RESUMO

Pulmonary contusion (PC), defined as damage to the lung parenchyma with edema and hemorrhage, has classically been associated with acceleration-deceleration injuries. It is a frequent pathology in clinical practice. However, its clinical presentation and imaging findings are nonspecific. Patients with this entity can present with findings that can range from mild dyspnea to life-threatening respiratory failure and hemodynamic instability. We present the case of a 61-year-old man, a former smoker, who presented to the emergency department after suffering blunt chest trauma. On admission, he complained of only mild shortness of breath, and his vital signs were typical. Initial imaging identified asymmetric pulmonary infiltrates and mediastinal lymphadenopathy; this was suspicious for additional pathology in addition to PC. After an exhaustive evaluation, a neoplastic or infectious disease process was ruled out. Even though the patient presented with a clinical deterioration of respiratory function compatible with secondary acute respiratory distress syndrome, there was a complete recovery after supportive measures and supplemental oxygen. In conclusion, the nonspecific clinical and imaging findings in patients with pulmonary contusion warrant a complete evaluation of these cases. An early diagnosis is essential to establish adequate support and monitoring to prevent possible complications that could worsen the patient's prognosis.

RESUMO

OBJECTIVES: Blunt abdominal trauma is a common cause of emergency department admission. Computed tomography (CT) scanning is the gold standard method for identifying intra-abdominal injuries in patients experiencing blunt trauma, especially those with high-energy trauma. Although the diagnostic accuracy of this imaging technique is very high, patient admission and prolonged observation protocols are still common practices worldwide. We aimed to evaluate the incidence of intra-abdominal injury in hemodynamically stable patients with high-energy blunt trauma and a normal abdominal CT scan at a Level-1 Trauma Center in Colombia, South America, to assess the relevance of a prolonged observation period. METHODS: We performed a retrospective study of patients admitted to the emergency department for blunt trauma between 2021 and 2022. All consecutive patients with high-energy mechanisms of trauma and a normal CT scan at admission were included. Our primary outcomes were the incidence of intra-abdominal injury identified during a 24-hour observation period or hospital stay, ICU admission, and death. RESULTS: We included 480 patients who met the inclusion criteria. The median age was 33 (IQR 25.5, 47), and 74.2% were male. The most common mechanisms of injury were motor vehicle accidents (64.2%), falls from height (26%), and falls from bikes (3.1%). A total of 99.2% of patients had a Revised Trauma Score of 8. Only 1 patient (0.2%) (95% CI: 0.01-1.16) presented with an abdominal injury during the observation period. No ICU admissions or deaths were reported. CONCLUSION: The incidence of intra-abdominal injury in patients with hemodynamically stable blunt trauma and a negative abdominal CT scan is extremely low, and prolonged observation may not be justified in these patients.

RESUMO

Peritoneal metastases (PM) occur when cancer cells spread inside the abdominal cavity and entail an advanced stage of colorectal cancer (CRC). Prognosis, which is poor, correlates highly with tumour burden, as measured by the peritoneal cancer index (PCI). Cytoreductive surgery (CRS) in specialized centres should be offered especially to patients with a low to moderate PCI when complete resection is expected. The presence of resectable metastatic disease in other organs is not a contraindication in well-selected patients. Although several retrospective and small prospective studies have suggested a survival benefit of adding hyperthermic intraperitoneal chemotherapy (HIPEC) to CRS, the recently published phase III studies PRODIGE-7 in CRC patients with PM, and COLOPEC and PROPHYLOCHIP in resected CRC with high-risk of PM, failed to show any survival advantage of this strategy using oxaliplatin in a 30-min perfusion. Final results from ongoing randomized phase III trials testing CRS plus HIPEC based on mitomycin C (MMC) are awaited with interest. In this article, a group of experts selected by the Spanish Group for the Treatment of Digestive Tumours (TTD) and the Spanish Group of Peritoneal Oncologic Surgery (GECOP), which is part of the Spanish Society of Surgical Oncology (SEOQ), reviewed the role of HIPEC plus CRS in CRC patients with PM. As a result, a series of recommendations to optimize the management of these patients is proposed.

RESUMO

BACKGROUND: Previous observational studies showed higher rates of abdominal wall closure with the use of hypertonic saline in trauma patients with abdominal injuries. However, no randomized controlled trials have been performed on this matter. This double-blind randomized clinical trial assessed the effect of 3% hypertonic saline (HS) solution on primary fascial closure and the timing of abdominal wall closure among patients who underwent damage control laparotomy for bleeding control. METHODS: Double-blind randomized clinical trial. Patients with abdominal injuries requiring damage control laparotomy (DCL) were randomly allocated to receive a 72-h infusion (rate: 50 mL/h) of 3% HS or 0.9 N isotonic saline (NS) after the index DCL. The primary endpoint was the proportion of patients with abdominal wall closure in the first seven days after the index DCL. RESULTS: The study was suspended in the first interim analysis because of futility. A total of 52 patients were included. Of these, 27 and 25 were randomly allocated to NS and HS, respectively. There were no significant differences in the rates of abdominal wall closure between groups (HS: 19 [79.2%] vs. NS: 17 [70.8%]; p = 0.71). In contrast, significantly higher hypernatremia rates were observed in the HS group (HS: 11 [44%] vs. NS: 1 [3.7%]; p < 0.001). CONCLUSION: This double-blind randomized clinical trial showed no benefit of HS solution in primary fascial closure rates. Patients randomized to HS had higher sodium concentrations after the first day and were more likely to present hypernatremia. We do not recommend using HS in patients undergoing damage control laparotomy. Trial registration The trial protocol was registered in clinicaltrials.gov (identifier: NCT02542241).

RESUMO

BACKGROUND: Reported risk of bleeding complications after central catheter access in patients with thrombocytopenia is highly variable. Current guidelines recommend routine prophylactic platelet (PLT) transfusion before central venous catheter placement in patients with severe thrombocytopenia. Nevertheless, the strength of such recommendations is weak and supported by observational studies including few patients with very low PLT counts (<20 × 109 /L). This study aims to assess the risk of bleeding complications related to using or not using prophylactic PLT transfusion before ultrasound-guided central venous access in patients with very low PLT counts. METHODS: This was a retrospective cohort study of patients with very low PLT counts (<20 × 109 /L) subjected to ultrasound-guided central venous catheterization between January 2011 and November 2019 in a university hospital. Bleeding complications were graded according to the Common Terminology Criteria for Adverse Events. A multivariate logistic regression was conducted to assess the risk of major and minor bleeding complications comparing patients who did or did not receive prophylactic PLT transfusion for the procedure. Multiple imputation by chained equations was used to handle missing data. A two-tailed p < 0.05 was considered statistically significant. RESULTS: Among 221 patients with very low PLT counts, 72 received prophylactic PLT transfusions while 149 did not. Baseline characteristics were similar between transfused and nontransfused patients. No major bleeding events were identified, while minor bleeding events were recognized in 35.7% of patients. Multivariate logistic regression analysis showed no significant differences in bleeding complications between patients who received prophylactic PLT transfusions and those who did not (odds ratio 0.83, 95% confidence interval 0.45-1.55, p = 0.567). Additional complete case and sensitivity analyses yielded results similar to those of the main analysis. CONCLUSIONS: In this single-center retrospective cohort study of ultrasound-guided central venous access in patients with very low PLT counts, no major bleeding was identified, and prophylactic PLT transfusions did not significantly decrease minor bleeding events.

RESUMO

BACKGROUND: Penetrating diaphragmatic injuries are associated with a high incidence of posttraumatic empyema. We analyzed the contribution of trauma severity, specific organ injury, contamination severity, and surgical management to the risk of posttraumatic empyema in patients who underwent surgical repair of diaphragmatic injuries at a level 1 trauma center. METHODS: This is a retrospective review of the patients who survived more than 48 h. Univariate OR calculations were performed to identify potential risk factors. Multiple logistic regression was used to calculate adjusted ORs and identify independent risk factors. RESULTS: We included 192 patients treated from 2011 to 2020. There were 169 (88.0) males. The mean interquartile range, (IQR) of age, was 27 (22-35) years. Gunshot injuries occurred in 155 subjects (80.7%). Mean (IQR) NISS and ATI were 29 (18-44) and 17 (10-27), respectively. Thoracic AIS was > 3 in 38 patients (19.8%). Hollow viscus was injured in 105 cases (54.7%): stomach in 65 (33.9%), colon in 52 (27.1%), small bowel in 42 (21.9%), and duodenum in 10 (5.2%). Visible contamination was found in 76 patients (39.6%). Potential thoracic contamination was managed with a chest tube in 128 cases (66.7%), with transdiaphragmatic pleural lavage in 42 (21.9%), and with video-assisted thoracoscopy surgery or thoracotomy in 22 (11.5%). Empyema occurred in 11 patients (5.7%). Multiple logistic regression identified thoracic AIS > 3 (OR 6.4, 95% CI 1.77-23. 43), and visible contamination (OR 5.13, 95% IC 1.26-20.90) as independent risk factors. The individual organ injured, or the method used to manage the thoracic contamination did not affect the risk of posttraumatic empyema. CONCLUSION: The severity of the thoracic injury and the presence of visible abdominal contamination were identified as independent risk factors for empyema after penetrating diaphragmatic trauma.

RESUMO

Glioblastoma (GBM) is the most common and deadly malignant brain tumor, with a median survival of 15 to 17 months for a patient. GBM contains a cellular subpopulation known as GBM stem-like cells (GSCs) that persist in hypoxic niches and are capable of infiltrating into healthy brain tissue. For this reason, GSCs are considered one of the main culprits for GBM recurrence. A hypoxic microenvironment increases extracellular adenosine levels, activating the low affinity A2B adenosine receptor (A2BAR). Adenosine, through A2BAR, is capable of modulating invasiveness. However, its role in the invasion/migration of hypoxic-GSCs is still unknown. This study aims to understand the importance of A2BAR in modulating the migratory/invasive capacity of GSCs under hypoxia. Data analysis from The Cancer Genome Atlas (TCGA) program correlates A2BAR expression with high-grade glioma and hypoxic necrotic areas. U87MG and primary culture-derived GSCs under hypoxic conditions (0.5% O2) increased A2BAR mRNA and protein levels. As expected, the migratory and invasive capacity of GSCs increased under hypoxia, which was counteracted by blocking A2BAR, through the downregulation of MMP9 activity and epithelial-mesenchymal transition marker expression. Finally, in a xenograft mouse model, we demonstrate that treatment with MRS1754 did not affect the tumor volume but could decrease blood vessel formation and VEGF expression. Our results suggest that extracellular adenosine, through the activation of A2BAR, enhances the migratory and invasive capacity of GSCs in vitro under hypoxic conditions. Targeting A2BAR can be an effective therapy for GBM recurrence.

RESUMO

RESUMEN Fundamento: la disección coronaria espontánea, aunque infrecuente, es causa de infarto agudo de miocardio. Objetivo: presentar el caso de una paciente con disección coronaria espontánea como causa de infarto agudo de miocardio. Presentación del caso: paciente de 55 años, raza blanca, sexo femenino, con antecedentes de hipertensión arterial esencial sistodiastólica estadio I controlada, sobrepeso, que asociado a esfuerzo físico comienza con dolor precordial típico de enfermedad coronaria. Tras realización de estudios con biomarcadores de daño miocárdico, electrocardiográficos e imagenológicos se diagnostica un síndrome coronario agudo sin elevación del ST, tipo infarto agudo de miocardio no Q, Killip Kimball I; se realiza estudio coronariográfico con diagnóstico de disección coronaria espontánea, se opta por tratamiento conservador con adecuada evolución de la paciente. Conclusiones: la disección coronaria espontánea, aunque infrecuente es causa de infarto agudo de miocardio. Su presentación clínica puede ser similar a la de un síndrome coronario agudo de causa ateroesclerótica. La coronariografía es una prueba valiosa para el diagnóstico. Según sea el caso se puede elegir un tratamiento médico conservador, endovascular con colocación de stent o quirúrgico.


ABSTRACT Background: the spontaneous coronary artery dissection causes an acute myocardial infarction. Objective: to present the case of a patient suffering from spontaneous coronary artery dissection, this causes an acute myocardial infarction. Case report: a 55 years old, white, female patient with antecedents of essential systodiastolic systemic arterial hypertension stage I, overweight. Related to a physical effort, the patient begins complaining of an oppressive pre-cordial pain with typical characteristics of coronary illness. After the performance of cardiac biomarkers, electrocardiographic and imaging studies was diagnosed a non ST segment elevation acute coronary syndrome type Q, Killip Kimball I acute myocardial infarction; after that a corona-graphic study was carried out with a diagnostic of spontaneous coronary dissection, and it was decided a conservative treatment, with a good recovery. Conclusion: the spontaneous coronary artery dissection, although infrequently, is cause of acute myocardial infarction. Its clinical presentation can be similar to an acute coronary syndrome caused by an atherosclerotic coronary artery disease. The coronary angiography is a valuable test for the diagnosis. As it is the case we can choose between a conservative, endovascular with stent placement treatment or surgical treatment.

RESUMO

Red blood cell transfusion is thought to improve cell respiration during septic shock. Nevertheless, its acute impact on oxygen transport and metabolism in this condition remains highly debatable. The objective of this study was to evaluate the impact of red blood cell transfusion on microcirculation and oxygen metabolism in patients with sepsis and septic shock. We conducted a search in the MEDLINE®, Elsevier and Scopus databases. We included studies conducted in adult humans with sepsis and septic shock. A systematic review and meta-analysis were performed using the DerSimonian and Laird random-effects model. A p value < 0.05 was considered significant. Nineteen manuscripts with 428 patients were included in the analysis. Red blood cell transfusions were associated with an increase in the pooled mean venous oxygen saturation of 3.7% (p < 0.001), a decrease in oxygen extraction ratio of -6.98 (p < 0.001) and had no significant effect on the cardiac index (0.02L/minute; p = 0,96). Similar results were obtained in studies including simultaneous measurements of venous oxygen saturation, oxygen extraction ratio, and cardiac index. Red blood cell transfusions led to a significant increase in the proportion of perfused small vessels (2.85%; p = 0.553), while tissue oxygenation parameters revealed a significant increase in the tissue hemoglobin index (1.66; p = 0.018). Individual studies reported significant improvements in tissue oxygenation and sublingual microcirculatory parameters in patients with deranged microcirculation at baseline. Red blood cell transfusions seemed to improve systemic oxygen metabolism with apparent independence from cardiac index variations. Some beneficial effects have been observed for tissue oxygenation and microcirculation parameters, particularly in patients with more severe alterations at baseline. More studies are necessary to evaluate their clinical impact and to individualize transfusion decisions.

Incluíram-se na análise 19 manuscritos, correspondentes a 428 pacientes. As transfusões de eritrócitos se associaram com aumento de 3,7% na média combinada de saturação venosa mista de oxigênio (p < 0,001), diminuição de razão de extração de oxigênio de -6,98 (p < 0,001) e nenhum efeito significante no índice cardíaco (0,02 L/minuto; p = 0,96). Obtiveram-se resultados similares em estudos que incluíram mensurações simultâneas de saturação venosa mista de oxigênio, razão de extração de oxigênio e índice cardíaco. As transfusões de eritrócitos levaram a aumento significante na proporção de pequenos vasos perfundidos (2,85%; p = 0,553), enquanto os parâmetros de oxigenação tissular revelaram aumento significante no índice de hemoglobina tissular (1,66; p = 0,018). Estudos individuais relataram melhoras significantes na oxigenação tissular e nos parâmetros microcirculatórios sublinguais em pacientes com microcirculação alterada na avaliação inicial. A transfusão de eritrócitos pareceu melhorar o metabolismo sistêmico de oxigênio com aparente independência de variações no débito cardíaco. Observaram-se alguns efeitos benéficos para a oxigenação tissular e parâmetros microcirculatórios, em particular em pacientes com alterações iniciais mais graves. São necessários mais estudos para avaliar seu impacto clínico e individualizar as decisões relativas à transfusão.

RESUMO

PURPOSE: The purpose of this study was to examine the association of REBOA and mortality in a group of patients with penetrating trauma to the torso, treated in a level-I trauma center from Colombia. METHODS: In a retrospective cohort study, patients with penetrating trauma, requiring emergency surgery, and treated between 2014 and 2018, were included. The decision to use or not use REBOA during emergent surgery was based on individual surgeon's opinion. A propensity score (PS) was calculated after adjusting for age, clinical signs on admission (systolic blood pressure, cardiac rate, Glasgow coma scale), severe trauma in thorax and abdomen, and the presence of non-compressive torso hemorrhage. Subsequently, logistic regression for mortality was adjusted for the number of red blood cells (RBC) transfused within the first six hours after admission, injury severity score (ISS), and quintiles of PS. RESULTS: We included 345 patients; 28 of them (8.1%) were treated with REBOA. Crude mortality rates were 17.9% (5 patients) in REBOA group and 15.3% (48 patients) in control group (p = 0.7). After controlling for RBC transfused, ISS, and the PS, the odds of death in REBOA group was 78% lower than that in the control group (odds ratio [OR] 0.20, 95% confidence interval [95%CI] 0.05-0.77, p = 0.01). CONCLUSION: We found that, when compared to no REBOA use, patients treated with REBOA had lower risk-adjusted odds of mortality. These findings should be interpreted with caution and confirmed in future comparative studies, if possible.

RESUMO

A series of carbohydrate-linked 1,2,3-triazole derivatives were synthesized in good yields from glucofuranose and allofuranose diacetonides using as key step a three-component 1,3-dipolar azide-alkyne cycloaddition catalysed by a Cu-Al mixed oxide. In this multi-component reaction, Cu-Al mixed oxide/sodium ascorbate system serves as a highly reactive, recyclable and efficient heterogeneous catalyst for the regioselective synthesis of 1,4-disubstituted 1,2,3-triazoles. The reported protocol has significant advantages over classical CuI/N,N-diisopropylethylamine (DIPEA) or CuSO4/sodium ascorbate conditions in terms of efficiency and reduced synthetic complexity. In addition, the selective deprotection of synthesized di-O-isopropylidene derivatives was also carried out leading to the corresponding mono-O-isopropylidene products in moderate yields. Some of the synthesized triazole glycoconjugates were tested for their in vitro antimicrobial activity using the disc diffusion method against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis), Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), as well as fungus (Aspergillus niger) and yeast (Candida utilis). The results revealed that these compounds exhibit moderate to good antimicrobial activity mainly against Gram-negative bacteria.

RESUMO

BACKGROUND: Abdominal compartment syndrome is a sustained intra-abdominal pressure (IAP) >20 mm Hg associated with new organ dysfunction. In order to prevent its development and related complications, IAP monitoring should be performed in patients with risk factors. Although techniques for its monitoring have been developed, they are of high cost and not always available in low- and lower-middle-income countries. Therefore, we aim to develop and validate in a bench model a handcrafted catheter to be used as an alternative method to measure the intra-gastric pressure (IGP) as a surrogate of the IAP. METHODS: We used an acrylic water container as a model of the abdomen and four handcrafted catheters made of a 16 Fr Levin tube with a globe finger tied with silk in the distal end, inflated with 1 cm of air. They were placed on the bottom of the container where the water pressure was directly measured as a gold standard. The agreement between the two measures was assessed with the Bland-Altman method. RESULTS: We performed 120 simultaneous measures. The mean pressure difference was 0.218 (95% CI 0.074 to 0.363). CONCLUSIONS: The handcrafted prototype catheter and the direct measure were highly correlated. The new catheter is a reliable and reproducible tool for pressure monitoring. However, before it can be used in the clinical setting for IAP monitoring, validation in human models in a real clinical setting needs to be performed.

RESUMO

BACKGROUND: The Ecuadorian population forms the largest Latin American immigrant group in Spain. However, their knowledge about the brain death (BD) concept and the relationship with the attitude toward organ donation has been little analyzed. The objective of the study is to analyze the knowledge of the BD concept among the Ecuadorian population resident in Spain. METHODS: The population under study was the population born in Ecuador and resident in Spain. Inclusion criterion was age older than 15 years stratified by age and sex. The assessment instrument was PCID-DTO-Ríos, a validated questionnaire of attitude toward donation and organ transplantation. Field work involved random selection of respondents based on stratification. The support of immigration support associations was required to obtain sample locations. The completion was anonymous and self-administered. RESULTS: Of the 461 respondents, 22% (n =102) know the BD concept and accept it as the death of the person; 61% (n = 283) do not know it; and for 17% (n = 76) it does not mean the death of the person. The variables related to the correct knowledge of BD are age (P = .007) and marital status (P = .028), with age persisting in the multivariate study (odds ratio, 1.036; P = .008). There is no objective relationship with the attitude toward organ donation. Thus, 60% of those who know the concept are in favor of donating (n = 61), and 59% of those who do not know it are in favor (n = 210; P = .813). CONCLUSIONS: The BD concept is little known among Ecuadorians residing in Spain, and it is not associated with the attitude toward donation.

RESUMO

INTRODUCTION: New transplant-related therapies such as xenotransplantation of solid cells, tissues, and organs are still poorly understood, especially in countries without preclinical xenotransplantation programs. OBJECTIVE: Analyze the attitude toward xenotransplantation among the population of Santiago de Cuba. METHOD: Type of study. Cross-sectional observational study. SAMPLE: Random sampling of 455 individuals residing in Santiago de Cuba. Assessment instrument. Validated questionnaire of attitude toward the xenotransplant, "PCID-XenoTx-Ríos." Field work. Random selection based on stratification. Anonymous and self-administered completion. RESULTS: A total of 49.9% would accept a solid organ xenotransplant if they needed it and the results were similar to those currently obtained with human organs, 27.5% have doubts, and the remaining 22.6% would not accept it. They are presented as statistically significant variables (P < .05): level of studies; comment with the family about the donation; opinion of a partner; religion; opinion of religion; performing prosocial activities; attitude toward donation; previous relationship with the organ donation and transplant; favorable attitude toward live kidney donation. In the multivariate analysis, the following persist: 1. level of university studies: odds ratio (OR) = 5.076; 2. not having a partner: OR = 5.154; 3. belonging to another religion: OR = 2.061; 4. favorable attitude toward organ donation: OR = 5; and 5. favorable attitude toward living donation: OR = 3.759. CONCLUSIONS: The population of Santiago de Cuba is less sensitized toward xenotransplantation, possibly due to ignorance of the issue due to lack of preclinical trials in their countries.

RESUMO

INTRODUCTION: Puerto Rican and Cuban populations constitute the largest immigrant groups in Florida. This leads to an increase in their involvement in the organ donation and transplantation process (ODT); however, there is very little understanding about their attitude toward and knowledge of related key aspects such as brain death (BD). OBJECTIVE: Analyze knowledge of the BD concept among the Puerto Rican population residing in Florida. MATERIAL AND METHODS: The population under study is born in Puerto Rico and residing in Florida. Inclusion criteria was the population over 15 years stratified by age and sex. The assessment instrument was a validated questionnaire of attitude toward donation and organ transplantation "PCID-DTO-Ríos." A random selection of people was surveyed according to stratification. Support from immigration assistance associations in Florida was needed to locate potential respondents. Survey completion was anonymous and self-administered. RESULTS: Of the 259 respondents, 35% (n = 90) know the BD concept and consider it the death of an individual, 44% (n = 113) do not know it, and 21% (n = 56) do not consider them death. Variables significantly related to the correct knowledge of BD are as follows: sex (P = .012); marital status (P = .043); and couple's opinion (P = .001) and religion (P < .001). In the multivariate analysis, the variables that persist as significant are being married (odds ratio [OR] = 5.231; P = .002); to know the organ donation and transplantation couple attitude as favorable (OR = 4.819; P = .001) and not being Catholic (OR = 4.090; P < .001). CONCLUSIONS: Only one third of the Puerto Rican population residing in Florida knows the concept of BD and accepts it as the death of a person.

RESUMO

INTRODUCTION: The population of Nicaraguan immigrants is growing in North America; however, they have been little analyzed concerning their attitude toward donation and organ transplantation. OBJECTIVE: To analyze the attitude toward the different types of organ donation among the Nicaraguan population residing in Florida. METHODS: Study population. Nicaraguan population residing in Florida (USA). INCLUSION CRITERIA: Population sample over 15 years stratified by age and sex. Instrument valuation. Attitude questionnaires toward organ donation for transplantation "PCID-DTO-Ríos," "PCID-DVR-Ríos," and "PCID-XenoTx-Ríos." Setting for the study. Random selection of people to be surveyed according to stratification. The assistance of immigrant support associations in Florida was required to locate respondents. RESULTS: Sample composed of 89 participants. In the attitude toward donation of one's own organs after death, 22% (n = 20) were in favor, 41% (n = 36) were against, and 37% (n = 33) were undecided. Regarding the donation of living related organs, 76% were in favor (n = 68), 10% were against (n = 9), and 14% were undecided (n = 12). Finally, regarding attitudes toward the acceptance of organ xenotransplantation, if the results were similar to those obtained with human organs, they were not in favor, with 72% (n = 64) against and 28% (n = 25) doubtful. CONCLUSIONS: The attitude of the Nicaraguan population residing in Florida toward different types of organ donation is unfavorable.
