Family close but friends closer: exploring social support and resilience in older spousal dementia carers
© 2016 Informa UK Limited, trading as Taylor & Francis GroupObjectives: Spousal dementia carers have unique support needs; they are likely to disengage from their existing social networks as they need to devote more time to caring as the disease progresses. Previously we showed that support resources can facilitate resilience in carers, but the relationship is complex and varies by relationship type. The current paper aims to explore social support as a key component of resilience to identify the availability, function and perceived functional aspects of support provided to older spousal dementia carers. Method: We conducted 23 in-depth qualitative interviews with spousal carers from two carer support groups and a care home in North West England. Results: Family and friends served a wide range of functions but were equally available to resilient and non-resilient participants. Family support was perceived as unhelpful if it created feelings of over-dependence. Participants were less likely to resist involvement of grandchildren due to their relatively narrow and low-level support functions. Friend support was perceived as most helpful when it derived from those in similar circumstances. Neighbours played a functionally unique role of crisis management. These perceptions may moderate the effect of support on resilience. Conclusion: Family and friend support is not always sufficient to facilitate resilience. Support functions facilitate resilience only if they are perceived to match need. Implications of these findings are discussed
The Emotional and Practical Experiences of Formula-Feeding Mothers
The majority of infant‐feeding research is focused on identifying mother's reasons for the cessation of breastfeeding. The experience of mothers who choose to use formula is largely overlooked in quantitative designs. This study aimed to describe the emotional and practical experiences of mothers who formula feed in any quantity, and examine whether these experiences would vary among different cohorts of formula‐feeding mothers according to prenatal feeding intention and postnatal feeding method. A total of 890 mothers of infants up to 26 weeks of age, who were currently formula feeding in any quantity, were recruited through relevant international social media sites via advertisements providing a link to an online survey. Predictors of emotional experiences included guilt, stigma, satisfaction, and defense as a result of their infant feeding choices. Practical predictor variables included support received from health professionals, respect displayed by their everyday environment, and main sources of infant feeding information. Descriptive findings from the overall sample highlighted a worryingly high percentage of mother's experienced negative emotions as a result of their decision to use formula. Multinomial logit models revealed that negative emotions such as guilt, dissatisfaction, and stigma were directly associated with feeding intention and method. The evidence suggests that the current approach to infant‐feeding promotion and support may be paradoxically related to significant issues with emotional well‐being. These findings support criticisms of how infant‐feeding recommendations are framed by health care professionals and policy makers, and highlight a need to address formula feeding in a more balanced, woman‐centered manner
Scaling of Entanglement close to a Quantum Phase Transitions
In this Letter we discuss the entanglement near a quantum phase transition by
analyzing the properties of the concurrence for a class of exactly solvable
models in one dimension. We find that entanglement can be classified in the
framework of scaling theory. Further, we reveal a profound difference between
classical correlations and the non-local quantum correlation, entanglement: the
correlation length diverges at the phase transition, whereas entanglement in
general remains short ranged.Comment: 4 pages, 4 figures, revtex. Stylistic changes and format modifie
Assessing pet owner and veterinarian perceptions of need for veterinary compounding services in a community pharmacy setting
Background: Pets, pet owners (referred to as clients in veterinary medicine and throughout this article), veterinarians, and community pharmacies may all benefit from veterinary compounding services provided in community pharmacies, but the benefits of this service are not well-documented in the literature.
Objectives: This study identified perceived benefits and barriers and evaluated the need for veterinary compounding services in community pharmacies; it also evaluated current business practices related to veterinary compounding services.
Methods: A cross-sectional survey was administered to three groups: 1) clients who filled a pet prescription at a study pharmacy, 2) clients who had not filled pet prescriptions, and 3) local veterinarians. Eligible participants were 18 or older; clients must have owned a pet in the past five years. The surveys collected demographic information and assessed benefits, barriers, need, and business practices regarding veterinary compounding services. Demographics were evaluated through descriptive statistics. Responses to Likert-scale items were compared between groups using the Mann-Whitney U test. Qualitative responses were assessed for emerging themes.
Results: One hundred eighteen clients and 15 veterinarians participated in the study. Seventy-two of 116 clients (62%) and eight of 10 veterinarians (80%) agreed that clients would benefit from veterinary compounds provided in community pharmacies. Only 40% of veterinarians agreed that community pharmacists have the knowledge to compound pet medications, compared to 67% of clients (P=0.010). Similarly, 47% of veterinarians agreed that community pharmacists have the skills to compound pet medications, compared to 72% of clients (P=0.016). Forty-eight of 118 clients (41%) would travel 10 miles or more out of their way for veterinary compounding services at community pharmacies.
Conclusions: This study assessed client and veterinarian perceptions of veterinary compounding service benefits, barriers, and need in community pharmacies. Clients identified more opportunities for veterinary compounding services in community pharmacies when compared to veterinarians. Both groups identified a need for veterinary compounding services and agreed community pharmacies providing these services would benefit pets and clients
Subbarrel patterns in somatosensory cortical barrels can emerge from local dynamic instabilities
Complex spatial patterning, common in the brain as well as in other biological systems, can emerge as a result of dynamic interactions that occur locally within developing structures. In the rodent somatosensory cortex, groups of neurons called "barrels" correspond to individual whiskers on the contralateral face. Barrels themselves often contain subbarrels organized into one of a few characteristic patterns. Here we demonstrate that similar patterns can be simulated by means of local growth-promoting and growth-retarding interactions within the circular domains of single barrels. The model correctly predicts that larger barrels contain more spatially complex subbarrel patterns, suggesting that the development of barrels and of the patterns within them may be understood in terms of some relatively simple dynamic processes. We also simulate the full nonlinear equations to demonstrate the predictive value of our linear analysis. Finally, we show that the pattern formation is robust with respect to the geometry of the barrel by simulating patterns on a realistically shaped barrel domain. This work shows how simple pattern forming mechanisms can explain neural wiring both qualitatively and quantitatively even in complex and irregular domains. © 2009 Ermentrout et al
Relationships of the Psychological Influence of Food and Barriers to Lifestyle Change to Weight and Utilization of Online Weight Loss Tools
Abstract: Introduction: The psychological influence of food (PFS) and perceived barriers to lifestyle change (PBLC) were considered as predictors of body mass index and website tool utilization (TU) in an online weight loss program. Materials and Methodology: An archival analysis of all (N = 1361) overweight/obese (BMI M = 31.6 + 6.24 kg/m 2), adult (M = 42.0 + 10.72 years) users (82.4 % female) of an evidence-based, multidisciplinary Internet weight loss program was performed. Predictor variables included: PFS and PBLC, age, and longest maintained weight loss in relation to 1) BMI 2
Anxiety, depression, traumatic stress and COVID-19-related anxiety in the UK general population during the COVID-19 pandemic
BACKGROUND: The COVID-19 pandemic has created an unprecedented global crisis, necessitating drastic changes to living conditions, social life, personal freedom and economic activity. No study has yet examined the presence of psychiatric symptoms in the UK population under similar conditions.
AIMS:
We investigated the prevalence of COVID-19-related anxiety, generalised anxiety, depression and trauma symptoms in the UK population during an early phase of the pandemic, and estimated associations with variables likely to influence these symptoms.
METHOD:
Between 23 and 28 March 2020, a quota sample of 2025 UK adults aged 18 years and older, stratified by age, gender and household income, was recruited by online survey company Qualtrics. Participants completed standardised measures of depression, generalised anxiety and trauma symptoms relating to the pandemic. Bivariate and multivariate associations were calculated for demographic and health-related variables.
RESULTS:
Higher levels of anxiety, depression and trauma symptoms were reported compared with previous population studies, but not dramatically so. Anxiety or depression and trauma symptoms were predicted by young age, presence of children in the home, and high estimates of personal risk. Anxiety and depression were also predicted by low income, loss of income and pre-existing health conditions in self and others. Specific anxiety about COVID-19 was greater in older participants.
CONCLUSIONS:
This study showed a modest increase in the prevalence of mental health problems in the early stages of the pandemic, and these problems were predicted by several specific COVID-related variables. Further similar surveys, particularly of those with children at home, are required as the pandemic progresses
Regulatory and metabolic rewiring during laboratory evolution of ethanol tolerance in E. coli
We have designed an experimental/computational framework for studying complex phenotypes in bacteria.Our framework relies on whole-genome fitness profiling coupled with a module-level analysis to discover pathways that directly affect fitness.As a proof-of-principle, we studied ethanol tolerance in Escherichia coli and we identified key pathways that contribute to this phenotype.We then validated our findings through genetic manipulations, gene-expression profiling, metabolite-level measurements, and stable-isotope labeling
