Recognizing the severe consequences of alcohol consumption during pregnancy, such as fetal alcohol spectrum disorders (FASDs), the present study explored the role of drinking attitudes, trait impulsivity, and decision-making toward instant gratification in alcohol craving and consumption during pregnancy among mothers of reproductive age. Utilizing participants from Amazon Mechanical Turk ( = 141), we first categorized mothers into three groups: those who neither craved nor consumed alcohol during their last pregnancy, those who craved but did not consume, and those who craved and consumed alcohol. Using binomial logistic regression, we then examined what factors, if any, could differentiate between (a) mothers who craved alcohol during pregnancy and those who did not and (b) mothers who resisted alcohol cravings and those who yielded to them.

Different personal information types are shared at different rates during a social-discounting task. However, it is unclear whether differences in social-discounting rates between different personal information types are related to differences in valuing personal information. To assess the value of personal information more directly, 160 university student participants completed four hypothetical purchase tasks (HPT) for protecting identification, health, security, and financial personal information at 17 ascending price points and a social-discounting task for one of those four different personal information types.

Objective:  This study aimed to investigate whether the calculated predicted value of the estimated glomerular filtration rate from serum creatinine levels (eGFRcreat-PV) from multiple regression equations using the anteroposterior diameter of the renal sinus (APDRS) measured on multidetector row computed tomography (MDCT) axial images and easily obtainable chronic kidney disease (CKD) risk factors (age and body mass index, BMI) is useful for separating CKD stages.

Material And Methods:  The Review Board approved this study, and the additional approval requirement was waived for this retrospective study. We investigated the association between eGFRcreat and age, BMI, and APDRS using stepwise multivariate regression analysis in 98 patients who underwent MDCT and calculated eGFRcreat-PV from the obtained multiple regression equation.

Background: Little is known about whether central airway morphological changes beyond traction bronchiectasis develop and affect clinical outcomes in patients with idiopathic pulmonary fibrosis (IPF). This study aimed to compare central airway structure comprehensively between patients with IPF, subjects with interstitial lung abnormality (ILA), and those without ILA (control) using computed tomography (CT). We further examined the prognostic impact of IPF-specific CT airway parameters in patients with IPF.

Background: Lower skeletal muscle density may reflect muscle adiposity and metabolic dysregulation that potentially impair disease control and lung function independent of high body mass index (BMI) in patients with asthma.

Objective: To investigate whether the lower density of pectoralis muscles (PMs) and erector spinae muscles (ESMs) on chest computed tomography was associated with airway structural changes in patients with asthma.

Methods: Consecutive patients with asthma and healthy controls undergoing chest computed tomography were retrospectively analyzed.

Article Synopsis
  • This study investigates how different airway microbiomes might contribute to mucus plugging in patients with asthma, COPD, and asthma-COPD overlap (ACO).
  • It evaluated the sputum microbiome and mucus plug scores in a sample of patients, finding higher mucus scores linked to specific bacteria in ACO and COPD.
  • The research suggests that the presence of certain bacteria, particularly Proteobacteria and Haemophilus, may play a significant role in mucus plugging, especially in patients with ACO and those with varying levels of eosinophilic inflammation.

Introduction: A knee-ankle-foot orthosis (KAFO) prevents knee buckling during walking and enables gait training for acute hemiplegic stroke patients with severe gait disturbances. Although the goal of gait training with a KAFO is to improve gait ability, that is, to acquire walking with an ankle-foot orthosis (AFO), it is not clear how gait training with a KAFO contributes to improving gait ability. Therefore, this study aimed to investigate the relationship between muscle activities during walking with a KAFO and the improvement of gait ability in hemiplegic stroke patients with severe gait disturbance.

Background: Associations of fractional exhaled nitric oxide (FeNO) with airway wall remodeling and mucus plugs remain to be explored in smokers and nonsmokers with asthma. Ultra-high-resolution computed tomography (U-HRCT), which allows accurate structural quantification of airways >1 mm in diameter, was used in this study to examine whether higher FeNO was associated with thicker walls of the 3rd to 6th generation airways and mucus plugging in patients with asthma.

Methods: The retrospective analyses included consecutive former smokers and nonsmokers with asthma who underwent U-HRCT in a hospital.

Problematic mobile phone use is characterized by its "impulsive" nature; users engage in it despite their negative attitude toward it. From a behavioral-economic perspective, this attitude-behavior discrepancy is generated by competing contingencies that involve smaller-sooner social reinforcers associated with mobile phone use and larger-later prosocial reinforcers potentially compromised by phone use. Based on this conceptualization, the reinforcer-pathology model of problematic mobile phone use is proposed, which posits that such phone use stems from excessive delay discounting of the social and prosocial reinforcers and/or excessive demand for the social reinforcers.

Introduction: The present study attempted to provide a proof-of-concept of usefulness of cluster analysis for identifying distinct and practically meaningful subgroups of drivers who differed in their perceived risk and frequency of texting while driving (TWD).

Method: Using a hierarchical cluster analysis, which involves sequential steps in which individual cases are merged together one at a time based on their similarities, the study first attempted to identify distinct subgroups of drivers who differed in their perceived risk and frequency of TWD. To further evaluate the meaningfulness of the subgroups identified, the subgroups were compared in terms of levels of trait impulsivity and impulsive decision making for each gender.
