Abstract
A brief background discussion.
Nanoparticle albumin-bound paclitaxel (nab-PTX) has been developed under the concept of improved drug delivery. nab-PTX has been shown to significantly increase progression-free survival compared with solvent-based paclitaxel (PTX) in metastatic breast cancer. However, the long-term outcomes of nab-PTX induced peripheral neuropathy (nPIPN) have not yet been fully elucidated.
Trial design: observational cohort study (UMIN20852)
Primary objective: The long-term outcome of nPIPN
Secondary objectives
(1)The validity of the Neuropathic Pain Screening Questionnaire (Japan–Q, Ishikawa et al. Pain Research 2016 )
(2) To evaluate the effect of frozen gloves and elastic stockings for nPIPN
nPIPN was assessed by the Japan-Q (J-Q) and Common Toxicity Criteria for Adverse Events ver 4.0 (CTC). The J-Q is an assessment tool for patient-reported pain severity, which consists of seven items, each rated on a five-point scale 0-4; grade 0 (no symptoms) to grade 4 (verysevere symptoms). Pricking pain, electric shock pain, burn like pain, tingling pain with numbness, allodynia, reduced or hyper sensitivity and hand-foot syndrome. Assessment was performed every day during chemotherapy, six months and one year after completion of nab-PTX therapy. Total of 28 points for each day and 588 points for each cycle, higher point correlates with severity. Frozen gloves during administration of nab-PTX and/or elastic stockings were optionally used.
Statistical methods
Kruskal Wallis test was used and p<0.05 was considered as significant.
RESULTS:
Between May 2013, and April 2016, 105 patients were enrolled from 7 hospitals. In 73 patients (69.5%) nab-PTX was administered as primary and in 32 patients (30.5%) as adjuvant therapy. Forty three (41.0%) patients received nab-PTX as first line and 62 (59.0%) received after anthracycline contained regimen. Trastuzumab was administered as combination therapy with nab-PTX for Her2 positive patients. Both frozen gloves and stockings were used in 21 patients (20.0%) and frozen gloves only were used in 21 patients (20.0%) according to patient preference.
One hundred patients (95.2%) completed four courses, and overall relative dose intensity was 91.4%.
During chemotherapy, J-Q scores go elevated from day 1 to day 5 and gradually declined throughout the rest of the cycle. Without using frozen gloves, there was a significant increase according to courses (1st: 45.0 ± 5.7, 2nd: 76.7 ± 8.6, 3rd: 94.3 ± 11.8, 4th: 95.4 ± 11.8). Using frozen gloves, there was a significant increase from 1st course to 2nd, but no further increase was observed(1st: 37.4 ± 8.1, 2nd: 61.9 ± 12.4, 3rd: 62.9 ± 10.4, 4th: 55.3 ± 10.6). After six month and one year, the scores were significantly lower compared with the last day of the fourth cycle (4.28 ± 0.50, 2.53 ± 0.25, 2.85 ± 0.39, respectively). CTC, grade 2 or more sensory disturbance was observed in 57.9% after four cycles, but improved to 9.5% and 5.4% after six month and one year respectively.
CONCLUSIONS:
Patient-reported nPIPN was significantly getting worse without frozen gloves during chemotherapy, however be largely reversible within 1 year of PST or adjuvant treatment. The J-Q findings support that nab-PTX treatment is tolerable.

Abstract
BACKGROUND We hypothesized that, compared with propofol, desflurane prolongs the antegrade accessory pathway effective refractory period (APERP) in children undergoing radiofrequency catheter ablation for Wolff-Parkinson-White (WPW) syndrome. METHODS In this randomized crossover study, children aged 4.1-16.1 years undergoing radiofrequency catheter ablation for WPW syndrome were randomly divided into four groups according to the concentration of desflurane and anesthetics used in the first and the second electrophysiological studies (EPS). After induction of general anesthesia with propofol and tracheal intubation, they received one of the following regimens: 0.5 minimum alveolar concentration (MAC) desflurane (first EPS) and propofol (second EPS) (Des0.5-Prop group, n = 8); propofol (first EPS) and 0.5 MAC desflurane (second EPS) (Prop-Des0.5 group, n = 9); 1 MAC desflurane (first EPS) and propofol (second EPS) (Des1.0-Prop group, n = 10); propofol (first EPS) and 1 MAC desflurane (second EPS) (Prop-Des1.0 group, n = 9). Radiofrequency catheter ablation was performed upon completion of EPS. Sample size was determined to detect a difference in the APERP. RESULTS Desflurane at 1.0 MAC significantly prolonged the APERP compared with propofol, but did not affect the sinoatrial conduction time, atrio-His interval or atrioventricular node effective refractory period. Supraventricular tachycardia was induced in all children receiving propofol, but not induced in 1 and 4 children receiving 0.5 MAC and 1.0 MAC desflurane, respectively. CONCLUSION Desflurane enhances the refractoriness and may block the electrical conduction of the atrioventricular accessory pathway, and is therefore not suitable for use in children undergoing radiofrequency catheter ablation for WPW syndrome.

Abstract
To clarify the quality of life of patients who underwent esophagectomy for carcinoma by right thoracotomy, laparotomy and cervical anastomosis, 116 patients who were cancer free at the time of mailing a questionnaire were analyzed. A significant decrease in vital capacity for 3 years postoperatively, as well as in the percentage of ideal body weight, between 3 and 5 years were observed in 57 patients with three-field lymphadenectomy. Patients' quality of life undergoing three-field dissection was worse than those with less radical lymphadenectomy (59 cases) in terms of the performance status and difficulty in talking at 60 months or more postoperatively. Around 20% of all patients reported severe hoarseness due to permanent recurrent nerve paralysis, resulting in poor quantity of food intake at 24 months or less postoperatively and restricted daily activity and difficulty in talking at 60 months or more after the operation. When a patient suffers from vocal cord insufficiency caused by permanent paralysis of the recurrent nerve, early treatment before discharge from the hospital should be performed to improve the quality of life of such a patient.

Abstract
To determine whether maximum bite force (MBF), an objective measure of oral function, is associated with development of frailty in community-dwelling older adults. This prospective cohort study included community-dwelling Japanese adults aged 75 years at baseline (n = 322). Baseline MBF was measured using an electronic recording device (Occlusal Force-Meter GM10). Follow-up examinations, including physical fitness and anthropometric evaluation and structured questionnaires, were administered annually over a 5-year period to determine the incidence of frailty, which was defined by the presence of 3 or more of the following 5 components derived from the Cardiovascular Health Study: low level of mobility, low physical activity level, weakness, shrinking and poor endurance and energy. Adjusted hazard ratios (HRs) of incidence of frailty according to sex-stratified tertiles of baseline MBF were calculated using Cox proportional hazards regression models. During the follow-up, 49 participants (15.2%) developed frailty. Participants in the lower tertile of MBF exhibited a significantly greater risk of frailty than those in the upper tertile. After adjustment for sex, depression, diabetes and Eichner index, the adjusted HRs for frailty in the upper through lower tertiles of MBF were 1.00 (reference), 1.27 (95% confidence interval [CI]: 0.50-3.20) and 2.78 (95% CI: 1.15-6.72), respectively (P for trend = .01). Poor oral function, as indicated by low MBF, increases the risk of development of frailty among elderly men and women.

Abstract
A previous genome-wide association study (GWAS) performed in 963 Japanese individuals (487 primary biliary cholangitis [PBC] cases and 476 healthy controls) identified TNFSF15 (rs4979462) and POU2AF1 (rs4938534) as strong susceptibility loci for PBC. In this study, we performed GWAS in additional 1,923 Japanese individuals (894 PBC cases and 1,029 healthy controls), and combined the results with the previous data. This GWAS, together with a subsequent replication study in an independent set of 7,024 Japanese individuals (512 PBC cases and 6,512 healthy controls), identified PRKCB (rs7404928) as a novel susceptibility locus for PBC (odds ratio [OR] = 1.26, P = 4.13 × 10-9). Furthermore, a primary functional variant of PRKCB (rs35015313) was identified by genotype imputation using a phased panel of 1,070 Japanese individuals from a prospective, general population cohort study and subsequent in vitro functional analyses. These results may lead to improved understanding of the disease pathways involved in PBC, forming a basis for prevention of PBC and development of novel therapeutics.

Abstract
Background Large-scale schistosomiasis control programs are implemented in regions with diverse social and economic environments. A key epidemiological feature of schistosomiasis is its small-scale heterogeneity. Locally profiling disease dynamics including risk factors associated with its transmission is essential for designing appropriate control programs. To determine spatial distribution of schistosomiasis and its drivers, we examined schoolchildren in Kwale, Kenya. Methodology/Principal findings We conducted a cross-sectional study of 368 schoolchildren from six primary schools. Soil-transmitted helminths and Schistosoma mansoni eggs in stool were evaluated by the Kato-Katz method. We measured the intensity of Schistosoma haematobium infection by urine filtration. The geometrical mean intensity of S. haematobium was 3.1 eggs/10 ml urine (school range, 1.4–9.2). The hookworm geometric mean intensity was 3.2 eggs/g feces (school range, 0–17.4). Heterogeneity in the intensity of S. haematobium and hookworm infections was evident in the study area. To identify factors associated with the intensity of helminth infections, we utilized negative binomial generalized linear mixed models. The intensity of S. haematobium infection was associated with religion and socioeconomic status (SES), while that of hookworm infection was related to SES, sex, distance to river and history of anthelmintic treatment. Conclusions/Significance Both S. haematobium and hookworm infections showed micro-geographical heterogeneities in this Kwale community. To confirm and explain our observation of high S. haematobium risk among Muslims, further extensive investigations are necessary. The observed small scale clustering of the S. haematobium and hookworm infections might imply less uniform strategies even at finer scale for efficient utilization of limited resources. The World Health Organization is spearheading the war on neglected tropical diseases, including helminth infections, by encouraging its member states to intensify control efforts. This call has recently been answered in most endemic regions of helminthiasis and governments are scaling up chemotherapy-based control programs in collaboration with private and public partners. However, it is necessary to clearly understand factors driving local transmission dynamics of helminth infections to design effective control programs. Here, we conducted a cross-sectional survey of 368 primary schoolchildren in Kwale, Kenya, and identified factors associated with the intensity of Schistosoma haematobium and hookworm infections. The negative binomial generalized linear mixed model showed the intensity of S. haematobium infection was much higher among Muslims and schoolchildren from low socioeconomic status households. High intensity of hookworm infection was associated with sex, SES, distance to river and history of anthelmintic treatment. Our findings demonstrate considering social and cultural drivers of NTDs could be beneficial in designing of efficient control programs and expediting NTDs control.

[PMID: 28062160 DOI: 10.1016/j.ejso.2016.11.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2016] [Revised: 11/01/2016] [Accepted: 11/30/2016] [Indexed: 01/28/2023] Open
Abstract
AIMS Secreted Frizzled-Related Protein-1 (SFRP1) is a well-known negative regulator of the wingless type (Wnt)-β-catenin pathway and its inactivation plays an important role in the development and progression of many cancers. In this study, we aimed to determine the clinical significance of SFRP1 expression in intrahepatic cholangiocarcinoma (IHCC) and to define the relationship to Wnt-β-catenin pathway. METHODS Fifty IHCC patients who had liver resection were enrolled in this study. SFRP1 protein expression was examined by immunohistochemistry in tumor tissues. The patients were divided into two groups: SFRP1 positive (n = 30) and negative (n = 20). Clinicopathological characteristics were analyzed. RESULTS SFRP1 significantly correlated with curability (Cur A, B vs. C, p = 0.029); and recurrent pattern (intrahepatic vs. extrahepatic, p = 0.010). The negative SFRP1 group had significantly poorer prognosis, and 5-year survival rates were 8.1% of the negative SFRP1 group and 44.6% of the positive SFRP1 group, respectively. Moreover, the disease-free survival rate in the negative SFRP1 group was significantly poorer (p < 0.001). Multivariate analysis revealed that loss of SFRP1served as an independent prognostic factor in IHCC for both overall (HR, 2.923; 95% CI, 1.30-6.56; p = 0.009) and disease-free (HR, 2.631; 95% CI, 1.31-5.27; p = 0.006) survival. In addition, SFRP1 expression negatively correlated to β-catenin expression (p = 0.005). CONCLUSIONS Those results suggested that the loss of SFRP1 could be a poor prognostic factor for IHCC, through the Wnt-β-catenin pathway.

Abstract
Autoimmune hepatitis (AIH) is an uncommon chronic autoimmune liver disease. Several studies reported the association of polymorphisms between CD28, CTLA4 and ICOS gene cluster in 2q33.2 with autoimmune or inflammatory diseases. The previous genome-wide association study on type 1 AIH in a European population has reported a risk G allele of a single nucleotide polymorphism (SNP), rs4325730, in this region. Here, we conducted an association study of this SNP with type 1 AIH in a Japanese population, as a replication study.An association study of rs4325730 was conducted in 343 Japanese AIH patients and 315 controls.We found that rs4325730 is associated with AIH (P=0.0173, odds ratio (OR) 1.30, 95% confidence interval (CI) 1.05-1.62, under the allele model for G allele, P=0.0070, OR 1.62, 95% CI 1.14-2.31, under the dominant model for G allele). This SNP was strongly associated with definite AIH (P=0.0134, OR 1.36, 95% CI 1.07-1.74; under allele model for G, P=0.0035, OR 1.85, 95% CI 1.22-2.81, under dominant model for G).This is the first replication association study of rs4325730 upstream of ICOS with AIH in the Japanese population and rs4325730G is a risk allele.

Abstract
Co-infection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) often accelerates the course of HCV-associated liver disease. Daclatasvir (DCV) plus asunaprevir (ASV) have been shown to be highly effective for HCV-infected patients with genotype 1b. Three patients co-infected with HIV/HCV genotype 1b were enrolled in this study. Prior to initiation of HCV treatment, the variants associated with L31 and Y93 in the non-structural protein 5A (NS5A) region of the HCV genome were confirmed to be absent using a direct sequencing method. Taking into consideration the lower risk of drug-drug interaction and the need for immediate treatment, the patients received 60 mg DCV once daily plus 100 mg ASV twice daily for 24 weeks. In one patient, the alanine aminotransferase level was elevated to 228 IU/L at 24 weeks after the start of treatment, but he completed the 24-week treatment course. All three patients achieved sustained viral response, without severe complications (including HIV virological rebound). Thus, in cases where NS5A variants are confirmed to be absent and patients are antiretroviral therapy-naïve, with CD4+ over 500/μL or HIV well controlled by RAL-based cART, DCV plus ASV may represent a good treatment option for HIV and HCV genotype 1b co-infected patients.

Abstract
BACKGROUND In this study, we demonstrated our new device for open donor liver surgery with left-sided heptectomy by use of the real-time moving windows (RTMW) method with 8-cm transverse skin incision for living donors from the viewpoints of cosmetic, economic, and safety procedures. METHODS After the upper abdominal 8-cm transverse skin incision was made, the subcutaneous area was exfoliated and the reverse T-shaped-abdominal incision was made, as in open surgery. After that, the 2 Kent hooks for the upper region and the 2 surgical arms for the lower region were placed. The operative fields of hepatic vein, hepatic hilus, and common hepatic artery were explored, respectively, by use of the RTMW method with the use of the 4 surgical hooks. Hepatic parenchymal dissection was carried out with the use of CUSA and laparosonic coagulating shears. Manipulations of 3 hepatic vessels and the hepatic duct were done by the usual procedure of open surgery. RESULTS This operative procedure could be performed without laparoscopic techniques. The operative time was 7 hours, without blood transfusion. The operative course was uneventful, and the patient was discharged on postoperative day 11. CONCLUSIONS Our RTMW method for donor left-sided hepatectomy is considered to be a useful operative procedure from the viewpoints of donor safety, cosmetic advantage, and cost performance.

Abstract
BACKGROUND To examine the effect of the histology of carcinoma and sarcoma components on survival outcome of uterine carcinosarcoma. PATIENTS AND METHODS A multicenter retrospective study was conducted to examine uterine carcinosarcoma cases that underwent primary surgical staging. Archived slides were examined and histologic patterns were grouped based on carcinoma (low-grade versus high-grade) and sarcoma (homologous versus heterologous) components, correlating to clinico-pathological demographics and outcomes. RESULTS Among 1192 cases identified, 906 cases were evaluated for histologic patterns (carcinoma/sarcoma) with high-grade/homologous (40.8%) being the most common type followed by high-grade/heterologous (30.9%), low-grade/homologous (18.0%), and low-grade/heterologous (10.3%). On multivariate analysis, high-grade/heterologous (5-year rate, 34.0%, P = 0.024) and high-grade/homologous (45.8%, P = 0.017) but not low-grade/heterologous (50.6%, P = 0.089) were independently associated with decreased progression-free survival (PFS) compared with low-grade/homologous (60.3%). In addition, older age, residual disease at surgery, large tumor, sarcoma dominance, deep myometrial invasion, lymphovascular space invasion, and advanced-stage disease were independently associated with decreased PFS (all, P < 0.01). Both postoperative chemotherapy (5-year rates, 48.6% versus 39.0%, P < 0.001) and radiotherapy (50.1% versus 44.1%, P = 0.007) were significantly associated with improved PFS in univariate analysis. However, on multivariate analysis, only postoperative chemotherapy remained an independent predictor for improved PFS [hazard ratio (HR) 0.34, 95% confidence interval (CI) 0.27-0.43, P < 0.001]. On univariate analysis, significant treatment benefits for PFS were seen with ifosfamide for low-grade carcinoma (82.0% versus 49.8%, P = 0.001), platinum for high-grade carcinoma (46.9% versus 32.4%, P = 0.034) and homologous sarcoma (53.1% versus 38.2%, P = 0.017), and anthracycline for heterologous sarcoma (66.2% versus 39.3%, P = 0.005). Conversely, platinum, taxane, and anthracycline for low-grade carcinoma, and anthracycline for homologous sarcoma had no effect on PFS compared with non-chemotherapy group (all, P > 0.05). On multivariate analysis, ifosfamide for low-grade/homologous (HR 0.21, 95% CI 0.07-0.63, P = 0.005), platinum for high-grade/homologous (HR 0.36, 95% CI 0.22-0.60, P < 0.001), and anthracycline for high-grade/heterologous (HR 0.30, 95% CI 0.14-0.62, P = 0.001) remained independent predictors for improved PFS. Analyses of 1096 metastatic sites showed that carcinoma components tended to spread lymphatically, while sarcoma components tended to spread loco-regionally (P < 0.001). CONCLUSION Characterization of histologic pattern provides valuable information in the management of uterine carcinosarcoma.

Abstract
BACKGROUND Previous genome-wide association studies have evaluated the impact of common genetic variants and identified several non-HLA risk loci associated with autoimmune liver diseases. More recent genome-wide association studies and replication analyses reported an association between variants of the CARD10 polymorphism rs6000782 and risk of type 1 autoimmune hepatitis (AIH). In this case-control study, we genotyped 326 Japanese AIH patients and 214 control subjects. RESULTS Genomic DNA from 540 individuals of Japanese origin, including 326 patients with type-1 AIH and 214 healthy controls, was analyzed for two single nucleotide polymorphisms (SNPs) in the CARD10 gene. We selected CARD10 rs6000782 SNPs and genotyped these using PCR-RFLP method and direct sequencing. The Chi square test revealed that the rs6000782 variant alle (c) was not associated with the susceptibility for AIH in a Japanese population [p = 0.376, odds ratio (OR) 1.271, 95 % confidence interval (CI) 0.747-2.161] in an allele model. Our data also showed that CARD10 rs6000782 variants were not associated with AIH or with the clinical parameters of AIH. CONCLUSIONS In this study we examined an association between rs6000782 SNPs in the CARD10 gene and type-1 AIH. Results showed no significant association of rs62000782 with type-1 AIH in a Japanese population. This study demonstrated no association between CARD10 rs6000782 variants and AIH in a Japanese population.

Abstract
We herein describe the case of a 42-year-old man who developed severe hepatitis caused by hepatitis C virus (HCV) infection at 14 years after the start of human immunodeficiency virus (HIV) treatment. Surprisingly, the levels of alanine aminotransferase (ALT) fluctuated, reaching a peak higher than 1,000 IU/L during chronic HCV infection, and the hepatic histology showed advanced liver fibrosis at 3 years after the primary HCV infection. He was treated with simeprevir, peginterferon-alpha, and ribavirin with a sustained viral response. We conclude that HCV/HIV co-infected patients need to commence anti-HCV therapy when the levels of ALT fluctuate severely under successful HIV control.

Abstract
The Mbita Health and Demographic Surveillance System (Mbita HDSS), located on the shores of Lake Victoria in Kenya, was established in 2006. The main objective of the HDSS is to provide a platform for population-based research on relationships between diseases and socio-economic and environmental factors, and for the evaluation of disease control interventions. The Mbita HDSS had a population of approximately 54 014 inhabitants from 11 576 households in June 2013. Regular data are collected using personal digital assistants (PDAs) every 3 months, which includes births, pregnancies, migration events and deaths. Coordinates are taken using geographical positioning system (GPS) units to map all dwelling units during data collection. Cause of death is inferred from verbal autopsy questionnaires. In addition, other health-related data such as vaccination status, socio-economic status, water sources, acute illness and bed net distribution are collected. The HDSS has also provided a platform for conducting various other research activities such as entomology studies, research on neglected tropical diseases, and environmental health projects which have benefited the organization as well as the HDSS community residents. Data collected are shared with the community members, health officials, local administration and other relevant organizations. Opportunities for collaboration and data sharing with the wider research community are available and those interested should contact shimadam@nagasaki-u.ac.jp or mhmdkarama@yahoo.com.

Abstract
This questionnaire survey was conducted at 11 hospitals in Japan to determine vaccination coverage against seasonal influenza and the prevalence rate of influenza among pregnant Japanese women. Of 2,808 postpartum women who gave birth at the 11 hospitals during the study period from March 1, 2014, to July 31, 2014, 1,713 (61 %) participated in this study and 876 (51 %) reported having received vaccination against influenza in or after October 2013. Women aged <25 years had a significantly lower vaccination rate than those aged ≥25 years (31 % vs. 53 %, respectively; p = 0.0000). Eighty-seven (5.1 %) and 1,626 (94.9 %) women did and did not contract influenza, respectively. Although prior birth did not affect overall vaccination coverage (50 % for primiparous vs. 53 % for multiparous), multiparous women had a significantly higher rate of contracting influenza than primiparous women, irrespective of vaccination status (5.6 % vs. 2.2 % [p = 0.0216] and 9.7 % vs. 3.5 % [p = 0.0003] for women with and without vaccination, respectively). The 2013-2014 vaccination program significantly reduced the influenza infection rate by 35 % (3.9 % vs. 6.3 % for women with and without vaccination, respectively; p = 0.0272). Seventy-two (83 %) of the 87 women took antiviral agents for the treatment of influenza and two (2.3 %) required hospitalization. These results suggested that pregnant Japanese women had a high level of concern regarding seasonal influenza. However, campaigns targeting young pregnant Japanese women, as well as multiparous women, for vaccination are needed in order to further reduce the incidence of influenza among pregnant Japanese women.

Abstract
Pathogens handled in a Biosafety Level 3 (BSL-3) containment laboratory pose significant risks to laboratory staff and the environment. It is therefore necessary to develop competency and proficiency among laboratory workers and to promote appropriate behavior and practices that enhance safety through biosafety training. Following the installation of our BSL-3 laboratory at the Center for Microbiology Research-Kenya Medical Research Institute in 2006, a biosafety training program was developed to provide training on BSL-3 safety practices and procedures. The training program was developed based on World Health Organization specifications, with adjustments to fit our research activities and biosafety needs. The program is composed of three phases, namely initial assessment, a training phase including theory and a practicum, and a final assessment. This article reports the content of our training program.

Abstract
Background An increasing risk of Schistosoma mansoni infection has been observed around Lake Victoria, western Kenya since the 1970s. Understanding local transmission dynamics of schistosomiasis is crucial in curtailing increased risk of infection. Methodology/Principal Findings We carried out a cross sectional study on a population of 310 children from eight primary schools. Overall, a total of 238 (76.8%) children were infected with S. mansoni, while seven (2.3%) had S. haematobium. The prevalence of hookworm, Trichuris trichiura and Ascaris lumbricoides were 6.1%, 5.2% and 2.3%, respectively. Plasmodium falciparum was the only malaria parasite detected (12.0%). High local population density within a 1 km radius around houses was identified as a major independent risk factor of S. mansoni infection. A spatial cluster of high infection risk was detected around the Mbita causeway following adjustment for population density and other potential risk factors. Conclusions/Significance Population density was shown to be a major factor fuelling schistosome infection while individual socio-economic factors appeared not to affect the infection risk. The high-risk cluster around the Mbita causeway may be explained by the construction of an artificial pathway that may cause increased numbers of S. mansoni host snails through obstruction of the waterway. This construction may have, therefore, a significant negative impact on the health of the local population, especially school-aged children who frequently come in contact with lake water. It is estimated that more than ten percent of the world's population is at risk of schistosome transmission, with over 90% of infections occurring in sub-Saharan Africa. In Kenya, schistosomiasis remains a major public health concern particularly around Lake Victoria. The objective of this study was to identify the risk factors associated with Schistosoma mansoni infection among schoolchildren on the shores and adjacent islands of Lake Victoria in Mbita district, western Kenya. High local population density was identified as an important risk factor for S. mansoni infection. Socio-economic factors were not found to be significantly associated with infection risk. Our study suggests that environmental changes related to causeway construction and the dense human population around Mbita town may result in favourable ecological conditions for S. mansoni transmission.

Abstract
Genetic variations in cytochrome P450 2C19 (CYP2C19) contribute to interindividual variability in the metabolism of therapeutic agents such as clopidogrel. Polymorphisms in CYP2C19 are associated with large interindividual variations in the therapeutic efficacy of clopidogrel. This study evaluated the in vitro oxidation of clopidogrel by 21 CYP2C19 variants harboring amino acid substitutions. These CYP2C19 variants were heterologously expressed in COS-7 cells, and the kinetic parameters of clopidogrel 2-oxidation were estimated. Among the 21 CYP2C19 variants, 12 (that is, CYP2C19.5A, CYP2C19.5B, CYP2C19.6, CYP2C19.8, CYP2C19.9, CYP2C19.10, CYP2C19.14, CYP2C19.16, CYP2C19.19, CYP2C19.22, CYP2C19.24 and CYP2C19.25) showed no or markedly low activity compared with the wild-type protein CYP2C19.1B. This comprehensive in vitro assessment provided insights into the specific metabolic activities of CYP2C19 proteins encoded by variant alleles, and this may to be valuable when interpreting the results of in vivo studies.

Abstract
Aberrant pancreas is used to describe ectopic pancreatic tissue lying outside its normal location with no anatomic or vascular connection to the pancreas proper. Patients with aberrant pancreas are usually asymptomatic, so aberrant pancreas are typically discovered incidentally during endoscopy, surgery, or autopsy. This time, we report a case of gastric aberrant pancreas bleeding was repeated and endoscopic hemostasis was difficult. A 22-year-old man was admitted to a hospital with a complaint of epigastric pain and melena. Upper gastrointestinal endoscopy and endoscopic ultrasonography (EUS) revealed a submucosal tumor with a bleeding ulcer at the anterior wall of the antrum in the stomach, and diagnosed it as an aberrant pancreas. It was hard to stop bleeding by in total 7 times endoscopic hemostasis and anemia was gradually progressed, so partial gastrectomy was performed. This gastric tumor measured 40 mm × 30 mm × 20 mm and had a severe ulcerative change. The pathological diagnosis was aberrant pancreas with Langerhans islet, acinous cells and excretory duct. (Heinrich type) Until December 2013 in Japan, 13 cases of gastric aberrant pancreas with bleeding have been reported and in these, a surgery was done in 11 cases. In gastric aberrant pancreas cases with ulcer formation like this case, endoscopic hemostasis is expected to be difficult, and surgery is necessary. Hence, early accurate diagnosis by EUS is a very important to decide better treatment plan.

Abstract
INTRODUCTION We report a case of low-risk stomach gastrointestinal stromal tumor (GIST) which has been under a long-term observation, obtaining from this experience knowledge useful in determining the treatment formula for this disease. RESULTS During the observation for 6 years, no such change as ulcer formation was observed in the appearance of the tumor. The measurement of tumor diameter, however, showed gradual growth of maximum tumor diameter from 2.7 to 5.0 cm. When the changes in the diameter of tumor during this period is plotted, taking the timeon the horizontal axis and the tumor diameter on the vertical axis, the growth of the tumor can be approximated with a secondary function, making it possible to estimate the developmental period of the GIST concerned from the approximated secondary function. Thus, the developmental period in this case was estimated to go back 19 years before the time when it was discovered for the 1(st) time. Further, it was considered that the coefficient of the secondary function represents the rate of tumor growth, and that comparison with this coefficient contributed to the evaluation of malignancy stage of the GIST concerned. CONCLUSION The growth curve predicting the growth of tumor could be depicted by measuring the diameter of the tumor in GIST twice or more at an interval of 6-12 months with EUS, and it was thought that this was utilizable for determining treatment formula for GISTs.

Abstract
Crude rates such as the crude death rate are functions of both the age-specific rates and the age composition of a population. However, differences in the age structure between two populations or two time periods can result in specious differences in the corresponding crude rates making direct comparisons between populations or across time inappropriate. Therefore, when comparing crude rates between populations, it is desirable to eliminate or minimize the influence of age composition. This task is accomplished by using a standard age structure yielding an age-standardized rate. This paper proposes an updated International Network for the Demographic Evaluation of Populations and Their Health (INDEPTH) standard for use in low- and middle-income countries (LMICs) based on newly available data from the health and demographic surveillance system site members of the INDEPTH network located throughout Africa and southern Asia. The updated INDEPTH standard should better reflect the age structure of LMICs and result in more accurate health indicators and demographic rates. We demonstrate use of the new INDEPTH standard along with several existing ‘world’ standards and show how resulting age-standardized crude deaths rates differ when using the various standard age compositions.
