Intranasal antihistamines and corticosteroids in the treatment of allergic rhinitis: a systematic review and meta-analysis protocol

Por: Sousa-Pinto · B. · Vieira · R. J. · Brozek · J. · Cardoso-Fernandes · A. · Lourenco-Silva · N. · Ferreira-da-Silva · R. · Ferreira · A. · Gil-Mata · S. · Bedbrook · A. · Klimek · L. · Fonseca · J. A. · Zuberbier · T. · Schünemann · H. J. · Bousquet · J.
Introduction

Intranasal antihistamines and corticosteroids are some of the most frequently used drug classes in the treatment of allergic rhinitis. However, there is uncertainty as to whether effectiveness differences may exist among different intranasal specific medications. This systematic review aims to analyse and synthesise all evidence from randomised controlled trials (RCTs) on the effectiveness of intranasal antihistamines and corticosteroids in rhinitis nasal and ocular symptoms and in rhinoconjunctivitis-related quality-of-life.

Methods and analysis

We will search four electronic bibliographic databases and three clinical trials databases for RCTs (1) assessing patients ≥12 years old with seasonal or perennial allergic rhinitis and (2) comparing the use of intranasal antihistamines or corticosteroids versus placebo. Assessed outcomes will include the Total Nasal Symptom Score (TNSS), the Total Ocular Symptom Score (TOSS) and the Rhinoconjunctivitis Quality-of-Life Questionnaire (RQLQ). We will assess the methodological quality of included primary studies by using the Cochrane risk-of-bias tool. Certainty in the body of evidence for the analysed outcomes will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. We will perform a random-effects meta-analysis for each assessed medication and outcome, presenting results as pooled mean differences and standardised mean differences. Heterogeneity will be explored by sensitivity and subgroup analyses, considering (1) the risk of bias, (2) the follow-up period and (3) the drug dose.

Ethics and dissemination

Ethical considerations will not be required. Results will be disseminated in a peer-review journal.

Latent profile analysis of nurses perceived professional benefits in China: a cross-sectional study

Por: Sun · C. · Jiang · H. · Yao · Q. · Wang · X. · Wen · X. · Liu · H.
Objective

To identify profiles of nurses’ perceived professional benefits as well as their predictors.

Design

Cross-sectional study.

Setting

The study was carried out online in China.

Methods

From 6 July to 27 July 2022, a total of 1309 registered nurses participated in the survey by convenient sampling. We collected the Nurses’ Perceived Professional Benefits Questionnaire and demographic data. Using latent profile analysis (LPA), subgroups of nurses’ perceived professional benefits were identified. Moreover, univariate and multinomial logistic regression analyses were conducted to find the factors that were linked with the profiles.

Results

The survey was validly completed by 1309 nurses, with a 92.9% effective return rate. The findings of the LPA demonstrated three unique profiles: low-perceived professional benefits (11.8%), moderate-perceived professional benefits (57.1%) and high-perceived professional benefits (31.1%). There was a correlation between marital status, the number of night shifts per month and leadership role.

Conclusions

According to our research, registered nurses have three unique professional benefit profiles. In order to sustain the nursing workforce, despite the fact that nurses get a high level of professional benefits, interventions are necessary to increase nurses’ perception of their professional value.

Interventions to reduce interpersonal stigma towards patients with a mental dysregulation for ambulance and emergency department healthcare professionals: review protocol for an integrative review

Por: Van de Glind · G. · Galenkamp · N. · Bleijenberg · N. · Schoonhoven · L. · Scheepers · F. E. · Crilly · J. · van Veen · M. · Ham · W. H. W.
Introduction

Worldwide, there is an increase in the extent and severity of mental illness. Exacerbation of somatic complaints in this group of people can result in recurring ambulance and emergency department care. The care of patients with a mental dysregulation (ie, experiencing a mental health problem and disproportionate feelings like fear, anger, sadness or confusion, possibly with associated behaviours) can be complex and challenging in the emergency care context, possibly evoking a wide variety of feelings, ranging from worry or pity to annoyance and frustration in emergency care staff members. This in return may lead to stigma towards patients with a mental dysregulation seeking emergency care. Interventions have been developed impacting attitude and behaviour and minimising stigma held by healthcare professionals. However, these interventions are not explicitly aimed at the emergency care context nor do these represent perspectives of healthcare professionals working within this context. Therefore, the aim of the proposed review is to gain insight into interventions targeting healthcare professionals, which minimise stigma including beliefs, attitudes and behaviour towards patients with a mental dysregulation within the emergency care context.

Methods and analysis

The protocol for a systematic integrative review is presented, using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols recommendations. A systematic search was performed on 13 July 2023. Study selection and data extraction will be performed by two independent reviewers. In each step, an expert with lived experience will comment on process and results. Software applications RefWorks-ProQuest, Rayyan and ATLAS.ti will be used to enhance the quality of the review and transparency of process and results.

Ethics and dissemination

No ethical approval or safety considerations are required for this review. The proposed review will be submitted to a relevant international journal. Results will be presented at relevant medical scientific conferences.

Cost-effectiveness analysis of the Geriatric Fracture Center (GFC) concept: a prospective multicentre cohort study

Por: Joeris · A. · Sprague · S. · Blauth · M. · Gosch · M. · Wattanapanom · P. · Jarayabhand · R. · Poeze · M. · Wong · M. K. · Kwek · E. B. K. · Hegeman · J. H. · Perez-Uribarri · C. · Guerado · E. · Revak · T. J. · Zohner · S. · Joseph · D. · Phillips · M. R.
Introduction

Geriatric Fracture Centers (GFCs) are dedicated treatment units where care is tailored towards elderly patients who have suffered fragility fractures. The primary objective of this economic analysis was to determine the cost-utility of GFCs compared with usual care centres.

Methods

The primary analysis was a cost-utility analysis that measured the cost per incremental quality-adjusted life-year gained from treatment of hip fracture in GFCs compared with treatment in usual care centres from the societal perspective over a 1-year time horizon. The secondary analysis was a cost-utility analysis from a societal perspective over a lifetime time horizon. We evaluated these outcomes using a cost-utility analysis using data from a large multicentre prospective cohort study comparing GFCs versus usual care centres that took place in Austria, Spain, the USA, the Netherlands, Thailand and Singapore.

Results

GFCs may be cost-effective in the long term, while providing a more comprehensive care plan. Patients in usual care centre group were slightly older and had fewer comorbidities. For the 1-year analysis, the costs per patient were slightly lower in the GFC group (–$646.42), while the quality-adjusted life-years were higher in the usual care centre group (+0.034). The incremental cost-effectiveness ratio was $18 863.34 (US$/quality-adjusted life-year). The lifetime horizon analysis found that the costs per patient were lower in the GFC group (–$7210.35), while the quality-adjusted life-years were higher in the usual care centre group (+0.02). The incremental cost-effectiveness ratio was $320 678.77 (US$/quality-adjusted life-year).

Conclusions

This analysis found that GFCs were associated with lower costs compared with usual care centres. The cost-savings were greater when the lifetime time horizon was considered. This comprehensive cost-effectiveness analysis, using data from an international prospective cohort study, found that GFC may be cost-effective in the long term, while providing a more comprehensive care plan. A greater number of major adverse events were reported at GFC, nevertheless a lower mortality rate associated with these adverse events at GFC. Due to the minor utility benefits, which may be a result of greater adverse event detection within the GFC group and much greater costs of usual care centres, the GFC may be cost-effective due to the large cost-savings it demonstrated over the lifetime time horizon, while potentially identifying and treating adverse events more effectively. These findings suggest that the GFC may be a cost-effective option over the lifetime of a geriatric patient with hip fracture, although future research is needed to further validate these findings.

Financing networks of care: a cross-case analysis from six countries

Por: Villalobos Dintrans · P. · Roder-DeWan · S. · Wang · H.
Objectives

Describe experiences of countries with networks of care’s (NOCs’) financial arrangements, identifying elements, strategies and patterns.

Design

Descriptive using a modified cross-case analysis, focusing on each network’s financing functions (collecting resources, pooling and purchasing).

Setting

Health systems in six countries: Argentina, Australia, Canada, Singapore, the United Kingdom and the USA.

Participants

Large-scale NOCs.

Results

Countries differ in their strategies to implement and finance NOCs. Two broad models were identified in the six cases: top-down (funding centrally designed networks) and bottom-up (financing individual projects) networks. Despite their differences, NOCs share the goal of improving health outcomes, mainly through the coordination of providers in the system; these results are achieved by devoting extra resources to the system, including incentives for network formation and sustainability, providing extra services and setting incentive systems for improving the providers’ performance.

Conclusions

Results highlight the need to better understand the financial implications and alternatives for designing and implementing NOCs, particularly as a strategy to promote better health in low- and middle-income settings.

Scoping review of African health histories: a protocol

Por: Karamagi · H. C. · Oduwole · E. O. · Sy · S. · Adamu · A. A. · Seydi · A. B. W. · Wiysonge · C. S.
Introduction

The history of African health is closely entwined with the history of the continent itself—from precolonial times to the present day. A study of African health histories is critical to understanding the complex interplay between social, economic, environmental and political factors that have shaped health outcomes on the continent. Furthermore, it can shed light on the successes and failures of past health interventions, inform current healthcare policies and practices, and guide future efforts to address the persistent health challenges faced by African populations. This scoping review aims to identify existing literature on African health histories.

Methods and analysis

The Arksey and O’Malley’s framework for conducting scoping reviews will be utilised for the proposed review, which will be reported in compliance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. The main review question is ‘What literature exists on the history of health practices and healthcare delivery systems in Africa from the precolonial era through to the sustainable development goal era?’ Keywords such as Africa, health and histories will be used to develop a search strategy to interrogate selected databases and grey literature repositories such as PubMed, Scopus, Web of Science and WHOLIS. Two authors will independently screen titles and abstracts of retrieved records. One author will extract data from articles that meet the inclusion criteria using a purposively designed data charting. The data would be coded and analysed thematically, and the findings presented narratively.

Ethics and dissemination

The scoping review is part of a larger project which has approval from the WHO AFRO Ethics Research Committee (Protocol ID: AFR/ERC/2022/11.3). The protocol and subsequent review will be submitted to the integrated African Health Observatory and published in a peer-reviewed journal.

The BREAK study protocol: Effects of intermittent energy restriction on adaptive thermogenesis during weight loss and its maintenance

by Filipa M. Cortez, Catarina L. Nunes, Luís B. Sardinha, Analiza M. Silva, Vítor H. Teixeira

Background

Adaptive thermogenesis, defined as the decrease in the energy expenditure components beyond what can be predicted by changes in body mass stores, has been studied as a possible barrier to weight loss and weight maintenance. Intermittent energy restriction (IER), using energy balance refeeds, has been pointed out as a viable strategy to reduce adaptive thermogenesis and improve weight loss efficiency (greater weight loss per unit of energy deficit), as an alternative to a continuous energy restriction (CER). Following a randomized clinical trial design, the BREAK Study aims to compare the effects of IER versus CER on body composition and in adaptive thermogenesis, and understand whether participants will successfully maintain their weight loss after 12 months.

Methods

Seventy-four women with obesity and inactive (20–45 y) will be randomized to 16 weeks of CER or IER (8x2 weeks of energy restriction interspersed with 7x1 week in energy balance). Both groups will start with 2 weeks in energy balance before energy restriction, followed by 16 weeks in energy restriction, then 8 weeks in energy balance and finally a 12-month weight maintenance phase. Primary outcomes are changes in fat-mass and adaptive thermogenesis after weight loss and weight maintenance. Secondary outcomes include weight loss, fat-free mass preservation, alterations in energy expenditure components, and changes in hormones (thyroid function, insulin, leptin, and cortisol).

Discussion

We anticipate that The BREAK Study will allow us to better understand adaptive thermogenesis during weight loss and weight maintenance, in women with obesity. These findings will enable evidence-based decisions for obesity treatment.

Design and evaluation of a digital health intervention with proactive follow-up by nurses to improve healthcare and outcomes for patients with breast cancer in Mexico: protocol for a randomised clinical trial

Introduction

Nearly 30 000 Mexican women develop breast cancer annually, frequently presenting unmet supportive care needs. In high-income countries, incorporating electronic patient-reported outcomes (ePROs) into cancer care has demonstrated potential for increasing patient-centred care and reducing unmet needs. No such ePRO interventions have been implemented in Mexico. This paper presents the study protocol for designing and evaluating an ePRO digital health application combined with proactive follow-up by nurses.

Methods and analysis

We designed a two-component intervention for women receiving breast cancer treatment: a responsive web application for monitoring ePROs and clinical algorithms guiding proactive follow-up by nurses. We will conduct a pilot test of the intervention with 50 patients with breast cancer for 6 weeks to assess feasibility and adjust the application. We will conduct a parallel arm randomised controlled trial assigning 205 patients each to intervention and control in one of Mexico’s largest public oncology hospitals. The intervention will be provided for 6 months, with additional 3 months of post-intervention observation. The control group will receive usual healthcare and a list of breast cancer information sources. Women diagnosed with stages I, II or III breast cancer who initiate chemotherapy and/or radiotherapy will be invited to participate. The primary study outcome will be supportive care needs; secondary outcomes include global quality of life and breast symptoms. Information on the outcomes will be obtained through web-based self-administered questionnaires collected at baseline, 1, 3, 6 and 9 months.

Ethics and dissemination

The National Research and Ethics Committees of the Mexican Institute of Social Security approved the study (R-2021-785-059). Participants will sign an informed consent form prior to their inclusion. Findings will be disseminated through a policy brief to the local authorities, a webinar for patients, publications in peer-reviewed journals and presentations at national and international conferences.

Long-term follow-up study of work status among patients with work-related mental disorders referred to departments of occupational medicine in Denmark

Por: Kyndi · M. · Willert · M. V. · Vestergaard · J. M. · Andersen · J. H. · Christiansen · D. H. · Dalgaard · V. L.
Objectives

To describe the 5 year work status in patients referred for suspected work-related common mental disorders. To develop a prognostic model.

Design

Register-based nationwide longitudinal follow-up study.

Setting

All departments of occupational medicine in Denmark.

Participants

17 822 patients aged 18–67 years, seen for the first time at a Department of Occupational Medicine in Denmark from 2000 to 2013 and diagnosed with stress, depression, post-traumatic stress disorder, anxiety or other mental disorders.

Interventions

All patients were seen for diagnostic assessment and causal evaluation of the work-relatedness of their disorders. Some departments offered patients with stress disorders psychological treatment, which, however, was not organised according to patient selection or type of treatment.

Primary and secondary outcome measures

Register data were collected for 5 year periods before and after the patients’ first assessment at a department. Weekly percentages of patients are presented according to work status. The outcome in the prognostic model was a high Work Participation Score (ie, working>75% of potential work weeks/year) at 5 year follow-up.

Results

For all subgroups of patients, a high proportion were working (>75%) 1–5 years before assessment, and all experienced a large reduction in work status at time of assessment. At 1 year follow-up, almost 60% of patients with stress were working, whereas in the other patient subgroups, less than 40% were working. In the following years, practically no increase was observed in the percentage of patients working in any of the subgroups. Based on these 5 year follow-up data, we developed a work participation model with only moderate discrimination and calibration.

Conclusions

In Denmark, not all return to previous work status 5 years after a referral due to a suspected work-related common mental disorder. We developed a prognostic model with only moderate discrimination and calibration for long-term work participation after suggested work-related common mental disorders.

Relationship between self-reported listening and communication difficulties and executive function: a protocol for a systematic review and meta-analysis

Por: Stacey · J. E. · Danielsson · H. · Heinrich · A. · Batinovic · L. · Holmer · E. · Ingo · E. · Henshaw · H.
Introduction

Listening and communication difficulties can limit people’s participation in activity and adversely affect their quality of life. Hearing, as well as listening and communication difficulties, can be measured either by using behavioural tests or self-report measures, and the outcomes are not always closely linked. The association between behaviourally measured and self-reported hearing is strong, whereas the association between behavioural and self-reported measures of listening and communication difficulties is much weaker, suggesting they assess different aspects of listening. While behavioural measures of listening and communication difficulties have been associated with poorer cognitive performance including executive functions, the same association has not always been shown for self-report measures. The objective of this systematic review and meta-analysis is to understand the relationship between executive function and self-reported listening and communication difficulties in adults with hearing loss, and where possible, potential covariates of age and pure-tone audiometric thresholds.

Methods and analysis

Studies will be eligible for inclusion if they report data from both a self-report measure of listening difficulties and a behavioural measure of executive function. Eight databases are to be searched: MEDLINE (via Ovid SP), EMBASE (via Ovid SP), PsycINFO (via Ovid SP), ASSIA (via ProQuest), Cumulative Index to Nursing and Allied Health Literature or CINAHL (via EBSCO Host), Scopus, PubMed and Web of Science (Science and Social Science Citation Index). The JBI critical appraisal tool will be used to assess risk of bias for included studies. Results will be synthesised primarily using a meta-analysis, and where sufficient quantitative data are not available, a narrative synthesis will be carried out to describe key results.

Ethics and dissemination

No ethical issues are foreseen. Data will be disseminated via academic publication and conference presentations. Findings may also be published in scientific newsletters and magazines.

Child eye health in Ethiopia: a mixed methods analysis of policy and commitment to action

Por: Sherief · S. T. · Tesfaye · S. · Eshetu · Z. · Ali · A. · Dimaras · H.
Background

Child eye health is a serious public health issue in Ethiopia, where children under the age of 15 account for over half of the population. Our aim was to review Ethiopian health policy and practice to reveal approaches and commitment to promotion and delivery of child eye health services.

Methods

We conducted a mixed-methods situational analysis employing documentary analysis and key informant interview methods. Government publications touching on any element of child eye health were included. Key informants were eligible if they were leaders, authorities, researchers or clinicians involved in child health. Data was combined and analysed by narrative synthesis, using an adaptation of the Eye Care Situation Analysis Tool as a framework.

Findings

Eleven documents developed by the Ministries of Health and Education were included and interviews with 14 key informants were conducted. A focus on child eye health was lacking in key health policy documents, demonstrated by limited allocation of funds, a shortage of human resources, and a subpar referral system across all levels of child eye care.

Conclusion

The study identified several gaps and limitations in child eye health in Ethiopia. There is a need for health policies that strengthen ownership, finance and partnerships for improved coordination, and collaboration with line ministries and other stakeholders to improve child eye health services in Ethiopia.

Clinician and patient perspectives on the barriers and facilitators to physical rehabilitation in intensive care: a qualitative interview study

Por: Woodbridge · H. R. · Norton · C. · Jones · M. · Brett · S. J. · Alexander · C. M. · Gordon · A. C.
Objectives

The objective of this study is to explore patient, relative/carer and clinician perceptions of barriers to early physical rehabilitation in intensive care units (ICUs) within an associated group of hospitals in the UK and how they can be overcome.

Design

Qualitative study using semi-structured interviews and thematic framework analysis.

Setting

Four ICUs over three hospital sites in London, UK.

Participants

Former ICU patients or their relatives/carers with personal experience of ICU rehabilitation. ICU clinicians, including doctors, nurses, physiotherapists and occupational therapists, involved in the delivery of physical rehabilitation or decisions over its initiation.

Primary and secondary outcomes measures

Views and experiences on the barriers and facilitators to ICU physical rehabilitation.

Results

Interviews were carried out with 11 former patients, 3 family members and 16 clinicians. The themes generated related to: safety and physiological concerns, patient participation and engagement, clinician experience and knowledge, teamwork, equipment and environment and risks and benefits of rehabilitation in intensive care. The overarching theme for overcoming barriers was a change in working model from ICU clinicians having separate responsibilities (a multidisciplinary approach) to one where all parties have a shared aim of providing patient-centred ICU physical rehabilitation (an interdisciplinary approach).

Conclusions

The results have revealed barriers that can be modified to improve rehabilitation delivery in an ICU. Interdisciplinary working could overcome many of these barriers to optimise recovery from critical illness.

Danish Prostate Cancer Consortium Study 1 (DPCC-1) protocol: Multicentre prospective validation of the urine-based three-microRNA biomarker model uCaP

Por: Fredsoe · J. · Glud · E. · Boesen · L. · Logager · V. · Poulsen · M. H. · Pedersen · B. G. · Borre · M. · Sorensen · K. D.
Introduction

The primary objective of the Danish Prostate Cancer Consortium Study 1 (DPCC-1) is to provide validation for a novel urine-based microRNA biomarker, called uCaP, for a diagnosis of prostate cancer.

Methods and analysis

Eligible participants are biopsy naïve men aged ≥18 years with prostate-specific antigen (PSA) levels ≥3 ng/mL, who are referred to prostate MRI due to suspicion of PC at one of the following three major urology/uroradiology centers: Aarhus University Hospital, Herlev & Gentofte University Hospital, or Odense University Hospital, where MRI and targeted biopsy are implemented in clinical use. Exclusion criteria include previous diagnosis of urogenital cancer, contraindication to MRI, gender reassignment treatment or PSA level >20 ng/mL. The participants will be asked to donate a urine sample in connection with their MRI. The study is observational, uses a diagnostic accuracy testing setup and will integrate into the current diagnostic pathway.

We will measure the levels of the three microRNAs in the uCaP model (miR-222–3 p, miR-24–3 p and miR-30c-5p) in extracellular vesicle-enriched cell-free urine samples, to assess if uCaP can improve specificity and retain sensitivity for International Society of Urological Pathology Grade Group ≥2 PC, when used as a reflex test to PSA ≥3 ng/mL. We hypothesise that uCaP can improve selection for prostate MRI and reduce the number of unnecessary scans and biopsies.

Ethics and dissemination

This study is approved by the Central Denmark Region Committee on Health Research Ethics (reference number: 1-10-72-85-22). All participants will provide written informed consent. Study results will be published in peer-reviewed journals and presented in scientific meetings.

Implementing paediatric patient-reported outcome measures in outpatient asthma clinics: a feasibility assessment study

Por: Bele · S. · Paolucci · E. O. · Johnson · D. W. · Quan · H. · Santana · M.-J.
Objective

Implementation of patient-reported outcome measures (PROMs) is limited in paediatric routine clinical care. The KidsPRO programme has been codesigned to facilitate the implementation of PROMs in paediatric healthcare settings. Therefore, this study (1) describes the development of innovative KidsPRO programme and (2) reports on the feasibility of implementing PedsQL (Pediatric Quality of Life Inventory) PROM in asthma clinics using the KidsPRO programme.

Design

Feasibility assessment study.

Setting

Outpatient paediatric asthma clinics in the city of Calgary, Canada.

Participants

Five paediatric patients, four family caregivers and three healthcare providers were recruited to pilot the implementation of PedsQL PROM using KidsPRO. Then, a survey was used to assess its feasibility among these study participants.

Main outcome measures

Participants’ understanding of using PROMs, the adequacy of support provided to them, the utility of using PROMs as part of their appointment, and their satisfaction with using PROMs.

Analyses

The quantitative data generated through closed-ended questions was analysed and represented in the form of bar charts for each category of study participants (ie, patients, their family caregivers and healthcare providers). The qualitative data generated through the open-ended questions were content analysed and categorised into themes.

Results

The experience of using PROMs was overwhelmingly positive among patients and their family caregivers, results were mixed among healthcare providers. Qualitative data collected through open-ended questions also complemented the quantitative findings.

Conclusion

The evidence from this study reveals that the implementation of PROMs in routine paediatric clinical care asthma clinics in Alberta is seems to be feasible.

Impact of a short online course on the accuracy of non-ophthalmic diabetic retinopathy graders in recognising glaucomatous optic nerves in Vietnam

Por: Olawoye · O. O. · Ha · T. H. · Pham · N. · Nguyen · L. · Cherwek · D. H. · Fowobaje · K. R. · Ross · C. · Coote · M. · Chan · V. F. · Kahook · M. · Peto · T. · Azuara-Blanco · A. · Congdon · N.
Purpose

To test an online training course for non-ophthalmic diabetic retinopathy (DR) graders for recognition of glaucomatous optic nerves in Vietnam.

Methods

This was an uncontrolled, experimental, before-and-after study in which 43 non-ophthalmic DR graders underwent baseline testing on a standard image set, completed a self-paced, online training course and were retested using the same photographs presented randomly. Twenty-nine local ophthalmologists completed the same test without the training course. DR graders then underwent additional one–to-one training by a glaucoma specialist and were retested. Test performance (% correct, compared with consensus grades from four fellowship-trained glaucoma experts), sensitivity, specificity, positive and negative predictive value, and area under the receiver operating (AUC) curve, were computed.

Results

Mean age of DR graders (32.6±5.5 years) did not differ from ophthalmologists (32.3±7.3 years, p=0.13). Online training required a mean of 297.9 (SD 144.6) minutes. Graders’ mean baseline score (33.3%±14.3%) improved significantly after training (55.8%±12.6%, p

Conclusion

Non-ophthalmic DR graders can be trained to recognise glaucoma using a short online course in this setting, with no additional benefit from more expensive one–to-one training. After 5-hour online training in recognising glaucomatous optic nerve head, scores of non-ophthalmic DR graders doubled, and did not differ from local ophthalmologists. Intensive one-to-one training did not further improve performance

Interventions to treat patients with blood blister-like aneurysms of the internal carotid artery: a protocol for a network meta-analysis

Por: Li · Y. · Yang · X. · Zhou · H. · Li · H. · Zheng · J. · Li · L. · Hui · X.
Introduction

Blood blister-like aneurysm (BBA) is a special type of intracranial aneurysm with relatively low morbidity and high mortality. Various microsurgical techniques and endovascular approaches have been reported, but the optimal management remains controversial. For a better understanding of the treatment of BBA patients, a network meta-analysis that comprehensively compares the effects of different therapies is necessary.

Methods and analysis

This protocol has been reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Related studies in the following databases will be searched until November 2022: PubMed, Embase, Scopus, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP and Wanfang. Randomised controlled trials (RCTs) and non-randomised studies comparing at least two different interventions in BBA patients will be included. Quality assessment will be conducted using Cochrane Collaboration’s tool or Newcastle-Ottawa Scale based on their study designs. The primary outcome is the composite of the incidences of intraoperative bleeding, postoperative bleeding and postoperative recurrence. The secondary outcome is an unfavourable functional outcome. Pairwise and network meta-analyses will be conducted using STATA V.14 (StataCorp, College Station, Texas, USA). Mean ranks and the surface under the cumulative ranking curve will be used to evaluate every intervention. Statistical inconsistency assessment, subgroup analysis, sensitivity analysis and publication bias assessment will be performed.

Ethics and dissemination

Ethics approval is not necessary because this study will be based on publications. The results of this study will be published in a peer-reviewed journal.

Cohort profile: the U-BIRTH study on peripartum depression and child development in Sweden

Por: Tu · H.-F. · Fransson · E. · Kunovac Kallak · T. · Elofsson · U. · Ramklint · M. · Skalkidou · A.
Purpose

The current U-BIRTH cohort (Uppsala Birth Cohort) extends our previous cohort Biology, Affect, Stress, Imaging and Cognition (BASIC), assessing the development of children up to 11 years after birth. The U-BIRTH study aims to (1) assess the impact of exposure to peripartum mental illness on the children’s development taking into account biological and environmental factors during intrauterine life and childhood; (2) identify early predictors of child neurodevelopmental and psychological problems using biophysiological, psychosocial and environmental variables available during pregnancy and early post partum.

Participants

All mothers participating in the previous BASIC cohort are invited, and mother–child dyads recruited in the U-BIRTH study are consecutively invited to questionnaire assessments and biological sampling when the child is 18 months, 6 years and 11 years old. Data collection at 18 months (n=2882) has been completed. Consent for participation has been obtained from 1946 families of children having reached age 6 and from 698 families of children having reached age 11 years.

Findings to date

Based on the complete data from pregnancy to 18 months post partum, peripartum mental health was significantly associated with the development of attentional control and gaze-following behaviours, which are critical to cognitive and social learning later in life. Moreover, infants of depressed mothers had an elevated risk of difficult temperament and behavioural problems compared with infants of non-depressed mothers. Analyses of biological samples showed that peripartum depression and anxiety were related to DNA methylation differences in infants. However, there were no methylation differences in relation to infants’ behavioural problems at 18 months of age.

Future plans

Given that the data collection at 18 months is complete, analyses are now being undertaken. Currently, assessments for children reaching 6 and 11 years are ongoing.

Investigating the ability to adhere to cardiometabolic medications with different properties: a retrospective cohort study of >500 000 patients in the USA

Por: Lauffenburger · J. C. · Tesfaye · H. · Solomon · D. H. · Antman · E. M. · Glynn · R. J. · Lee · S. B. · Tong · A. · Choudhry · N. K.
Objective

Poor medication adherence remains highly prevalent and adversely affects health outcomes. Patients frequently describe properties of the pills themselves, like size and shape, as barriers, but this has not been evaluated objectively. We sought to determine the extent to which oral medication properties thought to be influential translate into lower objectively-measured adherence.

Design

Retrospective cohort study.

Setting

US nationwide commercial claims database, 2016–2019.

Participants

Among patients initiating first-line hypertension, diabetes or hyperlipidaemia treatment based on clinical guidelines, we measured pill size, shape, colour and flavouring, number of pills/day and fixed-dose combination status as properties.

Outcome measures

Outcomes included discontinuation after the first fill (ie, never filling again over a minimum of 1-year follow-up) and long-term non-adherence (1-year proportion of days covered

Results

Across 604 323 patients, 14.6% discontinued after filling once (ie, were non-persistent), and 54.0% were non-adherent over 1-year follow-up. Large pill size was associated with non-adherence, except for thiazides (eg, metformin adjusted OR (aOR): 1.12, 95% CI: 1.06 to 1.18). Greater pill burden was associated with a higher risk of non-adherence across all classes (eg, metformin aOR: 1.58, 95% CI: 1.53 to 1.64 for two pills/day). Taking less than one pill/day was also associated with higher risk of non-adherence and non-persistence (eg, non-persistence statin aOR: 1.29, 95% CI: 1.20 to 1.38). Pill shape, colour, flavouring and combination status were associated with mixed effects across classes.

Conclusions

Pill burden and pill size are key properties affecting adherence for almost all classes; others, like size and combination, could modestly affect medication adherence. Clinical interventions could screen patients for potential intolerance to medication and potentially implement more convenient dosing schedules.

Objectives

In this study, we aimed to identify the causes, predictors and gender disparities of 30-day and 90-day cardiovascular readmissions after COVID-19-related hospitalisations using National Readmission Database (NRD) 2020.

Setting

We used the NRD from 2020 to identify hospitalised adults with a principal diagnosis of COVID-19 infection.

Participants

We included subjects who were readmitted within 30 days and 90 days after index admission. We excluded subjects with elective and traumatic admissions. We used a multivariate Cox regression model to identify independent predictors of readmission.

Primary and secondary outcomes measures

Our outcomes were inpatient mortality, 30-day and 90-day cardiovascular readmission rates following COVID-19 infection.

Results

During the study period, there were 1 024 492 index hospitalisations with a primary diagnosis of COVID-19 infection in the 2020 NRD database, 644 903 (62.9%) were included for 30-day readmission analysis, and 418 122 (40.8%) were included for 90-day readmission analysis. Of patients involved in the 30-day analysis, 7140 (1.1%) patients had a readmission within 30 days; of patients involved in the 90-day analysis, 8379 (2.0%) had a readmission within 90 days due to primarily cardiovascular causes. Cox regression analysis revealed that the female sex (aHR 0.89; 95% CI 0.82 to 0.95; p=0.001) was associated with a lower hazard of 30-day cardiovascular readmissions; however, congestive heart failure (aHR 2.45; 95% CI 2.2 to 2.72; p

Conclusion

Our study demonstrates that male gender, heart failure, arrhythmias and valvular disease carry higher hazards of 30-day and 90-day cardiovascular readmissions. Identifying risk factors and common causes of readmission may assist with lowering the burden of cardiovascular disease in patients with COVID-19 infection.

'They say: medical students perceptions of General Practice, experiences informing these perceptions, and their impact on career intention--a qualitative study among medical students in England

Por: Banner · K. · Alberti · H. · Khan · S. A. · Jones · M. M. · Pope · L. M.
Objectives

The number of UK graduates choosing General Practice training remains significantly lower than the current numbers required to meet the demands of the service. This work aims to explore medical students’ perceptions of General Practice, experiences which lead to the development of these perceptions, and the ultimate impact of these on career intention.

Design

This mixed-methods, qualitative study used focus groups, semistructured interviews, longitudinal audio diary data and debrief interviews to explore and capture the experiences and perceptions of students in their first and penultimate years of university.

Setting

Three English medical schools.

Participants

Twenty students were recruited to focus groups from first and fourth/fifth year of study. All students in these years of study were invited to attend. Six students were recruited into the longitudinal diary study to further explore their experiences.

Results

This work identified that external factors, internal driving force and the ‘they say’ phenomenon were all influential on the development of perceptions and ultimately career intention. External factors may be split into human or non-human influences, for example, aspirational/inspirational seniors, family, peers (human), placements and ‘the push’ of GP promotion (non-human). Driving force refers to internal factors, to which the student compares their experiences in an ongoing process of reflection, to understand if they feel General Practice is a career they wish to pursue. The ‘they say’ phenomenon refers to a passive and pervasive perception, without a known source, whereby usually negative perceptions circulate around the undergraduate community.

Conclusion

Future strategies to recruit graduates to General Practice need to consider factors at an undergraduate level. Positive placement experiences should be maximised, while avoiding overtly ‘pushing’ GP onto students.
