La spirometria nel bambino collaborante
La spirometria fornisce al medico l’opportunità di accertare la normalità ed il grado di anomalia della funzione respiratoria. Oggi è disponibile una grande varietà di attrezzature computerizzate per l’esecuzione della spirometria in età pediatrica e, in particolare, gli apparecchi che si basano sulla misura del flusso mediante pneumotacografo o turbina sono di facile uso ambulatoriale.
I principali parametri misurati sono: FVC, FEV1, PEF, FEF25-75 ed il rapporto FEV1/FVC %. Attraverso l’esame spirometrico è possibile identificare almeno 3 pattern di condizione respiratoria patologica:
1) la disfunzione ventilatoria di tipo ostruttivo;
2) la disfunzione ventilatoria di tipo restrittivo;
3) l’ostruzione al flusso di aria lungo le vie aeree centrali e periferiche.
Il test di broncodilatazione è una prova essenziale nella valutazione di reversibilità dell’ostruzione.
spirometria, asma, fisiopatologia respiratoria.Spirometry provides the physician the opportunity to verify the normality and the degree of abnormality of the respiratory function. Today a wide variety of computer equipment for the execution of spirometry in children is available. In particular, devices based on the measurement of the flow through the pneumotachograph or the turbine, are easy to use in outpatient clinic setting.
The main parameters measured are: FVC, FEV1, PEF, FEF25-75 and FEV1/FVC % ratio. At least three patterns of pathological respiratory condition can be identified through spirometry:
1) obstructive ventilatory dysfunction;
2) restrictive ventilatory dysfunction;
3) obstruction to airflow along the central and peripheral airways.
The bronchodilation test is essential in the evaluation of the bronchoreversibilit
ChatGPT in scientific research: a guide to informed use
Using ChatGPT in scientific research offers revolutionary opportunities thanks to its natural language interaction capabilities and production of coherent and sophisticated text.Artificial intelligence can automate activities such as information synthesis and schematization, improving scientific communication and computer code writing.However, the lack of a complete understanding of context, the risk of spreading misleading information, and the possibility of plagiarism represent some of the biggest limitations in the current use of this technology.The role of human experience remains fundamental for in-depth understanding of context, exercising critical thinking, and ensuring respect for the ethical principles of scientific research.A responsible and aware use of tools such as ChatGPT can offer great benefits to the scientific community, but it is essential to remember that these tools are only a support and cannot replace human judgment and experience

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
