AI Article Synopsis
- Research on drug use in rural and suburban China is limited, with most studies focusing on urban areas.
- A study in Dalian found that methamphetamine use was significantly lower in rural areas compared to urban and suburban areas, while heroin use was notably higher in suburban areas.
- The findings suggest that lower incomes and the outflow of the working-age population contribute to the reduced levels of drug use in rural areas, whereas suburban areas face challenges due to larger transient populations and less anti-drug initiatives.
Article Abstract
Illicit drug use in rural and suburban areas of China has not been studied extensively, as most studies have focused on illicit drug use in urban areas. To compare the differences between urban, suburban, and rural drug use, we collected influent samples from 19 urban, 9 suburban, and 18 rural wastewater treatment plants in Dalian, respectively. A method using solid-phase extraction combined with derivatization for gas chromatography -mass spectrometry analysis was applied to detect biomarker concentrations. The concentrations of methamphetamine and morphine ranged from 3.12 to 605 ng/L and < 2.35 to 198 ng/L, respectively. Norketamine was found in only four samples (5.56 to 14.5 ng/L), while 3,4-methylenedioxymethamphetamine and benzoylecgonine were not detected in any samples. Methamphetamine use in rural areas (16.3 mg/day/1000 inhabitant (inh), prevalence: 0.06%) was significantly lower than those in urban (77.1 mg/day/1000 inh, prevalence: 0.23%) and suburban (234 mg/day/1000 inh, prevalence: 0.70%) areas. Heroin use in suburban areas (57.6 mg/day/1000 inh, prevalence: 0.10%) was significantly higher than that in urban (13.9 mg/day/1000 inh, prevalence: 0.02%) and rural (8.68 mg/day/1000 inh, prevalence: 0.02%) areas. The results indicate relatively low levels of illicit drug use in rural areas of Dalian, related to low incomes and outflow of the working-age population. Illicit drug use was most prevalent in suburban areas of Dalian, which may be influenced by large floating populations and few anti-drug efforts in suburban areas.

The parasitic protozoa, (), is a model organism for one health because of its wide-ranging impacts on humans, wildlife, and domestic animals. Intermediate hosts, including white-tailed deer (), have been implicated in its maintenance. Prior analysis of seroprevalence in New York State deer focused on rural areas; however, the high density of domestic cats () in urban areas has been implicated in its spread amongst deer.

The genus Mittleman, 1950, belonging to the family Scincidae, exhibits considerable morphological convergence, complicating species delimitation and resulting in underestimated diversity. Currently, 41 species are formally recognized in this genus, although this figure likely underestimates its true richness. In this study, a new species of the genus , , is described from urban and suburban areas of Chengdu, Sichuan Province, Southwest China.

Background: Globally, the importance of dietary diversity in addressing malnutrition and promoting overall health is increasingly being recognized. However, increasing urbanization has led to shifts in dietary preferences, food consumption patterns, and a greater reliance on less nutritious processed foods. Efforts to address these challenges have been futile, as nutrition in peri-urban areas often receives less attention, with food and nutrition insecurity typically seen as a rural issue.

Objective: NICU graduates are frequently technology dependent including home oxygen, pulse oximetry, and/or nasogastric (NG) feedings. Primary care provider (PCP) perceptions, practices, and barriers to managing these infants are not well described, especially at altitude. We sought to 1) describe PCP comfort and 2) determine practices and barriers in managing this technology at higher altitude.
