Accurate estimates of the burden of vaccine-preventable community-acquired pneumonia (CAP) hospitalisations both overall and due to the most frequent and vaccine-preventable pathogens are needed to inform the use of respiratory vaccines in adults.

This was a prospective, population-based CAP surveillance study at three hospitals in Germany. All patients admitted with clinically suspected CAP were tested for Streptococcus pneumoniae using urine antigen tests and for respiratory syncytial virus (RSV), influenza virus and SARS-CoV-2 using multiplex PCR from nasopharyngeal swabs. Incidence rate calculations for all-cause CAP were based on eligible patients, regardless of enrolment status.

Individuals admitted to study hospitals within the surveillance period with suspected or confirmed diagnosis of pneumonia who provided informed consent.

Radiologically confirmed (RAD) CAP.

Active surveillance between 1 January 2021 and 30 June 2023 identified at the three study sites 4319 adults with RAD-CAP that met eligibility criteria, of which 1479 (34.2%) were enrolled and included in the analysis for pathogen distribution. The main reason for non-enrolment was the inability to provide informed consent. Incidence estimates were based on 1254 study-eligible individuals admitted at the largest study site. SARS-CoV-2, S. pneumoniae, RSV or influenza were identified in 36.5%, 9.1%, 3.7% and 1.8% of patients with RAD-CAP, respectively. Serotypes included in the 20-valent pneumococcal conjugate vaccine were detected in 6.9% of RAD-CAP and 76.0% of pneumococcal CAP. The overall adjusted annual incidence of all-cause RAD-CAP over the study period was 490/100 000 (95% CI 461 to 521). The incidence of pneumococcal and RSV-related RAD-CAP increased 8.6-fold and 10.0-fold over the study period, resulting in an incidence of 60/100 000 (95% CI 45 to 75) and 30/100 000 (95% CI 19 to 41) in 2022/2023, respectively, while SARS-CoV-2 related RAD-CAP declined by 70% to 97/100 000 (95% CI 78 to 116).

Active pneumonia surveillance reported a high burden of RAD-CAP hospitalisations in Germany, especially among older adults. The resurgence of CAP due to RSV, S. pneumoniae or influenza, alongside maintained activity of SARS-CoV-2, was associated with an overall increase of RAD-CAP among adults.

Despite several intensive interventions, HIV remains a major public health challenge affecting many individuals worldwide and highlighting ongoing gaps in HIV testing.

To assess the proportion of ‘never been tested for HIV’ and the risk factors associated therewith among women aged 15–49 years.

The 2022 Tanzania Demographic and Health Survey data were used for this study. The variable of interest was whether women of reproductive age (WRA) reported never being tested for HIV. A total weighted sample of 15 254 WRA participated in the study. A survey logistic regression model was employed to determine factors associated with never being tested for HIV, as it accounts for the complexity of the sampling design. Analysis was performed at a 5% level of significance using R statistical software V. 4.5.2.

Of the 15 254 WRA that participated, 3082 (20.2%) reported never being tested for HIV. The median (IQR) age of participants was 28 (21–37) years. The odds of never being tested for HIV decreased with increasing age (OR=0.96; 95% CI 0.95 to 0.97). Furthermore, factors such as having primary or secondary education, being pregnant or breastfeeding, marital status (married, living with a partner, widowed, divorced or separated), living in a female-headed household, using the internet, abstaining from sex, being aware of HIV test kits but never using them, media exposure, belonging to the middle wealth index category, using contraceptives and having other sexual partners besides a spouse within the past 12 months was found to be associated with never being tested for HIV among WRA in Tanzania.

This current study identified several factors associated with never being tested for HIV among WRA. To enhance HIV testing uptake in this population, government and public health stakeholders should design targeted interventions that address these determinants, particularly by improving access to education, promoting health awareness and integrating HIV testing into routine reproductive health services.

Administering supplemental oxygen to prevent hypoxaemia is a fundamental treatment for patients hospitalised with acute injury or illness. However, the amount of oxygen administered frequently exceeds that needed to maintain normoxaemia, causing patients to experience hyperoxaemia and wasting supplemental oxygen. Closed-loop, autonomous oxygen titration systems are designed to optimise oxygen delivery by administering the lowest possible oxygen flow that maintains peripheral oxygen saturation (SpO₂) within a predefined range. For adults hospitalised with an acute injury or illness, it remains uncertain whether the use of a closed-loop, autonomous oxygen titration system safely increases the proportion of time spent in normoxaemia (SpO₂ 90%–96%) compared with usual care.

The Strategy to Avoid Excessive Oxygen using Autonomous Oxygen Titration Intervention trial is a multicentre, unblinded, parallel-group, randomised trial being conducted at four level 1 trauma centres in the USA. The trial compares an autonomous oxygen titration system versus usual care among 300 adults hospitalised for major trauma, burn, acute care surgery or acute respiratory illness. The primary outcome is the proportion of patient-time spent within the targeted normoxaemia range (SpO₂ 90%–96%) as measured by continuous non-invasive pulse oximetry, during the first 72 hours after randomisation. Secondary outcomes include the amount of supplemental oxygen administered and the proportion of time spent in hypoxaemia (SpO₂2 >96%). Specifying the protocol and statistical analysis plan before the conclusion of enrolment increases the rigour, reproducibility and interpretability of the trial. Enrolment began on 6 May 2024.

The trial protocol was approved by the single institutional review board at the University of Colorado School of Medicine and the Office of Human Research Oversight at the Department of Defense. We will present the results at scientific conferences and submit them for publication in a peer-reviewed journal.

NCT06374225.

We surveyed authors of publications in high-impact psychiatry journals to assess the (1) proportion that disseminated results to study participants or others with lived experience, and, among those who disseminated, (2) methods (eg, email) and (3) tools (eg, plain-language summary) used.

Meta-research review.

PubMed search on 14 December 2022 and emails to study authors for information on dissemination.

Eligible studies collected primary human data and were published in psychiatry journals with 2021 impact factor ≥10.

Study information was extracted by one investigator and validated by a second investigator, with conflicts resolved by consensus, with a third investigator consulted as necessary. We emailed authors approximately 2 years post-publication to ensure sufficient time had passed to share results. We estimated the proportion of authors that may have disseminated results to participants or others with lived experience, assuming that non-respondents (1) did not disseminate, (2) were half as likely to disseminate as respondents or (3) disseminated in the same proportion as respondents.

Of 141 studies, 94 (67%) authors responded. Among respondents, 21 (22%) reported disseminating to study participants, and an additional 9 (10%) reported disseminating lay materials to people with lived experience (total of 30 studies, 32%). Overall, we estimated that 15% (95% CI 10% to 22%) to 23% (95% CI 17% to 30%) of authors may have disseminated results directly to study participants and 21% (95% CI 15% to 29%) to 32% (95% CI 25% to 40%) to participants or others with lived experience. Among the 30 that reported disseminating, the most common methods were sending mail or emails to study participants (17 studies, 57%) and posting on social media (15 studies, 50%). The most common tools were plain-language summaries (22 studies, 73%) and webinars or other meetings (15 studies, 50%).

Dissemination of results to participants in mental health research is uncommon. Funding agencies, ethics committees, journals and academic institutions should support dissemination.

There is a global rise in the burden of childhood obesity, increasing the risk of early onset adult obesity. Most developing countries face the double burden of malnutrition; overnutrition as overweight/obesity and undernutrition.

To determine the current burden and determinants of childhood thinness, overweight and obesity using national survey data.

Data from a cross-sectional survey conducted in 2022 were used.

Data from the seventh Demographic Health Survey conducted in Ghana were used.

The participants included 4417 children ≤59 months.

The seventh Ghana Demographic Health Survey in 2022 employed a two-stage stratified cluster sampling design, selecting 618 clusters to create a nationally representative sample. Weight and height were measured using the SECA 874U scale and Shorrboard, respectively. Children’s heights were measured recumbent (24 months). Multivariate logistic regression was used to assess the relationship between thinness and obesity, as well as the independent factors.

The outcome variable was obesity, determined by a WHZ of >+2SD.

The weighted prevalence of overweight/obesity and thinness in children under 5 years is 9.9% and 5.2%, respectively. Children who were overweight or obese had a mean age of 23.11 months, those who were thin or severely thin had a lower mean age of 21.02 months, and those with normal nutritional status were relatively older, with a mean age of 28.41 months. The Upper West, Northeast and Northern regions had the lowest densities of obesity. In the multivariate logistic regression model, children residing in Ashanti, Oti, Northern, North East and Upper East regions had significantly reduced odds of being obese compared with those in the Ahafo region. The average haemoglobin for those overweight/obese was 10.8 g/dL, and 10.7 g/dL for those who were normal and marginally reduced, 10.5 g/dL for those who were thin.

Regional disparities, maternal nutritional status, socioeconomic conditions and unsafe water sources were significant determinants of child nutrition outcomes. These findings call for targeted, multipronged interventions that integrate maternal-child nutrition, safe water, sanitation and regional context.

Health literacy (HL) is essential for making informed health-related decisions, for example enabling parents to reduce their child’s allergy risk. Health literacy does not, however, rely solely on an individual’s capacities, but is strongly influenced by external factors. Midwives provide important health advice to families, particularly since their relationship is close during a time of significant transition. This offers them a unique opportunity to positively influence the HL of parents, which in turn may support the health and well-being of the whole family. The aim of this study is to develop and evaluate an intervention that can support midwives in providing allergy prevention advice in a way that is in line with the concept of HL.

In accordance with the recommendations of the Medical Research Council framework in the first phase of this study, we will survey midwives (target sample size=379) in Germany regarding their practices, the potential barriers they face and enabling factors in providing advice on early childhood allergy prevention in an HL-responsive way. The data will be subjected to descriptive statistical analysis. Two co-design workshops will then be conducted with various stakeholders in two regions (Rhineland-Palatinate and Saxony) of Germany. Following the protocol proposed by the Stanford Design Thinking School, we will use design thinking to collect ideas for the intervention. Based on these ideas and our previous qualitative and quantitative study, we will develop an intervention in collaboration with didactic experts. The intervention will be piloted in three groups (midwives=10–15, midwives working as practice supervisors=5–10, students of midwifery=10–20). For the process evaluation, we will use observation protocols of the intervention conduct and qualitative interviews. For the outcome evaluation, we will use a questionnaire and observations in simulation laboratories with students of midwifery.

This study protocol was approved by the Ethics Committee of the University of Regensburg (ID 23-3441-101) and is in compliance with the Declaration of Helsinki. Participation in the study will only be possible after informed consent has been given. Our results will be presented at national and international conferences and published in scientific journals. Additionally, once it has been finalised, we will make the intervention available to educational institutions for (future) midwives.

Barcode medication administration (BCMA) systems are increasingly being implemented in hospital settings, with the aim of decreasing medication administration errors. However, the majority of the literature demonstrating the value of BCMA in supporting patient safety is from the USA. Furthermore, little is known about the underlying mechanisms that support its use. This study aims to explore the impact of BCMA on patient safety including medication admisntration errors and nursing time spent providing direct patient care, in terms of what works, for whom, under what circumstances, and how.

We will use a mixed-methods realist evaluation. The study will be conducted in four phases, at two London NHS teaching trusts and one South West Region NHS Trust using different electronic health record systems. Phase 1 will involve documentary analysis and a narrative review to develop an initial programme theory for how BCMA is expected to work. Phase 2 will use interviews with key informants to refine this programme theory. The programme theory will then be tested in phase 3 using mixed methods: (1) observation of nurses’ medication administration; (2) analysis of alert data from the BCMA systems to understand the alerts’ clinical significance and utility and (3) interviews with nurses and hospital inpatients to explore their views. These data will be triangulated to refine and finalise the programme theory in phase 4, together with recommendations for practice.

The Study Coordination Centre has obtained approval (24/SC/0326) from the Oxford B NHS Research Ethics Committee and the Health Research Authority. The study’s findings will be presented at scientific meetings and published in peer-reviewed journals. Additionally, summaries of the findings will be produced, targeted at relevant groups such as healthcare professionals, policy-makers and study participants.

To compare international substandard and falsified (SF) medicine recall trends from published research papers based on governmental databases, summarise the extent of the problem in the legitimate supply chain, and identify ways to manage the issue.

Systematic review of published academic evidence.

Drug recall data in published literature, obtained from official international government regulator databases in the USA, the UK, Canada, Sri Lanka, Zambia, Portugal, Nepal, Saudi Arabia, Argentina, Brazil, Chile, Cuba, Colombia, Mexico, Bolivia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Panama, Peru and Venezuela.

A search for literature published between 2010 and 2024 was conducted using PubMed, MEDLINE and Embase. Included studies examined recall data of substandard and/or falsified medicines obtained through official government regulator websites.

Data were extracted using Excel files and synthesised using a thematic analysis approach.

13 research papers containing original data were included. Recall data were obtained from official regulatory databases in 23 different countries. Substandard medicines had significantly higher recall rates than falsified products, while parenteral drugs and tablets were the most recalled formulation types. The leading reasons for defective medicines were contamination, out-of-specification results, stability and packaging issues. India was identified as a common source of SF medicines in Zambia, Sri Lanka, Brazil and Nepal. Frequent recalls of anti-infective drugs were observed in countries with equatorial, tropical and subtropical climates, while high-income countries like Canada, Saudi Arabia and the UK faced issues with defective antihypertensive drugs. Interestingly, medicines affected by nitrosamines’ contamination were recalled in all regions examined in 2018, but in other recall cases, there were disparities among recall action.

There appeared to be similar international recall practices for some products like nitrosamines and not for others like rosiglitazone across the same time frame, which raises questions concerning international drug safety disparities. The requirement to align and globally strengthen regulatory frameworks was of emerging importance. Cooperation between regulatory authorities to create a harmonised approach to reporting medicine recalls and standardising the data included in a recall notification is proposed to facilitate a more accurate comparison of international trends surrounding recalled SF medicines.

Ovarian cancer remains a significant clinical challenge due to its aggressive nature and high mortality rate. Tumour-infiltrating lymphocytes (TILs) play a critical role in the tumour microenvironment, influencing treatment response and patient survival across various cancer types, including ovarian cancer. A systematic review is warranted to consolidate evidence on TILs as prognostic biomarkers in ovarian cancer, with the goals of integrating them into clinical practice to enhance patient outcomes. This study aims to assess the prognostic significance of TILs in ovarian cancer.

A comprehensive literature search will be conducted across multiple databases, including PubMed, Embase, Web of Science, Scopus, Cochrane Library, CINAHL, ScienceDirect and LILACS. No restrictions regarding publication date or language will be applied. Original studies evaluating the role of TILs in women with ovarian cancer will be considered for inclusion. Two independent authors will screen titles and abstracts, and any discrepancies will be resolved through discussion with a third author. The risk of bias in included studies will be assessed using the Quality in Prognosis Studies (QUIPS) tool. Data synthesis will be performed using R software (V.4.3.1).

This study reviews the published data; thus, obtaining ethical approval is unnecessary. The findings of this systematic review will be published in a peer-reviewed journal.

Thanks to the introduction of recent national guidelines for treating herpes simplex virus (HSV) encephalitis, health outcomes have improved. This paper evaluates the health system costs and the health-related quality of life implications of these guidelines.

A sub-analysis of data from a prospective, multi-centre, observational cohort ENCEPH-UK study conducted across 29 hospitals in the UK from 2012 to 2015.

Data for patients aged ≥16 years with a confirmed HSV encephalitis diagnosis admitted for treatment with aciclovir were collected at discharge, 3 and 12 months.

Patient health outcomes were measured by the Glasgow outcome score (GOS), modified ranking score (mRS) and the EuroQoL; healthcare costs were estimated per patient at discharge from hospital and at 12 months follow-up. In addition, Quality Adjusted Life Years (QALYs) were calculated from the EQ-5D utility scores. Cost–utility analysis was performed using the NHS and Social Care perspective.

A total of 49 patients were included; 35 were treated within 48 hours, ‘early’ (median (IQR) 8.25 [3.7–20.5]) and 14 were treated after 48 hours ‘delayed’ (median (IQR) 93.9 [66.7–100.1]). At discharge, 30 (86%) in the early treatment group had a good mRS outcome score (0–3) compared with 4 (29%) in the delayed group. According to GOS, 10 (29%) had a good recovery in the early treatment group, but only 1 (7%) in the delayed group. EQ-5D-3L utility value at discharge was significantly higher for early treatment (0.609 vs 0.221, p

This study suggests that early treatment may be associated with better health outcomes and reduced patient healthcare costs, with a potential for savings to the NHS with faster treatment.

Paediatric hospitalisation, encompassing the period from admission to discharge, often involves feelings of pain, fear and anxiety, primarily due to clinical diagnoses and, more significantly, discomfort and stress-inducing procedures. Numerous methodologies and interventions have been investigated and implemented to alleviate these phenomena during paediatric hospitalisation. Virtual reality (VR), for example, has demonstrated efficacy in pain relief for hospitalised children in recent studies. This systematic review, therefore, aims to identify and evaluate the effectiveness of VR in alleviating pain, fear and anxiety in hospitalised children undergoing painful procedures.

This systematic review and meta-analysis will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols guidelines. A systematic search will be conducted in March and April 2025 across the following databases, with no restrictions on language or publication year: PubMed, Embase, Scopus, Web of Science, Cumulated Index in Nursing and Allied Health Literature, ClinicalTrials.gov and the Cochrane Central Register of Controlled Trials. Eligible studies will include randomised and quasi-randomised clinical trials involving children (aged 2–10 years) and adolescents (aged 10–18 years) who received VR interventions during painful procedures. Data will be managed and analysed using Review Manager software (RevMan 5.2.3). In cases of significant heterogeneity (I² > 50%), a random-effects model will be employed to combine studies and calculate the OR with a 95% CI. The methodological quality of the included studies will be assessed using the Cochrane Risk of Bias 2.0 tool, and the certainty of the evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluations framework.

This study will solely review published data; thus, ethical approval is not required. This systematic review is expected to provide subsidies, evidence and insights into the use of VR. It is also anticipated that the results will directly impact the improvement of care for these patients and the qualification of professional care.

To assess the incidence of delirium and its predictors among adult patients admitted to the intensive care units of comprehensive specialised hospitals in the Amhara region of northwest Ethiopia from 18 October 2024 to 20 February 2025.

A multicentre prospective observational study was conducted.

Four comprehensive specialised hospitals in the Amhara region of northwest Ethiopia, from 18 October 2024 to 20 February 2025.

A total of 351 patients were included in the final analysis during the study period.

The primary outcome measure of this study was the incidence of delirium. Additionally, the study investigated the factors associated with delirium incidence among adult patients admitted to intensive care units.

The incidence of delirium among adult patients in intensive care units was 42.17% (95% CI: 37.08 to 47.42). Pain (adjusted HR (AHR) = 4.74; 95% CI: 2.38 to 9.44), mechanical ventilation (AHR = 2.96; 95% CI: 1.56 to 5.63), age 65 years or older (AHR = 2.18; 95% CI: 1.48 to 3.21) and agitation (Richmond Agitation-Sedation Scale (RASS) ≥1) (AHR = 3.26; 95% CI: 2.09 to 5.09) were statistically significant factors associated with delirium.

In the present study, more than one-third of patients developed delirium. Pain, mechanical ventilation, age 65 or older and agitation (RASS≥1) were significantly associated with delirium occurrence. To reduce the incidence of delirium, the current study recommends treating or preventing pain and agitation. Additionally, special attention should be given to patients receiving mechanical ventilation and those aged 65 or older during care.

Elevated lipid profiles increase the risk of atherosclerotic cardiovascular disease (ASCVD), a leading cause of mortality worldwide. Despite the availability of lipid-lowering therapy (LLT), adherence to therapy and achievement of Low-Density Lipoprotein Cholesterol (LDL-C) target levels remain suboptimal. Coronary artery disease (CAD) presents substantial public health challenges, with LDL-C goal attainment rates reported to be between 30.0% and 54.0%. The EDHIPO MARCA (Evaluación De adherencia a la terapia HIPOlipemiante en pacientes de Muy Alto Riesgo CArdiovascular) study aims to evaluate LDL-C target achievement among Colombian patients with CAD.

This is a retrospective and multicentre study aiming to evaluate LDL-C target achievement within 12 months of coronary angiography across multiple Colombian institutions. Data will be retrospectively extracted from medical records corresponding to the years 2011, 2012, 2016, 2017, 2021 and 2022, which were selected to correspond with the European Society of Cardiology/European Atherosclerosis Society guideline updates. Inclusion criteria included patients ≥18 years old with confirmed CAD and LDL-C reports recorded during outpatient follow-up. The study will evaluate a minimum sample size of 5000 patients, with data collected through medical records and managed using the REDCap platform. Statistical analyses will be conducted to assess LDL-C target achievement, associated factors and temporal trends using mixed-effects models. Uncertainty will also be explored through sensitivity analysis. The EDHIPO MARCA study will provide key insights into LDL-C target achievement in Colombia, contributing to both regional and global CAD management. Its findings will be used to help shape public health policies and serve as a foundation for future prospective research and interventions aimed at mitigating the burden of cardiovascular disease.

This study was approved by the Comité de Ética en Investigación Biomédica of Fundación Valle del Lili, the coordinating institution and creator of the study protocol. Each participating centre will obtain approval from its local ethics committee prior to data collection. Data will be collected in a de-identified manner, ensuring confidentiality. In accordance with Colombian Resolution 8430, this study is classified as 'no-risk', and informed consent was not required. The findings will be disseminated through scientific events and published in international peer-reviewed journals to contribute to cardiovascular disease management and public health policies.

To explore the opportunities, challenges and perceived strategies for the uptake of OraQuick HIV self-testing (HIVST) among female sex workers in Ethiopia.

A phenomenological study design, with the Integrated Behavioural Model used as a framework for analysis and interpretation.

Woldia, North Wollo, Ethiopia, 13–30 February 2024.

Twenty female sex workers and 18 key informants in Woldia participated in in-depth interviews, key informant interviews and focus group discussions.

The advantages related to OraQuick HIVST include its privacy, ease of use, reduced waiting time, lowered transportation costs, usability for immobile individuals, application in screening for index case testing programmes, providing confidence and reliability and the elimination of the need for healthcare providers during testing. Perceived possible challenges for the uptake of OraQuick HIVST included kit shortage, absence of policies or guidelines for HIVST, lack of post-test counselling and immediate treatment for positive individuals, potential psychological trauma such as suicidal ideation or attempts, lack of linkage to care for those with reactive results, inaccurate reporting of positive results or result concealment and doubts about reliability before education. Strategies perceived for enhancing the uptake of OraQuick HIVST included making the HIVST kit accessible to higher education communities, addressing HIVST-related doubts by including phone or email contact information, advocating and creating awareness about OraQuick HIVST and ensuring the availability of kits in easily accessible locations.

The study findings highlight many positive opportunities related to the uptake of OraQuick HIVST. Policymakers should prioritise addressing the challenges identified and implementing the proposed strategies to enhance the uptake of OraQuick HIVST, potentially leading to improved HIV testing rates and outcomes.

Primary care electronic health records provide a rich source of information for inequalities research. However, the reliability and validity of the research derived from these records depend on the completeness and resolution of the codelists (ie, collections of medical terms/codes) used to identify populations of interest. The aim of this project was to develop comprehensive codelists for identifying people from ethnic minority groups, people with learning disabilities (LDs), people with severe mental illness (SMI) and people who are transgender.

We followed a three-stage process to define and extract relevant codelists. First, groups of interest were defined a priori. Next, relevant clinical codes, relating to the groups, were identified by searching Clinical Practice Research Datalink (CPRD) publications, codelist repositories and the CPRD Code Browser. Relevant codelists were extracted and merged according to group, and duplicates were removed. Finally, the remaining codes were reviewed by two general practitioners (GPs).

The curated codelists were compared using a representative sample in the UK. The frequencies of individuals identified using the curated codelists were assessed and compared with widely used alternative codelists.

Comprehensiveness was assessed in a representative CPRD population of 10 966 759 people.

After removal of duplicates and GP review, codelists were finalised with 325 unique codes for ethnicity, 558 for LD, 499 for SMI and 38 for transgender. Compared with comparator codelists, an additional 48 017 (76.6%), 52 953 (68.9%) and 508 (36.9%) people with LD, SMI or transgender code were identified. The proportions identified for ethnicity, meanwhile, were consistent with expectations for the UK (eg, 6.50% Asian, 2.66% black and 1.44% mixed).

The curated codelists are more sensitive than those widely used in practice and research. Discrepancies between national estimates and primary care records suggest potential record/retention issues. Resolving these requires further investigation and could lead to improved data quality for research.

We calculate positive predictive values (PPVs) of patients presenting with unexpected weight loss (UWL) being diagnosed with cancer within 6 months, using data from a population of Australian primary care patients to replicate results from a previous UK study.

A diagnostic accuracy study involving calculation of the PPV for any cancer using retrospective data from routinely collected electronic healthcare records. The index date is defined as the first recorded UWL presentation and the reference standard is cancer diagnosis within 6 months of the index date.

This study uses primary care data from the Patron primary care database, linked to hospital admissions data and the Victorian Cancer Registry. We include only patients who presented to their General Practitioners (GPs) at least once between 1 July 2007 and 1 February 2022.

Patients were included if they were at least 18 years of age at the index date, had no previous diagnosis of cancer or previous weight loss intervention, including being prescribed medications for weight loss. 13 306 patients out of a primary care population of 1 791 051 patients were identified that met the eligibility criteria.

When stratified by age, sex and smoking status, we found PPVs lower than those derived in a previous UK primary care study, though still above 3% for male non-smokers over 60, female smokers over 70 and all males over 70. Patients from ages 60–79 with at least one abnormal blood test result had PPVs consistently above 3%, while overall, patients with abnormal blood test results have PPVs of up to 35%.

We confirmed that many PPVs, while consistently below those derived in the UK study, are above clinically significant thresholds and increasing with age and the number of different abnormal blood test results.

Acute low back pain (LBP) is a prevalent condition with various non-surgical treatment options, yet no comprehensive network meta-analysis has systematically compared their relative efficacy for pain and disability. This study aims to fill that gap by synthesising available evidence on the efficacy of different types of non-surgical interventions for acute LBP, such as various medications, manual therapies and education-based therapies. Our coprimary objectives are to (1) compare each active treatment to an inert reference for measures of LBP and related disability and (2) rank the efficacy of treatments.

We will conduct a systematic search across multiple databases, including grey literature, to identify randomised controlled trials evaluating non-surgical treatments for acute LBP. Eligible studies must report on pain and/or disability outcomes in adults. The risk of bias will be assessed using the Risk of Bias tool, and the certainty of evidence will be graded using CINeMA (Confidence in Network Meta-Analysis). We will use a frequentist network meta-analysis to pool standardised mean differences in pain and disability, employing random-effects models to account for heterogeneity. A qualitative analysis will assess study characteristics and transitivity, while a quantitative analysis will evaluate efficacy and inconsistency. Results will be presented using network geometry, p-scores, forest plots, funnel plots, Egger’s test, Q-statistics and league tables to visualise both direct and indirect evidence and to identify potential biases.

This review protocol does not involve any primary research with human participants, animal subjects or medical record review. Consequently, this work did not require approval from an institutional review board or ethics committee. Results will be submitted to a peer-reviewed journal and presented at conference(s). De-identified data will be made available in a public repository.

International consensus guidelines support the initial administration of 30 mL/kg of intravenous fluids for haemodynamic resuscitation of newly diagnosed septic shock. Practice variation exists between the volume of fluids administered and timing of vasopressor commencement. The optimal approach in patients with septic shock is uncertain.

Australasian Resuscitation In Sepsis Evaluation: FLUid or vasopressors In emergency Department Sepsis is a 1000-participant multicentre, randomised, open-label, parallel group clinical trial conducted in patients with septic shock presenting to the emergency department in participating sites in Australia, New Zealand and Ireland. Participants are randomised (1:1) to either restricted fluids and early vasopressors or a larger initial intravenous fluid volume and later vasopressors. The primary outcome is days alive and out of hospital at day 90 postrandomisation. Secondary outcomes are all-cause mortality at day 90, time from randomisation until death (to day 90), days alive and at home at day 90 and ventilator-free, vasopressor-free and renal replacement-free days to day 28 postrandomisation and death or disability at 6-month and 12-month postrandomisation. Health-related quality of life will be assessed at day 180 and 12 months following randomisation.

The study was approved by Northern Sydney Local Health District Human Research Ethics Committee (HREC2020/ETH02874) on 21 January 2021. Patients will be enrolled under a waiver of prior consent. The patient or next-of-kin (or equivalent according to local jurisdiction) is approached at the first available opportunity and given a trial information sheet. According to local approvals, the patient or next-of-kin chooses to either continue in the trial or opt-out/decline continued participation. Results will be disseminated in peer-reviewed journals and presented at academic conferences.

Acknowledging equality, diversity and inclusion (EDI) in research is not only a moral imperative but also an important step in avoiding bias and ensuring generalisability of results. This protocol describes the development of STAndards for ReporTing EDI (START-EDI) in research, which will provide a set of minimum standards to help researchers improve their consistency, completeness and transparency in EDI reporting. We anticipate that these guidelines will benefit authors, reviewers, editors, funding organisations, healthcare providers, patients and the public.

To create START-EDI reporting guidelines, the following five stages are proposed: (i) establish a diverse, multidisciplinary Steering Committee that will lead and coordinate guideline development; (ii) a systematic review to identify the essential principles and methodological approaches for EDI to generate preliminary checklist items; (iii) conduct an international Delphi process to reach a consensus on the checklist items; (iv) finalise the reporting guidelines and create a separate explanation and elaboration document; and (v) broad dissemination and implementation of START-EDI guidelines. We will work with patient and public involvement representatives and under-served groups in research throughout the project stages.

The study has received ethical approval from the Imperial College London Research Ethics Committee (study ID: 7592283). The reporting guidelines will be published in open access peer-reviewed publications and presented in international conferences, and disseminated through community networks and forums.

The project is pre-registered within the Open Science Framework (https://osf.io/8udbq/) and the Enhancing the Quality and Transparency of Health Research Network.

The prevalence of women with primary dysmenorrhoea is high and negatively impacts physical and mental health. The intense cyclic episodes of pain generate central nervous system dysfunctional processing. In this sense, strategies focused on the central nervous system are important to re-establish normal functioning. Home-based self-administered transcranial direct current stimulation (tDCS) emerges as a strategy to modulate dysfunctional brain areas and improve the symptoms. This protocol aims to evaluate the effects of home-based self-administered tDCS for pain, premenstrual symptoms, physical performance, quality of life, electroencephalography and patient global impression in women affected by primary dysmenorrhoea.

This is a single-centre, parallel, randomised, double-blinded clinical trial protocol. 40 women affected by primary dysmenorrhoea will be randomised into two groups (active-tDCS or sham-tDCS). Then, 20 consecutive sessions of home-based self-administered tDCS will be performed. The assessments will occur at five time points: baseline, after the 20th sessions, at the first, second and third cycles after tDCS interventions (follow-ups). Primary outcome will be pain according to visual analogue scale. Quality of life, premenstrual symptoms screening, depression, anxiety, physical performance, electroencephalography and participants’ satisfaction will be the secondary outcomes. A mixed analysis of variance will calculate the effect of stimulation.

The study was approved by the ethics committee of the Federal University of Rio Grande do Norte (No. 6.037.756) and registered in the Brazilian Clinical Trials Registry (n° RBR-747k8vb). Participants may withdraw at any time without penalty. Free support will be available from the lead researcher if needed. All procedures will follow Good Clinical Practice and international ethical standards.
