Inhibition of the NLRP3 inflammasome enhances lifetime in dog murine label of Hutchinson-Gilford Progeria.
There is also emerging evidence on the use of vitamin D supplementation for the treatment of hard-to-heal wounds. More research is needed to understand the correlation between vitamin D and hard-to-heal wounds.
Research suggests a correlation between low vitamin D levels and hard-to-heal wounds. However, it is not clear if the relationship is causal or only correlational. click here There is also emerging evidence on the use of vitamin D supplementation for the treatment of hard-to-heal wounds. More research is needed to understand the correlation between vitamin D and hard-to-heal wounds.
To compare consultations carried out via video with those performed in person for patients with painful, hard-to-heal ulcers, with a focus on ulcer pain and pain treatment. A further aim was to investigate predictors for pain and pain treatment.

This was a register-based, quasi-experimental study based on data from the Swedish Registry of Ulcer Treatment (RUT). A total of 100 patients with hard-to-heal ulcers diagnosed via video consultation were compared with 1888 patients diagnosed in person with regard to pain assessment, intensity and treatment. Ulcer pain intensity was assessed by the visual analogue scale (VAS). Normally distributed variables (age, VAS) were compared between consultation groups using Student's t-test. Non-normally distributed variables (ulcer size, ulcer duration) were compared using the Mann-Whitney U-test, except for healing time, which was analysed with a log-rank test. Categorical variables (gender, ulcer aetiology and prescribed analgesics) were compared using Pearson's chi-squients with hard-to-heal ulcers suffer from high-intensity ulcer pain, with a discrepancy between pain and pain relief. Further well-designed randomised controlled studies are necessary to understand how best to deploy telemedicine in ulcer pain treatment.
To identify, assess and treat ulcer pain is equally possible via video as by in-person consultation. The results of this study confirm that patients with hard-to-heal ulcers suffer from high-intensity ulcer pain, with a discrepancy between pain and pain relief. Further well-designed randomised controlled studies are necessary to understand how best to deploy telemedicine in ulcer pain treatment.
To describe the rates of healing, major amputation and mortality after 12 months in patients with a new diabetic foot ulcer (DFU) and their care in a French diabetic foot service (DFS).

A prospective single-centre study including patients from March 2009 to December 2010. The length of time to healing, minor amputation, major amputation and mortality rate after inclusion were analysed using the Kaplan-Meier method.

Some 347 patients were included (3% lost to follow-up), with a median follow-up (IQR) of 19 (12-24) months. The mean (SD) age was 65±12 years, 68% were male, and the median duration of the ulcer was 49 (19-120) days. Complications of the DFU were ischaemia (70%), infection (55%) and osteomyelitis (47%). Of the patients, 50% were inpatients in the DFS at inclusion (median duration of hospitalisation 26 (15-41) days). The rate of healing at one year was 67% (95% confidence interval (CI) 61-72); of major amputation 10% (95% CI 7-17); of minor amputation 19% (95% CI 14-25), and the death rate was 9% (95% CI 7-13). Using an adjusted hazard ratio, the predictive factors of healing were perfusion and the area of the wound. The risk factors for a major amputation were active smoking and osteomyelitis. The risk factors for mortality were perfusion and age.

This study confirms the need to treat DFUs rapidly, in a multidisciplinary DFS.

Pressure ulcers (PUs) are a major healthcare problem, commonly associated with older people, patients who are bedbound and patients with diabetes. The impact of PUs can decrease patients' quality of life, and lead to high morbidity and mortality rates. In this study, we aimed to describe a novel PU model that simulates pressure ulcers in humans to provide a research tool for new drug testing.

Diabetes was induced using streptozocin in 75 adult Sprague Dawley rats. To create the PU, skin was sandwiched between two magnets, one of them implanted below the panniculus carnosus muscle and the other above the skin. The model was tested on nondiabetic rats and diabetic rats, each with pressure ulcers, compared to nondiabetic rats with excisional wounds.

Results showed that the PU model in diabetic (p-value<0.000001) and non-diabetic rats (p-value<0.05) exhibited significantly delayed healing (no healing over 21 days) compared with the excisional wound that was completely healed by day 21.

Diabetic rats showed significant changes in intact skin compared with non-diabetic rats, as well as a significant delay in the healing process compared with the non-diabetic group. By effectively impairing the skin contraction otherwise seen in the rats, and thereby delaying healing and making it similar to that seen in hard-to-heal PUs in humans, this model provides an effective tool for wound healing research.

Little is known about the efficacy of products aiming to prevent radiodermatitis, which affects between 90-95% of women with breast cancer. The use of antioxidants is promising, however, there is a lack of evidenceon their effectiveness. Here, the authors present a clinical trial protocol to evaluate the effects of applying a cream containing nanoparticles with vitamin E to prevent radiodermatitis in patients with breast cancer.

The protocol recommends that 108 women with breast cancer, receiving radiotherapy, are included in this triple-blinded, randomized, controlled study at an oncology hospital. Patients will be divided in three groups of 36 individuals each group A will receive a cream with lipid nanoparticles and vitamin E, group B will receive a cream without nanoparticles nor vitamin E, and group C will receive a cream with nanoparticles without vitamin E. The primary endpoints will evaluate the incidence, degree, and time of onset of radiodermatitis. The secondary endpoints will focus on the qualotherapy treatment to two weeks after the last session. This protocol was approved by the research ethics committee of the institutions involved and registered on an international trials database.Aim To investigate whether kaempferol exhibited protective effects on osteoarthritis chondrocytes by modulating the XIST/miR-130a/STAT3 axis. Methods qRT-PCR and western blot assays were used for gene and protein determination. Dual luciferase reporter and RNA immunoprecipitation assays were employed to study the interaction between miRNA and lncRNA or genes. Results Kaempferol decreased proinflammatory cytokine production and extracellular matrix degradation in C28/I2 cells. Additionally, kaempferol ameliorated XIST expression and enhanced miR-130a expression. XIST interacted with miR-130a, and STAT3 was identified as a target of miR-130a. Knockdown of XIST expression suppressed proinflammatory cytokine production and extracellular matrix degradation in C28/I2 cells. Overexpression of STAT3 rescued the effects of XIST knockdown. Conclusion Kaempferol inhibited inflammation and extracellular matrix degradation by modulating the XIST/miR-130a/STAT3 axis in chondrocytes.Advanced esophago-gastric (OG) adenocarcinomas have a high mortality rate and new therapeutic options are urgently required. Despite recent advances in understanding the molecular characteristics of OG cancers, tumor heterogeneity poses a challenge in developing new therapeutics capable of improving patient outcomes. Consequently, chemotherapy remains the mainstay of systemic treatment, with the HER2 being the only predictive biomarker routinely targeted in clinical practice. Recent data indicate that immunotherapy will be incorporated into first-line chemotherapy, but further research is required to refine patient selection. This review will summarize the clinical strategies being evaluated to utilize our knowledge of predictive biomarkers with reference to novel therapeutics, and discuss the barriers to implementing precision oncology in OG adenocarcinoma.Aim The prognosis of resectable pancreatic cancer patients with the same stage of disease is highly variable. The purpose of this study is to establish a scoring system for preoperative screening of resectable patients. Materials & methods The clinical information and laboratory tests of 105 resectable patients with pancreatic cancer were enrolled and analyzed. Results The consistency of clinical stage and pathological stage was poor (κ = 0.193; p less then 0.003). We performed a comprehensive scoring system with KRAS mutations in circulating tumor DNA (mutKRAS ctDNA) for the resectable patients. Patients with higher scores were more prone to early postoperative recurrence and poorer prognosis. Conclusion The scoring system can help preoperatively screen out resectable patients who are prone to early postoperative recurrence.Although statins are effective in treating high cholesterol, adverse effects do occur with their use. Efficacy and tolerability vary among statins in different ethnic groups. Indigenous Australians have a high risk for cardiovascular and kidney diseases. Prescribing statins to Indigenous Australians with multi-morbidity requires different strategies to increase efficacy and reduce their toxicity. Previous studies have reported that Indigenous Australians are more susceptible to severe statin-induced myopathies. However, there is a lack of evidence in the underlying genetic factors in this population. This review aims to identify inter-ethnic differences in the efficacy and safety of statins; major contributing factors accounting for any identified differences; and provide an overview of statin-induced adverse effects in Indigenous Australians.[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].[Figure see text].Background Serum uric acid (SUA) has been demonstrated as a risk factor for myocardial infarction (MI) and all-cause mortality; however, the impact of cumulative SUA (cumSUA) remains unclear. We aimed to investigate the association of cumSUA with MI risk and all-cause mortality, and to further explore the effects of SUA accumulation time course. Methods and Results The study enrolled 53 463 participants without a history of MI, and these participants underwent 3 examinations during 2006 to 2010. cumSUA from baseline to the third examination was calculated, multiplying mean values between consecutive examinations by time intervals between visits. Cox models estimated hazard ratios (HRs) and 95% CIs of MI and all-cause mortality for cumSUA quartiles, hyperuricemia exposure duration, and SUA accumulation time course. During a median follow-up of 7.04 years, 476 incident MIs and 2692 deaths occurred. In the fully adjusted model, a higher MI risk was observed in the highest cumSUA quartile (HR, 1.48; 95% CI, 1.10-1.
