RESUMO

PURPOSE OF REVIEW: Pregnancy-induced preeclampsia is a severe pregnancy complication and preeclampsia has been associated with an increased risk of chronic hypertension for offspring. However, the magnitude of the overall effect of exposure to preeclampsia in pregnancy on blood pressure (BP) in offspring is unknown. This systematic review and meta-analysis was sought to systematically assess the effects of preeclampsia on the BP of the offspring. RECENT FINDINGS: Of 2550 publications identified, 23 studies were included. The meta-analysis indicated that preeclampsia increases the potential risk of hypertension in offspring. Systolic blood pressure (SBP) was 2.0 mm Hg (95% CI: 1.2, 2.8) and diastolic blood pressure (DBP) was 1.4 mm Hg (95% CI: 0.9, 1.9) higher in offspring exposed to pre-eclampsia in utero, compared to those born to normotensive mothers. The correlations were similar in stratified analyses of children and adolescents by sex, geographic area, ages, and gestational age. During childhood and young adulthood, the offspring of pregnant women with preeclampsia are at an increased risk of high BP. It is crucial to monitor their BP.

RESUMO

BACKGROUND: Exposure to particulate matter (PM) has been found to be associated with impaired cognitive function. However, limited evidence is available on the relationship between PM exposure in the prenatal period and toddler executive function (EF), and the potential influence of breastfeeding. METHODS: The study included 1106 mother-toddler pairs recruited between 2015 and 2019. We assessed mothers' PM1, PM2.5, and PM10 prenatal exposure with a satellite-based dataset at a 1 × 1 km spatial resolution and assigned to participants based on residential addresses. Toddler EF was measured using the Behavior Rating Inventory of Executive Function for Preschoolers (BRIEF-P) questionnaire, higher BRIEF-P scores indicated poorer EF in toddlers. We determined the associations of PM exposure during pregnancy with BRIEF-P scores using multiple linear regression models. RESULTS: In the first trimester, a 10 µg/m3 increase of PM was associated with 1.49 (95% confidence interval [CI]: 0.14-2.83; PM1), 0.68 (95% CI: 0.10-1.26; PM2.5), and 0.63 (95% CI: 0.07-1.20; PM10) elevated toddler global executive composite index scores, respectively. In the stratified analysis, a 10 µg/m3 increase in first trimester PM1 exposure was related to 0.54 (95% CI: 0.19-0.89) higher inhibition scores in toddlers who received complementary breastfeeding for less than six months and -0.15 (95% CI: 0.81-0.51) higher inhibition scores in toddlers who received complementary breastfeeding for six months or more (P for interaction: 0.046). Additionally, a 10 µg/m3 increment in first trimester PM1 exposure was related to 0.36 (95% CI: 0.13-0.59) higher emotional control scores in toddlers who received breastfeeding for less than 12 months and -0.54 (95% CI: 1.25-0.18) higher inhibition scores in toddlers who received breastfeeding for no less than 12 months (P for interaction: 0.043). CONCLUSIONS: PM exposure during the first trimester, especially PM1, has been linked to lower toddler EF performance in toddlers; feeding with breast milk may be a potential protective measure.

RESUMO

BACKGROUND: Outdoor artificial light at night (ALAN) has been linked to an elevated risk of diabetes, but the available literature on the relationships between ALAN and glucose homeostasis in pregnancy is limited. METHODS: A prospective cohort study of 6730 pregnant women was conducted in Hefei, China. Outdoor ALAN exposure was estimated using satellite data with individual addresses at a spatial resolution of approximately 1 km, and the average ALAN intensity was calculated. Gestational diabetes mellitus (GDM) was diagnosed based on a standard 75-g oral glucose tolerance test. Multivariable linear regression and logistic regression were used to estimate the relationships between ALAN and glucose homeostasis. RESULTS: Outdoor ALAN was associated with elevated glucose homeostasis markers in the first trimester, but not GDM risk. An increase in the interquartile range of outdoor ALAN values was related to a 0.02 (95% confidence interval [CI]: 0.00, 0.03) mmol/L higher fasting plasma glucose, a 0.42 (95% CI: 0.30, 0.54) µU/mL increase in insulin and a 0.09 (95% CI: 0.07, 0.12) increase in homeostatic model assessment of insulin resistance (HOMA-IR) during the first trimester. Subgroup analyses showed that the associations between outdoor ALAN exposure and fasting plasma glucose, insulin, and HOMA-IR were more pronounced among pregnant women who conceived in summer and autumn. CONCLUSIONS: The results provided evidence that brighter outdoor ALAN in the first trimester was related to elevated glucose intolerance in pregnancy, especially in pregnant women conceived in summer and autumn, and effective strategies are needed to prevent and manage light pollution.

RESUMO

BACKGROUND: Particulate matter (PM) exposure during pregnancy may increase cardiovascular risk (CVR). However, the specific time windows of exposure contributing to this association and the potential biological mechanisms underlying it remain unclear. OBJECTIVE: To determine the sensitive time window for CVR related to PM exposure. We investigated whether levels of inflammatory biomarkers mediate the relationship between PM exposure and CVR, and examined the potential impact of an anti-inflammatory diet on this association. METHODS: From 2015 to 2021, 9294 pregnant women from three Hefei hospitals were included. We used a 1 × 1 km satellite dataset to assess PM1, PM2.5, and PM10 exposure. High-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) were measured as inflammatory biomarkers. The empirical dietary inflammatory pattern (EDIP) score, based on a validated food frequency questionnaire. The CVR score was calculated using five clinical metrics based on American Heart Association criteria. RESULTS: We found a significant association between PM exposure and increased CVR score, especially during the 2nd to 8th weeks of the first trimester. For every increase of 10-µg/m3 of PM1, PM2.5, and PM10, there was an associated increase in CVR of 0.51 (95%CI: 0.21, 082), 0.25 (95% CI: 0.11 to 0.39), and 0.29 (95% CI: 0.09 to 0.37), respectively. Mediation analysis revealed that the proportion of the association between PM1, PM2.5, and PM10 exposure and CVR mediated by inflammatory biomarkers was 24.3%, 22.4%, and 20.1%, respectively. Stratified analyses showed no positive correlation between PM exposure and CVR in the anti-inflammatory diet (low EDIP) group. The ß coefficients were 0.52 for PM1 (95% CI: -0.06 to 1.11), 0.31 for PM2.5 (95% CI: -0.04 to 0.79), and 0.25 for PM10 (95% CI: -0.03 to 0.54). CONCLUSIONS: PM exposure, particularly during weeks 2-8 of pregnancy, correlates with CVR, partly mediated by levels of inflammatory biomarkers. An anti-inflammatory diet mitigates CVR associated with PM exposure.

RESUMO

BACKGROUND: Regarding the association between the sensitive time-windows of air pollution (AP) exposure and gestational diabetes mellitus (GDM), epidemiological findings are inconsistent. The dietary inflammatory potential has been implicated in the development of GDM, but it is unclear whether an anti-inflammatory diet during pregnancy reduces the association between AP and GDM. OBJECTIVE: We aimed to characterize the sensitive time-windows of AP to GDM risk. Further, to verify whether a maternal anti-inflammatory diet can reduce the risk of AP-induced GDM, by inhibiting inflammation. METHODS: A total of 8495 pregnant women were included between 2015 and 2021 in the Maternal & Infants Health in Hefei study. Weekly mean AP exposure to fine particles (PM2.5 and PM10), SO2, and NO2 was estimated from the data of Hefei City Ecology and Environment Bureau. High-sensitivity C-reactive protein (hs-CRP) concentrations were measured to evaluate systemic inflammation. The empirical dietary inflammatory pattern (EDIP) score based on a validated food frequency questionnaire was used to assess the dietary inflammatory potential of pregnant women. Logistic regression models with distributed lags were used to identify the sensitive time-window for the effect of AP on GDM. Mediation analysis estimated the mediated effect of hs-CRP, linking AP with GDM. Stratified analysis was used to investigate the potential effect of anti-inflammatory diet on GDM risk. RESULTS: The increased risks of GDM were found to be positively associated with exposure to PM2.5 (OR = 1.11, 95% CI:1.07-1.15), PM10 (OR = 1.12, 95% CI:1.09-1.16), and SO2 (OR = 1.42, 95% CI:1.25-1.60) by distributed lag models, and the critical exposure windows were 21st to 28th weeks of preconception. The proportion of association between PM2.5, PM10, and SO2 with GDM mediated by hs-CRP was 25.9%, 21.1%, and 19.4%, respectively, according to mediation analysis. In the stratified analyses by EDIP, the association between AP and GDM was not statistically significant among women those with anti-inflammatory diets. CONCLUSIONS: Exposure to AP, especially in 21st to 28th week of preconception, is associated with risk of GDM, which is partly mediated by hs-CRP. Adherence to the anti-inflammatory dietary pattern may reduce the risk of AP-induced GDM.

RESUMO

BACKGROUND: We aimed to explore the relationship between body mass index (BMI) and body weight perception (BWP) with suicidal behaviors among mainland Chinese adolescents. METHODS: A nationally representative sample (N = 10 110) of Chinese adolescents was assessed in this study. Suicidal behaviors (ideation, plan and attempt) were evaluated by four self-reported questions. Generalized linear mixed model was used to estimate the adjusted odds ratios (ORs) for the association between BWP/BMI with suicidal behaviors. RESULTS: The prevalence of suicidal ideation, suicidal plan and suicidal attempt was 12, 5 and 2.1%, respectively. After adjusting potential covariates, perceiving oneself as obese was significantly associated with increased risks of suicidal ideation (OR: 2.4, 95% confidence intervals, CI: 1.6-4.0, P = 0.001), suicidal plan (OR: 3.1, 95% CI: 1.5-6.3, P = 0.002) and suicidal attempt (OR: 3.7, 95% CI: 1.5-9.1, P = 0.001) compared with perceiving as normal weight among male adolescents; the effect attenuated to null among female adolescents. Perceiving oneself as underweight and overweight both exhibited significant adverse effect on suicidal behaviors (only suicidal ideation and suicidal plan) compared with perceiving oneself as normal weight among male adolescents, but not among female adolescents. The actual measured BMI was not significantly associated with suicidal behaviors among neither gender. CONCLUSIONS: Self-perception of their body image rather than actual measured weight may have a gender-specific adverse effect on suicidal behaviors among Chinese adolescents.

RESUMO

BACKGROUND: A key component of the 2009 medical reform in China was the change to family doctor (FD) policy practice. However, this led to an increased workload for primary health-care workers (PHCWs) at community health service centres. Their increasing workload may play a significant role in affecting PHCWs' health. METHODS: A questionnaire survey was conducted in Hongkou district of Shanghai amongst PHCWs including family doctors (FDs), family nurses (FNs), public health doctors (PHDs), and other PHCWs in early 2019. Ordered logistic regression models (Models 1 to 3) were performed to explore the differing health status amongst PHCWs, and their respective influential factors were also tested (Models 4 to 7). RESULTS: Five hundred sixty-two valid questionnaires were collected with a response rate of 96.4%. Other PHCWs' (OR = 2.03; 95% CI: 1.163-3.560) and FNs' (OR = 1.98; 95% CI: 1.136-3.452) self-rated health (SRH) were significantly better than that of FDs. In terms of FNs, the OR of SRH for those who strongly perceived the extra workload brought by FD-contracted services was only 12.0% (95% CI: 0.018-0.815) of that of the no-pressure group. Similarly, FNs with stronger work pressure had worse SRH, i.e., compared with "no" pressure, the SRH ORs for "neutral," "strong," and "very strong" evaluations of work pressure were 0.002 (95% CI: 0.000-0.055), 0.001 (95% CI: 0.000-0.033), and 0.000 (95% CI: 0.000-0.006), respectively. Information technology (IT) systems and performance incentives were suggested to improve SRH for FNs, while the former was found to be negatively correlated with other PHCWs. After one unit increase in the PHDs' team/department support, their OR was 10.7 times (95% CI: 1.700-67.352) higher. In addition, policy support had a negative effect on SRH for PHDs. The OR of "good" assessments of cultural environments was 25.98 times (95% CI: 1.391-485.186) higher than that of "very poor" for Other PHCWs. CONCLUSIONS: The influences of FD policy practice on FNs' SRH were the most significant amongst PHCWs, rather than FDs' as expected. The significant factors of SRH were varied over different occupational categories, that is team/department support and policy support (though negative) for PHDs, IT system and incentive for FNs, facility and equipment for FDs, and culture environment for other PHCWs respectively.

RESUMO

Osteogenesis of mesenchymal stem cells to differentiate between bone marrow by multiple signaling pathways that control, directly or indirectly affect small related transcription factor 2 (runt-related transcription factor 2, Runx2) and osteoblast specific transcription factor (osterix, Osx), the expression of osteogenesis key transcription factors, such as in the development and regeneration of the bone, bone repair has played a key role in the process of reconstruction. These pathways play their mechanism of action, but also intertwined associated constitute a complex signal transduction network, but due to the limitations of research methods, the osteogenic differentiation related signaling pathways of the specific mechanism is still unclear, if you can clarify these different signaling pathways play to the role of their relevant mechanism and the relationship between various pathways and the mechanism study of osteogenesis differentiation is of great importance. This article will review the progress of various signaling pathways in the regulation of osteogenic differentiation of bone marrow mesenchymal stem cells.

RESUMO

For screening the active phloroglucinols on influenza virus (H5N1) from Dryopteris crassirhizoma NaKai, a database was established including twenty-three phloroglucinols that had been isolated from Dryopteris crassirhizoma. Their inhibitory effect on the neuraminidase (NA) of influenza virus H5N1 was screened by molecular docking. As a result, three candidates were selected. The rhizomes of D. crassirhizoma were subjected to isolation and purification processes to obtain the inhibitor candidates. Thirteen phloroglucinols were obtained, including three selected candidates and two new phloroglucinols. The five phloroglucinols were investigated for their inhibitory activity on NA in vitro. The results showed that dryocrassin ABBA and filixic acid ABA exhibited inhibitory effects on NA with IC50 as 18.59 ± 4.53 and 29.57 ± 2.48 µM, respectively, and the other three phloroglucinols showed moderate inhibitory activity. Moreover, the anti-influenza virus (H5N1) activity and cytotoxicity of dryocrassin ABBA and filixic acid ABA were tested on Madin-Darby canine kidney (MDCK) cells with the cell counting kit-8 (CCK8) method. The results confirmed that dryocrassin ABBA exhibited an inhibitory activity with low cytotoxicity (TC50 > 400 µM) against influenza virus (H5N1) which will have to be investigated in further detail. In conclusion, phloroglucinols from D. crassirhizoma were shown to have anti-influenza virus activity, and especially dryocrassin ABBA, one of the phloroglucinols, may have the potential to control influenza virus (H5N1) infection.

RESUMO

BACKGROUND: The survival following transarterial chemoembolization (TACE) alone is still low in unresectable hepatocellular carcinoma (HCC) with almost patients developing disease progression after treatment. There is need to investigate additional therapeutic options that would intensify the initial response to TACE. The present study was to retrospectively compare the outcome and evaluate the prognostic factors of stereotactic body radiation therapy (SBRT) alone or as an adjunct to transarterial embolization (TAE) or TACE in the treatment of HCC >5 cm. METHODS: From January 2011 to April 2015, 77 patients received SBRT followed by TAE or TACE (TAE/TACE + SBRT group) and 50 patients received SBRT alone (SBRT group). The dose of SBRT was 30-50 Gy which was prescribed in 3-5 fractions. Eligibility criteria were: a longest tumor diameter >5.0 cm and Child-Turcotte-Pugh (CTP) Class A or B. Exclusion criteria included tumor thrombus, lymph node involvement and extrahepatic metastasis. RESULTS: The median follow-up period was 20.5 months. Median tumor size was 8.5 cm (range, 5.1-21.0 cm). Median overall survival (OS) in the TAE/TACE + SBRT group was 42.0 months versus 21.0 months in the SBRT group. The 1-, 3- and 5-year OS was 75.5, 50.8, and 46.9 % in the TAE/TACE + SBRT group and was 62.4, 32.9, and 32.9 % in the SBRT group, respectively (P = 0.047). The 1-, 3- and 5-year distant metastasis-free survival (DMFS) was 66.3, 44.3, and 40.6 % in the TAE/TACE + SBRT group and was 56.8, 26.1, and 17.4 % in the SBRT group, respectively (P = 0.049). The progression-free survival (PFS) and local relapse-free survival (LRFS) were not significantly different between the two groups. In the entire patient population, a biologically effective dose (BED10) ≥100 Gy and an equivalent dose in 2 Gy fractions (EQD2) ≥74 Gy were significant prognostic factors for OS, PFS, LRFS and DMFS. CONCLUSIONS: SBRT combined with TAE/TACE may be an effective complementary treatment approach for HCC >5 cm in diameter. BED10 ≥100 Gy and EQD2 ≥74 Gy should receive more attention when the SBRT plan is designed.

RESUMO

The content changes of chemical components in different phenological phase of the cultivated Polygala tenuifolia is one of the important factors for determination of the best harvest time in the production practice. In this study, the digital gene expression (DGE) profiles of the cultivated P. tenuifolia were analyzed in different phenological phase (flowering fruit bearing stage, wilting stage, dormancy stage). The differentially expressed genes were found in the biosynthesis of chemical composition in P. tenuifolia, and the representational ones were validated by RT-q PCR. Then, the key enzymes(CYP450s and UGTs) involved in the downstream of the triterpenoid saponins biosynthesis pathway in P. tenuifolia were predicted through the correlation analysis of gene expression. The number of down-regulated genes was more than that of up-regulated in P. tenuifolia from flowering fruit bearing stage to dormancy stage. Six differentially expressed genes (HMGS, PMK, FPPS, SQS, SE, ß-AS) and five (PAL, C4 H, 4CL, CAD, peroxidase) were annotated to the triterpenoid saponins and phenylpropanoid biosynthesis pathway in P. tenuifolia, respectively. Compared to wilting and dormancy stages, the saponins, xanthones, and lignins were largely synthesized at the flowering fruit bearing stage of P. tenuifolia. Furthermore, UGT83A1, CYP716B1, CYP98A3, CYP86B1, and CYP94A1 may be the part of key enzymes in the downstream of the triterpenoid saponins biosynthesis pathway in P. tenuifolia. This study provides evidence to support the correctness of traditional harvest time of P. tenuifolia at the level of transcription, and lays the scientific foundation for gene cloning and functional verification of CYP450 s and UGTs in the downstream of the triterpenoid saponins biosynthesis pathway in P. tenuifolia in the future.

RESUMO

Growth year is one of the important factors for the quality of Polygala tenufolia. In this study, primary metabolites and secondary metabolites were compared in 1, 2 and 3 years old P. tenufolia cultivated in Shaanxi Heyang. The samples were subjected to ultra-high performance liquid chromatography (UPLC)-quadrupole time-of-flight mass spectrometry (Q-TOF MS) and nuclear magnetic resonance (NMR) analysis, and the obtained data were analyzed using principal component analysis (PCA) and other statistical analysis methods. In addition, content and correlation of different metabolites were also calculated. The results showed no significance between main component contents in 2 year-old and 3 year-old P. Tenufolia, but 1 year-old was statistically different. The contents of primary metabolites, such as fructose, sucrose, and choline increased as time goes on, while glycine and raffinose decreased. The contents of secondary metabolites, such as onjisaponin Fg, polygalasaponin XXVIII, polygalasaponin XXXII increased, while polygalaxanthone III and parts of oligosaccharide multi-ester including tenuifoliose A, tenuifoliose C, tenuifoliose C2 and tenuifoliose H decreased with the extension of the growth years. Growth years has important impact on the quality of P. tenuifolia and the existing growing years of commodity P. tenuifolia have its scientific evidence. This study supplied a new method for the quality evaluation of Chinese medicinal materials.

RESUMO

OBJECTIVE: To isolate, identify and culture human spermatogonial stem cells (SSC) and then obtain purified and enriched human SSCs for research and application. METHODS: We detected the expression of CD90 in the human testis using the immunofluorescence technique and isolated human testicular spermatogenic cells by two-step enzymatic digestion, followed by differential plating and magnetic-activated cell sorting (MACS) with CD90 as an SSC marker. Then we identified the isolated CD90-positive spermatogenic cells by RT-PCR and immunocytochemistry, and meanwhile cocultured them with Sertoli cells in SG medium in vitro. RESULTS: The isolated CD90-positive cells showed a relatively homogeneous characteristic in size and morphology and expressed the genes specific for human SSCs, with high expressions (90.5%) of GFRA1, GPR125, and UCHL1. After coculture with Sertoli cells in the SG medium for 2 weeks, the isolated CD90-positive cells maintained a good activity. CONCLUSION: CD90 can be regarded as a speci- fic marker for human SSCs and used to obtain highly enriched human SSCs by differential plating and MACS. Furthermore, the isolated human SSCs can be cultured in SG medium in vitro.

RESUMO

OBJECTIVE: The chemical differences of Polygala tenuifolia varieties-JinYuan 1 (JY1), FenYuan 2 (FY2) and traditional FenYang (FY) were studied, in order to provide reference for the breeding of Polygala tenuifolia. METHODS: The samples of JY1, FY2 and FY were subjected to ultra-high performance liquid chromatography (UPLC) quadrupole time-of-flight mass spectrometry (Q-TOF MS) analysis. The obtained data were analyzed using Principal Component Analysis (PCA) and other statistical analysis methods, and differential metabolites were further figured out. RESULTS: Compared with FY,sucrose esters (such as sibiricoses A5 and tenuifoliside B) and oligosaccharides (such as tenuifoliose K) in JY1 and FY2 contributed more to the separation of Polygala tenuifolia varieties in the PCA score plot. Compared with JYl, The sugar esters (such as tenuifoliside B and tenuifoliside A) and oligosaccharides( such as tenuifoliose A) in the FY2 also contributed more to the separation of Polygala tenuifolia varieties in the PCA score plot. In addition, the relative contents of sibiricaxanthone A,3,6'-disinapoly sucrose and senegin III showed significant differences among FY, JY1 and FY2. CONCLUSION: As new Polygala tenuifolia varieties, JY1 and FY2 had certain differences and respective advantages on the chemical composition compared with FY,which could provide data support for the directional breeding of Polygala tenuifolia based on the contents of some active compounds.

RESUMO

AIM: To examine the change in Body Mass Index (BMI) and waist circumference (WC) among primary and secondary school students aged 7-18 in Anhui Province between 2005-2010. SUBJECTS AND METHODS: A total of 15 812 primary and secondary school students aged 7-18 were included in two national surveys on students' constitution and health in 2005 and 2010 in Anhui Province. Measurements of height, weight and WC were taken by trained investigators. BMI was calculated for each subject. RESULTS: The mean BMI and WC were significantly increased from 2005 to 2010. For boys, mean increases were 0.85 kg/m(2) and 2.01 cm or 0.08 and 0.34 SD score units, while for girls those were 0.39 kg/m(2) and 2.10 cm or 0.20 and 0.39 SD score units (all p < 0.001). The standard deviation scores for WC increased much more than for BMI (0.34 units vs 0.08 units for boys and 0.39 units vs 0.20 units for girls). CONCLUSIONS: The average value of BMI and WC among primary and secondary school students has increased dramatically from 2005 to 2010 in Anhui, China. Changes in WC have greatly exceeded those in BMI, showing that WC is a good proxy for central fatness rather than BMI.

RESUMO

The Mediterranean diet is a global, well-known healthy dietary pattern. This review aims to synthesize the existing evidence on the relationship between the maternal Mediterranean diet during pregnancy and perinatal outcomes, including randomized controlled trials (RCTs) and cohort studies. PubMed, Web of Science, and the Cochrane Library were searched from inception to 10 March, 2023, supplemented by manual screening. A random-effect model was used to estimate pooled sizes with 95% confidence intervals (CIs) for specific outcomes of interest. Data from 5 RCTs and 18 cohort studies with 107,355 pregnant participants were synthesized. In RCTs, it was observed that the maternal Mediterranean diet significantly reduced the incidence of gestational diabetes mellitus [odds ratio (OR), 0.56; 95% CI: 0.34, 0.93], as well as small for gestational age (0.55; 95% CI: 0.35, 0.88). In cohort studies, the highest adherence score to the maternal Mediterranean diet was inversely associated with a lower risk of various adverse pregnancy outcomes, including gestational diabetes mellitus (OR, 0.82; 95% CI: 0.67, 1.00), pregnancy-induced hypertension (0.73; 95% CI: 0.60, 0.89), pre-eclampsia (0.77; 95% CI: 0.64, 0.93), preterm delivery (0.67; 95% CI: 0.49, 0.91), low birth weight (0.70; 95% CI: 0.64, 0.78), intrauterine growth restriction (0.46; 95% CI: 0.23, 0.91), and increased gestational age at delivery (weighted mean difference, 0.11 wk; 95% CI: 0.03, 0.20). Meta-regression analyses did not identify the adjustment for confounders and geographical location as predictive factors for heterogeneity. The results suggest that adherence to the Mediterranean diet during pregnancy appears to be beneficial for perinatal outcomes. Future, larger, and higher-quality RCTs and cohort studies are warranted to confirm the present findings. PROSPERO registration no.: CRD42023406317.

RESUMO

CONTEXT: The putative association between proinflammatory and hyperinsulinemic dietary patterns and susceptibility to gestational diabetes mellitus (GDM) remains unclear. OBJECTIVE: We aimed to compare the risk associated with the Mediterranean diet, as well as insulinemic and proinflammatory dietary patterns, in relation to the occurrence of GDM, and evaluate their predictive value. METHODS: We prospectively followed 8, 495 women from the Maternal and Infant Health cohort in Hefei, China (2015-2021). Using a food frequency questionnaire, we calculated the Empirical Dietary Inflammatory Pattern (EDIP), the Empirical Dietary Index for Hyperinsulinemia (EDIH) score, and the Mediterranean diet (MD) score. GDM was diagnosed based on a 2-hour 75-gram oral glucose tolerance test conducted between 24 to 28 weeks of gestation. Logistic regression was used to estimate the risk of GDM, while Receiver Operating Characteristic (ROC) curves were constructed to evaluate the predictive performance of the empirical dietary index for GDM. RESULTS: Participants who followed hyperinsulinemic or proinflammatory dietary patterns to the greatest extent had a higher risk of developing GDM. The OR for the highest quartile compared to the lowest quartile were 1.39 (95% CI: 1.30-1.49) for EDIH and 2.40 (95% CI: 1.88-3.01) for EDIP. The OR for the lowest quartile compared to the highest quartile was 1.33 (95% CI:1.14-1.55)for MD. The ROC curve analysis indicated that the combination of EDIP and EDIH (AUC = 0.81, 95% CI: 0.78-0.82, P = 0.003) can effectively predict the occurrence of GDM. CONCLUSIONS: Utilizing both empirical dietary indexes, EDIP and EDIH, might offer a potentially more effective approach in preventing GDM when compared to solely focusing on adherence to the Mediterranean diet pattern.
