[A survey on the utilization of internet services to collect job information among medical students and initiation of video public relations activities for the recruitment of public health physicians based on the survey results].

Objectives　It is difficult for medical students to obtain information about public health physicians because there are very few public health physicians near them. To improve this situation, we surveyed the utilization of internet services to collect job information among medical students and produced six videos and conducted public relations activities for the recruitment of public health physicians based on the survey results.Methods　The subjects of the survey were medical students in their third year or above from 18 universities. Public health teachers in these 18 universities sent their students anonymous self-administered questionnaires created with Google Forms mainly by e-mail. The questionnaires included the following items "internet services used to collect job information," "desired length of each video for knowing job information," and "information you want to know about your future work." The responses were reflected in the length and the content of the videos and the settings for their distribution.Results　Responses were obtained from a total of 491 medical students, including 14 third-year students, 177 fifth-year students, and 300 sixth-year students. Homepages were the most frequently used online source for collecting job information (94.7%), followed by blogs (42.0%), Twitter (32.6%), and YouTube (18.9%). Medical students are less likely to use social networking services for collecting job information compared with non-medical job-hunting students. Regarding the length of the videos, 55.8% of the respondents preferred the length of one video to be less than 5 minutes, and 95.1% preferred it to be less than 10 minutes. Almost all of the respondents (93.1%) wanted to know the atmosphere of young public health physicians, and 74.1% also wanted to know the atmosphere of veteran physicians. Based on these results, we selected six public health physicians including young and veteran physicians and produced interview videos that conveyed the atmosphere of each doctor within 5 minutes per person. We refurbished the banner on the top page of the Japanese Association of Public Health Center Directors so that the videos uploaded to YouTube could be watched.Conclusion　We clarified the current situation of the utilization of internet services for job-hunting activities among medical students and were able to initiate video public relations activities for the recruitment of public health physicians in accordance with the needs. It is necessary to increase awareness of the video platform among medical students and clinicians by deepening cooperation with local governments, universities, and medical institutions and expanding the human network both online and in person.

Assessment of the effects of a group intervention program used in home-dwelling elderly individuals to promote home exercise and prevent locomotive syndrome.

[Purpose] We assessed the effects of a group intervention program used in home-dwelling elderly individuals to promote home exercise and prevent locomotive syndrome. [Participants and Methods] Pre- and post-intervention evaluations were performed in all participants. Group intervention was performed thrice between the pre- and post-intervention evaluations in all participants. A total of 19 elderly individuals participated in the pre- and post-intervention evaluations. Tests used for evaluation were the two-step test, standing-up test, and 25-question geriatric locomotive function scale. [Results] Among all participants in this study, 12 who performed all 3 aforementioned tests were classified as the non-absence group, whereas 7 who were absent more than once were classified as the absence group. We examined intergroup differences with respect to changes between the pre- and post-intervention evaluations, and we observed significant changes only in the results of the two-step test. [Conclusion] We conclude that low-frequency intervention in the form of workshops led to positive results with respect to improved physical function in home-dwelling elderly individuals.

GERD and sleep disturbances.

Gastroesophageal reflux disease(GERD) is strongly associated with sleep disturbances. Several studies have shown that gastroesophageal reflux disease is strongly associated with sleep disturbances. Proton pump inhibitor(PPI) therapy improves subjective sleep parameters in GERD patients; however, the effects of this therapy on objective sleep parameters remain controversial. Numerous factors such as stress, lifestyle, and surrounding circumstances affect sleep status in humans, it is hard to examine the direct effect of acid reflux on sleep in patients with GERD. In this paper, we show that acid reflux directly causes sleep disturbances in rats with chronic esophagitis and esomeprazole significantly improved some objective sleep parameters in Japanese GERD patients.

Effects of esomeprazole on sleep in patients with gastroesophageal reflux disease as assessed on actigraphy.

OBJECTIVE: Gastroesophageal reflux disease (GERD) is strongly associated with sleep disturbances. Although treatment with proton pump inhibitors (PPIs) helps to improve GERD symptoms and subjective sleep parameters, the effects of PPI therapy on objective sleep parameters are conflicting. The aim of this study was to examine the effects of esomeprazole treatment on GERD symptoms and sleep parameters assessed using actigraphs and questionnaires. METHODS: Thirteen patients with GERD received 20 mg of esomeprazole once daily for two weeks. The patients wore actigraphs from three days before the initiation of PPI treatment to the end of therapy. They were also asked to answer the following self-reported questionnaires: Frequency Scale for the Symptoms of GERD (FSSG), Pittsburg Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). Objective sleep parameters were evaluated using actigraphy. RESULTS: Treatment with esomeprazole significantly decreased the total FSSG score, including the scores for reflux and dysmotility, as well as the ESS score, although it had no effect on the PSQI score. After the second week of treatment, esomeprazole significantly decreased the wake time (from 47.5±39.6 min to 36.0±27.1 min) and sleep latency period (from 19.5±19.8 min to 9.9±10.2 min) and increased the percentage of sleep time (from 89.1±8.8% to 91.9±6.3%); however, improvements were not noted in all objective parameters. CONCLUSION: Esomeprazole treatment significantly improves various objective sleep parameters in Japanese patients with GERD. Further placebo-controlled randomized trials are needed to obtain detailed results.

[Management of secondary normal pressure hydrocephalus and assessment of cortical reorganization using fMRI].

We assessed the motor recovery and cortical reorganization associated with intracranial pressure (ICP) control in a secondary normal pressure hydrocephalus (sNPH) patient. A 32-year-old man with sNPH resulting from a head injury presented with left hemiplegia. A ventricular-peritoneum shunt (VP shunt) was surgically inserted for the sNPH using a Codman Hakim Programmable Valve, and his ICP was controlled according to the ventricular size by CT scanning. The motor function of the patient was evaluated by functional MRI (fMRI) during ICP control in our hospital. The fMRI was performed at 3.0 T with timed dorsal flexion-extension movement of the foot. After 3 months of shunt valve pressure control, the primary sensorimotor cortex (SM1) was activated during the affected (left) foot movement, an area that had not been able to be activated just after admission. His walking ability also recovered markedly to the point of free independent walking. The motor function of the affected lower extremity appeared to recover to almost the some degree the original motor area after control of the ICP. This finding may reflect functional reorganization of the motor pathway following ICP normalization.

Sitting balance as an early predictor of functional improvement in association with depressive symptoms in stroke patients.

The aim of the present study was to assess the relationship between sitting balance at an early stage and activities of daily living (ADL) function in 452 stroke patients. The effect of sitting balance on the two core elements of depression (apathy and depressive mood) was also examined. The ability to maintain a sitting position for 10 min (10-min sitting balance) was assessed, along with ADL using the Functional Independence Measurement, and psychological status using the Zung Self-rating Depression Scale (depressive mood), Apathy Scale (apathy) and Neuropsychiatric Inventory. Proportional-hazards analysis was used to determine the independent effect of post-stroke depression on functional outcome. Comparisons between sitting balance and psychological status were performed using logistic multiple regression analysis. Cox multiple regression analysis showed that significant differences were obtained for the sitting balance (P < 0.0002) and Mini-Mental State Examination scores (P < 0.02) in all six ADL subscales, and for age in four of the six ADL subscales (Dressing-Upper Body and Dressing-Lower Body, Toileting, Walking). Kaplan-Meier survival curves for reaching independence in ADL subscales showed highly significantly differences in achievement rate and time to reach goal for each subgroup on 10-min sitting balance (with or without assistance) and on age (young, <65; elderly, >/=65 years). Ten-minute sitting balance correlated with depressive mood and apathy. A rapid and simple screening method, 10-min sitting balance was related to scores for two core depressive symptoms, lowered mood and apathy, and was predictive of post-stroke ADL outcomes in the rehabilitation unit along with age.

Depression or apathy and functional recovery after stroke.

OBJECTIVES: While depression and apathy are common after stroke, past studies have done little to examine the influence of these two symptoms on functional outcome respectively. This study was designed to examine the effect of depression or apathy on functional recovery after stroke in 237 Japanese stroke patients. METHODS: We assessed the psychological status using self-rating scales [the Zung Self-Rating Depression Scale (SDS) for depression and the Apathy Scale (AS) for apathy] and an observer-rating scale [the Neuropsychiatric Inventory (NPI)]. We assessed physical disability using the Functional Independence Measurement (FIM). Post-hoc test and multiple regression analysis were used to determine the independent effects of post-stroke depression and apathy on functional outcome. RESULTS: Depression was observed in 75 (31.6%) using SDS and 88 (40.2%) using NPI, and apathy in 95 (40.1%) using AS and 42 (19.2%) using NPI, respectively. Post-hoc test and multiple regression analysis indicated that the cognitive variable (Mini-Mental State Examination: MMSE score) and AS score, but not SDS score, correlated negatively with improvement in FIM. CONCLUSIONS: Apathy might be more frequently associated with functional abilities and likely interact with the recovery process as compared with depression after stroke.

Identification of a new family of spinocerebellar ataxia type 14 in the Japanese spinocerebellar ataxia population by the screening of PRKCG exon 4.

Spinocerebellar ataxia type 14 (SCA14) is an autosomal dominant neurodegenerative disorder characterized by cerebellar ataxia and intermittent axial myoclonus. Various mutations have been found in the PRKCG gene encoding protein kinase C gamma in SCA14 families. Most of those mutations have been found in exon 4 of the PRKCG gene. We performed polymerase chain reaction (PCR)-based screening to clarify the approximate morbidity rate of the disease in the Japanese SCA population. We screened exon 4 of the PRKCG gene in 882 SCA patients with undefined etiologies using denaturing high-performance liquid chromatography and subsequent direct sequencing. We found a novel C/T missense mutation with a Ser119-to-Phe substitution (S119F) in 2 patients and subsequently found that they belonged to the same family. This S119F mutation was not found in 259 control individuals. Further PCR-based analysis revealed an additional 5 members with the same mutation in this family. Cerebellar ataxia was manifested in 5 of those 7 members. The main symptom in 4 of the 5 affected members was pure cerebellar ataxia with late onset. They had no myoclonus, extrapyramidal signs, ophthalmoplegia, or intellectual disturbance, some of which were found in previously reported SCA families. One patient showed intractable epilepsy, severe walking disturbance, and trunk ataxia with early onset. The results of this study suggest that the frequency of SCA14 in the Japanese SCA population is very low.

Mutant protein kinase Cgamma found in spinocerebellar ataxia type 14 is susceptible to aggregation and causes cell death.

Spinocerebellar ataxia type 14 (SCA14) is an autosomal dominant neurodegenerative disease characterized by various symptoms including cerebellar ataxia. Recently, several missense mutations in the protein kinase Cgamma (gammaPKC) gene have been found in different SCA14 families. To elucidate how the mutant gammaPKC causes SCA14, we examined the molecular properties of seven mutant (H101Y, G118D, S119P, S119F, Q127R, G128D, and F643L) gammaPKCs fused with green fluorescent protein (gammaPKC-GFP). Wild-type gammaPKC-GFP was expressed ubiquitously in the cytoplasm of CHO cells, whereas mutant gammaPKC-GFP tended to aggregate in the cytoplasm. The insolubility of mutant gammaPKC-GFP to Triton X-100 was increased and correlated with the extent of aggregation. gammaPKC-GFP in the Triton-insoluble fraction was rarely phosphorylated at Thr(514), whereas gammaPKC-GFP in the Triton-soluble fraction was phosphorylated. Furthermore, the stimulation of the P2Y receptor triggered the rapid aggregation of mutant gammaPKC-GFP within 10 min after transient translocation to the plasma membrane. Overexpression of the mutant gammaPKC-GFP caused cell death that was more prominent than wild type. The cytotoxicity was exacerbated in parallel with the expression level of the mutant. These results indicate that SCA14 mutations make gammaPKC form cytoplasmic aggregates, suggesting the involvement of this property in the etiology of SCA14.
