Accuracy of surrogate outcomes in predicting true endpoints of surgical periodontal therapy. A narrative review with a 20‐year longitudinal analysis

Periodontology 2000, EarlyView.
Abstract Background Periodontal clinical trials commonly use surrogate end points (e.g., probing pocket depth [PPD], clinical attachment level [CAL], bleeding on probing [BoP], and composite scores such as the Periodontal Risk Score [PRS]) for efficiency, yet tooth loss, treatment burden/cost, and re‐treatment are the definitive patient‐relevant ...

Beyond biologic sex: Exploratory insights into the heterogeneity of hormonal and contextual drivers of periodontal and peri‐implant outcomes

Periodontology 2000, EarlyView.
Abstract Background Periodontal and peri‐implant diseases are multifactorial inflammatory conditions influenced by microbial, host, hormonal, genetic, and behavioral factors. Although sex‐based differences in immune and inflammatory responses are well recognized in medicine, the extent to which biologic sex and hormonal status influence the prevalence,

Ground mammal colonization of restored wildlife corridors in the tropical uplands of north‐eastern Australia

Restoration Ecology, EarlyView.
Abstract Introduction Since European settlement, Australia's Wet Tropics bioregion has been extensively cleared, leaving a mosaic of rainforest fragments, crops, pastures, orchards, and human settlement. Fragment isolation leads to declines in faunal diversity and genetic variability, effects potentially exacerbated by climate change. Restoring habitat

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.
