Background: Despite the fact that 1-year graft and recipient survival rates are above 90% in most transplant centers, improving long-term graft survival remains an important challenge. Immunosuppressant nonadherence has been recognized as one of the important risk factors for long-term graft failure. Understanding the modifiable correlates and risk factors for medication non-adherence is essential to develop interventions to improve adherence and thus long-term transplantation outcomes.

Background: Ambient air pollution might serve as a prognostic factor for ovarian cancer (OC) survival, yet the relationships between plant-based diet indices (PDIs) and OC survival remain unclear. We aimed to investigate the associations of comprehensive air pollution and PDIs with OC survival and explored the effects of air pollution-diet interactions.

Methods: The present study encompassed 658 patients diagnosed with OC.

Introduction: Many challenges remain for long-term survival of renal allografts. Once-daily sirolimus (SRL) combined with low-dose extended-release tacrolimus (LER-TAC) may improve medication adherence and reduce the potential nephrotoxicity of calcineurin inhibitors (CNI) compared with standard immunosuppression regimens, thus potentially improving long-term graft survival.

Methods: This retrospective, observational, single-center, propensity score matching (PSM) study compared conversion to SRL combined with low-dose ER-TAC and mycophenolic acid (MPA) combined with standard-dose TAC in kidney transplant recipients.

Healthy lifestyle might alleviate the socioeconomic inequities in health, but the extent of the joint and interactive effects of these two factors on dementia are unclear. This study aimed to detect the joint and interactive associations of socioeconomic status (SES) and lifestyle factors with incident dementia risk, and the underlying brain imaging alterations. Cox proportional hazards analysis was performed to test the joint and interactive associations.

Recent evidence advises particles with a diameter of 2.5 µm or less (PM) might be a prognostic factor for ovarian cancer (OC) survival. The oxidative balance score (OBS) incorporates diet-lifestyle factors to estimate individuals' anti-oxidant exposure status which may be relevant to cancer prognosis.

Article Synopsis
  • - This study examined the link between reduced lung function and cognitive brain health, focusing on whether poor lung function can predict dementia risk over time, independent of other factors.
  • - Researchers analyzed data from over 430,000 non-demented participants using lung function tests and found that decreased lung function is significantly associated with an increased risk of developing dementia, including Alzheimer's and Vascular Dementia.
  • - Key biological mechanisms were identified, including inflammation, oxygen levels, and changes in brain structure, indicating that maintaining good lung function could be an important factor in promoting healthy aging and preventing dementia.

Background: Air pollution induces neurotoxic reactions and may exert adverse effects on cognitive health. We aimed to investigate whether air pollutants accelerate cognitive decline and affect neurobiological signatures of Alzheimer's disease (AD).

Methods: We used a population-based cohort from the Chinese Longitudinal Healthy Longevity Survey with 31,573 participants and a 10-year follow-up (5878 cognitively unimpaired individuals in Chinese Longitudinal Healthy Longevity Survey followed for 5.

Article Synopsis
  • A study examined how sleep, physical activity, and sedentary behavior relate to dementia risk among 431,924 participants over a median follow-up of 9 years.
  • Findings revealed that each of these behaviors has a unique, non-linear relationship with dementia risk, including U-shaped patterns for sleep and J-shaped patterns for sedentary behavior.
  • The combination of 7 hours of sleep per day, moderate-to-high physical activity, and low-to-moderate sedentary behavior was linked to the lowest risk of dementia, suggesting that modifying these behaviors could help in reducing dementia risk.

The potential roles of solar ultraviolet radiation (UVR) as an environmental risk factor in inducing atopic dermatitis (AD) have not been well quantified. To determine the short-term associations between UVR and AD outpatient visits, we obtained daily outpatient visits of AD in Shanghai Skin Disease Hospital from 2013 to 2018. Data of hourly ground UVR were collected.

Multi-electron reaction can be regarded as an effective way of building high-energy systems (>500 W h kg). However, some confusions hinder the development of multi-electron mechanisms, such as clear concept, complex reaction, material design and electrolyte optimization and full-cell fabrication. Therefore, this review discusses the basic theories and application bottlenecks of multi-electron mechanisms from the view of thermodynamic and dynamic principles.

Human papillomavirus (HPV) infections are common sexually-transmitted diseases among reproductive-aged women with increasing concern. Until now, there are no prior study about the association between HPV infections and ambient air pollution. This study aimed to explore the relationship between short-term exposure to ambient pollutants and daily outpatient visits for HPV infections in China.

  • Menstrual disorders are prevalent among women of reproductive age, and this study focuses on the potential link between these disorders and air pollution in Xi'an, China.
  • The research analyzed outpatient data from 2010 to 2016 and found that increases in specific pollutants (PM and NO) were associated with higher rates of outpatient visits for menstrual issues, particularly in younger women.
  • This study is significant as it's the first to suggest a correlation between short-term air pollution exposure and menstrual disorders, highlighting the need for deeper exploration into air quality's effects on women's health.

We report a successful design and synthesis method for developing a graphene/mesoporous carbon (G@PE40-MC700) electrode materials from upcycled waste polyethylene (PE) plastic combined with graphene oxide (GO) and flame retardant by low-temperature carbonization at 700 °C. The G@PE40-MC700 exhibits a high surface area (1175 m g) and a considerable amount of mesopores (2.30 cm g), thus improved electrochemical performance in both symmetric and hybrid supercapacitors with wide voltage windows.

Because activated carbon is extensively used in supercapacitors, optimization of its precursors and synthetic strategies are crucial. Inspired by the rich sugar content of banana peel waste, which can be transformed through the respiration of yeast into alcohol with the release of CO , we developed an environmentally benign and highly efficient process for the production of renewable heteroatom-doped hierarchical porous carbon materials (yeast-treated banana-peel-based carbon, denoted as YBP) without any additional templates or activation agents. The resulting biologically activated carbon was characterized by near-edge X-ray absorption fine-structure spectroscopy, X-ray photoelectron spectroscopy, and other physical methods.

The behavior of two-dimensional (2D) materials for energy storage systems relates to their morphology and physicochemical properties. Although various 2D materials can be found in different fields, the open access of these materials has greatly hampered their practical applications, such as in lithium-sulfur (Li-S) batteries, where the soluble intermediates should be controlled. Here, we have developed a facile approach to prepare 2D ultrathin interconnected carbon fabrics (ICFs) with "bubble-like" morphology and abundant mesopores using a "blowing bubble" method.

The association between ambient temperature and acute exacerbation of chronic bronchitis (AECB) was still unknown. Therefore, we performed an epidemiological study in a large hospital of Shanghai to explore the relationship about temperature and outpatient visit for AECB. We adopted a quasi-Poisson generalized additive models and distributed lag nonlinear models to estimate the accumulative effects of temperature on AECB across multiple days.
