Abstract Background Congenital cytomegalovirus disease (cCMV) is common and can be fatal or cause severe sequelae. Circulating strains of cytomegalovirus carry a high number of variable or disrupted genes. One of these is UL146, a highly diverse gene with 14 distinct genotypes encoding a CXC-chemokine involved in viral dissemination. UL146 genotypes 5 and 6 lack the conserved ELR motif, potentially affecting strain virulence. Here, we investigate whether UL146 genotypes 5 and 6 were associated with congenital CMV infection. Methods Viral DNA was extracted and UL146 sequenced from 116 neonatal dried blood spots (DBS) stored in the Danish National Biobank since 1982 and linked to registered cCMV cases through a personal identifier. These sequences were compared to UL146 control sequences obtained from CMV DNA extracted from 83 urine samples from children with suspected bacterial urinary tract infections. Results Three non-ELR UL146 genotypes (5 and 6) were observed among the cases (2.6%) and two were observed among the controls (2.4%; P > 0.99). Additionally, no significant association with cCMV was found for the other 12 genotypes in a post-hoc analysis, although genotype 8 showed a tendency to be more frequent among cases with 12 observations against three (P = 0.10). All fourteen genotypes were found to have little intra-genotype variation. Viral load, gender, and sample age were not found to be associated with any particular UL146 genotype. Conclusions No particular UL146 genotype was associated with cCMV in this nationwide retrospective case-control study. Associations between CMV disease and disrupted or polymorph CMV genes among immunosuppressed people living with HIV/AIDS and transplant recipients should be investigated in future studies.

Harmful Effects

The real wealth of any nation and any region lies in the wellbeing of its people. The three main problems in the world, are known as three-P-Population, Poverty, and Pollution. Pollution is the main problem of the modern world. The technological inventions and progress has over powered nature, it has also resulted in the thoughtless exploitation of nature. Awareness by educating everyone, to value the nature and maintain the natural environment are important need. A study was conducted a 50 private and govt. female school students to measure the environmental values. Environmental Value Test (Shrivastav& Dubey, 1995) was used to assess the environmental value of the sample age range varied from 16-17 yrs. Findings of the study reveal that there is degree of high environmental value among both urban groups. Eco-club, Vanmahotsava, Exhibitions are popular means of creating awareness about environment. The need of the hour is to discuss environmental issues as our environmental issues, at global level as a sense of duty. To protect the environment from the adverse effects of pollution, many nations worldwide have enacted legislation to regulate various types of pollution to mitigate their harmful effects.

Abstract ObjectiveThe SARS-CoV-2 pandemic has prompted one of the most extensive and expeditious genomic sequencing efforts in history. Each viral genome is accompanied by a set of metadata which supplies important information such as the geographic origin of the sample, age of the host, and the lab at which the sample was sequenced, and is integral to epidemiological efforts and public health direction. Here, we interrogate some shortcomings of metadata within the GISAID database to raise awareness of common errors and inconsistencies that may affect data-driven analyses and provide some possible avenues for solutions.ResultsOur analysis reveals a startling prevalence of spelling errors and inconsistent naming conventions, which together occur in an estimated ~9.8% and ~11.6% of “originating labs” and “submitting labs” GISAID metadata categories respectively. We also find numerous ambiguous entries which provide very little information about the actual source of a sample and could easily associate with multiple sources worldwide. Importantly, all of these issues can impair the ability and accuracy of association studies by deceptively causing a group of samples to identify with multiple sources when they truly all identify with one source, or vice versa.

The Impact

Differences in socio-economic conditions, demographics, and infrastructural variances in the rural markets create substantial variances in the consumption patterns compared with the urban markets. As per a report of the World Bank, about 63 percent of the population resides in Bangladesh’s rural areas as it constitutes a bigger market for the consumption of different products. The researchers envision identifying the impact of packaging and labeling elements in the decision-making evaluation for different skincare products. The research exploration comprises of four objectives, i.e., perception and attitude towards packaging and labeling elements for the rural consumers, measuring the relative impact based on the demographical changes, determining the sensitivity towards branding elements and communication portrayed, and the ability in identifying the original skincare products in comparison with the copy products in the rural markets. The researchers conducted surveys in the Mymensingh, Netrokona, Jamalpur, and Sherpur Districts of the greater Mymensingh Division of Bangladesh. A total of 390 responses were selected based on the non-probability sampling frame. The target sample age group was chosen between 13 to 54 years. Researchers developed a questionnaire in combination with close-ended questions along with simple dichotomies. For analyzing the outcomes, the researchers have applied a statistical method of the “Z-test” Technique. The researchers identified that the packaging and labeling of skincare products influence rural consumers’ behavior. Different promotional strategies and trade marketing activities are recommended based on the findings, reinforcing the rural consumers’ acceptance of skincare products.

Perception Survey

IntroductionThe validated long Research Participant Perception Survey (RPPS-Long) elicits valuable data at modest response rates.MethodsTo address this limitation, we developed shorter RPPS-Ultrashort and RPPS-Short versions, fielded them with the RPPS-Long to a random sample of a national research volunteer registry, and assessed response and completion rates, test/retest reliability, and demographics.ResultsIn total, 2228 eligible registry members received survey links. Response rates were 64% (RPPS-Ultrashort), 63% (RPPS-Short), and 51% (RPPS-Long), respectively (p<0.001). Completion rates were 63%, 54%, and 37%, respectively (p<0.001). All surveys were reliable with Cronbach α=0.81, 0.84, and 0.87, respectively. Retest reliability was highest for RPPS-short (κ=0.85). Provision of compensation increased RPPS-short completion rate from 54% to 71% (p<0.001). Compensated respondents were younger (p<0.001), with greater minority representation (p=0.03).ConclusionsShorter surveys were reliable and produced higher response and completion rates then long surveys. Compensation further increased completion rates and shifted sample age and race profiles.
