Pharmacokinetics of PP353, a formulation of linezolid for intervertebral disc administration, in patients with chronic low back pain and Modic change Type 1: A first-in-human, Phase 1b, open-label, single-dose study.

Background: Bacterial infection of the intervertebral disc is difficult to treat because the tissue is usually not vascularized and systemic antibiotic therapy may not reach optimal antibacterial exposure. Here we characterize the safety, tolerability, and pharmacokinetics of PP353, a suspension of micronized linezolid, formulated for direct intervertebral disc administration.

Methods: The safety, tolerability, and pharmacokinetics of an intradiscal administration of PP353, was assessed in Part A of a Phase 1b study and consisted of a single injection of study drug (3 mL of PP353 and 150 mg linezolid).

Central Pulse Wave Velocity and Augmentation Index Are Repeatable and Reproducible Measures of Arterial Function.

Background And Aims: Arterial function (specifically arterial stiffness) is an important cardiovascular risk factor. Pulse wave velocity (PWV) and augmentation index (Al ) are established indicators of arterial function. The present study aimed to evaluate the repeatability and reproducibility of PWV and Al in healthy individuals.

National audit of patient reported experience of radical cystectomy for bladder cancer pathways.

Objective: The objective of this study was to measure and describe the national patient experience of radical cystectomy (RC) pathways in the UK using the validated Cystectomy-Pathway Assessment Tool (C-PAT).

Patients And Methods: A cohort of 1081 patients who underwent RC for bladder cancer, between 1 January 2021 and 31 July 2022 at 33 UK cystectomy centres, returned completed C-PAT responses. SPSS was employed for data summary statistics, including median, interquartile range, Mann Whitney U test or Chi-square test with a 95% confidence interval to assess statistical significance between potentially associated variables.

Parameter estimation of a model describing the human fingers.

The goal of this paper is twofold: firstly, to provide a novel mathematical model that describes the kinematic chain of motion of the human fingers based on Lagrangian mechanics with four degrees of freedom and secondly, to estimate the model parameters using data from able-bodied individuals. In the literature there are a variety of mathematical models that have been developed to describe the motion of the human finger. These models offer little to no information on the underlying mechanisms or corresponding equations of motion.

Evaluation of an AI Model to Assess Future Breast Cancer Risk.

Background Accurate breast cancer risk assessment after a negative screening result could enable better strategies for early detection. Purpose To evaluate a deep learning algorithm for risk assessment based on digital mammograms. Materials and Methods A retrospective observational matched case-control study was designed using the OPTIMAM Mammography Image Database from the National Health Service Breast Screening Programme in the United Kingdom from February 2010 to September 2019.

Oncological and functional outcomes of organ-preserving cystectomy versus standard radical cystectomy: A systematic review and meta-analysis.

Introduction: Radical cystectomy (RC) is historically considered the gold standard treatment for muscle invasive and high-risk non-muscle invasive bladder cancer. However, this technique leaves the majority of patients of both sexes with poor sexual and urinary function. Organ-sparing cystectomy (OSC) techniques are emerging as an alternative to the standard procedure to preserve these functions, without compromising the oncological outcomes.

Validity and reliability of short-term heart-rate variability from disposable electrocardiography leads.

Background And Aims: Single-use electrocardiography (ECG) leads have been developed to reduce healthcare-associated infection. This study compared the validity and reliability of short-term heart rate variability (HRV) obtained from single-use disposable ECG leads.

Methods: Thirty healthy subjects (33 ± 10 years; 9 females) underwent 5-min resting HRV assessments using disposable (single use) ECG cable and wire system (Kendall DL™ Cardinal Health) and a standard, reusable ECG leads (CardioExpress, Spacelabs Healthcare).

Long-term functional outcomes following paediatric traumatic elbow dislocation, a clinical retrospective cohort study.

Background: Paediatric traumatic elbow dislocation occurs in 6 per 100,000 children per year and if not treated promptly can result in a poor outcome. Despite this, the long-term clinical and functional outcome of these injuries has not been well described using modern patient-reported outcome tools. The aim of our study was present the outcome of these injuries in the long term.

The Role of Nocturnal Blood Pressure and Sleep Quality in Hypertension Management.

The accurate measurement, prediction and treatment of high blood pressure (BP) are essential to the management of hypertension and the prevention of its associated cardiovascular (CV) risks. However, even if BP is optimally controlled during the day, nocturnal high blood pressure may still increase the risk of CV events. The pattern of circadian rhythm of BP can be evaluated by ambulatory BP monitoring (ABPM).

Non-medical practitioner roles in the UK: who, where, and what factors influence their development?

Background: traditional health workforce roles are changing, with existing roles being extended and advanced, while new roles are being created, often undertaking duties previously completed by doctors, sometimes referred to as non-medical practitioners (NMPs).

Aim: to investigate which NMP roles exist within the UK, mapping distribution, and explore factors influencing their development and recruitment.

Methods: two descriptive, exploratory, online self-completed semi-structured questionnaires were used.

Prolonged treatment with vitamin D in postmenopausal women with primary hyperparathyroidism.

Introduction/background: Vitamin D deficiency further increases circulating parathyroid hormone (PTH) levels in patients with primary hyperparathyroidism (pHPT), with potential detrimental effects on bone mass.

Methods: This was an observational clinical study in consecutive conservatively treated postmenopausal women (n=40) with pHPT and coexistent 25-hydroxyvitamin D deficiency (25OHD ≤50 nmol/l (≤20 ng/ml)). Patients who showed an increase in serum 25OHD above the threshold of vitamin D deficiency (>50 nmol/l; n=28) using treatment with various commonly prescribed vitamin D preparations were, for the purposes of statistical analyses, allocated to the treatment group.

Acute versus gradual correction of idiopathic tibia vara in children: a systematic review.

Background: Idiopathic tibia vara (Blount disease) is an acquired form of tibial deformity found mainly in children who are Afro-Caribbean and obese. It is uncommon. Several methods have been described for the surgical treatment of this condition, which can be categorized as either acute or gradual correction.
