Background: Effective communication and collaboration among clinical and nonclinical staff are critical to the health and safety of the staff, for optimal team performance and for safe patient care. While respiratory protective equipment are routine key strategies to protect healthcare workers from exposure to select respiratory pathogens, they have been demonstrated to disrupt speech intelligibility. The COVID-19 pandemic escalated the need for and utilization of respiratory protection in all healthcare settings. The purpose of this study was to evaluate the impact of various respiratory personal protection equipment (PPE) on speech intelligibility. Methods: Healthcare workers were invited to participate in audiology-based testing in which the audiologist read words from the Modified Rhyme Test (MRT) using two levels of background noise and rotating through six different types of respiratory PPE. Descriptive statistics and ANOVA were used for analysis. Findings: Modified Rhyme Test (MRT) scores were significantly lower when wearing the CleanSpace Halo (−10.22 points, 95% CI [−11.28, −9.20]) and the elastomeric half mask respirator (EHMR) with or without the exhalation valve filter (−2.28 points, 95% CI [−3.33, −1.20] and −3.22 points, 95% CI [−4.40, −2.18] respectively) after adjusting for noise level, listener respiratory PPE, and correlation within each participant. Conclusions/Applications to practice: Elastomeric half mask respirator (EHMR) decreased speech intelligibility compromising clear communications. Further research on respiratory PPE design is needed to optimize speech intelligibility and communication maximally.

Pediatric delirium (PD) is an acute neuropsychiatric syndrome marked by fluctuating disturbances in attention and cognition, frequently observed in pediatric intensive care units (PICUs) and associated with increased morbidity, mortality, and long-term cognitive impairment. Despite its clinical significance, PD remains underdiagnosed due to challenges inherent in assessing consciousness and cognition in children at varying developmental stages. Several bedside tools have been developed and validated in recent years, including the Cornell Assessment of Pediatric Delirium (CAPD), PreSchool Confusion Assessment Method for the Intensive Care Unit (psCAM-ICU); Pediatric Confusion Assessment Method for the Intensive Care Unit (pCAM-ICU), and Sophia Observation Withdrawal Symptoms—Pediatric Delirium Scale (SOS-PD), enhancing early recognition and management of PD in critically ill children. This narrative review explores the historical background, epidemiology, risk factors, pathophysiology, clinical subtypes, diagnostic tools, and current prevention and treatment strategies for PD from newborns to 21 years old. The screening tools available and the integration of non-pharmacological interventions, such as environmental modifications and family-centered care, as well as cautious and selective pharmacological management, are emphasized in this review. Early identification and targeted interventions are essential to mitigate the adverse outcomes associated with PD.

Fundamento: A angiotomografia computadorizada (ATC) com descarte triplo (TRO; do inglês, triple rule-out) é um protocolo sincronizado ao eletrocardiograma (ECG) que permite a avaliação simultânea das artérias coronárias, da aorta torácica e das artérias pulmonares em um único exame. É especialmente útil para pacientes com risco baixo a moderado de síndrome coronariana aguda no pronto atendimento, particularmente quando dissecção aórtica e embolia pulmonar também são consideradas no diagnóstico diferencial. Objetivo: O presente estudo visou comparar, em termos de dose de radiação e qualidade da imagem, dois protocolos de TRO: totalmente sincronizado ao ECG (protocolo A) e parcialmente sincronizado ao ECG (protocolo B), ambos incluindo cobertura da aorta abdominal. Tal comparação de protocolos pode ser útil quando algoritmos de reconstrução iterativa não estiverem disponíveis e a transição manual entre em protocolos parcialmente sincronizados ao ECG for necessária. Métodos: A dose de radiação foi avaliada usando o produto dose-comprimento, a dose efetiva e a dose virtual. Os valores de atenuação foram medidos nas artérias coronárias e pulmonares, bem como na aorta descendente e abdominal. A qualidade da imagem e a conspicuidade dos vasos foram avaliadas por meio de uma escala Likert de 5 pontos. Resultados: Um total de 56 pacientes foi incluído. O protocolo B demonstrou exposição à radiação significativamente menor em comparação ao protocolo A em todas as métricas: mediana do produto dose-comprimento (1,1 mSv [intervalo interquartil: 0,9 a 1,1] versus 2,2 mSv [intervalo interquartil: 1,6 a 2,8]), dose efetiva (17,0 mSv [intervalo interquartil: 14,3 a 18,1] versus 32,6 mSv [intervalo interquartil: 24,4 a 42,7]) e dose virtual (16,2 [intervalo interquartil: 9,3 a 20,4] versus 34,7 [intervalo interquartil: 19,9 a 43,5]). Todas as diferenças foram estatisticamente significativas (p < 0,001). Não houve diferenças significativas nas medidas de atenuação ou na avaliação qualitativa das imagens entre os dois protocolos. Conclusão: A ATC com TRO parcialmente sincronizada ao ECG proporciona qualidade de imagem comparável à técnica totalmente sincronizada ao ECG, reduzindo significativamente a exposição à radiação, tornando-se uma alternativa mais eficiente em termos de dose de radiação, quando algoritmos de reconstrução iterativa não estiverem disponíveis e a transição manual for necessária.

Abstract Background Primary aldosteronism (PA) is a common treatable cause of hypertension. When caused by unilateral adrenal disease, it is potentially curable by adrenalectomy. However, specialized tests and other factors may delay definitive treatment. We assessed the time to adrenalectomy (TTA) for patients worldwide. Methods We conducted an international, multicentre retrospective study involving 39 centres from 15 countries to determine the total time taken from the first presentation to adrenalectomy and the intervals between each stage (screening, confirmatory, subtyping, and adrenalectomy). We included patients with PA who underwent adrenalectomy from January 1, 2018, to October 30, 2022. Post-adrenalectomy outcomes were evaluated using the Primary Aldosteronism Surgery Outcome criteria. We performed multivariable quantile and linear regression to identify characteristics associated with longer TTA. Results We included 861 patients, mean age 49.3 ± 11.1 years, and 44.5% were women. Overall median TTA was 13.5 months, IQR: 6.6-24.5. Median intervals were 0.1 months (screening), 1.0 months (confirmatory), 4.1 months (subtyping), and 4.3 months (adrenalectomy). On multivariable analysis, median TTA was increased by 5.4 months for each additional adrenal vein sampling (AVS) procedure. Other factors associated with longer TTA included adrenalectomy post-COVID-19, younger age, and additional screening tests. Compared with countries with routine AVS, those without AVS had a shorter TTA (6.1 vs 15.1 months, P &lt; .001), but greater likelihood of absent/partial biochemical success post-adrenalectomy (27.4% vs 12.4%, P &lt; .001). Conclusion Primary aldosteronism management is time-consuming worldwide, especially for subtyping tests and adrenalectomy. While omitting AVS reduces overall time, patients are less likely to achieve biochemical cure post-adrenalectomy.

OBJECTIVE In many individuals, type 2 diabetes (T2D) remains poorly controlled despite taking multiple glucose-lowering therapies. Several studies have demonstrated that endogenous hypercortisolism is prevalent among these individuals. We tested whether cortisol-directed therapy improves their glycemic control. RESEARCH DESIGN AND METHODS In this prospective, multicenter, double-blind study, 136 individuals with T2D (hemoglobin A1c [HbA1c] 7.5%–11.5% [58–102 mmol/mol] on multiple medications) and hypercortisolism (by dexamethasone suppression test) were randomized 2:1 to the glucocorticoid receptor antagonist mifepristone (300–900 mg once daily; n = 91) or placebo (n = 45) for 24 weeks, with stratification by presence/absence of an adrenal imaging abnormality. The primary end point was the change in HbA1c. Secondary end points included changes in glucose-lowering medications, weight, and waist circumference and safety. RESULTS Mean baseline HbA1c in the study cohort was 8.55% (69.9 mmol/mol). At 24 weeks, the least squares mean (LSM) difference from placebo in HbA1c was −1.32% (95% CI −1.81 to −0.83; P &lt; 0.001). Participants receiving mifepristone experienced reductions in body weight and waist circumference (placebo-adjusted LSM differences of −5.12 kg [95% CI −8.20 to −2.03] and −5.1 cm [−8.23 to −1.99], respectively). Of participants on mifepristone, 46% discontinued therapy, compared with 18% on placebo. Adverse events with mifepristone (&gt;10% of participants) included hypokalemia, fatigue, nausea, vomiting, headache, peripheral edema, diarrhea, and dizziness, consistent with mifepristone’s known tolerability profile. Increases in blood pressure also occurred. CONCLUSIONS In individuals with inadequately controlled T2D and hypercortisolism, cortisol-directed medical therapy with mifepristone reduced HbA1c, with a manageable tolerability profile.

Purpose To establish international expert consensus on surgical techniques, complications, and rehabilitation protocols for lateral extra‐articular procedures (LEAPs) performed adjunctively with anterior cruciate ligament reconstruction. Methods Fifty‐five knee surgeons from 17 countries on 5 continents completed a 3‐round modified Delphi process. In the final round, 16 statements on LEAP techniques and complications were scored on a 5‐point Likert scale; ≥75% “agree/strongly agree” constituted consensus. When appropriate, strength of recommendation was graded. Statements lacking support were revised until consensus or abandonment. Results Six statements achieved unanimous consensus (100%), 2 had strong consensus (90%‐99.9%), and 3 reached consensus (75%‐89.9%); 4 were removed. Key technical recommendations were as follows: (1) in iliotibial band procedures, the graft strip should pass beneath the lateral collateral ligament; (2) an anatomic technique is mandatory for anterolateral ligament reconstruction; and (3) no single LEAP is clinically superior to another. Unanimous agreement indicated that modern LEAPs do not increase lateral compartment osteoarthritis risk, carry a low complication rate, and do not necessitate changes to rehabilitation or return‐to‐play timelines. Conclusions Consensus defined core surgical principles and confirmed the safety of adding LEAPs to anterior cruciate ligament reconstruction. When an iliotibial band graft is used, it should be routed deep to the lateral collateral ligament and fixed between 0° and 60° of knee flexion under low tension. For anterolateral ligament reconstruction, femoral fixation should be in full extension at a posterior‐proximal point relative to the lateral epicondyle. Although no single LEAP proved superiority, adherence to these principles permits safe, effective surgery without altering standard rehabilitation or return‐to‐sport protocols and without increasing osteoarthritis risk.

Purpose To define expert consensus on whether and how lateral extra‐articular procedures (LEAPs) should accompany anterior cruciate ligament (ACL) reconstruction to optimize outcomes in ACL‐deficient knees. Methods Fifty‐five knee surgeons from 17 countries on 5 continents completed a 3‐round modified Delphi process. Twenty‐one statements on patient selection for combined ACL reconstruction (ACLR) + LEAPs were graded on 5‐point Likert scales; ≥75% “agree/strongly agree” signified consensus. Strength of recommendation was ranked, and statements failing the threshold were revised or discarded after discussion. Results One statement achieved unanimous agreement (100%): it is strongly recommended to add a LEAP for active patients ≤25 years receiving hamstring‐autograft ACLR to reduce graft failure. Strong consensus (≥90%) supported LEAPs in primary ACLR when grade 3 pivot shift (97.9%), knee hyperextension (97.9%), skeletally immature status (79.5%), revision ACLR (91.5%), return to pivoting sports (93.2%), active patients ≤25 years using nonhamstring grafts (90.7%), grade 3 Lachman test (90%), and when multiple relative risk factors coexist (statement 36, 97.1%). Consensus (75%‐89.9%) favored LEAPs for chronic symptomatic ACL deficiency (86.1%), posterior tibial slope >12° (85.7%), and a history of contralateral ACL injury (88.9%). Eight statements did not reach consensus regarding small‐diameter autografts, female athletes, imaging signs of anterolateral injury (e.g., Segond fracture, lateral femoral‐notch sign), and concomitant meniscal procedures. One statement on LEAPs with primary ACL repair was withdrawn because the project focused on reconstruction. Conclusions International experts strongly recommend adding a LEAP in young active patients undergoing hamstring‐autograft ACLR and in cases of high‐grade rotational or anterior laxity, knee hyperextension, revision surgery, or returning to pivoting sports. Unresolved issues include small graft size, female athletes, imaging findings of rotational instability, and concurrent meniscal procedures, highlighting priorities for future research.

Abstract This review explores the pivotal role of preanalytical variables in bringing liquid biopsy approaches into the clinic for brain tumors. Preanalytical variables encompass a range of critical issues, from blood sample collection and handling to the impact of tumor heterogeneity and patient-specific factors. These variables introduce challenges such as false positives, false negatives, and variability in the analysis of tumor signals, which can hinder the diagnostic and prognostic utility of liquid biopsies. Understanding the nuances of preanalytical variables is essential for the successful implementation of liquid biopsy in clinical settings. This paper delves into strategies aimed at mitigating the influence of preanalytical variables by emphasizing the importance of standardized sample collection protocols, optimized sample processing and storage, quality control measures, and the integration of multiple liquid biopsy modalities.
