Abstract
OBJECTIVE To assess at 24 months corrected age (CA) the neurological, respiratory, and general health status of children born prematurely from 27+0 to 33+6 weeks' gestation who were treated in a first-in-human study with a new fully synthetic surfactant (CHF5633) enriched with SP-B and SP-C proteins. OUTCOME MEASURES Children were assessed using Bayley Scales of Infant Development (BSID), with a score below normal defined as BSID-II Mental Development Index score <70, or BSID-III cognitive composite score <85. In addition, a health status questionnaire was used to check for functional disability including respiratory problems and related treatments, sensory and neurodevelopment assessments, communication skills as well as the number of hospitalizations. RESULTS 35 of 39 survivors had a neurodevelopmental assessment, 24 infants being evaluated by Bayley's Scales and 11 by health status questionnaires only. 23 children had scores within normal limits and one had BSID-III <85. The remaining 11 were judged clinically to have normal development. Health status questionnaires detected only issues that would normally be expected in preterm-born children. CONCLUSIONS This assessment offers reassurance that treatment with CHF5633 surfactant was not associated with adverse neurodevelopmental, respiratory, or health outcomes by two years corrected age.

Abstract
BACKGROUND Observational data suggest that slowly advancing enteral feeds in preterm infants may reduce necrotising enterocolitis but increase late-onset sepsis. The Speed of Increasing milk Feeds Trial (SIFT) compared two rates of feed advancement. OBJECTIVE To determine if faster (30 ml/kg/day) or slower (18 ml/kg/day) daily feed increments improve survival without moderate or severe disability and other morbidities in very preterm or very low-birthweight infants. DESIGN This was a multicentre, two-arm, parallel-group, randomised controlled trial. Randomisation was via a web-hosted minimisation algorithm. It was not possible to safely and completely blind caregivers and parents. SETTING The setting was 55 UK neonatal units, from May 2013 to June 2015. PARTICIPANTS The participants were infants born at < 32 weeks' gestation or a weight of < 1500 g, who were receiving < 30 ml/kg/day of milk at trial enrolment. INTERVENTIONS When clinicians were ready to start advancing feed volumes, the infant was randomised to receive daily feed increments of either 30 ml/kg/day or 18 ml/kg/day. In total, 1400 infants were allocated to fast feeds and 1404 infants were allocated to slow feeds. MAIN OUTCOME MEASURES The primary outcome was survival without moderate or severe neurodevelopmental disability at 24 months of age, corrected for gestational age. The secondary outcomes were mortality; moderate or severe neurodevelopmental disability at 24 months corrected for gestational age; death before discharge home; microbiologically confirmed or clinically suspected late-onset sepsis; necrotising enterocolitis (Bell's stage 2 or 3); time taken to reach full milk feeds (tolerating 150 ml/kg/day for 3 consecutive days); growth from birth to discharge; duration of parenteral feeding; time in intensive care; duration of hospital stay; diagnosis of cerebral palsy by a doctor or other health professional; and individual components of the definition of moderate or severe neurodevelopmental disability. RESULTS The results showed that survival without moderate or severe neurodevelopmental disability at 24 months occurred in 802 out of 1224 (65.5%) infants allocated to faster increments and 848 out of 1246 (68.1%) infants allocated to slower increments (adjusted risk ratio 0.96, 95% confidence interval 0.92 to 1.01). There was no significant difference between groups in the risk of the individual components of the primary outcome or in the important hospital outcomes: late-onset sepsis (adjusted risk ratio 0.96, 95% confidence interval 0.86 to 1.07) or necrotising enterocolitis (adjusted risk ratio 0.88, 95% confidence interval 0.68 to 1.16). Cost-consequence analysis showed that the faster feed increment rate was less costly but also less effective than the slower rate in terms of achieving the primary outcome, so was therefore found to not be cost-effective. Four unexpected serious adverse events were reported, two in each group. None was assessed as being causally related to the intervention. LIMITATIONS The study could not be blinded, so care may have been affected by knowledge of allocation. Although well powered for comparisons of all infants, subgroup comparisons were underpowered. CONCLUSIONS No clear advantage was identified for the important outcomes in very preterm or very low-birthweight infants when milk feeds were advanced in daily volume increments of 30 ml/kg/day or 18 ml/kg/day. In terms of future work, the interaction of different milk types with increments merits further examination, as may different increments in infants at the extremes of gestation or birthweight.

Abstract
BACKGROUND Observational data have shown that slow advancement of enteral feeding volumes in preterm infants is associated with a reduced risk of necrotizing enterocolitis but an increased risk of late-onset sepsis. However, data from randomized trials are limited. METHODS We randomly assigned very preterm or very-low-birth-weight infants to daily milk increments of 30 ml per kilogram of body weight (faster increment) or 18 ml per kilogram (slower increment) until reaching full feeding volumes. The primary outcome was survival without moderate or severe neurodevelopmental disability at 24 months. Secondary outcomes included components of the primary outcome, confirmed or suspected late-onset sepsis, necrotizing enterocolitis, and cerebral palsy. RESULTS Among 2804 infants who underwent randomization, the primary outcome could be assessed in 1224 (87.4%) assigned to the faster increment and 1246 (88.7%) assigned to the slower increment. Survival without moderate or severe neurodevelopmental disability at 24 months occurred in 802 of 1224 infants (65.5%) assigned to the faster increment and 848 of 1246 (68.1%) assigned to the slower increment (adjusted risk ratio, 0.96; 95% confidence interval [CI], 0.92 to 1.01; P = 0.16). Late-onset sepsis occurred in 414 of 1389 infants (29.8%) in the faster-increment group and 434 of 1397 (31.1%) in the slower-increment group (adjusted risk ratio, 0.96; 95% CI, 0.86 to 1.07). Necrotizing enterocolitis occurred in 70 of 1394 infants (5.0%) in the faster-increment group and 78 of 1399 (5.6%) in the slower-increment group (adjusted risk ratio, 0.88; 95% CI, 0.68 to 1.16). CONCLUSIONS There was no significant difference in survival without moderate or severe neurodevelopmental disability at 24 months in very preterm or very-low-birth-weight infants with a strategy of advancing milk feeding volumes in daily increments of 30 ml per kilogram as compared with 18 ml per kilogram.

Abstract
OBJECTIVE The aim of this study was to estimate the incidence of anaphylaxis in pregnancy and describe the management and outcomes in the UK. DESIGN A population-based descriptive study using the UK Obstetric Surveillance System (UKOSS). SETTING All consultant-led maternity units in the UK. POPULATION All pregnant women who had anaphylaxis between 1 October 2012 and 30 September 2015. Anaphylaxis was defined as a severe, life-threatening generalised or systemic hypersensitivity reaction. METHODS Prospective case notification using UKOSS. MAIN OUTCOME MEASURES Maternal mortality, severe maternal morbidity, neonatal mortality and severe neonatal morbidity. RESULTS There were 37 confirmed cases of anaphylaxis in pregnancy, giving an estimated incidence of 1.6 (95% CI: 1.1-2.2) per 100 000 maternities. Four cases of anaphylaxis were in women with known penicillin allergies: two received co-amoxiclav and two cephalosporins. Twelve women had anaphylaxis following prophylactic use of antibiotics at the time of a caesarean delivery. Prophylactic use of antibiotics for Group B streptococcal infection accounted for anaphylaxis in one woman. Two women died (5%), 14 (38%) women were admitted to intensive care and seven women (19%) had one or more additional severe maternal morbidities, which included three haemorrhagic events, two cardiac arrests, one thrombotic event and one pneumonia. No infants died; however, in those infants whose mother had anaphylaxis before delivery (n = 18) there were seven (41%) neonatal intensive care unit admissions, three preterm births and one baby was cooled for neonatal encephalopathy. CONCLUSIONS Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration. This study highlights the seriousness of the outcomes of this condition for the mother. The low incidence is reassuring given the large proportion of the pregnant population that receive prophylactic antibiotics during delivery. TWEETABLE ABSTRACT Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration.

Abstract
IMPORTANCE There are potential benefits and harms of hyperoxemia and hypoxemia for extremely preterm infants receiving more vs less supplemental oxygen. OBJECTIVE To compare the effects of different target ranges for oxygen saturation as measured by pulse oximetry (Spo2) on death or major morbidity. DESIGN, SETTING, AND PARTICIPANTS Prospectively planned meta-analysis of individual participant data from 5 randomized clinical trials (conducted from 2005-2014) enrolling infants born before 28 weeks' gestation. EXPOSURES Spo2 target range that was lower (85%-89%) vs higher (91%-95%). MAIN OUTCOMES AND MEASURES The primary outcome was a composite of death or major disability (bilateral blindness, deafness, cerebral palsy diagnosed as ≥2 level on the Gross Motor Function Classification System, or Bayley-III cognitive or language score <85) at a corrected age of 18 to 24 months. There were 16 secondary outcomes including the components of the primary outcome and other major morbidities. RESULTS A total of 4965 infants were randomized (2480 to the lower Spo2 target range and 2485 to the higher Spo2 range) and had a median gestational age of 26 weeks (interquartile range, 25-27 weeks) and a mean birth weight of 832 g (SD, 190 g). The primary outcome occurred in 1191 of 2228 infants (53.5%) in the lower Spo2 target group and 1150 of 2229 infants (51.6%) in the higher Spo2 target group (risk difference, 1.7% [95% CI, -1.3% to 4.6%]; relative risk [RR], 1.04 [95% CI, 0.98 to 1.09], P = .21). Of the 16 secondary outcomes, 11 were null, 2 significantly favored the lower Spo2 target group, and 3 significantly favored the higher Spo2 target group. Death occurred in 484 of 2433 infants (19.9%) in the lower Spo2 target group and 418 of 2440 infants (17.1%) in the higher Spo2 target group (risk difference, 2.8% [95% CI, 0.6% to 5.0%]; RR, 1.17 [95% CI, 1.04 to 1.31], P = .01). Treatment for retinopathy of prematurity was administered to 220 of 2020 infants (10.9%) in the lower Spo2 target group and 308 of 2065 infants (14.9%) in the higher Spo2 target group (risk difference, -4.0% [95% CI, -6.1% to -2.0%]; RR, 0.74 [95% CI, 0.63 to 0.86], P < .001). Severe necrotizing enterocolitis occurred in 227 of 2464 infants (9.2%) in the lower Spo2 target group and 170 of 2465 infants (6.9%) in the higher Spo2 target group (risk difference, 2.3% [95% CI, 0.8% to 3.8%]; RR, 1.33 [95% CI, 1.10 to 1.61], P = .003). CONCLUSIONS AND RELEVANCE In this prospectively planned meta-analysis of individual participant data from extremely preterm infants, there was no significant difference between a lower Spo2 target range compared with a higher Spo2 target range on the primary composite outcome of death or major disability at a corrected age of 18 to 24 months. The lower Spo2 target range was associated with a higher risk of death and necrotizing enterocolitis, but a lower risk of retinopathy of prematurity treatment.

Abstract
BACKGROUND Metformin is widely used to treat gestational diabetes (GDM), but many women remain hyperglycaemic and require additional therapy. We aimed to determine recruitment rate and participant throughput in a randomised trial of glibenclamide compared with standard therapy insulin (added to maximum tolerated metformin) for treatment of GDM. METHODS We conducted an open label feasibility study in 5 UK antenatal clinics among pregnant women 16 to 36 weeks' gestation with metformin-treated GDM. Women failing to achieve adequate glycaemic control on metformin monotherapy were randomised to additional glibenclamide or insulin. The primary outcome was recruitment rate. We explored feasibility with uptake, retention, adherence, safety, glycaemic control, participant satisfaction and clinical outcomes. RESULTS Records of 197 women were screened and 23 women randomised to metformin and glibenclamide (n = 13) or metformin and insulin (n = 10). Mean (SD) recruitment rate was 0.39 (0.62) women/centre/month. 9/13 (69.2%, 95%CI 38.6-90.9%) women adhered to glibenclamide and all provided outcome data (100% retention). There were no episodes of severe hypoglycaemia, but metformin and insulin gave superior glycaemic control to metformin and glibenclamide, with fewer blood glucose readings <3.5 mmol/l (median [IQR] difference/woman/week of treatment 0.58 [0.03-1.87]). CONCLUSIONS A large randomised controlled trial comparing glibenclamide or insulin in combination with metformin for women with GDM would be feasible but is unlikely to be worthwhile, given the poorer glycaemic control with glibenclamide and metformin in this pilot study. The combination of metformin and glibenclamide should be reserved for women with GDM with true needle phobia or inability to use insulin therapy.

Abstract
BACKGROUND The use of supplemental oxygen in the care of extremely preterm infants has been common practice since the 1940s. Despite this, there is little agreement regarding which oxygen saturation (SpO₂) ranges to target to maximise short- or long-term growth and development, while minimising harms. There are two opposing concerns. Lower oxygen levels (targeting SpO₂ at 90% or less) may impair neurodevelopment or result in death. Higher oxygen levels (targeting SpO₂ greater than 90%) may increase severe retinopathy of prematurity or chronic lung disease.The use of pulse oximetry to non-invasively assess neonatal SpO₂ levels has been widespread since the 1990s. Until recently there were no randomised controlled trials (RCTs) that had assessed whether it is better to target higher or lower oxygen saturation levels in extremely preterm infants, from birth or soon thereafter. As a result, there is significant international practice variation and uncertainty remains as to the most appropriate range to target oxygen saturation levels in preterm and low birth weight infants. OBJECTIVES 1. What are the effects of targeting lower versus higher oxygen saturation ranges on death or major neonatal and infant morbidities, or both, in extremely preterm infants?2. Do these effects differ in different types of infants, including those born at a very early gestational age, or in those who are outborn, without antenatal corticosteroid coverage, of male sex, small for gestational age or of multiple birth, or by mode of delivery? SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 4), MEDLINE via PubMed (1966 to 11 April 2016), Embase (1980 to 11 April 2016) and CINAHL (1982 to 11 April 2016). We also searched clinical trials databases, conference proceedings and the reference lists of retrieved articles for randomised controlled trials. SELECTION CRITERIA Randomised controlled trials that enrolled babies born at less than 28 weeks' gestation, at birth or soon thereafter, and targeted SpO₂ ranges of either 90% or below or above 90% via pulse oximetry, with the intention of maintaining such targets for at least the first two weeks of life. DATA COLLECTION AND ANALYSIS We used the standard methods of Cochrane Neonatal to extract data from the published reports of the included studies. We sought some additional aggregate data from the original investigators in order to align the definitions of two key outcomes. We conducted the meta-analyses with Review Manager 5 software, using the Mantel-Haenszel method for estimates of typical risk ratio (RR) and risk difference (RD) and a fixed-effect model. We assessed the included studies using the Cochrane 'Risk of bias' and GRADE criteria in order to establish the quality of the evidence. We investigated heterogeneity of effects via pre-specified subgroup and sensitivity analyses. MAIN RESULTS Five trials, which together enrolled 4965 infants, were eligible for inclusion. The investigators of these five trials had prospectively planned to combine their data as part of the NeOProM (Neonatal Oxygen Prospective Meta-analysis) Collaboration. We graded the quality of evidence as high for the key outcomes of death, major disability, the composite of death or major disability, and necrotising enterocolitis; and as moderate for blindness and retinopathy of prematurity requiring treatment.When an aligned definition of major disability was used, there was no significant difference in the composite primary outcome of death or major disability in extremely preterm infants when targeting a lower (SpO₂ 85% to 89%) versus a higher (SpO₂ 91% to 95%) oxygen saturation range (typical RR 1.04, 95% confidence interval (CI) 0.98 to 1.10; typical RD 0.02, 95% CI -0.01 to 0.05; 5 trials, 4754 infants) (high-quality evidence). Compared with a higher target range, a lower target range significantly increased the incidence of death at 18 to 24 months corrected age (typical RR 1.16, 95% CI 1.03 to 1.31; typical RD 0.03, 95% CI 0.01 to 0.05; 5 trials, 4873 infants) (high-quality evidence) and necrotising enterocolitis (typical RR 1.24, 95% 1.05 to 1.47; typical RD 0.02, 95% CI 0.01 to 0.04; 5 trials, 4929 infants; I² = 0%) (high-quality evidence). Targeting the lower range significantly decreased the incidence of retinopathy of prematurity requiring treatment (typical RR 0.72, 95% CI 0.61 to 0.85; typical RD -0.04, 95% CI -0.06 to -0.02; 5 trials, 4089 infants; I² = 69%) (moderate-quality evidence). There were no significant differences between the two treatment groups for major disability including blindness, severe hearing loss, cerebral palsy, or other important neonatal morbidities.A subgroup analysis of major outcomes by type of oximeter calibration software (original versus revised) found a significant difference in the treatment effect between the two software types for death (interaction P = 0.03), with a significantly larger treatment effect seen for those infants using the revised algorithm (typical RR 1.38, 95% CI 1.13 to 1.68; typical RD 0.06, 95% CI 0.01 to 0.10; 3 trials, 1716 infants). There were no other important differences in treatment effect shown by the subgroup analyses using the currently available data. AUTHORS' CONCLUSIONS In extremely preterm infants, targeting lower (85% to 89%) SpO₂ compared to higher (91% to 95%) SpO₂ had no significant effect on the composite outcome of death or major disability or on major disability alone, including blindness, but increased the average risk of mortality by 28 per 1000 infants treated. The trade-offs between the benefits and harms of the different oxygen saturation target ranges may need to be assessed within local settings (e.g. alarm limit settings, staffing, baseline outcome risks) when deciding on oxygen saturation targeting policies.

Abstract
Background In the UK, 1–2% of infants are born very preterm (<32 weeks of gestation) or have very low birth weight (<1500 g). Very preterm infants are initially unable to be fed nutritional volumes of milk and therefore require intravenous nutrition. Milk feeding strategies influence several long and short term health outcomes including growth, survival, infection (associated with intravenous nutrition) and necrotising enterocolitis (NEC); with both infection and NEC being key predictive factors of long term disability. Currently there is no consistent strategy for feeding preterm infants across the UK. The SIFT trial will test two speeds of increasing milk feeds with the primary aim of determining effects on survival without moderate or severe neurodevelopmental disability at 24 months of age, corrected for prematurity. The trial will also examine many secondary outcomes including infection, NEC, time taken to reach full feeds and growth. Methods/design Two thousand eight hundred very preterm or very low birth weight infants will be recruited from approximately 30 hospitals across the UK to a randomised controlled trial. Infants with severe congenital anomaly or no realistic chance of survival will be excluded. Infants will be randomly allocated to either a faster (30 ml/kg/day) or slower (18 ml/kg/day) rate of increase in milk feeds. Data will be collected during the neonatal hospital stay on weight, infection rates, episodes of NEC, length of stay and time to reach full milk feeds. Long term health outcomes comprising vision, hearing, motor and cognitive impairment will be assessed at 24 months of age (corrected for prematurity) using a parent report questionnaire. Discussion Extensive searches have found no active or proposed studies investigating the rate of increasing milk feeds. The results of this trial will have importance for optimising incremental milk feeding for very preterm and/or very low birth weight infants. No additional resources will be required to implement an optimal feeding strategy, and therefore if successful, the trial results could rapidly be adopted across the NHS at low cost.

Abstract
AIM This study determined current international clinical practice and opinions regarding initial fractional inspired oxygen (FiO2 ) and pulse oximetry (SpO2 ) targets for delivery room resuscitation of preterm infants of less than 29 weeks of gestation. METHODS An online survey was disseminated to neonatal clinicians via established professional clinical networks using a web-based survey programme between March 9 and June 30, 2015. RESULTS Of the 630 responses from 25 countries, 60% were from neonatologists. The majority (77%) would target SpO2 between the 10th to 50th percentiles values for full-term infants. The median starting FiO2 was 0.3, with Japan using the highest (0.4) and the UK using the lowest (0.21). New Zealand targeted the highest SpO2 percentiles (median 50%). Most respondents agreed or did not disagree that a trial was required that compared the higher FiO2 of 0.6 (83%), targeting the 50th SpO2 percentile (60%), and the lower FiO2 of 0.21 (80%), targeting the 10th SpO2 percentile (78%). Most (65%) would join this trial. Many considered that evidence was lacking and further research was needed. CONCLUSION Clinicians currently favour lower SpO2 targets for preterm resuscitation, despite acknowledging the lack of evidence for benefit or harm, and 65% would join a clinical trial.

Abstract
BACKGROUND The safest ranges of oxygen saturation in preterm infants have been the subject of debate. METHODS In two trials, conducted in Australia and the United Kingdom, infants born before 28 weeks' gestation were randomly assigned to either a lower (85 to 89%) or a higher (91 to 95%) oxygen-saturation range. During enrollment, the oximeters were revised to correct a calibration-algorithm artifact. The primary outcome was death or disability at a corrected gestational age of 2 years; this outcome was evaluated among infants whose oxygen saturation was measured with any study oximeter in the Australian trial and those whose oxygen saturation was measured with a revised oximeter in the U.K. trial. RESULTS After 1135 infants in Australia and 973 infants in the United Kingdom had been enrolled in the trial, an interim analysis showed increased mortality at a corrected gestational age of 36 weeks, and enrollment was stopped. Death or disability in the Australian trial (with all oximeters included) occurred in 247 of 549 infants (45.0%) in the lower-target group versus 217 of 545 infants (39.8%) in the higher-target group (adjusted relative risk, 1.12; 95% confidence interval [CI], 0.98 to 1.27; P=0.10); death or disability in the U.K. trial (with only revised oximeters included) occurred in 185 of 366 infants (50.5%) in the lower-target group versus 164 of 357 infants (45.9%) in the higher-target group (adjusted relative risk, 1.10; 95% CI, 0.97 to 1.24; P=0.15). In post hoc combined, unadjusted analyses that included all oximeters, death or disability occurred in 492 of 1022 infants (48.1%) in the lower-target group versus 437 of 1013 infants (43.1%) in the higher-target group (relative risk, 1.11; 95% CI, 1.01 to 1.23; P=0.02), and death occurred in 222 of 1045 infants (21.2%) in the lower-target group versus 185 of 1045 infants (17.7%) in the higher-target group (relative risk, 1.20; 95% CI, 1.01 to 1.43; P=0.04). In the group in which revised oximeters were used, death or disability occurred in 287 of 580 infants (49.5%) in the lower-target group versus 248 of 563 infants (44.0%) in the higher-target group (relative risk, 1.12; 95% CI, 0.99 to 1.27; P=0.07), and death occurred in 144 of 587 infants (24.5%) versus 99 of 586 infants (16.9%) (relative risk, 1.45; 95% CI, 1.16 to 1.82; P=0.001). CONCLUSIONS Use of an oxygen-saturation target range of 85 to 89% versus 91 to 95% resulted in nonsignificantly higher rates of death or disability at 2 years in each trial but in significantly increased risks of this combined outcome and of death alone in post hoc combined analyses.

Abstract
BACKGROUND Neonatal sepsis is a major cause of death and complications despite antibiotic treatment. Effective adjunctive treatments are needed. Newborn infants are relatively deficient in endogenous immunoglobulin. Meta-analyses of trials of intravenous immune globulin for suspected or proven neonatal sepsis suggest a reduced rate of death from any cause, but the trials have been small and have varied in quality. METHODS At 113 hospitals in nine countries, we enrolled 3493 infants receiving antibiotics for suspected or proven serious infection and randomly assigned them to receive two infusions of either polyvalent IgG immune globulin (at a dose of 500 mg per kilogram of body weight) or matching placebo 48 hours apart. The primary outcome was death or major disability at the age of 2 years. RESULTS There was no significant between-group difference in the rates of the primary outcome, which occurred in 686 of 1759 infants (39.0%) who received intravenous immune globulin and in 677 of 1734 infants (39.0%) who received placebo (relative risk, 1.00; 95% confidence interval, 0.92 to 1.08). Similarly, there were no significant differences in the rates of secondary outcomes, including the incidence of subsequent sepsis episodes. In follow-up of 2-year-old infants, there were no significant differences in the rates of major or nonmajor disability or of adverse events. CONCLUSIONS Therapy with intravenous immune globulin had no effect on the outcomes of suspected or proven neonatal sepsis.

Abstract
Early neonatal biochemical values are generally considered to reflect maternal values. However, studies have been inconclusive due to the statistical methods used. We hypothesized that there would not be important differences in plasma biochemistry between newborn twins, suggesting a common mechanism of control, and that differences between unrelated infant pairs would be greater. All twins over a 5-year period who had plasma biochemistry measured within 6 hours of birth were identified retrospectively. An unrelated control infant was matched to one of each twin pair. The 95% limits of agreement for plasma urea, creatinine, and sodium were calculated for twin pairs and unrelated matched infant pairs. Fifty-three twin pairs were studied. For urea, creatinine, and sodium, 95% of differences between twins were less than or equal to 1.5 mmol/L (8.9 mg/dL), 9.2 μmol/L (0.1 mg/dL), and 5.1 mmol/L (11.7 mg/dL), respectively. In unrelated infant pairs, the corresponding values were 4.0 mmol/L (24.3 mg/dL), 33.9 μmol/L (0.4 mg/dL), and 8.2 mmol/L (18.9 mg/dL). Differences between unrelated infant pairs were significantly wider than differences between twins ( p < 0.001). This study has demonstrated a close and significant agreement in urea, sodium, and creatinine when measured soon after birth in twin pairs compared with unrelated infants, implying a common mechanism of control.

Abstract
BACKGROUND Cord blood lactate at birth is a marker of antenatal hypoxia, and is comparable to pH as a prognostic tool. OBJECTIVE To determine, by a prospective observational study, the effect of delayed sampling from arteries and veins that were double clamped to isolate the blood from the placenta (clamped), and from vessels that were not isolated from the placenta (unclamped). METHODS Paired samples taken from clamped and unclamped vessels at 0, 20, 40, and 60 minutes were analysed for lactate, base excess, pH, and Pco(2). Data were analysed as the change from time 0 at 20, 40, and 60 minutes. RESULTS Thirty eight placentas of infants delivered by elective caesarean section were studied. Arterial samples were taken from 20 placentas, and venous samples from 18 placentas. Arterial and venous lactate was significantly higher than at time 0 by 20 minutes in both clamped and unclamped vessels. Changes in unclamped vessels were greater than in clamped vessels. The pH remained unchanged over 60 minutes in clamped vessels, but changed significantly in unclamped vessels. Base excess changed significantly in both clamped and unclamped vessels. CONCLUSIONS Cord blood samples taken after 20 minutes delay are unreliable for lactate measurement, even if the vessel has been doubly clamped to isolate the blood from the placenta. Current guidelines that state that blood can be sampled from a clamped cord for up to one hour after delivery should not apply to the interpretation of lactate or base excess. Delayed sampling from unclamped cords is very unreliable.

Abstract
Recent evidence suggests that inflammatory cytokines may play an important role in cerebral and pulmonary injury, especially in preterm infants. Immunomodulatory agents may help to limit such injury by reducing inflammation. Immunoglobulin has multiple anti-inflammatory properties and can modulate the inflammatory cytokine response. New evidence is required to test the hypotheses that prophylaxis or treatment with intravenous immunoglobulin may limit such inflammatory damage.

Abstract
OBJECTIVES The objective of this study was to assess the effectiveness of government regulation of private pharmacy practice in a low-income country. METHODS The intervention comprised inspections of the pharmacies, information, and distribution of documents to drug sellers and sanctions. It was implemented at two different intensity levels, active and regular intervention. The methods used to assess the effect of the interventions were interviews with the district drug inspectors, drug sellers and customers, inspection of drug purchases, and indicator surveys of pharmacies. Indicators for pharmacy-specific quality as well as for dispensing quality were developed. RESULTS The main finding was one of strong overall improvements from initially low levels. The improvements were particularly marked by increases in the availability of essential materials for dispensing by 34% and in order in the pharmacy by 19%. Information given to customers increased from 35% to 51% and the mixing of different drugs in the same package went down from 17% to 9%. The pharmacies in the active intervention districts showed greater improvements for four of the six indicators, although statistically significant compared with the regular intervention districts only for the essential materials indicator. CONCLUSIONS It was concluded that the regulatory activities have probably been an important factor behind the service quality improvements. It appeared feasible as well as effective to regulate private pharmacy practice in this particular low-income setting.

Abstract
AIM The aim was to study the practices of public and private pharmacies in the Savannakhet province, Lao PDR, in relation to defined aspects of good pharmacy practice (GPP) and rational use of drugs (RUD). STUDY DESIGN The study design was cross-sectional using structured interviews and observations. A total of 105 drug sellers (31% and 4% had pharmacy education at public and private pharmacies, respectively) were interviewed, and the pharmacies were inspected. In addition, 576 customers were interviewed immediately after the drug transaction and all their drug purchases were recorded. Facility, patient-care and prescribing indicators covering aspects of GPP and RUD were used to measure and compare the quality of services of the pharmacies. RESULTS The results showed that public pharmacies differed significantly from private pharmacies, with lower mean scores for availability of essential drugs (5.1 vs 6.4), 95% confidence interval (CI -2.23, -0.34) and essential materials (5.6 vs 6.9, 95% CI -2.40, -0.20), and with a higher percentage of antibiotics dispensed (34% vs 24%, P<0.02), as well as more injections (31% vs 7%, P < 0.001) and drugs per customer (2.4 vs 1.4, 95% CI 0.84, 1.16). More drug purchases were decided by health workers at public pharmacies than at private pharmacies (92% vs 16%). At public pharmacies, significantly more drugs were prescribed from the National Essential Drug List (76% vs 56%, P=0.004), and more drugs had an international non-proprietary name (67% vs 35%, P<0.001). There was no significant difference regarding order in the pharmacy, oral information and drugs adequately labelled at the public pharmacies compared with the private pharmacies. CONCLUSION In spite of the differences shown, both public and private pharmacies performed suboptimally in relation to several aspects of GPP and RUD. The lack of essential drugs, essential materials, information on drug use and adequate drug labelling all contribute to irrational use of drugs. Interventions are needed to improve practice and drug use.

Abstract
The private sector is a dominant actor in the provision of pharmaceuticals, particularly in developing countries. Private provision of drugs has been associated with risks regarding availability, affordability, rational use and drug quality. Ensuring an effective regulatory framework is therefore a major challenge for governments, yet the capacity of regulatory authorities is often outstripped by private sector growth. In the Lao People's Democratic Republic (Lao P.D.R.), a poor, landlocked country in South East Asia, the private provision of drugs has increased dramatically since the liberalisation of the economy in the late 1980s. This paper aims to describe the quality of the private pharmacy services in the Savannakhet province of Lao P.D.R. In order to do this, a monitoring instrument which serves to make the concept of Good Pharmacy Practice (GPP) operational was developed and applied to a sample of pharmacies. Service quality, as measured by three facility-specific indicators, showed a tendency to be lower in the most distant districts. Poor dispensing practices were manifest by a lack of information about drugs sold in 59% of cases, drugs not being labelled in 47% and different drugs being mixed in the same package in 26% of cases. The prices of four sample drugs were slightly higher in the remote districts. A 10-fold price difference for the same drug was recorded in one district. After reporting the findings, the paper discusses the possible influence of district and pharmacy variables on the quality of services, and goes on to discuss the price differences. It is concluded that further government interventions are needed in order to improve the quality of services and to focus regulatory action on a limited number of aspects, to ensure that drugs can be traced before trying to establish a comprehensive regulatory system.

Abstract
Pneumothorax in the newborn has a significant mortality and morbidity. Early diagnosis would be likely to improve the outlook. Forty-two consecutive cases of pneumothorax that developed after admission to a tertiary referral neonatal medical intensive care unit over 4 y from 1993 to 1996 were reviewed. The time of onset of the pneumothorax was determined by retrospective evaluation of the computerized trend of transcutaneous carbon dioxide (tcpCO2) and oxygen tensions. The timing of the occurrence in the notes and x-rays determined the time of clinical diagnosis noted at the time. The difference was the time the condition was undiagnosed. The overall mortality before discharge was 45% (19 cases), four patients succumbing within 2 h. The median time (range) between onset of pneumothorax and clinical diagnosis was 127 min (45-660 min). In most cases, the endotracheal tube was aspirated and the transcutaneous blood gas sensor was repositioned, and in at least 40% of the cases, the baby was reintubated before the diagnosis was made. Reference centiles were constructed for level of tcpCO2 and slope of the trended tcpCO2 over various time intervals (in minutes) from 729 infants from 23 to 42 wk gestation who needed intensive care during the first 7 d of life from the same time period. The 5-min tcpCO2 trend slopes were compared in index and matched control infants. The presence of five consecutive and overlapping 5-min slopes greater than the 90th centile showed good discrimination for a pneumothorax (area under the receiver operating characteristic curve, 89%). We concluded that 1) the clinical diagnosis of pneumothorax was late, occurring when infants decompensate; 2) trend monitoring of tcpCO2 might allow the diagnosis to be made earlier if used properly; and 3) use of reference centiles of the trended slopes of tcpCO2 might be used for automatic decision support in the future.

Abstract
An explosive development of private pharmacies in the Lao People's Democratic Republic (Lao P.D.R.) has led to 80% of pharmaceuticals being provided by the private sector. In order to achieve the goal of access to good quality health care for all citizens, the Lao government is making an effort to regulate the private pharmaceutical sector using the emerging legal system of laws, decrees, and regulations. The aim of this paper is to describe and analyze the system of drug regulation in Lao P.D.R. in relation to the public social goals. Relevant official documents at the central, provincial and district levels have been reviewed, interviews were held with 30 key informants and 15 pharmacies were surveyed. The public social goals have been expressed in terms of equity and quality of care. However, total drug expenditure may be as low as US$1 per person per year which is far below any minimum standard and does not make it possible to achieve reasonable access to drugs for all. The regulatory system has so far been focused on entry into the pharmaceutical retail market and dealing with basic issues of product quality and conditions of sale. An enforcement system including sanctions is being developed; other policy instruments such as information and economic means are hardly being used at all. The government presently faces a trade-off between quality of pharmaceutical services and geographical equity of access. The study shows that regulation is strongly influenced by the general socioeconomic context.

Abstract
OBJECTIVE Despite widespread recognition that prenatal administration of corticosteroids dramatically reduces perinatal mortality and morbidity, clinical practice in this area remains less than ideal. We therefore reviewed our practice to identify reasons for this and to determine attainable standards of care. DESIGN Retrospective case record review. SETTING Level three maternity unit in Edinburgh, UK. POPULATION All women admitted at gestations of 24 to 34 weeks and 6 days inclusive, and all women receiving corticosteroids in one institution, over a 10-month period. MAIN OUTCOME MEASURES The number and clinical features of women delivering before and after 35 weeks of pregnancy who had received corticosteroids. RESULTS Seven hundred and two women were admitted during the study period; case records were available for 688 of these. One hundred and ninety-two women (28%) delivered before 35 weeks of gestation, of whom 123 (64%) had received dexamethasone. Of 69 women who received no steroids 30 (43%) were in hospital for more than 24 hours before delivery. Overall, 29% of women receiving dexamethasone delivered after 35 weeks of gestation and 42 (24%) women treated with dexamethasone received more than one course. While the grade of admitting doctor did not affect prescribing, there were other significant differences that may help guide future practice. CONCLUSIONS This study provides some guidance for optimising corticosteroid prescribing and for the development of clinical practice guidelines. Approximately 80% of women should be able to receive at least some corticosteroids prior to delivery before 35 completed weeks of pregnancy.

Abstract
New actors on the international health scene have emerged, challenging WHO's leadership in global health. The role and functions of WHO have been questioned. Changes in financing have eroded the influence of the governing bodies. The Nordic countries, which together provide a considerable share of the total voluntary contributions to WHO, have recently made a number of studies of WHO, pinpointing weaknesses and proposing reforms. A slow reform process is also taking place within WHO. The main conclusions from these studies are analyzed and the areas with the greatest need for reform are studied. This paper presents proposals for the far-reaching reforms needed for WHO to recapture its leadership role in international health.
