Published: July 2024

Abstract
This study explores the performance of a dense optical flow method in comparison to pattern-matching techniques for retrieving atmospheric motion vectors (AMVs) from water vapor images. Using high-resolution simulated datasets that represent various weather phenomena, we assess the performance of these methods across different weather regimes, time intervals, and pressure levels and quantify the uncertainties associated with retrieved winds. The optical flow algorithm consistently outperforms the feature matching approach. Notably, it produces wind speeds and AMVs that closely resemble the wind fields from the simulations, and unlike the feature matching algorithm, the optical flow algorithm exhibits consistent performance across different time intervals. In contrast, the feature matching approach yields vector fields that exhibit oversmoothing in certain areas and erratic behavior in others, while also producing less detailed, regionally constant speed maps. Furthermore, unlike feature matching, the optical flow method effectively calculates AMV near regions with missing data, generating a dense AMV field for every pixel in a pair of images. This superior performance and flexibility significantly influence the planning for future satellite missions aimed at retrieving atmospheric winds. As such, our work plays a critical role in determining the mission architecture and projected instrument performance for future atmospheric wind retrieval satellite missions. The study underscores the potential of the optical flow algorithm as a robust and efficient approach for atmospheric motion retrieval, thus contributing to advances in climate research and weather prediction.

Significance Statement
This research investigates the efficacy of two methods, optical flow and feature matching, for detecting atmospheric winds, referred to as atmospheric motion vectors, from satellite images of water vapor. Employing detailed simulated datasets that replicate real-world weather patterns, we found that optical flow consistently outperforms feature matching in various aspects. Notably, the optical flow method is not only more precise but also maintains its accuracy across different scenarios. These insights are critical for the design of future satellite missions focused on advancing our understanding of the atmosphere and enhancing weather predictions. This study contributes to advancements in climate research and supports improved weather forecasting, benefiting both scientific and societal needs.

Published: July 2024

Abstract
Background
The epidemiology and risk factors for postoperative complications related to free flap reconstruction in head and neck cancer patients admitted to the Intensive Care Unit (ICU) are unknown.

Methods
We performed a retrospective cohort study of patients with free flap reconstruction of head and neck cancer between September 2015 and April 2023 admitted to the ICU of Beijing Tongren Hospital. The univariate and multivariate analyses were used to explore the risk factors for postoperative complications related to free flap reconstruction admitted to ICU, including flap necrosis, bleeding, fistula, and infection.

Results
A total of 239 patients were included in this study, and 38 (15.9%) patients had postoperative complications related to free flap reconstruction. The median length of ICU stay was 1 day (interquartile range, 1–2 days). Multivariate analysis found that low BMI (P < 0.001), high postoperative CRP (P = 0.005), low hemoglobin (P = 0.012), and inadequate fluid intake (P < 0.05) were independent risk factors for complications.

Conclusions
Postoperative complications related to free flap reconstruction were common in this ICU population. Careful fluid management and monitoring of CRP and hemoglobin levels may reduce complications.

Abstract
Introduction
Mortality due to injuries disproportionately impact low income countries. Knowledge of who is at risk of poor outcomes is critical to guide resource allocation and prioritization of severely injured. Kampala Trauma Score (KTS), developed in 1996 and last modified in 2002 as KTS II, is still widely being used to predict injury outcomes in resource-limited settings with no further revisions in the past two decades, despite ongoing criticism of some of its parameters. The New Trauma Score (NTS), a recent development in 2017, has shown potential in mortality prediction, but a dearth of evidence exist regarding its performance in the African population.

Objectives
To compare NTS to the modified Kampala Trauma Score (KTS II) in the prediction of 30-day mortality, and injury severity amongst patients sustaining road traffic crashes in Ugandan low-resource settings.

Methods
Multi-center prospective cohort study of patients aged 15 years and above. Of the 194 participants, 85.1% were males with a mean age of 31.7 years. NTS and KTS II were determined for each participant within 30-minutes of admission and followed-up for 30 days to determine their injury outcomes. The sensitivity, specificity, and area under receiver operating characteristics curve (AUC) for predicting mortality were compared between the two trauma scores using SPSS version 22. Ethical clearance: Research and Ethics Committee of Kampala International University Western Campus (Ref No: KIU-2022-125).

Results
The injury severity classifications based on NTS vs. KTS II were mild (55.7% vs. 25.8%), moderate (29.9% vs. 30.4%), and severe (14.4% vs. 43.8%). The mortality rates for each injury severity category based on NTS vs. KTS II were mild (0.9% v 0%), moderate (20.7% vs. 5.1%), and severe (50% vs. 28.2%). The AUC was 0.87 for NTS (95% CI 0.808–0.931) vs. 0.86 (95% CI 0.794–0.919) for KTS II respectively. The sensitivity of NTS vs. KTS II in predicting mortality was 92.6% (95% CI: 88.9–96.3) vs. 70.4% (95% CI: 63.0-77.8) while the specificity was 70.7% (95% CI: 64.2–77.2) vs. 78.4% (95% CI: 72.1–84.7) at cut off points of 17 for NTS and 6 for KTS II respectively.

Conclusions
NTS was more sensitive but its specificity for purposes of 30-day mortality prediction was lower compared to KTS II. Thus, in low-resourced trauma environment where time constraints and pulse oximeters are of concern, KTS II remains superior to NTS.

Authors: Bahramy Mohammad Ali , Hashempour Zahra , Shahriarirad Reza 
Published: July 2024

Abstract
Background
Severe post-vaccination neurological complications are rare. Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is an immune-mediated polyneuropathy affecting the peripheral nerve roots, which is not well described as a post-vaccination side effect. Here, we present a rare complication of vaccination against SARS-CoV-2, reaching a diagnosis of CIDP.

Case presentation
A 67-year-old diabetic male presented with lower extremity paresthesia and weakness following the third dose of the Sinopharm (BBIBP-CorV) vaccine. Despite initial dismissal as a diabetic complication, symptoms escalated, affecting all extremities. Electromyography study revealed abnormal spontaneous activity with chronic reinnervation changes, which was more significant in the lower extremities. Based on the clinical course, radiographic imaging, and laboratory data, a diagnosis of CIDP with severe axonal demyelinating features was established. Treatment with intravenous immunoglobulin (IVIg), prednisolone, and azathioprine resulted in marked improvement of the upper extremities but limited recovery in distal lower extremity muscles.

Conclusion
Although CIDP is a rare complication following COVID-19 vaccination, it should be considered in the differential diagnosis. Timely diagnosis of vaccine-induced CIDP is challenging, and any delay can adversely affect treatment response in affected patients.

Published: July 2024

Abstract
Introduction
Gestational diabetes, as a disorder of carbohydrate metabolism, is considered one of the most common metabolic complications in pregnancy. The diagnosis of diabetes in pregnancy leads to changes in lifestyle, and the treatments employed can affect various aspects of pregnant women’s lives, including their quality of life. The present study aimed to investigate the relationship between self-efficacy and the mediating effect of illness acceptance on the quality of life in pregnant women diagnosed with diabetes during pregnancy.

Materials and methods
This cross-sectional study was conducted on 240 pregnant women diagnosed with diabetes who were selected by convenience sampling method. Quality of life tools (SF12), the Acceptance of Illness Scale (AIS), and the Sherer self-efficacy scale were used to collect data.

Results
The mean (SD) of quality of life, self-efficacy, and disease acceptance were 57.36 (6.63), 51.75 (7.44), and 29.07 (7.69), respectively. In the single-variable regression analysis, self-efficacy and disease acceptance variables could predict 20.6% (β = 0.457, P < 0.001) and 14.4% (β = 0.385, P < 0.001) of the variations in quality of life, respectively. In the multiple regression model, by entering the two main variables (self-efficacy and Acceptance of Illness), demographic characteristics, three disease knowledge variables, health status from an individual perspective, and type of treatment, the variables could explain 25% of the changes of the quality of life (R2adj 0.25, P < 0.001=). Income status and self-efficacy had the highest impact among the variables. According to the results of path analysis, the total effect of self-efficacy on the quality of life of pregnant women with diabetes was 0.711.

Conclusion
The overall quality of life in women with diabetes was moderate, and self-efficacy, illness acceptance, and income status were predictors of overall quality of life. Self-efficacy can influence the quality of life by affecting disease acceptance. The findings highlight the importance of designing educational programs and providing midwifery services to increase self-efficacy and illness acceptance to improve the quality of life of pregnant women with diabetes.

Published: July 2024

Abstract
Objectives
HIV-infected individuals are at increased risk of neurocognitive disorders compared with the general population. Studies suggest that, despite the combination of antiretroviral drugs, HIV infection causes immune activation leading to significant neural damage; however, there is little data on HIV-infected young people in our country.

Methodology
This is a comparative cross-sectional study conducted between November 2020 and March 2021 on two hundred and sixteen children aged 6–15 years, including 106 HIV-positive children and 108 healthy children. Cognitive performance was assessed using the Differential Ability Scale Second Edition (DAS-II).

Results
HIV-infected children showed lower cognitive scores than control children in the subtest group of verbal ability (82.1% vs. 43.5%); non-verbal ability (84.9% vs. 45.4%); spatial ability (79.2% vs. 21.3%) and generall conceptual ability (GCA) (88.7% vs. 43.5%). The children in the control group had significantly higher ability scores in the diagnostic tests and in school achievement, and the difference was statistically significant.

Conclusion
Cognitive impairment remains a significant complication in HIV-positive children, as suggested by low cognitive scores in more than half of our participants. This is an unresolved issue with implications for survival, quality of life and daily functioning in these children. It is important that clinicians are able to identify and manage these cognitive deficits.
The global burden, risk and inequality of maternal obstructed labor and uterine rupture from 1990 to 2019
Authors: Yan Mingxing , Li Hui , Zheng Xinye , Li Feng , Gao Chen , Li Liying 
Published: July 2024

Abstract
Background
Obstructed labor (OL) and uterine rupture (UR) are common obstetric complications. This study explored the burden, risk factors, decomposition, and health inequalities associated with OL and UR to improve global maternal health.

Methods
This was a cross-sectional analysis study including data on OL and UR from the Global Burden of Diseases, and Risk Factors Study (GBD) 2019. The main outcome measures included the number and age-standardized rate (ASR) of incidence, disability-adjusted life years (DALYs), prevalence, and deaths.

Results
The global burden of OL and UR has declined, with a decrease in incidence (number in 2019: 9,410,500.87, 95%UI 11,730,030.94 to 7,564,568.91; ASR in 2019: 119.64 per 100,000, 95%UI 149.15 to 96.21; estimated annual percentage change [EAPC] from 1990 to 2019: -1.34, 95% CI -1.41 to -1.27) and prevalence over time. However, DALYs (number in 2019: 999,540.67, 95%UI 1,209,749.35 to 817,352.49; ASR in 2019: 12.92, 95%UI 15.63 to 10.56; EAPC from 1990 to 2019: -0.91, 95% CI -1.26 to -0.57) and deaths remain significant. ASR of DALYs increased for the 10–14 year-old age group (2.01, 95% CI 1.53 to 2.5), the 15–19 year-old age group (0.07, 95% CI -0.47 to 0.61), Andean Latin America (3.47, 95% CI 3.05 to 3.89), and Caribbean (4.16, 95% CI 6 to 4.76). Iron deficiency was identified as a risk factor for OL and UR, and its impact varied across different socio-demographic indices (SDIs). Decomposition analysis showed that population growth primarily contributed to the burden, especially in low SDI regions. Health inequalities were evident, the slope and intercept for DALYs were − 47.95 (95% CI -52.87 to -43.02) and − 29.29 (95% CI -32.95 to -25.63) in 1990, 39.37 (95%CI 36.29 to 42.45) and 24.87 (95%CI 22.56 to 27.18) in 2019. Concentration indices of ASR-DALYs were − 0.2908 in 1990 and − 0.2922 in 2019.

Conclusion
This study highlights the significant burden of OL and UR and emphasizes the need for continuous efforts to reduce maternal mortality and morbidity. Understanding risk factors and addressing health inequalities are crucial for the development of effective interventions and policies to improve maternal health outcomes globally.

Authors: Tibebe Dessie , Ambelu G/ Hiwot , Kassa Yezbie 
Published: July 2024

Abstract
Background
The majority of existing industries in Ethiopia discharge untreated effluents into nearby water bodies, streams and open land. The wastewater generated by Gondar malt factory (GMF) was disposed freely and join a natural wetland implemented for the treatment of the wastewater. The objective of the study was to analyze and characterize wastewater from GMF and to evaluate the effectiveness of the wetland for the treatment purpose.

Methods
Different Physicochemical quality indicators (color, turbidity pH, temperature, Total Dissolved solids, Total Suspended solids, total solid, conductivity, alkalinity, hardness, nitrate, phosphate, sulfate, free chlorides, heavy metals-(Cd, Cr, Fe, Mn, and Pb)and Biological Oxygen Demand were measured according to the standard procedures. Data was analyzed using Statistical Package for Social Sciences (SPSS-25). Analysis of Variance (ANOVA) was used to find whether significant differences existed in the different sampling stations for the parameters studied. P value less than 0.05 was considered to show significant difference.

Results
The results of this study revealed that most of the quality indicators were improved in value after the water passed through the wetland except for alkalinity M, sulfite, Mn, temperature and pH. From ANOVA result, it was noted that there was a significant mean difference between the stations except for chromium, manganese and lead. The result showed that the wetland plays a great role in the removal of pollutants where the best performance was obtained at removal efficiency of 96.188% PO4HR,75.63% Nitrate,>99% Cl2, ammonia and nitrite 99.99%, 92.77% sulfate,84.36% Total hardness,87.43% color, and for others it is ranged between 30 and 60%.

Conclusion
the study concluded that GMF wetland was almost effective and had potential in treatment of the wastewater from the discharging facilities (especially for nutrients, alkalinity P, hardness, color and chloride). It is recommended that wetlands should be conserved and used as wastewater treatment facility.

Abstract
Background
Improving the public’s understanding of how regional and socioeconomic inequalities create and perpetuate inequalities in health, is argued to be necessary for building support for policies geared towards creating a more equal society. However, research exploring public perceptions of health inequalities, and how they are generated, is limited. This is particularly so for young people. Our study sought to explore young people’s lived experiences and understandings of health inequalities.

Methods
We carried out focus group discussions (n = 18) with 42 young people, aged 13–21, recruited from six youth organisations in England in 2021. The organisations were located in areas of high deprivation in South Yorkshire, the North East and London. Young people from each organisation took part in three interlinked focus group discussions designed to explore their (i) perceptions of factors impacting their health in their local area, (ii) understandings of health inequalities and (iii) priorities for change. Due to the Covid-19 pandemic, most discussions took place online (n = 15). However, with one group in the North East, we carried out discussions face-to-face (n = 3). Data were analysed thematically and we used NVivo-12 software to facilitate data management.

Results
Young people from all groups demonstrated an awareness of a North-South divide in England, UK. They described how disparities in local economies and employment landscapes between the North and the South led to tangible differences in everyday living and working conditions. They clearly articulated how these differences ultimately led to inequalities in people’s health and wellbeing, such as linking poverty and employment precarity to chronic stress. Young people did not believe these inequalities were inevitable. They described the Conservative government as prioritising the South and thus perpetuating inequalities through uneven investment.

Conclusions
Our study affords important insights into young people’s perceptions of how wider determinants can help explain the North-South health divide in England. It demonstrates young people’s contextualised understandings of the interplay between spatial, social and health inequalities. Our findings support calls for pro-equity policies to address the structural causes of regional divides in health. Further research, engaging young people in deliberative policy analysis, could build on this work.

Abstract
Background
Prolonged laparoscopic nephroureterectomy (LNU) for upper tract urothelial cancer (UTUC) can increase the frequency of intravesical recurrence after surgery. Therefore, it is important for urological surgeons to have knowledge on preoperative risk factors for prolonged LNU. However, few studies have investigated the risk factors for prolonged LNU. We hypothesized that the quantity of perirenal fat affects the pneumoretroperitoneum time (PRT) of retroperitoneal LNU (rLNU). This study aimed to investigate the preoperative risk factors for prolonged PRT during rLNU.

Methods
We reviewed the data of 115 patients who underwent rLNU for UTUC between 2013 and 2021. The perirenal fat thickness (PFT) observed on preoperative computed tomography (CT) images was used to evaluate the perinephric fat quantity. Preoperative risk factors for PRT during rLNU were analyzed using logistic regression models. The cutoff value for PRT was determined based on the median time.The cutoff values for fat-related factors influencing PRT were defined according to receiver operating characteristic curve analysis.

Results
The median PRT for rLNU was 182 min (interquartile range, 155–230 min). The cutoff values of posterior, lateral, and anterior PFTs were 15 mm, 24 mm, and 6 mm, respectively. Multivariate analysis revealed that a posterior PFT ≥ 15 mm (odds ratio [OR], 2.72; 95% confidence interval, 1.04–7.08; p = 0.0410) was an independent risk factor for prolonged PRT.

Conclusions
Thick posterior PFT is a preoperative risk factor for prolonged PRT during rLNU. For patients with UTUC and thick posterior PFT, surgeons should develop optimal surgical strategies, including the selecting an expert surgeon as a primary surgeon and the selecting transperitoneal approach to surgery or open surgery.
