Abstract [en]

Purpose – The purpose of this paper is to highlight the complexity surrounding the implementation of advanced electronic tracking, communication and emergency response technologies, namely, an extended safety and support (ESS) system for people with dementia (pwd) living at home. Results are presented from a Swedish demonstration study (2011-2012) conducted in 24 municipalities. Design/methodology/approach – It is a descriptive intervention study with a pre-post test design. Questionnaires were administered to pwd, carers and professionals at the outset and eight months later. ESS logging data were analyzed. Findings – ESS usage rates varied widely. A total of 650 alerts were triggered, mainly when the pwd was outdoors. Activities were reduced amongst pwd, most likely due to a progression of their disease. Carers noted that pwd were more independent than previously on those occasions when they engaged in outdoor activities. Staff considered that nearly half of pwd could remain living at home due to the ESS, compared with a third amongst carers. In total, 50 per cent of carers felt it was justified to equip their relative with an ESS without their explicit consent, compared to one in eight staff. Research limitations/implications – A limitation is the amount of missing data and high drop- out rates. Researchers should recruit pwd earlier in their illness trajectory. A mixed-methods approach to data collection is advisable. Practical implications – Carers played a crucial role in the adoption of ESS. Staff training/supervision about assistive devices and services is recommended. Social implications – Overall, use of ESS for pwd living at home was not an ethical problem. Originality/value – The study included key stakeholder groups and a detailed ethical analysis was conducted.

Abstract [en]

Traffic is regarded as the main reason for the air pollution problem and it seems obvious to try to reduce the particulate bioload affecting those travelling. Recently Volvo Cars introduced their Interior Air Quality System forcing the cabin air to be recirculated in case of a high level of noxious gases shutting out carbon monoxide, ground-level ozone and nitrogen dioxide. Ionization is another component of Mercedes AIR-BALANCE package. Considering the fact that it is the nano-size ultra-fine particles (UFP) that are known to cause the “oxidative” stress of the immune system one may ask if even the most well designed HEPA filter would sufficiently affect the in-cabin air particulates or is there a need for additional means by which the sub-micron class particles may be captured. An electrostatic field of sufficient strength may serve as an additional tool to clean the cabin air from sub-micron size particles.The initial data from the study indicate that electrostatic mechanisms substantially add to the in-cabin air cleaning properties of ultra-fine particulates compared to the standard filtering technology when recirculating the cabin air.

Abstract [en]

Purpose: The saltatory pattern, characterized by wide and rapid oscillations of the fetal heart rate (FHR), remains a controversial entity. The authors sought to evaluate whether it could be associated with an adverse fetal outcome. Material and Methods: The authors report a case series of four saltatory patterns occurring in the last 30 minutes before birth in association with cord artery metabolic acidosis, obtained from three large databases of internally acquired FHR tracings. The distinctive characteristics of this pattern were evaluated with the aid of a computer system. Results: All cases were recorded in uneventful pregnancies, with normal birth weight singletons, born vaginally at term. The saltatory pattern lasted between 23 and 44 minutes, exhibited a mean oscillatory amplitude of 45.9 to 80.0 beats per minute (bpm) and a frequency between four and eight cycles per minute. Conclusions: A saltatory pattern exceeding 20 minutes can be associated with the occurrence of fetal metabolic acidosis.

Abstract [en]

The development of a patented polymer based electron emitting technology (EAC) has provided a means to study the impact of reduced bioload in stable air on productivity. Apart from capturing particles in a negatively charged electrostatic field operating over the entire stable with hundreds of meters of emitting structure, the electrons combine with oxygen and vapor to produce H2O2 to block mould metabolism. Before and after data from three egg producing farms with 20-50 000 free-roaming layers were collected as part of their standard productivity control. The number of mould colonies decreased from >7 (range 7 – 30) to single colonies. Lay percentage over the production period covering 22 to 75 weeks of age increased by 3% and the feed conversion improved by 9%. During the last 10 production weeks, the overall improvement in productivity was 27% enabling the farmers to maintain a high productivity despite an ageing population of layers.

Abstract [en]

OBJECTIVE: To determine the association between 5-min Apgar score and umbilical cord artery carbon dioxide tension (pCO₂). DESIGN: Observational study. SETTING: European hospital labor wards. POPULATION: Data from 36,432 newborns ≥36 gestational weeks were obtained from three sources: two trials of monitoring with fetal electrocardiogram (the Swedish randomized controlled trial and the European Union Fetal ECG trial) and Mölndal Hospital data. After validation of the acid-base values, 25,806 5-min Apgar scores were available for analysis. METHODS: Validation of the umbilical cord acid-base values was performed to obtain reliable data. 5-min Apgar score was regressed against cord artery pCO₂ in a polynomial multilevel model. MAIN OUTCOME MEASURES: Five-min Apgar score, umbilical cord pCO₂, pH, and base deficit. RESULTS: Overall, a higher cord artery pCO₂ was found to be associated with lower 5-min Apgar scores. However, among newborns with moderate acidemia, lower umbilical cord artery pCO₂ (≤median pCO₂ for the specific cord artery pH) was associated with lower 5-min Apgar scores, with a relative risk of 2.0 (95% confidence interval: 1.4-2.8) for 5-min Apgar scores 0-6. CONCLUSIONS: Metabolic acidosis affects the newborn's vitality more than respiratory acidosis. In addition, elevated levels of pCO₂ may be beneficial for fetuses with moderate acidemia, and thus cord artery pCO₂ is a factor that should be considered when assessing the compromised newborn.

Abstract [en]

Background: Objective information on speci fi c fetal heart rate (FHR) parameters would be advantageous when assessing fetal responses to hypoxia. Small, visually undetectable changes in FHR variability can be quanti fi ed by power spectral analysis of FHR variability. Aims: To investigate the effect of intrapartum hypoxia and acidemia on spectral powers of FHR variability. Study design: This is a retrospective observational clinical study with data from an EU multicenter project. Subjects: We had 462 fetuses with a normal pH-value (pH > 7.20; controls) in fetal scalp blood sample (FBS) and 81 fetuses with a low scalp pH-value ( ≤ 7.20; low-FBS pH-fetuses). The low-FBS pH-fetuses were further divided into two subgroups according to the degree of acidemia: fetuses with FBS pH 7.11 – 7.20 (n = 58) and fetuses with FBS pH ≤ 7.10 (n = 23). Outcome measures: Spectral powers of FHR variability in relation to the concomitant FBS pH-value. Results: Fetuses with FBS pH ≤ 7.20 had increased spectral powers of FHR variability compared with controls (2.49 AU vs. 2.23 AU; p = 0.038). However, the subgroup of most affected fetuses (those with FBS pH ≤ 7.10) had signi fi cantly lower FHR variability spectral powers when compared to fetuses with FBS pH 7.11 – 7.20. Conclusions: This study shows that spectral powers of FHR variability change as a fetus becomes hypoxic, and that spectral powers decrease with deepening fetal acidemia.

Abstract [sv]

För kommunerna utgör kostnaderna för personer med demenssjukdom mer än 40 procent av deras totala kostnader för vård och omsorg och vi vet att samhällets insats förväntas öka framgent. Risken är att resurserna inte kommer att räcka till för att bevara en optimal livskvalité. Ett sätt att möta detta är att utnyttja olika tekniska lösningar. Mobila trygghetslarm är en möjliggörande teknologi med stor potential. Huvudsyftet med studien var att se på vilken grund mobila trygghetslarm kan vara ett verktyg som utvecklar vården och omsorgen för personer med demenssjukdom och underlättar för deras familjer i den dagliga tillvaron. Studien fokuserade på personer med demenssjukdom i eget boende.
