Identifying developmental disability in national surveys: Addressing the knowledge gap with special education histories

BackgroundIn the United States nearly 20% of children ages 12–17 have developmental disorders. Some attain population-based developmental milestones after a delay, or increase functioning through special education, medication, technology, or therapy. Others have severe lasting impairments. An indicator identifying those groups in surveys of adults could help shape policies to improve lives.HypothesesWe hypothesized that survey histories of special education could indicate functional status levels.MethodsData were from the nationally representative Panel Study of Income Dynamics (1997–2017, n = 2745). With measures of diagnoses, behaviors, functional status, service use, and adult outcomes, we tested three special education groups as indicators of: (1) no impairment (no special education), (2) disorders, developmental diagnoses that adversely affect educational performance, but with development after a period of delay or only moderate disability, indicated by transfer from special education; and (3) severe lasting disability, the diagnoses combined with life-long needs for supports or services, with limitations in areas including self-care, mobility, and capacity for independent living, indicated by special education in the individual's final year of school.ResultsAcross the special education groups, from no impairment to severe lasting disability, there were trends of: increasing severe and lasting disability (respectively 4.8%, 35.6%, 76.4%); increasing special services use (13.5%, 43.1%, 83.7%); increasing severe emotional disorders (2.3%, 11.3%, 17.9%); lower percentages attaining at least an associate's degree by age 25 (42.1%, 20.7%, and 8.9%); and more chronic diseases.ConclusionsSpecial education histories provide a useful indicator of developmental disability impairment levels in adults.     

The landscape of international oral and maxillofacial surgery collaborations from 1996 to 2020: a scoping review of the published literature

The emerging field of global oral and maxillofacial surgery (OMS) aims to improve worldwide access to safe, timely, and affordable OMS care. However, there exists a dearth of literature thoroughly detailing the scope of academic global OMS collaborations between high-income countries (HICs) and low- and/or lower middle-income countries (LICs/LMICs). This scoping review was performed to characterize the landscape of global academic OMS collaborations between HICs and LICs/LMICs. A five-stage methodological framework was used. Academic global OMS collaborations from 1996 to 2020 were identified via an electronic database and grey literature review. A total 1318 articles were identified on December 17, 2020. Following the application of inclusion and exclusion criteria, 71 articles describing 81 unique global OMS academic collaborations were included in the final analysis. The most common HIC was the United States (44.4%); the majority of LIC/LMICs were within Africa (45.8%). Of the total interventions, 89.6% improved LIC/LMIC capacity development, and surgical (43.8%) interventions were the most common. By serving as a central report on current and past academic collaborations in global OMS, this review helps identify areas in need of surgical capacity building, lays the foundation for future research efforts on the topic, and serves as a resource for individuals aiming to become involved in global OMS.

Association of psychosocial adversity and social information processing in children raised in a low-resource setting: an fNIRS study

Social cognition skills and socioemotional development are compromised in children growing up in low SES contexts, however, the mechanisms underlying this association remain unknown. Exposure to psychosocial risk factors early in life alters the child’s social milieu and in turn, could lead to atypical processing of social stimuli. In this study, we used functional Near Infrared Spectroscopy (fNIRS) to measure cortical responses to a social discrimination task in children raised in a low-resource setting at 6, 24, and 36 months. In addition, we assessed the relation between cortical responses to social and non-social information with psychosocial risk factors assessed using the Childhood Psychosocial Adversity Scale (CPAS). In line with previous findings, we observed specialization to social stimuli in cortical regions in all age groups. In addition, we found that risk factors were associated with social discrimination at 24 months (intimate partner violence and verbal abuse and family conflict) and 36 months (verbal abuse and family conflict and maternal depression) but not at 6 months. Overall, the results show that exposure to psychosocial adversity has more impact on social information processing in toddlerhood than earlier in infancy     

Quality improvement training for burn care in low-and middle-income countries: A pilot course for nurses

BackgroundThere is an urgent need to empower practitioners to undertake quality improvement (QI) projects in burn services in low-middle income countries (LMICs). We piloted a course aimed to equip nurses working in these environments with the knowledge and skills to undertake such projects.MethodsEight nurses from five burns services across Malawi and Ethiopia took part in this pilot course, which was evaluated using a range of methods, including interviews and focus group discussions.ResultsCourse evaluations reported that interactive activities were successful in supporting participants to devise QI projects. Appropriate online platforms were integral to creating a community of practice and maintaining engagement. Facilitators to a successful QI project were active individuals, supportive leadership, collaboration, effective knowledge sharing and demonstrable advantages of any proposed change. Barriers included: staff attitudes, poor leadership, negative culture towards training, resource limitations, staff rotation and poor access to information to guide practice.ConclusionsThe course demonstrated that by bringing nurses together, through interactive teaching and online forums, a supportive community of practice can be created. Future work will include investigating ways to scale up access to the course so staff can be supported to initiate and lead quality improvement in LMIC burn services.     

Women living with HIV in high‐income settings and breastfeeding

Guidelines in high‐income settings recommend breastfeeding avoidance amongst women living with HIV (WLWH). Increasingly, WLWH in high‐income settings, who are well‐treated with fully suppressed viral loads, are choosing to breastfeed their infants, even with these recommendations. The purpose of this article is to review existing research and guidance on infant feeding amongst WLWH in high‐income countries and to identify gaps in this evidence that require further investigation. Current evidence on the risk of HIV transmission through breastfeeding in the context of antiretroviral therapy (ART), the significance of cell‐associated virus, transmission risk factors, retention in care and adherence postpartum, infant prophylaxis and antiretroviral exposure, and monitoring of the breastfeeding WLWH are summarized. A latent HIV reservoir is persistently present in breast milk, even in the context of ART. Thus, suppressive maternal ART significantly reduces, but does not eliminate, the risk of postnatal transmission of HIV. There are currently limited data to guide the optimal frequency of virologic monitoring and the clinical actions to take in case of maternal detectable viral load whilst breastfeeding. Moreover, retention in care and adherence to ART in the postpartum period may be difficult and more research is needed to understand what clinical and psychosocial support would benefit these mothers so that successful engagement in care can be achieved. The long‐term effects of antiretroviral drug exposure in the infants also need further exploration. Thus, there is a need for collecting enhanced surveillance data on WLWH who breastfeed and their infants to augment clinical guidance in high‐income settings.
