Clinical Significance of Action Research-Based Seamless Care to Improve Imaging Efficiency and Patients' Cognition, and Alleviate Patient Anxiety.

Objective: The present study was undertaken to assess the clinical significance of action research-based seamless care to improve imaging efficiency and alleviate patient anxiety. Methods: A total of eighty patients who underwent imaging examinations in our hospital between May 2019 and November 2020 were recruited for this study. The patients were randomly assigned to two groups: the control group receiving routine care and the observation group receiving seamless care based on action research. The random assignment was conducted using a simple random sampling technique, ensuring an equal allocation of participants to each group at a 1:1 ratio, resulting in 40 cases in each group. Outcome measures included imaging examination duration, mean nursing duration, examination cognition, and negative emotion scores. Results: Seamless care provided shorter imaging examination duration and nursing duration, and better ensured uneventful examinations than routine care (P<0.05). Patients given seamless care exhibited higher examination cognition versus those receiving routine care (P<0.05). Seamless care offered more mitigation of negative emotions for patients than routine care (P<0.05). Conclusion: Action research-based seamless care effectively improves imaging efficiency and patients' awareness of imaging examinations and contributes to alleviating patients' adverse events.

The use of high-sensitivity cardiac troponin T and creatinine kinase-MB as a prognostic markers in patients with acute myocardial infarction and chronic kidney disease.

Background: High-sensitivity cardiac troponin T (hs-cTnT) and creatine kinase (CK)-MB are the most commonly used biomarkers for the diagnosis and prognosis of acute myocardial infarction (AMI). Chronic kidney disease (CKD) often leads to elevated hs-cTnT levels in non-AMI patients. However, studies comparing the prognostic value of both hs-cTnT and CK-MB in patients with AMI and CKD are lacking.Methods: We conducted a retrospective study on AMI patients diagnosed between January 2015 and October 2020. Patients were categorized based on renal function as normal or CKD. Peak hs-cTnT and CK-MB levels during hospitalization were collected, and their diagnostic value was evaluated using receiver operating characteristic (ROC) curves. The impact on in-hospital mortality was analyzed using multivariate logistic regression. The relationship between the hs-cTnT/CK-MB ratio and in-hospital death was examined using a restricted cubic spline (RCS) curve.Results: The study included 5022 AMI patients, of whom 797 (15.9%) had CKD. The AUCs of Hs-cTnT and CK-MB were higher in the CKD group [0.842 (95% CI: 0.789-0.894) and 0.821 (95% CI: 0.760-0.882)] than in the normal renal function group [0.695 (95% CI: 0.604-0.790) and 0.708 (95% CI: 0.624-0.793)]. After full adjustment for all risk factors, hs-cTnT (OR, 2.82; 95% CI, 1.03-9.86; p = 0.038) and CK-MB (OR, 4.91; 95% CI, 1.54-14.68; p = 0.007) above the cutoff values were independent predictors of in-hospital mortality in patients with CKD. However, in patients with normal renal function, only CK-MB above the cutoff (OR, 2.45; 95% CI, 1.02-8.24; p = 0.046) was a predictor of in-hospital mortality, whereas hs-cTnT was not. There was an inverted V-shaped relationship between the hs-cTnT/CK-MB ratio and in-hospital mortality, with an inflection point of 19.61. The ratio within the second quartile (9.63-19.6) was an independent predictor of in-hospital mortality in patients with CKD (OR 5.3, 95% CI 1.66-16.86, p = 0.005).Conclusions: Hs-cTnT independently predicted in-hospital mortality in AMI patients with CKD, whereas its predictive value was not observed in patients with normal renal function. CK-MB was an independent predictor of in-hospital mortality regardless of renal function. Moreover, the hs-cTnT/CK-MB ratio may aid in risk stratification of AMI patients with CKD.

Ticagrelor versus Clopidogrel in Patients with Severe Renal Insufficiency Undergoing PCI for Acute Coronary Syndrome.

Background: Current guidelines recommend the use of potent antiplatelet agents in patients undergoing percutaneous coronary intervention (PCI) following an acute coronary syndrome (ACS). However, data about optimal platelet inhibition in severe renal insufficiency patients are scarce. The purpose of this study is to determine if ticagrelor is more effective than clopidogrel in patients with ACS and severe renal insufficiency treated with PCI. Methods: We retrospectively enrolled patients with ACS and severe renal insufficiency (eGFR ≤ 30 ml/min·1.73 m2 or dialysis) who underwent PCI at our hospital between January 2015 and March 2020. We used the adjusted Cox proportional hazards models to analyze the 1-year outcome endpoints, including the primary endpoint (the composite of cardiovascular death, recurrence of MI, or nonfatal ischemic stroke), death from any cause, and bleeding events (Bleeding Academic Research Consortium, BARC criteria). Results: A total of 276 patients with ACS and severe renal insufficiency who were treated with PCI with ticagrelor (n = 108) or clopidogrel (n = 168) were included in the study. After adjustment, there was no statistical difference in risk of the primary endpoint (HR, 0.78; 95% CI, 0.46-1.33; P=0.367) and death from any cause (HR, 0.86; 95% CI, 0.38-1.89; P=0.708) in the ticagrelor group against the clopidogrel group. However, the risk of total bleeding was significantly higher in the ticagrelor group (HR, 3.01; 95% CI, 1.81-5.62; P=0.01). Subgroup analysis according to the confounders did not identify any significant subgroup heterogeneity. Conclusion: Ticagrelor did not improve the major adverse cardiovascular events and all-cause mortality when compared to clopidogrel, but significantly increased the risk of bleeding in Chinese patients with ACS and severe renal insufficiency undergoing PCI.

Tazarotene/Betamethasone Dipropionate Cream in Patients with Plaque Psoriasis: Results of a Prospective, Multicenter, Observational Study.

BACKGROUND: Topical agents are still the mainstay for the treatment of mild-to-moderate plaque psoriasis, in which fixed combinations play an important role. Tazarotene/betamethasone dipropionate (Taz/BD) cream is a novel fixed combination approved for treating plaque psoriasis in China, but its efficacy and safety have not been verified in a real-world environment. OBJECTIVES: The primary objective was to investigate the efficacy and safety of Taz/BD cream in treating plaque psoriasis. The secondary objectives were to assess its relapse after discontinuation and the efficacy and safety profiles during retreatment. METHODS: A prospective, multicenter, large-scale observational study was conducted. Adult patients with chronic plaque psoriasis involving <20% of the body surface area were enrolled. Taz/BD cream was applied once daily for 4 weeks. Patients who achieved ≥90% improvement in the Psoriasis Area and Severity Index (PASI) from baseline to week 4 were followed up to investigate relapse after drug withdrawal. Relapsed patients underwent another 4-week treatment. RESULTS: In total, 2,299 eligible patients were enrolled, and 2,095 patients (91.1%) completed the 4-week study. The mean PASI improvement at week 4 was 53.7%, and the PASI 50/75 response rates were 62.5 and 26.8%, respectively. The mean PASI reduction in plaque induration, desquamation and erythema were 58.3, 61.0 and 40.0%, respectively (p < 0.001). Adverse reactions occurred in 445 patients (20.8%) at week 4. The most frequently reported adverse reactions were local skin irritation, including pruritus (10%), pain (6.7%), erythema (6.1%) and desquamation (1.8%). During the post-treatment period, 47 patients (24.0%) relapsed within 8 weeks after drug discontinuation. Forty-five patients were retreated for another 4 weeks, and the PASI 50/75 response rates were 72.7 and 40.9%, respectively. There were no unexpected safety signals during retreatment. CONCLUSION: Taz/BD cream is effective and well tolerated in treating mild-to-moderate plaque psoriasis under near real-world conditions and demonstrates efficacy and safety during retreatment.
