Studies assessed the beneficial effects of aerobic exercise on blood pressure (BP); however, few studies have evaluated the effects of long-term resistance training on variations of this response. The aim of the study was to verify through a systematic review, the long-term effect of resistance training on BP. Searches were made on Medline through Pubmed, Science Direct, Scopus, Web of Science and Lilacs databases. Overall, 751 articles were found, of which 22 were further analyzed. The analysis followed the PRISMA checklist (Statement for Reporting Systematic Reviews and Meta-Analyses of Studies) and was divided according to two resistance training models: traditional resistance training (TRT), resistance training alone; or combined resistance training (CRT), resistance training associated with aerobic exercise. Greater BP reductions occurred for CRT compared to TRT. However, further studies are needed to better explicit the resistance training variables (number of exercises, repetitions, number of sets, intervals, speed of execution and load intensity), in order to identify the best training model and improve the methodological quality of experiments in an attempt to reduce the risk of bias.

Abstract The objective of the present study was to determine the effectiveness of the regular practice of traditional resistance training (RT) on systolic (SBP) and diastolic blood pressure (DBP) in normotensive elderly persons. A systematic review of randomized clinical trials and meta-analyses was performed. Searches were performed without language restrictions in different databases. Randomized clinical trials published from 1966 to 2010 that assessed the effects of traditional RT on resting blood pressure (BP) and/or for the treatment of high BP were included. Only studies that assessed the effects of traditional RT on elderly adults, regardless of the number of exercises, with the presence of a control group and comparisons between groups, were included. Twenty-nine studies were found, but only six met the inclusion criteria. The mean difference was used for meta-analysis, using a 95% confidence interval and a random effect model. Traditional RT induced a significant decrease in SBP (-6.63 mmHg; p=0.02) but not in DBP (-3.34 mmHg; p=0.11). These results suggest that traditional RT may be a non-pharmacological strategy for the control of BP in the elderly.

The benefit of exercise in inducing brain-derived neurotrophic factor (BDNF) functions in relation to cognition had been reported. Nevertheless, the ambiguity remains with regards to the types of exercise and the duration of exercise required for one to have beneficial effects. In this study, we aimed to analyse the effects of varying modes of exercises and the duration required to improve BDNF functions, specifically in the young adults. The types of exercises evaluated in the meta-analysis include (1) single bout of acute aerobic exercise, (2) repeated and frequent sessions of aerobic exercise (program exercise) over a course of several weeks, and (3) resistance training. Only a single bout of acute aerobic exercise (z=4.92, p=0.00001) is sufficient to cause an increase in BDNF following exercise intervention, while program exercise (z=1.02, p=0.31) and resistance training (z=0.92, p=0.36) demonstrated inconsistencies, some exhibited significant increase in BDNF levels while others exhibited similar results with the control groups.

Vitamin D takes part into the metabolism of the bone tissue, regulating the processes of mineralization and remodeling. There are a lot of data on uses of using of vitamin D in patients of trauma and orthopedic profile, but opinions about the method of taking, dosage, effectiveness differ greatly and requires more in-depth research.The objectiveof this study was to review and analyze of actual clinical and experimental researches related to the influence of metabolites of vitamin D in the endoprosthesis of large joints, among the available sources of medical database of PubMed, Cohraine, e-Library.The results of most studies of local and systemic use of metabolites of vitamin D led to the conclusion about the beneficial effects of these compounds on bone regeneration in traumatology and orthopedics. However, further researches are required to clearly identify the clinical application of these approaches.We supposed that the following factors considered for long-term work: assessment of long-term effect and usage of standardized doses, learning new derivatives of vitamin D, synergy in the combinations of vitamin D preparations, pharmacokinetics of vitamin D preparations and polymorphisms of genes associated with vitamin D, genes influencing the life activity of bone and assessment of the effect of concomitant disease, systemic pathological processes on related of vitamin D metabolism, and bone restoration. We are also define the simultaneous corrections of vitamin D levels as an important component of the compensation of bone disorders in trauma and orthopedic patients.

Previous studies from our laboratory have demonstrated that chronic diabetes in rats results in cardiomyopathy, associated with sympathetic nervous system (SNS) hyperactivity. On the other hand, it is well known that the beneficial cardiovascular effects of exercise training in diabetes are due in part to normalization of the sympathetic outflow and improvement in the responsiveness of the myocardium to autonomic stimulation. Recently, resistance training (RT) has been recognized as a useful therapeutic tool for the treatment of chronic diseases and similar to aerobic exercise, has been reported to improve metabolic profile and body composition. Therefore, the aim of this study was to evaluate the effect of moderate-intensity RT on circulating and cardiac catecholamines concentration, to understand whether this type of exercise is also associated with cardiovascular protection. Wistar rats (3 months old) were randomized into: control (C), diabetic (D), diabetic + RPT (DR) and diabetic + APT (DA). Animals were made diabetic with a single tail injection of streptozotocin (STZ, 50 mg/Kg). Resistance exercise training was performed on a vertical ladder (5 days/week, 8 weeks) at 40-60% maximal load, and moderate aerobic training was performed on a treadmill (5 days/week, 8 weeks). Diabetes significantly increased plasma concentration of adrenaline (D: 5.3 ± 1.0 vs. C: 4.1 ± 0.6 ng/mL) and noradrenaline (D: 14.5 ± 0.2 vs. C: 3.1± 0.8 ng/mL), and both exercise modalities induced a significant reduction of them: adrenaline (DR: 1.1 ± 0.3; DA: 0.7 ± 0.16 vs. D: 5.3 ± 1.0 ng/mL) and noradrenaline (DR: 1.0 ± 0.2; DA: 0.7 ± 0.1 vs. D: 14.5 ± 0.2 ng/mL). Cardiac concentration of noradrenaline was also increased in diabetic group (D: 62 ± 7 vs. CS: 34 ± 6 pg/g) and only aerobic exercise was capable to reduce its concentration in heart tissue (DA: 30 ± 6 vs. D: 62 ± 7; DR: 55 ± 7 pg/g). The results from the present study show for the first time additional beneficial effects of RT on modulating SNS activity in diabetes. Moreover, considering that RT does not modulate cardiac catecholaminergic secretion, it also highlights the importance of aerobic training in diabetes treatment.

Erp System

ERP can be called as one of the most significant contributions of computer science and particularly information systems for the business environment which can support all complicated business process of an organisation including sale, purchase, warehouse and manufacturing into a single database. For such complex system like ERP, implementation involves much collaboration which raises the concern of the success of the project. Among most significant success and failure factors of ERP implementation cited in the literature are training and consultation. For many years the majority of ERP vendors promote their product specific training models as long-term and expensive allowing the organisation to gain knowledge of the ERP system and the way it handles the business process. However, recent studies showed that ERP training can be conducted in the short term and with minimum investment and yet to be effective. Findings triggered a signal and opened a new door for research to investigate vendor-independent training models that require limited investment in training and consultancy. This paper aims to provide an overview of the literature; highlighting the research methods and theories used by authors towards building ERP training models and methods.

Introduction Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, and it is characterized by episodes of vertigo roundabout when the head is moved. A systematic review was performed using the most important scientific databases. This review included studies published in English in the last ten years, performed in adults, with emphasis on the diagnosis and treatment of BPPV. Objective To investigate the long-term effectiveness of vestibular rehabilitation (VR) in patients with BPPV and the rate of recurrence of symptoms. Data Synthesis A total of 38 studies were identified, of which only 12 met the inclusion criteria. The majority of the studies stated that VR is effective in decreasing the symptoms, with a short-term efficacy of 84.7%, and 89.2% in the long term in the reviewed studies. Conclusion Valuable studies show the beneficial effects of the maneuvers for the treatment of BPPV and their long-term effectiveness. This strengthens the conclusion that this treatment is effective in resolving symptoms and decreasing recurrences.

Cognitive symptoms are a core feature of schizophrenia and are related to an unfavorable disease outcome. So far, there are no satisfactory pharmacological approaches to address cognitive symptoms. For some time now, aerobic exercise has been demonstrated in various trials to be a promising candidate for this indication. The aim of this brief qualitative review was to present the most recent meta-analyses regarding the capacity of exercise to improve cognition in schizophrenia patients. Additionally, we give a short overview of the effects in other conditions, like healthy subjects and patients with major depression. We conducted a focused literature search using the PubMed database, concentrating on meta-analyses which are based on a systematic search. The most recent meta-analysis investigating the efficacy of aerobic exercise on cognitive impairments in schizophrenia patients provides evidence that exercise has positive effects on cognitive functioning in this population. However, the effect seems not to be specific; there were positive findings regarding healthy subjects and patients with depressive disorders as well, even if they were less consistent. As most available trials have a small to modest sample size and have no consensus with regard to the intervention regime, nor to the assessment of cognition, the findings are difficult to generalize. In the future, standardized clinical trials focusing on the long-term effects of exercise are needed to evaluate whether the improvements in cognition are sustainable.

Clinical studies and meta-analyses have supported the notion that consuming cinnamon spice long term can have beneficial effects in individuals with normal glucose homeostasis and varying degrees of glucose intolerance including type 2 diabetes. The objective of this study was to evaluate the acute effect of cinnamon on the post-prandial responses to a typical American breakfast in normal and overweight/obese participants (ClinicalTrials.gov registration No. NCT04686552). The consumption of a single dose of 6 g of cinnamon added to oatmeal prepared with milk resulted in a significant reduction of one of our primary outcomes post-prandial insulin response (niAUC0−180min) in overweight/obese participants compared to control consuming breakfast without cinnamon. We also performed exploratory analysis of secondary outcomes. In normal weight participants, we observed a decrease of post-prandial glucagon response (niAUC0−180min and glucagon levels at 60–120 min) and C-peptide response (30 min) comparing breakfast with to without cinnamon. Cinnamon consumption did not change post-prandial glycemic response in normal weight participants, but increased 60 min post-prandial glucose in overweight/obese participants compared to control. In summary, cinnamon consumption differentially affected post-prandial hormonal responses in normal and overweight/obese participants.
