Background
Despite global improvements in antiretroviral therapy (ART) access for children and adolescents living with HIV (CALHIV), a significant proportion continue to experience unsuppressed viral load (USVL). Limited studies focus on the factors contributing to USVL among CALHIV in the Democratic Republic of the Congo (DRC), especially in the context of evolving treatment landscapes. Understanding these determinants is crucial for enhancing ART outcomes.

Objective
This study aimed to determine the prevalence of USVL and identify factors associated with USVL among CALHIV receiving ART in Lubumbashi, DRC.

Design
A multicentre retrospective cross-sectional study was conducted. Data were gathered using an observational checklist based on assessing patient file data and entered into Microsoft Excel. Analysis was performed using STATA V.16. Variables with a p value of 0.20 from the bivariable analysis were included in a multivariable logistic regression model, and significant variables (p

Stroke, Ahead of Print. BACKGROUND:Left atrial (LA) diverticula are focal outpouchings of the LA wall and may increase ischemic stroke risk. We studied recurrent ischemic stroke in patients with acute ischemic stroke and LA diverticula detected on cardiac computed tomography.METHODS:We used data from a prospective cohort study of patients with acute ischemic stroke undergoing cardiac computed tomography acquired during the acute stroke imaging protocol. Cardiac radiologists systematically assessed the presence and characteristics of LA diverticula, defined as LA wall outpouchings with a length/ostium width ratio >0.5 and length ≥3 mm. We compared recurrent ischemic stroke and functional outcome (modified Rankin Scale) after 2 years between patients with and without LA diverticula, adjusting for age, history of atrial fibrillation and ischemic stroke, and anticoagulation use.RESULTS:Of 447 included patients (median age 72 [interquartile range (IQR), 62–81], 59% male), 126 (28%) had LA diverticula: median length 6 mm (IQR, 4–8), width 5 mm (IQR, 4–7), and volume 113 mm3(IQR, 52–254). There was no statistically significant difference in age (median 70 [IQR, 58–79] versus 73 [IQR, 63–81];P=0.06), sex (64% versus 57% male;P=0.28), history of ischemic stroke (21% versus 17%;P=0.48), atrial fibrillation (11% versus 19%;P=0.09), or baseline National Institutes of Health Stroke Scale score (median 5 [IQR, 2–14] versus 5 [IQR, 3–14];P=0.54) between patients with and without LA diverticula, respectively. Recurrent ischemic stroke was more common in patients with LA diverticula (18/124 [15%] versus 24/314 [8%], adjusted hazard ratio, 2.01 [95% CI, 1.08–3.77]), and recurrence risk increased with diverticulum volume (adjusted hazard ratio, 1.02 [95% CI, 1.01–1.03] per 10 mm3). Functional outcome was better in patients with diverticula (median modified Rankin Scale score of 2 [IQR, 1–3] versus 3 [IQR, 1–6], adjusted common odds ratio, 0.62, [95% CI, 0.42–0.92]).CONCLUSIONS:LA diverticula are a common finding on cardiac computed tomography in patients with acute ischemic stroke, and the risk of recurrent ischemic stroke was increased in these patients, particularly in those with larger diverticula. Atrial diverticula may be a risk factor for recurrent ischemic stroke.REGISTRATION:URL:https://www.onderzoekmetmensen.nl/nl/trial/50352; Unique identifier: NL6413901818.

Circulation, Volume 152, Issue 1, Page 79-80, July 8, 2025.

Objectives
To study the prevalence of and interplay between common neuropsychiatric sequelae 3–4 years after onset of first-ever stroke—specifically post-stroke fatigue (PSF), post-stroke depression (PSD) and post-stroke cognitive impairment (PSCI).

Design
Population-based cohort study.

Setting
Catchment area of a Swedish University Hospital.

Participants
We recruited individuals with first-ever ischaemic stroke or intracerebral haemorrhage in the initial cohort; 151 of these died prior to follow-up and 47 (12%) were lost to detailed follow-up. We followed up 202 individuals with median age: 72 (IQR 65–79), 40% female, either in clinic, via home visits or via telephone.

Primary and secondary outcome measures
Primary outcome measures included PSF (Fatigue Assessment Scale), PSD (Patient Health Questionnaire-9) and PSCI (Montreal Cognitive Assessment). Secondary outcome measures included dependency in activities of daily living (ADL; Barthel Index), health-related quality of life (HRQoL; Short-Form Questionnaire-36, EuroQoL-5D and Stroke Impact Scale) and stroke severity (National Institutes of Health Stroke Scale (NIHSS)).

Results
Significant PSF was present in 46/195 (24%), PSD in 21/191 (11%), and PSCI in 93/173 (54%) respondents. Among 169 participants with available data for all three domains, 100 (59%) had impairment in at least one domain. Participants with PSCI were older than those without (median: 75 vs 67 years; p

Objective
To examine the association between behavioural risk factors and their physiological sequelae among adults aged 40 and above in Bo District, Sierra Leone.

Design
Cross-sectional study.

Setting
Household survey in Bo District, Sierra Leone.

Participants
The study included 1978 randomly sampled adults aged 40 and above (44.4% male and 55.6% female). The majority of participants were aged 40–49 years (34.5%). Data were collected using a household survey based on the validated WHO STEPs questionnaire.

Methods
Multivariable logistic regression analysis was performed to determine associations between behavioural risk factors (diet, physical activity and salt intake) and the presence of hypertension, diabetes and/or obesity, adjusting for sociodemographic variables.

Primary outcome measure
The primary outcomes were the presence of hypertension, diabetes or overweight/obesity. Hypertension was defined as systolic blood pressure of ≥140 mm Hg and/or diastolic blood pressure of ≥90 (measured); diabetes as fasting glucose of ≥7.0 mmol/L, random plasma glucose level of ≥11.1 mmol/L or the use of antidiabetic medications (self-reported) and overweight/obesity as having a body mass index of ≥25 kg/m² (measured).

Results
At least one physiological risk factor for cardiovascular diseases, that is, hypertension, obesity or diabetes, was present in 43.5% of participants. Hypertension was associated with urban living (OR=1.46, 95% CI (1.41 to 1.51)), older age (OR for 80+=3.98, 95% CI (3.70 to 4.28)), insufficient fruit and vegetable intake (OR=1.52, 95% CI (1.46 to 1.60)) and low physical activity (OR=1.35, 95% CI (1.27 to 1.43)). Diabetes was associated with urban residence (OR=1.84, 95% CI (1.66 to 2.05)), older age (OR for 70–79=3.82, 95% CI (3.28 to 4.45)), low fruit and vegetable consumption (OR=1.61, 95% CI (1.36 to 1.90)), high salt intake (OR=1.34, 95% CI (1.21 to 1.49)) and low physical activity (OR=1.47, 95% CI (1.26 to 1.71)). Obesity was associated with urban living (OR=1.66, 95% CI (1.59 to 1.72)), high salt intake from two or more sources (OR=1.21, 95% CI (1.17 to 1.25)) and low physical activity (OR=1.30, 95% CI (1.22 to 1.39)). Male sex (OR=0.37, 95% CI (0.36 to 0.38)) and older age (OR for 80+=0.39, 95% CI (0.35 to 0.43)) were protective factors.

Conclusions
In Bo District, nearly half of adults over 40 face hypertension, diabetes or obesity, especially urban dwellers, older age groups and those eating too few fruits and vegetables, consuming excess salt and getting little exercise. Public health efforts should focus on urban-targeted nutrition education, salt-reduction strategies, community exercise programmes and routine blood pressure and glucose screening, working with local leaders to ensure sustainable lifestyle changes and early disease detection.

Background
Angina, a major manifestation of ischaemic heart disease, affects 3–7% of adults and is a leading cause of cardiovascular morbidity. As an ambulatory care-sensitive condition, its outcomes can be improved through proactive outpatient management. However, the real-world impact of continuity of care (COC) and medication adherence, measured by the medication possession ratio (MPR)—on angina complications in South Korea remains poorly understood.

Objective
This study evaluated the effectiveness of COC and MPR in patients with angina using comprehensive national data and examined the outcomes at the hospital level.

Methods
This retrospective cohort study used data from the National Health Insurance Service of Korea between 2002 and 2019. We identified 11 127 patients aged >30 years newly diagnosed with angina, applying strict exclusion criteria to ensure cohort validity. COC was categorised as high (COC index=1.0) or low (

Objective
Amoxicillin-clavulanate is commonly used to prevent infections following snakebites despite the lack of clinical evidence. We aimed to demonstrate that clinically directed initiation of amoxicillin-clavulanate would be non-inferior to routine use in this setting.

Design
Open-label, randomised, non-inferiority trial with blinded adjudication of endpoints.

Setting
Emergency department of a teaching hospital in southern India.

Participants
Adults with local swelling following snakebites within 24 hours of bite.

Interventions
In the routine use strategy, intravenous followed by oral amoxicillin-clavulanate was administered for at least 5 days. In the clinically directed strategy, the antibiotic was only initiated for clinical failures.

Primary and secondary outcome measures
Primary outcomes were protocol-defined clinical failure and total antibiotic consumption. Non-inferiority margin was prespecified as 10%. Secondary outcomes were the length of hospital stay, total antivenom consumption, new-onset organ failure, bleeding requiring transfusion, death/need for surgical intervention and drug-related adverse events.

Results
The trial was prematurely stopped due to the COVID-19 situation after randomising 66 patients—34 to clinically directed initiation and 32 to routine use arms. Russell’s viper was the most common (21 (32%)) biting snake species identified; 52 (79%) patients had evidence of haemotoxic envenomation at baseline, and 24 (36%) patients developed AKI. There were 10 clinical failures—six in the clinically directed initiation arm and four in the routine use arm. The difference in clinical failure between the two arms was 5.2% (–12.0%–21.7%; p=0.291); the upper bound of the CI exceeded the prespecified non-inferiority margin. Total antibiotic consumption, expressed in DDDs, was significantly lower in the clinically directed initiation arm (0 (0–1) vs 5.31 (4.67–6.17); p

Objective
To quantify the carbon footprint of a sample of clinical trials for neurological disorders.

Design
Cross-sectional study.

Method
Two clinical trial registries were searched on 29 December 2022 for phase 2–4 randomised controlled trials led from and recruiting in the UK, enrolling people with any of the 15 neurological disorders with the highest global burden, that had started recruitment or been registered in the preceding 5 years. Eligible trials were invited to share data to estimate emissions in each of the 10 modules of the Low Carbon Clinical Trials footprinting guidance. The primary outcome measure was kg of carbon dioxide equivalent (CO2e).

Results
318 randomised controlled trials were found, nine were eligible and six shared data (three completed and three ongoing). The module with the highest estimated CO2e for each trial was the Clinical Trial Unit staff emissions (median 24 126 kg CO2e, IQR 10 395–78,867; range 45–79% of overall emissions of each trial); commuting accounted for >50% of CO2e in this module. The second and third highest modules were trial-specific participant assessments (median 11 497 kg CO2e, IQR 825–15,682) and trial supplies and equipment (median 1161 kg CO2e, IQR 226–6632). The total carbon footprint of these six trials involving 2248 participants at 239 sites was 2 63 215 kg CO2e.

Conclusions
Emissions by Clinical Trials Unit staff were the top modifiable carbon hotspot in six randomised controlled trials for people with neurological disorders, which had a total carbon footprint equivalent to 1364 passengers’ return aeroplane journeys between London and Edinburgh.

Circulation, Ahead of Print. BACKGROUND:The somaticJAK2V617Fsequence variation, a key driver of myeloproliferative neoplasms, has been associated with increased risk of aortic aneurysms. This study aimed to explore associations between theJAK2V617Fvariant allele frequency (VAF) and ascending, descending, and abdominal aortic aneurysms.METHODS:In the DANCAVAS I and II trials (Danish Cardiovascular Screening), 15 000 individuals underwent cardiovascular risk assessments including blood samples and noncontrast ECG-gated computed tomography scans. In this cross-sectional substudy, individuals with screening-detected aortic aneurysms (≥45 mm ascending, ≥35 mm descending, or ≥30 mm abdominal), random aneurysm-free male controls, and all women (only included during the DANCAVAS I pilot study) were tested for theJAK2V617Fsequence variation.RESULTS:A total of 8056 individuals (90.9% men, mean age 68±4 years) were tested for theJAK2V617Fsequence variation, which presented an overall prevalence of 7.1%. Ascending, descending, and abdominal aneurysm prevalences were 6.6%, 2.9%, and 6.8%, respectively. InJAK2V617F-negative participants (n=7486),JAK2V617F-positive participants with VAF

Stroke, Ahead of Print. BACKGROUND:This study aimed to investigate neurophysiological mechanisms underlying functional impairment and recovery after acute ischemic stroke using transcranial magnetic stimulation combined with electroencephalography, focusing on interhemispheric interactions and oscillatory dynamics.METHODS:This single-center case-control study (December 2022 to May 2024) included 19 ischemic stroke patients within 14 days of symptom onset (mean age, 47.95±12.41 years; 15 [79%] males) with 3-month poststroke follow-up. Sixteen age-matched healthy controls (53.56±9.83 years; 12 [80%] males) were included. Transcranial magnetic stimulation-evoked electroencephalography potentials, local mean field power during 25 ms and 35 ms (local mean field power25–35 ms), and power spectral density of the ipsilesional primary motor cortex (ilM1) were calculated when single-pulse transcranial magnetic stimulation was sequentially applied to the contralesional M1 (clM1) and ilM1. Spearman correlation analysis evaluated associations between transcranial magnetic stimulation combined with electroencephalography parameters and clinical outcomes: Fugl-Meyer assessment, Fugl-Meyer assessment-upper extremity subscale, National Institutes of Health Stroke Scale, and National Institutes of Health Stroke Scale changes from baseline to 3 months poststroke.RESULTS:Stroke patients exhibited simplified transcranial magnetic stimulation-evoked electroencephalography potential waveforms with reduced amplitudes compared with healthy controls. The contralesional resting motor threshold of stroke patients was significantly lower compared with healthy controls (t=−2.79;P=0.009). The contralesional resting motor threshold was positively associated with the local mean field power25–35 msof ilM1 with stimulation on ilM1 (r=0.482;P=0.018). The power and power spectral density of β oscillations were negatively associated with the Fugl-Meyer assessment (r=−0.557,P=0.014;r=−0.417,P=0.038, respectively) and Fugl-Meyer assessment-upper extremity (r=−0.503,P=0.014;r=−0.389,P=0.05, respectively), but the power of β oscillations was positively associated with changes in the National Institutes of Health Stroke Scale (r=0.507;P=0.027) with stimulation on clM1.CONCLUSIONS:Increased excitability of the clM1 is associated with decreased excitability of the ilM1. The inhibition of β oscillations in the ilM1 by the clM1 serves as a biomarker for poststroke functional impairment and recovery. Neuromodulation of the clM1 to enhance the β oscillations of ilM1 may be a promising treatment strategy.

Circulation, Ahead of Print. BACKGROUND:Proteomic signatures might improve disease prediction and enable targeted disease prevention and management. We explored whether a protein risk score derived from large-scale proteomics data improves risk prediction of atrial fibrillation (AF).METHODS:A total of 51 680 individuals with 1459 unique plasma protein measurements and without a history of AF were included from the UKB-PPP (UK Biobank Pharma Proteomics Project). A protein risk score was developed with lasso-penalized Cox regression from a random subset of 70% (36 176 individuals, 54.4% women, 2155 events) and was tested on the remaining 30% (15 504 individuals, 54.4% women, 910 events). The protein risk score was externally replicated with the ARIC study (Atherosclerosis Risk in Communities; 11 012 individuals, 54.8% women, 1260 events).RESULTS:The protein risk score formula developed from the UKB-PPP derivation set was composed of 165 unique plasma proteins, and 15 of them were associated with atrial remodeling. In the UKB-PPP test set, a 1-SD increase in protein risk score was associated with a hazard ratio of 2.20 (95% CI, 2.05–2.41) for incident AF. The C index for a model including CHARGE-AF (Cohorts for Heart and Aging Research in Genomic Epidemiology Atrial Fibrillation), NT-proBNP (N-terminal B-type natriuretic peptide), polygenic risk score, and protein risk score was 0.816 (95% CI, 0.802–0.829) compared with 0.771 (95% CI, 0.755–0.787) for a model including CHARGE-AF, NT-proBNP, and polygenic risk score (C-index change, 0.044 [95% CI, 0.039–0.055]). Protein risk score added to CHARGE-AF, NT-proBNP, and polygenic risk score resulted in a risk reclassification of 5.4% (95% CI, 2.9%–7.9%) with a 5-year risk threshold of 5%. In the decision curve, the predicted net benefit before and after the addition of protein risk score to a model including CHARGE-AF, NT-proBNP, and polygenic risk score was 3.8 and 5.4 per 1000 people, respectively, at a 5-year risk threshold of 5%. External replication of a protein risk score in the ARIC study showed consistent improvement in risk stratification of AF.CONCLUSIONS:Protein risk score derived from a single plasma sample improved risk prediction of AF. Further research using proteomic signatures in AF screening and prevention is needed.

Objectives
This article aimed to explore patients’ experiences of attending the emergency department (ED) for low back pain (LBP) and provides a theoretically informed analysis of the ED cultures perceived by patients to inform their experiences of care.

Design
Multisite, cross-sectional qualitative interview study.

Setting
Four NHS Emergency Departments located in the UK.

Participants
47 adults (aged 23–79 years) who, in the past 6 weeks, had attended the ED for LBP (all types and durations). Purposive sampling was used to gain variation in the recruiting sites, and participants’ LBP and demographic characteristics.

Interventions
Data were collected using individual, semistructured, telephone interviews (median 45 min duration) which were audio-recorded and transcribed verbatim. Analysis was informed using reflexive thematic analysis and ideal type analysis. Cycles of inductive and deductive analysis were undertaken, with Bourdieu’s concepts of field and habitus employed to help explain the findings.

Results
We present three contrasting cultures of ED care for LBP, comprising (1) emergency screening only, (2) ‘cynicism and neglect’ and (3) appropriate and kind care. Taking each culture (field) in turn, we explore important differences in the content and delivery of care. Drawing on Bourdieu’s concepts of field and habitus, we consider the social and institutional norms and misrepresentations likely to underpin the thoughts and behaviours of ED staff (their habitus), and why these tended to vary based on where and by whom the patient was managed in the ED.

Conclusions
Strategies to improve patients’ experience need to review the social and institutional norms that underpin staff habitus, the assumptions informing these norms and the voices that validate and reproduce them.

ISRCTN registration number
ISRCTN77522923.

Objective
Multi-cancer early detection (MCED) tests are novel technologies that detect cancer signals from a broad set of cancer types using a single blood sample. The objective of this study was to estimate the effect of screening with an MCED test at different intervals on cancer stage at diagnosis and mortality endpoints.

Design
The current model is based on a previously published state-transition model that estimated the outcomes of a screening programme using an MCED test when added to usual care for persons aged 50–79. Herein, we expand this analysis to model the time of cancer diagnosis and patient mortality with MCED screening undertaken using different screening schedules. Screening intervals between 6 months and 3 years, with emphasis on annual and biennial screening, were investigated for two sets of tumour growth rate scenarios: ‘fast (dwell time=2–4 years in stage I) and ‘fast aggressive’ (dwell time=1–2 years in stage I), with decreasing dwell times for successive stages.

Setting
Inputs for the model include (1) published MCED performance measures from a large case-control study by cancer type and stage at diagnosis and (2) Surveillance, Epidemiology and End Results (SEER) data describing stage-specific incidence and cancer-specific survival for persons aged 50–79 in the US for all cancer incidence.

Outcome measures
We used the following outcome measures: diagnostic yield, stage shift, and mortality.

Results
Annual screening under the fast tumour growth scenario was associated with more favourable diagnostic yield. There were 370 more cancer signals detected/year/100,000 people screened, 49% fewer late-stage diagnoses, and 21% fewer deaths within 5 years than usual care. Biennial screening had a similar, but less substantial, impact (292 more cancer signals detected/year/100,000 people screened; 39% fewer late-stage diagnoses, and 17% fewer deaths within 5 years than usual care). Annual screening prevented more deaths within 5 years than biennial screening for the fast tumour growth scenario. However, biennial screening had a higher positive predictive value (54% vs 43%); it was also more efficient per 100,000 tests in preventing deaths within 5 years (132 vs 84), but prevented fewer deaths per year.

Conclusion
Adding MCED test screening to usual care at any interval could improve patient outcomes. Annual MCED test screening provided more overall benefit than biennial screening. Modelling the sensitivity of outcomes to different MCED screening intervals can inform timescales for investigation in trials.

Idrocefalo normoteso, malattia curabile ma poco nota. Possibili fino a 35 miliardi di euro di risparmio in un anno per il Servizio sanitario nazionale

Objective
Due to the growing ageing population worldwide, more percutaneous coronary interventions (PCI) are being performed on elderly patients; however, current national data in Southeast Asian developing countries regarding patient characteristics, procedural details and PCI outcomes in elderly patients are insufficient.

Design
Observational study.

Setting
Nationwide registry from 39 primary PCI facilities across Thailand.

Participants
Between May 2018 and August 2019, the Thai PCI registry enrolled a total of 22 741 patients who underwent PCI. We examined patient characteristics, PCI technique and in-hospital outcomes in octogenarians (≥80 years) and non-octogenarians (18–79 years).

Results
There were 2099 patients (9.2%) over the age of 80. Octogenarians were at greater risk for atherosclerosis and calcified coronary lesions that required plaque modification and a higher risk of cardiogenic shock during presentation than non-octogenarians. The success rate of PCI in octogenarians was high (95.5%) and comparable to non-octogenarians (96%). The respective PCI failure rate in non-octogenarians and octogenarians was 4% and 4.5% (p=0.251). Octogenarians had a substantially greater incidence of periprocedural problems (5.6% vs 4.5%, p=0.011). PCI was linked with more than threefold increase in in-hospital mortality in octogenarians compared with non-octogenarians (7.67% vs 2.3%, p 0.001). Nonetheless, revascularisation with PCI in octogenarians increased the EQ-5D (European Quality of Life 5 Dimensions) score by 15.7 after PCI and before hospital discharge.

Conclusions
According to the Thai PCI registry, octogenarians had more complicated coronary anatomy, as well as higher procedural complications and mortality than non-octogenarians. Nonetheless, PCI in the octogenarian had a high success rate and potentially improved the patient’s quality of life.
