Diagnostic accuracy of pancreatic stone protein in patients with sepsis: a systematic review and meta-analysis.

BACKGROUND: Sepsis is a common syndrome of multiorgan system dysfunction secondary to the dysregulated inflammatory response to infection. The role of pancreatic stone protein (PSP) in diagnosing sepsis has been investigated in previous studies. The meta-analysis aimed to comprehensively investigate the diagnostic value of PSP in identifying sepsis. METHODS: PubMed, Web of Science, Embase, Cochrane Library, and China National Knowledge Infrastructure (CNKI), were systematically searched. Studies investigating the diagnostic performance of PSP were included. Pooled sensitivity, specificity, positive Likelihood Ratio (+ LR) and negative Likelihood Ratio (-LR), diagnostic odds ratio (DOR), and area under the curve (AUC) of summary receiver operating characteristic (SROC) were calculated. RESULTS: The sensitivity of PSP was 0.88 (95% CI: 0.77-0.94), and the pooled specificity was 0.78 (95% CI: 0.65-0.87). Pooled + LR, -LR, and DOR were 4.1 (2.3, 7.3), 0.16 (0.07, 0.34), and 26 (7, 98). The AUC value for the SROC of PSP was 0.90 (0.87, 0.92). The pooled sensitivity, specificity, + LR and - LR, and DOR for PSP among neonates were 0.91 (95% CI: 0.84, 0.96), 0.66 (95% CI: 0.58, 0.74), 3.97 (95% CI: 0.53, 29.58), 0.13 (95% CI: 0.02, 1.00), and 31.27 (95% CI: 0.97, 1004.60). CONCLUSIONS: This study indicates that PSP demonstrated favorable diagnostic accuracy in detecting sepsis. Well-designed studies are warranted to ascertain the value of PSP measurement to guide early empirical antibiotic treatment, particularly in neonates.

The complete chloroplast genome of Dryopteris crassirhizoma Nakai.

Dryopteris crassirhizoma Nakai is a fern plant with important evolutionary and medicinal values. Herein, we assembled the complete chloroplast genome of D. crassirhizoma by next-generation sequencing technology. The complete chloroplast genome of D. crassirhizoma was 153,355 bp in length, and the GC content was 42.86%; the genome consisted of a pair of inverted repeats (IRs, 23,470 bp), a small single copy region (SSC, 21,570 bp) and a large single copy region (LSC, 84,854 bp). The genome contained 111 genes, namely, 73 protein-coding genes, 34 tRNA genes and four rRNA genes. The phylogenetic analysis suggested that both D. crassirhizoma and D. decipiens from Dryopteridaceae were most closely related to Lepisorus clathratus from Polypodiaceae.

Characterization of the complete chloroplast genome of Corydalis bungeana Turcz.

Corydalis bungeana Turcz. is a perennial herb belonging to the family Papaveraceae. Its chloroplast genome was sequenced and characterized. The cp genome of C. bungeana is 167,629 bp long with a GC content of 36.52%. A total of 144 genes were identified in this cp genome, including 79 protein-coding genes, 31 tRNAs and four rRNAs. A phylogenetic tree based on the complete nucleic acid sequence indicated that C. bungeana was classified into Corydaleae and had a close relationship with Lamprocapnos spectabilis.

Association between the use of antibiotics during pregnancy and obesity in 5-year-old children.

BACKGROUND: Obesity is an epidemic that must arouse our attention. The purpose of this research is to investigate the relationship between antibiotic use during pregnancy and childhood obesity in 5-year-old Chinese children. METHODS: A total of 132 5-year-old children born in our hospital from January 2014 to January 2016 were included. The children's genders, nationalities, chronic diseases, and other factors were collected as adjusted covariates. We also collected the pre-pregnancy body mass indexes (BMIs) of pregnant women, diagnosis of diabetes mellitus or gestational diabetes mellitus (GDM), maternal smoking, mode of delivery (cesarean section and vaginal delivery), and weight gain during pregnancy, which may affect childhood obesity. A linear mixed effect regression model was used to test the correlation between antibiotic use during pregnancy and the BMI of 5-year-old children, and a logistic mixed effect regression model was used to evaluate the correlation between antibiotic use during pregnancy and obesity outcome. RESULTS: When adjusted for the child's gender, birth weight, cesarean section, chronic diseases, maternal smoking during pregnancy, pre-pregnancy BMI, diagnosis of diabetes or GDM, mode of delivery (cesarean section and vaginal delivery), and weight gain during pregnancy (Model 3), antibiotic use during pregnancy was positively correlated with the BMI of 5-year-old children (ß=0.01, 95% CI: 0.01-0.03, P=0.04). Antibiotic use during pregnancy increased the risk of obesity by 4% in 5-year-old children (OR =1.04, 95% CI: 1.01-1.16, P=0.02). CONCLUSIONS: The use of antibiotics during pregnancy is positively correlated with the risk of obesity in 5-year-old children. KEYWORDS: Antibiotics; pregnancy; obesity; children.
