ABSTRACT One of hypothetical mechanisms related to cognition is exercise-induced IGF-1. Objective: The aim of this study was to analyze the effects of exercise on IGF-1 levels and cognition in the elderly. Methods: The article searches were conducted on Pubmed, Web of Science, PsycINFO and Scielo databases and reviewed according to PRISMA guidelines. The inclusion criteria were: [1] original articles published up to 2017; [2] samples including elderly; [3] protocols including physical exercise; [4] longitudinal studies having exercise as main outcome; [5] assessment of IGF-1; [6] cognition assessment. Results: Seven studies were included in this review. Three of the studies showed an exercise-induced increase in IGF-1; three found stable IGF-1 levels and one found a reduction in IGF-1; with and without improvement in cognition. Conclusion: Disparities in the type of physical exercise, protocols and samples under different conditions hinder the establishment of a consensus on IGF-1, cognition and physical exercise.

Osteoporosis is the most common reason for a broken bone among the elderly. Several experimental studies have been reported that Nigella sativa(NS) and/or its major component thymoquinone (TQ) have good effects on osteoporosis and bone healing. We conducted this systematic review toevaluate these relevant studies to prove whether NS and/or TQ has potential effect on osteoporosis and can stop pathogenesis of this disease or thismatter still just a fiction. A search on published studies was done using databases including Scopus, PubMed, Google Scholar, Web of Science, andCINAHIL. Terms searched included “Nigella sativa, black seed, TQ, osteoporosis, bone healing.” Initially, 213 articles were extracted. After reviewing their titles and abstracts, 124 articles (Medline, 43; Scopus, 67; EBSCO, 14) were retrieved for further evaluation. However, after excluding the clinical trial studies, human reviews, removal of abstracts and unrelated studies, seven studies were considered finally as eligible for our review. Finally, seven studies were considered eligible for our review. The total number of animals used was 220 (150 rats and 70 rabbits) from different experimental study. Based on the results of this systematic review, we conclude that NS or TQ extract therapy for osteoporosis cannot be recommended yet and these data will not suffice to exclude the beneficial effects of NS on bone turnover reliably. Therefore, more studies are required to explore the specific cellular and molecular targets of NS or TQ using animal osteoporosis models. Once the anti-osteoporotic effectiveness of NS or TQ will be established, human studies can be carried out.Keywords: Nigella sativa, Black seed, Thymoquinone, Osteoporosis, Bone healing.

The Relationship

Food intake has been shown to be related to several environmental factors including the presence of music. However, previous findings of the relationship between music and food intake are inconsistent. In the present study, a systematic review and meta-analysis was conducted to quantitatively review the extent to which music is associated with food intake as well as to investigate potential moderators that might have contributed to the heterogeneity of the existing findings. Literature was searched on four databases (i.e., PsycINFO, Web of Science, PubMed, and ProQuest Dissertations and Theses) and Google Scholar. Nine articles published from 1989 to 2020 met our inclusion criteria. A meta-analysis was carried out via a three-level random-effects model. The overall effect size (i.e., Hedges’ g) was 0.19 (95% Confidence Interval: −0.003, 0.386; SE = 0.10, t = 1.99, p = 0.054), indicating a marginally significant but small effect size. Body Mass Index (F(1, 21) = 5.11, p = 0.035) was found to significantly contribute to the heterogeneity of effect sizes, with larger positive effects of music on food intake for individuals with higher BMI. However, music-related features did not significantly moderate the relationship between music and food intake. More experimental studies are needed to update the current meta-analysis and get a better understanding of this topic.

Introduction: The objective of this systematic review is to assess the effect of vibrational force on biomarkers for orthodontic tooth movement. Methods: An electronic search was conducted for relevant studies (up to December 31, 2020) on the following databases: Pubmed, Google scholar, Web of Science, Cochrane Library, Wiley Library, and ProQuest Dissertation Abstracts and Thesis database. Hand searching of selected orthodontic journals was also undertaken. The selected studies were assessed for the risk of bias in Cochrane collaboration risk of bias tool. The “traffic plot” and “weighted plot” risk of bias distribution are designed in the RoB 2 tool. The 2 authors extracted the data and analyzed it. Results: Six studies fulfilled the inclusion criteria. The risks of biases were high for 4, low and some concern for other 2 studies. The biomarkers, medium, device, frequency and duration of device, as well as other data were extracted. The outcomes of the studies were found to be heterogenous. Conclusion: One study showed highly statistically significant levels of IL-1 beta with <.001. Rate of tooth movement was correlated with levels of released biomarkers under the influence of vibrational force in 3 studies, but it was found to be significant only in 1 study. It was further observed that vibration does not have any significant reduction in pain and discomfort.

The Relationship

Cognitive functions are essential in any form of exercise. Recently, interest has mounted in addressing the relationship between caffeine intake and cognitive performance during sports practice. This review examines this relationship through a structured search of the databases Medline/PubMed and Web of Science for relevant articles published in English from August 1999 to March 2020. The study followed PRISMA guidelines. Inclusion criteria were defined according to the PICOS model. The identified records reported on randomized cross-over studies in which caffeine intake (as drinks, capsules, energy bars, or gum) was compared to an identical placebo situation. There were no filters on participants’ training level, gender, or age. For the systematic review, 13 studies examining the impacts of caffeine on objective measures of cognitive performance or self-reported cognitive performance were selected. Five of these studies were also subjected to meta-analysis. After pooling data in the meta-analysis, the significant impacts of caffeine only emerged on attention, accuracy, and speed. The results of the 13 studies, nevertheless, suggest that the intake of a low/moderate dose of caffeine before and/or during exercise can improve self-reported energy, mood, and cognitive functions, such as attention; it may also improve simple reaction time, choice reaction time, memory, or fatigue, however, this may depend on the research protocols.

Abstract To date, there is no quantitative review examining the influence of heart rate variability biofeedback (HRV BFB) on the athlete population. Such an undertaking may provide valuable information on the autonomic and respiration responses of athletes when performing HRV BFB. Thus, purpose of this preliminary systematic review and meta-analysis on the effects of HRV BFB on HRV and respiration of athletes. Searches of Springerlink, SportDiscus, Web of Science, PROQUEST Academic Research Library, Google Scholar, and ScienceDirect were conducted for studies that met the following criteria: (1) experimental studies involving athletes that underwent randomized control trial; (2) availability of HRV BFB as a treatment compared with a control (CON)/placebo (PLA); (3) any pre and post HRV variable and/or breathing frequency as dependent variable/s; and, (4) peer-reviewed articles written in English. Four out of 660 studies involving 115 athletes (25 females and 90 males) ages 16–30 years old were assessed in this review. Preliminary findings suggest the promising ability of HRV BFB to improve respiratory mechanics in athlete population. More work is needed to determine the autonomic modulatory effect of HRV BFB in athletes.

Abstract Background Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths in Africa. In Africa, the major causes of HCC include chronic infection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV). Knowledge of the changes in the incidence of viral hepatitis-associated HCC over time and the factors responsible for such changes is key in informing policies for the prevention of viral hepatitis-associated HCC in Africa. Aim The study aimed to systematically summarize the changes in the prevalence of viral hepatitis among HCC patients and the overall effect of the prevalence of viral hepatitis on the incidence of HCC over the past four decades in Africa (1980–2019). Methods A literature search was conducted in MEDLINE (PubMed), Google Scholar, Science Direct, Scopus, Web of Science, and African wide web for articles published on viral hepatitis-associated HCC in Africa from 1980 to 2019. The abstracts of the articles were screened for eligibility and those meeting the inclusion criteria were retrieved and reviewed. Results A total of 272 studies were included in the analysis. Viral hepatitis-related HCC incidence changed by 1.17% (95% confidence interval (CI): 0.63–1.71, p < 0.001), 0.82% (95% CI: 0.45–1.18, p < 0.001), and 3.34% (95% CI: 2.44–4.25, p < 0.001) for every 1% change in the prevalence of HBV, HCV, and hepatitis D virus (HDV) respectively, per decade. The incidence of HBV-related HCC decreased by − 0.50% (95% CI: − 0.74 – − 0.25, p < 0.001) over the last 40 years, while HCV-related HCC increased. Conclusion Overall, the incidence of viral hepatitis-associated HCC has not declined, mainly due to no decline in the prevalence of HCV, HDV, and the high number of chronic hepatitis B carriers on the African continent. There is an urgent need for the allocation of resources for the implementation of treatment and preventive programs for HBV, HCV, HDV, and HCC in Africa. This systematic review is registered with PROSPERO®, number CRD42020169723.

This study aimed to perform a systematic review and meta-analysis of the glycemic index (GI) of gluten-free bread (GFB) and its main ingredients. The systematic review followed PRISMA guidelines, using seven electronic databases (PubMed, EMBASE, Scopus, Science Direct, Web of Science, gray literature research with Google Scholar, and patents with Google Patent tool), from inception to November 2020. Eighteen studies met the inclusion criteria evaluating 132 GFB samples. Five articles tested GI in vivo, eleven in vitro; and two studies tested both methods. The analysis showed that 60.7% (95% CI: 40.2–78.1%) of the samples presented high glycemic indexes, evidencing a high glycemic profile for GFB. Only 18.2% (95% CI: 11.7–27.2%) of the bread samples presented in the studies were classified as a low GI. Meta-analysis presented moderate/low heterogenicity between studies (I2 = 61% and <1% for both high and low GIs) and reinforced the proportion of high GIs. Lower GIs were found in formulations based on Colocasia esculenta flour or enriched with fiber, yogurt and curd cheese, sourdough, psyllium, hydrocolloids, enzymes, fructans, and resistant starch, highlighting the efficacy of these ingredients to lower GFBs’ GI. GFB tends to present high GI, impacting the development of chronic diseases when consumed.

PURPOSE: To systematically review studies that used questionnaires for the evaluation of restriction on auditory participation in adults and the elderly.RESEARCH STRATEGY: Studies from the last five years were selected through a bibliographic collection of data in national and international journals in the following electronic databases: ISI Web of Science and Virtual Health Library - BIREME, which includes the LILACS and MEDLINE databases.SELECTION CRITERIA: Studies available fully; published in Portuguese, English, or Spanish; whose participants were adults and/or the elderly and that used questionnaires for the evaluation of restriction on auditory participation.DATA ANALYSIS: Initially, the studies were selected based on the reading of titles and abstracts. Then, the articles were fully and the information was included in the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist.RESULTS: Three-hundred seventy studies were found in the researched databases; 14 of these studies were excluded because they were found in more than one database. The titles and abstracts of 356 articles were analyzed; 40 of them were selected for full reading, of which 26 articles were finally selected. In the present review, nine instruments were found for the evaluation of restriction on auditory participation.CONCLUSION: The most used questionnaires for the assessment of the restriction on auditory participation were the Hearing Handicap Inventory for the Elderly (HHIE), Hearing Handicap Inventory for Adults (HHIA), and Hearing Handicap Inventory for the Elderly - Screening (HHIE-S). The use of restriction on auditory participation questionnaires can assist in validating decisions in audiology practices and be useful in the fitting of hearing aids and results of aural rehabilitation.
