Background and Aims: The purpose of this meta‐analysis was to investigate the effect of vitamin D supplementation on hemoglobin A1C (HbA1C), fasting blood sugar (FBS), low‐density lipoprotein (LDL), high‐density lipoprotein (HDL), systolic blood pressure (SBP), and the total vitamin D level in patients with Type 2 diabetes (T2DM). Methods: A systematic search was conducted in databases such as PubMed (Medline), Scopus, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov using relevant keywords from January 1990 to January 2024. After screening and extracting data, a qualitative evaluation of articles was performed using the Cochrane risk‐of‐bias tool for randomized trials (RoB 2). Results: The findings revealed that vitamin D supplementation significantly decreased the mean HbA1C (SMD: −0.15; 95% CI: −0.29, −0.20; Isquare: 79.76%; p value < 0.001) and mean FBS (SMD: −0.28; 95% CI: −0.40, −0.15; Isquare: 70.13%; p value < 0.001), lowered SBP (SMD: −0.06; 95% CI: −0.16, −0.05; Isquare: 39.63%; p value = 0.23), and reduced LDL (SMD: −0.11; 95% CI: −0.28, −0.05; Isquare: 73.66%; p value < 0.001). Furthermore, vitamin D supplementation increased the average HDL (SMD: 0.13; 95% CI: 0.04, 0.29; Isquare: 79.33%; p value < 0.001) and vitamin D levels (SMD: 1.78; 95% CI: 1.53, 2.04; Isquare: 91.92%; p value < 0.001) in patients with T2DM. Subgroup analyses showed that weight gain, BMI, and duration of the disease could reduce the effect of vitamin D supplementation on diabetes control in affected patients. Conclusion: The results also indicated that taking vitamin D supplements in the amount of 50,000 IU had a significant effect on reducing the indicators related to diabetes control. Based on the combined evidence, the findings of this meta‐analysis suggest that vitamin D supplementation can significantly improve glycemic control and reduce the risk of complications associated with T2DM, especially cardiovascular diseases (CVDs).

The study aimed to compare the effectiveness of a traditional cardiac rehabilitation (CR) program with an enhanced program incorporating the model of therapeutic engagement (MTE) and extended remote support for patients undergoing coronary artery bypass graft (CABG) patients. In a randomized controlled trial, 88 CABG patients were assigned to experimental and control groups. The experimental group received integrated MTE cardiac rehabilitation, and assessments were conducted at three time points: pre-CR, one month later, and three months post-CR. The study measured medication adherence (MARS-5) and sense of coherence (SoC-13) scales. The study found no significant differences in demographic factors between the experimental and control groups. However, significant differences were observed in MARS and individuals' SoC scores over time in the experimental group, with notable improvements (p < 0.001). The control group showed significant changes only up to one month. Group effects were evident, with consistent increases in the experimental group's outcomes at each assessment point. Integrating the MTE into CR programs offers benefits in terms of medication adherence and individuals' sense of coherence, which warrants further investigation and clinical implementation. Cardiac rehabilitation (CR) is recognized as one of the most effective interventions for secondary prevention, but its accessibility is limited in middle-income countries (MICs). This study represents one of the first theoretically-informed CR trials in a MIC that incorporates the model of therapeutic engagement (MTE) combined with extended remote support services into CR program. The MTE model, as a theoretical framework, was highly suitable for CR settings and demonstrated favorable outcomes. This approach has the potential to greatly benefit cardiac patients, particularly those who may initially show hesitance or reluctance towards engaging in CR. [ABSTRACT FROM AUTHOR]

Background and Aims: The primary objective of this systematic review and meta‐analysis was to assess the impact of dextrose prolotherapy on individuals diagnosed with knee osteoarthritis (KOA). Methods: To conduct a thorough investigation, a variety of leading international databases were checked, including PubMed (Medline), Scopus, Web of Sciences, EMBASE (Elsevier), ClinicalTrials.gov, and the Cochrane Library. The search covered a period from January 2000 to the end of June 2023, which facilitated the collection of relevant studies. Results: The findings of the study revealed that when the studies utilizing the Western Ontario McMaster Universities Index tool (WOMAC) were combined, patients with KOA who received prolotherapy experienced an improvement in function compared with those who received other treatments (SMD: 0.20; 95% Confidence Interval [1]: −0.11, 0.51; p value SMD = 0.221; I2: 78.49%; pheterogeneity < 0.001). Additionally, there was a decrease in mean pain and stiffness among patients who received prolotherapy compared with those who received other treatments or a placebo [(SMD: −0.95; 95% CI: ‐1.14, −0.76; p value SMD < 0.001; I2: 59.35%; pheterogeneity = 0.070) and (SMD: −0.21; 95% CI: −0.32, −0.10; p value SMD < 0.001; I2: 88.11%; pheterogeneity < 0.001)]. Furthermore, based on the Visual Analog Scale (VAS) score, there was a reduction of 0.81 units out of 10 in mean pain for patients with KOA who received prolotherapy (SMD: −0.81; 95% CI: −5.63, 4.10; p value SMD = 0.693; I2: 48.54%; pheterogeneity = 0.08). Conclusion: Drawing from the data analysis performed in this meta‐analysis, it is apparent that dextrose prolotherapy exhibits promising effectiveness in reducing joint pain and stiffness, as well as improving functional performance in individuals suffering from KOA. Furthermore, it is recommended that forthcoming studies incorporate follow‐up periods to guide decisions concerning the duration of prolotherapy's effects. [ABSTRACT FROM AUTHOR]

Background: Forward Head Posture (FHP), which refers to the head being more forward than the shoulder, is one of the most common postural defects of all ages. Therefore, in this study, we aimed to compare the effectiveness of exercise therapy and electroacupuncture in patients with FHP and myofascial pain syndrome (MPS)., Methods: The present study was an open-label randomized clinical trial. A total of 61 patients with FHP and MPS who were referred to the physical medicine clinic of Besat Hospital between 2020 and 2021 were analyzed. Patients in one group were treated with electroacupuncture, and another one was treated with exercise therapy. The primary outcomes were FHP angles (CVA, CA, and shoulder angle), pain intensity (VAS), and quality of life (SF-12). Paired t-test was used to compare the results obtained in the pre-test and post-test. To detect differences over time, the analysis of variance models was used to repeat the observations. If the p-test result is less than the test significance level of 0.05, the null hypothesis is not confirmed., Results: The rate of final CVA and increase in CVA in the exercise therapy group were significantly higher than in the electroacupuncture group ( P < 0.001). The average shoulder angle in the exercise therapy group increased from 47.1° ± 3.0° to 51.9° ± 3.3° ( P < 0.001) and in the electroacupuncture group from 47.9° ± 3.1° to 51.0° ± 2.8° ( P < 0.001). A significant difference was observed between the two groups in terms of pain intensity changes during the study., Conclusion: Overall, the results of this study showed that both exercise therapy and electroacupuncture significantly improved patients' posture, reduced pain intensity, and increased quality of life in FHP patients with MPS; But exercise therapy was more effective in improving FHP angles and electroacupuncture was more successful in reducing patients' pain intensity., Competing Interests: The authors declare that they have no competing interests., (© 2023 Iran University of Medical Sciences.)
