RESUMO

In this Viewpoint, we provide an overview of the worsening trend of traumatic injuries across the United States-Mexico border after its recent fortification and height extension to 30-feet. We further characterize the international factors driving migration and the current U.S. policies and political climate that will allow this public health crisis to progress. Finally, we provide recommendations involving prevention efforts, effective resource allocation, and advocacy that will start addressing the humanitarian and economic consequences of current U.S. border policies and infrastructure.

RESUMO

BACKGROUND: The San Diego-Mexico border wall height extension is associated with increased traumatic injuries and related costs after wall falls. We report previous trends and a neurological injury type not previously associated with border falls: blunt cerebrovascular injuries (BCVIs). METHODS: In this retrospective cohort study, patients who presented to the UC San Diego Health Trauma Center for injuries from border wall falls from 2016 to 2021 were considered. Patients were included if they were admitted before (January 2016 to May 2018) or after (January 2020 to December 2021) the height extension period. Patient demographics, clinical data, and hospital stay data were compared. RESULTS: We identified 383 patients, 51 (68.6% male; mean age, 33.5 years) in the pre-height extension cohort and 332 (77.1% male; mean age, 31.5 years) in the post-height extension cohort. There were 0 and 5 BCVIs in the pre- and post-height extension groups, respectively. BCVIs were associated with increased injury severity scores (9.16 vs. 31.33; P < 0.001), longer intensive care unit lengths of stay (median, 0 days; [interquartile range (IQR), 0-3 days]; vs. median, 5 days [IQR, 2-21 days]; P = 0.022), and increased total hospital charges (median, $163,490 [IQR, $86,578-$282,036]; vs. median, $835,260 [IQR, $171,049-$1,933,996]; P = 0.048). Poisson modeling found BCVI admissions were 0.21 (95% confidence interval, 0.07-0.41; P = 0.042) per month higher after the height extension. CONCLUSIONS: We review the injuries correlating with the border wall extension and reveal an association with rare, potentially devastating BCVIs that were not seen before the border wall modifications. These BCVIs and associated morbidity shed light on the trauma increasingly found at the southern U.S. border, which could be informative for future infrastructure policy decisions.

RESUMO

Introducción: Frente a pandemia producida por el SARS-CoV-2, el gobierno peruano implementó diversas medidas como el cierre temporal de los establecimientos del primer nivel de atención y el sistema sanitario implementó diversas políticas y estrategias; una de ellas, fue la creación e implementación del proyecto del Sistema de Entrega de Medicamentos a Pacientes Crónicos (SIENMECRO). Objetivo: Describir el proceso de creación e implementación del proyecto SIENMECRO. Métodos: Investigación cualitativa de tipo estudio de caso que implicó la revisión de la documentación existente como textos y videos y, realización de entrevistas en profundidad a funcionarios y colaboradores involucrados desde la elaboración de la propuesta del SIENMECRO. Resultados: El proyecto SIENMECRO surge como una iniciativa positiva con la aspiración de impulsar un sistema integrado de salud que aborde la realidad sanitaria desde los determinantes sociales de la salud, debido a las dificultades de los pacientes para acudir a sus controles y recibir su tratamiento. A pesar de que no se contó con un plan integral de implementación y control del proyecto, fue fundamental para cubrir la necesidad de atención sanitaria a un segmento vulnerable de la población, evitando su traslado y preservando la salud de las personas más susceptibles de padecer complicaciones por la infección por COVID-19. Conclusiones: Es una iniciativa donde el sistema sanitario toma un rol más proactivo en beneficio de la población, implementando el uso de las tecnologías de información y comunicación en la atención de salud, articulando con los diversos prestadores y acercando los servicios a los ciudadanos más vulnerables.


Introduction: Faced with the pandemic produced by SARS-CoV-2, the Peruvian government implemented several measures such as the temporary closure of primary care facilities and the health system implemented various policies and strategies; one of them was to create and implement the Drug Delivery System for Chronic Patients (SIENMECRO) project. Objective: To describe the creation and implementation process of SIENMECRO project. Methods: Qualitative case study that involved reviewing existing documentation such as texts and videos and conducting in-depth interviews with officials and collaborators involved since the preparation of SIENMECRO proposal. Results: SIENMECRO project emerges as a positive initiative with the aspiration of promoting an integrated health system that addresses the health reality from the social determinants of health, due to patients' difficulties to go to their controls and to receive their treatment. Although there was no comprehensive plan for the implementation and control of the project, it was essential to cover the need for health care for a vulnerable segment of the population, avoiding their transfer and preserving the health of the people most likely to suffer complications from COVID-19 infection. Conclusions: It is an initiative where the health system takes a more proactive role for the benefit of the population, implementing the use of technology of the information and communication in health care, articulating with the various providers and bringing services closer to the most vulnerable citizens.

RESUMO

OBJECTIVE: The aim of this study was to investigate the impact of the US-Mexico border wall height extension on traumatic brain injuries (TBIs) and related costs. METHODS: In this retrospective cohort study, patients who presented to the UC San Diego Health Trauma Center for injuries from falling at the border wall between 2016 and 2021 were considered. Patients in the pre-height extension period (January 2016-May 2018) were compared with those in the post-height extension period (January 2020-December 2021). Demographic characteristics, clinical data, and hospital charges were analyzed. RESULTS: A total of 383 patients were identified: 51 (0 TBIs, 68.6% male) in the pre-height extension cohort and 332 (14 TBIs, 77.1% male) in the post-height extension cohort, with mean ages of 33.5 and 31.5 years, respectively. There was an increase in the average number of TBIs per month (0.0 to 0.34) and operative TBIs per month (0.0 to 0.12). TBIs were associated with increased Injury Severity Score (8.8 vs 24.2, p < 0.001), median (IQR) hospital length of stay (5.0 [2-11] vs 8.5 [4-45] days, p = 0.03), and median (IQR) hospital charges ($163,490 [$86,369-$277,918] vs $243,658 [$136,769-$1,127,920], p = 0.04). TBIs were normalized for changing migration rates on the basis of Customs and Border Protection apprehensions. CONCLUSIONS: This heightened risk of intracranial injury among vulnerable immigrant populations poses ethical and economic concerns to be addressed regarding border wall infrastructure.

RESUMO

El confinamiento a consecuencia de la Covid-19 ha ocasionado cambios en los estilos de vida de los estudiantes, especialmente en la práctica de actividad física (AF), ya que la mayoría permanecieron en sus casas con limitaciones para desarrollar AF. Objetivo: Determinar los niveles de actividad física de los estudiantes de una universidad privada antes y durante el confinamiento por la pandemia de la Covid-19. Material y métodos: Investigación cuantitativa, observacional de corte transversal comparativa, se invitó vía e-mail a todos los estudiantes de pregrado de la Facultad de Salud Pública y Administración (N=161). Para medir el nivel de AF de antes y durante se aplicó el cuestionario IPAQ versión corta mediante Google Forms. Resultados: La tasa de respuesta fue 56,5% (n=91). Al comparar AF antes y durante la pandemia, la cantidad de alumnos con nivel alto de AF disminuyó en 55,6% y en nivel moderado cayó en 10,9%, mientras que en nivel bajo aumentó en 111,1%. En relación con la frecuencia, la cantidad de alumnos que realizaban AF según las cifras recomendadas de la OMS, disminuyó de 36 a 23 (36,1%). Conclusiones: El confinamiento tuvo consecuencias negativas tanto en el nivel y frecuencia de AF según lo recomendado por OMS.


SUMMARY COVID-19 lockdown has changed student's lifestyle, especially the physical activity (PA) as many students remained at home with limitations to perform PA. Objective: To determine the level of physical activity of private university students before and during lockdown due to COVID-19 pandemic. Methods: A cross-sectional study was performed including all pre-graduated students of the Public Health and Administration Faculty (N=161) invited by e-mail. To measure the level of PA before and during the lockdown, a short version of the questionnaire IPAQ was applied via Google Forms. Results: The answer rate was 56.5% (n=91). A significant reduction in PA before and during lockdown was observed, values were 55.6%, 10.9% and 11.1% for the high, intermediate, and low levels of PA. The number of students that performed PA based on WHO's recommendation decreased from 36 to 23 (36.1%). Conclusions: The lockdown impacted negatively in the intensity and frequency of PA based on WHO's recommendations.

RESUMO

BACKGROUND: The recent San Diego-Mexico border wall height extension has resulted in an increased injury risk for unauthorized immigrants falling from greater heights. However, the effects of the border wall extension on frequency and morbidity of spinal injuries and related economic costs have yet to be highlighted. METHODS: We retrospectively compared two cohorts who presented to the UC San Diego Health Trauma Center for border wall falls: pre-height extension (12 patients; January 2016-May 2018), and post-height extension (102 patients; January 2020-December 2021). Patients presented during border wall construction (June 2018-December 2019) were excluded. Demographics, clinical data and hospital costs were collected. Spinal injuries were normalized using Customs and Border Protection apprehensions. Costs were adjusted for inflation using the 2021 medical care price index. RESULTS: The increase in spine injuries per month (0.8-4.25) and operative spine injuries per month (0.3- 1.7) was statistically significant (P < 0.001). Increase in median length of stay from 6 [interquartile range (IQR) 2-7] to 9 days (IQR 6-13) was statistically significant (P = 0.006). Median total hospital charges increased from $174 660 to $294 421 and was also significant (P < 0.001). CONCLUSION: The data support that the recent San Diego-Mexico border wall extension is correlated with more frequent, severe and costly spinal injuries. This current infrastructure should be re-evaluated as border-related injuries represent a humanitarian and public health crisis.

RESUMO

BACKGROUND: Isolated spinal artery aneurysms are extremely rare, and their pathogenesis, clinical presentation, and treatment strategies are poorly established. We report only the second case of a patient with an isolated posterior spinal aneurysm and concurrent left thalamic infarct and review the literature to help clarify treatment strategies of isolated spinal aneurysms. CASE PRESENTATION: A 49-year-old patient presented with acute onset walking difficulty followed by diaphoresis, back and abdominal pain, and paraplegia. Imaging was notable for a hemorrhagic spinal lesion with compression at T12 through L4 and an acute left thalamic infarct. Surgical exploration revealed an isolated posterior spinal artery aneurysm. The aneurysm was surgically resected and the patient had partial recovery six months post-operatively. CONCLUSIONS: Isolated posterior spinal artery aneurysms of the thoracolumbar region are rare lesions that commonly present with abdominal pain, radiating back pain, and lower extremity weakness. Imaging may not provide a definitive diagnosis. The three primary treatment strategies are conservative management, endovascular treatment, or surgical resection. In patients with symptomatic cord compression, immediate surgical intervention is indicated to preserve neurologic function. In all other cases, the artery size, distal flow, morphology, and location may guide management.

RESUMO

BACKGROUND: The treatment of pseudarthrosis after transforaminal lumbar interbody fusion (TLIF) can be challenging, particularly when anterior column reconstruction is required. There are limited data on TLIF cage removal through an anterior approach. OBJECTIVE: To assess the safety and efficacy of anterior lumbar interbody fusion (ALIF) as a treatment for pseudarthrosis after TLIF. METHODS: ALIFs performed at a single academic medical center were reviewed to identify cases performed for the treatment of pseudarthrosis after TLIF. Patient demographics, surgical characteristics, perioperative complications, and 1-yr radiographic data were collected. RESULTS: A total of 84 patients were identified with mean age of 59 yr and 37 women (44.0%). A total of 16 patients (19.0%) underwent removal of 2 interbody cages for a total of 99 implants removed with distribution as follows: 1 L2/3 (0.9%), 6 L3/4 (5.7%), 37 L4/5 (41.5%), and 55 L5/S1 (51.9%). There were 2 intraoperative venous injuries (2.4%) and postoperative complications were as follows: 7 ileus (8.3%), 5 wound-related (6.0%), 1 rectus hematoma (1.1%), and 12 medical complications (14.3%), including 6 pulmonary (7.1%), 3 cardiac (3.6%), and 6 urinary tract infections (7.1%). Among 58 patients with at least 1-yr follow-up, 56 (96.6%) had solid fusion. There were 5 cases of subsidence (6.0%), none of which required surgical revision. Two patients (2.4%) required additional surgery at the level of ALIF for pseudarthrosis. CONCLUSION: ALIF is a safe and effective technique for the treatment of TLIF cage pseudarthrosis with a favorable risk profile.

RESUMO

OBJECTIVE: Anterior lumbar interbody fusion (ALIF) is a powerful technique that provides wide access to the disc space and allows for large lordotic grafts. When used with posterior spinal fusion (PSF), the procedures are often staged within the same hospital admission. There are limited data on the perioperative risk profile of ALIF-first versus PSF-first circumferential fusions performed within the same hospital admission. In an effort to understand whether these procedures are associated with different perioperative complication profiles, the authors performed a retrospective review of their institutional experience in adult patients who had undergone circumferential lumbar fusions. METHODS: The electronic medicals records of patients who had undergone ALIF and PSF on separate days within the same hospital admission at a single academic center were retrospectively analyzed. Patients carrying a diagnosis of tumor, infection, or traumatic fracture were excluded. Demographics, surgical characteristics, and perioperative complications were collected and assessed. RESULTS: A total of 373 patients, 217 of them women (58.2%), met the inclusion criteria. The mean age of the study cohort was 60 years. Surgical indications were as follows: degenerative disease or spondylolisthesis, 171 (45.8%); adult deformity, 168 (45.0%); and pseudarthrosis, 34 (9.1%). The majority of patients underwent ALIF first (321 [86.1%]) with a mean time of 2.5 days between stages. The mean number of levels fused was 2.1 for ALIF and 6.8 for PSF. In a comparison of ALIF-first to PSF-first cases, there were no major differences in demographics or surgical characteristics. Rates of intraoperative complications including venous injury were not significantly different between the two groups. The rates of postoperative ileus (11.8% vs 5.8%, p = 0.194) and ALIF-related wound complications (9.0% vs 3.8%, p = 0.283) were slightly higher in the ALIF-first group, although the differences did not reach statistical significance. Rates of other perioperative complications were no different. CONCLUSIONS: In patients undergoing staged circumferential fusion with ALIF and PSF, there was no statistically significant difference in the rate of perioperative complications when comparing ALIF-first to PSF-first surgeries.

RESUMO

BACKGROUND: The spine is the most common site of bony metastases. Associated pathological fractures can result in pain, neurological deficit, biomechanical instability, and deformity. OBJECTIVE: To present a minimally invasive technique for indirect decompression by ligamentotaxis in pathological fractures. METHODS: A minimally invasive approach was utilized to perform percutaneous pedicle screw fixation in patients who required stabilization for pathological fractures. Preoperative and postoperative computed tomography and magnetic resonance imaging were used to compare spinal canal area and midsagittal canal diameter. RESULTS: Two patients with newly diagnosed pathological fractures underwent minimally invasive treatment. Each presented with minimal epidural disease and a chief complaint of intractable back pain without neurological deficit. They underwent minimally invasive pedicle screw fixation with indirect decompression by ligamentotaxis. In each case, postoperative imaging demonstrated an increase in spinal canal area and midsagittal canal diameter by an independent neuroradiologist. There were no perioperative complications, and each patient was neurologically stable without evidence of hardware failure at their 5- and 6-mo follow-up visits. CONCLUSION: Minimally invasive percutaneous fixation can be used to stabilize pathological fractures and provide indirect decompression by ligamentotaxis. This procedure is associated with minimal blood loss, low morbidity, and rapid initiation of radiation therapy. Only patients with minimal epidural disease, stenosis caused primarily by bony retropulsion, and mild-to-moderate deformity should be considered candidates for this approach.

RESUMO

OBJECTIVE: Anterior approaches to the lumbar spine provide wide exposure that facilitates placement of large grafts with high fusion rates. There are limited data on the effects of obesity on perioperative complications. METHODS: Data from consecutive patients undergoing anterior lumbar interbody fusion (ALIF) from 2007 to 2016 at a single academic center were analyzed. The primary outcome was any perioperative complication. Complications were divided into those occurring intraoperatively and those occurring postoperatively. Multivariate logistic regression was used to assess the association of obesity and other variables with these complications. An estimation table was used to identify a body mass index (BMI) threshold associated with increased risk of postoperative complication. RESULTS: A total of 938 patients were identified, and the mean age was 57 years; 511 were females (54.5%). The mean BMI was 28.7 kg/m2, with 354 (37.7%) patients classified as obese (BMI ≥ 30 kg/m2). Forty patients (4.3%) underwent a lateral transthoracic approach, while the remaining 898 (95.7%) underwent a transabdominal retroperitoneal approach. Among patients undergoing transabdominal retroperitoneal ALIF, complication rates were higher for obese patients than for nonobese patients (37.0% vs 28.7%, p = 0.010), a difference that was driven primarily by postoperative complications (36.1% vs 26.0%, p = 0.001) rather than intraoperative complications (3.2% vs 4.3%, p = 0.416). Obese patients had higher rates of ileus (11.7% vs 7.2%, p = 0.020), wound complications (11.4% vs 3.4%, p < 0.001), and urinary tract infections (UTI) (5.0% vs 2.5%, p = 0.049). In a multivariate model, age, obesity, and number of ALIF levels fused were associated with an increased risk of postoperative complication. An estimation table including 19 candidate cut-points, odds ratios, and adjusted p values found a BMI ≥ 31 kg/m2 to have the highest association with postoperative complication (p = 0.012). CONCLUSIONS: Obesity is associated with increased postoperative complications in ALIF, including ileus, wound complications, and UTI. ALIF is a safe and effective procedure. However, patients with a BMI ≥ 31 kg/m2 should be counseled on their increased risks and warrant careful preoperative medical optimization and close monitoring in the postoperative setting.

RESUMO

STUDY DESIGN: Case-control study. OBJECTIVES: To analyze the microbial flora in surgical spine infections and their antibiotic resistance patterns across time and determine the correlation between vancomycin application in the wound and vancomycin-resistant microbes. SUMMARY OF BACKGROUND DATA: Prior studies show a reduction in surgical site infections with intrawound vancomycin placement. No data are available on the potential negative effects of this intervention, in particular, whether there would be a resultant increase in vancomycin-resistant organisms or bacterial resistance profiles. METHODS: All culture-positive surgical site infections at a single institution were analyzed from 2007 to 2017. Each bacterium was assessed independently for resistance patterns. The two-tailed Fisher exact test was used to determine the correlation between vancomycin application and the presence of vancomycin-resistant bacteria, polymicrobial infections, or gram-negative bacterial infections. RESULTS: One hundred and eight bacteria were isolated from 113 surgical site infections from 2007 to 2017. The most common organisms were staphylococcus with varying resistance patterns and Escherichia coli. Vancomycin-resistant Enterococcus faecium was isolated in three infections. Out of the 4,878 surgical cases from 2011 to 2017, vancomycin was placed in 48.3%, and no vancomycin in 51.7%. There were 33 infections (1.4%) in the vancomycin group and 20 infections (0.8%) in the no-vancomycin group (χ2 = 0.0521). There was no correlation between vancomycin application in the wound and vancomycin-resistant microbes (χ2 = 0.2334) and polymicrobial infections (χ2 = 0.1328). There was an increased rate of gram-negative organisms in infections after vancomycin application in the wound versus no vancomycin (χ2 = 0.0254). CONCLUSIONS: Topical vancomycin within the surgical site is not correlated with vancomycin-resistant bacteria. However, there was an increased incidence of gram-negative organisms in infections after vancomycin application in the wound versus no vancomycin. Continued surveillance with prospectively collected randomized data is necessary to better understand bacterial evolution against current antimicrobial techniques. LEVEL OF EVIDENCE: Level III.

RESUMO

This analysis presents a comprehensive description of malaria burden and risk factors in Peruvian Amazon villages where malaria transmission is hypoendemic. More than 9000 subjects were studied in contrasting village settings within the Department of Loreto, Peru, where most malaria occurs in the country. Plasmodium vivax is responsible for more than 75% of malaria cases; severe disease from any form of malaria is uncommon and death rare. The association between lifetime malaria episodes and individual and household covariates was studied using polychotomous logistic regression analysis, assessing effects on odds of some vs. no lifetime malaria episodes. Malaria morbidity during lifetime was strongly associated with age, logging, farming, travel history, and living with a logger or agriculturist. Select groups of adults, particularly loggers and agriculturists acquire multiple malaria infections in transmission settings outside of the main domicile, and may be mobile human reservoirs by which malaria parasites move within and between micro-regions within malaria endemic settings. For example, such individuals might well be reservoirs of transmission by introducing or reintroducing malaria into their home villages and their own households, depending on vector ecology and the local village setting. Therefore, socio-demographic studies can identify people with the epidemiological characteristic of transmission risk, and these individuals would be prime targets against which to deploy transmission blocking strategies along with insecticide treated bednets and chemoprophylaxis.
