    PICO question In dogs diagnosed with osteoarthritis (OA), how safe is treatment with bedinvetmab, when compared to a placebo and how effective in long-term reduction of the severity of the clinical signs associated with OA-related pain?   Clinical bottom line Category of research Treatment. Number and type of study designs reviewed Two papers were critically reviewed. One was a randomised, blinded, multi-arm laboratory safety study; the other a multi-center field trial consisting of a block-randomised, double blind, placebo-controlled phase, followed by a non-comparative, open-label case series study. Strength of evidence Weak. Outcomes reported One study rated the reduction of the severity of clinical signs associated with OA pain using owner Canine Brief Pain Inventory (CBPI) ratings and non-validated veterinary clinical assessments (VCAs). Safety was addressed by evaluating adverse health effects (AHEs), concentration of antidrug antibodies (ADAs), and clinical pathology. Significant improvements in pain scores and VCAs were reported in this treatment study. The second safety-only study used clinical observation to evaluate AHEs. Both studies reported AHEs. Conclusion A single study suggests that treatment with bedinvetmab is effective. Two studies support the drug having few AHEs. Both studies have significant design limitations preventing the evaluation of bedinvetmab effectiveness. There is weak / inconclusive evidence for long-term efficacy and short-term safety of OA treatment with bedinvetmab. The decision to use bedinvetmab remains dependent on the judgement and experience of the clinician. How to apply this evidence in practice The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources. Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care

    Data from: Spiders spinning electrically charged nano-fibres

    Most spider threads are on the micrometre and sub-micrometre scale. Yet, there are some spiders that spin true nano-scale fibres such as the cribellate orb spider, Uloborus plumipes. Here, we analyse the highly specialized capture silk-spinning system of this spider and compare it with the silk extrusion systems of the more standard spider dragline threads. The cribellar silk extrusion system consists of tiny, morphologically basic glands each terminating through exceptionally long and narrow ducts in uniquely shaped silk outlets. Depending on spider size, hundreds to thousands of these outlet spigots cover the cribellum, a phylogenetically ancient spinning plate. We present details on the unique functional design of the cribellate gland–duct–spigot system and discuss design requirements for its specialist fibrils. The spinning of fibres on the nano-scale seems to have been facilitated by the evolution of a highly specialist way of direct spinning, which differs from the aqua-melt silk extrusion set-up more typical for other spiders
