A Conceptual Model to Improve Care for Individuals with Alzheimer's Disease and Related Dementias and Their Caregivers: Qualitative Findings in an Online Caregiver Forum.

BACKGROUND: As the population rapidly ages, a growing number of families are engaging in care for individuals living with Alzheimer's disease and related dementias (ADRD). The perceived challenges and burdens that face informal caregivers are enormous. OBJECTIVE: The objective of this study was to 1) explore from the family caregivers' perspective, the daily lives of individuals living with ADRD, and the challenges family caregivers encounter when caring for a family member with ADRD; and 2) to develop a comprehensive model with the endeavor to improve care for individuals with ADRD and their family caregivers. METHODS: Posts were extracted from the ALZConnected online caregiving forum in May 2019. Guided by a triangular model focused on Caregiver, Individual with ADRD, and Context of Care, two researchers independently analyzed 654 posts with a combination of deductive and inductive thematic analysis approach. Researchers all agreed on finalized codes and themes. RESULTS: Thematic analysis resulted in four themes: Individual with ADRD, Caregiver, Dynamic between Caregiver and Individual with ADRD, and Context of Care. The most frequently discussed topics among caregivers were informational and emotional support for caregivers, and the capabilities and functioning of individuals with ADRD. CONCLUSION: Online forums provide a valuable platform for caregivers to support each other informationally and emotionally, share care strategies, and navigate caregiving burdens. An expanded model was derived to support a comprehensive and dynamic approach to improve care for both caregivers and individuals with ADRD. The unique nature of the caregiver forum data is worthy of further data mining using a novel analysis approach.

Spectrophotometric determination of the total phenolic content, spectral and fluorescence study of the herbal Unani drug Gul-e-Zoofa (Nepeta bracteata Benth).

OBJECTIVES: This study quantitatively determined the total phenolic contents in ethanolic and aqueous extracts of Gul-e-Zoofa (flowers of Nepeta bracteata Benth) using a spectrophotometric method. We also performed a spectral study (UV and IR) of the ethanolic extract and a fluorescence study of the powdered drug and successive extracts to identify and characterize the genuine herbal drug, which has not been previously performed. METHODS: The total phenolic content was determined quantitatively using the Folin Ciocalteu reagent, with Gallic acid as the standard. The fluorescence characteristics of the powdered drug and successive extracts with and without chemical treatment during the day and under a UV light were recorded. The UV and IR spectra of the alcoholic extract of Gul-e-Zoofa were recorded using a spectrometer. RESULTS: The total phenolic contents of the alcoholic and aqueous extracts were found to be 326.28 and 319.14 mg/g of the Gallic acid equivalent (GAE), respectively. The wavelength of the maximum absorption in the UV spectrum was 320 nm, and the characteristic frequencies in the IR spectrum were 3465.31, 3220.07, 2927.3, 2856.1, 1709.07, 1610.19, 1404.5, 1250.2, 1056.42, 823.04, 775.58, 577.81, and 463.10 cm-1. The fluorescence characteristics of the powdered drug were also observed. CONCLUSION: This spectral and fluorescence study of the drug will be helpful for confirming the identity and purity of the genuine drug. The total phenolic content will be helpful for developing new drugs and standardizing the drug. The presence of a high total phenolic content shows that the flowers of N. bracteata Benth may possess antioxidant properties, which could lead to a new field of research in the future.

Synthesis and anti-tumor evaluation of B-ring substituted steroidal pyrazoline derivatives.

The synthesis and anti-tumor activity screening of new steroidal derivatives (4-18) containing pharmacologically attractive pyrazoline moieties are performed. During in vitro anticancer evaluation, the newly synthesized compounds displayed moderate to good cytotoxicity on cervical and leukemia cancer cell lines. In addition these compounds were found to be nontoxic to normal cell (PBMCs) (IC50>50 µM). The structure-activity relationship is also discussed. The most effective anticancer compound 9 was found to be active with IC50 value of 10.6 µM. It demonstrated significant antiproliferative influence on Jurkat cell lines. The morphological changes and growth characteristics of HeLa cells treated with compound 4 were analyzed by means of SEM.
