Outcome after successful resuscitation of babies born with apgar scores of 0 at both 1 and 5 minutes

OBJECTIVE

Our purpose was to evaluate the outcome of infants who underwent successful resuscitation after initial Apgar scores of 0 at both 1 and 5 minutes.

STUDY DESIGN

Eligible infants were identified through the perinatal database at the University of Tennessee, Memphis. Hospital records and long-term outcomes, where available, of babies who met the above criteria occurring between January 1986 and February 1999 were reviewed.

RESULTS

Thirty-three of 81,603 infants (0.4/1000 births) met our study criteria. Twenty-two (67%) babies died during hospitalization. Mortality decreased significantly from 100% for babies with a birth weight of <750 g to 38% for those weighing > or =2500 g at birth (P =.03). All 6 babies delivered before 26 weeks' gestation died. The incidence of 10-minute Apgar scores >0 was significantly higher among survivors than among those who subsequently died (82% vs 33%, P <.05). Nine survivors had hypoxic-ischemic encephalopathy diagnosed before discharge. Of the 7 infants with available follow-up, 4 had significant persisting morbidity. Two infants had normal neurologic examinations at follow-up.

CONCLUSION

Survival in babies born with 1- and 5-minute Apgar scores of 0 is predicted by birth weight, gestational age, and 10-minute Apgar score. Long-term sequelae are common but not ensured.

Changing relationships between smoking and psychiatric disorders across twentieth century birth cohorts: clinical and research implications

As the risks of tobacco use become recognized and smoking becomes stigmatized, new smokers may be increasingly driven to smoke by biological or genetic vulnerabilities rather than social desirability. Given that genetic risk for deviant proneness is shared across other psychiatric and addictive disorders, we predicted that as rates of smoking decreased through the latter half of the twentieth century, associations between smoking and psychopathology would increase. Participants (N=25 412) from a large US study-the National Epidemiologic Survey on Alcohol and Related Conditions, NESARC-were interviewed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV Version (AUDADIS-IV) and classified into one of five birth cohort decades (1940s to 1980s) and three smoking history (nonsmokers, never-dependent smokers and ever-dependent smokers) groups. We found that the prevalence of smoking decreased across the five birth cohorts, but associations of smoking with drug and AUDs, attention-deficit hyperactivity disorder, bipolar disorder and antisocial personality disorder, each increased monotonically in more recently born cohorts, even after adjusting for concurrent demographic and socioeconomic changes. For drug and AUDs, increases were observed among smokers both with and without a history of nicotine dependence; for other outcomes, increases were entirely driven by nicotine-dependent smokers. Findings suggest that smokers in more recent cohorts have disproportionately high psychiatric vulnerability, and may benefit from greater mental health screenings. Differentiating between casual and dependent smokers may further help prioritize those at greatest risk. Researchers should also be aware of potential variation in psychiatric comorbidity based on cohort of birth when defining groups of smokers, to minimize confounding.

Representation of nociceptive stimuli in primary sensory cortex

Using fMRI, we observed cortical activity associated with nociceptive hot and cold sensations applied to hand and foot that are not spatially restricted to the corresponding regions of the primary somatosensory cortex (SI). Hot (55-57 degrees C) and cold (0-2 degrees C) tactile stimuli were applied separately to the right hand and foot of eight right-handed subjects. Although somatotopic mapping of hand and foot was observed as expected based on the Penfield homunculus, activations associated with hot during both hand and foot stimulation and subsequently, cold, activated regions unique to each thermal modality irrespective of the body part. This distributed system for thermal information is present at both nociceptive and more neutral thermal intensities (i.e. warm and cool sensations) indicating the presence of distributed sensory processing associated with thermal-related sensations in human primary sensorimotor cortex.

A comparison between screened NIMH and clinically interviewed control samples on neuroticism and extraversion

The National Institute of Mental Health (NIMH) has supported the collection of DNA samples on over 4000 subjects for use primarily as controls in psychiatric genetic studies. These subjects, though screened online, were not directly interviewed or assessed on family history. We compared this sample to one that was directly interviewed using structured diagnostic assessments on comparable measures of neuroticism and extraversion. The screened sample completed an online self-report based on the Composite International Diagnostic Instrument Short-Form (CIDI-SF). The interviewed sample was assessed by clinically trained personnel using the Schedule for Affective Disorders and Schizophrenia (SADS-LA-IV) and Family History Screen; final diagnoses were made blind to trait scores by a clinician using the best-estimate procedure. Neuroticism and extraversion were assessed on the NEO five-factor inventory (NEO-FFI) and the revised Eysenck Personality Questionnaire short form (EPQ-R). We found that subjects in the NIMH-screened sample who did not report any psychiatric symptoms on the self-report were indistinguishable from interviewed diagnosis free and family history negative controls on neuroticism and extraversion. Subjects in the screened sample who screened positive for anxiety disorders, however, deviated significantly on these measures both from the screened subjects with no self-reported symptoms, as well as from subjects in the interviewed sample diagnosed with comparable disorders. These findings suggest that control groups generated from the NIMH sample should ideally be restricted to subjects free of any self-reported symptoms, regardless of the disorder being addressed, in order to maximize their reflection of diagnosis-free populations.

Multidrug-resistant typhoid fever

One hundred children (consecutive) with positive blood culture for Salmonella typhi were studied for clinical profile and complications. The common clinical features were fever (100%), vomiting (58%), abdominal pain (48%), cough (22%) and loose stools (14%) and the Widal test was positive in 75% patients. Eighty per cent of the salmonella isolates were resistant to amoxycillin, chloramphenicol and co-trimoxazole drugs, but all were sensitive to ciprofloxacin and ceftriaxone. Forty patients developed complications: encephalopathy (18), melaena (12), haematemesis (10), epistaxis (4), hepatitis (4), acalculous cholecystitis (4), bowel perforation (3) and nephritis (2). Complications were more frequent in children with multidrug-resistant typhoid. The final antibiotic required to render the children afebrile included ciprofloxacin (80), ceftriaxone, amoxycillin (4), chloramphenicol (4), amoxycillin and gentamicin (4), amoxycillin with chloramphenicol (2), and furazolidone (2). The defervesence time was least with ceftriaxone and greatest with amoxycillin. All the affected children made a complete recovery.

Trends in antidepressant use among children and adolescents: a Scandinavian drug utilization study

OBJECTIVE

To compare antidepressant utilization in individuals aged 5-19 years from the Scandinavian countries.

METHODS

A population-based drug utilization study using publicly available data of antidepressant use from Denmark, Norway, and Sweden.

RESULTS

In the study period from 2007 to 2017, the proportion of antidepressant users increased markedly in Sweden (9.3-18.0/1000) compared to Norway (5.1-7.6/1000) and Denmark (9.3-7.5/1000). In 2017, the cumulated defined daily doses (DDD) of selective serotonin reuptake inhibitors were 5611/1000 inhabitants in Sweden, 2709/1000 in Denmark, and 1848/1000 in Norway. The use of 'other antidepressants' (ATC code N06AX) also increased in Sweden with a higher DDD in 2017 (497/1000) compared to Denmark (225/1000) and Norway (170/1000). The use of tricyclic antidepressants was generally low in 2017 with DDDs ranging between 30-42 per 1000. The proportion of antidepressant users was highest among 15- to 19-year-old individuals. Girls were more likely to receive treatment than boys, and the treated female/male ratios per 1000 were similar in Sweden (2.39), Denmark (2.44), and Norway (2.63).

CONCLUSION

Even in highly comparable healthcare systems like the Scandinavian countries', variation in antidepressant use is considerable. Swedish children and adolescents have a markedly higher and still increasing use of antidepressants compared to Danish and Norwegian peers.

Maternal prenatal stress and postnatal depressive symptoms: discrepancy between mother and teacher reports of toddler psychological problems

PURPOSE

Maternal prenatal stress and postnatal depression are reported to increase the risk for early offspring psychological problems. We examined whether these two stressors predicted toddler emotional or behavioral problems based on the mother and teacher reports, respectively.

METHODS

A longitudinal study within the Odense Child Cohort (OCC). Prenatal stress was assessed (gestation week 28) using Cohen's Perceived Stress Scale (PSS). Depressive symptoms were assessed (3 months after birth) using the Edinburgh Postnatal Depression Scale (EPDS). Behavioral and emotional problems were assessed by mothers using the preschool version of Child Behaviour Checklist (CBCL) and by teachers using the caregiver-teacher report form (CTR-F).

RESULTS

N = 1302 mother-child dyads were included. CBCL (N = 1302) was collected at 29 months (SD 5.3) and C-TRF (N = 989) at 32.6 months (SD 6.9). N = 70 mothers (5.4%) were at high risk for postnatal depression (EPDS score > 12). Generalized additive models showed that prenatal stress (increase of + 1 on PSS-10 total score) predicted an increase in CBCL (+ 0.011) and C-TRF (+ 0.015) total scores. Postnatal depressive symptoms (increase of + 1 on EPDS total score) only predicted an increase in CBCL total score (+ 0.026).

CONCLUSION

Prenatal maternal stress was a significant predictor of both mother and teacher reported toddler emotional and behavioral problems, although effect sizes were small. Postnatal depressive symptoms were associated with increased maternal (but not teacher) reporting of toddler problems. Mothers reported more toddler psychological problems than teachers, and the mother-teacher discrepancy was positively correlated to maternal postnatal depressive symptoms.

Vitamin A supplementation in post-measles complications

One-hundred-and-seventy-seven children with post-measles complications divided into two comparable groups were studied for the effect of Vit.A Supplementation. Eighty-nine children received Vit.A in doses of 200,000 units daily on two consecutive days in addition to antibacterials and other supportive care and 88 did not reveice Vit.A. The case fatality rate was 16 per cent in those who received VIT.A, while the same was 32 per cent in those who did not receive Vit.A (P < 0.02). There was no statistical difference in the mortality rate among two groups when the children were suffering from severe malnutrition or encephalopathy (P > 0.1).

Prediction of post-partum depression and anxiety based on clinical interviews and symptom self-reports of depression and anxiety during pregnancy

Introduction

The tools used to evaluate mental health during pregnancy matter. Their efficacy in identifying symptom severity enables better predictions of postpartum mental health. The Mother & Youth: Research on Neurodevelopment & behaviour (MYRNA) cohort is an NIH funded longitudinal cohort from Sherbrooke, Canada studying the effects of pregnant women’s mental health.

Objectives

We examine which mental health tools will better gauge depression and anxiety during pregnancy based on predicting postpartum outcomes. Our hypothesis is that an approach combining a clinical interview with self-report questionnaires may predict mental health in postpartum women.

Methods

Participants’ mental health is evaluated by the SCID-5-RV, a lifetime interview administered at 30 weeks and monthly questionnaires including PHQ-9 and GAD-7. Participants are in the depression/anxiety group if they either pass all the criteria in the SCID during pregnancy or have an average PHQ-9 or GAD-7 score greater than 7. The Edinburgh Postnatal Depression Scale (EPDS) and the Perceived Stress Scale (PSS) are the outcome variables.

Results

PHQ-9 was correlated with EPDS, r(220)= .38, p< .01, and GAD-7 was correlated with PSS, r(213)= .56, p< .01. SCID results only had a significant effect on PSS, F(3,220)= 3.77, p= .01 and not with EPDS, F(3,219)= 1.08, p= .36. When the self-report measures and interview were combined significant effects were seen for both the EPDS, F(1,222)= 18.71, p< .01 and the PSS, F(1,223)= 34.94, p<.01.

Conclusions

Preliminary results show significant associations between measures administered during pregnancy and postpartum measures. Prediction models based on classification will be analyzed once more data is collected.

Depression and cognition are associated with lipid dysregulation in both a multigenerational study of depression and the National Health and Nutrition Examination Survey

Chronic dysregulation of peripheral lipids has been found to be associated with depression and cognition, but their interaction has not been investigated. Growing evidence has highlighted the association between peripheral lipoprotein levels with depression and cognition with inconsistent results. We assessed the association between peripheral lipids, depression, and cognition while evaluating their potential interactions using robust clinically relevant predictors such as lipoprotein levels and chronic medical disorders that dysregulate lipoproteins. We report an association between peripheral lipids, depression, and cognition, suggesting a common underlying biological mechanism driven by lipid dysregulation in two independent studies. Analysis of a longitudinal study of a cohort at high or low familial risk for major depressive disorder (MDD) (n = 526) found metabolic diseases, including diabetes, hypertension, and other cardiovascular diseases, were associated with MDD and cognitive outcomes. Investigating a cross-sectional population survey of adults in the National Health and Nutrition Examination Survey 2011-2014 (NHANES) (n = 2377), depression was found to be associated with high density lipoprotein (HDL) and cognitive assessments. In the familial risk study, medical conditions were found to be associated with chronic lipid dysregulation and were significantly associated with MDD using the structural equation model. A positive association between chronic lipid dysregulation and cognitive scores was found in an exploratory analysis of the familial risk study. In a complementary study, analysis of NHANES revealed a positive association of HDL levels with cognition. Further analysis of the NHANES cohort indicated that depression status mediated the interaction between HDL levels and cognitive tests. Importantly, the protective effect of HDL on cognition was absent in those with depressive symptoms, which may ultimately result in worse outcomes leading to cognitive decline. These findings highlight the potential for the early predictive value of medical conditions with chronic lipid dyshomeostasis for the risk of depression and cognitive decline.

Prenatal depression outcomes in the next generation: A critical review of recent DOHaD studies and recommendations for future research

Prenatal depression, a common pregnancy-related risk with a prevalence of 10-20 %, may affect in utero development and socioemotional and neurodevelopmental outcomes in the next generation. Although there is a growing body of work that suggests prenatal depression has an independent and long-lasting effect on offspring outcomes, important questions remain, and findings often do not converge. The present review examines work carried out in the last decade, with an emphasis on studies focusing on mechanisms and leveraging innovative technologies and study designs to fill in gaps in research. Overall, the past decade of research continues to suggest that prenatal depression increases risk for offspring socioemotional problems and may alter early brain development by affecting maternal-fetal physiology during pregnancy. However, important limitations remain; lack of diversity in study samples, inconsistent consideration of potential confounders (e.g., genetics, postnatal depression, parenting), and restriction of examination to narrow time windows and single exposures. On the other hand, exciting work has begun uncovering potential mechanisms underlying transmission, including alterations in mitochondria functioning, epigenetics, and the prenatal microbiome. We review the evidence to date, identify limitations, and suggest strategies for the next decade of research to detect mechanisms as well as sources of plasticity and resilience to ensure this work translates into meaningful, actionable science that improves the lives of families.
