Improving health literacy of antifungal use-Comparison of the readability of antifungal medicines information from Australia, EU, UK, and US of 16 antifungal agents across 5 classes (allylamines, azoles, echinocandins, polyenes, and others).

Adherence to antifungals is poor in high endemic regions where antifungal resistance is high. Poor readability of prescription/over-the-counter (OTC) antifungals may contribute to poor adherence, due to the patient not fully understanding the purpose, importance, and dosage of their antifungal medicine. As there are no reports on the readability of antifungals, this study examined the readability of patient-facing antifungal information. Antifungals (n = 16; five classes [allylamines, azoles, echinocandins, polyenes, and others-flucytosine and griseofulvin]) were selected. Readability of four sources of information, (i) summary of product characteristics, (ii) patient information leaflets (PILs), (iii) OTC patient information, and (iv) patient web-based information, was calculated using Readable software, to obtain readability scores [(i) Flesch Reading Ease [FRE], (ii) Flesch-Kinkaid Grade Level [FKGL], (iii) Gunning Fog Index, and (iv) Simple Measure of Gobbledygook (SMOG) Index) and text metrics [word count, sentence count, words/sentence, and syllables/word]. PILs, web-based resources, and OTC patient information had good readability (FRE mean ± sd = 52.8 ± 6.7, 58.6 ± 6.9, and 57.3 ± 7.4, respectively), just falling short of the ≥ 60 target. For FKGL (target ≤ 8.0), PILs, web-based resources, and OTC patient information also had good readability (mean ± sd = 8.5 ± 1.0, 7.2 ± 0.86, and 7.8 ± 0.1, respectively). Improved readability scores observed correlate with reduced words, words/sentence and syllables/word. Improving readability may lead to improved patient health literacy. Healthcare professionals, academics, and publishers preparing written materials regarding antifungals for the lay/patient community are encouraged to employ readability calculators to check the readability of their work, so that the final material is within recommended readability reference parameters, to support the health literacy of their patients/readers.

Yeast and mould infections can be difficult-to-treat, due to resistance. Our study shows that patient information on antifungals is fairly easy-to-read. Such information helps the patient know how best to take the medicine and help avoid resistance. Authors should always try to write clearly for patients.

Infection Dynamics of Aspergillus fumigatus in Adults with Cystic Fibrosis (CF).

OBJECTIVE: Aspergillus fumigatus (A. fumigatus) has emerged as a significant pathogen in patients with cystic fibrosis (CF) and currently is within the top five isolated organisms reported in several international CF patient registries. A. fumigatus has been attributed to disease progression, although its role remains controversial. There is a paucity of reports on its infection dynamics, it was the aim of this study to examine time to first laboratory reports of A. fumigatus acquisition and to correlate this with patient gender and cystic fibrosis transmembrane conductance regulator (CFTR) mutation type. METHODS: One hundred adult (≥ 18 years) CF patients were examined (50 females, 50 males; mean age 24.6 years ± 6.25 (SD), median age 24 years; maximum age 76 years). CFTR mutation groups consisted (i) F508del/F508del homozygous (n = 45), (ii) F508del/other heterozygous (n = 45) and (iii) others (n = 10). CFTR mutation type, patient gender, presence/absence of A. fumigatus and time (months) to first isolation of A. fumigatus were examined. RESULTS: Microbiological data was examined from 100 patients from birth to present (31/12/2021), equating to 2455 patient years. A. fumigatus was isolated from 66/100 (66%) adult CF patients; (i) F508del/F508del homozygous (82%; 37/45), (ii) F508del/other heterozygous (56%; 25/45) and (iii) others (40%; 4/10). Within the F508del/other heterozygous group, 14 mutations were noted on the second allele, with R560T and R117H collectively accounting for 36% of the second mutations. Four unique allele/allele mutations were noted in the Other Mutations category. There was a trend to a higher A. fumigatus acquisition in F508del/F508del homozygous patients than with F508del/other patients (p = 0.0529). Of the 66 patients who were positive for A. fumigatus, 35(53%) were male and 31(47%) were female. The median and mean time to first isolation of A. fumigatus in all A. fumigatus-positive patients was 119.5 months and 128 months, respectively, shortest time was 12 months, longest time 288 months. There was a statistical significance in time-to-first isolation in relation to CFTR mutation group (p = 0.0272), whereby F508del homozygous individuals had their first isolation of A. fumigatus at 116.8 ± 7.9 months (mean ± standard error of the mean (SEM)) and F508del heterozygous patients had their first isolate of A. fumigatus at 150.4 months ± 13.7 months (mean ± SEM), approximately 2.75 years after their F508del homozygous peers. There was no significant difference (p = 0.12) in time to first acquisiton between males and females, whereby males had their first A. fumigatus isolate at 118 ± 9.4 months, whereas females had their first A. fumigatus isolate at 140 ± 10.8 months. The highest rate of first A. fumigatus isolation was from 4 years until 16 years and by the age of 16 years, approximately 85% of A. fumigatus-positive patients had recorded their first A. fumigatus isolate. CONCLUSION: To minimise the risk of first acquisition of A. fumigatus, it is important that infection prevention educational messaging is delivered in the paediatric clinic, to enhance health literacy around A. fumigatus acquisition.

What is the Perceived Role of the Dietitian Amongst People with Cystic Fibrosis? Results of an International survey.

Cystic fibrosis (CF) is a chronic condition requiring continued input from the CF dietitian as an integral part of the CF multidisciplinary team. In recent years, the longer life expectancy experienced by people with CF (PwCF) means that nutrition advice and therapy are evolving from a focus on nutrition support to prevention and management of comorbidities. Little has been reported regarding the perceived role of the CF dietitian amongst PwCF. We report the responses to 11 questions that were part of a larger international survey distributed to members of national CF charities in 2018-2019. These questions evaluated PwCFs' perspectives on (i) the importance of the CF diet, (ii) how often PwCF obtain dietary/nutritional advice from their dietitian, (iii) the perceived reliability of information given by the dietitian, (iv) other sources of CF information and their perceived reliability, and (v) how CF nutrition/diet, as well as CF-related diabetes, ranked as research priorities. There were 295 respondents from 13 countries. Almost half of the respondents (46.8%) contacted their CF dietitian on a frequent/more regular basis, compared to medical/scientific journals/medical/scientific search engines. The CF dietitian was considered a reliable source of information, as 84% of the respondents indicated that the information provided was very/generally reliable. At a time when CF care and expectations are changing rapidly, PwCF are in need of trusted and reliable information to make positive changes in lifestyle and habits. Dietitians working with PwCF should appreciate the pivotal and valued role they perform as purveyors of robust evidence-based information to this chronic disease population.

Vaccination terminology: A revised glossary of key terms including lay person's definitions.

WHAT IS KNOWN AND OBJECTIVE: There has been a paucity of vaccine and vaccine-related definitions within the scientific and medical peer-reviewed literature, particularly with the arrival of COVID-19. Therefore, it was the aim of this commentary to collate definitions to 44 vaccine- and vaccinology-related key terms, from four international and respected sources of information (where available), including (i) the World Health Organisation (WHO), (ii) the US Centers for Disease Control and Prevention (CDC), (iii) The Department of Health, Government of Australia and (iv) the European Union. In addition, it was a further aim to develop a lay person's definition to each of these 44 key terms, to act as a published and citeable reference point for pharmacists and other healthcare professionals, when communicating with patients and other public-facing stakeholders. COMMENT: Definitions are important in health care in order to (i) provide concise insight on a specific topic, (ii) provide a common understanding and (iii) set reference points to allow the adoption of a standard uniform approach. WHAT IS NEW AND CONCLUSION: The collation of definitions of key vaccine terms was compiled from four respected sources of information. A glossary of 44 key terms was produced to help pharmacists and other healthcare professionals explain such terms professionally, as well as to patient stakeholders in lay person's vocabulary. These lay definitions had superior readability metrics than definitions from any of the four professional sources, indicating their suitability for engagement with patient-facing stakeholders. Understanding the barriers to vaccine uptake is crucial for health professionals and policymakers to achieve improved uptake rates. This commentary has aimed at adding value to healthcare professionals and patients, by providing an up-to-date glossary of several professional definitions, from respected sources, as well as an accompanying lay definition to support the healthcare professional-patient communicative interface. Vaccines have become an important preventative tool, particularly in the context of the COVID-19 pandemic, to help mitigate disease severity and to help control the pandemic locally, nationally and internationally. Accessible and robust definitions help inform the dialogue to achieve this goal and the avoidance of obscurum per obscurius.

A doggy tale: Risk of zoonotic infection with Bordetella bronchiseptica for cystic fibrosis (CF) patients from live licenced bacterial veterinary vaccines for cats and dogs.

WHAT IS KNOWN AND OBJECTIVE: Live-attenuated bacterial veterinary vaccines can constitute an infection risk for individuals with any defect in their phagocytic function, including chronic granulomatous disease, leukocyte adhesion deficiency, myeloperoxidase deficiency, as well as Chediak-Higashi syndrome, from accidental acquisition of licenced attenuated live bacterial vaccine, at vaccination or from their vaccinated pet. Ownership of small companion animals, including cats and dogs, is popular within the cystic fibrosis (CF) community. These animals require vaccines as part of their routine care, which may involve live viral and bacterial vaccines, with potential for infection in the CF owner. This report examines the scope of current canine and feline vaccines, with particular emphasis on veterinary vaccination strategies against the Gram-negative pathogen, Bordetella bronchiseptica and describes new vaccine innovations offering protection to both pet and CF owner. COMMENT: The Gram-negative bacterium, Bordetella bronchoseptica, may cause respiratory disease in small companion animals, as well as in certain human vulnerable groups, including those with CF. Live licenced veterinary bacterial vaccines for Bordetella bronchiseptica (Kennel Cough) are available for cats and dogs, which are an infection concern for humans with CF who may come into contact with vaccinated animals. Live licenced veterinary bacterial vaccines for Bordetella bronchiseptica (Kennel Cough) are available for intranasal administration to cats and dogs. These vaccines require a withdrawal period of vaccinated animal from vulnerable owner, ranging from 35 days - 11 weeks. Recently, a new dead IM vaccine is now available not requiring exclusion of the vaccinated pet from CF owner. WHAT IS NEW & CONCLUSION: CF pharmacists, hospital pharmacists and community pharmacists are important custodians of vaccine-related advice to people with CF, who are frequently consulted for such advice. Pharmacists should be aware of the recent innovations in veterinary medicines, so that they can give appropriate advice to people with CF when asked. Immunocompromised patients, that is those with CF or those with any defect in their phagocytic function (chronic granulomatous disease, leukocyte adhesion deficiency, myeloperoxidase deficiency, Chediak-Higashi syndrome) should avoid exposure to live veterinary bacterial vaccines and seek animal vaccination utilising non-live vaccines. Most importantly, this manuscript highlights the development of a new veterinary vaccine for dogs, which we want to make the CF healthcare community aware of, which is an acellular dead vaccine, so that those patients with dogs needing annual vaccination can select this vaccine pathway, thereby minimising risk of infection from the vaccine strains and avoiding the social exclusion between CF patient and their pet. CF patients should understand the potential infection implications of live-attenuated viral and bacterial strains as vaccines, whether these are small companion animals, exotic animals or large farm animals. Patients should make their veterinarian aware of their CF status, so that a safe and efficacious vaccine strategy is used, both mitigating the potential infection risks from live vaccine components with the CF patient, but simultaneously offering maximum immunological protection to the animal.

Improving direct pharmacist counseling rates for oral oncolytic medications at an outpatient oncology clinic.

BACKGROUND: Due to the increasing prevalence of oral oncolytic utilization for patients with malignancy, implementation of strategies for increased monitoring and patient safety have become a necessity. Our focus was on the American Society of Clinical Oncology's Quality Oncology Practice Initiative (QOPI) standards of care, standard 2.3, and its requirement for patient counseling prior to first administration of oral oncolytic therapy. OBJECTIVE: To assess the implementation of a workflow improvement strategy to determine its effect on the number of patients reached for pharmacist counseling prior to first dose of oral oncolytic medications. METHODS: In this quasi-experimental quality improvement study, we formed a multidisciplinary group to develop and implement a workflow improvement process. This process was focused on a redistribution of workflow and the implementation of new technology within EPIC Beacon. RESULTS: A total of 86 patients were identified as eligible for counseling (38 pre-intervention, 48 post-intervention). There was a statistically significant increase in number of eligible patients counseled in the post-intervention period as compared to the pre-intervention period (100% vs. 86.84%; 95% CI = -0.212, -0.205; P = 0.017). There were no significant differences observed in the number of patients counseled in-person or patients counseled prior first dose. CONCLUSION: Our intervention showed a 100% rate of counsel in the post-intervention period. Further work needs to be done to improve the number of these patients we reach prior to them taking their first dose of medication, as well as the number of patients we are able to counsel face-to-face.

Improving COVID-19 vaccine-related health literacy and vaccine uptake in patients: Comparison on the readability of patient information leaflets of approved COVID-19 vaccines.

WHAT IS KNOWN AND OBJECTIVE: Preparation of patient-facing materials of a complex topic, such as describing new vaccines for COVID-19, is difficult to accomplish. This study examined the readability of patient information leaflets accompanying approved COVID-19 vaccines. COMMENT: Readability of patient-facing literature by the medicines regulator in the United States and the United Kingdom describing the recently US (FDA) and UK (MHRA) COVID-19 approved vaccines (Pfizer/BioNTech, AstraZeneca, Moderna) was assessed employing 10 metrics. Analyses showed that showed that this material had a Flesch Ease of Reading score of 53.5 and 54, respectively and a Flesch-Kincaid reading age of between 7th and 8th Grade (12-13 year olds) and between 8th and 9th Grade (13-14 year olds), respectively. When compared to a recent study on COVID-19 information on healthcare websites, the vaccine literature readability was favourable. WHAT IS NEW & CONCLUSION: Adoption of readability calculators and scrutiny of materials of their readability will help authors develop materials with improved understanding for COVID-19 vaccine recipients, carers and family, potentially leading to improved health literacy and vaccine uptake.

Does Bordetella pertussis vaccine offer any cross-protection against Bordetella bronchiseptica? Implications for pet owners with cystic fibrosis.

WHAT IS KNOWN AND OBJECTIVE: The Gram-negative bacterium, Bordetella bronchiseptica, causes lower airway respiratory disease in people with cystic fibrosis (CF), as well as in companion animals, especially dogs. Presently, there are several acellular vaccines available for B. pertussis but no vaccine available for B. bronchiseptica. However given the shared protein homology between these two closely related species, we wished to explore whether pertussis vaccines may offer some cross-protection against B. bronchiseptica. COMMENT: Bordetella pertussis and B. bronchiseptica are closely related phylogenetically, as well as sharing protein homology in several pertussis vaccine components, including (i) pertussis toxin (PT), (ii) filamentous haemagglutinin (FHA), (iii) pertactin and (iv) fimbriae (types 2 and 3). Given that pertussis vaccine contains cross-reactive antigens with B. bronchiseptica, licensed pertussis vaccines may therefore offer cross-protection against B. bronchiseptica. WHAT IS NEW AND CONCLUSION: Cystic fibrosis pet owners should ensure that they have an up-to-date vaccination record relating to their pertussis vaccine. Although no monovalent human pertussis vaccines are currently available, licensed non-live booster vaccines for B. pertussis are available for individuals in the age range >10 years old. People with CF should ensure that they are adequately and currently protected against pertussis, to avoid whooping cough, which may also offer some cross-protection against B. bronchiseptica and therefore help further mitigate the risk of zoonotic infection of this organism from pets to their owners.

Improving meningococcal MenACWY and 4CMenB/meningococcal group B vaccine-related health literacy in patients: Importance of readability of pharmaceutical Patient Leaflets.

WHAT IS KNOWN AND OBJECTIVE: Patient information leaflets (PILs) or Patient Leaflets (PLs) formally accompany dispensed medicines and are intended to provide the patient with information on how to use the medicine safely. To date, there have been no studies that have examined the readability of meningococcal vaccine patient-facing information, including information contained within the vaccine PIL. Given the role of pharmacists in presenting PILs to patients, it was, therefore, the aim of this study to quantitatively analyse the readability of Patient Leaflets, which accompany licensed meningococcal vaccines in the UK and US and to compare PILs to vaccine pharmaceutical manufacturers' summary of product characteristics (SPC), as well as other patient-facing vaccine-related information. METHODS: Five sources of meningococcal vaccine information were examined for the licensed meningococcal vaccines in the UK (Bexsero, Menveo, Menitorix, Trumenba, Nimenrix & NeisVac-C) and in the United States (Bexsero, Menveo, Trumenba, Menactra, Menomune-A/C/Y/W-135, Menquadfi), including as follows: (i) SPC (Electronic Medicines Compendium, UK), (ii) Package Insert (FDA; USA), (iii) Patient Leaflet (Electronic Medicines Compendium, UK), (iv) Vaccine pharmaceutical websites and (v) government web resources. Readability was examined employing 10 readability metrics, including the Flesch Reading Ease and the Flesch-Kincaid Grade level. RESULTS AND DISCUSSION: The information source with the greatest readability scores was the UK Patient Leaflet, which had a mean Flesch Reading Ease score of 58.1 and a mean Flesch-Kincaid Grade score of 7.3, followed by the US Department of Health & Human Services patient-facing website for vaccines (55.9 & 8, respectively), followed by the US Centers for Disease Control and Prevention Vaccine Information Statement (47.3 & 9.4, respectively). Pharmaceutical patient-facing websites for meningococcal vaccines had mean scores of 44.6 and 9.9, respectively. When compared with UK Patient Leaflets, pharmaceutical websites were statistically different with poorer readability with both Flesch Reading Ease and Flesch-Kincaid Grade Level indices (p = 0.02 & p = 0.04, respectively). WHAT IS NEW AND CONCLUSION: Pharmaceutical meningococcal vaccine PILs were easily read and had statistically significant good readability scores in comparison with vaccine SPCs and US Package Inserts, pharmaceutical product websites and other government patient-facing meningococcal vaccine information. Preparation of patient-facing materials of a complex topic, such as describing meningococcal vaccines, is difficult to accomplish. Although there is a plurality of sources of information through websites and social media, PILs are one of the few sources that are provided directly to patients. This underpins the potential importance of PILs and the importance of their readability. Adoption of readability calculators and scrutiny of materials for their readability will help authors develop materials with improved understanding for vaccine recipients, potentially leading to improved health literacy and vaccine uptake. Renewed efforts should be sought to promote the information within the PIL, thereby maximizing the value of this resource with vaccine recipients, their carers and family.

"Pathogen Eradication" and "Emerging Pathogens": Difficult Definitions in Cystic Fibrosis.

Infection is a common complication of cystic fibrosis (CF) airway disease. Current treatment approaches include early intervention with the intent to eradicate pathogens in the hope of delaying the development of chronic infection and the chronic use of aerosolized antibiotics to suppress infection. The use of molecules that help restore CFTR (cystic fibrosis transmembrane conductance regulator) function, modulate pulmonary inflammation, or improve pulmonary clearance may also influence the microbial communities in the airways. As the pipeline of these new entities continues to expand, it is important to define when key pathogens are eradicated from the lungs of CF patients and, equally important, when new pathogens might emerge as a result of these novel therapies.

Snow angels - the microbiology of freshly fallen snow: implications for immunocompromised patients.

The frequency of seasonal snowfall results in the transient covering of gardens/amenity sites/open public spaces, which encourages recreational interaction mainly with children. No data is available demonstrating the microbiological composition of such fallen snow and therefore a study was undertaken to examine the microbiology of snow from 37 sites, estimating (i) total viable count (TVC), (ii) identification of bacteria, and (iii) the presence of Pseudomonas aeruginosa. Mean TVC count of 8.3 colony-forming units (cfu)/ml snow melt water, 51.7 cfu/ml, 865 cfu/ml and 2,197 cfu/ml, was obtained for public amenity sites, domestic gardens, public open spaces and melting snow from public footpaths, respectively. No bacterial organisms (<10 cfu/ml) were detected in 5/14 (35.7%) open public spaces, 2/5 (40%) amenity sites and in 1/10 (10%) domestic gardens. Pseudomonas aeruginosa was not detected from any snow sample examined. Bacterial diversity consisted of 15 bacterial species (11 Gram-positive/four Gram-negative). The six Gram-positive genera identified from snow were Actinomyces, Bacillus, Brevibacillus, Micrococcus, Staphylococcus and Streptococcus. The four Gram-negative genera identified were Enterobacter, Pantoea, Pseudomonas and Xanthomonas. Bacillus licheniformis was the most commonly isolated organism from snow; it was isolated from every snow type. Snow may contain a diverse range of bacteria, many of which are capable of causing human infections.

Laboratory Diagnosis and Characterization of Fungal Disease in Patients with Cystic Fibrosis (CF): A Survey of Current UK Practice in a Cohort of Clinical Microbiology Laboratories.

There is much uncertainty as to how fungal disease is diagnosed and characterized in patients with cystic fibrosis (CF). A 19-question anonymous electronic questionnaire was developed and distributed to ascertain current practice in clinical microbiology laboratories providing a fungal laboratory service to CF centres in the UK. Analyses of responses identified the following: (1) current UK laboratory practice, in general, follows the current guidelines, but the scope and diversity of what is currently being delivered by laboratories far exceeds what is detailed in the guidelines; (2) there is a lack of standardization of fungal tests amongst laboratories, outside of the current guidelines; (3) both the UK CF Trust Laboratory Standards for Processing Microbiological Samples from People with Cystic Fibrosis and the US Cumulative Techniques and Procedures in Clinical Microbiology (Cumitech) Guidelines 43 Cystic Fibrosis Microbiology need to be updated to reflect both new methodological innovations, as well as better knowledge of fungal disease pathophysiology in CF; (4) there is a need for clinical medicine to decide upon a stratification strategy for the provision of new fungal assays that will add value to the physician in the optimal management of CF patients; (5) there is also a need to rationale what assays should be performed at local laboratory level and those which are best served at National Mycology Reference Laboratory level; and (6) further research is required in developing laboratory assays, which will help ascertain the clinical importance of 'old' fungal pathogens, as well as 'emerging' fungal pathogens.

Biocontrol of Burkholderia cepacia complex bacteria and bacterial phytopathogens by Bdellovibrio bacteriovorus.

Bdellovibrio and like organisms are predatory bacteria that have the unusual property of using the cytoplasmic constituents of other Gram-negative bacteria as nutrients. These predators may thus provide an alternative approach to the biocontrol of human and plant pathogens. Predators were isolated on Burkholderia cenocepacia K56-2 and J2315 as prey cells, in enrichment cultures with soil and sewage. Three isolates (DM7C, DM8A, and DM11A) were identified as Bdellovibrio bacteriovorus on the basis of morphology, a periplasmic life cycle, and 16S rRNA gene sequencing. The prey range of these isolates was tested on Burkholderia cepacia complex bacteria and several phytopathogenic bacteria of agricultural importance. Of 31 strains of the Burkholderia cepacia complex tested, only 4 were resistant to predation by strain DM7C. A subset of 9 of the prey tested were also susceptible to strains DM8A and DM11A. Of 12 phytopathogens tested, 4 were resistant to strains DM7C and DM8A, and only 2 were resistant to strain DM11A. Thus, Bdellovibrio bacteriovorus strains retrieved from environmental samples on 2 Burkholderia cenocepacia isolates from cystic fibrosis patients did not distinguish in their prey range between other isolates of that pathogen or phytopathogens. Such strains hold promise as potential wide-spectrum biocontrol agents.

Survival dynamics of cystic fibrosis-related Gram-negative bacterial pathogens (Pseudomonas aeruginosa and Burkholderia cenocepacia) in Dead Sea and Atlantic Ocean waters.

Clinical cystic fibrosis (CF) Pseudomonas aeruginosa (n=6) and Burkholderia cenocepacia (n=4) were inoculated in marine brines from the Dead Sea and the Atlantic Ocean and their survival was monitored over a 1 month duration. In Dead Sea samples, all P. aeruginosa and B. cenocepacia isolates were non-detectable by culture following 24 h incubation, including the non-selective enrichment samples. In the Atlantic Ocean brine, over a 1 month period, mean P. aeruginosa counts decreased by only 0.25 log10 units and mean B. cenocepacia counts decreased by approximately 4 log10 units (10,000 cfu/ml). This study demonstrated that Dead Sea brine exerted a lethal effect within 24 h on planktonic P. aeruginosa and B. cenocepacia. Thus, the Dead Sea effectively purges these organisms from its environment on a daily basis.

Phylogenetic profiles of in-house microflora in drains at a food production facility: comparison and biocontrol implications of Listeria-positive and -negative bacterial populations.

Listeria species experience complex interactions with other microorganisms, which may promote growth and colonization of the organism in local environments or negatively affect them. This study investigated the microbial community at a food production facility, examining interactions between Listeria and the associated microbiome. Listeria species can be transferred between zones in the production environment by individuals or equipment, and drains may act as a reservoir for the organism, reflecting the microbial flora potentially in the production environment. Drains that were colonized by Listeria species and those determined to be free of Listeria were examined. In each case, 16S rRNA gene analysis was performed using the PhyloChip platform. Some general similarities in bacterial population structure were observed when Listeria-negative and -positive drain communities were compared, with some distinct differences also noted. These included increased populations of the genera Prevotella and Janthinobacterium associated with the absence of Listeria species, whereas Enterococcus and Rhodococcus were in higher abundance in drains colonized by Listeria species. Based on these results, a selection of bacterial species were grown in coculture biofilm with a Listeria monocytogenes strain identified as having colonized a drain at the facility. Mixed-species biofilm experiments showed that Janthinobacterium inhibited attachment and subsequent biofilm formation of L. monocytogenes; however, Enterococcus gallinarum significantly increased it. The results of this study suggest the microbial community in food processing facilities can impact the colonization of Listeria species and that influencing the microbiome in favor of antilisterial species may reduce the colonization of Listeria species and limit the likelihood of product/process contamination.

Molecular characterization of skin microbiota between cancer cachexia patients and healthy volunteers.

Systemic inflammation contributes to both the development of cancer and of cachexia. The microenvironment of bacterial habitats might be changed during the progression of cancer cachexia. The aim of this study was to quantitatively and qualitatively compare the composition of the skin microbiota between cancer cachexia patients and healthy volunteers. Cutaneous bacteria were swabbed at the axillary fossa of 70 cancer cachexia patients and 34 healthy individuals from China. Nested-PCR-denaturing gradient gel electrophoresis (PCR-DGGE) with primers specifically targeting V3 region and quantitative PCR (qPCR) for total bacteria, Corynebacterium spp., Staphylococcus spp., and Staphylococcus epidermidis were performed on all samples. Barcoded 454 pyrosequencing of the V3-V4 regions was performed on 30 randomly selected samples. By comparing diversity and richness indices, we found that the skin microbiome of cachectic cancer patients is less diverse than that of healthy participants, though these differences were not significant. The main microbes that reside on human skin were divided into four phyla: Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes. Staphylococcus spp. and Corynebacterium spp. were the dominant bacteria at the genus level. Significantly fewer Corynebacterium spp. had been observed in cachexia patients compared to healthy subjects. These results suggest that the presence of cancer and cachexia alters human skin bacterial communities. Understanding the changes in microbiota during cancer cachexia may lead to new insights into the syndrome.

High diversity of bacterial pathogens and antibiotic resistance in salmonid fish farm pond water as determined by molecular identification employing 16S rDNA PCR, gene sequencing and total antibiotic susceptibility techniques.

The aim of this study was to examine the microbiological and related parameters (antibiotic resistance and pathogen identification) of water at two salmonid fish farms in Northern Ireland. Total Bacterial Counts at the Movanagher Fish Farm was 1730 colony forming units (cfu)/ml water (log10 3.24cfu/ml) and 3260cfu/ml (log10 3.51cfu/ml) at the Bushmills Salmon Station. Examination of resulting organisms revealed 10 morphological phenotypes, which were subsequently sequenced to determine their identification. All these organisms were Gram-negative and no Gram-positive organisms were isolated from any water sample. From these phenotypes, eight different genera were identified including Acinetobacter, Aeromonas, Chryseobacterium, Erwinia, Flavobacterium, Pseudomonas and Rheinheimera. One unnamed novel taxon was identified from water at the Movanagher Fish Farm, belonging to the genus Acinetobacter and has been tentatively named Acinetobacter movanagherensis. No other novel taxa were observed. All but one of these environmental organisms (Erwinia) are potential pathogens of fish disease. Total antibiotic resistance was observed to varying degrees in water specimens. The most resistant populations were observed in water taken from the Bushmills Salmon Station inlet, followed by water from the Movanagher Fish Farm. No resistance was observed against tetracycline and there was only one occurrence of resistance against ciprofloxacin. Overall, this study indicates that potential fish pathogens made up the majority of environmental organisms identified, even in the absence of recorded fish disease. There was also relatively high levels of total antibiotic resistance in the bacterial water populations examined, where tetracycline was the only antibiotic with zero resistance. These data indicate that the threat of bacterial disease is relatively close due to the indigenous colonization of farm water and that husbandry standards should be maintained at a high standard to avert bacterial disease outbreaks, rather than relying on the absence of specific pathogens in the immediate farm environment.

Improving health literacy of passengers of cruise ships: readability of passenger-facing COVID-19 information provided by commercial cruise lines-an infodemiology study.

Readability of COVID-19 information from 35 cruise lines was examined. Mean Flesch Reading Ease and Flesch-Kincaid Grade Level scores (±standard error of mean) were 46.6 ± 1.3 (target ≥60) and 10.9 ± 0.3 (target ≤ 8.0), respectively. Two (6%) cruise lines met readability reference targets. Readability tools may aid in preparing more easily read passenger-facing health-related information on existing infections, including COVID-19, other respiratory infections, as well as gastroenteritis (e.g. norovirus), as well as providing a methodology for improving the readability of information prepared for newly emerging infectious diseases.

Attitudes to cross infection, nebuliser hygiene and antimicrobial resistance in people with cystic fibrosis: Results of an international survey.

BACKGROUND: Respiratory infection is a major cause of disease severity in people with cystic fibrosis (PwCF). This project aimed to establish the CF community's opinion regarding cross infection (CI), nebuliser hygiene, antimicrobial resistance, personal impact of microbiological findings and the role of the microbiology laboratory. METHODS: A questionnaire was completed anonymously (n = 280; PwCF (n = 128), parents (n = 123); friends/family/carers/charity personnel (n = 29)) from 13 countries. Readability scores (Flesch Reading Ease (FRE), Flesch Kincaid Grade Level (FKGL)) were determined for CI/IP&C information from six national CF charities and 21 scientific abstracts. RESULTS: Respondents (72.5%) indicated knowledge of laboratory aspects of CF microbiology was important, however implications of microbiological findings on personal health/well-being were of higher importance (p < 0.0001). Cross infection/infection prevention & control (CI/IP&C) was of highest importance (95.6% respondents) with 27.3% indicating they were not given adequate information, particularly in older respondents (50 y+) (p = 0.006) versus young adults (16-29 y) and respondents from the Middle East versus N. America (p = 0.022) and Europe (p = 0.045). Responses highlighted how CI/IP&C health literacy could be enhanced. Respondents (77.3%), particularly females (p < 0.0001), indicated they would increase the frequency of nebuliser disinfection following guidance on infection risks/best practice, therefore an educational video was prepared. CI/IP&C readability scores (mean ± sd) from CF charities (FRE 52.5 ± 10.8; FKGL 9.7 ± 2.3) were more readable (p < 0.0001) than scientific abstracts (FRE 13.3 ± 11.1; FKGL 16.9 ± 2.3), however not meeting the targets (FRE≥60 and FKGL≤8). CONCLUSION: There is a requirement for further CI/IP&C evidence-based guidance, policies/guidelines, education awareness, best practice in the home environment and multi-modal communication, enabling the CF community to make informed choices on lifestyle behaviours.
