Laparoscopic ventral hernia repair with intraperitoneal onlay mesh reinforcement is often performed in clinical practice. We herein describe a patient who developed a Spigelian hernia at the edge of the mesh due to rupture of the muscular layer in the abdominal wall. A 69-year-old woman developed a left-sided abdominal bulge 15 months after laparoscopic ventral hernia repair. CT showed a 33-mm defect in the abdominal wall at the lateral edge of the left abdominal rectus muscle with an intestinal prolapse through the defect. She was diagnosed with a Spigelian hernia and underwent operation. The hernia orifice was located at the aponeurosis of the transverse abdominal muscle where the thread had been used to fix the mesh through all layers of the abdominal wall. This report details a case of a Spigelian hernia after laparoscopic ventral hernia repair.
Differentiation of benign and malignant pancreatic cystic lesions on MRI, computed tomography (CT), and endoscopic ultrasound (EUS) is critical for determining management.

To perform a systematic review evaluating the diagnostic accuracy of MRI for diagnosing malignant pancreatic cystic lesions, and to compare the accuracy of MRI to CT and EUS.

Systematic review and meta-analysis.

MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus were searched until February 2020 for studies reporting MRI accuracy for assessing pancreatic cystic lesions.

1.5T or 3.0T.

Methodologic and outcome data were extracted by two reviewers (AU and MA, 2 years of experience each). All studies of pancreatic cystic lesions on MRI were identified. Studies with incomplete MRI technique were excluded. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool.

Sensitivity/specificity was pooled using bivariate random-effects meta-analysis with 9ICAL EFFICACY STAGE 2.

We present our initial experience with the fourth-generation MitraClip™ (G4) system and propose preliminary criteria for device selection.

The MitraClip™ G4 system recently underwent a "controlled release" for transcatheter edge-to-edge mitral valve repair. The four new devices include technical improvements such as controlled gripper actuation (independent leaflet capture) and continuous left atrial pressure monitoring. To date, a patient-specific device selection algorithm, and the technology's impact on procedural times and success, have not been described.

We present an initial multi-center experience and short-term outcomes with the new system, suggest procedural and imaging considerations, and propose initial guidance for device selection.

Sixty-one procedures performed by three operators at two centers between November 2019 and May 2020 were analyzed. At 30-day follow-up, there were three deaths (4.9%), four neurological events (6.6%), and seven re-hospitalizations (11.5%). Fifty-nine patients experience should provide a foundational opportunity for further refinement.Monofluorinated alkyl compounds are of great importance in pharmaceuticals, agrochemicals and materials. Herein, we describe a direct nickel-catalyzed monofluoromethylation of unactivated alkyl halides using a low-cost industrial raw material, bromofluoromethane, by demonstrating a general and efficient reductive cross-coupling of two alkyl halides. Results with 1-bromo-1-fluoroalkane also demonstrate the viability of monofluoroalkylation, which further established the first example of reductive C(sp3 )-C(sp3 ) cross-coupling fluoroalkylation. These transformations demonstrate high efficiency, mild conditions, and excellent functional-group compatibility, especially for a range of pharmaceuticals and biologically active compounds. Mechanistic studies support a radical pathway. Kinetic studies reveal that the reaction is first-order dependent on catalyst and alkyl bromide whereas the generation of monofluoroalkyl radical is not involved in the rate-determining step. This strategy provides a general and efficient method for the synthesis of aliphatic fluorides.
To assess different techniques to measure body composition in paediatric patients with inflammatory bowel disease using dual energy X-ray absorptiometry as a reference method. We hypothesised that a three-compartment model may demonstrate superiority over other methods as skinfold thickness equations and bioelectrical impedance analysis.

Body composition was assessed using skinfold thickness equations, bioelectrical impedance analysis and the three-compartment model. Data obtained with these methods were compared to the results obtained by dual energy X-ray absorptiometry. Selleck MSU-42011 Statistical analysis was performed using Spearman's correlation and Bland-Altman's limits of agreement method.

Twenty-one paediatric patients with inflammatory bowel disease were included 11 females and 10 males; mean age for the entire group 14.3 years, range 12-16 years. In children with inflammatory bowel disease, skinfold thickness equations, bioelectrical impedance analysis and the three-compartment model showed reliable measurements with small differences in the percentage of total body fat and good limits of agreements.

The assessment of body composition using bioelectrical impedance analysis provides a valid and accurate method in children with inflammatory bowel disease as compared to dual energy X-ray absorptiometry. In the future, superiority of 3-compartment model in research and clinical settings of nutritional intervention and disease status in children with inflammatory bowel disease remains to be demonstrated.

The aim of the present study was to assess the feasibility and reliability of transperineal ultrasound in the assessment of breech descent in the birth canal, by measuring the "breech progression angle".

We recruited pregnant women with singleton pregnancies and fetuses in breech presentation between 34 and 41 weeks' gestation. We acquired transperineal ultrasound images in the midsagittal view for each woman twice by an operator and once by another. Each operator measured the breech progression angle after anonymization of the transperineal ultrasound images. Breech progression angle was defined as the angle between a line running along the long axis of the pubic symphysis and another line extending from the most inferior portion of the symphysis tangentially to the lowest recognizable fetal part in the maternal pelvis. Each operator was blinded from any other measurement performed for the same woman. The intra- and interobserver reproducibility were evaluated with intraclass correlation coefficient (ICC).
