This paper examines the influence of requirement types on the quantity and quality of generated solutions as studied through a user study experiment. A controlled group of students was given a burrito folder design problem with no requirements and asked to sketch solutions. Four experimental groups given different requirement treatments were also asked to sketch solutions for the same design problem. The experimental conditions were functional requirements, non-functional requirements, mixed prioritized requirements and randomly mixed requirements. Analysis of the experimental results reveals that there is a significant difference in quantity of means between the non-functional requirements and the functional requirements groups, with the non-functional group achieving higher quantity scores. In addition, there is a significant difference in quantity in functional requirements and no requirements with the no requirements group achieving higher quantity scores. In terms of quality, there are significant differences in means between the non-functional requirement and functional requirement groups as well as the non-functional and no requirements group. Therefore having non-functional requirements can positively impact the quantity (p-value = 0.09) and the quality of concepts solutions (p-value = 0.018). These findings lead to new future research questions related to understanding exactly how the functionality, in this case functional requirements, influence an engineer’s thinking.

Abstract Introduction GERD is one of the complications of bariatric operations that might affect the quality of life. We aim to perform a retrospective cohort study to determine the incidence of symptomatic GERD following different types of bariatric surgery and which operations are considered a contraindication of GERD. Besides, we are attempting to identify the risk factors of GERD after bariatric surgery. Methods Medical records of 729 patients undergone bariatric operations between January 2010 and June 2019 at Shamir (Assaf Harofeh) Medical Center were reviewed. Results There was a significant difference between the type of bariatric procedure and the incidence of GERD symptoms after the operation. The incidence of symptomatic GERD in patients who underwent SG was 39.9% (p =0.0131). This was significantly higher compared to 16.4% following roux en y gastric bypass, 23.4% following LAGB, and 11% following OAGB. 113 patients out of 718 had a positive swallow test and of these patient 71 developed GERD symptoms post-operatively without correlation to the degree of reflux at the swallow test but with statistically significant correlation to the type of operation especially for SG (P-value <0.001) and to our knowledge this was never reported in the literature. Conclusion SG is a good bariatric procedure option but should be contraindicated in asymptomatic reflux contrast swallow study and symptomatic GERD patients preoperatively because of high levels of symptomatic GERD post-operatively. Asymptomatic reflux at contrast swallow study pre-operatively should be considered a risk factor for GERD after the operation.

Background Microsuture is an essential material for basic microsurgical training. However, it is consumable, expensive, and sometimes unavailable in the microsurgical laboratory. To solve this problem, we developed a microsuture made from human hair and needle gauge. Methods Do-It-Yourself (DIY) microsuture is made from human hair and needle gauge 32G (BD Ultra-Fine Pen Needles 4 mm × 32G). Methods are explained step by step. This DIY microsuture (labeled as “test microsuture”) and nylon 8–0 (Ethilon suture 8–0, labeled as “standard microsuture”) were used for teaching orthopaedic residents to perform arterial anastomosis in chicken thighs. All residents practiced without knowing that “test microsuture” was made from the DIY method. After completing the training, quality of both microsutures was evaluated by questionnaire in topics of (1) thread quality (size, strength, elasticity, handing, knot perform, and knot security), (2) needle quality (size, curve, shape, sharpness, handling, and strength), (3) needle–thread interface (size, strength, and smoothness), and (4) overall quality of microsuture. Each category was evaluated by Likert score (5 = excellent, 4 = good, 3 = fair, 2 = poor, and 1 = very poor). Results The DIY microsuture was performed in three steps: (1) insert human hair into needle gauge by microforceps, (2) bend needle into smooth curve, and (3) disconnect needle and create needle–hair interface. The questionnaire was completed by 30 orthopaedic residents and showed that thread quality of DIY and standard microsuture had “good” and “good-to-excellent” quality (mean Likert score: 3.77–4.23 and 3.80–4.27, respectively, with no statistical difference). Thread–needle interface quality of DIY and standard microsuture also had “good” and “good-to-excellent” quality (Likert score: 3.73–4.20 and 4.07–4.33, respectively, with no statistical difference). Needle part of DIY microsuture had lower quality than standard suture (fair-to-good compared with good-to-excellence quality, score 3.30–3.67 vs. 4.20–4.27, respectively, with a statistically significant difference, p-value < 0.05). However, overall quality of DIY suture and standard microsuture had “good” and “good-to-excellent” (mean Likert score: 3.73 and 4.00, respectively, with no statistical difference). Conclusion The DIY microsuture from human hair and needle gauge could be an alternative for basic microsurgical training with lower cost, easy production, and more availability for use in practice with acceptable quality compared with that of standard microsuture.

Abstract Aim Probability of survival of patients with vulvar cancer directly depends on the lymph node status. Surgery of lymph nodes can be performed as radical inguinofemoral lymphadenectomy or in cases with certain conditions as sentinel lymph node surgery. The aim of this study is to obtain an overview of the intervention-related morbidity and quality of life in patients with vulvar carcinoma after lymphadenectomy. Methods Quality of life and morbidity was compared between patients who underwent radical inguinofemoral lymphadenectomy with those who underwent sentinel lymph node surgery. Results All recorded postoperative complications occur more frequently in the non-sentinel group, Significant difference was shown for the occurrence of lymphedema (p-value = 0.024) and sensitivity loss (p-value = 0.024). Recurrence of disease was more frequent in the non-sentinel group (38 % vs. 20 %, p = 0.621, n.s.) and satisfaction with groin surgery is slightly higher in the sentinel group (94 % vs. 89 %, p = 1.000, n.s.). Conclusion We could demonstrate a significantly lower morbidity of sentinel lymphadenectomy compared to conventional inguinofemoral lymphadenectomy while maintaining the same oncological safety. The low morbidity of sentinel- lymphadenectomy does not seem to influence the postoperative quality of life significantly. However, recording of the individual burden of lymphadenectomy by questionnaires should be optimized.

Patients with functional gastrointestinal tract who are unable to meet their nutritional requirements may benefit from the use of enteral nutrition via feeding tubes which could be nasogastric, percutaneous endoscopic gastrostomy and jejunostomy. Although enteral tube feeding has been shown to promote nutritional status, improve wound healing, and enhance patients’ quality of life (QoL), evidence of tube and feed complications and reduced QoL has also been reported. Despite the increasing prevalence of patients on enteral tube feeding, no systematic review examining the role of enteral tube feeding on patients’ QoL appears to have been published. Aim: The aim of this systematic review is to evaluate the effect of enteral tube feeding on patients’ QoL. Method: Three databases (EMBASE, Pubmed, and PsycINFO) plus Google Scholar were searched for relevant articles based on the Population, Intervention, Comparator, Outcomes (PICO) framework. The review was in line with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and involved the use of synonyms and medical subject headings. In addition, search terms were combined using Boolean operators (AND/OR) and all the articles retrieved were exported to EndNote for de-duplication. Results: Fourteen articles which met the criteria were included and three distinct areas were identified: the effect of early versus late enteral tube feeding on QoL; the QoL of patients on gastrostomy versus standard care, and the effect of enteral tube feeding on QoL. Overall, nine studies reported improvement in the QoL of patients on enteral tube feeding, while five studies demonstrated either no significant difference or reduction in QoL. Some factors which may have influenced these outcomes are differences in types of gastrostomy tubes, enteral feeding methods (including time patients spent connected to enteral feed/pump), and patients’ medical conditions, as well as the generic and/or type of QoL measuring instrument used. Conclusion: Most reviewed studies suggest that enteral tube feeding is effective in improving patients’ QoL. The use of enteral tube feeding-specific QoL measuring instruments is recommended for future research, and improved management strategies including use of mobile enteral feeding pumps should further enhance patients’ QoL. More studies on the effect of delivery systems/enteral feeding pumps on QoL are needed as research in this area is limited.

BACKGROUND: Asthma is the most prevalent chronic disease in the pediatric age group. The disease affects different aspects of the children's lives, such as physical, emotional, social and educational aspects. Thus, more focus has been on the quality of life in these patients rather than the duration of their illness in recent years.AIM: This study examined the different aspects of quality of life in asthmatic children for the first time in this geographic area.METHODS: The study was cross-sectional conducted in 2015-2016. The asthmatic group was 100 patients aged 8 to 12 admitted to the Asthma and Allergy Clinic of Ghaem Hospital (as) in Mashhad with the control group composed of 100 healthy children of the same age and gender. The standard questionnaire pedsQLTM was used for comparing the quality of life of children in the two groups. Statistical analysis was SPSS23 with P-value less than 0.05, which was statistically significant.RESULTS: In each group, 58 patients were boys, and 42 were girls. In a comparison of the quality of life of children, the asthma group with a mean total score of Peds QL 20.99 ± 12.54 compared to the healthy children with a mean total score of Peds QL of 8.8 ± 5.41 had a lower quality of life (P < 0.001). Moreover, regarding various aspects of quality of life asthma group had a lower quality of life in physical performance, emotional performance and performance in school (P < 0.001). Nonetheless, there was no significant difference between the two groups considering social function (P = 0.267). Examining the relationship between Peds QL score of patients with asthma with various variables was indicative of the fact that Peds QL scores were significantly correlated with the gender of the patients, showing better quality of life in the girls (P = 0.001).CONCLUSION: The results indicated that children with asthma have a significantly lower quality of life compared with healthy children of the same age. Also, in examining the different aspects of quality of life, these children had a lower quality of life in physical performance, emotional performance, and performance at school, and were at the level as that of healthy children only in social performance.

BACKGROUND The objective of this study was to test as to whether daily saline nasal irrigation improved sinus symptoms in adult subjects with chronic rhino sinusitis, and also study the safety of saline irrigation, incidence of any complication and improvement in quality of life in these patients. METHODS This was a prospective observational study conducted between two groups of patients at Government TD Medical College, Alappuzha. Patients who satisfied the criteria for diagnosing chronic rhino sinusitis were included in the study. The first group was given saline nasal irrigation with oral drug therapy while the second group was put on oral drugs alone. Each subject was given a pretested, structured questionnaire. Along with socio-demographic information, the questionnaire also contained queries of quality of life measure, compliance of nasal irrigation and adverse effects following its use. RESULTS The pre-treatment scores and post treatment scores were analysed and the results were statistically significant with P values of < 0.001 in all. 77 % of the patients in the saline irrigation group were strictly using saline nasal irrigation which meant a satisfactory compliance and the improvement in post treatment scores was statistically highly significant with a P value of < 0.001. Also there was a statistically significant difference between the mean pre-test and post test scores of the two groups with P value of < 0.001 and t value of 51.942 using the paired t test. CONCLUSIONS Chronic rhinosinusitis has a major negative impact on the healthcare and economy of not only the patients but also of the society. Saline nasal irrigation is an effective yet easy method of therapy in alleviating the symptoms of chronic rhinosinusitis and improving the quality of life in these chronic sufferers.

Abstract: Post-operative infection is still one of the most common nosocomial diseases that can cause great losses because it will increase the length of stay, use of drugs, and reduce the quality of life of the patients. The risk will increase if the number of colonies is> 105 bacteria per gram of tissue. Various ways have been done to reduce the number of bacteria in the operation area, including the use of surgical gloves. This study analyzed the comparison of the level of bacterial colonies that grew on the surface of single, double, and orthopedic surgical gloves in closed fracture management for more than 2 hours at Hasan Sadikin Hospital. The statistical analysis was done with p-value = 0.011 (<0.05), which means a significant difference in the number of germ colonies that grow between single, double, and orthopedic gloves. Double gloves and orthopedic gloves have a better ability to reduce bacterial colony growth. Meanwhile, there was no significant difference in the number of bacterial colonies formed between double gloves and orthopedics. Perforation is a factor affecting the number of germ colonies that formed. The use of double gloves and orthopedic gloves in closed fracture surgery for more than 2 hours shows the number of bacterial colonies formed is less than single gloves. There was a significant difference in the rate of perforation between standard surgical gloves and orthopedic gloves. Keywords: Bacteria colony, Single glove, Double glove, Orthopaedic glove, Perforation

The increased focus of people on the quality of health care in recent years has led hospital owners to develop strategies and policies to improve medical services through the establishment of new hospitals. For hospitals to be competitive, the hospitalʼs location and proximity to potential patients are considered crucial factors in establishing new hospitals. In this context, evaluating and selecting the most suitable hospital location to establish a new hospital from the multicriteria decision-making (MCDM) perspective is a priority for the entrepreneurs or government to gain a competitive advantage. Therefore, this study aims to present a systematic literature review of the hospital location selection problem considering the applied methods and application areas. The preferred reporting items for systematic review and meta-analysis statement (PRISMA) are used as a reference framework. Initially, known electronic databases (Web of science, IEEEXplore, Scopus, Science direct, and Google Scholar) were searched up to the early 2021. A number of 47 articles are selected and analyzed under this systematic framework based on inclusion-exclusion points. State-of-the-art developments in adopting MCDM methods and their fuzzy extensions are summarized. All the articles have been examined in a systematic taxonomy to find answers to six research questions (trend, country of origin, outlet journal, MCDM methods used, MCDM environment and criteria type, and decision criteria used). Results show that (1) AHP and GIS-based MCDM models are the most contributing approaches to the solution of this problem, (2) location selection criteria are mostly cost, demand, environment, population, government, competition in the market, and distance to some important places, (3) the fuzzy structure is also preferred in addition to the MCDM structure depending on the crisp data type, and (4) the location selection criteria are mostly considered subjective. We pay attention to promising directions that can dominate future research in this field from a methodological or applicability perspective. This study shows the current views and opportunities for researchers and practitioners and acts as a guide to encourage more creative studies in this field.

Background: CF is a chronic, multisystem genetic disease with a wide variability in clinical severity. CF is a disease of exocrine gland function that involves multiple organ systems but chiefly results in chronic respiratory infections, pancreatic enzyme insufficiency, and associated complications in untreated patients. Many studies explained the lower QOL among adults with CF. in GS there is no previous studies concerned with measuring QOL among CF children Aim of the Study: The aim of this study was to assess the QOL among children with CF. Methodology: The study was descriptive, analytical and cross sectional studies. The study involves all 36 children with CF (less than 12 years old) who attained CF friends center; community based center in Gaza. The researchers uses the questionnaire which included demographic & illness related variables and Quality of life domains (physical, emotional, social and school). Reliability coefficient for the questionnaire was good (Cronbach alpha =0.833). Results and Conclusion: About 61% of the study population were males and 39% were females. Approximately 47% of them were less than 9 years and 53% were more than 9 years. About 41.7% of the study population from Gaza, 25.0% from middle zone, 13.9% from Rafah, 11.1% from Khanyounis and 8.3% from North of Gaza. Housing classification was 38.9%, 33.3% and 27.8 % for property house, renting house and family house respectively. Most of their parents had low educational levels and the majority of them were unemployed and have a monthly income less than 1200 NIS. About 61% of them have another sibling with CF. the majority of them receive Creon at a regular basis. The most common disease associated with them was Respiratory problem with 43.2%, 38.3% had gastrointestinal disease, 14.8% had heart disease and 3.7% had Diabetes Mellitus. The overall perception of the children regarding QOL was low (55%). The social functions was the highest (61.6%), physical functions (55.2%), school function (50.6%), and emotional function (48.8%). The result presented below show that no significant difference in QOL between socio-demographic data (p-value > 0.05) except the difference for QOL between age groups) p-value =0.001). Children older than 9 years old (2.95±0.3) have QOL more than children under nine years of age (2.53±0.4) and this difference was statistically significant as (P value = 0.02 < 0.05). It is also clear that QOL in males are more than female but this difference was not statistically significant. There is a positive correlation with a highly significant difference between QOL and the 4 domains and between domains with each other. Social performance was high correlated with school performance (r = 0.706) while the lowest correlation was between physical and school performance with no significant (p-value =0.065). Recommendations: The study recommend the importance of initiating a program to enhance the QOL for children with CF and focusing on the emotional health for those children as it was the least one perceived.
