Association of continuity of carer and women's experiences of maternity care during the COVID-19 pandemic: A cross-sectional survey.

BACKGROUND: Recent research highlights the impact of the COVID-19 pandemic on maternity services, although none to date have analysed the association between continuity of carer and how women felt about the changes to pregnancy care and birth plans. AIM: To describe pregnant women's self-reported changes to their planned pregnancy care and associations between continuity of carer and how women feel about changes to their planned care. METHODS: A cross-sectional online survey of pregnant women aged over 18 years in their final trimester of pregnancy in Australia. FINDINGS: 1668 women completed the survey. Most women reported at least one change to pregnancy care and birthing plans. Women receiving full continuity of carer were more likely to rate the changes to care as neutral/positive (p<.001) when compared with women who received partial or no continuity. DISCUSSION: Pregnant women experienced many changes to their planned pregnancy and birth care during the COVID-19 pandemic. Women who received full continuity of carer experienced fewer changes to care and were more likely to feel neutral/positive about the changes than women who did not receive full continuity of carer.

The effect of motivational interviewing and/or cognitive behaviour therapy techniques on gestational weight gain - a systematic review and meta-analysis.

BACKGROUND: Women with gestational weight gain (GWG) that is below or above recommendations are at risk of adverse perinatal outcomes. Motivational interviewing and/or cognitive behaviour therapy have demonstrated efficacy in initiating and sustaining behaviour change, including weight control. The objective of this review was to investigate the effect of antenatal interventions that include components of motivational interviewing and/or cognitive behaviour therapy on gestational weight gain. METHODS: This review was designed and reported in accordance with guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Five electronic databases were systematically searched to March 2022. Randomised controlled trials evaluating interventions with identified components of motivational interviewing and/or cognitive behaviour therapies were included. Pooled proportions of appropriate GWG and GWG above or below guidelines, and standardised mean difference for total gestational weight gain, were calculated. Risk of bias in included studies was evaluated using the Risk of Bias 2 tool, and the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence. RESULTS: Twenty-one studies (8030 participants) were included. Overall, MI and/or CBT interventions had a small effect on the total gestational weight gain (SMD: -0.18, 95% confidence interval: -0.27 to -0.09, p < 0.001) and improved the proportion of women achieving recommended gestational weight gain (29% versus 23% in the comparison, p < 0.001). The GRADE assessment indicated that overall quality of evidence is very uncertain, however sensitivity analyses to account for high risk of bias produced similar results to original meta-analyses. The magnitude of effect was greater in women with overweight or obesity when compared to women with BMI < 25 kg/m2. CONCLUSION: Motivational interviewing and/or cognitive behaviour therapy techniques may be effective for promoting healthy gestational weight gain. Nevertheless, a high proportion of women do not achieve recommended gestational weight gain. Future interventions should consider factors, including clinician and consumer perspectives, in the design and delivery of psychosocial interventions that aim to support healthy gestational weight gain. TRIAL REGISTRATION: The protocol for this review was registered with the PROSPERO International register of systematic reviews (registration number CRD42020156401).

Trends in percentages of gestational diabetes mellitus attributable to overweight, obesity, and morbid obesity in regional Victoria: an eight-year population-based panel study.

BACKGROUND: Gestational diabetes mellitus (GDM) is the fastest growing type of diabetes in Australia with rates trebling over the past decades partially explained by rising obesity rates and maternal age among childbearing women. Percentage of GDM attributable to obesity has been documented, mostly focusing on metropolitan populations. In parts of regional (areas outside capital cities) and rural Australia where overweight, obesity and morbid obesity are more prevalent, intertwined with socioeconomic disadvantage and higher migrant communities, trends over time in adjusted percentages of GDM attributed to obesity are unknown. METHODS: In this population-based retrospective panel study, women, without pre-existing diabetes, delivering singletons between 2010 and 2017 in a tertiary regional hospital that serves 26% of Victoria's 6.5 million Australian population were eligible for inclusion. Secular trends in GDM by body mass index (BMI) and age were evaluated. The percentage of GDM that would have been prevented each year with the elimination of overweight or obesity was estimated using risk-adjusted regression-based population attributable fractions (AFp). Trends in the AFp over time were tested using the augmented Dickey-Fuller test. RESULTS: Overall 7348 women, contributing to 10,028 births were included. The age of expecting mothers, their BMI, proportion of women born overseas, and GDM incidence significantly rose over time with GDM rising from 3.5% in 2010 to 13.7% in 2017, p <  0.001, increasing in all BMI categories. The incidence was consistently highest among women with obesity (13.8%) and morbid obesity (21.6%). However, the highest relative increase was among women with BMI < 25 kg/m2, rising from 1.4% in 2010 to 7.0% in 2017. Adjusting for age, country of birth, socioeconomic status, comorbidities, antenatal and intrapartum factors, an estimated 8.6% (confidence interval (CI) 6.1-11.0%), 15.6% (95% CI 12.2-19.0%), and 19.5% (95% CI 15.3-23.6%) of GDM would have been prevented by eliminating maternal overweight, obesity, and morbid obesity, respectively. However, despite the rise in obesity over time, percentages of GDM attributable to overweight, obesity, and morbid obesity significantly dropped over time. Scenario analyses supported these findings. CONCLUSIONS: Besides increasing prevalence of obesity over time, this study suggests that GDM risk factors, other than obesity, are also increasing over time.

Women, clinician and IT staff perspectives on telehealth for enhanced gestational diabetes mellitus management in an Australian rural/regional setting.

INTRODUCTION: Women in rural and regional areas encounter challenges when accessing care for gestational diabetes mellitus (GDM). A telehealth initiative for GDM care in an urban setting demonstrated positive effects on achieving glycaemic targets without compromising quality of care, but consumer and health service staff perspectives have not been explored. This research aimed to identify the profiles of women accessing care for GDM in a large regional hospital with a rural catchment in Victoria, Australia as well as gain insight into the views of the women with GDM, clinicians and IT staff on the acceptability and feasibility of a GDM telehealth in this setting. METHODS: Clinical and demographic characteristics of women accessing the GDM service between October 2016 and October 2017 were audited. Semi-structured interviews were completed with nine patients, three clinical staff and two IT service staff. Quantitative and qualitative data were analysed descriptively and thematically, respectively. RESULTS: Telehealth was viewed favourably by women and staff, with many perceived benefits identified around mitigating challenges of accessing care, and service capacity and provision. Concerns were raised around potential costs incurred by women and health services in accessing telehealth initiatives. Staff highlighted that moderation of workloads and coordination of telehealth services would be essential to the success of a future telehealth initiative. CONCLUSION: This article contributes important knowledge around GDM care in rural and regional settings and the perspectives of women with GDM, clinicians and technical support staff. Women and health services staff consider telehealth a feasible and acceptable alternative to current GDM care and address many of the barriers and impacts of attending care in person. Perceived benefits to patients and health services need to be balanced against the concerns around the work and costs to deliver GDM telehealth services.

Validation of triple pass 24-hour dietary recall in Ugandan children by simultaneous weighed food assessment.

BACKGROUND: Undernutrition remains highly prevalent in African children, highlighting the need for accurately assessing dietary intake. In order to do so, the assessment method must be validated in the target population. A triple pass 24 hour dietary recall with volumetric portion size estimation has been described but not previously validated in African children. This study aimed to establish the relative validity of 24-hour dietary recalls of daily food consumption in healthy African children living in Mbale and Soroti, eastern Uganda compared to simultaneous weighed food records. METHODS: Quantitative assessment of daily food consumption by weighed food records followed by two independent assessments using triple pass 24-hour dietary recall on the following day. In conjunction with household measures and standard food sizes, volumes of liquid, dry rice, or play dough were used to aid portion size estimation. Inter-assessor agreement, and agreement with weighed food records was conducted primarily by Bland-Altman analysis and secondly by intraclass correlation coefficients and quartile cross-classification. RESULTS: 19 healthy children aged 6 months to 12 years were included in the study. Bland-Altman analysis showed 24-hour recall only marginally under-estimated energy (mean difference of 149kJ or 2.8%; limits of agreement -1618 to 1321kJ), protein (2.9g or 9.4%; -12.6 to 6.7g), and iron (0.43mg or 8.3%; -3.1 to 2.3mg). Quartile cross-classification was correct in 79% of cases for energy intake, and 89% for both protein and iron. The intraclass correlation coefficient between the separate dietary recalls for energy was 0.801 (95% CI, 0.429-0.933), indicating acceptable inter-observer agreement. CONCLUSIONS: Dietary assessment using 24-hour dietary recall with volumetric portion size estimation resulted in similar and acceptable estimates of dietary intake compared with weighed food records and thus is considered a valid method for daily dietary intake assessment of children in communities with similar diets. The method will be utilised in a sub-study of a large randomised controlled trial addressing treatment in severe childhood anaemia. TRIAL REGISTRATION: This study was approved by the Mbale Research Ethics committee (Reference: 2013-050).

Emerging therapies for mitochondrial disorders.

Mitochondrial disorders are a diverse group of debilitating conditions resulting from nuclear and mitochondrial DNA mutations that affect multiple organs, often including the central and peripheral nervous system. Despite major advances in our understanding of the molecular mechanisms, effective treatments have not been forthcoming. For over five decades patients have been treated with different vitamins, co-factors and nutritional supplements, but with no proven benefit. There is therefore a clear need for a new approach. Several new strategies have been proposed acting at the molecular or cellular level. Whilst many show promise in vitro, the clinical potential of some is questionable. Here we critically appraise the most promising preclinical developments, placing the greatest emphasis on diseases caused by mitochondrial DNA mutations. With new animal and cellular models, longitudinal deep phenotyping in large patient cohorts, and growing interest from the pharmaceutical industry, the field is poised to make a breakthrough.

Respiratory chain deficiency in nonmitochondrial disease.

OBJECTIVE: In this study, we report 5 patients with heterogeneous phenotypes and biochemical evidence of respiratory chain (RC) deficiency; however, the molecular diagnosis is not mitochondrial disease. METHODS: The reported patients were identified from a cohort of 60 patients in whom RC enzyme deficiency suggested mitochondrial disease and underwent whole-exome sequencing. RESULTS: Five patients had disease-causing variants in nonmitochondrial disease genes ORAI1, CAPN3, COLQ, EXOSC8, and ANO10, which would have been missed on targeted next-generation panels or on MitoExome analysis. CONCLUSIONS: Our data demonstrate that RC abnormalities may be secondary to various cellular processes, including calcium metabolism, neuromuscular transmission, and abnormal messenger RNA degradation.

Exploring the 'follow-through experience': a statewide survey of midwifery students and academics conducted in Victoria, Australia.

OBJECTIVE: Follow-through experiences (which enable midwifery students to experience continuity of care with individual women through pregnancy, labour and birth and the postnatal period) are a component of midwifery education programmes in Australia and the United Kingdom. Current accreditation standards in Australia require midwifery students to have a total of 20 continuity of care experiences with an average of 20 hours per woman over the duration of their course. There has been limited research regarding students' and academics' experiences of follow-through experiences; and there has been debate regarding the appropriate number of follow-through experiences in midwifery curricula. This study aimed to explore the follow-through experience from the perspective of midwifery students and academics in Victoria, Australia. DESIGN: cross-sectional design using a web-based survey. SETTING: Victoria, Australia. PARTICIPANTS: Students (n=401) and academics (n=35) from all seven universities in Victoria that offer accredited midwifery programmes including the Bachelor of Midwifery, Bachelor of Nursing/Bachelor of Midwifery double degree, Postgraduate Diploma of Midwifery and Masters of Midwifery (entry to practice). FINDINGS: Students and academics were in agreement that continuity of care is important to women. They considered the follow-through experience to be a unique and valuable learning opportunity and agreed that follow-through experiences should be included in midwifery education programmes. However, students and academics raised major concerns about the impact of follow-through experiences on students' capacity to meet university course requirements (such as missing lectures/tutorials and clinical placements), and spending extensive periods of time on-call both within and outside the university semester. Students and academics also reported concerns about the impact of follow-through experiences on students' personal lives, including paid employment and family responsibilities (such as childcare or caring for family members). KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: In settings where continuity of care options for women are relatively limited, prescriptive requirements regarding the number and hours of follow-through experiences can present significant challenges for midwifery students. Midwifery regulatory bodies should consider these findings when developing or revising standards for midwifery education.

Accumulation of cortical hyperphosphorylated neurofilaments as a marker of neurodegeneration in multiple sclerosis.

BACKGROUND: Axonal loss and grey matter neuronal injury are pathological processes that contribute to disease progression in multiple sclerosis (MS). Axon damage has been associated with changes in the phosphorylation state of neurofilaments and the presence of axonal spheroids. Perikaryal accumulation of abnormally phosphorylated neurofilament proteins has been reported in some neurodegenerative diseases. OBJECTIVES: The objective of this article is to determine whether abnormally phosphorylated neurofilament accumulates in neuronal perikarya in demyelinated MS cortex. METHODS: We used an antibody to hyperphosphorylated neurofilament-H (SMI-34) to assess the level and distribution of this antigen in paraffin sections of cerebral cortex from cases of neuropathologically confirmed MS and controls. We also examined the relationship of neurofilament phosphorylation to cortical demyelination. RESULTS: The number of SMI-34-positive neuronal somata was significantly higher in the MS cortex than the control cortex. As a proportion of the total number of neurons present (i.e. taking account of neuronal loss), the proportion of SMI-34-positive neurons was also significantly higher in the demyelinated and non-demyelinated MS cortex than the control cortex. CONCLUSIONS: MS is associated with the widespread accumulation of hyperphosphorylated neurofilament protein in neuronal somata, with the most marked accumulation in regions of cortical demyelination. This aberrant localisation of hyperphosphorylated neurofilament protein may contribute to neuronal dysfunction and degeneration in MS patients.

Changes in expression of the antioxidant enzyme SOD3 occur upon differentiation of human bone marrow-derived mesenchymal stem cells in vitro.

The discovery that mesenchymal stem cells (MSCs) secrete SOD3 may help explain studies in which MSCs have direct antioxidant activities both in vivo and in vitro. SOD3 is an antioxidant enzyme that dismutes toxic free radicals produced during inflammatory processes. Therefore, MSC production and secretion of active and therapeutically significant levels of SOD3 would further support the use of MSCs as a cellular based antioxidant therapy. The aim of this study was therefore to investigate in vitro if MSC differentiation down the adipogenic, chondrogenic, and osteogenic lineages influences the expression of the antioxidant molecule SOD3. Human bone marrow MSCs and their differentiated progeny were cultured under standard conditions and both the SOD3 gene and protein expression examined. Following adipogenesis, cultures demonstrated that both SOD3 protein and gene expression are significantly increased, and conversely, following chondrogenesis SOD3 protein and gene expression is significantly decreased. Following osteogenesis there were no significant changes in SOD3 protein or gene expression. This in vitro study describes the initial characterization of SOD3 expression and secretion by differentiated MSCs. This should help guide further in vivo work establishing the therapeutic and antioxidative potential of MSC and their differentiated progeny.

Pressures to adhere to treatment ('leverage') in English mental healthcare.

BACKGROUND: Coercion has usually been equated with legal detention. Non-statutory pressures to adhere to treatment, 'leverage', have been identified as widespread in US public mental healthcare. It is not clear if this is so outside the USA. AIMS: To measure rates of different non-statutory pressures in distinct clinical populations in England, to test their associations with patient characteristics and compare them with US rates. METHOD: Data were collected by a structured interview conducted by independent researchers supplemented by data extraction from case notes. RESULTS: We recruited a sample of 417 participants from four differing clinical populations. Lifetime experience of leverage was reported in 35% of the sample, 63% in substance misusers, 33% and 30% in the psychosis samples and 15% in the non-psychosis sample. Leverage was associated with repeated hospitalisations, substance misuse diagnosis and lower insight as measured by the Insight and Treatment Attitudes Questionnaire. Housing leverage was the most frequent form (24%). Levels were markedly lower than those reported in the USA. CONCLUSIONS: Non-statutory pressure to adhere to treatment (leverage) is common in English mental healthcare but has received little clinical or research attention. Urgent attention is needed to understand its variation and place in community practice.

Diagnosis of longitudinally extensive transverse myelitis.

Longitudinally extensive transverse myelitis (LETM) is a neurological condition characterised by a contiguous inflammatory lesion of the spinal cord. LETM is often associated with the autoimmune central nervous system disease neuromyelitis optica (NMO) and rarely with multiple sclerosis. The discovery of the NMO-IgG antibody, provides a useful serological marker of LETM associated with the NMO disease spectrum (LETM and/or optic neuritis). Here, the authors report two cases of LETM, which differ in disease severity and NMO-IgG antibody serological status.

State Effects of Two Forms of Meditation on Prefrontal EEG Asymmetry in Previously Depressed Individuals.

We investigated state effects of two forms of meditation on electroencephalography prefrontal α-asymmetry, a global indicator of approach versus withdrawal motivation and related affective state. A clinical series of previously depressed individuals were guided to practice either mindfulness breathing meditation (N = 8) or a form of meditation directly aimed at cultivating positive affect, loving kindness or metta meditation (N = 7). Prefrontal asymmetry was assessed directly before and after the 15-min meditation period. Results showed changes in asymmetry towards stronger relative left prefrontal activation, i.e., stronger approach tendencies, regardless of condition. Further explorations of these findings suggested that responses were moderated by participants' tendencies to engage in ruminative brooding. Individuals high in brooding tended to respond to breathing meditation but not loving kindness meditation, while those low in brooding showed the opposite pattern. Comparisons with an additionally recruited "rest" group provided evidence suggesting that changes seen were not simply attributable to habituation. The results indicate that both forms of meditation practice can have beneficial state effects on prefrontal α-asymmetry and point towards differential indications for offering them in the treatment of previously depressed patients.

The effects of analytical and experiential rumination on autobiographical memory specificity in individuals with a history of major depression.

This study examined the relationship between analytical rumination and autobiographical memory specificity in participants with a history of depression. Participants completed the autobiographical memory test twice, once before and once after an 8 min manipulation designed to increase either an abstract/analytical or concrete/experiential mode of information processing. Results indicated a significant three-way time (pre, post) x manipulation (analytical, experiential) x depressive rumination (high, low) interaction. This interaction was the result of a significant decline in memory specificity from pre- to post-manipulation in individuals reporting high levels of rumination about symptoms when depressed who were allocated to the analytical condition. The findings of this study extend previous work, suggesting that low memory specificity in formerly depressed patients may be a function of state levels of analytical self-focus, with this cognitive style being more easily reinstated in the recovery phase in those who report a greater trait tendency to ruminate about symptoms when low in mood.
