RESUMO

In a first-of-its-kind study, we assessed the capabilities of large language models (LLMs) in making complex decisions in haematopoietic stem cell transplantation. The evaluation was conducted not only for Generative Pre-trained Transformer 4 (GPT-4) but also conducted on other artificial intelligence models: PaLm 2 and Llama-2. Using detailed haematological histories that include both clinical, molecular and donor data, we conducted a triple-blind survey to compare LLMs to haematology residents. We found that residents significantly outperformed LLMs (p = 0.02), particularly in transplant eligibility assessment (p = 0.01). Our triple-blind methodology aimed to mitigate potential biases in evaluating LLMs and revealed both their promise and limitations in deciphering complex haematological clinical scenarios.

RESUMO

The European Trauma Course (ETC) exemplifies an innovative approach to multispecialty trauma education. This initiative was started as a collaborative effort among the European Society for Emergency Medicine, the European Society for Trauma and Emergency Surgery, and the European Society of Anaesthesiology under the auspices of the European Resuscitation Council. With the robust support of these societies, the project has evolved into the independent European Trauma Course Organisation. Over the past 15 years, the ETC has transcended traditional training by integrating team dynamics and non-technical skills into a scenario-based simulation course, helping to shape trauma care practice and education. A distinctive feature of the ETC is its training of doctors and allied healthcare professionals, fostering a collaborative and holistic approach to trauma care. The ETC stands out for its unique team-teaching approach, which has gained widespread recognition as the standard for in-hospital trauma care training not only in Europe but also beyond. Since its inception ETC has expanded geographically from Finland to Sudan and from Brazil to the Emirates, training nearly 20,000 healthcare professionals and shaping trauma care practice and education across 25 countries. Experiencing exponential growth, the ETC continues to evolve, reflecting its unmet demand in trauma team education. This review examines the evolution of the ETC, its innovative team-teaching methodology, national implementation strategies, current status, and future challenges. It highlights its impact on trauma care, team training, and the effect on other life support courses in various countries.

RESUMO

We report a case of dyspnea in a 71-year-old man who underwent heterotopic heart transplantation in 2003. At presentation, electrocardiography showed ventricular fibrillation of the native heart and then a progression to both donor and recipient hearts. Synchronized electrical cardioversion restored sinus rhythm and relieved the patient from his symptoms.

RESUMO

Acute myeloid leukemia (AML) identifies a heterogeneous group of clonal disorders, both clinically and genetically. A large number of mutations have been described in AML, although only a few are currently employed in clinical practice. Next generation sequencing (NGS) allows for better understanding of the complex genetic background in AML and may direct individualized therapies. In this study, we aim to identify molecular aberrations that are not routinely investigated in AML using an NGS-based panel encompassing 101 genes and to evaluate how their oncogenic potential correlates with survival. Forty consecutive patients with newly diagnosed AML were enrolled between January 2018 and April 2020. We performed targeted NGS and detected 96 mutations in 36 patients (90%), while 14 fusion genes were detected in 13 patients (32%). Each mutation was weighed using OncoScore, a text-mining tool ranking genes according to their oncogenic potential. An OncoScore ≥ 100 was associated with shorter PFS among our patients (p = 0.05). In 11 patients with no available MRD markers at diagnosis, we were able to perform NGS-based MRD monitoring using targeted deep sequencing. Overall, our study shows that NGS is a powerful tool in AML and should be employed both in routine diagnostic workup and follow up.

RESUMO

Clinical experience with hydroxocobalamin in acute cyanide poisoning via ingestion remains limited. This case concerns a 35-year-old mentally ill woman who consumed more than 20 apricot kernels. Published literature suggests each kernel would have contained cyanide concentrations ranging from 0.122 to 4.09 mg/g (average 2.92 mg/g). On arrival, the woman appeared asymptomatic with a raised pulse rate and slight metabolic acidosis. Forty minutes after admission (approximately 70 min postingestion), the patient experienced headache, nausea and dyspnoea, and was hypotensive, hypoxic and tachypnoeic. Following treatment with amyl nitrite and sodium thiosulphate, her methaemoglobin level was 10%. This prompted the administration of oxygen, which evoked a slight improvement in her vital signs. Hydroxocobalamin was then administered. After 24 h, she was completely asymptomatic with normalised blood pressure and other haemodynamic parameters. This case reinforces the safety and effectiveness of hydroxocobalamin in acute cyanide poisoning by ingestion.

RESUMO

Clofarabine (CLO) and cyclophosphamide (CY) combinations were tested in late stage refractory/relapsed (R/R) acute lymphoblastic leukemia (ALL) with disappointing results and high-grade toxicity. We designed a sequential 5-day combination of CLO 40 mg/m2/d plus CY 400 mg/m2/d as first salvage for Philadelphia-negative ALL patients refractory or relapsed until 24 months from complete remission (CR). Primary endpoint was an overall response rate (ORR) ≥ 40%. Among 26 study patients (median age 40.5 years) ORR was 57.6% (CR with complete [n = 8] or incomplete [n = 7] hematologic recovery). Despite severe myelotoxicity, no dose-limiting toxicity suggested de-intensification of CLO schedule. With a median follow-up of 17.0 months, median and 1-year overall and disease-free survival were 6.5 months and 28.6%, and 3.7 months and 28.1%, respectively. This association was tolerable and more effective in patients younger than 40 years with B-precursor ALL, longer first CR, not previously transplanted and achieving CR with full hematological recovery.

RESUMO

OBJECTIVE: To determine the accuracy of a new oscillometric home blood pressure (BP) monitor for arm BP measurement, the SAA-102, developed by the Sensacare Company. DESIGN: Evaluation of the SAA-102 was performed using validation protocols of the European Society of Hypertension (ESH), the Association for the Advancement of Medical Instrumentation (AAMI), and the British Hypertension Society (BHS). METHODS: The SAA-102 monitor was assessed on 33 participants according to ESH requirements, which are based on four zones of accuracy differing from the mercury standard by 5, 10, 15 mmHg or more. Then the oscillometric monitor was tested on 85 participants according to AAMI criteria which require a mean device-observers discrepancy within 5+/-8 mmHg. Finally, the electronic device was evaluated on 93 participants according to BHS requirements, which are based on five phases: before-use calibration, in-use assessment, after-use calibration, static device validation and report of the results. RESULTS: The SAA-102 passed all phases of the ESH international protocol for both systolic and diastolic blood pressure (SBP and DBP). The SAA-102 passed also AAMI criteria for SBP and DBP. The mean discrepancy between the SAA-102 and observers was 0.1+/-4.6 and -2.7+/-5.2 mmHg, for SBP and DBP, respectively. According to BHS protocol, the oscillometric monitor achieved final grading of A/A for SBP and DBP, respectively. CONCLUSION: These data show that the SAA-102 device satisfies ESH, AAMI, and BHS protocols for both SBP and DBP and may be recommended for everyday use for BP monitoring at home and in clinical practice.

RESUMO

BACKGROUND: Imatinib can induce severe hepatotoxicity, in 1-5% of CML patients, many of whom need permanent imatinib discontinuation. DESIGN AND RESULTS: We report 5 CML patients who developed grade 3-4 hepatotoxicity after 2-8 months in imatinib. Different aetiologies of liver damage were ruled out and toxicity recurred in 2 patients with further attempts at low dose imatinib. In all patients prednisone or methylprednisolone at 25- 40 mg/day resolved hepatotoxicity in 3-8 weeks and allowed imatinib to be resumed at full doses. Corticosteroid were tapered off in 3-5 months without hepatotoxicity recurrence. CONCLUSIONS: Corticosteroid may avoid discontinuation for hepatotoxicity of the most effective anti-CML therapy.

RESUMO

BACKGROUND: Slow, controlled breathing has been shown by cross-spectral techniques to potentiate arterial baroreflex control of heart rate. However, crucial aspects of the effects of slow breathing on the arterial baroreflex remain unsettled, namely whether the major function of the arterial baroreflex (i.e. the control of blood pressure) is also potentiated and whether baroreflex function is differentially modulated according to the age of the individual. OBJECTIVE: To examine the bradycardic and depressor responses to selective carotid baroreceptor stimulation by the neck chamber technique (-15 and -30 mmHg neck suction) and the cross-spectral R-R interval/systolic blood pressure relationship (alpha index). METHODS: In 24 resting, supine healthy male volunteers (aged 19-66 years, mean +/-SEM 37.5 +/- 3.19 years), blood pressure (Finapres), R-R interval (electrocardiogram) and ventilation (impedance) were recorded continuously. Both assessments were performed during spontaneous breathing and during 6 cycles/min controlled ventilation in random order. RESULTS: The depressor and bradycardic responses to neck suction were significantly larger during slow breathing than in spontaneous breathing (+32 and +85%, respectively; both P < 0.01). The alpha index was also significantly larger during slow breathing (+62%; P < 0.01). Even after the volunteers were divided into older (> 50 years, n = 9) and younger (< 30 years, n = 9) groups, the baroreflex potentiation related to slow breathing was clearcut and significant for both the depressor (+46 and +24% older and younger volunteers; both P < 0.01) and the bradycardic (+130 and +73% older and younger volunteers; both P < 0.01) responses. When the assessment was made by computing the cross-spectral alpha index, a marked potentiation related to slow breathing was observed in younger volunteers (+99%; P < 0.01), whereas in older volunteers only a trend to an enhancement (by 32%; P < 0.055) was observed. CONCLUSIONS: Slow controlled breathing is associated with potentiation of both the depressor and the cardio-inhibitory components of the arterial baroreflex, the potentiation being largely similar regardless of the age of the individual.

RESUMO

OBJECTIVE: To determine the accuracy of the SAW-102 wrist oscillometric blood pressure monitor developed by the Sensacare Company according to the protocols of the European Society of Hypertension (ESH), the Association for the Advancement of Medical Instrumentation (AAMI), and the British Hypertension Society (BHS). METHODS: SAW-102 was assessed on 33 participants according to ESH requirements, based on four zones of accuracy differing from the mercury standard by 5, 10, 15 mmHg or more. Then SAW-102 was tested on 85 participants according to AAMI criteria requiring mean device-observers discrepancy within 5+/-8 mmHg. Subsequently, SAW-102 was evaluated on 88 participants according to BHS requirements. Finally, 15 participants with wrist circumference greater than the manufacturer's recommendation (19.5 cm) were studied (large wrist group). Efforts were made to secure a stable position of wrist and arm at the heart level. RESULTS: SAW-102 passed all phases of ESH international protocol for both systolic blood pressure (SBP) and diastolic blood pressure (DBP). SAW-102 passed AAMI criteria with mean differences between SAW-102 and observers of 3.8+/-7.5 and 1.5+/-6.0 mmHg, SBP and DPB, respectively. According to BHS protocol, the device achieved final grading of B/B for SBP and DBP, respectively. Large wrist group did not pass the first phase of ESH protocol. CONCLUSION: This study demonstrated that SAW-102 meets the BHS, ESH, and AAMI standards when measurements are done at the heart level and when the manufacturer's specifications, regarding wrist circumference, are respected. Our data also indicate that exceeding 19.5 cm wrist circumference is accompanied by dramatic decrease of the accuracy of the device.
