ABSTRACT

Climatology and trends in different types of aerosols with focus on absorbing aerosols over Kanpur located in Indo-Gangetic Plain (IGP) in South Asia and Beijing in North China Plain (NCP) in East Asia are investigated. We perform a first analysis of high-quality time series of columnar aerosols observations over a period of nearly two-decades, along with satellite observations to provide a broader regional perspective. Satellite retrieved aerosol Ångström exponent (AE) values have increased (10-20%) suggesting an increasing contribution of fine aerosols to aerosol optical depth (AOD) over Asia in last 2-decades. Among three aerosol types [urban-industrial (UI), biomass burning (BB), and dust (DU)], only UI and BB aerosols are present over Kanpur throughout the year, while DU is present along with UI and BB aerosols only during pre-monsoon and monsoon. Overall, there is a positive trend in BB aerosols over both Kanpur and Beijing, a positive (negative) trend in UI aerosols over Kanpur (Beijing), and positive (negative) trend in dust over Beijing (Kanpur). Positive trend in BB aerosols over Kanpur is statistically significant. Among three absorbing aerosol types [mostly black carbon (MBC), mostly dust (MDU), and mixed (MIX) containing BC and dust], only MBC and MIX are present in post-monsoon and winter over IGP, and MDU is present along with MBC and MIX only during pre-monsoon and monsoon, in agreement with aerosol types found. Trends in MBC, MIX and MDU over Kanpur in IGP and in MIX over Beijing are statistically significant. These trends are attributed mainly to changes in anthropogenic aerosol emissions, and not to natural and climatic factors as their changes are relatively small. These findings on hitherto unavailable climatology and trends in aerosols and absorbing aerosols over two global aerosol hotspots and identified contrasts will be crucial in model simulations to better decipher aerosol-climate interactions over Asia.

ABSTRACT

BACKGROUND: Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) participates in the immune-related allergic response and inflammation flare, while its clinical role in asthma children is still unknown. Herein, this study aimed to investigate MALT1 expression, and its correlation with exacerbation risk, T helper (Th)1, Th2 cells (and their secreted cytokines), as well as inflammatory cytokines in asthma children.

METHODS: Sixty children with asthma exacerbation and 60 children with remission asthma were enrolled in this study; then their blood MALT1, Th1, Th2 cells, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interferon-gamma (IFN-γ), and interleukin-4 (IL-4) were detected. Besides, blood MALT1 in another 20 health controls was also determined.

RESULTS: Mucosa-associated lymphoid tissue lymphoma translocation protein 1 was highest in children with asthma exacerbation, followed by children with remission asthma, and lowest in health controls (p < 0.001). MALT1 could distinguish children with asthma exacerbation from children with remission asthma (area under the curve (AUC): 0.757, 95% CI: 0.670-0.843). In children with asthma exacerbation, MALT1 was negatively linked with IFN-γ (p = 0.002) and Th1 cells (p = 0.050), but positively related to Th2 cells (p = 0.027) and exhibited a positive correlation trend (without statistical significance) with IL-4 (p = 0.066); meanwhile, MALT1 was positively correlated with exacerbation severity (p = 0.010) and TNF-α (p = 0.003), but not linked with IL-6 (p = 0.096). In children with remission asthma, MALT1 only was negatively associated with Th1 cells (p = 0.023), but positively linked with TNF-α (p = 0.023).

CONCLUSION: Mucosa-associated lymphoid tissue lymphoma translocation protein 1 serves as a potential biomarker for monitoring exacerbation risk and Th1/Th2 imbalance-mediated inflammation of asthma children.

ABSTRACT

OBJECTIVES: To report the causative relationship of maternal COVID-19 with intrauterine fetal death, describe the specific placental pathology, findings of fetal autopsy and clinical characteristics, and identify potential risk factors.

METHODS: This is a prospective case series. A cohort of 165 placentas of non-vaccinated pregnant women affected by COVID-19 in Greece were histologically examined and six cases of intrauterine fetal death associated with SARS-COV-2 placentitis were retrieved. Complete fetal autopsy was performed in three cases. Gross, histopathological, immunohistochemical, molecular, and electron microscopy examinations were carried out in the stillbirth placentas and fetal organs. The histological findings of SARS-COV-2 placentitis were compared with the 159 cases, in which maternal COVID-19 resulted in livebirth. Regression analysis was used to identify predisposing factors for SARS-COV-2 placentitis.

RESULTS: All six stillbirth placentas showed severe and extensive histological changes of SARS-COV-2 placentitis, i.e. a combination of marked intervillositis with a mixed inflammatory infiltrate and massive perivillous fibrinoid deposition with trophoblast damage, associated with intensely positive immunostaining for SARS-COV-2 spike protein, the presence of virions on electron microscopy and a positive RT-PCR test in placental tissues. The histological lesions obliterated over 75% of the maternal intervillous space, accounting for intrauterine fetal death. Similar histological lesions affecting less than 25% of the placenta were recorded in 7 liveborn neonates, while the remaining 152 placentas of COVID-19-affected pregnancies with livebirths did not show similar findings. Complete fetal autopsy showed evidence of an asphyctic mode of death without evidence of viral transmission to the fetus. The mothers had mild clinical symptoms or were asymptomatic and the interval between maternal COVID-19 diagnosis and fetal death ranged from 3 to 15 days. Statistically significant predisposing factors for SARS-COV-2-placentitis included thrombophilia and IUGR. Multiple sclerosis was seen in one case.

CONCLUSIONS: SARS-COV-2 placentits occurred uncommonly in COVID-19-affected pregnancies of non-vaccinated mothers and, when extensive, caused fetal demise, with no evidence of transplacental fetal infection. Thrombophilia and prenatally detected IUGR emerged as independent predisposing factors for the potentially lethal SARS-COV-2 placentitis. This article is protected by copyright. All rights reserved.

ABSTRACT

OBJECTIVE: To describe the characteristics of women with stress or mixed urinary incontinence (SUI/MUI) receiving physical therapy (PT) services, including referral patterns and PT utilization.

METHODS: Female patients with claims associated with an SUI or MUI diagnosis (International Classification of Disease-Clinical Modification [ICD-9-CM]: 625.6, 788.33, or ICD-10-CM: N39.3, N39.46) between July 01, 2014 and June 30, 2016 were identified in International business machines (IBM)’s MarketScan Research Database. Inclusion criteria included the absence of pregnancy claims and ≥80% medical and pharmacy enrollment pre- and postindex. First SUI/MUI diagnosis claim determined index. Patients were followed for 2 years, and associated UI-associated PT encounters were identified. Descriptive statistics were calculated for patients with at least one PT visit during the postindex period.

RESULTS: In a cohort of 103,813 women with incident SUI or MUI diagnosis, 2.6% (2792/103,813) had at least one PT visit in the 2 years following their diagnosis. Mean age at index PT encounter was 50.55 years. A total of 52.36% (1462/2792) women had one to four PT visits; 21.2% (592/2792) had >8 PT visits. In subanalysis of the PT cohort (1345/2792), women who received PT only had the lowest average 2-year postindex total medical cost (mean: $12,671; SD: $16,346), compared with PT plus medications (mean: $27,394; SD: $64,481), and PT plus surgery (mean: $33,656; SD: $26,245), respectively. Over 40% had their first PT visit ≥3 months after their index date.

CONCLUSIONS: The percentage of women with a PT visit associated with an incident SUI or MUI diagnosis was low (2.6%), and 30% of this group completed three or more PT visits. This suggests poor adherence to clinical guidelines regarding supervised treatment of UI in women.

IMPACT STATEMENT: Our study suggests underutilization of PT among insured women with SUI and MUI in the 2 years following diagnosis. Interventions to improve this gap in first-line care may represent an opportunity for an increased role for PTs in the care of women with UI.

ABSTRACT

Exposure-response assessment methods have shifted towards more quantitative approaches, with health risk assessors exploring more statistically driven techniques. These assessments, however, usually rely on one critical health effect from a single key study. Categorical regression addresses this limitation by incorporating data from all relevant studies – including human, animal, and mechanistic studies – thereby including a broad spectrum of health endpoints and exposure levels for exposure-response analysis in an objective manner. Categorical regression requires the establishment of ordered response categories corresponding to increasingly severe adverse health outcomes, and the availability of a comprehensive database that summarizes all data on different outcomes from different studies, including the exposure or dose at which these outcomes are observed and their severity. It has found application in the risk assessment of essential nutrients and trace metals. Since adverse effects may arise from either deficient or excess exposure, the exposure-response curve is U-shaped, which provides a basis for determining optimal intake levels that minimize the joint risks of deficiency and excess. This article provides an overview of the use of categorical regression fit exposure-response models incorporating data from multiple evidence streams. An extension of categorical regression that permits the simultaneous analysis of excess and deficiency toxicity data is presented and applied to comprehensive databases on copper and manganese. Future applications of categorical regression will be able to make greater use of diverse data sets developed using new approach methodologies, which can be expected to provide valuable information on toxic responses of varying severity.

ABSTRACT

Cardiovascular reactions to acute psychological stress have been associated with cognitive function. However, previous work has assessed cardiovascular reactions and cognitive function in the laboratory at the same time. The present study examined the association between cardiovascular reactions to acute psychological stress in the laboratory and academic performance in final year high school students. Heart rate, blood pressure, stroke volume, and cardiac output reactions to an acute psychological stress task were measured in 131 participants during their final year of high school. Performance on high school A-levels were obtained the following year. Higher heart rate and cardiac output reactivity were associated with better A-level performance. These associations were still statistically significant after adjusting for a wide range of potentially confounding variables. The present results are consistent with a body of literature suggesting that higher heart rate reactions to acute psychological stress are associated with better cognitive performance across a variety of domains.

ABSTRACT

OBJECTIVES: This study aimed to evaluate the changes in knee pain, a dominant cause of physical disability, following the coronavirus disease (COVID-19) pandemic, and to identify factors affecting the changes in knee pain.

METHODS: We analyzed the pre- and post-COVID-19 longitudinal dataset of the Nagahama Study. Knee pain was assessed using the Knee Society Score (KSS). The estimated KSS from the age and sex using regression model in the pre- and post-COVID-19 dataset was compared. Factors including the activity score, educational level, and various impacts of COVID-19 were analyzed for correlation analyses with changes in KSS.

RESULTS: Data collected from 6409 participants showed statistically significant differences in KSS, pre- (mean = 22.0; SD = 4.4) and post-COVID-19 (mean = 19.5; SD = 6.4). Low activity score (p = 0.008), low educational level (p < 0.001) and undesirable financial impact (p = 0.030) were independently associated with knee pain exacerbation.

CONCLUSION: The harmful effects of the COVID-19 pandemic on knee pain were suggested. People should be encouraged to engage in physical activities, such as walking, even despite the state of emergency. Furthermore, social support for economically disadvantaged groups may improve healthcare access, preventing the acute exacerbations of knee pain.

ABSTRACT

ATTED-II (https://atted.jp) is a gene coexpression database for nine plant species based on publicly available RNAseq and microarray data. One of the challenges in constructing condition-independent coexpression data based on publicly available gene expression data is managing the inherent sampling bias. Here, we report ATTED-II version 11, wherein we adopted a coexpression calculation methodology to balance the samples using principal component analysis and ensemble calculation. This approach has two advantages. First; omitting principal components with low contribution rates reduces the main contributors of noise. Second; balancing large differences in contribution rates enables considering various sample conditions entirely. In addition, based on RNAseq- and microarray-based coexpression data, we provide species-representative, integrated coexpression information to enhance the efficiency of inter-species comparison of the coexpression data. These coexpression data are provided as a standardized z-score to facilitate integrated analysis with different data sources. We believe that with these improvements, ATTED-II is more valuable and powerful for supporting inter-species comparative studies and integrated analyses using heterogeneous data.

ABSTRACT

BACKGROUND: City-wide lockdowns and school closures have demonstrably impacted COVID-19 transmission. However, simulation studies have suggested an increased risk of COVID-19 related morbidity for older individuals inoculated by house-bound children. This study examines whether the March 2020 lockdown in New York City (NYC) was associated with higher COVID-19 hospitalization rates in neighborhoods with larger proportions of multigenerational households.

METHODS: We obtained daily age-segmented COVID-19 hospitalization counts in each of 166 ZIP code tabulation areas (ZCTAs) in NYC. Using Bayesian Poisson regression models that account for spatiotemporal dependencies between ZCTAs, as well as socioeconomic risk factors, we conducted a difference-in-differences study amongst ZCTA-level hospitalization rates from February 23 to May 2, 2020. We compared ZCTAs in the lowest quartile of multigenerational housing to other quartiles before and after the lockdown.

FINDINGS: Among individuals over 55 years, the lockdown was associated with higher COVID-19 hospitalization rates in ZCTAs with more multigenerational households. The greatest difference occurred three weeks after lockdown: Q2 vs. Q1: 54% increase (95% Bayesian credible intervals: 22-96%); Q3 vs. Q1: 48% (17-89%); Q4 vs. Q1: 66% (30-211%). After accounting for pandemic-related population shifts, a significant difference was observed only in Q4 ZCTAs: 37% (7-76%).

INTERPRETATION: By increasing house-bound mixing across older and younger age groups, city-wide lockdown mandates imposed during the growth of COVID-19 cases may have inadvertently, but transiently, contributed to increased transmission in multigenerational households.
