Evolución de la técnica follicular unit extraction (FUE) / Evolution of the follicular unit extraction (FUE) technique

El microtrasplante capilar, método FUE, es la cirugía para la recuperación capilar que consta en la extracción de unidades foliculares con punches de distintos diámetros y longitudes, desde una zona llamada dadora, generalmente occipital y/o temporal aunque pueden utilizarse otras partes del cuerpo como barba, tórax, abdomen y pubis, para luego de seleccionarse y conservarse en forma adecuada ser implantadas en la llamada zona receptora. Tanto los avances en la técnica como en el uso de instrumental de última generación generan resultados mejores y más naturales, con una recuperación más rápida y menor daño de sus zonas dadoras.

Hair transplant, FUE method, is surgery for hair recovery that consists of the extraction of follicular units with punches of different diameters and lengths, from an area called the donor; usually occipital and/or temporal; although they can be used on other parts of the body such as beard, thorax, abdomen and pubes. After being appropriately selected and preserved, they are implanted in the so-called receiving area. Both advances in technique and in the use of cutting-edge instruments generate better and more natural results, with faster recovery and less damage to the donor areas

Doar ou não doar: significados da negação familiar para a doação de órgãos e tecidos / To donate or not to donate: meanings of family refusal to the refusal to donate organs and tissues

Objetivo: Compreender os significados atribuídos por familiares sobre a negação para a doação de órgãos e tecidos. Métodos: Estudo descritivo, exploratório, com abordagem qualitativa. Utilizou-se um questionário semiestruturado para a coleta de dados e a análise temática de conteúdo para o tratamento dos dados obtidos. A amostragem de 10participantes foi definida pelo critério de saturação teórica. Resultados: Percebeu-se a tendência de os familiares consentirem a doação quando bem orientados sobre a morte encefálica e de a finalidade humanística do doador, mas os principais obstáculos para a negação da doação são a falta de conhecimento sobre a doação de órgãos, o medo da mutilação do corpo por não saber como é realizado o procedimento de retirada de órgãos e tecidos, a burocracia com a demora na liberação do corpo para sepultamento e a discordância entre os familiares. Conclusão: Os significados da negação familiar permeiam o medo, o sentimento de vazio, a falta de informação sobre os processos que envolvem a doação e captação de órgãos e tecidos, bem como aspectos culturais e religiosos, embora o desespero, a dor e a falta de empatia das equipes de saúde também possam corroborar a recusa.

Objective: To understand the meanings attributed by family members about the refusal to donate organs and tissues.Methods: Adescriptive and exploratory study with a qualitative approach. A semi-structured questionnaire was used for data collection and thematic content analysis was employed for the treatment of the data obtained. The sample comprised by 10participants was defined by means of the theoretical saturation criterion. Results: There was a tendency for family members to consent to thedonation when well-oriented about brain death and the humanistic purpose of the donor, but the main obstacles to refuse donation are as follows: lack of knowledge about organ donation, fear of body mutilation for not knowing how the procedure for removingorgans and tissues is performed, bureaucracy with the delay in releasing the body for burial and disagreement between family members.Conclusion:The meanings of family refusal permeate fear, a feeling of emptiness and lack of information about the processes involved in organ and tissue donation, as well as cultural and religious aspects, although despair, pain and lack of empathy of the health teams can also corroborate refusal.Descriptors:Tissue and Organ Procurement; Transplant; Family relationships.

Nefrectomía totalmente laparoscópica para donante vivo de riñón: Características y desenlaces en una institución de alta complejidad en Colombia. Serie de casos / Total laparoscopic nephrectomy for a living kidney donor: Characteristics and outcomes in a single center from Colombia. Case series

Introducción. El trasplante es la mejor opción de tratamiento para los pacientes con enfermedad renal terminal, sin embargo, existe discrepancia entre las listas de espera y la disponibilidad de órganos a partir de la donación cadavérica. Buscando aumentar el número de órganos disponibles se implementó el trasplante con donante vivo. A partir de la introducción de técnicas mínimamente invasivas para la nefrectomía, el donante vivo ha logrado cifras cercanas al 50 % de los trasplantes realizados en muchas instituciones, debido a los beneficios propios del procedimiento. El objetivo de este estudio fue describir los resultados después de la incorporación del procedimiento totalmente laparoscópico en nuestra institución. Métodos. Se hizo un análisis retrospectivo de las características de los pacientes llevados a nefrectomía para obtención de injerto por técnica totalmente laparoscópica y los resultados en un solo centro en Cali, Colombia, desde noviembre de 2019 hasta octubre de 2022. Los datos fueron obtenidos mediante la revisión de las historias clínicas electrónicas. Resultados. Se realizaron 78 nefrectomías para obtención de injerto con técnica totalmente laparoscópica. El tiempo operatorio promedio fue de 152 minutos, el sangrado promedio fue de 12 ml, la estancia hospitalaria promedio del donante fue de 2,8 días. La tasa de complicaciones fue de 7,6 % (4 pacientes con complicación Clavien-Dindo I y 2 pacientes Clavien-Dindo IIIb). No se presentó ningún caso de mortalidad. Conclusiones. La técnica totalmente laparoscópica resulta ser una técnica segura con baja tasa de morbilidad y excelentes beneficios para los donantes.

Introduction. Kidney transplant is the best treatment option for end-stage renal disease. However, the discrepancy between waiting lists and the availability of organs from cadaveric donation is well known. Organ transplantation with a living donor was implemented to increase the number of organs available. Since the introduction of minimally invasive techniques for nephrectomy, living donors have achieved figures close to 50% of transplants performed in many institutions due to the procedure's benefits. In our country, the experiences described are from the hand-assisted technique. This is the first description after incorporating the laparoscopic procedure. Methods. A retrospective analysis of the characteristics and results of all patients undergoing nephrectomy to obtain a graft using a laparoscopic technique was carried at a single center in Cali, Colombia, from November 2019 to October 2022. The electronic medical records were reviewed to obtain the data. Results. Seventy-eight nephrectomies were performed to obtain a graft with a laparoscopic technique. The mean operating time was 152 minutes, the average bleeding was 12 cc, and the average hospital stay was 2.8 days. The complication rate was 7.6% (four patients with Clavien-Dindo I complication and two Clavien-Dindo IIIb patients). There were no cases of mortality. Conclusions. The laparoscopic technique is safe, with a low morbidity rate and excellent benefits.

Introduction: The process of organ and tissue donation is defined by actions to transform a Potential Donor (PD) into an effective donor and begins with the diagnosis of brain death. Objective: To analyze the clinical and sociodemographic profile of potential organ donors, as well as the factors that influence organ donation. Methods: This is a quantitative, cross-sectional, retrospective, and analytical research carried out in a region of Northeast Brazil by collecting data from 455 medical records of patients with brain death, who were diagnosed using a structured form. Subsequently, descriptive analyzes were carried out and for the associations between the independent and dependent variables, the Pearson's chi-square test was used. Results: The age groups with the highest incidence were between 21 to 40 years old and 41 to 60 years old, with a 33.8 % each, with a predominance of males (64.1%). Regarding the cause of death, traumatic brain injury was the most common with a 36.5% of the sample. From the 83.3% of the family members that were interviewed, 53.5% of them authorized the donation. Male potential donors constituted the 59.01% of the authorized donations (positive interviews). There was no relationship between the interview results and the age group of the PD. When correlating the results of family interviews and the cause of death, 40.63% of them were caused by traumatic brain injury and, out of this total, 63.63% had the donation authorized. Conclusion: The most effective donors were young and male whose cause of brain death was traumatic brain injury and whose families allowed the donation.

Adverse Events Reporting Systems in Cells, Organs, and Tissues Donation and Transplantation: Scoping Review.

BACKGROUND: This study aimed to map adverse events reporting systems in cells, organs, and tissues donation and transplantation, including the terms applicable in each system and scientific literature. METHODS: This was a scoping review using the Joanna Briggs Institute method. A search strategy in 3 phases was used, and searches were conducted in PubMed, Embase, LILACS, Scholar Google, and government and organ donations and transplantation associations' sites during June and August 2021. Data collection and analysis were independently made by 2 researchers. The scoping review protocol was registered. RESULTS: Twenty-four articles and other materials were selected for data collection. Eleven reporting systems were analyzed, and terms were identified. CONCLUSIONS: Adverse reporting systems in cells, organs, and tissues donation and transplantation were mapped. The main features are presented, which can help develop new and better systems, with an important discussion about the terms used.

The Use of the Implantable Doppler Probe as a Blood Flow Monitoring Device in Clinical Settings: A Narrative Review of the Evidence.

OBJECTIVES: In the past decade, the implantable Doppler probe has been studied widely as a blood flow-monitoring device in reconstructive and transplant surgical specialities. Its utility as an effective postoperative monitoring technique is still debatable, with no clear guidelines in clinical practice. Here, we mapped the current evidence on the usefulness of the implantable Doppler probe as a blood flow-monitoring device. The objective was to present an up-to-date assessment of the benefits and limitations of using implantable Doppler probes in clinical and experimental clinical settings. MATERIALS AND METHODS: We conducted a literature search using the Cochrane Library and Healthcare Databases Advanced Search and using implantable Doppler probe, transplant, graft, and flap as key words. The search yielded 184 studies, with 73 studies included after exclusions. We evaluated, synthesized, and summarized the evidence from the studies in tabular form. RESULTS: There is clinical equipoise regarding the effectiveness of implantable Doppler probe as a flow sensing technique. The main reason is the lack of information and gaps in the evidence regarding the benefits and limitations of using implantable Doppler probes in clinical practice. CONCLUSIONS: The implantable Doppler probe has the potentialto be used as an adjunctpostoperativeblood flow-monitoring device. However, keeping in view of technical limitations, its signals should be interpreted alongside traditional clinical assessment techniques to determine the patency of microvascular anastomosis. Although evidence in this review will inform clinical practice in transplant and reconstructive surgical specialties, a prospective randomized controlled study with a larger patient cohort is required to evaluate the effectiveness of this probe in clinical settings.

Transplant Nursing.

These nurses coordinate care through the transplantation process.

The current state of transplant advanced practice providers: results of the advanced practice provider practice survey.

Advanced practice providers (APPs) are trained, licensed health care providers. The American Society of Transplant APP community of practice developed an electronic survey to investigate transplant APP demographics, scope of practice, and academic activities. We defined the top of scope of practice as delivering health care to the fullest extent of APP education and training as allowed by state laws and regulations. From July 11, 2020, to August 31, 2020, 307 invitations were e-mailed and survey links were distributed electronically on the community of practice hub and social media. Two hundred fifty-three APPs responded. APPs practice in inpatient and outpatient settings. Among the respondent APPs, 11.5% assist in the operating room (OR), 46.3% of inpatient and 46.6% of outpatient APPs perform procedures, and 17.8% run specialized APP clinics. 26.2% feel they do not function at the top of their scope of practice and 29.7% were expected to function as a coordinator some or all of the time. Forty-three percent gave invited lectures, 41.5% have published, and 69.2% teach physician trainees. 74.7% and 35.1%, respectively, would like to participate in research and teach but are limited by time, opportunity, and experience. APPs should practice at the top of their scope of practice. Clinical workloads and lack of time limit the ability of APP to teach and contribute to evidence-based practice.
