6]%), this declined (CE-N 89 [73.4-98.2]%; CE-IM 77.8 [65.6-88]%) over 3.4years of follow-up. There was considerable heterogeneity. Only two studies reported a post-BET follow-up of >5years (CE-IM 50 [41.5%-58.5]%). Higher person years of follow-up seem to correlate with decrease in BET efficacy.

Using stringent criteria for appropriate study selection with sufficient follow-up, a lack of high-quality controlled intervention trials becomes evident for assessment of long-term durable remission rates of BET despite initial high success rates. We plea for a uniform documentation of study details which could be used in future trials.

Pulmonary disease may be the presenting sign and the few patients reported so far, all deceased in early infancy. learn more Exome sequencing was performed on patients with childhood interstitial lung disease (chILD) and additional neurological features. The chILD-EU register database and an in-house database were searched for patients with NHLRC2 variants and clinical features overlapping FINCA syndrome. Six patients from three families were identified with bi-allelic variants in NHLRC2. Two of these children died before the age of two while four others survived until childhood. Interstitial lung disease was pronounced in almost all patients during infancy and stabilized over the course of the disease with neurodevelopmental delay (NDD) evolving as the key clinical finding. We expand the phenotype of FINCA syndrome to a multisystem disorder with variable severity. FINCA syndrome should also be considered in patients beyond infancy with NDD and a history of distinct interstitial lung disease. Managing patients in registers for rare diseases helps identifying new diagnostic entities and advancing care for these patients.

We reported on the superiority of preoperative Duplex mapping ("Duplex") over audible Dopplers ("Doppler") in anterolateral thigh perforator (ALT) free flaps for upper extremity reconstruction. To corroborate our findings on a larger cohort, we conducted this present study focusing on surgical efficiency and patient safety.

150 consecutive ALT free flaps were divided into 65 cases of preoperative Duplex versus 85 Doppler controls. We first compared patient demographics, operative details, and defect and flap characteristics. We then assessed group differences in the number and course of perforators pursued intraoperatively, flap harvest and operative times, and donor-site complications. Additionally, the impact of the training level of the primary microsurgeon was evaluated.

Cases and controls were comparable regarding age (p= .48), sex (p= .81), ASA class (p= .48), and BMI (p= .90). Duplex was associated with an increased likelihood of raising flaps on one single dominant perforator of purely septal course and significant reductions of flap harvest (68 ± 10min, p< .0001) and operative times (74 ± 16 min, p< .0001), regardless of the experience of the primary microsurgeon. There were strong negative linear correlations between preoperative Duplex and both the flap harvest and operative times (p< .0001). Additionally, while there was no effect on the emergency take-back rate (OR=1.3, p= .60), revisions were significantly less likely among duplexed patients (OR=0.15, p= .04).

Preoperative Duplex is associated with a significant reduction in ALT free flap harvest and overall operative times, as well as donor-site revisions as opposed to Doppler planning, regardless of the training level of the primary microsurgeon.

Obesity may affect efficacy and safety of biologic treatments for ulcerative colitis (UC). Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of UC.

To assess efficacy and safety of tofacitinib in patients with UC, by baseline body mass index (BMI).

This post hoc analysis evaluated patients with UC receiving placebo or tofacitinib from the 8-week OCTAVE Induction 1 and 2 (NCT01465763, NCT01458951) and 52-week OCTAVE Sustain (NCT01458574) studies. Patients were stratified by BMI at OCTAVE Induction 1 and 2 baseline (<25, 25 to <30 and ≥30kg/m

). Outcomes included remission, endoscopic improvement, clinical response, sustained steroid-free remission, Inflammatory Bowel Disease Questionnaire total score and Short Form-36 Health Survey scores. Adverse events were evaluated.

At Week 8 of OCTAVE Induction 1 and 2, and Week 52 of OCTAVE Sustain, higher proportions of patients receiving tofacitinib 5 or 10mg twice daily (b.d.) achieved clinical response vs placebo, regardless of baseline BMI subgroup (all P<0.05). Proportions of patients achieving efficacy endpoints were generally similar across BMI subgroups; in univariate and multivariate regression analyses, BMI was not a significant predictor (all P≥0.05; univariate BMI [continuous] odds ratio for remission 0.98 [95% confidence interval 0.95, 1.02]). There was no consistent trend between BMI and adverse events. Among patients receiving tofacitinib 10mg b.d. in OCTAVE Induction 1 and 2, serious infections were numerically greater in the BMI ≥30 subgroup (3.2%) vs other subgroups (0.4%). Limitations included small patient numbers in the BMI ≥30 subgroup.

Efficacy and safety of tofacitinib were similar in patients with UC regardless of baseline BMI.

Portal hypertension is the main determinant of clinical decompensation in patients with liver cirrhosis. In preclinical data metformin lowers portal pressure, but there are no clinical data for this beneficial effect.

To investigate the acute effects of metformin on hepatic venous pressure gradient (HVPG) and liver perfusion.

In a randomised, double-blinded study design, we investigated 32 patients with cirrhosis before and 90minutes after ingestion of 1000-mg metformin (n=16) or placebo (n=16). Liver vein catherisation was performed to evaluate HVPG and indocyanine green (ICG) infusion for investigation of hepatic blood flow.

The mean relative change in HVPG was -16% (95% CI -28% to -4%) in the metformin group compared with 4% (95% CI -6% to 14%) in the placebo group (time×group interaction, P=0.008). In patients with baseline HVPG ≥12mm Hg clinically significant improvements in HVPG (HVPG <12mm Hg or a >20% reduction in HVPG) were observed in 46% (6/13) of metformin-treated and in 8% (1/13) of placebo-treated patients (P=0.07). There were no changes or differences in systemic blood pressure, heart rate, hepatic plasma and blood flow, hepatic ICG clearance, hepatic O

uptake or inflammation markers between groups.

A single oral metformin dose acutely reduces HVPG in patients with portal hypertension without affecting systemic or liver hemodynamics or inflammatory biomarkers. This offers a promising perspective of a safe and inexpensive treatment option that should be investigated in larger-scale clinical studies with long-term outcomes in patients with cirrhosis and portal hypertension.

This review summarizes progress in chiral polythiophenes (PThs) in the past 10 years, including the synthesis, properties and applications. Main focus is placed on the manner in which chirality is implemented and the optical activity of the chiral PThs. We showcase examples in which the chirality of PThs is induced by side chain substituents with point, planar, and axial chirality or arises from external chiral media. Application of chiral PThs is also included. Finally, perspectives for further development are offered.The freshwater crayfish is capable of regenerating limbs, following autotomy, injury and predation. In arthropod species, regeneration and moulting are two processes linked and strongly regulated by ecdysone. The regeneration of crayfish limbs is divided into wound healing, blastema formation, cellular reprogramming and tissue patterning. Limb blastema cells undergo proliferation, dedifferentiation and redifferentiation. A limb bud, containing folded segments of the regenerating limb, is encased within a cuticular sheath. The functional limb regenerates, in proecdysis, in two to three consecutive moults. Rapid tissue growth is regulated by hormones, limb nerves and local cells. The TGF-β/activin signalling pathway has been determined in the crayfish, P. fallax f. virginalis, and is suggested as a potential regulator of tissue regeneration. In this review article, we discuss current understanding of tissue regeneration in the crayfish and various crustaceans. A thorough understanding of the cellular, genetic and molecular pathways of these biological processes is promising for the development of therapeutic applications for a wide array of diseases in regenerative medicine.The aminoglycoside antibiotic neomycin, which is used to treat external or internal bacterial infections, is primarily administered in veterinary medicine as a sulfate salt. However, no information is available on the pharmacokinetic characteristics and absolute availability of neomycin sulfate after intravenous (i.v.) and oral (p.o.) administrations in swine. Here, these parameters were studied in swine after i.v. and p.o. doses of single 15 mg/kg body weight doses. The blood samples were assessed using ultra-high-performance liquid chromatography-tandem mass/mass spectrometry (UPLC-MS/MS) and pharmacokinetic parameters were analyzed using a non-compartmental model. In swine, after the p.o. administration, the elimination half-life, mean residue time from t0 to the last collection point, mean maximum concentration, mean time to reach maximum concentration and area under concentration-time curve from t0 to the last collection point values were 12.43 ± 7.63 h, 10.25 ± 4.32 h, 0.11 ± 0.07 μg/ml, 1.92 ± 0.97 h and 1.
