A compelling aspect of both medicine and poetry is how each incites us to articulate our perceptions through specific applications of expressive language. In medicine, words are firmly grounded upon what we directly observe; assumptions are discouraged, for concern that unconscious biases might lead to erroneous conclusions. In poetry, on the other hand, what we see is often just a touchstone for what we can infer, our imaginations unbounded by an idiom that senses as much as it describes. These two modes of comprehending are instructively contrasted in “The Morning After the Election.” We are at first dropped into a narrative about a father and a daughter, reckoning momentarily that the daughter “who had once been his son” and now living far away has been rejected by her family—until the poetically appreciated detail of “the mustache obscuring his lip quivered” as he describes her new imperilment leads us to a deeper inference instead that he must accept and love her. Additional surprising implications that further test objectivity follow, from the reference to another “perfect” son whose death during childbirth ended the patient’s marriage, which underscores how the speaker may have wrongly construed that the transgender child caused familial strife, to the oversimplified and also partly true (yet in retrospect not entirely so, and thus all the more poignant) reason for the patient’s clinic visit as solely “because his blood pressure is high.” Poetry, by transcending the ostensible and harkening to the intuited, allows us to more fully grasp the complexities of our patients’ experiences.

Blood-Based Colorectal Cancer Screening
Despite a significant decline in colorectal cancer (CRC) incidence and mortality over the past several decades in the US, CRC remains the second leading cause of cancer deaths. Most of these deaths could be prevented if the 42% of Americans aged 45 to 75 years who are not up to date with screening would participate. There is strong evidence supporting screening with lower intestinal endoscopy (ie, colonoscopy or flexible sigmoidoscopy) or repeated rounds of occult blood–based stool screening tests. These screening tests are effective in detecting cancer at early, curable stages as well as preventing cancer through detection and removal of advanced precancerous lesions, including adenomas and serrated colorectal lesions. Despite public awareness campaigns, organized screening (eg, programmatic mailed stool-based tests), and patient decision aids and navigation, participation is suboptimal, and closing the screening gap remains elusive. This gap may result from reluctance to complete screening due to inconvenience, discomfort, embarrassment, aversion to handling stool, or fear of complications. The ideal CRC screening test would be noninvasive and acceptable to those being screened, be highly sensitive for both early cancer and advanced precancerous lesions, have excellent specificity, and be widely accessible. All of the currently available CRC screening test options fall short of this ideal in at least 1 way, limiting their effectiveness. Thus, there is an ongoing search for more agreeable screening test options.
Assessing symptom improvement in patients with postural orthostatic tachycardia syndrome (POTS) following a 16-week structured exercise programme: a protocol for a randomised cross-over trial in a clinical outpatient setting
Introduction
Exercise training is recommended as a complementary treatment in postural orthostatic tachycardia syndrome (POTS) according to international guidelines. However, less is known regarding how exercise training could successfully be implemented in clinical practice in patients with POTS. Thus, in the current study, we aim to assess the effect of a 16-week tailored exercise training programme in POTS.
Methods and analysis
A total of 200 patients diagnosed with POTS will be recruited. The study will be conducted as a randomised cross-over study. POTS symptoms will be evaluated using the Malmö POTS Symptom Score, Orthostatic Hypotension Questionnaire and 36-item Short Form Health Survey. Haemodynamic parameters will be evaluated by orthostatic tests and maximum working capacity evaluated by bicycle exercise test. Symptoms, haemodynamic parameters and exercise capacity will be assessed before and after a 16-week training programme.
Ethics and dissemination
The study was approved by the Swedish ethical review authority (2022-03186-01) and all procedures will be performed in accordance with the Helsinki Declaration. Results will be made available to patients with POTS, healthcare professionals, the funders and other researchers in publicly available (open access) medical journals.

Risk of myocardial infarction and stroke following microbiologically confirmed urinary tract infection: a self-controlled case series study using linked electronic health data
Objectives
The inflammatory response from acute infection may trigger cardiovascular events. We aimed to estimate associations between microbiologically confirmed urinary tract infections (UTIs) and first acute myocardial infarction (MI) and stroke.
Design
We used a self-controlled case series, with risk periods 1–7, 8–14, 15–28 and 29–90 days after UTI. Included individuals experienced the outcome and exposure of interest and acted as their own controls.
Setting
We used individually linked general practice, hospital admission and microbiology data for the population of Wales held by the Secure Anonymised Information Linkage databank.
Participants
Included individuals were Welsh residents aged over 30 years with a record of a hospital admission for MI or stroke (outcomes) and evidence of a microbiologically confirmed UTI (exposure) during the study period of 1 January 2010 to 31 December 2020.
Main outcome measures
The primary outcome was acute MI or stroke identified using the International Classification of Disease V.10 codes from inpatient diagnoses recorded in the Patient Episode Database for Wales. We used Poisson regression to estimate incidence rate ratios (IRRs) and 95% CIs for MI and stroke during predefined risk periods, compared with baseline periods.
Results
During the study period, 51 660 individuals had a hospital admission for MI, of whom 2320 (4.5%) had 3900 microbiologically confirmed UTIs, and 58 150 had a hospital admission for stroke, of whom 2840 (4.9%) had 4600 microbiologically confirmed UTIs. There were 120 MIs during risk periods and 2190 during baseline periods, with an increased risk of MI for 1–7 days following UTI (IRR 2.49, 95% CI (1.65 to 3.77)). There were 200 strokes during risk periods and 2640 during baseline periods, with an increased risk of stroke for 1–7 days following UTI (IRR 2.34, 95% CI (1.61 to 3.40)).
Conclusions
UTI may be a trigger for MI or stroke. Further work is needed to understand mechanisms and test interventions to reduce the risk of cardiovascular events among people with UTIs in primary care.

Evaluating DOAC dipstick testing in the management of acute stroke: protocol for a multicentre, prospective, observational registry study
Introduction
Direct oral anticoagulants (DOACs) are preferred over vitamin K antagonists for stroke prophylaxis in non-valvular atrial fibrillation. Yet, DOAC use is regarded as a contraindication for intravenous thrombolysis in acute ischaemic stroke. The stratification of patients into ‘on-therapy’ and ‘off-therapy’ categories based on their plasma DOAC concentrations is particularly crucial in the acute phase of stroke when decisions for thrombolysis or anticoagulation reversal are time-sensitive. The novel point-of-care DOAC dipstick assay (DOASENSE) rapidly assesses urine for clinically significant DOAC levels, potentially broadening eligibility for thrombolysis or targeted reversal therapy. This multicentre prospective observational registry study aims to evaluate the accuracy and clinical utility of DOAC dipstick testing compared with plasma DOAC assays in acute stroke management across regional Australian hospitals.
Methods and analysis
This multicentre, prospective, observational study will enrol participants presenting to hospitals across Victoria and Tasmania with acute ischaemic stroke or intracerebral haemorrhage with DOAC ingestion within 48 hours of presentation. Plasma DOAC concentrations measured by chromogenic assays will be compared with rapid urine dipstick results from DOASENSE testing. There is a target sample size of 146 participants. The primary outcomes are as follows: (1) proportion of ischaemic stroke participants with off-therapy plasma DOAC levels and (2) eligibility for reperfusion therapy based on DOASENSE and plasma DOAC concentrations. Secondary outcomes are follows: (1) ischaemic stroke aetiology for participants with on-therapy vs off-therapy DOAC levels; (2) proportion of participants meeting criteria for pharmacological DOAC reversal based on DOASENSE outcomes; (3) incidence of false-negative and false positive DOASENSE results in clinically significant DOAC plasma concentrations at a threshold of ≥30 ng/mL and (4) an exploratory analysis of any false negative DOASENSE assays to identify potential contributing factors.
Ethics and dissemination
Ethics approval has been granted by the Eastern Health Human Research Ethics Committee (reference number: 99628). Dissemination of findings will occur through peer-reviewed publications and academic conferences.
Development and validation of an interpretable machine learning model for predicting Philadelphia chromosome-positive acute lymphoblastic leukaemia using clinical and laboratory parameters: a single-centre retrospective study
Objective
To develop and validate a prediction model of Philadelphia chromosome-positive acute lymphoblastic leukaemia (Ph+ALL).
Design
A single-centre retrospective study.
Participants
This study analysed 471 newly diagnosed patients with ALL at the Second Affiliated Hospital of Army Medical University from January 2014 to December 2023.
Methods
Clinical and laboratory parameters were collected, and the important characteristic parameters were selected using BorutaShap. Multiple machine learning (ML) models were constructed and optimised by using the active learning (AL) algorithm. Performance was evaluated using the area under the curve (AUC), comprehensive indicators and decision curve analysis. The interpretability of the model was evaluated by using SHapley Additive Interpretation (SHAP), and external validation was conducted on an independent test cohort.
Results
10 parameters were selected to construct multiple ML models. The CatBoost model integrated with an AL algorithm (CatBoost-AL) was found to be the most effective model for predicting Ph+ALL within the validation data set. This model achieved an AUC of 0.797 (95% CI 0.710 to 0.884), along with sensitivity, specificity and F1 score of 0.667, 0.864 and 0.777, respectively. The prediction performance of CatBoost-AL was further validated with an external testing set, where it maintained a strong AUC of 0.794 (95% CI 0.707 to 0.881). Using SHAP for global interpretability analysis, age, monocyte count, -glutamyl transferase, neutrophil count and alanine aminotransferase were identified as crucial parameters that significantly influence the diagnostic accuracy of CatBoost-AL.
Conclusion
An interpretable ML model and online prediction tool were developed to determine whether newly diagnosed patients with ALL are Ph+ALL. The key parameters identified by the optimal model provided a further understanding of Ph+ALL characteristics and were valuable for accurate diagnosis and treatment of Ph+ALL.
Multicomponent intervention for controlling hypertension in the adult rural population of Pakistan: a protocol for a hybrid type III implementation-effectiveness cluster randomised controlled trial
Introduction
Though prior trials have shown the effectiveness of community-based hypertension detection and care delivery models, their adoption and translation to practice has been slow. In this study, we will develop and test strategies for the implementation and scale-up of a proven multicomponent hypertension intervention (MCHI) in Pakistan that comprises health education, blood pressure (BP) monitoring and referrals by lady health workers (LHWs) and hypertension management by physicians in primary care settings.
Methods and analysis
In this 24-month hybrid type III implementation-effectiveness cluster-randomised controlled trial, we will recruit 3000 adult hypertensive patients from two rural districts of Pakistan. We will engage public health sector managers, physicians and LHWs and use the Consolidated Framework for Implementation Research to identify barriers and facilitators to the implementation of an already proven-to-be-effective MCHI. Using Expert Recommendations for Implementing Change and the modified Delphi technique, a set of implementation strategies addressing barriers will be identified. The strategies will be categorised as level 1 (requiring a change in processes), level 2 (requiring a change in infrastructure) and level 3 (financial restructuring). Basic health units and 250–300 households from their catchment will be considered as clusters. Clusters will be randomised in a ratio of 1:1 to intervention and control. While MCHI will be offered in both trial arms (intervention and control), the aforementioned implementation strategies will be randomised to the intervention arm only, starting with level 1 and moving to levels 2 and 3 as needed. Baseline and 6-monthly follow-up surveys, each of 6 months duration, will be conducted to collect data from the recruited participants on sociodemographics, cardiovascular disease (CVD) risk factors, CVD-related expenses and quality of life. The primary outcome will be the mean difference in BP-lowering medications per participant between the intervention and control arms. The primary outcome will be analysed using a linear mixed model with fixed effects for baseline value of the outcome. Additional outcomes include implementation outcomes: proportion of LHWs conducting health education, BP screening and monitoring, facility referrals and proportion of physicians diagnosing and treating hypertensive patients; effectiveness outcomes: proportion of participants with controlled BP and improved EQ-5D-5L score.
Ethics and dissemination
Ethical approval has been obtained from the Ethics Review Committee of Aga Khan University Pakistan (ERC # 2023-9084-26739). Findings will be reported to: (1) study participants; (2) funding body and institutes collaborating and supporting the study; (3) provincial and district health departments to inform policy; (4) presented at local, national and international conferences and (5) disseminated by peer-review publications

Prevalence of low-level viremia in the treatment of chronic hepatitis B in China: a systematic review and meta-analysis
Objectives
Low-level viremia (LLV) is a risk factor affecting the prognosis of patients with chronic hepatitis B (CHB). The objective of this study was to systematically assess the prevalence of LLV, thereby providing robust evidence-based medical insights into effective clinical interventions and preventative measures against LLV.
Design
Systematic review and meta-analysis.
Data sources
A comprehensive literature search was conducted across various databases, including China National Knowledge Infrastructure, Wanfang Data (Wanfang), China Science And Technology Journal Database (VIP-CSTJ), China Biology Medicine disc (CBMdisc), PubMed, Embase, Web of Science and the Cochrane Library, spanning from the inception of these databases up to 5 January 2024.
Eligibility criteria
The research type included either a cross-sectional study or a cohort study focusing on the Chinese population, with the outcome being LLV. The languages were limited to both Chinese and English. Studies with any of the following were excluded: subjects with other comorbidities, original articles inaccessible or data unavailable, and duplicate publications.
Data extraction and synthesis
Literature management used EndNote X9.1, and an information extraction table was created using Microsoft Excel to record research information, including first author, year of publication and study type. The prevalence of LLV was assessed via meta-analysis. Meta-analyses were conducted in RStudio using the ‘metaprop ()’ function. Subgroup analysis and sensitivity analysis were used to identify sources of heterogeneity, and funnel plots and AS-Thompson tests were employed to evaluate publication bias.
Results
18 studies, encompassing a total sample of 9773 patients, were included in the analysis. Of these, 3336 patients were identified with LLV. The meta-analysis revealed that the prevalence of LLV among treated CHB patients stands at 33.6% (95% CI 30.2 to 37.0). The antigen status, antiviral treatment regimen (type of drugs and nucleos(t)ide analogues (NAs)), treatment duration, medication adherence and baseline hepatitis B virus DNA levels all affected the prevalence of LLV. Sensitivity analysis further corroborated the stability of these meta-analysis findings. The funnel plot and AS-Thompson test indicated no significant publication bias (t = –0.01, p=0.995).
Conclusions
The prevalence of LLV among CHB patients was established at 33.7% (95% CI 29.8% to 37.6%). Thus, it is imperative for clinical decision-makers to consider the various influencing factors of LLV when formulating treatment plans in order to mitigate any potential adverse outcomes.

Effects of potassium-enriched salt substitutes on blood pressure in Iranian hypertensive patients: the protocol for a randomised, double-blind controlled trial
Introduction
Potassium-enriched salt substitutes have favourable effects on blood pressure, but it has not been tested in Iran. The present protocol is a double-blinded, randomised-controlled trial designed to investigate the effects of potassium-enriched salt substitutes on blood pressure in Iranian hypertensive patients.
Methods and analysis
The primary objectives are to determine the effects on systolic and diastolic blood pressure at 3 months and 6 months. The secondary objectives are to assess the effects on serum levels of potassium, sodium, urea and creatinine; the urinary ratio of sodium to potassium; participants’ attitudes toward the use of salt or salt substitutes; the recurrence of hypertensive crisis; and the occurrence and/or reoccurrence of strokes, transient ischaemic attack and cardiovascular accidents. Eligible individuals will receive the usual salt (100% sodium chloride) in the control group or salt substitute (70% sodium chloride and 30% potassium chloride) in the intervention group. A total of 500 hypertensive participants aged 40–65 years will be recruited and randomised to intervention or control groups. Potassium-enriched salt substitution in Iran will be considered to improve CVD complications and prevent deaths. Continuous and categorical baseline characteristics will be tested using the independent t-test and 2 test. The effect of the intervention on primary and secondary outcomes will be assessed using the intention-to-treat method and two-way mixed ANOVA models.
Ethics and dissemination
This study has been approved by Alborz University of Medical Sciences (0-0-103-6369) and has received ethics approval (IR.ABZUMS.REC.1402.293). We will publish our study findings for peer-reviewed publications, conference presentations and digital stories.

Development and validation of critical appraisal tool for individual participant data meta-analysis: protocol for a modified e-Delphi study
Introduction
Individual participant data meta-analysis (IPD-MA) is regarded as the gold standard for evidence synthesis. However, diverse recommendations and guidance on its conduct exist, and there is no consensus-based tool for the critical appraisal of a completed IPD-MA. We aim to close this gap by systematically identifying quality items and developing and validating a critical appraisal checklist for IPD-MA.
Methods and analysis
This study will comprise three phases, as follows:
Phase 1: a systematic methodology review to identify potential checklist domains and items; this will be conducted according to the Cochrane methods for systematic reviews and reported following the Preferred Reporting Items for Systematic Reviews and Meta-analysis 2020 guidance. We will include studies that address methodological guides and essential statistical requirements for IPD-MA. We will use the proposed items to prepare a preliminary checklist for the e-Delphi study.
Phase 2: at least two rounds of an e-Delphi survey will be conducted among panels with expertise in IPD-MA research, consensus development, healthcare providers, journal editors, healthcare policymakers, patients and public partners from diverse geographic locations with experience in IPD-MA. Participants will use Qualtrics software to rate items on a 5-point Likert scale. The Wilcoxon matched signed rank test will estimate response stability across rounds. Consensus on including an item will be achieved if ≥75% of the panel rates the item as ‘strongly agree’ or ‘agree’ and items will be excluded if ≥75% rates it as ‘strongly disagree’ or ‘disagree’. A convenience sample of 10 reviewers with experience in conducting an IPD-MA will pilot-test the checklist to provide practical feedback that will be used to refine the checklist.
Phase 3: critical appraisal checklist validation: to improve confidence in the tool’s uptake, a subset of the e-Delphi participants and graduate students of epidemiology and biostatistics will conduct content validity and reliability testing, respectively, per the Consensus-based Standards for the Selection of Health Measurement Instruments.
Ethics and dissemination
Ethics approval has been obtained from the Western University Health Science Research Ethics Board in Canada. The validated checklist will be published in a peer-reviewed open-access journal and shared across the networks of this study’s steering committee, Cochrane IPD-MA group and the institutions’ social media platforms.
