Assessing ChatGPT's theoretical knowledge and prescriptive accuracy in bacterial infections: a comparative study with infectious diseases residents and specialists.

OBJECTIVES: Advancements in Artificial Intelligence(AI) have made platforms like ChatGPT increasingly relevant in medicine. This study assesses ChatGPT's utility in addressing bacterial infection-related questions and antibiogram-based clinical cases. METHODS: This study involved a collaborative effort involving infectious disease (ID) specialists and residents. A group of experts formulated six true/false, six open-ended questions, and six clinical cases with antibiograms for four types of infections (endocarditis, pneumonia, intra-abdominal infections, and bloodstream infection) for a total of 96 questions. The questions were submitted to four senior residents and four specialists in ID and inputted into ChatGPT-4 and a trained version of ChatGPT-4. A total of 720 responses were obtained and reviewed by a blinded panel of experts in antibiotic treatments. They evaluated the responses for accuracy and completeness, the ability to identify correct resistance mechanisms from antibiograms, and the appropriateness of antibiotics prescriptions. RESULTS: No significant difference was noted among the four groups for true/false questions, with approximately 70% correct answers. The trained ChatGPT-4 and ChatGPT-4 offered more accurate and complete answers to the open-ended questions than both the residents and specialists. Regarding the clinical case, we observed a lower accuracy from ChatGPT-4 to recognize the correct resistance mechanism. ChatGPT-4 tended not to prescribe newer antibiotics like cefiderocol or imipenem/cilastatin/relebactam, favoring less recommended options like colistin. Both trained- ChatGPT-4 and ChatGPT-4 recommended longer than necessary treatment periods (p-value = 0.022). CONCLUSIONS: This study highlights ChatGPT's capabilities and limitations in medical decision-making, specifically regarding bacterial infections and antibiogram analysis. While ChatGPT demonstrated proficiency in answering theoretical questions, it did not consistently align with expert decisions in clinical case management. Despite these limitations, the potential of ChatGPT as a supportive tool in ID education and preliminary analysis is evident. However, it should not replace expert consultation, especially in complex clinical decision-making.

Use of Cefiderocol in Adult Patients: Descriptive Analysis from a Prospective, Multicenter, Cohort Study.

INTRODUCTION: Cefiderocol is a siderophore cephalosporin showing activity against various carbapenem-resistant Gram-negative bacteria (CR-GNB). No data currently exist about real-world use of cefiderocol in terms of types of therapy (e.g., empirical or targeted, monotherapy or combined regimens), indications, and patient characteristics. METHODS: In this multicenter, prospective study, we aimed at describing the use of cefiderocol in terms of types of therapy, indications, and patient characteristics. RESULTS: Cefiderocol was administered as empirical and targeted therapy in 27.5% (55/200) and 72.5% (145/200) of cases, respectively. Overall, it was administered as monotherapy in 101/200 cases (50.5%) and as part of a combined regimen for CR-GNB infections in the remaining 99/200 cases (49.5%). In multivariable analysis, previous isolation of carbapenem-resistant Acinetobacter baumannii odds ratio (OR) 2.56, with 95% confidence interval (95% CI) 1.01-6.46, p = 0.047] and previous hematopoietic stem cell transplantation (OR 8.73, 95% CI 1.05-72.54, p = 0.045) were associated with administration of cefiderocol as part of a combined regimen, whereas chronic kidney disease was associated with cefiderocol monotherapy (OR 0.38 for combined regimen, 95% CI 0.16-0.91, p = 0.029). Cumulative 30-day mortality was 19.8%, 45.0%, 20.7%, and 22.7% in patients receiving targeted cefiderocol for infections by Enterobacterales, A. baumannii, Pseudomonas aeruginosa, and any metallo-ß-lactamase producers, respectively. CONCLUSIONS: Cefiderocol is mainly used for targeted treatment, although empirical therapies account for more than 25% of prescriptions, thus requiring dedicated standardization and guidance. The almost equal distribution of cefiderocol monotherapy and cefiderocol-based combination therapies underlines the need for further study to ascertain possible differences in efficacy between the two approaches.

[Recommendations for the management of latex allergy in pediatrics]. / Recomendaciones para el manejo de la alergia al látex en pediatría.

Latex allergy, or natural rubber latex allergy (NRLA), is a global health concern, even among the pediatric population, with symptoms varying in severity from mild to potentially life-threatening. Latex is derived from the Hevea Brasiliensis tree, producing twelve million tons annually for use in various everyday and medical products. Despite efforts to mitigate NRLA, its prevalence remains high, especially in at- risk groups such as children with spina bifida. Clinical manifestations include immediate and delayed symptoms, even anaphylactic reactions. Diagnosis involves a detailed medical history and specific tests. Prevention focuses on avoiding exposure, especially in medical and educational settings. Treatment, including immunotherapy, exhibits variable efficacy. NRLA has a strong negative impact on children's quality of life. The objective of this publication is to provide updated information and practical tools for the pediatrician's and allergist's practice.

La alergia al látex del caucho natural (ALCN) es un problema de salud global, incluso en población pediátrica, con síntomas de gravedad variable, desde leves hasta potencialmente mortales. El látex se obtiene del árbol Hevea brasiliensis; se producen doce millones de toneladas anuales que se utilizan en diversos productos cotidianos y médicos. A pesar de los esfuerzos para mitigar la ALCN, su prevalencia sigue siendo alta, especialmente en grupos de riesgo, como niños con espina bífida. Las manifestaciones clínicas incluyen síntomas inmediatos y retardados, hasta reacciones anafilácticas. El diagnóstico requiere una historia clínica detallada y pruebas específicas. La prevención se centra en evitar la exposición, especialmente en entornos médicos y escolares. El tratamiento, incluida la inmunoterapia, muestra eficacia variable. La ALCN tiene un fuerte impacto negativo en la calidad de vida. El objetivo de esta publicación es proveer información actualizada y herramientas prácticas para el consultorio del pediatra y el alergólogo.

Unveiling the Secrets of Acinetobacter baumannii: Resistance, Current Treatments, and Future Innovations.

Acinetobacter baumannii represents a significant concern in nosocomial settings, particularly in critically ill patients who are forced to remain in hospital for extended periods. The challenge of managing and preventing this organism is further compounded by its increasing ability to develop resistance due to its extraordinary genomic plasticity, particularly in response to adverse environmental conditions. Its recognition as a significant public health risk has provided a significant impetus for the identification of new therapeutic approaches and infection control strategies. Indeed, currently used antimicrobial agents are gradually losing their efficacy, neutralized by newer and newer mechanisms of bacterial resistance, especially to carbapenem antibiotics. A deep understanding of the underlying molecular mechanisms is urgently needed to shed light on the properties that allow A. baumannii enormous resilience against standard therapies. Among the most promising alternatives under investigation are the combination sulbactam/durlobactam, cefepime/zidebactam, imipenem/funobactam, xeruborbactam, and the newest molecules such as novel polymyxins or zosurabalpin. Furthermore, the potential of phage therapy, as well as deep learning and artificial intelligence, offer a complementary approach that could be particularly useful in cases where traditional strategies fail. The fight against A. baumannii is not confined to the microcosm of microbiological research or hospital wards; instead, it is a broader public health dilemma that demands a coordinated, global response.

SARS-CoV-2 associated unilateral parotitis in children: A case report and literature review.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection usually affects the respiratory system; however, a number of atypical manifestations of this disease have also been reported, especially in children. The present study reports a case of a 12-year-old presenting with right unilateral parotitis and sialadenitis and SARS-CoV-2 infection. The young patient, after a 3-day history of fever, was brought to our clinic (Polyclinic University Hospital 'G. Rodolico', Catania, Italy) for the sudden onset of unilateral parotitis accompanied by sialadenitis and hyperaemia of the skin, which was tender to touch. The SARS-CoV-2 molecular swab was positive; the ultrasound of the affected region showed an increase in the volume of the parotid and sublingual gland and reactive lymph nodes compatible with parotitis and sialadenitis. This case suggests that, in the present Coronavirus disease 2019 pandemic, SARS-CoV-2 should be included in the differential diagnosis of parotitis and sialadenitis along with mumps and flue. Notably, a respiratory panel and serology for other potential causes are needed in case of parotitis-like disease.

Navigating the Nexus: HIV and Breast Cancer-A Critical Review.

Despite significant advances in the management of antiretroviral therapy (ART), leading to improved life expectancy for people living with HIV (PLWH), the incidence of non-AIDS-defining cancers, including breast cancer, has emerged as a critical concern. This review synthesizes current evidence on the epidemiology of breast cancer among HIV-infected individuals, highlighting the potential for an altered risk profile, earlier onset, and more advanced disease at diagnosis. It delves into the molecular considerations underpinning the relationship between HIV and breast cancer, including the role of immunosuppression, chronic inflammation, and gene expression alterations. Additionally, it examines the complexities of managing breast cancer in the context of HIV, particularly the challenges posed by ART and anticancer agents' cross-toxicities and drug-drug interactions. The review also addresses survival disparities, underscoring the need for improved cancer care in this population. By identifying gaps in knowledge and areas requiring further research, this review aims to illuminate the complexities of HIV-associated breast cancer, fostering a deeper understanding of its epidemiology, molecular basis, and clinical management challenges, thereby contributing to better outcomes for individuals at the intersection of these two conditions. This narrative review systematically explores the intersection of HIV infection and breast cancer, focusing on the impact of HIV on breast cancer risk, outcomes, and treatment challenges.

Spectroscopic Evidence of Kondo-Induced Quasiquartet in CeRh_{2}As_{2}.

CeRh_{2}As_{2} is a new multiphase superconductor with strong suggestions for an additional itinerant multipolar ordered phase. The modeling of the low-temperature properties of this heavy-fermion compound requires a quartet Ce^{3+} crystal-field ground state. Here, we provide the evidence for the formation of such a quartet state using x-ray spectroscopy. Core-level photoelectron and x-ray absorption spectroscopy confirm the presence of Kondo hybridization in CeRh_{2}As_{2}. The temperature dependence of the linear dichroism unambiguously reveals the impact of Kondo physics for coupling the Kramer's doublets into an effective quasiquartet. Nonresonant inelastic x-ray scattering data find that the |Γ_{7}^{-}⟩ state with its lobes along the 110 direction of the tetragonal structure (xy orientation) contributes most to the multiorbital ground state of CeRh_{2}As_{2}.

Understanding clinical outcomes and factors influencing mortality in intensive care unit patients with COVID-19-associated candidemia.

BACKGROUND: During the COVID pandemic, research has shown an increase in candidemia cases following severe COVID infection and the identification of risk factors associated with candidemia. However, there is a lack of studies that specifically explore clinical outcomes and mortality rates related to candidemia after COVID infection. OBJECTIVES: The aim of this international study was to evaluate the clinical outcomes and identify factors influencing mortality in patients who developed candidemia during their COVID infection. PATIENTS/METHODS: This study included adult patients (18 years of age or older) admitted to the intensive care unit (ICU) and diagnosed with COVID-associated candidemia (CAC). The research was conducted through ID-IRI network and in collaboration with 34 medical centres across 18 countries retrospectively, spanning from the beginning of the COVID pandemic until December 2021. RESULTS: A total of 293 patients diagnosed with CAC were included. The median age of the patients was 67, and 63% of them were male. The most common Candida species detected was C. albicans. The crude 30-day mortality rate was recorded at 62.4%. The logistic regression analysis identified several factors significantly impacting mortality, including age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.07, p < .0005), SOFA score (OR 1.307, 95% CI 1.17-1.45, p < .0005), invasive mechanical ventilation (OR 7.95, 95% CI 1.44-43.83, p < .017) and duration of mechanical ventilation (OR 0.98, 95% CI 0.96-0.99, p < .020). CONCLUSIONS: By recognising these prognostic factors, medical professionals can customise their treatment approaches to offer more targeted care, leading to improved patient outcomes and higher survival rates for individuals with COVID-associated candidemia.

Rinitis alérgica en pediatría: recomendaciones para su diagnóstico y tratamiento / Allergic rhinitis in pediatrics: recommendations for diagnosis and treatment

La rinitis alérgica (RA) es una de las enfermedades crónicas más frecuentes de la infancia. Sin embargo, permanece subdiagnosticada y subtratada. Su prevalencia ha aumentado en los últimos años y varía del 2 % al 25 %. Los síntomas de la RA incluyen estornudos, prurito, rinorrea y congestión nasal. Un correcto diagnóstico y tratamiento de la RA y sus comorbilidades, tales como rinosinusitis con o sin poliposis nasal, conjuntivitis, otitis media, asma bronquial e infecciones del tracto respiratorio, son importantes para reducir el impacto negativo en la afectación de la calidad de vida del paciente y sus familiares, y los gastos sanitarios que ocasiona. La inmunoterapia alérgeno específica, en pacientes correctamente seleccionados, previene nuevas sensibilizaciones y reduce la hiperreactividad bronquial asociada a la RA. Considerando todos estos factores, el Comité Nacional de Alergia de la Sociedad Argentina de Pediatría propone recomendaciones basadas en la evidencia actual.

Allergic rhinitis (AR) is one of the most common chronic diseases in children. However, it remains underdiagnosed and undertreated. Its prevalence has increased in recent years and varies from 2 to 25 %. Symptoms include sneezing, itching, runny nose, and nasal congestion. A correct diagnosis and treatment of AR and its comorbidities such as rhinosinusitis with or without nasal polyposis, conjunctivitis, otitis media, bronchial asthma and respiratory tract infections, are important to reduce the negative impact on the quality of life of the patient and their relatives, and in medical costs. Specific allergen immunotherapy, in correctly selected patients, prevents new sensitizations and reduces bronchial hyperreactivity associated with AR. Taking into account all these reasons, the National Allergy Committee of the Sociedad Argentina de Pediatría proposes current evidence based recommendations

Urea/Creatinine Ratio's Correlation with Creatine Kinase Normalization in Pediatric COVID-19 Patients with Myositis: Evaluating Prognostic and Predictive Value.

Coronavirus disease 2019 (COVID-19) has been chiefly linked with substantial respiratory complications. However, emerging studies have brought attention to the occurrence of severe muscle inflammation (myositis) related to COVID-19, potentially leading to multi-organ failure and increased mortality. Myositis is generally characterized by heightened serum creatine kinase (CK) levels. Acute myositis is characterized by an infiltration of viruses into calf muscle fibers, which may cause a subsequent inflammatory response leading to calf muscle pain. Symptomatic and supportive management, along with explanation and reassurance, is all that is required in managing this condition. While the association between myositis and severe outcomes has been recognized in adults, it remains less understood in the pediatric population. The current retrospective study, conducted at Policlinico San Marco University Hospital in Catania, aimed to analyze clinical and laboratory factors associated with myositis in pediatric patients with SARS-CoV-2 infection. Between January 2022 and January 2023, ten pediatric patients diagnosed with myositis and SARS-CoV-2 infection were evaluated. The study highlighted clinical manifestations such as fever, calf muscle pain, and abnormal gait. Lab results showed elevated CK levels among other findings. All patients underwent treatment, with the majority recovering without complications. A notable correlation was observed between CK levels, blood urea nitrogen (BUN), and the urea/creatinine ratio (UCR). The study also discusses potential pathophysiological mechanisms behind SARS-CoV-2's impact on skeletal muscles, emphasizing an indirect inflammatory response. Our findings underscore that while myositis in children with SARS-CoV-2 infection appears to follow a benign and self-limiting trajectory, it is crucial to monitor specific markers for early intervention and management. Further research is warranted to elucidate the underlying mechanisms and improve clinical outcomes.

Atención ambulatoria en el Hospital Municipal de Agudos de Bahía Blanca durante el primer año de la Pandemia Covid-19 / Outpatient (Ambulatory) Care at Bahía Blanca Municipal Acute Care Hospital During the first year of the Covid-19 Pandemic

Trabajo analítico, descriptivo, cualicuantitativo, que caracteriza los cambios estructurales en el HMALL llevados a cabo para la atención de pacientes ambulatorios durante la Pandemia Covid-19, describe las modificaciones en la oferta de servicios ambulatorios durante la Pandemia Covid-19 y analiza la demanda de servicios de salud ambulatorios no Covid-19 durante el año 2020.

Alergia e intolerancia a antiinflamatorios no esteroideos en pediatría / Allergy and intolerance to nonsteroidal anti-inflammatory drugs in children

Los antiinflamatorios no esteroideos son ampliamente recetados en niños. Constituyen la segunda causa de reacciones a medicamentos en pediatría después de los antibióticos betalactámicos; sin embargo, solo una parte de estas son reacciones de hipersensibilidad. La prevalencia de dichas reacciones a antiinflamatorios no esteroideos en niños es del 0,3 % y aumenta al 5 % en asmáticos.Los mecanismos fisiopatológicos involucrados (inhibición de la ciclooxigenasa, hipersensibilidad mediada por inmunoglobulina E, linfocitos T reactivos y/o afectación de la inmunidad innata) darán lugar a diferentes entidades clínicas con sintomatología dispar.La confusión con síntomas propios de procesos virales y la variabilidad clínica hacen del diagnóstico de certeza un verdadero desafío. Una historia clínica detallada, análisis de laboratorio, pruebas cutáneas y de provocación controlada permitirán definir estrategias para cada paciente en particular sin etiquetar como alérgico a un niño que no lo es ni exponer a riesgos innecesarios a quien está sensibilizado.

Nonsteroidal anti-inflammatory drugs are widely prescribed in children. They are the second cause of drug ́s reactions in pediatrics after beta-lactam antibiotics, however only a part of them are hypersensitivity reactions. The prevalence of these reactions to nonsteroidal anti-inflammatory drugs in children is 0.3 %, increasing to 5 % in asthmatics.The different physiopathological mechanisms involved (inhibition of cyclooxygenase, immunoglobulin E-mediated hypersensitivity, reactive T lymphocytes and/or disturbance of innate immunity) will cause different clinical entities with diverse symptoms.The confusion between the common symptoms of a viral infection and a hypersensitivity reaction, and the variability of the clinical presentations make diagnosis a real challenge.A detailed clinical history, laboratory, skin and controlled provocation tests will provide strategies for each patient, without labeling a child who is not an allergic one, or taking unnecessary risks with those who are sensitized.

Recupero de costos por pacientes atendidos por seguro social en el primer nivel de atención del Municipio de Bahía Blanca / Healthcare cost recovery for patients with social security in public primary care facilities of the city of Bahía Blanca

El objetivo del presente trabajo fue describir el proceso de recupero de costos implementados en el primer nivel de atención de la Municipalidad de Bahía Blanca y cuantificar los recursos obtenidos para el año 2015. Se trata de un trabajo cuantitativo de corte transversal. Se destacan como resultados la motivación del equipo de trabajo y el clima laboral que generó la puesta en marcha del proceso administrativo que permite el cobro de prestaciones de la seguridad social en el primer nivel de atención. También, posibilitó el mejoramiento de estructuras edilicias que no lograban su financiamiento a través del presupuesto municipal, y que representan un aliciente para el trabajo diario de los trabajadores de este nivel de atención. Se espera que resulte un estímulo importante para el ingreso y permanencia del recurso humano en el sistema de salud local.

Actualización en las recomendaciones del tratamiento del choque anafiláctico: novedades sobre el uso de adrenalina / Update on anaphylactic shock treatment recommendations: What's new in the use of epinephrine?

En 1998, la Sociedad Argentina de Pediatría publicó la recomendación del tratamiento del choque anafiláctico. Mientras en dicha recomendación se sugería el uso de adrenalina por vía subcutánea, actualmente se considera la vía intramuscular como la más adecuada. Aspectos farmacodinámicos determinan esta preferencia. Para el tratamiento extrahospitalario, el uso de autoinyectores de manera correcta puede colaborar en el control rápido y eficaz de la afección. El uso del resto de las medicaciones propuestas en la recomendación de 1998 se mantiene sin cambios.

In 1998, the Sociedad Argentina de Pediatría issued the recommendation of the treatment of anaphylactic shock. While this recommendation suggested the use of subcutaneous epinephrine, currently the intramuscular via is considered the most appropriate one. Pharmacological aspects determine this preference. For outpatient treatment, the correct use of autoinjectors can control anaphylaxis quickly and effectively. The use of other medications in the proposed 1998 recommendation remains unchanged.

Gestión de la comunicación en el primer nivel de atención de la ciudad de Bahía Blanca, 2014. Análisis desde la perspectiva de una situación de conflicto: la certificación de la libreta de asignación universal por hijo / Communication management at first level healthcare in the city of Bahía Blanca, 2014. Analysis from a conflict situation perspective: certification of the universal child allowancebooklet

La comunicación en el trabajo en terreno del sector salud es vital para realizar diagnósticos oportunos y tratamientos acordes al mismo en forma eficaz y segura. En estos ámbitos se generan conflictos por la tensión entre familias con una problemática de salud determinada y equipos de trabajo con una demanda creciente. Algunos de estos conflictos se expresan a nivel comunicacional, generando un terreno propicio de acción para mejorar la tarea. Una de las situaciones que produjo aumento de la demanda asistencial ha sido el trámite para el cobro de la Asignación Universal por Hijo, es decir la exigencia de un control anual de ciudadanos hasta 18 años de edad con certificación expresa de profesionales de la salud del ámbito público. Esta normativa genera fuerzas antagónicas entre la población usuaria del Sistema Público de Salud, que no logra conseguir turnos en tiempo y forma para su atención, y los equipos de salud, ya de por sí sobrecargados de trabajo burocrático y administrativo, sumado a su tarea específica de atención de la salud. Este trabajo pretende describir, luego del diagnóstico de situación realizado con la opinión de los profesionales del Sistema de Salud Municipal del ámbito de la Atención Primaria, algunas herramientas para mejorar la comunicación en los equipos de trabajo, hacia el interior y el exterior de los mismos, de manera tal de disminuir la conflictividad de situaciones como la confección de la Libreta de Asignación Universal por Hijo. Objetivos: Identificar y caracterizar aspectos comunicacionales institucionales en el ámbito de la Atención Primaria de la Salud de Bahía Blanca durante el proceso de confección de Libretas para el cobro de la Asignación Universal por Hijo. Materiales y Métodos: Es un trabajo analítico y descriptivo, de tipo etnográfico, que utiliza técnicas cualitativas recabando datos primarios a través de entrevistas semiestructuradas a Profesionales de la Salud del primer nivel de atención del Sistema Público de Salud (SPS) de la ciudad de Bahía Blanca. Resultados y Conclusiones: El estudio se desarrolló en tres etapas:Etapa I: Realización del diagnóstico de situación; Etapa II: Desarrollo de las Encuestas; Etapa III: Análisis de los Datos y elaboración de la Propuesta de Mejora. Se aprecia a través del desarrollo de este trabajo que las acciones de salud destinadas a cumplimentar los requisitos establecidos para el cobro de la AUH han generado situaciones de desborde de la demanda asistencial, disconfort en el equipo de salud y en la comunidad a la que asisten.

Communication when performing field work in the healthcare sector is vital for timely diagnosis and proper treatment in an efficient and safe manner. In these environments, conflicts arise due to the tension among families with a certain health problem and work teams with a growing demand. Some of these conflicts are expressed at the level of communication, thus generating a proper action environment to improve work. One of the situations that caused an increase in the demand for assistance has been the procedure to collect the Universal Child Allowance, i.e. the requirement of an annual health control of children up to 18 years old with an express certification issued by public healthcare professionals. This regulation generates antagonist strengths between users of the Public Health System, who cannot get timely medical appointments, and healthcare teams, already overburdened with bureaucratic and administrative work, in addition to their specific healthcare practice. This work is an attempt to describe, after the diagnosis of the situation carried out by surveying the Municipal Health System Primary Healthcare, some tools to improve communication in work teams, both inside and outside the teams so as to reduce the degree of conflict in situations such as the preparation of the Universal Child Allowance booklet. Objectives: To identify and characterize institutional communication aspects in Bahía Blanca Primary Healthcare area during the process of preparing booklets for collecting the Universal Child Allowance. Materials and Methods:This is an analytical, descriptive, ethnographic-like work that uses qualitative techniques by collecting primary data through semi-structured interviews to primary level healthcare professional of Bahía Blanca city Public Health System (SPS, according to the Spanish acronym). Results and Conclusions: The study was carried out in three stages: Stage I: Diagnosis of the situation; Stage II: Surveys; Stage III: Data analysis and drafting of improvement proposal. Throughout this work we have noticed that health actions for meeting the requirements set forth for collecting the Universal Child Allowance have generated situations of overburden in healthcare demand, discomfort in the healthcare team and also in the community they serve.
