The interface between ageing and health in man

Morbidity Profile and Healthcare Service Utilization Pattern Among Geriatric Population in the Rural Himalayan Region of Uttarakhand, India: A Cross-Sectional Study

OBJECTIVES

The increasing elderly population, along with their health problems, is a matter of concern, especially in the difficult terrains of the hilly Himalayan region of northern India. Hence, the present study was conducted to assess the healthcare-seeking behavior of the elderly and adherence to medication.

METHODS

The present community-based cross-sectional study was conducted on 250 elderly participants by a consecutive sampling method. Data were collected during the months of July 2021 to October 2021 after obtaining institutional ethical clearance. Bivariate logistic regression was done to assess factors associated with healthcare services utilization patterns and adherence to medications in chronic diseases. Significant factors were then analyzed with a multivariate logistic regression model. Variables with p-value <0.05 on multivariate analysis were considered statistically significant.

RESULTS

The mean age of the study participants was 67.2 (±8.09) years, and 52% were males. Chronic illness was diagnosed in 45.6% participants. Only 121 (48.4%) participants were aware of health insurance schemes among whom 95 (38%) were registered. Appropriate healthcare-seeking behavior for acute illness episodes was seen in 68.9% of participants. A government healthcare facility was the most preferred facility. Low adherence to chronic disease medication was seen in 41.2%. Participants registered under any health insurance scheme had higher adherence to medications (OR=0.36; 95% CI, 0.15-0.86; p-value=0.02).

CONCLUSIONS

The majority of the participants preferred government healthcare facilities. Registration under any health insurance scheme was found to significantly influence adherence to medications. Further qualitative studies can be of paramount importance in understanding the perspectives of the geriatric population in the study area.

Emerging molecular mediators and targets for age-related skeletal muscle atrophy

The age-associated decline in muscle mass has become synonymous with physical frailty among the elderly due to its major contribution in reduced muscle function. Alterations in protein and redox homeostasis along with chronic inflammation, denervation, and hormonal dysregulation are all hallmarks of muscle wasting and lead to clinical sarcopenia in older adults. Reduction in skeletal muscle mass has been observed and reported in the scientific literature for nearly 2 centuries; however, identification and careful examination of molecular mediators of age-related muscle atrophy have only been possible for roughly 3 decades. Here we review molecular targets of recent interest in age-related muscle atrophy and briefly discuss emerging small molecule therapeutic treatments for muscle wasting in sarcopenic susceptible populations.

Neuroendocrine regulation of inflammation

The interaction between the sympathetic nervous system and the immune system has been documented over the last several decades. In this review, the neuroanatomical, cellular, and molecular evidence for neuroimmune regulation in the maintenance of immune homeostasis will be discussed, as well as the potential impact of neuroimmune dysregulation in health and disease.

Morbidity Pattern and Health-seeking Behavior of Aged Population residing in Shimla Hills of North India: A Cross-Sectional Study

BACKGROUND

Population aging is a global phenomenon. In India, the size of the elderly population is growing fast. Many older adults have multiple medical conditions. Understanding elderly health problems and health-seeking behavior is prerequisite for proving comprehensive geriatric care to them.

OBJECTIVES

To assess the morbidity pattern and study the health-seeking behavior of the elderly people of Shimla district in Himachal Pradesh.

MATERIALS AND METHODS

A total of 400 elderly people aged 60 years and above were selected from urban and rural areas of Shimla hills in North India by simple random sampling. Statistical software Epi info software version 3.2 was used for analyzing data. Descriptive statistics were used to describe sociodemographic and morbidity variables.

RESULTS

The most common morbidity identified among them were musculoskeletal problems (55.0%) followed by hypertension (40.5%). Two third were seeking treatment for their health problems. Among older persons not seeking treatment for their medical condition, most considered these morbidities as an age-related phenomenon. Many perceived that the health services were too far.

CONCLUSION

The high morbidity load among elderly in the present study stresses for efforts to provide better health care to them and thus ensure that they remain active members of our society. Residence emerged out to be most significant determinant of healthcare-seeking behavior. Policy makers must focus on rural elderly and their beliefs which prevent them from seeking healthcare.

One for all and all for one: thymic epithelial stem cells and regeneration

It has long been believed that the thymic epithelial microenvironment originates from both the endodermal and ectodermal germ cell layers. However, a growing body of evidence indicates that such a dual origin is not the case, and that the diverse thymic epithelial populations all develop from a common epithelial stem cell. This article explores these data, investigates the identity of such cells and the signals that might control their expansion and differentiation, and considers the possibility of stem cell transplantation for thymic regeneration.

The role of immunity in susceptibility to respiratory infection in the aging lung

Respiratory tract infections, particularly pneumonia, are a leading cause of death in persons 65 years or older in both developed and developing countries. Because many attributes of immunity wane with advancing age, the elderly may be more susceptible to respiratory infections, even if they appear to be in good health. A decline in the ability of lymphoid tissues to mount an antigen-specific response (adaptive immunity) to specific microorganisms such as influenza virus or Streptococcus pneumoniae is thought to be an important factor in increasing susceptibility to respiratory tract infection with advancing age. However, abnormalities in innate immunity may also contribute to increased susceptibility to respiratory infections and have been poorly characterized in the elderly. Although changes in immune parameters such as T cell subsets and immunoglobulin concentrations have been observed in respiratory secretions from older healthy individuals compared to younger subjects, the significance of these changes for protective immunity in the lung is unknown. The incidence of pneumonia may be lessened by measures such as optimizing treatment of comorbid conditions, optimizing nutrition, and addressing swallowing disorders. The use of vaccines directed against the influenza virus and S. pneumoniae appears to have made an impact on the degree of morbidity and mortality, and perhaps, the incidence, of community-acquired pneumonia. However, better stimulation of specific immune responses with improved vaccines and more widespread use of these vaccines for protection of elderly individuals are needed.
