Vestibular evaluation with video head impulse test in pediatric cochlear implant patients / Evaluación vestibular con videoimpulso cefálico en pacientes pediátricos con implante coclear

Abstract Background: The cochlear implant (CI) is effective for rehabilitating patients with severe to profound sensorineural hearing loss. However, its placement and use have been associated with various complications, such as those affecting the vestibular system. The objective of this study was to compare vestibular function using the video head impulse test (vHIT) in pediatric patients before and after CI placement. Methods: A descriptive and retrospective study was conducted. The outcomes of 11 pediatric patients of both sexes with a history of profound hearing loss were evaluated. The results of vestibular-ocular reflex (VOR) gain, saccades, asymmetry, Pérez Rey (PR) index, and VOR/saccade ratio for both ears obtained by the vHIT test before and after CI placement were compared. Results: Of the 11 patients evaluated, the VOR gain showed that 81.8% had normal function, 18.2% had hypofunction, and no patients had hyperfunction before implantation. No statistically significant differences were found when compared with post-implant off and post-implant on conditions (p > 0.05). The extracted variables, asymmetry, PR index, and the VOR/saccades ratio also showed no statistically significant differences between the pre- and post-implant conditions, whether off or on. Conclusions: The vestibular function of pediatric patients did not show significant changes before and after CI placement. The vHIT test is a valuable tool for assessing vestibular function and could be considered a criterion for surgical and rehabilitation decisions in patients undergoing CI placement.

Resumen Introducción: El implante coclear es un dispositivo eficaz para la rehabilitación de pacientes con hipoacusia neurosensorial severa a profunda. Sin embargo, su colocación y uso se ha asociado a diversas complicaciones, entre ellas a nivel del sistema vestibular. El objetivo del presente estudio fue comparar la función vestibular mediante la prueba de videoimpulso cefálico (vHIT) de pacientes pediátricos antes y después de la colocación del implante coclear. Métodos: Se llevó a cabo un estudio descriptivo y retrospectivo. Se evaluaron los resultados de 11 pacientes pediátricos de ambos sexos con antecedente de hipoacusia profunda. Se compararon los resultados de ganancia del VOR, sacadas, asimetría, índice PR así como la relación VOR/sacadas para ambos oídos obtenidos mediante la prueba vHIT antes y después de la colocación del implante coclear. Resultados: De los 11 pacientes evaluados, la ganancia del VOR mostró que el 81.8% tenía normofunción, 18.2% hipofunción y ningún paciente hiperfunción antes del implante. Al compararlo con la ganancia post implante apagado y post implante encendido no se encontraron diferencias estadísticamente significativas (p > 0.05). Las variables sacadas, asimetría, índice PR así como la relación VOR/sacadas tampoco mostraron diferencias estadísticamente significativas entre las condiciones pre y pos implante ya sea apagado o encendido. Conclusiones: La función vestibular de pacientes pediátricos no mostró cambios significativos previo y posterior a la colocación del implante coclear. La prueba vHIT es una herramienta útil que permite evaluar la función vestibular y que podría considerarse como criterio para tomar decisiones quirúrgicas en pacientes que se encuentran en protocolo para implante coclear.

Predators of the sea urchin Diadema mexicanum (Diadematoida: Diadematidae) at the Eastern Tropical Pacific coral reefs / Depredadores del erizo de mar Diadema mexicanum (Diadematoida: Diadematidae) en los arrecifes de coral del Pacífico Tropical Oriental

Abstract Introduction: The coral reefs of Isla del Coco National Park are some of the most pristine ecosystems on Earth. The sea urchin Diadema mexicanum (Diadematoida: Diadematidae) is a common inhabitant with a pivotal role in the ecology of this unique ecosystem. Objective: In this study, we identified the predominant predators of D. mexicanum and estimated the predatory consumption rates. We also determined predation rates at different sea urchin sizes and at sites with contrasting refuge availability. Methods: We use field video recording observations and tethering experiments. Results: The balistid Sufflamen verres and the labrid Bodianus diplotaenia were identified as predators of small and medium size D. mexicanum; the labrids Thalassoma grammaticum and B. diplotaenia (juvenile) and the tetraodontid Arothron meleagris were attempted predators; and Canthigaster punctatissima and Holacanthus passer were scavengers. Larger sea urchins (> 30 mm) were also preyed upon during the tethering experiments. Furthermore, a clear effect of the site on survival of the different sea urchins' sizes was noted. No difference in the sea urchin predator biomass was found among sites, which highlights the importance of site complexity on survival. At high and medium complexity sites, large individuals had better survival, while at the low complexity site, there was almost no differences in survival rates among the three size classes. Our results also show that a high abundance of these predatory fishes, above 0.04 ind m-2, guarantees a low sea urchin density. Below this threshold, a higher variability in sea urchin density is observed Despite not being registered with the video recordings, lobsters were observed once preying upon a large sea urchin individual. Conclusions: This study identifies a keystone fish guild with high predation rate for Diadema in the National Park, which suggests that protective actions have positively benefited predatory fish and lobster populations.

Resumen Introducción: Los arrecifes de coral del Parque Nacional Isla del Coco son uno de los ecosistemas más prístinos de la Tierra. El erizo de mar Diadema mexicanum (Diadematoida: Diadematidae) es un habitante común con un papel ecológico esencial en este ecosistema único. Objetivo: En este estudio, identificamos los depredadores predominantes de D. mexicanum y estimamos las tasas de consumos predatorias. También determinamos las tasas predatorias de diferentes tamaños de erizo de mar en sitios con disponibilidad de refugio contrastante. Métodos: Utilizamos grabaciones de video de campo y experimentos de marcaje. Resultados: El pez ballesta Sufflamen verres y el lábrido Bodianus diplotaenia fueron identificados como depredadores de tamaños pequeños y medianos de D. Mexicanum; los lábridos Thalassoma grammaticum y B. diplotaenia (juvenil) y el tetraodóntido Arothron meleagris fueron intento de depredadores; y Canthigaster punctatissima y Holacanthus passer fueron carroñeros. Los erizos de mar de gran tamaño (> 30 mm) también fueron depredados durante el experimento de marcaje. Además, se encontró un efecto claro del sitio en la supervivencia de los diferentes tamaños de erizo de mar. No se encontraron diferencias en la biomasa de los depredadores del erizo de mar entre sitios, lo que señala la importancia de la complejidad del sitio en la supervivencia. En sitios con complejidad estructural alta y media, los individuos grandes tuvieron mejor supervivencia, mientras que en sitios de complejidad baja apenas hubo diferencias en las tasas de supervivencia entre los tres tamaños. Nuestros resultados también muestran que una alta abundancia de peces depredadores, por encima de 0.04 ind m-2, asegura bajas densidades de erizos de mar. A pesar de no ser registrado durante las grabaciones de video, se observó en una ocasión a una langosta depredando sobre un erizo de gran tamaño. Conclusiones: Este estudio identifica el grupo de peces clave con grandes tasas de depredación sobre Diadema en el Parque Nacional, lo que sugiere que las medidas de protección han beneficiado positivamente las poblaciones de peces depredadores y langostas.

Clinical application of Mimics software system to three-dimensional reconstruction to guide thoracoscopic anatomic pulmonary segmentectomy / 中国胸心血管外科临床杂志

@#Objective    To investigate the clinical effect of 3D computed tomography bronchial bronchography and angiography (3D-CTBA) and guidance of thoracoscopic anatomic pulmonary segmentectomy by Mimics software system. Methods    A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results    A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion    For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.

Diagnosis and treatment of 131 adult patients with bronchopulmonary sequestration: A retrospective analysis / 中国胸心血管外科临床杂志

@#Objective    To explore the safety and feasibility of uni-portal video-assisted thoracic surgery (VATS) for the treatment of bronchopulmonary sequestration (BPS). Methods    The clinical data of BPS patients with surgical resection in Shanghai Pulmonary Hospital from February 2010 to June 2021 were reviewed. The patients were divided into a VATS group and a thoracotomy group according to the operation method. The operation time, intraoperative blood loss, hospital stay and postoperative complication rate were compared between the two groups. The VATS group was subdivided into a uni-portal VATS group and a multi-portal VATS group for subgroup analysis. Results    Finally 131 patients were enrolled, including 62 males and 69 females with an average age of 39.3±13.2 years. There were 103 patients in the VATS group and 28 patients in the thoracotomy group. A total of 104 patients were diagnosed with left lower BPS, 26 with right lower BPS and 1 with bilateral lower BPS. The main symptom was cough (88 patients, 67.2%). There were 119 patients diagnosed by thoracic enhanced CT before operation. Compared with the thoracotomy group, the operation time was not statistically different (P=0.717), but the blood loss was less, the rate of postoperative complication was lower and hospital stay was shorter in the VATS group (P<0.05). The rate of conversion to open surgery in the uni-portal VATS group and multi-portal VATS group was 11.8% and 13.5%, respectively. Meanwhile, patients in the uni-portal VATS group had shorter operation time and postoperative hospital stay, less blood loss and lower postoperative complication rate than those in the multi-portal VATS group (P<0.05). Conclusion     In order to improve the rate of diagnosis, the lung enhanced CT scan should be selected as an optimal noninvasive method in adult suspected patients (especially those with solid cystic and solid lesions in the lower lobe). Uni-portal VATS is a safe and feasible method for BPS which can be widely promoted.

Objective:To explore the clinical efficacy of simultaneous or staged video-assisted thoracoscopic surgery (VATS) anatomic segmentectomy for bilateral double primary lung cancer (DPLC).Methods:A retrospective cohort study was conducted. The clinical data of 76 patients with bilateral DPLC who underwent VATS anatomic segmentectomy in Luzhou Traditional Chinese Medicine Hospital from February 2020 to August 2022 were retrospectively analyzed, and they were classified into the simultaneous bilateral thoracoscopic surgery group (the simultaneous group, 44 cases) and the staged thoracoscopic surgery group (the staged group, 32 cases) on the basis of the surgical methods. The intraoperative conditions, perioperative indexes and postoperative complications of the two groups were compared.Results:There were no statistically significant differences in the gender, age, pathological type,postoperative TNM staging of both groups (all P > 0.05). The anesthesia awakening time of the first and second stages of surgery in the staged group was (11±3) min and (13±4) min, which was shorter than that in the simultaneous group [(16±4) min] ( t values were 5.27 and 3.51, both P < 0.05). The number of drainage tubes placed in the simultaneous group was less than that in the sum of two stages of the staged group [(1.9±0.5) tubes vs. (2.2±0.5) tubes, t = 3.40, P = 0.001]. The duration of thoracic drainage tube retention, the postoperative total drainage flow, the days of hospitalization, the first postoperative landing time, and the total treatment cost in the first and second stages of surgery in the staged group were lower than those in the simultaneous group (all P < 0.05), while the postoperative total drainage flow, the days of hospitalization, and the total treatment cost in the sum of two stages of the staged group were higher than those in the simultaneous group (all P < 0.05). The total incidence of complications in the simultaneous group was higher than that in the staged group 1 month after surgery [18.18% (8/44) vs. 3.13% (1/32)], and the difference was statistically significant ( χ2 = 4.02, P = 0.045). The scores of activities of daily living, arterial partial pressure of oxygen, arterial partial pressure of carbon dioxide, and blood oxygen saturation in the simultaneous group were lower than those in the staged group (all P < 0.05). Conclusions:Staged VATS anatomic segmentectomy for bilateral DPLC has few complications and good ability to perform activities of daily living, whereas the treatment cost of simultaneous bilateral thoracoscopic surgery is low. Clinicians may recommend prioritizing simultaneous bilateral thoracoscopic surgery after comprehensively considering the patients ' physical and economic conditions.

Effect of metal-supported multi-sided foramen ultrafine drainage tube on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic upper lobectomy: A retrospective study in a single center / 中国胸心血管外科临床杂志

@#Objective To investigate the effect of multi-sided foramen ultrafine drainage tube with metal support on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic (VATS) upper lobectomy. Methods The clinical data of the patients who underwent uniportal VATS upper lobectomy for lung cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2021 to April 2022 were retrospectively analyzed. According to the type of ultrafine drainage tube used in the surgery, the patients were divided into a test group (using metal-supported multi-sided foramen ultrafine drainage tube) and a control group (using ordinary 12F ultrafine drainage tube). The incidence of postoperative thoracic residual cavity and operation-related data were compared between the two groups. Results A total of 200 patients were enrolled, including 126 males and 74 females, with a mean age of 57.52 years. There were 90 patients in the test group, and 110 patients in the control group. The incidence of postoperative thoracic residual cavity in the test group was lower than that in the control group (P=0.045). The differences in the postoperative bedtime, postoperative visual analogue scale, postoperative analgesic pump using time, postoperative hospitalization time, times of postoperative thoracentration and drainage, postoperative drainage time and hospitalization cost between the two groups were statistically significant (P<0.05). The incidences of postoperative lung infection, pleural effusion and atelectasis complications were lower in the test group than those in the control group (P<0.05). The differences in the preoperative anesthesia time, operation time, intraoperative bleeding and postoperative lung leakage were not statistically significant (P>0.05). Conclusion The use of multi-sided foramen ultrafine drainage tube with metal support can reduce the incidence of thoracic residual cavity after uniportal VATS upper lobectomy, and can reduce pain and economical burdens and the incidence of operation-related complications, accelerating the recovery of patients after surgery. The application of multi-sided foramen ultrafine drainage tube with metal support in uniportal VATS upper lobectomy can be widely used in the clinic.

Safety analysis of video-assisted thoracic surgery in Day Care Unit and the risk factors for delayed discharge / 中国胸心血管外科临床杂志

@#Objective To explore the perioperative safety of video-assisted thoracic surgery (VATS) in Day Care Unit and the risk factors for delayed discharge under centralized management model. Methods The patients with VATS managed by the Day Care Unit of the Drum Tower Hospital Affiliated to Nanjing University Medical School in 2021 were retrospectively collected. The patients’ postoperative data and risk factors for delayed discharge were analyzed. Results A total of 383 patients were enrolled, including 179 males and 204 females with an average age of 46.09±14.82 years. Eleven (2.87%) patients developed grade 3-4 postoperative complications during the hospitalization. Eighteen (4.70%) patients visited unscheduled outpatient clinic within 7 days, and 6 (1.57%) patients were re-hospitalized within 30 days after discharge. The remaining patients had no significant adverse events during the 30-day follow-up. The average length of hospital stay was 2.27±0.35 d. The length of hospital stay was over 48 h in 48 (12.53%) patients. The independent risk factor for delayed discharge was lobectomy or combined resection (OR=3.015, 95%CI 1.174-7.745, P=0.022). Conclusion VATS can be safely conducted under the centralized management in Day Care Unit. The risk factor for delayed discharge is the extent of surgical resection.

@#Objective To compare the short-term clinical effects of Da Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of posterior mediastinal tumors, and to explore the advantages of RATS posterior mediastinal tumor resection. Methods The clinical data of patients who underwent posterior mediastinal tumors resection through the lateral chest approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between January 2019 to January 2023 were retrospectively analyzed. According to the different surgical methods, the patients were divided into a RATS group and a VATS group. The clinical data were compared between the two groups. Results A total of 85 patients were included in this study. There were 39 patients in the RATS group, including 25 females and 14 males, with an average age of 47.6±13.0 years, and 46 patients in the VATS group, including 14 males and 32 females, with an average age of 45.3±14.7 years. All patients completed the operation successfully. The hospitalization cost in the RATS group was significantly higher than that in the VATS group (P<0.001), and the white blood cell count and neutrophilic granulocyte percentage on the first day after operation in the RATS group were lower than those in the VATS group, and the differences were statistically significant (P<0.05). The operative time, intraoperative bleeding, postoperative hospital stay, white blood cell count and neutrophil percentage on the third postoperative day, visual analogue scale score on the first and third postoperative days, duration of analgesic pump use, postoperative 12 h oxygen saturation (no oxygen inhalation), postoperative down bed time, total thoracic drainage volume, duration of drainage tube retention, and postoperative complication rates were not statistically different between the two groups (P>0.05). There was no perioperative death, conversion to thoracotomy or serious perioperative complications in both groups. Conclusion RATS resection of posterior mediastinal tumor via lateral thoracic approach is safe and feasible, and its short-term effect is similar to that of VATS via lateral thoracic single-hole approach. It is worth further comparative study to explore its benefit and cost performance.

The association of intraoperative positive end-expiratory pressure with pulmonary complications after thoracoscopic lung surgery: A propensity score-matching study / 中国胸心血管外科临床杂志

@#Objective To evaluate the correlation between positive end-expiratory pressure (PEEP) level and postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung surgery. Methods The clinical data of patients who underwent elective thoracoscopic lung surgery at West China Hospital of Sichuan University from January 2022 to June 2023 were retrospectively analyzed. Patients were divided into 2 groups according to intraoperative PEEP levels: a PEEP 5 cm H2O group and a PEEP 10 cm H2O group. The incidence of PPCs in the two groups after matching was compared using a nearest neighbor matching method with a ratio of 1∶1, setting the clamp value as 0.02. Results A total of 538 patients were screened, and after propensity score-matching, a total of 229 pairs (458 patients) were matched, with an average age of 53.9 years and 69.4% (318/458) females. A total of 118 (25.8%) patients had PPCs during hospitalization after surgery, including 60 (26.2%) patients in the PEEP 5 cm H2O group and 58 (25.3%) patients in the PEEP 10 cm H2O group, with no statistically significant difference between the two groups [OR=0.997, 95%CI (0.495, 1.926), P=0.915]. Multivariate logistic regression analysis showed that PEEP was not an independent risk factor for PPCs [OR=0.920, 95%CI (0.587, 1.441), P=0.715]. Conclusion For patients undergoing thoracoscopic lung surgery, intraoperative PEEP (5 cm H2O or 10 cm H2O) is not associated with the risk of PPCs during hospitalization after surgery, which needs to be further verified by prospective, large-sample randomized controlled studies.
