Clinical evaluation of a fully electronic microfluidic white blood cell analyzer

by Jianye Sui, Zhongtian Lin, Shahriar Azizpour, Fei Chen, Sunanda Gaur, Kelly Keene, Farzad Soleimani, Tanaya Bhowmick, Zubaid Rafique, Mehdi Javanmard

The White Blood Cell (WBC) count is one of the key parameters signaling the health of the immune system. Abnormal WBC counts often signal a systemic insult to the body such as an underlying infection or an adverse side effect to medication. Typically, the blood collected is sent to a central lab for testing, and results come back within hours, which is often inconvenient and may delay time-sensitive diagnosis or treatment. Here, we present the CytoTracker, a fully electronic, microfluidic based instant WBC analyzer with the potential to be used at point-of-care. The CytoTracker is a lightweight, portable, affordable platform capable of quantifying WBCs within minutes using only 50 μl of blood (approximately one drop of blood). In this study, we clinically evaluated the accuracy and performance of CytoTracker in measuring WBC and granulocyte counts. A total of 210 adult patients were recruited in the study. We validated the CytoTracker against a standard benchtop analyzer (Horiba Point of Care Hematology Analyzer, ABX Micros 60). Linear dynamic ranges of 2.5 k/μl– 35 k/μl and 0.6 k/μl– 26 k/μl were achieved for total WBC count and granulocyte count with correlation coefficients of 0.97 and 0.98. In addition, we verified CytoTracker’s capability of identifying abnormal blood counts with above 90% sensitivity and specificity. The promising results of this clinical validation study demonstrate the potential for the use of the CytoTracker as a reliable and accurate point-of-care WBC analyzer.

Evaluating the efficacy of recombinant human growth factors in scar remodelling for patients with facial soft tissue injuries

Abstract

Facial soft tissue injuries, often resulting in scarring, pose a challenge in reconstructive and aesthetic surgery due to the need for functional and aesthetic restoration. This study evaluates the efficacy of recombinant human growth factors (rhGFs) in scar remodelling for such injuries. A retrospective evaluation was conducted from January 2020 to January 2023, involving 100 patients with facial soft tissue injuries. Participants were divided equally into a control group, receiving standard cosmetic surgical repair, and an observation group, treated with rhGFs supplemented cosmetic surgery. The study assessed scar characteristics (pigmentation, pliability, vascularity, height), hospital stay duration, tissue healing time, complication rates and patient satisfaction. The observation group demonstrated significant improvements in all scar characteristics, with notably better pigmentation, pliability, vascularity and height compared with the control group. The rhGF treatment also resulted in reduced hospital stay duration and faster tissue healing. Notably, the total complication rate was significantly lower in the observation group (10%) compared with the control group (34%). Additionally, patient satisfaction levels were higher in the observation group, with 98% combined satisfaction compared with 76% in the control group. The application of rhGFs in treating facial soft tissue injuries significantly enhances scar remodelling, expedites healing, reduces complications and improves patient satisfaction. These findings establish rhGFs as a valuable tool in the management of facial soft tissue injuries, highlighting their potential in improving both functional and aesthetic outcomes.

Use of removable support boot versus cast for early mobilisation after ankle fracture surgery: cost-effectiveness analysis and qualitative findings of the Ankle Recovery Trial (ART)

Por: Baji · P. · Barbosa · E. C. · Heaslip · V. · Sangar · B. · Tbaily · L. · Martin · R. · Docherty · S. · Allen · H. · Hayward · C. · Marques · E. M. R.
Objectives

To estimate the cost-effectiveness of using a removable boot versus a cast following ankle fracture from the National Health Service and Personal Social Services (NHS+PSS) payer and societal perspectives and explore the impact of both treatments on participants’ activities of daily living.

Design

Cost-effectiveness analyses and qualitative interviews performed alongside a pragmatic multicentre randomised controlled trial.

Setting

Eight UK NHS secondary care trusts.

Participants

243 participants (60.5% female, on average 48.2 years of age (SD 16.4)) with ankle fracture. Qualitative interviews with 16 participants. Interventions removable air boot versus plaster cast 2 weeks after surgery weight bearing as able with group-specific exercises.

Primary and secondary outcome measures

Quality-adjusted life years (QALYs) estimated from the EQ-5D-5L questionnaire, costs and incremental net monetary benefit statistics measured 12 weeks after surgery, for a society willing-to-pay £20 000 per QALY.

Results

Care in the boot group cost, on average, £88 (95% CI £22 to £155) per patient more than in the plaster group from the NHS+PSS perspective. When including all societal costs, the boot saved, on average, £676 per patient (95% CI –£337 to £1689). Although there was no evidence of a QALY difference between the groups (–0.0020 (95% CI –0.0067 to 0.0026)), the qualitative findings suggest participants felt the boot enhanced their quality of life. Patients in the boot felt more independent and empowered to take on family responsibilities and social activities.

Conclusions

While the removable boot is slightly more expensive than plaster cast for the NHS+PSS payer at 12 weeks after surgery, it reduces productivity losses and the need for informal care while empowering patients. Given that differences in QALYs and costs to the NHS are small, the decision to use a boot or plaster following ankle surgery could be left to patients’ and clinicians’ preferences.

Introduction

Wearing masks has proven beneficial in preventing respiratory pathogen infections in individuals with chronic obstructive pulmonary disease (COPD). However, the impact of different mask types on physiological indicators and daily physical activity in COPD patients remains uncertain. This study aims to assess the immediate effects of various mask types on cardiopulmonary function indicators, subjective perceptions and the 6-minute walking distance (6MWD) in individuals with COPD.

Methods and analysis

This randomised controlled trial will enrol 129 stable COPD patients. Participants will be randomly divided into three groups: control, N95 mask and surgical mask groups. Each group will undergo both a 6-minute seated test and a 6-minute walk test (6MWT), without or with their respective masks. A 10-minute interval will be provided between the two phases. The primary indicators of the study include the 6MWD and blood oxygen saturation. Secondary outcomes encompass blood pressure, pulse rate, Borg score, Rate of Perceived Exertion (RPE) score and subjective perception score. Oxygen saturation, pulse rate and blood pressure will be recorded four times during the trial, while Borg and RPE scores will be compared before and after the 6MWT. Additionally, subjective perception scores will be collected after each mask-wearing stage.

Ethics and dissemination

This study has received approval from the Ethics Committee of the Affiliated Hospital of Gansu University of Chinese Medicine (approval number: 202335). We plan to disseminate research results through publication in a peer-reviewed journal or presentation at a conference.

Longitudinal study of changes observed in quality of life, psychological state cognition and pulmonary and functional capacity after COVID‐19 infection: A six‐ to seven‐month prospective cohort

Abstract

Aims

To investigate the health-related quality of life (HRQoL), symptoms, psychological and cognitive state and pulmonary and physical function of nonhospitalised COVID-19 patients at long-term, and to identify factors to predict a poor HRQoL in this follow-up.

Background

Studies have focused on persistent symptoms of hospitalised COVID-19 patients in the medium term. Thus, long-term studies of nonhospitalised patients are urgently required.

Design

A longitudinal cohort study.

Methods

In 102 nonhospitalised COVID-19 patients, we collected symptoms at 3 months (baseline) and at 6–7 months (follow-up) from diagnosis (dyspnoea, fatigue/muscle weakness and chest/joint pain), HRQoL, psychological state, cognitive function, pulmonary and physical function. This study adhered to the STROBE statement.

Results

HRQoL was impaired in almost 60% of the sample and remained impaired 6–7 months. At 3 months, more than 60% had impaired physical function (fatigue/muscle weakness and reduced leg and inspiratory muscle strength). About 40%–56% of the sample showed an altered psychological state (post-traumatic stress disorder (PTSD), anxiety/depression), cognitive function impairment and dyspnoea. At 6–7-months, only a slight improvement in dyspnoea and physical and cognitive function was observed, with a very high proportion of the sample (29%–55%) remained impaired. Impaired HRQoL at 6–7 months was predicted with 82.4% accuracy (86.7% sensitivity and 83.3% specificity) by the presence at 3 months of muscle fatigue/muscle weakness (OR = 5.7 (1.8–18.1)), PTSD (OR = 6.0 (1.7–20.7)) and impaired HRQoL (OR = 11.7 (3.7–36.8)).

Conclusion

A high proportion of nonhospitalised patients with COVID-19 experience an impaired HRQoL, cognitive and psychological function at long-term. HRQoL, PTSD and dyspnoea at 3 months can identify the majority of patients with COVID-19 who will have impaired quality of life at long-term.

Relevance to clinical practice

Treatments aimed at improving psychological state and reducing the fatigue/muscle weakness of post-COVID-19 patients could be necessary to prevent the patients’ HRQoL from being impaired at 6–7 months after their reported recovery.

Service readiness for the management of non-communicable diseases in publicly financed facilities in Malawi: findings from the 2019 Harmonised Health Facility Assessment census survey

Por: Ahmed · S. · Cao · Y. · Wang · Z. · Coates · M. M. · Twea · P. · Ma · M. · Chiwanda Banda · J. · Wroe · E. · Bai · L. · Watkins · D. A. · Su · Y.
Introduction

Non-communicable diseases (NCDs) are rising in low-income and middle-income countries, including Malawi. To inform policy-makers and planners on the preparedness of the Malawian healthcare system to respond to NCDs, we estimated NCD service readiness in publicly financed healthcare facilities in Malawi.

Methods

We analysed data from 564 facilities surveyed in the 2019 Harmonised Health Facility Assessment, including 512 primary healthcare (PHC) and 52 secondary and tertiary care (STC) facilities. To characterise service readiness, applying the law of minimum, we estimated the percentage of facilities with functional equipment and unexpired medicines required to provide NCD services. Further, we estimated permanently unavailable items to identify service readiness bottlenecks.

Results

Fewer than 40% of PHC facilities were ready to deliver services for each of the 14 NCDs analysed. Insulin and beclomethasone inhalers had the lowest stock levels at PHC facilities (6% and 8%, respectively). Only 17% of rural and community hospitals (RCHs) have liver and kidney diagnostics. STC facilities had varying service readiness, ranging from 27% for managing acute diabetes complications to 94% for chronic type 2 diabetes management. Only 38% of STC facilities were ready to manage chronic heart failure. Oral pain medicines were widely available at all levels of health facilities; however, only 22% of RCHs and 29% of STCs had injectable morphine or pethidine. Beclomethasone was never available at 74% of PHC and 29% of STC facilities.

Conclusion

Publicly financed facilities in Malawi are generally unprepared to provide NCD services, especially at the PHC level. Targeted investments in PHC can substantially improve service readiness for chronic NCD conditions in local communities and enable STC to respond to acute NCD complications and more complex NCD cases.

Exploring the impact of TGF‐β family gene mutations and expression on skin wound healing and tissue repair

Abstract

Transforming Growth Factor-Beta (TGF-β) signalling pathway is of paramount importance in the processes of wound healing, epidermal integrity maintenance and development of skin cancer. The objective of this research endeavour was to clarify the impact of gene mutations and variations in expression within TGF-β family on mechanisms of tissue repair, as well as to identify potential targets for therapeutic purposes in non-melanoma skin cancer (NMSC). The methods utilized in this study involved obtaining RNA-seq data from 224 NMSC patients and paired normal skin tissues from the PRJNA320473 and PRJEB27606 databases. The purpose of the differential gene expression analysis was to identify genes whose expression had changed significantly. In order to evaluate the effects and interrelationships of identified gene variants, structural analysis with AlphaFold and PDB data and network analysis with the STRING database were both utilized. Critical gene expression was externally validated through the utilization of the GEPIA database. Tumour tissues exhibited a notable upregulation of genes associated with the TGF-β pathway, specifically MMP1, MMP3, MMP9, EGF, COL3A1 and COL1A2, in comparison with normal tissues. As indicated by the central node status of these genes in the network analysis, they play a crucial role in the progression of NMSCs. The results of the structural analysis suggested that mutations might cause functional disruptions. External validation of the upregulation confirmed the expression trends and emphasized the biomarker potential of the upregulated genes. In conclusion, this research offered thorough examination of molecular modifications that occur in TGF-β family genes, which are linked to cutaneous wound healing and NMSC. The modified expression of the identified hub genes may represent innovative targets for therapeutic intervention.

Prevalence and correlates of tetanus toxoid uptake among women in sub-Saharan Africa: Multilevel analysis of demographic and health survey data

by Richard Gyan Aboagye, Hubert Amu, Robert Kokou Dowou, Promise Bansah, Ijeoma Omosede Oaikhena, Luchuo Engelbert Bain

Background

Tetanus toxoid vaccination is one of the most effective and protective measures against tetanus deaths among mothers and their newborns. We examined the prevalence and correlates of tetanus toxoid uptake among women in sub-Saharan African (SSA).

Materials and methods

We analysed pooled data from the Demographic and Health Surveys (DHS) of 32 countries in SSA conducted from 2010 to 2020. We included 223,594 women with a history of childbirth before the survey. Percentages were used to present the prevalence of tetanus toxoid vaccine uptake among the women. We examined the correlates of tetanus toxoid uptake using a multilevel binary logistic regression.

Results

The overall prevalence of tetanus toxoid uptake was 51.5%, which ranged from 27.5% in Zambia to 79.2% in Liberia. Women age, education level, current working status, parity, antenatal care visits, mass media exposure, wealth index, and place of residence were the factors associated with the uptake of tetanus toxoid among the women.

Conclusion

Uptake of tetanus toxoid vaccination among the women in SSA was low. Maternal age, education, current working status, parity, antenatal care visits, exposure to mass media, and wealth status influence tetanus toxoid uptake among women. Our findings suggest that health sector stakeholders in SSA must implement interventions that encourage pregnant women to have at least four antenatal care visits. Also, health policymakers in SSA could ensure that the tetanus toxoid vaccine is free or covered under national health insurance to make it easier for women from poorer households to have access to it when necessary.

Association between the number of retrieved lymph nodes and demographic/tumour-related characteristics in colorectal cancer: a systematic review and meta-analysis

Por: Liu · Q. · Huang · M. · Yang · J. · Jiang · M. · Zhao · Z. · Zhao · H. · He · T. · Bai · Y. · Zhang · R. · Zhang · M.
Objective

Clinical practice guidelines recommend retrieving at least 12 lymph nodes for correct staging in colorectal cancer. However, it is difficult to retrieve adequate lymph nodes because of various factors. We aimed to evaluate the association between the number of retrieved lymph nodes and demographic/tumour-related characteristics in colorectal cancer.

Design

Systematic review and meta-analysis of primary studies.

Data sources

PubMed, Embase, Cochrane and Web of Science were searched from January 2016 to June 2023.

Eligibility criteria for selecting studies

Studies that evaluated the association between retrieved lymph nodes and demographic/tumour-related characteristics in colorectal cancer were included.

Data extraction and synthesis

OR with 95% conference intervals was extracted and pooled.

Results

A total of 54 studies containing 2 05 821 patients were included in this meta-analysis. The results showed that fewer nodes were retrieved from elderly patients (OR=0.70, 95% CI (0.54 to 0.90), p=0.005), and from tumours located in the left colon than in the right colon (OR=0.43, 95% CI (0.33 to 0.56), p

Conclusions

The study results suggest that clinicians have an increased opportunity to retrieve sufficient lymph nodes for accurate pathological staging to guide treatment decisions in patients with colorectal cancer who are young, female, with tumours located in the right colon, advanced T stage and N2 stage.

Can phone surveys be representative in low- and middle-income countries? An application to Myanmar

by Isabel Lambrecht, Joanna van Asselt, Derek Headey, Bart Minten, Patrick Meza, Moe Sabai, Thet Su Sun, Hnin Ei Win

For decades, in-person data collection has been the standard modality for nationally and sub-nationally representative socio-economic survey data in low- and middle-income countries. As the COVID-19 pandemic rendered in-person surveys impossible and unethical, the urgent need for rapid monitoring necessitated researchers and statistical agencies to turn to phone surveys. However, apart from pandemic-related factors, a variety of other reasons can render large segments of a population inaccessible for in-person surveys, including political instability, climatic shocks, and remoteness. Such circumstances currently prevail in Myanmar, a country facing civil conflict and political instability since the February 2021 military takeover. Moreover, Myanmar routinely experiences extreme weather events and is characterized by numerous inaccessible and remote regions due to its mountainous geography. We describe a novel approach to sample design and statistical weighting that has been successfully applied in Myanmar to obtain nationally and sub-nationally representative phone survey data. We use quota sampling and entropy weighting to obtain a better geographical distribution compared to recent in-person survey efforts, including reaching respondents in areas of active conflict. Moreover, we minimize biases towards certain household and respondent characteristics that are usually present in phone surveys, for example towards well-educated or wealthy households, or towards men or household heads as respondents. Finally, due to the rapidly changing political and economic situation in Myanmar in 2022, the need for frequent and swift monitoring was critical. We carried out our phone survey over four quarters in 2022, interviewing more than 12,000 respondents in less than three months each survey. A survey of this scale and pace, though generally of much shorter duration than in-person interviews, could only be possible on the phone. Our study proves the feasibility of collecting nationally and sub nationally representative phone survey data using a non-representative sample frame, which is critical for rapid monitoring in any volatile economy.

Objectives

The Self-Management Analysis in Chronic Conditions (SMACC) checklist was developed as a guidance tool to support the development, comparison and evaluation of self-management support programmes for persons with a chronic condition. The checklist was based on a previously performed concept analysis of self-management. The aim of this study was to validate its content using an international Delphi study and to deliver a final version.

Design

A two-round Delphi study was conducted between October 2022 and January 2023. Using the researchers’ networks, professionals with research or clinical expertise in self-management support and chronic conditions were recruited via online purposive snowball sampling. Participants were asked to score each item of the checklist (16 items total) on 3 content validity indicators: (1) clarity and comprehensibility, (2) relevance and importance and (3) degree of alignment with the overall goal of the checklist to promote adequate and comprehensive self-management support programmes. A consensus threshold of 75% agreement was used. The participants were also asked general questions about the checklist as a whole and were asked to provide feedback considering its refinement.

Results

Fifty-four professionals with an average 14.5 years of experience participated in round 1, 48 with an average 12.5 years of experience participated in round 2. The majority of professionals were from Western Europe. For the majority of items consensus was reached after round 1. In round 2, 3 of the 4 remaining items reached consensus, 1 last item was retained based on highly recurring feedback.

Conclusions

The SMACC checklist was considered a valid and comprehensive tool to aid the development, evaluation and comparison of self-management support programmes. It was acknowledged as a useful instrument to supplement existing frameworks and was seen as feasible to implement in both research and clinical settings. Further validation in the field, with input from patients and peer experts, will be valuable.

An examination of retracted articles in nursing literature

Abstract

Introduction

The output of scholarly publications in scientific literature has increased exponentially in recent years. This increase in literature has been accompanied by an increase in retractions. Although some of these may be attributed to publishing errors, many are the result of unsavory research practices. The purposes of this study were to identify the number of retracted articles in nursing and reasons for the retractions, analyze the retraction notices, and determine the length of time for an article in nursing to be retracted.

Design

This was an exploratory study.

Methods

A search of PubMed/MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, and Retraction Watch databases was conducted to identify retracted articles in nursing and their retraction notices.

Results

Between 1997 and 2022, 123 articles published in the nursing literature were retracted. Ten different reasons for retraction were used to categorize these articles with one-third of the retractions (n = 37, 30.1%) not specifying a reason. Sixty-eight percent (n = 77) were retracted because of an actual or a potential ethical concern: duplicate publication, data issues, plagiarism, authorship issues, and copyright.

Conclusion

Nurses rely on nursing-specific scholarly literature as evidence for clinical decisions. The findings demonstrated that retractions are increasing within published nursing literature. In addition, it was evident that retraction notices do not prevent previously published work from being cited. This study addressed a gap in knowledge about article retractions specific to nursing.

Introduction

One in six people live with disability in Australia with higher levels of disability of people from diverse communities, such as those with culturally and linguistically diverse (CALD) backgrounds. In Australia, CALD refers to people from diverse ethnicity and cultures, nationalities, societal structures and religions that may or may not speak a language other than English. This study employs researchers with lived experience of disability and peer support to study the impact of peer support for people with disability, including people from CALD backgrounds, in two peer-led organisations in New South Wales (NSW) Australia.

Methods and analysis

This study uses participatory action research and inclusive research design with researchers with lived experience, having lived experience of disability and a peer in the disability community, leading the research.

Over three years, three different groups will be recruited through Community Disability Alliance Hunter (CDAH) and Diversity and Disability Alliance (DDAlliance): (1) peers with disability, (2) peer leaders with disability and (3) researchers with lived experience of disability and peer support. Data collection and creation methods include semistructured interviews, surveys and focus groups. Qualitative data will be analysed using thematic analysis through the lens of the researchers with lived experience.

Ethics and dissemination

Ethical approval was granted by the University of Newcastle Human Research Ethics Committee (Approval No: H-2021-0088). Dissemination includes peer-reviewed publications, presentations at local, national and international conferences and written reports for user-led organisations, disability service providers, disability agencies and people with disability.

Ischaemic stroke in patients with diabetes requiring urgent procedures during the COVID-19 pandemic in South Korea: a retrospective, nationwide, population-based cohort study using data from the National Emergency Department Information System

Objectives

The COVID-19 pandemic resulted in suboptimal care for ischaemic stroke. Patients with diabetes mellitus (DM), a high-risk group for stroke, had compromised routine care during the pandemic, which increases the chance of stroke. We examined influence of the COVID-19 pandemic on the management of ischaemic stroke in patients with DM in South Korea.

Design

Retrospective, nationwide, population-based cohort study.

Setting

Data from the National Emergency Department Information System.

Participants

We analysed 11 734 patients diagnosed with acute ischaemic stroke who underwent intravenous thrombolysis or endovascular thrombectomy between 2019 (the reference year) and 2020 (the pandemic year). Among them, 1014 subjects with DM were analysed separately.

Outcome measures

The frequency of emergency department (ED) visits, time from symptom onset to ED, from ED visit to admission and in-hospital mortality were compared between two periods in the overall population and in patients with DM.

Results

During the pandemic, the incidence of ischaemic stroke requiring urgent procedures increased by 7.57% in total and by 9.03% in patients with DM. Time delay from symptom onset to ED (reference vs pandemic, total: 1.50 vs 1.55 hours; p

Conclusions

During the COVID-19 pandemic, the incidence of ischaemic stroke requiring urgent procedures increased, and older patients with DM showed a higher ICU admission rate. However, the pandemic was not associated with an increased in-hospital stroke mortality.

Re‐imagining of an undergraduate, second‐degree entry, accelerated nursing program's curriculum utilizing a postmodern, learner‐centred lens and a concept‐based framework

Abstract

Introduction

It is necessary to re-imagine nursing curriculums utilizing a postmodern approach, as outdated teacher-centred methods of nursing education with emphasis on memorization versus critical thinking no longer meet the needs of the contemporary learner and the current challenges of the healthcare environment. There is an explicit need to redesign nursing curriculums that are future-oriented, adaptive and flexible and serve the learners' best interests.

Background

Distilled from a decade of teaching experience in an undergraduate, second-degree entry, accelerated nursing program, this paper describes the construction of a learner-centred, postmodern, concept-based nursing curriculum that aims to foster learners' inquiry skills, critical thinking, problem-solving, and experiential learning—all which develop learners' autonomy, self-direction, and lifelong learning. The objective is to foster learners' transformational and emancipatory learning and metacognition.

Discussion

An extensive review of the current trends, contemporary nursing knowledge for the past decade (2013–2023), and seminal literature on theories and frameworks paralleled with the review of current and future trends in Canadian and global health care, including the socio-economic, politico and environmental contexts, led to the formulation of a concept-based curriculum. Grounded in the constructivist paradigm, the curriculum applies interperetivist, critical, feminist, and indigenous lenses. The Strength-Based Nursing framework was selected as the core guiding framework. The curriculum's four curricular themes and foundational pillars were adopted directly from the framework to provide a starting point for concept development. These initial themes were then juxtaposed with relevant nursing, and social theories, policies, and frameworks, ensuring a robust coverage of modern nursing knowledge and allowing for the core concepts of the curriculum to emerge. A total of 21 concepts and 192 sub-concepts were developed.

Conclusion

Implications for future practice require nursing educators to receive support and professional development opportunities in developing skills and confidence in entering a classroom as co-learners and facilitators.

The enrichment process for family caregivers of persons living with dementia: A grounded theory approach

Abstract

Aim

Many persons living with dementia (PLWD) reside in the community and are cared for by family members. The aim of this qualitative study was to gain an understanding the enrichment process for family caregivers of PLWD in Taiwan.

Design

A grounded theory approach with face-to-face semi-structured interviews was conducted with family caregivers of PLWD in Taiwan.

Methods

Interview data from 30 family caregivers of PLWD recruited from dementia clinics or support groups in Taiwan were obtained from the first wave of a larger study conducted from January 2018 to September 2021. Glaser's grounded theory approach with theoretical sampling was used to understand the enrichment process of family caregivers of PLWD.

Results

Analysis indicated the core category that characterized the process of enrichment was ‘holding together’. Caregivers were able to maintain their connection to the person with dementia through activities that deepened their relationship and strengthened their bond. ‘Holding together’ included four components: maintaining continuity, creative interactions, interacting with humour and sharing pleasurable activities. Through these components, family caregivers generated positive interactions and relationships with the person living with dementia and sustained their motivation for caregiving. Three modifying elements facilitated or impeded the process of holding together: ‘previous daily interactions’, ‘caregiving beliefs’ and ‘filial piety’.

Conclusion

Through the enrichment process of ‘holding together’, family caregivers used different strategies to conduct pleasurable and meaningful activities with the person living with dementia to maintain and improve their relationship and enhance their happiness in life.

Impact

To facilitate the enrichment process, health care providers should encourage activities between family caregivers and PLWD that promote continuity, increase interactions, provide humour and foster pleasurable activities.

Reporting Method

This study adhered to the COREQ guideline checklist.

Quality of evidence supporting the role of hyperbaric oxygen therapy for diabetic foot ulcers

Abstract

The goal of this overview of systematic reviews (SRs) and meta-analyses (MAs) was to methodically gather, evaluate and summarize the data supporting the use of hyperbaric oxygen therapy (HBOT) to treat diabetic foot ulcers (DFUs). The Cochrane Library, Embase, PubMed, Web of Science and Embase were all searched thoroughly to identify SRs/MAs that qualified. AMSTAR-2 tool, PRISMA checklists and GRADE system were applied by two reviewers independently to assess the methodological quality, reporting and evidence quality of the included SRs/MAs, respectively. Eleven SRs/MAs were enrolled in this overview. According to AMSTAR-2, a very low methodological quality assessment was given to the included SRs/MAs due to the limitations of items 2, 4 and 7. For the PRISMA, the overall quality of reporting is not satisfactory due to missing reporting on protocol, search, as well as additional analysis. The majority of outcomes had low- to moderate-quality evidence, and no high-quality evidence was found to support the role of HBOT for DFUs, according to GRADE. To conclude, the potential of HBOT in treating DFUs is supported by evidence of low to moderate quality. More rigorously designed, high-level studies are needed in the future to determine the evidence for HBOT for DFU, including the timing, frequency and duration of HBOT interventions.

Promoting wound recovery through stable intestinal flora: Reducing post‐operative complications in colorectal cancer surgery patients

Abstract

In recent years, the relationship between intestinal flora and post-operative recovery, particularly in colorectal cancer (CRC) surgery patients, it has been hypothesized that intestinal flora stability influences wound healing, reduces complications and improves overall recovery outcomes after surgical interventions. This study examined the relationship between intestinal flora stability and post-operative recovery in patients undergoing CRC surgery. Between May 2020 and 2023, 80 CRC patients from our hospital's Colorectal Surgery Department were enrolled. A random number table was used to divide them into two categories. Both groups were subjected to distinct gastrointestinal preparation protocols. Indicators of clinical therapeutic effect, intestinal flora balance following surgery, post-operative complications and quality of life were evaluated. The observation group, which adhered to a distinct gastrointestinal regimen, demonstrated a statistically significant improvement in post-operative outcomes, with a clinical effectiveness rate of 97.5% compared to the control group's 75%. In addition, the observation group had a lower incidence of intestinal flora imbalance following surgery than the control group. The observation group had lower incidences of intestinal obstruction, infection, anastomotic leakage, incisional tumour implantation and delayed diarrhoea. Using the KPS score and the BMI, post-treatment assessments of the observation group's quality of life revealed significant enhancements in comparison to the control group. Additionally, wound healing rates were superior in the observation group, with a correlation between stable intestinal flora and decreased wound infection rates. The type of post-operative diet influenced the stabilization of the gut flora, with a high-fibre diet producing superior results in both groups. The stability of intestinal flora influences the post-operative rehabilitation of patients undergoing CRC surgery favourably. Appropriate bowel preparation and dietary considerations can reduce post-operative complications, improve wound healing rates and enhance overall quality of life.

Comparison of anaesthesia‐related outcomes in patients monitored by newly recruited nurse anaesthetists and anaesthesiologists: An observational study

Abstract

Aims

To compare anaesthesia-related outcomes between patients monitored by newly recruited nurse anaesthetists and those monitored by newly recruited anaesthesiologists.

Design

This was a retrospective study.

Methods

We conducted a retrospective study that collected demographic information on newly recruited nurse anaesthetists and anaesthesiologists between 2017 and 2022 and recorded information on patients within 6 months of monitoring. Postoperative pain, emergency agitation, nausea, and vomiting were designated anaesthesia-related outcomes. Propensity score matching was used to adjust for covariates. The study adhered to the STROBE guidelines.

Results

The study's statistical analysis included 4483 patients monitored by 22 newly recruited nurse anaesthetists and 4959 patients monitored by 23 newly recruited anaesthesiologists. Compared with patients monitored by newly trained anaesthesiologists, the patients monitored by nurse anaesthetists were younger (42.07 ± 20.00 vs. 47.39 ± 18.45 years, p < 0.001) and had a lower body mass index (23.56 ± 4.46 vs. 24.19 ± 4.25, p < 0.001). Patients monitored by anaesthesiologists had a greater proportion of women (61.62% vs. 59.25%, p < 0.001), a high proportion of ASA III and ASA IV (17.1% vs. 8.88%, p < 0.001), and a longer mean surgery duration (78.65 ± 59.01 vs. 70.70 ± 60.65 min, p < 0.001). After propensity score matching was used to adjust for covariates, no statistically significant differences were found in the prevalence of postoperative pain, emergency agitation, or postoperative nausea and vomiting between the two groups (p < 0.05).

Conclusion

Nurse anaesthetists monitoring alone during anaesthesia maintenance is feasible and safe. The two groups had no significant differences in the incidence of postoperative pain, emergency agitation, or postoperative nausea and vomiting.

Relevance to Clinical Practice

The shortage of anaesthesiologists leads to heavy work burden and high incidence of occupational burnout among anaesthesiologists. The study found that it was safe for nurse anaesthetists to perform anaesthetic monitoring alone in the operating room under the supervision of the attending anaesthesiologist and did reduce the burden of anaesthesiologists’ work. The results of the current study contribute to the expansion of occupational categories for nurse anaesthetists in countries where anaesthesiologists are in short supply. It provides new ideas for hospital administrators and policy-makers to formulate medical and nursing service policies.

Two distinct mechanisms lead to either oocyte or spermatocyte decrease in <i>C</i>. <i>elegans</i> after whole developmental exposure to γ-rays

Wildlife is subject to various sources of pollution, including ionizing radiation. Adverse effects can impact the survival, growth, or reproduction of organisms, later affecting population dynamics. In invertebrates, reproduction, which directly impacts population dynamics, has been found to be the most radiosensitive endpoint. Understanding the underlying molecular pathways inducing this reproduction decrease can help to comprehend species-specific differences in radiosensitivity. From our previous studies, we found that decrease in reproduction is life stage dependent in the roundworm Caenorhabditis elegans, possibly resulting from an accumulation of damages during germ cell development and gamete differentiation. To go further, we used the same experimental design to assess more precisely the molecular determinants of reproductive toxicity, primarily decreases in gamete number. As before, worms were chronically exposed to 50 mGy·h−1 external gamma ionizing radiation throughout different developmental periods (namely embryogenesis, gametogenesis, and full development). To enable cross species extrapolation, conserved molecular pathways across invertebrates and vertebrates were analysed: apoptosis and MAP kinase Ras/ERK (MPK-1), both involved in reproduction and stress responses. Our results showed that these pathways are life-stage dependent, resulting from an accumulation of damages upon chronic exposure to IR throughout the life development. The Ras/ERK pathway was activated in our conditions in the pachytene region of the gonad where it regulates cell fate including apoptosis, but not in the ovulation zone, where it controls oocyte maturation and ovulation. Additionally, assessment of germ cell proliferation via Ras/ERK pathway showed no effect. Finally, a functional analysis of apoptosis revealed that while the decrease of the ovulation rate is caused by DNA-damaged induced apoptosis, this process does not occur in spermatocytes. Thus, sperm decrease seems to be mediated via another mechanism, probably a decrease in germ cell proliferation speed that needs further investigation to better characterize sex-specific responses to IR exposure. These results are of main importance to describe radio-induced reprotoxic effects and contribute as weight of evidence for the AOP #396 “Deposition of ionizing energy leads to population decline via impaired meiosis”.
