[Prevalence, knowledge and control of arterial hypertension in vulnerable neighborhoods of Argentina: A Cross-sectional Study]. / Estudio de prevalencia, conocimiento y control de la hipertensión arterial en barrios vulnerables de Argentina.

INTRODUCTION: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. METHODS: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. RESULTS: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence. Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. CONCLUSION: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations. Inadequate use of combination therapy was observed. This study underscores the urgent need for targeted interventions addressing cardiovascular risk factors in poor areas to mitigate the burden of CVD.

Efficacy and toxicity of 5-fluorouracil and folates in advanced colon cancer.

From February 1987 to December 1988, 34 patients with histologically confirmed advanced colorectal carcinoma were entered in a phase II trial with 5-fluorouracil (5-FU) and folinic acid, for evaluation of treatment effectiveness and toxicity. Our data confirmed that the association 5-FU and folates represents an effective and moderately tolerated palliative treatment, with diarrhea being the only dose-limiting toxicity.

The acute metabolic abnormalities associated with cancer may cause symptoms that require urgent medical treatment and may constitute a more dangerous threat to life than the cancer itself. Hypercalcaemia is probably the most common metabolic complication of neoplastic disease (occurring in up to 30% of cancer patients) and its timely treatment may often save the patient and may permit subsequent chemotherapy. In this communication we focused our attention on the pathogenetic mechanism (part 1), diagnosis and subsequent treatment of this metabolic disorder (part 2).
