Background: European Society of Gastrointestinal Endoscopy( ESGE) recommends needle-knife fstulotomy(NKF) as the preferred precut technique in cases when standard cannulation techniques fail. Despite scarce scientifc evidence, flat and diverticular papillae are thought not to be ideal for NKF, as they are associated with poor outcomes. The present study aimed to determine the outcomes of the use of NKF in relation to flat and intradiverticular papillae. Methods: This prospective multicenter study enrolled consecutive patients, evidencing na?ve flat(group A, n = 49) or diverticular papilla(group B, n = 28), who underwent NKF after failure of standard cannulation techniques. Diverticular morphology was subdivided into intradiverticular(group B1, n = 14) and diverticular border papillae(group B2, n = 14), using a previously validated endoscopic classifcation of the major papilla. The success of biliary cannulation at initial endoscopic retrograde cholangiopancreatography(ERCP), overall biliary cannulation, overall cannulation time, and the rate of adverse events were assessed in the study. Results: The initial cannulation rates were 93.9%, 64.3% and 71.4% for group A, B1, and B2, respectively( P = 0.005);overall cannulation rates after a second ERCP were 98.0%, 92.9% and 85.7%, respectively( P = 0.134). Adverse events occurred in 11.7% of patients, with post-ERCP pancreatitis(PEP) being the most common adverse event(10.4%). Although there was a trend towards a higher incidence of PEP in flat papillae, univariate and multivariate analyses did not show any signifcant relationship between pancreatitis and trainee involvement, papillary morphology, nor overall cannulation time. Conclusions: Although flat papillae are associated with high success rates of biliary cannulation using NKF, the rate of PEP is not negligible. NKF is feasible in diverticular papillae, but it is associated with a modest success rate in the initial ERCP.

Nutritional Screening Tools in Institutionalized People: A Case Study of Using Nutritional Risk Screening (NRS 2002) and Mini Nutritional Assessment (MNA)

Food and Nutrition Sciences 2024年第7期15卷 565-575页

Nutritional status expresses the physiological and nutritional needs to maintain the composition and adequate functioning of the organism. NRS 2002 and MNA protocols were applied to short-term institutionalized patients in Rio Verde (Brazil). Older adults and people with special needs of all ages, both sexes, regardless of possible pathology they may have, except if it causes contagion, were included, patients duly authorized by the person responsible for the institution and who were able to undergo evaluation. Thirty-eight patients from the institution were evaluated, of which ten were excluded from the research according to pre-established criteria. More than 50% of participants were male, with an overall average age of 63.43 years. The characteristics related to nutritional status by NRS 2002 and MNA showed that the risk of malnutrition and its absence are associated with a wide age range. The MNA presents a more nuanced nutritional risk classification, showing that even 61% of the 96% of participants who would be out of nutrition risk, according to the NRS 2002, are “at risk of malnutrition”. Applying the MNA can demonstrate more conservative results than the NRS 2002.

The Potential Game-Changer:A Concept-to-Proof Study on D:A Heterojunction-Free Organic Photovoltaics

Chinese journal of Chemistry 2024年第3期42卷 252-258页

Since 1986,the donor-acceptor (D:A) heterojunction has been regarded a necessity for high-efficiency organic photovoltaics (OPVs),due to its unique advantage in compensating the intrinsic limitations of organic semiconductors,such as high exciton binding energy and poor ambipolar charge mobility. While this adversely causes tremendous non-radiative charge recombination and instability issues,which currently become the most critical limits for commercialization of OPVs. Here,we present a concept-to-proof study on the potential of D:A heterojunction free OPV by taking advantage of recent progress of non-fullerene acceptors. First,we demonstrate that the “free carriers” can be spontaneously generated upon illumination in an NFA,i.e.,the 6TIC-4F single layer. Second,the 6TIC-4F layer also exhibits good ambipolar charge transporting property. These exceptional characteristics distinguish it from the traditional organic semiconductors,and relieve it from the reliance of D:A heterojunction to independently work as active layer. As a result,the subsequent OPV by simply sandwiching the 6TIC-4F layer between the cathode and anode yields a considerably high power conversion efficiency ~1%. Moreover,we find the D:A heterojunction free device exhibits two order of magnitude higher electroluminescence quantum efficiency and significantly reduced VOC loss by 0.16 eV compared to those of the D:A BHJ structure,validating its promise for higher efficiency in the future. Therefore,our work demonstrates the possibility of using D:A heterojunction-free device structure for high performance,that can potentially become the next game changer of OPV.
