Regulatory emotional self‐efficacy and self‐compassion mediate anxiety, depression, body image distress and subjective well‐being in women with polycystic ovary syndrome: A cross‐sectional study

Abstract

Aims

This study aims to investigate the mediating role of regulatory emotional self-efficacy and self-compassion in the relationship among anxiety, depression, body image distress and subjective well-being among women with polycystic ovary syndrome.

Design

A cross-sectional study.

Methods

The study recruited 510 women with polycystic ovary syndrome from a tertiary hospital affiliated with a university in Hunan Province, China. The study employed several tools to collect data, including the Generalized Anxiety Scale, the Patient Health Questionnaire-9, the Body Image States Scale, the Self-Compassion Scale, the Regulatory Emotional Self-Efficacy Scale and the Index of Well-being questionnaire. Data analysis was carried out using descriptive analysis, spearman correlation analysis, ordinary least squares regression and bootstrapping.

Results

The study's findings indicate that regulatory emotional self-efficacy and self-compassion both act as mediators in the connection between anxiety, depression, body image distress and subjective well-being among women with polycystic ovary syndrome.

Conclusion

The study emphasizes the significance of regulatory emotional self-efficacy and self-compassion in promoting well-being among women with polycystic ovary syndrome. It also implies that interventions targeted at enhancing these factors could potentially enhance the subjective well-being of women affected by PCOS.

Impact

Our study's primary contribution is to underscore the crucial mediating roles of regulatory emotional self-efficacy and self-compassion in the relationship among anxiety, depression, body image distress and subjective well-being. Our study indicates that clinical practitioners should prioritize improving the regulatory emotional self-efficacy and self-compassion of women with polycystic ovary syndrome, reducing their anxiety, depression and body image distress and improving their subjective well-being.

Reporting Method

This study was reported according to the Standards for Reporting Qualitative Research (SRQR).

Patient or Public Contribution

No patient or public contribution outside of participation in the actual study for purposes of data collection.

The mental workload of ICU nurses performing human‐machine tasks and associated factors: A cross‐sectional questionnaire survey

Abstract

Aims

To assess the level of mental workload (MWL) of intensive care unit (ICU) nurses in performing different human-machine tasks and examine the predictors of the MWL.

Design

A cross-sectional questionnaire study.

Methods

Between January and February 2021, data were collected from ICU nurses (n = 427) at nine tertiary hospitals selected from five (east, west, south, north, central) regions in China through an electronic questionnaire, including sociodemographic questions, the National Aeronautics and Space Administration Task Load Index, General Self-Efficacy Scale, Difficulty-assessing Index System of Nursing Operation Technique, and System Usability Scale. Descriptive statistics, t-tests, one-way ANOVA and multiple linear regression models were used.

Results

ICU nurses experienced a medium level of MWL (score 52.04 on a scale of 0–100) while performing human-machine tasks. ICU nurses' MWL was notably higher in conducting first aid and life support tasks (using defibrillators or ventilators). Predictors of MWL were task difficulty, system usability, professional title, age, self-efficacy, ICU category, and willingness to study emerging technology actively. Task difficulty and system usability were the strongest predictors of nearly all typical tasks.

Conclusion

ICU nurses experience a medium MWL while performing human-machine tasks, but higher mental, temporal, and effort are perceived compared to physical demands. The MWL varied significantly across different human-machine tasks, among which are significantly higher: first aid and life support and information-based human-machine tasks. Task difficulty and system availability are decisive predictors of MWL.

Impact

This is the first study to investigate the level of MWL of ICU nurses performing different representative human-machine tasks and to explore its predictors, which provides a reference for future research. These findings suggest that healthcare organizations should pay attention to the MWL of ICU nurses and develop customized management strategies based on task characteristics to maintain a moderate level of MWL, thus enabling ICU nurses to perform human-machine tasks better.

Paediatric off-label use of drugs in Gansu, China: a multicentre cross-sectional study

Por: Meng · M. · Ge · B. · Lei · W. · Wu · Y. · Tian · M. · Lu · Y. · Shao · T. · Yang · Y. · Luo · X. · Luo · J. · Gao · Y. · Li · Q. · Chen · Y.
Objective

To examine the current prevalence and cost of paediatric off-label drug prescriptions in Gansu, China, and the potential influencing factors.

Design

The prevalence of off-label prescriptions in paediatrics was evaluated according to the National Medical Products Administration drug instructions in the China Pharmaceutical Reference (China Pharmaceutical Reference, MCDEX) database. The evidence of the prescription was determined by existing clinical practice guidelines and the Thomson Grade in the Micromedex 2021 compendium. We used logistic regression to investigate the characteristics that influence paediatric off-label drug use after single-factor regression analysis.

Setting

A multicentre cross-sectional study of outpatient paediatric prescriptions in 196 secondary and tertiary hospitals in Gansu Province, China, in March and September 2020.

Results

We retrieved 104 029 paediatric prescriptions, of which 39 480 (38.0%) contained off-label use. The most common diseases treated by off-label drugs were respiratory system diseases (n=15 831, 40.1%). A quarter of off-label prescriptions had adequate evidence basis (n=10 130, 25.6%). Unapproved indications were the most common type of off-label drug use (n=25 891, 65.6%). A total of 1177 different drugs were prescribed off-label, with multienzyme tablets being the most common drug (n=1790, 3.5%). The total cost of the prescribed off-label drugs was ¥106 116/day. Off-label prescriptions were less frequent in tertiary than in secondary hospitals. Topical preparations were more commonly prescribed off-label than other types of drugs. Senior-level clinicians prescribed drugs off-label more often than intermediate and junior clinicians.

Conclusion

Off-label drug use is widespread in paediatric practice in China. Three-quarters of the prescriptions may potentially include inappropriate medication use, resulting in a daily economic burden of about ¥81 000 in 2020 in Gansu Province with 25 million inhabitants. The management of off-label drug use in paediatrics in China needs improvement.

Cost-effectiveness of a complex continuum of care intervention targeting women and children: protocol for an economic evaluation of the Bukhali trial in South Africa

Por: Palmer · T. · Leiva Granados · R. · Draper · C. · Norris · S. A. · Batura · N.
Introduction

As nearly two-thirds of women presenting at their first antenatal visit are either overweight or obese in urban South Africa, the preconception period is an opportunity to optimise health and offset transgenerational risk of both obesity and non-communicable diseases. This protocol describes the planned economic evaluation of an individually randomised controlled trial of a complex continuum of care intervention targeting women and children in Soweto, South Africa (Bukhali trial).

Methods and analysis

The economic evaluation of the Bukhali trial will be conducted as a within-trial analysis from both provider and societal perspectives. Incremental costs and health outcomes of the continuum of care intervention will be compared with standard care. The economic impact on implementing agencies (programme costs), healthcare providers, participants and their households will be estimated. Incremental cost-effectiveness ratios (ICERs) will be calculated in terms of cost per case of child adiposity at age years averted. Additionally, ICERs will also be reported in terms of cost per quality-adjusted life year gained. If Bukhali demonstrates effectiveness, we will employ a decision analytical model to examine the cost-effectiveness of the intervention over a child’s lifetime. A Markov model will be used to estimate long-term health benefits, healthcare costs and cost-effectiveness. Probabilistic sensitivity analyses will be conducted to explore uncertainty and ensure robust results. An analysis will be conducted to assess the equity impact of the intervention, by comparing intervention impact within quintiles of socioeconomic status.

Ethics and dissemination

The Bukhali trial economic evaluation has ethical approval from the Human Ethics Research Committee of the University of the Witwatersrand, Johannesburg, South Africa (M240162). The results of the economic evaluation will be disseminated in a peer-reviewed journal and presented at a relevant international conference.

Role of Gut Microbe Composition in Psychosocial Symptom Response to Exercise Training in Breast Cancer Survivors (ROME) study: protocol for a randomised controlled trial

Por: Little · R. B. · Carter · S. J. · Motl · R. W. · Hunter · G. · Cook · A. · Liu · N. · Krontiras · H. · Lefkowitz · E. J. · Turan · B. · Schleicher · E. · Rogers · L. Q.
Introduction

Breast cancer survivors have an increased risk for chronic fatigue and altered gut microbiota composition, both with negative health and quality of life affects. Exercise modestly improves fatigue and is linked to gut microbial diversity and production of beneficial metabolites. Studies suggest that gut microbiota composition is a potential mechanism underlying fatigue response to exercise. Randomised controlled trials testing the effects of exercise on the gut microbiome are limited and there is a scarcity of findings specific to breast cancer survivors. The objective of this study is to determine if fitness-related modifications to gut microbiota occur and, if so, mediate the effects of aerobic exercise on fatigue response.

Methods and analysis

The research is a randomised controlled trial among breast cancer survivors aged 18–74 with fatigue. The primary aim is to determine the effects of aerobic exercise training compared with an attention control on gut microbiota composition. The secondary study aims are to test if exercise training (1) affects the gut microbiota composition directly and/or indirectly through inflammation (serum cytokines), autonomic nervous system (heart rate variability) or hypothalamic-pituitary-adrenal axis mediators (hair cortisol assays), and (2) effects on fatigue are direct and/or indirect through changes in the gut microbiota composition. All participants receive a standardised controlled diet. Assessments occur at baseline, 5 weeks, 10 weeks and 15 weeks (5 weeks post intervention completion). Faecal samples collect the gut microbiome and 16S gene sequencing will identify the microbiome. Fatigue is measured by a 13-item multidimensional fatigue scale.

Ethics and dissemination

The University of Alabama at Birmingham Institutional Review Board (IRB) approved this study on 15 May 2019, UAB IRB#30000320. A Data and Safety Monitoring Board convenes annually or more often if indicated. Findings will be disseminated in peer-reviewed journals and conference presentations.

Trial registration number

ClinicalTrials.gov, NCT04088708.

First‐line managers' experience of guideline implementation during the COVID‐19 pandemic

Abstract

Aim(s)

To explore first-line managers' experience of guideline implementation in orthopaedic care during the COVID-19 pandemic.

Design

A descriptive, qualitative study.

Methods

Semi-structured interviews with 30 first-line nursing and rehabilitation managers in orthopaedic healthcare at university, regional and local hospitals. The interviews were analysed by thematic analysis.

Results

First-line managers described the implementation of guidelines related to the pandemic as different from everyday knowledge translation, with a swifter uptake and time freed from routine meetings in order to support staff in adoption and adherence. The urgent need to address the crisis facilitated guideline implementation, even though there were specific pandemic-related barriers such as staffing and communication issues. An overarching theme, Hanging on to guidelines for dear life, is substantiated by three themes: Adapting to facilitate change, Anchoring safety through guidelines and Embracing COVID guidelines.

Conclusion

A health crisis such as the COVID-19 pandemic can generate enabling elements for guideline implementation in healthcare, despite prevailing or new hindering components. The experience of guideline implementation during the COVID-19 pandemic can improve understanding of context aspects that can benefit organizations in everyday translation of evidence into practice.

Implications for the Profession and/or Patient Care

Recognizing what enabled guideline implementation in a health crisis can help first-line managers to identify local enabling context elements and processes. This can facilitate future guideline implementation.

Impact

During the COVID-19 pandemic, the healthcare context and staff's motivation for guideline recognition and adoption changed. Resources and ways to bridge barriers in guideline implementation emerged, although specific challenges arose. Nursing managers can draw on experiences from the COVID-19 pandemic to support implementation of new evidence-based practices in the future.

Reporting Method

This study adheres to the EQUATOR guidelines by using Standards for Reporting Qualitative Research (SRQR).

A scoping review of the role of policy in mitigating childhood obesity in underserved populations using the RE‐AIM framework

Abstract

Background

Childhood obesity is an escalating crisis in the United States. Health policy may impact this epidemic which disproportionally affects underserved populations.

Aim

The aim was to use the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) framework to assess health policy impact on preventing or treating school-aged children (5 > 18 years) with obesity in underserved populations.

Methods

A scoping review of 842 articles was conducted. Twenty-four articles met the inclusion criteria and underwent data extraction.

Results

Twelve studies included subgroup analysis, with four suggesting an impact of policy on at-risk groups. None of the 24 studies fully applied the RE-AIM framework. Policies positively impacted childhood obesity in 12 studies across the sample.

Linking Evidence to Action

Our review revealed inconsistent evidence for the effectiveness of policy on childhood obesity, perhaps due to the lack of focus on the social determinants of health. In addition, many studies did not evaluate the outcomes for underserved populations. Therefore, we propose more attention to social determinants in future legislation and evaluation of policy effectiveness on underserved populations. Findings identify an urgent need for the design, implementation, and evaluation of policies specifically directed to address the inequities of racism, social injustices, and social determinants of health that impact childhood obesity in the United States. Future work needs to identify who was reached by the policy, who benefitted from the policy, and how policies were implemented to address obesity-related health disparities. Nurses should advocate for the evaluation of childhood obesity policies, particularly in underserved populations, to determine effectiveness. Nurses, particularly those trained in population and community health and research, should advocate for policy research that considers inequities rather than controls for these variables. Multi-layered interventions can then be tailored to sub-populations and evaluated more effectively.

Effects of comprehensive nursing interventions on wound pain in patients undergoing catheter insertion for peritoneal dialysis

Abstract

This study investigates the effects of comprehensive nursing interventions on wound pain in patients undergoing catheter insertion for peritoneal dialysis. Sixty patients who underwent catheter insertion for peritoneal dialysis from January 2021 to January 2023 at our hospital were selected as subjects and randomly divided into an experimental group and a control group using a random number table method. The control group received routine nursing care, while the experimental group was subjected to comprehensive nursing interventions. The study compared the impact of nursing measures on visual analogue scale (VAS), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and nursing satisfaction between the two groups. The analysis revealed that on the third, fifth and seventh days post-intervention, the experimental group's wound VAS scores were significantly lower than those of the control group (p < 0.001). Furthermore, levels of anxiety and depression were markedly lower in the experimental group compared with the control group (p < 0.001). In addition, the nursing satisfaction rate was significantly higher in the experimental group than in the control group (96.67% vs. 73.33%, p = 0.011). This study indicates that the application of comprehensive nursing interventions in patients undergoing catheter insertion for peritoneal dialysis is highly effective. It can alleviate wound pain and negative emotions to a certain extent, while also achieving high patient satisfaction, thus demonstrating significant clinical value.

Por: Medeiros · P. · Koebel · J. · Yu · A. · Kazemi · M. · Nicholson · V. · Frank · P. · Persad · Y. · O'Brien · N. · Bertozzi · B. · Smith · S. · Ndung'u · M. · Fraleigh · A. · Gagnier · B. · Cardinal · C. · Webster · K. · Sanchez · M. · Lee · M. · Lacombe-Duncan · A. · Logie · C. H. · Gormley
Objectives

The community-based, longitudinal, Canadian HIV Women’s Sexual and Reproductive Health Cohort Study (CHIWOS) explored the experiences of women with HIV in Canada over the past decade. CHIWOS’ high-impact publications document significant gaps in the provision of healthcare to women with HIV. We used concept mapping to analyse and present a summary of CHIWOS findings on women’s experiences navigating these gaps.

Design

Concept mapping procedures were performed in two steps between June 2019 and March 2021. First, two reviewers (AY and PM) independently reviewed CHIWOS manuscripts and conference abstracts written before 1 August 2019 to identify main themes and generate individual concept maps. Next, the preliminary results were presented to national experts, including women with HIV, to consolidate findings into visuals summarising the experiences and care gaps of women with HIV in CHIWOS.

Setting

British Columbia, Ontario and Quebec, Canada.

Participants

A total of 18 individual CHIWOS team members participated in this study including six lead investigators of CHIWOS and 12 community researchers.

Results

Overall, a total of 60 peer-reviewed manuscripts and conference abstracts met the inclusion criteria. Using concept mapping, themes were generated and structured through online meetings. In total, six composite concept maps were co-developed: quality of life, HIV care, psychosocial and mental health, sexual health, reproductive health, and trans women’s health. Two summary diagrams were created encompassing the concept map themes, one for all women and one specific to trans women with HIV. Through our analysis, resilience, social support, positive healthy actions and women-centred HIV care were highlighted as strengths leading to well-being for women with HIV.

Conclusions

Concept mapping resulted in a composite summary of 60 peer-reviewed CHIWOS publications. This activity allows for priority setting to optimise care and well-being for women with HIV.

Adherence to PRISMA 2020 reporting guidelines and scope of systematic reviews published in nursing: A cross‐sectional analysis

Abstract

Introduction

Systematic reviews are considered the highest level of evidence that can help guide evidence-informed decisions in nursing practice, education, and even health policy. Systematic review publications have increased from a sporadic few in 1980s to more than 10,000 systematic reviews published every year and around 30,000 registered in prospective registries.

Methods

A cross-sectional design and a variety of data sources were triangulated to identify the journals from which systematic reviews would be evaluated for adherence to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 reporting guidelines and scope. Specifically, this study used the PRISMA 2020 reporting guidelines to assess the reporting of the introduction, methods, information sources and search strategy, study selection process, quality/bias assessments, and results and discussion aspects of the included systematic reviews.

Results

Upon review of the 215 systematic reviews published in 10 top-tier journals in the field of nursing in 2019 and 2020, this study identified several opportunities to improve the reporting of systematic reviews in the context of the 2020 PRISMA statement. Areas of priority for reporting include the following key areas: (1) information sources, (2) search strategies, (3) study selection process, (4) bias reporting, (5) explicit discussion of the implications to policy, and lastly, the need for (6) prospective protocol registration.

Discussion

The use of the PRISMA 2020 guidelines by authors, peer reviewers, and editors can help to ensure the transparent and detailed reporting of systematic reviews published in the nursing literature.

Clinical Relevance

Systematic reviews are considered strong research evidence that can guide evidence-based practice and even clinical decision-making. This paper addresses some common methodological and process issues among systematic reviews that can guide clinicians and practitioners to be more critical in appraising research evidence that can shape nursing practice.

The impact of long‐term antihypertensive treatment on wound healing after major non‐cardiac surgery in patients with cardiovascular diseases: A meta‐analysis

Abstract

Hypertension is a prevalent condition that poses significant challenges in the perioperative management of patients undergoing major non-cardiac surgery, particularly concerning wound healing and scar formation. This meta-analysis assesses the impact of long-term antihypertensive treatment on postoperative wound healing, examining data from seven studies involving patients who received such treatments compared to untreated controls. Our findings reveal that long-term antihypertensive therapy is associated with significantly improved wound healing outcomes, as indicated by lower REEDA scores (I 2 = 96%, SMD = −25.71, 95% CI: [−33.71, −17.70], p < 0.01) 1 week post-surgery and reduced scar formation, demonstrated by lower Manchester Scar Scale scores (I 2 = 93%, SMD = −37.29, 95% CI: [−44.93, −29.64], p < 0.01) 2 months post-surgery. These results underscore the potential benefits of antihypertensive treatment in enhancing surgical recovery and offer insights into optimising perioperative care for hypertensive patients.

The effect of primary closure versus secondary closure techniques on postoperative wound pain in patients undergoing mandibular surgery: A meta‐analysis

Por: Lina Zhang · Lei Li

Abstract

This research is intended to explore the influence of second and first degree closure methods on the degree of wound pain and swelling of the face following the removal of the mandible. For the purpose of this study, three data sets, including PubMed and Embase, were selected. A separate statistical analysis was conducted on the choice of the trial, the collection of data and the risk of bias. Differences between trials were analysed with a chi-square approach, with data analyses dependent on I 2. A sensitivity analysis was conducted, and a possible publication bias was evaluated. Ultimately, nine qualifying trials were chosen out of an original pool of 1922 related trials following an in-depth evaluation under the eligibility and exclusion criteria, as well as a follow-up screening. The results indicated that there was no statistically significant change in the degree of post-operation pain after 1 day operation between one or secondary closures of treatment (MD, −0.46; 95% CI, −0.93, 0.01, p = 0.06); the results showed that there were no statistically significant differences in post-operation wound pain after 3 days in two group (MD, −0.15; 95% CI, −0.68, 0.37, p = 0.56); the results showed that there were no statistically different effects on the post-operation wound pain after the 7th day in two groups (MD, −0.14; 95% CI, −0.31, 0.03, p = 0.1). The results showed that there were no statistically different effects on the post-operation wound pain after the 1 day in two groups (MD, −0.26; 95% CI, −0.38, −0.13, p < 0.0001); on the 3rd day after surgery, the face was significantly smaller swelling in the secondary closure of closure compared with the first-stage closure group (MD, −0.70; 95% CI, −1.40, −0.00, p = 0.05). While there is no obvious effect on post-operation wound pain in patients with mandibular surgery, there is significant difference in post-operation face swelling. The findings do not support a preference for any of these methods.

Integrating genomics into Canadian oncology nursing policy: Insights from a comparative policy analysis

Abstract

Aim

To learn from two jurisdictions with mature genomics-informed nursing policy infrastructure—the United States (US) and the United Kingdom (UK)—to inform policy development for genomics-informed oncology nursing practice and education in Canada.

Design

Comparative document and policy analysis drawing on the 3i + E framework.

Methods

We drew on the principles of a rapid review and identified academic literature, grey literature and nursing policy documents through a systematic search of two databases, a website search of national genomics nursing and oncology nursing organizations in the US and UK, and recommendations from subject matter experts on an international advisory committee. A total of 94 documents informed our analysis.

Results

We found several types of policy documents guiding genomics-informed nursing practice and education in the US and UK. These included position statements, policy advocacy briefs, competencies, scope and standards of practice and education and curriculum frameworks. Examples of drivers that influenced policy development included nurses' values in aligning with evidence and meeting public expectations, strong nurse leaders, policy networks and shifting healthcare and policy landscapes.

Conclusion

Our analysis of nursing policy infrastructure in the US and UK provides a framework to guide policy recommendations to accelerate the integration of genomics into Canadian oncology nursing practice and education.

Implications for the profession

Findings can assist Canadian oncology nurses in developing nursing policy infrastructure that supports full participation in safe and equitable genomics-informed oncology nursing practice and education within an interprofessional context.

Impact

This study informs Canadian policy development for genomics-informed oncology nursing education and practice. The experiences of other countries demonstrate that change is incremental, and investment from strong advocates and collaborators can accelerate the integration of genomics into nursing. Though this research focuses on oncology nursing, it may also inform other nursing practice contexts influenced by genomics.

Retinoid orphan receptor gamma t (rorγt) promotes inflammatory eosinophilia but is dispensable for innate immune-mediated colitis

by Alvaro Torres-Huerta, Katelyn Ruley-Haase, Theodore Reed, Antonia Boger-May, Derek Rubadeux, Lauren Mayer, Arpitha Mysore Rajashekara, Morgan Hiller, Madeleine Frech, Connor Roncagli, Cameron Pedersen, Mary Catherine Camacho, Lauren Hollmer, Lauren English, Grace Kane, David L. Boone

Inflammatory bowel diseases (IBD) result from uncontrolled inflammation in the intestinal mucosa leading to damage and loss of function. Both innate and adaptive immunity contribute to the inflammation of IBD and innate and adaptive immune cells reciprocally activate each other in a forward feedback loop. In order to better understand innate immune contributions to IBD, we developed a model of spontaneous 100% penetrant, early onset colitis that occurs in the absence of adaptive immunity by crossing villin-TNFAIP3 mice to RAG1-/- mice (TRAG mice). This model is driven by microbes and features increased levels of innate lymphoid cells in the intestinal mucosa. To investigate the role of type 3 innate lymphoid cells (ILC3) in the innate colitis of TRAG mice, we crossed them to retinoid orphan receptor gamma t deficient (Rorγt-/-) mice. Rorγt-/- x TRAG mice exhibited markedly reduced eosinophilia in the colonic mucosa, but colitis persisted in these mice. Colitis in Rorγt-/- x TRAG mice was characterized by increased infiltration of the intestinal mucosa by neutrophils, inflammatory monocytes, macrophages and other innate cells. RNA and cellular profiles of Rorγt-/- x TRAG mice were consistent with a lack of ILC3 and ILC3 derived cytokines, reduced antimicrobial factors, increased activation oof epithelial repair processes and reduced activation of epithelial cell STAT3. The colitis in Rorγt-/- x TRAG mice was ameliorated by antibiotic treatment indicating that microbes contribute to the ILC3-independent colitis of these mice. Together, these gene expression and cell signaling signatures reflect the double-edged sword of ILC3 in the intestine, inducing both proinflammatory and antimicrobial protective responses. Thus, Rorγt promotes eosinophilia but Rorγt and Rorγt-dependent ILC3 are dispensable for the innate colitis in TRAG mice.

Inhaled Nitric Oxide ReDuce postoperatIve pulmoNAry complicaTions in patiEnts with recent COVID-19 infection (INORDINATE): protocol for a randomised controlled trial

Por: Zheng · Z. · Wang · L. · Wang · S. · Fan · Q. · Zhang · H. · Luo · G. · Gao · B. · Yang · X. · Zhao · B. · Wang · X. · Dong · H. · Nie · H. · Lei · C.
Background

A history of SARS-CoV-2 infection has been reported to be associated with an increased risk of postoperative pulmonary complications (PPCs). Even mild PPCs can elevate the rates of early postoperative mortality, intensive care unit (ICU) admission and prolong the length of ICU and/or hospital stays. Consequently, it is crucial to develop perioperative management strategies that can mitigate these increased risks in surgical patients who have recently been infected with SARS-CoV-2. Accumulating evidence suggests that nitric oxide (NO) inhalation might be effective in treating COVID-19. NO functions in COVID-19 by promoting vasodilation, anticoagulation, anti-inflammatory and antiviral effects. Therefore, our study hypothesises that the perioperative use of NO can effectively reduce PPCs in patients with recent SARS-CoV-2 infection.

Method and analysis

A prospective, double-blind, single-centre, randomised controlled trial is proposed. The trial aims to include participants who are planning to undergo surgery with general anaesthesia and have been recently infected with SARS-CoV-2 (within 7 weeks). Stratified allocation of eligible patients will be performed at a 1:1 ratio based on the predicted risk of PPCs using the Assess Respiratory Risk in Surgical Patients in Catalonia risk index and the time interval between infection and surgery.

The primary outcome of the study will be the presence of PPCs within the first 7 days following surgery, including respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm and aspiration pneumonitis. The primary outcome will be reported as counts (percentage) and will be compared using a two-proportion 2 test. The common effect across all primary components will be estimated using a multiple generalised linear model.

Ethics and dissemination

The trial is approved by the Institutional Review Board of Xijing Hospital (KY20232058-F1). The findings, including positive, negative and inconclusive results, will be published in scientific journals with peer-review processes.

Trial registration number

NCT05721144.

Impact effects of COVID‐19 pandemic on chronic disease patients: A longitudinal prospective study

Abstract

Aims

To assess the effects of COVID-19 pandemic on clinical variables as part of the routine clinical monitoring of patients with chronic diseases in primary care.

Design

A prospective longitudinal study was conducted in primary care centres of the Andalusian Health Service.

Methods

Data were recorded before the pandemic (T1), during the declaration of the state of emergency (T2) and in the transition phase (T3). The Barthel index and the Short Portable Mental Status Questionnaire (SPMSQ) were used to analyse functional and cognitive changes at the three time points. HbA1c, systolic and diastolic blood pressure, heart rate, BMI and lipid levels were assessed as clinical variables. Descriptive statistics and non-parametric chi-square test were used for analysis. STROBE checklist was used for the preparation of this paper.

Results

A total fo148 patients with chronic conditions were included in the analysis. Data analysis revealed in T2 only significant reductions in BMI, total levels of cholesterol and HDL during the onset of the pandemic. Barthel Index, SPMSQ, blood pressure and triglycerides and LDL levels worsened in T2, and the negative effects were maintained in T3. Compared to pre-pandemic values, HbA1c levels improved in T3, but HDL levels worsened.

Conclusions

COVID-19 has drastically disrupted several functional, cognitive and biological variables. These results may be useful in identifying clinical parameters that deserve closer attention in the case of a new health crisis. Further studies are needed to assess the potential impacts of each specific chronic condition.

Impact

Cognitive and functional status, blood pressure and triglycerides and LDL levels worsen in short term, maintaining the negative effects in medium-term.
