Objective: Embitterment and post‐traumatic embitterment disorder (PTED) is critical, merging through different cultures. We explored the prevalence and related clinical characteristics of PTED of inpatients in a general hospital in China. Method: Two hundred inpatients (aged 18–65 years) from different departments were recruited by convenient sampling and standardized diagnostic interviews of PTED. Demographic data, Post‐traumatic Embitterment Disorder Self‐Rating Scale (PTED‐21), the Patient Health Questionnaire depression scale (PHQ‐9), Generalized Anxiety Disorder‐7 (GAD‐7) and the Patient Health Questionnaire depression scale (PHQ‐15) were collected on all participants. Results: The prevalence of PTED was 21% (42/200) in inpatients in China; besides, the rate of increased syndromal embitterment is 28% (56/200), including 42 patients diagnosed with PTED. PTED was mainly associated with stressful events, such as illness, work and complicated interpersonal relationships. Rheumatology department and respiratory department have the highest and second highest prevalence of PTED among all departments. PTED‐21 scores were significantly correlated with PHQ‐9, GAD‐7 and PHQ‐15 (all P < 0.01). Conclusions: The present study shows that embitterment is a critical negative emotion in inpatients with somatic illnesses with comorbid depression, anxiety and somatic symptoms. PTED and feelings of embitterment should be given proper attention in diagnosing somatic patients, and it is crucial to enhance PTED screening and intervention in the future. Future intervention studies on post‐traumatic embitterment disorder could be done in general and especially in psychosomatic and somatic medicine. [ABSTRACT FROM AUTHOR]

Separation of acetylene (C2H2) and carbon dioxide (CO2) is of prime importance in the petrochemical industry, but their similarities in molecular size and volatility make it particularly difficult. A desired adsorbent for highly efficient C2H2/CO2 separation should have high selectivity and C2H2 uptake simultaneously, and the introduction of functional groups into MOFs is an effective strategy to achieve this purpose. Herein, we report a titanium‐based MOF material (MIL‐125‐NH2), featuring the suitable pore sizes and amino‐functionalized pore surfaces to show the preferential adsorption of C2H2 over CO2 with both high C2H2 uptake and C2H2/CO2 selectivity. Theoretical simulation results indicate that the preferential C2H2 adsorption is mainly attributed to multiple hydrogen bonding interactions between C2H2 molecule and amino functional groups.

Background: Cognitive impairments are common in asthma, which is a serious global health problem characterized by chronic airway inflammation. However, the underlying neuromechanism is still unclear.Purpose/hypothesis: To investigate the neuromechanism underlying cognitive impairments of asthma. We hypothesized that asthma patients exhibit altered white matter (WM) microstructures, which may contribute to their cognitive impairments.Study Type: Case-control study.Subjects: 37 patients with asthma (14 male) and 31 healthy controls (10 male).Field Strength/sequence: Diffusion tensor imaging (DTI) covering the whole brain was acquired on a 3.0T scanner using a single-shot echo planar imaging sequence.Assessment: A DTI with tract-based spatial statistics (TBSS) approach was used to investigate the whole-brain differences in the WM fractional anisotropy (FA) values.Statistical Tests: Demographic and neuropsychological data were performed using two independent sample t-test or chi-square test or Mann-Whitney rank test. The relationship between cognitive impairments and WM abnormalities was studied using correlation analyses.Results: Impairments of language ability, executive function, and visual-spatial processing and widespread WM disruptions reflected by FA reduction were found in asthma patients. The executive function was related to left forceps major, cingulum, and right uncinate fasciculus, ILF (inferior longitudinal fasciculus) positively (P < 0.05). FA abnormalities were positively correlated with duration of asthma and asthma control test (ACT) scores.Data Conclusion: Asthma patients display multiple cognitive impairments and universally WM integrity disruptions, among which executive dysfunction closely correlates with WM abnormalities.Level Of Evidence: 1 Technical Efficacy: Stage 5 J.
