Introduction: This study aims to report on clinical outcomes and 30-day mortality of patients with neck of femur fracture during COVID-19 pandemic and compare the outcomes in a cohort during the same period prior to the pandemic.
Material and Methods: The study included 66 patients with hip fracture over the age of 60 years, presented between 1st March and 15th May 2020 and matched with the patients with hip fractures (75 patients) managed during the corresponding period in 2019 as control. Data was collected on demographics, comorbidities, COVID-19 status, procedures and mortality and complications.
Results: Thirty-day mortality following hip surgery was 13.6% during COVID-19 pandemic with all the mortalities in patients with ASA Grade 3 and 4. Mortality was considerably high for intracapsular fracture (20%) but highest in cemented hemiarthroplasty (20%). One third of the hip fractures operated in COVID-19 designated theatre died within 30 days of surgery. Thirty-day mortality rate for COVID-19 positive hip fracture patients were 55.5%. There has been higher 30-day mortality for hip surgeries during COVID-19 pandemic with positive correlation between patient's COVID-19 test status and 30-day mortality following hip surgeries.
Conclusion: There is strong association between 30-day mortality and the designated theatre (Clean/COVID) where the patients were operated on with higher mortality for intracapsular neck of femur fractures with significant mortality associated with cemented hemiarthroplasty particularly among symptomatic or COVID-19 positive patients. Therefore, adoption of a multidisciplinary approach is recommended to optimally balance the risk-benefit ratio for planning of management of hip fractures while considering patient's peri-operative outcomes.

The global distribution of tetrapods reveals a need for targeted reptile conservation

The distributions of amphibians, birds and mammals have underpinned global and local conservation priorities, and have been fundamental to our understanding of the determinants of global biodiversity. In contrast, the global distributions of reptiles, representing a third of terrestrial vertebrate diversity, have been unavailable. This prevented the incorporation of reptiles into conservation planning and biased our understanding of the underlying processes governing global vertebrate biodiversity. Here, we present and analyse the global distribution of 10,064 reptile species (99% of extant terrestrial species). We show that richness patterns of the other three tetrapod classes are good spatial surrogates for species richness of all reptiles combined and of snakes, but characterize diversity patterns of lizards and turtles poorly. Hotspots of total and endemic lizard richness overlap very little with those of other taxa. Moreover, existing protected areas, sites of biodiversity significance and global conservation schemes represent birds and mammals better than reptiles. We show that additional conservation actions are needed to effectively protect reptiles, particularly lizards and turtles. Adding reptile knowledge to a global complementarity conservation priority scheme identifies many locations that consequently become important. Notably, investing resources in some of the world's arid, grassland and savannah habitats might be necessary to represent all terrestrial vertebrates efficiently.
