RESUMO

Background: Fetal alcohol spectrum disorder (FASD) is a common developmental disability that requires lifelong and ongoing support but is often difficult to find due to the lack of trained professionals, funding, and support available. Technology could provide cost-effective, accessible, and effective support to those living with FASD and their caregivers. Objective: In this review, we aimed to explore the use of technology available for supporting people living with FASD and their caregivers. Methods: We conducted a scoping review to identify studies that included technology for people with FASD or their caregivers; focused on FASD; used an empirical study design; were published since 2005; and used technology for assessment, diagnosis, monitoring, or support for people with FASD. We searched MEDLINE, Web of Science, Scopus, Embase, APA PsycINFO, ACM Digital Library, JMIR Publications journals, the Cochrane Library, EBSCOhost, IEEE, study references, and gray literature to find studies. Searches were conducted in November 2022 and updated in January 2024. Two reviewers (CZC and HW) independently completed study selection and data extraction. Results: In total, 17 studies exploring technology available for people with FASD showed that technology could be effective at teaching skills, supporting caregivers, and helping people with FASD develop skills. Conclusions: Technology could provide support for people affected by FASD; however, currently there is limited technology available, and the potential benefits are largely unexplored.

RESUMO

AIMS: To examine the relationship between prenatal alcohol exposure (PAE) and children's behavioural and emotional development in a large generalizable sample of women and their children in Aotearoa New Zealand. METHODS: Using data from the Growing Up in New Zealand longitudinal cohort, we investigated the relationship between maternal PAE and behavioural and emotional development in 8-year-old children. We explored secondary outcomes including measures of language, executive function, academic achievement, and adaptive behaviour. RESULTS: We found no significant differences in the measures of behavioural and emotional development in children 8 years old based on alcohol consumption. No significant differences in behavioural and emotional development were found based on amount of PAE and when PAE occurred, despite controlling for a range of potential confounding factors, such as neighbourhood deprivation and maternal health measures. PAE was associated with significantly higher scores for parent-rated oral language indicating better oral language. In Maori mothers, PAE was significantly associated with an increased risk of higher scores on two of the Strengths and Difficulties Questionnaire subscales. CONCLUSIONS: We did not find an association between PAE and behavioural and emotional development in children aged 8 years. PAE and behavioural and emotional development are difficult to measure accurately, and the moderating variables between them are complex. Future analyses will require larger cohorts of mothers and their children using precise measures of PAE and outcomes to enable more precise estimates of association.

RESUMO

Extensive research suggests that COVID-19 infection can lead to persistent changes in taste and smell perception. These sensory changes have the potential to exert lasting impacts on dietary choices, nutrition, and body weight. This study aims to explore COVID-related shifts in dietary intake among New Zealand university students. We conducted a survey involving 340 university students who had experienced COVID-19 infection between 2022 and 2023. Participants reported any changes in eating behavior since before the pandemic and were asked to complete a 24-h food record. Participants' total daily energy intake, macronutrient intake, and composition were then compared with data collected from a similar cohort before the COVID-19 pandemic, spanning from 2017 to 2019. Dietary outcomes were compared using MANCOVA while controlling for individual age, gender, ethnicity, and BMI. Approximately 25% of participants reported experiencing sensory alterations with COVID-19, with those participants more likely to report changes in their experience of sweet tastes but not salty or fatty foods. Analyses of the pre- and post-COVID cohorts revealed that participants in the post-COVID group exhibited significantly higher consumption of protein and sodium. Understanding the long-term impact of COVID-19 infection may offer crucial insights into the role of chemosensory perception in dietary behavior.

RESUMO

OBJECTIVE: The study aimed to assess potential effects of vaping on individual taste and smell perception in a sample of young adult New Zealanders. DESIGN: This cross-sectional study measured taste and smell perception using intensity and hedonic ratings to two olfactory (i.e., vanillin, methional) and two gustatory stimuli (i.e., sucrose, monosodium glutamate), representing sweet and savoury flavours. Detection sensitivities to sucrose and vanillin were also assessed using a forced choice detection paradigm aligned with the signal detection framework. MANCOVAs were employed to compare sensory perception between groups based on vaping use frequency. Additional regression analyses were conducted to identify potential predictors of intensity and hedonic sensory ratings. SETTING: Participants were recruited from the University of Otago student population and surrounding neighbourhoods of Dunedin, New Zealand in 2023. PARTICIPANTS: The study included 213 university students (98 vapers and 115 non-vapers) RESULTS: We found a significant difference in hedonic ratings for vanillin, indicating a stronger preference among non-vapers. However, no other differences between the two groups were significant. Notably, the use of tobacco and mint flavours were emerged as significant predictors for hedonic responses to the savoury smell and sweet taste stimulus, respectively. No significant differences were observed between groups in the ability to detect weak stimuli. CONCLUSIONS: Our findings suggest that vape use, particularly with specific flavours, may be associated with alterations in hedonic responses to smells. This finding may have potential implications for how vaping affects on food preferences and dietary choices.

RESUMO

Pregnancy is a transformative phase marked by significant behavioral and physiological changes. Substantial changes in pregnancy-related hormones are thought to induce changes in chemosensory perception, as often observed in non-human animals. However, empirical behavioral research on pregnancy-related olfactory or gustatory changes has not yet reached a consensus. This PROSPERO pre-registered systematic review and meta-analysis evaluated published data of olfactory and gustatory changes in pregnant individuals, across the three pregnancy trimesters and postpartum period. Our comprehensive search strategy identified 20 relevant studies, for inclusion in the meta-analysis. The meta-analysis revealed that pregnant individuals, regardless of trimester, performed significantly poorer in terms of odour identification, however, no difference was detected between non-pregnant controls and women postpartum. Additionally, pregnant women in the second and third trimester rated olfactory stimuli to be more intense. A slight decline in odour pleasantness ratings was observed amongst those in the second trimester. No major difference was observed between pregnant and non-pregnant subjects in terms of gustatory functions, except the first trimester appeared to be associated with increased pleasantness for the sweet taste. Post-hoc meta-regression analyses revealed that pregnancy stage was a significant predictor for observed effect size for odour intensity ratings, but not for odour identification scores. These findings provide valuable insights into the interplay between pregnancy and chemosensory perception, highlighting systematic physiological changes due to pregnancy. Healthcare providers can also utilize the knowledge of sensory shifts to better support pregnant women in making appropriate dietary choices, managing sense-related discomfort, and leading to potential sensory interventions. Overall, this research enhances our comprehension of sensory shifts during pregnancy, benefiting maternal health and pregnancy-related care.

RESUMO

AIM: To explore the lived experiences of individuals with fetal alcohol spectrum disorder (FASD), their caregivers, and professionals working with individuals with FASD. METHOD: We conducted a scoping review using qualitative methods to explore what it is like to live with FASD from the perspective of those living with FASD, their caregivers, and stakeholders experienced in working with individuals with FASD. We searched electronic databases and grey literature for research published between 2005 and 2022. RESULTS: The 47 studies included in this scoping review show that FASD affects people's lives on a daily basis. Individuals with FASD are aware of their disability and its effects. Caregivers face daily challenges raising children with FASD and are often left unsupported by professionals. Professionals are unprepared and frustrated when supporting someone with FASD. INTERPRETATION: FASD affects individuals, caregivers, and families on a daily basis; and they require improved support and funding.

RESUMO

Background: Fetal Alcohol Spectrum Disorder (FASD) is a common neurodevelopmental disorder but may be underrecognized and misunderstood by people who provide health and social support services. The aim of the research is to understand the FASD knowledge, attitudes, and practices among people employed by the social and community sector in New Zealand. Methods: We conducted an online survey of people working in the New Zealand social and community sector (i.e., social workers, support workers). The survey focused on the following areas: awareness of FASD; knowledge and beliefs about FASD; the impact of FASD on professional practice; and training needs. Results: Most participants reported a basic understanding of FASD, however only 5% felt very well prepared to support someone with FASD. A large majority of participants believed that FASD diagnosis may be stigmatising for individuals or families. Conclusion: There is a need to improve training, professional development, and workplace support for social and community workers in New Zealand to support people with FASD.

RESUMO

BACKGROUND AND AIMS: Physiological changes that occur during pregnancy can have long-term impacts on metabolism and neurosensory responses to food, which can impact nutrition and health outcomes. The ENERGY cohort is a longitudinal study that aims to capitalizes on pregnancy as a natural model of metabolic reprogramming in order to understand the neurosensory mechanisms underpinning links between metabolism and dietary behaviour. The study objectives are to test for multi-sensory shifts during pregnancy, and the effect of sensory changes on dietary choices and bodyweights, and to identify neurosensory mechanisms that determine macronutrient selection before and after pregnancy. METHODS: A longitudinal cohort study involving 130 pregravid women planning to conceive with the next 12-months and 65 pregravid women with no short-term plans to conceive. Participants will be recruited from Dunedin and Auckland, New Zealand. The study will test for changes in diet, neurosensory outcomes, and metabolism across the reproductive cycle, from pre-pregnancy to 1-year post-pregnancy. Data will be collected at six timepoint throughout the pregnancy which will occur approximately every 3 months. The primary response variables will be changes in supra-threshold sensitivity across modalities, dietary intake, and metabolism between pre-pregnancy and post-pregnancy. Longitudinal data analysis will use linear mixed models to assess changes in the response outcomes over time adjusted for age, ethnicity, and socioeconomic status. DISCUSSION: Understanding the relationship between metabolism, sensory processing, and macronutrient preferences will provide crucial insights into diet-related health issues, including obesity. This study will lead to the formation of a prospective research cohort that is unique to Aotearoa New Zealand, and will develop multidisciplinary skills that are increasingly necessary to addressing the obesity epidemic.

RESUMO

In response to tissue injury, within seconds the ultra-large glycoprotein von Willebrand factor (VWF) is released from endothelial storage organelles (Weibel-Palade bodies) into the lumen of the blood vasculature, where it leads to the recruitment of platelets. The marked size of VWF multimers represents an unprecedented burden on the secretory machinery of endothelial cells (ECs). ECs have evolved mechanisms to overcome this, most notably an actomyosin ring that forms, contracts, and squeezes out its unwieldy cargo. Inhibiting the formation or function of these structures represents a novel therapeutic target for thrombotic pathologies, although characterizing proteins associated with such a dynamic process has been challenging. We have combined APEX2 proximity labeling with an innovative dual loss-of-function screen to identify proteins associated with actomyosin ring function. We show that p21 activated kinase 2 (PAK2) recruits septin hetero-oligomers, a molecular interaction that forms a ring around exocytic sites. This cascade of events controls actomyosin ring function, aiding efficient exocytic release. Genetic or pharmacological inhibition of PAK2 or septins led to inefficient release of VWF and a failure to form platelet-catching strings. This new molecular mechanism offers additional therapeutic targets for the control of thrombotic disease and is highly relevant to other secretory systems that employ exocytic actomyosin machinery.

RESUMO

Background:Fetal alcohol spectrum disorder (FASD) is a common form of developmental disability but may be poorly understood by professionals working with people with FASD. The aim of the research is to understand the FASD knowledge, attitudes, awareness, and practices among people employed by the education sector in Aotearoa New Zealand and identify gaps in knowledge. Methods: We conducted an online survey of New Zealand Education professionals. The survey focused on the following areas: Awareness of FASD; Knowledge and beliefs about FASD; Impact of FASD on professional practice; and Training needs. Results: Of the 419 participants, most had some knowledge of FASD and its effects on learning; however, there are still gaps that need to be addressed so educators can provide support to individuals living with FASD. Conclusion: There is a need to improve workforce capacity and develop guidelines that address the needs of front-of-line staff working with children with FASD in education settings.

RESUMO

BACKGROUND AND AIMS: Fetal alcohol spectrum disorder (FASD) is one of the most common forms of developmental disability, and yet, anecdotally, is poorly understood by both the public and professionals across health, justice, education, and social services. This review aims to understand the knowledge, attitudes, and practices of professionals who work across a range of sectors - specifically health, education and justice - where they may encounter people with FASD, their families and caregivers. METHOD: We conducted a systematic search for research using surveys or questionnaires to address knowledge, and attitudes of professionals in health, education, and justice with regards to FASD between 1990 and 2021. Our search consisted of electronic databases (APA PsychInfo, CINAHL, EMBASE, Medline, PubMed, and PAIS Index) and grey literature sources. RESULTS: Our search yielded 971 results, of which 58 were relevant. The studies surveyed professionals from health (n = 35), education (n = 10), justice (n = 8), social services (n = 1), and multiple settings (n = 4). Most studies were conducted in North America. The areas surveyed included knowledge of FASD, attitudes towards people with FASD, experience with FASD, practices towards people with FASD, and education and training needs. CONCLUSIONS: Knowledge, attitudes, and practices towards FASD have been surveyed extensively in healthcare professionals over the last 30 years, but less so with those working in justice and education sectors. Findings from surveys suggest that although most professionals had some knowledge of the effects of FASD, their knowledge of the specific criteria of Fetal Alcohol Syndrome (FAS) and FASD is poor across most professional groups, including most health professionals. Our review highlights the need to provide training and information across sectors ongoing surveillance to determine where gaps in knowledge are and what resources are needed. WHAT THIS PAPER ADDS: This study is the first to systematically synthesize knowledge, attitudes, and practices toward FASD across different sectors. Poor knowledge and insufficient training were common. Knowledge, attitudes, and practices about FASD have been surveyed extensively in the healthcare setting, but surveys are more limited outside of this setting. Continuous surveillance is needed to identify and respond to knowledge gaps and changes in practice.

RESUMO

Background: Prenatal exposure to alcohol (PAE) represents a significant public health concern. Previous research linking PAE to neurodevelopmental outcomes has been mixed and often has limited focus on residual confounding or moderating factors. Methods: A systematic review of prospective cohort studies (n = >1000) assessing the impact of PAE on neurodevelopmental outcomes was undertaken (neurophysiology, motor skills, cognition, language, academic achievement, memory, attention, executive function, affect regulation, and adaptive behaviour, social skills, or communication). Electronic searches of EMBASE, Medline, CINAHL, and Psychinfo were conducted in May 2021. A quality assessment was conducted using an adapted version of the Newcastle-Ottawa Scale (NOS). Results: Thirty longitudinal cohort studies met the inclusion criteria. Evidence of the impact of PAE was mixed across domains. We found no evidence that PAE affects executive function, but there were impacts on motor skills, cognition, language, academic achievement, attention, affect regulation, and adaptive behaviour. The most consistent adverse effect was on affect regulation (nine out of thirteen studies, six of which found an association between heavy alcohol consumption or binge drinking during pregnancy). We found no protective factors. Few studies controlled for variables in the postnatal environment. Discussion: This review was unable to conclude a safe level of alcohol consumption during pregnancy. Methodological improvements are needed to improve the quality and consistency in which PAE is studied. Further research into residual confounding variables is vital, including a greater focus on the postpartum environment.

RESUMO

AIMS: To summarise the literature underpinning key recommendations made in the 2021 revision of the Ministry of Health's New Zealand Guidelines for Helping People to Stop Smoking. METHODS: A comprehensive literature review of smoking cessation interventions was undertaken in July 2021. Recommendations were formulated from the findings of the literature review and expert advice. RESULTS: Healthcare professionals should ask and briefly advise all people who smoke to stop smoking, regardless of whether they say they are ready to stop smoking or not. They should offer smoking cessation support, which includes both behavioural and pharmacological (e.g., nicotine replacement therapy, nortriptyline, bupropion or varenicline) interventions. The Guidelines also include advice around the use of vaping in smoking cessation. Recommendations are also formulated for priority populations of smokers: Maori, Pacific, pregnant women, and people with mental illness and other addictions. CONCLUSIONS: The guidelines will assist healthcare professionals in providing evidence-based smoking cessation support to people who smoke. To be effective and equitable, the ABC model requires organisational commitment, integration into routine practice, and increased attention to the upstream determinants of smoking and quitting.

RESUMO

BACKGROUND: In vertebrate cells, the Golgi functional subunits, mini-stacks, are linked into a tri-dimensional network. How this "ribbon" architecture relates to Golgi functions remains unclear. Are all connections between mini-stacks equal? Is the local structure of the ribbon of functional importance? These are difficult questions to address, without a quantifiable readout of the output of ribbon-embedded mini-stacks. Endothelial cells produce secretory granules, the Weibel-Palade bodies (WPB), whose von Willebrand Factor (VWF) cargo is central to hemostasis. The Golgi apparatus controls WPB size at both mini-stack and ribbon levels. Mini-stack dimensions delimit the size of VWF "boluses" whilst the ribbon architecture allows their linear co-packaging, thereby generating WPBs of different lengths. This Golgi/WPB size relationship suits mathematical analysis. RESULTS: WPB lengths were quantized as multiples of the bolus size and mathematical modeling simulated the effects of different Golgi ribbon organizations on WPB size, to be compared with the ground truth of experimental data. An initial simple model, with the Golgi as a single long ribbon composed of linearly interlinked mini-stacks, was refined to a collection of mini-ribbons and then to a mixture of mini-stack dimers plus long ribbon segments. Complementing these models with cell culture experiments led to novel findings. Firstly, one-bolus sized WPBs are secreted faster than larger secretory granules. Secondly, microtubule depolymerization unlinks the Golgi into equal proportions of mini-stack monomers and dimers. Kinetics of binding/unbinding of mini-stack monomers underpinning the presence of stable dimers was then simulated. Assuming that stable mini-stack dimers and monomers persist within the ribbon resulted in a final model that predicts a "breathing" arrangement of the Golgi, where monomer and dimer mini-stacks within longer structures undergo continuous linking/unlinking, consistent with experimentally observed WPB size distributions. CONCLUSIONS: Hypothetical Golgi organizations were validated against a quantifiable secretory output. The best-fitting Golgi model, accounting for stable mini-stack dimers, is consistent with a highly dynamic ribbon structure, capable of rapid rearrangement. Our modeling exercise therefore predicts that at the fine-grained level the Golgi ribbon is more complex than generally thought. Future experiments will confirm whether such a ribbon organization is endothelial-specific or a general feature of vertebrate cells.

RESUMO

Tentative results from feasibility analyses are critical for planning future randomized control trials (RCTs) in the emerging field of neural biomarkers of behavioral interventions. The current feasibility study used MRI-derived diffusion imaging data to investigate whether it would be possible to identify neural biomarkers of a behavioral intervention among people diagnosed with autism spectrum disorder (ASD). The corpus callosum has been linked to cognitive processing and callosal abnormalities have been previously found in people diagnosed with ASD. We used a case-control design to evaluate the association between the type of intervention people diagnosed with ASD had previously received and their current white matter integrity in the corpus callosum. Twenty-six children and adolescents with ASD, with and without a history of parent-managed behavioral intervention, underwent an MRI scan with a diffusion data acquisition sequence. We conducted tract-based spatial statistics and a region of interest analysis. The fractional anisotropy values (believed to indicate white matter integrity) in the posterior corpus callosum was significantly different across cases (exposed to parent-managed behavioral intervention) and controls (not exposed to parent-managed behavioral intervention). The effect was modulated by the intensity of the behavioral intervention according to a dose-response relationship. The current feasibility case-control study provides the basis for estimating the statistical power required for future RCTs in this field. In addition, the study demonstrated the effectiveness of purposely-developed motion control protocols and helped to identify regions of interest candidates. Potential clinical applications of diffusion tensor imaging in the evaluation of treatment outcomes in ASD are discussed.

RESUMO

Nonhuman animal models show that reinforcers control behavior through what they signal about the likelihood of future events, but such control is generally imperfect. Imperfect control by the relation between past and likely future events may result from imperfect detection of those events as they occur, which result in imperfect detection of the relation between events. Such an approach would suggest the involvement of more complex psychological processes like memory in simple operant learning. We extended a research paradigm previously examined with nonhuman animals to test the ability of a quantitative model that assumes imperfect control by the relation between events arises because of (a) occasional misallocation of reinforcers to the wrong response, causing imperfect control by the relation between events; and (b) a tendency to explore or exploit which is independent of the relation between events. Children played a game in which one of two different responses could produce a reinforcer. The likelihood of a reinforcer for the same response that produced the last one varied across three conditions (.1, .5, .9). As with nonhuman animal models, children's choices followed these probabilities closely but not perfectly, suggesting strong control by what one reinforcer signals about subsequent reinforcers. Choice was well described by the quantitative model. This same model also provides a good description of nonhuman animal-model data, suggesting fundamentally similar mechanisms of control across species. These findings suggest reinforcers control behavior to the extent the relation between reinforcers can be detected-that is, simple operant learning may be more complex than is typically assumed.

RESUMO

Background: The extent to which behavior-analytic interventions are offered to Indigenous populations across CANZUS in accessible and culturally appropriate ways is unknown. We conducted a scoping review with a thematic analysis of the extant literature to find: (1) what are the barriers and facilitators for providing effective and equitable delivery of psychological services (with a behavioral component) to Indigenous populations; and (2) what tools and practices exist for an effective and equitable service delivery. Methods: We systematically reviewed Medline, CINAHL, PubMed, PsycInfo, Web of science, Ovid and INNZ databases between 1990 and 2020. For the scoping review, we adhered to the JBI methodological approach (2015) and the PRISMA strategy for the identification, selection, and appraisal of the reviewed articles. A total of 1265 unique articles met the criteria for the screening by title; 238 by abstract; 57 were included for full text assessment; and 37 were included in the final analysis. Results: Three themes were revealed to account for the barriers and facilitators of culturally friendly practices: (1) connecting practices are about interactions shaping the relationship between service provider and service client; (2) innovative practices test new approaches and innovations that could facilitate access to psychological services and overcome barriers, and (3) reflective practices are about critically examining the processes and actions undertaken toward effective cultural adaptation of services. Conclusions: Our analysis suggests that the level of success in bringing together services and the recipients of treatment (connection), showing flexibility and persistence in finding solutions (innovation) and examining the role of our behaviors in reaching our goals (reflection) is determined by the providers' action in the aforementioned three dimensions of practice.

RESUMO

We sought to gain insights into the impacts of COVID-19 and associated control measures on health and health care of patients from low- and middle-income countries with cardiovascular disease, diabetes, and mental health conditions, using an online survey during the COVID-19 pandemic. The most common concern for the 1487 patients who took part was contracting COVID-19 when they accessed health care. Of those infected with COVID-19, half said that their health had been worse since being infected. Collectively, most people reported an increase in feelings of stress and loneliness. The COVID-19 pandemic has led to a range of health care impacts on patients with noncommunicable diseases, including constraints on access to care and health effects, particularly mental well-being.

RESUMO

BACKGROUND: The global COVID-19 pandemic has disrupted healthcare worldwide. In low- and middle-income countries (LMICs), where people may have limited access to affordable quality care, the COVID-19 pandemic has the potential to have a particularly adverse impact on the health and healthcare of individuals with noncommunicable diseases (NCDs). A World Health Organization survey found that disruption of delivery of healthcare for NCDs was more significant in LMICs than in high-income countries. However, the study did not elicit insights into the day-to-day impacts of COVID-19 on healthcare by front-line healthcare workers (FLHCWs). AIM: To gain insights directly from FLHCWs working in countries with a high NCD burden, and thereby identify opportunities to improve the provision of healthcare during the current pandemic and in future healthcare emergencies. METHODS: We recruited selected frontline healthcare workers (general practitioners, pharmacists, and other medical specialists) from nine countries to complete an online survey (n = 1347). Survey questions focused on the impact of COVID-19 pandemic on clinical practice and NCDs; barriers to clinical care during the pandemic; and innovative responses to the many challenges presented by the pandemic. FINDINGS: The majority of FLHCWs responding to our survey reported that their care of patients had been impacted both adversely and positively by the public health measures imposed. Most FLHCs (95%) reported a deterioration in the mental health of their patients.
