Abstract
Enzootic bovine leukosis (EBL) is typically observed in cattle older than 3 years, but some cases of onset in cattle younger than 3 years have been reported in Japan. BoLA-DRB3 polymorphisms are associated with susceptibility to EBL onset. However, little is known about the relationship between the polymorphisms and EBL onset in young cattle. In the present study, we performed BoLA-DRB3 genotyping in 59 EBL cattle younger than 3 years (25 Holstein-Friesian and 34 Japanese Black) and compared the results with those of 69 EBL cattle older than 3 years (38 Holstein-Friesian and 31 Japanese Black). The BoLA-DRB3*15:01 allele was detected at a frequency of 37.3 % (48.0 % and 29.4 % in Holstein-Friesian and Japanese Black, respectively) and was identified as an early EBL onset susceptibility allele. Nine EBL cattle younger than 3 years (5 Holstein-Friesian and 4 Japanese Black), but only 1 EBL cattle older than 3 years (1 Holstein-Friesian), had a BoLA-DRB3*15:01/*15:01 homozygous genotype. The frequency of the BoLA-DRB3*15:01 allele occurring with a different allele (BoLA-DRB3*015:01/other) in cattle younger than 3 years was 44.1 % (56.0 % Holstein-Friesian and 35.3 % Japanese Black) and significantly higher than that in cattle older than 3 years (28.9 % Holstein-Friesian and 9.7 % Japanese Black) (P = 0.0013). These results suggest that BoLA-DRB3*15:01/*15:01 and BoLA-DRB3*15:01/other genotypes are early EBL onset susceptibility genotypes. The present findings may contribute to cattle breeding selection.

Abstract
In recurrent or metastatic head and neck squamous cell carcinoma (R/M-HNSCC), survival outcomes are significantly better in patients who receive anti-programmed cell death-1 (PD-1) monoclonal antibody therapy than in those who receive standard therapy. However, there is no established biomarker that can predict the anti-PD-1 antibody treatment effect and immune-related adverse events (irAEs) in these patients. This study investigated the inflammatory and nutritional status in 42 patients with R/M-HNSCC and programmed cell death ligand-1 (PD-L1) polymorphisms (rs4143815 and rs2282055) in 35 of the 42 patients. The 1- and 2-year overall survival was 59.5% and 28.6%, respectively; the 1- and 2-year first progression-free survival was 19.0% and 9.5%, respectively, and the respective second progression-free survival was 50% and 27.8%. Performance status and inflammatory and nutritional status (assessed by the geriatric nutritional risk index, modified Glasgow prognostic score, and prognostic nutritional index) were identified as significant indicators of survival outcomes in multivariate analysis. Patients with ancestral alleles in PD-L1 polymorphisms had less frequent irAEs. Performance status and inflammatory and nutritional status before treatment were closely related to survival outcomes after PD-1 therapy. These indicators can be calculated using routine laboratory data. PD-L1 polymorphisms may be biomarkers for predicting irAEs in patients receiving anti-PD-1 therapy.

Abstract
This study aimed to clarify the roles of high-risk human papillomavirus (HR-HPV) infection and epidermal growth factor receptor (EGFR) exon 20 mutations in sinonasal inverted papilloma (IP) and sinonasal squamous cell carcinoma (SNSCC). Samples were collected from 20 cases with IP, 7 with IP and squamous cell carcinoma (IP-SCC), and 20 with SNSCC and examined for HPV infection and EGFR exon 20 mutations. Low- or high-risk HPV DNA was observed in 25% of IP, 57.1% of IP-SCC, and 35% of SNSCC cases. Transcriptionally active HR-HPV infections in IP-SCC and SNSCC, accompanied by p16 overexpression, were observed in 28.5% and 25% of cases, respectively. Heterozygous EGFR exon 20 amino acid insertions (ex20ins), located between amino acids 768-774, were observed in 45% of IP, 28.5% of IP-SCC, and 0% of SNSCC and chronic sinusitis cases. EGFR phosphorylation sites were located at tyrosine (Y) 845, Y1068, Y1086, and Y1197 and induced PI3K/AKT/mTOR activation. The phosphorylation pattern of EGFR with ex20ins resembled that of HPV-related SNSCC and oropharyngeal cancer. The transcriptionally active HR-HPV infection and ex20ins might be responsible for the pathogenesis of IP-SCC cases with different fashions. Since IP-SCC might be a multifactorial disease, further investigation is needed to understand IP-SCC etiology.

Abstract
BACKGROUND Peer support among family members is important in cases of mental illness, but there has been limited practice or research on individual peer support specific to families taking care of patients with eating disorders (EDs). To conduct peer support activities, it is necessary to clarify the needs of families. OBJECTIVES The objective of this study are to identify the needs for group and individual peer support and the characteristics of family members with EDs who are willing to receive and provide individual peer support. METHOD A cross-sectional questionnaire survey was conducted for family members with EDs recruited via the Internet. The questionnaires included demographic information on respondents and their patients, questions about the need for family peer support, interest in offering peer support, and social resources. All participants were given the General Health Questionnaire (GHQ-12), the Zarit Caregiver Burden Interview (J-ZBI_8), and the Anorectic Behavior Observation Scale (ABOS). RESULTS Out of 314 respondents, 87.3% believed that a group peer support system was necessary, whereas 56.7% believed that an individual peer support system was necessary. As to whether they want to use individual peer support, 70 (22.4%) stated "Extremely YES" and 99 (31.7%) stated "Moderately YES." Family members who were willing to receive individual peer support used more social resources and had higher scores on the GHQ and J-ZBI_8. Regarding the provision of peer support, 38 (12.2%) responded "very interested and willing to provide it if possible" and 87 (27.9%) responded "interested and willing to study." Those with a high willingness to provide peer support used more social resources and had lower ABOS scores; however, 38 respondents (45.7%) exceeded the GHQ mental health screening cutoff (3/4). CONCLUSION Family members with ED had a strong need for family peer support Those willing to receive individual peer support suffered from poor mental health and high burden of care. Family members willing to provide peer support tended to have patients whose EDs symptoms had already improved, but their own mental health was not necessarily good. Training for potential peer supporters is needed to implement peer support.

Abstract
Enzootic bovine leukosis (EBL) is one of bovine neoplasms caused by bovine leukemia virus (BLV). Although EBL is typically observed in cattle over 3 years old, several cases of EBL onset in cattle under 3 years old have been reported in Japan. The mechanism for EBL onset in young cattle remains unclear. Although genetic variation of BLV is limited, the variations could affect viral properties relating to BLV pathogenesis. The purpose of this study was to clarify relationship between early onset of EBL and BLV groups. Moreover, we also aimed to characterize BLV that cause early onset of EBL. Whole genome sequences of BLV in 72 EBL cattle under 3 years old and 50 EBL cattle over 3 years old were identified. Phylogenetic analysis showed that BLV was divided into 4 groups (A, B-1, B-2 and Other). The BLV from EBL cattle under 3 years old were mainly classified as group A and B-1, while those from EBL cattle over 3 years old were mainly included in group B-2. Common sequence of group A and B-1 was compared with those of group B-2. Specific sequences in LTRs, gag-pro-pol, env and tax gene regions were identified in these groups. Amino acid substitutions of Pro and Tax protein were predicted in those nucleotide sequences. Those genetic variations might contribute to the early onset of EBL.

Abstract
BACKGROUND The prolonged pandemic of coronavirus disease 2019 (COVID-19) has resulted in mental burden among healthcare workers (HCWs). This study aimed to conduct a repeated study to assess changes in psychological concerns among Japanese HCWs. METHODS This study is the second survey involving HCWs at the Japanese Red Cross Medical Center conducted between November 20, 2020 and December 4, 2020. The degree of symptoms of anxiety, depression, and resilience was assessed using the Japanese versions of the 7-item Generalized Anxiety Disorder Scale, Center for Epidemiologic Studies Depression Scale, and 10-item Connor-Davidson Resilience Scale, respectively. RESULTS The survey included 594 HCWs, comprising 95 physicians, 261 nurses, 150 other co-medical staff, and 88 office workers. Among them, 46 (7.7%) and 152 (25.6%) developed moderate-to-severe symptoms of anxiety and depression, respectively. Compared with those in the initial survey conducted 6 months earlier, the resilience score did not change, whereas the anxiety and depression scores improved significantly (P < 0.001, P = 0.033, respectively). However, the frequency of HCWs developing moderate-to-severe symptoms of anxiety or depression did not significantly improve. Multivariable logistic regression analysis showed that having higher anxiety symptoms was a risk factor for depression symptoms, while older HCWs and those with higher resilience were less likely to develop depression symptoms. CONCLUSIONS Many HCWs still suffer from psychological concerns during the COVID-19 pandemic.

Abstract
A 21-mo-old Japanese Black beef cow had swollen mandibular and superficial cervical lymph nodes. Fine-needle aspiration cytology of the superficial cervical lymph node revealed large lymphoblasts with mitoses present. The bovine leukemia virus (BLV) proviral load was relatively high, and phylogenetic analysis of the whole BLV genome classified the BLV strain as one with high viral replication activity. Genotyping of bovine leukocyte antigen genes indicated that the cow was susceptible to enzootic bovine leukosis (EBL). The bone morphogenetic protein 6 (BMP6) gene promoter region was hypermethylated. Monoclonal proliferation of B cells and monoclonal integration of the BLV provirus in the bovine genome were detected by a clonality test of B cells and an inverse PCR assay, respectively. At autopsy, generalized swelling of lymph nodes and spinal canal invasion by tumor tissue at vertebrae L5-6 were observed. Histologic analysis revealed diffuse proliferation of large round neoplastic cells that were positive for BLA36 and negative for CD3. The cow was definitively diagnosed with EBL based on these findings. Infection with a highly pathogenic strain of BLV, susceptibility of the BoLA-DRB3 alleles, and hypermethylation of the BMP6 gene may have contributed to the development of EBL in our case.

Abstract
We aimed to evaluate the pharmacokinetics and pharmacological effects of glimepiride in the Spontaneously Diabetic Torii (SDT) rat, which is a non-obese model of type 2 diabetes. After oral administration of glimepiride (10 mg/kg), the maximum plasma concentrations and the area under the curve from 0 to 6 h of glimepiride in SDT rats were significantly higher than those in age-matched Sprague-Dawley rats. Whereas, additional insulin secretion following glimepiride treatment was markedly reduced in SDT rats. Thus, the SDT rat can be regarded as a model that reflects type 2 diabetes with reduced insulin secretory capacity. Our findings suggested that glimepiride could be ineffective in sever type 2 diabetic patients.

Abstract
Peripheral B-lymphocyte clonality of 274 bovine leukemia virus-infected cattle with
lymphocytosis was analyzed using clonality PCR based on sequences of the variable region
of the bovine immunoglobulin H chain. None of the cattle showed monoclonal proliferation,
while 10, 31, and 233 showed minor-clonal, oligoclonal, and polyclonal proliferation,
respectively. A total of 163 cattle were analyzable the following year, and lymphocytosis
was maintained in 157, indicating persistent lymphocytosis (PL). B-lymphocyte clonality of
the 157 PL cattle was minor-clonal in 6 (3.8%), oligoclonal in 8 (5.1%), and polyclonal in
143 (91.1%). A higher rate of enzootic bovine leukosis (EBL) onset within a year was
observed in PL cattle with minor-clonal (50.0% (3/6)) and oligoclonal (25.0% (2/8))
proliferation compared to those with polyclonal (5.6% (8/143)) proliferation. Minor-clonal
and oligoclonal proliferation in PL cattle may be a prognosis factor for developing
EBL.

Abstract
BACKGROUND Medical tourism has grown globally, especially in oncology field, but it may cause serious problems. We aimed to elucidate concerns generated by medical tourism at a Japanese hospital and recommend solutions. METHODS We evaluated 72 consecutive patients with cancer who had traveled from abroad to receive second opinions, clinical examinations or treatments at our hospital between January 2015 and December 2016. Data were retrospectively collected to include the purpose of patients' visits, presence and content of referral documents, details of treatments provided at our hospital, concordance between treatments received and patients' expectations, troublesome hospital incidents, risks of travel and problems with payment. RESULTS The purpose of the visit was actual cancer treatment in the majority of the cases. Thirteen patients could speak neither Japanese nor English. Inadequate content in patient referral documents and discordance between information from the referring physician and findings at first examination were the main issues observed in the pre-treatment phase; 33 patients decided to receive treatment at our hospital. Language differences caused problems in patients' understanding of instructions and explanations during treatment. Additional problems included inaccurate self-evaluation of disease status, differences in cultural habits and requests for inappropriate and/or unavailable therapies. No major issues that could lead to injury in patients or medical staff were observed. Risks involved with returning home and transfer of treatment to local physicians were the main post-treatment issues. CONCLUSION Medical tourism raises various issues. Institutional and medical staff should be adequately prepared by developing working systems.

Abstract
Objective Coronavirus disease 2019 (COVID-19) is spreading around the world. The aim of this study was to assess the degree of anxiety, depression, resilience, and other psychiatric symptoms among healthcare workers in Japan during the COVID-19 pandemic. Methods This survey involved medical healthcare workers at the Japanese Red Cross Medical Center (Tokyo, Japan) between April 22 and May 15, 2020. The degree of symptoms of anxiety, depression, and resilience was assessed using the Japanese versions of the 7-item Generalized Anxiety Disorder Scale (GAD-7), Center for Epidemiologic Studies Depression Scale (CES-D), and 10-item Connor-Davidson Resilience Scale. Furthermore, we added original questionnaires comprising three factors: (i) anxiety and fear of infection and death; (ii) isolation and unreasonable treatment; and (iii) motivation and escape behavior at work. Results In total, 848 healthcare workers participated in this survey: 104 doctors, 461 nurses, 184 other co-medical staff, and 99 office workers. Among all participants, 85 (10.0%) developed moderate-to-severe anxiety disorder, and 237 (27.9%) developed depression. Problems with anxiety and fear of infection and death, isolation and unreasonable treatment, and motivation and escape from work were higher in the depression group than in the non-depression group (total CES-D score ≥ 16 points). Being a nurse and high total GAD-7 scores were risk factors of depression. Older workers and those with higher resilience were less likely to develop depression than others. Conclusion During the COVID-19 epidemic, many healthcare workers suffered from psychiatric symptoms. Psychological support and interventions for protecting the mental health of them are needed.

Abstract
INTRODUCTION The concept of the glenoid track has been proposed to evaluate the risk of dislocation. The glenoid track width was demonstrated to be 84% of the glenoid width in cadaveric shoulders and 83% in live shoulders. HYPOTHESIS The glenoid track width seems to be affected by the range of motion. PURPOSE The purpose of this study was to determine the relationship between the glenoid track and the range of shoulder motion. METHODS Ten fresh-frozen cadaveric shoulders were used. The specimen was fixed to a shoulder-positioning device. The anterior rim of the glenoid was marked on the humeral head using a Kirschner wire with the arm in 60° of abduction. This marking was repeated with the arm in (1) horizontal flexion/extension and (2) internal/external rotations (0° to max). The distances from the Kirschner wire markings to the footprint of the rotator cuff tendon were measured. RESULTS The greater the angle of the horizontal extension or external rotation, the smaller the glenoid track width, whereas the greater the angle of the horizontal flexion or internal rotation, the greater the glenoid track width. There was a negative relationship between them. The horizontal flexion/extension motion was demonstrated to affect the glenoid track width more than the internal/external rotation motion. CONCLUSION The glenoid track width decreased with the increase of horizontal extension. We should consider the range of horizontal extension angle when applying the glenoid track concept in clinical practice. TYPE OF STUDY Laboratory study.

Abstract
WHAT IS KNOWN AND OBJECTIVE Glucocorticoid-induced diabetes mellitus (GIDM) increases the risk of diabetes mellitus (DM)-related complications but is generally difficult to detect in clinical settings. The criteria for diagnosing GIDM have not been established. Recently, medical information databases (MIDs) have been used in post-marketing surveillance (PMS) studies. We conducted a pharmacoepidemiological study to develop an algorithm for detecting GIDM using MID. METHODS We selected 1214 inpatients who were newly prescribed with a typical glucocorticoid, prednisolone, during hospitalization from 2008 to 2014 from an MID of Hamamatsu University Hospital in Japan. GIDM was screened based on fasting blood glucose (FBG) and haemoglobin A1c (HbA1c) levels according to the current Japan Diabetes Society (JDS) DM criteria, and its predictability was evaluated by an expert's review of medical records. We investigated further candidate screening factors using receiver operating characteristics analysis. RESULTS Sixty-three inpatients were identified by the JDS DM criteria. Of these, 33 patients were definitely diagnosed as having GIDM by expert's review (positive predictive value = 52·4%). To develop a highly predictive algorithm, we compared the characteristics of inpatients diagnosed with definite GIDM and those diagnosed as non-GIDM. The maximum levels of HbA1c in patients with GIDM were significantly higher than those of patients with non-GIDM (66·9 mmol/mol vs. 58·7 mmol/mol, P < 0·001). The patients with GIDM had significantly higher relative increase in maximum level of HbA1c (RIM-HbA1c) than those with non-GIDM (0·3 vs. 0·03, P < 0·001). However, we did not observe a significant difference in those of fasting blood glucose (FBG) levels. We applied the RIM-HbA1c as a second screening factor to improve the detection of GIDM. It showed that a 13% increase in RIM-HbA1c separated patients with from patients without GIDM. WHAT IS NEW AND CONCLUSIONS Patients with GIDM had significantly higher RIM-HbA1c than patients with non-GIDM. There was a 13% increase in RIM-HbA1c in patients with GIDM compared to the others. Our detection algorithm for GIDM using an MID achieved high sensitivity and specificity, and was superior to one based only on the current JDS DM criteria. Our results suggest that monitoring changes in HbA1c levels is important for detecting GIDM and adds to current diagnostic criteria for type 2 DM.

Abstract
Molecularly targeted anticancer agents cause a variety of adverse reactions compared with conventional anticancer agents because of their unique mechanisms of action. Sources of drug information such as package inserts (PIs) provide primarily document-based and numerical information. Therefore it is not easy to obtain a complete picture of drugs with similar effects, or to understand differences among drugs. In this study we used the self-organizing map (SOM) technique to visualize the adverse reactions indicated on PIs of 23 molecularly targeted anticancer agents as of March 2013. In both the presence/absence version and the frequency version, SOM was divided into domains according to mechanism of action, antibody drug or low-molecular weight drug, and molecular target. The component planes of the 753 adverse reaction items in the frequency version enabled us to grasp all available information and differences among the drugs. In some component planes in the presence/absence version, an adverse reaction that had not been reported for a drug but had already been reported for its proximally positioned drug(s) as of March 2013, was found to be reported thereafter by the Drug Safety Update (DSU) or the Adverse Event Report Search System "CzeekV," which is based on FDA Adverse Event Reporting System (FAERS). Our results suggest that visualization of the adverse reactions of molecularly targeted anticancer agents by the SOM technique is useful not only to acquire all available information and differences among drugs, but also to predict the appearance of adverse reactions.

Abstract
BACKGROUND Accurate information about patients' use of medication is crucially important for medical treatment. Real-time information can prevent treatment failure resulting from medication delays or failures. OBJECTIVE In this study, a compliance-monitoring system is developed for physicians to ascertain their patients' drug-taking behaviors at home in real time. Its operation is then evaluated. METHODS The authors produced a device that uses wireless communication to notify a physician that drugs are taken out of a package by a patient. The device has sensors to detect the package opening. A wireless module is installed in a drug-containing calendar-type pill organizer. RESULTS Experimental trials confirmed that a physician can monitor the kind and number of drugs removed from the package on a real-time basis. Furthermore, a practical system can be produced by measuring the distance and consumption current of the produced device, which allows wireless communication. CONCLUSIONS This system enables a doctor to intervene immediately when any compliance lapse occurs, thereby preventing treatment failure caused by delayed response.

Abstract
We developed a compliance monitoring system that electrically detects which drug among the multiple prescribed drugs a patient has taken and the date of drug-taking by a patient to prevent the patient from missing doses and taking drugs incorrectly at home. A conductive pattern is screen printed using conductive ink (silver paste) on the surface of a calendar-type pill organizer containing medications for as long as 1 week (4 times per day × 7 days, 28 doses) to create a sensor for detecting the opening of a pill organizer. Whenever the patient opens the pill organizer and removes a dose of the drug (pill), information about which of the 28 locations is opened and the date of opening are recorded in nonvolatile memory. This system is applicable to patients who take multiple drugs, for whom recording of drug-taking behavior is reportedly difficult. Specific benefits are that the user needs no additional manipulation to use the system: the user can take the drug from the pill organizer according to usual procedures.

Abstract
Outer mitochondrial membrane (OMM) rupture was first noted in isolated mitochondria in which the inner mitochondrial membrane (IMM) had lost its selective permeability. This phenomenon referred to as mitochondrial permeability transition (MPT) refers to a permeabilized inner membrane that originates a large swelling in the mitochondrial matrix, which distends the outer membrane until it ruptures. Here, we have expanded previous electron microscopic observations that in apoptotic cells, OMM rupture is not caused by a membrane stretching promoted by a markedly swollen matrix. It is shown that the widths of the ruptured regions of the OMM vary from 6 to 250 nm. Independent of the perforation size, herniation of the mitochondrial matrix appeared to have resulted in pushing the IMM through the perforation. A large, long focal herniation of the mitochondrial matrix, covered with the IMM, was associated with a rupture of the OMM that was as small as 6 nm. Contextually, the collapse of the selective permeability of the IMM may precede or follow the release of the mitochondrial proteins of the intermembrane space into the cytoplasm. When the MPT is a late event, exit of the intermembrane space proteins to the cytoplasm is unimpeded and occurs through channels that transverse the outer membrane, because so far, the inner membrane is impermeable. No channel within the outer membrane can expose to the cytoplasm a permeable inner membrane, because it would serve as a conduit for local herniation of the mitochondrial matrix.

Abstract
In our previous papers we proposed a novel screening method that assists the diagnosis of patients with overt Graves' hyperthyroidism by making use of routine test data and pattern recognition methods. This method can be applied by non-specialists during physical check-ups at low cost and is expected to lead to rapid referrals for examination and treatment by thyroid specialists, that is, to improve patients' QOL. In this report, we investigate whether a similar screening method is also applicable for overt hypothyroidism. Fifty-six subjects with 12 routine test data with a known diagnosis (30 patients with overt hypothyroidism and 52 healthy female volunteers, and 26 patients with overt hypothyroidism and 48 healthy male volunteers) were used as training data. Then, test samples of patients who had also undergone the same routine tests at the Tohoku university hospital were screened by our method for overt hypothyroidism. The present examination of the screening method showed its high screening ability with the set of four parameters used (lactate dehydrogenase [LDH], total cholesterol [TC], red blood cell [RBC] and serum creatinine [S-Cr]). It was found that there was a strong multiple correlation between the set of routine test parameters and serum total thyroxine (TT4) in the patients with overt hypothyroidism, which supports the usefulness of our screening method.

Abstract
WHAT IS KNOWN AND OBJECTIVE The factors affecting the pharmacokinetics of free mycophenolic acid (MPA) and its phenolic glucuronide (MPAG) are still unclear. The aim of this study was to evaluate the influence of cyclosporine on the pharmacokinetics of free MPA and MPAG. METHODS Seventy-seven kidney transplant recipients (23 were in an initial phase and 54 in a stable phase; 41 were treated with cyclosporine and 36 with tacrolimus) were enrolled. Free and total MPA and MPAG were determined using HPLC. The correlations between free and total predose concentrations (C(0) ) of MPA or MPAG were evaluated separately in patients receiving calcineurin inhibitor medications. RESULTS AND DISCUSSION Serum concentration of albumin was lower in the initial phase than in the stable phase. A higher ratio of free MPAG C(0) to free MPA C(0) was observed in cyclosporine-treated than tacrolimus-treated kidney transplant recipients. Free MPA C(0) correlated weakly with total MPA C(0) in kidney transplant recipients treated with cyclosporine in the initial phase (ρ= 0·53, P = 0·06). WHAT IS NEW AND CONCLUSION Cyclosporine increased the ratio of free MPAG C(0) to free MPA C(0) and varied the free fraction of MPA in the hypoalbuminaemic kidney transplant recipients in the initial phase.

Abstract
In our previous paper, we proposed a novel screening method that aids the diagnosis of female patients with Graves' hyperthyroidism via two types of neural networks and the use of routine test data. This method can be applied by non-specialists during physical checkups at a low cost and is expected to lead to rapid referrals for examination and treatment by thyroid specialists; i.e., to improve patients' QOL. In this report, we investigate whether the screening method is also applicable to males since sex differences exist in routine test data. The values of 14 routine test parameters for 78 subjects with definite diagnoses (31 patients with Graves' hyperthyroidism and 48 healthy volunteers) were adopted as training data, and 133 individuals who had also undergone the same routine tests at Tohoku University Hospital were screened for Graves' hyperthyroidism using our method. The present examination of our screening method in males showed its high screening ability with the set of parameters used (low serum creatinine, elevated alkaline phosphatase, and low total cholesterol). It was also found that there is strong multiple correlation between a set of three parameters and serum free thyroxine (FT4) in male patients with Graves' hyperthyroidism. A formula for FT4 consisting of three parameters was obtained, and this can be utilized in place of the true FT4 value. This result also supports the usefulness of our screening method.

Abstract
OBJECTIVE We aimed to investigate recent trends in prescriptions for the treatment of paediatric gastroenteritis in Japan over a 10-year period (1997-2007). METHODS In this retrospective cohort study, we collected data for 2295 prescriptions for 1241 putative cases of paediatric gastroenteritis, which were treated between 1997 and 2007 at Hamamatsu University Hospital, Hamamatsu, Japan. RESULTS The most frequently prescribed drugs were probiotics (n = 621), followed by anti-emetics (n = 474). In most years between 1997 and 2007, more cases were treated with probiotics than with any other drug type (30.6-63.3% of cases), with the percentage increasing between 2005 and 2007. In contrast, the frequencies of anti-emetic and antipyretic prescriptions remained fairly stable, and prescriptions for antibiotics decreased slightly over the study period. Anti-emetics were commonly used in this hospital. CONCLUSION Although experimental evidence upon which to base recommendations is lacking, Japanese evidence-based guidelines are critical for improving the quality of treatment of paediatric gastroenteritis.

Abstract
Avian infectious bronchitis viruses (IBVs) isolated from commercial layer flocks kept in Ibaraki Prefecture in 2009 were genetically and serologically characterized. Reverse transcription-PCR coupled with direct nucleotide sequencing and GenBank BLAST database analysis of the hypervariable region of the S1 subunit of the virus spike gene showed that these isolates are genetically very different from the previously known IBV genotypes in Japan. Furthermore, none of the antisera used in this study neutralized the index isolate (JP/Ibaraki/168-1/2009) in virus neutralization tests. These results suggest that the isolates are a novel IBV genotype in Japan (designated JP-IV).

Abstract
Synthesis and properties of an oligonucleotide uniformly modified with 2'-O,4-C-ethylene-bridged nucleic acid (ENA) units were compared with those of GRN163, which is modified with N3'-P5' thiophosphoramidates, with the sequence targeting human telomerase RNA subunit. Although an ENA phosphorothioate oligonucleotide, ENA-13, could be synthesized using ENA phosphoramidites on a 100-mg scale, synthesis of GRN163 was very hard even on a 1-micomol scale. In view of both stability of the duplex formation with complementary RNA and the efficiency of cellular uptake by endocytosis, ENA-13 was superior to GRN163. These findings suggest that ENA-13 has useful properties for antisense therapeutic application.

Abstract
Oligonucleotides uniformly modified with 2'-O,4'-C-ethylene-bridged nucleic acid (ENA) units were synthesized using the phosphoramidite method on a hundred-milligram scale for the evaluation of thermodynamic and chemical properties. The properties of these ENA oligonucleotides with the sequences targeted to human telomerase RNA subunit (hTR) were compared with those of GRN163, which is an oligonucleotide modified with N3'-P5' thiophosphoramidates. The melting temperatures of the duplexes of ENA oligonucleotides with complementary RNA were higher than that of the duplex of GRN163. Moreover, ENA oligonucleotide ENA-13 was more highly stable than GRN163 under acidic conditions (pH 5.0). ENA-13, which contained contiguous guanine sequences, could not form a G-quadruplex, which formation is not feasible for binding to hTR as an antisense molecule. The above findings suggest that ENA oligonucleotides may be useful for antisense therapeutic applications.

Abstract
This study assessed the relationship between craniofacial characteristics and the size of the pharyngeal airway space (PAS), taking into account head posture. Sixty dental students 25-30 years of age (30 men and 30 women) were examined by lateral cephalometry. The data were corrected with the use of appropriate regression equations for the PAS. The PAS significantly correlated with hyoid position, maxillary and mandibular size, maxillary and mandibular prognathism, and mandibular inclination. A large, anteriorly positioned mandible was associated with a large PAS-TP (the most proximal distance between the posterior pharyngeal wall and the tongue base). Uvula length and PNS-Ba (the distance between the most posterior point of the hard palate and the most inferior point of the anterior foramen magnum) correlated with PAS-UP (the most proximal distance between the posterior pharyngeal wall and uvula). Our results suggest that the anteroposterior dimension of the PAS is substantially affected by the size of the enclosure surrounding the PAS, including the maxilla, mandible and soft palate.

Abstract
Patients with hyperthyroidism sometimes take much time to receive the final diagnosis. To improve patient QOL, simple screening for hyperthyroidism by thyroid non-specialists at the physical check-up is highly expected. Therefore, we applied both Bayesian-type and SOM-type neural networks since we assured the approach useful in analysing thyroid function diagnosis in the previous work. Routine test (14 parameters) data from 66 subjects with a known diagnosis (18 patients with hyperthyroidism and 48 healthy volunteers) were adopted as learning data, and then 142 individuals who also received the same routine tests at the Tohoku University Hospital were screened to predict patients with hyperthyroidism. Both neural networks using 14 parameters predicted several patients as having hyperthyroidism with high probability, including all three hyperthyroid patients diagnosed later by the physician. Further detailed analysis of the routine test parameters that were important for classification found that screening with a set of three parameters (alkaline phosphatase, serum creatinine and total cholesterol) or plus aspartate aminotransferase allowed for quite accurate screening. These results showed that the same neural networks as previous work allows simple screening of patients for hyperthyroidism on the basis of routine test data, and that physicians not specializing in the thyroid can rapidly identify individuals suspected of having hyperthyroidism, to permit a rapid referral for examination and treatment by thyroid specialists.

Abstract
The aim of this study was to investigate the position and course of the mandibular canal through the mandibular ramus using computed tomographic (CT) imaging and to relate the findings to performing sagittal split ramus osteotomies. The mandibles of 35 patients with skeletal Class III prognathism with symmetry (12 males and 23 females) were observed on transaxial computed tomograms acquired with a slice thickness of 2 mm. The position and course of the mandibular canal from the mandibular foramen to the mandibular body at the level of the second molar were measured at four specific locations in the same plane. Among the 70 rami examined, lack of a bone marrow space on the buccal side, including a fusion type anatomy with no buccal side cortical bone of the mandibular canal, were observed at the CT location between the mandibular foramen and mandibular angle. Our results suggest that special care must be taken when sagittal splitting is performed, and the safest location for the buccal corticotomy is anterior to the mandibular angle.
