Objective: Despite effective treatment, gout is poorly managed. The aim of this study was to determine rates of serum urate (SU) testing and allopurinol dose adjustment in patients on allopurinol admitted to Christchurch based hospitals.

Methods: The hospital electronic prescribing and administration (ePA) system was used to identify patients on allopurinol during hospital admissions from March 2016-March 2023.

Background: Abnormal results in commonly used primary care blood tests could be early markers of cancer in patients presenting with non-specific abdominal symptoms.

Methods: Using linked data from the UK Clinical Practice Research Datalink (CPRD) and national cancer registry we compared blood test use and abnormal results from the 24-months pre-diagnosis in 10,575 cancer patients (any site), and 52,875 matched-controls aged ≥30 presenting, with abdominal pain or bloating to primary care.

Results: Cancer patients had two-fold increased odds of having a blood test (odds ratio(OR):1.

Purpose: Studies of healthcare encounters leading to cancer diagnosis have increased over recent years. While some studies examine healthcare utilization before the cancer registry date of diagnosis, relevant pre-diagnosis interactions are not always immediately prior to this date due to date abstraction guidelines. We evaluated agreement of a registry date with a claims-based index and examined Emergency Department (ED) involvement in cancer diagnosis as an example of possible pre-diagnostic healthcare misclassification that could arise from improper date choice.

Background: Dementia represents a growing healthcare challenge in the United States. The Care Ecosystem, an effective collaborative care model, bridges medical and social care needs for individuals with dementia. The purpose of this study was to describe how the Care Ecosystem has been disseminated and the lessons learned from this experience.

Background: Evidence on whether general practice rates of investigation in symptomatic patients using chest x-ray (CXR) affects outcomes is equivocal.

Aim: Determine if there is an association between rates of general practice (GP) requested CXR and lung cancer outcomes.

Design And Setting: Retrospective observational study (England) Methods: Cancer registry data for patients diagnosed with lung cancer 2014-2018 was linked to data on GP CXRs 2013-2017.

Background: Presenting to primary care with fatigue is associated with a wide range of conditions, including cancer, although their relative likelihood is unknown.

Aim: To quantify associations between new-onset fatigue presentation and subsequent diagnosis of various diseases, including cancer.

Design And Setting: A cohort study of patients presenting in English primary care with new-onset fatigue during 2007-2017 (the fatigue group) compared with patients who presented without fatigue (the non-fatigue group), using Clinical Practice Research Datalink data linked to hospital episodes and national cancer registration data.

Article Synopsis
  • The study examines discrepancies in cancer case status and diagnosis dates between cancer registry (CR) data and electronic health records (EHRs) for five types of cancer over a period from 1999 to 2018.
  • Among the findings, agreement in cancer diagnoses varied significantly between datasets, with combined CPRD-HES data confirming 84% to 92% of diagnoses compared to CR, but lower rates for individual data sources like HES and CPRD.
  • The research concludes that while combined primary and secondary care data may often reflect case status accurately, inconsistencies in diagnosis dates could affect cancer risk estimates and diagnostic pathways in studies.

Background: Understanding the risk of cancer after the diagnosis of another condition can present opportunities for earlier diagnosis. We examined the risk of cancer diagnosis conditional on prior diagnosis of atrial fibrillation (AF).

Methods: Linked electronic health records were used to identify patients aged ≥18 with new-onset AF and age-sex-matched controls.

Objective: To identify the prevalence and clinical features of leflunomide-associated peripheral neuropathy in patients with rheumatic disease over a 42-month observational period between January 1, 2016 and June 30, 2019.

Methods: A retrospective observational study was conducted using regional prescription data identifying all patients treated with leflunomide for rheumatic diseases in the Southern District Health Board of New Zealand. Medical records were used to identify patients who developed peripheral neuropathy while receiving treatment with leflunomide.

Findings from individual trials of physical rehabilitation interventions in critically ill adults have limited potential for meta-analysis and informing clinical decision-making because of the heterogeneity in selection and reporting of outcomes used for evaluation. The objective of this study was to determine a core outcome set (COS) for use in all future trials evaluating physical rehabilitation interventions delivered across the critical illness continuum of recovery. An international, two-round, online, modified Delphi consensus process, following recommended standards, was conducted.

Objectives: To investigate the role of comorbid chronic obstructive pulmonary disease (COPD) and symptom type on general practitioners' (GP's) symptom attribution and clinical decision-making in relation to lung cancer diagnosis.

Design: Vignette survey with a 2×2 mixed factorial design.

Setting: A nationwide online survey exploring clinical decision-making in primary care.

Article Synopsis
  • Insects are declining globally, especially in tropical forests, which have high biodiversity but are also experiencing significant biodiversity loss.
  • Most predictions about insect biodiversity rely on well-studied species, leaving many undescribed species unaccounted for, particularly in hyper-diverse tropical environments.
  • A study in Borneo found that 76% of collected staphylinid beetle species were undescribed, showing that these unknown species are more negatively affected by environmental changes caused by logging.

Colorectal cancer (CRC) is a leading cause of cancer mortality worldwide. Accurate cancer risk assessment approaches could increase rates of early CRC diagnosis, improve health outcomes for patients and reduce pressure on diagnostic services. The faecal immunochemical test (FIT) for blood in stool is widely used in primary care to identify symptomatic patients with likely CRC.

Background: Identifying patients presenting with nonspecific abdominal symptoms who have underlying cancer is a challenge. Common blood tests are widely used to investigate these symptoms in primary care, but their predictive value for detecting cancer in this context is unknown. We quantify the predictive value of 19 abnormal blood test results for detecting underlying cancer in patients presenting with 2 nonspecific abdominal symptoms.
