BackgroundPostoperative atrial fibrillation (POAF) is a common complication after cardiac surgery, which is associated with age and massive bleeding. However, whether thyroid hormone (TH) level can affect POAF remains controversial.AimTo investigate the occurrence and risk factors of POAF, in particular, the preoperative TH level of patients was introduced into this study as a variable for analysis, and a column graph prediction model of POAF was constructed.MethodsPatients who underwent valve surgery in Fujian Cardiac Medical Center from January 2019 to May 2022 were retrospectively analyzed and divided into POAF group and NO-POAF group. Baseline characteristics and relevant clinical data were collected from the two groups of patients. Independent risk factors for POAF were screened using univariate analysis and binary logistic regression analysis, and a column line graph prediction model was established based on the regression analysis results, and the diagnostic efficacy and calibration of the model were evaluated using the Receiver Operating Characteristic Curve (ROC) and calibration curve.ResultsA total of 2,340 patients underwent valve surgery, excluding 1,751 patients, a total of 589 patients were included, including 89 patients in POAF group and 500 patients in NO-POAF group. The total incidence of POAF was 15.1%. The results of the Logistics regression analysis showed that gender, age, leukocytes and TSH were risk factors of POAF. The area under the ROC curve of the nomogram prediction model for POAF was 0.747 (95% CI: 0.688–0.806, P χ2 = 11.141, P = 0.194 > 0.05, the calibration curve was well fitted.ConclusionThe results of this study show that gender, age, leukocyte and TSH are risk factors of POAF, and the nomogram prediction model has a good prediction effect. Due to the limited sample size and included population, more studies are needed to validate this result.

Previous studies have demonstrated that admission hyperglycemia is a predictor of mortality and poor prognosis in patients with cardiovascular diseases, such as acute myocardial infarction. However, the prognostic value of admission hyperglycemia in patients with acute type A aortic dissection (AAAD) has never been explored. To clarify the association between hyperglycemia and in-hospital outcomes, we retrospectively analyzed 734 patients with AAAD. The interest endpoints were in-hospital mortality rate, the duration of intensive care unit and hospital stays, the occurrence of prolonged mechanical ventilation (PMV), and other complications. All patients were divided into the normal blood glucose group (≤ 140 mg/dL) and hyperglycemia group (140 mg/dL), to compare the in-hospital outcomes rate in the two groups. There were 531 (72.3%) patients with normal blood glucose levels and 203 (27.7%) patients with hyperglycemia. The in-hospital mortality rate was 21.1%, and no statistically significant differences were found between the two groups (20.3% versus 23.2%, P = 0.403). PMV is the most frequent postoperative complication, the incidence of which was significantly higher in the hyperglycemia group than in the normal blood glucose group (59.6% versus 50.8%, P = 0.040). The logistic regression analysis revealed that hyperglycemia (odds ratio (OR): 1.492; 95% CI: 1.014 to 2.197; P = 0.042) was an independent risk factor for PMV after adjusting for confounding factors. Age (OR: 1.021; 95% CI: 1.006-1.037; P = 0.007) and body mass index (OR: 1.101; 95% CI: 1.051-1.153; P0.001) were also associated with PMV. In conclusion, our study showed for the first time that a strong correlation between admission hyperglycemia and increased postoperative PMV in patients with AAAD, but not with in-hospital mortality rate.

ObjectiveTo investigate the characteristic changes in the gut microbiota of patients with type A aortic dissection (AAD) and provide a theoretical basis for future microbiome-oriented interventional studies.MethodsHigh-throughput 16S rDNA sequencing was performed on the stool samples of patients with and without (healthy control subjects) AAD. Using alpha and beta diversity analysis, we compared the gut microbiota composition of 20 patients with AAD and 20 healthy controls matched for gender, age, BMI, and geographical region. The accuracy of AAD prediction by differential microbiome was calculated using the random forest machine learning model. Targeted measurement of the plasma concentration of short-chain fatty acids (SCFAs), which are the main metabolites of the gut microbiome, was performed using gas chromatography–mass spectrometry (GC–MS). Spearman’s correlation analysis was conducted to determine the relationships of gut microbiome and SCFAs with the clinical characteristics of subjects.ResultsThe differences in gut microbiota alpha diversity between patients with AAD and the healthy controls were not statistically significant (Shannon index: p = 0.19; Chao1: p = 0.4); however, the microbiota composition (beta diversity) was significantly different between the two groups (Anosim, p = 0.001). Bacteroidota was enriched at the phylum level, and the SCFA-producing genera Prevotella, Porphyromonas, Lachnospiraceae, and Ruminococcus and inflammation-related genera Fenollaria and Sutterella were enriched at the genus level in the AAD group compared with those in the control group. The random forest model could predict AAD from gut microbiota composition with an accuracy of 87.5% and the area-under-curve (AUC) of the receiver operating characteristic curve was 0.833. The SCFA content of patients with AAD was higher than that of the control group, with the difference being statistically significant (p ConclusionTo the best of our knowledge, this is the first demonstration of the presence of significant differences in the gut microbiome of patients with AAD and healthy controls. The differential microbiome exhibited high predictive potential toward AAD and was positively correlated with inflammatory cytokines. Our results will assist in the development of preventive and therapeutic treatment methods for patients with AAD.

Background Stress plays an important role in the pathogenesis of depression through functional changes to the hypothalamic-pituitary-adrenal (HPA) axis, a key output of which is the stress hormone cortisol. But the precise relationship between HPA axis activity and depression remains unclear, in part because mostly cortisol measurement only provides reflect acute or short-term fluctuations. In this study, hair cortisol and its metabolite cortisone were measured in a prospective, pre and post follow-up study of working stress and depressive symptoms in Chinese fishermen. We evaluated HPA activity, work stress, and depression symptoms before and after fishing to determine whether cortisol and cortisone in hair can moderate the work stress and depression symptoms of Chinese fishermen. Methods Hair cortisol, hair cortisone, work stress, and depression were measured in Chinese fishermen (n=229; age 16–65) before and after 1–3 months at sea. A week after the fishermen returned, they provided 2–4 cm hair segments closest to the scalp. We measured hair cortisol and hair cortisone using high-performance liquid chromatography–tandem mass spectrometry. Results The work stress and hair cortisol of fishermen before fishing were significantly higher than those after fishing, while hair cortisone was lower. There was no significant difference in depressive symptoms. Fishermen with low hair cortisol or high hair cortisone were more likely to show depressive symptoms after experiencing stress, and were less likely to show depressive symptoms when faced with lower levels of work stress, consistent with the differential susceptibility model. Limitations The assumption of an average hair growth of 1 cm/month may cause time overlap between pre- and post-fishing, and time error between the hormone data and questionnaire collection. The present study evaluated only two observation points. The use of self-report scales may affect interpretability of the results. Finally, the study used a limited sample of marine fishermen working out of a single location in Hainan province, China. Conclusions Hair cortisol and hair cortisone appear to have a moderating role in the relationship between work stress and depressive symptoms among fishermen, which fits with the differential susceptibility model of depression. However, their mechanisms of moderation are not the same, which may reflect the complexity of physiological indicators.

BackgroundPostoperative delirium (POD) is an acute brain dysfunction that is frequently observed in patients undergoing cardiac surgery. Increasing evidence indicates POD is related to higher mortality among cardiac surgical patients, but the results remain controversial. Moreover, a quantitative evaluation of the influence of POD on hospital days, intensive care unit (ICU) time, and mechanical ventilation (MV) time has not been performed.ObjectiveThis study aimed to evaluate the correlation between POD and outcomes in patients undergoing cardiac surgery by a systematic review and meta-analysis.Materials and methodsA total of 7 electronic databases (Cochrane Library, PubMed, EMBASE, CINAHL Complete, MEDLINE, Wan-fang database, and China National Knowledge Infrastructure) were searched from January 1980 to July 20, 2021, with language restrictions to English and Chinese, to estimate the impact of the POD on outcome in patients who underwent cardiac surgery. The meta-analysis was registered with PROSPERO (Registration: CRD42021228767).ResultsForty-two eligible studies with 19785 patients were identified. 3368 (17.0%) patients were in the delirium group and 16417 (83%) were in the non-delirium group. The meta-analysis showed that compared to patients without POD, patients with POD had 2.77-fold higher mortality (OR = 2.77, 95% CI 1.86–4.11, P < 0.001), 5.70-fold higher MV (>24h) rate (OR = 5.70, 95% CI 2.93–11.09, P < 0.001); and longer MV time (SMD = 0.83, 95% CI 0.57–1.09, P < 0.001), ICU time (SMD = 0.91, 95% CI 0.60–1.22, P < 0.001), hospital days (SMD = 0.62, 95% CI 0.48–0.76, P < 0.001).ConclusionThe synthesized evidence suggests that POD is causally related to the increased risk of mortality, prolonged length of ICU and hospital stay, and a longer duration of MV time. Future research should focus on the interventions for POD, to reduce the incidence.Systematic review registration[www.crd.york.ac.uk/PROSPERO], identifier [CRD42021228767].

A total of 140 patients undergoing MHVR were randomly divided into the experimental group (normal nursing + self-efficacy intervention) or the control group (normal nursing only) based on a random number table. The primary goal was to evaluate the effect of self-efficacy theory on the self-efficacy of postoperative MHVR patients by General Self-Efficacy Scale (GSES). The secondary goal was to assess the improvement of mental health of postoperative patients as well as their pain through Symptom Checklist 90 (SCL-90) and the visual analogue scale (VAS). The incidence of infection during hospitalization was analyzed, as well as the medication compliance of patients during 3-month follow-up after discharge.Results: Finally, 136 patients completed the whole trial. The GSES score of the experimental group was notably superior over the control group (p < 0.001), and the SCL-90 scores were lower over the control group. The VAS score of the experimental group was remarkably lower than that of the control group (p < 0.001). The incidence of infection in the experimental group was lower than that in the control group (p = 0.026). The medication compliance of the experimental group was superior to that of the control group (p = 0.030).Conclusion: Self-efficacy intervention for patients after MHVR could mobilize their self-efficacy, enhance their postoperative medication compliance, and improve their postoperative recovery. This study provides evidence-based medicine (EBM) evidence for the application of self-efficacy theory to postoperative nursing for patients receiving MHVR.Keywords: self-efficacy intervention, mechanical valve replacement, nursing

Objective To determine the safety and efficacy of early postoperative mobilization in patients who have undergone surgical repair of acute type A aortic dissection. Design Randomized controlled trial. Setting Heart Medical Center. Subjects Seventy-seven patients with acute type A aortic dissection were assessed. Intervention Patients were randomly allocated into: (1) the control group (usual care) ( n = 38) and (2) the intervention group (early goal-directed mobilization) ( n = 39). Main Measures The primary outcome was the patient's functional status. The secondary outcomes included vital signs, serious adverse events, muscle strength, intensive care unit-acquired weakness, grip strength, duration of mechanical ventilation, length of stay, readmission rate, and health-related quality of life after 3 months. Results The vital signs of the patients were within the tolerable ranges during the entire intervention. No serious exercise-related adverse events were observed in the intervention group. The Barthel Index score ( P = 0.013), Medical Research Council score ( P = 0.001), grip strength ( P = 0.001), and health-related quality of life ( P = 0.001) were higher in the intervention group. Intensive care unit acquired weakness ( P = 0.019), duration of mechanical ventilation ( P = 0.002), intensive care unit stay ( P = 0.002), and total length of stay ( P = 0.010) were lower in the intervention group. Patients in the intervention group had a higher physical health-related quality of life ( P = 0.015) at 3 months post-surgery. There was no difference in readmission rates. Conclusions Delivery of early goal-directed mobilization in acute type A aortic dissection was safe and facilitated the recovery of daily living ability, shorter hospital stay, and improved quality of life after discharge.

We conducted a prospective, observational study to determine the incidence of feeding intolerance (FI) within seven days of initiating enteral nutrition (EN) in patients undergoing cardiopulmonary bypass (CPB), and to evaluate the association between FI and a poor prognosis. Patients who underwent CPB surgery at Fujian Medical University Union Hospital between March 2020 and June 2020 were enrolled. According to the presence or absence of FI within seven days after EN, patients were divided into FI and non-FI groups. According to the occurrence of a poor prognosis (death, gastrointestinal haemorrhage, acute kidney injury, liver insufficiency, neurological events [cerebral infarction, cerebral haemorrhage, epilepsy], and prolonged mechanical ventilation [>48 hours]), patients were divided into poor prognosis and good prognosis groups. The mean (standard deviation) age of the 237 CPB patients, including 139 men and 98 women, was 53.80 ± 12.25 years. The incidence of FI was 64.14%. There were 152 cases in the FI group and 85 cases in the non-FI group. Multivariate logistic regression analysis showed factors independently associated with poor prognosis after CPB included FI (odds ratio [OR], 2.138; 95% confidence interval [CI], 1.058-4.320), age (OR, 1.033; 95% CI, 1.004-1.063), NYHA class III - IV cardiac function (OR, 2.410; 95% CI, 1.079-5.383), macrovascular surgery (OR, 5.434; 95% CI, 1.704-17.333), and initial sequential organ failure assessment score (OR, 1.243; 95% CI, 1.010-1.530). Thus, the incidence of FI within seven days of EN after CPB was high, which was associated with a poor prognosis.

Marine fishermen experience high levels of environmental and relationship stress and anxiety. The current study explored the role of stress in the relationship between neuroticism and anxiety symptoms among marine fishermen.Participants (fishermen from Tanmen in Qionghai city, Hainan Province) completed three questionnaires: the NEO-Five-Factor Inventory-Neuroticism Subscale (NEO-FFI-N); the Mental Stressor Investigation Questionnaire (MSIQ); and the Mood and Anxiety Symptoms Questionnaire-30-item-Anxious Arousal Subscale (MASQ-D30-AA) within 1 week before embarking on a fishing trip and then again within 1 week after their return to port. The data were subjected to correlational analyses and structural equation modelling.Positive correlations were found between NEO-FF-N (neuroticism) score, MSIQ score (total stress), MSIQ work-relationship score, ship environmental stress score, and MASQ score (anxiety symptoms). Regression analyses showed environmental stress had a significant moderating effect on the relationship between neuroticism and anxiety symptoms, and further analysis showed a mediating effect of work-relationship stress on the relationship between neuroticism and anxiety symptoms.Marine fishermen with high environmental stress had greater anxiety symptoms than those with low environmental stress. Neuroticism in marine fishermen further affects anxiety symptoms by affecting the level of work-relationship stress.

Purpose Postoperative delirium (POD) is a very common and serious neurological complication in patients admitted to the cardiothoracic surgical intensive care unit (CSICU). We aimed to identify a novel potential sleep-based marker for POD and investigate the relevance between atypical sleep and POD. Patients and Methods This was a prospective, observational study of patients admitted to the CSICU between December 2019 and February 2020 at our center. Sleep characteristics from 21:00 on postoperative day 1 to 07:00 on postoperative day 2 were assessed using polysomnography (PSG). POD from the end of PSG monitoring until postoperative day 5 was evaluated using the Confusion Assessment Method for the Intensive Care Unit. Results This analysis included 20 patients admitted to the CSICU. The incidence of atypical sleep was 45.0%. Compared to patients without delirium, those with delirium had less delta power, less percentage REM sleep, and a higher proportion of atypical sleep and REM sleep loss (P < 0.05). Conclusion The presence of atypical sleep and the absence of REM sleep were associated with POD in patients admitted to the CSICU.

Background Neurological complications is a common complication following novel triple-branched stent graft implantation in patients with Stanford type A aortic dissection (AAD). But the incidence and risk factors of postoperative delirium (POD) are not completely clear. The aim of this study was to investigate the incidence and risk factors of POD after novel triple-branched stent graft implantation. Methods An observational study of AAD patients who underwent novel triple-branched stent graft implantation between January 2017 and July 2019 were followed up after surgery. Patients’ delirium was screened by the Richmond Agitation-Sedation Scale and the Confusion Assessment Method for the intensive care unit from the first day after the operation, lasted 5 days. The risk factors of POD were analyzed by the Cox proportional hazard models. Results A total of 280 AAD patients were enrolled in this research, the incidence of POD was 37.86%. Adjusting for age, body mass index, and mechanical ventilation duration, multivariate Cox regression analysis model revealed that non-manual work (adjusted hazard ratio [AHR] = .554; 95% CI: 0.335–0.915; P = .021), Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores > 20 (AHR = 3.359, 95% CI: 1.707–6.609, P P = .017), and more than two types of analgesics and sedatives were independently associated with POD. Conclusions This study showed that risk factors independently associated with POD were APACHE-II score > 20, hypoxemia, and more types of analgesics and sedatives, and non-manual work was the protective factor. Trial registration This study was retrospectively registered in the Chinese Clinical Trial Registry (Registration number: ChiCTR1900022408; Date: 2019/4/10).

Background Emergency surgery for acute type A aortic dissection (AAAD) is associated with a high risk for posttraumatic stress disorder (PTSD), and the risk factors for PTSD symptoms development in AAAD patients of different sexes remain unclear. Objective To identify the risk factors for PTSD symptoms separately in the females and males following AAAD. Methods A sample population of 214 patients who had AAAD surgery was recruited. Patients’ sociodemographic and disease-specific data were collected during hospitalization. Results In this study, PTSD symptoms was present in 22.1% of the male patients and 20.0% of the female patients (P = 0.739). For the male patients with AAAD, PTSD symptoms were significantly positively associated with HADS-D score (P = 0.029), while those with university education and above (P = 0.039), stronger subjective support (P = 0.010) and greater optimism (P = 0.001) had significantly lower possibility for the presence of PTSD symptoms. For the female patients with AAAD, support availability (P = 0.031) was significantly negatively associated with PTSD symptoms while HADS-D score (P = 0.033) was significantly positively associated with PTSD symptoms. Conclusion Risk factors for PTSD symptoms differ in male patients and female patients following AAAD.

Background: Cardiac surgery patients are at a risk of postoperative nausea, vomiting, and aspiration pneumonia, but conventional 4–6-h fasting can exacerbate thirst. Early oral hydration is recommended, but the post-extubation time for intervention remains unclear. This study aimed to investigate the effects of early thirst management on thirst, the oral environment, gastrointestinal adverse reactions, and aspiration pneumonia in cardiac surgery patients.Methods: A total of 84 cardiac surgery patients were randomly divided into two groups for either conventional oral hydration or early oral hydration. The primary outcome was thirst intensity. The secondary outcomes were adverse gastrointestinal reactions (nausea and vomiting), aspiration pneumonia, unstimulated saliva flow rates, salivary pH, oral odor, oral mucosal moisture, and patients' satisfaction. At 1 h post-extubation, patients were evaluated for thirst intensity and intervention readiness. Patients who passed the evaluation were subjected to thirst management. Results: The patient demographic and clinical characteristics did not significantly vary between the groups. The scores for thirst (3.38 versus 8.24，F=306.21, P＜0.001), oral mucosa (2.03 versus 3.90, P＜0.001), halitosis (2.77 versus 3.76, P＜0.001) were significantly lower in the early oral hydration group than in the conventional oral hydration group. The early oral hydration group was associated with significantly higher salivary pH (6.44 versus 0, P＜0.001), unstimulated saliva flow rates (0.18 versus 0, P＜0.001) and patient satisfaction (4.28 versus 3.15, P＜0.001) than the conventional oral hydration group. Gastrointestinal adverse reactions did not significantly vary (7.70% versus 4.88%, P=0.60), and aspiration pneumonia was not observed in both groups.Conclusion: The early oral hydration significantly alleviated thirst, stabilized the oral environment without exacerbating gastrointestinal adverse reactions and aspiration pneumonia, and increased patient satisfaction.Trial registration: Chinese Clinical Trial Registry: ChiCTR2100049206. Registered 25 July 2021.

Background: Medication adherence is crucial for patients with mechanical heart valve replacement. Although families functioning is positively associated with medication adherence, little is known about the underlying mechanisms.Objective: To test whether family functioning affects medication adherence through illness perceptions and whether this mediating effect was moderated by medication literacy.Methods: 319 patients after mechanical heart valve replacement were included in this cross-sectional study from June 2021 to October 2021. Data regarding family functioning, illness perceptions, medication adherence, and medication literacy were collected through questionnaires. The moderated mediation model was examined by Hayes’s PROCESS macro, based on the bootstrapping method.Results: The results revealed illness perceptions partially mediated the association of family functioning on medication adherence [β = 0.08, 95% confidence intervals: (0.04, 0.12)], and this effect was stronger for patients with low medication literacy than those with high literacy [β = −0.36, 95% CI: (−0.50, −0.22)]. Furthermore, the relationship between family functioning and medication adherence was only significant in patients with low medication literacy [β= 0.36, 95% CI: (0.23, 0.50)].Conclusion: The mediating effect of illness perceptions between family functioning and medication adherence was moderated by medication literacy. Efforts to improve medication adherence by targeting at improving family functioning may be more effective when considering illness perceptions, especially for patients with limited medication literacy.

Background: Prolonged mechanical ventilation (PMV) among acute type A aortic dissection (AAAD) may affect the prognosis, but poorly known about the direct economic burden of PMV in patients with AAAD. The present study was contributing to filling this knowledge gap.Methods: This present study was a retrospective cohort study. Age, gender, payment methods, and postoperative complications were matched at a 1:1 ratio by using a propensity score analysis of AAAD patients. The direct economic burden was expressed as the median 1:1 differences of various hospital costs and length of stay (LOS). The Wilcoxon signed-rank tests were used to compare the difference of direct economic burden at mechanical ventilation (MV) and PMV patients.Results: A total of 464 patients, PMV occurred in 142(30.6%) patients, and 218 patients were enrolled in the matched analysis. The estimated total direct economic burden of PMV was $4970.28(PP < 0.05).Conclusions: Postoperative PMV was associated with increased economic burden among AAAD patients. This study emphasizes the need for early detection and management of PMV to reduce the economic burden.

Aim: The aim of the study was to evaluate the relationship between lymphocyte to monocyte ratio (LMR) at admission and in-hospital mortality of patients with acute type A aortic dissection (AAAD). Patients & methods: We enrolled 536 patients with AAAD between June 2013 and December 2017. Patients were divided into two groups: the deceased group and the survival group. Results: In multivariable analysis, the association between LMR and in-hospital mortality was still significant. When the Q4 was set as the reference value, the odds ratios values of Q1, Q2 and Q3 were 4.4 (95% CI: 2.2–8.9; p < 0.001), 1.4 (95% CI: 1.1–3.4; p = 0.03) and 1.7 (95% CI: 0.8–2.9; p = 0.158). Conclusion: Lower LMR may be independently associated with in-hospital mortality in AAAD.

OBJECTIVESTo investigate the rate of returning to work within 12 months after open triple-branched stent graft placement in acute type A aortic dissection (AAAD) patients and the reasons why patients did not return to work.METHODSWe conducted this cohort study of AAAD patients who were discharged alive from the hospital at Fujian Cardiac Center during the period 2013–2018. The collected data included the patients’ baseline characteristics, employment status at 12 months after AAAD and variables classifying the potential reasons for those who did not return to work at 12 months. We applied logistic regression to estimate the factors associated with returning to work at 12 months.RESULTSOne year after AAAD hospitalization, of the 326 AAAD patients, 81 (24.8%) returned to work, 231 (70.9%) did not and 14 (4.3%) died. Among the 231 patients who did not return to work, 105 (45.5%) were unable to work because of AAAD and 36 (15.6%) lost job owing to AAAD. After adjustment for other risk factors, age, female sex, type of work, operating time, aortic cross-clamp time and length of intensive care unit (ICU) stay were still significantly associated with a lower chance of returning to work.CONCLUSIONSLess than 25% of the previously employed patients returned to work at 12 months after AAAD. Older age, female sex, manual or semi-skilled professional work, a longer operating time, a longer aortic cross-clamp time and a longer length of ICU stay were associated with a lower likelihood of returning to work.

Background Neuromuscular electrical stimulation (NMES) is a possible adjunctive therapy applied to cardiac surgery patients to improve physical function, but the results are still controversial. A systematic review and meta-analysis was conducted to investigate the effects of NMES on functional capacity and quality of life (QoL) in cardiac surgery patients. Methods The following databases PubMed, Embase, Medicine, CINAHL, and the Cochrane Central Register of Controlled Trials were searched for the English language from inception up to March 2021. A systematic targeted literature search evaluating the effects of NMES on physical function and QoL in cardiac surgery patients. The effect size of NMES was presented as the mean difference (MD)/standardized mean difference (SMD) and its 95% confidence interval using fixed/random effect models according to heterogeneity. Two reviewers independently screened and appraised each study by using the Cochrane Risk of Bias Tool. Results Six studies were included involving 400 cardiac surgery patients. The meta-analysis showed that NMES had effect on knee extensor strength (SMD=1.68; p=0.05), but had no effects on 6-minute walking distance (MD=44.08; p=0.22), walking speed (MD=0.05; p=0.24), grip strength (MD=3.01; p=0.39), or QoL (SMD=0.53; p=0.19). Conclusions NMES use in cardiac surgery patients is limited by low to moderate quality. Existing evidence shows that NMES is safe and effective for improving knee extensor strength.

BACKGROUND Surgery is the primary option of acute type A aortic dissection (AAAD) treatment. However, the unique traumatic stress of cardiovascular disease and surgery brings physical and psychological suffering to the patients and causes post-traumatic stress disorder (PTSD). The aim of this study was to investigate the rate of PTSD in AAAD patients after surgery and identify the risk factors of this complication. METHODS A prospective cohort design was used. All patients who underwent AAAD surgery from September 2017 to June 2019 were included. Resilience, anxiety, and depression level were assessed before patients discharged from the hospital. Additionally, the PTSD symptoms were assessed three months after discharge from hospital. The data were analyzed by SPSS 24.0 (IBM, Armonk, NY, USA) and P

As a new surgical method for older adults with cardiac insufficiency, transapical mitral valve clamp surgery requires the cooperation of practitioners across multiple disciplines to ensure appropriate treatment and nursing care. This study aimed to explore the utility of a multidisciplinary team nursing model in the clinical treatment and nursing care of patients undergoing transapical mitral valve clamping.Our sample of ten patients included four men (40%) and six women (60%), with a mean age of 71.4 ± 5.2 years. The multidisciplinary team comprised nurses that specialized in severe illness, cardiac health, rehabilitation, psychology, nutrition, and pain. The team engaged in comprehensive discussions regarding problems specific to the patients undergoing transapical mitral valve surgery, allowing them to formulate individualized nursing measures and implement precise policies.No serious postoperative complications occurred in any of the ten patients included in this study, and a significant improvement was noted in the cardiac status of all the patients. Color ultrasound findings at discharge indicated that the degree of reflux of all the patients was ≤2+. Among the ten patients, the Activity of Daily Living Scale scores at discharge were significantly higher than before the operation (69.0 ± 4.6 vs. 55.0 ± 5.8). In addition, the 6-min walking test results at discharge were significantly better than those observed before the operation (318.0 ± 21.7 m vs. 295.2 ± 18.4 m).Utilization of a multidisciplinary team allows nurses across various specialties to provide more comprehensive and systematic care for patients undergoing a mitral valve clamping operation, thus promoting patient recovery.RéSUMé: CONTEXTE: en tant que nouvelle méthode chirurgicale pour le traitement de l’insuffisance cardiaque chez les personnes âgées, la chirurgie par pince de la valve mitral aiguë nécessite la collaboration de médecins multidisciplinaires pour assurer un traitement et des soins appropriés. OBJECTIFS: étudier l’application du modèle de soins en équipe multidisciplinaire dans le traitement clinique et les soins aux patients atteints de la valve mitral par pince. MéTHODE: sur 10 patients, 4 hommes (40%) et 6 femmes (60%) ont un âge moyen de 71.4 à 5.2 ans. L’équipe multidisciplinaire est. composée d’infirmiers spécialisés dans les maladies graves, la santé cardiaque, la réadaptation, la psychologie, la nutrition et la douleur. L’équipe a mené une discussion approfondie sur les problèmes spécifiques des patients soumis à une opération de la valve mitral transspiroptérale, a élaboré des mesures de soins personnalisées et a mis en œuvre des politiques précises. RéSULTATS: aucune complication postoperatoire grave n’a été observée chez les 10 patients de ce groupe, et les défaillances cardiaques ont été nettement améliorées chez tous les patients. Une double échographie en couleur a montré que le degré de regurgitation mitral était inférieur ou égal à 2+ dans 10 patients sortant de cette étude; Les scores sur l’échelle des activités de la vie quotidienne à la sortie de l’hôpital étaient nettement plus élevés dans 10 cas que dans le cas préopératoire (69.0 ± 4.6 contre 55.0 ± 5.8). En outre, les résultats d’un essai de marche de 6 min à la sortie de l’hôpital étaient nettement supérieurs à ceux observés avant l’opération (318.0 ± 21.7 m contre 295.2 ± 18.4 m). CONCLUSION: le recours à des équipes multidisciplinaires permet aux infirmiers/infirmières spécialisés de fournir des soins plus complets et systématiques aux patients soumis à la chirurgie par compression de la valve mitral, ce qui facilite leur réadaptation.

Background Abnormal body mass index (BMI) has been related to a higher risk of adverse outcomes in patients undergoing cardiac surgery. However, the effects of BMI in patients with acute type A aortic dissection (AAAD) on postoperative outcomes remain unclear. This study aimed to explore the relationships between BMI and in-hospital major adverse outcomes (MAO) in AAAD patients. Methods Patients who underwent AAAD surgery at Cardiac Medical Center of Fujian Province from June 2013 to March 2020 were retrospectively evaluated. They were divided into three groups on the basis of Chinese BMI classification established by the World Health Organization: normal weight group (BMI 18.5–23.9 kg/m2), overweight group (BMI 24–27.9 kg/m2), and obese group (BMI >28 kg/m2). Patients’ baseline characteristics, preoperative, operative, and postoperative data were collected. A multivariable logistic regression analysis model was performed to identify the association between BMI and MAO in AAAD patients. Results Of 777 cases, 31.9% were normal weight, 52.5% were overweight, and 15.6% were obese. A total of 160(20.6%) patients died in-hospital. There was a significant difference between the three groups for MAO (62.9% vs 72.1% vs 77.7%, respectively, P = 0.006). The incidence of postoperative complications did not differ among the three groups, except for postoperative bleeding, and prolonged mechanical ventilation, the proportion of which were higher in the overweight and obese groups. Besides, multivariable logistic regression analysis demonstrated that a higher risk of MAO in the overweight [odds ratios (ORs):1.475, 95%CI:1.006–2.162], and obese patients (ORs:2.147, 95%CI:1.219–3.782) with reference to the normal weight patients, and age, white blood cell, prior stroke and cardiopulmonary bypass time were also associated with in-hospital MAO (P Conclusions BMI is independently associated with higher in-hospital MAO in patients who underwent AAAD surgery.

Background: Abnormal body mass index (BMI) has been related to a higher risk of adverse perioperative outcomes in patients undergoing cardiac surgery. However, the effects of BMI in patients with acute type A aortic dissection (AAAD) on postoperative outcomes remain unclear. The aims of this study were to explore the relationships of BMI and postoperative early adverse outcomes in AAAD patientsMethods: Patients who underwent AAAD surgery at Fujian Province Cardiac Medical Research Center from June 2013 to March 2020 were retrospectively evaluated. They were divided into three groups on the basis of Chinese BMI classification established by the World Health Organization: normal group (BMI 18.5-23.9 kg/m2), overweight group (BMI 24-27.9 kg/m2), and obesity group (BMI > 28kg/m2). Preoperative, intraoperative, and postoperative data were collected. Multivariable and univariable logistic regression analysis models were performed to identify whether BMI was independently associated with postoperative adverse outcomes.Results: Of 777 cases, 31.9% were normal weight, 52.5% were overweight, and 15.6% were obese. The percentage of prolonged mechanical ventilation (44.9% vs 55.8% vs 66.1%, respectively; P PP

Objective The purpose of this study was to explore the value of continuous nursing in patients after cardiac valve replacement. Methods The clinical data of 116 patients after cardiac mechanical valve replacement from January 2017 to January 2018 were analysed retrospectively. According to the nursing mode, the patients were divided into two groups: the continuous nursing group (group A, n = 56) and the conventional nursing group (group B, n = 60). Results The continuous nursing group exhibited significantly decreased SAS and SDS scores 1 year after surgery compared to the preoperative SAS and SDS scores(P P Conclusion Continuous nursing improves patient compliance with treatment and reduces the occurrence of postoperative anticoagulation complications. The patient also receives proper psychological evaluations, which relieve patient anxiety and depression.

Perceived social support (PSS) has been shown to be positively related to self-reported quality of life (QoL) as well as to emotion regulation strategy. In the present study, we compared a QoL index between Chinese fishermen (N = 507) and local villagers (N = 192) and examined whether PSS moderates the relationship between emotion regulation and QoL in our sample of Chinese ocean-going fishermen. Fishermen’s QoL was found to be poorer than that of local villagers. Structural equation modeling (SEM) confirmed that cognitive reappraisal of emotion regulation had a positive predictive effect on QoL, while expression suppression of emotion regulation had a negative predictive effect on QoL. Using, latent moderated structural equations (LMS), we further confirmed that PSS moderates the relationship between emotion regulation and QoL. Simple slope analysis revealed that emotional regulation can predict QoL in a high-PSS context but not in a low-PSS context.

Background Guidelines recommend a clear liquid fasting time of 2 h before surgery, which is often exceeded, leading to adverse reactions (ARs) such as discomfort, thirst, and dehydration. We assessed the gastric contents and ARs after oral glucose water administration 1 h prior to surgery in children with cyanotic congenital heart disease (CCHD). Material/Methods This was a non-inferiority randomized controlled trial of children with CCHD enrolled at the Fujian Medical University Union Hospital from 09/2014 to 05/2017 and randomized to receive oral glucose water (10 g of glucose in 100 ml of warm water, 5 ml/kg) 2 h (2-h group, n=174) or 1 h (1-h group, n=170) before surgery. The primary endpoint was gastric volume. Secondary endpoints included pH of gastric content, preoperative blood glucose, and risk factors for aspiration pneumonia. Pre- and intraoperative ARs were recorded. Results The 1-h group showed smaller gastric content volumes (0.34±0.35 (95% CI: 0.29–0.39) vs. 0.43±0.33 (95% CI: 0.38–0.48) ml/kg, t=2.55, P

Markers of prothrombotic state and inflammation are associated with the prognosis of patients with acute type A aortic dissection (AAAD). However, it is unclear that the relationship between these biomarkers and their combined impact on risk stratification. The present study evaluated the prognostic value of platelet counts, lymphocyte to neutrophil ratio (LNR), and lymphocyte to monocyte ratio (LMR), alone and in combination. A retrospective analysis of clinical data of 744 AAAD patients was conducted to identify whether these biomarkers were related to the 30-day mortality risk. A Kaplan-Meier analysis and log-rank test were used to compare survival between groups. A Cox hazard regression multivariable analysis was performed for 30-day mortality. Individual biomarker (platelet count, LNR, or LMR) was unable to predict 30-day mortality. However, combinations of all three biomarkers provided additive predictive value over either marker alone, the receiver operating characteristic (ROC) model had a prediction probability of 0.739 when platelet counts, LNR, and LMR were included. Cox hazard regression multivariable analysis showed that combinations of all three biomarkers were the strongest predictor of 30-day mortality (p<0.021). Combined with these three easily measurable biomarkers at admission, they could help identify AAAD patients with a high risk of 30-day mortality.

To analyze the risk factors of delirium in patients in cardiac surgery intensive care unit (CSICU).A prospective observational study was performed. Patients admitted to CSICU of Fujian Medical University Union Hospital from March to August in 2017 were enrolled. The combination of the Richmond agitation sedation scale (RASS) and the ICU-confusion assessment method (CAM-ICU) were used to evaluate delirium. The patient was assessed on the second day after CSICU admission, twice a day, the evaluation was stopped, and the follow-up observation was terminated after the patient was discharged from CSICU. The patients were divided into two groups according to whether delirium occurred in CSICU. The general and clinical treatment data (including condition, operation, anesthesia and CSICU treatment) of the two groups were compared. The related factors of delirium were identified by univariate analysis and multifactor Logistic regression analysis.A total of 318 cases were included in this study. Among them, 93 cases had delirium and the incidence of delirium was 29.2%. It was shown by univariate analysis that age, history of hypertension, type of surgery, surgical procedure, American Society of Anesthesiologists (ASA) anesthesia classification, usage of propofol, plasma transfusion, red blood cells, platelet transfusion, blood loss, operative time, cardiopulmonary bypass (CPB) time, myocardial block time, acute physiology and chronic health evaluation II (APACHE II), duration of mechanical ventilation, the length of intensive care unit (ICU) stay, postoperative usage of diazepam, midazolam, fentanyl, morphine, chlorpromazine, etc. which were related to delirium, and occupation (on-the-job or self-employed), medical insurance (city or provincial medical insurance), education (primary to junior high school, high school or above) could reduce the risk of delirium. Colinearity diagnosis was performed on variables with statistically significant differences, and variables with variance expansion factor (VIF)3 were included in multivariate Logistic regression analysis. The results showed that age, education level, type of surgery, ASA classification, CPB time, APACHE II, ICU mechanical ventilation time, and post operation usage of midazolam were independently related to delirium [age: odds ratio (OR) = 1.625, 95% confidence interval (95%CI) = 1.303-2.026; education level: OR = 0.293, 95%CI = 0.171-0.504; type of surgery: OR = 2.194, 95%CI = 1.052-4.576; ASA classification: OR = 1.916, 95%CI = 1.032-3.559; CPB time: OR = 2.125, 95%CI = 1.105-4.088; APACHE II: OR = 2.091, 95%CI = 1.005-4.349; ICU mechanical ventilation time: OR = 1.943, 95%CI = 1.269-2.975; midazolam: OR = 2.653, 95%CI = 1.328-5.299; all P0.05], among which, high education level has a good protective effect on delirium.Age, type of surgery, ASA classification, CPB time, APACHE II, ICU mechanical ventilation time, post operation usage of midazolam were independent risk factors for delirium, and high education level had a good protective effect. Among them, the educational level, CPB time, duration of mechanical ventilation, and midazolam are intervention factors. In clinical treatment, not only the risk factors should be identified, but also intervention should be taken to prevent the occurrence of delirium.

This study examined pathways of influence between work stress, depressive symptoms, nicotine dependence, expressive suppression, and cognitive reappraisal in fishermen with smoking habits in Qionghai, Hainan province, China (N = 1068). These fishermen responded to multiple assessments a week before leaving on a deep-sea fishing trip, including a Mental Stressor Investigation Questionnaire (MSIQ), the Center for Epidemiological Studies Depression Scale (CES-D), the Russell Reason for Smoking Questionnaire (RRSQ), and an Emotion Regulation Questionnaire (ERQ). Structural equation modeling (SEM) analyses of the collected data in Mplus 7 showed that work stress and nicotine dependence were independent predictors of depressive symptoms. The relationship between work stress and depressive symptoms was found to be partially mediated by nicotine dependence and be moderated by cognitive reappraisal. The evidence suggests it advantageous to examine the need of work stress, nicotine dependence, and cognitive reappraisal when attempting to understand depressive symptoms in fishermen with a smoking habit. These findings suggest that improving nicotine dependence through work stress management and training in cognitive reappraisal could be utilized as effective modalities for improving depressive symptoms.

Since mechanical ventilation after cardiac surgery increases the risk of ventilator-associated pneumonia (VAP), we conducted a prospective randomized controlled trial to investigate the effect of preoperative 0.2% chlorhexidine on postoperative VAP. Ninety-four patients scheduled for heart surgery were randomized to a chlorhexidine group (N = 47) or control (saline) group (N = 47). On the day before surgery, patients gargled three times with 0.2% chlorhexidine or saline 30 min after each meal and 5 min after teeth brushing at bedtime. VAP occurred in 8.5% of the chlorhexidine group and in 23.4% of the controls. Preoperative chlorhexidine mouthwash reduced the incidence of postoperative VAP significantly.
