UNASSIGNED: Increased diagnostic awareness and specific disease treatments have changed the landscape of transthyretin cardiac amyloidosis (ATTR). Patients with wild-type ATTR (ATTRwt) are increasingly being diagnosed, potentially changing the clinical profile and prognosis compared with existing retrospective data. We aimed to study the clinical characteristics, distribution of red flags and prognosis of contemporary ATTRwt patients.
UNASSIGNED: From January 1st 2017, to December 31st 2022, 213 consecutive patients were diagnosed with ATTRwt and prospectively followed up. Data on clinical characteristics, biomarkers, echocardiography findings, hospitalization due to worsening heart failure (WHF) and all-cause mortality were collected.
UNASSIGNED: A 37% increase in newly diagnosed patients from 2017-2019 (n = 90) vs. 2020-2022 (n = 123) was observed. The majority of patients presented with NAC disease stage I in the latter period (49% in 2017-2019 vs. 58% in 2020-2022, p = .16). Red flags were primarily cardiac-related, including elevated NT-proBNP, impaired left ventricular longitudinal systolic strain with an apical sparing pattern, heart failure with increased left ventricular wall thickness and elevated troponins. NAC disease stage I as well as low NT-proBNP levels (<1000 ng/L) were significantly associated with better survival (both p < .001). When compared with NAC disease stage II + III combined, patients with NAC disease stage I had a significantly lower risk of WHF hospitalization or death (log rank test: p = .0001). Independent predictors of the combined endpoint WHF hospitalization or death were NT-proBNP (HR 1.03 [95% CI 1.00-1.07], p < .049) and prior implantation of permanent pacemaker (HR 2.01 [1.30-3.11], p = .002).
UNASSIGNED: Increased diagnostic awareness resulted in a 37% increase in newly diagnosed patients in 2020-2022 vs. 2017-2019. As expected all-cause mortality but also the morbidity in terms of risk of hospitalization with WHF were significantly lower in patients with NAC disease stage I, as well as in those with low NT-proBNP levels <1000 ng/L. These findings underline the importance of continuous attention to diagnostic awareness, as early diagnosis is critical for initiating both general and specific ATTR treatment, thus improving prognosis.

Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3-6 years. Because of the non-specificity of initial symptom manifestation and insufficient awareness among treating physicians, approximately one-third of patients with ATTRwt-CM are initially misdiagnosed with other cardiac diseases. Although heart failure (HF) is the most common initial manifestation of ATTRwt-CM, observed in nearly 70% of affected patients, patients may also present with other cardiologic symptoms, such as atrial fibrillation (AF) and aortic stenosis (AS). This non-specific and diverse nature of the initial ATTRwt-CM presentation indicates that various cardiology subspecialties are involved in patient diagnosis and management. Standard guideline-directed pharmacological treatment for HF is not recommended for patients with ATTRwt-CM because of its limited effectiveness. However, no established algorithms are available regarding HF management in this patient population. This literature review provides an overview of the red flags for ATTRwt-CM and research findings regarding HF management in this patient population. In addition to commonly recognized red flags for ATTRwt-CM (e.g., HF, AF and severe AS), published literature identified potential red flags such as coronary microvascular dysfunction. For HF management in patients with ATTRwt-CM, the use of mineralocorticoid receptor antagonists (MRAs) was reported as a well-tolerated option associated with a low discontinuation rate and reduced mortality. Although there is no concrete evidence for recommendations against sodium-glucose cotransporter 2 inhibitor (SGLT2i) administration, research supporting its use is limited to small-scale studies. Robust evidence is lacking for AF ablation, implantable cardioverter-defibrillators and cardiac resynchronization therapy. Based on the published findings and our clinical experience as Japanese ATTRwt-CM experts, red-flag symptom clusters for each cardiology specialty (HF, arrhythmia and ischaemia/structural heart disease) and a treatment scheme for HF management are presented. As this research area remains at an exploratory stage, our observations would require further discussion among experts worldwide.

BACKGROUND: Low back pain (LBP) is a prevalent healthcare concern that is frequently responsive to conservative treatment. However, it can also stem from severe conditions, marked by \'red flags\' (RF) such as malignancy, cauda equina syndrome, fractures, infections, spondyloarthropathies, and aneurysm rupture, which physicians should be vigilant about. Given the increasing reliance on online health information, this study assessed ChatGPT-3.5\'s (OpenAI, San Francisco, CA, USA) and GoogleBard\'s (Google, Mountain View, CA, USA) accuracy in responding to RF-related LBP questions and their capacity to discriminate the severity of the condition.
METHODS: We created 70 questions on RF-related symptoms and diseases following the LBP guidelines. Among them, 58 had a single symptom (SS), and 12 had multiple symptoms (MS) of LBP. Questions were posed to ChatGPT and GoogleBard, and responses were assessed by two authors for accuracy, completeness, and relevance (ACR) using a 5-point rubric criteria.
RESULTS: Cohen\'s kappa values (0.60-0.81) indicated significant agreement among the authors. The average scores for responses ranged from 3.47 to 3.85 for ChatGPT-3.5 and from 3.36 to 3.76 for GoogleBard for 58 SS questions, and from 4.04 to 4.29 for ChatGPT-3.5 and from 3.50 to 3.71 for GoogleBard for 12 MS questions. The ratings for these responses ranged from \'good\' to \'excellent\'. Most SS responses effectively conveyed the severity of the situation (93.1% for ChatGPT-3.5, 94.8% for GoogleBard), and all MS responses did so. No statistically significant differences were found between ChatGPT-3.5 and GoogleBard scores (p>0.05).
CONCLUSIONS: In an era characterized by widespread online health information seeking, artificial intelligence (AI) systems play a vital role in delivering precise medical information. These technologies may hold promise in the field of health information if they continue to improve.

Acute compartment syndrome (ACS) is defined by a disorder of the microcirculation due to a persistent pathological pressure increase within a muscle compartment. The ischemia of the tissue leads to an initially reversible functional impairment and finally irreversible damage of the musculature, nerves and other structures. Based on the understanding of the pathophysiology, the current diagnostic concepts and treatment using the so-called dermatofasciotomy of the affected muscle compartments can be derived. In addition to the suspicion of a possible ACS based on the medical history of the patient, the findings of the clinical examination are decisive. This review article gives a summary of all the essential aspects of the diagnostics. In clinically uncertain cases and for monitoring, an objectification of the findings using instrument-based techniques is increasingly required. Nowadays, invasive needle pressure measurement is available; however, due to limited reliability, specificity and sensitivity, these measurements only represent an aid to decision guidance supporting or advising against the indications for dermatofasciotomy. The increasing demands on making a certain diagnosis and justification of a surgical intervention from a legal point of view, substantiate the numerous scientific efforts to develop noninvasive instrument-based diagnostics. These methods are based either on detection of increasing intracompartmental pressure or decreasing perfusion pressure and microcirculation. The various measurement principles are summarized in a lucid form.
UNASSIGNED: Das akute Kompartmentsyndrom (ACS) ist definiert durch eine Mikrozirkulationsstörung bei andauernder, pathologischer Druckerhöhung innerhalb einer Muskelloge. Durch die Ischämie des Gewebes kommt es zu einer anfangs reversiblen Funktionseinschränkung und schließlich zur irreversiblen Schädigung der Muskulatur, Nerven und weiterer Strukturen. Durch das Verständnis für die Pathophysiologie lassen sich die aktuellen diagnostischen Konzepte und die Therapie mithilfe der sog. Dermatofasziotomie der betroffenen Muskellogen ableiten. Neben einem Verdacht auf ein mögliches ACS aufgrund der positiven Anamnese ist der klinische Untersuchungsbefund entscheidend. Dieser Übersichtsartikel fasst alle wesentlichen Aspekte der Diagnostik zusammen. In klinisch nicht eindeutigen Fällen und zum Monitoring wird eine Objektivierung des Befundes durch apparative Techniken zunehmend gefordert. Heute steht uns die invasive Nadeldruckmessung zur Verfügung, die jedoch aufgrund einer limitierten Reliabilität, Sensitivität und Spezifität lediglich eine Entscheidungshilfe für oder gegen die Indikation zur Kompartmentspaltung darstellt. Der zunehmende Anspruch der sicheren Diagnosestellung und Rechtfertigung einer chirurgischen Intervention aus juristischer Sicht begründet die vielzähligen wissenschaftlichen Anstrengungen, eine nichtinvasive, apparative Diagnostik zu entwickeln. Die Methoden basieren entweder auf der Messung eines steigenden Logendrucks oder eines sinkenden Perfusionsdrucks und Mikrozirkulation. Die unterschiedlichen Messprinzipien werden in übersichtlicher Form zusammengefasst.

Although a rare spinal emergency, cauda equina syndrome (CES) can result in significant physical, emotional, and psychological sequalae. Introducing a CES pathway enhances diagnosis but may increase Radiology and Orthopaedic workload. To address this, one NHS hospital in England introduced a novel CES pathway. Utilising a criteria-led pathway, patients were referred directly from community/primary care, via the Emergency Department, for an emergency MRI scan.
To compare the outcomes of patients referred via an original and redesigned Community and Primary Care CES pathway.
A retrospective service evaluation was undertaken of all emergency MRI scans investigating suspected CES via either pathway.
Two 3-month time periods were analysed; pre-(original) and post-implementation of the redesigned pathway; time to surgery was reviewed over two 12-month periods.
Increased MRI scan utilisation was seen following the implementation of the redesigned pathway: original n = 50, redesigned n = 128, increasing Radiology workload. However, the redesigned pathway resulted in a reduction in time to MRI from 3h:01m to 1h:02m; reduction in time spent in ED 4h:55m to 3h:24m; reduction in time to surgery 18h:05m to 13h:38m; reduction in out-of-hour scanning from 10 to 2 patients during the evaluation period; and a reduction in on-call Orthopaedic involvement by 38%.
All timed outcomes were improved with the implementation of this novel pathway. This suggests expediting MRI scans can result in substantial downstream benefits; albeit while increasing MRI scan utilisation. This pathway aligns with the emergency management of suspected CES under the new national CES pathway in England.

UNASSIGNED: Physiotherapists must identify potential red flags that may impede recovery and function in individuals with low back pain (LBP) or put them at risk.
UNASSIGNED: This study aimed to (1) investigate physiotherapists\' awareness and use of red flags for individuals with LBP in Saudi Arabia and (2) identify factors associated with their awareness and use of LBP red flags.
UNASSIGNED: This cross-sectional study collected data using an anonymous online questionnaire (February-July 2023). It included physiotherapists working in private/public hospitals in Saudi Arabia. The questionnaire asked about the participants\' characteristics, their awareness of LBP red flags, and their use of red flags for LBP assessment.
UNASSIGNED: A total of 643 participating physiotherapists (26.2 ± 3.8 years), 63.8% of whom were females, completed the survey. Most participants (94.4%) had adequate awareness of LBP red flags, and more than half (61%) had good utilization of red flags when assessing individuals with LBP. There was a positive correlation between the physiotherapists\' awareness and use of LBP red flags.
UNASSIGNED: The majority of the participating physiotherapists in Saudi Arabia were aware of LBP red flags, and many reported to have good use of red flags in clinical practice when assessing and managing individuals with LBP.

Febrile seizures (FS) are commonly perceived by healthcare professionals as a self-limited condition with a generally \'benign\' nature. Nonetheless, they frequently lead to pediatric consultations, and their management can vary depending on the clinical context. For parents and caregivers, witnessing a seizure can be a distressing experience, significantly impacting their quality of life. In this review, we offer an in-depth exploration of FS management, therapeutic interventions, and prognostic factors, with the aim of providing support for physicians and enhancing communication with families. We conducted a comprehensive literature search using the PubMed and Web of Science databases, spanning the past 50 years. The search terms utilized included \"febrile seizure,\" \"complex febrile seizure,\" \"simple febrile seizure,\" in conjunction with \"children\" or \"infant.\" Only studies published in English or those presenting evidence-based data were included in our assessment. Additionally, we conducted a cross-reference search to identify any additional relevant data sources. Our thorough literature search resulted in a compilation of references, with carefully selected papers thoughtfully integrated into this review.

BACKGROUND: The \'diagnostic odyssey\' is a common challenge faced by patients living with rare diseases and poses a significant burden for patients, their families and carers, and the healthcare system. The diagnosis of rare diseases in clinical settings is challenging, with patients typically experiencing a multitude of unnecessary tests and procedures. To improve diagnosis of rare disease, clinicians require evidence-based guidance on when their patient may be presenting with a rare disease. This study aims to identify common experiences amongst patients with rare diseases, to inform a series of \'red flags\' that can aid diagnosis of rare diseases in non-specialist settings. A questionnaire was developed by Medics for Rare Diseases, informed by the experiences of clinicians, rare disease patients and patient advocates, and was shared with UK-based rare disease patient groups. Study participants were engaged via social media platforms, blogs and email newsletters of three umbrella rare disease organisations. The questionnaire, comprising 22 questions, was designed to identify typical experiences relating to physical and psychosocial manifestations and presentation of disease, patient interactions with healthcare providers, and family history.
RESULTS: Questionnaire responses were received from 79 different rare disease patient groups and the common experiences identified were used to inform seven red flags of rare disease: multi-system involvement (3 or more); genetic inheritance pattern; continued presentation throughout childhood and adulthood; difficulties at school, especially relating to absences, difficulty participating in physical education and experiences of bullying or social isolation; multiple specialist referrals; extended period with unexplained symptoms; and misdiagnosis. In light of the red flags identified, recommendations for primary care and education settings have been proposed, focusing on the need for holistic assessment and awareness of both physical and psychosocial factors.
CONCLUSIONS: This study identified key commonalities experienced by patients with rare disease across physical and psychosocial domains, in addition to understanding patients\' history and experiences with healthcare providers. These findings could be used to develop a clinical decision‑making tool to support non-specialist practitioners to consider when their patient may have an undiagnosed rare condition, which may minimise the challenges of the \'diagnostic odyssey\' and improve the patient experience.

In recent years, the interest in cardiac amyloidosis has grown exponentially. However, there is a need to improve our understanding of amyloidosis in order to optimise early detection systems. Therefore, it is crucial to incorporate solutions to improve the suspicion, diagnosis and follow-up of cardiac amyloidosis. In this sense, we designed a tool following the different phases to reach the diagnosis of cardiac amyloidosis, as well as an optimal follow-up: a) clinical suspicion, where the importance of the \"red flags\" to suspect it and activate the diagnostic process is highlighted; 2) diagnosis, where the diagnostic algorithm is mainly outlined; and 3) follow-up of confirmed patients. This is a practical resource that will be of great use to all professionals caring for patients with suspected or confirmed cardiac amyloidosis, to improve its early detection, as well as to optimise its accurate diagnosis and optimal follow-up.

The prevalence of transthyretin amyloid cardiomyopathy (ATTR-CM) in atrial fibrillation (AF) patients remains unclear. We explored the efficacy of computed tomography-based myocardial extracellular volume (CT-ECV) combined with red flags for the early screening of concealed ATTR-CM in AF patients undergoing catheter ablation.
Patients referred for AF ablation at Oita University Hospital were prescreened using the red-flag signs defined by echocardiographic or electrocardiographic findings, medical history, symptoms, and blood biochemical findings. Myocardial CT-ECV was quantified in red flag-positive patients using routine pre-AF ablation planning cardiac CT with the addition of delayed-phase cardiac CT scans. Patients with high (>35%) ECV were evaluated using technetium pyrophosphate (99 mTc-PYP) scintigraphy. A cardiac biopsy was performed during the planned AF ablation procedure if 99 mTc-PYP scintigraphy was positive. Between June 2022 and June 2023, 342 patients were referred for AF ablation. Sixty-seven (19.6%) patients had at least one of the red-flag signs. Myocardial CT-ECV was evaluated in 57 patients because of contraindications to contrast media, revealing that 16 patients had high CT-ECV. Of these, 6 patients showed a positive 99 mTc-PYP study, and 6 patients were subsequently diagnosed with wild-type ATTR-CM via cardiac biopsy and genetic testing.
CT-ECV combined with red flags could contribute to the systematic early screening of concealed ATTR-CM in AF patients undergoing catheter ablation.
