Development of Machine Learning Model for Selecting the 1st Coil in the Treatment of Cerebral Aneurysms by Coil Embolization.

To achieve good treatment outcomes in coil embolization for cerebral aneurysms, it is important to select an appropriate 1st coil for each aneurysm since it serves as a frame to support the subsequent coils to be deployed. However, its selection as appropriate size and length from a wide variety of lineups is not easy, especially for inexperienced neurosurgeons. We developed a machine learning model (MLM) to predict the optimal size and length of the 1st coil by learning information on patients and aneurysms that were previously treated with coil embolization successfully.

This cross-sectional study approached 2,510 welfare facilities for persons with disabilities across Japan.

Machine learning for predicting successful extubation in patients receiving mechanical ventilation.

Ventilator liberation is one of the most critical decisions in the intensive care unit; however, prediction of extubation failure is difficult, and the proportion thereof remains high. Machine learning can potentially provide a breakthrough in the prediction of extubation success. A total of seven studies on the prediction of extubation success using machine learning have been published.

Machine Learning Prediction for Supplemental Oxygen Requirement in Patients with COVID-19.

Background: The coronavirus disease (COVID-19) poses an urgent threat to global public health and is characterized by rapid disease progression even in mild cases. In this study, we investigated whether machine learning can be used to predict which patients will have a deteriorated condition and require oxygenation in asymptomatic or mild cases of COVID-19.

Methods: This single-center, retrospective, observational study included COVID-19 patients admitted to the hospital from February 1, 2020, to May 31, 2020, and who were either asymptomatic or presented with mild symptoms and did not require oxygen support on admission.

Photochemical Properties of Red-Emitting Tris(cyclometalated) Iridium(III) Complexes Having Basic and Nitro Groups and Application to pH Sensing and Photoinduced Cell Death.

Cyclometalated iridium(III) complexes, because of their photophysical properties, have the potential for use as luminescent probes for cellular imaging. We previously reported on a pH-activatable iridium complex that contains three N,N-diethylamino groups, namely, fac-Ir(deatpy)3 5, which was synthesized via a regioselective aromatic substitution reaction at the 5'-position with tolylpyridine groups of fac-Ir(tpy)3 2. It was found that 5 shows a considerable enhancement in emission intensity in the pH range from neutral to slightly acidic (pH 6.

Predictors, including blood, urine, anthropometry, and nutritional indices, of all-cause mortality among institutionalized individuals with intellectual disability.

As the life expectancy of people with intellectual disability (ID) increases, it is becoming necessary to understand factors affecting survival. However, predictors that are typically assessed among healthy people have not been examined. Predictors of all-cause mortality, including blood, urine, anthropometry, and nutritional indices, were examined among institutionalized people with ID.

Simultaneous sinus lifting and alveolar distraction of a severely atrophic posterior maxilla for oral rehabilitation with dental implants.

We retrospectively reviewed a new preimplantation regenerative augmentation technique for a severely atrophic posterior maxilla using sinus lifting with simultaneous alveolar distraction, together with long-term oral rehabilitation with implants.

Non-invasive temperature measurement by using phase changes in electromagnetic waves in a cavity resonator.

Purpose: To improve the efficacy of hyperthermia treatment, a novel method of non-invasive measurement of changes in body temperature is proposed. The proposed method is based on phase changes with temperature in electromagnetic waves in a heating applicator and the temperature dependence of the dielectric constant. An image of the temperature change inside a body is reconstructed by applying a computed tomography algorithm.

Regioselective aromatic substitution reactions of cyclometalated Ir(III) complexes: synthesis and photochemical properties of substituted Ir(III) complexes that exhibit blue, green, and red color luminescence emission.

In this manuscript, the regioselective halogenation, nitration, formylation, and acylation of Ir(tpy)(3) and Ir(ppy)(3) (tpy = 2-(4'-tolyl)pyridine and ppy = 2-phenylpyridine) and the subsequent conversions are described. During attempted bromination of the three methyl groups in fac-Ir(tpy)(3) using N-bromosuccinimide (NBS) and benzoyl peroxide (BPO), three protons at the 5'-position (p-position with respect to the C-Ir bond) of phenyl rings in tpy units were substituted by Br, as confirmed by (1)H NMR spectra, mass spectra, and X-ray crystal structure analysis. It is suggested that such substitution reactions of Ir complexes proceed via an ionic mechanism rather than a radical mechanism.

The distributions and correlates of serum albumin levels in institutionalised individuals with intellectual and/or motor disabilities.

The serum albumin level is a widely accepted indicator of nutritional status in healthy adults and elderly individuals. However, there are few data regarding the distribution and correlates of serum albumin levels in individuals with intellectual and/or motor disabilities. We conducted a cross-sectional study at a public facility for individuals with intellectual and/or motor disabilities in Ibaraki prefecture, Japan.

Survey on the implementation of blood and urine examinations at Japanese institutions and schools for individuals with intellectual disabilities and/or motor disabilities in 1998.

Objectives: Few national surveys have been conducted on the health and nutrition of disabled people in Japan, and as a result, the actual health and nutritional status of this population group has not been clarified. The aim of the present study is to clarify the following hypotheses: nutritional assessment is not carried out at institutions and schools for individuals with intellectual disabilities (ID) and/or motor disabilities (MD), and there are marked differences in implementation rates and assessment methods (i) between institutions and schools and (ii) among the disability categories.

Methods: Questionnaires were sent to 1,080 selected institutions and schools for individuals with ID and/or MD.

Noninvasive thermometry in a reentrant resonant cavity applicator.

In order to improve the effect of hyperthermia treatment, a novel noninvasive temperature measurement method is proposed. The key mechanism of this thermometry is based on the phase change of the electrical field accompanying the temperature change inside the resonant cavity. First, the line-integrated data of this phase change distribution parallel to the electrical field are collected by rotating a cavity resonator.
