PURPOSE: The purpose of this study was to evaluate the effects of reminiscence therapy on depressive symptoms in older adults with dementia using a systematic review and meta-analysis. METHODS: Randomized controlled trials (RCTs) published from January 2000 to January 2018 were searched through Research Information Sharing Service (RISS), Korean Studies Information Service System (KISS), Korean Medical Database (KMbase), KoreaMed, PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Ovid MEDLINE. Two researchers independently performed the search, selection, and coding. Comprehensive Meta-Analysis 3.0 was used for meta-analysis, and Review Manager program 5.3 was used for quality assessment. RESULTS: Out of the 1,250 retrieved articles, 22 RCTs were selected for analysis. The overall effect size of reminiscence therapy for mitigating depressive symptoms in older adults with dementia was −0.62 (95% Cl: −0.92 to −0.31). The effect size was greater in older adults under 80, those with less disease severity, and those for whom the therapy session lasted less than 40 minutes. CONCLUSION: Reminiscence therapy is an effective non-pharmacological therapy to improve depressive symptoms in older adults with dementia. Because its effectiveness is also influenced by age, disease severity, and application method, it is necessary to consider treatment designs based on individual characteristics as well as methodological approaches.

BACKGROUNDAwareness under general anesthesia is a serious complication which leads to psychiatric disorders. The incidence of awareness in patients undergoing cardiac surgery has been reported in as many as 1.5% - 23% in foreign countries. But so far, medical literature about awareness during cardiac surgery is still rare in China. Therefore, we investigated the incidence of awareness in patients undergoing different kinds of cardiac surgery, the phases when awareness occurred and the effect of cardiopulmonary bypass on the incidence of awareness in coronary artery bypass grafting in Beijing.

METHODSPatients' recall of awareness during cardiac surgery was assessed. One hundred patients undergoing coronary artery bypass grafting (CABG) in Chaoyang Hospital, Beijing, one hundred patients undergoing CABG and one hundred patients undergoing valve replacement or septal defect repair in Fuwai Hospital, Beijing, were interviewed 3-6 days after surgery. Every report about patients on recall of awareness was recorded. An independent research team, blinded to patients' surgery and anesthesia, assessed every report of awareness.

RESULTSThe incidence of awareness of patients received CABG under cardiopulmonary bypass (CPB), off -pump CABG, septal repair or valve replacement under CPB was 4.7% (5 of 106 cases), 9.6% (9 of 94 cases) and 4% (4 of 100 cases), respectively. CPB did not greatly affect the incidence of awareness during the period of CABG (P > 0.05). The incidence of awareness of patients who received CABG under CPB did not increase significantly, in comparison with that of patients who received septal repair or valve replacement under CPB in Fuwai Hospital (P > 0.05). Awareness easily occurred before bypass grafting or CPB.

CONCLUSIONSAwareness mainly occurs before bypass grafting or CPB in cardiac surgery. Most cases with awareness have auditory perceptions. CPB is not a main factor which affects the incidence of awareness of CABG. Surgical types do not affect the incidence of awareness of patients under CPB.

Many applications in virtual reality and telerobot call for the implementation of displaying the human softness haptics on the object being touched. Although there are lots of literatures on discrimination threshold for displacement, force magnitude, shape and viscosity, there is still a lack of research on remembrance of softness haptic perception in human fingertips. Such research is needed in designing haptic rendering and display system. In this paper, a novel softness haptic display device based on deformable length of elastic element control was adopted as a test device to study the human fingertip's ability of remembrance of softness haptic perception. According to the recall experiment and recognition experiment, the softness haptic memory span and reaction time were discussed. From the experimental results, some important conclusions have been obtained: (1) human softness haptic memory span is 3 to 4 items, which is smaller than visual memory span and auditory memory span; (2) it is more difficult for people to remember hard objects than soft objects.

PURPOSE: This study examined the effects of individual reminiscence therapy on older adults' depression, morale, and the quality of life. METHODS: The design was a single-group pre-test and post-test study. Subjects consisted of 31 older adults from two senior centers and a welfare center in Seoul. Individual reminiscence therapy was applied to study subjects four times, once a week for an hour at each time. Measurement tools were the Geriatric Depression Scale Short Form Korea (GDSSF-K) for depression, Mun Ae-ri's (1996) scale for morale, and Medical Outcomes Study Short Form 36 (SF-36) for the quality of life. Data was analyzed using descriptive statistics, paired t-test, and pearson correlation. RESULTS: The application of individual reminiscence therapy reduced older adults' depression (t=-5.65, p=.000), and enhanced older adults' morale (t=4.65, p=.000). The application of individual reminiscence therapy improved older adults' quality of life (t=5.00, p=.000). CONCLUSION: Findings of the study suggest that individual reminiscence therapy may be applied as a nursing intervention that contributesto the improvement of older adults' quality of life, reduces their depression, and enhances their morale.

The prefrontal cortex and hippocampus may support sequential working memory beyond episodic memory and spatial navigation. This stereoelectroencephalography (SEEG) study investigated how the dorsolateral prefrontal cortex (DLPFC) interacts with the hippocampus in the online processing of sequential information. Twenty patients with epilepsy (eight women, age 27.6 ± 8.2 years) completed a line ordering task with SEEG recordings over the DLPFC and the hippocampus. Participants showed longer thinking times and more recall errors when asked to arrange random lines clockwise (random trials) than to maintain ordered lines (ordered trials) before recalling the orientation of a particular line. First, the ordering-related increase in thinking time and recall error was associated with a transient theta power increase in the hippocampus and a sustained theta power increase in the DLPFC (3-10 Hz). In particular, the hippocampal theta power increase correlated with the memory precision of line orientation. Second, theta phase coherences between the DLPFC and hippocampus were enhanced for ordering, especially for more precisely memorized lines. Third, the theta band DLPFC → hippocampus influence was selectively enhanced for ordering, especially for more precisely memorized lines. This study suggests that theta oscillations may support DLPFC-hippocampal interactions in the online processing of sequential information.

Awareness of intraoperative events in patients under general anesthesia is rare, but awareness during anesthesia is a serious complication that leads to anxiety and post-traumatic stress disorder. The Bispectral Index (BIS) has generally been accepted as a measurement of hypnosis under anesthesia. It is derived from a processed electroencephalogram and computer algorithm that assigns a numerical value based on the probability of consciousness. A 46-year-old, 65-kg male without underlying disease underwent elective surgery for ventral hernia. The patient in this case was administered an anesthetic that we frequently use and then average BIS value are 35. But he experienced awake during general anesthesia. We describe the first case of intraoperation awake under BIS 40 using desflurane.

OBJECTIVE: To investigate the incidence of awareness during general anesthesia in patients undergoing surgery. METHODS: A total of 1,800 patients who underwent the selected and acute surgery with general anesthesia were enrolled. Brain function monitors were not used. Patients were interviewed twice during 24 h and 96 h postoperatively to determine intraoperative awareness. RESULTS: Of all the inpatients, 13 (0.72%) reported clear awareness and never forgot anything during the operation; 145 (8.1%) reported dreaming during anesthesia with doubtful intraoperative recollection. Among the 145 patients, 108(74.5%) were females and 114(78.6%) received propofol anesthesia. CONCLUSION Intraoperative recollections are rare complication of general anesthesia, and are associated with the increased ASA physical status. Age and sex do not influence the incidence of awareness. Dreaming during anesthesia is related to younger females and propofol maintenance.

OBJECTIVE: To explore the autobiographical memory characteristics in depressed patients and their influence factors. METHODS: Autobiographical memory, emotion and cognitive executive function of 60 depressed patients and 60 healthy controls were assessed with autobiographical memory test (AMT), Hamilton depression scale (HAMD), Beck depression inventory (BDI), Beck anxiety inventory (BAI), hospital anxiety and depression scale (HAD), arrow-task stroop test (ATST), Wisconsin card sorting test (WCST), Backward masking test (BMT) and continuous performance test (CPT). RESULTS: The specific memory of the depressed group was significantly less than that of the control group, and was negatively related with the negative emotion score, the time of anterograde and retrograde reading of ATST, and the time difference of ATST. The overgeneral memory increased and the latency to response of ATST was significantly longer than that of the control group. The two factors were positively related with the negative emotion score, the time of anterograde and retrograde reading of ATST, and the time difference of ATST. CONCLUSION The autobiographical memory of the depressed patients is overgeneralized and retarded. These characteristics are related with negative emotion and impairment of cognitive executive function.

PURPOSE: The purpose of this study was to identify the effects of an exercise program on frontal lobe cognitive function in seniors. METHODS: The participants were 42 seniors using a health center in Seoul (experimental group) and 28 seniors using a facility for elders in Seoul (control group). The exercise program was carried out for 16 weeks from April to August 2007. The frontal lobe cognitive function, which includes short term memory, attention, immediate memory, delayed memory, verbal fluency and motor function, was measured by the Digit Span Forward test, Trail Making test, Immediate recall words test, Delayed recall words, Controlled oral word association test and Finger tapping test. The collected data were analyzed by Fisher's exact test, Chi-square, t-test, and ANCOVA using the SAS program. RESULTS: The major findings of this study were as follows: Attention (p=.009), immediate memory (p=.005), delayed memory (p=.009), and verbal fluency (p=.004) improved after the exercise program. CONCLUSION: In this study, the exercise program was effective in improving frontal lobe cognitive function in elders. So it provides basic information for further nursing education on exercise programs which will be effective for prevention of early cognitive function decline in normally aging elders.
