A proportion of patients experience acute or even prolonged cognitive impairment after surgery, a condition known as postoperative cognitive dysfunction (POCD). It is characterized by impairment in different cognitive domains and neuroinflammation has been implicated as one of the inciting factors as strategies targeting inflammation tend to improve cognitive performance. Siegesbeckia Orientails L. (S. Orientails) is a common Chinese medicinal herb used for managing chronic inflammatory diseases. We investigated if pretreatment with S. Orientails before surgery confers any neuroprotective effects in postoperative animals in terms of reducing inflammation and mitigating cognitive impairment. Three-month-old male C57BL/6N mice were fed different doses of S. Orientails extract for 14 days before they underwent a laparotomy. After cognitive testing they were sacrificed on postoperative day (POD) 3. Our results showed that animals with extract pretreatment demonstrated memory improvement in a dose-dependent manner compared with control. Further, evidence for the attenuation of systemic and neuroinflammation was found in the pretreated animals, along with the inhibition of inflammatory pathways and significantly reduced tau phosphorylation in the hippocampus. Taken together, these results demonstrated a neuroprotective effect of S. Orientails in postoperative animals, indicating a therapeutic potential of S. Orientails in minimizing POCD and the possibility of utilizing this traditional Chinese medicine perioperatively.

PURPOSE: The purpose of this study was to identify factors influencing psychosocial well-being in family caregivers of patients with amyotrophic lateral sclerosis (ALS). METHODS: A descriptive correlational design was used. The transactional model of stress and coping was used to investigate the psychosocial well-being of 137 family caregivers of patients with ALS. Data were collected through self-reported questionnaires from January to November 2016. Data were analyzed using an independent t-test, one-way ANOVA, Pearson's correlation, and hierarchical multiple regression analysis with the SPSS WIN 21.0 program. RESULTS: The regression model had an adjusted R2 of .49, which indicated that meaning-focused coping, social support, ALS patient-family caregiver relationship (especially a spousal relationship), and tracheostomy were significant predictors of caregivers' psychosocial well-being. CONCLUSION: Meaning-focused coping and social support significantly influenced caregivers' psychosocial well-being. Therefore, interventions to improve caregivers' psychosocial well-being must focus on increasing meaning-focused coping and social support resources.

3.Effects of Social Capital on Subjective Health in the Community Indwelling Elderly
Journal of Korean Academy of Community Health Nursing 2018;29(2):184-193
PURPOSE: The aim of this study is to examine a path model on the relationship among social capital, physical activity and subjective health status in the community indwelling elderly. METHODS: The study was conducted utilizing the 2014 Seoul Survey, in the method of analyzing cross-sectional design and secondary data. Among 45,497 participants in total, the data of 4578 adults aged 65 or above was analyzed. Social capital was measured by social trust and social participation. Physical activity was measured by regular exercise. Additionally, a numerical rating scale was used to assess subjective health status. The data were analyzed using descriptive statistics, Pearson's correlation coefficients and path analysis. RESULTS: Social participation and physical activity showed a direct effect on subjective health status in community indwelling elderly while social trust and physical activity showed an indirect effect on their subjective health status. The hypothetical path model of community indwelling elderly's subjective health status was proved correct. CONCLUSION: Findings from this study indicate that health-promoting intervention for community indwelling elderly should consider social trust and participation.

BACKGROUND/AIMS: Because there is a lack of effective biomarkers, we aimed to discover proteomic candidate markers for hepatocellular carcinoma (HCC) in cirrhotic patients at the highest-risk of HCC, and to validate the markers. METHODS: We collected tumor tissue from 5 cirrhotics with HCC, and from 5 cirrhotics without HCC, who underwent liver resection or transplantation. These tissue samples were analyzed by 2-dimensional difference gel electrophoresis coupled with matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and potential markers were validated at the transcriptional and translational levels. We also performed western blot assays using other blood samples from 10 cirrhotics with HCC and 10 without HCC. RESULTS: Among the 66 distinguishable spots on 2-D gel images, we identified 15 proteins overexpressed more than 1.5 fold in terms of volume ratio in the tumors. Ten of the over-expressed proteins were identified by MALDI-TOF MS; of those, only methionine adenosyltransferase 1 (MAT1), a protein specific for liver, and acyl-CoA dehydrogenase were significantly up-regulated in tumors in further immunoblotting analyses (Ps<0.05). There was no between-pair difference in MAT1 mRNA measured by real-time polymerase chain reaction (P=0.96). However, in western blots of serum samples, distinct MAT1 bands were observed in all 10 HCC patients, but in only 2 of the non-HCC patients. CONCLUSIONS: MAT1 is a potential marker for surveillance in cirrhotic patients with and without prior HCC.

OBJECTIVE: Sleep disturbance is common in the elderly, which is result from multi-factorial causes encompassing socio-demographic, behavioral, and clinical factors. We aimed to identify factors associated with insomnia among the elderly in a rural community in South Korea, a country with a rapidly growing aged population. METHODS: This cross-sectional study used the data from the second wave of the Korean Social life, Health and Ageing Project, which is a cohort study of individuals living in a typical rural community in South Korea. Socio-demographic, behavioral, and clinical characteristics were obtained through face-to-face interviews. Various factors suspected to be associated with insomnia were compared between elderly participants with and without insomnia, and multiple logistic regression analyses were conducted to identify independent risk factors for insomnia. RESULTS: We found that 32.4% of 509 participants (72.8±7.7 years old) had insomnia. Female sex [odds ratio (OR)=2.19], low education level (OR=2.44), current smoking (OR=2.26), number of chronic diseases (OR=2.21 for 2–3 chronic diseases; OR=2.06 for 4 or more chronic diseases), and depression (OR=2.53) were independently associated with insomnia. CONCLUSION: We found that sex, education, chronic disease, and depression independently increase the risk of insomnia of the elderly in a Korean rural community. To overcome the elderly's insomnia, interventions should target modifiable factors such as depression. To promote active aging, longitudinal studies of factors associated with insomnia among the elderly should be performed in different regions and communities.

PURPOSE: The aims of this study were to investigate the prevalence of upper tract involvement in ketamine-associated uropathy, and to determine the predictors of hydronephrosis in patients with a history of ketamine abuse. METHODS: This was a cross-sectional study of a prospective cohort of patients with ketamine-associated uropathy. Data including demographics, pattern of ketamine abuse, pelvic pain and urgency or frequency (PUF) symptom score, uroflowmetry (UFM) parameters, serum renal function, and liver function tests were collected. Upon consultation, ultrasonography was performed to assess the function of the urinary system. RESULTS: From December 2011 to October 2015, we treated 572 patients with ketamine-associated uropathy. Of these patients, 207 (36.2%) had managed to achieve abstinence at the time of their first consultation. Ninety-six patients (16.8%) in the cohort were found to have hydronephrosis on ultrasonography. Univariate analysis identified age, duration of ketamine abuse, PUF symptom score, voided volume on UFM, serum creatinine levels >100 μmol/L, and an abnormal serum liver enzyme profile as factors associated with hydronephrosis. Logistic regression revealed the following parameters to be statistically related to hydronephrosis: age (adjusted odds ratio [OR], 1.090; 95% confidence interval [CI], 1.020–1.166; P=0.012), functional bladder capacity (adjusted OR, 0.997; 95% CI, 0.995–0.999; P=0.029), serum creatinine >100 μmol/L (adjusted OR, 3.107; 95% CI, 1.238–7.794; P=0.016, and an abnormal serum liver enzyme profile (adjusted OR, 1.967; 95% CI, 1.213–3.187; P=0.006). CONCLUSIONS: Ketamine-associated uropathy can involve the upper urinary tract. Patient demographics as well as investigations of UFM, renal function tests, and liver function tests may allow us to identify at-risk patients.

BACKGROUND: Malnutrition is common in elderly patients with cancer and is associated with many adverse clinical outcomes, including longer length of hospital stay (LOS), muscle loss, and various postsurgical complications. In particular, elderly patients with hepatocellular carcinoma have a high risk for malnutrition, which is associated with mortality and reduced quality of life. Therefore, we evaluated the association between nutritional status and the LOS after hepatectomy for the treatment of hepatocellular carcinoma in elderly patients. METHODS: A retrospective study was conducted on 66 patients aged ≥65 years admitted consecutively from January 2010 to December 2014 for elective surgery to treat hepatocellular carcinoma. The Geriatric Nutritional Risk Index (GNRI) was applied for the assessment of nutritional risk in hospitalized elderly patients before surgery. RESULTS: The association between several factors that have been identified to influence outcomes and the LOS were evaluated by using multiple regression analysis. We found that only the GNRI was associated with the LOS. CONCLUSION: Our study shows that identifying nutritional risk using the GNRI before elective surgery is associated with increased risk of prolonged LOS. Therefore, prospective research based on GNRI can serve as a valuable resource for evaluating nutritional status of elderly patients under various clinical circumstances. Moreover, this particular research allows us to establish new ways of reducing the length of hospital stay for patients who underwent hepatic resection.

PURPOSE: This study was designed to evaluate the clinical and radiographical results of anatomical reconstruction by Chen method for chronic lateral ankle instability. MATERIALS AND METHODS: Fifteen patients with chronic lateral ankle instability who had undergone anatomical reconstruction of anterior talofibular and calcaneofibular ligaments by Chen method were evaluated retrospectively. Average age of the patients was 31.3 years, and average follow-up period was 15.5 months. Preoperative and postoperative radiographs including varus stress view and magnetic resonance imaging (MRI) were analyzed. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society (AOFAS) scale. RESULTS: Radiographically average talar tilt angle was 15.3degrees preoperatively, and the difference with contralateral normal side was 10.1degrees. At last follow up, talar tile angle and the difference with contralateral side improved to 5.9degrees and 1.3degrees respectively. AOFAS scale was 66.6 preoperatively and 87.3 postoperatively. In MRI findings, four patients had associated intra-articular lesion such as articular cartilage defect, synovitis and osteoarthritis. The talar tilt angle improvement and AOFAS scale of patients without intra-articular lesion was better than those of four patients with intra-articular lesions. Surgical wound pain occurred in six patients and sural neuropathy in three patients. CONCLUSION: The anatomical reconstruction by Chen method was an easy and effective procedure for symptomatic chronic lateral ankle instability. Careful operative technique may prevent the surgical wound pain and sural neuropathy.

PURPOSE: This study was designed to determine the quantitative changes of the numbers of the mechanoreceptors in the experimentally tenotomized Achilles tendon of rabbits as compared with short-term immobilization and long-term immobilization. MATERIALS AND METHODS: 14 white rabbits were used. After tenotomizing the right Achilles tendon, the subjects were divided into 2 groups according to the periods of immobilizaton. The left side of each Achilles tendon of the rabbits were used as controls. The tendons were stained with a modified gold-chloride method. RESULTS: The number of mechanoreceptor was significantly decreased in the tenotomized Achilles tendon group than the control group (p<0.01). There was no statistical difference between the two experimental groups in the numbers of the mechanoreceptors (p>0.01). CONCLUSION: The injured Achilles tendons may more vulnerable to injury because of the decreased numbers of mechanoreceptors, but no difference between the periods of immobilization. It may suggest that post-operative immobilization period may not affect on the outcome of operative treatment from the viewpoint of mechanoreceptors.
