HLA-G is a nonclassical MHC-Class I molecule whose expression, along the feto-maternal barrier contributes towards tolerance of the semiallogeneic fetus during pregnancy. In light of its inhibitory properties, recent research has established HLA-G involvement in mechanisms responsible for directing allogeneic immune responses towards tolerance during allogeneic situations such as organ transplantation. Here, we critically review the data supporting the tolerogenic role of HLA-G in organ transplantation, the various factors influencing its expression, and the introduction of novel humanized mouse models that are one of the best approaches to assess the utility of HLA-G as a therapeutic tool in organ transplantation. PURPOSE To present a new anterior subtenonian anesthesia approach in the area of the future filtration bleb and its influence on medium term surgical success. MATERIAL AND METHODS Retrospective study of 97 surgeries, deep sclerectomy (DE) or phaco-deep sclerectomy (PHACO-DS), were performed in patients with open angle glaucoma (OAG) comparing our modified "underbleb" subtenonian anesthesia (USA) (n=58) versus a control group under peribulbar anesthesia (PA) (n=38). Main outcomes were intraocular pressure (IOP), number of antiglaucomatous drugs and total and qualificated success, compared during 1, 3, 6, 12, 18 and 24 months follow up after glaucoma surgery. RESULTS Both groups were comparable in terms of age, gender, surgical technique, number of antiglaucoma drugs and preoperative IOP. The IOP in the USA group decreased as in PA control group without statistical significant differences except at 24 months, where the IOP was 2mm lower (14.83 ± 2.87 vs. 17.61 ± 4.27 (P=.009). This happened for both, DS and PHACO-DS surgeries. The number of postoperative drugs was lower at 3, 6, and 18 months but without statistically significant diferences. Total success rate at 24 months was higher in the USA group respect AP control group (62.5% vs. 51.6) as well as partial success (100% vs. 71%). CONCLUSION Our new USA anesthetic technique does not have a negative impact in DS medium-term surgical success, even it could contribute to a longer-term improvement. The effects of the many biochemical and physiologic changes of pregnancy on the dose-response relationship of drugs administered to pregnant women are poorly understood. The dose-response relationship is affected by pharmacokinetics, or what the body does to a drug, and pharmacodynamics, or what a drug does to the body. Insights into the potential effects of the changes of pregnancy on one aspect of the dose-response relationship of a drug can be obtained by studying the pharmacokinetics of the drug in the various stages of pregnancy and the postpartum period. There are several available approaches to studying pharmacokinetic changes in pregnancy. Single trough screening studies can provide qualitative estimates of elimination clearance, which with the dosing rate determines the steady-state drug concentration, throughout pregnancy and into the postpartum period. Population pharmacokinetic studies such as two stage pharmacokinetic studies and studies using a nonlinear mixed effects pharmacokinetic modeling approach can characterize pharmacokinetic changes more rigorously. BACKGROUND & AIMS Adequate nutrition from which amino acids are part gives us protection against infectious or metabolic diseases. In particular, glycine has immunomodulatory properties and is a secretagogue of insulin. However, its absorption rate or plasma levels are impaired in bacterial infection or high glucose levels. The aim of this study was to evaluate the association between glycine and insulin plasma levels in patients with pulmonary tuberculosis (PTB) and type 2 diabetes mellitus (DM2). METHODS Plasma levels of insulin and glycine were determined in four groups 1) patients with PTB; 2) patients with PTB-DM2; 3) household contacts with DM2 (C-DM2), and 4) healthy household contacts (H-C). ATR inhibitor 2 in vitro Likewise, we analyzed the plasma levels of glucose, serine, arginine, lysine, taurine, and glutamic acid. RESULTS We observed significant differences in the glycine levels between PTB and PTB-DM2 vs C-DM2 and H-C groups (P  less then  0.05). We observed also important differences in insulin and glucose levels after comparisons between PTB, PTB-DM2, and C-DM2 vs. H-C groups (P  less then  0.05). A correlation between glycine and insulin levels in the PTB (r = 0.326) and PTB-DM2 (r = 0.318) groups was found. CONCLUSION Our results showed a significant association between glycine and insulin plasma levels in patients with PTB and PTB-DM2, which suggests that the determination of glycine levels could be used as a reference test to evaluate both pathologic conditions. An additional support to the above is that significant changes in the glucose levels in these groups were observed, too. Aggressive individuals more readily interpret others' motives and intentions in ambiguous situations as hostile. This hostile attribution bias has been argued to be causally involved in the development and maintenance of aggression, making it a target for interventions. In our current study, adolescents selected for high levels of aggression (N = 39) were assigned to either a test-retest control group or a five-session hostile attribution bias modification training, in which they were trained to make more benign interpretations of ambiguously provocative social situations. Before and after the training, we assessed hostile attribution bias and both reactive and proactive self-reported aggression in both groups. The training not only tended to produce the expected reduction in hostile attribution bias but also crucially led to decreased levels of reactive but not proactive aggression compared with the control group. Our results thus support the idea that hostile attribution bias can be targeted using training techniques and that such training-induced changes in bias may reduce aggression. However, future studies using an active control group and multiple outcome measures are needed to address the long-term effects of training. AIMS To evaluate the safety and efficacy of liver stereotactic body radiotherapy (SBRT) in the treatment of unresectable hepatocellular carcinomas (HCC) measuring >5 cm. MATERIALS AND METHODS Between November 2013 and February 2016, 13 patients with unresectable HCC (>5 cm), ineligible for other local treatments, with a Child-Pugh score (CPS) ≤ B7, were enrolled into a single-institution phase II study. SBRT was delivered by volumetric-modulated arc radiotherapy. Radiological response was reported using modified Response Evaluation Criteria in Solid Tumours criteria and toxicities graded by Common Terminology Criteria for Adverse Events v4 criteria. RESULTS Sixteen hepatomas (median size 7.5 cm, range 5.1-9.7 cm) were treated in 13 patients. The baseline CPS was A5/6 in nine patients (69%) and B7 in four patients (31%). Five patients (38%) received previous liver-directed treatment. The median prescribed dose was 45 Gy (range 40-45 Gy) in five fractions. The median follow-up was 17.7 months. The 1-year local control rate was 92%. The median overall survival was 17.7 months and the 1-year overall survival was 62%. The median time to local progression was not reached. Five patients (39%) had an increase in CPS by two or more points at 3 months. Overall, there were 10 grade 3 acute toxicities occurring in seven patients, of which six were haematological. Quality of life remained clinically stable or improved at 3 months in 61.5% and 53.8% of patients based on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 Global Health Score and Functional Assessment of Cancer Therapy - Hepatobiliary version 4 score, respectively. CONCLUSIONS In our cohort, SBRT to unresectable large HCC tumours provided excellent local control with acceptable toxicities. Regional recurrence remained the major cause of failure. Further studies are warranted to examine the role for SBRT in combination with other modalities to maximise disease control in the liver. PURPOSE Previous studies have reported controversial results regarding the risk of restenosis with polymorphisms of endothelial nitric oxide synthase (eNOS), matrix metalloproteinase 3 (MMP-3), angiotensinogen (AGT), and angiotensin II type 1 receptor (AT1R) after percutaneous coronary intervention (PCI). This study aimed to summarize the association between these polymorphisms and risk of restenosis after PCI. METHODS We searched the electronic databases of PubMed, Embase, Cochrane's Library, and ClinicalTrials.gov for studies on the association of eNOS, MMP-3, AGT, and AT1R polymorphisms with restenosis. FINDINGS A total of 17 studies (7781 patients) were analyzed, including 5 studies on eNOS G298A (n = 912), 5 studies on MMP3 5A/6A (n = 4519), 6 studies on AGT M235T (n = 1801), and 7 studies on AT1R A1166C (n = 2477). For the G298A variant of the eNOS gene, the allele odds ratio (OR) was 1.685 (95% CI, 1.269-2.338; P  less then  0.001), the heterozygote OR was 2.144 (95% CI, 1.490-3.085; P  less then  0.00 risk of restenosis after PCI. INTRODUCTION Frailty is associated with greater postoperative morbidity and mortality. Individualized multidisciplinary management of these patients can improve the quality of care. The objectives of this study are to determine the percentage of frail patients with colorectal cancer in our population, and to describe the morbidity and mortality associated with surgery and the evolution of palliative treatment. link2 METHODS A prospective, observational study of patients with surgical colorectal cancer (February 1, 2018-April 30, 2019). Frail patients were screened and classified according to degrees of frailty. Therapeutic decision-making (surgery or palliative treatment) was determined by the degree of fragility and explicit will of the patient. Postoperative comorbidities were analyzed (according to Clavien-Dindo and Comprehensive Complication Index), as were mortality and oncological follow-up. RESULTS The study included 193 patients with surgical colorectal cancer, with a mean age of 74 years (44-92). Screening identified 46 frail patients (24%), with a mean age of 80 years (57-92). Twenty-two patients were optimized and underwent surgery (48%), with a mean age of 78 years (57-89). Relevant adverse effect rate was 27.7% (4 grade iva adverse effects, one ivb and one v, according to Clavien-Dindo). Comprehensive Complication Index was 17.5. Palliative treatment was administered in 24 patients (52%), with a mean age of 82 years (59-92). Mean follow-up was 7.8 months. There were 2 deaths due to disease progression (8.3%), 5 re-consultations due to complications of colorectal cancer (20.1%). CONCLUSIONS The multidisciplinary and individualized management of frail patients with colorectal cancer is key to improve the quality of care in the treatment of this patient group. BACKGROUND This paper explores a method for assessing intraoperative performance by modeling how surgeons integrate skills and knowledge through discourse. METHODS Senior residents (N = 11) were recorded while performing a simulated laparoscopic ventral hernia (LVH) repair. link3 Audio transcripts were coded for five discourse elements related to knowledge, skills, and operative independence. Epistemic network analysis was used to model the ordered integration of the five discourse elements. RESULTS Participants with poorer hernia repair outcomes had stronger connections between the discourse elements operative planning and asking for information or advice (Operative planning), while participants with better hernia repair outcomes had stronger connections between the discourse elements giving assistant instructions and identifying errors (Operative management) (p = .006; Cohen's d = 2.79). CONCLUSION Participants with better hernia repair outcomes engaged in more operative management communication during the simulated procedure.
