Objectives: Endometriosis-associated ovarian cancer (EAOC) patients show different clinical characteristics compared with non-EAOC patients. However, a few studies are focused on the imaging characteristics of EAOC until now. We assessed MRI characteristics in differentiating EAOC and non-EAOC. Methods: We retrospectively analyzed clinical and MRI characteristics from 54 patients with 67 lesions diagnosed with primary epithelial ovarian carcinoma at the Third Affiliated Hospital of Guangzhou Medical University between January 2012 and October 2020. We studied MRI findings such as maximum diameter, morphology, configuration, locularity, features of mural nodules, lymphadenopathy, peritoneal implants, the presence of hyperintensity on T1WI, and hypointensity on T2WI. We also studied the clinical characteristics. Significant MRI variables in univariate analysis were selected for subsequent multivariate regression analysis. This study evaluated the diagnostic performance of the significant MRI variables in univariate analysis. Results: We found that the patients with EAOC, compared with those with non-EAOC, were younger, more unilateral, and had earlier FIGO stage. Univariate analysis revealed that morphology, locularity, growth pattern of mural nodules, and hypointensity on T2WI were factors that significantly differed between EAOC and non-EAOC. In the multivariate logistic regression analysis, locularity and hypointensity on T2WI were independent predictors to distinguish EAOC from non-EAOC. Conclusions: EAOC typically presented as a unilocular mass with hypointensity on T2WI in cystic components. MRI could help distinguish EAOC from non-EAOC. Advances in knowledge: MRI is a promising tool for preoperative diagnosis of EAOC.

Abstract Background and Aims Anemia is a well-know complication of Chronic Kidney Disease (CKD) and it seems to contribute for deterioration of kidney function. Experimental data suggest that anemia produces hypoxia of tubular cells which leads to tubulointerstitial damage resulting on CKD progression. Other mechanism described is that red blood cells have antioxidant properties that prevent the damage of tubulointerstitial cells and glomerulosclerosis from oxidative stress. There aren’t many observational studies that evaluated the association between anemia and progression of CKD. Therefore, our aim was to evaluate the association of anemia and CKD progression and its association outcomes in an outpatient ND-CKD population. Method We conduct a retrospective, patient-level, cohort analysis of all adult ND-CKD patients evaluated in an outpatient nephrology clinic over a 6 years period. The follow up time was at least 12 months. Anemia was defined according to the WHO definition (hemoglobin [hb] < 13.0 g/dL in men and 12.0 g/dL in women). Progression of CKD was defined by one of the following criteria: decline in eGFR (CKD-EPI) superior to 5 ml/min/1.73 m2/year; duplication of serum creatinine or the need renal replacement therapy. Demographics and clinical data were also accessed. Results Out of 3008 patients referred to the nephrology clinic, 49.9% had anemia (mean age 71.9±15.9 years; 50.4% male; 92% white; mean follow-up time of 2.3±1.2 years). The mean Hb was 11.8 ±1.9 g/dL. Important cardiovascular comorbidities in patients with anemia were arterial hypertension (86.7%), obesity (65.5%), Diabetes Mellitus (DM) (52%) and dyslipidemia (46%). In univariate analysis, mortality was associated with anemia (36.9 vs 13.0%, p<0.001), obesity (30.1 vs 21.8%, p<0.001) and DM (30.1 vs 21.1%, p<0.001). Of the patients with anemia, 738 met the criteria for CKD progression. In univariate analysis, CKD progression was associated with anemia (49.6 vs 43.9%, p=0.002), male gender (49.5 vs 43.6% p= 0.001); DM (49.6 vs 44.8 % p=0.009) and hypertension (47.9 vs 42.3% p=0.0018). In multivariate logistic regression analysis, anemia emerged was an independent predictor of CKD progression (OR 1.435, CI 95% 1.21-1.71, p<0,001). Comparing hb values intervals (hb ≤10g/dl; hb10-12 g/dL; hb ≥12 g/dL), in the multivariate logistic regression analysis, hb ≤10g/dl was not associated with CKD progression and hb value between 10-12 g/dL was associated (OR 1,486, CI 95% 1.23-1.80, p<0,001), when compared with the group with hb ≥12g/dL. In multivariate logistic regression analysis, the independent predictors of mortality were: older age (OR per 1 year increase: 1.048, 95% CI 95% 1.04-1.06, p<0.001); arterial hypertension (OR 0.699 CI 95% 0.51-0.96, p=0.0029); obesity (OR 0.741, CI 95% 0.60-0.91, p=0.004) and hb value (OR per 1 g/dL decrease: 1.301, CI 95% 1.23-1.38, p<0.001). Cardiovascular events were correlated with Hb levels between 10-12 g/dL (univariate analysis: OR 2.021, CI 95% 1.27-3.22, P=0.003), but not with the group with hb≤10 g/dL (univariate analysis: OR 1.837, CI 95% 0.96-3.51, P=0.066), having the group with hb ≥12g/dL was reference. Anemia was strongly associated with hospitalizations (multivariate logistic regression analysis: OR per 1 g/dL of Hb decrease: 1.256 CI 95% 1.12-1.32 p<0.001), and this strong association was also observed on the groups with hb hb≤10 g/dL (multivariate logistic regression analysis: OR 3.591 CI 95% 32.67-4.84 p<0.001) and between 10-12 g/dL (multivariate logistic regression analysis: OR 1.678 CI 95% 1.40-2.02, p<0.001) Conclusion Our study suggests that anemia, at first consultation, increases the risk for rapid CKD progression and global mortality. This study could guide us on the development of futures studies in order to prove if anemia correction can slow the progression of CKD.

Abstract Background Despite the profound impact of antiretroviral therapy in the control of AIDS mortality, central nervous system opportunistic infections remains a significant burden in AIDS patients. This retrospective study aims to elucidate the clinical characteristics, outcome and risk factors of cryptococcal meningitis (CM) poor prognosis in AIDS patients from a tertiary hospital in China. Methods Clinical data from 128 patients admitted in Beijing Ditan Hospital, Capital Medical University from November 2008 to November 2017 was collected. The cohort was stratified based on treatment outcome (effective 79%, and ineffective 21%), and Multivariate Logistic regression analysis used to identify risk factors of poor disease prognosis. Results Age, incidence of cerebral infarction, the proportion of consciousness disorder, and fasting plasma glucose was higher in the ineffective treatment group than the effective treatment group. The duration of treatment in the induction period of the ineffective group was significantly shorter than that of the effective group. Multivariate Logistic regression analysis indicated that the occurrence of cerebral hernia and consciousness disorder were risk factors for the prognosis of AIDS patients with CM infection, while the duration of treatment in the induction period was a indicative of a better prognosis in AIDS with CM infection complications. Finally, shunt decompression therapy correlated with a better disease outcome. Conclusions This retrospective study exposes the main risk factors associated with worse disease prognosis in AIDS patients with CM infection complications.

Abstract Background The aim of this study was to comprehensively evaluate the risk factors of periprocedural ischemic stroke associated with endovascular treatment of intracranial aneurysms using a real-world database. Methods From August 2016 to March 2017, 167 patients were enrolled. Univariate analysis and multivariate logistic regression analysis were used to examine the risk factors for periprocedural ischemic stroke. Results Among the 167 cases, periprocedural ischemic stroke occurred in 20 cases (11.98%). After univariate analysis, the ischemic group had a higher proportion of large (≥ 10 mm) aneurysms than the control group (45.0% vs. 23.1%, p = 0.036). The incidence of periprocedural ischemic stroke was higher in cases treated by flow diverter (21.6%) or stent-assisted coiling (11.8%) than in cases treated by coiling only (2.7%), and the differences were statistically significant (p = 0.043). After multivariate logistic regression analysis, treatment modality was the independent risk factor for periprocedural ischemic stroke. Compared with the coiling-only procedure, flow diverter therapy was associated with a significantly higher rate of periprocedural ischemic stroke (OR 9.931; 95% CI 1.174–84.038; p = 0.035). Conclusions Aneurysm size and treatment modality were associated with periprocedural ischemic stroke. Larger aneurysms were associated with increased risk of periprocedural ischemic stroke. Flow diverter therapy was associated with significantly more periprocedural ischemic stroke than the coiling procedure alone.

This study investigated the risk factors of thromboembolism (TE) in lymphoma patients undergoing chemotherapy and its clinical significance. A total of 304 lymphoma patients who received chemotherapy from January 2012 to July 2019 were retrospectively analyzed, including 111 patients with and 193 patients without TE. The clinical characteristics and related laboratory test results were compared between the 2 groups using univariate analysis, while the risk factors for TE in lymphoma patients undergoing chemotherapy were analyzed using multivariate logistic regression analysis. Univariate analysis revealed an increase in the risk of TE among lymphoma patients with chemotherapy in the following categories: female patients, patients with body mass index <18.5 or > 24, patients aged ≥60 years, those with platelet abnormality before chemotherapy, single hospital-stay patients, and Ann Arbor stage III/IV patients. Multivariate logistic regression analysis revealed that for platelet count abnormality before chemotherapy, Ann Arbor stage III/IV and female patients represented independent risk factors for TE among lymphoma patients after chemotherapy ( P < .05). For lymphoma patients treated with chemotherapy, the risk of TE occurring in women, patients with platelet abnormalities before chemotherapy, and patients at Ann Arbor stage III/IV was significantly higher compared with other patients. For these patients, we recommend prophylactic anticoagulant therapy.

Background and Objective: Hemorrhagic transformation (HT) is a major complication of acute ischemic stroke (AIS). Serum albumin is known for its neuroprotective effects and is a marker of improved AIS patient outcomes. However, it is not known whether there is a relationship between serum albumin and HT. Methods: AIS patients admitted to the Department of Neurology of West China Hospital from 2012 to 2016 were prospectively and consecutively enrolled. Baseline characteristics were collected. HT during hospitalization was diagnosed by brain imaging. Multivariate logistic regression analysis was performed to determine the relationship between serum albumin and HT. Confounding factors were identified by univariate analysis. Stratified logistic regression analysis was performed to identify effect modifiers. Results: A total of 1996 AIS patients were recruited, of whom 135 (6.8%) developed HT. Serum albumin negatively correlated with HT. Patients in the upper serum albumin tertile (42.6–54.1 g/L) had a 46% lower risk of HT than patients in the lower tertile (19.3–39.1 g/L) after adjustment for potential confounders (OR 0.54, 95% CI 0.29–0.99, p = 0.04). Risk of HT decreased stepwise with higher serum albumin tertile (p for trend = 0.04). There was a significant interaction between serum albumin and age (p = 0.02), with no significant correlation between serum albumin and HT in patients over 60 years of age. Conclusions: Higher serum albumin is associated with lower HT risk in a dose-dependent manner in AIS patients younger than 60 years.

Background: The causes, clinical presentations and treatment outcomes of optic neuritis are distinct among different populations. Early diagnosis based on clinical presentations plays an important role in treating optic neuritis patients. Objective: The study aimed to determine clinical characteristics, treatment outcomes and predictive factors of treatment outcomes in optic neuritis patients with and without demyelinating disease. Methods: A retrospective descriptive study of optic neuritis patients carried out between January 2009 and December 2016 was done. Univariate analysis and multivariate logistic regression analysis were used to evaluate the predictive factors of treatment outcomes. Results: Among 150 patients with optic neuritis, 58 patients were diagnosed with Neuromyelitis Optica Spectrum Disease (NMOSD), 23 patients were diagnosed with Multiple Sclerosis (MS) and 69 patients were idiopathic. The age at presentation in the NMOSD group was significantly younger than the MS group and the idiopathic group. The female:male ratio was significantly lower in the idiopathic group than in the NMOSD group. The initial Best Corrected Visual Activity (BCVA) of 20/20-20/60 (p = 0.001) and the idiopathic group (p =0.030) was associated with good visual outcomes. Initial BCVA of < 20/200 (p = 0.009) and the NMOSD group (p < 0.001) was associated with poor visual outcomes. Conclusion: NMOSD is a more common cause of optic neuritis than MS in Thai population. Female patients with poor initial VA, poor response to steroids treatment, and presenting recurrent attacks are highly suspicious for NMOSD. Optic neuritis without associated demyelinating disease has a better visual outcome and lower recurrence rate.

33 patients with active, moderate-severe Graves’ ophthalmopathy (GO) received 4.5 g methylprednisolone for 12 weeks and were divided by efficacy into two groups (responsive and unresponsive). All patients and 10 controls underwent orbital MRI examination at baseline. No significant difference was seen in baseline clinical characteristics between the two GO groups. The values of exophthalmos were higher in both GO groups than in the control and were higher in the responsive group versus the unresponsive group. Compared to the unresponsive group, the responsive group had a thicker inferior rectus as well as thinner orbital fat. The inferior rectus/fat ratio was significantly higher in the responsive group versus the unresponsive group. Multivariate logistic regression analysis showed that the exophthalmos value and inferior rectus/fat ratio were significantly associated with the response to glucocorticoid (GC). ROC analysis revealed that the cut-off points of the inferior rectus/fat ratio combined with the exophthalmos value to indicate efficacy were 1.42 and 20.78. For moderate-severe GO patients with CAS > 3, the combined inferior rectus/fat ratio and exophthalmos value in MRI may be a valuable indicator to predict the response to GC therapy.

Abstract Objective: To study the incidence and risk factors of postoperative clinical delirium in critically ill elderly patients in order to devise strategies for prevention and treatment.Methods: We collected clinical data from 451 critically ill patients in the intensive care unit from four hospitals in Shanghai Pudong New Area. Postoperative delirium was measured using the Confusion Assessment Method for the ICU (CAM-ICU), and then the incidence of postoperative delirium was calculated. We used univariate analysis and multivariate logistic regression analysis to determine the risk factors associated with postoperative delirium in critically ill elderly patients.Results: Among the 451 critically ill patients, 56 had delirium after operation. The incidence of postoperative delirium was 12.4%. Univariate analysis showed that the incidence of postoperative delirium was significantly higher (P <0.05) in patients who had a past history of chronic obstructive pulmonary disease (COPD), underwent emergency surgery, were not administered intraoperative Propofol, had postoperative hypertension, were administered postoperative methylprednisolone, and did not have postoperative analgesia. Multivariate logistic regression analysis showed that age (OR=1.111, 95% CI, 1.056-1.168), surgical timing (OR=1.154, 95% CI, 1.058-7.200), and use of methylprednisolone postoperatively (OR=8.030, 95% CI, 1.050-61.408) were risk factors. Use of Propofol intraoperatively (OR=0.315, 95%CI, 0.124-0.800) was protective factors for postoperative delirium in elderly critically ill patients.Conclusion: Adavanced age, COPD history, emergency surgery, postoperative hypertension, use of methylprednisolone, and no postoperative analgesia are risk factors for postoperative delirium in critically ill elderly patients. Medical staff should be educated in evaluating delirium in postoperative patients and conducting risk assessment in order to prevent and treat the disease earlier, and reduce the incidence of delirium.

Background Postoperative sepsis is a lethal complication for percutaneous nephrolithotomy (PCNL). An early predictive model combined local and systemic conditions is urgently needed to predict infectious events. We aim to determine the preoperative predictors of sepsis after PCNL in patients with unilateral, solitary, and proximal ureteral stones. Methods A total of 745 patients who underwent PCNL between January 2012 and December 2018 were retrospectively enrolled. Sepsis was defined based on the International Sepsis Definitions in 2001, and the preoperative factors were compared between the non-sepsis and sepsis groups. Univariable analysis and multivariable logistic regression analysis were conducted to determine the predictors for sepsis after PCNL. A nomogram was generated using the predictors. Results In this study, 35 patients (4.7%) developed sepsis after PCNL. Univariate analysis showed that post-PCNL sepsis was associated with the female, lower albumin, higher globulin, lower albumin globulin ratio (AGR < 1.5), preoperative fever, leukocytosis (WBC ≥ 10,000 cells/μL), positive urine culture, leukocyturia (≥50 cells/μL) and positive urine nitrite. Multivariate logistic regression analysis suggested that AGR < 1.5 (odds ratio [OR] = 5.068, 95% confidence interval [CI] [1.135–22.624], P = 0.033), positive urine culture (OR = 3.243, 95% CI [1.162–9.047], P = 0.025), leukocytosis (OR = 3.706, 95% CI [1.444–9.512], P = 0.006) and female (OR = 2.529, 95% CI [1.127–5.672], P = 0.024) were independent risk factors for sepsis. A nomogram was generated and displayed favorable fitting (Hosmer–Lemeshow test P = 0.797), discrimination (area under receiver operating characteristic curve was 0.807), and clinical usefulness by decision curve analysis. Conclusions Patients with certain preoperative characteristics, such as female, lower AGR, positive urine culture, and leukocytosis, who undergo PCNL may have a higher risk of developing sepsis. A cautious preoperative evaluation and optimized treatment strategy should be considered in these patients to minimize infectious complications.
