The Efficacy of Machine-Learning-Supported Smart System for Heart Disease Prediction.

The disease may be an explicit status that negatively affects human health. Cardiopathy is one of the common deadly diseases that is attributed to unhealthy human habits compared to alternative diseases. With the help of machine learning (ML) algorithms, heart disease can be noticed in a short time as well as at a low cost.

Population-Level Preparedness About Preventive Practices Against Coronavirus Disease 2019: A Cross-Sectional Study Among Adults in Bangladesh.

This study assessed the preparedness regarding the preventive practices toward the coronavirus disease 2019 (COVID-19) among the adult population in Bangladesh. Data were collected through an online survey with a sample size of 1,056. We constructed four variables (individual, household, economic, and community and social distancing) related to preparedness based on the principal component analysis of eight items.

Do knowledge and attitudes matter for preventive behavioral practices toward the COVID-19? A cross-sectional online survey among the adult population in Bangladesh.

The Government of Bangladesh has adopted several non-therapeutic measures to tackle the pandemic of SARS-CoV-2. However, the curve of COVID-19 positive cases has not significantly flattened yet, as the adoption of preventive measures by the general population is predominantly a behavioral phenomenon that is often influenced by people's knowledge and attitudes. This study aimed to assess the levels of knowledge, attitudes, and preventive behavioral practices toward COVID-19 and their interrelationships among the population of Bangladesh aged 18 years and above.

Plasmid interference for curing antibiotic resistance plasmids in vivo.

Antibiotic resistance increases the likelihood of death from infection by common pathogens such as Escherichia coli and Klebsiella pneumoniae in developed and developing countries alike. Most important modern antibiotic resistance genes spread between such species on self-transmissible (conjugative) plasmids. These plasmids are traditionally grouped on the basis of replicon incompatibility (Inc), which prevents coexistence of related plasmids in the same cell.

Quantitative multiplexed-tandem PCR for direct detection of bacteraemia in critically ill patients.

Culture remains the gold standard for diagnosis of blood stream infections (BSI), but its clinical utility is limited by slow turnaround times. Here we describe a method for rapid quantitative detection of bacterial DNA directly extracted from whole blood using a multiplexed tandem real-time PCR (MT-PCR) assay targeting Staphylococcus, Streptococcus, Pseudomonas, Enterococcus and Enterobacteriaceae 16S rDNA genes. Results were available less than 3.

In vitro volatile organic compound profiling using GC×GC-TOFMS to differentiate bacteria associated with lung infections: a proof-of-concept study.

Chronic pulmonary infections are the principal cause of morbidity and mortality in individuals with cystic fibrosis (CF). Due to the polymicrobial nature of these infections, the identification of the particular bacterial species responsible is an essential step in diagnosis and treatment. Current diagnostic procedures are time-consuming, and can also be expensive, invasive and unpleasant in the absence of spontaneously expectorated sputum.

Relative Strengths of Promoters Provided by Common Mobile Genetic Elements Associated with Resistance Gene Expression in Gram-Negative Bacteria.

Comparison of green fluorescent protein expression from outward-facing promoters (POUT) of ISAba1, ISEcp1, and ISAba125 revealed approximate equivalence in strength, intermediate between PCS (strong) and PCWTGN-10 (weak) class 1 integron promoter variants, >30-fold stronger than POUT of ISCR1, and >5 times stronger than Ptac. Consistent with its usual role, PCWTGN-10 produces more mRNA from a "downstream" gfp gene transcriptionally linked to a "usual" PCWTGN-10-associated gene cassette than does POUT of ISAba1.

Characterization of multidrug-resistant Klebsiella pneumoniae from Australia carrying blaNDM-1.

blaNDM genes, encoding metallo-β-lactamases providing resistance to carbapenems, have been reported in many locations since the initial report in 2008, including in several Enterobacteriaceae isolates in Australia/New Zealand. Here, we compare 4 additional carbapenem-resistant Klebsiella pneumoniae carrying blaNDM-1 isolated in Australia. Two are sequence type ST147, previously associated with blaNDM in Australia and elsewhere.

Genetic diversity and antibiotic resistance in Escherichia coli from environmental surface water in Dhaka City, Bangladesh.

The extended-spectrum β-lactamase gene bla(CTX-M-15) was almost ubiquitous in diverse antibiotic-resistant Escherichia coli isolated from surface water around Dhaka City, Bangladesh. Forty-eight isolates represented 34 multi-locus sequence types and a variety of plasmid replicons were identified in association with bla(CTX-M-15) and other resistance genes. This water is likely to be an important source of transmissible antibiotic resistance in Bangladesh.

Development of a multiplexed bead-based immunoassay for the simultaneous detection of antibodies to 17 pneumococcal proteins.

Presently, several pneumococcal proteins are being evaluated as potential vaccine candidates. Here, we gather novel insights in the immunogenicity of PLY, PsaA, PspA, PspC, NanA, Hyl, PpmA, SlrA, Eno, IgA1-protease, PdBD, BVH-3, SP1003, SP1633, SP1651, SP0189 and SP0376. We developed a multiplex bead-based immunoassay (xMAP(®) Technology, Luminex Corporation) to simultaneously quantify antibodies against these 17 pneumococcal proteins in serum.

Dependency of caspase-1 activation induced in macrophages by Listeria monocytogenes on cytolysin, listeriolysin O, after evasion from phagosome into the cytoplasm.

Listeriolysin O (LLO), an hly-encoded cytolysin from Listeria monocytogenes, plays an essential role in the entry of this pathogen into the macrophage cytoplasm and is also a key factor in inducing the production of IFN-gamma during the innate immune stage of infection. In this study, we examined the involvement of LLO in macrophage production of the IFN-gamma-inducing cytokines IL-12 and IL-18. Significant levels of IL-12 and IL-18 were produced by macrophages upon infection with wild-type L.

A significant increase in resistance to trimethoprim-sulphamethoxazole (from 52% to 72%, p < 0.01) and nalidixic acid (from 19% to 51%, p < 0.

Emergence of multidrug-resistant Salmonella enterica serotype Typhi with decreased ciprofloxacin susceptibility in Bangladesh.

During 1989-2002, we studied the antimicrobial resistance of 3928 blood culture isolates of Salmonella enterica serotype Typhi (S. Typhi) in Dhaka, Bangladesh. Overall 32% (1270) of the strains were multidrug-resistant (MDR, resistant to chloramphenicol, ampicillin and trimethoprim-sulphamethoxazole); first detected in 1990 (rate of 8%), increased in 1994 (44%), declined in 1996 (22%, P<0.

Decline in epidemic of multidrug resistant Salmonella typhi is not associated with increased incidence of antibiotic-susceptible strain in Bangladesh.

Since 1987, multidrug resistant (MDR) strains of Salmonella Typhi, resistant simultaneously to ampicillin, chloramphenicol and trimethoprim-sulfamethoxazole, have caused epidemics of severe typhoid fever in Asia and Africa. A retrospective analysis of blood culture results (1989-96) in a Diarrhoea Treatment Centre in Dhaka, Bangladesh detected MDR strains in 0.3% (8 of 2793) of samples in 1990.

First outbreak of dengue hemorrhagic fever, Bangladesh.

During the first countrywide outbreak of dengue hemorrhagic fever in Bangladesh, we conducted surveillance for dengue at a hospital in Dhaka. Of 176 patients, primarily adults, found positive for dengue, 60.2% had dengue fever, 39.

Rapid detection of Haemophilus influenzae type b in Bangladeshi children with pneumonia and meningitis by PCR and analysis of antimicrobial resistance.

A polymerase chain reaction (PCR) assay with primers from 'bexA' gene was compared with culture for the detection of Haemophilus influenzae type b (Hib) in clinical samples from children with pneumonia and meningitis. Of 200 sera (180 from pneumonia, 20 from non-pneumonia patients) tested by PCR (serum-PCR), Hib was detected in 15 of 16 blood culture-positive and in 6 blood culture-negative pneumonia cases. When compared with the results of blood culture, serum-PCR had sensitivity, specificity, and accuracy index of 93.
