Combustible and Electronic Tobacco and Marijuana Products in Hip-Hop Music Videos, 2013-2017

Importance: Hip-hop is the leading music genre in the United States and its fan base includes a large proportion of adolescents and young adults of all racial and ethnic groups, particularly minorities. The appearance of combustible and electronic tobacco and marijuana products, especially brand placement and use by popular and influential artists, may increase the risk of tobacco and marijuana use and decrease perceptions of harm. Objective: To assess the prevalence of the appearance and use of combustible and electronic tobacco and marijuana products, including brand placement, in leading hip-hop songs. Design, Setting, and Participants: Analysis of top 50 songs from 2013 to 2017 of Billboard magazine's weekly Hot R&B/Hip-Hop Songs with videos that included the appearance or use of combustible tobacco and marijuana products (manufactured cigarettes, cigars, hookah or waterpipe, pipe, hand-rolled tobacco and marijuana products, marijuana buds); appearance of exhaled smoke or vapor without an identifiable source product; appearance or use of electronic tobacco and marijuana products (eg, electronic cigarettes); tobacco or marijuana brand placement; appearance or use of combustible and electronic tobacco and marijuana by main or featured artist. Data were collected from December 6, 2017, to June 4, 2018. Main Outcomes and Measures: Prevalence of (1) appearance or use of combustible tobacco and marijuana products, (2) appearance of smoke or vapor, (3) appearance or use of electronic tobacco and marijuana products, (4) tobacco or marijuana brand placement, and (5) appearance or use of combustible and electronic tobacco and marijuana by main or featured artist. Probability of appearance or use of combustible and electronic tobacco and marijuana products by quartile of viewership of videos. Results: The proportion of leading hip-hop videos containing combustible use, electronic use, or smoke or vapor ranged from 40.2% (76 of 189) in 2015, to 50.7% (102 of 201) in 2016. For each year, the leading category of combustible use was hand-rolled products. The appearance of branded products increased from 0% in 2013 (0 of 82) to 9.9% in 2017 (10 of 101) for combustible products, and from 25.0% in 2013 (3 of 12) to 87.5% in 2017 (14 of 16) for electronic products. The prevalence of combustible or electronic product use or exhaled smoke or vapor increased by quartile of total number of views: 41.9% (8700 to 19 million views) among songs in the first quartile of viewership and 49.7% among songs in the fourth quartile of viewership (112 million to 4 billion views). Conclusions and Relevance: Combustible and electronic tobacco and marijuana use frequently occurred in popular hip-hop music videos. The genre's broad appeal, use of branded products by influential artists, and rise of electronic product and marijuana use may contribute to a growing public health concern of tobacco and marijuana use

Review article: A European perspective on wind and storm damage – from the meteorological background to index-based approaches to assess impacts

Wind and windstorms cause severe damage to natural and human-made environments. Thus, wind-related risk assessment is vital for the preparation and mitigation of calamities. However, the cascade of events leading to damage depends on many factors that are environment-specific and the available methods to address wind-related damage often require sophisticated analysis and specialization. Fortunately, simple indices and thresholds are as effective as complex mechanistic models for many applications. Nonetheless, the multitude of indices and thresholds available requires a careful selection process according to the target sector. Here, we first provide a basic background on wind and storm formation and characteristics, followed by a comprehensive collection of both indices and thresholds that can be used to predict the occurrence and magnitude of wind and storm damage. We focused on five key sectors: forests, urban areas, transport, agriculture and wind-based energy production. For each sector we described indices and thresholds relating to physical properties such as topography and land cover but also to economic aspects (e.g. disruptions in transportation or energy production). In the face of increased climatic variability, the promotion of more effective analysis of wind and storm damage could reduce the impact on society and the environment

Mutations in 3 genes (MKS3, CC2D2A and RPGRIP1L) cause COACH syndrome (Joubert syndrome with congenital hepatic fibrosis)

OBJECTIVE: To identify genetic causes of COACH syndrome BACKGROUND: COACH syndrome is a rare autosomal recessive disorder characterised by Cerebellar vermis hypoplasia, Oligophrenia (developmental delay/mental retardation), Ataxia, Coloboma, and Hepatic fibrosis. The vermis hypoplasia falls in a spectrum of mid-hindbrain malformation called the molar tooth sign (MTS), making COACH a Joubert syndrome related disorder (JSRD). METHODS: In a cohort of 251 families with JSRD, 26 subjects in 23 families met criteria for COACH syndrome, defined as JSRD plus clinically apparent liver disease. Diagnostic criteria for JSRD were clinical findings (intellectual impairment, hypotonia, ataxia) plus supportive brain imaging findings (MTS or cerebellar vermis hypoplasia). MKS3/TMEM67 was sequenced in all subjects for whom DNA was available. In COACH subjects without MKS3 mutations, CC2D2A, RPGRIP1L and CEP290 were also sequenced. RESUlTS: 19/23 families (83%) with COACH syndrome carried MKS3 mutations, compared to 2/209 (1%) with JSRD but no liver disease. Two other families with COACH carried CC2D2A mutations, one family carried RPGRIP1L mutations, and one lacked mutations in MKS3, CC2D2A, RPGRIP1L and CEP290. Liver biopsies from three subjects, each with mutations in one of the three genes, revealed changes within the congenital hepatic fibrosis/ductal plate malformation spectrum. In JSRD with and without liver disease, MKS3 mutations account for 21/232 families (9%). CONCLUSIONS: Mutations in MKS3 are responsible for the majority of COACH syndrome, with minor contributions from CC2D2A and RPGRIP1L; therefore, MKS3 should be the first gene tested in patients with JSRD plus liver disease and/or coloboma, followed by CC2D2A and RPGRIP1L

Differential expression of anterior gradient gene AGR2 in prostate cancer

<p>Abstract</p> <p>Background</p> <p>The protein AGR2 is a putative member of the protein disulfide isomerase family and was first identified as a homolog of the <it>Xenopus laevis </it>gene XAG-2. AGR2 has been implicated in a number of human cancers. In particular, AGR2 has previously been found to be one of several genes that encode secreted proteins showing increased expression in prostate cancer cells compared to normal prostatic epithelium.</p> <p>Methods</p> <p>Gene expression levels of AGR2 were examined in prostate cancer cells by microarray analysis. We further examined the relationship of AGR2 protein expression to histopathology and prostate cancer outcome on a population basis using tissue microarray technology.</p> <p>Results</p> <p>At the RNA and protein level, there was an increase in AGR2 expression in adenocarcinoma of the prostate compared to morphologically normal prostatic glandular epithelium. Using a tissue microarray, this enhanced AGR2 expression was seen as early as premalignant PIN lesions. Interestingly, within adenocarcinoma samples, there was a slight trend toward lower levels of AGR2 with increasing Gleason score. Consistent with this, relatively lower levels of AGR2 were highly predictive of disease recurrence in patients who had originally presented with high-stage primary prostate cancer (P = 0.009).</p> <p>Conclusions</p> <p>We have shown for the first time that despite an increase in AGR2 expression in prostate cancer compared to non-malignant cells, relatively lower levels of AGR2 are highly predictive of disease recurrence following radical prostatectomy.</p
