Lipid Deposition in Skeletal Muscle Tissues and Its Correlation with Intra-Abdominal Fat: A Pilot Investigation in Type 2 Diabetes Mellitus.

This study evaluated metabolites and lipid composition in the calf muscles of Type 2 diabetes mellitus (T2DM) patients and age-matched healthy controls using multi-dimensional MR spectroscopic imaging. We also explored the association between muscle metabolites, lipids, and intra-abdominal fat in T2DM. Participants included 12 T2DM patients (60.

Impact of Inpatient Patient-Provider Language Concordance on Exclusive Breastfeeding Rates Postpartum.

Objective:  Studies outside of obstetrics suggest that patient-provider language concordance may impact the efficacy of educational interventions and overall patient satisfaction. Many pregnant patients who present to the hospital for delivery with initial plans to exclusively breastfeed ultimately leave the hospital supplementing with formula. We aim to examine the impact of language concordance between patients and their primary bedside nurse during the delivery hospitalization period on the relationship between intended and actual feeding practices for term newborns of primiparous patients at a single institution.

Flow and On-Water Synthesis and Cancer Cell Cytotoxicity of Caffeic Acid Phenethyl Amide (CAPA) Derivatives.

Caffeic acid phenethyl ester (CAPE) is a phenolic natural product with a wide range of biological activities, including anticancer activity; however, the ester group of CAPE is metabolically labile. The corresponding amide, CAPA, has improved metabolic stability but limited anticancer activity relative to CAPE. We report the synthesis using flow and on-water Wittig reaction approaches of five previously reported and five novel CAPA analogues.

Unfolding coil localized errors from an imperfect slice profile using a structured autocalibration matrix: An application to reduce outflow effects in cine bSSFP imaging.

Purpose: Balanced steady-state free precession (bSSFP) imaging is susceptible to outflow effects where excited spins leaving the slice as part of the blood stream are misprojected back onto the imaging plane. Previous work proposed using slice-encoding steps to localize these outflow effects from corrupting the target slice, at the expense of prolonged scan time. This present study extends this idea by proposing a means of significantly reducing most of the outflowing signal from the imaged slice using a coil localization method that acquires a slice-encoded calibration scan in addition to the 2D data, without being nearly as time-demanding as our previous method.

Targeted and untargeted serum NMR metabolomics to reveal initial kidney disease in diabetes mellitus.

Serum H NMR metabolomics has been used as a diagnostic tool for screening type 2 diabetes (T2D) with chronic kidney disease (CKD) as comorbidity. This work aimed to evaluate H NMR data to detect the initial kidney damage and CKD in T2D subjects, through multivariate statistical analysis. Clinical data and biochemical parameters were obtained for classifying five experimental groups using KDIGO guidelines: Control (healthy subjects), T2D, T2D-CKD-mild, T2D-CKD-moderate, and T2D-CKD-severe.

Hemoglobin Electrophoresis versus Kleihauer-Betke to Determine Bone Marrow Suppression in Fetuses Undergoing Intrauterine Transfusion.

Objective:  Mainstay therapy for fetuses affected by maternal red cell alloimmunization is serial intrauterine transfusion (IUT). Testing to determine when fetal red cells have been replaced with donor cells historically involves the use of the Kleihauer-Betke (KB) test. Hemoglobin (Hgb) electrophoresis testing may be more rapid with a reduced cost of analysis.

The Impact of Telehealth on Obstetrical Outcomes during the COVID-19 Pandemic.

Objective:  Nationwide, obstetric clinics modified prenatal care to include telehealth visits in response to the coronavirus disease 2019 (COVID-19) pandemic, enabling the opportunity to investigate its impact on patient outcomes. We hypothesized that use of prenatal telehealth visits would increase the number of prenatal visits, decrease the frequency of urgent triage/emergency department (ED) visits, and improve perinatal outcomes. This study aimed to determine the impact of telehealth on number of obstetric prenatal visits and urgent triage/ED visits amidst the COVID-19 pandemic.

Single-shot diffusion trace spectroscopic imaging using radial echo planar trajectories.

Purpose: Demonstrate the feasibility and evaluate the performance of single-shot diffusion trace-weighted radial echo planar spectroscopic imaging (Trace DW-REPSI) for quantifying the trace ADC in phantom and in vivo using a 3T clinical scanner.

Theory And Methods: Trace DW-REPSI datasets were acquired in 10 phantom and 10 healthy volunteers, with a maximum b-value of 1601 s/mm and diffusion time of 10.75 ms.

Elective Induction of Labor following Prior Cesarean Delivery.

Objective:  Following the release of A Randomized Trial of Induction versus Expectant Management (ARRIVE) trial, the induction of labor at 39 weeks has increased in the United States. The risk of uterine rupture and optimal timing of elective induction in those patients with a prior cesarean delivery is not well-described, and they were not included in the original trial. We aimed to determine the risk of uterine rupture in those patients undergoing elective induction of labor with prior cesarean delivery.

Periviable Premature Rupture of Membranes-Maternal and Neonatal Risks: A Systematic Review and Meta-analysis.

Objective:  Periviable premature rupture of membranes (PROM) counseling should describe maternal and neonatal outcomes associated with both immediate delivery and expectant management. Unfortunately, most published data focuses on neonatal outcomes and maternal risk estimates vary widely. We performed a meta-analysis to describe outcomes associated with expectant management compared with immediate delivery of periviable PROM.

First and Second Stage Risk Factors Associated with Perineal Lacerations.

Objective: To determine intrapartum factors associated with perineal laceration at delivery.

Methods: This was a planned secondary analysis of a multicenter randomized clinical trial of delayed versus immediate pushing among term nulliparous women in labor with neuraxial analgesia conducted in the United States. Intrapartum characteristics were extracted from the medical charts.

Optimal misoprostol dosing among patients with a body mass index greater than 30: a randomized controlled trial.

Background: Patients with obesity experience an increased duration of labor with an increased risk for perinatal morbidity. When compared with parturients without obesity, they also experience fewer uterine contractions after administration of misoprostol. It is unclear if the same dose of misoprostol should be used for induction of labor in patients with obesity compared to non-obese patients.

Optimizing Management of the Second Stage of Labor: A Multicenter Randomized Controlled Trial.

To review the findings of the Optimizing Management of the Second Stage of Labor randomized controlled trial in the context of prior and subsequent obstetric literature. A multi-database search was performed in addition to a review of the parent trial and secondary studies. Nulliparous patients with neuraxial anesthesia randomized to either immediate or delayed pushing showed no difference in vaginal delivery rates.

Single-shot diffusion trace-weighted MR spectroscopy: Comparison with unipolar and bipolar diffusion-weighted point-resolved spectroscopy.

This study demonstrates the feasibility and performance of the point-resolved spectroscopy (PRESS)-based, single-shot diffusion trace-weighted sequence in quantifying the trace apparent diffusion coefficient (ADC) in phantom and in vivo using a 3-T MRI/MRS scanner. The single-shot diffusion trace-weighted PRESS sequence was implemented and compared with conventional diffusion-weighted (DW)-PRESS variants using bipolar and unipolar diffusion-sensitizing gradients. Nine phantom datasets were acquired using each sequence, and seven volunteers were scanned in three different brain regions to determine the range and variability of trace ADC values, and to allow a comparison of trace ADCs among the sequences.

What makes a multidisciplinary medication review and deprescribing intervention for older people work well in primary care? A realist review and synthesis.

Background: A third of older people take five or more regular medications (polypharmacy). Conducting medication reviews in primary care is key to identify and reduce/ stop inappropriate medications (deprescribing). Recent recommendations for effective deprescribing include shared-decision making and a multidisciplinary approach.

Enabling Broader Adoption of Biocatalysis in Organic Chemistry.

Biocatalysis is becoming an increasingly impactful method in contemporary synthetic chemistry for target molecule synthesis. The selectivity imparted by enzymes has been leveraged to complete previously intractable chemical transformations and improve synthetic routes toward complex molecules. However, the implementation of biocatalysis in mainstream organic chemistry has been gradual to this point.

The main objective of this work was to evaluate the application of individual and ensemble machine learning models to classify malignant and benign breast masses using features from two-dimensional (2D) correlated spectroscopy spectra extracted from five-dimensional echo-planar correlated spectroscopic imaging (5D EP-COSI) and diffusion-weighted imaging (DWI). Twenty-four different metabolite and lipid ratios with respect to diagonal fat peaks (1.4 ppm, 5.

Impact of household income and Special Supplemental Nutritional Program for Women, Infants, and Children on feeding decisions for infants in the United States.

Background: Despite the known benefits of breastfeeding to infants and mothers, previous studies have demonstrated that underserved women are less likely to exclusively breastfeed. Existing studies on the impact of Special Supplemental Nutritional Program for Women, Infants, and Children enrollment on feeding decisions for infants have conflicting results with low-quality data and metrics.

Objective: This study aimed to examine infant feeding trends nationally in the first week postpartum over a 10-year period, comparing breastfeeding rates for primiparous women with low income who used Special Supplemental Nutritional Program for Women, Infants, and Children resources with those women who did not enroll.

A comparison of criteria for defining metabolic acidemia in live-born neonates and its effect on predicting serious adverse neonatal outcomes.

Background: Metabolic acidemia is a known risk factor for serious adverse neonatal outcomes in both preterm and term infants.

Objective: This study aimed to evaluate the clinical significance of delivery umbilical cord gas measurements with regard to serious adverse neonatal outcomes, and to determine if distinct thresholds for defining metabolic acidemia differ in their ability to predict such adverse neonatal complications.

Study Design: This is a retrospective cohort study of singleton live-born deliveries between January 2011 and December 2019.

Evidence-Based Approaches to Labor Induction.

Importance: The induction rate continues to increase in the United States placing pressure on the health care system with increasing cost and time spent on labor and delivery. Most labor induction regimens have evaluated uncomplicated singleton-term gestations. Unfortunately, the optimal labor regimens of medically complicated pregnancies have not been well described.

Correlated MR spectroscopic imaging of breast cancer to investigate metabolites and lipids: acceleration and compressed sensing reconstruction.

Objectives: The main objective of this work was to detect novel biomarkers in breast cancer by spreading the MR spectra over two dimensions in multiple spatial locations using an accelerated 5D EP-COSI technology.

Methods: The 5D EP-COSI data were non-uniformly undersampled with an acceleration factor of 8 and reconstructed using group sparsity-based compressed sensing reconstruction. Different metabolite and lipid ratios were then quantified and statistically analyzed for significance.

MSW Students' Perspectives on Learning and Delivering a Protocolized, Low-Intensity Transdiagnostic Psychological Intervention: Implications for Experiential Learning.
