Integrating waste valorization and symbiotic microorganisms for sustainable bioremediation of metal(loid)-polluted soils.

Remediation strategies for metal(loid)-polluted soils vary among the wide range of approaches, including physical, chemical, and biological remediation, or combinations of these. In this study, we assessed the effectiveness of a set of soil remediation treatments based on the combined application of inorganic (marble sludge) and organic amendments (vermicompost, and dry olive residue [DOR] biotransformed by the saprobic fungi Coriolopsis rigida and Coprinellus radians) and inoculation with arbuscular mycorrhizal fungi (AMFs) (Rhizophagus irregularis and Rhizoglomus custos). The treatments were applied under greenhouse conditions to soil residually polluted by potentially toxic elements (PTEs) (Pb, As, Zn, Cu, Cd, and Sb), and wheat was grown in the amended soils to test the effectiveness of the treatments in reducing soil toxicity and improving soil conditions and plant performance. Therefore, we evaluated the influence of the treatments on the main soil properties and microbial activities, as well as on PTE availability and bioaccumulation in wheat plants. Overall, the results showed a positive influence of all treatments on the main soil properties. Treatments consisting of a combination of marble and organic amendments, especially biotransformed DOR amendments, showed the greatest effectiveness in improving the soil biological status, promoting plant growth and survival, and reducing PTE availability and plant uptake. Furthermore, AMF inoculation further enhanced the efficacy of DOR amendments by promoting the immobilization of PTEs in soil and stimulating the phytostabilization mechanisms induced by AMFs, thus playing an important bioprotective role in plants. Therefore, our results highlight that biotransformed DOR may represent an efficient product for use as a soil organic amendment when remediating metal(loid)-polluted soils, and that its application in combination with AMFs may represent a promising sustainable bioremediation strategy for recovering soil functions and reducing toxicity in polluted areas.

Autistic spectrum disorder children and adolescents' oral health characteristics - scoping review.

This study aimed to conduct a scoping review to know children and adolescents' main oral health concerns with Autism Spectrum Disorder (ASD) and thus identify any oral characteristic that stands out, aiming at preventive and interceptive clinical conduct. A search was performed in the three electronic databases and the gray literature; in September 2021. A total of 562 studies were identified, and after applying the eligibility criteria, 73 articles were included in the synthesis of this scoping review. The mean decayed, lost, and restored teeth index (DMFT/dfmt) ranged from 0 to 12.37; the mean DMFT index (permanent dentition) from 0.06 to 6.2; and the average dmft index (deciduous dentition) ranged from 0.29 to 9.91. The mean simplified oral hygiene index (OHIS) ranged from 0 to 3.4; gingival index (GI) from 0.29 to 2; and plaque index (PI) from 0.005 to 3.15. Plaque prevalence was 25.9% to 90%; dental calculus from 4.7% to 59.41%; gingivitis from 36.7% to 100%. Bruxism was 10.3% to 73%, and dental trauma was 4.7% to 100%. This disparity in the results shows the heterogeneity of this population, with different degrees of socio-behavioral impairment, which can directly influence oral hygiene and the consequent accumulation of biofilm.

Oral Health and Behavioral Management of Children with Autistic Spectrum Disorder: A 30-year Retrospective Study.

PURPOSE: This article aims to determine the oral health status, the dental treatment, the behavioral management techniques, and the follow-up of pediatric autistic spectrum disorder (ASD) patients treated at the Clinic for Pediatric Patients with Disabilities (CPPD) at a public university in Brazil. METHODS: The medical records of all the patients seen between 1990 and 2020 were evaluated. Data were collected on the autistic patients' medical and dental conditions, treatments, behavior during dental visits, behavioral management techniques used, and the entire follow-up period at the clinic. The Student's t-test and chi-square tests were used to perform the statistical analysis (α = 0.05%). RESULTS: Sixty-six records of ASD children were analyzed from a total of 656 dental records. The majority were male (80.3%). The mean age was 7.39 ± 2.75 years. All the children had a cognitive deficit, and 62.5% used medication. Most of the children arrived with caries lesions (56.1%), and the mean number of decayed, missed and filled teeth in both the deciduous (dmft-d) and permanent dentition (DMFT) was 2.45 ± 3.13 and 0.87 ± 1.51, respectively. The restorative technique was the most commonly used procedure (54.5%), and protective stabilization was the most frequently used behavioral management technique (18.2%). Of the children who sought treatment, 86.4% were discharged, and 15.2% abandoned the procedure. The majority (those discharged) continued to undergo regular follow-up at the clinic (86%), and the incidence of new caries lesions observed was 33.33% Conclusions: Although our ASD patients had a high frequency of caries and dental treatment needs, we observed good adherence to the treatment, with a low dropout rate, and high discharge rate.

Drug-resistant tuberculosis in Colombia, 2013-2018: Case-control study / Tuberculosis multirresistente en Colombia, 2013-2018: estudio de casos y controles

Introduction. Multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) is difficult to control, has high morbidity and mortality, and demands priority public health intervention. In Colombia, MDR/RR-TB has been becoming more widespread annually. Before the COVID-19 pandemic, over an 8-year period, the number of cases of multidrug-resistant tuberculosis in Colombia was close to a thousand cases. Timely identification of the different risk factors for MDR/RR-TB will contribute fundamentally to the systematic management. Objective. To determine which risk factors were associated with the presentation of MDR in Colombia between 2013 and 2018. Materials and methods. A retrospective case-control study was carried out, for which the data from the routine surveillance of MDR/events in the country were used. Results. The cases of multidrug-resistant tuberculosis were mainly in young people, Afrodescendants, and males. Of the clinical conditions, comorbidities such as malnutrition, diabetes, and HIV, presence of at least one factor, such as drug dependence, taking immunosuppressive medications, belonging to the black race, afro, and living in an area of high disease burden were risk factors. Conclusion. In addition to the diagnosis and timely provision of MDR-TB treatment, it is necessary that public health programs at the local level pay special attention to patients with the identified risk factors.

Introducción. La tuberculosis multirresistente-resistente a la rifampicina (TB-MDR/RR) es difícil de controlar, tiene una alta morbilidad y mortalidad y exige una intervención prioritaria en salud pública. En Colombia, la TB-MDR/RR se ha ido extendiendo cada año. Antes de la pandemia de COVID-19, en un periodo de 8 años, el número de casos de TB-MDR/RR en Colombia se acercaba a los mil. La identificación oportuna de los diferentes factores de riesgo de TB-MDR/RR contribuirá de manera fundamental al manejo sistemático de la enfermedad. Objetivo. Determinar los factores de riesgo que se asociaron a la presentación de la TB- MDR/RR en Colombia entre 2013 y 2018. Materiales y métodos. Se realizó un estudio retrospectivo de casos y controles, para el cual se utilizaron los datos de la vigilancia rutinaria de eventos de TB MDR/RR en el país. Resultados. Los casos de TB MDR se presentaron principalmente en jóvenes, afrodescendientes y varones. De las condiciones clínicas, fueron factores de riesgo las comorbilidades como la desnutrición, la diabetes y el VIH, y la presencia de, al menos, un factor como la farmacodependencia, el consumo de medicamentos inmunosupresores, el ser de raza negra o afro y el vivir en una zona del país de alta carga de tuberculosis. Conclusiones. Además del diagnóstico y la provisión oportuna del tratamiento de la TB MDR, es necesario que los programas de salud pública a nivel local presten especial atención a los pacientes con los factores de riesgo identificados.

Fungal Endophytes Enhance Wheat and Tomato Drought Tolerance in Terms of Plant Growth and Biochemical Parameters.

Drought is a major threat to plant growth in many parts of the world. During periods of drought, multiple aspects of plant physiology are negatively affected. For instance, water shortages induce osmotic imbalance, inhibit photosynthesis, decrease nutrient uptake, and increases the production of reactive oxygen species (ROS). In this context, it is necessary to develop sustainable strategies for crops that would help mitigate these conditions. In previous studies, endophytic Zopfiella erostrata strains were found to extensively colonize plant roots, forming a profuse melanized mycelium in the rhizosphere, which could be involved in improving water uptake and nutrient mineralization in plants. The aim of this study is to evaluate the effect of different strains of Z. erostrata on stress mitigation in wheat and tomato plants grown under water deficit conditions. General plant growth variables, as well as physiological and biochemical parameters, related to oxidative status were determined. Our data demonstrate that inoculation with both Zopfiella strains had a very significant effect on plant growth, even under water deficit conditions. However, we observed an even more pronounced impact, depending on the plant and strain involved, suggesting a certain degree of plant/strain compatibility. The biochemical aspects, the accumulation of proline, the oxidative damage to lipids, and the activity of antioxidant enzymes varied considerably depending on the endophyte and the plant evaluated.

Glioblastoma cell motility depends on enhanced oxidative stress coupled with mobilization of a sulfurtransferase.

Cell motility is critical for tumor malignancy. Metabolism being an obligatory step in shaping cell behavior, we looked for metabolic weaknesses shared by motile cells across the diverse genetic contexts of patients' glioblastoma. Computational analyses of single-cell transcriptomes from thirty patients' tumors isolated cells with high motile potential and highlighted their metabolic specificities. These cells were characterized by enhanced mitochondrial load and oxidative stress coupled with mobilization of the cysteine metabolism enzyme 3-Mercaptopyruvate sulfurtransferase (MPST). Functional assays with patients' tumor-derived cells and -tissue organoids, and genetic and pharmacological manipulations confirmed that the cells depend on enhanced ROS production and MPST activity for their motility. MPST action involved protection of protein cysteine residues from damaging hyperoxidation. Its knockdown translated in reduced tumor burden, and a robust increase in mice survival. Starting from cell-by-cell analyses of the patients' tumors, our work unravels metabolic dependencies of cell malignancy maintained across heterogeneous genomic landscapes.

Application of dry olive residue-based biochar in combination with arbuscular mycorrhizal fungi enhances the microbial status of metal contaminated soils.

Biochar made-up of dry olive residue (DOR), a biomass resulting from the olive oil extraction industry, has been proposed to be used as a reclamation agent for the recovery of metal contaminated soils. The aim of the present study was to investigate whether the soil application of DOR-based biochar alone or in combination with arbuscular mycorrhizal fungi (AMF) leads to an enhancement in the functionality and abundance of microbial communities inhabiting metal contaminated soils. To study that, a greenhouse microcosm experiment was carried out, where the effect of the factors (i) soil application of DOR-based biochar, (ii) biochar pyrolysis temperature (considering the variants 350 and 500 °C), (iii) soil application dose of biochar (2 and 5%), (iv) soil contamination level (slightly, moderately and highly polluted), (v) soil treatment time (30, 60 and 90 days) and (vi) soil inoculation with Funneliformis mosseae (AM fungus) on ß-glucosidase and dehydrogenase activities, FA (fatty acid)-based abundance of soil microbial communities, soil glomalin content and AMF root colonization rates of the wheat plants growing in each microcosm were evaluated. Biochar soil amendment did not stimulate enzyme activities but increased microbial abundances. Dehydrogenase activity and microbial abundances were found to be higher in less contaminated soils and at shorter treatment times. Biochar pyrolysis temperature and application dose differently affected enzyme activities, but while the first factor did not have a significant effect on glucosidase and dehydrogenase, a higher biochar dose resulted in boosted microbial abundances. Soil inoculation with F. mosseae favored the proliferation of soil AMF community and increased soil glomalin content as well as rates of AMF root colonization. This factor also interacted with many of the others evaluated to significantly affect soil enzyme activities, microbial abundances and AMF community. Our results indicate that the application of DOR-based biochar along with AMF fungi is an appropriate approach to improve the status of microbial communities in soils with a moderate metal contamination at short-term.

Seroprevalence of anti-SARS-CoV-2 antibodies in Colombia, 2020: A population-based study.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to cause very high morbidity and mortality throughout Latin American countries. However, few population-based seroprevalence surveys have been conducted to quantify attack rates and characterize drivers of transmission. METHODS: We conducted a population-based cross-sectional study to assess the seroprevalence of antibodies against SARS-CoV-2 in ten cities in Colombia between September and December 2020. The study involved multi-stage cluster sampling at each city. Participants provided a serum sample and answered a demographic and risk factor questionnaire. Prior infection by SARS-CoV-2 was ascertained using the "SARS-CoV-2 Total (COV2T) Advia Centaur - Siemens" chemiluminescence assay. FINDINGS: A total of 17863 participants from 7320 households participated in the study. Seroprevalence varied substantially between cities, ranging from 26% (95%CI 23-29 %) in Medellín to 68% (95%CI 62-74 %) in Guapi. There were no differences in seroprevalence by sex, but seropositivity was higher in certain ethnic groups. There was substantial heterogeneity in seroprevalence within cities, driven to a large extent by a strong association between socioeconomic stratum and seropositivity. INTERPRETATION: Colombia has been one of the Latin American countries most affected by the COVID-19 pandemic. This study documented very high attack rates in several Colombian cities by the end of 2020 and identified key drivers of heterogeneities including ethnicity and socioeconomic stratum. Few studies of seroprevalence of SARS-CoV-2 have been conducted in Latin America, and therefore this study contributes to the fundamental understanding of the pandemic in the region. FUNDING: The study was sponsored by, Ministerio de Ciencia y Tecnología e Innovación -CT361/2020, Ministerio de Salud y Protección Social, Fundación Universitaria del Norte, Imperial College of London, Universidad Nacional de Colombia (Sede Medellín), Universidad de Córdoba, California University, Unidad Nacional de Gestión del Riesgo, Centro de Atención y Diagnóstico de Enfermedades Infecciosas -CDI-, Centro Internacional de Entrenamiento e Investigaciones Médicas -CIDEIM-, Departamento Administrativo Nacional de Estadística - DANE, Fondo Nacional de Turismo -FONTUR-, Secretarías de Salud Departamentales, Distritales y Municipales and Instituto Nacional de Salud.

In vitro biological activity of extracts from marine bacteria cultures against Toxoplasma gondii and Mycobacterium tuberculosis.

AIMS: To evaluate the biological activity of extracts from cultures of marine bacteria against Toxoplasma gondii and Mycobacterium tuberculosis. METHODS AND RESULTS: Ethyl acetate extracts obtained from seven marine bacteria were tested against T. gondii GFP-RH and M. tuberculosis H37Rv. The cytotoxicity on HFF-1 cells was measured by a microplate resazurin fluorescent approach, and the haemolytic activity was determined photometrically. The extracts from Bacillus sp. (INV FIR35 and INV FIR48) affected the tachyzoite viability. The extracts from Bacillus, Pseudoalteromonas, Streptomyces and Micromonospora exhibited effects on infection and proliferation processes of parasite. Bacillus sp. INV FIR48 extract showed an minimum inhibitory concentration value of 50 µg ml-1 against M. tuberculosis H37Rv. All the extracts exhibited relatively low toxicity to HFF-1 cells and the primary culture of erythrocytes, except Bacillus sp. INV FIR35, which decreased cell viability under 20%. Liquid chromatography coupled to mass spectrometry analysis of the most active bacterial extract Bacillus sp. INV FIR48 showed the presence of peptide metabolites related to surfactin. CONCLUSIONS: The extract from culture of deep-sea Bacillus sp. INV FIR48 showed anti-T. gondii and anti-tuberculosis (TB) biological activity with low cytotoxicity. In addition, peptide metabolites were detected in the extract. SIGNIFICANCE AND IMPACT OF THE STUDY: Toxoplasmosis and TB are among the most prevalent diseases worldwide, and the current treatment drugs exhibit side effects. This study confirm that marine bacteria are on hand sources of anti-infective natural products.

Inoculation of Indigenous Arbuscular Mycorrhizal Fungi as a Strategy for the Recovery of Long-Term Heavy Metal-Contaminated Soils in a Mine-Spill Area.

Symbiotic associations with arbuscular mycorrhizal fungi (AMF) offer an effective indirect mechanism to reduce heavy metal (HM) stress; however, it is still not clear which AMF species are more efficient as bioremediating agents. We selected different species of AMF: Rhizoglomus custos (Custos); Rhizoglomus sp. (Aznalcollar); and Rhizophagus irregularis (Intraradices), in order to study their inoculation in wheat grown in two soils contaminated with two levels of HMs; we tested the phytoprotection potential of the different AMF symbioses, as well as the physiological responses of the plants to HM stress. Plants inoculated with indigenous Aznalcollar fungus exhibited higher levels of accumulation, mainly in the shoots of most of the HM analyzed in heavily contaminated soil. However, the plants inoculated with the non-indigenous Custos and Intraradices showed depletion of some of the HM. In the less-contaminated soil, the Custos and Intraradices fungi exhibited the greatest bioaccumulation capacity. Interestingly, soil enzymatic activity and the enzymatic antioxidant systems of the plant increased in all AMF treatments tested in the soils with both degrees of contamination. Our results highlight the different AMF strategies with similar effectiveness, whereby Aznalcollar improves phytoremediation, while both Custos and Intraradices enhance the bioprotection of wheat in HM-contaminated environments.

Design of Bio-Absorbent Systems for the Removal of Hydrocarbons from Industrial Wastewater: Pilot-Plant Scale.

The objective of this study was the development and design of a treatment system at a pilot-plant scale for the remediation of hydrocarbons in industrial wastewater. The treatment consists of a combined approach of absorption and biodegradation to obtain treated water with sufficient quality to be reused in fire defense systems (FDSs). The plant consists of four vertical flow columns (bioreactors) made of stainless steel (ATEX Standard) with dimensions of 1.65 × 0.5 m and water volumes of 192.4 L. Each bioreactor includes a holder to contain the absorbent material (Pad Sentec polypropylene). The effectiveness of the treatment system has been studied in wastewater with high and low pollutant loads (concentrations higher than 60,000 mg L-1 of total petroleum hydrocarbons (TPH) and lower than 500 mg L-1 of TPHs, respectively). The pilot-plant design can function at two different flow rates, Q1 (180 L h-1) and Q2 (780 L h-1), with or without additional aeration. The results obtained for strongly polluted wastewaters showed that, at low flow rates, additional aeration enhanced hydrocarbon removal, while aeration was unnecessary at high flow rates. For wastewater with a low pollutant load, we selected a flow rate of 780 L h-1 without aeration. Different recirculation times were also tested along with the application of a post-treatment lasting 7 days inside the bioreactor without recirculation. The microbial diversity studies showed similar populations of bacteria and fungi in the inlet and outlet wastewater. Likewise, high similarity indices were observed between the adhered and suspended biomass within the bioreactors. The results showed that the setup and optimization of the reactor represent a step forward in the application of bioremediation processes at an industrial/large scale.

Patient- and provider-related factors in the success of multidrug-resistant tuberculosis treatment in Colombia.

OBJECTIVE: To identify patient- and provider-related factors associated with the success of multidrug-resistant tuberculosis (MDR-TB) treatment in the six municipalities of Colombia with the highest number of MDR-TB cases. METHODS: Bivariate and multivariate logistic regressions were used to analyze the association between treatment success (cure or treatment completion) and characteristics of the patients and physicians, nursing professionals, and psychologists involved in their treatment. The importance of knowledge in the management of MDR-TB cases was explored through focus groups with these providers. RESULTS: Of 128 cases of TB-MDR, 63 (49.2%) experienced treatment success. Only 52.9% of the physicians and nursing professionals had satisfactory knowledge about MDR-TB. Logistic regression showed that being HIV negative, being affiliated with the contributory health insurance scheme, being cared for by a male physician, and being cared for by nursing professionals with sufficient knowledge were associated with a successful treatment outcome (p ≤ 0.05). Qualitative analysis showed the need for in-depth, systematic training of health personnel who care for patients with MDR-TB. CONCLUSIONS: Some characteristics of patients and healthcare providers influence treatment success in MDR-TB cases. Physicians' and nurses' knowledge about MDR-TB must be improved, and follow-up of MDR-TB patients who are living with HIV and of those affiliated with the subsidized health insurance scheme in Colombia must be strengthened, as these patients have a lower likelihood of a successful treatment outcome.

Gradual Deprogramming of Self-Inflicted Oral Trauma Habit in a Child with Cerebral Palsy.

The purpose of this paper is to report the successful noninvasive treatment of a self-inflicted traumatic lesion on the lower labial mucosa in a 22-month-old boy with cerebral palsy. An acrylic appliance was cemented on the anterior maxillary region to reduce repetitive self-injury by gradual deprogramming. The wound healed after a few weeks, but four weeks after the appliance was removed new trauma was observed at the site. The appliance was replaced by a new one on the anterior region of the mandibular arch, and complete remission of the habit was achieved after three weeks. In order to prevent relapse, the appliance was gradually reduced in size with carbide drills every two weeks and was removed three weeks after the final reduction. After 24 months of follow-up, the labial mucosa was completely healed and no recurrence of the traumatic habit has been observed.

A análise qualitativa demonstrou necessidade de aprofundar e sistematizar a capacitação do pessoal de saúde que atende casos de TBMR. Conclusões. Algumas características do paciente e da equipe de saúde influenciam no êxito do tratamento de casos de TBMR. É preciso fortalecer os conhecimentos dos médicos e profissionais de enfermagem sobre a TBMR e reforçar o seguimento dos pacientes com TBMR que vivem com HIV e os filiados ao sistema de saúde colombiano pelo regime subsidiado, os quais têm menor probabilidade de êxito do tratamento.

Relationship between depression, alcohol and / or tobacco abuse of those responsible and children's oral health

Objective :To investigate the influence of parental depression and smoking and alcohol use by parents/caregivers use on oral health in children aged 5-11 years of both sexes. Methods: A cross-sectional study was conducted involving 85 children and their parents/caregivers. Adult respondents completed three questionnaires to assess depression and alcohol and tobacco use: two versions of the PHQ (PatientHealth Questionnaire; PHQ-2 and PHQ-9), AUDIT (Alcohol Use DisordersIdentification Test) for risk assessment of alcohol dependence and abuse, and the Fagerström Test for Nicotine Dependence (FTND). The PHQ-2 contained two questions requiring an affirmative or negative answer. Children underwent oral examinations to evaluate biofilm control, gingival bleeding and caries index, specifically DMFT index. Relationships among variables were evaluated using chi-squared tests and Fisher's exact test. Results: Only 10.6% of parents and caregivers consumed tobacco and 24,7% of parents or caregivers manifested depressive symptoms. Regarding alcohol consumption, 10.6% of caregivers presented risk consumption or dependence. A positive association was found between children'sgingival bleeding and their caregivers' risk of alcohol dependence (p=0.038). Conclusion: A positive association between caregivers' risk of alcohol dependence and the presence of gingival bleeding in children was found. Caregivers' depression and alcohol and tobacco use did not influence children's caries.

Objetivo: Investigar a influência da depressão parental e do uso de cigarro e álcool pelos pelos pais/cuidadores na saúde bucal de crianças de 5 a 11 anos de ambos os sexos. Métodos: Um estudo do tipo transversal foi conduzido com 85 crianças e seus respectivos cuidadores. Para detectar a presença de depressão, duas versões do PHQ (Pacient Health Questionnaire) foram aplicadas: o PHQ-2, contendo duas perguntas com opção de resposta afirmativa ou negativa e o segundo, PHQ-9. Para o uso de álcool foi aplicado o AUDIT (Alcohol Use Disorders Identification Test) para avaliação do risco de dependência e abuso de álcool; e o Fagerstrom para dependência de nicotina. As crianças foram submetidas a exames orais para avaliação do controle de biofilme, sangramento gengival e presença de cárie (índices CPO-D e ceo-d). Para verificar a associação entre as diferentes variáveis, foram utilizados os testes Qui-quadrado e Exato de Fisher. Resultados: Somente 10,6% dos responsáveis faziam uso de tabaco e 24,7% dos mesmos apresentavam sintomas de depressão. Em relação ao consumo de álcool, 10,6% apresentavam consumo de risco ou dependência. Verificou-se associação entre sangramento gengival nas crianças e o risco de dependência de álcool dos responsáveis (p=0,038). Conclusão: Concluiu-se que há uma associação positiva entre o risco de dependência de álcool dos responsáveis e a presença de sangramento gengival no paciente e que a depressão, o uso de álcool e de tabaco pelos cuidadores não influência na experiência de cárie das crianças.
