AI Article Synopsis
- The study examined how anemia and dynapenia (muscle weakness) affect mortality risk in older adults, particularly focusing on their combined impact and any gender differences.
- Over a 10-year follow-up of 5,310 participants, it was found that those with both conditions had a significantly higher mortality risk compared to those without.
- The results indicated that the combination of anemia and dynapenia raised the mortality risk more in women than men, emphasizing the importance of early diagnosis and treatment for these health issues.
Article Abstract
Background/objective: Anemia and dynapenia can occur simultaneously. Separately, both conditions increase the mortality risk with advancing age. However, there is no epidemiological evidence on the combined effect of these conditions on mortality in older adults. We investigated whether combined anemia and dynapenia increase the mortality risk, and whether there are gender differences.
Methods: A 10-year follow-up study was conducted involving 5,310 older adults from the English Longitudinal Study of Ageing (ELSA). According to the diagnosis of anemia (hemoglobin concentration < 13.0 g/dL in men and < 12.0 g/dL in women) and dynapenia (grip strength < 26 kg for men and < 16 kg for women), individuals at baseline were categorized as "non-anemic/non-dynapenic", "dynapenic", "anemic" and "anemic/dynapenic". The outcome was all-cause mortality during the follow-up period.
Results: A total of 984 deaths were computed during the follow-up (63.7% in non-anemic/non-dynapenic, 22.8% in dynapenic, 7.5% in anemic and 6.0% in anemic/dynapenic). Adjusted Cox proportional hazard models stratified by sex showed that anemia and dynapenia combined was associated with an increased mortality risk in men (HR: 1.64; 95% IC 1.08 - 2.50) and women (HR: 2.17; 95% CI 1.44 - 3.26). Anemia in men (HR: 1.68; 95% CI 1.22 - 2.32) and dynapenia in women (HR: 1.37; 95% CI 1.09 - 1.72) were also risk factors for mortality.
Conclusions: The coexistence of anemia and dynapenia increases the mortality risk, highlighting the need for early identification, prevention, and treatment of these conditions to reduce their complications and the mortality risk.

Body composition abnormalities are prognostic markers in several types of cancer, including colorectal cancer (CRC). Using our data distribution on body composition assessments and classifications could improve clinical evaluations and support population-specific opportune interventions. This study aimed to evaluate the distribution of body composition from computed tomography and assess the associations with overall survival among patients with CRC.

This study presents a web application for predicting cardiovascular disease (CVD) and hypertension (HTN) among mine workers using machine learning (ML) techniques. The dataset, collected from 699 participants at the Gol-Gohar mine in Iran between 2016 and 2020, includes demographic, occupational, lifestyle, and medical information. After preprocessing and feature engineering, the Random Forest algorithm was identified as the best-performing model, achieving 99% accuracy for HTN prediction and 97% for CVD, outperforming other algorithms such as Logistic Regression and Support Vector Machines.
