FEV1/FEV6 Cutoff Points to Avoid False Negatives When Using Portable Devices, PICO-6 and COPD-6, in COPD Detection in Primary Healthcare Services.

: Chronic obstructive pulmonary disease (COPD) is a frequent but underdiagnosed disease, primarily due to the lack of access to forced spirometry (FS) in primary care. Portable, easy-to-use expiratory flow meters like Piko-6 and COPD-6 that measure FEV, FEV, and FEV/FEV ratio provide an alternative. Given that Piko-6 and COPD-6 devices measure FEV but not FVC, the aim of the study is to determine the optimal cutoff value for the FEV/FEV ratio of each device to avoid false negatives when these devices are used for COPD screening in primary care (PC).

Strategies for Early Keratoconus Diagnosis: A Narrative Review of Evaluating Affordable and Effective Detection Techniques.

Keratoconus is a progressive corneal disorder that can lead to irreversible visual impairment if not detected early. Despite its high prevalence, early diagnosis is often delayed, especially in low-to-middle-income countries due to limited awareness and restricted access to advanced diagnostic tools such as corneal topography, tomography, optical coherence tomography, and corneal biomechanical assessments. These technologies are essential for identifying early-stage keratoconus, yet their high cost limits accessibility in resource-limited settings.
