Genes regarding Chernobyl children

This survey aims to assess knowledge, attitude and stigma towards HIV patients, among medical students in Tuzla, Bosnia and Herzegovina. We also aimed to assess potential risk factors for HIV infection among fourth year medical students.
Data were collected from specific questionnaire that was completed by 171 students of the Faculty of Medicine, University of Tuzla. A multivariable logistic regression was performed.
Majority of students (79%) had a good knowledge of HIV, (median value of correct answers was 9 (95%) with at least 6 correct responses). Also, majority of students (73.6%) had a positive attitude towards HIV patients and the median positive value was 6 (95% CI 6-7). More than a third of students considered that all hospitalized patients should be tested for HIV. Total of 81% of students considered that they should inform the sexual partner of HIV positive patient, although she/he disagrees. 61.4% of students had a discriminatory attitude towards HIV, with the median values of 3 (95% CI 3-3). Multivariate regression analysis identified positive attitude towards HIV patients as an independent predictor for a non-discriminatory attitude. Moreover, an overall attitude towards HIV patients defines student`s determination to work with AIDS population. Male gender, and older age, were identified as predictors of risky behavior.
Preventive measures, including better HIV education, are crucial. Knowledge can increase awareness of HIV infection, decrease the incidence and reduce stigma towards HIV patients.

Tuberculosis (TB) continues to be a public health problem globally. The burden is further exacerbated in developing countries like Nigeria, by poor diagnosis, management and treatment, as well as rapid emergence of drug-resistant TB. This study was conducted to evaluate the prevalence of drug-resistant TB, determine the rpoB gene mutation patterns of Mycobacterium tuberculosis (MTB) and model the dynamics of multidrug resistant TB (MDR-TB) in Enugu, Nigeria.
A total of 868 samples, from patients accessing DOTS services in designated centres within the zone, were screened by sputum-smear microscopy, while 207 samples were screened by Nucleic Acid Amplification (Xpert® MTB/Rif) Test (NAAT). A deterministic model was formulated to study the transmission dynamics of TB and MDR-TB, using live data generated through epidemiological study.
The results showed TB prevalence values of 22.1% and 21.3% by sputum-smear and NAAT assays, respectively. Analysis of the rifampicin resistance patterns showed the highest occurrence of mutations (50%) along codons 523 - 527. Factors such as combination therapy, multiple therapy and compliance to treatment had influence on both prevalence and development of TB drug resistance in the population.
This first documentation of Rifampicin resistance patterns in MTB from Nigeria shows that a majority of rpoB gene mutations occurred along codons 523 to 527, contrary to the widely reported codon 531 mutation and that multiple interventions such as combination therapy, with good compliance to treatment are needed to reduce both prevalence and development of TB drug resistance in the population.

The clinical role of Leclercia adecarboxylata as an opportunistic pathogen in the context of human infections have been highlighted by multiple published case reports, describing these bacteria as novel or emerging pathogens.
The study included L. adecarboxylata isolates and laboratory data collected, corresponding to a 13-year time period (between 1 January 2005 and 31 December 2017). Presumptively identified L. adecarboxylata isolates were re-identified using VITEK 2 Compact ID/AST and MALDI-TOF MS analysis.
n = 34 isolates were verified by VITEK 2 system and MALDI-TOF. The fosfomycin-agar and CPS Elite agar were effective in the phenotypic differentiation of the isolates. N = 18 (52.9%) of L. adecarboxylata was considered as clinically significant pathogens (based on the clinical signs and symptoms), while n = 16 (47.1%) were considered as contaminants. These pathogens were isolated from wound/abscess samples (n = 9), urine samples (n = 6) and blood cultures (n = 3). 31 out of 34 isolates (91.2%) were potential of this organism as a pathogen.The existing knowledge is insufficient to explain some infection events of SARS-CoV-2, and new ideas about the transmission modes may be needed. The present study proposes that the RNAs of this virus might be infectious and that the transmission of these RNAs might be one route of transmission of SARS-CoV-2. A2ti2 I speculate that SARS-CoV-2 RNAs are infectious based on the following rationale and offer a putative mechanism RNA is the most important biomolecule of the novel coronavirus for expression and replication, free RNA strands of SARS-CoV-2 have the potential to remain suspended in the air and retain their biological activity, and some exogenous RNAs can enter the host cell after contact. Further studies are needed in order to verify this hypothesis. It is worthwhile to compare the effects of SARS-CoV-2 components (e.g., virus particles, positive RNA strands, negative RNA strands, and virus proteins) with symptoms to study the mechanism of asymptomatic infection. If additional detection results show that the proportion of RNA in the environment is higher than the proportion of RNA in the novel coronavirus particles, this would suggest the potential presence of free RNA genomes of SARS-CoV-2 in the environment. Research on the temporal and spatial distribution of infectious SARS-CoV-2 RNA strands is necessary. The nucleic acid test of SARS-CoV-2 should target not only positive RNA strands but also negative RNA strands. For medical purposes, studying environmental RNAs (eRNAs) is important. I believe that further investigation of the infection capabilities of viral RNAs will yield useful information.
