- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

- Background: Experiments have shown improved cardiovascular stability in lambs if umbilical cord clamping is postponed until positive pressure ventilation is started. Studies on intact cord resuscitation on human term infants are sparse. The purpose of this study was to evaluate differences in clinical outcomes in non-breathing infants between groups, one where resuscitation is initiated with an intact umbilical cord (intervention group) and one group where cord clamping occurred prior to resuscitation (control group).Methods: Randomized controlled trial, inclusion period April to August 2016 performed at a tertiary hospital in Kathmandu, Nepal. Late preterm and term infants born vaginally, non-breathing and in need of resuscitation according to the 'Helping Babies Breathe' algorithm were randomized to intact cord resuscitation or early cord clamping before resuscitation. Main outcome measures were saturation by pulse oximetry (SpO2), heart rate and Apgar at 1, 5 and 10 minutes after birth.Results: At 10 minutes after birth, SpO2 (SD) was significantly higher in the intact cord group compared to the early cord clamping group, 90.4 (8.1) vs 85.4 (2.7) %, P < .001). In the intact cord group, 57 (44%) had SpO2 < 90% after 10 minutes, compared to 93 (100%) in the early cord clamping group, P < 0.001. SpO2 was also significantly higher in the intervention (intact cord) group at one and five minutes after birth. Heart rate was lower in the intervention (intact cord) group at one and five minutes and slightly higher at ten minutes, all significant findings. Apgar score was significantly higher at one, five and ten minutes. At 5 minutes, 23 (17%) had Apgar score < 7 in the intervention (intact cord) group compared to 26 (27%) in the early cord clamping group, P < .07. Newborn infants in the intervention (intact cord) group started to breathe and establish regular breathing earlier than in the early cord clamping group.Conclusions: This study provides new and important information on the effects of resuscitation with an intact umbilical cord. The findings of improved SpO2 and higher Apgar score, and the absence of negative consequences encourages further studies with longer follow-up.Trial registration: Clinicaltrials.gov NCT02727517, 2016/4/4.

Tidskriftsartikel (refereegranskat)abstract
- Background: Globally, 15 million babies were born prematurely in 2012, with 37.6 % of them in South Asia. About 32.4 million infants were born small for gestational age (SGA) in 2010, with more than half of these births occurring in South Asia. In Nepal, 14 % of babies were born preterm and 39.3 % were born SGA in 2010. We conducted a study in a tertiary hospital of Nepal to assess the level of risk for neonatal mortality among babies who were born prematurely and/or SGA. Methods: This case-control study was completed over a 15-month period between July 2012 and September 2013. All neonatal deaths that occurred during the study period were included as cases and 20 % of women with live births were randomly selected as referents. Information on potential risk factors was taken from medical records and interviews with the women. Logistic regression analyses were conducted to determine the level of risk for neonatal mortality among babies born preterm and/or SGA. Results: During this period, the hospital had an incidence of preterm birth and SGA of 8.1 and 37.5 %, respectively. In the multivariate model, there was a 12-fold increased risk of neonatal death among preterm infants compared to term. Babies who were SGA had a 40 % higher risk of neonatal death compared to those who were not. Additionally, babies who were both preterm and SGA were 16 times more likely to die during the neonatal period. Conclusions: Our study showed that the risk of neonatal mortality was highest when the baby was born both preterm and SGA, followed by babies who were born preterm, and then by babies who were SGA in a tertiary hospital in Nepal. In tertiary care settings, the risk of mortality for babies who are born preterm and/or SGA can be reduced with low-cost interventions such as Kangaroo Mother Care or improved management of complications through special newborn care or neonatal intensive care units. The risk of death for babies who are born prematurely and/or SGA can thus be used as an indicator to monitor the quality of care for these babies in health facility settings.

- Aim: This paper examines the change in neonatal resuscitation practices after the implementation of the Helping Babies Breathe (HBB) programme.Methods: A systematic review was carried out on studies reporting the impact of HBB programmes among the literature found in Medline, POPLINE, LILACS, African Index Medicus, Cochrane, Web of Science and Index Medicus for the Eastern Mediterranean Region database. We selected clinical trials with randomised control, quasi-experimental and cross-sectional designs. We used a data extraction tool to extract information on intervention and outcome reporting. We carried out a meta-analysis of the extracted data on the neonatal resuscitation practices following HBB programme using Review Manager.Results: Four studies that reported on neonatal resuscitation practices before and after the implementation of the HBB programme were identified. The pooled results showed no changes in the use of stimulation (RR-0.54; 95% CI, 0.21-1.42), suctioning (RR-0.48; 95% CI, 0.18-1.27) and bag-and-mask ventilation (RR-0.93; 95% CI, 0.47-1.83) after HBB training. The proportion of babies receiving bag-and-mask ventilation within the Golden Minute of birth increased by more than 2.5 times (RR-2.67; 95% CI, 2.17-3.28).Conclusion: The bag-and-mask ventilation within Golden minute has improved following the HBB programme. Implementation of HBB training improves timely initiation of bag-and-mask ventilation within one minute of birth.

Tidskriftsartikel (refereegranskat)abstract
- AIM: Bronchopulmonary dysplasia (BPD) is a frequent chronic lung disease in preterm infants, and we aimed to identify factors associated with this condition in infants with respiratory distress syndrome (RDS).METHODS: This case-control study, using national Swedish data, included 2255 preterm infants, born before 33 gestational weeks. The 667 BPD cases were oxygen dependent at 36 weeks' postmenstrual age, and the 1558 controls only had RDS. Comparisons included perinatal conditions and pharmacological treatments. Adjusted odds ratios with 95% confidence intervals were calculated in a conditional logistic regression model, with gestational age as the conditioning term.RESULTS: An increased risk of BPD was associated with prelabour preterm rupture of membranes of more than 1 week (3.35, 2.16-5.19), small for gestational age (2.73, 2.11-3.55), low Apgar score (1.37, 1.05-1.81), patent ductus arteriosus (1.70, 1.33-2.18), persistent pulmonary hypertension (5.80, 3.21-10.50), pulmonary interstitial emphysema (2.78, 1.37-5.64), pneumothorax (2.95, 1.85-4.72), late onset infections (2.69, 1.82-3.98), intubation (1.56, 1.20-2.03), chest compressions (2.05, 1.15-3.66) and mechanical ventilation (2.16, 1.69-2.77), but not antenatal corticosteroids.CONCLUSION: Growth restriction and inflammation increased the risk of BPD in preterm infants and prelabour preterm rupture of membranes, small for gestational age, low Apgar score or need for resuscitation should raise clinical suspicions.

- Background: Little is know about whether the effects of community engagement interventions for child survival in low-income and middle-income settings are sustained. Seasonal variation and secular trend may blur the data. Neonatal mortality was reduced in a cluster-randomised trial in Vietnam where laywomen facilitated groups composed of local stakeholders employing a problem-solving approach for 3 years. In this analysis, we aim at disentangling the secular trend, the seasonal variation and the effect of the intervention on neonatal mortality during and after the trial.Methods: In Quang Ninh province, 44 communes were allocated to intervention and 46 to control. Births and neonatal deaths were assessed in a baseline survey in 2005, monitored during the trial in 2008–2011 and followed up by a survey in 2014. Time series analyses were performed on monthly neonatal mortality data.Results: There were 30 187 live births and 480 neonatal deaths. The intervention reduced the neonatal mortality from 19.1 to 11.6 per 1000 live births. The reduction was sustained 3 years after the trial. The control areas reached a similar level at the time of follow-up. Time series decomposition analysis revealed a downward trend in the intervention areas during the trial that was not found in the control areas. Neonatal mortality peaked in the hot and wet summers.Conclusions: A community engagement intervention resulted in a lower neonatal mortality rate that was sustained but not further reduced after the end of the trial. When decomposing time series of neonatal mortality, a clear downward trend was demonstrated in intervention but not in control areas.Trial registration number: ISRCTN44599712, Post-results.

Respiratory tract infections in children with congenital heart disease
- 2016
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Respiratory Syncytial Virus (RSV) infection is common among young children. Congenital Heart Disease (CHD) is a risk factor of severe illness and hospitalization. Palivizumab prophylaxis reduces the severity of RSV infection and reduces the risk of hospitalization for children at high risk of severe illness, such as children born premature or with CHD.The aim of this thesis was to evaluate compliance with national guidelines for prophylactic treatment and to study the Relative Risk (RR) of hospitalization due to RSV and unspecified Respiratory Tract Infection (RTI) for children with CHD.In a prospective study, questionnaires were sent to all paediatric cardiology centres in Sweden with questions about prophylactic treatment. Hospitalization rates were retrieved from the national inpatient registry. Heart defects were grouped according to type and the relative risk of hospitalization was calculated for each group and for summer and winter seasons.Half of the patients received prophylactic treatment later than recommended in the guidelines. The risk of hospitalization due to RSV infection was increased (RR=2.06 95% CI 1.6-2.6; p < 0.0001) for children with CHD compared to children without CHD. The RR of hospitalization was also increased for all CHD subgroups, and was further increased during summer for children with the more severe CHD.We conclude that guidelines for prophylactic treatment were not followed and that the risk of hospitalization due to RSV and unspecified RTI was increased for all subgroups of CHD. The risk was increased both during winter and summer and we therefore argue that information to health personnel and parents should include that the risk of severe RTI is present all year round for children with CHD.

- BACKGROUND: Improving the performance of health workers on neonatal resuscitation will be critical to ensure that the babies are effectively ventilated. We conducted a study to evaluate whether a bag-and-mask ventilation with monitor is effective in improving neonatal resuscitation practice in a simulated setting.METHODS: This is a cross-over design conducted in 6 public hospitals with 82 health workers of Nepal nested over a large scale stepped wedged quality improvement project. A one-day training on neonatal resuscitation was conducted. At the end of the training, participants were evaluated on the bag-and-mask ventilation performance in a manikinbased on the tidal volume, positive end expiratory pressure and air leakage from the maskin two sessions (monitor displayed versus hidden). The comparison of the neonatal resuscitation performance with and without monitor displayed is calculated. We also conducted assessment of confidence with or without monitor of the health workers.RESULTS: Adequacy of ventilation using bag-and-mask was better when the health workers were displayed monitor (90%) vs without monitor (76%) (p<0.01). The air leakage from the mask reduced when the monitor was displayed (12%) vs without (30%). The PEEP improved when the health workers used monitor as guide to conduct neonatal resuscitation in the manikin then without monitor displayed. The participants felt more confident performing ventilations during the visible sessions.CONCLUSIONS: The ventilation function monitor helped participants to improve their ventilation skills through realtime feedback of important ventilation parameters. Clinical evaluation of needs to be done to assess the effectiveness of the device.
