RESUMO

Asthma during pregnancy is associated with a range of adverse perinatal outcomes. It is also linked to increased rates of neurodevelopmental conditions in the offspring. We aimed to assess whether fractional exhaled nitric oxide (FENO)-based asthma management during pregnancy improves child developmental and behavioural outcomes compared to usual care. The Breathing for Life Trial was a randomised controlled trial that compared FENO-based asthma management during pregnancy to usual care. Participants were invited to the developmental follow-up, the Breathing for Life Trial - Infant Development study, which followed up infants at 6 weeks, 6 months and 12 months. The primary outcomes were measured in infants at 12 months using the Bayley-III: Cognitive, Language and Motor composite scores. Secondary outcomes included Bayley-III social-emotional and adaptive behaviour scores, autism likelihood and sensory and temperament outcomes. The exposure of interest was the randomised intervention group. Two hundred and twenty-two infants and their 217 participating mothers were recruited to the follow-up; 107 mothers were in the intervention group and 113 were in the control group. There was no evidence of an intervention effect for the primary outcomes: Bayley-III cognitive (mean = 108.9 control, 108.5 intervention, p = 0.93), language (mean = 95.9 control, 95.6 intervention, p = 0.87) and motor composite scores (mean = 97.2 control, 97.9 intervention, p = 0.25). Mean scores for secondary outcomes were also similar among infants born to control and FENO group mothers, with few results reaching p < 0.05. CONCLUSION:  In this sample, FENO-guided asthma treatment during pregnancy did not improve infant developmental outcomes in the first year of life. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: ACTRN12613000202763. WHAT IS KNOWN: • Maternal asthma during pregnancy has been associated with increased rates of neurodevelopmental conditions in offspring, including intellectual disability and autism. WHAT IS NEW: • This is the first study to examine how managing asthma during pregnancy via a FENO-guided algorithm or usual care affects infant developmental and behavioural outcomes. While the results of the study showed no impact of the intervention, and therefore do not support the integration of FENO-based management of asthma in antenatal settings for optimal infant development, they do send a positive message about the implications of active asthma management during pregnancy on infant developmental outcomes.

RESUMO

The Nile perch (Lates niloticus L.) commercial fishery for Lake Victoria in East Africa is an important source of revenue and employment. We focused on shifts in food web structure and total mercury (THg) bioaccumulation and biomagnification in Nile perch, and lower food web items collected from Winam Gulf (Kenya) sampled 24 years apart (1998 and 2022). Stable isotope carbon (δ13C) values were higher in all species from 2022 compared to 1998. Stable nitrogen isotope (δ15N) values in baseline organisms were lower in 2022 compared to 1998. In Nile perch, δ15N values were correlated with total length, but the δ15N-length regressions were steeper in 1998 compared to 2022 except for one large (158 cm) Nile perch from 1998 with an uncharacteristically low δ15N value. Total Hg concentrations were lower in lower trophic species from 2022 compared to 1998. However, the THg bioaccumulation rate (as a function of fish length) in Nile perch was greater in 2022 compared to 1998 resulting in 24.2 % to 42.4 % higher wet weight dorsal THg concentrations in 2022 Nile perch for market slot size (50 to 85 cm) fish. The contrasting observations of increased THg bioaccumulation with size in 2022 against decreases in the rate of trophic increase with size and lower THg concentrations of lower food web items imply reduced fish growth and potential bioenergetic stressors on Winam Gulf Nile perch. All samples except 1 large Nile perch (139 cm total length collected in 2022) had THg concentrations below the European Union trade limit (500 ng/g wet weight). However, for more vulnerable individuals (women, children and frequent fish eaters), we recommend a decrease in maximum monthly meal consumption for 55-75 cm Nile perch from 16 meals per month calculated for 1998 to a limit of 8 meals per month calculated for 2022.

RESUMO

22q11.2 deletion syndrome (22q11DS) is the most frequently occurring microdeletion in humans. It is associated with a significant impact on brain structure, including prominent reductions in gray matter volume (GMV), and neuropsychiatric manifestations, including cognitive impairment and psychosis. It is unclear whether GMV alterations in 22q11DS occur according to distinct structural patterns. Then, 783 participants (470 with 22q11DS: 51% females, mean age [SD] 18.2 [9.2]; and 313 typically developing [TD] controls: 46% females, mean age 18.0 [8.6]) from 13 datasets were included in the present study. We segmented structural T1-weighted brain MRI scans and extracted GMV images, which were then utilized in a novel source-based morphometry (SBM) pipeline (SS-Detect) to generate structural brain patterns (SBPs) that capture co-varying GMV. We investigated the impact of the 22q11.2 deletion, deletion size, intelligence quotient, and psychosis on the SBPs. Seventeen GMV-SBPs were derived, which provided spatial patterns of GMV covariance associated with a quantitative metric (i.e., loading score) for analysis. Patterns of topographically widespread differences in GMV covariance, including the cerebellum, discriminated individuals with 22q11DS from healthy controls. The spatial extents of the SBPs that revealed disparities between individuals with 22q11DS and controls were consistent with the findings of the univariate voxel-based morphometry analysis. Larger deletion size was associated with significantly lower GMV in frontal and occipital SBPs; however, history of psychosis did not show a strong relationship with these covariance patterns. 22q11DS is associated with distinct structural abnormalities captured by topographical GMV covariance patterns that include the cerebellum. Findings indicate that structural anomalies in 22q11DS manifest in a nonrandom manner and in distinct covarying anatomical patterns, rather than a diffuse global process. These SBP abnormalities converge with previously reported cortical surface area abnormalities, suggesting disturbances of early neurodevelopment as the most likely underlying mechanism.

RESUMO

PURPOSE: Mother-infant interactions during the first year of life are crucial to healthy infant development. The infant-directed speech (IDS), and specifically pitch contours, used by mothers during interactions are associated with infant language and social development. However, little research has examined pitch contours towards infants with socio-communication and language differences, such as those displaying early signs of autism spectrum disorder (autism). This study aimed to explore the association of infant autism signs and pitch contours used by mothers with their 12-month-old infants. METHOD: Mother-infant dyads (n = 109) were recruited from the University of Newcastle BabyLab. Parent-infant dyads completed a 15-min interaction, from which a total of 36,128 pitch contours were measured and correlated with infant autism signs. Infant autism signs were assessed via parent-report (First Year Inventory; Reznick et al., 2007). A subset of high-risk infants (admitted to a neonatal intensive care unit, n = 29) also received an observation-based assessment (Autism Detection in Early Childhood; Young & Nah, 2016). RESULTS: Mothers used fewer sinusoidal contours when they rated their infant as displaying more autism signs (rs = - .30, p = .004) and more autism-related sensory regulation issues (rs = - .31, p = .001). Mothers used fewer flat contours if their infant displayed more researcher-rated autism signs (r2 = - .39, p = .04). CONCLUSIONS: This study provides the early evidence that maternal pitch contours in IDS are related to early autism signs in infancy. If our findings are replicated in follow up studies where infants are followed to diagnosis, maternal IDS may be an important element of future early intervention protocols that focus on communication for infants with risk for autism.

RESUMO

Coparenting competence (CC) is a concept that describes the sense of collective efficacy that parents experience in raising children. An advantage of CC is that it bridges a gap between family systems thinking and efficacy theory, where extant research and theory have focused on the self-efficacy of one or both parents. This study aimed to develop a self-reported measure of CC. METHODOLOGY: Participants (n = 302), including cohabiting mothers (n = 240) and fathers (n = 62), completed an online survey (112 items) comprising demographic questions, the Coparenting Relationship Scale (CRS), the Parenting Sense of Competence Scale (PSOC), the Strengths and Difficulties Questionnaire (SDQ), and 36 items designed to explore perceptions of CC. RESULTS: Factor analyses on 36-CC items identified 10 items that reliably formed a brief Coparenting Competence Scale (CCS; Alpha = 0.89). Analysis of convergent and divergent validity demonstrated that the CCS measures a unique construct that is linked to parenting self-efficacy, measured by PSOC (r = 0.47), and coparenting quality, assessed by the CRS (r = 0.63). There was a significant association between CCS and SDQ across age groups and an association stronger than that found for the CRS and SDQ in the current cohort. CONCLUSIONS AND IMPLICATIONS: The study found support for the reliability and validity of the CCS. Coparenting competence, assessed by the CCS, was found to be distinct from factors previously used to represent coparenting quality in multivariate scales. The strength of associations between the CCS and SDQ suggests this new measure may have an important role in coparenting research.

RESUMO

Congenital heart disease (CHD) affecting the conotruncal region of the heart, occurs in 40-50% of patients with 22q11.2 deletion syndrome (22q11.2DS). This syndrome is a rare disorder with relative genetic homogeneity that can facilitate identification of genetic modifiers. Haploinsufficiency of TBX1, encoding a T-box transcription factor, is one of the main genes responsible for the etiology of the syndrome. We suggest that genetic modifiers of conotruncal defects in patients with 22q11.2DS may be in the TBX1 gene network. To identify genetic modifiers, we analyzed rare, predicted damaging variants in whole genome sequence of 456 cases with conotruncal defects and 537 controls, with 22q11.2DS. We then performed gene set approaches and identified chromatin regulatory genes as modifiers. Chromatin genes with recurrent damaging variants include EP400, KAT6A, KMT2C, KMT2D, NSD1, CHD7 and PHF21A. In total, we identified 37 chromatin regulatory genes, that may increase risk for conotruncal heart defects in 8.5% of 22q11.2DS cases. Many of these genes were identified as risk factors for sporadic CHD in the general population. These genes are co-expressed in cardiac progenitor cells with TBX1, suggesting that they may be in the same genetic network. The genes KAT6A, KMT2C, CHD7 and EZH2, have been previously shown to genetically interact with TBX1 in mouse models. Our findings indicate that disturbance of chromatin regulatory genes impact the TBX1 gene network serving as genetic modifiers of 22q11.2DS and sporadic CHD, suggesting that there are some shared mechanisms involving the TBX1 gene network in the etiology of CHD.

RESUMO

OBJECTIVE: Optimising antibiotic use is important to limit increasing antibiotic resistance. In rural Burkina Faso, over-the-counter dispensing of antibiotics in community pharmacies and non-licensed medicine retail outlets facilitates self-medication. We investigated its extent, reasons and dispensing patterns. METHODS: In an exploratory mixed-method design conducted between October 2020 and December 2021, this study first explored illness perceptions, the range of healthcare providers in communities, antibiotics knowledge and reasons for seeking healthcare outside healthcare facilities. Second, frequencies of illness and healthcare utilisation in the last 3 months were quantitatively measured. RESULTS: Participants distinguished between natural and magico-religious illnesses, according to origins. For illnesses considered to be 'natural', healthcare was mainly sought at healthcare facilities, private pharmacies and informal drug outlets. For illnesses considered as magico-religious, traditional healers were mainly visited. Antibiotics were perceived in the community as medicines similar to painkillers. Healthcare-seeking outside healthcare facilities was reported by 660/1973 (33.5%) participants reporting symptoms, including 315 (47.7%) to informal vendors. Healthcare seeking outside facilities was less common for 0-4-year-olds (58/534, 10.9% vs. 379/850, 44.1% for ≥5-year-olds) and decreased with improving socio-economic status (108/237, 45.6% in the lowest quintile; 96/418, 23.0% in the highest). Reported reasons included financial limitation, and also proximity to informal drug vendors, long waiting times at healthcare facilities, and health professionals' non-empathetic attitudes towards their patients. CONCLUSION: This study highlights the need to facilitate and promote access to healthcare facilities through universal health insurance and patient-centred care including reducing patients' waiting time. Furthermore, community-level antibiotic stewardship programmes should include community pharmacies and informal vendors.

RESUMO

Intimate partner violence (IPV) causes substantial physical and psychological trauma. Restrictions introduced in response to the COVID-19 pandemic, including lockdowns and movement restrictions, may exacerbate IPV risk and reduce access to IPV support services. This cross-sectional study examines IPV during COVID-19 restrictions in 30 countries from the International Sexual HeAlth and REproductive Health (I-SHARE) study conducted from July 20th, 2020, to February, 15th, 2021. IPV was a primary outcome measure adapted from a World Health Organization multicountry survey. Mixed-effects modeling was used to determine IPV correlates among participants stratified by cohabitation status. The sample included 23,067 participants from 30 countries. A total of 1,070/15,336 (7.0%) participants stated that they experienced IPV during COVID-19 restrictions. A total of 1,486/15,336 (9.2%) participants stated that they had experienced either physical or sexual partner violence before the restrictions, which then decreased to 1,070 (7.0%) after the restrictions. In general, identifying as a sexual minority and experiencing greater economic vulnerability were associated with higher odds of experiencing IPV during COVID-19 restrictions, which were accentuated among participants who were living with their partners. Greater stringency of COVID-19 restrictions and living in urban or semi-urban areas were associated with lower odds of experiencing IPV in some settings. The I-SHARE data suggest a substantial burden of IPV during COVID-19 restrictions. However, the restrictions were correlated with reduced IPV in some settings. There is a need for investing in specific support systems for survivors of IPV during the implementation of restrictions designed to contain infectious disease outbreaks.

RESUMO

Restricted and repetitive behaviours (RRBs) are observed in many children presenting with characteristics of autism and are frequently the targets of psychological interventions. This study used Interpretative Phenomenological Analysis (IPA) to identify positive and negative interpretations from four young adults who received behavioural interventions in their childhood designed to 'fix' RRBs. Two superordinate themes were identified: (1) Doubt, stigma and being fixed according to others, and (2) Embracing Authenticity. They highlighted juxtaposed positions from exclusion, rejection, criticism, and self-doubt in childhood, to rejecting societal censure and embracing authentic growth in adult life. As adults, though the participants recognised themselves as neurologically different from others, they redefined themselves through a lens of neurodiversity, and therefore as not needing to be fixed.

RESUMO

Atrial fibrillation (AF) is a major cause of recurrent stroke and transient ischaemic attack (TIA) in the UK. As many patients can have asymptomatic paroxysmal AF, prolonged arrhythmia monitoring is advised in selected patients following a stroke or TIA. This service evaluation assessed the clinical and potential health economic impact of prolonged arrhythmia monitoring post-stroke using R-TEST monitoring devices. This was a prospective, case-controlled, service evaluation in a single health board in the North of Scotland. Patients were included if they had a recent stroke or TIA, were in sinus rhythm, and did not have another indication for, or contraindication to, oral anticoagulation. A health economic model was developed to estimate the clinical and economic value delivered by the R-TEST monitoring. Approval to use anonymised patient data in this service evaluation was obtained. During the evaluation period, 100 consecutive patients were included. The average age was 70 ± 11 years, 46% were female. Stroke was the presenting complaint in 83% of patients with the other 17% having had a TIA. AF was detected in seven of 83 (8.4%) patients who had had a stroke and one of 17 (5.9%) patients with a TIA. Health economic modelling predicted that adoption of R-TEST monitoring has a high probability of demonstrating both clinical and economic benefits. In conclusion, developing a post-stroke arrhythmia monitoring service using R-TEST devices is feasible, effective at detecting AF, and represents a probable clinical and economic benefit.

RESUMO

AIM: To identify the impact of COVID-19 measures on sexual behaviors and sexual satisfaction in Luxembourg residents. METHODS: We conducted a cross-sectional online survey of adults (> 18 years of age) residing in Luxembourg, while COVID-19 restrictions were in place. The survey was available from January 15 to February 12, 2021 in four languages (French, German, English and Portuguese). Survey questions focused on masturbation, cuddling, condom use, sex frequency, sexting, cybersex, watching porn, and sexual satisfaction. RESULTS: 557 volunteers completed the survey (35.5% men, 64.3% women). Sexual satisfaction and sexual problems variables were assessed on 4-point Likert scales (0 = not at all/never to 3 = very/often). Sexual problems increased during the COVID-19 measures while sexual satisfaction decreased compared to before the introduction of COVID-19 restrictions (assessed retrospectively). Factors associated with increased odds of sexual satisfaction included having a steady relationship before COVID-19 restrictions, engaging in sexting, reporting good mental health and not altering alcohol intake. CONCLUSIONS: The context of the COVID-19 pandemic and the measures implemented in Luxembourg affected sexual behaviors and sexual satisfaction. Sexual and reproductive health care centers and health professionals in general should take these results into consideration when providing care. Recommendations on the importance of sexual health for general wellbeing and behaviors associated with sexual satisfaction should be offered and possibilities to experience sexuality while reducing contamination risks be discussed.

RESUMO

INTRODUCTION: Tuberculosis (TB) has become an occupational health hazard in South African hospitals where healthcare workers (HCWs) are additionally confronted daily with HIV and its associated stigma, causing a syndemic. Early TB diagnosis and treatment are vital, but the uptake of these services through occupational healthcare units (OHUs) is low. The current study hypothesises that (1) the link between HIV and TB and (2) the perceived HIV stigmatisation by colleagues create (3) a double HIV-TB stigma which increases (4) internalised TB stigma and leads to (5) a lower willingness to use OHU services for TB screening and treatment. DESIGN: A cross-sectional study using the baseline data from the HIV and TB Stigma among Healthcare workers Study (HaTSaH Study). SETTING: Six hospitals in the Free State province of South Africa. PARTICIPANTS: 820 HCWs of the six selected hospitals. RESULTS: The study results demonstrate that the co-epidemic (ß=0.399 (screening model) and ß=0.345 (treatment model)) combined (interaction effect: ß=0.133 (screening) and ß=0.132 (treatment)) with the persistent stigmatisation of HIV is altering the attitudes towards TB (ß=0.345 (screening) and ß=0.400 (treatment)), where the stigmatising views of HIV are transferred to TB-illustrating the syndemic impact. Our model demonstrated that this syndemic not only leads to higher levels of internal TB stigma (ß=0.421 (screening) and ß=0.426 (treatment)), but also to a lower willingness to use the OHU for TB screening (probit coefficient=-0.216) and treatment (probit coefficient=-0.160). Confidentiality consistently emerged as a contextual correlate of OHU use. CONCLUSIONS: Theoretically, our results confirm HIV as a 'syndemic generator' which changes the social meaning of TB in the hospital context. Practically, the study demonstrated that the syndemic of TB and HIV in a highly endemic context with stigma impacts the intended use of occupational TB services.

RESUMO

BACKGROUND: There is limited evidence to date about changes to sexual and reproductive health (SRH) during the initial wave of coronavirus disease 2019 (COVID-19). To address this gap, our team organized a multicountry, cross-sectional online survey as part of a global consortium. METHODS: Consortium research teams conducted online surveys in 30 countries. Sampling methods included convenience, online panels, and population-representative. Primary outcomes included sexual behaviors, partner violence, and SRH service use, and we compared 3 months prior to and during policy measures to mitigate COVID-19. We conducted meta-analyses for primary outcomes and graded the certainty of the evidence. RESULTS: Among 4546 respondents with casual partners, condom use stayed the same for 3374 (74.4%), and 640 (14.1%) reported a decline. Fewer respondents reported physical or sexual partner violence during COVID-19 measures (1063 of 15 144, 7.0%) compared to before COVID-19 measures (1469 of 15 887, 9.3%). COVID-19 measures impeded access to condoms (933 of 10 790, 8.7%), contraceptives (610 of 8175, 7.5%), and human immunodeficiency virus/sexually transmitted infection (HIV/STI) testing (750 of 1965, 30.7%). Pooled estimates from meta-analysis indicate that during COVID-19 measures, 32.3% (95% confidence interval [CI], 23.9%-42.1%) of people needing HIV/STI testing had hindered access, 4.4% (95% CI, 3.4%-5.4%) experienced partner violence, and 5.8% (95% CI, 5.4%-8.2%) decreased casual partner condom use (moderate certainty of evidence for each outcome). Meta-analysis findings were robust in sensitivity analyses that examined country income level, sample size, and sampling strategy. CONCLUSIONS: Open science methods are feasible to organize research studies as part of emergency responses. The initial COVID-19 wave impacted SRH behaviors and access to services across diverse global settings.

RESUMO

In March 2020, the South African government imposed a lockdown to control COVID-19 transmission. Lockdown may affect people living with HIV's (PLWH) antiretroviral therapy (ART) adherence. Data from a cluster randomised control trial was collected from 152 PLWH in Cape Town sub-districts from October 2019-March 2020 when the lockdown halted collection. Subsequently, 83 PLWH were followed-up in June-July 2020. Random effects models were used to analyse: (1) changes between baseline and follow-up and (2) correlates of adherence during lockdown. At follow-up, there was an increase in the odds of being below the poverty line and the odds of experiencing violence decreased. Measures for well-being, household functioning, stigma and HIV competency improved. Violence, depression, food insecurity, and stigma were associated with poorer ART adherence; higher well-being scores were associated with better adherence. During lockdown, governments need to ensure financial support, access to (mental) health services, and services for those experiencing violence.Clinical Trial Number: Pan African Clinical Trial Registry, PACTR201906476052236. Registered on 24 June 2019.


RESUMEN: En marzo de 2020, el gobierno sudafricano impuso un confinamiento generalizado para controlar la transmisión del COVID-19. Estas medidas pueden afectar la adherencia a la terapia antirretroviral de las personas con VIH. A partir de un ensayo aleatorio grupal se recopilan datos de 152 personas con VIH en los sub-distritos de Ciudad del Cabo entre octubre de 2019 y marzo de 2020 cuando el confinamiento detuvo la recopilación. Posteriormente, se realizó un seguimiento de 83 pacientes entre junio y julio de 2020. Se utilizaron modelos de efectos aleatorios para analizar: 1) los cambios en las variables entre la línea de base y de seguimiento; 2) covariables de adhesión al tratamiento. En el seguimiento se observa que aumentaron las probabilidades de estar por debajo del umbral de pobreza y disminuyeron las probabilidades de sufrir violencia. Las medidas de bienestar, funcionamiento del hogar, estigma e idoneidad en materia de VIH mejoraron entre la línea base y el seguimiento. Por otro lado, la violencia, la depresión, la inseguridad alimentaria y el estigma se asocian a una menor adherencia al tratamiento antirretroviral, mientras la mejora del bienestar se asocia a una mayor adherencia al tratamiento. De tal manera, se observa que durante situaciones de emergencia que requieran de confinamientos es recomendable que los gobiernos garanticen apoyo financiero, atención a la salud física y mental de manera continua, así como servicios especializados hacia quienes sufren violencia.

RESUMO

Hypertensive disorders of pregnancy (HDP) are associated with increased risk of developing cardiovascular disease (CVD) in later life. This systematic review aimed to evaluate the impact of modifiable risk factors for CVD following pregnancy on the relationship between HDP and cardiovascular health outcomes. Seven databases (Medline, CENTRAL, CINAHL, Cochrane Reviews, Embase, PsycINFO and Scopus) were searched from date of inception to July 24, 2019. Observational studies that included female adults with a history of HDP and analysed whether modifiable risk factors for CVD following pregnancy (dietary intake, physical activity, smoking status, alcohol intake, body weight and mental health status) influenced associations between HDP and cardiovascular health outcomes (morbidity, mortality or related risk markers) were eligible for inclusion. In total, 4704 articles were identified, with 11 studies included. The modifiable risk factors measured included body weight (11 studies), physical activity and dietary intake (one study) and smoking (one study). Overall, five of seven studies provided convincing evidence that the relationship between HDP and blood pressure was adversely impacted by excess body weight post-pregnancy. The current systematic review provides evidence that excess body weight post-pregnancy impacts associations between HDP and hypertension in later life. However, there is a lack of evidence exploring the impact of a variety of modifiable risk factors for CVD on associations between HDP and cardiovascular health outcomes. This evidence is imperative to inform development of effective CVD prevention interventions for women with a history of HDP.

RESUMO

Certain pathogenic genetic variants impact neurodevelopment and cause deviations from typical cognitive trajectories. Understanding variant-specific cognitive trajectories is clinically important for informed monitoring and identifying patients at risk for comorbid conditions. Here, we demonstrate a variant-specific normative chart for cognitive development for individuals with 22q11.2 deletion syndrome (22q11DS). We used IQ data from 1365 individuals with 22q11DS to construct variant-specific normative charts for cognitive development (Full Scale, Verbal, and Performance IQ). This allowed us to calculate Z-scores for each IQ datapoint. Then, we calculated the change between first and last available IQ assessments (delta Z-IQ-scores) for each individual with longitudinal IQ data (n = 708). We subsequently investigated whether using the variant-specific IQ-Z-scores would decrease required sample size to detect an effect with schizophrenia risk, as compared to standard IQ-scores. The mean Z-IQ-scores for FSIQ, VIQ, and PIQ were close to 0, indicating that participants had IQ-scores as predicted by the normative chart. The mean delta-Z-IQ-scores were equally close to 0, demonstrating a good fit of the normative chart and indicating that, as a group, individuals with 22q11DS show a decline in IQ-scores as they grow into adulthood. Using variant-specific IQ-Z-scores resulted in 30% decrease of required sample size, as compared to the standard IQ-based approach, to detect the association between IQ-decline and schizophrenia (p < 0.01). Our findings suggest that using variant-specific normative IQ data significantly reduces required sample size in a research context, and may facilitate a more clinically informative interpretation of IQ data. This approach allows identification of individuals that deviate from their expected, variant-specific, trajectory. This group may be at increased risk for comorbid conditions, such as schizophrenia in the case of 22q11DS.

RESUMO

BACKGROUND: In Australia, using non-invasive prenatal testing (NIPT) to screen for fetal abnormalities is becoming more commonplace. However, there is a lack of standardised procedures surrounding pre-test counselling. This holds the potential for variability in pregnant people's experiences when undergoing NIPT, which subsequently may impact their ability to make informed decisions surrounding NIPT results. AIM: This study sought to characterise the experiences of Australian women undergoing NIPT, including perceptions of informed choice, counselling experiences and decision to undergo NIPT. MATERIALS AND METHODS: Australian women who had been recently pregnant (n = 94) completed an online survey which assessed: their knowledge of and attitude toward NIPT; satisfaction with counselling; satisfaction with their decision; and decisional conflict to undergo NIPT. The survey also allowed participants to provide qualitative information about their counselling experience and reasons for undergoing NIPT. RESULTS: Overall, participants had good knowledge of and positive attitudes toward NIPT, experienced low decisional conflict and were overall satisfied with their counselling experience and decision to undergo NIPT. However, some participants expressed dissatisfaction with the lack of information provided, and biased language, by counselling providers. The desire to be informed was the most frequent reason for undergoing NIPT. CONCLUSION: The provision of accurate and objective information in pre-test counselling is important to reduce decisional conflict and improve satisfaction with the decision to undergo NIPT. It is recommended counselling providers present pregnant people with neutral, objective, and accurate information at the time of pre-test counselling.

RESUMO

OBJECTIVE: Maternal asthma often complicates pregnancy and is linked with poorer quality of life. Additionally, individuals with asthma are at an increased risk of depression and anxiety. We examined whether asthma during pregnancy is related to parenting stress in the first year postpartum and if this relationship varies with level of asthma control. METHODS: This cohort survey-based study included mothers with (n = 157) and without (n = 79) asthma. Mothers with asthma participated in this study following participation in a randomized controlled trial of a novel asthma management strategy during pregnancy. Mothers completed the Parenting Stress Index - Short Form during the first 12 months postpartum. Mothers with asthma also completed the Asthma Control Questionnaire. RESULTS: Parenting stress did not differ between mothers with and without asthma. Additionally, for mothers with asthma, there were no differences in levels of parenting stress based on asthma control. CONCLUSIONS: This study suggests that mothers with asthma are not at an increased risk for excessive parenting stress. However, due to response and sampling bias, levels of parenting stress in asthmatic mothers may be underreported in our sample.

RESUMO

In acquired brain injury (ABI), social cognition is a contributing factor to the changes observed in functional outcomes. However, progress in assessing and understanding social cognitive impairments is limited by a lack of consistency in terminology and the proliferation in assessment tools, leading to a lack of consensus on what should be assessed and how. This review aims to examine the domains of social cognition commonly assessed in ABI, the assessment tools used, and the appropriateness of these tools for researchers and clinicians. Using the Arksey and O'Malley scoping review methodology, 367 articles reporting results from 10,930 people with an ABI met our inclusion criteria. The five most commonly assessed domains of social cognition were emotion perception, theory of mind, social communication, identity recognition and empathy. The most commonly used measure of these domains included: the Ekman and Friesen photo series, Faux Pas Recognition Test, La Trobe Communication Questionnaire, Benton Facial Recognition Test and the Interpersonal Reactivity Index. There are well-validated measures readily available that are underused in favour of non-standardized measures clinically or the development of one's own measure in research. The appropriateness of the identified measure for research and clinical use was discussed, including suggestions for future research.
