Use of health-related quality of life tools in hepatobiliary surgery

引用

Hepatobiliary & Pancreatic Diseases International 2008年第2期7卷 135-137页

作者： Muhammad Shafique sajid Mawara Iftikhar Jasmin Rimple Mirza Khurrum Baig Department of Surgery Worthing Hospital West Sussex BN11 2DH UK

BACKGROUND: The objective of this article is to review the literature and discuss the various tools used in hepatobiliary surgery for the measurement of health related quality of life (HR-QOL) and highlight various outcome variables that affect the HR-QOL among patients with common hepatobiliary disorders. DATA SOURCES: We reviewed HR-QOL articles published in the last 20 years on different hepatobiliary curative or palliative procedures in all languages. RESULTS: HR-QOL is a questionnaire tool which is utilized to assess the changes in the health status of patients after a hepatobiliary intervention. These surveys are of increasingly importance, as health care providers are challenged to justify treatment approaches and rationale for any surgical intervention. These HR-QOL tools are very helpful for the evaluation of subjective outcome of common hepatobiliary procedures like gastrointestinal quality of life index (GIQLI) for cholecystectomy, functional assessment in cancer therapy (FACT) for liver resection, short form 36 (SF-36) for liver transplantation, and quality of life questionnaire for patients with pancreatic cancer (QLQ-PAN). CONCLUSIONS: Use of validated and reliable health instruments in hepatobiliary surgery is directed at measuring the impact in a reproducible and valid fashion. Curative or palliative procedures should be offered to the patients of hepatobiliary disorders after the assessment by HR-QOL tools. Because the impairments of function that may occur after different operations vary considerably, an operation-specific assessment of HR-QOL for each type of surgical procedure is becoming an essential principle to follow in a successful healthcare system.

The equations for two-dimensional flow of an upper convected Maxwell （UCM） fluid in a rotating frame are modeled. The resulting equations are first simplified by a boundary layer approach and then solved by a homotopy analysis method （HAM）. Convergence of series solution is discussed through residual error curves. The results of the influence of viscoelastic and rotation parameters are plotted and discussed.

Phenotypic variations of wheat cultivars from the North China Plain in response to cadmium stress and associated single nucleotide polymorphisms identified by a genome-wide association study

引用

Pedosphere 2022年第4期32卷 555-564页

作者： Imdad Ullah ZAID sajid Hanif MUHAMMAD Na ZHANG Xin ZHENG Likun WANG Xiaofang LI Centre for Agricultural Resources Research Institute of Genetics and Developmental BiologyChinese Academy of SciencesShijiazhuang 050021China University of Chinese Academy of Sciences Beijing 100049China

Understanding the genetic mechanisms for cadmium (Cd) uptake and translocation in common wheat (Triticum aestivum) is of significance in food Cd contamination control. In this study, a diverse panel of 132 wheat cultivars was collected from the North China Plain. The cultivars were evaluated in terms of their phenotypic variations in response to Cd stress and subjected to a genome-wide association study (GWAS) to identify single nucleotide polymorphisms (SNPs) associated with the phenotypic variations at the seedling stage. Significant phenotypic variations with high heritability were observed among the wheat cultivars exposed to 40 μmol L-1 Cd for the studied traits, including root length (RL), shoot length (SL), root and shoot dry biomasses (RDW and SDW, respectively), root and shoot Cd concentrations (RCD and SCD, respectively), and Cd translocation factor (TF). Mean RCD, SCD, and TF ranged from 1.0 to 33.8, 0.125 to 2.022, and 0.009 to 0.321 mg g-1, respectively. Cluster analysis showed that wheat cultivars with higher RL, SL, RDW, and SDW under Cd stress were able to accumulate more Cd in root, leading to a lower Cd TF. Mixed linear model-based association analysis detected 17 novel significant marker-trait associations (MTAs), four of which were significant at a genome-wide scale. Most of the significant MTAs controlled Cd TF and explained 17.17%–26.47% of the phenotypic variations. Some of the SNP loci were physically close to a reported Cd-related quantitative trait locus or gene on wheat chromosomes. Results of this study provided a list of wheat cultivars with the potential of low Cd accumulation and enriched our knowledge on the genetic basis of Cd uptake and translocation in wheat. Pyramiding breeding of superior alleles detected in this study may additionally reduce Cd accumulation of improved wheat cultivars with excellent agronomic traits.
