RESUMO
Background: To evaluate the occurrence of malnutrition in pulmonary embolism (PE)-related hospitalisations and assess the impact of malnutrition on the outcomes of patients with PE. Methods: A retrospective observational study using data extracted from the Nationwide Inpatient Sample from 2016 to 2018. Hospitalisations with a principal diagnosis of PE were obtained using International Classification of Diseases, Tenth Revision codes and divided into groups based on a secondary diagnosis of malnutrition. Results: Of 563 135 PE hospitalisations, 30 495 (5.4%) had malnutrition. PE patients with malnutrition were older (mean age±SD, 69.1±14.5 vs 62.3±16.6, p<0.001) and with higher Charlson Comorbidity Index score (3 to 5, 24.8% vs 12.9%, p<0.001). Concurrent malnutrition was associated with higher adjusted OR (aOR) of in-hospital mortality (aOR 2.43, 95% CI 2.18 to 2.70, p<0.001), acute kidney injury (aOR 1.56, 95% CI 1.45 to 1.67, p<0.001), sepsis (aOR 4.37, 95% CI 3.79 to 5.03, p<0.001), shock (aOR 2.52, 95% CI 2.25 to 2.81, p<0.001), acidosis (aOR 2.55, 95% CI 2.34 to 2.77, p<0.001) and mechanical ventilation (aOR 2.95, 95% CI 2.61 to 3.33, p<0.001). Patients with PE and malnutrition had an increased mean length of stay (adjusted difference 3.39 days, 95% CI 3.14 to 3.65, p<0.001), hospital charges (adjusted difference US$34 802.11, 95% CI US$31 005.01 to US$38 599.22, p<0.001) and costs (adjusted difference US$8 332.01, 95% CI US$7489.09 to US$9174.94, p<0.001). Conclusion: Concurrent PE and malnutrition were associated with worse outcomes. The study highlights the importance of identifying malnutrition in patients with PE to improve outcomes and reduce healthcare utilisation.
RESUMO
Background: Tracheobronchial stents are often used to manage lung transplant airway complications. In 2005, the Food and Drug Administration (FDA) issued a warning against the use of metallic stents for benign airway disease. Since that time, fully covered hybrid metallic stents have been developed and are increasingly used due to their ease of insertion and removal. There is limited data to support their safe utilization for transplant airway complications. This is the largest analysis to date of the safety of hybrid metallic stents for transplant airway complications. Methods: We performed a retrospective study of patients who had covered metallic stents placed for transplant airway complications between April 2016 to April 2021. Information obtained from chart review included demographics, procedure notes and stent data including indication for placement, type, size, location, duration, and complications. Results: We identified 50 patients who had a combined 376 stents placed for a total of 15,711 stent days. The most common minor complication and reason for removal was mucus plugging affecting 193 stents.There were only two cases of major stent associated complications. Among minor complications, there was a increased risk of stent fracture with Bonastent® (P=0.04). Conclusions: Our data shows that hybrid metallic stents are a safe intervention for patients with transplant airway complications. Most complications were minor and managed with repeat bronchoscopy. There were only two major complications over a 5-year period. Given the wide spectrum of possible airway complications, further research is needed to determine the optimal use of stents for patients with transplant airway complications.
RESUMO
Bariatric surgery (BAS) may result in adverse outcomes that include appearance of gastrointestinal (GI) symptoms and/or failure to reach the weight reduction goal. This retrospective study tested the hypothesis that pre-operative gastric emptying (GE) abnormality is responsible for adverse post-surgical outcomes.Pre-operative GE was performed using the standard solid-meal GE scintigraphy (GES) in 111 consecutive patients (105 females and 6 males, mean age 46.2 years, range 20-70 years) who were evaluated for BAS. All underwent BAS - 93 had laparoscopic sleeve gastrectomy (LSG) and 18 had Roux-en-Y (ReY) gastric bypass. All had short-term (3-6 months) and long-term (up to 54 months) follow-up with review of symptoms, physical, and laboratory examinations. Chi-square analysis was performed. P-value < .05 was considered significant.Of the 111 patients, 83 had normal and 28 had abnormal pre-op GES. Sixty-eight were asymptomatic and 43 were symptomatic prior to surgery. Following surgery, 81 patients were asymptomatic and 30 were symptomatic at long-term follow-up. There was no significant difference between pre-op GE results and post-surgical adverse clinical outcome (pâ=âns). However, GES results seem to have guided the selection of surgical procedure significantly (Pâ=â.008).Pre-operative GE study was not a strong predictor of clinical outcome in BAS. Although, it influenced the type of surgery, as when the GES was abnormal, the patient was more likely to undergo ReY and when GES was normal, they favored LSG. Interestingly, many of our symptomatic patients at 6 months post-op were asymptomatic after long-term follow-up.
