Determinants of Disability in the Elderly
__Abstract__
A person who suffers disability experiences difficulty or inability in performing the basic
activities with regard to daily living. In general the risk of disability increases with age
and constitutes a common health problem among the elderly [1].1ncidence rates in the
literature for disability range from 4.6% to 46% depending on the length of follow-up
and population characteristics [1-6].
Moreover, physically disabled elderly have a higher risk of dying or being institutionalised
[7]. Maintenance of physical function, which represents the absence of disability,
has been mentioned by researchers as one of the criteria of successful aging [8]. Disability
is also to some extent inversely proportional to quality of life (Qol). The phenomenon
that still a large proportion of elderly with a disability perceive their Qol as good, which
is called the disability paradox, may be explained by the infiuence of other factors like
lower disease burden and greater levels of psychosocial resources [9].
Disability, in most cases a chronic condition, also yields economical and logistical challenges
for society. As the older persons, most likely women, caring for their impaired
spouse, become disabled themselves more people will need extended health care
comprising the use of assistive technology, professional care givers and nursing homes
Rose oil inhalation protects against formaldehyde-induced testicular damage in rats
In this experimental study, harmful effects of formaldehyde (FA) inhalation on
sperm concentration, sperm quality, serum testosterone levels and the rat testes
were investigated. In addition, the possible protective effects of rose oil against
to these harmful effects were evaluated. For this purpose, 21 albino-Wistar rats
were used. The rats in Group I were used as control group. When the rats of
Group II were exposed FA (10 ppm/1 h) for 35 days, the rats of Group III
inhalated rose oil (1 ml/1 h) after FA. The epididymal tissues were taken for
sperm analysing and the testes were removed for histological examination. In
addition, testosterone levels were determined from the blood samples.
Although the testosterone levels, the epididymal sperm concentration, and the
progressive sperm motility significantly decreased, the abnormal sperm rate
significantly increased in the Group II when compared to Group I. In the
Group III, these damages were seen less. When the rats in the Group II
compared with the control group, there were serious histological damages. In
the Group III, it was determined that the histological changes were less than
group II. It can be expressed that serious damages occurred via formaldehyde
exposure in male reproductive system and that the rose oil had protective
effects against these damages
Age, gender and disability predict future disability in older people: the Rotterdam Study
<p>Abstract</p> <p>Background</p> <p>To develop a prediction model that predicts disability in community-dwelling older people. Insight in the predictors of disability is needed to target preventive strategies for people at increased risk.</p> <p>Methods</p> <p>Data were obtained from the Rotterdam Study, including subjects of 55 years and over. Subjects who had complete data for sociodemographic factors, life style variables, health conditions, disability status at baseline and complete data for disability at follow-up were included in the analysis. Disability was expressed as a Disability Index (DI) measured with the Health Assessment Questionnaire.</p> <p>We used a multivariable polytomous logistic regression to derive a basic prediction model and an extended prediction model. Finally we developed readily applicable score charts for the calculation of outcome probabilities.</p> <p>Results</p> <p>Of the 5027 subjects included, 49% had no disability, 18% had mild disability, 16% had severe disability and 18% had deceased at follow-up after six years. The strongest predictors were age and prior disability. The contribution of other predictors was relatively small. The discriminative ability of the basic model was high; the extended model did not enhance predictive ability.</p> <p>Conclusion</p> <p>As prior disability status predicts future disability status, interventive strategies should be aimed at preventing disability in the first place.</p
Corneal biomechanical comparison of pseudoexfoliation syndrome, pseudoexfoliative glaucoma and healthy subjects
Purpose: To evaluate the differences in corneal biomechanical properties between healthy subjects and patients with pseudoexfoliation syndrome (PEX) and pseudoexfoliative glaucoma (PEXG) using the ocular response analyzer (ORA). Materials and methods: One hundred eighteen eyes of 45 healthy, 43 PEX and 30 PEXG eyes were included in to the study. Corneal biomechanical parameters measurements were obtained using ORA. The main parameters assessed were corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated pressure measurement (IOPg) and corneal compensated intraocular pressure (IOPcc). Ultrasound pachymetry was used for measurement of central corneal thickness (CCT). Results: In healthy subjects, PEX and PEXG eyes' mean CH values were 10.3±1.4, 8.2±1.4 and 6.8±1.7mmHg, respectively. The difference in mean CH between the PEXG and other two groups were statistically significant (p<0.001). Mean CRF values were 10.3±0.7, 7.9±1.6 and 7.9±1.9mmHg, in healthy subjects PEX and PEXG, respectively. The difference in mean CRF between the PEX and PEXG was not statistically significant (p=0.630), however the mean CRF was significantly higher in healthy subjects, compared to other two groups. Mean CCT were 546.3±28, 525.5±35 and 509±36µ, in healthy subjects, PEX and PEXG, respectively. The differences on CCT were also significant among the three groups (p<0.001). Conclusion: In this study, the corneal biomechanical features of subjects with PEX were found to be changed as compared to healthy controls. In these patients; CH, CRF and CCT were decreased which was more obvious in patients with PEXG in comparison to PEX patients. © 2014 Informa Healthcare USA, Inc. All rights reserved
Structure of 1-(4-methylphenylamino)-2-phenyl-1,2-ethandione-1-oxime
The crystal structure of 1-(4-methylphenylamino)-2-phenyl-1,2-ethandione-1-oxime (C15H14N2O2) has been determined by X-ray analysis. It crystallizes in the orthorhombic space group Pna21, with unit cell parameters: a = 23.516(3), b = 5.364(3), c = 21.872(3)Å, V = 2758.7(17)Å3, Dc = 1.224 g/cm3, and Z = 8. The crystal structure was solved by direct methods and refined by full-matrix least squares to a final R-value of 0.041 for 2204 observed reflections. There are two independent molecules, A and B. These molecules are linked by intermolecular O-H···N hydrogen bonds. 2003 © The Japan Society for Analytical Chemistry

Methods: ORA values were obtained from 156 eyes of subjects with type 2 DM and 74 eyes of healthy control subjects with similar age and sex. Subjects were divided into three groups: Group 1, healthy control subjects; Group 2, diabetes patients with HbA1C ≥7%; and Group 3, diabetes patients with HbA1C <7%. Corneal biomechanical parameters: corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated pressure (IOPg), and corneal-compensated intraocular pressure (IOPcc) measurements were obtained using ORA. Ultrasound pachymetry was used for measurement of central corneal thickness (CCT). Results: CH and CRF were significantly different in each of the three groups (P-values for CH respectively; Groups 1 and 2=0.008, Groups 1 and 3, and Groups 2 and 3, <0.001, and for CRF respectively; =0.002, <0.001, <0.001). CCT was significantly different between Groups 1 and 3 and Groups 2 and 3 (P<0.001) but was insignificant between Groups 1 and 2 (P=0.965). IOPcc was not different between Groups 1 and 2 (P=0.524), and Groups 2 and 3 (P=0.115), but was significantly different between Groups 1 and 3 (P=0.003). IOPg was statistically different between each of the three groups (respectively; Groups 1 and 2, P=0.015, Groups 1 and 3, and Groups 2 and 3, P<0.001). Conclusion: Both diabetes groups were affected in terms of corneal biomechanical properties when compared to healthy subjects, there was also a positive correlation between HbA1C level and intraocular pressure.
