RESUMO

Among pollution remediation technologies, advanced oxidation processes (AOPs) are genuinely efficient since they are based on the production of strong, non-selective oxidants, mainly hydroxyl radicals (·OH), by a set of physicochemical methods. The biological counterparts of AOPs, which may be referred to as advanced bio-oxidation processes (ABOPs), have begun to be investigated since the mechanisms of induction of ·OH production in fungi are known. To contribute to the development of ABOPs, advanced oxidation of a wide number of dyes by the white-rot fungus Pleurotus eryngii, via a quinone redox cycling (QRC) process based on Fenton's reagent formation, has been described for the first time. The fungus was incubated with 2,6-dimethoxy-1,4-benzoquinone (DBQ) and Fe3+-oxalate, with and without Mn2+, leading to different ·OH production rates, around twice higher with Mn2+. Thanks to this process, the degradative capacity of the fungus increased, not only oxidising dyes it was not otherwise able to, but also increasing the decolorization rate of 20 dyes by more than 7 times in Mn2+ incubations. In terms of process efficacy, it is noteworthy that with Mn2+ the degradation of the dyes reached values of 90-100% in 2-4 h, which are like those described in some AOPs based on the Fenton reaction.

RESUMO

BACKGROUND: Patients with hypotension usually receive intravenous fluids, but only 50% will respond to fluid administration. We aimed to assess the intra and interobserver agreement to evaluate fluid tolerance through diverse ultrasonographic methods. METHODS: We prospectively included critically ill patients on mechanical ventilation. One trained intensivist and two intensive care residents obtained the left ventricular outflow tract velocity-time integral (VTI) variability, inferior vena cava (IVC) distensibility index, internal jugular vein (IJV) distensibility index, and each component of the venous excess ultrasound (VExUS) system. We obtained the intraclass correlation coefficient (ICC) and Gwet's first-order agreement coefficient (AC1), as appropriate. RESULTS: We included 32 patients. In-training observers were unable to assess the VTI-variability in two patients. The interobserver agreement was moderate to evaluate the IJV-distensibility index (AC1 0.54, CI 95% 0.29-0.80), fair to evaluate VTI-variability (AC1 0.39, CI 95% 0.12-0.66), and absent to evaluate the IVC-distensibility index (AC1 0.19, CI 95% - 0.07 to 0.44). To classify patients according to their VExUS grade, the intraobserver agreement was good, and the interobserver agreement was moderate (AC1 0.52, CI 95% 0.34-0.69). CONCLUSIONS: Point-of-care ultrasound is frequently used to support decision-making in fluid management. However, we observed that the VTI variability and IVC-distensibility index might require further training of the ultrasound operators to be clinically useful. Our findings suggest that the IJV-distensibility index and the VExUS system have acceptable reproducibility among in-training observers.

RESUMO

Microplastic (MP)-colonizing microorganisms are important links for the potential impacts on environmental, health, and biochemical circulation in various ecosystems but are not yet well understood. In addition, biofilms serve as bioindicators for the evaluation of pollutant effects on ecosystems. This study describes the ability of three polyethylene-type microplastics, white (W-), blue (B-), and fluorescent blue (FB-) MPs, to support microbial colonization of Pseudomonas aeruginosa, the effect of mixed organic contaminants (OCs: amoxicillin, ibuprofen, sertraline, and simazine) on plastic-associated biofilms, and the role of biofilms as transfer vectors of such emerging pollutants. Our results showed that P. aeruginosa had a strong ability to produce biofilms on MPs, although the protein amount of biomass formed on FB-MP was 1.6- and 2.4-fold higher than that on B- and W-MP, respectively. When OCs were present in the culture medium, a decrease in cell viability was observed in the W-MP biofilm (65.0%), although a general impairing effect of OCs on biofilm formation was ruled out. Microbial colonization influenced the ability of MPs to accumulate OCs, which was higher for FB-MP. In particular, the sorption of amoxicillin was lower for all bacterial-colonized MPs than for the bare MPs. Moreover, we analysed oxidative stress production to assess the impact of MPs or MPs/OCs on biofilm development. The exposure of biofilms to OCs induced an adaptive stress response reflected in the upregulation of the katB gene and ROS production, particularly on B- and FB-MP. This study improves our understanding of MP biofilm formation, which modifies the ability of MPs to interact with some organic pollutants. However, such pollutants could hinder microbial colonization through oxidative stress production, and thus, considering the key role of biofilms in biogeochemical cycles or plastic degradation, the co-occurrence of MPs/OCs should be considered to assess the potential risks of MPs in the environment.

RESUMO

Introduction: Laparoscopic resection of the pancreas (LRP) has been implemented to a varying degree because it is technically demanding and requires a long learning curve. In the present study we analyze the risk factors for complications and hospital readmissions in a single center study of 105 consecutive LRPs. Methods: We conducted a retrospective study using a prospective database. Data were collected on age, gender, BMI, ASA score, type of surgery, histologic type, operative time, hospital stay, postoperative complications, degree of severity and hospital readmission. Results: The cohort included 105 patients, 63 females and 42 males with a median age and BMI of 58 (53–70) and 25.5 (22,2–27.9) respectively. Eighteen (17%) central pancreatectomies, 5 (4.8%) enucleations, 81 (77.6%) distal pancreatectomies and one total pancreatectomy were performed. Fifty-six patients (53.3%) experienced some type of complication, of which 13 (12.3%) were severe (Clavien-Dindo > IIIb) and 11 (10.5%) patients were readmitted in the first 30 days after surgery. In the univariate analysis, age, male gender, ASA score, central pancreatectomy and operative time were significantly associated with the development of complications (P <0.05). In the multivariate analysis, male gender (OR 7.97; 95% CI 1.08–58.88)), severe complications (OR 59.40; 95% CI, 7.69–458.99), and the development of intrabdominal collections (OR 8.97; 95% CI, 1.28–63.02)) were associated with hospital readmission. Conclusions: Age, male gender, ASA score, operative time and central pancreatectomy are associated with a higher incidence of complications. Male gender, severe complications and intraabdominal collections are associated with more hospital readmissions. (AU)

RESUMO

The globalization of the market, as well as the increasing world population, which require a higher demand for food products, pose a great challenge to ensure food safety and prevent food loss and waste. In this sense, active materials with antibacterial properties are an important alternative in the prolongation of shelf life and ensuring food safety. In this work, the ability of copper(II) hydroxy nitrate (CuHS) to obtain antibacterial films based on low density polyethylene (LDPE) and polylactic acid (PLA), was evaluated. The thermal properties of the composites, evaluated using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), showed that the concentrations of added CuHS do not particularly change these characteristics with respect to the neat polymer matrix films. The mechanical properties, determined using dynamic mechanical analysis (DMTA), indicate a small increase in the brittleness of the material in PLA-based composites. The antibacterial properties against Listeria monocytogenes and Salmonella enterica were evaluated using a surface contact test, and a bacterial reduction of at least 8 to 9 logarithmic units for the composites with 0.3% CuHS, both in LDPE and PLA and against both bacteria, were achieved. The reusability of the composite films after their first use demonstrated a higher stability against Listeria monocytogenes. The migration and cytotoxicity of the composites loaded with 0.3% CuHS was evaluated, demonstrating the safety of these materials, which reinforces their potential use in food packaging applications.

RESUMO

PURPOSE: We evaluated the renal arterial resistive index (RRI), urine monocyte chemotactic protein 1 (uMCP-1), and urine neutrophil gelatinase-associated lipocalin (uNGAL) to predict acute kidney injury (AKI) in critically ill cancer patients. METHODS: In this prospective study, we included patients without AKI. We compared the area under the curve (AUC) of RRI, uMCP-1, and uNGAL to predict any stage of AKI and stage-3 AKI with the DeLong method, and we established cutoff points with the Youden index. RESULTS: We included 64 patients, and 43 (67.2%) developed AKI. The AUC to predict AKI were: 0.714 (95% CI 0.587-0.820) for the RRI, 0.656 (95% CI 0.526-0.770) for uMCP-1, and 0.677 (95% CI 0.549-0.789) for uNGAL. The AUC to predict stage-3 AKI were: 0.740 (95% CI 0.615-0.842) for the RRI, 0.757 (95% CI 0.633-0.855) for uMCP-1, and 0.817 (95% CI 0.701-0.903) for uNGAL, without statistical differences among them. For stage 3 AKI prediction, the sensitivity and specificity were: 56.3% and 87.5% for a RRI > 0.705; 70% and 79.2% for an uMCP-1 > 2169 ng/mL; and 87.5% and 70.8% for a uNGAL > 200 ng/mL. The RRI was significantly correlated to age (r = 0.280), estimated glomerular filtration rate (r = - 0.259), mean arterial pressure (r = - 0.357), and serum lactate (r = 0.276). CONCLUSION: The RRI, uMCP-1, and uNGAL have a similar ability to predict AKI. The RRI is more specific, while urine biomarkers are more sensitive to predict stage 3 AKI. The RRI correlates with hemodynamic variables. The novel uMCP-1 could be a useful biomarker that needs to be extensively studied.

RESUMO

Enzyme immobilization on adequate carriers is a challenging strategy. Understanding the enzyme-carrier interactions and their effects on enzyme conformation and bioactivity is critical. In this study, a meso-macropores silica (MMS) was used to immobilize ß-galactosidase from the yeast Kluyveromyces lactis (ß-gal-KL) by physical adsorption. The bioactivity of the immobilized ß-gal-KL was altered, evidenced by the increased Km , decreased Vmax and kcat , and increased activity at alkaline values. By performing infrared spectroscopy analysis and subsequent secondary structure assessment from the amide I band, the immobilized ß-gal-KL suffered a ß-sheet (∼31-35 %) to α-helix (∼15-19 %) transition with increased turns (∼21-22 %) with respect to the free ß-gal-KL having ∼12 % α-helix, ∼42 % ß-sheet, and ∼17 % turns. These findings led us to correlate the observed bioactivity performance to structural alterations to a non-native conformation. The presented line of thought can lead to a better understanding of the reasons causing bioactivity alterations upon enzyme immobilization.

RESUMO

The globalization of the market and the increase of the global population that requires a higher demand of food products superimposes a big challenge to ensure food safety. In this sense, a common strategy to extend the shelf life and save life of food products is by avoiding bacterial contamination. For this, the development of antibacterial contact surfaces is an urgent need to fulfil the above-mentioned strategy. In this work, the role of MXene (Ti3C2Tx) in providing antibacterial contact surfaces was studied through the creation of composite films from polylactic acid (PLA), as the chosen polymeric matrix. The developed PLA/MXene films maintained the thermal and mechanical properties of PLA and also presented the attractive antibacterial properties of MXene. The composites' behaviour against two representative foodborne bacteria was studied: Listeria mono-cytogenes and Salmonella enterica (representing Gram-positive and Gram-negative bacteria, respectively). The composites prevented bacterial growth, and in the case of Listeria only 0.5 wt.% of MXene was necessary to reach 99.9999% bactericidal activity (six log reductions), while against Salmonella, 5 wt.% was necessary to achieve 99.999% bactericidal activity (five log reductions). Cy-totoxicity tests with fHDF/TER166 cell line showed that none of the obtained materials were cytotoxic. These results make MXene particles promising candidates for their use as additives into a polymeric matrix, useful to fabricate antibacterial contact surfaces that could prove useful for the food packaging industry.

RESUMO

OBJECTIVE: To determine the outcomes of hospitalized cancer patients requiring intensive care unit (ICU) intervention and receiving palliative care. MATERIALS AND METHODS: An observational retrospective study was completed at a single academic critical care unit in Mexico City. All hospitalized cancer patients who were evaluated by the intensive care team to assess need for ICU were included between January and December 2018. RESULTS: During the study period, the ICU group made 408 assessments of critically ill cancer patients in noncritical hospitalized areas. In total, 24.2% (99/408) of the patients in this population were consulted by the palliative care team. Of the patients evaluated, 46.5% (190/408) had advanced stage, but only 28.4% were receiving care by the palliative care team. The only risk factor for hospital mortality in the multivariate analysis was the quick Sequential Organ Failure Assessment (qSOFA) score at the time of the consultation by the ICU group (HR = 2.10, 95% CI = 1.34-3.29, p = 0.001). The median time between palliative care consultation and death was 3 days (IQR = 2-22). A total of 63% (37/58) of patients who were discharged from the hospital died during follow-up. The median follow-up time was 55 days (95% CI = 26.9-83.0). The overall mortality rate for the entire group during hospitalization and after hospital discharge was 80.8% (80/99). CONCLUSION: Fewer than 3 out of 10 hospitalized cancer patients requiring admission to the ICU were evaluated by the palliative care team despite having incurable cancer. The qSOFA score of patients at the time of the ICU consultation was the only risk factor for mortality during hospitalization. Future research efforts in Mexico should focus on earlier integration of palliation care with usual oncology care in incurable cancer patients.

RESUMO

BACKGROUND: As of June 15, 2020, a cumulative total of 7,823,289 confirmed cases of COVID-19 have been reported across 216 countries and territories worldwide. However, there is little information on the clinical characteristics and outcomes of critically ill patients with severe COVID-19 who were admitted to intensive care units (ICUs) in Latin America. The present study evaluated the clinical characteristics and outcomes of critically ill patients with severe COVID-19 who were admitted to ICUs in Mexico. METHODS: This was a multicenter observational study that included 164 critically ill patients with laboratory-confirmed COVID-19 who were admitted to 10 ICUs in Mexico, from April 1 to April 30, 2020. Demographic data, comorbid conditions, clinical presentation, treatment, and outcomes were collected and analyzed. The date of final follow-up was June 4, 2020. RESULTS: A total of 164 patients with severe COVID-19 were included in this study. The mean age of patients was 57.3 years (SD 13.7), 114 (69.5%) were men, and 6.0% were healthcare workers. Comorbid conditions were common in patients with critical COVID-19: 38.4% of patients had hypertension and 32.3% had diabetes. Compared to survivors, nonsurvivors were older and more likely to have diabetes, hypertension or other conditions. Patients presented to the hospital a median of 7 days (IQR 4.5-9) after symptom onset. The most common presenting symptoms were shortness of breath, fever, dry cough, and myalgias. One hundred percent of patients received invasive mechanical ventilation for a median time of 11 days (IQR 6-14). A total of 139 of 164 patients (89.4%) received vasopressors, and 24 patients (14.6%) received renal replacement therapy during hospitalization. Eighty-five (51.8%) patients died at or before 30 days, with a median survival of 25 days. Age (OR, 1.05; 95% CI, 1.02-1.08; p<0.001) and C-reactive protein levels upon ICU admission (1.008; 95% CI, 1.003-1.012; p<0.001) were associated with a higher risk of in-hospital death. ICU length of stay was associated with reduced in-hospital mortality risk (OR, 0.89; 95% CI, 0.84-0.94; p<0.001). CONCLUSIONS: This observational study of critically ill patients with laboratory-confirmed COVID-19 who were admitted to the ICU in Mexico demonstrated that age and C-reactive protein level upon ICU admission were associated with in-hospital mortality, and the overall hospital mortality rate was high.

RESUMO

Decoration of matrices such as silicates, graphene, etc. is an efficient technique in order to develop multifunctional materials with enhanced properties, which are of use for microbial control. Consequently, it leads to an increased search for alternative matrices and synthesis methods for decoration. Herein, decoration of a fumed silica is proposed, with structures that consisted of silver (Ag@FS), copper hydroxy salt (CuHS@FS), and copper (Cu@FS), for antibacterial applications. With the simple combination of the metal precursor salt, the appropriate solvent, and the fumed silica, the composites were obtained by one-pot solvothermal (200 °C for 1 h), rapid (2 min) microwave assisted precipitation, and by ascorbic acid chemical reduction, respectively. Characterization by powder X-ray diffraction (XRD), thermogravimetric analysis (TGA), and field emission scanning electron microscopy (FE-SEM) proved the successful decoration of the fumed silica with layered copper hydroxy salt (90 width x 970 length nm) and round-like metallic Ag (210 nm) and Cu (370 nm) particles. Fourier transformed infrared (FTIR) and Raman spectroscopy evidenced the presence of SiOMetal interactions. The antibacterial activity was evaluated against the Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, giving inhibition and bactericidal values between 3-12 mg/ mL and 12-24 mg/ mL, respectively, with a maximum ion liberation ratio of 1.4 %. The application of the fumed silica presented here, is an attractive alternative to existing matrices, in order to fabricate multifunctional materials, as it is ready-to-use and feasible for large-scale production. Moreover, the applied synthesis routes provide rapid approaches for decoration, creating composites useful for antibacterial applications.

RESUMO

BACKGROUND: Polyphenol-rich olive extracts are non-toxic and have anti-inflammatory, neuroprotective and antiadipogenic effects in cell and animal models. OBJECTIVE: To evaluate the potential influence of olive extracts on the mechanisms of digestion and absorption of polysaccharides and fats by quantifying amylase, glucose, phospholipase, and cholesterol in the medaka fish model. MATERIAL AND METHODS: For each assay, six adult fish were placed in a tank with an extract (0.01% concentration), performing three replicates per extract. A control group with standard feeding was used. The same procedure was followed to study glucose, adding a polysaccharide-rich diet and a corresponding overfed control. The fish were maintained under these conditions for five days. Five olive extracts were used without attempting to purify the polyphenols due to possible synergistic effects. Total concentrations were between 2-116mg/g (mainly oleuropein and hydroxytyrosol). On completion, amylase, phospholipase A2, glucose and cholesterol were quantified in each group. All assays were conducted in triplicate. Enzyme activities were also studied in juveniles. Non-parametric tests were used to determine possible differences, considering p < 0.05 to denote statistical significance. RESULTS: Polyphenol extracts were not toxic at a concentration of 0.1%, ten times higher than the concentration used. An overall decrease in glucose levels was observed in fish overfed with carbohydrates with the addition of the extracts, but without returning to the levels in the control group with standard feeding (between 15-40% decrease). There was no impact on amylase in adults or juveniles, an overall but not significant decrease in cholesterol, and an overall increase in phospholipase in the juveniles. CONCLUSION: Olive extracts rich in polyphenols lower glucose levels in overfed fish


ANTECEDENTES: Los extractos de aceitunas ricos en polifenoles no son tóxicos y tienen efectos antiinflamatorios, neuroprotectores y antiadipogénicos en modelos celulares y animales. OBJETIVO: Evaluar la influencia potencial de los extractos de aceituna en los mecanismos de digestión y absorción de polisacáridos y grasas mediante la cuantificación de amilasa, glucosa, fosfolipasa y colesterol en el modelo de pez medaka. MATERIAL Y MÉTODOS: Para cada ensayo, se colocaron seis peces adultos en un tanque con un extracto (al 0,01%), realizando tres repeticiones por extracto. Se usó un grupo control con alimentación estándar. Se siguió el mismo procedimiento para estudiar la glucosa, agregando una dieta rica en polisacáridos y un control de sobrealimentados. Los peces se mantuvieron en estas condiciones durante cinco días. Se usaron cinco extractos del olivo sin intentar purificar los polifenoles debido a posibles efectos sinérgicos. Las concentraciones totales fueron entre 2-116 mg/g (principalmente oleuropeína e hidroxitirosol). Al finalizar, se cuantificaron amilasa, fosfolipasa A2, glucosa y colesterol en cada grupo. Todos los ensayos se realizaron por triplicado. Las actividades enzimáticas también se estudiaron en alevines. Se utilizaron pruebas no paramétricas para determinar posibles diferencias, considerando p <0.05 para significación estadística. RESULTADOS: Los extractos de polifenoles no fueron tóxicos a una concentración de 0.1%, diez veces mayor que la concentración utilizada. Se observó una disminución general en los niveles de glucosa en peces sobrealimentados con carbohidratos con la adición de extractos, pero sin volver a los niveles del grupo control con alimentación estándar (disminución entre 15-40%). No hubo impacto sobre la amilasa en adultos o juveniles, se observó una disminución general pero no significativa del colesterol y un aumento general de la fosfolipasa en los juveniles. CONCLUSIÓN: Los extractos de aceitunas ricos en polifenoles reducen los niveles de glucosa en peces sobrealimentados

RESUMO

OBJECTIVE: To analyze the situation, evaluation and proposals for improvement of the Preventive Activities and Health Promotion Program (PAPPS). MATERIAL AND METHODS: A qualitative study of situation analysis was carried out for the evaluation of the PAPPS in 2 phases: 1) Generation of ideas and collection of information through a DAFO matrix, using 2 types of criteria: internal (strengths and weaknesses), and external (threats and opportunities); 2) Prioritization of the improvement proposals collected. Selection of participants: Key informants were identified taking into account their relationship and knowledge of the PAPPS program. All members of the PAPPS, expert groups and members with past participation were included, as well as the coordinators, including the autonomous leaders of the PAPPS. Two invitations to participate in the study were sent: the first from December 29, 2017 to February 11, 2018, and the second from January 10 to 23, 2019. The information was obtained from a questionnaire designed to be self-completed. RESULTS AND CONCLUSIONS: A total of 73 subjects answered the questionnaire. 35% of the participants were members of the PAPPS working groups, followed by family doctors from other areas, with 20.5%. The order of prioritization of the improvement proposals was as follows: 1) Unify recommendations with other semFYC working groups; 2) Prepare lists with "Recommendations not to do" from the point of view of prevention; 3) Incorporate PAPPS in the political agenda; 4) Greater coordination and interaction between groups with common competences; 5) Teaching in undergraduate and teaching units; 6) Review, update and dissemination of the program in Primary Care.

RESUMO

OBJECTIVES: Studying the psychosocial sphere of patients who undergo any treatment allows to have more information about its repercussion and can help the choice of an appropriate and personalized treatment. Due to the absence of specific instruments at present, the objective is to design and validate a health questionnaire regarding the treatment received with ESWL. METHODS: It was carried out in 6 phases using a sampleof 50 patients treated with ESWL in 2015 in ourcenter, whom we interviewed by telephone. In phase1 the items were proposed based on bibliographic review,in phase 2 those that scored below 7 were eliminatedaccording to the evaluation from 0 to 10 on theitems made by specialists. In phase 3, values of 1 to 5were assigned to each item and those with correctedcorrelation more than 0.2 and not significant (p>0.05)discriminant power with U-Mann Whitney were eliminated.In phase 4 the reliability of the questionnaire waschecked with two indexes (Cronbach's alpha and twoGuttman's halves). In phase 5, the factor analysis withVarimax rotation was performed to calculate the constructvalidity and in stage 6, the scores were analyzedto establish reference values. RESULTS: 50 patients (32 men, 18 women). Medianage 59 years (27-79). In phase 1, 35 items were proposed,9 of which were eliminated in phase 2. The initialquestionnaire with 26 items was distributed, with 18being eliminated in phase 3. The final questionnaire wasformed with 8 items. In phase 4 the results of Cronbach'salpha and Guttman's two halves index were 0.44 and0.323 respectively. In phase 5 after factor analysis, wefound 4 factors with 2 items each (background, impactof the acute picture, post-treatment, quality of life) able toexplain 71.19% of the variance. The median scores ofthe scale, extreme values and quartiles studied in phase6 were respectively: P50: 17 (minimum-maximum 9-25),P25: 14 and P75: 20. CONCLUSIONS: The study carried out has provided anew instrument for assessing satisfaction after treatmentwith ESWL with adequate reliability and validity values.Future studies will be necessary to contrast its true clinicalusefulness.

RESUMO

AIM: To estimate the prevalence of alcohol consumption and analyse the drinking patterns among primary healthcare (PHC) providers. DESIGN: Observational, cross-sectional, descriptive study. SETTING: PHC centres in the Spanish National Health System (SNHS). PARTICIPANTS: Doctors and nurses who completed an online questionnaire which explored their alcohol intake, using the Alcohol Use Disorders Identification Test (AUDIT-C) alcohol assessment tool. The study population was recruited by random sampling stratified by regions of the SNHS PHC centres. PRIMARY AND SECONDARY OUTCOME MEASURES: Frequency of alcohol consumption, number of alcohol drinks on a typical day, frequency of more than six standard drinks (SDs) intake. RESULTS: A total of 1760 PHC providers completed the questionnaire. The frequency of alcohol consumption was: abstention (12%, 95% CI 10.4% to 13.5%); one or less SDs/month (26%, 95% CI 23.8% to 27.9%); 2-4 SDs/month (32.2%, 95% CI 29.7% to 34.1%); 2-3 SDs/week (17.9%, 95% CI 16.0% to 19.6%); four or more SDs/week (11.9%, 95% CI 10.3% to 13.3%). The number of drinks on a typical day was: none (45.6%, 95% CI 42.9% to 47.6%); 1-2 drinks (47.3%, 95% CI 23.8% to 27.9%); 3-4 drinks (6.5%, 95% CI 5.3% to 7.6%). The percentage of hazardous drinking, according to AUDIT-C criteria, was 32% (95% CI 26.7 to 37.3), with a greater frequency of intake in older professionals (p<0.001), in contrast to a higher number of drinks consumed on a typical day by younger providers (p<0.001). Intake was higher among males (p<0.001), primary care physicians (p<0.001) and resident trainers (p<0.001). CONCLUSIONS: Our study discloses the most up-to-date portrait of current alcohol consumption among Spanish PHC providers, showing a higher prevalence of alcohol intake, compared with the general population. Preventive strategies should be implemented to improve the awareness and training of PHC professionals towards alcohol consumption.

RESUMO

Objective: The aim of this study was to estimate the incidence of delirium and its risk factors among critically ill cancer patients in an intensive care unit (ICU). Materials and Methods: This is a prospective cohort study. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) was measured daily at morning to diagnose delirium by a physician. Delirium was diagnosed when the daily was positive during a patient's ICU stay. All patients were followed until they were discharged from the ICU. Using logistic regression, we estimated potential risk factors for developing delirium. The primary outcome was the development of ICU delirium. Results: There were 109 patients included in the study. Patients had a mean age of 48.6 ± 18.07 years, and the main reason for admission to the ICU was septic shock (40.4%). The incidence of delirium was 22.9%. The mortality among all subjects was 15.6%; the mortality rate in patients who developed delirium was 12%. The only variable that had an association with the development of delirium in the ICU was the days of use of mechanical ventilation (OR: 1.06; CI 95%: 0.99-1.13;p=0.07). Conclusion: Delirium is a frequent condition in critically ill cancer patients admitted to the ICU. The duration in days of mechanical ventilation is potential risk factors for developing delirium during an ICU stay. Delirium was not associated with a higher rate of mortality in this group of patients.
