One of its primary surgical treatments of tricuspid regurgitation is tricuspid valve biological valve replacement. Catheter tricuspid valve-in-valve implantation is a novel interventional alternative for biological valve failure. The non-invasive lung fluid measuring device remote dielectric sensing (ReDSTM) has been increasingly incorporated into clinical practice as a means of monitoring chronic heart failure in recent years. This report describes the process and outcomes of the first instance of perioperative lung fluid volume evaluation following transcatheter tricuspid valve implantation utilizing ReDSTM technology. The patient has a short-term, substantial increase in postoperative lung fluid volume as compared to baseline.

Objective:To investigate the early right heart function management strategy and prognosis after left ventricular assist device(LVAD) implantation in patients with preoperative right ventricular dysfunction.Methods:A retrospective study was conducted. From March 2022 to April 2024, a total of 28 patients with end-stage heart failure underwent LVAD implantation at Nanjing First Hospital and were admitted to the intensive care unit(ICU) after surgery. Among them, patients with preoperative right ventricular dysfunction were enrolled. All patients were implanted with Corheart 6 implantable left ventricular assist device. The clinical data, occurrence of postoperative right heart failure and postoperative survival situations of enrolled patients were collected and analyzed.Results:A total of 12 patients were included in this study, including 11 males and 1 female, the mean age was(58.4±7.6) years old. Upon postoperative admission to ICU, the most commonly used positive inotropic agent was epinephrine(9 cases), followed by dobutamine(8 cases). By the second day after surgery, the most frequently utilized vasoactive medications were epinephrine and phosphodiesterase type Ⅲ inhibitors, both with 9 cases of usage. None of the enrolled patients utilized temporary mechanical circulatory assist devices. The LVAD pump speed of the patients enrolled in the study was set at approximately 2 700 revolutions per minute, and the pump flow was approximately 3 liters per minute. During the first two days after the operation, the fluid balance of the enrolled patients ranged from(-523.4±775.6)ml to(-1 248.0±1 023.9)ml. At 48 h following the operation, the mean pulmonary artery pressure(MPAP)[(26.2±4.8) mmHg vs.(32.1±6.5) mmHg(1 mmHg=0.133 kPa), P=0.042] and the pulmonary artery wedge pressure(PAWP)[(15.6±5.5)mmHg vs.(24.9±5.9) mmHg, P=0.003) ] of the enrolled patients were significantly decreased compared to preoperative levels, while the cardiac index(CI) was significantly improved[(2.7±0.2)L·min -1·m -2 vs.(2.1±0.5)L·min -1·m -2,P=0.024]. Echocardiography showed that the left atrial diameter(LAD)[(51.5±7.6)mm vs.(57.2±9.0)mm, P=0.005] and left ventricular end diastolic diameter(LVDd)[(73.5±11.5)mm vs.(78.3 ± 12.3)mm, P=0.012) ] were significantly reduced post LVAD implantation as compared to before LVAD implantation, while there was no significant difference in tricuspid annular plane systolic excusion(TAPSE). Postoperative total bilirubin(TBIL) decreased significantly compared to preoperative levels[(15.5±5.0)μmol/L vs.(27.5±17.0)μmol/L, P=0.038]. Three patients experienced right heart failure after the LVAD implantation, with an incidence rate of 25%. Nevertheless, the right heart failure was rectified during the ICU treatment period. The mean ICU treatment time for all enrolled patients was(8.6±2.9) days, the average postoperative hospital stay was(24.3±4.8) days. All enrolled patients survived at 3 months after LVAD implantation. Conclusion:Despite the presence of right ventricular dysfunction in patients before LVAD implantation, with strict fluid management, reasonable LVAD parameters, and appropriate vasoactive drugs, they are able to smoothly pass through the perioperative period, achieve the goals of left ventricular decompression, increase cardiac output, improve perfusion of the end organs, and obtain favorable short-term therapeutic effects.

Objective:To explore the impact of lifestyle on TCM constitutions among female medical workers at Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine using questionnaires; To provide references for optimizing their health management.Methods:A cross-sectional study was conducted. A total of 500 female medical workers were randomly selected from Xiyuan Hospital from April to December 2022 to complete the questionnaires. The relationship between lifestyle and constitutions of female medical workers was analyzed.Results:A total of 457 cases completed the questionnaires. Among the 9 constitutions, 102 people (22.32%) had a peaceful constitution, while 355 people (77.68%) had a biased constitution; the top three biased constitutions were qi stagnation constitution 90 people (19.69%), yang deficiency constitution 83 people (18.16%), and phlegm-dampness constitution 56 people (12.25%). The factors that influenced physical constitutions according to the severity of lifestyle were: sleep, diet, mood, exercise, labor, environment, children, and education.Conclusions:Female medical workers have a high proportion of biased constitution, and the main types of biased constitution are qi stagnation constitution, yang deficiency constitution, and phlegm-dampness constitution. According to the existing biased constitution, targeted adjustments and interventions are carried out, and it is of great significance to protect and care for the health of female medical workers from the concept of preventive treatment of diseases with TCM.

Objective To investigate the value of early maternal serological indicators in predic-ting the delivery of full-term small-for-gestational-age(SGA)infants.Methods The clinical data of pregnant women who delivered at Beijing Tongzhou District Maternal and Child Health Hospital from August 2023 to August 2024 were analyzed.A total of 180 pregnant women who delivered full-term SGA infants were included in case group,and 180 pregnant women who delivered full-term appropri-ate-for-gestational-age(AGA)infants during the same period were included in control group.The levels of serum pregnancy-associated plasma protein A(PAPP-A),placenta growth factor(PLGF),and soluble fms-like tyrosine kinase-1(sFlt-1)in the first trimester(11 to 13 weeks+6 days of ges-tation)of the two groups were compared.Receiver operating characteristic(ROC)curves were used to analyze the predictive value of early maternal serological indicators for the delivery of full-term SGA infants.Results The levels of serum PAPP-A and PLGF in the first trimester of the case group were lower than those in the control group,while the level of sFlt-1 was higher(P＜0.05).The area un-der the ROC curve(AUC)for the combined detection of serum PAPP-A,PLGF,and sFlt-1 levels in the first trimester in predicting the delivery of full-term SGA infants was 0.823,which was higher than the AUCs for detection of each indicator(0.738,0.720,0.724)(P＜0.05).Conclusion The detection of early maternal PAPP-A,PLGF,and sFlt-1 levels can reflect the fetal growth status in utero.The combined detection of these three indicators has a higher predictive value for the delivery of full-term SGA infants by pregnant women,which is helpful for clinicians to take intervention measures in advance.

Objective:To investigate the clinical characteristics and prognosis of patients with left ventricular assist device (LVAD) implantation during the perioperative period.Methods:This retrospective study included 14 patients with end-stage heart failure who underwent LVAD implantation in the department of intensive care medicine of Nanjing Hospital Affiliated to Nanjing Medical University from February 2022 to March 2023, including 12 males and 2 females patients, the mean age was (57.6±9.8)years old. All patients were implanted with Corheart 6 implantable left ventricular assist system, did not use other mechanical assisted circulatory devices. The clinical data of enrolled patients were collected, and the clinical characteristics and prognosis during ICU treatment were analyzed.Results:Dilated cardiomyopathy (DCM) was the most common primary cause of heart failure. The results of transthoracic echocardiography showed that the left ventricular ejection fraction (0.297±0.074 vs. 0.238±0.064, P=0.031) of patients was significantly increased, while the left ventricular end diastolic diameter[69.0(65.8, 74.3)mm vs. 76.5(72.8, 83.0)mm, P=0.003]and systolic end systolic diameter[61.5(53.7, 65.3)mm vs. 68.3(63.8, 71.9)mm, P=0.005]were significantly decreased post LVAD implantation as compared to before LVAD implantation. Within one week after implantation, there was no significant difference in LVAD rotational speed, flow rate, and pulsation index ( P>0.05). During ICU treatment, dobutamine (13 cases) was the most commonly used vasoactive agent. 9 patients used phosphodiesterase Ⅲ inhibitors for perioperative pulmonary hypertension. Targeted management of volume and pressure indicators was conducted for enrolled patients to prevent postoperative right heart failure and to reduce right heart burden. Within 72 hours after LVAD implantation, the average pulmonary artery pressure of patients was 24 (22, 26) mmHg to 26 (21, 28)mmHg (1 mmHg=0.133 kPa), while the fluid balance was(-581±778)ml to(-1 209±1 134)ml. All enrolled patients survived to 28 days after LVAD implantation. The length of stay in the ICU was (8.0±1.8) days and the total length of hospital stay was 33 (29, 41)days, while the time of mechanical ventilation was 8 (5, 28)h. Conclusion:LVAD implantation can help improve left ventricular systolic function, prolong survival time so as to serve as an important means of terminal treatment or bridging therapy for heart transplantation of patients with end-stage heart failure. To strengthen the perioperative hemodynamic regulation and maintain the cardiac function of patients with LVAD implantation is the important purposes of ICU postoperative management.

Objective To explore left ventricular longitudinal systolic function changes during perioperative period of coronary artery bypass graft(CABG).Methods Totally 41 patients with confirmed coronary artery disease(CAD)who underwent CABG were prospectively enrolled.The preoperative left ventricular global longitudinal strain(GLS),as well as GLS on the day of CABG,on the 3rd and 7th day postoperation were measured.According to preoperative left ventricular GLS,the patients were divided into 3 groups,i.e.normal group(group A,GLS≤-18.1％,n=6),mildly decreased group(group B,-18.1％＜GLS≤-14.0％,n=22)and severely decreased group(group C,GLS＞-14.0％,n=13).Repeated measures analysis of variance,generalized estimating equation and multiple comparisons were used to analyze left ventricular systolic function in different perioperative time points.Results No significant difference of GLS was found among different time points during perioperative period of CABG in group A and C(all adjusted P＞0.05).In group B,GLS on postoperative days were lower than that before CABG(all adjusted P＜0.001),and the lowest value was observed on the day of CABG postoperatively,while no significant difference of GLS was found between the 3rd and 7th day postoperation(adjusted P=1.00).Compared with those before CABG,the longitudinal strain(LS)of basal segment on the day of CABG postoperatively and 3rd day postoperation,of middle segment and apical segment at all postoperative time points were lower(all adjusted P＜0.05),while of the apical segment on the day of CABG postoperatively decreased most obviously.No significant difference of LS of each ventricular segment was found between the 3rd nor the 7th day postoperation(all adjusted P＞0.05).Conclusion GLS decreased significantly on the day of CABG postoperatively but partially recovered within the following week in CAD patients with mildly decreased preoperative GLS.CABG had the most pronounced effect on LS of apical segment in left ventricle.

Objective:To explore the clinical manifestation, treatments, and outcomes of immune checkpoint inhibitor (ICI)-induced immune-mediated liver injury (IMLI).Methods:The patients with ICI- related IMLI and hospitalized in the Department of Oncology, the Affiliated Hospital of Qingdao University from January 2018 to November 2022 were collected. The basic information, tumor treatments, clinical manifestation, treatments and outcomes of the patients with IMLI were retrospectively analyzed.Results:A total of 29 patients were included in the study, including 17 males (58.6%) and 12 females (41.4%), with a median age of 65 years. The median treatment cycle from the use of ICI to the occurrence of liver injury was 3 cycles, and the median time was 78 days. In patients with IMLI, 48.3% (14/29) had no obvious symptoms and 51.7% (15/29) had symptoms such as decreased appetite, nausea, abdominal distension, fatigue, fever and jaundice; 44.8% (13/29) were accompanied by other immune-related adverse events. The clinical classification of IMLI was hepatocellular type in 18 patients (62.1%), cholestasis type in 4 patients (13.8%), and mixed type in 7 patients (24.1%). According to the Common Terminology Criteria for Adverse Events (CTCAE) classification, severe liver injury (≥ grade 3) accounted for 86.2% (25/29), while according to the Chinese Diagnosis and Treatment Guideline on Drug-Induced Liver Injury (DILI guidelines) classification, severe liver injury (≥ grade 2) accounted for 34.5% (10/29). All 29 patients discontinued the treatment of ICIs after occurrence of IMLI, and 28 patients were treated with glucocorticoids, 7 of which were combined with mycophenolate mofetil and/or human immunoglobulin and artificial liver; 22 patients (75.9%) were improved. In the other 7 patients that did not recover, 4 discharged automatically, 2 died, and 1 could not be judged. ICI was rechallenged in 3 patients after liver function improvement, and IMLI did not recur. Conclusions:The IMLIs often occur 2 to 3 months after the start of ICI treatment, the most common clinical type is hepatocyte type, and the severity of clinical symptoms in patients vary from mild to severe. After discontinuing ICIs and receiving glucocorticoid treatments, most patients may have a good prognosis.
