Abstract The healthcare setting was important in the early spread of severe acute respiratory syndrome (SARS) in both Toronto and Taiwan. Healthcare workers, patients, and visitors were at increased risk for infection. Nonetheless, the ability of individual SARS patients to transmit disease was quite variable. Unrecognized SARS case-patients were a primary source of transmission and early detection and intervention were important to limit spread. Strict adherence to infection control precautions was essential in containing outbreaks. In addition, grouping patients into cohorts and limiting access to SARS patients minimized exposure opportunities. Given the difficulty in implementing several of these measures, controls were frequently adapted to the acuity of SARS care and level of transmission within facilities. Although these conclusions are based only on a retrospective analysis of events, applying the experiences of Toronto and Taiwan to SARS preparedness planning efforts will likely minimize future transmission within healthcare facilities.
In 1995, a total of 55 million persons aged > or =55 years lived in the United States. The members of this large and growing segment of the population are major consumers of health care. Their access to medical and dental preventive services contributes to their likelihood of healthy later years and influences their long-term impact on the health-care delivery system.1995-1997.This report summarizes data from the National Health Interview Survey (NHIS), the state-based Behavioral Risk Factor Surveillance System (BRFSS), and the Medicare Current Beneficiary Study (MCBS) to describe national, regional, and state-specific patterns of access to and use of preventive services among persons aged > or =55 years.During 1995-1997, approximately 90% of persons aged > or =55 years living in the United States reported having a regular source of health-care services. However, only 75%-80% reported receiving a routine checkup during the preceding 2 years. The estimated percentage of persons who reported not being able to receive medical care because of cost was highest for those aged 55-64 years. Within this age group, the percentage was highest among Hispanics (4%) and persons without a high school diploma. Approximately 11% of Medicare beneficiaries reported delaying care be cause of cost or because they had no particular source of care. Percentage estimates varied according to age, race/ethnicity, and sociodemographic status. Approximately 95% of persons aged > or =55 years reported having their blood pressure checked during the preceding 2 years, but only 85%-88% had received a cholesterol evaluation during the preceding 5 years. The percentage of women receiving breast and cervical cancer screening decreased with increasing age, and the percentage of persons aged > or =55 years who had received some form of screening for colorectal cancer was low approximately 25% for fecal occult blood testing (FOBT) and 45% for endoscopy. State-specific rates of compliance with vaccination recommendations among persons aged > or =65 years were higher for influenza vaccine (range: 54%-74%) than for pneumococcal vaccine (range: 32%-59%), and compliance increased with advancing age. State-specific estimates of the percentage of annual dental visits varied 40%-75%, and 41%-88% of persons aged > or =65 years reported not having dental insurance.Access to medical services among adults living in the United States is greater for persons aged > or =65 years, compared with those aged <65 years, presumably because of Medicare coverage. In contrast, use of dental services decreased, despite increased need for preventive and restorative dental care. Although Medicare covers many medical services for older adults, financial, personal, and physical barriers to both medical and dental care create racial, regional, and sociodemographic disparities in health status and use of health services in the United States.Continued surveillance of access to and use of health services among older adults (i.e., persons aged > or =65 years), as well as among persons aged 55-64 years, will help health-care providers target underserved groups, make Medicare coverage decisions, and develop public health programs to ensure equitable access to services and improve the health of older adults.
The separation of mental and physical health that exists in our health care and public health systems belies the fact that both exist within individuals in an exquisitely integrated fashion. This issue of Preventing Chronic Disease explores that integration. The definition of health provided by the constitution of World Organization is unambiguous in this regard: Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity (1). If we are to achieve this goal of complete well-being, we will have to bridge the chasms within our health care and public health systems.
Mental illnesses such as depression or anxiety affect an individual's ability to undertake health-promoting behaviors. Chronic diseases can have a profound impact on an individual's mental health; in turn, mental health status affects an individual's ability to participate in treatment and recovery. A group of mental health and public health professionals convened to develop a logic model for addressing mental health as it relates to chronic disease prevention and health promotion. The model provides details on inputs, activities, and desired outcomes, and the designers of the model welcome input from other mental health and public health practitioners.
In 2006, area physicians reported increases in upper respiratory symptoms in patients living in U.S. Federal Emergency Management Agency (FEMA)-supplied trailers following Hurricanes Katrina and Rita. One potential etiology to explain their symptoms included formaldehyde; however, formaldehyde levels in these occupied trailers were unknown. The objectives of our study were to identify formaldehyde levels in occupied trailers and to determine factors or characteristics of occupied trailers that could affect formaldehyde levels. A disproportionate random sample of 519 FEMA-supplied trailers was identified in Louisiana and Mississippi in November 2007. We collected and tested an air sample from each trailer for formaldehyde levels and administered a survey. Formaldehyde levels among all trailers in this study ranged from 3 parts per billion (ppb) to 590 ppb, with a geometric mean (GM) of 77 ppb [95% confidence interval (CI): 70-85; range: 3-590 ppb]. There were statistically significant differences in formaldehyde levels between trailer types (P < 0.01). The GM formaldehyde level was 81 ppb (95% CI: 72-92) among travel trailers (N = 360), 57 ppb (95% CI: 49-65) among mobile homes (N = 57), and 44 ppb (95% CI: 38-53) among park models (N = 44). Among travel trailers, formaldehyde levels varied significantly by brand. While formaldehyde levels varied by trailer type, all types tested had some levels ≥ 100 ppb.
Telah dilakukan penelitian terhadap DNA kromosom Endomycopsls fibuligera ITS.R.cc.54 yang dipotong dengan berbagai enzim restriksi yang bertujuan untuk mengetahui besar ukuran fragmen dan pola pemotongan. Dari hasil pemotongan tersebut dapat digunakan untuk mengetahui posisi relatif urutan nukleotida yang secara spesifik pada molekul DNA kromosom Endomycopsis fibuligera ITS.R.cc.64 dengan sisi pemotongan tertentu pada beberapa tempat yang berada pada ukuran fragmen dari masing-masing enzim restriksi.
