Exploring the influence of dietary habits on foot risk in type 2 diabetes patients: An observational study

Background & AimTo date, there are no studies demonstrating the impact of the Mediterranean diet on the risk of diabetic foot ulcer. The aim of this research was to examine the connection between adherence to the Mediterranean diet and the level of risk of diabetic foot ulcers in individuals with type 2 diabetes. MethodsObservational pilot study collecting sociodemographic, anthropometric, lifestyle, and type 2 diabetes-related data. Loss of protective sensation was assessed using the Semmes Weinstein 5.07-10g monofilament, considered altered when not perceived in four points. Vascular status was assessed by palpating pulses and ankle-brachial index, indicating peripheral arterial disease if ankle-brachial index was less than 0.9 or if both pulses were absent. Foot deformities were recorded. The risk of diabetic foot ulcers was stratified into two categories: no risk and risk of diabetic foot ulcers. Adherence to the Mediterranean diet was evaluated using the Mediterranean Diet Adherence Screener-14 questionnaire (good adherence with score > 7). ResultsOf the 174 patients with type 2 diabetes mellitus who participated (61.5% men and 38.5% women) with a mean age of 69.56 ± 8.86 years and a mean duration of type 2 diabetes of 15.34 ± 9.83 years. Non-adherent patients to the Mediterranean diet exhibited a higher association of diabetic foot ulcers (p=0.030) and a lower average score on the Mediterranean Diet Adherence Screener-14 (p=0.011). Additionally, a lower incidence of diabetic foot ulcers was observed in those who consumed nuts three or more times a week (p=0.003) and sautéed foods two or more times a week (p=0.003). Multivariate analysis highlighted the importance of physical activity (OR=0.25, 95% CI 0.11-0.54; p<0.001), podiatric treatment (OR=2.59, 95% CI 1.21-5.56; p=0.014), and duration of type 2 diabetes (OR=3.25, 95% CI 1.76-5.99; p<0.001) as significantly associated factors related to the risk of diabetic foot ulcers. ConclusionsAdhering to the Mediterranean diet correlates with a lower incidence of diabetic foot ulcers in individuals diagnosed with type 2 diabetes mellitus. Furthermore, factors such as regular physical activity, podiatric treatment, and the duration of type 2 diabetes mellitus emerge as pivotal in preventing diabetic foot ulcers.

Improving foot ulcer risk assessment and identifying associated factors: Results of an initiative enhancing diabetes care in primary settings

BackgroundDiabetes-related lower extremity complications contribute significantly to the overall disability burden of type 2 diabetes (T2D). The screening of Diabetic Foot Ulcer (DFU) risk is essential for the early identification of its components, thereby preventing the progression to advanced complications. Unfortunately, identifying elements associated with foot ulcer development is often poorly executed, especially in primary care settings, particularly in low-middle-income countries. We assess the prevalence of DFU risk and its components while exploring sociodemographic, clinical, and behavioral characteristics linked to DFU risk in patients with T2D. MethodsThis cross-sectional study examined the characteristics of the feet of subjects involved in an initiative to enhance the quality of diabetes care in primary healthcare settings. The assessment included the presence of foot deformities, peripheral neuropathy through Loss of Protective Sensation (LOPS) evaluation, peripheral arterial disease (PAD), and a history of foot ulcer or lower extremity amputations. Participants were classified according to the IWGDF Risk Classification and subsequently divided into two groups for analysis: those at high risk for DFU (Groups 1, 2, or 3) and those at low risk for DFU (Group 0). Logistic regression was employed to identify the factors associated with DFU risk and its components. ResultsAmong the 1361 patients evaluated, 63.8 % were found to be at an increased risk for DFU. The reported prevalence of foot deformities, LOPS, PAD, and a history of foot ulcer was 91.9 %, 44.3 %, 36.5 %, and 4.5 %, respectively. In the adjusted analysis, factors significantly associated with DFU risk included male gender (OR =2.01; 95 % IC 1.54–2.61), secondary education or less (OR =1.65, 95 % IC 1.27–2.14), diabetes duration exceeding 10 years (OR = 1.75, 95 % IC 1.34–2.30), chronic kidney disease (OR =1.44, 95 % IC 1.11 – 1.88), diabetic retinopathy (OR =1.93, 95 % IC 1.42–2.62), onychomycosis (OR =1.46, 95 % IC 1.14–1.88) properly cut toenails (OR =0.60, 95 % IC 0.45–0.79), and sedentary behavior (OR =1.56, 95 % IC 1.14–2.14). ConclusionsRisk assessment of DFU within a comprehensive care program for adults with T2D receiving conventional primary care showed that a substantial proportion of these patients are at an increased risk and, thus, qualify as candidates for interventions aimed at mitigating foot-related risks. We recommend that diabetes healthcare schemes incorporate preventive organizational interventions to facilitate the timely identification of DFU risk, particularly in primary care scenarios, thereby alleviating the burden of diabetes-related lower limb complications.

Effects of individually optimized rocker midsoles and self-adjusting insoles on plantar pressure in persons with diabetes mellitus and loss of protective sensation

IntroductionRocker shoes and insoles reduce peak pressure (PP) in persons with diabetes (DM) and loss of protective sensation (LOPS). However, they are handmade, leading to inconsistent effectiveness. If foot structure changes over time, high PP-locations also change. To address this, individualized algorithm based 3D-printed rockers and self-adjusting pressure-reducing insoles are applied. MethodsPP across seven foot regions was analyzed in 21 persons with DM and LOPS. Regions with PP < 200 kPa were considered not at risk (RnoR); regions with PP ≥ 200 kPa at risk (RaR). The aim was to offload RaR, while remaining PP < 200 kPa in RnoR. ResultsIndividualized rockers and self-adjusting insoles combined successfully reduce PP < 200 kPa (on average 24 % - 48 %) in all feet with toes, central and lateral forefoot identified as RaR. Same intervention reduces PP in 68 % of the feet with medial forefoot identified as RaR. With the heel as RaR, no intervention reduces PP successfully in all feet. ConclusionsIndividualized 3D-printed rockers combined with self-adjusting insoles reduce PP (< 200 kPa) in toes, central and lateral forefoot, but not in heels. Alternative insoles with medial arch support, heel cup and compliant midsole materials might enhance success rate across entire foot.

Behavior of neuropathy symptom score and neuropathy disability score in patients with and without peripheral diabetic neuropathy: A retrospective cohort study

BackgroundThis study aimed to stablish cut-off of early diagnosis of diabetic polyneuropathy (PDN) based on neuropathy symptom score (NSS) and neuropathy disability score (NDS); to determine the behavior of NDD and NDS in patients with and without PDN; and to verify the association between clinical and demographic variables with both tests. MethodsThis retrospective cohort included 86 patients with diabetes. The NSS and NDS evaluations were collected in medical records in two moments: initial (entry into service) and final (after three years). Individuals were categorized in three groups: G1- PDN in both evaluations (N = 27); G2- PDN only in the final evaluation (N = 16); G3-individuals without PDN (N = 43). A ROC curve was performed to evaluate the sensitivity and specificity of NSS and NDS for PDN diagnosis. ANOVA was used to compare NSS and NDS between groups and evaluations, and multiple regression was performed to find predictors of PDN. ResultsThe NSS and NDS showed excellent sensitivity and specificity (NDS ≥1.5 and NSS ≥6.5) for PDN diagnosis. There was a significant difference between groups in initial (p = 0.000) and final (p = 0.000) NDS and NSS evaluations. There was an association between peripheral arterial disease (PAD) and increase in NSS (p = 0.024) in G2; and association between loss of protective sensation (LOPS) and increase in NSS in G3 (p < 0.001). ConclusionNSS and NDS tests showed excellent sensitivity and specificity for early PDN diagnosis. Behavior of both tests can differ patients with and without PDN. Furthermore, PAD and LOPS can be a predictor of PDN evolution.

The value of loss of protective pain sensation in predicting afirst ulceration of the foot in people with diabetes.

To determine both the risk of first ever ulcer (FEU) and its time to onset in a population which had loss of protective sensation (LOPS) in the foot either with or without loss of protective pain (LOPP). People with diabetes and LOPS without history of FEU presenting in a specialist clinic were included. LOPP was diagnosed by reduced vibration perception and pain perception by using a pinprick simulator. Participants were followed by routine foot checks, phone interview or by letter until the occurrence of a FEU, death or the end of observation period. Survival functions in LOPP strata were compared by log rank test. The hazard ratio (HR) of an FEU in people with compared to people without LOPP was estimated using Cox regression. Time to first ulcer was estimated using the framework of an accelerated failure time (AFT) model. One hundred and thirty participants were followed up for a median of 48.3 months. Pain perception was lost in 55.4%. Eighteen people with LOPP developed a FEU (25.0%) as opposed to six (10.3%) of those with no LOPP (p = 0.02). Age-sex-adjusted HR for FEU was 3.0 (p = 0.02) for people with compared to people without LOPP. Age-sex-adjusted time to FEU for people with LOPP was approximately half (p = 0.03) than people without LOPP. It is suggested that estimation of LOPP is included in routine practice because of its high predictive value for a FEU.

Charcot arthropathy outcomes after early referral to a regional tertiary care foot clinic.

Community physicians may not encounter Charcot arthropathy frequently, and its symptoms and signs may be nonspecific. Patients often have a delay of several months before receiving a formal diagnosis and referral for specialty care. However, limited Canadian data are available. We evaluated the clinical history, treatment and outcomes of patients treated for Charcot arthropathy after prompt referral and diagnosis. We performed a retrospective chart review of 76 patients with diabetes (78 feet) who received nonoperative treatment for Charcot arthropathy in a specialty foot clinic between Jan. 20, 2009, and Mar. 26, 2018. Patients were referred to the foot clinic by community physicians for evaluation or were pre-existing patients at the foot clinic with new-onset Charcot arthropathy. Of the 78 feet included in our analyses, 52 feet (67%) were evaluated initially by a community physician and referred to the foot clinic, where they were seen within 3 ± 5 weeks. The remaining 26 feet (33%) were already being treated at the foot clinic. Most feet had swelling, erythema, warmth, a palpable pulse and loss of protective sensation. Ulcers were present initially in 23 feet (29%). Sixty-four feet (82%) with Charcot arthropathy were in Eichenholtz classification stage 1 and most had midfoot involvement. Nonoperative treatment included total contact casting (60 feet, 77%). Mean duration of nonoperative treatment until resolution for 55 feet (71%) was 6 ± 5 months. Surgery was performed on 20 feet (26%) for the treatment of infection and recurrent ulcer associated with deformity, including 6 (8%) lower limb amputations. Charcot arthropathy may resolve in most feet with early referral and nonoperative treatment, but remains a limb-threatening condition.

Effects of heel apex position, apex angle and rocker radius on plantar pressure in the heel region

IntroductionRocker shoes and insoles are used to prevent diabetic foot ulcers in persons with diabetes mellitus and loss of protective sensation, by reducing the plantar pressure in regions with high pressure values (>200 kPa) (e.g., hallux, metatarsal heads and heel). However, forefoot rocker shoes that reduce pressure in the forefoot inadvertently increase pressure in the heel. No studies focused on mitigating the negative effects on heel pressure by optimizing the heel rocker midsole, yet. Therefore, we analyze the effect of different heel rocker parameters on the heel plantar pressure. MethodsIn-shoe pressure was measured, while 10 healthy participants walked with control shoe and 10 different heel rocker settings. Peak pressure was determined in 7 heel masks, for all shoes. Generalized estimating equations was performed to test the effect of the different shoes on the peak pressure in the different heel masks. ResultsIn the proximal heel, a rocker shoe with distal apex position, small rocker radius and large apex angle (100°), shows the largest significant decrease in peak pressure compared to rocker shoes with more proximally located apex positions. In the midheel and distal heel, the same rocker shoes or any other rocker shoes, analyzed in this study, do not reduce the PP more than 2 % compared to the control shoe. For the midheel and distal heel region with high pressure values (>200 kPa), rocker shoes alone are not the correct option to reduce the pressure to below 200 kPa. ConclusionWhen using rocker shoes to reduce the pressure in the forefoot, a heel rocker midsole with a distal apex position, small rocker radius and apex angle of 100°, mitigates the negative effects on proximal heel pressure. For the midheel and distal heel, other footwear options as an addition or instead of rocker shoes are needed to reduce the pressure.

Effective and clinically relevant optimisation of cushioning stiffness to maximise the offloading capacity of diabetic footwear

IntroductionOptimising the cushioning stiffness of diabetic footwear/orthoses can significantly enhance their offloading capacity. This study explores whether optimum cushioning stiffness can be predicted using simple demographic and anthropometric parameters. MethodsSixty-nine adults with diabetes and loss of protective sensation in their feet were recruited for this cross-sectional observational study. In-shoe plantar pressure was measured using Pedar® for a neutral diabetic shoe (baseline) and after adding cushioning footbeds of varying stiffness. The cushioning stiffness that achieved maximum offloading was identified for each participant. The link between optimum cushioning stiffness and plantar loading or demographic/anthropometric parameters was assessed using multinomial regression. ResultsPeople with higher baseline plantar loading required stiffer cushioning materials for maximum offloading. Using sex, age, weight, height, and shoe-size as covariates correctly predicted the cushioning stiffness that minimised peak pressure across the entire foot, or specifically in the metatarsal heads, midfoot and heel regions in 70%, 72%, 83% and 66% of participants respectively. ConclusionsIncreased plantar loading is associated with the need for stiffer cushioning materials for maximum offloading. Patient-specific optimum cushioning stiffness can be predicted using five simple demographic/anthropometric parameters. These results open the way for methods to optimise cushioning stiffness as part of clinical practice.

The effectiveness of motivational interviewing on adherence to wearing orthopedic shoes in people with diabetes at low-to-high risk of foot ulceration: A multicenter cluster-randomized controlled trial

AimTo evaluate the effectiveness of motivational interviewing (MI) performed by MI-trained podiatrists in improving adherence to wearing orthopedic shoes in comparison to usual care in people with diabetes at low-to-high risk of ulceration. MethodsPeople with diabetes with loss of protective sensation and/or peripheral artery disease, and with orthopedic shoes prescription were allocated to receive one MI-consultation by a podiatrist randomized to MI training (n = 53) or usual care only (n = 68). Adherence was measured as the percentage of steps taken while wearing orthopedic shoes, determined using an insole temperature microsensor and wrist-worn activity tracker during one week at 3 and 6 months. ResultsThe proportion of participants ≥80 % adherent to wearing their orthopedic shoes was higher in the control group than in the MI-intervention group at 3 months (30.9 % versus 15.1 %; p = 0.044), and not significantly different at 6 months (22.1 % versus 13.2 %; p = 0.210). Average adherence was also higher in the control group than the intervention group at both 3 months (60.9 % versus 50.9 %; p = 0.029) and 6 months (59.9 % versus 49.5 %; p = 0.025). ConclusionsOne podiatrist-led MI-consultation in its current form did not result in higher adherence to wearing orthopedic shoes in people with diabetes 3 and 6 months after inclusion.Trial registration: Netherlands Trial Register NL7710 (available on the International Clinical Trials Registry Platform).

Screening for the loss of protective sensation in people without a history of diabetic foot ulceration: Validation of two simple tests in India

The ability of the Ipswich touch test (IpTT) and VibratipTM to detect loss of protective sensation (LOPS) was tested against a neurothesiometer in an outpatient diabetic population without a history for ulceration. Our results support the use of the IpTT as a screening tool for LOPS, but not of VibratipTM.

Multifactorial causes of chronic itch in diabetes: More than just neuropathy.

Chronic pruritus is common in patients with diabetes though its pathophysiology is unknown and difficult to pinpoint given the multi-system manifestations of diabetes. Herein, we aim to evaluate the severity of chronic itch in patients with diabetes and its association with glycaemic control, microvascular complications and quality of life. We conducted a retrospective study of 105 adults with diabetes evaluated by a dermatologist at a tertiary care centre in Mexico City. Degree of chronic pruritus and its impact on quality of life as well as laboratory, clinical and demographic data were collected. Patients without chronic pruritus (n = 62) were compared to those with chronic pruritus (n = 43). The latter cohort was further stratified by itch severity, and characteristics of their itch were quantified. Neuropathy and loss of protective sensation were more common in patients with chronic pruritus, compared to those without chronic pruritus (p = 0.007 and p = 0.001, respectively). Anxiety and depression were more common in individuals with chronic pruritus (p = 0.009), and these group reported higher effect of pruritus on their quality of life (p < 0.0001). The most common sites of itch were the head, back and arms. Among patients with chronic itch, increasing itch severity was associated with decreasing eGFR (p = 0.080). The underlying cause of chronic itch in patients with diabetes is likely multifactorial and owing to microvascular complications such as neuropathy and nephropathy. Better understanding of the causes of itch in these patients can allow for more targeted treatment, leading to improved quality of life.

ID: 211765 Multiple RCTs of SCS Show Consistent Outcomes in the Treatment of Painful Diabetic Peripheral Neuropathy

Diabetic peripheral neuropathy (DPN) is the most common neuropathic syndrome seen in patients with diabetes. DPN symptoms include stabbing or burning pain eventually progressing to numbness in the lower extremities resulting in loss of protective sensation. Traditionally, pain associated with DPN has been treated with gabapentin/pregabalin, tri-cycling antidepressants, and serotonin-norepinephrine reuptake inhibitors1. These treatment approaches are often unsuccessful in the long-term, with many DPN patients abandoning initial prescription analgesics within months1. Spinal Cord Stimulation (SCS) has been examined in 3 randomized controlled trials (RCTs)2,3,4 comparing SCS to conventional treatments.

Risk Factors for Hospital Re-admission for Diabetes Related Foot Disease: A Prospective Cohort Study

Diabetes related foot disease (DFD) is a common reason for admission to hospital, but the predictive factors for repeat admission are poorly defined. The primary aim of this study was to identify rates and predictive factors for DFD related hospital re-admission. Patients admitted to hospital for treatment of DFD at a single regional centre were recruited prospectively between January 2020 and December 2020. Participants were followed for 12 months to evaluate the primary outcome of hospital re-admission. The relationship between predictive factors and re-admission were examined using non-parametric statistical tests and Cox proportional hazard analyses. The median age of the 190 participants was 64.9 (standard deviation 13.3) years and 68.4% were male. Forty-one participants (21.6%) identified themselves as Aboriginal or Torres Strait Islander people. One hundred participants (52.6%) were re-admitted to hospital at least once over 12 months. The commonest reason for re-admission was for treatment of foot infection (84.0% of first re-admission). Absent pedal pulses (unadjusted hazard ratio [HR] 1.90; 95% confidence interval [CI] 1.26 - 2.85), loss of protective sensation (LOPS) (unadjusted HR 1.98; 95% CI 1.08 - 3.62), and male sex (unadjusted HR 1.62; 95% CI 1.03 - 2.54) increased the risk of re-admission. After risk adjustment, only absence of pedal pulses (HR 1.92, 95% CI 1.27 - 2.91) and LOPS (HR 2.02, 95% CI 1.09 - 3.74) significantly increased the risk of re-admission. Over 50% of patients admitted to hospital for treatment of DFD are re-admitted within one year. Patients with absent pedal pulses and those with LOPS are twice as likely to be re-admitted.

OUTPATIENT PERCUTANEOUS ULTRASOUND-GUIDED FLEXOR TENOTOMY FOR NEUROPATHIC APICAL TOE ULCERS

Percutaneous flexor tenotomy involves cutting the flexor digitorum tendons to correct claw toe deformity to treat apical pressure areas and prevent subsequent infection in patients with peripheral neuropathy. Performing this under ultrasound guidance provides reassurance of complete release of the tendon and increases procedural safety.This study is a retrospective case series evaluating the effectiveness, safety, and patient satisfaction of performing percutaneous ultrasound-guided flexor tenotomy in an outpatient setting. People with loss of protective sensation, a digital flexion deformity, and an apical toe ulcer or pre-ulcerative lesion who presented to our institution between December 2019 and June 2022 were included in this study. Participants were followed-up at a minimum of 3 months. Time to ulcer healing, re-ulceration rate, patient satisfaction, and complications were recorded. An Australian cost analysis was performed comparing this procedure performed in rooms versus theatres.There were 28 ulcers and 41 pre-ulcerative lesions. A total of 69 tenotomy procedures were performed on 38 patients across 52 episodes of care. The mean time to ulcer healing was 22.5 +/- 6.4 days. There were 2 cases of re-ulceration. 1 patient sustained a transfer lesion. There were four toes that went onto require amputation, all in the setting of pre-existing osteomyelitis. 94% of patients strongly agreed that they were satisfied with the outcome of the procedure. Costs saved were estimated to be $1426.Flexor tenotomy is a minimally invasive procedure that can be performed in the outpatient setting, and therefore without delay to treatment, reducing risk of ulcer progression and need for subsequent amputation. This is the first study to report on flexor tenotomy under ultrasound-guidance.Ultrasound-guided percutaneous flexor tenotomy is safe and effective, with high patient satisfaction and low recurrence rates. This performance in the outpatient setting ensures significant time and cost savings for both the practitioner and patient.

Factors influencing the use of therapeutic footwear in persons with diabetes mellitus and loss of protective sensation: A focus group study.

Persons with diabetes mellitus (DM) and loss of protective sensation (LOPS) due to peripheral neuropathy do not use their therapeutic footwear (TF) consistently. TF is essential to prevent foot ulceration. In order to improve compliance in using TF, influencing factors need to be identified and analyzed. Persons with a history of foot ulceration may find different factors important compared with persons without ulceration or persons who have never used TF. Therefore, the objective of this study was to determine factors perceived as important for the use of TF by different groups of persons with DM and LOPS. A qualitative study was performed using focus group discussions. Subjects (n = 24) were divided into 3 focus groups based on disease severity: ulcer history (HoU) versus no ulcer history (no-HoU) and experience with TF (TF) versus no experience (no-TF). For each group of 8 subjects (TF&HoU; TF&no-HoU; no-TF&no-HoU), an online focus group discussion was organized to identify the most important influencing factors. Transcribed data were coded with Atlas.ti. The analysis was performed following the framework approach. The factors comfort and fit and stability/balance were ranked in the top 3 of all groups. Usability was ranked in the top 3 of group-TF&noHoU and group-noTF&noHoU. Two other factors, reducing pain and preventing ulceration were ranked in the top 3 of group-TF&noHoU and group-TF&HoU, respectively. Experience with TF and a HoU influence which factors are perceived as important for TF use. Knowledge of these factors during the development and prescription process of TF may lead to increased compliance. Although the main medical reason for TF prescription is ulcer prevention, only 1 group gave this factor a high ranking. Therefore, next to focusing on influencing factors, person-centered education on the importance of using TF to prevent ulcers is also required.

Objectively assessed long-term wearing patterns and predictors of wearing orthopaedic footwear in people with diabetes at moderate-to-high risk of foot ulceration: a 12 months observational study

BackgroundOrthopaedic footwear can only be effective in preventing diabetic foot ulcers if worn by the patient. Robust data on long-term wearing time of orthopaedic footwear are not available, and needed to gain more insights into wearing patterns and associated factors (i.e. participants’ demographic, disease-related characteristics, and footwear usability). We aimed to objectively assess long-term wearing patterns and identify factors associated with wearing orthopaedic footwear in people with diabetes at moderate-to-high risk of ulceration.MethodsPeople diagnosed with diabetes mellitus type 1 and 2 with loss of protective sensation and/or peripheral artery disease and prescribed with orthopaedic footwear were included and followed for 12 months. The primary outcome was mean daily wearing time, continuously measured using a temperature sensor inside the footwear (Orthotimer®). Adherence to wearing orthopaedic footwear was calculated as percentage of wearing time of a total assumed 16 h out-of-bed daytime, where adherence < 60% was a pre-determined non-adherent threshold. Wearing time patterns were assessed by calculating participants’ wearing (in)consistency. One-way analyses of variance tested for wearing time differences between subgroups, weekdays, and weekend days. Factors potentially associated with wearing time were collected by questionnaires and medical files. Univariately associated factors were included in multivariate linear regression analysis.ResultsSixty one participants were included (mean (SD) age: 68.0 (7.4) years; females: n = 17; type 2 diabetes mellitus: n = 54). Mean (SD) overall daily wearing time was 8.3 (6.1) hours/day. A total of 40 (66%) participants were non-adherent. Participants with a consistent wearing pattern showed higher daily wearing times than participants with an inconsistent pattern. Mean (SD) wearing times were 12.7 (4.3) vs 3.6 (4.8) hours/day, respectively (P < 0.001). Mean (SD) wearing time was significantly higher (P < 0.010) during weekdays (8.7 (6.0) hours/day) compared to Saturday (8.0 (6.1) hours/day) and Sunday (6.9 (6.2) hours/day). In the multivariate model (R2 = 0.28), “satisfaction with my wear of orthopaedic footwear” was positively associated (P < 0.001) with wearing time. The other seven multivariate model factors (four demographic variables and three footwear usability variables) were not associated with wearing time.ConclusionsOnly one out of three people at moderate to high risk of foot ulceration were sufficiently adherent to wearing their orthopaedic footwear. Changing people’s wearing behaviour to a more stable pattern seems a potential avenue to improve long-term adherence to wearing orthopaedic footwear. Investigated factors are not associated with daily wearing time. Based on these factors the daily wearing time cannot be estimated in daily practice.Trial registrationNetherlands Trial Register NL7710. Registered: 6 May 2019.

Preventing diabetes-related foot ulcers through early detection of peripheral neuropathy.

Peripheral neuropathy, peripheral arterial disease and diabetes-related foot ulcers are the most important risk factors for future amputation. Up to 50% of people with diabetes have distal symmetrical polyneuropathy as a complication of diabetes. Distal symmetrical polyneuropathy results in loss of protective sensation in the feet, increasing the risk of diabetes-related foot ulceration. The aim of this article is to provide structured guidance for detecting diabetes-related peripheral neuropathy, appropriate referral based on risk assessment and prevention of diabetes‑related foot ulceration. As a result of the often-asymptomatic nature of diabetes-related peripheral neuropathy, general practice is an ideal location for screening all adults with diabetes for loss of protective sensation. Loss of protective sensation in a person with diabetes indicates an at-risk foot. Increased frequency of foot examination, education in self-care, appropriate footwear and referral to podiatry for non‑ulcerative foot problems can reduce the development of diabetes-related footulcers.

Knowledge and Practice of Physicians About Vitamin B12 deficiency among Type 2 Diabetes Mellitus patients in Buraidah, Saudi Arabia

Objectives:&#x0D; To assess knowledge and practice of physicians regarding Vitamin B12 Screening among Type 2 diabetes mellitus (T2DM) and assess knowledge of physicians about recent American diabetic association (ADA) guidelines updates.&#x0D; Methods:&#x0D; A cross sectional study was conducted at Primary Health Care (PHC) centers in Buraidah, Qassim from January to April 2022. Data was collected using a structured questionnaire which was based on ADA guidelines among all physicians of PHCs. Statistical package for social sciences (SPSS) version 23.0 was used for analysis. Frequencies and percentages were calculated for categorical variables and means with standard deviations were calculated for continuous variables.&#x0D; Results:&#x0D; About 135 (72.2%) physicians would test T2DM patients who are on metformin for Vitamin B12, and only 65 (34.8) would test them annually. Early signs of Diabetic peripheral neuropathy (DPN) are pain, burning sensation, tangling sensation, numbness and loss of protective sensation (LOPS). Only 23 (12.3%) of them knew the all five symptoms. Forty-five (45.5%) of participants would not treat DPN with B12 supplementation. Only (57.2%) order Vit B12 testing for DM2 who are on metformin, and (49.2%), (29.4%) would order them if the patient has neuropathy and on annual basis respectively. Majority of physicians (70.6%) give Vit B12 supplements as treatment of DPN.&#x0D; Conclusions:&#x0D; There is poor knowledge and practices related to B12 deficiency among primary care physicians. This calls for training and educating primary care physicians regarding B12 deficiency screening, neuropathy and their management. There is also need for providing sufficient resources in order to ensure B12 screening in high risk diabetic patients.
