High-density lipoprotein (HDL) functional traits have emerged as relevant elements that may explain HDL antiatherogenic capacity better than HDL cholesterol levels. These properties have been improved in several lifestyle intervention trials. The aim of this systematic review is to summarize the results of such trials of the most commonly used dietary modifications (fatty acids, cholesterol, antioxidants, alcohol, and calorie restriction) and physical activity. Articles were screened from the Medline database until March 2021, and 118 randomized controlled trials were selected. Results from HDL functions and associated functional components were extracted, including cholesterol efflux capacity, cholesteryl ester transfer protein, lecithin-cholesterol acyltransferase, HDL antioxidant capacity, HDL oxidation status, paraoxonase-1 activity, HDL anti-inflammatory and endothelial protection capacity, HDL-associated phospholipase A2, HDL-associated serum amyloid A, and HDL-alpha-1-antitrypsin. In mainly short-term clinical trials, the consumption of monounsaturated and polyunsaturated fatty acids (particularly omega-3 in fish), and dietary antioxidants showed benefits to HDL functionality, especially in subjects with cardiovascular risk factors. In this regard, antioxidant-rich dietary patterns were able to improve HDL function in both healthy individuals and subjects at high cardiovascular risk. In addition, in randomized trial assays performed mainly in healthy individuals, reverse cholesterol transport with ethanol in moderate quantities enhanced HDL function. Nevertheless, the evidence summarized was of unclear quality and short-term nature and presented heterogeneity in lifestyle modifications, trial designs, and biochemical techniques for the assessment of HDL functions. Such findings should therefore be interpreted with caution. Large-scale, long-term, randomized, controlled trials in different populations and individuals with diverse pathologies are warranted.

Abstract Context Cardiovascular disease is a major public health problem and represents a significant burden of disease globally. Lifestyle interventions have their limitations and an intervention that will effectively address cardiovascular risk factors to help reduce this growing burden of disease is required. Objective Carnosine and other histidine-containing dipeptides (HCDs) have exerted positive effects on cardiovascular risk factors and diseases in animal and human studies. The authors conducted a systematic review and meta-analysis examining the effects of HCDs on cardiovascular outcomes in line with the PRISMA guidelines. Data Sources The Medline, Medline in process, Embase, Cumulative Index of Nursing and Allied Health, and All EBM databases were searched from inception until January 25, 2019, for randomized controlled trials (RCTs) examining the effects of HCDs on cardiovascular outcomes, compared with placebo or controls. Data Extraction Basic characteristics of the study and populations, interventions, and study results were extracted. The grading of recommendations assessment, development, and evaluation approach was used to assess the quality of evidence for each outcome. Data Analysis A total of 21 studies were included. Of these, 18 were pooled for meta-analysis (n = 913). In low risk of bias studies, HCD-supplemented groups had lower total cholesterol (n = 6 RCTs; n = 401; weighted mean difference [WMD], −0.32 mmol/L [95%CI, −0.57 to −0.07], P = 0.01) and triglyceride levels (n = 6 RCTs; n = 401; WMD, −0.14 mmol/L [95%CI, −0.20 to −0.08], P < 0.001) compared with controls. In studies using carnosine, triglycerides levels were also lower in the intervention group vs controls (n = 5 RCTS; n = 309; P < 0.001). There were no significant differences in blood pressure, heart rate, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C) or the total cholesterol to HDL-C ratio between groups. Conclusions Carnosine and other HCDs may have a role in improving lipid profiles. Larger studies with sufficient follow-up are necessary to confirm these findings and explore the use of HCDs in the prevention of cardiovascular diseases.

The optimal method of fixation for primary total hip replacements (THR), particularly fixation with or without the use of cement is still controversial. In a systematic review and metaanalysis of all randomized controlled trials comparing cemented versus uncemented THRS available in the published literature, we found that there is no significant difference between cemented and uncemented THRs in terms of implant survival as measured by the revision rate. Better short-term clinical outcome, particularly an improved pain score can be obtained with cemented fixation. However, the results are unclear for the long-term clinical and functional outcome between the two groups. No difference was evident in the mortality and the post operative complication rate. On the other hand, the radiographic findings were variable and do not seem to correlate with clinical findings as differences in the surgical technique and prosthesis design might be associated with the incidence of osteolysis. We concluded in our review that cemented THR is similar if not superior to uncemented THR, and provides better short term clinical outcomes. Further research, improved methodology and longer follow up are necessary to better define specific subgroups of patients in whom the relative benefits of cemented and uncemented implant fixation can be clearly demonstrated.

Objective: The benefits of Pilates for blood glucose and lipids remain unclear. The purpose of this study was to examine the effect of Pilates on their levels.Methods: Searches were conducted in five databases to identify relevant articles published until October 29, 2020. Paired reviewers independently screened the articles and extracted data from each included study. Meta-analysis was performed to assess the effects of Pilates on blood glucose and lipids. Subgroup analyses and sensitivity analyses were conducted to explore heterogeneity.Results: According to the inclusion and exclusion criteria, 15 randomized controlled trials (RCTs) comprising 587 participants were included in the study. Overall, the Pilates group (PG) had a significantly greater reduction in post-prandial blood glucose than the control group (CG) (MD = −22.25 mg/dL, 95% CI: [−28.34, 16.17] mg/dL, P < 0.00001, I2 = 0%); glycated hemoglobin (HbA1c) (MD = −0.78%, 95% CI: [−1.13, −0.42]%, P < 0.0001, I2 = 88%); total cholesterol (TC) (MD = −20.90 mg/dL, 95% CI: [−37.21, −4.60] mg/dL, P = 0.01, I2 = 84%); triglycerides (TG) (MD = −12.59 mg/dL, 95% CI: [−19.88, −5.29] mg/dL, P = 0.0007, I2 = 86%); and low density lipoprotein cholesterol (LDL-C) (MD = −12.39 mg/dL, 95% CI: [−16.82, −7.95] mg/dL, P < 0.00001, I2 = 45%) compared to CG, whereas no significant difference was detected between the two groups in fasting blood glucose (MD = −7.04 mg/dL, 95% CI: [−17.26, 3.17] mg/dL, P = 0.18, I2 = 93%), insulin (MD = −1.44 μU/mL, 95% CI: [−4.30, 1.41] μU/mL, P = 0.32, I2 = 0%); and high density lipoprotein cholesterol (HDL-C) (MD = −2.68 mg/dL, 95% CI: [−9.03, 3.67] mg/dL, P = 0.41, I2 = 89%). However, by subgroup analysis, we found that compared to the CG, PG showed no significant improvement in blood glucose and lipids levels for non-diabetics, while it presented a significantly greater decrease in post-prandial blood glucose, TC, TG, and LDL-C for diabetic patients. Notably, for diabetic patients, Pilates and medication treatments showed no significant reduction in fasting blood glucose (MD = −7.00 mg/dL, 95% CI: [−26.06, 12.06] mg/dL, P = 0.40) and HbA1c (MD = −0.23%, 95% CI: [−0.58, 0.13]%, P = 0.21, I2 = 0%) than medications treatment used alone, and Pilates combined with medications and dietary treatments presented no significant improvement in fasting blood glucose than a combination of medications and dietary treatments (MD = −10.90 mg/dL, 95% CI: [−32.35, 10.54] mg/dL, P = 0.32, I2 = 94%).Conclusions: Overall, Pilates could improve post-prandial blood glucose, fasting blood glucose, HbA1c, TG, TC, and LDL-C for diabetic patients, which could be influenced by its duration and intensity. Moreover, it had no significant effect on blood glucose and lipids for non-diabetic individuals. However, Pilates, as an adjunctive treatment to medications was not superior to medications used alone in lowering fasting blood glucose and HbA1c. Furthermore, Pilates combined with medications and dietary treatments showed no significant improvement in fasting blood glucose, whereas it had a greater reduction in post-prandial blood glucose and HbA1c for diabetic patients.Systematic Review Registration:https://osf.io/xgv6w.

Abstract Objective Lumbar radiculopathy is a pain syndrome caused by compression/irritation of the lumbar nerve root(s). Traction is a well-known and commonly used conservative treatment for lumbar radiculopathy, although its effectiveness is disputed. The purpose of this systematic review and meta-analysis of randomized controlled trials was to evaluate the effects of different types of traction added to or compared with conservative treatments on pain and disability. Methods Data were obtained from CENTRAL, PUBMED, CINAHL, Scopus, ISI Web of Science, and PEDro from their inception to April 2020. All randomized controlled trials on adults with lumbar radiculopathy, using mechanical traction, without any restriction regarding publication time or language, were considered. Two reviewers selected the studies, evaluated the quality assessment, and extracted the results. Meta-analysis used a random-effects model. Eight studies met the inclusion criteria, and 5 were meta-analyzed. Results Meta-analyses of results from low-quality studies indicated that supine mechanical traction added to physical therapist treatments had significant effects on pain (g = −0.58 [95% CI = −0.87 to −0.29]) and disability (g = −0.78 [95% CI = −1.45 to −0.11]). Analyses of results from high-quality studies of prone mechanical traction added to physical therapist intervention for pain and disability were not significant. These results were also evident at short-term follow-up (up to 3 months after intervention). Conclusions The literature suggests that, for pain and disability in lumbar radiculopathy, there is short-term effectiveness of supine mechanical traction when added to physical therapist intervention. Impact This systematic review may be relevant for clinical practice due to its external validity because the treatments and the outcome measures are very similar to those commonly used in a clinical context.
