Abstract
Background

Team-based learning (TBL) is widely used in health professions education. However, TBL implanted in pediatric clerkship is rare. Here we explore the efficacy and feasibility of TBL in pediatric clerkship.
Methods

We retrospectively reviewed the TBL course in pediatric clerkship in between August and October in 2019, at Children’s Hospital, Zhejiang University School of Medicine, Hangzhou, China. TBL group (with 107 students) compared to students from the prior year with case-based discussion (Control group, with 222 students). The learning outcomes were measured as theoretical exams when pediatric clerkship ended. The satisfaction of TBL was evaluated by an anonymous questionnaire in the TBL group.
Results

The grade point average before pediatric clerkship in the TBL group (3.58, 3.04–3.96) was similar to in Control group (3.62, 3.16-4.00). However theoretical exams in the TBL group (76, 67–82) were significantly higher than the control group (72, 64–78) (P = 0.002). Besides, 92.5% of students in the TBL group responded to the questionnaire with a satisfaction higher than 90%.
Conclusions

Our study demonstrated that TBL in pediatric clerkship was effective and feasible with a better learning outcome.

Abstract
Background: One of the common side effects of radiotherapy and chemotherapy in patients with head and neck cancer is oral mucositis. This painful complication restricts the ability to eat and drink and increases the risk of oral infections. The aim of this study was to investigate the effect of doxepin oral rinse 0.5% in comparison with persica mouthwash on reducing the pain of oral mucositis in patients with head and neck cancer after radiotherapy and chemotherapy. Methods: This clinical trial was performed on 56 patients admitted in the oncology ward of Shahid Sadoughi Hospital and Shahid Ramezanzadeh radiotherapy center in Yazd, who received more than 45 gray of radiation and had mucositis and their pain score was more than 4 on the basis of the Visual Analogue Scale (VAS). Patients were randomly divided into two groups of persica and doxepin 0.5%. The data collection tool was a questionnaire including visual analogue scale for pain, taste satisfaction and possible complications. Data were analyzed by using SPSS19 software and Chi-square test. Results: There was no significant difference between the mean score of pain in doxepin and persica groups 5,15,30, 120,240 minutes and 24 hours after taking the mouthwash; just in the doxepin group, the mean of pain reduction 60 minute after taking the mouthwash was higher than persica group (P> 0.05). There was no significant difference between the mean score of burning sensation in doxepin and persica groups30,60,120,240 minutes and 24 hours after taking the mouthwash; just in the pesica group, the mean of burning sensation reduction 5,15minutes after taking the mouthwash was lower than doxepin group The level of taste satisfaction and drowsiness in the doxepin group was significantly higher than persica group. (P >0.05) Conclusion: Persica mouthwash, like doxepin mouthwash, was effective in reducing the mucositis pain in patients and just in the doxepin group reduction in pain after 60 minutes was higher than perisca group

Abstract
COVID-19 is a global concern nowadays, and the psychological impact of the pandemic cannot be overlooked. People are under insurmountable pressure, which may lead to psychological problems such as anxiety and depression. The purpose of this study was to evaluate the mental health of spinocerebellar ataxia (SCA) patients during COVID-19 pandemic and to analyze its influencing factors. We conducted an online questionnaire survey among 307 SCA patients from China. The contents of the questionnaire included general information, the self-rating anxiety scale (SAS), the self-rating depression scale (SDS). The relevant influencing factors included COVID-19 risk factors, age, gender, BMI (body mass index), educational background, disease course, and score of the scale for the assessment and rating of ataxia (SARA). Results indicate the 307 SCA patients had an anxiety rate of 34.9%, along with a depression rate of 56.7%. Their SAS and SDS scores were significantly higher than those of the Chinese norm group (SAS: 45.8±10.1 vs. 37.2±12.6, P < 0.01; SDS: 55.1±12.2 vs. 41.9±10.6, P < 0.01). Risks of exposure to COVID-19, educational level, and disease course may be factors affecting mental health status. The existence of a positive correlation among the scores of SARA, SAS and SDS scale was demonstrated, the higher the SARA score, the higher the risk of anxiety and depression. Anxiety and depression were more prevalent in SCA patients compared with the normal population, and depression was more common than anxiety during this pandemic. More psychological attention should be paid to SCA patients during COVID-19 pandemic.

Replacement therapy for chronic kidney disease using haemodialysis involves the elimination of excessive toxic fluids and toxic metabolic end products from the body. Worldwide, gender significant differences exist with regard to the epidemiological aspect, evolution and blood parameters of chronic renal failure disease. In the present retrospective study, 289 medical files of adult patients (154 men and 135 women) aged 20 to 78 years were investigated to understand the relationship between gender difference and blood parameters in patients with chronic renal failure undergoing haemodialysis in north western Algeria. Our results revealed significant higher levels of haemoglobin (p=0.003), haematocrit (p=0.005), creatinine (p<0.001) and uric acid (p=0.037) in men comparing to women. However, women serum samples were characterized by higher significant level of platelets (p=0.002). No significant differences (p˃0.005) were observed between the two genders regarding the other parameters of blood count formula, liver function parameters, urea, mineral status (calcemia and phosphoremia), basic biochemical levels (glycaemia and lipids), C-reactive protein (CRP) and parathyroid hormone (PTH). In dialysis patients, and despite the fact that some serum parameters vary significantly, the majority of the parameters recorded were often high in the males compared to the female gender. This finding may be due to the existence of specific confounding prognostic factors for each sex, which may or may not compensate for each other, therefore, ultimately, leading to overall non-significance.

This study evaluated the effect of Chitosan and Aloe vera gel coatings on the preservation of selected cucumber samples. Chitosan was produced from orange-crab shells with 76% degree of deacetylation while homogenized Aloe vera gel extracted from the plants was thermally pre-treated at 70 Â°C for 30 minutes. Coatings were applied using dipping techniques and air-dried before storage in discrete plots under ambient conditions. The study estimated physicochemical, nutritional and microbiological qualities of the coated and uncoated samples for a period of 4 weeks using standard procedures. Chitosan and Aloe vera gel had antimicrobial effect on the cucumber samples at week three while Chitosan- Aloe vera mix had more antimicrobial effect on the cucumber samples at week four of storage period. Eight bacterial and seven fungal isolates were obtained from the chitosan and Aloe vera coatings on the cucumber samples namely Aeromonas, Bacillus, Pseudomonas, Escherichia, Proteus, Klebsiella, Serratia, Enterobacter, Aspergillus, Penicillium, Fusarium, Rhizopus and, Saccharomyces; with Bacillus subtilis and Aspergillus niger as most occurring bacterial and fungal species respectively. Chitosan, Aloe vera and Chitosan-aloe vera mix coated samples had moisture content, protein content and carbohydrate retention of 95.09Â±0.01 %, 1.31Â±0.09 % and 0.46Â±0.14 %; 94.67Â±0.14 %, 0.65Â±0.03 % and 1.61Â±0.44 % ; 93.76Â±0.09 %, 1.27Â±0.66 %, and 0.69Â±0.51 % respectively. It can be concluded that Chitosan and Aloe vera gel coatings are effective in preservation of cucumbers with significant retention of nutrients and reduction in microbial contamination.

Published: July 2020

Application of machine learning in multiclass classification of brain tumor types has contributed to the development of computer aided diagnosis (CAD) system that can potentially enhance accuracy and speed up diagnosis of the disease. LDA+ELM model with different activation functions were investigated to achieve the optimum performances in terms of accuracy, Kappa statistic, sensitivity, precision, F-measure, training time and test time. We also proposed a user-friendly GUI in characterizing brain tumor types using MR images. First, a total of 3064 slices of CE T1-weighted brain MR images with ground truth were downloaded from a free online database. The manually segmented tumor region was augmented and then undergo several feature extraction techniques. All the feature descriptors obtained were then concatenated, followed by LDA dimensionality approach. Performance of different number of LDA features and ELM activation functions were investigated by repeated training and test. The ELM output of training data for each class was used to fit GMM and these probabilistic models used to estimate posterior probabilities of test data. LDA+ELM model with 5 LDA feature input, utilizing sigmoid function as hidden nodes activation functions achieves the best generalization performance with accuracy of 98.92% and corresponding F-scores for meningioma, glioma and pituitary tumor of 97.81%, 99.1% and 99.5% respectively. The proposed method (LDA+ELM) model performs better compared to other previous works using the same dataset and performing the same classification task.

Published: July 2020

Introduction. Deep-sea fauna of the North Atlantic has a great potential for the development of food industry. Rabbitfish (Chimaera monstrosa) is a hydrobionts that makes up a significant proportion of bycatch in the traditional trawl and longline fishery. The research objective was to determine the technochemical composition and biochemical properties of organs and tissues of rabbitfish.
Study objects and methods. The size-mass and total chemical composition was performed by standard methods. The amino acid composition of proteins was determined by chromatographic separation of amino acid derivatives obtained by reaction with orthophthalic aldehyde and β-mercaptoethanol. The method of one-dimensional thin-layer chromatography made it possible to determine the fractional composition of lipids. The fatty acid composition was determined using an S-180 gas-liquid chromatograph (Yanaco, Japan). The fat-soluble vitamins were determined by the saponification of samples with alkali, extraction, and separation of the unsaponifiable part. The fractional composition of proteins became clear after a planar polyacrylamide gel electrophoresis on (MultiPhor II, Sweden).
Results and discussion. The research featured the size-mass and chemical composition of body parts, the fractional and amino acid composition of proteins, as well as the fractional and fatty acid composition of lipids, vitamins, heavy metals, and organochlorine compounds in the tissues and organs of the rabbitfish. The sensory properties of the samples proved quite high. Hot smoked rabbitfish meat can be recommended for snack foods. Waste (heads, entrails, skin, cartilage, fins) makes up more than 50% of total body weight and can be used in feed production or as a protein-containing raw material for hydrolysates in microbiology, medicine, and food industry.
Conclusion. The research involved a complex biochemical study of the rabbitfish organs and tissues. The performed technochemical studies made it possible to give preliminary recommendations on the directions of its most rational integrated use.

Authors: Urubkov Sergey , Khovanskaya Svetlana , Smirnov Stanislav 
Published: July 2020

Introduction. Diet therapy is one of the main approaches to the treatment of various diseases of the digestive system. A strict lifetime diet is the main method of treatment for gluten intolerance. However, young patients, who are particularly sensitive to dietary restrictions, often fail to follow the diet due to the limited menu of recommended foods and dishes. The diet for children with gluten intolerance should include a sufficient amount of gluten-free grain-based products. They provide children with carbohydrates, dietary fibers, vegetable proteins, fats, B vitamins, and minerals, e.g. potassium, magnesium, selenium, etc. In this regard, it is urgent to develop new types of specialized gluten-free products to expand the diet both in terms of nutritional value and taste diversity.
Study objects and methods. The research is part of a project on the development of dry gluten-free mixes based on buckwheat and amaranth with fruit, vegetable, and berry raw materials. The new formulations are intended for children older than three years of age with gluten intolerance. The research objective was to study the main nutrients in amaranth and buckwheat flours. The study involved the method of infrared spectroscopy using a SpectraStar 2500 analyzer. The data obtained made it possible to calculate the nutritional and energy value of products based on amaranth and buckwheat flours, as well as fruit, vegetable, and berry powders intended for children older than three years of age with gluten intolerance.
Results and discussion. Amaranth flour proved to be rich in protein (13.4%), lipids (5.1%), and ash (2.8%). Native buckwheat flour contained 7.5% of protein, 3.6% of lipids, and 1.4% of ash. The carbohydrate content appeared approximately the same in both samples (56–58%). The dry gluten-free mixes can serve as an important source of vegetable protein (up to 9.44 g per 100 g of the finished product), carbohydrates (up to 40.08 g per 100 g of the finished product, and energy (from 158.12 to 221.85 kcal per 100 g of the finished product).
Conclusion. The high nutritional and biological value of amaranth and buckwheat flours, as well as fruit, vegetable, and berry powders, confirmed the prospect of using them as the main components for functional foods. Amaranth and buckwheat contain no gluten but are rich in protein, amino acids, saturated and unsaturated fatty acids, minerals, and biologically active elements, which makes them an important source of nutrition for children with gluten intolerance.

Published: July 2020

Abstract. Introduction. Domestic food production based on the regional market characteristics can expand the range of functional foods. The research objective was to develop a new technology for desserts based on soy and pumpkin.
Study objects and methods. The research featured soybeans of the “Yurna” variety and pumpkin of the “Nadezhda” variety. Soaked soybeans were mixed with mashed pumpkin and drinking water. The mass was heated and kept at 100°C for 30 min with simultaneous grinding and extraction of soluble dry matter. The soy and pumpkin liquid fraction was separated by filtration. A 2.5% aqueous solution of ascorbic acid was added to the liquid fraction at 75–80°C to coagulate protein and other substances. The soy and pumpkin coagulate had a moisture content of 75.0 ± 1%. It was mixed with sea buckthorn syrup and homogenized. The finished product was called “Nadezhda+”. The “Nezhnyi” dessert consisted of gelling solution mixed with soy and pumpkin coagulate and sea buckthorn syrup, after which the mass was homogenized.
Results and discussion. The expert assessment helped to identify the most significant indicators of the sensory evaluation of the desserts, namely taste and consistency. The sensory evaluation also made it possible to define the optimal homogenization time for the mix: 60 s for “Nadezhda+” and 90 s for “Nezhnyi”. The developed desserts contained protein (5.75 and 4.70 g/100 g), phosphatides (334 and 102 mg/100 g), β-carotene (2.86 and 1.62 mg/100 g), vitamin E (28.60 and 16.00 mg/100 g) and vitamin C (35.10 and 10.60 mg/100 g), respectively.
Conclusion. The content of β-carotene and vitamin E exceeded 15 % of the daily intake in one portion (100 g) of the desserts, as well as vitamin C in “Nadezhda+”. According with State Standard R 52349-2005, the new desserts could be referred to functional foods.

Published: July 2020

Introduction. Cod is of great importance for fishing and fish processing. The main cod-based food products are frozen fish, frozen fillet, and canned cod liver. To increase the degree of processing and reduce the amount of waste, fish producers obtain minced cod from mechanically deboned leftovers of filleting. Minced fish has specific technological parameters, which limits its use in food industry. The research objective was to develop a new commercial technology of minced cod products.
Study objects and methods. The research featured minced Atlantic cod. The fish was processed without thawing to reduce losses from defrosting, microbiological spoilage, and oxidation. The final product was obtained by cutting blocks of frozen minced cod on a cutter and then stabilizing the food mass with vegetable textures and food additives. The methods included selection and determination of the rheological and sensory properties of samples processed on industrial equipment. The optimal formulation was chosen according to the best results of coextruder processing.
Results and discussion. Using a cutter improved the processing quality of the mechanically deboned minced cod. The samples of cold minced cod proved easier to process at a lower temperature of –7°C and below, if compared to the samples of warm minced fish (0°C and above). Adding 15% of a sunflower oil and water emulsion improved the sensory properties of finished products, e.g. fish balls in bread crumbs. Adding 4% of wheat fiber improved the texture of the products, while a higher dose made them dry and crumbly. 20% of crushed soy granules resulted in a rough texture, typical of chopped fish products.
Conclusion. Rheological and organoleptic properties of highly watered mechanically deboned minced cod, as well as the texture of the finished products, could be improved by adding vegetable fillers and emulsions at a low temperature.
