RESUMO

We present with full and proper consent of the patient, the case of a 64-year-old man with severe peripheral arterial disease and a known chronic infrarenal aortic occlusion causing severe short-distance claudication. Preoperative computed tomography angiography was significant for a new "cylindrical" calcified lesion. During the elective surgery, the lesion was confirmed to be a coronary stent. The coronary stent was confirmed to be from the patient's prior percutaneous coronary intervention to the left anterior descending artery 1 year prior. The stent was removed without complications by the surgical team. To the best of our knowledge, this is the first such case to be described in current literature. This patient is currently alive, and a revision of his left anterior descending artery intervention was found to be unwarranted on repeat coronary angiography.

RESUMO

OBJECTIVE: This study aimed to determine athletic trainer compliance with emergency medicine and athletic training evidence-based guidelines for the on-the-field management of common pediatric sports-related injury and illness. METHODS: A questionnaire was distributed electronically to selected members of the National Athletic Trainer Association. The questionnaire included 10 clinical scenarios describing common sports-related injury/illness (closed head injury, cervical spine injury, blunt chest injury, blunt abdominal injury, ankle injury, knee injury with laceration, heat-related illness). On-the-field management decisions for each scenario were compared with selected emergency medicine and athletic training guidelines. RESULTS: Analysis was performed on 564 completed questionnaires (9% response rate). Responders were compliant with practice guidelines for both emergency medicine and athletic training except for blunt chest trauma with tachycardia, closed head injury with loss of consciousness, closed head injury with repetitive speech, closed head injury with a fall higher than 5 feet, cervical spine injury with paresthesias, and heat-related illness with persistent symptoms. Discrepancies between emergency medicine and athletic training guidelines included closed head injury with repetitive speech, closed head injury and height of fall, closed head injury and unequal pupils, and cervical spine injury with neck pain and paresthesias. CONCLUSIONS: Based on our sample, athletic trainers were compliant with many guidelines supported by both emergency medicine and athletic training. We identified several deficiencies in the availability of evidence-based guidelines and discrepancies between these guidelines and athletic trainer responses. To provide optimal care to pediatric athletes who sustain injury or illness, emergency medicine and athletic training organizations should collaborate to improve these discrepancies.

RESUMO

This study aimed to evaluate the impact of the COVID-19 pandemic on adults with opioid-treated chronic low back pain (CLBP), an understudied area. Participants in a "parent" clinical trial of non-pharmacologic treatments for CLBP were invited to complete a one-time survey on the perceived pandemic impact across several CLBP- and opioid therapy-related domains. Participant clinical and other characteristics were derived from the parent study's data. Descriptive statistics and latent class analysis analyzed quantitative data; qualitative thematic analysis was applied to qualitative data. The survey was completed by 480 respondents from June 2020 to August 2021. The majority reported a negative pandemic impact on their life (84.8%), with worsened enjoyment of life (74.6%), mental health (74.4%), pain (53.8%), pain-coping skills (49.7%), and finances (45.3%). One-fifth (19.4%) of respondents noted increased use of prescribed opioids; at the same time, decreased access to medication and overall healthcare was reported by 11.3% and 61.6% of respondents, respectively. Latent class analysis of the COVID-19 survey responses revealed 2 patterns of pandemic-related impact; those with worse pandemic-associated harms (n = 106) had an overall worse health profile compared to those with a lesser pandemic impact. The pandemic substantially affected all domains of relevant health-related outcomes as well as healthcare access, general wellbeing, and financial stability among adults with opioid-treated CLBP. A more nuanced evaluation revealed a heterogeneity of experiences, underscoring the need for both increased overall support for this population and for an individualized approach to mitigate harms induced by pandemic or similar crises.

RESUMO

INTRODUCTION: Understanding the presence and function of a diverse lung microbiome in acute lung infections, particularly ventilator-associated pneumonia (VAP), is still limited, evidencing significant gaps in our knowledge. AREAS COVERED: In this comprehensive narrative review, we aim to elucidate the contribution of the respiratory microbiome in the development of VAP by examining the current knowledge on the interactions among microorganisms. By exploring these intricate connections, we endeavor to enhance our understanding of the disease's pathophysiology and pave the way for novel ideas and interventions in studying the respiratory tract microbiome. EXPERT OPINION: The conventional perception of lungs as sterile is deprecated since it is currently recognized the existence of a diverse microbial community within them. However, despite extensive research on the role of the respiratory microbiome in healthy lungs, respiratory chronic diseases and acute lung infections such as pneumonia are not fully understood. It is crucial to investigate further the relationship between the pathophysiology of VAP and the pulmonary microbiome, elucidating the mechanisms underlying the interactions between the microbiome, host immune response and mechanical ventilation for the development of VAP.

RESUMO

RESUMEN La torsión anexial es secundaria a quistes ováricos generalmente benignos. La cirugía habitual es la salpingooferectomía. Sin embargo, para mantener la función ovárica se recomienda una cirugía mínimamente invasiva con detorsión y conservación del ovario independientemente de su apariencia. Presentamos el caso de una mujer de 19 años con diagnóstico de quiste a pedículo torcido, a quien se realizó detorsión laparoscópica del pedículo torcido y exéresis del quiste paratubárico con preservación de ovario, a pesar del aspecto isquémico. La paciente presentó evolución favorable y participó en un programa de ovodonación, obteniéndose ovocitos del ovario antes afectado en cantidad y calidad similar al ovario no afectado. La detorsión ovárica laparoscópica y conservación del ovario comprometido independientemente de su apariencia es un procedimiento seguro y eficaz para preservar la fertilidad.

RESUMO

RESUMEN La tuberculosis es una de las principales causas de muerte generada por un agente infeccioso a nivel mundial. Generalmente su afectación es pulmonar, pero bajo ciertas circunstancias puede diseminarse a través de vía linfática o sanguínea y afectar tejidos u órganos distantes. En el embarazo puede ocasionar múltiples complicaciones maternas y neonatales. A pesar de ser un problema importante de salud pública, en la actualidad no existe suficiente evidencia en las guías sobre la epidemiologia, flujograma diagnóstico y tratamiento de la tuberculosis genital en el embarazo. Se presenta un caso de tuberculosis genital en el tercer trimestre del embarazo con evolución tórpida, dificultad para el diagnóstico y retraso en la instauración del tratamiento.

ABSTRACT Tuberculosis is one of the main causes of death generated by an infectious agent worldwide. It usually affects the lungs, but under certain circumstances it can spread through the lymphatic or blood routes and affect distant tissues or organs. In pregnancy it can cause multiple maternal and neonatal complications. Despite being an important public health problem, there is currently insufficient evidence in the guidelines on the epidemiology, diagnostic flow chart and treatment of genital tuberculosis in pregnancy. A case of genital tuberculosis in the third trimester of pregnancy with a torpid evolution is presented, with difficulty in diagnosis and delay in the establishment of treatment.

RESUMO

Humans did not arrive on most of the world's islands until relatively recently, making islands favorable places for disentangling the timing and magnitude of natural and anthropogenic impacts on species diversity and distributions. Here, we focus on Amazona parrots in the Caribbean, which have close relationships with humans (e.g., as pets as well as sources of meat and colorful feathers). Caribbean parrots also have substantial fossil and archaeological records that span the Holocene. We leverage this exemplary record to showcase how combining ancient and modern DNA, along with radiometric dating, can shed light on diversification and extinction dynamics and answer long-standing questions about the magnitude of human impacts in the region. Our results reveal a striking loss of parrot diversity, much of which took place during human occupation of the islands. The most widespread species, the Cuban Parrot, exhibits interisland divergences throughout the Pleistocene. Within this radiation, we identified an extinct, genetically distinct lineage that survived on the Turks and Caicos until Indigenous human settlement of the islands. We also found that the narrowly distributed Hispaniolan Parrot had a natural range that once included The Bahamas; it thus became "endemic" to Hispaniola during the late Holocene. The Hispaniolan Parrot also likely was introduced by Indigenous people to Grand Turk and Montserrat, two islands where it is now also extirpated. Our research demonstrates that genetic information spanning paleontological, archaeological, and modern contexts is essential to understand the role of humans in altering the diversity and distribution of biota.

RESUMO

OBJECTIVES: This study aimed to analyze pediatric referrals for definite or possible appendicitis, to compare clinical predictors and laboratory values between patients with and without a final diagnosis of appendicitis, and to determine the accuracy of prereferral diagnostic interpretations of computed tomography scans, ultrasound, and magnetic resonance imaging modalities. METHODS: We conducted a retrospective analysis of pediatric patients referred from 2015 to 2019 to a tertiary care children's emergency department with definitive or possible appendicitis. Data abstracted included patient demographics, clinical symptoms, physical examination findings, laboratory results, and diagnostic imaging findings (by the referring center and the pediatric radiologist at the accepting center). An Alvarado and Appendicitis Inflammatory Response (AIR) score was calculated for each patient. RESULTS: Analysis was performed on 381 patients; 226 (59%) had a final diagnosis of appendicitis. Patients with appendicitis were more likely to have symptoms of nausea ( P < 0.0001) and vomiting ( P < 0.0001), have a higher mean temperature ( P = 0.025), right lower quadrant abdominal pain to palpation ( P = <0.0001), rebound tenderness ( P < 0.0001), a higher mean Alvarado score [5.35 vs 3.45 ( P < 0.0001)], and a higher mean AIR score [4.02 vs 2.17 ( P < 0.0001)]. Of the 97 diagnostic images initially interpreted as appendicitis by the referring center, 10 (10.3%) were read as no evidence of appendicitis. Of the 62 diagnostic images initially interpreted as "possible appendicitis" by the referring center, 34 (54.8%) were read as no evidence of appendicitis. Of those diagnostic images initially interpreted as "appendicitis" or "possible appendicitis" by the referring center, 24/89 (27.0%) of computed tomography scans, 17/62 (27.4%) of ultrasounds, and 3/8 (37.5%) of magnetic resonance imaging results were read as no evidence of appendicitis. CONCLUSIONS: Usage of established scoring algorithms, such as Alvarado and AIR, may decrease the unnecessary cost of diagnostic imaging and transfer to tertiary care. Virtual radiology consultations may be 1 potential solution to improve the referral process for pediatric appendicitis if initial interpretation is uncertain.

RESUMO

BACKGROUND: The impact of cirrhosis and portal hypertension on perioperative outcomes of minimally invasive left lateral sectionectomies remains unclear. We aimed to compare the perioperative outcomes between patients with preserved and compromised liver function (noncirrhotics versus Child-Pugh A) when undergoing minimally invasive left lateral sectionectomies. In addition, we aimed to determine if the extent of cirrhosis (Child-Pugh A versus B) and the presence of portal hypertension had a significant impact on perioperative outcomes. METHODS: This was an international multicenter retrospective analysis of 1,526 patients who underwent minimally invasive left lateral sectionectomies for primary liver malignancies at 60 centers worldwide between 2004 and 2021. In the study, 1,370 patients met the inclusion criteria and formed the final study group. Baseline clinicopathological characteristics and perioperative outcomes of these patients were compared. To minimize confounding factors, 1:1 propensity score matching and coarsened exact matching were performed. RESULTS: The study group comprised 559, 753, and 58 patients who did not have cirrhosis, Child-Pugh A, and Child-Pugh B cirrhosis, respectively. Six-hundred and thirty patients with cirrhosis had portal hypertension, and 170 did not. After propensity score matching and coarsened exact matching, Child-Pugh A patients with cirrhosis undergoing minimally invasive left lateral sectionectomies had longer operative time, higher intraoperative blood loss, higher transfusion rate, and longer hospital stay than patients without cirrhosis. The extent of cirrhosis did not significantly impact perioperative outcomes except for a longer duration of hospital stay. CONCLUSION: Liver cirrhosis adversely affected the intraoperative technical difficulty and perioperative outcomes of minimally invasive left lateral sectionectomies.

RESUMO

BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR) is the ratio between neutrophil and lymphocyte counts measured in peripheral blood. NLR is easily calculable based on a routine blood test available worldwide and may reflect systemic inflammation. However, the relationship between NLR and clinical outcomes in atrial fibrillation (AF) patients is not well-described. METHODS: We calculated NLR at baseline in ENGAGE AF-TIMI 48, a randomized trial comparing edoxaban versus warfarin in patients with AF followed for 2.8 years (median). The association of baseline NLR with major bleeding events, major adverse cardiac events (MACE), cardiovascular death, stroke/systemic embolism, and all-cause mortality were calculated. RESULTS: The median baseline NLR in 19,697 patients was 2.53 (interquartile range 1.89-3.41). NLR was associated with major bleeding events (HR 1.60; 95% CI 1.41-1.80), stroke/systemic embolism (HR 1.25; 95% CI, 1.09-1.44), MI (HR 1.73; 95% CI 1.41-2.12), MACE (HR 1.70; 95% CI 1.56-1.84), CV (HR 1.93; 95% CI 1.74-2.13) and all-cause mortality (HR 2.00; 95% CI 1.83-2.18). The relationships between NLR and outcomes remained significant after adjustment for risk factors. Edoxaban consistently reduced major bleeding. MACE, and CV death across NLR groups vs. warfarin. CONCLUSIONS: NLR represents a widely available, simple, arithmetic calculation that could be immediately and automatically reported during a white blood cell differential measurement to identify patients with AF at increased risk of bleeding, CV events, and mortality.
