Meta-Analysis
BACKGROUND
Mineralocorticoid receptor blockade could be a potential approach for the inhibition of chronic kidney disease (CKD) progression. The benefits and harms of different mineralocorticoid receptor antagonists (MRAs) in CKD are inconsistent.
OBJECTIVES
The aim of the study was to summarize the benefits and harms of MRAs for CKD patients.
METHODS
We searched MEDLINE, EMBASE, and the Cochrane databases for trials assessing the effects of MRAs on non-dialysis-dependent CKD populations. Treatment and adverse effects were summarized using meta-analysis.
RESULTS
Fifty-three trials with 6 different MRAs involving 22,792 participants were included. Compared with the control group, MRAs reduced urinary albumin-to-creatinine ratio (weighted mean difference [WMD], -90.90 mg/g, 95% CI, -140.17 to -41.64 mg/g), 24-h urinary protein excretion (WMD, -0.20 g, 95% CI, -0.28 to -0.12 g), estimated glomerular filtration rate (eGFR) (WMD, -1.99 mL/min/1.73 m2, 95% CI, -3.28 to -0.70 mL/min/1.73 m2), chronic renal failure events (RR, 0.86, 95% CI, 0.79-0.93), and cardiovascular events (RR, 0.84, 95% CI, 0.77-0.92). MRAs increased the incidence of hyperkalemia (RR, 2.04, 95% CI, 1.73-2.40) and hypotension (RR, 1.80, 95% CI, 1.41-2.31). MRAs reduced the incidence of peripheral edema (RR, 0.65, 95% CI, 0.56-0.75) but not the risk of acute kidney injury (RR, 0.94, 95% CI, 0.79-1.13). Nonsteroidal MRAs (RR, 0.66, 95% CI, 0.57-0.75) but not steroidal MRAs (RR, 0.20, 95% CI, 0.02-1.68) significantly reduced the risk of peripheral edema. Steroidal MRAs (RR, 5.68, 95% CI, 1.26-25.67) but not nonsteroidal MRAs (RR, 0.52, 95% CI, 0.22-1.22) increased the risk of breast disorders.
CONCLUSIONS
In the CKD patients, MRAs, particularly in combination with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, reduced albuminuria/proteinuria, eGFR, and the incidence of chronic renal failure, cardiovascular and peripheral edema events, whereas increasing the incidence of hyperkalemia and hypotension, without the augment of acute kidney injury events. Nonsteroidal MRAs were superior in the reduction of more albuminuria with fewer peripheral edema events and without the augment of breast disorder events.

Review
Fibrin, derived from proteins involved in blood clotting (fibrinogen and thrombin), is a biopolymer with different applications in the health area since it has hemostasis, biocompatible and three-dimensional physical structure properties, and can be used as scaffolds in tissue regeneration or drug delivery system for cells and/or growth factors. Fibrin alone or together with other biomaterials, has been indicated for use as a biological support to promote the regeneration of stem cells, bone, peripheral nerves, and other injured tissues. In its diversity of forms of application and constitution, there are platelet-rich fibrin (PRF), Leukocyte- and platelet-rich fibrin (L-PRF), fibrin glue or fibrin sealant, and hydrogels. In order to increase fibrin properties, adjuvant therapies can be combined to favor tissue repair, such as photobiomodulation (PBM), by low-level laser therapy (LLLT) or LEDs (Light Emitting Diode). Therefore, this systematic review aimed to evaluate the relationship between PBM and the use of fibrin compounds, referring to the results of previous studies published in PubMed/MEDLINE, Scopus and Web of Science databases. The descriptors "fibrin AND low-level laser therapy" and "fibrin AND photobiomodulation" were used, without restriction on publication time. The bibliographic search found 44 articles in PubMed/MEDLINE, of which 26 were excluded due to duplicity or being outside the eligibility criteria. We also found 40 articles in Web of Science and selected 1 article, 152 articles in Scopus and no article selected, totaling 19 articles for qualitative analysis. The fibrin type most used in combination with PBM was fibrin sealant, mainly heterologous, followed by PRF or L-PRF. In PBM, the gallium-aluminum-arsenide (GaAlAs) laser prevailed, with a wavelength of 830 nm, followed by 810 nm. Among the preclinical studies, the most researched association of fibrin and PBM was the use of fibrin sealants in bone or nerve injuries; in clinical studies, the association of PBM with medication-related treatments osteonecrosis of the jaw (MRONJ). Therefore, there is scientific evidence of the contribution of PBM on fibrin composites, constituting a supporting therapy that acts by stimulating cell activity, angiogenesis, osteoblast activation, axonal growth, anti-inflammatory and anti-edema action, increased collagen synthesis and its maturation, as well as biomolecules.

BMC Pharmacology & Toxicology Oct 2017Vildagliptin and pioglitazone/rosiglitazone are emerging Oral Hypoglycemic Agents (OHAs) which are used to treat patients suffering from Type 2 Diabetes Mellitus (T2DM).... (Meta-Analysis)
Meta-Analysis Review
Adverse drug effects observed with vildagliptin versus pioglitazone or rosiglitazone in the treatment of patients with type 2 diabetes mellitus: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Vildagliptin and pioglitazone/rosiglitazone are emerging Oral Hypoglycemic Agents (OHAs) which are used to treat patients suffering from Type 2 Diabetes Mellitus (T2DM). In this analysis, we aimed to systematically compare the adverse drug events which were observed with the use of vildagliptin versus pioglitazone or rosiglitazone respectively.
METHODS
Online databases were searched for studies comparing vildagliptin with pioglitazone/rosiglitazone. Adverse drug events were considered as the clinical endpoints in this analysis. We calculated Odds Ratios (OR) with 95% Confidence Intervals (CIs) using the RevMan 5.3 software. All the authors had full access to the data which were used and approved the final version of the manuscript.
RESULTS
A total number of 2396 patients were analyzed (1486 and 910 patients were treated with vildagliptin and pioglitazone/rosiglitazone respectively). Vildagliptin and pioglitazone/rosiglitazone were both associated with similar overall adverse drug events (OR: 1.00, 95% CI: 0.81-1.24; P = 1.00). Headache (OR: 0.88, 95% CI: 0.60-1.27; P = 0.49) and upper respiratory tract infection (OR: 0.95, 95% CI: 0.71-1.27; P = 0.75) were similarly observed. However, dizziness was significantly lower with pioglitazone/rosiglitazone (OR: 0.63, 95% CI: 0.43-0.92; P = 0.02). Back pain, diarrhea and nausea were insignificantly lower with pioglitazone/rosiglitazone (OR: 0.81, 95% CI: 0.49-1.33; P = 0.40), (OR: 0.83, 95% CI: 0.48-1.44; P = 0.52) and (OR: 0.52, 95% CI: 0.25-1.05; P = 0.07) respectively, whereas peripheral edema and weight gain were insignificantly higher (OR: 1.21, 95% CI: 0.56-2.62; P = 0.63) and (OR: 2.29, 95% CI: 0.51-10.34; P = 0.28) respectively. Nevertheless, when pioglitazone and rosiglitazone were separately compared with vildagliptin, peripheral edema and weight gain were significantly higher with rosiglitazone (OR: 2.36, 95% CI: 1.40-3.99; P = 0.001) and (OR: 5.20, 95% CI: 2.47-10.92; P = 0.0001) respectively.
CONCLUSION
Both vildagliptin and pioglitazone/rosiglitazone are acceptable for the treatment of patients with T2DM on the basis that they are not significantly different in terms of overall adverse drug events. However, weight gain and peripheral edema would have to be re-assessed in further larger randomized controlled trials.

Review
BACKGROUND
In recent years subintimal angioplasty (SIA) has become an established percutaneous procedure for the treatment of symptomatic lower limb arterial chronic total occlusions. However, the clinical benefits of this practice remain unclear. The aim of the review was to determine the effectiveness of SIA on clinical outcomes. This is an update of a review first published in 2013.
OBJECTIVES
To assess the effectiveness of SIA versus other treatment for people with lower limb arterial chronic total occlusions, determined by the effects on clinical improvement, technical success rate, patency rate, limb salvage rate, and morbidity rates.
SEARCH METHODS
The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register (last searched January 2016) and Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 12). We also searched clinical trials registries.
SELECTION CRITERIA
We included data from randomized controlled trials comparing the effectiveness of SIA and any other management method in the treatment of lower limb arterial chronic total occlusions. The primary intervention of interest was SIA, with or without a stent, for the restoration of vessel patency in people with occlusions of a lower limb artery. We compared SIA against alternative modalities used to restore vessel patency, including conventional percutaneous transluminal angioplasty, surgical bypass, or any other treatments. We compared different SIA devices and techniques against each other.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected trials, assessed trials for eligibility and methodological quality, and extracted data. The third review author resolved disagreements.
MAIN RESULTS
Two studies, involving a total of 147 participants with TransAtlantic Inter-Society Consensus (TASC)-II D femoropopliteal lesions, met our inclusion criteria and were included in the review. Both studies were small but otherwise of high methodological quality. However, the treatment techniques and control groups of the two studies differed, precluding the combining of study results and resulting in the evidence being less applicable. We therefore considered the quality of the evidence to be low.In one study, participants with TASC-II D lesions were randomized to receive either SIA with stenting of the superficial femoral artery or remote endarterectomy (RE) with stenting of the superficial femoral artery. Three-year follow-up results showed a Rutherford classification improvement of 64% in the SIA group compared to 80% in the RE group (risk ratio (RR) 0.79, 95% confidence interval (CI) 0.61 to 1.03; 95 participants; P = 0.079). Postexercise ankle brachial index improvements (defined as an increased value of 0.2) were reported in 70% of participants in the SIA group compared to 82% in the RE group (RR 0.86, 95% CI 0.68 to 1.08; 95 participants; P = 0.18). The study reported the technical success rate was 93% for the SIA group and 96% for the RE group (RR 0.97, 95% CI 0.88 to 1.07; 95 participants; P = 0.91). Primary patency at 12 months was 59.1% in the SIA group compared to 78.4% in the RE group (RR 0.75, 95% CI 0.57 to 1.00; 95 participants; P = 0.05). Primary patency at 24 months was 56.8% in the SIA group compared to 76.5% in the RE group (RR 0.74, 95% CI 0.55 to 1.00; 95 participants; P = 0.05) and 47.7% in the SIA group and 62.7% in the RE group at 36 months (RR 0.76, 95% CI 0.52 to 1.11; 95 participants; P = 0.15). Assisted primary patency was 52.3% in the SIA group compared to 70.6% in the RE group (P = 0.01) at 36 months. Secondary patency was better for the RE group (P = 0.03) at 36 months. Limb salvage at three years' follow-up was 95% in the SIA group and 98% in the RE group (RR 0.97, 95% CI 0.90 to 1.05; 95 participants; P = 0.4). There were no perioperative deaths, but complications occurred in two SIA participants (femoral pseudoaneurysm and pulmonary edema) and in three RE participants (seroma, femoral pseudoaneurysm, superficial femoral artery acute occlusion).In the second study, the effects of the SIA OUTBACK re-entry catheter device in people affected by TASC-II D superficial femoral artery chronic total occlusion were compared with the SIA manual re-entry technique. This study did not report clinical improvement and limb salvage. Technical success was achieved in all cases in both the OUTBACK device and manual groups. The primary 6-month patency rate was 100% in the OUTBACK group (26 of 26 participants) compared to 96.2% in the manual group (25 of 26 participants) (RR 1.04, 95% CI 0.94 to 1.15). The primary 12-month patency rate was 92.3% in the OUTBACK group (24 of 26 participants) compared to 84.6% in the manual group (22 of 26 participants) (RR 1.09, 95% CI 0.90 to 1.33). Patency rates at 24 and 36 months were not reported. The study reported that there were no complications.
AUTHORS' CONCLUSIONS
Using the GRADE approach, we classified the quality of the evidence presented by both studies in this review as low due to small study size and the small number of studies. In addition, the two included trials differed from each other in the techniques and control used, and we were therefore unable to combine the data. Consequently there is currently insufficient evidence to support SIA over other techniques. Evidence from more randomized controlled trials is needed to assess the role of SIA in people with chronic lower limb arterial total occlusions.

Review
Health Education Programmes to Improve Foot Self-Care Knowledge and Behaviour among Older People with End-Stage Kidney Disease (ESKD) Receiving Haemodialysis (A Systematic Review).
BACKGROUND
ESKD is a total or near-permanent failure in renal function. It is irreversible, progressive and ultimately fatal without peritoneal dialysis (PD), haemodialysis (HD) or kidney transplantation. Dialysis treatments can create new and additional problems for patients, one of which is foot amputation, as a result of non-healing wounds and vascular complications. The association between dialysis therapy and foot ulceration is linked to several factors: physical and psychological health; peripheral arterial disease (PAD); mobility; tissue oxygenation; manual dexterity; neuropathy; visual acuity; anaemia; nutrition; leg oedema; hypoalbuminemia; infection; inadequacy of dialysis; and leg/foot support during dialysis. The potential risk factors for foot ulceration may include: not routinely receiving foot care education; incorrect use of footwear; diabetes duration; neuropathy; and peripheral arterial disease.
AIM
The aim of this review is to examine the factors that help or hinder successful implementation of foot care education programmes for ESKD patients receiving haemodialysis.
METHOD
A comprehensive literature search was completed using five electronic databases. Medline; CINAHL; Embase; PsycINFO; and Cochrane Library. The Joanna Briggs Institute checklist (JBI) was used to quality appraise full text papers included in the review. The systematic review was not limited to specific categories of interventions to enable optimal comparison between interventions and provide a comprehensive overview of the evidence in this important field of foot care.
RESULTS
We found no previously published studies that considered foot care education programmes for haemodialysis patients who are not diabetic; thus, the present systematic review examined four studies on diabetic patients receiving haemodialysis exposed to foot care education programmes from various types of intervention designs.
CONCLUSIONS
This systematic review has provided evidence that it is possible to influence foot care knowledge and self-care behaviours in both diabetic patients receiving haemodialysis and healthcare professionals.

Review
Patients with heart failure are subjected to a substantial burden related to fluid overload symptoms. Exercise can help the lymphatic system function more effectively to prevent fluid build-up in tissues and interstitium, thus potentially mitigating the symptoms due to fluid overload. The objective of this systematic review was to examine the effects of exercise-based interventions on fluid overload symptoms among patients with heart failure. MEDLINE, Embase, Cochrane Library, and CINAHL databases were systematically searched for relevant studies published from inception to August 2021. We included randomized controlled trials that compared exercise-based interventions of different modalities and usual medical care for adult patients with heart failure and reported the effects of interventions on any symptoms related to fluid overload. A random-effects meta-analysis was used to estimate the effectiveness, and a subgroup analysis and univariate meta-regression analysis were used to explore heterogeneity. Seventeen studies covering 1086 participants were included. We found robust evidence indicating the positive effect of exercises in dyspnea relief (SMD = -0.48; 95%CI [-0.76, -0.19]; = 0.001); the intervention length also influenced the treatment effect (β = 0.033; 95%CI [0.003, 0.063]; = 0.04). Initial evidence from existing limited research showed that exercise-based intervention had positive effect to alleviate edema, yet more studies are needed to verify the effect. In contrast, the exercise-based interventions did not improve fatigue compared with usual care (SMD = -0.27; 95%CI [-0.61, 0.06]; = 0.11). Findings regarding the effects of exercises on bodily pain, gastro-intestinal symptoms, and peripheral circulatory symptoms were inconclusive due to limited available studies. In conclusion, exercise-based interventions can be considered as an effective nonpharmacological therapy for patients with heart failure to promote lymph flow and manage fluid overload symptoms. Exercise-based interventions seem to have very limited effect on fatigue. More research should investigate the mechanism of fatigue related to heart failure. Future studies with high methodological quality and comprehensive assessment of symptoms and objective measure of fluid overload are warranted.

PURPOSE
Immune checkpoint inhibitors have developed rapidly and have demonstrated antitumor activity in various cancers. To evaluate the safety and efficacy of atezolizumab in treating cancers, we conducted this meta-analysis.
METHODS
Embase, PubMed, MEDLINE, the Central Register of Controlled Trials of the Cochrane Library, and the American Society of Clinical Oncology database were searched for relevant studies. The primary outcomes were any grade adverse events (AEs) and grade ≥3 AEs. The secondary outcomes were overall objective response rate, pooled 6-month progression-free survival (PFS) rate, 1-year overall survival (OS) rate, median PFS, and median OS.
RESULTS
Our meta-analysis was based on 14 clinical trials with 3,266 patients. The total risk of any grade AEs reached 69%, while grade ≥3 AEs happened in only 13% of participants. The overall atezolizumab-related death rate was 0.17%. Major common AEs involved fatigue (24.5%), decreased appetite (13.2%), nausea (12.3%), diarrhea (10.8%), pyrexia (10.7%), pruritus (9.6%), cough (9.5%), edema peripheral (8.6%), and rash (8.4%). The most common severe AEs were fatigue (2.2%), anemia (1.9%), and dyspnea (1.9%). Meanwhile, we found that 6% patients reached complete response and 16% partial response. The pooled 6-month PFS rate and 1-year OS rate were 0.36 (95% CI: 0.31-0.41) and 0.55 (95% CI: 0.49-0.61), respectively. The median PFS varied from 1.5 to 6.1 months, and the median OS ranged from 5.9 to 28.9 months.
CONCLUSION
Atezolizumab has a considerable potential in treating cancers with an acceptable risk profile.

Meta-Analysis
BACKGROUND
There is evidence for the positive effects of neurodynamic techniques in some peripheral entrapment neuropathies, but the rationale for these effects has not been validated. We aimed to estimate the direct effect of neurodynamic techniques on the dispersion of artificially induced intraneural edema measured by dye spread in cadavers.
METHODS
We systematically searched the MEDLINE, WOS, Scopus, and the Cochrane databases from inception to February 2020 for experimental studies addressing the efficacy of neurodynamic techniques on the dispersion of artificially induced intraneural edema. The DerSimonian and Laird method was used to compute pooled estimates of the mean differences (MDs) and its respective 95% confidence intervals (CIs). Subgroup analyses were conducted according to the type of neurodynamic technique. In addition, a 95% prediction interval was calculated to reflect the variation in true treatment effects in different settings, including the effect to be expected in future patients.
RESULTS
Pooled results showed a significant increase in fluid dispersion (MD = 2.57 mm; 95%CI: 1.13 to 4.01). Subgroup analysis showed increased dye spread in the tensioning techniques group (MD = 2.22 mm; 95%CI: 0.86 to 3.57).
CONCLUSION
Neurodynamic techniques improved the intraneural edema dispersion and should be considered for the management of peripheral compression neuropathies. Furthermore, tensioning techniques appear to be effective in helping to disperse intraneural edema.

Review
BACKGROUND
At least 7000 major lower limb amputations (MLLAs) are performed in the UK each year, 80% of which are due to peripheral arterial disease (PAD). Intraoperative blood loss can have a deleterious effect on patient outcomes, and its replacement with transfused blood is not without risk. Tourniquets can be used in lower limb surgical procedures to provide a bloodless surgical field, minimise intraoperative blood loss, and reduce perioperative blood transfusion requirements. Although their safety has been demonstrated in certain orthopaedic operations, their use among people with PAD undergoing MLLA remains controversial. Many clinicians are concerned about tourniquets potentially compromising perfusion of the stump and thereby impacting wound healing through direct tissue injury, damage to the arterial supply of the wound, or both.
OBJECTIVES
To assess the safety and effectiveness of tourniquet use in people undergoing MLLA for complications of PAD, specifically with regard to intraoperative blood loss, change in haemoglobin levels, transfusion rates, wound healing, need for revision surgery, and postoperative complications including mortality.
SEARCH METHODS
We searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers from inception to 17 May 2022.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) comparing tourniquet use to no tourniquet use among people with PAD undergoing MLLA.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Primary outcomes were intraoperative blood loss, fall in haemoglobin levels, and perioperative blood transfusion requirement. Secondary outcomes were primary wound-healing rates, stump revision rates, other postoperative complications defined as per Clavien-Dindo classification, and postoperative mortality at 30 days and at maximal follow-up. We used GRADE to assess the certainty of evidence for each outcome.
MAIN RESULTS
One RCT met our inclusion criteria, which was a prospective randomised blinded controlled trial conducted in Sheffield, UK in 2006. In total 64 participants undergoing transtibial amputation for non-reconstructable PAD were randomised to either tourniquet or no tourniquet to assess for intraoperative blood loss, fall in haemoglobin, transfusion requirement, wound healing, stump breakdown and revision. Ten participants were excluded postrandomisation (five from the tourniquet group and five from the no tourniquet group). The reported median volume of intraoperative blood loss was significantly less in the tourniquet group (255 mL (interquartile range (IQR) 150 to 572.5 mL))) compared to the control group (550 mL (IQR 255 to 1050 mL)) (P = 0.014). There was a significantly lower median drop in haemoglobin concentration in the tourniquet group (1.0 g/dL (IQR 0.6 to 2.4 g/dL)) compared to the control group (1.8 g/dL (IRQ 0 to 1.2 g/dL)) (P = 0.035). There was a significantly lower perioperative blood transfusion requirement in the tourniquet group (8 participants, 32%) compared to the control group (14 participants, 48%) (P = 0.047). There were no clear differences in wound breakdown, stump revision, primary wound healing at six weeks, postoperative complications (myocardial infarction, cardiac arrhythmias, pulmonary oedema), and death between groups. We assessed the one included study as at low risk of bias for sequence generation and blinding of outcome assessors; high risk of bias for incomplete outcome data and selective outcome reporting; and unclear risk of bias for allocation concealment, blinding of participants and personnel, and other sources of bias. We assessed the certainty of the evidence as low or very low due to risk of bias, small sample size, and the study being insufficiently powered for most outcomes.
AUTHORS' CONCLUSIONS
This review identified only one small historical RCT evaluating tourniquet use in MLLA. Tourniquets appeared to reduce intraoperative blood loss, drop in haemoglobin, and blood transfusion requirements following transtibial amputations for people with PAD. However, it is unclear whether tourniquets affect wound healing, stump revision rates, postoperative complications, or mortality. High-certainty evidence is required to inform clinical decision-making for the use of tourniquets in these patients.

This systematic review investigates complications and recurrence of Dupuytren's contracture in metacarpophalangeal joints (MCPJs) and/or proximal interphalangeal joints (PIPJs) of fingers treated with collagenase clostridium histolyticum (CCH). A review of the literature on Dupuytren's disease was performed using PRISMA guidelines. Included publications described complications and/or recurrences for contractures ≥20° in MCPJs and/or PIPJs treated with CCH. Successful treatments reduced contractures to ≤5° immediately. Treatment-related adverse events (AEs) were classified as minor, major surgical, and major nonsurgical. Contracture recurrence involved return of fixed-flexion contracture ≥20° in a successfully treated finger in patients with ≥12 months of follow-up. Of 2675 patients (3753 joints), 94% experienced ≥1 treatment-related AE, most commonly peripheral edema (64%), pain in extremity (53%), and contusion (51%). Major surgical complications occurred in 9 patients (1.0%). Major nonsurgical complications occurred in 2 patients, specifically nonrupture tendon injury and anaphylaxis. Of 1488 patients (2069 joints), recurrences were reported in 23% of successfully treated joints (n = 466; 20% MCPJs, 28% PIPJs), on average 12 to 24 months after treatment. MCPJs achieved greater success than PIPJs in initial contracture reduction (77% versus 36%). CCH is a safe, effective treatment to improve hand function in Dupuytren's contracture. Most AEs are minor and self-resolving, although the risk of major AEs still exists. Following treatment, 23% of successfully treated joints experience recurrence, typically within 12 to 24 months but sometimes as early as 6 months. Surgeons are encouraged to discuss these risks with patients for shared decision-making regarding optimal treatment modalities.
