RESUMO

PURPOSE OF REVIEW: Radical cystectomy is a complex procedure that encompasses surgery involving the urinary, gastrointestinal tracts and the retroperitoneum, with significant morbidity. Robot-assisted radical cystectomy (RARC) has been introduced to improve perioperative outcomes. RECENT FINDINGS: It has been shown to provide equivalent oncologic outcomes to open radical cystectomy while providing some benefits in terms of perioperative outcomes. A complete intracorporeal approach utilizing intracorporeal urinary diversion may potentially offer additional benefits. SUMMARY: Herein, we describe our technique for RARC and intracorporeal urinary diversion, as well as a review of oncologic and perioperative outcomes.

RESUMO

There is no much published data on the mothers' false beliefs about signs and symptoms associated with teething in Sudan. Aim: This cross-sectional hospital-based study was conducted to assess mothers` knowledge about infant teething process and to evaluate mothers' practices used to alleviate teething disturbances in Gadarif city, eastern Sudan. Methods: Questionnaires were used to collect data. Multivariate logistics regression models were performed and adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated. Results/Conclusion: Of a total of 384 participating mothers, 126 (32.8%) had good knowledge about infant teething. The mothers' knowledge was associated with a higher number of children in the family (adjusted odds ratio [AOR] = 1.14) and with having a job (AOR = 2.22). Mothers residing in rural areas (AOR = 0.40) and mothers with lower than secondary education (AOR = 0.43) were less likely to have good knowledge about teething. Diarrhea (88.5%), fever (86.5%), an urge to bite (76.6%), and poor appetite (71.9%) were the signs and symptoms most attributed to teething by mothers. Only the mother's knowledge about teething was associated with reporting fever as a sign. A considerable number (317; 82.6%) of mothers reported performing "Dokhan" (acacia wood smoke), 313 (81.5%) preferred to administer paracetamol or other systemic analgesics, 262 (68.2%) agreed that a child with tooth eruption should be taken to a hospital or health center, and 216 (56.3%) believed that antibiotics relieved symptoms related to teething

RESUMO

Accurate prediction of inlet chemical oxygen demand (COD) is vital for better planning and management of wastewater treatment plants. The COD values at the inlet follow a complex nonstationary pattern, making its prediction challenging. This study compared the performance of several novel machine learning models developed through hybridizing kernel-based extreme learning machines (KELMs) with intelligent optimization algorithms for the reliable prediction of real-time COD values. The combined time-series learning method and consumer behaviours, estimated from water-use data (hour/day), were used as the supplementary inputs of the hybrid KELM models. Comparison of model performances for different input combinations revealed the best performance using up to 2-day lag values of COD with the other wastewater properties. The results also showed the best performance of the KELM-salp swarm algorithm (SSA) model among all the hybrid models with a minimum root mean square error of 0.058 and mean absolute error of 0.044.

RESUMO

Deltamethrin is a widely used insecticide that kills a wide variety of insects and ticks. Deltamethrin resistance develops as a result of intensive, repeated use, as well as increased environmental contamination and a negative impact on public health. Its negative impact on aquatic ecology and human health necessitated the development of a new technique for environmental remediation and wastewater treatment, such as the use of nanotechnology. The co-precipitation method was used to create Zn-Fe/LDH, Zn-AL-GA/LDH, and Fe-oxide nanoparticles (NPs), which were then characterized using XRD, FT-IR, FE-SEM, and HR-TEM. The kinetic study of adsorption test revealed that these NPs were effective at removing deltamethrin from wastewater. The larval packet test, which involved applying freshly adsorbed deltamethrin nanocomposites (48 hours after adsorption), and the comet assay test were used to confirm that deltamethrin had lost its acaricidal efficacy. The kinetics of the deltamethrin adsorption process was investigated using several kinetic models at pH 7, initial concentration of deltamethrin 40 ppm and temperature 25°C. Within the first 60 min, the results indicated efficient adsorption performance in deltamethrin removal, the maximum adsorption capacity was 27.56 mg/L, 17.60 mg/L, and 3.06 mg/L with the Zn-Al LDH/GA, Zn-Fe LDH, and Fe Oxide, respectively. On tick larvae, the results of the freshly adsorbed DNC bioassay revealed larval mortality. This suggests that deltamethrin's acaricidal activity is still active. However, applying DNCs to tick larvae 48 hours after adsorption had no lethal effect, indicating that deltamethrin had lost its acaricidal activity. The latter result corroborated the results of the adsorption test's kinetic study. Furthermore, the comet assay revealed that commercial deltamethrin caused 28.51% DNA damage in tick cells, which was significantly higher than any DNC. In conclusion, the NPs used play an important role in deltamethrin decontamination in water, resulting in reduced public health risk. As a result, these NPs could be used as a method of environmental remediation.

RESUMO

Background: Healthcare workers (HCWs) are still at higher risk of acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections than the general population. Identifying risk factors associated with severe SARS-CoV-2 infections is of paramount importance to protect HCWs and the non-infected patients attending different healthcare facilities. Purpose: To recognize the predictors for severity of SARS-CoV2 infection among HCWs working in either COVID-19 or non-COVID-19 healthcare settings. Also, to assess compliance of HCW to standard precautions of infection control and explore the possible risk factors for SARS-CoV-2 infection among HCWs. Methods: A cross-sectional study was conducted among HCWs with suspected or confirmed SARS-CoV-2 infection, from different Egyptian governorates. They were asked to fill in a web-based self-reporting questionnaire. The questionnaire assessed the demographic and socio-economic characteristics of participants, compliance of HCWs to standard precautions of infection control and COVID-19 presentation. Results: Our study enrolled 204 HCWs (52.3% physicians). Infection of SARS-CoV-2 was confirmed in 61.3% by RT- PCR; 35.8% were admitted to hospital, and of these, 3.9% were admitted to the intensive care unit. While 30.4% had mild disease, 48.5% had moderate disease, 17.2% had severe disease and 3.9% had critical disease. Regression analysis for variables predicting COVID-19 severity among study healthcare workers showed that associated chronic diseases and management at home were the main independent variables predicting severity of their SARS-COV-2 infection, while the variables age, sex, residence, occupation or drug history of immunosuppressives had no role in severity prediction. Conclusion: Associated chronic diseases and management at home were the main independent variables predicting severity of SARS-COV-2 infection among HCWs. So, HCWs with chronic diseases should not work in COVID-19 designated hospitals, and there should be a screening strategy for their infection with SARS-COV-2. HCWs must not be negligent in adhering to strict precautions of infection control. HCWs infected with SARS-COV-2 must be managed in hospital not at home.

RESUMO

Heavy metal contamination is a severe problem with serious ecological and human health effects due to its toxic effect and tendency to accumulate throughout the food chain. Batch experiments were conducted to investigate the simultaneous removal of arsenic, iron and manganese ions from aqueous solutions using Nanocarbon hybrid (NCH). Nanocarbon hybrid (NCH) of carbon xerogel decorated with 1wt% multi-walled carbon nanotubes was prepared by carbonization at 850 °C for 2 h. The TEM, SEM, EDX, FTIR, and N2 adsorption-desorption measurements were used to characterize the prepared NCH. NCH is enriched with surface oxygen functional groups and micropores as well as it have total surface area of 162 m2/g and total pore volume of 0.129 cm3/g. The adsorption of metal ions onto NCH, which confirmed by EDX, happened quickly, with 30%, 97%, and 41% of As, Fe, and Mn adsorbed in less than 10 min, however the equilibrium time was achieved in less than 30 min. The maximum adsorption capacities for As, Fe, and Mn ions onto NCH were 20, 48, and 21 mg/g, respectively. The experimental adsorption results of the three metal ions showed linearly fitting with Freundlich isotherms. In addition, the computed adsorption energies for Fe, Mn, and As ions were 4.08, 1.95, and 2.42 kJ/mol, indicating physical adsorption. NCH are easily regenerated and reusable sorbent owing to the adsorption-desorption studies. Conclusively, NCH is promising material for removing mixture of metal ions from aqueous media.

RESUMO

Programmed cell death (PCD) is a fundamental genetically controlled process in most organisms. PCD is responsible for the selective elimination of damaged or unwanted cells and organs to maintain cellular homeostasis during the organ's development under normal conditions as well as during defense or adaptation to stressful conditions. PCD pathways have been extensively studied in animals. In plants, studies focusing on understanding the pathways of PCD have advanced significantly. However, the knowledge about the molecular basis of PCD is still very limited. Some PCD pathways that have been discovered in animals are not present in plants or found with a similar form. PCD in plants is developmentally controlled (by endogenous factors) to function in organ development and differentiations as well as environmentally induced (by exogenous stimuli) to help the plant in surviving under stress conditions. Here, we present a review of the role of PCD in plant development and explore different examples of stress-induced PCD as well as highlight the main differences between the plant and animal PCD.

RESUMO

Although several studies have reported a toxic effect of diesel exhaust particles (DEP) exposure on the kidney tissues, the involvement of autophagy/NF-kB signaling as encountered mechanisms and the protective effects of a natural flavonoid, quercetin on DEP remains unclear. Thirty-two albino rats were divided as control, quercetin-treated (60 mg/kg, oral), DEP-exposed (0.5 mg/kg, intra-tracheal), and quercetin/DEP-exposed groups. Specimens of the renal cortex were subjected to histo-biochemical study and immunohistochemical analysis using anti-NF-kB, and anti-LC3ß antibodies followed by morphometric and statistical analyses. The expression level of autophagy genes was quantitatively evaluated using RT-PCR, as well. The DEP-exposed rats showed an elevation in the renal tissue levels of MDA and a decrease in the catalase and superoxide dismutase (p < .05). Histologically, there were cytoplasmic vacuolar changes in the lining cells of the renal tubules, glomerular atrophy, and vascular congestion. In addition, renal inflammation was evident as confirmed by the increased NF-kB immunoexpression. Moreover, the gene expression of Becn1, ATG5, and LC3ß increased (p <. 0) due to DEP exposure. Conversely, quercetin pretreatment improved these renal histo-biochemical alterations (p < .05) and regulated autophagy/NF-kB pathways. Overall, the study proved the renal toxicity mediated by DEP exposure via precipitating renal inflammation, autophagy activation, and oxidative stress. Quercetin pretreatment could antagonize such machinery to protect the kidney against DEP.

RESUMO

A new glass system (50-x)P2O5-20B2O3-5Al2O3-25Na2O-xCoO was manufactured using a standard melt quenching procedure, where 1≤ x ≤ 12 mol%. The characteristics of boro-phosphate-glasses containing CoO have been studied. The effect of CoO on the radiation-protective properties of glasses was established. The density of the prepared glasses as a function of CoO increased. XRD was used to check the vitreous structure of samples. Fourier-transform infrared (FTIR) spectroscopy was used to study the structure of each sample. FTIR demonstrated that connections grew as CoO/P2O5 levels increased, and the FTIR spectra shifted to higher wavenumbers. The increment of CoO converts non-bridging oxygens associated with phosphate structural units into bridging oxygens. This process increases the concentration of BO4 structural units and creates new, strong and stable bonds B-O-P, i.e., there is polymerization of the boro-phosphate glass network. With an increase in the ratio of CoO/P2O5 in the produced samples, ultrasonic velocities and elastic moduli were observed to increase. The coefficients of linear and mass attenuation, the transmittance of photons in relation to the photon energy, the efficiency of radiation protection in relation to the photon energy, and the thickness of the absorber were modeled using these two methods (experimental and theoretical). From the obtained values, it can be concluded that the 12Co sample containing 12 mol% will play the most influential role in radiation protection. An increase in the content of cobalt-I oxide led to a significant increase in the linear and mass attenuation coefficient values, which directly contributes to the development of the radiation-protective properties of glass.

RESUMO

This study aimed to develop propolis and tea tree oil nanoemulsion loaded with clindamycin hydrochloride to heal wound effectively. Nanoemulsion formulae were prepared and characterized by droplet size analysis, zeta potential, viscosity, ex-vivo permeation, and skin deposition. The optimal formula was evaluated in terms of morphology, cytotoxicity, and in-vitro wound healing assay. Also, the efficacy of the optimal formula was evaluated by in-vivo wound healing and histopathological studies. The optimal formula (F3) was composed of 9% tea tree oil and 0.4% propolis extracts with mean droplet size 19.42 ± 1.7 nm, zeta potential value -24.5 ± 0.2 mV, and viscosity 69.4 ± 1.8 mP. Furthermore, the optimal formula showed the highest skin deposition value 550.00 ± 4.9 µg/cm2 compared to other formulae. The TEM micrograph of the optimal formula showed that the nanoemulsion droplet has an almost spherical shape. Also, the optimal formula did not show noticeable toxicity to the human skin fibroblast cells. The in-vitro and in-vivo wound healing assay showed unexpected results that the un-loaded drug nanoemulsion formula had a comparable wound healing efficacy to the drug-loaded nanoemulsion formula. These results were confirmed with histopathological studies. Our results showed that the propolis and tea tree oil nanoemulsion, whether loaded or unloaded with an antibiotic, is an efficient local therapy for wound healing.

RESUMO

UV-filters are widely used in cosmetics and personal care products to protect users' skin from redamage caused by ultraviolet (UV) radiation from the sun. Globally, an estimated 16,000 to 25,000 tonnes of products containing UV-filters were used in 2014 with modern consumption likely to be much higher. Beyond this use in cosmetics and personal care products, UV-filters are also widely used to provide UV-stability in industrial products such as paints and plastics. This review discusses the main routes by which UV-filters enter aquatic environments and summarises the conclusions of studies from the past 10 years that have investigated the effects of UV-filters on environmentally relevant species including corals, microalgae, fish, and marine mammals. Safety data regarding the potential impact of UV-filters on human health are also discussed. Finally, we explore the challenges surrounding UV-filter removal and research on more environmentally friendly alternatives to current UV-filters.

RESUMO

BACKGROUND AND OBJECTIVES: To examine abusive head trauma (AHT) trends using data obtained from hospital-based child protection centers (CPCs) and the distribution of age in months among young children in Saudi Arabia. METHODS: A retrospective study was conducted that includes data obtained from 58 hospital-based CPCs in all 13 regions of Saudi Arabia registered in the National Family Safety Registry from 2010 to 2020. AHT cases (n=106) were identified for inclusion in the registry by a daily review of the emergency department logbooks. RESULTS: Over the 11-year period, there was a sharp increase in the number of cases, specifically after 2014, from seven cases per year in 2010 to 16 cases in 2020. AHT affects predominantly children aged 0-12 months (72.6%), followed by 13-24 months (17.9%), 25-36 months (3.8%), 37-48 months (3.8%), and 49-60 months (1.9%). Victims were characterized by a predominance of crying infants (23.6%), past history of abuse (13.2%), a child's chronic disease and disability (7.6%), and prematurity (2.8%). CONCLUSION: Different training and educational programs need to be performed to raise awareness of AHT. Enacting the pediatrician's mandatory reporting law will improve the rate of reporting cases.

RESUMO

The focus of this study was to determine the depth-wise variability of physicochemical properties (i.e., pH, TOC, TN, and EC), and heavy metals (i.e., Pb, Cu, Zn, As, and Cr) concentration, and the associated biological and ecological risks of the mangrove sediment. The accumulation of metal contents and the phytoremediation and phytoextraction were also investigated in a mangrove species, Acanthus ilicifolius. The mangrove sediment consists of a higher proportion of sand fraction (56.6-74.7%) followed by clay (10-28%) and silt (10.1-15. 7%) fractions. The concentrations (mg/kg) of Pb, Cu, Zn, As, and Cr were ranged from 22.05-34.3, 8.58-22.77, 85.07-114, 5.56-12.91, and 0.98-5.12 in all the sediment layers. The hierarchy of the mean metal concentration in sediment was Zn (102 mg/kg) > Pb (25.6 mg/kg) > Cu (14.8 mg/kg) > As (8.79 mg/kg) > Cr (2.74 mg/kg) respectively. The examined metal concentrations were below the respective average shale values (ASVs). The degree of environmental, ecological, and biological risks was minimal according to various pollution indices like geoaccumulation index (Igeo), contamination factor (CF), and pollution load index (PLI). According to sediment quality guidelines (SQGs), the adverse biological risk effect was not likely to occur. The result of the potential ecological risk index (PERI) demonstrated that the study area was in the low-risk condition as the corresponded RI value < 100. A combined influence of geogenic and anthropogenic factors was identified as the metal sources by multivariate analysis. The study found that the accumulation rate of the metal contents was higher in leaves than that of roots. The mean descending metal concentration values were Zn (107) > Pb (28. 7) > Cu (16.9) > As (11.2) > Cr (4.99) in leaves and Zn (104.32) > Pb (27.02) > Cu (15.29) > As (10.39) > Cr (3.80) in roots. The translocation and bioaccumulation factors of heavy metals suggested that the mangrove plant species, A. ilicifolius can be used for phytoremediation and phytoextraction since the bio-concentration factor and translocation factor > 1. The studied species exhibited the metal tolerance associated with two following strategies, metal exclusion, and metal accumulation. However, excess metal tolerance can impact the surrounding marine environment.

RESUMO

We present the case of a 69-year-old man patient who was brought with a history of gait disturbances, memory impairment, and urinary incontinence with gradual worsening over the past six months. The patient underwent magnetic resonance imaging of the brain which demonstrated enlarged ventricles, widening of the Sylvian fissure, and narrow sulci at the vertex. Subsequently, the patient underwent a lumbar puncture which revealed a normal opening pressure with normal cerebrospinal fluid analysis. The diagnosis of normal pressure hydrocephalus was established. The patient underwent a ventriculoperitoneal shunt for the management of his symptoms. Three years after the placement of the shunt, the patient was brought to the emergency department with an expanding right-sided subcutaneous abdominal mass. A computed tomography scan of the abdomen showed the subcutaneous mass superficial to the right rectus muscle and was containing the coiled distal end of the shunt. Such findings were consistent with a subcutaneous cerebrospinal fluid pseudocyst. The mass was aspirated and the fluid analysis was in keeping with the cerebrospinal fluid characteristics. The fluid culture revealed no bacterial growth. The ventriculoperitoneal shunt was replaced with a minimally invasive technique.

RESUMO

In this work, Deep Bidirectional Recurrent Neural Networks (BRNNs) models were implemented based on both Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) cells in order to distinguish between genome sequence of SARS-CoV-2 and other Corona Virus strains such as SARS-CoV and MERS-CoV, Common Cold and other Acute Respiratory Infection (ARI) viruses. An investigation of the hyper-parameters including the optimizer type and the number of unit cells, was also performed to attain the best performance of the BRNN models. Results showed that the GRU BRNNs model was able to discriminate between SARS-CoV-2 and other classes of viruses with a higher overall classification accuracy of 96.8% as compared to that of the LSTM BRNNs model having a 95.8% overall classification accuracy. The best hyper-parameters producing the highest performance for both models was obtained when applying the SGD optimizer and an optimum number of unit cells of 80 in both models. This study proved that the proposed GRU BRNN model has a better classification ability for SARS-CoV-2 thus providing an efficient tool to help in containing the disease and achieving better clinical decisions with high precision.

RESUMO

Purpose: The purpose of this study is to evaluate the short-term results of lateral closing wedge osteotomy with medial hemiplateau elevation for the management of severe infantile Blount's disease. Materials and methods: In this prospective study, 11 cases of severe Blount's disease (Langenskiold stages five and six) were managed in the period between January 2017 and January 2020. Double osteotomy technique was applied, namely a metaphyseal closing wedge and a medial hemiplateau elevation, through a single midline incision. Fixation was achieved by a medial anatomical locked plate. Patients were evaluated clinically according to a modified version of paediatric outcomes data collection Instrument (PODCI) and radiologically by measuring the angle between the tibial and the femoral shaft, the mechanical axis deviation (MAD) and the angle of the medial tibial plateau (MTP) depression. Results: The average follow-up period was 2 years. Healing of the osteotomies was achieved in all cases after the index operation within an average of 3 months. Based on our modification of the PODCI score, five cases had an excellent outcome, five were good, and one case ended with a fair outcome. No major complications were encountered in this study. Conclusion: The management of severe Blount's disease by acute correction using the aforementioned technique has been proven to achieve acceptable clinical and radiological outcomes without significant complications. Level of evidence: Level IV case series study. How to cite this article: Nada AA, Hammad ME, Eltanahy AF, et al.

RESUMO

Fatty acid binding protein 4 (FABP4) was crucial to fatty acid uptake and intracellular transport. However, the mechanisms regulating yak (Bos grunniens) FABP4 transcription were not determined. In the current study, predominant expression levels of yak FABP4 were identified in subcutaneous fat and longissimus dorsi muscles by quantitative real-time polymerase chain reactions (qPCR). The CCAAT/enhancer binding protein alpha (CEBPα) and myocyte enhancer factor 2A (MEF2A), as transcriptional activator or repressor in the promoter region of FABP4, were confirmed by both site-directed mutagenesis experiment and chromatin immunoprecipitation assay. Additionally, molecular mechanisms of CEBPɑ regulation were analyzed to explore the transcriptional regulatory property of FABP4, which indicated that transcriptional activity of CEBPɑ depended on CCAAT/ enhancer binding protein beta (CEBPß) transcription factor. Our results demonstrated that CEBPß binding directly to the promoter region drove CEBPɑ transcription, improving yak FABP4 transcriptional activity in adipocytes. This mechanism expanded the information on the transcriptional regulatory network of adipogenesis.

RESUMO

Background: This study was aiming to assess factors influencing the contribution of primary healthcare physicians concerning prevention of type 2 diabetes in the Jazan region, south of Saudi Arabia. Materials and Methods: A cross-sectional study was conducted to assess physicians' knowledge about evidence-based guidelines concerning diabetes prevention, their attitude towards lifestyle interventions and their practice concerning screening and provision of lifestyle interventions in their clinics. Interviews were conducted to complete a semi-structured questionnaire. Data analysis involved reviewing open-ended responses of physicians followed by quantitative analysis to assess level of knowledge, attitudes, and practice adherence. Results: A total of 234 physicians from 127 primary healthcare centres (PHCs) in the region were recruited. Knowledge of evidence-based clinical indicators for the prevention of diabetes was limited (mean level of knowledge 3.14/8 [SD: 1.2)]. Recruited physicians did have a positive overall attitude to the influence of lifestyle/behavioural therapy on the prevention of type 2 diabetes. The physicians narrated a variety of factors that might influence the effectiveness of this approach, which were related to the community, the patients and the physicians themselves. Only the association between gender of physicians and their levels of knowledge was statistically significant where odds of greater knowledge were higher among female physicians in comparison to males (odds ratio : 1.8, P value = 0.025). Conclusion: Most of the physicians in our sample were misinformed about the components of lifestyle/behavioural interventions for diabetes prevention, which mandates designing and implementing lifestyle medicine programmes for the PHC physicians in Jazan region.

RESUMO

OBJECTIVES: This study aimed to evaluate the extent to which online communication can enhance patients' knowledge of orthodontic topics, as well as compare the effectiveness of images, video, and text messages as tools for delivering orthodontic information. MATERIALS AND METHODS: Two WhatsApp groups were created comprising 30 males and 33 females. The Google form template was used to formulate a 25-item questionnaire containing information related to orthodontic topics. At the beginning of the first stage, a link to the questionnaire was sent to the groups and their answers were given scores, which were referred to as (T1). During the second stage, a piece of daily information relevant to the field of orthodontics was sent to the groups over a 14-day period. On Day 15, the link to the previous questionnaire was sent again and the participants were asked to complete it for a second time. These answers were corrected, given scores, and labeled as (T2). Scores from the first and second stages were compared. RESULTS: There was a significant increase in the average total score from the first questionnaire (T1 = 15.3) to the second questionnaire (T2 = 17.9). All types of media formats were greatly effective in improving the patients' knowledge. Images proved to be the best tool for delivering information and were considerably more effective than video and text messages. CONCLUSION: This study indicates that WhatsApp as an online communication tool could be used to effectively enhance the knowledge of orthodontic patients. Images are the best method for delivering information to orthodontic patients.
