The Value of Standardized Respiratory Rate Monitoring Exercises During Rheumatological Injection Procedures

The goal of this clinical trial is to demonstrate the non-inferiority of standardized breathing control exercises on perceived pain during rheumatological injections procedures compared to standard care consisting of the addition of a local anesthetic. The study population will consist of patients scheduled to undergo therapeutic ultrasound-guided joint or periarticular injection. The main question it aims to answer is: * Non-inferiority of breathing exercises compared to the addition of local anesthetic on pain and anxiety experienced during an infiltration procedure. * Correlation between the reduction in pain and anxiety experienced during a procedure and the cardiac coherence score obtained. Researchers will compare the anesthesia group (Arm A), which will receive local anesthesia with 5 cc of lidocaine before the infiltration procedure to the breathing group (Arm B), which will receive instructions before the injection procedure on how to perform 5-minute breathing cycles to facilitate the achievement of cardiac coherence to see if the pain perceived in Arm B is not greater than the pain perceived in Arm A. Participants will be kept blind to their randomization group. Arm A (anesthesia) will receive SHAM breathing exercises, while Arm B (breathing) will receive a placebo injection of anesthetic.

Early Lung Function Trajectories: Comparison Between Infants With and Without Intrauterine Growth Restriction.

During intrauterine life, some babies are smaller or grow less than expected. This fetal growth abnormality, called fetal growth restriction (FGR), can be diagnosed by ultrasound. Since there are currently no curative treatments for this condition, nor methods to optimize the growth of babies in the womb, the only effective strategy is intensive monitoring of fetal conditions, accompanied by early planning of delivery. The diagnosis of early FGR (i.e. diagnosed before 32 weeks of gestation) confers a greater risk of short- and long-term respiratory problems. The study aims to examine the association between parameters that can be assessed during pregnancy by ultrasound, such as the estimate of lung volumes, the thickness and contractility of the diaphragm, and cardiac kinetics, and any perinatal complications and respiratory function in the first years of life of premature infants, both with and without evidence of fetal growth pathology. Therefore, the study is divided into two phases: a prenatal and a postnatal phase. The study includes two groups of patients: 1. Study group: Fetuses and preterm infants with a prenatal history of FGR; 2. Control group: Preterm infants without a prenatal history of FGR followed during neonatal follow-up. Pregnant women with fetuses with FGR are followed at the Ultrasound clinics dedicated to Growth Pathology. These pregnancies usually receive weekly ultrasound monitoring, which includes a Doppler study of the maternal and fetal circulation and an estimate of fetal weight every two weeks. Cardiotocographic monitoring is also planned once or twice a week, depending on fetal well-being. The child will be assessed from a respiratory point of view during hospitalization and subsequently in the outpatient clinic, as required by clinical practice. He/she will undergo respiratory function tests. Visits are scheduled at 3, 6, 12 and 24 months of corrected age, during which at least two respiratory function tests will be performed. In addition, routine clinical data (personal data, medical history, blood tests, biological and instrumental tests) present in the medical record of the child will be collected. Data from preterm infants without fetal growth restriction will be collected after informed consent. These infants are routinely followed at our Institution and undergo clinical assessment and lung function tests in the first two years of life as previously indicated.
