RESUMEN
BACKGROUND: The aim of this study was to investigate the relationship between DII and sarcopenia in individuals with ischemic heart disease (IHD). METHODS: This was a retrospective study utilizing data of the National Health and Nutrition Examination Survey (NHANES) from 1999-2004. Adults aged ≥50 years diagnosed with IHD, having complete 24-hour dietary recall data, and dual energy X-ray absorptiometry (DEXA)-measured muscle mass were eligible for inclusion. Association between DII and sarcopenia, defined by reduced appendicular skeletal muscle mass, was determined by the logistic regression analyses. RESULTS: Data of 1088 individuals were analyzed, with the mean age of 68.1±0.5 years. Significantly higher DII was observed in the sarcopenic group compared to the non-sarcopenic group (0.24 vs. -0.17, P=0.020). After adjusting for relevant confounders in the multivariable analysis, each unit increase in DII was significantly associated with higher odds of sarcopenia (adjusted odd ratio [aOR]=1.07, 95% confidence interval: 1.00-1.14, P value = 0.040). In stratified analyses, among patients with a Body Mass Index (BMI) ≥30 kg/m2, both DII tertile 2 and tertile 3 were significantly associated with greater odds of sarcopenia (tertile 2 vs. tertile 1: aOR=2.85, 95% CI: 1.56-5.23, P=0.001; tertile 3 vs. tertile 1: aOR=3.11, 95% CI: 1.53-6.31, P=0.002), whereas no significant associations was observed among patients with a BMI<30 kg/m2. CONCLUSIONS: This study has established a significant independent association between a higher DII and an increased risk of sarcopenia in US adults with IHD regardless of type of IHD. BMI appears as a moderating factor in this association.
RESUMEN
CASE PRESENTATION: A 56-year-old Chinese man, who did not smoke, presented with a 2-month history of cough and bloody sputum. He also complained of fatigue, night sweats, chest pain, and shortness of breath, with no chills or loss of weight. He previously worked as a veterinarian and had been infected with Brucella 30 years ago. Additionally, he had been diagnosed with tuberculous pleurisy and completed a 1-year anti-TB treatment. Subsequently, he had been well until 2 months before the current admission. A chest CT scan showed a cruciform calcification in the mediastinum and some tree-in-bud changes. The results of the purified protein derivative skin test and interferon-gamma release assay for TB were negative. Brucella agglutination test was also negative. On the night of admission, the patient coughed up two silver-white-colored shiny stones and had a fever of up to 38.5 °C on the following days.

BACKGROUND: Despite the growing epidemic of heart failure (HF), there is limited data available to systematically compare non-cardiac comorbidities in the young-old, old-old, and oldest-old patients hospitalized for HF. The precise differences will add valuable information for better management of HF in elderly patients. METHODS: A total of 1053 patients aged 65 years or older hospitalized with HF were included in this study. Patients were compared among three age groups: (1) young-old: 65 to 74 years, (2) old-old: 75 to 84 years, and (3) oldest-old: ≥85 years. Clinical details of presentation, comorbidities, and prescribed medications were recorded. RESULTS: The mean age was 76.7 years and 12.7% were 85 years or older. Most elderly patients with HF (97.5%) had at least one of the non-cardiac comorbidities. The patterns of common non-cardiac comorbidities were different between the young-old and oldest-old group. The three most common non-cardiac comorbidities were anemia (53.6%), hyperlipidemia (45.9%), and diabetes (42.4%) in the young-old group, while anemia (73.1%), infection (58.2%), and chronic kidney disease (44.0%) in the oldest-old group. Polypharmacy was observed in 93.0% elderly patients with HF. Additionally, 29.2% patients were diagnosed with infection, and 67.0% patients were prescribed antibiotics. However, 60.4% patients were diagnosed with anemia with only 8.9% of them receiving iron repletion. CONCLUSIONS: Non-cardiac comorbidities are nearly universal in three groups but obviously differ by age, and inappropriate medications are very common in elderly patients with HF. Further treatment strategies should be focused on providing optimal medications for age-specific non-cardiac conditions.
