Glutathione sodium salt as a novel adjunctive treatment for acute myocardial infarction.

Timely recanalization of infarct related artery along with effective myocardial cell reperfusion represents a major challenge in the management of STEMI. The reperfusion of coronary arteries can induce further cardiomyocyte death by generating oxidative stress, which itself can mediate myocardial damage through a number of different mechanisms. Based on experimental and clinical studies, interventions to treat reperfusion injury by antioxidants were considered to be an appropriate therapeutic option. We emphasize the hypothesis that glutathione sodium salt, a physiologic antioxidant, may be of value when administered to STEMI patients both at an early stage of myocardial reperfusion by primary angioplasty and for up to three days after the procedure, in addition to standard treatment.

Randomised, double-blind, placebo-controlled, assessment of the efficacy and safety of dietary supplements in prehypertension.

We aimed to evaluate efficacy and tolerability of a protocol including lifestyle modifications and a novel combination of dietary supplements in prehypertension. A prospective, double-blind, randomised, placebo-controlled trial was conducted in 176 subjects (103 men, aged 52±10 years), with blood pressure (BP) of 130-139 mm Hg systolic and/or 85-89 mm Hg diastolic entered. After a single-blind run-in period, participants were randomised to twice daily placebo (n=88) or a commercially available combination pill (n=88). Primary endpoints were the differences in clinic BP between the two groups at the end of the trial. Secondary endpoints included intragroup differences in clinic BP during the study period and response rates (that is, BP <130/85 mm Hg or a BP reduction >5 mm Hg on week 12). Baseline characteristics were similar among the treatment groups. At 12 weeks, the supplement group had lower systolic BP (124±9 versus 132±7 mm Hg, P<0.0001) and similar diastolic BP (81±8 versus 82±7 mm Hg, P=0.382) compared to the placebo group. With respect to baseline measures, changes in BP with supplements were statistically significant for systolic (-9.3±4.2 mm Hg, P<0.0001) and diastolic values (-4.2±3.6 mm Hg, P<0.0001). Changes versus baseline in systolic and diastolic BP, conversely, were not different on placebo. The overall response rate at week 12 was significantly greater with supplements than placebo (58% (51 of 88) and 25% (22 of 88), respectively, P<0.0001). This randomised trial shows that combination of supplements with BP-lowering effect is an effective additional treatment to conventional lifestyle modifications for a better control of systolic BP in prehypertension.

Role of circulating tumor cells as prognostic marker in resected stage III colorectal cancer.

BACKGROUND: The prognostic role of circulating tumor cells (CTC) in early colorectal cancer (CRC) has not been determined yet. We evaluated the potential prognostic value of CTC in stage III CRC patients. PATIENTS AND METHODS: Prospective multicenter study of 519 patients with stage III CRC recruited between January 2009 and June 2010. CTC were enumerated with the CellSearch System after primary tumor resection and before the start of adjuvant therapy. A total of 472 patients were included in the analysis. RESULTS: CTC ≥1, ≥2, ≥3 and ≥5 were detected in 166 (35%), 93 (20%), 57 (12%) and 34 (7%) patients, respectively. Median follow-up was 40 months. In the overall population, CTC ≥1 (disease-free survival (DFS): HR 0.97, P = 0.85; overall survival (OS): HR 1.03, P = 0.89), ≥2 (DFS: HR 1.07, P = 0.76; OS: HR 1.02, P = 0.95), ≥3 (DFS: HR 0.96, P = 0.87; OS: HR 0.74, P = 0.41) and ≥5 (DFS: HR 0.72, P = 0.39; OS: HR 0.48, P = 0.21) were not associated with worse DFS and OS. No clinicopathological characteristics were significantly associated with the presence of CTC. In patients with disease relapse, the proportion with CTC ≥1 was not significantly different between those with single versus multiple metastatic locations (37.9% versus 31.4%, P = 0.761). In the multivariate analysis, CTC ≥1 was not an independent prognostic factor for DFS (HR 0.97, P = 0.87) and OS (HR 0.96, P = 0.89). CONCLUSION: CTC detection was not associated with worse DFS and OS in patients with stage III CRC. Given the scarcity of CTC in these patients, it is likely that CTC determined by CellSearch system does not have a prognostic role in this setting. However, a longer follow-up is needed.

Spontaneous-idiopathic left anterior descending artery dissection: is watchful waiting better than immediate stenting?

Spontaneous coronary artery dissection (SCAD) is a rare, complex disease, nowadays poorly understood yet. The lack of firm recommendations about this issue is a great limitation which makes any therapeutic decision controversial. The case described is that of a young, otherwise healthy woman, who presented with an ostial dissection of the left anterior descending (LAD) artery. Due to patient's stable clinical and hemodynamic parameters, we used a cautious approach based on watchful waiting and medical therapy, postponing stenting in order to achieve a partial vessel reopening with a more comfortable access to PCI.

Phase II open-label study of erlotinib in combination with gemcitabine in unresectable and/or metastatic adenocarcinoma of the pancreas: relationship between skin rash and survival (Pantar study).

BACKGROUND: Skin rash is an adverse event which might be associated with longer survival in patients treated with epidermal growth factor receptor tyrosine kinase inhibitors. The aim of this nonrandomised phase II clinical trial is to prospectively evaluate the relationship between skin rash and overall survival (OS) in advanced/metastatic pancreatic cancer treated with erlotinib plus gemcitabine. PATIENTS AND METHODS: Patients were given gemcitabine (1000 mg/m2/week, 3 weeks every 4 weeks) plus erlotinib (100 mg/day orally continuously) until disease progression/unacceptable toxicity. The primary end point was OS. RESULTS: A total of 153 eligible patients were enrolled (grade≥2 rash, 25%; grade<2 rash, 75%). OS was longer in patients with grade≥2 rash versus grade<2 (11 versus 5 months; P<0.001). Progression-free survival was longer in patients with grade≥2 rash versus grade<2 (6 versus 3 months; P<0.001) and shorter in those without rash versus grade 1 (2 versus 4 months; P=0.005) or grade≥2 (2 versus 6 months; P<0.001). Patients with grade≥2 rash showed higher rates of overall response (21% versus 7%; P<0.05) and disease control (84% versus 43%; P<0.05) versus grade<2. CONCLUSIONS: This study prospectively confirms the relationship between rash and longer OS in unresectable locally advanced/metastatic pancreatic cancer treated with erlotinib plus gemcitabine.

Recommendations and expert opinion on the treatment of locally advanced rectal cancer in Spain.

In Spain 22,000 new cases of colorectal cancer are diagnosed each year, with 13,075 deaths resulting from this disease. Around 70% of colorectal cancers are localised in the colon and 30% in the rectum. A group of Spanish experts established recommendations on what would be the best strategy in the treatment of locally advanced rectal cancer (LARC). Adequate assessment of local tumour extension, including high-resolution magnetic resonance imaging and endorectal ultrasound, is essential for successful treatment. The three cornerstones in the treatment of LARC are surgery, radiotherapy and chemotherapy. Most patients will need a total mesorectal excision (TME). Preoperative chemo-radiotherapy (CRT) is preferred for the majority of patients with T3/T4 disease and/or regional node involvement, and adjuvant chemotherapy is recommended after a patient-sharing decision. Capecitabine, after showing a trend in improved downstaging in neoadjuvant stratum and the convenience of its oral administration, represents an alternative to 5-FU as perioperative treatment of LARC.

Multidisciplinary approach and multimodal therapy in resected pancreatic cancer. Observational study.

OBJECTIVE: Analysis and evaluation of a multidisciplinary approach, postoperative results and survival of a group of patients with resected pancreatic cancer after a multimodal therapy. DESIGN: DESCRIPTIVE, prospective and observational study. PATIENTS: Between January 2004 and December 2004, 124 patients with pancreatic cancer were evaluated. In 30 patients pancreatic resection was performed, and they are the object of this study. Results of preoperative evaluation, postoperative morbidity and mortality, and long term survival were studied. RESULTS: Diagnostic evaluation was completed in ambulatory basis in 20% of the patients. In 63% of cases, admission was done in the same day of surgery. In 3 patients (9%), tumor resection was not achieved, therefore, concordance between radiological and surgical resectability rate was 91%. Resectability rate was 24.1%. Surgical Mortality was 3.3%, with a global morbidity rate of 56.6%. Survival at one, two, three and, four years was 76.2%, 56.3%, 43%, y 27.3% respectively. CONCLUSIONS: Technological development and coordination of efforts in multidisciplinary teams offer an accurate evaluation of tumor involvement, and may reduce the number of laparotomies without tumor resection. The application of a systematic and generalized multimodal treatment in pancreatic cancer is progressively showing a tendency of progressive increase in resectability and survival rates in pancreatic cancer.

Evaluación multidisciplinaria y tratamiento multimodal del cáncer de páncreas resecado. Estudio observacional / No disponible

Objetivo: analizar la evaluación del abordaje multidisciplinario de un grupo de pacientes con cáncer de páncreas resecado, los resultados postoperatorios y la supervivencia tras la aplicación de un tratamiento multimodal. Diseño: estudio descriptivo prospectivo observacional. Pacientes: entre enero de 2004 y diciembre 2009 se evaluaron 124 pacientes con cáncer de páncreas. De ellos, se realizó la resección pancreática con intención curativa en 30 casos que constituyen el objeto del estudio. Se analizaron los resultados del estudio preoperatorio de extensión tumoral, la morbi-mortalidad postoperatoria, y la supervivencia. Resultados: la evaluación diagnóstica se hizo en régimen ambulatorio en el 20% de los pacientes. En el 63% de los casos, el ingreso fue el mismo día de la intervención. En 3 pacientes intervenidos no se consiguió realizar la resección del tumor (9%), por lo que la tasa de concordancia entre la resecabilidad radiológica y la quirúrgica fue del 91%. La tasa de resecabilidad quirúrgica fue del 24,1%. La mortalidad quirúrgica de la serie fue de un 3,3%, con una morbilidad global del 56,6%. La supervivencia al año, dos, tres y cuatro años fue del 76,2%, 56,3%, 43%, y 27,3% respectivamente. Conclusiones: el desarrollo tecnológico y la evaluación multidisciplinar coordinada, permite realizar una evaluación precisa de la extensión tumoral, y puede reducir el número de laparotomías sin resección del tumor. Con la aplicación de una terapia multimodal sistemática combinada, la resecabilidad quirúrgica y la supervivencia a medio y largo plazo parece que están aumentando de forma progresiva(AU)

Undetected acute aortic dissection in a patient referred for primary coronary angioplasty: a successful treatment of perioperative bleeding after abciximab administration.

The authors describe a case of an acute aortic dissection in a Japanese woman with long-lasting hypertension, who was referred to our cath lab for primary percutaneous coronary intervention because of an ECG feature of acute inferior myocardial infarction and systemic hypotension. A successful treatment of perioperative bleeding followed a missed diagnosis in the early stages and abciximab administration.

Evaluation of systolic blood pressure control in elderly patients with isolated systolic hypertension.

The aim of this retrospective study was the evaluation of systolic blood pressure (SBP) control in elderly patients (pts) with isolated systolic hypertension (ISH). We assessed SBP control (i.e. average of 2 clinic BP measurements < 140 mmHg) in 152 pts (44 M, 108 F, 75 +/- 6 years) with ISH (149/84 +/- 17/6 mmHg), treated for at least 3 months by general practitioners or specialists with treatments of their choice. Most antihypertensive drugs were used at starting doses in monotherapy or combination treatment, as usual in clinical practice. ECG was abnormal in 82/152 pts (54.0%). All pts were divided in 2 groups according to SBP control. The 2 groups were compared by chi-square test for categorical variables and by Mann-Whitney test for quantitative variables. A p value < 0.05 was considered statistically significant. The global SBP control rate was 41.4% (63/152 pts). BP was higher in pts with poor SBP control, as expected, but the 2 groups were similar for sex distribution, age, prevalence of other cardiovascular risk factors and type of care (general practitioner or specialist). Pts with poor SBP control had a higher prevalence of abnormal ECG tracings (p = 0.003), a lower prevalence of combination regimes (p = 0.007) and prescriptions of dihydropyridine calcium antagonists or thiazide diuretics (p = 0.006). Global SBP control rate in our retrospective study in pts with ISH was unsatisfactory. Use of dihydropyridines or thiazides, drugs of choice in the management of ISH according to ESH/ESC and JNCVII guidelines, as single drugs or in combination regimes, can improve BP control and prevent cardiac damage.
