Examining the relationship between psychosocial adversity and inhibitory control: an fMRI study of children growing up in extreme poverty

Exposure to psychosocial adversity (PA) is associated with poor behavioral, physical, and mental health outcomes in adulthood. Growing evidence suggests that deficits in executive functions may in part moderate these outcomes, with inhibitory control as an example of such a putative moderator. However, much of the literature examining the development of inhibitory control has been based on children in higher resource environments, and little is known how growing up in a low resource setting might exacerbate the link between inhibitory control and health outcomes. In this context we collected fMRI data during a Go/No-Go inhibitory control task and PA variables for 68 children 5 to 7 years of age living in Dhaka, Bangladesh, an area with a high prevalence of PA. The children's mothers completed behavioral questionnaires to assess the child's PA and their own PA. Whole-brain activation underlying inhibitory control was examined using the No-Go versus Go contrast, and associations with PA variables were assessed using whole-brain regressions. Childhood neglect was associated with weaker activation in the right posterior cingulate, whereas greater family conflict, economic stress, and maternal PA factors were associated with greater activation in the left medial frontal gyrus, right superior and middle frontal gyrus, and left cingulate gyrus. These data suggest that neural networks supporting inhibitory control processes may vary as a function of exposure to different types of PA, particularly between those related to threat and deprivation. Furthermore, increased activation in children with greater PA may serve as a compensatory mechanism, allowing them to maintain similar behavioral task performance.

Maternal and environmental Impact assessment on Neurodevelopment in Early childhood years (MINE): a prospective cohort study protocol from a low, middle-income country

INTRODUCTION

Environmental and psychosocial adversities negatively impact children's developmental outcomes. When these factors are experienced in early childhood-a sensitive period of development-the developing brain can be altered. While these associations have been drawn in high-income countries, it is necessary to understand child growth, neurodevelopment, and the role of environmental factors in developmental trajectories in low-income settings. The objective of this study is to longitudinally assess how demographic factors, maternal health, maternal development, and child health, are related to child development on a behavioural, cognitive, and neuroimaging level in low-socioeconomic communities.

METHODS AND ANALYSIS

Mother-child dyads will be identified in the peri-urban field sites of Rehri Goth and Ibrahim Hyderi, Karachi, Pakistan. Dyads will undergo yearly assessments for 4 years beginning when the child is 1 month, 3 months or 6 months of age (+≤30 days of age) (depending on group assignment). Maternal assessments include anthropometry, behavioural, cognitive, and developmental assessments (Edinburgh Postnatal Depression Scale; Parenting Stress Index; Maternal Autonomy Index; Hurt, Insult, Threaten, Scream Tool; Reynolds Intellectual Assessment Scales (RIAS)), and biological samples collection (breast milk, blood, stool, hair). Children's assessments include anthropometry, developmental assessments (Global Scales for Early Development (GSED); RIAS), MRI brain assessments, and biological sample collection (blood, stool, hair). Using cross-sectional and longitudinal data with statistical analysis tools, associations will be quantified between brain structure (MRI) and connectivity (resting state connectivity and diffusion tensor imaging), general cognitive skills (RIAS, GSED) and environmental influences (nutrition via biological samples, maternal mental health via questionnaires) through repeated measures analysis of variance tests and χ2 tests. Quantile regression and cortical analyses will be conducted to understand how demographic factors are related to the associations found.

ETHICS AND DISSEMINATION

The study has received ethical approval from the Aga Khan University Ethics Review Committee. The study's findings will be disseminated through scientific publications and project summaries for the participants.

High prevalence of food insecurity in peri-urban communities in Karachi, Pakistan: The flood aftermath

BACKGROUND

Food insecurity (FI) is at a steep risk, especially in low middle-income countries. FI is further compounded in areas that experience environmental and economic instability, thus a reassessment in such critical times is required for burden estimation and to propose targeted interventions.

AIMS

The objectives of this study were to assess the prevalence of, and sociodemographic factors associated with FI, as well as the coping strategies utilized in response to FI in peri-urban communities in Karachi, Pakistan.

METHODS

We conducted a cross-sectional survey from November-December 2022 on 400 households in four peri-urban communities in Karachi, Pakistan. The Household Food Insecurity Access Scale (HFIAS) and reduced Coping Strategies Index (rCSI) questionnaire were used to assess FI. A Poisson regression was used to assess associations between sociodemographic factors and FI.

RESULTS

The overall prevalence of FI was found to be 60.2% (n = 241) of which 33.8% (n = 135) were severely food insecure. Age, women's and breadwinners' education, women's occupation, and parity were significantly associated with FI. Participants reported relying on less expensive foods (44%) and borrowing food or help from others (35%) as the most common coping strategies overall in the FI households.

CONCLUSION

With more than half the households facing FI and adopting severe measures to cope in these communities, it is pivotal to design and test interventions that can withstand economic and climate catastrophes and help ensure a safety need for food security for the most vulnerable.

Social media usage among health care providers

Objective

The objective of this study was to evaluate the use of social media among healthcare workers in an attempt to identify how it affects the quality of patient care.

Results

An anonymous survey of 35 questions was conducted in South Texas, on 366 healthcare workers. Of the 97% of people who reported owning electronic devices, 87.9% indicated that they used social media. These healthcare workers indicated that they spent approximately 1 h on social media every day. The healthcare workers below the age of 40 were more involved in social media compared to those above 40 (p < 0.05). The use of social media among physicians and nurses was noted to be identical (88% for each group), and both groups encouraged their patients to research their clinical conditions on social media (p < 0.05). A higher number of physicians reported awareness of a social media policy in their hospital compared to nurses (p < 0.05). However, a large proportion of healthcare workers (40%) were unaware of their workplace policy, which could potentially cause a privacy breach of confidential medical information. Further studies are required to evaluate specific effects of these findings on the quality of patient care.

Acute Fibrinous and Organizing Pneumonia: A Case Report and Review of the Literature

BACKGROUND Acute fibrinous organizing pneumonia (AFOP) is a rare condition of the lung that is associated with acute lung injury, and has a poor prognosis. AFOP is characterized histologically by intra-alveolar fibrin. AFOP has been described to be associated with lung infections, connective tissue disorders, drugs, toxic environmental exposure, and in lung transplantation. However, most cases of AFOP remain idiopathic, and because the condition can present with a wide variety of clinical manifestations, open lung biopsy or video-assisted thoracoscopic (VAT) lung biopsy is necessary for the diagnosis. Currently, treatments for AFOP remain under investigation. CASE REPORT A 35-year-old woman presented with a cough and dyspnea, and was initially diagnosed to have pneumonia.  Due to the progression of her symptoms and increasing respiratory failure she underwent video-assisted thoracoscopic (VAT) biopsy and was diagnosed with AFOP, 19 days following hospital admission. She was treated with mechanical ventilation, intravenous steroids, and cyclophosphamide. She required tracheostomy after 14 days of mechanical ventilation and died two weeks later. CONCLUSIONS AFOP is an uncommon clinical condition, with a poor prognosis, which often has a delay in diagnosis. Some patients benefit from steroids and immunosuppressive therapy. Currently, new treatments for AFOP are under investigation.

Effect of animated movie in combating child sleep health problems

Objective

Sleep deprivation among teens is a major health issue. Only 15% of teens get 8.5 h of sleep on school nights. Sleep deprivation can lead to poor grades, sleepiness and moodiness. We undertook a study to assess the prevalence of sleep habit disturbance among elementary school students in South Texas with Hispanic ethnicity predominance. We also found how much a video based on sleep education had an impact on these children.

Method

Once the Corpus Christi Independent School District (CCISD) approved the collection of baseline sleep data, questionnaires were administered using the Children’s Sleep Habit Questionnaire (CSHQ.) These questionnaires were distributed prior to the viewing of the educational and animated movie KNIGHTS (Keep Nurturing and Inspiring Good Habits in Teen Sleep). Four months later, a random follow-up was performed and the children were requested to respond to the same CSHQ.

Results

264 children from two elementary schools participated in this educational program. At baseline, 55.56% of the children had trouble sleeping. When the questionnaire was administered four months later, only 23.26% (p < 0.05) had trouble sleeping. Additionally, at baseline, approximately 60–70% children had some baseline bedtime resistance, anxiety dealing with sleep, issues with sleep duration and/or awakenings in the middle of the night. In the follow up questionnaire, results showed significant improvements in overall sleep habits, bedtime resistance, sleep anxiety and night awakenings amongst students (p < 0.05). However, no significant differences were seen in sleep duration and daytime sleepiness.

Conclusion

Sleep deprivation and good sleep habits remain as a pervasive challenge among elementary school students. Administering an animated video about sleep education along with a provider-based education may be an effective tool for educating elementary school students and decreasing the prevalence of these sleep-related issues. Future prospective randomized studies are suggested.
