Cholelithiasis prevalence and risk factors in individuals with severe or profound intellectual and motor disabilities. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2024; 68:317-324. [PMID: 38183322 DOI: 10.1111/jir.13113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 12/05/2023] [Accepted: 12/08/2023] [Indexed: 01/08/2024]
Abstract
BACKGROUND The prevalence and risk factors of cholelithiasis in individuals with severe or profound intellectual and motor disabilities (SPIMD) are poorly characterised. Thus, we aimed to investigate the prevalence and risk determinants of cholelithiasis in a cohort with SPIMD under medical care in a residential facility. METHODS We categorised 84 patients in a residential hospital for persons with SPIMD into groups: those with (Group CL) and without (Group N) cholelithiasis. Gallstones were detected via computed tomography, ultrasonography or both. We evaluated gastrostomy status, nutritional and respiratory support, constipation, and bladder and kidney stones. Data were significantly analysed using univariate and multivariate logistic regression analyses. RESULTS The prevalence rate of cholelithiasis in our SPIMD cohort was 27%. There were no significant differences in sex, age, weight, height, or Gross Motor Function Classification System between the two groups. However, more patients received enteral nutrition (39.13% vs. 6.56%; P = 0.000751) and were on ventilator support (56.52% vs. 19.67%; P = 0.00249) in Group CL than in Group N. Enteral nutrition [odds ratio (OR) 10.4, 95% confidence interval (CI) 1.98-54.7] and ventilator support (OR 20.0, 95% CI 1.99-201.0) were identified as independent risk factors for the prevalence of cholelithiasis in patients with SPIMD. CONCLUSIONS Patients with SPIMD demonstrated an increased prevalence of cholelithiasis, with a notable association between nutritional tonic use and respiratory support. Therefore, to emphasise the need for proactive screening, it is crucial to devise diagnostic and therapeutic strategies specific to patients with SPIMD. Further investigation is essential to validate our findings and explore causative factors.

Fetal outcomes with and without the use of sugammadex in pregnant patients undergoing non-obstetric surgery: a multicenter retrospective study. Int J Obstet Anesth 2023; 53:103620. [PMID: 36634449 DOI: 10.1016/j.ijoa.2022.103620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 12/10/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND The influence of sugammadex exposure during pregnancy on progesterone withdrawal and miscarriage is unknown. We aimed to compare the fetal outcomes in pregnant patients who had undergone non-obstetric surgery with and without sugammadex. METHODS We retrospectively reviewed the medical charts of pregnant women who underwent non-obstetric surgery at three tertiary perinatal care centers in Japan from January 2013 to December 2020. The women were divided into those who received general anesthesia with sugammadex (GA with SGX) and those who received general anesthesia without sugammadex (GA without SGX). We compared miscarriages and preterm births within four weeks after surgery. RESULTS Among the 124 women, 73 and 51 were included in the GA with SGX and GA without SGX groups, respectively. The two groups showed no differences in the rate of miscarriages or preterm births (3.0 % vs 4.3 %; odds ratio 1.42, 95 % confidence interval 0.19 to 10.47; P = 1.00). The SGX and no SGX groups were missing outcomes for 8.2 % and 7.8 % of cases, respectively. CONCLUSIONS Having GA with SGX or GA without SGX did not result in different rates of miscarriage or preterm birth within four weeks after the procedure. These findings do not exclude a potential association between sugammadex exposure during pregnancy and adverse pregnancy outcomes. Missing data may have obscured possible adverse outcomes from sugammadex exposure.

Abstract
EUSO-Balloon is a pathfinder for JEM-EUSO, the mission concept of a spaceborne observatory which is designed to observe Ultra-High Energy Cosmic Ray (UHECR)-induced Extensive Air Showers (EAS) by detecting their UltraViolet (UV) light tracks "from above." On August 25, 2014, EUSO-Balloon was launched from Timmins Stratospheric Balloon Base (Ontario, Canada) by the balloon division of the French Space Agency CNES. After reaching a floating altitude of 38 km, EUSO-Balloon imaged the UV light in the wavelength range ∼290-500 nm for more than 5 hours using the key technologies of JEM-EUSO. The flight allowed a good understanding of the performance of the detector to be developed, giving insights into possible improvements to be applied to future missions. A detailed measurement of the photoelectron counts in different atmospheric and ground conditions was achieved. By means of the simulation of the instrument response and by assuming atmospheric models, the absolute intensity of diffuse light was estimated. The instrument detected hundreds of laser tracks with similar characteristics to EASs shot by a helicopter flying underneath. These are the first recorded laser tracks measured from a fluorescence detector looking down on the atmosphere. The reconstruction of the direction of the laser tracks was performed. In this work, a review of the main results obtained by EUSO-Balloon is presented as well as implications for future space-based observations of UHECRs.

Abstract
BACKGROUND The fetal brain is vulnerable to severe and sustained hypoxia during and after birth, which can lead to hypoxic-ischemic encephalopathy (HIE). HIE is characterized by clinical and laboratory evidence of acute or subacute brain injury. The role of cytokines in the pathogenesis of brain injury and their relation to neurological outcomes of asphyxiated neonates are not fully understood. In this study, we investigated cytokine profile related to cerebral palsy (CP) with neonatal hypoxic ischemic encephalopathy (HIE) and HIE severity. METHODS Eligible subjects were HIE newborns with a gestational age between 36 and 42 weeks. We included newborns who was born at our NICU and did not admit to NICU as healthy controls. The study comprised 52 newborns, including 13 with mild to severe HIE and 39 healthy control. Serum cytokine profiles were performed using a LUMINEX cytokine kit (R&D Systems). RESULTS VEGF, MCP-1, IL-15, IL-12p70, IL-12p40, IL-1Ra, IL-2, IL-6, IL-7, IL-8, IL-10, IFN-γ, G-CSF and eotaxin in the HIE patients were significantly increased compared with the healthy neonates. In the subgroup analysis, IL-6 and G-CSF were significantly increased in CP infants (n = 5) compared with non-CP infants (n = 8). Five and eight HIE patients were classified into the mild HIE and moderate-severe HIE groups, respectively. IL-6, 10, 1Ra, and G-CSF in the moderate-severe HIE group were significantly higher than those in the mild HIE group. CONCLUSION We demonstrated that higher serum IL-6 and G-CSF at birth in HIE patients were associated with CP and moderate-severe HIE.

Abstract
The appropriate management of hepatitis B virus (HBV) infection during pregnancy has not been established in Japan. We herein report five HBV-infected pregnant Japanese women who received tenofovir disoproxil fumarate (TDF). Two of them had been born after the introduction of nationwide immunoprophylaxis and were vertically infected with HBV, highlighting the need to address mother-to-child transmission further. In both entecavir-experienced and nucleoside/nucleotide analog-naïve mothers, TDF suppressed HBV replication without serious adverse events. All five children were free from congenital disorders, growth impairment, and HBV infection. TDF showed safety and efficacy for pregnant woman with chronic hepatitis B and might have helped prevent mother-to-child transmission.

Abstract
Bilateral sagittal split ramus osteotomy (BSSRO) is commonly used in orthognathic surgery. Although abnormal sensation in areas that are innervated by the inferior alveolar nerve is a well-known neurological complication of mandibular osteotomy, facial palsy is rare postoperatively. We present a case of peripheral facial palsy that developed the day after BSSRO to correct a mandibular protrusion in a 42-year-old man. Oral prednisolone was begun on the second day postoperatively, and was gradually tapered off over time. One month after operation, he had gradually recovered all movements in his right facial muscle and, after two months, had completely recovered without residual asymmetry. Possible causes of the palsy were compression of the facial nerve as a result of the insertion of a retractor around the posterior border of the ramus, and postoperative oedema. Peripheral facial palsy after BSSRO should be considered a rare, but possible, complication and as such, should be mentioned in consent forms.

Abstract
Major depressive disorder (MDD) has been linked to differences in the volume of certain areas of the brain and to variants in the piccolo presynaptic cytomatrix protein (PCLO), but the relationship between PCLO and brain morphology has not been studied. A single-nucleotide polymorphism (SNP) in PCLO, rs2522833, is thought to affect protein stability and the activity of the hypothalamic-pituitary-adrenal axis. We investigated the relationship between cortical volume and this SNP in first-episode, drug-naive patients with MDD or healthy control subjects. Seventy-eight participants, including 30 patients with MDD and 48 healthy control subjects, were recruited via interview. PCLO rs2522833 genotyping and plasma cortisol assays were performed, and gray matter volume was estimated using structural magnetic resonance images. Among the individuals carrying the C-allele of PCLO rs2522833, the volume of the left temporal pole was significantly smaller in those with MDD than in healthy controls (family-wise error-corrected, P=0.003). No differences were detected in other brain regions. In addition, the C-carriers showed a larger volume reduction in the left temporal pole than those in the individuals with A/A genotype (P=0.0099). Plasma cortisol levels were significantly higher in MDD-affected C-carriers than in the healthy control C-carriers (12.76±6.10 vs 9.31±3.60 nm, P=0.045). We conclude that PCLO SNP rs2522833 is associated with a gray matter volume reduction in the left temporal pole in drug-naive, first-episode patients with MDD carrying the C-allele.

Abnormal asymmetries in subcortical brain volume in schizophrenia. Mol Psychiatry 2016; 21:1460-6.

Abstract
Subcortical structures, which include the basal ganglia and parts of the limbic system, have key roles in learning, motor control and emotion, but also contribute to higher-order executive functions. Prior studies have reported volumetric alterations in subcortical regions in schizophrenia. Reported results have sometimes been heterogeneous, and few large-scale investigations have been conducted. Moreover, few large-scale studies have assessed asymmetries of subcortical volumes in schizophrenia. Here, as a work completely independent of a study performed by the ENIGMA consortium, we conducted a large-scale multisite study of subcortical volumetric differences between patients with schizophrenia and controls. We also explored the laterality of subcortical regions to identify characteristic similarities and differences between them. T1-weighted images from 1680 healthy individuals and 884 patients with schizophrenia, obtained with 15 imaging protocols at 11 sites, were processed with FreeSurfer. Group differences were calculated for each protocol and meta-analyzed. Compared with controls, patients with schizophrenia demonstrated smaller bilateral hippocampus, amygdala, thalamus and accumbens volumes as well as intracranial volume, but larger bilateral caudate, putamen, pallidum and lateral ventricle volumes. We replicated the rank order of effect sizes for subcortical volumetric changes in schizophrenia reported by the ENIGMA consortium. Further, we revealed leftward asymmetry for thalamus, lateral ventricle, caudate and putamen volumes, and rightward asymmetry for amygdala and hippocampal volumes in both controls and patients with schizophrenia. Also, we demonstrated a schizophrenia-specific leftward asymmetry for pallidum volume. These findings suggest the possibility of aberrant laterality in neural pathways and connectivity patterns related to the pallidum in schizophrenia.

Abstract
AIMS To elucidate varicella zoster virus (VZV)-specific cell-mediated immunity and humoral immunogenicity against live attenuated Oka varicella zoster vaccine concurrently vaccinated with 23-valent pneumococcal polysaccharide vaccine (PPSV23) in elderly people with diabetes mellitus. METHODS This double-blind randomized controlled single-centre study of 60-70-year-old people with diabetes compared immunity and safety profiles 3 months after one dose of varicella zoster vaccine or placebo. PPSV23 was immunized simultaneously. Primary analysis evaluated cell-mediated immunity using the VZV skin test. Secondary analyses were a VZV interferon-γ enzyme-linked immunospot (ELISPOT) assay and immunoadherence haemagglutination test. Adverse experiences were recorded using diary questionnaires. RESULTS By intent-to-treat analysis, 27 participants with diabetes who had been administered the vaccine were compared with 27 participants who were given a placebo. Changes in skin test scores were 0.41 ± 0.80 and 0.11 ± 0.93 (P = 0.2155), and geometric mean fold rises of the ELISPOT counts were 1.2 [95% confidence interval (CI) 0.2, 7.9] and 1.2 (95% CI 0.2, 7.3) (P = 0.989) in the vaccine and placebo groups, respectively. The geometric mean titre did not increase 3 months after vaccination in either group. No vaccination-related severe adverse experience was reported and no participant developed herpes zoster. DISCUSSION Our previous results demonstrated that varicella zoster vaccine safely enhanced VZV-specific immunity in elderly people with or without diabetes. The results of this study showed that varicella zoster vaccine can be used safely, but it cannot boost virus-specific immunity in elderly people with diabetes when administered with concurrent PPSV23. Alternative strategies are needed to prevent VZV-associated diseases in this population.

Abstract
Cold agglutinin disease (CAD) is a rare cause of anaemia in patients with systemic lupus erythematosus (SLE). CAD is usually refractory to glucocorticosteroid, and other immunosuppressive and/or cytotoxic therapies. We report the case of a 55-years old woman with SLE and CAD that did not respond to high-dose methylprednisolone, cyclosporin A, and double filtration plasma pheresis. Because several recent case reports and studies have indicated promising results of rituximab treatment for CAD and for SLE, rituximab was given weekly at 375 mg/m2in two doses. The rituximab was well tolerated, and there were no adverse effects. The hemolysis and SLE improved markedly, and the patient remained disease free eight months later. This is the first report of successful rituximab treatment of CAD in a patient with SLE. We conclude that rituximab is worth trying in such patients if they fail to respond to conventional treatment.

Abstract
BACKGROUND Reduced gray matter volumes in the superior temporal gyrus (STG) have been reported in patients with schizophrenia. Such volumetric abnormalities might denote alterations in cortical thickness, surface area, local gyrification or all of these factors. The STG can be anatomically divided into five subregions using automatic parcellation in FreeSurfer: lateral aspect of the STG, anterior transverse temporal gyrus of Heschl gyrus (HG), planum polare (PP) of the STG, planum temporale (PT) of the STG and transverse temporal sulcus. METHODS We acquired magnetic resonance imaging (MRI) 3T scans from 40 age- and sex-matched patients with schizophrenia and 40 healthy subjects, and the scans were automatically processed using FreeSurfer. General linear models were used to assess group differences in regional volumes and detailed thickness, surface area and local gyrification. RESULTS As expected, patients with schizophrenia had significantly smaller bilateral STG volumes than healthy subjects. Of the five subregions in the STG, patients with schizophrenia showed significantly and marginally reduced volumes in the lateral aspect of the STG and PT of the STG bilaterally compared with healthy subjects. The volumetric alteration in bilateral lateral STG was derived from both the cortical thickness and surface area but not local gyrification. There was no significant laterality of the alteration in the lateral STG between patients and controls and no correlation among the structures and clinical characteristics. CONCLUSIONS These findings suggest that of five anatomical subregions in the STG, the lateral STG is one of the most meaningful regions for brain pathophysiology in schizophrenia.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

Abstract
Embryo cryopreservation is one of the important technologies in various research and clinical areas. Very recently, carboxylated ε-poly-L-lysine (COOH-PLL) has been developed as a new cryoprotective regent, and we previously demonstrated that combined treatment of COOH-PLL with ethylene glycol (EG), which is a commonly used cryoprotective regent, is effective for vitrification of unfertilized mouse oocytes and pronuclear embryos. In this study, we examined different concentration of COOH-PLL and tried to vitrify the embryos at the different stages beyond the 2-cell stage using the same protocol. Embryos at the pronuclear, 2-cell, 4-cell, 8-cell, morulae, and blastocyst stages were treated with 7.5% (vol/vol) EG and 7.5% (vol/vol) COOH-PLL for 3 min and then vitrified with 15% EG (vol/vol) and 15% (vol/vol) COOH-PLL (E15P15) for 1 min by the Cryotop. The embryos except for pronuclear embryos showed low rates of survival, blastocyst, and hatched blastocysts. To improve the survival and developmental ability of the vitrified embryos, blastocysts were vitrified with different concentrations of COOH-PLL. At the results, the survival and developmental rates of vitrified blastocyst in E20P10 group were higher (98.0 ± 2.5% and 93.3 ± 4.0%) than those of the E30, E25P5, and E15P15 groups (P < 0.05). When 2-cell, 4-cell, and 8-cell embryos or morulae were vitrified with E20P10, survival, blastocyst, and hatched blastocyst rates were dramatically improved (more than 86.0%). Taken together, vitrification with 20% COOH-PLL and 10% EG is available for vitrification of mouse pre-implantation embryos at the different stages.

Abstract
Sorafenib has been a standard therapy for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. Hepatic arterial infusion chemotherapy (HAIC) is still preferably performed in Japan because of its relatively good tumor-shrinking effect. We report a case of advanced multiple HCC with portal thrombus that responded to combination chemotherapy with sorafenib and repeat hepatic arterial infusion with a fine-powder formulation of cisplatin (IA-call®). A 57-year-old man presented for the treatment of HCC with alcoholic cirrhosis. Multiple HCC were found to be rapidly progressing with portal thrombosis. HAIC with IA-call® was performed, but the tumors progressed. TAE was performed 3 times thereafter and the main tumor shrunk to some extent. A month after the last TAE, the HCC was found to progress again, and oral sorafenib was administered. A reservoir and catheter were placed and HAIC with low-dose 5-fluorouracil and cisplatin was performed for 3 cycles following 1 HAIC cycle with epirubicin and mitomycin C, which was not effective. For 10 months after initial therapy, HAIC using IA-call® has been performed once for 6 weeks. After performing HAIC with IA-call® 5 times, the serum levels of HCC tumor markers AFP and PIVKA-Ⅱdecreased, and the tumors continued to shrink and were not stained on enhanced CT scan. The patient has been alive for 23 months after the initial therapy and has maintained stable disease.

Abstract
Inhibition from binding of Cholera toxin (CT) to Chinese hamster ovary (CHO)-K1 cells and ganglioside GM1 by lactoferrin (Lf) and kappa-casein glycomacropeptide (GMP) from cow's milk was examined. Both Lf and GMP effectively reduced the CT-derived morphological changes in CHO-K1 cells. The competitive binding assay demonstrated that both Lf and GMP inhibited the binding of CT to GM1, although their affinity for CT was lower than that of GM1. The inhibitory effect of Lf and GMP seemed to be attributed to their terminal sialic acid, although the sugar chain sequence only partially fitted to the CT-receptor.

Abstract
Several kinds of modified chymotrypsin were prepared with water-soluble acylating reagents, and their characteristics after hydrolyzing with unmodified chymotrypsin in aqueous-N,N'-dimethylformamide (DMF) media were compared. It was found that chymotrypsin (Csin), of which a 20% amino group was modified with a benzyloxycarbonyl group (Z(20)Csin), had more favorable characteristics than unmodified chymotrypsin with regard to hydrolytic activity in an aqueous DMF media. We also investigated the Z(20)Csin-catalyzed peptide synthesis in two different solution systems. In the one-layer system containing water and DMF, Z(20)Csin catalyzed the peptide bond formation in a higher yield than that by unmodifide chymotrypsin and enabled a synthetic reaction in even an 80% (v/v) DMF media, in which the hydrolytic reaction could not be carried out. Z(20)Csin catalyzed the condensation between some N-acyl amino acids or peptide derivatives and amino acids in 90% ethylacetate, 90% hexane or 50% benzene. This latter method employs a two-layer system, and the modified enzyme may be able to reduce the number of synthetic steps when preparing acyl peptides.

Abstract
A 79-year-old woman with a history of pyothorax was admitted with a 4-day history of abdominal distension. Physical examination revealed marked abdominal distention, absent bowel sounds, and a vesicular rash over the left Th8-10 dermatome. Abdominal radiography showed gaseous distension of the colon and ileum. Colonoscopy excluded any obstructive process of the colon. Laboratory findings yielded positive results for serum IgM and IgG against the varicella zoster virus (VZV) . Paralytic ileus associated with the VZV was therefore diagnosed. The ileus improved after conservative treatment with intravenous acyclovir. Although shingles is frequently encountered, it is a rare cause of paralytic ileus. In the future, the VZV should be considered as one of the causes of paralytic ileus, and complete resolution can be achieved with conservative management.

Abstract
Case 1 involved a 63-year-old woman who had multiple hepatocellular carcinomas (HCC) associated with hepatitis C virus infection. She was treated with hepatic arterial infusion chemotherapy (HAIC) and transcatheter arterial chemoembolization (TACE), followed by oral administration of sorafenib (200 mg/day). However, a lesion on the left lateral segment of the liver enlarged rapidly. Laparoscopic left lateral sectionectomy was performed. Histopathological examination revealed combined hepatocellular and cholangiocellular carcinoma. Case 2 involved a 54-year-old man who had multiple recurrent HCCs associated with hepatitis C virus infection after undergoing hepatectomy twice. Oral administration of sorafenib (200 mg/day) was initiated. The intrahepatic lesions decreased in size, but metastasis in an enlarged lymph node behind the portal vein was suspected. Laparoscopic partial hepatectomy and lymph node dissection were performed. HCC metastasis in the lymph node and partial necrosis in the intrahepatic lesions were identified histopathologically. Case 3 involved a 56- year-old man who had multiple recurrent HCCs associated with hepatitis C virus infection. TACE was performed thrice, and oral administration of sorafenib( 400-600 mg/day) was initiated. The lesion in the right lateral segment of the liver decreased in size but lesions in the left lateral segment were enlarged. Therefore, laparoscopic left hemihepatectomy was performed.

Abstract
BACKGROUND Recently, it has been reported that the incidence of primary aldosteronism (PA) among patients with hypertension is much more frequent than previously reported. AIM In the present study, we investigated the frequency and features of PA associated with subclinical Cushing syndrome (SCS). MATERIAL AND METHODS Subjects included consecutive patients (no.=39) who were diagnosed as PA and performed adrenal venous sampling between 2003 and 2011 in our institute. RESULTS In 39 subjects who were diagnosed as PA, 29 patients were operated and 5 cases (12.8%) showed no suppression in low-dose dexamethasone suppression test. Four cases of them were demonstrated to be associated with SCS, and one was associated with overt Cushing syndrome (CS). Post-operatively, 3 cases received replacement therapy of hydrocortisone, while others did not. Pathological findings indicated the diagnosis of aldosterone-producing adenoma in 4 cases associated with SCS, and of idiopathic hyperaldosteronismin in one case associated with overt CS. In all 5 cases, immunohistochemical analysis demonstrated the immunoreactivities of both 3βHSD and P450c17 in the adrenocortical tumors, the marked cortical atrophy in the zona fasciculata and reticularis, the decreased dehydroepiandrosterone sulfotransferase expression, and suppression of hypothalamo- pituitary-adrenal axis indicating the autonomous secretion of cortisol from the tumor. CONCLUSIONS The present study suggests that PA is frequently associated with SCS with prevalence of more than 10%, justifying the routine examinations for SCS in PA cases.

Abstract
Sgf29, a component of the SPT-ADA-GCN5 acetyltransferase (SAGA) complex, binds H3K4me2/3 marks and leads to histone H3 acetylation. Previously, we found that downregulation of Sgf29 suppresses c-Myc-mediated malignant transformation. Nonetheless, the upstream regulator of the Sgf29 gene is not yet known. Here, we report that Sry (sex-determining region Y), an HMG (high-mobility group) domain containing transcription factor, directly upregulates Sgf29 gene expression. Sry expression was deregulated in two out of the four tested male rodent hepatocellular carcinoma (rHCC) cell lines. Luciferase reporter and chromatin immunoprecipitation assays indicated that Sry could bind HMG-boxes in the proximal promoter region of the Sgf29 gene. Knockdown of Sry robustly lowered anchorage-independent growth, invasiveness and tumorigenicity of rHCC cells, whereas ectopic expression of Sry conferred more malignant properties. Thus, these data show that Sry is involved in male-specific malignant conversion of rHCCs via Sgf29 upregulation.

Abstract
A measurement of (2)H spin-lattice relaxation time, T(1), forD(2)O was performed with a high resolution liquid NMR apparatus fortwo samples of dimyristoylphosphatidylethanolamine (DMPE)-D(2)Osystem in a full hydration at varying temperatures of -20, -10, and 5 (°)C, and both components and compositions of differently boundfreezable water molecules were estimated from a best-fitted curve toexperimental inversion recovery data. A choice of the best-fitted curve wasbased on a distribution of weighted residuals for the experimental data. Asingle component was found for a temperature of -20 (°)C. At 5 (°)C, where all the freezable water exists in the liquid state, threecomponents were observed to be characterized by T(1) values ofapproximately 20, 100, and 200 ms, respectively. By comparingcompositions of these individual components with those obtained in ourprevious DSC study, it was revealed that the first and secondarycomponents are members of freezable interlamellar water and the last oneis comparable to bulk water.

Abstract
A 40's woman was hospitalized with cervical lymph node enlargement. Laboratory examinations showed elevated serum bile duct enzymes and the presence of anti-mitochondrial antibody. Abdominal ultrasonography and computed tomography showed enlargement of not only perihepatic lymph nodes, but also axillary and cervical lymph nodes. FDG-PET showed intense uptake concordant with these lymph nodes. We performed endoscopic ultrasonographic fine-needle aspiration biopsy of a perihepatic lymph node, but detected no malignant cells. We then performed liver biopsy, and obtained a histological diagnosed primary biliary cirrhosis. Systemic lymph nodes decreased together with serum bile duct enzyme levels during treatment with ursodeoxycholic acid.

Abstract
AIMS It has been recognized that blood pressure shows a seasonal variation, but it remains unknown whether diabetic nephropathy shows a seasonal variation. In the present study, we investigated the change in urinary albumin/creatinine ratio in relation to the season in Japanese patients with Type 2 diabetes. METHODS A total of 430 subjects (275 male, 155 female) with Type 2 diabetes and early nephropathy (defined by UACR 30-300 mg/g creatinine) were included. One year was divided into four seasons and each season was defined as winter (December-February), spring (March-May), summer (June-August), and fall (September-November), and systolic and diastolic blood pressure, serum creatinine levels, and the urinary albumin/creatinine ratio were examined. The estimated glomerular filtration rate was also calculated and evaluated. RESULTS The mean age (± SE) was 64.8 ± 0.8 years. The mean systolic blood pressure was significantly higher in winter than in summer (136 ± 0.68 vs. 133 ± 0.68 mmHg, P < 0.001). The urinary albumin/creatinine ratio showed a significantly higher value in winter than in summer (72.8 ± 4.4 vs. 54.6 ± 3.4 mg/g creatinine, P < 0.001). The curve of seasonal variation of this ratio showed a similar change to that of systolic blood pressure. No significant seasonal variation was observed in estimated glomerular filtration rate and diastolic blood pressure. CONCLUSIONS Our results suggest that there is a hitherto unknown seasonal variation in the urinary albumin/creatinine ratio, and that it may be necessary to consider this seasonal change, especially when performing an intervention study of nephropathy.

Abstract
AIM Effect of re-treatment for pegylated interferon (PEG-IFN) plus ribavirin was not fully evaluated. We examined the effects of re-treatment with PEG-IFN plus ribavirin in patients with high viral loads of genotype 1 hepatitis C virus who failed to achieve a sustained virological response (SVR) with combination therapy. METHODS We examined 38 patients who were re-treated with PEG-IFN α2a plus ribavirin for more than 60 weeks, among whom 14 were non-responders and 24 were relapsers after previous treatment with PEG-IFN α2b plus ribavirin. IL28B genotyping was done in 21 patients. RESULTS The overall SVR rate was 34%. Analysis of baseline characteristics showed that the relapsers had a significantly higher SVR rate than the non-responders (50.0%, 12/24 vs. 7.1%, 1/14, respectively, P = 0.012) The SVR rates of re-treated patients who had turned hepatitis C virus (HCV) RNA-negative at weeks 8, 12, 24, and 48 of the previous therapy were 67% (4/6), 67% (4/6), 29% (2/7), and 25% (1/4), respectively. Re-treatment achieved an SVR in five of 12 patients with IL28B major alleles and three of nine patients with IL28B minor alleles. During the re-treatment, patients with complete viral suppression at week-12 achieved a significantly higher SVR rate (P = 0.001). CONCLUSIONS Re-treatment with PEG-IFN α2a plus ribavirin therapy is effective in patients who relapse after a course of PEG-IFN α2b plus ribavirin therapy. Re-treatment is a particularly useful option for patients who achieve early viral clearance during previous therapy.

Abstract
Replication-competent retrovirus (RCR) vectors have been shown to achieve significantly enhanced tumor transduction efficiency and therapeutic efficacy in various cancer models. In the present study, we investigated RCR vector-mediated prodrug activator gene therapy for the treatment of malignant mesothelioma, a highly aggressive tumor with poor prognosis. RCR-GFP vector expressing the green fluorescent protein marker gene successfully infected and efficiently replicated in human malignant mesothelioma cell lines, as compared with non-malignant mesothelial cells in vitro. In mice with pre-established subcutaneous tumor xenografts, RCR-GFP vector showed robust spread throughout entire tumor masses after intratumoral administration. Next, RCR-cytosine deaminase (RCR-CD), expressing the yeast CD prodrug activator gene, showed efficient transmission of the prodrug activator gene associated with replicative spread of the virus, resulting in efficient killing of malignant mesothelioma cells in a prodrug 5-fluorocytosine (5FC)-dose dependent manner in vitro. After a single intratumoral injection of RCR-CD followed by intraperitoneal administration of 5FC, RCR vector-mediated prodrug activator gene therapy achieved significant inhibition of subcutaneous tumor growth, and significantly prolonged survival in the disseminated peritoneal model of malignant mesothelioma. These data indicate the potential utility of RCR vector-mediated prodrug activator gene therapy in the treatment of malignant mesothelioma.

Abstract
BackgroundAlthough longitudinal magnetic resonance imaging (MRI) studies have shown that various brain regions undergo progressive tissue loss during the early phases of schizophrenia, regional pattern of these changes remain unclear.MethodsLongitudinal MRI data were obtained from 18 (12 males and 6 females) patients with first-episode schizophrenia and 20 (11 males and 9 females) healthy controls and at baseline and follow-up with mean scan interval of 2.7 years. To compare gray matter changes over time between patients and controls were evaluated with voxel-based morphometry (VBM) using SPM8 following the longitudinal DARTEL protocol.ResultsIn both groups of patient and control longitudinal gray mater reduction was observed in various brain regions including lateral and medial frontal regions and superior temporal region. Excessive decrease in gray matter was found in patients as compared to healthy controls in the left superior temporal region and right inferior frontal region.DiscussionOur findings suggest that there are differing longitudinal gray matter changes in patients with schizophrenia during the early phases of the illness as compared to healthy individuals.

Abstract
Fibromuscular dysplasia (FMD) is a non-atheromatous, non-inflammatory, multifocal segmental angiopathy. FMD is the most common cause of pediatric renovascular hypertension. Aneurysmal formation of the main renal artery and distal branches is a rare complication of FMD in infancy. We report an 8-month-old boy with FMD presenting with shock caused by sudden renal hemorrhage that necessitated removal of one kidney. A diagnosis of renovascular hypertension resulting from intimal type FMD with aneurysmal formation was made on the basis of the presence of hypertension, elevation of PRA and aldosterone activity, pathological findings and the results of renal angiography. Our findings suggest that it is therefore necessary to consider FMD with aneurysmal formation as a possible cause of hypertension and renal hemorrhage in infants.
