This study was performed to support an expeditionary team of Colombian scientists seeking to promote and undertake research in various scientific fields in Antarctica.The work was part of the Colombian Antarctic Program,which comprises various projects intended to lead to a permanent Colombian scientific base being established in the Antarctic.The first step involved installing a Colombian-made wind turbine to produce electricity at a permanent base.The aeolian turbine was designed to provide sufficient electricity to illuminate and heat a small base.The turbine was constructed using readily accessible materials but taking the Madrid Protocol environmental regulations into consideration.The project was performed at the Argentinian Antarctic Marambio Station on Seymour Island,off the Antarctic Peninsula.An initial field study performed in 2015 was the first of three phases of the project.In the initial phase,local meteorological data were gathered to support development of a prototype turbine and to allow a design to be selected that was robust enough for the extreme environmental conditions.The wind turbine was then constructed in Colombia.The second phase involved transporting the turbine to Antarctica and installing it at the Marambio Station in 2018.Finally,the physical conditions of structural and electronic components of the turbine were carefully inspected at the beginning of 2020(after the turbine had operated continually for^2 years)to allow repairs to be made and any necessary re-engineering to be performed.

TBI pathology： Traumatic brain injury （TBI） is caused by an external force to the head, resulting in trauma to the brain. Approximately 1.7 million Americans suffer from TBI every year. Out of the 1.7 million suffering from TBI, an estimated 52,000 injuries result in death, leaving a mass amount of peo- ple with symptoms that could last a few days, a few years, or their entire life （Faul et al., 2010）. TBI can be classified as mild, moderate and severe. Depending on the classification and the extent of the injury, TBI can cause both physical symptoms and cognitive disorders （lozano et al., 2015）.

Introduction: The standard treatment for complex wound care is autografting. The advent of dermal substitutes has provided a novel tool for the preparation of the bed to be grafted. However, most types of dermal matrices require the application of a skin graft a second time. Currently, other strategies have been developed to improve the vascularization process, such as negative pressure wound therapy (NPWT), which has been reported to reduce the time required for vascular growth and dermal matrix integration and thus achieve a shorter waiting period for autologous graft application. The present study aims to evaluate the effectiveness and safety of dermal matrix management associated with NPWT in the treatment of complex wounds. Methods: Seven patients with a diagnosis of complex wounds were enrolled in this study between July 1, 2015, and June 31, 2016. After debridement and having an adequate wound bed, patients who met the criteria for the application of combined therapy were treated with dermal substitutes and a negative pressure system. The percentage of graft integration into the wound bed, complications, length of hospital stay, and duration of therapy were analyzed. Results: The mean age was 42.5 ± 16 (39 - 54) years old;three women and four men were included in the study. The approximate size of skin loss was 120.7 ± 75 cm2 (25 - 250 cm2). The combined therapy of dermal matrix plus NPWT was instituted in all cases for a period of 14 days. There were no complications, with 100% graft integration in 6 of 7 cases. Patients were discharged after a mean hospital stay of 5.4 days. Conclusions: This study demonstrates that the utilization of combined dermal matrix plus NPWT therapy can be performed safely and effectively in patients with complex wounds with low complication rates and a short hospital stay.

Managament Wound Healing: The Importance of a Wound Clinic in Hospital Centers

现代整形外科(英文) 2023年第4期13卷 118-125页

作者： Alfredo Chama Naranjo Cuahutémoc Márquez Espriella Alberto Ignacio Cahuana Quispe Barbosa Villarreal Fernando Ana Priscila Campollo López Mauricio Gutiérrez Álvarez Carlos Emiliano García Córdova Jesús Ricardo García Corral Cuervo Vergara Marco Antonio Jorge Luis Rosales Becerra Dávila Díaz Rodrigo Edgar Alan Guillen Martínez Marín Canto Miguel Eduardo Luis Arturo Herrera lozano Ochoa Contreras Erick cesar Martinez Villalobos Claudia Nallely Cruz Soto Randall Camacho Rodriguez Hayah Ricardo Alberto Pulido López Edwing Michel Jaimes Durán Department of Plastic and Restrictive Surgery Hospital Central Sur de Alta Especialidad Pemex Mexico City Mexico

Background: In clinical practice, acute and chronic wounds continue to be a challenge. Unfortunately, wound care is often inadequate or inappropriate. The implementation of wound clinics involving an interdisciplinary team for wound care and treatment yields favorable clinical outcomes as well as a reduction in economic expenses due to a higher rate of healing, a decrease in hospital stays, and a reduction in the number of readmissions. The establishment of wound clinics enhances the utilization of diagnostic, preventive, and therapeutic resources, improving the quality of life of patients and facilitating their reintegration into their normal lives. The objective is solely to describe the importance of wound clinics in the medical profession. Methods: A retrospective literature search was conducted to include articles no more than 10 years old that reported measures or results of the study in order to perform a literature review and describe the importance of wound clinics in medical practice. Results: A total of 7 articles were obtained with the inclusion criteria, the most recent being from the year 2023 and the oldest from 2013. Conclusion: An important area for improvement in the healthcare industry is the management and treatment of complex wounds. The establishment of wound clinics offers comprehensive and specialized care for both acute and chronic complex wounds with the goal of enhancing secondary illness patients’ prevention, treatment, and rehabilitation.
