Mesenchymal stem cells (MSCs) are stem cells with the potential ability to differentiate into various cells and the ability to self-renew and resemble fibroblasts. These cells can adhere to plastic to facilitate the culture process. MSCs can be used in research into tissue biotechnology and rejuvenation medicine. MSCs are also beneficial in recipient tissue and differentiate as a breakthrough strategy through paracrine activity. Many databases have shown MSC-based treatment can be beneficial in the reduction of osteogenesis induced by senescence. In this article, we will discuss the potential effect of MSCs in senescence cells related to osteogenesis.

Acute kidney injury (AKI) is associated with a worse prognosis in coronavirus disease 2019 (COVID-19) patients. Identification of AKI, particularly in COVID-19 patients, is important for improving patients’ management. The study aims to assess risk factors and comorbidities of AKI in COVID-19 patients. We systematically searched PubMed and DOAJ databases for relevant studies involving confirmed COVID-19 patients with data on risk factors and comorbidities of AKI. The risk factors and comorbidities were compared between AKI and non-AKI patients. A total of 30 studies involving 22385 confirmed COVID-19 patients were included. Male (OR: 1.74 (1.47, 2.05)), diabetes (OR: 1.65 (1.54, 1.76)), hypertension (OR: 1.82 (1.12, 2.95)), ischemic cardiac disease (OR: 1.70 (1.48, 1.95)), heart failure (OR: 2.29 (2.01, 2.59)), chronic kidney disease (CKD) (OR: 3.24 (2.20, 4.79)), chronic obstructive pulmonary disease (COPD) (OR: 1.86 (1.35, 2.57)), peripheral vascular disease (OR: 2.34 (1.20, 4.56)), and history of nonsteroidal anti-inflammatory drugs (NSAID) (OR: 1.59 (1.29, 1.98)) were independent risk factors associated with COVID-19 patients with AKI. Patients with AKI presented with proteinuria (OR: 3.31 (2.59, 4.23)), hematuria (OR: 3.25 (2.59, 4.08)), and invasive mechanical ventilation (OR: 13.88 (8.23, 23.40)). For COVID-19 patients, male gender, diabetes, hypertension, ischemic cardiac disease, heart failure, CKD, COPD, peripheral vascular disease, and history of use of NSAIDs are associated with a higher risk of AKI.

Background: The symptoms of nephrotic syndrome include severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Renal biopsy is essential to identify the histological subtype, which guides therapy and prognosis. Early diagnosis and treatment are crucial to prevent the progression of kidney failure. We present a case of nephrotic syndrome secondary to focal segmental glomerulosclerosis (FSGS), complicated by severe anemia, hypercoagulability, and pressure ulcers. Case Presentation: A 25-year-old woman presented with progressive generalized edema for four months, which ultimately restricted her mobility and resulted in immobilization and a prolonged bedridden state. She reported a decrease in urine output and foamy urine for two months. On admission, vital signs were stable. Physical examination revealed periorbital edema, pale conjunctiva, abdominal distension with striae and shifting dullness, non-pitting edema in both lower extremities and the left upper limb, and a gluteal wound with erythematous macules. Laboratory findings revealed severe normocytic normochromic anemia, hypoalbuminemia, hypercholesterolemia, and nephrotic-range proteinuria. Peripheral smear demonstrated anisopoikilocytosis, leucocytosis with immature granulocytes, and giant platelets. The direct Coombs test was positive and the d-dimer level was increased. Echocardiography revealed mild pericardial effusion, while abdominal ultrasound demonstrated gallbladder sludge with free peritoneal fluid. Doppler ultrasound of the left upper extremity showed no abnormalities, with no evidence of venous thrombus. Renal biopsy confirmed FSGS. She was diagnosed with nephrotic syndrome due to FSGS, complicated by severe anemia with a positive direct Coombs test, hypercoagulability, and pressure ulcers. Clinical improvement was achieved through the use of high dose corticosteroids, immunosuppressive therapy, and antihypertensive agents. Complete remission was achieved within six weeks. Conclusion: This case highlights the complexity of nephrotic syndrome caused by FSGS, where timely biopsy, immunosuppressive therapy, and supportive care were key to achieving remission and improving outcomes.

Introduction: Temporary non-tunneled catheters are necessary in patients with chronic kidney disease requiring acute hemodialysis care, and complications associated with these catheters, such as infection and thrombosis, represent the most important sources of morbidity. There are no studies available that suggest the optimum duration of their use before catheter exchange or removal. This study aimed to explore the duration of temporary catheter insertion before the occurrence of catheter-related infection and mechanical complications in hemodialysis patients. Methods: Systematic searches were conducted according to the PRISMA 2020 guidelines on four databases up to 1 May 2025 (PROSPERO: CRD420251069657). The study outcome was the occurrence time to catheter-related infection and mechanical complications (thrombosis, obstruction, and kinking, causing dysfunction, failure, or insufficient blood flow) in days, pooled using a single-arm meta-analysis. Mean and 95% confidence interval (CI) were used as the summary statistics. Results: Nine studies involving 1448 participants undergoing hemodialysis using temporary catheters were included. Incidence of infection ranged from 0.7 to 13.58 per 1000 catheter-days. The most common bacterium identified was Staphylococcus aureus and Pseudomonas aeruginosa. The pooled mean time to catheter-related infection from 298 catheters was 15.98 days (95% CI 10.47–21.50; I² = 97.73%). We also found that the pooled mean time to mechanical complications from 507 catheters was 6.69 days (95% CI 2.49–10.90; I² = 98.03%). Conclusion: Among patients who developed complications, the mean time from temporary catheter insertion was approximately two weeks to the occurrence of catheter-related infection and one week to mechanical complications. Our finding was consistent with the recommendation of the KDOQI guideline, which suggests limiting catheter duration to typically less than two weeks.
