Objectives: Pre-pregnancy diet has an important role in preparing for healthy generation. However, evidence on this issue has been scarce. A scoping review synthesising current evidence will support the demand to map ‘what has been researched’ on pre-pregnancy diet and maternal and child health.Methods: Systematic search was performed using PICOS (Population, Intervention, Comparison, Outcomes, and Study design) framework in electronic databases. Articles were screened for eligibility, summarized, and the quality was assessed using the National Institute of Health assessment tool. The review structure complies with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guide.Results: Forty-two articles were included after full-text screening. Twenty-five studies were in high-income countries (HICs), six in each upper-middle income, five in lower-middle income countries (LMICs), and one in low-income countries (LIC). Based on the regions: North America (n=16), Europe (n=5), South America (n=4), Australia (n=4), Asia (n=5), Middle East (n=2), and sub-Saharan Africa (n=1). The two-most observed diet-related exposures were dietary pattern (n=17) and dietary quality (n=12). The most assessed outcome was gestational diabetes mellitus (n=28) and fetal and newborn anthropometry (n=7). The average quality score±standard deviation was 70±18%.Conclusions: Research related to pre-pregnancy diet is still concentrated in HICs. The context of diet may vary; therefore, future research is encouraged in LMICs and LICs context, and Mediterranean, South-East Asia, Pacific, and African regions. Some maternal and child nutrition-related morbidity, such as anemia and micronutrient deficiencies, have not been discussed. Research on these aspects will benefit to fill in the gaps related to pre-pregnancy diet and maternal and child health.

Background Sepsis is a leading cause of children’s mortality worldwide. Procalcitonin (PCT) is a widely used infection marker, but has limitations in terms of cost and availability. The neutrophil-lymphocyte count ratio (NLCR) is easy to perform, low-cost, and widely used as a diagnostic and prognostic marker of various inflammatory processes. Objective To investigate possible correlations of NLCR to PCT and Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score among pediatric sepsis patients. Method A retrospective study was conducted by reviewing the Pediatric Sepsis Registry at Dr. Hasan Sadikin General Hospital, Bandung, West Java, from January 2019–June 2020. We recorded patients’ characteristics, PELOD-2 score, NLCR, and PCT results. Correlation analysis was conducted using Spearman’s Rank test with significance value of P<0.05. Results Ninety patients were included in the study. Most patients were male (56.7%), under 2 years of age (57.8%), and had lower respiratory tract infection (67.8%) as the most common source of infection. The NLCR value had significant, positive correlations to PCT (r=0.642; P<0.001) and PELOD-2 score (r=0.233; P=0.027) in pediatric sepsis patients. Conclusion The NLCR is directly proportional to PCT in pediatric sepsis patients. This result suggents that NLCR may have a potential role as an alternative marker for sepsis in emergency setting.
