Regulation of Paneth cell-specific genes in COVID-19 patients and SARS-CoV-2-infected mice by quantification of mRNA from exfoliated cells in stool samples.

The Paneth cell, a secretory cell of the small intestine, expresses numerous host defense proteins, and is hypothesized to play an important role in host defense against infection. However, studying gene expression in this cell requires invasive procedures. To test the hypothesis that we could observe Paneth cell-specific gene regulation from exfoliated cells in infectious conditions, we obtained stool samples from patients with COVID-19 and uninfected controls.

Fixed-dose combination (FDC) therapy offers a promising approach to addressing this challenge by providing a convenient single-tablet solution that enhances the effectiveness of blood pressure control. In our systematic review, we assess the effectiveness of perindopril/amlodipine FDC in managing blood pressure.

Opioid prescribing practices in breast oncologic surgery-A retrospective cohort study.

Background: In breast oncologic surgery, 75% of patients receive a postoperative opioid prescription at discharge, and 10%-20% will develop persistent opioid use. To inform future institutional guidelines, the objective of this study was to determine baseline opioid prescribing patterns in a single high-volume, referral-based breast center. We hypothesized that opioid prescribing practices varied between procedures and operating surgeons.

SABRE hyperpolarization of nicotinamide derivatives and their molecular dynamics properties.

Signal amplification by reversible exchange hyperpolarization explores the chemical structure and kinetic properties of nicotinamide derivatives. -Benzyl nicotinamide and nicotinic acid hydrazide compounds display relatively fast dissociation rates of approximately 7-8 s and long proton relaxation times of 5-20 s, respectively. Consequently, these substrates exhibit remarkable signal enhancements, reaching approximately 175 and 102 fold, respectively, underscoring the efficacy of the hyperpolarization technique in elucidating the behavior of these compounds.

Accurate detection of enzymatic degradation processes of gelatin-alginate microcapsule by H NMR spectroscopy: Probing biodegradation mechanism and kinetics.

With an increase in the severity of environmental pollution caused by microbeads, the development of biodegradable microcapsules that can be applied in diverse fields has attracted significant attention. The degradation processes are directly related to biodegradable microcapsule creation with high stability and persistence. In this study, biodegradable microcapsules are synthesized via a complex coacervation approach using gelatin and alginate as the capsule main wall materials; additionally, enzyme-induced decomposition mechanisms are proposed by observing spectral changes in proton nuclear magnetic resonance (H NMR) analyses.

Association of the magnitude of the difference in blood pressure between office and ambulatory measurements with blood pressure variability in untreated individuals.

Objectives: We evaluated the association between cardiovascular risk factors and the magnitude of the difference in systolic blood pressure (SBP) between office and ambulatory measurements (masked effect) in untreated individuals without apparent hypertension-mediated organ damage (HMOD).

Methods: The inclusion criteria were 1) age ≥ 20 years, 2) blood pressure ≥ 140/90 mmHg at the outpatient clinic, and 3) not receiving antihypertensive medications. The difference between office and ambulatory SBP was calculated by subtracting the ambulatory daytime SBP from the office SBP.

Dynamic Nuclear Polarization of Selectively Si-Enriched Core@shell Silica Nanoparticles.

Si silica nanoparticles (SiO NPs) are promising magnetic resonance imaging (MRI) probes that possess advantageous properties for in vivo applications, including suitable biocompatibility, tailorable properties, and high water dispersibility. Dynamic nuclear polarization (DNP) is used to enhance Si MR signals via enhanced nuclear spin alignment; to date, there has been limited success employing DNP for SiO NPs due to the lack of endogenous electronic defects that are required for the process. To create opportunities for SiO-based Si MRI probes, we synthesized variously featured SiO NPs with selective Si isotope enrichment on homogeneous and core@shell structures (shell thickness: 10 nm, core size: 40 nm), and identified the critical factors for optimal DNP signal enhancement as well as the effective hyperpolarization depth when using an exogenous radical.

Hyperpolarized Si magnetic resonance spectroscopy of selectively radical-embedded silica nanoparticles.

The embedding of radicals at different locations within core@shell silica nanoparticles contributes to enhanced polarization capability and can be self-polarized without adding external radicals. With grafting the radical source homogenously inside of the nanoparticles, a significant Si hyperpolarization signal enhancement of 49.4 was obtained.

Sentinel lymph node biopsy in women over 70: Evaluation of rates of axillary staging and impact on adjuvant therapy in elderly women.

Background: The 2016 Society of Surgical Oncology Choosing Wisely guidelines recommended against routine sentinel lymph node biopsy in women ≥70 years old with favorable, early-stage breast cancer, as sentinel lymph node biopsy does not decrease recurrence or mortality in these patients. This study's objective was to evaluate the use of sentinel lymph node biopsy and its effect on management in elderly patients.

Methods: A retrospective analysis of female patients ≥70 years old with stage I-II, clinically node-negative, hormone-receptor positive, HER2-negative disease undergoing upfront breast cancer surgery between 2017 and 2019.

S110-Opioid-free analgesia after outpatient general surgery: A qualitative study focused on the perspectives of patients and clinicians involved in a pilot trial.

Background: Opioid-free analgesia (OFA) may mitigate opioid-related harms after outpatient general surgery; however, the comparative effectiveness of this approach should be assessed in robust randomized controlled trials (RCTs). Undertaking an RCT on OFA raises important practical concerns, including surgeon and patient hesitation regarding pain management without opioids. We conducted a qualitative study to explore patients' and clinicians' perspectives and experiences with a pilot trial focused on OFA after outpatient general surgery.

Feasibility of Prospectively Comparing Opioid Analgesia With Opioid-Free Analgesia After Outpatient General Surgery: A Pilot Randomized Clinical Trial.

Importance: The overprescription of opioids to surgical patients is recognized as an important factor contributing to the opioid crisis. However, the value of prescribing opioid analgesia (OA) vs opioid-free analgesia (OFA) after postoperative discharge remains uncertain.

Objective: To investigate the feasibility of conducting a full-scale randomized clinical trial (RCT) to assess the comparative effectiveness of OA vs OFA after outpatient general surgery.

Opioid versus opioid-free analgesia after surgical discharge: a systematic review and meta-analysis of randomised trials.

Background: Excessive opioid prescribing after surgery has contributed to the current opioid crisis; however, the value of prescribing opioids at surgical discharge remains uncertain. We aimed to estimate the extent to which opioid prescribing after discharge affects self-reported pain intensity and adverse events in comparison with an opioid-free analgesic regimen.

Methods: In this systematic review and meta-analysis, we searched MEDLINE, Embase, the Cochrane Library, Scopus, AMED, Biosis, and CINAHL from Jan 1, 1990, until July 8, 2021.

Correlation of Chest X-Ray Scores in SARS-CoV-2 Patients With the Clinical Severity Classification and the Quick COVID-19 Severity Index.

Objectives This study aimed to assess the role of chest X-ray (CXR) scoring methods and their correlations with the clinical severity categories and the Quick COVID-19 Severity Index (qCSI). Methods We conducted a retrospective study of 159 COVID-19 patients who were diagnosed and treated at the University Medical Center between July and September 2021. Chest X-ray findings were evaluated, and severity scores were calculated using the modified CXR (mCXR), Radiographic Assessment of Lung Edema (RALE), and Brixia scoring systems.

Algorithm for diagnosing hypertension using out-of-office blood pressure measurements.

The authors developed and validated a diagnostic algorithm using the optimal upper and lower cut-off values of office and home BP at which ambulatory BP measurements need to be applied. Patients presenting with high BP (≥140/90 mm Hg) at the outpatient clinic were referred to measure office, home, and ambulatory BP. Office and home BP were divided into hypertension, intermediate (requiring diagnosis using ambulatory BP), and normotension zones.

Natural Course of New-Onset Postoperative Atrial Fibrillation after Noncardiac Surgery.

Background Postoperative atrial fibrillation (POAF) is common after cardiac surgery, but little is known about its incidence and natural course after noncardiac surgery. We evaluated the natural course and clinical impact of POAF and the long-term impact of anticoagulation therapy in patients without a history of atrial fibrillation (AF) undergoing noncardiac surgery. Methods and Results We retrospectively analyzed the database of Asan Medical Center (Seoul, Korea) to identify patients who developed new-onset POAF after undergoing noncardiac surgery between January 2006 and January 2016.
