RESUMO
BACKGROUND: Ultrasound-guided percutaneous cryoablation (PCA) for early-stage breast cancer (ESBC) can be performed under local anesthesia in an outpatient clinic. This study continues a pilot stage to examine local control, safety, patient quality of life (QoL), satisfaction and cosmetic outcomes of cryoablation for ESBC. METHODS: PCA was performed under local anesthesia for patients with primary ESBC, followed by radiation and endocrine therapies. Oncologic outcomes were examined by imaging (mammography, ultrasound, MRI) at baseline and 1, 6, 12, 24, 36, and 60 months post-cryoablation. EQ-VAS, EQ-5D-5L, subjective satisfaction and Moiré topography were used to measure health-related QoL outcomes. RESULTS: Eighteen patients, mean aged 59.0 ± 9.0 years, mean tumor size 9.8 ± 2.3 mm, ER + , PR + (17/18), HER2-, Ki67 < 20% (15/18), underwent PCA and were followed for a mean of 44.3 months. No serious adverse events were reported, and no patients had local recurrence or distant metastasis in the 5-year follow-up. Cosmetic outcomes, satisfaction level, and QoL all improved post-cryoablation. Five-year average reduction rates of the cryolesion long, short, and depth diameters, on US, were 61.3%, 42.3%, and 22.8%, respectively, compared to the 86.2% volume reduction rate on MRI. The correlation coefficient between MRI and US measurement criteria was highest for the long diameter. During follow-up, calcification of the treated area was observed in 13/18 cases. CONCLUSION: Cryoablation for ESBC is an effective and safe procedure with excellent cosmetic outcomes and improved QoL. This study contributes to the growing evidence supporting cryoablation as a potential standard treatment for ESBC, given compliance to pre-defined patient selection criteria.

This study aimed to determine whether the distance of gait training using a hybrid assistive limb (HAL) is related to the improvement of walking independence in patients with acute brain injury. This was an exploratory, observational study. Thirty patients having hemiplegia (functional ambulation category, FAC score ≤2) with acute stroke or after brain tumor surgery were included. Patients performed 4 sessions of gait training using HAL (60 min/session), 1-3 sessions/week, combined with conventional physical therapy. The gait distance achieved in the four training sessions using HAL was measured. FAC score was measured before and after intervention. Patients were divided into groups A, B, and C, for FAC score improvements of 0, 1, and ≥2, respectively. Gait distance was compared among groups using one-way analysis of variance. Gait distance in group C was significantly longer than that ingroup A [mean (standard deviation): 2527 (1725) m vs. 608 (542) m]. This study suggested that the gait distance achieved during training using the HAL may be a clinical indicator of the effectiveness of the HAL on gait training in patients with acute brain injury.Clinical trial registration number: UMIN000012764 R000014756.
RESUMO
ABSTRACT: The purpose of this study is to investigate the predictive factors of home discharge for rehabilitation patients with cancer bone metastasis.Cancer patients with bone metastasis who underwent rehabilitation between April 2014 and March 2017 were retrospectively enrolled. Data on discharge destination were collected from medical records as outcomes. Multiple regression analyses were carried out to investigate the predictive factors of home discharge.Ninety-eight patients (mean age: 68.6âyears, 42 females and 56 males) were included. Fifty patients were discharged home, 38 patients were discharged to other facilities, and 10 patients died. There were no skeletal-related events among these patients during their hospital stay. The receiver-operating curve for the predictive factors for home discharge of the Barthel Index at admission, Eastern Cooperative Oncology Group Performance Status at admission, and number of immediate family members living at home were 60 points (area under the curve [AUC]â=â0.74, sensitivityâ=â0.6400, 1-specificityâ=â0.2766), 2 score (AUCâ=â0.65, sensitivityâ=â0.5400, 1-specificityâ=â0.2222), and 1 family member (AUCâ=â0.65, sensitivityâ=â0.9592, 1-specificityâ=â0.7222), respectively.In order to plan for cancer patients with bone metastasis to be discharged home, it is important to take into consideration the patients' Barthel Index and Performance Status at the time of hospital admission and the number of immediate family members living at home.

Excessive accumulation of amyloid ß-protein (Aß) is one of the primary mechanisms that leads to neuronal death with phosphorylated tau in the pathogenesis of Alzheimer's disease (AD). Protofibrils, one of the high-molecular-weight Aß oligomers (HMW-Aßo), are implicated to be important targets of disease modifying therapy of AD. We previously reported that phenolic compounds such as myricetin inhibit Aß1-40, Aß1-42, and α-synuclein aggregations, including their oligomerizations, which may exert protective effects against AD and Parkinson's disease. The purpose of this study was to clarify the detailed mechanism of the protective effect of myricetin against the neurotoxicity of HMW-Aßo in SH-SY5Y cells. To assess the effect of myricetin on HMW-Aßo-induced oxidative stress, we systematically examined the level of membrane oxidative damage by measuring cell membrane lipid peroxidation, membrane fluidity, and cell membrane potential, and the mitochondrial oxidative damage was evaluated by mitochondrial permeability transition (MPT), mitochondrial reactive oxygen species (ROS), and manganese-superoxide dismutase (Mn-SOD), and adenosine triphosphate (ATP) assay in SH-SY5Y cells. Myricetin has been found to increased cell viability by suppression of HMW-Aßo-induced membrane disruption in SH-SY5Y cells, as shown in reducing membrane phospholipid peroxidation and increasing membrane fluidity and membrane resistance. Myricetin has also been found to suppress HMW-Aßo-induced mitochondria dysfunction, as demonstrated in decreasing MPT, Mn-SOD, and ATP generation, raising mitochondrial membrane potential, and increasing mitochondrial-ROS generation. These results suggest that myricetin preventing HMW-Aßo-induced neurotoxicity through multiple antioxidant functions may be developed as a disease-modifying agent against AD.

We report a case of right uretero-external iliac artery fistula. A 46-year-old woman diagnosed with left ovarian cancer with peritoneal dissemination underwent simple hysterectomy, bilateral adnexal removal, partial omentectomy and appendectomy. Sixteen months after the operation, a computed tomography scan showed right hydronephrosis due to the development of tumor within the pelvis. A ureteral stent was placed into the right ureter in order to preserve renal function. The ureteral stent was replaced at regular intervals. Five months after the ureteral stent placement, the patient was hospitalized urgently with gross hematuria. She was diagnosed with right uretero-external iliac artery fistula based on the angiographic examination that was conducted to detect the source of hemorrhage. She was treated successfully with endovascular stent grafting in the right external iliac artery. She has since shown no episode of hematuria.

Transurethral resection of bladder tumor (TURBT) was performed on the bladder tumor of a 68-yearold male patient. Bacillus Calmette-Guérin (BCG) intravesical therapy was performed to prevent recurrence (Immunobladder : âR 80 mg once/week×6 times). A 40 mm tumor was noted in the left kidney by renal ultrasound performed two months after the completion of BCGintravesical therapy. Computed tomography (CT) showed non-enhanced multiple mass lesions in the left kidney. Renal tuberculous granuloma, hypovascular renal cell carcinoma or malignant lymphoma was suspected and CT-guided needle biopsy was performed. The patient was diagnosed with renal tuberculous granuloma that developed after BCGintravesical therapy as epithelioid cell granulomas were noted in the biopsy results. Treatment with anti-tuberculosis drugs was started and the tumor showed signs of shrinkage.

BACKGROUND: Although several studies have shown efficacy of nanoparticle albumin-bound (nab) paclitaxel use as a neoadjuvant treatment in breast cancer, dosage and schedules were varied or used in combination and the data are still limited for weekly regimens. We evaluated the feasibility of weekly nab-paclitaxel followed by FEC (5-FU [fluorouracil], epirubicin, and cyclophosphamide) treatment feasibility as neoadjuvant chemotherapy for breast cancer. PATIENTS AND METHODS: Thirty-three patients with no previous chemotherapy were enrolled to receive nab-paclitaxel 150 mg/m2 the first 3 of 4 weeks (3q4w) followed by FEC as neoadjuvant treatment. The trial was powered for analyses of feasibility. RESULTS: Twenty-five patients completed the treatment as per protocol, and the completion rate was 75.8% (95% confidence interval, 59.0-87.2; P = .44). The regimen completion group was younger than those with regimen incompletion (average 45.1 vs. 56.6 years). The pathological complete response (ypT0-is/N0) rate was 30.3% in 33 patients, which was higher in triple-negative patients (58.3%). Grade 3/4 neutropenia was seen in 48.5%, although there was no febrile neutropenia. Grade 3 peripheral neuropathy was seen in 33.3%. CONCLUSION: Our study showed that weekly nab-paclitaxel 150 mg/m2 3q4w followed by FEC as neoadjuvant regimen might be sufficient in efficacy, although with a relatively high severe adverse event occurrence rate.

BACKGROUND: It has been reported that drugs which promote the N-Methyl-D-aspartate-type glutamate receptor function by stimulating the glycine modulatory site in the receptor improve negative symptoms and cognitive dysfunction in schizophrenia patients being treated with antipsychotic drugs. METHODS: We performed a placebo-controlled double-blind crossover study involving 41 schizophrenia patients in which D-cycloserine 50 mg/day was added-on, and the influence of the onset age and association with white matter integrity on MR diffusion tensor imaging were investigated for the first time. The patients were evaluated using the Positive and Negative Syndrome Scale (PANSS), Scale for the Assessment of Negative Symptoms (SANS), Brief Assessment of Cognition in Schizophrenia (BACS), and other scales. RESULTS: D-cycloserine did not improve positive or negative symptoms or cognitive dysfunction in schizophrenia. The investigation in consideration of the onset age suggests that D-cycloserine may aggravate negative symptoms of early-onset schizophrenia. The better treatment effect of D-cycloserine on BACS was observed when the white matter integrity of the sagittal stratum/ cingulum/fornix stria terminalis/genu of corpus callosum/external capsule was higher, and the better treatment effect on PANSS general psychopathology (PANSS-G) was observed when the white matter integrity of the splenium of corpus callosum was higher. In contrast, the better treatment effect of D-cycloserine on PANSS-G and SANS-IV were observed when the white matter integrity of the posterior thalamic radiation (left) was lower. CONCLUSION: It was suggested that response to D-cycloserine is influenced by the onset age and white matter integrity. TRIAL REGISTRATION: UMIN Clinical Trials Registry (number UMIN000000468 ).

AIM: Genome-wide association studies have revealed that single nucleotide polymorphism (SNP) of human leukocyte antigen (HLA)-DQ is associated with the clearance of hepatitis B surface antigen (HBsAg) in acute hepatitis B virus (HBV) infection. We examined the effects of SNPs on the development of hepatocellular carcinoma (HCC) and markers of HBV in chronic HBV infection. METHODS: The SNPs of HLA-DQ (rs2856718 and rs7453920) were determined in 299 patients with chronic HBV infection. RESULTS: In 224 hepatitis B e antigen (HBeAg)-negative patients, those with rs2856718 genotype AG + GG had significantly lower hepatitis B core-related antigen levels (P = 0.0184), less frequent treatment with nucleotide/nucleoside analogs (NAs) (P = 0.0433), and less frequent HCC development (P = 0.0256) than those with genotype AA. Multivariate analysis selected age (P = 0.0460), platelet count (P = 0.0481), γ-glutamyl transpeptidase (P = 0.0030), and nucleotide/nucleoside analog treatment (P = 0.0003) as factors independently associated with HCC development. HBeAg-negative patients with rs7453920 genotype GG had significantly lower HBsAg levels (P < 0.0001), a higher prevalence of HBV genotype C (P = 0.0063), and a lower prevalence of the wild-type basal core promoter region (P = 0.0045) than those with genotype AA + AG. Multivariate analysis selected age (P < 0.0001), platelet count (P = 0.0021), HBV DNA levels (P = 0.0314), wild type of precore region (P = 0.0015), and rs7453920 (P < 0.0001) as factors independently associated with HBsAg levels. CONCLUSION: This study revealed an association between rs2856718 and HCC development and an association between rs7453920 and HBsAg levels.
RESUMO
Cefiderocol (S-649266) is a novel parenteral siderophore cephalosporin conjugated with a catechol moiety at the third-position side chain. The in vitro activity of cefiderocol against Pseudomonas aeruginosa was enhanced under iron-depleted conditions, whereas that of ceftazidime was not affected. The monitoring of [thiazole-14C]cefiderocol revealed the increased intracellular accumulation of cefiderocol in P. aeruginosa cells incubated under iron-depleted conditions compared with those incubated under iron-sufficient conditions. Cefiderocol was shown to have potent chelating activity with ferric iron, and extracellular iron was efficiently transported into P. aeruginosa cells in the presence of cefiderocol as well as siderophores, while enhanced transport of extracellular ferric iron was not observed when one of the hydroxyl groups of the catechol moiety of cefiderocol was replaced with a methoxy group. We conclude that cefiderocol forms a chelating complex with iron, which is actively transported into P. aeruginosa cells via iron transporters, resulting in potent antibacterial activity of cefiderocol against P. aeruginosa.

BACKGROUND: Idiopathic pulmonary arterial hypertension (IPAH) is a progressive and fatal cardiovascular disease if left untreated. In patients with IPAH with psychiatric illness or other complications, careful attention is required when administering medical therapies that may affect their hemodynamics. Patients suffering from IPAH who undergo anesthesia and surgery have a high mortality and morbidity rate. We describe the treatment of intractable psychiatric symptoms with electroconvulsive therapy (ECT) in a patient with IPAH. CASE PRESENTATION: A 23-year-old woman with IPAH and type I diabetes mellitus (DM) presented with malignant catatonia. Her heart function was classified as New York Heart Association (NYHA) class III. She required a rapid cure and ECT due to various psychiatric symptoms resistant to conventional medications. Pulmonary hypertensive (PH) crisis is the most concerning complication that can be induced by the sympathetic stimulation of ECT. To avoid PH crisis, we administered oxygen using a laryngeal mask and administered remifentanil for anesthesia. We also prepared standby nitric oxide for possible PH crisis, although it was ultimately not needed. With 14 ECT sessions, her malignant catatonia was ameliorated without physical complications. CONCLUSION: ECT is an acceptable option for the treatment of medication-refractory psychiatric disturbances in patients with IPAH, provided careful management is assured to prevent or address complications.

AIMS/INTRODUCTION: The involvement of glucose-dependent insulinotropic polypeptide (GIP) on inflammation was explored in atherosclerosis and adipose tissue. Periodontal disease is a chronic inflammatory disease, and is considered one of the diabetic complications. In the present study, to examine the effect of GIP on periodontitis, we induced experimental periodontitis in glucose-dependent insulinotropic polypeptide receptor-knockout mice (GIPRKO). We also investigated the anti-inflammatory effect of GIP in a culture system. MATERIALS AND METHODS: Experimental periodontitis was induced by ligature wire in GIPRKO and C57BL/C mice. Two weeks after the ligature, immunohistological evaluation and inflammatory messenger ribonucleic acid expression in the gingiva was examined. To elucidate the role of GIP in inflammation, the effects of GIP on lipopolysaccharide-induced gene expressions in THP-1 cells were evaluated. RESULTS: Periodontitis increased inflammatory cell infiltration, macrophage accumulation and tumor necrosis factor-α and nitric oxide synthase gene expressions in the gingiva. Periodontitis in GIPRKO showed a marked increase of inflammatory cells in the gingivomucosal tissue. Mac-1-positive macrophages and the inflammatory gene expressions were significantly increased in periodontitis in GIPRKO compared with C57BL/C mice periodontitis. Immunohistochemical staining confirmed that GIP receptors were expressed in residual and infiltrated Mac-1-positive macrophages. The in vitro study showed that GIP suppressed lipopolysaccharide-induced tumor necrosis factor-α and nitric oxide synthase gene expression in a dose-dependent manner. Furthermore, the inhibitory effect of GIP on lipopolysaccharide-induced inflammatory gene expressions was at least partially through cyclic adenosine monophosphate/protein kinase A pathway. CONCLUSIONS: These results suggest the beneficial effects of GIP on periodontal disease. In diabetic patients, GIP is expected to have a direct anti-inflammatory effect on periodontitis in addition to its glucose-lowering effect.

A 26-year-old man developed a catatonic state after his grandmother's death and the Great East Japan Earthquake. He was admitted to hospital because of the prolonged severe stupor. Electroencephalography (EEG) revealed focal (F3 electrode) and generalized epileptic abnormalities. He was administered antiepileptic agents and benzodiazepines, but his stupor did not improve in spite of a reduced frequency of epileptic EEG abnormalities. His clinical his- tory did not suggest any psychotic disorders. Thereafter, extensive physical examinations were performed, but an organic cause of the stupor was not determined. For about two years, he was unable to intake food without tubal feeding, have a conversation, or move spontaneously. One day, a generalized tonic-clonic seizure (GTC) occurred spontaneously for the first time in his life, and then his stupor markedly improved. Thereafter, he could eat food spontaneously, have a fluent conversation, and move actively. After his condition had improved, we asked his parents about his developmental history, clinical history, and present state. According to clini- cal interviews including the use of PARS (Pervasive Developmental Disorders Autism Society Japan Rating Scale), DISCO (Diagnostic Interview for Social and Communication Disorders), and WAIS-III (Wechsler Adult Intelligence Scale-third edition), he was diagnosed with autistic spectrum disorder (ASD) and mild intellectual disability. It was considered that his stupor had occurred secondary to ASD. Wing et al. reported that catatonia occurred in about 17% of ASD adolescents and young adults as a later complication. It is possible that this case, without any psychotic disorders and with ASD that has been undiagnosed until young adult, progress to such a severe and prolonged catatonic state. We report this case to show that severe catatonia is possible in adolescents and young adults during the carry-over period in ASD patients.

OBJECTIVE: Delirium is a common syndrome in older patients after surgery. Although an atrophic change in the whole brain may be a potential risk factor for postoperative delirium, the anatomically specific change related to the vulnerability still remains a significant issue. DESIGN: Prospective study. SETTING: University hospital. PARTICIPANTS: 116 consecutive patients who underwent elective cardiac operations. MEASUREMENTS: Before the surgery, magnetic resonance imaging (MRI) was evaluated. The MRI data were processed to calculate the absolute volumes of the predefined region of interest using Statistical Parametrical Mapping 8 with an atlas-based method. The evaluated volume was expressed as the fraction (%) of the total intracranial volume. Postoperative delirium was diagnosed according to the DSM-IV criteria for delirium. RESULTS: Delirium developed in 19 of 116 patients (16.4%) with an age range from 58 to 84 years. Based on a comparison with the age-controlled non-delirium patients (over 57 years; n = 65), a statistically significant reduction in the gray matter volume of the delirium patients was observed in the defined gyri of the temporal and limbic lobes. Moreover, a moderate value (>0.8) of area under the curve to predict postoperative delirium was revealed by receiver operating characteristic curve analysis of the gyri of temporal lobe. CONCLUSIONS: The decreased volume of gray matter could be associated with the vulnerability to delirium after surgery. The atlas-based method would be a potential tool to pre-screen the brain structure of individual patients for the prediction of postoperative delirium.

BACKGROUND: Nipple-sparing mastectomy (NSM) is an advantageous treatment option, providing a complete cure and good cosmetic results. We tested whether NSM is a surgically and oncologically safe technique. METHODS: We evaluated the oncological outcome of 425 breasts in 413 patients who underwent NSM between January 2000 and March 2013. We retrospectively reviewed patient data and analyzed all patient characteristics as potential risk factors of recurrence at the nipple-areola complex (NAC). To confirm the oncological safety of NSM, we compared outcomes of NSM and conventional total mastectomy. RESULTS: The median follow-up time after surgery was 46.8 months (range 6-158 months). Nipple necrosis was observed in 6 cases (1.4 %). The cumulative local recurrence rate after NSM was 5.8 % (25/425 cases), similar to that of conventional total mastectomy in the same period (5.6 %, 49/878 cases). Furthermore, the cumulative local recurrence rate at the NAC was 2.3 % (10 cases). HER2-enriched tumors and young age (<40 years) were significant risk factors for recurrence at the NAC. In patients with recurrence, the site of recurrence was easily excised, and good cosmetic results were achieved in breast reconstruction cases. CONCLUSION: NSM is safe with a low complication rate. No significant difference was observed in cumulative local recurrence rate, cumulative distant disease recurrence rate, and overall survival between patients who underwent NSM or conventional total mastectomy, confirming that NSM was surgically and oncologically safe.

OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) is a common debilitating condition in many industrialized countries that increases the risk of cardiovascular disease. The aim of this study was to derive a simple and accurate screening tool for the prediction of NAFLD in the Japanese population. METHODS: A total of 945 participants, 279 men and 666 women living in Hokkaido, Japan, were enrolled among residents who attended a health check-up program from 2010 to 2014. Participants with an alcohol consumption > 20 g/day and/or a chronic liver disease, such as chronic hepatitis B, chronic hepatitis C or autoimmune hepatitis, were excluded from this study. Clinical and laboratory data were examined to identify predictive markers of NAFLD. RESULTS: A new predictive index for NAFLD, the NAFLD index, was constructed for men and for women. The NAFLD index for men = -15.5693+0.3264 [BMI] +0.0134 [triglycerides (mg/dl)], and for women = -31.4686+0.3683 [BMI] +2.5699 [albumin (g/dl)] +4.6740[ALT/AST] -0.0379 [HDL cholesterol (mg/dl)]. The AUROC of the NAFLD index for men and for women was 0.87(95% CI 0.88-1.60) and 0.90 (95% CI 0.66-1.02), respectively. The cut-off point of -5.28 for men predicted NAFLD with an accuracy of 82.8%. For women, the cut-off point of -7.65 predicted NAFLD with an accuracy of 87.7%. CONCLUSION: A new index for the non-invasive prediction of NAFLD, the NAFLD index, was constructed using available clinical and laboratory data. This index is a simple screening tool to predict the presence of NAFLD.

AIM: To evaluate the changes of shear-wave velocity (Vs) by acoustic radiation force impulse after treatment in chronic hepatitis C. METHODS: Eighty-seven patients with chronic hepatitis C were consecutively treated with combinations of interferon (IFN) plus ribavirin (RBV). Vs value (m/s) was measured with acoustic radiation force impulse before treatment, at end of treatment (EOT), 1 year after EOT, and 2 years after EOT. RESULTS: In patients with a sustained virological response (SVR) (n = 41), Vs significantly decreased at EOT [1.19 (1.07-1.37), P = 0.0004], 1 year after EOT [1.10 (1.00-1.22), P = 0.0001], and 2 years after EOT [1.05 (0.95-1.16), P < 0.0001] compared with baseline [1.27 (1.11-1.49)]. In patients with a relapse (n = 26), Vs did not significantly decrease at EOT [1.23 (1.12-1.55)], 1 year after EOT [1.20 (1.12-1.80)], and 2 years after EOT [1.41 (1.08-2.01)] compared with baseline [1.39 (1.15-1.57)]. In patients with a nonvirological response (n = 20), Vs did not significantly decrease at EOT [1.64 (1.43-2.06)], 1 year after EOT [1.66 (1.30-1.95)], and 2 years after EOT [1.61 (1.36-2.37)] compared with baseline [1.80 (1.54-2.01)]. Among genotype 1 patients, baseline Vs was significantly lower in SVR patients [1.28 (1.04-1.40)] than in non-SVR patients [1.56 (1.20-1.83)] (P = 0.0142). CONCLUSION: Reduction of Vs values was shown in SVR patients after IFN-plus-RBV therapy by acoustic radiation force impulse.

AIM: To investigate associations between patatin-like phospholipase domain-containing 3 (PNPLA3) genotypes and fibrosis and hepatocarcinogenesis in Japanese chronic hepatitis C (CHC) patients. METHODS: Two hundred and thirty-one patients with CHC were examined for PNPLA3 genotypes, liver stiffness measurements (LSM), and hepatocellular carcinoma (HCC) from May 2010 to October 2012 at Fujita Health University Hospital. The rs738409 single nucleotide polymorphism (SNP) encoding for a functional PNPLA3 I148M protein variant was genotyped using a TaqMan predesigned SNP genotyping assay. LSM was determined as the velocity of a shear wave (Vs) with an acoustic radiation force impulse. Vs cut-off values for cirrhosis were set at 1.55 m/s. We excluded CHC patients with a sustained virological response or relapse after interferon treatment. RESULTS: PNPLA3 genotypes were CC, CG, and GG for 118, 72, and 41 patients, respectively. Multivariable logistic regression analysis selected older age (OR = 1.06; 95% CI: 1.03-1.09; p < 0.0001), higher body mass index (BMI) (OR= 1.12; 95% CI: 1.03-1.22; p = 0.0082), and PNPLA3 genotype GG (OR = 2.07; 95% CI: 0.97-4.42; p = 0.0599) as the factors independently associated with cirrhosis. When 137 patients without past history of interferon treatment were separately assessed, multivariable logistic regression analysis selected older age (OR = 1.05; 95% CI: 1.02-1.09; p = 0.0034), and PNPLA3 genotype GG (OR = 3.35; 95% CI: 1.13-9.91; p = 0.0291) as the factors independently associated with cirrhosis. Multivariable logistic regression analysis selected older age (OR = 1.12; 95% CI: 1.07-1.17; p < 0.0001), PNPLA3 genotype GG (OR = 2.62; 95% CI: 1.15-5.96; p = 0.0218), and male gender (OR = 1.83; 95% CI: 0.90-3.71); p = 0.0936) as the factors independently associated with HCC. CONCLUSION: PNPLA3 genotype I148M is one of risk factors for developing HCC in Japanese CHC patients, and is one of risk factors for progress to cirrhosis in the patients without past history of interferon treatment.
