Pathogenic bacterial species and the microbiome of cat fleas (<i>Ctenocephalides felis</i>) inhabiting flea-infested homes

by Taylor E. Gin, Charlotte O. Moore, Trey Tomlinson, Grace Wilson, Amiah Gray, Cameron Sutherland, Kamilyah Miller, Krista Li, Michael Canfield, Brian Herrin, Erin Lashnits, Benjamin Callahan

Background

Ctenocephalides felis is a common ectoparasite of dogs and cats and can transmit a variety of pathogens including Bartonella and Rickettsia species. These bacteria, along with the known endosymbiont Wolbachia, are well-documented members of the C. felis microbiome, but species-level information is limited. Additionally, little is known about the variation in the C. felis microbiome in fleas from different sources and when different sequencing methods are applied to the same samples.

Objective

This study aimed to characterize the flea microbiome using both short-read (V3/V4) and long-read (full-length) 16S rRNA gene sequencing, determine whether long-read sequencing improves species-level identification especially in known pathogenic genera, and evaluate differences in microbial composition between fleas collected from cats, dogs, and environmental traps.

Methods

Fleas were collected from cats, dogs, and traps in flea-infested homes in Florida, pooled by source, and sequenced using short- (V3/V4) and long-read (full-length) 16S rRNA gene sequencing. Microbial prevalence and abundance were compared across sequencing approaches. Community composition was evaluated for differences between sources and houses. Candidate members of the flea microbiome were identified based on a combination of prevalence, abundance, and statistical signatures of potential contaminant origin. For Rickettsia and Bartonella, species-level taxonomic assignments were refined using a phylogenetic approach.

Results

Wolbachia, Rickettsia, and Bartonella were the most prevalent and abundant taxa. Spiroplasma was identified as a fourth core member of the flea microbiome. Long-read sequencing enabled better, but not perfect, species-level classification of Bartonella and Rickettsia compared to short-read sequencing. Important relationships between specific ASVs and flea sources were identified, for example fleas from cats harbored higher abundances of B. clarridgeiae and B. henselae than fleas from traps.

Objectives

South Asian populations in the UK experience increased health risks related to long-term conditions, exacerbated by underdiagnosis, cultural differences in help-seeking behaviours, language barriers, low health literacy and a lack of culturally sensitive services. We know that group interventions that include education and rehabilitation, such as cardiac and pulmonary rehabilitation, are highly effective, but people from diverse communities often face barriers to access and engage with them. This review aims to synthesise evidence on the barriers and facilitators to education and rehabilitation interventions experienced by South Asian people living with long-term conditions.

Design

A systematic review of qualitative studies using meta-ethnography as the analytical approach to synthesis was conducted, following Noblit and Hare’s approach, eMERGe Reporting Guidance for Meta-Ethnography, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Systematic searches were performed across MEDLINE, PsycINFO, CINAHL, CENTRAL, EMBASE and Applied Social Sciences Index and Abstracts from database inception through March 2024 (updated April 2025).

Data sources

MEDLINE (Ovid), PsycINFO (Ovid), CINAHL (EBSCOhost platform), CENTRAL (Cochrane Library), EMBASE (Ovid), Applied Social Sciences Index and Abstracts (ProQuest platform) were searched from inception to March 2024 (updated April 2025).

Eligibility criteria

We included qualitative research exploring the attitudes, views and experiences of South Asian adults (outside of South Asia) with diabetes, cardiovascular disease or chronic obstructive pulmonary disease (COPD) regarding group treatments for these conditions.

Data extraction and synthesis

Two independent reviewers searched, screened and coded studies, while remaining authors peer-reviewed. Study quality was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. Data extraction and synthesis followed eMERGe and PRISMA reporting guidance, with findings synthesised qualitatively.

Results

Of 8348 identified citations, 17 studies met inclusion criteria, providing data from South Asian people living with cardiovascular disease and diabetes mellitus. No studies including people with COPD met the inclusion criteria. Synthesis revealed four overarching themes, each incorporating both barriers and facilitators: faith, culture, communication, and safe space and professional relationship.

Conclusions

Findings indicate that current group education and rehabilitation interventions are not fully inclusive of South Asian needs, often lacking cultural sensitivity, which impedes engagement. Special attention is required for South Asian women, who can face additional cultural and societal barriers. Addressing these challenges through culturally sensitive care, such as flexible intervention scheduling around religious practices, gender-sensitive adaptations and culturally tailored communication strategies, has potential to improve engagement in education and rehabilitation interventions, and therefore long-term condition outcomes.

Por: Miah · J. · Bee · P. E. · Lunat · F. · McPhillips · R. · Taylor · A. K. · Aseem · S. · Sharma · D. · Husain · N. · Chew-Graham · C.
Objectives

To explore the views and perspectives of British South Asian (BSA) women and Positive Health Programme (PHP) facilitators on the usefulness and experiences of the PHP intervention for managing postnatal depression (PND) in primary care settings.

Design

Qualitative study with semi-structured interviews to explore perceptions of acceptability and implementation. A patient and public involvement group provided their insights and feedback on study topic guides, analysis and outcomes.

Setting and participants

We sampled trial participants from the PHP intervention database to ensure variation in geographic setting, age, socioeconomic status and ethnicity. PHP facilitators involved in the trial were also invited to participate in an interview.

Interviews with study participants were conducted at participants’ homes, and community centres, or via phone. Interviews with PHP facilitators were conducted via phone or online. Interview recordings were transcribed verbatim and analysed using thematic analysis and subsequently the Theoretical Framework of Acceptability (TFA) was applied. Recruitment took place between February 2017 and March 2020.

Results

Thirty interviews were conducted—19 trial participants and 11 PHP facilitators. The PHP intervention was viewed positively, with appreciation of its therapeutic content and components such as childcare and refreshments that facilitated engagement. Participants reported improved confidence and well-being and supported their needs. Participants understood the intervention’s purpose. Both intervention participants and facilitators noted strengthened self-efficacy.

Some participants experienced difficulties balancing childcare and attendance, implying a need for logistical assistance. Stigma about mental health in the BSA community was viewed as persistent, recommending future programmes efforts on strategies to reduce stigma and develop supportive environment.

Conclusion

This study demonstrates the possibility of PHP intervention being integrated into routine care by providing culturally tailored support for BSA women with PND, primarily through family engagement and facilitator support. Future research on scalability, alongside community engagement efforts, will strengthen its acceptability and broader applicability.

Introduction

Cervical cancer (CaCx) is a leading cause of cancer-related deaths among women in South Africa, often presenting at advanced stages and requiring chemoradiotherapy. In South Africa, the burden is disproportionately high among women living with HIV, with limited access to radiotherapy further compounding treatment challenges. Despite this documented disparity, limited data exist on patients in a South African context. This protocol describes the research methodology to assess patterns of care, treatment delays, interruptions and survival outcomes in patients with advanced CaCx, addressing an urgent need for local data in low-income and middle-income countries to provide evidence-based improvements in care.

Methods and analysis

The Cervical Cancer Cohort at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH-CCC), initiated in 2023, is a mixed retrospective and prospective single-centre study investigating the characteristics, challenges and outcomes of patients with advanced CaCx. It includes women aged ≥18 years with a histopathological diagnosis of stage IB3–IVA CaCx treated at CMJAH Radiation Oncology. The retrospective component covers data from September 2018 to August 2023. Data collection is complete and the team is currently conducting quality control. The prospective component began in October 2023 and aims to enrol participants over 2 years, with follow-up for up to 3 years. The study is ongoing, and an extension for continued enrolment beyond September 2025 is being sought. Participants provide baseline data on demographics, socioeconomic status, cultural influences and healthcare access, with updates every 3 months. When necessary, the next of kin provides follow-up information. The study aims to inform strategies to improve outcomes and reduce the CaCx burden in South Africa.

Ethics and dissemination

Ethics approval for this study was obtained from the Human Research Ethics Committee (Medical) at the University of the Witwatersrand in Johannesburg, South Africa, with an ethical clearance certificate (MM221001 MED22-09-085). The results will be widely distributed through presentations at national and international conferences and published in peer-reviewed open-access journals, ensuring wide access to the results.

Negative Pressure Wound Therapy Use: Recommendations and Insights From a Middle Eastern Panel of Experts

ABSTRACT

The number of patients requiring wound care is increasing, placing a burden on healthcare institutions and clinicians. While negative pressure wound therapy (NPWT) use has become increasingly common, Middle East-specific wound care guidelines are limited. An in-person meeting was held in Dubai with 15 wound care experts to develop guidelines for NPWT and NPWT with instillation and dwell (NPWTi-d) use for the Middle East. A literature search was performed using PubMed, Science Direct and Cochrane Reviews. Prior to the meeting, panel members reviewed literature and existing guidelines on NPWT and/or NPWTi-d use. A wound management treatment algorithm was created. Patient and wound assessment at presentation and throughout the treatment plan was recommended. Primary closure was recommended for simple wounds, and NPWT use was suggested for complex wounds requiring wound bed preparation. NPWTi-d use was advised when wound cleansing is required, if the patient is unsuitable for surgical debridement, or if surgical debridement is delayed. When NPWTi-d is unavailable, panel members recommended NPWT. Panel members recommended NPWT for wound bed preparation and NPWTi-d when wound cleansing is needed. These recommendations provide general guidance for NPWT and NPWTi-d use and should be updated as more clinical evidence becomes available.

Poorer Nurse Staffing in Black-Serving Hospitals

imageBackground Patients in hospitals that serve disproportionately patients of Black race have worse outcomes than patients in other hospitals, but the modifiable nursing factors that may contribute to such disparities have not been explored. Objective The study objective was to examine whether nurse staffing differs in hospitals that serve predominantly patients of Black race (Black-serving hospitals) as compared to other hospitals. Methods A cross-sectional correlational design using a nurse survey in a national hospital sample was used to fulfill the study objective. Nurse staffing was measured as the maximum number of patients cared for on the last shift from the 2015 annual registered nurse survey conducted in National Database of Nursing Quality Indicators hospitals. Hospitals were classified into subgroups of low, medium, and high percentages of patients of Black race using the 2019 Medicare Provider Analysis and Review database. Results In survey data from 179,336 registered nurses in 574 hospitals, nurse staffing was significantly worse in high-Black-serving hospitals as compared to medium- and low-Black-serving hospitals. In Poisson regression models that adjusted for nursing unit type and hospital characteristics, nurses in high-Black-serving hospitals and medium-Black-serving hospitals had more patients-per-nurse than did nurses in low-Black-serving hospitals. Discussion Small, statistically significant differences in nurse staffing that are worse in hospitals where Black patients disproportionately access their care were found using nurse survey data accounting for nursing unit type. The poorer nurse staffing in Black-serving hospitals may compromise the care and outcomes of the seven in 10 hospitalized Black older adults who receive care in Black-serving hospitals. The consequences for patient outcome disparities of poorer nurse staffing in Black-serving hospitals deserve investigation. Policies to increase nurse staffing in hospitals serving a higher proportion of patients of Black race are needed to contribute to efforts to reduce health disparities.
