AI Article Synopsis
- - The study looked at how older adults' feelings about a behavior change intervention, specifically related to physical activity, connect to its effectiveness, especially in terms of weight loss.
- - Sentiment was analyzed from exit interviews using a "bag of words" method, focusing on the emotional tone of older adults with obesity, and findings showed notable results among participants (average age 73).
- - Results indicated a strong link between positive feelings about the intervention and actual weight loss, as well as improvements in perceived health, suggesting that participants' perceptions can significantly influence clinical outcomes.
Article Abstract
Background: Older adults frequently participate in behavior change studies, yet it is not clear how to quantify a potential relationship between their perception of the intervention and its efficacy.
Research Aim: We assessed the relationship between participant sentiment toward the intervention from follow-up interviews with physical activity and questionnaires for the perception of health.
Methods: Sentiment was calculated using the transcripts of exit interviews through a bag of words approach defined as the sum of positive and negative words in 28 older adults with obesity (body mass index ≥30kg/m).
Results: Mean age was 73 years (82% female), and 54% lost ≥5% weight loss. Through linear regression we describe a significant association between positive sentiment about the intervention and weight loss; positive sentiment on technology and change in PROMIS-10 physical health and reduced physical activity time, while controlling for sex and age.
Conclusions: This analysis demonstrates that sentiment analysis and natural language processing in program review identified an association between perception and topics with clinical outcomes.

Quantification of racial and ethnic disparities in alcohol-related problems in light of different methodological approaches.

Alcohol Research Group, Public Health Institute, Emeryville, CA, USA.
Aim: We applied the Institute of Medicine (IOM) definition of racial and ethnic disparities in healthcare to estimate disparities in alcohol-related problems. This estimation involved adjusting for drinking patterns, gender and age, with observed disparities further explained by socioeconomic status (SES). We compared results of five statistical approaches which use different methods for adjusting covariates.

Aim: Total proctocolectomy (TPC) is the standard of care for patients with ulcerative colitis (UC) and dysplasia not amenable to endoscopic management. However, the risks of an extensive resection may outweigh the benefits in high-risk surgical patients. Therefore, we performed a systematic review and meta-analysis to assess postoperative outcomes between segmental colectomy (SEG) versus TPC in patients with UC.

Background And Purpose: We investigated the relationship between serotonergic and dopaminergic specific binding transporter ratios (SBRs) over 4 years in Parkinson's disease (PD) patients. We assessed serotonergic innervation's potential compensatory role for dopaminergic denervation, association with PD symptoms, and involvement in the development of levodopa-induced dyskinesia (LID).
Methods: SBRs of the midbrain and striatum were evaluated from [I-123] N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane SPECT images at baseline and after 4 years.
Molecular Identification and Antifungal Susceptibility of Fusarium spp. Clinical Isolates.

Clinical Microbiology Laboratory, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico.
Background: Accurate identification of Fusarium species requires molecular identification. Treating fusariosis is challenging due to widespread antifungal resistance, high rates of treatment failure, and insufficient information relating antifungal susceptibility to the clinical outcome. Despite recent outbreaks in Mexico, there is limited information on epidemiology and antifungal susceptibility testing (AST).
