Enhancing respiratory physiology education: innovative wet spirometer modifications for hands-on learning.

The use of wet spirometers, although once common, has greatly declined because these devices measure only static lung volumes and students often face technical issues in their use. In this study, the wet spirometer has been modified to investigate the fundamental laws of flow and different types of lung disease. This modification was achieved by changing the dimensions of the device, printing a scale on the bell, and attaching an airflow control system (ACS) between the corrugated tube and hollow tube of the inner cylinder. The ACS allowed for flow control during the exercises. Two exercises were performed: exercise I compared the parameters measured by the wet spirometer, modified spirometer, and computerized spirometer to determine the suitability of the modification, while exercise II tested the variables affecting flow. These exercises introduce students to data collection, analysis, and the use of statistical tests as they compare various spirometers. Additionally, students gain valuable experience in experimental design by conducting diverse experiments that investigate factors influencing flow dynamics. By plotting the results and participating in small group discussions, students can apply flow principles in respiratory and circulatory systems, offering a hands-on experience that integrates physics and physiology. The modified spirometer facilitated multifaceted topic exploration, surpassing the traditional wet spirometer's capabilities.NEW & NOTEWORTHY This activity involves cost-effective modifications to the wet spirometer, broadening its applicability. These modifications effectively address student challenges associated with wet spirometer handling and enhance comprehension of fluid dynamics, all without the need for costly simulations, wet experiments, or fragile instruments. By offering a hands-on experience without traditional limitations, our modified spirometer provides an accessible and engaging approach to respiratory physiology education.

Prevalence of menopausal symptoms among women in Vadodara, Central Gujarat: The urban-rural divide.

Aim: The aim of this article is to estimate prevalence of menopausal symptoms among women in the menopausal age group and study the urban-rural differences. Methods and Design: Analytical cross-sectional study conducted in rural and urban field practice areas of a tertiary care center affiliated to Medical College, where 290 women (145 each from urban and rural areas) were interviewed to measure prevalence of menopausal symptoms. Forty-one symptoms were divided into 'Psycho-somatic' (17 symptoms), 'genito-urinary (9 symptoms)' and musculo-skeletal (5 symptoms) domains. The prevalence of each of these symptoms is reported as proportion and the differences in the median scores in the two groups were tested using Mann-Whitney U test. Results: From among 145 women each, in urban and rural settings, most common psychosomatic symptoms were physical exhaustion-fatigue (73.1%), difficulty climbing stairs (59.3%), sleep problems (45.2%), body ache (43.4%), and hot flushes (41.4%). Among the urban participants, most common was physical exhaustion (42.1%), difficulty climbing stairs (62.1%), anger (46.9%), sleep problems (45.5%), and irritability (42.1%), while among the rural participants they were physical exhaustion (66.2%), difficulty climbing stairs (56.6%), insomnia (54.5%), and body ache (46.2%). Most common genito-urinary symptoms overall and in rural areas were urinary urgency (35.9% and 38.6%), increased frequency of urine (31.7% and 37.2%) and incontinence (30% and 35.2% respectively). Among the urban women, common symptoms were urinary urgency (33.1%) followed by itching of private parts (30.3%) and increased frequency of urination (26.2%). Among musculo-skeletal symptoms, joint pain (74.1%, 74.5%, 73.8%) was the most common symptom followed by joint and muscular discomfort (71.7%, 73.8%, 69.7%) among the overall, urban and rural participants. There was a significant difference in the median psychosomatic score as per the symptoms experienced by the urban and rural participants (U = 36, Z statistic = 2.31, and P = 0.02). However, there was no significant difference in the scores for genito-urinary and musculo-skeletal symptoms; thereby, median scores under both these domains were almost similar in both urban and rural groups. Conclusion: There was significant difference in the median psychosomatic score as per the symptoms experienced by the urban and rural participants however; there was no significant difference in genito-urinary and musculo-skeletal symptom scores.
