Hey Rick, thanks. Yes. So, I think as we think about the flow of the quarter, what we saw during the quarter, and I think what we'll probably see continuously here for a while, until things at a macro level get completely normalized is still a bit of chop -- month to month, a little bit of choppiness obviously, producing really great growth in the end. But it's not -- it hasn't been what I would call super stable from day to day, from month to month. Certainly affected by the waning portion of RSV in the first part of the quarter, followed by I would say a much, much more normalized environment when it comes to respiratory illness. I think that's out of the news, as we're all seeing. But we have not seen the improvement that I think some other companies are reporting on the adult side, in hospital -- children's hospital throughput. We still remained hampered throughout the quarter with surgeons’ capacity to be able to get a long time and get particularly elective procedures through, despite the elective procedures really driving strong performance for us. And so, I think our guides still anticipates that we will have staffing challenges throughout the year. And like I said earlier, I think until we see really structural change that's sustainable, we want to remain pretty conservative with respect to what we see, particularly as we enter into a second quarter, where we have a pretty tough comp, if you remember last year, we did very, very well. We left Q2 thinking everything was completely normal and obviously it wasn't in the back half of the year with RSV and staffing. So, we see staffing situations changed, I think fairly consistently, we just remain optimistic but a bit cautious about our hospitals capacity to move a lot of the elective cases through in the really busy summer months of June, July and August. Last thing I would comment on related to the international. International obviously grew very substantially but -- primarily because of MDO and Pega, but the demand for products, particularly on the scoli really high. I would say we were a little disappointed that international wasn't better, but it was, I think entirely due to some timing, not just a fed orders, but even a couple big restock orders particularly on the scoli side. And that's not demand that's going away. We've got a pretty good look at what Q2 looks like. And I think we feel really confident about how international could impact the business positively through the last three quarters of the year.
