The Concept of Successful Aging: A Review Article

Background With the increasing number of elderly people in the world, usage of concepts and terminology related to this phenomenon has substantially increased. One concept in this context is successful aging. The purpose of the present study is to extract and introduce a common concept to be used in studies on measuring successful aging. Methods This is a review study. First, by searching the databases of Magiran, Noormags, Medlib, Irandoc, Iranmedex, Barakat Knowledge Network System, Civilica, SID, ISI Web Of Science, PubMed, Scopus, Science Direct and search engines, Google Scholar and Elmnet as well as using standard keywords such as elder, elderly, aging, and successful aging, all related published articles during the period 1995 to 2017 were retrieved. A total of 3417 documents were retrieved. By removing 3390 unrelated, duplicate and unusable documents, 27 articles were included in the study after quality control. Results The findings of the study were categorized in three areas: “defining successful aging by focusing on dimensions”, “successful aging principles” and “factors influencing successful aging”. Reviewing various studies, we found that the definition of successful aging deals with cognitive action, perception, control, life satisfaction, and ethics. Successful aging is also defined as having inner feelings of happiness and satisfaction with life for the present and the past. Sometimes successful aging is also considered to be survival with health. Conclusion Health care professionals as community health supporters can use the results from the present study for providing the grounds for successful aging. Then, they can use the designed successful aging program for preserving and promoting active and healthy aging for every elderly person in old age.
Predictors of unfavourable outcome in aneurysmal subarachnoid haemorrhage.

BACKGROUND Mortality rates following aneurysmal subarachnoid haemorrhage (aSAH) have decreased due to improvements in diagnoses and the management of complications, as well as early obliteration of the aneurysms. Neurogenic pulmonary oedema (NPO) is a clinical syndrome associated with an acute increase in intracranial pressure and a release of catecholamines into the circulation. This study investigated independent predictors of unfavourable outcomes (Glasgow Outcome Scores 1, 2 or 3) in patients with aSAH. MATERIALS AND METHODS A total of 262 patients with aSAH (162 females) were included in this prospective study. Clinical characteristics were assessed, and electrocardiographic, serum cardiac and inflammatory biomarker measurements were recorded on admission. Outcomes were assessed three months after admission. Univariate and multivariate analyses of these data were used to predict unfavourable outcomes. RESULTS A total of 156 patients (59.54%) had unfavourable outcomes. Compared to those who had favourable outcomes, patients with unfavourable outcomes were significantly older (54.37 ± 10.56 vs. 49.13 ± 10.77 years; p < 0.001) and had more severe aSAHs (Hunt and Hess grades ≥ 3: 82.7% vs. 39.6%; p < 0.001). Patients with unfavourable outcomes were more likely to have NPO (10.3% vs. 2.8%; p = 0.023), hydrocephalus (34.0% vs. 20.8%; p = 0.02), and aneurysm reruptures (28.2% vs. 3.8%; p < 0.001). Independent predictors of an unfavourable outcome included Hunt and Hess grades ≥ 3 (odds ratio [OR], 4.291; 95% confidence interval [CI], 2.168-8.491; p < 0.001), increased systolic blood pressure on admission (OR, 1.020; 95% CI, 1.002-1.038; p = 0.03), increased heart rate (HR) on admission (OR, 1.024; 95% CI, 1.001-1.048; p = 0.04), and aneurysm rerupture (OR, 4.961; 95% CI, 1.461-16.845; p = 0.01). CONCLUSIONS These findings suggest that aneurysm reruptures, as well as increased blood pressure and HR, are associated with unfavourable outcomes in patients with aSAH.
Genetic characterization of 15 autosomal STRs in the interior Sindhi population of Pakistan and their phylogenetic relationship with other populations

Genetic structure of a population can be influenced by evolutionary processes and cultural histories which can alter the frequencies of different variants at particular genetic markers. These characteristics make DNA evidence suitable for forensic applications. Little relevant data are available from the interior Sindhi population; thus, in the current study, we have investigated 15 autosomal STRs in 181 unrelated individuals belonging to the interior parts of Sindh Pakistan, to establish its lineage and parameters of forensic interest. These STRs revealed a high power of discrimination (CPD), power of exclusion (CPE) and matching probability (CMP) are 0.9999999999999999968997, 0.99998612 and 3.1003 × 10–18 respectively. The genetic distances, neighbour‐joining (NJ) tree, interactivity test and principal component analysis (PCA) based on 15 autosomal STR loci showed that the interior Sindhi population had a closer genetic relationship with Pakistani populations and distant relationships with regional (India and Afghanistan) populations. The present findings exhibited that STRs included in AmpFLSTR Identifiler kit (Applied Biosystems) are genetically polymorphic in the interior Sindhi population of Pakistan. This study provides valuable population genetic data for the genetic information study, forensic human individual identification and paternity testing.
Development of a dyadic sleep intervention for Alzheimer’s disease patients and their caregivers

Abstract Purpose This study aimed to refine a behavioral sleep intervention program targeting patients with Alzheimer’s disease and their caregivers. Methods In this case series, key components of the sleep program were built upon previous intervention studies of patients with cognitive impairment/dementia. The intervention consisted of five weekly sessions covering sleep hygiene, sleep compression, stimulus control, daily walking/light exposure, relaxation/mindfulness, and caregiver training to manage patients’ behavioral problems. The materials and structure were iteratively refined based on feedback from caregivers and sleep educators. Sleep diaries were used to evaluate sleep outcomes. Results Five out of six enrolled dyads completed the sessions. Several revisions were made during testing: the last session was changed from telephone to in-person; some components (e.g., sleep scheduling, mindfulness) were rearranged within or across sessions; sleep educator guidelines for sleep scheduling, light exposure, and walking were revised. After the fifth dyad, no additional issues were identified by the caregiver or the sleep educator. Four patients and three caregivers had improved sleep at the last session. Conclusions The iterative refinement process was successful in finalizing the intervention program, with evidence of sleep improvements. Formal pilot testing of the program will provide further information on feasibility and effectiveness. IMPLICATIONS FOR REHABILITATION Our dyadic behavioral sleep program can be tailored to various types of sleep problems among patients with Alzheimer’s disease and their family caregivers, with the goal of improving daytime function by reducing sleep disturbances at night. Caregiver training and participation of both members of the dyad in sleep management may benefit the patients’ sleep and other health outcomes, reduce caregiver stress and burden, and ultimately delay or prevent institutionalization of Alzheimer’s disease patients.
Gedanken Tests for Correlated Michelson Interferom- eters

The features of correlated Michelson interferometers are for describing the analysis of Einsteinian spacetime models, and the quantum geometries pertinent with descriptions of GR compatible with particle Physics. Such apparati allow for the spectral decomposition of fractional Planck-scale displacements correlations and fractional Plancktime-interval correlations for kinematical investigations in particle Physics on emerging Minkowski background, and for models which admit GR as a limit after cosmological implementations for Poincaré particles content. Keywords—interferometers; general relativity; theory of gravitation; fractional-powers spectral analtsys; relativistic symmetris
Pipeline Flex Embolization Device (PED Flex) for the treatment of intracranial aneurysms: Periprocedural outcomes and first-year angiographic results

Background/aim The Pipeline Flex Embolization Device (PED Flex) is a new updated version of the PED classic that incorporates a new delivery system to allow facilitation of stent deployment, resheathing, and removal of the capture coil. This study evaluated the PED Flex in terms of the technical aspects of the procedure and first-year follow-up results. Materials and methods This retrospective study involved prospectively collected data from May 2015 to August 2017. The primary endpoint was technical aspects of the procedure, and the secondary endpoint was first-year follow-up results. Results Forty-nine patients with 59 target intracranial aneurysms were enrolled. Patients’ mean age was 52 years (range 21−71 years), and 31 (63.0%) were female. All aneurysms except for three were unruptured. The mean aneurysm diameter was 8 mm. Forty-seven patients with 56 aneurysms were successfully treated. Due to advancement, repositioning, and migration problems, 8 (13.1%) stents were not deployed and discharged. The total aneurysm occlusion rate was 77.0%. The mortality rate was 4.3%. Conclusion Our experience shows that the applicability and safety of the renewed delivery system provided by PED Flex for improving device apposition and opening has been proven with one-year angiographic and clinical follow-up results.
Alcohol-based mouthwash as a risk factor of oral cancer: A systematic review

Background Oral and pharynx cancer represent a serious global problem, reaching an incidence of half a million cases annually. The role of tobacco and alcohol have been studied and proven to be one of its risk factors. We also know that mouthwashes contain a variable percentage of alcohol, so there is a reasonable concern about their role in carcinogenesis. Material and Methods To answer the PICOS (Population; Intervention; Comparison; Outcomes; Study) question: "Do patients (Population) who use alcohol-based mouthwashes (Intervention) compared to those who do not use them (Comparison) have higher acetaldehyde levels in saliva or higher risk of oral cancer development? (Outcomes)" Meta-analyses, systematic reviews, randomized and non-randomized clinical trials, case-control studies, and prospective and retrospective cohort studies were included (Study). Two independent authors conducted literature screening through MEDLINE, Scopus and the Cochrane Library, and they also conducted article and data extraction to undertake quality analyses. The main outcome measures were salivary acetaldehyde levels or the risk of oral cancer development. The most relevant data was extracted and the risk of bias from the studies included was also evaluated. Results Out of 497 potentially eligible papers, 8 studies were included in the qualitative analysis which include a total of 43,499 subjects: two meta-analyses, a clinical trial, three case-control studies and two cohort studies. One study (n = 3,926) found a relationship between alcohol mouthwash and oral cancer, two studies (n = 25,033) found this relationship when a high frequency of mouthwash was present, three studies (n = 14,482) failed to find this relationship and 2 studies (n = 58) found a temporary increase of acetaldehyde levels in saliva after alcohol mouthwash. Conclusions It cannot be guaranteed that the use of mouthwash represents an independent risk factor for the development of head and neck cancer. However, the risk does increase when it occurs in association with other carcinogenic risk factors. Key words:Oral Cancer, Oropharyngeal Neoplasms, Mouthwashes, Mouth rinse, Ethanol, Acetaldehyde, alcohol.
Clinical glycomics in the diagnostic laboratory.

Glycosylation is the most diverse type of protein modifications. Glycosylation occurs in the endoplasmatic reticulum (ER) and Golgi apparatus. The presence of multiple competing glycosyltransferases and glycosidases results in a highly heterogeneous population of glycan structures on each protein.
Assessment of the visual pathways in patients with neurofibromatosis-1 by 3S-space technique with 3-Tesla MRI

Background/aim We aimed to evaluate the size/tortuosity of the optic nerve (ON) and the dilatation of the ON sheath (ONS) in neurofibromatosis type 1 (NF-1) patients with 3T-MRI, and to assess the usefulness of 3D-SPACE in imaging the optic pathway, ON, and ONS in NF-1 patients. Materials and methods Twenty consecutive NF-1 patients without optic pathway glioma (OPG) (Group 1), 16 consecutive NF-1 patients with OPG (Group 2), and 19 controls were included in this study. The thickness and tortuosity of the ON and the diameter of the ONS were measured on STIR and 3D-SPACE images. Results The thickness of the ON was similar in all groups on STIR images (P>0.05). The mean ONS diameter was higher in Group 2 with this sequence (P=0.009). Controls had significantly lower grades of ON tortuosity than Groups 1 and 2 (P=0.001), and Group 1 had significantly lower ON tortuosity compared to Group 2 (P=0.001). Severe tortuosity was only detected in Group 2. Conclusion ON tortuosity and ONS diameter were increased in NF-1 patients in the presence of OPG. High-resolution cranium imaging with the 3D-SPACE technique using 3T-MRI seems to be helpful for detection of the optic pathway morphology and pathologies in NF-1 patients.
Correlation and Characteristics of Intravoxel Incoherent Motion and Arterial Spin Labeling Techniques Versus Multiple Parameters Obtained on Dynamic Susceptibility Contrast Perfusion MRI for Brain Tumors.

Purpose : To compare data on brain tumors derived from intravoxel incoherent motion (IVIM) and arterial spin labeling (ASL) imaging with multiple parameters obtained on dynamic susceptibility contrast (DSC) perfusion MRI and to clarify the characteristics of IVIM and ASL perfusion data from the viewpoint of cerebral blood flow (CBF) analysis. Methods : ASL-CBF and IVIM techniques as well as DSC examination were performed in 24 patients with brain tumors. The IVIM data were analyzed with the two models. The relative blood flow (rBF), relative blood volume (rBV) corrected relative blood volume (crBV), mean transit time (MTT), and leakage coefficient (K2) were obtained from the DSC MRI data. Results : The ASL-CBF had the same tendency as the perfusion parameters derived from the DSC data, but the permeability from the vessels had less of an effect on the ASL-CBF. The diffusion coefficient of the fast component on IVIM contained more information on permeability than the f value. Conclusion : ASL-CBF is more suitable for the evaluation of perfusion in brain tumors than IVIM parameters. ASL-CBF and IVIM techniques should be carefully selected and the biological significance of each parameter should be understood for the correct comprehension of the pathological status of brain tumors.

Spectral Decomposition and Reconstruction of Nuclear Plant Signals

A reactor parameter simulation system (RPSS) has been developed in SAS" with the pwpose of analyzing serially· correlated signals, decomposing those signais into deterministic and stochastic components, and reconstructing new signals that possess the same correlation structure as the original signals. The RPSS provides (I) a simulation tool for plant control strategy development, and for safetystudy investigations of transient events (such as a degraded sensor) and (2) a vehicle for filtering serial correlation from reactor signals, which is important in our ongoing development of expert systems for sensor-operability surveillance. The power and utility of theRPSS is demonstrated on signals from ANL's EBR-II nuclear reactor and verified through various statistical tests.
S100B and delirium in the geriatric acute care setting

Delirium and its relation to biochemical markers have been considered a study question in several research works. The relation between S100B levels and delirium is still a matter of discussion. Objective: To compare the serum level of S100B in patients with and without delirium and to detect the relation between S100B and delirium subtypes. Method: A case control study was conducted on 114 elderly (60 years and older) selected from the geriatric acute care unit at Ain Shams University Hospitals. They were classified into two groups; 58 elderly cases who had delirium diagnosed by Confusion Assessment Method and 56 controls. Then delirium was reclassified according to the subtypes of delirium into Hyperactive: 46 patients, hypoactive: 2 patients, and Mixed: 10 patients. Serum S100B levels were determined by ELISA. Results: Cases were significantly older than controls (72.4 ± 9.4 versus 66.9 ± 5.3 years respectively) (P < 0.001). S100B levels were higher in cases (32.4 ± 9.8 pg/ml) than controls (30 ± 9.3 pg/ml) but the difference was not statistically significant (P = 0.19). There was no significant difference in S100B levels between the different subtypes of delirium. Conclusion: Delirious patients had higher S100B levels than controls but the difference was not statistically significant.
Water-soluble nitroxyl porphyrin complexes FeIITPPSHNO and FeIITPPSNO- obtained from isolated FeIITPPSNO•.

The first biomimetic water soluble FeII-porphyrin nitroxyl complexes were obtained and characterized by UV-Vis in protonated and deprotonated forms by reduction of previously isolated and characterized FeIITPPSNO•. The pKa involved in the FeII-HNO ⇄ FeII-NO- + H+ equilibrium was estimated to be around 9.7. The FeIITPPSHNO complex spontaneously reoxidizes to the nitrosyl form following a first order kinetic decay with a measured kinetic constant of k = 0.017 s-1. Experiments show that the HNO adduct undergoes unimolecular homolytic cleavage of the H-NO bond. DFT calculations suggest a phlorin radical intermediate for this reaction. The deprotonated NO- complex resulted more stable, with a half-life of about 10 minutes.
Principles and current trends in the correlative evaluation of glioma by advanced MRI techniques and PET.

Cerebral gliomas comprise a heterogeneous group of primary neoplasms of the central nervous system, representing a significant cause of cancer morbidity and mortality. Contrast-enhanced magnetic resonance imaging (MRI) is paramount for identifying structural brain abnormalities related to the development of gliomas. Although morphological MRI remains the current standard of care for initial diagnostic workup, surgical planning, monitoring therapy response and surveillance during follow-up, it is rather difficult to define tumor grade and boundaries and to assess response to radiochemotherapy solely by contrast-enhancement, due to a variety of factors influencing blood-brain barrier (BBB) permeability and contrast agent distribution. The nature of a lesion lies beyond often misleading gross structural patterns, down to the cellular and molecular level, hence the imaging techniques of advanced multimodal MRI and positron emission tomography (PET) have emerged to provide a critical non-invasive insight into the underlying biology of primary brain cancer. Out of the various PET radiotracers, labeled amino acids are of particular significance due to their non-dependency on BBB disruption to reach glioma cells and their excellent tumor-to-background contrast. After discussing the basic imaging principles of MR perfusion, diffusion, spectroscopy and PET in glioma, this review focuses on the correlative imaging with amino acid PET and advanced MRI techniques in tumor grading and staging, in guiding stereotactic biopsy and surgical excision and in assessing therapy response, post-therapy surveillance and prognosis. Lastly, a reference is made on the expanding availability of integrated PET-MRI systems and the resulting benefits of simultaneous image acquisition.
Protein Translational Diffusion and Intermolecular Interactions of Globular and Intrinsically Unstructured Proteins.

The study of intermolecular interactions of proteins has been an important problem for many years. The paper presents the approach to analyze different levels of protein interactions in solutions through the set of the second and higher-order virial coefficients. The proposed approach is based on the diversified analysis of protein translational collective diffusion and self-diffusion obtained by the dynamic light scattering (DLS) and the pulsed-field gradient NMR (PFG NMR) spectroscopy experimental data. The experimental results were analyzed within the theoretical approach based on the Vink's frictional formalism of nonequilibrium thermodynamics and the standard DLVO theory of interactions of colloid particles in electrolyte solutions. The second and the higher order virial coefficients were obtained to estimate the pairwise and many-body intermolecular interactions in the solutions of globular α-chymotrypsin and intrinsically unstructured αS-casein. The second virial coefficients were calculated from the model of the protein - protein potential of mean force. The description of protein - protein interactions includes the set of interaction potentials: the attractive charge - dipole, dipole - dipole, the dispersion Hamaker, the mean force osmotic-attraction and the repulsive charge-charge ones. It has been found that the major contribution to the intermolecular αS-casein interactions is made by the repulsive charge - charge potential, whereas for the case of α-chymotrypsin the contributions from other types of interaction are of importance. It was determined that the model was well suited to describe the interactions of both globular and intrinsically disordered proteins. The suggested combination of the Vink's approach and the DLVO theory is novel and holds much promise to make profound analysis of processes in systems containing various types of protein molecules.
Quantitative Particle Uptake by Cells as Analyzed by Different Methods
