Laparoscopic distal gastrectomy is used widely in surgery for gastric cancer. Excess visceral fat can limit the ability to dissect the suprapancreatic region, potentially increasing the risk of local complications, particularly pancreatic fistula. This study evaluated perirenal fat thickness as a surrogate for visceral fat to see whether this was related to complications after laparoscopic distal gastrectomy.

Perirenal fat thickness was measured dorsal to the left kidney as an indicator of visceral fat in patients with gastric cancer who underwent laparoscopic distal gastrectomy. Patients were divided into two groups those with and those without complications. The relationship between perirenal fat thickness and postoperative complications was evaluated.

The optimal cut-off value for predicting morbidity using adipose tissue thickness was 10·7 mm; a distance equal to or greater than this was considered a positive perirenal fat thickness sign (PTS). A positive PTS showed a significant correlation with visceral fat area. Multivariable analysis found that a positive PTS was an independent risk factor for complications (hazard ratio 4·42, 95 per cent c.i. 2·31 to 8·86; P < 0·001).

Perirenal fat thickness as an indicator of visceral fat was an independent predictor of postoperative complications after laparoscopic distal gastrectomy for gastric cancer.

Centralization of pancreatic surgery is currently called for owing to superior outcomes in higher-volume centres. Conversely, organizational and patient concerns speak for a moderation in centralization. Consensus on the optimal balance has not yet been reached. This observational study presents a volume-outcome analysis of a complete national cohort in a health system with long-standing centralization.

Data for all pancreatoduodenectomies in Norway in 2015 and 2016 were identified through a national quality registry and completed through electronic patient journals. Hospitals were dichotomized (high-volume (40 or more procedures/year) or medium-low-volume).

Some 394 procedures were performed (201 in high-volume and 193 in medium-low-volume units). Major postoperative complications occurred in 125 patients (31·7 per cent). https://www.selleckchem.com/products/nu7441.html A clinically relevant postoperative pancreatic fistula occurred in 66 patients (16·8 per cent). Some 17 patients (4·3 per cent) died within 90 days, and the failure-to-rescue rate was 13·6 per cent (17 of 125 patients). In multivariable comparison with the high-volume centre, medium-low-volume units had similar overall complication rates, lower 90-day mortality (odds ratio 0·24, 95 per cent c.i. 0·07 to 0·82) and no tendency for a higher failure-to-rescue rate.

Centralization beyond medium volume will probably not improve on 90-day mortality or failure-to-rescue rates after pancreatoduodenectomy.

Microtubules are the major cytoskeletal component in eukaryotes which are essential for a large spectrum of cellular activities. Monitoring the behavior of microtubules is helpful for a better understanding of the regulatory mechanism governing microtubule architecture and microtubule-based activities. Here, we characterized the binding capability of a modified heptapeptide from tau to both tubulin and microtubules and sought to develop it as a fluorescent peptide for monitoring microtubules.

To deliver the fluorescent peptide into the cells, a cell-penetrating peptide was conjugated to the modified heptapeptide from tau and synthesized. The affinity of the modified heptapeptide was determined by microscale thermophoresis. The microtubule labeling ability was determined by adding the peptide into the polymerized microtubule solutions or cultured HeLa cells.; RESULTS Affinity determination revealed that the tau-derived peptide specifically bound to tubulin. In addition, the peptide was able to label polymerized microtubules in solution, although no obvious microtubule filaments were observed clearly in living cells, probably due to the inadequate affinity.

These results suggest that using a peptide-based strategy for imaging microtubules might be plausible and attempts to improve its affinity is warranted in the future.

Herein, we developed a defect engineering approach which can simultaneously realize O dopant and N defects in the g-C3 N4 framework via an acid-assisted thermal treatment route. The modified g-C3 N4 demonstrated greatly enhanced photocatalytic H2 activity with a H2 evolution rate of 2.20 mmol ⋅ g-1  ⋅ h-1 , which is more than three times higher than that of bulk g-C3 N4 . The mechanism of the enhanced activity was investigated and proposed that the introduction of O dopants and N defects in the g-C3 N4 could optimize the electron structure, up-shift the conduction band, increase the surface area, and thus achieve more efficient separation of photogenerated carriers, stronger reduction ability and abundant active sites for photocatalytic H2 evolution. Thus, defect engineering has been demonstrated to be a prospective strategy to modify the performance of g-C3 N4 for future photocatalytic energy generation.

Perinatal care in the United States is plagued with a high maternal mortality rate and shortages of perinatal care providers. A supportive practice climate is a theoretically based and empirically demonstrated means of improving the quality of care and stabilizing the workforce; however, there has been limited research into the qualities and measurement of a supportive practice climate for midwives.

We developed a self-report instrument, the Midwifery Practice Climate Scale, to measure midwives' perceptions of the supportiveness of their work environments. We tested content and face validity with 2 samples of content experts (n = 6 and n = 14, respectively).

Thirty-four items were created or adapted from nursing instruments. Two items that included language about physicians were removed based upon relevance and redundancy as a result of content and face validity testing.

The findings indicate that the Midwifery Practice Climate Scale is relevant to midwifery and addresses the intended concept of a supportive practice climate for midwives.
