The Promotion of Social Inclusion by Adopting of the Private Finance Initiative on a Correctional Institution

This study focuses on two questionnaire surveys that were conducted about the adoption of the Private Finance Initiative (PFI prison) method in Japan as a new correctional system. For study 1, a Web questionnaire was administered to residents of within a 30 km zone of Tokyo as well as those in Yamaguchi Prefecture to determine familiarity and resistance to the PFI prison systems. For study 2, a questionnaire survey was administered to residents of a neighborhood near a PFI prison in Mine city. The results showed that the attitudes toward the PFI prison were more positive in this area. Furthermore, contact with the correctional systems promoted residents’ acceptance of prisoners and former prisoners. Finally, we discuss social and institutional support and contact with social systems to promote social inclusion

Novel Variants in the CLCN1, RYR2, and DCTN1 Found in Elderly Japanese Dementia Patients: A Case Series

Dementia has an enormous impact on medical and financial resources in aging societies like Japan. Diagnosis of dementia can be made by physical and mental examinations, imaging tests, and findings of high abnormal proteins in cerebrospinal fluids. In addition, genetic tests can be performed in neurodegenerative diseases such as Alzheimer's disease (AD), frontotemporal dementia (FTD), and Parkinson's disease (PD). In this case series, we presented three cases of dementia with unknown causes who carry novel variants in the genes associated with neurodegenerative diseases. Three patients (Patients 1, 2, and 6) were found by screening 18 dementia patients using a gene panel including 63 genes. The age of onset for Patient 1 was 74 years old, and his father had PD and mother had AD. The age of onset for Patient 2 was 75 years old, and her mother had AD. The age of onset for Patient 6 was 83 years old, and her father, two sisters, and daughter had dementia. The Mini-Mental State Examination produced results of 20, 15, and 22, respectively. The suspected diagnosis by neurological examinations and imaging studies for Patients 1 and 2 was AD, and for Patient 6 was FTD. Patient 1 was treated with donepezil; Patient 2 was treated with donepezil and memantine; and Patient 6 was treated with donepezil, galantamine, and rivastigmine. The three rare variants identified were: CLCN1, encoding a chloride channel, c.2848G>A:p.Glu950Lys (Patient 1); RYR2, encoding a calcium releasing ryanodine receptor, c.13175A>G:p.Lys4392Arg (Patient 2); and DCTN1, encoding a subunit of dynactin, c. 3209G>A:p.Arg1070Gln (Patient 6). The detected variants were interpreted according to the American College of Medical Genetics (ACMG) guidelines. The minor allele frequency for each variant was 0.025%, 0.023%, and 0.0004% in East Asians, respectively. The DCTN1 variant found in Patient 6 might be associated with FTD. Although none of them were previously reported in dementia patients, all variants were classified as variants of unknown significance (VUS). Our report suggests that results of genetic tests in elderly patients with dementia need to be carefully interpreted. Further data accumulation of genotype-phenotype relationships and development of appropriate functional models are warranted

Biphasic Aire expression in early embryos and in medullary thymic epithelial cells before end-stage terminal differentiation

The roles of autoimmune regulator (Aire)–expressing medullary thymic epithelial cells (mTECs) in the organization of the thymic microenvironment for establishing self-tolerance are enigmatic. We sought to monitor the production and maintenance of Aire-expressing mTECs by a fate-mapping strategy in which bacterial artificial chromosome transgenic (Tg) mice expressing Cre recombinase under the control of the Aire regulatory element were crossed with a GFP reporter strain. We found that, in addition to its well recognized expression within mature mTECs, Aire was expressed in the early embryo before emergence of the three germ cell layers. This observation may help to explain the development of ectodermal dystrophy often seen in patients with AIRE deficiency. With the use of one Tg line in which Cre recombinase expression was confined to mTECs, we found that Aire+CD80high mTECs further progressed to an Aire−CD80intermediate stage, suggesting that Aire expression is not constitutive from after its induction until cell death but instead is down-regulated at the beginning of terminal differentiation. We also demonstrated that many mTECs of Aire-expressing lineage are in close contact with thymic dendritic cells. This close proximity may contribute to transfer of tissue-restricted self-antigens expressed by mTECs to professional antigen-presenting cells

HIV感染症およびAIDS患者の臨床的特徴

【Introduction】The survival rate in patients with HIV infection and acquired immunodeficiency syndrome （AIDS） has been improved dramatically due to the advances in anti-HIV drug therapy, while aging-associated complications become a critical issue. The incidence of sudden occurrence of AIDS without prior detection of HIV infection, so called “Ikinari AIDS”, still remains high. 【Objective】We retrospectively analyzed the incidence and clinical characteristics of HIV/AIDS patients in both Tokushima University Hospital and Tokushima Prefectural Central Hospital. 【Results】Eighty four patients （74 males and 10 females） with a median age of 39 years old （range 16 - 85） were enrolled. Thirty-four patients （40.5％） were diagnosed with “Ikinari AIDS” from 2001 to 2020. All 4 patients were diagnosed with “Ikinari AIDS” after 2020. AIDS-defining illnesses were diagnosed as follows ; pneumocystis pneumonia in 21 cases, CMV infection in 8 cases and candidiasis in 6 cases. All patients over 60 years old were suffered from AIDS. Other complications included syphilis in 17 cases, hepatitis B infection in 12 and herpes zoster in 7. 【Discussion/Conclusion】In Tokushima, the incidence rate of “Ikinari AIDS” appeared to be higher than that of national average. COVID - 19 pandemic hampered the public health care services of awareness-raising activity for HIV infection and telephone consultations about HIV, which may become more lease asymptomatic HIV patients without diagnosis. For early diagnosis of HIV/AIDS, it is becoming more important to share information to make early screening of HIV infection among medical staffs, such as medical doctors, dentists, nurses, pharmacists and MSWs

先天性血友病患者の移行期の実態

【Introduction】Congenital hemophilia is a category of hemorrhagic disease caused by a genetic defect in the production of coagulation factors. It is treated by administering regular coagulation factor injections on an ongoing basis. Hemophilia is a hereditary illness, often causing social and psychological problems as a result of the disease. To analyze the objective effects of hemophilia, we conducted a retrospective analysis in Tokushima University Hospital. 【Result】All ２３ cases were men between the ages of２０and７２. Hemophilia A was present in１７cases, and hemophilia B was present in six. Nineteen out of ２３ cases were severe, and the others were intermediate. Medical assessments were conducted at pediatrics in seven cases and hematology in １６ cases. Adoption of the self-injection technique was not realized in five cases. Seventeen cases were complicated by hemophilic arthropathy, seven with human immunodeficiency virus（HIV）, and １２ with hepatitis C virus. Eight participants were unemployed, and１７were unmarried. 【Discussion】 Many adult hemophilia patients still visit pediatrics in our hospital. Hemophilia in the period of growth between adolescence and young adulthood is often accompanied by life-altering events such as entering higher education, marriage, and work experience. Therefore, collaboration among professionals of multiple occupations, such as doctors, nurses, pharmacists, medical social workers, and clinical psychologists, is essential. Furthermore, there are many cases of HIV and hepatitis C virus infections complicating hemophilia study due to the stigma surrounding HIV-tainted blood. 【Conclusion】It is imperative that we establish a long-term, sustainable, and multi-disciplinary transitional care and medical support system for patients and their families

SlLAX1 is Required for Normal Leaf Development Mediated by Balanced Adaxial and Abaxial Pavement Cell Growth in Tomato

Leaves are the major plant organs with a primary function for photosynthesis. Auxin controls various aspects of plant growth and development, including leaf initiation, expansion and differentiation. Unique and intriguing auxin features include its polar transport, which is mainly controlled by the AUX1/LAX and PIN gene families as influx and efflux carriers, respectively. The role of AUX1/LAX genes in root development is well documented, but the role of these genes in leaf morphogenesis remains unclear. Moreover, most studies have been conducted in the plant model Arabidopsis thaliana, while studies in tomato are still scarce. In this study, we isolated six lines of the allelic curly leaf phenotype ‘curl’ mutants from a γ-ray and EMS (ethyl methanesulfonate) mutagenized population. Using a map-based cloning strategy combined with exome sequencing, we observed that a mutation occurred in the SlLAX1 gene (Solyc09g014380), which is homologous to an Arabidopsis auxin influx carrier gene, AUX1 (AtAUX1). Characterization of six alleles of single curl mutants revealed the pivotal role of SlLAX1 in controlling tomato leaf flatness by balancing adaxial and abaxial pavement cell growth, which has not been reported in tomato. Using TILLING (Targeting Induced Local Lesions IN Genome) technology, we isolated an additional mutant allele of the SlLAX1 gene and this mutant showed a curled leaf phenotype similar to other curl mutants, suggesting that Solyc09g014380 is responsible for the curl phenotype. These results showed that SlLAX1 is required for normal leaf development mediated by balanced adaxial and abaxial pavement cell growth in tomato

Evaluation of efficacy and safety of lascufloxacin for nursing and healthcare associated pneumonia: single-arm, open-label clinical trial: A study protocol

Background: Lascufloxacin hydrochloride (LSFX) is a quinolone antibiotic that inhibits DNA gyrase and topoisomerase IV of bacteria, it is anticipated to minimize antibiotic resistance in bacteria. It exhibits antibacterial activity against a relatively wide range of bacterial species, including anaerobic bacteria, and its efficacy and safety against community-acquired pneumonia have been shown; however, its efficacy and safety against nursing and healthcare associated pneumonia (NHCAP) have not been verified.Methods/Design: Here, a single-arm, open-label, uncontrolled study was conducted in which LSFX was administered to patients with NHCAP at 24 facilities. The research subjects (77 cases) were orally administered 75 mg of LSFX once a day for 7 days. The primary endpoint was the clinical efficacy at the time of test of cure (TOC) (TOC; 5–10 days after the end of LSFX administration), while the secondary endpoints were the efficacy at the time of end of treatment, early clinical efficacy, microbiological efficacy at the time of TOC and end of treatment, and safety evaluation of LSFX.Discussion: NHCAP is a common pneumonia in clinical settings and a notable pneumonia whose mortality is high compared to community-acquired pneumonia. The present study showed the efficacy and safety of LSFX against NHCAP, which could lead to a larger number of therapeutic options for NHCAP

Decreased circulating branched-chain amino acids are associated with development of Alzheimer’s disease in elderly individuals with mild cognitive impairment

BackgroundNutritional epidemiology has shown that inadequate dietary protein intake is associated with poor brain function in the elderly population. The plasma free amino acid (PFAA) profile reflects nutritional status and may have the potential to predict future changes in cognitive function. Here, we report the results of a 2-year interim analysis of a 3-year longitudinal study following mild cognitive impairment (MCI) participants.MethodIn a multicenter prospective cohort design, MCI participants were recruited, and fasting plasma samples were collected. Based on clinical assessment of cognitive function up to 2 years after blood collection, MCI participants were divided into two groups: remained with MCI or reverted to cognitively normal (“MCI-stable,” N = 87) and converted to Alzheimer’s disease (AD) (“AD-convert,” N = 68). The baseline PFAA profile was compared between the two groups. Stratified analysis based on apolipoprotein E ε4 (APOE ε4) allele possession was also conducted.ResultsPlasma concentrations of all nine essential amino acids (EAAs) were lower in the AD-convert group. Among EAAs, three branched-chain amino acids (BCAAs), valine, leucine and isoleucine, and histidine (His) exhibited significant differences even in the logistic regression model adjusted for potential confounding factors such as age, sex, body mass index (BMI), and APOE ε4 possession (p < 0.05). In the stratified analysis, differences in plasma concentrations of these four EAAs were more pronounced in the APOE ε4-negative group.ConclusionThe PFAA profile, especially decreases in BCAAs and His, is associated with development of AD in MCI participants, and the difference was larger in the APOE ε4-negative population, suggesting that the PFAA profile is an independent risk indicator for AD development. Measuring the PFAA profile may have importance in assessing the risk of AD conversion in the MCI population, possibly reflecting nutritional status.Clinical trial registration[https://center6.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000025322], identifier [UMIN000021965]

Study protocol for efficacy and safety of steroid-containing mouthwash to prevent chemotherapy-induced stomatitis in women with breast cancer: a multicentre, open-label, randomised phase 2 study

INTRODUCTION: Stomatitis is a frequent adverse event in patients undergoing chemotherapy for breast cancer. Stomatitis can hamper oral nutrition resulting in malnutrition, reduce quality of life and introduce the need for dose reductions and interruption of chemotherapy; however, there is currently no standard approach for preventing chemotherapy-induced stomatitis. We aimed to assess the safety and efficacy of a dexamethasone-based elixir mouthwash for preventing chemotherapy-induced stomatitis in patients with early breast cancer. METHODS AND ANALYSIS: In this multicenter, randomised, controlled phase 2 trial, we will randomly assign 120 women with early breast cancer undergoing chemotherapy to use of a dexamethasone-based elixir or standard oral care, to compare their preventive effects on chemotherapy-induced stomatitis. Patients will be assigned in a 1:1 ratio. Patients in the intervention group will receive chemotherapy, oral care and a dexamethasone-based elixir (10?mL 0.1?mg/mL; swish for 2?min and spit, four times daily for 9 weeks), and patients in the control group will receive chemotherapy and oral care. The primary endpoint is the difference in incidence of stomatitis between the two groups. The sample size allows for the detection of a minimum difference of 20% in the incidence of stomatitis between the two groups. Secondary endpoints are severity of stomatitis, duration of stomatitis, completion rate of chemotherapy and adverse events. ETHICS AND DISSEMINATION: All participants signed a written consent form, and the study protocol has been reviewed and approved by the Clinical Research Review Board of Nagasaki University (CRB7180001).
