Development and validation of a recurrent prediction model for patients with unilateral chronic subdural hematoma without hematoma volumetric analysis.

OBJECTIVE: Approximately 10 % of patients with chronic subdural hematoma (CSDH) undergo reoperation after initial surgery. This study aimed to develop a predictive model for the recurrence of unilateral CSDH at initial surgery without hematoma volumetric analysis. METHODS: This single-center retrospective cohort study evaluated pre- and postoperative computed tomography (CT) images of patients with unilateral CSDH. The pre- and postoperative midline shift (MLS), residual hematoma thickness, and subdural cavity thickness (SCT) were measured. CT images were classified based on the internal architecture of the hematoma (homogenous, laminar, trabecular, separated, and gradation subtypes). RESULTS: Total 231 patients with unilateral CSDH underwent burr hole craniostomy. After receiver operating characteristic analysis, preoperative MLS and postoperative SCT showed better areas under the curve (AUCs) (0.684 and 0.756, respectively). According to the CT classification of preoperative hematomas, the recurrence rate was significantly higher in the separated/gradation group (18/97, 18.6 %) than in the homogenous/laminar/trabecular group (10/134, 7.5 %). Four-point score was derived from the multivariate model using the preoperative MLS, postoperative SCT, and CT classification. The AUC of this model was 0.796, and the recurrence rates at 0-4 points were 1.7 %, 3.2 %, 13.3 %, 25.0 %, and 35.7 %, respectively. CONCLUSION: Pre- and postoperative CT findings without hematoma volumetric analysis may predict CSDH recurrence.

Associations of primary care structures with polypharmacy and patient-reported indicators in patients with complex multimorbidity: a multicentre cross-sectional study in Japan.

OBJECTIVES: Evidence supporting the effects of primary care structures on the quality of care for patients with complex multimorbidity, which is one of the most important challenges facing primary care, is scarce internationally. This study aimed to examine the associations of the types of primary care facilities with polypharmacy and patient-reported indicators in patients with complex multimorbidity, with a focus on differences between community clinics and hospitals. DESIGN: Multicentre cross-sectional study. SETTING: A total of 25 primary care facilities (19 community clinics and 6 small- and medium-sized hospitals). PARTICIPANTS: Adult outpatients with complex multimorbidity, which was defined as the co-occurrence of three or more chronic conditions affecting three or more different body systems within one person. PRIMARY OUTCOME MEASURE: Polypharmacy, the Patient-Reported Experience Measure using the Japanese version of Primary Care Assessment Tool Short Form (JPCAT-SF) and the Patient-Reported Outcome Measure using self-rated health status (SRH). RESULTS: Data were analysed for 492 patients with complex multimorbidity. After adjustment for possible confounders and clustering within facilities, clinic-based primary care practices were significantly associated with a lower prevalence of polypharmacy, higher JPCAT-SF scores in coordination and community orientation, and a lower prevalence of poor or fair SRH compared with hospital-based primary care practices. In contrast, the JPCAT-SF score in first contact was significantly lower in clinic-based practices. The associations between the types of primary care facilities and JPCAT-SF scores in longitudinality and comprehensiveness were not statistically significant. CONCLUSIONS: Clinic-based primary care practices were associated with a lower prevalence of polypharmacy, better patient experience of coordination and community orientation, and better SRH in patients with complex multimorbidity compared with hospital-based primary care practices. In the primary care setting, small and tight teams may improve the quality of care for patients with complex multimorbidity.

Association between alcohol consumption/alcohol use disorders and patient complexity: a cross-sectional study.

OBJECTIVES: The objective was to clarify the relationship between alcohol consumption/alcohol use disorders and patient complexity. DESIGN: Cross-sectional study. SETTING: A clinic located on a remote island in Okinawa, Japan, providing general outpatient practices and round-the-clock emergency services. PARTICIPANTS: Patients who lived on the island, visited Tarama Clinic from 1 April 2018 to 30 June 2018, were aged ≥20 years and had decision-making capacity were judged to be eligible for this study. MAIN OUTCOME MEASURES: Alcohol consumption/alcohol use disorders as measured by the Alcohol Use Disorders Identification Test (AUDIT) and patient complexity as scored by the Patient Centered Assessment Method (PCAM). RESULTS: During the 3-month study period, 355 patients (163 women and 192 men) with mean (SD) age of 66.4 (13.6) years were included. Multiple regression analysis of PCAM scores showed that, after adjusting for age, sex, education, occupation, physical activity, smoking, annual medical expenses and number of family members living with the patient, AUDIT scores classified as 'dependence likely' were associated with PCAM scores (p value=0.040). CONCLUSIONS: Alcohol consumption and alcohol use disorders classified as dependence likely are associated with patient complexity.

Impact of lower body mass index on risk of all-cause mortality and infection-related death in Japanese chronic kidney disease patients.

BACKGROUND: Several studies have reported that lower body mass index (BMI) is associated with high mortality in patients with chronic kidney disease (CKD). Rate of infection-related death in CKD patients is increasing. However, the relationship between BMI and infection-related death is unclear. METHODS: Overall, 2648 CKD outpatients (estimated glomerular filtration rate < 60 mL/min and/or presenting with proteinuria) under the care of nephrologists were prospectively followed for 5 years. Patients were stratified by quartile of BMI levels. Data on all-cause mortality before progression to end-stage kidney disease (ESKD) and the cause of death were collected. RESULTS: The median follow-up time was 3.9 years (interquartile range, 1.7-5.0); 114 patients died and 308 started renal replacement therapy. The leading causes of death were as follows; cardiovascular (41%), infection-related (21%), and malignancy-related (18%). Advanced age and lower BMI were the significant risk factors for all-cause mortality before progression to ESKD. Advanced age was statistically associated with respective causes of death, while lower BMI was associated with infection-related death only. CKD stage had no significant impact on all-cause or individual mortality. CONCLUSIONS: Low BMI was associated with significant risk of all-cause mortality and infection-related death, which may indicate the novel clinical target to improve CKD outcomes.

Depression and anxiety in pet owners after a diagnosis of cancer in their pets: a cross-sectional study in Japan.

OBJECTIVE: To determine the presence and predictors of depression and anxiety in pet owners after a diagnosis of cancer in their pets. DESIGN: Cross-sectional study. SETTING: A veterinary medical centre specialised in oncology for dogs and cats and two primary veterinary clinics in Japan. PARTICIPANTS: The participants for analysis were 99 owners of a pet with cancer diagnosis received in the past 1-3 weeks and 94 owners of a healthy pet. MAIN OUTCOME MEASURES: Self-reported questionnaires were used to assess depression and anxiety. Depression was assessed using the Center of Epidemiologic Studies Depression Scale, and anxiety was measured by using the State-Trait Anxiety Inventory-Form JYZ. RESULTS: Depression scores were significantly higher in owners of a pet with cancer than owners of a healthy pet, even after adjustment for potential confounders (p<0.001). Within the owners of a pet with cancer, depression was significantly more common in those who were employed than those who were unemployed (p=0.048). State anxiety scores were significantly higher in owners of a pet with cancer than owners of a healthy pet, even after adjustment for potential confounders, including trait-anxiety scores (p<0.001). Furthermore, in owners of a pet with cancer, state anxiety was higher in owners with high trait anxiety (p<0.001) and in owners whose pets had a poor prognosis (p=0.027). CONCLUSION: The results indicate that some owners tended to become depressed and anxious after their pets had received a diagnosis of cancer. Employment may be a predictor of depression. High trait anxiety and a pet with a poor prognosis may increase owners' state anxiety. Including the pet in a family genogram and attention to the pet's health condition may be important considerations for family practice.

A grading system that predicts the risk of dialysis induction in IgA nephropathy patients based on the combination of the clinical and histological severity.

Histological classification is essential in the clinical management of immunoglobulin A nephropathy (IgAN). However, there are limitations in predicting the prognosis of IgAN based on histological information alone, which suggests the need for better prognostic models. Therefore, we defined a prognostic model by combining the grade of clinical severity with the histological grading system by the following processes. We included 270 patients and explored the clinical variables associated with progression to end-stage renal disease (ESRD). Then, we created a predictive clinical grading system and defined the risk grades for dialysis induction by a combination of the clinical grade (CG) and the histological grade (HG). A logistic regression analysis revealed that the 24-h urinary protein excretion (UPE) and the estimated glomerular filtration rate (eGFR) were significant independent variables. We selected UPE of 0.5 g/day and eGFR of 60 ml/min/1.73 m2 as the threshold values for the classification of CG. The risk of progression to ESRD of patients with CG II and III was significantly higher than that of patients with CG I. The patients were then re-classified into nine compartments based on the combination of CG and HG. Furthermore, the nine compartments were grouped into four risk groups. The risk of ESRD in the moderate, high, and super-high-risk groups was significantly higher than that in the low-risk group. Herein, we are giving a detailed description of our grading system for IgA nephropathy that predicted the risk of dialysis based on the combination of CG and HG.

Incidence and Factors Associated With the Occurrence of Pulmonary Vein Narrowing After Cryoballoon Ablation.

BACKGROUND: In contrast with traditional radiofrequency ablation, little is known about the influence of cryoballoon ablation on the morphology of pulmonary veins (PVs). We evaluated the influence of cryoballoon ablation on the PV dimension (PVD) and investigated the factors associated with a reduction of the PVD. METHODS AND RESULTS: Seventy-four patients who underwent cryoballoon ablation for paroxysmal atrial fibrillation were included in the present study. All subjects underwent contrast-enhanced computed tomography both before and at 3 months after the procedure. The PVD (cross-sectional area) was measured using a 3-dimensional electroanatomical mapping system. Each PV was evaluated according to the PVD reduction rate (ΔPVD), which was calculated as follows: (1-post-PVD/pre-PVD)×100 (%). Ninety-two percent of the PVs (271/296) were successfully isolated only by cryoballoon ablation; the remaining 8% of the PVs required touch-up ablation and were excluded from the analysis. Mild (25%-50%), moderate (50%-75%), and severe (≥75%) ΔPVD values were observed in 87, 14, and 3 PVs, respectively, including 1 case with severe left superior PV stenosis (ΔPVD: 94%) in a patient who required PV angioplasty. In multivariable analysis, a larger PV ostium and lower minimum freezing temperature during cryoballoon ablation were independently associated with PV narrowing (odds ratio, 1.773; P=0.01; and odds ratio, 1.137; P<0.001, respectively). CONCLUSIONS: A reduction of the PVD was often observed after cryoballoon ablation for atrial fibrillation. A larger PV ostium and lower minimum freezing temperature during cryoballoon ablation were associated with an increased risk of PVD reduction.

Simplified criteria for diagnosing superficial esophageal squamous neoplasms using Narrow Band Imaging magnifying endoscopy.

AIM: To simplify the diagnostic criteria for superficial esophageal squamous cell carcinoma (SESCC) on Narrow Band Imaging combined with magnifying endoscopy (NBI-ME). METHODS: This study was based on the post-hoc analysis of a randomized controlled trial. We performed NBI-ME for 147 patients with present or a history of squamous cell carcinoma in the head and neck, or esophagus between January 2009 and June 2011. Two expert endoscopists detected 89 lesions that were suspicious for SESCC lesions, which had been prospectively evaluated for the following 6 NBI-ME findings in real time: "intervascular background coloration"; "proliferation of intrapapillary capillary loops (IPCL)"; and "dilation", "tortuosity", "change in caliber", and "various shapes (VS)" of IPCLs (i.e., Inoue's tetrad criteria). The histologic examination of specimens was defined as the gold standard for diagnosis. A stepwise logistic regression analysis was used to identify candidates for the simplified criteria from among the 6 NBI-ME findings for diagnosing SESCCs. We evaluated diagnostic performance of the simplified criteria compared with that of Inoue's criteria. RESULTS: Fifty-four lesions (65%) were histologically diagnosed as SESCCs and the others as low-grade intraepithelial neoplasia or inflammation. In the univariate analysis, proliferation, tortuosity, change in caliber, and VS were significantly associated with SESCC (P < 0.01). The combination of VS and proliferation was statistically extracted from the 6 NBI-ME findings by using the stepwise logistic regression model. We defined the combination of VS and proliferation as simplified dyad criteria for SESCC. The areas under the curve of the simplified dyad criteria and Inoue's tetrad criteria were 0.70 and 0.73, respectively. No significant difference was shown between them. The sensitivity, specificity, and accuracy of diagnosis for SESCC were 77.8%, 57.1%, 69.7% and 51.9%, 80.0%, 62.9% for the simplified dyad criteria and Inoue's tetrad criteria, respectively. CONCLUSION: The combination of proliferation and VS may serve as simplified criteria for the diagnosis of SESCC using NBI-ME.

Impact of hemoglobin levels on renal and non-renal clinical outcomes differs by chronic kidney disease stages: the Gonryo study.

BACKGROUND: Anemia greatly affects the development of renal and cardiovascular outcomes in chronic kidney disease (CKD) patients. However, the impact based on CKD stage remains unclear. METHODS: We prospectively followed 2,602 Japanese CKD patients under the care of nephrologists. CKD was defined according to cause, estimated glomerular filtration rate <60 mL/min, and/or proteinuria. Patient outcomes [primary end-points: cardiovascular events (CVEs), all-cause mortality, and end-stage kidney disease (ESKD) requiring renal replacement therapy] were assessed in association with basal hemoglobin (Hb) levels (<10, 10-12 and ≥12 g/dL), stratified by CKD stages. RESULTS: During follow-up, 123 patients developed CVEs, 41 died, and 220 progressed to ESKD. For stages G3, G4 and G5, ESKD frequencies were 2.8, 64.4, and 544.8 person-years, while CVEs and death were 25.6, 45.6, and 76.3 person-years, respectively. The combined endpoint rate was significantly higher in patients with Hb <10 versus Hb 10-12 g/dL, but a higher risk for CVEs and death with Hb <10 g/dL was found only in G3 [hazard ratio (HR) 4.49, (95 % confidence interval (95 % CI) 2.06-9.80)]. In contrast, risk for ESKD with Hb <10 g/dL was found only in G4 [HR 3.08 (95 % CI 1.40-6.79)] and G5 [HR 1.43 (95 % CI 1.01-2.05)]. No increased risks with higher Hb levels were found. CONCLUSION: The impact of renal anemia of Hb <10 g/dL on clinical outcomes differed by CKD stage, with a significantly high risk for CVEs and all-cause mortality in G3 and progression to ESKD in G4 and G5.

Skeletal muscle mass is associated with severe dysphagia in cancer patients.

BACKGROUND: The purpose of this study was to assess the association between skeletal muscle mass, activities of daily living (ADLs) and severe dysphagia in cancer patients. METHODS: A nested case-control study was performed in 111 consecutive cancer patients with dysphagia who were prescribed speech therapy. Skeletal muscle mass comprising the cross-sectional area of the left and right psoas muscles was assessed via abdominal computed tomography at the third lumbar vertebral level. ADLs were evaluated by the Barthel Index. The severity of dysphagia was assessed by the Food Intake Level Scale and was characterized by non-oral feeding or oral food intake at discharge. Univariate and logistic regression analyses were applied to examine the associations between dysphagia, skeletal muscle index (SMI) and ADLs. RESULTS: There were 86 men and 25 women (mean age, 70 years). The mean SMI was 5.68 ± 1.74 cm(2)/m(2) in men and 4.43 ± 1.21 cm(2)/m(2) in women. The median Barthel Index score was 20. Thirty-three patients were on non-oral feeding at discharge. The mean SMI did not differ significantly between non-oral feeding and oral food intake groups in t-test. The median Barthel Index score was lower in the non-oral feeding group in Mann-Whitney U test. Logistic regression analysis of the severity of dysphagia adjusted for age, sex, SMI, Barthel Index score, serum albumin, cancer type and stage, and vocal cord paralysis showed that SMI was associated independently with oral food intake at discharge. Barthel Index score showed a tendency to be associated with oral food intake. CONCLUSIONS: Skeletal muscle mass is associated with severe dysphagia in cancer patients. ADLs show a tendency to be associated with severe dysphagia in cancer patients.

The C-reactive protein/albumin ratio, a novel inflammation-based prognostic score, predicts outcomes in patients with hepatocellular carcinoma.

BACKGROUND: The C-reactive protein/albumin (CRP/Alb) ratio is associated with outcomes in septic patients. We investigated the prognostic value of the CRP/Alb ratio in patients with hepatocellular carcinoma (HCC). METHODS: We retrospectively evaluated 186 newly diagnosed HCC patients and investigated the correlations among the pretreatment CRP/Alb ratio, clinicopathological parameters, and overall survival (OS). Multivariate analyses were performed to identify the clinicopathological parameters associated with OS. Subsequently, we evaluated the prognostic value of the CRP/Alb ratio compared with other inflammation-based prognostic scores [Glasgow Prognostic Score (GPS), modified GPS (mGPS), and neutrophil lymphocyte ratio (NLR)] using the area under the curve (AUC). RESULTS: The optimal cutoff level for the CRP/Alb ratio was 0.037. An elevated CRP/Alb ratio (≥0.037) was associated with tumor progression and reduced liver functional reserve. In the multivariate analysis, the CRP/Alb ratio [hazard ratio (HR) 3.394; p < 0.0001], Cancer Liver Italian Program score (HR 2.686; 95% CI 2.122-3.401; p < 0.0001), and vascular invasion (HR 3.376; 95% CI 1.594-7.151; p = 0.001) were independently associated with OS (HR 3.394; p < 0.0001). The CRP/Alb ratio had higher AUC values at 6 months (0.844), 12 months (0.863), and 24 months (0.82) compared with the GPS, mGPS, and NLR. CONCLUSION: The CRP/Alb ratio might be an independent prognostic marker in patients with HCC, and may have comparable prognostic ability to other established inflammation-based prognostic scores. The prognostic value of this novel inflammation-based prognostic score needs to be verified in patients with other types of cancer.

A feasibility study of chemically assisted endoscopic submucosal mechanical dissection using mesna for superficial esophageal squamous cell carcinomas.

BACKGROUND: Injection of mesna into submucosal layers was recently reported to chemically soften connective tissue and facilitate the gastric endoscopic submucosal dissection (ESD) procedure. This study aimed to evaluate the safety and feasibility of similarly using mesna for esophageal ESD (mesna ESD). METHODS: We performed mesna ESD in 20 consecutive patients with superficial esophageal squamous cell carcinomas (SESCCs). To do this, a submucosal fluid cushion was initially formed using sodium hyaluronate, and the esophageal lesion was circumferentially isolated with a short blade needle-knife. Mesna solution was then injected into the submucosal layer, which was dissected mechanically by cleavage using the tip of a cap-fitted endoscope. The number of electrosurgical incisions was recorded by computer software in real time. The data from 20 conventional ESD procedures without mesna (consecutive 10 SESCCs pre and post the 20 consecutive mesna ESD) were used for comparison to evaluate the mesna ESD. RESULTS: The mesna ESDs achieved en bloc and R0 resection success rates of 100 and 95 %, respectively. There was no perforation or uncontrollable hemorrhage during and after mesna ESD, and the median procedural time of submucosal dissection was significantly less with mesna ESD than with conventional ESD (median; 8 vs. 15 min, P < 0.05). There were also significantly fewer electrosurgical incisions made during the mesna ESD than with conventional ESDs (median; 65 vs. 183 times, P < 0.01). CONCLUSIONS: Mesna ESD for SESCCs is a safe procedure with the potential to facilitate esophageal ESD.

The addition of C-reactive protein to validated staging systems improves their prognostic ability in patients with hepatocellular carcinoma.

OBJECTIVES: C-reactive protein (CRP) is a practical prognostic marker in patients with hepatocellular carcinoma (HCC). We investigated the prognostic value of adding the CRP level to other validated staging systems (Cancer Liver Italian Program, Japan Integrated Staging, Barcelona Clinic Liver Cancer classification system, Tokyo score and tumor node metastasis classification) in HCC patients. METHODS: One hundred and eighty-six newly diagnosed HCC patients were retrospectively evaluated. A multivariate analysis identified the clinicopathological variables associated with overall survival; the variables identified were then added to each staging system and compared to those without the additional variable. RESULTS: In multivariate analysis, an elevated serum CRP level was independently associated with a poor prognosis (hazard ratio 3.792, p < 0.0001). The addition of the CRP level to each of the established staging systems provided a higher linear χ(2) value and a lower -2 log likelihood than those without the addition of the term. Moreover, the area under the receiver-operating characteristic curve (AUC) analysis showed that the addition of CRP improved the AUC of each staging system. CONCLUSIONS: This study demonstrates that an elevated serum CRP level is independently associated with a poor prognosis in HCC patients, and the addition of the CRP level to the validated staging systems could improve the prognostic ability of each staging system.

Preference for different anchor descriptors on visual analogue scales among Japanese patients with chronic pain.

CONTEXT: Although many previous studies have examined the preference of patients for different pain measurement scales, preference for anchor descriptors has not been thoroughly discussed. OBJECTIVES: To examine (1) the preferred end-phrases used in the VAS as anchor labels for Japanese patients with chronic pain, and (2) whether the preference differs according to factors such as age, sex, educational level, duration of pain, and pain intensity. METHODS: We performed an observational study in patients suffering from non-cancer chronic pain for more than 3 months at a pain center in Japan. The patients were asked to rate their pain intensity using four types of VAS that used the following different anchor descriptors: "worst pain" ("Worst"), "worst pain bearable" ("Bearable"), "worst pain imaginable" ("Imaginable"), and "worst pain you have ever experienced" ("Experienced"). They were also asked to rank the four scales according to ease of responding, and asked which descriptor best reflected their perceived pain. RESULTS: In total, 183 patients participated in the study. They consisted of 119 (65.0%) women and 64 (35.0%) men aged 18-84 years with the mean age of 56.9 years. "Experienced" was most preferred (69.8%), followed by "Bearable" (66.3%), "Worst" (48.8%), and "Imaginable" (16.9%). Factors such as age, sex, educational background, duration of pain, and pain intensity did not significantly affect the results. In 83.1% of patients, the preferred descriptor corresponded to the descriptor that best reflected patients' perceived pain. CONCLUSION: The frequently used expression "worst pain imaginable" is considered to be difficult to understand for most patients. Widely preferred descriptors, such as "worst pain you have ever experienced" and "worst pain bearable", should be used when evaluating perceived pain. The preference of anchor descriptors was not significantly affected by the factors such as age, sex, educational level, duration of pain, and pain intensity.

A multicenter randomized controlled trial of tonsillectomy combined with steroid pulse therapy in patients with immunoglobulin A nephropathy.

BACKGROUND: The study aim was, for the first time, to conduct a multicenter randomized controlled trial to evaluate the effect of tonsillectomy in patients with IgA nephropathy (IgAN). METHODS: Patients with biopsy-proven IgAN, proteinuria and low serum creatinine were randomly allocated to receive tonsillectomy combined with steroid pulses (Group A; n = 33) or steroid pulses alone (Group B; n = 39). The primary end points were urinary protein excretion and the disappearance of proteinuria and/or hematuria. RESULTS: During 12 months from baseline, the percentage decrease in urinary protein excretion was significantly larger in Group A than that in Group B (P < 0.05). However, the frequency of the disappearance of proteinuria, hematuria, or both (clinical remission) at 12 months was not statistically different between the groups. Logistic regression analyses revealed the assigned treatment was a significant, independent factor contributing to the disappearance of proteinuria (odds ratio 2.98, 95% CI 1.01-8.83, P = 0.049), but did not identify an independent factor in achieving the disappearance of hematuria or clinical remission. CONCLUSIONS: The results indicate tonsillectomy combined with steroid pulse therapy has no beneficial effect over steroid pulses alone to attenuate hematuria and to increase the incidence of clinical remission. Although the antiproteinuric effect was significantly greater in combined therapy, the difference was marginal, and its impact on the renal functional outcome remains to be clarified.

The Glasgow Prognostic Score accurately predicts survival in patients with biliary tract cancer not indicated for surgical resection.

The Glasgow Prognostic Score (GPS) and neutrophil to lymphocyte ratio (NLR) are associated with the survival in patients with various types of malignancy. The aim of this study was to investigate the prognostic value of the GPS and NLR in patients with biliary tract cancer (BTC) undergoing palliative chemotherapy or best supportive care (BSC). Fifty-two patients with newly diagnosed BTC were retrospectively evaluated. We investigated the correlation between the GPS, NLR, and the overall survival rates. The area under the receiver operating characteristics curve (AUC) was calculated to compare the predictive ability of each score. Both the univariate and multivariate analyses were performed to identify clinicopathological variables associated with the overall survival. There were significant differences between the GPS groups regarding the neutrophil levels (p < 0.0001), Hb (p = 0.024), Alb (p < 0.0001) and CRP (p < 0.0001). A significant difference in the overall survival was found between the groups stratified based on the GPS, NLR (p < 0.001). The GPS had a higher AUC value (0.905) in comparison to the NLR (0.648). In the multivariate analysis, the sex (p = 0.002), CA19-9 (p < 0.0001) and the GPS (p < 0.0001) were found to be independently associated with the overall survival. Our results demonstrate that the GPS is an independent marker of the prognosis in patients with BTC undergoing palliative chemotherapy or BSC, and is superior to the NLR in terms of its prognostic ability.

Overestimation of the risk of progression to end-stage renal disease in the poor prognosis' group according to the 2002 Japanese histological classification for immunoglobulin A nephropathy.

BACKGROUND: The current (2012) histological classification of immunoglobulin A nephropathy was established using a case-control study of 287 patients. However, the risk of progression to end-stage renal disease (ESRD) has not been validated for the previous (2002) classification. This study aimed to determine whether the previous classification could identify the risk of long-term renal outcome through re-analysis of the 2012 cohort. METHODS: On the basis of the 2002 classification, namely 'good prognosis', 'relatively good prognosis', 'relatively poor prognosis', and 'poor prognosis', we examined the clinical data at the time of biopsy, the correlation between the 2002 classification and long-term renal outcomes, and a patient-by-patient correlation between the 2002 and 2012 classification systems. This was performed by analyzing samples from the 287 patients used to establish the 2012 classification. RESULTS: The rate of decline of estimated glomerular filtration rate was greater and the odds ratio of progression to ESRD was higher in the 'poor prognosis' group. In contrast, the odds ratio for renal death was comparable between the groups described as 'relatively poor prognosis' and 'relatively good prognosis' in the 2002 classification. Many patients in the 2002 classification were classified with a lower histological grade in the current classification, but none were classified with a higher grade. CONCLUSIONS: The 2002 classification could also identify the risk of progression to ESRD. However, it was overestimated for patients in the 'poor prognosis' group in the 2002 classification, as that group included patients with milder histological damage.

Elevated plasma fibrinogen levels are associated with a poor prognosis in patients with hepatocellular carcinoma.

OBJECTIVES: Elevated plasma fibrinogen levels are associated with tumor progression and poor outcomes in cancer patients. We investigated the prognostic value of pretreatment plasma fibrinogen levels in patients with hepatocellular carcinoma (HCC). METHODS: One hundred and thirteen patients with newly diagnosed HCC were retrospectively evaluated. We investigated the correlation between pretreatment plasma fibrinogen levels, clinicopathological parameters and overall survival. Both univariate and multivariate analyses were performed to identify the clinicopathological parameters associated with overall survival. RESULTS: The median value of the pretreatment plasma fibrinogen level was 279 mg/dl. Elevated plasma fibrinogen levels were associated with larger tumor size, the presence of vascular invasion and higher Cancer Liver Italian Program scores. Lower plasma fibrinogen levels were associated with higher Child-Pugh grades. The overall survival rates in patients with pretreatment plasma fibrinogen levels ≥ 315 mg/dl were significantly lower than those with a pretreatment plasma fibrinogen level <315 mg/dl (p = 0.016). On multivariate analysis, the plasma fibrinogen levels (per 100 mg/dl) were found to be independently associated with overall survival (hazard ratio 1.236; p = 0.046). CONCLUSIONS: This study demonstrates that elevated pretreatment plasma fibrinogen levels are associated with tumor progression and are independently associated with a poor prognosis in patients with HCC.

The Glasgow Prognostic Score, an inflammation based prognostic score, predicts survival in patients with hepatocellular carcinoma.

BACKGROUND: Elevated Glasgow Prognostic Score (GPS) has been related to poor prognosis in patients with hepatocellular carcinoma (HCC) undergoing surgical resection or receiving sorafenib. The aim of this study was to investigate the prognostic value of GPS in patients with various stages of the disease and with different liver functional status. METHODS: One hundred and fifty patients with newly diagnosed HCC were prospectively evaluated. Patients were divided according to their GPS scores. Univariate and multivariate analyses were performed to identify clinicopathological variables associated with overall survival; the identified variables were then compared with those of other validated staging systems. RESULTS: Elevated GPS were associated with increased asparate aminotransferase (P<0.0001), total bilirubin (P<0.0001), decreased albumin (P<0.0001), α-fetoprotein (P=0.008), larger tumor diameter (P=0.003), tumor number (P=0.041), vascular invasion (P=0.0002), extra hepatic metastasis (P=0.02), higher Child-Pugh scores (P<0.0001), and higher Cancer Liver Italian Program scores (P<0.0001). On multivariate analysis, the elevated GPS was independently associated with worse overall survival. CONCLUSIONS: Our results demonstrate that the GPS can serve as an independent marker of poor prognosis in patients with HCC in various stages of disease and different liver functional status.

A histologic classification of IgA nephropathy for predicting long-term prognosis: emphasis on end-stage renal disease.

BACKGROUND: A multicenter case-control study on IgA nephropathy (IgAN) was conducted to develop an evidence-based clinicopathologic classification of IgAN for predicting long-term renal outcome. METHODS: Two hundred and eighty-seven patients including those with isolated hematuria or very mild proteinuria were enrolled. During a median follow-up of 9.3 years after biopsy, 49 patients (17%) progressed to end stage renal disease (ESRD). The associations between pathological variables and the need for chronic dialysis was examined by multivariate logistic regression analysis separately in patients who required dialysis earlier than 5 years (Early Progressors) and those who required dialysis within 5 to 10 years (Late Progressors) after biopsy. RESULTS: Independent pathological variables predicting progression to ESRD were global sclerosis, segmental sclerosis and fibrous crescents for Early Progressors, and global sclerosis and cellular/fibrocellular crescents for Late Progressors. Four histological grades, HG 1, HG 2, HG 3 and HG 4, were established corresponding to <25%, 25-49%, 50-74% and =75% of glomeruli exhibiting cellular or fibrocellular crescents, global sclerosis, segmental sclerosis or fibrous crescents. Eleven (7%) patients in HG 1, 12 (16%) in HG 2, 13 (31%) in HG 3 and 13 (68%) in HG 4 progressed to ESRD. Multivariate logistic analysis revealed that the risk of progression to ESRD was significantly higher in HG 2, 3 and 4 than in HG 1 (odds ratio, 2.4, 5.7 and 27.6 vs. 1.0). CONCLUSIONS: Our evidence-based histologic classification can identify the magnitude of the risk of progression to ESRD and is useful for predicting long-term renal outcome in IgAN.
