As the incidence of diabetic foot ulcers (DFU) increases, better treatments that improve healing should reduce complications of these ulcers including infections and amputations. We conducted a randomized controlled trial comparing outcomes between a novel purified reconstituted bilayer membrane (PRBM) to the standard of care (SOC) in the treatment of non-healing DFUs. This study included 105 patients who were randomized to either of two treatment groups (n = 54 PRBM; n = 51 SOC) in the intent to treat (ITT) group and 80 who completed the study per protocol (PP) (n = 47 PRBM; n = 33 SOC). The primary endpoint was the percentage of wounds closed after 12 weeks. Secondary outcomes included percent area reduction, time to healing, quality of life, and cost to closure. The DFUs that had been treated with PRBM healed at a higher rate than those treated with SOC (ITT: 83% vs. 45%, p = 0.00004, PP: 92% vs. 67%, p = 0.005). Wounds treated with PRBM also healed significantly faster than those treated with SOC with a mean of 42 versus 62 days for SOC (p = 0.00074) and achieved a mean wound area reduction within 12 weeks of 94% versus 51% for SOC (p = 0.0023). There were no adverse events or serious adverse events that were related to either the PRBM or the SOC. In comparison to the SOC, DFUs healed faster when treated with PRBM. Thus, the use of this PRBM is an effective option for the treatment of chronic DFUs.
To demonstrate how interoperable nursing care data can be used by nurses to create a more holistic understanding of the healthcare needs of multiple traumas patients with Impaired Physical Mobility. By proposing and validating linkages for the nursing diagnosis of Impaired Physical Mobility in multiple trauma patients by mapping to the Nursing Outcomes Classification (NOC) and Nursing Interventions Classification (NIC) equivalent terms using free-text nursing documentation.
A descriptive cross-sectional design, combining quantitative analysis of interoperable data sets and the Kappa's coefficient score with qualitative insights from cross-mapping methodology and nursing professionals' consensus.
Cross-mapping methodology was conducted in a Brazilian Level 1 Trauma Center using de-identified records of adult patients with a confirmed medical diagnosis of multiple traumas and Impaired Physical Mobility (a nursing diagnosis). The hospital nursing free-text records were mapped to NANDA-I, NIC, NOC and NNN linkages were identified. The data records were retrieved for admissions from September to October 2020 and involved medical and nursing records. Three expert nurses evaluated the cross-mapping and linkage results using a 4-point Likert-type scale and Kappa's coefficient.
The de-identified records of 44 patients were evaluated and then were mapped to three NOCs related to nurses care planning: (0001) Endurance; (0204) Immobility Consequences: Physiological, and (0208) Mobility and 13 interventions and 32 interrelated activities: (6486) Environmental Management: Safety; (0840) Positioning; (3200) Aspiration Precautions; (1400) Pain Management; (0940) Traction/Immobilization Care; (3540) Pressure Ulcer Prevention; (3584) Skincare: Topical Treatment; (1100) Nutrition Management; (3660) Wound Care; (1804) Self-Care Assistance: Toileting; (1801) Self-Care Assistance: Bathing/Hygiene; (4130) Fluid Monitoring; and (4200) Intravenous Therapy. The final version of the constructed NNN Linkages identified 37 NOCs and 41 NICs.
These valid NNN linkages for patients with multiple traumas can serve as a valuable resource that enables nurses, who face multiple time constraints, to make informed decisions efficiently. This approach of using evidence-based linkages like the one developed in this research holds high potential for improving patient's safety and outcomes.
In this study, there was no direct involvement of patients, service users, caregivers or public members in the design, conduct, analysis and interpretation of data or preparation of the manuscript. The study focused solely on analysing existing de-identified medical and nursing records to propose and validate linkages for nursing diagnoses.
El protomedicato fue una institución que veló por la salud de los vecinos que tenía carácter administrativo judicial y sus funciones principales fueron regularizar la labor de los que ejercieran cualquier tipo de atención sanitaria, otorgando licencias, fijando aranceles y vigilando el trabajo realizado en las boticas y la calidad de los medicamentos, a través de visitas periódicas. Pero, también, proponía medidas salubres e, incluso, disponía la movilización de personal médico a través del virreinato y participaba ante cualquier consulta de otras entidades coloniales, como el cabildo referentes a salud pública, como eliminación de acequias, declaración de pestes, y otros.
Effective health care relies on person-centeredness and teamwork, which are known to improve outcomes. These two concepts have been defined individually, but we could not find a definition of the combined concept. A preliminary definition was developed through a concept analysis; however, consensus on the concept has not been reached.
The aim of this study was to reach consensus on the definition and attributes of person-centered teamwork.
A consensus design allowed experts to collaborate and share their experience and wisdom to refine and reach consensus on the definition and attributes of person-centered teamwork. An e-Delphi was used to engage the experts.
Three rounds of online engagement with 12 experts were needed to reach consensus on the definition and attributes of person-centered teamwork. The attributes reached consensus of 82% after the first round. The definition had 82% consensus after the three rounds. The definition had been adjusted and refined according to the expert input. The newly adjusted definition was established.
We successfully used the e-Delphi method to obtain consensus on the attributes and definition of person-centered teamwork. The definition of person-centered teamwork can be further developed and included in clinical practice to guide improved clinical outcomes. The consensus definition of person-centered teamwork provides a clear understanding of the meaning thereof, which may in turn enrich the usability thereof in clinical practice. Person-centered teams improve outcomes for persons receiving care in hospitals. Building person-centered teams are now better understood and the foundation of building these teams defined. We engaged with 12 experts in the academic and clinical field of person-centeredness and teamwork. The use and value of the Delphi method to obtain consensus is now better understood and can assist future research development.
This Phase 1b study was designed to evaluate the safety and efficacy of pravibismane, a novel broad-spectrum topical anti-infective, in managing moderate or severe chronic diabetic foot ulcer (DFU) infections. This randomized, double-blind, placebo-controlled, multicenter study consisted of 39 individuals undergoing pravibismane treatment and 13 individuals in the placebo group. Assessment of safety parameters included clinical observations of tolerability and pharmacokinetics from whole blood samples. Pravibismane was well-tolerated and exhibited minimal systemic absorption, as confirmed by blood concentrations that were below the lower limit of quantitation (0.5 ng/mL) or in the low nanomolar range, which is orders of magnitude below the threshold of pharmacological relevance for pravibismane. Pravibismane treated subjects showed approximately 3-fold decrease in ulcer size compared to the placebo group (85% vs. 30%, p = 0.27). Furthermore, the incidence of ulcer-related lower limb amputations was approximately 6-fold lower (2.6%) in the pooled pravibismane group versus 15.4% in the placebo group (p = 0.15). There were no treatment emergent or serious adverse events related to study drug. The initial findings indicate that topical pravibismane was safe and potentially effective treatment for improving recovery from infected chronic ulcers by reducing ulcer size and facilitating wound healing in infected DFUs (ClinicalTrials.gov Identifier NCT02723539).
To describe the current state of the literature on nurses' and midwives' knowledge, perceptions and experiences of managing parental postnatal depression (PPND).
The Joanna Briggs Institute scoping review method and the PRISMA extension for Scoping Reviews guided the work.
A systematic search of PubMed, CINAHL, Embase, MEDLINE, PsycINFO and Scopus databases was conducted in January and February 2023.
Peer-reviewed primary research articles published in English between 2012 and 2023 that involved nurses or midwives managing PPND were included. Rayyan was used to screen titles, abstracts and full-text articles. A spreadsheet was used to organize extracted data and synthesize results.
Twenty-nine articles met the inclusion criteria. Most study samples were of mothers, and few were from middle- and lower-income countries. Nurses and midwives lacked knowledge about PPND, yet they felt responsible for its management. Nurses and midwives faced significant organizational and systems-level challenges in managing PPND. However, nurses and midwives facilitated PPND care in collaboration with other healthcare providers.
The review highlights significant gaps in the nurses' and midwives' care of PPND. Educational programmes are necessary to increase nurse and midwife knowledge of PPND and strategies for its management, including facilitating collaboration across the healthcare system and eliminating organizational and systemic-related barriers. Additional focused research is needed on nurses' and midwives' knowledge, perception of and experience with PPND beyond mothers, such as with fathers, sexually and gender-minoritized parents and surrogate mothers. Finally, additional research is needed in middle- and lower-income countries where nurses and midwives may face a higher burden of and unique cultural considerations in managing PPND.
PPND can affect the parent's mental and physical health and relationship with their child. If left untreated, PPND can lead to long-term consequences, including child developmental delays, behavioural problems and difficulties with parental–child attachment.

The aim of the study was to establish the feasibility of delivering a structured post-diagnosis information and support program to dyads (persons living with dementia or mild cognitive impairment and family carers) in two primary care settings.
A two-phase explanatory mixed-method approach guided by the Bowen Feasibility Framework focused on acceptability, implementation, adaptation, integration and efficacy of a five-part programme. In phase 1, the quantitative impact of the programme on the dyadic programme recipients' self-efficacy, quality of life, dyadic relationship and volume of care was measured. In phase 2, inductive content analysis focused on nurse and dyad participant experiences of the programme. Quantitative and qualitative data were reviewed to conclude each element of feasibility.
Four registered nurses working within the participating sites were recruited, trained as programme facilitators and supported to deliver the programme. Eligible dyads attending the respective primary health clinics were invited to participate in the programme and complete surveys at three time points: recruitment, post-programme and 3-month follow-up. Post-programme semi-structured interviews were conducted with dyads and programme facilitators.
Twenty-nine dyads completed the program; the majority were spousal dyads. The programme proved acceptable to the dyads with high retention and completion rates. Implementation and integration of the programme into usual practice were attributed to the motivation and capacity of the nurses as programme facilitators. Regarding programme efficacy, most dyads reported they were better prepared for the future and shared the plans they developed during the programme with family members.
Implementing a structured information and support programme is feasible, but sustainability requires further adaptation or increased staff resources to maintain programme fidelity. Future research should consider selecting efficacy measures sensitive to the unique needs of people living with dementia and increasing follow-up time to 6 months.
This study established the feasibility of registered nurses delivering a post-diagnosis information and support programme for people living with early-stage dementia or mild cognitive impairment and their informal carers in primary care settings. The motivation and capacity of nurses working as programme facilitators ensured the integration of the programme into usual work, but this was not considered sustainable over time. Family carer dyads reported tangible outcomes and gained confidence in sharing their diagnosis with family and friends and asking for assistance. Findings from this study can be used to provide direction for a clinical trial investigating the effectiveness of the structured information and support programme in the primary care setting.

A public hospital memory clinic and general medical practice participated in project design, study protocol development and supported implementation.
Smoking cessation in pregnancy remains a public health priority. Our team used the Behaviour Change Wheel to develop the Midwives and Obstetricians Helping Mothers to Quit smoking (MOHMQuit) intervention with health system, leader (including managers and educators) and clinician components. MOHMQuit addresses a critical evidence to practice gap in the provision of smoking cessation support in antenatal care. It involves nine maternity services in New South Wales in a cluster randomised stepped-wedge controlled trial of effectiveness. This paper describes the design and rationale for the process evaluation of MOHMQuit. The process evaluation aims to assess to what extent and how MOHMQuit is being implemented (acceptability; adoption/uptake; appropriateness; feasibility; fidelity; penetration and sustainability), and the context in which it is implemented, in order to support further refinement of MOHMQuit throughout the trial, and aid understanding and interpretation of the results of the trial.
The process evaluation is an integral part of the stepped-wedge trial. Its design is underpinned by implementation science frameworks and adopts a mixed methods approach. Quantitative evidence from participating leaders and clinicians in our study will be used to produce individual and site-level descriptive statistics. Qualitative evidence of leaders’ perceptions about the implementation will be collected using semistructured interviews and will be analysed descriptively within-site and thematically across the dataset. The process evaluation will also use publicly available data and observations from the research team implementing MOHMQuit, for example, training logs. These data will be synthesised to provide site-level as well as individual-level implementation outcomes.
The study received ethical approval from the Population Health Services Research Ethics Committee for NSW, Australia (Reference 2021/ETH00887). Results will be communicated via the study’s steering committee and will also be published in peer-reviewed journals and presented at conferences.

Violence against physicians in the workplace is a prevalent global issue, and Bangladesh is no exception. Such violence significantly disrupts healthcare delivery and the attainment of universal health coverage. This study aimed to comprehensively evaluate the prevalence, nature and associated risk factors of workplace violence (WPV) against physicians in Bangladesh.
This descriptive cross-sectional study was conducted at a public tertiary care hospital involving 441 physicians with a minimum tenure of 6 months. Data were gathered through a structured self-reported questionnaire, and statistical analyses were performed by using SPSS V.25.
Out of the surveyed physicians, 67.3% (n=297) reported experiencing violence, categorised as 84.5% psychological, 13.5% physical and 2% sexual in nature. Predominant forms of psychological violence included bullying (48.8%) and threats (40.1%). The mean age of exposed physicians was 32.5±4.3 (SD) years. Those working in the emergency unit (45.8%), surgery and allied departments (54.2%), engaging in rotating shift work (70%), morning shifts (59.6%) and postgraduate trainees (68%) were frequently subjected to violence. Factors significantly associated with WPV included placement in surgery and allied departments (p
A higher proportion of physicians at the early to mid-level stages of their careers, especially those in rotating shifts and surgery-related departments, reported incidence of WPV. Urgent intervention from policy-makers and healthcare entities is imperative to implement preventive measures. Strengthening security measures, establishing antiviolence policies and providing comprehensive training programmes are crucial steps towards ensuring a safer work environment for healthcare professionals.
The aim of the study was to develop recommendations for creating a healthy work environment based on current literature for nurses working within the US Military Health System (MHS). However, our findings would likely benefit other nursing populations and environments as well.
Systematic literature review.
We conducted a systematic literature search for articles published between January 2010 until January 2024 from five databases: PubMed, Joanna Briggs, Embase, CINAHL and Scopus.
Articles were screened, selected and extracted using Covidence software. Article findings were synthesized to create recommendations for the development, implementation and measurement of healthy work environments.
Ultimately, a total of 110 articles met the criteria for inclusion in this review. The articles informed 13 recommendations for creating a healthy work environment. The recommendations included ensuring teamwork, mentorship, job satisfaction, supportive leadership, nurse recognition and adequate staffing and resources. Additionally, we identified strategies for implementing and measuring these recommendations.
This thorough systematic review created actionable recommendations for the creation of a healthy work environment. Based on available evidence, implementation of these recommendations could improve nursing work environments.
This study identifies methods for implementing and measuring aspects of a healthy work environment. Nurse leaders or others can implement the recommendations provided here to develop healthy work environments in their hospitals, clinics or other facilities where nurses practice.

To assess agreement of pressure injury risk level and differences in preventative intervention prescription between nurses using a structured risk assessment tool compared with clinical judgement.
Interrater agreement study.
Data were collected from November 2019 to December 2022. Paired nurse-assessors were allocated randomly to independently assess pressure injury risk using a structured tool (incorporating the Waterlow Score), or clinical judgement; then prescribe preventative interventions. Assessments were conducted on 150 acute patient participants in a general tertiary hospital. Agreement of risk level was analysed using absolute agreement proportions, weighted kappa and prevalence-adjusted and bias-adjusted kappa.
Ninety-four nurse assessors participated. Absolute agreement of not-at-risk versus at-risk-any-level was substantial, but absolute agreement of risk-level was only fair. Clinical judgement assessors tended to underestimate risk. Where risk level was agreed, prescribed intervention frequencies were similar, although structured tool assessors prescribed more interventions mandated by standard care, while clinical judgement assessors prescribed more additional/optional interventions. Structured tool assessors prescribed more interventions targeted at lower-risk patients, whereas assessors using clinical judgement prescribed more interventions targeted at higher-risk patients.
There were clear differences in pressure injury risk-level assessment between nurses using the two methods, with important differences in intervention prescription frequencies found. Further research is required into the use of both structured tools and clinical judgement to assess pressure injury risk, with emphasis on the impact of risk assessments on subsequent preventative intervention implementation.
The results of this study are important for clinical practice as they demonstrate the influence of using a structured pressure injury risk assessment tool compared to clinical judgement. Whilst further research is required into the use of both structured tools and clinical judgement to assess pressure injury risk and prescribe interventions, our findings do not support a change in practice that would exclude the use of a structured pressure injury risk assessment tool.
This study adhered to the GRRAS reporting guideline.
No patient or public involvement in this study.
Educators and researchers can use the findings to guide teaching about pressure injury risk assessment and preventative intervention and to direct future studies. For clinical nurses and patients, a change in clinical practice that would exclude the use of a structured risk assessment tool is not recommended and further work is needed to validate the role of clinical judgement to assess risk and its impact on preventative intervention.
To explore youth, caregiver and staff perspectives on their vision of trauma-informed care, and to identify and understand potential considerations for the implementation of a trauma-informed care programme in an inpatient mental health unit within a paediatric hospital.
We applied the Interpretive Description approach, guided by complexity theory and the Implementation Roadmap, and used Applied Thematic Analysis methods.
Twenty-five individuals participated in individual or group interviews between March and June 2022, including 21 healthcare professionals, 3 youth and 1 caregiver. We identified two overarching themes. The first theme, ‘Understanding and addressing the underlying reasons for distress’, related to participants’ understanding and vision of TIC in the current setting comprising: (a) ‘Participants’ understanding of TIC’; (b) ‘Trauma screening and trauma processing within TIC’; (c) ‘Taking “a more individualized approach”’; (d) ‘Unit programming’; and (e) “Connecting to the community”. The second theme, ‘Factors that support or limit successful TIC implementation’ comprises: (a) ‘The need for a broad “cultural shift”’; (b) ‘The physical environment on the unit’; and (c) ‘Factors that may limit successful implementation’.
We identified five key domains to consider within trauma-informed care implementation: (a) the centrality of engagement with youth, caregivers and staff in trauma-informed care delivery and implementation, (b) trauma-informed care core programme components, (c) factors that may support or limit success in implementing trauma-informed care within the mental health unit and (d) hospital-wide and (e) the importance of intersectoral collaboration (partnering with external organizations and sectors).
When implementing TIC, there is an ongoing need to increase clarity regarding TIC interventions and implementation initiatives. Youth, caregiver and healthcare professional participants shared considerations important for planning the delivery and implementation of trauma-informed care in their setting. We identified five key domains to consider within trauma-informed care implementation: (a) the centrality of relational engagement, (b) trauma-informed care programme components, (c) factors that may support or limit successful implementation of trauma-informed care within the mental health unit and (d) hospital-wide and (e) the importance of intersectoral collaboration. Organizations wishing to implement trauma-informed care should consider ongoing engagement with all relevant knowledge user groups throughout the process.

This study explores the mediational role of resilience, experiential avoidance and emotion regulation in the levels of anxiety, depression and posttraumatic stress disorder (PTSD) of healthcare workers during the COVID-19 pandemic. Additionally, we explored the association of such levels with personal and professional variables.
Cross-sectional study.
Healthcare professionals working in Spain (N = 786) were recruited following a snowball approach in November and December 2021. Resilience, emotion regulation, experiential avoidance, depression, anxiety, PTSD and work-related variables were measured. Mean differences and correlations were computed, and a path analysis with latent variables (PALV) model was tested.
In total, 18.8% of the sample scored above the cut-off score for depression, 24.6% for anxiety and 36.4% for PTSD. Higher resilience and lower experiential avoidance and expression suppression were correlated with better mental health. The PALV model explained 42%–53% of mental health outcomes. Experiential avoidance showed the greatest explanatory power and mediated the impact that stressors had on mental health. Some work-related variables correlated with greater psychological impact. These factors encompassed being a nurse, feeling that their job remained stressful and had not yet returned to its pre-pandemic state and having interacted with individuals facing economic difficulties due to the pandemic, and those who had lost their lives to COVID-19.
Healthcare workers showed high levels of psychological impact during the COVID-19 pandemic. Such impact was predicted from some work-stress variables and the reliance on maladaptive strategies such as experiential avoidance and expressive suppression.
Training healthcare professionals to use coping strategies incompatible with experiential avoidance may improve their mental health. Additionally, better working conditions are fundamental for reducing the impact of critical situations on healthcare workers' mental health.

BackgroundPost-traumatic stress disorders (PTSD) is associated with worse asthma outcomes in individuals exposed to the World Trade Center (WTC) site.
Research questionDo WTC workers with coexisting PTSD and asthma have a specific inflammatory pattern that underlies the relationship with increased asthma morbidity?
Study design and methodsWe collected data on a cohort of WTC workers with asthma recruited from the WTC Health Program. Diagnosis of PTSD was ascertained with a Structured Clinical Interview for DSM-5 (Diagnostic and Statistical Manuel of Mental Disorders) and the severity of PTSD symptoms was assessed with the PTSD Checklist 5. We obtained blood and sputum samples to measure cytokines levels in study participants.
ResultsOf the 232 WTC workers with diagnosis of asthma in the study, 75 (32%) had PTSD. PTSD was significantly associated with worse asthma control (p = 0.002) and increased resource utilization (p = 0.0002). There was no significant association (p>0.05) between most blood or sputum cytokines with PTSD diagnosis or PCL-5 scores both in unadjusted and adjusted analyses.
InterpretationOur results suggest that PTSD is not associated with blood and sputum inflammatory markers in WTC workers with asthma. These findings suggest that other mechanisms likely explain the association between PTSD and asthma control in WTC exposed individuals.

ObjectiveIndividuals born very preterm ( Study design
Cohorts with data on physical activity and cognitive function in adults born very preterm/very low birth weight and term-born controls were recruited from the Research on European Children and Adults Born Preterm, and the Adults Born Preterm International Collaboration Consortia. A systematic literature search was performed in PubMed and Embase.
ResultsFive cohorts with 1644 participants aged 22–28 years (595 very preterm/very low birth weight and 1049 controls) were included. Adults born very preterm/very low birth weight reported 1.11 (95% CI: 0.68 to 1.54) hours less moderate to vigorous physical activity per week than controls, adjusted for cohort, age and sex. The difference between individuals born very preterm/very low birth weight and controls was larger among women than among men. Neither intelligence quotient nor self-reported executive function mediated the association between very preterm/very low birth weight and moderate to vigorous physical activity. Results were essentially the same when we excluded individuals with neurosensory impairments.
ConclusionAdults born very preterm/very low birth weight, especially women, reported less moderate to vigorous physical activity than their term-born peers. Cognitive function did not mediate this association. Considering the risk of adverse health outcomes among individuals born preterm, physical activity could be a target for intervention.

ContextPotentially inappropriate prescribing of medications in older adults, particular those with dementia, can lead to adverse drug events including falls and fractures, worsening cognitive impairment, emergency department visits, and hospitalizations. Educational mailings from health plans to patients and their providers to encourage deprescribing conversations may represent an effective, low-cost, “light touch”, approach to reducing the burden of potentially inappropriate prescription use in older adults with dementia.
ObjectivesThe objective of the Developing a PRogram to Educate and Sensitize Caregivers to Reduce the Inappropriate Prescription Burden in Elderly with Alzheimer’s Disease (D-PRESCRIBE-AD) trial is to evaluate the effect of a health plan based multi-faceted educational outreach intervention to community dwelling patients with dementia who are currently prescribed sedative/hypnotics, antipsychotics, or strong anticholinergics.
MethodsThe D-PRESCRIBE-AD is an open-label pragmatic, prospective randomized controlled trial (RCT) comparing three arms: 1) educational mailing to both the health plan patient and their prescribing physician (patient plus physician arm, n = 4814); 2) educational mailing to prescribing physician only (physician only arm, n = 4814); and 3) usual care (n = 4814) among patients with dementia enrolled in two large United States based health plans. The primary outcome is the absence of any dispensing of the targeted potentially inappropriate prescription during the 6-month study observation period after a 3-month black out period following the mailing. Secondary outcomes include dose-reduction, polypharmacy, healthcare utilization, mortality and therapeutic switching within targeted drug classes.
ConclusionThis large pragmatic RCT will contribute to the evidence base on promoting deprescribing of potentially inappropriate medications among older adults with dementia. If successful, such light touch, inexpensive and highly scalable interventions have the potential to reduce the burden of potentially inappropriate prescribing for patients with dementia.ClinicalTrials.gov Identifier: NCT05147428.

BackgroundFebrile jaundice is a common indicator of certain infectious diseases, including hepatitis E. In Cameroon, the yellow fever virus is the only pathogen that is monitored in patients who present with this symptom. However, more than 90% of the samples received as part of this surveillance are negative for yellow fever. This study aimed to describe the prevalence and hepatitis E virus (HEV) genotype among yellow fever-negative patients in the Far North and West regions of Cameroon.
MethodsIn a cross-sectional study, yellow fever surveillance-negative samples collected between January 2021 and January 2023 were retrospectively analyzed. Anti-HEV IgM and IgG antibodies were tested using commercially available ELISA kits. Anti-HEV IgM and/or IgG positive samples were tested for HEV RNA by real-time RT-PCR, followed by nested RT-PCR, sequencing and phylogenetic analysis.
ResultsOverall, 121 of the 543 samples (22.3%, 95% CI: 19.0% - 26.0%) were positive for at least one anti-HEV marker. Amongst these, 8.1% (44/543) were positive for anti-HEV IgM, 5.9% (32/543) for anti-HEV IgG, and 8.3% (45/544) for both markers. A total of 15.2% (12/79) samples were positive for HEV RNA real-time RT-PCR and 8 samples were positive for HEV RNA by nested RT-PCR. Phylogenetic analysis showed that the retrieved sequences clustered within HEV genotypes/subtypes 1/1e, 3/3f and 4/4b.
ConclusionOur results showed that HEV is one of the causes of acute febrile jaundice in patients enrolled in the yellow fever surveillance program in two regions of Cameroon. We described the circulation of three HEV genotypes, including two zoonotic genotypes. Further studies will be important to elucidate the transmission routes of these zoonotic HEV genotypes to humans in Cameroon.

BackgroundMicrobial biofilms, as a hallmark of cystic fibrosis (CF) lung disease and other chronic infections, remain a desirable target for antimicrobial therapy. These biopolymer-based viscoelastic structures protect pathogenic organisms from immune responses and antibiotics. Consequently, treatments directed at disrupting biofilms represent a promising strategy for combating biofilm-associated infections. In CF patients, the viscoelasticity of biofilms is determined mainly by their polymicrobial nature and species-specific traits, such as Pseudomonas aeruginosa filamentous (Pf) bacteriophages. Therefore, we examined the impact of microbicidal ceragenins (CSAs) supported by mucolytic agents–DNase I and poly-aspartic acid (pASP), on the viability and viscoelasticity of mono- and bispecies biofilms formed by Pf-positive and Pf-negative P. aeruginosa strains co-cultured with Staphylococcus aureus or Candida albicans.
MethodsThe in vitro antimicrobial activity of ceragenins against P. aeruginosa in mono- and dual-species cultures was assessed by determining minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC/MFC). Inhibition of P. aeruginosa mono- and dual-species biofilms formation by ceragenins alone and in combination with DNase I or poly-aspartic acid (pASP) was estimated by the crystal violet assay. Additionally, the viability of the biofilms was measured by colony-forming unit (CFU) counting. Finally, the biofilms’ viscoelastic properties characterized by shear storage (G’) and loss moduli (G”), were analyzed with a rotational rheometer.
ResultsOur results demonstrated that ceragenin CSA-13 inhibits biofilm formation and increases its fluidity regardless of the Pf-profile and species composition; however, the Pf-positive biofilms are characterized by elevated viscosity and elasticity parameters.
ConclusionDue to its microbicidal and viscoelasticity-modifying properties, CSA-13 displays therapeutic potential in biofilm-associated infections, especially when combined with mucolytic agents.
