This study investigated the cut-points to define sarcopenia using muscle quality index (MQI) in the young reference population. Methods: Fifty healthy young (20 to 29 years) and forty elderly adults (60 to 79 years) were recruited in this study. Dual-energy X-ray absorptiometry was used to assess appendicular skeletal muscle mass. Hand grip and leg dynamometers were used to measure muscle strengths in the arm and leg. Muscle quality in the arm (MQIArm, kg/kg) and leg (MQILeg, Nm/kg) were computed as muscle strength per lean mass in the arm and leg, respectively. Total muscle quality (MQITotal) was computed as the combination of MQIArm and MQILeg, while standardized muscle quality (MQIStd) was computed as the combination of z-scores in MQIArm and MQILeg. Sarcopenia was defined as ≤2 SD below from the mean values in the young reference group. Results: The cut-points for defining sarcopenia using MQIArm, MQILeg, MQITotal, and MQIStd in men were ≤8.37, ≤12.07, 22.06, and <-3.35, and in women were ≤10.09, ≤13.97, 28.22, and <-2.25, respectively. In the elderly adults, the frequencies of sarcopenia using MQIArm, MQILeg, MQITotal, and MQIStd were 15%, 27.5%, 32.5%, and 35%, respectively. Conclusion: This study establishes new values for defining sarcopenia using MQIs. The proposed new MQI cut-points may be a role in detecting sarcopenia across individual and population level.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66884798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design: An ethically approved, cross-sectional survey study conducted in a cohort of an elderly population in 2004 with follow-up in 2014. Setting: An elderly day-care center. Participants: A total of 170 men and women were randomly selected for the baseline survey (2004). Only 105 of the subjects included in the baseline study were available for the follow-up study (2014). The sample consisted of 83.2% (n=89) women and 16.8% (n=16) men with a mean±SD age of 95.8±6.2 and 71.8±5.7 years in 2014 and 2004 respectively. Measurements: Dietary intakes (24-hour recall questionnaire) were completed for a period of three non-consecutive days, including one weekend day and two week days. Other measurements included waist circumference (WC), blood pressure and fasting (>8 hours) venous blood samples that were analyzed for total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), tryglicerides (TGs) and glucose. The Friedewald formula was used to calculate LDL-C (16). Results: The prevalence of MetS was significantly (p=0.000) higher in 2014 (63.4%) compared to 2004 (48.8%). The most prominent risk factors were central obesity (85.9%), low serum HDL-C (71.0%) and high serum TG (68.1%) levels in 2004 compared to central obesity (82.5%), low serum HDL-C (94.3%) and hyperglycaemia (48.1%) in 2014. Conclusions: MetS is highly prevalent and rapidly increasing among these elderly people. A need for identifying preventative and treatment strategies to increase wellness and reduce morbidity has been highlighted by these results.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66884692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This current double-blind, placebo-controlled randomized study investigates the effects of CFB supplementation on knee discomfort during 90 days of supplementation. Purpose: To evaluate the comparative effects of once-daily and twice-daily dosing of calcium fructoborate on knee joint discomfort for ninety days. Design: 120 participants with self-reported knee discomfort were recruited and randomized into three groups (each N=40). Participants received: 108 mg CFB twice per day (CFB-G1); or, 216 mg CFB in a single dose (CFB-G2); or, placebo. Setting: Subjects were recruited through advertisement in local papers. The researchers assessed intake and within-study levels of knee discomfort by using the McGill Pain Questionnaire (MPQ) and the Western Ontario and McMaster University Arthritis Index (WOMAC). Results: 62 female and 59 male subjects completed the study. Subjects’ average age was (52.84 ± 8.19 years) and average BMI was (26.76 ± 2.50 kg/m2). Statistical differences between groups were calculated using a two-sided, two-sample t-test. Analysis of variance (ANOVA) was used to estimate within-group changes in mean WOMAC and MPQ scores as well as against the control group. When compared to placebo, CFB-G1 showed a significant decrease in reported discomfort on day 14 (P=0.02,) day 30 (P=0.003), day 60 (P<0.0001) and day 90 (P<0.0001) according to WOMAC Scores. A similar decrease was observed for CFB-G2 WOMAC Scores on day 14 (P=0.02), day 30 (P=0.0003), day 60 (P<0.0001) and day 90 (P<0.0001). When compared to placebo, the MPQ score for CFB-G1 group decreased on day 7 (P=0.002), day 14 (P=0.001), day 30 (P<0.0001), day 60 (P<0.0001) and day 90 (P<0.0001). MPQ score decreases were also observed for CFB-G2 group on day 7 (P=0.02), day 14 (P=0.01), day 30 (P<0.0001), day 60 (P<0.0001) and day 90 (P<0.0001). When comparing CFB-G1 and CFB-G2, no significant differences were observed. Importantly, no changes were observed in the WOMAC and MPQ scores within the placebo group. Conclusion: Both CFB groups showed early and significantly improved levels of knee comfort. Knee comfort continued to significantly improve throughout the duration of this 90-day study. No significant differences were observed between the once-daily and the twice–daily doses of CFB.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"1084 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66885460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to BIA reference values and healthy subjects, MCI patients had significant differences in PA (only female), BCM and ECM/BCM index. Differences were more pronounced in females compared to males. The low levels of BCM and PA suggest that MCI patients, especially of female sex, have a poor nutritional status. BIA-derived PA might be a suitable indicator, that could enhance evaluation of nutritional status in patients with cognitive decline.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66885031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the precursor to the neurotransmitter acetylcholine, choline plays an integral role in several neuronal processes, including some responsible for memory and learning. Decreased cholinergic neuronal activity is associated with brain abnormalities consistent with Alzheimer’s disease, an aging disease that disproportionately affects the elderly, and is believed to contribute to the cognitive decline experienced by Alzheimer’s disease patients, however the mechanism for this is not well understood. In this narrative review, we explore the associations between sleep disturbances, choline and the cholinergic pathway, and Alzheimer’s disease. Current research shows that the connection between sleep disturbances, choline, and Alzheimer’s disease is worth exploring in greater depth. In this review, we demonstrate there is a need for further studies to understand the mechanism through which inadequate sleep may impair the cholinergic pathway in order to guide targeted treatments for Alzheimer’s disease.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66884597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to explore the relationships between malnutrition risk and missing teeth in community-dwelling older adults. Design: This was a retrospective cross-sectional analysis of data obtained from the electronic health records of 107 patients aged 65 and older who attended an urban northeast US dental school clinic between June 1, 2015 and July 15, 2016. Odontograms and radiographs were used to identify teeth numbers and locations; malnutrition risk was calculated using the Self-Mini Nutritional Assessment (Self-MNA). Relationships between numbers of teeth and malnutrition risk were assessed using bivariate logistic regression. Results: Participants (N=107) were 72.6 years (SD=5.6) of age; 50.5% were female. Mean Self-MNA score was 12.3 (SD=2.0) reflective of normal nutrition status; 20.6% were at risk for malnutrition, 4.7% were malnourished. Greater than 87% were partially or completely edentulous. Those with 10-19 teeth had lower Self-MNA scores (mean=11.6, SD=2.5) than those with 0-9 teeth (mean=12.7, SD=1.3) or 20 or more teeth (mean=12.6, SD=1.8) and had an increased risk for malnutrition (OR=2.5, p=0.076). Conclusion: The majority of this sample of older adults were partially edentulous and of normal nutritional status. Those with 10-19 teeth were more likely to be at risk for malnutrition. Further studies are needed to examine relationships between tooth loss and malnutrition risk and the impact of impaired dentition on the eating experience in a larger sample and to inform clinical practice.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66884770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
