Emerging infectious diseases (EIDs) increasingly threaten global food security and public health. Despite technological breakthroughs, we are losing the battle with (re)emerging diseases as treatment costs and production losses rise. A horizon scan of diseases of crops, livestock, seafood and food-borne illness suggests these costs are unsustainable. The paradigm of coevolution between pathogens and particular hosts teaches that emerging diseases occur only when pathogens evolve specific capacities that allow them to move to new hosts. EIDs ought to be rare and unpredictable, so crisis response is the best we can do. mTOR activity Alternatively, the Stockholm Paradigm suggests that the world is full of susceptible but unexposed hosts that pathogens could infect, given the opportunity. Global climate change, globalized trade and travel, urbanization and land-use changes (often associated with biodiversity loss) increase those opportunities, making EID frequent. We can, however, anticipate their arrival in new locations and their behaviour once they have arrived. We can 'find them before they find us', mitigating their impacts. The DAMA (Document, Assess, Monitor, Act) protocol alters the current reactive stance and embodies proactive solutions to anticipate and mitigate the impacts of EID, extending human and material resources and buying time for development of new vaccinations, medications and control measures.Erythrodermic psoriasis (EP), which accounts for 1 to 2.25% of all psoriatic cases, typically occurs in patients with poor control of existing psoriasis. Secukinumab yields rapid and sustained improvements of signs and symptoms in patients with plaque psoriasis. Currently, clinical data on the treatment of EP with secukinumab are scarce. We describe two adult patients with severe EP, including one male and one female who were both ineligible for or resistant to acitretin or methotrexate treatment and had additional diseases. The patients underwent treatment with secukinumab using the standard regimen. After 4 weeks of treatment, a 75% reduction in the Psoriasis Area and Severity Index score (PASI 75) was achieved in both patients. Secukinumab was well tolerated and was continued for at least 32 weeks of treatment. We report the clinical use of secukinumab in the treatment of EP and review its potential role in the management of this severe condition.Mental healthcare providers face many difficult interactions with patients that can be emotionally demanding and have adverse effects on their well-being. Recent theoretical models suggest that the interpretation of stressful episodes may be more important for psychological adjustment than the nature of the episodes. This study examined whether care providers' interpretations of mechanical restraint episodes were related to their adjustment. We asked 80 mental healthcare providers to recall mechanical restraint episodes and to rate them on centrality to identity and positive and negative influence on self-understanding. They also completed scales measuring current symptoms of post-traumatic stress, depression, life satisfaction, and well-being. The results showed that care providers who interpreted mechanical restraint episodes as having a central negative influence on their identity experienced more symptoms of post-traumatic stress. Care providers who gave higher ratings of positive self-change following episodes reported more well-being. Our findings suggest, that considering care providers' subjective interpretations of episodes and not merely the objective facts surrounding them is critical if we wish to mitigate the negative emotional impact of episodes.Postradiation cutaneous angiosarcoma of the breast is a rare, delayed complication of adjuvant radiation treatment for breast carcinoma and is associated with a worse prognosis than the original primary cancer. Recent studies have characterized the diagnostic utility of MYC and NOTCH1 receptor expression as markers for secondary radiation-associated angiosarcomas. Herein, we report an exophytic secondary breast angiosarcoma with MYC and NOTCH1 immunoreactivity. This case illustrates the utility of these markers for the identification of radiation-associated angiosarcoma with MYC and NOTCH1 expression, potential for targeted therapy and need to identify patients for further studies of the clinicopathologic and prognostic significance.
Carboxyl/cholinesterases (CCEs) are thought to play a pivotal role in the degradation of sex pheromones and plant-derived odorants in insects, but their exact biochemistry and physiological functions remain unclear.

In this study, two paralogous antennae-enriched CCEs from Plutella xylostella (PxylCCE16a and 16c) were identified and functionally characterized. High-purity protein preparations of active recombinant PxylCCE16a and 16c have been obtained from Sf9 insect cells by Ni
affinity purification. Our results revealed that the purified recombinant PxylCCE016c is able to degrade two sex pheromone components Z9-14Ac and Z11-16Ac at 27.64 ± 0.79% and 24.40 ± 3.07%, respectively, while PxylCCE016a presented relatively lower activity. Additionally, a similar difference in activity was measured in plant-derived odorants. Furthermore, both CCEs displayed obvious preferences for the two sex pheromone components, especially on Z11-16Ac (K
values are in the range 7.82-45.06 μmol L
) which much lower than plant odorants (K
values are in the range 1290-4030 μmol L
). Furthermore, the activity of the two newly identified CCEs is pH-dependent. The activity at pH6.5 is obviously higher than that at pH5.0. Interestingly, only PxylCCE016c can be inhibited by a common esterase inhibitor triphenyl phosphate (TPP) with LC
of 1570 ± 520 μmol L
.

PxylCCE16c plays a more essential role in odorant degradation than PxylCCE16a. Moreover, the current study provides novel potential pesticide targets for the notorious moth Plutella xylostella. © 2021 Society of Chemical Industry.
