Yes. Sure, Vik. Volume trends, again, I think it's been talked about a lot out there, and I'll just give our version. But certainly, the year started slow kind of building off of the slow finish to last year. As we kind of headed through into March and even April, there was really good momentum building there, and you heard very little about cancellations and staffing shortages and things like that. But then as we made our way through the second quarter, late in the quarter, kind of late May, early June, we started to hear again about higher cancellation rates related usually to COVID testing, sometimes to staffing issues. And we also have seen isolated areas of, we call it, staffing pressure, but in some cases, it's really longer vacations. I think we've got some people that -- whether it's the surgeons or their staffs, that have been kind of not doing a whole lot of vacation in the last few years. And I think in June and July, we saw, in some cases, kind of more significant vacation downtime than we have in the past in those months. And so those are some of the things that we've seen in the elective surgery area, really speaking about the U.S. And -- but we also have gotten really, really good signals about what's expected to happen in August and September. There's a kind of a better short-term trend in terms of cancellations, and the scheduling is suggesting that there's going to be a nice trend through the quarter in terms of people getting kind of back aggressively into a ramp of elective surgery. And then certainly, there's plenty of pent-up demand that people want to get at as we come down the stretch of the year here. On the P&R side, again, we get the secondary impact of those elective surgery trends on a part of that business. And then I think there's been a smaller effect that you do have some staffing pressure on different clinics out there that it was probably a little bit of a factor in the market in the first couple of quarters of the year as well.
