72%), and the right ventricle (16.12%). Single venous access was used in 67.07% of the patients. Femoral access, which was the most commonly used approach, was used in 85.71% of the patients. The loop was used in 64.70% of the patients. A fractured catheter was the main IFB in 60.76% of the cases (31 patients). Only one complication related to the extraction of an IFB was noted in a single patient who suffered from atrial fibrillation (1.96%). The 30 day mortality rate was zero.

Percutaneous IFB removal should be considered as an alternative for the treatment and retrieval of IFBs because it is a minimally invasive procedure that is relatively simple, safe, and has low complication rates.

Intracavitary electrocardiography (IC-ECG) has been extensively used for locating the catheter tip of the central venous access devices (CVADs) with favorable safety and accuracy. We aimed to evaluate the efficacy, safety, and cost-effectiveness of IC-ECG-guided catheter tip placement for totally implantable venous access port (TIVAP) by comparing with the standard fluoroscopy method.

A total of 231 patients who underwent TIVAP implantation from September 2019 to April 2021 were enrolled in the retrospective study. Fluoroscopy and IC-ECG were conducted intraoperatively to confirm the position of catheter tips. Demographic characteristics, surgical data, the catheter tip position, complication rate, and incidence, cost of procedures, and indwelling time were compared between the two groups. Univariate and multivariate analyses were used to identify the risk factors of TIVAP-related complications.

There was no significance between the fluoroscopy group and the IC-ECG group in terms of the rate of ideal poracy, low risk of complications, and lower cost. It may be considered as an alternative to the standard fluoroscopy method for catheter tip placement of TIVAP.

Despite the better operative results of autogenous brachiocephalic arteriovenous fistula (BC-AVF), it is considered secondary to autogenous radiocephalic AVF (RC-AVF) failure. Here we compared the results of our multidisciplinary management protocol of BC-AVF versus RC-AVF.

A total of 194 matched patients who requested autogenous BC-AVF or RC-AVF surgery between 2017 and 2019 were included in this retrospective study. All patients strictly adhered to our departmental perioperative management protocol for AVF surgery, including vessel status monitoring, exercise with or without a tourniquet, intraoperative flow assessment, and antiplatelet and anticoagulant medications. AVF function and patient status data were acquired from the electronic medical records, and the final evaluation was made via outpatient department visit or phone call in October 2020.

Patients who underwent elective BC-AVF or RC-AVF (n=97 each) were included. The patient groups had similar preoperative clinical characteristics. Artery anortality, the estimated hazard ratio of RC-AVF over BC-AVF was 0.47 (95% CI, 0.19‒1.17, P=0.106) during the observation period.

BC-AVF had good characteristics for hemodialysis without an increased risk of AVF related complications during a median 19-month observation period. BC-AVF did not feature high flow-related complications with the multimodal approach, including preoperative exercise, intraoperative flow assessment to guarantee an adequate flow rate, postoperative exercise, and medications.

In 2014, in addition to male smokers aged 65-75 years, the U.S. Preventive Services Task Force (USPSTF) recommended abdominal aortic aneurysm (AAA) screening for male never-smokers aged 65-75 years with cardiovascular risk factors (Grade C). The USPSTF evolved from a negative to neutral position on screening for female smokers aged 65-75 years (Grade I). We sought to determine whether 2014 guidelines resulted in more AAA repairs in these populations.

We queried the Vascular Quality Initiative national database (2013-2018) for elective endovascular aortic repairs and open aortic repairs. We implemented difference-in-differences (DID) analysis, a causal inference technique that adjusts for secular time trends, to isolate changes in repair numbers due to the 2014 USPSTF guidelines. Our DID models compared changes in repair numbers in patient groups targeted by the USPSTF updates (intervention group) to those in unaffected, older patient groups (control), before and after 2014. The first model compared changessociated with modestly increased repairs in male never-smokers aged 65-75 years only on Medicare. There was no impact among female smokers. Higher-grade recommendations and improved guideline adherence may be requisites for change.

To investigate whether initial emergency department physiological measures and metrics of trauma severity predict functional outcomes and neurologic recovery in traumatic spinal cord injury.

Retrospective analysis of a clinical database.

Merged multicenter data from the Spinal Cord Injury Model Systems (SCIMS) database and National Trauma Data Bank from 6 academic medical centers across the United States.

Patients (N=319) admitted to SCIMS rehabilitation centers within 1 year of injury. The majority of patients were men (76.2%), with a mean age of 44 years (SD, 19y). At rehabilitation admission, the most common neurologic level of injury was low cervical (C5-C8, 39.5%) and ASIA impairment scale (AIS) was A (34.4%).

Primary outcomes were FIM motor score at discharge from inpatient rehabilitation and change in FIM motor score between inpatient rehabilitation admission and discharge. We hypothesized that derangements in emergency department physiological measures, such as decreased blood pressure and oxygen saturation, as well as increased severity of trauma burden, would predict poorer functional outcomes.

Linear regression analysis showed that neurologic level of injury and AIS predicted discharge FIM motor score. Systolic blood pressure, heart rate, oxygen saturation, need for assisted respiration, and presence of penetrating injury did not predict discharge motor FIM or FIM motor score improvement.

Initial emergency department physiological parameters did not prognosticate functional outcomes in this cohort.

To address this, we profiled gene expression at depth in human metaphase II oocytes and bipronuclear (2PN) one-cell embryos. High-resolution single-cell RNA sequencing revealed previously inaccessible oocyte-to-embryo gene expression changes. This confirmed transcript depletion following fertilization (maternal RNA degradation) but also uncovered low-magnitude upregulation of hundreds of spliced transcripts. Gene expression analysis predicted embryonic processes including cell-cycle progression and chromosome maintenance as well as transcriptional activators that included cancer-associated gene regulators. Transcription was disrupted in abnormal monopronuclear (1PN) and tripronuclear (3PN) one-cell embryos. These findings indicate that human embryonic transcription initiates at the one-cell stage, sooner than previously thought. The pattern of gene upregulation promises to illuminate processes involved at the onset of human development, with implications for epigenetic inheritance, stem-cell-derived embryos, and cancer.

Previous research on rates of spinal detection showed a low frequency of patients (5%) experienced delays and additional screening going through airport security. With continuous technology advances in screenings and the rise in cobalt chrome implantation, updated data on patient experiences was needed.

1) Assess the rates of detection and additional screening by traditional metal detectors and full body scanners in patients with metal spinal implants, 2) Compare the rates of detection of various metal types (Titanium and cobalt-chrome, titanium only, and stainless steel) STUDY DESIGN Retrospective PATIENT SAMPLE All spine surgical follow-ups over survey period.

Self-reported open questionnaire; frequency of airport screening, patients' feelings and attitudes towards screening.

Patients were surveyed in the outpatient setting on exposure to metal detectors (Traditional and full-body scanners) after spinal surgery with metallic implants at a single institution. A total of 182 patients were identified af patients had their spinal implants detected at airports and 20% reported detections at other non-airport locations. Full body scanners detect spinal implants more frequently compared to traditional metal detectors (86% vs. 54% of detections, respectively). There was no difference in rate of airport and non-airport detection in patients with cobalt chrome implants compared to other materials.

This leaves open the possibility that ACC represents associative pairing of events, independent of their overt biological significance. Sensory preconditioning13 provides an opportunity to test this. In the first phase, preconditioning, value-neutral sensory stimuli are paired (A→B). To test whether this was learned, subjects are given standard conditioning during which one of the previously neutral sensory cues is paired with a biologically meaningful outcome (B→outcome). During the final probe test, the neutral cue which was never paired with a biologically meaningful outcome is presented alone (A→) and will elicit a conditional response, suggesting that subjects had learned the associative structure during preconditioning and use that knowledge to infer presentation of the biologically relevant outcome (A→B→outcome).
