Metabolic and behavioural risk factors for cardiovascular diseases in Southern Latin America: analysis of the Global Burden of Disease 1990-2019.

OBJECTIVES: Cardiovascular diseases (CVDs) are the leading causes of global mortality. Modifiable behavioural and metabolic risk factors significantly contribute to the burden of CVD. Given the vast socio-demographic and health outcome heterogeneity in Latin America, similar southern Latin American countries (Argentina, Chile, and Uruguay) were analysed as a distinct group to describe the CVD death rates related to metabolic and behavioural risk factors. STUDY DESIGN: An ecological study was performed using data from the Global Burden of Disease Study 2019. METHODS: Metabolic and behavioural risk factors-related CVD death were examined by analysing age-standardised rates per 100,000 individuals in the three countries between 1990 and 2019. RESULTS: While exposure to behavioural risk is decreasing, an upwards trend was observed in metabolic risks. Among the assessed risk factors, metabolic factors emerged as the primary contributors to deaths. High fasting plasma glucose exhibited a remarkable increase in relative importance across most studied contexts. Dietary risks stood out among behavioural factors due to their complexity and substantial changes observed. Although mortality rates have declined for overall CVD, peripheral artery disease mortality is rising. CONCLUSION: Modifiable behavioural and metabolic risk factors significantly influence CVD mortality in Southern Latin America. Despite the increasing exposure to metabolic risks, advancements in prevention and treatment are evidenced in the decline of mortality rates for most CVD. These findings emphasise the need for targeted interventions and comprehensive strategies to address their impact on cardiovascular health, advocating for healthy lifestyle behaviours to mitigate the progression and CVD development.

Prognostic factors affecting survival in metastatic soft tissue sarcoma: an analysis of 110 patients.

BACKGROUND: Data on treatment outcome and prognostic factors in patients with metastatic soft tissue sarcoma (STS) are limited in the literature. METHODS: A total of 119 patients with metastatic STS treated between June 2003 and December 2012 were analyzed for treatment outcome and prognostic factors. RESULTS: Median age was 37 years (range 2-72 years) with a male to female ratio of 1.5:1. Most common histologic subtypes were synovial sarcoma (36 %) and leiomyosarcoma (16 %). Median tumor size was 12 cm (range 1.6-30 cm). Twenty-four (20 %) patients were treated with multimodality therapy and 80 % patients received systemic chemotherapy alone. At a median follow-up of 10 months (range 1-66 months), the 2-year EFS and OS were 10 and 19 %, respectively, with a median EFS and OS of 6 and 10 months, respectively. Univariate analysis identified albumin ≤4 g/dl (p = 0.001), histologic subtypes other than synovial sarcoma (p = 0.02), non-extremity tumors (p = 0.03) and single modality treatment (p = 0.03) as factors predicting poor EFS; however, for OS, hemoglobin ≤10 g/dl (p = 0.02), tumor size >10 cm (p = 0.01) and single modality treatment (p = 0.04) were identified as poor prognostic factors. Multivariate analysis identified only serum albumin ≤4 g/dl (p = 0.002, HR 0.47, 95 % CI 0.29-0.75) associated with poor EFS; however, for OS, hemoglobin ≤10 g/dl (p = 0.009, HR 0.49, 95 % CI 0.29-0.83), tumor size >10 cm (p = 0.003, HR 2.11, 95 % CI 1.28-3.47) and single modality treatment (p = 0.01, HR 0.47, 95 % CI 0.25-0.86) emerged as poor prognostic factors. CONCLUSIONS: Serum albumin, tumor size, hemoglobin and treatment modality affect survival in metastatic STS.
