The insect apocalypse: ‘Our world will grind to a halt without them’

Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they performI have been fascinated byinsects all my life. One of my earliest memories is of finding, at the age of five or six, some stripy yellow-and-black caterpillars feeding on weeds in the school playground. I put them in my empty lunchbox, and took them home. Eventually they transformed into handsome magenta and black moths. This seemed like magic to me – and still does. I was hooked.In pursuit of insects I have travelled the world, from the deserts of Patagonia to the icy peaks of Fjordland in New Zealand and the forested mountains of Bhutan. I have watched clouds ofbirdwing butterflies sipping minerals from the banks of a river in Borneo, and thousands of fireflies flashing in synchrony at night in the swamps of Thailand. At home in my garden in Sussex I have spent countless hours watching grasshoppers court a mate and see off rivals, earwigs tend their young, ants milk honeydew from aphids, and leaf-cutter bees snip leaves to line their nests.Continue reading...

Conclusion: Certain components of online reviews are significantly correlated with ICH-CAHPS measures of patient experience. Additionally, online reviews come with narrative comments that can offer specific insights into positive and negative aspects of patient care that cannot always be elucidated by numeric survey questions. Online reviews may have utility as an adjunctive source of information to patient experience surveys such as the ICH-CAHPS.

Conclusion: Identifying hospitals that are consistently performing poorly and hospitals consistently performing well will allow administrators and clinicians to focus their efforts including budgetary to where improvements are needed. Patient care and the reduction of HAIs are a priority for health care institutions. While the results are similar to those reported by NYS, this approach can be used more comprehensively and can be interpreted more easily by administrators and practitioners. Health care administrators and clinicians may find the information useful to address infection rates. Hospitals consistently perform...

Conclusions: Our findings question the validity of using NIS and other administrative databases for health services and outcomes research that rely on certain diagnostic procedures. Unfortunately, the NIS does not provide granular data that can control for differences in diagnostic procedure use, which can lead to surveillance bias. Researchers and policy makers must understand and acknowledge the limitations inherent in these databases, when used for pay-for-performance initiatives and hospital benchmarking.

This study aimed to explore the effects of text enhancement on reduction of confusion caused by look-alike drug names through systematic review and meta-analysis. Methods: We searched 5 databases (from database inception to January 2020) for empirical studies that examined the effects of text enhancement on reduction of look-alike drug name–induced drug name confusion. The pooled outcome data were analyzed using either meta-analysis or a narrative synthesis approach. Results: From the 351 identified articles, 11 articles representing 20 individual trials were included. Five basic text enhancement method...
