Objectives: This study reviewed the effect of vocal exercise on patients with cervical spinal cord injury (SCI).Methods: An electronic search of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase databases was conducted for relevant studies published between 1980 and 2022. The review included studies that used randomized controlled trials to examine the effects of vocal exercise on people with cervical SCI.Results: We screened 1351 articles, of which 4 studies were eligible for inclusion. Vocal exercises were conducted two or three times a week for 12–24 weeks. Random sequences were adequately generated in all studies. All studies used respiratory function as the main outcome, and three studies used vocal quality as an outcome. In all studies, there were no dropouts other than those caused by unexpected illness. Vocal exercises were reported to have a positive effect on respiratory function in all studies and on voice quality in three studies. Meta-analysis was not possible because of the heterogeneity of the studies.Conclusions: Vocal exercise for SCI is a sustainable method that does not require special equipment or skills. More studies with large sample sizes are needed to confirm the effects of vocal exercises in patients with cervical SCI.

エージェントに快と不快の情報を導入することで、強化学習分野における汎用性の獲得を目指している。現在の強化学習では報酬は一般的にエンジニアが定義する情報であり、エージェントは設定された報酬に対して獲得に繋がった行動を価値として算出し、 次回の試行時の行動選択に役立てる。しかし強化学習は特化型人工知能と呼ばれるように転移学習が困難という性質がある。本モデルでは、報酬としての快という情報を不快の解消として位置付けることで報酬情報を不快を発生させた事象と紐付け、エージェントに自律的に何が報酬(不快を解消させるのか)なのかという情報を獲得させるとともに、報酬情報を区別する能力を獲得させることで複数のタスクを同一のエージェントによって学習可能な状態にすることを目標としている。

The dehydrogenation of isobutane to isobutene was accomplished using a NiO/γ-Al2O3 catalyst. Furthermore, significant improvement in the time-on-stream yield of isobutene was achieved. During the normal catalytic dehydrogenation of alkanes, the catalyst is covered by carbon deposition generated during the reaction, which significantly reduces the activity with time-on-stream. Therefore, no examples of the catalytic dehydrogenation of isobutane have yet been reported. This study used either ethane or propane as a source of isobutane to examine whether the activity was improved with time-on-stream. As a result, in the dehydrogenations of both ethane and propane on a NiO/γ-Al2O3 catalyst, the catalytic activity decreased with time-on-stream when the supporting amount of NiO was small. In contrast, when the supporting amount of NiO was large, the catalytic activity improved with time-on-stream. Using a NiO/γ-Al2O3 catalyst with small and large NiO loadings led to similar results to those of isobutane dehydrogenation. In addition, it was confirmed that the dehydrogenation activity was improved with time-on-stream in the catalytic dehydrogenations of ethane, propane, and isobutane using high NiO loadings. The behavior using a moderate amount of NiO loading, which was not detected in the dehydrogenation of isobutane, was also observed, which resulted in a maximum yield of either ethylene or propylene at 2.0 or 3.25 h on-stream, respectively. We concluded that the reason the catalytic activity did not improve with time-on-stream when using a NiO/γ-Al2O3 catalyst was because the supporting amount of NiO was negligible. These results demonstrate that the activity with time-on-stream could also be improved in the dehydrogenations of other alkanes.

Objectives: This study aimed to determine the relationship between the number of board-certified physiatrists and the amount of inpatient rehabilitation delivered.Materials and Methods: We analyzed open data from 2017 in the National Database of Health Insurance Claims and Specific Health Checkups of Japan and compared the volume of inpatient rehabilitation services between prefectures to examine regional disparities. We also examined the relationship between the volume of rehabilitation services provided and the number of board-certified physiatrists.Results: The population-adjusted number of inpatient rehabilitation units per prefecture ranged from a maximum of 659,951 to a minimum of 172,097, a disparity of 3.8-fold. The population-adjusted number of board-certified physiatrists was 4.8 in the highest region and 0.8 in the lowest region, a disparity of 5.8-fold. The population-adjusted number of board-certified physiatrists was significantly correlated with the population-adjusted total number of inpatient rehabilitation units (r=0.600, P<0.001). Correlations were between the number of board-certified physiatrists and the number of rehabilitation units in cerebrovascular and orthopedic services, but not in cardiovascular, respiratory, or oncology services.Conclusion: Large regional disparities manifested in the amount of inpatient rehabilitation provided in Japan. An association was found between the number of board-certified physiatrists and rehabilitation units delivered. It may be necessary to train more BCPs in regions with fewer units to eliminate these disparities.

A 72-year-old lady with atrial fibrillation and chronic renal failure was hospitalized due to bradycardic shock with electrocardiographic QRS prolongation. She had experienced limb shaking two days before hospitalization, and additionally developed hallucinations one day before admission. Pilsicainide intoxication was diagnosed from a review of her medications and electrocardiographic findings. Consequently, continuous hemodiafiltration was performed resulting in a resolution of the hallucinations and the QRS prolongation. This is a rare case of psychiatric symptoms caused by pilsicainide intoxication. It is important to know the mode of excretion of a drug and to adjust its dose, so that such drug-related incidents can be avoided.
