Sexually Transmitted Diseases (STDs)

High rates of unprotected sexual behavior in adolescents result in millions of cases of STDs in the world. This chapter reviews factors inducing high STD rates, specific STDs, and their management based on 2010 U.S. Centers for Disease Control and Prevention (CDC) STD guidelines. Clinicians should screen all their sexually active adolescent patients for STDs and provide preventive education as well as treatment measures

Sexually Transmitted Diseases in Adolescence

High rates of unprotected sexual behavior in adolescents result in millions of sexually transmitted diseases (STDs) in the world. This paper reviews factors inducing high STD rates, specific STDs, and their management based on 2010 US Centers for Disease and Prevention (CDC) STD guidelines.

A communal catalogue reveals Earth's multiscale microbial diversity

Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.Peer reviewe

In Defense of Slavery: An Exploration of Queen Anne's County Slave Owners 1820-1840

In August 1831, Nat Turner's rebellion shocked slaveowners in the South, but the reverberations of his massacre were also felt throughout the Chesapeake region. Maryland slaveowners reacted to the rebellion through legislative action that limited the freedoms of slaves and free blacks in the 1830s. However, restrictive legislation that would have completely revoked slaveowners' rights to manumit their slaves did not pass. This thesis examines records from Queen Anne's County in order to explain why slaveowners would support the existence of manumission throughout their state. In this thesis, slaveowners' relationships to and uses of manumission are made clear using personal collections, newspapers, and land records. This thesis examines documents in the Poplar Grove Collection at the Maryland State Archives, to suggest the value of community studies and analysis of documents from a specific place and time. This thesis reveals the economic and social control manumissions provided for Maryland slaveowners, which was exerted over slaves and free blacks, in the aftermath of one of the most remembered slave rebellions in American history. Finally, Queen Anne's County records create a more nuanced picture of how Maryland slaveowners thought of freedom and citizenship, particularly through their use of paternalistic and proslavery rhetoric

Is Europe facing an opioid epidemic: what does European monitoring data tell us?

This paper addresses the question of whether Europe is facing an opioid epidemic and utilizes data from the European monitoring system on opioid use, harms and availability, to help assess the situation. Data sources covering the last decade on overdose deaths, drug treatment entrants and drug-related emergencies suggest that the health burden associated with opioid use is mostly related to the consumption of heroin - and to a lesser extent diverted opioid substitution treatment medications - and that it is primarily affecting an ageing cohort of vulnerable users, with little evidence of an increase in initiation. While opioid-related deaths are currently at much lower levels than in the United States, they still represent a large preventable health burden with differences across EU countries. There is also increasing concern related to the high availability of heroin, illicitly produced synthetic opioids and diverted opioid pain medications on the European drugs market. Trends in the latter categories are poorly monitored and we may miss signs of emerging problems. Moreover, the economic recession following the COVID-19 pandemic has a potential to lead to resurgence in opioid use and harms. SIGNIFICANCE: This paper looks at data from the European monitoring system to address the question of whether Europe is facing an opioid epidemic. It reviews available health and supply side indicators, considering the limitations of each data source. A summary of the available evidence would suggest that while opioid-related deaths in Europe represent a large preventable health burden with differences across EU countries, Europe as a whole is not facing an opioid crisis of the size and nature seen in the US
