Aim: To study nutritional status in chronic obstructive pulmonary disease (COPD) in relation to the serum content of adipose tissue hormones.
Subjects And Methods: Ninety-four patients with Stages II and III COPD and 20 gender- and age-matched healthy non-smoking volunteers were examined. Interviews, analysis of laboratory data, enzyme immunoassay, and somatometry were made.
Results: The patients with COPD are characterized by the development of malnutrition, even in the absence of body weight loss and in the presence of normal body mass index (BMI) with predominant lean body mass (LBM) loss, normal serum concentrations of adipose tissue hormones. With more advanced COPD and a worse nutritional status, the level of leptin decreases and that of adiponectin increases. The content of adiponectins is closely related to the indicators of nutritional status, mainly to the value of body weight loss, BMI, LBM, absolute blood lymphocyte count, and degree of malnutrition. The COPD patients with emphysema show the most pronounced changes in nutritional status and higher adiponectin levels.
Conclusion: An integrated assessment of the degree of protein-energy malnutrition and measurement of the level of adipose tissue hormones should be made when nutritional status is studied in patients with COPD.

Purpose: The demographic transition toward aging heralds an increase in the number of geriatric patients with cancer in India. Comprehensive geriatric assessment (CGA) is a sine qua non for treatment planning and shared decision making in these patients. We aimed to study the prevalence of malnutrition and the associated risk factors in geriatric patients with solid organ cancer.

Background: Predicting mortality and morbidity poses a significant challenge to physicians, leading to the development of various scoring systems. Among these, the hemoglobin, albumin, lymphocyte and platelet (HALP) score evaluates a patient's nutritional and immune status. The primary aim of this study was to determine the predictive effect of the HALP score on 30-day and 1-year mortality in elderly patients with proximal femoral fractures (PFFs).

Colorectal cancer (CRC) is commonly treated with intestinal resections that lead to colostomy, which can influence changes in eating habits. This study aimed to analyze energy and nutrient intake, diet quality, and food consumption based on the processing level in CRC patients after colostomy. A prospective study was carried out at three time points (T0-recent colostomy, T1-3 months after colostomy, and T2-6 months after colostomy).

Background: Due to declining birthrate and increasing longevity, the number of older people living alone with cognitive impairment is rapidly increasing in Japan. They have a lot of challenges in terms of health, housing, finance, daily life and protection of rights, all of which should be clarified to create inclusive, equitable, and sustainable super-aged societies.
Methods: A series of factual investigation was conducted using existing statical materials, community-based epidemiological studies, clinic-based case studies, and literature reviews.
