Emissions were concentrated in the western and southeastern areas with emission intensities of >10 ton/grid, including Dezhou, Liaocheng, and Rizhao cities. During 1981-2018, isoprenoid emissions experienced a rapid increase from 12.0 to 351.7 Gg, at a rate of 11.20 Gg/yr. Isoprene had the highest enhancement rate of 10.72 Gg/yr. The most rapid increase was observed in the northwestern cities Dezhou and Liaocheng, and the southeastern cities Rizhao, at an average rate of >100 kg/yr, even >500 kg/yr in some areas. The high emissions and their continued increase should be considered when studying the prevention and control of regional air pollution and making policies in China.

There has been a notable increase in knowledge production on air pollution and human health.

To analyze the state of the art on the effects of air pollution on human health through a mapping review of existing systematic reviews and meta-analyses (SRs and MAs).

The systematic mapping review was based on the recommendations for this type of scientific approach in environmental sciences. The search was performed using PubMed, Web of Science, Scopus, Cinahl, and Cochrane Library databases, from their inception through June 2020.

Among 3401 studies screened, 240 SRs and MAs satisfied the inclusion criteria. Five research questions were answered. There has been an overall progressive increase in publications since 2014. The majority of the SRs and MAs were carried out by researchers from institutions in China, the US, the UK, and Italy. Most studies performed a meta-analysis (161). In general, the reviews support the association of air pollution and health outcomes, and analyzed the effects of outdoor air n has harmful effects on health, with a focus on respiratory and cardiovascular outcomes. Future studies should extend the analysis to psychological and social aspects influenced by air pollution.Pollen is a well-established trigger of asthma and allergic rhinitis, yet concentration-response relationships, lagged effects, and interactions with other environmental factors remain poorly understood. Smartphone technology offers an opportunity to address these challenges using large, multi-year datasets that capture individual symptoms and exposures in real time. We aimed to characterise associations between six pollen types and respiratory symptoms logged by users of the AirRater smartphone app in Tasmania, Australia. We analyzed 44,820 symptom reports logged by 2272 AirRater app users in Tasmania over four years (2015-2019). With these data we evaluated associations between daily respiratory symptoms and atmospheric pollen concentrations. We implemented Poisson regression models, using the case time series approach designed for app-sourced data. We assessed potentially non-linear and lagged associations with (a) total pollen and (b) six individual pollen taxa. We adjusted for seasonality and meteorology and tested for interactions with particulate air pollution (PM2.5). We found evidence of non-linear associations between total pollen and respiratory symptoms for up to three days following exposure. Mirdametinib inhibitor For total pollen, the same-day relative risk (RR) increased to 1.31 (95% CI 1.26-1.37) at a concentration of 50 grains/m3 before plateauing. Associations with individual pollen taxa were also non-linear with some diversity in shapes. For all pollen taxa the same-day RR was highest. The interaction between total pollen and PM2.5 was positive, with risks associated with pollen significantly higher in the presence of high concentrations of PM2.5. Our results support a non-linear response between airborne pollen and respiratory symptoms. The association was strongest on the day of exposure and synergistic with particulate air pollution. The associations found with Dodonaea and Myrtaceae highlight the need to further investigate the role of Australian native pollen types in allergic respiratory disease.

To assess whether a modified treatment ladder algorithm incorporating transcutaneous retrobulbar amphotericin B (TRAMB) for invasive fungal rhino-orbital sinusitis (IFROS) can reduce the risk of exenteration without compromising survival.

Retrospective, comparative clinical study with historical controls.

Fifty consecutive patients with biopsy-proven invasive fungal sinusitis and radiographic evidence of orbital involvement were evaluated at a single tertiary institution from 1999-2020. TRAMB was incorporated as part of the treatment algorithm in 2015. Demographics, underlying immune derangement, infective organism, ophthalmic examination, surgical care, and survival were compared in a quasi-experimental pre-post format, dividing patients into a pre-2015 group and a post-2015 group. Risk of exenteration and mortality were the primary outcomes.

Baseline characteristics did not differ significantly between the two groups. Nearly all patients underwent a surgical intervention, which most commonly was functional endoscopic sinus surgery with debridement. TRAMB was administered to 72.7% of the post-2015 group. Exenteration was more common in the pre-2015 group (36.4% vs. 9.1%; 95% CI [5.2, 48.8]; p = 0.014), while mortality was similar (40.0% vs. 36.7%; 95% CI [-22.1, 29.3]; p = 0.816). After adjusting for potential confounders, patients treated after 2015 were found to have lower risk of exenteration (RR 0.28; 95% CI [0.08, 0.99]; p = 0.049) and similar risk of mortality (RR 1.04; 95% CI [0.50, 2.16]; p = 0.919).

In comparison to historical controls, patients with IFROS who were treated with a modified treatment ladder algorithm incorporating TRAMB had a lower risk of disfiguring exenteration without an apparent increase in the risk of mortality.

To compare the accuracy of the Barrett toric calculator with and without posterior corneal astigmatism and the Kane toric calculator.

Retrospective cross-sectional study METHODS The study included a total of 79 eyes of 79 patients who underwent toric IOL insertion during uncomplicated cataract surgery by a single surgeon. Using vector analysis, the mean absolute prediction error, the standard deviation of the prediction error, and the percentage of eyes with a prediction error within ± 0.50 diopter (D), ± 0.75 D, and ± 1.00 D were calculated. The IOL Master 700 (Carl Zeiss Meditec AG, Jena, Germany) was used for measuring biometry including posterior corneal astigmatism. Main analysis was designed to provide the clinical outcomes with each formula using the postoperative keratometry values and the measured postoperative IOL axis. Real-world analysis was performed using the preoperative keratometry values and the intended IOL axis.

There was no significant difference in mean absolute prediction errors calculated with two versions of the Barrett toric formula (predicted posterior corneal astigmatism and measured posterior corneal astigmatism) and Kane toric formula (P > 0.
