The COVID-19 pandemic and preventive measures such as social distancing massively affected individuals' activities in different spaces. For example, social spaces such as restaurants, parks, and movie theaters are closed. To understand how adapted practices have changed the meanings and use of different spaces in the context of the pandemic, we conducted semi-structured interviews with 30 individuals living alone in a Midwestern state of the USA, focusing on changes in activities and spaces where these activities used to take place. Our findings revealed that non-technological (e.g., making slight adjustments, finding alternatives) and technological (e.g., transitioning to the virtual sphere) adaptation strategies changed the relationships between space and activity while reshuffling and decoupling activities from their usual spaces during the pandemic. Based on the findings, we propose a framework illustrating different space-activity dimensions to reflect the evolved relationships between space and activity. The framework will facilitate exploring associated challenges and opportunities for potential research and design of technology for adapted activities decoupled from the physical spaces. Towards that goal, we present design implications for future socio-technical systems to support adapting space and activities in the context of COVID-19. [ABSTRACT FROM AUTHOR]

Abstract Objective This study aimed to investigate the associations between physical activity (PA) intensity, occupational PA engagement, and sarcopenia in younger adults. Methods Data from the National Health and Nutrition Examination Survey (NHANES) (from 2011 to 2018) were used for the study. PA data were extracted for the Global Physical Activity Questionnaire, and the ratio of limb muscle mass (ALM) to body mass index (BMI) was used to determine sarcopenia. Multiple logistic regression was performed, and dose-response curves were drawn to evaluate the associations. Results Of the 8802 adults aged 20 to 59 years, 770 (8.7%) were identified as having sarcopenia. Compared to those in the reference group, the participants in the “low”, “moderate”, and “high” total METs groups had lower risks of sarcopenia (low: OR = 0.730, 95% CI = 0.583; 0.915; moderate: OR = 0.643, 95% CI = 0.485; 0.853; high: OR = 0.560, 95% CI = 0.457; 0.687). The risk of sarcopenia decreased in the high-intensity recreational PA group; however, such a significant association was observed only in the high-intensity occupational PA group. The relationship between total METs and sarcopenia showed a nonlinear U-shaped trend. Conclusions A greater intensity of PA is associated with a lower risk of sarcopenia among younger adults, regardless of whether moderate or vigorous PA is performed. Moreover, recreational PA may particularly advantageously contrast with occupational PA in lowering the risk of sarcopenia.

Simple Summary: This study addresses the ongoing scientific debate regarding the existence, causes, characteristics and reversibility of cognitive sequelae associated with COVID-19 infection. The aim of the study is to describe the neuropsychological profile of individuals diagnosed with COVID-19, distinguishing between younger (<65 years) and older (≥65 years) adults and evaluating them at baseline and at 3 and 6 months after infection. Significant differences in cognitive performance between younger and older adults are observed, consistent with their different physiological conditions. However, distinct memory recall patterns not attributable to physiological differences are also observed. The results contribute to the understanding of COVID-19 cognitive sequelae, suggesting that cognitive deficits in COVID-19 survivors may primarily reflect difficulties in attention and concentration impacting retrieval processes, aligning with the concept of "brain fog" associated with post-COVID-19 syndrome. The literature on COVID-19 continues to increase daily. Cognitive sequelae associated with COVID-19 infection still draw the attention of the scientific community given the lack of consensus about their existence, etiology, characterization and reversibility. The aim of this study is to provide a neuropsychological identikit for younger (<65 years) and older (≥65 years) individuals diagnosed with COVID-19 infection, at baseline and after 3 and 6 months. In total, 226 individuals took part in a retrospective observational study and their cognitive performance was compared across groups (younger adults vs. older adults) and time (T0, T1, T2). The results highlighted differences between younger and older adults in the Montreal Cognitive Assessment (MoCA) global score, as expected in consideration of the different physiological conditions of the two populations. However, memory performance highlighted the two groups as characterized by a difference in patterns of recall that may move beyond a physiological explanation and provide information about COVID-19 cognitive sequelae. This study suggests that cognitive deficits observed in COVID-19 survivors may reflect a difficulty in attention and concentration that interferes mainly with retrieval processes. This result fits well with the concept of "brain fog" typical of post-COVID-19 syndrome and may also reflect the stress experienced while facing the pandemic. [ABSTRACT FROM AUTHOR]

Objective: Guidelines for statin therapy emphasize treatment of adults ages 40–75 years, with less guidance for the treatment of younger adults, ages 20–39 years. Only two class 1 recommendations for statin apply to younger adults: 1) secondary prevention and 2) severe hypercholesterolemia (LDL-C ≥ 190 mg/dL). The implementation of guidelines within this age group has not been well studied. Methods & Results: Here, we use data from the National Health and Nutrition Examination Survey (2013–2020) to estimate statin eligibility and use among US younger adults. Based on this nationally representative sample, we extrapolate that approximately 923,000 younger adults had a history of atherosclerotic cardiovascular disease, but only ∼24 % were on statin. Among younger adults in the primary prevention group, we extrapolate that at least 1.09 million had severe hypercholesterolemia. To expand on this analysis, we calculated untreated LDL-C values for individuals on statin using two methods, and we estimate that only ∼11–20 % of younger adults with severe hypercholesterolemia were on statin. Lastly, among untreated younger adults with a class 1 indication for statin, fewer than 25 % reported that a doctor or healthcare provider had recommended cholesterol medication. Conclusion: The implementation of class 1 recommendations for statin treatment in younger adults is poor. While efforts to improve risk prediction in the young have recently received significant attention, our results indicate that identifying high risk younger adults is insufficient. We must also improve guideline-recommended treatment in this age group.

Little is known about generational differences and similarities in beliefs about addiction. Science Gallery Atlanta (SGA) integrates science and art to approach challenging topics, like addiction, with empathy. Intergenerational communication about addiction could positively impact older and younger adults. This study investigated perceptions of addiction among older (60+ years) and younger (18–26 years) adults through intergenerational dialogue on addiction-focused art, offered through SGA’s HOOKED exhibition. This exploratory pilot study recruited ten randomized older-younger dyads who received a mediated tour of HOOKED. Addiction attitudes were assessed pre- and post-tour with the Belief in a Just World and Addiction Belief Scale questionnaires, concurrent interviews, and focus groups. Qualitative data were recorded, transcribed and analyzed thematically. Thematic analysis revealed younger and older adults were equally concerned with addiction-produced waste and technology addiction. Generational differences emerged regarding social media and drug-induced euphoria. Across age groups, participants scored similarly in their beliefs about justice for others and self. Post-tour, young adults were more likely to view addiction as a disease rather than a choice (p = 0.05). Art-based intergenerational communication may increase empathy. Intergenerational bridging may help young adults see addiction as a disease and older adults understand behavioral addictions. Emergent themes illuminate generational differences and similarities in addiction beliefs. [ABSTRACT FROM AUTHOR]

Simple Summary: Older adults with metastatic cancer of the urinary tract often do not receive optimal cancer treatments. Through our real-world study at a tertiary cancer center, we investigated the clinical characteristics, treatment patterns, and outcomes among older patients compared to younger adults receiving first-line systemic treatment. We found that older patients tend to be more suited to receiving immunotherapy and lower amounts of chemotherapy. When treated with regimens tailored to their overall health, they tolerate treatment as well as younger patients and experience similar life-prolonging benefits from these. Our results further reinforce that age alone is not a predictive factor for survival in patients who receive systemic treatment for advanced cancer. These findings suggest the need for appropriate treatment selection and tailored regimens for older adults with metastatic cancer of the urinary tract. Metastatic urinary tract cancer (mUTC) is challenging to treat in older adults due to comorbidities. We compared the clinical courses of younger and older (≥70 years) adults with mUTC receiving first-line (1L) systemic therapy in a tertiary cancer center. Baseline clinical characteristics, treatments received, tolerability, and survival outcomes were analyzed. Among 212 patients (103 older vs. 109 younger), the older patients had lower hemoglobin at baseline (84% vs. 71%, p = 0.03), the majority were cisplatin-ineligible (74% vs. 45%, p < 0.001), received more immunotherapy-based treatments in the 1L (52% vs. 36%, p = 0.01), received fewer subsequent lines of treatment (median 0 vs. 1, p = 0.003), and had lower clinical trial participation (30% vs. 18%, p = 0.05) compared to the younger patients. When treated with 1L chemotherapy, older patients required more dose adjustments (53.4% vs. 23%, p = 0.001) and received fewer cycles of chemotherapy (median 4 vs. 5, p= 0.01). Older patients had similar OS (11.2 months vs. 14 months, p = 0.06) and similar rates of treatment-related severe toxicity and healthcare visits, independent of the type of systemic treatment received, compared to younger patients. We conclude that select older adults with mUTC can be safely treated with immunotherapy and risk-adjusted regimens of chemotherapy with tangible survival benefits. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to explore the association of cognitive function and process- as well product-oriented outcomes of object control skills (OCS) in boys, younger and older men. Methods: A total of 77 male participants took part in this study, including 35 primary school children (9.04 ± 0.53 years), 22 younger adults (23.5 ± 2.34 years), and 20 older adults (69.5 ± 4.43 years). We assessed the process-oriented performance of throwing, kicking, and catching performance using the component approach. For the product-oriented performance, throwing and kicking velocity was recorded with a STALKER SOLO 2.0 radar gun. For catching, the number of caught balls was assessed. Cognitive function was evaluated using the Trail-Making-Test (TMT) one day later. Results: Younger adults performed better in both domains than the other two groups. The results of the children and older adults were comparable in the motor and cognitive domains. However, the older adults yielded significantly better results for the process-oriented catching and product-oriented throwing performances. Moderate to strong correlations exist between OCS- and TMT performance, with significant correlations predominantly between product-oriented OCS results and TMT in children. Conclusion: The results of both domains support a hypothetical lifespan developmental trajectory with a progression from childhood to younger adult age and a degression in older adults. Furthermore, our results suggest that the suspected relationship between motor and cognitive function depends on age, the analyzed cognitive and motor skills, and the applied methodological approach (process-oriented vs. product-oriented).

The Mediterranean dietary pattern (MPD) has shown promise in preventing low-grade systemic inflammation (LGSI). This study tested if a high adherence to the MDP by younger and older Brazilian adults is associated with lower LGSI and investigated which Mediterranean food components may contribute to these associations. We performed a secondary study on 2015 ISA-Nutrition (290 younger adults (20–59 years old) and 293 older adults (≥60 years old)), a cross-sectional population-based study in São Paulo, SP, Brazil. The adherence to the MDP was assessed using the Mediterranean Diet Score (MedDietScore), obtained from two non-consecutive 24 h dietary recalls (24HDRs). The LGSI score (from plasma CRP, TNF-α, and adiponectin) identified the inflammatory status. Linear regression models assessed the association between LGSI and the MedDietScore. In older adults only, a high adherence to the MDP signified an 11.5% lower LGSI score. Older adults, classified with high adherence to the MDP, differed by consuming lower meat intake and full-fat dairy. Between older adults, the intake of vegetables and olive oil was inversely associated with the levels of LGSI. Thus, among older adults, the intake of some specific Mediterranean food determined high adherence to the MDP and was associated with decreased LGSI. [ABSTRACT FROM AUTHOR]

As the number of young adults moving to urban areas increases, so does the number of older parents who are left behind in rural areas, where they face loneliness, isolation, hunger, and a lack of social support and care. The lack of remittances and alternative arrangements for caring for the migrant children's elderly parents, as well as the lack of social support networks, makes it difficult for them to cope on their own. The purpose of this study is to ascertain how the migration of younger adults affects the well-being of the left-behind older parents in Nsukka LGA, Enugu State, and to recommend ways to improve their living conditions. Twenty-four elderly parents were purposively chosen for the study. An in-depth interview method was employed for data collection. Using themes and quotes, the generated data were transcribed and analyzed. According to the study, young adults migrate to cities due to poverty, lack of employment and business opportunities, poor hospitals and schools, and lack of social amenities in rural areas. The study also discovered that elderly parents who are left behind in rural areas face hardship and neglect. As a result, to discourage unnecessary migration, we advocated for massive and aggressive rural infrastructure development. Furthermore, social workers should be involved in advocating for elderly social support systems. [ABSTRACT FROM AUTHOR]

Background: Low viral load suppression rates among older adolescents and young adults with HIV are a global challenge, including in Namibia. Healthcare providers struggle with managing these age groups due to their unique demographic characteristics. Monitoring viral load suppression is vital for evaluating antiretroviral treatment effectiveness, making it essential to identify and address existing gaps. Objectives: This study aimed to explore and describe healthcare practitioners’ understanding and experiences in managing older adolescents and younger adults living with HIV in seven high-burden districts of Namibia. Method: Qualitative descriptive phenomenological research was followed in this study. Healthcare practitioners directly managing older adolescents and younger adults living with HIV were purposively recruited. Telephonic individual interviews were conducted, and data saturation was achieved with the 29th participant. Colaizzi’s seven-step analysis was used to analyse the data. Results: Two themes emerged from the study: (1) healthcare practitioners’ knowledge of viral load management and (2) the strategies employed to manage high viral load in these age groups. These strategies included implementing differentiated service delivery, adopting interprofessional and Ubuntu approaches, psychosocial support, community engagement, enhancing adherence counselling, and support from implementing partners. Conclusion: The findings revealed inadequate knowledge among healthcare practitioners regarding viral load management, which negatively impacts the provision of quality care and an effective HIV response within the spirit of Ubuntu. Contribution: This study enhances healthcare practitioners’ capacity in viral load management and guides policy makers in supporting this unique population, thus improving their health outcomes.

Introduction: Although frailty is commonly considered as a syndrome of old individuals, recent studies show that it can affect younger adults, too. Whether and how frailty differs in younger adults compared to old is however unknown. To this end, we analyzed the prevalence, characteristics, and risk factors of early-life (aged <65) and late-life (aged ≥65) frailty. Methods: We analyzed individuals in the UK Biobank (N = 405,123) and Swedish Screening Across the Lifespan Twin (SALT; N = 43,641) study. Frailty index (FI) scores ≥0.21 were used to demarcate frailty. Characteristics of early-life versus late-life frailty were analyzed by collating the FI items (deficits) into domains and comparing the domain scores between younger and older frail individuals. Logistic regression was used to assess the risk factors of frailty. Results: The pooled prevalence rates of frailty were 10.3% (95% confidence interval [CI]: 2.7–32.7), 14.4% (95% CI: 4.5–37.2), 19.2% (95% CI: 2.5–68.5) in individuals aged ≤55, 55–64, 65–74, respectively. Younger frail adults (aged <65) had higher scores in immunological, mental wellbeing, and pain-related domains, whereas older frail adults (aged ≥65) had higher scores in cardiometabolic, cancer, musculoskeletal, and sensory-related domains. Higher age, female sex, smoking, lower alcohol consumption, lower education, obesity, overweight, low income, and maternal smoking were similarly associated with the risk of early-life and late-life frailty. Conclusion: Frailty is prevalent also in younger age groups (aged <65) but differs in some of its characteristics from the old. The risk factors of frailty are nevertheless largely similar for early-life and late-life frailty. [ABSTRACT FROM AUTHOR]

Older adults adapt the execution of complex motor tasks to use compensatory strategies in the reaching-to-grasping (i.e., prehension) movement. The presence of postural constraints may exacerbate these compensatory strategies. Therefore, we investigated the reach-to-grasp action with different postural constraints (sitting, standing, and walking) in younger and older people and evaluated the postural stability during the reach-to-grasp action. Thirty individuals (15 younger and 15 older adults) performed the prehension under three postural tasks: sitting, standing, and walking. The reaching movement was slower in the walking task than in the other two postural tasks; however, there was no difference between the age groups. For the grasping action, the older adults presented a larger grip aperture, and the peak grip aperture occurred earlier during hand transportation in sitting and standing tasks. In the standing task, the margin of stability was smaller for older adults. In the walking task, there was no difference between the groups for the margin of stability. Also, prehension during sitting and standing tasks were similar, and both differed from walking across age groups. Finally, older adults reduced their margin of stability compared to younger adults, but only in the standing task. The margin of stability was similar between age groups during the walking task. We concluded that age affected grasping (distal component) but not reaching (proximal component), suggesting that healthy older adults have more difficulty controlling distal than proximal body segments.

Research on quality of life (QOL) factors important for younger adults (ages 18–45 years old) with osteoarthritis (OA) is limited. This study utilizes an online survey method to conduct an expert panel review of QOL domains for this population. Health provider and young adult perspectives of living with OA were captured and compared. Results indicate that providers are underestimating the impact OA is having on a variety of QOL factors for younger adults. Overall, these results reveal critical QOL domains to consider during assessment and when considering intervention strategies aimed at improving the lives of younger adults with this chronic disease. Implications for social work are also discussed. [ABSTRACT FROM AUTHOR]

Abstract Objective People gather information about health topics from online channels oftentimes awash with misinformation. Investigating this problem during the COVID-19 pandemic is important, as the misinformation effect occurs when misleading details are embedded in narratives and questions. This pilot study investigated whether narrative elaboration increases believability in misinformation statements about COVID-19, and willingness to share these statements online. Results Results from our online survey (n = 80) demonstrated that narrative elaboration increased believability in both misinformation and accurate statements, with a more pronounced effect on younger adults. Future research may investigate cognitive vulnerabilities imposed by elaborate narratives embedded in online health misinformation with increased attention on developing misinformation resilience among younger adults.

Purpose: Hip fracture is associated with high morbidity and mortality. The most common complication after hip fracture is surgical site infection (SSI). The goal was to investigate risks associated with SSI in young adults who underwent surgery for hip fractures.Methods: We conducted a case-control study enrolling 1243 patients from Jan 2015 to Dec 2019. This study investigated the multifaceted factors including demographics, lifestyles, comorbidities, surgical variables, and laboratory test results. Patients were divided into the case group (developed SSI) and control group (not developed SSI). Univariate analyses and multivariate logistic regression analyses were used to identify the risk factors independently associated with SSI.Results: A total of 25 patients including 16 (1.8%) in femoral neck fracture and nine (2.5%) in intertrochanteric fracture developed SSI post-operatively, with an accumulated incidence rate of 2.0%. Among them, four cases (1.6%) were deep SSI and 21 cases (98.4%) were superficial SSI. In most cases, Staphylococcus aureus caused the infections. Diabetes mellitus (OR 4.05, 95%CI: 1.08-15.23, P = 0.038), cerebrovascular disease (OR 3.71, 95%CI: 1.14-12.03, P = 0.029), heart disease (OR 6.23, 95%CI: 1.81-21.48, P = 0.004), and operative time (OR 1.01, 95%CI: 1.01-1.02, P = 0.002) in femoral neck fractures while ALP (> upper limit) (OR 33.39, 95%CI: 2.21-504.89, P = 0.011) and CK (> upper limit) (OR 40.97, 95%CI: 1.70-989.31, P = 0.022) in intertrochanteric fractures were found to be significantly associated with SSI.Conclusion: Targeted pre-operative management, depending on the patients' fracture type and risk factors, should be developed to reduce post-operative SSI rates of younger adults with hip fracture.

Objectives: Growing evidence suggests that repeated-dose intravenous ketamine in patients with depression had rapid antianhedonic effects. However, a comparison of the antianhedonic effects of repeated-dose intravenous ketamine between younger adults and older depressed patients has not been examined., Methods: To the best of my knowledge, this study with a total of 135 patients with major depressive episodes (MDE) is the first to compare the antianhedonic effects between younger adult (n = 116) and older (n = 19) depressed patients receiving six ketamine infusions (0.5 mg/kg over 40 min). Montgomery- Åsberg Depression Rating Scale (MADRS) was applied in this study to evaluate the clinical symptoms, and MADRS anhedonia item scoring was used to evaluate anhedonia symptoms., Results: Patients received six open-label intravenous infusions of ketamine for 12 days. MADRS anhedonia subscale scores decreased in both younger (3.3, 95% CI = 2.5-4.1, p < 0.05) and older (2.8, 95% CI = 1.1-4.6, p < 0.05) MDE patients at 4h after the first infusion compared to baseline scores and the reduction was maintained over the subsequent infusion period in both groups (all Ps < 0.05). Younger MDE patients had lower MADRS anhedonia subscale scores on day 26 compared with older patients (P = 0.02). Compared with younger adult MDE patients, older patients had a lower antianhedonic response (51.7% [95% CI = 42.5%-61.0%] versus 31.6% [95% CI = 8.6%-54.6%)] and remission (24.1% [95% CI = 16.2%-32.0%] versus 0%)., Conclusion: This study indicates that repeated-dose intravenous ketamine administration induces rapid and robust antianhedonic effects in older MDE patients. However, older MDE patients displayed less response to ketamine than younger adult MDE patients., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Drawing upon uses and gratifications perspectives and socioemotional selectivity theory, this study examined the differences in the use of Facebook features among younger, middle-aged, and older adults. Furthermore, it explored the association between Facebook activities and users' perceived enjoyment for different age groups. An online survey was conducted with 647 Facebook users in the United States. An exploratory factor analysis identified four types of Facebook activities: broadcasting, directed communication, content consumption, and information regulation. The results revealed that younger users' broadcasting, content consumption, and information regulation activities substantially differed from those of older users. In addition, broadcasting and content consumption activities were more popular among younger users and more predictive of their enjoyment. Directed communication was more powerful in predicting middle-aged and older users' enjoyment. However, younger and middle-aged users' engagement with information regulation activities was negatively related to their enjoyment of Facebook. The study findings provide more nuanced knowledge regarding user experiences on social media platforms among specified age groups and practical insights into the improvement of social media by addressing their different needs.

(1) Background: The association of sugar-sweetened beverages (SSBs) with cardiovascular disease (CVD) mortality in younger adults (age 20–39) is rarely mentioned in the literature. Younger adults are less vulnerable to CVDs, but they tend to consume more SSBs. This prospective study aimed to assess the association between CVD mortality and SSBs in younger adults between 1994 and 2017. (2) Methods: The cohort enrolled 288,747 participants consisting of 139,413 men and 148,355 women, with a mean age 30.6 ± 4.8 years, from a health surveillance program. SSBs referred to any drink with real sugar added, such as fructose corn syrup or sucrose. One serving of SSB contains about 150 Kcal of sugar in 12 oz of drink. Cox models were used to estimate the mortality risk. (3) Results: There were 391 deaths from CVDs in the younger adults, and the positive association with CVD mortality started when SSB intake was ≥2 servings/day (HR: 1.59, 95% CI: 1.16–2.17). With mortalities from diabetes and kidney disease added to CVDs, the so-called expanded CVD mortality risk was 1.49 (95% CI: 1.11–2.01). By excluding CVD risk factors (hypertension, diabetes, and smoking), the CVD mortality risk increased to 2.48 (95% CI: 1.33–4.62). The dose–response relationship persisted (p < 0.05 for trend) in every model above. (4) Conclusions: Higher intake of SSBs (≥2 servings/day) was associated with increased CVD mortality in younger adults. The younger adults (age 20–39) with SSB intake ≥2 servings/day had a 50% increase in CVD mortality in our study, and the mortality risk increased up to 2.5 times for those without CVD risk factors. The dose–response relationship between the quantity of SSB intake and the mortality risk of CVD in younger adults discourages SSB intake for the prevention of CVD mortality. [ABSTRACT FROM AUTHOR]

Abstract Background The Hospital Readmissions Reduction Program (HRRP) was introduced to reduce readmission rates among Medicare beneficiaries, however little is known about readmissions and costs for HRRP-targeted conditions in younger populations. The primary objective of this study was to examine readmission trends and costs for targeted conditions during policy implementation among younger and older adults in the U.S. Methods We analyzed the Nationwide Readmission Database from January 2010 to September 2015 in younger (18–64 years) and older (≥65 years) patients with acute myocardial infarction (AMI), heart failure (HF), pneumonia, and acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Pre- and post-HRRP periods were defined based on implementation of the policy for each condition. Readmission rates were evaluated using an interrupted time series with difference-in-difference analyses and hospital cost differences between early and late readmissions (≤30 vs. > 30 days) were evaluated using generalized linear models. Results Overall, this study included 16,884,612 hospitalizations with 3,337,266 readmissions among all age groups and 5,977,177 hospitalizations with 1,104,940 readmissions in those aged 18–64 years. Readmission rates decreased in all conditions. In the HRRP announcement period, readmissions declined significantly for those aged 40–64 years for AMI (p

Background: The oral squamous cell carcinoma (OSCC) often affects elderly aged adults, who had long-term tobacco exposure. In the recent past decade, there is an increasing incidence of OSCC in younger individuals, who had less tobacco association. Aim: The aim of this study is to examine the risk factors and to assess and compare the clinicopathological features and prognosis of OSCC in young patients with the older group patients. Materials and Methods: We included studies that addressed the OSCC involving young patients during the period between 2014 and 2019. Initially, we found 679 articles; after refined evaluation, 92 works had their titles matching to the present work. After extraction of case reports, reviews, and studies with un-matched objectives or inadequate data, we have chosen only 24 presentations matching to the abstract. The statistical analysis performed by Chi-square tests using SPSS 20.0 version for windows. Results: Of the total OSCC, 10% of patients belonged to the younger age group, and 90% were the older aged group. Both the groups showed male gender predominance and tongue as the predominant site of involvement. The younger patients tend to have significantly reduced tobacco exposure. The highly reported tumors were advanced staged and moderately differentiated tumors in both groups. There was a statistically evident high recurrence reported in the younger group. The overall survival seems to be similar for both groups. Conclusion: The identification of the potential risk factors, along with unique molecular mechanisms, and biological behavior of the disease is mandatory to control the incidence of OSCC in young adults.

In this cross-sectional study, adverse events after the first and second dose of BNT162b2 mRNA (Pfizer-BioNTech, Comirnaty) vaccine against coronavirus disease 2019 were investigated among employees of clinics in central Italy. A 42-items questionnaire was administrated to vaccine recipients. Adverse events were classified based on severity and occurrence as reported in the literature. A descriptive/univariate analysis using Chi-square or Fisher's Exact tests was performed. Odds ratio (OR) and 95% confidence intervals were calculated to assess risk factors. 340 individuals (61.5% females; median age 49 years) participated. Adverse events were reported by 279 (82%) and 281 (82.6%) individuals as induced by the first and second dose, respectively. Mild reactions were mainly reported (80.9% and 80.3%), followed by moderate (11.8% and 37.1%) and severe (3.8% and 4.7%). Adverse events were identical to those already described as very common (81.8% and 80.6%), although vaccine-coincidental events not cited in the literature were reported by 6% and 15.6% following each dose. Age ≤ 55 years was a risk factor for any adverse event after each injection (ORs: 2.942 and 2.818), as well as female sex for those mild (ORs: 1.856 and 2.818) and common (ORs: 3.452 and 2.145). Findings were consistent with national reports as most of the adverse events were mild and associated with female sex and young age, while investigations are needed for reactions not described elsewhere. Data are useful to support the vaccine safety profile, also because largely targeted healthcare personnel more skilled than general population in self-diagnosis of health-related issues.

Introduction: Exercise is known to improve cognitive functioning and the cardiorespiratory hypothesis suggests that this is due to the relationship between cardiorespiratory fitness (CRF) level and cerebral oxygenation. The purpose of this systematic review is to consolidate findings from functional near-infrared spectroscopy (fNIRS) studies that examined the effect of CRF level on cerebral oxygenation during exercise and cognitive tasks. Methods: Medline, Embase, SPORTDiscus, and Web of Science were systematically searched. Studies categorizing CRF level using direct or estimated measures of VO 2max and studies measuring cerebral oxygenation using oxyhemoglobin ([HbO2]) and deoxyhemoglobin ([HHb]) were included. Healthy young, middle-aged, and older adults were included whereas patient populations and people with neurological disorders were excluded. Results: Following PRISMA guidelines, 14 studies were retained following abstract and full-text screening. Cycle ergometer or treadmill tests were used as direct measures of CRF, and one study provided an estimated value using a questionnaire. Seven studies examined the effects of CRF on cerebral oxygenation during exercise and the remaining seven evaluated it during cognitive tasks. Increased [HbO2] in the prefrontal cortex (PFC) was observed during cognitive tasks in higher compared to lower fit individuals. Only one study demonstrated increased [HHb] in the higher fit group. Exercise at submaximal intensities revealed increased [HbO2] in the PFC in higher compared to lower fit groups. Greater PFC [HHb] was also observed in long- vs. short-term trained males but not in females. Primary motor cortex (M1) activation did not differ between groups during a static handgrip test but [HHb] increased beyond maximal intensity in a lower compared to higher fit group. Conclusion: Consistent with the cardiorespiratory hypothesis, higher fit young, middleaged, and older adults demonstrated increased cerebral oxygenation compared to lower fit groups. Future research should implement randomized controlled trials to evaluate the effectiveness of interventions that improve CRF and cerebral oxygenation longitudinally [ABSTRACT FROM AUTHOR]

High impact chronic pain (HICP) is a recently proposed concept for treatment stratifying patients with chronic pain and monitoring their progress. The goal is to reduce the impact of chronic pain on the individual, their family, and society. The US National Pain Strategy defined HICP as the chronic pain associated with substantial restrictions on participation in work, social, and self-care activities for at least 6 months. To understand the meaning and characteristics of HICP from the younger (

IntroductionExercise is known to improve cognitive functioning and the cardiorespiratory hypothesis suggests that this is due to the relationship between cardiorespiratory fitness (CRF) level and cerebral oxygenation. The purpose of this systematic review is to consolidate findings from functional near-infrared spectroscopy (fNIRS) studies that examined the effect of CRF level on cerebral oxygenation during exercise and cognitive tasks.MethodsMedline, Embase, SPORTDiscus, and Web of Science were systematically searched. Studies categorizing CRF level using direct or estimated measures of V̇O2max and studies measuring cerebral oxygenation using oxyhemoglobin ([HbO2]) and deoxyhemoglobin ([HHb]) were included. Healthy young, middle-aged, and older adults were included whereas patient populations and people with neurological disorders were excluded.ResultsFollowing PRISMA guidelines, 14 studies were retained following abstract and full-text screening. Cycle ergometer or treadmill tests were used as direct measures of CRF, and one study provided an estimated value using a questionnaire. Seven studies examined the effects of CRF on cerebral oxygenation during exercise and the remaining seven evaluated it during cognitive tasks. Increased [HbO2] in the prefrontal cortex (PFC) was observed during cognitive tasks in higher compared to lower fit individuals. Only one study demonstrated increased [HHb] in the higher fit group. Exercise at submaximal intensities revealed increased [HbO2] in the PFC in higher compared to lower fit groups. Greater PFC [HHb] was also observed in long- vs. short-term trained males but not in females. Primary motor cortex (M1) activation did not differ between groups during a static handgrip test but [HHb] increased beyond maximal intensity in a lower compared to higher fit group.ConclusionConsistent with the cardiorespiratory hypothesis, higher fit young, middle-aged, and older adults demonstrated increased cerebral oxygenation compared to lower fit groups. Future research should implement randomized controlled trials to evaluate the effectiveness of interventions that improve CRF and cerebral oxygenation longitudinally.

To determine if preoperative physical and psychological health risk factors are influential on physical function and satisfaction scores in a cohort of relatively younger adults one year post-total knee arthroplasty. Sixty-five patients were recruited pre- and one year post-total knee arthroplasty. Physical (i.e., body mass index, sex, physical activity level, number of comorbidities) and psychological (i.e., depression, expectations, pain inference) health risk factors were obtained pre-total knee arthroplasty and compared to Patient-Reported Outcomes Measurement Information System physical function computerized adaptive testing and satisfaction scores one year post-total knee arthroplasty. Bootstrap inclusion fraction methods were performed to compare the stability of each predictor variable prior to final regression analyzes. Poorer preoperative physical activity level (standardized regression coefficient = 0.37; p < 0.01), pain interference (standardized regression coefficient = –0.24; p = 0.03) and greater comorbidities (standardized regression coefficient = –0.27; p = 0.01) resulted in worse physical function scores one year post-total knee arthroplasty. Greater preoperative comorbidities (odds ratio = 0.63; p < 0.01) resulted in worse satisfaction scores one year post-total knee arthroplasty. No other predictor variable had any relationship on either clinical outcome (p > 0.05). Younger adults with greater comorbidities, lower physical activity level and higher pain interference scores preoperatively reported poorer functional recovery one year post-total knee arthroplasty. Understanding how preoperative status of younger adults undergoing total knee arthroplasty may lead to better improved surgical decision making and health care delivery for this vulnerable and growing patient subgroup. Projections estimate total knee arthroplasty in relatively younger adults (<65 years) will make up the majority of surgical procedures performed in the United States within the next two decades, however little is known in this patient population. This study provides evidence that relatively younger adults with greater comorbidities, lower physical activity level and higher pain interference scores preoperatively result in poorer functional recovery one year post-total knee arthroplasty. The results also suggest greater comorbidities identified preoperatively have the largest influence on one year satisfaction scores in younger adults post-total knee arthroplasty. Modifiable characteristics such as improving physical activity level, incorporating pain management strategies and reducing comorbidities preoperatively or adopting into postoperative rehabilitative care may influence the postoperative physical function and satisfaction scores in relatively younger adults undergoing total knee arthroplasty.

Objectives: Given the widely acknowledged benefits of intergenerational programs (IGPs), we compared processes and structures across different IGP types and explored potential areas for improvement.Design: Thirteen IGPs were classified into three types: arts, learning, and assistance programs. Data were collected through direct structured interviews and analyzed quantitatively and qualitatively.Setting: Participants were recruited from community-based IGPs in the greater Tel Aviv area of Israel.Participants: Eighty-four older participants (OPs), 97 younger participants (YPs), and 21 organizers were interviewed.Measurements: Questions included participant demographics as well as closed- and open-ended questions regarding processes based on the Impact of Intergenerational Programs Questionnaire (IIPQ).Analysis: Responses to closed-ended questions were compared among IGP types and age groups using two-way ANOVAs for ordinal data, and chi-squares for nominal data. Responses to open-ended questions by OP, YP, and program organizers about potential areas for improvement were analyzed using thematic analysis.Results: Processes in need of improvement were preparation and guidance, length of program participation, and monitoring of activities, which differed across IGP types and age groups. These processes were related to broader structural problems such as lack of resources, organizers' poor employment conditions, and inadequate public services for older persons in Israel.Conclusions: Our study highlights the complex relationships between IGP types, processes, and structures. IGP processes and goals can be hindered by structural variables such as insufficient funding, infrastructure, and public services for older adults. [ABSTRACT FROM AUTHOR]

PurposeAlthough cigarette smoking remains the most common risk factor for heart disease among the young, few studies have explored the relationship of smoking with heart disease mortality risk among young people. This prospective study assesses the risk and burden of all heart disease (HD) and coronary heart disease (CHD) mortality associated with smoking among younger adults from a nationally representative sample of the United States.MethodNational Health Interview Survey respondents' data from 1997-2004 were linked to their death records through 2006. The analyses were restricted to individuals 18 to 44 years of age during follow up (n = 121,284). Cox proportional hazard ratios (HR) were estimated with adjustment for sample weights and design effects. Attributable fractions (AF) of smoking were calculated.ResultsAfter controlling for age, race, body mass index, history of hypertension and diabetes, and leisure time physical activity, current smoking related CHD mortality HR was 14.6 [95 % confidence interval or CI, 3.3-64.9] for females and 3.6 [95 % CI, 1.2-10.4] for males. The HR for all HD mortality was 3.1 [95 % CI, 1.3-7.6] for females and 2.4 [95 % CI, 1.2-4.7] for males. The AF of smoking for CHD deaths for female and male were 0.58 and 0.54 respectively. The AF of all HD mortality was 0.31 for male and 0.32 for female. The mean estimates of all HD deaths attributable to smoking during 1997-2006 among this age group were 52,214, of which 45,147 were CHD deaths.ConclusionEven after adjustment for multiple risk factors and without addressing passive smoking, our result showed a strong relationship between smoking and HD and CHD mortality among young adults that is likely causal.

Background: The COVID-19 pandemic may lead to negative mental health effects but the effect on alcohol consumption among younger adults is unclear. We assess predictors of change in alcohol consumption during the first phase of the COVID-19 pandemic among younger adults.Methods: This cross-sectional internet-based survey was part of an overarching project, the Corona Drug Survey, which was conducted from April 30 to August 4, 2020. Participants of any sex and ≥18 years old were included. The primary outcome measure was change in alcohol consumption during the early COVID-19 pandemic. We implemented an ordinal logistic regression to assess the effect (odds ratio [OR] and 95% confidence interval [CI]) of the following predictors: quarantine restrictions on leaving the residence, number of individuals in the household, problematic alcohol consumption before the pandemic (CAGE [cutting down, annoyance by criticism, guilty feeling, and eye-opener] score), personal concern regarding the pandemic, age, and sex.Results: 3,321 participants with a mean age of 32 (SD: 13) years were included in this study. 70.4% of participants reported less or unchanged alcohol consumption in the recent 4 weeks of the pandemic compared to before the pandemic. A higher number of individuals in the household was associated with a reduced alcohol consumption (OR = 0.869; 95% CI = 0.815–0.927). No quarantine restrictions on leaving the residence (OR = 1.593; 95% CI = 1.397–1.817), a higher age (1.006; 1.001-1.011), and female sex (compared to males: 1.206; 1.062–1.371) were associated with an increase in alcohol consumption. The CAGE score before the pandemic (OR = 0.983; 95% CI = 0.931–1.037) and the pandemic concern (0.927; 0.857–1.003) were not associated with a significant change in alcohol consumption. Celebrations were no longer frequent drinking occasions during the pandemic compared to before the pandemic. The majority of participants (60.9%) did not use alcohol drinking as a coping mechanism to mitigate negative effects of the pandemic.Interpretation: In this cohort of younger adults with fewer celebratory drinking occasions, restrictions on leaving the residence and the number of persons in the household were the strongest predictors of reduced alcohol consumption during the early phase of the pandemic.

Introduction : Dual-task studies have demonstrated that walking is attention-demanding for younger adults. However, numerous studies have attributed this to task type rather than the amount of required to accomplish the task. This study examined four tasks: two discrete (i.e., short intervals of attention) and two continuous (i.e., sustained attention) to determine whether greater attentional demands result in greater dual-task costs due to an overloaded processing capacity. Methods : Nineteen young adults (21.5 ± 3.6 years, 13 females) completed simple reaction time (SRT) and go/no-go (GNG) discrete cognitive tasks and n-back (NBK) and double number sequence (DNS) continuous cognitive tasks with or without self-paced walking. Prefrontal cerebral hemodynamics were measured using functional near-infrared spectroscopy (fNIRS) and performance was measured using response time, accuracy, and gait speed. Results : Repeated measures ANOVAs revealed decreased accuracy with increasing cognitive demands (p = 0.001) and increased dual-task accuracy costs (p < 0.001). Response times were faster during the single compared to dual-tasks during the SRT (p = 0.005) and NBK (p = 0.004). DNS gait speed was also slower in the dual compared to single task (p < 0.001). Neural findings revealed marginally significant interactions between dual-task walking and walking alone in the DNS (p = 0.06) and dual -task walking compared to the NBK cognitive task alone (p = 0.05). Conclusion : Neural findings suggest a trend towards increased PFC activation during continuous tasks. Cognitive and motor measures revealed worse performance during the discrete compared to continuous tasks. Future studies should consider examining different attentional demands of motor tasks.

Introduction: Poor sleep is linked to impaired cognitive function, cortical brain atrophy, and lower cortical thickness. Independently, higher cardiovascular endurance has neuroprotective effects. It remains in question, however, whether cardiovascular endurance moderates the relationship between sleep and brain health. The aims of this study included the following: 1) the association between subjective sleep quality and cognitive performance, hippocampus volume, and entorhinal cortex (EC) thickness, and 2) the moderating effects of cardiovascular endurance on the associations of sleep quality with cognitive and magnetic resonance imaging measures in healthy younger adults. Methods: A total of 1095 younger adults (28.8 ± 3.6 yr) from the Human Connectome Project were included in the analyses. The 2-min walk test was used as a proxy of cardiovascular endurance. Self-reported sleep quality was measured using the Pittsburgh Sleep Quality Index. Composite cognitive tests were used to assess global cognition, and T1-weighted structural magnetic resonance imaging data (obtained using Siemens 3T scanner) was used to assess hippocampus volume and EC thickness. Linear regression was used to examine the moderating effects of fitness on the relationships between sleep and each of these neurocognitive outcomes after controlling for age, sex, and education year. Results: Poorer sleep quality was associated with both a lower crystalized intelligence score (B = -0.198, P = 0.034) and lower EC thickness (B = -0.013, P = 0.003). With greater 2-min walk test score, the association between greater Pittsburgh Sleep Quality Index score and lower EC thickness was attenuated (B = 0.0008, P = 0.028). Conclusions: Higher cardiovascular endurance may mitigate the relationship between poorer subjective sleep quality and lower EC thickness. Future longitudinal studies should examine the interactive effects of sleep and fitness on brain health among older and more vulnerable populations. [ABSTRACT FROM AUTHOR]

Abstract Background Lung adenocarcinoma in young adults is a rare entity with the oncogenic genetic alterations associated being poorly understood. In the present study, the effect of genetic alterations in lung adenocarcinoma patients diagnosed in young patients is reported. Methods Twenty young lung adenocarcinoma patients (age years: median: 33.5, range: 24‐36) were enrolled in the current study and 24 patients who were at common age of the disease onset (age years: median: 61.5, range: 52‐79) were selected for comparison. Paraffin sections of lung adenocarcinoma were analyzed using the whole‐exome sequencing platform. Results Similar number of somatic mutations per tumor were found in the young patients and their older counterparts. Although no age‐related differences were detected in the numbers of lung adenocarcinoma patients harboring well‐known gene variants, mutations in FRG1 and KMT2C were associated with a younger age especially after correcting for tobacco smoking and sex (FRG1: P = 0.027, KMT2C: P = 0.046). Five genetic variants showed higher alteration frequencies in young patients compared to the unclassified East Asian population, suggesting these mutations as disease‐related hereditary germline variants. Conclusions These results suggest different characteristics of lung adenocarcinoma between the young and the patients at common age of onset. Young patients with lung adenocarcinoma have a distinctly unique prevalence of oncogenic genetic alterations.

Background: Arthroscopic superior capsular reconstruction (ASCR) is a method for treating irreparable chronic rotator cuff tears. However, the extent to which ASCR can be performed with regard to the patient's age has yet to be determined. Purpose: To compare the surgical outcomes of ASCR for the treatment of irreparable rotator cuff tears (IRCTs) in patients aged <65 years versus patients aged ≥65 years. Study Design: Cohort study; Level of evidence, 3. Methods: Of 105 patients with IRCTs who underwent ASCR between March 2013 and June 2020, 73 patients were enrolled in this study based on the selection criteria. Polypropylene mesh augmentation to the graft was used in 18 of 36 patients in the younger adults group (age, <65 years) and 20 of 37 patients in the older adults group (age, ≥65 years). The clinical and radiological outcomes were evaluated preoperatively and at the final clinical follow-up. The graft integrity status was evaluated using serial magnetic resonance imaging and set as the primary endpoint. Furthermore, subgroup analysis was performed based on age group and graft type. Results: The mean age of the patients was 59.2 ± 3.8 years in the younger adults group and 70.5 ± 4.1 years in the older adults group. Both groups showed improvement based on the clinical and radiological outcomes at the final follow-up. The mean American Shoulder and Elbow Surgeons scores improved from 52.3 ± 15.4 to 77.3 ± 13.5 in the younger adults group (P <.001) and from 45.7 ± 16.1 to 76.6 ± 11.4 in the older adults group (P <.001). The mean visual analog scale for pain scores improved from 5.5 ± 1.2 to 2.1 ± 0.9 in the younger adults group (P <.001) and from 5.5 ± 1.4 to 2.1 ± 1.2 in the older adults group (P <.001). The graft healing rate was significantly higher in the younger adults group (81%) than in the older adults group (65%) (P =.049). Subgroup analysis showed that after mesh augmentation, the healing rate in the younger adults group (84%) was similar to that in the older adults group (85%) (P =.299). Conclusion: ASCR resulted in a favorable surgical outcome for both younger and older adult patients with IRCT. The younger patients had lower graft failure rates and superior surgical outcomes. In older patients, ASCR using polypropylene mesh augmentation may reduce graft failure and result in surgical outcomes similar to those in younger patients. [ABSTRACT FROM AUTHOR]

Background: The oral squamous cell carcinoma (OSCC) often affects elderly aged adults, who had long-term tobacco exposure. In the recent past decade, there is an increasing incidence of OSCC in younger individuals, who had less tobacco association. Aim: The aim of this study is to examine the risk factors and to assess and compare the clinicopathological features and prognosis of OSCC in young patients with the older group patients. Materials and Methods: We included studies that addressed the OSCC involving young patients during the period between 2014 and 2019. Initially, we found 679 articles; after refined evaluation, 92 works had their titles matching to the present work. After extraction of case reports, reviews, and studies with un-matched objectives or inadequate data, we have chosen only 24 presentations matching to the abstract. The statistical analysis performed by Chi-square tests using SPSS 20.0 version for windows. Results: Of the total OSCC, 10% of patients belonged to the younger age group, and 90% were the older aged group. Both the groups showed male gender predominance and tongue as the predominant site of involvement. The younger patients tend to have significantly reduced tobacco exposure. The highly reported tumors were advanced staged and moderately differentiated tumors in both groups. There was a statistically evident high recurrence reported in the younger group. The overall survival seems to be similar for both groups. Conclusion: The identification of the potential risk factors, along with unique molecular mechanisms, and biological behavior of the disease is mandatory to control the incidence of OSCC in young adults.

The present experiment studied the influence of simultaneous matching-to-sample (SMTS) or delayed matching-to-sample (DMTS 0 s) using the many-to-one (MTO) or one-to-many (OTM) training structures on the formation of equivalence classes in older and younger adults. Sixty older adults and 16 younger adults were divided into four groups: (1) SMTS-MTO, (2) SMTS-OTM, (3) DMTS 0 s-MTO, and (4) DMTS 0 s-OTM. All of the younger adults established conditional discriminations, whereas only 35 of the 60 older adults did the same. The SMTS-OTM had the lowest number of trials to mastery criterion for the older adults, and the SMTS-MTO group had the highest number of participants forming equivalence classes. In the younger adults, the differences in trials to mastery criterion were minimal, and there were no differences in the equivalence tests across groups. The older adults had a higher reaction time to comparison stimuli than the younger adults. [ABSTRACT FROM AUTHOR]

Abstract Background Although there are moderating effects of race on blood pressure (BP) and brain health in older adults, it is currently unknown if these race‐related differences in cardiovascular and associated brain function are also present in younger adults. The purpose of this study was to investigate the interaction between race and BP on brain health in younger African (AA) and Caucasian Americans (CA). Methods We studied 971 younger adults (29.1 ± 3.5 years; 180 AAs and 791 CAs) who volunteered to participate in the Human Connectome Project. Cognitive composite scores, brain volume, and cortical thickness using MRI were cross‐sectionally assessed. ANCOVA was used to examine interactions between race and mean arterial pressure (MAP) on cognitive test scores and brain structure. Results After controlling for age, sex, education, and BMI, there were significant Race × MAP interaction effects on cognitive composite scores and cortical thickness. Among AAs but not CAs, as MAP increased, both global cognitive performance and entorhinal cortex (ERC) thickness decreased. Conclusions MAP was an important moderator of racial differences in cognitive performance and ERC thickness. Our findings suggest that young AAs may carry a greater hypertension‐associated risk for cognitive brain health deficit. Interventions that address early signs of hypertension in AAs are needed to determine if the racial disparities in BP‐related brain health in late adulthood can be reduced.

The degree of being conscious about privacy for the self and others is known as privacy consciousness. This study aimed to compare privacy consciousness between younger and older adults. Japanese younger (n = 166) and older (n = 145) adults were requested to rate all items in the Privacy Consciousness Scale, which assessed their degree of consciousness about privacy for the self and others and behaviors for maintaining privacy based on this consciousness. Results indicated that older adults scored lower on Consciousness Regarding Privacy of Others and higher on Behaviors Regarding Privacy of Others than younger adults. However, no significant difference was found in Consciousness and Behaviors Regarding Privacy of the Self between younger and older adults. [ABSTRACT FROM AUTHOR]

Background The Food Insecurity Experience Scale (FIES) is a UN FAO Voices of the Hungry (FAO-VoH) experiential metric of food insecurity (FI). It was pilot tested in some countries but not in Arab speaking ones and validated using global data. Yet, its psychometric properties may vary in the League of Arab States (LAS) due to cultural and linguistic differences. Objectives 1) assess the validity of FIES for use in the LAS region, 2) determine the prevalence of FI, by gender, age group, and the human development index (HDI), and 3) examine sociodemographic characteristics of severe FI individuals. Methods To assess the psychometric properties of FIES, Rasch modeling was applied to the 2014–2015 Gallop World Poll (GWP) in the LAS. Prevalence and characteristics of severely FI individuals were assessed using the 2014–2017 GWP data of 62,261 respondents. Results Overall, FIES met the Rasch model assumptions of equal discrimination and conditional independence. Infit statistics for FIES items, in most LAS countries, were <1.3, indicating good internal validity. In Syria and Sudan, the item "worried about not having enough food to eat" had infits >1.3. Outfit statistics >2.0, indicating erratic responses, were noted in 26% of the LAS countries. Significant correlations were found (≥0.4) between items in Algeria, Tunisia, and Lebanon. The overall prevalence of severe FI was 15.7%. At highest risk were those aged ≥50 y compared with younger adults (16.5% versus 15.5%, respectively, P  <0.02), women compared with men (17.6% versus 14.1%, respectively, P  <0.0001), and those in countries with low HDI compared with high HDI (24.9% versus 8.3%, respectively, P  <0.0001). Conclusions Overall, FIES is valid for measuring FI in the LAS. Cognitive testing of items with high outfit statistics and omission of correlated ones may improve the scale. Populations vulnerable to severe FI include older adults and women. These populations should be examined further. [ABSTRACT FROM AUTHOR]

Background: The incidence of colorectal cancer (CRC) in younger adults (<50 years old) is rising worldwide, at a rate of 1% per annum since mid‐1980s. The clinical concern is that younger adults may have more advanced disease leading to poorer prognosis compared to their older cohort due to lack of screening. Therefore, the aim of this study is to assess the incidence and short‐term outcomes of colorectal cancer in younger adults. Methods: This is a retrospective study from a prospectively maintained bi‐national database from 2007 to 2018. Results: There were 1540 younger adults diagnosed with CRC, with a rise from 5.8% in 2007 to 8.4% in 2018. Majority had lower American Society of Anaesthesiologists (ASA) scores (89%), rectal cancers (46.1%) and higher tumour stage (65.4%). As a consequence, they were likely to have higher circumferential resection margin positivity (6%, P = 0.02) and to receive adjuvant chemotherapy (57.1%, P < 0.001) compared to their older cohort. Multivariate analysis showed disadvantaged socioeconomic status (odds ratio (OR) 3.3, 95% confidence interval (CI) 1.37–7.94, P < 0.001) and increasing tumour stage (OR 14.9, 95% CI 1.89–116.9, P < 0.001) were independent predictors for circumferential resection margin positivity whereas being female (OR 0.71, 95% CI 0.53–0.95, P = 0.02), higher ASA score (OR 175.3, 95% CI 26.7–1035.5, P < 0.001), urgent surgery (OR 2.75, 95% CI 1.84–4.11, P < 0.001) and anastomotic leak (OR 5.02, 95% CI 3.32–7.58, P < 0.001) were predictors of inpatient mortality. Conclusion: There is a steady rise in the incidence of colorectal cancer in younger adults. Both physicians and younger adults should be aware of the potential risk of colorectal cancer (CRC) and appropriate investigations performed so not to delay the diagnosis. [ABSTRACT FROM AUTHOR]

There is mixed evidence on the impact of delay task difficulty on prospective memory (PM) performance and little research has examined this among older adults. The present study examined younger (N = 60) and older (N = 57) adults' prospective memory (PM) performance after completing an easy or difficult Raven's matrices task. To assess whether delay difficulty impacted how often participants thought about their PM intention, participants were asked to report on what they thought about during the delay task itself and retrospectively after all tasks were completed. Younger adults outperformed older adults on the PM task; however, delay task difficulty had no impact PM for either age group. Reports of thinking about the intention during the delay task differed by age group depending whether they were online or retrospective, however, overall greater reports of thinking about the intention was positively associated with PM performance.
