Meta-Analysis Review
Systematic review and meta-analysis of the effects of foot and ankle physical therapy, including mobilisations and exercises, in people with diabetic peripheral neuropathy on range of motion, peak plantar pressures and balance.
To evaluate the effects of foot and ankle physical therapy on ankle and first metatarsophalangeal joint range of motion (ROM), peak plantar pressures (PPPs) and balance in people with diabetes. MEDLINE, EBSCO, Cochrane Database of Systematic Reviews, Joanna Briggs Institute Database of Systematic Reviews, PROSPERO, EThOS, Web of Science and Google Scholar were searched in April 2022. Randomised Controlled Trials (RCT), quasi-experimental, pre-post experimental design and prospective cohort studies were included. Participants were people with diabetes, neuropathy and joint stiffness. Interventions included physical therapy such as mobilisations, ROM exercises and stretches. Outcome measures focused on ROM, PPPs and balance. Methodological quality was assessed with Critical Appraisal Skills Programme RCT and Risk-of-Bias 2 tool. Meta-analyses used random-effects models and data was analysed using the inverse variance method. In total, 9 studies were included. Across all studies, participant characteristics were similar; however, type and exercise dosage varied greatly. Meta-analysis was performed with four studies. Meta-analysis showed significant effects of combined exercise interventions in increasing total ankle ROM (3 studies: MD, 1.76; 95% CI, 0.78-2.74; p = 0; I = 0%); and reducing PPPs in the forefoot area (3 studies; MD, -23.34; 95% CI, -59.80 to 13.13; p = 0.21, I = 51%). Combined exercise interventions can increase ROM in the ankle and reduce PPPs in the forefoot. Standardisation of exercise programmes with or without the addition of mobilisations in the foot and ankle joints needs further research.

Meta-Analysis Review
BACKGROUND
Psychological interventions are effective at ameliorating the experience of pain in conditions such as rheumatoid arthritis and chronic back pain. However, their effect on diabetic peripheral neuropathy (DPN) pain has yet to be established AIM: To assess the effectiveness of psychological interventions on pain and related outcomes in adults with DPN.
DESIGN
Systematic review.
SETTINGS
Community, hospital in-patient and out-patient.
PARTICIPANTS/SUBJECTS
Adults with diabetic peripheral neuropathy.
METHODS
Medline, Embase, PsychInfo, and CINAHL databases together with grey literature and trial registers were searched. A meta-analysis and narrative synthesis of included studies were undertaken.
RESULTS
Nine studies were selected from 1610 citations. At short-term follow-up psychological therapies showed a large effect on pain severity (SMD = -0.94, 95%CI [-1.50, -0.37], p = .001), a small effect on pain interference (SMD = -0.39, 95%CI [-0.73, -0.05], p = .02), and a moderate effect on depressive symptoms (SMD = -0.58, 95%CI [-0.95, -0.21], p = .002). Quality of life significantly improved in experimental subjects, (MD = -2.35, 95%CI [-3.99, -0.71], p = .005). At medium-term follow-up there was a large effect on pain severity (SMD = -1.26, 95%CI [-1.76, -0.77], p < .00001) and on pain interference (SMD = -0.91, 95%CI [-1.61, -0.21], p = .01) and a moderate effect on depressive symptoms (SMD = -0.76, 95%CI [-1.48, -0.05], p = .04). At long-term follow-up, improvements in pain interference, mood, and self-care behaviors were reported.
CONCLUSIONS
These findings demonstrate that the relationship between pain and perceived control identified in other groups who experience chronic pain may also be replicated in the DPN population. This is an important outcome that can guide further research and associated service developments.

Meta-Analysis
BACKGROUND
Painful diabetic peripheral neuropathy (PDPN) is a key concern in clinical practice. In this systematic review and meta-analysis, we compared duloxetine and placebo treatments in terms of their efficacy and safety in patients with PDPN.
METHODS
Following the PRISMA guidelines, we searched the Cochrane Library, PubMed, and Embase databases for relevant English articles published before January 11, 2021. Treatment efficacy and safety were assessed in terms of pain improvement, patient-reported health-related performance, and patients' quality of life.
RESULTS
We reviewed a total of 7 randomized controlled trials. Regarding pain improvement, duloxetine was more efficacious than placebo (mean difference [MD] - 0.89; 95% confidence interval [CI] - 1.09 to - 0.69; P < .00001). Furthermore, duloxetine significantly improved the patients' quality of life, which was assessed using the Clinical Global Impression severity subscale (MD - 0.48; 95% CI - 0.61 to - 0.36; P < .00001), Patient Global Impression of Improvement scale (MD - 0.50; 95% CI - 0.64 to - 0.37; P < .00001), and European Quality of Life Instrument 5D version (MD 0.04; 95% CI 0.02 to 0.07; P = .0002). Severe adverse events were rare, whereas nausea, somnolence, dizziness, fatigue, constipation, and decreased appetite were common; approximately, 12.6% of all patients dropped out because of the common symptoms.
CONCLUSIONS
Duloxetine is more efficacious than placebo treatments in patients with PDPN. The rarity of severe adverse events indicates that duloxetine is safe. When a 60-mg dose is insufficient, 120 mg of duloxetine may improve PDPN symptoms. Our findings may help devise optimal treatment strategies for PDPN.

Review
BACKGROUND
A systematic review was conducted to investigate the prevalence of onychomycosis in patients with diabetes. The association of onychomycosis with risk factors in patients with diabetic foot syndrome was also examined.
METHODS
The recommendations in the preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist were applied, and the included studies were assessed using the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) method. Searches were conducted in October 2022 using PubMed (Medline) and Scopus for clinical studies, clinical trials, comparative studies, observational studies, and randomised clinical trials or controlled clinical trials addressing the prevalence and consequences of onychomycosis in patients with diabetes, diagnoses or treatments. Two authors performed the study selection and data extraction, and any discrepancies between the two reviewers were resolved through discussion with a third reviewer.
RESULTS
The systematic review included ten studies that met the inclusion criteria, and these studies enrolled 5664 patients with diabetes. Among these patients, 29.18% had onychomycosis that was mainly caused by Trichophyton rubrum. A significant association was found between the occurrence of onychomycosis and the presence of diabetic neuropathy (p = .012) and elevated glycosylated haemoglobin values (p = .039). There was no significant association between onychomycosis and ulceration (p = .185). Eight studies had a grade 4 level of evidence and a grade C recommendation, and one study had a grade 1b level of evidence and a grade A recommendation.
CONCLUSION
The information described in the literature is insufficient and heterogeneous regarding the association of risk factors and ulceration in patients with diabetic foot compared with developing onychomycosis. There is also a need to implement onychomycosis diagnostic testing instead of relying only on a clinical diagnosis. Additional prospective, randomised, comparative studies are needed to increase the quality of studies in the literature.

Review
Diabetes and hypertension stand as the major non-infectious diseases affecting 34.2 million and 1.28 billion people respectively. The literature on the impact of diabetes on hypertension and vice versa is evolving. The major objectives of this review were to compile the evolving literature establishing the role of hypertension in diabetic neuropathy, derive the exact mechanisms for its pathogenesis, and describe evidence-based precise individualized management of diabetic neuropathy in patients having diabetes complicated by hypertension. A systematic review was conducted by searching databases of PubMed, Embase, and Scopus covering the literature from inception to 2022. We included all observational and experimental studies, including both human and animal studies looking into the correlation between diabetic neuropathy and hypertension. Hypertension poses to be the leading modifiable risk factor for the development of diabetic neuropathy, especially distal symmetrical polyneuropathy, producing abnormal nerve conduction parameters and increased vibration perception threshold in patients with diabetes mellitus. Thus, we advocate that good glycemic control in patients with diabetes needs to be supported with strict blood pressure control for preventing and delaying the onset of diabetic neuropathy.

Meta-Analysis
BACKGROUND
Early identification and intervention of diabetic peripheral neuropathy is beneficial to improve clinical outcome.
OBJECTIVE
To establish a risk prediction model for diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM).
METHODS
The derivation cohort was from a meta-analysis. Risk factors and the corresponding risk ratio (RR) were extracted. Only risk factors with statistical significance were included in the model and were scored by their weightings. An external cohort were used to validate this model. The outcome was the occurrence of DPN.
RESULTS
A total of 95,604 patients with T2DM from 18 cohorts were included. Age, smoking, body mass index, duration of diabetes, hemoglobin A1c, low HDL-c, high triglyceride, hypertension, diabetic retinopathy, diabetic kidney disease, and cardiovascular disease were enrolled in the final model. The highest score was 52.0. The median follow-up of validation cohort was 4.29 years. The optimal cut-off point was 17.0, with a sensitivity of 0.846 and a specificity of 0.668, respectively. According to the total scores, patients from the validation cohort were divided into low-, moderate-, high- and very high-risk groups. The risk of developing DPN was significantly increased in moderate- (RR 3.3, 95% CI 1.5-7.2, = 0.020), high- (RR 15.5, 95% CI 7.6-31.6, < 0.001), and very high-risk groups (RR 45.0, 95% CI 20.5-98.8, < 0.001) compared with the low-risk group.
CONCLUSION
A risk prediction model for DPN including 11 common clinical indicators were established. It is a simple and reliable tool for early prevention and intervention of DPN in patients with T2DM.

Meta-Analysis Review
OBJECTIVE
Studies suggest that smoking may be a risk factor for the development of microvascular complications such as diabetic peripheral neuropathy (DPN). The objective of this study was to assess the relationship between smoking and DPN in persons with type 1 or type 2 diabetes.
RESEARCH DESIGN AND METHODS
A systematic review of the PubMed, Embase, and Cochrane clinical trials databases was conducted for the period from January 1966 to November 2014 for cohort, cross-sectional and case-control studies that assessed the relationship between smoking and DPN. Separate meta-analyses for prospective cohort studies and case-control or cross-sectional studies were performed using random effects models.
RESULTS
Thirty-eight studies (10 prospective cohort and 28 cross-sectional) were included. The prospective cohort studies included 5558 participants without DPN at baseline. During follow-up ranging from 2 to 10 years, 1550 cases of DPN occurred. The pooled unadjusted odds ratio (OR) of developing DPN associated with smoking was 1.26 (95% CI 0.86-1.85; I(2) = 74%; evidence grade: low strength). Stratified analyses of the prospective studies revealed that studies of higher quality and with better levels of adjustment and longer follow-up showed a significant positive association between smoking and DPN, with less heterogeneity. The cross-sectional studies included 27,594 participants. The pooled OR of DPN associated with smoking was 1.42 (95% CI 1.21-1.65; I(2) = 65%; evidence grade: low strength). There was no evidence of publication bias.
CONCLUSIONS
Smoking may be associated with an increased risk of DPN in persons with diabetes. Further studies are needed to test whether this association is causal and whether smoking cessation reduces the risk of DPN in adults with diabetes.

Meta-Analysis Review
OBJECTIVES
Neuromodulation is a treatment option for people suffering from painful diabetic neuropathy (PDN) unresponsive to conventional pharmacotherapy. We systematically examined the pain outcomes of patients with PDN receiving any type of invasive neuromodulation for treatment of neuropathic pain.
MATERIALS AND METHODS
MEDLINE and Embase were searched through 10 January 2020, without language restriction. All study types were included. Two reviewers independently screened publications and extracted data. Quantitative meta-analysis was performed with pain scores converted to a standard 100-point scale. Randomized controlled trial (RCT) scores were pooled using the inverse variance method and expressed as mean differences.
RESULTS
RCTs of tonic spinal cord stimulation (t-SCS) showed greater pain improvement than best medical therapy at six months (intention-to-treat: 38/100, 95% CI: 29-47). By per-protocol analysis, case series of t-SCS and dorsal root ganglion stimulation (DRGS) showed improvement by 56 (95% CI: 39-73) and 55 (22-87), respectively, at 12 months. For t-SCS, the rate of failing a therapeutic stimulation trial was 16%, the risk of infection was 4%, and the rate of lead problems requiring surgery to resolve was 4% per year of follow-up. High-frequency SCS and burst SCS both showed efficacy, with few patients studied.
CONCLUSION
Efficacious, lasting and safe surgical pain management options are available to diabetic patients suffering from PDN. Tonic-SCS is the established standard of treatment; however, other SCS paradigms and DRGS are emerging as promising treatments offering comparable pain benefits, but with few cases published to date. Randomized controlled trials are ongoing to assess their relative merits.

Review
PURPOSE
Diabetic foot disease is one of the most serious and expensive complications of diabetes. Patient-reported outcome measures (PROMs) analyse patients' perception of their disability, functionality and health. The goal of this work was to conduct a systematic review regarding the specific PROMs related to the evaluation of diabetic foot disease and to extract and analyse the values of their measurement properties.
METHODS
Electronic databases included were PubMed, CINAHL, Scopus, PEDro, Cochrane, SciELO and EMBASE. The search terms used were foot, diabet*, diabetic foot, questionnaire, patient-reported outcome, self-care, valid*, reliabil*. Studies whose did not satisfy the Critical Appraisals Skills Programme (CASP) Diagnostic Study Checklist were excluded. The measurement properties extracted were: Internal Consistency, Test-retest, Inter-rater and Intra-rater, Standard Error of Measurement, Minimum Detectable Measurement Difference, Content Validity, Construct Validity, Criterion Validity and Responsiveness.
RESULTS
The PROMs selected for this review were 12 questionnaires. The Diabetic foot self-care questionnaire (DFSQ-UMA) and the Questionnaire for Diabetes Related Foot Disease (Q-DFD) were the PROMs that showed the highest number of completed measurement properties.
CONCLUSION
According to the results, it is relevant to create specific questionnaires for the evaluation of diabetic foot disease. It seems appropriate to use both DFSQ-UMA and Q-DFD when assessing patients with diabetic foot disease.

Review
There is growing evidence of excess peripheral neuropathy in pre-diabetes. We aimed to determine its prevalence, including the impact of diagnostic methodology on prevalence rates, through a systematic review conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive electronic bibliographic search was performed in MEDLINE, EMBASE, PubMed, Web of Science and the Cochrane Central Register of Controlled Trials from inception to June 1, 2020. Two reviewers independently selected studies, extracted data and assessed risk of bias. An evaluation was undertaken by method of neuropathy assessment. After screening 1784 abstracts and reviewing 84 full-text records, 29 studies (9351 participants) were included. There was a wide range of prevalence estimates (2%-77%, IQR: 6%-34%), but the majority of studies (n=21, 72%) reported a prevalence ≥10%. The three highest prevalence estimates of 77% (95% CI: 54% to 100%), 71% (95% CI: 55% to 88%) and 66% (95% CI: 53% to 78%) were reported using plantar thermography, multimodal quantitative sensory testing and nerve conduction tests, respectively. In general, studies evaluating small nerve fiber parameters yielded a higher prevalence of peripheral neuropathy. Due to a variety of study populations and methods of assessing neuropathy, there was marked heterogeneity in the prevalence estimates. Most studies reported a higher prevalence of peripheral neuropathy in pre-diabetes, primarily of a small nerve fiber origin, than would be expected in the background population. Given the marked rise in pre-diabetes, further consideration of targeting screening in this population is required. Development of risk-stratification tools may facilitate earlier interventions.
