Screening for Alzheimer's dementia at age 78 with short psychometric instruments

ABSTRACT Background: To date, no single instrument has proved to be adequate for screening for Alzheimer's dementia (AD). The aim of this study was to identify a combination of instruments which were highly sensitive for screening late onset AD. Methods: Subjects were drawn from the Vienna TransDanube Aging (VITA) study. This is an interdisciplinary, longitudinal community-based cohort study of the 21st and 22nd district of Vienna (Austria). Data refer to the cohort of 478 individuals at age 78 who took part in the first follow-up investigation of the VITA study. The psychometric instruments which were investigated were: the Ten-Point Clock Test, the Human-Figure Drawing Test, a Delayed Selective Reminding Test, Naming, the Trail Making Test-B, and Verbal Fluency. Further instruments were the Pocket Smell Test, and Subjective Memory Complaints. Data were analyzed using logistic regression analyses and cross validation. Results: A combination of the Delayed Selective Reminding Test and Verbal Fluency was best for screening AD (R2 = 0.38, main model). An area under the ROC curve of 0.829 was reached. This model discriminated between subjects with incident AD and subjects who did not have incident AD with a sensitivity of 91% and a specificity of 56%. Conclusion: The combination of an episodic memory test and a test of verbal fluency was an effective way of screening for AD.
Direct atomic structure determination by the inspection of structural phase

A century has passed since Bragg solved the first atomic structure using diffraction. As with this first structure, all atomic structures to date have been deduced from the measurement of many diffracted intensities using iterative and statistical methods. We show that centrosymmetric atomic structures can be determined without the need to measure or even record a diffracted intensity. Instead, atomic structures can be determined directly and quickly from the observation of crystallographic phases in electron diffraction patterns. Furthermore, only a few phases are required to achieve high resolution. This represents a paradigm shift in structure determination methods, which we demonstrate with the moderately complex α-Al2O3. We show that the observation of just nine phases enables the location of all atoms with a resolution of better than 0.1 Å. This level of certainty previously required the measurement of thousands of diffracted intensities.
GENOMIC INSTABILITY AND LIPID PEROXIDATION IN PATIENTS WITH TREATED ESSENTIAL HYPERTENSION

Impaired oxidant/antioxidant status in hypertension results in increased oxidative stress. This may cause genomic instability, damage membrane proteins and lipid peroxidation in hypertensive individuals. Aim: The aim of this study was to assess genomic instability (DNA damage) and lipid peroxidation in treated hypertensive patients belonging to a population sub-group. Materials and Methods: A case-control study was carried out on amlodipine-atenolol treated hypertensive patients (n=22) and normotensive (n=10) control group, belonging to same sub-group. The study was approved by Institutional Ethics Committee. The demographic, physiometric, anthropometric variables were recoded after the written informed consent. The leukocyte DNA damage by the single cell gel electrophoresis assay and malondialdehyde (MDA) levels using standard protocols were assessed in the study group to investigate genetic damage and oxidative stress. The data was expressed as mean ± S.E. M. Chi-square, student’s t-test, ANOVA, Pearson correlation and multiple linear regression were used to compare and find association if any of the damage parameter with the confounding variables. Results: DNA damage was significantly elevated (p=0.003) in the hypertensive patients compared to value in normotensive individuals. MDA levels were also significantly increased in patients. Conclusion: The increased genetic damage and levels of lipid peroxidation in hypertensive patients were associated with the elevated blood pressure, abnormal lipid profile, obesity and drug treatment. The genomic instability probably resulted as a consequence of oxidative stress from these variables and drug treatment increase the risk for cardiovascular diseases, target-organ damage and carcinogenesis.
CT-guided fine-needle aspiration cytology of solitary pulmonary nodules: a prospective, randomized study of immediate cytologic evaluation.

STUDY OBJECTIVE To evaluate the immediate cytologic assessment during CT-guided fine-needle aspiration cytology (FNAC) in the diagnosis of operable indeterminate solitary pulmonary nodules (SPNs). DESIGN Prospective randomized study. PATIENTS AND METHODS Two hundred twenty patients with SPN undergoing CT-guided FNAC were divided into two groups. In the first one (group A, 110 patients), a cytologist assessed the adequacy of the sample obtained immediately, and when the sample was considered inadequate, fine-needle aspiration (FNA) was repeated. In the second group (B, 110 patients), an immediate cytologic examination was not performed, but only a gross assessment by the surgeon. Histologic study of the SPN was possible in 217 cases, whereas three patients were followed up radiologically. RESULTS Adequate samples were obtained in 100% of group A and 88% of group B (p<0.001). The diagnostic accuracy was 99% in group A and 81% in group B (p<0.001). Group A required a mean of 1.22 FNAs compared with 1.10 in group B (p=0.015). The rate of pneumothorax in the whole series was 24%, and statistically significant differences between the two groups were not detected. CONCLUSIONS Immediate cytologic study significantly increased the adequacy and diagnostic accuracy of CT-guided FNAC of indeterminate SPNs without causing a significant increase of complications.
Safety and efficacy of once-daily fexofenadine HCl in the treatment of autumn seasonal allergic rhinitis.

Fexofenadine HCl (Allegra, Telfast) is approved in the US for twice-daily dosing in the treatment of seasonal allergic rhinitis (SAR). A once-daily dose (already available in some countries outside the US) can improve patient compliance and health outcomes. This multicenter, placebo-controlled, 14-day US study was conducted to compare the safety and effectiveness of once-daily fexofenadine HCl with placebo in the treatment of patients with moderate to severe autumnal SAR symptoms. After a 1-week placebo lead-in, patients received 120 or 180 mg fexofenadine HCl or placebo at 8 A.M. Patients recorded SAR symptom severity scores instantaneously (for the 1 hour before medication; i.e., trough blood levels), and reflectively (for the previous 12 hours) at 8 A.M. and 8 P.M. The primary efficacy measure was change from baseline in average instantaneous 8 A.M. total symptom score (TSS, the sum of individual symptom scores excluding nasal congestion). In 861 intent-to-treat patients, both fexofenadine HCl doses provided significant (p < or = 0.05) improvement in 8 A.M. instantaneous TSS compared with placebo. Similarly, both fexofenadine doses were superior to placebo for reflective TSS assessments (p < or = 0.0012). There were no statistical differences in efficacy between the two fexofenadine doses, though the 180 mg dose showed a trend toward greater symptom relief. Incidence of adverse events was similar between fexofenadine and placebo groups (30.2% and 30.0%, respectively), with headache the most frequently reported adverse event (8.9% and 7.5%, respectively). In conclusion, once-daily fexofenadine HCl, 120 or 180 mg, is safe and effective in the treatment of autumnal SAR.
Spectrum of esophageal dysmotility in systemic sclerosis on high-resolution esophageal manometry as defined by Chicago classification.

The classic manometric findings in systemic sclerosis are aperistalsis of the esophageal body with hypotensive lower esophageal sphincter. These changes contribute to gastroesophageal reflux disease in these patients. With widespread use of high-resolution esophageal manometry, diverse abnormalities are seen. The aim of this study is to characterize esophageal dysmotility in patients with systemic sclerosis undergoing high-resolution esophageal manometry and compare demographic features and diagnostic test results among patients with varying degrees of esophageal dysmotility. Patients with systemic sclerosis who underwent high-resolution esophageal manometry between January 2008 and October 2014 at our institution were identified. High-resolution esophageal manometry studies were reinterpreted using the Chicago Classification, v3.0 criteria. We also reviewed the patient charts for demographic data, indications for manometry, esophagogastroduodenoscopy findings, pH studies, medication use, and autoantibody panel. The cohort consisted of 122 patients with a mean age of 53.3 ± 15.3 years. High-resolution esophageal manometry was normal in 23, showed ineffective esophageal motility in 22, absent contractility in 73, and one case each of type II achalasia, esophagogastric junction outflow obstruction, hypercontractile esophagus, and distal esophageal spasm. Patients with absent contractility were younger and more likely to have erosive esophagitis, hiatal hernia, and esophageal strictures than patients with ineffective esophageal motility or normal manometry. There were no statistically significant differences in the groups based on autoantibodies or indications for manometry. Diverse esophageal motility abnormalities were noted in systemic sclerosis with ineffective esophageal motility or absent contractility observed in over three-fourth of the patients. Patients with absent contractility were younger and had more severe reflux. The severity of gastroesophageal reflux disease related endoscopic findings correlated with the degree of esophageal dysmotility on high-resolution esophageal manometry.
Breast-feeding and the Nutritional Status of Nursing Children in Chile 1

The work reported here sought to describe the feeding patterns of Chilean children up to 18 months old and their relation to nutritional status. To this end, a survey was conducted in 1993 of 9 330 Chilean children under 18 months old who were receiving care through the National Health Service System-which provides care for 75% of all children under age 6. The children, whose mothers or caretakers were interviewed, constituted 94% of a sample selected at randomfiom 102 of the 320 urban health clinics located throughout the county. The interview served to identib the type offeeding (exclusive breast-feeding, breast-feeding plus bottle-feeding, breast-feeding plus solid food, exclusive bottlelfeeding, or bottle-feeding plus solidfood) and to determine the nutritional status of the participants in terms of standards used by the United States National Centerfor Health Statistics and the World Health Organization. Children were deemed at risk of malnutrition if they had z scores on the weight-for-age distribution between 1.0 and 2.0 standard deviations below the US/WHO standard and as actually malnourished if they had z scores of over 2.0 standard deviations below the standard. The surveyfound exclusive breast-feeding prevalences of 86.5%, 66.7%, and 25.3% among infants 1,3, and 6 months old. Some 12.1% of the participants werefound to have a weight-forage deficiency, 30.770 exhibited a height-for-age deficiency, and 35.7% were found to be overweight. The prevalence of weight-for-age and height-for-age deficiencies were found to be considerably higher among bottle-fed children than among breast-fed children. In general, the results demonstrated the benefits of exclusive breast-feeding through thefirst 6 months of life, the need to complement exclusive breast-feeding with solid food after that time, and the superior nutritional status of breast-fed children within the age groups studied.
[The prevalence of skin and mucosal symptoms in gardeners handling Ficus benjamina (weeping fig) and Hedera helix (ivy). A cross-sectional study].

INTRODUCTION Allergic and toxic initiative symptoms from skin, eyes and respiratory tract are well known among gardeners This study reports the prevalence of these symptoms among gardeners working with Ficus Benjamina (Fb) and Hedera helix (Hh). MATERIAL AND METHODS A questionnaire concerning allergic/toxic-irritative symptoms from skin, eyes and respiratory tract were forwarded to 57 gardeners. A total of 49 questionnaires were returned and matched on sex and age with a control group. A number of 46 women and 52 men participated, with a mean age of 39 (SD 9.7). Differences in frequencies of symptoms were expressed as odds ratio (OR) with a security level of 95% after conditioned logistic regression; other results were calculated from Mantel-Haenzel test. RESULTS There were more complaints among gardeners compared to the control group f as to symptoms of asthmatic bronchitis (OR 4.6 [0.98-21.2]), rhino conjunctivitis (OR 6.4 [2.1-20.2]) and skin symptoms (OR 4.3 [1.5-12.5]). The symptoms were especially profound among the caretakers of Fb and Hh and to a lesser degree among gardeners working in greenhouses growing Fb and Hh. The symptoms of the gardeners were to a higher degree independent of the season (OR 3.1 [1.1-9]), related to working environment (OR 16.1 [3.3-78.9]) and indoor work (OR 24 [4.8-118.7]). DISCUSSION This study seems to demonstrate high frequencies of apparently allergic and/or toxic irritative symptoms among gardeners and should be followed by a study including clinical examinations. With knowledge of the allergenic and toxic irritative properties of Fb and Hh it seems problematic that these plants are found in such high numbers in public and private places. Allergic testing including these plants should be performed to a higher degree than is actually the case.

In-vitro biopotency and glycoform distribution of recombinant human follicle stimulating hormone (Org 32489), Metrodin and Metrodin-HP.

In this study the in-vitro biopotency and glycoform distribution of human recombinant follicle stimulating hormone (FSH, Org 32489) has been assessed. The biopotency of recombinant FSH was studied using animal (rat Sertoli) and human (granulosa-lutein) cell models. Recombinant FSH, as measured in the rat Sertoli cell assay, was more potent than the urinary preparations Metrodin, Metrodin-HP and IS 70/45 with half maximal stimulation (ED50; mean +/- SEM, n > 3) occurring at 2.2 +/- 0.5 IU/I (recombinant FSH), 4.7 +/- 1.1 IU/I (Metrodin), 13.2 +/- 0.7 IU/I (Metrodin-HP) and 6.4 +/- 0.3 IU/I (IS 70/45); the pituitary preparation IRP 83/575 had an ED50 of 10.4 +/- 0.1 IU/I. Using human granulosa-lutein cells, cultured for up to 4 days in the absence of exogenous steroid precursors, recombinant FSH was either without effect (three out of five patients) or inhibited both oestradiol and progesterone secretion. FSH (83/575) was without effect on oestradiol with preparations from any of the patients but slightly stimulated (134 +/- 8%; mean +/- SEM, P < 0.05) progesterone production at the highest dose (80 IU/I). The distribution of FSH isoforms, assessed by polyclonal radioimmunoassay, following chromatofocusing over the ranges pH < 3.5 and pH 3.5-7.0 respectively was recombinant FSH, 12.4 and 87.6%; Metrodin, 19.8 and 80.2%; Metrodin-HP, 50.2 and 49.8%; IS 70/45, 15.0 and 85.0%; IS 83/575, 70.9 and 29.1%. All glycoforms were pI < 7.0 for the five preparations. (ABSTRACT TRUNCATED AT 250 WORDS)
Cysteine Oxidation Targets Peroxiredoxins 1 and 2 for Exosomal Release through a Novel Mechanism of Redox-Dependent Secretion

Nonclassical protein secretion is of major importance as a number of cytokines and inflammatory mediators are secreted via this route. Current evidence indicates that there are several mechanistically distinct methods of nonclassical secretion. We have shown recently that peroxiredoxin (Prdx) 1 and Prdx2 are released by various cells upon exposure to inflammatory stimuli such as lipopolysaccharide (LPS) or tumor necrosis factor alpha (TNF-α). The released Prdx then acts to induce production of inflammatory cytokines. However, Prdx1 and 2 do not have signal peptides and therefore must be secreted by alternative mechanisms, as has been postulated for the inflammatory mediators interleukin-1β (IL-1β) and high mobility group box-1 (HMGB1). We show here that circulating Prdx1 and 2 are present exclusively as disulfide-linked homodimers. Inflammatory stimuli also induce in vitro release of Prdx1 and 2 as disulfide-linked homodimers. Mutation of cysteines Cys51 or Cys172 (but not Cys70) in Prdx2, and Cys52 or Cys173 (but not Cys71 or Cys83) in Prdx1 prevented dimer formation and this was associated with inhibition of their TNF-α-induced release. Thus, the presence and oxidation of key cysteine residues in these proteins are a prerequisite for their secretion in response to TNF-α, and this release can be induced with an oxidant. By contrast, the secretion of the nuclear-associated danger signal HMGB1 is independent of cysteine oxidation, as shown by experiments with a cysteine-free HMGB1 mutant. Release of Prdx1 and 2 is not prevented by inhibitors of the classical secretory pathway, instead, both Prdx1 and 2 are released in exosomes from both human embryonic kidney (HEK) cells and monocytic cells. Serum Prdx1 and 2 also are associated with the exosomes. These results describe a novel pathway of protein secretion mediated by cysteine oxidation that underlines the importance of redox-dependent signaling mechanisms in inflammation.
Prevalence and characteristics of the metabolic syndrome in 2479 hypopituitary patients with adult-onset GH deficiency before GH replacement: a KIMS analysis.

OBJECTIVE An increased risk of cardiovascular morbidity and mortality in adult GH deficiency (GHD) may be related to hypopituitarism but also to the presence of the metabolic syndrome (MetS). Our objective was to investigate the characteristics and prevalence of MetS as well as its comorbidities in adult GHD. Design In KIMS (Pfizer International Metabolic Database) 2479 patients with severe adult-onset GHD, naïve to GH replacement, with complete information on all MetS components were found. MetS was defined according to the National Cholesterol Education Program's Adult Treatment Panel III (NCEP) and the International Diabetes Foundation (IDF). METHODS The prevalence of MetS was calculated and compared with previously published data from the normal population. Associations were assessed between background variables, baseline variables, comorbidities, and MetS. RESULTS MetS was present in 43.1% (NCEP) and in 49.1% (IDF) of patients, clearly higher than data from the normal population (20-30%). MetS prevalence was related to age, GHD duration, and body mass index (BMI), but not to GHD severity, extent of hypopituitarism, or etiology of pituitary disease. Adjusted for age, gender, and BMI, patients with MetS had a higher prevalence ratio for diabetes mellitus: 4.65 (95% confidence interval (CI): 3.29-6.58), for cardiovascular morbidity: 1.91 (95% CI: 1.33-2.75), and for cerebrovascular morbidity: 1.77 (95% CI: 1.09-2.87) than patients without MetS. CONCLUSIONS MetS is highly prevalent in GHD and is associated with a higher prevalence ratio for comorbidities. The presence of MetS in GHD may therefore contribute to the increased risk of cardiovascular morbidity and mortality found in these patients.
Effect of hypertriglyceridemia on endotoxin responsiveness in humans

Triglyceride-rich lipoproteins can inhibit endotoxin activity in vitro and in rodents. We sought to determine whether Intralipid, a triglyceride-rich fat emulsion which in contact with plasma functions similarly to endogenous lipoproteins, can alter the human response to endotoxin. Intralipid inhibited endotoxin-induced cytokine production in human whole blood in vitro in a dose-dependent manner, with maximal inhibition (up to 70%) being achieved at a concentration of 10 g/liter. In healthy men, a bolus intravenous injection of endotoxin (lot EC-5; 20 U/kg of body weight) was given midway through a 4-h infusion (125 ml/h) of either 5% glucose (n = 5) or 20% Intralipid (n = 5). The infusion of Intralipid led to an increase in triglyceride levels in serum from 95 +/- 16 to 818 +/- 135 mg/dl prior to endotoxin administration, i.e., levels that importantly reduced cytokine production in endotoxin-stimulated whole blood. However, in vivo hypertriglyceridemia did not influence inflammatory responses to endotoxin (fever, release of tumor necrosis factor and soluble tumor necrosis factor receptors, and leukocytosis) or even potentiated endotoxin responses (release of interleukins 6 and 8 and neutrophil degranulation). Hypertriglyceridemia does not inhibit the in vivo responses to endotoxin in humans.
Patients’ experiences of using a smartphone application to increase physical activity: the SMART MOVE qualitative study in primary care

Background Regular physical activity is known to help prevent and treat numerous non-communicable diseases. Smartphone applications (apps) have been shown to increase physical activity in primary care but little is known regarding the views of patients using such technology or how such technology may change behaviour. Aim To explore patients’ views and experiences of using smartphones to promote physical activity in primary care. Design and setting This qualitative study was embedded within the SMART MOVE randomised controlled trial, which used an app (Accupedo-Pro Pedometer) to promote physical activity in three primary care centres in the west of Ireland. Method Taped and transcribed semi-structured interviews with a purposeful sample of 12 participants formed the basis of the investigation. Framework analysis was used to analyse the data. Results Four themes emerged from the analysis: transforming relationships with exercise; persuasive technology tools; usability; and the cascade effect. The app appeared to facilitate a sequential and synergistic process of positive change, which occurred in the relationship between the participants and their exercise behaviour; the study has termed this the ‘Know-Check-Move’ effect. Usability challenges included increased battery consumption and adjusting to carrying the smartphone on their person. There was also evidence of a cascade effect involving the families and communities of participants. Conclusion Notwithstanding technological challenges, an app has the potential to positively transform, in a unique way, participants’ relationships with exercise. Such interventions can also have an associated cascade effect within their wider families and communities.
