BACKGROUND:
Predicting adverse health events and implementing preventative measures are a necessary challenge. It is important for healthcare planners and policymakers to allocate the limited resource to high-risk persons. Prediction is also important for older individuals, their family members, and clinicians to prepare mentally and financially. The aim of this study is to develop a prediction model for within 11-year dependent status requiring long-term nursing care or death in older adults for each sex.
METHODS:
We carried out age-specified cohort study of community dwellers in Nisshin City, Japan. The older adults aged 64 years who underwent medical check-up between 1996 and 2000 were included in the study. The primary outcome was the incidence of the psychophysically dependent status or death or by the end of the year of age 75 years. Univariable logistic regression analyses were performed to assess the associations between candidate predictors and the outcome. Using the variables with p-values less than 0.1, multivariable logistic regression analyses were then performed with backward stepwise elimination to determine the final predictors for the model.
RESULTS:
Of the 1525 female participants at baseline, 105 had an incidence of the study outcome. The final prediction model consisted of 15 variables, and the c-statistics for predicting the outcome was 0.763 (95% confidence interval [CI] 0.714-0.813). Of the 1548 male participants at baseline, 211 had incidence of the study outcome. The final prediction model consisted of 16 variables, and the c-statistics for predicting the outcome was 0.735 (95% CI 0.699-0.771).
CONCLUSIONS
We developed a prediction model for older adults to forecast 11-year incidence of dependent status requiring nursing care or death in each sex. The predictability was fair, but we could not evaluate the external validity of this model. It could be of some help for healthcare planners, policy makers, clinicians, older individuals, and their family members to weigh the priority of support.

The yips represent a disorder that makes it challenging for an individual to perform automatic and coordinated movements in sports activities. The cause of the yips is not sufficiently clarified, and limited information is available regarding throwing yips in baseball. Therefore, this study was designed to clarify the incidence and characteristics of the throwing yips among college baseball players. Total 107 players of the college baseball team participated in the study and completed the questionnaire by answering questions about their experience of the yips (loss of control to throw the ball accurately for more than 1 month), the symptom intensity, and changes observed in the symptoms in different situations. The 47.1% of players met the definition of throwing yips. The symptoms of the yips were more pronounced with short-distances and low intensity of throwing. Moreover, there were various subjective symptoms, such as the issue about co-contraction of the upper limb, sensory function, body ownership, and movement planning. Various physical symptoms associated with throwing yips suggest that the yips are not only a disorder of motor skills, but result from movement disorders. The present results show that the occurrence of the yips depends on the throwing condition; this finding provides useful insights into the mechanism and the treatment of the yips. Interdisciplinary studies that aim to elucidate the cause of the yips and develop effective intervention are necessary.

We began providing comprehensive cardiac rehabilitation for congestive heart failure (CHF) in 2014 at our institution, using an original pamphlet and heart failure notebook to provide life guidance for CHF. However, the life guidance rate was lower in 2017 (61%) than it was in 2014 (77%). The objective of this study was to investigate the awareness of life guidance among nurses. We administered a questionnaire survey regarding life guidance to 28 nurses in December 2018. Among the 27 respondents, 26 nurses (96%) had high motivation and 21 (80%) felt a sense of accomplishment. Responses to the “most important point in life guidance” were “understanding living condition” by 14 nurses, “heart failure notebook” by 9 nurses, and “guidance using the pamphlet” by 6 nurses. Fifteen nurses (58%) felt that the guidance had become routine in nature, and 5 nurses (19%) were worried about their instruction. The nurses were motivated to provide life guidance, but they also felt that the guidance had become routine because they had been providing the same guidance for many years. We consider that the factors related to the lower life guidance rate are the routine/repetitive nature of the guidance and concerns about instruction. Going forward, we need to review the content of the guidance and the teaching approach.

An aortoesophageal fistula is a critical condition with high operative mortality. A case of aortoesophageal fistula following thoracic endovascular aneurysm repair is reported. The patient was a 72-year-old man complaining of dysphagia who underwent stent grafting for a saccular aneurysm of the descending aorta that was compressing the esophagus four months earlier. Endoscopic examination showed perforation of the aneurysm into the esophagus with severe stenosis. The aneurysmal sac was filled with thrombus. Aortography demonstrated a type I endoleak from the lesser curvature of the aortic arch, draining into the aneurysmal sac. The patient was afebrile with moderate elevation of C-reactive protein, and the white blood cell count was normal. The patient underwent closure of the aneurysmal entry with healthy aortic wall and replacement of the descending aortic aneurysm with a prosthetic graft. The graft was isolated from the fistula by an omental flap. The patient's postoperative course was uneventful. Computed tomography performed 4 years after the surgery showed shrinkage of the aneurysmal sac. The patient has had a healthy life for 9 years since the operation.

BACKGROUND:
To let the early elderly live well, understanding how lifestyle and psychosocial factors related to a decline in competence in daily living is important.
METHODS:
We investigated the associations between lifestyle and psychosocial factors at age 64 years and a decline in the Tokyo Metropolitan Institute of Gerontology Index of Competence score of ≥ 2 points at age 70 years among the participants in comprehensive medical check-ups living in a city in Japan. Multivariable logistic regression analyses were performed separately for men and women.
RESULTS:
Of the 1113 eligible men and 1203 eligible women, 110 men and 80 women showed a deteriorated competence in daily living during the 6 years. In men, risk was increased with ≥ 2 nighttime awakenings (multivariable odds ratio [mOR] 2.14, 95% confidence interval [CI] 1.19-3.86) and living alone (mOR 4.68, 95% CI 1.22-18.0), whereas risk was significantly decreased with a medium or fast gait (mOR 0.37 and 0.21, 95% CI 0.21-0.67 and 0.08-0.58) and high academic achievement (mOR 0.32 and 0.43, 95% CI 0.19-0.53 and 0.25-0.72). In women, risk was decreased with high life satisfaction (mOR 0.39, 95% CI 0.16-0.91) and participation in community activities (mOR 0.50, 95% CI 0.29-0.86) but increased with depressive mood (mOR 1.86, 95% CI 1.09-3.18).
CONCLUSION
Living alone for men and low life satisfaction for women at age 64 years were markedly associated with the risk of a subsequent declining competence in daily living.

Recent comprehensive investigations clarified that immune microenvironment surrounding tumor cells are deeplyinvolved in tumor progression, metastasis, and response to treatment. Furthermore, several immunotherapeutic trialshave achieved successful results, and the immunotherapeutic agents are available in clinical practice. To enhancetheir demonstrated efficacy, combination of immunotherapy and ablation has begun to emerge. Local ablationshave considerable advantages as an alternative therapeutic option, especially its minimal invasiveness. In addition,local ablations have shown immune-regulatory effect in preclinical and clinical studies. Although the correspondingmechanisms are still unclear, the local ablations combined with immunotherapy have been suggested in the treatmentof several solid malignancies. This article aims to review the published data on the immune-regulatory effectsof local ablations including stereotactic body radiotherapy, cryoablation, radiofrequency ablation, and high-intensityfocusedultrasound. We also discuss the value of local ablations combined with immunotherapy. Local ablations havethe potential to improve future patient outcomes; however, the effectiveness and safety of local ablations combinedwith immunotherapy should be further investigated.

Objective To observe the impact of zotepine on the excitatory synaptic response and long term potentiation (LTP) of dentate gyrus neurons.Methods Male rabbits ( n = 20) weighting about 2.5 ~ 3.5 kg were divided into four groups randomly ( n = 5 ): control, zotepine 1.0, zotepine 2.0 and zotepine 5.0.To each rabbit,there were 60 results during 120 min.Population spike(PS) amplitude and excitory postsynaptic potential (EPSP) slope were used to be the indexes of the excitatory synaptic response of dentate gyrus neurons.The sequence was base response ( at the beginning), intraperitoneal injection of 0.5ml dimethylsulfoxide or 0.5ml zotepine-dimethylsulfoxide solution ( 1.0,2.0,5.0 mg/kg of zotepine dosage) ( after 30 min) and titanic stimulation (after 90 min).Results To 4 groups,the PS amplitude and EPSP slope after single stimuli were not significantly different from those before single stimuli.In control group, the PS amplitude and EPSP slope after titanic stimulation[(0.68 ± 0.052)mV and(0.633 ± 0.024 )mV/ms] were significantly different from those before injection[(0.266 ±0.008) mV and(0.246 ±0.010) mV/ms] (P<0.05 ~0.01 ) ,and LTP were induced.LTP were not induced after titanic stimulation in group zotepine 1.0,2.0 and 5.0.After titanic stimulation, the PS amplitude and EPSP slope in group zotepine 5.0[(0.277 ±0.008)mV and(0.296 ±0.007) mV/ms] were significantly different from those in group control(P< 0.05).Conclusion Zotepine had little effect on the excitatory synaptic response of dentate gyrus neurons after single stimuli in perforant path, while it blocked the induction of LTP in perforant path-dentate gyrus pathway.

The promotion of clinical research in Japan requires the establishment of a formal and systematic education and training program for clinicians to ensure they become effective clinician investigators. The first of its kind in Japan, a formal 1-year masters-degree-level training program (MCR course) was started at Kyoto University School of Medicine and Public Health. The first 28 students graduated in 2008, with most returning to their original clinical institutions.
1) As follow-up, we conducted a self-administered questionnaire survey of all 28 graduates (response rate, 86%) concerning the current status of clinical research and problems encountered at their institutions.
2) Almost 40% of respondents (n=24) reported "no time" or "no research collaborators" for clinical research.
3) Twenty respondents (83%) have attempted to promote clinical research at their hospital or workplace, but only 1 has received institutional support.
4) Over half of the respondents (54%) would like to be working in both clinical research and clinical practice at their hospital in the future (10-year timescale). Forty-two percent of respondents had a concrete image of the clinical researcher's career path.
5) Although open to improvement, the MCR program presents a concrete model for the education of clinical researchers. These findings suggest that promoting the conduct of clinical research requires the implementation of a support system and adjustment of personal and physical infrastructure.
