Abstract
Background
Nosocomial infections (NI) significantly worsen patient outcomes, resulting in higher mortality rates and reduced health-related quality of life. Furthermore, they pose substantial economic strain on healthcare systems and hospitals. For instance, patients with nosocomial infections (NIs) experience prolonged hospital stays compared to those without NIs. These extended stays result in occupied bed-days, leading to opportunity costs for hospitals. This study aimed to estimate the opportunity costs for a German hospital based on hospital stays, daily revenue, and occupancy rates (OCR).

Methods
We analysed cost data obtained from routine records maintained by the accounting department of a German hospital's surgical and orthopedic units from 2018 to 2019 for the “HygArzt” research project. To ensure balance, we employed genetic matching. We estimated the differences in length of stay (LOS) and daily revenue between patients with and without nosocomial infections (NI) using linear regression. Finally, we calculated the opportunity cost borne by the hospital by treating NI patients instead of non-NI patients. All costs are reported in 2018 Euros.

Results
The final sample included 81 patients with NI matched with 207 patients without NI. The majority of the NI patients (77.0%) had surgical site infection (SSI). Compared to non-NI patients, we observed that NI patients had a longer LOS (10 days, p < 0.001) and lower daily revenue (€400, p < 0.001). We also found that comorbidities and the frequency of operations had significant impact on the LOS. Using a baseline 30 to 50% preventable NIs, successful prevention of a single NI could potentially reduce the length of hospital stay by 3 to 5 days and increase hospital revenue by approximately €120 to €200 per day per prevented NI. Consequently, the hospital saves 3 to 5 more bed-days to backfill and generate more revenue, and/or make more efficient resource allocation by changing bed-capacity and staffing. The resulting opportunity costs can potentially exceed €1,000 per preventable case.

Conclusion
NIs pose a substantial economic burden for hospitals. From a health economics’ perspective, there are strong economic incentives for hospitals to implement infection control interventions, such as the involvement of a prevention link physician/nurse.
A systematic literature review on how consumer and community involvement have shaped and influenced pre-pregnancy care interventions for women with diabetes
Authors: Hicks Rachel , Dune Tinashe , Gu Veronica , Simmons David , MacMillan Freya 
Published: November 2024

Abstract
Background
Diabetes and pregnancy studies have found better outcomes when interventions were developed with consumer (individuals with lived experience of diabetes) and community involvement. When consumers are central to development and delivery of interventions, study participants have better engagement and outcomes, particularly for individuals from culturally and linguistically diverse (CALD) and/or lower socio-economic backgrounds. Our study aims to examine the scope of consumer and community involvement (CCI) in the construction and implementation of pre-pregnancy care (PPC) interventions and discuss a framework for consumer-lead intervention development.

Methods
A systematic literature review was conducted, examining 3 electronic databases. A meta synthesis analysis of tabulated data summarized in a literature matrix was undertaken with a phenomenological approach to develop a Pre-Pregnancy Care CCI-Driven Intervention Framework.

Results
Overall, 4642 papers were identified, with 29 meeting inclusion criteria. The meta-synthesis and literature matrix identified several common themes across previous studies. These were: barriers to accessing (PPC) such as negativity and stigma in care from behaviours, attitudes and perceptions of HCPs; limited appointment availability not aligning with work and family commitments; fear of losing a “normal” pregnancy journey; awareness of risk but unwillingness to discuss if consumers have not established trust with HCPs; inaccessibility to CALD appropriate PPC and contraception; and digitisation of PPC information resources including peer support and social media. From these results, a PPC Consumer-Driven Intervention Framework for Women with Pregestational Diabetes was developed with recommendations.

Conclusion
Consumers have been under-involved in the majority of previous developments and implementation of interventions for women with diabetes and pregnancy, and their representation as stakeholders in interventions is paramount to the longevity of intervention outcomes. To assist community involvement in diabetes pregnancy intervention design and delivery we created a new framework, for improving clinical and social outcomes in healthcare, empowering relationships between HCPs and consumers, and highlighting the value of lived experience and women-centred care for increased community engagement.

Published: November 2024

Abstract
Background
Gestational weight gain (GWG) is a critical issue related to postpartum health in newborns and mothers. In Brazil, pregnant women’s public health recommends monitoring GWG. Therefore, the objective of this study is to evaluate gestational weight gain and associated health factors of pregnant women monitored at Unified Health System (SUS) in the city of São Paulo between 2012 and 2020.

Methods
This is a retrospective cohort study of pregnant women seen from 2012 to 2020 in São Paulo, Brazil. The database used was from the Integrated Health Care Management System related to the Live Birth Information System. Data distribution was assessed using the Kolmogorov-Smirnov test. Comparisons between groups according to weight gain (LWG vs. AWG vs. EWG) were performed using analysis of variance (ANOVA) with Tukey post hoc. Inclusion criteria considered that pregnant women had a recorded initial weight before 13 weeks and up to 15 days before delivery and a single pregnancy. The final database includes 276.220 pregnant women.

Results
The frequency of women according to initial body mass index (BMI) was 12.004 (4.4%) underweight, 132.049 (48.3%) normal weight, 78.856 (28.8%) overweight, and 50.660 (18.5%) living with obesity. The population consisted of 59.881 (21.9%), 37.217 (13.6%) and 176.471 (64.5%) women with LWG, AWG and EWG, respectively. Weight gain was associated with initial BMI, type of birth, color/ethnicity, marital status, women’s age and antenatal care visits.

Conclusion
The proportion of pregnant women with inadequate weight gain is high, relating initial BMI, type of birth, color/ethnicity, marital status, women’s age and antenatal care visits. Interventions such as nutritional education should be suggested to help achieve adequate GWG.

Published: November 2024

Abstract
Background
African, Caribbean, and Black im/migrant women experience a disproportionate burden of HIV relative to people born in Canada, yet there is scarce empirical evidence about the social and structural barriers that influence access to HIV care. The objectives of this study is to estimate associations between African, Caribbean, and Black background and stigma and non-consensual HIV disclosure outcomes, and to understand how experiences of stigma and im/migration trajectories shape access to HIV care and peer supports among African, Caribbean, and Black im/migrant women living with HIV in Canada.

Methods
This mixed-methods analysis draws on interviewer-administered questionnaires and semi-structured interviews with self-identifying African, Caribbean, and Black women living with HIV in the community-based SHAWNA (Sexual Health and HIV/AIDS: Women’s Longitudinal Needs Assessment) cohort. Bivariate and multivariable logistic regression using generalized estimating equations (GEE) were performed to estimate associations between African, Caribbean, and Black background and stigma and non-consensual HIV disclosure outcomes. Drawing on a social and structural determinants of health framework, qualitative analysis of interviews elucidated the interplay between migration trajectories, stigma, racialization, and HIV.

Results
Amongst our participants (n = 291), multivariable GEE analysis revealed that African, Caribbean, and Black participants (n = 15) had significantly higher odds of recently being outed without consent as living with HIV (AOR 2.34, 95% CI 0.98–5.57). Additionally, African, Caribbean, and Black participants had higher odds of recent verbal or physical abuse due to their HIV status (AOR 2.11, 95% CI 0.65–6.91). Reflecting on their im/migration trajectories, participants’ narratives (n = 9) highlighted experiences of political violence and conflict, trauma, stigma, and discrimination associated with HIV in their place of origin and the racialization and stigmatization of HIV in Canada. Fear of disclosure without consent was linked to barriers of accessing care and peer-based supports.

Conclusion
Our findings indicate that im/migration trajectories of African, Caribbean, and Black women living with HIV are critically related to accessing HIV care and supports in Canada and compound HIV stigma and discrimination. HIV disclosure without consent complicates access to care and social/peer support, underscoring the need for privacy, confidentiality, and the importance of building trust in the context of clinical encounters. The results of this study emphasize the critical need for culturally sensitive trauma-informed care models rooted in peer-based approaches.
Volatiles extracted from Melaleuca Rugulosa (Link) Craven leaves: comparative profiling, bioactivity screening, and metabolomic analysis

Published: November 2024

Abstract
Background
Melaleuca species (family Myrtaceae) are characterized by their wide-ranging applications as antimicrobials and in skin-related conditions. Herein, we estimated the volatile profile and biological significance of M. rugulosa (Link) leaves for the first time supported by a dereplication protocol.

Materials and methods
Volatile components were extracted using hydrodistillation (HD), supercritical fluid (SF), and headspace (HS) techniques and identified using GC/MS. The variations among the three extracts were assessed using principal component analysis and orthogonal partial least square discriminant analysis (OPLS-DA). The extracted volatiles were tested for radical scavenging activity, anti-aging, and anti-hyperpigmentation potential. Finally, disc diffusion and broth microdilution assays were implemented to explore the antibacterial capacity against Streptococcus pyogenes, Staphylococcus aureus, Clostridium perfringens, and Pseudomonas aeruginosa.

Results
The yield of the SF technique (0.8%) was three times higher than HD. GC/MS analysis revealed that the oxygenated compounds are the most proponents in the three extracts being 95.93% (HD), 80.94% (HS), and 48.4% (SF). Moreover, eucalyptol (1,8-cineol) represents the major component in the HD-EO (89.60%) and HS (73.13%) volatiles, while dl-α-tocopherol (16.27%) and α-terpineol (11.89%) represent the highest percentage in SF extract. Regarding the bioactivity profile, the HD-EO and SF-extract showed antioxidant potential in terms of oxygen radical absorbance capacity, and β- carotene assays, while exerting weak activity towards DPPH. In addition, they displayed potent anti-elastase and moderate anti-collagenase activities. The HD-EO exhibited potent anti-tyrosinase activity, while the SF extract showed a moderate level compared to tested controls. OPLS-DA and dereplication studies predicted that the selective antibacterial activity of HD-EO to S. aureus was related to eucalyptol, while SF extract to C. perfringens was related to α-tocopherol.

Conclusions
M. rugulosa leaves are considered a vital source of bioactive volatile components that are promoted for controlling skin aging and infection. However, further safety and clinical studies are recommended.
Higher interest to continue COVID-19 practice recommendations in non-pandemic times among German GPs with better crisis leadership skills (egePan study)
Authors: Aretz Benjamin , Krumpholtz Yelda , Kugai Simon , Amarell Nicola , Schmidt Manuela , Weltermann Birgitta 
Published: November 2024

Abstract
Background
The German College of General Practitioners and Family Physicians (DEGAM) issued a COVID-19 guideline with eleven recommendations to support primary care services during the pandemic. Their use in general practices beyond the pandemic can contribute to pandemic preparedness. This study analysed general practitioners’ (GPs) interest in applying recommended organisational changes in non-pandemic times.

Methods
Data from the German egePan GP survey (n = 516 GPs) - a multi-level clustered randomised web-based survey - were analysed. GPs’ interest in the future application of the eleven guideline recommendations was calculated. In addition, each recommendation was evaluated by the GPs using a Net-Promoter-Score (NPS range − 100 to 100). A linear regression model identified GP and practice characteristics associated with a higher interest in applying recommendations in non-pandemic times.

Results
98.5% of the GPs indicated the intention to implement at least one guideline recommendation prospectively: disinfectant dispensers at the entrance (86%), optimised consultation scheduling to reduce waiting times (83%), and glass screens in the reception area (72%), which also received the highest NPS scores. In contrast, lower interest was observed for items such as insurance card readers handled by patients (48%), only selected staff treating infectious patients (44%), and video consultations for patients with infections (26%). A higher interest to implement recommendations in non-pandemic times was associated with a higher crisis leadership score (p < 0.001), using the Corona-Warn-App (p = 0.007), and being a female GP (p = 0.045). In addition, GPs from Western, Northern, and Southern, and those with a higher patient volume per three months, were more interested in future implementation.

Conclusions
Overall, GPs demonstrated the readiness to follow the DEGAM COVID-19 guideline outside pandemic periods, establishing them as key contributors to pandemic preparedness in Germany.

Published: November 2024

Abstract
Background
The number of older adults with complex healthcare needs is growing alongside limited resources available in health services. To meet this challenge, it is urgent that healthcare staff are motivated and able to continuously translate new knowledge and working methods into daily practice. To facilitate such implementation, supportive measures responding to the healthcare personnel’s needs seem essential. The present study aims to translate, contextualize and test a Swedish version of the Implementation Process Assessment Tool (IPAT) for measuring the facilitation needs among staff implementing a new working process in municipal elderly care.

Methods
A mixed-method design was used. First, the existing instrument was translated into Swedish. Thereafter, twelve staff members with different professions working in healthcare and at the municipal elderly care were interviewed using Think-aloud interviews to contextualize and test the face validity of the translated instrument. Lastly, the adjusted instrument (Swe-IPAT) was psychometrically evaluated through a cross-sectional survey among 305 staff members working in municipal elderly care.

Results
The psychometric evaluation of the Swe-IPAT revealed satisfying properties. Three factors, largely in line with the original IPAT, are suggested. Internal consistency assessed using Cronbach’s alpha was 0.93 for the factor individual phases for behavioral change and perception of the intervention, 0.84 for the factor individual activities, and 0.95 for the factor collective readiness and support.

Conclusions
The 27-item Swe-IPAT, translated into Swedish and contextualized, demonstrated satisfactory psychometric properties when tested in an elderly care context. The instrument is suggested to be useful in providing feedback to managers in tailoring support and assessing implementation efforts among healthcare staff in elderly care. However, more research is needed to evaluate its properties throughout the entire implementation process and to test the usability of Swe-IPAT in other settings.

Abstract
Background
Recent reports from Thailand reveal a substantial surge in Plasmodium knowlesi cases over the past decades, with a more than eightfold increase in incidence by 2023 compared to 2018. This study investigates temporal changes in genetic polymorphism associated with the escalating transmission of P. knowlesi malaria in Thailand over time using the prominent vaccine candidate, pkmsp1 as a marker.

Methods
Twenty-five P. knowlesi samples collected in 2018–2023 were sequenced for the 42-kDa region of pkmsp1 and compared with 24 retrieved sequences in 2000–2009, focusing on nucleotide diversity, natural selection, recombination rate, and population differentiation.

Results
Seven unique haplotypes were identified in recent samples, compared to 15 in earlier samples. Nucleotide and haplotype diversity were lower in recent samples (π = 0.016, Hd = 0.817) than in earlier samples (π = 0.018, Hd = 0.942). Significantly higher synonymous substitution rates were observed in both sample sets (dS–dN = 2.77 and 2.43, p < 0.05), indicating purifying selection and reduced genetic diversity over time. Additionally, 8 out of 17 mutation points were located on predicted B-cell epitopes, suggesting an adaptive response by the parasites to evade immune recognition. Population differentiation analysis using the fixation index (Fst) revealed high genetic differentiation between parasite populations in central and southern Thailand or Malaysia. Conversely, the relatively lower Fst value between southern Thailand and Malaysia suggests a closer genetic relationship, possibly reflecting historical gene flow.

Conclusion
This study highlights a decline in genetic diversity and evidence of purifying selection associated with the recently increased incidence of P. knowlesi malaria in Thailand. The minor genetic differentiation between P. knowlesi populations from southern Thailand and Malaysia suggests a shared recent ancestry of these parasites and underscores the need for coordinated efforts between the two countries for the elimination of P. knowlesi.
Adipokines and their potential impacts on susceptibility to myocardial ischemia/reperfusion injury in diabetes

Published: November 2024

AbstractCoronary artery disease has a high mortality rate and is a striking public health concern, affecting a substantial portion of the global population. On the early onset of myocardial ischemia, thrombolytic therapy and coronary revascularization could promptly restore the bloodstream and nutrient supply to the ischemic tissue, efficiently preserving less severely injured myocardium. However, the abrupt re-establishment of blood flow triggers the significant discharge of previously accumulated oxidative substances and inflammatory cytokines, leading to further harm referred to as ischemia/reperfusion (I/R) injury. Diabetes significantly raises the vulnerability of the heart to I/R injury due to disrupted glucose and lipid processing, impaired insulin sensitivity and metabolic signaling, and increased inflammatory responses. Numerous studies have indicated that adipokines are crucial in the etiology and pathogenesis of obesity, diabetes, hyperlipidemia, hypertension, and coronary artery disease. Adipokines such as adiponectin, adipsin, visfatin, chemerin, omentin, and apelin, which possess protective properties against inflammatory activity and insulin resistance, have been shown to confer myocardial protection in conditions such as atherosclerosis, myocardial hypertrophy, myocardial I/R injury, and diabetic complications. On the other hand, adipokines such as leptin and resistin, known for their pro-inflammatory characteristics, have been linked to elevated cardiac lipid deposition, insulin resistance, and fibrosis. Meteorin-like (metrnl) exhibits opposite effects in various pathological conditions. However, the data on adipokines in myocardial I/R, especially in diabetes, is still incomplete and controversial. This review focuses on recent research regarding the categorization and function of adipokines in the heart muscle, and the identification of different signaling pathways involved in myocardial I/R injury under diabetic conditions, aiming to facilitate the exploration of therapeutic strategies against myocardial I/R injury in diabetes.
