RESUMEN

The combination of a low-density geochemical survey, multispectral data obtained with Unmanned Aerial Vehicle-Remote Sensing (UAV-RS), and a machine learning technique was tested in the search for a statistically robust prediction of contaminant distribution in soil and vegetation, for zones with a highly variable pollutant load. To this end, a novel methodology was devised by means of a limited geochemical study of topsoil and vegetation combined with multispectral data obtained by UAV-RS. The methodology was verified in an area affected by Hg and As contamination that typifies abandoned mining-metallurgy sites in recent decades. A broad selection of spectral indices were calculated to evaluate soil-plant system response, and four machine learning techniques (Multiple Linear Regression, Random Forest, Generalized Boosted Models, and Multivariate Adaptive Regression Spline) were tested to obtain robust statistical models. Random Forest (RF) provided the best non-biased models for As and Hg concentration in soil and vegetation, with R2 and rRMSE (%) ranging from 0.501 to 0.630 and from 180.72 to 46.31, respectively, and with acceptable values for RPD and RPIQ statistics. The prediction and mapping of contaminant content and distribution in the study area were well enough adjusted to the geochemical data and revealed superior accuracy for As than Hg, and for vegetation than topsoil. The results were more precise than those obtained in comparable studies that applied satellite or spectrometry data. In conclusion, the methodology presented emerges as a powerful tool for studies addressing soil and vegetation pollution and an alternative approach to classical geochemical studies, which are time-consuming and expensive.

RESUMEN

BACKGROUND: Metastatic small bowel adenocarcinoma (SBA) has a poor prognosis. Due to its rarity, high-quality data are lacking to guide treatment. This retrospective analysis was conducted to help characterize the treatment options for patients with metastatic SBA while providing clinically meaningful prognostic information. PATIENTS AND METHODS: In total, 437 patients who initially presented with or developed metastatic SBA between September 1977 and September 2019 were identified from the MD Anderson Tumor Registry. Clinical data were collected from review of the medical record. Overall response rates (ORR), time to progression (TTP), and overall survival (OS) were assessed across various treatments and treatment lines. RESULTS: The median OS from diagnosis of metastatic disease was 15.9 months [95% confidence interval (CI): 14.3-17.9]. Seventy-five patients (17.1%) underwent metastasectomy, which was associated with a median OS of 34.5 versus 17.1 months among patients who received chemotherapy alone (P < 0.001). Fluoropyrimidine plus platinum (n = 164) was the most common first-line chemotherapy, associated with an ORR of 59% and TTP of 8.1 months. Irinotecan with 5-FU (n = 101) was the most common second-line therapy associated with an ORR of 31% and TTP of 4.0 months. Twenty-two patients received immunotherapy; 5 of 6 patients with deficient mismatch repair (dMMR) responded, while 0 of 16 with proficient mismatch repair (pMMR) responded. Taxane-based chemotherapy was given to 34 patients with an ORR of 21% and a median TTP of 2.4 months. Among 11 patients who received anti-epidermal-growth-factor-receptor (EGFR) monotherapy, the best response was stable disease (SD) in 1 patient. CONCLUSIONS: In well-selected patients with SBA, metastasectomy appears to be associated with improved OS. This improvement was seen across metastasectomy sites, including liver, lung and peritoneal. Anti-programmed cell death protein 1 (PD-1) based immunotherapy was active for dMMR SBA but not pMMR SBA. While taxane-based chemotherapy demonstrates therapeutic activity, the activity of anti-EGFR therapy was limited.

RESUMEN

Aims to investigate the effects of grape seed proanthocyanidin extract (GSPE) on production performance, metabolism, and anti-oxidative status of Holstein dairy cattle in early lactation. Forty-eight multiparous Holstein dairy cattle were assigned to four groups (CON, G20, G40 and G80) and supplied with 0, 20, 40, and 80mg GSPE/kg of body weight/day. G20 significantly increased milk yield compared with other groups. Milk protein and non-fat-solids were increased in G20, G40 and G80 groups compared with the control group only at the 7th day during the experiment. No significant difference was observed in milk fat and somatic cell count, nor on parameters of energy metabolism in blood, liver function and kidney function between the four groups. There was no significant difference in glutathione peroxidase, superoxide dismutase, total antioxidant capacity, and hydrogen peroxide between the groups; but the malondialdehyde content of G20 significantly increased at day 14 in comparison with CON, and tended to increase at the 28th day. In conclusion, feeding 20mg GSPE/kg of body weight/day was associated with a significant increase in milk yield without detrimental effects on liver or kidney function and with substantial energy metabolism and antioxidant parameters improvement in early lactation dairy cattle.(AU)


O presente trabalho visa investigar os efeitos do extrato de semente de uva Proanthocyanidin (GSPE) sobre o desempenho da produção, o metabolismo e o status antioxidante de gado leiteiro Holstein em lactação precoce. Quarenta e oito vacas leiteiras multíparas Holstein foram divididas em quatro grupos (CON, G20, G40 e G80) e receberam 0, 20, 40 e 80mg de GSPE/kg de peso corporal/dia, respectivamente. O G20 aumentou significativamente o rendimento do leite em comparação com os outros grupos. A proteína e os sólidos não gordurosos do leite foram aumentados nos grupos G20, G40 e G80 somente no sétimo dia durante a experiência. Não foi observada diferença significativa na gordura do leite e na contagem de células somáticas, bem como nos parâmetros de metabolismo energético no sangue, na função hepática e na função renal entre os grupos em relação ao grupo controle. Não houve diferença significativa na glutationa peroxidase, na dimutase de superóxido, na capacidade antioxidante total e no peróxido de hidrogênio entre os grupos, mas o conteúdo malondialdeído do G20 aumentou significativamente no dia 14 em comparação com o CON, e tendia a aumentar no dia 28. Em conclusão, a alimentação de 20mg de GSPE/kg de peso corporal/dia foi associada a um aumento significativo no rendimento do leite, sem efeitos nocivos sobre a função hepática ou a renal, com o metabolismo de energia substancial e a melhoria dos parâmetros antioxidantes de gado leiteiro no início da lactação.(AU)

RESUMEN

BACKGROUND@# The capability of the public ambulance system in Ukraine to address urgent medical complaints in a prehospital environment is unknown. Evaluation using reliable sources of patient data is needed to provide insight into current treatments and outcomes.@*METHODS@# We obtained access to de-identified computer records from the emergency medical services (EMS) dispatch center in Poltava, a medium-sized city in central Ukraine. Covering a fivemonth period, we retrieved data for urgent calls with a patient complaint of respiratory distress. We evaluated ambulance response and treatment times, field diagnoses, and patient disposition, and analyzed factors related to fatal outcomes.@*RESULTS@#Over the five-month period of the study, 2,029 urgent calls for respiratory distress were made to the Poltava EMS dispatch center. A physician-led ambulance typically responded within 10 minutes. Seventy-seven percent of patients were treated and released, twenty percent were taken to hospital, and three percent died in the prehospital phase. On univariate analysis, age over 60 and altered mental status at the time of the call were strongly associated with a fatal outcome.@*CONCLUSION@# The EMS dispatch center in a medium-sized city in Ukraine has adequate organizational infrastructure to ensure that a physician-led public ambulance responds rapidly to complaints of respiratory distress. That EMS system was able to manage most patients without requiring hospital admission. However, a prehospital fatality rate of three percent suggests that further research is warranted to determine training, equipment, or procedural needs of the public ambulance system to manage urgent medical conditions.

RESUMEN

This work reports a simple voltammetric method for the determination of chloride, bromide, and iodide ions using screen-printed carbon electrodes modified with silver nanoparticles electrochemically deposited on the working electrode surface. UV/Vis absorption spectroelectrochemistry was used to study the electrodeposition of silver nanoparticles on the working carbon electrode on PET or Gore-Tex® supports, and their subsequent oxidation in the presence of halide ions. The main figures of merit of the developed sensors, such as reproducibility and detection limit, have been calculated. Reproducibility values of 2.22%, 2.83% and 3.23% were obtained for chloride, bromide and iodide determinations, respectively. Additionally, the lowest detected amount of chloride, bromide and iodide ions were 3.0·10-6 M, 5.0·10-6 M and 5.0·10-6 M, respectively. Taking into account the relevance of the determination of chloride ion concentration in sweat, the voltammetric method for the determination of halides has been successfully transferred to a Gore-Tex® support to build a first approach to a wearable sensor that facilitates the quantification of this ion in sweat samples. The Gore-Tex® sensor provides a good reproducibility (RSD = 1.61%).

RESUMEN

BACKGROUND: Understanding the impact of effective paediatric adherence promotion interventions on patients, families and the healthcare system is necessary to inform efforts to improve healthcare quality and control costs. Building on previous research suggesting that improving adherence may have far-reaching benefits, the objective of this study was to quantify the impact of effective adherence promotion interventions for children and adolescents with a chronic medical condition on patients, families and the healthcare system. METHODS: Authors systematically reviewed articles indexed in PubMed, PsycINFO and CINAHL to identify randomized controlled trials of paediatric adherence promotion interventions. Interventions that improved paediatric adherence and examined patient-level, family-level or healthcare system-level outcomes in children and adolescents (M age ≤ 18 years) with a chronic medical condition were included. Two authors independently extracted and classified outcome variables as patient-level (quality of life and disease-related activity restrictions), micro-level (family functioning, family conflict, caregiver quality of life, caregiver sleep interruption, caregiver days away from work and patient missed school days) or macro-level variables (emergency department visits, hospitalizations, outpatient visits and urgent care visits). Outcome variables detailed in previously published reviews (i.e. disease severity) were excluded. RESULTS: Twenty studies representing 19 unique samples met inclusion criteria. An additional eight articles representing trials that did not significantly improve adherence were included in post hoc analyses. Compared with control interventions, effective paediatric adherence promotion interventions improved patient quality of life and family-level outcomes and decreased healthcare utilization among children and adolescents with a chronic medical condition. CONCLUSIONS: Interdisciplinary efforts to improve healthcare quality and reduce spending among children and adolescents with a chronic medical condition may be enhanced by incorporating effective paediatric adherence promotion interventions. As relatively few chronic medical conditions were represented in included studies, future research should examine the impact of paediatric adherence promotion interventions in other populations.

RESUMEN

BACKGROUND: Retrospective studies have reported the occurrence of nonconvulsive seizures in critically ill children. We aimed to prospectively determine the incidence and risk factors of nonconvulsive seizures in critically ill children using predetermined EEG monitoring indications and EEG interpretation terminology. METHODS: Critically ill children (non-neonates) with acute encephalopathy underwent continuous EEG monitoring if they met institutional clinical practice criteria. Study enrollment and data collection were prospective. Logistic regression analysis was utilized to identify risk factors for seizure occurrence. RESULTS: One hundred children were evaluated. Electrographic seizures occurred in 46 and electrographic status epilepticus occurred in 19. Seizures were exclusively nonconvulsive in 32. The only clinical risk factor for seizure occurrence was younger age (p=0.03). Of patients with seizures, only 52% had seizures detected in the first hour of monitoring, while 87% were detected within 24 hours. CONCLUSIONS: Seizures were common in critically ill children with acute encephalopathy. Most were nonconvulsive. Clinical features had little predictive value for seizure occurrence. Further study is needed to confirm these data in independent high-risk populations, to clarify which children are at highest risk for seizures so limited monitoring resources can be allocated optimally, and to determine whether seizure detection and management improves outcome.

RESUMEN

A copy of the bovine chymosin gene (chy) with a codon usage optimized for its expression in Aspergillus awamori was constructed starting from synthetic oligonucleotides. To study the ability of this filamentous fungus to secrete bovine prochymosin, two plasmids were constructed in which the transcriptional, translational, and secretory control regions of the A. nidulans gpdA gene and pepB genes were coupled to either preprochymosin or prochymosin genes. Secretion of a protein enzymatically and immunologically indistinguishable from bovine chymosin was achieved in A. awamori transformants with each of these constructions. In all cases, the primary translation product (40.5 kDa) was self-processed to a mature chymosin polypeptide having a molecular weight of 35.6 kDa. Immunological assays indicated that most of the chymosin was secreted to the extracellular medium. Hybridization analysis of genomic DNA from chymosin transformants showed chromosomal integration of prochymosin sequences and, in some transformants, multiple copies of the expression cassettes were observed. Expression from the gpdA promoter was constitutive, whereas expression from the pepB promoter was strongly influenced by pH. A very high expression from the pepB promoter was observed during the growth phase. The A. awamori pepB gene terminator was more favorable for chymosin production than the S. cerevisiae CYC1 terminator.

RESUMEN

A new methodology is presented to offer the possibility of simultaneously obtaining two different spectroscopic signals in a single spectroelectrochemical experiment. Taking the plane of the electrode surface as a spatial reference, normal-beam and parallel-beam UV-vis absorbance signals are jointly analyzed, revealing important experimental differences between the two kinds of signals. Two different chemical systems are selected to show the possibilities of the bidimensional spectroelectrochemistry: a simple diffusive process and an adsorptive electrode reaction. Comparative results show clearly that the two kinds of spectroscopic signals, both normal and parallel to the electrode surface, have to be used together in the study of any electrode reaction scheme.

El objetivo del trabajo fue evaluar la eficacia y tolerancia de glimepirida en pacientes con diagnóstico de Diábetes Mellitus tipo 2 en Venezuela. Mediante un estudio multicéntrico abierto, no randomizado, prospectivo, de Glimepirida en pacientes diabéticos tipo 2. Dosis de inicio: 1 mg de glimepirida, de acuerdo a las respuesta se aumenta la dosis en 1 mg cada 2 semanas hasta alcanzar una glicemia en ayunas menor o igual a 140 mg/dl. El período total de observación fue de 12 semanas. Se realizó un control cada dos semanas. Se estudió una muestra de 258 pacientes diabéticos tipo 2 que no estaban controlados adecuadamente con dieta, ejercicios y/o tratamiento hipoglicemiante, quienes recibieron glimepirida por primera vez o cambiaron su tratamiento a glimepirida. Todos los datos se analizaron mediante la prueba T de Student con dos colas. Se consideró resultado estadísticamente significativo a los valores de p<0.05 en lo que se refiere a disminución de glicemia por cada consulta. Al inicio del estudio la glicemia en ayunas se encontraba en valores de 225,55 ñ 67 mg/dl. Al término del estudio la glicemia obtenida fue 127,80 ñ 42 mg/dl. La glicemia disminuyo en promedio un 44 por ciento luego de 12 semanas de tratamiento. 93 por ciento de casos lograron control adecuado de la glicemia. No se presentaron efectos secundarios en 91 por ciento de los casos. Ocurrieron reacciones adversas en 21 pacientes (9 por ciento de los casos), de los cuales 11 casos corresponden a episodios de hipoglicemia. La hipoglicemia fue leve o moderada en todos los casos no ameritando hospitalización. Glimepirida demostró eficacia terapéutica al disminuir los niveles de glicemia en ayunas a valores menores o iguales a 140 mg/dl en el 79,53 por ciento de los pacientes, significativo estadísticamente, con un excelente perfíl de seguridad (91 por ciento de los casos no reportaron efectos secundarios

RESUMEN

The biosynthetic gene cluster for the 26-membered ring of the polyene macrolide pimaricin extends for about 110 kilobase pairs of contiguous DNA in the genome of Streptomyces natalensis. Two sets of polyketide synthase (PKS) genes are separated by a group of small polyketide-functionalizing genes. Two of the polyketide synthase genes, pimS0 and pimS1, have been fully sequenced and disrupted proving the involvement of each of these genes in pimaricin biosynthesis. The pimS0 gene encodes a relatively small acetate-activating PKS (approximately 193 kDa) that appears to work as a loading protein which "presents" the starter unit to the second PKS subunit. The pimS1 gene encodes a giant multienzyme (approximately 710 kDa) harboring 15 activities responsible for the first four cycles of chain elongation in pimaricin biosynthesis, resulting in formation of the polyene chromophore.

RESUMEN

Ultrastructural examinations of sites where Candida albicans invaded the bowel wall after oral intragastric inoculation of infant mice suggested that blastoconidia are capable of progressive extracellular digestion of the intestinal mucus barrier. Microplate assay methods, based on biotin or digoxigenin-labelling systems, were therefore devised for quantitation of protease and glycosidase activities against the glycoprotein mucin. Labelled mucin was adsorbed on microplate wells, incubated with sample to be assayed for enzyme activity, and the remaining labelled mucin was quantitated by spectrophotometry. Proteolytic activity against mucin was demonstrated using concentrated culture filtrate of C. albicans strain LAM-1, grown in yeast nitrogen base medium containing mucin as sole nitrogen source. The activity was inhibited by boiling for 10 min or by incubation with the aspartyl proteinase inhibitor pepstatin A.

RESUMEN

A zone of extracellular digestion of the mucin layer around Candida albicans blastoconidia was observed by transmission electron microscopy in the jejunum of mice inoculated intragastrically (G. T. Cole, K. R. Seshan, L. M. Pope, and R. J. Yancey, J. Med. Vet. Mycol. 26:173-185, 1988). This observation prompted the hypothesis that a putative mucinolytic enzyme(s) may contribute to the virulence of C. albicans by facilitating penetration of the mucus barrier and subsequent adherence to and invasion of epithelial cells. Mucinolytic activity was observed as zones of clearing around colonies of C. albicans LAM-1 grown on agarose containing yeast nitrogen base, glucose, and hog gastric mucin. In addition, concentrated culture filtrate obtained after growth for 24 h in yeast nitrogen base, supplemented with glucose and mucin as the sole nitrogen source, contained proteolytic activity against biotin-labelled mucin which was inhibited by pepstatin A. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the culture filtrate revealed two components of 42 and 45 kDa, with pIs of 4.1 and 5.3, respectively. A zymogram showed that mucin was degraded only by the 42-kDa component, which was also recognized by immunoblotting with an anti-secretory aspartyl proteinase (anti-Sap) 2p monoclonal antibody. The N-terminal sequence of the first 20 amino acids matched that reported for Sap2p. These results demonstrate that Sap2p is responsible for proteolysis of mucin by C. albicans in vitro and may be involved as a virulence factor in the breakdown of mucus and penetration of the mucin barrier by C. albicans.
