Abstract
PURPOSE Abdominal hernia (AH) is one of the most common clinical diseases. A large number of observational studies have found that obesity is an important risk factor for AH. However, the causal relationship between obesity and AH cannot be determined because of the clinical studies on AH induced by obesity are relatively few and only have some small- or medium-scale observational studies. Observational studies have so many confounding factors and reverse causality due to their shortcomings. From an evidence-based medicine perspective, they are not sufficiently convincing. Therefore, there is still a lack of high-quality, evidence-based medical evidence supporting a causal relationship between obesity and AH. A causal relationship between obesity and AH is also almost impossible to confirm by randomized controlled trials (RCTs). Our study based on Mendelian randomization (MR) may provide a higher level of evidence-based medical support for the relationship between obesity and AH. Body mass index (BMI) is the most common measure used for defining obesity. Finally, we employed two-sample Mendelian randomization (TSMR) to explore the causal relationship between BMI and AH. METHODS AH-related single nucleotide polymorphisms (SNPs) data were obtained from the FinnGen Biobank (FB), and BMI-related single nucleotide polymorphisms (SNPs) data were obtained from the UK Biobank (UKB). Genetic loci are used as instrumental variables (IVs), methods such as inverse variance weighted (IVW) were used for two-sample Mendelian randomization analysis, and the odds ratio (OR) value was used to evaluate the causal relationship between BMI and AH. RESULTS The results of the horizontal pleiotropy test were calculated by Egger-intercept method: p = 0.34 > 0.05. The Cochran Q test of MR-Egger method and IVW method showed heterogeneity P = 0.03 < 0.05, so the IVW random effect model was used as the gold standard. We found a genetically determined 1-standard deviation (SD) increment of BMI causally increased a 66.0% risk of AH (N = 371 SNPs, OR = 1.66, 95% CI 1.46-1.89, p = 1.55E-14) based on the IVW random effect model which was almost consistent with the results of other seven methods. CONCLUSIONS Our MR found genetic evidence for BMI and AH. The risk of developing AH increases with the number of BMI. This finding provides further evidence that maintaining a healthy BMI can prevent the development of AH. In addition, clinicians may need to focus on the potential risk of AH on some high-BMI patients.

Abstract
Abstract
BACKGROUND
While socioeconomic factors for racial disparities amongst sporadic meningioma patients have been explored, other potential influences are poorly understood. We sought to identify whether the genomic make-up is different amongst meningioma patients of different races and how they correlate with clinical variables.
METHODS
All patients who underwent surgery for sporadic meningioma and consented for whole exome sequencing were eligible. Genomic and clinical data were reviewed and analyzed.
RESULTS
537 intracranial meningiomas from 483 patients with the following racial profile were included: 75% White, 14% Black, 8% Latinx, 3% Asian. Compared with others, Whites were older at the time of diagnosis (p = 0.038) and surgery (p = 0.015). Black and Latinx patients were more likely to present with vision abnormalities (p = 0.006). Whites were more likely to have convexity meningiomas (p = 0.003), while Blacks were more likely to have tumors along the anterior fossa (p = 0.002) with associated somatic Hedgehog (HH) driver mutations (p = 0.008). Both Black and Latinx patients were more likely to have TRAF7 mutated meningiomas (p = 0.006). The highest number of copy number variations was seen in Blacks (p = 0.011) and this correlated with Blacks being more likely to have high-grade tumors, followed by Whites, Asians, and then Latinx (p = 0.020). Black patients trended toward decreased progression-free survival than others (median survival: 57 vs. 130 months; p = 0.06) despite similar extent of resection.
CONCLUSION
Overall, when mutational subgroup and location are considered, Black patients are more likely to have anterior skull base meningiomas with associated visual issues and corresponding somatic HH and TRAF7 mutations. With regards to tumor grade, Blacks harbor more aggressive sporadic meningiomas with a larger prevalence of high-grade meningiomas and associated underlying chromosomal instability compared to others. These findings have implications for meningioma care especially in minority populations, who may harbor more aggressive tumors.

Abstract
Abstract
INTRODUCTION
Approximately 50% of sporadic meningiomas, which originate throughout the neuroaxis, harbor bi-alleic NF2 loss. We sought to determine whether NF2 mutant meningiomas originating from different intracranial locations relative to the tentorium differ with regards to their genomic profile and clinical behavior.
METHODS
Clinical and whole exome sequencing data (WES) for all patients who underwent resection of NF2 mutant meningiomas and consented to WES were reviewed and analyzed.
RESULTS
258 NF2 mutant meningiomas were included and subdivided into supra- (sNF2) versus infra-tentorial (iNF2) groups (230 versus 28, respectively). Supratentorial location was significantly associated with genomically unstable tumors (percent genome altered median 12% vs. 1%, p< 0.001) and were more likely to harbor the more aggressive feature of chromosome 1p deletion (31.4% vs. 8.3%, p= 0.036). These malignant genomic features correlated with an increased incidence of high risk clinical features, including higher-grade (i.e. WHO Grade II/III) (48.9% vs. 7.14%, p < 0.001) and elevated Ki-67 (58.9% vs. 16.6%, p< 0.01), as well as larger volume (median 26.21 cm3 vs. 9.84 cm3, p< 0.001) and edema (65.8% vs. 25.9%, p= 0.001) in sNF2 meningiomas as compared with iNF2 tumors, respectively. Not surprisingly, although there was no difference in extent of resection between the groups (gross total resection (GTR), 96.26% vs. 96.15%, p= 0.45), patients with sNF2 tumors had more associated deaths (14.6% vs. 0%, p= 0.03) and a marginally shorter overall survival (p= 0.061). GTR was associated with longer progression-free survival (p= 0.037).
CONCLUSION
Within the homogeneous group of somatic NF2 mutated meningiomas, infratentorial tumors are seemingly more benign in their genomic make-up and clinical manifestation as compared to ones located in the supratentorial location. While GTR is useful to both groups in preventing recurrence, this benefit may be especially important in the clinically and genomically higher risk sNF2 tumors.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14445. [PMID: 36361324 PMCID: PMC9657604 DOI: 10.3390/ijerph192114445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 09/29/2022] [Accepted: 09/30/2022] [Indexed: 06/16/2023]
Abstract
Motor vehicle crashes (MVC) cause over three million people to be nonfatally injured each year in the United States alone. We investigated trends and patterns in prescription opioid usage among nonfatal MVC injuries in 50 states in the US and the District of Columbia from 2014 to 2018. All emergency department visits for an MVC event (N = 142,204) were identified from the IBM® MarketScan® Databases. Using log-binomial regression models, we investigated whether the prevalence of prescription opioids in MVC injuries varied temporally, spatially, or by enrollees' characteristics. Adjusting for age, relationship to the primary beneficiary, employment status, geographic region, and residence in metropolitan statistical area, the prevalence decreased by 5% (95% CI: 2-8%) in 2015, 18% (95% CI: 15-20%) in 2016, 31% (95% CI: 28-33%) in 2017, and 49% (95% CI: 46-51%) in 2018, compared to 2014. Moreover, the prevalence decreased by 28% (95% CI: 26-29%) after the publication of the CDC Guidelines for Prescribing Opioids for Chronic Pain. Spatial variations were observed in the prevalence and temporal trend of prevalence. The decreasing trend in the prevalence of prescription opioids in MVC is consistent with the decrease in the dispensing rate of opioids and the percentage of high-dosage opioids in the study population.

Abstract
The effect of intra-operative mechanical ventilation modes on pulmonary outcomes after thoracic surgery with one-lung ventilation has not been well established. We evaluated the impact of three common ventilation modes on postoperative pulmonary complications in patients undergoing lung resection surgery. In this two-centre randomised controlled trial, 1224 adults scheduled for lung resection surgery with one-lung ventilation were randomised to one of three groups: volume-controlled ventilation; pressure-controlled ventilation; and pressure-control with volume guaranteed ventilation. Enhanced recovery after surgery pathways and lung-protective ventilation protocols were implemented in all groups. The primary outcome was a composite of postoperative pulmonary complications within the first seven postoperative days. The outcome occurred in 270 (22%), with 87 (21%) in the volume control group, 89 (22%) in the pressure control group and 94 (23%) in the pressure-control with volume guaranteed group (p = 0.831). The secondary outcomes also did not differ across study groups. In patients undergoing lung resection surgery with one-lung ventilation, the choice of ventilation mode did not influence the risk of developing postoperative pulmonary complications. This is the first randomised controlled trial examining the effect of three ventilation modes on pulmonary outcomes in patients undergoing lung resection surgery.

Abstract
Glycosaminoglycans (GAGs) have high negative charge and are biologically and pharmaceutically important because their high charge promotes a strong interaction with many proteins. Due to the inherent heterogeneity of GAGs, multiple oligosaccharides, containing certain common domains, often can interact with clusters of basic amino acid residues on a target protein. The specificity of many GAG-protein interactions remains undiscovered since there is insufficient structural information on the interacting GAGs. Herein, we establish a cluster sequencing strategy to simultaneously deduce all major sequences of the affinity GAG oligosaccharides, leading to a definition of the consensus sequence they share that corresponds to the specific binding domain for the target protein. As a proof of concept, antithrombin III-binding oligosaccharides were examined, resulting in a heptasaccharide domain containing the well-established anticoagulant pentasaccharide sequence. Repeating this approach, a new pentasaccharide domain was discovered corresponding to the heparin motif responsible for binding interferon-γ (IFNγ). Our strategy is fundamentally important for the discovery of saccharide sequences needed in the development of novel GAG-based therapeutics.

Abstract
Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ2=4.16, P=0.041) and group C2 (χ2=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ2=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

Abstract
BACKGROUND AND OBJECTIVES Although polychlorinated biphenyls (PCBs) were banned decades ago, populations are continuously exposed to PCBs due to their persistence and bioaccumulation/biomagnification in the environment. Results from limited epidemiologic studies linking PCBs to thyroid cancer have been inconclusive. This study aimed to investigate the association between individual PCBs and PCB mixture and papillary thyroid cancer (PTC), the most common thyroid cancer histologic subtype. METHODS We carried out a nested case-control study including 742 histologically confirmed PTC cases diagnosed in 2000-2013 and 742 individually matched controls among U.S. military service members. Pre-diagnostic serum samples that were collected on average nine years before PTC diagnosis were used to measure PCB congeners by gas chromatography isotope dilution high resolution mass spectrometry (GC/ID-HRMS). Conditional logistic regression, Bayesian kernel machine regression (BKMR), and weighted quantile sum (WQS) regression were employed to estimate the association between single PCB congeners as well as their mixture and PTC. RESULTS Four PCB congeners (PCB-74, PCB-99, PCB-105, PCB-118) had significant associations and dose-response relationships with increased risk of PTC in single congener models. When considering the effects from all measured PCBs and their potential interactions in the BKMR model, PCB-118 showed positive trends of association with PTC. Increased exposure to the PCB congeners as a mixturewas also associated with an increased risk of PTC in the WQS model, with the mixture dominated by PCB-118, followed by PCB-74 and PCB-99. One PCB congener, PCB-187, showed an inverse trend of association with PTC in the mixture analysis. DISCUSSION This study suggests that exposure to certain PCBs as well as a mixture of PCBs were associated with an increased risk of PTC. The observed association was mainly driven by PCB-118, and to a lesser extent by PCB-74 and PCB-99. The findings warrant further investigation.

Abstract
Heparin (HP) is a polysaccharide that is widely used in the clinic as an anticoagulant. A major side effect associated with HP is the heparin-induced thrombocytopenia (HIT), which is initiated by the immune response to complex formed by HP and platelet factor 4 (PF4). Low molecular weight heparins (LMWHs) are the depolymerized version of HP, which have reduced risks of inducing HIT. However, it is still necessary to evaluate the immunogenicity of LMWHs to ensure their drug safety. Since HIT involves very complicated processes, the evaluation of HP and LMWH immunogenicity requires experiments from multiple aspects, of which the binding affinity between HP and PF4 is a key property to be monitored. Herein, we developed a novel competitive biolayer interferometry (BLI) method to investigate the binding affinity between HP and PF4. The influence of different domains in HP on its immunogenicity was compared for better understanding of the molecular mechanism of HP immunogenicity. Furthermore, the half maximal inhibitory concentration (IC50) of HP and LMWH can be measured by competitive combination, which is important for the quality control during the developing and manufacturing of HP and LMWH drugs.

Abstract
This study aimed to better understand the relationship between the street environment and walking behavior by deciphering the pedestrians' street environment preference based on their route choice behavior while walking. The route data of 219 residents were collected using an unobtrusive tracking method and subjected to binary logistic regression models to analyze the pedestrian route choice behavior. The results revealed that except for the walking distance, the trip purpose and travel status are the potential factors influencing the route choice of pedestrians. Furthermore, it was revealed that on-street parking, garbage bins, and streetlights could influence the pedestrians to select longer distance routes. In addition, pedestrians were more likely to select the shortest distance route when they were engaged in leisure activities with an accompanist. The findings of this study would offer insights, from different perspectives, into the micro-scale street environment and the walking behavior of pedestrians.

Abstract
Objective: To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China. Methods: Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use. Results: Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol (OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol (OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased (OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased (OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant (P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient (P<0.01). Conclusion: For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

Differences in self-perception of productivity and mental health among the STEMM-field scientists during the COVID-19 pandemic by sex and status as a parent: A survey in six languages. PLoS One 2022; 17:e0269834.

Abstract
The COVID-19 pandemic has caused unprecedented challenges for working conditions for scientists, but little is known for how the associations of these challenges with scientists’ mental health and productivity differ by sex and status as a parent. This online survey study in six languages collected data from 4,494 scientists in Science, Technology, Engineering, Mathematics, and Medicine fields across 132 countries during October–December 2021. We compared the type of challenges for work, changes in work hours, and perception in productivity during the pandemic by sex and status as a parent (children <18 years living at home). Regression analyses analyzed the impacts of changed working conditions and work-life factors on productivity and mental health. We found that the percentage of participants with increased work hours was the highest in female participants, especially without children. Disproportionately higher increases in work hours were found for teaching and administration in women than men and for research/fundraising in non-parent participants than parent participants (p-value<0.001). Female participants were more concerned about the negative impacts of the pandemic on publications and long-term career progress, and less satisfied with their career progress than their male counterparts. There were differences in the type of institutional actions for the pandemic across study regions. The identified obstacles for work and home-life factors were associated with higher risks of experiencing depression, anxiety, and stress. Decision makers should consider the gender differences in the pandemic’s adverse impacts on productivity in establishing equitable actions for career progress for scientists during pandemics.

Abstract
Abstract
Study question
Does a history of SARS-CoV-2 vaccination (CoronaVac) in males influence male fertility, gamete and embryo development, and in vitro fertilization (IVF) outcomes?
Summary answer
CoronaVac vaccination in males may not have an adverse effect on patient’s performance or the gamete and embryonic development potential during ART treatments.
What is known already
Vaccines against COVID-19 have been approved for emergency use in several countries and regions, while concerns about the potential negative effect of vaccines on fertility contributed to vaccine hesitancy. It is urgent to explore the effect of CoronaVac on human fertility to help to overcome vaccine hesitancy about possible fertility impairment.
Study design, size, duration
A retrospective cohort study enrolled couples undergoing IVF cycles between June and August 2021 at Reproductive Medicine Centre, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. According to the history of SARS-CoV-2 vaccination in males, the participants were divided into the vaccination group and the non-vaccination group.
Participants/materials, setting, methods
A self-controlled study of semen analyses for males before and after CoronaVac vaccination was conducted. Baseline characteristics were matched using propensity score matching. Participants were categorized into the unexposed group (non-vaccination) and exposed group (vaccination), and the population was 271 for each. Semen parameters and IVF outcomes were the main outcomes.
Main results and the role of chance
Generally, no statistically significant differences were exhibited between the matched cohorts regarding embryo developmental parameters, including fertilization rate, cleavage rate, high-quality embryo rate, blastocyst formation rate, and available blastocyst rate, as well as clinical outcomes, such as implantation rate, biochemical pregnancy rate, and clinical pregnancy rate. Moreover, males after vaccination seemed to have fluctuated semen parameters including increased semen volume, lower motility, and decreased normal forms of sperms, while the motile sperm counts were similar. In addition, all semen parameters were above the lower reference limits.
Limitations, reasons for caution
It was a single-center retrospective cohort study with a small sample size, and the men enrolled were suffering from infertility, which limited the generalizability of the conclusions. In addition, the endpoint of the current is a confirmation of clinical pregnancy, a study with a longer period of follow-up was urgent.
Wider implications of the findings
Our findings suggested that CoronaVac vaccinations in males may not have adverse effects on patient’s performance or the gamete and embryonic development potential during ART treatments. Larger studies among a wider population with longer follow-up in the future are required to support and validate our observations.
