BACKGROUND: Rising health care costs necessitate a reassessment of routine preoperative practices. Despite low transfusion rates in elective colorectal operations, many hospitals continue to perform routine preoperative type and screen testing. OBJECTIVE: To assess perioperative blood transfusion rates and determine preoperative and surgical factors associated with transfusions to determine whether the routine preoperative type and screen testing are necessary for elective abdominal colorectal surgeries, particularly in the setting of minimally invasive surgery. DESIGN: Retrospective cohort study. SETTINGS: Mayo Clinic, 2019–2023. PATIENTS: Adult patients undergoing elective abdominal colorectal operations. Exclusion criteria included emergent operations and nonabdominal procedures. INTERVENTIONS: None. MAIN OUTCOME MEASURES: The primary outcome was the incidence of intraoperative and immediate postoperative (≤72 hours) blood product transfusion. Secondary outcomes assessed associations between transfusion rates, surgical approach, and preoperative variables. RESULTS: Among 4652 patients, 2770 underwent minimally invasive surgery and 1882 underwent open procedures. Perioperative red blood cell transfusion rates were lower in minimally invasive procedures (3.0% colectomy, 4.5% proctectomy) compared to open procedures (8.7% colectomy, 21.5% proctectomy). Open proctectomy was the strongest predictor of transfusion (OR 12.05; 95% CI, 8.94–16.26; p < 0.0001) followed by open colectomy (OR 2.59; 95% CI, 2.04–3.30; p < 0.0001). Preoperative factors including ASA class IV (OR 5.21; 95% CI, 1.09–24.82; p < 0.0382) and anemia (OR 4.14; 95% CI, 3.09–5.55; p < 0.0001) were also significantly associated with red blood cell transfusion. LIMITATIONS: The retrospective nature of the study may introduce selection bias. In addition, institutional practice patterns may limit the generalizability of findings. CONCLUSIONS: Patients undergoing elective minimally invasive colorectal surgery have very low rates of perioperative blood transfusions; thus, routine preoperative type and screen testing is likely unnecessary for this patient cohort. However, patients undergoing planned open operations, likely due to procedural complexity, and those who are ASA class IV, have preoperative anemia, or have anal cancer have higher transfusion risks and may benefit from selective testing. Implementing a risk-stratified approach based on surgical technique and patient comorbidities could potentially reduce unnecessary testing and associated health care costs. See Video Abstract. RE-TIPIFICACIÓN Y EVALUACIÓN PREOPERATORIAS: CÓMO IDENTIFICAR CUÁNDO ES NECESARIA UNA CIRUGÍA COLORRECTAL ELECTIVA ANTECEDENTES: El aumento en los costos de la atención médica exigen la reevaluación de las practicas preoperatorias de rutina. A pesar de las bajas tasas de transfusión en la cirugía colorrectal electiva, muchos hospitales continúan realizando pruebas de tipo y de cribado preoperatorios de forma rutinaria. El poresente estudio evalúa las tasas de transfusiones sanguíneas perioperatorias e identifica los factores asociados con éstas transfusiones para determinar la necesidad de pruebas de tipo y de cribado preoperatorios de forma rutinaria en cirugías colorrectales abdominales electivas. OBJETIVO: Evaluar las tasas de transfusión sanguínea perioperatoria y determinar los factores preoperatorios y quirúrgicos asociados con las transfusiones, con el fin de determinar si las pruebas de tipo y de cribado preoperatorias de forma rutinaria son necesarias en cirugías colorrectales abdominales electivas, en particular en el contexto de la cirugía mínimamente invasiva. DISEÑO: Estudio de cohortes retrospectivo. ESCENARIO: Clínica Mayo, 2019-2023. PACIENTES: Pacientes adultos sometidos a cirugías colorrectales abdominales electivas. Los criterios de exclusión incluyeron operaciones de emergencia y procedimientos no abdominales. INTERVENCIONES: Ninguna. PRINCIPALES MEDIDAS DE RESULTADOS: El resultado primario fue la incidencia de transfusión de hemoderivados intraoperatoriamente y postoperatoria inmediata (≤72 horas). Los resultados secundarios evaluaron la asociación entre las tasas de transfusión, el abordaje quirúrgico y las variables preoperatorias. RESULTADOS: De 4652 pacientes, 2770 se sometieron a cirugía mínimamente invasiva y 1882 a laparotomía. Las tasas de transfusión eritrocitaria perioperatoria fueron menores en los procedimientos mínimamente invasivos (3,0 % colectomía, 4,5 % proctectomía) que en los procedimientos abiertos (8,7 % colectomía, 21,5 % proctectomía). La proctectomía abierta fue el predictor más sólido de transfusión (OR: 12,05; IC del 95 %: 8,94-16,26; p < 0,0001), seguida de la colectomía abierta (OR: 2,59; IC del 95 %: 2,04-3,30; p < 0,0001). Los factores preoperatorios, incluyendo la clase ASA IV (OR 5,21; IC del 95 %: 1,09-24,82; p < 0,0382) y la anemia (OR 4,14; IC del 95 %: 3,09-5,55; p < 0,0001), también se asociaron significativamente con la transfusión de glóbulos rojos. LIMITACIONES: La naturaleza retrospectiva del estudio puede introducir sesgo de selección. Además, los patrones de práctica institucional pueden limitar la generalización de los hallazgos. CONCLUSIONES: Los pacientes sometidos a cirugía colorrectal mínimamente invasiva electiva tienen tasas muy bajas de transfusiones sanguíneas perioperatorias, por lo que las pruebas de detección y tipo de sangre preoperatorias de rutina probablemente sean innecesarias para esta cohorte de pacientes. Sin embargo, los pacientes sometidos a cirugías abiertas planificadas, probablemente debido a la complejidad del procedimiento, y aquellos con clase ASA IV, anemia preoperatoria o cáncer anal, tienen mayor riesgo de transfusión y podrían beneficiarse de pruebas selectivas. La implementación de un enfoque estratificado por riesgo basado en la técnica quirúrgica y las comorbilidades del paciente puede reducir las pruebas innecesarias y los costos de atención médica asociados.

Abstract Background and Objectives Lucid episodes (LEs) in people living with late-stage dementia have been reported anecdotally. However, how this seemingly unexpected phenomenon is experienced by family caregivers is less known. Focusing on the two most common groups of informal caregivers, spouses and adult children, this study examined variability in family caregivers’ experiences with LEs—whether they exhibit differential appraisals of and responses to LEs. Research Design and Methods Using a sample of former/bereaved and current family caregivers from UsAgainstAlzheimer’s A-LIST, we conducted an online survey of spouse and child caregivers (N = 387). We conducted semistructured interviews among a subset of caregivers who witnessed a LE (n = 22). Results Overall, child caregivers were more likely to witness a LE than spouse caregivers. Among former/bereaved caregivers who witnessed a LE (n = 139), spouses were likely to report nonverbal communication during LEs, appraise LEs more negatively, and make changes in care decisions, such as end-of-life planning and financial decisions, compared to adult children. Among current caregivers who witnessed a LE (n = 80), spouses often reported no special circumstances preceding LEs, whereas children linked LEs to friend/family visits. No significant differences were found in positive and negative appraisals of LEs between current spouse and child caregivers. Content analysis of qualitative interviews revealed the contexts underlying these differences. Discussion and Implications Differences between spouses and adult children in their experiences with LEs are related to their different caregiving contexts, including relationship history, living arrangements, expectations, motivations, and caregiving resources.

Abstract Background Hospital‐at‐home programs (HaH) in the United States have evolved to include a virtual‐hybrid delivery model, where all physician encounters are virtual and partnered with a home care team. Objective To examine whether a virtual hybrid HaH program enabled by technology has similar clinical outcomes to traditional brick‐and‐mortar (B&M) hospital care. Methods We conducted a pragmatic trial at three hospitals, randomizing 1150 acutely ill patients requiring hospital care between July 10, 2023, and October 31, 2023 one‐to‐one into two groups: intervention (HaH) and control (B&M). The primary analysis was an intention‐to‐treat non‐inferiority analysis of the primary outcome, which was a composite of 30‐day all‐cause mortality and unplanned readmissions. Secondary outcomes included 30‐day readmission, all‐cause mortality, and patient experience. Results The mean age was 67.8 (standard deviation [SD] 16.3) years, and 52.2% were female. The primary outcome occurred in 99 (17.3%) HaH patients and 114 (19.8%) B&M patients (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.63–1.14, p = .28), meeting the non‐inferiority criterion. Thirty‐day unplanned readmission occurred in 84 (14.7%) HaH patients and 101 (17.5%) B&M patients (OR 0.81, 95% CI 0.59–1.11, p = .19). Thirty‐day all‐cause mortality occurred in 25 (4.4%) HaH patients and 19 (3.3%) B&M patients (OR 1.34, 95% CI 0.73–2.46, p = .35). No HaH patients died while receiving their hospital care at home. HaH program was associated with a higher likelihood of patients reporting feeling extremely comfortable or very comfortable (84.4% HaH; 60.9% B&M, p = .001). Conclusion A hybrid HaH model is a safe and comfortable alternative to traditional B&M hospital care.

Objectives: Surgical site infections (SSIs) are the most common hospital-acquired infections in the United States, of which methicillin-resistant Staphylococcus aureus (MRSA) accounts for 43%. Preoperative povidone-iodine nasal swab (PNS) is considered an effective and cost-saving treatment for Staphylococcus aureus decolonization. We aim to assess the impact of preoperative PNS on SSI incidence. Materials and Methods: This retrospective observational study utilized elective surgical cases between January 1, 2018 and May 31, 2023, at a single academic medical center. The cohort was divided into PNS and no PNS groups. The cohort was propensity-matched, and Pearson χ2/Kruskal-Wallis tests were performed to compare group differences. Multivariable logistic regression was utilized to compare events between cohorts before and after matching. An alpha of <0.05 was considered significant. Results: A total of 45,998 (22,999 per group) matched participants were evaluated. On multivariate regression, the non-PNS treatment group was associated with an increase in hospital overall SSI occurrence (OR: 1.48, P = 0.02) but not specifically in-hospital methicillin-sensitive Staphylococcus aureus SSI, MRSA-SSI, or any 30-day SSI (P > 0.05). Compared with PNS treatment and prophylactic antibiotics, in-hospital SSI was higher in the absence of PNS treatment (OR: 1.83, P < 0.001), antibiotic (OR: 2.63, P < 0.001), or both (OR: 2.06, P < 0.01). Compared with PNS treatment plus prophylactic antibiotic, in-hospital MRSA-SSI was only higher in the absence of antibiotic (OR: 2.92, P < 0.01) treatment. Conclusions: Preoperative treatment with PNS may reduce overall in-hospital SSI but has no independent impact on MRSA SSI.

Background: Patients with severe and life-limiting illnesses transitioning out of the hospital often rely on family caregivers (FCGs) to manage communication with health care teams during hospitalizations and outpatient care. However, FCGs infrequently receive adequate training or support to prepare for these responsibilities. Effective communication between FCGs and health care teams is critical for preparing FCGs and reducing risks for poor outcomes. This study tested an eight-week intervention to improve FCG preparedness and communication practices during transitions out of the hospital. Methods: Conducted from 2018 to 2022, this randomized controlled trial included adult FCGs in rural areas in the United States (Minnesota, Wisconsin, and Iowa). FCGs caring for adults who received inpatient palliative care and were transitioning out of the hospital were eligible. The intervention group received teaching, guidance, and counseling from a palliative care nurse interventionist via video visits before and for eight weeks after discharge. The control group received monthly phone calls but no intervention. Outcomes included changes in FCG-reported preparedness for caregiving and communication with health care teams. Results: Of the 429 consented, 367 (183 intervention and 184 control participants) initiated the intervention; 164 had complete preparedness data, and 161 had complete communication data at baseline and eight weeks. In unadjusted analyses, the intervention group showed statistically significant improvements in preparedness but not communication practices. After adjusting for factors associated with care transitions, the findings persisted. Conclusion: Partnering rural FCGs with palliative care nurses via video can improve caregiver preparedness during care transitions. Improving communication practices may need more targeted strategies.

Background Heart failure self‐care can contribute to a high daily workload and treatment burden. The goal of this cohort study was to assess the characteristics and outcomes associated with burden of treatment (BoT). Methods Surveys comprising validated instruments to measure BoT and other constructs were mailed to patients with heart failure in Southeastern Minnesota. Participants were divided into tertiles by BoT scores. Associations of clinical variables with BoT were examined using multinomial logistic regression. Associations of BoT with mortality and hospitalizations were examined using Cox proportional hazard regression and Andersen–Gill models, respectively. Results A total of 609 participants (mean age 76.3 years, 60.3% men, 55.2% urban, 64.3% preserved ejection fraction) completed surveys. Higher BoT was associated with worse health status, more depressive symptoms, lower resilience, less social support, lower medication adherence, and worse health literacy. Mean±SD follow‐up was 14.4 (4.1) months. Estimated 1‐year mortality (8.3% [95% CI, 4.3%–12.1%], 11.0% [95% CI, 6.5%–15.2%], 16.0% [95% CI, 10.8%–21.0%]) and 1‐year mean cumulative hospitalizations (0.57 [95% CI, 0.45–0.72], 0.83 [95% CI, 0.66–1.05], 1.15 [95% CI, 0.93–1.42]) increased across patients reporting low, medium, and high BoT, respectively. Adjustment for health status eliminated any significant association of BoT with risks of death and hospitalization (adjusted hazard ratio [HR], 1.10 [95% CI, 0.58–2.07] and 1.09 [95% CI, 0.74–1.61], respectively, highest versus lowest BoT tertile). Conclusions BoT in heart failure varies by clinical and psychosocial factors. Higher BoT identifies patients at increased risk of adverse health outcomes due to their worse health status. These findings can serve as a foundation for interventions to minimize workload and improve quality of life.

Abstract IntroductionFungal infections, particularly in the Midwest, can often be asymptomatic and may mimic primary lung cancer. This case illustrates pulmonary histoplasmosis in an 80-year-old woman with a history of lung cancer highlighting the diagnostic challenges presented when both conditions coexist.Case SummaryAn 80-year-old woman (prior smoking history of 47-pack-years) with synchronous lung cancers (poorly differentiated non-small cell carcinoma with squamous differentiation in the left lower lobe and squamous cell carcinoma in the right lower lobe) previously underwent radiation therapy to both lesions. She was admitted for shortness of breath and cough and was initially diagnosed with pneumonia based on CT findings. Despite multiple courses of antibiotics, her symptoms persisted over 2 months, improving only temporarily with a short course of prednisone. A follow-up CT revealed increasing confluent thick-walled cavitation in the posterior right upper lobe and superior segment of the right lower lobe concerning for cavitating/necrotizing pneumonia versus possible cancer progression. A PET-CT scan (Fig.1A) showed significant FDG uptake in the right upper lobe lesion and mild uptake in mediastinal lymph nodes complicating the differentiation between cancer and infection. Bronchoscopy with biopsy of an endobronchial lesion in the posterior segment of right lower lobe revealed necrotizing granulomatous inflammation (Fig.1B) with GMS stain showing the presence of fungal organisms suggestive of histoplasmosis. Histoplasma PCR from bronchoalveolar lavage was also positive. She was subsequently started on antifungal therapy for a planned one-year treatment course. DiscussionHigh positron emission tomography (PET) avidity in chest imaging is often linked to aggressive tumors but can also indicate benign conditions such as fungal infections. A “flip-flop sign” on PET imaging, where nodal activity surpasses that of a lung nodule, is typically seen in benign lung lesions, particularly fungal infections. However, infections and inflammatory conditions may also show high PET avidity mimicking malignancy. Endobronchial lesions, common in lung cancer, are less frequently associated with infections. In patients with a history of cancer, active lung infection, and PET-avid lesions without the flip-flop sign, invasive testing is usually required to differentiate between infection and malignancy. In this case, our patient with a history of lung cancer and a PET-avid lung lesion was found to have pulmonary histoplasmosis after invasive testing highlighting the need for comprehensive evaluation.ConclusionThis case emphasizes the importance of considering fungal infections in the differential diagnosis of PET-avid pulmonary lesions, particularly in patients with a history of malignancy.

Abstract Rational: Talc pleurodesis is an effective intervention for preventing recurrent pleural effusions and pneumothoraces, particularly in non-surgical candidates. Due to its efficacy and safety, it is recommended as the most effective sclerosant for pleurodesis. However, in some cases, the initial pleurodesis fails, necessitating a repeat procedure. The efficacy of repeat talc pleurodesis after an initial failure is an area that requires further exploration. This study explores the safety and efficacy of repeat talc pleurodesis among patients who did not respond to the initial intervention. Methods: This retrospective study analyzed hospitalized patients who underwent 4g talc slurry pleurodesis from 2019 to 2024, focusing on demographics, comorbidities, initial pleurodesis failure, and recurrence rates. Pleurodesis failure was identified by lung sliding, recurrent effusion, or pneumothorax during the same hospitalization. The primary outcome was recurrence post-discharge, assessed by pleural effusion or pneumothorax within 180 days post-repeat pleurodesis. Results: This study included 94 patients (52.1% male, 47.9% female) with a mean age of 67.6. Among them, 79 (84%) received a single 4g dose of talc, while 15 (16%) received multiple 4g talc doses for initial pleurodesis. Recurrence occurred in 20 (25.3%) of the single-dose group and 1 (6.7%) of the multiple-dose group within 180 days, though the difference was not statistically significant (p=0.112). Recurrence-free rates were 93.6% at 30 days, 85.1% at 90 days, and 77.7% at 180 days. Of the 20 patients with recurrence after a single 4g dose of talc, 8 (40%) underwent repeat pleurodesis, with only one recurrence requiring surgical intervention. Additionally, there was no recurrence after repeat talc pleurodesis in the one patient with recurrence after receiving multiple 4g talc doses for initial pleurodesis. No associations were found between recurrence rates and factors like gender (p=0.213) or comorbidities (emphysema, COPD, lung malignancy). Chest pain was a common complaint, but no cases of respiratory distress were reported post-pleurodesis. Conclusion: The efficacy of initial talc pleurodesis (77.7%-93.6%) in this cohort aligns with existing literature. Multiple-dose talc pleurodesis effectively prevented recurrence in 93.3% of patients, with no reported respiratory distress. Additionally, repeat talc pleurodesis was successful in 87.5% of those with recurrence after an initial single 4g dose. These findings support multiple-dose talc pleurodesis and repeat talc pleurodesis as safe and effective options for preventing recurrence post-initial failure and post-repeat talc pleurodesis, respectively. Although no significant recurrence predictors were identified, future research could focus on patient-specific factors to enhance treatment selection and optimize outcomes.

Abstract A 77-year-old female with history of a right lower lobe adenocarcinoma (pT1a, pN0) underwent right lower lobectomy in August 2023, which subsequently was complicated by a bronchopleural fistula at the level of the right lower lobe bronchial stump. This led to a chronic hydropneumothorax, including a fungal empyema requiring placement of a 14-French thoracostomy tube and prolonged antimicrobial treatment over the next year. In June 2024 she underwent bronchoscopy, with application of argon plasma coagulation (APC) to cauterize the immediate area abutting the bronchopleural fistula and Gore VBX stent placement from the bronchus intermedius to the right middle lobe bronchus, bypassing the right lower lobe bronchial stump. There was no air leak immediately after that procedure and she continued with a 14-French thoracostomy tube in place for empyema drainage. Unfortunately, within the next 10 days the stent migrated requiring replacement. About a month later in July, 2024 the second stent was removed and revealed a persistent defect at the level of the bronchial stump with no apparent regression in size relative to the images captured prior to the initial bronchial stent placement. Under the expanded access pathway, a size 5 Spiration endobronchial valve was placed within the fistula in the right lower lobe bronchial stump (Figure 1). At the conclusion of the bronchoscopy procedure, a recruitment maneuver was performed while the suction on the thoracostomy tube was briefly increased to -40 cm H2O suction and no air leak was evident. The next CT chest 2 weeks later showed substantial improvement of the right hydropneumothorax. The air leak never returned and the thoracostomy tube was removed once the fluid drainage became negligible. The patient's dyspnea gradually improved and she was able to wean off supplemental oxygen. A follow-up CT chest 3 months later demonstrated a very small residual right pleural effusion with no gas component and stable positioning of the endobronchial valve. The multidisciplinary team involved in the patient's care intend to maintain the endobronchial valve in position indefinitely.

Abstract Rationale: Airway-stenosing disease is a significant clinical problem in multiple populations. While the immediate endoscopic and clinical response to bronchoscopic interventions are high, rates of clinically significant recurrence are elevated, and often require multiple and frequent reinterventions. Newer strategies to prevent recurrence of central and proximal airway stenosis are needed. Methods: Retrospective review of bronchoscopic balloon bronchoplasties performed at the Mayo Clinic utilizing paclitaxel coated balloons (PCB) in 2023-2024 for recurrent airway stenosis. IN.PACT Admiral and AV balloons (sizes 5-12 mm, 3.5 mcg/mm2 paclitaxel dose) were used with an inflation time of 2-3 minutes. Procedural success was defined as &lt;50% airway stenosis or resolution of the procedural indication. Reintervention was considered only if a therapeutic bronchoscopy was subsequently required to address the same lesion treated with PCB. Only patients with follow-ups &gt;90 days were included in the reintervention inter-procedural time analysis. Results: Thirty-three procedures were performed in 18 patients. Seventeen (51%) for lung transplantation-associated stenosis (29% anastomotic/perianastomotic, 76% lobar and segmental stenoses), 8 (24%) for granulomatous polyangiitis-associated stenosis, 3 for postintubation tracheal stenosis and 2 for chemical/pill injury. Eighteen cases (54%) utilized an additional dilation modality (12 non-coated balloon dilation, 4 rigid dilation), 5 spray cryotherapy, 6 other ablative therapies (4 CO2-laser, 2 electrocautery cuts), and 6 received an airway stent during the same procedure. 57% percent of interventions occurred in the lobar, 27% mainstem/bronchus intermedius, 9% tracheal, 7% segmental airways. Thirty-one (93%) cases had a satisfactory initial endoscopic result. The median number of bronchoscopic therapeutic interventions required before the use pf PCB was 5 (IQR 2.5-11.5), which significantly decreased to 0.1 (IQR 0-1, range 0-9) after PCB (p &lt;0.001). The reintervention-free survival significantly increased after PCB dilation from a median 35 days (IQR 28.7-80.5) to 132 days (IQR 64-197; p=0.004). Twenty-one cases required subsequent bronchoscopies, sixteen (76%) of which demonstrated improvement in lesion severity when compared to the results of prior interventions. Only 16 (48%) required therapeutically addressing the same lesion. Only 2 minor complications occurred (6%, self-limited bleeding and unplanned admission), none related to paclitaxel use. Six-month mortality was 3% from an unrelated cause. Conclusions: The locoregional antiproliferative effects of paclitaxel show promise in preventing recurrence, minimizing the need for repeat procedures, and extending intervals between interventions in patients with recurrent, predominantly benign airway stenosis. Its use is feasible, safe, and future research is warranted, particularly comparing PCB with the currently available strategies.
