In low- and middle-income countries, large numbers of children are involved in work. Whilst studies have shown that child labour may be harmful to children's physical health, little is known about child labour's effects on mental health. It is important to understand the relationship between work and mental health problems during childhood, and identify possible risk factors for poorer mental health. A systematic literature review was conducted. Published papers in any language that compared the mental health of children (<18?years) who had been exposed to work with those who had not been exposed to work were included. Twelve published observational studies on the association between child labour and general psychopathology, internalising and externalising problems were identified. Child labour was found to be strongly associated with poor mental health outcomes in seven studies. More significant associations were found between child labour and internalising problems than externalising problems. The burden of poor mental health as a result of child labour is significant given the numbers of children in work. Risk factors for poorer mental health were involvement in domestic labour, younger age, and greater intensity of work, which could be due to the potential of child labour to cause isolation, low self-esteem, and perception of an external locus of control. The risk factors suggested by this review will have implications for policy makers. Additional research is needed in low-income countries, risk factors and also into the potential psychological benefits of low levels of work

This review aimed to determine whether the algorithms used in closed loop automated oxygen control systems influenced their efficacy and whether use of the systems reduced relevant, long-term neonatal complications. Methods: A literature search was conducted using PubMed and Google Scholar. The search terms were 'closed loop' or 'automat*', 'oxygen' and 'neonat*'.Results: Eighteen studies were identified: sixteen comparison clinical studies, an observational study and an animal study. Overall, closed loop automated oxygen control was associated with an increased percentage of time spent within the target oxygen saturation range and there were fewer manual adjustments to the inspired oxygen concentration when compared with manual oxygen control. The systems were effective in infants on non-invasive respiratory support or mechanically ventilated, but no study included term-born infants. No long-term data were available to determine if complications of oxygen toxicity were reduced. Conclusion:Closed loop automated oxygen control has been shown in short term trials including preterm and low birth weight infants to improve target saturation achievement. Whether long-term outcomes will be improved with their use requires investigation.

Aim To determine whether closed loop automated oxygen control resulted in a reduction in the duration and severity of desaturation episodes and the number of blood gases and chest radiographs in preterm, ventilated infants. Methods Infants were studied on two consecutive days for 12 hours on each day. They were randomised to receive standard care (standard period) or standard care with a closed loop automated oxygen control system (automated oxygen control period) first. Results Twenty‐four infants with a median gestational age of 25.7 (range 23.1‐32.6) weeks were studied at a median postconceptional age of 27.4 (range 24.3‐34.9) weeks. During the automated oxygen control period, there were fewer desaturations that lasted >30 seconds (P = .032) or >60 seconds (P = .002), infants spent a higher proportion of the time within their target SpO2 range during the automated oxygen control period (P < .001), and fewer manual adjustments were made to the inspired oxygen concentration (mean 0.58 vs mean 11.29) (P < .001). There were no significant differences in the number of blood gases (P = .872) or chest radiographs (P = .366) between the two periods. Conclusion Closed loop automated oxygen delivery resulted in fewer prolonged desaturations with more time spent in the targeted oxygen range.

ObjectivesThe World Health Organisation (WHO) has highlighted a marked trend for worse pregnancy-related indicators in migrants, such as maternal and neonatal morbidity and mortality, poor mental health and suboptimal care. The aim of this study was to determine whether such adverse outcomes occurred in refugees who moved to high income countries by comparing their antenatal and perinatal outcomes to those of non-immigrant women.MethodsA literature search was undertaken. Embase and Medline databases were searched using Ovid. Search terms included “refugee”, “pregnan*” or “neonat*”, and “outcome”.ResultsThe search yielded 194 papers, 23 were included in the final analysis. All the papers included were either retrospective cohort or cross-sectional studies. The refugees studied originated from a wide variety of source countries, including Eritrea, Somalia, Afghanistan, Iraq, and Syria. Refugee women were more likely to be socially disadvantaged, but less likely to smoke or take illegal drugs during pregnancy. Refugee women were more likely to have poor, late, or no attendance at antenatal care. Miscarriages and stillbirth were more common amongst refugee women than non-refugees. Perinatal mortality was higher among refugees.ConclusionsDespite better health care services in high income countries, refugee mothers still had worse outcomes. This may be explained by their late or lack of attendance to antenatal care.

BackgroundOur aim was to determine the prevalence of tobacco smoking and e-cigarettes and cannabis use during pregnancy, whether these were influenced by ethnicity, and their relationship to perinatal outcomes.MethodsA study was carried out in 4465 infants whose mothers delivered during 2017 and 2018. Self-reported maternal smoking, e-cigarette and cannabis use at booking were recorded. Outcome measures were birthweight and head circumference z-scores and admission to the neonatal intensive care unit (NICU).ResultsTwo hundred and five women reported smoking cigarettes (4.7%), five were using e-cigarettes (0.11%) and 106 were using cannabis (2.43%). Women were most likely to smoke if young (15–19 years old) or from a mixed-race or White background. Cigarette smoking was associated with a lower mean z-score for birthweight (−0.587 vs. −0.064) and head circumference (−0.782 vs. −0.157) (both outcomes P < 0.0001). Young, mixed-race women were most likely to be both smoking and using cannabis during pregnancy and their infants had a lower birthweight mean z score (−0.989 vs. −0.587, P = 0.028) and head circumference z score (−1.33 vs. 0.782, P = 0.025) than cigarette use alone.ConclusionYoung, mixed-race women were most likely to be both smoking and using cannabis during pregnancy and should be targeted for cessation programmes.
