Comparison of cardiac magnetic resonance imaging, functional and haemodynamic variables in pulmonary arterial hypertension: insights from REPAIR.

Background: Measures that can detect large treatment effects are important for monitoring therapeutic effectiveness. The 2022 European Society of Cardiology/European Respiratory Society guidelines highlight the importance of imaging in monitoring disease status and treatment response in pulmonary arterial hypertension (PAH). Are the standardised treatment effect sizes (STES) of cardiac magnetic resonance imaging (cMRI) comparable with functional and haemodynamic variables?

Methods: REPAIR (ClinicalTrials.

Clinical impact of videocapsule endoscopy and device-assisted enteroscopy in non-bleeding small bowel lesions.

Background: Videocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) are part of the diagnostic and therapeutic work-up of indications other than suspected small bowel bleeding (OSBB). The literature is currently lacking studies describing these procedures in this particular setting.

Objectives: We assessed the clinical impact of VCE and DBE in a large monocentric cohort of OSBB patients, as compared to a control group of suspected small bowel bleeding (SSBB) patients who underwent enteroscopy over the same period.

Pulmonary Vascular Research Institute GoDeep: A meta-registry merging deep phenotyping datafrom international PH reference centers.

The Pulmonary Vascular Research Institute GoDeep meta-registry is a collaboration of pulmonary hypertension (PH) reference centers across the globe. Merging worldwide PH data in a central meta-registry to allow advanced analysis of the heterogeneity of PH and its groups/subgroups on a worldwide geographical, ethnical, and etiological landscape (ClinTrial. gov NCT05329714).

Prevalence of acute dizziness and vertigo in cortical stroke.

Background And Purpose: In posterior circulation stroke, vertigo can be a presenting feature. However, whether isolated hemispheric strokes present with vertigo is less clear, despite a few single case reports in the literature. Here, (a) the prevalence of vertigo/dizziness in acute stroke is explored and (b) the cortical distribution of the lesions in relation to both the known vestibular cortex and the evolution of the symptoms, are considered.

Treatment Response of Deferiprone in Infratentorial Superficial Siderosis: a Systematic Review.

Superficial siderosis describes haemosiderin deposition on the surface of the brain. When present on infratentorial structures, it can cause ataxia, sensorineural hearing loss and pyramidal signs. There is no proven treatment and patients experience slow progression of symptoms.

Endoscopic management of enteral tubes in adult patients - Part 1: Definitions and indications. European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

ESGE recommends considering the following indications for enteral tube insertion: (i) clinical conditions that make oral intake impossible (neurological conditions, obstructive causes); (ii) acute and/or chronic diseases that result in a catabolic state where oral intake becomes insufficient; and (iii) chronic small-bowel obstruction requiring a decompression gastrostomy.Strong recommendation, low quality evidence.ESGE recommends the use of temporary feeding tubes placed through a natural orifice (either nostril) in patients expected to require enteral nutrition (EN) for less than 4 weeks.

Diagnosis and Treatment Patterns in Celiac Disease.

Celiac disease (CD) is an immune-mediated gastrointestinal (GI) disorder driven by innate and adaptive immune responses to gluten. Presentation of CD has changed over time, with non-GI symptoms, such as anemia and osteoporosis, presenting more commonly. With improved screening and diagnostic methods, the reported prevalence of CD has increased globally, and there is considerable global variation in diagnostic and treatment practices.

Neurological Manifestations of Neuropathy and Ataxia in Celiac Disease: A Systematic Review.

Celiac disease (CD) is an immune-mediated gastrointestinal disorder driven by innate and adaptive immune responses to gluten. Patients with CD are at an increased risk of several neurological manifestations, frequently peripheral neuropathy and gluten ataxia. A systematic literature review of the most commonly reported neurological manifestations (neuropathy and ataxia) associated with CD was performed.

Systematic Literature Review of the Economic Burden of Celiac Disease.

Background: The prevalence of celiac disease (CD) has rapidly increased over recent decades, but costs related to CD remain poorly quantified.

Objective: This systematic review assessed the economic burden of CD in North America and Europe.

Methods: MEDLINE, EMBASE, EconLit, and the Cochrane Library databases were systematically searched to identify English-language literature from 2007 to 2018 that assessed costs, cost effectiveness, and health resource utilization for CD.

Phenytoin-related ataxia in patients with epilepsy: clinical and radiological characteristics.

Purpose: Phenytoin is an effective anticonvulsant for focal epilepsy. Its use can be associated with long-term adverse effects including cerebellar ataxia. Whilst phenytoin is toxic to Purkinje cells in vitro; the clinical and radiological phenotype and mechanism of cerebellar degeneration in vivo remain unclear.

Predicting Response to Intravesical Bacillus Calmette-Guérin Immunotherapy: Are We There Yet? A Systematic Review.

Context: Bacillus Calmette-Guérin (BCG) is currently the most effective intravesical therapy for nonmuscle invasive bladder cancer, reducing not only recurrence rates but also preventing progression and reducing deaths. However, response rates to BCG vary widely and are dependent on a multitude of factors.

Objective: To review existing data on clinical, pathologic, immune, and molecular markers that allow prediction of BCG response.

The Use of Biomarkers to Manage Men with Metastatic Prostate Cancer: One Day, But Not Yet.

Metastatic castration-resistant prostate cancer has poor survival outcomes. New prognostic gene panels are being used in developing ways to interrogate the likely natural history of an individual's disease. Biomarker innovations to calculate tumour burden also hold promise for the future, but there is still some way to go to validate and stratify their use.

Diagnosis of Non-Celiac Gluten Sensitivity (NCGS): The Salerno Experts' Criteria.

Non-Celiac Gluten Sensitivity (NCGS) is a syndrome characterized by intestinal and extra-intestinal symptoms related to the ingestion of gluten-containing food, in subjects that are not affected by either celiac disease or wheat allergy. Given the lack of a NCGS biomarker, there is the need for standardizing the procedure leading to the diagnosis confirmation. In this paper we report experts' recommendations on how the diagnostic protocol should be performed for the confirmation of NCGS.

Risk of rupture of small anterior communicating artery aneurysms is similar to posterior circulation aneurysms.

Background And Purpose: According to the International Study of Unruptured Intracranial Aneurysms (ISUIA), anterior circulation (AC) aneurysms of <7 mm in diameter have a minimal risk of rupture. It is general experience, however, that anterior communicating artery (AcoA) aneurysms are frequent and mostly rupture at <7 mm. The aim of the study was to assess whether AcoA aneurysms behave differently from other AC aneurysms.

Painful diabetic peripheral neuropathy: consensus recommendations on diagnosis, assessment and management.

Painful diabetic peripheral neuropathy (DPN) is common, is associated with significant reduction in quality of life and poses major treatment challenges to the practising physician. Although poor glucose control and cardiovascular risk factors have been proven to contribute to the aetiology of DPN, risk factors specific for painful DPN remain unknown. A number of instruments have been tested to assess the character, intensity and impact of painful DPN on quality of life, activities of daily living and mood.

Endocrine-mediated mechanisms of fatigue during treatment with interferon-alpha.

Fatigue occurs in more than 70% of patients treated with interferon-alpha (IFN-alpha) and is the most problematic toxicity associated with IFN-based immunotherapy. Abundant evidence suggests that immune-mediated endocrine disease occurs during IFN-alpha therapy, which may contribute to the etiology of fatigue. Autoimmune thyroid disease is a well-recognized consequence of IFN-alpha therapy and may be mediated by the induction of IFN-gamma production by lymphocytes.

An in vitro study of the pharmacological responses of rat middle cerebral artery: effects of overnight storage.

This study was designed to establish the in vitro pharmacological responses of rat middle cerebral arteries (MCA), and also their susceptibility to overnight cold storage at 4 degrees C. MCAs were harvested from rats and pharmacological responses were studied using a Mulvany myograph. Responses to prostaglandin F2 alpha (PGF2 alpha), uridine triphosphate (UTP), noradrenaline (NA) and histamine were determined to investigate receptor-dependent responses, sodium nitroprusside and papaverine to investigate receptor-independent relaxation and L-arginine and N omega-Nitro-L-arginine methyl ester (L-NAME) to examine nitric oxide synthase-dependent responses.
