Objective: We describe patients with MCS, the evolution of the Quick Environmental Exposure and Sensitivity Inventory (QEESI) score with a special focus on people whose fillings were removed. Methods: We have conducted a retrospective longitudinal cohort study in patients diagnosed with MCS and attended in the outpatient Internal Medicine department of the University Hospital of San Juan de Alicante, from January 1, 2008 to January 1, 2021. Sociodemographic, clinical, QEESI and treatment-related variables were collected. We performed descriptive and inferential analyses. Mixed linear models were used to analyze the QEESI. Calculations were carried out with an α error of 5%. Results: Thirty-three patients were included (72.7% women, mean age 56.2). MCS was mainly triggered by mercury (N = 20) and food intolerance (N = 22). The mean interval from symptoms onset was 120 months (SD 81.6). 114 QEESIs were analyzed: 82 (N = 17 without amalgams) and 32 (N = 16 with amalgams). In patients without amalgams, severity scores increased across all subscales except the masking index (vs. with amalgams). Mean scores for the group without amalgams (vs. with amalgams) were: chemical intolerance, 62.8 points (vs. 63.4 and 46.7);other intolerances, 52.7 points (vs. 62.8 and 50.3);symptom severity, 63.2 (vs. 76.7 and 63.3);masking index, 3.9 (vs. 3.2 and 2.8);and life impacts, 63.1 (vs. 58.4 and 49.8). Conclusion: The profile of patient with MCS is a middle-aged woman who is a frequent user of healthcare services, presents a long diagnostic delay and has borne a great personal, work and socioeconomic impact. The QEESI is useful for the clinical follow-up of patients, including the optimal treatment response in the case of amalgams. Clinical Significance: people affected by Multiple Chemical Sensitivity deserve the attention, understanding and help of health professionals and family members, to face an invisible illness for those who do not suffer from it.

BACKGROUND: prehospital medication is a reality, and the role of these therapies must be explored to assess their validity, especially for acute respiratory diseases, which are usually associated with increased morbidity. The aim of this study was to examine the association of prehospital medication use with mortality in patients with acute respiratory ***: A prospective, multicenter, emergency medical service(EMS) delivery cohort study was carried out in adults with unselected respiratory diseases managed by EMS who were transferred to the emergency department. From January 1, 2019, to October 31, 2023, six advanced life support units, thirty-eight basic life support units, and four hospitals in Spain participated in the study. Demographic data, vital signs, use of mechanical ventilation, prehospital respiratory diagnosis, and prehospital medication were collected. The primary outcome was 30-day in-hospital ***: A total of 961 patients were included, with a mortality rate of 17.5%(168 patients). Age, an increasing number of comorbidities, the use of invasive mechanical ventilation(IMV), the use of major analgesics, hypnotics, and bicarbonate were risk factors. In contrast, elevated systolic blood pressure and Glasgow Coma Scale scores were found to be protective factors against mortality. The predictive capacity of the model reached an area under the curve(AUC) of 0.857(95% confidence interval [95% CI] 0.827–0.888).CONCLUSION: Our data revealed that IMV, major analgesics, hypnotics and bicarbonate administration were associated with elevated mortality. Adding prehospital drug therapy information to demographic variables and vital signs could improve EMS decision-making, allowing a better characterization of patients at risk of clinical worsening.
