General population's knowledge about the anatomical locations of organs and medical terms today and 50 years ago: a replication study.

ABSTRACT: Background: Physicians are frequently not aware that patients may not be familiar with the meaning of medical terms or have limited knowledge about the location of organs. These aspects of functional health competence require particular attention when designing communication curricula for undergraduate medical students. The aim of our study was to evaluate the knowledge of laypersons about the anatomical locations of organs and the definitions of commonly used medical terms as relevant aspects of health literacy. Furthermore, we wished to compare it with the knowledge of a historical patient cohort who performed this study 50 years ago. Methods: In this replication study, multiple-choice questionnaires with simple anatomy and common medical terms which were published in 1970 were distributed among a convenience sample of lay volunteers (n=537) from the streets of Hamburg, Germany. Sociodemographic data including sex, age, highest educational school achievement, occupation in a field associated with medicine, and German as first language were also collected. The percentage of laypersons' correct answers was compared to the percentage of correct answers of a historical patient cohort (n=234) published in 1970 to identify the development of health literacy as basis for curricular planning. Results: Laypersons showed significantly more correct answers in four of eight simple anatomical locations of organs (p<0.001). For seven commonly used medical terms laypersons only gave significantly more correct answers for the definitions of "jaundice" (p<0.001) and "diarrhoea" (p=0.001) compared to the historical cohort from 1970. Participants with a senior high school degree performed significantly better with respect to total scores of correct organ locations (p<0.001, d=0.35) and correct definitions of medical terms (p=0.001, d=0.30) than participants who completed junior high school. Conclusion: The definitions of common medical terms and the correct anatomical locations of organs by laypersons have increased during the past 50 years but could still need improvement by school education and media information of better quality. Medical educators should know about the low health literacy of laypersons with respect to these aspects to raise medical students' awareness for this problem and to provide communication training for medical students to use comprehensible language during history taking and shared decision making.

Project description:BackgroundThe "cancer analogy" is powerful for communicating risk to and organizing care for patients with diabetic foot syndrome. One potentially underappreciated similarity between cancer and foot ulcers is that both can recur at anatomical locations distinct from the primary occurrence, albeit with different physiological mechanisms. Few studies have characterized the location of diabetic foot ulcer recurrence, and these have been limited by considering only the first recurrent wound following a recent-healed wound. We therefore characterized the anatomical locations at which diabetic foot ulcers are likely to recur considering multiple wounds during follow-up and the locations of all prior wounds documented in the participant's history.MethodsWe completed a secondary analysis of existing data from a 129 participant multi-center study of participants in diabetic foot remission. The primary outcome was plantar foot ulceration, and each participant was followed for 34 weeks or until withdrawing consent, allowing characterization of all wounds occurring. We stratified the anatomical locations of wounds prior to the trial by the following outcome categories during the trial: no recurrence, recurrence to the same anatomical location, recurrence to a different anatomical location on the same foot, and recurrence to the contralateral foot.ResultsA large percentage (48%) of wounds recurred to the contralateral foot, and the proportion of subsequent foot ulcer to the contralateral limb was largely unaffected by the anatomical location of foot ulcer prior to the study. Only 17% of prior diabetic foot ulcers were followed by recurrence to the same anatomical location. Rates of recurrence remained high during treatment of a wound (0.41 foot ulcer/ulcer-year). Participants had documented wounds to 2.2 distinct anatomical locations on average, and more than 60% of participants had wounds to more than one plantar location by the end of the study.ConclusionsGiven the significant morbidity, mortality, and resource utilization associated with foot ulcer recidivism, quality and evidenced-based preventive care is essential. Our results better characterize the burden of recurrence and to what anatomy recurrence is most likely. These insights may benefit providers and patients alike for the provision of high-quality preventive care thereby resulting in reduced morbidity, mortality, and cost.Trial registrationThe study providing the data for this secondary analysis was registered on ClinicalTrials.gov (NCT02647346) on January 6, 2016. The study was retrospectively registered.

Project description:BackgroundMalaria remains a public health problem in Malaysia despite a decline in the number of cases in recent years. Public knowledge of malaria is essential to achieving and maintaining malaria elimination. Therefore, this survey assessed the prevalence of people who had ever heard of malaria, had correct knowledge of malaria transmission, symptoms, risk activities, and prevention measures in the Malaysian population, and identified the associated factors involved.MethodsThe data were obtained from the National Health and Morbidity Survey (NHMS) which was conducted from September to October 2020. A cross-sectional survey with five structured questionnaires using the method of computer-assisted telephone interviews (CATI) was used to collect data. The socio-demographic characteristics such as age, gender, ethnicity, nationality, marital status, educational level, and occupation were recorded. Data were analysed using STATA SE Version 16. Associations between variables were tested using chi-square and logistic regression, with the level of statistical significance set at p < 0.05.ResultsOut of 3085 respondents who participated in this survey, 2491 had ever heard of malaria with a prevalence of 76.1% (95% CI 70.5, 80.9). The prevalence of correct knowledge of malaria transmission was 53.9% (95% CI 50.2, 57.7), symptoms 24.1% (95% CI 21.2, 27.2), risk activities 34.0% (95% CI 29.3, 39.1) and prevention measures 59.7% (95% CI 55.5, 63.7). Multivariate analysis showed that age, ethnicity, and educational level were significantly associated with correct malaria transmission and risk activities. In addition, age and educational level were significantly associated with correct malaria symptoms. Subsequently, only the variable ethnicity showed a significant association with the correct malaria prevention measures.ConclusionIn general, the prevalence of ever heard of malaria was considered high since the survey was performed based on a non-specific malaria population. However, the prevalence of correct knowledge of malaria symptoms and risk activities were considered low. It is concluded that educational level is one of the major factors associated with correct malaria knowledge, along with age and ethnicity. Therefore, based on these findings, targeted intervention and innovation should be planned by malaria programme managers to sustain malaria elimination in Malaysia.

Project description:Arthropod cuticles have, in addition to chitin, many structural proteins belonging to diverse families. Information is sparse about how these different cuticular proteins contribute to the cuticle. Most cuticular proteins lack cysteine with the exception of two families (CPAP1 and CPAP3), recently described, and the one other that we now report on that has a motif of 16 amino acids first identified in a protein, Bc-NCP1, from the cuticle of nymphs of the cockroach, Blaberus craniifer (Jensen et al., 1997). This motif turns out to be present as two or three copies in one or two proteins in species from many orders of Hexapoda. We have named the family of cuticular proteins with this motif CPCFC, based on its unique feature of having two cysteines interrupted by five amino acids (C-X(5)-C). Analysis of the single member of the family in Anopheles gambiae (AgamCPCFC1) revealed that its mRNA is most abundant immediately following ecdysis in larvae, pupae and adults. The mRNA is localized primarily in epidermis that secretes hard cuticle, sclerites, setae, head capsules, appendages and spermatheca. EM immunolocalization revealed the presence of the protein, generally in endocuticle of legs and antennae. A phylogenetic analysis found proteins bearing this motif in 14 orders of Hexapoda, but not in some species for which there are complete genomic data. Proteins were much longer in Coleoptera and Diptera than in other orders. In contrast to the 1 and occasionally 2 copies in other species, a dragonfly, Ladona fulva, has at least 14 genes coding for family members. CPCFC proteins were present in four classes of Crustacea with 5 repeats in one species, and motifs that ended C-X(7)-C in Malacostraca. They were not detected, except as obvious contaminants, in any other arthropod subphyla or in any other phylum. The conservation of CPCFC proteins throughout the Pancrustacea and the small number of copies in individual species indicate that, when present, these proteins are serving important functions worthy of further study.
