TL;DR: Although the statement that plain vitamin D is the treatment of choice for vitamin D deficiency is agreed, there is no high-level evidence of which vitamin D metabolites are safer and faster in normalizing sHPTH, and more importantly, the optimal dose of vitamin D3 capable of normalizing rapidly sHP TH is still being discussed and has not been established.
Abstract: point that there is no high-level evidence of which vitamin D metabolites are safer and faster in normalizing sHPTH, and more importantly, the optimal dose of vitamin D3 capable of normalizing rapidly sHPTH is still being discussed and has not been established. In addition, a number of studies have demonstrated that the commonly used doses of vitamin D ( 800 UI daily), also suggested by the drug industry, may fail to normalize PTH levels in older adults with sHPTH. The choice of calcitriol in the experimental design of our study was based mainly on the need to use a treatment that could rapidly resolve sHPTH and on the lack of available preparation of vitamin D3 at high concentrations in Italy at the time of the study. In conclusion, although we agree with the statement that plain vitamin D is the treatment of choice for vitamin D deficiency, we disagree with the interpretation of the manuscript given by Dr. Vieth, because the goal of identifying a treatment of choice for sHPTH was outside the scope of our study, whose most relevant outcome consists instead of the observation that persistence of sHPTH reduces BMD response to alendronate. To respond to the issue raised by Dr. Vieth, RCTs are needed to assess the vitamin D metabolite of choice in normalizing PTH.

TL;DR: In this paper, angle-resolved photoemission spectroscopy was used to show that the anisotropy of the pseudogap in k-space and the resulting arcs depend only on the ratio T/T*(x).
Abstract: The response of a material to external stimuli depends on its low-energy excitations. In conventional metals, these excitations are electrons on the Fermi surface—a contour in momentum (k) space that encloses all of the occupied states for non-interacting electrons. The pseudogap phase in the copper oxide superconductors, however, is a most unusual state of matter1. It is metallic, but part of its Fermi surface is ‘gapped out’ (refs 2, 3); low-energy electronic excitations occupy disconnected segments known as Fermi arcs4. Two main interpretations of its origin have been proposed: either the pseudogap is a precursor to superconductivity5, or it arises from another order competing with superconductivity6. Using angle-resolved photoemission spectroscopy, we show that the anisotropy of the pseudogap in k-space and the resulting arcs depend only on the ratio T/T*(x), where T*(x) is the temperature below which the pseudogap first develops at a given hole doping x. The arcs collapse linearly with T/T*(x) and extrapolate to zero extent as T→0. This suggests that the T=0 pseudogap state is a nodal liquid—a strange metallic state whose gapless excitations exist only at points in k-space, just as in a d-wave superconducting state.

TL;DR: The first measurement of the tau lepton polarization P-tau(D*) in the decay (B) over bar -> D* tau(-) (v) over b (tau) as well as a new measurement of the ratio of the branching fractions was reported in this paper.
Abstract: We report the first measurement of the tau lepton polarization P-tau(D*) in the decay (B) over bar -> D* tau(-) (v) over bar (tau) as well as a newmeasurement of the ratio of the branching fractions R(D*) = B((B) over bar -> D* tau(-) (v) over bar (tau)) / B((B) over bar -> D* l(-) (v) over bar (l)), where l(-) denotes an electron or a muon, and the tau is reconstructed in the modes tau(-) -> pi(-) v(tau) and tau(-) -> rho(-) v(tau). We use the full data sample of 772 x 10(6) B (B) over bar pairs recorded with the Belle detector at the (KEKB) over bar electron-positron collider. Our results, P-tau(D*) = -0.38 +/- 0.51 (stat)(-0.16)(+0.21) (syst) and R(D*) = 0.270 +/- 0.035 (stat)(- 0.025)(+0.028) (syst), are consistent with the theoretical predictions of the standard model.

TL;DR: The health systems in Hong Kong, Singapore, and Japan have generally been able to adapt, but their resilience could be affected if the COVID-19 epidemic continues for many more months and increasing numbers of people require services.
