Neuropsychological Sequelae of Patients Treated with Microsurgical Clipping or Endovascular Embolization for Anterior Communicating Artery Aneurysm

Background and Purpose: While microsurgical clipping has been the choice of treatment for anterior communicating artery (ACoA) aneurysm, endovascular embolization is increasingly popular for treating intracranial aneurysms. Previous studies showed that in terms of mortality (i.e., death) and morbidity (i.e., functional outcome, independent living, rebleeding) rates, the clinical outcomes of coil embolization for intracranial aneurysms are as good as or even better than those of surgical clipping. However, little is known about the impact of these treatments on the cognitive functions of those survived after the treatment. Thus, the present study is designed to examine the cognitive deficits of patients treated with either surgical clipping or coil embolization. Method: Eighteen patients with a ruptured ACoA aneurysm were recruited. Half of them had undergone surgical clipping and the other half had endovascular embolization. Standardized neuropsychological tests were employed to assess their memory, executive function, motor ability, language and visual perceptual abilities. Results: The performance of the patients was in general poorer than that of the normal control subjects on tests of verbal memory, flexible thinking, ability to resist interference and motor control. However, in terms of severity, the patients who received surgical clipping demonstrated more severe impairment than those had endovascular embolization on these cognitive domains. In addition, while 33% of patients in the clipping group showed impairments on memory and executive function, no patient in the embolization group demonstrated these impairments. Conclusions: Patients with ACoA aneurysm demonstrated impaired verbal memory, executive function and motor abilities while their language and visual perception abilities remained relatively intact. However, when comparing the effect of treatment choice on the cognitive functions of these patients, the present results favored the coil embolization as the patients treated with coil embolization demonstrated significantly fewer severe cognitive deficits than patients who had undergone surgical clipping.
Methacholine Bronchial Hyperresponsiveness inChronic Sinusitis

The coexistence of chronic sinusitis (CS) may deteriorate the clinical condition of lower airway diseases such as bronchial asthma (BA) or chronic bronchitis (CB). However, the bronchial hyperresponsiveness (BH) in CS without any apparent lower airway disease is not fully understood nor are the effects of treatment. We examined lower airway hyperresponsiveness to methacholine (MCh) in 42 subjects with CS but without allergic rhinitis (AR) who had normal lung functions without any pulmonary symptoms, comparing it with that of 50 subjects with stable BA, 50 subjects with simple CB and 40 subjects with AR, and further examined the effect of endoscopic sinus surgery in 7 CS subjects with BH. The BH to MCh was measured in terms of the minimum dose (Dmin), defined as the cumulative dose at the point where respiratory conductance began to decrease. A Dmin <50 units was defined as BH. Seventy-one percent of CS subjects showed BH without relation to the severity or duration of CS, or atopic status. BH in CS subjects, which was less than that in BA subjects, was similar to that in simple CB or AR in both its prevalence and degree. After the surgical treatment of CS, BH significantly decreased (p < 0.01) with improvements in both nasal symptoms and sinus lesions. These findings suggest that CS itself induces BH to a degree similar to simple CB and AR without any relationship to the clinical background, and that adequate treatment of CS reduces BH.
Effect of Conjugated Linoleic Acid on Leptin Level: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Abstract The results of human clinical trials examining the effects of conjugated linoleic acid (CLA) on leptin concentration are inconsistent. Our objective was to elucidate the role of conjugated linoleic acid supplementation on leptin through a systematic review and a meta-analysis of available randomized placebo-controlled trials (RCTs). We searched the PubMed, SCOPUS, and ISI web of science up to February2017, in English, to identify RCTs investigating the effect of CLA supplements on plasma leptin concentrations. Weighted mean differences (WMDs) and their respective 95% confidence intervals (CIs) were calculated to assess the efficacy of CLA on leptin concentration by using random effects. Statistical heterogeneity, study quality, meta-regression and publication bias were used based on standard methods. Nineteen RCTs (comprising 26 treatment arms) with 1045 subjects were included in this meta-analysis. Random-effect meta-analysis found a slight but not significant reduction in plasma leptin concentrations (WMD: –0.38 ng/ml, 95% CI: –1.08, 0.32, p=0.286); I2=53.24%, p=0.001), following CLA supplementation. The pooled effect size was robust and remained non-significant in the leave-one-out sensitivity analysis. Subgroup analysis based on BMI status showed that the CLA supplementation significantly reduces leptin when used for obese subjects (WMD: –1.47 ng/ml, 95% CI: –2.15, –0.79, p<0.001) and in the subset of trials lasting<24 weeks of duration (WMD: –0.76 ng/ml, 95% CI: –1.40, –0.12, p=0.019). CLA supplementation might moderately decrease circulatory leptin levels only among obese adults for shorter than 24 weeks. Additional high-quality studies are needed to replicate our results.
Herbicidal activity of slow-release herbicide formulations in wheat stands infested by weeds

ABSTRACT The present study reports the herbicidal activity of metribuzin and tribenuron-methyl embedded in the degradable matrix of natural poly-3-hydroxybutyrate [P(3HB)/MET and P(3HB)/TBM]. The developed formulations were constructed as films and microgranules, which were tested against the weeds such as white sweet clover Melilotus albus and lamb's quarters Chenopodium album in the presence of soft spring wheat (Triticum aestivum, cv. Altaiskaya 70) as the subject crop for investigation. The activity was measured in laboratory scale experiments by determining the density and weight of the vegetative organs of weeds. The study was also aimed at testing the effect of the experimental formulation on the growth of wheat crop as dependent on the method of herbicide delivery. The experimental MET and TBM formulations showed pronounced herbicidal activity against the weed species used in the study. The effectiveness of the experimental formulations in inhibiting weed growth was comparable to and, sometimes, higher than that of the commercial formulations (positive control). The amount of the biomass of the wheat treated with the experimental herbicide formulations was significantly greater than that of the wheat treated with commercial formulations.
The interactive role of eating regulation and stress in the prediction of weight‐related outcomes among college students

The interactive role of eating regulation and perceived stress on weight-related outcomes was examined among 319 sophomore year college students (110 males and 209 females). Moderated regressions were used to examine interactions between stress and eating regulation on study outcomes including body mass index (BMI) and body fat. Eating regulation moderated associations between stress and BMI and body fat outcomes. Students reporting high perceived stress, high autonomous eating regulation, low controlled regulation, and low amotivation exhibited higher outcomes (BMI and body fat) than those with similar eating regulation but lower perceived stress. Students with lower autonomous eating regulation and higher controlled regulation had no differences in study outcomes across levels of stress. College students who regulate their eating behaviours for health reasons (specifically showing autonomous regulation) exhibit higher BMI and body fat when they report higher levels of perceived stress. Health promotion programs for college students need to target education efforts towards stress reduction and healthy eating behaviours.
Strokes in the Elderly – Higher Acute and 3-Month Mortality – An Explanation

Aim: Stroke is common in older people. The objective of the study was to determine if older stroke patients have a higher mortality and disability compared with younger patients for comparable stroke severity and pathology and whether there is an explanation for the difference. Methods: A prospective study was undertaken in 296 consecutive patients admitted with acute stroke. Patients were studied for neurological features, pre-stroke functional disability, severity of stroke defined by stroke syndromes and pathology of stroke on CT scans (202 patients). Post-stroke disability was defined according to the functional status within 72 h of admission. A record was made of the intercurrent illness while the patients were in acute wards and of the risk factors. Patients were dichotomised into two age groups: younger group – up to 75 years (163 patients) and older group – over 75 years (133 patients). Outcome was measured according to (1) discharge status from acute wards, i.e., dead or alive, and (2) mortality at 3 months. Results: Although there was no significant difference in severe clinical stroke syndromes (p = 0.72), CT scan features (p = 0.68) and pyrexia (0.38) between the two age groups, the older patients had significantly more disabling strokes as defined on Barthel Index (p = 0.015) and a higher mortality in the acute phase (p < 0.01) and at 3 months (p = 0.001). The older stroke patients had more severe pre-stroke disability (p < 0.001) and more severe neurological impairment for similar stroke severity and pathology. Early mortality was more influenced by pre-stroke global health than age whereas 3-month mortality was influenced by age to the exclusion of all other known prognostic factors. Conclusion: The older stroke patients have more disabling stroke and an increased mortality for a similar spectrum of stroke severity and pathology. The explanation for higher mortality of the older patients is the poor pre-stroke health and higher immediate post-stroke disability.
The Association of Corporate Work Environment Factors, Health Risks, and Medical Conditions with Presenteeism among Australian Employees

Purpose. To investigate the impact of selected corporate environment factors, health risks, and medical conditions on job performance using a self-reported measure of presenteeism. Design. A cross-sectional survey utilizing health risk appraisal (HRA) data merging presenteeism with corporate environment factors, health risks, and medical conditions. Setting. Approximately 8000 employees across ten diverse Australian corporations. Subjects. Employees (N = 1523; participation rate, 19%) who completed an HRA questionnaire. Measures. Self-reported HRA data were used to test associations of defined adverse corporate environment factors with presenteeism. Stepwise multivariate logistic regression modeling assessed the relative associations of corporate environment factors, health risks, and medical conditions with increased odds of any presenteeism. Results. Increased presenteeism was significantly associated with poor working conditions, ineffective management/leadership, and work/life imbalance (adjusting for age, gender, health risks, and medical conditions). In multivariate logistic regression models, work/life imbalance, poor working conditions, life dissatisfaction, high stress, back pain, allergies, and younger age were significantly associated with presenteeism. Conclusions. Although the study has some limitations, including a possible response bias caused by the relatively low participation rate across the corporations, the study does demonstrate significant associations between corporate environment factors, health risks, and medical conditions and self-reported presenteeism. The study provides initial evidence that health management programming may benefit on-the-job productivity outcomes if expanded to include interventions targeting work environments.
Sexual dimorphism in the postcranial skeleton of New World primates.

This study examines sexual dimorphism in 24 dimensions of the postcranial skeleton of four platyrrhine species: Callithrix jacchus, Saguinus nigricollis, Saimiri sciureus, and Cebus albifrons. The two callitrichid species show a relatively small amount of variation in the degree of sexual dimorphism among the different dimensions. Variation is considerably higher in the two cebid species as reflected by a mosaic pattern of sexual dimorphisms with males being significantly larger than females in some dimensions, and females significantly larger than males in others. In dimensions of the pectoral girdle and limb bones, males and females in each of the two cebid species are essentially scaled versions of each other, with males being peramorphic compared to females. This pattern is primarily the result of time hypermorphosis, i.e. an extension of the growth period in time in males. Rate hypermorphosis, i.e. an increase in the rate of growth in time in males, appears to play an additional role, however, in S. sciureus. By contrast, in dimensions of the true pelvis, sex differences in shape are dissociated from those in size. They are interpreted as the result of acceleration, i.e. increase in rate of shape change in females, as an adaptation to obstetrical functions. Interspecific analyses indicate positive allometry of mean degree of postcranial dimorphism with respect to body size. This coincides with previous findings by Leutenegger and Cheverud [1982, 1985] on the scaling of sexual dimorphism in body weight and canine size, and thus supports their model which posits selection on body size as the prime mover for the evolution of sexual dimorphism.
Identifying Primary Care Pathways from Quality of Care to Outcomes and Satisfaction Using Structural Equation Modeling

OBJECTIVE To study the relationships between the different domains of quality of primary health care for the evaluation of health system performance and for informing policy decision making. DATA SOURCES A total of 137 quality indicators collected from 7,607 English practices between 2011 and 2012. STUDY DESIGN Cross-sectional study at the practice level. Indicators were allocated to subdomains of processes of care ("quality assurance," "education and training," "medicine management," "access," "clinical management," and "patient-centered care"), health outcomes ("intermediate outcomes" and "patient-reported health status"), and patient satisfaction. The relationships between the subdomains were hypothesized in a conceptual model and subsequently tested using structural equation modeling. PRINCIPAL FINDINGS The model supported two independent paths. In the first path, "access" was associated with "patient-centered care" (β = 0.63), which in turn was strongly associated with "patient satisfaction" (β = 0.88). In the second path, "education and training" was associated with "clinical management" (β = 0.32), which in turn was associated with "intermediate outcomes" (β = 0.69). "Patient-reported health status" was weakly associated with "patient-centered care" (β = -0.05) and "patient satisfaction" (β = 0.09), and not associated with "clinical management" or "intermediate outcomes. " CONCLUSIONS This is the first empirical model to simultaneously provide evidence on the independence of intermediate health care outcomes, patient satisfaction, and health status. The explanatory paths via technical quality clinical management and patient centeredness offer specific opportunities for the development of quality improvement initiatives.
Association between Vitamin D level and/or deficiency, and systemic lupus erythematosus: a meta-analysis.

This study aimed to evaluate the relationship between the level of 25-hydroxyvitamin D [25(OH)D] and systemic lupus erythematosus (SLE). We searched the PUBMED, EMBASE, and Cochrane databases and performed a meta-analysis examining the vitamin D level and/or deficiency in patients with SLE, compared with that in healthy controls. In total, 18 studies consisting of 1,083 patients with SLE and 1,273 controls were included. Vitamin D level was significantly lower in the SLE group than in the control group (standardized mean difference [SMD] = -0.938, 95% CI = -1.352 to -0.524, p = 9.0 × 10-6). Stratification by ethnicity showed a significantly decreased vitamin D level in the SLE group in the European and Arab populations (SMD = -1.485, 95% CI = -2.427 to -0.543, p = 0.002; SMD = -1.067, 95% CI = -1.251 to -0.883, p < 1.0 × 10-8), and an association tendency between decreased vitamin D level and SLE in the Asian population (SMD = -0.874, 95% CI = -2.073 to -0.324, p = 0.153). Subgroup analysis by sample size showed a significantly lower vitamin D level in the SLE group in small- (n ≤ 100) and large-sample (n > 100) populations (SMD = -1.008, 95% CI = -1.672 to -0.344, p = 0.003; SMD = -0.863, 95% CI = -1.444 to -0.293, p = 0.003). Meta-analysis revealed a significant association between SLE and vitamin D deficiency (RR = 2.321, 95% CI = 1.361-3.960, p = 0.002). Stratification by ethnicity showed a significant association between SLE and vitamin D deficiency in European and Arab populations (RR = 2.182, 95% CI = 1.024-4.648, p = 0.043; RR = 4.550, 95% CI = 3.471-5.965, p < 1.0 × 10-8). Our meta-analysis demonstrates that compared with controls, patients with SLE show significantly low serum levels of vitamin D, and that a deficiency of vitamin D is associated with SLE.
Anti-biofilm potential of phenolic acids: the influence of environmental pH and intrinsic physico-chemical properties

Abstract Phenolic acids are a particular group of small phenolic compounds which have exhibited some anti-biofilm activity, although the link between their activity and their intrinsic pH is not clear. Therefore, the present work examined the anti-biofilm activity (inhibition of biomass and metabolic activity) of phenolic acids in relation to the environmental pH, as well as other physico-chemical properties. The results indicate that, while Escherichia coli was not inhibited by the phenolic acids, both methicillin resistant Staphylococcus aureus and methicillin resistant Staphylococcus epidermidis were susceptible to the action of all phenolic acids, with the pH playing a relevant role in the activity: a neutral pH favored MRSE inhibition, while acidic conditions favored MRSA inhibition. Some links between molecular polarity and size were associated only with their potential as metabolic inhibitors, with the overall interactions hinting at a membrane-based mechanism for MRSA and a cytoplasmic effect for MRSE.
New Evidence on the Forward Premium Puzzle

Abstract The forward premium anomaly (exchange rate changes are negatively related to interest rate differentials) is one of the most robust puzzles in financial economics. We recast the underlying parity relation in terms of lagged forward interest rate differentials, documenting a reversal of the anomalous sign on the coefficient in the traditional specification. We show that this novel evidence is consistent with recent empirical models of exchange rates that imply exchange rate changes depend on two key variables: the interest rate differential and the magnitude of the deviation of the current exchange rate from that implied by purchasing power parity.
Effects of FSTL1 on cell proliferation in breast cancer cell line MDA-MB-231 and its brain metastatic variant MDA-MB-231-BR

In the past decades, altered Follistatin-like 1 (FSTL1) expression has been documented in a variety of cancers, while its functional roles are poorly understood. Particularly in breast cancer, the expression of FSTL1 and its signaling pathway remain to be determined. In the present study, an elevated FSTL1 expression and a supressed cell proliferation were detected in a specific brain metastatic cell line MDA-MB-231-BR (231-BR), compared with its parental cell line MDA-MB-231. However, this protein was hardly detected in the other three breast cancer cell lines. Next, lentiviral vectors encoding FSTL1 or FSTL1 specific shRNAs were used to overexpress or knock down FSTL1 in MDA-MB-231 or 231-BR, respectively (MDA-MB-231FSTL1 or 231-BRsh FSTL1). Results showed that overexpression of FSTL1 inhibited MDA-MB-231 cell proliferation, while knockdown of FSTL1 in 231-BR cells promotes cell proliferation, compared with their corresponding control groups. These results were further confirmed in nude mouse xenografts. The tumor volume in 231-BR cell-bearing mice was significantly smaller than that of MDA-MB-231 group, and reduction of tumor volume was detected in MDA-MB-231FSTL1 cell-bearing mice compared with the control group. Previous studies revealed that TGF-β-Smad2/3 signaling pathway was activated in 231-BR and MDA-MB-231FSTL1 cells, which may contribute to the inhibited cell proliferation. In addition, Smad3 knockdown could restore the inhibition of cell proliferation induced by FSTL1 overexpression in MDA-MB-231FSTL1 cells, indicating that the anti-proliferative effect of FSTL1 overexpression may be associated with Smad3 involved TGF-β signaling pathway regulation. This study identified FSTL1 as an inhibitor of cell proliferation in MDA-MB-231 and 231-BR cell lines, which may provide new insights into the development and management of breast cancer.
Developmental differences in approaches to nonsymbolic comparison tasks

Nonsymbolic comparison tasks are widely used to measure children’s and adults’ approximate number system (ANS) acuity. Recent evidence has demonstrated that task performance can be influenced by changes to the visual characteristics of the stimuli, leading some researchers to suggest it is unlikely that an ANS exists that can extract number information independently of the visual characteristics of the arrays. Here, we analysed 124 children’s and 120 adults’ dot comparison accuracy scores from three separate studies to investigate individual and developmental differences in how numerical and visual information contribute to nonsymbolic numerosity judgements. We found that, in contrast to adults, the majority of children did not use numerical information over and above visual cue information to compare quantities. This finding was consistent across different studies. The results have implications for research on the relationship between dot comparison performance and formal mathematics achievement. Specifically, if most children’s performance on dot comparison tasks can be accounted for without the involvement of numerical information, it seems unlikely that observed correlations with mathematics achievement stem from ANS acuity alone.
