Cocoa as immunomodulatory agent: an update.

Cocoa is rich in polyphenols, mainly flavonoids, which correlate with several health benefits mediated by their antioxidant, anti-inflammatory and immunomodulatory properties. Cocoa and chocolate consumption have been reported to impact the regulation of the immune system, both in preclinical studies and in human trials. The mechanisms for immunomodulation can involve different effects of cocoa polyphenols on the immune system, acting as anti-inflammatory, antioxidant and anti-allergic agents, as well as the direct influence of cocoa on innate and acquired immunity, with cytokines production and activation of both lymphocyte-dependent and -independent pathways. Cocoa intake has been also correlated to changes in gut microbiota ecology and composition, also affecting the intestinal immune system. This review summarises the updates of the last two decades on cocoa as immunomodulatory agent and explores the health-related benefits of cocoa and chocolate intake.

Influence of simultaneous liver and peritoneal resection on postoperative morbi-mortality and survival in patients with colon cancer treated with surgical cytoreduction and intraperitoneal hyperthermic chemotherapy. / Influencia de la resección hepática y peritoneal simultánea, en la morbimortalidad y supervivencia de los pacientes con cáncer de colon intervenidos mediante cirugía citorreductora con quimioterapia intraperitoneal hipertérmica.

INTRODUCTION: Cytoreductive surgery plus intraperitoneal hyperthermic chemotherapy (HIPEC) has recently been established as the treatment of choice for selected patients with peritoneal carcinomatosis of colonic origin. Until recently, the simultaneous presence of peritoneal and hepatic dissemination has been considered a contraindication for surgery. The aim of this paper is to analyze the morbidity, mortality and survival of patients with simultaneous peritoneal and hepatic resection with HIPEC for peritoneal carcinomatosis secondary to colon cancer. METHODS: Between January 2010 and January 2015, 61 patients were operated on, 16 had simultaneous peritoneal and hepatic dissemination (group RH+), and 45 presented only peritoneal dissemination (group RH-). RESULTS: There were no differences between the groups in terms of demographic data, length of surgery and extension of peritoneal disease. Postoperative grade III-V complications were significantly higher in the RH+ group (56.3 vs. 26.6%; P=.032). For the whole group, mortality rate was 3.2% (two patients in group RH-, and none in group RH+). Patients with liver resection had a longer postoperative stay (14.4 vs. 23.1 days) (P=.027). Median overall survival was 33 months for RH-, and 36 for RH+ group. Median disease-free survival was 16 months for RH-, and 24 months for RH+ group. CONCLUSIONS: Simultaneous peritoneal cytoreduction and hepatic resection resulted in a significantly higher Clavien grade III-V morbidity and a longer hospital stay, although the results are similar to other major abdominal interventions. The application of multimodal oncological and surgical treatment may obtain similar long-term survival results in both groups.

Outcomes of an enhanced recovery after surgery programme for pancreaticoduodenectomy.

BACKGROUND: Enhanced recovery after surgery (ERAS) has demonstrated in colorectal surgery a reduction in morbidity and length of stay without compromising security. Experience with ERAS programs in pancreatoduodenectomy (PD) is still limited. The aims of this study were first to evaluate the applicability of an ERAS program for PD patients in our hospital, and second to analyze the postoperative results. METHODS: A retrospective study using a prospectively maintained database identified 41 consecutive PD included in an ERAS program. Key elements studied were early removal of tubes and drainages, early oral feeding and early mobilization. Variables studied were mortality, morbidity, perioperative data, length of stay, re-interventions and inpatient readmission. This group of patients was compared with an historic control group of 44 PD patients with a standard postoperative management. RESULTS: A total of 85 pancreatoduodenectomies were analyzed (41 patients in the ERAS group, and 44 patients in the control group. General mortality was 2.4% (2 patients) belonging to the control group. There were no statistical differences in mortality, length of stay in intensive care, reoperationss, and readmissions. ERAS group had a lower morbidity rate than the control group (32 vs. 48%; P=.072), as well as a lower length of stay (14.2 vs. 18.7 days). All the key ERAS proposed elements were achieved. CONCLUSIONS: ERAS programs may be implemented safely in pancreaticoduodenectomy. They may reduce the length of stay, unifying perioperative care and diminishing clinical variability and hospital costs.

Screw length in the guided growth method.

BACKGROUND: The appearance of the 8-plate as a method for hemiepiphysiodesis has renewed the interest for the use of this technique. However, many questions remain unanswered about the way of action of the guided growth method. Although screw length has been said to play no role, to our knowledge, no clinical or experimental evidence exists. METHODS: An experimental prospective randomized study with 40 WNZ Rabbits aged 8 weeks was conducted. Four experimental groups were established. Each tibia was randomly allocated to one of the following groups: Staples (group 1), 8-plate either using self-taping screws of 9 mm (group 2), or 5 mm lengths (groups 3) and control (group 4). Radiological assessment of the tibial deformity was done in a weekly fashion, and ALDA (articular line-diaphyseal angle) variations at 6 weeks were used as the control variable. RESULTS: The 8-plate as a whole produced a significant bigger deformity than the staples (10°). No significant differences between the two models of the 8-plate were found along the study (3.7°). CONCLUSIONS: The 8-plate has shown to be more efficient in producing angular deformity than staples. However, the length of the screw has showed no role in the 8-plate function.
