Background: Diabetes is referred to a group of diseases characterized by high glucose levels in blood. It is caused by a deficiency in the production or function of insulin or both, which can occur because of different reasons, resulting in protein and lipid metabolic disorders. The aim of this study was to systematically review the prevalence and incidence of type 1 diabetes in the world. Methods: A systematic search of resources was conducted to investigate the prevalence and incidence of type 1 diabetes in the world. The databases of Medline (via PubMed and Ovid),ProQuest, Scopus, and Web of Science from January 1980 to September 2019 were searched to locate English articles. The located articles were screened in multiple levels of title, abstract,and full-text and final studies that met the inclusion criteria were retrieved and included in the study. Results: From 1202 located articles, 193 studies were included in this systematic review. The results of meta-analysis showed that the incidence of type 1 diabetes was 15 per 100,000 people and the prevalence was 9.5% (95% CI: 0.07 to 0.12) in the world, which was statistically significant. Conclusion: According to the results, the incidence and prevalence of type 1 diabetes are increasing in the world. As a result, insulin will be difficult to access and afford, especially in underdeveloped and developing countries.

Background Considering the lifelong dietary restriction in celiac patients, it is important to assess the diet quality in these patients. Hence, this study aimed to investigate the diet quality in adult celiac patients and compare it with that of the non-celiac people. Methods In the present cross-sectional study, 130 celiac patients were selected from the celiac disease (CD) registry database of East Azerbaijan province, Iran. Non-celiac people (n = 464) was selected from the major lifestyle promotion project conducted in the East Azerbaijan district. The dietary intake data was obtained by an 80-item semi-quantitative food frequency questionnaire. Diet quality was assessed using the healthy eating index-2015 (HEI-2015). Results The mean total HEI score was significantly higher in the celiac group compared with the non-celiac people (P < 0.001) and 68.5% of non-celiac people and 17.4% of celiac patients had poor diet quality. After adjusting for confounding factors, the mean score of total HEI in adherents to gluten-free diet (GFD) was significantly higher compared with non-adherents (P = 0.007). Conclusions Although the mean total HEI score was higher in celiac patients compared with the non-celiac people, about 17.5% of patients had poor diet quality and the scores of whole grains and dairy products group were very low in our population. Accordingly, it seems that educational programs should be held for the celiac patients and non-celiac people to increase their nutritional literacy and enable them to select healthy gluten-free alternatives.

Abstract. Introduction: Cardiovascular disease (CVD) accounts as a major cause of mortality among patients with nonalcoholic fatty liver disease (NAFLD). Resveratrol, a natural polyphenol compound, is known for its antioxidant and antiatherogenic properties and is purported to be beneficial in decreasing CVD risk factors in NAFLD patients. Objectives: This study aimed to investigate the effects of resveratrol on atherogenic risk factors in patients with NAFLD. Methods: This randomized, double-blind, placebo-controlled clinical trial was performed on 50 patients with NAFLD aged 20-60 years. Subjects were randomly assigned to receive a daily dose of 600 mg resveratrol (n = 25) or placebo (n = 25) for 12 wk. Serum liver enzymes, lipid profile and atherogenic indices, blood pressure and anthropometric values were assessed pre and post-treatment. Results: Resveratrol supplementation reduced body weight (from 88.75 ± 11.41 to 87.54 ± 11.18 kg, P = 0.005) and BMI (from 31.00 ± 3.16 to 30.60 ± 3.26 kg/m², P = 0.01) significantly compared to the placebo group. A significant reduction in waist circumference was observed within resveratrol group (from 102.70 ± 7.68 to 101.39 ± 7.62 cm, P = 0.02). There were no significant changes in lipid profile (ox-LDL, ApoA1 and ApoB), serum atherogenic indices (LDL-C/HDL-C, ApoB/ApoA1, ox-LDL/ApoB, LDL-C/ox-LDL and AIP), liver enzymes (AST, ALT, ALP and GGT), hip circumference, waist-to-hip ratio and blood pressure in either group (P > 0.05 for all). Conclusion: These findings indicated that resveratrol supplementation in dose and duration used in this study did not affect most of the CVD risk factors in NAFLD patients. Further studies are warranted to explain more effects of resveratrol on CVD complications of NAFLD. Registration ID in IRCT: IRCT201511233664N16

The successful manufacturing of glulam from several important Australian commercial timbers is quite challenging due to difficulties in gluing. Improvements in adhesive bond performance of spotted gum, Darwin stringybark, and southern pine timber have been achieved using alternative pre-gluing surface machining methods, e.g., face milling and sanding-post planing, when compared to conventional planing methods. In order to improve the understanding of the effects that different surface machining methods have on adhesive bond performance, this study used micro X-ray computed tomography and microscopy to assess key adhesive bond criteria. There was a considerable loss in the amount of adhesive after the wet and dry test cycles for all species. There was also an extremely high frequency of voids in the glue lines for all species, which would negatively impact bond strength and durability. Face mill prepared timber boards resulted in thicker glue lines and greater resistance to adhesion loss, compared to boards prepared via planing. For the two hardwood species, face milling also resulted in greater adhesive penetration; however, for southern pine, there were no significant differences in adhesive penetration between the three surface machining treatments. Adhesive penetration was much deeper in southern pine compared to spotted gum and Darwin stringybark.

Almonds can be classified based on their shell characteristics from soft to hard shell varieties. The majority of Australian and Californian varieties have soft shell properties. Most Spanish almond varieties have hard shells. Although having a hard sealed shell protects the kernel from insect damage it affects their processability. Common commercial almond processing equipment simultaneously compresses and shears the almonds and this creates a high percentage of damaged kernels from the broken shell being forced into the kernel, particularly for hard shell varieties. This paper shows that for the soft shell variety ‘Nonpareil’ and the three hard shell varieties of ‘Marcona’, ‘Tarraco’ and ‘Vyro’ that conditioning by soaking in water and resting before processing improves the recovery of undamaged kernel when shelling using impact. The impacts were applied by feeding the almonds into a rotating impellor and throwing them onto a stationary outer wall. An effective conditioning process resulted in the kernel moisture content increasing from 6% to 14% for hard shell and to 11% for ‘Nonpareil’ varieties. The conditioning process was measured to reduce the amount of scratched, chipped and broken kernel, and hence increased the recovery of undamaged kernel. After shelling, the conditioned kernel needed to be dried back to a 6% moisture content to be suitable for storage. Hence, the industry would be able to increase its recovery of undamaged kernel by changing to an impact shelling process using suitably conditioned almonds.

Background:There is an assumption that sexual health research has great influence on the quality of human life through elevating sexual health standards, and their results will eliminate the burden of sexual health challenges on family relationships. The aim of this study was to review ethical considerations in sexual health research.Materials and Methods:This narrative review was conducted between January 1990 and December 2017 based on the five-step approach of York University. The keywords used to search for the studies included ethical issues, research, sexual health, reproductive health, and sensitive topics. The language of the literatures was English and the search process was performed on PubMed, Elsevier, Ovid, Springer, Google Scholar, ResearchGate, SAGE Publishing, ProQuest, WHO website, Kinsey Confidential, and Worldsexology.Results:After assessing the quality and eligibility of 94 articles, 13 were selected. The results of the present study showed that the most important ethical considerations were protecting the confidentiality and privacy of participants, obtaining informed consent, and paying attention to vulnerable people.Conclusions:The review of literature exhibited several considerations that sexual health researchers are faced with. In order to manage these considerations, the researcher should have sufficient understanding of them. The important matter is that strategies to manage these challenges should be completely rational and practical according to each context. These strategies can also be applied in other societies with great similarities in their context.
