ABSTRACT
BACKGROUND: Older adults with cognitive impairment exhibit different patterns of healthcare utilization compared to their cognitively healthy counterparts. Despite extensive research in high-income countries, similar studies in low- and middle-income countries are lacking. This study aims to investigate the population-level patterns in healthcare utilization among older adults with and without cognitive impairment in Mexico. METHODS: Data came from five waves (2001-2018) of the Mexican Health and Aging Study. We used self-reported measures for one or more over-night hospital stays, doctor visits, visits to homeopathic doctors, and dental visits in the past year; seeing a pharmacist in the past year; and being screened for cholesterol, diabetes, and hypertension in the past two years. Cognitive impairment was defined using a modified version of the Cross Cultural Cognitive Examination that assessed verbal memory, visuospatial and visual scanning. Total sample included 5,673 participants with cognitive impairment and 34,497 without cognitive impairment interviewed between 2001 and 2018. Generalized Estimating Equation models that adjusted for time-varying demographic and health characteristics and included an interaction term between time and cognitive status were used. RESULTS: For all participants, the risk for one or more overnight hospital stays, doctor visits, and dental visits in the past year, and being screened for diabetes, hypertension, and high cholesterol increased from 2001 to 2012 and leveled off or decreased in 2015 and 2018. Conversely, seeing a homeopathic doctor decreased. Cognitive impairment was associated with higher risk of hospitalization (RR = 1.13, 1.03-1.23) but lower risk of outpatient services (RR = 0.95, 0.93-0.97), cholesterol screening (RR = 0.93, 0.91-0.96), and diabetes screening (RR = 0.95, 0.92-0.97). No significant difference was observed in the use of pharmacists, homeopathic doctors, or folk healers based on cognitive status. Interaction effects indicated participants with cognitive impairment had lower risk for dental visits and hypertension screening but that these trajectories differed over time compared to participants without cognitive impairment. CONCLUSIONS: We identified distinct population-level trends in self-reported healthcare utilization and differences according to cognitive status, particularly for elective and screening services. These findings highlight the necessity for policy interventions to ensure older adults with cognitive impairment have their healthcare needs met.

BACKGROUND: Chronological age (CA) is an imperfect proxy for the true biological aging state of the body. As novel measures of biological aging, Phenotypic age (PhenoAge) and Phenotypic age acceleration (PhenoAgeAccel), have been shown to identify morbidity and mortality risks in the general population. HYPOTHESIS: PhenoAge and PhenoAgeAccel might be associated with mortality in heart failure (HF) patients. METHODS: This cohort study extracted adult data from the National Health and Nutrition Examination Survey (NHANES) databases. Weighted univariable and multivariable Cox models were performed to analyze the effect of PhenoAge and PhenoAgeAccel on all-cause mortality in HF patients, and hazard ratio (HR) with 95% confidence intervals (CI) was calculated. RESULTS: In total, 845 HF patients were identified, with 626 all-cause mortality patients. The findings suggested that (1) each 1- and 10-year increase in PhenoAge were associated with a 3% (HR = 1.03, 95% CI: 1.03-1.04) and 41% (HR = 1.41, 95% CI: 1.29-1.54) increased risk of all-cause mortality, respectively; (2) when the PhenoAgeAccel < 0 as reference, the ≥ 0 group was associated with higher risk of all-cause mortality (HR = 1.91, 95% CI = 1.49-2.45). Subgroup analyses showed that (1) older PhenoAge was associated with an increased risk of all-cause mortality in all subgroups; (2) when the PhenoAgeAccel < 0 as a reference, PhenoAgeAccel ≥ 0 was associated with a higher risk of all-cause mortality in all subgroups. CONCLUSION: Older PhenoAge was associated with an increased risk of all-cause mortality in HF patients. PhenoAge and PhenoAgeAccel can be used as convenient tools to facilitate the identification of at-risk individuals with HF and the evaluation of intervention efficacy.

Final annual mortality data from the National Vital Statistics System for a given year are typically released 11 months after the end of the calendar year. Provisional data, which are based on preliminary death certificate data, provide an early estimate of deaths before the release of final data. In 2023, a provisional total of 3,090,582 deaths occurred in the United States. The age-adjusted death rate per 100,000 population was 884.2 among males and 632.8 among females; the overall rate, 750.4, was 6.1% lower than in 2022 (798.8). The overall rate decreased for all age groups. Overall age-adjusted death rates in 2023 were lowest among non-Hispanic multiracial (352.1) and highest among non-Hispanic Black or African American persons (924.3). The leading causes of death were heart disease, cancer, and unintentional injury. The number of deaths from COVID-19 (76,446) was 68.9% lower than in 2022 (245,614). Provisional death estimates provide an early signal about shifts in mortality trends. Timely and actionable data can guide public health policies and interventions for populations experiencing higher mortality.

Economic welfare is essential in the modern economy since it directly reflects the standard of living, distribution of resources, and general social satisfaction, which influences individual and social well-being. This study aims to explore the relationship between national income accounting different attributes and the economic welfare in Pakistan. However, this study used data from 1950 to 2022, and data was downloaded from the World Bank data portal. Regression analysis is used to investigate the relationship between them and is very effective in measuring the relationship between endogenous and exogenous variables. Moreover, generalized methods of movement (GMM) are used as the robustness of the regression. Our results show that foreign direct investment outflow, Gross domestic product growth rate, GDP per capita, higher Interest, market capitalization, and population growth have a significant negative on the unemployment rate, indicating the rise in these factors leads to a decrease in the employment rate in Pakistan. Trade and savings have a significant positive impact on the unemployment rate, indicating the rise in these factors leads to an increase in the unemployment rate for various reasons. Moreover, all the factors of national income accounting have a significant positive relationship with life expectancy, indicating that an increase in these factors leads to an increase in economic welfare and life expectancy due to better health facilities, many resources, and correct economic policies. However, foreign direct investment, inflation rate, lending interest rate, and population growth have significant positive effects on age dependency, indicating these factors increase the age dependency. Moreover, GDP growth and GDP per capita negatively impact age dependency. Similarly, all the national income accounting factors have a significant negative relationship with legal rights that leads to decreased legal rights. Moreover, due to better health facilities and health planning, there is a negative significant relationship between national income accounting attributes and motility rate among children. Our study advocated the implications for the policymakers and the government to make policies for the welfare and increase the social factors.

Unlabelled: The integration of health and activity data from various wearable devices into research studies presents technical and operational challenges. The Awesome Data Acquisition Method (ADAM) is a versatile, web-based system that was designed for integrating data from various sources and managing a large-scale multiphase research study. As a data collecting system, ADAM allows real-time data collection from wearable devices through the device's application programmable interface and the mobile app's adaptive real-time questionnaires. As a clinical trial management system, ADAM integrates clinical trial management processes and efficiently supports recruitment, screening, randomization, data tracking, data reporting, and data analysis during the entire research study process. We used a behavioral weight-loss intervention study (SMARTER trial) as a test case to evaluate the ADAM system. SMARTER was a randomized controlled trial that screened 1741 participants and enrolled 502 adults. As a result, the ADAM system was efficiently and successfully deployed to organize and manage the SMARTER trial. Moreover, with its versatile integration capability, the ADAM system made the necessary switch to fully remote assessments and tracking that are performed seamlessly and promptly when the COVID-19 pandemic ceased in-person contact. The remote-native features afforded by the ADAM system minimized the effects of the COVID-19 lockdown on the SMARTER trial. The success of SMARTER proved the comprehensiveness and efficiency of the ADAM system. Moreover, ADAM was designed to be generalizable and scalable to fit other studies with minimal editing, redevelopment, and customization. The ADAM system can benefit various behavioral interventions and different populations.

Cancer remains a significant risk to human health. Nanomedicine is a new multidisciplinary field that is garnering a lot of interest and investigation. Nanomedicine shows great potential for cancer diagnosis and treatment. Specifically engineered nanoparticles can be employed as contrast agents in cancer diagnostics to enable high sensitivity and high-resolution tumor detection by imaging examinations. Novel approaches for tumor labeling and detection are also made possible by the use of nanoprobes and nanobiosensors. The achievement of targeted medication delivery in cancer therapy can be accomplished through the rational design and manufacture of nanodrug carriers. Nanoparticles have the capability to effectively transport medications or gene fragments to tumor tissues via passive or active targeting processes, thus enhancing treatment outcomes while minimizing harm to healthy tissues. Simultaneously, nanoparticles can be employed in the context of radiation sensitization and photothermal therapy to enhance the therapeutic efficacy of malignant tumors. This review presents a literature overview and summary of how nanotechnology is used in the diagnosis and treatment of malignant tumors. According to oncological diseases originating from different systems of the body and combining the pathophysiological features of cancers at different sites, we review the most recent developments in nanotechnology applications. Finally, we briefly discuss the prospects and challenges of nanotechnology in cancer.

BACKGROUND: Cervical and breast cancers are among the top 4 leading causes of cancer-related mortality in women. This study aimed to examine age-specific temporal trends in mortality for cervical and breast cancers in urban and rural areas of China from 2009 to 2021. METHODS: Age-specific mortality data for cervical and breast cancers among Chinese women aged 20-84 years were obtained from China's National Disease Surveillance Points system spanning the years 2009 to 2021. Negative binomial regression models were utilized to assess urban-rural differences in mortality rate ratios, while Joinpoint models with estimated average annual percent changes (AAPC) and slopes were employed to compare temporal trends and the acceleration of mortality rates within different age groups. RESULTS: From 2009 to 2021, there was a relative increase in age-specific mortality associated with the two cancers observed in rural areas compared with urban areas. A rising trend in the screening age of 35-64 [AAPC: 4.0%, 95% confidence interval (CI) 0.5-7.6%, P = 0.026] for cervical cancer was noted in rural areas, while a stable trend (AAPC: - 0.7%, 95% CI - 5.8 to 4.6%, P = 0.78) was observed in urban areas. As for breast cancer, a stable trend (AAPC: 0.3%, 95% CI - 0.3 to 0.9%, P = 0.28) was observed in rural areas compared to a decreasing trend (AAPC: - 2.7%, 95% CI - 4.6 to - 0.7%, P = 0.007) in urban areas. Urban-rural differences in mortality rates increased over time for cervical cancer but decreased for breast cancer. Mortality trends for both cervical and breast cancers showed an increase with age across 4 segments, with the most significant surge in mortality observed among the 35-54 age group across urban and rural areas, periods, and regions in China. CONCLUSIONS: Special attention should be given to women aged 35-54 years due to mortality trends and rural-urban disparities. Focusing on vulnerable age groups and addressing rural-urban differences in the delivery of cancer control programs can enhance resource efficiency and promote health equity.

Artificial intelligence (AI) platforms have emerged as pivotal tools in genetics and molecular medicine, as in many other fields. The growth in patient data, identification of new diseases and phenotypes, discovery of new intracellular pathways, availability of greater sets of omics data, and the need to continuously analyse them have led to the development of new AI platforms. AI continues to weave its way into the fabric of genetics with the potential to unlock new discoveries and enhance patient care. This technology is setting the stage for breakthroughs across various domains, including dysmorphology, rare hereditary diseases, cancers, clinical microbiomics, the investigation of zoonotic diseases, omics studies in all medical disciplines. AI's role in facilitating a deeper understanding of these areas heralds a new era of personalised medicine, where treatments and diagnoses are tailored to the individual's molecular features, offering a more precise approach to combating genetic or acquired disorders. The significance of these AI platforms is growing as they assist healthcare professionals in the diagnostic and treatment processes, marking a pivotal shift towards more informed, efficient, and effective medical practice. In this review, we will explore the range of AI tools available and show how they have become vital in various sectors of genomic research supporting clinical decisions.

The acute toxicity (sometimes called "overdose" or "poisoning") crisis has affected Canadians across all stages of life, including youth, adults and older adults. Our biological risks and exposures to substances change as we age. Based on a national chart review study of coroner and medical examiner data on acute toxicity deaths in 2016 and 2017, this analysis compares the burden of deaths and circumstances of death, locations of acute toxicity event and death, health history and substances contributing to death of people, by sex and life stage.
This analysis reveals key differences in the characteristics of acute toxicity deaths by sex and life stage, and suggests potential intervention points for each group. Many people across demographics were alone while using substances before the acute toxicity event, and many were alone when they died. Youth, particularly female youth, more often died in circumstances where someone might have been available to help by calling 911 or administering first aid and naloxone. For the people who were in contact with health care prior to their death, about one-quarter (24%28%) of adults and older adults sought assistance for reasons related to pain. Youth more often sought assistance for a nonfatal acute toxicity event (13%14%) or for mental health (particularly female youth, 21%) than people in other life stages. Multiple substances contributed to most deaths, and both pharmaceutical and nonpharmaceutical substances were common causes of death for all life stages and sexes. There are demographic differences in the specific substances contributing to death.
Cette analyse présente les différences clés des caractéristiques des décès attribuables à une intoxication aiguë par sexe et stade de la vie, et propose des interventions possibles pour chaque groupe. Dans toutes les catégories démographiques, plusieurs personnes étaient seules au moment de consommer des substances avant l'intoxication aiguë, et plusieurs d'entre elles étaient seules au moment du décès. Les jeunes, et en particulier les jeunes femmes, sont décédées le plus souvent dans des circonstances où quelqu'un aurait pu être disponible pour aider en appelant le 911 ou en administrant les premiers soins et la naloxone. Parmi les personnes qui étaient en contact avec le système de santé avant leur décès, environ le quart (24 % à 28 %) des adultes et des aînés ont sollicité de l'aide pour des raisons liées à la douleur. Les jeunes ont plus souvent sollicité de l'aide pour une intoxication aiguë non mortelle (13 % à 14 %) ou pour des raisons liées à la santé mentale (en particulier les jeunes femmes, 21 %) que les personnes à d'autres stades de la vie. La polyconsommation de substances était en cause pour la plupart des décès, et les substances pharmaceutiques et non pharmaceutiques étaient toutes deux des causes courantes de décès pour tous les stades de la vie et les sexes. Il existe des différences démographiques en lien avec les substances spécifiques ayant contribué aux décès.

The incidence of breast cancer has been increasing significantly over the past decades, while the mortality rate has, actually, been decreasing. Behind this favorable trend in the decrease in mortality are not only high-quality screening programs, but also undoubtedly advances in therapy, especially new methods in surgical treatment. The importance of oncoplastic approach integrating resection and reconstruction procedures is obvious. Our efforts continue to maximize breast-conserving therapy, which is being improved in parallel with the development of new localization methods of non-palpable lesions. Breast-conserving therapy indication spectrum is also increasing with the use of oncoplastic approach allowing the resection of a significant part of the mammary gland while achieving an acceptable cosmetic result. We improve guidelines for skin-sparing procedures and also possibilities and availability of breast reconstruction. Most popular is breast reconstruction with free abdominal flap transfer. However, due to such demanding complex procedure with limited availability, there is also a significant development of silicone-implant-based reconstruction or methods of fat transfer. Constant attention is focused on axillary surgery, now especially in cases of initial nodal involvement that responds favorably to neoadjuvant systemic treatment. Current findings indicate tendency to modify and differentiate surgical indications according to the tumor phenotype. Complex lymphedema prevention surgery, such as lymphatic mapping or restoring lymphatic flow via microsurgical lymphaticovenous anastomosis, can provide effective and long-term improvement and is challenging. Recently in the Czech Republic, we reopened the discussion about the optimal concentration of medical care in a smaller number of specialized breast centers, which we think is one of a number of steps on the constant path to improve medical results.

Objective: To analyze the trend of dementia mortality rate among individuals aged 60 to 94 years in China from 1982 to 2021. Methods: Utilizing data from the Global Burden of Disease Study 2021, the Joinpoint regression model was employed to analyze the trend in the dementia mortality rate among Chinese older adults from 1982 to 2021. The age-period-cohort analysis method was used to decompose the age effect, period effect and cohort effect of dementia mortality data in Chinese elderly people. Results: From 1982 to 2021, the crude mortality rate of dementia in elderly women aged 60-94 in China (133.67/100 000-214.02/100 000) was higher than that in men (70.92/100 000-119.70/100 000), and the age-standardized mortality rate of dementia in women (230.74/100 000-246.87/100 000) was also higher than that in men (132.88/100 000-140.19/100 000). The age-standardized mortality rate of dementia in both genders showed an N-shaped fluctuation trend. The average annual percent change (AAPC) of dementia mortality rate in elderly males aged 60-94 was 0.07% (95%CI: 0.01%-0.13%), and the AAPC of dementia mortality rate in elderly females was -0.01% (95%CI:-0.08%-0.07%). Age effect analysis showed that from the age of 60, the risk of dementia death in males and females increased with age, especially among elderly people aged 75-94 who experienced a rapid increase in dementia mortality rate. The period effect analysis showed that the overall risk of dementia death in elderly men and women aged 60-94 was decreasing, but it had increased from 2017 to 2021. The cohort effect analysis showed that the risk of dementia death was lower in later birth cohorts. Conclusion: From 1982 to 2021, the dementia mortality rate among Chinese older adults aged 60 to 94 years exhibited fluctuations. Particularly, there has been a notable rebound in recent years. Special attention should be directed towards female seniors and those aged 75 to 94 years.
