In this paper, we study facial expression recognition (FER) using three modalities obtained from a light field camera: sub-aperture (SA), depth map, and all-in-focus (AiF) images. Our objective is to construct a more comprehensive and effective FER system by investigating multimodal fusion strategies. For this purpose, we employ EfficientNetV2-S, pre-trained on AffectNet, as our primary convolutional neural network.

Introduction: Mental health disorders figure among the many comorbidities of obstructive respiratory diseases. The multisystemic characteristics of chronic respiratory disease and its impact on quality of life could affect depressive and/or anxiety disorders. We aimed to evaluate the association of spirometric indices, ventilatory disorders, and self-reported respiratory diseases with psychiatric disorders considering potential confounders.

Article Synopsis
  • Chronic lung allograft dysfunction (CLAD) is a significant concern for lung transplant patients, prompting the creation of SysCLAD to help predict its onset.
  • Research involved analyzing various factors, including patient health (clinicome), airway microbiota (exposome), and immune responses (immunome), to understand their roles in CLAD development.
  • Findings suggest that exposure to air pollution negatively affects lung function in transplant recipients and highlight potential biomarkers (like MMP-9 and certain immune cells) that could help predict CLAD and improve long-term survival.

Barrier integrity is central to the maintenance of healthy immunological homeostasis. Impaired skin barrier function is linked with enhanced allergen sensitization and the development of diseases such as atopic dermatitis (AD), which can precede the development of other allergic disorders, for example, food allergies and asthma. Epidemiological evidence indicates that children suffering from allergies have lower levels of dietary fibre-derived short-chain fatty acids (SCFA).

Introduction: Emerging evidence suggests that long-term pulmonary symptoms and functional impairment occurs in a proportion of individuals following SARS-CoV-2 infection. Although the proportion of affected patients remains to be determined, physicians are increasingly being confronted with patients reporting respiratory symptoms and impairment beyond the acute phase of COVID-19. In face of limited evidence, the Swiss Society for Pulmonology established a working group to address this area of unmet need and formulated diagnostic and treatment recommendations for the care of patients with pulmonary long COVID (LC).

Article Synopsis
  • Evidence suggests that the lower airway microbiota plays a crucial role in lung health, particularly in lung transplant recipients.
  • Researchers analyzed 234 bronchoalveolar lavage samples and identified four distinct "pneumotypes" which reflect different states of lung microbiota composition post-transplant.
  • The 'balanced' pneumotype is associated with better immune tolerance and lung function, while other pneumotypes linked to potential pathogens are correlated with increased immune response and risks of complications.

The World Health Organization (WHO) recommends countries introduce new anti-TB drugs in the treatment of multidrug-resistant tuberculosis. The aim of the study is to prospectively evaluate the effectiveness of bedaquiline (and/or delamanid)- containing regimens in a large cohort of consecutive TB patients treated globally. This observational, prospective study is based on data collected and provided by Global Tuberculosis Network (GTN) centres and analysed twice a year.

The impact of tuberculosis and of anti-tuberculosis therapy on composition and modification of human lung microbiota has been the object of several investigations. However, no clear outcome has been presented so far and the relationship between M. tuberculosis pulmonary infection and the resident lung microbiota remains vague.

Article Synopsis
  • - Diaphragmatic paresis or paralysis can occur on one side (unilateral) or both sides (bilateral) and can range from no symptoms to severe respiratory failure.
  • - Respiratory tests show reduced pressures and vital capacity, especially when lying down compared to sitting.
  • - Unilateral cases are usually temporary and often occur after surgery, while bilateral cases are more permanent and linked to neuromuscular conditions; treatments may include managing underlying causes, improving overall health, and in some cases, surgical options like diaphragmatic plication.

Background: Allergic skin inflammation often presents in early childhood; however, little is known about the events leading to its initiation and whether it is transient or long-term in nature.

Objective: We sought to determine the immunologic rules that govern skin inflammation in early life.

Methods: Neonatal and adult mice were epicutaneously sensitized with allergen followed by airway allergen challenge.

A combination of targeted molecular methods and phenotypic drug-susceptibility testing is the most widely used approach to detect drug resistance in Mycobacterium tuberculosis isolates. We report the delay in the introduction of an efficient anti-tuberculous drug regimen because of a M. tuberculosis strain displaying a high level of resistance to isoniazid, in the absence of the common mutations associated with isoniazid-resistance, including katG mutations and inhA promoter mutations.

Immune checkpoint inhibitors (ICIs) have been shown to improve overall and progression-free survival in various cancers but have been associated with various immune-related adverse events (IRAEs), including interstitial lung disease, especially organizing pneumonia. We report 2 cases of isolated severe airway disease attributable to ICIs, a rarely reported pattern of lung toxicity. The first patient received nivolumab with or without ipilimumab in a randomized double-blind trial for locoregional metastatic melanoma.

PneumoLaus: Prevalence of Lung Function Abnormalities in a Sample of the General Population of Lausanne Reduced lung function predicts increased mortality. The prevalence of spirometric abnormalities depends on their definition, the references values used and the use or not of bronchodilation. In the PneumoLaus study, conducted between 2014 and 2017 in a sample of the general population of Lausanne, prevalence of chronic obstruction was 3,8 %, of reversible obstruction 2,5 % and of possible restriction 2,2 %.

Obesity hypoventilation syndrome is an underdiagnosed pathology, whose prevalence is increasing due to the progressively higher prevalence of obesity in the general population. Early detection allows early management and lowers the risk of acute exacerbation, hospitalization and mortality. The diagnosis is done by excluding other, pulmonary or extra pulmonary, reasons of hypercapnia; a nocturnal polygraphy is mandatory to diagnose an associated obstructive sleep apnea syndrome.

Lung cancer remains the most common cause of cancer deaths in the world, but its mortality can be significantly reduced by diagnosis and early detection. Computerized resources were developed to assist radiologists in their management of the large volume of thoracic images to be analyzed. Their objective is the detection of pulmonary nodules with high sensitivity and a low rate of false-positives and the ability to differentiate benign and malignant nodules.

The international recommendations of the management of asthma have been modified last years. Several therapies used since long time have no place in the management of moderate asthma today. The use of targeted immunotherapies against phenotypes of asthma are used more and more.
