Fulltext Research on the Impact of Challenge-Hindrance Stress on Employees' Innovation Performance: A Chain Mediation Model

Cai W, Xu C, Yu S, Gong X

Based on the transaction theory of stress and the theory of resource conservation, which introduces knowledge acquisition and intrinsic motivation as mediating variables, a chain mediating model for the influence of challenge-hindrance stress on innovation performance is constructed. Data of 295 samples collected in three stages were used to testify hypothesis. The results confirmed a positive relationship between challenge stress and innovation performance, and a negative relationship between hindrance stress and innovation performance. Intrinsic motivation and knowledge acquisition play a parallel and chain mediating role in the relationship between challenge-hindrance stress and innovation performance. These findings contribute to a deeper understanding of how challenge -hindrance stress affects innovation performance and provide important practical guidance for improving innovation performance.

Every year, over 200 million adults are undergoing noncardiac surgery. These noncardiac surgery patients may face the risk of cardiac mortality and morbidity during the perioperative and recovery periods. Around ten million patients who underwent noncardiac surgery experience cardiac complications within the first 30 days of the postoperative period; the complications are myocardial infarction, cardiac death, and cardiac arrest. This cardiovascular risk is mostly faced by the patients having cerebrovascular or cardiac disease and the patients with the age greater than 50 years. Monitoring and treating cardiac diseases with a suitable biomarker during the perioperative period is necessary for the early recovery of noncardiac surgery patients. This review discussed the risk factors and the key guidelines to avoid the cardiovascular risks during the perioperative period of noncardiac surgery patients. In addition, the biomarkers and identification strategies for cardiac diseases are discussed.
Effects of nutrient ratios on a newly harmful dinoflagellate Heterocapsa bohaiensis: evidence from growth, toxicity and transcriptome analyses

Heterocapsa bohaiensis is a newly identified dinoflagellate species that causes harmful blooms in coastal areas in China, Malaysian, and New Caledonian. These blooms have led to substantial economic losses for local aquaculture. Previous studies have mainly focused on understanding the toxicity of H. bohaiensis. However, the causes of H. bohaiensis blooms remain unknown. In this study, we aimed to ascertain nitrogen (N) and phosphorus (P) requirements for the growth and reproduction of H. bohaiensis. Additionally, we sought to understand the functional mechanisms by comparing the transcriptomes of H. bohaiensis under nutrient-limited conditions and control conditions. The results revealed a wide range of acceptable N:P ratios for H. bohainensis, attributed to a mechanism involving nutrient storage, which allowed H. bohainensis to sustain its growth even when either nitrate or phosphate was depleted. Higher N:P ratios (> 27.5) were more conducive to the growth of H. bohainensis than f/2 medium or low ratios, which is related to the N:P ratios absorbed by H. bohainensis. The toxicity of H. bohainensis was significantly enhanced in N-limited or P-limited states. These findings underscore the significance of the physiological metabolism of H. bohainensis in adapting to environmental stresses induced by human activities and establishing the dominance of blooms.
Rome Foundation-Asian working team report: Asian functional gastrointestinal disorder symptom clusters

Siah KTH, Gong X, Yang XJ, Whitehead WE, Chen M, Hou X, et al.

Gut, 2018 Jun;67(6):1071-1077.
PMID: 28592440 DOI: 10.1136/gutjnl-2016-312852

OBJECTIVE: Functional gastrointestinal disorders (FGIDs) are diagnosed by the presence of a characteristic set of symptoms. However, the current criteria-based diagnostic approach is to some extent subjective and largely derived from observations in English-speaking Western patients. We aimed to identify latent symptom clusters in Asian patients with FGID.
DESIGN: 1805 consecutive unselected patients with FGID who presented for primary or secondary care to 11 centres across Asia completed a cultural and linguistic adaptation of the Rome III Diagnostic Questionnaire that was translated to the local languages. Principal components factor analysis with varimax rotation was used to identify symptom clusters.
RESULTS: Nine symptom clusters were identified, consisting of two oesophageal factors (F6: globus, odynophagia and dysphagia; F9: chest pain and heartburn), two gastroduodenal factors (F5: bloating, fullness, belching and flatulence; F8 regurgitation, nausea and vomiting), three bowel factors (F2: abdominal pain and diarrhoea; F3: meal-related bowel symptoms; F7: upper abdominal pain and constipation) and two anorectal factors (F1: anorectal pain and constipation; F4: diarrhoea, urgency and incontinence).
CONCLUSION: We found that the broad categorisation used both in clinical practice and in the Rome system, that is, broad anatomical divisions, and certain diagnoses with long historical records, that is, IBS with diarrhoea, and chronic constipation, are still valid in our Asian societies. In addition, we found a bowel symptom cluster with meal trigger and a gas cluster that suggests a different emphasis in our populations. Future studies to compare a non-Asian cohort and to match to putative pathophysiology will help to verify our findings.
Rome foundation Asian working team report: Real world treatment experience of Asian patients with functional bowel disorders

BACKGROUND AND AIM: Information on real world treatment experiences of patients with functional bowel disorders is lacking from Asia. This study aimed to describe the medication exposure and treatment satisfaction of patients presenting to gastroenterology clinics across a sampling of Asian cities.

METHODS: From March 2011 to October 2013, adult patients presenting to hospital-based gastroenterology outpatient clinics in 11 cities across Asia, who fulfilled screening criteria for any functional gastrointestinal disorder, were asked to complete a validated culturally adapted translation of the Rome III diagnostic questionnaire, a checklist of medications received in the preceding 3 months and questions on treatment satisfaction.

RESULTS: A total of 1376 patients (female 755, male 621, 41.36 ± 13.25 years) comprising irritable bowel (621, 45.1%), unspecified functional bowel disorder (372, 27.8%), functional constipation (202, 14.7%), functional bloating (144, 10.5%), and functional diarrhea (56, 4.1%) completed the study. Of 1105 patients with a previous consultation, 509 (46.1%) were dissatisfied with their treatment, with ineffective treatment being the commonest reason. Satisfaction with previous consultation was lowest by diagnosis for functional constipation (29.2%), and the most bothersome symptom was straining (37.5%). Of 1046 patients who had taken medications for their gastrointestinal symptoms in the last 3 months, 793 (75.8%) had received two or more drugs. For irritable bowel syndrome patients, treatment with proton pump inhibitors and antispasmodics was recorded in 57% and 31%, with overlapping epigastric pain and heartburn predicting proton pump inhibitors use.

CONCLUSIONS: More attention should be given to treatment gaps with regards to possible under-treatment with antispasmodics in irritable bowel syndrome and to critically evaluating the efficacy of constipation management.
