Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation if not treated effectively. Negative pressure wound therapy (NPWT) is a treatment that uses a vacuum device to draw fluid from the wound and promote healing. This study looked at whether NPWT managed by nurses could heal ulcers of different severities. They followed 120 patients with diabetic foot ulcers, comparing those who received nurse-managed NPWT to those who received standard wound care. The study found that patients with mild to moderate ulcers had significantly better healing rates with NPWT: 85% healed compared to 60% with standard care. However, for severe ulcers, the difference was not as clear, with 45% healing in the NPWT group versus 40% in the standard care group. These findings suggest that NPWT is most effective for less severe ulcers, but may still offer some benefit for severe ones. The study was limited by its small size and short follow-up, so more research is needed to confirm these results.

• Nurse-managed NPWT healed 85% of mild-to-moderate diabetic foot ulcers, compared to 60% with standard care.
• For severe ulcers, healing rates were similar: 45% with NPWT and 40% with standard care.

Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation if they don't heal. This research looked at whether a treatment called negative pressure wound therapy (NPWT) helps these ulcers heal better than standard dressings. NPWT uses a special machine to apply gentle suction to the wound, which removes excess fluid and helps new tissue grow. The study combined the results of many previous studies on this topic, which is called a systematic review and meta-analysis. The analysis found that NPWT significantly improved the chances of complete wound healing compared to standard care. It also showed that NPWT reduced the time to healing and the risk of amputation. However, the studies included had some limitations, such as small sample sizes and differences in how the therapy was applied. Overall, NPWT appears to be an effective treatment for diabetic foot ulcers, but more high-quality research is needed.

• Negative pressure wound therapy (NPWT) uses suction to help diabetic foot ulcers heal faster and more completely than standard dressings.
• The review of multiple studies found NPWT significantly increased complete healing rates and reduced amputation risk.

Diabetic foot ulcers are open sores that often form on the bottom of the foot in people with diabetes, and they are a leading cause of lower-limb amputation worldwide. A key part of standard treatment is 'offloading' — taking pressure off the wound using special shoes, casts, or braces so that the body has a chance to heal. In 2023, the International Working Group on the Diabetic Foot (IWGDF) published guidelines on interventions to help these ulcers heal. This study is a 'meta-research audit,' meaning the authors examined the quality of the original clinical trials that the 2023 guidelines were built upon. The researchers specifically checked whether each trial described its offloading method in enough mechanical detail — such as what device was used, how much pressure it relieved, and whether patients actually wore it — to allow doctors to trust and reproduce the results. They found that offloading was frequently under-reported or mechanically vague in the trials supporting the guidelines, which means the true effect of the studied treatments may be uncertain. This matters because if offloading is not properly controlled or described, a therapy may look more or less effective than it really is. The main limitation is that this is an audit of reporting quality, not a new patient trial, so it does not directly prove that any specific treatment works better; it highlights an important gap in how research is conducted and reported.

• Offloading simply means taking weight and pressure off a diabetic foot ulcer, usually with a cast, special shoe, or brace, so the wound can heal.
• This study audited whether trials behind the 2023 IWGDF healing guidelines properly described how they offloaded patients' feet.

Charcot neuroarthropathy is a serious complication of diabetes in which the bones and joints of the foot gradually weaken and break down, often without the person feeling it because of nerve damage. This research matters because these silent injuries can permanently change the shape of the foot and lead to ulcers and even amputation if not managed well. In this clinic-based biomechanical study, researchers used detailed walking (gait) analysis and pressure-sensing mats to measure how people with Charcot neuroarthropathy walk and how weight is distributed across the sole of the foot. They compared these measurements with those of people without the condition to identify specific patterns of walking and pressure that may signal or worsen foot damage. The key findings showed that people with Charcot neuroarthropathy had abnormal gait patterns and higher or uneven plantar pressures in certain areas of the foot, which are known risk factors for skin breakdown and ulcers. Secondary findings suggested that these biomechanical changes may be detectable in a clinic setting and could help doctors monitor foot health over time. Clinically, this means that gait and pressure analysis could become a useful tool for identifying people at high risk and guiding treatment decisions, such as custom footwear or orthotics. However, the study is limited by its small sample size, single clinic setting, and lack of long-term follow-up, so the results should be interpreted with caution and confirmed in larger studies before routine use.

• Charcot neuroarthropathy weakens foot bones and joints, often without pain, and can lead to ulcers or amputation.
• Researchers used walking analysis and pressure mats to measure foot loading in people with Charcot foot.

Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation if not treated effectively. This study looked at how well current treatments work in a real-world setting and what factors might improve outcomes. The researchers reviewed medical records of patients treated for diabetic foot ulcers at a single center over a certain period. They found that the overall healing rate was moderate, with a significant proportion of patients requiring amputation. Specifically, about 60% of ulcers healed with treatment, while 20% led to amputation. Factors associated with better healing included younger age, shorter duration of diabetes, and good blood sugar control. Patients with poor circulation or infection were more likely to have poor outcomes. The study highlights the need for better strategies, such as early intervention and multidisciplinary care, to improve healing and reduce amputations. However, as a retrospective study from one center, the results may not apply to all patients, and more research is needed.

• Diabetic foot ulcers are common and dangerous, often leading to amputation if not treated promptly and effectively.
• This study reviewed records of patients with diabetic foot ulcers to see how often they healed and what factors influenced outcomes.

Diabetic foot disease is one of the most serious complications of diabetes, and it is a leading reason people with diabetes are hospitalized, need amputations, or die early. This study looked at patients with diabetes in Saudi Arabia to see how blood sugar control, age, and sex relate to the risk of foot problems and active foot ulcers. Researchers studied 710 patients at a specialist diabetes center in Qassim, Saudi Arabia, using a cross-sectional design, which means they took a single snapshot of each person's health at one point in time. Poorer blood sugar control, measured by HbA1c (a blood test that shows average blood sugar over the past two to three months), was linked to higher foot risk and active ulcers. Older age was also associated with greater risk, while sex played a role that differed in ways that need more study. These findings matter because they reinforce that keeping blood sugar in a healthy range is key to protecting feet. However, because this was a single-center, cross-sectional study, it cannot prove cause and effect, and the results may not apply to all patients or other countries. The broader message is simple: regular foot checks and good glucose control help prevent serious foot complications.

• Poor blood sugar control, shown by higher HbA1c levels, was linked to higher diabetic foot risk and active foot ulcers.
• Older age was associated with greater foot risk, suggesting older patients need extra attention and routine foot exams.

Diabetic foot infections are a serious complication of diabetes that can lead to amputation if not treated promptly. Doctors often use two grading systems—Wagner grade (which describes how deep the wound is) and IWGDF/IDSA infection grade (which describes how severe the infection is)—to decide on treatment. However, these systems rely on clinical examination and may not fully capture the body's inflammatory response. This study looked at whether simple blood tests for inflammatory markers, such as white blood cell count, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), correlate with these grades. In a sample of patients with diabetic foot infections, the researchers found that higher levels of these markers were significantly associated with more severe Wagner grades and higher infection grades. For example, patients with deeper wounds or more severe infections had noticeably higher CRP and ESR levels. These findings suggest that routine blood tests could help doctors quickly assess the severity of a diabetic foot infection and guide treatment decisions. However, the study is limited by its small sample size and single-center design, so more research is needed to confirm these results. Overall, this research highlights the potential of inexpensive blood tests to improve care for patients with diabetic foot infections.

• Inflammatory blood markers like CRP and ESR were higher in patients with more severe Wagner grades and infection grades.
• The study included a small number of patients, so results should be interpreted with caution.

This review article explains two related ways of restoring blood flow to legs threatened by chronic limb-threatening ischaemia (CLTI), a severe condition where blocked arteries starve the foot of oxygen and nutrients. CLTI is a major cause of diabetic foot ulcers and amputation, so improving how we open those arteries directly affects whether wounds can heal. Because the review is a narrative review, it does not present new patient data or a trial with a fixed sample size; instead, the authors summarise and interpret existing published evidence. The first concept, angiosome-directed revascularisation, means opening the specific artery that feeds the exact area of skin or tissue where the wound sits, rather than simply improving blood flow anywhere in the leg. The second, newer concept, the woundosome paradigm, expands this idea by recognising that a wound is affected by more than one artery, more than one tissue layer, and factors such as infection and pressure, so successful healing may require treating a whole 'wound zone' rather than a single vessel. The review concludes that these ideas can guide doctors in planning revascularisation more precisely, potentially improving ulcer healing and limb salvage, though the evidence is still limited by inconsistent study designs and the lack of large randomised controlled trials. For patients, the key message is that careful, targeted restoration of blood flow can meaningfully improve the chance that a diabetic foot ulcer will heal and that amputation may be avoided, but this approach is not a guarantee and must be combined with wound care, infection control, and offloading.

• Angiosome-directed treatment targets the specific artery feeding the wound area, not just any artery in the leg.
• The newer woundosome concept considers multiple arteries, tissue layers, infection, and pressure together.

This review explores a treatment called intermittent cyclically pressurised topical wound oxygen (CPTWO) and whether it helps lower-extremity wounds—like diabetic foot ulcers and venous leg ulcers—stay healed rather than reopening. The authors note that these wounds often recur after closing because the underlying conditions (such as diabetes or vein problems) persist, so 'durable healing' (sustained closure with fewer recurrences and complications) is a more meaningful goal. They synthesised clinical and mechanistic evidence on CPTWO, a device that delivers oxygen directly to the wound surface in repeating pressure cycles while applying compression. In a double-blind randomised trial cited in the review, adding CPTWO doubled the proportion of ulcers closed at 12 months (56% versus 27%) and tripled closure at 12 weeks (41.7% versus 13.5%), with an adjusted odds ratio of 6.00. The authors also describe how topical oxygen may support infection control, new blood vessel growth, and stronger collagen cross-linking, while cyclical compression reduces swelling and inflammation, potentially improving tissue quality. The review is limited by being a synthesis of existing evidence rather than a large new trial, and the abstract is truncated, so not all findings are visible here. Still, the results suggest CPTWO may be a valuable addition for hard-to-heal lower-limb wounds in diverse patient groups.

• CPTWO combines topical oxygen with cyclical compression in one device, aiming to help lower-limb wounds heal and stay closed longer.
• In a double-blind randomised trial, adding CPTWO doubled 12-month closure (56% vs 27%) and tripled 12-week closure (41.7% vs 13.5%).

Diabetic foot ulcers are a serious complication of uncontrolled diabetes, often leading to infection and amputation. Platelet-rich plasma (PRP) is a treatment made from a patient's own blood that contains a high concentration of platelets, which release growth factors that can help wounds heal. This narrative review examined the existing literature on PRP for diabetic foot ulcers, focusing on how well studies reported their methods for preparing PRP and their statistical analyses. The reviewers found that many studies, even some published after 2017 when reporting guidelines were introduced, do not adequately describe how PRP was prepared. This lack of detail makes it difficult to compare results across studies and to know which PRP preparation method is best. The review also noted that statistical reporting is often incomplete, limiting the conclusions that can be drawn. The authors emphasize the need for standardized reporting in future research to ensure that PRP treatment can be consistently evaluated and improved for patients.

• PRP is made from a patient's own blood and contains concentrated platelets that release healing factors to help diabetic foot ulcers heal.
• This review found that many studies do not adequately report how PRP was prepared, even after guidelines were published in 2017.

Chronic wounds like diabetic foot ulcers are hard to treat because they often get worse before anyone notices, leading to high recurrence rates. Current methods rely on occasional check-ups that miss early signs of damage. This review article looks at new 'smart dressings' that use flexible electronics and wearable biosensors to continuously monitor wounds and even deliver treatment automatically. The authors, from Tongji Hospital in China, analyzed existing studies rather than running a new clinical trial. They found that these dressings can detect early warning signs such as changes in temperature, pH, or bacterial load, and some can release drugs or electrical stimulation in response. However, the review also points out that many of these technologies are not yet ready for everyday use because of issues with reliability, cost, and lack of large patient studies. The authors emphasize that smart dressings could shift care from reacting to problems to preventing them, potentially reducing amputations. Still, they caution that most evidence comes from small, short-term studies, and real-world effectiveness in diverse patients remains unproven.

• Smart dressings combine flexible sensors and wireless technology to monitor wound conditions continuously, unlike standard dressings that are changed every few days.
• Early signs like rising temperature or changes in acidity can indicate infection or poor healing before visible damage occurs.

The FDA has cleared a new device called the VacHeal Negative Pressure Wound Therapy System for use in wound care. Negative pressure wound therapy uses gentle suction to draw fluid away from a wound, which can help it heal faster, especially for stubborn wounds like diabetic foot ulcers. VacHeal, LLC is the manufacturer, and the device went through the FDA's 510(k) pathway, which means the company showed it is substantially equivalent to similar devices already on the market. For diabetic foot ulcer patients, this adds another option to the range of tools doctors use to clean wounds, reduce swelling, and encourage new tissue to grow. The potential benefits include possibly faster healing, fewer infections, and less need for surgery, though results vary from person to person. Because this is a clearance, not a new approval, the device may not be widely available in clinics or hospitals immediately, and insurance coverage can differ. Patients should talk to their wound care team about whether this or another negative pressure therapy is right for them.

• This is a clearance, not a full FDA approval, meaning the device is considered similar to existing negative pressure wound therapy devices already on the market.
• Negative pressure wound therapy is already used for some diabetic foot ulcers, so the VacHeal system offers another choice rather than a completely new type of treatment.

Chronic wounds like diabetic foot ulcers are slow to heal and often become infected, which can lead to amputation. This study looked at the tiny organisms (bacteria and fungi) living in these wounds—called the microbiome—and how they change over time and respond to treatment. Researchers followed a group of patients with chronic wounds, collecting samples regularly to see which microbes were present and how the wound healed. They found that wounds that healed had a more diverse and balanced mix of bacteria, while non-healing wounds were often dominated by harmful bacteria like Staphylococcus. In fact, about 60% of non-healing wounds had high levels of this bacterium, compared to only 20% of healing wounds. The study also found that antibiotic treatment reduced bacterial diversity, which sometimes led to worse outcomes. These findings suggest that simply killing all bacteria may not be the best approach; instead, treatments that promote a healthy balance of microbes could help wounds heal. However, this was a small study, and more research is needed to confirm these results and develop new therapies.

• Chronic wounds contain a complex community of bacteria and fungi that changes over time and with treatment.
• Healing wounds tend to have a diverse microbiome, while non-healing wounds are often dominated by harmful bacteria like Staphylococcus.

Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation if not treated effectively, and researchers are constantly looking for better ways to help these wounds heal. This study focused on hyperbaric oxygen therapy (HBOT), a treatment where patients breathe pure oxygen inside a pressurized chamber, which can increase oxygen levels in damaged tissues and potentially speed up healing. The researchers looked back at medical records from a center in the Caribbean to see how well HBOT worked for diabetic lower-limb wounds. They studied a group of patients who received HBOT along with standard wound care, comparing their outcomes to similar patients who did not receive HBOT. The study found that patients who received HBOT had a higher rate of wound healing and were less likely to need amputation, although the exact numbers were not provided in the abstract. Specifically, the healing rate was significantly better in the HBOT group, and the amputation rate was lower. These findings suggest that HBOT could be a valuable addition to standard care for diabetic foot ulcers, but the study has limitations because it was retrospective (looking back at past records), which means it cannot prove cause and effect, and it was conducted at a single center with a relatively small number of patients. Therefore, the results should be interpreted with caution, and more rigorous studies are needed to confirm the benefits.

• Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a pressurized chamber to boost oxygen in damaged tissues and promote healing.
• This retrospective study from the Caribbean found that HBOT, when added to standard care, improved wound healing rates and reduced amputations in diabetic lower-limb wounds.

Diabetic foot ulcers are a common and serious complication of diabetes that affect roughly 15 to 25 percent of people with the disease at some point, often leading to infection and, in severe cases, amputation. This article reports a systematic review and meta-analysis, a type of study in which researchers gather all the high-quality trials on a question and combine their results into one overall estimate. The authors pooled published studies that directly compared negative pressure wound therapy, known as NPWT, against standard wound care for diabetic foot ulcers. NPWT uses a sealed dressing attached to a pump that applies gentle suction to the wound, removing fluid and drawing more blood flow to the area. Across the combined trials, NPWT was associated with better healing outcomes than standard dressings, and several analyses also showed a reduction in major amputations, although the exact numbers vary by study and should be interpreted with caution. Anxiety and sleep quality often improve when patients feel confident their treatment is delivering benefit, so faster, more reliable healing matters for daily life. The review has real limitations: the included trials were often small, used different suction settings and dressing schedules, and were at risk of bias, so the findings are promising rather than definitive.

• Negative pressure wound therapy (NPWT) uses a sealed dressing and gentle suction pump to remove wound fluid, reduce swelling, and encourage blood flow to help diabetic foot ulcers heal.
• This meta-analysis pooled multiple trials comparing NPWT with standard wound care and found better healing and fewer major amputations with NPWT.

Diabetic foot ulcers — open wounds on the feet that are slow to heal in people with diabetes — are a leading cause of amputation, so finding better ways to prevent and treat them matters enormously. This article, published in the Journal of Visualized Experiments (a journal that publishes step-by-step demonstration videos of laboratory and clinical methods), explains the expanding role of nurses in three connected areas: stopping ulcers before they start, managing wounds when they do occur, and using digital tools to monitor feet remotely. Rather than reporting a single clinical trial with hundreds of patients, it presents a practical, protocol-style overview of nursing techniques — for example structured foot inspections, correct offloading (taking pressure off the wound), cleaning and dressing wounds, and teaching patients self-care. It also describes digital monitoring approaches such as smartphone photography, temperature-sensing mats, and wearable sensors that can flag early warning signs like rising skin temperature or new redness before an ulcer becomes serious. The key message is that consistent, skilled nursing care and early detection can substantially reduce ulcer formation and complications, and that nurses are often the frontline providers who catch problems first. The article notes that these methods are well suited to busy clinics and to patients managing their feet at home between visits. Because this is a methods and review-style paper rather than a randomized trial, it does not provide definitive proof of how much these approaches reduce amputation rates in every setting, and results can vary depending on patient resources, training, and follow-up. Still, it supports the growing view that organized nursing and digital follow-up should be standard parts of diabetic foot care.

• Diabetic foot ulcers are a major cause of lower-limb amputation, and nurses play a central role in preventing and managing them.
• The article reviews three areas: preventing ulcers, managing open wounds, and using digital tools to monitor feet remotely.

This study reports on a complex case in which doctors treated a deep, infected heel wound in a 58-year-old woman with insulin-dependent diabetes. Diabetic foot ulcers are hard to heal when the arteries in the leg are narrowed or blocked, and heel wounds are especially difficult because that area bears the body's weight and has little soft tissue to spare. The patient had a chronic infected ulcer on the sole of her heel with exposed heel bone (calcaneus) and suspected bone infection (osteomyelitis). Imaging showed blood was still reaching the foot through one artery (the dorsalis pedis), but the main artery to the back of the leg and the arteries to the sole of the foot were chronically blocked. Because the planned reconstructive surgery — a reverse sural flap, which borrows skin and tissue from the calf to cover the heel — needs strong blood flow, the surgeons first performed a lateral plantar angioplasty to open a blocked artery in the sole of the foot with a balloon. This case report suggests that carefully restoring blood flow even when some flow is still present may help support complex heel reconstruction and avoid amputation. However, this is a single patient report, so it does not prove the approach works for everyone; larger studies are needed, and outcomes may differ in other patients.

• Heel ulcers are especially challenging because the heel bears weight and has little cushioning tissue to cover exposed bone after surgery.
• Doctors used balloon angioplasty to open a blocked sole artery before a reverse sural flap to cover the heel.

This clinical trial focuses on diabetic foot ulcers (DFUs), a common and serious complication of diabetes that can lead to amputation if not treated effectively. The study is comparing two advanced wound-healing approaches: a high-purity type-I collagen-based skin substitute and an acellular intact fish skin matrix, both used alongside standard wound care. The trial is currently recruiting participants and will take place at multiple centers in Dhaka, Bangladesh, and in Mandya and Mysore, India. The goal is to see which treatment leads to better healing outcomes for patients. This research matters because DFUs are notoriously difficult to treat, and new options are urgently needed to prevent amputations and improve quality of life. In China, where DFU rates are rising due to increasing diabetes prevalence, specialists are also exploring advanced biologics and skin substitutes, making this trial relevant to global treatment trends.

• The trial compares two promising skin substitutes—collagen-based and fish skin matrix—both combined with standard care, to see which heals diabetic foot ulcers better.
• Patients with DFUs that haven't responded to standard treatments may benefit from these advanced therapies, which aim to speed healing and reduce amputation risk.

This study is testing a new treatment for chronic, hard-to-heal wounds on the legs and feet caused by poor blood flow (ischemia) and diabetes. The treatment, called Transverse Tibial Bone Transport (TTT), involves a surgical procedure that uses a device to slowly move a piece of bone in the lower leg, which may help grow new blood vessels and improve healing. The trial is currently recruiting participants and is taking place in Jacksonville, United States. It will evaluate how well wounds heal and whether limbs can be saved in patients who have few other options. This research matters because diabetic foot ulcers are a leading cause of amputation, and many patients do not respond to standard treatments like wound care, offloading, and medications. In China, TTT and similar bone transport techniques are already used at some specialist centers, so this trial may confirm their benefits and help make them more widely available. The study uses a device called Biodynamik XT3.

• The trial is testing a surgical technique called Transverse Tibial Bone Transport (TTT) that may stimulate new blood vessel growth in the leg, potentially healing wounds that haven't responded to other treatments.
• For patients with chronic diabetic foot ulcers and poor circulation, this approach could offer a chance to avoid amputation, but it is still under study to confirm its safety and effectiveness.

Negative pressure wound therapy, often called vacuum-assisted healing, is a widely used treatment for difficult wounds, including diabetic foot ulcers. It works by placing a sealed foam dressing over the wound and applying gentle suction, which removes excess fluid and helps new tissue grow. Although doctors have used this therapy for decades, no one had mapped how the research behind it has grown, who is collaborating, and which topics are gaining attention. This study analyzed 4,063 scientific articles and reviews about negative pressure wound therapy, selected from 5,957 records in a major research database. The researchers used special software to track publication trends, collaborations between countries and institutions, and common keywords over time. They found that research output increased sharply after 2004, with the United States and China producing the most studies, while European and U.S. institutions were central in collaboration networks. The main focus of research shifted from basic mechanisms like pressure and blood flow toward practical topics such as wound dressings, surgical-site infections, diabetic foot ulcers, and treatment effectiveness. This matters because it shows that diabetic foot ulcers are now a top priority in wound-care research, and it highlights the need for more large, multi-center clinical trials and international teamwork. A key limitation is that this was a bibliometric analysis, meaning it studied patterns in publications rather than measuring how well the treatment actually works in patients; it also only included articles from one database, so some research may have been missed.

• Negative pressure wound therapy uses gentle suction to remove fluid and help difficult wounds, including diabetic foot ulcers, heal.
• This study reviewed 4,063 articles and found research grew rapidly after 2004, with the U.S. and China producing the most publications.

For people with diabetes, a foot infection that reaches the heel bone is one of the most feared complications, especially when the leg's blood supply is poor and the bacteria are resistant to many antibiotics. This case report describes a new approach that combines several treatments to save the leg. Doctors treated a 53-year-old man with type 2 diabetes, kidney disease, poor circulation (chronic limb-threatening ischemia), and a multidrug-resistant infection in his heel bone. They first improved blood flow with a procedure to open blocked arteries, then removed infected bone, and used antibiotic beads made of calcium sulfate placed directly into the bone defect. These beads release high doses of antibiotics right where the infection is. The man also received negative-pressure wound therapy (a vacuum dressing), hyperbaric oxygen therapy (breathing oxygen in a pressurized chamber), and careful offloading (keeping weight off the foot). After 14 months, the wound was completely healed, the infection did not return, and the man could walk without pain using special footwear. This is just one case, so more research is needed to confirm if this works for others. Still, it shows that even severe heel bone infections with poor circulation and resistant bacteria might be treatable with a team approach, potentially avoiding amputation.

• Heel bone infection with poor circulation and resistant bacteria is a major amputation risk; this case shows a limb-saving approach.
• Treatment combined blood flow restoration, bone cleaning, antibiotic beads, vacuum therapy, oxygen therapy, and offloading.

Necrotizing fasciitis is a rare but life-threatening infection that can destroy skin, fat, and muscle. In people with diabetes, foot infections are already serious, and when they are caused by bacteria resistant to many antibiotics, doctors may have few options besides amputation. This case report describes a single patient with diabetic foot necrotizing fasciitis caused by extensively drug-resistant Acinetobacter baumannii, a bacterium that is very hard to treat. Doctors used an integrative treatment approach that combined surgery, antibiotics, and other therapies to save the limb. The report details how they managed the infection and avoided amputation. The key finding is that limb salvage was possible even with this dangerous infection. This suggests that a coordinated, multi-pronged approach may help some patients keep their foot. However, because it is a single case, the results may not apply to everyone, and more research is needed.

• Diabetic foot infections with extensively drug-resistant bacteria are a growing challenge, often leading to amputation.
• This case report describes one patient who avoided amputation through an integrative treatment approach.

Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation. This expert consensus from the Chinese Geriatrics Society aims to standardize the use of bone cement as a first step in treating these wounds, followed by skin grafts or flaps. The consensus is based on a review of existing studies and clinical experience, not a new clinical trial. It provides recommendations for how to apply bone cement to prepare the wound bed for healing. Bone cement is a medical material that can fill and protect the wound while delivering antibiotics. The goal is to improve outcomes and reduce amputations. Patients should discuss this approach with their doctor to see if it is suitable for their situation.

• Bone cement is a medical material that can be placed in diabetic wounds to fight infection and create a healthy base for skin grafts.
• This 2026 expert consensus from China provides guidelines for doctors on how to use bone cement effectively in diabetic wound treatment.

Chronic wounds that are hard to heal, like diabetic foot ulcers, are a major problem for patients and healthcare systems. This review looked at whether a specific type of collagen, called high-purity type I collagen, can help these wounds heal. The authors gathered and analyzed existing studies on this topic. They found that using high-purity type I collagen can lead to more wounds healing completely compared to standard treatments. For example, one study showed that 45% of wounds treated with this collagen healed completely, compared to 25% with standard care. Other benefits included faster healing times and less need for amputations. This suggests that high-purity type I collagen could be a valuable addition to wound care, especially for wounds that haven't responded to other treatments. However, the review also notes that more high-quality research is needed to confirm these findings and understand the best ways to use this treatment.

• High-purity type I collagen is a material that can be applied to hard-to-heal wounds like diabetic foot ulcers to promote healing.
• A review of studies found that this collagen may help more wounds heal completely compared to standard treatments, with some studies showing a 20% improvement.

For people with advanced diabetic foot infections, doctors sometimes have to amputate part of the foot to save the patient's life. This case report describes a middle-aged man with a severe diabetic foot infection that had spread deep into the foot. Rather than amputating below the knee, surgeons performed a proximal midfoot amputation, removing only the front part of the foot while preserving the heel and ankle. This approach allowed the patient to keep his own leg and later walk using a specially fitted prosthesis. The report details the surgical steps and the patient's recovery over several months. The key finding is that this less extensive amputation can be a functional alternative to major amputation in selected cases. It offers a chance to maintain mobility and independence without losing the entire lower leg. However, because this is a single case report, the results may not apply to everyone; more research is needed to confirm when this technique works best.

• A proximal midfoot amputation removes only the front of the foot, preserving the heel and ankle for better balance and walking.
• This case shows a patient with severe diabetic foot infection avoided below-knee amputation and walked again with a prosthesis.

This article reviews how artificial intelligence (AI) is being used to improve wound care, especially for chronic wounds like diabetic foot ulcers, venous leg ulcers, and pressure ulcers. The authors looked at current and emerging AI tools, such as software that analyzes wound images, detects infections, predicts how wounds will progress, and helps doctors make decisions. They also discussed how AI can work with mobile health apps and wearable devices for remote monitoring and telehealth. The main findings suggest that AI can make wound assessment more accurate and efficient, potentially leading to better clinical outcomes and cost savings. However, the article highlights challenges like data quality, algorithm bias, ethical issues, and regulatory hurdles that need to be solved. The authors advise that clinicians can use AI safely if they understand its limits, but more research is needed. Overall, this review points to AI as a promising tool to enhance wound care, but it is not yet a replacement for human expertise.

• AI tools can analyze wound images and detect infections with high accuracy, helping clinicians assess diabetic foot ulcers more efficiently.
• Predictive modeling with AI can forecast wound healing outcomes, allowing earlier intervention for patients at risk of delayed healing.

This study looked at the safety of a special wound dressing made from sheep stomach tissue, called ovine forestomach matrix (OFM), used to help heal different types of wounds. The researchers collected data from 474 wounds in a registry across multiple medical centers to see how many complications occurred. The findings showed that the overall complication rate was low, with only about 12.4% of wounds experiencing any issue, and most of these were minor and could be treated easily. The most common problem was a small amount of fluid buildup or incomplete healing, which could often be managed with extra care. This is important because for people with diabetic foot ulcers, having a safe and effective treatment option can help save limbs and improve quality of life. However, the study did not directly compare OFM to other dressings, and more research will be needed to see how well it works in different situations.

• This study found that ovine forestomach matrix, a wound dressing made from sheep stomach, had a low complication rate of about 12.4% across 474 wounds.
• Most complications were minor and treatable, such as fluid buildup or incomplete healing, and serious problems were very rare.

Venous leg ulcers and diabetic foot ulcers are chronic wounds that share underlying problems with blood flow and pressure on the skin. This review examined commonalities between the two conditions to propose a unified management framework. The authors analyzed existing research and clinical knowledge to identify overlapping vascular and mechanical factors. They found that both types of ulcers are often driven by poor circulation and abnormal pressure, which can impair healing. The unified framework suggests that combined assessment and treatment of these factors could improve outcomes. This approach may lead to more consistent and effective care for patients with different ulcer types. Because it is a review, it does not include new patient data but synthesizes current evidence. The main limitation is that the framework needs validation in clinical practice.

• Venous leg ulcers and diabetic foot ulcers share common causes, including poor blood flow and pressure issues.
• A unified management framework may help doctors treat both types of ulcers more consistently.

Diabetes-related foot ulcers are a serious complication where wounds on the foot do not heal, sometimes leading to amputation. Even when blood flow is restored through a procedure called revascularization, many ulcers still fail to heal. This review looked at why this 'patency-to-healing gap' exists by examining scientific studies on the topic. The authors found that successful revascularization does not guarantee healing because other factors, such as infection, pressure on the foot, and poor nutrition, play a major role. They also highlighted that the quality of the newly restored blood flow, especially in tiny vessels, is crucial. The review suggests that a comprehensive approach, including infection control, offloading pressure, and optimizing wound care, is essential. However, this is a narrative review, not a primary study, so it lacks direct patient data. For patients, this means that even after successful surgery to restore blood flow, ongoing multidisciplinary care is vital for wound healing.

• Revascularization restores blood flow but does not guarantee ulcer healing; a 'gap' often remains due to other factors.
• Ongoing infection, pressure on the foot, and nutritional status are critical for healing even after successful revascularization.

This clinical trial is studying an investigational wound gel called VES-0-D for the treatment of mild to moderate diabetic foot ulcers. The trial aims to determine if this gel is more effective than standard wound care in promoting healing. The study is currently recruiting participants at several sites in Belgium, and it will compare wound area reduction over an 8-week treatment period. Participants will receive the gel or standard care every 3-4 days, visit the clinic weekly for assessments, and keep a diary of their symptoms. This research is important because diabetic foot ulcers are a serious complication of diabetes that can lead to infections and even amputation if not treated effectively. In China, diabetic foot ulcer management is a growing concern, and findings from this trial could inform future treatment options and best practices.

• Tests a new wound gel (VES-0-D) versus standard care for diabetic foot ulcers.
• The trial is actively recruiting in Belgium, with sites in Bonheiden, Mechelen, Liège, and Leuven.

This study explores how the community of microbes (microbiome) on a diabetic foot ulcer and the patient's own gene activity (transcriptome) interact to affect wound healing. Researchers analyzed samples from diabetic foot ulcer patients to see which bacteria are present and which host genes are turned on or off. They found that certain bacteria, like Staphylococcus and Pseudomonas, are more common in non-healing wounds, and these are linked to increased inflammation and reduced tissue repair activity in the host. The study suggests a framework where the wound environment, microbes, and host response together determine healing outcomes. This matters because it points to potential new treatments that target both microbes and the host's immune response. However, the study is limited by its small sample size and the complexity of the interactions, so more research is needed before clinical recommendations can be made.
