Abstract
Objective: To analyze the possible fusion genes with high-throughput transcriptome sequencing in myeloid leukemia patients with normal karyotype. Methods: From May 2017 to January 2019, three cases of myeloid leukemia patients with normal karyotype and negative for common fusion genes from the First Affiliated Hospital of Nanchang University were selected as the research objects. The transcriptome sequencing of bone marrow mononuclear cells was performed by high-throughput gene sequencing technology. Defuse software was used to analyze the gene fusion sequence in the transcriptome data, reverse-transcription polymerase chain reaction (RT-PCR) and Sanger sequencing were used to verify the fusion gene with clear pathological significance. Results: All three patients were diagnosed with myeloid leukemia by clinical manifestations, bone marrow cell morphology, immunology, and histochemical staining. Cytogenetic tests showed normal chromosome karyotypes. Fluorescence in situ hybridization and RT-PCR were used to detect BCR-ABL1, PML-RARA, and other common fusion genes. The results were all negative. Transcriptome sequencing and fusion transcripts analysis revealed that these three patients carried rare fusion genes with clear pathological significance, which included BCR-FGFR1, CPSF6-RARG, and NUP98-RARG, respectively. Conclusion: Transcriptome sequencing can accurately analyze rare but pathologically significant fusion genes that may exist in myeloid leukemia patients with normal karyotypes.

Abstract
Purpose To understand the long term effect of COVID-19 on 1) heart transplant waitlist trends and on 2) heart transplant case numbers in the United States. Methods The number of new adult heart transplant waitlist additions and transplant procedures were obtained from the UNOS database. Our time frame includes the 52 weeks between September 3, 2019 and September 4, 2020. Temporal changes in waitlist additions and heart transplants were analyzed using interrupted time series analyses with two transition periods. The first transition from the pre-COVID to the post-COVID era was determined as the week of March 11, 2020, when the first state imposed stay-at-home orders. The second transition period was determined as the first state re-opening during the week of April 22, 2020. Results Weekly waitlist additions were decreasing at -0.19 additions per week (95% CI: -0.35 to -0.03, p=0.018) prior to the COVID-19 era, defined as before the week of March 11, 2020, with a significant decrease in weekly waitlist additions of -2.09 (95% CI: -2.44 to -1.73, p< 0.001) during the post-COVID-19 era and prior to the first state re-opening the week of April 22, 2020 (Figure A). Weekly waitlist additions increased at 2.16 additions per week (95% CI: 1.81 to 2.51, p<0.001) following the first state announcing re-opening the week of April 22, 2020. Weekly transplants were relatively unstable, although decreasing at -0.003 transplants per week (95% CI: -0.279 to 0.273, p=0.984) in the pre-COVID era, and were trending downward at -0.18 transplants per week (95% CI: -0.3702 to 0.0036, p=0.054) thereafter (Figure B). The number of transplants rebounded and increased significantly at 0.49 transplants per week (95% CI: 0.26 to 0.72, p<0.001) after April 22, 2020. Conclusion The number of heart transplants and waitlist additions decreased significantly due to COVID-19 and rebounded following the first US state reopening the week of April 22, 2020. Waitlist additions continue to rise past levels observed during the pre-COVID era.

Phylogenetic diversity contributes more to sediment magnetism than abundance during incubation of iron-reducing sediment from a non-active volcanic lake in Northeast China. J Appl Microbiol 2021; 131:1813-1829. [PMID: 33772951 DOI: 10.1111/jam.15086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 01/18/2021] [Accepted: 03/22/2021] [Indexed: 12/01/2022]
Abstract
AIM This study aimed to analyse bacterial community and biomineralization products from Wudalianchi non-active volcanic field and the relationship between magnetization and bacterial community. METHODS AND RESULTS Eighteen sediment samples obtained from Wenbo Lake, high-throughput sequencing and quantitative PCR (qPCR) were separately employed to investigate the bacterial community composition dynamics and abundance variation of the sediment sample with the highest iron-reducing capacity during incubation. The mineralization products were characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction (XRD), Raman spectroscopy, vibrating sample magnetometer (VSM) and variable-temperature magnetism analyses. The results showed that the highest iron reduction rate was 98·06%. Seven phyla were identified as dominant bacterial phyla during the incubation process. Iron-reducing bacteria (FeRB) including Geobacter, Desulfosporosinus and Clostridium were involved in the iron mineralization process. The 16S rDNA copy numbers of sediment decreased quickly and then stayed steady during the incubation. Bacteria with rod-shaped and spheroid species were involved in extracellular iron reduction to produce magnetic particles with massive aggregation and columnar structures on the mineral surface morphologies. The materials produced by the microbial community over the incubation period were sequentially identified as siderite, magnetite and maghemite. The magnetism of the mineral samples gradually increased from 0·31748 to 33·58423 emu g-1 with increased incubation time. The final products showed relatively stable magnetism under 0-400 K. Meanwhile, the saturation magnetization (MS ) of the mineralized substance was tightly associated with bacterial diversity (P < 0·05). CONCLUSIONS Bacterial community varied during incubation of iron-reducing sediment of volcanic lake. Various iron mineral crystals were in turn formed extracellularly by FeRB. The magnetism of mineralized products was tightly associated with bacterial community. SIGNIFICANCE AND IMPACT OF THE STUDY These results not only help us to better understand the iron mineralization of FeRB in the volcanic lake sediments but also provide basic information for the future application of FeRB in environmental bioremediation.

Abstract
PURPOSE A multicentre prospective cohort study, known as the Chinese Pregnant Women Cohort Study (CPWCS), was established in 2017 to collect exposure data during pregnancy (except environmental exposure) and analyse the relationship between lifestyle during pregnancy and obstetric outcomes. Data about mothers and their children's life and health as well as children's laboratory testing will be collected during the offspring follow-up of CPWCS, which will enable us to further investigate the longitudinal relationship between exposure in different periods (during pregnancy and childhood) and children's development. PARTICIPANTS 9193 pregnant women in 24 hospitals in China who were in their first trimester (5-13 weeks gestational age) from 25 July 2017 to 26 November 2018 were included in CPWCS by convenience sampling. Five hospitals in China which participated in CPWCS with good cooperation will be selected as the sample source for the Chinese Pregnant Women Cohort Study (Offspring Follow-up) (CPWCS-OF). FINDINGS TO DATE Some factors affecting pregnancy outcomes and health problems during pregnancy have been discovered through data analysis. The details are discussed in the 'Findings to date' section. FUTURE PLANS Infants and children and their mothers who meet the criteria will be enrolled in the study and will be followed up every 2 years. The longitudinal relationship between exposure (questionnaire data, physical examination and biospecimens, medical records, and objective environmental data collected through geographical information system and remote sensing technology) in different periods (during pregnancy and childhood) and children's health (such as sleeping problem, oral health, bowel health and allergy-related health problems) will be analysed. TRAIL REGISTRATION NUMBER CPWCS was registered with ClinicalTrials.gov on 18 January 2018: NCT03403543. CPWCS-OF was registered with ClinicalTrials.gov on 24 June 2020: NCT04444791.

Abstract
There are minimal data regarding the prevalence of cancer in patients with coronavirus disease 2019 (COVID-19), as well as the incidence of severe illness and rate of mortality in COVID-19 patients with cancer. PubMed, Embase, Cochrane Library, and Web of Science were systematically searched, from database inception to July 15, 2020, for studies of patients with COVID-19 that included information regarding comorbid cancer. In total, 109 eligible global studies were included in this systematic review. Ninety studies with 94,845 COVID-19 patients, among which 4106 exhibited comorbid cancer, were included in the meta-analysis regarding prevalence of comorbid cancer. Twenty-three studies with 71,969 COVID-19 patients, among which 4351 with comorbid cancer had severe illness or death, were included in the meta-analysis. The overall prevalence of cancer among COVID-19 patients was 0.07 (95% CI 0.05–0.09). The cancer prevalence in COVID-19 patients was higher in Europe (0.22, 95% CI 0.17–0.28) than in the Asia-Pacific region (0.04, 95% CI 0.03–0.06) or North America (0.05, 95% CI 0.04–0.06). The cancer prevalence in COVID-19 patients aged >60 years was 0.10 (95% CI 0.07–0.14), while the prevalence among patients aged ≤60 years was 0.05 (95% CI 0.03–0.06). The pooled prevalence of severe illness among COVID-19 patients with cancer was 0.34 (95% CI 0.26–0.42) and the pooled mortality rate of COVID-19 patients with cancer was 0.20 (95% CI 0.16–0.25). Pooled incidences of severe illness among COVID-19 patients with cancer from Asia Pacific, Europe, and North America were 0.38 (95% CI 0.24–0.52), 0.39 (95% CI 0.25–0.53), and 0.26 (95% CI 0.20–0.31), respectively; pooled mortality rates from the Asia-Pacific region, Europe, and North America were 0.17 (95% CI 0.10–0.24), 0.26 (95% CI 0.18–0.35), and 0.19 (95% CI 0.13–0.25), respectively.

Abstract
The current evidence regarding the prevalence of subclinical carotid atherosclerosis (SCA) for people living with HIV(PLWH) is inconsistent. In this study, we aimed to synthesize data on the prevalence and association of SCA patients with HIV infection. We searched PubMed, EMBASE, Web of Science, Medline, SinoMed, and CNKI from inception to March 2, 2020. The pooled proportion, odds ratio (OR) with 95% confidence intervals (CIs) were calculated. For inclusion, SCA was measured by carotid intima-media thickness (CIMT), with a B-mode ultrasound machine. Twenty-six studies consisting of 6590 participants were identified. The overall prevalence of SCA was 31.6% (95% CI 13.4-53.3; I2 = 99%; 4 studies) according to CIMT ≥ 0.78 mm criteria, and 32.3% (19.6-46.4; 97%; 10 studies) according to CIMT ≥ 0.90 mm criteria. SCA prevalence was higher in Europe, over 40 years old and male. What's more, PLWH have a higher likelihood of developing SCA comorbidity than HIV-negative controls (pooled OR 2.66, 95% CI 1.57-4.50, I2 = 74%; 9 studies), even after sensitivity analysis (pooled OR 2.58, 1.54-4.31, 73%). This study suggests a high prevalence and risk of SCA in the global population with HIV. As a result, subclinical carotid atherosclerosis deserves more attention from policymakers, HIV health-care providers, researchers, and stakeholders.

Abstract
OBJECTIVES To investigate the association between frailty status and risk of fall among middle-aged and older Chinese people. DESIGN A nationally representative prospective cohort study. SETTING AND PARTICIPANTS The study included 13,877 community-dwelling participants aged 45 years and above from the China Health and Retirement Longitudinal Study. METHODS Frailty status was identified by the frailty index of health deficit accumulation. 34 variables at baseline were selected to calculate the frailty index. We excluded participants with incomplete information in construction of the frailty index at baseline. Falls were measured based on the respondents' self-report. We used a logistic regression model to estimate the associations between the frailty status and risk of fall, and subgroup analyses and sensitivity analyses were further conducted. RESULTS Of 13,877 participants, 2310 (16.6%) had falls during the observation period. 9027 (65.0%) participants were classified as robust, 4019 (29.0%) participants were classified as pre-frail, and 831 (6.0%) participants were classified as frail. Our results indicated per 0.01 increment in the frailty index was significantly associated with an increased risk of fall among middle-aged and older participants (OR: 1.52, 95%CI: 1.45-1.60). Such association was stronger when frailty was presented as a categorical variable, with an OR of 1.75 (95%CI: 1.59-1.93) for pre-frail and 3.04 (95%CI: 2.60-3.56) for frail. The area under the curve of the logistic model was 0.612 (95%CI: 0.600-0.625). Each 0.01 increment of the frailty index was association with a higher risk of fall among middle-aged (45-59years) participants (OR: 1.44, 95%CI: 1.29-1.60) than among older (≥60 years) participants (OR: 1.28, 95%CI: 1.16-1.41) at baseline (p=0.015 for interaction). CONCLUSION Frailty was significantly associated with an increased risk of fall among community-dwelling middle-aged and older people in China. It is necessary to screen and recognize frailty status to prevent falls among middle-aged and older adults.

The Software's of Excel 2010 and SPSS 23.0 were applied for data cleaning and statistical analysis on the population, time and area distributions of COVID-19 cases. Results: On January 22, 2020, the first confirmed case of COVID-19 was reported in Heilongjiang. By March 11, 2020, a total of 482 cases domestic case of COVID-19, The incidence rate was 1.28/100 000, the mortality rate was 2.70% (13/482) in 13 municipalities in Heilongjiang. There were 81 clusters of COVID-19, The number of confirmed cases accounted for 79.25% (382/482) of the total confirmed cases and 12 cases of deaths. The family clusters accounted for 86.42% (70/81). Compared with the sporadic cases, the mortality rate, proportion of elderly cases aged 60 or above and severe or critical cases of clinical classification were all higher in the clusters especially the family clusters, but the differences were not significant (P>0.05). There were 34 clusters involving more than 5 confirmed cases accounted for 41.98% (34/81) of the total clusters, the involved cases accounted for 68.31% (261/382) of the total cases of clusters. There were significant differences in age distribution of the cases among the case clusters with different case numbers. In the clusters involving 6-9 cases, the proportion of cases aged 65 years or above was more (26.53%, 39/147). Conclusions: The incidence rate of COVID-19 was relatively high and the early epidemic was serious in Heilongjiang, The number of cases was large in clusters especially family clusters.

Abstract
Management of posterior tibial plateau fractures has gained much interest over the past few years. Fracture morphology, trauma mechanism, and soft-tissue injury have been identified as the key factors determining the treatment strategy and outcome. We provide a rationale for the operative management of posterior tibial plateau fractures by discussing the interplay between fracture morphology, trauma mechanism, and soft-tissue injury. The trauma mechanism has proven to be an important tool, not only to understand fracture morphology, but also to assess concomitant soft-tissue (i.e. ligamentous) injury. Subsequently, soft-tissue injury might play a role in future classification and diagnostic work-up of tibial plateau fractures, particularly in fractures with posterior involvement. Plate osteosynthesis using a posterior approach is safe and should be considered routinely in coronal fractures of the posterior tibial plateau, as illustrated.

Abstract
Background This study aims to explore the relationships between pre-pregnancy body mass index (BMI), gestational weight gain (GWG), rate of GWG during the second and third trimesters (GWGrate) and birth weight among Chinese women. Methods Women were enrolled by 24 hospitals in 15 different provinces in mainland China from July 25th, 2017 to 26 November 2018. Pre-pregnancy BMI, GWG and GWGrate were calculated and divided in to different groups. The multinomial logistic regression model and restrictive cubic spline model were used to explore the relationships. Results Of the 3585 participants, women who were underweight, had insufficient GWG or GWGrate had 1.853-, 1850- or 1.524-fold higher risks for delivering small-for-gestational-age (SGA) infant compared with women who had normal BMI, sufficient GWG or GWGrate. Women who were overweight/obese, had excessive GWG or GWGrate had 1.996-, 1676- or 1.673-fold higher risks for delivering large-for-gestational-age (LGA) infant. The effects of GWG and GWGrate on birth weight varied by pre-pregnancy BMI statuses. Dose-response analysis demonstrated L-shaped and S-shaped relationships between pre-pregnancy BMI, GWG, GWGrate and neonatal birth weight. Conclusions Pre-pregnancy BMI, GWG or GWGrate were associated with neonatal birth weight among Chinese women. Both body weight before and during pregnancy should be maintained within the recommendations to prevent abnormal birth weight.

Abstract
AIM To investigate the association of dietary patterns with gestational depression and sleep disturbance. METHODS Women in early pregnancy were recruited from the Chinese Pregnant Women Cohort Study (CPWCS) through July 25th, 2017 to November 26th, 2018, and eventually 7615 participants were included in this study. The qualitative food frequency questionnaire (Q-FFQ), Edinburgh Postnatal Depression Scale (EPDS), and the Pittsburgh Sleep Quality Index (PSQI) were used to assess dietary, depression and sleep quality during pregnancy, respectively. Dietary patterns were derived by factor analysis. Logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (95% CI) of each outcome according to quartiles of each dietary pattern. RESULTS Five dietary patterns were identified. Participants with the highest quartile in plant-based pattern had a significantly lower likelihood of mental problems (OR: 95% CI for depression: 0.66, 0.55-0.79; sleep disturbance: 0.80, 0.68-0.93); Similar results were observed in vitamin-rich pattern (OR: 95% CI for depression: 0.46, 0.38-0.55; sleep disturbance: 0.76, 0.65-0.89); However, contrary results were found in high-fat pattern (OR: 95% CI for depression: 2.15, 1.25-1.85; sleep disturbance: 1.43, 1.22-1.67); In animal protein-rich pattern, participants with the highest quartile had a decreased likelihood of depression (OR: 0.80, 95% CI: 0.67-0.96). As for bean products pattern, participants with the highest quartile had an increased risk of depression (OR: 1.28, 95% CI:1.06-1.53). Interactions of dietary patterns and lifestyles on mental disorders were observed. CONCLUSION Dietary patterns were associated with gestational depression and sleep disturbance. Relevant departments and maternal and child health personnel should conduct health education for pregnant women and guide them to eat properly.

Abstract
Objective: To investigate the application value of molecular detection in the differential diagnosis of ovarian adult granulosa cell tumors (AGCT) by analyzing FOXL2, AKT1 and DICER1 mutations in these tumors. Methods: A total of 48 cases of ovarian sex cord-stromal tumor (SCST) were selected from July 2012 to June 2019 in Beijing Obstetrics and Gynecology Hospital, including 21 adult granulosa cell tumors (AGCT), 15 fibromas/fibrothecomas, 8 Sertoli-Leydig cell tumors (SLCT) and 4 other types of ovarian SCST. Genomic DNA was extracted from the formalin-fixed paraffin-embedded tissue sections. Polymerase chain reaction amplification for FOXL2, AKT1 and DICER1 genes was performed, followed by sequencing using capillary electrophoresis. Fisher exact test was used to compare the prevalence difference of FOXL2, AKT1 and DICER1 mutations among the groups. P<0.05 was considered significant. Results: Eighteen of the 21 (85.7%) AGCT harbored FOXL2 mutation. Compared with other SCST (13.0%, 3 of 23; including fibromas/fibrothecomas and SLCT), FOXL2 mutation was significantly higher in AGCT (P<0.001). In addition, FOXL2 mutation was also detected in one fibrothecoma, two SLCT and two gynandroblastomas. DICER1 mutation was identified in four of eight SLCT, and these cases were moderately to poorly differentiated. FOXL2 mutation was found in one SLCT with DICER1 mutation. There was no DICER1 mutation in other ovarian SCST. No AKT1 mutation was detected in all the patients. Conclusions: FOXL2 mutation is a highly specific biomarker for adult AGCT and may be helpful to resolve problematic cases. Diagnosis should also be taken into consideration of the clinical and histological features as FOXL2 mutation is also found in other SCST. The detection of DICER1 mutation is helpful for the differential diagnosis of ovarian SLCT. Synchronous DICER1 and FOXL2 mutation in the SLCT has been observed, and its significance needs to be further studied.

Effects of pre-pregnancy body mass index and gestational weight gain on maternal and infant complications. BMC Pregnancy Childbirth 2020; 20:390. [PMID: 32631269 PMCID: PMC7336408 DOI: 10.1186/s12884-020-03071-y] [Citation(s) in RCA: 127] [Impact Index Per Article: 31.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 06/19/2020] [Indexed: 02/06/2023] Open
Abstract
Background The potential effects of pre-pregnancy body mass (BMI) and gestational weight gain (GWG) on pregnancy outcomes remain unclear. Thus, we investigated socio-demographic characteristics that affect pre-pregnancy BMIs and GWG and the effects of pre-pregnancy BMI and GWG on Chinese maternal and infant complications. Methods 3172 women were enrolled in the Chinese Pregnant Women Cohort Study-Peking Union Medical College from July 25, 2017 to July 24, 2018, whose babies were delivered before December 31, 2018. Regression analysis was employed to evaluate the socio-demographic characteristics affecting pre-pregnancy BMI and GWG values and their effects on adverse maternal and infant complications. Results Multivariate logistic regression analysis revealed that age groups < 20 years (OR: 1.97), 25–30 years (OR: 1.66), 30–35 years (OR: 2.24), 35–40 years (OR: 3.90) and ≥ 40 years (OR: 3.33) as well as elementary school or education below (OR: 3.53), middle school (OR: 1.53), high school (OR: 1.40), and living in the north (OR: 1.37) were risk factors in maintaining a normal pre-pregnancy BMI. An age range of 30–35 years (OR: 0.76), living in the north (OR: 1.32) and race of ethnic minorities (OR: 1.51) were factors affecting GWG. Overweight (OR: 2.01) and inadequate GWG (OR: 1.60) were risk factors for gestational diabetes mellitus (GDM). Overweight (OR: 2.80) and obesity (OR: 5.42) were risk factors for gestational hypertension (GHp). Overweight (OR: 1.92), obesity (OR: 2.48) and excessive GWG (OR: 1.95) were risk factors for macrosomia. Overweight and excessive GWG were risk factors for a large gestational age (LGA) and inadequate GWG was a risk factor for low birth weights. Conclusions Overweight and obesity before pregnancy and an excessive GWG are associated with a greater risk of developing GDM, GHp, macrosomia and LGA. The control of body weight before and during the course of pregnancy is recommended to decrease adverse pregnancy outcomes, especially in pregnant women aged < 20 or > 25 years old educated below university and college levels, for ethnic minorities and those women who live in the north of China. Trial registration Registered at Clinical Trials (NCT03403543), September 29, 2017.

Abstract
The heat shock protein 70 (HSPA) family and their genes have been studied in ticks and are considered as possible antigen candidates for the development of anti-tick vaccines. However, knowledge about their members, structure and function in ticks is incomplete. Based on our transcriptomic data, the full length of four HSPA genes in Haemaphysalis flava (Acari: Ixodidae) was cloned via rapid amplification of cDNA ends. The open reading frame of HSPA2A, HSPA2B, HSPA5 and HSPA9 was 1920, 1911, 1983 and 2088 bp in length, respectively. Three family signatures and one localization motif were in the encoding proteins. HSPA2A and HSPA2B were predicted to be located at cytoplasm/nucleus, whereas HSPA5 and HSPA9 were at endoplasmic reticulum and mitochondria, respectively. In silico simulation demonstrated that those proteins had distinct numbers of α-helixes, extended strands and coils, and different antigenic epitopes. Expression of HSPA5 and HSPA9 in the salivary gland was significantly higher in partially-engorged female adult ticks than the fully-engorged (P < 0.01) as shown by a quantitative polymerase chain reaction. Our data indicated that H. flava ticks had at least four HSPA genes encoding proteins with different cellular locations, structures and expression profiles, suggesting their diverse roles in tick biology.

Abstract
BACKGROUND With the development of urbanization, there is a decreasing tendency for people contact with natural greenness. Whether maternal exposure to greenness has an impact on pregnancy complications and pregnancy outcomes remains to be confirmed. OBJECTIVES To estimate the association and dose-response relationship between residential greenness and pregnancy outcomes. DATA SOURCES PubMed, Embase, Ovid, Scopus and Web of Science from inception to 1st December 2019 were searched. SYNTHESIS METHODS The summary regression coefficient (β) and odds ratio (OR) with corresponding 95% confidence interval (95%CI) were calculated. The linear dose-response relationship between greenness and adverse pregnancy outcomes was also investigated. RESULTS Overall, 36 studies with a total of 11,983,089 participants were included. Birth weight was significantly higher in highest level of greenness exposure group compared to lowest level group (e.g. β:20.22, 95%CI:13.50-26.93 at 100 m buffer). The odds of low birth weight (LBW) decreased in the highest level of group compared to lowest level group (e.g. OR:0.86, 95%CI:0.75-0.99 at 100 m buffer). The odds of small for gestational age (SGA) also decreased in the highest group (OR:0.93, 95%CI:0.88-1.00 at 100 m buffer). In addition, maternal exposure to greenness was associated with increased head circumference and decreased mental disorders. The dose-response models showed a 2% decrease risk of LBW per 0.1 normalized difference vegetation index (NDVI) increase within 300 m buffer (OR:0.98, 95%CI:0.97-0.99, P < 0.001) and a 1% decrease risk of SGA per 0.1 NDVI increase within 300 m buffer (OR:0.99, 95%CI:0.98-1.00, P = 0.037). No significant associations were found on preterm birth, gestational age, gestational diabetes mellitus, gestational hypertension or preeclampsia. CONCLUSIONS This review confirms an inverse association between residential greenness and adverse pregnancy outcomes. Findings of our study provide evidences for pregnant women to increase greenness exposure.

Abstract
BACKGROUND AND PURPOSE Recent studies from the Alzheimer's Disease Neuroimaging Initiative show that, in the USA, 75% of patients with Alzheimer's disease are female. To date, there have rarely been any attempts to analyze data by sex or gender, which limits the potential for discovering the effects of sex or gender on disease. Little evidence is available regarding the effect of gender and apolipoprotein E (APOE) ε4 on white matter (WM) connection from the functional perspective due to the lack of appropriate techniques for detecting blood-oxygen-level-dependent signals in WM. METHODS We took advantage of a new framework known as functional tensor imaging to investigate the effect of sex and APOEε4 on WM cortical functional connectivity throughout the brain. RESULTS In a group of female patients with amnestic mild cognitive impairment, we found a significantly reduced functional connectivity in the left posterior limb of the internal capsule, left superior fronto-occipital fasciculus, bilateral temporopolar area and right somatosensory association cortex in APOEε4 carriers in contrast to non-carriers. We also found a significant APOEε4 by sex interaction effect on the right somatosensory association cortex, left temporopolar area and left superior temporal gyrus. The clinical Montreal Cognitive Assessment score was significantly negatively associated with the right somatosensory association cortex with APOEε4 by sex interaction in males. CONCLUSIONS These results indicate that increased APOE-related risk in women may be associated with decreased activity in both gray matter and WM in patients with amnestic mild cognitive impairment compared with men. The finding suggests accounting for sex differences in neuroimaging biomarkers, diagnostics and treatment strategy.
