Giardia lamblia is a common gastrointestinal pathogen but is not generally appreciated as a cause of severe illness. To describe the epidemiology of severe giardiasis, we reviewed data on hospital discharges from the United States and the state of Michigan and compared results for giardiasis with those for shigellosis. From 1979 to 1988, an estimated 4,600 persons were hospitalized for giardiasis annually in the United States; the incidence of giardiasis was 2.0 hospitalizations per 100,000 persons, compared with 2.4 hospitalizations per 100,000 persons for shigellosis. Rates of giardiasis were highest among children younger than 5 years old and women of childbearing age; the median length of hospital stay was 4 days (annual total, 23,238 days). Among residents of Michigan from 1983 to 1987, the average annual incidence of hospitalization was 1.4 per 100,000 persons for giardiasis, compared with 1.0 per 100,000 persons for shigellosis. Volume depletion was the most frequently listed codiagnosis (33.2%); 18.7% of children younger than 5 years old who had severe giardiasis had failure to thrive. Physicians should consider the diagnosis of giardiasis for persons with severe gastrointestinal illness.
Introduction/Objectives: Screening guidelines for breast, cervical, and colorectal cancer (CRC) are less clear for older adults due to the potential harms that may result from screening. Understanding older adults’ attitudes and perceptions, especially racial/ethnic minority and underserved adults, of cancer screening can help health care providers determine how best to communicate with older adults about cancer screening and screening cessation. The objective of this study was to determine how older adults primarily from minority/underserved backgrounds perceive cancer screening and overscreening. Methods: Four focus groups (n = 39) were conducted with adults (>=65 years of age) in 3 community settings in south-central Pennsylvania. Two focus groups were conducted in Spanish and translated to English upon transcription. Focus group data was managed and analyzed using QSR NVivo 12. Inductive thematic analysis was used to analyze the data where themes emerged following the coding process. Results: The focus group participants had an average age of 74 years and were primarily female (74%) and Hispanic (69%), with 69% reporting having less than a high school degree. Four key themes were identified from the focus groups: (1) importance of tailored and targeted education/information; (2) impact of physician/patient communication; (3) impact of barriers and facilitators to screening on cancer screening cessation; and (4) awareness of importance of screening. Participants were more likely to be agreeable to screening cessation if they received specific information regarding their health status and previous medical history from their physician as to why screening should be stopped and told by their physician that the screening decision is up to them. Conclusions: Older adults prefer individualized information from their physician in order to justify screening cessation but are against incorporating life expectancy into the discussion. Future research should focus on developing interventions to test the effectiveness of culturally tailored screening cessation messages for older adults.
IMPORTANCE National guidelines balance risks and benefits of population-level cancer screening among adults with average risk. Older adults are not recommended to receive routine screening, but many continue to be screened (ie, are overscreened). OBJECTIVE To assess the prevalence of overscreening for colorectal, cervical, and breast cancers among older adults as well as differences in overscreening by metropolitan status. DESIGN, SETTING, AND PARTICIPANTS The cross-sectional study examined responses to a telephone survey of 176 348 community-dwelling adults. Participants were included if they met age and sex criteria, and they were excluded from each cancer-specific subsample if they had a history of that cancer. Data came from the 2018 Behavioral Risk Factor Surveillance System, administered by the US Centers for Disease Control and Prevention. EXPOSURES Metropolitan status, according to whether participants lived in a metropolitan statistical area. MAIN OUTCOMES AND MEASURES Overscreening was assessed using US Preventive Services Task Force definitions, ie, whether participants self-reported having a screening after the recommended upper age limit for colorectal (75 years), cervical (65 years), or breast (74 years) cancer. RESULTS Of 176 348 participants (155 411 [88.1%] women; mean [SE] age, 75.0 [0.04] years; 150 871 [85.6%] non-Hispanic white; 60 456 [34.3%] with nonmetropolitan residence) the cancerspecific subsamples contained 20 937 [11.9%] men and 34 244 [19.4%] women for colorectal cancer, 82 811 [47.0%] women for cervical cancer, and 38 356 [21.8%] women for breast cancer. Overall, 9461 men (59.3%; 95% CI, 57.6%-61.1%) were overscreened for colorectal cancer; 14 463 women (56.2%; 95% CI, 54.7%-57.6%), for colorectal cancer; 31 988 women (45.8%; 95% CI, 44.9%-46.7%), for cervical cancer; and 26 198 women (74.1%; 95% CI, 73.0%-75.3%), for breast cancer. Overscreening was more common in metropolitan than nonmetropolitan areas for colorectal cancer among women (adjusted odds ratio [
