The Comprehensive Adversity Measure (CAM): A measure of early adversity and its severity.

Background: Early adversity scales often display insufficient content coverage and typically assess the presence of adversity, but not its severity.

Objective: To address some of these limitations, we developed the 13-item Youth and Childhood Adversity Scale. We subsequently revised and expanded the scale regarding content coverage and item wording, resulting in a 22-item version, which we here describe.

Hypercapnia and lung function parameters in chronic obstructive pulmonary disease.

Background: In advanced chronic obstructive pulmonary disease (COPD), hypercapnia may occur due to severe bronchial obstruction with lung hyperinflation. Non-invasive ventilation (NIV) provides the standard of care intended to achieve physiological PCO levels, thereby reducing overall mortality. The present study aimed to evaluate pulmonary function parameters derived from spirometry (forced vital capacity [FVC], forced expiratory volume in 1 s [FEV1]), body plethysmography (residual volume [RV], total lung capacity [TLC]), and lung diffusion capacity for carbon monoxide (single-breath method [DCO-SB], alveolar-volume corrected values [DCO-VA]) as predictors of chronic hypercapnia in patients with advanced COPD.

A cross-national validation of the Internet Severity and Activities Addiction Questionnaire (ISAAQ).

Problematic usage of the internet (PUI) is of increasing concern in a digitalized world. While several screening tools have been developed to assess PUI, few have had their psychometric properties evaluated, and existing scales are also not typically designed to quantify both the severity of PUI and the nature of diverse problematic online activities. The Internet Severity and Activities Addiction Questionnaire (ISAAQ), consisting of a severity scale (ISAAQ Part A) and an online activities scale (ISAAQ part B) was previously developed to address these limitations.

Internet severity and activities addiction questionnaire (ISAAQ): Psychometrics of item response theory and clustering of online activities.

Background: Problematic usage of the internet (PUI) is an umbrella term, referring to a variety of maladaptive online behaviors linked to functional impairment. There is ongoing need for the development of instruments capturing not only PUI severity, but also the online activity types. The Internet Severity and Activities Questionnaire (ISAAQ), previously developed to address this need, required further refinement and validation.

Developmental alcohol exposure impairs synaptic plasticity without overtly altering microglial function in mouse visual cortex.

Fetal alcohol spectrum disorder (FASD), caused by gestational ethanol (EtOH) exposure, is one of the most common causes of non-heritable and life-long mental disability worldwide, with no standard treatment or therapy available. While EtOH exposure can alter the function of both neurons and glia, it is still unclear how EtOH influences brain development to cause deficits in sensory and cognitive processing later in life. Microglia play an important role in shaping synaptic function and plasticity during neural circuit development and have been shown to mount an acute immunological response to EtOH exposure in certain brain regions.

Efficacy and safety of 121 injections of the greater occipital nerve in episodic and chronic cluster headache.

Introduction: Infiltration of the greater occipital nerve (GON) with local anaesthetics and corticosteroids is a treatment option for cluster headache.

Methods: We retrospectively analysed the efficacy and safety of 121 GON injections in 60 patients with episodic or chronic cluster headache over a period of 4 years.

Results: Almost 80% of the infiltrations were at least partially effective (reduction of attack frequency, duration or severity) and 45% resulted in a complete response (no further attacks).
