Protection of inactivated vaccine against SARS-CoV-2 infections in patients with comorbidities: a prospective

《医学前沿（英文）》   页码 867-877 doi: 10.1007/s11684-023-0995-9

摘要： Protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection of inactivated vaccines is not well characterized in people with comorbidities, who are at high risk of severe infection. We compared the risk of SARS-CoV-2 infection after complete vaccination with Sinopharm/BBIBP in people with comorbidities (e.g., autoimmune diseases, cardiovascular disease, chronic lung disease, and diabetes) with healthy individuals using a Cox-proportional hazard model. In July–September 2021, a total of 10 548 people (comorbidities, 2143; healthy, 8405) receiving the complete primary series of vaccination with Sinopharm/BBIBP in Bangkok, Thailand were prospectively followed for SARS-CoV-2 infection through text messaging and telephone interviewing for 6 months. A total of 295 infections from 284 participants were found. HRs (95% CI) of individuals with any comorbidities did not increase (unadjusted, 1.02 (0.77–1.36), P = 0.89; adjusted, 1.04 (0.78–1.38), P = 0.81). HRs significantly increased in the subgroup of autoimmune diseases (unadjusted, 2.64 (1.09–6.38), P = 0.032; adjusted, 4.45 (1.83–10.83), P = 0.001) but not in cardiovascular disease, chronic lung disease, or diabetes. The protection against SARS-CoV-2 infection of the Sinopharm vaccine was similar in participants with any comorbidities vs. healthy individuals. However, the protection appeared lower in the subgroup of autoimmune diseases, which may reflect suboptimal immune responses among these people.

Reliability of foam posturography in assessment of postural balance in the patients with vertigo

LIU Bo, KONG Weijia

《医学前沿（英文）》 2008年 第2卷 第4期   页码 361-365 doi: 10.1007/s11684-008-0069-z

摘要： The postural balance is a important aspect of assessment in vestibular rehabilitation therapy. As the computerized dynamic posturography, the foam posturography performed by using foam in posturography is a useful measurement tool for postural balance. Then, the reliability of foam posturography is critical in clinic. To our knowledge, there is no report about the test-retest reliability of foam posturography in the patients with vertigo in China. The foam posturography was taken on the patients with vertigo in stable state and repeated in 3 to 5 days. In the two assessments of test and retest, all subjects stood under 4 sensory conditions, such as firm surface with eyes open (T1), firm surface with eyes closed (T2), foam surface with eyes open (T3) and foam surface with eyes closed (T4) for 30 seconds respectively. The average sway velocity (SV) of center of pressure (COP) under feet of upright standing was recorded as research parameter. The results of patients with vertigo were compared with those of normal subjects. It demonstrated that all normal subjects did not fall in the two assessments. There were 10 of 34 patients with vertigo at least fell one time during the two assessments, and the SVs of these subjects did not taken the analysis of test-retest reliability. The results showed that: (1) The interclass correlation coefficients (ICC) of all 49 subjects including normal subjects and patients without falling were 0.887–0.973 according to the T1–T4 between two assessment. (2) The SVs between the normal subjects and patients were significantly different in the T2 ( = 2.018, = 0.049) and T4 ( = 3.905, < 0.001) in the first assessment and in the T4 ( = 3.715, = 0.001) in the second. And (3) the cases of falling between two assessments were not significant different ( = 0.073, = 0.787) in the patients with vertigo. It is concluded from this study that the foam posturography has high test-retest reliability to assess the postural balance in the patients with vertigo in stable state, indicating the foam posturography can be used as the valid means to assess the improvement of postural balance for patients with vertigo in the vestibular rehabilitation therapy.

《医学前沿（英文）》 2016年 第10卷 第4期   页码 437-443 doi: 10.1007/s11684-016-0472-9

摘要：

A phase II study (A2202) was performed to evaluate the efficacy and safety of JAK inhibitor ruxolitinib in 63 Chinese MF patients. Ruxolitinib was given twice a day (bid) at a starting dose of 15 mg (n=25) or 20 mg (n=38) based on a baseline platelet count. About 94.7% of the patients achieved a reduction in spleen size, 27.0% of which exhibited significant reduction (≥35%) at week 24. Significant improvement in debilitating constitutional symptoms, as assessed by MFSAF v2.0, was observed in patients treated with ruxolitinib. Ruxolitinib treatment was generally well tolerated by Chinese patients. Although the treatment was associated with an increase in certain adverse events (AEs) that were established as identified risks (anemia and thrombocytopenia), these AEs were considered manageable in this clinical setting. Ruxolitinib provided substantial reductions in splenomegaly and improvements in symptoms, and was well-tolerated by Chinese patients with MF.

Predictive values of plasma TNFα and IL-8 for intracranial hemorrhage in patients with acute promyelocytic

《医学前沿（英文）》 2022年 第16卷 第6期   页码 909-918 doi: 10.1007/s11684-021-0890-1

摘要： In patients with acute promyelocytic leukemia (APL), intracranial hemorrhage (ICH), if not identified promptly, could be fatal. It is the leading cause of failure of induction and early death. Thus, biomarkers that could promptly predict severe complications are critical. Here, cytokine differences between patients with APL with and without ICH were investigated to develop predictive models for this complication. The initial cytokine profiling using plasma samples from 39 patients and 18 healthy donors found a series of cytokines that were remarkedly different between patients with APL and healthy controls. The APL patients were subsequently divided into high and low white blood cell count groups. Results showed that tumor necrosis factor α and interleukin 8 (IL-8) were vital in distinguishing patients with APL who did or did not develop ICH. In addition, verification in 81 patients with APL demonstrated that the two cytokines were positively correlated with the cumulative incidence of ICH. Finally, in-vitro and in-vivo experimental evidence were provided to show that IL-8 influenced the migration of APL-derived NB4 cells and impaired the blood–brain barrier in PML/RARα positive blast-transplanted FVB/NJ mice. These assessments may facilitate the early warning of ICH and reduce future mortality levels in APL.

Effects of combined procedure and devascularization alone on hyperdynamics of the portal venous system in patients

HUA Rong, SUN Yongwei, WU Zhiyong

《医学前沿（英文）》 2008年 第2卷 第3期   页码 244-247 doi: 10.1007/s11684-008-0046-6

摘要： Shunts and devascularizations have totally different effects on the hemodynamics of the portal venous system. The actual results of pericardial devascularization (PCDV) alone and conventional splenorenal shunt combined with pericardial devascularization (combined procedure, CP) should be determined by more clinical observations. This study aimed to evaluate effects on hemodynamics in the portal venous system after CP and PCDV only. In 20 patients who received CP and 18 who received PCDV, hemodynamic parameters of the portal venous system were studied by magnetic resonance angiography 1 week before and 2 weeks after operation. Free portal pressure (FPP) was continuously detected by a transducer during the operations. Compared to the preoperative data, a decreased flow in the portal vein (PVF) [(563.12 ± 206.42) mL/min (1080.63 ± 352.85) mL/min, < 0.05], a decreased portal vein diameter (PVD) [(1.20 ± 0.11) cm (1.30 ± 0.16) cm, < 0.01], a decreased FPP [(21.50 ± 2.67) mmHg (29.88 ± 2.30) mmHg, < 0.01] and an increased flow in the superior mesenteric vein (SMVF) [(1105.45 ± 309.03) mL/min (569.13 ± 178.46) mL/min, < 0.05] were found in the CP group after operation; a decreased PVD [(1.27 ± 0.16) cm (1.40 ± 0.23) cm, < 0.05], a decreased PVF [(684.60 ± 165.73) mL/min (1175.64 ± 415.09) mL/min, < 0.05], a decreased FPP [(24.40 ± 3.78) mmHg (28.80 ± 3.56) mmHg, < 0.05] and an increased SMVF [(697.91 ± 121.83) mL/min (521.30 ± 115.82) mL/min, < 0.05] were observed in the PCDV group. After operation, PVF in the CP group [(563.12 ± 206.42) mL/min (684.60 ± 165.73) mL/min, > 0.05] had no significant decrease, while FPP [(21.50 ± 2.67) mmHg (24.40 ± 3.78) mmHg, < 0.01] had a significant decrease as compared with that in the PCDV group. PVF and FPP could be decreased by both surgical procedures, but the effect of decreasing FPP was much better in the combined procedure than in PCDV alone. Further, there was no significant difference in PVF between the two groups. It is suggested that the combined surgical procedure could integrate the advantages of shunting with those of devascularization, as well as maintaining the normal anatomic structure of hepatic portal system, thus it should be one of the best choices for patients with portal hypertension when surgical interventions are considered.

The clinical impact of tricuspid regurgitation in patients with a biatrial orthotopic heart transplant

《医学前沿（英文）》 2023年 第17卷 第3期   页码 527-533 doi: 10.1007/s11684-022-0967-5

摘要： In this study, we aim to elucidate the clinical impact and long-term course of tricuspid regurgitation (TR), taking into account its dynamic nature, after biatrial orthotopic heart transplant (OHT). All consecutive adult patients undergoing biatrial OHT (1984−2017) with an available follow-up echocardiogram were included. Mixed-models were used to model the evolution of TR. The mixed-model was inserted into a Cox model in order to address the association of the dynamic TR with mortality. In total, 572 patients were included (median age: 50 years, males: 74.9%). Approximately 32% of patients had moderate-to-severe TR immediately after surgery. However, this declined to 11% on 5 years and 9% on 10 years after surgery, adjusted for survival bias. Pre-implant mechanical support was associated with less TR during follow-up, whereas concurrent LV dysfunction was significantly associated with more TR during follow-up. Survival at 1, 5, 10, 20 years was 97% ± 1%, 88% ± 1%, 66% ± 2% and 23% ± 2%, respectively. The presence of moderate-to-severe TR during follow-up was associated with higher mortality (HR: 1.07, 95% CI (1.02–1.12), p = 0.006). The course of TR was positively correlated with the course of creatinine (R = 0.45). TR during follow-up is significantly associated with higher mortality and worse renal function. Nevertheless, probability of TR is the highest immediately after OHT and decreases thereafter. Therefore, it may be reasonable to refrain from surgical intervention for TR during earlier phase after OHT.

Hybrid deep learning model for risk prediction of fracture in patients with diabetes and osteoporosis

《医学前沿（英文）》 2022年 第16卷 第3期   页码 496-506 doi: 10.1007/s11684-021-0828-7

摘要： The fracture risk of patients with diabetes is higher than those of patients without diabetes due to hyperglycemia, usage of diabetes drugs, changes in insulin levels, and excretion, and this risk begins as early as adolescence. Many factors including demographic data (such as age, height, weight, and gender), medical history (such as smoking, drinking, and menopause), and examination (such as bone mineral density, blood routine, and urine routine) may be related to bone metabolism in patients with diabetes. However, most of the existing methods are qualitative assessments and do not consider the interactions of the physiological factors of humans. In addition, the fracture risk of patients with diabetes and osteoporosis has not been further studied previously. In this paper, a hybrid model combining XGBoost with deep neural network is used to predict the fracture risk of patients with diabetes and osteoporosis, and investigate the effect of patients’ physiological factors on fracture risk. A total of 147 raw input features are considered in our model. The presented model is compared with several benchmarks based on various metrics to prove its effectiveness. Moreover, the top 18 influencing factors of fracture risks of patients with diabetes are determined.

《医学前沿（英文）》 2008年 第2卷 第1期   页码 15-18 doi: 10.1007/s11684-008-0004-3

摘要： It is challenging to undo early percutaneous intervention (PCI) in the elderly with acute coronary syndrome (ACS). Fifteen patients older than 65 years with ACS within 24 hours of the event were admitted from April 4, 2004 to December 12, 2005. All the patients had early percutaneous coronary intervention and were followed up for 6–12 months by telephone or in the out-patient department. Nine of the 15 patients exhibited acute myocardial infarction (AMI). Six exhibited unstable angina (UA). All the patients had early PCI. The average door-to-balloon time was 78 minutes (40–110 minutes). The average PCI time was 99 minutes (68–120 minutes). Nineteen of 36 lesions in the fifteen angioplasty patients were treated and 20 stents were implanted in total. All the procedures were considered successful. Neither deaths nor recurrent angina occurred in the 6–12 months of follow-up. It was shown that early PCI might be an effective and safe method to treat elderly patients with ACS.

《医学前沿（英文）》 2008年 第2卷 第2期   页码 139-142 doi: 10.1007/s11684-008-0026-x

摘要： There is no conclusive answer to the question whether excising gall bladder is helpful to the patient with hepatic cancer. The survival rate of patients with hepatic cancer for more than two years has been increased, and the incidence of complications of cholecystitis and gall stone are relatively higher among these patients, which may seriously complicate treatment of advanced hepatic cancer and decrease quality of life. The researchers conducted a prospective clinical investigation from 2002 to 2006 to assess the clinical significance of preventive cholecystectomy in patients with hepatic cancer. One hundred and eighteen cases of postoperative patients with hepatic cancer, who survived for more than two years, were followed up. Based on whether cholecystectomy was performed, the patients were divided into two groups including 48 cases with cholecystectomy and 70 cases with cholecyst reserved. The two-year morbidity of gall stone and morbidity of pain in the right upper abdomen of cholecyst reservation group were 54.29% and 68.57%, respectively, obviously higher than 0.00% and 20.83% of cholecystectomy group. Mainly for those treated with transcatheter arterial chemo-embolization, the morbidity of gall stone was 86.67% ( < 0.01). Therefore, preventive cholecystectomy is strongly recommended during hepatectomy to decrease the incidence of chronic cholecystitis and gall stone, especially for those whose chemotherapy and embolization will be carried out through hepatic artery and portal vein.

摘要：

Obstructive sleep apnea syndrome (OSAS) increases the risk of post-surgery complications. This study uses Berlin Questionnaire (BQ) to identify Chinese adult surgical patients who are at a high risk of OSAS and to determine if the BQ could be used to detect potential high risk of adverse respiratory events in the post anesthesia care unit (PACU). Results indicated that only 11.4% of the patients were considered at a high risk of OSAS. Age and body mass index are the key factors for the risk of OSAS prevalence in China and also gender specific. Furthermore, the incidence of adverse respiratory events in the PACU was higher in patients with high risk of OSAS than others (6.8% vs. 0.9%, <0.001). They also stayed longer than others in the PACU (95±28 min vs. 62±19 min, <0.001). Age, high risk for OSAS, and smoking were independent risk factors for the occurrence of adverse respiratory events in the PACU. The BQ may be adopted as a screening tool for anesthesiologists in China to identify patients who are at high risk of OSAS and determine the potential risk of developing postoperative respiratory complications in the PACU.

Effectiveness of quality of care for patients with type 2 diabetes in China: findings from the Shanghai

《医学前沿（英文）》 2022年 第16卷 第1期   页码 126-138 doi: 10.1007/s11684-021-0897-7

摘要： This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43±8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95±5.53 (SD) years. The percentage of patients who achieved the target level for HbA1c (<7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP)<130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c)<2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (<140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

摘要：

Peritoneal dialysis (PD) is an established form of renal replacement therapy. Long-term PD leads to morphologic and functional changes to the peritoneal membrane (PM), which is defined as peritoneal fibrosis, a known cause of loss of peritoneal ultrafiltration capacity. Inflammation and angiogenesis are key events during the pathogenesis of peritoneal fibrosis. This review discusses the pathophysiology of peritoneal fibrosis and recent research progress on key fibrogenic molecular mechanisms in peritoneal inflammation and angiogenesis, including Toll-like receptor ligand-mediated, NOD-like receptor protein 3/interleukin-1β, vascular endothelial growth factor, and angiopoietin-2/Tie2 signaling pathways. Furthermore, novel strategies targeting peritoneal inflammation and angiogenesis to preserve the PM are discussed in depth.
