Efficacy of a Pocket Pulse Oximeter and a Digital Pulse Oximeter as Screening Tools for Type 2 Diabetes Patients with Asymptomatic Lower Extremity Arterial Disease.

The risk of developing lower extremity arterial diseases (LEAD) increases by 2-4 folds in patients with diabetes mellitus. Diabetic individuals with LEAD are more likely than non-diabetic individuals to have limb amputations, and they have a higher risk of cardiovascular and cerebrovascular problems. The present study sought to assess the efficacy of two pulse oximeters, a high-quality standard digital pulse oximeter and an inexpensive pocket pulse oximeter, to detect LEAD in patients with diabetes mellitus.

Crystal structure of 15,16-ep-oxy-7β,9α-di-hydroxy-labdane-13(16),14-dien-6-one.

In the title mol-ecule, C20H30O4, both cyclo-hexane rings adopt chair conformations. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds forming chains along [100]. In addtion, an intra-molecular O-H⋯O hydrogen bond forms an S(5) ring.

Crystal structure of 4-[(E)-(4-chloro-benzyl-idene)amino]-3-(2-methyl-benz-yl)-1H-1,2,4-triazole-5(4H)-thione.

In the title mol-ecule, C17H15ClN4S, the benzene rings form dihedral angles of 16.6 (1) and 77.2 (1)° with the triazole ring.

3-Anilinothio-carbonyl-4-hydroxy-chromen-2-one.

The geometrical parameters of the title compound, C(16)H(11)NO(3)S, are in the usual ranges. The two aromatic residues are not coplanar and are twisted by a dihedral angle of 66.63 (6)°.

(E)-3-(4-Bromo-phen-yl)-1-(3,4-dichloro-phen-yl)prop-2-en-1-one.

The mol-ecule of the title compound, C(15)H(9)BrCl(2)O, is shown to be the E isomer, with the 3,4-dichloro-benzoyl and p-bromo-phenyl substituents in trans positions with respect to the chalcone olefin bond. The mol-ecule is non-planar, the two aromatic rings forming a dihedral angle of 49.58 (1)°.
