Objective: To realize the changes in pulmonary hypertension (PH) patients' right ventricular function. Methods: A total number of 74 patients with PH were included, and the parameters of standard echocardiographic were measured as well as the strain of peak longitudinal of each segment during the systole of the right ventricle to calculate the global longitudinal strain (LS) during systole of the right ventricular free wall. Results: ① As pulmonary arterial pressure increased, the right ventricular area gradually increased, and the case group showed the decreased right ventricular fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), and tricuspid annular peak systolic velocity (S') (p < 0.05). ⋯ Conclusion: ① LS right ventricular free wall is useful in detecting changes in right ventricular systolic function early on with greater sensitivity than RVFAC, TAPSE, and S'. In addition, increased right ventricular pressure loading can result in a subsequent impairment of right ventricular myocardial mechanics. ② As right ventricular pressure loading increases, right ventricular strain decreases. ③ In mild PH, the right ventricular free wall's. LS is more sensitive than standard measures in spotting early alterations in myocardial mechanics.

Low HbF expression in HbE-β+-thalassemia may lead to misdiagnosis of HbE heterozygosity. We aimed to characterize the β- and α-globin genes and the modifying factors related to HbF expression in patients with an Hb phenotype similar to that of HbE heterozygotes. Furthermore, screening tools for differentiating HbE-β+-thalassemia from HbE heterozygotes have been investigated. ⋯ HbE-β+-thalassemia cannot be disregarded until appropriate DNA analysis is performed, and the detection of α-thalassemia mutations should always be performed under these conditions. An HbE level ≥35.0% may indicate screening of samples for DNA analysis for HbE-β+-thalassemia diagnosis.

This study aims to explore the correlation between central and peripheral thyroid resistance indices and diabetic retinopathy(DR) in patients with type 2 diabetes mellitus (T2DM), so as to provide a clinical basis for the prevention and treatment of diabetic retinopathy. ⋯ The reduction of central and peripheral thyroid hormone sensitivity is an independent risk factor for DR. These results can help predict the risk of the occurrence and development of DR, which may provide a clinical basis for the prevention and treatment of DR in T2DM patients.

To ascertain if postoperative thrombocytopenia following open aortic surgery with a median sternotomy can predict early- and intermediate-term morbidity and mortality. ⋯ Early postoperative thrombocytopenia following type A aortic dissection surgery is a risk factor for morbidity and mortality. Because postoperative thrombocytopenia can indicate a poor prognosis, monitoring early postoperative platelets helps identify individuals who may develop late postoperative problems, which is performed by this affordable biomarker.

Understanding patient and caregiver experience is key to providing person-centered care. The palliative care approach includes holistic assessment and whole-person care at the end of life, that also involves the patient's family and loved ones. The aim of this study was to describe the way that family caregivers experienced patients' deaths during their loved ones' last hospital admission, comparing inpatient palliative care (PCU) and non-palliative care (Non-PCU) units. ⋯ PCU provides a person-centered approach to care at the end of life, optimizing treatment for patients with advanced disease, ensuring effective communication, establishing a satisfactory professional relationship with both patients and their loved ones, and facilitating the farewell process for family caregivers.
