Diante da necessidade de propor uma qualificação para transformação e aprimoramento dos Agentes Comunitários de Saúde (ACS), considera-se de fundamental importância a identificação do conhecimento desses atores, que representam um elo entre o serviço e a comunidade, em especial, na atenção à Tuberculose (TB). Assim, o presente estudo teve como objetivo desenvolver uma intervenção educativa sobre TB para ACS, de duas Unidades de Saúde da Família, no município de Porto Velho-RO. Trata-se de um estudo descritivo, com abordagem quantitativa. Os dados foram coletados entre março e abril de 2017, por meio de um questionário estruturado, e a análise através de estatística descritiva. A intervenção foi delineada, a partir das lacunas do conhecimento identificadas e realizada em encontros de quatro horas cada, com os mesmos conteúdos e metodologia. Verificou-se que os ACS possuíam um conhecimento restrito sobre as características gerais da TB, diagnóstico, tratamento, medidas de prevenção e vigilância dos casos. Tais achados permitem refletir sobre a importância dos processos formativos e de qualificações constantes que possibilitem o diálogo com os profissionais sobre o cenário em que suas atribuições são desempenhadas e as dificuldades vivenciadas, visando um planejamento coerente e participativo com os atores envolvidos.

Abstract
Downhole RF heating continues to be the interest of the petroleum industry because of its advantages over conventional forms of heating. Previous results have shown that without a low-loss dielectric zone (LLZ) around the downhole RF emitter, none of the available linear dipole antennas can work efficiently, and most of the energy is absorbed preferentially in a few meter radius around the radiating well and will not penetrate substantially into the reservoir. To circumvent this problem, low-dielectric materials were proposed, which are composed of a solid mixed with an appropriate binder. These materials were selected to have low dielectric properties so that the RF absorption is minimized, and at the same time, low porosity to prevent water invasion during the RF heating operation. Four solids, Ottawa sand, solvent deasphalted tar, Poly(p-phenylene sulfide) (PPS) and Polyether ether ketone (PEEK) and four binders (polydicyclo pentadiene (DCPD) and phenol-formaldehyde resins (Novolac), a C-Class cement slurry, and a foamed cement) were evaluated by measuring their dielectric properties (dielectric constant and loss tangent) in the frequency range 1 - 2000 kHz and temperatures between 25–200°C. All four solids have low RF absorption as well as low porosity (&lt;1%), and those values did not change significantly with temperature. Also, smaller dielectric properties were found for DCPD and Novolac than those found for the cement materials, and the DCPD binder has a dielectric constant almost half and a loss tangent one order of magnitude lower than those measured for the Novolac resin. Three different designs for the construction of LLZ were considered, which included underreaming the oil well, squeezing a solid-containing binder downhole, and creating a casing-less completion. Numerical simulations show that the use of a low-loss zone around the central emitter leads to a very much improved energy and temperature distribution, and higher penetrations (~12 m) than the case without it.

Abstract
Solvent Assisted-Steam Assisted Gravity Drainage (SA-SAGD) has been studied as a more efficient process for extracting bitumen from oil sands than the SAGD process. In the SA-SAGD process, solvent is injected with steam to decrease the viscosity of bitumen by dissolution of the condensed solvent.
The dissolution of solvent causes a composition change of bitumen, which can lead to asphaltene precipitation. The effects of the asphaltene precipitation have been studied as part of a solvent-based recovery process such as Vapor Extraction (VAPEX). One of the advantages of the asphaltene precipitation is in-situ upgrading of the bitumen, whereas the disadvantage is that it causes a formation damage.
To evaluate the effect of the asphaltene precipitation in the SA-SAGD process, it is essential to investigate the asphaltene precipitation under the conditions expected in the SA-SAGD process. However, it takes a lot of time to obtain sufficient data with a conventional method to quantify asphaltene precipitation under high-pressure/high- temperature (HP/HT) conditions.
Therefore, the aim of this study is to develop an experimental procedure to evaluate the asphaltene precipitation with pressure/volume/temperature (PVT) apparatus in a reasonable time. The complex phenomenon at the edge of the chamber in the SA-SAGD process was simplified to a model of repetitions of mixing and drainage processes, and the experiment was configured in this manner. Solvent was added to a pre-diluted bitumen sample in a PVT cell. The supernatant liquid was sampled to analyze the asphaltene weight fraction remaining in the liquid phase and evaluate the asphaltene precipitation amount in the PVT cell. This process was repeated with increase in the solvent concentration. The asphaltene precipitation amount (APA) is calculated from the sample analysis data with recurrence relations under several assumptions.
This procedure enables a wide range of APAs to be obtained from a mixture of bitumen and solvent in a single experiment, which enables sensitivity analysis under various conditions. In this research, the experiment was conducted under two different temperature conditions of 120°C and 150°C and the pressure was fixed at 3.5 MPa. The APA curves obtained from both experiments had almost the similar trend.
Another important observation is that even the multi-component solvent (as used at the operation site) can still induce asphaltene precipitation under the HP/HT conditions expected in the SA-SAGD process.

Abstract
Background: Neither inactivated vaccine nor attenuated vaccine can effectively prevent and control the infection and spread of porcine reproductive and respiratory syndrome virus (PRRSV). Therefore, it is necessary to broaden new horizons and to conceive effective preventive strategies. Tea polyphenols (TPP) are polyphenol in tea. The main components of TPP are catechins and their derivatives. TPP has many physiological activities and has certain antiviral and antifungal effects. But whether TPP owns anti-PRRSV activity remains unclear. Results: We found that TPP effectively inhibited PRRSV replication in Marc-145 cells by suppressing viral attachment and internalization. TPP exhibited a potent anti-PRRSV effect regardless of its pre-treatment or post-treatment. In addition, we demonstrated that TPP restrained PRRSV-induced p65 entry into the nucleus to suppress the activation of the NF-κB signaling pathway, which ultimately leads to the inhibition of the expression of inflammatory cytokines. Furthermore, TPP limited the synthesis of viral non-structural protein 2 (nsp2), the core component of viral replication transcription complexes, which may contribute to the inhibition of viral RNA replication. Conclusions: TPP has the potential to develop into an effective antiviral agent for PRRSV prevention and control in the future.

Abstract
Microbial desalination cell (MDC) built on surface modification has been studied for seawater desalination. Herein, the bio-catalytic surface modification for maintenance the long-term MDC performance during desalination process has been developed. The goal of this study is to provide and develop a seawater desalination system without requiring energy support by applying a modification of anode as an electron acceptor, and the different potential charges that occur between anode and cathode can play as driving force for electrodialysis of seawater desalination. Yeast has been applied as biocatalyst, meanwhile neutral red has been chosen as redox mediator to facilitate the electron transport from bioactivity of cells. Several types of surface modification have been conducted, i.e. biocatalyst-mediator immobilization and electropolymerization of NR at the surface of the anode. The optimization of each device has been characterized by cyclic voltammetry, chronoamperometry, and observed in Microbial fuel cell (MFC) prior functioned in MDC. The concentrations of salt ion migration have been determined by Ion Exchange Chromatography. MFC results reported that the best configuration of surface modification was obtained from CF/PNR then applied in MDC. CF/PNR delivered the highly significant performance by having the maximum value of all tested parameters, i.e 42.2% of current efficiency; 27.11% of bio-devices efficiency; 92.5 mA m-2 of current density and also 61% of NaCl transport. The profiles of surface devices have been detected by Scanning electron microscope (SEM) and Energy Dispersive X-ray spectroscopy (EDX). A several spherical shapes around 4 nm within alginate layer have been detected from SEM images and it was confirmed as yeast, meanwhile 5.04% of N has been found from EDX spectrum and was indicated from PNR. The results show that surface modification could be a promising method for bioelectricity generation which simultaneously produces electricity and seawater desalination and provides a green chemistry technology.

Published: September 2020

Abstract
Background To assess the resolution of clinical symptoms and radiographic changes in root length and apical diameter in immature permanent teeth with irreversible pulpitis or apical periodontitis with vital inflamed pulp therapy (VIPT).Methods The faculty members at the Ninth People’s Hospital pediatric dentistry department were invited to submit consecutive VIPT cases treated by them, irrespective of outcome, between 2014 and 2016. Clinical success rate, radiographic changes in periapical radiolucency, and apical closure were analyzed, and radiographic changes in the apical diameter and root length were quantified.Results Thirteen of 14 submitted cases of irreversible pulpitis in immature teeth met the inclusion criteria. The follow-up period ranged from 17 to 37 (average, 26.5 ± 7) months. All 13 treated teeth (100%) survived and 12 (92.3%) met the clinical criteria for success throughout the follow-up period, with 92.3% of cases (12 of 13) showing a significant periapical radiolucency decrease and 84.6% (11 of 13) showing complete apical closure at the last visit. The change in apical diameter and root length were obvious. Conclusions Vital inflamed pulp therapy approaches might be of particular value in restoring root development and apical closure and can be an option in treating immature teeth with irreversible pulpitis, even apical periodontitis.

Abstract
Background: Daily management to shield chronic dialysis patients from SARS-CoV-2 contamination makes patient care cumbersome. There are no screening methods to date and a molecular biology platform is essential to perform RT-PCR for SARS-CoV-2; however, accessibility remains poor. Our goal was to assess whether the tools routinely used to monitor our hemodialysis patients could represent reliable and quickly accessible diagnostic indicators to improve the management of our hemodialysis patients in this pandemic environment.Methods: In this prospective observational diagnostic study, we recruited patients from La Conception hospital. Patients were eligible for inclusion if suspected of SARS-CoV-2 infection when arriving at our center for a dialysis session between March 12th and April 24th 2020. They were included if both RT-PCR result for SARS-CoV-2 and cell blood count on the day that infection was suspected were available. We calculated the area under the curve (AUC) of the receiver operating characteristic curve.Results: 37 patients were included in the final analysis, of which 16 (43.2%) were COVID-19 positive. For the day of suspected COVID-19, total leukocytes were significantly lower in the COVID-19 positive group (4.1 vs 7.4 G/L, p=0.0072) and were characterized by lower neutrophils (2.7 vs 5.1 G/L, p=0.021) and eosinophils (0.01 vs 0.15 G/L, p=0.0003). Eosinophil count below 0.045 G/L identified SARS-CoV-2 infection with AUC of 0.9 [95% CI 0.81-1] (p<0.0001), sensitivity of 82%, specificity of 86%, a positive predictive value of 82%, a negative predictive value of 86% and a likelihood ratio of 6.04.Conclusions :Eosinophil count enables rapid routine screening of chronic hemodialysis patients suspected of being COVID-19 within a range of low or high probability.

Abstract
Background: Bovine Tuberculosis is globally the paramount cause of death from single pathogen in cattle and other species. Rapid and explicit identification of mycobacteria is essential for the control of bovine tuberculosis. We performed a fluorescence Peptide nucleic acid fluorescence in situ hybridization (PNA-FISH) procedure for specific detection of Mycobacterium bovis and Mycobacterium avium in bovine was optimized on cytological smears and tissue sections of bovines suspected for bovine tuberculosis.Results: PNA-FISH was performed on lung and lymph node tissues impression smears. The probes were standardized for standard bovine mycobacterial cultures at 50% formamide concentration for M.bovis and 30% formamide concentration for M.avium. All the cytological smears were positive from M.bovis probe (MTBCcy3) which was standardized at hybridization conditions of (55oC and 40% formamide) concentrations. Results revealed 4 out of 25 were positive in tissue sections with a bright red fluorescence with cy3 filter (MTBC probe). No results were seen with (MAVTAMRA) probe for M.avium which was standardized at hybridization conditions of (55oC and 30% formamide) respectively. No fluorescence was seen in control tissue sections .In addition, results were compared to other commonly used detection methods like IHC and PCR by targeting esxA gene. None of the sample was found positive for M. avium.Conclusion: PNA-FISH can be used in cytological impression smears and tissue sections. It is less time consuming in diagnosis of bTB in post mortem cases than PCR.

Published: September 2020

Abstract
Background: Dental caries is the most common chronic oral condition affecting millions of people worldwide. There are several predictors of dental caries that include amongst others water source, fluoride use, smoking status, alcohol use, employment status, level of education, diet and socioeconomic status. Aim: The aim of this study was to determine the risk factors and or predictors associated with dental caries among adults attending dental clinics at public health facilities in eThekwini and uMgungundlovu districts in the KwaZulu-Natal (KZN) province of South AfricaSetting: The study took place at thirteen dental public health clinics in eThekwini and six from uMgungundlovu districts in KZN province, South AfricaMethods: An observational cross-sectional study was conducted over a 5-month period from November 2018 to the end of March 2019 with a sample of 4716 patients of all adults 18 years and above age groups. A clinical examination as well as a close-ended questionnaire on the diagnosis, basic demographics data, socioeconomic status (SES), as well as lifestyle-related questions such as smoking, alcohol use and dietary choices, was administered to all consenting participants. Bivariate analysis and multivariate analysis using logistical regression were used to measure the association.Results: Females participants OR 1.4 (95% CI 1.2-1.6) p < 0.001**, patients consuming an unhealthy diet OR1.2 (95% CI 1.2-1.6) p < 0.001** were more likely to develop dental caries. Patients Achieving more than secondary level education were OR 0.8 (95% CI 0.7-0.9) p = 0.02* less likely to develop dental caries. Despite showing a slightly increased odds ratio OR 1.25 (95% CI 0.93-1.67) p = 0.14, lack of access to water was not a statistically significant contributor to dental caries.Conclusion: This study showed that female sex, consumption of an unhealthy diet and lower than a secondary level of education were the predictors of dental caries. It is hoped that these findings will contribute in influencing dental public health policy planning to ensure that planning for dental services takes a more comprehensive approach that includes health promotion, primary prevention, secondary prevention and tertiary prevention at appropriate levels of the health system.
HDL cholesterol efflux capacity and concentration in patients with rheumatoid arthritis: a systematic review and meta-analysis

Published: September 2020

Abstract
Background: Poor cholesterol efflux capacity (CEC) has been proposed to be an independent risk factor for cardiovascular diseases. However, the current evidences in the literature are inconsistent. This meta-analysis aimed to identify whether CEC is impaired or altered by drug therapy in individuals with rheumatoid arthritis (RA).Methods: The PubMed, Embase, and Cochrane library databases were searched to identify studies on CEC in RA patients. The searches were focused on studies in human subjects that were published before 10 June 2020, without language restrictions. The primary outcomes were CEC and the high-density lipoprotein cholesterol (HDL-C) and C-reactive protein levels (CRP) levels.Results: A total of 11 eligible articles, including 6 observational and 5 intervention studies, were retrieved. The pooled results showed that CEC is not significantly lower in RA patients than in healthy controls (SMD: -0.22, 95% CI: -0.65 to 0.20), whereas the plasma HDL-C level is not significantly (WMD: -3.98, 95% CI: -8.32 to 0.37, I² = 54%, P for heterogeneity = 0.050) but is significantly decreased in the RA patients with moderate body mass index (BMI) (WMD: -5.46, 95% CI: -9.40 to -1.52, I² = 37%, P for heterogeneity = 0.175). Furthermore, in the before-after studies, the CEC of RA patients (SMD: 0.20, 95% CI: 0.03 to 0.38) increased, but the plasma HDL-C level (WMD: 3.26, 95% CI: -0.17 to 6.69) remained at a similar level after anti-rheumatic treatment compared to the baseline. In addition, stratified analysis suggested that the Disease Activity Score for 28 joints could be a potential source of heterogeneity for CEC. The funnel plot was relatively symmetric and did not suggest the presence of publication bias.Conclusion：The current meta-analysis demonstrated that HDL-mediated CEC can be improved by the early control of inflammation and anti-rheumatic treatment in RA patients, which is independent of HDL-C levels. Future research is needed to determine whether therapeutic strategies to enhance CEC in RA patients have beneficial effects for preventing CVD.
