Background Improvements in local control are required when using preoperative chemoradiation for cT4 or advanced cT3 rectal cancer. There is therefore a need to explore more effective schedules. Patients and methods Patients with fixed cT3 or cT4 cancer were randomised either to 5x5 Gy and three cycles of FOLFOX4 (group A) or to 50.4 Gy in 28 fractions combined with two 5-day cycles of bolus 5-Fu 325 mg/m2/day and leucovorin 20 mg/m2/day during the first and fifth week of irradiation along with five infusions of oxaliplatin 50 mg/m2 once weekly (group B). The protocol was amended in 2012 to allow oxaliplatin to be then foregone in both groups. Results Of 541 entered patients, 515 were eligible for analysis; 261 in group A and 254 in group B. Preoperative treatment acute toxicity was lower in group A than group B, p=0.006; any toxicity being respectively 75% vs. 83%, grade III-IV 23% vs. 21% and toxic deaths 1% vs. 3%. R0 resection rates (primary endpoint) and pathological complete response rates in groups A and B were respectively 77% vs. 71%, p=0.07 and 16% vs. 12%, p=0.17. The median follow-up was 35 months. At 3 years, the rates of overall survival and disease-free survival in groups A and B were respectively 73% vs. 65%, p=0.046 and 53% vs. 52%, p=0.85, together with the cumulative incidence of local failure and distant metastases being respectively 22% vs. 21%, p=0.82 and 30% vs. 27%, p=0.26. Postoperative and late complications rates in group A and group B were respectively 29% vs. 25%, p=0.18 and 20% vs. 22%, p=0.54. Conclusions No differences were observed in local efficacy between 5x5 Gy with consolidation chemotherapy and long-course chemoradiation. Nevertheless, an improved overall survival and lower acute toxicity favours the 5x5 Gy schedule with consolidation chemotherapy.

Background: Early recognition of patients who have developed anastomotic leakage (AL) after colorectal surgery is crucial for the successful treatment of this complication. The aim of this study was to assess the usefulness of the assessment of procalcitonin (PCT) and interleukin-6 (IL-6) levels in the prognosis of AL.Methods: This observational study included 157 patients who underwent major elective colorectal surgery. The most common indications for surgery were cancer and inflammatory bowel diseases. Serum samples were obtained directly before surgery (D0) and 1 day (D1) after surgery, and the relationships between the serum concentrations of PCT and IL-6 and development of AL were assessed.Results: In total, 10.2% of patients developed post-surgical infections due to AL. PCT levels on D1 were significantly higher in patients who developed AL [2.73 (1.40–4.62)] than in those who recovered without complications [0.2 (0.09–0.44)]. The area under the ROC curve for PCT on D1 was 0.94, 95% CI (0.89–0.98). The sensitivity and specificity of the prediction of an infection were 87% and 87%, respectively, for PCT on D1, which was higher than 1.09 ng/mL. The increase in PCT concentration between D0 and D1 was significantly higher in patients with AL (p<0.001). Patients who developed AL had higher concentrations of IL-6 on D1, but the difference was not significant (p=0.28).Conclusions: This study confirms that surgical trauma increases serum PCT concentrations and that the concentration of PCT on D1 can predict AL after colorectal surgery. However, IL-6 is not a good early marker for developing AL.

Despite the growing experience of bariatric surgeons in performing laparoscopic sleeve gastrectomy, the number of complications involving staple line leaks remains constant. Hence a solution to avoid such complications is still sought. A defect of the staple line may be the consequence of an...
The present case study reports a case of chronic cough and cough syncope associated with frequent premature ventricular complexes (PVCs).Careful analysis of cough-related symptoms and ECG monitoring led to the suspicion of PVC-induced cough. A coincidence between PVCs and episodes of cough was also documented by a portable multichannel recorder. Moreover, Doppler echocardiography revealed a PVC-induced transient increase in the pulmonary artery blood flow.After exclusion of other possible aetiologies, complete relief of chronic cough and cough syncope was achieved by radiofrequency ablation of the arrhythmogenic focus located in the right ventricular outflow tract.Premature ventricular complexes should be considered as a cause of chronic cough and cough syncope and an interdisciplinary cooperation can lead to successful diagnosis and treatment of this condition.
Estrogen affects adipose tissue function. Therefore, this study aimed at assessing changes in the transcriptional activity of estrogen receptor (ER) α and β genes (ESR1 and ESR2, respectively) in the adipose tissues of obese individuals before and after weight loss and verifying whether epigenetic mechanisms were involved in this phenomenon. ESR1 and ESR2 mRNA and miRNA levels were evaluated using real-time PCR in visceral (VAT) and subcutaneous adipose tissue (SAT) of 78 obese (BMI > 40 kg/m2) and 31 normal-weight (BMI = 20–24.9 kg/m2) individuals and in 19 SAT samples from post-bariatric patients. ESR1 and ESR2 methylation status was studied using the methylation-sensitive digestion/real-time PCR method. Obesity was associated with a decrease in mRNA levels of both ERs in SAT (p < 0.0001) and ESR2 in VAT (p = 0.0001), while weight loss increased ESR transcription (p < 0.0001). Methylation levels of ESR1 and ESR2 promoters were unaffected. However, ESR1 mRNA in the AT of obese subjects correlated negatively with the expression of hsa-miR-18a-5p (rs = −0.444), hsa-miR-18b-5p (rs = −0.329), hsa-miR-22-3p (rs = −0.413), hsa-miR-100-5p (rs = −0.371), and hsa-miR-143-5p (rs = −0.289), while the expression of ESR2 in VAT correlated negatively with hsa-miR-576-5p (rs = −0.353) and in SAT with hsa-miR-495-3p (rs = −0.308). In conclusion, obesity-associated downregulation of ER mRNA levels in adipose tissue may result from miRNA interference.
