Several studies have assessed the effects of milk and dairy product intake on sleep quality and duration. Such investigations have varied in terms of their geographic locations, amounts of milk and dairy products, study participants (age, sex, race), and study designs. The present study aimed to summarize this literature and provide a unified view on whether the intake of milk and dairy products affects sleep quality. This systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The following keywords were chosen as electronic database search items from MeSH (medical subject headings) terms and descriptors in health sciences (DeHS) lists: milk, yogurt, dairy product, cheese, sleep, human, observational study, and interventional study. As a result, a total of 14 studies published between 1972 and 2019 were included in this review, including eight randomized controlled trials, two experimental studies with cross-over designs, one longitudinal study, and three cross-sectional studies. Four studies targeted older adults, three included toddlers, two targeted children, and six enrolled adults inclusive of university students. Overall, these studies indicated that a well-balanced diet that includes milk and dairy products is effective in improving sleep quality, despite mixed results across studies attributable to differences in study populations and methods.

The aim of this review was to determine the relationship between dairy product consumption and arterial stiffness, measured by pulse wave velocity (PWV). We systematically searched the Medline, Embase and Web of Science databases until 30th January 2019 for cross-sectional data from studies addressing the association between dairy product consumption and PWV. This study was registered with PROSPERO (CRD42018110528). Both the inverse-variance fixed effects method and the DerSimonian and Laird method were used to compute pooled estimates of effect size (ES) and the respective 95% confidence intervals (CIs). Seven studies were included in the meta-analysis, with a total of 16,443 patients. Total dairy product (ES = −0.03; 95% CI [−0.04, −0.01]) and cheese (ES = −0.04; 95% CI [−0.07, −0.01]) consumption were weak, but significantly associated with lower PWV levels. Conversely, milk intake showed no significant association with PWV (ES = 0.02; 95% CI [−0.01, 0.05]). Heterogeneity in the ES was not important for the three groups of dairy products assessed. This systematic review and meta-analysis of seven studies found no detrimental effects of dairy product consumption on arterial stiffness measured by PWV. Due to the scarcity of studies, further investigations are warranted to clarify the role of dairy products on arterial stiffness.

Abstract Objectives The consumption of milk and dairy products makes an important contribution to children's nutrient intake, yet due to relatively high saturated fat content, the health benefits of dairy products have come under question and public health advice is often perceived as unclear. This review aimed to provide an overview of the current available evidence taken from systematic reviews and meta-analyses on dairy product consumption and risk of obesity, type 2 diabetes (T2D) and cardiovascular disease (CVD) in children, adolescents, and adults. Methods The literature of English-language systematic reviews and meta-analyses published up to September 2019 was reviewed by searching the following three databases: ISI Web of Science, PubMed, and Google Scholar. Search terms included ‘dairy’, ‘milk’, ‘yogurt’, ‘obesity’, ‘adiposity’, ‘bodyweight’, ‘type 2 diabetes’, ‘cardiovascular diseases’, ‘coronary heart disease’, ‘blood pressure’, ‘insulin resistance’, ‘glucose’, ‘children’, ‘adolescents’, ‘adults’ and combinations of these. Published work on calcium supplementation was excluded. Results Milk and certain dairy products were found to be not associated with or inversely associated with obesity in children and adolescents. In adults, consumption of milk and dairy products improves body composition and enhances weight loss during energy restriction diets, while it has a neutral effect on body weight in maintenance diets. Prospective cohort studies suggest that the consumption of dairy products, with regular or low-fat content, does not adversely affect the risk of T2D or CVD outcomes and may have a protective effect. The plausible mechanisms underlying the effect of dairy nutrients on obesity and cardiometabolic disease are incompletely understood but may include effects on lipolysis, lipogenesis and fatty acid absorption. Conclusions Dairy product consumption, as part of a balanced diet, may protect against the risk of obesity, T2D, and CVD. However, further research is needed to better understand the role of different types of dairy products and of different fat content in obesity, T2D, and CVD. The new and emerging range of products (including plant-based alternatives) being used as dairy milk substitutes has yet to be evaluated in scientific studies. Funding Sources None.

Milk and dairy products constitute an important source of energy and nutrients for humans. Food preferences may significantly influence the actual consumption (and thus nutrition) of people at the population level. The objective of the present large-scale survey was to specify current preferences for milk and dairy products with regard to age and sex. The study was conducted across the Moravia region, Czech Republic, on a sample of 451 individuals divided into 4 age groups: children, adolescents, young adults, and elderly people. A graphic scale questionnaire was administered, with respondents rating their degree of preference for each food item by drawing a mark on a 35 mm line. Out of the 115 items in the questionnaire, 11 items represented dairy products. Data was analysed by means of a general linear model using IBM SPSS Statistics software. Preference for milk was lower in the elderly group than the other groups (P < 0.01). In children, the most preferred dairy product was cream, which was in contrast with the elderly group. Significant sex differences were only found with low-fat yoghurt (P < 0.01). The overall preference for dairy products (21.6) was lower than the average preference for all foods on the list (22.5). The cross-sectional study revealed intergenerational differences in preferences for specific dairy products, which were most marked in case of cream, processed cheese, blue cheese, and buttermilk. The knowledge of these differences might help promote more focused action at the community level directed at increasing the overall consumption of dairy products in the population.

Sexual activity during adolescence can lead to unwanted pregnancy, which in turn can result in serious maternal and fetal complications. The present study aimed to evaluate the complications related to adolescent pregnancy, through a systematic review using the Medical Subject Headings: “pregnancy complication” AND “adolescent” OR “pregnancy in adolescence”. Only full original articles in English or Portuguese with a clearly described methodology, were included. No qualitative studies, reviews or meta-analyses, editorials, case series, or case reports were included. The sample consisted of 15 articles; in that 10 were cross-sectional and 5 were cohort studies. The overall prevalence of adolescent pregnancy was 10%, and among the Brazilian studies, the adolescent pregnancy rate was 26%. The cesarean delivery rate was lower than that reported in the general population. The main maternal and neonatal complications were hypertensive disorders of pregnancy, prematurity and low birth weight, respectively. Adolescent pregnancy is related to increased frequency of neonatal and maternal complications and lower prevalence of cesarean delivery.

Educational gamification consists of the use of game elements and game design techniques in the educational context. The objective of this study is to examine the existing evidence on the impact of educational gamification on student motivation and academic performance in the last five years in order to analyze its distribution over time, educational level, variables, and most used game elements, and know the advantages of its implementation in the classroom. For this, a systematic review is proposed through the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) methodology in three multidisciplinary databases, through an exhaustive search with inclusion and exclusion criteria on quantitative experimental studies that explore gamification in educational centers, which provide information about the most current lines of research. Fourteen studies were included in this review. These used experimental or quasi-experimental designs. Most of them report gamification as a valid learning strategy. The results support the conclusion that educational gamification has a potential impact on the academic performance, commitment, and motivation of students. Therefore, this study implies the need to expand research on the needs and challenges of students when learning with gamified techniques.

AbstractInjectable fillers represent one of the most requested minimally invasive treatments to rejuvenate the aging face, and its popularity is steadily rising. A vast majority of filler treatments are with hyaluronic acid (HA). The aim of this systematic review is to evaluate patient outcomes, safety profile, and administration techniques of various HA fillers for malar augmentation. A systematic review of the published literature was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included PubMed, Embase, and Science Direct databases. Medical Subject Headings (MeSH) terms used were “cheek” OR “midface” OR “malar” and “filler” OR “hyaluronic acid” OR “Juvederm” OR “Restylane” OR “Perlane” OR “Belotero.” The initial search identified 699 articles; 256 duplicates were removed. Additional 12 studies were identified from reference lists. A total of 455 were screened by title and abstract and 387 studies were eliminated based on criteria. Also, 68 articles underwent full-text review, and 18 articles were included in the final review and involved seven different HA formulations. Men and women from many age groups were highly satisfied with their results following HA treatment for midface augmentation up to 24 months. The most common adverse events included bruising, swelling, and tenderness, and typically lasted no more than 2 weeks. Upper cheek filler injections near the zygoma should be placed in the submuscular plane while lower cheek injections should be placed in the subcutaneous tissue. HA is an attractive choice for midface augmentation due to its high patient satisfaction, long-lasting effects, and low side-effect profile. Due to the variability in technique, level of expertise, and subjective measurements across studies, one optimal regimen could not be concluded. However, midface augmentation treatment should be personalized to each patient. Additional clinical trials are required to more conclusively determine the most appropriate approach for this procedure.

Aim. To conduct a systematic review and meta-analysis according to the following PICO question: in extracted human permanent teeth, does preflaring, compared with unflared canals, influence the accuracy of WL determination with EAL? Material and Methods. A systematic review was conducted according to the PRISMA checklist, using the following databases: PubMed, Science Direct, Scopus, and Web of Science. Studies related to WL determination using EAL both in preflared and unflared root canals of extracted human teeth were included. The outcome of interest was the accuracy of the electronic WL determination. A quality assessment of the included studies was performed, determining the risk of bias. The meta-analyses were calculated with the 5.4 RevMan software using the inverse variance method with random effects. PROSPERO registration: CRD42021243412. Results. Ten experimental studies fulfilled the inclusion criteria, and most of them found that preflaring increases the accuracy of the EALs in WL determination. The calculated OR was 1.98 (95% CI = 1.65–2.37; p < 0.00001; I2 = 10%), indicating that the determination of WL by EALs is almost twice as accurate in preflared canals. The accuracy of Root ZX in WL determination increases more than three times (OR = 3.25; p < 0.00001). Preflaring with Protaper files significantly increases the accuracy of EALs (OR = 1.76; p < 0.00001). The total risk of bias of the included studies was low. No obvious publication bias was observed. Conclusions. The results indicate a significant increase in the accuracy of WL determination with EAL after preflaring, doubling the percentage of exact measurements. Preflaring should be recommended as an important step during mechanical enlargement of the root canal, not only because it improves the access of the files to the canal, but also because it allows one to obtain more accurate electronic determinations of WL.

BACKGROUND: Plantago major is a medicinal plant that has been used for centuries to treat various health conditions including wounds. PURPOSE: To investigate the effectiveness of the topical use of P major in healing skin wounds in animal models. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review was conducted. Seven (7) electronic databases (Virtual Health Library, Public/Publisher MEDLINE, Scopus, Web of Science, Embase, Cumulative Index of Nursing and Allied Health Literature, and CAB Direct) were searched for controlled studies published in English from January 2006 to March 2020. The Collaborative Approach to Meta Analysis and Review of Animal Data from Experimental Studies tools guided the evaluation of the studies and determined their quality. The Systematic Review Center for Laboratory Animal Experimentation was used to assess the risk of bias. RESULTS: Of the 176 publications identified, 4 met the inclusion criteria. Studies included 20 to 100 animals and varying concentrations of P major. There were no reports of losses during research. Wound healing was assessed between 17 and 21 days following wounding. The best response in terms of wound contraction rate occurred with 10%, 20%, and 50% concentrations when compared with control groups. One (1) study did not have an animal ethics committee review. All studies had a high risk of bias and a lack of methodological rigor. CONCLUSION: The results of this review did not find evidence about the in vivo effectiveness of P major for wound healing. More rigorous preclinical studies with adequate sample sizes are required to identify the best concentrations and formulations as well as increase understanding about the mechanisms of action of P major in wound healing.

Современный рынок молочной продукции претерпевает существенные изменения, в основе которых лежит тенденция на удешевление продукции. Российские молочные продукты, произведенные из классического сырья по традиционным технологиям, зачастую подвергаются фальсификации продуктами с пониженными массовыми долями жира и белка, заменой молочных компонентов и живых заквасочных культур вследствие отсутствия системы идентификационных характеристик. Реформой технического регулирования, проведенной в Российской Федерации в 2000 году, правила идентификации как способ отнесения продукта к определенной группе продукции посредством сопоставления его характеристик с установленными были законодательно закреплены на федеральном уровне. В настоящее время идентификация служит неотъемлемой частью оценки (подтверждения) соответствия продукции и является главным средством борьбы с фальсификацией. Критериями идентификации выступают регламентированные показатели продукта. Технический регламент Таможенного союза 033/2013 «О безопасности молока и молочной продукции» включает понятие «национальный молочный продукт», однако критерии идентификации этой группы продукции отсутствуют. Целью исследования был поиск уникальных характеристик российских молочных продуктов для их идентификации среди аналогичной продукции. В качестве метода был применен ретроспективный анализ литературы с глубиной поиска до 1930-х гг. Установлено, что в качестве критериев идентификации молочных продуктов использовали не только сырьевой и технологический признаки, но и упаковку. Выявленные критерии будут положены в основу формирования системы идентификации российских молочных продуктов. The modern dairy market is undergoing significant changes, which are based on the trend towards cheaper products. Russian dairy products made from classical raw materials using traditional technologies are often falsified by products with reduced mass fractions of fat and protein, replacing dairy components and live starter cultures due to the lack of an identification system. The reform of technical regulation carried out in the Russian Federation in 2000, the identification rules as a way of classifying a product as a specific product group by comparing the characteristics with the established ones were legally fixed at the federal level. Currently, identification is an integral part of the assessment (confirmation) of product conformity and is the main means of combating falsification. Identification criteria are regulated product indicators. The technical regulation of the Customs Union 033/2013 «On the safety of milk and dairy products” includes such a concept as «national dairy product», however, there are no criteria for identifying this group of products. The aim of the research was to search for unique characteristics of Russian dairy products and classical technologies that distinguish them from similar products. As a method, a retrospective analysis of the literature with a search depth of up to the 1930s was used. It was established that not only raw and technological characteristics, but also packaging were used as criteria for identifying dairy products. The identified criteria will be the basis for the formation of an identification system for Russian dairy products.

Background: Schizophrenia (SZ) is a severe psychiatric disorder typically characterized by multidimensional psychotic syndromes. Electroconvulsive therapy (ECT) is a treatment option for medication-resistant patients with SZ or to resolve acute symptoms. Although the efficacy of ECT has been demonstrated in clinical use, its therapeutic mechanisms in the brain remain elusive. Objective: This study aimed to summarize brain changes on structural magnetic resonance imaging (sMRI) and functional MRI (fMRI) after ECT. Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review was carried out. The PubMed and Medline databases were systematically searched using the following medical subject headings (MeSH): (electroconvulsive therapy OR ECT) AND (schizophrenia) AND (MRI OR fMRI OR DTI OR DWI). Results: This review yielded 12 MRI studies, including 4 with sMRI, 5 with fMRI and 3 with multimodal MRI. Increases in volumes of the hippocampus and its adjacent regions (parahippocampal gyrus and amygdala) as well as insula and frontotemporal regions were noted after ECT. fMRI studies found ECT-induced changes in different brain regions/networks, including the hippocampus, amygdala, default model network, salience network and other regions/networks that are thought to highly correlate with the pathophysiologic characteristics of SZ. The results of the correlation between brain changes and symptom remissions are inconsistent Conclusion: Our review provides evidence supporting ECT-induced brain changes on sMRI and fMRI in SZ and explores the relationship between these changes and symptom remission.
