Diabetic nephropathy is now the main cause of end-stage renal disease. The mechanisms leading tothe development and progression of renal injury are not well known. Therefore, it is very important to f ind new pathogenic pathways to provide opportunities for early diagnosis and targets for novel treatments. At the present time, we know that activation of innate immunity with development of a chronic low grade inflammatory response is a recognized factor in the pathogenesis of diabetic nephropathy. Numerous experimental and clinical studies have shown the participation of different inflammatory molecules and pathways in the pathophysiology of this complication. 展开更多

Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections(alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum-a major contributor to fracture healing- in the femoral neck. In extracapsularfractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients. 展开更多

AIM To demonstrate the non-inferiority(15% non-inferiority limit) of monotherapy with tenofovir disoproxil fumarate(TDF) vs the combination of lamivudine(LAM) plus adefovir dipivoxil(ADV) in the maintenance of virologic response in patients with chronic hepatitis B(CHB) and prior failure with LAM.METHODS This study was a Phase IV prospective, randomized, open, controlled study with 2 parallel groups(TDF and LAM+ADV) of adult patients with hepatitis B e antigen(HBe Ag)-negative CHB, prior failure with LAM, on treatment with LAM+ADV for at least 6 mo, without prior resistance to ADV and with an undetectable viral load at the start of the study, in 14 Spanish hospitals. The follow-up time for each patient was 48 wk after randomization, with quarterly visits in which the viral load, biochemical and serological parameters, adverse effects, adherence to treatment and consumption of hospital resources were analysed.RESULTS Forty-six patients were evaluated [median age: 55.4 years(30.2-75.2); 84.8% male], including 22 patients with TDF and 24 with LAM+ADV. During study development, hepatitis B virus DNA(HBV-DNA) remained undetectable, all patients remained HBe Ag negative, and hepatitis B surface antigen(HBs Ag) positive. Alanine aminotransferase(ALT) values at the end of the study were similar in the 2 groups(25.1± 7.65, TDF vs 24.22 ± 8.38, LAM+ADV, P = 0.646). No significant changes were observed in creatinine or serum phosphorus values in either group. No significant differences between the 2 groups were noted in the identification of adverse effects(AEs)(53.8%, TDF vs 37.5%, LAM+ADV, P = 0.170), and none of the AEs which occurred were serious. Treatment adherence was 95.5% and 83.3% in the TDF and the LAM+ADV groups, respectively(P = 0.488). The costs associated with hospital resource consumption were significantly lower with the TDF treatment than the LAM+ADV treatment(€4943 ± 1059 vs €5811 ± 1538, respectively, P < 0.001).CONCLUSION TDF monotherapy proved to be safe and not inferior to the LAM+ADV combinat 展开更多

BACKGROUND Helicobacter pylori(H.pylori)is a widespread microorganism related to gastric adenocarcinoma(AC).In contrast,it has been reported that an inverse association exists between H.pylori infection and esophageal carcinoma.The mechanisms underlying this supposedly protective effect remain controversial.AIM To determine the prevalence of H.pylori infection in esophageal carcinoma patients,we performed a retrospective observational study of esophageal tumors diagnosed in our hospital.METHODS We retrospectively reviewed the prevalence of H.pylori infection in a cohort of patients diagnosed with esophageal carcinoma.Concomitant or previous proton pump inhibitor(PPI)usage was also recorded.RESULTS A total of 89 patients with esophageal carcinoma(69 males,77.5%),with a mean age of 66 years(range,26-93 years)were included.AC was the most frequent pathological variant(n=47,52.8%),followed by squamous cell carcinoma(n=37,41.6%).Fourteen ACs(29.8%)originated in the gastroesophageal junction and 33(70.2%)in the esophageal body.Overall,54 patients(60.7%)presented at stages III and IV.Previous H.pylori infection occurred only in 4 patients(4.5%),3 with AC(6.3%of all ACs)and 1 with squamous cell carcinoma(2.7%of all squamous cell tumors).All patients with previous H.pylori infection had stage III-IV.Only one patient had received prior H.pylori eradication therapy,whereas 86(96.6%)had received previous or concomitant PPI treatment.CONCLUSION In our cohort of patients,and after histologic evaluation of paraffin-embedded primary tumors,we found a very low prevalence of previous H.pylori infection.We also reviewed the medical history of the patients,concluding that the majority had received or were on PPI treatment.The minimal prevalence of H.pylori infection found in this cohort of patients with esophageal carcinoma suggests a protective role. 展开更多

The current management therapies for hepatocellular carcinoma(HCC) patients are discussed in this review. Despite the development of new therapies, HCC remains a 'difficult to treat' cancer because HCC typically occurs in advanced liver disease or hepatic cirrhosis. The progression of multistep and multicentric HCC hampers the prevention of the recurrence of HCC. Many HCC patients are treated with surgical resection and radiofrequency ablation(RFA), although these modalities should be considered in only selected cases with a certain HCC number and size. Although there is a shortage of grafts, liver transplantation has the highest survival rates for HCC. Several modalities are salvage treatments; however, intensive care in combination with other modalities or in combination with surgical resection or RFA might offer a better prognosis. Sorafenib is useful for patients with advanced HCC. In the near future, HCC treatment will include stronger molecular targeted drugs, which will have greater potency and fewer adverse events. Further studies will be ongoing. 展开更多

The use of mesenchymal stem-cells(MSC)in cell therapy has received considerable attention because of their properties.These properties include high expansion and differentiation in vitro,low immunogenicity,and modulation of biological processes,such as inflammation,angiogenesis and hematopoiesis.Curiously,the regenerative effect of MSC is partly due to their paracrine activity.This has prompted numerous studies,to investigate the therapeutic potential of their secretome in general,and specifically their extracellular vesicles(EV).The latter contain proteins,lipids,nucleic acids,and other metabolites,which can cause physiological changes when released into recipient cells.Interestingly,contents of EV can be modulated by preconditioning MSC under different culture conditions.Among them,exposure to hypoxia stands out;these cells respond by activating hypoxia-inducible factor(HIF)at low O_(2) concentrations.HIF has direct and indirect pleiotropic effects,modulating expression of hundreds of genes involved in processes such as inflammation,migration,proliferation,differentiation,angiogenesis,metabolism,and cell apoptosis.Expression of these genes is reflected in the contents of secreted EV.Interestingly,numerous studies show that MSC-derived EV conditioned under hypoxia have a higher regenerative capacity than those obtained under normoxia.In this review,we show the implications of hypoxia responses in relation to tissue regeneration.In addition,hypoxia preconditioning of MSC is being evaluated as a very attractive strategy for isolation of EV,with a high potential for clinical use in regenerative medicine that can be applied to different pathologies. 展开更多

Objectives To analyze the clinical profile,adequacy of treatment with rivaroxaban and outcomes in octogenarians with atrial fibrillation(AF),taking rivaroxaban in clinical practice.Methods Observational and non-interventional study that included AF adults recruited from 79 Spanish centers,anticoagulated with rivaroxaban ≥ 6 months before being included.Data were analyzed according to age(≥ 80 vs.< 80 years) at baseline.Results Out of 1433 patients,453(31.6%) were octogenarians at baseline.Compared to younger patients,octogenarians had more comorbidities,higher CHA2DS2-VASc(4.5 ± 1.3 vs.3.0 ± 1.4;P < 0.001) and HAS-BLED scores(2.0 ± 1.0 vs.1.4 ± 1.0;P < 0.001).Overall,the dose of rivaroxaban was adequately prescribed in 83.4% of patients,but more frequently in the younger population(71.1% vs.89.1%;P = 0.039).After a mean follow-up of 2.2 ± 0.6 years,annual rates of stroke + systemic embolism + transient ischemic attack,MACE,cardiovascular death and major bleeding were 1.03%,1.24%,1.03% and 1.75%,respectively,in octogenarian patients.Except for progressive heart failure death and major bleeding,rates of outcomes in octogenarians were similar compared to younger patients.In octogenarians,the concomitant use of antiplatelet agents and non-severe dementia were independently associated with the development of ischemic stroke,whereas previous coronary revascularization and heart failure with MACE,and higher HAS-BLED score with major bleeding.Conclusions In clinical practice,around one third of patients taking rivaroxaban are octogenarians.These patients have many comorbidities and a high thromboembolic risk.Despite that,rates of adverse events remain low.Rivaroxaban is adequately prescribed in the majority of octogenarians. 展开更多

Decision-making based on artificial intelligence(AI)methodology is increasingly present in all areas of modern medicine.In recent years,models based on deep-learning have begun to be used in organ transplantation.Taking into account the huge number of factors and variables involved in donor-recipient(DR)matching,AI models may be well suited to improve organ allocation.AI-based models should provide two solutions:complement decision-making with current metrics based on logistic regression and improve their predictability.Hundreds of classifiers could be used to address this problem.However,not all of them are really useful for D-R pairing.Basically,in the decision to assign a given donor to a candidate in waiting list,a multitude of variables are handled,including donor,recipient,logistic and perioperative variables.Of these last two,some of them can be inferred indirectly from the team’s previous experience.Two groups of AI models have been used in the D-R matching:artificial neural networks(ANN)and random forest(RF).The former mimics the functional architecture of neurons,with input layers and output layers.The algorithms can be uni-or multi-objective.In general,ANNs can be used with large databases,where their generalizability is improved.However,they are models that are very sensitive to the quality of the databases and,in essence,they are black-box models in which all variables are important.Unfortunately,these models do not allow to know safely the weight of each variable.On the other hand,RF builds decision trees and works well with small cohorts.In addition,they can select top variables as with logistic regression.However,they are not useful with large databases,due to the extreme number of decision trees that they would generate,making them impractical.Both ANN and RF allow a successful donor allocation in over 80%of D-R pairing,a number much higher than that obtained with the best statistical metrics such as model for end-stage liver disease,balance of risk score,and survival outcomes following liver t 展开更多

BACKGROUND Surgical resection and radiofrequency ablation(RFA)represent two possible strategy in treatment of hepatocellular carcinoma(HCC)in Milan criteria.AIM To evaluate short-and long-term outcome in elderly patients(>70 years)with HCC in Milan criteria,which underwent liver resection(LR)or RFA.METHODS The study included 594 patients with HCC in Milan criteria(429 in LR group and 165 in RFA group)managed in 10 European centers.Statistical analysis was performed using the Kaplan-Meier method before and after propensity score matching(PSM)and Cox regression.RESULTS After PSM,we compared 136 patients in the LR group with 136 patients in the RFA group.Overall survival at 1,3,and 5 years was 91%,80%,and 76%in the LR group and 97%,67%,and 41%in the RFA group respectively(P=0.001).Diseasefree survival at 1,3,and 5 years was 84%,60%and 44%for the LR group,and 63%,36%,and 25%for the RFA group(P=0.001).Postoperative Clavien-Dindo IIIIV complications were lower in the RFA group(1%vs 11%,P=0.001)in association with a shorter length of stay(2 d vs 7 d,P=0.001).In multivariate analysis,Model for End-stage Liver Disease(MELD)score(>10)[odds ratio(OR)=1.89],increased value of international normalized ratio(>1.3)(OR=1.60),treatment with radiofrequency(OR=1.46),and multiple nodules(OR=1.19)were independent predictors of a poor overall survival while a high MELD score(>10)(OR=1.51)and radiofrequency(OR=1.37)were independent factors associated with a higher recurrence rate.CONCLUSION Despite a longer length of stay and a higher rate of severe postoperative complications,surgery provided better results in long-term oncological outcomes as compared to ablation in elderly patients(>70 years)with HCC in Milan criteria. 展开更多

In the new era of functional magnetic resonance imaging(MRI), the utility of chest MRI is increasing exponentially due to several advances, including absence of ionizing radiation, excellent tissue contrast and high capability for lesion characterization and treatment monitoring. The application of several of these diagnostic weapons in a multiparametric fashion enables to better characterize thymic epithelial tumors and other mediastinal tumoral lesions, accurate assessment of the invasion of adjacent structures and detection of pathologic lymph nodes and metastasis. Also, "do not touch lesions" could be identified with the associated impact in the management of those patients. One of the hotspots of the multiparametric chest MR is its ability to detect with acuity early response to treatment in patients with mediastinal malignant neoplasms. This has been related with higher rates of overall survival and progression free survival.Therefore, in this review we will analyze the current functional imaging techniques available(18 F-Fluorodeoxiglucose positron emission tomography/computed tomography, diffusion-weighted imaging, dynamic contrast-enhanced MRI, diffusion tensor imaging and MR spectroscopy) for the evaluation of mediastinal lesions, with a focus in their correct acquisition and post-processing. Also, to review the clinical applications of these techniques in the diagnostic approach of benign and malignant conditions of the mediastinum. 展开更多

The concept of oligometastatic disease was first described by Hellman and Weichselbaum in 1995. The mere insight of this concept led to the hypothesis that this disease may be cured using local ablative weapons. Surgery has already demonstrated this hypothesis. Surgery limitations, either technical or due to refusalor associated comorbidity, have led to implement alternative ablative options such as stereotactic body radiation therapy(SBRT). SBRT evolved from(stereotactic radiosurgery) because of the need to irradiate extracranial lesions and has been shown to be safe and effective. SBRT achieves local control rates ranging from 70%-90%, but highly variable survival rates depending on the group analyzed. Series with heterogeneous metastatic sites and tumor origin have reported 20% survival rates at 2-3 years, similar to those achieved with surgery. Despite its excellent results, SBRT still faces significant clinical challenges. Its optimal integration with systemic treatment is unknown, and response assessment is very difficult. However, the greatest challenge lies in selection of patients most likely to remain oligometastatic, those who will most benefit from the technique. Biomarkers, molecular signatures, that accurately predict the biological behavior of malignancy are needed. The expression profile of specific mi RNAs has been shown to have a potential in this regard. 展开更多

AIM To evaluate the rate of adverse events(AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers. METHODS Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of bleeding.CONCLUSION Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location. 展开更多

Extra virgin olive oil is characterized by its high content of unsaturated fatty acid residues in triglycerides,mainly oleic acid,and the presence of bioactive and antioxidant compounds.Its consumption is associated with lower risk of suffering chronic diseases and unwanted processes linked to aging,due to the antioxidant capacity and capability of its components to modulate cellular signaling pathways.Consumption of olive oil can alter the physiology of mesenchymal stem cells(MSCs).This may explain part of the healthy effects of olive oil consumption,such as prevention of unwanted aging processes.To date,there are no specific studies on the action of olive oil on MSCs,but effects of many components of such food on cell viability and differentiation have been evaluated.The objective of this article is to review existing literature on how different compounds of extra virgin olive oil,including residues of fatty acids,vitamins,squalene,triterpenes,pigments and phenols,affect MSC maintenance and differentiation,in order to provide a better understanding of the healthy effects of this food.Interestingly,most studies have shown a positive effect of these compounds on MSCs.The collective findings support the hypothesis that at least part of the beneficial effects of extra virgin olive oil consumption on health may be mediated by its effects on MSCs. 展开更多

Unfortunat... Hepatitis C virus (HCV) is a major health problem that leads to chronic hepatitis, cirrhosis and hepatocellular carcinoma, being the most frequent indication for liver transplantation in several countries. Unfortunately, HCV re-infects the liver graft almost invariably following reperfusion, with an accelerated history of recurrence, leading to 10%-30% of patients progressing to cirrhosis within 5 years of transplantation. In this sense, some groups have even advocated for not retransplanting this patients, as lower patient and graftoutcomes have been reported. However, the management of HCV recurrence is being optimized and several strategies to reduce post-transplant recurrence could improve outcomes, decrease the rate of re-transplantation and optimize the use of available grafts. Three moments may be the focus of potential actions in order to decrease the impact of viral recurrence: the pretransplant moment, the transplant environment and the post-transplant management. In the pre-transplant setting, it is not well established if reducing the pre transplant viral load affects the risk for HCV progression after transplant. Obviously, antiviral treatment can render the patient HCV RNA negative post transplant but the long-term benefit has not yet been fully established to justify the cost and clinical risk. In the transplant moment, factors as donor age, cold ischemia time, graft steatosis and ischemia/reperfusion injury may lead to a higher and more aggressive viral recurrence. After the transplant, discussion about immunosuppression and the moment to start the treatment (prophylactic, pre-emptive or once-confirmed) together with new antiviral drugs are of interest. This review aims to help clinicians have a global overview of posttransplant HCV recurrence and strategies to reduce its impact on our patients. 展开更多

We report an unusual pathological entity of a pseudoaneurysm of the right hepatic artery, which developed two years after the resection of a type 11 hilar cholangiocarcinoma and secondary to an excessive skeletonization for regional lymphadenectomy and neoadjuvant external-beam radiotherapy. After a sudden and massive hematemesis, a multidetector computed tomographic angiography (MDCTA) showed a hepatic artery pseudoaneurysm. Angiography with embolization of the pseudoaneurysm was attempted using microcoils with adequate patency of the hepatic artery and the occlusion of the pseudoaneurysm. A new episode of hematemesis 3 wk later revealed a partial revascularization of the pseudoaneurysm. A definitive interventional radiological treatment consisting of transarterial embolization (TAE) of the right hepatic artery with stainless steel coils and polyvinyl alcohol particles was effective and welltolerated with normal liver function tests and without signs of liver infarction. 展开更多

The second group performed a supervised training program at an adapted physical activitygym (Sgym), including aerobic and resistance training. The outcomes, collected at baseline and at the end of theprograms, included the 6-minute walking test, the peak oxygen consumption (VO_(2)peak) during a treadmill test,the 5-time sit-to-stand test, and blood pressure.RESULTSSeventeen patients agreed to participate and self-selected into the HBex (n = 9) and Sgym (n = 8) groups. Twopatients in the Sgym group dropped out because of familial problems. At baseline, patients in the HBex group weresignificantly older and had lower walking distance, VO_(2)peak, and lower limb strength. Primary outcome changeswere significantly greater in the HBex group than in the Sgym group (52 ± 23 m vs 8 ± 34;P = 0.005). No othersignificant differences between groups were observed. Both groups improved most of the outcomes in the withingroupcomparisons, with significant variations in VO_(2) peak.CONCLUSIONSix-month moderate-intensity supervised or low-intensity home-based training programs effectively improvedexercise capacity in KTRs. Gym-based programs combine aerobic and resistance training;however, in-homewalking may be proposed for frail KTRs. 展开更多

AIM: To investigate the prognostic significance of resting heart rate in patients with acute coronary syndrome (ACS), independent of other known factors. METHODS: Patients 40 years of age or older who had been admitted with acute coronary syndrome (ACS) to one of the 94 hospitals participating in the Prevalence of Peripheral Arterial Disease in Patients with Acute Coronary Syndrome (PAMISCA) study were included. Patients were divided into two groups based on their resting heart rate (HR ≥ or < 70 bpm). Complications were recording during a follow-up period of 1 year. RESULTS: There were 1054 ACS patients analyzed (43.5% with ST segment elevation and 56.5% without elevation). Mean age was 66.6 ± 11.7 years, 70.6% were male and 29.4% of subjects were female. During follow-up, more patients in the HR ≥ 70 bpm group were hospitalized for heart failure and they also had a higher mortality rate. In the multivariate analysis, a heart rate of ≥ 70 bpm was independently related to overall mortality during the follow-up period (hazard ratio 2.5; 95% confidence interval, 1.26-4.97, P = 0.009). CONCLUSION: A resting heart rate ≥ 70 bpm in patients who survive an ACS is an indicator of a high risk of suffering cardiovascular events during follow-up. 展开更多

BACKGROUND Sacubitril-valsartan has been shown to reduce hospitalizations and mortality in patients with heart failure(HF)and reduced ejection fraction.The PIONEER-HF trial demonstrated that initiation of the drug during acute HF hospitalization reduced NT-proBNP levels and a post-hoc analysis of the trial found a reduction in HF hospitalizations and deaths.Real-life studies in the elderly population are scarce.The aim of our study was to assess the effectiveness of sacubitril-valsartan versus angiotensin converting enzyme inhibitors(ACEI)in elderly patients who initiate this treatment during hospitalization for acute HF.METHODS We conducted a retrospective cohort study using the Spanish acute heart failure registry(RICA)comparing rehospitalizations and deaths at 3 months and 1 year among patients aged 70 years or older who had initiated treatment with sacubitrilvalsartan during hospitalization for acute HF versus those treated with ACEI.RESULTS One hundred and ninety-nine patients hospitalized between October 2016 and November 2020 were included,with a median age of 82 years and high rate of comorbidity.Of these,107 were treated with sacubitril-valsartan and 92 with ACEI.The adjusted OR for readmission for HF at 3 months was 0.906(95%CI:0.241-3.404)and for the combined variable readmission for HF or death at 3 months was 0.696(95%CI:0.224-2.167).The adjusted OR for HF readmission at one year was 0.696(95%CI:0.224-2.167).and for the combined variable HF readmission or death at one year 0.724(95%CI:0.325-1.612).CONCLUSION Treatment with sacubitril-valsartan initiated early in hospitalization for HF in elderly patients with high comorbidity was associated with a trend towards a reduction in readmissions and death due to HF compared to treatment with ACEI,which did not reach statistical significance either at 3 months or 1 year of follow-up. 展开更多

Polyarteritis nodosa(PAN) is one of the systemic vasculitis that affects the media wall of arteries of small and medium diameter. Diagnosis proves difficult due to the unspecific symptoms that dominate the clinical profile. Liver involvement is very diverse, ranging from the development of cirrhotic liver disease to acute abdomen presentation that requires surgery because of liver rupture. The management of these patients requires an expert multidisciplinary team. There are several cases in the literature that describe a sudden liver rupture as the first manifestation of a PAN. In this paper we present the case of a 75 years old patient without any previous disease, who is subjected to major hepatic resection for spontaneous liver rupture. 展开更多
