Higher Cumulative Survival Rate Research Articles

A Multicenter Cohort Study on 301 Tissue-Level Implants: Cumulative Implant Survival Rate and Marginal Bone Level Change up to 4.5 Years.

To retrospectively determine the cumulative survival rate (CSR) and marginal bone level change (ΔMBL) around novel hybrid design tissue-level (TL) dental implants that support multiple-screw-retained restorations. Implant CSRs were analyzed at the implant and patient level using Kaplan-Meier estimates. ΔMBL was measured by comparing the periapical loading and follow-up visit radiographs using an improved standardized digital methodology based on image gray levels. ΔMBL outcomes were subject to linear mixed regression to identify potential risk factors. A total of 301 TL implants in 69 patients with an average age of 62.6 ± 11.7 years (range: 36 to 87 years) at the time of implant placement were considered for the analysis. All 301 implants were successfully restored and loaded. The 54-month CSRs at the implant and patient levels were 98.9% (95% CI: 96.7 to 99.6) and 95.3% (95% CI: 86.1 to 98.5), respectively. ΔMBL after a mean follow-up of 22 ± 10.7 months after loading was 0.00 ± 0.57 mm. None of the implant sites showed marginal bone loss exceeding 1.5 mm. Multivariate regression analysis revealed a significant association between ΔMBL and the loading protocol (P = .027) but not between ΔMBL and age or transgingival height. The high CSRs and stable peri-implant marginal bone levels support the use of recent TL implants, which have a hybrid design inherited from the bone-level implant-abutment connection, as a suitable treatment option for restoring partially or fully edentulous patients with a good mid-term prognosis. These results should be complemented by further prospective studies in a real-world multicenter private practice setup that represents the daily realities of implant treatment.

Association of Systemic Immune-Inflammation Index and Systemic Inflammation Response Index with Diabetic Kidney Disease in Patients with Type 2 Diabetes Mellitus.

To evaluate the association of the systemic immune-inflammatory index (SII) and systemic inflammatory response index (SIRI) with the clinical and pathological features and progression of diabetic kidney disease (DKD). We analyzed 303 patients with type 2 diabetes mellitus (T2DM), classifying them into distinct groups: T2DM, early DKD (EDKD), and clinical DKD (Cli-DKD). Variations in SII and SIRI levels across these groups and their association with renal function were assessed. Logistic regression analysis was used to identify independent risk factors for DKD. Additionally, in 43 patients with biopsy-confirmed DKD, we analyzed the relationship between SII, SIRI, and pathological changes. Kaplan-Meier survival analysis and the Cox proportional hazards model were used to assess the influence of SII and SIRI levels on outcomes in patients with DKD. SII and SIRI were significantly higher in the Cli-DKD group than in the T2DM and EDKD groups, and were positively correlated with the urinary albumin-creatinine ratio and negatively correlated with estimated glomerular filtration rate. Notably, SIRI was identified as an independent risk factor for DKD development. Additionally, a lower SII score was associated with a higher cumulative survival rate. This study demonstrates an association between SII, SIRI, and renal function in patients with T2DM. A high SIRI was an independent risk factor for DKD, while an elevated SII was associated with an increased risk of kidney disease progression in biopsy-confirmed DKD cases. Our findings underscore the potential implications of utilizing SII and SIRI as cost-effective and readily available inflammatory indicators for monitoring DKD in primary care settings.

Relationship between initial red cell distribution width and ΔRDW and mortality in cardiac arrest patients.

There has been a lack of research examining the relationship between red cell distribution width (RDW) and the prognosis of cardiac arrest (CA) patients. The prognostic value of the changes in RDW during intensive care unit (ICU) hospitalization for CA patients has not been investigated. This study aims to investigate the correlation between RDW measures at ICU admission and RDW changes during ICU hospitalization and the prognosis of CA patients and then develop a nomogram that predicts the risk of mortality of these patients. A retrospective cohort study is used to collect clinical characteristics of CA patients (>18years) that are on their first admission to ICU with RDW data measured from the Medical Information Mart for Intensive Care IV Version 2.0 database. Patients are randomly divided into a development cohort (75%) and a validation cohort (25%). The primary outcome is 30 and 360day all-cause mortality. ΔRDW is defined as the RDW on ICU discharge minus RDW on ICU admission. A multivariate Cox regression model is applied to test whether the RDW represents an independent risk factor that affects the all-cause mortality of these patients. Meanwhile, the dose-response relationship between the RDW and the mortality is described by restricted cubic spine (RCS). A prediction model is constructed using a nomogram, which is then assessed using receiver operating characteristic curves, calibration curves, and decision curve analysis (DCA). A total of 1278 adult CA patients are included in this study. We found that non-survivors have a higher level of RDW and ΔRDW compared with survivors, and the mortality rate is higher in the high RDW group than in the normal RDW group. The Kaplan-Meier survival curve indicates that patients in the normal RDW group had a higher cumulative survival rate at 30 and 360days than those in the high RDW group (log-rank test, χ2 =36.710, χ2 =54.960, both P values <0.05). The multivariate Cox regression analysis shows that elevated RDW at ICU admission (>15.50%) is an independent predictor of 30 [hazard ratio=1.451, 95% confidence interval (CI)=1.181-1.782, P<0.001] and 360day (hazard ratio=1.393, 95% CI=1.160-1.671, P<0.001) all-cause mortality among CA patients, and an increase in RDW during ICU hospitalization (ΔRDW≥0.4%) can serve as an independent predictor of mortality among these patients. A non-linear relationship between the RDW measured at ICU admission and the increased risk of mortality rate of these patients is shown by the RCS. This study established and validated a nomogram based on six variables, anion gap, first-day Sequential Organ Failure Assessment score, cerebrovascular disease, malignant tumour, norepinephrine use, and RDW, to predict mortality risk in CA patients. The consistency indices of 30 and 360day mortality of CA patients in the validation cohort are 0.721 and 0.725, respectively. The nomogram proved to be well calibrated in the validation cohort. DCA curves indicated that the nomogram provided a higher net benefit over a wide, reasonable range of threshold probabilities for predicting mortality in CA patients and could be adapted for clinical decision-making. Elevated RDW levels on ICU admission and rising RDW during ICU hospitalization are powerful predictors of all-cause mortality for CA patients at 30 and 360days, and they can be used as potential clinical biomarkers to predict the bad prognosis of these patients. The newly developed nomogram, which includes RDW, demonstrates high efficacy in predicting the mortality of CA patients.

Policy-Driven Post-Acute Care Program Lowers Mortality Rate and Medical Expenditures After Hospitalization for Acute Heart Failure: A Nationwide Propensity Score-Matched Study.

The beneficial effects of multidisciplinary disease management programs have been demonstrated. The present study investigated the effects of a policy-driven, health insurance-reimbursed, heart failure (HF) post-acute care (PAC) program on mortality, health care service utilization, and readmission expenses for patients following hospitalization for HF. This was a retrospective propensity score-matched cohort study using the Taiwan National Health Insurance Research Database. In total, 4346 patients (2173 receiving HF-PAC and 2173 controls) with left ventricular ejection fraction of ≤40% who were discharged following hospitalization for HF were included for analysis. All patients were followed up after discharge for all-cause mortality, emergency visits within 30days, and length of stay and medical expenses for readmission within 180days after discharge. After propensity score matching, baseline characteristics of the HF-PAC and control groups were similar. During a mean follow-up period of 1.59 ± 0.92years, according to the Cox multivariable analysis, HF-PAC reduced mortality by 48% compared with the control group, independent of traditional risk factors (hazard ratio= 0.520, 95% CI= 0.452-0.597, P < .001). Kaplan-Meier curves revealed that HF-PAC was associated with a higher cumulative survival rate (log-rank= 96.43, P < .001). HF-PAC also decreased the frequency of emergency visits after discharge by 23% in the 30days post discharge and decreased length of stay and medical expenses related to readmission by 61% and 63%, respectively, in the 180days post discharge (all P < .001). HF-PAC reduces short-term all-cause emergency visits, length of stay, and medical expenses for all-cause readmission and all-cause mortality in patients discharged following hospitalization for HF. Our findings suggest that PAC should include care continuity, optimal adaptation of transitional care components, and HF cardiologist engagement with multidisciplinary coordination.

Vestibuloplasty and its impact on the long-term survival and success of dental implants in irradiated and non-irradiated patients after head and neck tumor therapy: a retrospective study

ObjectivesThis study aimed to evaluate the influence of vestibuloplasty on the clinical success and survival of dental implants in head and neck tumor patients.Materials and methodsA retrospective single-center study was conducted. All patients received surgical therapy of a tumor in the head or neck and underwent surgical therapy and, if necessary, radiotherapy/radiochemotherapy. Patients with compromised soft tissue conditions received vestibuloplasty using a split thickness skin graft and an implant-retained splint. Implant survival and success and the influence of vestibuloplasty, gender, radiotherapy, and localizations were evaluated.ResultsA total of 247 dental implants in 49 patients (18 women and 31 men; mean age of 63.6 years) were evaluated. During the observation period, 6 implants were lost. The cumulative survival rate was 99.1% after 1 year and 3 years and 93.1% after 5 years for patients without vestibuloplasty, compared to a survival and success rate of 100% after 5 years in patients with vestibuloplasty. Additionally, patients with vestibuloplasty showed significantly lower peri-implant bone resorption rates after 5 years (mesial: p = 0.003; distal: p = 0.001).ConclusionThis study demonstrates a high cumulative survival and success rate of dental implants after 5 years in head and neck tumor patients, irrespective of irradiation. Patients with vestibuloplasty showed a significantly higher rate of implant survival and significantly lower peri-implant bone resorption after 5 years.Clinical relevanceVestibuloplasty should always be considered and applied if required by the anatomical situations to achieve high implant survival/success rates in head and neck tumor patients.

#3430 MORTALITY AND RISK FACTORS IN VERY ELDERLY PATIENTS WHO START HAEMODIALYSIS: KOREAN RENAL DATA SYSTEM (KORDS), 2016-2020

Abstract Background and Aims The number of elderly patients with end-stage renal disease (ESRD) is increasing worldwide. However, decision-making about elderly patients with ESRD remains complex because of the lack of studies, especially in very elderly patients (≥75 years). We examined the characteristics of very elderly patients starting haemodialysis (HD) and the associated mortality and prognostic factors. Method Data were analysed retrospectively using a nationwide cohort registry, the Korean Renal Data System. Patients who started HD between January 2016 and December 2020 were included and divided into three groups according to age at HD initiation (&amp;lt;65, 65–74, and ≥75 years). The primary outcome was all-cause mortality during the study period. Risk factors for mortality were analysed using Cox proportional hazard models. Results In total, 22,024 incident patients were included with 10,006, 5,668, and 6,350 in each group (&amp;lt;65, 65–74, and ≥75 years, respectively). Among the very elderly group, women had a higher cumulative survival rate than men (91.2% vs. 90.3% at 1 year and 56.4% vs. 51.9% at 3 years, respectively) (Figure 1a). The survival rate was lower in patients with vascular access via a catheter than in those with an arteriovenous fistula or graft (72.0% vs. 95.1% at 1 year and 23.8% vs. 60.7% at 3 years, respectively) (Figure 1b). Very elderly patients with more comorbid diseases had a significantly lower survival rate that those with fewer comorbidities (log-rank: p &amp;lt; 0.001) (Figure 2). Conclusion Preparation of an arteriovenous fistula or graft when starting HD should be considered in very elderly patients with fewer comorbid diseases.

DnaJC16, the molecular chaperone, is implicated in hemocyte apoptosis and facilitates of WSSV infection in shrimp.

Chaperone proteins, including heat shock proteins (HSPs) and DnaJ proteins, are highly conserved and well known for their quick responses to environmental stresses and pathogen infections, especially viruses. However, how DnaJ, an HSP family member, in Penaeus vannamei responds to viral invasion has not been reported. In this research, the novel DnaJ homolog subfamily C member 16-like, or DnaJC16, was characterized in P. vannamei. It contains the DnaJ and thioredoxin domains. Phylogenetic tree analysis demonstrated the conservation of DnaJC16 among penaeid shrimp, where PvDnaJC16 was found to be closely related to DnaJC16 from Fenneropenaeus chinensis and Marsupenaeus japonicus. The transcripts of PvDnaJC16 were expressed in all the tissues tested, and the highest expression was in the lymphoid organs. As hemocytes are major immune tissue, we found significant upregulation of PvDnaJC16 in shrimp hemocytes after white spot syndrome virus (WSSV) infection. Furthermore, the suppression of PvDnaJC16 expression by RNA interference in WSSV-infected shrimp showed a decrease in replication and WSSV copy number. Interestingly, a dramatically high cumulative survival rate following the WSSV challenge (over 60%) was observed in PvDnaJC16-silenced shrimp. Meanwhile, the total hemocyte number was significantly increased in PvDnaJC16 knockdown. In addition, the expression of caspase-3 was reduced, as was the caspase-3/7 activity in PvDnaJC16 silencing. Additionally, the percentage of late apoptotic hemocytes diminished after PvDnaJC16 reduction, whereas the percentage of hemocyte viability increased. Our data reflect the fact that the upregulation of PvDnaJC16 expression upon WSSV infection enhances hemocyte apoptosis, which can accelerate viral spreading in shrimp.

Mortality and Risk Factors in Very Elderly Patients Who Start Hemodialysis: Korean Renal Data System, 2016–2020

Introduction: The number of elderly patients with end-stage renal disease (ESRD) is increasing worldwide. However, decision-making about elderly patients with ESRD remains complex because of the lack of studies, especially in very elderly patients (≥75 years). We examined the characteristics of very elderly patients starting hemodialysis (HD) and the associated mortality and prognostic factors. Methods: Data were analyzed retrospectively using a nationwide cohort registry, the Korean Renal Data System. Patients who started HD between January 2016 and December 2020 were included and divided into three groups according to age at HD initiation (<65, 65–74, and ≥75 years). The primary outcome was all-cause mortality during the study period. Risk factors for mortality were analyzed using Cox proportional hazard models. Results: In total, 22,024 incident patients were included with 10,006, 5,668, and 6,350 in each group (<65, 65–74, and ≥75 years, respectively). Among the very elderly group, women had a higher cumulative survival rate than men. The survival rate was lower in patients with vascular access via a catheter than in those with an arteriovenous fistula or graft. Very elderly patients with more comorbid diseases had a significantly lower survival rate than those with fewer comorbidities. In the multivariate Cox models, old age, cancer presence, catheter use, low body mass index, low Kt/V, low albumin concentration, and capable status of partial self-care were associated with high risk of mortality. Conclusion: Preparation of an arteriovenous fistula or graft when starting HD should be considered in very elderly patients with fewer comorbid diseases.

Evaluation of dietary fermented tuna by-product meal as partial replacement for unprocessed tuna by-product meal in fishmeal-based diets for juvenile olive flounder Paralichthys olivaceus.

This study examined the effects of feeding fermented tuna by-product (FTBP) on the growth, non-specific immune response, liver and intestinal morphology, and disease resistance of olive flounder Paralichthys olivaceus. Olive flounders (n = 20; 2g) were randomly assigned into four dietary groups in triplicates. Fish were fed four test diets (50% crude protein; 10% crude lipid) for 10weeks in which unprocessed tuna by-product (TBP) meal was replaced (on a protein basis) with 0% (FTBP0 as the control diet), 15% (FTBP15), 30% (FTBP30), and 60% (FTBP60) of FTBP protein. Results showed that growth performance, blood parameters, and proximate composition were not influenced by FTBP inclusion. Non-specific immune parameters such as superoxide dismutase activity in the FTBP30 and FTBP60 groups were significantly higher than in the FTBP15 and the control groups, whereas lysozyme and myeloperoxidase activities were not different. Liver histopathology revealed normal architecture in groups fed FTBP0 and FTBP15 diets although mild alterations were noted in the FTBP30- and FTBP60-fed groups. Intestinal villi height and muscular thickness were not significantly altered with FTBP inclusion. Moreover, higher cumulative survival rate was observed in the FTBP60-fed group than fish fed with the other diets following the 13-day challenge with E. tarda. Together, these results demonstrate that fermented tuna by-product meal could be included at 60% in olive flounder diets.

Major clinical outcomes for optimization of zygomatic implants: a systematic review

Introduction: In the context of implantology, the rehabilitation of an atrophic maxilla is a challenge. In case of severe resorption, zygomatic implants (ZI) are indicated and loading of the implants is advised at the end of the surgery. Also, quad zygomatic implants have been used as a treatment option for patients with severely resorbed maxilla. Objective: The present study aimed to carry out a systematic review of the main approaches and clinical outcomes of zygomatic implantation in the last ten years. Methods: The present study followed the PRISMA rules and a model of literary review presenting and publishing case series, prospective, retrospective, randomized, double-blind, placebo-controlled trials in humans with a time of the last ten years were selected and analyzed. Results and Conclusion: Under the objective proposed in this study, it was concluded that the ZI has a high 12-year cumulative survival rate, with most failures occurring in the early stages of the postoperative period. Furthermore, the zygomatic bone is a viable site for zygomatic implants and the use of specialized implant planning software is an important tool to achieve predictable results for ZI. Preliminary data one year after loading suggest that immediately loaded ZIs were associated with fewer prosthetic failures, fewer implant failures, and shorter time required for functional loading.

Comparison of Coronary Artery Bypass Grafting and Drug-Eluting Stent Implantation in Patients With Chronic Kidney Disease: A Propensity Score Matching Study.

ObjectivesTo compare the long-term outcomes of coronary artery bypass grafting (CABG) vs. percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) for coronary artery disease (CAD) patients with chronic kidney disease (CKD).MethodsCoronary artery disease patients with decreased kidney function (estimated glomerular filtration rate <60 ml/min/1.73 m2) who underwent CABG (n = 533) or PCI with DES (n = 952) from 2013 to 2020 were enrolled at a single center. The baseline characteristics and clinical outcomes were compared between the CABG and PCI groups for each matched pair of patients with CKD. The primary endpoint was the occurrence of all-cause death. The secondary endpoints were major adverse cardiovascular events (MACCEs) such as death, myocardial infarction (MI), stroke, and repeat revascularization.ResultsA total of 1,485 patients underwent revascularization, such as 533 CABG and 952 patients with PCI. The median follow-up duration was 55.6 months (interquartile range 34.3–74.7 months). Multivariable Cox regression models were used for risk adjustment, and after propensity score matching (PSM), 399 patients were well matched in each group. The in-hospital mortality rate in the CABG group was higher than that in the PCI group, but the difference was not statistically significant (5.0 vs. 2.5%, p = 0.063). At the 1-year follow-up, CABG was associated with a lower survival rate than PCI (94.2 vs. 98.0%, hazard ratio [HR] of 3.72, 95% CI = 1.63–8.49, p < 0.01). At the end of the 5-year follow-up, the freedom from MI and the freedom from repeated revascularization were both better in the CABG group compared to the PCI group (89.1 vs. 81.7%, HR of 0.59, 95% CI = 0.38–0.92, p = 0.019; 86.9 vs. 73.8%, HR of 0.54, 95% CI = 0.36–0.81, p = 0.003, respectively). Furthermore, the freedom from MACCEs was also better in the patients of CABG compared with the patients of PCI (58.5 vs. 51.3%, HR of 0.71, 95% CI = 0.55–0.91, p = 0.030). CABG had a higher cumulative survival rate (68.4 vs. 66.0%) but without a statistically significant difference (HR of 0.92, 95% CI = 0.67–1.27, p = 0.602) compared with that of PCI.ConclusionsCompared to the use of PCI with a drug-eluting stent among patients with CKD, the use of CABG was associated with a lower MI rate, repeat revascularization rate, and lower number of MACCEs during the long-term follow-up. At a follow-up of 1 year, the number of MACCEs and other adverse events were comparable between the two cohorts, but CABG showed a lower survival rate than PCI.

Sarcopenia in Patients with Cirrhosis after Transjugular Intrahepatic Portosystemic Shunt Placement.

Background Sarcopenia is frequently found in patients with cirrhosis and is associated with liver dysfunction, cirrhosis-related complications, and poorer quality of life. Purpose To evaluate changes in skeletal muscle and fat mass at CT and to evaluate the relationship of sarcopenia to mortality in patients with cirrhosis after transjugular intrahepatic portosystemic shunt (TIPS) placement. Materials and Methods Patients who underwent TIPS between August 2016 and May 2020 were included in this retrospective study. Skeletal muscle and fat mass were evaluated at CT at the L3 vertebra at baseline and at 2 months, 5 months, and 1 year after TIPS. Sarcopenia was defined as L3 skeletal muscle index (SMI) less than 50 cm2/m2 for men and less than 39 cm2/m2 for women. The primary end point was change in skeletal muscle and fat mass, and secondary end points included survival and the predictive factors for survival. Changes in skeletal muscle and fat mass over time were analyzed by generalized estimating equations. Results A total of 224 patients (159 men [113 with and 46 without sarcopenia] and 65 women [32 with and 33 without sarcopenia]) were included. In male patients with sarcopenia, the mean L3 SMI increased from 41.8 cm2/m2 (baseline) to 49.1 cm2/m2 (at 5-month follow-up; P < .001) and 49.6 cm2/m2 (at 1-year follow-up; P < .001) after TIPS. In female patients with sarcopenia, SMI increased from 33.7 cm2/m2 (at baseline) to 40.6 cm2/m2 (at 5-month follow-up; P < .001) and 42.0 cm2/m2 (at 1-year follow-up; P < .001) after TIPS. Sarcopenia (hazard ratio, 3.0; 95% CI: 1.2, 7.8) was identified as an independent risk factor for mortality after TIPS, and the patients who converted from sarcopenic to nonsarcopenic had higher cumulative survival rate than those who did not (96.4% vs 82.1%; log-rank P = .04). Conclusion In patients with sarcopenia, both skeletal muscle and fat mass increased after transjugular intrahepatic portosystemic shunt placement. The reversal of sarcopenia could reduce the risk of death. © RSNA, 2022 Online supplemental material is available for this article. See also the editorial by Lee in this issue.

A comparison of the physiological responses to heat stress of juvenile and adult starry flounder (Platichthys stellatus)

Water temperature is the most important factor in fish farming as changes in water temperature cause physiological stress in fish. There have been few studies on physiological responses to high temperatures, which vary with aging. This study investigated the responses of juvenile and adult Platichthys stellatus to heat stress. Plasma cortisol, glucose, lactate, and lysozyme levels, antioxidant enzyme activities, and expression of heat shock proteins 70 and 90 (HSP70 and HSP90) of P. stellatus were determined at water temperatures of 16, 20, 24, 28, and 30°C. As a result, it was confirmed that several plasma parameters of adult were significantly higher than that of juvenile under heat stress. Plasma cortisol and glucose levels of adult were increased than juvenile at 24 and 28°C. Plasma lactate level of adult were higher than that of juvenile at 28°C. Comparisons of survival and physiological changes showed that juveniles have better thermal tolerance, resulting in a higher cumulative survival rate. Moreover, the relationship between thermal tolerance and HSP gene expression revealed that expression of HSP70 and HSP90 was significantly upregulated at 28°C in both juvenile and adult fish, and HSP70 expression was significantly higher in juvenile fish than in adult fish. It is judged that the adult’s HSP70 activity was lower than juvenile, so the demand for plasma parameters for heat response was relatively high, whereas juvenile’s HSP70 activity increased at 24 and 28°C, indicating a relatively stable value of plasma parameters. These results indicate that the thermal tolerance of juvenile fish is greater than that of adult fish, based on the differences in plasma parameters and HSP expression. These findings improve our understanding of age-related changes in P. stellatus during thermal stress and may help guide the management of fish farms.

Abstract 9056: The Association Between Thoracic Injuries Due to Chest Compression and Short-Term Prognosis in Patients With Non-traumatic Out-of-Hospital Cardiac Arrest

Background: The current guidelines emphasize that high-quality chest compression is essential for improving the survival in out-of-hospital cardiac arrest (OHCA) patients. However, it may lead to thoracic injuries which is a potential factor of poor prognosis. Method: Between June 2017 to July 2019, we collected Utstein-style data on 384 consecutive adult patients with non-traumatic OHCA who were transferred to our hospital. Full-body CT scan was performed and thoracic injuries were defined as rib fracture, sternum fracture, hemorrhagic pleural effusion, pneumothorax, sternum posterior bleeding, mediastinal hematoma, or mediastinal emphysema. We identified the predictors for thoracic injuries and evaluated the relationship between thoracic injuries and prognosis. Results: Patients with thoracic injuries (Group-T) were 234 (76%). The duration of chest compression in Group-T was 43 min, which was significantly longer than that in patients without thoracic injuries (Group-N, 32 min, p&lt;0.001). ROC curve analysis identified a duration of chest compression of 35 minutes as the optimal cut off for predicting thoracic injuries (area under the curve 0.73). Multivariate analysis revealed that age (OR: 1.03, 95%CI: 1.01-1.05, p=0.005) and duration of chest compression (OR: 1.07, 95%CI: 1.04-1.09, p&lt;0.001) were independent predictors of thoracic injuries. The rate of obtaining return of spontaneous circulation (ROSC), 30-day survival and favorable neurologic outcome were larger in Group-N than Group-T. In patients with achieving ROSC, Kaplan-Meier curves showed a significantly higher cumulative survival rates in Group-N compared to that in Group-T during follow-up of 30 days (Log-rank test p=0.009). Conclusion: Age and duration of chest compression were independent predictors for thoracic injuries due to chest compression in non-traumatic OHCA patients. Moreover, the presence of thoracic injuries was associated with poor short-term prognosis.

Venous Thromboembolism in ICU Patients with Intracerebral Hemorrhage: Risk Factors and the Prognosis After Anticoagulation Therapy.

PurposeVenous thromboembolism (VTE) is a common complication of intracerebral hemorrhage (ICH) patients in intensive care unit (ICU), but anticoagulation therapy of ICH patients with VTE remains controversial. We aim to explore the risk factors and prognosis of anticoagulation therapy in ICH patients with VTE.Patients and MethodsMedical records of ICH patients were collected from the Medical Information Mart for Intensive Care III (MIMIC-III version 1.4) database. The risk factors and prognosis of anticoagulation therapy in ICH patients with VTE were assessed by multivariable logistic regression analysis and Kaplan–Meier survival analysis, respectively.ResultsA total of 848 ICH patients were included in our study, of whom 69 ICH patients with VTE were screened, including 58 patients with deep vein thrombosis (DVT), 12 patients with pulmonary embolism (PE), and 1 patient with DVT and PE. In the multivariable logistic regression analysis, malignancy (odds ratio (OR): 4.262, 95% confidence interval (CI): 2.263–8.027, P=0.000), pulmonary circulation disease (OR: 28.717, 95% CI: 9.566–86.208, P=0.000), coagulopathy (OR: 2.453, 95% CI: 1.098–5.483, P=0.029), age > 60 years old (OR: 2.138, 95% CI: 1.087–4.207, P=0.028) and hospitalization time > 16 days (OR: 2.548, 95% CI: 1.381–4.701, P=0.003) were independent risk factors for VTE in ICH patients. Kaplan–Meier survival analysis and log-rank test found that, compared to non-anticoagulation group, anticoagulation group had higher cumulative survival rates during hospitalization, 28-day, 3-month, 1-year, and 4-year after admission, respectively.ConclusionMalignancy, pulmonary circulation disease, coagulopathy, age >60 years old and hospitalization time >16 days were independent risk factors for VTE in ICH patients, and anticoagulation therapy for VTE in ICH patients may be safe and effective. These findings need to be verified by more high-quality and well-designed randomized controlled trials.

The association between variants in PLA2R and HLA-DQA1 and renal outcomes in patients with primary membranous nephropathy in Western China

BackgroundBoth Genome-wide associations and our previous study have shown that single nucleotide polymorphisms (SNPs) of M-type phospholipase A2 receptor (PLA2R) and human leukocyte antigen complex class II HLA-DQα-chain 1 (HLA-DQA1) gene were identified to be associated with primary membranous nephropathy (PMN). However, whether these SNPs affect clinical manifestation and renal outcome for PMN patients is poorly defined. Here, we evaluated whether there is an association between these SNPs and clinical manifestations and renal outcomes of PMN in a western Chinese cohort.MethodsSeven SNPs within PLA2R and one SNP in HLA-DQA1 were selected in our study. Clinical data from 314 patients with PMN were collected and the relationship between the genotype and phenotype was evaluated. A total of 186 patients had follow-up data. We assessed the treatment responses and renal outcomes between patients with these gene polymorphisms after a median follow-up of 18.6 months.ResultsEight SNPs were not associated with clinical manifestations of PMN patients (Pc < 0.05). rs3828323 T allele was marginally significantly associated with hypertension (P = 0.008, Pc = 0.064, OR = 1.821). After treatment for PMN, the SR group (including CR and PR) had lower serum creatinine level (68.4 ± 18.8 μmol/L vs. 122.8 ± 126.6 μmol/L, P < 0.001), urea (5.5 ± 1.9 mmol/L vs. 8.0 ± 4.0 mmol/L, P < 0.001), uric acid (358.5 ± 95.1 μmol/L vs. 392.8 ± 118.1 μmol/L, P = 0.037) and urinary protein (0.23 (0.76,1.05) g/d vs. 3.01 (2.06,7.95) g/d, P < 0.001), higher eGFR (100.0 ± 20.1 ml/min/1.73m2 vs. 77.1 ± 35.3 ml/min/1.73m2, P < 0.001) and albumin (41.1 ± 5.1 g/L vs.30.4 ± 8.2 g/L, P < 0.001). We also identified that PMN patients with CT/TT genotype for rs3828323 achieved higher cumulative survival rate than patients with CC genotype.ConclusionsRs3828323 may influence hypertension and renal outcome in patients with PMN. Further research is needed to explore the mechanism for this genotype-disease phenotype association.

Clinical effect evaluation of anodized and sandblasted, large-grit, acid-etched implants within 10 years: a meta-analysis

Objective: To systematically evaluate the clinical effect of anodized implants and sandblasted, large-grit, acid-etched (SLA) implants in the recent 10 years, so as to provide a reference for the selection and evaluation of implants. Methods: The data from Pubmed, Cochrane Library, Embase, CNKI, and Wanfang Data database from January 2010 to April 2020 were searched, to find clinical studies on anodized and SLA implants. According to the inclusion and exclusion criteria, literature was strictly screened, and data was extracted. Included studies were evaluated by using the methodological index for non-randomized studies (MINORS) and were analyzed by Stata14.0. The outcome of interest was cumulative survival rate (CSR) and marginal bone loss (MBL). Heterogeneity and publication bias among included literature was evaluated comprehensively. Results: A total of 22 articles, including 6 276 anodized implants, were collected for the analysis of anodized implants. Meta-analysis of proportions showed that anodized implants CSR were 98% (95%CI: 97%-98%, P<0.05) in total, at 5 years were 98% (95%CI: 98%-99%, P<0.05), and at 10 years were 97% (95%CI: 96%-98%, P<0.05). MBL change was 1.02 mm (95%CI: 0.69-1.34, P<0.05) in total. A total of 17 articles, including 4 567 SLA implants, were collected for the analysis of SLA implants. Meta-analysis of proportions showed that SLA implants CSR were 99% (95%CI: 98%-100%, P<0.05) in total, 99% at 5 years (95%CI: 98%-100%, P<0.05), and 99% at 10 years (95%CI: 97%-100%, P<0.05). MBL change was 0.69 mm (95%CI: 0.44-0.95, P<0.05) in total. The results of the above two studies were tested for bias (P>0.05), indicating no significant publication bias. Conclusions: Meta-analysis suggested that SLA implants have higher CSR and lower MBL than anodized implants.

Clinical study of transjugular intrahepatic portosystemic shunt with Viatorr stent in 43 cases

Objective: To investigate the clinical efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) with the use of Viator stent in the treatment of cirrhotic portal hypertension. Methods: 43 cases with cirrhotic portal hypertension were implanted with Viatorr stent during TIPS procedure from March 2016 to August 2018. Serological indicators, color Doppler ultrasound, gastroscopy, rebleeding, ascites and hepatic encephalopathy were regularly followed up. Portal venous pressure, liver and kidney function, coagulation indexes were compared by t-test. Stent patency rate, hepatic encephalopathy incidence, rebleeding rate and survival rate were calculated by Kaplan-Meier curve. Results: TIPS procedure success rate was 100% in all patients. Portal pressure gradient was decreased from (25.57 ± 5.50) mmHg to (9.76 ± 2.92) mmHg before and after operation. Alanine aminotransferase (ALT) was significantly higher at 1 month after operation than before operation, but there was no significant difference between 3 and 6 months after and before operation. Total bilirubin, serum ammonia and prothrombin time at 1, 3, and 6 months after operation were higher than before operation. Albumin had no significant change compared with before operation, and creatinine and urea nitrogen were lower than before operation. The cumulative rebleeding rates at 12 and 24 months after operation was 0% and 9%, respectively. Of the 26 patients with ascites, 22 cases (84.6%) had complete disappearance of ascites and 3 (11.5%) had significant decrease of ascites. The cumulative incidence of hepatic encephalopathy at 3, 6, 12 and 24 months after surgery was 11.6%, 17.3%, 21.9% and 21.9%, respectively. The cumulative incidence of stent dysfunction at 12 and 24 months after surgery was 5.6% and 23.7%, respectively. The cumulative survival rate at 12 months and 24 months after surgery was 91.9%. Conclusion: TIPS procedure with Viatorr stent can effectively reduce portal pressure and rebleeding rate, improve intrahepatic shunt patency rate, and will not increase the risk of postoperative hepatic encephalopathy, and has a higher cumulative survival rate.

Prognostic value of serum albumin-to-creatinine ratio in patients with acute myocardial infarction: Results from the retrospective evaluation of acute chest pain study.

The long-term association between serum albumin-to-creatinine ratio (sACR) and poor patient outcomes in acute myocardial infarction (AMI) remains unclear. This study aimed to determine whether sACR was a predictor of poor long-term survival in patients with AMI.This was a study of patients with AMI in the emergency department (ED) from the retrospective multicenter study for early evaluation of acute chest pain (REACP) study. The patients were categorized into tertiles (T1, T2, and T3) based on the admission sACR (0.445 and 0.584 g/μmol). Baseline sACR at admission to the ED was predictive of adverse outcomes. The primary outcome was all-cause mortality within the follow-up period. Cox proportional hazards models were performed to investigate the association between sACR and all-cause mortality in patients with AMI.A total of 2250 patients with AMI were enrolled, of whom 229 (10.2%) died within the median follow-up period of 10.7 (7.2–14.6) months. Patients with a lower sACR had higher all-cause mortality and adverse outcomes rates than patients with a higher sACR. Kaplan–Meier survival analysis showed that patients with a higher sACR had a higher cumulative survival rate (P < .001). Cox regression analysis showed that a decreased sACR was an independent predictor of all-cause mortality [T2 vs T1: hazard ratio (HR); 0.550, 95% confidence interval (95% CI), 0.348–0.867; P = .010 and T3 vs T1: HR, 0.305; 95% CI, 0.165–0.561; P < .001] and cardiac mortality (T2 vs T1: HR, 0.536; 95% CI, 0.332–0.866; P = .011 and T3 vs T1: HR, 0.309; 95% CI, 0.164–0.582, P < .001).The sACR at admission to ED was independently associated with adverse outcomes, indicating that baseline sACR was a useful biomarker to identify high-risk patients with AMI at an early phase in ED.

Atypical clinical manifestations and prognosis analysis of pediatric diffuse intrinsic pontine glioma

Objective To analyze the atypical clinical manifestations and clinical prognosis of pediatric diffuse intrinsic pontine glioma (DIPG). Methods A total of 27 patients with complete clinical data of DIPG undergoing clinical treatment at Neurosurgery Department of Beijing Tiantan Hospital, Capital Medical University from November 2015 to November 2017 were retrospectively enrolled into this study. All patients were divided into 2 groups according to the presence of atypical manifestations: atypical clinical manifestation group (17 cases) and the control group (10 cases). Among the 27 cases, 16 patients underwent stereotactic biopsy or open cranial biopsy, and the other 11 patients underwent tumor excision through craniotomy. All the children were followed up clinically or by telephone after operation to study the clinical outcomes. Comparative analysis was conducted on those clinical data. Prognosis was compared between the 2 groups through Kaplan-Meier survival analysis. Results Among the 27 cases, 20 were pathologically identified as high grade gliomas (including 4 cases of diffuse midline glioma, 6 cases of glioblastoma, 6 cases of anaplastic oligoastrocytoma, 4 cases of anaplastic astrocytoma) and 7 as low grade glioma (including 4 cases of oligoastrocytoma and 3 cases of astrocytoma). One child suffered from pneumonia and finally recovered postoperatively. No statistically significant difference (all P>0.05) was identified between 2 groups in the age, gender, clinical manifestation (including cranial nerve palsy, long tract dysfunction and cerebellum signs), clinical imaging features (including lesion enhancement, supratentorial ventricle enlargement and brachium pontis involvement), clinical treatment or pathology. Kaplan-Meier survival analysis showed that patients with atypical clinical manifestation had significantly higher cumulative survival rate than those in the control group (P=0.045). Conclusion Atypical clinical manifestation could be identified in some pediatric DIPG patients, which might be predictive of a better prognosis.
