Measurement with an automated oscillometric wrist device with position sensor leads to lower values than measurements obtained with an automated oscillometric arm device from the same manufacturer in elderly persons.

OBJECTIVE: Home blood pressure (BP) monitoring is recommended by several clinical guidelines and has been shown to be feasible in elderly persons. Wrist manometers have recently been proposed for such home BP measurement, but their accuracy has not been previously assessed in elderly patients. METHODS: Forty-eight participants (33 women and 15 men, mean age 81.3±8.0 years) had their BP measured with a wrist device with position sensor and an arm device in random order in a sitting position. RESULTS: Average BP measurements were consistently lower with the wrist than arm device for systolic BP (120.1±2.2 vs. 130.5±2.2 mmHg, P<0.001, means±SD) and diastolic BP (66.0±1.3 vs. 69.7±1.3 mmHg, P<0.001). Moreover, a 10 mmHg or greater difference between the arm and wrist device was observed in 54.2 and 18.8% of systolic and diastolic measures, respectively. CONCLUSION: Compared with the arm device, the wrist device with position sensor systematically underestimated systolic as well as diastolic BP. The magnitude of the difference is clinically significant and questions the use of the wrist device to monitor BP in elderly persons. This study points to the need to validate BP measuring devices in all age groups, including in elderly persons.

Does the working environment influence health care professionals' values, meaning in life and religiousness? Palliative care units compared with maternity wards.

CONTEXT: Increased altruism, self-transcendence, and quests for meaning in life (MiL) have been found in palliative care (PC) patients and their families who experience the finiteness of life. Similar changes were observed in healthy subjects who were experimentally confronted with their mortality. OBJECTIVES: The study investigated how daily experiences of the transitoriness of life influence PC health care professionals' (HCPs) values, MiL, and religiousness. METHODS: In a cross-sectional study, the Schwartz Value Survey, the Schedule for Meaning in Life Evaluation, and the Idler Index of Religiosity were used to investigate personal values, MiL, and private religiousness. HCPs working in PC (confronted with death) were compared with a control group of HCPs working at maternity wards (MWs) using multivariate models. Differences were considered to be statistically significant at P < 0.05. RESULTS: Seventy PC- and 70 MW-HCPs took part in the study (response rate 74.0%). No differences between the groups were found in overall MiL satisfaction scores. PC-HCPs were significantly more religious than MW-HCPs; they listed spirituality and nature experience more often as areas in which they experience MiL. Furthermore, hedonism was more important for PC-HCPs, and they had higher scores in openness-to-change values (stimulation and self-direction). MW-HCPs were more likely to list family as a MiL area. They assigned more importance to health and scored higher in conservation values (conformity and security). Duration of professional experience did not influence these results. CONCLUSION: Basic differences in values, MiL, and religiousness between PC-HCPs and MW-HCPs might have influenced the choice of working environment because no effect of job duration was observed. Longitudinal research is needed to confirm this hypothesis.

Clinical chemistry variables in normal elderly and healthy ambulatory populations: comparison with reference values.

Laboratory values of the most commonly assayed clinical chemistry variables were determined in selected elderly and healthy ambulatory populations. The upper and lower limits (2.5 and 97.5 fractiles) were compared with the adult reference values in use in university hospitals of Switzerland. The results suggest that conventional adult reference values can be used for most variables in the elderly and that these values are also useful in an ambulatory population.

Personality, social values, and marital satisfaction as predictors of parents’ rearing styles

Los estilos de crianza parentales pueden afectar la conducta y socialización de los adolescentes, por lo que es de interés conocer cómo algunas variables psicológicas de los padres se relacionan con los estilos de crianza. Este estudio tiene el objetivo de analizar los estilos de crianza de los padres, valores sociales (prestigio social, orden, benevolencia, y conservadurismo-liberalismo), los cinco grandes factores de personalidad, y la satisfacción de pareja (acuerdo general, afecto, satisfacción, y cohesión) en los padres de adolescentes. Este es un estudio prospectivo basado en método de análisis correlacional. Se encontró que los estilos educativos definidos por el cariño y aceptación se relacionan con los rasgos de personalidad como responsabilidad y estabilidad emocional, alta satisfacción de pareja y preferencia por valores prosociales. Al contrario, los estilos de crianza de sobreprotección y favoritismo se relacionan con baja amabilidad y baja apertura el poco ajuste de pareja con falta de cohesión y valores sociales definidos por falta de benevolencia y preferencia por valores de prestigio social.

Low C-reactive protein values at admission predict mortality in patients with severe community-acquired pneumonia caused by Streptococcus pneumoniae that require intensive care management.

PURPOSE: To identify risk factors associated with mortality in patients with severe community-acquired pneumonia (CAP) caused by S. pneumoniae who require intensive care unit (ICU) management, and to assess the prognostic values of these risk factors at the time of admission. METHODS: Retrospective analysis of all consecutive patients with CAP caused by S. pneumoniae who were admitted to the 32-bed medico-surgical ICU of a community and referral university hospital between 2002 and 2011. Univariate and multivariate analyses were performed on variables available at admission. RESULTS: Among the 77 adult patients with severe CAP caused by S. pneumoniae who required ICU management, 12 patients died (observed mortality rate 15.6 %). Univariate analysis indicated that septic shock and low C-reactive protein (CRP) values at admission were associated with an increased risk of death. In a multivariate model, after adjustment for age and gender, septic shock [odds ratio (OR), confidence interval 95 %; 4.96, 1.11-22.25; p = 0.036], and CRP (OR 0.99, 0.98-0.99 p = 0.034) remained significantly associated with death. Finally, we assessed the discriminative ability of CRP to predict mortality by computing its receiver operating characteristic curve. The CRP value cut-off for the best sensitivity and specificity was 169.5 mg/L to predict hospital mortality with an area under the curve of 0.72 (0.55-0.89). CONCLUSIONS: The mortality of patients with S. pneumoniae CAP requiring ICU management was much lower than predicted by severity scores. The presence of septic shock and a CRP value at admission <169.5 mg/L predicted a fatal outcome.

Effect of humic substances and weather conditions on leaf biochemical changes of fertigated guava tree, during orchard establishment

In São Francisco Valley, Northeast Brazil, humic substances have been used by growers in fertigated fruit crops, due to its improvements on soil conditions and in plant nutrient uptake, metabolism and growth, reported from different growing places and crops. Nevertheless, little information about plant response to humic substance usage for local soil, weather and cropping system conditions is known. Hence, the metabolic response of guava tree during the orchard establishment to fertigation with humic substances and its correlation to the weather conditions were evaluated in Petrolina, State of Pernambuco. The treatments were manure application in soil combined with mineral fertilizers and humic substances applied through water of irrigation. The results showed that the fertigation treatments and plant age did not present conclusive effects in guava leaf contents of carbohydrates, proteins and amino acids. On the other side, the leaf contents of these compounds were influenced by the weather conditions.

Biochemical treatment of brown grade rejects in recycling process

Ruskeisiin kierrätysmassoihin kuuluu kulutuksen kannalta tärkeimpänä laatuna OCC (old corrugated containers). OCC sisältää noin 70-100% aaltopahvia eli pääasiassa se koostuu valkaisemattomasta kemiallisesta massasta. OCC uusiomassan ensisijainen käyttökohde on aaltopahvin valmistus. OCC:n kierrätyskuituprosessissa syntyy merkittäviä määriä rejektiä. Rejektin määrä riippuu paljolti kierrätettävän materiaalin laadusta ja puhtaudesta, mutta myös tulevan massan käyttötarkoituksesta sekä prosessiolosuhteista. OCC-prosessissa rejektoituvan aineksen määrä voi nousta korkeaksi, mikäli kierrätettävä materiaali sisältää märkälujaliimoja tai muuten raskaasti liimattuja komponentteja sekä runsaasti kontaminantteja, kuten muoveja, teippejä ja metalleja. Keskimäärin OCC-rejekti sisältää 30-60% kiinteää ainesta, 30-90% (kuivapaino) kuituja, 5-70% (kuivapaino) muoveja ja 1-10% (kuivapaino) tuhkaa. Syntynyt rejekti voidaan polttaa energiaksi tai käyttää maantäyttöaineena. Harvinaisempia sovelluksia rejektin käsittelyssä ovat rejektin kuitujen talteenotto uudelleenprosessointia varten tai alkoholin ja levuliinihapon tuottamiseen. Rejektin asianmukaisella käsittelyllä voidaan vähentää kaatopaikkakustannuksia, sekä parantaa kierrätysprosessin tuottavuutta. Tämän työn tarkoituksena oli tutkia biokemiallisen käsittelyn mahdollisuudet OCC-rejektin hajotuksessa. Alustavissa laboratoriomittakaavan kokeissa etsittiin sopiva käsittelytapa, joka toteutettiin sitten pilot plant -mittakaavassa. Tulokset osoittavat, että biokemiallisen käsittelyn avulla rejekti voidaan hajottaa jolloin jätteenkäsittelykustannukset pienenevät ja kierrätyskuituprosessin taloudellisuus paranee.

HRM Practices Sustaining PSM: When Values Congruency Matters

Abstract: This study aims at identifying the organisational antecedents of public service motivation (PSM). It focuses on human resources management (HRM) practices as one category of organisational factors that impact on PSM. Concretely, this research questions how intrinsic and extrinsic HRM practices are related to PSM and whether these relationships are direct or mediated by person-organisation (P-O) fit. The empirical findings are based on a survey of 6,885 civil servants working in Switzerland. Regression analyses highlight that intrinsic HRM practices are positively related to PSM, whereas extrinsic ones are negatively related to PSM. Furthermore, mediation tests shows that only the intrinsic HRM practices are mediated by PO fit. Thus, civil servants who value intrinsic work incentives maintain a high PSM level when they perceive congruence between their individual expectations and the values of their organisation.
