ABSTRACT

Within cystic fibrosis microbiology, there is often mismatch between the antibiotic susceptibility result of an isolated bacterial pathogen and the clinical outcome, when the patient is treated with the same antibiotic. The reasoning for this remains largely elusive. Antibiotic susceptibility to four antibiotics (ceftazidime, meropenem, minocycline and trimethoprim-sulfamethoxazole) was determined in consecutive isolates (n = 11) from an adult cystic fibrosis patient, over a 63 month period. Each isolate displayed its own unique resistotype. The first isolate was sensitive to all four antibiotics, in accordance with Clinical and Laboratory Standards Institute methodology and interpretative criteria. Resistance was first detected at four months, showing resistance to ceftazidime and meropenen and intermediate resistance to minocycline and trimethoprim-sulfamethoxazole. Pan resistance was first detected at 18 months (resistotype IV), with three resistotypes (I, II and III) preceding this complete resistotype. The bacterium continued to display further antibiotic susceptibility heterogeneity for the next 45 months, with the description of an additional seven resistotypes (resistotypes V-XI). The Relative Resistance Index of this bacterium over the 63 month period showed no relationship between the development of antibiotic resistance and time. Adoption of mathematical modelling employing multinomial distribution demonstrated that large numbers of individual colony picks (>40/sputum), would be required to be 78% confident of capturing all 11 resistotypes present. Such a requirement for large numbers of colony picks combined with antibiotic susceptibility-related methodological problems creates a conundrum in biomedical science practice, in providing a robust assay that will capture antibiotic susceptibility variation, be pragmatic and cost-effective to deliver as a pathology service, but have the reliability to help clinicians select appropriate antibiotics for their patients. This study represents an advance in biomedical science as it demonstrates potential variability in antibiotic susceptibility testing with Burkholderia cenocepacia. Respiratory physicians and paediatricians need to be made aware of such variation by biomedical scientists at the bench, so that clinicians can contextualise the significance of the reported susceptibility result, when selecting appropriate antibiotics for their cystic fibrosis patient. Furthermore, consideration needs to be given in providing additional guidance on the laboratory report to highlight this heterogeneity to emphasise the potential for misalignment between susceptibility result and clinical outcome.

ABSTRACT

OBJECTIVES: To estimate the carriage of Neisseira meningitidis (meningococci) in expectorated sputum from people with cystic fibrosis (CF) and to evaluate potential ramifications of such carriage for the health and (NM) wellbeing of physiotherapists performing airway clearance techniques. DESIGN: Descriptive observational study. MAIN OUTCOME MEASURES: Meningococcal carriage rate, CFTR mutation type and time to first meningococcal culture were determined. RESULTS: Microbiological data was examined from 100 patients from birth to present (31/12/2021), equating to 2455 patient years. NM was isolated from 6/100 (6%) adult CF patients who had F508del/F508del (homozygous), F508del/other (heterozygous) and other mutations. The median and mean time to first isolation of NM was 213 months and 230 months (standard deviation = 27.6 months), respectively, shortest time was 209 months, longest time 278 months. CONCLUSIONS: Physiotherapists should be aware of the risks to themselves of acquiring Neisseria meningtidis from CF patients' respiratory aerosols, whilst performing airway clearance techniques. Physiotherapists with underlying medical conditions or with specific concerns about meningococcal disease should discuss their circumstances with their occupational health team, to ensure optimal protection.

ABSTRACT

BACKGROUND AND PURPOSE: Rehabilitation professionals use subjective and objective outcome measures to assess stroke-related impact and impairment. Understanding if subjective and objective findings correlate among stroke survivors, especially if these associations differ between females and males, can inform care decisions. METHODS: A retrospective cross-sectional design was used, with data selected from subacute to chronic stroke survivors on age, time since stroke, the hand domain from the Stroke Impact Scale version 3.0 (SIS-H), and the Fugl-Meyer Upper Extremity (FMUE) Assessment. Group differences were assessed for all outcomes based on sex and time poststroke. Separate correlations for females and males were performed between the subjective (SIS-H) and objective measures (FMUE) of upper limb function and impairment. RESULTS: Data from 148 participants (44 females) were included in this study. SIS-H was significantly correlated with FMUE in both females and males ( P s ≤ 0.001). No significant differences were found between the groups' mean SIS-H or FMUE scores based on sex or time poststroke. DISCUSSION AND CONCLUSIONS: Subjective and objective measures of physical functioning were correlated in both females and males. Although we found no sex differences in our primary outcomes, the sample size of females was disproportionately lower than the males. This is consistent with an ongoing problem in the stroke recovery research field, where females are often underrepresented and understudied, and where females who experience higher levels of impairment are less likely to participate in research.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

While capacity for motor skill acquisition changes with healthy aging, there has been little consideration of how age-related changes in brain function or baseline brain structure support motor skill acquisition. We examined: (1) age-dependent changes in functional reorganization related to frontoparietal regions during motor skill acquisition, and (2) whether capacity for motor skill acquisition relates to baseline white matter microstructure in frontoparietal tracts. Healthy older and younger adults engaged in 4 weeks of skilled motor practice. Resting-state functional connectivity (rsFC) assessed functional reorganization before and after practice. Diffusion tensor imaging indexed microstructure of a frontoparietal tract at baseline, generated by rsFC seeds. Motor skill acquisition was associated with decreases in rsFC in healthy older adults and increases in rsFC in healthy younger adults. Frontoparietal tract microstructure was lower in healthy older versus younger adults, yet it was negatively associated with rate of skill acquisition regardless of group. Findings indicate that age-dependent alterations in frontoparietal function and baseline structure of a frontoparietal tract reflect capacity for motor skill acquisition.

ABSTRACT

Background: Antibiotic adherence is poor amongst people with cystic fibrosis (CF). Low-quality patient information leaflets (PILs), which accompany prescription antibiotics, with poor readability may contribute to poor antibiotic adherence, with the potential for antimicrobial resistance (AMR) development. The aim of this study was to examine the readability of antibiotic PILs used to treat CF lung infections. Methods: CF-related antibiotics (n = 23; seven classes: aminoglycosides, ß-lactams, fluoroquinolones, macrolides/lincosamides, oxazolidinones, tetracyclines, trimethoprim/sulfamethoxazole) were investigated. Readability of PILs (n = 141; 23 antibiotics) from the EU (n = 40), USA (n = 42) and UK (n = 59) was calculated. Results: Mean [± standard error of mean (SEM)] values for the Flesch Reading Ease (FRE) for EU, USA and UK were 50.0 ±â€Š1.1, 56.2 ±â€Š1.3 and 51.7 ±â€Š1.1, respectively (FRE target ≥60). Mean (± SEM) values for the Flesch Kinkaid Grade Level (FKGL) for the EU, USA and UK were 9.0 ±â€Š0.2, 7.5 ±â€Š0.2 and 9.6 ±â€Š0.2, respectively (FKGL target ≤8). US PILs were significantly shorter (P < 0.0001) in words (mean ±â€ŠSEM = 1365 ±â€Š52), than either UK or EU PILs, with fewer sentences (P < 0.0001), fewer words per sentence (P < 0.0001) and fewer syllables per word. The mean ( ±â€ŠSEM) reading time of UK PILs (n = 59) was 12.7 ±â€Š0.55 mins . Conclusions: Readability of antibiotic PILs is poor. Improving PIL readability may lead to improved health literacy, which may translate to increased antibiotic adherence and AMR avoidance. Authors preparing written materials for the lay/patient CF community are encouraged to employ readability calculators, so that final materials are within recommended readability reference parameters, to support the health (antibiotic) literacy of their readers.

ABSTRACT

Altered somatosensory function is common among stroke survivors, yet is often poorly characterized. Methods of profiling somatosensation that illustrate the variability in impairment within and across different modalities remain limited. We aimed to characterize post-stroke somatosensation profiles ("fingerprints") of the upper limb using an unsupervised machine learning cluster analysis to capture hidden relationships between measures of touch, proprioception, and haptic object recognition. Raw data were pooled from six studies where multiple quantitative measures of upper limb somatosensation were collected from stroke survivors (n = 207) using the Tactile Discrimination Test (TDT), Wrist Position Sense Test (WPST) and functional Tactile Object Recognition Test (fTORT) on the contralesional and ipsilesional upper limbs. The Growing Self Organizing Map (GSOM) unsupervised machine learning algorithm was used to generate a topology-preserving two-dimensional mapping of the pooled data and then separate it into clusters. Signature profiles of somatosensory impairment across two modalities (TDT and WPST; n = 203) and three modalities (TDT, WPST, and fTORT; n = 141) were characterized for both hands. Distinct impairment subgroups were identified. The influence of background and clinical variables was also modelled. The study provided evidence of the utility of unsupervised cluster analysis that can profile stroke survivor signatures of somatosensory impairment, which may inform improved diagnosis and characterization of impairment patterns.

ABSTRACT

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.

ABSTRACT

After stroke, impaired motor performance is linked to an increased demand for cognitive resources. Aerobic exercise improves cognitive function in neurologically intact populations and may be effective in altering cognitive function post-stroke. We sought to determine if high-intensity aerobic exercise paired with motor training in individuals with chronic stroke alters cognitive-motor function and functional connectivity between the dorsolateral prefrontal cortex (DLPFC), a key region for cognitive-motor processes, and the sensorimotor network. Twenty-five participants with chronic stroke were randomly assigned to exercise (n = 14; 66 ± 11 years; 4 females), or control (n = 11; 68 ± 8 years; 2 females) groups. Both groups performed 5-days of paretic upper limb motor training after either high-intensity aerobic exercise (3 intervals of 3 min each, total exercise duration of 23-min) or watching a documentary (control). Resting-state fMRI, and trail making test part A (TMT-A) and B were recorded pre- and post-intervention. Both groups showed implicit motor sequence learning (p < 0.001); there was no added benefit of exercise for implicit motor sequence learning (p = 0.738). The exercise group experienced greater overall cognitive-motor improvements measured with the TMT-A. Regardless of group, the changes in task score, and dwell time during TMT-A were correlated with a decrease in DLPFC-sensorimotor network functional connectivity (task score: p = 0.025; dwell time: p = 0.043), which is thought to reflect a reduction in the cognitive demand and increased automaticity. Aerobic exercise may improve cognitive-motor processing speed post-stroke.

ABSTRACT

Antimicrobial resistance (AMR) has now emerged as a chronic public health problem globally, with the forecast of 10 million deaths per year globally by 2050. AMR occurs when viruses, bacteria, fungi and parasites do not respond to antimicrobial treatments in humans and animals, thus allowing the survival of the microorganism within the host. The prominent cause contributing to the current crisis remains to be the overuse and misuse of antimicrobials, particularly the inappropriate usage of antibiotics, increasing the global burden of antimicrobial resistance. The global consumption and usage of antibiotics are therefore closely monitored at all times. This review provides a current overview of the implications of strategies used by international governmental organisations, including the UN's 17 Sustainable Development Goals (SDGs), to address the problem of antibiotic resistance, as well as the "One Health Approach," a system incorporating a multidisciplinary effort to achieve the best possible health outcome by acknowledging the clear connections between humans, animals and their shared environment. The importance of public awareness and health literacy of lay audiences still needs to be further emphasised as part of global and local action plans. Antimicrobial resistance continues to be a major global public health dilemma of the 21st century. Already this topic is receiving substantial political input from the G7 countries and continues to be on the agenda of numerous political conferences. The consequences of failure to adequately address AMR are profound, with estimations of a return to the pre-antibiotic era, where everyday infections relating to childbirth, surgery and open fractured limbs could be potentially life-threatening. AMR itself represents a microcosm of factors, including social anthropology, civil unrest/war, diasporas, ethnic displacement, political systems, healthcare, economics, societal behaviour both at a population and individual level, health literacy, geoclimatic events, global travel and pharmaceutical innovation and investment, thus finding a solution that adequately addresses AMR and which helps stem further AMR emergence is complicated. Success will involve individuals, communities and nations all working together to ensure that the world continues to possess a sufficient armamentarium of effective antimicrobials that will sustain human and animal health, both now and in the future.

ABSTRACT

There is debate about how implicit and explicit processes interact in sensorimotor adaptation, implicating how error signals drive learning. Target error information is thought to primarily influence explicit processes, therefore manipulations to the veracity of this information should impact adaptation but not implicit recalibration (i.e. after-effects). Thirty participants across three groups initially adapted to rotated cursor feedback. Then we manipulated numeric target error through knowledge of results (KR) feedback, where groups practised with correct or incorrect (+/-15°) numeric KR. Participants adapted to erroneous KR, but only the KR + 15 group showed augmented implicit recalibration, evidenced by larger after-effects than before KR exposure. In the presence of sensory prediction errors, target errors modulated after-effects, suggesting an interaction between implicit and explicit processes.

ABSTRACT

Introduction: Scientific communication, particularly the dissemination of research findings to both the scientific community and the general public, are skills required of graduates embarking on post-graduate studies and employment within the biomedical sciences sector. The aims of this action research project were to i) co-design an online scientific communication and digital capabilities resource, constructively aligned to the learning objectives of a final year undergraduate investigative research project; ii) ensure resource flexibility for future adaptation by others iii) embed authentic scientific communication learning assessments, namely, the preparation of a lay summary and visual abstract and iv) promote students' awareness of developed digital capabilities and transferable skills through written reflection. Materials and Methods: Student engagement, self-efficacy, experiences and performance and staff perceptions (n = 15) were evaluated by a mixed methods approach. Qualitative data was gathered from focus sessions, free text responses within questionnaires and content analysis of students' written reflections (n = 104). Quantitative data from 5-point Likert responses within student questionnaires (n = 31) and analysis of student scientific and lay writing (n = 146) using the readability parameters Flesch-Kincaid Grade Level and Flesch Reading Ease were analysed using non-parametric statistical methods. Results: A learning resource was co-designed with students, staff, local, national and international contributors and valued by both students and staff, enabling students to prepare scientific communication outputs of a professional standard by application of digital, analytical and scientific communication skills. Students prepared lay summaries which were statistically (p < 0.0001) more readable than their paired scientific abstracts. Significant correlations between easier readability of lay summaries and awarded marks for the written elements of the module were noted. Students reported their digital and communication capabilities increased significantly (p < 0.0001) throughout, from limited to good/excellent and reflected on the numerous transferable skills developed during preparation of assessments, with 75% reflecting on their digital capabilities. Discussion: Undergraduate students developed, appreciated and used varied scientific communication and digital skills to articulate research findings. The embedding of such activities throughout all levels of higher education will enable students to develop their digital and scientific skills and reflect on the development of such transferable skills for application in their future careers.

ABSTRACT

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a significant pathogen in people with cystic fibrosis (PwCF). There is a paucity of reports on MRSA infection dynamics within CF. It was the aim to examine the utility of Time-To-FirstIsolation (TTFI) metric and to correlate this with patient gender and CF transmembrane conductance regulator (CFTR) mutation type. METHODS: The microbiology of respiratory specimens from 100 adult (≥18 years) PwCF was examined (50 females; 50 males; mean age 24.6 years ±6.25 (SD)) from birth to present, equating to 2455 patient years. TTFI was determined in relation to (i) presence/absence of MRSA, (ii) CFTR mutation type and (iii) PwCF gender. RESULTS: MRSA was noted in 23% patients (10 female/13 males); (i) F508del/F508del homozygous (43.5%) and (ii) F508del/other heterozygous (56.5%). No non-F508del CFTR mutations types were noted. The median and mean TTFI was 137 months and 127.4 months respectively, shortest time was 23 months, longest time 211 months. There was no statistical significance in TTFI in relation to CFTR mutation group (p = 0.39) or gender (p = 0.71). CONCLUSIONS: TTFI is useful and applicable to the chronic infection model, where patients with a specific underlying disease are predisposed to acquire infections and where these infections are likely to become chronic. Intelligence offered by TTFI provides a window of opportunity to target IPC interventions, to help prevent MRSA acquisition. CF multidisciplinary teams, microbiologists and infection prevention specialists should utilise such TTFI data from their respective centres to help inform and plan intervention strategies to help prevent MRSA acquisition.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The avoidance of cross-infection remains of critical importance to prevent the transmission of cystic fibrosis (CF)-related microbial pathogens to persons/people with cystic fibrosis (PwCF). To date, there has been a paucity of infection prevention and control (IPC) guidance relating to infection risk at higher educational institutions. With improvements in treatments, more PwCF are now attending universities/colleges and educational institutions now seek CF-specific guidance on IPC from clinical CF teams/centres. METHODS: Real world infection-related questions from university students, educators, university support staff and the CF multidisciplinary team were received and collated from various stakeholders, including individual consultations and focus group sessions with two local universities. Subsequently, evidence-based recommendations were compiled from existing peer-reviewed literature and from cystic fibrosis organisations. Glossaries were constructed relating to clinical, microbiological and educational/pedagogical terminology to aid with the understanding amongst these stakeholder groups. RESULTS: This review addresses CF-related IPC recommendations across five areas of university/college life, including (i) on campus estate, (ii) teaching (lectures/tutorials/small study group work/group assignments), (iii) laboratory practicals, (iv) field trips/study visits/work placements and (v) residential accommodation and lists practical recommendations to help prevent the transmission of infections to PwCF students. CONCLUSIONS: It is important that the educational institutional environment is safe permitting the PwCF student to enjoy their educational experience and journey through higher education, culminating in achievement of their educational goals, employment and independent living. The guidance presented in this review is intended to equip educational establishments in creating their own bespoke and robust IPC policies relating to PwCF students.
