Study of childcare anxieties and way coping in O city

本研究の目的は,母親たちが育児に関して直面している不安を把握し,その不安に対する保健師の対処の実態を明らかにすることである｡そこでO市にあるN保健センターの家庭訪問と月1回の育児相談会において,保健師が受けた育児に関する相談を分析した｡対象はN保健センター管内の4つの地区で,1歳2ヶ月未満の児を持つ母親からの216件の相談内容である｡その結果,母親たちの育児不安で最も多かったのは児の身体や栄養についてであった｡さらに不安は出産順位によっても差があり,また児の月齢により変化し,その内容は児の成長発達と深く関係していた｡そして,育児に関する情報は増えているものの,個別性に欠けていることや,母親たちの知識に偏りがあることも明らかになった｡これらの結果をもとに,現在の母親が抱える不安の傾向を考察し,N保健センターで実施している育児支援活動を踏まえ,母親の不安の対処について検討した｡The purpose of this study is to identify childcare anxieties of mothers and how public health nurses cope with them. The data was collected from the contents of 216 consultations of mothers with children under 14th months of age carried by public health nurses of N public health center, O city. It was revealed that most of the consultations were about child's physical and nutritious concerns. The childcare anxieties associated with growth and birth order and the child's age in months. Moreover, we found that even though there is a large volume of information available about childcare, it is too general. Based on the research findings, we made clear tendency of childcare anxiety of mothers and how the public health nurses coped with them

Na依存性PiトランスポーターNpt2cは、KlothoノックアウトマウスPi恒常性において成長期と成熟期では異なる作用を有する

SLC34A3/NPT2c/NaPi-2c/Npt2c is a growth-related NaPi cotransporter that mediates the uptake of renal sodium-dependent phosphate (Pi). Mutation of human NPT2c causes hereditary hypophosphatemic rickets with hypercalciuria. Mice with Npt2c knockout, however, exhibit normal Pi metabolism. To investigate the role of Npt2c in Pi homeostasis, we generated α-klotho−/−/Npt2c−/− (KL2cDKO) mice and analyzed Pi homeostasis. α-Klotho−/− (KLKO) mice exhibit hyperphosphatemia and markedly increased kidney Npt2c protein levels. Genetic disruption of Npt2c extended the lifespan of KLKO mice similar to that of α-Klotho−/−/Npt2a−/− mice. Adult KL2cDKO mice had hyperphosphatemia, but analysis of Pi metabolism revealed significantly decreased intestinal and renal Pi (re)absorption compared with KLKO mice. The 1,25-dihydroxy vitamin D3 concentration was not reduced in KL2cDKO mice compared with that in KLKO mice. The KL2cDKO mice had less severe soft tissue and vascular calcification compared with KLKO mice. Juvenile KL2cDKO mice had significantly reduced plasma Pi levels, but Pi metabolism was not changed. In Npt2cKO mice, plasma Pi levels began to decrease around the age of 15 days and significant hypophosphatemia developed within 21 days. The findings of the present study suggest that Npt2c contributes to regulating plasma Pi levels in the juvenile stage and affects Pi retention in the soft and vascular tissues in KLKO mice

A Role of Intestinal Alkaline Phosphatase 3 (Akp3) in Inorganic Phosphate Homeostasis

Background/Aims: Hyperphosphatemia is a serious complication of late-stage chronic kidney disease (CKD). Intestinal inorganic phosphate (Pi) handling plays an important role in Pi homeostasis in CKD. We investigated whether intestinal alkaline phosphatase 3 (Akp3), the enzyme that hydrolyzes dietary Pi compounds, is a target for the treatment of hyperphosphatemia in CKD. Methods: We investigated Pi homeostasis in Akp3 knockout mice (Akp3-/-). We also studied the progression of renal failure in an Akp3-/- mouse adenine treated renal failure model. Plasma, fecal, and urinary Pi and Ca concentration were measured with commercially available kit, and plasma fibroblast growth factor 23, parathyroid hormone, and 1,25(OH)2D3 concentration were measured with ELISA. Brush border membrane vesicles were prepared from mouse intestine using the Ca2+ precipitation method and used for Pi transport activity and alkaline phosphatase activity. In vivo intestinal Pi absorption was measured with oral 32P administration. Results: Akp3-/- mice exhibited reduced intestinal type II sodium-dependent Pi transporter (Npt2b) protein levels and Na-dependent Pi co-transport activity. In addition, plasma active vitamin D levels were significantly increased in Akp3-/- mice compared with wild-type animals. In the adenine-induced renal failure model, Akp3 gene deletion suppressed hyperphosphatemia. Conclusion: The present findings indicate that intestinal Akp3 deletion affects Na+-dependent Pi transport in the small intestine. In the adenine-induced renal failure model, Akp3 is predicted to be a factor contributing to suppression of the plasma Pi concentration

The Hyper Suprime-Cam SSP Survey: Overview and Survey Design

Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan and Princeton University is using HSC to carry out a 300-night multi-band imaging survey of the high-latitude sky. The survey includes three layers: the Wide layer will cover 1400 deg$^2$ in five broad bands ($grizy$), with a $5\,\sigma$ point-source depth of $r \approx 26$. The Deep layer covers a total of 26~deg$^2$ in four fields, going roughly a magnitude fainter, while the UltraDeep layer goes almost a magnitude fainter still in two pointings of HSC (a total of 3.5 deg$^2$). Here we describe the instrument, the science goals of the survey, and the survey strategy and data processing. This paper serves as an introduction to a special issue of the Publications of the Astronomical Society of Japan, which includes a large number of technical and scientific papers describing results from the early phases of this survey.Comment: 14 pages, 7 figures, 5 tables.

Comprehensive early intervention for patients with first-episode psychosis in Japan (J-CAP): study protocol for a randomised controlled trial

<p>Abstract</p> <p>Introduction</p> <p>Comprehensive approaches for patients with psychotic symptoms play essential roles in the symptomatic and functional outcomes of patients, especially during disease onset. In Japan, the shortage of mental health services, particularly for outpatients, and community-based supports has been a major problem. The purpose of this trial is to investigate the effectiveness and affordability of 18-month comprehensive early intervention services for patients with first-episode psychosis compared with typical treatment.</p> <p>Methods</p> <p>This interventional, parallel, single-blinded (open but blinded raters trial) was effectively designed. The participants are patients with a diagnosis of F2 or F3 (International Classification of Disease, 10 th revision), with psychotic symptoms. The inclusion criteria were an age of 15-35 years, onset of psychotic symptoms within 5 years, first-episode psychosis, and residence in the catchment area of each site. Allocation will be conducted equally between case management and standard care groups. After enrollment, standard care will be provided for both groups, and community-based care to promote recovery for 18 months will be provided for the comprehensive approach group. The primary outcome will be the function domain of the global assessment of functioning scores at 18 months after enrollment. Data assessment will be performed at enrollment and 18, 36, and 60 months after enrollment. The target sample size will be 150, and registration will occur from March 1, 2011, to September 30, 2012.</p> <p>Discussion</p> <p>This trial will provide promising results about the effectiveness and cost-effectiveness of early intervention services in Japan to improve the quality and quantity of community mental health services.</p> <p>Trial registration</p> <p>This trial was registered in The University Hospital Medical Information Network Clinical Trials Registry (No. UMIN000005092).</p

A Randomized Controlled Trial of Comprehensive Early Intervention Care in Patients with First-Episode Psychosis in Japan: 1.5-year Outcomes from the J-CAP Study

The first episode of psychosis represents a critical period wherein comprehensive early intervention in psychosis (EIP) may alter the course of illness. However, evidence from randomized controlled trials that have examined the impact of comprehensive EIP care on clinical and functional recovery assessed by independent blinded raters is limited. The objective of this study was to conduct a single-blinded multicenter trial comparing comprehensive EIP care and standard care in young patients with first-episode psychosis (FEP) in Japan (J-CAP Study). A total of 77 participants with FEP (aged 15–35 years) were randomized to receive standard care or specialized comprehensive EIP care and were followed up for 1.5 years (trial no.: UMIN000005092). Function (measured with the Global Assessment of Functioning) and clinical remission (defined by internationally standardized criteria proposed by the Remission in Schizophrenia Working Group) were evaluated by independent raters who were blinded to group assignment. Dropout rate and other secondary outcomes were also examined. The specialized EIP care group had a higher clinical remission rate (odds ratio, 6.3; 95% confidence interval, 1.0–37.9) and lower treatment dropout rate (odds ratio, 0.038; 95% confidence interval, 0.002–0.923) than the standard care group, even after adjusting for baseline characteristics. Functional improvement in the specialized EIP care group was slightly higher than that in the standard care group, but this difference was not statistically significant (p = 0.195). From the results, we conclude that comprehensive EIP care may provide advantages over standard care in patients with FEP
