Commercial cold beverages thickened with a xanthan gum (XG)-based food thickener were examined at different thickness levels by using the simple, cost-effective syringe flow test (SFT) developed by the International Dysphagia Diet Standardization Initiative (IDDSI). We prepared cold thickened beverage (CTB) samples with different thickener concentrations and measured them by extrapolating the viscosity range (51–350 mPa·s) for nectar-like consistency. CTBs were also measured via the line-spread test (LST), and the flow distance value (cm) by LST and the volume remaining (mL) in the syringe by SFT was correlated with the apparent viscosity (ηa,50). Plots comparing ηa,50 with SFT or LST values showed good exponential relationships between the measurements. The SFT showed a better relationship (R2 = 0.928) than LST (R2 = 0.825), indicating that the former can predict the viscosity better in the range for nectar-like consistency. In particular, the SFT showed a significant difference (R2 = 0.964) compared to the LST (R2 = 0.709) for thickened protein-based beverages. These results suggest that the SFT using the IDDSI methodology is a more suitable instrument than the LST for accurately evaluating the viscosity of XG-based CTBs with nectar-like consistency.

ABSTRACT Objective: to investigate whether two different syringes yield different results in the International Dysphagia Diet Standardization Initiative (IDDSI) flow test to evaluate liquid consistency. Methods: two 10-mL syringes (Bencton and Dickinson, manufactured in the United States, and Saldanha Rodrigues, manufactured in Brazil) were compared. Flow rate of water added with food thickener (maltodextrin, xanthan gum and potassium chloride) at three concentrations, and of barium sulfate at three concentrations was measured immediately after preparation and at 8 hours and 24 hours thereafter. Results: flow rate of both water and barium sulfate was higher with the Bencton and Dickinson syringe, with discrepancies between the two syringes in the classification of fluid consistency according to the IDDI framework. Conclusion: in the evaluation of the consistency of liquids by the IDDSI flow test, a Bencton and Dickinson syringe should be used, following the recommendations of the IDDSI group.

Background and aim: Hypotension during cesarean section (CS) under spinal anesthesia has been a subject of scientific study for more than 50 years and the search for the most effective strategy to achieve hemodynamic stability remains challenging. Aim: The study was carried out to apply leg wrapping technique for the prevention of spinal-induced hypotension (SIH) during CS.Methods: Randomized Controlled Trial design was utilized at cesarean delivery operating room Mansoura General Hospital in El-Mansoura City during the period from May 2018 to November 2018. A purposive sample of 88 pregnant women, assigned randomly to an intervention group (n = 44) in which their legs wrapped with elastic crepe bandage and control group (n = 44) in which no wrapping was done. Data collected for maternal, neonatal hemodynamic and signs of hypotension, the feasibility of application and cost analysis.Results: There was a statistically significant difference in the incidence of SIH and Ephedrine use among both groups (18.20% in leg wrapping group whereas 75% in control group). In addition, neonatal acidosis and NICU admission were less among leg wrapping group (11.40%, 9.10% respectively). Economically, leg wrapping technique was cost effective compared to the cost of the hospital regimen for treating SIH and admission to (NICU).Conclusion and recommendations: Leg wrapping technique was cost effective and an efficient method for decreasing SIH, neonatal acidosis and Ephedrine administration. It is recommended to apply leg wrapping technique in maternal hospitals' protocol of care for decreasing SIH during CS.

Natural stoppers are a magnificent closure for the production of aging wines and unique wines, whose application is limited by the availability of raw materials and more specifically of cork sheets of different thickness and quality. The growing demand for quality wine bottle closures leads to the search for alternative stopper production. The two-piece stopper is an alternative since it uses non-usable plates in a conventional way for the production of quality caps. The present study has analyzed the impact of the manufacture of these two-piece stoppers using different methodologies and for different dimensions by developing an LCA (Life Cycle Assessment), concluding that the process phases of the plate, its boiling, and its stabilization, are the phases with the greatest impact. Likewise, it is detected that the impacts in all phases are relatively similar (for one kg of net cork produced), although the volumetric difference between these stoppers represents a significant difference in impacts for each unit produced.

OBJECTIVES: Shoulder pain is a common musculoskeletal disorder, which carries a high cost to healthcare systems. Exercise is a common conservative management strategy for a range of shoulder conditions and can reduce shoulder pain and improve function. Exercise classes that integrate education and self-management strategies have been shown to be cost-effective, offer psycho-social benefits and promote self-efficacy. This study aimed to examine the effectiveness of an 8-week educational and exercise-based shoulder rehabilitation programme following the introduction of evidence-based modifications. METHODS: A retrospective evaluation of a shoulder rehabilitation programme at X Trust was conducted, comparing existing anonymised Shoulder Pain and Disability Index (SPADI) and Patient-Specific Functional Scale (PSFS) scores from two cohorts of class participants from 2017-18 and 2018-19 that were previously collected by the physiotherapy team. Data from the two cohorts were analysed separately, and in comparison, to assess class efficacy. Descriptive data were also analysed from a patient satisfaction survey from the 2018-19 cohort. RESULTS: A total of 47 patients completed the 8-week shoulder rehabilitation programme during the period of data collection (2018-2019). The 2018-19 cohort showed significant improvements in SPADI (p 0.001) and PSFS scores (p 0.001). No significant difference was found between the improvements seen in the 2017-18 cohort and the 2018-19 cohort. 96% of the 31 respondents who completed the patient satisfaction survey felt the class helped to achieve their goals. CONCLUSION: A group-based shoulder rehabilitation class, which included loaded exercises and patient education, led to improvements in pain, disability and function for patients with rotator cuff related shoulder pain (RCRSP) in this outpatient setting, but anticipated additional benefits based on evidence were not observed.

A Prospective Study

This prospective non-randomised two-cohort study compares the use of an absorbable suture (Poliglecrapone [Monocryl]: Group A) and a non-absorbable suture (Polyamide [Ethilon]: Group B) in wound closure after elective carpal tunnel decompression. The primary outcome was scar cosmesis as assessed by the Stonybrook Scar Evaluation Scale (SBSES); the financial cost of wound closure was compared as a secondary outocome. All fifty patients completed follow-up. At six weeks, there was no significant difference in the two groups regarding scar tenderness (p = 0.5), although residual swelling was more evident in the absorbable group (p = 0.2). The mean SBSES score at six weeks was 4.72 in Group A, and 4.8 in Group B (p = 0.3). The unit cost per closed wound of Monocryl was three times than Ethilon (p < 0.05). Ethilon is thus cost-effective without compromising the cosmetic outcome, and we recommend using this as the preferred suture for closure of carpal tunnel wounds.

Background: The objective of this study was to determine the comparative cost-effectiveness of performing initial revision finger amputation in the emergency department (ED) versus in the operating room (OR) accounting for need for unplanned secondary revision in the OR. Methods: We retrospectively examined patients presenting to the ED with traumatic finger and thumb amputations from January 2010 to December 2015. Only those treated with primarily revision amputation were included. Following initial management, the need for unplanned reoperation was assessed and associated with setting of initial management. A sensitivity analysis was used to determine the cost-effectiveness threshold for initial management in the ED versus the OR. Results: Five hundred thirty-seven patients had 677 fingertip amputations, of whom 91 digits were initially primarily revised in the OR, and 586 digits were primarily revised in the ED. Following initial revision, 91 digits required unplanned secondary revision. The unplanned secondary revision rates were similar between settings: 13.7% digits from the ED and 12.1% of digits from the OR ( P = .57). When accounting for direct costs, an incidence of unplanned revision above 77.0% after initial revision fingertip amputation in the ED would make initial revision fingertip amputation in the OR cost-effective. Therefore, based on the unplanned secondary revision rate, initial management in the ED is more cost-effective than in the OR. Conclusions: There is no significant difference in the incidence of unplanned/secondary revision of fingertip amputation rate after the initial procedure was performed in the ED versus the OR.

To explore the effect of thickness on the fracture strength and failure modes of zirconia crowns, four crown models with different thickness (1.2 mm, 1.0 mm, 0.8 mm, 0.6 mm) with the same shape were designed by Dental Designer software in CAD/CAM system. They were manufactured to 40 zirconia crowns by CAM carving machine. The fracture strength and the failure modes of each crown was measured, while porcelain fused to metal (PFM) crowns as control. The average fracture strength of different zirconia crowns were recorded as below: 1308.38 ± 111.38 N (Group 0.6 mm), 1841.60 ± 68.21 N (Group 0.8 mm), 2429.88 ± 315.03 N (Group 1.0 mm), 3068.31 ± 233.88 N (Group 1.2 mm). There was no significant difference between Group 1.0 mm and Group 1.2 mm (P > 0.05), and statistical significance was obtained among every other two groups (P < 0.05). The failure modes of different thickness zirconium crowns are similar. There are more broken pieces from thicker crowns compared to thinner ones. It is concluded that the thickness can influence the fracture strength of zirconia crown. With the increase of the thickness, the fracture strength of the zirconium crowns also increases. We recommend zirconia crowns thicker than or at least 1.0 mm in dental practice.

Blood Flow Measurements

Thirty-five patients with normal renal allografts as well as 10 healthy volunteers with normal native kidneys were examined by duplex sonography. Blood flow measurements were performed in the main renal artery as well as in segmental, interlobar and arcuate arteries. In both groups the normal range of variation in blood flow was defined by using the resistive index (RI). Doppler wave forms and RI of main renal arteries were both similar to those of their branches. In renal allografts as well as in native kidneys the blood flow pattern showed a rapid up-slope in systole followed by a gradual down-slope in early diastole, with a persistent flow throughout diastole. In addition, there was no significant difference in the RI between allografted and native kidneys. The interobserver variability was less than 10 per cent. The mean RI was 0.68 using all data points. Vascular rejection in 11 patients could be discriminated significantly (p<0.001). Duplex sonography is useful in evaluating renal blood flow. This simple and non-invasive technique seems to be useful in long-term follow-up of renal allograft recipients.

Teaching Programs

Unlike distance education institutions in developed countries Sukhothai Thammathirat Open University makes very limited use of assignments in its teaching programs. The main means of interaction between tutors and students consists of free face-to-face tutorials conducted three times per semester in provincial centers throughout the country. In courses with low enrolments (less than 1000 students) such tutorials have recently been deemed not to be cost effective. Alternative regional or central intensive programs have been developed. These involve 20 hours of tutorial classes and assignment work over two weekends in the final month of the semester and count for 30% of the assessment. A small charge is made for registration. The Mathematics for Social Science course was affected by this change. Since mathematics is a difficult subject for students, (only about 30% normally passed the course) the special tutorial program was used to help students in the second semester of 2006. Students were more interested in this approach than in the regular face-to-face tutorials. After the project was advertised, 98 students applied. While this was more than three times the number who had attended the free tutorials in the previous semester, it was not sufficient to justify tutorials in the four regions. Instead, three classes were conducted in Bangkok. Only 71 of the original applicants attended. During the program the better students were asked to assist those who needed help. Student questionnaires indicated that more than half identified themselves as weak in mathematics, most had completed year 12 and just over three-quarters had never attended regular face-to-face tutorials. They were asked to rank items about the classes on a five-level scale. The availability of up to 30% of the marks for the course was the major attraction. Most indicated that they were pleased with the classes, and gained more knowledge; while assignments, as well as the solutions given after submission, helped them understand the contents. Having classmates help them with learning also encouraged them with their study. They felt that they needed more time to study and do assignment work, and would like more marks to be allocated for the assignments. It was found that the achievement of students who attended the special tutorial classes was significantly higher than that of those who did not. The pass rate in this semester dramatically increased compared to the previous semester, 50.72% and 30.34% respectively. But when comparing students' final exam scores for both groups, it was found that there was no significant difference in the scores. However students were satisfied with these special tutorial classes.
