Background: The 1.5 mm Baby J hydrophilic narrow J-tipped wire is a development of the standard 0.035" 3-mm J-tipped peripheral guidewire, designed to improve efficiency of transradial coronary procedures by safely navigating small caliber radial arteries to the aorta.

Cardiogenic shock without hypotension in acute severe primary mitral regurgitation: a case report.

A 60-year-old gentleman who presented with features of end-organ hypoperfusion despite initial hypertension was promptly diagnosed with cardiogenic shock following evidence of hyperlactatemia on biochemistry and left ventricular global hypokinesis with severe mitral regurgitation on transthoracic echocardiogram. He responded well to dobutamine and later underwent definitive surgical mitral valve replacement.

Primary neurolymphomatosis diagnosed by spinal nerve root biopsy.

Primary neurolymphomatosis is the direct infiltration of lymphomatous neoplastic cells into nerve roots and/or peripheral nerves. A 67-year-old man had a 24-month history of progressive and severe left lower limb neuropathic pain, ipsilateral ankle dorsiflexion weakness and gait disturbance. Gadolinium-enhanced MRI showed thickening and enhancement of the cauda equina, L5, S1 and S2 nerve roots.

An observational objective job analysis of role related tasks undertaken by Royal Navy sailors.

Background: The current in-service Royal Naval Fitness Test has two elements to test the aerobic endurance and muscular strength of Service Personnel through generic field-based tests and a short job task simulation. However, in 2017 the Royal Navy (RN) identified a requirement to update their in-service fitness test to align with international best practice.

Objective: The purpose of this study was to conduct an Objective Job Task Analysis on critical, physically demanding tasks that could be undertaken by RN sailors during sea deployments.

A preliminary study of the thermal strain experienced by dive support boat personnel.

Anecdotal evidence indicated some British military dive support boat personnel suffer from uncomfortably cold hands and feet, which could impair their performance and be associated with reductions in core body temperature. This study collected preliminary data on thermal stress and cognitive performance of personnel taking part in a cold-weather training exercise. Six men were monitored during four boat transits in a range of climatic conditions (air temperature +1.

Does Collaboration between General Practitioners and Pharmacists Improve Risk Factors for Cardiovascular Disease and Diabetes? A Systematic Review and Meta-Analysis.

Objective: To assess whether inter-professional, bidirectional collaboration between general practitioners (GPs) and pharmacists has an impact on improving cardiovascular risk outcomes among patients in the primary care setting. It also aimed to understand the different types of collaborative care models used.

Study Design: Systematic review and Hartung-Knapp-Sidik-Jonkman random effects meta-analyses of randomised control trials (RCTs) in inter-professional bidirectional collaboration between GP and pharmacists assessing a change of patient cardiovascular risk in the primary care setting.

The associations between women who are immigrants, refugees, or asylum seekers, access to universal healthcare, and the timely uptake of antenatal care: A systematic review.

Background: The World Health Organization (WHO) recommends that antenatal care (ANC) commence before 12 weeks' gestation to reduce the risk of obstetric and perinatal complications. Immigrants, refugees, and asylum seekers are at higher risk for late or non-initiation of ANC, and exclusion from universal healthcare (UHC) may be a contributing factor.

Aims: The aims were to synthesise evidence regarding uptake of ANC and to examine if this is associated with inadequate access to UHC and to evaluate the link between ANC and the risk of pregnancy outcomes in the immigrant, refugee and asylum seeker population.

Do bisphosphonates and RANKL inhibitors alter the progression of coronary artery calcification? A systematic review and meta-analysis protocol.

Introduction: Whether bisphosphonates and RANKL inhibitors play a novel role in delaying cardiovascular calcification is unknown. Their action on regulatory enzymes in the mevalonic acid pathway, which is implicated in both bone and lipid metabolism, may be a novel therapeutic target to manage coronary artery disease (CAD). Such therapies may particularly be relevant in those for whom traditional cardiovascular therapies are no longer sufficient to control disease progression.

In vitro and integrated in vivo strategies to reduce animal use in genotoxicity testing.

Scientific, financial, and ethical drivers have led to unprecedented interest in implementing human-relevant, mechanistic in vitro and in silico testing approaches. Further, as non-animal approaches are being developed and validated, researchers are interested in strategies that can immediately reduce the use of animals in toxicology testing. Here, we aim to outline a testing strategy for assessing genotoxicity beginning with standard in vitro methods, such as the bacterial reverse mutation test and the in vitro micronucleus test, followed by a second tier of in vitro assays including those using advanced 3D tissue models.

Carbon Nanotube Exposure Triggers a Cerebral Peptidomic Response: Barrier Compromise, Neuroinflammation, and a Hyperexcited State.

The unique physicochemical properties of carbon nanomaterials and their ever-growing utilization generate a serious concern for occupational risk. Pulmonary exposure to these nanoparticles induces local and systemic inflammation, cardiovascular dysfunction, and even cognitive deficits. Although multiple routes of extrapulmonary toxicity have been proposed, the mechanism for and manner of neurologic effects remain minimally understood.

The incidence of breast health issues and the efficacy of a sports bra fit and issue service in British Army recruits.

Increasing retention of female recruits throughout Basic Training (BT) is a key priority for the British Army. The aims of this study were two-fold; (i) quantify breast health issues and sports bra usage within female British Army recruits, and (ii) assess the influence of professionally fitted sports bras on breast health and bra fit issues across 13 weeks of BT. A survey was completed by 246 female recruits that identified the incidence of breast health issues during BT.

Effect of β /β -adrenoceptor blockade on β -adrenoceptor activity in the rat cremaster muscle artery.

Background And Purpose: The physiological role of vascular β -adrenoceptors is not fully understood. Recent evidence suggests cardiac β -adrenoceptors are functionally effective after down-regulation of β /β -adrenoceptors. The functional interaction between the β -adrenoceptor and other β-adrenoceptor subtypes in rat striated muscle arteries was investigated.

No Differences Between Beetroot Juice and Placebo on Competitive 5-km Running Performance: A Double-Blind, Placebo-Controlled Trial.

The authors examine the effect of an acute dose of beetroot juice on endurance running performance in "real-world" competitive settings. In total, 70 recreational runners (mean ± SD: age = 33.3 ± 12.

Estimates of Tibial Shock Magnitude in Men and Women at the Start and End of a Military Drill Training Program.

Introduction: Foot drill is a key component of military training and is characterized by frequent heel stamping, likely resulting in high tibial shock magnitudes. Higher tibial shock during running has previously been associated with risk of lower limb stress fractures, which are prevalent among military populations. Quantification of tibial shock during drill training is, therefore, warranted.

Sex differences in neuromuscular fatigability in response to load carriage in the field in British Army recruits.

Objectives: Women are resistant to neuromuscular fatigue compared to men in response to a range of exercise tasks. The sex differences in the neuromuscular responses to load carriage have yet to be investigated.

Design: Prospective cohort study.

Effects of prefrontal cortex damage on emotion understanding: EEG and behavioural evidence.

Humans are highly social beings that interact with each other on a daily basis. In these complex interactions, we get along by being able to identify others' actions and infer their intentions, thoughts and feelings. One of the major theories accounting for this critical ability assumes that the understanding of social signals is based on a primordial tendency to simulate observed actions by activating a mirror neuron system.

Serum-borne bioactivity caused by pulmonary multiwalled carbon nanotubes induces neuroinflammation via blood-brain barrier impairment.

Pulmonary exposure to multiwalled carbon nanotubes (MWCNTs) causes indirect systemic inflammation through unknown pathways. MWCNTs translocate only minimally from the lungs into the systemic circulation, suggesting that extrapulmonary toxicity may be caused indirectly by lung-derived factors entering the circulation. To assess a role for MWCNT-induced circulating factors in driving neuroinflammatory outcomes, mice were acutely exposed to MWCNTs (10 or 40 µg/mouse) via oropharyngeal aspiration.

dFatp regulates nutrient distribution and long-term physiology in Drosophila.

Nutrient allocation and usage plays an important part in regulating the onset and progression of age-related functional declines. Here, we describe a heterozygous mutation in Drosophila (dFatp) that alters nutrient distribution and multiple aspects of physiology. dFatp mutants have increased lifespan and stress resistance, altered feeding behavior and fat storage, and increased mobility.

Olfactory outcomes after endoscopic transsphenoidal pituitary surgery.

Background: Olfaction has been demonstrated to have a great impact on patients' lives. Transsphenoidal endoscopic pituitary surgery is associated with potentially significant damage to olfactory tissues, but to date this issue has been only poorly documented in the literature.

Study Design: Prospective cohort study comparing olfactory outcomes pre- and postpituitary surgery.
