RESUMO

Background: Though the Spanish version of the Coping Strategies Inventory (CSI) is frequently used, it has not been subjected to any significant re-evaluation from a psychometric perspective. Method: We analysed CSI data that was focused on an academic stress situation, using a university sample of 874 participants, 50% of each gender. We conducted reliability, confirmatory factor, and factorial invariance across gender analyses. Results: The first-order factorial structure was confirmed, showing an adequate fit for the eight-factor coping strategies model with good reliability indices. Neither the second-order (problem-centred vs. emotion-centred) nor third-order (engagement vs. disengagement) strategies showed an adequate fit. Factorial invariance for gender was confirmed. Conclusions: The theoretical and applied implications of the results are discussed.(AU)


Antecedentes: Aunque la versión española del del Inventario de Estrategias de Afrontamiento (CSI) se usa frecuentemente, no se ha sometido a reevaluación psicométrica. Método: Analizamos datos del CSI aplicados a situaciones de estrés académico utilizando una muestra universitaria de 874 participantes, 50% de cada género. Llevamos a cabo análisis de fiabilidad, confirmatorios y de invarianza factorial por género. Resultados: Se confirmó la estructura factorial de primer orden, mostrando un ajuste adecuado el modelo de 8 estrategias de afrontamiento, con buenos índices de fiabilidad. No mostraron un ajuste adecuado las factorizaciones de segundo orden (centrado en el problema o en la emoción) ni de tercer orden (compromiso o retirada). Se confirmó la invarianza factorial por género. Conclusiones: Se discuten las implicaciones teóricas y aplicadas de los resultados.(AU)

RESUMO

Objetivo Caracterizar la dispensa de antibióticos a pacientes ambulatorios en un instituto de seguridad social universitario durante el año 2020. Método Se realizó un estudio observacional, descriptivo-correlacional de utilización de medicamentos. Para cuantificar la dispensa, se utilizó la dosis diaria definida (DDD) por 1 000 habitantes por día (DHD) y la unidad de dosis, recomendadas por la Organización Mundial de la Salud (OMS), y el valor intrínseco terapéutico potencial como indicador cualitativo, según Laporte y Tognoni. Resultados Se incluyeron 4 748 dispensaciones ambulatorias. Edad promedio: 42 años; rango: 0-94 años, con predominio del sexo femenino (55%). La mayoría pertenecían al grupo de las penicilinas (51,3%) con predominio de amoxicilina en asociaciones a dosis fija o como monofármaco (48,3%), seguida por los macrólidos (21,0%) y las fluoroquinolonas (17,0%). Se pudo apreciar un consumo potencial de 7,7 DHD, lo cual implica que, en promedio, 7 de cada 1 000 afiliados de la institución estuvo expuesto a estos agentes diariamente, con predominio de amoxicilina asociada a ácido clavulánico (2,2 DHD). Conclusión La población general de universitarios estuvo expuesta a una prescripción alta de amoxicilina en asociaciones a dosis fijas, algunas de valor inaceptable o relativa, así como también a los nuevos macrólidos y fluoroquinolonas de segunda y tercera generación. Esto requiere especial atención, porque el consumo indiscriminado a nivel ambulatorio de antibióticos de amplio espectro podría convertirse en un factor de riesgo para el desarrollo de resistencia bacteriana; implica, además, un riesgo en la aparición de eventos adversos serios y un incremento en el gasto sanitario.


Objective To characterize the dispensing of antibiotics to outpatients of a university social security institute during the year 2020. Methods An observational, descriptive-correlational study of drug use was carried out. To quantify the dispensation, the defined daily dose (DDD) per 1 000 inhabitants per day (DHD) and the dose unit, recommended by the World Health Organization (WHO), were used. The classification of potential therapeutic intrinsic value, by Laporte and Tognoni, was used as a qualitative indicator. Results A total of 4 748 outpatient dispensations of antibiotics were included, 55% for the female sex. Average age: 42 years; range: 0-94 years. The majority belonged to the penicillin group (51.3%) with a predominance of amoxicillin (48.3%) in fixed-dose associations or mono-drug, followed by macrolides (21.0%) and fluoroquinolones (17.0%). A potential consumption of 7.7 DHD was observed, which implies that, on average, 7 out of every 1 000 members of the institution were exposed to these agents daily with a predominance of amoxicillin associated with clavulanic acid (2.2 DHD). Conclusion The general population of university students was exposed to high fixed-dose associations prescription of amoxicillin, some of relative or unacceptable potential therapeutic intrinsic value, as well as to the new macrolides and second or third generation of fluoroquinolones. This requires special attention because the indiscriminate outpatient use of broad-spectrum antibiotics could become a risk factor for the development of bacterial resistance. It also implies a higher risk of serious adverse events and an increase in healthcare costs.

RESUMO

Use of interleukin (IL-6) inhibitors has become one of the most complicated clinical issues in treating coronavirus disease 2019 (COVID-19). Recently, randomized open-label platform trials have found that IL-6 inhibitors have a beneficial effect on mortality in severe COVID-19. However, several questions arise around their mechanism of action in this disease, as well as how, when, and at which dose they should be used. IL-6 has both proinflammatory and anti-inflammatory effects, which may modulate the course of COVID-19, whose immunopathogenesis is driven by the innate immune system, autoantibodies, and interferon. Given that patients with delayed seroconversion against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein would be at the highest risk of complications beyond the second week of disease, we propose that considering patient serostatus at admission could optimize the use of IL-6 inhibitors in COVID-19. We predict that the net treatment benefits could be higher in the subgroup of patients with delayed seroconversion as compared to those who seroconvert more rapidly after SARS-CoV-2 infection.

RESUMO

Optimizing the well-being of the oncology clinician has never been more important. Well-being is a critical priority for the cancer organization because burnout adversely impacts the quality of care, patient satisfaction, the workforce, and overall practice success. To date, 45% of U.S. ASCO member medical oncologists report experiencing burnout symptoms of emotional exhaustion and depersonalization. As the COVID-19 pandemic remains widespread with periods of outbreaks, recovery, and response with substantial personal and professional consequences for the clinician, it is imperative that the oncologist, team, and organization gain direct access to resources addressing burnout. In response, the Clinician Well-Being Task Force was created to improve the quality, safety, and value of cancer care by enhancing oncology clinician well-being and practice sustainability. Well-being is an integrative concept that characterizes quality of life and encompasses an individual's work- and personal health-related environmental, organizational, and psychosocial factors. These resources can be useful for the cancer organization to develop a well-being blueprint: a detailed start plan with recognized strategies and interventions targeting all oncology stakeholders to support a culture of community in oncology.

RESUMO

BACKGROUND: Black-foot and Petri diseases are the main fungal diseases associated with young grapevine decline. Two field experiments were established to evaluate the preventive effect of two potential biocontrol agents (BCAs), that is Streptomyces sp. E1 + R4 and Pythium oligandrum Po37, and three BCA-commercial products containing Trichoderma atroviride SC1, Trichoderma koningii TK7 and Pseudomonas fluorescens + Bacillus atrophaeus on fungal infection in grafted plants and plant growth parameters. RESULTS: The effectiveness of some BCA in reducing the incidence and severity of both diseases was dependent on the plant part analyzed and the plant age. No single BCA application was able to control both diseases. Streptomyces sp. E1 + R4 were able to reduce significantly the infection of the most prevalent black-foot disease fungi while P. oligandrum Po37 and Trichoderma spp. were able to reduce significantly Phaeomoniella chlamydospora and Phaeoacremonium minimum (Petri disease) infection. BCA treatments had no effect on the shoot weight, and root weight was significantly lower in all BCA treatments with respect to the control. CONCLUSIONS: The combination of the disease-suppressive activity of two or more beneficial microbes in a biocontrol preparation is required to prevent infection by black-foot and Petri disease fungi in vineyards.

RESUMO

Phytopathogenic fungi responsible for post-harvest diseases on fruit and vegetables cause important economic losses. We have previously reported that harmol (1-methyl-9H-pyrido[3,4-b]indol-7-ol) is active against the causal agents of green and gray molds Penicillium digitatum and Botrytis cinerea, respectively. Here, antifungal activity of harmol was characterized in terms of pH dependency and conidial targets; also photodynamic effects of UVA irradiation on the antimicrobial action were evaluated. Harmol was able to inhibit the growth of both post-harvest fungal disease agents only in acidic conditions (pH 5), when it was found in its protonated form. Conidia treated with harmol exhibited membrane integrity loss, cell wall disruption, and cytoplasm disorganization. All these deleterious effects were more evident for B. cinerea in comparison to P. digitatum. When conidial suspensions were irradiated with UVA in the presence of harmol, antimicrobial activity against both pathogens was enhanced, compared to non-irradiated conditions. B. cinerea exhibited a high intracellular production of reactive oxygen species (ROS) when was incubated with harmol in irradiated and non-irradiated treatments. P. digitatum showed a significant increase in ROS accumulation only when treated with photoexcited harmol. The present work contributes to unravel the antifungal activity of harmol and its photoexcited counterpart against phytopathogenic conidia, focusing on ROS accumulation which could account for damage on different cellular targets.

RESUMO

Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and/or pulmonary embolism (PE). Many surgeons and clinicians believe that VTE after coronary artery bypass grafting (CABG) has little clinical significance because it is seldom diagnosed. This study aimed to identify VTE after CABG, independent of clinical suspicion. In this prospective, observational, single-center study, 100 patients underwent computed tomographic pulmonary angiography (multidetector-64) and lower extremity venous compressive ultrasound after elective CABG. Patients with high risk for VTE were excluded. Aspirin was maintained throughout the preoperative and postoperative periods, and early ambulation was encouraged. Postoperatively, no mechanical or heparin prophylaxis was used in any patients. At the discretion of the surgeons, 83 surgeries were on-pump, and 17 were off-pump. On average, tomography and ultrasound were performed 7 ± 3 days after CABG. Isolated PE was observed in 13 of 100 patients (13%), simultaneous PE and DVT in 8 of 100 (8%), and isolated DVT in 4 of 100 (4%), thus totaling 25/100 VTEs (25%). Of the 21 PEs, 3 of 21 (14%) involved subsegmental, 15 of 21 (71%) segmental, 1 of 21 (5%) lobar, and 2 of 21 (10%) central pulmonary arteries. Of the 12 DVTs, all were distal (below the popliteal vein), and 2 of 12 (17%) were also proximal; 5 of 12 (42%) were unilateral, of which 3 of 5 (60%) on the contralateral saphenous vein-harvested leg. No VTE caused hemodynamic instability, and none was clinically suspected. In conclusion, VTEs were frequent, some extensive proximal VTEs occurred, but most were distally localized. Many patients in this series would have been discharged without diagnosis of and treatment for PE and/or DVT.

RESUMO

Anaplastic transformation of well-differentiated thyroid carcinomas at distant metastatic sites is a rare condition. Most cases described in the literature have occurred in the thyroid or regional lymph nodes. We report a case of anaplastic transformation of the follicular variant of papillary thyroid carcinoma in mandibular metastases. A 76-year-old female presented with a painful and enlarging mandibular mass. She had been treated in the past for the follicular variant of papillary thyroid carcinoma. A palliative hemi-mandibulectomy was performed. Histology revealed a metastatic papillary thyroid carcinoma, follicular variant, with an unusual finding of solid pleomorphic epithelioid and spindle cell areas, consistent with anaplastic transformation.

RESUMO

Objetivo Determinar la seroprevalencia de anticuerpos a virus de sarampión, rubeola, parotiditis, hepatitis B y los tres serotipos de poliovirus en población infantil del Departamento del Quindío, Colombia. Métodos Se colectaron muestras de sangre de 170 niños en edades comprendidas entre los cinco y nueve años de nueve departamentos del Quindío. Se determinó la presencia de anticuerpos tipo IgG para sarampión, rubeola y parotiditis mediante un ELISA indirecto comercial. La inmunidad contra la poliomielitis se determinó por la presencia de anticuerpos neutralizantes a poliovirus según los métodos recomendados por OMS. Resultados De los 170 niños estudiados, 169 (99,41 %), 170 (100 %), and 167 (98,2 %) fueron seropositivos a poliovirus 1, poliovirus 2, y poliovirus 3, respectivamente. El título promedio geométrico de anticuerpos fue 178 para poliovirus tipo 1, 120 para el tipo 2 y 56 para el tipo 3. De los 170 niños, el 96,47 % estuvo protegido contra parotiditis y rubeola y el 86,47 % contra sarampión. Se demostró respuesta serológica positiva contra el virus de la hepatitis B solamente en el 62,35 % de las muestras. Conclusiones El programa de inmunización en el Quindío permitió la seroprotección contra los tres serotipos de la polio, rubeola y parotiditis. Sin embargo, la población infantil no está completamente protegida contra la infección con sarampión y virus de la hepatitis B.(AU)


Objective The main goal of this research was to assess the seroprevalence of antibodies against measles, rubella, mumps, hepatitis B and all three poliovirus serotypes among children in the Quindío Department, Colombia. Methods Blood samples were obtained from 170 healthy children aged 5-9 years from nine municipalities in Quindío. The presence of serum IgG antibodies against measles, rubella, mumps and Hepatitis B were determined using commercial indirect ELISA kits. Immunity to poliomyelitis was assessed through the presence of neutralizing antibodies following the method recommended by the World Health Organization. Results Among the 170 children enrolled, 169 (99.41%), 170 (100 %), and 167 (98.2 %) were seropositive to poliovirus 1, poliovirus 2, and poliovirus 3, respectively. The average reciprocal antibody titers were 178 for poliovirus type 1, 120 for type 2 and 56 for type 3. Of the 170 children, 96.47 % were protected against mumps and rubella, and 86.47 % against measles. Only 106 (62.35 %) of the studied subjects were proved to be seropositive to hepatitis B. Conclusion The immunization program in Quindío has provided seroprotection against all three poliomyelitis serotypes, rubella and mumps. However, the child population is not fully protected against measles and hepatitis B virus infections.(AU)

RESUMO

BACKGROUND: The value of community-based cancer research has long been recognized. In addition to the National Cancer Institute's Community Clinical and Minority-Based Oncology Programs established in 1983, and 1991 respectively, the National Cancer Institute established the National Cancer Institute Community Cancer Centers Program in 2007 with an aim of enhancing access to high-quality cancer care and clinical research in the community setting where most cancer patients receive their treatment. This article discusses strategies utilized by the National Cancer Institute Community Cancer Centers Program to build research capacity and create a more entrenched culture of research at the community hospitals participating in the program over a 7-year period. METHODS: To facilitate development of a research culture at the community hospitals, the National Cancer Institute Community Cancer Centers Program required leadership or chief executive officer engagement; utilized a collaborative learning structure where best practices, successes, and challenges could be shared; promoted site-to-site mentoring to foster faster learning within and between sites; required research program assessments that spanned clinical trial portfolio, accrual barriers, and outreach; increased identification and use of metrics; and, finally, encouraged research team engagement across hospital departments (navigation, multidisciplinary care, pathology, and disparities) to replace the traditionally siloed approach to clinical trials. LIMITATIONS: The health-care environment is rapidly changing while complexity in research increases. Successful research efforts are impacted by numerous factors (e.g. institutional review board reviews, physician interest, and trial availability). The National Cancer Institute Community Cancer Centers Program sites, as program participants, had access to the required resources and support to develop and implement the strategies described. Metrics are an important component yet often challenging to identify and collect. The model requires a strong emphasis on outreach that challenges hospitals to improve and expand their reach, particularly into underrepresented populations and catchment areas. These efforts build on trust and a referral pipeline within the community which take time and significant commitment to establish. CONCLUSION: The National Cancer Institute Community Cancer Centers Program experience provides a relevant model to broadly address creating a culture of research in community hospitals that are increasingly networked via systems and consortiums. The strategies used align well with the National Cancer Institute-American Society of Clinical Oncology Accrual Symposium recommendations for patient-/community-, physician-/provider-, and site-/organizational-level approaches to clinical trials; they helped sites achieve organizational culture shifts that enhanced their cancer research programs. The National Cancer Institute Community Cancer Centers Program hospitals reported that the strategies were challenging to implement yet proved valuable as they provided useful metrics for programmatic assessment, planning, reporting, and growth. While focused on oncology trials, these concepts may be useful within other disease-focused research as well.

RESUMO

PURPOSE: Screening logs have the potential to help oncology clinical trial programs at the site level, as well as trial leaders, address enrollment in real time. Such an approach could be especially helpful in improving representation of racial/ethnic minority and other underrepresented populations in clinical trials. METHODS: The National Cancer Institute Community Cancer Centers Program (NCCCP) developed a screening log. Log data collected from March 2009 through May 2012 were analyzed for number of patients screened versus enrolled, including for demographic subgroups; screening methods; and enrollment barriers, including reasons for ineligibility and provider and patient reasons for declining to offer or participate in a trial. User feedback was obtained to better understand perceptions of log utility. RESULTS: Of 4,483 patients screened, 18.4% enrolled onto NCCCP log trials. Reasons for nonenrollment were ineligibility (51.6%), patient declined (25.8%), physician declined (15.6%), urgent need for treatment (6.6%), and trial suspension (0.4%). Major reasons for patients declining were no desire to participate in trials (43.2%) and preference for standard of care (39%). Major reasons for physicians declining to offer trials were preference for standard of care (53%) and concerns about tolerability (29.3%). Enrollment rates onto log trials did not differ between white and black (P = .15) or between Hispanic and non-Hispanic patients (P = .73). Other races had lower enrollment rates than whites and blacks. Sites valued the ready access to log data on enrollment barriers, with some sites changing practices to address those barriers. CONCLUSION: Use of screening logs to document enrollment barriers at the local level can facilitate development of strategies to enhance clinical trial accrual.

RESUMO

PURPOSE: The National Cancer Institute (NCI) Community Cancer Centers Program (NCCCP) formed an Early-Phase Working Group to facilitate site participation in early-phase (EP) trials. The Working Group conducted a baseline assessment (BA) to describe the sites' EP trial infrastructure and its association with accrual. METHODS: EP accrual and infrastructure data for the sites were obtained for July 2010-June 2011 and 2010, respectively. Sites with EP accrual rates at or above the median were considered high-accruing sites. Analyses were performed to identify site characteristics associated with higher accrual onto EP trials. RESULTS: Twenty-seven of the 30 NCCCP sites participated. The median number of EP trials open per site over the course of July 2010-June 2011 was 19. Median EP accrual per site was 14 patients in 1 year. Approximately half of the EP trials were Cooperative Group; most were phase II. Except for having a higher number of EP trials open (P = .04), high-accruing sites (n = 14) did not differ significantly from low-accruing sites (n = 13) in terms of any single site characteristic. High-accruing sites did have shorter institutional review board (IRB) turnaround time by 20 days, and were almost three times as likely to be a lead Community Clinical Oncology Program site (small sample size may have prevented statistical significance). Most sites had at least basic EP trial infrastructure. CONCLUSION: Community cancer centers are capable of conducting EP trials. Infrastructure and collaborations are critical components of success. This assessment provides useful information for implementing EP trials in the community.

RESUMO

Multiple myeloma (MM) is a plasma cell neoplasm involving the bone marrow with organ damage and/or a monoclonal protein (M-spike in the serum and/or urine). This neoplasm typically affects adults over the age of 50. Acute lymphoblastic leukemia (ALL) is a hematological disorder involving at least 20% lymphoblasts in the bone marrow of the B-cell lineage. Acute lymphoblastic leukemia most commonly affects young children with 75% of cases occurring in children less than 6 years old. This case report describes a patient diagnosed with MM in 2000 who achieved a complete remission in 2006 after chemotherapy. Four years later, the patient presented with sudden pancytopenia. A bone marrow biopsy was obtained revealing a B lymphoblastic leukemia in an extensively fibrotic marrow without evidence of MM. A diagnosis of ALL with myelofibrosis is rare in the adult population, acute myelofibrosis (AMF) is more commonly associated with myeloproliferative disorders, and the development of acute leukemia in myeloma is rare. To the best of our knowledge, the presence of MM, ALL, and myelofibrosis in one patient has never been reported.

RESUMO

BACKGROUND: Although the occurrence of intraoperative cardiac arrest is rare, it is a severe adverse event with a high mortality rate. Trauma patients have additional causes for intraoperative arrest, and we hypothesised that the survival of trauma patients who experienced intraoperative cardiac arrest would be worse than nontrauma patients who experienced intraoperative cardiac arrest. OBJECTIVES: The aim of the present study was to compare the outcomes of trauma and nontrauma patients after intraoperative cardiac arrest. METHODS: In a tertiary university hospital and trauma centre, the intraoperative cardiac arrest cases were evaluated from January 2007 to December 2009, excluding patients submitted to cardiac surgery. Data were prospectively collected using the Utstein-style. Outcomes among the patients with trauma were compared to the patients without trauma. RESULTS: We collected data from 81 consecutive intraoperative cardiac arrest cases: 32 with trauma and 49 without trauma. Patients in the trauma group were younger than the patients in the nontrauma group (44±23 vs. 63±17, p<0.001). Hypovolaemia (63% vs. 35%, p=0.022) and metabolic/hydroelectrolytic disturbances (41% vs. 2%, p<0.001) were more likely to cause the cardiac arrest in the trauma group. The first documented arrest rhythm did not differ between the groups, and pulseless electrical activity was the most prevalent rhythm (66% vs. 53%, p=0.698). The return of spontaneous circulation (47% vs. 63%, p=0.146) and survival to discharge with favourable neurological outcome (16% vs. 14%, p=0.869) did not differ between the two groups. CONCLUSIONS: The outcomes did not differ between patients with trauma and nontrauma intraoperative cardiac arrest.

RESUMO

To reduce toxicity/treatment time and improve accuracy, intraoperative electron radiotherapy (IOERT) was used as an alternative to electron beam radiation therapy boost. Primary objective was to determine feasibility and acute toxicity. From August 2009 to June 2011, 50 patients (age 32 to 76 years) with in situ or invasive breast cancer (Stage 0 to IIIA) were treated. Toxicity assessed according to standard National Cancer Institute scales. Median tumor size was 20 mm (range, 6 to 80 mm) with 43 infiltrating ductal, two infiltrating lobular, and five ductal in situ carcinoma. A single 10-Gy fraction boost was given to the tumor bed after resection followed by whole-breast radiotherapy. After IOERT, three patients required completion axillary lymph node dissection, eight had reexcision resulting from positive margins, and four opted for completion mastectomy. The median follow-up was 10 months (range, 2 to 24 months). Ten patients had Grade 1 and one reported Grade 2 breast pain 2 weeks after IOERT; all resolved at 6 weeks. Two patients had delay in wound healing, but none developed a wound infection. Three patients reported symptomatic fat necrosis. No other toxicities were reported. IOERT resulted in a reduction in treatment time, was not associated with additional toxicity or change in the acute toxicity profile, and is a feasible treatment option in a community hospital setting.

RESUMO

OBJECTIVES AND METHODS: The recommended method for the measurement of radiochemical purity (RCP) of ¹¹¹In-labelled pentetreotide is thin-layer chromatography with a silica gel as the stationary phase and a 0.1 N sodium citrate solution (pH 5) as the mobile phase. According to the supplier's instructions, the mobile phase must be prepared before the test is carried out, and the recommended stationary phase is off-market. We propose a new method for RCP measurement in which the mobile phase is acid citrate dextrose, solution A, which does not need to be prepared beforehand, and thin-layer chromatography is performed with a silica gel-impregnated glass fibre sheet as the stationary phase. We used both methods to measure the percentages of radiopharmaceutical and impurities. RESULTS: The range of RCP values obtained was 98.0-99.9% (mean=99.3%) by the standard method and 98.1-99.9% (mean=99.2%) by the new method. We observed no differences between the RCP values of both methods (P=0.070). CONCLUSION: The proposed method is suitable for RCP testing because it yields results that are in good agreement with those of the standard method and because it is easier to perform as the mobile-phase solution need not be prepared in advance.
