BackgroundBacille Calmette-Guerin (BCG) is the most commonly-used vaccination globally, but multi-country cost-effectiveness analyses are outdated and have not considered sequelae in tuberculosis survivors. A rationale is lacking to guide the size of safety stocks. MethodsFor the 110 countries using universal neonatal BCG vaccination, we used a decision tree model to compare the costs and health benefits of status-quo BCG vaccination for children aged 0-4 years in 2023 to a counterfactual where...

BackgroundThere is growing evidence that individuals with different skin phototypes require tailored approaches to achieve optimal photoprotection. Individuals with darker skin phototypes are more prone to UVA1- and visible light-induced pigmentation, whereas lighter phototypes are more susceptible to shorter wavelengths such as UVB and UVA2. Thus, skin phototype is an important determinant of sunscreen efficacy. In the present study we have asked if ethnicity - independent of phototype - is ano...

BackgroundLinked administrative data covering whole populations are fundamental resources for longitudinal studies of children with rare conditions (cases) and unaffected peers (comparators). Data minimisation regulations sometimes limit the number of comparators per case (sampled comparators, SC), with unknown impact on study findings. MethodsUsing Monte Carlo draws, we simulated 100 000 children with and without an exemplar condition, congenital hypothyroidism (CHT), with covariates (sex and ...

Background and ObjectivesAnnual tuberculosis (TB) screening is recommended for all children and adolescents in the United States, but gaps remain in the diagnosis and treatment of latent TB infection (LTBI). We utilized the electronic health record (EHR) to examine the pediatric LTBI care cascade and assessed if an EHR note template could increase risk factor screening. MethodsWe extracted EHR data from well-child and -adolescent visits at a federally qualified health center in Northern Califor...

Understanding the burden of pertussis and pertussis-related mortality is important in enabling better understanding of population vulnerability and supporting vaccination programme planning. However, changes in laboratory practice can have important implications for public health surveillance. This study considers the impact of increasing use of multiplex panel testing for respiratory pathogens on ascertainment of pertussis-related deaths, drawing on multiple surveillance data sources from Engla...

ObjectiveTo evaluate the criterion-related and discriminant validity, test-retest reliability and minimal detectable difference of The Index of ME Symptoms (TIMES) in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) MethodsPeople with ME/CFS in the UK completed the TIMES online (n=1055). Rasch-transformed interval data and parametric statistics were used: Pearson correlations (with the ME severity scale); analysis of variance; intra-class correlations (ICC) and standard error of meas...

ObjectiveThe main objective was to estimate the potential public health impact and cost-effectiveness of an annual dose of mRNA-1273 (2025/2026 formula) in the United States (US) for the 2025-2026 season compared with no vaccination in the mRNA-1273 licensed population (6 months-64 years with underlying medical conditions and all [≥]65 years). mRNA-1273 was also compared to BNT162b2 in high-risk adults ages 18-64 years and all [≥]65 years. MethodsAnalyses were conducted using a previously...

ObjectiveTo develop and psychometrically evaluate an assessment of symptoms in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) MethodsAn initial symptom list was devised from the relevant literature with the patient and clinician advisory groups. An online survey with 85 symptom items in eight domains was completed by people with ME/CFS. Each item had two response structures (assessing symptom frequency and severity on five-point scales). Rasch analysis assessed each domain for unid...

BackgroundDuring the COVID-19 pandemic period, healthcare systems substantially reorganized their management of several diseases, including acute cardiovascular diseases (ACVD) such as heart failure, stroke, myocardial infarction, and pulmonary embolism. While previous studies have reported changes in hospitalization rates and clinical outcomes, the economic impact of the pandemic on healthcare expenditures for patients with ACVD remains poorly documented. This study aimed to quantify disruption...

The adoption of artificial intelligence in dermatology promises democratized access to healthcare, but model reliability depends on the quality and comprehensiveness of the data fueling these models. Despite rapid growth in publicly available dermatology images, the field lacks quantitative key performance indicators to measure whether new datasets expand clinical coverage or merely replicate what is already known. Here we present SkinMap, a multi-modal framework for the first comprehensive audi...

Backgroundfollowing a first cutaneous squamous cell carcinoma (CSCC), one-third of patients develop new primaries, escalating their risk of metastasis and poor outcomes. However, current follow-up strategies are not risk-stratified, representing a critical gap in patient management. Objectiveto develop and validate a prognostic model to quantify individualized absolute risk of a first metachronous CSCC after an index tumor, accurately accounting for the high competing risk of mortality in this ...

ObjectivesTo evaluate the efficacy and safety of sitafloxacin-containing regimens versus non-sitafloxacin therapy in patients with nontuberculous mycobacterial (NTM) pulmonary disease, focusing on sputum/BALF conversion rate, time of sputum/BALF culture conversion and radiographic improvement.
