011) did not uphold when correcting for NS in the model. In turn, a significant negative association between NS and OFC GMV was found independent of BMI (x = -2, y = 48, z = -10, t(349) = 4.42, k = 88, pFWE = 0.008). Body mass-related grey matter decrease outside the OFC could not be attributed to NS. Our results suggest that body-weight-related orbitofrontal grey matter reduction can at least partly be linked to higher levels of NS. Given the pivotal role of the OFC in overweight as well as cognitive domains such as impulse inhibition, executive control and reward processing, its association with NS seems to provide a tenable neurobiological correlate for future research.Ectopic pregnancy is a frequent and life-threatening risk of childbearing. Its management represents a mainstay of emergency gynecological surgery, and laparoscopy is the surgical gold standard technique. The technique of transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) for the management of ectopic pregnancy is presented herein. The procedure is illustrated by an instructive video article that standardizes the essential steps to make the technique ergonomic and easy to perform (step-by-step explanations). This surgical technique allows to consider vaginal salpingectomy using a combined cœlio-vaginal approach. After a posterior colpotomy, an Alexis retractor was inserted in the pouch of Douglas followed by the placement of a dedicated platform on which three trocars were fixed. Pneumoperitoneum was then achieved. Once the diagnosis of ruptured tubal ectopic pregnancy was established, a salpingectomy was performed. As a minimally invasive approach, this procedure has high patient acceptance and seems to improve favorable clinical outcomes.Success in global surgery interventions cannot be claimed until consistent long-term follow up is achieved and corresponding outcomes are studied. However, post-operative outcomes remain inconsistently collected and analyzed in the setting of global surgery, with current efforts largely focused on the delivery of surgical care. Barriers in low- and middle-income countries include patient cost and distance, low surgical workforce capacity, poor patient health literacy, lack of affordable technology availability, inconsistent documentation, and structural deficiencies. Here, we suggest that future work can be focused on (1) enhancing systems to facilitate long-term follow up and care, (2) expanding availability and adoption of electronic medical record systems, and (3) collaboration with local surgeons in the development of international cross-organizational registries and standardized quality measures. Long-term collaborations between local healthcare administrators and providers, policymakers, international bodies, nonprofit organizations, patients, and the private sector are necessary to build and sustain processes to achieve reliable long-term follow up and rigorous data collection, with the goal of ultimately ensuring better patient outcomes.

Decreased blood coagulation factor (F)XIa levels have been shown to protect from thrombosis without bleeding side effects, but less is known on effects of increased FXIa levels. Studies are hampered by lack of a reliable and robust method for FXIa quantification in blood. We aim to develop a new assay employing a unique multivalent catch-and-release system. The system selectively isolates and protects homodimeric FXIa from plasma and releases free FXIa allowing subsequent quantification.

A dynamic multivalent construct was synthesized by complexing four identical FXIa inhibitors from the snake Bungarus Fasxiatus to avidin through desthiobiotin-PEG-linkers, allowing dissociation of FXIa by excess biotin. PEG-linker lengths were optimised for FXIa inhibitory activity and analysed by Michaelis-Menten kinetics. Finally, the catch-and-release assay was validated in buffer and plasma model systems.

Monovalent and multivalent inhibitor constructs were successfully obtained by total chemical synthesis. Multimerisation of Fasxiator resulted in a 30-fold increase in affinity for FXIa from 1.6nM to 0.05nM. With use of this system, FXIa could be quantified down to a concentration of 7 pM in buffer and 20 pM in plasma.

In this proof-of-concept study, we have shown that the catch-and-release approach is a promising technique to quantify FXIa in plasma or buffer. By binding FXIa to the multivalent construct directly after blood drawing, FXIa is hypothesized to be inaccessible for serpin inhibition or auto inactivation. This results in a close reflection of actual circulating FXIa levels at the moment of blood drawing.

The influences of solution pH, contact time, initial concentration, and competing cations were examined and discussed. Stable cobalt uptake was observed at pH 4-8. The sorption kinetics showed a multi-stage uptake profile, implying that several mechanisms are involved in the adsorption process. Microscopy and structural analysis revealed that DCPD decomposes to its anhydrous form during adsorption, which explains the multistep curve over the entire adsorption period. However, the non-apatitic transformation is not exclusive to cobalt uptake. Intraparticle diffusion also contributed to the overall removal kinetics of Co2+ from water. Considering the Sips isotherm model, the maximum Co2+ adsorption capacity of DCPD was 441 mg g-1. Cobalt uptake selectivity dropped in the presence of Ca2+ ions, from 1.21 × 104 to 207 mL g-1, indicating DCPD would be more applicable in treating soft 60Co-contaminated waters. Structural analysis, elemental mapping, and qualitative analysis of solid residues confirmed that ion exchange is involved in the removal of cobalt from aqueous solutions.
