RESUMO

OBJECTIVES: Excess adiposity is associated with several factors involved in carcinogenesis and breast cancer progression. Evidence supporting the role of body composition in breast cancer treatment is promising, but still scanty and mainly focused on adjuvant treatment. The aim of this study was to evaluate the changes in body composition during neoadjuvant chemotherapy and its association with pathologic complete response and survival outcome in patients treated for operable/locally advanced breast cancer. METHODS: A retrospective review of patients with breast cancer treated with neoadjuvant chemotherapy was performed in the Oncology Section of the Department of Medicine, University of Verona between 2014 and 2019. Body composition was evaluated from clinically acquired computed tomography scans at diagnosis and after neoadjuvant chemotherapy. Descriptive statistic was adopted. The associations of body composition measures with pathologic complete response and disease-free survival were analyzed. Kaplan-Meier curves were compared with log-rank analysis. RESULTS: Data from 93 patients were collected. After neoadjuvant chemotherapy, the adipose compound changed significantly across all body mass index categories. Body composition parameters had no significant effect on pathologic complete response. Survival analysis showed that a high gain of visceral adipose tissue during neoadjuvant chemotherapy was associated with shorter disease-free survival (hazard ratio, 10.2; P = 0.026). In particular, disease-free survival was significantly worse in patients who gained ≥10% of visceral adipose tissue compared with patients who gained <10% of visceral adipose tissue (5-y disease-free survival 71.4 versus 96.3, P = 0.009, respectively). CONCLUSIONS: Our results indicated that neoadjuvant chemotherapy significantly affects body composition, which seems to have an effect on survival outcome of breast cancer, highlighting the relevance of the body composition assessment when estimating treatment outcomes.

RESUMO

Carbon monoxide acute intoxication is a common cause of accidental poisoning in industrialized countries and sometimes it produces a real mass casualty incident. The incident described here occurred in a church in the province of Verona, when a group of people was exposed to carbon monoxide due to a heating system malfunction. Fifty-seven people went to the Emergency Department. The mean carboxyhemoglobin (COHb) level was 10.1±5.7% (range: 3-25%). The clinicians, after medical examination, decided to move 37 patients to hyperbaric chambers for hyperbaric oxygen (HBO) therapy. This is the first case report that highlights and analyses the logistic difficulties of managing a mass carbon monoxide poisoning in different health care settings, with a high influx of patients in an Emergency Department and a complex liaison between emergency services. This article shows how it is possible to manage a complex situation with good outcome. (Disaster Med Public Health Preparedness. 2017;11:251-255).

RESUMO

Primary aldosteronism (PA) is the most frequent form of secondary hypertension, but diagnostic tools for this disease still lack optimal accuracy. The heart is one important target tissue for damage due to excess aldosterone, and the role of natriuretic peptides is well recognized in diagnosing heart failure. We hypothesized that measuring the NT-proBNP could improve the diagnostic evaluation of PA. We enrolled 132 hypertensive patients, who underwent aldosterone to renin ratio (ARR) screening, and 81 underwent an intravenous saline loading test (ivSLT) because of a high ARR. The NT-proBNP level positively correlated with the ARR and inversely correlated with the renin level. The NT-proBNP level was higher in patients with a high ARR than in those with a low ARR and higher in patients with a positive ivSLT than in those with a negative ivSLT. After logistic regression analysis, an NT-proBNP value above the median and male gender were predictors of a positive ivSLT. The proportion of patients with a positive ivSLT ranged from only 23 % in females with a low NT-proBNP to 93 % in males with a high NT-proBNP. NT-proBNP and gender are predictors of a positive PA confirmatory test. These findings highlight the possibility of using NT-proBNP to identify which patients with a high ARR should receive a complete PA diagnostic evaluation.
