- Background: Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) carries a risk of sudden death. We aimed to assess whether vectorcardiographic (VCG) parameters directed toward the right heart and a measured angle of the S-wave would help differentiate ARVD/C with otherwise normal electrocardiograms from controls. Methods: Task Force 2010 definite ARVD/C criteria were met for all patients. Those who did not fulfill Task Force depolarization or repolarization criteria (-ECG) were compared with age and gender-matched control subjects. Electrocardiogram measures of a 3-dimentional spatial QRS-T angle, a right-precordial-directed orthogonal QRS-T (RPD) angle, a root mean square of the right sided depolarizing forces (RtRMS-QRS), QRS duration (QRSd) and the corrected QT interval (QTc), and a measured angle including the upslope and downslope of the S-wave (S-wave angle) were assessed. Results: Definite ARVD/C was present in 155 patients by 2010 Task Force criteria (41.7 ± 17.6 years, 65.2% male). -ECG ARVD/C patients (66 patients) were compared to 66 control patients (41.7 ± 17.6 years, 65.2% male). All parameters tested except the QRSd and QTc significantly differentiated -ECG ARVD/C from control patients (p < 0.004 to p < 0.001). The RPD angle and RtRMS-QRS best differentiated the groups. Combined, the 2 novel criteria gave 81.8% sensitivity, 90.9% specificity and odds ratio of 45.0 (95% confidence interval 15.8 to 128.2). Conclusion: ARVD/C disease process may lead to development of subtle ECG abnormalities that can be distinguishable using right-sided VCG or measured angle markers better than the spatial QRS-T angle, the QRSd or QTc, in the absence of Taskforce ECG criteria.

- Background: Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) carries risk of sudden death. We hypothesize that the S-wave angle differentiates ARVD/C with otherwise normal electrocardiograms from controls. Materials and methods: All patients met Task Force 2010 definite ARVD/C criteria. ARVD/C patients without Task Force depolarization/repolarization criteria (−ECG) were compared to controls. Electrocardiogram measures of QRS duration, corrected QT interval, and measured angle between the upslope and downslope of the S-wave in V2, were assessed. Results: Definite ARVD/C was present in 155 patients (42.7 ± 17.3 years, 68.4%male). −ECG ARVD/C patients (66 patients) were compared to 66 control patients (41.8 ± 17.6 years, 65.2%male). Only the S-wave angle differentiated −ECG ARVD/C patients from controls (<0.001) with AU the ROC curve of 0.77 (95%CI 0.53 to 0.71) and odds ratio of 28.3 (95%CI 6.4 to 125.5). Conclusion: ARVD/C may lead to development of subtle ECG abnormalities distinguishable using the S-wave angle prior to development of 2010 Taskforce ECG criteria.

Dilemmas in witnessing elder abuse in caregiving situations: A family member perspective
- 2009

Ingår i: Southern Online Journal of Nursing Research. - 1538-0696. ; 9:1

Tidskriftsartikel (refereegranskat)abstract
- Family members who witness elder abuse could be valuable partners to nurses and support personnel in case identification and intervention. The aim of this study was to explore an adult family member’s experiences of witnessing family situations of elder abuse. Interviews were conducted with a woman who had witnessed situations of elder abuse involving her uncle, his wife with disabilities, and health care personnel. Interviews were analyzed using van Manen’s thematic analysis and conception of narrative anecdotes, and development of poetic representations. The witness described conflictual feelings about her family and caregiving situation but felt there were no support personnel she could trust. She felt powerless and remained passive out of loyalty to family, need to protect family, and feeling shame that this was her family. Although she knew what she ought to do she could not live up to her ideals and instead tolerated escalating abuse. The family member witness viewed healthcare personnel as also tolerating and carrying responsibility for the abuse situation. For nurses and support personnel these findings point to the importance of personal and professional reflection and collegial discussions on morality, practice, what we see, and more importantly, what we do not see or want to see.

Elder abuse through a prism of perceptions : perspectives of potential witnesses
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to deepen understanding of elder abuse (EA) by exploring and comparing perceptions held by experts, older persons, representatives of potential support organizations, and family members. Experts’ perspectives (I) were examined through risk indicators and screening questions (a) located in EA literature and (b) selected by an international Delphi panel. Risk indicators most commonly found in the literature or selected by the panel were compiled into consensus lists. There were differences between risk indicators and questions in the two lists. In papers II and III participants were interviewed in focus groups about their perceptions of EA. Older persons (II) considered EA to be due to changing society and family systems where children are not brought up to respect older persons. EA was mainly conceptualized as ageism, criminal actions, mistreatment in residential care, and societal abuse. The abuser was perceived as a stranger or a healthcare worker. Fear was discussed as a major consequence of EA; especially fear among women. Abused persons were described as carrying the responsibility to seek help. Witnesses were described as hesitant to get involved. Improvements in society such as educating children and healthcare workers were considered ways to cope with EA. Besides family and friends there were few spontaneous suggestions for where to seek help and support in society. These suggestions included healthcare, police, church, and volunteer organizations. Representatives of these suggested organizations were interviewed in focus groups about their perceptions of EA (III). Perceptions of both causes and conceptions of EA were very similar to perceptions of older persons (II). Four themes emerged in the data; good intentions in abusive situations, older generation’s responsibility for EA, failing to report abuse, and prevention of abuse. Participants (III) also expressed ageist attitudes themselves and findings included victim blaming and tolerance for EA. Participants perceived that anyone could be provoked to abuse, and that abusers can be considered victims in abusive situations. Confidentiality was discussed as a barrier to reporting and the need for educating children to show respect for older persons was identified. Interviews with an adult family member (IV) explored her experiences of witnessing abuse situations between her uncle and his wife. In her desire to protect and remain loyal to her family she felt powerless and tolerated abuse. She longed for support she could trust but was locked into passivity by her feelings of shame. Synthesis of findings (I – IV) revealed issues of isolation, autonomy, vulnerability, victim blaming, perceiving the abuser as a victim of circumstances, ageism, tolerating EA, shame, and power as essential elements in EA. Based on the findings, alternative descriptions of EA are offered as a challenge to existing EA definitions. Findings suggest that a key to unlocking EA is compassion, understood as the ability to see a situation as if we were in it ourselves, experiencing the potential for disrespect, shame and unworthiness inherent in abusive acts.

- INTRODUCTION: Nephropatia epidemica (NE), a relatively mild form of hemorrhagic fever with renal syndrome caused by the Puumala virus (PUUV), is endemic in northern Sweden. We aim to study the risk factors associated with NE in this region.METHODS: We conducted a matched case-control study between June 2011 and July 2012. We compared confirmed NE cases with randomly selected controls, matched by age, sex, and place of infection or residence. We analyzed the association between NE and several occupational, environmental, and behavioral exposures using conditional logistic regression.RESULTS: We included in the final analysis 114 cases and 300 controls, forming 246 case-control pairs. Living in a house with an open space beneath, making house repairs, living less than 50 m from the forest, seeing rodents, and smoking were significantly associated with NE.CONCLUSION: Our results could orient public health policies targeting these risk factors and subsequently reduce the NE burden in the region.

Sex-dimorphic genetic effects and novel loci for fasting glucose and insulin variability

Tidskriftsartikel (refereegranskat)abstract
- Differences between sexes contribute to variation in the levels of fasting glucose and insulin. Epidemiological studies established a higher prevalence of impaired fasting glucose in men and impaired glucose tolerance in women, however, the genetic component underlying this phenomenon is not established. We assess sex-dimorphic (73,089/50,404 women and 67,506/47,806 men) and sex-combined (151,188/105,056 individuals) fasting glucose/fasting insulin genetic effects via genome-wide association study meta-analyses in individuals of European descent without diabetes. Here we report sex dimorphism in allelic effects on fasting insulin at IRS1 and ZNF12 loci, the latter showing higher RNA expression in whole blood in women compared to men. We also observe sex-homogeneous effects on fasting glucose at seven novel loci. Fasting insulin in women shows stronger genetic correlations than in men with waist-to-hip ratio and anorexia nervosa. Furthermore, waist-to-hip ratio is causally related to insulin resistance in women, but not in men. These results position dissection of metabolic and glycemic health sex dimorphism as a steppingstone for understanding differences in genetic effects between women and men in related phenotypes.

Large-scale migration into Britain during the Middle to Late Bronze Age
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Present-day people from England and Wales harbour more ancestry derived from Early European Farmers (EEF) than people of the Early Bronze Age1. To understand this, we generated genome-wide data from 793 individuals, increasing data from the Middle to Late Bronze and Iron Age in Britain by 12-fold, and Western and Central Europe by 3.5-fold. Between 1000 and 875 BC, EEF ancestry increased in southern Britain (England and Wales) but not northern Britain (Scotland) due to incorporation of migrants who arrived at this time and over previous centuries, and who were genetically most similar to ancient individuals from France. These migrants contributed about half the ancestry of Iron Age people of England and Wales, thereby creating a plausible vector for the spread of early Celtic languages into Britain. These patterns are part of a broader trend of EEF ancestry becoming more similar across central and western Europe in the Middle to Late Bronze Age, coincident with archaeological evidence of intensified cultural exchange2-6. There was comparatively less gene flow from continental Europe during the Iron Age, and Britain's independent genetic trajectory is also reflected in the rise of the allele conferring lactase persistence to ~50% by this time compared to ~7% in central Europe where it rose rapidly in frequency only a millennium later. This suggests that dairy products were used in qualitatively different ways in Britain and in central Europe over this period.
