Falling population incidence of eclampsia; A case-control study of short term outcome

Objective.To clarify the prevalence, risk factors, outcome, and outcome-related factors of hemophagocytic lymphohistiocytosis (HLH) in patients with dermatomyositis (DM), polymyositis (PM), or clinically amyopathic dermatomyositis (CADM).Methods.Data of patients with DM, PM, or CADM who were admitted to the First Affiliated Hospital of Zhejiang University from February 2011 to February 2019 were retrospectively collected. Patients diagnosed with HLH constituted the case group. A 1:4 case-control study was performed to identify risk factors for HLH in patients with DM, PM, or CADM through comparison, univariate, and multivariate logistic regression analysis. Intragroup comparison was made among patients with HLH to identify factors influencing unfavorable short-term outcome.Results.HLH was a rare (4.2%) but fatal (77.8%) complication in patients with DM, PM, or CADM. The retrospective case-control study revealed that higher on-admission disease activity (p = 0.008), acute exacerbation of interstitial lung disease (AE-ILD, p = 0.002), and infection (p = 0.002) were risk factors for complication of HLH in patients with DM, PM, or CADM. The following intragroup comparison showed that higher on-admission disease activity (p = 0.035) and diagnosis of CADM (p = 0.039) might influence the short-term outcome of patients with HLH. However, no risk factor was identified after false discovery rate correction.Conclusion.In this study, secondary HLH was a fatal complication, with higher on-admission disease activity, AE-ILD, and infection working as risk factors. The underlying role of infection and autoimmune abnormality in HLH in connective tissue disease was subsequently noted. Clinical factors influencing the short-term outcome of patients with secondary HLH require further study.

Abstract Background: To assess the influence of labor induction on the intrapartum maternal fever in epidural labor analgesia and to determine its association with intrapartum fever.Methods: A retrospective case-control study was performed during 2016–2018 in a first-class tertiary hospital. All patients who received epidural labor analgesia were allocated into either case (parturients who received labor induction and had intrapartum fever) or control (parturients who did not receive labor induction but had intrapartum fever) groups. Maternal demographic and intrapartum data, epidural infusions records, and neonatal short-term outcome were studied.Results: A total of 710 epidural labor analgesia occurred during the study period and 119 (16.76%) women had intrapartum fever. Intrapartum fever occurred in 66 (25.68%) women who received labor induction and in 53 (11.70%) who did not. After correction for confounding factors, labor induction (OR 2.818, 95% CI, 1.778–4.467, P<0.001), number of vaginal examinations (OR 1.242, 95% CI, 1.048–1.471, P=0.012), baseline maternal temperature (OR 6.702, 95% CI, 2.065–21.755, P=0.002), admission white blood cell count (OR 1.171, 95% CI, 1.052–1.303, P=0.004), and neonatal birth weight (OR 3.015, 95% CI, 1.739–5.227, P<0.001) were risk factors for intrapartum maternal fever during epidural labor analgesia.Conclusion: Labor induction was significantly associated with an increased risk of intrapartum maternal fever during epidural labor analgesia.

Objective Low birth weight (LBW) infants (<2,500 g) continued to be a global health problem because of the associated short- and long-term adverse outcomes. The study aimed to determine the prevalence, risk factors, and short-term outcomes of term LBW infants Study Design A prospective and case–control study. All infants born consecutively from September 1, 2018 to August 31, 2019 were included. Cases, term LBW infants, were 1:1 matched to controls, appropriate for gestational age (AGA) term infants. Major congenital or chromosomal anomalies and multiple pregnancies were excluded. Results The prevalence of term LBW in the studied period was 4.8%. Mothers of term LBW infants had significantly lower body mass index (p = 0.05), gained less weight (p = 0.01), had a history of previous LBW (p = 0.01), and lower monthly income (p = 0.04) compared with mothers of term AGA infants even after adjustment for confounders. A nonsignificant higher number of term LBW infants needed NICU admission, while their need for phototherapy was deemed significant. Conclusion We identified nutritional and socioeconomic maternal factors that are significantly associated with LBW infants and should be targeted during antenatal visits to improve neonatal outcomes.
