Demographic and biological factors in interrelationships between physical, cognitive, psychological, and social frailty in community-dwelling older adults: Data from the Birjand Longitudinal Aging Study (BLAS).

Complex interrelationships may exist among different types of frailty. This study aimed to evaluate the demographic and biological factors that influence the different types of frailty in community-dwelling older adults in Iran through a cross-sectional analysis of data obtained from the Birjand Longitudinal Aging Study. This study is an ongoing cohort study of people aged 60 years and over and employed a multistage stratified cluster random sampling.

Effects of hospital-to-home transitional care on health outcomes of elderly patients in Islamic Republic of Iran.

Background: Hospitalization has a negative effect on the functional and clinical outcomes of elderly patients.

Aims: To evaluate the effect of a care transition intervention on functional and clinical outcomes and quality-of-life of elderly patients in the Islamic Republic of Iran after hospital discharge during a 3-month follow-up.

Methods: We conducted a randomized controlled trial of 304 elderly hospitalized patients in Tehran from December 2018 to January 2020.

A systematic study of nano-based fibrous systems: Diagnostic and therapeutic approaches for dementia control.

Nano-based systems provide many advantages, including eluding gastrointestinal and first-pass metabolism of the drug and improving the potential advantage of reduced doses of drugs for an equal or better therapeutic effect compared to other parts of oral administration. Over the last few years, protein-based nanofibrous biomaterials have been used for better controlling dementia. PubMed, Scopus, and ISI Web of Science were consulted for available articles on nano-based fibrous systems for the treatment and diagnosis of dementia (up to October 2022).

Tryptophan and serotonin levels as potent biomarkers in diabetes mellitus complications: a new approach of diagnostic role.

Objective: Alterations in the serotonergic system were verified to act a role in the pathogenesis of altered neurological and psychiatric diseases. In recent years, Tryptophan (Trp) and serotonin (5-HT) levels have been considered potent biomarkers of diabetes mellitus (DM).

Method: The different Trp metabolism may also play roles in the pathogenesis of DM and mounting risk of complications.

Interactive relationship between Trp metabolites and gut microbiota: The impact on human pathology of disease.

Tryptophan (Trp), an α-amino acid, is the precursor of serotonin (5-hydroxytryptamine, 5-HT), which is involved in a variety of features of metabolic function and human nutrition. Evidence highlights the role of Trp metabolites (exclusively 5-HT) in the gastrointestinal (GI) tract; however, the mechanisms of action involved in the release of 5-HT in the GI tract are still unknown. Considering the fact that variations of 5-HT may facilitate the growth of certain GI disorders, gaining a better understanding of the function and release of 5-HT in the GI tract would be beneficial.

Diagnosis of frailty in geriatric patients: Is the pictorial fit frail scale an appropriate screening tool in hospital settings?

Background: Frailty is accompanied by serious health complications in the elderly, especially during hospitalization. Visual scales have been designed for quick and easy evaluation of frailty in different cultures and settings. Therefore, this study aimed to define the accuracy of the Pictorial Fit Frail Scale (PFFS) for frailty screening in the hospitalized elderly in Iran.

Role of frailty in prediction of hospitalized older adult patient’s outcomes: a prospective study.

Background/aim: Frailty is associated with an increased risk of negative short-term and long-term hospital outcomes. This study aimed to evaluate the role of frailty in predicting readmission, length of stay, and quality of life in the hospitalized older adults.

Materials And Methods: This observational study was conducted at Ziaiyan Hospital, Tehran, Iran.
