Background and Objectives:
The timing of the reinstitution of warfarin after cesarean section (CS) delivery was not adequately addressed in the literature. This study aims to evaluate the risks of early versus late initiation of warfarin post-CS in patients with mechanical heart valves.
Methods:
This randomized, open-label cohort study included 114 pregnant women with mechanical heart valves planned to be delivered by CS at or after 28 weeks of gestation.Patients were randomly divided into two groups: Day-2-group, where warfarin was started on day 2, and Day-5-group, where warfarin was started on day 5 after CS. Maternal postoperative bleeding complications, mechanical valve thrombosis, need for blood transfusion or reoperation, and maternal mortality were identified.
Results:
Ten women (8.8%) had 11 bleeding complications, of whom 2 patients (20%) had intraperitoneal hemorrhage (none in Day-2-group and 2 in Day-5-group), 3 patients (30%) had subcutaneous hematoma (none in Day-2-group and 3 in Day-5-group), and 6 patients (60%) had sub-rectus hematoma (3 in Day-2-group and 3 in Day-5-group). No mechanical valve thrombosis, other thromboembolic events, or in-hospital maternal mortality were reported.
Conclusion
Despite the small number of events, the bleeding risk was lower in the group with early post-CS warfarin introduction than in the group with late warfarin introduction in patients with prosthetic heart valves.

Traumatic posterior atlantoaxial dislocation (TPAD) without an associated fracture is a rare and challenging spinal injury. This PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-compliant case-based systematic review and meta-analysis aimed to comprehensively explore TPAD, covering clinical presentation, diagnosis, treatment, and clinical and radiological outcomes. Following the presentation of a case of TPAD without an associated fracture, we conducted a systematic search of electronic databases, including Scopus, PubMed, and Web of Science, from inception through October 2023, without language restrictions. Cases involving dislocations due to congenital anomalies or inflammatory processes were excluded. The search yielded 31 eligible cases of TPAD without an associated fracture. The majority (81%) of the cases were males, with traffic accidents being the leading cause (87%). Notably, 52% of the cases presented without any neurological deficits. Regarding treatment approaches, 23% of the cases were managed through closed reduction alone, 32% required fusion following closed reduction, and 45% underwent open reduction and fusion. A time delay exceeding 7.5 days was associated with a significantly higher risk of closed reduction failure (odds ratio, 56.463; p =0.011). This review identified key management strategies for TRAD without fracture, informed by the available evidence. Optimal management entails prompt closed reduction under C-arm while monitoring neurological status once hemodynamic stability is achieved. Surgical fusion is indicated for cases with magnetic resonance imaging-confirmed transverse ligament rupture or residual instability. If closed reduction fails, open reduction and fusion should be carried out. Posterior C1–C2 screws fixation is the preferred fusion technique, providing high levels of safety and biomechanical stability.

Objective:
This study investigated the relationship of fetuin-A with coronary calcification, carotid atherosclerosis, and mortality risk in non-dialysis chronic kidney disease (CKD).
Methods:
The study included 135 adult patients with CKD at stages 3–5, who were divided into coronary artery calcification (CAC) and non-CAC groups. We excluded current smokers and individuals with diabetes mellitus, inflammatory conditions, liver diseases, acute kidney failure, chronic hemodialysis, and cancer. We conducted kidney function tests, complete blood counts, and measured serum levels of fetuin-A, tumor necrosis factor-alpha (TNF-α), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), total cholesterol (TC), total triglycerides (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. Cardiac spiral computed tomography was used to calculate the CAC score, employing the Agatston method. Carotid ultrasonography was performed to assess carotid intima-media thickness (CIMT) and to detect the presence of plaques.
Results:
CAC patients had considerably higher levels of TNF-α (p<0.001), IL-6 (p<0.001), hs-CRP (p=0.006), TC, TG, parathyroid hormone (PTH) (p<0.001) and phosphorus (p<0.001) than non-CAC patients. They also had significantly lower levels of fetuin-A (p<0.001). Fetuin-A was considerably lower in CKD subgroups as CKD progressed. Fetuin-A (p=0.046), age (p=0.009), TNF-α (p=0.027), IL-6 (p=0.005), TG (p=0.002), PTH (p=0.002), and phosphorus (p=0.004) were significant predictors of CAC. CAC and fetuin-A were strong predictors of all-cause mortality and cardiovascular (CV) mortality. Fetuin-A was a significant predictor of CIMT (p=0.045).
Conclusion
Fetuin-A reliably predicted CAC and CIMT. Fetuin-A and CAC emerged as significant risk factors for all-cause and CV mortality in non-dialysis CKD.

BACKGROUND:
Skin alterations are among the most prominent signs of aging, and they arise from both intrinsic and extrinsic factors that interact and mutually influence one another. The use of D-galactose as an aging model in animals has been widely employed in anti-aging research. Adipose tissue-derived mesenchymal stem cells (Ad-MSCs) are particularly promising for skin anti-aging therapy due to their capacity for effective re-epithelization and secretion of various growth factors essential for skin regeneration. Accordingly, we aimed to examine the potential utility of Ad-MSCs as a therapy for skin anti-aging.
METHODS:
In this study, we isolated and characterized adipose-derived mesenchymal stem cells (Ad-MSCs) from the epididymal fat of male Sprague Dawley rats. We assessed the in vitro differentiation of Ad-MSCs into epidermal progenitor cells (EPCs) using ascorbic acid and hydrocoritsone. Additionally, we induced skin aging in female Sprague Dawley rats via daily intradermal injection of D-galactose over a period of 8 weeks. Then we evaluated the therapeutic potential of intradermal transplantation of Ad-MSCs and conditioned media (CM) derived from differentiated EPCs in the D-galactose-induced aging rats. Morphological assessments, antioxidant assays, and histopathological examinations were performed to investigate the effects of the treatments.
RESULTS:
Our findings revealed the significant capability of Ad-MSCs to differentiate into EPCs. Notably, compared to the group that received CM treatment, the Ad-MSCs-treated group exhibited a marked improvement in morphological appearance, antioxidant levels and histological features.
CONCLUSIONS
These results underscore the effectiveness of Ad-MSCs in restoring skin aging as a potential therapy for skin aging.

Purpose:
Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility.
Materials and Methods:
Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological Association [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field.
Results:
The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/ uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the responses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identified where no guidelines are available.
Conclusions
This study is the largest global survey performed to date on the clinical management of varicocele for male infertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical practice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.
