BackgroundFalls are a major health issue in the elderly people and an important cause of bone fracture. The aim of this study was to determine the association between quadriceps muscle strength (QMS) and falls in the elderly subjects.MethodsAll eligible participants of the Amirkola Cohort Study entered the study. Data regarding demographic characteristics, clinical and laboratory examinations were provided between 2011 to 2014. Occurrence of falls during previous year was determined by interview and review of the medical records. The study patients were divided into low, moderate and high muscle strength groups according to QMS values ≥ 30, 15–30, and < 15 kg respectively). Association between muscle strength and falls was determined by using multiple logistic regression analysis with calculation of odds ratio (OR).ResultsA total 1028 participants (females, 44.3%) were analyzed and 178(17.3%) subjects experienced a fall. Individuals with falls had higher age (p = 0.001) and lower QMS value (p = 0.001). After adjustment for all clinical and demographic variables, occurrence of falls was negatively associated with QMS and positively associated with age > 70 years old. Compared to group with QMS ≥ 30 kg, the prevalence of falls in low and moderate QMS groups increased by OR = 3(95% CI, 1.78–5.05) and 2.18 (95% CI, 1.22–3.42) respectively.ConclusionThese findings indicate that older subjects with lower QMS are at greater risk of falls. These findings provide a rational for muscle strengthening exercise in older people.

Neurodegenerative diseases (NDs) are a diversity of neurological disorders characterized by the progressive degeneration of the structure and function of the central nervous system (CNS). The most common NDs are Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). Recently, many studies have investigated associations between common NDs with noncoding RNAs (ncRNAs) molecules. ncRNAs are regulatory molecules in the normal functioning of the CNS. Two of the most important ncRNAs are microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). These types of ncRNAs are involved in different biological processes including brain development, maturation, differentiation, neuronal cell specification, neurogenesis, and neurotransmission. Increasing data has demonstrated that miRNAs and lncRNAs have strong correlations with the development of NDs, particularly gene expression. Besides, ncRNAs can be introduced as new biomarkers for diagnosis and prognosis of NDs. Hence, in this review, we summarized the involvement of various miRNAs and lncRNAs in most common NDs followed by a correlation of ncRNAs dysregulation with the AD, PD, and HD.

Background and Purpose: Stroke is the second leading cause of death worldwide. The role of zinc as a contributing factor in the pathogenesis of stroke was considered.Results: This cross-sectional study on 100 stroke patients in Ayatollah Rouhani Hospital and 100 control group from cohort master plan "Ageing and health projects Amirkola was conducted. Zinc levels Serum simultaneously with other blood tests in the early hours of hospitalization. Zinc serum level was defined 70 to 120 micrograms per deciliter.Findings: The difference in mean of zinc level in patients and control group was not significant (102.6±47.7 in control group vs 100.9±35.8 in patient, p=0.7). Difference in zinc Serum level had statically significant with IHD (under70 0 cases (0), 70 to120 8 cases (24), 120 and upper24 cases (75), p=0.003) and with type of stroke (under70 (3(3.3) hemorrhagic vs 0(0) ischemic), 70 to 120(19(21) vs6 (60)), 120 and upper68 (75.6) vs4 (40), p=0.025) and also with patient and control group (under70 (3(3) in patient's vs 20(20) control group), 70 to 120(25(25) vs54 (54)), 120 and upper72 (72) vs26 (26), p<0001). In patients group 72(73.5) of cases had zinc serum level above 120. HLP difference was significant in patient and control group (50(50) in control group vs 35(35) in patients, p=0.04). Regression logistic show that IHD (p<0001, OR=30, CI=6-152), HLP (p<0001, OR=4, CI=9.09-1.85), zinc serum level (p<0001, OR=15.5, CI=4-59.8) had significant role.Conclusions: Zinc serum levels, Ischemic Heart Disease, Hyperlipidemia were most risk factor that play role in Babol stroke patients.
