Objectives

Leishmaniasis poses a significant public health problem in Kenya, where effective case management and treatment rely on accurate diagnosis. This review aims to summarise the research landscape on leishmaniasis diagnostics in Kenya and identify gaps.

Design

This scoping review expands a previously published scoping review on leishmaniasis in Kenya to further analyse studies focusing on diagnostics. The field of diagnostics was chosen because of recent pushes for novel tools and because of the role timely diagnosis plays in disease elimination. A comprehensive search of PubMed, Embase via Embase.com, Web of Science Core Collection, the Cochrane Library, ClinicalTrials.gov, WHO ICTRP and the Pan African Clinical Trials Registry was conducted, covering studies up to 5 January 2024.

Results

After dual, blind screening with conflict resolution by a third reviewer, 41 studies were included in the review. These studies examined a range of diagnostic tools; however most were assessed in one or few studies, and none evaluated real-time PCR. Additional gaps in the research landscape include a lack of diagnostics for cutaneous leishmaniasis and post-kala-azar dermal leishmaniasis in Kenya, outdated literature surrounding the Direct Agglutination Test and randomised trials for any diagnostic tool.

Conclusions

Future research should focus on solidifying the validity and reliability of diagnostic tools in the Kenyan context and updating previous work.

Health systems adaptations to climate change: an umbrella review of global evidence protocol

Por: Dubas-Jakobczyk · K. · George · N. S. · Ndayishimiye · C. — Octubre 3rd 2025 at 06:32
Introduction

Health systems’ (HS) adaptations to climate change (CC) cover two major, and interrelated dimensions: (1) Environmental sustainability—actions aimed at limiting the negative impact of HS on the environment (eg, by reducing greenhouse gas emissions) and (2) Climate resilience—adaptations focused on improving HS’ ability to cope with the impact of CC (eg, by improving HS preparedness to climate-induced natural disasters). Within both dimensions, a diversity of actions, at different HS levels, can take place. The general objective is to provide health policy makers with a comprehensive evidence-based set of recommendations on the scope and effectiveness of HS adaptations to CC.

Methods and analysis

An umbrella review will be conducted. Systematic reviews will be included if: (1) They focus on HS adaptations to CC (including both environmental sustainability and climate resilience strategies/actions), (2) Were published since 2015 and (3) Report a quality appraisal of included studies. Five databases were searched: (1) MEDLINE via PubMed, (2) Scopus, (3) Web of science core collection, (4) ProQuest Central and (5) The Cochrane Database of Systematic Reviews. Two reviewers will independently assess studies’ eligibility, conduct quality appraisal and perform data extraction. Data will be synthesised using both quantitative and qualitative methods. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses will guide the reporting of results.

Ethics and dissemination

Ethical approval is not required, as this study involves the collection and analysis of secondary data only. The results will be submitted for publication in a peer-reviewed journal and disseminated via dedicated research channels and social media platforms.

Mindsets and menses: decoding young womens attitudes towards menstrual leave - an observational study from South India

Por: George · N. · Mahendran · P. · Kulothungan · K. · Dharmaraj · R. B. · Muniyapillai · T. · Subramanian · T. · Muthu Ranga Babu · A. · Arumugam · A. · Subramanian · S. · Shabash Khan · S. · Selvam · S. · Veeraragavan Suresh Babu · A. — Septiembre 30th 2025 at 09:49
Objective

The primary objective of this study is to investigate the perceived need and attitudinal perspectives regarding menstrual leave policies among young women in rural South India. The secondary objective was to determine the socio-demographic, menstrual and workplace-related factors associated with attitudes towards menstrual leave among young women.

Design

An analytical cross-sectional study was performed from May 2023 to August 2023.

Setting

In a rural district of Tamil Nadu, South India.

Participants

The study encompassed 955 young female students above 18 years of age enrolled in educational institutions in a rural district of Tamil Nadu, India. Participants were pursuing diverse professional programmes including medical, dental, allied health sciences, pharmacy and engineering courses.

Outcome measures

The primary outcomes included assessment of basic menstrual characteristics (age of menarche, regularity, product usage and pain experiences), pain evaluation using the WaLIDD scale (which measured working ability, anatomical pain location, pain intensity via Wong Baker scale and pain duration) and attitude assessment through a 10-dimension Likert scale. The attitude assessment explored both supportive factors (pain management, environmental considerations, medical leave allocation, menstruation normalisation and performance impact) and potential concerns (medicalisation, perceptions of fragility, stigma, disclosure issues and abnormal leave usage). Secondary outcome measures encompassed the analysis of factors influencing these attitudes, followed by a multivariable linear regression model to identify significant predictors.

Results

Among 955 female students (mean age 19.56±1.33 years), the majority supported menstrual leave for maintaining hygiene (82.3%) and managing dysmenorrhoea (75.8%). A substantial proportion (64.4%) viewed it as a means of normalising menstruation discourse, while 61.6% believed it could enhance workplace performance. However, concerns existed about medicalising menstruation (47.9%) and reinforcing gender stereotypes (43.4%). Multivariate analysis revealed that medical students (B=0.67, 95% CI: 1.34 to 2.00), those with graduate-educated fathers (B=1.64, 95% CI: 0.31 to 2.97), earlier age at menarche (B=–0.23, 95% CI: –0.45 to –0.01) and participants reporting menstrual interference with daily activities (B=0.96, 95% CI: 0.02 to 0.89) held significantly more positive attitudes.

Conclusion

While young women generally support menstrual leave policies, particularly for hygiene and pain management, there are significant concerns about workplace stigmatisation and gender stereotyping. Educational background, parental education and personal menstrual experiences significantly influence attitudes toward menstrual leave. These findings suggest the need for carefully structured menstrual leave policies that balance biological needs with workplace/student place equality concerns.

Crowded housing, indoor environment and childrens respiratory, allergic and general health in Sweden: a cross-sectional study

Por: Eiffener · E. · Murekatete · R. · Merritt · A.-S. · Georgelis · A. · Fahlen Zelander · C. · Al-Nahar · L. · Jakobsson · K. · Albin · M. · Bergström · A. · Jonsson · M. · Eriksson · C. — Septiembre 24th 2025 at 03:32
Objectives

The aim of this study was to analyse associations between crowded housing and children’s indoor living environment, respiratory and allergic disorders and general health.

Design

A cross-sectional study.

Setting

Sweden, using data from the Swedish National Environmental Health Survey 2019.

Participants

The study sample included 48 512 children (aged 6–10 months, 4 years and 12 years). We also investigated associations in vulnerable subgroups, such as children with asthma and those living under unfavourable socioeconomic conditions.

Primary and secondary outcome measures

Primary outcomes in the living environment were at least one sign of mould, poor indoor air quality, unpleasant odours, too warm indoors in summer and too cold indoors in winter. Primary outcomes for children’s health were asthma, airway problems, breathing difficulties, rhinitis symptoms, mould and mites allergy, pollen allergy, furred pet allergy and good general health.

Results

About one in five children lived in an overcrowded home. Factors from the indoor living environment such as perceived poor indoor air quality and mould were significantly associated with crowded housing. Moreover, children who lived in overcrowded conditions were less likely to report good general health than children in non-crowded households (OR 0.64, 95% CI 0.54 to 0.76). This association was even stronger in children with asthma (OR 0.51, 95% CI 0.34 to 0.77). Few significant associations were, however, observed with the respiratory and allergic health outcomes.

Conclusions

Crowded housing is associated both with a poor indoor environment and with poorer general health in children. Children with asthma may experience even poorer general health.

A volumetric modulated arc therapy-based dynamic conformal arc technique with limited monitor units (VMAT<sub>liMU</sub>) to reduce multileaf collimator interplay effects: A computational phantom study for stage I non-small-cell lung cancer

Por: Dong Min Jung · Yong Jae Kwon · Yong Wan Cho · Jong Geol Baek · Dong Jae Jang · Yongdo Yun · Seok-Ho Lee · Gahee Son · Hyunjong Yoo · Min Cheol Han · Jin Sung Kim — Septiembre 9th 2025 at 16:00

by Dong Min Jung, Yong Jae Kwon, Yong Wan Cho, Jong Geol Baek, Dong Jae Jang, Yongdo Yun, Seok-Ho Lee, Gahee Son, Hyunjong Yoo, Min Cheol Han, Jin Sung Kim

Volumetric modulated arc therapy (VMAT) for lung cancer involves complex multileaf collimator (MLC) motion, which increases sensitivity to interplay effects with tumour motion. Current dynamic conformal arc methods address this issue but may limit the achievable dose distribution optimisation compared with standard VMAT. This study examined the clinical utility of a VMAT technique with monitor unit limits (VMATliMU) to mimic conformal arc delivery and reduce interplay effects while maintaining plan quality. VMATliMU was implemented by applying monitor unit limitations during VMAT reoptimisation to minimise MLC encroachment into target volumes. Using mesh-type reference computational phantom CT images, treatment plans were generated for a simulated stage I lung cancer case prescribed to 45 Gy in three fractions. VMATliMU, conventional VMAT, VMAT with leaf speed limitations, dynamic conformal arc therapy, and constant dynamic conformal arc therapy were compared. Plans were optimised for multiple isodose line prescriptions (50%, 60%, 70%, 80%, and 90%) to investigate the impact of dose distribution. Evaluation parameters included MLC positional accuracy using area difference ratios, dosimetric indices, gradient metrics, and organ-at-risk doses. VMATliMU prevented MLC encroachment into the internal target volume across 60%–90% isodose lines, showing superior MLC accuracy compared with other methods. At the challenging 50% isodose line, VMATliMU had 4.5 times less intrusion than VMAT with leaf speed limits. VMAT plans had better dosimetric indices than dynamic conformal arc plans. VMATliMU reduced monitor units by 5.1%–19.2% across prescriptions. All plans met the clinical dose constraints, with the aortic arch below tolerance and acceptable lung doses. VMATliMU combines VMAT’s dosimetric benefits with the dynamic conformal arcs’s simplicity, minimising MLC encroachment while maintaining plan quality. Reduced monitor units lower low-dose exposure, treatment time, and interplay effects. VMATliMU is usable in existing planners with monitor unit limits, offering a practical solution for lung stereotactic body radiation therapy.

Psychological outcomes in paediatric major trauma patients who require invasive management: protocol for a systematic review and meta-analysis

Por: Hibberd · O. · Thomas · C. E. · Gentle · S. · Angus · S. · Karageorgos · S. · Phillips · V. · Thomas · S. H. — Agosto 19th 2025 at 15:52
Introduction

Paediatric major trauma patients with more severe injuries and physiological or biochemical abnormalities as a result of the injury are more likely to require invasive management in the form of an operation/interventional radiology (IR). Adverse psychological outcomes, such as post-traumatic stress disorder, anxiety, depression and adjustment disorder, are frequently observed in paediatric patients with major trauma. Similarly, it is recognised that children and adolescents who have invasive management are also at an increased risk of adverse psychological outcomes. However, it is not known to what extent major trauma patients requiring invasive management are at risk of adverse psychological outcomes compared with those managed conservatively. This study aims to determine whether paediatric major trauma patients who require an operation/IR have increased odds of having an adverse psychological outcome compared with those who are managed conservatively.

Methods and analysis

The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines will be used to construct this review. The databases Medline (via Ovid), Embase (via Ovid), PsycInfo (via Ebscohost) and Cinahl (via Ebscohost) will be searched from inception to February 2025. Both title and abstract screening and full-text screening will be done by two reviewers, with an adjudicating third reviewer. For randomised controlled trials, the Cochrane Risk of Bias Tool will be employed, while for non-randomised studies, the Newcastle-Ottawa Quality Assessment Scale will be used. We will assess bias using contoured funnel plots (with p set at 0.01, 0.05 and 0.10), non-parametric trim-fill analysis, leave-one-out analysis and Galbraith plotting. We will execute formal (Egger) testing for funnel plot asymmetry and also calculate prediction intervals if sufficient study N of 10 is accrued. Certainty and confidence in cumulative evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

Ethics and dissemination

Ethical review is not required as no original data will be collected. Results will be disseminated through peer-reviewed publications and at academic conferences.

Creating an evidence map of the safety profile of spironolactone across all clinical indications to establish whether it may be a safe treatment in female adolescent acne: a protocol for a scoping review

Por: Sexton · F. C. · Attard · M. · OHiggins · L. · Moledina · Z. · Fordham · J. · Ramesh · G. · Law · J. · George · S. · Burden-Teh · E. — Agosto 19th 2025 at 15:52
Introduction

Spironolactone is a useful and effective acne treatment option for adult female patients. We aim to establish whether spironolactone could be a safe treatment for the management of acne in the female adolescent population as well. The objective of this scoping review is to provide an evidence map of the safety profile of spironolactone in the paediatric population aged 0–17 across all clinical indications.

Methods and analysis

This scoping review will be conducted according to the Joanna Briggs Institute scoping review protocol. Relevant publications will be searched on the MEDLINE, Embase and Web of Science databases from inception until July 2025. The authors of included studies will be contacted using contact details provided in the manuscript to check for any further published or unpublished data on the review question. An initial search will be conducted using keywords to identify relevant articles. After identifying the research strategy, articles will be extracted into a reference management tool, and a two-part study selection process will be systematically applied by two reviewers. The first part consists of screening titles and abstracts to define the eligibility of each article. In the second part, the full texts will be screened and only relevant articles will be kept. All articles related to the safety of spironolactone in children and adolescents across all clinical indications will be included. Data will be extracted using a scoping review management software such as Covidence, collated and charted to summarise all the relevant methods, outcomes and key findings in the articles.

Ethics and dissemination

This scoping review will provide an extensive overview of the available safety evidence for the use of spironolactone in children and teenagers. Since the scoping review methodology consists of reviewing and collecting data from publicly available materials, this study does not require ethics approval. The results will be disseminated in a peer-reviewed publication.

A Review of Chronic Wounds and Their Impact on Negative Affect, Cognition, and Quality of Life

Por: Maria C. Redmond · Georgina Gethin · David P. Finn — Agosto 17th 2025 at 09:00

ABSTRACT

Chronic wounds represent a substantial socioeconomic, financial, and psychological burden. We examine preclinical and clinical evidence assessing the impact of chronic wounds on negative affect, cognition, and quality of life and discuss potential mechanisms underlying the link between chronic wounds and negative affect and cognition. There is limited preclinical evidence examining negative affect and wounds, but anxiety-related behaviour has been reported in a rat incisional wound model. The incidence of anxiety and depression in people with chronic wounds varies considerably. Potential mechanisms underlying the link between chronic wounds and negative affect include the immune system, pain, metabolic dysfunction, inflammation, and vascular damage. There is a paucity of both preclinical and clinical studies examining the effect of chronic wounds on cognition, highlighting a need for more studies in this area. Research suggests that there are deficiencies in the management of anxiety, depression, and cognitive impairment in people with chronic wounds, but developing and administering therapies that target these comorbidities may have a positive impact on quality of life and wound healing. Integration of mental health and cognition screening into wound care protocols would provide substantial benefits both socioeconomically and to individuals with chronic wounds.

Electrical Burns: A Retrospective Study at the Lebanese Burn Center in Geitaoui Hospital, Lebanon (2011–2024)

Por: Elie Moukawam · Charbel Bechara Aoun · Joseph Sfeir · Ziad Hankach · Rita Chebl · Georges Ghanime · Ziad Sleiman — Julio 26th 2025 at 01:48

ABSTRACT

Electrical burns are among the most severe burn injuries, often leading to deep tissue damage, systemic complications, and prolonged hospitalisation. In Lebanon, limited national data on electrical burn injuries limits the understanding of their epidemiology and management. This study aims to assess the prevalence and characteristics of electrical burns in patients admitted to the specialised burn care unit in Geitaoui Hospital in Lebanon. A retrospective observational study was conducted by reviewing the medical records of patients admitted from 1st January 2011 to 31st December 2024. Data on demographics, burn characteristics, hospitalisation outcomes, infections, surgical interventions, and laboratory findings were extracted and analysed using SPSS version 26. Thirty patients were included, with a male predominance (96.7%) and the mean age was 29.6 years. Third-degree burns were observed in 70.0% of cases, and 66.7% of patients had burns affecting 10%–30% of their total body surface area. High-voltage injuries accounted for 50.0% of cases. Upper extremities were the most commonly affected site (93.3%). The mean hospital stay was 25.69 days, and the mortality rate was 10.0%. Infection was documented in 43.3% of cases. The most frequently isolated pathogens were Acinetobacter (20.0%) and Pseudomonas aeruginosa (16.7%). Surgical intervention was required in 63.3% of patients, most frequently skin grafting (36.7%). This study contributes national data on electrical burns and emphasises the importance of preventive and multidisciplinary care strategies.

Analysis of buprenorphine distribution patterns among pharmacies and hospitals in the USA from 2019 to 2023

Por: Gikoska · M. · Florio · A. K. · George · A. · Piper · B. J. — Julio 21st 2025 at 02:01
Background

Opioid use disorder (OUD) is a debilitating condition characterised by the overuse of opioid medications and the development of physical and/or psychological dependence. Consequences of this condition include chronic impairment, distress and later life-altering health conditions such as overdose, all of which have been highlighted by the prominence of OUD in the USA in recent years. Buprenorphine is a standard OUD treatment and commonly used for pain management. Understanding changes in distribution patterns across the USA is vital for continuing to improve outcomes for OUD patients.

Methods

This study used the Drug Enforcement Administration’s Automated Reports and Consolidated Ordering System (ARCOS) and the US Census Bureau Population Estimates databases to analyse changes in buprenorphine distribution among pharmacies and hospitals from 2019 to 2023, to determine temporal patterns and to identify state-level disparities using the data. The data were corrected for population to identify patterns of buprenorphine distribution in the USA from 2021 to 2022 and 2022 to 2023 through examining percent changes in milligrams per 100 population at the national and state levels.

Results

The year-to-year percent change of national buprenorphine distribution from pharmacies has remained positive but changed from a 12.2% increase from 2019 to 2020 (figure 4) to a four per cent increase every year from 2020 to 2023. From 2021 to 2022, there was a +4.9% increase in total grams of buprenorphine distributed to pharmacies and a 95% CI [–5.1, 14.9], with the District of Columbia, South Dakota and Nebraska outside of the 95% CI. Distribution to hospitals increased by 10.2% [-32.3, 52.7] during 2021–2022, with Hawaii, New Hampshire and Delaware being outside of 95% CI. From 2022 to 2023, there was an increase of +5.7% and 95% CI [–3.5, 14.9] in pharmacy distribution, with states including Washington, Rhode Island and Kansas remain outside of the 95% CI. Hospital distribution has decreased from twenty per cent between 2019 and 2020 (figure 4) to eighteen per cent between 2022 and 2023.

Conclusion

Following increases in buprenorphine distribution during the COVID pandemic, a consistent increase has continued year-over-year in most states and the country overall by both pharmacies and hospitals. Some states (eg, Rhode Island, Georgia, District of Columbia) have not followed this pattern. Notably, Hawaii went from the most negative percent change in hospital distribution to the most positive change in the timeframe analysed. This may offer opportunities to analyse more specific impacts of the increased buprenorphine distribution on populations and their outcomes associated with OUD.

Evaluation of a virtual reality-directed brain-gut behavioural treatment inpatient program for patients with inflammatory bowel disease: protocol for a pilot feasibility trial

Por: Gutermuth · B. · Jordan · A. · Hodish · G. · Sturgeon · J. A. · DeJonckheere · M. · Berinstein · J. A. · Sheehan · J. · Bishu · S. · Higgins · P. D. · Cohen-Mekelburg · S. — Julio 4th 2025 at 04:45
Introduction

Pain is one of the most bothersome symptoms that affects patients with inflammatory bowel disease (IBD) but is often inadequately treated. Inadequate pain control in the inpatient setting not only impacts patients’ experience but increases opioid use and hospital length of stay. Opioids are often considered first-line treatment for severe pain but are associated with significant morbidity and mortality in IBD. Non-steroidal anti-inflammatory drugs are a non-opioid analgesic option, but concerns regarding their contribution to IBD flares have limited their use. Brain-gut behavioural therapies (BGBT), such as cognitive behavioural therapy, meditation and gut-directed hypnotherapy, are effective for pain management and have a role in the treatment of IBD symptoms. However, the use of BGBT in IBD is challenging, given limited access to behavioural health specialists, especially in the inpatient setting. Virtual reality (VR)-directed BGBT programmes can bridge this gap and enhance pain treatment for inpatients with IBD. Therefore, in this study, we aim to establish feasibility and acceptability for a VR-directed BGBT inpatient programme for patients with IBD.

Methods and analysis

We will recruit 40 patients with IBD who are hospitalised at Michigan Medicine and who endorse IBD-related pain. We will assess patient-reported outcomes (pain rating, IBD-specific symptoms, perceived stress, mood) before and after treatment, cumulative inpatient analgesic requirements and hospital length of stay. Our primary objective will be to establish intervention feasibility defined by the frequency and percentage of enrolled participants that use the VR-directed BGBT inpatient intervention in any capacity. Our secondary objective will be to evaluate intervention acceptability by conducting semistructured interviews with study participants. We will also explore the preliminary effectiveness of VR-directed BGBT on patient-reported outcomes and healthcare utilisation as compared with historic controls.

Ethics and dissemination

The study was approved by the institutional review board of the University of Michigan Medical School on 10 October 2023 (HUM00240999). All human subjects will be required to sign an informed consent document prior to study participation. Study findings will be reported through peer-reviewed publication.

Knowledge, Attitude and Practices Towards Thermal Burns: A Cross‐Sectional Study in the Lebanese Population

ABSTRACT

This study investigates the knowledge, attitudes, and practices of the Lebanese population regarding thermal burns to inform targeted interventions. Using a cross-sectional design, data was collected from 1090 participants though a structured questionnaire. Key findings revealed a mean knowledge score of 14.89/20, indicating moderate understanding, with gaps in identifying third-degree burns and optimal cooling durations. Attitudes scores averaged 36.97/50, reflecting a strong support for burn prevention but low confidence in first aid. Practices scored 12.37/20, with many participants adhering to safety measures but relying on unverified remedies and lacking emergency preparedness. Significant correlations were found between the three domains, particularly between knowledge and practices (r = 0.328, p < 0.001), emphasising the role of education and attitudes in shaping behaviours. Multivariate analysis identified formal first aid training, education, and urban residency as strong predictors across all three domains, while older age negatively influenced knowledge. These results underscore the need for culturally tailored education and enhanced training to address gaps in burn prevention and management among the Lebanese population.

ASSIST: Development of a Simplified Clinician–Patient Hybrid Reporting Outcome Measure for Remote Diagnosis of Surgical Site Infection

ABSTRACT

Remote assessment of surgical site infection(SSI) lacks sensitivity for the diagnosis of SSI, but current evidence has not evaluated whether a combination of photographs and questionnaires improves diagnostic accuracy. This study aims to develop a remote diagnostic measure to identify SSI. A two-phase mixed methods study was conducted. In phase I, five clinicians reviewed the Bluebelle wound healing questionnaire(WHQ) on a five-point Likert scale of agreement for inclusion in a remote measure. Discussion generated a hypothesis as to which items should be included. In phase II, a cohort study, whereby clinicians evaluated patient's wound images and patients completed the WHQ, were reviewed for scale structure. Principal component analysis (PCA) with scree plot examination and maximum likelihood of estimation (MLE) for one, two and three factors were evaluated. Internal consistency was assessed with Cronbach's α. Phase I: hypothesis generation estimated a measure containing between 10 and 12 items would include all relevant items without ambiguity or redundancy. Phase II: a combined sample of 570 responses provided clinician reviewed images and patient responses. PCA suggested that a 12-item measure with a combined variance of 60.2% would have the best model fit. Cronbach's α was high at 0.841. One included item was highlighted as potentially ambiguous in phase I (wound pain), providing an additional model with this removed. MLE for one, two and three factors suggested measures with 8, 10 and 11 items, respectively. Total variances were low at 29.7%, 39.8% and 41.4% and Cronbach's α were high at 0.838, 0.827 and 0.823, respectively. Three potential models for a remote diagnostic measure were identified. Each is shorter than alternative available measures, which have not been designed for combined use, ensuring this is easy to use. Further evaluation for reliability and diagnostic accuracy is needed to validate a final measure that can be implemented in clinical practice.

Lung cancer screening with volume computed tomography is cost-effective in Greece

by Xuanqi Pan, Katerina Togka, Hilde ten Berge, Lisa de Jong, Harry Groen, Maarten J. Postma, Eleftherios Zervas, Ioannis Gkiozos, Christoforos Foroulis, Kyriaki Tavernaraki, Sofia Lampaki, Georgia Kourlaba, Antonios Moraris, Sofia Agelaki, Konstantinos Syrigos

Objective

This study aimed to assess the cost-effectiveness of lung cancer screening (LCS) employing volume-based low-dose computed tomography (LDCT) in contrast to the absence of screening, targeting an asymptomatic high-risk population in Greece, leveraging the outcomes derived from the NELSON study, the largest European randomized control trial dedicated to LCS.

Methods

A validated model incorporating a decision tree and an integrated state-transition Markov model was used to simulate the identification, diagnosis, and treatments for a population at high risk of developing lung cancer, from a healthcare payer perspective. Screen-detected lung cancers, costs, life years (LYs), quality-adjusted life years (QALYs), and the incremental cost-effectiveness ratio (ICER) were predicted. Sensitivity and scenario analyses were conducted to assess the robustness and reliability of the model’s outcomes under varying parameters and hypothetical situations.

Results

Annual LCS with volume-based LDCT detected 17,104 more lung cancer patients at early-stage among 207,885 screening population, leading to 8,761 premature lung cancer deaths averted. In addition, in contrast to no screening, LCS yielded 86,207 LYs gained and 50,207 incremental QALYs at an additional cost of €278,971,940, resulting in an ICER of €3,236 per LY and €5,505 per QALY, over a lifetime horizon. These estimates were robust in sensitivity analyses.

Conclusions

LCS with volume-based LDCT, targeting an asymptomatic high-risk population, is highly cost-effective in Greece. Implementing LCS ensures efficient allocation of public healthcare resources while delivering substantial clinical benefits to lung cancer patients.

Characterizing temporal and global host innate immune responses against SARS-CoV-1 and -2 infection in pathologically relevant human lung epithelial cells

by Vivian Y. Tat, Aleksandra K. Drelich, Pinghan Huang, Kamil Khanipov, Jason C. Hsu, Steven G. Widen, Chien-Te Kent Tseng, George Golovko

Severe acute respiratory syndrome coronavirus-1 (SARS-CoV-1) and -2 (SARS-CoV-2) are beta-coronaviruses (β-CoVs) that have caused significant morbidity and mortality worldwide. Therefore, a better understanding of host responses to β-CoVs would provide insights into the pathogenesis of these viruses to identify potential targets for medical countermeasures. In this study, our objective is to use a systems biology approach to explore the magnitude and scope of innate immune responses triggered by SARS-CoV-1 and -2 infection over time in pathologically relevant human lung epithelial cells (Calu-3/2B4 cells). Total RNA extracted at 12, 24, and 48 hours after β-CoVs or mock infection of Calu-3/2B4 cells were subjected to RNA sequencing and functional enrichment analysis to select genes whose expressions were significantly modulated post-infection. The results demonstrate that SARS-CoV-1 and -2 stimulate similar yet distinct innate antiviral signaling pathways in pathologically relevant human lung epithelial cells. Furthermore, we found that many genes related to the viral life cycle, interferons, and interferon-stimulated genes (ISGs) were upregulated at multiple time points. Based on their profound modulation upon infection by SARS-CoV-1, SARS-CoV-2, and Omicron BA.1, four ISGs, i.e., bone marrow stromal cell antigen 2 (BST2), Z-DNA Binding Protein 1 (ZBP1), C-X-C Motif Chemokine Ligand 11 (CXCL11), and Interferon Induced Transmembrane Protein 1 (IFITM1), were identified as potential drug targets against β-CoVs. Our findings suggest that these genes affect both pathogens directly and indirectly through the innate immune response, making them potential targets for host-directed antivirals. Altogether, our results demonstrate that SARS-CoV-1 and SARS-CoV-2 infection induce differential effects on host innate immune responses.

Frailty and comorbidity in older adults with and without diabetes and chronic leg ulcer: A cross‐sectional study

Abstract

This descriptive, cross-sectional study aimed to identify whether having a chronic leg ulcer (CLU), in addition to diabetes, contributed to frailty in individuals ≥65 years old. It also explored the associations between frailty, pre-frailty and other factors. 125 participants aged ≥65 attending outpatient clinics in Ireland were categorised into three groups: (1) diabetes-only and no CLU, (2) CLU-only and no diabetes, and (3) diabetes and CLU. Frailty status was identified using the Groningen Frailty Indicator (GFI) and the Physical Frailty Phenotype (PFP). The mean age was 76.09 ± 7.31. Overall, 90 (72%) had diabetes, and 89 (71.2%) had CLU in the past 6 months. While 124 (99.2%) were frail according to the GFI, 122 (97.6%) were either physically frail (n = 40, 32%) or pre-frail (n = 82, 65.6%) based on the PFP. There was no difference between the three groups regarding general frailty status (p > 0.05). However, being aged ≥75, having CLU and having CLU in addition to diabetes were associated with frailty severity (p < 0.05). Slow gait, inability to go to the toilet and dress/undress independently were the common factors contributing to frailty. Age, comorbidities and CLU were associated with frailty severity. Incorporating multidimensional frailty screening into regular clinic visits for older adults with CLU is recommended.

HIV acquisition risk with norethisterone (NET) enanthate (NET-EN) is reportedly less than for depo-medroxyprogesterone acetate intramuscular (DMPA-IM). We investigated the effects of these progestin-only injectable contraceptives on serum testosterone and sex hormone binding globulin (SHBG) levels, since these may play a role in sexual behavior and HIV acquisition. The open-label WHICH clinical trial, conducted at two sites in South Africa from 2018–2019, randomized HIV-negative women aged 18–40 years to 150 mg DMPA-IM 12-weekly (n = 262) or 200 mg NET-EN 8-weekly (n = 259). We measured testosterone by UHPLC-MS/MS and SHBG by immunoassay in matched pairs of serum samples collected at baseline (D0) and at peak serum progestin levels at 25 weeks post initiation (25W) (n = 214–218 pairs). Both contraceptives substantially decreased, from D0 to 25W, the total testosterone [DMPA-IM D0 0.560, 25W 0.423 nmol/L, -24.3% (p

Nurses' experiences of hospital‐acquired pressure injury prevention in acute healthcare services in Victoria, Australia: A qualitative study using the Theoretical Domains Framework

Abstract

We investigated nurses' experiences of hospital-acquired pressure injury (PI) prevention in acute care services to better understand how PI prevention may be optimised. We used the Theoretical Domains Framework to systematically identify barriers and enablers to evidence-based preventive practices as required by the International Guideline. This study was one element of a complex capacity building project on PI surveillance and prevention within the acute health service partners of Monash Partners Academic Health Science Centre, an accredited academic health partnership located in Melbourne, Australia. We adopted a qualitative descriptive design. We interviewed 32 nurses that provided care in intensive care units, general wards and COVID wards of four acute care services. Nurses were recruited from four large acute care services (three public, one private) located in Melbourne. Most of them worked with patients who were at high risk of hospital-acquired PI on a daily basis. Interview transcripts were coded and analysed using thematic analysis guided by the Theoretical Domains Framework. The domains referred to most frequently by all participants included: Knowledge, Skills, Social/Professional Role and Identity, Beliefs about Capabilities, and Environmental Context and Resources. The key barriers discussed by nurses included gaps in nurses' knowledge and skills related to identification and staging of PI, heavy nursing workload and inadequate staffing levels, stigma and self-blame related to PI identification, and exacerbating impacts of the COVID-19 pandemic. Main facilitators discussed were training programmes, nursing audits and feedback, and teamwork. Participants suggested improvements including accessible and tailored training, visual reminders, and addressing heavy workloads and emotional barriers nurses face. Investing in tailored training initiatives to improve nurses' knowledge and organisational changes to address low level staffing and heavy workloads are urgently needed to support nurses in delivering optimal care and preventing hospital-acquired PI.
