Demographic history shapes North American gray wolf genomic diversity and informs species' conservation.

Effective population size estimates are critical information needed for evolutionary predictions and conservation decisions. This is particularly true for species with social factors that restrict access to breeding or experience repeated fluctuations in population size across generations. We investigated the genomic estimates of effective population size along with diversity, subdivision, and inbreeding from 162,109 minimally filtered and 81,595 statistically neutral and unlinked SNPs genotyped in 437 grey wolf samples from North America collected between 1986 and 2021. We found genetic structure across North America, represented by three distinct demographic histories of western, central, and eastern regions of the continent. Further, grey wolves in the northern Rocky Mountains have lower genomic diversity than wolves of the western Great Lakes and have declined over time. Effective population size estimates revealed the historical signatures of continental efforts of predator extermination, despite a quarter century of recovery efforts. We are the first to provide molecular estimates of effective population size across distinct grey wolf populations in North America, which ranged between Ne ~ 275 and 3050 since early 1980s. We provide data that inform managers regarding the status and importance of effective population size estimates for grey wolf conservation, which are on average 5.2-9.3% of census estimates for this species. We show that while grey wolves fall above minimum effective population sizes needed to avoid extinction due to inbreeding depression in the short term, they are below sizes predicted to be necessary to avoid long-term risk of extinction.

Impact of an evidence-based bundle on incontinence-associated dermatitis prevalence in hospital patients: A quasi-experimental translational study.

The study aimed to evaluate the effect of an intervention on the prevalence and severity of incontinence-associated dermatitis (IAD) in six hospitals in one state in Australia. This quasi-experimental pre-and post-study, conducted in 18 wards, was part of a larger implementation science study on incontinence-associated dermatitis. Skin and incontinence assessments were conducted on patients during February and March 2020 (pre-intervention) and July and August 2021 (post-intervention). The intervention comprised continence assessment and management, an education brochure for patients, family and caregivers on IAD, the Ghent Global IAD Categorisation Tool (GLOBIAD) and a skin care regime with patient skin protection measures (three-in-one barrier cream cloths, minimisation of bed protection layers, use of appropriate continence aid). A total of 1897 patients were assessed (pre-intervention = 964, post-intervention = 933). A total of 343 (35.6%) pre-intervention patients and 351 (37.6%) post-intervention patients had incontinence. The prevalence of hospital-acquired IAD was 6.71% in the pre-intervention group and 4.27% in the post-intervention group; a reduction of 36.3% (p = 0.159) despite higher patient acuity, prevalence of double incontinence and the COVID-19 pandemic in the post-intervention group compared with the pre-intervention group. Our multisite best practice IAD prevention and treatment intervention was able to reduce the prevalence and severity of hospital-acquired IAD, suggesting enduring effectiveness of the intervention.

Large carnivores avoid humans while prioritizing prey acquisition in anthropogenic areas.

Large carnivores are recovering in many landscapes where the human footprint is simultaneously growing. When carnivores encounter humans, the way they behave often changes, which may subsequently influence how they affect their prey. However, little research investigates the behavioural mechanisms underpinning carnivore response to humans. As a result, it is not clear how predator-prey interactions and their associated ecosystem processes will play out in the human-dominated areas into which carnivore populations are increasingly expanding. We hypothesized that humans would reduce predation risk for prey by disturbing carnivores or threatening their survival. Alternatively, or additionally, we hypothesized that humans would increase predation risk by providing forage resources that congregate herbivorous prey in predictable places and times. Using grey wolves Canis lupus in Jackson Hole, Wyoming, USA as a study species, we investigated 170 kill sites across a spectrum of human influences ranging from heavily restricted human activities on protected federal lands to largely unregulated activities on private lands. Then, we used conditional logistic regression to quantify how the probability of predation changed across varied types and amounts of human influences, while controlling for environmental characteristics and prey availability. Wolves primarily made kills in environmental terrain traps and where prey availability was high, but predation risk was significantly better explained with the inclusion of human influences than by environmental characteristics alone. Different human influences had different, and even converse, effects on the risk of wolf predation. For example, where prey were readily available, wolves preferentially killed animals far from motorized roads but close to unpaved trails. However, wolves responded less strongly to humans, if at all, where prey were scarce, suggesting they prioritized acquiring prey over avoiding human interactions. Overall, our work reveals that the effects of large carnivores on prey populations can vary considerably among different types of human influences, yet carnivores may not appreciably alter predatory behaviour in response to humans if prey are difficult to obtain. These results shed new light on the drivers of large carnivore behaviour in anthropogenic areas while improving understanding of predator-prey dynamics in and around the wildland-urban interface.

Fluoride Exposure in Community Prevention Programmes for Oral Health Using Nail Clippings and Spot Urine Samples: A Systematic Review and Meta-Analysis.

Due to practical difficulties in quantifying fluoride exposure in populations, practical and accurate biomarkers can play a major role in the surveillance of fluoride. Among different fluoride biomarkers, spot urine and nail clippings have gained more attention due to their ease of acquisition. However, there is no robust consensus about the accuracy of these biomarkers for the estimation of fluoride exposure. This systematic review and meta-analysis aimed to synthesise evidence on the association between fluoride exposure and the fluoride concentration of spot urine and nail clippings. This review was conducted and reported using the PRISMA Statement. Nine databases (Medline, CINAHL, Web of Science, Scopus, ScienceDirect, Sage Journals Online, Campbell Collaboration, Cochrane Collaboration, and Embase); search engines (Google and Google Scholar); and grey literature were searched up to September 2022. All screening, data extraction, and quality assessments were conducted in duplicate. All experimental and observational research studies that reported the correlation between fluoride exposure and fluoride concentrations of spot urine and/or nail clippings were included. The Mixed-Methods Appraisal tool was used to assess the methodological quality of the included studies. A random effect meta-analysis was carried out to determine the relationship between fluoride exposure and fluoride concentration of biomarkers (i.e., spot urine and nail clippings). Forty-four studies met the inclusion criteria. A total of 694,578 participants were included in this review. Twenty-five studies were included in the meta-analysis. The primary meta-analysis showed a moderate correlation of 0.674 (95% confidence interval [CI]: 0.623-0.725, n = 25) between fluoride intake and fluoride concentration of spot urine and a strong correlation of 0.938 (95% CI: 0.520-1.355, n = 11) between fluoride intake and the fluoride concentration of nail clippings in all age groups. The findings of secondary meta-analyses showed a strong positive correlation between fluoride intake and fluoride/creatinine ratio of spot urine in children (0.929; 95% CI: 0.502-0.991; n = 2). In conclusion, spot urine and nail clippings have the potential to be employed as non-invasively obtained biomarkers in populations. However, due to the scarcity of high quality, relevant studies, more research is needed to establish the validity of these biomarkers.

Mental illness stigmatisation among Malaysian adults: a systematic review.

BACKGROUND: Stigmatisation is considered a 'second illness' for people with a mental illness and is highly prevalent in Malaysia. Stigmatisation negatively impacts wellbeing, recovery and productivity. Addressing stigmatisation is integral towards people attaining a higher quality of life. AIM: To explore mental illness stigmatisation in Malaysian adults. METHOD: A systematic literature review was conducted using thematic analysis to synthesise and categorise evidence. Five key themes emerged, providing insight into mental health stigmatisation. FINDINGS: Cultural beliefs, limited knowledge of mental health and lack of education on mental health were factors influencing stigmatisation. Stigmatisation significantly affected the wellbeing and functioning of people with a mental illness. Interventions such as contact-based education effectively reduce stigmatising attitudes manifested by healthcare providers. CONCLUSION: Establishing mental health literacy, encouraging patient contact, promoting mental health awareness and strengthening mental health policies could reduce mental illness stigmatisation and its impact in Malaysia. Future research is warranted to investigate the impact on physical wellbeing and anti-stigmatising strategies targeting the general public.

Rapid upskilling about COVID-19 vaccines: an evaluation of a novel interprofessional education workshop.

BACKGROUND: An inter-professional education (IPE) workshop centred around newly approved COVID-19 vaccination was attended by 77 nursing and pharmacy students. AIM: To embed and evaluate the implementation of a virtual IPE workshop, and to upskill undergraduate nursing and pharmacy students about the COVID-19 vaccination. METHODS: The workshop was evaluated using a questionnaire completed by participants from both disciplines. A focus group was conducted with the IPE facilitators. RESULTS: 77 students out of a potential 400 attended the workshop (19% attendance). Of the 77 participants, 44 (23 nursing, 21 pharmacy) completed the questionnaire (57%), rating the content highly. There was overall positivity toward working interprofessionally, and there was no evidence of significant differences between how the two groups of students rated the workshop. Qualitative findings from students and facilitators corroborated the supposition that the workshop would enhance professional development. Thus, the workshop was successful in facilitating interprofessional interactions, with students all working collaboratively toward the same goal, the ultimate purpose of IPE. It was agreed that such an event should be included as part of the student curricula. CONCLUSION: Implementing an IPE event that includes real-time healthcare priorities can contribute to optimising students' healthcare education. More high-quality longitudinal research is needed to understand the impact of such sessions on students' competence and confidence.

Contrasting genetic trajectories of endangered and expanding red fox populations in the western U.S.

As anthropogenic disturbances continue to drive habitat loss and range contractions, the maintenance of evolutionary processes will increasingly require targeting measures to the population level, even for common and widespread species. Doing so requires detailed knowledge of population genetic structure, both to identify populations of conservation need and value, as well as to evaluate suitability of potential donor populations. We conducted a range-wide analysis of the genetic structure of red foxes in the contiguous western U.S., including a federally endangered distinct population segment of the Sierra Nevada subspecies, with the objectives of contextualizing field observations of relative scarcity in the Pacific mountains and increasing abundance in the cold desert basins of the Intermountain West. Using 31 autosomal microsatellites, along with mitochondrial and Y-chromosome markers, we found that populations of the Pacific mountains were isolated from one another and genetically depauperate (e.g., estimated Ne range = 3-9). In contrast, red foxes in the Intermountain regions showed relatively high connectivity and genetic diversity. Although most Intermountain red foxes carried indigenous western matrilines (78%) and patrilines (85%), the presence of nonindigenous haplotypes at lower elevations indicated admixture with fur-farm foxes and possibly expanding midcontinent populations as well. Our findings suggest that some Pacific mountain populations could likely benefit from increased connectivity (i.e., genetic rescue) but that nonnative admixture makes expanding populations in the Intermountain basins a non-ideal source. However, our results also suggest contact between Pacific mountain and Intermountain basin populations is likely to increase regardless, warranting consideration of risks and benefits of proactive measures to mitigate against unwanted effects of Intermountain gene flow.

Investigation into the predictive capability for mortality and the trigger points of the National Early Warning Score 2 (NEWS2) in emergency department patients.

INTRODUCTION: National Early Warning Score 2 (NEWS2) is widely used to monitor and trigger assessment throughout a patient's hospital journey. Since the development and role out of NEWS2, its ability to predict mortality has been assessed in several settings, although to date not within an undifferentiated ED population. METHODS: We conducted a retrospective observational study of all adult ED attendees at two EDs in Northern England, between March and November 2019. Multilevel multiple logistic regression analyses were conducted on patient episode data to assess the relationship between mortality at 2, 7 and 30 days from attendances; and maximum NEWS2, adjusting for age, sex, arrival mode and triage priority. RESULTS: Data were collected from 91 871 valid patient episodes associated with 64 760 patients. NEWS2 was a significant predictor of mortality at 2 days (OR 1.75; 95% CI 1.58 to 1.93); at 7 days (OR 1.69; 95% CI 1.59 to 1.80); at 30 days (OR 1.58; 95% CI 1.52 to 1.64). For the analyses of categorised NEWS2, NEWS2 of 2-20 was significantly associated with mortality at 2, 7 and 30 days compared with none assigned: OR 3.54 (95% CI 2.15 to 5.85) at 2 days; OR 6.05 (95% CI 3.92 to 9.34) at 7 days; OR 12.4 (95% CI 7.91 to 19.3) at 30 days. Increasing age, male sex, arrival by ambulance and higher triage categories were also associated with significantly increased mortality. Area under the receiver operating characteristic curve values of 0.963, 0.946 and 0.915, respectively, were recorded for mortality outcomes, with optimum likelihood ratios associated with a trigger of 4 NEWS2 points. CONCLUSIONS: NEWS2 is an effective predictor of mortality for patients presenting to the ED. Findings suggest that maximum NEWS2 of 4 and over may be the best trigger point for escalation of treatment. Findings also suggest a NEWS2 of 0-1 can identify a very low-risk group within the ED.

Sub-epidermal moisture assessment as a prompt for clinical action in treatment of pressure ulcers in at-risk hospital patients.

OBJECTIVE: This study assesses anonymous patient-level data on the use of sub-epidermal moisture (SEM) assessment technology as a tool in the prevention of pressure ulceration in at-risk hospital patients. METHOD: The relationship between technology-generated prompts for clinical action (patient turning, application of pressure redistributing equipment, heel protection or cream) and consequent clinical action was evaluated using data cross-tabulations (using data aggregated over multiple anatomical sites); in a multilevel model with patients clustered within wards, clustered in turn within hospitals, and controlling for additional patient- and institution-level factors; and using receiver operating characteristic (ROC) analyses of anatomy-specific data. The ability of the SEM assessment technology to detect deep and early-stage pressure ulcers/injuries on specific anatomical areas of a patient's body on admission, earlier than visual and tactile skin tissue assessments (STA), was assessed. RESULTS: A total of 15,574 patient assessments ('cases') were reported on 1995 patients. Most incidences of nurse action were in response to a prompt from SEM assessments (4944/5494; 90.0%). An SEM delta (Δ)≥0.6 resulted in nurse action in 4944/13,071 cases (37.8%). The multilevel model revealed strong evidence that SEM Δ prompts were significantly associated with nurse action (p<0.001; adjusted odds ratio: 1.99). CONCLUSION: In this study, SEM assessment technology effectively prompted nurse action moreso than skin reddening diagnosed via trained clinician judgement and STAs. While baseline responses of nurses' actions remained low, with or without SEM Δ prompts, findings verified the 'clinical utility' of SEM assessment technology as an objective prompt for early clinical action over and above existing mechanisms.

Sub-epidermal moisture assessment as an adjunct to visual assessment in the reduction of pressure ulcer incidence.

OBJECTIVE: To assess the effectiveness of sub-epidermal moisture (SEM) assessment technology as an adjunct to visual assessment to reduce pressure ulcer (PU) incidence alongside standard PU care pathways. METHOD: Data were obtained from wards located within 28 institutions in the UK, Canada, Belgium, Spain and Ireland. At each ward, the proportion of patients scanned who were observed to have one or more PUs of Category 2 or above during a pre-Pressure Ulcer Reduction Programme (PURP) implementation period starting between November 2017 and July 2018 was recorded. The proportion of patients scanned who were observed to have one or more PUs of Category 2 or above during a post-PURP implementation period starting between November 2018 and July 2019 was also recorded. A meta-analysis was conducted on the data using wards as the unit of analysis, to facilitate overall estimate of the PURP. A sensitivity study was also conducted to assess the sensitivity of results to data from specific institutions. RESULTS: A synthesised estimate of the overall relative risk (RR) was calculated to be 0.38 (95% confidence interval 0.26 to 0.56). Hence the risk of PU in the post-PURP cohort was about one-third that of the corresponding risk in the pre-PURP cohort. The sensitivity analysis revealed no evidence that any individual ward exerted excessive influence on the findings. CONCLUSION: The analysis has revealed strong evidence that implementation of the PURP was associated with reduction in incidence of Category 2 or above PUs across a wide range of clinical settings.

Antimicrobial stewardship in wound care implementation and measuring outcomes: results of an e-survey.

OBJECTIVE: Antimicrobial resistance (AMR) occurs (as a result of misuse, such as over-prescribing) when certain pathogens fail to respond to treatment with antimicrobials. Consequently, patients can become severely ill and possibly die. A strategy referred to as antimicrobial stewardship (AMS) has been introduced which reduces the impact of this antimicrobial misuse. To explore health professionals' (working in wound care, treating both acute and hard-to-heal wounds) position in terms of the following: awareness of AMS; if they are aware of AMS, if they implement procedures to support its practice; and if they implement AMS, do they measure its impact by and compare pre- and post-implementation? METHOD: An e-survey designed to explore health professionals' awareness of AMS and its implications for wound care. RESULTS: There were 987 respondents to the survey. The majority were specialist wound care nurses, mainly based in the UK or the US and Canada. A high proportion of those surveyed were completely/partially aware (35.1/57.9%, respectively) of AMS, and almost all implemented strategies to reduce antimicrobial prescribing. Of those surveyed, 36% took steps to measure the impact of AMS, and as a result 35.2% reported positive impacts (for example, cost reductions, a reduction in the systemic use of antimicrobials, a reduction in the topical use of antimicrobials and a reduced level of antimicrobial-resistant microorganisms). Challenging aspects of AMS implementation were reported by 33.2% of respondents (for example, poorer clinical outcomes in terms of healing and increased costs). The data highlighted that 40.49% felt that AMS would be 'easy' or 'very easy' to implement while 21.73% felt that AMS would be 'difficult' or 'very difficult' to implement. CONCLUSION: Education strategies need to be devised to raise awareness and support health professionals, including wound care practitioners, to understand and implement effective AMS programmes. Development of clear metrics is required to evaluate the effect of AMS programmes in clinical practice.

Antimicrobial stewardship: a JWC Masterclass.

This paper presents an overview of a Journal of Wound Care (JWC) webinar 'Antimicrobial Stewardship Masterclass' which took place on 17 June 2021, bringing together international experts in the field of wound care. The webinar was undertaken to provide an educational platform elucidating the basis of an effective antimicrobial strategy in wound care, and to demonstrate how it impacts on wound care clinicians and their day-to-day practice, using examples of 'real-life' patient outcomes.

Assessment of energy and nutrient intakes among undergraduate students attending a University in the North of England.

Background: Unhealthy diets are typical of university students and are often thought to be unrepresentative of the general population. The main aim was to determine the energy and nutrient intakes of a large cohort of undergraduate university students; and to compare to gender-specific dietary reference values (DRVs) and nutrient data from the general population. Methodology: Data was collected from 639 university students aged 18-24 years who completed 4-day diet diaries. The energy and nutrient intake was determined and percentage energy values calculated and compared with dietary reference values (DRVs) and the National Diet and Nutrition Survey (NDNS) and Family Food Statistics. Logistic regression methods were used to identify micronutrients functioning as predictors of exceeding DRVs. Results: Energy intakes were lower than the DRV. The percentage total energy values for protein, fat, saturated fat and carbohydrate exceeded DRVs but the percentage energy from alcohol was below the maximum 5%. The DRVs were met for vitamin C, thiamin, and sodium/salt. Iron and calcium intakes were met in males but not in females. Intakes for fibre and vitamin A were below the DRV. Student data was comparable to the NDNS, with the exception of alcohol, fibre, vitamin A, calcium and sodium/salt, which were all lower than the NDNS. Conclusions: This study contradicts the stereotypical assumption that students are following a high energy, fat, saturated fat, total sugars, salt and alcohol diet compared with the general population.

Development and Psychometric Testing of a Knowledge Instrument on Incontinence-Associated Dermatitis for Clinicians: The Know-IAD.

PURPOSE: The purpose of this study was to describe the development and evaluation of the psychometric properties of an instrument used to assess clinician knowledge of Incontinence-associated dermatitis (IAD). DESIGN: The instrument was developed in three phases: Phase 1 involved item development; Phase 2 evaluated content validity of the instrument by surveying clinicians and stakeholders within a single state of Australia and, Phase 3 used a pilot multisite cross-sectional survey design to determine composite reliability and evaluate scores of the knowledge tool. SUBJECTS AND SETTINGS: In Phase 1, the instrument was developed by five persons with clinical and research subject expertise in the area of IAD. In Phase 2, content validity was evaluated by a group of 13 clinicians (nurses, physicians, occupational therapists, dietitians, and physiotherapists) working in acute care across one Australian state, New South Wales, along with two consumer representatives. In Phase 3, clinicians, working across six hospitals in New South Wales and on wards with patients diagnosed with incontinence-associated dermatitis, participated in pilot-testing the instrument. METHODS: During Phase 1, a group of local and international experts developed items for a draft tool based on an international consensus document, our prior research evaluating incontinence-associated dermatitis knowledge, and agreement among an expert panel of clinicians and researchers. Phase 2 used a survey design to determine content validity of the knowledge tool. Specifically, we calculated item- and scale-level content validity ratios and content validity indices for all questions within the draft instrument. Phase 3 comprised pilot-testing of the knowledge tool using a cross-sectional survey. Analysis involved confirmatory factor analysis to confirm the hypothesized model structure of the knowledge tool, as measured by model goodness-of-fit. Composite reliability testing was undertaken to determine the extent of internal consistency between constituent items of each construct. RESULTS: During Phase 1, a draft version of the Barakat-Johnson Incontinence-Associated Dermatitis Knowledge tool (Know-IAD), comprising 19 items and divided into three domains of IAD-related knowledge: 1) Etiology and Risk, 2) Classification and Diagnosis, and 3) Prevention and Management was developed. In Phase 2, 18 of the 19 items demonstrated high scale content validity ratios scores on relevance (0.75) and clarity (0.82); and high scale-content validity indices scores on relevance (0.87) and clarity (0.91). In Phase 3, the final 18-item Know-IAD tool demonstrated construct validity by a model goodness-of-fit. Construct validity was excellent for the Etiology and Risk domain (root mean squared error=0.02) and Prevention and Management domain (root mean squared error=0.02); it was good for the Classification and Diagnosis domain (root mean squared error=0.04). Composite reliability (CR) was good in the Etiology and Risk domain (CR=0.76), Prevention and Management domains (CR=0.75), and adequate in the Classification and Diagnosis domain (CR=0.64). Respondents had good understanding of etiology and risk (72.6% correct responses); fairly good understanding of prevention and management of IAD (64.0% correct responses) and moderate understanding of classification and diagnosis (40.2% correct responses). CONCLUSIONS: The Know-IAD demonstrated good psychometric properties and provides preliminary evidence that it can be applied to evaluate clinician knowledge on IAD.

Clinician Knowledge of Incontinence-Associated Dermatitis: A Multisite Survey of Healthcare Professionals in Acute and Subacute Settings.

PURPOSE: This study examined clinicians' knowledge of incontinence-associated dermatitis (IAD) using the Barakat-Johnson Incontinence-Associated Dermatitis Knowledge Tool (Know-IAD). DESIGN: A cross-sectional multicenter survey. SUBJECTS AND SETTING: The setting was 6 hospitals across 5 health districts in New South Wales, Australia. The participants were nurses (registered nurses and enrolled nurses), physicians, allied health (occupational therapists, dietitians, and physiotherapists), and students (nursing and allied health). METHODS: Data about IAD knowledge were collected from November 2019 to January 2020. The Know-IAD, an 18-item validated instrument that measures knowledge of IAD in 3 domains (etiology and risk, classification and diagnosis, and prevention and management), was administered to a cross section of eligible clinicians. The participants anonymously completed hard copy surveys. Descriptive and exploratory analyses were conducted to quantify clinicians' knowledge about the etiology and risk, classification and diagnosis, and prevention and management of IAD. A mean knowledge score of 70% was considered to be satisfactory. RESULTS: Four hundred twelve respondents completed the survey. One hundred twenty nine respondents (31.3%) achieved 70% correct responses and greater for the entire set of items. For the etiology and risk domain, 348 respondents (84.5%) obtained a score of 70% correct responses and greater, 67 respondents (16.3%) achieved 70% correct responses and greater for the classification and diagnosis domain, and 84 respondents (20.4%) achieved 70% correct responses and greater for the prevention and management domain. CONCLUSION: Clinicians tend to have low knowledge and recognition of IAD, particularly in the areas of classification and diagnosis along with prevention and management. They tend to have higher knowledge of how IAD is caused and the risk factors. This study has identified knowledge gaps for further education that can improve assessment, prevention, and management of IAD.

Complex Foot Infection Treated With Surgical Debridement and Antibiotic Loaded Calcium Sulfate-A Retrospective Cohort Study of 137 Cases.

Complex foot infections involving bone and soft tissue in patients with co-morbidities such as diabetes and peripheral arterial disease (PAD) are a cause of significant hospital admission. They are associated with substantial economic costs to health services worldwide. Historically, severe foot infection has been treated with surgical debridement and prolonged courses of systemic antibiotics. Prolonged systemic antibiotic use increases the risk of drug side effects, antimicrobial resistance and Clostridium difficile infection. The purpose of this study was to investigate whether surgical debridement and implantation of antibiotic loaded calcium sulfate is effective in the resolution of foot infection and wound healing. A retrospective cohort study of 137 consecutive cases of osteomyelitis (127) or significant soft tissue infection (10) over 62 months from 02/2013 to 04/2018 was conducted following local ethical approval. All cases of infection were treated with surgical debridement and local antibiotic-loaded calcium sulfate. The primary outcomes of infection resolution, time to healing and duration of postoperative antibiotics were measured. In 137 cases, 88.3% of infections resolved. Infection was eradicated in 22 patients without postoperative systemic antibiotics. About 82.5% of wounds healed, with an average healing time of 11.3 weeks. Healing time was significantly increased for the co-morbidities of diabetes and PAD (p =< .05) and for those requiring prolonged systemic postoperative antibiotics. Conservative surgical debridement and implantation of local antibiotic impregnated calcium sulfate is safe and effective in managing complex foot infections. We advocate early surgical intervention before deeper tissue involvement to help preserve lower limb structure and function.

The viability and acceptability of a Virtual Wound Care Command Centre in Australia.

The objective of this study was to assess the viability and acceptability of an innovative Virtual Wound Care Command Centre where patients in the community, and their treating clinicians, have access to an expert wound specialist service that comprises a digitally enabled application for wound analysis, decision-making, remote consultation, and monitoring. Fifty-one patients with chronic wounds from 9 centres, encompassing hospital services, outpatient clinics, and community nurses in one metropolitan and rural state in Australia, were enrolled and a total of 61 wounds were analysed over 7 months. Patients received, on average, an occasion of service every 4.4 days, with direct queries responded to in a median time of 1.5 hours. During the study period, 26 (42.6%) wounds were healed, with a median time to healing of 66 (95% CI: 56-88) days. All patients reported high satisfaction with their wound care, 86.4% of patients recommended the Virtual Wound Care Command Centre with 84.1% of patients reporting the digital wound application as easy to use. Potential mean travel savings of $99.65 for rural patients per visit were recognised. The data revealed that the Virtual Wound Care Command Centre was a viable and acceptable patient-centred expert wound consultation service for chronic wound patients in the community.

Health facility preparedness of maternal and neonatal health services: a survey in Jumla, Nepal.

BACKGROUND: Over the past 20 years, Nepal has seen major improvements in childhood and maternal survival. In 2015, the Nepalese government introduced a new federal political structure. It is unclear how this has affected the health system, and particularly, maternal and child health care. Hence, this study aims to describe and analyse health facility preparedness in the light of the federalization process with regards to providing appropriate and timely maternal and neonatal health services. METHODS: A descriptive cross-sectional study was conducted in Jumla district, Nepal in 2019 covering all 31 state health facilities (HF) to assess the availability of maternal and neonatal health services including appropriate workforce and access to essential medicines. Tests of association between demographic factors and the probability of a facility experiencing a shortage of essential medicine within the last 3 months were also conducted as exploratory procedures. RESULTS: Out ot 31 HFs, more than 90% of them had all their staff positions filled. Most facilities (n = 21) had experienced shortages of essential medicines within the past 3 months. The most common out of stock medicine were: Amoxicillin (n = 10); paracetamol (n = 10); Vitamin A (n = 7); and Metronidazole (n = 5). Twenty-two HFs had referred maternal and newborn cases to a higher centre within the past 12 months. However, more worryingly, twenty HFs or their catchment communities did not have emergency ambulance transport for women and newborns. CONCLUSION: HFs reported better staffing levels than levels of available drugs. HFs should be supported to meet required minimal standards such as availability of essential medicines and the provision of emergency ambulance transport for women and newborns.

Influence of Sprint Duration during Minimal Volume Exercise on Aerobic Capacity and Affect.

The aims of this study were to investigate the influence of reduced-exertion, high-intensity interval training (REHIT), comparing a novel shortened-sprint protocol (SSREHIT) against a traditional protocol (TREHIT), on perceptual responses and to determine if changes in peak oxygen uptake (V˙O2peak) are attenuated with shorter sprints. Twenty-four healthy men undertook 15 sessions of SSREHIT or TREHIT. V˙O2peak was determined at baseline and after completion of each exercise condition. Affective (pleasure-displeasure) responses and perceived exertion were assessed during exercise to capture peak responses. Enjoyment was recorded 5-min after cessation of exercise. Compared to baseline, V˙O2peak increased in both groups (6% for SSREHIT [d=- 0.36] and 9% for TREHIT [d=- 0.53], p=0.01). Affective responses were more favourable for SSREHIT (p=0.001, d=1.62), but both protocols avoided large negative peaks of displeasure. Peak ratings of perceived exertion were lower for SSREHIT (p=0.001, d=- 1.71), although there were no differences in enjoyment (d=0.25). The results demonstrate both exercise conditions can increase V˙O2peak without overly compromising perceptual responses. Decreased sprint duration might further circumvent negative perceptual responses but might also attenuate physiological adaptations.

Using past performance to improve future clinical outcomes in pressure ulcer prevention.

OBJECTIVE: Episodes of inpatient care-related pressure ulcers (PU) lead to deleterious effects on patient quality of life, and additional costs associated with wound dressings, staff visits and hospitalisation. Accurate prediction of future incidence may be helpful in defining strategies for benchmarking and resource management. Observations of category 2 or above PUs during episodes of care at an NHS Foundation Trust were recorded monthly from 2010 to 2020. Trust-specific interventions designed to reduce PU incidence, such as procurement of specialised staff and equipment, were also recorded. This study aimed to investigate the historical pattern of PU incidence in the Trust to assess intervention effectiveness in reducing PU incidence, and to use historical data to derive estimates of future incidence. METHOD: Time-series analysis was conducted on monthly PU incidence data to quantify underlying trends, seasonality and effect of interventions, and to derive a suitable model to predict future incidence levels. RESULTS: Mean monthly PU incidence gradually reduced from 20.3 during 2012 to 5.08 during 2019; with a negative linear trend in the presence of concurrent seasonal effects. There was limited evidence that implementation of specific interventions was associated with raised rates of reduction; however, incidence reductions during intervention periods continued from lower baselines. Best estimate predictions revealed that incidence is likely to stay at current levels or below for the foreseeable future. CONCLUSION: Past data can be used to model future episodes of inpatient care PU occurrence. Interventions may be effective in reducing PU incidence rates.
