Carotid artery stenting (CAS) is considered for patients with symptomatic carotid stenosis of 50% or greater. Following CAS, hemodynamic changes can alter the cerebral perfusion status. Furthermore, hypotension and bradycardia may occur due to the stimulation of carotid sinus baroreceptors. A more meticulous approach to these hemodynamic changes is required, especially in patients with bilateral carotid artery stenosis and concurrent multiple cerebrovascular stenoses. This report presents a case of posterior cerebral artery territory infarction that occurred after bilateral CAS.

Background: Identifying the risks related to the complications of electrical cardioversion (ECV) can alert the determinaton of rhythm control in patients with atrial fibrillation (AF). Methods: We retrospectively reviewed 1,058 patients who underwent ECV for persistent or long-standing persistent AF/atrial flutter (AFL) from multiple centers. Patients were classified into the no-complication (1,023 patients) and complication (35 patients) groups based on the following major complications: stroke and/or systemic embolism (SSE), myocardial infarction, major bleeding, implantation of cardiac implantable electronic devices, ventricular tachycardia/fibrillation, and death at 1 year follow-up after ECV. Results: Compared with the no-complication group, the complication group exhibited a higher proportion of female patients (37% vs. 22%), as well as a higher proportion of patients with older age (67 ± 11 vs. 61 ± 10 years), diabetes mellitus (DM) (49% vs. 24%), heart failure (HF) (49% vs. 30%), SSE (23% vs. 9%), high CHA 2 DS 2 -VASc (CV) score (3.6 ± 1.8 vs.2.2 ± 1.4), low left ventricular ejection fraction (LVEF) (50 ± 16% vs. 58 ± 21%), and high left atrial volume index (LAVI) (51 ± 26 vs. 40 ± 20 mL/m 2 ). Class I and III antiarrhythmics were less prescribed in the complication group than in the no-complication group (57% vs.76%). Univariate analysis for complications revealed age (≥ 65 years), female sex, DM, HF, SSE, LVEF (< 50%), LAVI (≥ 40 mL/m 2 ), CV score (≥ 3), bradycardia on Holter (< 60/min), and no antiarrhythmics as risk factors. Among these, multivariate analysis revealed clinical significance of female sex and SSE. Conclusion Female sex and a history of SSE were the most important risk factors of complications in patients with persistent or long-standing persistent AF/AFL who underwent ECV.

Purpose: Chemo-port insertion is performed by a radiologist or surgeon in an interventional radiology (IR) suite or an operating room (OR). The complication rate is approximately 3%–4%. However, there is still a lack of data for comparison when it is performed in different conditions such as IR suite and OR. Methods: This study is for the safety of adult cancer patients after chemo-port implantation by comparing postoperative complication types and rates in different places. Among 375 patients who underwent chemo-port implantation, 203 patients underwent chemo-port implantation by radiologists in an IR suite, and 172 patients underwent the procedure by general surgeons in an OR. In both groups, early and late mortality were investigated. Early and late complication types and rates were also compared, and our study results were compared to the literature. Results: Patients’ characteristics showed no differences. Mortality after the procedure was 39 in OR vs. 72 in IR (P < 0.01).Early mortality at 7 days was 1 in IR, no patient in OR (P = 0.36). Catheter problems did not show a statistical difference in these 2 groups (1.16% vs. 0.49%, P = 0.47). Venous thrombosis happened in 4 and 7 (2.33% vs. 3.45%, P = 0.13), and the central line bloodstream infection was in 5 patients and 6 patients (2.91% vs. 2.96 %, P = 0.98), respectively. Skin problems were 6 and 7 (3.49% vs. 3.45 %, P = 0.98). Port site infection happened in 6 patients in each group (3.49% vs. 2.96 %, P = 0.77). Conclusion Chemo-port implantation can be performed in OR or IR without difference in complication rates.

Phenylketonuria (PKU), an autosomal recessive genetic disorder, has been documented to exhibit over 950 distinct mutations. This condition primarily affects the metabolism of phenylalanine, which is affected by a deficiency in the hepatic enzyme phenylalanine hydroxylase. The optimal treatment for PKU disease remains to be determined, necessitating further research. The severity of the disease and the most effective treatment method vary depending on the specific mutation, which necessitates the development of personalized treatment strategies. In this study, we successfully established induced pluripotent stem cell (iPSC) lines from the blood of a PKU patient with the R243Q mutation via Sendai virus-based reprogramming (R243Q-iPSCs). The established R243Q-iPSCs exhibited characteristics of pluripotency, as confirmed through quantitative reverse transcription polymerase chain reaction, western blot, immunocytochemistry, and karyotype analysis. Furthermore, these iPSCs not only successfully differentiated into hepatocytes but also exhibited a complete PKU disease phenotype. These results provide a valuable foundation for PKU disease research, including physiological studies of PKU, gene therapy, drug screening, and the development of platforms for novel cell therapy approaches.

Ischemic stroke is a medical emergency that requires precise diagnosis and prompt treatment. Nonetheless, it is essential to evaluate alternative conditions, such as seizure, peripheral neuropathy and malignancy, with special attention to lymphoma due to its variable clinical manifestations, imaging features, and prognosis. In this report, we present a case of a patient who initially exhibited symptoms and radiological findings considered as lacunar stroke but was ultimately diagnosed with diffuse large B cell lymphoma.

A 5-year-old, 28 kg castrated male Border Collie was referred for surgical intervention following complications from a prior total hip replacement. A physical examination revealed reduced weight-bearing and metallic crepitus on the affected limb. A radiographic assessment confirmed a fractured femoral stem. Extended trochanteric osteotomy (ETO) was performed to extract the well-fixed stem, followed by the removal of the acetabular cup. ETO stabilization was achieved with cerclage wires and a locking plate. Six months postoperatively, the radiographs indicated successful bone healing, and the dog exhibited improved limb function. The ETO technique can provide enhanced surgical access to extract well-fixed implants.

Fatty acids play critical roles in maintaining the cellular functions of T cells and regulating T-cell immunity. This review synthesizes current research on the influence of fatty acids on T-cell subsets, including CD8+ T cells, TH1, TH17, Treg (regulatory T cells), and TFH (T follicular helper) cells. Fatty acids impact T cells by modulating signaling pathways, inducing metabolic changes, altering cellular structures, and regulating gene expression epigenetically. These processes affect T-cell activation, differentiation, and function, with implications for diseases such as autoimmune disease and cancer. Based on these insights, fatty acid pathways can potentially be modulated by novel therapeutics, paving the way for novel treatment approaches for immune-mediated disorders and cancer immunotherapy.
