Abstract
The DNA helicase FANCJ is mutated in hereditary breast and ovarian cancer and Fanconi anemia (FA). Nevertheless, how loss of FANCJ translates to disease pathogenesis remains unclear. We addressed this question by analyzing proteins associated with replication forks in cells with or without FANCJ. We demonstrate that FANCJ-knockout (FANCJ-KO) cells have alterations in the replisome that are consistent with enhanced replication stress, including an aberrant accumulation of the fork remodeling factor helicase-like transcription factor (HLTF). Correspondingly, HLTF contributes to fork degradation in FANCJ-KO cells. Unexpectedly, the unrestrained DNA synthesis that characterizes HLTF-deficient cells is FANCJ dependent and correlates with S1 nuclease sensitivity and fork degradation. These results suggest that FANCJ and HLTF promote replication fork integrity, in part by counteracting each other to keep fork remodeling and elongation in check. Indicating one protein compensates for loss of the other, loss of both HLTF and FANCJ causes a more severe replication stress response.

Abstract
BACKGROUND Rheumatoid arthritis (RA) patients are at increased risk of insulin resistance (IR); however, the specific mechanisms mediating this association are currently unknown. OBJECTIVE To investigate whether the inflammatory activity associated with RA accounts for the observed defective glucose metabolism and lipid metabolism in these patients. METHODS We followed two main strategies: (i) extensive metabolic profiling of a RA cohort of 100 patients and 50 healthy control subjects and (ii) mechanistic studies carried out in both a collagen-induced arthritis mouse model and 3T3-L1 adipocytes treated with conditioned serum from RA patients. RESULTS Following the exclusion of obese and diabetic subjects, data from RA patients demonstrated a strong link between the degree of systemic inflammation and the development of IR. These results were strengthened by the observation that induction of arthritis in mice resulted in a global inflammatory state characterized by defective carbohydrate and lipid metabolism in different tissues. Adipose tissue was most susceptible to the RA-induced metabolic alterations. These metabolic effects were confirmed in adipocytes treated with serum from RA patients. CONCLUSIONS Our results show that the metabolic disturbances associated with RA depend on the degree of inflammation and identify inflammation of adipose tissue as the initial target leading to IR and the associated molecular disorders of carbohydrate and lipid homeostasis. Thus, we anticipate that therapeutic strategies based on tighter control of inflammation and flares could provide promising approaches to normalize and/or prevent metabolic alterations associated with RA.

Abstract
BACKGROUND The prevalence of obesity has increased dramatically, even in the population awaiting a liver transplantation. Despite their associated complications, we cannot consider morbid obesity any longer as an absolute contraindication to liver transplantation. Dietary approaches alone are usually completely ineffective. Bariatric surgery is the gold-standard treatment for morbid obesity and can be performed before, during, or after transplantation. MATERIALS AND METHODS At our Liver Transplantation Unit, a single surgeon performed a sleeve gastrectomy in 8 patients with liver cirrhosis due to nonalcoholic steatohepatitis, alcohol, or HCV. The Child score was A in 6 patients and B in the remaining 2 patients. Two of our patients had portal hypertension with mild esophageal varices. The procedure was performed laparoscopically in 7 cases (87.5%); in the other case, it was performed by open approach due to portal hypertension and according to patient preferences. RESULTS Patients showed no postoperative morbidity or mortality. The mean postoperative body mass index of our patients was 37.4, 33.3, and 30.3 kg/m2 at 3, 6, and 12 months after surgery, respectively. The mean percentage excess weight loss of our patients was 42.9%, 62.2%, and 76.3% at 3, 6, and 12 months. Two of the patients have already undergone a successful liver transplant. CONCLUSION Bariatric surgery in selected patients with compensated cirrhosis and without significative portal hypertension is reasonable. There are not clear guidelines on the use of bariatric surgery in patients with cirrhosis. In our experience, the sleeve gastrectomy is safe and effective in the treatment of patients with compensated cirrhosis; in a short time, the sleeve gastrectomy can improve candidacy in morbidly obese patients awaiting transplantation.

Abstract
In the period from July 2008 to 2010, a disease episode resulting in serious economic losses in the major production area of the Chilean poultry industry was reported. These losses were associated with respiratory problems, increase of condemnations, drops in egg production and nephritis in breeders, laying hens and broilers due to infections with infectious bronchitis virus (IBV). Twenty-five IBV isolates were genotyped and four strains were selected for further testing by pathotyping and protectotyping. Twenty-four IBV isolates were of the Q1 genotype. The experiments also included comparing the ability of six vaccination programmes to induce virus neutralizing antibodies (VNA) in layers against four selected Chilean strains. Despite the high genetic homology in the S1 gene between the four strains, the heterogeneity in biological behaviour of these different Q1 strains was substantial. These differences were seen in embryonated eggs, in cell culture, in pathogenicity and in level of cross-protection by IBV Massachusetts (Mass) vaccination. This variability underlines the importance of testing more than one strain per serotype or genotype to determine the characteristics of a certain serotype of genotype. The combination of Mass and 793B vaccine provided a high level of protection to the respiratory tract and the kidney for each strain tested in the young birds. The combination of broad live priming using Mass and 793B vaccines and boosting with multiple inactivated IBV antigens induced the highest level of VNA against Q1 strains, which might be indicative for higher levels of protection against Q1 challenge in laying birds.

Abstract
Intestinal failure (IF) is a debilitating condition of inadequate nutrition due to an anatomical and/or physiological deficit of the intestine. Surgical management of patients with acute and chronic IF requires expertise to deal with technical challenges and make correct decisions. Dedicated IF units have expertise in patient selection, operative risk assessment and multidisciplinary support such as nutritional input and interventional radiology, which dramatically improve the morbidity and mortality of this complex condition and can beneficially affect the continuing dependence on parenteral nutritional support. Currently there is little guidance to bridge the gap between general surgeons and specialist IF surgeons. Fifteen European experts took part in a consensus process to develop guidance to support surgeons in the management of patients with IF. Based on a systematic literature review, statements were prepared for a modified Delphi process. The evidence for each statement was graded using Oxford Centre for Evidence-Based Medicine Levels of Evidence. The current paper contains the statements reflecting the position and practice of leading European experts in IF encompassing the general definition of IF surgery and organization of an IF unit, strategies to prevent IF, management of acute IF, management of wound, fistula and stoma, rehabilitation, intestinal and abdominal reconstruction, criteria for referral to a specialist unit and intestinal transplantation.

Abstract
OBJECTIVE At present there is a controversy regarding the impact of positive bile cultures on morbidity and mortality rates, and on the incidence of readmissions in patients with biliar disease. The aim of this study was to evaluate the role of bacteriobilia in postoperatory infections, mortality or readmissions in these patients. METHODS The information was obtained from all patients with bile cultures admitted to Hospital Universitario Marqués de Valdecilla (Santander, Spain) from January to December 2011. Clinical, epidemiological and microbiological data and laboratory findings were analyzed. The patients were followed for two years. RESULTS One hundred and fifty-two patients (65% men) were included. Mean age was 67 years (SD= 15 years). The most frequent diagnoses were acute cholecystitis (79%) and cholangitis (8%). Laparoscopic cholecystectomy was performed in 42% of patients, open cholecystectomy in 45% and percutaneous cholecystostomy in 8%. Bacteriobilia was present in 83 patients (55%). The most frecuent microorganisms isolated were Escherichia coli (31%), Enterococcus faecium (13%) and Klebsiella pneumoniae (13%). The initial antimicrobial agent was a carbapenem in 62 patients (44%) and piperacillin-tazobactam in 28 (18%). There were 39 postoperative infections (26%), 21 readmissions (14%) and 17 patients died during admission (11%). The presence of microorganisms in bile cultures was not a statistically significant predictor of neither complications nor readmissions. CONCLUSIONS Intra-operative bile cultures would allow guide early appropriate antibiotic treatment use in case of infection, or empiric antimicrobial therapy, however there was no correlation between bacteriobilia and postoperative infections, length of stay, mortality or readmissions.

Abstract
Advances on cryopreservation techniques now allow considering oocyte, embryo or ovarian tissue freezing for female fertility preservation. Originally developed for patients suffering from cancer, fertility preservation has rapidly invaded others medical fields, and represents now the standard of care for all young patient diagnosed with a disease that could impair fertility or having to receive possibly gonadotoxic treatment. As a result, autoimmune diseases, some genetic pathologies or iterative pelvic surgeries, at risk of premature ovarian failure, have become common indications of fertility preservation. In addition, the social egg freezing aiming at preventing the age-related fertility decline is still debated in France, although authorized in numerous countries. This review will discuss the different strategies of fertility preservation in young girls and women of reproductive age, regarding different medical or non-medical indications.

Abstract
OBJECTIVE To describe the clinical characteristics and evolution of our series of medication-related osteonecrosis of the jaws (MRONJ) associated with denosumab in osteoporotic patients. MATERIAL AND METHODS We present 10 new cases of MRONJ in patients receiving denosumab for osteoporosis. We describe the mean doses of denosumab, previous bisphosphonate intake, and the clinical characteristics associated with the osteonecrosis, such as local contributing factors, symptoms, and evolution after treatment. RESULTS The mean number of denosumab doses was 3.4 ± 2.2. In 90% of patients, there was a prior history of oral bisphosphonate intake, with a mean duration of 46.78 ± 25.11 months. The most common local factor was dental extraction (6 cases; 60%), and most cases had necrotic bone exposure (9/10, 90%). Sclerosis of the bone was the most common radiographic finding. Stage 1 was the most common ONM stage, found in 80%. 'Cure' after conservative treatments was obtained in 71.4%. CONCLUSIONS Most of our cases were in the early stages of MRONJ, and the success rate after conservative treatment was high.

Abstract
BACKGROUND AND AIMS Combination of hepatitis B immunoglobulin (HBIG) and a nucleos(t)ide analog (NA) is considered the standard of care for prophylaxis of hepatitis B virus (HBV) recurrence after liver transplantation (LT). However, use of lifelong HBIG has significant limitations. We evaluated the efficacy and safety of entecavir (ETV) or tenofovir disoproxil fumarate (TDF) after withdrawal of HBIG in patients who had been under HBIG-regimen prophylaxis post LT. METHODS Patients at low risk of recurrence were eligible for HBIG discontinuation (fulminant HBV hepatitis, co-infection with hepatitis D virus, and hepatitis B e antigen-negative cirrhotic patients with HBV DNA levels <300 copies/mL). All patients had received HBIG, with or without NA, for at least 12 months after LT. After HBIG discontinuation, they continued with ETV or TDF monotherapy. Patients were followed up with HBV serum markers and evaluation of renal function. RESULTS Between September 2011 and June 2014, 58 liver transplant recipients were converted to TDF (31, 53%) or ETV (27, 47%). Mean follow-up after conversion was 28 ± 5 months (range 13-36 months). Five patients (8.6%) developed detectable hepatitis B surface antigen at 7, 9, 13, 15, and 22 months after HBIG discontinuation. However, in every case seroconversion was transitory, serum HBV DNA was undetectable, with no clinical manifestations of HBV recurrence. No adverse effects were observed or dose reductions required associated with ETV or TDF. CONCLUSIONS Maintenance therapy with newer NAs, after discontinuation of HBIG prophylaxis, was safe and effective, with a low rate of serological recurrence and no evident clinical, biochemical, or virological consequences.
