Long-Term Weight Loss Results, Remission of Comorbidities and Nutritional Deficiencies of Sleeve Gastrectomy (SG), Roux-En-Y Gastric Bypass (RYGB) and One-Anastomosis Gastric Bypass (OAGB) on Type 2 Diabetic (T2D) Patients

Producción CientíficaThis study aimed to compare the long-term weight loss results, remission of comorbidities and nutritional deficiencies of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB) and One-Anastomosis gastric bypass (OAGB) on type 2 diabetic (T2D) patients. Patients and Methods: A retrospective analysis of all the morbidly obese and diabetic patients undergoing SG, RYGB, and OAGB as primary bariatric procedures between February 2010 and June 2015 was performed. Anthropometric parameters, remission of comorbidities, nutritional deficiencies and supplementation requirements at 1, 2 and 5 years’ follow-up were monitored. Patients lost to follow-up 5 years after surgery were excluded from the analysis. Results: 358 patients were included. The follow-up rate was 84.8%. Finally, 83 SG, 152 RYGB, and 123 OAGB patients were included in the analysis. OAGB obtained significantly greater weight loss and remission of dyslipidemia than the other techniques. There was a trend towards greater T2D and hypertension remission rate after OAGB, while fasting glucose and glycated hemoglobin levels were significantly lower after OAGB. There were no significant differences in hemoglobin or protein levels between groups. SG obtained lower iron deficiencies than the other techniques, while there were no significant differences in other nutritional deficiencies between groups. Conclusion: OAGB obtained greater weight loss and remission of dyslipidemia than RYGB or SG. Excluding lower iron deficiency rates after SG, there were no significant differences in the development of nutritional deficiencies between groups

Changes in lipid profile, body weight variables and cardiovascular risk in obese patients undergoing one-anastomosis gastric bypass

Producción CientíficaMorbid obesity has a direct impact on the development of cardiovascular disease. One-anastomosis gastric bypass (OAGB) is an effective surgical technique for the control of body weight and the reduction of cardiovascular risk. This work examines the change in weight loss, lipid profile and cardiovascular risk in 100 patients (71 women, 29 men), mean age 42.61 ± 11.33 years at 3, 6, 9, 12, 18 and 24 months after OAGB. At 24 months post-surgery, mean body weight was significantly reduced compared to pre-operative values (116.75 ± 22.19 kg vs. 69.66 ± 13.07 kg), as were mean total cholesterol (201.86 ± 44.60 mg/dL vs. 172.99 ± 32.26 mg/dL), LDL (Low-Density Lipoprotein) cholesterol (126.90 ± 39.81 mg/dL vs. 96.28 ± 26.99 mg/dL), triglycerides (138.05 ± 78.45 mg/dL vs. 76.04 ± 30.34 mg/dL) and cardiovascular risk (total cholesterol/HDL (High-Density Lipoprotein) cholesterol: 4.32 ± 1.24 vs. 2.93 ± 0.71), while the mean HDL cholesterol concentration was significantly higher (49.09 ± 14.16 mg/dL vs. 61.98 ± 14.86 mg/dL) (all p < 0.001). In conclusion, OAGB surgery led to significant reductions in body weight, a significant improvement in the lipid profile, and a reduction in cardiovascular risk

Assessment of risk factors associated with cardiovascular diseases in overweight women

Producción CientíficaThe assessment of anthropometric variables has been shown to be useful as a predictor of cardiovascular risk in overweight and obese patients. The aim of this study was to determine the usefulness of the relationship between breast volume and body mass index as an indicator of cardiovascular risk in premenopausal women with overweight and mild obesity. A prospective observational study of 93 premenopausal women was performed. Evaluation of anthropometric measures included age, body mass index, waist and hip circumferences, breast projection, and ptosis. Cardiovascular risk factors were evaluated using the Framingham cardiovascular risk score, the triglycerides/HDL cholesterol ratio and the waist-hip ratio. Ninety-three women were included, with a mean 36.4 ± 7.5 years. Mean BMI was 27.3 ± 1.9 kg/m2, waist-to-Hip ratio was 0.8 ± 0.07, and mammary volume was 1045 ± 657.4 cm3. Mean body fat mass was 30.6 + 3.6% and mean visceral fat was 6.6 + 3.2%. The mean triglycerides to HDL ratio was 1.7 ± 0.8 and waist-to-hip ratio was 0.8 ± 0.07. Breast volume related to body mass index can be used as a predictor of cardiovascular risk in premenopausal women who are overweight and mildly obese

Implications of professional occupation related to obesity in patients undergoing bariatric surgery

Producción CientíficaObesity is an epidemic with severe consequences on the professional development of patients. Bariatric surgery has proven to be a safe treatment with effective results in weight control. The aim of this study is to assess the implications of professional occupation in relation to the development of obesity and weight changes after bariatric surgery. We analyzed 500 obese patients (77.8% women, 22.2% men) who underwent one anastomosis gastric bypass surgery at the Centre of Excellence for the Study and Treatment of Obesity and Diabetes (2014–2019), assessing the influence of professional occupation on body composition and evolution of weight loss up to two years after surgery. Preoperative obesity type III and IV was higher in men than in women (45.9–19.8% vs. 43.7–9.5%; respectively). Prevalent clinical history in women was depression (46.7%), varicose veins (35.6%), and thyroid disease (9.7%), while in men it was respiratory failure (98.2%), high blood pressure (56.8%), hepatic steatosis (82%). Postoperative weight loss was effective in every professional field, reaching normal weight values from 12 months after surgery

Impact of preoperative total proteins and glycated hemoglobin on recurrences after early colorectal cancer

Producción CientíficaBackground: The outcome of colorectal cancer is mostly based on TNM classification. There are several factors determining that patients with the same tumoral stage present different outcomes. The nutritional status has been related to the immunological response and may affect the oncologic results. The purpose of this study was to determine if preoperative nutritional parameters may predict the oncologic outcome in patients with early colorectal cancer. Methods: A prospective observational study of patients undergoing elective surgery for colorectal cancer was performed with stage I. Preoperative nutritional assessment included glycemic and lipid profiles, total proteins, and albumin levels. These parameters were correlated with tumoral recurrence during a follow-up of at least 24 months. Results: During the period of study, 744 patients were operated on and 228 (30.6%) followed the inclusion criteria for this study. Recurrence rate was 5.7% (13 patients). Patients with hypoproteinemia showed a 7.8-fold greater risk of recurrence during the first 24 months after surgery [OR 7.8 (CI95% 1.3–48), p = 0.012]. Patients with glycated hemoglobin levels (HbA1c) > 6.2% showed a 2.3 increased risk of recurrence [OR 2.3 (CI95% 1.1–4.7; p = 0.01]. Conclusions: Preoperative values of total proteins and HbA1c correlate with the recurrence rate in early colorectal cancer

Rationale for the Use of Radiation-Activated Mesenchymal Stromal/Stem Cells in Acute Respiratory Distress Syndrome

We have previously shown that the combination of radiotherapy with human umbilical-cord-derived mesenchymal stromal/stem cells (MSCs) cell therapy significantly reduces the size of the xenotumors in mice, both in the directly irradiated tumor and in the distant nonirradiated tumor or its metastasis. We have also shown that exosomes secreted from MSCs preirradiated with 2 Gy are quantitatively, functionally and qualitatively different from the exosomes secreted from nonirradiated mesenchymal cells, and also that proteins, exosomes and microvesicles secreted by MSCs suffer a significant change when the cells are activated or nonactivated, with the amount of protein present in the exosomes of the preirradiated cells being 1.5 times greater compared to those from nonirradiated cells. This finding correlates with a dramatic increase in the antitumor activity of the radiotherapy when is combined with MSCs or with preirradiated mesenchymal stromal/stem cells (MSCs*). After the proteomic analysis of the load of the exosomes released from both irradiated and nonirradiated cells, we conclude that annexin A1 is the most important and significant difference between the exosomes released by the cells in either status. Knowing the role of annexin A1 in the control of hypoxia and inflammation that is characteristic of acute respiratory-distress syndrome (ARDS), we designed a hypothetical therapeutic strategy, based on the transplantation of mesenchymal stromal/stem cells stimulated with radiation, to alleviate the symptoms of patients who, due to pneumonia caused by SARS-CoV-2, require to be admitted to an intensive care unit for patients with life-threatening conditions. With this hypothesis, we seek to improve the patients’ respiratory capacity and increase the expectations of their cure.Ministerio de Economia y Competividad MINECO: SAF2012-40011-C02-02 SAF2015-70520-R RTICC RD12/0036/002

Hepatitis C virus molecular evolution: Transmission, disease progression and antiviral therapy

Hepatitis C virus (HCV) infection represents an important public health problem worldwide. Reduction of HCV morbidity and mortality is a current challenge owned to several viral and host factors. Virus molecular evolution plays an important role in HCV transmission, disease progression and therapy outcome. The high degree of genetic heterogeneity characteristic of HCV is a key element for the rapid adaptation of the intrahost viral population to different selection pressures (e.g., host immune responses and antiviral therapy). HCV molecular evolution is shaped by different mechanisms including a high mutation rate, genetic bottlenecks, genetic drift, recombination, temporal variations and compartmentalization. These evolutionary processes constantly rearrange the composition of the HCV intrahost population in a staging manner. Remarkable advances in the understanding of the molecular mechanism controlling HCV replication have facilitated the development of a plethora of direct-acting antiviral agents against HCV. As a result, superior sustained viral responses have been attained. The rapidly evolving field of anti-HCV therapy is expected to broad its landscape even further with newer, more potent antivirals, bringing us one step closer to the interferon-free era.Fil: Preciado, María Victoria.

Phenolic compounds in extra virgin olive oil stimulate human osteoblastic cell proliferation

In this study, we aimed to clarify the effects of phenolic compounds and extracts from different extra virgin olive oil (EVOO) varieties obtained from fruits of different ripening stages on osteoblast cells (MG-63) proliferation. Cell proliferation was increased by hydroxytyrosol, luteolin, apigenin, p-coumaric, caffeic, and ferulic acids by approximately 11–16%, as compared with controls that were treated with one vehicle alone, while (+)-pinoresinol, oleuropein, sinapic, vanillic acid and derivative (vanillin) did not affect cell proliferation. All phenolic extracts stimulated MG-63 cell growth, and they induced higher cell proliferation rates than individual compounds. The most effective EVOO phenolic extracts were those obtained from the Picual variety, as they significantly increased cell proliferation by 18–22%. Conversely, Arbequina phenolic extracts increased cell proliferation by 9–13%. A decline in osteoblast proliferation was observed in oils obtained from olive fruits collected at the end of the harvest period, as their total phenolic content decreases at this late stage. Further research on the signaling pathways of olive oil phenolic compounds involved in the processes and their metabolism should be carried out to develop new interventions and adjuvant therapies using EVOO for bone health (i.e.osteoporosis) in adulthood and the elderly
