RESUMO

BACKGROUND: This study will pilot-test an innovative just-in-time adaptive intervention to reduce severe respiratory illness among children with severe cerebral palsy (CP). Our intervention program, Respiratory Exacerbation-Plans for Action and Care Transitions (RE-PACT), delivers timely customized action planning and rapid clinical response when hospitalization risk is elevated. OBJECTIVE: This study aims to establish RE-PACT's feasibility, acceptability, and fidelity in up to 90 children with severe CP. An additional aim is to preliminarily estimate RE-PACT's effect size. METHODS: The study will recruit up to 90 caregivers of children with severe CP aged 0 to 17 years who are cared for by a respiratory specialist or are receiving daily respiratory treatments. Participants will be recruited from pediatric complex care programs at the University of Wisconsin-Madison (UW) and the University of California, Los Angeles (UCLA). Study participants will be randomly assigned to receive usual care through the complex care clinical program at UW or UCLA or the study intervention, RE-PACT. The intervention involves action planning, rapid clinical response to prevent and manage respiratory illness, and weekly SMS text messaging surveillance of caregiver confidence for their child to avoid hospitalization. RE-PACT will be run through 3 successively larger 6-month trial waves, allowing ongoing protocol refinement according to prespecified definitions of success for measures of feasibility, acceptability, and fidelity. The feasibility measures include recruitment and intervention time. The acceptability measures include recruitment and completion rates as well as intervention satisfaction. The fidelity measures include observed versus expected rates of intervention and data collection activities. The primary clinical outcome is a severe respiratory illness, defined as a respiratory diagnosis requiring hospitalization. The secondary clinical outcomes include hospital days and emergency department visits, systemic steroid courses, systemic antibiotic courses, and death from severe respiratory illness. RESULTS: The recruitment of the first wave began on April 27, 2022. To date, we have enrolled 30 (33%) out of 90 participants, as projected. The final wave of recruitment will end by October 31, 2023, and the final participant will complete the study by April 30, 2024. We will start analyzing the complete responses by April 30, 2024, and the publication of results is expected at the end of 2024. CONCLUSIONS: This pilot intervention, using adaptive just-in-time strategies, represents a novel approach to reducing the incidence of significant respiratory illness for children with severe CP. This protocol may be helpful to other researchers and health care providers caring for patients at high risk for acute severe illness exacerbations.

RESUMO

La granulomatosis con poliangeítis es una vasculitis sistémica, necrosante y granulomatosa que afecta el tracto respiratorio superior e inferior y los riñones. Se presenta el caso de una paciente blanca, de 59 años de edad, hipertensa y fumadora inveterada, que ingresó por presentar síntomas constitucionales, orinas turbias y hemáticas, así como creatininemia elevada con valor previo normal. Con impresión diagnóstica inicial de infección del tracto urinario se indica antibioticoterapia. Después del tercer día de iniciado el tratamiento, mejoraron los síntomas constitucionales y, de forma progresiva, comenzó con manifestaciones multiorgánicas (renal, respiratoria, cutánea y musculoesquelética) sugestivas de vasculitis sistémica. Como elementos significativos, en exámenes complementarios se detectaron azoados y reactantes de fase aguda aumentados, sedimento urinario activo, imagen nodular en vértice pulmonar derecho y microhemorragias multifocales en ambos campos pulmonares, detectados mediante tomografía computarizada y c-ANCA altamente positivo. Se indicó tratamiento inmunosupresor y citotóxico potente, obteniéndose control inicial de las manifestaciones graves de la enfermedad. Evolutivamente desarrolló complicaciones propias de la entidad y secundarias al tratamiento médico, que la hicieron tributaria de terapia de sustitución renal, falleciendo a los dos años de recibir hemodiálisis iterada. El cuadro clínico, unido a los estudios imagenológicos e inmunológicos (c-ANCA), fueron elementos claves para realizar el diagnóstico.


Granulomatosis with polyangiitis is a systemic, necrotizing, granulomatous vasculitis that affects the upper and lower respiratory tract and kidneys. The case of a 59-year-old white female patient, who is hypertensive and inveterate smoker, is presented; she was admitted for presenting constitutional symptoms, turbid and bloody urine, as well as elevated creatininemia with a normal previous value. With the initial diagnostic impression of urinary tract infection, antibiotic therapy was indicated. After the third day of starting treatment the constitutional symptoms improved, and progressively began with multiorgan manifestations (renal, respiratory, skin and musculoskeletal) suggestive of systemic vasculitis. As significant elements, complementary examinations detected increased nitrogen and acute phase reactants, active urinary sediment, nodular image in the right lung apex and multifocal microhemorrhages in both lung fields through computed tomography, and highly positive c-ANCA. Potent immunosuppressive and cytotoxic treatment was indicated, obtaining initial control of severe manifestations of the disease. Evolutionarily she developed complications specific to the entity and secondary to medical treatment which made her subject to renal replacement therapy, dying two years after receiving iterated hemodialysis. The clinical characteristics, together with the imaging and immunological studies (c-ANCA) were key elements to make the diagnosis.

RESUMO

Introduction Social media outlets such as TikTok (TT) and Instagram (IG) have surged as a method to disseminate information. More recently, healthcare professionals have targeted this space as a means to provide medical education and advice. With the ever-growing content on these applications, there is significant variability and quality of material available, which can lead to the dissemination of misinformation. This study aims to evaluate the accuracy and popularity of content on common orthopaedic pathology on TT and IG. Methods Content on TT and IG related to six common orthopaedic conditions - achilles tendon tear, ACL tear, meniscus tear, tennis elbow, rotator cuff tear, and ankle sprains - was evaluated between April and June 2022. The top ten posts for the top two associated hashtags for each condition were reviewed. The quality of each post was analyzed using the DISCERN instrument, rating each on a scale of 1 to 5. Each post was characterized by the author's profession (physician, physical therapist, chiropractor, etc.) and content type (educational, testimonial, personal, promotional, and entertainment). Popularity and engagement metrics such as "comments," "likes," and "shares" were also collected. Results There were 165,666,490 views on TT and 9,631,015 views on IG amongst the six common aforementioned orthopaedic conditions. Content created by physicians had less overall engagement (16.1%) compared to content created by non-physicians (83.9%). The quality of content on average was low (mean misinformation index 2.04 ± 1.08 (1-5)1. Physician-created posts in comparison to non-physician posts were significantly more accurate (mean misinformation index score 3.38 ± 1.12 vs 1.89 ± 0.94, p<0.0001). Conclusions Common orthopaedic conditions such as Achilles tendon tears, ACL tears, and meniscus tears are frequently the focus of content posted on TT and IG; however, this information is often not medically accurate. Increased physician engagement may help to rectify this misinformation.

RESUMO

OBJECTIVE: To understand caregiver, healthcare professional and national expert perspectives on implementation of a just-in-time adaptive intervention, RE-PACT (Respiratory Exacerbation-Plans for Action and Care Transitions) to prevent respiratory crises in severe cerebral palsy. DESIGN: Qualitative research study. SETTING: Paediatric complex care programmes at two academic medical institutions. PARTICIPANTS: A total of n=4 focus groups were conducted with caregivers of children with severe cerebral palsy and chronic respiratory illness, n=4 with healthcare professionals, and n=1 with national experts. METHODS: Participants viewed a video summarising RE-PACT, which includes action planning, mobile health surveillance of parent confidence to avoid hospitalisation and rapid clinical response at times of low confidence. Moderated discussion elicited challenges and benefits of RE-PACT's design, and inductive thematic analysis elicited implementation barriers and facilitators. RESULTS: Of the 19 caregivers recruited, nearly half reported at least one hospitalisation for their child in the prior year. Healthcare professionals and national experts (n=26) included physicians, nurses, respiratory therapists, social workers and researchers. Four overarching themes and their barriers/facilitators emphasised the importance of design and interpersonal relationships balanced against health system infrastructure constraints. Intervention usefulness in crisis scenarios relies on designing action plans for intuitiveness and accuracy, and mobile health surveillance tools for integration into daily life. Trust, knowledge, empathy and adequate clinician capacity are essential components of clinical responder-caregiver relationships. CONCLUSIONS: RE-PACT's identified barriers are addressable. Just-in-time adaptive interventions for cerebral palsy appear well-suited to address families' need to tailor intervention content to levels of experience, preference and competing demands.

RESUMO

Revision total knee arthroplasty (TKA) patients have a lower survival rate and lower post-surgical outcomes compared to primary TKA patients. Infection and aseptic loosening are the most common reasons for revision and re-revision TKAs, with infection accounting for nearly half of re-revision cases. To prevent infection, patient optimization addressing obesity, diabetes, malnutrition, and smoking cessation is crucial. Advancements in irrigation solutions, antibiotic-impregnated bone fillers, bacteriophage therapy, and electrochemical therapy hold promise for preventing infection. Technical strategies such as obtaining sufficient component fixation, joint line restoration, and using robot assistance may improve revision TKA outcomes. As the burden of revision TKA continues to rise, substantial efforts remain for mitigating future revision TKAs and their associated complications.

RESUMO

Plexiform schwannomas are rare, benign, neural crest-derived tumors that commonly occur in the hand and upper extremities. They may be sporadic or associated with neurofibromatosis type 2. Although previous literature has described plexiform schwannomas occurring in fingers, nerve and tendon sheaths, and intraosseous lesions, this is the first known case of a plexiform schwannoma of the thumb. This is a case of a growing, painless, subungual mass of the thumb in a 54-year-old patient. After surgical excision and subsequent immunohistochemical examination, the patient was diagnosed with a plexiform schwannoma. This highlights the importance of maintenance a broad differential before surgery and obtaining a proper diagnosis using histopathology.

RESUMO

Data quality has recently become a critical topic for the research community. European guidelines recommend that scientific data should be made FAIR: findable, accessible, interoperable and reusable. However, as FAIR guidelines do not specify how the stated principles should be implemented, it might not be straightforward for researchers to know how actually to make their data FAIR. This can prevent life-science researchers from sharing their datasets and pipelines, ultimately hindering the progress of research. To address this difficulty, we developed the BIBBOX, which is a platform that supports researchers publishing their datasets and the associated software in a FAIR manner.

RESUMO

Introducción: la enfermedad renal crónica representa un significativo problema de salud en el siglo XXI. Se han identificado diversos factores asociados a un incremento del daño renal y a la consecuente progresión de la enfermedad. Objetivo: analizar el comportamiento de los factores de progresión de la enfermedad renal crónica en pacientes atendidos en una consulta de Nefrología comunitaria. Materiales y métodos: estudio observacional, descriptivo y prospectivo. Se incluyeron 65 pacientes con enfermedad renal crónica, que tuvieron seguimiento estable durante un período de 12 meses en la consulta de Nefrología comunitaria, del municipio Pedro Betancourt, de la provincia Matanzas. Fueron analizadas variables sociodemográficas y las relacionadas con la enfermedad renal crónica (etiología, estadio, factores de progresión y marcadores de daño renal). Resultados: se constató una edad promedio de 68,79 años; el 64,6 % de los enfermos eran blancos; diabéticos el 46,15 %; se expusieron a nefrotóxicos el 93,8 %; el 56,9 % presentó proteinuria; el 66,1 % mostró estabilidad en la función renal, y seis factores de progresión concurrieron en pacientes con estadio 3b. Conclusiones: predominaron los pacientes blancos, longevos y con diabetes como enfermedad de base. Hubo una distribución equitativa en cuanto a sexo. El empleo de fármacos nefrotóxicos, y la proteinuria, hiperuricemia e hiperlipidemia, se destacaron como los principales factores de progresión; no obstante, sola la proteinuria, la anemia y la acidosis estuvieron asociadas estadísticamente con la posible progresión de la enfermedad, que no fue constatada en ningún paciente.


Introduction: chronic kidney disease represents a significant health problem in the 21st century. Various factors associated to kidney damage increase and to the consequent progression of the disease have been identified. Objective: to analyze the behavior of chronic kidney disease progression factors in patients treated in a community nephrology consultation. Materials and methods: observational, descriptive and prospective study. Sixty-five patients with chronic kidney disease that were stably followed up during a twelve-month period in the community nephrology consultation of the Pedro Betancourt municipality, province of Matanzas, were included. Socio-demographic variables and those related to chronic kidney disease (etiology, stage, progression factors, and kidney damage markers) were analyzed. Results: an average age of 68.79 years was found; 64.6% of the patients were white; 46.15% were diabetics; 93.8% were exposed to nephrotoxics; 56.9% presented proteinuria; 66.1% showed renal function stability, and six progression factors concurred in 3b stage patients. Conclusions: white, aged patients predominated, with diabetes as underlying disease. There was an equitable distribution in terms of gender. The use of nephrotoxic drugs, and proteinuria, hyperuricemia, and hyperlipidemia stood out as the main progression factors. However, only proteinuria, anemia and acidosis were statistically associated to the possible disease progression, which was not found in any patient.

RESUMO

BACKGROUND: Children with relapsed acute lymphoblastic leukemia (ALL) in low-income and middle-income countries rarely survive. The Pediatric Hematology-Oncology Association of Central America (AHOPCA) developed the AHOPCA-ALL REC 2014 protocol to improve outcomes in resource-constrained settings without access to stem cell transplantation. METHODS: The AHOPCA-ALL REC 2014 protocol was based on a modified frontline induction phase 1A, a consolidation therapy with six modified R-blocks derived from the ALL-Berlin-Frankfurt-Munster REZ 2002 protocol and intermittent maintenance therapy. Children with B-lineage ALL were eligible after a late medullary relapse, an early or late combined relapse, or any extramedullary relapses. Those with T-lineage ALL were eligible after early and late extramedullary relapses, as were those with both B-lineage and T-lineage relapses occurring at least 3 months after therapy abandonment. RESULTS: The study population included 190 patients with T-lineage (n = 3) and B-lineage (n = 187) ALL. Of those with B-lineage ALL, 25 patients had a very early extramedullary relapse, 40 had an early relapse (32 extramedullary and 8 combined), and 125 had a late relapse (34 extramedullary, 19 combined, and 72 medullary). The main cause of treatment failure was second relapse (52.1%). The 3-year event-free survival rate (± standard error) was 25.9% ± 3.5%, and the 3-year overall survival rate was 36.7% ± 3.8%. The 3-year event-free survival rate was 47.2% ± 4.7% for late relapses. The most frequently reported toxicity was grade 3 or 4 infection. Mortality during treatment occurred in 17 patients (8.9%), in most cases because of infectious complications. CONCLUSIONS: Selected children with relapsed ALL in Central America can be cured with second-line regimens even without access to consolidation with stem cell transplantation. Children in low-income and middle-income countries who have lower risk relapses of ALL should be treated with curative intent.

RESUMO

BACKGROUND: The National Institutes of Health (NIH) remains one of the predominant sources of biomedical research funding in the United States, yet its impact on total hip and knee arthroplasty research is poorly understood. This study defines the portfolio of NIH funding for total joint arthroplasty (TJA) and the impact of orthopaedic surgeons on this portfolio. METHODS: The Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER) database was queried for NIH grants that had been awarded for total hip and knee arthroplasty and total NIH funding from 2010 to 2020. Compound annual growth rates (CAGRs) were calculated. Funding totals were compared with those from 20 other clinical areas. The principal investigators (PIs) and grants were characterized, and comparisons were made with use of the Student t test. RESULTS: A total of 489 grants were awarded, totaling $181 million (CAGR of 10.3%). This was >3 times the growth rate for the total NIH budget (CAGR of 2.9%), which increased from $31.2 to $41.7 billion over the 11-year period. When compared with 20 other clinical areas, TJA received the least amount of NIH funding over that period. Alzheimer disease received the most funding ($12.1 billion, CAGR of 19.5%), and cerebral palsy received the penultimate amount of funding ($284 million, CAGR of 6.3%). The R01 grant mechanism was the predominant source (63.1%), and the Mayo Clinic (Rochester, Minnesota) received the most funding (9.7%). Departments of orthopaedic surgery were awarded the most funding (23.5%), yet only 20 orthopaedic surgeons were identified as PIs (16.0%). There were no significant differences in NIH funding totals by PI demographic and academic characteristics (p > 0.05), yet orthopaedic surgeons had among the highest Hirsch indices (h-indices) (p < 0.001). Funding supported clinical (63.5%), translational (19.3%), basic science (7.1%), and other types (10.1%) of research. The top areas with funding were postoperative complications (44.4%), postoperative pain management (17.6%), rehabilitation (15.1%), and implant design (12.4%). CONCLUSIONS: There is a paucity of orthopaedic surgeon representation among NIH grants awarded for TJA. Opportunities may exist for orthopaedic surgeons to collaborate in identified areas of clinical interest. Additional research is needed to understand the obstacles to obtaining NIH grant funding for orthopaedic surgeon PIs. CLINICAL RELEVANCE: Increasing the levels of funding from the NIH is a strategic priority for departments of orthopaedic surgery. Understanding levels of funding for clinical areas in total joint arthroplasty is critical to foster research and discovery support from the NIH.

RESUMO

Three-dimensional printing (3DP) has recently gained importance in the medical industry, especially in surgical specialties. It uses different techniques and materials based on patients' needs, which allows bioprofessionals to design and develop unique pieces using medical imaging provided by computed tomography (CT) and magnetic resonance imaging (MRI). Therefore, the Department of Biology and Medicine and the Department of Physics and Engineering, at the Bioastronautics and Space Mechatronics Research Group, have managed and supervised an international cooperation study, in order to present a general review of the innovative surgical applications, focused on anatomical systems, such as the nervous and craniofacial system, cardiovascular system, digestive system, genitourinary system, and musculoskeletal system. Finally, the integration with augmented, mixed, virtual reality is analyzed to show the advantages of personalized treatments, taking into account the improvements for preoperative, intraoperative planning, and medical training. Also, this article explores the creation of devices and tools for space surgery to get better outcomes under changing gravity conditions.

RESUMO

OBJECTIVE: Unstructured parental comments could solicit important information about children's asthma, yet are rarely captured in clinical asthma questionnaires. This mixed-methods study describes parents' written responses to an open-ended question in a validated asthma questionnaire. METHODS: The Pediatric Asthma Control and Communication Instrument (PACCI) asthma questionnaire was administered to parents of children with asthma symptoms presenting to 48 pediatric primary care offices (PPCP), 1 pediatric pulmonology office, and 1 emergency department (ED). Responses to the question, "Please write down any concern or anything else you would like your doctor to know about your child's asthma" were analyzed using a phenomenological approach until thematic saturation was achieved for each site. Logistic regressions tested whether sociodemographic and clinical characteristics were associated with responding to the open-ended question. RESULTS: Of 7,988 parents who completed the PACCI, 954 (12%) responded to the open-ended question-2% in PPCP, 31% in the ED, and 50% in the pulmonary setting. More severe asthma was associated with higher odds of responding (odds ratio, 2.01; 95% confidence interval, 1.42-2.84). Based on responses provided, we identified 3 communication types: 1) clarifying symptoms, 2) asking questions, and 3) communicating distress. Responses also covered 5 asthma-related themes: 1) diagnostic uncertainty, 2) understanding asthma etiology and prognosis, 3) medication management, 4) impact on child function, and 5) personal asthma characteristics. CONCLUSION: Parents of children with severe asthma provided clarifying details, asked questions, and relayed health concerns and distress. None of these topics may be easily captured by closed-ended asthma questionnaires.

RESUMO

AIM: To determine the professional profile and the work conditions of nurses working in intensive care units (ICU) in Colombia, Argentina, Peru and Brazil. BACKGROUND: ICUs require a differentiated professional profile to provide quality care, and appropriate working conditions, leading to a transformation of care and management practices. DESIGN: Descriptive multicentre cross-sectional observational study. METHODS: An online survey was applied to identify both the characteristics of the professional profile and the working conditions. 1,427 ICU nursing professionals were included. RStudio statistical software was used for the analysis of the information. Descriptive statistics were used for the presentation of the results. The STROBE checklist for cross-sectional studies was used in this study. RESULTS: Only 33.6% of the professionals had a specialisation degree in intensive care. The skills that were most frequently put into practice were communication (68.5%) and care management (78.5%). The most predominant nurse-to-patient ratios were 1:2, and greater than 1:6. 59.1% of the nurses had an indefinite term contract, 38.8% worked 48 hours per week and 49.8% had rotating shifts. Only 50.4% of them received incentives. The average salary ranged between 348 and 1,500 USD. 64.5% of the participants were satisfied with their job. CONCLUSION: It is necessary to strengthen nurses' professional profile by promoting both postgraduate education and the development of troubleshooting and teamwork skills. It is necessary to standardise the nurse-to-patient ratio, improve wages and increase incentives to achieve greater job satisfaction. RELEVANCE TO PRACTICE: The knowledge and the improvement of both the professional profile and the work conditions of nurses working in intensive care units will improve the quality of the care given to critical patients and, therefore, the quality of health outcomes.

RESUMO

La anemia de células falciformes (ACF) es la hemoglobinopatía hereditaria más común en el mundo. El diagnóstico definitivo se hace por electroforesis de hemoglobina (EFH), relativamente costosa. Por ello ante la sospecha diagnóstica se solicita Metabisulfito de sodio al 2% (MS2), que tiene un menor costo, aporta solo resultados cualitativos, y la confiabilidad depende de quien interprete. Se busca una alternativa económicamente accesible y con mayor certeza diagnóstica. Objetivo: describir y comparar los valores de Hemoglobina S (HbS) obte- nidos mediante cromatografía líquida de alta presión (CLAP) y electroforesis de hemoglobina. Pacientes y Métodos: investigación cuantitativa, descriptiva, no experimental, en las comuni- dades de Masca y Pueblo Nuevo, Omoa, Cortés, en el 2017. Las comunidades tienen 2545 habitantes, de quienes se tomó muestra probabilística de 369. Encontrando 20 personas con prueba de MS2 positiva. En estos 20 casos se solicitó también CLAP y EFH. Los datos fueron analizados con SPSS versión 23, calculando frecuencias, porcentajes y medidas de tendencia central. Resultados: El 50% de los casos eran fenotípicamente mestizos. Los valores de CLAP estuvieron comprendidos entre 26.1% y 68.3% y los de electroforesis de hemoglobina entre 27.3% y 100%. La media aritmética de CLAP fue de 35.53 vs 45.3 para EFH. Conclu- sión: El valor de Hb S medido por EFH es cercano al obtenido por CLAP, por lo que este método podría usarse para un diagnóstico más rápido y a menor costo...(AU)

RESUMO

Las actitudes reflejan los antecedentes y las experiencias de una persona, se adoptan en razón de un conjunto de fuerzas como la personalidad, valores y creencias de cada uno. La enfermedad de células falciformes es una patología genética, crónica que constituye la forma más frecuente y mejor conocida de hemoglobinopatía estructural. El objetivo, fue determinar las actitudes (en sus componentes cognitivo y afectivo) que presentan los pobladores de Masca y Pueblo Nuevo, en Omoa, Cortés hacia la anemia drepanocítica. Se realizó un estudio cuantitativo, no experimental, transeccional y alcance descriptivo. Población: 274 personas alfabetos, de 15 años o más, muestreo probabilístico: 148 personas, voluntarias anuentes a participar en la investigación. Se elaboró un instrumento tipo escala de Likert constituido por 20 ítems que midieron las actitudes hacia la anemia drepanocítica. El análisis estadístico se realizó con el programa Microsoft Excel. Los resultados ante el componente cognitivo indicaron que 65 personas, (44 %) consideraron tener conocimientos sobre la temática y reconocieron que es necesario se informe sobre la enfermedad. 19 personas (13 %) estaban inseguras de emitir una respuesta; 78 (53 %) manifestaron que, a pesar de tener algún tipo de conocimientos en torno a la enfermedad, requieren más información. En cuanto al componente afectivo, 58 (39 %) manifestaron experimentar temor ante la idea de enfrentarse a este tipo de enfermedad; 30 (20 %) se mostraron inseguras o indiferentes de emitir una respuesta y 61 (41 %) manifestaron que no sabrían que hacer o cómo actuar ante la idea de que ellos o alguien de su familia padezcan de la enfermedad. Se concluyó que existe la necesidad de informar a la población, sobre anemia drepanocítica para saber cómo enfrentarla, tanto a nivel individual como colectivamente.


Attitudes reflect the antecedents and experiences of a person, they are adopted due to a set of forces such as the personality, values and beliefs of each one. Sickle cell disease is a chronic, genetic pathology that is the most common and best known form of structural hemoglobinopathy. The objective was to determine the attitudes (in its cognitive and affective components) that the inhabitants of Masca and Pueblo Nuevo, in Omoa, Cortés have towards sickle cell anemia. A quantitative, non- experimental, transectional study with a descriptive scope was carried out. Population: 274 literate people, aged 15 or over, probability sampling: 148 people, volunteers willing to participate in the research. A Likert scale instrument was developed consisting of 20 items that measured attitudes towards sickle cell anemia. Statistical analysis was carried out with the Microsoft Excel program. The results regarding the cognitive component indicated that 65 people (44%) considered they had knowledge about the subject and recognized that it is necessary to inform themselves about the disease. 19 people (13%) were unsure about giving an answer; 78 (53%) stated that, despite having some kind of knowledge about the disease, they require more information. Regarding the affective component, 58 (39%) expressed fear at the idea of facing this type of illness; 30 (20%) were unsure or indifferent to issue a response and 61 (41%) stated that they would not know what to do or how to act when faced with the idea that they or someone in their family had the disease. It was concluded that there is a need to inform the population about sickle cell anemia in order to know how to deal with it, both individually and collectively.

RESUMO

BACKGROUND: Spinal anesthetic choice plays an underappreciated role in total hip arthroplasty (THA). Chloroprocaine, a short-acting local anesthetic, has been limited to short-duration ambulatory procedures and has not been studied in THA. We compare perioperative outcomes of patients undergoing fast-track THA using chloroprocaine spinal anesthesia with those who have surgery with a longer-acting agent (bupivacaine). METHODS: A total of 143 THAs performed under spinal anesthesia by 3 arthroplasty surgeons between November 2018 and July 2019 were retrospectively reviewed. Patients receiving chloroprocaine were matched 1:1 by demographics to patients receiving bupivacaine. Ultimately, 74 patients were included (37 chloroprocaine and 37 bupivacaine). The primary outcome was hospital length of stay (LOS). Other perioperative outcomes were also evaluated. RESULTS: A total of 37 patients (50%) received chloroprocaine (60 mg), whereas 37 (50%) received bupivacaine (median 10 mg, range 8-15 mg). Among the matched groups, chloroprocaine use was associated with shorter hospital LOS (0.9 vs 1.2 days; P = .03), shorter operative time (68.2 vs 83.6 minutes, P = .03), lower estimated blood loss (184.7 vs 218.9 mL, P = .02), shorter postanesthesia care unit LOS (139.4 vs 194.9 minutes; P = .04), and less intraoperative hypotension (59.5% vs 83.8%, P = .02). Patients receiving chloroprocaine were also more commonly discharged home (100% vs 89.2%; P = .04). CONCLUSION: Chloroprocaine is a safe and reliable option for patients to mobilize rapidly and leave the hospital sooner after THA. Compared with bupivacaine, it is associated with shorter hospital LOS and higher likelihood for discharge to home.

RESUMO

Introduction: The Minimum Information About BIobank data Sharing (MIABIS) was initiated in 2012. MIABIS aims to create a common biobank terminology to facilitate data sharing in biobanks and sample collections. The MIABIS Core terminology consists of three components describing biobanks, sample collections, and studies, in which information on samples and sample donors is provided at aggregated form. However, there is also a need to describe samples and sample donors at an individual level to allow more elaborate queries on available biobank samples and data. Therefore the MIABIS terminology has now been extended with components describing samples and sample donors at an individual level. Materials and Methods: The components were defined according to specific scope and use cases by a large group of experts, and through several cycles of reviews, according to the new MIABIS governance model of BBMRI-ERIC (Biobanking and Biomolecular Resources Research Infrastructure-European Research Infrastructure Consortium). The guiding principles applied in developing these components included the following terms: model should consider only samples of human origin, model should be applicable to all types of samples and all sample donors, and model should describe the current status of samples stored in a given biobank. Results: A minimal set of standard attributes for defining samples and sample donors is presented here. We added an "event" component to describe attributes that are not directly describing samples or sample donors but are tightly related to them. To better utilize the generic data model, we suggest a procedure by which interoperability can be promoted, using specific MIABIS profiles. Discussion: The MIABIS sample and donor component extensions and the new generic data model complement the existing MIABIS Core 2.0 components, and substantially increase the potential usability of this terminology for better describing biobank samples and sample donors. They also support the use of individual level data about samples and sample donors to obtain accurate and detailed biobank availability queries.

RESUMO

Introducción: El riñón en esponja es una malformación renal, de los túbulos colectores, que se suele asociar a nefrocalcinosis o acidosis tubular distal. La asociación con la litiasis renal se observa entre un 4-20%. Objetivo: El objetivo de nuestro trabajo fue describir factores de riesgo bioquímicos para litiasis renales, en pacientes con riñón en esponja. Material y métodos: Se realizó un estudio retrospectivo, observacional de corte, entre los años 2000 y 2017 en donde se estudiaron 37 pacientes con riñón en esponja y litiasis renal (26 mujeres y 11 hombres) de 37.3 ± 13.2 años. El diagnóstico de riñón en esponja se hizo mediante urograma excretor. Resultados: Fue observada nefrocalcinosis en el 95%. El diagnóstico bioquímico más frecuente fue la hipercalciuria idiopática que como única y asociada alteración se observó en el 59.4%. La hiperuricosuria fue el segundo diagnóstico encontrado en el 32.4% (única y asociada) seguido por la, hipocitraturia, hipomagnesuria y el pHu persistentemente ácido. En los hombres llamó la atención que un 46.2% no presentaron alteración bioquímica. Conclusiones: En conclusión se destaca la asociación relativamente frecuente de riñón en esponja y litiasis renal. La hipercalciuria idiopática fue la alteración metabólica más frecuente como causa de litogénesis, seguida por la hiperuricosuria, similar a lo descripto en la literatura, aunque en menor proporción. Otras alteraciones, como la hipocitraturia, hipomagnesuria y pHu persistentemente ácido también deben ser consideradas en el estudio de estos pacientes.


Introduction: Sponge kidney is a renal malformation of the collecting tubules, which is usually associated with nephrocalcinosis or distal tubular acidosis. The association with renal lithiasis is observed between 4-20%. Objective: The aim of our work was to describe the biochemical risk factors of renal lithiasis in patients with sponge kidney. Methods: A retrospective, observational, cross-sectional study was conducted between 2000 and 2017, in which 37 patients with sponge kidney and renal lithiasis (26 women and 11 men), aged 37.3 ± 13.2 years, were studied. The diagnosis of sponge kidney was made by excretory urography. Results: Nephrocalcinosis was observed in 95% of patients. The most frequent biochemical diagnosis was idiopathic hypercalciuria, which was observed, as a single and associated alteration, in 59.4% of cases. Hyperuricosuria was the second diagnosis found in 32.4% (single and associated) followed by hypocitraturia, hypomagnesuria and persistently acid pHu. Surprisingly, 46.2% of men presented no biochemical alteration. Conclusions: Our findings highlight the relatively frequent association of sponge kidney and renal lithiasis. Idiopathic hypercalciuria was the most common metabolic alteration as the cause of lithogenesis, followed by hyperuricosuria, similar to that described in the literature, but to a lesser extent. Other alterations, such as hypocitraturia, hypomagnesuria and persistently acid pHu, should also be considered in the study of these patients.

RESUMO

BACKGROUND: Treating B-non-Hodgkin lymphoma (B-NHL) in lower-income countries is challenging because of imprecise diagnosis, the increased risk of fatal toxicity associated with advanced disease at presentation, and limited supportive care. PROCEDURE: Central American patients with newly diagnosed stage I or II B-NHL received a modified Berlin-Frankfurt-Münster (BFM) regimen including a prephase (prednisone, cyclophosphamide) followed by A/B/A courses (A: cytarabine, dexamethasone, etoposide, ifosfamide, methotrexate, and intrathecal therapy; B: cyclophosphamide, dexamethasone, doxorubicin, methotrexate, and intrathecal therapy). Those with stage III or IV NHL received additional courses (B/A/B), intensified for stage IV disease by additional vincristine and methotrexate doses. Patients in poor condition received a second prephase treatment before their chemotherapy courses. RESULTS: Between March 2004 and June 2016, of 405 patients with B-NHL, 386 (109 females) were eligible for treatment. Immunohistochemistry was performed in 177 cases (47.4%) and characterized the disease as mature B-cell lymphoma. Stage distribution was as follows: I/II, 31 (8.1%); III, 252 (65.3%); IV, 93 (24.1%); 10 (2.6%) not available. The 3-year overall survival was 70% for the whole group (86% for stages I/II, 75% for stage III, 58% for stage IV). Events included death during induction (34 patients, 8.8%), relapse/progression (46, 11.9%), death in remission (9, 2.3%), second malignancy (1, 0.26%), and death of unknown cause (1, 0.26%). Twenty-three (6%) patients abandoned or refused therapy. CONCLUSIONS: Approximately 70% of children with B-NHL from Central America experienced long-term, disease-free survival with a modified BFM schedule. Toxic death and relapse/resistant disease were the main reasons for treatment failure.
