Background: The shortage and disproportionate distribution of health care workers worldwide is further aggravated by the inadequacy of training programs, difficulties in implementing conventional curricula, deficiencies in learning infrastructure, or a lack of essential equipment. Offline digital education has the potential to improve the quality of health professions education.Objective: The primary objective of this systematic review was to evaluate the effectiveness of offline digital education compared with various controls in improving learners’ knowledge, skills, attitudes, satisfaction, and patient-related outcomes. The secondary objectives were (1) to assess the cost-effectiveness of the interventions and (2) to assess adverse effects of the interventions on patients and learners.Methods: We searched 7 electronic databases and 2 trial registries for randomized controlled trials published between January 1990 and August 2017. We used Cochrane systematic review methods.Results: A total of 27 trials involving 4618 individuals were included in this systematic review. Meta-analyses found that compared with no intervention, offline digital education (CD-ROM) may increase knowledge in nurses (standardized mean difference [SMD]=1.88; 95% CI 1.14 to 2.62; participants=300; studies=3; I2=80%; low certainty evidence). A meta-analysis of 2 studies found that compared with no intervention, the effects of offline digital education (computer-assisted training [CAT]) on nurses and physical therapists’ knowledge were uncertain (SMD 0.55; 95% CI –0.39 to 1.50; participants=64; I2=71%; very low certainty evidence). A meta-analysis of 2 studies found that compared with traditional learning, a PowerPoint presentation may improve the knowledge of patient care personnel and pharmacists (SMD 0.76; 95% CI 0.29 to 1.23; participants=167; I2=54%; low certainty evidence). A meta-analysis of 4 studies found that compared with traditional training, the effects of computer-assisted training on skills in community (mental health) therapists, nurses, and pharmacists were uncertain (SMD 0.45; 95% CI –0.35 to 1.25; participants=229; I2=88%; very low certainty evidence). A meta-analysis of 4 studies found that compared with traditional training, offline digital education may have little effect or no difference on satisfaction scores in nurses and mental health therapists (SMD –0.07; 95% CI –0.42 to 0.28, participants=232; I2=41%; low certainty evidence). A total of 2 studies found that offline digital education may have little or no effect on patient-centered outcomes when compared with blended learning. For skills and attitudes, the results were mixed and inconclusive. None of the studies reported adverse or unintended effects of the interventions. Only 1 study reported costs of interventions. The risk of bias was predominantly unclear and the certainty of the evidence ranged from low to very low.Conclusions: There is some evidence to support the effectiveness of offline digital education in improving learners’ knowledge and insufficient quality and quantity evidence for the other outcomes. Future high-quality studies are needed to increase generalizability and inform use of this modality of education.

Despite growing evidence of the significant influence of blood-flow-restricted (BFR) training on different body functions, its impact on the vascular system, especially the arteries, is controversial. Therefore, the objective of our study was to analyze how BFR exercise, compared to other types of exercise without the restriction of blood flow, influences arterial functions and angiogenesis in adults. Studies comparing the effect of BFR versus non-BFR training on arterial parameters were divided into three categories: endothelial function, angiogenesis, and other vasculature functions. The search was based on Cochrane Library, PubMed^®, and Embase, and 38 studies were included. The meta-analysis revealed a more significant improvement in flow-mediated dilatation (FMD) (p = 0.002) and the production of the primary angiogenesis biomarker vascular endothelial growth factor (VEGF) (p = 0.009) after BFR compared to non-BFR training (p = 0.002). The analysis of the pulse wave velocity, ankle-brachial index, systolic blood pressure, and heart rate did not show significant differences in changes between BFR and non-BFR training. The other parameters examined did not have sufficient data to be included in the meta-analysis. The results obtained present trends that suggest significant impacts of BFR training on endothelial functions and angiogenesis. There is still a lack of multicenter randomized clinical trials including many participants, and such studies are necessary to confirm the advantage of BFR over non-BFR activity.

Objective. The aim of the study was to evaluate the effectiveness of pulmonary rehabilitation with music therapy in patients with asthma. Methods. Seventy-six selected inpatients (54 women and 22 men; mean age = 56.4 years; SD = 11.8) with stable asthma underwent pulmonary rehabilitation in two groups: standard versus music therapy. Results. After the intervention, an increase in analyzed spirometric values (forced expiratory volume at the first second (FEV₁), FEV₁ as a percentage of vital capacity (FEV₁ % FVC), forced expiratory flow at 25%, 50%, and 75% of vital capacity (FEF₂₅, FEF₅₀, and FEF₇₅, respectively), and peak expiratory flow) was observed in both the groups (p < .05) but without any intergroup differences (p > .05). A greater increase of mean FEV₁ % FVC, FEF₅₀, and FEF₇₅ values was observed only in the patients with mild asthma from the music therapy group (p < .05). In both the groups, a dyspnea reduction was noted (p < .001). However, it was influenced neither by the type of rehabilitation nor by the gender (p > .05), but the interaction of these variables was significant (p = .044). A dyspnea reduction was observed in women in both the groups (p < .001) and in men in the music therapy group only (p = .001). A change in the value of anxiety (6.43, SD = 7.73) on the 10th day compared with the first day of the study was noticed (p < .001). However, this change was not influenced by the type of rehabilitation, gender, or a combination of these two variables (p > .05). Conclusion. Music therapy improves the respiratory function in patients with mild asthma and reduces dyspnea mainly in men with asthma.

Blood-flow-restricted exercise (BFRE) has been gaining constantly increasing interest in rehabilitation, but its influence on endothelial functions has not been well studied yet. Our aim is to examine the influence of low-resistance BFRE on endothelial functions and angiogenesis. This prospective cross-over study involved 35 young healthy adults. They conducted a 21-min low-resistant exercise with blood flow restricted by pressure cuffs placed on arms and tights. They also did the same training but without blood flow restriction. Endothelial parameters and angiogenesis biomarkers were evaluated before and up to 20 min after exercise. Both types of exercise increased Flow-Mediated Dilatation (FMD) but elevation after BFRE was more significant compared to the controls. The stiffness index decreased only after BFRE, while the reflection index decreased significantly after both types of exercise but was higher after BFRE. Platelet endothelial cell adhesion molecule (PECAM-1) and vascular endothelial growth factor receptor 2 (VEGFR-2) concentrations were increased by both exercise types but elevations were higher after BFRE compared to the controls. Only BFRE elevated the mean serum CD34 protein concentration. Based on these results, we can assume that low-resistance BFR exercise stimulates angiogenesis and improves endothelial functions more significantly compared to the same training performed without blood flow restriction.

The comorbidity of peripheral arterial disease (PAD) and chronic obstructive pulmonary disease (COPD) is obvious from a clinical point of view, especially as smoking is an important risk factor for both. Another factor connecting these two clinical conditions is chronic inflammation, which plays a crucial role in their pathophysiology. The aim of this study was to present the prevalence of COPD in patients with PAD, as well as the prevalence of PAD in COPD patients confirmed in all patients by two reliable methods: spirometry and ankle-brachial index (ABI), respectively. The MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews were searched to identify the potentially eligible publications from the previous 10 years. The published characteristics of different PAD and COPD populations were analyzed. A database search identified 894 records. Reliable criteria of both COPD and PAD diagnosis were used only in seven publications. The prevalence of PAD among patients with COPD ranged from 8.5 to 81.4%. The severity of the disease and the exclusion of nonsmokers or symptomatic patients from the analyses were important factors affecting this parameter. The prevalence of COPD in patients with PAD was measured reliably only in one study and assessed as 27.2%. The comorbidity of COPD and PAD is a relatively common occurrence. There are very few publications addressing this issue based on reliable diagnostic criteria, especially in the field of PAD. In the case of COPD and PAD patients, spirometry and ABI measurements are worth considering as noninvasive screening tests for COPD and PAD, respectively.
