Published: December 2021

AbstractThis study aimed to reveal the characteristics of nutrients and heavy metals associated with ecological risks in the sediments of Fenhe River, Taiyuan section. The concentrations of nutrients (total nitrogen, total phosphorus, total organic matter) and heavy metals (As, Cu, Zn, Pb, Cr, Ni, Hg, Cd) were investigated. Spatial distribution, correlation analysis and source identification were facilitated to indicate nutrient and heavy metal pollution characteristics. Evaluations of heavy metals’ contamination degree were achieved by comprehensive ecological risk indexes including Igeo, Iin, Cf, pollution load index and risk index. The results showed that nutrients accumulated in the middle region and were mainly from embryophyte, zooplankton and phytoplankton or algae, based on C/N values. Large spatial variabilities existed in heavy metal distribution patterns; source identification for heavy metals revealed they were from natural sources and anthropogenic activities based on a principal component analysis model. Results of different ecological risk indexes showed that pollution associated with Hg was rated as a moderate ecological risk but was significant contamination, higher ecological risks mainly existed in the middle region.

Abstract
Furfural residue (FR), a solid waste, was applied as the precursor to prepare activated carbon by steam activation. The Box-Behnken design (BBD) approach-based response surface methodology (RSM) was utilized to optimize the preparation conditions to evaluate their effects on the performance of activated carbon from furfural residue (FRAC). The optimum preparation conditions of FRAC were found as follows: activation temperature of 922 °C, activation time of 62 min, and the mass ratio of char to H2O of 1:4.5, resulting in 1,501.84 mg/g of iodine adsorption capacity and 1,662.41 m2/g of specific surface area. The FRAC was characterized and then the adsorption performance of bisphenol S (BPS) on FRAC was investigated. Langmuir and Koble-Corrigan isotherm models were well fitted to the experimental data, and the adsorption kinetics process was perfectly described by the pseudo-second-order model. Thermodynamic parameters showed that the adsorption of BPS was a spontaneous exothermic process. Besides, the regeneration efficiency of FRAC was over 97% after five consecutive cycles. The maximum monolayer adsorption capacity of FRAC for BPS was 3.2848 mmol/g at 298 K, indicating that the FRAC was an excellent adsorbent for the removal of BPS from aqueous solutions.
Verão no aquário e Fazes-me falta: considerações sobre a escrita em Lygia Fagundes Telles e Inês Pedrosa

Published: December 2021

Este artigo objetiva dialogar os romances Verão no aquário, de Lygia Fagundes Telles, e Fazes-me falta, de Inês Pedrosa, na perspectiva da linguagem literária. Parte-se da hipótese de que esta categoria apresenta-se como errante e impotente para esclarecer o que diz, constatação que não é vista como problemática, apenas como composição do estilo peculiar das escritoras. Segundo a crítica, estes romances são significativos na consagração de ambas, consideração que se justifica, principalmente, pela irreverência da linguagem neles trabalhada. A análise foi fundamentada em contribuições voltadas ao estudo da literatura contemporânea, em especial, Maurice Blanchot (1997; 1987) e Roland Barthes (1984; 2011). Para compreender as acepções feitas pela crítica, foram consultados, dentre outros, os trabalhos de Diana Navas e Telma Ventura (2018); Sônia Régis (1998). Constatou-se que a linguagem, nestas obras, é entrelaçada à ideia de morte, tema presente nos dois enredos e que comunga com a escritura das autoras.

Introduction. The incorporation of combined positron emission tomography-computed tomography (PET-CT) into clinical practice has significantly expanded the understanding of the pathogenesis of many diseases. Evidence-based data on the diagnostic efficacy in infectious and inflammatory diseases is increasing, making this imaging method very promising. Purpose of the study. To study the diagnostic efficacy of 18F-FDG PET-CT in various chronic inflammatory diseases of kidneys and bladder.Materials and methods. A retrospective study of the results of whole-body 18F-FDG PET-CT in 45 patients was carried out. Patients underwent an investigation at various times after surgical treatment of localized oncology of the anogenital zone at the T1N0M0 stage without the involvement of the genitourinary system. It was found that 24 patients had a history of chronic pyelonephritis and 21 patients had manifestations of radiation cystitis. Repeated PET/CT scans were performed after a course of therapy for inflammatory urological diseases to assess the treatment results of the underlying pathology.Results. The latent course of chronic renal failure was accompanied by a diffuse decrease in 18F-FDG metabolism in the renal parenchyma with its partial recovery after etiotropic therapy and urine sanitation. Hypermetabolism of 18F-FDG was detected in the bladder wall during manifestations of radiation cystitis, which was leveled during therapy and relief of urinary syndrome manifestations. Bacterial and radiation inflammation differed in molecular-cell responses to the pathogen, while the results of urinalysis, indicating the effectiveness of the treatment, coincided with the visual and digital indicators of the restoration of adequate energy metabolism in the studied tissues.Conclusions. Metabolism of 18F-FDG in the kidneys and bladder can objectively reflect the nature of inflammation and complement the data on the effectiveness of the treatment.

Introduction. Lower urinary tract symptoms (LUTS) are common in men and are associated with a significant decrease in quality of life. To date, there is no universal approach to the treatment of LUTS, which determines the need to search for new methods for influencing the lower urinary tract.Purpose of the study. To test the hypothesis that the use of peripheral magnetic neuromodulation (PMN) in male patients with LUTS will reduce the severity of LUTS.Materials and methods. Sixty-eight men with LUTS were enrolled in a prospective, randomized study. Patients were randomized in a 1:1 ratio for PMN or drug therapy with an alpha-1-blocker (tamsulosin). The primary endpoint was a reduction the LUTS severity such as urinary frequency during the day, nocturia and urgency as assessed using the IPSS questionnaire and urination diary. Improvements in urodynamic parameters such as maximum urine flow rate (Q max), mean urine flow rate (Q ave), and residual urine volume (PVR) were the secondary endpoint of the study. The results were evaluated on equal terms (10 days and 1 month) in both groups.Results. Sixty-seven (98.5%) subjects were included in the final base. Ten days after the start of therapy in the magnetic stimulation group, symptom relief was noted by 21 people (61.7%), the mean IPSS score showed a decrease from 18.1 ± 2.1 to 16.9 ± 3.2 points (p = 0.037). The number of urinations per day decreased from 14 (6 - 20) to 10 (6 - 14) times (p < 0.001). Objective indicators of urodynamics did not change in both groups. At a period of 1 month, PMN occurred in 22 (64.7%) patients, the IPSS score was 16.6 ± 3.7 points (p = 0.032), the number of urinations 9 (6 - 14) times (p < 0.001). Objective indicators have not changed. In the tamsulosin group, IPSS score changed from 19.27 ± 5.08 to 15.4 ± 4.85 (p < 0.001), Q max 14.36 ± 2.82 ml/s increased to 15.94 ± 2.71 ml/s (p = 0.032), while the Q ave did not change (p = 0.17). The number of urinations decreased from 13 (6 - 19) times to 10 (6 - 14) times (p <0.001).Conclusion. The study demonstrated the promise of PMN in men with LUTS in terms of improving the quality of life. The proposed method may be preferable for patients dissatisfied with drug therapy. Further placebo-controlled studies are required to help determine the role of PMN in the management of patients with LUTS.
Personalized Reminders for Immunization Using Short Messaging Systems to Improve Human Papillomavirus Vaccination Series Completion: Parallel-Group Randomized Trial
Authors: Wynn Chelsea S , Catallozzi Marina , Kolff Chelsea A , Holleran Stephen , Meyer Dodi , Ramakrishnan Rajasekhar , Stockwell Melissa S 
Published: December 2021

Background
Completion rates among adolescents who initiate the human papillomavirus (HPV) vaccine 3-dose series are low. SMS text message vaccine reminders are effective, but less is known about the best types for HPV series completion or the ability to assess and target vaccine decision-making stage.

Objective
The aim of this study is to compare the effectiveness of HPV vaccine series completion in minority adolescents who received precision and educational versus conventional SMS text message reminders.

Methods
Enrolled parents of adolescents aged 9-17 years who received the first HPV vaccine dose at 1 of the 4 academic-affiliated community health clinics in New York City were randomized 1:1 to 1 of the 2 parallel, unblinded arms: precision SMS text messages (which included stage-targeted educational information, next dose due date, and site-specific walk-in hours) or conventional SMS text messages without educational information. Randomization was stratified according to gender, age, and language. The primary outcome was series completion within 12 months. In post hoc analysis, enrollees were compared with concurrent nonenrollees and historical controls.

Results
Overall, 956 parents were enrolled in the study. The precision (475 families) and conventional (481 families) SMS text message arms had similarly high series completion rates (344/475, 72.4% vs 364/481, 75.7%). A total of 42 days after the first dose, two-thirds of families, not initially in the preparation stage, moved to preparation or vaccinated stage. Those in either SMS text message arm had significantly higher completion rates than nonenrollees (708/1503, 47.1% vs 679/1503, 45.17%; P<.001). Even after removing those needing only 2 HPV doses, adolescents receiving any SMS text messages had higher completion rates than historical controls (337/2823, 11.93% vs 981/2823, 34.75%; P<.001). A population-wide effect was seen from 2014 to 2016, above historical trends.

Conclusions
SMS text message reminders led to timely HPV vaccine series completion in a low-income, urban, minority study population and also led to population-wide effects. Educational information did not provide an added benefit to this population.

A Novel Deep Learning–Based System for Triage in the Emergency Department Using Electronic Medical Records: Retrospective Cohort Study
Authors: Yao Li-Hung , Leung Ka-Chun , Tsai Chu-Lin , Huang Chien-Hua , Fu Li-Chen 
Published: December 2021

Background
Emergency department (ED) crowding has resulted in delayed patient treatment and has become a universal health care problem. Although a triage system, such as the 5-level emergency severity index, somewhat improves the process of ED treatment, it still heavily relies on the nurse’s subjective judgment and triages too many patients to emergency severity index level 3 in current practice. Hence, a system that can help clinicians accurately triage a patient’s condition is imperative.

Objective
This study aims to develop a deep learning–based triage system using patients’ ED electronic medical records to predict clinical outcomes after ED treatments.

Methods
We conducted a retrospective study using data from an open data set from the National Hospital Ambulatory Medical Care Survey from 2012 to 2016 and data from a local data set from the National Taiwan University Hospital from 2009 to 2015. In this study, we transformed structured data into text form and used convolutional neural networks combined with recurrent neural networks and attention mechanisms to accomplish the classification task. We evaluated our performance using area under the receiver operating characteristic curve (AUROC).

Results
A total of 118,602 patients from the National Hospital Ambulatory Medical Care Survey were included in this study for predicting hospitalization, and the accuracy and AUROC were 0.83 and 0.87, respectively. On the other hand, an external experiment was to use our own data set from the National Taiwan University Hospital that included 745,441 patients, where the accuracy and AUROC were similar, that is, 0.83 and 0.88, respectively. Moreover, to effectively evaluate the prediction quality of our proposed system, we also applied the model to other clinical outcomes, including mortality and admission to the intensive care unit, and the results showed that our proposed method was approximately 3% to 5% higher in accuracy than other conventional methods.

Conclusions
Our proposed method achieved better performance than the traditional method, and its implementation is relatively easy, it includes commonly used variables, and it is better suited for real-world clinical settings. It is our future work to validate our novel deep learning–based triage algorithm with prospective clinical trials, and we hope to use it to guide resource allocation in a busy ED once the validation succeeds.

Published: December 2021

Background
Tanzania introduced District Health Information Software (version 2; DHIS2) in 2013 to support existing health management information systems and to improve data quality and use. However, to achieve these objectives, it is imperative to build human resource capabilities to address the challenges of new technologies, especially in resource-constrained countries.

Objective
This study aimed to determine the perceived usefulness, competency, and associated factors in using DHIS2 data among district health managers (DHMs) in Tanzania.

Methods
This descriptive cross-sectional study used a quantitative approach, which involved using a self-administered web-based questionnaire. This study was conducted between April and September 2019. We included all core and co-opted members of the council or district health management teams (DHMTs) from all 186 districts in the country. Frequency and bivariate analyses were conducted, and the differences among categories were measured by using a chi-square test. P values of <.05 were considered significant.

Results
A total of 2667 (77.96%) of the expected 3421 DHMs responded, of which 2598 (97.41%) consented and completed the questionnaires. Overall, the DHMs were satisfied with DHIS2 (2074/2596, 79.83%) because of workload reduction (2123/2598, 81.72%), the ease of learning (1953/2598, 75.17%), and enhanced data use (2239/2598, 86.18%). Although only half of the managers had user accounts (1380/2598, 53.12%) and were trained on DHIS2 data analysis (1237/2598, 47.61%), most claimed to have average to advanced skills in data validation (1774/2598, 68.28%), data visualization (1563/2598, 60.16%), and DHIS2 data use (1321/2598, 50.85%). The biggest challenges facing DHMs included the use of a paper-based system as the primary data source (1890/2598, 72.75%) and slow internet speed (1552/2598, 59.74%). Core members were more confident in using DHIS2 compared with other members (P=.004), whereas program coordinators were found to receive more training on data analysis and use (P=.001) and were more confident in using DHIS2 data compared with other DHMT members (P=.001).

Conclusions
This study showed that DHMs have appreciable competencies in using the DHIS2 and its data. However, their skill levels have not been commensurate with the duration of DHIS2 use. This study recommends improvements in the access to and use of DHIS2 data. More training on data use is required and should involve using cost-effective approaches to include both the core and noncore members of the DHMTs. Moreover, enhancing the culture and capacity of data use will ensure the better management and accountability of health system performance.
