ERS guidelines on the assessment of cough

Abstract: ### Cough 1) All basic scientific articles should refer to cough as a three-phase motor act. For the purposes of acoustic recordings in clinical studies, however, cough should be described as a forced expulsive manoeuvre or manoeuvres against a closed glottis that are associated with a characteristic sound or sounds. 2) All scientific articles should include a clear definition of what the authors have used as their definition of cough. ### Capsaicin and citric acid inhalation cough challenge 1) The methodology for the performance of inhalation cough challenge should be standardised so as to facilitate universal interpretation and comparison of data generated by different laboratories. 2) Comprehensive normal ranges need to be developed using the standardised methodology advocated in the present document. 3) The single-breath concentration–response method using a flow-limited dosimeter is recommended for most experimental protocols. 4) Both C2 and C5 should be recorded. 5) Since there is wide inter-individual variation, cough challenge data have no intrinsic significance, but may usefully be used to follow change in cough reflex sensitivity in an individual. ### Cough induced by inhalation of aqueous solutions 1) Aerosolised aqueous solutions represent a useful experimental tool in cough research. 2) The cough challenge with ultrasonic distilled water (fog) is difficult to standardise since it is highly dependent upon nebuliser output. 3) Consideration should be given to potential adverse events, such as bronchoconstriction and cross-infection. ### Cough monitors 1) No cough monitor is currently the gold standard. 2) Monitors should be developed that are ambulatory, are capable of being digitally processed and permit prolonged (24-h) recording. 3) There is little to commend any particular method of quantifying cough over any other. ### Assessment of quality of life of patients with chronic cough 1) Cough can have profound effects on health status, which can be assessed by cough-specific health status questionnaires. 2) Cough visual analogue scale (VAS, 0–100 mm) should be used to assess cough severity in patients with chronic cough. 3) Patients with chronic cough should be assessed with cough-specific quality-of-life questionnaires in clinical studies. ### Animal models of cough 1) The most useful animal model of cough is …

An Improved Version of the Cervical Vertebral Maturation (CVM) Method for the Assessment of Mandibular Growth

Abstract: The present study aimed to provide a version of the Cervical Vertebral Maturation (CVM) method for the detection of the peak in mandibular growth based on the analysis of the second through fourth cervical vertebrae in a single cephalogram. The morphology of the bodies of the second (odontoid process, C2), third (C3), and fourth (C4) cervical vertebrae were analyzed in six consecutive cephalometric observations (T1 through T6) of 30 orthodontically untreated subjects. Observations for each subject consisted of two consecutive cephalograms comprising the interval of maximum mandibular growth (as assessed by means of the maximum increment in total mandibular length, Co-Gn), together with two earlier consecutive cephalograms and two later consecutive cephalograms. The analysis consisted of both visual and cephalometric appraisals of morphological characteristics of the three cervical vertebrae. The construction of the new version of the CVM method was based on the results of both ANOVA for repeated ...

Vegetarian, vegan diets and multiple health outcomes: A systematic review with meta-analysis of observational studies.

Abstract: Background: Beneficial effects of vegetarian and vegan diets on health outcomes have been supposed in previous studies. Objectives: Aim of this study was to clarify the association between vegetarian, vegan diets, risk factors for chronic diseases, risk of all-cause mortality, incidence, and mortality from cardio-cerebrovascular diseases, total cancer and specific type of cancer (colorectal, breast, prostate and lung), through meta-analysis. Methods: A comprehensive search of Medline, EMBASE, Scopus, The Cochrane Library, and Google Scholar was conducted. Results: Eighty-six cross-sectional and 10 cohort prospective studies were included. The overall analysis among cross-sectional studies reported significant reduced levels of body mass index, total cholesterol, LDL-cholesterol, and glucose levels in vegetarians and vegans versus omnivores. With regard to prospective cohort studies, the analysis showed a significant reduced risk of incidence and/or mortality from ischemic heart disease (RR 0.75; 9...
