Risk Factors for Internal Jugular Vein Thrombosis 1 Month After Non-Cuffed Hemodialysis Catheter Removal.

: Complications, namely, catheter-related thrombosis (CRT) and venous stenosis, are associated with non-cuffed hemodialysis catheters used for emergency vascular access. However, only a few reports have demonstrated changes in the venous lumen and intravenous thrombosis after catheter removal. In this study, we comprehensively investigated the risk factors for residual thrombus 1 month after hemodialysis catheter removal.

Impact of the severe acute respiratory syndrome coronavirus 2 pandemic on the incidence of type 1 diabetes mellitus in children in Yamanashi, Japan.

It has been hypothesized that the biopsychosocial stress associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, in combination with the immunological effects of SARS-CoV-2 and pancreatic β-cell dysfunction, may contribute to the onset of type 1 diabetes (T1D) in children. In this study, we documented the incidences of T1D in Yamanashi Prefecture, Japan, from 1986 to 2018, and expanded the analysis to include cases from 2019 to 2022 to evaluate the potential influence of coronavirus disease 2019 (COVID-19) on T1D incidence. The COVID-19 pandemic period was defined as 2020 to 2022.

Treatment success prediction in patients with methicillin-resistant coagulase-negative staphylococci infections, using vancomycin AUC24/MIC ratio: a multicentre retrospective cohort study.

Background: Although vancomycin is commonly used to treat methicillin-resistant coagulase-negative staphylococci (MRCoNS) infections, there are no clear guidelines for the optimal 24 h AUC24/MIC ratio. This study aimed to determine the target AUC24/MIC ratio associated with vancomycin-treated MRCoNS infection outcomes.

Methods: This multicentre retrospective cohort study included adult patients who received vancomycin for ≥5 days for bloodstream infections caused by MRCoNS between January 2018 and December 2023.

Noncanonical TCA cycle fosters canonical TCA cycle and mitochondrial integrity in acute myeloid leukemia.

Cancer cells rely on mitochondrial oxidative phosphorylation (OXPHOS) and the noncanonical tricarboxylic acid (TCA) cycle. In this paper, we shed light on the vital role played by the noncanonical TCA cycle in a host-side concession to mitochondria, especially in highly energy-demanding malignant tumor cells. Inhibition of ATP-citrate lyase (ACLY), a key enzyme in the noncanonical TCA cycle, induced apoptosis by increasing reactive oxygen species levels and DNA damage while reducing mitochondrial membrane potential.

Comprehensive study on central precocious puberty: molecular and clinical analyses in 90 patients.

Context: Defects in MKRN3, DLK1, KISS1, and KISS1R and some disorders, such as Temple syndrome (TS14), cause central precocious puberty (CPP). Recently, pathogenic variants (PVs) in MECP2 have been reported to be associated with CPP.

Objective: We aimed to clarify the contribution of (epi)genetic abnormalities to CPP and clinical and hormonal features in each etiology.

sFlt-1/PlGF ratio predicts serious outcomes in confirmed early-onset preeclampsia.

Objectives: We aimed to determine whether a high ratio of soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) would be associated with serious negative consequences and shorter pregnancy duration in cases of early-onset preeclampsia (PE).

Study Design: This retrospective cohort study included women (n = 65) diagnosed with PE at <34.0 weeks of gestation and recruited from a single primary and tertiary medical centre in Japan.

Dynamic change of cancer genome profiling in metachronous bilateral breast cancer with pathogenic variant.

A 61-year-old woman with pathogenic variant had been treated for 20 years and showed dynamic changes in the genomic profile of her metachronous bilateral breast cancer and metastases. She underwent right breast conservation surgery at age 42-Genome 1, lung metastasis and left axillary lymph node metastasis at age 51, partial excision under local anesthesia for left breast cancer at age 53-Genome 2, left axillary lymph node dissection was added 6 month later-Genome 3. Then, olaparib was administered, and subsequently, left mastectomy was performed for the recurrence of left breast cancer at age 59-Genome 4.

Acquired copy number amplification at the MYC enhancer in human B-precursor acute lymphoblastic leukemia cell lines.

Our study highlights the discovery of recurrent copy number alterations in noncoding regions, specifically blood enhancer cluster (BENC-CNA), in B-precursor acute lymphoblastic leukemia (BCP-ALL) cell lines. We demonstrate that BENC-CNA acts as a super-enhancer, driving MYC expression and possibly contributing to the immortalization and proliferative advantage of BCP-ALL cells in vitro.

Predictive Value of Vancomycin AUC/MIC Ratio for 30-day Mortality in Patients with Severe or Complicated Methicillin-Resistant Staphylococcus aureus Infections: A Multicenter Retrospective Study.
