OBJECTIVE: Chemoradiation followed by esophagectomy is a standard treatment option for locally advanced esophageal cancer (LAEC) patients. Esophagectomy is a high-risk procedure, and recent evidence suggests select patients may benefit from omitting or delaying surgery. This study aims to compare surgery versus active surveillance for LAEC patients with complete clinical response (cCR) after neoadjuvant chemoradiotherapy (nCRT). METHODS: Decision analysis with Markov modelling was utilized...

The percentage of U.S. residents 65 years and older was 17% in 2020, and this number is expected to rise due to the aging of the baby boomer generation.1Although life expectancy fell between 2020 and 2021, the proportion of U.S. residents older than 65 years continues to increase.2This age group often has more medical comorbidities and prescription medications, increasing the demand for primary care access. Domestic migration (U.S. residents moving within the country) of this retirement-aged population further strains the primary care workforce in underserved areas...

Water is an indispensable material for human life. Unfortunately, the development of industrial activities has reduced the quality of water resources in the world. Meantime, heavy metals are an important factor in water pollution due to their toxicity. This study highlights the method for the capture of heavy metal ions from wastewater using the procedure of adsorption. The adsorption of toxic heavy metal ions (Pb2+ , Hg2+ , and Cd2+ ) on Ca2 C as well as Cr2 C carbide-nitride MXene monolayers is investigated using the density functional theory...

BACKGROUND AND OBJECTIVES: Understanding trends in the use of medications for secondary stroke prevention is crucial for identifying areas for improvement in stroke care. We examined the use of lipid-lowering, antihypertensive, glucose-lowering, oral anticoagulant, and antiplatelet medications after ischemic stroke hospitalization, from 2005 to 2021. METHODS: Using nationwide registries in Denmark, we identified a cohort of patients discharged from hospital with a first-time or recurrent ischemic stroke (N = 150,744)...

Older adults experienced major changes during the COVID-19 pandemic and ensuing restrictions, and it might be expected that those who were already socially isolated before the pandemic were particularly vulnerable. We apply an outcome-wide longitudinal design on 4,636 participants (mean age 66.8 y) from the English Longitudinal Study of Ageing, observed in 2018/19 and early (June/July 2020) and later (November/December 2020) in the pandemic. Social isolation is defined using an index including marital status, social contact, and social participation in 2018/19...

Age is an important risk factor for both glaucoma and cataract. As global life expectancy continues to rise, the prevalence of concomitant open-angle glaucoma (OAG) and cataracts is increasing. Currently, there is a lack of definitive consensus on the optimal management approach for such individuals. Conventionally, trabeculectomy (Trab) in combination with phacoemulsification is the preferred method. Recent developments in microinvasive glaucoma surgery (MIGS), which offer similar results with fewer complications, provide a new possible approach to this condition...

Flagellar motility is a key bacterial trait as it allows bacteria to navigate their immediate surroundings. Not all bacteria are capable of flagellar motility, and the distribution of this trait, its ecological associations, and the life history strategies of flagellated taxa remain poorly characterized. We developed and validated a genome-based approach to infer the potential for flagellar motility across 12 bacterial phyla (26 192 genomes in total). The capacity for flagellar motility was associated with a higher prevalence of genes for carbohydrate metabolism and higher maximum potential growth rates, suggesting that flagellar motility is more prevalent in environments with higher carbon availability...

"At what age would you describe someone as old?" Perceptions of when old age begins might be prone to upward shifts because of historical increases in life expectancy and in retirement age, as well as because of better psychosocial functioning in later life. We investigated historical changes in within-person trajectories of the perceived onset of old age using data from 14,056 participants who entered the German Ageing Survey at age 40-85 years and who completed up to eight assessments across 25 years. Using longitudinal multilevel regression models, we found that at age 64, the average perceived onset of old age is at about age 75 years...

The Y chromosome has recognized functions in promoting male sex determination and regulating aspects of fertility. However, recent work has demonstrated important roles for the Y chromosome and Y-encoded genes in multiple domains of male health, including cancer. It is well-established that males experience shorter life spans than females, and this sex bias on overall mortality is ac-centuated in populations with longer life expectancy, in part related to elevated rates of cancer. The majority of human malignancies exhibit a sex bias with elevated frequencies in males...

OBJECTIVE: With an increasing life expectancy, more octogenarian patients are referred with complex aortic aneurysms (cAAA). The aim of this study was to evaluate short and mid-term outcomes following fenestrated aortic repair (FEVAR) in octogenarians. SUMMARY BACKGROUND DATA: Few studies looking at octogenarian-specific outcomes with diverging results. METHODS: Retrospective, multicentre cohort study including consecutive patients undergoing elective FEVAR for cAAAs or type IV thoracoabdominal aortic aneurysms between 2007-2022 in eight high-volume centres...

BACKGROUND: The chronic, inflammatory skin disease hidradenitis suppurativa (HS) (prevalence: 0.5%-1%, diagnostic delay: 7-10 years) primarily arises in younger adults and frequently coincides with autoimmune comorbidities and unhealthy life-styles (smoking and obesity). These factors are known to increase cancer risk, but despite this, information on cancer occurrence among HS patients is scarce. MATERIALS AND METHODS: A nationwide retrospective register-based study assessing relative risk of cancer - overall and by anatomical site - following HS diagnosis expressed as standardized incidence ratios (SIRs), which is ratios between observed cases among all Danes diagnosed with HS since 1977 and expected cases based on cancer incidence rates of the entire Danish population during the same period...

Community health workers (CHWs) are increasingly being required to perform complex health care activities, especially in community cardiovascular disease and stroke prevention. However, currently, there are no psychometrically validated instruments for assessing CHW competencies in these roles. This article describes the development and validation of the stroke literacy assessment test (SLAT)-pertaining to the Life's Simple Seven (LS7) risk factors for stroke-for evaluating CHWs' competencies in the context of education and training programs...

By supporting autonomy, aging in place, and wellbeing in later life, Socially Assistive Robots are expected to help humanity face the challenges posed by the rapid aging of the world's population. For the successful acceptance and assimilation of SARs by older adults, it is necessary to understand the factors affecting their Quality Evaluations Previous studies examining Human-Robot Interaction in later life indicated that three aspects shape older adults' overall QEs of robots: uses, constraints, and outcomes...

Patients with long-standing autoimmune diseases like systemic lupus erythematosus (SLE) are at a higher risk of developing hematological malignancies. However, chronic myeloid leukemia (CML) has rarely been reported in patients with SLE. Advancements in medical diagnostics and treatment have led to the life expectancy of SLE and CML patients moving closer to that of the general population, and it is not uncommon to encounter more than one malignancy in a cancer survivor. Although squamous cell carcinoma (SCC) of the skin has been reported in CML patients, mucosal SCC of the head and neck has rarely only been reported in CML survivors...

BACKGROUND: As the surgical burden grows, increasing patient safety during anesthesia and surgery becomes a major global public health priority. Anesthesia can be safely administered in higher-income countries, yet it is more challenging in third-world countries. This study focuses on Sudan, a third-world country, and its unmet anesthetic needs before the current war and how these needs might compromise the post-war status. AIM: The aim of this study is to compare Sudan's outstanding anesthesia requirements to the World Health Organization's safe anesthesia practice standards in terms of workforce, medications, equipment, and anesthesia conduct...

BACKGROUND: To describe the past, present and future burden of pancreatitis in older adults, and to explore cross-national inequalities across socio-demographic index (SDI). METHODS: Data on pancreatitis in older adults, including mortality and disability-adjusted life years (DALYs) rates, were collected from the Global Burden of Disease (GBD) 2019 study. Temporal trends were measured using joinpoint analyses and predicted using a Bayesian age-period-cohort model...

Over the past 15 years, the output power of silicon submillimeter-wave electronics has increased by a factor greater than 1000 reaching -3.9 dBm at 440 GHz for a single unit in CMOS and -10.7 dBm at 1.01 THz for a 42-element array in SiGe BiCMOS. The smallest power of a 1 kHz bandwidth signal at 420 GHz that can be detected has improved by 100 million times. These and the expected improvements from the ongoing activities should be sufficient to support high resolution imaging with a range of up to several hundred meters, gas sensing up to ∼1 THz, and communication over ∼1000 m...

INTRODUCTION: The population of older adults is growing disproportionately, constituting 13% of the global population in 2022, and is expected to double by 2050. One of public health's priorities is healthy aging, the maintenance of functional ability aligned with well-being. As many as 50% of older adults report poor sleep quality, leading to an increased risk of morbidity and mortality. The quality and quantity of social relationships may broadly benefit sleep in older adults. However, the concept of socially-supported sleep is underdeveloped as a basis for intervention...

BACKGROUND: Patients with schizophrenia have substantial comorbidity that contributes to reduced life expectancy of 10 to 20 years. Identifying modifiable comorbidities could improve rates of premature mortality. Conditions that frequently co-occur but lack shared genetic risk with schizophrenia are more likely to be products of treatment, behavior, or environmental factors and therefore are enriched for potentially modifiable associations. METHODS: Phenome-wide comorbidity was calculated from electronic health records of 250,000 patients across 2 independent health care institutions (Vanderbilt University Medical Center and Mass General Brigham); associations with schizophrenia polygenic risk scores were calculated across the same phenotypes in linked biobanks...

BACKGROUND: Homelessness is a traumatic experience, and can have a devastating effect on those experiencing it. People who are homeless often face significant barriers when accessing public services, and have often experienced adverse childhood events, extreme social disadvantage, physical, emotional and sexual abuse, neglect, low self-esteem, poor physical and mental health, and much lower life expectancy compared to the general population. Rates of problematic substance use are disproportionately high, with many using drugs and alcohol to deal with the stress of living on the street, to keep warm, or to block out memories of previous abuse or trauma...
