The urban heat island and its impact on heat waves and human health in Shanghai

Abstract: With global warming forecast to continue into the foreseeable future, heat waves are very likely to increase in both frequency and intensity. In urban regions, these future heat waves will be exacerbated by the urban heat island effect, and will have the potential to negatively influence the health and welfare of urban residents. In order to investigate the health effects of the urban heat island (UHI) in Shanghai, China, 30 years of meteorological records (1975-2004) were examined for 11 first- and second-order weather stations in and around Shanghai. Additionally, automatic weather observation data recorded in recent years as well as daily all-cause summer mortality counts in 11 urban, suburban, and exurban regions (1998-2004) in Shanghai have been used. The results show that different sites (city center or surroundings) have experienced different degrees of warming as a result of increasing urbanization. In turn, this has resulted in a more extensive urban heat island effect, causing additional hot days and heat waves in urban regions compared to rural locales. An examination of summer mortality rates in and around Shanghai yields heightened heat-related mortality in urban regions, and we conclude that the UHI is directly responsible, acting to worsen the adverse health effects from exposure to extreme thermal conditions.

Trends in Antimicrobial Drug Prescribing Among Office-Based Physicians in the United States

Abstract: Objective. —To assess changes in oral antimicrobial drug prescribing by office-based physicians from 1980 through 1992, with emphasis on the treatment of otitis media and sinusitis and on the possible impact of demographic variables on such use. Design. —The National Ambulatory Medical Care Survey is a sample survey of office-based physicians in the United States conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. Setting. —Physicians' offices. Patients or Other Participants. —Physicians sampled for the 1980,1985,1989, and 1992 National Ambulatory Medical Care Surveys, which included groups of 2959,5032,2540, and 3000 physicians, respectively. Sample physicians responding in 1980, 1985, 1989, and 1992 reported data for 46081, 71 594, 38384, and 34 606 sample office visits, respectively, including information on antimicrobial drug prescribing. Main Outcome Measure. —Trends in the antimicrobial drug prescription rates. Results. —From 1980 through 1992, increasing prescribing measured by the annual drug prescription rate per 1000 population, was found for the more expensive, broad-spectrum antimicrobial drugs, such as the cephalosporins; decreasing rates were observed for less expensive antimicrobial drugs with a narrower spectrum, such as the penicillins. No trend was found for trimethoprim-sulfamethoxazole, the erythromycins, or the tetracyclines. During the decade, an increasing trend in the visit rate to office-based physicians for otitis media was observed, while the visit rate for sinusitis among adults was found to be higher in 1992 than in each of the other study years. Conclusions. —The increased use of broader-spectrum and more expensive antimicrobial drugs have implications for all patients because of the impact on health care costs and the potential for the emergence of antimicrobial resistance. The data suggest that the incidence of otitis media and sinusitis is increasing. ( JAMA . 1995;273:214-219)

Maternal Infection Requiring Hospitalization During Pregnancy and Autism Spectrum Disorders

Abstract: Exposure to prenatal infection has been suggested to cause deficiencies in fetal neurodevelopment. In this study we included all children born in Denmark from 1980, through 2005. Diagnoses of autism spectrum disorders (ASDs) and maternal infection were obtained through nationwide registers. Data was analyzed using Cox proportional hazards regression. No association was found between any maternal infection and diagnosis of ASDs in the child when looking at the total period of pregnancy: adjusted hazard ratio = 1.14 (CI: 0.96–1.34). However, admission to hospital due to maternal viral infection in the first trimester and maternal bacterial infection in the second trimester were found to be associated with diagnosis of ASDs in the offspring, adjusted hazard ratio = 2.98 (CI: 1.29–7.15) and adjusted hazard ratio = 1.42 (CI: 1.08–1.87), respectively. Our results support prior hypotheses concerning early prenatal viral infection increasing the risk of ASDs.

Public Health Ethics: Mapping the Terrain

Abstract: , 30 (2002): 170 –178.© 2002 by the American Society of Law, Medicine & Ethics.ublic health ethics, like the field of public health itaddresses, traditionally has focused more on practiceand particular cases than on theory, with the resultthat some concepts, methods, and boundaries remain largelyundefined. This paper attempts to provide a rough concep-tual map of the terrain of public health ethics. We begin bybriefly defining public health and identifying general fea-tures of the field that are particularly relevant for a discussionof public health ethics.Public health is primarily concerned with the health ofthe entire population, rather than the health of individuals.Its features include an emphasis on the promotion of healthand the prevention of disease and disability; the collectionand use of epidemiological data, population surveillance,and other forms of empirical quantitative assessment; a rec-ognition of the multidimensional nature of the determinantsof health; and a focus on the complex interactions of manyfactors — biological, behavioral, social, and environmental— in developing effective interventions.How can we distinguish public health from medicine?While medicine focuses on the treatment and cure of indi-vidual patients, public health aims to understand andameliorate the causes of disease and disability in a popula-tion. In addition, whereas the physician-patient relationshipis at the center of medicine, public health involves interac-tions and relationships among many professionals andmembers of the community as well as agencies of govern-ment in the development, implementation, and assessmentof interventions. From this starting point, we can suggestthat public health systems consist of all the people and ac-tions, including laws, policies, practices, and activities, thathave the primary purpose of protecting and improving thehealth of the public.

Clostridium difficile infection in patients discharged from US short-stay hospitals, 1996-2003.

Abstract: US hospital discharges for which Clostridium difficile-associated disease (CDAD) was listed as any diagnosis doubled from 82,000 (95% confidence interval [CI] 71,000-94,000) or 31/100,000 population in 1996 to 178,000 (95% CI 151,000-205,000) or 61/100,000 in 2003; this increase was significant between 2000 and 2003 (slope of linear trend 9.48; 95% CI 6.16-12.80, p = 0.01). The overall rate during this period was severalfold higher in persons >65 years of age (228/100,000) than in the age group with the next highest rate, 45-64 years (40/100,000; p < or = 0.001). CDAD appears to be increasing rapidly in the United States and is disproportionately affecting older persons. Clinicians should be aware of the increasing risk for CDAD and make efforts to control transmission of C. difficile and prevent disease.
