± 6.1 cm, body fat 24.2% ± 4.3%) and 108 adult female volleyball players (age 24.8 ± 5.2 years, body mass 66.5 ± 8.7 kg, height 173.2 ± 7.4 cm, body fat 22.0% ± 5.1%) performed the squat jump (SJ), countermovement jump (CMJ), Abalakov jump (AJ), 30 s Bosco test and WAnT (peak power, Ppeak; mean power, Pmean). Mean power in the Bosco test was correlated (low to large magnitude) with Pmean of the WAnT (r = 0.27, p = 0.030 in adolescents versusr = 0.56, p < 0.001 in adults). SJ, CMJ and AJ also correlated with Ppeak (0.28 ≤ r ≤ 0.46 in adolescents versus 0.58 ≤ r ≤ 0.61 in adults) and with Pmean (0.43 ≤ r ≤ 0.51 versus 0.67 ≤ r ≤ 0.71, respectively) of the WAnT (p < 0.05). In summary, the impact of the Bosco test and WAnT on muscle power varied, especially in the younger age group. Single jumping tests had larger correlations with WAnT in adults than in adolescent volleyball players. These findings should be taken into account by volleyball coaches and fitness trainers during the assessment of short-term muscle power of their athletes.

Abstract
Bariatric surgery has become an accepted method to treat obesity and its related diseases in adults; nevertheless, few bariatric surgery follow-up studies compare changes in body mass index (BMI), disease outcomes, and side effects among age groups. This study compares bariatric surgery outcomes across four adult age groups by comparing changes in milestone BMIs such as highest and lowest BMI, perceived existing disease outcomes, and symptoms related to those diseases. Data were obtained using a 40-item questionnaire that was mailed to 2,520 patients of a Midwestern weight management center who were at least 18 months post-bariatric surgical procedure. The 534 respondents were divided into four age groups in years: 18 to 49 (n = 171), 50-59 (n = 148), 60-69 (n = 138), and ≥ 70 (n = 77). There were no differences among the age groups for lowest (p = .93) and current BMI (p = .51). Significant improvement in eight chronic diseases occurred across all age groups. There were no differences between age groups in reported occurrence of incontinence (p = .65), diarrhea (p = .22), flatulence (p = .46), heartburn (p = .73), and indigestion (p = .22). Constipation rarely occurred among the oldest adults (p < .001). Bariatric surgery should be considered an option for weight loss and disease management for older adults as much as it is for younger adults.

Alanine aminotransferase and gamma-glutamyl transferase have different dose-response relationships with risk of mortality by age. Liver Int 2016; 36:126-35.

Abstract
BACKGROUND & AIMS It remains unclear whether the respective dose-response relationships between serum alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT) levels and risk of mortality are consistent by age. METHODS We used sampled cohort data from the National Health Insurance Corporation to conduct a retrospective cohort study. A total of 313 252 participants who received medical health check-ups from 2002 to 2008 were assessed for risk of death according to serum ALT and GGT levels over an average of 6 years. The hazard ratios (HRs) for mortality were analysed with Cox proportional hazard model. RESULTS The crude mortality rate increased linearly with increasing serum ALT and GGT levels in adults aged <60 years. However, the all-cause mortality rate showed a J-shaped relationship with increasing serum ALT levels whereas all-cause mortality rate showed a linear relationship with increasing serum GGT levels in adults aged ≥60 years. The HR of death showed U-shaped relationships with increasing serum ALT levels in adults aged ≥60 years. On the contrary, the HR of death from any cause had a linear association with increasing serum GGT levels among all age groups. CONCLUSIONS In this study, U-shaped relationship patterns were demonstrated between serum ALT levels and risk for all-cause mortality in adults aged ≥60 years while serum GGT levels showed a linear relationship with risk for all-cause death. Very low levels of serum ALT in elderly patients suggest that they are at high risk of mortality.
