The power of social connection and support in improving health: lessons from social support interventions with childbearing women

<p>Abstract</p> <p>Background and objective</p> <p>Social support interventions have a somewhat chequered history. Despite evidence that social connection is associated with good health, efforts to implement interventions designed to increase social support have produced mixed results. The aim of this paper is to reflect on the relationship between social connectedness and good health, by examining social support interventions with mothers of young children and analysing how support was conceptualised, enacted and valued, in order to advance what we know about providing support to improve health.</p> <p>Context and approach</p> <p>First, we provide a brief recent history of social support interventions for mothers with young children and we critically examine what was intended by ‘social support’, who provided it and for which groups of mothers, how support was enacted and what was valued by women. Second, we examine the challenges and promise of lay social support approaches focused explicitly on companionship, and draw on experiences in two cluster randomised trials which aimed to improve the wellbeing of mothers. One trial involved a universal approach, providing befriending opportunities for all mothers in the first year after birth, and the other a targeted approach offering support from a ‘mentor mother’ to childbearing women experiencing intimate partner violence.</p> <p>Results</p> <p>Interventions providing social support to mothers have most often been directed to women seen as disadvantaged, or ‘at risk’. They have also most often been enacted by health professionals and have included strong elements of health education and/or information, almost always with a focus on improving parenting skills for better child health outcomes. Fewer have involved non-professional ‘supporters’, and only some have aimed explicitly to provide companionship or a listening ear, despite these aspects being what mothers receiving support have said they valued most. Our trial experiences have demonstrated that non-professional support interventions raise myriad challenges. These include achieving adequate reach in a universal approach, identification of those in need of support in any targeted approach; how much training and support to offer befrienders/mentors without ‘professionalising’ the support provided; questions about the length of time support is offered, how ‘closure’ is managed and whether interventions impact on social connectedness into the future. In our two trials what women described as helpful was not feeling so alone, being understood, not being judged, and feeling an increased sense of their own worth.</p> <p>Conclusion and implications</p> <p>Examination of how social support has been conceptualised and enacted in interventions to date can be instructive in refining our thinking about the directions to be taken in future research. Despite implementation challenges, further development and evaluation of non-professional models of providing support to improve health is warranted.</p

Postpartum anxiety, depression and social health: findings from a population-based survey of Australian women

<p>Abstract</p> <p>Background</p> <p>Whilst the prevalence and correlates of postpartum depression are well established, far less is known about postpartum anxiety. Studies have described the association between socio-demographic factors and postpartum depression, yet few have explored the association between stressors in women's lives around the time of having a baby and maternal psychological morbidity. This study aimed to describe the population prevalence of postpartum depression, anxiety, co-morbid anxiety and depression and social health issues; and to examine the association between postpartum psychological and social health issues experienced in the six months following birth.</p> <p>Methods</p> <p>Population-based survey of all women who gave birth in Victoria and South Australia in September/October 2007. Women were mailed the survey questionnaire six months following birth. Anxiety and depression were measured using the Depression Anxiety Stress Scales (DASS-21).</p> <p>Results</p> <p>Questionnaires were completed by 4,366 women. At six months postpartum the proportion of women scoring above the 'normal' range on the DASS-21 was 12.7% for anxiety,17.4% for depression, and 8.1% for co-morbid depression and anxiety. Nearly half the sample reported experiencing stressful life events or social health issues in the six months following birth, with 38.3% reporting one to two and 8.8% reporting three or more social health issues. Women reporting three or more social health issues were significantly more likely to experience postnatal anxiety (Adj OR = 4.12, 95% CI 3.0-5.5) or depression (Adj OR = 5.11, 95% CI = 3.9-6.7) and co-morbid anxiety <it>and </it>depression (Adj OR = 5.41, 95% CI 3.8-7.6) than women who did not report social health issues.</p> <p>Conclusions</p> <p>Health care providers including midwives, nurses, medical practitioners and community health workers need to be alert to women's social circumstances and life events experienced in the perinatal period and the interplay between social and emotional health. Usual management for postpartum mental health issues including Cognitive Behavioural Therapy and pharmacological approaches may not be effective if social health issues are not addressed. Coordinated and integrated perinatal care that is responsive to women's social health may lead to improvements in women's emotional wellbeing following birth.</p

Non-Invasive Genetic Sampling of Faecal Material and Hair from the Grey-Headed Flying-Fox (Pteropus poliocephalus)

Remote-sampling DNA from animals offers obvious benefits for species that are difficult to sample directly and is less disruptive for species of conservation concern. Here we report the results of a pilot study investigating non-invasive DNA sampling of the grey-headed flying-fox (Pteropus poliocephalus), a threatened species that is restricted to the east coast of Australia. We successfully extracted DNA from fresh scats and hair, each of which was of sufficient quality for amplifying mitochondrial DNA markers and microsatellites. A single-locus multitube approach was used to investigate amplification success and genotyping reliability. Faecal samples yielded a higher proportion of successful amplifications and consensus genotype assignments than hair samples. We outline measures that may be utilised to minimise microsatellite genotyping error for future studies. These indirect approaches to obtaining genetic data show much promise given the difficult nature of directly sampling flying-foxes and related species

Creating a Professional Development Plan for a Simulation Consortium

As the United States struggles with health care reform and a nursing education system that inadequately prepares students for practice, dramatic advances in educational technology signal opportunities for both academic and practicing nurses to affect our profession as never before. Simulation technologies provide large and small institutions with the means to educate health care students and novice professionals effectively and efficiently through hands-on experience, but the costs of such a venture can be prohibitive. A simulation consortium offers a venue for different health care and educational institutions with shared goals to pool knowledge, monies, and labor toward health care education throughout a geographic area. This article details one Midwestern U.S. region's work in creating a professional development plan for a new simulation consortium

A feasibility study of a brief psycho-educational intervention for psychogenic nonepileptic seizures

AbstractPurposeWe have previously reported that one in six patients stops experiencing psychogenic nonepileptic seizures (PNES) following our communication protocol. This prospective multicentre study describes a psycho-educational intervention for PNES building on the initial communication of the diagnosis and examines the feasibility of its delivery by healthcare professionals with minimal experience in psychological therapies.MethodThree healthcare professionals with minimal training in psychological therapies took part in a one-day training course. 20 participants attended for a four-session manualised psycho-educational intervention delivered at three different clinical neuroscience centres. Participants completed self-report measures prior to the intervention at baseline (n=29) and seven months after diagnosis (n=13) measures included seizure frequency, health related quality of life, healthcare utilisation, activity levels, symptom attributions and levels of functioning. Therapy sessions were audiorecorded and manual adherence assessed.ResultsOf 29 patients enrolled into the study, 20 started and 13 completed the intervention and provided follow-up information. At follow-up, 4/13 of patients had achieved complete seizure control and a further 3/13 reported a greater than 50% improvement in seizure frequency. After training, epilepsy nurses and assistant psychologists demonstrated sufficient adherence to the manualised psycho-educational intervention in 80% of sessions.ConclusionThe delivery of our brief manualised psycho-educational intervention for PNES by health professionals with minimal training in psychological treatment was feasible. The intervention was associated with higher rates of PNES cessation than those observed in our previous studies describing the short-term outcome of the communication of the diagnosis alone. An RCT of the intervention is justified but a significant proportion of drop-outs will have to be anticipated

Adult helpers increase the recruitment of closely related offspring in the cooperatively breeding rifleman

Indirect fitness benefits gained through kin-selected helping are widely invoked to explain the evolution of cooperative breeding behavior in birds. However, the impact of helpers on productivity of helped broods can be difficult to determine if the effects are confounded by territory quality or if the benefit of helpers is apparent only in the long term. In riflemen Acanthisitta chloris, helping and group membership are effectively decoupled as adult helpers are individuals that have dispersed from their natal territory and live independently from breeders in “kin neighborhoods.” Nevertheless, helpers direct their care toward close relatives, suggesting that helping provides indirect fitness benefits. The aim of this study was to examine the benefits of helpers to recipient offspring in the rifleman, investigating both short- and long-term effects. The total amount of food delivered to nestlings in helped broods was greater than that received by broods without helpers. This did not result in any short-term increase in nestling mass or nestling body condition nor was there any reduction in length of the nestling period at helped nests. However, helpers were associated with a significant increase in juvenile recruitment, with twice the proportion of fledglings surviving to the next breeding season from helped broods relative to unhelped broods. Thus, helpers gain indirect fitness by improving the survival of kin, and in contrast to a previous study of riflemen, we conclude that kin selection has played a key role in the evolution of cooperative breeding in this species

Changes in fetal mannose and other carbohydrates induced by a maternal insulin infusion in pregnant sheep

BACKGROUND: The importance of non-glucose carbohydrates, especially mannose and inositol, for normal development is increasingly recognized. Whether pregnancies complicated by abnormal glucose transfer to the fetus also affect the regulation of non-glucose carbohydrates is unknown. In pregnant sheep, maternal insulin infusions were used to reduce glucose supply to the fetus for both short (2-wk) and long (8-wk) durations to test the hypothesis that a maternal insulin infusion would suppress fetal mannose and inositol concentrations. We also used direct fetal insulin infusions (1-wk hyperinsulinemic-isoglycemic clamp) to determine the relative importance of fetal glucose and insulin for regulating non-glucose carbohydrates. RESULTS: A maternal insulin infusion resulted in lower maternal (50%, P < 0.01) and fetal (35-45%, P < 0.01) mannose concentrations, which were highly correlated (r(2) = 0.69, P < 0.01). A fetal insulin infusion resulted in a 50% reduction of fetal mannose (P < 0.05). Neither maternal nor fetal plasma inositol changed with exogenous insulin infusions. Additionally, maternal insulin infusion resulted in lower fetal sorbitol and fructose (P < 0.01). CONCLUSIONS: Chronically decreased glucose supply to the fetus as well as fetal hyperinsulinemia both reduce fetal non-glucose carbohydrates. Given the role of these carbohydrates in protein glycosylation and lipid production, more research on their metabolism in pregnancies complicated by abnormal glucose metabolism is clearly warranted

Characterization of muscle in OI Model mice

Abstract only availableOsteogenesis imperfecta (OI) is a congenital connective tissue disorder characterized by decreased bone mineral density and increased bone fragility and susceptibility to fracture. In addition to skeletal fragility, patients with OI reportedly have muscle weakness although currently no systematic evaluation of muscle function or morphology in humans or animal models of the disease has been performed. Normal type I collagen is coded for two genes located on different chromosomes: COL1A1 and COL1A2. The oim/oim mouse is homozygous for a null mutation in the COL1A2 gene and is a phenocopy of human type III OI (severe disease phenotype). Heterozygous mice (oim/+) harbor the null mutation in only one allele of the COL1A2 gene and model human patients with type I OI (mild disease phenotype). We wanted to determine whether the reported muscle weakness in OI patients is due to a muscle pathology. We analyzed the muscle mass, fiber morphology, and cross-sectional area of muscles fibers of the hind limb muscles (quadriceps, gastrocnemius, plantaris, tibialis anterior and soleus), as well as the fiber type composition of the soleus muscle of wildtype (wt), heterozygous (oim/+), and homozygous (oim/oim) mice. Our results demonstrate that the muscle mass/body mass, fiber morphology, cross-sectional area of hindlimb muscles, as well as fiber type composition of the soleus muscle of oim, oim/+ relative to wt (+/+) mouse muscles were not significantly different between the genotypes. We correlated our morphologic findings with a functional contractile assay and determined that muscle tension-force generation and nerve conduction are not impaired in oim/oim or oim/+ mice. These findings suggest that oim and oim/+ mice do not have inherent muscle pathology. This knowledge is important in our ultimate understanding of skeletal muscle in OI model mice and ultimately, humans with this disease.Life Sciences Undergraduate Research Opportunity Progra
