Evaluation of macular and choroidal thickness in healthy residents living at high altitude.

Purpose:Assessment of long-term effects of high altitude on choroidal thickness.Methods:This prospective cross-sectional study included 88 and 79 age- and sex-matched healthy individuals who were living at sea-level (SL group) and high-altitude (HA group), respectively. Participants were required to have resided in the same place for at least 10 years. Spectral-domain optical coherence tomography (SD-OCT) scans were conducted in two different and were performed within the same time (08:00 am to 10:00 am). Central macular thickness (CMT) and choroidal thickness were measured at five different points (i.e., at the central fovea and 1 mm and 2 mm temporal and nasal of the fovea). Blood hemoglobin (Hb), red blood cell (RBC), hematocrit (Htc) levels, blood oxygen saturation, heart rate, and body mass index (BMI) were compared between groups statistically.Results:The HA group had a mean age of 47.5 ± 13.3 years, whereas the SL group was 48.7 ± 13.4 years (P = 0.57). There was no significant difference between the groups in terms of CMT. Subfoveal choroidal thickness (SCFT) was 282.73 ± 87.82 mm in the HA group and 310.49 ± 74.73 in the SL group (P = 0.02). The choroid was found to be thinner at all the measured locations in the HA group except the 2 mm nasal point of the fovea. However, only the difference at an SFCT was statistically significant. Furthermore compared with the SL group statistically significant higher Hb, RBC, Htc levels were determined in the HA group. In the multiple linear regression model analysis, age was found an only effective confounder factor for SCFT (P = 0.001, 95% CI 4.132–2.476).Conclusion:The systemic adaptive changes due to chronic high altitude exposure may cause structural changes in the choroidal vascular network. The current study results revealed significant thinning only at SFCT. Large-scale longitudinal studies are needed to obtain more definitive data on this subject.

A comprehensive assessment of the performance of China’s provincial zero-waste cities and impact factor diagnosis

The large disparities in resource endowment and economic development in different regions have caused large differences in promoting zero-waste (ZW) cities. This study comprehensively considers the whole life cycle chain of solid waste and the guarantee mechanism for promoting the development of ZW cities, and constructs an index system from four dimensions: solid waste reduction at the source, solid waste resource utilization, solid waste final disposal, and development of security capacity. Furthermore, it adopts the TOPSIS–entropy weight method to evaluate the development status of ZW cities in 31 provinces, autonomous regions, and municipalities under the Central Government of China from 2010 to 2019 (Hong Kong, Macao, and Taiwan were excluded due to lack of data). The results show an upward trend of ZW levels in twenty-five provinces; a downward trend in four provinces, namely, Fujian, Heilongjiang, Jilin, and Liaoning; and a roughly f lat trend in two provinces, namely Henan, and Ningxia. Yunnan, Gansu, and Guizhou provinces have the most significant improvement in the ZW levels. Meanwhile, the eastern region has the highest ZW level, followed by the central and western regions. Combined with Geographic Information System (GIS), the solid waste management capacity of each region was analysed on the basis of the aforementioned four dimensions. Spatial differences were determined in the solid waste management characteristics of different regions. In terms of source reduction, the central and a few western regions have the best performance. Furthermore, the final disposal in the north is higher than that in the south, and the resourcefulness and development of security capacity show a clear decreasing trend from the east to west. Using a multiple linear regression analysis model, we analysed the potential factors affecting the ZW level of each region from four aspects: economy, technology, resource endowment, and education. The results indicated significant differences in the role of the same type of index in the ZW levels in each region. This paper assessed the performance of China’s ZW cities from both temporal and spatial perspectives, and the relevant influencing factors were further examined. It can provide a theoretical support and decision-making basis for China to improve ZW level further, narrow down the regional gaps, and implement green development and high-quality economic transformation, with important theoretical and practical values.

Pocket-sized sensor for controlled, quantitative and instantaneous color acquisition of plant leaves

The color of plant leaves can be assessed qualitatively by color charts or after processing of digital images. This pilot study employed a novel pocket-sized sensor to obtain the color of plant leaves. In order to assess its performance, a color-dependent parameter (SPAD index) was used as the dependent variable, since there is a strong correlation between SPAD index and greenness of plant leaves. A total of 1,872 fresh and intact leaves from 13 crops were analyzed using a SPAD-502 meter and scanned using the Nix™ Pro color sensor. The color was assessed via RGB and CIELab systems. The full dataset was divided into calibration (70% of data) and validation (30% of data). For each crop and color pattern, multiple linear regression (MLR) analysis and multivariate modeling [least absolute shrinkage and selection operator (LASSO), and elastic net (ENET) regression] were employed and compared. The obtained MLR equations and multivariate models were then tested using the validation dataset based on r, R2, root mean squared error (RMSE), and mean absolute error (MAE). In both RGB and CIELab color systems, the Nix™ Pro color sensor was able to differentiate crops, and the SPAD indices were successfully predicted, mainly for mango, quinoa, peach, pear, and rice crops. Validation results indicated that ENET performed best in most crops (e.g., coffee, corn, mango, pear, rice, and soy) and very close to MLR in bean, grape, peach, and quinoa. The correlation between SPAD and greenness is crop-dependent. Overall, the Nix™ Pro color sensor was a fast, sensible and an easy way to obtain leaf color directly in the field, constituting a reliable alternative to digital camera imagery and associated image processing.

Longitudinal impact of a poverty simulation on healthcare practitioners' attitudes towards poverty

BackgroundMany clinicians have limited knowledge about the challenges of living in poverty, leading to stigma and differential treatment in healthcare settings. A poverty simulation event may help clinicians gain empathy and knowledge about the ways that poverty impacts health and well-being. PurposeThis study evaluated the impact of a poverty simulation and the effect of personal characteristics on clinicians' attitudes towards poverty. MethodsUsing a prospective longitudinal mixed-methods study design, a convenience sampling of clinicians from a freestanding children's hospital was recruited to participate in a poverty simulation event. The 21-item Attitudes Towards Poverty (ATP) tool was administered pre- and post-simulation and at 3 follow-up time points. Multiple linear regression analysis and linear mixed effects models were used to analyze ATP data. Qualitative data were analyzed to identify broad themes. ResultsMean scores in the ATP domains of stigma and structural perspective increased post-simulation, but only stigma scores demonstrated sustained improvement. Scores in the personal deficiency domain remained unchanged. Being male, White, and having Liberal political views were associated with lower ATP scores in our data. Qualitative data show participants felt the simulation generated feelings of compassion and empathy. DiscussionSimulation participation improved ATP scores in two domains immediately post-event, suggesting the simulation positively impacted clinicians' attitudes towards poverty. Follow-up data suggest the impact of the simulation may be temporary. Translation to health education practiceExperiential learning activities, like poverty simulations, help foster awareness and empathy among clinicians but may not have long-term impact. Ongoing education is needed to create a workforce sensitized and equipped to care for families from all backgrounds.
