Meta-Analysis Review
BACKGROUND
Supplementary oxygen is routinely administered to low-risk pregnant women during an elective caesarean section under regional anaesthesia; however, maternal and foetal outcomes have not been well established. This is an update of a review first published in 2013.
OBJECTIVES
The primary objective was to determine whether supplementary oxygen given to low-risk term pregnant women undergoing elective caesarean section under regional anaesthesia can prevent maternal and neonatal desaturation. The secondary objective was to compare the mean values of maternal and neonatal blood gas levels between mothers who received supplementary oxygen and those who did not (control group).
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, issue 11), MEDLINE (1948 to November 2014) and EMBASE (1980 to November 2014). The original search was first performed in February 2012. We reran the search in CENTRAL, MEDLINE, EMBASE in February 2016. One potential new study of interest was added to the list of 'Studies awaiting Classification' and will be incorporated into the formal review findings during the next review update.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) of low-risk pregnant women undergoing an elective caesarean section under regional anaesthesia and compared outcomes with, and without, oxygen supplementation.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted data, assessed methodological quality and performed subgroup and sensitivity analyses.
MAIN RESULTS
We found one new included study in this updated version. In total, our updated review includes 11 trials (with 753 participants). The low quality of evidence showed no significant differences in average Apgar scores at one minute (N = six trials, 519 participants; 95% confidence (CI) -0.16 to 0.31, P = 0.53) and at five minutes (N = six trials, 519 participants; 95% CI -0.06 to 0.06, P = 0.98). None of the 11 trials reported maternal desaturation. The very low quality of evidence showed that in comparison to room air, women in labour receiving supplementary oxygen had higher maternal oxygen saturation (N = three trials, 209 participants), maternal PaO2 (oxygen pressure in the blood; N = six trials, 241 participants), UaPO2 (foetal umbilical arterial blood; N = eight trials, 504 participants; 95% CI 1.8 to 4.9, P < 0.0001) and UvPO2 (foetal umbilical venous blood; N = 10 trials, 683 participants). There was high heterogeneity among these outcomes. A subgroup analysis showed no significant difference in UaPO2 between the two intervention groups in low-risk studies, whereas the high-risk studies showed a benefit for the neonatal oxygen group.
AUTHORS' CONCLUSIONS
Overall, we found no convincing evidence that giving supplementary oxygen to healthy term pregnant women during elective caesarean section under regional anaesthesia is either beneficial or harmful for either the mother or the foetus' short-term clinical outcome as assessed by Apgar scores. Although, there were significant higher maternal and neonatal blood gas values and markers of free radicals when extra oxygen was given, the results should be interpreted with caution due to the low grade quality of the evidence.

BACKGROUND
The 5-minute APGAR score is clinically used as a screening tool to assess how the newborn has reacted to previous care, remaining relevant for predicting neonatal survival. This study aimed to analyze the determinants of the 5th minute APGAR score, and the factors associated with the death and survival of newborns with low APGAR scores hospitalized in the neonatal intensive care unit (NICU) at a referral public hospital in North Brazil.
METHODS
This was a hospital-based retrospective case-control study with 277 medical records. Newborns who presented with a 1-minute APGAR score < 7 followed by a 5-minute APGAR score < 7 were considered cases, while a score ≥ 7 was categorized as controls. Univariate and multivariable logistic regression analyses were used to establish the determinant factors of the low APGAR score and death outcome in this group. Survival curves were obtained using the Kaplan-Meier estimator, and then univariate and multivariate Cox regression was performed.
RESULTS
After adjusted analysis, the factor associated with low APGAR scores was vaginal delivery (OR = 3.25, 95%CI = 1.60-6.62, p = 0.001). Birth injury (OR = 0.39, 95%CI = 0.19-0.83, p = 0.014) was associated with upper APGAR scores. No significant independent associations were observed between the variables analyzed and death in the low APGAR score group. The Kaplan-Meier curve showed that individuals who presented Cesarean delivery had a shorter survival time in the ICU.
CONCLUSION
In this setting, a 5-minute Apgar score < 7 was associated with the occurrence of vaginal delivery and birth injury with a 5-minute Apgar score ≥ 7. Survival in ICU was lower in newborns that were delivered via cesarean section.

Observational Study
INTRODUCTION
To understand and report the prevalence of meconium aspiration syndrome and the clinico-radiological features in a tertiary care hospital of western Nepal.
METHODS
An observational study carried out for a year in 2014-15 in all babies with MAS. Clinical and radiological profiles of MAS in relation to gender, gestational age, mode of delivery, birth weight, Apgar score, thickness of meconium, age at admission and the immediate outcome were studied.
RESULTS
Out of 584 admitted newborns (male=389; female=186) during the study period, 78 (13.4%) had meconium aspiration syndrome with male: female ratio of 1.2:1. Majority of babies admitted to NICU had thick meconium [n=52 (66.7%)]. There was no statistical significant difference in various parameters such as Apgar score at 1 and 5 minutes, respiratory distress, birth asphyxia, duration of oxygen use, MAS severity and chest x-ray in those with thick MAS compared to thin. Among all newborns with MAS, 59% (n=46) had abnormal radiological findings with over two-folds in those with thick MAS (71.7%)] compared to thin (28%). Hyperinflation (47.8%), diffuse patchy infiltration (37%), consolidation (21.7%) collapse (8.7%), right lung fissure (6.5%) and pneumothorax (8.7%) were the abnormal radiological findings seen in MAS babies. The odds of having APGAR score at 1 minute at least 7 or more was twice unlikely in those having thick meconium compared to thin (P=0.02) Conclusions: Thick meconium is relatively common with more significant abnormal radiological findings and low Apgar score.

INTRODUCTION
Labour is the process where uterine contractions lead to expulsion of product of conception through the vagina into the outer world. Labour pain is one of the most severe pains which has ever been evaluated and its fear is one of the reasons women wouldn't go for natural delivery. Delivery is a painful experience for all of the women except a few of them. The labor pain results from some physiological-psychological causes. Different pharmacological and non-pharmacological methods have been tried for pain relief in labour. The objective of this study is to see the effect of butorphanol injection in labour pain.
METHODS
It is a descriptive cross-sectional study conducted in B.P. Koirala institute of health sciences. We observed 200 pregnant women meeting the inclusion criteria and giving the informed consent who were on 1 mg butorphanol i.m. at the onset of active stage of labour every 4 hourly and on demand. Pain assessment was done by Numerical Pain analogue scale measured from 1 to 10. Fetal heart rate monitoring was done according to the hospital protocol. Caesarean section was performed for obstetrical indication. Neonatal outcome was evaluated by on duty pediatrician and APGAR score were noted at 1 and 5 min.
RESULTS
The pain scores in first, second, third, fourth hour were (8.83±0.773), (9.84±0.544), (9.94±0.338), (9.6±0.298) respectively, where 1st and 2nd hour is statistically significant.
CONCLUSIONS
Butorphanol is an effective labour analgesia without significant adverse effects on women and the neonatal outcome.

Meta-Analysis Review
Previous results are inconsistent regarding the association between maternal obesity and Apgar score or cord pH in humans. The aim of this study was to investigate the association between maternal pre-pregnancy and pregnancy body mass index (BMI) and infant Apgar score or cord pH. We conducted a systematic review of studies published in English before 20 August 2015 using PubMed, EMBASE, and Cochrane Library. Eleven cohort studies with a total of 2,586,265 participants finally met our inclusion criteria. Pooled results revealed the following factors associated with Apgar score <7 at 5 minutes: overweight (odds ratio [OR] 1.13; 95% confidence interval [CI], 1.08-1.20), obese (OR 1.40; 95% CI, 1.27-1.54), and very obese (OR 1.71; 95% CI, 1.55-1.89). The pooled analysis also revealed that maternal overweight or obesity increased the risk for Apgar score <7 at 1 minute. There was no association between maternal BMI and neonatal cord pH. Thus, this study suggests that maternal overweight and obesity affect baby's condition immediately after birth in general. More studies are needed to confirm these results and detect the influence of variables across studies.

INTRODUCTION
The Apgar score is routinely given at childbirth worldwide. A low Apgar score at 5 minutes is a strong predictor for neonatal death. Scores below 7 have been associated with higher risks of later neurologic disability. Few studies have assessed the association between Apgar score and school performance and intelligence. The existing literature points towards a possible association between Apgar score and later cognitive function, but the contradictions call for further investigation to fully understand the potential association. This study aimed to examine the possible association between Apgar score at 5 minutes and academic performance and intelligence in youth.
MATERIAL AND METHODS
The study is a cohort study. The cohort consists of all Danish liveborn children in 1978-2000 (n = 1 450 681). Data regarding pregnancies, births, parents, school grades, and intelligence of the children were retrieved from different Danish registers. Multiple imputations were performed to avoid discarding data. After exclusion, the final cohort consisted of 1 005 241 children. Associations between Apgar score at 5 minutes and school graduation, grades and attendance, and intelligence scores from conscription were analyzed using univariate and multivariate logistic and linear regressions.
RESULTS
No association was found between Apgar score and graduating primary school. Adjusted odds ratio (aOR) of graduating upper secondary education and attending conscription were significantly lower for children with scores below 7 compared with 7-10: graduating upper secondary education: Apgar 0-3: aOR 0.79 (95% CI 0.67-0.93), Apgar 4-6: aOR 0.86 (95% CI 0.81-0.93), attending conscription: Apgar 0-3: aOR 0.73 (95% CI 0.59-0.91), Apgar 4-6: aOR 0.73 (95% CI 0.66-0.80). The Apgar 4-6 group had significantly lower total mean primary school grade average: -0.13 (95% CI -0.21 to -0.054) and lower mean intelligence scores at conscription: -0.57 (95% CI -1.09 to -0.058). All other differences remained insignificant.
CONCLUSIONS
Performances when graduating school and attending conscription were overall equal regardless of Apgar score at 5 minutes. Chances of graduating primary school were the same irrespective of the score, but chances of graduating upper secondary education and attending conscription were significantly lower with scores below 7. The results suggest that children with scores below 7 may fail to appear at upper secondary education and conscription, but if they do, they perform equally to anyone else.

BACKGROUND
Birth asphyxia is a consistent key contributor to neonatal morbidity and mortality, notably in sub-Saharan Africa. The APGAR score, though a globally used diagnostic tool for birth asphyxia, remains largely understudied especially in resource-poor settings.
OBJECTIVE
This study determined how effectively the APGAR score is used to diagnose birth asphyxia in comparison to the gold standard (umbilical cord blood pH <7 with neurologic involvement) at Moi Teaching and Referral Hospital (MTRH), and identified healthcare provider factors that affect ineffective use of the score.
METHODS
Using a quantitative cross-sectional hospital-based design, term babies born in MTRH who weighed ≥2500g were randomly and systematically sampled; and healthcare providers who assign APGAR scores were enrolled via a census. Umbilical cord blood was drawn at birth and at 5minutes for pH analysis. APGAR scores assigned by healthcare providers were recorded. Effective use of the APGAR score was determined by sensitivity, specificity, positive and negative predictive values. At a significance level of 0.05, multiple logistic regression analysis identified the independent provider-associated factors affecting ineffective use of the APGAR score.
RESULTS
We enrolled 102 babies, and 50 (49%) were females. Among the 64 healthcare providers recruited, 40 (63%) were female and the median age was 34.5years [IQR: 31.0, 37.0]. Assigned APGAR scores had a sensitivity of 71% and specificity of 89%, with positive and negative predictive values of 62% and 92% respectively. Healthcare provider factors associated with ineffective APGAR score use included: instrumental delivery (OR: 8.83 [95% CI: 0.79, 199]), lack of access to APGAR scoring charts (OR: 56.0 [95% CI: 12.9, 322.3]), and neonatal resuscitation (OR: 23.83 [95% CI: 6.72, 101.99]).
CONCLUSION
Assigned APGAR scores had low sensitivity and positive predictive values. Healthcare provider factors independently associated with ineffective APGAR scoring include; instrumental delivery, lack of access to APGAR scoring charts, and neonatal resuscitation.

BACKGROUND
Attention-deficit hyperactivity disorder (ADHD) affects around 1 in 20 children and is associated with life-long sequelae. Previous studies of the association between Apgar score and ADHD have reported inconsistent findings.
METHODS
Record linkage of maternity, prescribing and school pupil census databases was used to conduct a population e-cohort study of singleton children born in Scotland and attending school in Scotland at any point between 2009 and 2013. Binary logistic regression analysis was used to investigate the association between 5-min Apgar score and treated ADHD adjusting for sociodemographic and maternity confounders.
RESULTS
Of the 758,423 children, 7,292 (0.96%) received ADHD medication. The results suggested a potential dose-response relationship between Apgar score and treated ADHD independent of confounders. Referent to an Apgar score of 10, risk of treated ADHD was higher for scores of 0-3 (adjusted OR 1.76, 95% CI 1.32-2.34), 4-6 (adjusted OR 1.50, 95% CI 1.21-1.86) and even 7-9 (adjusted OR 1.26, 95% CI 1.18-1.36) which are traditionally considered within the normal range.
CONCLUSIONS
In addition to reinforcing the need to maximise Apgar score through good obstetric practice, the findings suggest that Apgar score may be useful in predicting future risk of ADHD and therefore facilitating early diagnosis and treatment.

Meta-Analysis
OBJECTIVES
Esophagectomy is the most effective treatment for oesophageal cancer, although the incidence of postoperative complications remains high. Severe major complications, such as intrathoracic anastomotic leakage, are costly and life-threatening to patients. Therefore, early identification of postoperative complications is essential. The surgical Apgar score (SAS) was introduced by Gawande and colleagues to predict major complications after oesophagectomy. Several studies were carried out with inconsistent results.
METHODS
PubMed, Embase, Web of Science, ClinicalTrials.gov and the Cochrane Library were searched for studies regarding SAS and oesophagectomy. Forest plots were generated using a random-effects model to investigate the actual predictive value of SAS in identifying major complications after oesophagectomy.
RESULTS
Nine retrospective cohort studies were finally identified from selected electronic databases. The meta-analysis demonstrated that SAS could forecast the incidence of postoperative complications (odds ratio = 1.82, 95% confidence interval: 1.43-2.33, P < 0.001). Subgroup analysis validated the predictive value of SAS whether as continuous or discrete variables. In addition, a meta-analysis of 4 studies demonstrated that SAS could predict the incidence of pulmonary complications (odds ratio = 2.32, 95% confidence interval: 1.61-3.36, P < 0.001). Significant heterogeneity but no publication bias was found.
CONCLUSIONS
Lower SAS scores could predict the incidence of major morbidities and pulmonary complications after oesophagectomy. Significant heterogeneity limits the reliability of the results, even if publication bias is not observed. More high-quality prospective research should be conducted to verify the findings.
