Gelatinization and retrogradation, influenced by amylose and amylopectin ratio, are important characteristics for elaboration starch hydrogels. The objective of this study was to evaluate the influence of amylose content and the gelatinization method on the physicochemical characteristics of native and cross-linked rice starch hydrogels. The native and cross-linked starches were gelatinized with heating or alkaline solution, added polyvinyl alcohol, frozen and then freeze-dried. The cross-linked starch had a low final viscosity (101...

BACKGROUND CONTEXT: Relative value units (RVUs) are a compensation model based on the effort required to provide a procedure or service to a patient. Thus, procedures that are more complex and require greater technical skill and aftercare, such as multilevel spine surgery, should provide greater physician compensation. However, there are limited data comparing RVUs with operative time. Therefore, this study aims to compare mean (1) operative times; (2) RVUs; and (3) RVU/min between posterior segmental instrumentation of 3-6, 7-12, and ≥13 vertebral segments, and to perform annual cost difference analysis...

BACKGROUND: Medicaid reimbursements are determined by each state and are subject to variability. We sought to quantify this variation for commonly performed inpatient orthopaedic procedures. METHODS: The 10 most commonly performed inpatient orthopaedic procedures, as ranked by the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample, were identified for study. Medicaid reimbursement amounts for those procedures were benchmarked to state Medicare reimbursement amounts in 3 ways: (1) ratio, (2) dollar difference, and (3) dollar difference divided by the relative value unit (RVU) amount...

INTRODUCTION: To determine the effort required to provide a service, the United States Medicare uses Relative Value Units (RVUs). Consequently, higher RVUs are assigned to the procedures or services that require more effort, which ultimately means the physician will be properly compensated for the additional effort required. In total ankle arthroplasty (TAA), revision cases usually are more technically challenging and require more effort than primary TAA. Therefore, the purpose of this study was to compare the: 1) RVUs; 2) length-of-surgery; 3) RVU per unit of time between primary and revision total ankle arthroplasty; and 4) the individualized idealized surgeon annual cost difference analysis...

Native acorn starch had high purity and the granules were mainly elliptical and spherical with the mean diameter of 7.32 μm. Hydrothermal modifications slightly changed the morphology. The solubility, swelling properties and amylose leaching of acorn starch were mostly influenced by Heat-moisture treatment (HMT). XRD pattern of native starch (C-type) did not change on hydrothermal modifications, but native and annealing (ANN) modified starches showed the most crystallinity. DSC results showed that the gelatinization temperatures and enthalpy of native starch were 59...

BACKGROUND: In total knee arthroplasty (TKA), revision cases are often technically more challenging, and require more operative time and aftercare than primary cases. These time and effort differences should therefore be appropriately compensated for when using the relative value unit (RVU) system. Therefore, the purpose of this study is to compare the mean (1) RVUs; (2) operative times; and (3) RVU/min; and (4) perform an individualized idealized surgeon annual cost difference analysis for primary vs revision TKA...

The SEM of starch from five EAHB cultivars showed a mixture of irregular granule shapes with smooth surfaces. The starches' average diameter size ranged between 16.31 and 21.98 μm. The moisture, protein, and ash content of the starches were: 11.12%-11.84%, 0.1% and 0.23%-0.47% respectively. The amylose content of these starches was between 11% and 13%. The starches peak viscosity ranged between 488.42 and 558.66 RVU. The EAHB starches exhibited relatively low pasting temperatures (<75°C), a high peak viscosity (488...

STUDY OBJECTIVE: Three observational studies at large teaching hospitals found that reducing turnover times resulted in the surgeons performing more cases. We sought to determine if these findings are generalizable to other hospitals, because, if so, reducing turnover times may be an important mechanism for hospitals to use for growing caseloads. DESIGN: Observational cohort study. SETTING: 116 hospitals in Iowa with inpatient or outpatient surgery from July 1, 2013 through June 30, 2015...

Amadumbe, known as taro is a traditional crop mainly grown for subsistence in Southern Africa. In this study, chemical composition and functional properties of nine amadumbe genotypes grown at two distinct locations were investigated. Carbohydrate contents (73-81%) of amadumbe genotypes were substantially high and varied with growth location. Protein contents ranged from 8-12% and fat was very low (less 1%) in all genotypes. Major minerals in flours were K, P, Mg and Ca, but these were present at varying levels depending on growth locations...

BACKGROUND: Relative value units (RVUs) are used to evaluate the effort required for providing a service to patients in order to determine compensation. Thus, more complicated cases, like revision arthroplasty cases, should yield a greater compensation. However, there are limited data comparing RVUs to the time required to complete the service. Therefore, the purpose of this study is to compare the (1) mean RVUs, (2) mean operative times, and (3) mean RVU/minute between primary and revision total hip arthroplasty (THA) and (4) perform an individualized idealized surgeon annual cost difference analysis...

The changes in sorghum [Sorghum bicolor (L.) Moench] proteins during germination and the resultant effects on the physicochemical properties of sorghum flour were studied using non-germinated grains as a control. Results showed that flour obtained from germinated sorghum grains had lower protein levels, higher protease levels, and higher free amino nitrogen content compared with the control. There was an increase in the albumin and globulin protein fractions and a decrease in kafirin. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis indicated that this decrease was the result of a decrease in γ-kafirins, while microscopy found that a continuous protein network was formed...

STUDY OBJECTIVE: Percentage utilization of operating room (OR) time is not an appropriate endpoint for planning additional OR time for surgeons with high caseloads, and cannot be measured accurately for surgeons with low caseloads. Nonetheless, many OR directors claim that their hospitals make decisions based on individual surgeons' OR utilizations. This incongruity could be explained by the OR managers considering the earlier mathematical studies, performed using data from a few large teaching hospitals, as irrelevant to their hospitals...
