Maternal and perinatal outcomes and pharmacological management of Covid-19 infection in pregnancy: a systematic review protocol

Over 4.2 million confirmed cases and more than 285,000 deaths, COVID-19 pandemic continues to harm significant number of people worldwide. Several studies have reported the impact of COVID-19 in general population; however, there is scarcity of information related to pharmacological management and maternal and perinatal outcomes during the pandemic. Altered physiological, anatomical, and immunological response during pregnancy makes it more susceptible to infections. Furthermore, during pregnancy, a woman undergoes multiple interactions with the health care system that increases her chance of getting infected; therefore, managing pregnant population presents a unique challenge. This systematic review seeks to answer the following questions in relation to COVID-19: What are the different clinical characteristics presented in maternal and perinatal population? What are the different maternal and perinatal outcome measures reported? What are the distinct therapeutic interventions reported to treat COVID-19? Is it safe to use "medications" used in the treatment of COVID-19 during antenatal, perinatal, postnatal, and breastfeeding? The search will follow a comprehensive, sequential three step search strategy. Several databases relevant to COVID-19 and its impact on pregnancy including Medline, CINAHL, and LitCovid will be searched from the inception of the disease until the completion of data collection. The quality of this search strategy will be assessed using Peer Review of Electronic Search Strategies Evidence-Based Checklist (PRESS EBC). An eligibility form will be developed for a transparent screening and inclusion/exclusion of studies. All studies will be sent to RefWorks, and abstraction will be independently performed by two researchers. Risk of bias will be assessed using Cochrane Risk of Bias tool for randomized controlled trials, Newcastle-Ottawa Quality Assessment Scale for non-randomized studies, and for case reports, Murad et al. tool will be used. Decision to conduct meta-analysis will be based on several factors including homogeneity and outcome measures reported; otherwise, a narrative synthesis will be deemed appropriate. This systematic review will summarize the existing data on effect of COVID-19 on maternal and perinatal population. Furthermore, to the best of our knowledge, this is the first systematic review addressing therapeutic management and safety of medicines to treat COVID-19 during pregnancy and breastfeeding. This systematic review has been registered and published with Prospero ( CRD42020172773 )

Outcomes of 28+1 to 32+0 Weeks Gestation Babies in the State of Qatar: Finding Facility-Based Cost Effective Options for Improving the Survival of Preterm Neonates in Low Income Countries

In this retrospective study we did a comparative analysis of the outcome of 28+1 to 32+0 weeks gestation babies between the State of Qatar and some high income countries with an objective of providing an evidence base for improving the survival of preterm neonates in low income countries. Data covering a five year period (2002–2006) was ascertained on a pre-designed Performa. A comparative analysis with the most recent data from VON, NICHD, UK, France and Europe was undertaken. Qatar’s 28+1 to 32+0 weeks Prematurity Rate (9.23 per 1,000 births) was less than the UK’s (p < 0.0001). Of the 597 babies born at 28+1 to 32+0 weeks of gestation, 37.5% did not require any respiratory support, while 31.1% required only CPAP therapy. 80.12% of the MV and 96.28% of CPAP therapy was required for <96 hours. 86.1% of the mothers had received antenatal steroids. The 28+1 to 32+0 weeks mortality rate was 65.3/1,000 births with 30.77% deaths attributable to a range of lethal congenital and chromosomal anomalies. The survival rate increased with increasing gestational age (p < 0.001) and was comparable to some high income countries. The incidence of in hospital pre discharge morbidities in Qatar (CLD 2.68%, IVH Grade III 0.84%, IVH Grade IV 0.5%, Cystic PVL 0.5%) was less as compared to some high income countries except ROP ≥ Stage 3 (5.69%), which was higher in Qatar. The incidence of symptomatic PDA, NEC and severe ROP decreased with increasing gestational age (p < 0.05). We conclude that the mortality and in hospital pre discharge morbidity outcome of 28+1 to 32+0 weeks babies in Qatar are comparable with some high income countries. In two thirds of this group of preterm babies, the immediate postnatal respiratory distress can be effectively managed by using two facility based cost effective interventions; antenatal steroids and postnatal CPAP. This finding is very supportive to the efforts of international perinatal health care planners in designing facility-based cost effective options for low income countries

Stüve-Wiedemann syndrome (A very rare case in Qatar)

Background: Stüve-Wiedemann syndrome (STWS) is an extremely uncommon disorder, which results in bent-bone dysplasia and dysfunction of the autonomic nervous system that controls involuntary processes, such as body temperature and breathing. In infants, this can result in respiratory distress, feeding and swallowing problems, and hyperthermic episodes. While STWS usually leads to infant mortality, some STWS patients might survive into early adulthood. The condition is caused by a mutation in the leukemia inhibitory factor receptor (LIFR) gene, which is inherited in an autosomal-recessive pattern. In this paper, we present a very rare case of STWS in Qatar. Case description: The case was a female baby with the features of STWS. The parents were known carriers of this syndrome with a history of a previous child with the same condition. The baby was the product of a consanguineous marriage. After delivery, the diagnosis of STWS was confirmed by clinical features and genetic testing. Consultation with the related subspecialties was requested for the management of the case. Conclusion: STWS is a rare disorder accompanied by bent-bone dysplasia and autonomic dysfunction that is generally caused by the autosomal recessive inheritance of a mutated LIFR gene. The symptoms of STWS are the result of a lack of LIFR signaling. There is currently no treatment available for STWS, but the symptoms are managed accordingly

Cost-effectiveness of Oral Versus Intravenous Ibuprofen Therapy in Preterm Infants With Patent Ductus Arteriosus in the Neonatal Intensive Care Setting: A Cohort-based Study

Purpose: Use of ibuprofen for the patent ductus arteriosus (PDA) has become increasingly common. This study aimed to evaluate the clinical and economic impact of oral ibuprofen versus intravenous ibuprofen for PDA among preterm infants. Methods: This retrospective, cohort-based pilot study examined the clinical and economic associations of oral versus intravenous ibuprofen for PDA. A decision-analytic model was constructed, from the hospital perspective, to follow the oral versus intravenous administrations of ibuprofen for PDA and their clinical and economic consequences. The course regimen of either formulation was an initial 10 mg/kg followed by 5 mg/kg at 24- and 48-h intervals. Clinical and resource utilization data were extracted from Cerner medical database, from 2014 through 2018, at the tertiary neonatal intensive care unit setting in Qatar. The primary outcome measures were the rate of successful closure based on the ductal diameter measure after the first course of treatment and the overall direct medical cost of PDA management. A population of 118 neonates was required for results with 80% power and 0.05 significance. Sensitivity analyses involving unit costs and a subgroup analysis based on gestational age and birth weight, added to a second-order probabilistic analysis of all model inputs, were performed. Findings: Forty infants were available for inclusion in the oral ibuprofen study group, not achieving the desired sample size, with successful PDA closure reported in 64% of cases compared with a reduced success of 36% with intravenous ibuprofen (n = 59) (risk ratio = 0.56; 95% CI, 0.32–0.97; P = 0.04), which was associated with economic advantage to oral ibuprofen. The probabilistic analysis illustrated that oral ibuprofen costs less than intravenous ibuprofen in 72% of patient cases, with QAR 48,751 (US $13,356) (95$13,014–$13,699) in mean savings. Sensitivity analyses confirmed the robustness of study conclusions and found that the rate of closure success versus failure was the most influential on results, followed by the occurrence of adverse drug events with both intravenous and oral ibuprofen. Although both ibuprofen formulations had similar safety profiles (P = 0.16), the intravenous formulation was associated with a larger number of adverse drug effects. Implications: This is the first cost-effectiveness evaluation of oral versus intravenous formulations of ibuprofen among infants with PDA. The oral ibuprofen might be associated with an enhanced ductal closure at a considerably lower cost. The study results support recent trends in neonatal intensive care unit practices in favor of the oral administration of ibuprofen.This work was supported by grant MRC-01-18-385 from the Medical Research Center, Hamad Medical Corporation, Qatar
