    Purpose of this study is present the normal range of cardiac size and cardiothoracic ratio according to patient position(chest PA and AP) and age of Korean adult male on digital chest X - ray, And to propose a mutually compatible conversion rate. 1,024 males were eligible for this study, among 1,300 normal chest patients who underwent chest PA and low-dose CT examinations on the same day at the 'S' Hospital Health Examination Center in Seoul From January to December 2014. CS and CTR were measured by Danzer (1919). The mean difference between CS and CTR was statistically significant (p<0.01) in Chest PA (CS 135.48 mm, CTR 43.99%) and Chest AP image (CS 155.96 mm, CTR 51.75%). There was no statistically significant difference between left and right heart in chest PA and AP images(p>0.05). CS showed statistically significant difference between Chest PA (p>0. 05) and Chest AP (p<0.05). The thorax size and CTR were statistically significant (p<0.01) in both age and chest PA and AP. Result of this study, On Chest AP image CS was magnified 15%, CTR was magnified 17% compare with Chest PA image. CS and CTR were about 10% difference by changing posture at all ages.

    We aimed to evaluate the interest of adult inpatients and selected outpatients in engaging in a large, real-life, hospital-based, genomic medicine research project and in receiving clinically actionable incidental findings. Within the framework of the cross-sectional Institutional Biobank of Lausanne, Switzerland, a total of 25721 patients of the CHUV University Hospital were systematically invited to grant researchers access to their biomedical data and to donate blood for future analyses, including whole-genome sequencing. Multivariable logistic regression analysis was used to identify personal factors, including age, gender, religion, ethnicity, citizenship, education level and mode of admission, associated with willingness to participate in this genomic research project and with interest in receiving clinically actionable incidental findings. The overall participation rate was 79% (20343/25721). Participation rate declined progressively with age, averaging 83%, 75%, 67% and 62% in patients aged rate, but not with higher willingness to receive incidental findings within the population who had agreed to participate. A large proportion of adult patients, even among the elderly, are willing to actively participate and receive incidental findings in this systematic hospital-based precision and genomic medicine research program with broad consent.

    Various disciplines focus on a multiplicity of aspects of aging: lifestyles, personal biological factors, psychological conditions, health conditions, physical environment, and social and economic factors. The aforementioned are all related to the determinants of active aging. The aim is to describe the development of a middle-range theory based on coping and adaptation with active aging. Concepts and relationships derived from Roy's model of adaptation are included. The proposed concepts are hope, health habits, coping with aging, social relations, and active aging.

    Single photon emission computed tomography (SPECT) using {sup 99m}Tc-HMDP was performed on 53 middle-aged or elderly patients (male 20, female, 33; age range, 40-80 years old) with lumbago, i.e., 25 patients with lumbar spondylosis, 15 with lumbar degenerative spondylolisthesis, 4 with spondylolytic spondylolisthesis, 3 with compression fracture, 3 with pulurent spondylitis, 2 with spondylous osteoporosis, and 1 with spinal osteodesmosis. {sup 99m}Tc-HMDP (740 MBq) was intravenously injected and regular SPECT was performed at 3 hours. Gamma camera was performed for about 10 seconds with 5deg intervals, and 36 steps (180deg) of collection was completed after about 6 minutes. The radioisotope accumulation, the presence or absence of sthenia, and its site were evaluated. Forty-seven (88.7%) patients showed excessive accumulation, i.e., 40 (75.5%) in peripheral vertebral osteophyte, 31 (58.5%) in vertebral articulations, and 10 (18.9%) in whole vertebral body. Significantly increased bilateral excessive accumulation was admitted in the vertebral articulations of sliding disc in degenerative spondylolisthesis. SPECT is considered useful in understanding the pathophysiology of degenerative lumber diseases. (S.Y.).

    Patients are living longer and the rate of edentulism is decreasing. Endodontic treatment is an essential part of maintaining the health and well-being of the elderly. Retention of natural teeth improves the quality of life and the overall health and longevity of ageing patients. Also, teeth that might be otherwise extracted may be strategically valuable to retain a prosthesis, and elderly patients are more likely to have medical complications that may prevent dental extractions from being safely performed. The technical goals of endodontic treatment in the elderly are the same as those for younger patients. However, the pulpo-dentinal complex undergoes calcific changes over time, which may pose challenges for the clinician. The purposes of this review are to discuss age changes in the pulp and the challenges posed by diagnosing, treatment planning and treating the elderly endodontic patient. © 2015 Australian Dental Association.

    In order to apply the right treatment for hemostatic disorders in pediatric patients, laboratory data should be interpreted with age-appropriate reference ranges. The purpose of this study was to determining age-dependent reference range values for prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen tests, and D-dimer tests. A total of 320 volunteers were included in the study with the following ages: 1 month - 1 year (n = 52), 2 - 5 years (n = 50), 6 - 10 years (n = 48), 11 - 17 years (n = 38), and 18 - 65 years (n = 132). Each volunteer completed a survey to exclude hemostatic system disorder. Using a nonparametric method, the lower and upper limits, including 95% distribution and 90% confidence intervals, were calculated. No statistically significant differences were found between PT and aPTT values in the groups consisting of children. Thus, the reference ranges were separated into child and adult age groups. PT and aPTT values were significantly higher in the children than in the adults. Fibrinogen values in the 6 - 10 age group and the adult age group were significantly higher than in the other groups. D-dimer levels were significantly lower in those aged 2 - 17; thus, a separate reference range was established. These results support other findings related to developmental hemostasis, confirming that adult and pediatric age groups should be evaluated using different reference ranges.

    The etiopathogenesis of schizophrenia is poorly understood. Within the proposed "neurodegeneration paradigm", observations have been put forth for "accelerated aging" in this disorder. This proposition is largely based on the neuroscience research that demonstrates progressive changes in brain as well as other systemic abnormalities supportive of faster aging process in patients with this disorder. In this review, we have summarized the literature related to the concept of early aging in schizophrenia. These studies include P300 abnormalities & visual motion discrimination, neuroimaging findings, telomere dynamics as well as neuropathology of related brain regions. We also propose a role of vitamin D, neuroimmunological changes and elevated oxidative stress as well as mitochondrial dysfunction in addition to the above factors with 'vitamin-D deficiency' as the central paradox. Put together, the evidence supporting early aging in schizophrenia is compelling and this requires further systematic studies. Copyright © 2014 Elsevier B.V. All rights reserved.

    This virtual issue (VI) has been assembled to coincide with the 8th Annual Patient Information Conference 2013 organised by the UK Patient Information Forum (PiF). The conference theme 'Information and support - a service in its own right' is a response to policy documents and initiatives in both Scotland and England which signal the coming of age of patient/consumer information. The VI consists of a collection of open access articles and addresses the question 'What can health science librarians do to ensure that the public are able to find, appraise and use health information?' This material provides research evidence, and examples of the types of initiatives librarians have undertaken to make information a health and care service in its own right. Two recurrent messages are that health science librarians need to form partnerships with healthcare providers and they have a role to play in improving health literacy skills. © 2013 The authors.

    The carcinoma at Merkel cells is a rare and aggressive skin cancer, principally of the aged adult. The surgery is the fundamental treatment. The interest of the adjuvant radiotherapy is discussed for the aged patient. In the limits of this retrospective analysis, the postoperative radiotherapy appeared to bring a similar benefit as for younger patients. (N.C.)

    Results of Rb/Sr-age determinations from six mica schists, sampled in the upper part of the Shackleton metamorphic complex (Herbert Mountains, Shackleton Range, Antarctica) are reported. A three point isochrone gives an age of 470 +- 36 mio. yrs., a two point isochrone an age of 1414 +- 185 mio yrs. The first age marks a thermo-magmatic activation of early paleozoic age, the second one is interpretated as the age of regional metamorphism from the upper parts of the Shackleton metamorphic complex. The results are discussed under consideration of former age determinations. (author)

    Conclusion: Findings of the present study showed that PSA levels are correlated with age. It was also revealed that the PSA age-specific reference range obtained in this study is different from other races and is specific to Iranian men. Therefore, age-specific reference ranges of PSA obtained in the present study can increase PSA test sensitivity and specificity by reducing unnecessary diagnostic procedures and early detection of prostate cancer in Iranian men.

  13. Differential range use between age classes of southern African Bearded Vultures Gypaetus barbatus.

    Full Text Available Bearded Vulture Gypaetus barbatus movements were investigated in southern Africa to determine whether an individual's age, sex or breeding status influenced its ranging behaviour and to provide the information required to guide conservation activities. Data from satellite transmitters fitted to 18 individuals of four age classes were used to determine range size and use. Because of the nature of the movements of marked individuals, these data could be used to determine the overall foraging range of the entire population, which was estimated to be 51 767 km(2. Although juvenile, immature and sub-adult birds used different parts of the overall range, their combined foraging range was 65% (33 636 km(2 of the overall range. Average adult home ranges (286 km(2 were only around 1% the size of the average foraging ranges of non-adults (10 540 -25 985 km(2, with those of breeding adults being even smaller (95 km(2. Home ranges of breeding adults did not vary in size between seasons but adults utilized their home range more intensively whilst breeding, moving greater distances during the incubation and chick hatching period. Range size and use increased as non-adults aged. Immatures and sub-adults had larger range sizes during winter, but range use of non-adults did not vary seasonally. Range size and use did not differ between the sexes in any of the age classes. Information on home range size and use enables specific areas within the species' range to be targeted for management planning, education and conservation action.

    The results and problems of radiotherapy were analyzed in 57 lung cancer patients more than 65 years of age (average age: 74.8 years). Of these, 45 (79%) were irradiated with a total dose exceeding 40 Gy. In these patients, the median survival was 13 months for Stages I and II, 6.5 months for Stage III, and 5 months for Stage IV. The results of combined radiotherapy and chemotherapy were better than those of radiotherapy alone. Also, slightly better results were obtained in patients treated with split-course than continuous-course irradiation. In aged lung cancer patients the prognosis was highly influenced by their respiratory function. Double cancers were present in 9 (16%) of the 57 patients. (author)

    The dramatic rise in the number of refugees entering Germany means that age estimation for juveniles and young adults whose age is unclear but relevant to legal and official procedures has become more important than ever. Until now, whether and to what extent the combination of methods recommended by the Study Group on Forensic Age Diagnostics has resulted in a reduction of the range of scatter of the summarized age diagnosis has been unclear. Hand skeletal age, third molar mineralization stage and ossification stage of the medial clavicular epiphyses were determined for 307 individuals aged between 10 and 29 at time of death on whom autopsies were performed at the Institutes of Legal Medicine in Berlin, Frankfurt am Main and Hamburg between 2001 and 2011. To measure the range of scatter, linear regression analysis was used to calculate the standard error of estimate for each of the above methods individually and in combination. It was found that combining the above methods led to a reduction in the range of scatter. Due to various limitations of the study, the statistical parameters determined cannot, however, be used for age estimation practice.

    Autologous disc cell implantation, growth factors and gene therapy appear to be promising therapies for disc regeneration. Unfortunately, the replicative lifespan and growth kinetics of human nucleus pulposus (NP) cells related to host age are unclear. We investigated the potential relations among age, replicative lifespan and growth rate of NP cells, and determined the age range that is suitable for cell-based biological therapies for degenerative disc diseases. We used NP tissues classified by decade into five age groups: 30s, 40s, 50s, 60s and 70s. The mean cumulative population doubling level (PDL) and population doubling rate (PDR) of NP cells were assessed by decade. We also investigated correlations between cumulative PDL and age, and between PDR and age. The mean cumulative PDL and PDR decreased significantly in patients in their 60s. The mean cumulative PDL and PDR in the younger groups (30s, 40s and 50s) were significantly higher than those in the older groups (60s and 70s). There also were significant negative correlations between cumulative PDL and age, and between PDR and age. We found that the replicative lifespan and growth rate of human NP cells decreased with age. The replicative potential of NP cells decreased significantly in patients 60 years old and older. Young individuals less than 60 years old may be suitable candidates for NP cell-based biological therapies for treating degenerative disc diseases.

    2000-11-01

    Visual search for compound patterns was examined in observers aged 6, 8, 10, and 22 years. The main question was whether age-related improvement in search rate (response time slope over number of items) was different for patterns defined by short- versus long-range spatial relations. Perceptual access to each type of relation was varied by using elements of same contrast (easy to access) or mixed contrast (hard to access). The results showed large improvements with age in search rate for long-range targets; search rate for short-range targets was fairly constant across age. This pattern held regardless of whether perceptual access to a target was easy or hard, supporting the hypothesis that different processes are involved in perceptual grouping at these two levels. The results also point to important links between ontogenic and microgenic change in perception (H. Werner, 1948, 1957).

    Although negative affect in general has been widely associated with suicide, the role of specific emotions and affect features in depression and suicidality is unclear. This study examined the potential of three major components of the affect structure as predictors of suicidal behavior. Twenty suicidal depressed (SD) inpatients were compared with 20 nonsuicidal depressed (NSD) inpatients and 20 healthy controls for alexithymia, emotional range (ER; i.e. variety of emotions experienced by the subjects) and affect intensity (AI; i.e. the intensity of their emotional responsiveness). Both the SD and the NSD patients had a narrower range of emotions, a stronger AI and a higher degree of alexithymia than did the healthy controls. No differences were found between the scores of the two inpatients groups. The three affect components examined (alexithymia, AI and ER) did not prove to represent sensitive predictors of suicidal behavior. Hopelessness and depression severity were found to be more reliable in the prediction of suicidal risk. We discuss the implications of this study, particularly the possibility of early detection and intervention in patients at risk.

  19. Exploring procedures for the rapid assessment of optically stimulated luminescence range-finder ages

    2009-01-01

    Optically stimulated luminescence (OSL) dating of sediments is a lengthy, labour-intensive, and time-consuming procedure. However, in some situations a rough approximation of the OSL age is all that is necessary e.g. for a pilot field campaign, to plan a sampling strategy, or to determine the resolution required for a dating campaign. Thus, it would be useful to establish an approximate OSL age without the lengthy and involved processes normally used. This paper explores how the standard procedures involved in OSL age determinations can be simplified to yield range-finder ages. Three areas are examined, namely, laboratory preparation, D e estimation, and dose-rate determination. The consequences of circumventing some of the preparation and measurement steps of conventional OSL dating are examined for a variety of sediments, by comparing the OSL range-finder ages to those obtained using full quartz OSL preparation and measurement procedures.

  20. Effects of age and health on the euthyroid reference ranges for serum free thyroxine and free triiodothyronine

    Midgley, J.E.M.

    1985-01-01

    Age-related trends in serum free thyroxine (FT 4 ) and free triiodothyronine (FT 3 ) concentrations were measured in 7248 euthyroid subjects (age-range 3 months to 106 years). 5700 were patients referred to hospitals for investigation of suspected thyroid dysfunction, but who were diagnosed euthyroid. 1548 were healthy blood donors (age-range 18-63 years) with no indication of thyroid dysfunction. FT 4 concentrations were little affected by the age, the sex or the state of health of the subjects in either group. Serum FT 3 concentrations were significantly affected by both age and health factors. The upper limit of the euthyroid reference range for young subjects up to 15 years was about 20% higher (10.4 pmol/l) than for adult subjects older than 25 years (8.8 pmol/l). The change in the upper limits typical of young subjects to that typical of adults occurred steadily over the decade 15-25 years. After this age, little further change occurred, especially in healthy subjects. Additionally, the lower limit of the euthyroid range for FT 3 was extended by the inclusion in the reference group of patients referred to hospitals. Compared with the lower limit of the FT 3 range for healthy subjects (5 pmol/l), the corresponding limit for referred subjects (young or adult) was 3.5-3.8 pmol/l. Broadening of the FT 3 reference range was probably brought about by a significant number of patients in the hospital-referred group with the 'low-T 3 syndrome' of mild non-thyroidal illness. Accordingly, FT 3 was inferior to FT 4 in the discrimination of hypothyroidism, as FT 4 was unaffected by this phenomenon. Effects of age and non-thyroidal illness on serum FT 3 concentrations require great care when selecting subjects for a laboratory euthyroid reference range typical of the routine workload. Constraints on the choice of subjects for FT 4 reference ranges are less stringent. (orig.) [de

    The Haller index is an accepted CT method for evaluating thoracic dimensions in patients with pectus excavatum. The purpose of this study is to establish age- and gender-related norms for the Haller index in childhood. We retrospectively reviewed 574 consecutive chest CT examinations (M=285, F=289) performed at our institution from August 2001 through March 2002. Seventeen patients with a history of chest-wall deformity, trauma, or syndrome were excluded, for a total sample size of 557 patients. The Haller index was calculated for each patient, using electronic calipers. The sample population was then separated by gender and placed into 2-year age groupings. Two-way analysis of variance and Tukey's multiple comparisons were performed to determine significance at a=0.05. The least-square mean Haller index values for each age group and gender were calculated with 95% confidence intervals. In both males and females, the 0- to 2-year age group showed a significantly smaller mean Haller index than older children. In addition, females had significantly greater Haller index values than males in the 0- to 6- and 12- to 18-year age groups. The Haller index, a quantitative measurement of chest-wall configuration, demonstrates significant age- and gender-related variability. This should be considered when evaluating the patient with suspected chest-wall deformity. (orig.)

    Age-related reference ranges are useful for assessing growth in children. The LMS method is a popular technique for constructing growth charts that model the age-changing distribution of the measurement in terms of the median, coefficient of variation and skewness. Here the methodology is extended to references that depend on body size as well as age, by exploiting the flexibility of the generalised additive models for location, scale and shape (GAMLSS) technique. GAMLSS offers general linear predictors for each moment parameter and a choice of error distributions, which can handle kurtosis as well as skewness. A key question with such references is the nature of the age-size adjustment, additive or multiplicative, which is explored by comparing the identity link and log link for the median predictor.There are several measurements whose reference ranges depend on both body size and age. As an example, models are developed here for the first four moments of the lung function variables forced expiratory volume in 1 s (FEV(1)), forced vital capacity (FVC) and FEV(1)/FVC in terms of height and age, in a data set of 3598 children and adults aged 4 to 80 years. The results show a strong multiplicative association between spirometry, height and age, with a large and nonlinear age effect across the age range. Variability also depends nonlinearly on age and to a lesser extent on height. FEV(1) and FVC are close to normally distributed, while FEV(1)/FVC is appreciably skew to the left. GAMLSS is a powerful technique for the construction of such references, which should be useful in clinical medicine. Copyright (c) 2008 John Wiley & Sons, Ltd.

    in the sparse clinical data. Model-predicted doses (based on age and body weight) to maintain a recommended 0.01 U/mL trough level of FVIII with administration on alternate days started at around 60 U/kg in the small children, decreasing to 10 U/kg or less in middle age. However, "true" dose requirements......, as estimated from individual PK parameter data, showed a much greater variation. CONCLUSION: Appropriate dosing of FVIII for prophylactic treatment cannot be calculated only from body weight and/or age. However, plausible starting doses for most patients would be 1,000 U every other day. FVIII levels should...... can be calculated according to patient characteristics, and (3) to present dosing recommendations for initiating prophylactic treatment. METHODS: A population PK model was developed using data from four PK studies on patients aged 7-74 years. The model was tested on sparse FVIII data from 42...

    The width of interhemispheric fissure, lateral ventricles and third ventricle were measured using cranial computed tomography (CT; linear method) in 45 elderly inpatients with chronic schizophrenia and in 28 age-matched control subjects. Twenty-three patients were men and 22 were women. In addition, Mini-Mental State Examination, Brief Psychiatric Rating Scale (BPRS) and a subclass of BPRS were undertaken in all patients. There is a significant enlargement of the maximum width of the interhemispheric fissure (in both male and female) and a significant enlargement of ventricular system (more severe in men than in women) in aged schizophrenics, as seen with CT, compared with normal controls. These findings are consistent with previous studies of non-aged schizophrenic patients. Based upon the relation between psychiatric symptoms and CT findings, the most striking is a significant negative correlation between the third ventricle enlargement and the positive and depressive symptoms in all patients. This result suggests that the advanced third ventricle enlargement may decrease these symptoms in aged schizophrenics. (author)

    Erosion by tsunami waves represents an important issue when determining the age of a tsunami deposit, because the age is usually estimated using dating of sediments above and below the deposit. Dating of material within the tsunami deposit, if suitable material is obtainable, can be used to further constrain its age. Eroded sediments are sometimes incorporated within the tsunami deposits as rip-up clasts, which might therefore be used as minimum age dating material. However, the single calibrated 14C age often shows a wide age range because of fluctuations in the calibration curve. Therefore, it remains uncertain whether rip-up clast measurements are useful to constrain the depositional age of tsunami deposits, or not. In this study, we carried out high-resolution 14C dating of tsunami deposits, including rip-up clasts of peat, in Rikuzentakata, northeastern Japan, where numerous rip-up clasts were observed within a tsunami deposit. Sediments above and below the tsunami deposit and a 5 cm large rip-up clast were dated sequentially. Comparison of these dating results with the calibration curve revealed that the clast was inverted. Its age was better constrained based on the stratigraphic order, and we infer that the clast corresponds to approximately 100 years of sedimentation. The oldest age of the clast was consistent with the age of the peat immediately below the tsunami deposit, suggesting that surface sediments probably formed the rip-up clast at the time of the tsunami. Thus, the dating of the rip-up clast was useful to further constrain the depositional age of the tsunami deposit, as we narrowed the tsunami deposit age range by approximately 100 years. Results show that ignoring tsunami-related erosion might lead to overestimation of the tsunami deposit age. For this reason, an appropriate dating site, which is less affected by minor tsunami-related erosion with regards to the paleo-topography, should be explored. We therefore propose a more effective

    Alteration of dynamic range of modulation to cognitive difficulty has been proposed as a salient predictor of cognitive aging. Here, we examine in 171 adults (aged 20-94 years) the effects of age on dynamic modulation of blood oxygenation-level dependent activation to difficulty in parametrically increasing working memory (WM) load (0-, 2-, 3-, and 4-back conditions). First, we examined parametric increases and decreases in activation to increasing WM load (positive modulation effect and negative modulation effect). Second, we examined the effect of age on modulation to difficulty (WM load) to identify regions that differed with age as difficulty increased (age-related positive and negative modulation effects). Weakened modulation to difficulty with age was found in both the positive modulation (middle frontal, superior/inferior parietal) and negative modulation effect (deactivated) regions (insula, cingulate, medial superior frontal, fusiform, and parahippocampal gyri, hippocampus, and lateral occipital cortex). Age-related alterations to positive modulation emerged later in the lifespan than negative modulation. Furthermore, these effects were significantly coupled in that greater upmodulation was associated with lesser downmodulation. Importantly, greater fronto-parietal upmodulation to difficulty and greater downmodulation of deactivated regions were associated with better task accuracy and upmodulation with better WM span measured outside the scanner. These findings suggest that greater dynamic range of modulation of activation to cognitive challenge is in service of current task performance, as well as generalizing to cognitive ability beyond the scanner task, lending support to its utility as a marker of successful cognitive aging.

    The purpose of this study was to assess the age of patients at the time of extraction of third molars. Our data included all routine and surgical extractions of third molars (n=8199 teeth) performed by general and specialist dentists of the public oral health services of the city of Helsinki over the period 2013-2014. Measurements included patient's age, gender, the identified third molar, the type of anaesthesia, the method of extraction, and the diagnosis at extraction. Patients' ages ranged from 10 to 99years. We found significant differences between younger and older age groups: third molar extractions occurred more often for women than for men below the age of 30years (Page of 40years, but the corresponding prevalences reversed after the age of 40years. Diagnoses at extraction differed between younger and older patients. We conclude that the treatment pattern of third molars at public health services varies greatly over a lifetime, and that a greater variety exists than had been reported previously from oral and maxillofacial units.

    In addition to measures already used in clinical practice, molecular measures have been proposed to assess health status, but these have not yet been introduced into clinical practice. We aimed to test the association of functional capacity measures used in current practice and molecular measures...... with age and health status. The cohort consisted of 178 middle-aged to old participants of the Leiden Longevity Study (range 42-82years). We tested associations between functional capacity measures (physical tests: grip strength, 4-meter walk, chair stand test; cognitive tests: Stroop test, digit symbol...... substitution test and 15-picture learning test) with age and with cardiovascular or metabolic disease as a measure of the health status. These associations with age and health status were also tested for molecular measures (C reactive protein (CRP), numbers of senescent p16INK4a positive cells in the epidermis...

    Reduced motor control is one of the most frequent features associated with aging and disease. Nonlinear and fractal analyses have proved to be useful in investigating human physiological alterations with age and disease. Similar findings have not been established for any of the model organisms typically studied by biologists, though. If the physiology of a simpler model organism displays the same characteristics, this fact would open a new research window on the control mechanisms that organisms use to regulate physiological processes during aging and stress. Here, we use a recently introduced animal-tracking technology to simultaneously follow tens of Caenorhabdits elegans for several hours and use tools from fractal physiology to quantitatively evaluate the effects of aging and temperature stress on nematode motility. Similar to human physiological signals, scaling analysis reveals long-range correlations in numerous motility variables, fractal properties in behavioral shifts, and fluctuation dynamics over a wide range of timescales. These properties change as a result of a superposition of age and stress-related adaptive mechanisms that regulate motility.

    K-Ar and zircon fission-track dating was carried out on some granitic rocks in the Hida Range, central Japan. The samples analyzed were collected on both sides of one of the major faults in the Hida Range: the Kurobe-Takase fracture zone. Ages obtained west of the fault are ∼60 Ma, while those obtained to the east of the fault are less than ∼5 Ma. These results indicate a remarkable age difference across the fault. The Okukurobe granite, located west of the fault, cooled rapidly from ∼600degC to ∼240degC between 60-55 Ma, and the Kanazawa granodiorite, located east of the fault, cooled rapidly from ∼600degC to ∼240degC between 5-1 Ma. The Okukurobe granite has remained cooler than ∼240degC since ∼55 Ma. Thus, it was found that the granitic rocks across the fault have experienced a remarkable different cooling history. (author)

    The aim of the study was to evaluate the cervical vertebral maturation and dental age, in group of patients with coelic disease (CD), in comparison with a control group of healthy subjects. At the Paediatric Dentistry Unit of PTV Hospital, "Tor Vergata" University of Rome, 120 female patients, age range 12.0-12.9 years were recruited. Among them, 60 subjects (Group 1) were affected by CD, while the control group (Group 2) consisted of 60 healthy subjects, sex and age-matched. The Group 1 was subdivided, according to the period of CD diagnosis, in Group A (early diagnosis) and Group B (late diagnosis). The skeletal age was determined by assessing the cervical vertebral maturation, while the dental age has been determined using the method codified by Demirjiyan. STATISTICS.: The analyses were performed using the SPSS software (version 16; SPSS Inc., Chicago IL, USA). In all the assessments a significant level of alpha = 0.05 was considered. There are no statistically significant differences between Group 1 and Group 2 as for chronological age (p=0.122). Instead, from the assessment of skeletal-dental age, there are statistically significant differences between Group 1 - Group 2 (pcervical vertebral maturity can be assessed with a low cost, non invasive, easy to perform exam carried out through the routine radiographic examinations such as orthopanoramic and lateral teleradiography.

    Calf mortality and morbidity commonly occurs within the first month of life postpartum. Standard health ranges are invaluable aids in diagnostic veterinary medicine to confirm normal or the degree and nature of abnormal parameters in (sub)clinically ill animals. Extensive research has indicated significant differences between the physiologies of neonate and adult cattle, particularly for blood parameters such as pH, base excess, anion gap, and bicarbonate (HCO 3 - ). The objective of this research was to determine the influence of age, sex, and breed type, in addition to environmental factors, on the normal blood gas profiles of neonatal calves, and thus develop a scientifically validated reference range accounting for any significant factors. The study was conducted on healthy neonatal calves (n = 288), and completed over a 2-yr period. Individual calf blood gas analysis was conducted for parameters of pH, base excess, Na + , K + , Ca 2+ , Cl - , glucose, total hemoglobin, HCO 3 - , pCO 2 , anion gap, strong ion difference, and hematocrit levels. Regression procedures examined the combined effect of year, farm, age, breed type, sex, and hours postfeeding on each variable. Significant effects were observed for age, sex, and breed type on several of the blood gas variables. Furthermore, year, farm, and hours postfeeding appeared to have less of an influence on neonatal bovine blood gas profiles. Consequently, specific ranges based on the neonate's age, sex, and breed type will allow for more detailed and accurate diagnosis of health and ill health in neonatal calves. The Authors.

    The microstructure of sleep, which translates the short-lived fluctuations of the arousal level, is a commonly neglected feature in polysomnographic studies. Specifically arranged microstructural EEG events may provide important information on the dynamic characteristics of the sleep process. CAP (cyclic alternating pattern) and non-CAP are complementary modalities in which arousal-related "phasic" EEG phenomena are organized in non-REM sleep, and they correspond to opposite conditions of unstable and stable sleep depth, respectively. Thus, arousal instability can be measured by the CAP rate, the percentage ratio of total CAP time to total non-REM sleep time. The CAP rate, an age-related physiological variable that increases in several pathological conditions, is highly sensitive to acoustic perturbation. In the present study, two groups of healthy subjects without complaints about sleep, belonging to different age ranges (six young adults, three males and three females, between 20 and 30 years, and six middle-aged individuals, three males and three females, between 40 and 55 years) slept, after adaptation to the sleep laboratory, in a random sequence for two non-consecutive nights either under silent baseline (27·3 dB(A) Lcq) or noise-disturbed (continuous 55 dB(A) white noise) conditions. Age-related and noise-related effects on traditional sleep parameters and on the CAP rate were statistically evaluated by a split-plot test. Compared to young adults, the middle-aged individuals showed a significant reduction of total sleep time, stage 2 and REM sleep and significantly higher values of nocturnal awakenings and the CAP rate. The noisy nights were characterized by similar alterations. The disruptive effects of acoustic perturbation were greater on the more fragile sleep architecture of the older group. The increased fragility of sleep associated with aging probably reflects the decreased capacity of the sleeping brain to maintain steady states of vigilance. Total

    Full Text Available Introduction: Someone attached by stroke can’t do their activity fluently because stroke can cause the weakness of motor and sensor function. This condition cause physical defect and give effect in social and economic too, because someone who suffered stroke usually still in productive age. The objective of this study was to examine the effect of arm range of motion in the muscle strength of post stroke patient. Method: Pre experimental pre–post test design was used in this study. Population of this study was post stroke patient in Wijayakusuma ward dr. Soedono Hospital and total samples were 11 respondents. Independent variable was arm range of motion exercise, dependent variable was strength of arm muscle. Data were collected by observation with manual muscle testing of Lovelt, Naniel and Worthinghom and then analyzed using wilcoxon signed rank test with signi fi cant level of α ≤ 0.05. Result: The result showed that 11 respondents had increased their strength of muscle (p = 0.04. Discussion: It can be concluded that the strength of muscle increased after get arm range of motion exercise. When range of motion had been done Ca+ will be activated by cell so that happen integrity of muscle protein. If Ca+ and troponin had been activated, actin and myosin would have been defensed, so that can moved the skeletal and followed by muscle contraction, expand, outgrow and had a tonus. This condition can showed the strength of muscle.

    Free range feeding pattern puts the chicken in a mixture of growth materials and enteric bacteria excreted by nature, while it is typically unique condition materials and enteric bacteria in commercial caged hens production. Thus, the gastrointestinal microflora in two feeding patterns could be various. However, it remains poorly understood how feeding patterns affect development and composition of layer hens' intestinal microflora. In this study, the effect of feeding patterns on the bacteria community in layer hens' gut was investigated using free range and caged feeding form. Samples of whole small intestines and cecal digesta were collected from young hens (8-weeks) and mature laying hens (30-weeks). Based on analysis using polymerase chain reaction-denaturing gradient gel electrophoresis and sequencing of bacterial 16S rDNA gene amplicons, the microflora of all intestinal contents were affected by both feeding patterns and age of hens. Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria, and Fusobacteria were the main components. Additionally, uncultured environmental samples were found too. There were large differences between young hens and adult laying hens, the latter had more Firmicutes and Bacteroidetes, and bacterial community is more abundant in 30-weeks laying hens of all six phyla than 8-weeks young hens of only two phyla. In addition, the differences were also observed between free range and caged hens. Free range hens had richer Actinobacteria, Bacteroidetes, and Proteobacteria. Most of strains found were detected more abundant in small intestines than in cecum. Also the selected Lactic acid bacteria from hens gut were applied in feed and they had beneficial effects on growth performance and jejunal villus growth of young broilers. This study suggested that feeding patterns have an importance effect on the microflora composition of hens, which may impact the host nutritional status and intestinal health.

    European Society of Cardiology heart failure guidelines include a new patient category with mid-range (40%-49%) left ventricular ejection fraction (HFmrEF). HFmrEF patient characteristics and prognosis are poorly defined. The aim of this study was to analyze the HFmrEF category in a cohort of hospitalized heart failure patients (REDINSCOR II Registry). A prospective observational study was conducted with 1420 patients classified according to ejection fraction as follows: HFrEF, < 40%; HFmrEF, 40%-49%; and HFpEF, ≥ 50%. Baseline patient characteristics were examined, and outcome measures were mortality and readmission for heart failure at 1-, 6-, and 12-month follow-up. Propensity score matching was used to compare the HFmrEF group with the other ejection fraction groups. Among the study participants, 583 (41%) had HFrEF, 227 (16%) HFmrEF, and 610 (43%) HFpEF. HFmrEF patients had a clinical profile similar to that of HFpEF patients in terms of age, blood pressure, and atrial fibrillation prevalence, but shared with HFrEF patients a higher proportion of male participants and ischemic etiology, and use of class I drugs targeting HFrEF. All other features were intermediate, and comorbidities were similar among the 3 groups. There were no significant differences in all-cause mortality, cause of death, or heart failure readmission. The similar outcomes were confirmed in the propensity score matched cohorts. The HFmrEF patient group has characteristics between the HFrEF and HFpEF groups, with more similarities to the HFpEF group. No between-group differences were observed in total mortality, cause of death, or heart failure readmission. Copyright © 2016 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

    Maple syrup urine disease (MSUD), an inborn error of amino acids catabolism is characterized by accumulation of branched chain amino acids (BCAAs) leucine, isoleucine, valine and their corresponding alpha-ketoacids. Impact on the cognitive development has been reported historically, with developmental delays of varying degree. Currently, earlier diagnosis and improved management allow a better neurodevelopment, without requirement of special education. However, specific impairments can be observed, and so far, results of detailed neurocognitive assessments are not available. The aim of this study was to analyse neurocognitive profiles of French MSUD patients. This was a multicentre retrospective study on MSUD patients who underwent neurocognitive evaluation at primary school age. Twenty-one patients with classical neonatal onset MSUD were included. The patients' mean age at the time of evaluation was 8.7 years. The mean intellectual quotient (IQ) score was in the normal range (95.1 ± 12.6). In a subset of eight patients, a consistent developmental pattern of higher verbal than performance IQ was observed (mean of the difference 25.7 ± 8.7, p < 0.0001). No correlation could be established between this pattern and long-term metabolic balance (BCAA blood levels), or severity of acute metabolic imbalances, or leucine blood levels at diagnosis and time to toxin removal procedure. These data show that some MSUD patients may exhibit an abnormal neurocognitive profile with higher verbal than performance abilities. This might suggest an executive dysfunction disorder that would need to be further investigated by specialized testing. This pattern is important to detect in MSUD, as appropriate neuropsychological treatment strategies should be proposed.

    The purpose of this study was to investigate the clinical efficacy and problems of radiotherapy for cancer patients aged 85 or older. Fifty-three patients (26 men, 27 women) who underwent radiotherapy were analyzed retrospectively. Median age was 87 years (range; 85-99). Treatment policy was classified into curative, semi-curative (treatment field or total dose were limited due to performance status) and palliative therapy. Head-and-neck, bladder and skin cancer were the most common primary disease. The treatment was deemed curative in 27%, semi-curative in 13%, and palliative in 49%. Total dose of semi-curative therapy was almost same compared with curative therapy. The rate of treatment completion and effectiveness were not significantly different in curative therapy and semi-curative therapy. We should consider to reduce the field size to gross target volume, but to treat with substantial dose to make radiotherapy safe and effective. We must be aware that elderly patients have basically low tolerability. (author)

    This quasi-experimental repeated measures study examined the relationship between centralization of symptoms and lumbar flexion and extension range of motion (ROM) in patients with low back pain. Rapid and lasting changes in lumbar ROM have been noted with centralization of symptoms. However, no study has objectively measured the changes in lumbar ROM occurring with centralization. Forty-two adult subjects (mean age, 45.68 years; SD=15.76 years) with low back pain and associated lower extremity symptoms were followed by McKenzie trained physical therapists. Subjects' lumbar ROM was measured at the beginning and end of each patient visit by using double inclinometers, and pain location was documented. Subjects were grouped as 1) centralized, 2) centralizing, or 3) noncentralized for comparisons of symptom and ROM changes. Data were analyzed by using multivariate analysis of variance and one-way analysis of variance. Significance was set at 0.05. A significant difference was found between initial and final mean extension ROM in the centralized and centralizing groups (p=0.003). No significant difference was found in the noncentralized group (p<0.05). Subjects (n=23) who demonstrated a change in pain location during the initial visit also showed a significant (p<0.001) change in extension ROM, whereas patients with no change in pain location (n=19) did not (p=0.848). Lumbar extension ROM increased as centralization occurred.

    Full Text Available The aim of the study was to evaluate and compare active and passive joint range of motion in children in relation to gender and age. This study involved 103 children (43 boys and 60 girls categorized into two groups: G1 (7 to 9 years old and G2 (10 to 12 years old. The flexitest protocol, active and passive, and the SAPO® were used to evaluate joint range of motion. A paired t test was applied to compare active and passive joint range of motion and an independent t test (p < .05 was used to compare active and passive range of motion between gender and age. Results showed that the passive joint ranges of motion of the lower limbs are higher than active motion (p < .001. Girls presented greater passive ankle flexion than boys did (p = .002. Children between 7 and 12 years of age presented similar standards of joint range of motion of low limb. Significant differences were found between passive and active angular range of motion in the hip, knee and ankle. There were no differences between boys and girls in the joint range of motion as well as among age groups.

    Full Text Available Objective: Temporomandibular disorders (TMD are the most common source of orofacial pain of a non-dental origin. The study was performed to investigate the therapeutic effect of the conventional occlusal splint therapy and the physical therapy. The hypothesis tested was that the simultaneous use of occlusal splint and physical therapy is an effective method for treatment of anterior disc displacement without reduction. Materials and Methods: Twelve patients (mean age =30.5 y with anterior disc displacement without reduction (according to RDC/TMD and confirmed by magnetic resonance imaging were randomly allocated into 2 groups: 6 received stabilization splint (SS and 6 received both physical therapy and stabilization splint (SS&PT. Treatment outcomes included pain-free opening (MCO, maximum assisted opening (MAO, path of mouth opening and pain as reported on visual analogue scale (VAS. Results: At baseline of treatment there were no significant differences among the groups for VAS scores, as well as for the range of mandibular movement. VAS scores improved significantly over time for the SS&PT group (F=28.964, p=0.0001, effect size =0.853 and SS group (F=8.794, p=0.001, effect size =0.638. The range of mouth opening improved significantly only in the SS&PT group (MCO: F=20.971, p=0.006; MAO: F=24.014, p=0.004 (Figure 2. Changes in path of mouth opening differ significantly between the groups (p=0.040. Only 1 patient in SS&PT group still presented deviations in mouth opening after completed therapy while in the SS group deviations were present in 5 patients after completed therapy. Conclusion: This limited study gave evidence that during the treatment period lasting for 6 months, the simultaneous use of stabilization splint and physical therapy was more efficient in reducing deviations and improving range of mouth opening than the stabilization splint used alone. Both treatment options were efficient in reducing pain in patients with anterior disc

    Full Text Available La prise en charge des patients diabétiques âgés est devenue aujourd’hui un véritable problème de santé publique du fait de l’augmentation du nombre des malades. Dans cette population, les complications du diabète sont plus graves et s’intriquent avec les manifestations plus spécifiquement gérontologiques. L’évaluation gériatrique standardisée est indispensable pour définir la situation de chaque malade selon son degré d’autonomie et de dénutrition, ses fonctions cognitives et son environnement social. Les objectifs thérapeutiques doivent être individualisés en fonction de la présentation clinique du patient. L’insulinothérapie est fréquemment incontournable et nécessite l’éducation du patient ou de son entourage. La prise en charge des patients diabétiques âgés doit éviter un trop grand laxisme chez une personne restée en bonne santé mais aussi un activisme déraisonnable chez les sujets fragiles en raison du risque hypoglycémique.

    Objectives We examined the association of night shift work history and age when night shift work was performed with cancer and cardiovascular disease risk factors among 54 724 women in the Nurses' Health Study (NHS) II. Methods We calculated age-adjusted and socioeconomic status-adjusted means and percentages for cancer and cardiovascular risk factors in 2009 across categories of night shift work history. We used multivariable-adjusted logistic regression to estimate odds ratios (ORs) and 95% CIs for key risk factors among 54 724 participants (72% ever shift workers). We further examined these associations by age (20–25, 26–35, 36– 45 and 46+ years) at which shift work was performed. Results Ever night shift workers had increased odds of obesity (body mass index ≥30 kg/m2; OR=1.37, 95% CI 1.31 to 1.43); higher caffeine intake (≥131 mg/day; OR=1.16, 95% CI 1.12 to 1.22) and total calorie intake (≥1715 kcal/day; OR=1.09, 95% CI 1.04 to 1.13); current smoking (OR=1.30, 95% CI 1.19 to 1.42); and shorter sleep durations (≤7 h of sleep/day; OR=1.19, 95% CI 1.15 to 1.24) compared to never night shift workers. These estimates varied depending on age at which night work was performed, with a suggestion that night shift work before age 25 was associated with fewer risk factors compared to night shift work at older ages. Conclusions Our results indicate that night shift work may contribute to an adverse chronic disease risk profile, and that risk factors may vary depending on the age at which night shift work was performed.

    According to the recent 2015 Nutrition Survey, the prevalence of being underweight (Body Mass Index, BMI pregnancy. For optimal weight gain during pregnancy, existing guidelines recommend different ranges of weight gain based on prepregnancy BMI. Owing to the absence of official GWG recommendations in Asian countries, including China and Taiwan, the US Institute of Medicine (IOM) guidelines are generally followed. However, Asian women are smaller and experience lower weight gains; therefore, excessive weight gain may lead to harmful events including macrosomia, preterm birth, preeclampsia, gestational diabetes, pregnancy-induced hypertension, and short- and long-term postpartum weight retention. Thus, an accurate GWG range should be determined for Asian women. We introduce one epidemiological study in which the optimal weight gain range was investigated by analyzing receiver-operating characteristic curves together with potential research ideas in this field with the aim of encouraging young researchers to solve this public health problem affecting mothers and children.

    We examined the association of night shift work history and age when night shift work was performed with cancer and cardiovascular disease risk factors among 54 724 women in the Nurses' Health Study (NHS) II. We calculated age-adjusted and socioeconomic status-adjusted means and percentages for cancer and cardiovascular risk factors in 2009 across categories of night shift work history. We used multivariable-adjusted logistic regression to estimate odds ratios (ORs) and 95% CIs for key risk factors among 54 724 participants (72% ever shift workers). We further examined these associations by age (20-25, 26-35, 36-45 and 46+ years) at which shift work was performed. Ever night shift workers had increased odds of obesity (body mass index ≥30 kg/m(2); OR=1.37, 95% CI 1.31 to 1.43); higher caffeine intake (≥131 mg/day; OR=1.16, 95% CI 1.12 to 1.22) and total calorie intake (≥1715 kcal/day; OR=1.09, 95% CI 1.04 to 1.13); current smoking (OR=1.30, 95% CI 1.19 to 1.42); and shorter sleep durations (≤7 h of sleep/day; OR=1.19, 95% CI 1.15 to 1.24) compared to never night shift workers. These estimates varied depending on age at which night work was performed, with a suggestion that night shift work before age 25 was associated with fewer risk factors compared to night shift work at older ages. Our results indicate that night shift work may contribute to an adverse chronic disease risk profile, and that risk factors may vary depending on the age at which night shift work was performed.

    Hospital admissions due to pneumonia range from 1.1 to 4 per 1,000 patients and this figure increases with age. Hospitalization causes a decline in functional status. Physical impairment impedes recovery and constitutes a higher risk of disability and mortality in elderly people. The objective of this study is to assess the impact of hospital stay in patients with pneumonia related with age. A total of 116 patients with pneumonia were included in this study, and divided into two age groups:psychological and emotional profile were evaluated. Pneumonia severity, nutritional status, independence and comorbidities were also assessed. Statistical analyses revealed significant differences between both age groups in pneumonia severity and comorbidities. Significant improvements between admission and discharge were found in lung function in both groups (pgroup.

    Strontium, oxygen and lead isotopic and rubidium-strontium geochronologic studies have been completed on Cretaceous and Jurassic (?) granitic rock samples from the northern Peninsular Ranges batholith in southern California. Many of these samples were collected systematically and studied chemically by A. K. Baird and colleagues (Baird and others, 1979). The distribution of these granitic rocks is shown in the Santa Ana, Perris, and San Jacinto Blocks, bounded by the Malibu Coast-Cucamonga, Banning, and San Andreas fault zones, and the Pacific Ocean on the map of the Peninsular Ranges batholith and surrounding area, southern California. The granitic rock names are by Baird and Miesch (1984) who used a modal mineral classification that Bateman and others (1963) used for granitic rocks in the Sierra Nevada batholith. In this classification, granitic rocks have at least 10% quartz. Boundaries between rock types are in terms of the ratio of alkali-feldspar to total feldspar: quartz diorite, 0-10%; granodiorite, 10-35%; quartz monzonite 35-65%; granite >65%. Gabbros have 0-10% quartz. Data for samples investigated are giv in three tables: samples, longitude, latitude, specific gravity and rock type (Table 1); rubidium and strontium data for granitic rocks of the northern Peninsular Ranges batholith, southern California (Table 2); U, Th, Pb concentrations, Pb and Sr initial isotopic compositions, and δ18O permil values for granitic rocks of the northern Peninsular Ranges batholith (table 3).

    Differences in pet dogs' and captive wolves' ability to follow human communicative intents have led to the proposition of several hypotheses regarding the possession and development of social cognitive skills in dogs. It is possible that the social cognitive abilities of pet dogs are induced by indirect conditioning through living with humans, and studying free-ranging dogs can provide deeper insights into differentiating between innate abilities and conditioning in dogs. Free-ranging dogs are mostly scavengers, indirectly depending on humans for their sustenance. Humans can act both as food providers and as threats to these dogs, and thus understanding human gestures can be a survival need for the free-ranging dogs. We tested the responsiveness of such dogs in urban areas toward simple human pointing cues using dynamic proximal points. Our experiment showed that pups readily follow proximal pointing and exhibit weaker avoidance to humans, but stop doing so at the later stages of development. While juveniles showed frequent and prolonged gaze alternations, only adults adjusted their behaviour based on the reliability of the human experimenter after being rewarded. Thus free-ranging dogs show a tendency to respond to human pointing gestures, with a certain level of behavioural plasticity that allows learning from ontogenic experience.

    Full Text Available To investigate nutritional status and body composition in different ages of maintaining hemodialysis (HD patients. 129 patients (male 62, female 67 with the mean age 56.33±14.14 years on HD were divided into four groups with age under 40, 40-69, 60-69 and over 70 years. Body composition was evaluated with Multi-frequency bioelectric impedance analysis (BIA and 83 healthy subjects, matched for age and sex, were as the control. In all patients, about 6.2% were underweight with body mass index (BMI less than 18.5 Kg/m2. The incidence of underweight were 0%, 6.2%, 4.8% and 11.1% in groups under 40, 40-59, 60-69 and over 70 years respectively. Serum Creatinine, ALB, pre-ALB and normalized protein catabolic rate (nPCR were significantly decreased in patients over 70 years. The young patients under 40 years also displayed lower nPCR and CHO value compared with that of group 40-59 years. Body cell mass, lean tissue mass, lean tissue index and relative lean tissue mass in HD patients were significantly lower than that in age and sex matched control group. Meanwhile, fat mass, fat tissue index and relative fat were increase 20% than the control. They were less different between HD patients and controls in age of 40-59 years, however, difference significantly increased in other three groups and changes were most obvious in patients over 70 years. In conclusion, our study showed that nutritional status was significantly associated with the age in HD patients. Patients under 40 years and over 70 years old displayed much severer protein wasting and more fat tissue storage.

    One of the primary sources of perceived stress is the social environment of an animal and the interactions with conspecifics. An essential component of the response to a stressor is the activation of the hypothalamic-pituitary-adrenocortical axis, which results amongst others in a temporal increase in circulating glucocorticoid (GC) levels. Giraffes occur in a highly flexible fission-fusion social system and group compositions can change on a daily basis, with bulls establishing an age-related dominance hierarchy and showing a roaming strategy in the search for fertile females. The aim of this study was to non-invasively monitor the influence of different group compositions (mixed sex groups vs. all-male groups) on GC concentrations in free ranging giraffe bulls of different age classes. We collected fecal samples from free-ranging giraffe bulls for 12months in a South African Private Game Reserve to examine age- and social context-related patterns of fecal GC metabolite (fGCM) concentrations. We found that fGCM levels in giraffe bulls are age-class dependent, as well asassociated with changes in the social environment. Independently of the social setting, bulls of the youngest age class exhibited the highest fGCM levels compared to bulls of the other two older age-classes, with differences most pronounced when the bulls are associated in all-male groups. In contrast, an almost reversed picture appears when looking at the fGCM levels of sexually active individuals in mixed sex groups, where highest levels were found for the bulls in the oldest age-class, and the lowest for the bulls in the youngest age-class. The study stresses the importance to taking factors such asage-related status and social settings into account, when interpreting fGCM levels in free ranging giraffes. Copyright © 2017 Elsevier Inc.

As we had further hypothesized, procrastination was consistently associated with higher stress, more depression, anxiety, fatigue and reduced satisfaction across life domains, especially regarding work and income. Associations were also found with lack of a partnership and unemployment. Findings are discussed with regard to potential developmental and cohort effects. While procrastination appears to be a pervasive indicator for maladjustment, longitudinal analyses in high-risk samples (e.g. late adolescence, unemployment are needed to identify means and mechanisms of procrastinating.

    One hundred and fifty-four patients with esophageal carcinoma were treated with either irradiation alone or irradiation combined with surgery at the University of Occupational and Environmental Health Hospital between January 1980 and February 1992. The number of patients 75 years old and older was 25. In patients 74 years old and younger, the overall five-year survival rate by Kaplan-Meier method was 24.5%. The survival rate was best in the patients who were treated by a combination of irradiation and surgery. In patients 75 years old and older, the one-year survival rate was 59%, and the three-year rate was 20%. Aged patients had a tendency to be worse in performance status, and there was no correlation between treatment modality and survival time. We conclude that radiotherapy is useful for treating esophageal cancer in aged patients particularly when maintenance of the quality of life is considered. (author)

  1. Clinical decision making in cancer care: a review of current and future roles of patient age.

    Patient age is among the most controversial patient characteristics in clinical decision making. In personalized cancer medicine it is important to understand how individual characteristics do affect practice and how to appropriately incorporate such factors into decision making. Some argue that using age in decision making is unethical, and how patient age should guide cancer care is unsettled. This article provides an overview of the use of age in clinical decision making and discusses how age can be relevant in the context of personalized medicine. We conducted a scoping review, searching Pubmed for English references published between 1985 and May 2017. References concerning cancer, with patients above the age of 18 and that discussed age in relation to diagnostic or treatment decisions were included. References that were non-medical or concerning patients below the age of 18, and references that were case reports, ongoing studies or opinion pieces were excluded. Additional references were collected through snowballing and from selected reports, guidelines and articles. Three hundred and forty-seven relevant references were identified. Patient age can have many and diverse roles in clinical decision making: Contextual roles linked to access (age influences how fast patients are referred to specialized care) and incidence (association between increasing age and increasing incidence rates for cancer); patient-relevant roles linked to physiology (age-related changes in drug metabolism) and comorbidity (association between increasing age and increasing number of comorbidities); and roles related to interventions, such as treatment (older patients receive substandard care) and outcome (survival varies by age). Patient age is integrated into cancer care decision making in a range of ways that makes it difficult to claim age-neutrality. Acknowledging this and being more transparent about the use of age in decision making are likely to promote better clinical decisions

  2. Withdrawal of corticosteroids in inflammatory bowel disease patients after dependency periods ranging from 2 to 45 years: a proposed method.

    Murphy, S J

    2012-02-01

    BACKGROUND: Even in the biologic era, corticosteroid dependency in IBD patients is common and causes a lot of morbidity, but methods of withdrawal are not well described. AIM: To assess the effectiveness of a corticosteroid withdrawal method. METHODS: Twelve patients (10 men, 2 women; 6 ulcerative colitis, 6 Crohn\\'s disease), median age 53.5 years (range 29-75) were included. IBD patients with quiescent disease refractory to conventional weaning were transitioned to oral dexamethasone, educated about symptoms of the corticosteroid withdrawal syndrome (CWS) and weaned under the supervision of an endocrinologist. When patients failed to wean despite a slow weaning pace and their IBD remaining quiescent, low dose synthetic ACTH stimulation testing was performed to assess for adrenal insufficiency. Multivariate analysis was performed to assess predictors of a slow wean. RESULTS: Median durations for disease and corticosteroid dependency were 21 (range 3-45) and 14 (range 2-45) years respectively. Ten patients (83%) were successfully weaned after a median follow-up from final wean of 38 months (range 5-73). Disease flares occurred in two patients, CWS in five and ACTH testing was performed in 10. Multivariate analysis showed that longer duration of corticosteroid use appeared to be associated with a slower wean (P = 0.056). CONCLUSIONS: Corticosteroid withdrawal using this protocol had a high success rate and durable effect and was effective in patients with long-standing (up to 45 years) dependency. As symptoms of CWS mimic symptoms of IBD disease flares, gastroenterologists may have difficulty distinguishing them, which may be a contributory factor to the frequency of corticosteroid dependency in IBD patients.

    The oblique arc-continent collision between the Luzon arc and the southeastern margin of the Eurasian continent caused the uplift of Taiwan. The Coastal Range in eastern Taiwan is the northern section of the Luzon arc in the collision zone and thus records important information about the arc-continent collision. In this paper, we determine and analyze the U-Pb ages of magmatic zircons from the volcanic arc and clastic zircons from the fore-arc basin in the Coastal Range. For the volcanic arc in the Coastal Range, the eruption ages range from 16.8-5 Ma. Given that the initial subduction of the South China Sea oceanic crust (17 Ma) occurred before the Luzon arc formed, we conclude that the volcanic activity of the Coastal Range began at 16.8 ± 1.3 Ma; it was most active from 14 to 8 Ma and continued until approximately 5 Ma. The U-Pb chronology also indicates that the initial stage of arc-continent collision of the Coastal Range started at approximately 5 Ma, when the northern section of the Luzon arc moved away from the magmatic chamber because of the kinematics of the Philippine Sea Plate.

    To implement the DMAIC (Define-Measure-Analyze-Improve-Control) can be used for customizing the patient-specific QA by designing site-specific range tolerances. The DMAIC framework (process flow diagram, cause and effect, Pareto chart, control chart, and capability analysis) were utilized to determine the steps that need focus for improving the patient-specific QA. The patient-specific range QA plans were selected according to seven treatment site groups, a total of 1437 cases. The process capability index, C pm was used to guide the tolerance design of patient site-specific range. For prostate field, our results suggested that the patient range measurements were capable at the current tolerance level of ±1 mm in clinical proton plans. For other site-specific ranges, we analyzed that the tolerance tends to be overdesigned to insufficient process capability calculated by the patient-specific QA data. The customized tolerances were calculated for treatment sites. Control charts were constructed to simulate the patient QA time before and after the new tolerances were implemented. It is found that the total simulation QA time was decreased on average of approximately 20% after establishing new site-specific range tolerances. We simulated the financial impact of this project. The QA failure for whole process in proton therapy would lead up to approximately 30% increase in total cost. DMAIC framework can be used to provide an effective QA by setting customized tolerances. When tolerance design is customized, the quality is reasonably balanced with time and cost demands. © 2017 American Association of Physicists in Medicine.

    Full Text Available Summary: Background: Given the global increase in aging populations and cancer incidence, understanding the influence of age on postoperative outcome after cancer surgery is imperative. This study aimed to evaluate the impact of age on survival outcome in solid cancer patients receiving curative surgery. Methods: A total of 37,288 patients receiving curative surgeries for solid cancers between 2007 and 2012 at four affiliated Chang Gung Memorial Hospital were included in the study. All patients were categorized into age groups by decades for survival analysis. Results: The percentages of patient populations aged <40 years, 40–49 years, 50–59 years, 60–69 years, 70–79 years, and ≥80 years were 9.7%, 17.7%, 27.8%, 22.1%, 16.9%, and 5.7%, respectively. The median follow-up period was 38.9 months (range, 22.8–60.4 months and the overall, cancer-specific, and noncancer-specific mortality rates were 26.0%, 17.6%, and 8.5%, respectively. The overall mortality rate of patients in different age groups were 18.5%, 21.1%, 22.0%, 25.3%, 35.3%, and 49.0%, respectively. Compared to patients aged <40 years, more significant decrease in long-term survival were observed in aging patients. Multivariate analysis showed higher postoperative short-term mortality rates in patients older than 70 years, and the adjusted odds ratio of mortality risk ranged from 1.47 to 1.74 and 2.26 to 3.03 in patients aged 70–79 years and ≥80 years, respectively, compared to those aged <40 years. Conclusion: Aging was a negative prognostic factor of survival outcome in solid cancer patients receiving curative surgery. After adjustment of other clinicopathologic factors, the influence of age on survival outcome was less apparent in the elderly. Keywords: Age, Solid cancer, Surgical resection, Prognosis

    Purpose: Proton radiotherapy allows radiation treatment delivery with high dose gradients. The nature of such dose distributions increases the influence of patient positioning uncertainties on their fidelity when compared to photon radiotherapy. The present work quantitatively analyzes the influence of setup uncertainties on proton range and dose distributions. Methods: Thirty-eight clinical passive scattering treatment fields for small lesions in the head were studied. Dose distributions for shifted and rotated patient positions were Monte Carlo-simulated. Proton range uncertainties at the 50%- and 90%-dose falloff position were calculated considering 18 arbitrary combinations of maximal patient position shifts and rotations for two patient positioning methods. Normal tissue complication probabilities (NTCPs), equivalent uniform doses (EUDs), and tumor control probabilities (TCPs) were studied for organs at risk (OARs) and target volumes of eight patients. Results: The authors identified a median 1σ proton range uncertainty at the 50%-dose falloff of 2.8 mm for anatomy-based patient positioning and 1.6 mm for fiducial-based patient positioning as well as 7.2 and 5.8 mm for the 90%-dose falloff position, respectively. These range uncertainties were correlated to heterogeneity indices (HIs) calculated for each treatment field (38% < R{sup 2} < 50%). A NTCP increase of more than 10% (absolute) was observed for less than 2.9% (anatomy-based positioning) and 1.2% (fiducial-based positioning) of the studied OARs and patient shifts. For target volumes TCP decreases by more than 10% (absolute) occurred in less than 2.2% of the considered treatment scenarios for anatomy-based patient positioning and were nonexistent for fiducial-based patient positioning. EUD changes for target volumes were up to 35% (anatomy-based positioning) and 16% (fiducial-based positioning). Conclusions: The influence of patient positioning uncertainties on proton range in therapy of small lesions

    The aim of this study was to estimate the age of glacier ice in the No. 31 Glacier in the Suntar-Khayata Range of eastern Siberia by performing dating of insects thought to be long-legged fly species (Dolichopodidae) as well as plants (species unknown) fragments preserved in the ice. Ice samples containing organisms were collected at depths of 0.4–1.1 m at five points from the middle to lowest parts of the glacier in 2013. The age of an insect collected at the lowest point on the glacier was estimated as 2038 ± 32 yr B.P. Insects collected at higher points had a modern or near-modern radiocarbon age. The age of plant fragments collected at the uppermost and middle points was 1531 ± 44 and 1288 ± 26 yr B.P., respectively, and that of a mixture of plant and insect fragments collected at the lowest point was 9772 ± 42 yr B.P. When comparing specimens collected at the same point, the plant fragments were found to be older than the insects. In 2012–2014 observations, some living insects were found on the glacier, and thus the age of the insects appears to correspond to the age of the ice. On the other hand, the plant fragments might have already aged since detachment from the source plants. This study found an approximately 2000-year gap in the age of the ice between the lowest and higher points. Annual mass balance observations from 2012 to 2014 showed that in recent years, the glacier sometimes had no accumulation area. Therefore, the wide gap in the age of ice may be due to a difference in past melting processes between the lowest and higher points on the glacier.

    To date, there is no unified approach to evaluating and treating patients with suspected prostate cancer taking into account their age and comorbidities. That was the rationale for conducting this study. To assess the clinical course of prostate cancer in men of all ages with comorbidities. The study included 408 patients aged 50 to 92 years (mean age 74.3 years) with histologically verified prostate cancer. 30 (7.4%) patients had stage T1 disease, 273 (66.9%) - T2, 91 (22.3%) - T3 and 14 (3.4%) - T4. The maximum follow-up was 22 years, the minimum one - 6 months (on average 15.4 years). During the follow-up 159 patients died (39%), 51 of them (32%) of prostate cancer, 108 (68%) - from other diseases. Among the latter the causes of death were cancer (20.4%), cardiovascular and bronchopulmonary diseases (79.6%). Cancer-specific survival rate was 41.4 +/-12,4%, the survival rate for other diseases 23.4 +/-10,6% (pcancer, especially of old age, including the option for active surveillance of patients with clinically insignificant prostate cancer.

    When managing patients with acute respiratory distress syndrome (ARDS), respiratory system compliance is usually considered first and changes in resistance, although recognized, are neglected. Resistance can change considerably between minimum and maximum lung volume, but is generally assumed to be constant in the tidal volume range (V(T)). We measured resistance during tidal ventilation in 16 patients with ARDS or acute lung injury by the slice method and multiple linear regression analysis. Resistance was constant within V(T) in only six of 16 patients. In the remaining patients, resistance decreased, increased or showed complex changes. We conclude that resistance within V(T) varies considerably from patient to patient and that constant resistance within V(T) is not always likely.

    Patient navigation is increasingly being directed at adolescent and young adult (AYA) patients. This study provides a novel description of differences in AYA cancer patients' preferences for navigation services by developmental age at diagnosis. Eligible patients were diagnosed with cancer between ages 15 and 39 and had completed at least 1 month of treatment. Between October 2015 and January 2016, patients completed semi-structured interviews about navigation preferences. Summary statistics of demographic and cancer characteristics were generated. Differences in patient navigation preferences were examined through qualitative analyses by developmental age at diagnosis. AYAs were interviewed (adolescents 15-18 years N = 8; emerging adults 19-25 years N = 8; young adults 26-39 years N = 23). On average, participants were 4.5 years from diagnosis. All age groups were interested in face-to-face connection with a navigator and using multiple communication platforms (phone, text, email) to follow-up. Three of the most frequently cited needs were insurance, finances, and information. AYAs differed in support, healthcare, and resource preferences by developmental age; only adolescents preferred educational support. While all groups preferred financial and family support, the specific type of assistance (medical versus living expenses, partner/spouse, child, or parental assistance) varied by age group. AYAs with cancer have different preferences for patient navigation by developmental age at diagnosis. AYAs are not a one-size-fits-all population, and navigation programs can better assist AYAs when services are targeted to appropriate developmental ages. Future research should examine fertility and navigation preferences by time since diagnosis. While some navigation needs to span the AYA age range, other needs are specific to developmental age.

  13. Age and type of aphasia in patients with stroke.

    The age and gender of a series of patients with different types of aphasia were analysed. Regardless of gender, patients with Broca and conduction aphasias were significantly younger than those with Wernicke and global aphasias. Considering the established cerebral localisation of each of those aphasia types, it appears that, with age, stroke in the territory of the middle cerebral artery will tend to either shift posteriorly (producing Wernicke aphasia) or occupy most of the middle cerebral artery territory (producing global aphasia). But in the absence of concurrent verification of the locus of lesion in each of the cases in our sample, a possible alternative hypothesis must be entertained: that there might be age-related changes in the neurophysiological mechanism subserving language, such that some types of aphasia would tend to be more prevalent with age, regardless of lesion location.

    In a retrospective study the outcome of transurethral prostatectomy (TURP) for benign prostatic hyperplasia (BPH) in patients more than 80 years old was compared to a control group of patients with a mean age ten years younger. The elderly had significantly more tissue resected and presented...... with a higher rate of preoperative urinary tract infection. More urological complications were seen among the elderly but these were generally short lived and had no influence on the morbidity, mortality and symptomatic outcome. The perioperative mortality was 3.2% among elderly and 0% in the younger age group....... A cardiorespiratory risk score could not predict patients at risk. In conclusion the age per se had no major influence on the outcome of TURP....

    Thermal ageing of Alloy 690 triggers an intergranular (IG) carbide precipitation and is known to promote an ordering reaction causing lattice contraction. It may affect the long-term primary water stress corrosion cracking (PWSCC) resistance of pressurized water reactor (PWR) components. Four conditions of Alloy 690 (solution annealed, cold-rolled and/or heat-treated) were aged between 350 and 550 °C for 10 000 h and characterized. Although no direct observation of ordering was made, variations in hardness and lattice parameter were attributed to the formation of short-range ordering (SRO) in all conditions with a peak level at 420 °C, consistent with the literature. Prior heat treatment induced ordering before thermal ageing. At higher temperatures, stress relaxation, recrystallization and α-Cr precipitation were observed in the cold-worked samples, while a disordering reaction was inferred in all samples based on a decrease in hardness. IG precipitation of M{sub 23}C{sub 6} carbides increased with increasing ageing temperature in all conditions, as well as diffusion-induced grain boundary migration (DIGM). - Highlights: • SRO was suggested in Alloy 690 with 9.18 wt% Fe after thermal ageing at 350, 420 and 475 °C. • Prior thermal treatment promoted SRO before ageing. • Cold work led to recrystallization and precipitation of α-Cr upon ageing at 550 °C. • Thermal ageing promoted IG precipitation of Cr-rich M{sub 23}C{sub 6} carbides and DIGM.

    Many patients with heart failure need anticoagulants, including warfarin. Good control is particularly challenging in heart failure patients, with range, thereby increasing the risk of complications. This study aimed to evaluate the effect of a patient-specific tailored intervention on anticoagulation control in patients with heart failure. Patients with heart failure taking warfarin therapy (n = 145) were randomized to either standard care or a 1-time intervention assessing potential risk factors for lability of INR, in which they received patient-specific instructions. Time in therapeutic range (TTR) using Rosendaal's linear model was assessed 3 months before and after the intervention. The patient-tailored intervention significantly increased anticoagulation control. The median TTR levels before intervention were suboptimal in the interventional and control groups (53% vs 45%, P = .14). After intervention the median TTR increased significantly in the interventional group compared with the control group (80% [interquartile range, 62%-93%] vs 44% [29%-61%], P <.0001). The intervention resulted in a significant improvement in the interventional group before versus after intervention (53% vs 80%, P <.0001) but not in the control group (45% vs 44%, P = .95). The percentage of patients with a TTR ≥60%, considered therapeutic, was substantially higher in the interventional group: 79% versus 25% (P <.0001). The INR variability (standard deviation of each patient's INR measurements) decreased significantly in the interventional group, from 0.53 to 0.32 (P <.0001) after intervention but not in the control group. Patient-specific tailored intervention significantly improves anticoagulation therapy in patients with heart failure. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate the impact of asthma on patients in Brazil, by age group (12-17 years, 18-40 years, and ≥ 41 years). From a survey conducted in Latin America in 2011, we obtained data on 400 patients diagnosed with asthma and residing in one of four Brazilian state capitals (São Paulo, Rio de Janeiro, Curitiba, and Salvador). The data had been collected using a standardized questionnaire in face-to-face interviews. For the patients who were minors, the parents/guardians had completed the questionnaire. The questions addressed asthma control, number of hospitalizations, number of emergency room visits, and school/work absenteeism, as well as the impact of asthma on the quality of life, sleep, and leisure. We stratified the data by the selected age groups. The proportions of patients who responded in the affirmative to the following questions were significantly higher in the 12- to 17-year age group than in the other two groups: "Have you had at least one episode of severe asthma that prevented you from playing/exercising in the last 12 months?" (p = 0.012); "Have you been absent from school/work in the last 12 months?" (p age group reported that normal physical exertion was very limiting (p = 0.010 vs. the other groups), whereas 14% of the patients in the ≥ 41-year age group described social activities as very limiting (p = 0.011 vs. the other groups). In this sample, asthma had a greater impact on the patients between 12 and 17 years of age, which might be attributable to poor treatment compliance.

    Weathered felsite is associated with the late Campanian–Maastrichtian Pigeon Point Formation near Pescadero, California. Poorly exposed, its age and correlation are uncertain. Is it part of the Pigeon Point section west of the San Gregorio–Hosgri fault? Does it rest on Nacimiento block basement? Is it dextrally offset from the Oligocene Cambria Felsite, ∼185 km to the southeast? Why is a calc-alkaline hypabyssal igneous rock intrusive into the outboard accretionary prism? To address these questions, we analyzed 43 oscillatory-zoned zircon crystals from three incipiently recrystallized pumpellyite ± prehnite ± laumontite-bearing Pescadero felsite samples by sensitive high-resolution ion microprobe–reverse geometry (SHRIMP-RG) and laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) techniques. Thirty-three zircons gave late Mesozoic U-Pb ages, with single-grain values ranging from 81 to 167 Ma; ten have pre-Mesozoic, chiefly Proterozoic ages. A group of the four youngest Pescadero zircons yielded an apparent maximum igneous age of ca. 86–90 Ma. Reflecting broad age scatter and presence of partly digested sandstone inclusions, we interpret the rest of the zircons (perhaps all) as xenocrysts. Twenty-three zircons were separated and analyzed from two samples of the similar Cambria Felsite, yielding a unimodal 27 Ma U-Pb age. Clearly, the origin of the Upper Oligocene Cambria Felsite is different from that of the Upper Cretaceous Pescadero felsite; these rocks are not correlated, and do not constrain displacement along the San Gregorio–Hosgri fault. Peak ages differ slightly, but relative probability curves for Mesozoic and pre-Mesozoic Pescadero zircons compare well, for example, with abundant U-Pb age data for detrital zircons from Franciscan metaclastic strata ∼100 km to the east in the Diablo Range–San Francisco Bay area, San Joaquin Great Valley Group turbidites, Upper Cretaceous Nacimiento block Franciscan strata, and Upper

    Older cancer patients are a highly heterogeneous population in terms of global health and physiological reserves, and it is often difficult to determine the best treatment. Moreover, clinical tools currently used to assess global health require dedicated time and lack a standardized end score. Circulating markers of biological age and/or fitness could complement or partially substitute the existing screening tools. In this study we explored the relationship of potential ageing/frailty biomarkers with age and clinical frailty. On a population of 82 young and 162 older non-metastatic breast cancer patients, we measured mean leukocyte telomere length and plasma levels of interleukin-6 (IL-6), regulated upon activation, normal T cell expressed and secreted (RANTES), monocyte chemotactic protein 1 (MCP-1), insulin-like growth factor 1 (IGF-1). We also developed a new tool to summarize clinical frailty, designated Leuven Oncogeriatric Frailty Score (LOFS), by integrating GA results in a single, semi-continuous score. LOFS' median score was 8, on a scale from 0=frail to 10=fit. IL-6 levels were associated with chronological age in both groups and with clinical frailty in older breast cancer patients, whereas telomere length, IGF-1 and MCP-1 only correlated with age. Plasma IL-6 should be further explored as frailty biomarker in cancer patients.

    Time in therapeutic range (TTR) of international normalized ratio (INR) of 2.0 to 3.0 is important for the safety and effectiveness of warfarin anticoagulation. There are few data on TTR among patients with atrial fibrillation (AF) in community-based clinical practice. Using the US Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF), we examined TTR (using a modified Rosendaal method) among 5,210 patients with AF on warfarin and treated at 155 sites. Patients were grouped into quartiles based on TTR data. Multivariable logistic regression modeling with generalized estimating equations was used to determine patient and provider factors associated with the lowest (worst) TTR. Overall, 59% of the measured INR values were between 2.0 and 3.0, with an overall mean and median TTR of 65% ± 20% and 68% (interquartile range [IQR] 53%-79%). The median times below and above the therapeutic range were 17% (IQR 8%-29%) and 10% (IQR 3%-19%), respectively. Patients with renal dysfunction, advanced heart failure, frailty, prior valve surgery, and higher risk for bleeding (ATRIA score) or stroke (CHA2DS2-VASc score) had significantly lower TTR (P range.

    The primary coolant pump casings for Sizewell 'B' are made from castings of ASME SA351 CF3 steel which, although predominantly austenitic, is required to contain a small proportion of ferrite. Previous studies have shown that such steels are susceptible to hardening of the ferrite, and associated losses in toughness, as a result of thermal ageing for long times at the service temperature (∼ 300 0 C). For this reason, toughness tests are to be carried out on representative castings made by the Sizewell 'B' pump casing manufacturer. The purpose of these tests is to demonstrate adequate end-of-life fracture resistance, using material which has been given an accelerated ageing treatment. The identification and validation of a suitable ageing treatment is the subject of this Report. Ageing kinetics have been measured for ageing temperatures in the range 300 to 400 0 C, from the results of Charpy impact tests on material from the castings procured for the main fracture programme. Castings with ferrite levels of 15, 25 and 35% have been studied. The losses in impact toughness have been related to the kinetics of ferrite strengthening using microhardness measurements, and to microstructural changes using Field Ion Atom Probe analysis.

    Handball activity involves cardiac changes and demands a mixture of both eccentric and concentric remodeling within the heart. This study seeks to explore heart performance and cardiac remodeling likely to define cardiac parameters which influence specific performance in male handball players across different age ranges. Forty three players, with a regular training and competitive background in handball separated into three groups aged on average 11.78 ± 0.41 for youth players aka "schools", "elite juniors" 15.99 ± 0.81 and "elite adults" 24.46 ± 2.63 years, underwent echocardiography and ECG examinations. Incremental ergocycle and specific field (SFT) tests have also been conducted. With age and regular training and competition, myocardial remodeling in different age ranges exhibit significant differences in dilatation's parameters between "schools" and "juniors" players, such as the end-diastolic diameter (LVEDD) and the end-systolic diameter of the left ventricle (LVESD), the root of aorta (Ao) and left atrial (LA), while significant increase is observed between "juniors" and "adults" players in the interventricular septum (IVS), the posterior wall thicknesses (PWT) and LV mass index. ECG changes are also noted but NS differences were observed in studied parameters. For incremental maximal test, players demonstrate a significant increase in duration and total work between "schools" and "juniors" and, in total work only, between "juniors" and "seniors". The SFT shows improvement in performance which ranged between 26.17 ± 1.83 sec to 31.23 ± 2.34 sec respectively from "seniors" to "schools". The cross-sectional approach used to compare groups with prior hypothesis that there would be differences in exercise performance and cardiac parameters depending on duration of prior handball practice, leads to point out the early cardiac remodeling within the heart as adaptive change. Prevalence of cardiac chamber dilation with less hypertrophy remodeling was found

    Although numerous studies have assessed cognitive dysfunction in patients with schizophrenia, very few have focused on the diagnosis of dementia. Our objectives were to accurately diagnose dementia in a cohort of middle-aged patients with schizophrenia and to assess the type of dementia. 96 patients with schizophrenia (46 inpatients and 50 outpatients), aged 50 to 70 years, underwent a psychiatric, neurological, and neuropsychological evaluation at baseline and after a 20-month follow-up. We established a 3-step procedure: 1) diagnose dementia according to the DSM-IV criteria, using the Mattis Dementia Rating and Activities of Daily Living scales; 2) characterize dementia using brain imaging, perfusion by 99mTc-ECD-SPECT and laboratory tests including Alzheimer's disease cerebrospinal fluid biomarkers; and 3) search for genetic determinants. Fourteen patients fulfilled the diagnostic criteria of dementia. Four were diagnosed with possible or probable behavioral-variant frontotemporal dementia (bvFTD), two with probable Alzheimer's disease, two with probable vascular dementia (including one due to CADASIL), one with CNS inflammatory disease, and six could not be fully characterized. The diagnosis of dementia in middle-aged patients with schizophrenia is challenging but possible, using a multistep procedure. The most frequent condition, bvFTD, could reflect the presence of an evolutive neurodegenerative process in some patients.

The mean surgical time was 109 minutes. Prone position was needed in two cases, and no second surgeries were needed. The most common cause of systemic disease was hypertension, which was found in six cases. Transient hypertension was found in two cases during surgery, and these patients were treated using intravenous calcium blocker injections.Conclusion: Patients over 90 years of age who underwent vitrectomy procedures did not have serious problems, except transient hypertension during surgery. The BCVA significantly improved. These results indicated that vitrectomies could be performed successfully in patients over 90 years of age.

    Full Text Available Abstract Background Oxidative stress plays an important role in the course and eventual outcome in a majority of patients admitted to the intensive care unit (ICU. Markers to estimate oxidative stress are not readily available in a clinical setting. AGEs accumulation has been merely described in chronic conditions, but can also occur acutely due to oxidative stress. Since AGEs have emerged to be stable end products, these can be a marker of oxidative stress. Skin autofluorescence (AF is a validated marker of tissue content of AGEs. We hypothesized that AGEs accumulate acutely in ICU patients. Methods We performed an observational prospective study in a medical surgical ICU in a university affiliated teaching hospital. All consecutively admitted ICU patients in a 2 month period were included. Skin AF was measured using an AGE reader in 35 consecutive ICU patients > 18 yrs. As a comparison, historical data of a control group (n = 231 were used. These were also used to calculate age-adjusted AF-levels (AFadj. Values are expressed as median and interquartile range [P25-P75]. Differences between groups were tested by non parametric tests. P Results AFadj values were higher in ICU patients (0.33 [0.00 - 0.68] than in controls (-0.07 [-0.29 - 0.24]; P adj were observed between acute or planned admissions, or presence of sepsis, nor was skin AFadj related to severity of disease as estimated by APACHE-II score, length of ICU, hospital stay or mortality. Conclusion Acute AGE accumulation in ICU patients was shown in this study, although group size was small. This can possibly reflect oxidative stress in ICU patients. Further studies should reveal whether AGE-accumulation will be a useful parameter in ICU patients and whether skin AF has a predictive value for outcome, which was not shown in this small study.

    Polybrominated diphenyl ethers (PBDEs) were analysed in adipose tissue from 92 East Greenland polar bears (Ursus maritimus) sampled during 1999-2001. Mean ΣPBDE concentrations were 70 ng/g lipid weight (lw) (range: 22-192 ng/g lw) and showed no relationship with age or sex. Of the 32 analysed PBDE congeners; BDE47, BDE153, BDE99 and BDE100 dominated, and comprised 99.6% of the ΣPBDE concentration. The ΣPBDE concentration had a highly significant correlation with ΣPCB, ΣCHL, dieldrin, HCB and ΣHCH concentrations. We found a seasonal pattern of median ΣPBDE concentration with 1.2 to 1.8 times higher concentrations in March to July than the rest of the year. The seasonal variation also provides a clue to the seasonal exposure, bio-availability, toxic exposure and degradation. We suggest that future geographical PBDE data comparisons may not need corrections for sex or age, but such data sets should be corrected for seasonal variability, using the presented correctional trigonometric regression. - Mean ΣPBDE concentrations of East Greenland polar bears (Ursus maritimus) were 69.5 ng/g lw (range: 21.7-192 ng/g lw) and showed a seasonal pattern with no relationship with age and sex

    During the nineteenth century, multiple discoveries of moa bones lying on the ground surface in exposed situations generated debate about the recentness of moa extinction. Subsequently, clearance of land for agricultural purposes has probably resulted in the destruction of many surface moa bones and such finds are now rare. The recent discovery of a pair of tibiotarsi from a North Island giant moa (Dinornis novaezealandiae) lying on the forest floor at Aorangi Awarua, Ruahine Range, has allowed the age of two surface moa bones to be tested. Both tibiotarsi were AMS radiocarbon dated and returned ages of 681±28 and 721±29 14C years BP. The 2σ calibrated ranges are statistically the same age and suggest that the bones are from one bird that died sometime between AD 1286 and 1390. Although the bones post-date human settlement of New Zealand, they are not anomalously recent. The results show that, given favourable environmental conditions, moa bones can persist in exposed situations for long periods, and do not necessarily reflect survival of moa into relatively recent times.

    Shoulder outcome scores that include range of motion (ROM) and apprehension signs are limited by the need for direct involvement of the physician. Patient-reported outcome measures are patient centered and self-administered, and they can help physicians track the patient's progress between office visits and for long-term follow-up once the patient has been discharged. Thirty consecutive patients completed a form before their 6-month follow-up after surgery on the labrum or capsule as a result of instability or pain related to instability. The form included bilateral ROM, apprehension, and instability episodes. The same parameters were measured by the physician during the visit. The patient's and physician's responses were compared. The primary outcome was the percentage agreement with exact and approximate agreement. Exact agreement was moderate for forward elevation at 56.6%; fair for abduction and external rotation at 90° at 24.5% and 34%, respectively; and poor for internal rotation at 90° and external rotation with the arm at the side at 2.6% and 12%, respectively. Approximate agreement within a range of positive or negative 20° range was very good for forward elevation (94%), abduction (92%), and external rotation at 90° (87%); moderate for external rotation with the arm at the side; and fair for internal rotation at 90°. There was 70% agreement regarding apprehension, 93% regarding subluxation events, and 100% regarding redislocation events. Some measures of shoulder ROM showed a moderate to high level of agreement between patient-reported measurements and the physician's measurements. This method for short- and long-term follow-up could potentially replace routine clinic visits. Copyright © 2016. Published by Elsevier Inc.

  12. Priming patient safety: A middle-range theory of safety goal priming via safety culture communication.

    2018-05-18

    The aim of this paper is discussion of a new middle-range theory of patient safety goal priming via safety culture communication. Bedside nurses are key to safe care, but there is little theory about how organizations can influence nursing behavior through safety culture to improve patient safety outcomes. We theorize patient safety goal priming via safety culture communication may support organizations in this endeavor. According to this theory, hospital safety culture communication activates a previously held patient safety goal and increases the perceived value of actions nurses can take to achieve that goal. Nurses subsequently prioritize and are motivated to perform tasks and risk assessment related to achieving patient safety. These efforts continue until nurses mitigate or ameliorate identified risks and hazards during the patient care encounter. Critically, this process requires nurses to have a previously held safety goal associated with a repertoire of appropriate actions. This theory suggests undergraduate educators should foster an outcomes focus emphasizing the connections between nursing interventions and safety outcomes, hospitals should strategically structure patient safety primes into communicative activities, and organizations should support professional development including new skills and the latest evidence supporting nursing practice for patient safety. © 2018 John Wiley & Sons Ltd.

    Full Text Available To investigate the incidence and risk factors for retinal detachment (RD after cataract surgery or refractive lens exchange (RLE in patients aged below 61 years.Retrospective medical chart review of 7,886 patients (13,925 eyes who underwent cataract surgery or RLE. Patients aged below 61 years were selected. Age, gender, axial length, follow-up times, and the occurrence of RD were recorded. Additional characteristics documented for RD cases were: history of RD, preexisting retinal findings, laser capsulotomy, status of macula at RD, date and details of RD.From a total of 421 patients (677 eyes aged below 61 years 24 cases of RD were identified, resulting in an overall cumulative incidence per eyes of 3.55%. The mean follow-up time was 45 ± 32.8 months. Ninety-two % of all RDs occurred within 3.6 years from surgery. Axial length had a significant effect on the risk of RD after cataract/ RLE surgery (HR = 1.42, P = 0.0001, 95% CI 1.19-1.69. The highest incidence of RD occurred in the subgroup of 25 to 28.9 mm axial length (10.2%. With an increase in age of ten years, the hazard of postoperative RD was not significantly increased by a factor of 1.50 (P = 0.286, 95% CI 0.71-3.15. The highest incidence of RD occurred in patients aged 50-54 years (5.39%. Compared to females, males had an almost twofold not significant risk of postoperative RD (HR = 1.96, P = 0.123, 95% CI 0.83-4.63. None of the RD cases had a history of RD.Axial length is a significant risk factor for pseudophakic RD. The need for cataract surgery or RLE should be carefully considered in patients with axial lengths between 25 and 29 mm, aged 50-54 years, in males, and in case of preexisting retinal findings.

    To present the results of a patient dose evaluation program in pediatric cardiology and propose local diagnostic reference levels (DRLs) for different types of procedure and age range, in addition to suggesting approaches to correlate patient dose values with patient weight. This study was the first conducted in Latin America for pediatric interventional cardiology under the auspices of the International Atomic Energy Agency. Over three years, the following data regarding demographic and patient dose values were collected: age, gender, weight, height, number of cine series, total number of cine frames, fluoroscopy time (FT), and two dosimetric quantities, dose-area product (DAP) and cumulative dose (CD), at the patient entrance reference point. The third quartile values for FT, DAP, CD, number of cine series, and the DAP/body weight ratio were proposed as the set of quantities to use as local DRLs. Five hundred and seventeen patients were divided into four age groups. Sample sizes by age group were 120 for bands used in Europe, complemented with the values of the ratio between DAP and patient weight. This permits a rough estimate of DRLs for different patient weights and the refining of these values for the age bands when there may be large differences in child size. These DRLs were obtained at the largest pediatric hospital in Chile, with an active optimization program, and could be used by other hospitals in the Latin America region to compare their current patient dose values and determine whether corrective action is appropriate. © 2015 American Association of Physicists in Medicine.

    Full Text Available ABSTRACT In total, 806 eggs of free-range Hassawi indigenous chickens were collected from local farm in Saudi Arabia. Eggs were weekly collected for 11 weeks. Initial egg weight (IEW was recorded, and eggs were graded into four classes (A: 35-40 g, B: 40-45 g, C: 45-50 g, and D: 50-55 g. Eggs were stored for seven days at 75-80% relative humidity and 14-16 C, after which egg weight losses (WL0 were calculated. During incubation, eggs were weighed on days 7 (W7 and 14 (W14, and egg weight losses on days 7 (WL7 and 14 (WL14, and total loss (WL0-14 were calculated. Hatchling weight (CW was measured. The proportion of CW relative to egg weight loss (WL on days0, 7 and 14 days of incubation (CW:WL0; CW:WL7 and CW:WL14, respectively, and break out analyses, fertility (F,total hatchability (HC and hatchability of fertile eggs (HF were also calculated. IEW decreased (p<0.05 with hen age. Stored egg weight (SEW were decreased as hen age increased (p<0.05. WL7, WL14 and WL0-14 showed significant differences (p<0.001 and increased up to first six-week of egg collection time. Hen age affected CW:WL before incubation, and on days 7 and 14 of incubation. Fertility (F was affected (p<0.05 in unpredicted way of increasing and decreasing by hen age. Egg weight class affected SEW, W7and W14 (p<0.001. Class D eggs were the highest weight. Class C eggs had highest HC. In summary, hatching eggs of Hassawi hens were affected by hen age and egg weight in randomly increase and decrease .

    The objective of this study was to identify the optimal frequency range for computing the pressure reactivity index (PRx). PRx is a clinical method for assessing cerebral pressure autoregulation based on the correlation of spontaneous variations of arterial blood pressure (ABP) and intracranial pressure (ICP). Our hypothesis was that optimizing the methodology for computing PRx in this way could produce a more stable, reliable and clinically useful index of autoregulation status. The patients studied were a series of 131 traumatic brain injury patients. Pressure reactivity indices were computed in various frequency bands during the first 4 days following injury using bandpass filtering of the input ABP and ICP signals. Patient outcome was assessed using the extended Glasgow Outcome Scale (GOSe). The optimization criterion was the strength of the correlation with GOSe of the mean index value over the first 4 days following injury. Stability of the indices was measured as the mean absolute deviation of the minute by minute index value from 30-min moving averages. The optimal index frequency range for prediction of outcome was identified as 0.018-0.067 Hz (oscillations with periods from 55 to 15 s). The index based on this frequency range correlated with GOSe with ρ=-0.46 compared to -0.41 for standard PRx, and reduced the 30-min variation by 23%.

    Full Text Available HPV is the most widespread sexually transmitted infection. HPV affects men and women regardless of age and leads to the development of various anogenital area diseases. International studies proved a wide clinical range of the tetravalent HPV vaccine protection and allowed recommending it for the prevention of not only cervical cancer, but also of vulvar, vaginal and anal cancer and anogenital condylomae in patients of both sexes. 42 countries have already introduced national HPV-vaccination programs in compliance with WHO recommendations. Anogenital area cancer morbidity reduction in these countries is expected in 10-15 years. However, a reduction or even complete disappearance of anogenital condylomae among the population has already been noted in a range of countries because the incubation period of this disease is short; this is the first marker of vaccination efficacy in a population.

    Migraine headache is one of the most common primary headache disorders and is three times more prevalent in women than in men, especially during the reproductive ages. The neurobiological basis of the female dominance has been partly established. The present study aimed to investigate the effect of gender on the headache manifestations in migraine patients. The study group consisted of 2082 adult patients from five different hospitals' tertiary care-based headache clinics. The relationship between headache characteristics and gender was evaluated in migraine with aura (MwA) and migraine without aura (MwoA). The duration, severity, frequency of headache and associated symptoms were evaluated in both genders and age-dependent variations and analyzed in two subgroups. Women with migraine were prone to significantly longer duration and intensity of headache attacks. Nausea, phonophobia and photophobia were more prevalent in women. Median headache duration was also longer in women than in men in MwA (p = 0.013) and MwoA (p < 0.001). Median headache intensity was higher in women than in men in MwA (p = 0.010) and MwoA (p = 0.009). The frequency of nausea was significantly higher in women than in men in MwA (p = 0.049). Throbbing headache quality and associated features (nausea, photophobia, and phonophobia) were significantly more frequent in women than in men in MwoA. The gender impact varied across age groups and significant changes were seen in female migraineurs after age 30. No age-dependent variation was observed in male migraineurs. Gender has an influence on the characteristics of the headache as well as on the associated symptoms in migraine patients, and this impact varies across the age groups, particularly in women. © International Headache Society 2014.

    Male hypogonadism is common in the elderly and has been associated with increased risk of mortality. Our objective has been to assess the prevalence of primary and central hypogonadism in elderly male patients admitted to the hospital because of acute illness. We also evaluated the relationships between gonadal dysfunction and in-hospital mortality. 150 patients, aged ≥65 years, admitted during 2010 and 2011 in our geriatric unit, were studied. Serum concentrations total, bioavailable and free testosterone, as well as of follicle-stimulating hormone and luteinizing hormone were quantified in every patient. Hypogonadism was defined by the presence of serum testosterone levels lower than 200 ng/dl. Hypogonadism was found in 80 patients (53.3 %). Serum gonadotropin concentrations were elevated in 43.7 % of these patients, whereas 41.3 % of hypogonadic patients showed normal and 15 % low gonadotropin concentrations. Respiratory tract infection and congestive heart failure were the main causes of hospitalization in hypogonadal men, whereas acute cerebrovascular disease was the main reason for admission in eugonadal patients. Of the 13 patients who died during hospitalization, 12 were hypogonadic. Patients who died showed significantly lower serum levels of total, free and bioavailable testosterone than those found in patients who survived. Our results show that about half of patients admitted for acute illness have hypogonadism, mainly of non-hypergonadotropic type. Gonadal hypofunction is significantly related with in-hospital mortality. A low value of serum testosterone may be a predictor for mortality in elderly male patients.

    PurposeTo analyze choroidal neovasularization (CNV) activity and recurrence patterns in patients with neovascular age-related macular degeneration (nAMD) treated with ranibizumab, and the correlation with individual intraocular vascular endothelial growth factor (VEGF) suppression time (VST).MethodsPost-hoc analysis of data from a prospective, non-randomized clinical study. Patients with nAMD treated with ranibizumab on a pro re nata regimen. Disease activity was analyzed monthly by spectral-domain optical coherence tomography and correlated with VSTs.ResultsOverall, 73 eyes of 73 patients were included in the study with a mean follow-up of 717 days (range: 412-1239 days). Overall, the mean CNV-activity-free interval was 76.5 days (range: 0-829 days). The individual range of the length of dry intervals was high. A total of 42% of patients had a range of more than 90 days. Overall, 16% of patients showed persistent activity. And 12% stayed dry after the initial ranibizumab treatment. No significant correlation was found between the CNV-recurrence pattern and VST (P=0.12).ConclusionsCNV activity in nAMD is irregular, which is reflected in the range of the duration of dry intervals and late recurrences. The biomarker VST solely seems not to be sufficient to explain recurrence pattern of CNV in all AMD patients.

    There have been few reports concerning radioactive iodine therapy (RI therapy) for Graves' disease in children, even in the United States of America (USA), and there have been no reports of such treatment in Japan. We evaluated the short-term results of RI therapy for Graves' disease aged 18 or younger. A total of 36 patients (10 male and 26 female) with Graves' disease, aged 18 and younger (range, 13 to 18 years; mean age, 15.8±1.5 years), received RI therapy on an outpatient basis at our clinic between July 1999 and July 2005. The mean interval from initiation of an antithyroid drug (ATD) to RI therapy was 25.3±21.5 months (range, 1 to 78 months). Twenty patients received therapy once, 14 twice, and 2 three times. The mean initial dose of radioactive iodine was 7.8±2.9 mCi (range, 3.6 to 13.0 mCi) and the mean total dose was 12.3±7.7 mCi (range, 3.6 to 29.8 mCi). The mean estimated weight of the thyroid gland was 42.6±23.4 g (range, 15.5 to 99.4 g) before RI therapy and 7.1±3.0 g (range, 2.0 to 13.6 g) after RI therapy. The mean follow-up period after RI therapy was 41.1±18.0 months (range, 6 to 71 months). Currently, 15 patients (42%) have hypothyroidism, 8 (22%) have subclinical hypothyroidism, 5 (14%) have euthyroidism, and 8 (22%) have subclinical hyperthyroidism. Patients taking thyroid hormone were considered hypothyroid. Patients with subclinical hypothyroidism are currently being monitored without treatment. No patients with subclinical hyperthyroidism are taking an ATD or KI (potassium iodide). A total of 36 patients with Graves' disease, aged 18 and younger, received RI therapy, and the short-term outcome in these patients were favorable. However, prolonged follow-up observation is required to confirm long-term safety. (author)

    The risk of breast cancer (BC) increases in parallel with increasing age. Despite the increased disease burden in elderly patients, there is still a great uncertainty regarding "how to manage" BC in aging-population. The purpose of this study was to investigate the clinicopathological features and treatment approaches of patients with BC aged 70 years or over. The medical records of 4413 patients with BC followed between 1994-2015 were retrospectively analyzed. Of the 4413 patients, 238 with stage I to III disease aged 70 years or over at BC diagnosis were enrolled into this study. Patients were divided into 2 groups according to the age as group 1 (70-79 years, N=192) and group 2 (80 or over, N=46). Clinicopathological features of patients including tumor histology, grade, estrogen (ER) and progesterone receptor (PgR) status, human epidermal growth factor receptor 2 (HER2) status, tumor size, lymph node involvement (LNI), lymphovascular invasion (LVI), perineural invasion (PNI), clinical stage, type of surgery, treatments and comorbid diseases were evaluated. The median age was 74 for group 1 (range 70-79) and 82 for group 2 (range 80-92). Excluding tumor size and grade, no statictically significant difference was found between the two groups according to histopathological characteristics. Patients in group 2 had more commonly larger T stage (T4), and less frequently presented with grade I tumor (p=0.014 and p=0.044, respectively). Modified radical mastectomy and adjuvant chemotherapy were more commonly performed in group 1 (p=0.001 and p=0.001, respectively). In contrast, neoadjuvant treatment was more frequently applied in group 2 (p=0.003). There was no difference in disease-free survival (DFS) between the groups (p=0.012), however, median overall survival (OS) was significantly higher in group 1 (p=0.03). Excluding the tumor grade and tumor size, both groups had similar histopathological features. However, patients aged between 70-79 years were likely to

    Full Text Available Handball activity involves cardiac changes and demands a mixture of both eccentric and concentric remodeling within the heart. This study seeks to explore heart performance and cardiac remodeling likely to define cardiac parameters which influence specific performance in male handball players across different age ranges. Forty three players, with a regular training and competitive background in handball separated into three groups aged on average 11.78 ± 0.41 for youth players aka "schools", "elite juniors" 15.99 ± 0.81 and "elite adults" 24.46 ± 2.63 years, underwent echocardiography and ECG examinations. Incremental ergocycle and specific field (SFT tests have also been conducted. With age and regular training and competition, myocardial remodeling in different age ranges exhibit significant differences in dilatation's parameters between "schools" and "juniors" players, such as the end-diastolic diameter (LVEDD and the end-systolic diameter of the left ventricle (LVESD, the root of aorta (Ao and left atrial (LA, while significant increase is observed between "juniors" and "adults" players in the interventricular septum (IVS, the posterior wall thicknesses (PWT and LV mass index. ECG changes are also noted but NS differences were observed in studied parameters. For incremental maximal test, players demonstrate a significant increase in duration and total work between "schools" and "juniors" and, in total work only, between "juniors" and "seniors". The SFT shows improvement in performance which ranged between 26.17 ± 1.83 sec to 31.23 ± 2.34 sec respectively from "seniors" to "schools". The cross-sectional approach used to compare groups with prior hypothesis that there would be differences in exercise performance and cardiac parameters depending on duration of prior handball practice, leads to point out the early cardiac remodeling within the heart as adaptive change.

For incremental maximal test, players demonstrate a significant increase in duration and total work between “schools” and “juniors” and, in total work only, between “juniors” and “seniors”. The SFT shows improvement in performance which ranged between 26.17±1.83 sec to 31.23±2.34 sec respectively from “seniors” to “schools”. The cross-sectional approach used to compare groups with prior hypothesis that there would be differences in exercise performance and cardiac parameters depending on duration of prior handball practice, leads to point out the early cardiac remodeling within the heart as adaptive change.

    In light of new techniques for measuring circulating thyroid hormones and for studying the thyroid gland, we present our experience with 35 patients with solitary autonomous nodules of the thyroid to define more precisely the clinical course of patients with this disorder. The patients ranged in age from 19 to 80 years and 31 of the 35 were female. Younger patients were generally euthyroid and sought attention because of a thyroid mass; virtually all older patients were hyperthyroid. Eighteen had obvious clinical features of hyperthyroidism and 5 over age 70 had apathetic hyperthyroidism; all 5 of the elderly and 13 of the 18 under age 70 had elevated thyroxine (T 4 ) and triiodothyronine (T 3 ) levels. Isolated elevation of T 3 and elevated basal metabolic rate were observed in 5 previously untreated clinically hyperthyroid young patients. In each of these, thyroid uptake of 131 I was not suppressible with exogenous T 3 and BMR was elevated in those tested. Two elderly patients, who had previously been treated for conventional hyperthyroidism with radioactive iodine, had T 3 toxicosis when hyperthyroidism recurred. There was a strong positive correlation between the age of the patient, the size of the nodule and the thyroid functional state. The mean area of the nodules projected on 131 I rectilinear scan for euthyroid patients was 5.1 cm 2 . The mean area of the nodules in hyperthyroid subjects was significantly higher, 13.4 cm 2 in patients with T 3 toxicosis and 19.3 cm 2 in subjects with conventional hyperthyroidism. Progression from a euthyroid state to hyperthyroidism was observed in four patients. One of these became thyrotoxic within days after an injection of iodinated contrast medium. Spontaneous resolution of nodules occurred in two patients

    To report alterations in visual acuity and visual pathway structure over an interval of 1-3 years in a cohort of children, adolescents and young adults who have Wolfram syndrome (WFS) and to describe the range of disease severity evident in patients with WFS whose ages differed by as much as 20 years at first examination. Annual, prospective ophthalmological examinations were performed in conjunction with retinal nerve fibre layer (RNFL) analysis. Diffusion tensor MRI-derived fractional anisotropy was used to assess the microstructural integrity of the optic radiations (OR FA). Mean age of the 23 patients with WFS in the study was 13.8 years (range 5-25 years). Mean log minimum angle resolution visual acuity was 0.66 (20/91). RNFL thickness was subnormal in even the youngest patients with WFS. Average RNFL thickness in patients with WFS was 57±8 µ or ~40% thinner than that measured in normal (94±10 µ) children and adolescents (P<0.01). Lower OR FA correlated with worse visual acuity (P=0.006). Subsequent examinations showed declines (P<0.05) in visual acuity, RNFL thickness and OR FA at follow-up intervals of 12-36 months. However, a wide range of disease severity was evident across ages: some of the youngest patients at their first examination had deficits more severe than the oldest patients. The genetic mutation of WFS causes damage to both pregeniculate and postgeniculate regions of the visual pathway. The damage is progressive. The decline in visual pathway structure is accompanied by declines of visual function. Disease severity differs widely in individual patients and cannot be predicted from their age.

    Purpose: To present the results of a patient dose evaluation program in pediatric cardiology and propose local diagnostic reference levels (DRLs) for different types of procedure and age range, in addition to suggesting approaches to correlate patient dose values with patient weight. This study was the first conducted in Latin America for pediatric interventional cardiology under the auspices of the International Atomic Energy Agency. Methods: Over three years, the following data regarding demographic and patient dose values were collected: age, gender, weight, height, number of cine series, total number of cine frames, fluoroscopy time (FT), and two dosimetric quantities, dose-area product (DAP) and cumulative dose (CD), at the patient entrance reference point. The third quartile values for FT, DAP, CD, number of cine series, and the DAP/body weight ratio were proposed as the set of quantities to use as local DRLs. Results: Five hundred and seventeen patients were divided into four age groups. Sample sizes by age group were 120 for <1 yr; 213 for 1 to <5 yr; 82 for 5 to <10 yr; and 102 for 10 to <16 yr. The third quartile values obtained for DAP by diagnostic and therapeutic procedures and age range were 1.17 and 1.11 Gy cm{sup 2} for <1 yr; 1.74 and 1.90 Gy cm{sup 2} for 1 to <5 yr; 2.83 and 3.22 Gy cm{sup 2} for 5 to <10 yr; and 7.34 and 8.68 Gy cm{sup 2} for 10 to <16 yr, respectively. The third quartile value obtained for the DAP/body weight ratio for the full sample of procedures was 0.17 (Gy cm{sup 2}/kg) for diagnostic and therapeutic procedures. Conclusions: The data presented in this paper are an initial attempt at establishing local DRLs in pediatric interventional cardiology, from a large sample of procedures for the standard age bands used in Europe, complemented with the values of the ratio between DAP and patient weight. This permits a rough estimate of DRLs for different patient weights and the refining of these values for the age bands when there

    Full Text Available Background: Neck pain has been reported as a prevalent musculoskeletal disorder globally with more than half of the general population being affected once or more within their life span. Methods: A randomized clinical trial research design was used which investigated the immediate effect of cervical manipulation on neck pain and cervical range of motion among patients with chronic mechanical neck pain. 20 male and female participants between the ages of 26 to 60 years with chronic mechanical neck pain attending physiotherapy clinics were recruited. They were randomly assigned into two groups (A and B of 10 patients each. Group A received soft tissue massage, and cervical manipulation and group B served as the control group, and they received only soft tissue massage. There were two outcomes measured; Pain intensity was rated using visual analog scale (VAS before and immediately after the intervention. Pre and Post intervention measurements of cervical spine range of motion using Goniometer were also taken. Results: Findings of the study revealed significant immediate improvement of pain and Cervical Range of Motions (p<0.05 in all dimensions in the experimental group while Pain, flexion and right side Cervical flexion significantly improved in the control group. It was also found out after comparing the outcomes between the two groups that, the experimental group had significantly (p<0.05 better improvement than the control group in post-intervention pain, cervical flexion, cervical extension and cervical (right and left lateral rotations. Conclusion: Cervical manipulation is effective in immediate pain relief and improvement in cervical range of motion in patients with mechanical neck pain

    Physiological characteristics, such as blood chemistry values, are valuable for evaluating the health of the animals. To our knowledge, these values have never been reported for the free-ranging Asiatic black bear ( Ursus thibetanus; ABB). Thus, 28 blood chemistry values from 50 free-ranging ABBs captured in Jirisan National Park, Republic of Korea, from 2005 to 2016 were evaluated. The aim of this study was to establish blood chemistry reference values for the free-ranging ABBs during both the hibernating and nonhibernating seasons. During hibernation, mean values of creatinine (CRE), total cholesterol, total protein (TP), albumin (ALB), triglycerides, and Mg were significantly higher than those during nonhibernation; however, mean values of blood urea nitrogen, urea nitrogen to creatinine (U/C) ratio, inorganic phosphorous (IP), aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase, lactate dehydrogenase (LDH), high-density lipoprotein cholesterol, and alkaline phosphatase (ALP) were significantly lower. Age differences (young vs. adult) were found in IP, LDH, TP, and ALB values during hibernation and in the U/C ratio, Ca, IP, ALP, creatine kinase myocardial band, CRE, total bilirubin, and uric acid values during nonhibernation. However, there were no sex differences (male vs. female).

    Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P arthroscopy should be considered a valid treatment option when treating hip pain in patients aged 50 years or older with a Tönnis arthritic grade of 0 or 1.

    Thirty-eight patients with prostatic cancer treated with radiotherapy giving a mean dose of 60.7 Gy between 1992 and 1997 at Shikoku Cancer Center Hospital were reviewed and the treatment outcomes were investigated retrospectively. About two-third of the patients were treated with radiation by linear accelerator with 40 to 46 Gy to the whole pelvis and with 20 to 26 Gy boost to the prostate area and the other one-third were treated only to the prostate area. For almost patients, external beam radiotherapy in combination with endocrine therapy was used. The median duration of follow-up was 36 months. Overall 5-year survival and 5-year relapse-free survival rate were 65.8%, and 88.9%, respectively. Severe rectal late morbidity (over grade 3) according to RTOG grading system were seen in one (2.6%). Although the number of cases was rather small and the follow-up duration was rather short, conventional external beam radiotherapy in combination with endocrine therapy may contribute to the survival benefit of patients with prostatic cancer in aged 75 or older. Radiotherapy for elderly prostatic cancer patients should be treated with an effort to decrease the late morbidity and not to deteriorate the QOL of the patients, because many patients were died of other causes than cancer.

    This study aimed to assess the cognitive functions and cerebral blood flow measured with arterial spin labeling (ASL) and their possible correlations with vascular age in untreated middle-aged patients with grade 1-2 essential arterial hypertension (EAH). We examined 73 subjects aged 40-59 years (33 with EAH and 40 healthy volunteers [controls]). Neuropsychological assessment included Montreal Cognitive Assessment (MoCA), Trail Making test (part A and part B), Stroop Color and Word Test, verbal fluency test (phonemic verbal fluency and semantic verbal fluency), 10‑item word list learning task. All subjects underwent brain MRI. MRI protocol included ASL. Vascular age was calculated by two techniques - using Framingham Heart Study risk tables and SCORE project scales. Patients with EAH had lower performance on phonemic verbal fluency test and lower mean MoCA score (29.2±1.4 vs. 28.1±1.7 points) compared to controls (13.4±3.2, р=0.002; 29.2±1.4, p=0.001, respectively). White matter hyperintensities (WMH) were present in 7.5 % controls and in 51.5 % EAH patients (р=0.0002). Cerebral blood flow (CBF) in EAH patients was lower in both right (39.1±5.6 vs. 45.8±3.2 ml / 100 g / min) and left frontal lobes of the brain (39.2±6.2 и 45.2±3.6 ml / 100 g / min, respectively) compared to controls (р.

    Full Text Available Objective: Percutaneous nephrolithotomy (PNL is a minimally invasive method used safely in surgical treatment of kidney stones in the world. The first PNL surgery performed in our clinic in March 1998 and first PNL surgery was performed in June 2000 over the age of seventy which was bilaterally side. In our study, PNL operations performed for 75 years and older patients were examined. Methods: PNL operations were performed under the general anesthesia. After cystoscopy in the supine position, ureteral catheter was inserted accompanied by C-arm fluoroscopy. Afterwards, patients were taken prone position then we entered into the kidney with a metal needle with fluoroscopic on. We dilated the entrance with Amplatzer renal dilatators set until the 30 F. After the procedure, the nephrostomy catheter was placed in the renal sheath. 4 mm residual fragments after the PNL operation were accepted as clinically insignificant stone residues (CIRF. Results: 3003 PNL procedures were performed between dates March 1998 - December 2014 in total 16 years. 28 patients of total were 75 years and over. 29 PNL surgeries performed to these patients, including one bilateral PNL procedure. Mean age was 79.36 years (75-88. Twenty (74% of the patients were concluded stone free. 2 patients had tubeless PNL surgery. There was no another complication. Conclusion: PNL is a minimally invasive method has became advantageous according to open surgery because of higher safety, lower complication rates, shorter hospitalization stay, more patient comfort and higher stone free rates. PNL is a safe and effective method in the surgical treatment of urinary tract stone diseases.

    Hereditary haemorrhagic telangiectasia (HHT) is inherited as an autosomal dominant trait with varying penetrance and expressivity. Some of the most devastating consequences of this disease result from cerebral vascular malformations that manifest themselves in either arteriovenous fistulae (AVF), small nidus-type arteriovenous malformations (AVM) or micro-AVMs with a nidus less than 1 cm in size. The purpose of this study was to compare the phenotypes of CNS-manifestations of HHT with the age of the patient. The charts and angiographic films of 50 patients diagnosed with HHT according to the Curacao criteria were retrospectively evaluated concerning age of onset of symptoms, or, if not applicable of first consultation. The files were reviewed for clinical presentation, family and personal history, while the patients' angiograms were analysed with respect to the number of lesions (single and multiple), the location (superficial supratentorial, deep supratentorial, infratentorial, and spinal), and type of lesion (fistulous AVM, nidus-type AVM, and micro-AVM). A total of 75 central nervous system manifestations of HHT were found. Lesions included seven spinal cord AVFs that were all present in the paediatric age group (mean age: 2.2 years), 34 cerebral AV fistulae, all but two affected patients were less than 6 years (mean age 3.0). Sixteen nidus type AVMs (mean age: 23.1 years) and 18 micro-AVMs (mean age: 31.8 years) were found. HHT displays an age-related penetrance of clinical manifestations. Since members of the same family can present with completely different phenotypes of this disease there seems to be no relationship between the type of mutation and the phenotype of the disease. Since there seems to be a continuum of vascular abnormalities (from large fistulous areas to small AVMs and micro-AVMs) associated with HHT, the most likely determinating factor of the HHT phenotype is the timing of the revealing event in relation to the maturity of the vessel

    Purpose: To analyze the use of radiation therapy following local excision of invasive localized breast cancer and subsequent survival by 5-year age category. Methods: Data for 27,399 women diagnosed with localized stage of breast cancer and treated with local excision surgery from 1983 through 1992 were collected and provided by the national Surveillance, Epidemiology, and End Results (SEER) program. Use of radiation therapy was analyzed by race, ethnic background, geographic location, and age at diagnosis. Survival for women treated with local excision plus radiation therapy was compared to that of women treated with local excision alone for each 5-year age category. Results: Subjects in older age groups were significantly less likely (p < 0.001) to receive radiation following local excision compared to younger age groups. Statistically significant survival advantages were conferred on women receiving radiation therapy in each 5-year age category from age 35 to 84 years (ranging from p = 0.02 to p < 0.0001). Conclusion: While the use of radiation therapy following local excision of early-stage breast tumors drops significantly in older age groups, women aged 35-84 years receiving radiation therapy had significant reductions in mortality. These results did not appear to be influenced by the presence of mortal comorbid conditions. These results strongly suggest the need to consider carefully patient characteristics other than age in deciding the course of treatment for early-stage breast cancer

    Full Text Available Perforation is a rare complication of gastric carcinoma, and it occurs in less than 5% of all gastric carcinoma cases and in less than 1% within all acute abdomen cases. The diagnosis of malignancy is usually not validated preoperatively. In previous reported English literature, all patients with perforated gastric cancer have the feature of old age. This feature might be able to guide the surgeon to impress the differential diagnosis of malignancy before or during the emergent operation of gastric perforation.This 32-year-old male patient suffered from sudden onset of epigastric pain. We performed emergent operation under the impression of hollow organ perforation. The postoperative pathologic report of gastric ulcer revealed gastric carcinoma. We performed second-stage operation of total gastrectomy with D2 lymphadenectomy smoothly 7 days later. As we know, this is the youngest patient having the condition of perforated gastric carcinoma reported in the literature. This case reminds us that it is possible for perforated gastric carcinoma to occur in young-age patients. Keywords: Gastric cancer, Acute abdomen, Gastric perforation

    There are few Spanish studies on acute poisoning in the elderly despite the associated risk factors of this group of patients. Retrospective descriptive study of acute poisonings treated in the Emergency Service of the University Hospital of Zaragoza from 1995 to 2009 on patients 65 years old or older. A total of 762 patients were selected in the study (4.74% of all acute poisonings) with a mean age of 74.16 (SD ± 6) years. Ingestion was the major route of exposure (85%) and alcohol overdose (28,7%) was the most frequent type of poisoning. A trend was also observed showing a lower emetic treatment and gastric lavage and an increase in activated charcoal. Benzodiazepines (14.3%) and toxic household products (11%) with caustic properties were also the main toxics found in the study. Acute poisonings in the elderly required more hospitalizations, have a higher mortality and more autolytic attempts which result in death.

    Full Text Available Background: The outcome of treatment of hip fractures in different age groups in the elderly population is largely unknown. Hence, we stratified elderly patients with hip fracture into age groups and compared the prognosis in various age groups. Materials and Methods: Among 459 patients with hip fracture treated at our hospital from 1997, 430 patients aged 65 years or above at the time of injury were studied. The patients comprised 98 males and 332 females and the ages at injury ranged from 65 to 103 years (mean 83.4 years. There were 167 cases of femoral neck fracture and 263 cases of trochanteric fractures. Surgery was performed in 383 cases, while 47 cases were treated conservatively. The subjects were classified by age into young-old for those aged 65-74 years (group A, n = 55, middle-old for those aged 75-84 years (group B, n = 172, old-old for those aged 85-94 (group C, n = 180, and oldest-old for those aged 95 years or above (group D, n = 23. The functional and survival prognosis at discharge in each group was investigated. Results: Numbers of patients who were ambulatory at discharge among those ambulatory before injury were 43 of 49 (87.8% in group A, 113 of 152 (74.3% in group B, 86 of 138 (62.3% in group C, and 5 of 14 (35.7% in group D, showing worse recovery of walking ability as age advanced. Among those ambulatory before injury, 42 patients in group A, 139 patients in group B, 130 patients in group C, and 12 patients in group D underwent surgery and of these patients, 38 patients (90.5% in group A, 109 patients (78.4% in group B, 83 patients (63.8% in group C, and 5 patients (41.7% in group D were ambulatory at discharge. On the other hand, the numbers of patients who were ambulatory at discharge among those receiving conservative treatment were 5 of 7 (71.4% in group A, 4 of 13 (30.8% in group B, 3 of 8 (37.5% in group C, and 0 of 2 (0% in group D, showing better walking ability in surgical patients than in conservatively treated

    The purpose of this study was to assess the efficacy and problems of radiotherapy for patients aged 85 or older. Forty-five patients were assessed (oldest old group): They were 85 years of age or older and had received radiotherapy between September 2002 and September 2005. Sixty-nine patients, 75 years of age at the start of radiotherapy, were also assessed (old group). In the oldest old group, there were 21 men and 24 women, and median age was 87 years (range; 85-99). The sites of disease were: 10 in head and neck, 5 in lung, 5 in malignant lymphoma, 4 in skin, 4 in esophagus, 2 in breast, 2 in uterine cervix, 2 in rectum, 2 in soft tissue, 2 in metastatic bone tumor, 7 in others. The treatment was deemed curative in 49%, palliative in 40%, and others in 11%. Treatment fields were limited due to performance status (PS) or age in 13 patients. The rate of treatment completion was 91% (41/45). Eleven of 26 inpatients were admitted because of difficulty in hospital visit. Seventeen of 19 outpatients needed familial escort. Of patients completed radiotherapy, 47% of the patients achieved complete response (CR), 37% achieved partial response (PR), and 16% achieved no change (NC) in the group of curative radiotherapy, and 88% of the patients achieved effective response, and only 2 cases resulted in ineffective response in the group of palliative radiotherapy. While only one patient received grade 3 dermatitis and mucositis, other patients received grade 2 and below adverse events. Three patients resulted in deterioration of PS, and 2 patients deteriorated dementia. Although higher rates in female patients, worse PS, and limitation of treatment field were seen in the oldest old group, there were no significant difference in terms of the rate of treatment completion, effectiveness, and adverse events between the two groups. Our study showed radiotherapy is effective and well tolerated in patients aged 85 or older. Considering the oldest old requiring radiotherapy

    (1) The correlations between: (1.1) various aspects of religiousness and (1.2) age, anxiety-state, anxiety-trait, locus of control, and, in the group of patients with shizophrenia: span of treatment, rate of therapy, ego psychopathology, paranoid and depression dimensions, self-rating of state of self-feeling, state of feeling of illness, and quality of life and (2) the comparison of various aspects of religiousness of patients with schizophrenia and healthy people were studied. The Scale of Christian Religiousness, Individual Religiousness Scale, Intrinsic, Extrinsic and Quest Religious Orientation Scales, Scale of Fundamentalism, State-Trait Anxiety Inventory, Rotter's questionnaire of locus of control, Scharfetter's questionnaire of ego psychopathology, Paranoid-Depresivity Scale-abridgment, Frankfurt Self-feeling Scale-abridgment, visual analogy of self-feeling, visual analogy of feeling of illness, and questionnaire of quality of life (WHOQOL-BREF) were used in the study. 91 adults both of sexes, 60 patients with a diagnosis of schizophrenia according to ICD-10 and DCR-10 in the diagnostic group and 31 healthy persons were studied. It was noticed that: (1) various correlations are manifested between religiousness and psychopathology of patients with schizophrenia; (2) patients diagnosed as having schizophrenia have a significantly higher level of extrinsic religiousness and fundamentalism than healthy individuals; (3) many results pointed out in the bibliography had no verification in these studies. Intrinsic, extrinsic, quest, and orthodox religiousness and fundamentalism realize significant functions in psychopathology of schizophrenia disorder. The knowledge about religiousness of schizophrenia patients can be important for diagnostic and therapeutic processes of the disorder.

    A wind tunnel test was conducted to obtain vortex velocity signatures over a wide parameter range encompassing the data conditions of several previous researchers while maintaining a common instrumentation and test facility. The generating wing panel was configured with both a revolved airfoil tip shape and a square tip shape and had a semispan aspect of 4.05/1.0 with a 121.9 cm span. Free stream velocity was varied from 6.1 m/sec to 76.2 m/sec and the vortex core velocities were measured at locations 3, 6, 12, 24 and 48 chordlengths downstream of the wing trailing edge, yielding vortex ages up to 2.0 seconds. Wing pitch angles of 6, 8, 9 and 12 deg were investigated. Detailed surface pressure distributions and wing force measurements were obtained for each wing tip configuration. Correlation with vortex velocity data taken in previous experiments is good. During the rollup process, vortex core parameters appear to be dependent primarily on vortex age. Trending in the plateau and decay regions is more complex and the machanisms appear to be more unstable.

    The efficacy and tolerability of vitamin K antagonists (VKAs) depends on the quality of anticoagulant control, reflected by the mean time in therapeutic range (TTR) of international normalized ratio 2.0 to 3.0. In the present study, we aimed to investigate the association between TTR and change in TTR (ΔTTR) with the risk of mortality and clinically significant events in a consecutive cohort of atrial fibrillation (AF) patients. We included 1361 AF patients stable on VKAs (international normalized ratio 2.0-3.0) during at least the previous 6 months. After 6 months of follow-up we recalculated TTR, calculated ΔTTR (ie, the difference between baseline and 6-month TTRs) and investigated the association of both with the risk of mortality and "clinically significant events" (defined as the composite of stroke or systemic embolism, major bleeding, acute coronary syndrome, acute heart failure, and all-cause deaths). The median ΔTTR at 6 months of entry was 20% (interquartile range 0-34%), 796 (58.5%) patients had a TTR reduction of at least 20%, while 330 (24.2%) had a TTR <65%. During follow-up, 34 (2.5% [4.16% per year]) patients died and 61 (4.5% [7.47% per year]) had a clinically significant event. Median ΔTTR was significantly higher in patients who died (35.5% vs 20%; P = 0.002) or sustained clinically significant events (28% vs 20%; P = 0.022). Based on Cox regression analyses, the overall risk of mortality at 6 months for each decrease point in TTR was 1.02 (95% CI, 1.01-1.04; P = 0.003), and the risk of clinically significant events was 1.01 (95% CI, 1.00-1.03; P = 0.028). Patients with TTR <65% at 6 months had higher risk of mortality (hazard ratio = 2.96; 95% CI, 1.51-5.81; P = 0.002) and clinically significant events (hazard ratio = 1.71; 95% CI, 1.01-2.88; P = 0.046). Our findings suggest that in AF patients anticoagulated with VKAs, a change in TTR over 6 months (ie, ΔTTR) is an independent risk factor for mortality and clinically significant events

    Purpose: To review the outcomes and tolerability of full-dose chemoradiation in elderly patients aged 75 years or older with localized pancreatic cancer. Methods and Materials: We retrospectively reviewed patients aged 75 years or older with nonmetastatic pancreatic cancer treated with chemoradiation therapy at two institutions from 2002 to 2007. Patients were analyzed for treatment toxicity, local recurrences, distant metastases, and survival. Results: A total of 42 patients with a median age of 78 years (range, 75-90 years) who received chemoradiation therapy for pancreatic cancer were identified. Of the patients, 24 had locally advanced disease treated with definitive chemoradiation, and 18 had disease treated with surgery and chemoradiation. Before chemoradiotherapy, the mean Eastern Cooperative Oncology Group performance status was 1.0 ± 0.8, and the mean 6-month weight loss was 5.3 ± 3.8 kg. The mean radiation dose delivered was 48.1 ± 9.2 Gy. All patients received fluoropyrimidine-based chemotherapy concurrently with radiotherapy. In all, 8 patients (19%) were hospitalized, 7 (17%) had an emergency room visit, 15 (36%) required a radiation treatment break, 3 (7%) required a chemotherapy break, 9 (21%) did not complete therapy, and 22 (49%) had at least one of these adverse events. The most common toxicities were nausea, pain, and failure to thrive. Median overall survival was 8.6 months (95% confidence interval, 7.2-13.1) in patients who received definitive chemoradiation therapy and 20.6 months (95% confidence interval, 9.5-∞) in patients who underwent resection and chemoradiation therapy. Conclusions: In this dataset of very elderly patients with pancreatic cancer and good Eastern Cooperative Oncology Group performance status, outcomes after chemoradiotherapy were similar to those among historic controls for patients with locally advanced and resected pancreatic cancer, although many patients experienced substantial treatment-related toxicity.

    The dense plasma focus is blessed not only with copious multi-radiations ranging from electron and ion beams, x-rays both soft and hard, fusion neutrons D-D and D-T but also with the property of enhanced compression from radiative collapse leading to HED (high energy density) states. The Lee code has been used in extensive systematic numerical experiments tied to reality through fitting with measured current waveforms and verified through comparison of measured and computed yields and measurements of multi-radiation. The studies have led to establishment of scaling laws with respect to storage energy, discharge current and pinch currents for fusion neutrons, characteristic soft x-rays, all-line radiation and ion beams. These are summarized here together with a first-time presentation of a scaling law of radiatively enhanced compression as a function of atomic number of operational gas. This paper emphasizes that such a broad range of scaling laws signals the coming of age of the DPF and presents a reference platform for planning the many potential applications such as in advanced SXR lithography, materials synthesizing and testing, medical isotopes, imaging and energy and high energy density (HED).

    Full Text Available Abstract Background The aims of this study were to evaluate the construct validity (known group, concurrent validity (criterion based and test-retest (intra-rater reliability of manual goniometers to measure passive hip range of motion (ROM in femoroacetabular impingement patients and healthy controls. Methods Passive hip flexion, abduction, adduction, internal and external rotation ROMs were simultaneously measured with a conventional goniometer and an electromagnetic tracking system (ETS on two different testing sessions. A total of 15 patients and 15 sex- and age-matched healthy controls participated in the study. Results The goniometer provided greater hip ROM values compared to the ETS (range 2.0-18.9 degrees; P P Conclusions The present study suggests that goniometer-based assessments considerably overestimate hip joint ROM by measuring intersegmental angles (e.g., thigh flexion on trunk for hip flexion rather than true hip ROM. It is likely that uncontrolled pelvic rotation and tilt due to difficulties in placing the goniometer properly and in performing the anatomically correct ROM contribute to the overrating of the arc of these motions. Nevertheless, conventional manual goniometers can be used with confidence for longitudinal assessments in the clinic.

    Proteinuria is an established risk factor for progression of renal disease, including diabetic nephropathy. The predictive power of proteinuria, especially nephrotic range proteinuria, for progressive renal deterioration has been well demonstrated in diabetic patients with normal to relatively preserved renal function. However, little is known about the relationship between severity of proteinuria and renal outcome in pre-dialysis diabetic patients with severely impaired renal function. 125 incident dialysis patients with type 2 diabetes were identified. This study was aimed at retrospectively evaluating the impact of nephrotic range proteinuria (urinary protein-creatinine ratio above 3.5 g/gCr) on renal function decline during the 3 months just prior to dialysis initiation. In total, 103 patients (82.4 %) had nephrotic range proteinuria. The median rate of decline in estimated glomerular filtration rate (eGFR) in this study population was 0.98 (interquartile range 0.51-1.46) ml/min/1.73 m(2) per month. Compared to patients without nephrotic range proteinuria, patients with nephrotic range proteinuria showed significantly faster renal function decline (0.46 [0.24-1.25] versus 1.07 [0.64-1.54] ml/min/1.73 m(2) per month; p = 0.007). After adjusting for gender, age, systolic blood pressure, serum albumin, calcium-phosphorus product, hemoglobin A1c, and use of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker, patients with nephrotic range proteinuria showed a 3.89-fold (95 % CI 1.08-14.5) increased risk for rapid renal function decline defined as a decline in eGFR ≥0.5 ml/min/1.73 m(2) per month. Nephrotic range proteinuria is the predominant renal risk factor in type 2 diabetic patients with severely impaired renal function receiving pre-dialysis care.

    Clinicians increasingly suggest assessment and treatment of the cervical spine in patients with temporomandibular dysfunction (TMD); however, few studies have investigated upper cervical spine mobility in people who suffer from TMD. The purpose of this study was to investigate whether patients with TMD pain (with or without headache) present with upper cervical spine impairment when compared with asymptomatic subjects. A single blind examiner evaluated cervical range of motion (ROM) measures including axial rotation during the flexion-rotation test (FRT) and sagittal plane ROM. Twenty asymptomatic subjects were compared with 37 subjects with pain attributed to TMD, confirmed by the Revised Research Diagnostic Criteria. Subjects with TMD were divided according to the presence of headache (26 without headache TMDNHA, 11 with headache TMDHA). One-way analysis of variance and planned orthogonal comparisons were used to determine differences in cervical mobility between groups. All subjects with TMD were positive on the FRT with restricted ROM, while none were in the control group. The analysis of variance revealed significant differences between groups for the FRT F(2,54) = 57.96, Pheadache. Only subjects with TMD and headache had impairment of cervical spine sagittal plane mobility. This study provides evidence for the importance of examination of upper cervical mobility determined by the FRT in patients who suffer from TMD.

    Cystic fibrosis (CF) is the most common autosomal recessive disease in Caucasians. Although most cases are diagnosed in childhood, diagnosis in adults is apparently increasing. Evaluate the adult population with CF, comparing patients who were diagnosed before and after 18 years of age. Retrospective analysis of patients followed in three main medical centres in Portugal in 2012. Comparison of two groups: G1 - patients diagnosed at <18 years and G2 - patients diagnosed at ≥18 years. 89 adults were identified: 61.8% in G1, 38.2% in G2. Gender distribution was similar in both groups. Average age in G2 was higher (38.3±8.4 vs. 26.8±6.1 years, p<0.001). Respiratory symptoms most frequently led to CF diagnosis in all patients, mainly in adulthood. There was a greater percentage of patients homozygous for the mutation delF508 in G1 (43.6 vs. 8.8%, p=0.02). Respiratory and pancreatic function, and body mass index (BMI) showed a higher severity in G1 (G1 vs. G2: FEV1: 54.6±27.3 vs. 29.9±64.6%, p=0.177; pancreatic insufficiency 72.7 vs. 26.5%, p<0.001; BMI 20.2±3.4 vs. 22.2±4.8, p=0.018). Pseudomonas aeruginosa and methicillin-sensitive Staphylococcus aureus were the most frequently isolated microorganisms. Lung transplantation rate was higher in G2 (20.6 vs. 10.9%, p=0.231) while mortality rate was higher in G1 (0 vs. 3.6%, p=0.261). Hospital admission rate was higher in G1 as well as mortality rate. The results suggest that patients with CF diagnosed in childhood have characteristics that distinguish them from those diagnosed in adulthood, and these differences may have implications for diagnosis, prognosis and life expectancy.

    Neck pain presents a tremendous physical and financial burden. This study compared the efficacy of the complementary and alternative medical treatments of integrative muscular movement technique (IMMT) and Swedish massage on neck pain in women of occupation age, the largest demographic group with neck pain. A total of 38 women were assigned to IMMT (n=28) or Swedish massage (n=10) in a blinded manner. Both groups received eight 30-minute treatments over 4 weeks. Cervical range of motion (ROM) in flexion, extension, sidebending, and rotation was measured before and after treatment. Each patient's pain was assessed by using an analogue pain scale of 0-10. Compared with the Swedish massage group, patients receiving IMMT experienced a significant increase in ROM in cervical flexion (ppain for IMMT was -1.75 units compared with -0.3 units for Swedish massage (pcervical ROM in every movement measured compared with Swedish massage. Inclusion of the IMMT in a treatment regimen for chronic neck pain may lead to decreased pain and increased cervical ROM. These positive effects of the IMMT intervention may have a role in enhancing functional outcomes in patients with neck pain.

    This study presents new zircon U-Pb ages and geochemical data for Neoproterozoic granitoids in the Songnen-Zhangguangcai Range Massif (SZRM) of NE China. This dataset provides insights into the Neoproterozoic tectonic setting of the SZRM and the links between this magmatism and the evolution of the Rodinia supercontinent. The zircon U-Pb dating indicates that the Neoproterozoic magmatism within the SZRM can be subdivided into two stages: (1) a ∼917-911 Ma suite of syenogranites and monzogranites, and (2) an ∼841 Ma suite of granodiorites. The 917-911 Ma granitoids contain high concentrations of SiO2 (67.89-71.18 wt.%), K2O (4.24-6.91 wt.%), and Al2O3 (14.89-16.14 wt.%), and low concentrations of TFe2O3 (1.63-3.70 wt.%) and MgO (0.53-0.88 wt.%). They are enriched in the light rare earth elements (LREE) and the large ion lithophile elements (LILE), are depleted in the heavy REE (HREE) and the high field strength elements (HFSE; e.g., Nb, Ta, and Ti), and have slightly positive Eu anomalies, indicating that they are geochemically similar to high-K adakitic rocks. They have zircon εHf (t) values and TDM2 ages from -4.4 to +1.5 and 1915 Ma to 1592 Ma, respectively, suggesting that they were derived from a primary magma generated by the partial melting of ancient thickened lower crustal material. In comparison, the 841 Ma granodiorites contain relatively low concentrations of Al2O3 (14.50-14.58 wt.%) and K2O (3.27-3.29 wt.%), relatively high concentrations of TFe2O3 (3.78-3.81 wt.%) and the HREE, have negative Eu anomalies, and have zircon εHf (t) values and TDM2 ages from -4.7 to +1.0 and 1875 to 1559 Ma, respectively. These granodiorites formed from a primary magma generated by the partial melting of ancient crustal material. The ∼917-911 Ma magmatism within the SZRM is inferred to have formed in an orogenic setting, whereas the ∼841 Ma magmatism formed in an anorogenic setting related to either a post-orogenic tectonic event or the onset of Neoproterozoic

    Full Text Available It is time to bring our imagination, creativity and passion to the fore in solving the global challenges of our age. Our global health crisis and the pandemic of noncommunicable diseases (NCDs is clearly rooted in complex modern societal and environmental changes, many of which have effects on developing immune and metabolic responses. It is intimately related to wider environmental challenges. And it is unsurprising that many NCDs share similar risk factors and that many are associated with a rising predisposition for inflammation. Allergy is one of the earliest signs of environmental impact on these biological pathways, and may also offer an early barometer to assess the effects of early interventions. There is dawning awareness of how changing microbial diversity, nutritional patterns, sedentary indoor behaviours and modern pollutants adversely affect early metabolic and immune development, but still much to understand the complexity of these interactions. Even when we do harness the science and technology, these will not provide solutions unless we also address the wider social, cultural and economic determinants of health - addressing the interconnections between human health and the health of our environment. Now more than ever, we need a wider vision and a greater sense of collective responsibility. We need long-range approaches that aim for life long benefits of a ‘healthier start to life’, and stronger cross-sectoral collaborations to prevent disease. We need to give both our hearts and our minds to solving these global issues.

    Iron (Fe) deficiency is the most common nutritional problem among children and lead (Pb) toxicity is the most common environmental health threat to children all over the world. The objective of this study was to determine blood lead (BPb) levels and prevalence of Fe deficient anemia among 1 to 5 year old children attending day care clinic in pediatric ward of civil hospital Karachi, Pakistan. A total of 340 children of both genders participating in this study, were screened for anemia. Among them 215 were anemic and 125 non-anemic. The anemic group was further divided in two groups on the basis of % hemoglobin (Hb), mild (Hb 10 g/dL). The blood samples were analysed for Pb and Fe, along with hematological parameters. The result indicated that anemic children had a higher mean values of Pb in blood than referent children with Hb > 10 g/dL. The Pb levels 10 μg/dL. The BPb concentration in severe anemic children (53%) was found in the range of 100-200 μg/L, whereas 47% had > 200 μg/L. The significant negative correlations of BPb level with % Hb (r = -0.514 and r = -0.685) and Fe contents (r = -0.522, r = -0.762, p < 0.001) were observed in mild and severe anemic children respectively. While positive correlation was observed between BPb and age of both group and genders (r = 0.69, p < 0.01). The BPb levels were significantly associated with biochemical indices in the blood which have the potential to be used as biomarkers of Pb intoxication and Fe deficient anemia.

The BPb concentration in severe anemic children (53%) was found in the range of 100-200 {mu}g/L, whereas 47% had > 200 {mu}g/L. The significant negative correlations of BPb level with % Hb (r = -0.514 and r = -0.685) and Fe contents (r = -0.522, r = -0.762, p < 0.001) were observed in mild and severe anemic children respectively. While positive correlation was observed between BPb and age of both group and genders (r = 0.69, p < 0.01). The BPb levels were significantly associated with biochemical indices in the blood which have the potential to be used as biomarkers of Pb intoxication and Fe deficient anemia.

Previous research has indicated that patient refusal of treatment is a contributing factor. This study aimed to identify potential barriers to adjuvant chemotherapy use in older patients by examining the associations between patient age, factors influencing chemotherapy treatment decisions, and preferences for information and decision-making involvement.Patients and methods: Sixty-eight patients who underwent surgery for colorectal cancer in Sydney, Australia, within the previous 24 months completed a self-administered survey.Results: Fear of dying, health status, age, quality of life, and understanding treatment procedures and effects were significantly more important to older patients (aged ≥65 years than younger patients in deciding whether to accept chemotherapy (all P < 0.05. Reducing the risk of cancer returning and physician trust were important factors for all patients. Practical barriers such as traveling for treatment and cost were rated lowest. Older patients preferred less information and involvement in treatment decision making than younger patients. However, 60% of the older group wanted detailed information about chemotherapy, and 83% wanted some involvement in decision making. Those preferring less information and involvement still rated many factors as important in their decision making, including understanding treatment procedures and effects.Conclusion: A range of factors appears to influence

    The purpose of this study was to explore the relationship between disability status and duration of morning stiffness in hands with regard to age, level of education, and gender in patients with rheumatoid arthritis (RA). Also, the authors wanted to investigate this relationship with regard to the presence of rheumatoid factor, i.e., the serological status. A retrospective study was conducted in 250 patients with the classic form of RA (186 females, s64 males, mean age Xb = 49.96 y ears, range 25-60 years, disease duration 1-27 years, Xb = 6.41) previously diagnosed with RA according to the ACR (American College of Rheumatology 1987 criteria). All patients were in Steinbrocker functional classes II and III. The probability level was expressed by p 0.05) seronegative, (r = 0.12, y = 0.00x + 2.30, p > 0.05) seropositive]. High positive values were obtained for the linear correlation coefficient between duration of the disease and functional class (p < 0.01). Also, high values were obtained regarding the coefficient of correlation between age and functional class [(r = 0.29, p < 0.01) seronegative, (r = 0.47, p < 0.01) seropositive]. Uneducated patients were significantly more represented in functional class III [ 23 (50%) seronegative, 19 (42.2%) seropositive] than in functional class II [16 (20.3%) seronegative, 22 (27.5%) seropositive]. In conclusion, in this study of patients with rheumatoid arthritis, increased duration of morning stiffness was associated with functional disability. Functional disability increased with the duration of the disease, depended on age and educational level, and was more pronounced in older age, regardless of RA serological status. With regard to serological status and sex, the differences were non-significant.

    Full Text Available Background/Aim: To explore the theory of ‘growing into deficits', a concept known from developmental neurology, in a series of cases with chronic hydrocephalus (CH. Methods: Patients were selected from the Amsterdam Dementia Cohort and underwent extensive dementia screening. Results: Twelve patients with CH were selected, in whom Alzheimer's disease was considered unlikely, based on biomarker information and follow-up. Mean Mini-Mental State Examination score was 24 (range 7-30. Most patients were functioning on a level of mild dementia [Clinical Dementia Rating score of 0.5 in 8/11 (66.7% patients]. On neuropsychological examination, memory and executive functions, as well as processing speed were most frequently impaired. Conclusion: In our opinion, the theory of ‘growing into deficits' shows a parallel with the clinical course of CH and normal aging when Alzheimer's disease was considered very unlikely, because most of these patients were functioning well for a very large part of their lives. The altered cerebrospinal fluid dynamics might make the brain more vulnerable to aging-related changes, leading to a faster cognitive decline in CH patients compared to healthy subjects, especially in case of concomitant brain damage such as traumatic brain injury or meningitis.

    Full text: The aim was to analyze the influence of the age of the patient and tumor size on the accuracy to identify SN in patients with breast cancer. The whole population are 250 patients with breast cancer. In 236 data on size and age were available. Mean age was 53.6 years, range 28-87 years. Patients were classified 1) depending an age: 40 60 years: 73 p and 2) depending on tumor size (mm): 30: 46 p. Examination protocol: All patients received a peritumoral injection of 111 MBq (3mCi) of 99mTc-HSA-nanocolloid in 1 - 3 ml. 2 h later 300 seconds anterior and lateral thoracic scans were obtained. A 57-Co flood phantom was positioned back to the patient to outline the anatomical contour and help to localize SN. SN was marked on the skin with permanent ink. Intraoperative SN localization was performed using a gamma probe. Histopathologic analysis of SN was done with haematoxylin/eosin, immunohistochemistry and PCR. Histopathology of the SN was compared to the histopathology of all the other lymph nodes drawn out by the surgeon. SN were identified by lymphoscintigraphy in 227 cases of 250 (91 %). 221 of them (97 %) were localized in axyla. In 210 of 221 SN could be localized and drawn out at surgery. The no detection and false negative rate were much higher in patients aged > 60 (29 and 33 %) and in tumors > 30 mm (32 and 19 %) than in patients 60 y and tumors > 30 mm (46 %) and the highest false negative rate appears in patients >60 and tumors > 30 mm (33 %) 1) No FN were found in patients with tumor size <10 mm. 2) No FN were found in patients aged under 40 years. 3) FN rate seems to be higher in older patients. 4) The age of patients and the size of tumor seem to influence an the SN detection rates.

    Full Text Available Hirschsprung’s disease is a congenital motility disorder that is easily overlooked as a cause of chronic refractory constipation in adults. We present a case of Hirschsprung’s disease in a patient 70 years of age with a history of long-standing constipation, chronic use of laxatives, and recurrent episodes of colonic obstruction. Presumptive preoperative diagnosis was chronic ischemic sigmoid stenosis or intermittent sigmoid volvulus before Hirschsprung’s disease was suspected based on intraoperative colonoscopy and surgical findings. The diagnosis was confirmed by the absence of intrinsic ganglion cells on histopathologic examination of the surgical specimen and the absence of the rectoanal inhibitory reflex on postoperative manometry. A conservative surgical approach that limited the resection to the grossly diseased rectum successfully restored normal defecation despite the anastomosis being performed on the distal aganglionic rectum. This approach, which avoids extensive rectal dissection, may be suitable for older or frail patients. Heightened awareness of Hirschsprung’s disease is necessary to ensure its prompt recognition in the elderly.

    The Xinlin-Xiguitu suture zone, located in the Great Xing'an Range, NE China, in the eastern segment of the Central Asian Orogenic Belt (CAOB), represents the boundary between the Erguna and Xing'an micro-continental blocks. The exact location of the Xinlin-Xiguitu suture zone has been debated, especially, the location of the northern extension of the suture zone. In this study, based on a detailed field, geochemical, geochronological and Sr-Nd-Hf isotope study, we focus our work on the Cambrian igneous rocks in the Erguna-Xing'an block. The Xinglong granitoids, mainly include ∼520 Ma diorite, ∼470 Ma monzogranite and ∼480 Ma pyroxene diorite. The granitoids show medium to high-K calc-alkaline series characteristics with post-collision granite affinity. The circa 500 Ma granitoids have low εHf (t) values (-16.6 to +2.2) and ancient two-stage model (TDM2) ages between 1317 Ma and 2528 Ma. These results indicate the primary magmas of the Xinglong granitoids were probably derived from the partial melting of a dominantly Paleo-Mesoproterozoic ;old; crustal source with possible different degrees of addition of juvenile materials, and formed in a post-collision tectonic setting after the amalgamation of the Erguna and Xing'an blocks. Compared with the Xinglong granitoids, the Duobaoshan igneous rocks are consisted of the approximately coeval rhyolitic tuffs (491 ± 5 Ma) and ultramafic intrusions (497 ± 5 Ma) within the Duobaoshan Formation. They are generally enriched in large ion lithophile elements (LILEs) and depleted in high field strength elements (HFSEs; e.g., Nb, Ta, and Ti), consistent with the geochemistry of igneous rocks from island arcs or active continental margins. The ultramafic rocks have high positive εHf (t) values (+1.3 to +15) and εNd (t) (+1.86 to +2.28), and relatively young two-stage model (TDM2) ages and low initial 87Sr/86Sr ratios (0.70628-0.70853), indicating the partial melting of a depleted mantle source from a subducted slab in

    Introduction An increasing proportion of the population is living into their nineties and beyond. These high risk patients are now presenting more frequently to both elective and emergency surgical services. There is limited research looking at outcomes of general surgical procedures in nonagenarians and centenarians to guide surgeons assessing these cases. Methods A retrospective analysis was conducted of all patients aged ≥90 years undergoing elective and emergency general surgical procedures at a tertiary care facility between 2009 and 2015. Vascular, breast and endocrine procedures were excluded. Patient demographics and characteristics were collated. Primary outcomes were 30-day and 90-day mortality rates. The impact of ASA (American Society of Anesthesiologists) grade, operation severity and emergency presentation was assessed using multivariate analysis. Results Overall, 161 patients (58 elective, 103 emergency) were identified for inclusion in the study. The mean patient age was 92.8 years (range: 90-106 years). The 90-day mortality rates were 5.2% and 19.4% for elective and emergency procedures respectively (p=0.013). The median survival was 29 and 19 months respectively (p=0.001). Emergency and major gastrointestinal operations were associated with a significant increase in mortality. Patients undergoing emergency major colonic or upper gastrointestinal surgery had a 90-day mortality rate of 53.8%. Conclusions The risk for patients aged over 90 years having an elective procedure differs significantly in the short term from those having emergency surgery. In selected cases, elective surgery carries an acceptable mortality risk. Emergency surgery is associated with a significantly increased risk of death, particularly after major gastrointestinal resections.

    To estimate the incidence of disc displacement, disc deformity, and bone changes of the temporomandibular joint in elderly patients with temporomandibular disorders, 55 elderly patients (110 joints) were examined by magnetic resonance imaging. The ages of the patients ranged from 65 to 89 years (average, 70 years). They consisted of 13 men and 42 women. Normal disc position was found in 40 joints (36.4%), anterior disc displacement with reduction in 17 joints (15.5%), and anterior disc displacement without reduction in 53 joints (48.2%) on magnetic resonance imaging. Thirty-eight (71.6%) of the 53 joints with anterior disc displacement without reduction had disc deformity and 33 (62.3%) had bone changes. The frequency of bone changes in the elderly group was higher than that in the younger group. Women had a higher incidence of bone changes than men. (author)

    The aim of this study was to investigate the prevalence of risk of malnutrition (RoM) in an orthopedic and traumatology patient cohort with a broad range of ages. In addition to the classical indicators for risk assessment (low body mass index, weight loss, and comorbidity), this study aimed to analyze the effects of lifestyle factors (eating pattern, smoking, physical activity) on RoM. The prospective cohort study included 1053 patients in a level 1 trauma center in Germany. RoM was assessed by Nutritional Risk Screening (NRS) 2002 and for the elderly additionally by Mini Nutritional Assessment (MNA). Age-dependent risk factors identified in univariate statistical analysis were used for multivariate logistic regression models. The prevalence of patients at RoM (NRS ≥3) was 22%. In the three age categories (<50 y, 50-69 y, and ≥70 y), loss of appetite, weight loss, number of comorbidities, drugs and gastrointestinal symptoms significantly increased RoM in univariate statistical analysis. In patients ages ≥70 y, several disease- and lifestyle-related factors (not living at home, less frequent consumption of vegetables and whole meal bread, low physical activity, and smoking) were associated with RoM. Multivariate logistic regression model for the total study population identified weight loss (odds ratio [OR], 6.09; 95% confidence interval [CI], 4.14-8.83), loss of appetite (OR, 3.81; 95% CI, 2.52-5.78), age-specific low BMI (OR, 1.87; 95% CI, 1.18-2.97), number of drugs taken (OR, 1.19; 95% CI, 1.12-1.26), age (OR, 1.03; 95% CI, 1.02-1.04), and days per week with vegetable consumption (OR, 0.938; 95% CI, 0.89-0.99) as risk factors. Malnutrition in trauma and orthopedic patients is not only a problem related to age. Lifestyle-related factors also contribute significantly to malnutrition in geriatric patients.

    Purpose: To present 23 patients ≥ 90 years old treated with radiotherapy, and to retrospectively evaluate the results of radiotherapy and tolerance in these patients. Methods and Materials: The clinical records of 27 patients over 90 years of age who were treated with radiotherapy at the Department of Radiology, Shinshu University Hospital, and eight affiliated general hospitals from 1990 until 1995 were reviewed. The strategy of radiotherapy was individually planned depending on the stage of the disease and performance status (PS) of the patient; however, it was not modified, based solely on chronologic age. The overall survival rate and disease-free survival rate were determined using the Kaplan-Meier method. The Radiation Therapy Oncology Group scoring criteria of acute and late reactions of radiation therapy were used. Results: This group of patients accounted for 0.37% of all patients treated with radiotherapy in these hospitals. Of these, 23 patients in whom cancer was pathologically confirmed and whose follow-up data were available for retrospective analysis were included in the final evaluation of data. The age of the 23 patients ranged from 90 to 96 years (median 93). Tumor was untreated and in the early stage in five patients, locoregionally advanced in 13, recurrent in four, and systemic in one. Definitive radiation therapy was administered in 12 patients (13 sites), preoperative intent in one, and palliative intent in 10. The period of observation ranged from 2.5 to 6 years (median 18 months). Seven patients were alive for 15-67 months. Fourteen patients died because of intercurrent diseases or senility associated with active cancer, and two because of senility without evidence of cancer. The overall and relapse-free survival rates were 65% and 30% at 1 year and 30% and 21% at 2 years, respectively. Definitive radiation therapy was completed in 13 of 13 patients (100%), and local control was attained in 9 of 13 patients at 6 months (62%). Palliative

    This study aimed at determining the efficacy of the surgical treatment conducted on children with delayed presentation developmental dysplasia of the hip (DDH). The objective was to provide a good comparison of functional and radiographic outcomes and to determine various surgical treatment options. In this study, we evaluated the results of 38 hips of 27 patients aged 4 years onset which had been operated due to DDH. Radiographic outcomes were evaluated by using acetabular index, CE angle, Tonnis and the Severin classification system. Clinical evaluation was made by using IOWA hip scores. Degenerative changes were evaluated according to Boyer and avascular necrosis according to Kalamchi-MacEwen criteria. The mean age of the patients at the operation time was 10 years 3 months (range: 4 years 3 months-30 years). While the mean acetabular index was 37.97 preoperatively, in the last follow-up it was 19.92. Thirty-six hips (94%) had an excellent and good outcomes, and two hips (%6) had a fair outcome with respect to the Severin criteria. The mean hip score with respect to IOWA was 93.736 (range: 75-98) and the rate of excellent and good outcomes was 98%. For the treatment of patients with DDH of late onset, a one-staged operative procedure is recommended. This method is applied successfully and enables us to achieve good clinical and radiographic results. Copyright © 2018 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

    The age at exposure significantly affects the retention and distribution of 226 Ra and 239 Pu, both of which deposit in the skeleton, although in different patterns. Beagles aged 2 days (neonates), 90 days (juveniles), 18 months (young adults) or 5 years (old), received a single injection of one of these nuclides at a dosage level at which no significant acute effects have been observed. Nuclide concentrations in plasma and the skeleton were determined and retention equations were calculated. Initial deposition and retention of the two nuclides were age-dependent, but differences between the growing and young adult beagles were much greater than between the young adult and old beagles

    Purpose: To determine the rate of treatment deviations during combined modality therapy for rectal cancer in elderly patients aged 75 years and older. Methods and Materials: We reviewed the records of consecutively treated patients with rectal cancer aged 75 years and older treated with combined modality therapy at Massachusetts General Hospital and Brigham and Women’s Hospital from 2002 to 2007. The primary endpoint was the rate of treatment deviation, defined as a treatment break, dose reduction, early discontinuation of therapy, or hospitalization during combined modality therapy. Patient comorbidity was rated using the validated Adult Comorbidity Evaluation 27 Test (ACE-27) comorbidity index. Fisher’s exact test and the Mantel–Haenszel trend test were used to identify predictors of treatment tolerability. Results: Thirty-six eligible patients had a median age of 79.0 years (range, 75–87 years); 53% (19/36) had no or mild comorbidity and 47% (17/36) had moderate or severe comorbidity. In all, 58% of patients (21/36) were treated with preoperative chemoradiotherapy (CRT) and 33% (12/36) with postoperative CRT. Although 92% patients (33/36) completed the planned radiotherapy (RT) dose, 25% (9/36) required an RT-treatment break, 11% (4/36) were hospitalized, and 33% (12/36) had a dose reduction, break, or discontinuation of concurrent chemotherapy. In all, 39% of patients (14/36) completed ≥4 months of adjuvant chemotherapy, and 17% (6/36) completed therapy without a treatment deviation. More patients with no to mild comorbidity completed treatment than did patients with moderate to severe comorbidity (21% vs. 12%, p = 0.66). The rate of deviation did not differ between patients who had preoperative or postoperative CRT (19% vs. 17%, p = 1.0). Conclusions: The majority of elderly patients with rectal cancer in this series required early termination of treatment, treatment interruptions, or dose reductions. These data suggest that further intensification

    Animal vocal signals are increasingly used to monitor wildlife populations and to obtain estimates of species occurrence and abundance. In the future, acoustic monitoring should function not only to detect animals, but also to extract detailed information about populations by discriminating sexes, age groups, social or kin groups, and potentially individuals. Here we show that it is possible to estimate age groups of African elephants (Loxodonta africana) based on acoustic parameters extracte...

    Full Text Available Abstract Background To examine the role of brachytherapy for aged patients 80 or more in the trend of rapidly increasing number. Methods We examined the outcomes for elderly patients with node negative oral tongue cancer (T1-3N0M0 treated with brachytherapy. The 21 patients (2 T1, 14 T2, and 5 T3 cases ranged in age from 80 to 89 years (median 81, and their cancer was pathologically confirmed. All patients underwent definitive radiation therapy, with low dose rate (LDR Ra-226 brachytherapy (n = 4; median 70Gy, with Ir-192 (n = 12; 70Gy, with Au-198 (n = 1 or with high dose rate (HDR Ir-192 brachytherapy (n = 4; 60 Gy. Eight patients also underwent external radiotherapy (median 30 Gy. The period of observation ranged from 13 months to 14 years (median 2.5 years. We selected 226 population matched younger counterpart from our medical chart. Results Definitive radiation therapy was completed for all 21 patients (100%, and acute grade 2-3 mucositis related to the therapy was tolerable. Local control (initial complete response was attained in 19 of 21 patients (90%. The 2-year and 5-year local control rates were 91%, (100% for T1, 83% for T2 and 80% for T3 tumors after 2 years. These figures was not inferior to that of younger counterpart (82% at 5-year, n.s.. The cause-specific survival rate was 83% and the regional control rate 84% at the 2-years follow-up. However, 12 patients died because of intercurrent diseases or senility, resulting in overall survival rates of 55% at 2 years and 34% at 5 years. Conclusion Age is not a limiting factor for brachytherapy for appropriately selected elderly patients, and brachytherapy achieved good local control with acceptable morbidity.

    The increasing use of anti-Müllerian hormone (AMH) in clinic has raised concerns regarding the reliable reference range for this test. However, the reference range for AMH in normal Chinese female population has not been established. Furthermore, relationship between AMH and other clinical markers such as body mass index (BMI) and antral follicle counts (AFCs) and other sex-related hormones have not been examined in normal population-based women. We aimed to determine the age-specific reference range for serum AMH in healthy Chinese women throughout reproductive age to menopause and to estimate relationship between AMH and other clinical markers in healthy women. In this multicenter and nationwide study, advertisements were used to recruit 2055 women, aged 20 to 55 years, from 6 different regions in China; 1590 (77.37%) women met the inclusion criteria for the reference range population. We measured the baseline serum AMH levels using new Beckman Coulter Gen II assay. Serum concentration of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), prolactin (PRL), progesterone (PRG), and AFCs were also determined in the follicular phase. The AMH-Age nomogram and AMH levels of different age-groups and the relationship between AMH and other clinical markers. Serum AMH concentrations declined progressively with age. A quadratic model defined as log (AMH) = (-1.970 + 0.296 × Age - 0.006 × Age(2)) fitted best the decline of AMH with age. The median AMH levels were 6.23, 5.65, 4.55, 3.74, 2.78, and 1.09 ng/mL for the 20 ≤ age women. © The Author(s) 2016.

    Full Text Available Range of motion (ROM measurements are essential for the evaluation for and diagnosis of adhesive capsulitis of the shoulder (AC. However, taking these measurements using a goniometer is inconvenient and sometimes unreliable. The Kinect (Microsoft, Seattle, WA, USA is gaining attention as a new motion detecting device that is nonintrusive and easy to implement. This study aimed to apply Kinect to measure shoulder ROM in AC; we evaluated its validity by calculating the agreement of the measurements obtained using Kinect with those obtained using goniometer and assessed its utility for the diagnosis of AC. Both shoulders of 15 healthy volunteers and affected shoulders of 12 patients with AC were included in the study. The passive and active ROM of each were measured with a goniometer for flexion, abduction, and external rotation. Their active shoulder motions for each direction were again captured using Kinect and the ROM values were calculated. The agreement between the two measurements was tested with the intraclass correlation coefficient (ICC. Diagnostic performance using the Kinect ROM was evaluated with Cohen's kappa value. The cutoff values of the limited ROM were determined in the following ways: the same as passive ROM values, reflecting the mean difference, and based on receiver operating characteristic curves. The ICC for flexion/abduction/external rotation between goniometric passive ROM and the Kinect ROM were 0.906/0.942/0.911, while those between active ROMs and the Kinect ROMs were 0.864/0.932/0.925. Cohen's kappa values were 0.88, 0.88, and 1.0 with the cutoff values in the order above. Measurements of the shoulder ROM using Kinect show excellent agreement with those taken using a goniometer. These results indicate that the Kinect can be used to measure shoulder ROM and to diagnose AC as an alternative to goniometer.

    To evaluate the efficacy and the rate of side effects of the pegylated aptamer pegaptanib in the treatment of patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) and a history of previous arterial thromboembolic events (ATEs). Twenty-three eyes of 23 patients with subfoveal CNV due to AMD and cerebrovascular accidents (n = 12) and myocardial infarction (n = 11) in the previous 6 months received intravitreal pegaptanib 0.3 mg according to a pro re nata regimen and were followed for 12 months. The paired Student t test was used to evaluate mean changes in best-corrected visual acuity (BCVA; primary outcome measure) and central foveal thickness (CFT). The mean patient age was 71.5 ± 4.6 years; there were 14 women and 9 men. The CNV was type 1, 2, and 3 in 18, 3, and 2 eyes, respectively. The mean BCVA improved from 0.67 ± 0.23 logMAR at baseline to 0.52 ± 0.31 logMAR at the end of 12-month follow-up (p = 0.044). Thirty-five percent of patients achieved ≥3 Early Treatment Diabetic Retinopathy Study lines improvement at 12 months. Mean CFT at baseline (381 ± 111 µm) decreased to 304 ± 82 µm at 12 months (p = 0.008). Patients received a mean of 4.3 ± 1.3 (range 3-7) injections. No systemic or ocular side effects occurred; no patient experienced further ATEs. Intravitreal pegaptanib can be considered a viable treatment option for patients with AMD-related CNV who are at high risk of ATEs.

    Highlights: • MDCT imaging of the aortoventricular interface is increasingly common. • We present normative ranges for aortoventricular interface dimensions. • Such techniques and ranges should be used to standardise reporting and research. - Abstract: Background: Multidetector computed tomographic (MDCT) assessment of the aortoventricular interface has gained increased importance with the advent of minimally invasive treatment modalities for aortic and mitral valve disease. This has included a standardised technique of identifying a plane through the nadir of each coronary cusp, the basal plane, and taking further measurements in relation to this plane. Despite this there is no published data defining normal ranges for these aortoventricular metrics in a healthy cohort. This study seeks to quantify normative ranges for MDCT derived aortoventricular dimensions and evaluate baseline demographic and anthropomorphic associates of these measurements in a normal cohort. Methods: 250 consecutive patients undergoing MDCT coronary angiography were included. Aortoventricular dimensions at multiple levels of the aortoventricular interface were assessed and normative ranges quantified. Multivariate linear regression was performed to identify baseline predictors of each metric. Results: The mean age was 59 ± 12 years. The basal plane was eccentric (EI = 0.22 ± 0.06) while the left ventricular outflow tract was more eccentric (EI = 0.32 ±0.06), with no correlation to gender, age or hypertension. Male gender, height and body mass index were consistent independent predictors of larger aortoventricular dimensions at all anatomical levels, while age was predictive of supra-annular measurements. Conclusions: Male gender, height and BMI are independent predictors of all aortoventricular dimensions while age predicts only supra-annular dimensions. Use of defined metrics such as the basal plane and formation of normative ranges for these metrics allows reference for clinical

    Study Objectives: Narcolepsy is reported to affect 26-56/100,000 in the general population. We aimed to describe clinical and polysomnographic features of a large narcolepsy cohort in order to comprehensively characterize the narcoleptic spectrum. Methods: We performed a chart- and polysomnographybased review of all narcolepsy patients of the Innsbruck narcolepsy cohort. Results: A total of 100 consecutive narcolepsy patients (87 with cataplexy [NC], 13 without cataplexy [N]) were included in the analysis. All subjects had either excessive daytime sleepiness or cataplexy as their initial presenting clinical feature. Age at symptom onset was 20 (6-69) years. Diagnostic delay was 6.5 (0-39) years. The complete narcolepsy tetrad was present in 36/100 patients; 28/100 patients had three cardinal symptoms; 29/100 had two; and 7/100 had only excessive daytime sleepiness. Severity varied broadly with respect to excessive daytime sleepiness (median Epworth Sleepiness Scale score: 18, range 10-24), cataplexy (8-point Likert scale: median 4.5, range 1-8), hypnagogic hallucinations (median 4.5, range 1-7), and sleep paralysis (median 3, range 1-7). Sleep comorbidity was highly prevalent and ranged from sleeprelated movement disorders (n = 55/100), parasomnias (n = 34/100), and sleeprelated breathing disorders (n = 24/100), to insomnia (n = 28/100). REM sleep without atonia or a periodic limb movement in sleep index > 5/h were present in most patients (90/100 and 75/100). A high percentage of narcoleptic patients in the present study had high frequency leg movements (35%) and excessive fragmentary myoclonus (22%). Of the narcolepsy patients with clinical features of REM sleep behavior disorder (RBD), 76.5% had EMG evidence for RBD on the multiple sleep latency test (MSLT), based on a standard cutoff of a minimum of 18% of 3-sec miniepochs. Conclusion: This study is one of the largest monocentric polysomnographic studies to date of patients with narcolepsy and confirms the

    BACKGROUND/STUDY CONTEXT: Chronic pain is associated with increased interference in daily functioning that becomes more pronounced as pain intensity increases. Based on previous research showing that older adults maintain well-being in the face of pain as well as or better than their younger counterparts, the current study examined the interaction of age and pain intensity on interference in a sample of chronic orofacial pain patients. Data were obtained from the records of 508 chronic orofacial pain patients being seen for an initial evaluation from 2008 to 2012. Collected data included age (range: 18-78) and self-reported measures of pain intensity and pain interference. Bivariate correlations and regression models were used to assess for statistical interactions. Regression analyses revealed that pain intensity positively predicted pain interference (R(2) = .35, B = 10.40, SE = 0.62, t(507) = 16.70, p theories, including socioemotional selectivity theory, which posits that as people age, they become more motivated to maximize positive emotions and minimize negative ones. The results highlight the importance of studying the mechanisms older adults use to successfully cope with pain.

    Although efficacious in stroke prevention in non-valvular atrial fibrillation, many warfarin patients are sub-optimally managed. To evaluate the association of international normalized ratio control and clinical outcomes among new warfarin patients with non-valvular atrial fibrillation. Adult non-valvular atrial fibrillation patients (≥18 years) initiating warfarin treatment were selected from the US Veterans Health Administration dataset between 10/2007 and 9/2012. Valid international normalized ratio values were examined from the warfarin initiation date through the earlier of the first clinical outcome, end of warfarin exposure or death. Each patient contributed multiple in-range and out-of-range time periods. The relative risk ratios of clinical outcomes associated with international normalized ratio control were estimated. 34,346 patients were included for analysis. During the warfarin exposure period, the incidence of events per 100 person-years was highest when patients had international normalized ratio 3, patients had significantly increased risk of major bleeding (relative risk ratio: 1.5; 95 % confidence interval 1.2-2.0). In a Veterans Health Administration non-valvular atrial fibrillation population, exposure to out-of-range international normalized ratio values was associated with significantly increased risk of adverse clinical outcomes.

    Little is known about the relationship between implant patient mortality compared to reference populations. The aim of this study was to report the mortality pattern in patients treated with dental implants up to a 15-year period, and to compare this to mortality in reference populations with regard to age at surgery, sex, and degree of tooth loss. Patient cumulative survival rate (CSR) was calculated for a total of 4,231 treated implant patients from a single clinic. Information was based on surgical registers in the clinic and the National Population Register in Sweden. Patients were arranged into age groups of 10 years, and CSR was compared to that of the reference population of comparable age and reported in relation to age at surgery, sex, and type of jaw/dentition. A similar, consistent, general relationship between CSR of different age groups of implant patients and reference populations could be observed for all parameters studied. Completely edentulous patients presented higher mortality than partially edentulous patients (P age groups showed mortality similar to or higher than reference populations, while older patient age groups showed increasingly lower mortality than comparable reference populations for edentulous and partially edentulous patients (P age groups of patients compared to reference populations was observed, indicating higher patient mortality in younger age groups and lower in older groups. The reported pattern is not assumed to be related to implant treatment per se, but is assumed to reflect the variation in general health of a selected subgroup of treated implant patients compared to the reference population in different age groups.

    Recent studies have shown a discrepancy between traditional functional outcomes and patient satisfaction, with some reporting less than 85% satisfaction in older patients undergoing total knee arthroplasty (TKA). As native knee biomechanics are not completely replicated, the resulting functional limitations may cause dissatisfaction in higher-demand individuals. Few studies have recorded patient-reported outcomes, health-related quality of life scores, and patient satisfaction in a young population undergoing TKA. One hundred thirty-six primary TKAs were performed in 114 patients aged 50 years or younger (mean age, 47.0 years; range, 30-50 years) at a single institution. The main diagnoses were osteoarthritis (85%) and rheumatoid arthritis (10%). The range of motion, Knee Society Score, Oxford Knee Score, and Physical and Mental Component Scores of Short Form-36 increased significantly (P patients had good/excellent knee scores, 71.3% had good/excellent function scores, 94.9% met the minimal clinically important difference for the Oxford Knee Score, and 84.6% met the minimal clinically important difference for the Physical Component Score. We found that 88.8% of patients were satisfied with their surgeries, whereas 86.8% had their expectations fulfilled. Survivorship using revision as an end point was 97.8% at a mean of 7 years (range, 3-16 years). Patients aged 50 years or younger undergoing TKA can experience significant improvements in their quality of life, have their expectations met, and be satisfied with their surgeries, at rates similar to those of non-age-restricted populations. Surgeons should inform them of these benefits and the potential risk of revision surgery in the future, albeit increasingly shown to be low. Copyright © 2016 Elsevier Inc. All rights reserved.

    To describe how vestibular rehabilitation influences pain and range of motion among patients with whiplash-associated disorder and dizziness, and to describe whether pain or range of motion correlated with balance performance or self-perceived dizziness handicap. A total of 29 patients, 20 women and 9 men, age range 22-76 years. Patients with whiplash-associated disorder and dizziness were randomized to either intervention (vestibular rehabilitation) or control. Neck pain intensity, cervical range of motion (CROM), balance and self-perceived dizziness handicap were measured at baseline, 6 weeks and 3 months. There were no differences in neck pain intensity or CROM between the 2 groups either at baseline, 6 weeks or 3 months (p = 0.10-0.89). At baseline, neck pain intensity correlated with CROM (-0.406) and self-perceived dizziness handicap (0.492). CROM correlated with self-perceived dizziness handicap and with 1 balance measure (-0.432). Neck pain intensity did not correlate with balance performance (-0.188-0.049). Neck pain intensity and CROM was not influenced by vestibular rehabilitation. Importantly, the programme did not appear to increase pain or decrease neck motion, as initially thought. Neck pain intensity and CROM correlated with self-perceived dizziness handicap. CROM also correlated with 1 balance measure.

The aim of this study is to define risk factors for deep venous thrombosis among patients younger than 50 years of age, to compare them with a control group, and to suggest recommendations for the management and treatment of venous thrombosis in this particular group of patients.Methods: From January 2003 to January 2011, 66 consecutive Lebanese patients (29 males and 37 females younger than 50 years, diagnosed in an academic tertiary-care center with lower extremity deep venous thrombosis by color flow duplex scan, were retrospectively reviewed. Their age varied between 21 and 50 years (mean 38.7 years. The control group included 217 patients (86 males and 131 females older than 50 years (range: 50–96 years; mean 72.9 years.Results: The most commonly reported risk factors in the younger age group were inherited thrombophilia (46.9% compared with 13.8% in the control group; P < 0.001, pregnancy (18.2% compared with 0.5%; P < 0.001, treatment with estrogen drugs (13.6% compared with 2.3%; P = 0.001, and family history of venous thromboembolism (9.1% compared with 3.8%; P = 0.084.Conclusion: Inherited thrombophilia is the most commonly observed risk factor among patients younger than 50 years, with a prevalence of three times more than the control group. Young adults should be screened for thrombophilia even in the presence of transient acquired risk factors.

    The aim of study was to examine echocardiographic indices of right heart chambers in patients with coronary artery disease in different age groups. On 678 patients aged 38-85 years, who underwent echocardiography, are including with the use of spectral tissue Doppler. Obtained 2 age groups: 1st - patients up to 60 years (n=282) and group 2nd - patients 60 years and older (n=396). In the analysis the obtained results in patients with coronary heart disease in older age groups showed an increase in right ventricular wall thickness, systolic and average pressure in the pulmonary artery. These changes were accompanied by deterioration in left ventricular diastolic function, while the systolic function of the left and right ventricle were independent of age. Thus, the results can be recommended for assessment of right ventricular dysfunction in patients of older age groups.

    Doctor-patient communication is a key driver of overall satisfaction with primary care. Patients from minority ethnic backgrounds consistently report more negative experiences of doctor-patient communication. However, it is currently unknown whether these ethnic differences are concentrated in one gender or in particular age groups. To determine how reported GP-patient communication varies between patients from different ethnic groups, stratified by age and gender. Analysis of data from the English GP Patient Survey from 2012-2013 and 2013-2014, including 1,599,801 responders. A composite score was created for doctor-patient communication from five survey items concerned with interpersonal aspects of care. Mixed-effect linear regression models were used to estimate age- and gender-specific differences between white British patients and patients of the same age and gender from each other ethnic group. There was strong evidence (Pcommunication varied by both age and gender. The difference in scores between white British and other responders on doctor-patient communication items was largest for older, female Pakistani and Bangladeshi responders, and for younger responders who described their ethnicity as 'Any other white'. The identification of groups with particularly marked differences in experience of GP-patient communication--older, female, Asian patients and younger 'Any other white' patients--underlines the need for a renewed focus on quality of care for these groups. © British Journal of General Practice 2016.

    Free-ranging African elephants live in a fission-fusion society, at the centre of which is the matriarch. Matriarchs are generally older females that guide their families to resources and co-ordinate group defense. While much is known about elephant society, knowledge is generally lacking about how age affects the physiology of wild elephants. Investigation of the ovarian activity of free-ranging elephants could provide insight into the reproductive ageing process, with implications for population management. Faecal samples were collected from 46 individuals ranging in age from 14 to 60 years for a 2-year period, and progestagen metabolite analyses were used to examine relationships between social status, age, season, and ovarian activity in female elephants in Addo Elephant National Park, South Africa. Social status was the strongest predictor of faecal progestagen metabolite concentrations in non-pregnant elephants, with grand matriarchs (n = 6) having the lowest values compared with matriarchs (n = 21) and non-matriarch females (n = 19). Likewise, social status and age were the strongest predictors of faecal progestagen metabolite concentrations in pregnant elephants (n = 27). The number of years since a non-pregnant female gave birth to her last calf (post-partum duration) was longer for older females with a higher social status, as well as during the dry season. Our results indicate that social standing and age of elephants are related to reproductive function, and that older females exhibit reductions in ovarian capacity. These results expand our understanding of reproduction and fertility throughout an elephant's lifespan, and the factors that impact gonadal function in free-ranging females. Given that possible over-abundance of elephants in areas such as Addo Elephant National Park is fuelling the debate over how best to manage these populations, knowledge about the reproductive potential of high-ranking females can provide managers with

    To provide normative values for cervical range of motion (CROM), isometric cervical and shoulder strength for; International Senior professional, and International Age-grade Rugby Union front-row forwards. Cross-sectional population study. All international level front-row players within a Rugby Union Tier 1 Nation. Nineteen Senior and 21 Age-grade front-row forwards underwent CROM, cervical and shoulder strength testing. CROM was measured using the CROM device and the Gatherer System was used to measure multi-directional isometric cervical and shoulder strength. The Age-grade players had significantly lower; cervical strength (26-57% deficits), cervical flexion to extension strength ratios (0.5 vs. 0.6), and shoulder strength (2-36% deficits) than the Senior players. However, there were no differences between front-row positions within each age group. Additionally, there were no differences between age groups or front-row positions in the CROM measurements. Senior Rugby Union front-row forwards have greater cervical and shoulder strength than Age-grade players, with the biggest differences being in cervical strength, highlighting the need for age specific normative values. Importantly, Age-grade players should be evaluated to ensure they have developed sufficient cervical strength prior to entering professional level Rugby Union. Copyright © 2015 Elsevier Ltd.

    The transport of biomass burning (BB) aerosol from Indochina may cause a potential effect on climate change in Southeast Asia, East Asia, and the Western Pacific. Up to now, the understanding of BB aerosol composition modification during long-range transport (LRT) is still very limited due to the lack of observational data. In this study, atmospheric aerosols were collected at the Suthep/Doi Ang Khang (DAK) mountain sites in Chiang Mai, Thailand and the Lulin Atmospheric Background Station (Mt. Lulin) in central Taiwan from March to April 2010 and from February to April 2013, respectively. During the study period, an upwind and downwind relationship between the Suthep/DAK and Lulin sites (2400 km apart) was validated by backward trajectories. Comprehensive aerosol properties were resolved for PM2.5 water-soluble inorganic ions, carbonaceous content, water-soluble/insoluble organic carbon (WSOC/WIOC), dicarboxylic acids and their salts (DCAS), and anhydrosugars. A Modification Factor (MF) is proposed by employing non-sea-salt potassium ion (nss-K+) or fractionalized elemental carbon evolved at 580 °C after pyrolized OC correction (EC1-OP) as a BB aerosol tracer to evaluate the mass fraction changes of aerosol components from source to receptor regions during LRT. The MF values of nss-SO42-, NH4+, NO3-, OC1 (fractionalized organic carbon evolved from room temperature to 140 °C), OP (pyrolized OC fraction), DCAS, and WSOC were above unity, which indicated that these aerosol components were enhanced during LRT as compared with those in the near-source region. In contrast, the MF values of anhydrosugars ranged from 0.1 to 0.3, indicating anhydrosugars have degraded during LRT.

    Purpose: Proton radiotherapy allows radiation treatment delivery with high dose gradients. The nature of such dose distributions increases the influence of patient positioning uncertainties on their fidelity when compared to photon radiotherapy. The present work quantitatively analyzes the influence of setup uncertainties on proton range and dose distributions. Methods: 38 clinical passive scattering treatment fields for small lesions in the head were studied. Dose distributions for shifted and rotated patient positions were Monte Carlo-simulated. Proton range uncertainties at the 50% and 90%-dose falloff position were calculated considering 18 arbitrary combinations of maximal patient position shifts and rotations for two patient positioning methods. Normal tissue complication probabilities (NTCPs), equivalent uniform doses (EUDs) and tumor control probabilities (TCPs) were studied for organs at risk (OARs) and target volumes of eight patients. Results: We identified a median 1σ proton range uncertainty at the 50%-dose falloff of 2.8 mm for anatomy-based patient positioning and 1.6 mm for fiducial-based patient positioning as well as 7.2 mm and 5.8 mm for the 90%-dose falloff position respectively. These range uncertainties were correlated to heterogeneity indices (HIs) calculated for each treatment field (38% < R{sup 2} < 50%). A NTCP increase of more than 10% (absolute) was observed for less than 2.9% (anatomy-based positioning) and 1.2% (fiducial-based positioning) of the studied OARs and patient shifts. TCP decreases larger than 10% (absolute) were seen for less than 2.2% of the target volumes or non-existent. EUD changes were up to 178% for OARs and 35% for target volumes. Conclusion: The influence of patient positioning uncertainties on proton range in therapy of small lesions in the human brain and target and OAR dosimetry were studied. Observed range uncertainties were correlated with HIs. The clinical practice of using multiple compensator

    To examine the relation of age with symptom severity and quality of life (QOL) in patients with fibromyalgia, and to compare physical and mental health of our female patients with those of the US female general population. We studied 978 patients with fibromyalgia from May 1, 2001 through April 30, 2004, and divided them into age groups of young (≤39 years), middle-aged (40-59 years), and older (≥60 years). They completed the Fibromyalgia Impact Questionnaire and the Short Form-36 Health Status Questionnaire (SF-36). Standardized SF-36 physical and mental health summary scores were compared with those of the US female general population of similar age. One-way analysis of variance and post hoc paired t test analyses were performed to detect differences across age groups. Pairwise comparison found young and middle-aged patients having worse fibromyalgia symptoms in all subscales except the anxiety subscale compared with older patients (P≤.01). Similarly, these young and middle-aged patients had worse QOL in the SF-36 mental component summary, as well as SF-36 general health perceptions, vitality, social functioning, and mental health index, compared with older patients (all Pfibromyalgia, with young and middle-aged patients having poorer QOL and worse fibromyalgia symptoms than do older patients. QOL in physical health was reduced more than in mental health, particularly in young patients, compared with the general population.

    Postoperative delirium is a common occurrence in older patients. However, reports of postoperative delirium in middle-aged patients are limited, and the underlying mechanism of delirium in this patient population is not clear. A 45-year-old man who developed postoperative delirium on the second day after partial laryngectomy. Interviews of the surgical team, patient, and patient's spouse revealed that the patient was psychologically stressed, but had not been diagnosed or treated. The patient also suffered impairment in physiological functioning and sleep disturbance after surgery. Postoperative delirium. The postoperative delirium was treated with an antipsychotic drug. The patient recovered well. Preoperative psychological stress, which is often undiagnosed and untreated, can increase the risk of postoperative delirium in middle-aged patients undergoing laryngectomy. Therefore, screening for psychological stress and implementing strategies to prevent delirium should be considered for patients who undergo laryngectomy, even if they are not in high-risk older age groups.

  13. Seroprevalence of Trypanosoma cruzi Infection in Students at the Seven-Fourteen Age Range, Londrina, PR, Brazil, in 1995

    Full Text Available Seropositivity for Chagas disease was evaluated in 834 children aged between 7 and 14 from the Municipal Teaching System in the district of Londrina, State of Paraná. A seroprevalence rate of 0.1% was found through the use of an indirect immunofluorescent test and an enzyme-linked immunosorbent assay. This low rate of seroprevalence provides evidence that the vectorial transmission of Chagas disease has been eliminated in Londrina. The main reason for the elimination of vectorial transmission of Trypanosoma cruzi infection, as evaluated by serological tests, may be a remarkable change in the economic structure of the northern region of Paraná in the 1960's. At that time coffee production was almost completely replaced by soy beans, wheat and grazing in the rural areas. This change deeply affected the rural ecology and caused an exodus of the population from rural to urban areas as well as a decrease in the total number of the population of that region. The measures introduced for controlling the disease through the Program of Chagas Disease Control established by the Fundação Nacional de Saúde of the Brazilian Ministry of Health, certainly, had a positive impact on the reduction of American trypanosomiasis prevalence in the area under study. However, it does not seem that this was the most relevant factor responsible for the elimination of vectorial transmission of Chagas disease in Londrina.

    Decreased health may have lowered the birth and survival rates of Steller sea lions ( Eumetopias jubatus) in the Gulf of Alaska and Aleutian Islands over the past 30 yr. Reference ranges for clinical hematology and serum chemistry parameters needed to assess the health of wild sea lion populations are limited. Here, blood parameters were serially measured in 12 captive female Steller sea lions ranging in age from 3 wk to 16 yr to establish baseline values and investigate age-related changes. Whether diving activity affects hematology parameters in animals swimming in the ocean compared with animals in a traditional aquarium setting was also examined. Almost all blood parameters measured exhibited significant changes with age. Many of the age-related changes reflected developmental life history changes, including a change in diet during weaning, an improvement of diving capacity, and the maturity of the immune system. Mean corpuscular hemoglobin and mean corpuscular volume were also higher in the ocean diving group compared with the aquarium group, likely reflecting responses to increased exercise regimes. These data provide ranges of hematology and serum chemistry values needed to evaluate and compare the health and nutritional status of captive and wild Steller sea lions.

    2002-01-01

    Aim: To create nomograms for renal size as measured from DMSA renal studies, and to test the nomograms for their ability to separate normal from abnormal kidneys. Method: Renal length was measured from posterior oblique views and renal area from posterior views. Results from 253 patients with bilateral normal kidneys were used to create nomograms for renal size relative to patient age, body height, weight or body surface area (BSA). The nomograms enclosed 95% of the normal kidneys, thus indicating the range for 95% confidence limits, and hence the specificity. Each nomogram was then tested against 46 hypertrophied kidneys and 46 damaged kidneys. Results: The results from nomograms of renal length and renal area, compared to age, body height, body weight and BSA are presented. For each nomogram, the range is presented as a fraction of the mean value, and the number of abnormal kidneys (hypertrophied or damaged) outside the normal range is presented as a percentage (indicating the sensitivity). Conclusion: Renal Area was no better than renal length for detecting abnormal kidneys. Patient age was the least useful method of normalisation. BSA normalisation produced the best results most frequently (narrower ranges and highest detection of abnormal kidneys)

    Aim: To investigate the clinical range and severity of radiological findings in a cohort of patients with primary ciliary dyskinesia (PCD) receiving tertiary care. Materials and methods: The case notes and clinical test results of 89 children attending the paediatric respiratory disease clinic at our institution were retrospectively analysed. Demographic details including age at diagnosis and common presenting signs and symptoms were studied. Results of chest radiographs, microscopy, and high-resolution computed tomography (HRCT) for quantification of lung damage were analysed. Results: In a cohort of 89 children with PCD, a presentation chest radiograph was available in 62% of patients (n = 55), with all but one demonstrating changes of bronchial wall thickening. HRCT of the lungs, available in 26 patients, were scored using the system described by Brody et al. analysing five specific features of lung disease, including bronchiectasis, mucus plugging, peribronchial thickening, parenchymal changes of consolidation, and ground-glass density, and focal air-trapping in each lobe. Peribronchial thickening was observed using HRCT in 25 patients, while 20 patients had bronchiectasis. Severity scores were highest for the middle and the lingular lobes. Conclusion: The radiographic findings of the largest reported cohort of patients with PCD are presented, with associated clinical findings. Dextrocardia remains the commonest finding on chest radiography. HRCT demonstrates peribronchial thickening and bronchiectasis, which is most marked in the lower zones. Radiological scoring techniques developed for assessment of cystic fibrosis can also be applied for the assessment of disease severity in this patient population.

    To examine spatial changes in rod-mediated function in relationship to local structural changes across the central retina in eyes with a spectrum of age-related macular degeneration (AMD) disease severity. Participants were categorized into five AMD severity groups based on fundus features. Scotopic thresholds were measured at 14 loci spanning ±18° along the vertical meridian from one eye of each of 42 participants (mean = 71.7 ± 9.9 years). Following a 30% bleach, dark adaptation was measured at eight loci (±12°). Rod intercept time (RIT) was defined from the time to detect a -3.1 log cd/m2 stimulus. RITslope was defined from the linear fit of RIT with decreasing retinal eccentricity. The presence of subretinal drusenoid deposits (SDD), ellipsoid (EZ) band disruption, and drusen at the test loci was evaluated using optical coherence tomography. Scotopic thresholds indicated greater rod function loss in the macula, which correlated with increasing AMD group severity. RITslope, which captures the spatial change in the rate of dark adaptation, increased with AMD severity (P < 0.0001). Three rod function phenotypes emerged: RF1, normal rod function; RF2, normal scotopic thresholds but slowed dark adaptation; and RF3, elevated scotopic thresholds with slowed dark adaptation. Dark adaptation was slowed at all loci with SDD or EZ band disruption, and at 32% of loci with no local structural changes. Three rod function phenotypes were defined from combined measurement of scotopic threshold and dark adaptation. Spatial changes in dark adaptation across the macula were captured with RITslope, which may be a useful outcome measure for functional studies of AMD.

  20. A fair range of choice: justifying maximum patient choice in the British National Health Service.

    Science.gov (United States)

    Wilmot, Stephen

    2007-06-01

    In this paper I put forward an ethical argument for the provision of extensive patient choice by the British National Health Service. I base this argument on traditional liberal rights to freedom of choice, on a welfare right to health care, and on a view of health as values-based. I argue that choice, to be ethically sustainable on this basis, must be values-based and rational. I also consider whether the British taxpayer may be persuadable with regard to the moral acceptability of patient choice, making use of Rawls' theory of political liberalism in this context. I identify issues that present problems in terms of public acceptance of choice, and also identify a boundary issue with regard to public health choices as against individual choices.

  1. Effect of Age on the Hemostatic Function in Patients with Degenerative Diseases of the Large Joints

    2013-06-01

    Full Text Available Background: Aging is associated with an increased hypercoagulable state. Degenerative diseases of the large joints are also accompanied by increased coagulation activity. We investigated the effect of age on the hemostatic function in patients with osteoarthritis. Material and Methods: The study included 192 patients with osteoarthritis admitted to the clinic for primary hip or knee arthroplasty. The patients were categorized into 5 age groups: the age group under 40 years, the 41–to-50 -year age group, the 51–to-60-year age group, the 61-to-70- year age group, and the age group over 70 years. The general blood clotting tests, platelet number, fibrinogen, antithrombin, protein C, TAT, D-dimer, vonWillebrand factor (vWF, PAI-1, ß-thromboglobulin were determined. Results: Among patients with osteoarthritis, the antithrombin III level significantly decreased by the age of 50; however, above the age of 60 there was a distinct decrease in platelet count, and over the age of 70 the activity of the extrinsic coagulation pathway and the plasminogen level dropped significantly. TAT and D-dimer levels were elevated in most of the patients. Conclusion: The decrease in platelet count coupled with the activity of the extrinsic coagulation pathway in elderly osteoarthritic patients may increase blood loss during total arthroplasty; also, the drop in the anticoagulant and fibrinolytic potential may play a negative role in strengthening the prothrombotic state during the postoperative period.

    The Espinhaco Range in the Grao Mogol region, center-north of Minas Gerais state, is composed by fine grained quartzites with large cross stratifications (Resplandescente Formation), which are covered with erosional unconformity by monomictic conglomerates, and medium to coarse grained quartzites (Grao Mogol Formation), both units belonging to the Espinhaco Supergroup, of Proterozoic age. At the locality known as 'Pedra Rica' (signify Rich Rock, an old diamond digging), rocks of these formations were sampled and separated detrital zircons to acquire U-Pb by Laser Ablation Inductively LA-ICPMS) ages. The analyzed grains are rounded to slightly rounded and show oscillatory zoning. The obtained results indicate a maximum depositional age of 1,595±20 Ma for the Resplandescente Formation, and 1,052±50 Ma for the Grao Mogol Formation. The comparison between the obtained data and the available ages for the Diamantina region and proximities, in the same diamond province, indicates a strong evidence for the existence of at least two primary mineralizing events in the basin, in the age range of 1.35 to 1.05 Ga.

    A significant number of patients treated for head and neck squamous cell cancer (HNSCC) undergo enteral tube feeding. Data suggest that avoiding enteral feeding can prevent long-term tube dependence and disuse of the swallowing mechanism which has been linked to complications such as prolonged dysphagia and esophageal constriction. We examined detailed dosimetric and clinical parameters to better identify those at risk of requiring enteral feeding. One hundred patients with advanced stage HNSCC were retrospectively analyzed after intensity-modulated radiation therapy (IMRT) to a median dose of 70 Gy (range: 60-75 Gy) with concurrent chemotherapy in nearly all cases (97%). Patients with significant weight loss (>10%) in the setting of severely reduced oral intake were referred for placement of a percutaneous endoscopic gastrostomy (PEG) tube. Detailed DVH parameters were collected for several structures. Univariate and multivariate analyses using logistic regression were used to determine clinical and dosimetric factors associated with needing enteral feeding. Dichotomous outcomes were tested using Fisher’s exact test and continuous variables between groups using the Wilcoxon rank-sum test. Thirty-three percent of patients required placement of an enteral feeding tube. The median time to tube placement was 25 days from start of treatment, after a median dose of 38 Gy. On univariate analysis, age (p = 0.0008), the DFH (Docetaxel/5-FU/Hydroxyurea) chemotherapy regimen (p = .042) and b.i.d treatment (P = 0.040) (used in limited cases on protocol) predicted need for enteral feeding. On multivariate analysis, age remained the single statistically significant factor (p = 0.003) regardless of other clinical features (e.g. BMI) and all radiation planning parameters. For patients 60 or older compared to younger adults, the odds ratio for needing enteral feeding was 4.188 (p = 0.0019). Older age was found to be the most significant risk factor for needing enteral feeding in

    Weathered felsite is associated with the late Campanian-Maastrichtian Pigeon Point Formation near Pescadero, California. Poorly exposed, its age and correlation are uncertain. Is it part of the Pigeon Point section west of the San Gregorio-Hosgri fault? Does it rest on Nacimiento block basement? Is it dextrally offset from the Oligocene Cambria Felsite, ~185 km to the southeast? Why is a calc-alkaline hypabyssal igneous rock intrusive into the outboard accretionary prism? To address these questions, we analyzed 43 oscillatory-zoned zircon crystals from three incipiently recrystallized pumpellyite ?? prehnite ?? laumontite-bearing Pescadero felsite samples by sensitive high-resolution ion microprobe-reverse geometry (SHRIMPRG) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) techniques. Thirty-three zircons gave late Mesozoic U-Pb ages, with single-grain values ranging from 81 to 167 Ma; ten have pre-Mesozoic, chiefl y Proterozoic ages. A group of the four youngest Pescadero zircons yielded an apparent maximum igneous age of ca. 86-90 Ma. Refl ecting broad age scatter and presence of partly digested sandstone inclusions, we interpret the rest of the zircons (perhaps all) as xenocrysts. Twenty-three zircons were separated and analyzed from two samples of the similar Cambria Felsite, yielding a unimodal 27 Ma U-Pb age. Clearly, the origin of the Upper Oligocene Cambria Felsite is different from that of the Upper Cretaceous Pescadero felsite; these rocks are not correlated, and do not constrain displacement along the San Gregorio-Hosgri fault. Peak ages differ slightly, but relative probability curves for Mesozoic and pre-Mesozoic Pescadero zircons compare well, for example, with abundant U-Pb age data for detrital zircons from Franciscan metaclastic strata ~100 km to the east in the Diablo Range- San Francisco Bay area, San Joaquin Great Valley Group turbidites, Upper Cretaceous Nacimiento block Franciscan strata, and Upper Cretaceous

    The difference between medial (MAOR) and anterior (AAOR) approaches for open reduction of developmental hip dysplasia in terms of risk for avascular necrosis (AVN) and need for further corrective surgery (FCS, femoral and/or acetabular osteotomy) is unclear. This study compared age-matched cohorts undergoing either MAOR or AAOR in terms of these 2 primary outcomes. Prognostic impact of presence of ossific nucleus at time of open reduction was also investigated. Institutional review board approval was obtained. Nineteen hips (14 patients) managed by MAOR were matched with 19 hips (18 patients) managed by AAOR based on age at operation (mean 6.0; range, 1.4 to 14.9 mo). Patients with neuromuscular conditions and known connective tissue disorders were excluded. Primary outcomes assessed at minimum 2 years' follow-up included radiographic evidence of AVN (Kalamchi and MacEwen) or requiring FCS. MAOR and AAOR cohorts were similar regarding age at open reduction, sex, laterality, and follow-up duration. One hip in each group had AVN before open reduction thus were excluded from AVN analysis. At minimum 2 years postoperatively (mean 6.2; range, 1.8 to 11.7 y), 4/18 (22%) MAOR and 5/18 (28%) AAOR met the same criteria for AVN (P=1.0). No predictors of AVN could be identified by regression analysis. Presence of an ossific nucleus preoperatively was not a protective factor from AVN (P=0.27). FCS was required in 4/19 (21%) MAOR and 7/19 (37%) AAOR hips (P=0.48). However, 7/12 (54%) hips failing closed reduction required FCS compared with 4/26 (16%) hips without prior failed closed reduction (P=0.024). Cox regression analysis showed that patients who failed closed reduction had an annual risk of requiring FCS approximately 6 times that of patients without a history of failed closed reduction (hazard ratio=6.1; 95% CI, 1.5-24.4; P=0.009), independent of surgical approach (P=0.55) or length of follow-up (P=0.78).

    The lower limbs of children aged 3-9 years present varying knock-knee deformities that have a direct impact on the diversification of the load-bearing axis of the valgus limb and on the modification of gait kinematics. The purpose of our study was to establish the reference values of knee alignment in a Greek population and whether this is linked to a change in the physical activity of children depending on the severity of the genu valgum. Using a clinical method, we measured both the tibiofemoral (TF) angle and the intermalleolar (IM) distance of the lower extremities of normal children. Subsequently, forms of the Netherlands Physical Activity Questionnaire (NPAQ) for young children and the Baecke questionnaire on habitual physical activity, modified especially for children, were completed by the parents. We examined both the development of the TF angle and the IM distance in relation to age and the degree of restriction of physical activity in relation to the severity of the genu valgum. We analysed 316 unaffected lower extremities in children aged 3-9 years. The average value of the TF angle starts around 7° at the age of 3 years and gradually decreases to 4° at the age of 7-8 years. The average value of the IM distance ranges over 3.5 cm at the age of 3 years and progressively decreases to 2 cm at the age of 7-8 years. Physical activity appears to be influenced by sex and the severity of the genu valgum. We provide age-specific values for limb alignment and joint orientation of the lower extremity in children aged 3-9 years. A statistical correlation between all indexes (sport, leisure time and total) of the Baecke and the NPAQs and measurements of genu valgum was noted depending on the severity of the valgus deformity.

    Non-adherence to bisphosphonates exposes the elderly female osteoporosis patients to an increased risk of fracture. This was one of the first studies to explore the relationship between medication adherence and self-perception of aging. Feelings of lacking control and expectations for negative events, beliefs of illness's chronic duration nature, and its linkage with aging were associated with of poor medication adherence. To examine the relationship between medication adherence to bisphosphonates and self-perception of aging in elderly female patients with osteoporosis. This was a cross-sectional survey. A convenience sample of 245 elderly female patients with osteoporosis prescribed regular oral bisphosphonate therapy was recruited from three tertiary hospitals in China. Sociodemographic and osteoporosis-related data, Morisky Medication Adherence Scale-8 (MMAS-8) and Aging Perceptions Questionnaire (APQ) data were collected. Mean adherence score measured by MMAS-8 was 4.46(SD = 1.91; range, 0.25-7.00). Percentages of good and poor adherence were 28.6 and 71.4 %, which showed a poor medication adherence. Six domains of APQ statistically significantly associated with medication adherence. Interestingly, with control of age, educational status, marital status, and symptoms accompanying osteoporosis as covariates in the multivariate linear regression model, the effects of three domains disappeared. Significantly, worse adherence was observed in those patients who had higher feelings of lack of control, more expectations for negative events, more beliefs of osteoporosis's chronic duration nature and its linkage with aging. We conclude that feelings of lacking control, expectations for negative events, beliefs of illness's chronic duration nature, and its linkage with aging were associated with poor medication adherence in elderly female patients with osteoporosis. Concerns about self-perception of aging need to be addressed in order to improve medication adherence.

    Evaluating the risk of falling of a geriatric rheumatic patient plays an essential role not only in planning and carrying out the physiotherapeutic process. The consequences of falls may be different and, although they do not always result in serious repercussions such as fractures or injuries, it is sufficient that they generate the fear of falling and cause a significant reduction in physical activity. Assessing functional capacity to define the risk of falling is of utmost importance in the case of patients after joint arthroplasty surgeries. The specificity of rheumatic patient's falls is determined by numerous factors. It is not always possible to avoid them. However, it becomes vital to include fall prevention in the rehabilitation process as well as to prepare the house for the needs of an elderly person so that they are safe and as self-dependent as possible.

    The gonad shielding is used to minimize the impact of the exposure to gonads when Abdomen, Plevis and Hip X-ray inspections are conducted on radiation impressionable pediatric patients. By the way, the gonad is palpable difficult and impossible to check visually because it's a sensitive area, so tests are conducted with the approximate location of shielding, thereby appearing problems of not shielding gonads accurately. Accordingly, this study produced shields by age and gender of pediatric patients and studied the method of positioning shields with ASIS as a reference point without palpable sensitive areas, and tried to evaluate its usability. The study surveyed 30 pediatric patients by gender and age, who came and got inspected in Department of Radiology, our hospital from February 2012 to January 2014 and obtained the value of tolerance by measuring the average size of the pelvis using the distance measurement function of Infinitt Piview with the images stored in the PACS and producing shields by age and gender of pediatric patients and specifying the areas at random for the comparative analysis of pre- and post-using. It calculated the technology statistics (mean±SD) with the value of tolerance measured the length using SPSS 12.0 statistical program. As for boys, differences in the tolerance range of pre- and post-using shields were 2.69 mm in case of 1 year old, 2.58 mm in 2 years, 2.37 mm in 3 years, 2.815 mm in 4-5 years, 2.043 mm in 7-10 years, and as for girls,1.92 mm in 1-2 years, 1.75 mm in 3-4 years, 2.52 mm in 5-6 years and 1.93 mm in 7-10. After analyzing the pre- and post-using shields for all of boys and girls, there were statistically significant differences (P<0.050). It is considered that we can minimize the exposure to gonads and get a better video for diagnosis in testing high biological impressionable pediatric, if we use shields correctly with ASIS as a reference point considering its shape and size by age and gender in Abdomen, Plevis

    Purpose: Given the radiation concerns inherent to the x-ray modalities, accurately estimating the radiation doses that patients receive during different imaging modalities is crucial. This study estimated organ doses, effective doses, and risk indices for the three clinical chest x-ray imaging techniques (chest radiography, tomosynthesis, and CT) using 59 anatomically variable voxelized phantoms and Monte Carlo simulation methods. Methods: A total of 59 computational anthropomorphic male and female extended cardiac-torso (XCAT) adult phantoms were used in this study. Organ doses and effective doses were estimated for a clinical radiography system with the capability of conducting chest radiography and tomosynthesis (Definium 8000, VolumeRAD, GE Healthcare) and a clinical CT system (LightSpeed VCT, GE Healthcare). A Monte Carlo dose simulation program (PENELOPE, version 2006, Universitat de Barcelona, Spain) was used to mimic these two clinical systems. The Duke University (Durham, NC) technique charts were used to determine the clinical techniques for the radiographic modalities. An exponential relationship between CTDI vol and patient diameter was used to determine the absolute dose values for CT. The simulations of the two clinical systems compute organ and tissue doses, which were then used to calculate effective dose and risk index. The calculation of the two dose metrics used the tissue weighting factors from ICRP Publication 103 and BEIR VII report. Results: The average effective dose of the chest posteroanterior examination was found to be 0.04 mSv, which was 1.3% that of the chest CT examination. The average effective dose of the chest tomosynthesis examination was found to be about ten times that of the chest posteroanterior examination and about 12% that of the chest CT examination. With increasing patient average chest diameter, both the effective dose and risk index for CT increased considerably in an exponential fashion, while these two dose metrics

    Full Text Available Abstract Background Metabolic acidosis leads to chronic kidney disease (CKD progression. The guidelines recommend a lower limit of serum bicarbonate level, but no upper limit. For serum bicarbonate level to be clinically useful as a therapeutic target marker, it is necessary to investigate the target serum bicarbonate level within the normal range to prevent CKD progression. Methods One hundred and thirteen elderly CKD patients, whose serum bicarbonate level was controlled within the normal range, were enrolled in this retrospective cohort study in Ibaraki, Japan. Outcome was defined as a decrease of 25% or more in estimated glomerular filtration rate (eGFR or starting dialysis. We used Cox proportional hazard models adjusted for patients’ characteristics to examine the association between serum bicarbonate level and the outcome. Results Female patients were 36.3%: average age (SD, 70.4 (6.6 years; eGFR, 25.7 (13.6 ml/min/1.73 m2; serum bicarbonate level, 27.4 (3.2 mEq/l. Patients with the lowest quartile of serum bicarbonate levels [23.4 (1.8 mEq/l] showed a high risk of CKD progression compared with patients with high serum bicarbonate levels [28.8 (2.3 mEq/l]: adjusted hazard ratio (HR, 3.511 (95% CI, 1.342-9.186. A 1 mEq/l increase in serum bicarbonate level was associated with a low risk of CKD progression: adjusted HR, 0.791 [95% confidence interval (CI, 0.684-0.914]. Conclusions In elderly CKD patients, our findings suggest that serum bicarbonate level is independently associated with CKD progression, and that a high serum bicarbonate level is associated with a low risk of CKD progression. A high target serum bicarbonate level within the normal range may be effective for preventing CKD progression.

    To assess indications, incidence, patient experience, and outcomes of orthognathic surgery in patients over 40 years of age. This was a retrospective cohort study of all patients who underwent orthognathic surgical procedures at Massachusetts General Hospital from 1995 to 2012. Demographic variables, including age, gender, indications, date, and type of operation, were documented. Patients were divided into 2 groups by date of operation: 1) 1995 to 2002 and 2) 2003 to 2012. The predictor variable was age (>40 vs orthognathic surgery varies by age and gender. Older patients, particularly men, tend to seek treatment for functional rather than esthetic reasons. Patients older than 40 years had longer hospital stays and an increased rate of postoperative hardware removal. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons.

    Returning to society plays an important role in improving the quality of life in maintenance hemodialysis (MHD) patients, and retention of employment is one of the core enablers. The study is to assess the employment status and to determine the variables for unemployment in Chinese MHD patients. Prevalent MHD patients from four dialysis centers in Shanghai China were enrolled. We assessed patients' employment status, current social functioning, hemodialysis modality, annual income and general health condition. Among current unemployed working-age patients, the reasons of quitting jobs and willingness of being reemployed were evaluated. A total of 231 patients were studied, among which 114 patients were unemployed 1 year before hemodialysis. Among 117 employed patients, 16 patients quitted jobs before dialysis inception, while 49 patients quitted jobs at the initiation of HD, and 26 patients followed after a few months' HD. The main reasons for ceasing employment were physical insufficiency, conflict between dialysis and work schedules, lack of support from employers and resistance from family members. Among the 166 patients who were in their working age, 26 patients were employed. The unemployed patients had the characters of elder age, lower education level, higher annual family income, higher female ratio, lower blood flow, lower physical functioning, and social functioning and lower frequency of weekend hemodialysis and HDF/HF. Among the 140 unemployed patients, only 47 patients had the willingness of being reemployed. Their unemployment status was positively associated with elder age ((OR) 3.13, 95% CI, 1.08-9.1), lower education level ((OR) 1.97, 95% CI, 1.05-5.92), and higher family income ((OR) 7.75, 95% CI, 2.49-24.14). Ratio of employment and willingness of being reemployed was low in MHD working-age patients. Lack of social and family's support also hampered patient's returning to society except for the HD treatment quality.

However, it becomes vital to include fall prevention in the rehabilitation process as well as to prepare the house for the needs of an elderly person so that they are safe and as self-dependent as possible.

    Evaluating the risk of falling of a geriatric rheumatic patient plays an essential role not only in planning and carrying out the physiotherapeutic process. The consequences of falls may be different and, although they do not always result in serious repercussions such as fractures or injuries, it is sufficient that they generate the fear of falling and cause a significant reduction in physical activity. Assessing functional capacity to define the risk of falling is of utmost importance in th...

    Anxiety and trauma-related disorders are among the most prevalent and disabling medical conditions in the United States, and posttraumatic stress disorder in particular exacts a tremendous public health toll. We examined the tolerability and anxiolytic efficacy of neuropeptide Y administered via an intranasal route in patients with posttraumatic stress disorder. Twenty-six individuals were randomized in a cross-over, single ascending dose study into 1 of 5 cohorts: 1.4 mg (n=3), 2.8 mg (n=6), 4.6 mg (n=5), 6.8 mg (n=6), and 9.6 mg (n=6). Each individual was dosed with neuropeptide Y or placebo on separate treatment days 1 week apart in random order under double-blind conditions. Assessments were conducted at baseline and following a trauma script symptom provocation procedure subsequent to dosing. Occurrence of adverse events represented the primary tolerability outcome. The difference between treatment conditions on anxiety as measured by the Beck Anxiety Inventory and the State-Trait Anxiety Inventory immediately following the trauma script represented efficacy outcomes. Twenty-four individuals completed both treatment days. Neuropeptide Y was well tolerated up to and including the highest dose. There was a significant interaction between treatment and dose; higher doses of neuropeptide Y were associated with a greater treatment effect, favoring neuropeptide Y over placebo on Beck Anxiety Inventory score (F1,20=4.95, P=.038). There was no significant interaction for State-Trait Anxiety Inventory score. Our study suggests that a single dose of neuropeptide Y is well tolerated up to 9.6 mg and may be associated with anxiolytic effects. Future studies exploring the safety and efficacy of neuropeptide Y in stress-related disorders are warranted.

    Conclusions: The range of lesions seen in Saudi geriatric patients were similar to those reported for other parts of the world, although the lesions were more similar to those reported from developing countries. The very high rate of oral cancer, however, is expected to take the majority of the resources allocated to geriatric oral health care, except if a strong, population-based prevention program is initiated immediately.

    Intellectual disabilities are often associated with bilateral or diffuse morphologic brain damage. The chances of becoming seizure free after focal surgery are therefore considered to be worse in patients with intellectual disabilities. The risk of postoperative cognitive deficits could increase because diffuse brain damage lowers the patient's ability to compensate for surgically induced deficits. Several studies in adult patients have indicated that IQ alone is not a good predictor of postoperative cognitive and seizure outcome. Our study evaluated this subject in children and adolescents. Pediatric patients with intellectual disabilities (IQ intelligence (IQ between 71 and 85), or average-range intelligence (IQ > 85) were matched according to several clinical and etiologic criteria to determine the influence of IQ (N = 66). No dependency of seizure outcome, postoperative cognitive development, and behavioral outcome on the IQ level was found. All groups slightly improved in attention while memory functions tended to decrease and executive functions were stable. School placement remained unchanged for the majority of patients. Between 67 and 78% were seizure free 1 year after surgery (Engel outcome class I). IQ alone is not a good predictor of postoperative outcome in pediatric patients with epilepsy. As with patients of average-range intelligence, the decision to operate on patients with a low level of intelligence should depend on the results of the presurgical diagnostics. If the results of the neuropsychological examination indicate diffuse functional impairment, this should not hinder further steps, if all other findings are consistent.

    In an aging world, maintaining good health and independence for as long as possible is essential. Instead of hospitalization or institutionalization, the elderly with chronic conditions, especially those with cognitive impairment, can be assisted in their own environment with numerous 'smart' devices that support them in their activity of daily living. A "smart home" is a residence equipped with technology that facilitates monitoring of residents to improve quality of life and promote physical independence, as well as to reduce caregiver burden. Several projects worldwide have been conducted, but some ethical and legal issues are still unresolved and, at present, there is no evidence of the effects of smart homes on health outcomes. Randomized controlled trials are needed to understand the plus and minuses of these projects, but this will only be possible with a widespread proliferation and penetration of smart homes in the social network.

    Purpose/Objective: Palliative radiation therapy represents an important treatment option among patients with advanced cancer, although research shows decreased use among older patients. This study evaluated age-related patterns of palliative radiation use among an elderly Medicare population. Methods and Materials: We identified 63,221 patients with metastatic lung, breast, prostate, or colorectal cancer diagnosed between 2000 and 2007 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Receipt of palliative radiation therapy was extracted from Medicare claims. Multivariate Poisson regression analysis determined residual age-related disparity in the receipt of palliative radiation therapy after controlling for confounding covariates including age-related differences in patient and demographic covariates, length of life, and patient preferences for aggressive cancer therapy. Results: The use of radiation decreased steadily with increasing patient age. Forty-two percent of patients aged 66 to 69 received palliative radiation therapy. Rates of palliative radiation decreased to 38%, 32%, 24%, and 14% among patients aged 70 to 74, 75 to 79, 80 to 84, and over 85, respectively. Multivariate analysis found that confounding covariates attenuated these findings, although the decreased relative rate of palliative radiation therapy among the elderly remained clinically and statistically significant. On multivariate analysis, compared to patients 66 to 69 years old, those aged 70 to 74, 75 to 79, 80 to 84, and over 85 had a 7%, 15%, 25%, and 44% decreased rate of receiving palliative radiation, respectively (all P<.0001). Conclusions: Age disparity with palliative radiation therapy exists among older cancer patients. Further research should strive to identify barriers to palliative radiation among the elderly, and extra effort should be made to give older patients the opportunity to receive this quality of life-enhancing treatment at the end

  11. Viscoplastic behavior of zirconium alloys in the temperatures range 20 deg C - 400 deg C: characterization and modeling of strain ageing phenomena

    2006-10-01

    The anomalous strain rate sensitivity of zirconium alloys over the temperatures range 20-600 C has been widely reported in the literature. This unconventional behavior is related to the existence of strain ageing phenomenon which results from the combined action of thermally activated diffusion of foreign atoms to and along dislocation cores and the long range of dislocations interactions. The important role of interstitial and substitutional atoms in zirconium alloys, responsible for strain ageing and the lack of information about the domain where strain ageing is active have not been yet adequately characterized because of the multiplicity of alloying elements and chemical impurities. The aim of this work is to characterize experimentally the range of temperatures and strain rates where strain ageing is active on the macroscopic and mesoscopic scales. We propose also a predictive approach of the strain ageing effects, using the macroscopic strain ageing model suggested by McCormick (McCormick, 1988; Zhang et al., 2000). Specific zirconium alloys were elaborated starting from a crystal bar of zirconium with 2.2 wt% hafnium and very low oxygen content (80 wt ppm), called ZrHf. Another substitutional atom was added to the solid solution under the form of 1 wt% niobium. Some zirconium alloys were doped with oxygen, others were not. All of them were characterized by various mechanical tests (standard tensile tests, tensile tests with strain rate changes, relaxation tests with unloading). The experimental results were compared with those for the standard oxygen doped zirconium alloy (1300 wt ppm) studied by Pujol (Pujol, 1994) and called Zr702. The following experimental evidences of the age-hardening phenomena were collected and then modeled: 1) low and/or negative strain rate sensitivity around 200-300 C, 2) creep arrest at 200 C, 3) relaxation arrest at 200 C and 300 C, 4) plastic strain heterogeneities observed in laser extensometry on the millimeter scale

    The Qaidam Basin is the largest intermountain basin within the Tibetan Plateau. The Cenozoic sedimentary flling characteristics of the basin was significantly influenced by the surrounding tectonic belt, such as the Altyn Tagh Range to the north-west and Qimen Tagh Range to the south. The tectonic evolution of the Qimen Tagh Range and the structural relationship between the Qaidam Basin and Qimen Tagh Range remain controversial. To address these issues, we analyzed thousands of heavy mineral data, 720 detrital zircon ages and seismic data of the Qaidam Basin. Based on the regional geological framework and our kinematic analyses, the Cenozoic tectonic evolution of the Qimen Tagh Range can be divided into two stages. From the Early Eocene to the Middle Miocene, the Devonian (400-360 Ma) and Permian to Triassic (300-200 Ma) zircons which were sourced from the Qimen Tagh Range and the heavy mineral assemblage of zircon-leucoxene-garnet-sphene on the north flank of the Qimen Tagh Range indicated that the Qimen Tagh Range has been exhumed before the Eocene and acted as the primary provenance of the Qaidam Basin. The Kunbei fault system (i.e. the Kunbei, Arlar and Hongliuquan faults) in the southwest of the Qaidam Basin, which can be seen as a natural study window of the Qimen Tagh Range, was characterized by left-lateral strike-slip faults and weak south-dipping thrust faults based on the seismic sections. This strike-slip motion was generated by the uplift of the Tibetan Plateau caused by the onset of the Indian-Eurasian collision. Since the Middle Miocene, the primary mineral assemblages along the northern flank of the Qimen Tagh Range changed from the zircon-leucoxene-garnet-sphene assemblage to the epidote-hornblende-garnet-leucoxene assemblage. Simultaneously, the Kunbei fault system underwent intense south-dipping thrusting, and a nearly 2.2-km uplift can be observed in the hanging wall of the Arlar fault. We attributed these variations to the rapid uplift event of

    Purpose: To evaluate the robustness of head and neck plans for treatment with intensity modulated proton therapy to range and setup errors, and to establish robustness parameters for the planning of future head and neck treatments. Methods and Materials: Ten patients previously treated were evaluated in terms of robustness to range and setup errors. Error bar dose distributions were generated for each plan, from which several metrics were extracted and used to define a robustness database of acceptable parameters over all analyzed plans. The patients were treated in sequentially delivered series, and plans were evaluated for both the first series and for the combined error over the whole treatment. To demonstrate the application of such a database in the head and neck, for 1 patient, an alternative treatment plan was generated using a simultaneous integrated boost (SIB) approach and plans of differing numbers of fields. Results: The robustness database for the treatment of head and neck patients is presented. In an example case, comparison of single and multiple field plans against the database show clear improvements in robustness by using multiple fields. A comparison of sequentially delivered series and an SIB approach for this patient show both to be of comparable robustness, although the SIB approach shows a slightly greater sensitivity to uncertainties. Conclusions: A robustness database was created for the treatment of head and neck patients with intensity modulated proton therapy based on previous clinical experience. This will allow the identification of future plans that may benefit from alternative planning approaches to improve robustness.

    Range Compensator used for proton therapy compensates the proton beam dose which delivers to the normal tissues according to the Target's Distal Margin dose. We are going to check the improvement of dose on the target part by comparing the dose of PTV and OAR according to applying in different method of Smooth Thickness of Range Compensator which is used in brain tumor therapy. For 10 brain tumor patients taking proton therapy in National Cancer Center, Apply Smooth Thickness applied in Range Compensator in order from one to five by using Compensator Editor of Eclipse Proton Planning System(Version 10.0, Varian, USA). The therapy plan algorithm used Proton Convolution Superposition(version 8.1.20 or 10.0.28), and we compared Dmax, Dmin, Homogeneity Index, Conformity Index and OAR dose around tumor by applying Smooth Thickness in phase. When Smooth Thickness was applied from one to five, the Dmax of PTV was decreased max 4.3%, minimum at 0.8 and average of 1.81%. Dmin increased max 1.8%, min 1.8% and average. Difference between max dose and minimum dose decreased at max 5.9% min 1.4% and average 2.6%. Homogeneity Index decreased average of 0.018 and Conformity Index didn't had a meaningful change. OAR dose decreased in Brain Stem at max 1.6%, min 0.1% and average 0.6% and in Optic Chiasm max 1.3%, min 0.3%, and average 0.5%. However, patient C and patient E had an increase each 0.3% and 0.6%. Additionally, in Rt. Optic Nerve, there was a decrease at max 1.5%, min 0.3%, and average 0.8%, however, patient B had 0.1% increase. In Lt. Optic Nerve, there was a decrease at max 1.8%, min 0.3%, and average 0.7%, however, patient H had 0.4 increase. As Smooth Thickness of Range Compensator which is used as the proton treatment for brain tumor patients is applied in stages, the resolution of Compensator increased and as a result the most optimized amount of proton beam dose can be delivered. This is considered to be able to irradiate the equal amount at PTV and

    Objective: To evaluate the in-hospital mortality of acute myocardial infarction among different age groups. Subjects and Methods: The subjects were 460 admitted patients of acute myocardial infarction who fulfilled our inclusion criteria. Patients were divided into four age groups. Group-I included patients in 20-40 years, group-II (41-50 years), group-III (51-60 years) and group-IV (>60 years). Mortality was compared between different age groups by Chi-square and linear-regression models. Results: The total in-hospital mortality was 16.7%. It gradually increased from 5.6% in group-I (20-40 years) patients to 21% in group-IV (>60 years) patients. While mortality in groups group-II (41-50 years) and group-III (51-60 years) patients was 16.7% and 18.6% respectively. A marked increase in mortality was noted with increase in age. Group- IV (>60 years) patients presented 2 hours late to the hospital than the group-I (20-40 years) patients. There was no statistical difference in site of infarction in different age groups. Old age (group-IV i.e. >60 years old) was more associated with heart failure (higher Killip class) on presentation. Lesser number of patients in group-IV received thrombolytic therapy than group-I. Only 31.09% patients in group-IV and 62.5% patients in group-I received streptokinase therapy respectively. Conclusion: In patients with acute myocardial infarction age was a powerful independent predictor of in-hospital mortality and complications. (author)

    The goal of this study was to explore neural activities of schizophrenic patients related to current age including the age of onset and also we examined the correlation patterns between age and neural correlates. 21 patients with schizophrenia (female/male; 10/11, mean age; 36.1 11.2) participated in this study and all patients were evaluated by criteria of DSM-IV as a schizophrenia patient. Exclusion criteria included inability to give informed consent and a history of significant neurological illness. 99mTc-ECD brain perfusion SPECT images were obtained from 21 schizophrenic patients. Using SPM (statistical parametric mapping), all images were normalized to a SPECT template (MNI template) and then smoothed. We performed an ANCOVA analysis with current age (covariate variable) and the age of onset (nuisance variable). The correlation was analyzed into positive and negative patterns. Findings are reported as a Z scores with a significance threshold of p < 0.005 (uncorrected) and a minimum cluster size of 10. Significant difference was found between current age and premorbid age (p < 0.05). Cerebral regions that were positively correlated with current age were observed in the middle frontal gyrus and the superior frontal gyrus bilaterally, the left precentral gyrus (Brodmann's area; BA 9) and the right inferior frontal gyrus (BA 46). Also, in relation to negative correlations, there were many regions in the right posterior cingulate gyrus (BA 30) and the left cuneus (BA 30), middle temporal gyrus (BA 21) and superior temporal gyrus (BA 13, 39). Additionally, the occipital regions were found in the right cuneus (BA 18) including the right middle occipital gyrus (BA 18) and right lingual gyrus (BA 19). Age effect in schizophrenic patients was observed in the dorsolateral prefrontal cortex with positive correlation. We suggest that the dorsolateral prefrontal cortex activity which is important for cognitive task performance is related to an increase of patients age

    The age at menarche reflects a pubertal girl's physiologic maturity. The aims of this study were to evaluate the relationship between the age at menarche and skeletal maturation in female orthodontic patients. Hand-wrist radiographs and lateral cephalometric radiographs from 304 adolescent female subjects (age, 8-18.9 years) were selected from the files of the Department of Orthodontics, National Taiwan University Hospital (NTUH). Hand-wrist bone maturation stages were assessed using the NTUH Skeletal Maturation Index (NTUH-SMI). Cervical vertebral maturation stages (CVMS) were determined using the latest CVMS Index. Menarcheal ages were self-reported by the patients and verified by the patients' mothers. The relationships between the NTUH-SMI or CVM stages and menarcheal status were investigated. More than 90% of the 148 subjects who had already attained menstruation had skeletal maturation beyond the NTUH-SMI stage four or CVMS III. However, the subjects who had never experienced menarche mostly had skeletal maturation before NTUH-SMI stage five or CVMS IV. During the period of orthodontic treatment, 19 females experienced their menarche. The mean age at menarche for the 167 female patients in total was 11.97 years. In average, menarche occurred between NTUH-SMI stages four and five or between CVM stages III and IV. The percentage of girls with menses increased from 1.2% at age 9 to 6.6% at age 10, 39.5% at age 11, 81.4% at age 12, 97% at age 13, and 100% at age 14. Compared with the results obtained 20 years previously, we found a downward shift of 0.47 years per decade for the mean age at menarche in female orthodontic patients. The majority of female orthodontic patients have passed the pubertal growth spurt when they experience their menarche. Menarche usually follows the pubertal growth spurt by about 1 year and occurs after NTUH-SMI stage four or CVMS III.

    Young, active candidates for total shoulder arthroplasty (TSA) are a unique group of patients. Not only do they demand longevity and improved function, but they also desire a return to physical activities. To determine the rate of return to sports in patients aged ≤55 years undergoing TSA. Case series; Level of evidence, 4. This was a retrospective review of consecutive patients who underwent anatomic TSA at a single institution. Exclusion criteria included age at the time of surgery >55 years and sports questionnaire, American Shoulder and Elbow Surgeons (ASES) score, and visual analog scale (VAS) score. From 70 eligible patients, 59 patients (61 shoulders) were included with an average follow-up of 61.0 months (range, 25-103 months) and average age at the time of surgery of 48.9 years (range, 25-55 years). The average VAS score improved from 5.6 to 0.9 ( P sports. Moreover, patients in 96.4% of shoulders (55/57) restarted at least 1 sport at an average of 6.7 months. Direct rates of return were as follows: fitness sports (97.2%), golf (93.3%), singles tennis (87.5%), swimming (77.7%), basketball (75.0%), and flag football (66.7%). Patients in 47 shoulders (82.4%) returned to a similar or higher level of sports; 90.3% returned to high-demand sports, and 83.8% returned to high upper extremity sports. There was no significant difference in rates of return to sports by body mass index, sex, age, preoperative diagnosis, revision status, and dominant extremity. In patients aged ≤55 years undergoing TSA, there was a 96.4% rate of return to ≥1 previous sports at an average of 6.7 months. Furthermore, at an average follow-up of 61.0 months, no patients needed revision of their glenoid component, despite an 83.8% rate of return to high upper extremity sports. While caution should still be advised in young, active patients undergoing TSA, these results demonstrate a high satisfaction rate and improved ability to return to most sports after surgery.

    To examine age- and age-related differences in recall of information provided during oncology consultations. Two hundred sixty patients with cancer diagnosed with heterogeneous cancers, seeing a medical or radiation oncologist for the first time, participated in the study. Patients completed questionnaires assessing information needs and anxiety. Recall of information provided was measured using a structured telephone interview in which patients were prompted to remember details physicians gave about diagnosis, prognosis, and treatment. Recall was checked against the actual communication in audio-recordings of the consultations. Recall decreased significantly with age, but only when total amount of information presented was taken into account. This indicates that if more information is discussed, older patients have more trouble remembering the information than younger ones. In addition, recall was selectively influenced by prognosis. First, patients with a poorer prognosis recalled less. Next, the more information was provided about prognosis, the less information patients recalled, regardless of their actual prognosis. Recall is not simply a function of patient age. Age only predicts recall when controlling for amount of information presented. Both prognosis and information about prognosis are better predictors of recall than age. These results provide important insights into intervention strategies to improve information recall in patients with cancer.

    To compare macular choroidal thickness between patients older than 65 years with early atrophic age-related macular degeneration (AMD) and normals. This was a consecutive, cross-sectional observational study. Enhanced depth imaging spectral-domain optical coherence tomography using horizontal raster scanning at 12 locations throughout the macula was performed in one eye of consecutive patients presenting with large soft drusen alone, drusen with additional features of early AMD, or a normal fundus. Choroidal thickness was measured at 7 points for each raster scan in the central 3 mm of the macula (total 84 points per eye). In addition, a single subfoveolar measurement was obtained for each eye. One hundred fifty eyes of 150 patients were included. There was no significant difference between mean refractive error for each diagnosis category via one-way ANOVA (P = 0.451). Mean macular choroidal thickness (CT) was 235 ± 49 μm (range, 125-334 μm; median 222 μm) for normals, 161 ± 39 μm (range, 89-260 μm; median = 158 μm) for the drusen group, and 115 ± 40 μm (range, 22-256 μm; median = 112 μm) for patients with AMD. Mean macular CT was significantly different via one-way ANOVA among all diagnosis categories (P < 0.001). The presence of features of early AMD without geographic atrophy and/or soft drusen alone is associated with decreased mean macular CT in vivo compared to that in patients with no chorioretinal pathology. Using enhanced depth imaging, measurement of a single subfoveolar choroidal thickness is highly correlated to mean central macular CT.

    The purpose of this study was to analyze factors affecting proton stopping-power-ratio (SPR) estimations and range uncertainties in proton therapy planning using the standard stoichiometric calibration. The SPR uncertainties were grouped into five categories according to their origins and then estimated based on previously published reports or measurements. For the first time, the impact of tissue composition variations on SPR estimation was assessed and the uncertainty estimates of each category were determined for low-density (lung), soft, and high-density (bone) tissues. A composite, 95th percentile water-equivalent-thickness uncertainty was calculated from multiple beam directions in 15 patients with various types of cancer undergoing proton therapy. The SPR uncertainties (1σ) were quite different (ranging from 1.6% to 5.0%) in different tissue groups, although the final combined uncertainty (95th percentile) for different treatment sites was fairly consistent at 3.0-3.4%, primarily because soft tissue is the dominant tissue type in the human body. The dominant contributing factor for uncertainties in soft tissues was the degeneracy of Hounsfield numbers in the presence of tissue composition variations. To reduce the overall uncertainties in SPR estimation, the use of dual-energy computed tomography is suggested. The values recommended in this study based on typical treatment sites and a small group of patients roughly agree with the commonly referenced value (3.5%) used for margin design. By using tissue-specific range uncertainties, one could estimate the beam-specific range margin by accounting for different types and amounts of tissues along a beam, which may allow for customization of range uncertainty for each beam direction.

    Purpose: We retrospectively evaluate the dosimetric impact of a 3.5% range uncertainty on CTV coverage and normal organ toxicity for a cohort of brain patients. Methods: Twenty treatment plans involving 20 brain cancer patients treated with Mevions S250 were reviewed. Forty uncertain plans were made by changing the ranges in original plans by ±3.5% while keeping all devices unchanged. Fidelity to the original plans was evaluated with gamma index. Changes in generalized equivalent uniform dose (gEUD) were reported for the following structures: CTV coverage, brainstem, optic chiasm, and optic nerves. Comparisons were made by plotting the relevant endpoints from the uncertain plans as a function of the same endpoints from the original clinical plan. Results: Gamma-index analysis resulted in a 50% pass rate of the uncertain plans using a 90% passing rate and 3%/3mm criterion. A 9.5% decrease in the slope of gEUD plot for the CTV was observed for the 3.5% downward range shift. However, the change in slope did not result in a gEUD change greater than 1.1% for the CTV. The slopes of the gEUD plots for normal structures increased by 3.1% 3.9% 2.4% and 0.2% for the chiasm, brainstem, left optic nerve and right optic nerve respectively. The maximum deviation from the gEUD of the clinical plan for normal structures was: 64% in the chiasm, 31% for the brainstem, and 19% for both optic nerves. Conclusion: A retrospective review shows moderate radiobiological impact of range uncertainty in passively scattered proton therapy with sporadic catastrophe. The linear regression analysis on the statistical data indicates a systematic deviation of gEUD from treatment planning in the light of range uncertainty.

    To quantify differences in active cervical range of motion (aCROM) between patients with neck pain and those without neck pain, in patients with whiplash-associated disorders (WADs) and nontraumatic neck pain, and in patients with acute complaints versus those with chronic complaints. Seven bibliographic databases were searched from inception to April 2015. In addition, a manual search was performed. Full articles on a numerical comparison of aCROM in patients with neck pain and asymptomatic control persons of similar ages were included. Two reviewers independently selected studies and assessed risk of bias. Two reviewers extracted the data. Pooled mean differences of aCROM were calculated using a random-effects model. The search yielded 6261 hits; 27 articles (2366 participants, 13 low risk of bias) met the inclusion criteria. The neck pain group showed less aCROM in all movement directions compared with persons without neck pain. Mean differences ranged from -7.04° (95% CI, -9.70° to -4.38°) for right lateral bending (11 studies) to -89.59° (95% CI, -131.67° to -47.51°) for total aCROM (4 studies). Patients with WADs had less aCROM than patients with nontraumatic neck pain. No conclusive differences in aCROM were found between patients with acute and patients with chronic complaints. Patients with neck pain have a significantly decreased aCROM compared with persons without neck pain, and patients with WADs have less aCROM than those with nontraumatic neck pain.

    Two experiments examined 4- to 11-year-olds' and adults' performance (N = 350) on two variants of a Stroop-like card task: the day-night task (say 'day' when shown a moon and 'night' when shown a sun) and a new happy-sad task (say 'happy' for a sad face and 'sad' for a happy face). Experiment 1 featured colored cartoon drawings. In Experiment 2, the happy-sad task featured photographs, and pictures for both measures were gray scale. All age groups made more errors and took longer to respond to the happy-sad versus the day-night versions. Unlike the day-night task, the happy-sad task did not suffer from ceiling effects, even in adults. The happy-sad task provides a methodological advance for measuring executive function across a wide age range.

    The hypothesis that exposure to ionizing radiation accelerates the aging process has been actively investigated at ABCC-RERF since 1958, when longitudinal cohort studies of the Adult Health Study (AHS) and the Life Span Study (LSS) were initiated. In their 1975 overall review of aging studies related to the atomic bomb (A-bomb) survivors, Finch and Beebe concluded that while most studies had shown no correlation between aging and radiation exposure, they had not involved the large numbers of subjects required to provide strong evidence for or against the hypothesis. Extending LSS mortality data up to 1978 did not alter the earlier conclusion that any observed life-shortening was associated primarily with cancer induction rather than with any nonspecific cause. The results of aging studies conducted during the intervening 15 years using data from the same populations are reviewed in the present paper. Using clinical, epidemiological, and laboratory techniques, a broad spectrum of aging parameters have been studied, such as postmortem morphological changes, tests of functional capacity, physical tests and measurements, laboratory tests, tissue changes, and morbidity. With respect to the aging process, the overall results have not been consistent and are generally thought to show no relation to radiation exposure. Although some preliminary results suggest a possible radiation-induced increase in atherosclerotic diseases and acceleration of aging in the T-cell-related immune system, further study is necessary to confirm these findings. In the future, applying the latest gerontological study techniques to data collected from subjects exposed 45 years ago to A-bomb radiation at relatively young ages will present a new body of data relevant to the study of late radiation effects.

    The hypothesis that ionizing radiation accelerates natural aging has been under investigation at the Atomic Bomb Casualty Commission since 1959. Postmortem observations of morphologic and chemical changes, tests of functional capacity, physical tests and measurements, clinical laboratory tests, tissue changes, morbidity, and mortality have all been examined by ABCC investigators interested in this hypothesis. These studies have been beset with conceptual difficulties centered on the definition and measurement of aging. An empirical approach early led to the calculation of an index of physiologic age as a linear combination of age-related tests of various organ systems. Most studies have been negative but have not involved the large numbers that might be required to provide strong evidence for or against the hypothesis. Mortality, however, has been examined on the basis of a large sample and over the period 1950-1972 had provided no support for the hypothesis of radiation-accelerated aging. Ionizing radiation dose, of course shorten human life, but its life-shortening effect appears to be the result of specific radiation-induced disease, especially neoplasms. The hypothesis is now much less attractive than it was 10-20 years ago but still has some value in stimulating research on aging. The experience of the A-bomb survivors provides an unusual opportunity for a definitive test of the hypothesis. (auth.)

  10. Timing of mid-crustal ductile extension in the northern Snake Range metamorphic core complex, Nevada: Evidence from U/Pb zircon ages

    Metamorphic core complexes (Mccs) within the western U.S. record a history of Cenozoic ductile and brittle extensional deformation, metamorphism, and magmatism, and exhumation within the footwall of high-angle Basin and Range normal faults. Documenting these histories within Mccs have been topics of research for over 40 years, yet there remains disagreement about: 1) whether the detachment fault formed and moved at low angles or initiated at high angles and rotated to a low angle; 2) whether brittle and ductile extensional deformation were linked in space and time; and 3) the temporal relationship of both modes of extension to the development of the detachment fault. The northern Snake Range metamorphic core complex (NSR), Nevada has been central to this debate. To address these issues, we report new U/Pb dates from zircon in deformed and undeformed rhyolite dikes emplaced into ductilely thinned and horizontally stretched lower plate rocks that provide tight bounds on the timing of ductile extension at between 38.2 ± 0.3 Ma and 22.50 ± 0.36 Ma. The maximum age constraint is from the Northern dike swarm (NDS), which was emplaced in the northwest part of the range pre- to syn-tectonic with ductile extension. The minimum age constraint is from the Silver Creek dike swarm (SDS) that was emplaced in the southern part of the range post ductile extensional deformation. Our field observations, petrography, and U/Pb zircon ages on the dikes combined with published data on the geology and kinematics of extension, moderate and low temperature thermochronology on lower plate rocks, and age and faulting histories of Cenozoic sedimentary basins adjacent to the NSR are interpreted as recording an episode of localized upper crustal brittle extension during the Eocene that drove upward ductile extensional flow of hot middle crustal rocks from beneath the NSR detachment soon after, or simultaneous with, emplacement of the NDS. Exhumation of the lower plate continued in a rolling

    For the first time, a 15-year-old boy was found to have a slight degree of proteinuria and microscopic hematuria during annual school urinalysis screening. His kidney function had already severely deteriorated. A kidney biopsy revealed tubulointerstitial nephritis (TIN) with diffuse inflammatory cell infiltration. His medical records showed his serum creatinine level to be 0.98 mg/dL two years ago, which was abnormally high considering his age. Although the etiology of slowly progressive TIN was unclear, glucocorticoid and immunosuppressant therapy improved his kidney function. This case report suggests that all doctors should recognize the reference range for the serum creatinine level in teenagers.

    Type 2 diabetes is known to cause endothelial activation resulting in the secretion of von Willebrand factor (VWF). We have shown that levels of VWF in a glycoprotein Ib-binding conformation are increased in specific clinical settings. The aim of the current study is to investigate whether active VWF levels increase during aging and the development of diabetes within the population of patients suffering from type 2 diabetes. Patients and controls were divided into two groups based on age: older and younger than 60 years of age. VWF antigen, VWF propeptide, VWF activation factor and total active VWF were measured. Patients older than 60 years of age had increased levels of total active VWF, VWF activation factor and VWF propeptide compared to younger patients and controls. All measured VWF parameters were associated with age in diabetic patients. Total active VWF and VWF propeptide correlated with the period of being diagnosed with diabetes. Regression analyses showed that especially the VWF activation factor was strongly associated with diabetes in patients older than 60 years of age. In conclusion, we found that the conformation of VWF could be involved in the disease process of diabetes and that the VWF in a glycoprotein Ib-binding conformation could play a role as risk marker during the development of diabetes in combination with an increase in age. Our study shows that the active quality of VWF was more important than the quantity.

    To characterize the clinical, virological, and immunological status at presentation as well as the outcome of patients diagnosed with HIV above the age of 50. A retrospective study of 418 patients newly diagnosed with HIV in 1 Israeli center, between the years 2004 and 2013. Patients with new HIV diagnosis ≥ 50 years of age defined as "older' and < 50 defined as "younger.' Patients were evaluated every 1 to 3 months (mean follow-up 53 ± 33 months). Patients with < 2 CD4/viral-load measurements or with < 1 year of follow-up were excluded. Time of HIV infection was estimated by HIV sequence ambiguity assay. Ambiguity index ≤ 0.43 indicated recent (≤ 1 year) HIV infection. Eighty nine (21%) patients were diagnosed with HIV at an older age. Those older patients presented with significant lower CD4 cell counts and higher viral-load compared with the younger patients. At the end of the study, the older patients had higher mortality rate (21% vs 3.5%; P < 0.001) and lower CD4 cell counts (381 ± 228 vs 483 ± 26 cells/μL; P < 0.001) compared with the younger patients. This difference was also observed between older and younger patients with similar CD4 cell counts and viral load at the time of HIV diagnosis and among patients with a recent (≤ 1 year) HIV infection. One-fifth of HIV patients are diagnosed at older age (≥ 50 years). Those older patients have less favorable outcome compared with the younger patients. This point to the need of educational and screening programs within older populations and for a closer follow-up of older HIV patients.

    Although range of motion (ROM) is considered as an important factor for good outcome after total knee arthroplasty (TKA), the association of the degree of ROM with functional outcome and patient satisfaction is debated. We, therefore, investigated whether increased ROM would affect functional outcome and patient satisfaction after TKA in Asian patients. We reviewed 630 patients who underwent primary TKA with minimum 2-year follow-up. Clinical outcomes were evaluated by Knee Society (KS) score, Western Ontario and McMaster Universities osteoarthritis index, and high-flexion knee score. Patient satisfaction was evaluated using a validated questionnaire. The association of ROM and change in ROM (cROM) with clinical outcomes and satisfaction were analyzed using partial correlation analysis and multiple median regression analysis. All functional scores showed significant correlation with postoperative ROM (r = 0.129, P = .001 in Knee Society score; r = -0.101, P = .012 in Western Ontario and McMaster Universities osteoarthritis index; r = 0.183, P satisfaction (r = 0.192, P = .005). Postoperative ROM and cROM were revealed as predisposing factors affecting function outcome using multivariable regression analysis. cROM was found as a predisposing factor affecting satisfaction. Based on the results of this study, ROM positively associated with functional outcome and cROM positively associated with patient satisfaction after TKA. These findings suggest that increased ROM after TKA is an important factor for functional outcome and satisfaction in Asian patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    One percent of falls in over-75 years old cause hip fracture (HF). Protein-energy malnutrition (PEM) is associated with falls and fracture. PEM screening and perioperative nutritional management are recommended by the European Society of Parenteral and Enteral Nutrition, yet data on nutritional status in elderly HF patients are sparse. The Mini Nutritional Assessment (MNA) score is presently the most effective screening tool for PEM in over-75 years old. The principal objective of the present study was to determine the prevalence on MNA of PEM in patients aged over 75 years admitted for HF. Secondary objectives were to identify factors associated with PEM and its role as a factor of evolution. A prospective observational epidemiological study included 50 patients aged over 75 years admitted for HF in an 8-bed orthopedic surgery department with a geriatric follow-up unit. PEM was defined by MNApatients was 86.1 years (range, 77-94 years). Prevalence of PEM was 28%; a further 58% of patients were at risk for PEM. PEM was associated with elevated CIRS-G (Ppatients aged over 75 years, supporting longer hospital stay. MNA is a diagnostic gold standard, not to be replaced by albuminemia or body-mass index in this perioperative clinical situation. Given the present economic stakes relating to geriatric trauma patients' hospital stay, it is essential to prevent, diagnose and treat PEM in elderly subjects. Level IV; prospective cohort study.

    Full Text Available OBJECTIVE: To retrospectively evaluate the results from patients who underwent arthroscopic treatment for rotator cuff injuries, among those aged over 65 years, observing integrity, function and strength.METHODS: Thirty-five shoulders were operated between July 2005 and July 2010, and 28 shoulders were re-evaluated regarding elevation strength and external rotation, using a digital dynamometer. Integrity was evaluated by means of ultrasound examinations. The patients, whose mean age was 70.54 years (ranging from 65 to 82 years, were followed up for a minimum of 26 months and mean of 51.18 months (ranging from 26 to 82 months. To evaluate function, the UCLA score, the Simple Shoulder Test (SST and a visual analog scale (VAS for pain were used.RESULTS: In analyzing the ultrasound scans, it was observed that the integrity of the rotator cuff was maintained in 75% of the cases at the end of the follow-up, along with the improvement in the UCLA score, which evolved from 17.46 to 32.39, i.e. excellent and good results in 89.28%. The mean SST and VAS indices were 9.86 and 1.5 respectively.CONCLUSION: Arthroscopic surgery to repair rotator cuff injuries in patients over the age of 65 years leads to improved function and pain relief, with maintenance of the integrity of the repair. The data on muscle strength were inconclusive.

    2005-01-01

    In order to identify possible age-dependent dielectric properties of brain and eye tissues in the frequency range of 400 MHz to 18 GHz, measurements on bovine grey and white matter as well as on cornea, lens (cortical) and the vitreous body were performed using a commercially available open-ended coaxial probe and a computer-controlled vector network analyser. Freshly excised tissues of 52 animals of two age groups (42 adult animals, i.e. 16-24 month old and 10 young animals, i.e. 4-6 month old calves) were examined within 8 min (brain tissue) and 15 min (eye tissue), respectively, of the animals' death. Tissue temperatures for the measurements were 32 ± 1 0 C and 25 ± 1 0 C for brain and eye tissues, respectively. Statistical analysis of the measured data revealed significant differences in the dielectric properties of white matter and cortical lens tissue between the adult and the young group. In the case of white matter the mean values of conductivity and permittivity of young tissue were 15%-22% and 12%-15%, respectively, higher compared to the adult tissue in the considered frequency range. Similarly, young cortical lens tissue was 25%-76% higher in conductivity and 27%-39% higher in permittivity than adult cortical lens tissue

    Several recent reports have linked the use of dopamine agonists (DAs) to a variety of compulsive behaviors in patients with Parkinson's disease (PD). These inappropriate behaviors may include pathological gambling, compulsive shopping, and hypersexuality. To report the case of a patient with increased range of sexual behavior after use of pramipexole, a DA. A 67-year-old man with a 7-year diagnosis of PD treated with levodopa and pramipexole presented with a dramatic change in sexual behavior after an increase in DA dose. The patient, who historically was a very shy and conservative person, started to present increased frequency of sexual intercourse with his wife, during which he began speaking obscenities with an extreme preference for anal intercourse, preferences never requested before. After pramipexole was withdrawn, complete remission was observed with return to his usual sexual behavior. Hypersexuality and paraphilias are complications not uncommonly found in patients with PD under dopaminergic treatment. Further studies are needed for the understanding of this complex complication, and particularly the most prevalent relationship between pathological hypersexuality and use of DAs.

    Since a majority of old aged patients have the troublesome complications and their physical or mental emaciation is clearly appeared, it is necessary for them to adopt a new treatment method which was considered about thier such conditions. The crude survival rate of old aged, over 71, patients suffered from carcinoma of the uterine cervix were 63.6% (7/11) for stage 1, 60% (36/60) for stage 2, 50% (53/106) for stage 3 and 28.6% (8/28) for stage 4. About 20% of patients in each stages were suffered from the complications. We considered the treatment method for the old aged patients such as follows: the radiation dose must be reduced 10% for 71 to 75 year old and 20% for 76 to 80 year old. In the case of over 81 year old, an intracavitary irradiation is only applied for the palliative aim at the out patient clinic. (author)

    First stimulant exposure at a young age is thus associated with lower baseline levels of GABA+ and increased responsivity in adulthood. This effect could not be found in patients that started treatment at an adult age. Hence, while adult stimulant treatment seems to exert no major effects on GABA+ levels in the mPFC, MPH may induce long-lasting alterations in the adult mPFC GABAergic system when treatment was started at a young age.

    As life expectancies increase, nurses will care for more individuals with chronic conditions, one of which is chronic renal disease. Increasing diversity and complexity of older adult healthcare needs signals a need to reconceptualize perceptions of successful aging. By emphasizing health promotion and adaptation, successful aging is possible for those with chronic renal disease. This article provides an overview of theory-based strategies for fostering successful aging in the patient with chronic renal disease.

    Purpose: To profile cancer patients aged 80 and older undergoing radiotherapy and to study the tumor response and side effects of therapy. Methods and Materials: We retrospectively analyzed the records of patients aged 80 and older who received radiation therapy at James A. Haley Veterans Hospital and H. Lee Moffitt Cancer Center between 1988 and 1995. A total of 203 patients aged 80-94 received radiotherapy during this period. Treatment sites included head and neck [50], breast [16], chest [37], pelvis [53], and miscellaneous [39]. Age, treatment site, field size, total dose, response to treatment, treatment interruptions, incidence and severity of weight loss, myelosuppression, diarrhea, mucositis, dermatitis, and follow-up status are assessed using our departmental records and hospital tumor registry. Results: Of 191 patients evaluated, 179 (94%) completed the treatment without serious complications. A total of 195 sites were irradiated. Twelve patients (6%) required interruption of the treatment. Therapeutic responses were seen in 86 out of 112 patients (77%) treated with curative intent (with 67% complete response) and in 67 out of 83 patients (81%) treated with palliative intent. The causes of treatment interruptions included weight loss from diarrhea, dysphagia, and progressive disease. Treatment interruptions were more likely in patients treated with large treatment fields. In patients treated for upper aero-digestive tract cancer, Grade 3 and 4 mucositis was noted in 20 and 2% of patients, respectively. Grade 1 and 2 enteritis was noted in 43% of patients treated for pelvic malignancies. Grade 3 dermatitis was noted only in 2% of patients. Conclusion: Radiotherapy is highly effective and well tolerated by the oldest old. Age is not a contraindication to aggressive radiotherapy

    Full Text Available BACKGROUND Hospital overcrowding (HO profoundly affects the whole hospital system, reducing productivity and efficiency. The aging population and the increased prevalence of chronic-degenerative diseases, susceptible to acute exacerbations, make the elderly as frequent users of the emergency room (ER. There is a general agreement that the current disease-oriented and episodic model of care does not adequately cope with the complex needs of older patients. Hospital admission and discharge do not sufficiently link with primary care and other community resources, such as long-term care facilities and outpatient clinics. AIM OF THE STUDY To evaluate, using a simple dedicated software, the activity data of nine hospitals of Local Health Authority of Bologna (Italy (ER accesses, hospital admissions, average length of stay – LOS and the impact of a patient and bed management net in which managers, doctors and nurses share their operational skills to improve patient flow in medical and geriatric wards. RESULTS Data show that 24% ER accesses concern people > 75 years old; 51% admissions concern people > 75 years old; half of these admissions are from ER frequent users (FU = ≥ 3 ER accesses/ year. Only 15% admissions of younger people are from ER frequent users. Each of > 75 years old frequent users produces an average of 2 admissions/year. At the end of the first year of this experience, ER accesses and admissions rose more than 8%. In our model of bed-management (patient and bed management net-software matching hospital capacity with admission, escalation measures LOS was shortened by an average 0.5-1 day to a range from 0,5 to 1 day. DISCUSSION HO is due to mismanagement of chronic diseases (CD. Further actions are needed in primary health care to avoid unscheduled hospital due to CD. Applications for admission to hospital should be administered in the real context of the needs, developing both measures to face the contingent situation (setting

    Issue addressed The present study investigated the association between diet quality, measured using the Australian Recommended Food Score (ARFS), and 6-year risk of becoming overweight or obese in mid-age women from the Australian Longitudinal Study of Women's Health (ALSWH). Methods Women (n=1107) aged 47.6-55.8 years who were a healthy weight (body mass index (BMI) between ≤18.5 and healthy weight range and those who became overweight or obese at follow-up was 35.3±8.1 and 34.3±8.8, respectively. There was no relationship between baseline ARFS and risk of becoming overweight or obese over 6 years. Women who were smokers were more likely to become overweight or obese (odds ratio 1.5; 95% confidence interval 1.11-2.09; P=0.008). Conclusions Poor diet quality was common among mid-age women of a healthy weight in the ALSWH. Higher diet quality was not associated with the risk of overweight or obesity after 6 years, yet smoking status was. So what? Better diet quality alone will not achieve maintenance of a healthy weight, but should be encouraged to improve other health outcomes.

    Intake of trans-fatty acids (TFA), especially industrially produced TFA (I-TFA), has been associated with the risk of CHD through influence on serum lipid levels. Other causal pathways remain less investigated. In the present cross-sectional study of middle-aged men representing a broad range...... of BMI, the association between intake of TFA, I-TFA and ruminant TFA (R-TFA) and obesity-associated risk markers of CHD was assessed. The study comprised 393 Danish men (median age 49 years) with a median BMI of 28·4 kg/m2. Intake of TFA was estimated based on 7 d dietary records, whereas outcomes...... pressure and insulin homeostasis. Among middle-aged men with a generally low intake of TFA, neither I-TFA nor R-TFA was significantly related to obesity-associated risk markers of CHD. The decreased average intake of I-TFA in Denmark since 1995 is suggested to effectively prevent occurrence of the adverse...

    Chronic heart failure (CHF), a major public health problem worldwide, seriously limits health-related quality of life (HRQOL). How to evaluate HRQOL in older patients with CHF remains a problem. To evaluate the reliability and validity of the Chinese version of the Medical Outcomes Study Short Form version 2 (SF-36v2) in CHF patients. From September 2012 to June 2014, we assessed QOL using the SF-36v2 in 171 aging participants with CHF in four cardiology departments. Convergent and discriminant validity, factorial validity, sensitivity among different NYHA classes and between different age groups, and reliability were determined using standard measurement methods. A total of 150 participants completed a structured questionnaire including general information and the Chinese SF-36v2; 132 questionnaires were considered valid, while 21 patients refused to take part. 25 of the 50 participants invited to complete the 2-week test-retest questionnaires returned completed questionnaires. The internal consistency reliability (Cronbach's α) of the total SF-36v2 was 0.92 (range 0.74-0.93). All hypothesized item-subscale correlations showed satisfactory convergent and discriminant validity. Sensitivity was measured in different NYHA classes and age groups. Comparison of different NYHA classes showed statistical significance, but there was no significant difference between age groups. We confirmed the SF-36v2 as a valid instrument for evaluating HRQOL Chinese CHF patients. Both reliability and validity were strongly satisfactory, but there was divergence in understanding subscales such as "social functioning" because of differing cultural background. The reliability, validity, and sensitivity of SF-36v2 in aging patients with CHF were acceptable.

    Knowledge is an essential element of treatment which allows patients to take care of themselves, to undertake every day activities and to make decisions essential from the point of view of health. A patient suffering from rheumatoid arthritis needs support, assistance from his family and from medical staff. It depends on him how much the disease will change his life and how he will cope with all the problems related to the psychological, physical and social aspects of life. Each patient should know what his disease is. If he does not receive this information from the qualified staff, he will try to find some information from different sources and then the information may be incomplete and may provoke negative reactions which will make the process of treatment more difficult. Defining the source of the patient's knowledge about his disease and the role and tasks of health education in transferring knowledge to the patient and in building his attitude to the treatment. Increasing participation of a therapeutic team in health education in order to propagate the awareness and need of prevention and physical effort for bringing back normal state of health. The subject of studies included 270 people with rheumatoid arthritis. The patients examined were treated in the Clinic of Rheumatology and Internal Diseases of the University of Wroclaw since 1st February, 2010 till 15th February, 2011. A self-made questionnaire was used for studies, aimed at obtaining basic information about patients with a diagnosed rheumatoid arthritis. Statistical calculations were made with package Statistica 9 PL. Tests on essentiality of differences were calculated with T-Student test for quantitative data and chi2 test for qualitative data. Abroad, the level of significance was a value of 0.05. The examined patients were divided into 2 groups according to gender. These groups were similar in respect of age, place of residence, professional activity, working time and co-existing diseases

    Advancing age is a well-known risk factor for Parkinson's disease (PD). With population ageing it is expected that the total number of patients with PD onset at oldage increases. Information on the motor but particularly on non-motor phenotype of this late-onset population is lacking. We recruited 24 patients with PD onset at or over 75 years. Each patient was matched with 1 control patient with PD onset between the ages of 40 and 65 and matched for disease duration. Both groups were assessed with the UPDRS, the Non-motor symptoms scale (NMSS) and other scales to assess non-motor symptoms. Groups were compared with conditional logistic regression analysis. Old-age onset PD was, on average, 80 years at the time of PD onset while middle-age onset were 59. Disease duration was approximately 5 years in both groups. While no difference was observed in the total UPDRS-III scores, old-age onset PD was associated with higher axial symptoms (7.42 vs. 4.63, p = 0.011) and a higher frequency of dementia (7/24 vs. 0/24, p = 0.009). While no difference in the total number of non-motor symptoms was observed (6.79 vs. 6.22, p = 0.310), old-age onset patients had a higher prevalence of gastrointestinal symptoms (20/24 vs. 12/24, p = 0.037). For the same disease duration, older age onset is associated with worse axial motor dysfunction and dementia in PD patients. Beside gastrointestinal symptoms, non-motor symptoms are not associated with age.

    Previous studies have reported that older cancer patients experience lower psychological distress than younger patients, but most prior studies do not differentiate between age groups within the 'older' category. The aim of this study was to assess the intensity of the symptoms of depression, anxiety, and somatic symptoms among different age groups of older cancer patients. Participants were composed of 321 cancer patients 60 years and older, who were divided into three age groups: 60-69, 70-79, and 80+ years. The participants answered the Brief Symptom Inventory-18, which included subscales for depression, anxiety, and somatic symptoms and the cancer-related problem list, in addition to providing personal and cancer-related details. Depressive, anxiety, and somatic symptoms and cancer-related problems were lowest in the 70-79 years age group and highest in the 80+ years age group. Comparisons between pairs of groups showed significant differences between each of the groups in Brief Symptom Inventory total scores and between the 80+ years age group and the other two groups in regard to depressive symptoms and cancer-related problems. Differences, related to anxiety and somatic symptoms, were significant for the 70-79 year olds, in comparison with the youngest and oldest groups. Intensity of symptoms was explained by older age, higher number of cancer-related problems, female gender, and lower income. Nonlinear relations exist between age and psychological symptoms, which is in line with the postponement of age-related health and functional decline in the modern era. These results suggest that the study of psychological reactions to cancer should examine differences between age groups among older cancer patients. Copyright © 2013 John Wiley & Sons, Ltd.

    A variety of factors have been implicated in the pathogenesis of age-related macular degeneration (ARMD), and oxidative stress plays an important role in the onset and progression of the disease. Breath ethane is now considered a specific and non-invasive test for determining and monitoring the trend of lipid peroxidation and free radical-induced damage in vivo. This test provides an index of the patients' overall oxidative stress level. We evaluated the breath ethane concentration in exhaled air in patients with advanced ARMD. In this study, we enrolled 13 patients with advanced ARMD and a control group, and a breath analysis was carried out by gas chromatography. The mean ethane level in the ARMD patients was 0.82 ± 0.93 nmol/l (range: 0.01-2.7 nmol/l) and the mean ethane value in the control group was 0.12 ± 0.02 nmol/l (range: 0.08-0.16 nmol/l). The difference between the values of the 2 groups was statistically significant (p ethane levels are higher in most patients with ARMD. The breath ethane test could thus be a useful method for evaluating the level of oxidative stress in patients with ARMD. To our knowledge, there are no data on this type of analysis applied to ARMD.

    Introduction: The aim of this study is to evaluate the incidence of peritrochanteric high T2 signal (peritrochanteric edema, peritendinitis) on routine MR imaging studies and to determine whether reporting peritrochanteric edema is always clinically relevant depending on the age and gender of the patients. Materials and methods: We evaluated 79 consecutive bilateral hip MR images performed in our department between January 2006 and December 2006 (57 female, 22 male patients, mean age 49 years). Each study was evaluated for areas of T2 hyperintensity representing edema around the greater trochanter. Patients with a known fracture, tumor, history of radiation therapy, history of hip surgery and prothesis were excluded from the study. Patients with signal intensity alterations within the thickened gluteus medius/minimus tendons (tendinitis) or peritrochanteric bursal fluid accumulation (bursitis) were also excluded. All patients were scanned with our routine MR imaging protocol for hip imaging. Results: In 55 of the 79 patients (70%) peritrochanteric edema was detected on MR images and 52 of these 55 patients (95%) had these changes on both hips. The median age was 56 years for the patients with peritrochanteric edema and 35.5 years for the patients without peritrochanteric edema. There was statistical significance between the median ages of the patients and a significant increased risk of peritrochanteric edema was found over 40 years of age. There was no significant difference between male and female patients. Conclusion: Bilateral peritrochanteric high T2 signal may be a part of the degeneration process and we suggest that it may not be necessarily reported if the clinical findings do not support greater trochanteric pain syndrome.

    The authors studied the histological alterations and the expression of matrix metalloproteinase (MMP)-1 and MMP-3 in disc specimens of patients who had undergone operations for lumbar disc herniation. Forty-three lumbar disc specimens were evaluated histopathologically for degenerative changes and immunohistochemical expression of MMP-1 and MMP-3. The observed degenerative changes provided a degenerative score that was applied in each patient. Sections of disc immunostained for MMP-1 and MMP-3 were evaluated semiquantitatively. Patients were categorized in 3 age groups: 60 years of age. The expression of MMP-1 and MMP-3 were correlated to patient's age, degenerative score, and grade of lumbar disc herniation. There was no statistically significant difference in the degenerative score between the age groups. Degenerative changes were more pronounced in greater grades of herniation (p correlation between MMP-1 and MMP-3 expression and both degenerative score and herniation grade. For the group of patients 30-60 years of age, there was no significant difference between MMP-1 expression and degenerative score, but the correlation between MMP-1 expression and grade of herniation was significant. There was a significant correlation between MMP-3 expression and both degenerative score and herniation grade. Regarding the patients > 60 years of age, there was a significant correlation between MMP-1 and MMP-3 expression and both degenerative score and herniation grade. There was a significantly lower expression of both MMP-1 and MMP-3 in the group correlation was found in MMP-1 and MMP-3 expression between the groups of patients who were 30-60 and > 60 years of age. Interestingly, in age groups > 30 years, there were no statistically significant differences between the expression of MMP-1 and MMP-3, whereas in patients correlated to the age of the patients and the grade of herniation. An important finding in this study is the differential expression of MMP-1 and MMP-3

    Full Text Available Background: Ninety percent of all people sometimes during their lives experience low back pain, and 30-40% develops radicular leg pain with the sciatica characteristics. Although for clinical diagnosis of lumbar disc herniation (LDH straight leg raising (SLR test in 85-90% of cases indicates LDH, but in our practice with LDH patients this test is frequently negative despite radicular leg pain due to LDH. Hence, we decided to evaluate this test in LDH in different age groups. Materials and Methods: All patients with leg pain referring to neurosurgery clinic were enrolled. Those with a history of pain other than sciatica excluded and SLR test and magnetic resonance imaging (MRI of the lumbosacral spine performed. The patients with negative MRI findings excluded and finally 269 patients with true sciatica and positive MRI were included. SLR tests were performed for different age groups. Results: Of 269 patients, 167 were male. The age range was 16-80 years. The most involved levels were L5-S1 (47% and L4-L5 (42%, respectively. The rate of positive SLR result, which was 100%, 87% and 82% for 10-19, 20-29 and 30-39 years age group respectively. With an increment of age, the rate of positive test regularly declined . The chance of positive SLR in men is 1.3 times the women (odds ratio [OR] 2.4; 95% confidence interval [CI] = 1.265-4.557; P = 0.007. Increasing the age has suppression effect in positivity of SLR so that for each 1-year the chance of SLR become 0.27 times less to become positive and this is also statically meaningful (OR = 0.271;95% CI = 0.188-0.391; P,0.001. The chance of positive SLR for patients under 60 is 5.4 folds more than patients above 60 years old (OR = 5.4; 95% CI = 4-8.3; P, 0.001. Conclusion: Age, sex (male, and disk level had statistically the effect on SLR positive test.

    The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest reasonable guideline of breast imaging in breast cancer patients under 30 years of age in whom breast cancer shows different clinicopathologic characteristics compared with breast cancer in older women. Authors reviewed medical records of 27 patients under 30 years of age with pathologically-proven breast cancer. Age, family history, physical examination findings, indications for breast sonography were reviewed. Cases in whom breast cancer lesion is detectable and cases in whom not detectable using mammography or breast sonography were reviewed. And then, authors evaluated the usefulness of each method and reasons for nonvisualization of lesion on mammography. Among 27 patients, 25 patients had palpable breast mass as indication of mammography and breast sonography. Cancer lesions were detectable in 16 of 25 patients (64%) on mammography and 24 of 25 patients (96%) on breast ultrasonography. Reasons for nonvisualization of cancer lesions on mammography were dense breast with nodular parenchyma pattern and minimal breast change of ductal carcinoma in situ. In breast cancer patients under 30 years of age who have palpable breast mass as a initial, and main clinical problem, breast ultrasonography is superior to mammography in detecting and diagnosing breast cancer. We suggest that guidelines can avoid unnecessary mammography in these patients.

    The purpose of this study was to compare mammography and breast sonography in detection of breast cancer and to suggest reasonable guideline of breast imaging in breast cancer patients under 30 years of age in whom breast cancer shows different clinicopathologic characteristics compared with breast cancer in older women. Authors reviewed medical records of 27 patients under 30 years of age with pathologically-proven breast cancer. Age, family history, physical examination findings, indications for breast sonography were reviewed. Cases in whom breast cancer lesion is detectable and cases in whom not detectable using mammography or breast sonography were reviewed. And then, authors evaluated the usefulness of each method and reasons for nonvisualization of lesion on mammography. Among 27 patients, 25 patients had palpable breast mass as indication of mammography and breast sonography. Cancer lesions were detectable in 16 of 25 patients (64%) on mammography and 24 of 25 patients (96%) on breast ultrasonography. Reasons for nonvisualization of cancer lesions on mammography were dense breast with nodular parenchyma pattern and minimal breast change of ductal carcinoma in situ. In breast cancer patients under 30 years of age who have palpable breast mass as a initial, and main clinical problem, breast ultrasonography is superior to mammography in detecting and diagnosing breast cancer. We suggest that guidelines can avoid unnecessary mammography in these patients

    Full Text Available Aim. To study the ranges of low density lipoprotein (LDL cholesterol depending on the age and gender of patients with familial hypercholesterolemia (FHC by an example of a sample of patients living in the Republic of Karelia.Material and methods. Parameters of lipid spectrum of 219 patients (aged 52.5±1.7 years; males 38.3% with heterozygous FHC were studied before the start of statin therapy. Definite FHC was diagnosed in 102 patients. Lipid profile was estimated by enzymatic calorimetric method. The diagnosis of FHC was established according to the criteria of The Dutch Lipid Clinic Network.  Genetic analysis was performed in 102 patients (46.6%; pathogenic mutation in the LDL receptor was identified in 21 patients. The control group consisted of 539 people with the excluded diagnosis of FHC (aged 46.8±0.8 years; males 53.8%.Results. We determined the level of LDL cholesterol (LDLC associated with increased frequency of mutations of the LDL receptor in patients with definite FHC; mutation frequency was 3 times higher when LDLC level was more than 6.5 mmol/L. We revealed the following characteristic intervals of the LDLC levels in patients with a definite FHC: up to 20 years old – 4.8-6.2 mmol/l; in patients of 20-29 years old – 5.9-8.2 mmol/l; in the age range of 30-39 years the upper value of the LDLC levels reached 9.6 mmol/l; in individuals of 40-49 years old a stabilization, "plateau", was observed – LDLC level did not differ significantly compared to the previous decade, and was 5.4-9.0 mmol/l. In the age range  of 50-59 years the upper LDLC level was up to 11.4 mmol/l. Similar indicators were identified in patients aged 60-69 years. Patients older than 70 years with a definite FHC an upper level of LDLC was higher and reached 12.5 mmol/l. Tendency to increase in the characteristic values of LDLC with age was observed both in men and in women. Specific age-related trends  for men (an increase from a plateau by the age of 50

    Aging and malnutrition are known to influence immune functions. The aim of this study was to investigate the relationship of aging and malnutrition to innate immune functions in tube-fed bedridden patients. A cross-sectional survey was performed in 71 tube-fed bedridden patients aged 50-95 years (mean age±SD, 80.2±8.5 years) with serum albumin concentrations between 2.5 and 3.5 g/dL. We evaluated associations of age and nutritional variables with natural-killer cell activity, neutrophilphagocytic activity, and neutrophil-sterilizing activity. Nutritional variables included body mass index, weightadjusted energy intake, total lymphocyte count, and serum concentrations of albumin, transferrin, prealbumin, total cholesterol, C-reactive protein, and zinc. Natural-killer cell activity, neutrophil-phagocytic activity, and neutrophil-sterilizing activity were normal or increased in 67 (94%), 63 (89%), and 69 (97%) patients, respectively. Multiple linear regression analysis with a backward elimination method showed that natural-killer cell activity correlated negatively with aging and lymphocyte counts (pbedridden patients with hypo-albuminemia, natural-killer cell activity may be associated with aging, body mass index, transferrin, and lymphocyte counts.

    To analyze age-related pathologic hobbies in patients with schizophrenia spectrum disorders. Forty-three inpatients, aged from 4 to 16 years, and 31 patients, aged from 18 to 65 years, were studied. Clinical/psychopathological analysis, psychological experiment and clinical statistics were used. Pathological hobbies substantially differed depending on the age (3-6, 7-15 and 18-65 years). In preschool age, hobbies were immature and infantile, arose autochthonously, their course was relatively stable and they had limited maladaptive effects. In junior school/teenager age, hobbies were more distinct and were associated with more diverse and mature realization patterns. Their origin was more depended on environmental factors, the course was persistent or attack-like with more pronounced and steady maladaptive effects. In some cases, there was a trend to pathological hobby progression. Abnormal hobbies in patients of mature age were the most diverse in their subjects and forms of realization as well as in their clinical variants and dynamic types. In the group of mature patients with schizophrenic spectrum disorders, there was a significantly higher percentage of psychotic forms of pathological hobbies.

    High glucose level in diabetic patients may lead to advanced glycation end product (AGE) modified proteins. This study investigated AGE modified proteins in tears and compared their levels in diabetic patients (DM) with non-diabetic controls (CTL). Basal tears were collected from DM with (DR) or without (DNR) retinopathy and CTL. Total AGE modified proteins were detected quantitatively by a dot immunobinding assay. The AGE modified proteins were separated in 1D- and 2D-SDS gels and detected by western-blotting. The individual AGE modified proteins were also compared between groups using densitometry. Compared with the CTL group, tear concentrations of AGE modified proteins were significantly elevated in DR and DNR groups. The concentration of AGE modified proteins in diabetic tears were positively correlated with AGE modified hemoglobin (HbA1c) and postprandial blood glucose level (PBG). Western blotting of AGE modified proteins from 1D-SDS gels showed several bands, the major one at around 60 kDa. The intensities of AGE modified protein bands were higher in DM tears than in CTL tears. Western blotting from 2D-SDS gels showed a strongly stained horizontal strip, which corresponded to the major band in 1D-SDS gels. Most of the other AGE modified protein species were within molecular weight of 30-60 kDa, PI 5.2-7.0. Densitometry analysis demonstrated several AGE modified proteins were elevated in DR or DNR tears. Total and some individual AGE modified proteins were elevated in DM tears. AGE modified proteins in tears may be used as biomarkers to diagnose diabetes and/or diabetic retinopathy.

    OBJECTIVE It is generally accepted that cerebrospinal fluid shunts fail most frequently in the first years of life. The purpose of this study was to describe the risk of shunt failure for a given patient age in a well-defined cohort with shunted hydrocephalus due to myelomeningocele (MMC). METHODS The authors analyzed data from their institutional spina bifida research database including all patients with MMC and shunted hydrocephalus. For the entire population, the number of shunt revisions in each year of life was determined. Then the number of patients at risk for shunt revision during each year of life was calculated, thus enabling them to calculate the rate of shunt revision per patient in each year of life. In this way, the timing of all shunt revision operations for the entire clinic population and the likelihood of having a shunt revision during each year of life were calculated. RESULTS A total of 655 patients were enrolled in the spina bifida research database, 519 of whom had a diagnosis of MMC and whose mean age was 17.48 ± 11.7 years (median 16 years, range 0-63 years). Four hundred seventeen patients had had a CSF shunt for the treatment of hydrocephalus and thus are included in this analysis. There were 94 shunt revisions in the 1st year of life, which represents a rate of 0.23 revisions per patient in that year. The rate of shunt revision per patient-year initially decreased as age increased, except for an increase in revision frequency in the early teen years. Shunt revisions continued to occur as late as 43 years of age. CONCLUSIONS These data substantiate the idea that shunt revision surgeries in patients with MMC are most common in the 1st year of life and decrease thereafter, except for an increase in the early teen years. A persistent risk of shunt failure was observed well into adult life. These findings underscore the importance of routine follow-up of all MMC patients with shunted hydrocephalus and will aid in counseling patients and

    Objective: To investigate the change of serum insulin level in essential hypertension patients and its relationship with age and sex. Methods: The levels of serum insulin were determined with radioimmunoassay in 980 essential hypertension patients and 120 controls. Results: The levels of serum insulin in the essential hypertension patients were significantly higher than those in the controls (t=4.280, P<0.01). However, there were no significant differences among the levels in different sex and age groups. The same held true for women before and after menopause as well as different stages of hypertension. Conclusion: The average serum insulin level in EH patients was significantly higher than the level in controls, and had positive correlation to mean arterial pressure. But no significant differences were found among different sex and age groups, so serum insulin could be a new independent risk factor of essential hypertension

    Cobalamin deficiency is responsible for hematological, neurological, neurocognitive, and neuropsychiatric impairments and is a risk factor for cardiovascular diseases, particularly in the elderly people. In order to determine B12 status in old inpatients, a total number of 14,904 hospitalized patients in whom B12 measurements were performed in five hospitals in the Paris metropolitan area were included from January 1, 2011 to December 31, 2011. The aims of the study were to determine whether age had an impact on B12 and folate deficiencies and to evaluate correlations between B12 and biological parameters-folate, hemoglobin, mean cell volume, homocystein (tHcy)-and age. Patients were aged 70.3±19.5 years. Low B12 concentration ( 17 µmol/L), 20.4% had low folate concentration (folate 17 µmol/L), and 4.7% of patients were both functional B12 and folate deficient. The B12 or folate deficient patients had lower mean cell volume level than nondeficient patients. Increase in mean cell volume and tHcy concentrations with age and decrease in B12, folate, and hemoglobin levels with age were observed. Frequency of functional B12 deficiency was 9.6% in patients aged 30-60 years and 14.2% in patients over 90 years. Frequency of functional folate deficiency was 9.5% in 30-60 years and 12.1% in >90 years. In inpatients, functional B12 deficiency and functional folate deficiency increase with age and are not associated with anemia or macrocytosis. False vitamin B deficiencies are frequent. © The Author 2014. Published by Oxford University Press on behalf of The Gerontological Society of America. All rights reserved.

    Background. This qualitative study aims to gain insight into the perceptions and experiences of older patients with regard to sharing health care decisions with their general practitioners. Patients and Methods. Thirty-four general practice patients (≥70 years) were asked about their preferences and experiences concerning shared decision making with their doctors using qualitative semistructured interviews. All interviews were analysed according to principles of content analysis. The resulting categories were then arranged into a classification grid to develop a typology of preferences for participating in decision-making processes. Results. Older patients generally preferred to make decisions concerning everyday life rather than medical decisions, which they preferred to leave to their doctors. We characterised eight different patient types based on four interdependent positions (self-determination, adherence, information seeking, and trust). Experiences of a good doctor-patient relationship were associated with trust, reliance on the doctor for information and decision making, and adherence. Conclusion. Owing to the varied patient decision-making types, it is not easy for doctors to anticipate the desired level of patient involvement. However, the decision matter and the self-determination of patients provide good starting points in preparing the ground for shared decision making. A good relationship with the doctor facilitates satisfying decision-making experiences. PMID:23691317

    To compare efficacy and safety of various doses of tofacitinib, an oral Janus kinase inhibitor, with placebo in patients with active ankylosing spondylitis (AS, radiographic axial spondyloarthritis). In this 16-week (12-week treatment, 4-week washout), phase II, multicentre, dose-ranging trial, adult patients with active AS were randomised (N=51, 52, 52, 52, respectively) to placebo or tofacitinib 2, 5 or 10 mg twice daily. The primary efficacy endpoint was Assessment of SpondyloArthritis International Society 20% improvement (ASAS20) response rate at week 12. Secondary endpoints included objective measures of disease activity, patient-reported outcomes and MRI of sacroiliac joints and spine. Safety was monitored. Emax model analysis of the primary endpoint predicted a tofacitinib 10 mg twice daily ASAS20 response rate of 67.4%, 27.3% higher than placebo. Supportive normal approximation analysis demonstrated tofacitinib 5 mg twice daily ASAS20 response rate significantly higher than placebo (80.8% vs 41.2%; ptofacitinib 2 and 10 mg twice daily demonstrated greater response rate than placebo (51.9% and 55.8%, respectively; not significant). Secondary endpoints generally demonstrated greater improvements with tofacitinib 5 and 10 mg twice daily than placebo. Objective (including MRI) endpoints demonstrated clear dose response. Adverse events were similar across treatment groups with no unexpected safety findings. Dose-dependent laboratory outcome changes returned close to baseline by week 16. Tofacitinib 5 and 10 mg twice daily demonstrated greater clinical efficacy versus placebo in reducing signs, symptoms and objective endpoints of active AS in adult patients with a similar 12-week safety profile as reported in other indications.

Spontaneous wrist locomotor activity was measured for 7 days with actigraphy, and detrended fluctuation analysis was applied to assess correlations over a range of time scales from minutes to 24 h. For all the subjects, complex scale-invariant correlations...... scale invariance. Conversely, activity patterns at time scales between 10 and 24 h were significantly more regular than all other time scales, and this was mostly associated with age. In conclusion, scale invariance is degraded in healthy subjects at the ages of >33 year as characterized by attenuation......Motor activity in healthy young humans displays intrinsic fluctuations that are scale-invariant over a wide range of time scales (from minutes to hours). Human postmortem and animal lesion studies showed that the intact function of the suprachiasmatic nucleus (SCN) is required to maintain...

    Aging of an individual entails a progressive decline of functional reserves and loss of homeostasis that eventually lead to mortality. This process is highly individualized and is influenced by multiple genetic, epigenetic and environmental factors. This individualization and the diversity of factors influencing aging result in a significant heterogeneity among people with the same chronological age, representing a major challenge in daily oncology practice. Thus, many factors other than mere chronological age will contribute to treatment tolerance and outcome in the older patients with cancer. Clinical/comprehensive geriatric assessment can provide information on the general health status of individuals, but is far from perfect as a prognostic/predictive tool for individual patients. On the other hand, aging can also be assessed in terms of biological changes in certain tissues like the blood compartment which result from adaptive alterations due to past history of exposures, as well as intrinsic aging processes. There are major signs of 'aging' in lymphocytes (e.g. lymphocyte subset distribution, telomere length, p16INK4A expression), and also in (inflammatory) cytokine expression and gene expression patterns. These result from a combination of the above two processes, overlaying genetic predispositions which contribute significantly to the aging phenotype. These potential "aging biomarkers" might provide additional prognostic/predictive information supplementing clinical evaluation. The purpose of the current paper is to describe the most relevant potential "aging biomarkers" (markers that indicate the biological functional age of patients) which focus on the biological background, the (limited) available clinical data, and technical challenges. Despite their great potential interest, there is a need for much more (validated) clinical data before these biomarkers could be used in a routine clinical setting. This manuscript tries to provide a guideline on how

    The present study aims to develop age-dependent cutoff values in a quasi-experimental, cross-sectional diagnostic test study. One hundred and twenty (120) asymptomatic subjects (n = 100, 36♀, 18 75 years, for normative values; n = 20, 23-75 years, 15♀, for selectivity analyses) and 20 patients suffering from idiopathic neck pain (selectivity analyses, 22-71 years, 15♀) were included. Subjects performed five repetitive maximal cervical flexion/extension movements in an upright sitting position. Cervical kinematic characteristics (maximal range of motion (ROM), coefficient of variation (CV) and mean conjunct movements in rotation and flexion (CM)) were calculated from raw 3D ultrasonic data. Regression analyses were conducted to reveal associations between kinematic characteristics and age and gender and thus to determine normative values for healthy subjects. Age explains 53 % of the variance in ROM (decrease 10.2° per decade), 13 % in CV (increase 0.003 per decade) and 9 % in CM (increase 0.57° per decade). Receivers operating characteristic (ROC) analyses were conducted for differences between individual values of the kinematic characteristics and normative values to optimise cutoff values for distinguishing patients from unimpaired subjects (20 patients and 20 healthy). Cutoff values distinguished asymptomatic subjects' and chronic nonspecific neck patient's movement characteristics with sufficient quality (sensitivity 70-80 %, specificity 65-70 %). By including such classifications, the present findings expand actual research stating an age-related decrease in kinematic behaviour only using categorising span widths across decades. Future study is warranted to reveal our results' potential applicability for intervention onset decision making for idiopathic neck pain patients.

    New Zealand currently defines the adolescent and young adult (AYA) group for cancer services as young people 12-24 years of age, while other countries favour a designation of 15-29 years. This study was undertaken to compare cancer incidence and survival among 25-29 year olds to New Zealand's younger AYA population and to assess survival for our 15-29 year population against international benchmarks. Diagnostic and demographic information for cancer registrations between 2000 and 2009 for 25-29 year olds was obtained from the New Zealand Cancer Registry. Incidence rates (IR) and five-year relative survival estimates were calculated according to AYA diagnostic group/sub-group, sex and prioritised ethnicity. 1,541 new primary malignant cancers were diagnosed (IR: 588 per million). Five-year relative survival was 85%, but was significantly lower for Māori and Pacific peoples (both 77%) compared to non-Māori/non-Pacific peoples (88%). In the overall 15-29 year AYA cohort, disease-specific outcomes for bone tumours (46%) and breast cancer (64%) were inferior to international standards. New Zealand 25 to 29 year olds are at twice the risk of developing cancer as those 15-24 years. Given that the survival disparities identified were remarkably consistent with those for younger AYA, consideration should be given widening New Zealand's AYA age range.

    Human papillomavirus (HPV) test was incorporated into the triage of lesser abnormal cervical cytologies: atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL). This study aimed to evaluate the impact of age on the efficacy of HPV testing in patients with lesser abnormal cervical cytologies. A total of 439 patients with ASCUS or LSIL were included. The association between age groups and the diagnostic performances of HPV test for high-grade cervical intraepithelial neoplasia (CIN2+) was evaluated. Median age was 44 years (range, 17 to 75 years). ASCUS was more frequently observed in older patients while LSIL was more common in younger patients (P=0.002). CIN2+ was found in 11.3% (32/284) of the ASCUS patients and 12.9% (20/155) of patients with LSIL. Older patients with ASCUS showed lower HPV infection rates (P=0.025), but not LSIL (P=0.114). However, the prevalence of CIN2+ was similar between the age groups with ASCUS or LSIL. In patients with ASCUS, the false negative rate of HPV test for CIN2+ was 6.2%. The false negative rate of the HPV test became higher with increasing of the age after the age of 50 (P=0.034). Our findings suggest that false negative rate of the HPV test for CIN2+ in ASCUS patients older than 50 years might become higher with increasing of the age. Negative HPV results in patients of the age >50 years with ASCUS should be carefully interpreted.

    The incidence and prevalence of hypertensive emergency have been little addressed in the literature. However, over the last decade increasing numbers of young patients with different forms of hypertensive crisis have been observed in emergency departments. We performed this study to ascertain the clinical and epidemiological characteristics of patients aged ≤ 45 years admitted with a diagnosis of hypertensive emergency. We conducted an observational, descriptive, cross-sectional prospective study of 123 patients hospitalized for hypertensive emergency in the Hospital do Prenda, Luanda, between May 2011 and June 2012. Mean age was 36.62 ± 5.49 years, and most were male (52.85%). The main risk factor was hypertension (65.9%), with 17.3% complying with therapy. The most frequent forms of presentation were hypertensive encephalopathy and hemorrhagic stroke (9.8% and 82.1%, respectively). The main drugs used were diuretics, angiotensin-converting enzyme inhibitors and calcium channel blockers. Mortality during hospitalization was 25.2% (31 patients), hemorrhagic stroke being the most common cause. There was a significant association between age and in-hospital mortality. Of patients admitted with hypertensive emergency, 30.1% were aged ≤ 45 years. Hemorrhagic stroke was the most common presentation. There was a significant relationship between mode of presentation, age and in-hospital mortality. Copyright © 2013 Sociedade Portuguesa de Cardiologia. Published by Elsevier España.

    Objective: To study MRI findings of the thymus in patients with myasthenia gravis (MG) in different age groups and to analyze the relationship between the morphological changes of thymus and the MG. Methods: In total 90 patients with MG (male: female=43:47) received MR scan and were divided into four groups (group A, B, C and D) by age. Fourteen patients out of 90 received additional enhanced scan. Group A included 33 patients aged under 10 years (m:f=18:15); 27 patients aged 11-25 years were in group B (m:f=12:15); group C had 17 patients aged 26-50 years (m:f=6:11); and in group D there were 13 patients whose ages were over 51 years (m:f=7:6). And 30 Non-MG patients aged 8-75 years were selected as control group, in which the thickness, the fat collection, and glandulous atrophy of thymus was studied on CT. Results: 1) The thymus was unremarkable in 44 cases out of 90 (48.88%). 2) Enlarged thymus was shown in 42 cases out of 90 (46.66%), in which non-nodular enlargement was revealed in 34 cases and nodular enlargement in 8 cases. There were 27 cases with abnormality of thymus out of 33 (81.81%) in group A, 12 cases out of 27 (44.44%) in group B and 3 cases in group C, but no abnormality was found in group D. 3) Only 4/90 patients (4.44%) had thymic mass that respectively seen in one case of group B, two of group C and one of group D. No evidence of the involvement of the adjacent structure was found on MRI in the cases of thymic mass. No thymus enlargement was revealed in control group. Fat collection in thymus was seen in both study groups and control group. Conclusion: Intimate relationship between the abnormality of the thymus gland and MG exists in children and teenagers. While in the middle-aged patients or the seniors, further studies should be made to find out whether there is a correlation

    Objective: To analyze the prognostic value of age in patients with early stage breast cancer. Methods: The clinical characteristics of 1030 patients with early stage breast cancer (the number of positive axillary lymph nodes was less than 3) were retrospectively reviewed. Of all the patients, 468(stage I, n = 227; and stage II , n = 241) received breast conserving surgery (BCS) and 562 (stage I, n =184; and stage II, n= 378) received modified mastectomy. Patients were divided into young-age group (≤35, 136 patients), middle-age group (> 35-≤60,738 patients) and old-age group (> 60, 156 patients). The number of patients without postoperative radiation therapy after BCS is 16, 60 and 39 in the three groups, respectively. Two-dimensional conventional fractionated radiotherapy was administered. The prognostic value of the tumor size, status of axillary lymph nodes or hormonal receptors, postoperative radiation therapy were analyzed. Results: The follow-up rate was 97.86%. Of 795 patients followed up more than 5 years, 110, 569 and 116 patients were devided into the three groups, respectively. There were 40, 202 and 87 patients without radiation therapy in the three groups. The 5-year recurrence rates of the three groups were 6.2%, 8.7% and 10.4% (χ 2 = 1.14, P= 0.567). The 5-year distant metastasis rates were 4.3% , 9.5 % and 2. 5% (χ 2 = 5.31 , P = 0.070) . The 5 - year survival rates were 91.2% , 92.6% and 82.1% (χ 2 = 6. 83, P = 0.033). The young-age group had more tumors smaller than 2. 0 cm (65.4%), less positive axillary lymph nodes (13.2%), poorer differential tumor and less positive hormone acceptors (48.0%). Of patients with tumor larger than 2. 0 cm who had no radiotherapy after BCS, the 5-year survival rates were 94%, 87% and 71% (χ 2 = 20.69, P= 0.000) in the three groups. The corresponding recurrence rates were 23%, 18% ,7%, (χ 2 = 9.97, P = 0.007), and distant metastasis rates were 23%, 25% and 10% (χ 2 =8.51, P=0.014). Conclusions: The age is

    Full Text Available Background: Subdural hematoma (SDH is a common disease entity treated by neurosurgical intervention. Although the incidence increases in the elderly population, there is a paucity of studies examining their surgical outcomes. Objectives: To determine the neurological and functional outcomes of patients over 70 years of age undergoing surgical decompression for subdural hematoma. Materials and Methods: We retrospectively reviewed data on 45 patients above 70 years who underwent craniotomy or burr holes for acute, chronic or mixed subdural hematomas. We analyzed both neurological and functional status before and after surgery. Results: Forty-five patients 70 years of age or older were treated in our department during the study period. There was a significant improvement in the neurological status of patients from admission to follow up as assessed using the Markwalder grading scale (1.98 vs. 1.39; P =0.005, yet no improvement in functional outcome was observed as assessed by Glasgow Outcome Score. Forty-one patients were admitted from home, however only 20 patients (44% were discharged home, 16 (36% discharged to nursing home or rehab, 6 (13% to hospice and 3 (7% died in the postoperative period. Neurological function improved in patients who were older, had a worse pre-operative neurological status, were on anticoagulation and had chronic or mixed acute and chronic hematoma. However, no improvement in functional status was observed. Conclusion: Surgical management of SDH in patients over 70 years of age provides significant improvement in neurological status, but does not change functional status.

    Coeliac disease is characterised by an increased mortality mostly due to its complications. To study the risk of developing complications according to clinical presentation and age at diagnosis, a combined retrospective-prospective longitudinal study was performed in three Italian centres. Incidence of complications and mortality rates were calculated using type and age at diagnosis of coeliac disease, sex, and centre of diagnosis as predictors. Patients referred after being found to suffer from coeliac disease elsewhere were excluded. Between 01/1999 and 06/2015, 2225 adult coeliac patients were directly diagnosed in our centres. 17 of them developed a complication and 29 died. In patients older than 60 years at diagnosis of coeliac disease, the risk of complication is 18 times higher than in patients diagnosed at 18-40 years and 9 times higher than in patients diagnosed at 40-60 years. Classical presentation increases the risk of complications by 7 times compared to non-classical presentation; in asymptomatic patients the risk of complication is virtually absent. The risk of developing complications in coeliac patients is linked to age at diagnosis of coeliac disease and type of clinical presentation. Follow-up methods of coeliac patients should be tailored according to these parameters. Copyright © 2017. Published by Elsevier Ltd.

    Context. In recent years new observations of pre-main sequence stars (pre-MS) with Z ≤ Z⊙ have been made available. To take full advantage of the continuously growing amount of data of pre-MS stars in different environments, we need to develop updated pre-MS models for a wide range of metallicity to assign reliable ages and masses to the observed stars. Aims: We present updated evolutionary pre-MS models and isochrones for a fine grid of mass, age, metallicity, and helium values. Methods: We use a standard and well-tested stellar evolutionary code (i.e. FRANEC), that adopts outer boundary conditions from detailed and realistic atmosphere models. In this code, we incorporate additional improvements to the physical inputs related to the equation of state and the low temperature radiative opacities essential to computing low-mass stellar models. Results: We make available via internet a large database of pre-MS tracks and isochrones for a wide range of chemical compositions (Z = 0.0002-0.03), masses (M = 0.2-7.0 M⊙), and ages (1-100 Myr) for a solar-calibrated mixing length parameter α (i.e. 1.68). For each chemical composition, additional models were computed with two different mixing length values, namely α = 1.2 and 1.9. Moreover, for Z ≥ 0.008, we also provided models with two different initial deuterium abundances. The characteristics of the models have been discussed in detail and compared with other work in the literature. The main uncertainties affecting theoretical predictions have been critically discussed. Comparisons with selected data indicate that there is close agreement between theory and observation. Tracks and isochrones are available on the web at the http://astro.df.unipi.it/stellar-models/Tracks and isochrones are also available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/533/A109

    Age is considered as a risk factor in bariatric surgery. The observation was made on the basis of results from studies where patients underwent different type of surgery, but laparoscopic sleeve gastrectomy (LSG) was not among them. It is necessary to reevaluate the association of age with adverse events in the group of patients after LSG. To investigate the association of age with surgery-related adverse events in patients after LSG. Retrospective analysis of medical data was performed. The study involved 345 patients who underwent LSG in our institution between January 2013 and December 2014. The patients were subdivided by age into four groups according to quartiles. In 30-day follow-up adverse events were evaluated. We considered the presence of the following events as the endpoint of our study: death, medical events and surgical events. In general, we observed adverse events in 36 (10.4%) patients. The mortality rate in our study was 0.59%. Nineteen events were surgical and 18 medical. In 1 patient a surgical event was associated with a medical event. Bleeding was the most common surgical event and was observed in 17 (4.9%) cases. Age was not associated with surgical events (OR = 1.032, 95% CI: 0.991-1.075, p = 0.33) or medical events (OR = 0.997, 95% CI: 0.956-1.039, p = 0.89). The LSG is a safe bariatric procedure with low mortality. Bleeding is the most frequent surgical complication. Our findings suggest that age is not associated with increased risk of surgical or medical adverse events after LSG.

    The purpose of this article is to determine the accuracy and radiation dose reduction of limited-range CT prescribed from the top of L2 to the top of the pubic symphysis in children with suspected acute appendicitis. We performed a retrospective study of 210 consecutive pediatric patients from December 11, 2012, through December 11, 2014, who underwent abdominopelvic CT for suspected acute appendicitis. Two radiologists independently reviewed the theoretic limited scans from the superior L2 vertebral body to the top of the pubic symphysis, to assess for visualization of the appendix, acute appendicitis, alternative diagnoses, and incidental findings. Separately, the same parameters were assessed on the full scan by the same two reviewers. Whole-body effective doses were determined for the full- and limited-range scans and were compared using the paired t test. The appendix or entire cecum was visualized on the limited scan in all cases, and no cases of acute appendicitis were missed on the simulated limited scan compared with the full scan. Two alternative diagnoses were missed with the limited scan: one case of hydronephrosis and one of acute acalculous cholecystitis. The mean effective dose for the original scan was 5.6 mSv and that for the simulated limited scan was 3.0 mSv, resulting in a dose reduction of 46.4% (p appendicitis and reduces the dose by approximately 46%.

    In patients with acromegaly serum IGF-I is increasingly used as a marker of disease activity. As a result, the relationship between serum GH and IGF-I is of profound interest. Healthy females secrete three times more GH than males but have broadly similar serum IGF-I levels, and women with GH deficiency require 30-50% more exogenous GH to maintain the same serum IGF-I as GH-deficient men. In a selected cohort of patients with active acromegaly, studied off medical therapy using a single fasting serum GH and IGF-I measurement, we have reported previously that, for a given GH level, women have significantly lower circulating IGF-I. To evaluate the influence of age and gender on the relationship between serum GH and IGF-I in an unselected cohort of patients with acromegaly independent of disease control and medical therapy. Sixty (34 male) unselected patients with acromegaly (median age 51 years (range 24-81 years) attending a colonoscopy screening programme were studied. Forty-five had previously received pituitary radiotherapy. Patients had varying degrees of disease control and received medical therapy where appropriate. Mean serum GH was calculated from an eight-point day profile (n = 45) and values obtained during a 75-g oral glucose tolerance test (n = 15). Serum IGF-I, IGFBP-3 and acid-labile subunit were measured and the dependency of these factors on covariates such as log10 mean serum GH, sex, age and prior radiotherapy was assessed using regression techniques. The median calculated GH value was 4.7 mU/l (range 1-104). A significant linear association was observed between serum IGF-I and log10 mean serum GH for the cohort (R = 0.5, P fall by 0.37 nmol/l per year (P = 0.04, 95% CI 0.015-0.72). In keeping with previous observations of relative GH resistance in normal and GH-deficient females we have observed lower serum IGF-I levels for equivalent mean serum GH levels in females patients with acromegaly. This gender-dependent difference is independent of

    The purpose of this study was to assess the effect of age on left ventricular performance during exercise in 79 patients with coronary artery disease (greater than or equal to 50% narrowing of one or more major coronary arteries). Fifty patients under the age of 60 years (group I) and 29 patients 60 years or older (group II) were studied. Radionuclide angiograms were obtained at rest and during symptom-limited upright bicycle exercise. The history of hypertension, angina or Q wave myocardial infarction was similar in both groups. Multivessel coronary artery disease was present in 30 patients (60%) in group I and in 19 patients (66%) in group II (p . not significant). There were no significant differences between the two groups in the hemodynamic variables (at rest or during exercise) of left ventricular ejection fraction, end-diastolic volume, end-systolic volume and cardiac index. Exercise tolerance was higher in group I than in group II (7.8 +/- 0.4 versus 5.7 +/- 0.4 minutes, p . 0.009), although the exercise heart rate and rate-pressure product were not significantly different between the groups. There was poor correlation between age and ejection fraction, end-diastolic volume and end-systolic volume at rest and during exercise. Abnormal left ventricular function at rest or an abnormal response to exercise was noted in 42 patients (84%) in group I and in 25 patients (86%) in group II (p . not significant). Thus, in patients with coronary artery disease, age does not influence left ventricular function at rest or response to exercise. Older patients with coronary artery disease show changes in left ventricular function similar to those in younger patients with corresponding severity of coronary artery disease

    Full Text Available Biomarkers that drift differentially with age between normal and premalignant tissues, such as Barrett's esophagus (BE, have the potential to improve the assessment of a patient's cancer risk by providing quantitative information about how long a patient has lived with the precursor (i.e., dwell time. In the case of BE, which is a metaplastic precursor to esophageal adenocarcinoma (EAC, such biomarkers would be particularly useful because EAC risk may change with BE dwell time and it is generally not known how long a patient has lived with BE when a patient is first diagnosed with this condition. In this study we first describe a statistical analysis of DNA methylation data (both cross-sectional and longitudinal derived from tissue samples from 50 BE patients to identify and validate a set of 67 CpG dinucleotides in 51 CpG islands that undergo age-related methylomic drift. Next, we describe how this information can be used to estimate a patient's BE dwell time. We introduce a Bayesian model that incorporates longitudinal methylomic drift rates, patient age, and methylation data from individually paired BE and normal squamous tissue samples to estimate patient-specific BE onset times. Our application of the model to 30 sporadic BE patients' methylomic profiles first exposes a wide heterogeneity in patient-specific BE onset times. Furthermore, independent application of this method to a cohort of 22 familial BE (FBE patients reveals significantly earlier mean BE onset times. Our analysis supports the conjecture that differential methylomic drift occurs in BE (relative to normal squamous tissue and hence allows quantitative estimation of the time that a BE patient has lived with BE.

    Exploratory case-control study. Writer's cramp (WC) is a type of focal hand dystonia. The central nervous system plays a role in its pathophysiology, but abnormalities in the affected musculoskeletal components may also be relevant. We compared the active range of motion (ROM) in patients with WC and healthy volunteers (HVs) and correlated the findings with disease duration and severity. Affected limb joints were measured with goniometers. Patients were assessed at least 3 months after their last botulinum toxin (botulinum neurotoxin) injection, and strength was clinically normal. t tests were used to compare the ROMs of WC with matched HVs. The Spearman correlation coefficient assessed the relationship of active ROMs to the disease duration and handwriting subscore of the Dystonia Disability Scale. ROMs of D1 metacarpophalangeal (MCP) joint extension as well as D2 and D5 MCP flexion were significantly smaller in WC, and distal interphalangeal joint extension in D3 and D5 was significantly greater compared with HVs. There were negative correlations between D2 MCP flexion and disease duration and with Dystonia Disability Scale. Abnormalities in ROMs in WC were found. Severity and disease duration correlated with reduced D2 MCP flexion. This may be related to intrinsic biomechanical abnormalities, co-contraction of muscles, or a combination of subclinical weakness and atrophy from repeated botulinum neurotoxin injections. Hand biomechanical properties should not be ignored in the pathophysiology of WC. 2c. Copyright © 2016 Hanley & Belfus. All rights reserved.

    There have been a limited number of studies comparing bone mass between patients with schizophrenia and the general population. The aim of this study was to compare the bone mass of schizophrenia patients with that of healthy subjects in Japan. We recruited patients (n = 362), aged 48.8 ± 15.4 (mean ± SD) years who were diagnosed with schizophrenia or schizoaffective disorder based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). Bone mass was measured using quantitative ultrasound densitometry of the calcaneus. The osteosono-assessment index (OSI) was calculated as a function of the speed of sound and the transmission index. For comparative analysis, OSI data from 832 adults who participated in the Iwaki Health Promotion Project 2009 was used as representative of the general community. Mean OSI values among male schizophrenic patients were lower than those in the general population in the case of individuals aged 40 and older. In females, mean OSI values among schizophrenic patients were lower than those in the general community in those aged 60 and older. In an analysis using the general linear model, a significant interaction was observed between subject groups and age in males. Older schizophrenic patients exhibit lower bone mass than that observed in the general population. Our data also demonstrate gender and group differences among schizophrenic patients and controls with regard to changes in bone mass associated with aging. These results indicate that intervention programs designed to delay or prevent decreased bone mass in schizophrenic patients might be tailored according to gender.

    Physical function (PF) is a core patient-reported outcome domain in clinical trials in rheumatic diseases. Frequently used PF measures have ceiling effects, leading to large sample size requirements and low sensitivity to change. In most of these instruments, the response category that indicates the highest PF level is the statement that one is able to perform a given physical activity without any limitations or difficulty. This study investigates whether using an item format with an extended response scale, allowing respondents to state that the performance of an activity is easy or very easy, increases the range of precise measurement of self-reported PF. Three five-item PF short forms were constructed from the Patient-Reported Outcomes Measurement Information System (PROMIS®) wave 1 data. All forms included the same physical activities but varied in item stem and response scale: format A ("Are you able to …"; "without any difficulty"/"unable to do"); format B ("Does your health now limit you …"; "not at all"/"cannot do"); format C ("How difficult is it for you to …"; "very easy"/"impossible"). Each short-form item was answered by 2217-2835 subjects. We evaluated unidimensionality and estimated a graded response model for the 15 short-form items and remaining 119 items of the PROMIS PF bank to compare item and test information for the short forms along the PF continuum. We then used simulated data for five groups with different PF levels to illustrate differences in scoring precision between the short forms using different item formats. Sufficient unidimensionality of all short-form items and the original PF item bank was supported. Compared to formats A and B, format C increased the range of reliable measurement by about 0.5 standard deviations on the positive side of the PF continuum of the sample, provided more item information, and was more useful in distinguishing known groups with above-average functioning. Using an item format with an extended

    Sepsis is a major cause of morbidity and mortality, especially at the extremes of age. To understand the human age-specific transcriptomic response to sepsis, a multi-cohort, pooled analysis was conducted on adults, children, infants, and neonates with and without sepsis. Nine public whole-blood gene expression datasets (636 patients) were employed. Age impacted the transcriptomic host response to sepsis. Gene expression from septic neonates and adults was more dissimilar whereas infants and children were more similar. Neonates showed reductions in inflammatory recognition and signaling pathways compared to all other age groups. Likewise, adults demonstrated decreased pathogen sensing, inflammation, and myeloid cell function, as compared to children. This may help to explain the increased incidence of sepsis-related organ failure and death in adults. The number of dysregulated genes in septic patients was proportional to age and significantly differed among septic adults, children, infants, and neonates. Overall, children manifested a greater transcriptomic intensity to sepsis as compared to the other age groups. The transcriptomic magnitude for adults and neonates was dramatically reduced as compared to children and infants. These findings suggest that the transcriptomic response to sepsis is age-dependent, and diagnostic and therapeutic efforts to identify and treat sepsis will have to consider age as an important variable.

    Age-related macular degeneration is a multifactorial disease that can lead to vision impairment in older individuals. Although the etiology of age-related macular degeneration remains unknown, risk factors include age, ethnicity, smoking, hypertension, obesity, and genetic factors. Two main loci have been identified through genome-wide association studies, on chromosomes 1 and 10. Among the variants located at the 10q26 region, rs11200638, located at the HTRA1 gene promoter, has been associated with age-related macular degeneration in several populations and is considered the main polymorphism. We conducted a replication case-control study to analyze the frequency and participation of rs11200638 in the etiology of age-related macular degeneration in a sample of patients and controls from the State of São Paulo, Brazil, through polymerase chain reaction and enzymatic digestion. The frequency of the A allele was 57.60% in patients with age-related macular degeneration and 36.45% in controls (p value age-related macular degeneration group compared to the control group (p = 1.21 e-07 and 0.0357, respectively). No statistically significant results were observed after stratification in dry versus wet types or advanced versus non-advanced forms. To our knowledge, this is the first time the association between rs11200638 and overall age-related macular degeneration has been reported in South America.

    Computed tomographic images of brains from 26 individuals (10 males and 16 females) with Down syndrome were analysed for roentgenographic measurement. Their ages ranged from 14 to 47 years, the average being 28 years. The results showed that their Sylvian fissure ratio was larger in the aged group. A high incidence of calcification in basal ganglia, choroid plexus and pineal body was noted (85%). An increased Sylvian fissure ratio and a high incidence of intracranial calcification may be practically used as representatives of premature aging. Furthermore, a high incidence of mega cisterna magna implicates that it is worthy of study whether individuals with Down syndrome have a predisposition to underdevelopment of cerebellum. (author)

    The purpose of this work was to compare the clinical adaptation of prompt gamma (PG) imaging and positron emission tomography (PET) as independent tools for non-invasive proton beam range verification and treatment validation. The PG range correlation and its differences with PET have been modeled for the first time in a highly heterogeneous tissue environment, using different field sizes and configurations. Four patients with different tumor locations (head and neck, prostate, spine and abdomen) were chosen to compare the site-specific behaviors of the PG and PET images, using both passive scattered and pencil beam fields. Accurate reconstruction of dose, PG and PET distributions was achieved by using the planning computed tomography (CT) image in a validated GEANT4-based Monte Carlo code capable of modeling the treatment nozzle and patient anatomy in detail. The physical and biological washout phenomenon and decay half-lives for PET activity for the most abundant isotopes such as 11C, 15O, 13N, 30P and 38K were taken into account in the data analysis. The attenuation of the gamma signal after traversing the patient geometry and respective detection efficiencies were estimated for both methods to ensure proper comparison. The projected dose, PG and PET profiles along many lines in the beam direction were analyzed to investigate the correlation consistency across the beam width. For all subjects, the PG method showed on average approximately 10 times higher gamma production rates than the PET method before, and 60 to 80 times higher production after including the washout correction and acquisition time delay. This rate strongly depended on tissue density and elemental composition. For broad passive scattered fields, it was demonstrated that large differences exist between PG and PET signal falloff positions and the correlation with the dose distribution for different lines in the beam direction. These variations also depended on the treatment site and the

    Whenever we discuss the overall results of surgical treatment for unruptured cerebral aneurysms, especially in aged patients, we tend to consider advanced age or general anesthesia as causes for unfavorable results. There are no reports concerning ischemic stroke events following general anesthesia in aged patients with a prior history of cerebrovascular disease. The purpose of this study is to clarify the influence of general anesthesia on the brats in aged patients with a previous history of ischemic cerebrovascular disease. The subjects were 30 consecutive patients over 70 years of age with previous ischemic cerebrovascular disease who underwent various surgeries except brain and cardiac surgery under general anesthesia. The patients were 70 to 85 years old, with a mean age of 76. Twenty-three were men and 7 were women. Surgical procedures were 12 gastrointestinal, 6 orthopedic and 4 urogenital and others. The type of cerebrovascular disease evaluated by neuroradiologist and anesthesiologist based on MR imaging was devided as follows: 16 patients had minor stroke, 7 had transient ischemic attack/reversible ischemic neurological deficit (TIA/RIND) and 7 had asymptomatic cerebral infarction. MR angiography was also assessed to evaluate the main artery in the brain. Blood pressure and arterial blood gas (PaCO 2 ) during general anesthesia were analyzed, and the rate of systemic and neurological complications following general anesthesia were evaluated. MR angiography revealed no occlusion or severe stenosis of the main artery in the brain of any of the patients. The minimum systolic blood pressure showed less than 100 mmHg transiently for 5-20 minutes in 28 of 30 patients during general anesthesia. The minimum value was 65 mmHg maintained for 5 minutes. The minimum PaCO 2 during general anesthesia was as follows: 1 case 36 mmHg. There were no neurological complications following general anesthesia in this study. One of 30 patients (3.3%) had suffered from pneumonia

    Seizure threshold (ST) in electroconvulsive therapy (ECT) has not been reported previously in Japanese patients. We investigated ST in bilateral ECT in Japanese patients using the dose-titration method. The associations between demographic and clinical characteristics and ST were analyzed to identify the predictors of ST. Finally, the validity of the half-age method for the stimulus dose was evaluated. Fifty-four Japanese patients with mood disorder, schizophrenia, and other psychotic disorders received an acute course of bilateral ECT using a brief-pulse device. ST was determined at the first session using a fixed titration schedule. ST was correlated with age, sex, body mass index, history of previous ECT, and psychotropic drugs on multiple regression analysis. Furthermore, the rate of accomplished seizures was calculated using the half-age method. Mean ST was 136 mC. ST was influenced by age, sex, history of previous ECT, and medication with benzodiazepines. The accomplished seizure rate using the half-age method was 72%, which was significantly lower in men and subjects on benzodiazepines. ST in Japanese patients was equal to or slightly higher than that previously reported in other ethnic groups, which might be attributable, at least in part, to high prevalence of and large-dose benzodiazepine prescription. Higher age, male gender, no history of ECT, and benzodiazepines were related to higher ST. The half-age method was especially useful in female patients and subjects without benzodiazepine medication. © 2014 The Authors.

    Altered brain connectivity is implicated in the development and clinical burden of schizophrenia. Relative to matched controls, schizophrenia patients show (1) a global and regional reduction in the integrity of the brain's white matter (WM), assessed using diffusion tensor imaging (DTI) fractional anisotropy (FA), and (2) accelerated age-related decline in FA values. In the largest mega-analysis to date, we tested if differences in the trajectories of WM tract development influenced patient-control differences in FA. We also assessed if specific tracts showed exacerbated decline with aging. Three cohorts of schizophrenia patients (total n = 177) and controls (total n = 249; age = 18-61 years) were ascertained with three 3T Siemens MRI scanners. Whole-brain and regional FA values were extracted using ENIGMA-DTI protocols. Statistics were evaluated using mega- and meta-analyses to detect effects of diagnosis and age-by-diagnosis interactions. In mega-analysis of whole-brain averaged FA, schizophrenia patients had lower FA (P = 10 -11 ) and faster age-related decline in FA (P = 0.02) compared with controls. Tract-specific heterochronicity measures, that is, abnormal rates of adolescent maturation and aging explained approximately 50% of the regional variance effects of diagnosis and age-by-diagnosis interaction in patients. Interactive, three-dimensional visualization of the results is available at www.enigma-viewer.org. WM tracts that mature later in life appeared more sensitive to the pathophysiology of schizophrenia and were more susceptible to faster age-related decline in FA values.

    The incidence of arterial disease increases with age. Increasing life expectancy in the western world will intensify demands on vascular surgeons with regard to increasing caseload, expanding patient selection criteria, and more complex and minimally-invasive treatment options. We analysed our arterial cases over the past 31 years (n = 6,144) and compared our methods of intervention and complication rates in the elderly population (>75) with the younger cohort, in order to determine whether age should influence our management strategies.

    Full Text Available To survey airborne and food allergen patterns in southern Taiwan and to analyze the effect of age on response to different allergens, we tested samples from 4,411 allergic patients at Kaohsiung Medical University Hospital using the MAST-CLA test (new Taiwan panel. A total of 2,212 (50.1% samples showed a positive response. We grouped allergic patients into five age groups. Milk and egg white were the main food allergens in the younger groups (< 3 years old and 3-6 years old. Shrimp, crab, and shellfish were the main allergens in the groups aged 7-12, 13-18, and more than 18 years. Among airborne allergens, house dust and mites Dermatophagoides farinae and D. pteronyssinus were the main allergens in all age groups, whereas the frequency of response to cockroach allergen was low in the group aged less than 3 years, but increased in the other age groups. There was a sharp increase in the frequency of response to airborne allergens after 3 years old and a sharp decrease in response to food allergens. Among subjects allergic to both airborne and food allergens, there was a positive MAST-CLA rate of 19.9% to 26% (all five age groups, no significant difference. When we compared our results with those from Taipei Veterans General Hospital in northern Taiwan, there were significant differences for yeast, peanut, feather mix, dog dander, cockroach, D. farinae and D. pteronyssinus allergens (p < 0.01. These differences were probably caused by differences in patient location, patient age, disease patterns and allergen panels.

    Purpose: We report the experience of two French cancer centers in the treatment of oral cavity squamous cell carcinoma (SCC) in patients aged ≥80 years. Materials and methods: Two hundred and sixty patients aged ≥80 years with a primary oral cavity SCC were included in this retrospective analysis. Results: Sex ratio was near to 1. Tobacco or alcohol intoxication was the main risk factor for 66% of men and 16% of women and leukoplakia, lichen planus, or oral traumatism for 55% of women and 11% of men (p < 0.0001). Two hundred patients received a loco-regional (LR) treatment with a curative intent (surgery and/or radiotherapy), 29 with a palliative intent and 31 did not receive a LR treatment. Curative treatments were initially planned to be adapted to age in 118 patients (59%). The median disease-specific survival (DSS) was 29 months. In multivariate analysis, the independent prognostic factors for DSS were stage (HR = 0.42 [0.24-0.72]), age (HR = 0.43 [0.24-0.75]) and performance status (HR = 0.50 [0.27-0.95]). The median overall survival (OS) was 14 months. In multivariate analysis, the independent prognostic factors for OS were age (HR = 0.52 [0.35-0.79]), stage (HR = 0.56 [0.38-0.84]), tumor differentiation (HR = 0.60 [0.33-0.93]) and performance status (HR = 0.6 [0.37-0.97]). In patients treated with a curative intent, treatment adapted to age was not associated with a decreased overall survival or disease-specific survival as compared with the standard treatment. However, prophylactic lymph node treatment in stages I-II tumors decreased the rate of nodal recurrence from 38% to 6% (p = 0.01). Conclusion: This study emphasizes the need for prospective evaluation of standard and adapted schedules in elderly patients with oral cavity cancer.

    Temporomandibular Disorders (TMD) refer to several common clinical disorders which involve the masticatory muscles, the temporomandibular joint (TMJ) and the adjacent structures. Although neck signs and symptoms are found with higher prevalence in TMD patients compared to the overall population, whether limitation of cervical mobility is an additional positive finding in this cohort is still an open question. To compare the physiological cervical range of motion (CROM) and the extent of rotation during cervical flexion (flexion-rotation test, FRT) in people with TMD (muscular origin) and healthy control subjects. The range of motion of the neck and FRT was measured in 20 women with myogenic TMD and 20 age matched healthy controls. Women with myogenic TMD had significantly lower FRT scores compared to their matched healthy women. No difference was found between groups in CROM in any of the planes of movement. The FRT was positive (less than 32°) in 90% of the TMD participants versus 5% in the healthy control but the findings were not correlated with TMD severity. The results point out a potential involvement of the upper cervical joints (c1-c2) in women with myogenic TMD. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The aim of this study was to dissociate age and duration of illness effects on cognitive impairment of patients with relapsing-remitting multiple sclerosis. Cognitive impairment among patients with multiple sclerosis (MS) is well known. However, few studies were devoted to assess the respective role of disease duration and age on cognitive functions in MS patients. Therefore, two studies were carried out on relapsing-remitting MS (RR-MS) patients using some tests of the BCcogSEP--a French test battery evaluating cognitive functions in MS. The cognitive deficits of RR-MS patients aged 50 years and over and whose symptoms had been present for more than 20 years were more severe than those of MS patients with a shorter illness duration (less than 10 years) or matched-age control participants. The more impaired cognitive functions were information-processing speed, episodic memory, verbal fluency and attention. On the other hand, cognitive performances of young RR-MS patients were similar to those of older RR-MS patients when all patients had the same illness duration (8 years in this study). Older patients even achieved better performance than younger ones on verbal fluency. This can be partly explained by the theory of cognitive reserve, as reported in previous cognitive aging studies. In RR-MS patients, the influence of illness duration seems to be a predominant factor in the development of cognitive impairment.

    Full Text Available Objective: the probable determination of severe sepsis in patients of elderly and senile age with necrotic erysipelas based on a comprehensive assessment (clinical examination using systems — scales and determination of the level markers of SIRS. Material and methods. The analysis of peculiarities of necrotic erysipelas clinical course in 59 patients. The first group consisted of 17 patients with severe sepsis, the second — 18 patients with sepsis without multiple organ failure, in the comparison group —22 patients with local infection. We determined albumin, urea, creatinine, pro-calcitonin of plasma. The scale SAPS III was used to quantify SIRS, scale SOFA —to determine the extent of damage to organs and systems. Results. The most sensitive marker of developing sepsis in patients with necrotic erysipelas was procalcitonin. The second important indicator of SIRS severity in patients with necrotic erysipelas was the blood albumin. Scale SAPS III also allows to select a group of patients with high risk of developing severe sepsis. Use of the SOFA to predict the scale has been found out to be less important. Conclusion. A comprehensive assessment of the severity of the condition by scale SAPS III in combination with determining the levels of procalcitonin and plasma albumin is advisable to apply for prediction the probability of developing severe sepsis in patients of elderly and senile age with necrotic erysipelas. For the last indicator it is important to assess of absolute values and the decrease of its concentration.

    To evaluate which patients older tahn 70 years will benefit by radiotherapy for their brain metastases the data of 35 patients in this age-group who were treated between 1983 and 1994 were retrospectivley analyzed. All patients were previously untreated and received a whole-brain irradiation and concomitantly corticosteroids. The median total dose was 30 Gy (fractionation: 10 times 3 Gy in 2 weeks). Six patients each received lower or higher total doses with 50.4 Gy at maximum. Six patients failed to complete their prescribed treatment (17%). The median survival of all patients who completed their radiotherapy course was 67 days only. Patients with extracerebral metastases had a median survival of 31 days. Survival was not dependent on total dose of radiotherapy. In 56% of all cases the general condition of the patients improved or remained stable at a high level. Karnofsky-performance status was the most important prognostic factor. Advanced age is an unfavourable prognostic factor. Only patients in good general condition without extracerebral metastases had survival times which justify radiotherapy for their brain metastases. (orig./MG) [de

The most important patient expectations concern certain types of information: explanation of disease and treatment, health promotion, and improvement in quality of life. Other demands include proper rapport and emotional support. The aim of this paper was to examine different patient groups over the age of 50 years and their expectations toward medical visits, evaluated before a visit and after the visit.Patients and methods: The study group consisted of 4,921 primary health-care patients. The patients received self-administered questionnaires that they filled in before and after the appointment with the doctor. Interviews with patients were conducted individually by specially trained interviewers. The PRACTA Patient Expectations Scale was used to measure the appointment-related expectations of the patients.Results: We observed differences related to age in patients’ expectations before medical visits regarding the following factors: disease explanation, treatment explanation, quality of life, rapport, and emotional support. The same differences were not observed on health promotion. Evaluation of patients’ appointment-related experiences after the visit showed that there were significant differences between the age-groups regarding all types of expectations included in the study. Differences between previsit and

    To determine the relationship between growth potential in culture and the age of the patient, skin biopsies were obtained from over 60 patients of varying ages. The relationship between the length of time elapsed since burn injury and growth potential was also examined, using biopsies obtained from patients with burns during their treatment. Keratinocytes were extracted from biopsies and assessed for colony-forming ability by standard methods. Repeated subculture of cells was undertaken to determine the reproductive capacity of cells in vitro. Age had no effect on the colony-forming ability of keratinocytes in primary culture; however age did affect the total number of generations achieved by these cells. The growth potential of keratinocytes from patients with severe burns showed considerable variation according to the amount of time which had elapsed since the injury. This was most apparent around one week post-burn. These results need to be investigated further to understand their clinical implications. The study provides an insight into the influence of age and physiological response on the wound healing process in burn injuries.

  3. Age as a factor in assessing risks to patients from the use of x-rays

    Le Heron, J.

    1996-01-01

    Effective dose is currently widely used as a means of quantifying patient dose (and hence patient risk) in diagnostic radiology. Its appeal stems primarily from being able to normalise partial body irradiations into equivalent whole body irradiations, and additionally from being linked to a sound definition of radiation detriment. However there are several aspects of effective dose that should lead to its use being accompnied by a degree of caution. One such factor is age. Calculation of age specific tissue weighting factors for the tissues used in the formulation of effective dose show that the relative contributions of the tissues vary considerably as a function of age. When this is combined with age specific risk factors for cancers and hereditary effects, the implications of a given 'effective dose' for an x-ray procedure depend markedly on the age of the patient. Because of the elderly component of the patient population, the ensuing risks arising from diagnostic radiology are at a level considerably less than that assessed using the population-averaged approach.

    Age-related X-ray features of the spine in patients with achondroplasia are studied. It gives the time course of changes in the shape of vertebrae, the specific features of apophyseal ossification, provides a quantitative account of the shorter caudal lumbar vertebral arch root distance symptom. The time course of changes in the size of the lumbosacral angle was examined. The findings suggest that there are not only considerable static changes in the spine of patients with achondroplasia, but also significant age-related features of vertebral tissue growth and differentiation [ru

    Utility of visual impairment caused by amblyopia is important for the cost-effectiveness of screening for amblyopia (lazy eye, prevalence 3-3.5 %). We previously measured decrease of utility in 35-year-old persons with unilateral persistent amblyopia. The current observational case-control study aimed to measure loss of utility in patients with amblyopia with recent decrease of vision in their better eye. As these patients are rare, the sample was supplemented by patients with bilateral age-related macular degeneration with similar decrease of vision. From our out-patient department, two groups of patients with recent deterioration to bilateral visual acuity less than Snellen 0.5 (bilateral visual impairment, BVI) were recruited, with either persistent amblyopia and age-related macular degeneration (AMB + AMD), or with bilateral age-related macular degeneration (BAMD). To measure utility, the time trade-off method and the standard gamble method were applied through interviews. Correlations were sought between utility values and visual acuity, age and Visual Function Questionnaire-25 scores. Seventeen AMB + AMD patients (mean age 72.9 years), and 63 BAMD patients (mean age 79.6 years) were included in the study. Among AMB + AMD, 80 % were willing to trade lifetime in exchange for cure. The overall mean time trade-off utility was 0.925. Among BAMD, 75 % were willing to trade, utility was 0.917. Among AMB + AMD, 38 % accepted risk of death in exchange for cure, overall mean standard gamble utility was 0.999. Among BAMD, 49 % accepted risk of death, utility was 0.998. Utility was not related to visual acuity but it was to age (p = 0.02). Elderly patients with BVI, caused by persistent amblyopia and age-related macular degeneration (AMD) or by bilateral AMD, had an approximately 8 % loss of TTO utility. Notably, the 8 % loss in elderly with BVI differs little from the 3.7 % loss we found previously in 35-year-old persons with unilateral

    Retrospective. The authors hypothesized that cervical lordosis (CL) would decrease with aging and increasing degeneration. It is theorized that with age and degeneration, the cervical spine loses lordosis and becomes progressively more kyphotic; however, no studies support these conclusions in patients with various spinal deformities. The authors performed a radiographic analysis of asymptomatic adults (referring to their cervical spine) of varying ages, with differing forms of spinal deformity to the thoracic/lumbar spine to see how cervical lordosis changes with increasing age. A total of 104 total spine EOS X-rays of adult (aged >18 years) spinal deformity patients without documented neck pain, prior neck surgery, or cervical deformity were reviewed. The researchers only reviewed EOS X-rays because they allow complete visualization from occiput to feet. Cervical lordosis, standard Cobb measurements, sagittal balance parameters, and cervical degeneration were quantified radiographically by the method previously described by Gore et al. Statistical analysis was performed with 1-way analysis of variance to compare significant differences between groups aged 60 years as well as changes in sagittal balance. A p-value 60 years, respectively; p 60 years, respectively; p < .01), with the highest degeneration at the C5-6 and C6-7 disc spaces (3.7 ± 3.3 and 3.2 ± 2.9, respectively; p < .01). This increase did not correlate with the increase in CL seen with aging (r = 0.02; p = .84). Cervical lordosis increased with aging in adult spinal deformity patients. There was no relationship between cervical degeneration and lordosis despite the strong relationship seen between increasing CL in older age groups. Copyright © 2014 Scoliosis Research Society.

    Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

    Tissue regeneration is impaired in aged individuals. Adipose-derived mesenchymal stromal cells (ADSCs), a promising source for cell therapy, were shown to secrete various angiogenic factors and improve vascularization of ischemic tissues. We analyzed how patient age affected the angiogenic properties of ADSCs. ADSCs were isolated from subcutaneous fat tissue of patients with coronary artery disease (CAD; n = 64, 43-77 years old) and without CAD (n = 31, 2-82 years old). ADSC phenotype characterized by flow cytometry was CD90(+)/CD73(+)/CD105(+)/CD45(-)/CD31(-) for all samples, and these cells were capable of adipogenic and osteogenic differentiation. ADSCs from aged patients had shorter telomeres (quantitative reverse transcription polymerase chain reaction) and a tendency to attenuated telomerase activity. ADSC-conditioned media (ADSC-CM) stimulated capillary-like tube formation by endothelial cells (EA.hy926), and this effect significantly decreased with the age of patients both with and without CAD. Angiogenic factors (vascular endothelial growth factor, placental growth factor, hepatocyte growth factor, angiopoetin-1, and angiogenin) in ADSC-CM measured by enzyme-linked immunosorbent assay significantly decreased with patient age, whereas levels of antiangiogenic factors thrombospondin-1 and endostatin did not. Expression of angiogenic factors in ADSCs did not change with patient age (real-time polymerase chain reaction); however, gene expression of factors related to extracellular proteolysis (urokinase and its receptor, plasminogen activator inhibitor-1) and urokinase-type plasminogen activator receptor surface expression increased in ADSCs from aged patients with CAD. ADSCs from aged patients both with and without CAD acquire aging characteristics, and their angiogenic potential declines because of decreasing proangiogenic factor secretion. This could restrict the effectiveness of autologous cell therapy with ADSCs in aged patients.

    Full Text Available Secondary hyperparathyroidism (SHPTH can develop early in the course of chronic renal failure and becomes more prominent as kidney function declines. We studied the effect of diabetes, age, and dialysis on parathyroid function in 60 (21 women, 39 males; 44 non-diabetic, 16 diabetic hemodialysis (HD patients. Serum intact PTH (iPTH, calcium, phosphorus, alkaline phosphatase (ALP, and magnesium (Mg were measured. Adequacy of HD was evaluated by calculating the urea reduction rate (URR. There were significantly lower values of serum iPTH, ALP, and dialysis adequacy among diabetic than non-diabetes HD patients. In addition, there were an inverse correlation of age and serum iPTH (r= -0.27, p= 0.034 as well as age and serum phosphorus (r= -0.28, p= 0.031. There was also a positive correlation between serum iPTH with the duration (r= 0.001, p=0.42 and doses of dialysis treatment (r= 0.38, p= 0.002. We conclude that a significant negative correlation between age and serum phosphorus and lower parathyroid activity in diabetic HD patients, which implies more prevalence of bone disease in elderly diabetic HD patients. Further study of bone disease in this group of patients is required to evaluate its effect on outcome and different therapeutic interventions.

    Resistant hypertension, defined as blood pressure >140/90 mm Hg despite using ≥3 antihypertensive medications, is a well-recognized clinical entity. Patients with resistant hypertension are at an increased risk of cardiovascular disease compared with those with more easily controlled hypertension. Coronary heart disease mortality rates of younger adults are stagnating or on the rise. The purpose of our study was to characterize the phenotype and risk factors of younger patients with resistant hypertension, given the dearth of data on cardiovascular risk profile in this cohort. We conducted a cross-sectional analysis with predefined age groups of a large, ethnically diverse cohort of 2170 patients referred to the Hypertension Clinic at the University of Alabama at Birmingham. Patients (n=2068) met the inclusion criteria and were classified by age groups, that is, ≤40 years (12.7% of total cohort), 41 to 55 years (32.1%), 56 to 70 years (36.1%), and ≥71 years (19.1%). Patients aged ≤40 years compared with those aged ≥71 years had significantly earlier onset of hypertension (24.7±7.4 versus 55.0±14.1 years; P hypertension, younger individuals have a distinct phenotype characterized by overlapping risk factors and comorbidities, including obesity, high aldosterone, and high dietary sodium intake compared with elderly. © 2017 American Heart Association, Inc.

    Full Text Available Purpose. To investigate the activity of antioxidative enzymes and the products of oxidative stress in patients with age-related cataracts and compare the findings with those in healthy control subjects. Method. Sixty patients with age-related cataract and sixty healthy controls of matched age and gender were included in this study. Serum samples were obtained to detect the antioxidative enzymes of superoxide dismutase (SOD, catalase (CAT, and glutathione peroxidase (GSH-Px, and oxidation degradation products of malondialdehyde (MDA, 4-hydroxynonenal (4-HNE, conjugated diene (CD, advanced oxidation protein products (AOPP, protein carbonyl (PC, and 8-hydroxydeoxyguanosine (8-OHdG. Results. Serum SOD, GSH-Px, and CAT activities in cataract group were significantly decreased as compared to the control subjects (P<0.05. The levels of MDA, 4-HNE, and CD in cataract patients were significantly higher than those in the control subjects (P<0.05, P<0.01. Cataract patients had higher levels of 8-OHdG, AOPP, and PC with respect to the comparative group of normal subjects (P<0.01. And there was no statistical significance in concentration of antioxidative enzymes and oxidative stress products in patients with different subtype cataract. Conclusions. Oxidative stress is an important risk factor in the development of age-related cataract, and augmentation of the antioxidant defence systems may be of benefit to prevent or delay cataractogenesis.

    Traditionally, patient empowerment has been used as a strategy for health promotion. The rise of online communities of patients represents a good example of how patient empowerment occurs, independently of the intervention of existing healthcare providers and insurers, allowing thus a more accurate definition of meaning of this concept. We describe two situations related with the development of health-related social networks: (1) The emergence of a new biomedical research model in which patients lead research, shifting the equilibrium of power from the professionals to research subjects themselves, and (2) The emergence of Lay Crowd-Sourced Expertise in these communities, arising from the daily exchange among patients affected by chronic conditions and their relatives, giving place to a new era of bottom-up data generation, previously unknown in biomedical sciences. We enrich these descriptions by analyzing interviews to key actors of these "on line" communities": Michael Chekroun, founder of "Carenity, France", and Paul Wicks Vice President at "PatientsLikeMe, USA".

    The relationship between nurses' job satisfaction and their perceptions of quality of care has been examined in previous studies. There is little evidence, however, about relationships between the job satisfaction of nursing staff and quality of care perceived by the patients. The aim of this study was to analyze, how the job satisfaction of nursing staff, organizational characteristics (hospital and unit type), and patients' age relate to patients' perceptions of the quality of care. The study was cross-sectional and descriptive, based on a secondary analysis of survey data acquired during the At Safe study in Finland. The study included 98 units at four acute care hospitals between autumn 2008 and spring 2009. The participants were 1909 patients and 929 nursing staff. Patients' perceptions of quality of care were measured using the 42-item RHCS questionnaire. Job satisfaction of nursing staff was measured with the 37-item KUHJSS scale. Statistical analyses included descriptive statistics, principal component analysis, t-tests, analysis of variance, linear regression, and multivariate analysis of variance. Patients' perceptions of overall quality of care were positively related to general job satisfaction of nursing staff. Adequate numbers of staff appeared to be the clearest aspect affecting quality of care. Older patients were more satisfied with staff number than younger patients. Patients cared for in outpatient departments felt more respected than patients in wards, whereas patients in wards reported better care of basic needs (e.g., hygiene, food) than outpatients. The evaluation of resources by nursing staff is related to patients' perceptions of the adequacy of nursing staff levels in the unit. The results emphasize the importance of considering patients' perceptions of the quality of care and assessments by nurses of their job satisfaction at the hospital unit level when evaluating quality of care.

    Aging is well known as one of the major causes of a reduced glomerular filtration rate (GFR). The resistive index (RI) measured by renal Doppler ultrasonography (RDU) is thought to be a good indicator of renal vascular resistance induced by arteriosclerosis. In this study, we investigated whether RI could be used to evaluate the pathogenesis of renal damage or the mechanisms of reduction of renal function by aging. We investigated the correlation between RI and multiple clinical parameters and the influence of aging on the renal hemodynamic status of 194 in-patients (mean age 66.2 years) who underwent RDU at our hospital between February 2009 and July 2010. RI was significantly correlated with the age, estimated GFR (eGFR), diastolic blood pressure, pulse pressure, and degree of albuminuria. Subjects aged ≥75 years showed a significantly higher correlation coefficient between eGFR and RI. RI showed a stronger correlation with age in subjects aged ≥75 years compared to eGFR. The present study showed that renal vascular resistance and intra-renal arteriosclerosis had a greater impact on renal function in older than younger subjects, reflecting the possible mechanisms of renal function reduction due to aging.

    Full Text Available Background and aims: Maximum phonation time (MPT, which is related to respiratory function, is widely used to evaluate maximum vocal capabilities, because its use is non-invasive, quick, and inexpensive. We aimed to examine differences in MPT by age, following recovery phase II cardiac rehabilitation (CR. Methods: This longitudinal observational study assessed 50 consecutive cardiac patients who were divided into the middle-aged group (<65 years, n = 29 and older-aged group (≥65 years, n = 21. MPTs were measured at 1 and 3 months after cardiac surgery, and were compared. Results: The duration of MPT increased more significantly from month 1 to month 3 in the middle-aged group (19.2 ± 7.8 to 27.1 ± 11.6 s, p < 0.001 than in the older-aged group (12.6 ± 3.5 to 17.9 ± 6.0 s, p < 0.001. However, no statistically significant difference occurred in the % change of MPT from 1 month to 3 months after cardiac surgery between the middle-aged group and older-aged group, respectively (41.1% vs. 42.1%. In addition, there were no significant interactions of MPT in the two groups for 1 versus 3 months (F = 1.65, p = 0.20. Conclusion: Following phase II, CR improved MPT for all cardiac surgery patients.

    Obstructive sleep apnoea syndrome is associated with significant morbidity. A high prevalence of obstructive sleep apnoea (OSA) symptoms has been reported in patients with asthma and chronic obstructive pulmonary disease (COPD). There are limited studies regarding relationship between atopy and OSA. To study the risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients by a home based sleep study and its association with atopy. Patients with asthma and COPD were evaluated for OSA symptoms by Epworth sleepiness scale (ESS) and Berlin questionnaire (BQ). ESS score > or = 9 was considered as high risk for OSA. Patients having high risk for OSA by ESS and BQ were further evaluated for OSA by home based sleep study. Skin prick test against common allergens was done to diagnose atopy in these patients. Among 400 patients (229, 57.25% male and 171, 42.75% female) 328 were asthmatics and 72 were COPD patients. ESS and BQ was positive in 11.25% (45/400) and 18.25% (73/400) patients respectively. ESS was positive in 10.67% (35/328) of asthma and 13.88% (10/72) of COPD patients. BQ was positive in 18.29% (60/328) of asthmatic and 18.05% (13/72) of COPD patients. Skin prick test was positive in 74.16% patients. The maximum positivity was found in asthmatics (139/155, 89.68%) compared to COPD patients (16/155, 10.32%). Skin prick test was done for 40 patients out of 73 of Asthma and COPD patients who were found positive by ESS and BQ. 72.5% patients were found to be atopic. Out of 19 patients in whom home polysomnography was done, 13 patients consented for skin prick test with common aeroallergens and 9 (69.23%) patients were found to be atopic. There is an increased risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients. Atopy could be associated with OSA. The association needs to be proved in a larger study.

    The elderly population has recently increased, and the need for cancer care and treatment for the elderly is likely to grow. We report on radiation therapy for cancer in elderly patients over 80 years of age. During the period from 1985 to 1996, 90 elderly patients (54 men, 36 women) aged over 80 years were treated with radiation therapy. Many patients had primary tumors of the esophagus, head and neck, and lungs, in that order of frequency. Fifty-seven percent of the patients were treated with radical radiotherapy, and 70% were treated with radiotherapy alone. The rate of completion of radiation therapy was 90%, and the response rate was 82%. Radiation therapy played an important role in the treatment of the patients over 80 years of age. The half of our patients had concurrent medical problems, and were dependent on their home physicians both before and after radiation therapy. We consider that radiation oncologists should make an effort to form a good relationship with home physicians. (author)

    Background As the population continues to age rapidly, clarifying the factors affecting the prognosis in very elderly stroke patients is essential to enhance the quality of their rehabilitation. Objectives To compare the functional recovery of elderly stroke patients classified into three age groups and to identify the predictors of functional recovery in the very elderly following acute inpatient rehabilitation. Methods Observational study: We collected data on 461 stroke patients in the neurology and neurosurgery ward and classified them into three age groups (65-74, 75-84, and ≥ 85 years). Functional recovery was compared among groups using the functional independence measure (FIM) at discharge and ADL recovery rate was compared using the Montebello rehabilitation factor score (MRFS). Multiple regression analysis was used to identify and compare the factors associated with functional recovery in each age group. Results Functional recovery in the ≥ 85 years group was lower than that in other age groups. Factors associated with activities of daily living (ADL) status (FIM at discharge) in the ≥ 85 years group were premorbid dependence (β = -0.183, p = 0.011), motor paralysis (β = -0.238, p = 0.001), and cognitive function (β = 0.586, p age increased. Factors associated with ADL recovery rates (MRFS) in the ≥ 85 years group were non-paretic limb function (β = -0.294, p = 0.004) and cognitive function (β = 0.201, p = 0.047). Conclusions This study identified the factors associated with functional recovery among very elderly stroke patients. Effective forms of rehabilitation for very elderly stroke patients that take these factors into consideration need to be investigated.

    The major complications of "treated" Human Immunodeficiency Virus (HIV) infection are cardiovascular disease, malignancy, renal disease, liver disease, bone disease, and perhaps neurological complications, which are phenomena of the normal aging process occurring at an earlier age in the HIV-infected population. The present study is aimed to explore protein carbonyl content as a biomarker for detecting oxidative DNA damage induced ART toxicity and/or accelerated aging in HIV/AIDS patients. To investigate the potential of carbonyl content as a biomarker for detecting oxidative Deoxyribonucleic acid (DNA) damage induced Antiretroviral Theraphy (ART) toxicity and/or accelerated aging in HIV/AIDS patients. In this case-control study a total 600 subjects were included. All subjects were randomly selected and grouped as HIV-negative (control group) (n=300), HIV-infected ART naive (n=100), HIV-infected on first line ART (n=100), and HIV-infected on second line ART (n=100). Seronegative control subjects were age- and sex-matched with the ART naive patients and the two other groups. Carbonyl protein was determined by the method described in Levine et al. DNA damage marker 8-OH-dG was determined using 8-hydroxy-2-deoxy Guanosine StressXpress ELA Kit by StressMarq Biosciences. Protein carbonyl content levels and oxidative DNA damage were significantly higher (paging in HIV/AIDS patients. Larger studies are warranted to elucidate the role of carbonyl content as a biomarker for premature aging in HIV/AIDS patients. Copyright © 2016 Sociedade Brasileira de Infectologia.

    Background and purpose: In this study, we investigated how often guidelines for radiation therapy in patients with breast cancer are not complied with, which patient group is mostly affected, and how this influences local recurrence. Patients and methods: All patients (n = 1,903) diagnosed between November 2003 and December 2008 with primary invasive or intraductal breast cancer in the interdisciplinary breast center of the Charite Hospital Berlin were included and followed for a median 2.18 years. Results: Patients who, in contrast to the recommendation of the interdisciplinary tumor board, did not undergo postoperative radiation experienced a fivefold higher local recurrence rate (p < 0.0005), corresponding to a 5-year locoregional recurrence-free survival of 74.5% in this group. The 5-year locoregional recurrence-free survival of patients following the recommendations was 93.3%. Guideline compliance was dependent on age of patients, acceptance of adjuvant hormonal treatment or chemotherapy, and increased diameter of the primary tumor. Multiple logistic regression analysis showed an association between compliance and age or hormonal therapy. Conclusion: In order to avoid local recurrence patients should be motivated to comply with guideline driven therapy. Since a higher number of local recurrences is observed in health services research compared to clinical research, studies on the value of adjuvant treatment following local recurrence should be performed.

    Previous studies show a limited alteration of gait at normal walking speed after spinal fusion surgery for adolescent idiopathic scoliosis (AIS), despite the presumed essential role of spinal mobility during gait. This study analyses how spinal fusion affects gait at more challenging walking speeds. More specifically, we investigated whether thoracic-pelvic rotations are reduced to a larger extent at higher gait speeds and whether compensatory mechanisms above and below the stiffened spine are present. 18 AIS patients underwent gait analysis at increasing walking speeds (0.45 to 2.22m/s) before and after spinal fusion. The range of motion (ROM) of the upper (thorax, thoracic-pelvic and pelvis) and lower body (hip, knee and ankle) was determined in all three planes. Spatiotemporal parameters of interest were stride length and cadence. Spinal fusion diminished transverse plane thoracic-pelvic ROM and this difference was more explicit at higher walking speeds. Transversal pelvis ROM was also decreased but this effect was not affected by speed. Lower body ROM, step length and cadence remained unaffected. Despite the reduction of upper body ROM after spine surgery during high speed gait, no altered spatiotemporal parameters or increased compensatory ROM above or below the fusion (i.e. in the shoulder girdle or lower extremities) was identified. Thus, it remains unclear how patients can cope so well with such major surgery. Future studies should focus on analyzing the kinematics of individual spinal levels above and below the fusion during gait to investigate possible compensatory mechanisms within the spine.

    Full Text Available A growing body of empirical research has confirmed an association between chronic pain and cognitive dysfunction. The aim of the present study was to determine whether cognitive function is affected in patients with a diagnosis of chronic neuropathic or radicular pain relative to healthy control participants matched by age, gender, and years of education. We also examined the interaction of pain with age in terms of cognitive performance. Some limitations of previous clinical research investigating the effects of chronic pain on cognitive function include differences in the pain and cognitive scale materials used, and the heterogeneity of patient participants, both in terms of their demographics and pathological conditions. To address these potential confounds, we have used a relatively homogenous patient group and included both experimental and statistical controls. We have also specifically investigated the interaction effect of pain and age on cognitive performance. Patients (n = 38 and controls (n = 38 were administered a battery of cognitive tests measuring IQ, spatial and verbal memory, attention, and executive function. Educational level, depressive symptoms, and state anxiety were assessed as were medication usage, caffeine, and nicotine consumption to control for possible confounding effects. Both the level of depressive symptoms and the state anxiety score were higher in chronic pain patients than in matched control participants. Chronic pain patients had a lower estimated IQ than controls, and showed impairments on measures of spatial and verbal memory. Attentional responding was altered in the patient group, possibly indicative of impaired inhibitory control. There were significant interactions between chronic pain condition and age on a number of cognitive outcome variables, such that older patients with chronic pain were more impaired than both age-matched controls and younger patients with chronic pain. Chronic pain did not appear

    Endoscopic third ventriculostomy (ETV) has been accepted as the procedure of choice for the treatment of obstructive hydrocephalus in children and adults. The role and outcome of this procedure in the elderly has not been evaluated yet. Over an 11-year interval we retrospectively analyzed data of patients, 65+ years of age, who underwent ETV in our center. Success of the procedure was assessed in terms of symptom relief and/or elimination of the need for shunting. Additionally pre- and postoperative ventricular volumes were estimated using Evan's index (Ei) and fronto-occipital horn ratio (FOR). In our analysis we compared the results of the elderly patients with those of the pediatric and adult age groups treated in our center. We obtained data of 16 elderly cases (11 males, 5 females), mean age 72.8 years (66-83 years) out of the 91 patients treated with ETV in total. The success rate was 75% in this age group; mean follow-up 18.4 months (2-55 months). In 10 patients a mass lesion was the underlying cause of hydrocephalus. Mean ventricular size reduction was 18% and 13.5% (Ei and FOR) in the success group vs. 7.6% and 6.2% in the failure group. Three out of four patients who had shunting pre-EVT, became shunt independent post-operatively. The presence of flow void over the stoma was 100% correlated with success. All 7 patients with a primary or metastatic brain tumor were able to receive radiation therapy. Also in elderly, ETV is a safe and efficient procedure, with success rates similar to the younger population. Further research is required to set up a prognostic scoring system for this age group.

    Postconditioning can affect the infarct size in acute myocardial infarction (AMI). However, few studies show an effect of different postconditioning cycles on AMI aged patients. This study sought to assess the effect of different postconditioning cycles on prognosis in aged patients with AMI who underwent primary percutaneous coronary intervention (PCI). 74 aged patients were randomly assigned to three groups. Control group; PC-1 group accepted postconditioning 4 cycles of 30 s inflation and 30 s deflation; PC-2 group accepted postconditioning 4 cycles of 60 s. Creatine kinase MB (CK-MB), troponin I (cTnI), high-sensitive C-reactive protein (hs-CRP) and corrected Thrombolysis in Myocardial Infarction (TIMI) frame counts (CTFC) were analyzed before andafter treatment. All patients received an echocardiographic examination for whole heart function, wall motion score index (WMSI) and single-photon emission computed tomography (SPECT) examination at 7 days and 6 months after treatment. S: The peak of CK-MB, postoperative 72 h cTnI and CTFC were significantly attenuated by postconditioning when compared with the control group. The hs-CRP of the postconditioning group was lower than the control group 24 h postoperative. No difference was observed between PC-1 and PC-2 group about the effect described above. At 7 days, heart function in the postconditioning group was improved when compared with the control group. At 6 months, the WMSI and SPECT score significantly reduced in the PC-2 group compared with the control and PC-1 groups, but there was no difference among the three groups about echo data except the left ventricular end-systolic diameter. Postconditioning is significantly beneficial to prognosis in aged patients with AMI. The cardiac protective effect of 4 cycles of 60 s procedure was observed in WMSI and SPECT. It is favorable to implement this procedure in aged patients with AMI in clinic.

    To (1) report clinical outcomes, complication rates, and total hip arthroplasty (THA) conversion rates for patients age 40 or older who underwent hip arthroscopy, and (2) report any age-related predictors of outcome identified in the literature. MEDLINE, EMBASE, and PubMed were searched for relevant studies and pertinent data were abstracted from eligible studies. No meta-analysis was performed because of heterogeneity amongst studies. Seventeen studies were included in this review comprising 16,327 patients, including 9,954 patients age 40 or older. All studies reported statistically significant improvements in outcomes after hip arthroscopy for femoral osteochondroplasty, labral repair, or unspecified indications. In patients 40 or older who underwent labral debridement, these improvements were not clinically significant. Obesity and osteoarthritic changes predicted poorer outcomes. Only 1 of 3 studies directly comparing the 2 groups found that patients 40 or older had a significantly less improvement in a standardized hip outcome score than patients under 40 after hip arthroscopy, but all found that patients 40 or older had significantly higher rates of THA conversion. The rate of conversion to THA was 18.1% for patients 40 or older, 23.1% for patients over 50, and 25.2% for patients over 60 with a mean of 25.0 months to THA. Indications for hip arthroscopy including femoral osteochondroplasty and labral repair resulted in clinically significant improvements in patients 40 or older in most research studies examined in this review, whereas labral debridement did not produce clinically significant improvements postoperatively in the same studies. In these studies, the rate of conversion to THA is higher than in patients under 40 and increases with each decade of life, with many individual studies showing a significant increase in the rate of THA conversion. Hip arthroscopy may be suitable for some patients 40 or older, but patient selection is key and patients

    Increased age is strongly associated with anorexia and protein-energy wasting (PEW) in maintenance hemodialysis (MHD) population. We hypothesized that the association of obestatin, a recently discovered anorexigenic gut hormone, with appetite and nutritional status differs by age groups. We performed a cross-sectional study on 261MHD patients. Obestatin, acyl-ghrelin, markers of inflammation (CRP, IL-6, TNF-α) and nutrition (self-reported appetite, dietary intake, biochemical nutritional parameters, and body composition) were measured. Obestatin was associated with appetite in multivariate analyses even after controlling for such confounders as lean body mass (LBM), IL-6 and acyl-ghrelin in patients younger than 71 years. For each ng/ml increase in obestatin levels, the odds for diminished appetite was 0.75 (95% CI: 0.59-0.96). However, these associations were not observed in patients 71 years and older. Multivariable logistic regression models (including appetite) also showed increasing odds for PEW (defined by ESPEN consensus-based criteria for the diagnosis of malnutrition) across increasing serum obestatin levels (OR: 1.51, 95% CI: 1.05-2.18) in patients 71 years and older. However, after lean body mass (LBM) was added to this model, the association between obestatin and malnutrition was abolished (OR: 1.26, 95% CI: 0.83-1.91). The association between serum obestatin, appetite and PEW differs depending on age in MHD patients. A positive link with appetite exists in patients younger than 71 years, whereas this relationship disappears by the age of 71. In older MHD patients, obestatin is associated with PEW through mechanisms related to LBM, but not to appetite.

  12. Does the Age of Donor Kidneys Affect Nocturnal Polyuria in Patients With Successful Real Transplantation?

    We investigated whether the age of donor kidneys influences the incidence of nocturnal polyuria in patients with successful renal transplantation (RTX). Eighty-five patients (45 men and 40 women) undergoing RTX (median age, 47 years) were included in this study. Twenty-four-hour bladder diaries were kept for 3 days, and nocturnal polyuria was defined as a nocturnal polyuria index (nocturnal urine volume/24-hour urine volume) of >0.33. Risk factors for nocturnal polyuria were analyzed in patients with RTX by means of the Mann-Whitney U test, χ 2 test, and a logistic regression analysis. End-stage renal disease (ESRD) developed from diabetes mellitus in 16 patients (19%). Sixty-five patients (76%) received pre-transplant dialysis, with a median duration of 5 years. The median serum creatinine level and body mass index at the most recent visit were 1.2 mg/dL and 21.2 kg/m 2 , respectively. On the basis of the 24-hour bladder diaries, nocturnal polyuria was identified in 48 patients (56%). A logistic regression analysis revealed that diabetes mellitus as the original disease for ESRD was the only risk factor for nocturnal polyuria (odds ratio, 8.95; 95% confidence interval, 2.01-65.3; P = .0028). The age of donor kidneys at examination did not affect the incidence of nocturnal polyuria (P = .9402). Nocturnal polyuria was not uncommon in patients with successful RTX. Diabetes mellitus as the original disease for ESRD was the only risk factor for nocturnal polyuria, whereas the age of donor kidneys at examination did not affect the incidence of nocturnal polyuria. Thus, nocturnal polyuria is caused by recipient factors but not donor factors. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available PURPOSE - To evaluate diastolic dysfunction (DD in essential hypertension and the influence of age and cardiac geometry on this parameter. METHODS - Four hundred sixty essential hypertensive patients (HT underwent Doppler echocardiography to obtain E/A wave ratio (E/A, atrial deceleration time (ADT, and isovolumetric relaxation time (IRT. All patients were grouped according to cardiac geometric patterns (NG - normal geometry; CR - concentric remodeling; CH- concentric hypertrophy; EH - eccentric hypertrophy and to age (60 years. One hundred six normotensives (NT persons were also evaluated. RESULTS - A worsening of diastolic function in the HT compared with the NT, including HT with NG (E/A: NT - 1.38±0.03 vs HT - 1.27±0.02, p<0.01, was observed. A higher prevalence of DD occurred parallel to age and cardiac geometry also in the prehypertrophic groups (CR. Multiple regression analysis identified age as the most important predictor of DD (r²=0.30, p<0.01. CONCLUSION - DD was prevalent in this hypertensive population, being highly affected by age and less by heart structural parameters. DD is observed in incipient stages of hypertensive heart disease, and thus its early detection may help in the risk stratification of hypertensive patients.

    Rationale Chronic obstructive pulmonary disease (COPD) is often associated with age-related systemic abnormalities that adversely affect the prognosis. Whether these manifestations are linked to the lung alterations or are independent complications of smoking remains unclear. Objectives To look for aging-related systemic manifestations and telomere shortening in COPD patients and smokers with minor lung destruction responsible for a decline in the diffusing capacity for carbon monoxide (DLCO) corrected for alveolar volume (KCO). Methods Cross-sectional study in 301 individuals (100 with COPD, 100 smokers without COPD, and 101 nonsmokers without COPD). Measurements and Main Results Compared to control smokers, patients with COPD had higher aortic pulse-wave velocity (PWV), lower bone mineral density (BMD) and appendicular skeletal muscle mass index (ASMMI), and shorter telomere length (TL). Insulin resistance (HOMA-IR) and glomerular filtration rate (GFR) were similar between control smokers and COPD patients. Smokers did not differ from nonsmokers for any of these parameters. However, smokers with normal spirometry but low KCO had lower ASMMI values compared to those with normal KCO. Moreover, female smokers with low KCO, had lower BMD and shorter TL compared to those with normal KCO. Conclusions Aging-related abnormalities in patients with COPD are also found in smokers with minor lung dysfunction manifesting as a KCO decrease. Decreased KCO might be useful, particularly among women, for identifying smokers at high risk for aging-related systemic manifestations and telomere shortening. PMID:25785739

    Developmental typologies regarding age of onset of violence and offending have not routinely taken account of the role of serious mental illness (SMI), and whether age of onset of offending in relation to onset of illness impacts on the manifestation of offending over the life course. To test whether forensic psychiatric patients can be classified according to age of onset of SMI and offending, and, if so, whether subtypes differ by sex. Details of all 511 patients enrolled into a large forensic mental health service in Ontario, Canada, in 2011 or 2012 were collected from records. A latent profile analysis supported a 2-class solution in both men and women. External validation of the classes demonstrated that those with a younger age onset of serious mental illness and offending were characterised by higher levels of static risk factors and criminogenic need than those whose involvement in both mental health and criminal justice systems was delayed to later life. Our findings present a new perspective on life course trajectories of offenders with SMI. While analyses identified just two distinct age-of-onset groups, in both the illness preceded the offending. The fact that our sample was entirely drawn from those hospitalised may have introduced a selection bias for those whose illness precedes offending, but findings underscore the complexity and level of need among those with a younger age of onset.

    Objective: To investigate the effect of Meek skin grafting on patients with extensive deep burn at different age groups. Methods: Eighty-four patients with extensive deep burns conforming to the study criteria were hospitalized in our unit from April 2011 to April 2015. Patients were divided into children group (C, with age less than 12 years old), young and middle-aged group (YM, with age more than 18 years and less than 50 years old), and old age group (O, with age more than 55 years old) according to age, with 28 patients in each group. All patients received Meek skin grafting treatment. The use of autologous skin area, operation time, wound healing time, and hospitalization time were recorded. The survival rate of skin graft on post operation day 7, complete wound healing rate in post treatment week 2, and the mortality were calculated. Data were processed with one-way analysis of variance, t test, and χ (2) test. Results: The use of autologous skin area of patients in group C was (5.1±1.0)% total body surface area (TBSA), significantly less than (8.3±1.0)%TBSA and (8.3±1.4)%TBSA in groups YM and O, respectively (with t values 32.900 and 52.624, respectively, P values below 0.05). The operation time, wound healing time, and hospitalization time of patients in group C were (1.368±0.562) h, (9.6±0.6) and (32±11) d, significantly shorter than those in group YM [(3.235±0.011) h, (16.9±2.6) and (48±12) d, respectively] and group O [(3.692±0.481) h, (17.3±2.6) and (46±13) d, respectively, with t values from 4.350 to 21.160, P values below 0.05]. The survival rate of skin graft of patients on post operation day 7 in group C was (92±15)%, significantly higher than (81±10)% and (72±12)% in groups YM and O, respectively (with t values 5.509 and 3.229, respectively, P values below 0.05). The above indexes in groups YM and O were similar (with t values from 0.576 to 22.958, P values above 0.05). Complete wound healing rate in post treatment week 2 and the

    Full Text Available Research objective was investigating arterial wall stiffness in patients with hypertension at young age and assessing the relationship between subclinical target organs damage and ambulatory blood pressure monitoring (ABPM parameters. 30 male patients aged 18-35 years with essential hypertension stage I and II, hypertension 1 and 2nd grade were surveyed. The examination included general clinical methods, echocardiography, ABPM and suprasystolic sfigmography. It was found that the pulse wave velocity (PWVao (r = 0,557 p <0,01, central aortic blood pressure (SBPao (r = 0,492 p <0,01 and augmentation index (AIxao (r = 0,489 p <0.01 significantly increased with the pa¬tients’ age. Abdominal obesity (r = 0,566 p <0,01 and BMI (r = 0,599 p <0,01 impacted on the PWVao acceleration. Increasing of the left ventricular mass index (LVMI is highly associated with SBPao (r = 0,506 p <0,05 and PWVao (r = 0,434 p <0,05. According to ABPM the most significant correlation with arterial wall stiffness parameters demon¬strated diastolic blood pressure (DBP daytime level (AIxao (r = 0,418 p <0,01, with PWVao (r = 0,699 p <0.01 and SBPao (r = 0,695 p <0,01. Thus, age, excessive body weight and obesity should be considered as unfavorable factors that worsen arterial wall stiffness in patients with hypertension at the age before 35 years. Increase of DBP levels especially during the day causes maximum negative impact on the arterial wall stiffness parameters according to ABPM. Increased SBPao and PWVao in patients with hypertension at a young age are associated with increased left ventricular mass index.

    The median age of patients with Ewing sarcoma (EwS) at diagnosis is around 14-15 years. Older age is associated with a worse outcome. The correlation of age at diagnosis on sites of disease has not been fully described. The goal of this study was to evaluate the differences in sites of primary tumor and metastatic tumor involvement according to age groups. EwS data from the Gesellschaft für Pädiatrische Onkologie und Hämatology (GPOH) database of the Cooperative Ewing Sarcoma Study (CESS) 81/86 and the European Intergroup Cooperative Ewing's Sarcoma Study EICESS 92 and the EUROpean Ewing tumor Working Initiative of National Groups-99-Protocol (EURO-E.W.I.N.G.-99) study were analyzed. Patient and tumor characteristics were evaluated statistically using chi square tests. The study population included 2,635 patients with bone EwS. Sites of primary and metastatic tumors differed according to the age groups of young children (0-9 years), early adolescence (10-14 years), late adolescence (15-19 years), young adults (20-24 years), and adults (more than 24 years). Young children demonstrated the most striking differences in site of disease with a lower proportion of pelvic primary and axial tumors. They presented less often with metastatic disease at diagnosis. Site of primary and metastatic tumor involvement in EwS differs according to patient age. The biological and developmental etiology for these differences requires further investigations. © 2018 Wiley Periodicals, Inc.

    Full Text Available Colorectal cancer screening is underutilized, resulting in preventable morbidity and mortality. In the present study, age-related and other disparities associated with physicians’ delivery of colorectal cancer screening recommendations were examined. The present cross-sectional study included 43 physicians and 618 of their patients, aged 50 to 80 years, without past or present colorectal cancer. Of the 285 screen-eligible patients, 45% received a recommendation. Multivariate analyses revealed that, compared with younger nonde-pressed patients, older depressed patients were less likely to receive fecal occult blood test recommendations, compared with no recommendation (OR=0.31, 95% CI 0.09 to 1.02, as well as less likely to receive colonoscopy recommendations, compared with no recommendation (OR=0.14; 95% CI 0.03 to 0.66. Comorbidity and marital status were associated with delivery of fecal occult blood test and colonoscopy recommendations, respectively, compared with no recommendation. In summary, patient age and other characteristics appeared to influence physicians’ delivery of colorectal cancer screening and choice of modality.

    Age-related macular degeneration (AMD) is a leading cause of blindness over the age of 50 in western countries. People with AMD are suffering from serious vision-related disability and their social life is compromised. The aim of our study was to assess quality of life (QoL) in patients with exudative AMD. The study group was 100 patients treated for AMD, the control group were 30 age and sex matched subjects without ophthalmic disorders. Patients were treated with anti-VEGF therapy, by means of National Eye Institute Visual Function Questionnaire (NEI VFQ-25). As well as visual function, the NEI-VFQ investigates social functioning, mental health and dependency. There was statistically significant difference in QoL overall score between study group and control group. Patients with AMD obtained 51.1 (+/- 20.5 ) overall score, control group reached 83.7 (+/- 11.7) overall score, p = 0.001. Detailed analysis of study group revealed low acceptance of the disease and strong dependency. QoL in patients with AMD assessed with NEI VFQ-25, is significantly impaired. Low quality of life and difficulties in performing daily activities point at the need of formal psychological and social care.

    Younger age and female sex are both associated with greater mental stress in the general population, but limited data exist on the status of perceived stress in young and middle-aged patients presenting with acute myocardial infarction. We examined sex difference in stress, contributing factors to this difference, and whether this difference helps explain sex-based disparities in 1-month recovery using data from 3572 patients with acute myocardial infarction (2397 women and 1175 men) 18 to 55 years of age. The average score of the 14-item Perceived Stress Scale at baseline was 23.4 for men and 27.0 for women (Pstress in women was explained largely by sex differences in comorbidities, physical and mental health status, intrafamily conflict, caregiving demands, and financial hardship. After adjustment for demographic and clinical characteristics, women had worse recovery than men at 1 month after acute myocardial infarction, with mean differences in improvement score between women and men ranging from -0.04 for EuroQol utility index to -3.96 for angina-related quality of life (Pstress reduced these sex-based differences in recovery to -0.03 to -3.63, which, however, remained statistically significant (Pstress at baseline was associated with significantly worse recovery in angina-specific and overall quality of life, as well as mental health status. The effect of baseline stress on recovery did not vary between men and women. Among young and middle-aged patients, higher stress at baseline is associated with worse recovery in multiple health outcomes after acute myocardial infarction. Women perceive greater psychological stress than men at baseline, which partially explains women's worse recovery. © 2015 American Heart Association, Inc.

    Cleft palate is one of the most common congenital craniofacial deformities. Otitis media with effusion (OME) is a middle ear disease having a prevalence of almost 90% in patients with cleft palates. Tympanometry is a fast, safe, non-invasive, and easy tool for diagnosing middle ear disease qualitatively and quantitatively. Studies have been conducted using tympanometry to detect middle ear conditions in patients with cleft palates, but no research has studied tympanogram findings in patients with cleft palates in Indonesia. The aim of this study is to determine the tympanogram findings in Indonesian children aged six months to seven years with cleft palates. This is a cross-sectional study of 30 patients (17 males and 13 females) with Veau classification of palatal clefts aged six months to seven years (median 26.5 months) who underwent tympanometry examinations using a 226 Hztympanometer. Tympanograms were classified using the Jerger/Liden classification. Examinations of 58 ears found that type B tympanograms occurred most frequently (70.7%). The quantitative values of tympanometry analyzed included SAA (0.1-0.2 cm3), TPP value (-197.2-(-146.8 daPa)), Vec value (0.5-0.6 cm3), and gradient value (0.03-0.07 cm3). Using the Fisher test, a significant relationship was found between age and type of tympanogram (p = 0.0039) with the risk of type B and C tympanograms in infants (6-60 months) as high as 4.8 times that of children without cleft palates. The type B tympanogram was most frequently seen in patients with cleft palates aged six months to seven years old with the quantitative values of tympanometry lower than the normal values. Therefore, there was a significant difference in the type of tympanogram seen with age.

    To determine the frequency and quality of religious history taking of patients by clinicians working in an old age psychiatry service. A retrospective audit of 80 randomised patient files from the Koropiko Mental Health Services for Older People (MHSOP) in Middlemore Hospital, Auckland, New Zealand. A total of 66 clinical records were available for analysis. A religious history was taken in 33/66 (50%) patients. However, when such histories were evaluated using the FICA assessment tool, only 10/33 (30.3%) histories contained detailed information regarding the patient's religiousness. The infrequency and low quality of religious histories discovered in this audit suggest that clinicians need more training in taking a religious history from patients.

    Full Text Available Huntington’s disease (HD is an autosomal dominant neurodegenerative disorder. The causative mutation is an expansion of more than 36 CAG repeats in the first exon of IT15 gene. Many studies have shown that the IT15 interacts with several modifier genes to regulate the age at onset (AO of HD. Our study aims to investigate the implication of CAG expansion and 9 modifiers in the age at onset variance of 15 HD Tunisian patients and to establish the correlation between these modifiers genes and the AO of this disease. Despite the small number of studied patients, this report consists of the first North African study in Huntington disease patients. Our results approve a specific effect of modifiers genes in each population.

    Renal failure (RF) represents a major postoperative complication for elderly patients undergoing cardiac surgery. This observational cohort study examines effects of preoperative use of renin-angiotensin system (RAS) inhibitors on postoperative renal failure in aging patients undergoing cardiac surgery. We retrospectively analyzed a cohort of 1287 patients who underwent cardiac surgery at this institution (2003-2007). The patients included were ≥65 years old, scheduled for elective cardiac surgery, and without preexisting RF (defined by the criteria of the Society of Thoracic Surgeons as described in Method). Of all patients evaluated, 346 patients met the inclusion criteria and were divided into two groups: using (n = 122) or not using (n = 224) preoperative RAS inhibitors. A comparison of the two groups showed no significant differences in baseline parameters, including creatinine clearance, body mass index, history of diabetes and smoking, preoperative medicines (except that more patients with RAS inhibitors had a history of hypertension or congestive heart failure, fewer RAS inhibitor patients had chronic lung disease), in intraoperative perfusion and aortic cross-clamp time, and in postoperative complications and 30-d mortality. Multivariate logistic regression analysis demonstrated, however, that preoperative RAS inhibitors significantly and independently reduced the incidence of postoperative RF in the patients undergoing cardiac surgery compared with those not taking RAS inhibitors: 1.6% versus 7.6%, yielding an odds ratio of 0.19 (95 % CI 0.04-0.84, P = 0.029). Preoperative RAS inhibitors may have significant renoprotective effects for aging patients undergoing elective cardiac surgery. Copyright © 2011 Elsevier Inc. All rights reserved.

    Full Text Available Introduction. According to the level of intraocular pressure (IOP, open angle glaucoma is divided into high tension glaucoma (HTG and normal tension glaucoma (NTG. Objective. To determine if there are differences in the distribution of patients by age and sex between NTG and HTG. Methods. Our prospective study included 30 patients with NTG and 30 with HTG. A complete eye examination was performed. The examination included measuring of intraocular pressure by Goldmann applanation tonometry, examination of optic disc head by indirect ophthalmoscopy with Volk 90 D lens and visual field examination using the Octopus program. Results. The average damage of visual field in the group of patients with NTG was 8.14±4.43 dB, while in the group with HTG it was 7.40±2.84 dB (p>0.05. The average age of the group of patients with NTG was 66±11.58 years, while among those with HTG the average age was 59.7±11.63 years (p<0.01. Among the patients with NTG there were three times more women than men (χ2=9.124; p<0.01, while in the group of patients with HTG there were more men than women, but without statistically significant difference between the tested groups (χ2=1.851; p>0.05. Conclusion. Open angle glaucoma is a disease of elderly population. According to our results, risk factors for this disease can be age and sex. NTG is more frequently present than HTG among elderly population and females.

  17. Differences in selected medical care parameters in rheumatic disease ward patients of different ages of life

    Full Text Available Introduction : Rheumatic diseases are becoming more and more common in Poland with the ageing of the population. Nearly 18% of the total hospital admissions in Poland result from rheumatic diseases, which was equivalent to 350 thousand cases in the year 2008. These diseases tend to last for many decades, decreasing both the quality of life and income of the patients as well as increasing the medical institutions’ workload and society’s financial burden. The aim of the study was to determine whether the medical care parameters in a rheumatic disease hospital ward show any significant differences among different patient age groups – especially such that would support taking them into account as a basis for adjusting the financial coverage level of medical services. Material and methods : Data on hospitalizations at the Rheumatic Diseases Ward of Wroclaw University Hospital in Wroclaw in the years 2009–2015 were analyzed, taking into account the age groups, number of hospital admissions, their duration and causes. Relevant statistical data analysis was performed. Discussion: The study revealed that the number of old patients hospitalized at the rheumatic diseases ward increased over the last 6 years and that such statistically significant differences do exist: on average the old patients not only tend to stay much longer at the hospital, but also suffer from a different and more diverse spectrum of diseases in comparison to their younger counterparts. Conclusions : The detected differences in medical care parameters support the need for more individualized medical care and increased cost of the hospital stay in the case of older patients. Consequently, those factors justify the necessity to increase the value of medical services in the case of old patients, possibly also taking into account the variation between age subgroups.

    Full Text Available Cold Wind Cave, located at elevations ranging between 1,600 and 1,700 m a. s. l. in the main range of the Nízke Tatry Mountains(Slovakia, is linked in origin with the adjacent Dead Bats Cave. Together, these caves form a major cave system located within anarrow tectonic slice of Triassic sediments. Both caves have undergone complex multiphase development. A system of sub-horizontalcave levels characterized by large, tunnel-like corridors was formed during the Tertiary, when elevation differences surroundingthe cave were less pronounced than today. The central part of the Nízke Tatry Mountains, together with the cave systems, wasuplifted during the Neogene and Lower Pleistocene, which changed the drainage pattern of the area completely. The formation ofnumerous steep-sloped vadose channels and widespread cave roof frost shattering characterized cave development throughout theQuaternary.In the Cold Wind Cave, extensive accumulations of loose, morphologically variable crystal aggregates of secondary cave carbonateranging in size between less than 1 mm to about 35 mm was found on the surface of fallen limestone blocks. Based on the C andO stable isotope compositions of the carbonate (δ13C: 0.72 to 6.34 ‰, δ18O: –22.61 to –13.68 ‰ V-PDB and the negative relationbetween δ13C and δ18O, the carbonate crystal aggregates are interpreted as being cryogenic cave carbonate (CCC. Publishedmodels suggest the formation of CCC in slowly freezing water pools, probably on the surface of cave ice, most probably duringtransitions from stadials to interstadials. Though the formation of these carbonates is likely one of the youngest events in thesequence of formation of cave sediments of the studied caves, the 230Th/234U ages of three samples (79.7±2.3, 104.0±2.9, and180.0±6.3 ka are the oldest so far obtained for CCC in Central Europe. This is the first description of CCC formation in one caveduring two glacial periods (Saalian and Weichselian.

    This study was designed to elucidate the dose-response relationships for life-shortening and tumorigenic effect in the dose range below 1 Gy of gamma rays delivered during the infant period. Female B6C3F 1 mice were irradiated with 0.10, 0.48 or 0.95 Gy at 7 days of age. All irradiated mice were allowed to live out their entire life span together with a simultaneously ongoing control group under a specific pathogen-free condition. Shortening of the mean life span was 1.58% in mice irradiated with 0.10 Gy, which was statistically significant. The coefficient of the linear dose-response relationship for life-shortening was 11.21% Gy -1 . The attributable death fraction for all causes of death in 0.10 Gy group reached 0.092. The excess relative risk for death rate from all causes was 0.102 in the group irradiated with 0.10 Gy. The coefficient of the linear dose-response relationship of the excess relative risk for death rate from all causes was 1.30 Gy -1 . The mean number of types of solid tumors at the time of death in mice irradiated with 0.10 Gy was distinctly larger than that in the control group. The excess relative risk for death rate from solid tumors was 0.45 in mice irradiated with 0.10 Gy. The coefficient of the linear dose-response relationship of excess relative risk for death rate from solid tumors was 4.52 Gy -1 . Increase in incidences of the pituitary, ovarian and adrenal tumors was observed in mice irradiated with 0.10 Gy. The results of the present study showed that infant mice are susceptible to solid tumor induction, especially of the endocrine organs. (author)

  20. Accelerated aging in schizophrenia patients: the potential role of oxidative stress.

    Okusaga, Olaoluwa O

    2014-08-01

    Several lines of evidence suggest that schizophrenia, a severe mental illness characterized by delusions, hallucinations and thought disorder is associated with accelerated aging. The free radical (oxidative stress) theory of aging assumes that aging occurs as a result of damage to cell constituents and connective tissues by free radicals arising from oxygen-associated reactions. Schizophrenia has been associated with oxidative stress and chronic inflammation, both of which also appear to reciprocally induce each other in a positive feedback manner. The buildup of damaged macromolecules due to increased oxidative stress and failure of protein repair and maintenance systems is an indicator of aging both at the cellular and organismal level. When compared with age-matched healthy controls, schizophrenia patients have higher levels of markers of oxidative cellular damage such as protein carbonyls, products of lipid peroxidation and DNA hydroxylation. Potential confounders such as antipsychotic medication, smoking, socio-economic status and unhealthy lifestyle make it impossible to solely attribute the earlier onset of aging-related changes or oxidative stress to having a diagnosis of schizophrenia. Regardless of whether oxidative stress can be attributed solely to a diagnosis of schizophrenia or whether it is due to other factors associated with schizophrenia, the available evidence is in support of increased oxidative stress-induced cellular damage of macromolecules which may play a role in the phenomenon of accelerated aging presumed to be associated with schizophrenia.

    Purpose: In an aging society, many senior citizens want less invasive treatment because of potential medical complications. The National Institute of Radiological Sciences has started to treat stage I lung cancer with single-fraction carbon-ion radiation therapy (CIRT) as a dose escalation prospective phase 1/2 trial. We evaluated the efficacy and safety of CIRT for patients 80 years of age and older, undergoing single-fraction CIRT. Methods and Materials: Peripheral non-small cell lung cancer patients who were treated with single-fraction CIRT were prospectively followed. We analyzed the data from among these patients 80 years of age and older. Results: There were 70 patients. Median age was 83 years (range: 80-89) and median follow-up period was 42.7 months (range: 12-128 months). Three-year local control, cause-specific survival, and overall survival rates were 88.0%, 81.6%, and 72.4%, respectively. Five-year local control, cause-specific survival, and overall survival rates were 85.8%, 64.9%, and 39.7%, respectively. There were no adverse effects higher than grade 2 either in the acute or late phase in terms of skin and lung. Analgesic agents were necessary for only 5 patients (7.1%), to relieve muscular or rib fracture pain caused by irradiation. Conclusions: Single-fraction CIRT was low-risk and effective, even for the elderly.

    The peak incidence of Ewing sarcoma (EWS) is in adolescence, with little known about patients who are ≥40 years at diagnosis. We describe the clinical characteristics and survival of this rare group. This retrospective cohort study utilized the Surveillance Epidemiology and End Results database. 2780 patients were identified; including 383 patients diagnosed ≥40 years. Patient characteristics between age groups were compared using chi-squared tests. Survival from diagnosis to death was estimated via Kaplan-Meier methods, compared with log-rank tests, and modeled using multivariable Cox methods. A competing risks analysis was performed to evaluate death due to cancer. Patients ≥40 years of age were more likely to have extra-skeletal tumors (66.1% vs. 31.7%; p extra-skeletal tumors, metastatic disease, and axial primary tumors suggesting a difference in tumor biology. Independent of differences in these characteristics, older patients also have a lower survival rate. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available The sociomedical significance of osteoporosis is determined by its sequels (vertebral and peripheral skeletal fractures that are responsible for high mortality and disability rates among persons in the old age group and accordingly for high material costs in the health care system.Objective: to study sociomedical sequels and quality of life in patients with proximal femoral fractures in the old age group.Subjects and methods. 956 patients with osteoporotic fractures were followed up. Major social sequels were traced in the patients 6, 12, and 24 months after femur fractures in relation to treatment options.Results. There were 10 (8.0% and 78 (66.7% bedridden patients in the surgical and medical treatment groups, respectively. Twenty four months after fracture, recovery of function was noted in 72 (57.6% and 32 (27.35% patients receiving surgical and medical treatment, respectively.Conclusion. The findings suggest that immediate and late sequels in patients with proximal femoral fractures depend on a treatment option.

    Full Text Available BACKGROUND: Metabolic syndrome and/or its components have been demonstrated to be risk factors for several cancers. They are also found to influence survival in breast, colon and prostate cancer, but the prognostic value of metabolic syndrome in gastric cancer has not been investigated. METHODS: Clinical data and pre-treatment information of metabolic syndrome of 587 patients diagnosed with early stage gastric cancer were retrospectively collected. The associations of metabolic syndrome and/or its components with clinical characteristics and overall survival in early stage gastric cancer were analyzed. RESULTS: Metabolic syndrome was identified to be associated with a higher tumor cell differentiation (P=0.036. Metabolic syndrome was also demonstrated to be a significant and independent predictor for better survival in patients aged >50 years old (P=0.009 in multivariate analysis or patients with proximal gastric cancer (P=0.047 in multivariate analysis. No association was found between single metabolic syndrome component and overall survival in early stage gastric cancer. In addition, patients with hypertension might have a trend of better survival through a good control of blood pressure (P=0.052 in univariate analysis. CONCLUSIONS: Metabolic syndrome was associated with a better tumor cell differentiation in patients with early stage gastric cancer. Moreover, metabolic syndrome was a significant and independent predictor for better survival in patients with old age or proximal tumors.

The purpose of present study was investigating the presence of any apraxic disorder in patients with senile dementia of Alzheimer type (SDAT and comparison with normal aged people. Materials & Methods: In this case–control and analytical study 14 SDAT patients were compared with 20 normal ageing people that they were matched with patients according to age and education. Patients were selected from Iranian Alzheimer Association clients with psychiatrist diagnostic confirmation and MMSE scores between 15-27 and compared with controls with MMSE scores between 25-30. Apraxia Test was administered on both groups. The Test included 4 subtests: conceptual movements gestured conceptual movements, oral and respiratory movements & pantomime of movements of object manipulations. Data was analyzed by using Kolmogoroff – Smirnoff test, Man – Witney, T-test for independent groups and pearsonian correlation coefficient. Results: Findings showed that apraxia scores were significantly (P<0/001 different between groups so that (SDAT patients were diagnosed as apraxic and controls were not. Besides, comparison of subtests scores of (SDAT patients revealed that conceptual movements scores were significantly (P<0/001 less than the other subtests (more apraxic and oral and respiratory movements scores were significantly (P<0/001 higher than the other subtests (less apraxic. Conclusion: Apraxia could be considered as one of the neuropsychological signs early in the disease development. It can be applied complementarily for differential diagnosis. Also apraxia subgroup scoring could be used for apraxia categorization, understanding observed disorders and determining possible rehabilitation ways.

    Objective: To determine serum lipids in patients with age related macular degeneration from Pakistani population. Methods: The study was a cross sectional, randomized and case-control. Selected subjects ages were >50 years and were normotensive, non-diabetic with no family history of any such disease and no complication of posterior ocular chamber other than age related macular degeneration (AMD). Controls were age matched healthy individuals with no symptoms of AMD. Diagnosis of AMD was done through conventional diagnostic techniques by professional ophthalmologists. Serum samples were analyzed for total cholesterol, triglycerides, LDL and HDL using commercially available kits. Data were compared with Student's t-test. Pearson correlation was calculated for relationship between different parameters. P<0.05 was considered significant. Results: Compared to controls, AMD patients had significantly greater total cholesterol concentration (p<0.041), and power HDL/LDL ratio (p<0.038), while serum triglycerides, HDL and LDL were non-significantly different from control subjects. Total cholesterol in AMD patients was significantly correlated with TG, LDL and HDL (p<0.0001). Conclusion: The study indicates that high cholesterol might be a predictor of AMD and can be a diagnostic parameter. (author)

    Dysphagia in elderly patients has a major effect on nutrition and quality of life (QOL). Although several studies have shown that aging itself is associated with changes in esophageal motility, the impact of these changes on dysphagia symptoms and QOL is unknown. This study assessed the manometric diagnoses of elderly patients with dysphagia compared with diagnoses in younger counterparts. Participants included 116 consecutive patients examined for dysphagia from 2007 to 2014. We divided patients into three groups by age: Group A, 66 years and older (24 men, 23 women); Group B, 45-65 years (18 men, 24 women); and Group C, 44 years and younger (15 men, 12 women). The three groups were compared in regard to symptoms, esophageal motility, and health-related QOL (HRQOL). All patients underwent esophageal manometry examination and completed a self-administered questionnaire concerning their symptoms; HRQOL assessment was based on results of the Short Form-8 General Health Survey. Symptoms rated ≥4 points on the Likert scale were defined as significant. Although all patients had dysphagia as a major symptom, more elderly patients reported globus sensation, whereas more young patients reported heartburn as the primary symptom. Manometric diagnoses were generally similar across the three groups. Ineffective esophageal motility was more prevalent in Groups A and C than in Group B, although the difference was not statistically significant. No significant differences in manometric parameters or HRQOL were detected among the three groups. Despite differences in symptom patterns, broad manometric diagnoses and impairment of HRQOL in elderly patients with dysphagia are similar to those in younger counterparts.

    We report here, results of investigation of changes in the condition of elderly patients, 80 years of age or older (EP-80), treated with radiation, and analysis of the results of radiotherapy to assess the value of radiotherapy in treating the elderly. Between 1970 and 1989, 294 EP-80 with various malignant tumors received radiation therapy at the Department of Radiology, Gunma University Hospital. The number of EP-80 treated has increased recently to about thirty per year, and their incidence among newly registered patients has also increased to over 5%. The 5-year cause specific survival rates for male and female were 14% and 32%, respectively. There was a significant difference between the survival rates for male and female (x 2 =11.89, p=0.00056) because of inclusion of a significant proportion of female patients with gynecological malignancies. The 5-year survival rate for patients in the curative radiotherapy group (CRG) was 30%, whereas no patient of the palliative radiotherapy group (PRG) has survived for 5 years (x 2 =90.23, p=0.00000). In the CRG, the survival rate for females was significantly higher than that for males (x 2 =11.48, p=0.00070). Thirty-one patients survived for 5 year. Head and neck cancer and uterine lervix cancer were the most common tumors in 5 year survivors. Age was not a significant prognostic factor in the elderly patients treated with radiation. It is considered that radiation therapy is as valuable in elderly patients as in the younger patient population. (author)

    Full Text Available We evaluate in this study the factors associated with the effect of age on blood pressure in more than 4800 patients. Their physicians referred them to evaluate for secondary causes for their hypertension. Factors studied included history and physical examination, serum sodium, potassium and creatinine, a stimulated plasma renin and catecholamine. We also studied the blood pressure response to infusion of either saralasin (an angiotensin II analogue or enalapril (an angiotensin converting enzyme inhibitor, and plasma aldosterone and cortisol after infusion of saline. We measured serum thyroxin and thyroid stimulating hormone concentrations on 1061 consecutive patients in this series. The results of our study show that increased age is associated with a significant increase in the prevalence of hypertension and especially of systolic hypertension after age 60 years. Increased obesity between age 30-50 years is associated with significant increases in diastolic blood pressure and this trend is also seen in African-Americans who are heavier than whites. Increased age is associated with an increased prevalence of secondary forms of hypertension including atherosclerotic renovascular hypertension, renal insufficiency and primary hypothyroidism.

    Full Text Available ABSTRACT Background International studies have demonstrated an increase in the prevalence of boys and a decrease of patients’ age at the beginning of outpatient treatment for eating disorders (ED. Objective To evaluate if these changes are also present in the Brazilian population participating in the PROTAD, a Brazilian ED program, and to discuss its clinical implication for treatment. Methods Cross-sectional study. We evaluated 150 medical records of patients under 18 years diagnosed with ED (DSM IV-TR. Patients were divided into two groups: G1 (2001-2007 (n = 77 and G2 (2008-2014 (n = 73. The girl/boy proportion and the mean age of patients were compared. Results In G1, six boys (7.8% were admitted (girl/boy proportion: 11.8:1, while in G2, 16 (22% boys were admitted (girl/boy proportion: 3.5:1 (p 0.05. Discussion The increase in the number of boys treated for EDs reported in international studies was also found at the PROTAD. Contrary to what has been reported in international studies, the mean age of patients at the PROTAD did not decrease significantly. Gender and sexual orientation issues, clinical presentation, prior overweight history and culture/media impact on boys should be addressed by the healthcare team to increase the therapeutic efficacy.

    Objective: To investigate the clinical features and evaluate the efficacy of manual reduction in treatment of age patients with secondary benign paroxysmal positional vertigo (s-BPPV). Methods: Thirty-two cases of aged patients ( the s-BPPV group: including 19 cases of female and 13 males, age from 60 to 86 years old)with secondary benign paroxysmal positional vertigo from Jul. 2013 to Sep. 2015 in our hospital were retrospectively analyzed. The results were compared with 121 patients( the primary group: including 82 cases of female and 39males, aged from 60 to 86 years old)with aged primary benign paroxysmal positional vertigo(p -BPPV). All the patients were followed up for 12 months. Statistical data analysis was carried out with SPSS 19.0. Results: 20.92%(32/153)of all the observed elderly patients with BPPV was the aged s-BPPV. The sex ratio and onset age had no significant difference between the two groups(χ(2)=0.79, P >0.05; t =0.37, P >0.05). The rate of two or more semicircular canal involvement in the secondary group(21.88%) was higher than that in primary group(6.61%)(χ(2)=6.67, P manual reduction was 57.50%(23/40)in secondary group and 82.31%(107/130)in primary group, the difference was significant(χ(2)=10.46, P manual reduction in secondary group and 91.54%(119/130) in primary group, the difference was not significant(χ(2)= 0.59, P >0.05). The numbers of circulation of the first successful manual reduction management were (3.9±1.3)times in secondary group and (2.1±1.1)times in primary group, the difference was significant( t =3.15, P manual reduction of secondary BPPV is lower than primary BPPV, it's needed more circulation of first success in manual reduction management. The total effective rates are not significant in two groups and recurrence rate is relatively high in secondary group.

    In long-term survivors of osteosarcoma and Ewing sarcoma treated with the addition of radio- and chemotherapy, low bone mineral density (BMD) and fractures have been observed, presumably resulting from these adjuvants. Because patients with chondrosarcoma usually are not treated with conventional adjuvant treatment, observation of low BMD in patients with chondrosarcoma presumably would be the result of other mechanisms. However, BMD in patients with a history of chondrosarcoma has not been well characterized. The aim of our study was to address the following questions: (1) Do long-term survivors of chondrosarcoma have normal BMD and, if not, which factors contribute to low BMD? (2) Is there a greater risk of fracture and does the Fracture Risk Assessment Tool (FRAX(®)) score reflect fracture likelihood? All known patients with a history of chondrosarcoma treated at our institution before 2006 were identified. Of 127 patients believed to be alive at the time of this study, 30 agreed to participate in this study (11 females, 19 males; mean age at surgery, 39 ± 12 years; mean followup, 12 ± 5 years). With the data available, the 30 participants were not different from the 97 nonparticipants in terms of age, sex, BMI, tumor grade, tumor location (axial versus appendicular, lower extremity versus elsewhere), and use of any treatment known to influence osteopenia (chemotherapy, lower extremity surgery). BMD was measured and history of fractures was assessed using a questionnaire. The patients´ BMD measurements in this study were sex- and age-matched with a normative sex- and age-categorized reference population reported by Kudlacek et al. Associations were tested by univariate regressions and ANOVAs of all measures of BMD and eligible oncologic and demographic factors. Eighteen of 30 (60%) patients had a pathologic BMD according to the WHO dual-energy x-ray absorptiometry definition, 15 (50%) had osteopenia, and three (10%) had osteoporosis. T-scores in the

    Full Text Available BACKGROUND Diabetes mellitus is common endocrine disorder which involves multiple organs and leads to significant morbidity and mortality due to accompanying complications. Erectile dysfunction, reduced libido, orgasmic dysfunction, and retrograde ejaculation are established complications found with variable prevalence in men with diabetes. METHODOLOGY In the present study, total 90 male patients of diabetes mellitus of age below 40 years were taken from medical outpatient department and indoor patients of medical wards of a tertiary care teaching hospital of South Delhi. They were evaluated for complains regarding sexual dysfunction. Hormonal assays of serum free testosterone, LH, FSH, C-peptide, HbA1c and lipid profile were carried out in all patients. RESULT Present study shows that testosterone deficiency is quite common in young diabetic patients. Low serum free testosterone was more common in type 2 diabetes as compared to type 1 diabetes (38.46% Vs 29.41%. BMI has significant effect on serum free testosterone levels. Patients with higher BMI had negative correlation to free testosterone although testosterone deficiency was also seen in few lean patients. High serum triglyceride and low serum HDL were seen more frequently in patients with low free testosterone. CONCLUSION This study reveals that hypogonadism is not a rarity even at initial stages of diabetes. This study, although small, highlights importance of assessment of young diabetic patients for sexual dysfunction and hypogonadism.

    Full Text Available Objective: To describe the current knowledge and management of aging and pharmacotherapeutic complexity in HIV + patients. Method: A review of literature was carried out, including articles, originals or reviews, published in English or Spanish, from 2007 to 2017, which analysed the aging and pharmacotherapeutic complexity in HIV + patients. The terms «Polypharmacy»/»Polypharmacy», «Aging»/»Aging», «Frailty»/»Fragility», «Pharmacotherapeutic Complexity»/»Medication Regimen Complexity» and «HIV»/”HIV» were combined. The review was carried out independently by two authors. The degree of agreement, according to the Kappa index, was analysed. Results: A total of 208 references were analysed, including, finally, only 68. An aging of the population and an increase in associated comorbidities have been identified, especially over 50 years-old. Immunological changes similar to those that are generated in a non-infected elderly population have been described. These conditions influencing the prescription of antiretroviral treatment, according to studies identified. In parallel, polypharmacy is increasingly present, being defined exclusively by the concomitant use of five drugs. Pharmacotherapeutic complexity, through the Medication Regimen Complexity Index, has begun to analyse and relate to health outcomes. There has been a need to know and apply concepts already known in non-HIV-aged population, such as de-prescription, potentially inappropriate medication, cholinergic risk, although few results are available. Conclusions: There is a growing interest to know about the relationship between HIV and aging. Pharmacotherapeutic complexity is beginning to be used as a pharmacotherapeutic follow-up criterion due to its influence on health outcomes. It is necessary to manage and incorporate new concepts that help pharmacotherapeutic optimization in this population

    Aging is now a well-recognized characteristic of the HIV-infected population and both AIDS and aging are characterized by a deficiency of the T-cell compartment. The objective of the present study was to evaluate the impact of antiretroviral (ARV) therapy in recovering functional response of T cells to both HIV-1-specific ENV peptides (ENV) and tetanus toxoid (TT), in young and aged AIDS patients who responded to ARV therapy by controlling virus replication and elevating CD4(+) T cell counts. Here, we observed that proliferative response of T-cells to either HIV-1-specific Env peptides or tetanus toxoid (TT) was significantly lower in older antiretroviral (ARV)-treated patients. With regard to cytokine profile, lower levels of IFN-γ, IL-17 and IL-21, associated with elevated IL-10 release, were produced by Env- or TT-stimulated T-cells from older patients. The IL-10 neutralization by anti-IL-10 mAb did not elevate IFN-γ and IL-21 release in older patients. Finally, even after a booster dose of TT, reduced anti-TT IgG titers were quantified in older AIDS patients and it was related to both lower IL-21 and IFN-γ production and reduced frequency of central memory T-cells. Our results reveal that ARV therapy, despite the adequate recovery of CD4(+) T cell counts and suppression of viremia, was less efficient in recovering adequate immune response in older AIDS patients.

    Falls in the elderly are a significant cause of morbidity and mortality. We sought to better categorize this patient population and describe factors contributing to their falls. This is a retrospective review of geriatric patients presenting to a level 1 community trauma center. We queried our trauma database for all patients 65 years and older presenting with fall and triaged to the trauma bay from 2008 to 2013. Researchers reviewed the patients' trauma intake paperwork to assess mechanism, injury, and location of fall, whereas discharge summaries were reviewed to determine disposition, morbidity, and mortality. A total of 650 encounters were analyzed. Five hundred thirty-nine resided at home (82.9%), 110 presented from nursing homes or assisted living (16.9%), and 1 came from hospice (0.15%). Ninety-five patients died or were placed on hospice as a result of their falls (14.7%), of which 88 came from home. Controlling for Injury Severity Score, living at home was an independent risk factor for fall-related mortality (odds ratio, 3.0). Comparing the elderly (age 65-79 years; n = 274) and the very elderly (age ≥80 years; n = 376), there were no differences in Injury Severity Score (P = .33), likelihood of death (P = .49), likelihood of C-spine injury (P = 1.0), or likelihood of other axial or long bone skeletal injury (P = .23-1.0). There was a trend for increased likelihood of head injury in very elderly patients (P = 0.06). Prevention measures to limit morbidity and mortality in elderly fall patients should be aimed at the home setting, where most severe injuries occur. Very elderly patients may be at increased risk for intracranial fall-related injuries. Copyright © 2015 Elsevier Inc. All rights reserved.

    Purpose: To evaluate prostate-specific antigen (PSA) spikes after permanent prostate brachytherapy in low-risk patients. Methods and Materials: The study population consisted of 164 prostate cancer patients who were part of a prospective randomized trial comparing 103 Pd and 125 I for low-risk disease. Of the 164 patients, 61 (37.2%) received short-course androgen deprivation therapy. The median follow-up was 5.4 years. On average, 11.1 post-treatment PSA measurements were obtained per patient. Biochemical disease-free survival was defined as a PSA level of ≤0.40 ng/mL after nadir. A PSA spike was defined as an increase of ≥0.2 ng/mL, followed by a durable decline to prespike levels. Multiple parameters were evaluated as predictors for a PSA spike. Results: Of the 164 patients, 44 (26.9%) developed a PSA spike. Of the 46 hormone-naive 125 I patients and 57 hormone-naive 103 Pd patients, 21 (45.7%) and 8 (14.0%) developed a PSA spike. In the hormone-naive patients, the mean time between implantation and the spike was 22.6 months and 18.7 months for 125 I and 103 Pd, respectively. In patients receiving neoadjuvant androgen deprivation therapy, the incidence of spikes was comparable between isotopes ( 125 I 28.1% and 103 Pd 20.7%). The incidence of spikes was substantially different in patients 125 I and/or <65 years of age. Differences in isotope-related spikes are most pronounced in hormone-naive patients

    Full Text Available Patients aged above 60 represent a very diversified population group with respect to their health condition. This may result from multimorbidity. In the rehabilitation process of elderly patients it is especially crucial to identify not only the underlying diseases which constituted the grounds for referral to the rehabilitation clinic, but also the comorbidities that have to be taken into consideration while planning their rehabilitation. The aim of the present paper is the assessment of comorbidities in patients of the rehabilitation clinic. The study population included 1616 patients (447 man and 1169 women treated at the rehabilitation clinic. The factors put through analysis were the age and gender of the patient, the main diagnosed (underlying illness subject to rehabilitation treatment, as well as comorbidities. All diseases, both the underlying conditions and the comorbidities have been classified according to the International Statistical Classification of Diseases and Related Health Problems (10th revised edition. The main reasons for the treatment at the rehabilitation outpatient clinic were arthrosis of the spine, knee and hip joints, polyarthritis, osteoporosis, diseases of the central nervous system diseases and paralytic syndromes as consequences of strokes, hypertension or atherosclerosis, as well as post-traumatic conditions.

    Immunotherapy has dramatically changed the therapeutic scenario in non-small cell lung cancer (NSCLC), extending overall survival, with a favorable safety profile. However, there is still a gap of knowledge about the efficacy of immune checkpoint inhibitors (ICIs) in elderly patients. Data from randomized clinical trials testing ICIs are conflicting and often lack adequate statistical power. Although two large meta-analyses suggested an absence of a significant survival benefit in patients older than 75years, expanded access programs and retrospective cohort studies of ICIs in the real-life setting, showed comparable survival outcomes and safety profiles between older and younger patients. In this complex scenario, a further unresolved issue is the potential correlation between older age and immunotherapy primary resistance, a phenomenon probably linked to the continuous and progressive remodeling of immune functions with ageing, known as immunosenescence. Defining the role of ICIs in elderly NSCLC patients and exploring the molecular mechanisms underlying a possible lack of benefit or even accelerated tumor growth during immunotherapy are two major challenges for future research in this field of cancer treatment. In this review, we describe the major hallmarks of immunosenescence and we summarize the existing clinical data of ICIs in elderly NSCLC patients. Copyright © 2017 The Author(s).

    Hyponatraemia is a serious adverse event commonly reported in elderly people treated with serotonergic antidepressants. The mechanism, incidence and risk factors for antidepressant induced hyponatraemia are not fully understood. In a retrospective chart analysis, depressed patients aged >63 years were investigated for change in serum sodium levels between two time points, separated by a median period of 45.5 days, with the first specimen taken prior to treatment. Patients were grouped into three cohorts; treated with an SSRI or SNRI (n=77), treated with an antidepressant other than an SSRI or SNRI (n=54) and not treated with an antidepressant (n=128). For change in sodium level between measurements and total number of patients with hyponatraemia, there was no significant difference between cohorts. However, the rate of reduction of serum sodium levels between time points was significantly greater for SSRI and SNRI treated patients (pmodelling showed that the risk of hyponatraemia increases with increased age, female gender, and particularly the antidepressant agents sertraline and escitalopram. The findings are of clinical significance as they demonstrate that hyponatraemia can occur rapidly with antidepressants, and SSRI/SNRI medications induce more rapid changes. They support the use of electrolyte monitoring early in antidepressant treatment in patients receiving antidepressants.

    This is the first report to illustrate the marsupialization as an effective treatment for a Down Syndrome (DS) patient presenting a residual periapical cyst. These cysts occur within the alveolar ridge, usually at the local site of a previously extracted tooth that did not received proper curettage; usually the surgical excision of a cyst and also the vigorous curettage of a socket is very simple, if not for the fact that mentally disabled patients require rapid and non-stressful procedures. The 54-year-old DS patient represented herein received a minimally invasive marsupialization under local anesthesia. Due to the large extent of the lesion, the acrylic resin drain was maintained for 30 days. Through the following period, a daily irrigation of the cystic cavity with saline solution was carried out to prevent a secondary infection within the cystic cavity. A follow-up of 16 months showed no signs of recurrence. Marsupialization of residual periapical cyst is completely effective and safe, even for a DS patient that is considered to be at an advanced age. Marsupialization poses as a minimally invasive choice for mentally disabled patients, even when presenting advanced ages; treatment success was stated by the easy clinical conduct, uneventful postoperative situation and the lack of recurrence along 16 months of follow-up.

    Aims This study aimed to compare the clinical outcomes of rotator cuff repair in patients with rheumatoid arthritis with those of patients who have no known history of the disease. We hypothesised that the functional outcomes are comparable between patients and without rheumatoid arthritis and may be affected by the level of disease activity, as assessed from C-reactive protein (CRP) level and history of systemic steroid intake. Patients and methods We conducted a retrospective review of the institutional surgical database from May 1995 to April 2012. Twenty-nine patients with rheumatoid arthritis who had rotator cuff repair were enrolled as the study group. Age, sex, and tear size matched patients with no disease who were selected as the control group. The mean duration of follow-up was 46 months (range 24-92 months). Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) questionnaire, Constant score and visual analogue scale (VAS). All data were recorded preoperatively and at regular postoperative follow-up visits. CRP was measured preoperatively as the disease activity marker for rheumatoid arthritis. Medication history was thoroughly reviewed in the study group. Results In patients with rheumatoid arthritis, all shoulder functional scores improved after surgery (ASES 56.1-78.1, Constant 50.8-70.5 and VAS 5.2-2.5; P rheumatoid arthritis was comparable to that of the control group (difference with control: ASES 78.1 vs. 85.5, P = 0.093; Constant 70.5 vs. 75.9, P = 0.366; VAS 2.5 vs. 1.8, P = 0.108). Patients with rheumatoid arthritis who had an elevated CRP level (> 1 mg/dl) showed inferior clinical outcomes than those with normal CRP levels. Patients with a history of systemic steroid intake showed inferior functional outcomes than those who had not taken steroids. Conclusions Surgical intervention for rotator cuff tear in patients with rheumatoid arthritis improved the shoulder functional outcome comparable to that in

    Previous studies of young people have revealed that the left dorsolateral prefrontal cortex (DLPFC) plays an important role in inductive reasoning. An fMRI experiment was performed in this study to examine whether the left DLPFC was involved in inductive reasoning of MCI patients and normal aging, and whether the activation pattern of this region was different between MCI patients and normal aging. The fMRI results indicated that MCI patients had no difference from normal aging in behavior performance (reaction time and accuracy) and the activation pattern of DLPFC. However, the BOLD response of the DLPFC region for MCI patients was weaker than that for normal aging, and the functional connectivity between the bilateral DLPFC regions for MCI patients was significantly higher than for normal aging. Taken together, these results indicated that DLPFC plays an important role in inductive reasoning of aging, and the functional abnormity of DLPFC may be an earlier marker of MCI before structural alterations.

    The prognostic value of gender and age in the survival of nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiotherapy (IMRT) is unclear. Several studies have suggested a female advantage in the prognosis of solid tumors. We investigated the relationship between gender differences and disease outcome in NPC patients treated with IMRT in South China. A total of 299 patients with non-disseminated NPC were analyzed retrospectively. IMRT was delivered with a simultaneous modulated, accelerated radiotherapy boost technique at prescribed doses of 70 Gy/30 fractions/6 weeks to the primary tumor (GTVp) and positive neck nodes (GTVn), 60Gy (2.0 Gy/day) to the clinical target volume (CTV) and upper neck region and 54 Gy (1.8 Gy/day) to the clinically negative low neck. A median boost dose of 9.2 Gy (4–20 Gy) was administered to patients with persistent disease at the primary site. With a median follow-up of 52 months, the male patients had a significantly unfavorable 5-year OS (70.7% compared to 94.1%, P < 0.001), DPFS (71.5% compared to 87.3%, P = 0.029) and DMFS (77.2% compared to 89.7%, P = 0.036) than the female patients. In patients younger than 45, the male patients had a poorer 5-year OS (66.8% compared to 91.2%, P = 0.008), DPFS (59.9% compared to 91.2%, P = 0.005) and DMFS (66.4% compared to 94.0%, P = 0.004) than the female patients. For patients older than 45, only the 5-year OS (72.2% compared to 96.0%, P = 0.001) was significantly different. Gender and age are strong independent prognostic factors for NPC in this study. We are the first to report that younger male patients were more likely to have distant metastases and exhibited inferior overall survival and disease progression-free survival rates compared to other patients

    Objective: To evaluate the changes of coagulation and fibrinolysis function in the middle-old aged patients with nonvalvular atrial fibrillation. Methods: The levels of D-Dimer and tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) were detected in 92 middle-aged patients with nonvalvular atrial fibrillation (AF group) and 60 patients with sinus rhythm (control group) by immune turbidimetry and enzyme linked immunoadsorbent assay (ELISA). Univariate analysis was used to determine the differences between two groups, and covariance analysis was used to determine the factors which might affect coagulation and fibrinolysis indexes. Results: 1)The plasma levels of D-Dimer [(0.16±0.10) mg·L -1 ] and t-PA [(42.58± 30.28) μg·L -1 ] and PAI-1 [(86.03 ± 21.43) μg·L -1 ] in AF group were significantly higher than those in the control group [(0.10 ± 0.08) mg·L -1 , (26.02±13.84) μg·L -1 , (64.94±24.35) μg·L -1 ] (P<0.05 or P <0.001). The ratio of PAI-1/t-PA in AF group was higher than that in control group slightly. 2) After adjustment of the factors which included sex, age and plasma creatinine, uric acid, blood sugar, triglyceride and cholesterol, the levels of D-Dimer (P=0.047), t-PA (P=0.264) and PAI-1 (P=0.001) in AF group were higher than those in the control group. Conclusion: The middle-old aged patients with nonvalvular atrial fibrillation lose their balance of coagulation and fibrinolysis in the state of hypercoagulated and hypofibrinolysis. (authors)
