Biomarker Discovery for Early Detection of Pancreatic Ductal Adenocarcinoma (PDAC) Using Multiplex Proteomics Technology.

Early detection of pancreatic ductal adenocarcinoma (PDAC) can improve survival but is hampered by the absence of early disease symptoms. Imaging remains key for surveillance but is cumbersome and may lack sensitivity to detect small tumors. CA19-9, the only FDA-approved blood biomarker for PDAC, is insufficiently sensitive and specific to be recommended for surveillance.

A Five-Year Retrospective Study on the Clinical Outcomes of Sacral Nerve Stimulation for Neuromodulation of the Lower Urinary Tract in a Tertiary Hospital.

Aim: To assess clinical outcomes in terms of first to second-stage conversion rates, revision rates, and complications for all patients undergoing sacral neuromodulation of the lower urinary tract for the past five years at the Queen Elizabeth Hospital Birmingham.

Method: This is a retrospective observational study. Only patients with the first stage of sacral neuromodulation between January 2017 and January 2023 were included in the study.

Mental health clinical pathways for children and young people with long-term health conditions: A systematic review.

Rationale: Clinical pathways (CPWs) are structured care plans that set out essential steps in the care of patients with a specific clinical problem. Amidst calls for the prioritisation of integrated mental and physical health care for young people, multidisciplinary CPWs have been proposed as a step towards closer integration. There is very limited evidence around CPWs for young people with mental and physical health needs, necessitating a review of the literature.

Practice Trends in Plastic Hand Surgery: An Evaluation of Cases in the TOPS Database.

Background: Previous studies have sought to outline the clinical practice of hand surgeons with plastic surgery training backgrounds. Still, minimal data exist characterizing the scope of hand surgery among plastic surgeons, regardless of the subspecialty fellowship training.

Methods: All hand procedures logged in the Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database from 2002 to 2016 were identified by the Common Procedural Technology (CPT) code and/or "upper extremity" anatomic classification.

Quantum Efficiency Measurement and Modeling of Silicon Sensors Optimized for Soft X-ray Detection.

Hybrid pixel detectors have become indispensable at synchrotron and X-ray free-electron laser facilities thanks to their large dynamic range, high frame rate, low noise, and large area. However, at energies below 3 keV, the detector performance is often limited because of the poor quantum efficiency of the sensor and the difficulty in achieving single-photon resolution due to the low signal-to-noise ratio. In this paper, we address the quantum efficiency of silicon sensors by refining the design of the entrance window, mainly by passivating the silicon surface and optimizing the dopant profile of the n region.

Effect of insulin insufficiency on ultrastructure and function in skeletal muscle.

Background: Decreased insulin availability and high blood glucose levels, the hallmark features of poorly controlled diabetes, drive disease progression and are associated with decreased skeletal muscle mass. We have shown that mice with β-cell dysfunction and normal insulin sensitivity have decreased skeletal muscle mass. This project asks how insulin deficiency impacts on the structure and function of the remaining skeletal muscle in these animals.

Mental health interventions for children and young people with long-term health conditions in Children and Young People's Mental Health Services in England.

Background: Almost a quarter of children and young people (CYP) in England have a long-term health condition (LTC), which increases the risk of developing mental health difficulties. There is a lack of understanding regarding the routine provision and efficacy of mental health interventions for CYP with LTCs within Children and Young People's Mental Health Services (CYPMHS).

Methods: This study analysed national service-reported data in England from two secondary datasets.

Susac syndrome: a case report with initial presentation of incomplete bitemporal hemianopia.

Susac syndrome (SS) is a rare microangiopathy affecting the precapillary arterioles of the brain, inner ear, and retina. We present a novel case of SS, presenting as acute incomplete bitemporal field loss in addition to temporally spaced neurological and vestibulocochlear symptoms. A 39-year-old female was referred to the ophthalmology clinic with acute incomplete bitemporal hemianopia and worsening hemicrania.

Plasma Metanephrines Yield Fewer False-Positive Results Than Urine Metanephrines in Patients With Obstructive Sleep Apnea.

Context: Obstructive sleep apnea (OSA) is associated with increased nocturnal sympathetic activity. In OSA patients, elevations in metanephrines may lead to false-positive tests when evaluating for pheochromocytoma or paraganglioma (PPGL).

Objective: To evaluate whether morning plasma metanephrines would lead to fewer false-positive results than 24-hour urinary metanephrines in OSA patients.

Factors that affect water column hydrocarbon concentrations have minor impacts on microbial responses following simulated diesel fuel spills.

Effects of season and mixing on hydrocarbon concentrations and the microbial community response was explored in a series of mesocosm experiments simulating surface spills of diesel into coastal waters. Mixing of any amount contributed to hydrocarbons entering the water column, but diesel fuel composition had a significant effect on hydrocarbon concentrations. Higher initial concentrations of aromatic hydrocarbons resulted in higher water column concentrations, with minimal differences among seasons due to high variability.

Disulfide re-bridging reagents for single-payload antibody-drug conjugates.

Numerous antibody-drug conjugate (ADC) linker technologies exist for the synthesis of ADCs with drug-to-antibody ratios (DARs) being an even integer (typically 2, 4 or 8). However, ADCs with odd-integer DARs are significantly harder to synthesise. Here, we report the synthesis of ADCs loaded with a single warhead, using TetraDVP linkers which simultaneously re-bridge all four interchain disulfides of an IgG1 antibody.

ApoA-I and Diabetes.

ApoA-I-the main apolipoprotein constituent of the HDL (high-density lipoprotein) fraction of human plasma-is of therapeutic interest because it has several cardioprotective functions. Recent reports have established that apoA-I also has antidiabetic properties. In addition to improving glycemic control by increasing insulin sensitivity, apoA-I improves pancreatic β-cell function by amplifying expression of transcription factors that are essential for β-cell survival and increasing insulin production and secretion in response to a glucose challenge.

Synthesis of sp-rich heterocyclic frameworks by a divergent synthesis strategy.

Fragment-based lead discovery (FBLD) often relies on flat, aromatic compounds which display undesirable physicochemical properties with limited exit vectors for fragment growth. Herein, we report concise synthetic strategies to sp-rich heterocyclic fragments encompassing polar exit vectors poised for fragment-to-lead (F2L) development.

Screening Echocardiography in Adults with Down Syndrome.

Down syndrome is the most common chromosomal disorder in the United States, occurring in about 14.14/10,000 births. It is associated with multiple medical anomalies, including cardiac, gastrointestinal, musculoskeletal, and genitourinary abnormalities, which increases the burden of morbidity for this patient population.

Histone 4 lysine 5/12 acetylation enables developmental plasticity of Pristionchus mouth form.

Development can be altered to match phenotypes with the environment, and the genetic mechanisms that direct such alternative phenotypes are beginning to be elucidated. Yet, the rules that govern environmental sensitivity vs. invariant development, and potential epigenetic memory, remain unknown.

Impact of Impaired Cholesterol Homeostasis on Neutrophils in Atherosclerosis.

Atherosclerosis is complex chronic disease characterized by intimal cholesterol accumulation and vascular inflammation. There is a well-established relationship of hypercholesterolemia and inflammation with atherosclerosis. However, the link between inflammation and cholesterol is not completely understood.

Proton-pump inhibitor use amongst patients with severe hypomagnesemia.

Long-term proton pump inhibitor (PPI) use has been associated with hypomagnesemia. It is unknown how frequently PPI use is implicated in patients with severe hypomagnesemia, and its clinical course or risk factors. All patients with severe hypomagnesemia from 2013 to 2016 in a tertiary center were assessed for likelihood of PPI-related hypomagnesemia using Naranjo algorithm, and we described the clinical course.

Single-Shot ChAd3-MARV Vaccine in Modified Formulation Buffer Shows 100% Protection of NHPs.

Marburg virus (MARV) is a virus of high human consequence with a case fatality rate of 24-88%. The global health and national security risks posed by Marburg virus disease (MVD) underscore the compelling need for a prophylactic vaccine, but no candidate has yet reached regulatory approval. Here, we evaluate a replication-defective chimpanzee adenovirus type 3 (ChAd3)-vectored MARV Angola glycoprotein (GP)-expressing vaccine against lethal MARV challenge in macaques.
