Correlation of time trends of air pollutants, greenspaces and tracheal, bronchus and lung cancer incidence and mortality among the adults in United States.

Background: Tracheal, Bronchus, and Lung (TBL) cancer continues to represent the majority of cancer-related incidence and mortality in United States (U.S.). While air pollutants are considered essential risk factors, both global and national average concentrations of major harmful air pollutants have significantly decreased over the decades. Green space may have a beneficial effect on human health. Methods: We obtained data on national and state-level burden of TBL cancer, the annual average concentration of main air pollutants, and levels of green spaces in 2007, 2013, and 2019. According to generalized estimating equation (GEE), we examine the associations among incidence and mortality of TBL cancer, air pollutants, and greenspaces, represented by the Normalized Difference Vegetation Index (NDVI) in different age groups with models adjusted with meteorological, and socio-demographic. We observed additional effects of the interaction between the NDVI, Ozone, PM2.5, and other factors, which helped us to interpret and understand our results. Also, we collated states that witnessed net increments in forest coverage and conducted the same analysis separately. Results: In our analysis, the majority of associations between NDVI and air pollutants with TBL cancer remained significantly positive, particularly noticeable among individuals aged 20 to 54. However, our findings did not explore air pollution as a potential mediator between greenspace exposure and TBL cancer. While the associations of PM2.5 with TBL cancer remained positive, the other four pollutants showed positive but statistically insignificant associations. Our interaction analysis yielded that there were positive associations between NDVI and ozone, PM2.5, and tobacco use. Max NDVI acts as a protective factor along with high HDI. Additionally, PM2.5 and HDI also showed a negative association. In 18 states with more forest, NDVI acts as a protective factor along with higher health care coverage, better health status, and participation in physical activities. Conclusion: In the state-level of U.S., the effects of total greenspace with TBL cancer are mixed and could be modified by various socio-economic factors. PM2.5 has a direct correlation with TBL cancer and the effects can be influenced by underlying socioeconomic conditions.

[Comparative assessment of the intensity of caries among dental patients of older age groups in need of removable prosthetics, registered by a phthisiatician and their perception of an artificial ageist situation.]

Improving the quality of life of older age groups is an urgent problem of medicine, including its components: gerontology, phthisiology and dentistry. The objectives of the study are: to establish the importance of tuberculosis as an infection that causes the intensity of caries among patients of older age groups; assessment using the Palmore scale of gerontological ageism «The ageism survey¼ and patients' perception of an artificial situation of age inequality. The study involved elderly (n=122) and senile (n=121) persons with partial secondary adentia who needed removable dentures. The control groups of older people included patients who denied being under the supervision of a phthisiologist, and the study groups confirmed this. To solve the first problem, a comparative assessment of the values of the components of the CPI index in the control and study groups was carried out. To solve the second problem, an artificial situation of age inequality was simulated in the process of dental admission. The results of its effects were evaluated based on the response of patients to questions № 9, 10 of the Palmor scale. The absence of a difference in the values of K and N components between the control and study groups indicates the absence of a significant effect of mycobacteria on the development of caries. The large values of component Y in the studied groups may indicate the detrimental effect of mycobacteria on periodontal disease. The absence of an increase in the intensity and stability of the perception of age inequality among patients who are under the influence of an artificially created situation proves the great effectiveness of background age inequality. At the same time, it is impossible to exclude the low sensitivity of the Palmor scale in the process of diagnosing age inequality in Russian society.

[The analysis of age dynamics of causes of mortality of population of elderly age groups as reserve of maintaining population of older able-bodied age].

The article analyzes age dynamics of initial causes of death according to records in medical death certificates of population of older age groups. Materials and methods. The records of causes of death of 34.914 persons aged 60 years and older were used as primary source of information. The initial cause of death was determined according to the ICD-10 rules. The rate of registration by reason of death was calculated as intensive value per 100 deaths in concrete age and sex group. Each cause was coded according to the ICD-10 rules (revision 2014-2016). The belonging to group was determined by first character (letter) in four-digit code that corresponded to the Class. On the basis of analysis of structure of causes of death, the group A of causes that included five Classes of ICD-10, determined 81.4% of all deaths in population aged 60 years and older. Two Classes: "Diseases of the circulatory system" (Class IX) and "Neoplasms" (Class II) determine in all studied age groups more than a half of all deaths (from 55% to 71% of males and from 59% to 67% in females) and namely they determine mortality rate in older age groups. There are no gender differences in age characteristics of registration rate in these groups (p > 0.05), however age dynamics differ. In case of diseases of circulatory system initial cause of death is increase rate of registration at increasing of age. In case of neoplasms at increasing of age decrease of registration rate as initial cause of death is established. At that, rate of decline is higher than rate of increase that determines certain decrease of structural significance of combined contribution of these two groups of causes at increasing of age. The Group B of causes, including three Classes of ICD-10 "Respiratory diseases" (Class X), "Diseases of the digestive system" (Class XI) and "Diseases of the nervous system" (Class VI), determined in overall 11.9% of all deaths in population aged 60 years and older. The age dynamics of causes of death of population of older age groups exists for certain groups of causes and it should be considered in organizing medical care of population of older age groups.

Analyzivng Demand for Customized Obesity Prevention and Management Across Adult Age Groups Using Focus Group Interview.

With the increasing obesity rates, many studies on obesity prevention and management have been implemented. However, few studies focused on obesity in adulthood and different perceptions of obesity between life cycles. Thus, this study aimed to investigate the demand for customized obesity prevention and management (OPM) strategies across adult age groups. Focus group interviews were conducted to gather insights from three age groups: young adults (20-34 years), middle-aged adults (35-49 years), and seniors (50-64 years). A total of 17 participants took part in the study, with 5 participants in Group 1, 6 participants in Group 2, and 6 participants in Group 3. Thematic analysis and the use of NetMiner version 4.4.3 facilitated data categorization and scrutiny. The study employed qualitative methods to explore perceptions of obesity and preferences for personalized OPM strategies among participants. Diverse perspectives on obesity as a health threat were found among the age groups. While all stressed the importance of personalized OPM, preferences for strategies varied. Diet and exercise combination emerged as a common preference. This study highlighted the need for customized OPM approaches aligned with age-specific preferences.

Psychological capacity profiles of different age groups and gender in a national representative sample.

Beyond the specific cognitive capacities like numerical or verbal intelligence and cognitive speed, the so-called soft skills, namely, psychological capacities, have become highly important in modern life. This is the first representative study on the distribution of work-relevant psychological capacities in the general population. We investigate capacities in different age groups, gender, and their relation with basic sociodemographics. A representative sample of 2531 people aged 14-95 years was investigated concerning work-relevant psychological capacities with the mini self-rating for psychological activities and participation (Mini-ICF-APP-S). The strongest capacities in young people were mobility, flexibility, proactivity, contact to thirds, and group interaction. Other capacities were stronger in midlife (30-59 years), such as adjustment to rules and routines, planning and structuring, decision making and judgement, application of competence and knowledge, assertiveness, dyadic relationships, endurance, and self-care. Women reported better dyadic relationship capacities, and men felt more assertive. The study provides, for the first time, representative data on a broad range of psychological capacities according to an internationally validated capacity concept. Good psychological capacities occur not primarily in youth, but especially in midlife and older age. Regarding demographic change, this implies older people are highly competent in the working world.

Gonial Angle in Forensic Anthropology to Determine Age and Gender: A Population-Specific Analysis.

Background The study highlights the gonial angle as a key craniofacial landmark for age and gender determination in forensic cases. It emphasizes population-specific analysis, enhancing precision by recognizing variations between populations. By clarifying the gonial angle's forensic use, the study offers clear guidelines, improving forensic practices. Moreover, the gonial angle and age and gender correlations are thoroughly examined, offering important information on their forensic relevance. The results highlight how crucial population-specific research is to improving the precision and dependability of forensic age and gender estimation techniques, which advances forensic anthropology and supports forensic investigations around the globe. Aim and objective The purpose of this study is to assess the accuracy of age and gender estimates using gonial angles. The objectives of this research are to evaluate the precision of age and gender estimates utilizing the gonial angle. Materials and methods This present study comprises two groups based on age groups: Group I belongs to 51 to 60 years of age, and Group II belongs to 61 to 70 years of age. Making use of G-Power software (version 3.1.9.4, Düsseldorf, Germany), the sample size was determined. The calculation ensured 95% statistical power at a significance level (alpha error probability) of 0.05. To achieve sufficient statistical power, a total of 1000 samples were included, with a projected required sample size of 92. A total of 1000 samples, consisting of 500 male and 500 female panoramic radiographs, were meticulously selected for the study. The samples picked were within the age range of 51 to 70 years. Orthopantomograms were determined using Planmeca software (Planmeca Romexis®, Version 6.0, USA Inc.). Descriptive statistics, including prediction classification analysis of age and gender, were conducted using SPSS Statistics version 16.0 (SPSS Inc., Released 2007, SPSS for Windows, Version 16.0, Chicago, SPSS Inc.). Results According to this study, the mean gonial angle of males aged 51 to 60 years is larger (124.7370 degrees) than that of females (119.6371 degrees). The female group's mean estimates are more accurate, as seen by the smaller standard error (0.20844) compared to the male group's (0.60998). A statistically significant difference in mean gonial angles between the genders is evident, with males having a larger gonial angle (p-value <0.001). In the age range of 61 to 70 years, the mean gonial angle of females is higher (128.4322 degrees) than that of males (124.0529 degrees). In this instance, the male group's standard error is smaller (0.14968) than the female group's (0.30028), indicating more accurate mean estimates. Once more, a statistically significant difference is indicated by a p-value of less than 0.001, with females having a larger gonial angle than males. Conclusion Our study revealed that the gonial angle of the mandible can be considered a reliable parameter for gender identification. The study's limitation is its inability to reliably identify gender in the subadult population and in cases of edentulousness. An orthopantomogram is a trustworthy and accurate method for taking the different measurements needed to identify the gender of a particular mandible.

Serotype distribution of invasive pneumococcal disease from countries of the WHO Africa, Americas, Eastern Mediterranean, South-East Asia, and Western Pacific regions: a systematic literature review from 2010 to 2021.

Background: Most publications on invasive pneumococcal disease (IPD) serotype distribution are from about 20 countries (Australia, Canada, China, European Union members, Japan, New Zealand, South Korea, and USA). Here, we reviewed the literature among underrepresented countries in the Americas (AMRO), Africa (AFRO), Eastern Mediterranean (EMRO), South-East Asia (SEARO), and Western Pacific (WPRO) WHO regions. Methods: We performed a systematic review of the most recent IPD serotype surveillance publications (from 01/01/2010 to 31/12/2021, Medline/Embase) in those WHO regions. Selection criteria were delineated by contemporality, within-country geographical scope, and number of samples. Reported serotype distributions for each country were stratified by age group, pneumococcal conjugate vaccine (PCV) serotype category (considering undifferentiated serotypes), and PCV program period (pre-PCV, intermediate, or PCVhv [higher valency PCV formulation]). Pre-PCV period pooled data estimated PCV serotype category distribution by age group across WHO regions, while for the PCVhv period, country-level dataset tables were prepared. Results: Of 2,793 publications screened, 107 were included (58 pediatric, 11 adult, 37 all ages, and one comprising every age group). One-third of eligible countries (51/135) published serotype distribution, ranging from 30 to 43% by WHO region. Considering number of samples per WHO region, a few countries prevailed: AMRO (Brazil), AFRO (South Africa, Malawi, and Burkina Faso), and WPRO (Taiwan). In the pre-PCV period, PCV13 formulation serotypes predominated: ranging from 74 to 85% in children and 58-86% in adults in the different WHO regions. The PCVhv period represented half of the most recent IPD surveillance by countries (26/51). Undifferentiated serotypes represented >20% of IPD from most countries (34/51). Conclusion: Ubiquity of undifferentiated serotypes among the publications could constrain estimates of PCV program impact and of serotype coverage for newer PCVhv formulations; consequently, we recommend that countries favor techniques that identify serotypes specifically and, rather than reporting PCV formulation serotype distributions, provide serotype results individually. Systematic review registration: The protocol has been prospectively registered at PROSPERO, identifier: CRD42021278501. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=278501.

The Effect of Life Stages on the Experience of Those Who Have Received an Unexpected and Violent Death Notification: A Qualitative Study.

BACKGROUND: How individuals are informed of the traumatic loss of a loved one can influence their grieving process and quality of life. OBJECTIVE: This qualitative study aimed to explore, through thematic analysis, how life stages might influence the experience and feelings of those who have received communication of a traumatic death from police officers or healthcare professionals. METHOD: Recruited through social networks and word of mouth, 30 people participated in the study. Subjects were divided into three groups according to age (Group 1: ten participants aged between 20 and 35 years; Group 2: ten participants aged between 45 and 55 years; and Group 3: ten participants aged 60 and over). Participants completed an ad hoc questionnaire online. Atlas.ti software 8 was used to perform thematic analysis. RESULTS: The three age groups had the following four key themes in common: (a) emotional reactions; (b) subjective valuation of the notification; (c) support; and (d) needs. Subtle differences emerged between age groups; yet the quality of the reactions and main themes did not vary greatly between the groups considered. CONCLUSIONS: The communication of an unexpected and violent death seems to provoke rather similar effects in survivors of different life stages. A few differences were noted in sub-themes (increased need for professional training in younger recipients; absence of suicidal ideation in older adults); perhaps quantitative designs could provide further details in future investigations.

Intracranial Pressure Thresholds for Cerebral Autoregulation Impairment: Age-Stratified Analysis of Ultra-Low-Frequency Pressure Reactivity Index (UL-PRx) in Traumatic Brain Injury.

BACKGROUND: The study investigated the effectiveness of low-frequency sampling in detecting alterations in cerebrovascular reactivity (CVR) associated with changes in intracranial pressure (ICP) in patients with traumatic brain injury (TBI) across different age groups. The primary objective was to investigate an ICP threshold that indicates a decrease in CVR as evidenced by a significant increase in the ultra-low-frequency pressure reactivity index (UL-PRx). Additionally, the study aimed to develop an age-based categorization method for patients with TBI to investigate the differences between these ICP thresholds in different age groups. METHODS: In this retrospective analysis, data from 263 patients with TBI were prospectively collected. ICP and mean arterial pressure were extracted from the hospital database at 5-min intervals. Demographic details, clinical presentation, computed tomography scans, neurosurgical interventions, and 12-months outcome were recorded. ICP versus UL-PRx values were categorized into ICP bins and graphically represented with boxplots for each age group, illustrating how as ICP values rise, there is a bin (age-tailored ICP [AT-ICP]) beyond which UL-PRx shows a sudden increase, indicating CVR loss. Homogeneous age groups were established to obtain a consistent AT-ICP threshold. The discriminatory ability of the AT-ICP thresholds was compared with the guideline-recommended thresholds by calculating the area under the Receiver Operating Characteristic curve of the ICP-derived indices (dose above threshold, and the hourly dosage above threshold). RESULTS: Age groups 0-5, 6-20, 21-60, 61-70, and 71-85 years were the best age subdivisions, corresponding to AT-ICP thresholds of 20, 30, 35, 25, and 30 mmHg, respectively. The AT-ICP thresholds exhibited better discriminative ability compared with the guideline-recommended thresholds. CONCLUSIONS: The AT-ICP thresholds offer a novel approach for estimating CVR impairment and the developed method represents an alternative solution to address the age stratification issue in patients with TBI.

[Total knee replacement in different age groups]. / Sravnenie lechebnogo effekta total'nogo endoprotezirovaniya kolennogo sustava v raznykh vozrastnykh gruppakh.

OBJECTIVE: To evaluate the efficacy and quality of life in long-term period (1 year) after total knee replacement in various age groups. MATERIAL AND METHODS: We studied 134 patients after unilateral primary total knee replacement. The KOOS and SF-36 questionnaires were used to assess the therapeutic effect (functionality and symptoms) and quality of life in patients with knee osteoarthritis. RESULTS: At baseline, group I (young patients) had low KOOS pain scores (39.42±16.42), function scores (50.18±19.16) and QoL scores (18.2±15.9) compared to other age groups. A year after surgery, group I (<55 years) had significantly lower KOOS scores of pain, function and quality of life compared to group III (>65 years). Multiple regression analysis showed that age was a significant predictor of pain, but not a function after a year. CONCLUSION: Total knee replacement gives a noticeable improvement in pain, functionality and quality of life in all age groups. However, there are significant age-related differences in preoperative assessment of pain, quality of life and mental health, as well as in final indicators of postoperative pain and quality of life. Indeed, young patients (<50 years) report more intense pain and worse quality of life. These data may be used in clinical practice to improve decision-making and patient expectations before total knee replacement.

Comparing times of self-harm presentations to hospital emergency departments in children, adolescents, young adults and adults: a national registry study 2007-2019.

PURPOSE: The few studies that have explored self-harm presentation times at hospital emergency departments (EDs) - an important factor that can determine if a patient receives a mental health assessment - primarily focus on adult samples. This study examined the times of self-harm presentations to EDs, self-harm methods used, mental health assessments, and admission data across different age-groups. METHODS: Using data from the National Self-Harm Registry Ireland over a 13-year timeframe (2007-2019), this study compared times, days, seasons, methods of self-harm, and admission data for children (8-12 years), adolescents (13-17 years), young adults (18-25 years) and adults (> 25 years). RESULTS: The majority of the 152,474 self-harm presentations (78.6%) for all ages occurred out-of-hours (outside the standard working hours or in-hours times of 09:00-17:00, Monday-Friday). The four hours before midnight had the highest proportions of self-harm presentations for adolescents (27.9%) and adults (23.1%), whereas the four hours after midnight had the highest proportion of self-harm presentations for young adults (22.9%). The 16:00-midnight timeframe had highest proportion of self-harm presentations in children (52.3%). Higher proportions of patients received a mental health assessment in-hours compared to out-of-hours among young adults (78.2% vs. 73.3%) and adults (76.1% vs. 72.0%). Self-harm presentations were lowest during summer months in children and adolescents. DISCUSSION: Hospitals should ensure that adequate resources are available for individuals presenting with self-harm, especially in the case of overcrowded EDs, and protocols need to be designed for those presenting with self-harm due to intoxication. In line with national policy, protocols for patients presenting during out-of-hours should be designed that can incorporate services from allied health multidisciplinary teams, social work, addiction services and counselling organisations. Given the lower rates of self-harm during school holidays for children and adolescents, the school environment must be considered in the context of mental health and self-harm public health prevention interventions.

Mitigating against relative age effects in youth Track & Field: Validating corrective adjustment procedures across multiple events.

OBJECTIVES: With the aim to better identify talented Track & Field performance development, this study estimated the relationships between chronological (decimal) age with 60-m sprint, high jump, triple jump, and pole vault performance. Then, to mitigate against expected Relative Age Effects (RAEs), Corrective Adjustment Procedures (CAPs) were applied to an independent sample. DESIGN: Mixed-longitudinal design examining public data between 2005 and 2019. METHODS: The performances of 5339 Italian sprinters and jumpers (53.1 %) spanning 11.01-17.99 years of age were examined, with trendlines between chronological age and performance established. Related to an independent sample (N = 40,306; female 45.5 %), trendlines were then utilised to apply CAPs and adjust individual performance. Considering raw and adjusted performance data, RAE distributions were examined for the top 25 % and 10 % performers. RESULTS: For all male and female events, quadratic models best summarised the relationships between chronological age and performance (R2 = 0.74-0.89). When examining independent athletes in similar event, RAEs were more pronounced in males (Cramer's V = 0.35-0.14) than females (Cramer's V = 0.29-0.07). For both sexes, RAE magnitude decreased with age and increased according to performance level (i.e., Top25%-Top10%). However, following CAP applications, RAEs were reduced or removed within annual age groups and performance levels. CONCLUSIONS: With RAEs prevalent across Italian youth Track & Field events, findings validate CAPs as a strategy to account for the influence of relative age differences on athletic performance. CAPs help establish a more equitable strategy for performance evaluation and could help improve the efficacy of long-term athlete development programming.

Disparity in guideline adherence for prehospital care according to patient age in emergency medical service transport for moderate to severe trauma.

OBJECTIVES: The aim of this study was to investigate the association between patient age and guideline adherence for prehospital care in emergency medical services (EMS) for moderate to severe trauma. METHODS: This was a retrospective observational study that used a nationwide EMS-based trauma database from 2016 to 2019. Adult trauma patients whose injury severity score was greater than or equal to nine were screened, and those with cardiac arrest or without outcome data were excluded. The enrolled patients were categorized into four groups according to patient age: young (<45 years), middle-aged (45-64 years), old (65-84 years), and very old (>84 years). The primary outcome was guideline adherence, which was defined as following all prehospital care components: airway management for level of consciousness below verbal response, oxygen supply for pulse oximetry under 94 %, intravenous fluid administration for systolic blood pressure under 90 mmHg, scene resuscitation time within 10 min, and transport to the trauma center or level 1 emergency department. Multivariable logistic regression was conducted to calculate the adjusted odds ratios (aORs) and 95 % confidence intervals (95 % CIs). RESULTS: Among the 430,365 EMS-treated trauma patients, 38,580 patients were analyzed-9,573 (24.8 %) in the young group, 15,296 (39.7 %) in the middle-aged group, 9,562 (24.8 %) in the old group, and 4,149 (10.8 %) in the very old group. The main analysis revealed a lower probability of guideline adherence in the old group (aOR 95 % CI = 0.84 (0.76-0.94)) and very old group (aOR 95 % CI = 0.68 (0.58-0.81)) than in the young group. CONCLUSION: We found disparities in guideline adherence for prehospital care according to patient age at the time of EMS assessment of moderate to severe trauma. Considering this disparity, the prehospital trauma triage and management for older patients needs to be improved and educated to EMS providers.

Early gastric cancer of young patients treated by endoscopic submucosal dissection: focusing on the different characteristics and prognosis of elderly patients.

BACKGROUND: A small portion of patients are diagnosed with early gastric cancer (EGC) and undergo endoscopic submucosal dissection (ESD) at a young age. However, their clinical outcomes are rarely known. AIM: We investigated to identify the feasibility and clinical outcomes of ESD for EGC focusing on young patients. METHODS: We analyzed the clinical characteristics and outscomes of patients who had undergone ESD for the treatment of EGC at < 50 years of age. We enrolled patients who had been diagnosed with EGC and had undergone ESD between 2006 and 2020. We divided them by age as follows: ≤ 50 and > 50 years into the young age (YA) and other age (OA) groups, respectively. RESULTS: Altogether, 1681 patients underwent ESD for EGC (YA group: 124 [7.4%], OA group: 1557 [92.6%]). The YA group had less severe atrophy and more undifferentiated (37.1% vs. 13.9%, P < 0.001) and diffuse type (25% vs. 7.7%, P < 0.001) histology. The curative resection rate was not significantly different between the groups. However, among 1075 patients who had achieved curative resection and had been followed-up for > 12 months, the YA group had a lower incidence of MGN (5.2% vs. 17.5%, P = 0.004) and MGC (2.6% vs. 10.9%, P = 0.019) than those exhibited by the OA group. The YA group was a significant negative predictor of MGN (odds ratio [OR]: 2.983, 95% confidence interval [CI] 1.060-8.393, P = 0.038), and marginally negative predictor in MGC (OR: 3.909, 95% CI: 0.939-16.281, P = 0.061). CONCLUSION: ESD is a favorable and effective therapeutic modality for EGC patients aged < 50 years, once curative resection is achieved.

Improving associative memory in younger and older adults with unitization: evidence from meta-analysis and behavioral studies.

Introduction: The finding that familiarity can support associative memory by unitizing the to -be-learned items into a novel representation has been widely accepted, but its effects on overall performance of associative memory and recollection are still controversial. Methods: The current study aims to elucidate these discrepancies by identifying potential moderating factors through a combined approach of meta-analysis and behavioral experiment. Results: Results consistently showed that changes in the level of unitization and age groups were two important moderators. Specifically, unitization enhanced younger and older adults' associative memory and its supporting processes (i.e., familiarity and recollection) when the level of unitization between studied and rearranged pairs was changed. However, when this level remained constant, unitization exhibited no impact on associative memory and familiarity in younger adults, but showed an enhanced effect in older adults. Furthermore, results revealed a marked group difference between younger and older adults in associative memory when the unitization level of noncompound words remained unaltered. Upon breaking this condition, the group difference was reduced by enhancing familiarity or recollection. Discussion: These findings not only clarify some of the inconsistencies in the literature concerning the impact of unitization on associative memory, but also suggest that unitization is a beneficial strategy for reducing group difference in associative memory, with its effectiveness varying according to the level of unitization changes.

A metric for comparison and visualization of age disparities in cancer survival.

AIMS: Diagnostic age is an important determinant of cancer survival but the methods generally used to analyze age-group-specific survival are not developed for ready visualization of survival differences. We aim at developing a novel metric for comparing and visualizing age-group-specific survival data over different cancers, sexes, periods and countries. METHODS: The metric describes the mean absolute deviation between age-groups. The metric can be used in two variations, one showing the mean variation and its 95% confidence intervals and the other highlighting individually each age-groups distinguishing positive or negative deviations. We demonstrate the applications with age-group- specific 5-year relative survival data from the NORDCAN database RESULTS: The mean absolute deviation between age-groups for Swedish colon cancer survival declined from about 5% in 1972-1981-1% in 1992-2001 and to 1.3% in 2012-2021. Patients diagnosed before age 50 years accounted for the largest positive deviation. For acute myeloid leukemia (AML) the mean deviation increased from 4% (female) to 17% and 23%. Patients diagnosed at age below 50 years showed the largest deviations. Comparing colon cancer mean deviations between the Nordic countries, a time-related decline was observed for all, those in Sweden ending at the lowest and in Finland the highest level. CONCLUSIONS: We demonstrated the usefulness of the devised metric for summarizing age-specific survival data between cancers, sexes, periods and countries. The two variations of the metric allow a simple visual presentation of the survival experience as to deviation of the survival data, its 95%CIs and its highlighted individual age-group components.

Impact of age on tumor characteristics and treatment outcomes in pediatric Differentiated Thyroid Carcinoma.

PURPOSE: There is a tendency to use data generated for adults in the management of pediatric Differentiated Thyroid Carcinoma, neglecting the clinical peculiarities of this condition in childhood. This study aimed to assess and compare the clinical-epidemiological characteristics and their significance in the evolution of thyroid carcinoma diagnosed in childhood across different age groups. METHODS: Seventy-seven patients diagnosed with Differentiated Thyroid Carcinoma (DTC) up to 21 years old were selected and divided into different age groups: up to 10 years, 11 to 18 years, and 19 to 21 years old. Clinical-epidemiological data and their influence in the disease progression were analyzed and compared across age groups. RESULTS: Patients diagnosed below 10 years of age were associated with tumors showing extrathyroidal extension, metastasis in regional lymph nodes, higher levels of stimulated thyroglobulin in the diagnostic iodine-131 whole-body scan (WBS), and under TSH suppression in the last assessment. Additionally, pulmonary metastasis were associated in both diagnostic and post-radioiodine dose WBSs in these younger patients. Analysis of findings in the post-radioiodine therapy WBS revealed significant differences between all age groups (p = 0.0029). The time of diagnosis was identified as a factor associated with an excellent response in subgroups up to 18 years and up to 21 years. No factors associated with dynamic responses over the 1st, 3rd and 5th years of follow-up and the persistence/recurrence of the disease were identified in the subgroup up to 18 years. In the subgroup up to 21 years, having an incomplete structural response in the 3rd year of follow-up increased the chances of recurrent or persistent response by 5.5 times, and by 32.6 times if found in the 5th year of follow-up. CONCLUSIONS: Younger patients exhibited more aggressive tumor characteristics and underwent more rigorous treatment. However, treatment response and disease status in the last assessment, whether free or recurrent/persistence, were similar when comparing the age groups of 11 to 18 and 19 to 21 years. Nonetheless, responses obtained in the 3rd and 5th years post-treatment emerged as factors associated with the persistence/recurrence of the disease in the last assessment in the age group up to 21 years but not in patients diagnosed up to 18 years, a relevant distinction considering the tumor behavior in defining the pediatric age range in thyroid cancer.

Prevalence of and factors influencing Hikikomori in Osaka City, Japan: A population-based cross-sectional study.

OBJECTIVES: Hikikomori is commonly defined as a social condition in which individuals avoid social participation and relationships beyond their family members by confining themselves to a room or their house for 6 months or longer. Hikikomori has been predominantly considered a problem among young people; however, as the population is ageing, hikikomori has also emerged as a social issue among adults. Nevertheless, no comparative studies have examined the differences in the factors associated with hikikomori among teenagers/young adults and middle-aged/older adults. Thus, this phenomenon has not been thoroughly examined, and it remains unclear whether the risk factors vary between teenagers/young adults and middle-aged/older adults. Based on the Japan Cabinet Office's definition of hikikomori, this cross-sectional study evaluated the prevalence and related factors of hikikomori among the working age population (15-64 years), utilising univariate and multivariate analyses. The study also compared differences in the prevalence of and factors related to hikikomori between teenagers/young adults and middle-aged/older adults. METHODS: We distributed self-administered questionnaires to individual participants and their families between 24 December 2020 and 18 January 2021. RESULTS: Data from an anonymised sample of 3,092 individuals (split into two groups of 15-39 and 40-64 years) were subjected to analysis. The results revealed a hikikomori prevalence of 2.3% in the target population; the prevalence rate was 2.12% among individuals aged 15 to 39 years and 2.42% among those aged 40 to 64 years. The analysis demonstrated strong correlations between hikikomori and several factors, including unemployment, truancy, a history of psychiatric consultation or hospitalisation, being male and the absence of ibasho, which is defined as a place where individuals can feel peace, security, acceptance and belonging. The factors associated with hikikomori differed between teenagers/young adults and middle-aged/older adults. CONCLUSION: Our findings, thus, contribute to existing research by providing a comparative analysis of risk factors across different age groups.

Do age, gender, and subjective health-related factors influence health-related life satisfaction in people with disabilities who are physically active?: a secondary analysis.

PURPOSE: This study explored the factors influencing the health-related life satisfaction of people with disabilities who engaged in physical activity, by age and gender. METHODS: A secondary analysis was conducted of the 2020 Third Disability and Life Dynamics Panel (2021). The participants were 2,796 people who performed regular physical activity at least once a week. The variables selected were disability-related factors (degree of disability, multiple disabilities, and type of disability), sociodemographic factors (age, gender, living alone, and mean monthly family income), and health-related factors (amount of physical activity, self-esteem, depression, chronic disease, subjective health, and health-related life satisfaction). Descriptive statistics, the chi-square test, the t-test, two-way analysis of variance, and multiple regression analysis were conducted. RESULTS: In total, 58.0% of participants were male, and 42.0% were female. For age groups, 14.4% were children/adolescents (0-19 years), 42.6% were adults (20-59 years), and 43.0% were seniors (≥60 years). The mean score for health-related life satisfaction was 5.0±2.15 out of 10. Adults and seniors whose level of physical activity met or exceeded recommendations had higher subjective health. Moreover, men had better subjective health than women in seniors. Health-related life satisfaction was higher among those who had higher self-esteem, were not depressed, did not have chronic diseases, and had better subjective health. CONCLUSION: Gender significantly influenced health-related life satisfaction in children/ adolescents and seniors. Disability-related factors were significant in adults, and health-related factors were significant in all age groups. Therefore, these factors should be considered when designing interventions to promote subjective health and health-related life satisfaction of people with disabilities.
