Effect of Hyperbaric Oxygen Therapy and Adipocyte Stem Cell on the Viability of Degloving Injury: A Murine Model.

INTRODUCTION: Degloving soft tissue injuries (DSTIs) involve skin and tissue detachment from muscle or fascia. Surgical treatments exist, but they cannot prevent necrosis. OBJECTIVE: Our aim was to investigate the effects of hyperbaric oxygen therapy (HOT) and adipocyte stem cell (ASC) treatment on tissue viability in degloving injuries in a murine model. METHODS: 32 animals were submitted to a degloving flap surgery in the dorsal region and were allocated in four groups (n=8/group): Control: suture only; HOT: 2-hour daily therapy in 100% oxygen at 2.0 ATA for 7 days; ASC: injected with 1x106 stem cells; ASC+HOT: stem cells injection plus HOT therapy. We performed macroscopic measurements, blood flow, histology, and expression of inflammation genes. RESULTS: After 7 days, HOT, ASC, and ASC+HOT groups had significantly more viable tissue compared to Control (97%, 90%, 81% vs. 6%). Viable area ratios were higher in HOT and ASC than Control. Blood flow in the injury's distal region was higher in HOT, ASC, and ASC+HOT compared to Control. Vascular density was higher in HOT and ASC+HOT than Control. Inflammatory cells decreased by 40% in HOT, 50% in ASC+HOT, and 75% in ASC. Gene Cd68 expression was lower in HOT than Control. Il10 expression was lower in HOT but higher in ASC and ASC+HOT than Control. CONCLUSION: This study suggests that the HOT can benefit the degloving injury flap model in the early phase of wound healing, and the association of ASC with HOT could benefit the wound healing in a later phase.

Kinect-Based Gait Analysis System Design and Concurrent Validity in Persons with Anterolateral Shoulder Pain Syndrome, Results from a Pilot Study.

As part of an investigation to detect asymmetries in gait patterns in persons with shoulder injuries, the goal of the present study was to design and validate a Kinect-based motion capture system that would enable the extraction of joint kinematics curves during gait and to compare them with the data obtained through a commercial motion capture system. The study included eight male and two female participants, all diagnosed with anterolateral shoulder pain syndrome in their right upper extremity with a minimum 18 months of disorder evolution. The participants had an average age of 31.8 ± 9.8 years, a height of 173 ± 18 cm, and a weight of 81 ± 15 kg. The gait kinematics were sampled simultaneously with the new system and the Clinical 3DMA system. Shoulder, elbow, hip, and knee kinematics were compared between systems for the pathological and non-pathological sides using repeated measures ANOVA and 1D statistical parametric mapping. For most variables, no significant difference was found between systems. Evidence of a significant difference between the newly developed system and the commercial system was found for knee flexion-extension (p < 0.004, between 60 and 80% of the gait cycle), and for shoulder abduction-adduction. The good concurrent validity of the new Kinect-based motion analysis system found in this study opens promising perspectives for clinical motion tracking using an affordable and simple system.

CAN SENSORY DISTURBANCES DUE TO INJURY TO THE INFRAPATELLAR BRANCH OF THE SAPHENOUS NERVE BE PREVENTED BY AN OBLIQUE INCISION?

Objective: To evaluate the incidence of injuries to the infrapatellar branch of the saphenous nerve (IPBSN) after anterior cruciate ligament reconstruction (ACLR) with an oblique incision for hamstring graft harvesting. Methods: In total, 59 knees (from 57 patients) were evaluated in the follow-up of ACLR for six months. We drew a horizontal line parallel to the ground, passing through the most medial portion of the surgical incision and another, perpendicular to the first, starting at the tibial tuberosity (TT). We measured the length and angle of the cut, the distances from its most medial point to the perpendicular line, and from the TT to the horizontal line. Skin sensitivity was tested with a brush and the altered sensitivity area was measured. Patients were asked about difficulties in activities daily of living (ADL). Results: A total of 27 knees (45.7%) had sensory disorders, which persisted until the sixth postoperative month in 92.6% of them. The ADL were compromised in one knee (3.7%). No significant differences were found between the groups with and without changes in sensitivity regarding age, affected side, incision angle, or measured distances. The incision size was larger in the group without alteration in sensitivity. Conclusions: An oblique incision did not avoid IPBSN injuries. This condition rarely compromised the ADL. Level of Evidence II, Lesser Quality Prospective Study.

Objetivo: Avaliar a incidência de lesões do ramo infrapatelar do nervo safeno (RIPNS) na reconstrução do ligamento cruzado anterior (RLCA), com incisão oblíqua para a coleta do enxerto dos isquiotibiais. Métodos: 59 joelhos (57 pacientes) foram avaliados no pós-operatório da RCLA, por seis meses. Traçamos uma linha horizontal paralela ao solo, passando pela porção mais medial da incisão cirúrgica, e outra perpendicular à esta, iniciando na tuberosidade tibial (TT). Medimos o comprimento e a angulação do corte, as distâncias do ponto mais medial do corte à linha perpendicular e outra, da TT, à linha horizontal. A sensibilidade da pele foi testada com um pincel, e a área alterada foi mensurada. Os pacientes foram questionados sobre as dificuldades nas atividades diárias da vida (ADV). Resultados: 27 joelhos (45,7%) apresentaram distúrbios sensitivos, persistentes até o sexto mês pós-operatório em 92,6% deles. As ADV foram comprometidas em um joelho (3,7%). Não houve diferença significante entre os grupos com e sem alterações da sensibilidade, relativamente à idade, ao lado comprometido, ao ângulo da incisão ou às distâncias medidas. O tamanho da incisão foi maior no grupo sem alteração de sensibilidade. Conclusões: Uma incisão oblíqua não evitou lesões no RIPNS. Essa condição raramente comprometeu as ADV. Nível de Evidência II, Estudo Prospectivo de Menor Qualidade.

Minimally Invasive Quadricepsplasty Using the Adolphson-Cerqueira Technique: A Retrospective Study after 1-Year of Follow-up.

Aim: Knee stiffness limits activities of daily living with treatment having no gold standard technique currently. We present follow-up data 1-year after quadricepsplasty using the Adolphson-Cerqueira technique for the treatment of knee stiffness in a Brazilian population sample. Materials and methods: This retrospective study included patients who underwent a quadricepsplasty using the Adolphson-Cerqueira technique between January 2006 and March 2023 at our institution. The inclusion criteria were: (1) Knee stiffness with a range of motion <70°; (2) Patellar excursion ≥2 mm on physical examination; (3) Available knee radiography in the anteroposterior and lateral views; and (4) A follow-up at 1 year postoperatively. The Judet Classification was used to assess the outcome of the quadricepsplasty. Results: Sixty-seven patients were included. The results were 6% poor, 31.3% fair, 44.8% good, and 17.9% excellent according to the Judet Classification. A correlation was observed between age and the gain in range of motion at the 1-year postoperative follow-up, and between the gain in range of motion intraoperatively and that at the 1-year follow-up. There were five cases of complications (7.46%): one of patellar fracture, three of quadriceps tendon rupture, and one of avulsion fracture in the superior pole of the patella. Conclusion: Quadricepsplasty using the Adolphson-Cerqueira technique produced satisfactory results overall for improving knee joint stiffness and had a complication rate comparable with other currently used techniques. Clinical significance: Loss of knee range of motion remains a difficult problem without there being a clear gold standard in treatment. Many different options are described in the literature. We provide a further option with follow-up results. How to cite this article: Cerqueira FS, Silva L, Kropf LL, et al.

Risk factors and outcomes of ventilator-associated pneumonia in patients with traumatic brain injury: A systematic review and meta-analysis.

BACKGROUND: Ventilator-associated pneumonia (VAP) is a common complication in traumatic brain injury (TBI) patients, which increases morbidity and negatively affects outcomes. Risk factors and outcomes in these patients remain controversial. The aim of the present study is to explore the risk factors and clinical outcomes of patients with VAP and TBI. METHODS: Two researchers conducted independent systematic literature searches of Pubmed, Cochrane Database, Scopus, Medline Ovid, Science Direct databases, published from inception to January 2024. The Newcastle-Ottawa scale was used to assess study quality. A meta-analysis was performed using a random-effects model when heterogeneity I2 > 50 % and a fixed-effects model when I2 < 50 %; in addition, a subgroup analysis was performed to explore VAP risk factors, and publication bias was assessed with the funnel plot and Begg's and Egger's tests. All results were considered statistically significant when p < 0.05. The certainty of the evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology. RESULTS: Twelve studies were included in the meta-analysis with a total of 2883 patients. Male gender [OR 1.58 (95 % CI 1.23, 2.02) p < 0.05 I2 0 %] and abbreviated injury scale (head: H-AIS) [≥ 3 OR 2.79 (95 % CI 1.58, 4.93) p < 0.05 I2 0 %] increased the risk of VAP. After subgroup analysis, blood transfusion on admission [OR 1.97 (95 % CI 1.16-3.35) p ≤0.05 I2 5 %] and barbiturate infusion [OR 3.55 (95 % CI 2.01-6.30) p ≤0.05 I2 0 %] became risk factors. Prophylactic antibiotic use [OR 0.67 (95 % CI 0.51-0.88) p ≤0.05 I2 0 %] and younger age MD -3.29 (95 % CI -5.18, -1.40) p ≤0.05 I2 41 %] emerged as significant protective factors. In VAP patients ICU stay [MD 7.02 (95 % CI 6.05-7.99) p ≤0.05 I2 37 %], duration of mechanical ventilation [MD 5.79 (95 % CI 4.40, 7.18) p ≤0.05 I2 79 %] and hospital stay [MD 11.88 (95 % CI 8.71-15.05) p ≤0.05 I2 0 %] were significantly increased. The certainty of the evidence was moderate-high for the outcomes studied. CONCLUSIONS: Male gender, H-AIS ≥ 3, blood transfusion on admission, and barbiturate infusion were risk factors for VAP. In patients with VAP, ICU stay, duration of mechanical ventilation, hospital stay were significantly increased.

Effects of photobiomodulation therapy associated with motor control exercise for chronic non-specific low back pain: protocol for a randomised placebo-controlled trial.

Photobiomodulation therapy (PBMT), as an adjunct therapy to exercise, can reduce pain in musculoskeletal disorders. In addition, PBMT associated with exercise decreases fatigue, accelerates muscle recovery and enhances performance and gain through different training protocols. Although it has not been investigated, the association of PBMT and exercise therapy could be an alternative to improve the positive effects of exercise in patients with non-specific low back pain (LBP). Therefore, we aim to evaluate the effects of PBMT associated with motor control exercise (MCE) versus placebo associated with MCE in patients with chronic non-specific LBP. This is a prospectively registered, two-arm, randomised, placebo-controlled, triple-blind trial. A total of 148 patients with chronic non-specific LBP will be randomised to either active PBMT associated with MCE or placebo PBMT associated with MCE. Treatment sessions will be provided twice a week for 6 weeks. The primary outcomes will be pain intensity and general disability measured at the end of the treatment. The secondary outcomes will be pain intensity and general disability measured 1 month after the end of the treatment, 3, 6 and 12 months after randomisation, in addition to levels of prostaglandin E2 measured at the end of the treatment. Medication intake, cointerventions and adverse events will be measured at all time points. This study was approved by the Research Ethics Committee of Irmandade de Santa Casa de Misericórdia de Porto Alegre. The results will be disseminated through scientific publications and presentations at scientific meetings. Trial registration number: NCT05487118.

Sociopolitical, clinical, and ethical challenges of sustainable fracture care in Haiti.

INTRODUCTION: In low- and middle-income countries such as Haiti, musculoskeletal injuries are the leading cause of morbidity and mortality. Untreated injuries can contribute to decreased mobility, leading to disability and reduced productivity for individuals. The accessibility of timely fracture care poses a substantial challenge in Haiti, where socioeconomic instability and recent surges in gang violence exacerbate an already strained healthcare infrastructure. This manuscript delves into the intricate barriers to sustainable fracture care in Haiti, shedding light on the sociopolitical landscape and clinical challenges that influence the delivery of orthopedic services. ETHICAL DISCUSSION: The ethical considerations in providing fracture care in Haiti are multifaceted, including classic medical principles, self-preservation in the face of violence, issues of justice in resource and service allocation, and concerns of nonmaleficence in the context of international volunteers. These ethical dilemmas arise from the complex interplay of limited resources, the dangers posed by the current sociopolitical climate, and the involvement of international aid in a vulnerable healthcare system. CONCLUSION: To address the clinical and ethical conflicts of providing fracture care in Haiti, solutions include education and training of Haitian orthopedic surgeons, capacity building of healthcare facilities, and establishing ethical standards for international volunteers. This comprehensive approach is vital for advancing sustainable fracture care in Haiti and other resource-limited settings.

Use of Prophylactic Antibiotics in Hand Surgeries in Colombia.

PURPOSE: The aim of the investigation was to determine the rate of prophylactic antibiotic use in hand surgeries and the factors related to their use in a group of Colombian patients. METHODS: This was a descriptive study of patients undergoing hand surgery between January 2021 and December 2022. Sociodemographic, clinical, and pharmacological variables were analyzed. The use of prophylactic antibiotics in clean wounds was considered inappropriate except in those who needed placement of an internal fixation implant. Variables related to inappropriate use of prophylactic antibiotics were analyzed. RESULTS: A total of 523 patients were reviewed, with an average age of 44.3 years; 51.2% were men. Most of the patients had a diagnosis of hand fracture (28.7%), trigger finger (24.5%), or ganglion (18.5%). The surgical wound was considered clean in 79.0% of cases. A total of 91.0% received prophylactic antibiotics, mostly cefazolin (63.3%). Some 55.7% were considered inappropriate by our criteria. Women (odds ratio [OR], 3.19; 95% confidence interval [CI], 1.85-5.47), middle-low to high socioeconomic status (OR, 1.88; 95% CI, 1.05-3.38), treatment in clinic #1 (OR, 9.67; 95% CI, 4.81-19.43), history of diabetes mellitus (OR, 2.90; 95% CI, 1.07-7.86), and diagnosis of trigger finger (OR, 19.92; 95% CI, 9.95-39.88), ganglion (OR, 24.53; 95% CI, 11.72-51.34), or tenosynovitis (OR, 19.61; 95% CI, 6.78-56.73) were associated with receiving inappropriate prophylactic antibiotics. At hospital discharge, 60.6% received prophylactic antibiotics. CONCLUSIONS: In a low-middle income country, the use of inappropriate antibiotics in hand surgical procedures is as common as in higher-income countries. The causes appear multifactorial, including the characteristics of the health systems, doctors, and patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Analysis of thumb pulp reconstruction based on different local flaps: A systematic review.

Background: The reconstruction of the thumb's pulp is challenging when considering that there is no consensus on which local flap will provide better prognosis and less financial impact. The aim of this study was to analyze the outcomes of the most used flaps for the trauma to the volar substance of the thumb, validating the main indications. Methods: This systematic review adhered to PRISMA guidelines and electronic searches were conducted in multiple databases (MEDLINE/PubMed, Virtual Health Library, Embase and Scopus) with studies published in the last ten years - until April 2022. Results: The search resulted in the screening of 573 records, and twenty studies were included. Among the flaps analyzed and compared by outcomes and prognostic factors, there are First Dorsal Metacarpal Artery (FDMCA), modified (MFDMCA), Moberg flap, Heterodigital Neurovascular Island, Neurovascular Island Pedicle and Modified Littler. Conclusion: Through this literature review, we can analyze different flaps widely used in the daily life of hand surgeons. The flaps that were also positive in a global context, but with few criticisms, are the MFDMCA, Moberg Flap, Neurovascular Island pedicle flap and FDMCA. However, it is important for the surgeon to consider different prognostic factors when choosing the flap, since these aspects directly impact the return to daily activities after the procedure.

HealthyTrailsBR - The prevalence of running-related injuries and cramps, and the description of personal and running characteristics in Brazilian trail runners: a cross-sectional study.

BACKGROUND: Physical activity in natural environments, such as trail running, is a way to nurture physical and mental health. However, running has an inherent risk of musculoskeletal injuries. OBJECTIVES: To investigate the prevalence of running-related injuries (RRI) and cramps, and to describe the personal and training characteristics of Brazilian trail runners. METHODS: A total of 1068 trail runners were included in this observational cross-sectional study. The participants had at least six months of trail running experience. The data were collected between April 2019 and February 2020 through an online and self-reported survey. RESULTS: The point prevalence of RRIs was 39.2 % (95 % credible interval [CrI]: 36.3, 42.1). The body region with the highest point prevalence was the knee. The 12-month period prevalence of RRIs was 69.2 % (95 %CrI: 66.4, 72.0). The body region with the highest 12-month period prevalence was the lower leg. 1- and 12-month period prevalence of cramps was 19.5 % (95 %CrI: 17.1, 21.9) and 36.0 % (95 %CrI: 33.0, 38.8), respectively. Triceps surae was the muscle most affected by cramps. CONCLUSIONS: Two in 5 (40 %) trail runners reported being injured at the time of data collection, and about 2 of 3 reported previous RRIs in the last 12 months. The most prevalent injured body regions were the knee and the lower leg. One in 5 trail runners reported cramps in the last month, increasing to 36 % in the last 12 months. Knowing better the characteristics of the population and the burden of health conditions may inform better decisions regarding implementation actions toward trail running practice.

WOUND-Q questionnaire: Translational and cross-cultural adaptation for Brazilian Portuguese.

Studies shows that 1%-2% of world population will develop chronic skin wound in their lifetime. Nowadays, the patient report outcome measure (PROM) questionnaires are used to evaluate the patient's quality of life. However, several PROM's questionnaires analyse specific chronic wounds. In this sense, WOUND-Q toll was designed to evaluate all types of wounds. Because of the WOUND-Q wide applicability, the use of WOUND-Q is helpful for other countries. This study aimed to translate and adapt WOUND-Q tool for Brazilian Portuguese language. Two independent translators translated the WOUND-Q questionnaire from English to Brazilian Portuguese. Then these translators build Version 1 (T1) and version 2 (T2). In a consensus meeting, a third senior author defined the final version. In the back translation process, an English proficient translator translated the Brazilian Portuguese version to the original version. After another consensus, a final version was defined. Then, our group performed a cognitive test to validate this version. After the first translation, the comparison of version T1 and T2 achieved an intraclass correlation coefficient of 77%. The back translation showed the need of few adjustments. For the cognitive test, the mean age was 44.1 ± 9.3 years. Only one question was changed to improve comprehensiveness. In the review phase, few adjustments were performed to the final Brazilian Portuguese version, mostly regarding verbal tense and prepositions. In conclusion, this study successfully translated and adapted the WOUND-Q questionnaire for a Brazilian Portuguese version.

Surgical treatment of traumatic rupture of the teres major tendon in a professional gymnast: a case report.

Teres major injuries are rare and are generally treated conservatively, except in high-performance athletes. This report describes a case of traumatic rupture of the teres major at its myotendinous junction in a professional gymnast. The patient underwent surgical treatment 10 days after the injury. Six months post-surgery, the patient achieved complete recovery of the range of motion and strength, returning to the pre-injury performance level, guided by physiotherapy rehabilitation. This is the first documented case in the literature of surgical treatment of this injury in a professional gymnast. The main lesson from this case is that early surgical repair in elite athletes can result in excellent functional outcomes and allow return to sport at the pre-injury performance level.

The Influence of High Physical Demand on the Occurrence of Major Muscle and Ligament Injuries in Professional Soccer Athletes: A Systematic Review.

Objective The present systematic review aimed to investigate the influence of high physical demand on the increase in muscle and ligament injuries in professional soccer athletes. Methods We analyzed scientific publications to determine the incidences of the main injuries, their causes and mechanisms, and their association with high physical demand. We compared amateur and professional players and assessed the effectiveness of FIFA11+ as a prevention alternative. Searches occurred on Scielo, Pubmed, and Google Scholar databases. The filters were the topic, publication date (last 5 years), and study relevance. The indexing terms were the following: Overuse , Calendar , Injuries , Muscular , Ligament , Athletes , Soccer , Football . We described the main data obtained to compare and analyze the results. This study complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. Results The query resulted in 24 articles published from 2019 to 2023. The high physical demand increased the risk of injuries. Most injuries occurred in the lower limbs. The most common injuries were strains, sprains, contractures, and ligament ruptures. FIFA11+ presented itself as a viable prevention alternative. Conclusion We concluded that high physical demand increases the most frequent muscle and ligament injuries in professional soccer players, that is, strains, sprains, contractures, and ligament rupture, suggesting the FIFA11+ program as a prevention alternative.

Wrist Immobilization after Surgical Decompression of the Median Nerve in Carpal Tunnel Syndrome: A Systematic Review.

Objective The most common compressive neuropathy of the upper limbs is carpal tunnel syndrome (CTS). Historically, there has been a tendency to apply immobilization in the postoperative period, a practice that has decreased in recent years. This review aims to assess whether there is scientific evidence to justify the use of immobilization in the postoperative care of CTS decompression. Methods The following databases were used: Biblioteca Virtual em Saúde (BVS), PubMed National Library of Medicine - (NLM), Cochrane Library, Scientific Electronic Library Online (SciELO), and EMBASE. The following inclusion criteria were used: 1) discussion of the postoperative period of median nerve decompression surgery in CTS; 2) comparison of results after surgical decompression in CTS between wrist immobilization or local dressing; 3) all languages, regardless of the year of publication; and 4) all types of publications. The following exclusion criteria were used: 1) studies that did not evaluate the postoperative period of CTS decompression; 2) lack of evaluation of the outcome related to the application of local dressing or some form of wrist immobilization after the surgical decompression procedure; and 3) repeated publications. Results The literature search resulted in 336 relevant publications. In the end, 18 publications were chosen. Systematic reviews, randomized clinical trials, and cross-sectional studies were found. Conclusions Due to the scarcity of evidence supporting the use of immobilization coupled with the higher costs associated with the practice, it has become less and less frequent in recent decades. Clinical relevance In the literature, two approaches to postoperative care for CTS decompression are described: immobilization or just local dressing. According to the available scientific evidence, it is worth evaluating which one is better.

Tratamiento no operatorio en traumatismo abdominal cerrado. Experiencia en un hospital Interzonal de la provincia de Buenos Aires / Nonoperative management of blunt abdominal trauma. Experience in a regional hospital of the province of Buenos Aires

RESUMEN Antecedentes: En las últimas décadas ha habido un cambio considerable hacia un enfoque más conservador en el tratamiento del traumatismocerrado de abdomen, con énfasis en la preservación de la función de órganos; actualmente, el tratamiento no operatorio (TNO) se ha convertido en la técnica de manejo estándar en pacientes hemodinámicamente estables con lesiones de órgano sólido. Objetivo: Describir las variables clínicas asociadas a la tasa de éxito en una serie de pacientes con TNO de trauma abdominal cerrado con lesión de órganos sólidos. Material y métodos: Estudio retrospectivo, observacional, longitudinal, analítico entre enero de 2017 y diciembre de 2022, sobre pacientes admitidos con diagnóstico de traumatismo abdominal cerrado. Las variables evaluadas fueron: edad, sexo, estadía hospitalaria, complicaciones, requerimiento de transfusiones, tasa de éxito y mortalidad. Resultados: De 2590 pacientes ingresados por Guardia de Cirugía General, 24 pacientes se internaron con diagnóstico de traumatismo cerrado de abdomen. Fueron excluidos 15 pacientes por no cumplir con los criterios de inclusión. Los 9 pacientes seleccionados tuvieron un promedio de edad de 39 años (15-80) y 9 fueron varones. En el 36% presentaron lesiones esplénicas grados I-II, 27% presentó lesión renal grado II y el 18% restante con lesión hepática grado II. La tasa de éxito del tratamiento fue del 100% en nuestra serie sin evidenciar fallos en la terapéutica instaurada. Conclusión: Con los criterios empleados en TNO del traumatismo abdominal cerrado con lesión de órganos sólidos fue factible y permitió alcanzar una alta tasa de éxito, sin mortalidad.

ABSTRACT Background: In recent decades, there has been a significant shift toward a more conservative approach to the management of blunt abdominal trauma with an emphasis on preserving organ function; currently, non-operative management (NOM) has become the standard of care for hemodynamically stable patients with solid organ injury. Objective: The aim of this study was to determine the different clinical variables associated with the success rate of NOM of blunt abdominal trauma with involving solid organs. Material and methods: We conducted a retrospective, observational, longitudinal, and analytical study of patients admitted for blunt abdominal trauma between January 1, 2017, and December 1, 2022. The variables evaluated were age, sex, length of hospital stay, complications, transfusion requirements, success rate and mortality. Results: Between January 2017 and December 2022, of 2590 patients seen in the emergency department, 24 were admitted with a diagnosis of blunt abdominal trauma. Fifteen patients did not meet the inclusion criteria. The mean age of the 9 patients included was 39 years (15-80 years) and 6 were men. Thirty-six percent had grade I and II splenic lesions, 27% had grade II renal lesions, and 18% had grade II hepatic lesions. The success rate of our series was 100% and there were no failures. Conclusion: The variables analyzed allowed us to affirm that NOM of blunt abdominal trauma with solid organ injury was feasible and allowed us to achieve a high success rate, without deaths.

Epidemiología del trauma de alta energía en Chile: análisis ecológico con registros públicos / Epidemiology of high-energy trauma in Chile: An ecological analysis using public registries

El trauma de alta energía se define como lesiones orgánicas graves resultantes de eventos que generan una gran cantidad de energía cinética, eléctrica o térmica. Constituye una importante preocupación de salud pública, representando el 10% de la mortalidad mundial. El objetivo de este artículo es describir la epidemiología del trauma de alta energía en Chile. Específicamente, se busca comparar la tasa de mortalidad por 100 000 habitantes entre los países miembros de la Organización Mundial de la Salud (OMS), realizar un análisis descriptivo de las notificaciones por Garantías Explícitas en Salud (GES) del problema de salud "politraumatizado", y analizar la tendencia de la tasa de fallecidos por causa externa en Chile. El presente estudio tiene un diseño ecológico, utilizando tres bases de datos de acceso abierto. Primero, se utilizó la base de datos de la OMS sobre fallecidos por accidentes automovilísticos en 2019. Luego, se consultó la base de datos del programa Garantías Explícitas en Salud para el problema "politraumatizado" entre los años 2018 y 2022. Finalmente, se utilizó la base de datos del Departamento de Estadísticas de Salud de Chile sobre causas de muerte entre 1997 y 2020. En 2019, Chile ocupó una posición intermedia en cuanto a la tasa de mortalidad por 100 000 habitantes debido a accidentes de tráfico. Las notificaciones el programa Garantías Explícitas en Salud por politraumatismo fueron predominantemente en hombres de entre 20 y 40 años, afiliados al sistema de salud pública. Por este motivo, el foco principal de prevención debe centrarse en este grupo. La mortalidad por accidentes mostró una tendencia decreciente, identificándose cambios estructurales significativos en los años 2000 y 2007.

High-energy trauma is defined as severe organic injuries resulting from events that generate a large amount of kinetic, electrical, or thermal energy. It represents a significant public health concern, accounting for 10% of global mortality. This article aims to describe the epidemiology of high-energy trauma in Chile. Specifically, it seeks to compare the mortality rate per 100 000 inhabitants among member countries of the World Health Organization (WHO), provide a descriptive analysis of notifications under the Explicit Health Guarantees (GES) for the health issue of polytraumatized patients, and analyze the trend in the mortality rate due to external causes in Chile. This study employs an ecological design using three open-access databases. First, the WHO database on deaths from traffic accidents in 2019 was used. Then, the GES database was consulted for the "Polytraumatized" issue between 2018 and 2022. Finally, the Chilean Department of Health Statistics database on causes of death between 1997 and 2020 was utilized. In 2019, Chile ranked in the middle regarding the mortality rate per 100 000 inhabitants due to traffic accidents. GES notifications for polytrauma predominantly involved men aged 20 to 40 years and those affiliated with the public health system, highlighting a primary focus for prevention efforts. Mortality from accidents showed a decreasing trend, with significant structural changes identified in 2000 and 2007.

Budget impact analysis of implementing trauma registries in Argentina.

INTRODUCTION: In high-income countries, quality improvement interventions and research are usually guided by trauma registries. In low- and middle-income countries, the implementation of trauma registries has been limited mainly for cost reasons. OBJECTIVE: To analyze the budgetary impact of the implementation of trauma registries in Argentina. METHODS: We estimated direct costs of implementing trauma registries in public hospitals located in cities with a population over 50,000 inhabitants. In large urban areas, we selected hospitals by estimating a minimum volume of 240 severe trauma admissions/year and using the NBATS-2 instrument with geolocation techniques. We estimated costs based on a micro-costing approach of a trauma registry developed by Fundación Trauma. Scenario analysis was carried out restricting the population to hospitals from bigger cities and/or with higher concentration of trauma patients' care. For the high budget impact threshold, we used the total health spending estimation, and alternatively the health spending of the public sector. RESULTS: For the base case, 139 hospitals from 104 cities were included, comprising 175,605 injury-related discharges and 13,707 severely injured patients/year. The average cost for the initial three years was USD 3,753,085 (21.4 USD/per patient), falling below the high budget impact thresholds. The scenarios analysis showed a significantly costs reduction. CONCLUSIONS: The implementation of trauma registries in Argentina would be affordable, and in consequence, it would improve the coordination, management and quality of care for this great public health issue.

A stacked autoencoder-based aid system for severity degree classification of knee ligament rupture.

BACKGROUND: Knee ligament rupture is one of the most common injuries, but the diagnosis of its severity tends to require the use of complex methods and analyses that are not always available to patients. AIM: The objective of this research is the investigation and development of a diagnostic aid system to analyze and determine patterns that characterize the presence of the injury and its degree of severity. METHODS: Implement a novel proposal of a framework based on stacked auto-encoder (SAE) for ground reaction force (GRF) signals analysis, coming from the GaitRec database. Analysis of the raw data is used to determine the main features that allow us to diagnose the presence of a knee ligament rupture and classify its severity as high, mid or mild. RESULTS: The process is divided into two stages to determine the presence of the lesion and, if necessary, evaluate variations in features to classify the degree of severity as high, mid, and mild. The framework presents an accuracy of 87 % and a F1-Score of 90 % for detecting ligament rupture and an accuracy of 86.5 % and a F1-Score of 87 % for classifying severity. CONCLUSION: This new methodology aims to demonstrate the potential of SAE in physiotherapy applications as an evaluation and diagnostic tool, identifying irregularities associated with ligament rupture and its degree of severity, thus providing updated information to the specialist during the rehabilitation process.

Oral focal mucinosis: A systematic review.

Oral focal mucinosis (OFM) is a rare lesion first described in 1974, but the aetiology remains unknown. Clinically, OFM presents as an asymptomatic nodular lesion and the similarity of clinical features to other soft tissue injuries makes the diagnosis difficult. The aim of this study was to integrate the demographic, clinical, and histopathological characteristics from previously published cases of OFM into a systematic review. Electronic searches without publication date restriction were performed in the following databases: Embase, PubMed, Medline, Web of Science, and Scopus. Case reports or case series of OFM published in English and presenting enough clinical and histopathological information were included. This systematic review identified 42 studies from 12 countries, comprising 113 cases of OFM. This lesion affected more females than males, usually in the fourth decade of life. The gingiva was the most common anatomical location, followed by the palate. Clinical presentation was most often an asymptomatic nodule. Imaging exams revealed that most cases did not have bone involvement. Surgical removal was the treatment of choice for most cases and only one recurrent case was reported. In conclusion, OFM is an uncommon pathology, and its diagnosis depends on histopathological analysis. The lesion could be included as a differential diagnosis of benign soft tissue lesions of the oral cavity, especially those affecting the gingiva.

Brazilian Angiology and Vascular Surgery Society Guidelines for the treatment of extracranial cerebrovascular disease.

Extracranial cerebrovascular disease has been the subject of intense research throughout the world, and is of paramount importance for vascular surgeons. This guideline, written by the Brazilian Society of Angiology and Vascular Surgery (SBACV), supersedes the 2015 guideline. Non-atherosclerotic carotid artery diseases were not included in this document. The purpose of this guideline is to bring together the most robust evidence in this area in order to help specialists in the treatment decision-making process. The AGREE II methodology and the European Society of Cardiology system were used for recommendations and levels of evidence. The recommendations were graded from I to III, and levels of evidence were classified as A, B, or C. This guideline is divided into 11 chapters dealing with the various aspects of extracranial cerebrovascular disease: diagnosis, treatments and complications, based on up-to-date knowledge and the recommendations proposed by SBACV.
