Exploring long-term outcomes of a peer support programme for parents* of children with disability in Australia

Peer support groups can offer parents of children with disability, positive well-being outcomes. Peer support groups not only provide opportunities for connections with others with similar experiences but also provide resources and information, emotional support, a sense of belonging and may help reduce stress and isolation. Peer support groups are an established form of support existing within family centred practice. However, it is unclear whether peer support groups achieve the outcomes that they aim to deliver. Further, little is known about the longer-term outcomes for parents attending such groups. This study aimed to explore the medium- and long-term outcomes and experiences of parents who participated in a peer support programme (the Now and Next programme) for parents of children with disability. Well-being data were collected at three timepoints (Ts): prior to commencing the programme (T1), immediately after completion of the programme (T2) and 6-30 months after completion of the programme (T3). Results of the study showed empowerment and well-being improved from T1 to T2, with gains maintained at T3. Hope scores did not significantly change over time. Participants continued to set and achieve goals over time using resources from the programme. Improvements in parents' well-being and empowerment scores were maintained in the longer-term. Our study contributes to evidence confirming sustained long-term outcomes of peer support programmes and demonstrates that building parent capacity, empowerment and well-being has a lasting effect on the parents of children with disability.

Effectiveness of peer support programmes for improving well-being and quality of life in parents/carers of children with disability or chronic illness: A systematic review

AIM

This systematic review synthesized quantitative evidence from the past decade of the effectiveness of peer support programmes in improving the well-being and/or quality of life (QoL) for parents/carers of children with disability/chronic illnesses.

BACKGROUND

For children with disability or chronic illness, parents/carers are critical in enabling or limiting their child's development. The parent's/carer's ability to provide the necessary responsive and structured care is impacted by several factors, including their own personality, skills, resources and well-being. Peer support programmes often aim to build parent/carer and/or family capabilities. Although studies and reviews have found positive benefits arising from such programmes, the impact of such programmes, specifically on well-being and QoL, is unknown RESULTS: Quantitative studies published between 2011 and 2020 that examined the impact of programmes with a significant peer support component on parental/carer well-being, QoL and/or distress were identified from four databases and were searched and yielded 3605 articles, with 13 articles meeting the inclusion criteria. The results suggested that peer support is effective for reducing distress and improving the well-being and QoL among parents of children with disabilities; however, the evidence is limited by a high risk of bias in the included studies.

CONCLUSIONS

Although existing evidence suggests that programmes for parents/carers with a significant peer support component are beneficial for well-being and QoL, rigorous methodologies are needed in the future to gain a better understanding of the benefits of such programmes.

Identifying and Shifting Disempowering Paradigms for Families of Children With Disability Through a System Informed Positive Psychology Approach

Despite the emergence of socio-ecological, strength-based, and capacity-building approaches, care for children with disability remains primarily grounded in a deficit-based perspective. Diagnoses and interventions primarily focus on what children and families cannot do, rather than what might be possible, often undermining the competence, mental health, and functioning of both the children and their families. We first critically examine typical approaches to disability care for families of young children, describe the importance of a systems-informed positive psychology (SIPP) approach to care, and identify the existence of two dominant paradigms, disability is a disadvantage and experts know best. Then, we present a case study investigating families’ experiences with these two paradigms and whether shifts to alternative perspectives could occur through participation in a SIPP-based program co-designed by professionals and families. Of program participants, nine parents and five early intervention professionals participated in two separate focus groups, and ten e-books were randomly selected for review. Thematic analysis of the e-books and focus group data identified two primary themes representing alternative perspectives that arose through the intervention: we will start with our strengths and we’ve got this. Participant comments indicated that they developed a greater sense of hope, empowerment, engagement, and wellbeing, enabled by embedding wellbeing concepts and practices in their routines and communications with their children. We suggest that benefits arose in part from the structure of the program and the development of wellbeing literacy in participants. While care needs to be taken in generalizing the results, the case study provides clear examples of shifts in perspectives that occurred and suggests that the incorporation of SIPP principles within early intervention approaches provides a potential pathway for shifting the problematic paradigms that dominate disability care.

“Power From Within” and Masculine Language: Does New Age Language Work at Work?

This study investigates the use, by women, of New Age spirituality (NAS) language in the workplace. Quantitative and qualitative data collected in New Zealand and Israel show that women reported using NAS language more than men, and that NAS language are generally silenced. Results show that if not calculated correctly, women’s use of NAS can lead to the loss of social capital and cultural capital in the workplace. In addition, women use NAS language as a set of ideas that shape the way they behave, as a form of “power from within,” and as “spiritual capital.” The article draws out some implications for theory on language and power in the workplace, by showing that silenced languages may remain alive within people, directing responses and actions, and for feminist research, by suggesting that women’s spirituality should be considered as a factor in explaining the interpretation and negotiation of workplace challenges, by women.

Identification of genomic deletions spanning the PCDH19 gene in two unrelated girls with intellectual disability and seizures

Recently, missense and truncating mutations in the gene PCDH19 have been reported to cause female-restricted epilepsy with mental retardation (EFMR). EFMR (MIM#300088) is an X-linked disorder characterized by early onset seizures and intellectual disability (ID). Interestingly, unlike typical X-linked mode of inheritance, the phenotype is restricted to females, and males are unaffected carriers. PCDH19 is highly expressed in brain, and the encoded protein belongs to the cadherin superfamily. Here we report two unrelated female patients with deletions spanning PCDH19 identified by copy number variation (CNV) analysis and validated by qPCR. In one, we have identified a 3 Mb interstitial deletion at Xq21.33-q22.1 which spans PCDH19, LOC442459 & TNMD. This patient had her first seizure at 8 months old, and also has ID and aggressive behavior. In another female patient we identified a de novo 603 kb heterozygous deletion in a female patient with fits (since 1 year of age), ID, hyperactivity and aggressive behavior. The deletion spans the entire PCDH19 gene (also TNMD, SRPX2, TSPAN6 and SYTL4). In conclusion, our results suggest that deletions at PCDH19 also cause EFMR.

Autoimmune polyglandular syndrome type 2 shows the same HLA class II pattern as type 1 diabetes

Autoimmune polyglandular syndrome (APS) type 2 is defined by the manifestation of at least two autoimmune endocrine diseases. Only few data exist on genetic associations of APS type 2. In this controlled study, 98 patients with APS type 2, 96 patients with type 1 diabetes (T1D), and 92 patients with autoimmune thyroid disease, both as a single autoimmune endocrinopathy, were tested for association with alleles of the human leukocyte antigen (HLA) class II loci DRB1, DQA1, and DQB1. Patients with APS type 2 had significantly more often the alleles DRB1*03 (P(c) < 0.0001), DRB1*04 (P(c) < 0.000005), DQA1*03 (P(c) < 0.0001), and DQB1*02 (P(c) < 0.05), when compared with controls. Less frequent in APS were DRB1*15 (P(c) < 0.05), DQA1*01 (P(c) < 0.0005), and DQB1*05 (P(c) < 0.005). With regard to frequency and linkage of these alleles, the susceptible haplotypes DRB1*0301-DQA1*0501-DQB1*0201 and DRB1*0401/04-DQA1*0301-DQB1*0302 were deduced. Protective haplotypes in this study were DRB1*1501-DQA1*0102-DQB1*0602 and DRB1*0101-DQA1*0101-DQB1*0501. Comparing APS patients with vs without AD, no significant differences regarding HLA class II alleles were noted in our collective. Patients with T1D as a singular disease had the same susceptible and protective HLA alleles and haplotypes. The prevalence of DRB1*03 and DRB1*04 in APS patients was not because of the presence of diabetes, as the APS type 2 patients without diabetes had the same allele distribution. In conclusion, these data suggest a common immunogenetic pathomechanism for T1D and APS type 2, which might be different from the immunogenetic pathomechanism of other autoimmune endocrine disease.

Extracting Leadership Knowledge from Formative Experiences

Leadership formative experiences (LFEs) are those experiences that make a high impact on leaders resulting in learning relevant to their leadership. This intervention was designed to capture LFEs through bi-focal lenses of leadership research (explore the process by which leaders build and share knowledge) and development (raise participants' awareness of self and others to shape effective leadership interventions). Senior leaders participating on a leadership development programme recounted LFEs in peer groups to surface their learning. Most LFEs occurred in adulthood (76%) identifying `self-improvement' (40%), `coping with struggle'(33%), `personal relationship/role model' (13%) and `parental/symbolic relationship' (5%) sensemaking categories. Only 8 per cent addressed a `natural process'supporting a `born leader' view and 1 per cent involved identification with a cause. Experiences powered `from within' in pursuit of self-development were more effective in extracting lessons from LFEs than where learning occurred through coping with adversity. The research details LFE impact located in the social construction process embedded in micro-interactions of leaders with those they help develop.

SmiNet-2: Description of an internet-based surveillance system for communicable diseases in Sweden

Electronic systems for communicable diseases surveillance enhance quality by simplifying reporting, improving completeness, and increasing timeliness. In this article we outline the ideas and technologies behind SmiNet-2, a new comprehensive regional/national system for communicable disease surveillance in Sweden. The system allows for reporting from physicians (web form) and laboratories (direct from lab data system) over the internet. Using a unique personal identification number, SmiNet-2 automatically merges clinical and laboratory notifications to case records. Privileged users, at national and county level, work against a common central server containing all notifications and case records. In addition, SmiNet-2 has separate county servers with tools for outbreak investigations, contact tracing and case management. SmiNet-2 was first used in September 2004. Individual counties receive up to 90% of all notifications electronically. In its first year, SmiNet-2 received 54 980 clinical notifications and 32 765 laboratory notifications, which generated 58 891 case records. Since most clinicians in Sweden have easy access to the internet, a general web-based reporting has been feasible, and it is anticipated that within a few years all reporting to SmiNet-2 will be over the internet. In this context, some of the major advantages of SmiNet-2 when compared with other systems are timeliness in the dataflow (up to national level), the full integration of clinical and laboratory notifications, and the capability to handle more than 50 diseases with tailor-made notification forms within one single system.

Prevalence of obesity in Sweden

Although the prevalence of obesity in Sweden still is low in an international perspective, the development during the last decades is alarming in adults, adolescents and children alike. The prevalence of obesity [body mass index (BMI) > 30 kg m-2] in adults has doubled during the last two decades and is now approximately 10% in both men and women, according to estimates based on self-reported BMI from repeated random samples of the population. However, prevalence estimates based on measured BMI from the WHO MONICA study indicate that the self-reported data result in underestimates. In military conscripts, the prevalence of obesity (BMI > 30 kg m-2) almost quadrupled to 3.2% from 1971 to 1995, while the overweight fraction (BMI > 25 kg m-2) more than doubled to 16.3%. The development in younger age groups seems to be similar; the prevalence of overweight [International Obesity Task Force (IOTF)/Cole] in children aged 10 years in Gothenburg has doubled to 18% (2.9% obese) during the last decade, and similar figures have been reported in other studies. However, most reports on childhood overweight stem from the larger metropolitan areas, and hence may be underestimates because of the urban-rural influence on obesity-status. Recent data from non-urban areas in the northern part of Sweden estimate the prevalence of overweight (BMI > 20 kg m-2) in 10-year-olds to above 30%. In the most comprehensive study in children, including both rural and urban areas, BMI was measured among all children aged 10 years (n = 5517; 92.7% of the population) in the county of Ostergotland, and the prevalence of overweight (IOTF/Cole) was 22% in both boys and girls, of which 4% and 5% were obese respectively.

Hexafluorine vs. Standard Decontamination to Reduce Systemic Toxicity After Dermal Exposure to Hydrofluoric Acid

INTRODUCTION

Dermal exposure to hydrofluoric acid (HF) may cause severe burns and systemic toxicity. Hexafluorine (Prevor, France) is a product marketed as an emergency decontamination fluid for HF skin and eye exposures. Documentation concerning Hexafluorine is scanty, and a recent study indicates that its ability to reduce HF burns is at most equal to that of water.

OBJECTIVE

The present study was conducted to evaluate Hexafluorine's capacity to reduce HF-induced systemic toxicity.

METHODS

Sprague Dawley rats were anesthetized, catheterized in the left femoral artery, and shaved on their back. A filter paper (3.5 x 6 cm) was soaked in 50% HF and applied on the back of each rat for 3 min. Thirty seconds after removal of the paper, a 3-min rinsing with either 500 mL Hexafluorine (group H), 500 mL water (group W), or 500 mL water followed by a single application of 2.5% calcium gluconate gel (group Ca) was carried out. Blood samples were analyzed for ionized calcium and potassium (before injury and 1, 2, 3, and 4 h after) and also for ionized fluoride (1, 2, and 4 h after injury).

RESULTS

The animals developed hypocalcemia, hyperkalemia, and hyperfluoridemia after the HF exposure. The only significant difference observed among the groups was in serum potassium at 1 h between group Ca and group W. However, there was a constant trend toward milder hypocalcemia and less pronounced hyperkalemia in group Ca compared to the other groups. There were no differences in the electrolyte disturbances between the Hexafluorine-treated animals and those treated with water only. Five of 39 animals died before completion of the experiment as a result of the HF exposure, one from group Ca and two from each of the other two groups.

CONCLUSION

In this experimental study, decontamination with Hexafluorine was not more effective than water rinsing in reducing electrolyte disturbances caused by dermal exposure to hydrofluoric acid.

Weak evidence of thyrotropin receptors in primary cultures of human osteoblast-like cells

Extra-thyroidal thyrotropin (TSH) receptors (TSHRs) have been demonstrated in several tissues and cells, including human and rat osteosarcoma cell lines. We have explored whether human TSHR (hTSHRs) also are present in primary cultures of human osteoblast-like (hOB) cells. [(125) I]TSH binding was limited in hOB cells, but somewhat higher in UMR 106-01 cells and considerably higher in hTSHR-transfected CHO cells. In hOB cells, the basal intracellular cAMP levels increased 282% after stimulation with 10 U/L TSH. In the hTSHR-transfected CHO cells, the cAMP increase was 3030% in response to 10 U/L TSH and 1240% after 1 U/L TSH. Free cytoplasmic calcium did not change in response to TSH in hOB cells. HTSHR mRNA was detected in hOB cells from 3/4 bone by reverse transcriptase polymerase chain reaction RT-PCR and nucleotide sequencing HTSHR mRNA, but could not be demonstrated with the RNase protection technique in hOB cells from 5 different donors. In conclusion, even after the use of several methods, we have found only weak evidence for expression and presence of functionally active hTSHR in hOB cells. Given the low level of expression, specific binding and cAMP signaling, we suggest that it is unlikely that circulating TSH plays a physiological role for bone metabolism mediated through osteoblasts.

High mobility group 1 protein (HMG-1) stimulates proinflammatory cytokine synthesis in human monocytes

Lipopolysaccharide (LPS) is lethal to animals because it activates cytokine release, causing septic shock and tissue injury. Early proinflammatory cytokines (e.g., tumor necrosis factor [TNF] and interleukin [IL]-1) released within the first few hours of endotoxemia stimulate mediator cascades that persist for days and can lead to death. High mobility group 1 protein (HMG-1), a ubiquitous DNA-binding protein, was recently identified as a "late" mediator of endotoxin lethality. Anti-HMG-1 antibodies neutralized the delayed increase in serum HMG-1, and protected against endotoxin lethality, even when passive immunization was delayed until after the early cytokine response. Here we examined whether HMG-1 might stimulate cytokine synthesis in human peripheral blood mononuclear cell cultures. Addition of purified recombinant HMG-1 to human monocyte cultures significantly stimulated the release of TNF, IL-1alpha, IL-1beta, IL-1RA, IL-6, IL-8, macrophage inflammatory protein (MIP)-1alpha, and MIP-1beta; but not IL-10 or IL-12. HMG-1 concentrations that activated monocytes were within the pathological range previously observed in endotoxemic animals, and in serum obtained from septic patients. HMG-1 failed to stimulate cytokine release in lymphocytes, indicating that cellular stimulation was specific. Cytokine release after HMG-1 stimulation was delayed and biphasic compared with LPS stimulation. Computer-assisted image analysis demonstrated that peak intensity of HMG-1-induced cellular TNF staining was comparable to that observed after maximal stimulation with LPS. Administration of HMG-1 to Balb/c mice significantly increased serum TNF levels in vivo. Together, these results indicate that, like other cytokine mediators of endotoxin lethality (e.g., TNF and IL-1), extracellular HMG-1 is a regulator of monocyte proinflammatory cytokine synthesis.

Presence of thyrotropin receptor in infant adipocytes

In healthy infants, the levels of TSH are known to peak at 50-100 times adult values during the first days of life. In studies of isolated human infant adipocytes, we have earlier shown that bovine TSH (bTSH) has a strong lipolytic effect, accompanied by a blunted response of adipocytes to catecholamines. In this study, we used human recombinant TSH (hTSH), and incubation of adipocytes with hTSH induced a lipolytic response similar to that obtained with the beta-adrenergic receptor agonist isoprenaline in adipocytes isolated from three infants. The lipolytic effect of hTSH was completely blocked by inhibitory TSH receptor (TSHR) antibodies. The TSHR mediates the effects of TSH in the thyroid, and it has been detected in some extrathyroid tissues, but not in isolated human adipocytes or childhood adipose tissue. In this study, we found TSHR RNA in infant and adult adipose tissues and isolated adipocytes with reverse transcriptase-PCR. The sequence of the amplified PCR product agreed with the published sequence. Northern blot hybridization on RNA prepared from infant adipose tissue showed a transcript of the expected size, and the expression of TSHR seemed higher in infant than in adult adipose tissue. In conclusion, this study indicates that TSH plays an active role in the metabolic adaptation after birth.

The lipolytic effects of thyrotropin and isoprenaline are not affected by growth hormone in infant adipocytes

The lipolytic effects of growth hormone (GH) in children are not fully clarified. In this study, no lipolytic effect of GH on isolated adipocytes obtained at surgery on healthy infants aged 2-5 months and children 3-6 years was observed. Furthermore, GH did not enhance isoprenaline-induced lipolysis, as in adults. The TSH-induced lipolysis which is prominent in neonatal adipocytes was not affected by incubation of adipocytes with GH. Assuming that GH alters adipocyte metabolism primarily by increasing the sensitivity, but not the maximum response, of the beta 2-adrenergic receptor population, it follows that GH, in this sense, should be a less important co-actor in children where beta 2-adrenergic receptors are more abundant.

Incidence of falls in three different types of geriatric care. A Swedish prospective study

The incidence and consequences of falls were investigated in three different types of Swedish geriatric care clinics: a geriatric rehabilitation clinic, a psychogeriatric clinic and a nursing home. Falls were prospectively registered by the nursing staff. The incidence rate (and 95% confidence interval) of falls per 10,000 patient days of the psychogeriatric clinic was 171 (146-196), compared with 92 (72-112) at the geriatric rehabilitation clinic, and 31 (22-41) at the nursing home. Most falls (62%) did not result in injury, while major injuries occurred in 5%. We conclude that accidental falls are a major problem in geriatric care in Sweden, but there is a considerable difference in incidence rates between different types of institutions.

Evidence for the presence of functional thyrotropin receptor in cardiac muscle

There is increasing evidence that the membrane-bound thyrotropin receptor (TSHR) may be mediating clinically important direct effects of thyrotropin (TSH) and of TSHR antibodies (TSHRab) in extra-thyroidal tissues. TSHR mRNA has formerly been detected in thyroid, retroorbital muscle and fibroblasts, peripheral lymphocytes and rodent fat. It is well known that thyroid disease may aggravate or induce heart disease, but the pathophysiological role of TSH and TSHRab is not clear. The aim of this study was to investigate if TSHR is present in cardiac muscle. Reverse transcriptase polymerase chain reactions revealed TSHR in human heart and Northern blot on extracted RNA showed a RNA species of 4.4 kb. TSH stimulation of cultured mouse AT-1 cardiomyocytes elevated the levels of intracellular second messenger 3',5'-cyclic AMP. This effect of TSH could be inhibited by TSHR antibodies. In solution hybridization levels of TSHR mRNA in AT-1 cells were 50% of mRNA in crude mouse heart. In conclusion functional TSHR is present in cardiomyocytes.

Effects of stimulatory and inhibitory thyrotropin receptor antibodies on lipolysis in infant adipocytes

TSH is a potent lipolytic hormone for isolated human adipocytes from neonatal subjects. Crude immunoglobulin fractions from sera of patients with Graves' disease, containing stimulatory TSH receptor (TSHR) autoantibodies, significantly increased lipolysis in fat cells from infants, whereas immunoglobulin fraction from a patient with inhibitory TSHR autoantibodies (TBab) blocked TSH-induced lipolysis in a dose-dependent manner. Although TBab totally blocked the maximum lipolysis induced by TSH (10(5) mU/L), no effect was seen on isoprenaline-induced lipolysis. The maximum lipolytic response to TSH was similar to that seen with the beta-adrenoceptor agonist isoprenaline, and there was a similar cAMP increase in response to both stimulators. From these results, it is concluded that the TSHR in infant adipocytes is likely to be coupled to the adenylate cyclase system, and the lipolytic effect of TSH can be simulated by stimulatory TSHR autoantibodies or inhibited by TBab.

Characterization of a Mycobacterium leprae antigen related to the secreted Mycobacterium tuberculosis protein MPT32

Secreted proteins may serve as major targets in the immune response to mycobacteria. To identify potentially secreted Mycobacterium leprae antigens, antisera specific for culture filtrate proteins of Mycobacterium tuberculosis were used to screen a panel of recombinant antigens selected previously by leprosy patient sera. Four potentially secreted antigens were identified by this approach, and one was recognized by antibodies specific for MPT32, a secreted M. tuberculosis protein. The DNA coding for the M. leprae antigen, which we have designated 43L, was isolated and characterized and found to encode a 25.5-kDa protein that is preceded by a consensus signal peptide of 39 amino acids. The N-terminal amino acid sequence of 43L shows 50% homology with the 20 known N-terminal amino acids of MPT32, and 47% homology was found with the N terminus of a 45/47-kDa antigen complex identified in Mycobacterium bovis BCG. These findings indicate that 43L represents an antigen related to MPT32 and the M. bovis BCG 45/47-kDa complex and that 43L is likely to be a protein secreted by M. leprae. Purified recombinant 43L protein is recognized by antibodies and T cells from healthy contacts and leprosy patients, illustrating that secreted proteins are of importance in the immune response to M. leprae.

Molecular mapping of interactions between a Mycobacterium leprae-specific T cell epitope, the restricting HLA-DR2 molecule, and two specific T cell receptors

A systematic series of 89 single residue substitution analogs of the Mycobacterium leprae 65-kDa protein-derived peptide LQAAPALDKL were tested for stimulation of two HLA-DR2 restricted 65 kDa-reactive T cell clones from a tuberculoid leprosy patient. Some analogs with substitutions outside a "core" region showed enhanced stimulation of the T cell clones. This core region of seven or eight residues was essential for recognition, whereas substitution of amino acids outside this region did not affect T cell recognition although these residues could not be omitted. Thus these core residues interact directly with the presenting HLA-DR2 molecule and/or the TCR. Except for analogs of position 419 for clone 2B6, the majority of the nonstimulatory substitution analogs did not inhibit the presentation of LQAAPALDKL and thus probably failed to bind to the HLA-DR2 molecule. Unless all of the core residues are physically involved in binding to DR2, substitution at a position not directly involved in binding appears to have an influence on other residues that do bind to the DR2 molecule. Active peptide analogs with two or more internal prolines suggest that not all analogs need be helical for activity with clone 2F10.
