In osteoporotic VCFs, pulmonary cement embolism was detected in 23% of PVP sessions, developed in the distal to third-order pulmonary arteries, and was related to leakage into the inferior vena cava.

Bone marrow progenitor cells have been shown to contribute to a small proportion of cells in nonhematopoietic tissues including the brain. In the acute unilateral middle cerebral artery occlusion model in spontaneously hypertensive rats following male-to-female bone marrow transplantation, we present data suggesting that 55% more marrow-derived cells, in general, and 161% more GFAP-positive astrocytes, in particular, migrate preferentially to the ischemic cortex than to the contralateral non-isc

Stereopsis or depth perception is an awareness of the distances of objects from the observer, and binocular disparity is a necessary component of recognizing objects through stereopsis. In the past studies, patients with neurodegenerative disease (Alzheimer dementia, AD; Parkinson's disease IPD) have problems of stereopsis but they did not have actual stimulation of stereopsis. Therefore in this study, we used a 3-dimensional (3D) movie on 3D television (TV) for actual stereopsis stimulation. We

Cerebellar ataxia (hereinafter referred to as CA) designate a group of neurodegenerative disorders. CA is distinguished into a group of hereditary and non-hereditary disorders. CA shows clinically progressive features and accompanies various neurological abnormalities. However, there are very few studies and case reports in Korean patients. To estimate the prevalence rate and current status of the CA patients in Korea, we used data from the Health Insurance Review and Assessment Service (HIRAS)

AIM: The present study used a deep learning model (recurrent neural network) for testing: (i) whether social determinants are major determinants of the association among cerebrovascular disease, hearing loss and cognitive impairment in a middle-aged or older population (hypothesis 1); and (ii) whether the association among the three diseases is very strong in the middle-aged or older population (hypothesis 2). METHODS: Data came from the Korean Longitudinal Study of Aging (2014-2016), with 6060

Thrombo-embolic events, which can be increased after splenectomy in hemoglobin disorders, can cause potentially lethal complications. Although venous thrombosis has been reported, arterial strokes are rarely reported. A case of stroke in a 52-year-old patient with a previously performed splenectomy for known hemoglobin Madrid, an extremely unstable hemoglobinopathy, led us to investigate the possible causal role of splenectomy. The patient had no history of hypertension, diabetes mellitus, smoki

노인 인구의 급증과 함께 치매 문제가 중요한 이슈가 되고 있다. 본 연구에서는 치매 환자의 보호와 부양의 주체인 치매 환자 보호자들의 치매 태도가 어떻게 나타나는지를 탐색해보았다. 연구 결과 치매 환자 보호자들의 치매에 대한 태도는 5가지 유형으로 구분되었다. : 책임부담형, 애정형, 양가감정형, 측은지심형, 적극 치료형. 각 유형은 치매 및 노인에 대한 태도와 치매 치료 및 예방에 대한 태도, 치매환자 부양 및 책임 주체에 대한 생각, 간병에 대한 정서 반응에서 서로 다른 특성을 지니고 있었다. 본 연구는 기존의 연구들이 긍정-부정의 하나의 축으로 치매 태도를 탐색하던 것에서 벗어나, 치매 환자 보호자들이 치매에 대해 가지고 있는 질적으로 다른 태도 유형을 확인하였다는데 그 의의가 있다. 또한 본 연구 결과는 향후 치매 환자 보호자들에 대한 서비스와 지원, 치매 교육 등을 기획하는데 있어 중요한 기초 자료가 될 수 있을 것이라 생각된다.

Although there was no significant difference in success rates between AL and PL points, PL is likely the best entry point. Although 30 degrees medial and approximately 5 degrees upward angulation led to the highest rate of successful screw placement, the rate was only around 80%. Given the wide individual variation, we recommend that a preoperative 3-dimensional CT scan be obtained when attempting atlantooccipital transarticular screw fixation.

BACKGROUND: This study introduces a new framework based on an artificial neural network (ANN) for testing whether social determinants are major determinants of association among diabetes mellitus, visual impairment and hearing loss in a middle-aged or old population. METHODS: The data came from the Korean Longitudinal Study of Aging (2014⁻2016), with 6120 participants aged 45 years or more. The association was divided into eight categories: one category for having no disease, three categories fo
