Harnessing deep learning to detect bronchiolitis obliterans syndrome from chest CT.

Background: Bronchiolitis Obliterans Syndrome (BOS), a fibrotic airway disease that may develop after lung transplantation, conventionally relies on pulmonary function tests (PFTs) for diagnosis due to limitations of CT imaging. Deep neural networks (DNNs) have not previously been used for BOS detection. This study aims to train a DNN to detect BOS in CT scans using an approach tailored for low-data scenarios.

Interventions implemented through sporting organisations for promoting healthy behaviour or improving health outcomes.

Background: Chronic diseases are the leading cause of mortality and morbidity worldwide. Much of this burden can be prevented by adopting healthy behaviours and reducing chronic disease risk factors. Settings-based approaches to address chronic disease risk factors are recommended globally.

Alternative Deep Brain Stimulation Targets in the Treatment of Isolated Dystonic Syndromes: A Multicenter Experience-Based Survey.

Background: The globus pallidus internus (GPi) is the traditional evidence-based deep brain stimulation (DBS) target for treating dystonia. Although patients with isolated "primary" dystonia respond best to GPi-DBS, some are primary or secondary nonresponders (improvement <25%), showing variability in clinical response.

Objective: The aim was to survey current practices regarding alternative DBS targets for isolated dystonia patients with focus on nonresponders to GPi-DBS.

The Effects of Systemic Tranexamic Acid Administration on Drainage Volume, Length of Hospital Stay, and Postoperative Complications in Reduction Mammaplasty.

Reduction mammaplasty is a common, elective, and safe operation, usually executed in healthy patients. Nonetheless, postoperative complications like bleeding and seroma formation can occur and significantly complicate the postoperative course. Tranexamic acid (TXA), a commonly used antifibrinolytic drug, offers a novel approach to reduce these complications.

Cyberknife radio-neurosurgery for secreting pituitary adenomas treated with single fraction radio-neurosurgery: A systematic review and meta-analysis.

Introduction: Stereotactic radiosurgery (SRS) is one of the treatment options for the management of residual or recurrent secreting pituitary adenomas (PA). While the role of radiosurgery (RS) by Gamma Knife (GK) has been clearly established, Cyberknife (CK) RS has been evaluated in fewer series.

Material And Methods: To perform a systematic review of the literature and meta-analysis, with the aim of focusing on the effect of CK RS on secreting PA.

Dietary or pharmacological inhibition of insulin-like growth factor-1 protects from renal ischemia-reperfusion injury in mice.

One-week protein restriction (PR) limits ischemia-reperfusion (IR) damages and improves metabolic fitness. Similarly, longer-term calory restriction results in increased lifespan, partly via reduced insulin-like growth factor (IGF)-1. However, the influence of short-term PR on IGF-1 and its impact on IR are unknown.

Systolic Blood Pressure and Pulse Pressure in Heart Failure: Pooled Participant-Level Analysis of 4 Trials.

Background: Hypertension is common in patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), and current guidelines recommend treating systolic blood pressure (SBP) to a target <130 mm Hg. However, data supporting treatment to this target are limited. Additionally, pulse pressure (PP), a marker of aortic stiffness, has been associated with increased risk of cardiovascular events, but its prognostic impact in HFpEF has not been extensively studied.

EAES rapid guideline: surgical management of complicated diverticulitis - with ESCP participation.

Background: The surgical management of complicated diverticulitis varies across Europe. EAES members prioritized this topic to be addressed by a clinical practice guideline through an online questionnaire.

Objective: To develop evidence-informed clinical practice recommendations for key stakeholders involved in the treatment of complicated diverticulitis; to improve operative and perioperative outcomes, patient experience and quality of life through a systematic evidence-to-decision approach by a diverse, multidisciplinary panel.

Surgical management of complicated diverticulitis: systematic review and individual patient data network meta-analysis : An EAES/ESCP collaborative project.

Background: We performed a systematic review and network meta-analysis (NMA) of individualized patient data (IPD) to inform the development of evidence-informed clinical practice recommendations.

Methods: We searched MEDLINE, Embase, and Cochrane Central in October 2023 to identify RCTs comparing Hartmann's resection (HR), primary resection and anastomosis (PRA), or laparoscopic peritoneal lavage (LPL) among patients with class Ib-IV Hinchey diverticulitis. Outcomes of interest were prioritized by an international, multidisciplinary panel including two patient partners.

Multiparametric Assessment of Right Ventricular Dysfunction in Heart Failure: An Analysis From PARAGON-HF.

Background: This study aims to characterize right ventricular dysfunction (RVD) in heart failure (HF) with preserved ejection fraction and understand the cumulative prognostic value of abnormal RV echocardiographic parameters in HF with preserved ejection fraction.

Methods And Results: Data from 809 patients in the PARAGON-HF (Prospective Comparison of Angiotensin Receptor-Neprilysin Inhibitor With Angiotensin-Receptor Blocker Global Outcomes in HF With Preserved Ejection Fraction) echocardiographic substudy (55% women, mean age 74±8 years) were analyzed. Correlates of RVD (defined as tricuspid annular plane systolic excursion <1.

Fast High-Resolution Metabolite Mapping in the rat Brain Using H-FID-MRSI at 14.1 T.

Magnetic resonance spectroscopic imaging (MRSI) enables the simultaneous noninvasive acquisition of MR spectra from multiple spatial locations inside the brain. Although H-MRSI is increasingly used in the human brain, it is not yet widely applied in the preclinical setting, mostly because of difficulties specifically related to very small nominal voxel size in the rat brain and low concentration of brain metabolites, resulting in low signal-to-noise ratio (SNR). In this context, we implemented a free induction decay H-MRSI sequence (H-FID-MRSI) in the rat brain at 14.

Phase I clinical trial testing the dose escalation and expansion of Pressurized IntraThoracic Hyperthermic Aerosol Cisplatin administration (PITHAC) for the management of pleural carcinosis.

Background: Pleural carcinosis originates from various cancers. Its management consists in systemic therapies combined to dyspnea relief procedures. Prior studies have tested hyperthermic intrathoracic chemotherapy to treat pleural carcinosis with interesting patient survival results.

Sleep Apnea Events Recognition Based on Polysomnographic Recordings: A Large-Scale Multi-Channel Machine Learning approach.

The gold standard for detecting the presence of apneic events is a time and effort-consuming manual evaluation of type I polysomnographic recordings by experts, often not error-free. Such acquisition protocol requires dedicated facilities resulting in high costs and long waiting lists. The usage of artificial intelligence models assists the clinician's evaluation overcoming the aforementioned limitations and increasing healthcare quality.

Immune modules to guide diagnosis and personalized treatment of inflammatory skin diseases.

Previous advances have identified immune pathways associated with inflammatory skin diseases, leading to the development of targeted therapies. However, there is a lack of molecular approaches that delineate these pathways at the individual patient level for personalized diagnostic and therapeutic guidance. Here, we conduct a cross-comparison of expression profiles from multiple inflammatory skin diseases to identify gene modules defining relevant immune pathways.

Searching national DNA databases with complex DNA profiles: An empirical study using probabilistic genotyping.

In most National DNA databases (NDNADB), only single source DNA profiles, and sometimes two-person DNA mixtures, can be searched provided a minimum number of loci (or alleles) is available. DNA profiles that do not meet these criteria (about 14 % of the traces analyzed in Western Switzerland) can be compared locally with candidates upon request from police services, used for one-off search, or remain unused. With the advent of probabilistic genotyping (PG), such complex DNA profiles can be compared to those stored in NDNADB based on likelihood ratios (LRs).

A flexible framework for the design and optimization of water-excitation RF pulses using B-spline interpolation.

Purpose: To implement a flexible framework, named HydrOptiFrame, for the design and optimization of time-efficient water-excitation (WE) RF pulses using B-spline interpolation, and to characterize their lipid suppression performance.

Methods: An evolutionary optimization algorithm was used to design WE RF pulses. The algorithm minimizes a composite loss function that quantifies the fat-water contrast using Bloch equation simulations.

Long-term oncological outcomes of minimally invasive versus open gastrectomy for cancer.

Background: Although laparoscopy is widely used in oncologic digestive surgery, many centers are still reluctant to replace open surgery for gastric cancer treatment, especially in advanced disease. The aim of this study was to assess long-term survival and recurrence in patients after laparoscopic (LG) versus open (OG) oncological gastrectomy, in a tertiary reference center.

Methods: All consecutive patients with gastric adenocarcinoma undergoing curative gastrectomy between December 2007 and December 2021 were retrospectively analyzed.

Hypothalamic deep brain stimulation augments walking after spinal cord injury.

A spinal cord injury (SCI) disrupts the neuronal projections from the brain to the region of the spinal cord that produces walking, leading to various degrees of paralysis. Here, we aimed to identify brain regions that steer the recovery of walking after incomplete SCI and that could be targeted to augment this recovery. To uncover these regions, we constructed a space-time brain-wide atlas of transcriptionally active and spinal cord-projecting neurons underlying the recovery of walking after incomplete SCI.

Differential effects of thiamine and ascorbic acid in clusters of septic patients identified by latent variable analysis.

Background: Thiamine and ascorbic acid have been proposed to mitigate the devastating consequences of sepsis and septic shock. To date, randomized controlled trials have failed to demonstrate a benefit of these therapies and heterogeneity of treatment effect is suspected. In this study, we aimed at assessing the heterogeneity of treatment effect of thiamine (B1) and the combination of B1 plus ascorbic acid (AA + B1) in critically ill patients with sepsis.

Cancer cells impair monocyte-mediated T cell stimulation to evade immunity.

The tumour microenvironment is programmed by cancer cells and substantially influences anti-tumour immune responses. Within the tumour microenvironment, CD8 T cells undergo full effector differentiation and acquire cytotoxic anti-tumour functions in specialized niches. Although interactions with type 1 conventional dendritic cells have been implicated in this process, the underlying cellular players and molecular mechanisms remain incompletely understood.
