Abstract
IMPORTANCE It has not been established whether noninvasive ventilation (NIV) reduces the need for invasive mechanical ventilation in patients who develop hypoxemic acute respiratory failure after abdominal surgery. OBJECTIVE To evaluate whether noninvasive ventilation improves outcomes among patients developing hypoxemic acute respiratory failure after abdominal surgery. DESIGN, SETTING, AND PARTICIPANTS Multicenter, randomized, parallel-group clinical trial conducted between May 2013 and September 2014 in 20 French intensive care units among 293 patients who had undergone abdominal surgery and developed hypoxemic respiratory failure (partial oxygen pressure <60 mm Hg or oxygen saturation [SpO2] ≤90% when breathing room air or <80 mm Hg when breathing 15 L/min of oxygen, plus either [1] a respiratory rate above 30/min or [2] clinical signs suggestive of intense respiratory muscle work and/or labored breathing) if it occurred within 7 days after surgical procedure. INTERVENTIONS Patients were randomly assigned to receive standard oxygen therapy (up to 15 L/min to maintain SpO2 of 94% or higher) (n = 145) or NIV delivered via facial mask (inspiratory pressure support level, 5-15 cm H2O; positive end-expiratory pressure, 5-10 cm H2O; fraction of inspired oxygen titrated to maintain SpO2 ≥94%) (n = 148). MAIN OUTCOMES AND MEASURES The primary outcome was tracheal reintubation for any cause within 7 days of randomization. Secondary outcomes were gas exchange, invasive ventilation-free days at day 30, health care-associated infections, and 90-day mortality. RESULTS Among the 293 patients (mean age, 63.4 [SD, 13.8] years; n=224 men) included in the intention-to-treat analysis, reintubation occurred in 49 of 148 (33.1%) in the NIV group and in 66 of 145 (45.5%) in the standard oxygen therapy group within+ 7 days after randomization (absolute difference, -12.4%; 95% CI, -23.5% to -1.3%; P = .03). Noninvasive ventilation was associated with significantly more invasive ventilation-free days compared with standard oxygen therapy (25.4 vs 23.2 days; absolute difference, -2.2 days; 95% CI, -0.1 to 4.6 days; P = .04), while fewer patients developed health care-associated infections (43/137 [31.4%] vs 63/128 [49.2%]; absolute difference, -17.8%; 95% CI, -30.2% to -5.4%; P = .003). At 90 days, 22 of 148 patients (14.9%) in the NIV group and 31 of 144 (21.5%) in the standard oxygen therapy group had died (absolute difference, -6.5%; 95% CI, -16.0% to 3.0%; P = .15). There were no significant differences in gas exchange. CONCLUSIONS AND RELEVANCE Among patients with hypoxemic respiratory failure following abdominal surgery, use of NIV compared with standard oxygen therapy reduced the risk of tracheal reintubation within 7 days. These findings support use of NIV in this setting. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01971892.

Abstract
BACKGROUND Transient tachypnoea of the newborn (TTN) results from delayed clearance of lung liquid and is a common cause of admission of full-term infants to neonatal intensive care units. The condition is particularly common after elective caesarean section. Conventional treatment involves appropriate oxygen administration and continuous positive airway pressure in some cases. Most infants receive antibiotic therapy. Hastening the clearance of lung liquid may shorten the duration of the symptoms and reduce complications. OBJECTIVES To determine whether diuretic administration reduces the duration of oxygen therapy and respiratory symptoms and shortens hospital stay in term infants presenting with transient tachypnoea of the newborn. SEARCH METHODS An updated search was carried out in September 2015 of the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library issue 9, 2015), MEDLINE via Ovid, EMBASE, PubMed, and CINAHL via OVID. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials that compared the effect of diuretics administration versus placebo or no treatment in infants of less than seven days of age, born at 37 or more weeks of gestation with the clinical picture of transient tachypnoea of the newborn. DATA COLLECTION AND ANALYSIS We extracted and analysed data according to the methods outlined in the latest Cochrane Handbook for Systematic Reviews of Interventions. Two review authors assessed trial quality in each potentially eligible manuscript and two review authors extracted data. MAIN RESULTS Our previous systematic review included two trials enrolling a total of 100 infants with transient tachypnoea of the newborn (Wiswell 1985; Karabayir 2006). The updated search revealed no new trials. Wiswell 1985 randomised 50 infants to receive either oral furosemide (2 mg/kg body weight at time of diagnosis followed by a 1 mg/kg dose 12 hours later if the tachypnoea persisted) or placebo. Karabayir 2006 randomised 50 infants to receive either intravenous furosemide (2 mg/kg body weight) or an equal volume of normal saline placebo. Neither trial reported on the need for respiratory support. Neither trial demonstrated a statistically significant impact of furosemide on transient tachypnoea of the newborn regarding duration of symptoms or length of hospitalisation. AUTHORS' CONCLUSIONS Diuretics cannot be recommended as treatment for transient tachypnoea of the newborn and it should not be used unless additional data become available. This finding suggests that either furosemide is not effective in promoting resorption of lung fluid, or factors other than delayed resorption of this fluid contribute to the pathogenesis of transient tachypnoea of the newborn. The question remains as to whether furosemide given to the infant (or even to the mother before caesarean section) might shorten the duration of the illness. As elective caesarean section continues at a high level, these two interventions might be worthy of trials.

Abstract
BACKGROUND AND AIMS Premature infants are at high risk for neurodevelopmental impairment (NDI) even in the absence of known brain complications of prematurity. Evaluation of the effectiveness of therapeutic interventions in association to neurodevelopmental outcome is required to improve or prevent the neurodevelopmental consequences of prematurity. The Bayley-III is currently the most commonly applied measurement tool for assessing early development both in clinical practice and research settings. OBJECTIVE To evaluate the relationship between known risk factors and early performance on the Bayley Scales of Infant Development-Third Edition at 12 months adjusted age in premature infants. METHODS Prospective study in a cohort of premature infants with gestational age ≤32 weeks, who underwent comprehensive developmental assessment using the five domains of Bayley Scales, cognitive, language, motor, social emotional and adaptive behavior at 12 months corrected age. Developmental scores were evaluated in relation to environmental influences, therapeutic interventions or practices and complications of prematurity. RESULTS Composite and Subscale scores for the cognitive, language and motor scales were below the 50th percentile, with no significant differences among them. Scores for the social-emotional and adaptive behavior, which are derived from the parent-report questionnaires, were near the average and significantly higher than the scores derived by the examiners. Multiple regression analyses showed that blood transfusions, apart from severely abnormal head ultrasound, gender, being small for gestational age and duration of invasive mechanical ventilation and oxygen administration were consistently related to neurodevelopmental outcome. CONCLUSIONS Bayley-III assessments are important for getting early information about development following premature birth. Parents may overestimate children's performance. Neurodevelopmental outcome is related to several environmental, biological or medical conditions associated with prematurity. Adoption of therapeutic strategies targeting known neonatal risk factors could positively affect neurodevelopmental outcome.

Abstract
OBJECTIVE We sought to determine predictors of adverse neonatal outcomes in women with intrahepatic cholestasis of pregnancy (ICP). STUDY DESIGN This study was a multicenter retrospective cohort study of all women diagnosed with ICP across 5 hospital facilities from January 2009 through December 2014. Obstetric and neonatal complications were evaluated according to total bile acid (TBA) level. Multivariable logistic regression models were developed to evaluate predictors of composite neonatal outcome (neonatal intensive care unit admission, hypoglycemia, hyperbilirubinemia, respiratory distress syndrome, transient tachypnea of the newborn, mechanical ventilation use, oxygen by nasal cannula, pneumonia, and stillbirth). Predictors including TBA level, hepatic transaminase level, gestational age at diagnosis, underlying liver disease, and use of ursodeoxycholic acid were evaluated. RESULTS Of 233 women with ICP, 152 women had TBA levels 10-39.9 μmol/L, 55 had TBA 40-99.9 μmol/L, and 26 had TBA ≥100 μmol/L. There was no difference in maternal age, ethnicity, or prepregnancy body mass index according to TBA level. Increasing TBA level was associated with higher hepatic transaminase and total bilirubin level (P < .05). TBA levels ≥100 μmol/L were associated with increased risk of stillbirth (P < .01). Increasing TBA level was also associated with earlier gestational age at diagnosis (P < .01) and ursodeoxycholic acid use (P = .02). After adjusting for confounders, no predictors were associated with composite neonatal morbidity. TBA 40-99.9 μmol/L and TBA ≥100 μmol/L were associated with increased risk of meconium-stained amniotic fluid (adjusted odds ratio, 3.55; 95% confidence interval, 1.45-8.68 and adjusted odds ratio, 4.55; 95% confidence interval, 1.47-14.08, respectively). CONCLUSION In women with ICP, TBA level ≥100 μmol/L was associated with increased risk of stillbirth. TBA ≥40 μmol/L was associated with increased risk of meconium-stained amniotic fluid.

Abstract
BACKGROUND Acute kidney injury (AKI) impairs electrolyte balance, alters fluid homeostasis and decreases toxin excretion. More recent data suggest it also affects the physiology of distant organs. METHODS We performed a prospective cohort study which invloved 122 premature infants [birth weight (BW) ≤1200 g and/or gestational age (GA) <31 weeks] to determine relationships between AKI and bronchopulmonary dysplasia (BPD)/mortality. Days until oxygen discontinuation was compared between those with and without AKI in survivors who received oxygen for ≥24 h. RESULTS Acute kidney disease, defined by a rise in serum creatinine (SCr) of ≥0.3 mg/dl or an increase in SCr of ≥150%, occurred in 36/122 (30%) of the premature infants. Those with AKI had a 70% higher risk of oxygen requirement or of dying at 28 days of life [relative risk (RR) 1.71, 95% confidence interval (CI) 1.22-2.39; p < 0.002]. This association remained after controlling for GA, pre-eclampsia, 5 min Apgar score and percentage maximum weight change (max % weight Δ) in the first 4 days (RR 1.45, 95% CI 1.07-1.97); p < 0.02). Similar findings were noted for receipt of mechanical ventilation/death by day 28 (adjusted RR 1.53, 95% CI 1.05-2.22; p < 0.03). Those without AKI were 2.5-fold more likely to come off oxygen [hazard ratio (HR) 1.3-5; p < 0.02) than those with AKI, even when controlling for GA, pre-eclampsia, 5 min Apgar and max % weight Δ (multivariate HR 2.0, 95% CI 0.9-4.0; p < 0.06). CONCLUSIONS In premature infants, AKI is associated with BPD/mortality. As AKI could lead to altered lung physiology, interventions to ameliorate AKI could improve long-term BPD.

Abstract
BACKGROUND Despite well established clinical guidelines, performance of long-term oxygen therapy (LTOT) programs shows marked variability among territories. The current study assessed the LTOT program and the health status of patients on LTOT prior to the deployment of community-based integrated care in an urban health district of Barcelona (Spain). AIMS To assess: i) the LTOT program and health status of the patients on LTOT in the health district; ii) their frailty profile; and, iii) the requirements for effective deployment of integrated care services for these patients. METHODS Cross-sectional observational study design including all patients (n = 406) on LTOT living in the health district. Health status, frailty, arterial blood gases, forced spirometry and hand-grip muscle strength were measured. Network analysis of frailty was carried out. RESULTS Adequacy of LTOT prescription (n = 362): 47% and 31% of the patients had PaO2 ≤ 60 mmHg and ≤55 mmHg, respectively. Adherence to LTOT: 31% of all patients used LTOT ≥15 h/d; this figure increased to 67% in those with PaO2≤60 mmHg. Assessment of frailty: Overall, LTOT patients presented moderate to severe frailty. Care complexity was observed in 42% of the patients. CONCLUSIONS Adequacy and adherence to LTOT was poor and many patients were frail and complex. The outcomes of the network analysis may contribute to enhance assessment of frailty in LTOT patients. These observations suggest that an integrated care strategy has the potential to improve the health outcomes of these patients.

Abstract
RATIONALE Oxygen therapy improves survival and function in severely hypoxemic chronic obstructive pulmonary disease (COPD) patients based on two landmark studies conducted over 40 years ago. We hypothesize that oxygen users in the current era may be very different. We examined trends and subject characteristics associated with oxygen therapy use from 2001-2010 in the United States. METHODS We examined Medicare beneficiaries with COPD who received oxygen from 2001 to 2010. COPD subjects were identified by: 1) ≥2 outpatient visits >30 days apart within one year with an encounter diagnosis of COPD; or 2) an acute care hospitalization with COPD as the primary or secondary discharge diagnosis. Oxygen therapy and sustained oxygen therapy were defined as ≥1 and ≥11 claims for oxygen, respectively, in the durable medical equipment file in a calendar year. Primary outcome measures were factors associated with oxygen therapy and sustained oxygen therapy over the study period. RESULTS Oxygen therapy increased from 33.7% in 2001 to 40.5% in 2010 (p-value of trend <0.001). Sustained oxygen therapy use increased from 19.5% in 2001, peaked in 2008 to 26.9% and declined to 18.5% in 2010. The majority of subjects receiving oxygen therapy and sustained oxygen therapy were female. Besides gender, factors associated with any oxygen use or sustained oxygen therapy were non-Hispanic white race, low socioeconomic status and ≥2 comorbidities. CONCLUSIONS Any oxygen use among fee-for service Medicare beneficiaries with COPD is high. Current users of oxygen are older females with multiple comorbidities. Decline in sustained oxygen therapy use after 2008 may be related to reimbursement policy change.

Abstract
BACKGROUND In preterm newborns, the ductus arteriosus frequently fails to close and the infants require medical or surgical closure of the patent ductus arteriosus (PDA). A PDA can be treated surgically or medically with one of two prostaglandin inhibitors, indomethacin or ibuprofen. Case reports suggest that paracetamol may be an alternative for the closure of a PDA. Concerns have been raised that in neonatal mice paracetamol may cause adverse effects on the developing brain, and an association between prenatal exposure to paracetamol and later development of autism or autism spectrum disorder has been reported. OBJECTIVES To determine the efficacy and safety of intravenous or oral paracetamol compared with placebo or no intervention, intravenous indomethacin, intravenous or oral ibuprofen, or with other cyclo-oxygenase inhibitors for closure of a PDA in preterm or low-birth-weight infants. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group. This included electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL, Cochrane Library), MEDLINE, EMBASE and CINAHL. We searched abstracts from the meetings of the Pediatric Academic Societies and the Perinatal Society of Australia and New Zealand. We searched clinicaltrials.gov; controlled-trials.com; anzctr.org.au; World Health Organization International Clinical Trials Registry Platform at who.int/ictrp for ongoing trials and the Web of Science for articles quoting identified randomised controlled trials. We searched the first 200 hits on Google Scholar(TM) to identify grey literature. All searches were conducted in December 2013. A repeat search of MEDLINE in August 2014 did not identify any new trials. SELECTION CRITERIA We identified two randomised controlled trials (RCTs) that compared oral paracetamol to oral ibuprofen for the treatment of an echocardiographically diagnosed PDA in infants born preterm (≤ 34 weeks postmenstrual age (PMA)). DATA COLLECTION AND ANALYSIS We performed data collection and analyses in accordance with the methods of the Cochrane Neonatal Review Group. MAIN RESULTS Two unmasked studies of treatment of PDA that enrolled 250 infants were included. The sequence of randomisation and the allocation to treatment groups were concealed in both studies. In one study the cardiologist assessing PDA closure was blinded to group allocation of the infant. In the other study it was not stated if that was the case or not. The quality of the trials, using GRADE, was low for the primary outcome of PDA closure and moderate for all other important outcomes. There was no significant difference between treatment with oral paracetamol versus oral ibuprofen for failure of ductal closure after the first course of drug administration (typical relative risk (RR) 0.90, 95% confidence interval (CI) 0.67 to 1.22; typical risk difference (RD) -0.04, 95% CI -0.16 to 0.08; I(2) = 0 % for RR and 23% for RD).There were no significant differences between the paracetamol and the ibuprofen groups in the secondary outcomes except for 'duration for need of supplemental oxygen' (mean difference -12 days, 95% CI -23 days to -2 days; 1 study, n = 90) and for hyperbilirubinaemia (RR 0.57, 95% CI 0.34 to 0.97; RD -0.15, 95% CI -0.29 to -0.01; number needed to treat to benefit (NNTB) 7, 95% CI 3 to 100 in favour of paracetamol; 1 study, n = 160). AUTHORS' CONCLUSIONS Although a limited number of infants with a PDA have been studied in randomised trials of low to moderate quality according to GRADE, oral paracetamol appears to be as effective in closing a PDA as oral ibuprofen. In view of a recent report in mice of adverse effects on the developing brain from paracetamol, and another report of an association between prenatal paracetamol and the development of autism or autism spectrum disorder in childhood, long-term follow-up to at least 18 to 24 months postnatal age must be incorporated in any studies of paracetamol in the newborn population. Such trials are required before any recommendations for the use of paracetamol in the newborn population can be made.

Abstract
OBJECTIVE To study the demographic and clinical features of Retinopathy of Prematurity in urban Punjab. METHODS The cross-sectional study was performed at Hameed Latif Hospital, Lahore, from April 2010 to October 2013 and comprised neonates born with birth weight less than 2000 g, gestational age less than 37 weeks, or those who were considered high risk for Retinopathy of Prematurity. Variables recorded included history, birth weight, gestational age, oxygen supplementation, development of Retinopathy of Prematurity, and laser treatment. Data was analysed using SPSS 17. RESULTS There were 285 neonates in the study with a mean birth weight of 1280.34 ± 350.43 g and mean gestational age being 29.38 ± 3.14 weeks. Overall, 167 (58.6%) received supplemental oxygen, 86(30.2%) were anaemic and 44 (15.4%) received blood transfusion. Besides, 47 (16.5%) premature babies were product of multiple gestation, 34 (11.9%) were having respiratory distress, 25 (8.8%) had sepsis and received intravenous antibiotics, 70(24.6%) developed Retinopathy of Prematurity, and 22 (7.7%) developed threshold disease and received laser treatment at mean gestational age of 32.11 ± 2.53 weeks. CONCLUSION Screening is key to preventing childhood blindness caused by Retinopathy of Prematurity. Prematurity, low birth weight and supplemental oxygen therapy are significant risk factors for the condition.

Abstract
The Safe Home Care Project investigated both qualitatively and quantitatively a range of occupational safety and health hazards, as well as injury and illness prevention practices, among home care aides in Massachusetts. This article reports on a hazard identified by aides during the study's initial focus groups: smoking by home care clients on long-term oxygen therapy. Following the qualitative phase we conducted a cross-sectional survey among 1,249 aides and found that medical oxygen was present in 9 percent of aide visits (314 of aides' 3,484 recent client visits) and that 25 percent of clients on oxygen therapy were described as smokers. Based on our findings, the Board of Health in a local town conducted a pilot study to address fire hazards related to medical oxygen. Medical oxygen combined with smoking or other sources of ignition is a serious fire and explosion hazard that threatens not only workers who visit homes but also communities.

Abstract
BACKGROUND Chronic lung disease remains a major problem in neonatal intensive care units. Persistent inflammation in the lungs is the most likely underlying pathogenesis. Corticosteroids have been used to either prevent or treat chronic lung disease because of their potent anti-inflammatory effects. OBJECTIVES To examine the relative benefits and adverse effects of postnatal corticosteroids commenced within the first seven days of life to preterm infants at risk of developing chronic lung disease. SEARCH METHODS We sought randomised controlled trials (RCTs) of postnatal corticosteroid therapy from the Cochrane Central Register of Controlled Trials (CENTRAL, 2013, Issue 8), MEDLINE (1966 to August 2013), handsearching paediatric and perinatal journals, and by examining previous review articles and information received from practising neonatologists. We contacted authors of all studies, where possible, to confirm details of reported follow-up studies, or to obtain any information about long-term follow-up where none had been reported. SELECTION CRITERIA We selected RCTs of postnatal corticosteroid treatment within the first seven days of life (early) in high-risk preterm infants for this review. Most studies evaluated the use of dexamethasone but we also included studies that assessed hydrocortisone, even if it was used primarily to manage hypotension. DATA COLLECTION AND ANALYSIS We extracted and analysed data regarding clinical outcomes that included mortality, chronic lung disease, death or chronic lung disease, failure to extubate, complications during the primary hospitalisation, and long-term health outcomes. MAIN RESULTS Twenty-nine RCTs enrolling a total of 3750 participants were eligible for inclusion in this review. The overall risk for bias was probably low as all were randomised controlled trials, and most trials have used rigorous methods. There were significant benefits for the following outcomes: lower rates of failure to extubate and decreased risks of chronic lung disease at both 28 days and 36 weeks' postmenstrual age, death or chronic lung disease at 28 days and 36 weeks' postmenstrual age, patent ductus arteriosus and ROP, including severe ROP. There were no significant differences in the rates of neonatal or subsequent mortality, infection, severe intraventricular haemorrhage, periventricular leukomalacia, necrotising enterocolitis or pulmonary haemorrhage. Gastrointestinal bleeding and intestinal perforation were important adverse effects. The risks of hyperglycaemia, hypertension, hypertrophic cardiomyopathy and growth failure were also increased. In the 12 trials that reported late outcomes, several adverse neurological effects were found at follow-up examinations, including developmental delay (not defined), cerebral palsy and abnormal neurological examination. However, major neurosensory disability was not significantly increased, either overall in the seven studies where this outcome could be determined, or in the two individual studies where the rates of cerebral palsy or abnormal neurological examination were significantly increased. Moreover, the rates of the combined outcomes of death or cerebral palsy, or of death or major neurosensory disability, were not significantly increased. Dexamethasone was used in most studies (n = 20); only nine studies used hydrocortisone. In subgroup analyses by type of corticosteroid, most of the beneficial and harmful effects were attributable to dexamethasone; hydrocortisone had little effect on any outcomes except for an increase in intestinal perforation and a borderline reduction in patent ductus arteriosus. AUTHORS' CONCLUSIONS The benefits of early postnatal corticosteroid treatment (≤ 7 days), particularly dexamethasone, may not outweigh the adverse effects of this treatment. Although early corticosteroid treatment facilitates extubation and reduces the risk of chronic lung disease and patent ductus arteriosus, it causes short-term adverse effects including gastrointestinal bleeding, intestinal perforation, hyperglycaemia, hypertension, hypertrophic cardiomyopathy and growth failure. Long-term follow-up studies report an increased risk of abnormal neurological examination and cerebral palsy. However, the methodological quality of the studies determining long-term outcomes is limited in some cases; the surviving children have been assessed predominantly before school age, and no study has been sufficiently powered to detect important adverse long-term neurosensory outcomes. There is a compelling need for the long-term follow-up and reporting of late outcomes, especially neurological and developmental outcomes, among surviving infants who participated in all randomised trials of early postnatal corticosteroid treatment. Hydrocortisone in the doses and regimens used in the reported RCTs has few beneficial or harmful effects and cannot be recommended for the prevention of chronic lung disease.

Abstract
BACKGROUND Planning for the reliable and cost-effective supply of a health service commodity such as medical oxygen requires an understanding of the dynamic need or 'demand' for the commodity over time. In developing country health systems, however, collecting longitudinal clinical data for forecasting purposes is very difficult. Furthermore, approaches to estimating demand for supplies based on annual averages can underestimate demand some of the time by missing temporal variability. METHODS A discrete event simulation model was developed to estimate variable demand for a health service commodity using the important example of medical oxygen for childhood pneumonia. The model is based on five key factors affecting oxygen demand: annual pneumonia admission rate, hypoxaemia prevalence, degree of seasonality, treatment duration, and oxygen flow rate. These parameters were varied over a wide range of values to generate simulation results for different settings. Total oxygen volume, peak patient load, and hours spent above average-based demand estimates were computed for both low and high seasons. FINDINGS Oxygen demand estimates based on annual average values of demand factors can often severely underestimate actual demand. For scenarios with high hypoxaemia prevalence and degree of seasonality, demand can exceed average levels up to 68% of the time. Even for typical scenarios, demand may exceed three times the average level for several hours per day. Peak patient load is sensitive to hypoxaemia prevalence, whereas time spent at such peak loads is strongly influenced by degree of seasonality. CONCLUSION A theoretical study is presented whereby a simulation approach to estimating oxygen demand is used to better capture temporal variability compared to standard average-based approaches. This approach provides better grounds for health service planning, including decision-making around technologies for oxygen delivery. Beyond oxygen, this approach is widely applicable to other areas of resource and technology planning in developing country health systems.

Abstract
BACKGROUND Pulmonary hypertension (PH) often correlates with respiratory disease severity. Right heart catheterization (RHC) is recommended for the definitive diagnosis of PH associated with respiratory disease (R-PH). However, no previous studies have evaluated the perceived necessity for pulmonologists to use RHC for R-PH diagnosis, or the management of R-PH in Japan. METHODS Questionnaires were mailed to 855 institutions, approved by the Japanese Respiratory Society. Questions included the prevalence and necessity of RHC and other methods in R-PH diagnosis, and current trends in the treatment of R-PH. RESULTS Questionnaires were returned from 289 institutions (34%). Patients with R-PH were examined by pulmonologists in 89% of institutions; some pulmonologists performed echocardiography (15%) and some RHC (13%). Echocardiography was used to diagnose R-PH in 99% of institutions and RHC was used in 36%. RHC was considered in cases of suspected PH in 49% of institutions and prior to initiation of pulmonary arterial hypertension (PAH)-specific therapy in 57%. Of patients diagnosed with R-PH, 47% were treated with ambulatory oxygen therapy. Furthermore, 98 of 145 institutions used PAH-specific therapy to treat R-PH. Of the 1355 patients who underwent RHC as a part of PH evaluation, 29% were confirmed to have PH, and 8% had severe PH with a mean pulmonary arterial pressure of ≥35mmHg. CONCLUSIONS The current diagnostic and treatment modalities for R-PH in Japan were evaluated. Although few pulmonologists perform RHC for R-PH diagnosis in Japan, more than half consider using RHC for patients before initiating PAH-specific therapy.

Abstract
OBJECTIVES Analyze developments in the clinical adequacy of prescribing continuous home oxygen therapy to current regulations in the Andalusian Health Service. METHODOLOGY Were reviewed in a previous study requirements and continuing new domiciliary oxygen therapy conducted from January 2008 to December 2009. It constituted a Monitoring Committee Multidisciplinary and turned to analyzing the appropriateness of prescribing after two pharmaceutical interventions from April 2011 to March 2012. Statistical analysis was performed by SPSS 15.0 for Windows, the dependent variable being the correct blade adjustment to the first prescription and then, and as independent prescribing different units. In cases in which the prescribing correct sheet, variables were analyzed mandatory. RESULTS 163 prescriptions were checked manually with a rate of compliance with the regulations of 66.30%, slightly higher than the results of the previous study (55.72% in 2008, 47.70% in 2009). The intervention did not achieve a greater degree the outlook for lack of financial and material resources, affecting one of the fundamental objectives were patient reviews. CONCLUSIONS Pharmaceutical intervention has ensured that the prescription conforms to the rules and perform better, but has not been able to control the issue of revisions to rely on other medical and administrative units requesting increased technological and human resources to facilitate control.

Abstract
OBJECTIVE To examine the functional outcomes of children who underwent a tracheostomy in the initial hospitalization after birth and to determine their correlates. STUDY DESIGN We administered the validated 43-item Functional Status-II (FS-II) questionnaire by Stein and Jessop over the telephone to caregivers of surviving children. The FS-II items generated a total score, age-specific: (1) total; (2) general health (GH); and (3) responsiveness, activity, or interpersonal functioning (IPF) scores in specific age group categories. RESULTS FS-II was administered to 51/62 (82.2%) survivors at a median (range) age of 5 (1-10) years; 27% children were on the ventilator and 43% required devices. About 40% of children had a median of 1 (1-4) hospitalization in the previous 6 months. Scores were >2 SD below means in 55%, 24%, and 55% cases for age-specific T, GH, and R/A/IPF scores respectively. The T and R/A/IPF scales were significantly higher in those with private, rather than public, maternal insurance, as were T and R/A/IPF scores for children ≥ 4 years, compared with younger children. On regression analysis, FS-II T, GH, and R/A/IPF scores were independently associated with maternal private insurance (P = .02). R/A/IPF scores were also significantly associated with corrected age at FS-II administration. CONCLUSIONS One-third of surviving children who underwent tracheostomy during their initial hospitalization remained technology-dependent. The parental FS-II questionnaires revealed low R/A/IPF scores, especially at younger ages and in those with maternal public insurance. Further research on family-level interventions to improve functional outcomes in this population is warranted.

Abstract
BACKGROUND Transient tachypnoea of the newborn (TTN) results from delayed clearance of lung liquid and is a common cause of admission of full term infants to neonatal intensive care units. The condition is particularly common after elective caesarean section. Conventional treatment involves appropriate oxygen administration and continuous positive airway pressure in some cases. Most infants receive antibiotic therapy. Hastening the clearance of lung liquid may shorten the duration of the symptoms and reduce complications. OBJECTIVES To determine whether furosemide administration reduces the duration of oxygen therapy and respiratory symptoms and shortens hospital stay in term infants with transient tachypnoea of the newborn. SEARCH METHODS An updated search was carried out in January 2013 of the following databases: The Cochrane Library issue 1, 2013 (CENTRAL, The Cochrane Central Register of Controlled Trials), PubMed, MEDLINE via Ovid, CINAHL via OVID and EMBASE. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials that compared the effect of furosemide administration versus placebo or no treatment in infants of less than seven days of age, born at 37 or more weeks of gestation with the clinical picture of transient tachypnoea of the newborn. DATA COLLECTION AND ANALYSIS We extracted and analysed data according to the methods outlined in the latest Cochrane Handbook for Systematic Reviews of Interventions. Two review authors assessed trial quality in each potentially eligible manuscript and two review authors extracted data. MAIN RESULTS Our updated review includes two completed trials. Wiswell 1985 and Karabayir 2006 investigated 100 infants with transient tachypnoea of the newborn. Wiswell 1985 randomised 50 infants to receive either oral furosemide (2 mg/kg body weight at time of diagnosis followed by a 1 mg/kg dose 12 hours later if the tachypnoea persisted) or placebo. Karabayir 2006 randomised 50 infants to receive either intravenous furosemide (2 mg/kg body weight) or an equal volume of normal saline placebo. Neither trial reported on the need for respiratory support. Neither trial demonstrated a statistically significant impact of furosemide on transient tachypnoea of the newborn regarding duration of symptoms or length of hospitalisation. AUTHORS' CONCLUSIONS Oral or intravenous furosemide cannot be recommended as treatment for transient tachypnoea of the newborn and it should not be used unless additional data become available. This finding suggests that either furosemide is not effective in promoting resorption of lung fluid, or factors other than delayed resorption of this fluid contribute to the pathogenesis of transient tachypnoea of the newborn. The question remains as to whether furosemide given to the infant (or even to the mother before caesarean section) might shorten the duration of the illness. As elective caesarean section continues at a high level, these two interventions might be worthy of trials.

Abstract
CONTEXT Clinicians prescribe and administer oxygen in response to reports of dyspnea, in the face of dropping oxygen saturation, as a "routine" comfort intervention, or to support anxious family members. Oxygen may produce nasal irritation and increase the cost of care. OBJECTIVES To determine the benefit of administering oxygen to patients who are near death. METHODS A double-blind, repeated-measure observation with the patient as his/her own control was conducted. The Respiratory Distress Observation Scale(©) measured presence and intensity of distress at baseline and at every gas or flow change. Medical air, oxygen, and no flow were randomly alternated every 10 minutes via nasal cannula with patients who were near death, at risk for respiratory distress, with no distress at the baseline of testing. Each patient had two encounters under each condition, yielding six encounters per patient. RESULTS Patients were 66% female, 34% white, and 66% African American, and ages 56-97 years. Patients had heart failure (25%), chronic obstructive pulmonary disease (34%), pneumonia (41%), or lung cancer (9%). Most (91%) patients tolerated the protocol with no change in respiratory comfort. Three patients (9%) displayed distress and were restored to baseline oxygen; one patient died during the protocol while displaying no distress. Repeated-measure analysis of variance revealed no differences in the Respiratory Distress Observation Scale under changing gas and flow conditions. CONCLUSION The routine application of oxygen to patients who are near death is not supported. The n-of-1 trial of oxygen in clinical practice is appropriate in the face of hypoxemic respiratory distress.

Abstract
Historically, the progress of long term-oxygen therapy (LTOT) in Japan has been characterized by collaboration among academic groups, policy makers, and industrial companies. The public health insurance program has covered the cost of LTOT since 1985. Thomas Petty's group in Denver enthusiastically carried out the public implementation of LTOT and conveyed the concept of pulmonary rehabilitation for the processing with LTOT. Although the target diseases of LTOT in Japan tended to be chronic obstructive pulmonary disease or sequelae of primary lung tuberculosis, it was soon applied for cardiac diseases as well as other pulmonary diseases. Together with increasing medical costs for geriatric patients, the political conversion from hospital based care of a traditional style to home care system has been performed, with two background reasons: the improvement of quality of life of patients and the reduction of the medical expense. Presently, LTOT plays a pivotal role in the successful implementation of home respiratory care for elderly patients. In addition, this promotes comprehensive pulmonary rehabilitation, a team approach, and close liaisons between primary care and hospitals. Currently, the total number of patients using LTOT exceeds 150,000. In Japan, LTOT resulted in an advancement in the medical care as well as in administrative decision to introduce it as a nationwide system after analyzing the results of opinion polls of patients with respiratory failure. However, the recent great earthquake in East Japan revealed that many unresolved problems remain for these patients, and these issues are of great concern.

Abstract
INTRODUCTION Variation of respiratory care is described between centers around the world. The Italian Neonatal Network (INN), as a national group of the Vermont-Oxford Network (VON) allows to perform a wide analysis of respiratory care in very low birth weight infants. METHODS We analyzed the dataset of infants enrolled in the INN in 2009 and 2010 and, for surfactant administration only, from 2006 to 2010 from 83 participating centers. All definitions are those of the (VON). A questionnaire analysis was also performed with a questionnaire on centers practices. RESULTS We report data for 8297 infants. Data on ventilator practices and outcomes are outlined. Variation for both practices and outcome is found. Trend in surfactant administration is also analyzed. CONCLUSIONS. The great variation across hospitals in all the surveyed techniques points to the possibility of implementing potentially better practices with the aim of reducing unwanted variation. These data also show the power of large neonatal networks in identifying areas for potential improvement.
