New Strategies

In recent years, the drug resistant microorganisms are a serious and increasing public health problem. New strategies for controlling bacteria activity are urgently needed and nanomaterials can be a very promising approach, as the small size of the particle gives large surface area and consequently reactivity (and in many cases toxicity) increases substantially. The most tested metallic nanoparticles are silver, copper, gold, aluminum, titanium, iron, zinc, bismuth and others. Some of these metals have been coated onto several other materials. Another strategy is to incorporate these metals into a substrate such as polymethyl methacrylate forming organic-inorganic antimicrobial nanostructures. With respect to bacteria and fungi, the most frequent candidates for microbial experiments are: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia, Bacillus subtilis among other species. The antimicrobial potential of these nanostructured particles, their mechanism of action and health care applications are presented and discussed at length in this review.

AbstractKlebsiella pneumoniae is the causative agent of Klebsiella pneumonia and enteritis, and the prevalence of antibiotic resistant strains is becoming a serious public health problem. In this study, we isolated a novel strain of Paenibacillus polymyxa from the fecal extracts of healthy dogs that were challenged with K. pneumoniae. By combination of transposon mutagenesis and metabolic analysis, a nonribosomal peptide synthase gene cluster was identified to be involved in the antagonism, and the molecular weight of the compound was 1168.38 g/mol. These findings will enlarge the arsenal against drug-resistant pathogens.

Background: Healthcare-associated infections (HCAIs) occur when patients receiving treatment in a health care setting develop an infection. They represent a major public health problem, requiring the integration of clinical medicine, pathology, epidemiology, laboratory sciences, and, finally, forensic medicine. Methods: The determination of cause of death is fundamental not only in the cases of presumed malpractice to ascertain the causal link with any negligent behavior both of health facilities and of individual professionals, but also for epidemiological purposes since it may help to know the global burden of HCAIs, that remains undetermined because of the difficulty of gathering reliable diagnostic data. A complete methodological approach, integrating clinical data by means of autopsy and histological and laboratory findings aiming to identify and demonstrate the host response to infectious insult, is mandatory in HCAIs related deaths. Results: Important tasks for forensic specialists in hospitals and health services centers are the promotion of transparency and open communication by health-care workers on the risk of HCAIs, thus facilitating patients’ engagement and the implementation of educational interventions for professionals aimed to improve their knowledge and adherence to prevention and control measures. Conclusion: HCAIs are a major problem for patient safety in every health-care facility and system around the world and their control and prevention represent a challenging priority for healthcare institution and workers committed to making healthcare safer. Clinicians are at the forefront in the war against HCAIs, however, also forensic pathologists have a remarkable role.

The area of phytosynthesized nanomaterials is rapidly developing, with numerous studies being published yearly. The use of plant extracts is an alternative method to reduce the toxic potential of the nanomaterials and the interest in obtaining phytosynthesized nanoparticles is usually directed towards accessible and common plant species, ferns not being explored to their real potential in this field. The developed nanoparticles could benefit from their superior antimicrobial and antioxidant properties (compared with the nanoparticles obtained by other routes), thus proposing an important alternative against health care-associated and drug-resistant infections, as well as in other types of applications. The present review aims to summarize the explored application of ferns in nanotechnology and related areas, as well as the current bottlenecks and future perspectives, as emerging from the literature data.

Abstract Background The increasing spread of drug resistant gram-negative organisms is one of the major public health challenges. ESBL-producing Enterobacteriaceae has become the most common multi drug resistant pathogen in the last three decades. These organisms confer resistance to most beta-lactam antibiotics, including penicillins, third generation cephalosporins, monobactams and tazobactam. Methods The Tennessee Health Department (TDH) collaborated with CDC to pilot population based surveillance of ESBL producing organisms in Maury, Wayne, Lewis and Marshall Counties during October to December 2017. A case was defined as isolation of Escherichia coli, Klebsiella pneumoniae, or Klebsiella oxytoca resistant to at least one extended-spectrum cephalosporin (ceftazidime, cefotaxime or ceftriaxone) and non-resistant to all carbapenem antibiotics from urine or normally sterile body sites from a resident of the surveillance catchment area. A line list of ESBL-producing organisms was received from the labs that serve the catchment population. Case report forms were completed for the first ESBL culture collected from a single patient in a 30 day-period. Results A total of 154 cases were identified during the study period. E.coli constitutes 92.2% of the ESBL producing organisms followed by Klebsiella pneumonia (5.2%) and K. oxytoca (2.6%). The estimated annual incidence rate was 400.7 per 100,000 population which is more than twice of the average rates of other sites that conducted similar studies. The most common isolate source was urine (97%), and 81.2% of all cases were female. Patient ages ranged from 3-99 years, with average of 67 years. Thirty-two isolates underwent additional sequence typing and 76.7% (23) of the isolates were ST 131. 21 (91.3%) of ST-131 isolates were resistant to ciprofloxacin. Conclusion The study revealed that the incidence of ESBL producing organisms is very high in the Tennessee study area compared to other sites. The most common ESBL-producing pathogen was found to be ST 131 and most of these were resistant to ciprofloxacin suggesting that resistance to fluoroquinolone may be co-transmitted in ESBL producing pathogens through plasmids. Continued surveillance of molecular epidemiology is important to guide the prevention of the spread of drug resistant pathogens. Disclosures All Authors: No reported disclosures

Health Care Associated Infections

Health care–associated infections (HAIs) and drug-resistant pathogens have become a major health care issue with millions of reported cases every year. Advanced diagnostics would allow clinicians to more quickly determine the most effective treatment, reduce the nonspecific use of broad-spectrum antimicrobials, and facilitate enrollment in new antibiotic treatments. We present a new integrated system, polarization anisotropy diagnostics (PAD), for rapid detection of HAI pathogens. The PAD uses changes of fluorescence anisotropy when detection probes recognize target bacterial nucleic acids. The technology is inherently robust against environmental noise and economically scalable for parallel measurements. The assay is fast (2 hours) and performed on-site in a single-tube format. When applied to clinical samples obtained from interventional procedures, the PAD determined the overall bacterial burden, differentiated HAI bacterial species, and identified drug resistance and virulence status. The PAD system holds promise as a powerful tool for near-patient, rapid HAI testing.

Background: The burden of childhood disability as a public health problem in developing countries remains relatively unrecognized. One out of 750 children born in the world suffer from club foot among them 80% are in low and middle income countries. Most of these babies have limited access to receive effective treatment for their clubfoot due to lack o knowledge, awareness and some barriers. We actually don’t know the level of knowledge of parents who have child with clubfoot deformity. The purpose of this study was to assess the level of knowledge of parents who have children with clubfoot during clubfoot treatment. Materials and Methods: This cross sectional study was conducted among 102 parents who have children with clubfoot deformity during its treatment in a selected clinic. The samples were selected purposively from the clinics where clubfoot treatment was given and face to face interview was done by using semi-structured questionnaire. Results: The mean (±SD) age of the respondents were 24.7 (±6.0) years where 87.3% (n=89) respondents ware female and 59.8 %(n=61) respondent’s educational status ware up to primary level. About 44.1% respondents started treatment of their child within 6 months of birth and 33% within 6 to 12 months where 57% (n=58) respondents are referred by health care professional to this clinics. About 93.1% of parents (n=95) said that they knew nothing about clubfoot deformity before their child was diagnosed where 97% are aware after diagnosis of their child. About 93.1% respondents knew the best time for treatment initiation where 59.8% respondents know the correct follow up time of clubfoot management. In case of knowledge of parents’ roles in the treatment of clubfoot about 91.2%, parents have knowledge weekly visit for treatment and 86.3% know the plaster care where 52.9% (n=54) parents have lack of knowledge about how to use the brace Conclusion: There is need to improve the communication skills of clinicians/health care providers offering treatment to children with clubfoot at the Clinics. Need to share information with the parents about the condition. Finally, there is need to emphasize of educating parents about plaster care and how to use brace.
