Abstract
The encoding of qubits in semiconductor spin carriers has been recognized as a promising approach to a commercial quantum computer that can be lithographically produced and integrated at scale1-10. However, the operation of the large number of qubits required for advantageous quantum applications11-13 will produce a thermal load exceeding the available cooling power of cryostats at millikelvin temperatures. As the scale-up accelerates, it becomes imperative to establish fault-tolerant operation above 1 K, at which the cooling power is orders of magnitude higher14-18. Here we tune up and operate spin qubits in silicon above 1 K, with fidelities in the range required for fault-tolerant operations at these temperatures19-21. We design an algorithmic initialization protocol to prepare a pure two-qubit state even when the thermal energy is substantially above the qubit energies and incorporate radiofrequency readout to achieve fidelities up to 99.34% for both readout and initialization. We also demonstrate single-qubit Clifford gate fidelities up to 99.85% and a two-qubit gate fidelity of 98.92%. These advances overcome the fundamental limitation that the thermal energy must be well below the qubit energies for the high-fidelity operation to be possible, surmounting a main obstacle in the pathway to scalable and fault-tolerant quantum computation.

Abstract
Objective: To analyze and compare the risk factors for hemorrhagic stroke and ischemic stroke and understand the exposure levels in population. Methods: A cohort study of risk factors of stroke was conducted in a rural community in Fengxian District of Shanghai in 2003, and the common risk factors of stroke were investigated at baseline survey, the cerebrovascular hemodynamics indexes were detected, the cerebrovascular function score was calculated according to the unified integral rule, and the incidence of stroke was observed in follow up. The risk factors for hemorrhagic stroke and ischemic stroke were analyzed by cohort study. The risk factors for two subtypes of stroke were compared. Result: A total of 10 565 participants were included in the study, with a mean follow-up period of (11.15±2.26) years, and 103 hemorrhagic stroke cases and 268 ischemic stroke cases were observed during follow-up period. The independent risk factors of hemorrhagic stroke included decreased cerebrovascular function score [hazard ratio (HR)=1.56, 95%CI: 1.23-1.98], history of alcohol consumption (HR=2.46, 95%CI: 1.39-4.34), hypertension (HR=1.75, 95%CI: 1.00-3.07) and older age (HR=1.07, 95%CI: 1.04-1.10). The independent risk factors of ischemic stroke included decreased cerebrovascular function score (HR=1.43, 95%CI: 1.25-1.65), smoking history (HR=1.52, 95%CI: 1.13-2.05), hypertension (HR=1.51, 95%CI: 1.10-2.07), family history of stroke (HR=1.89, 95%CI: 1.13-3.15), left ventricular hypertrophy (HR=1.74, 95%CI: 1.07-2.81) and older age (HR=1.07, 95%CI: 1.05-1.08). Conclusions: Decreased cerebrovascular function score, hypertension, and older age were common independent risk factors of both types of stroke, alcohol consumption history was an independent risk factor of hemorrhagic stroke, and smoking history, and family history of stroke and left ventricular hypertrophy were independent risk factors of ischemic stroke.

Abstract
Objective: To conduct a comparative analysis of the efficacy, safety, and cytokine changes associated with three distinct dose escalation regimens of allergen-specific immunotherapy (AIT), and to provide valuable insights into the implementation of safer and more effective accelerated immunotherapy in clinical practice. Methods: A prospective study of subcutaneous immunotherapy (SCIT) was conducted at Renmin Hospital of Wuhan University, involving patients with allergic rhinitis visited from 2019 to 2022. Participants were allocated to one of three treatment groups based on their preferences: conventional immunotherapy (CIT, 23 cases), cluster immunotherapy (CLIT, 25 cases), or rush immunotherapy (RIT, 18 cases). The RIT group received a single subcutaneous injection of 150 mg of omalizumab one week before commencing treatment. Subjective evaluation indices, including the Combined Symptom and Medication Score (CSMS), Visual Analogue Scale (VAS), and single symptom score, were recorded alongside objective evaluation indices (e.g., sIgE, tIgE, Th1/2 and Th17 cytokines) and adverse reactions. Assessments were conducted at baseline, and at 1, 7, and 15 weeks after treatment. SPSS 22.0 software was used for data processing and analysis. Results: The study included a total of 66 patients, comprising 37 males and 29 females, who completed the treatment regimen. In all three groups, CSMS and VAS scores showed significant reductions at 1, 7, and 15 weeks post-treatment (all P<0.05). Notably, the RIT group demonstrated a significantly lower VAS score (4.33±0.94) compared to the CIT (9.48±1.37) and CLIT (9.44±1.33) groups at 1 week post-treatment (P<0.05). Additionally, the RIT group (0.62±0.23) exhibited a lower CSMS score than the CIT (1.54±0.21) and CLIT (1.06±0.22) groups at 15 weeks post-treatment (P<0.05). Furthermore, at the point of reaching the maintenance dose, the RIT group (0.61±0.20) demonstrated superior improvement in nasal itching symptoms compared to the CIT (1.78±0.38) and CLIT groups (1.56±0.32), with P<0.05. The incidence of local adverse reactions in the RIT group (36/11.76%) was lower than that in the CIT (69/20.00%) and CLIT groups (62/16.53%), with P<0.05. Notably, none of the three groups reported grade 3/4 systemic adverse reactions, and there was no statistically significant difference in systemic adverse reactions among the three groups. Following treatment, IL-4, IL-5, IL-6, IL-17, sIgE, sIgE/tIgE, and Eos% exhibited varying degrees of decrease in all three groups, whereas IL-10, TNF, and IFN-γ did not show significant changes. Conclusions: All three distinct dose escalation regimens of SCIT demonstrated substantial clinical efficacy. Of note, the approach of combining a single injection of omalizumab with RIT significantly improved early-stage efficacy and exhibited the advantages of safety, effectiveness, and convenience, establishing it as a reliable immunotherapy method.

Abstract
The small size and excellent integrability of silicon metal-oxide-semiconductor (SiMOS) quantum dot spin qubits make them an attractive system for mass-manufacturable, scaled-up quantum processors. Furthermore, classical control electronics can be integrated on-chip, in-between the qubits, if an architecture with sparse arrays of qubits is chosen. In such an architecture qubits are either transported across the chip via shuttling or coupled via mediating quantum systems over short-to-intermediate distances. This paper investigates the charge and spin characteristics of an elongated quantum dot-a so-called jellybean quantum dot-for the prospects of acting as a qubit-qubit coupler. Charge transport, charge sensing, and magneto-spectroscopy measurements are performed on a SiMOS quantum dot device at mK temperature and compared to Hartree-Fock multi-electron simulations. At low electron occupancies where disorder effects and strong electron-electron interaction dominate over the electrostatic confinement potential, the data reveals the formation of three coupled dots, akin to a tunable, artificial molecule. One dot is formed centrally under the gate and two are formed at the edges. At high electron occupancies, these dots merge into one large dot with well-defined spin states, verifying that jellybean dots have the potential to be used as qubit couplers in future quantum computing architectures.

Abstract
AIMS To examine associations of assisted reproductive technology (ART) conception (vs. natural conception: NC) with offspring cardiometabolic health outcomes and whether these differ with age. METHODS AND RESULTS Differences in systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR), lipids, and hyperglycaemic/insulin resistance markers were examined using multiple linear regression models in 14 population-based birth cohorts in Europe, Australia, and Singapore, and results were combined using meta-analysis. Change in cardiometabolic outcomes from 2 to 26 years was examined using trajectory modelling of four cohorts with repeated measures. 35 938 (654 ART) offspring were included in the meta-analysis. Mean age ranged from 13 months to 27.4 years but was <10 years in 11/14 cohorts. Meta-analysis found no statistical difference (ART minus NC) in SBP (-0.53 mmHg; 95% CI:-1.59 to 0.53), DBP (-0.24 mmHg; -0.83 to 0.35), or HR (0.02 beat/min; -0.91 to 0.94). Total cholesterol (2.59%; 0.10-5.07), HDL cholesterol (4.16%; 2.52-5.81), LDL cholesterol (4.95%; 0.47-9.43) were statistically significantly higher in ART-conceived vs. NC offspring. No statistical difference was seen for triglycerides (TG), glucose, insulin, and glycated haemoglobin. Long-term follow-up of 17 244 (244 ART) births identified statistically significant associations between ART and lower predicted SBP/DBP in childhood, and subtle trajectories to higher SBP and TG in young adulthood; however, most differences were not statistically significant. CONCLUSION These findings of small and statistically non-significant differences in offspring cardiometabolic outcomes should reassure people receiving ART. Longer-term follow-up is warranted to investigate changes over adulthood in the risks of hypertension, dyslipidaemia, and preclinical and clinical cardiovascular disease.

Abstract
Objective: To preliminarily evaluate the safety and efficacy of shunt-related interventional therapy accompanied with spontaneous portosystemic shunts (SPSS) in patients with hepatic encephalopathy (HE). Methods: Case data on six patients who underwent interventional therapy accompanied by SPSS for HE from January 2017 to March 2021 were collected to evaluate the efficacy and postoperative complications. Results: All six patients underwent SPSS. Four patients had hepatitis B cirrhosis; one had alcoholic cirrhosis; and one had hepatic arterioportal fistula-induced portal hypertension. Child-Pugh liver function scores were C and B in three and three cases, respectively. The SPSS type was gastrorenal shunt in two cases; portal-thoracic-azygos venous in two cases; portal-umbilical-iliac venous in one case; and portal-splenic venous - inferior vena cava in one case. Two of them had previously had a transjugular intrahepatic portosystemic shunt (TIPS), and there were SPSS prior to TIPS. Five cases (5/6) successfully underwent shunt embolization, and one case (1/6) underwent stent implantation for flow restriction (portal-umbilical-iliac vein). The technical success rate was 100%. HE did not recur during hospitalization or the three-month follow-up period. However, one case had a recurrence of HE within a year after surgery and was treated symptomatically, while another experienced gastrointestinal bleeding a year after surgery.. Conclusion: SPSS embolization or flow restriction is effective and safe for improving HE patients' symptoms.

Abstract
Once called a 'classically non-describable two-valuedness' by Pauli, the electron spin forms a qubit that is naturally robust to electric fluctuations. Paradoxically, a common control strategy is the integration of micromagnets to enhance the coupling between spins and electric fields, which, in turn, hampers noise immunity and adds architectural complexity. Here we exploit a switchable interaction between spins and orbital motion of electrons in silicon quantum dots, without a micromagnet. The weak effects of relativistic spin-orbit interaction in silicon are enhanced, leading to a speed up in Rabi frequency by a factor of up to 650 by controlling the energy quantization of electrons in the nanostructure. Fast electrical control is demonstrated in multiple devices and electronic configurations. Using the electrical drive, we achieve a coherence time T2,Hahn ≈ 50 μs, fast single-qubit gates with Tπ/2 = 3 ns and gate fidelities of 99.93%, probed by randomized benchmarking. High-performance all-electrical control improves the prospects for scalable silicon quantum computing.

Background
Prosthetic valve endocarditis (PVE) is a rare but serious complication following valvular heart surgery for which preventive strategies remain unknown. Recent epidemiological evidence suggests that statins may reduce the risk of infections and infection-related complications.
Purpose
We aim to assess the association between statin use and the risk of prosthetic valve endocarditis in patients undergoing valvular heart surgery.
Methods
In all patients undergoing valvular heart surgery in Hong Kong between 2010 and 2021, statin use was ascertained by ≥14-day consecutive filled prescriptions after surgery. Stepwise Poisson regression was applied to identify predictors of PVE. Baseline characteristics between statin nonusers (N = 1400) with statin users (N = 976) were balanced using the inverse probability of treatment weighting. Cox proportional-hazard models with competing risk regression were further performed to estimate the risk of PVE and cardiovascular mortality associated with statin use.
Results
Our study included 2376 patients; the mean age was 57.8±14.2 years, and 54.4% were males. Over a median follow-up of 5.5 years (interquartile range 2.8-8.6), PVE occurred in 93 patients (6.75 [95% CI 5.51-8.26] PVE events per 1000 person-years). PVE was associated with New York Heart Association Class (Relative Risk [RR] 1.22, 95% Confidence Interval [CI] 1.01-1.45; P = 0.035), prior infective endocarditis (RR 8.64, 95% CI 5.58-13.19; P < 0.001), and aortic valve replacement (RR 1.67, 95% CI 1.11-2.53; P = 0.014).
Compared with non-use, statin use was associated with a 47% lower risk of PVE incidence (multivariable-adjusted subdistribution hazard ratio [SHR] 0.53, 95% CI 0.33-0.83; P = 0.006) (Figure 1). This inverse association with the risk of PVE was duration dependent, with an adjusted SHR of 0.60 (95% CI 0.47-0.73; P < 0.001) per year of statin use. Results were consistent across subgroups of sex (male vs female), the number of valvular procedures (single vs multiple), and prosthesis type (mechanical vs biological), but not in groups aged ≤60 years or with prior infective endocarditis (Figure 2). Statin use was associated with a 45% decreased risk of cardiovascular death (SHR 0.55, 95% CI 0.36-0.84; P = 0.006).
Conclusions
In patients undergoing valvular surgery, post-operative statin use is associated with a lower risk of PVE. These results provide new avenues for preventing PVE and hence valve failure.

Background
Novel strategies to improve the long-term risk stratification of valvular surgery are urgently needed as a result of the increasing prevalence of valvular heart diseases globally.
Purpose
This study aimed to evaluate the prognostic implications of longitudinal assessment of inflammatory and nutritional status in patients undergoing valvular surgery.
Methods
1046 patients who underwent valvular surgery were stratified into three groups based on their inflammatory (neutrophil-to-lymphocyte ratio [NLR]) and nutritional status (prognostic nutritional index [PNI]): without inflammation and malnutrition (normal), inflammation or malnutrition alone (mild), and concomitant inflammation and malnutrition (severe). Optimal NLR and PNI thresholds for predicting all-cause mortality were determined using receiver-operating characteristic analysis. The endpoints were all-cause mortality, cardiovascular death and adverse events (composite of death and heart failure [HF] hospitalization).
Results
Over a median follow-up of 4.3 years (IQR: 2.6 to 6.4 years), 139 (13.3%) deaths and 148 (14.1%) HF hospitalizations occurred. Based on the optimal cut-off of NLR >4.06 (inflammation) and PNI <45.8 (malnutrition), 714 (68.3%), 214 (20.5%) and 118 (11.3%) patients were categorized into normal, mild and severe groups respectively. Compared with patients without inflammation and malnutrition, those with concomitant inflammation and malnutrition before surgery had the highest risk of all-cause mortality (hazard ratio [HR] 5.60, 95% confidence interval [CI] 3.66-8.57), cardiovascular death (subdistribution HR [SHR] 5.19, 95% CI 2.33-11.60) and adverse events (HR 3.14, 95% CI 2.25-4.38) (p<0.001 for all), adjusted for demographics, cardiovascular risk factors and diseases, medications, valvular surgeries and EuroSCORE II. Discriminatory improvement for predicting all-cause mortality was observed when baseline NLR and PNI were added to EuroSCORE II (C-statistic 0.77 vs 0.73, p=0.04; continuous net reclassification improvement [cNRI] 0.24, 95% CI 0.12-0.36, p=0.004; integrated discrimination improvement [IDI] 0.04, 95% CI 0.01-0.08, p=0.004) and STS score (C-statistic 0.78 vs 0.73, p=0.03; cNRI 0.16, 95% CI 0.06-0.32, p=0.002; IDI 0.02, 95% CI 0.000-0.049, p=0.048) respectively. 1 year following surgery (n=740), those with persistent concomitant inflammation and malnutrition experienced the highest risk of all-cause mortality (HR 8.82, 95% CI 4.21-18.49), cardiovascular death (SHR 12.63, 95% CI 3.85-41.39) and adverse events (HR 5.83, 95% CI 3.16-10.76) than those without (p<0.001 for all).
Conclusion
Concomitant inflammation and malnutrition is common and is strongly associated with mortality and HF in patients undergoing valvular surgery. Beyond conventional risk scores, assessments of inflammatory and nutritional status using NLR and PNI before and after surgery may provide additional prognostic value for long-term outcomes following valvular surgery.

Abstract

Type of funding sources: None.
Background
Hyperkalemia is a common complication and increases the risk of cardiac arrhythmias and mortality in patients with type 2 diabetes (T2DM), especially in those with diabetic nephropathy. We investigated the risk of hyperkalemia in patients initiated on SGLT2 inhibitors versus DPP-4 inhibitors among patients with T2DM.
Methods
This study included patients with T2DM who initiated on SGLT2 inhibitors or DPP-4 inhibitors between January 01, 2015 and December 31, 2019 from a territory-wide clinical registry in Hong Kong (Clinical Data Analysis and Reporting System [CDARS]). A multivariable cox proportional hazards analysis, adjusting for key confounders, was used to compare the risk of central laboratory-determined hyperkalemia (serum potassium ≥6.0mmol/L) and hypokalemia (serum potassium <3.5mmol/L), respectively, between SGLT2 inhibitors and DPP-4 inhibitors.
Results
10193 new users of SGLT2 inhibitors were matched to 17305 new users of DPP-4 inhibitors. During the 2-year follow-up, there were 104 hyperkalemia events (incident rate [IR] = 5.17 per 1000 person-years) among SGLT2 inhibitors and 306 events (IR = 9.09 per 1000 person-years) among DPP-4 inhibitors, of which SGLT2 inhibitors were associated with a lower risk of incident hyperkalemia (Adjusted HR: 0.66 [95%CI 0.53-0.83], p<0.001), compared to DPP-4 inhibitors. The incident hypokalemia was similar between SGLT2 inhibitors and DPP-4 inhibitors (Adjusted HR: 0.91 [95%CI 0.81-1.03], P=0.13).
Conclusion
SGLT2 inhibitors reduced incident hyperkalemia, but without increasing incident hypokalemia compared to DPP-4 inhibitors.

Abstract
Background Circulating thrombospondin-2 (TSP2) levels were associated with the development of heart failure (HF) in recent studies. However, these studies included only a minority of patients with type 2 diabetes, which is associated with an increased HF risk. As hyperglycemia induces TSP2 expression and its tissue expression increases in type 2 diabetes, we investigated the prospective association of circulating TSP2 with incident HF hospitalization (HHF), and its associations with longitudinal changes of echocardiographic parameters in type 2 diabetes. Methods Baseline serum TSP2 levels were measured in 4949 patients with type 2 diabetes to determine its association with incident HHF using multivariable Cox regression analysis. In the echocardiographic study, baseline serum TSP2 levels were measured in another 146 patients with type 2 diabetes but without cardiovascular diseases who underwent detailed transthoracic echocardiography at baseline and after 1 year. Results Over a median follow-up of 7.8 years, 330 of 4949 patients (6.7%) developed incident HHF. Baseline serum TSP2 levels were independently associated with the development of HHF (HR 1.31, 95%CI 1.06–1.62, p = 0.014) after adjustments for baseline conventional cardiovascular risk factors, atrial fibrillation, estimated glomerular filtration rate, albuminuria and high-sensitivity C-reactive protein level, use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, loop-diuretics, aspirin, insulin, metformin and sodium-glucose co-transporter 2 inhibitors. Moreover, baseline serum TSP2 levels were independently associated with increase in average E/e’ and left atrial volume index (p = 0.04 and < 0.01, respectively). Conclusion Serum TSP2 levels were independently associated with both incident HHF and deterioration in diastolic function in type 2 diabetes.

Abstract
OBJECTIVE To evaluate whether characterization of maternal and foetoplacental factors beyond birthweight can enable early identification of children at risk of developing prehypertension/hypertension. METHODS We recruited 693 mother-offspring dyads from the GUSTO prospective mother-offspring cohort. Prehypertension/hypertension at age 6 years was identified using the simplified paediatric threshold of 110/70 mmHg. We evaluated the associations of pregnancy complications (gestational diabetes, excessive/inadequate gestational weight gain, hypertensive disorders of pregnancy), foetal growth deceleration (decline in foetal abdominal circumference at least 0.67 standard deviations between second and third trimesters), high foetoplacental vascular resistance (third trimester umbilical artery systolic-to-diastolic ratio ≥90th centile), preterm birth, small-for-gestational age and neonatal kidney volumes with risk of prehypertension/hypertension at age 6 years, after adjusting for sex, ethnicity, maternal education and prepregnancy BMI. RESULTS Pregnancy complications, small-for-gestational age, preterm birth, and low neonatal kidney volume were not associated with an increased risk of prehypertension/hypertension at age 6 years. In contrast, foetal growth deceleration was associated with a 72% higher risk [risk ratio (RR) = 1.72, 95% confidence interval (CI) 1.18-2.52]. High foetoplacental vascular resistance was associated with a 58% higher risk (RR = 1.58, 95% CI 0.96-2.62). Having both these characteristics, relative to having neither, was associated with over two-fold higher risk (RR = 2.55, 95% CI 1.26-5.16). Over 85% of the foetuses with either of these characteristics were born appropriate or large for gestational age. CONCLUSION Foetal growth deceleration and high foetoplacental vascular resistance may be helpful in prioritizing high-risk children for regular blood pressure monitoring and preventive interventions, across the birthweight spectrum.

Abstract
Prenatal maternal mental health is a global health challenge with poorly defined biological mechanisms. We used maternal blood samples collected during the second trimester from a Singaporean longitudinal birth cohort study to examine the association between inter-individual genome-wide DNA methylation and prenatal maternal depressive symptoms. We found that (1) the maternal methylome was significantly associated with prenatal maternal depressive symptoms only in mothers with a female fetus; and (2) this sex-dependent association was observed in a comparable, UK-based birth cohort study. Qualitative analyses showed fetal sex-specific differences in genomic features of depression-related CpGs and genes mapped from these CpGs in mothers with female fetuses implicated in a depression-associated WNT/β-catenin signaling pathway. These same genes also showed enriched expression in brain regions linked to major depressive disorder. We also found similar female-specific associations with fetal-facing placenta methylome. Our fetal sex-specific findings provide evidence for maternal-fetal interactions as a mechanism for intergenerational transmission.

Abstract
PURPOSE There is altered breastmilk composition among mothers with gestational diabetes and conflicting evidence on whether breastfeeding is beneficial or detrimental to their offspring's cardiometabolic health. We aimed to investigate associations between breastfeeding and offspring's cardiometabolic health across the range of gestational glycemia. METHODS We included 827 naturally conceived, term singletons from a prospective mother-child cohort. We measured gestational (26-28 weeks) fasting plasma glucose (FPG) and 2-h plasma glucose (2 hPG) after an oral glucose tolerance test as continuous variables. Participants were classified into 2 breastfeeding categories (high/intermediate vs. low) according to their breastfeeding duration and exclusivity. Main outcome measures included magnetic resonance imaging (MRI)-measured abdominal fat, intramyocellular lipids (IMCL), and liver fat, quantitative magnetic resonance (QMR)-measured body fat mass, blood pressure, blood lipids, and insulin resistance at 6 years old (all continuous variables). We evaluated if gestational glycemia (FPG and 2 hPG) modified the association of breastfeeding with offspring outcomes after adjusting for confounders using a multiple linear regression model that included a 'gestational glycemia × breastfeeding' interaction term. RESULTS With increasing gestational FPG, high/intermediate (vs. low) breastfeeding was associated with lower levels of IMCL (p-interaction = 0.047), liver fat (p-interaction = 0.033), and triglycerides (p-interaction = 0.007), after adjusting for confounders. Specifically, at 2 standard deviations above the mean gestational FPG level, high/intermediate (vs. low) breastfeeding was linked to lower adjusted mean IMCL [0.39% of water signal (0.29, 0.50) vs. 0.54% of water signal (0.46, 0.62)], liver fat [0.39% by weight (0.20, 0.58) vs. 0.72% by weight (0.59, 0.85)], and triglycerides [0.62 mmol/L (0.51, 0.72) vs. 0.86 mmol/L (0.75, 0.97)]. 2 hPG did not significantly modify the association between breastfeeding and childhood cardiometabolic risk. CONCLUSION Our findings suggest breastfeeding may confer protection against adverse fat partitioning and higher triglyceride concentration among children exposed to increased glycemia in utero.

Abstract
OBJECTIVE To evaluate the effectiveness of health education on knowledge, attitude and practice (KAP) relating to malaria control among overseas enterprise employees. METHODS In September 2019, on-site malaria control health education was conducted among all Chinese employees of a China-funded mining enterprise in the Democratic Republic of Congo. The KAP questionnaire for malaria control was generated on the Questionstar website, and the participants were subjected to two questionnaire surveys prior to and 14 months after health education. After the questionnaires were recovered, all valid questionnaires were divided into 4 groups, including the baseline group (the questionnaires filled out by respondents who received health education and participated in two questionnaire surveys before health education), the loss-to-follow-up group (the questionnaires filled out by respondents who received health education but only participated in the questionnaire survey after health education), the retest group (the questionnaires filled out by respondents who received health education and participated in two questionnaire surveys after health education) and the new group (questionnaires filled out by respondents who did not receive health education and only participated in the questionnaire survey after health education) according to subjects' receiving health education and participation in two questionnaire surveys. The correct rate of malaria control knowledge, the proportion to good attitudes towards malaria control and the proportion of good practices towards malaria control were compared between the baseline group and the loss-to-follow-up group, between the baseline group and the retest group, and between the retest group and the new group. RESULTS A total of 110 and 142 valid questionnaires were recovered during the two surveys, and the recovery rates were 90.9% and 70.3%, respectively. There were 77, 77, 33, and 65 valid questionnaires recovered from the baseline group, the loss-to-follow-up group, the retest group, and the new group, respectively. There were no significant differences in respondents' gender, age and educational levels between the baseline group and the loss-to-follow-up group (all P values > 0.05), and there were no significant differences between the two groups in terms of the mean score of malaria control knowledge (Z = 2.011, P > 0.05), the mean score of attitudes towards malaria control (t = -0.787, P > 0.05) and the mean score of practices towards malaria control (t = -0.787, P > 0.05). There were significant differences between the retest group and the baseline group in terms of the mean score of malaria control knowledge (10.83 vs. 9.79; Z = -4.017, P < 0.05), the mean score of attitudes towards malaria control (29.48 vs. 28.61; Z = -1.981, P < 0.05) and the mean score of practices towards malaria control (6.43 vs. 5.91; Z = -2.499, P < 0.05). There were no significant differences between the retest group and the new group in terms of gender, age or education levels (all P values > 0.05), and a higher mean score of malaria control knowledge was found in the retest group than in the new group (10.83 vs. 9.81; Z = -2.962, P < 0.05), while no significant differences were seen in the mean score of attitudes towards malaria control (29.48 vs. 30.17; Z = -1.158, P > 0.05) and the mean score of practices towards malaria control (6.43 vs. 6.37; Z = -0.048, P > 0.05) between the two groups. CONCLUSIONS Malaria control health education may significantly improve the understanding of malaria control knowledge, positive attitudes towards malaria control and the compliance of practices towards malaria control among overseas enterprise employees.

Abstract
Objective: To screen and perform preliminary clinical validation of biomarkers of activity based on positron emission tomography/computed tomography (PET-CT) and transcriptomics in sputum-negative pulmonary tuberculosis lesion tissue. Methods: Nine patients with sputum-negative pulmonary tuberculosis treated surgically at the Shanghai Public Health Clinical Center for Thoracic Surgery from January 1, 2017 to December 31, 2019 were retrospectively collected as the discovery group, including four males and five females, aged 20-57 years (mean 36 years). All of the patients underwent PET-CT scanning before surgery, and the resected specimens were postoperatively classified according to preoperative PET-CT. The resected specimens were divided into areas with increased fluorodeoxyglucose (FDG) metabolism (SUVmax>3) and areas with normal FDG metabolism (SUVmax ≤ 3) according to the preoperative PET-CT performance. After sample processing, total RNA was extracted from the tissues of different regions, and then whole gene transcriptome sequencing was performed. Bioinformatics analysis of the two sets of data was performed to discover the expression profiles of the differences in whole gene transcriptome data between the two regions and to screen for candidate biomarkers. Eighty patients with sputum-negative pulmonary tuberculosis admitted to Shanghai Public Health Clinical Center from January 1, 2019 to January 1, 2021 were retrospectively collected as the validation group, including 37 males and 43 females, aged 20-62 years, with an average age of 39 years. The validation group was divided into a group with increased SUV (n=40) and a group without lesions on CT imaging (n=40). Enzyme-linked immunosorbent assay (ELISA) was used to determine the protein levels of candidate biomarkers in the peripheral plasma of patients. The effect of biomarkers was assessed using subject operating characteristic (ROC) curves. Student's t-test was used to determine whether the difference in protein levels between the two groups was statistically significant. Results: Bioinformatics analysis revealed that the expression levels of C1QB, CCL19, CCL5 and HLA-DMB correlated with the metabolic activity of sputum-negative tuberculosis lesion tissue. Further screening and validation by the validation group confirmed that the difference in C1QB protein levels in the peripheral plasma of patients was statistically significant between the group with increased SUV and the group without lesions on CT imaging [(3.55±0.34) mg/L vs. (2.75±0.21) mg/L, t=4.12, P<0.001]. And the ROC curve showed that the area under the curve for C1QB protein levels was 0.731, which had potential clinical value. Conclusion: The C1QB protein level can be used to assess the activity of lesions in patients with sputum-negative tuberculosis and is a potential biomarker.

Abstract
BACKGROUND Maternal obesity increases the risk of adverse long-term health outcomes in mother and child including childhood obesity. We aimed to investigate the association between interpregnancy weight gain between first and second pregnancies and risk of overweight and obesity in the second child. METHODS We analysed the healthcare records of 4789 women in Hampshire, UK with their first two singleton live births within a population-based anonymised linked cohort of routine antenatal records (August 2004 and August 2014) with birth/early life data for their children. Measured maternal weight and reported height were recorded at the first antenatal appointment of each pregnancy. Measured child height and weight at 4-5 years were converted to age- and sex-adjusted body mass index (BMI z-score). Log-binomial regression was used to examine the association between maternal interpregnancy weight gain and risk of childhood overweight and obesity in the second child. This was analysed first in the whole sample and then stratified by baseline maternal BMI category. RESULTS The prevalence of overweight/obesity in the second child was 19.1% in women who remained weight stable, compared with 28.3% in women with ≥3 kg/m2 weight gain. Interpregnancy gain of ≥3 kg/m2 was associated with increased risk of childhood overweight/obesity (adjusted relative risk (95% CI) 1.17 (1.02-1.34)), with attenuation on adjusting for birthweight of the second child (1.08 (0.94-1.24)). In women within the normal weight range at first pregnancy, the risks of childhood obesity (≥95th centile) were increased with gains of 1-3 kg/m2 (1.74 (1.07-2.83)) and ≥3 kg/m2 (1.87 (1.18-3.01)). CONCLUSION Children of mothers within the normal weight range in their first pregnancy who started their second pregnancy with a considerably higher weight were more likely to have obesity at 4-5 years. Supporting return to pre-pregnancy weight and limiting weight gain between pregnancies may achieve better long-term maternal and offspring outcomes.

Abstract
Objective: To analyze the pathogenic bacteria and epidemiological characteristics in children with respiratory tract infection in Tianjin area. Methods: Retrospective case analysis was performed on 2 392 hospitalized children in the wards of respiratory diseases, intensive care unit and special care ward of Tianjin Children's Hospital from June 2018 to May 2019. Thirteen pathogenic bacteria in deep sputum and bronchoalveolar lavage fluid samples were detected by loop-mediated isothermal amplification. The laboratory data and clinical characteristics of the infected children were analyzed, and the comparison between groups was performed by t test or χ2 test. Results: Among 2 392 cases, 1 407 were males and 985 females. There was no significant difference in the detection rate between males and females (72.5% (1 020/1 407) vs.74.2% (731/985), χ2=0.87, P=0.35). A total of 1 751 strains and 12 kinds of positive respiratory pathogens were detected, with a detection rate of 73.2%. Among them, 913 (38.2%) strains were Mycoplasma pneumoniae (MP), 514 (21.5%) were Streptococcus pneumoniae (Sp), 381 (15.9%) were Methicillin-resistant Staphylococcus aureus (MRSA) and 279 (11.7%) were Hemophilus influenzae (Hi). There was significant difference in the detection rate of pathogens among different age groups (χ²=83.67, P<0.01). The positive rate of alveolar lavage fluid group was higher than that of deep sputum fluid group [81.6% (614/752) vs. 69.3% (1 137/1 640), χ2=39.89, P<0.01]. The length of hospital stay of children infected with different pathogens was significantly different (all P<0.01). There was significant difference in duration of fever among children infected with different pathogens (χ²=228.69,103.56, 3.96, 27.38,24.50,41.66, all P<0.05). There were 63 (7.7%) cases of atelectasis, 260 (31.9%) cases of pleurisy and 120 (14.7%) cases of pleural effusion in MP children. Children with Sma were most likely to involve the heart system (2/9), and children with Eco infection had a higher incidence of complications such as those of blood (3/19), urinary (2/19), digestive systems(4/19), systemic inflammatory response syndrome and sepsis (1/19). Conclusions: The main bacterial pathogens of respiratory tract infection in children in Tianjin were MP, Sp, MRSA and Hi. It is suggested that clinicians should not only pay attention to the respiratory symptoms of children, but also pay attention to the complications caused by bacterial pathogen infection, so as to prevent the deterioration of the disease and improve the prognosis.

Abstract
Objective: To compare the expression and difference of melastatin-related transient receptor potential 8(TRPM8) among chronic rhinosinusitis, nasal polyps and normal mucosa tissues. And to explore the significant expression of TRPM8 among CRSwNP. Methods: Fifty-one patients underwent endoscopic sinus surgery in the Department of Otorhinolaryngology Head and Neck Surgery of Renmin Hospital of Wuhan University from February 2019 to January 2020 were recruited, including 33 males and 18 females, aged from 14 to 65 years old (34.55±1.689).Immunohistochemistry was used to detected the expression of TRPM8 protein among CRSsNP(17),CRSwNP (17) and control tissuses(17). In addition, the correlation between the expression of TRPM8 protein in CRSwNP patients and preoperative CT Lund-Mackay scores and preoperative VAS scores and sinonasal outcome test-20 scores was analyzed, respectively. The primary human nasal epithelial cells were cultured in vitro and the expression of TRPM8 was detected by quantitative real-time PCR and western blotting. The tissue in control group, chronic rhinosinusitis without nasal polyps (CRSsNP) group and the CRSwNP group were collected and grinded into tissue homogenized. The expression of TRPM8 protein was detected by western blotting after 24 h stimulation after homogenate was added into the medium of RPMI 2650 and primary nasal epithelial cells. Results: Compared with the control, the expression of TRPM8 was significantly up-regulated in nasal polyps (t=6.852, P<0.05). TRPM8 was mainly expressed in epithelial cells. The expression of TRPM8 in the epithelial cells of CRSsNP had no difference with the control group (t=1.980, P>0.05). In addition, the expression of TRPM8 in CRSwNP patients was positively correlated with the preoperative CT Lund-Mackay scores and VAS scores and SNOT-20 scores (r=0.512, P<0.05;r=0.853, P<0.01;r=0.814, P<0.01). After cultured primary epithelial cells in vitro, the expression level of TRPM8 in epithelial cells derived from nasal polyp was significantly higher than that in control group (t=8.845, P<0.05). By adding the homogenization of control and CRSsNP and CRSwNP tissues, the expression of TRPM8 in RPMI 2650 cells and primary nasal epithelial cells was changed and that was significantly increased after adding the homogenization of the group of CRSwNP. Conclusion: TRPM8 is highly expressed in nasal polyps epithelial cells, suggesting that TRPM8 may be involved in the pathogenesis of nasal polyps regulated by nasal epithelial cells.

Abstract
Objective: To study the relationship between emotional apathy and motor symptoms, sleep, and cognitive function in patients with early Parkinson's disease (PD). Methods: One hundred and twenty-nine early PD patients who were treated in the Second Affiliated Hospital of Soochow University from June to October 2020 were included, including 82 male and 47 female patients. The emotional apathy was assessed by modified apathy rating scale (MAES). The above 129 patients were divided into 67 patients in the PD with emotional apathy group (MAES>14 points) and 62 patients in the PD without emotional apathy group (MAES≤ 14 points). Age, gender, course of disease and levodopa equivalent dose were also collected. Hoehn-Yahr stage and unified Parkinson's disease rating scale PartⅢ(UPDRS-Ⅲ), Pittsburgh Sleep Quality Index (PSQI), polysomnography, and Montreal Cognitive Assessment Scale (MoCA) were used to evaluate the motor symptoms, sleep and cognitive functions of patients with early PD, and the clinical characteristics of patients with early PD with apathywere determined. Results: Compared with PD patients without apathy, those with apathy had longer disease duration [M(Q1,Q3)][5.0 (3.0, 7.0) years vs 3.0 (2.0, 5.0) years, P=0.006] and severer motor symptoms [20.0 (10.0, 28.0) vs 14.0 (8.5, 23.0), P=0.047]. There was no significant difference in PSQI score between the two groups. Among the 33 patients who completed polysomnography, compared with PD patients without apathy (n=16), those with apathy (n=17) had a longer rapid eye movement (REM) sleep latency [150 (124, 184) min vs 87 (57, 133) min, P=0.035)] and more frequent periodic limb movements in the REM phase(P=0.042).The REM sleep ratio (r=0.373, P=0.042), apnea-hypopena index (AHI)(r=0.374, P=0.046) and oxygen deficit index (r=0.409, P=0.025) were positively correlated with the degree of apathy in PD patients. PD patients with apathy had relatively poorer performance in cognition assessment than those without apathy and total MoCA score was inversely correlated with the degree of apathy (r=-0.231, P=0.017). Conclusion: Early PD patients with apathy have objective sleep disorders dominated by REM sleep disorders, which can have a negative impact on cognitive function.

Abstract
BACKGROUND Randomised controlled trials in reproductive medicine are often subject to outcome truncation, where the study outcomes are only defined in a subset of the randomised cohort. Examples include birthweight (measurable only in the subgroup of participants who give birth) and miscarriage (which can only occur in participants who become pregnant). These outcomes are typically analysed by making a comparison between treatment arms within the subgroup (for example, comparing birthweights in the subgroup who gave birth or miscarriages in the subgroup who became pregnant). However, this approach does not represent a randomised comparison when treatment influences the probability of being observed (i.e. survival). The practical implications of this for the design and interpretation of reproductive trials are unclear however. METHODS We developed a simulation platform to investigate the implications of outcome truncation for reproductive medicine trials. We used this to perform a simulation study, in which we considered the bias, type 1 error, coverage, and precision of standard statistical analyses for truncated continuous and binary outcomes. Simulation settings were informed by published assisted reproduction trials. RESULTS Increasing treatment effect on the intermediate variable, strength of confounding between the intermediate and outcome variables, and the presence of an interaction between treatment and confounder were found to adversely affect performance. However, within parameter ranges we would consider to be more realistic, the adverse effects were generally not drastic. For binary outcomes, the study highlighted that outcome truncation could cause separation in smaller studies, where none or all of the participants in a study arm experience the outcome event. This was found to have severe consequences for inferences. CONCLUSION We have provided a simulation platform that can be used by researchers in the design and interpretation of reproductive medicine trials subject to outcome truncation and have used this to conduct a simulation study. The study highlights several key factors which trialists in the field should consider carefully to protect against erroneous inferences. Standard analyses of truncated binary outcomes in small studies may be highly biassed, and it remains to identify suitable approaches for analysing data in this context.

Abstract
STUDY QUESTION What is the transcriptome signature associated with poor performance of rescue IVM (rIVM) oocytes and how can we rejuvenate them? SUMMARY ANSWER The GATA-1/CREB1/WNT signalling axis was repressed in rIVM oocytes, particularly those of poor quality; restoration of this axis may produce more usable rIVM oocytes. WHAT IS KNOWN ALREADY rIVM aims to produce mature oocytes (MII) for IVF through IVM of immature oocytes collected from stimulated ovaries. It is not popular due to limited success rate in infertility treatment. Genetic aberrations, cellular stress and the absence of cumulus cell support in oocytes could account for the failure of rIVM. STUDY DESIGN, SIZE, DURATION We applied single-cell RNA sequencing (scRNA-seq) to capture the transcriptomes of human in vivo oocytes (IVO) (n = 10) from 7 donors and rIVM oocytes (n = 10) from 10 donors. The effects of maternal age and ovarian responses on rIVM oocyte transcriptomes were also studied. In parallel, we studied the effect of gallic acid on the maturation rate of mouse oocytes cultured in IVM medium with (n = 84) and without (n = 85) gallic acid. PARTICIPANTS/MATERIALS, SETTING, METHODS Human oocytes were collected from donors aged 28-41 years with a body mass index of <30. RNA extraction, cDNA generation, library construction and sequencing were performed in one preparation. scRNA-seq data were then processed and analysed. Selected genes in the rIVM versus IVO comparison were validated by quantitative real-time PCR. For the gallic acid study, we collected immature oocytes from 5-month-old mice and studied the effect of 10-μM gallic acid on their maturation rate. MAIN RESULTS AND THE ROLE OF CHANCE The transcriptome profiles of rIVM/IVO oocytes showed distinctive differences. A total of 1559 differentially expressed genes (DEGs, genes with at least 2-fold change and adjusted P < 0.05) were found to be enriched in metabolic processes, biosynthesis and oxidative phosphorylation. Among these DEGs, we identified a repression of WNT/β-catenin signalling in rIVM when compared with IVO oocytes. We found that oestradiol levels exhibited a significant age-independent correlation with the IVO mature oocyte ratio (MII ratio) for each donor. rIVM oocytes from women with a high MII ratio were found to have over-represented cellular processes such as anti-apoptosis. To further identify targets that contribute to the poor clinical outcomes of rIVM, we compared oocytes collected from young donors with a high MII ratio with oocytes from donors of advanced maternal age and lower MII ratio, and revealed that CREB1 is an important regulator. Thus, our study identified that GATA-1/CREB1/WNT signalling was repressed in both rIVM oocytes versus IVO oocytes and in rIVM oocytes of lower versus higher quality. Consequently we investigated gallic acid, as a potential antioxidant substrate in human rIVM medium, and found that it increased the mouse oocyte maturation rate by 31.1%. LARGE SCALE DATA Raw data from this study can be accessed through GSE158539. LIMITATIONS, REASONS FOR CAUTION In the rIVM oocytes of the high- and low-quality comparison, the number of samples was limited after data filtering with stringent selection criteria. For the oocyte stage identification, we were unable to predict the presence of oocyte spindle, so polar body extrusion was the only indicator. WIDER IMPLICATIONS OF THE FINDINGS This study showed that GATA-1/CREB1/WNT signalling was repressed in rIVM oocytes compared with IVO oocytes and was further downregulated in low-quality rIVM oocytes, providing us the foundation of subsequent follow-up research on human oocytes and raising safety concerns about the clinical use of rescued oocytes.

Abstract
CONTEXT Cardiometabolic profiles of different body composition phenotypes are poorly characterized in young children, where it is well established that high adiposity is unfavorable, but the role of lean mass is unclear. OBJECTIVE We hypothesized that higher lean mass attenuates cardiometabolic risk in children with high fat mass. METHODS In 6-year-old children (n = 377) from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) prospective birth cohort, whole-body composition was measured by quantitative magnetic resonance, a novel validated technology. Based on fat mass index (FMI) and lean mass index (LMI), 4 body composition phenotypes were derived: low FMI-low LMI (LF-LL), low FMI-high LMI (LF-HL), high FMI-low LMI (HF-LL), high FMI-high LMI (HF-HL). MAIN OUTCOME MEASURES Body mass index (BMI) z-score, fasting plasma glucose, insulin resistance, metabolic syndrome risk score, fatty liver index, and blood pressure. RESULTS Compared with the LF-HL group, children in both high FMI groups had increased BMI z-score (HF-HL: 1.43 units 95% CI [1.11,1.76]; HF-LL: 0.61 units [0.25,0.96]) and metabolic syndrome risk score (HF-HL: 1.64 [0.77,2.50]; HF-LL: 1.28 [0.34,2.21]). The HF-HL group also had increased fatty liver index (1.15 [0.54,1.77]). Girls in HF-HL group had lower fasting plasma glucose (-0.29 mmol/L [-0.55,-0.04]) and diastolic blood pressure (-3.22 mmHg [-6.03,-0.41]) than girls in the HF-LL group. No similar associations were observed in boys. CONCLUSION In a multi-ethnic Asian cohort, lean mass seemed to protect against some cardiometabolic risk markers linked with adiposity, but only in girls. The FMI seemed more important than lean mass index in relation to cardiometabolic profiles of young children.

Abstract
BACKGROUND Using longitudinal ultrasounds as an improved fetal growth marker, we aimed to investigate if fetal growth deceleration followed by rapid postnatal weight gain is associated with childhood cardiometabolic risk biomarkers in a contemporary well-nourished population. METHODS We defined fetal growth deceleration (FGD) as ultrasound-measured 2nd-3rd-trimester abdominal circumference decrease by ≥0.67 standard deviation score (SDS) and rapid postnatal weight gain (RPWG) as 0-2-year-old weight increase by ≥0.67 SDS. In the GUSTO mother-offspring cohort, we grouped 797 children into four groups of FGD-only (14.2%), RPWG-only (23.3%), both (mismatch, 10.7%) or neither (reference, 51.8%). Adjusting for confounders and comparing with the reference group, we tested associations of these growth groups with childhood cardiometabolic biomarkers: magnetic resonance imaging (MRI)-measured abdominal fat (n = 262), liver fat (n = 216), intramyocellular lipids (n = 227), quantitative magnetic resonance-measured overall body fat % (BF%) (n = 310), homeostasis model assessment of insulin resistance (HOMA-IR) (n = 323), arterial wall thickness (n = 422) and stiffness (n = 443), and blood pressure trajectories (ages 3-6 years). RESULTS Mean±SD birthweights were: FGD-only (3.11 ± 0.38 kg), RPWG-only (3.03 ± 0.37 kg), mismatch (2.87 ± 0.31 kg), reference (3.30 ± 0.36 kg). FGD-only children had elevated blood pressure trajectories without correspondingly increased BF%. RPWG-only children had altered body fat partitioning, higher BF% [BF = 4.26%, 95% confidence interval (CI) (2.34, 6.19)], HOMA-IR 0.28 units (0.11, 0.45)] and elevated blood pressure trajectories. Mismatch children did not have increased adiposity, but had elevated ectopic fat, elevated HOMA-IR [0.29 units (0.04,0.55)] and the highest blood pressure trajectories. Associations remained even after excluding small-for-gestational-age infants from analyses. CONCLUSIONS Fetal growth deceleration coupled with rapid postnatal weight gain was associated with elevated childhood cardiometabolic risk biomarkers without correspondingly increased BF%.

Abstract
Objective: To investigate the significance of plasma pentraxin 3 (PTX3) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH). Methods: Plasma PTX3 levels were tested by ELISA in 48 newly diagnosed sHLH patients, 18 healthy volunteers and 9 lymphoma controls in the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2019. Clinical parameters were collected, and the correlations with PTX3 levels were analyzed. Results: PTX3 level in newly diagnosed group was significantly higher than that of healthy control group [16.29(1.17-66.00) vs. 0.76(0.01-7.86) μg/L, P<0.01]. Patients with lymphoma-associated HLH(LHLH) had higher plasma level of PTX3 than Fhose with infection-associated HLH (IHLH) [24.29(3.36-66.00) vs. 9.56(1.17-36.50)μg/L, P<0.05]. Plasma PTX3 levels in 48 sHLH patients were positively correlated with serum ferritin (P<0.05). Receiver operating characteristic (ROC) curve for plasma PTX3 levels of sHLH and healthy controls produced a cutoff value at 3.9 μg/L, with its 86.7% sensitivity and 94.4% specificity. And ROC analysis showed that PTX3 17.5 μg/L was the critical value for diagnosis of LHLH from non-LHLH group, that the sensitivity and specificity were 63.0% and 76.2% respectively. The 1-year overall survival (OS) rate in patients with PTX3≥17.5 μg/L was significantly lower in those with PTX3<17.5 μg/L (18.5% vs. 75.8%, P<0.01). Conclusion: These results indicate the potential of PTX3 as a biomarker for diagnosis and prognosis in patients with sHLH.

Abstract
On March 11, 2020, WHO officially declared that COVID-19 had become Pandemic. As of March 31, the epidemic had affected more than 178 countries and regions, with more than 780 000 confirmed cases. The Pandemic Influenza Preparedness Framework for the sharing of influenza viruses and access to vaccines and other benefits (the 'PIP Framework' or 'Framework') is an international arrangement adopted by the World Health Organization in May 2011 to improve global pandemic influenza preparedness and response. Since the transmission route and transmission capacity of COVID-19 are similar to that of influenza A (H1N1) in 2009, which conforms to the basic elements of "human pandemic", and the epidemic scale has exceeded that of influenza A (H1N1), it is probable to incorporate COVID-19 epidemic response into PIPF, and at the same time to verify and improve PIPF in practice. It is recommended that WHO, other international organizations and relevant countries make full use of the PIPF system to respond to the epidemic and better coordinate national actions at the global level. At the same time, China should also make the planning and deploy of domestic epidemic prevention and control and international epidemic cooperation under the framework.

Abstract
Objective: To investigate the feasibility of echocardiography-guided closed-chest repeated intraventricular blood sampling in mice, and to clarify the maximum blood volume that can be collected by this method, and whether the method can be used for long-term repeated blood collection in mice. Methods: Twenty-four male C57BL/6J mice (10-14 weeks old) were divided into the terminal experiment group (n=4, for investigating the maximum blood amount that could be sampled at one time), the repeated 0.5 ml blood collection group (n=10, sampling 0.5 ml whole blood each time, once every two days for consecutive 4 weeks), and the repeated 0.75 ml blood collection group (n=10, sampling 0.75 ml whole blood each time, once every two days for consecutive 4 weeks). High-frequency echocardiography was used to display the largest section of the left ventricle, guiding the insulin syringe needle through the thorax into the left ventricle for blood collection. In the repeated 0.5 ml blood collection group, echocardiography was used to detect the cardiac structure and function before blood collection, three minutes after blood collection, and one week after the last (the 14th) blood collection. Results: We successfully performed echocardiography-guided closed-chest intraventricular blood sampling, with an average operating time (88±19)s per mouse, and a maximum blood volume (1.43±0.11)ml per mouse. In the repeated 0.5 ml blood collection group, heart rate, left ventricular ejection fraction, left ventricular fractional shortening, left ventricular end-diastolic dimension and left ventricular posterior wall end-diastolic thickness remained uncganged before the first blood collection and after 4 weeks of repeated blood collection (all P>0.05). No death in the repeated 0.5 ml blood collection group. However, in the 0.75 ml blood collection group, two mice died before the end point. Conclusions: The echocardiography-guided closed-chest intraventricular blood sampling is a safe, minimally invasive, convenient and efficient method, and can be used repeatedly for long-term blood collection in mice.

Abstract
Objective: To explore the association of the glycosylated hemoglobin (HbA1c) level at admission with 90 days functional outcome in patients with spontaneous intracerebral hemorrhage (ICH). Methods: Patients admitted to the Department of Neurology, Tongji Hospital from January to December 2017 were prospectively and continuously enrolled in this study. Clinical data were collected at admission and functional outcomes 90 days after ICH were assessed by using the modified RANKIN scale. Univariate and multivariate conditional logistic regression models were constructed. Patients were divided into four groups according to the quartile of HbA1c values. The median value of HbA1c in each group was taken as the substitute value and P for trend was calculated. The logistic regression model was fitted by restricted cubic splines to investigate the association between HbA1c level and outcome of ICH. Results: A total of 345 patients with ICH were enrolled, including 214 with favorable outcomes and 131 with poor outcomes (99 severe disability cases and 32 deaths). The risk of poor 90 days outcomes was significantly associated with HbA1c level at admission indicated by multivariate logistic regression analysis, and the P for trend test was <0.001 (middle-level group vs. low-level group: OR=2.33, 95%CI: 1.07-5.07; high-level group vs. low-level group: OR=2.52, 95%CI: 1.12-5.64; extremely high-level group vs. low-level group: OR=6.80, 95%CI: 3.01-15.34). Results from the restricted cubic spline showed that there was a linear correlation between HbA1c level at admission and poor 90 days outcomes of ICH (χ(2)=14.81, P<0.001; non- linear test: P=0.118). Compared with patients with HbA1c level of 6.5%, the risk of poor outcomes in patients with HbA1c level of <6.5% decreased linearly with the decrease in HbA1c level at admission, and the risk in patients with HbA1c level >6.5% was higher but not significantly. Conclusion: There was correlation between high HbA1c level at admission and 90 days poor outcome of ICH. High HbA1c level is an independent prediction indicator for ICH.

Abstract
Objective:This study was designed to show the preliminary efficacy and safety of the improved tongue base suspension surgery in severe obstructive sleep apnea(OSA) patients classified as Friedman Ⅱand Friedman Ⅲ. Method:The severe OSA patients diagnosed by PSG as Friedman Ⅱ type and Ⅲ type underwent surgery treatment. The tongue base of the patient was implanted with titanium plate and fixed on the chin of mandible. The UPPP surgery was performed with reference to H-UPPP. After surgery, the patients were followed up, PSG was re-examined and the change of various subjective and objective indicators of rehabilitation and adverse reactions were observed and recorded.Result: One hundred and two patients with severe OSA who were not tolerant or unwilling to use CPAP treatment were treated by the above surgical method. All the patients underwent surgery successfully and generally recovered about 1 month after the surgery without obvious tongue base pain, foreign body sensation or other discomfort. Eating and speaking function were as usual, the wound was healed well, and no serious infection or rejection was observed. The main postoperative adverse reactionwas tension line fracture(3 cases). Sixty-seven patients completed follow-up. At 3 to 6 months after surgery, the AHI, ESS sleepiness score and snore index were lower than those before surgery, while LSaO₂and CT 90% were higher than those before surgery(P<0.01). The AHI before surgery was 60.5± 22.4, and the average AHI after surgery was 27.8± 22.4. The effective rate of the surgery was 71.6% and the success rate was 58.2%. The AHI has dropped by an average of 54.0%, and snore improved by 63.9%. Conclusion: After preliminary clinical observation, the study suggests that the improved tongue base suspension with UPPP has satisfactory curative effect and feasibility for the treatment of severe OSA patients classified as Friedman Ⅱ type and Ⅲ type.

Abstract
Objective: To investigate and predict the behavioral intention and mode of the protective equipment utilization selection of the workers who used Benzene, the Theory of Planned Behavior (TPB) was applied to establish the behavioral model to enhance the theoretical foundation for long-term intervention. Methods: Questionnaires were used to survey the 707 workers, and all the behaviors of using protective equipment were investigated. Evaluate the relationships between each variable and obtain the influence affects by structural equation model. Results: The investigation showed that 38.47% of the total workers (272 cases) used whole body protection, 13.58% used partially, and 16.69% didn't use any body protection. There were significant difference between the varying degrees in the four dimensions (behavioral attitude, perceived behavior control, subjective norm, and behavioral intention) (P<0.01) . The results of structural equation model revealed that perceived behavior control was the most important influencing factor, subjective norm, positive attitude, negative attitude were the other three respects in sequence. The path co-efficient were 0.600、0.215、0.141 and 0.046 respectively. Conclusion: The study show that the theory of planned behavior can effectively explain the behavioral intention and behavior of protective equipment utilization. Therefore, combining the subjective initiative of individuals with the supervision of enterprises, In order to effectively enhance the protective equipment utilization of benzene workers.

Abstract
SummaryMouse monoclonal antibodies were derived against a plasminogen activator inhibitor with a mol.wt. of ∼54,000 (54 K) from the human fibrosarcoma cell line HT-1080. Screening for hybrids producing antibodies directed against the inhibitor was performed with enzyme-linked immunosorbent assay and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) followed by immunoblotting. Four clones of hybridomas producing IgG1 antibodies were further characterized. The inhibitor was purified ∼50-fold to homogeneity from conditioned cell culture fluid with a yield of ∼85% by a one-step procedure using Sepharose-conjugated monoclonal antibody. In the 125I-fibrin plate assay one of the antibodies neutralized the effect of the inhibitor on urokinase-type plasminogen activator. Two of the antibodies bound complexes between urokinase-type plasminogen activator and inhibitor while the remaining two antibodies did not. The antibodies could be used for immunocytochemical localization of the inhibitor in HT-1080 cells. All four antibodies cross-reacted with a plasminogen activator inhibitor derived from cultured human umbilical cord endothelial cells.

Abstract
Objective: To investigate the current status of malaria rapid diagnostic test (RDT) strips application and malaria laboratory technicians' evaluation about them at primary healthcare provider level in Jiangsu Province. Methods: From November to December 2016, 878 medical institutions and 118 CDCs of city, county and township/community level in Jiangsu Province were selected as study samples using stratified random sampling method. Self-designed questionnaire was distributed to investigate the institution's malaria work task, RDT strips application and evaluation status in 2015. We also investigated the socio-demographic information and collected the RDT strips evaluation score from the malaria laboratory technicians selected from the institutions investigated (one technician from each institution). Rank sum test was performed to compare the RDT strips evaluation scores between medical institutions and CDCs, and among different medical institutions and CDCs. Results: In 2015, 405 cases of malaria were reported, 362 200 person-time of malaria blood testing task was conducted, and 100 000 RDT strips were procured and provided for healthcare providers in Jiangsu province for free. Of the 996 healthcare institutions investigated, 628 used RDT strips in the year 2015 and the median (P(25), P(75)) of RDT strips volume used in these institutions was 10 (2, 25). The volume of RDT strips used in CDCs (15 (5, 52)) was significantly higher than that in medical institutions (10 (2, 25), (Z=3.42, P=0.001)). The investigated CDCs gave higher score on RDT strips' testing time per operation (10 (8.5, 10)) than medical institutions (9(8, 10), (Z=-2.20, P=0.028)). The employers of 614 investigated malaria laboratory technicians used RDT strips in 2015. The median of the scores given by CDC malaria laboratory technicians for RDT strips in terms of testing time per operation, testing operation and results judgement difficulties were 10 (9, 10), 10 (9, 10) and 10 (9, 10), respectively, which were significantly higher than those from technicians of medical institutions (9 (8, 10), 9 (8, 10), 9 (8, 10), (Z values were -2.55, -2.97 and -2.96, respectively; P values were all less than 0.05)). Conclusion: RDT strips had been widely performed in health institutions in Jiangsu Province. The amount of RDT strips used in CDCs was significantly higher than that in medical institutions. Primary-level institutions and malaria laboratory technicians generally recognized RDT strips' advantage for application in terms of testing time and operational procedure. CDCs and malaria laboratory technicians from them gave higher regards on RDT strips in terms of testing time per operation, testing operation and results judgement difficulties compared with that of medical institutions.

Abstract
Studies investigating the associations between exposure of young men to polybrominated diphenyl ethers (PBDEs) or phthalates and hormone levels or semen quality have produced inconsistent results. Our goal was to investigate the association of exposure to PBDEs or phthalate metabolites with changes in markers of thyroid (TSH, free T3 and free T4) and reproductive function (sperm concentrations, motility, and quality; serum LH and testosterone) in 153 healthy young men from the greater Montreal area. Using covariate-adjusted models, we found that each 10-fold increase in BDE-47 was associated with lower TSH levels (-17.3%; 95% CI: -31.5, 0.0; p = 0.05). BDE-47 exposure was also associated with a decrease in sperm concentration (-19.7%; 95% CI: -36.8; 2.0; p = 0.07) and motility (-25.5%; 95% CI: -44.5, 0.1; p = 0.05). Trends towards decreases in these parameters were also observed in association with exposure to BDE-100 and the sum of BDE-47, -99, and -100 (∑3BDEs). These associations were not accompanied by effects on sperm chromatin quality, as assessed with the HT-COMET assay. There were no substantial associations between urinary phthalate metabolite concentrations, either individually or grouped by molecular weight or parent compound, and sperm quality parameters; however, there was a positive association between elevated MECCP and free T4 (0.98; 95% CI: 0.02, 1.94; p = 0.05). Inverse associations between BDE-47 and ∑3BDEs and free T3 and positive associations between MEHP and free T3 were stronger among individuals with BMI ≥ 25, suggesting that weight status may modify the effects of these endocrine disrupting chemicals.

Abstract
Objective: By evaluating the hemodynamic parameters such as cardiac output (CO), right ventricular pressure (RVP), pulmonary artery pressure (PAP) and total pulmonary resistance index (TPRI) in pulmonary hypertension rat model, we established a more comprehensive hemodynamic evaluation system, which objectively evaluated the severity of disease and exercise tolerance in rats with pulmonary hypertension. Methods: SD rats were randomly divided into a control group and a model group with 5 rats in each group. The model group was intraperitoneally injected with SU5416 (20 mg/kg) and placed in an oxygen chamber at a 10% oxygen concentration for 21 days and then placed in a normoxic environment for 14 days. After modeling, rats were anesthetized and mechanically ventilated. The operator cut the skin along the right paraxial line, detached and ligated the intercostal artery, and then cut off the 3 and 4 ribs, exposing the heart and freeing aortic root about 0.2 cm. The flowmeter probe was set in the dissected aortic segment, and real-time recording time, blood flow waveforms, cardiac output were calculated accordingly. Then the needle attached to the baroreceptor was inserted into the right ventricle and the system acquired the right ventricular time-pressure waveform. After the waveform stabilized for about 30 seconds, the end of the cannula was sent to the pulmonary artery trunk through the entrance of the pulmonary artery to record the time-pressure curve of the pulmonary artery. Results: RVSP, PASP, PADP and mPAP in the model group were significantly higher than those of the control group [ RVSP(23.4±5.4) mmHg, 1 mmHg=0.133 kPa vs (56.4±13.0) mmHg, PASP (22.8±4.4) mmHg vs (58.5±14.9) mmHg, PADP (9.7±1.9) mmHg vs (30.3±7.0) mmHg, mPAP (14.1±2.7) mmHg vs (41.9±8.0) mmHg, all P<0.05 ]. Compared with the control group, the cardiac index in the model group was significantly lower [ CI (0.54±0.08) ml·min(-1)·g(-1) vs (0.40±0.09) ml·min(-1)·g(-1,) P=0.02 ]. Furthermore, compared with the control group, pulmonary vascular resistance index was significantly increased in the model group[PVRI (0.27±0.03) mmHg·ml(-1)·min(-1)·kg(-1) vs (0.06±0.01) mmHg·ml(-1)·min(-1)·kg(-1,) P<0.05]. The pathological results also showed that the middle part of pulmonary arterioles in the model group had muscular hypertrophy and muscular pulmonary arterioles, and even plexiform lesions. Conclusion: In this study, we established a new method that simultaneously determined several hemodynamic parameters such as RVSP, PASP, PADP, CO, CI and PVRI, which provided a more comprehensive assessment of hemodynamic changes in pulmonary hypertension rat models.

Abstract
Objective:To investigate the clinical features and reasonable surgical treatment of facial basal cell carcinoma (BCC). Method:The clinical features of primary facial BCC from 37 patients were analyzed.All patients were cured by standard surgical excision with intraoperative frozen section examination and ensuring margins negative,the defects were reconstructed by using adaptive flaps after resection. Result:The patients were followed up for 12 to 36 months after operation.Two cases of 37(2/37,5.41%) with unclear margin developed local recurrence during 4-6 months after resection,the cure rate was 94.59% (35/37). Except 4 cases were suffered with distal skin flap necrosis, the others were well developed. Conclusion:The clinical feature of primary facial basal cell carcinoma was various. The complete resection of primary nidus with clear margin is the key to a successful treatment of facial basal cell carcinoma, and satisfactory therapeutic effects can be obtained after repairing defects by using adaptive flaps after resection.

Abstract
To study the curative effects and safety for patients who adopt both gefitinib and platinum-based chemotherapy or only platinum-based chemotherapy in the treatment of lung adenocarcinoma, 80 EGFR mutation-positive lung adenocarcinoma patients in stage IIIB/IV were divided into two groups. Half of them received both gefitinib and standard chemotherapy (group A), and the others (group B) received only standard chemotherapy. Overall response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and the related toxicities of both groups were recorded in order to take certain nursing measures for a variety of toxicities. Next, statistical methods were used to analyze the curative effects and safety of the two treatments. The results showed that ORR, DCR and median progression-free (mPFS) survival of the two groups of patients showed no statistical difference (P >0.05). However, group A (18.56 months) had a longer median overall survival (mOS) than group B (14.87 months), which was of statistical significance (P less than 0.05). Nausea and loss of appetite were common mild adverse reactions, and anemia and leukocytopenia were moderate common adverse reactions. The difference between these two groups of patients regarding adverse reactions was not statistically significant (P>0.05). In conclusion, the two treatments have similar safety, but lung adenocarcinoma patients with drug resistance during stage IIIB/IV after using first-line gefitinib therapy have lower survival benefits than patients who take both gefitinib and platinum-based chemotherapy.

Abstract
AIM To investigate the role of maternal gestational weight gain (GWG) and prepregnancy BMI on programming offspring DNA methylation. METHODS Among 589 adult (age = 32) women participants of the Jerusalem Perinatal Study, we quantified DNA methylation in five candidate genes. We used inverse probability-weighting and parametric g-formula to estimate direct effects of maternal prepregnancy BMI and GWG on methylation. RESULTS Higher maternal GWG, but not prepregnancy BMI, was inversely related to offspring ABCA1 methylation (β = -1.1% per quartile; 95% CI: -2.0, -0.3) after accounting for ancestry, parental and offspring exposures. Total and controlled direct effects were nearly identical suggesting included offspring exposures did not mediate this relationship. Results were robust to sensitivity analyses for missing data and model specification. CONCLUSION We find some support for epigenetic programming and highlight strengths and limitations of these methods relative to other prevailing approaches.

Abstract
BACKGROUND Calls for evidence-informed public health policy, with implicit promises of greater program effectiveness, have intensified recently. The methods to produce such policies are not self-evident, requiring a conciliation of values and norms between policy-makers and evidence producers. In particular, the translation of uncertainty from empirical research findings, particularly issues of statistical variability and generalizability, is a persistent challenge because of the incremental nature of research and the iterative cycle of advancing knowledge and implementation. This paper aims to assess how the concept of uncertainty is considered and acknowledged in World Health Organization (WHO) policy recommendations and guidelines. METHODS We selected four WHO policy statements published between 2008-2013 regarding maternal and child nutrient supplementation, infant feeding, heat action plans, and malaria control to represent topics with a spectrum of available evidence bases. Each of these four statements was analyzed using a novel framework to assess the treatment of statistical variability and generalizability. RESULTS WHO currently provides substantial guidance on addressing statistical variability through GRADE (Grading of Recommendations Assessment, Development, and Evaluation) ratings for precision and consistency in their guideline documents. Accordingly, our analysis showed that policy-informing questions were addressed by systematic reviews and representations of statistical variability (eg, with numeric confidence intervals). In contrast, the presentation of contextual or "background" evidence regarding etiology or disease burden showed little consideration for this variability. Moreover, generalizability or "indirectness" was uniformly neglected, with little explicit consideration of study settings or subgroups. CONCLUSION In this paper, we found that non-uniform treatment of statistical variability and generalizability factors that may contribute to uncertainty regarding recommendations were neglected, including the state of evidence informing background questions (prevalence, mechanisms, or burden or distributions of health problems) and little assessment of generalizability, alternate interventions, and additional outcomes not captured by systematic review. These other factors often form a basis for providing policy recommendations, particularly in the absence of a strong evidence base for intervention effects. Consequently, they should also be subject to stringent and systematic evaluation criteria. We suggest that more effort is needed to systematically acknowledge (1) when evidence is missing, conflicting, or equivocal, (2) what normative considerations were also employed, and (3) how additional evidence may be accrued.

Abstract
Recently, ethicists have posited that consideration of epigenetic mechanisms presents novel challenges to concepts of justice and equality of opportunity, such as elevating the importance of environments in bioethics and providing a counterpoint to gross genetic determinism. We argue that new findings in epigenetic sciences, including those regarding intergenerational health effects, do not necessitate reconceptualization of theories of justice or the environment. To the contrary, such claims reflect a flawed understanding of epigenetics and its relation to genetics that may unintentionally undermine appeals to social justice. We provide a brief summary of epigenetic sciences, focusing on phenomena central to the current ethical discourse. We identify three fallacious modes of reasoning arising from the emergent literature on the ethical and policy implications of epigenetics, including mischaracterization, undue extrapolation, and exceptionalism. We end by discussing how these issues may work against mobilizing health equity policies and present a more modest claim regarding the value of new epigenetic knowledge to health justice by setting this discourse within the context of known themes in biomedical ethics and health policy.

Abstract
Objective: To investigate the effect of obstructive sleep apnea (OSA) on sleep architecture in acute ischemic stroke (AIS) patients. Methods: Seventy AIS patients with polysomnography examination from June 2014 to April 2016 were included in the Second Affiliated Hospital of Soochow University. Twenty-seven healthy controls during the same period were chosen as control group. According to apnea-hypopnea index (AHI), AIS patients were divided into AIS group (AHI<5/h) and AIS+ OSA group (AHI≥5/h). Their general conditions, Neurological function defect (national institutes of health stroke scale, NIHSS) on admission and at discharge and self-care ability (modified Rankin Scale, mRS) at discharge and 3 months later (mRS score <2 reflected good prognosis, and mRS score≥2 reflected unfavorable prognosis) were collected. Results: Fifty-two patients (74.3%) had OSA in total seventy AIS patients. Total sleep time (TST) was significantly shorter and sleep efficiency (SE) was lower in AIS group than the control group (P=0.007, 0.008, respectively). AIS+ OSA group had longer non-rapid eye movement (NREM)1 than control group [24.9(21.3) vs 14.3(10.6), P=0.044]. Compared with AIS group, AIS+ OSA group had shorter NREM3 [13.0(13.2) vs 19.6(12.8), P=0.039]. There was no significant difference between the infarct location of AIS group and AIS+ OSA group. However, AIS+ OSA group had higher mRS score observed at 3 months through follow-up visit than AIS group (P=0.027). Spearman correlation analysis showed a positive correlation between unfavorable prognosis of stroke at 3 months and atrial fibrillation, the oxygen desaturation index (ODI), percentage of oxygen saturation <90% of total recording time (TS90%), AHI, the longest time of apnea and hypopnea, respiratory related microarousal and NIHSS, while a negative correlation between unfavorable prognosis of stroke and NREM3, lowest nocturnal oxygen saturation (L-SaO(2)). On Logistic analysis, the unfavorable prognosis was independently predicted by AHI and NIHSS. Conclusions: Sleep architecture of cerebral infarction patients are disturbed with its characteristic of shorter total sleep time and lower sleep efficiency. Cerebral infarction patients with OSA have longer NREM1 and shorter NREM3.

Abstract
Objective: To explore the risk factors for lung cancer-related cerebral infarction. Methods: The hospitalized active lung cancer patients on anti-cancer therapy with no traditional stroke risk factors, who experienced an acute cerebral infarct in the First Affiliated Hospital of Guangxi Medical University from January 2005 to December 2015, were consecutively collected as the LCRS (lung cancer-related stroke) group. The active lung cancer patients without cerebral infarction hospitalized at the same peroid matched with the LCRS group for age and gender were collected as the LC (lung cancer) group. Clinical data from the two groups were analyzed. Results: A total of 139 LCRS patients and 139 LC patients were enrolled in the study, with 110 male and 29 female in each group, and there were no significant difference for the mean age between the LCRS group (52.1±10.4 years old ) and the LC group (52.1±10.1 years old). Two or more acute ischemic lesions of the brain were showed by MRI in most patients in the LCRS group (117 cases, 84.2%). Compared with the LC group, more patients in the LCRS group were found with adenocarcinoma, metastasis, elevated plasma D-dimer, CA125 and CA199 levels [88 cases (63.3%) vs 47 cases (33.8%); 98 cases (70.5%) vs 56 cases (40.3%); (468.38±291.37) μg/L vs (277.59±191.22) μg/L; (221.42±146.34) U/ml vs (106.84±69.97) U/ml; (254.68±185.84) U/ml vs (97.15±63.64) U/ml; with all P<0.001]. By logistic regression analysis of multiple factors, the elevated plasma D-dimer, CA125 and CA199 levels were showed to be independent risk factors for the cerebral infarction (OR=1.003, 95%CI 1.001-1.004; OR=1.006, 95%CI 1.003-1.010; OR=1.011, 95%CI 1.007-1.015). Conclusions: The elevated plasma D-dimer, CA125 and CA199 levels are the risk factors for the lung cancer related cerebral infarction, which may lead to hypercoagulation and induce cerebral infarction eventually.

Abstract
A large degree of polarization (ρ) of photoluminescence (PL) approximate to 1 is obtained in each nonpolar a-plane MgxZn1-xO layer grown by plasma-assisted molecular beam epitaxy (MBE) with x=0.01, 0.03, and 0.10, respectively. Anisotropic in-plane strains are selectively introduced by using foreign substrates and doping with different Mg contents, which strongly modify the valence band structures, leading to anisotropic optical properties. A polarized Raman measurement shows that anisotropic in-plane strains along the y and z axes increase with the increasing Mg contents. Polarized PL spectra show that ρ gradually increases to 0.97 with decreasing in-plane strains, resulting from an increasing difference in transition energy (ΔE) between E⊥c and E‖c caused by a lift of the degeneracy of valence band structures. The obtained highly polarized emission is close to linear polarized light, which is desirable in the backlighting of liquid crystal displays.

Abstract
Recent studies suggest that epigenetic programming may mediate the relationship between early life environment, including parental socioeconomic position, and adult cardiometabolic health. However, interpreting associations between early environment and adult DNA methylation may be difficult because of time-dependent confounding by life-course exposures. Among 613 adult women (mean age = 32 years) of the Jerusalem Perinatal Study Family Follow-up (2007-2009), we investigated associations between early life socioeconomic position (paternal occupation and parental education) and mean adult DNA methylation at 5 frequently studied cardiometabolic and stress-response genes (ABCA1, INS-IGF2, LEP, HSD11B2, and NR3C1). We used multivariable linear regression and marginal structural models to estimate associations under 2 causal structures for life-course exposures and timing of methylation measurement. We also examined whether methylation was associated with adult cardiometabolic phenotype. Higher maternal education was consistently associated with higher HSD11B2 methylation (e.g., 0.5%-point higher in 9-12 years vs. ≤8 years, 95% confidence interval: 0.1, 0.8). Higher HSD11B2 methylation was also associated with lower adult weight and total and low-density lipoprotein cholesterol. We found that associations with early life socioeconomic position measures were insensitive to different causal assumption; however, exploratory analysis did not find evidence for a mediating role of methylation in socioeconomic position-cardiometabolic risk associations.
