BACKGROUND Crohn’s disease(CD)is complicated by perianal fistulas in approximately 20%of patients.Achieving permanent fistula closure remains a challenge for physicians.An association between serum anti-tumor necrosis factor-αconcentrations and clinical outcomes in patients with CD has been demonstrated;however,little information is available on serum adalimumab(ADA)concentrations and remission of perianal fistulas in such patients.AIM To study the relationship between serum ADA concentrations and clinical remission of CDassociated perianal fistulas.METHODS This cross-sectional study of patients with CD-associated perianal fistulas treated with ADA was performed at four French hospitals between December 2013 and March 2018.At the time of each serum ADA concentration measurement,we collected information about the patients and their fistulas.The primary study endpoint was clinical remission of fistulas defined as the absence of drainage(in accordance with Present’s criteria),with a PDAI≤4,absence of a seton and assessment of the overall evaluation as favorable by the proctologist at the relevant center.We also assessed fistula healing[defined as being in clinical and radiological(magnetic resonance imaging,MRI)remission]and adverse events.RESULTS The study cohort comprised 34 patients who underwent 56 evaluations(patients had between one and four evaluations).Fifteen patients had clinical remissions(44%),four of whom had healed fistulas on MRI.Serum ADA concentrations were significantly higher at evaluations in which clinical remission was identified than at evaluations in which it was not[14(10-16)vs 10(2-15)μg/mL,P=0.01].Serum ADA concentrations were comparable at the times of evaluation of patients with and without healed fistulas[11(7-14)vs 10(4-16)μg/mL,P=0.69].The adverse event rate did not differ between different serum ADA concentrations.CONCLUSION We found a significant association between high serum ADA concentrations and clinical remission of CD-associated perianal fistulas.

Cultivated for its richness in nutrients, tomato culture is demanding fertilizer, especially in calcium. Calcium deficiencies and physiological disorders cause serious diseases in tomatoes. Blossom end rot (BER), in susceptible cultivars, may cause severe economic losses. The goal of this study is to determine the effect of three organic calcium sources on the growth and quality of fruit production of tomatoes. Egg, snail and sea shell powders and extracts have been used as biological fertilizers. The experiment was conducted in a block factorial trial with three replications. The trials comprised two factors: calcium sources and calcium source form (powder and extract). The results showed that the growth parameters and yield were improved by the calcium source, whatever the form. Also, BER was lower in plants treated with calcium contrary to the control. However, plants treated with eggshells showed the best growth (mean) and the lowest rate (0.40%) of BER than the snail and sea shell.

Flow around a cavity is characterized by a self-sustained mechanism in which the shear layer impinges on the downstream edge of the cavity resulting in a feedback mechanism.Direct Numerical Simulations of the flow at low Reynolds number has been carried out to get pressure and velocity fluctuations,for the case of un-actuated and multi frequency actuation.A Reduced Order Model for the isentropic compressible equations based on the method of Proper Orthogonal Decomposition has been constructed.The model has been extended to include the effect of control.The Reduced Order dynamical system shows a divergence in time integration.A method of calibration based on the minimization of a linear functional of error,to the sensitivity of the modes,is proposed.The calibrated low order model is used to design a feedback control of cavity flows based on an observer design.For the experimental implementation of the controller,a state estimate based on the observed pressure measurements is obtained through a linear stochastic estimation.Finally the obtained control is introduced into the Direct Numerical Simulation to obtain a decrease in spectra of the cavity acoustic mode.

Garcinia kola Heckel, called “petit cola” in Côte d’Ivoire and “bitter kola” in Nigeria, is a Non-Timber Forest Product of great socioeconomic importance. Unfortunately, this species is threatened due to overexploitation and deforestation. This study tested the effect of leaf area on stem cuttings to regenerate vegetatively in a non-mist poly-propagator without using exogenous hormones. Three stem cuttings types: greenwood, softwood and hardwood (12 - 15 cm in length) were collected from 24-month years old seedlings. The two top leaves of each cutting type were conserved at different leaf area: 0 cm2, 28.25 cm2, 56.5 cm2, 84.75 cm2 and 113 cm2 (entire leaf area). Observations were made on rooting, sprouting and leafing abilities of cuttings depending to treatments applied. Results showed that all cutting types have presented good ability to shooting and rooting. Cuttings with 113 cm2 leaf areas presented the best rooting (94.44% ± 2.42%) and shouting (95.55% ± 2.42%) percentage and longest primary root length (12.03 ± 0.50 cm). Hardwood, softwood and greenwood cuttings with 113 cm2 leaf area had the best rooting percentage (96.66% ± 3.33%, 96.66% ± 5.77% and 90.00% ± 5.77% respectively). The longest primary root length (13.50 ± 0.97 cm) was observed to greenwood cuttings with 113 cm2 leaf area. Regenerated plants in the forest presented well survival percentage (96.66%). This study shows that it is possible to regenerate entire plants by cuttings without using external hormones in non-mist poly-propagator.

AIM To describe factors associated with treatment failure and frequency of resistance-associated substitutions(RAS).METHODS Human immunodeficiency virus(HIV)/hepatitis C virus(HCV) coinfected patients starting a first direct-acting antiviral(DAA) regimen before February 2016 and included in the French ANRS CO13 HEPAVIH cohort were eligible. Failure was defined as:(1) non-response [HCV-RNA remained detectable during treatment, at end of treatment(EOT)]; and(2) relapse(HCVRNA suppressed at EOT but detectable thereafter). Sequencing analysis was performed to describe prevalence of drug class-specific RAS. Factors associated with failure were determined using logistic regression models.RESULTS Among 559 patients, 77% had suppressed plasma HIV-RNA < 50 copies/mL at DAA treatment initiation, 41% were cirrhotic, and 68% were HCV treatmentexperienced. Virological treatment failures occurred in 22 patients and were mainly relapses(17, 77%) then undefined failures(3, 14%) and non-responses(2, 9%). Mean treatment duration was 16 wk overall. Posttreatment NS3, NS5 A or NS5 B RAS were detected in 10/14 patients with samples available for sequencing analysis. After adjustment for age, sex, ribavirin use, HCV genotype and treatment duration, low platelet count was the only factor significantly associated with a higher risk of failure(OR: 6.5; 95%CI: 1.8-22.6). CONCLUSION Only 3.9% HIV-HCV coinfected patients failed DAA regimens and RAS were found in 70% of those failing. Low platelet count was independently associated with virological failure.

Mirizzi syndrome, a rare complication of gallstones, is defined by obstruction of the main bile duct. This obstruction may worsen and thus result in cholecystobiliary fistula. Surgical management of Mirizzi syndrome is complicated by the presence of inflamed tissue around the hepatic pedicle, making it impossible to distinguish between the main bile duct and the gallbladder. The surgeon＇s first task is to perform subtotal cholecystotomy（from the fundus of the gallbladder to the neck） without trying to locate the cystic duct. In a second step, the gallstones are extracted and the main bile duct is then repaired. In most cases, a T-tube is used to drain the main bile duct, and abdominal drainage is left in place（in case a bile fistula forms）. This study concluded that preoperative drainage of the main bile duct in the treatment of Mirizzi syndrome types II and III is feasible and might help to decrease the postoperative complication rate.
