Surviving Sepsis After Burn Campaign.

INTRODUCTION: The Surviving Sepsis Campaign was developed to improve outcomes for all patients with sepsis. Despite sepsis being the primary cause of death after thermal injury, burns have always been excluded from the Surviving Sepsis efforts. To improve sepsis outcomes in burn patients, an international group of burn experts developed the Surviving Sepsis After Burn Campaign (SSABC) as a testable guideline to improve burn sepsis outcomes. METHODS: The International Society for Burn Injuries (ISBI) reached out to regional or national burn organizations to recommend members to participate in the program. Two members of the ISBI developed specific "patient/population, intervention, comparison and outcome" (PICO) questions that paralleled the 2021 Surviving Sepsis Campaign [1]. SSABC participants were asked to search the current literature and rate its quality for each topic. At the Congress of the ISBI, in Guadalajara, Mexico, August 28, 2022, a majority of the participants met to create "statements" based on the literature. The "summary statements" were then sent to all members for comment with the hope of developing an 80% consensus. After four reviews, a consensus statement for each topic was created or "no consensus" was reported. RESULTS: The committee developed sixty statements within fourteen topics that provide guidance for the early treatment of sepsis in burn patients. These statements should be used to improve the care of sepsis in burn patients. The statements should not be considered as "static" comments but should rather be used as guidelines for future testing of the best treatments for sepsis in burn patients. They should be updated on a regular basis. CONCLUSION: Members of the burn community from the around the world have developed the Surviving Sepsis After Burn Campaign guidelines with the goal of improving the outcome of sepsis in burn patients.

Anabolic and anticatabolic agents used in burn care: What is known and what is yet to be learned.

Major thermal injury induces profound metabolic derangements secondary to an inflammatory "stress-induced" hormonal environment. Several pharmacological interventions have been tested in an effort to halt the hypermetabolic response to severe burns. Insulin, insulin growth factor 1, insulin growth factor binding protein 3, metformin, human growth hormone, thyroid hormones, testosterone, oxandrolone, and propranolol, among others, have been proposed to have anabolic or anticatabolic effects. The aim of this broad analysis of pharmacological interventions was to raise awareness of treatment options and to help establishing directions for future clinical research efforts. A PubMed search was conducted on the anabolic and anticatabolic agents used in burn care. One hundred and thirty-five human studies published between 1999 and 2017 were included in this review. The pharmacological properties, rationale for the treatments, efficacy considerations and side effect profiles are summarized in the article. Many of the drugs tested for investigational purposes in the severely thermally injured are not yet gold-standard therapies in spite of their potential benefit. Propranolol and oxandrolone have shown great promise but further evidence is still needed to clarify their potential use for anabolic and anticatabolic purposes.

Tensioned reverse abdominoplasty.

BACKGROUND: Deformities of the upper portion of the abdominal wall can be difficult to solve, as in many cases abdominoplasties or mini-abdominoplasties lead to unsatisfactory results. Direct approaches to this region through inframammary incisions can be a good therapeutic option, once adequate patient selection has been performed and certain surgical principles are followed. METHODS: This technique should be primarily indicated for patients complaining of skin laxity predominantly in the upper abdomen and for patients who will have such excess after liposuction. In patients who require resection of a large amount of tissue, a single, broad, U-shaped dissection should be used, associated with midline fascia plication, when required (group 1). In patients with a smaller amount of tissue to be resected, two oblique tunnels can be made toward the navel, with no incision unification at the midline, to provide less evident scars (group 2). RESULTS: Eighteen procedures were performed: 12 in group 1 and six in group 2. Patients and surgeons were satisfied with the results. Only minor complications occurred, and they did not result in definitive sequelae. CONCLUSIONS: The principle of progressive tension suture, previously utilized in conventional abdominoplasties, is now originally employed in reverse abdominoplasties as a continuous suture, enabling proper flap positioning, keeping the inframammary sulcus at its original position, and preventing tension on the resulting scar. Tensioned reverse abdominoplasty is an easily applicable technique that provides good results and should be considered in cases of abdominal laxity predominantly in the upper abdomen.

Estudo do encurtamento global do átrio esquerdo em fetos de mães diabéticas / Study of global left atrial shortening in fetuses of diabetic mothers

OBJETIVO: Testar a hipótese de que a fração de encurtamento atrial esquerda seja menor nos fetos de mães diabéticas do que em fetos de mães sem doenças sistêmicas. MÉTODOS: Foram examinados, por ecocardiografia, 42 fetos de mães com diabetes prévio ou gestacional e 39 fetos normais de mães sem doença sistêmica (controles), com idades gestacionais a partir da 25ª semana até o termo. A fração de encurtamento atrial esquerda foi obtida pelo quociente diâmetro máximo do átrio esquerdo (AE) - diâmetro mínimo AE/diâmetro máximo AE. Os dados foram comparados pelo teste t de Student, com um alfa crítico de 0,05. RESULTADOS: Os filhos de mães diabéticas apresentaram fração de encurtamento atrial esquerda média de 0,39 ± 0,15 e os fetos do grupo controle de 0,51 ± 0,11. Esta diferença foi significativa, com p < 0,001. CONCLUSÃO: A dinâmica atrial esquerda, com diminuição do seu encurtamento global, está acentuada nos filhos de mães diabéticas. Especulamos que este parâmetro possa ser útil na avaliação da função diastólica ventricular esquerda fetal.

Study of global left atrial shortening in fetuses of diabetic mothers.

OBJECTIVE: To test the hypothesis that left atrial shortening fraction is lower in fetuses of diabetic mothers than in fetuses of mothers with no systemic disease. METHODS: Forty-two fetuses of mothers with previous diabetes or gestational diabetes and 39 healthy fetuses of mothers with no systemic disease (controls) underwent echocardiographic examination. Their gestational ages ranged from 25 weeks to term. The left atrial shortening fraction was obtained with the following formula: (left atrial maximum diameter - left atrial minimum diameter)/left atrial maximum diameter. Data were compared using the Student t test, with an alpha level of 0.05. RESULTS: Mean left atrial shortening fractions in fetuses of diabetic mothers and in those in the control group were 0.39 +/- 0.15 and 0.51 +/- 0.11, respectively. This difference was significant with P < 0.001. CONCLUSION: Left atrial dynamics, with a reduction in global left atrial shortening, is increased in fetuses of diabetic mothers. We speculate that this parameter may be useful in assessing fetal left ventricular diastolic function.

Pulsatilidade venosa pulmonar em fetos de mäes diabéticas: estudo Doppler-ecocardiográfico pré-natal / Pulmonary vein pulsatility in fetuses of diabetic mothers: prenatal Doppler echocardiographic study

OBJECTIVE: To verify the hypothesis that the pulmonary vein pulsatility index is higher in fetuses of diabetic mothers than it is in normal fetuses of nondiabetic mothers. METHODS: Twenty-four fetuses of mothers with either gestational or previous diabetes (cases), and 25 normal fetuses of mothers without systemic disease (control) were examined. Fetuses were examined through prenatal Doppler and color flow mapping. The pulmonary vein pulsatility index was obtained by placing the pulsed Doppler sample volume over the right superior pulmonary vein and applying the formula (systolic velocity - presystolic velocity)/mean velocity. RESULTS: The mean gestational age of the study fetuses was 30.3±2.7 weeks, and gestational age of the controls was 29±3.3 weeks, with no significant difference in gestational age between groups (p=0.14). Fetuses of diabetic mothers had a mean pulmonary vein pulsatility index of 1.6±1, and those of the control group had an index of 0.86±0.27. CONCLUSION: Fetuses of diabetic mothers had pulmonary vein pulsatility indexes (parameter easily obtained through Doppler echocardiography that may be related to fetal diastolic function) higher than those in fetuses of mothers with normal glycemia
