Analysis of Risk Factors for in-hospital Death in Elderly Patients with TEXAS Stage 3 and 4 Diabetic Foot Ulcers after Tibial Transverse Translation: A Case-Control Study. Orthop Surg 2023; 15:3272-3278. [PMID: 37814800 PMCID: PMC10694016 DOI: 10.1111/os.13908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/30/2023] [Accepted: 08/30/2023] [Indexed: 10/11/2023] Open
Abstract
OBJECTIVE Chinese physicians developed the Tibial Transverse Transport (TTT) technique to treat diabetic foot ulcers with more than 90% effective rate. But this method still could not avoid the in-hospital death of patients. This study adopted a case-control study to explore the risk factors of in-hospital death in elderly patients with chronic ischemic diabetic foot after receiving TTT treatment. METHODS A total of 54 patients were included in the study from January 1, 2017 to April 30, 2021, by being paired with the cases in case group with their demographic data and results of blood routine, liver and kidney function. There were nine patients in case group with six male and three male. Forty-five patients were selected in control group according to gender and diabetes type with 30 male and 15 female. Single factor logics regression analysis was used to explore the risk factors and odd ratios (OR) of in-hospital death in patients. The nomogram and decision curve analysis (DCA) had been done by R Studio software. RESULTS The study found that age, course of diabetic foot, small dense low-density Lipoprotein (smLDL), homocysteine (Hcy), superoxide dismutase (SOD), and prealbumin (PA) were risk factors for in-hospital death of patients. The smLDL had the highest risk. The nomogram showed that PA accounted for the largest proportion in the death risk factors. The results of DCA proved that above six risk factors were the risk factors for patients with TEXAS Stage 3 and 4 diabetic foot ulcers. CONCLUSION In the future diagnosis and TTT treatment for diabetic foot ulcers, doctors need to pay close attention to age, course of diabetic foot, smLDL, Hcy, SOD, and PA.

Abstract
Annually, 26 million people worldwide develop diabetic extremity wounds, adversely impacting the lives of patients and their family caregivers, who provide vital health assistance to these patients. This integrative review synthesized scientific literature of informal caregiving experiences for patients with diabetic extremity wounds. Five databases were searched for relevant English-language quantitative or qualitative research; ten studies were included in the final analysis. The caregiving experience included disrupted routines, frustration, guilt, poor health care communication, helplessness, and anxiety. Increased caregiver burden and decreased quality of life were associated with higher patient amputation level, worsening wound appearance and patient pain, poor health care communication, lack of social support and/or caregiving help, and lack of caregiver employment outside the home. Future research opportunities include further exploration of caregiver tasks and priorities, caregiving experiences in settings lacking family support structures and equitable health system access, and relationships between the caregiver experience and patient health system utilization.

Abstract
Chronic wound is a serious medical issue due to its high prevalence and complications; hyperbaric oxygen therapy (HBOT) is also considered in comprehensive treatment. Clinical trials, including large meta-analyses bring inconsistent results about HBOT efficacy. This review is summarizing the possible effect of HBOT on the healing of chronic wound models at the cellular level. HBOT undoubtedly escalates the production of reactive oxygen and nitrogen radicals (ROS and RNS), which underlie both the therapeutic and toxic effects of HBOT on certain tissues. HBOT paradoxically elevates the concentration of Hypoxia inducible factor (HIF) 1 by diverting the HIF-1 degradation to pathways that are independent of the oxygen concentration. Elevated HIF-1 stimulates the production of different growth factors, boosting the healing process. HBOT supports synthesis of Heat shock proteins (HSP), which are serving as chaperones of HIF-1. HBOT has antimicrobial effect, increases the effectiveness of some antibiotics, stimulates fibroblasts growth, collagen synthesis and suppresses the activity of proteolytic enzymes like matrix metalloproteinases. All effects of HBOT were investigated on cell cultures and animal models, the limitation of their translation is discussed at the end of this revie

Abstract
Diabetic foot ulcer (DFU) is a serious complication of diabetes and hyperbaric oxygen therapy (HBOT) is also considered in comprehensive treatment. The evidence supporting the use of HBOT in DFU treatment is controversial. The aim of this work was to introduce a DFU model in ZDF rat by creating a wound on the back of an animal and to investigate the effect of HBOT on the defect by macroscopic evaluation, quantitative histological evaluation of collagen (types I and III), evaluation of angiogenesis and determination of interleukin 6 (IL6) levels in the plasma. The study included 10 rats in the control group (CONT) and 10 in the HBOT group, who underwent HBOT in standard clinical regimen. Histological evaluation was performed on the 18th day after induction of defect. The results show that HBOT did not affect the macroscopic size of the defect nor IL6 plasma levels. A volume fraction of type I collagen was slightly increased by HBOT without reaching statistical significance (1.35+/-0.49 and 1.94+/-0.67 %, CONT and HBOT, respectively). In contrast, the collagen type III volume fraction was ~120 % higher in HBOT wounds (1.41+/-0.81 %) than in CONT ones (0.63+/-0.37 %; p=0.046). In addition, the ratio of the volume fraction of both collagens in the wound ((I+III)w) to the volume fraction of both collagens in the adjacent healthy skin ((I+III)h) was ~65 % higher in rats subjected to HBOT (8.9+/-3.07 vs. 5.38+/-1.86 %, HBOT and CONT, respectively; p=0.028). Vessels density (number per 1 mm2) was found to be higher in CONT vs. HBOT (206.5+/-41.8 and 124+/-28.2, respectively, p<0.001). Our study suggests that HBOT promotes collagen III formation and decreases the number of newly formed vessels at the early phases of healing.

Abstract
Diabetic foot (DF) is one of the most common complications of diabetes and is associated with high morbidity, disability, lethality and low cure-rate. The clinical diagnosis and treatment of DF need to be standardized. The Chinese Diabetic Foot Cell and Interventional Therapy Technology Alliance has released six editions of guidelines and standards for clinical diagnosis and interventional treatment of DF, which filled the gap in the domestic DF treatment standard and played an important role in improving the level of diagnosis and treatment in China. In line with the latest developments in diagnosis and treatment, the Alliance, along with other 89 institutions, developed and issued the new edition based on the sixth edition to help standardize the clinical diagnosis and treatment of DF in China.

Abstract
Objective To study the effectiveness of tibial transverse transport combined with the antibiotics embedded bone cement in the treatment of chronic infection of foot and ankle with lower extremity ischemic diseases. Methods A retrospective analysis was performed on 28 patients with ischemic diseases of lower extremities associated with chronic foot and ankle infection who were treated with tibial transverse transport combined with antibiotic bone cement between August 2015 and October 2019. There were 22 males and 6 females, with an average age of 65.6 years (range, 41-86 years). There were 25 cases of diabetic foot, 2 cases of arteriosclerosis obliterans, and 1 case of thromboangiitis obliterans. The course of infection ranged from 1 to 27 years, with an average of 14.9 years. The healing condition and time of foot and ankle in all patients were recorded and compared, and the Wagner grading and WIFi (W: lower extremity wound classification; I: ischemic classification; Fi: foot infection classification) grading were compared before and at last follow-up. Results The wound surface of 1 diabetic foot patient improved at 111 days after operation, without purulent secretion, and lost follow-up. The remaining 27 cases were followed up 5 to 21 months (mean, 8.4 months). There was no necrosis in the tibial osteotomy incision and the local flap. After operation, 21 cases showed needle reaction of external fixator, but the needle infection gradually improved after the corresponding treatment. Among the 24 patients with diabetic foot, 1 died of multiple organ failure due to pulmonary infection. Acute lower extremity vascular embolism occurred in 1 case, and the foot was amputated due to acute gangrene. In the remaining 22 cases, the wound healing time of foot and ankle was 2.5-11.0 months (mean, 4.6 months). At last follow-up, Wagner grading and WIFi grading of the patients were significantly improved when compared with those before operation ( P<0.05). One patient with thromboangiitis obliterans had foot and ankle healing at 6 months after operation. Two patients with lower extremity arteriosclerosis obliterans had foot and ankle healing at 16 and 18 months after operation, respectively. Conclusion Tibial transverse transport combined with the antibiotics embedded bone cement is effective in treating chronic infection of foot and ankle with lower extremity ischemic diseases.

Abstract
The diabetic foot is a complication of diabetes affecting 15% of diabetics in their lives. It is associated to diabetic neuropathy and peripheral vascular disease and its incidence has increased. The ulceration is the initial cause of a dramatic process leading, if not correctly treated, to amputations. Both neuropathy, neuro-ischemia and infections have a role in determining healing or worsening of the lesions and 85% of all amputations in diabetic patients are preceded by a foot ulceration deteriorating to a severe gangrene or infection. The different causative agents and the different clinical presentations of diabetic foot ask a multidisciplinary approach in order to address treatments to the final goals, the prevention of the amputations and the maintenance of a functional foot able with weight-bearing ability. Many professional figures, diabetologists, surgeons (both general and vascular and orthopedics), interventional radiologists, infectious diseases specialists, specialized nurses, podiatrists, orthotic technicians, are called to apply their knowledges to the diabetic patients affected by diabetic foot in a virtuous circle leading to reach the goals, with the imperative action of the multidisciplinary team. The so organized center will allow both a correct and rapid diagnosis, the use in ambulatorial environments of modern tools, or the hospitalization in multitasking wards, in which all the complications and the necessary treatments are possible, both in emergencies or in elective way, considering both revascularizations and surgery.

Abstract
Diabetic foot ulcer is a costly and serious complication of diabetes mellitus and is the major cause of non-traumatic limb amputations worldwide. Its development is primarily the result of diabetic neuropathy and/or peripheral arterial disease with accompanied bone abnormalities and is complicated by invasive infection. The management of this clinical condition focuses on identification of the "at-risk" foot, treatment of the ulcerated foot, and prevention of further complications. As diabetic foot ulcer represents the sum of multiple etiologies, its treatment requires a multidisciplinary team, which can result in a significant reduction in the incidence of ulcers, infections and amputations. The team should include a diabetologist, a podiatrist, an orthoptist, an educator and a plaster technician, in close collaboration with a vascular surgeon, an orthopedic/podiatric surgeon and a dermatologist. It is recommended that a diabetologist be the multidisciplinary team leader, as diabetic foot ulcer is a complication of diabetes and chronic hyperglycemia represents the main cause for its development. The appropriate composition of professionals involved in the team is institution-dependent and may vary worldwide, depending on the diabetic population. The concept of establishing a diabetic foot care team is recommended by all National and International Diabetes Scientific Societies and Associations.

Abstract
Abstract Introduction: Diabetes Mellitus is a chronic disease with high prevalence in the population in particular among the elderly. The longer time of diabetes, increased the chances of developing complications such as peripheral neuropathy, which is an important factor in the genesis of plantar lesions by changing the distribution and formation of plantar pressure peaks. Objective: Evaluate the influence of an Assistive Technology, therapeutic footwear for diabetics, in the peaks of plantar pressure of elderly. Methods: This was an experimental study of transversal type, composed by 10 elderly, diabetic, with peripheral neuropathy, using as an instrument to measure a baropodometry platform. Were measured peaks of plantar pressure, static and dynamic in three situations: barefoot, the participants' own standard footwear and with therapeutic footwear for diabetics. Data analysis by normal distribution as a single paired sample, applying the ANOVA test. Results: The use of therapeutic footwear for diabetics promoted a reduction in media of peak plantar pressure in the order of 22% in static analysis, and 31% in dynamic analysis. Conclusion: The therapeutic footwear for diabetics was able to produce significant reductions in peak plantar pressure, being more efficient than a common footwear. This effect may contribute to the prevention of injuries associated with the diabetic foot.

Abstract
BACKGROUND Foot ulceration is the main precursor to lower limb amputation in patients with type 2 diabetes worldwide. Biomechanical factors have been implicated in the development of foot ulceration; however the association of these factors to ulcer healing remains less clear. It may be hypothesised that abnormalities in temporal spatial parameters (stride to stride measurements), kinematics (joint movements), kinetics (forces on the lower limb) and plantar pressures (pressure placed on the foot during walking) contribute to foot ulcer healing. The primary aim of this study is to establish the biomechanical characteristics (temporal spatial parameters, kinematics, kinetics and plantar pressures) of patients with plantar neuropathic foot ulcers compared to controls without a history of foot ulcers. The secondary aim is to assess the same biomechanical characteristics in patients with foot ulcers and controls over-time to assess whether these characteristics remain the same or change throughout ulcer healing. METHODS/DESIGN The design is a case-control study nested in a six-month longitudinal study. Cases will be participants with active plantar neuropathic foot ulcers (DFU group). Controls will consist of patients with type 2 diabetes (DMC group) and healthy participants (HC group) with no history of foot ulceration. Standardised gait and plantar pressure protocols will be used to collect biomechanical data at baseline, three and six months. Descriptive variables and primary and secondary outcome variables will be compared between the three groups at baseline and follow-up. DISCUSSION It is anticipated that the findings from this longitudinal study will provide important information regarding the biomechanical characteristic of type 2 diabetes patients with neuropathic foot ulcers. We hypothesise that people with foot ulcers will demonstrate a significantly compromised gait pattern (reduced temporal spatial parameters, kinematics and kinetics) at base line and then throughout the follow-up period compared to controls. The study may provide evidence for the design of gait-retraining, neuro-muscular conditioning and other approaches to off-load the limbs of those with foot ulcers in order to reduce the mechanical loading on the foot during gait and promote ulcer healing.

Abstract
PURPOSE Peripheral neuropathy (PN) is known as a major contributor of the worsening of ischemic symptoms and the foot ulceration in patients with peripheral arterial occlusive disease (PAOD). However, there are few studies reporting the prevalence and risk factors for PN in PAOD. This study aimed to evaluate these issues for PN and to establish the importance of screening as additional treatment target for PN in PAOD. MATERIALS AND METHODS A total of 52 limbs with PAOD were enrolled from January 2011 to December 2012. PN was divided into radiculopathy, ischemic PN (IPN), and diabetic PN (DPN), based on electromyographic findings. We investigated the prevalence of overall PN and subtypes of PN and then analyzed the risk factors. RESULTS The prevalence of overall PN in PAOD was 43 of 52 limbs (82.7%). In terms of subtypes of PN, the prevalence rate of radiculopathy and IPN was 30.8% and 23.1%, respectively. DPN showed in 22 limbs (73.3%) among 30 diabetic limbs. There was no significant correlation between each type of PN and ischemic symptoms. Our analysis showed that coronary artery disease (CAD) was a significant risk factor (P=0.01) for IPN, however, did not identify any significant risk factors for DPN. CONCLUSION This present study indicated that most patients with PAOD had PN and CAD was a risk factor for IPN. In particular, PAOD with diabetes represented a higher prevalence for DPN. Our study suggests that PN should be evaluated and considered as another treatment target in patients with PAOD.

Early revascularization after admittance to a diabetic foot center affects the healing probability of ischemic foot ulcer in patients with diabetes. Eur J Vasc Endovasc Surg 2014; 48:440-6.

Abstract
OBJECTIVES There is limited information about whether time from recognition of decreased perfusion to revascularization affects the probability of healing in a patient with a diabetic foot ulcer. The aim of the present study was to examine whether time to revascularization after referral to a multidisciplinary foot center was related to the outcome of foot ulcers in patients with diabetes and severe peripheral arterial disease (PAD). METHODS Patients with diabetes, a foot ulcer, and a systolic toe pressure <45 mmHg or an ankle pressure <80 mmHg were prospectively included at the foot center, and considered for revascularization according to a preset protocol. All patients underwent invasive revascularization, either percutaneous transluminal angioplasty (PTA) or reconstructive vascular surgery. All patients had continuous follow-up until healing or death irrespective of the type of revascularization. RESULTS A total of 478 patients were included (age 74 [range 66-80] years, 60% males), of whom 315 patients (66%) had PTA, and 163 (34%) had reconstructive surgery. Of the 478 patients, 217 (45%) healed primarily, 88 (19%) healed after a minor amputation, 76 (16%) healed after a major amputation and 92 patients (19%) died unhealed. The median time from inclusion in the study to revascularization was 8 weeks (3-18 weeks). Time to vascular intervention within 8 weeks (p < .001), maximum Wagner grade reached <3 (p < .001), absence of peripheral edema (p = .033), and presence of intermittent claudication (p = .001) were related to a higher probability of healing. CONCLUSIONS Time to revascularization and extent of tissue damage were related to the probability of healing of ischemic foot ulcer in patients with diabetes over time. In the presence of a decreased perfusion in a patient with diabetes and a foot ulcer not only revascularization per se but also timing of revascularization is important for the possibility of healing without a major amputation.

Abstract
AIMS To determine the prevalence of foot ulcers and the incidence of amputations in patients with Type 2 diabetes observed for 19 years after diagnosis. We investigated the role of gender, age and co-morbidities. METHODS From the Diabetes Care in General Practice study, 1381 patients were included and examined at diabetes diagnosis, at 6 years and at 14 years after diagnosis. Register-based follow-up was for 19 years. Foot ulcers and amputations were related to gender, age and co-morbidities by odds and hazard ratios from logistic and Cox regression models, respectively. RESULTS The incidence of any amputation and major amputation was 400 (95% CI 307-512) and 279 (95% CI 203-375) per 100,000 patient-years, respectively. At the three observation points, the foot ulcer prevalences were 2.76% (95% CI 1.89-3.63), 2.93% (95% CI 1.86-4.00) and 4.96% (95% CI 3.10-6.82). Multivariate analyses showed associations between foot ulcers and peripheral neuropathy, peripheral arterial disease, male gender, retinopathy and myocardial infarction. After multivariate adjustment, significant predictors (hazard ratio; 95% CI) of any amputation were peripheral neuropathy (hazard ratio 2.09; 95% CI 1.19-3.69), peripheral arterial disease (hazard ratio 3.43; 95% CI 1.65-7.12), microalbuminuria (hazard ratio 2.11; 95% CI 1.21-3.67), retinopathy (hazard ratio 6.42; 95% CI 2.59-15.90), impaired vision (hazard ratio 6.92; 95% CI 2.35-20.38) and male gender (hazard ratio 2.40; 95% CI 1.31-4.41). For women, the risk of amputation increased with age, but for men the risk was higher when diagnosed with diabetes at a younger age. CONCLUSIONS Despite improved treatment regimens, the incidence of amputations is still high in this population-based patient sample. Men diagnosed with diabetes before age 65 years and patients with diabetes-related co-morbidities are at particularly high risk of foot ulcers and amputations.

Abstract
AIMS To evaluate multi-frequency tactilometry as a method to measure vibrotactile sense in the sole of the foot in subjects with diabetes. METHODS Vibration thresholds were investigated at five frequencies (8, 16, 32, 64 and 125 Hz) at three sites (first and fifth metatarsal heads and heel) in the sole of the foot in subjects with Type 1 and Type 2 diabetes (n = 37). Thresholds were compared with healthy, age- and gender-matched subjects (n = 37) and related to glycaemic levels, subjective estimation of sensation in the feet and to perception of touch. RESULTS Vibration thresholds were significantly higher in subjects with diabetes compared with healthy subjects at low frequencies (8, 16 and 32 Hz) at all measured sites, and also at 64 Hz for the metatarsal heads. Perception of touch and subjective estimation of sensation were significantly impaired in subjects with diabetes. Glycaemic levels, which were higher in subjects with diabetes, did not correlate with vibration thresholds at 32 Hz (most sensitive to Meissner's corpuscles) or with touch thresholds in subjects with diabetes. Vibration thresholds at 32 Hz correlated significantly with perception of touch (rho = 0.45-0.65; P < 0.01) and with subjective sensation (rho = -0.38 to -0.52; P < 0.001) in subjects with diabetes. Perception of touch and subjective estimation of sensation did also correlate (rho = -0.51 to -0.80; P < 0.002). CONCLUSIONS Tactilometry is effective in detecting neuropathy in the sole of the foot at low frequencies of mainly 8-32 Hz, indicating that at least Meissner's corpuscles, or their related large nerve fibres, are affected by diabetes.

Abstract
Every 30 s, a lower limb is amputated due to diabetes. Of all amputations in diabetic patients 85% are preceded by a foot ulcer which subsequently deteriorates to a severe infection or gangrene. There is a complexity of factors related to healing of foot ulcers including strategies for treatment of decreased perfusion, oedema, pain, infection, metabolic disturbances, malnutrition, non-weight bearing, wound treatment, foot surgery, and management of intercurrent disease. Patients with diabetic foot ulcer and decreased perfusion do often not have rest pain or claudication and as a consequence non-invasive vascular testing is recommended for early recognition of ulcers in need of revascularisation to achieve healing. A diabetic foot infection is a potentially limb-threatening condition. Infection is diagnosed by the presence or increased rate of signs inflammation. Often these signs are less marked than expected. Imaging studies can diagnose or better define deep, soft tissue purulent collections and are frequently needed to detect pathological findings in bone. The initial antimicrobial treatment as well as duration of treatment is empiric. There is a substantial delay in wound healing in diabetic foot ulcer which has been related to various abnormalities. Several new treatments related to these abnormalities have been explored in wound healing with various successes. An essential part of the strategy to achieve healing is an effective offloading. Many interventions with advanced wound management have failed due to not recognizing the need for effective offloading. A multidisciplinary approach to wounds and foot ulcer has been successfully implemented in different centres with a substantial decrease in amputation rate.

Abstract
Ulcerated diabetic foot is a complex problem. Ischaemia, neuropathy and infection are the three pathological components that lead to diabetic foot complications, and they frequently occur together as an aetiologic triad. Neuropathy and ischaemia are the initiating factors, most often together as neuroischaemia, whereas infection is mostly a consequence. The role of peripheral arterial disease in diabetic foot has long been underestimated as typical ischaemic symptoms are less frequent in diabetics with ischaemia than in non-diabetics. Furthermore, the healing of a neuroischaemic ulcer is hampered by microvascular dysfunction. Therefore, the threshold for revascularising neuroischaemic ulcers should be lower than that for purely ischaemic ulcers. Previous guidelines have largely ignored these specific demands related to ulcerated neuroischaemic diabetic feet. Any diabetic foot ulcer should always be considered to have vascular impairment unless otherwise proven. Early referral, non-invasive vascular testing, imaging and intervention are crucial to improve diabetic foot ulcer healing and to prevent amputation. Timing is essential, as the window of opportunity to heal the ulcer and save the leg is easily missed. This chapter underlines the paucity of data on the best way to diagnose and treat these diabetic patients. Most of the studies dealing with neuroischaemic diabetic feet are not comparable in terms of patient populations, interventions or outcome. Therefore, there is an urgent need for a paradigm shift in diabetic foot care; that is, a new approach and classification of diabetics with vascular impairment in regard to clinical practice and research. A multidisciplinary approach needs to implemented systematically with a vascular surgeon as an integrated member. New strategies must be developed and implemented for diabetic foot patients with vascular impairment, to improve healing, to speed up healing rate and to avoid amputation, irrespective of the intervention technology chosen. Focused studies on the value of predictive tests, new treatment modalities as well as selective and targeted strategies are needed. As specific data on ulcerated neuroischaemic diabetic feet are scarce, recommendations are often of low grade.

Lipoprotein(a) and homocysteine as genetic risk factors for vascular and neuropathic diabetic foot in type 2 diabetes mellitus. Endocrine 2012; 41:89-95.

Abstract
Neuropathy and peripheral artery disease represent the main pathophysiological conditions underlying diabetic foot. Several studies showed that Lipoprotein(a)-Lp(a)-and homocysteine (Hcy) can be associated with diabetic complications, but their relationship with diabetic foot is unclear. Aim of this study was to investigate whether Lp(a) and Hcy were associated with diabetic foot ulcerations, classified according to the presence of peripheral artery disease (PAD) or neuropathy. From among consecutive type 2 diabetic attending at the Diabetic Foot Clinic 27 subjects with vascular diabetic foot (VDF), 43 with neuropathic diabetic foot (NDF) and 52 controls without foot ulceration, neuropathy, and PAD were enrolled. Both Lp(a) (26.1 ± 22.7 vs. 14.9 ± 19.5 mg/dl; P = 0.003) and Hcy levels (15.4 ± 5.7 vs. 12.2 ± 5.1 μmol/l; P = 0.022) were significantly greater in the VDF group than in controls. Lp(a) levels were significantly lower in the NDF group than in controls (6.9 ± 8.1 versus 14.9 ± 19.5 mg/dl; P = 0.009), while no difference in Hcy levels was found. Multiple logistic regression analysis showed that Hcy was associated with VDF (OR: 1.11; 95% CI: 1.07-14.1; P = 0.048). Lp(a) did not enter the model, but its P-value was very near to the significant level (OR: 1.09; 95% CI: 0.99-12.05; P = 0.059). Moreover, low Lp(a) levels were associated with NDF (OR: 0.84; 95% CI: 0.21-0.96; P = 0.039). Our study has shown for the first time that high Lp(a) and Hcy levels are associated with the development of VDF, while low Lp(a) levels appear to be associated with delayed wound healing in patients with neuropathic foot ulcerations.

Abstract
OBJECTIVES To identify areas of improvement in diabetic foot care as regards the availability of materials and specialties in primary and secondary care. To determine the model of care for surgical centres and hospitals caring for diabetic foot problems and their relation to amputations. DESIGN Cross-sectional study SETTING AND PARTICIPANTS Random sample of 36 basic health areas (BHA) and all hospital surgery centres in Catalonia (Spain). MEASUREMENTS Information was collected by structured interview of managers of each centre on: availability of specialists, material off-loading and examination. The models were established according to the classification of Van Acker, and amputations from hospital discharge records. RESULTS An endocrinologist was available in 36.1% [confidence interval (CI) 95%:19.0-53.2] of the BHA and 11.1% [95% CI: 3.1-26.1] had a podiatrist,100% [95% CI: 90.3-100.0] had Doppler, 91.7% [95% CI:77.5-98.2] a monofilament, 5.6% [95% CI: 0.7-18.7] a quantitative tuning fork, 11.1% [95% CI:3,1-26, 1] material off-loading, and 8.3% [95% CI: 1.8 - 22.5] a specialist reference centre. A total of 85 surgical centres and hospitals dealt with these problems: 11(13.0%) excellent model, 29 (34.1%) intermediate and 45 (52.9%) basic/insufficient. Centres with a basic model/insufficient performed 12.5% of the amputation, intermediate models, 56.4%, and 31.1% in excellent models. CONCLUSIONS The proportion of ABS with materials, specialists and/or specialist reference centres was low. The basic/insufficient model was the most common among surgical/hospital centres. Most amputations were performed in centres with excellent and intermediate model; nevertheless, a considerable percentage was performed in centres with basic/insufficient models.

Abstract
The polymicrobial nature of diabetic foot infection is a reflection of the immune compromised state of the host.The methods of microbial identification based on colony morphology and biochemical characteristics have limitations as they may not differentiate the diverse microorganisms that infect foot wounds. The aim of the present study was to find out the bacterial diversity in diabetic foot infections at genetic level by finger printing, that is, ERIC-PCR (enterobacterial repetitive intergenic consensus -polymerase chain reaction). Nine patients with infected diabetic foot ulcers were recruited to the study. Pus and tissue samples were collected from the wound site. Aerobic bacteria were isolated employing standard microbiological culture methods and their genetic variability was analyzed using the ERIC-PCR. Sensitivity test for these isolates against commonly used antibiotics were performed using disc diffusion method. The standard microbiological culture technique yielded 38 morphotypes of bacteria and their genetic diversity was confirmed by ERIC-PCR assay. Analysis of the similarity index using NTSYSpc 2.1 software revealed 34 types of banding pattern among these isolates. Based on the similarity index these isolates were divided into 7 groups. As many as 8 types of aerobic bacterial isolates were detected from a single patient using the above technique compared with 2 on routine culture analysis. Genetically diverse isolates showed differential sensitivity pattern against commonly used antibiotics in the assay. The observed diversity at genetic level is attributed to variable sensitivity pattern of these isolates against the class of antibiotics. A molecular technique such as ERIC-PCR is a more sensitive detection method than conventional techniques, the potential of which needs to be fully understood.

Abstract
AIMS/HYPOTHESIS We sought to identify factors related to short-term outcome of foot ulcers in patients with diabetes treated in a multidisciplinary system until healing was achieved. METHODS Consecutively presenting patients with diabetes and worst foot ulcer (Wagner grade 1-5, below ankle) (n = 2,511) were prospectively followed and treated according to a standardised protocol until healing was achieved or until death. The number of patients lost to dropout was 31. The characteristics of the remaining 2,480 patients were: 1,465 men, age 68 +/- 15 years (range 18-96), type 1 diabetes 18%, type 2 diabetes 82% and insulin-treated 62%. RESULTS The healing rate without major amputation in surviving patients was 90.6% (n = 1,867). Sixty-five per cent (n = 1,617) were healed primarily, 9% (n = 250) after minor amputation and 8% after major amputation; 17% (n = 420) died unhealed. Out of 2,060 surviving patients, 1,007 were neuroischaemic (48.8%). In a multiple regression analysis, primary healing was related to co-morbidity, duration of diabetes, extent of peripheral vascular disease and type of ulcer. In neuropathic ulcers, deep foot infection, site of ulcer and co-morbidity were related to amputation. Amputation in neuroischaemic ulcers was related to co-morbidity, peripheral vascular disease and type of ulcer. Age, sex, duration of diabetes, neuropathy, deformity and duration of ulcer or site of ulcer did not have an evident influence on probability of amputation. CONCLUSIONS/INTERPRETATION Patients with diabetic foot ulcer suffer from multi-organ disease. Factors related to outcome are correspondingly complex.
