Objective: To implement early rehabilitation interventions by physical therapists is recommended. However, the effectiveness of early rehabilitation for severe coronavirus disease 2019 (COVID-19) patients in the prevention of post-intensive care syndrome (PICS) is unclear. We analyzed a multicenter prospective observational study (Post-Intensive Care outcomeS in patients with COronaVIrus Disease 2019) to examine the association between early rehabilitation interventions and PICS physical impairment. Methods: An analysis was performed on COVID-19 patients who were admitted to intensive care units (ICUs) between March 2020 and March 2021, and required mechanical ventilation. The primary outcome was the incidence of PICS physical impairment (Barthel Index≤90) after one year. Multivariate logistic regression analysis was used to estimate the association between early rehabilitation interventions and PICS physical impairment by adjusting ICU mobility scale (IMS) during seven-day following ICU admission, and clinically relevant risk factors. Results: The analysis included 259 patients, 54 of whom developed PICS physical impairment one year later. In 81 patients, physical therapists intervened within seven days of ICU admission. There was no significant difference in mean IMS by day seven of admission between the early and non-early rehabilitation patients (0.70 and 0.61, respectively). Multivariate logistic regression analysis showed that early rehabilitation interventions were significantly associated with a low incidence of PICS physical impairment (odds ratio, 0.294; 95% confidence interval, 0.123–0.706; p=0.006). Conclusion Early rehabilitation interventions by physical therapists were an independent factor associated with the decreased development of PICS physical impairment at one year, even though early rehabilitation had no significant effect on IMS.

A 67-year-old male was referred to our department for surgical treatment of a left ventricular mass after myocardial infarction. The left ventricular aneurysm was 50×20 mm and the papillary muscles were close to each other. To avoid displacement of the papillary muscles and its effect on the mitral valve, a double-patch closure was performed. A bovine pericardial patch was placed on the endocardial side and a Dacron patch on the epicardial side, and fibrin glue was injected between the two patches. Mitral valvuloplasty and coronary artery bypass grafting were also performed, and the patient had an uncomplicated postoperative course and was discharged home on the 27th postoperative day. Histopathological findings showed no myocardial cells in the wall of the mass, and a diagnosis of pseudoaneurysm was made. Double-patch closure is considered effective for left ventricular masses with a large opening and close proximity to the papillary muscle, as in this case.

Purpose: Patients with diabetes mellitus (DM) often exhibit refractory erectile dysfunction (ED). Red-light-controllable nitric oxide donor (NORD-1) and red-light irradiation have successfully enhanced erectile function in intact rats. In this study, we investigated whether the combination of NORD-1 and red-light irradiation effectively treated ED in streptozotocin (STZ)-treated rats with DM. Materials and Methods: Seven-week-old male Sprague-Dawley rats were used in this study. Rats in the DM and sham groups received intravenous STZ (50 mg/kg) and saline, respectively. One week after treatment, the blood glucose level of rats in the DM group was >250 mg/dL. Five weeks after the treatment, we performed a functional study by measuring intracavernous pressure (ICP) under cavernous nerve stimulation before and after NORD-1 treatment with and without light irradiation. Additionally, we performed an isometric tension study using the corpus cavernosum of rats treated with NORD-1 or the control compound, SiR650. Results: The ICP/mean arterial pressure (MAP) ratio was significantly lower in the DM group than in the sham group before and after NORD-1 treatment without light irradiation (both p<0.05). After NORD-1 treatment with light irradiation, the ICP/MAP ratio in the sham and DM groups was significantly enhanced than before and after NORD-1 treatment without light irradiation (all p<0.05). The ICP/MAP ratio in the DM group after NORD-1 with light irradiation was similar to that in the sham group under normal conditions before NORD-1 treatment. Moreover, the systemic blood pressure was not affected by NORD-1 or light irradiation. In the tension study, the corpus cavernosum of rats treated with SiR650 was not changed by red light in the sham or DM groups. However, the rats treated with NORD-1 were strongly relaxed by red light in both groups. Conclusions NORD-1 and red-light irradiation could improve ED in the presence of DM without lowering blood pressure.

INTRODUCTION

Virtual learning is the new normal brought about by the pandemic in the field of education. Consequently, students are compelled to have increased exposure to electronic screens. With digital eye strain caused by increased exposure to gadgets, this study will look for a correlation between exposure to electronic screens and the severity and frequency of headaches and migraines among students studying online.

This study aims to gain an understanding of the average exposure of students to electronic screens and if there is a high frequency of migraine due to this increased exposure so that school administrators are aware of this; and in turn, to serve as a stepping stone for future studies in the same field of research.

This study will make use of an observational comparative design also known as a cross-sectional descriptive study in order to look into the proportion of students affected by such a phenomenon at one point in time. The chosen study population will consist of medicine students currently enrolled in the University of Santo Tomas, Faculty of Medicine and Surgery. The study will make use of questionnaires in order to gather data from the sample population.

Our research study indicates a significant direct correlation as evidenced by both the Pearson correlation coefficient of 0.386 and the p-value of 0.050 between electronic screen exposure and migraine frequency/severity among UST medicine students engaged in online distance learning.

While this correlation underscores the potential health impact of prolonged screen time, the moderately low association suggests a need for cautious interpretation. Other factors explored, such as gender and year level, exhibited positive correlations of 0.283 and 2.955, respectively, but did not reach statistical significance, possibly due to the small sample size limiting the depth of analysis.

Our study highlights a significant correlation between screen time exposure and migraine severity, suggesting the need for schools adopting online or hybrid setups to consider screen hours in their policies. Given the emergence of online learning environments, these factors require careful consideration. While exploring additional factors like gender and year level, limited sample size hindered conclusive findings. Future research should focus on increasing sample size and investigating variables such as screen time quality, exposure environment and participant demographics to better understand the primary causes predisposing individuals to migraine without aura.

Objective:To explore the application value of echocardiography in the management of pediatric mitral valve replacement.Methods:Thirty-three children who underwent mitral valve replacement at Union Hospital Tongji Medical College Huazhong University of Science and Technology from January 2009 to June 2023 were retrospectively analyzed. Clinical data and preoperative and postoperative echocardiographic data were collected. The differences in ultrasound parameters among preoperative，1-week postoperative，1-month postoperative and 1-year postoperative were compared.Results:Of the 33 children，there were 4 cases（12.12%）of mitral stenosis，33 cases（100%）of mitral regurgitation and 4 cases（12.12%）of mitral stenosis combined with regurgitation. Mechanical valve replacement was performed in 30 cases（90.91%）and bioprosthetic valve replacement in 3 cases（9.09%）. Compared with the preoperative period，the left atrial internal diameter and left ventricular end-diastolic internal diameter were significantly reduced at 1-week postoperatively，1-month postoperatively，and 1-year postoperatively，respectively（all P <0.05）.The left ventricular mass was significantly reduced and the left ventricular end-diastolic sphericity index was significantly increased（both P < 0.05）at 1-month postoperatively compared with preoperatively. The left ventricular ejection fraction was significantly higher at 1-year postoperatively compared with 1-week postoperatively（ P <0.05）. Conclusions:After pediatric mitral valve replacement，the left ventricular dimensions decrease，and cardiac function progressively recovers. Echocardiography is an essential tool for accurate preoperative assessment and postoperative follow-up in pediatric mitral valve replacement.

Objective:To evaluate the left ventricular（LV）function in heart transplant（HTx）patients with post-transplant diabetes（PTDM），and to examine the relevance of PTDM and LV function to the patient's prognosis.Methods:Two hundred and thirteen adult HTx patients who underwent echocardiography at Union Hospital，Tongji Medical College，Huazhong University of Science and Technology between January 2018 and January 2022 were prospectively included. The patients were divided into PTDM group（ n=86）and Non-PTDM group（ n=127）. LV function parameters were acquired using conventional and two-dimensional speckle-tracking echocardiography（2D-STE），and were compared between the two groups. The primary endpoints included all-cause mortality or transplant-related readmission. Results:Compared with Non-PTDM group，the LV mass of PTDM group was higher，the LV ejection fraction，LV global longitudinal strain（GLS），peak systolic global longitudinal strain rate，and early diastolic global longitudinal strain rate（dGLSr）were lower（all P＜0.05）. After a median follow-up period of 37.6（29.3）months，27 patients experienced clinical events. A multivariate analysis revealed that PTDM（ HR=2.198，95% CI=1.018-4.743， P=0.045）and low GLS（ HR=6.456，95% CI=2.889-14.426， P＜0.001）were independent predictors of adverse clinical events after adjustment for dGLSr，body mass index and age. After subdividing the two groups into 4 subgroups by the cutoff value of GLS（16.5%），the prognosis was worst for HTx patients with PTDM and low GLS. Conclusions:HTx patients with PTDM have worse LV systolic and diastolic function than those without PTDM. Management of HTx patients with PTDM may be improved using GLS guidance.
