Distribution and characteristics of bacteria on the hand during oropharyngeal swab collection: Which handwashing points are affected?

Abstract

Aims

To identify the contaminated areas of the hand collection and analyse the distribution characteristics of bacteria in the hand after swab collection.

Design

This study used a cross-sectional design.

Methods

A cross-sectional study sampling 50 pairs of hands (sampling hand and auxiliary hand) of healthcare workers was performed. Ten samples were collected from each participant. The optimal hand hygiene rates and bacterial colony counts of the whole hand and different hand sections without hand hygiene were identified as the primary outcomes.

Results

The optimal hand hygiene rates of the sampling hand and auxiliary hand were 88.8% (222/250) and 91.6% (229/250), respectively. The lowest optimal hand hygiene rates for the sampling hand and the auxiliary hand were both on the dorsal side of the finger and the dorsum of the hand (86.0%, 86.0% vs. 90.0%, 86.0%); the optimal hand hygiene rates for both sites of the sampling hand were 86.0% (43/50), and the optimal hand hygiene rates for the auxiliary hand were 90.0% (45/50) and 86.0% (43/50). The bacteria colony counts did not differ between the sampling hands and auxiliary hand.

Conclusions

The dorsal side of the finger and dorsum of the hand were the most likely to be contaminated during oropharyngeal swab collection. Therefore, it is essential to pay extra attention to hand hygiene care of these two sites during the collection process to minimize the risk of cross-contamination.

Reporting Method

The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were adopted in this study.

Developing and testing a reflection method for implementation of the informal care guideline in community nursing: Design‐based research

Abstract

Aim

To develop a reflection method for community nurses and certified nursing assistants to support the implementation of the Dutch Informal Care guideline in daily care.

Design

Design-based research.

Methods

A design group and four test groups of community nurses and nursing assistants were formed to develop a reflection method that aligns with the needs and preferences of its end-users. The design and test group meetings were video recorded. The video data were iteratively discussed and analysed thematically to adapt and refine the method and to identify its key features.

Results

A final reflection method was developed. Five main themes were identified from the analysis: the group, reflective triggers, knowledge about the guidelines, the coach and preconditions. The themes are linked to nine key features representing the building blocks of the reflection method. The key features are group size, participants with different (educational) backgrounds, pairs of participants, expressing thoughts, video feedback, reflection game, making the connection with the guideline, coaching as a process facilitator and meeting organizational and contextual conditions for implementation.

Conclusion

An evidence- and practice-based reflection method for community nurses and certified nursing assistants is developed to support the implementation. By involving community nurses and certified nursing assistants, the method closely matches their needs and preferences. Critical elements of the reflection method are a game element, video feedback and working in pairs in a group of participants from different (educational) backgrounds. Guidance is needed to make the transfer from theory to practice.

Impact

A reflection method for community nurses and certified nursing assistants was developed to enhance care work according to guideline recommendations, aiming to improve the care provided by informal caregivers.

Report Method

The COREQ guideline was used.

Patient or Public Contribution

This reflection method was developed in close collaboration with all stakeholders during the entire study.

Exploring the relationship between AM‐PAC scores and mobility components in falls and pressure injury risk assessment tools: A pathway to improve nursing clinical efficiency

Abstract

Background

Nurses routinely perform multiple risk assessments related to patient mobility in the hospital. Use of a single mobility assessment for multiple risk assessment tools could improve clinical documentation efficiency, accuracy and lay the groundwork for automated risk evaluation tools.

Purpose

We tested how accurately Activity Measure for Post-Acute Care (AM-PAC) mobility scores predicted the mobility components of various fall and pressure injury risk assessment tools.

Method

AM-PAC scores along with mobility and physical activity components on risk assessments (Braden Scale, Get Up and Go used within the Hendrich II Fall Risk Model®, Johns Hopkins Fall Risk Assessment Tool (JHFRAT) and Morse Fall Scale) were collected on a cohort of hospitalised patients. We predicted scores of risk assessments based on AM-PAC scores by fitting of ordinal logistic regressions between AM-PAC scores and risk assessments. STROBE checklist was used to report the present study.

Findings

AM-PAC scores predicted the observed mobility components of Braden, Get Up and Go and JHFRAT with high accuracy (≥85%), but with lower accuracy for the Morse Fall Scale (40%).

Discussion

These findings suggest that a single mobility assessment has the potential to be a good solution for the mobility components of several fall and pressure injury risk assessments.

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.

Trends in publication impact of evidence‐based healthcare terminology (2013–2022)

Abstract

Aims

This article explored the publication impact of evidence-based healthcare terminology to determine usage and discuss options for low usage terms.

Background

A plethora of terms describe the scholarship of evidence-based healthcare. Several terms are synonyms, creating redundancy and confusion. The abundance and overlap of terms may impede the discovery of evidence.

Design

This discursive article explored and discussed publication impact of evidence-based healthcare terms.

Methods

Evidence-based healthcare terms were identified, and their 10-year (2013–2022) publication impact was assessed in the CINAHL and Medline databases. A card sort method was also used to identify terms with low usage.

Results

A total of 18/32 terms were included in the review. The terms evidence-based practice, quality improvement, research and translational research were the most highly published terms. Publication data were presented yearly over a 10-year period. Most terms increased in publication use over time, except for three terms whose use decreased. Several terms related to translational research have multiple synonyms. It remains unknown whether these terms are interchangeable and possibly redundant, or if there are nuanced differences between terms.

Conclusion

We suggest a follow-up review in 3–5 years to identify publication trends to assess context and terms with continued low publication usage. Terms with persistent low usage should be considered for retirement in the reporting of scholarly activities. Additionally, terms with increasing publication trends should be treated as emerging terms that contribute to evidence-based healthcare terminology.

Implications for Nursing

Confusion about the use of appropriate terminology may hinder progress in the scholarship of evidence-based healthcare. We encourage scholars to be aware of publication impact as it relates to the use of specific terminology and be purposeful in the selection of terms used in scholarly projects and publications.

Background

Patient engagement is the active collaboration between patient partners and health system partners towards a goal of making decisions that centre patient needs—thus improving experiences of care, and overall effectiveness of health services in alignment with the Quintuple Aim. An important but challenging aspect of patient engagement is including diverse perspectives particularly those experiencing health inequities. When such populations are excluded from decision-making in health policy, practice and research, we risk creating a healthcare ecosystem that reinforces structural marginalisation and perpetuates health inequities.

Approach

Despite the growing body of literature on knowledge coproduction, few have addressed the role of power relations in patient engagement and offered actionable steps for engaging diverse patients in an inclusive way with a goal of improving health equity. To fill this knowledge gap, we draw on theoretical concepts of power, our own experience codesigning a novel model of patient engagement that is equity promoting, Equity Mobilizing Partnerships in Community, and extensive experience as patient partners engaged across the healthcare ecosystem. We introduce readers to a new conceptual tool, the Power Wheel, that can be used to analyse the interspersion of power in the places and spaces of patient engagement.

Conclusion

As a tool for ongoing praxis (reflection +action), the Power Wheel can be used to report, reflect and resolve power asymmetries in patient-partnered projects, thereby increasing transparency and illuminating opportunities for equitable transformation and social inclusion so that health services can meet the needs and priorities of all people.

Contemporary national outcomes of hyperbaric oxygen therapy in necrotizing soft tissue infections

by William Toppen, Nam Yong Cho, Sohail Sareh, Anders Kjellberg, Anthony Medak, Peyman Benharash, Peter Lindholm

Background

The role of hyperbaric oxygen therapy (HBOT) in necrotizing soft tissue infections (NSTI) is mainly based on small retrospective studies. A previous study using the 1998–2009 National Inpatient Sample (NIS) found HBOT to be associated with decreased mortality in NSTI. Given the argument of advancements in critical care, we aimed to investigate the continued role of HBOT in NSTI.

Methods

The 2012–2020 National Inpatient Sample (NIS) was queried for NSTI admissions who received surgery. 60,481 patients between 2012–2020 were included, 600 ( Results

Age, gender, and comorbidities were similar between the two groups. On bivariate comparison, the HBOT group had lower mortality rate ( Conclusions

After correction for differences, HBOT was associated with decreased mortality, amputations, and non-home discharges in NSTI with the tradeoff of increase to costs and length of stay.

Identification of the single and combined acute toxicity of Cr and Ni with <i>Heterocypris</i> sp. and the quantitative structure-activity relationship (QSAR) model

by Chi Su, Yilong Hua, Yi Liu, Shu Tao, Fei Jia, Wenhui Zhao, Wangyang Lin

Mining wastewater with heavy metals poses a serious threat to the ecological environment. However, the acute single and combined ecological effects of heavy metals, such as chromium (Cr) and nickel (Ni), on freshwater ostracods, and the development of relevant prediction models, remain poorly understood. In this study, Heterocypris sp. was chosen to investigate the single and combined acute toxicity of Cr and Ni. Then, the quantitative structure-activity relationship (QSAR) model was used to predict the combined toxicity of Cr and Ni. The single acute toxicity experiments revealed high toxicity for both Cr and Ni. In addition, Cr exhibited greater toxicity compared to Ni, as evidenced by its lower 96-hour half-lethal concentration (LC50) of 1.07 mg/L compared to 4.7 mg/L for Ni. Furthermore, the combined acute toxicity experiments showed that the toxicity of Cr-Ni was higher than Ni but lower than Cr. Compared with the concentration addition (CA) and independent action (IA) models, the predicted results of the QSAR model were more consistent with the experimental results for the Cr-Ni combined acute toxicity. So, the high accuracy of QSAR model identified its feasibility to predict the toxicity of heavy metal pollutants in mining wastewater.

Experiences of the clinical academic pathway: a qualitative study in Greater Manchester to improve the opportunities of minoritised clinical academics

Por: Lin · C.-Y. · Greco · C. · Radhakrishnan · H. · Finn · G. M. · Cowen · R. L. · Gardiner · N. J.
Objectives

The aim of this study was to explore the barriers and facilitators faced by clinical academics (CAs) in the Greater Manchester region, with particular attention to the experiences of minoritised groups.

Design

A qualitative study using semistructured interviews and focus groups was conducted. A reflexive thematic analysis was applied to identify key themes.

Setting

University of Manchester and National Health Service Trusts in the Greater Manchester region.

Participants

The sample of this study was composed of 43 participants, including CAs, senior stakeholders, clinicians and medical and dental students.

Results

Six themes were identified. CAs face several barriers and facilitators, some of which—(1) funding insecurity and (2) high workload between the clinic and academia—are common to all the CAs. Other barriers, including (3) discrimination that translates into struggles with self-worth and feeling of not belonging, (4) being or being perceived as foreign and (5) unequal distribution of care duties, particularly affect people from minoritised groups. In contrast, (6) mentorship was commonly identified as one of the most important facilitators.

Conclusions

Cultural and structural interventions are needed, such as introducing financial support for early career CAs and intercalating healthcare students to promote wider social and cultural change and increase the feelings of belonging and representation across the entire CA pipeline.

Evidence-informed and consensus-based statements about SAFEty of Physical Agent Modalities Practice in physiotherapy and rehabilitation medicine (SAFE PAMP): a national Delphi of healthcare scientific societies

Por: Gianola · S. · Bargeri · S. · Pellicciari · L. · Gambazza · S. · Rossettini · G. · Fulvio · A. · Genovese · V. · Benedini · M. · Proverbio · E. · Cecchetto · S. · Castellini · G. · Turolla · A. · SAFE PAMP Collaborators · Torresetti · Masturzo · Berliri · Roselli · Vercelli · Scorcu
Objective

A shared consensus on the safety about physical agent modalities (PAMs) practice in physiotherapy and rehabilitation is lacking. We aimed to develop evidence-informed and consensus-based statements about the safety of PAMs.

Study design and setting

A RAND-modified Delphi Rounds’ survey was used to reach a consensus. We established a steering committee of the Italian Association of Physiotherapy (Associazione Italiana di Fisioterapia) to identify areas and questions for developing statements about the safety of the most commonly used PAMs in physiotherapy and rehabilitation. We invited 28 National Scientific and Technical Societies, including forensics and lay members, as a multidisciplinary and multiprofessional panel of experts to evaluate the nine proposed statements and formulate additional inputs. The level of agreement was measured using a 9-point Likert scale, with consensus in the Delphi Rounds assessed using the rating proportion with a threshold of 75%.

Results

Overall, 17 (61%) out of 28 scientific and technical societies participated, involving their most representative members. The panel of experts mainly consisted of clinicians (88%) with expertise in musculoskeletal (47%), pelvic floor (24%), neurological (18%) and lymphatic (6%) disorders with a median experience of 30 years (IQR=17–36). Two Delphi rounds were necessary to reach a consensus. The final approved criteria list comprised nine statements about the safety of nine PAMs (ie, electrical stimulation neuromodulation, extracorporeal shock wave therapy, laser therapy, electromagnetic therapy, diathermy, hot thermal agents, cryotherapy and therapeutic ultrasound) in adult patients with a general note about populations subgroups.

Conclusions

The resulting consensus-based statements inform patients, healthcare professionals and policy-makers regarding the safe application of PAMs in physiotherapy and rehabilitation practice. Future research is needed to extend this consensus on paediatric and frail populations, such as immunocompromised patients.

Home-based Intervention with Semaglutide Treatment of Neuroleptic-Related Prediabetes (HISTORI): protocol describing a prospective, randomised, placebo controlled and double-blinded multicentre trial

Por: Ganeshalingam · A. A. · Uhrenholt · N. G. · Arnfred · S. · Gaede · P. H. · Bilenberg · N. · Frystyk · J.
Introduction

Subjects with schizophrenia have a 2–3 fold higher mortality rate than the general population and a reduced life expectancy of 10–20 years. Approximately one-third of this excess mortality has been attributed to obesity-related type 2 diabetes (T2D) and to cardiovascular disease. Glucagon-like peptide-1 (GLP-1) analogues increase satiety and delay gastric emptying, thereby reducing food intake and weight. GLP-1 analogues also exert beneficial effects on cardiovascular outcomes in high-risk patients with T2D.

Our aim is to investigate whether 30 weeks add-on treatment with the GLP-1 analogue semaglutide can reduce HbA1c sufficiently to reverse pre-diabetes and the metabolic syndrome in overweight schizophrenic patients.

Methods and analysis

We will perform a 30 week, two-armed, multicentre, superiority, double-blinded, randomised trial investigating the effect of weekly injections of semaglutide versus placebo in mental health facilities in Region of Southern Denmark and Region of Zealand, Denmark. In total, 154 adults with schizophrenia spectrum disease, aged 18–60 years treated with second generation antipsychotic treatment, HbA1c 39–47 mmol/mol and body mass index >27 kg/m2 will be randomised to injections of 1.0 mg semaglutide or placebo. The primary outcome is changes in HbA1c. Secondary outcomes encompass metabolic measures, psychotic symptoms and quality of life. Exploratory outcomes encompass insulin sensitivity, cardiovascular risk profile, medication adherence, general well-being and physical activity.

Ethics and dissemination

This study will be carried out in accordance with the Declaration of Helsinki and Good Clinical Practice guidelines. This research has obtained approval from both the Danish Medicines Agency and The Regional Committees on Health Research Ethics for Southern Denmark.

Evaluating the impact of movement tracking feedback on engagement with home exercise programmes of children with cerebral palsy using a new therapy app: a protocol for a mixed-methods single-case experimental design with alternating treatments

Por: Petrevska · M. · Wright · F. V. · Khan · A. · Munce · S. · Fehlings · D. · Biddiss · E.
Introduction

Children with cerebral palsy (CP) are prescribed home exercise programmes (HEPs) to increase the frequency of movement practice, yet adherence to HEPs can be low. This paper outlines the protocol for a single-case experimental design (SCED) with alternating treatments, using a new home therapy exercise application, Bootle Boot Camp (BBCamp), offered with and without movement tracking feedback. This study will explore the impact of feedback on engagement, movement quality, lower limb function and family experiences to help understand how technology-supported HEPs should be translated and the added value, if any, of movement tracking technology.

Methods and analysis

In this explanatory sequential mixed-methods study using a SCED, 16 children with CP (aged 6–12 years, Gross Motor Function Classification System levels I–II) will set lower limb goals and be prescribed an individualised HEP by their physiotherapist to complete using BBCamp on their home television equipped with a three-dimensional camera-computer system. Children will complete four weekly exercise sessions over 6 weeks. Children will be randomised to 1 of 16 alternating treatment schedules where BBCamp will provide or withhold feedback during the first 4 weeks. The version of BBCamp that results in the most therapeutic benefit will be continued for 2 final weeks. Goals will be re-evaluated and families interviewed. The primary outcome is adherence (proportion of prescribed exercise repetitions attempted) as a measure of behavioural engagement. Secondary outcomes are affective and cognitive engagement (smiley face ratings), exercise fidelity, lower limb function, goal achievement and participant experiences. SCED data will be analysed using visual and statistical methods. Quantitative and qualitative data will be integrated using joint displays.

Ethics and dissemination

Ethical approval was obtained from the Research Ethics Boards at Bloorview Research Institute and the University of Toronto. Results will be distributed through peer-reviewed journals and scientific conferences.

Do smoking abstinence periods among pregnant smokers improve birth weight? A secondary analysis of a randomised, controlled trial

Por: Berlin · I. · Goldzahl · L. · Jusot · F. · Berlin · N.
Objectives

Maternal smoking during pregnancy is associated with low birth weight (LBW). Reduction of cigarette consumption does not seem to improve birth weight but it is not known whether implementation of periods of smoking abstinence improves it. We assessed whether the number of 7-day periods of smoking abstinence during pregnancy may help reduce the number of newborns with LBW.

Design and setting

Secondary analysis of a randomised, controlled, multicentre, smoking cessation trial among pregnant smokers.

Participants

Pregnant women were included at

Primary outcome measure

Newborns with low birth weight.

Results

40 and 367 newborns were born with and without LBW, respectively. Adjusted for all available confounders, 3 or more periods of at least 7 days’ smoking abstinence during pregnancy was associated with reduced likelihood of LBW compared with no abstinence periods (OR = 0.124, 95% CI 0.03 to 0.53, p = 0.005). Reduction of smoking intensity by at least 50% was not associated with birth weight.

Conclusion

Aiming for several periods of smoking abstinence among pregnant smokers unable to remain continuously abstinent from smoking may be a better strategy to improve birth weight than reducing cigarette consumption.

Effectiveness of a community-based multicomponent lifestyle intervention (the ADA programme) to improve the quality of life of French breast cancer survivors: protocol for a pragmatic cluster randomised trial and embedded qualitative study

Por: El-Khoury · F. · Mino · J.-C. · Deschamps · N. · Lopez · C. · Menvielle · G. · Dargent-Molina · P.
Introduction

Breast cancer survivors (BCSs) are often faced with multiple mental and physical sequelae and are at increased risk of emotional distress, degraded health-related quality of life (HRQoL), chronic pain and fatigue.

Physical activity is strongly associated with improved HRQoL and survival rates; however, adherence rates to recommendations for a healthy lifestyle are seldom satisfactory among BCSs. Also, few studies have examined the effectiveness of multicomponent and personalised interventions that integrate physical activity and motivational techniques to improve the HRQoL of BCS.

Method and analysis

"Activité physique adaptée Doublée d’un Accompagnement d’après cancer" (ADA) is an integrated programme of physical activity enriched with a dietary and supportive care approach targeting BCS in the early post-treatment phase. The effectiveness of the ADA intervention will be evaluated using a cluster randomised controlled trial design with two arms (ADA programme vs usual care; 1:1 ratio).

The ADA intervention aims to recruit 160 participants and will be implemented by Siel Bleu, a non-profit association specialised in health prevention via adapted physical activity. Measurements will be performed at baseline, 3, 6 and 12 months after the start of the intervention. The primary outcome will be participants’ HRQoL, at 12 months measured by the Functional Assessment of Chronic Illness Therapy-Fatigue global score. Secondary outcome will include participants’ physical, social, emotional and functional well-being. The effect of the intervention on physical activity level, motivation for physical activity, relation to food and self-efficacy will also be evaluated.

Ethics and dissemination

The study was approved by the ‘CPP Paris XI’ Institutional Review Board on 5 May 2022 (Ref no.: 21.04512.000048-22004). The study’s findings will be shared through various channels, including academic publications, simplified reports for wider audiences and active engagement with medical and institutional organisations as well as patients’ associations.

HFE genotypes, haemochromatosis diagnosis and clinical outcomes at age 80 years: a prospective cohort study in the UK Biobank

Por: Lucas · M. R. · Atkins · J. L. · Pilling · L. C. · Shearman · J. D. · Melzer · D.
Objectives

HFE haemochromatosis genetic variants have an uncertain clinical penetrance, especially to older ages and in undiagnosed groups. We estimated p.C282Y and p.H63D variant cumulative incidence of multiple clinical outcomes in a large community cohort.

Design

Prospective cohort study.

Setting

22 assessment centres across England, Scotland, and Wales in the UK Biobank (2006–2010).

Participants

451 270 participants genetically similar to the 1000 Genomes European reference population, with a mean of 13.3-year follow-up through hospital inpatient, cancer registries and death certificate data.

Main outcome measures

Cox proportional HRs of incident clinical outcomes and mortality in those with HFE p.C282Y/p.H63D mutations compared with those with no variants, stratified by sex and adjusted for age, assessment centre and genetic stratification. Cumulative incidences were estimated from age 40 years to 80 years.

Results

12.1% of p.C282Y+/+ males had baseline (mean age 57 years) haemochromatosis diagnoses, with a cumulative incidence of 56.4% at age 80 years. 33.1% died vs 25.4% without HFE variants (HR 1.29, 95% CI: 1.12 to 1.48, p=4.7x10-4); 27.9% vs 17.1% had joint replacements, 20.3% vs 8.3% had liver disease, and there were excess delirium, dementia, and Parkinson’s disease but not depression. Associations, including excess mortality, were similar in the group undiagnosed with haemochromatosis. 3.4% of women with p.C282Y+/+ had baseline haemochromatosis diagnoses, with a cumulative incidence of 40.5% at age 80 years. There were excess incident liver disease (8.9% vs 6.8%; HR 1.62, 95% CI: 1.27 to 2.05, p=7.8x10-5), joint replacements and delirium, with similar results in the undiagnosed. p.C282Y/p.H63D and p.H63D+/+ men or women had no statistically significant excess fatigue or depression at baseline and no excess incident outcomes.

Conclusions

Male and female p.C282Y homozygotes experienced greater excess morbidity than previously documented, including those undiagnosed with haemochromatosis in the community. As haemochromatosis diagnosis rates were low at baseline despite treatment being considered effective, trials of screening to identify people with p.C282Y homozygosity early appear justified.

Tuberculosis infection and hypertension: prevalence estimates from the US National Health and Nutrition Examination Survey

Por: Salindri · A. D. · Auld · S. C. · Gujral · U. P. · Urbina · E. M. · Andrews · J. R. · Huaman · M. A. · Magee · M. J.
Objectives

Tuberculosis infection (TBI) is marked by dynamic host–pathogen interactions with persistent low-grade inflammation and is associated with increased risk of cardiovascular diseases (CVD) including acute coronary syndrome, myocardial infarction and stroke. However, few studies assess the relationship between TBI and hypertension, an intermediate of CVD. We sought to determine the association between TBI and hypertension using data representative of the adult US population.

Methods

We performed cross-sectional analyses using data from the 2011–2012 US National Health and Nutrition Examination Survey (NHANES). Eligible participants included adults with valid QuantiFERON-TB Gold In-Tube (QFT-GIT) test results who also had blood pressure measures and no history of TB disease. TBI was defined by a positive QFT-GIT. We defined hypertension by either elevated measured blood pressure levels (ie, systolic ≥130 mm Hg or diastolic ≥80 mm Hg) or known hypertension indications (ie, self-reported previous diagnosis or use of antihypertensive medications). Analyses were performed using robust quasi-Poisson regressions and accounted for the stratified probability sampling design of NHANES.

Results

The overall prevalence of TBI was 5.7% (95% CI 4.7% to 6.7%) and hypertension was present among 48.9% (95% CI 45.2% to 52.7%) of participants. The prevalence of hypertension was higher among those with TBI (58.5%, 95% CI 52.4% to 64.5%) than those without TBI (48.3%, 95% CI 44.5% to 52.1%) (prevalence ratio (PR) 1.2, 95% CI 1.1 to 1.3). However, after adjusting for confounders, the prevalence of hypertension was similar for those with and without TBI (adjusted PR 1.0, 95% CI 1.0 to 1.1). The unadjusted prevalence of hypertension was higher among those with TBI versus no TBI, especially among individuals without CVD risk factors including those with normal body mass index (PR 1.6, 95% CI 1.2 to 2.0), euglycaemia (PR 1.3, 95% CI 1.1 to 1.5) or non-smokers (PR 1.2, 95% CI 1.1 to 1.4).

Conclusions

More than half of adults with TBI in the USA had hypertension. Importantly, we observed a relationship between TBI and hypertension among those without established CVD risk factors.

Summary

The prevalence of hypertension was high (59%) among adults with TBI in the USA. In addition, we found that the prevalence of hypertension was significantly higher among adults with positive QFT without established hypertension risk factors.

Effects of COVID-19 contagion in cohabitants and family members on mental health and academic self-efficacy among university students in Sweden: a prospective longitudinal study

Por: Andersson · C. · Berman · A. H. · Lindfors · P. · Bendtsen · M.
Objective

This study used causal inference to estimate the longitudinal effects of contagion in cohabitants and family members on university students’ mental health and academic self-efficacy during the COVID-19 pandemic.

Design

A prospective longitudinal study including a baseline online measurement in May 2020, and online follow-ups after 5 months and 10 months. Participants were recruited through open-access online advertising.

Setting

Public universities and university colleges in Sweden.

Participants

The analytical sample included 2796 students.

Outcome measures

Contagion in cohabitants and in family members was assessed at baseline and at the 5-month follow-up. Mental health and academic self-efficacy were assessed at the 5-month and 10-month follow-ups.

Results

Mild symptoms reported in cohabitants at baseline resulted in negative mental health effects at follow-up 5 months later, and mild baseline symptoms in family members resulted in negative effects on academic self-efficacy at follow-ups both 5 and 10 months later.

Conclusions

Notwithstanding the lack of precision in estimated effects, the findings emphasise the importance of social relationships and the challenges of providing students with sufficient support in times of crisis.

Changes in medical student attendance and its impact on student educational outcomes: a systematic review protocol

Por: Nagappan · P. G. · Brown · S. · McManus · A. · Sayers · S. · Absar · S. · Tan · S. R. X. · Kuhn · I. · Lau · E. · Tulinius · C.
Introduction

The COVID-19 pandemic has had a significant impact on medical education, with many institutions shifting to online learning to ensure the safety of students and staff. However, there has been a decline in in-person attendance at medical schools across the UK and worldwide following the relaxation of social distancing rules and the reinstation of in-person teaching. Importantly, this trend has been observed prior to the pandemic. While reflected within the literature, there is currently no systematic review describing these changes. We aim to find out how medical students’ attendance is changing as documented within the literature and its impact on their educational outcomes.

Methods and analysis

This systematic review will follow the guidelines of the Centre of Research and Dissemination, Meta-analyses of Observational Studies in Epidemiology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We will search the major databases of Medline via Ovid, Embase via Ovid, Scopus, Web of Science, British Education Index via EBSCOhost and ERIC via EBSCOhost.

Two reviewers will independently screen each paper and extract data, with a third reviewer for dispute resolution. All studies reporting on medical students from various universities, both graduate and undergraduate and describing changes in attendance and/or students‘ educational outcomes will be included. Risk of bias in individual studies will be assessed using the Newcastle-Ottawa Scale and confidence in cumulative evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative Research approach. A narrative synthesis of the findings from all included studies will be reported.
