Ebola Virus-Specific Neutralizing Antibody Persists at High Levels in Survivors 2 Years After Resolution of Disease in a Sierra Leonean Cohort.

Ebola virus (EBOV) infection results in Ebola virus disease (EVD), an often severe disease with a nonspecific presentation. Since its recognition, periodic outbreaks of EVD continue to occur in sub-Saharan Africa. The 2013-2016 West African EVD outbreak was the largest recorded, resulting in a substantial cohort of EVD survivors with persistent health complaints and variable immune responses. In this study, we characterize humoral immune responses in EVD survivors and their contacts in Eastern Sierra Leone. We found high levels of EBOV IgG in EVD survivors and lower yet substantial antibody levels in household contacts, suggesting subclinical transmission. Neutralizing antibody function was prevalent but variable in EVD survivors, raising questions about the durability of immune responses from natural infection with EBOV. Additionally, we found that certain discrete symptoms-ophthalmologic and auditory-are associated with EBOV IgG seropositivity, while an array of symptoms are associated with the presence of neutralizing antibody.

Combined Endoscopic Robotic Surgery for Complex Colon Polyps.

BACKGROUND: Combined endoscopic robotic surgery is a surgical technique that modifies traditional endoscopic laparoscopic surgery with robotic assistance to aid in the removal of complex colonic polyps. This technique has been described in the literature but lacks patient follow-up data. OBJECTIVE: This study aimed to evaluate the safety and outcomes of combined endoscopic robotic surgery. DESIGN: A retrospective review of a prospective database. SETTING: East Jefferson General Hospital, Metairie, Louisiana. PATIENTS: Ninety-three consecutive patients who underwent combined endoscopic robotic surgery from March 2018 to October 2021 were included in the study. MAIN OUTCOME MEASURES: Operative time, intraoperative complication, 30-day postoperative complication, hospital length of stay, and follow-up pathology report results were the main outcome measures. RESULTS: Combined endoscopic robotic surgery was completed in 88 of 93 participants (95%). Among the 88 participants who completed combined endoscopic robotic surgery, the average age was 66 years (SD = 10), BMI was 28.8 kg/m 2 (SD = 6), and history of previous abdominal surgeries was 1 (SD = 1). Median operative time was 72 minutes (range, 31-184 minutes) and polyp size was 40 mm (range, 5-180 mm). The most common polyp locations were the cecum, ascending colon, and transverse colon (31%, 28%, 25%). Pathology mainly demonstrated tubular adenoma (76%). Data on 40 patients who underwent follow-up colonoscopy were available. The average follow-up time was 7 months (range, 3-22 months). One patient (2.5%) had polyp recurrence at the resection site. LIMITATIONS: Limitations for our study include a lack of randomization and follow-up rate to assess for recurrence. The low compliance rate may be due to procedure cancelations/difficulty scheduling because of changing coronavirus disease 2019 guidelines. CONCLUSIONS: Compared to literature-reported statistics for its laparoscopic counterpart, combined endoscopic robotic surgery was associated with decreased operation times and resection site polyp recurrence.

Esta técnica está previamente descrita en la literatura, pero carece de datos de seguimiento de los pacientes.OBJETIVO:Evaluar la seguridad y los resultados de la cirugía robótica endoscópica combinada.DISEÑO:Revisión retrospectiva de una base de datos prospectiva.AJUSTE:Hospital General East Jefferson, Metairie LouisianaPACIENTES:Noventa y tres pacientes consecutivos y sometidos a cirugía robótica endoscópica combinada por un solo cirujano colorrectal desde marzo de 2018 hasta octubre de 2021.PRINCIPALES MEDIDAS DE RESULTADO:Tiempo operatorio, complicación intraoperatoria, complicación posoperatoria a los 30 días, duración de la estancia hospitalaria y resultados del informe patológico de seguimiento.RESULTADOS:La cirugía robótica endoscópica combinada se completó en 88 de 93 (95%). Entre los 88 participantes que completaron la cirugía robótica endoscópica combinada, la edad promedio fue de 66 años (desviación estándar = 10), índice de masa corporal de 28,8 (desviación estándar = 6) y el historial de cirugías abdominales previas de 1 (desviación estándar = 1). La mediana del tiempo operatorio y el tamaño de los pólipos fueron 72 minutos (rango 31-184 minutos) y 40 milímetros (rango 5-180 milímetros), respectivamente. Las ubicaciones de pólipos más comunes fueron el ciego, colon ascendente y transverso (31%, 28%, 25%). La patología demostró principalmente adenoma tubular (76%). Los datos de 40 pacientes sometidos a una colonoscopia de seguimiento estaban disponibles. El tiempo medio de seguimiento fue de 7 meses (rango 3-22 meses). Un paciente (2,5%) presentó recurrencia polipoidea en el sitio de resección.LIMITACIONES:Las limitaciones de nuestro estudio incluyeron la falta de aleatorización y la tasa de seguimiento para evaluar la recurrencia. La baja tasa de seguimiento puede deberse a la renuencia del paciente en hacerse una colonoscopia o cancelaciones de procedimientos por la dificultad para programar debido a cambios de COVID-19.CONCLUSIÓN:En comparación con las estadísticas reportadas en la literatura para su contraparte laparoscópica, la cirugía robótica endoscópica combinada se asoció con reducción en tiempos de operación y recurrencia de pólipos en el sitio de resección.

GERD-screening before bariatric surgery: the predictive value of the GERD-HRQL questionnaire score compared with preoperative EGD findings.

BACKGROUND: There is an ongoing debate on how to best identify patients with gastroesophageal reflux disease (GERD) before bariatric surgery. The value of routine preoperative esophagogastroduodenoscopy (EGD) is questioned, and patient reported symptoms are commonly used for screening. The goal of this study is to determine if patient reported symptoms using a validated questionnaire correlate with preoperative EGD findings. METHODOLOGY: A prospective cohort study at a single institution was performed. Patients undergoing bariatric surgery between December 2020 and March 2023 were required to report symptoms of reflux by completing a preoperative GERD. Health-Related Quality of Life (GERD-HRQL) questionnaire and undergo a mandatory preoperative screening EGD. Patients were stratified into two cohorts: (group A) asymptomatic (score = 0) and (group B) symptomatic (score > 0). Statistical analysis was conducted using Pearson's chi-squared test and Wilcoxon rank-sum test in RStudio version 4.2.2. The predictive value of the GERD-HRQL score was analyzed using Areas Under the Curve (AUC; AUC = 0.5 not predictive, 0.5 < AUC ≥ 6 poor prediction & AUC > 0.9 excellent prediction) calculated from Receiver Operating Characteristic (ROC) curves. RESULTS: 200 patients were included; median age was 42.0 years (IQR 36.0 to 49.2). There were 79 patients (39.5%) in Group A and 121 patients (60.5%) in Group B. There was no difference in the frequency esophagitis (27.8% vs 32.2%, p = 0.61) or hiatal hernias (49.4% vs 47.1%, p = 0. 867) between group A and group B, respectively. ROC analysis revealed that the total GERD HRQL scores, heartburn only scores and regurgitation only scores, were poor predictors of esophagitis found on EGD (AUC 0.52, 0.53, 0.52), respectively. In asymptomatic patients, higher BMI was significantly associated with esophagitis (OR 1.15, 95% CI 1.06-1.27, p = 0.002). CONCLUSION: Symptoms, identified through the GERD-HRQL questionnaire, are a poor indicator of esophagitis or its severity in patients undergoing workup for bariatric surgery. Therefore, liberal screening upper endoscopy is recommended for pre-bariatric surgery patients to guide appropriate procedure selection.

Kratom: The safe legal high?

Illicit drugs are used to produce a sense of euphoria in the user. Like marijuana, kratom is a plant-based substance. The leaves of the Mitragyna speciosa tree were used to treat mild medical conditions in Thailand and Malaysia as a stimulant in low doses, and sedative and analgesic at high doses. Over recent years, kratom gained popularity as a recreational drug among younger individuals in Southeast Asia due to its availability as a cheap and easily assessable substance with euphoric effects. This trend has rapidly made its way to the West. Unlike marijuana, in the United States kratom's use as an inexpensive herbal recreational "supplement" is poorly popularized. However, emerging reports garnished from use as a recreational drug reveals a potential health hazard. Seizures and neurological consequences have been reported from kratom abuse. Complex pharmacokinetics place patients at further risk of side effects and drug interactions. Still, individuals can legally purchase kratom at stores and through online distributers in capsule form or as teas, powders, and extracts under the veil of a harmless herbal remedy. Without United States Food and Drug Administration oversight, kratom has a high potential for abuse and without regulatory control threatens public safety.

Recurrent seizures from chronic kratom use, an atypical herbal opioid.

Kratom is an herbal compound that has been used as a recreational drug though is not regulated by the Food and Drug Administration. We report a 19-year-old male with recurrent seizures that developed during daily Kratom abuse as a self-treatment for anxiety. Following recurrent focal impaired awareness seizures in addition to generalized tonic-clonic seizures, he was begun on anti-seizure drugs. Seizures subsided after completing rehabilitation. Brain MRI at 29 months revealed bilaterally symmetric T1-hyperintensity in globus pallidus, subthalamic nuclei, and cerebral peduncles. Our case suggests Kratom abuse may be associated with structural brain lesions on MRI and symptomatic focal epilepsy.
