Information and communication technology equipment and services for remote monitoring and health management: Survey of services and their classification for use in home care nursing

This study aims to improve the quality of home nursing care for the elderly. The report presents web-based information about devices and services for remote monitoring and health management using information and communication technology and about how they can improve home care nursing station efficiency in Japan. The search terms "elderly people," "watch over," and "service," plus "sensor" were used to narrow the search. After repeating the search using a chained search for materials and links extracted from those search results, services for home care stations particularly addressing the remote monitoring of elderly people were selected and extracted. Early detection of abnormalities for support by home health nurse responsibilities for observing the general condition of the patient was chosen as the main evaluation index of usefulness. The contractor and service cost were secondary evaluation axes. Results show 9 information communication devices and services for real-time monitoring of the elderly persons’ vital signs in real time for 24 hr, 2 of which are highly useful for early detection of abnormalities and subsequent response. Results suggest that other services might be more useful, depending on how they are used, and that general-purpose services with minimum functions and low cost of introduction and maintenance can provide more opportunities for utilization. Providing these services on a BtoBtoC model and responding to patients’ medical needs can supplement home care nursing station work, increase human resource and time efficiencies, and give patients "the feeling that a nurse is always at their bedside,” even when far away

Mechanisms Underlying the Comorbidity of Schizophrenia and Type 2 Diabetes Mellitus

The mortality rate of patients with schizophrenia is high, and life expectancy is shorter by 10 to 20 years. Metabolic abnormalities including type 2 diabetes mellitus (T2DM) are among the main reasons. The prevalence of T2DM in patients with schizophrenia may be epidemiologically frequent because antipsychotics induce weight gain as a side effect and the cognitive dysfunction of patients with schizophrenia relates to a disordered lifestyle, poor diet, and low socioeconomic status. Apart from these common risk factors and risk factors unique to schizophrenia, accumulating evidence suggests the existence of common susceptibility genes between schizophrenia and T2DM. Functional proteins translated from common genetic susceptibility genes are known to regulate neuronal development in the brain and insulin in the pancreas through several common cascades. In this review, we discuss common susceptibility genes, functional cascades, and the relationship between schizophrenia and T2DM. Many genetic and epidemiological studies have reliably associated the comorbidity of schizophrenia and T2DM, and it is probably safe to think that common cascades and mechanisms suspected from common genes' functions are related to the onset of both schizophrenia and T2DM. On the other hand, even when genetic analyses are performed on a relatively large number of comorbid patients, the results are sometimes inconsistent, and susceptibility genes may carry only a low or moderate risk. We anticipate future directions in this field

Sex-inducing effects toward planarians widely present among parasitic flatworms

Summary Various parasitic flatworms infect vertebrates for sexual reproduction, often causing devastating diseases in their hosts. Consequently, flatworms are of great socioeconomic and biomedical importance. Although the cessation of parasitic flatworm sexual reproduction is a major target of anti-parasitic drug design, little is known regarding bioactive compounds controlling flatworm sexual maturation. Using the planarian Dugesia ryukyuensis, we observed that sex-inducing substances found in planarians are also widespread in parasitic flatworms, such as monogeneans and flukes (but not in tapeworms). Reverse-phase HPLC analysis revealed the sex-inducing substance(s) eluting around the tryptophan retention time in the fluke Calicophoron calicophorum, consistent with previous studies on the planarian Bipalium nobile, suggesting that the substance(s) is likely conserved among flatworms. Moreover, six of the 18 ovary-inducing substances identified via transcriptome and metabolome analyses are involved in purine metabolism. Our findings provide a basis for understanding and modifying the life cycles of various parasitic flatworms.journal articl

Anti-N-Methyl-D-Aspartate Receptor Encephalitis in Psychiatry

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a recently-discovered autoimmune disorder in which antibodies target NMDAR in the brain. The number of reported cases of anti-NMDAR encephalitis has increased rapidly. Anti-NMDAR encephalitis can be mistakenly diagnosed as psychiatric disorders because many patients present with prominent psychiatric symptoms and visit psychiatric institutions first. Thus, psychiatrists should cultivate a better understanding of anti-NMDAR encephalitis. In this review, we present the mechanisms, epidemiology, symptoms and clinical course, diagnostic tests, treatment and outcomes of patients with anti-NMDAR encephalitis. Furthermore, we discuss the diversity of clinical spectra of anti-NMDAR encephalitis, and demonstrate a differential diagnosis of psychiatric disease from the perspective of psychiatry

Smooth sectioning of biological samples by FIB-TOF-SIMS

Spheroids, which are three-dimensionally cultured cells that resemble actual living organisms, have been attracting attention. FIB-TOF-SIMS (Focused Ion Beam Time-of-Flight Mass Spectrometry) is capable of simultaneous mass imaging of multiple elements without the need for labeling. FIB-TOF-SIMS is expected to process the spheroid and image the cross-sectional components. However, FIB processing of spheroids larger than 100μm often results in uneven cross sections due to the so-called curtain effect. The unevenness of the cross-section affects the sputtering and hinders component imaging. In this experiment, we considered the processing of spheroids by FIB from multiple directions to suppress the curtain effect. The curtain effect was evaluated by comparing the processing from one direction and from multiple directions

Impact of relative dose intensity (RDI) in CHOP combined with rituximab (R-CHOP) on survival in diffuse large B-cell lymphoma

<p>Abstract</p> <p>Background</p> <p>Recently, maintaining higher relative dose intensity (RDI) of chemotherapeutic drugs has become a widespread practice in an attempt to achieve better outcomes in the treatment of aggressive lymphoma. The addition of rituximab to chemotherapy regimens has significantly improved outcome in diffuse large B-cell lymphoma (DLBL). However, it is unknown if higher RDI in chemotherapy when combined with rituximab leads to a better outcome in aggressive B-cell lymphoma.</p> <p>Methods</p> <p>We retrospectively evaluated the impact of the RDI of initial chemotherapy (consisting of cyclophosphamide, doxorubicin, vincristine and prednisolone with rituximab (R-CHOP) on outcome in 100 newly diagnosed DLBL patients.</p> <p>Results</p> <p>A multivariate Cox regression model showed that RDI trended towards a significant association with mortality [hazard ratio per 0.1 of RDI = 0.8; 95% confidence interval 0.6–1.0; <it>P </it>= 0.08]. Additionally, on multivariate logistic analysis, advanced age was a significant factor for reduced RDI.</p> <p>Conclusion</p> <p>Our data suggest that in DLBL patients, mortality was affected by RDI of R-CHOP as the initial treatment, and the retention of a high RDI could therefore be crucial.</p

High time resolved electron temperature measurements by using the multi-pass Thomson scattering system in GAMMA 10/PDX

High time resolved electron temperature measurements are useful for fluctuation study. A multi-pass Thomson scattering (MPTS) system is proposed for the improvement of both increasing the TS signal intensity and time resolution. The MPTS system in GAMMA 10/PDX has been constructed for enhancing the Thomson scattered signals for the improvement of measurement accuracy. The MPTS system has a polarization-based configuration with an image relaying system. We optimized the image relaying optics for improving the multi-pass laser confinement and obtaining the stable MPTS signals over ten passing TS signals. The integrated MPTS signals increased about five times larger than that in the single pass system. Finally, time dependent electron temperatures were obtained in MHz sampling
