The stigma associated with substance use disorder (SUD) harms the lives of people who use drugs (PWUD). Perceptions and projections such as PWUD are unclean, dangerous, noncompliant, or at fault for their addiction are unfounded and can harm the person's quality of life, impacting all social determinants of health. Stigmatic behaviors displayed in the healthcare setting directly influence the ability of the person with SUD to engage fully in their care as feelings of trust are replaced by shame.

Since 2004, the US Centers for Disease Control and Prevention (CDC) Influenza Division (ID) has supported seven countries in the Eastern Mediterranean region and the World Health Organization Regional Office for the Eastern Mediterranean to establish and strengthen influenza surveillance. The substantial growth of influenza surveillance capacities in the region demonstrates a commitment by governments to strengthen national programs and contribute to global surveillance. The full value of surveillance data is in its use to guide local public health decisions.

Background: Pair bonding with a reproductive partner is rare among mammals but is an important feature of human social behavior. Decades of research on monogamous prairie voles (Microtus ochrogaster), along with comparative studies using the related non-bonding meadow vole (M. pennsylvanicus), have revealed many of the neural and molecular mechanisms necessary for pair-bond formation in that species.

Article Synopsis
  • Whooping cough, primarily caused by Bordetella pertussis, has seen a resurgence in the U.S., highlighting the need to study the chromosome structural fluidity of its strains, which involves rearrangement and deletion.
  • Researchers analyzed complete genome sequences from 167 species isolates and 469 other isolates to understand the patterns of chromosome rearrangement among related pathogens in the Bordetella genus.
  • The study found that large inversions in gene order are mainly observed in species with multiple insertion sequence (IS) elements, indicating that while some species show less chromosomal diversity, they still experience similar mutations in gene order.

Despite high vaccine coverage, pertussis cases in the United States have increased over the last decade. Growing evidence suggests that disease resurgence results, in part, from genetic divergence of circulating strain populations away from vaccine references. The United States employs acellular vaccines exclusively, and current isolates are predominantly deficient in at least one immunogen, pertactin (Prn).

Despite high pertussis vaccine coverage, reported cases of whooping cough (pertussis) have increased over the last decade in the United States and other developed countries. Although is well known for its limited gene sequence variation, recent advances in long-read sequencing technology have begun to reveal genomic structural heterogeneity among otherwise indistinguishable isolates, even within geographically or temporally defined epidemics. We have compared rearrangements among complete genome assemblies from 257 isolates to examine the potential evolution of the chromosomal structure in a pathogen with minimal gene nucleotide sequence diversity.

Many veterans returning from service in Afghanistan or Iraq suffer from post-traumatic stress disorder or mild traumatic brain injury. Treating these conditions can be challenging because of high rates of relapse and associated memory impairments. We report on a pilot study that assessed the utility of mobile health (mHealth) technologies, including personal digital assistant-based ecological momentary assessment and two-way interactive text (SMS) messaging, for providing treatment feedback to clinicians, encouraging and motivating veterans throughout treatment, and monitoring participants for relapse after treatment discharge.

Background: The prairie vole (Microtus ochrogaster) is an emerging rodent model for investigating the genetics, evolution and molecular mechanisms of social behavior. Though a karyotype for the prairie vole has been reported and low-resolution comparative cytogenetic analyses have been done in this species, other basic genetic resources for this species, such as a genetic linkage map, are lacking.

Results: Here we report the construction of a genome-wide linkage map of the prairie vole.

Inversion polymorphisms have been linked to a variety of fundamental biological and evolutionary processes. Yet few studies have used large-scale genomic sequencing to directly compare the haplotypes associated with the standard and inverted chromosome arrangements. Here we describe the targeted genomic sequencing and comparison of haplotypes representing alternative arrangements of a common inversion polymorphism linked to a suite of phenotypes in the white-throated sparrow (Zonotrichia albicollis).

Bitter taste perception likely evolved as a protective mechanism against the ingestion of harmful compounds in food. The evolution of the taste receptor type 2 (TAS2R) gene family, which encodes the chemoreceptors that are directly responsible for the detection of bitter compounds, has therefore been of considerable interest. Though TAS2R repertoires have been characterized for a number of species, to date the complement of TAS2Rs from just one bird, the chicken, which had a notably small number of TAS2Rs, has been established.

A hallmark feature of the male-specific region of the human Y chromosome is the presence of large and near-identical palindromes. These palindromes are maintained in a state of near identity via gene conversion between the arms of the palindrome, and both neutral and selection-based theories have been proposed to explain their enrichment on the human Y and X chromosomes. While those proposed theories would be applicable to sex chromosomes in other species, it has not been established whether near-identical palindromes are a common feature of sex chromosomes in a broader range of taxa, including other tetrapods.

Background: The prairie vole (Microtus ochrogaster) is a premier animal model for understanding the genetic and neurological basis of social behaviors. Unlike other biomedical models, prairie voles display a rich repertoire of social behaviors including the formation of long-term pair bonds and biparental care. However, due to a lack of genomic resources for this species, studies have been limited to a handful of candidate genes.
