Concentration Levels of PM2.S and PM 10 Paper Dust in a Book Production Facility
Concentration levels of PM2.5 and PM10 paper dust were measured in a book production facility using a quantitative single subject study. Dust concentration data was collected in three processes of a book manufacturing facility; paper recycling, the digital pressroom and the digital bindery. Data was collected using the DustTrak DRX 8533 Aerosol Monitor, focusing on particulate sizes of PM2.5 and PM10. The data was used to determine if paper dust in the book production industry reached concentration levels that could have negative respiratory health effects on surrounding employees and to determine which process within the studied facility had the highest concentrations of paper dust. The study revealed that the paper recycling warehouse had the highest concentrations of paper dust. It was also determined that the paper recycling warehouse could cause negative respiratory health effects on surrounding employees. Further research is needed to determine the extent of those effects and potential remediation
Highly enantioselective Rh-catalyzed hydrogenations with heterocombinations of pentafluorobenzyl- and methoxybenzyl-derived binaphthyl phosphites
The Rh-catalyzed hydrogenations of dimethyl itaconate and methyl acetamido acrylate using selected heterocombinations of pentafluorobenzyl- and methoxybenzyl-derived binaphthyl phosphites proved to be highly enantioselective (ee 93\u201399%). In these selected cases the Rh-heterocomplexes, which were formed in a statistical amount (ca. 50% by 31P NMR), turned out to be more active and selective than the two homocomplexes

Combinations of acidic and basic monodentate binaphtholic phosphites as supramolecular bidentate ligands for enantioselective Rh-catalyzed hydrogenations
The combination of two chiral BINOL-derived monodentate phosphites, containing either a carboxylic acid (-COOH) or a tertiary amine (-NMe2), can be seen as a supramolecular bidentate P-ligand self-assembled through an acid-base interaction. A small library of chiral BINOL-derived monodentate phosphites containing either a carboxylic acid or a tertiary amine was synthesized in a few straightforward steps and in moderate to good yields. The ligand combinations were screened in the enantioselective rhodium-catalyzed hydrogenation of methyl 2-acetamidoacrylate. Selected heterocombinations of an amine-derived phosphite and of a carboxylic phosphite displayed a higher level of enantioselectivity compared to the corresponding homocombinations (up to 90% e.e.). The formation of the rhodium complexes was studied by IR- and 31P-NMR spectroscopy using both the single ligands (homocombinations) and the combinations of a carboxylic phosphite and a tertiary amine-derived phosphite (heterocombinations). In this way, the role of the acid-base interactions in determining the heterocomplex : homocomplexes ratios was investigated
Measuring Preferred Role Orientations for Patients and Providers in Veterans Administration and University General Medicine Clinics
Background Congruence between patients' and providers' preferred healthcare role orientations has been shown to be important for improved clinical outcomes and patient satisfaction. Thus, it is important to know how different patient and provider populations might vary in preferred role orientations. Abstract: ObjectiveObjective To measure the range of role orientation preferences among patients and providers in two different general medicine clinic populations. Abstract: MethodsMethods Role orientation preferences of patients (n - 319) and providers (n - 151) in six Veterans Administration (VA) primary care clinics and two university-based primary care clinics were measured in a cross sectional survey using the 9-item Patient-Practitioner Orientation Scale (PPOS) sharing subscale among patients and providers. Abstract: ResultsResults VA patients had lower mean PPOS scores (i.e. more provider-centered role preference) than the university clinic patients (31.2 vs 39.7, respectively; p < 0.001). The difference remained significant even after adjusting for age, sex, and education. VA and university clinic providers had similar mean PPOS scores (41.5 vs 42.6, respectively; p - 0.27). Greater differences were found in mean PPOS scores between VA patients and their providers (31.2 vs 41.5, respectively; p < 0.001) than university clinic patients and their providers (39.7 vs 42.6, respectively; p - 0.12). Abstract: ConclusionsConclusions VA patients reported preferences for a more provider-centered role than university clinic patients and there was greater mean difference in preferred role orientations between VA patients and their providers than between university clinic patients and their providers. Differences in preferred role orientations by patients and providers should be considered when designing clinical initiatives and research to improve patient care.

Interest of psychological interventions in dialysis: Exploratory Study
Patients suffering from end stage renal disease (ESRD) have a very reduced quality of life accompanied by a severe emotional distress (high worries-anxiety-depression). However, in Belgium, no regular psychological intervention is proposed to dialyzed patients. Our objective is to show that psychological intervention can significantly decrease the emotional distress of patients with ESRD.
Eleven sessions of structured interventions are proposed to ESRD patients. Eligibility criteria are to be major, to not present confusion or/and dementia, to have been on dialysis treatment for at least 3 months, to have obtained 14 or more on HAD-scale. Interventions carry on the management of anxious and depressive symptoms and of the disease itself. This constitutes three independent modules. Questionnaires are filled in by the patients at various stages to evaluate the anxiety and the depression (HADS), the worries (Penn State) and the quality of life (KDQoL-SF).
Results for the 47 ESRD patients show a significant reduction of the scores of anxiety, depression and worries and a significant growth of quality of life. In parallel a decrease in the serum calcium-phosphorus product analyzed before dialysis has been noted
The Relationship Between Beliefs About Sleep and Adherence to Behavioral Treatment Combined With Meditation for Insomnia
This study examined beliefs about sleep, as measured by the Dysfunctional Beliefs and Attitudes about Sleep (DBAS) scale, as predictors of adherence to 3 specific insomnia treatment recommendations: restriction of time spent in bed, maintenance of a consistent rise time, and completion of daily meditation practice. Higher DBAS scores predicted poorer adherence to restriction of time spent in bed and to maintenance of a prescribed rise time. DBAS scores were not associated with completion of daily meditation. These preliminary findings suggest that pre-treatment beliefs about sleep may impact patient engagement with behavioral recommendations regarding time in bed and consistent rise time during treatment for insomnia
