High Morbidity

Diabetic foot ulcers (DFUs) are a serious complication in diabetic patients and lead to high morbidity and mortality. Numerous dressings have been developed to facilitate wound healing of DFUs. This study investigated the wound healing efficacy of silver-releasing foam dressings versus silver-containing cream in managing outpatients with DFUs. Sixty patients with Wagner Grade 1 to 2 DFUs were recruited. The treatment group received silver-releasing foam dressing (Biatain® Ag Non-Adhesive Foam dressing; Coloplast, Humlebaek, Denmark). The control group received 1% silver sulfadiazine (SSD) cream. The ulcer area in the silver foam group was significantly reduced compared with that in the SSD group after four weeks of treatment (silver foam group: 76.43 ± 7.41%, SSD group: 27.00 ± 4.95%, p < 0.001). The weekly wound healing rate in the silver foam group was superior to the SSD group during the first three weeks of treatment (p < 0.05). The silver-releasing foam dressing is more effective than SSD in promoting wound healing of DFUs. The effect is more pronounced in the initial three weeks of the treatment. Thus, silver-releasing foam could be an effective wound dressing for DFUs, mainly in the early period of wound management.

Cycle Arrest

Merkel cell carcinoma (MCC) is an often-lethal skin cancer with increasing incidence and limited treatment options. Although immune checkpoint inhibitors (ICI) have become the standard of care in advanced MCC, 50% of all MCC patients are ineligible for ICIs, and amongst those treated, many patients develop resistance. There is no therapeutic alternative for these patients, highlighting the urgent clinical need for alternative therapeutic strategies. Using patient-derived genetic insights and data generated in our lab, we identified aurora kinase as a promising therapeutic target for MCC. In this study, we examined the efficacy of the recently developed and highly selective AURKA inhibitor, AK-01 (LY3295668), in six patient-derived MCC cell lines and two MCC cell-line-derived xenograft mouse models. We found that AK-01 potently suppresses MCC survival through apoptosis and cell cycle arrest, particularly in MCPyV-negative MCC cells without RB expression. Despite the challenge posed by its short in vivo durability upon discontinuation, the swift and substantial tumor suppression with low toxicity makes AK-01 a strong potential candidate for MCC management, particularly in combination with existing regimens.

The aim of our study was to analyze the influence of radiographic arterial calcification (RAC) on clinical outcomes and wound healing in patients with diabetic foot ulcers complicated by osteomyelitis treated by surgery. We analyzed retrospectively the clinical records of 102 patients with diabetic foot osteomyelitis who underwent surgery at a specialized diabetic foot unit between January 2014 and December 2016. The clinical data of evolution until its complete epithelialization and a follow-up 1 year were reviewed, and after reviewing the radiological images, patients were classified into 2 groups: those with RAC and those without RAC. We analyzed several clinical features in both groups. The presence of RAC was associated with a greater time of healing (10.68 ± 7.24 vs 8.11 ± 4.50 weeks; P = .029) and shorter time to recurrence and reulceration (13.30 ± 9.25 vs 18.81 ± 11.63 weeks; P = .036). However, this association was not found for patients with mild and moderate peripheral artery disease (PAD), whose time of healing was 8.97 ± 4.51 weeks compared to 9.16 ± 6.39 weeks for patients without PAD; P = .864. The time of healing of diabetic foot ulcers complicated by osteomyelitis treated by surgery can be negatively affected by the presence of RAC even more than by the presence of mild and moderate ischemia. The presence of RAC may offer clinical guidance at the level of primary care though this would need thorough validation in future studies.

Abstract Background: Dysregulation of cell cycle progression is one of the common features of human cancer cells, however, its mechanism remains unclear. This study aims to clarify the role and the underlying mechanisms of Roquin1 in cell cycle arrest induction in breast cancer.Methods: Public cancer databases were analyzed to identify the expression pattern of Roquin1 in human breast cancers and the significant association with patient survival. Quantitative real-time PCR and western blots were performed to detect the expression of Roquin1 in breast cancer samples and cell lines. Cell counting, MTT assay, flow cytometry, and in vivo study were conducted to investigate the effects of Roquin1 on cell proliferation, cell cycle progression and tumor progression. RNA-sequencing was applied to identify the differential genes and pathways regulated by Roquin1. RNA immunoprecipitation assay, luciferase reporter assay, mRNA half-life detection, RNA affinity binding assay, and RIP-ChIP were used to explore the molecular mechanisms of Roquin1.Results: We showed that Roquin1 expression in breast cancer tissues and cell lines was inhibited, and the reduction in Roquin1 expression was associated with poor overall survival and relapse free survival of patients with breast cancer. Roquin1 overexpression inhibited breast cancer cell proliferation and induced G1/S cell cycle arrest without causing significant apoptosis. In contrast, knockdown of Roquin1 promoted breast cancer cell growth and cycle progression. Moreover, in vivo induction of Roquin1 by adenovirus significantly suppressed breast tumor growth and metastasis. Mechanistically, Roquin1 selectively destabilizing cell cycle–promoting genes, including Cyclin D1, Cyclin E1, cyclin dependent kinase 6 (CDK6) and minichromosome maintenance 2 (MCM2) through targeting the stem–loop structure in the 3’untranslated region (3’UTR) of mRNAs via its ROQ domain, leading to the downregulation of cell cycle–promoting mRNAs.Conclusions: Our findings demonstrated that Roquin1 was a novel breast tumor suppressor and could induce G1/S cell cycle arrest by selectively downregulating the expression of cell cycle–promoting genes, which might as a potential molecular target for breast cancer treatment.

Abstract: Diabetic foot ulcer (DFU) is still a health problem related to the extent amount of time in wound healing process hence increasing the treatment cost. Given any methods that are not sat-isfying, encourage the search of other methods that would increase the wound healing rate, in which hyperbaric oxygen therapy (HBOT) is amongst them. The DFU patient that receives HBOT shows a significant increase in angiogenesis process markedly by faster epithelialization and granulation process. This study was aimed to prove that HBOT could accelerate the wound healing process among DFU patients measured by wound size and depth of PEDIS score. This was a ran-domized controlled trial study, conducted at Surgery Department of Prof. Dr. R. D. Kandou Gen-eral Hospital from September 2018 to March 2019. There were 20 DFU patients divided into two groups, each of 10 patients. The control group received a holistic treatment, meanwhile the HBOT group received a holistic treatment added with the inclusion of HBOT. PEDIS score assessment of DFU in HBOT group was measured before and after the third HBOT session, meanwhile the con-trol group was measured on the first and the third day. The results showed that the difference in PEDIS score value was markedly found in HBOT group compared to the control group (2 vs. 0, P=0.001). Conclusion: HBOT could enhance the wound healing process in DFU patients based on the declined PEDIS score.Keywords: HBOT, PEDIS score, diabetic foot ulcerAbstrak: Ulkus kaki diabetik (UKD) masih merupakan masalah kesehatan terkait proses penyembuhan lama sehingga biaya pengobatan meningkat. Belum adanya metode penanganan yang memuaskan, mendorong pencarian metode percepatan penyembuhan luka, salah satunya ialah terapi oksigen hiperbarik (TOHB). Penderita UKD yang menjalani tambahan TOHB diketahui mengalami peningkatan proses angiogenesis yang menghasilkan proses epitelialisasi dan granulasi yang lebih cepat. Tujuan penelitian ialah untuk membuktikan bahwa TOHB dapat mempercepat proses penyembuhan UKD, dinilai berdasarkan ukuran dan kedalaman luka melalui skor PEDIS. Penelitian ini menggunakan randomized controlled trial dan dilaksanakan di Bagian Bedah RSUP Prof. Dr. R.D. Kandou Manado sejak September 2018 sampai dengan Maret 2019. Subyek penelitian sebanyak 20 penderita UKD, dibagi dalam dua kelompok, masing-masing 10 penderita. Kelompok kontrol menjalani penanganan holistik UKD, sedangkan kelompok TOHB menjalani penanganan holistik UKD dengan TOHB. Penilaian skor PEDIS terhadap UKD pada kelompok TOHB dilakukan sebelum dan sesudah TOHB sesi ke-3, sedangkan pada kelompok kontrol dilakukan penilaian pada hari ke-1 dan hari ke-3 sesudahnya. Hasil penelitian mendapatkan bahwa perubahan skor PEDIS yang terjadi antara kedua pengukuran terlihat lebih besar pada kelompok TOHB dibandingkan kelompok kontrol (2 vs 0, P=0,001). Simpulan. TOHB mempercepat proses penyembuhan UKD dinilai dari penurunan skor PEDIS.Kata kunci: TOHB, skor PEDIS, ulkus kaki diabetik
