The title compound, C21H22O5, crystallizes with three molecules in the asymmetric unit. In one molecule, two methyl groups are disordered over two positions with a site occupation factor of 0.72 (2) for the major occupancy site. The benzene rings make dihedral angles of 35.3 (6), 29.7 (6) and 40.6 (7)° in the three molecules.

Additional approaches are needed to identify and provide targeted interventions to populations at continued risk for HIV-associated mortality. We sought to describe care utilization and mortality following an index hospitalization for people with HIV in South Africa.
We conducted a prospective cohort study among hospitalized patients admitted to medicine wards at a single hospital serving a large catchment area. Participants were followed to 6 months post-discharge. Hospital records were used to describe overall admission numbers and inpatient mortality. Poisson regression was used to assess for associations between readmission or death and independent variables.
Of 124 enrolled participants, 121 lived to hospital discharge. At the time of discharge the median length of stay of sampled patients was 5.5 days and 105 (87%) participants were referred for follow-up, most within 2 weeks of discharge. By 6 months post-discharge, only 18% of participants had attended the clinic to which they were referred and within the referred timeframe; 64 (53%) had been readmitted at least once and 31 (26%) had died. Self-reported skipping care due to difficulty in access (relative risk 1.3, p = 0.02) and not attending follow-up care on time or at the scheduled clinic or not attending clinic at all (relative risk 1.8 and 2.4, respectively, p = 0.001) were associated with readmission or mortality.
The post-hospital period is a period of medical vulnerability and high mortality. Improving post-hospital retention in care may reduce post-hospital mortality.

The title compound, C22H18N4OS, crystallized with four independent molecules (A, B, C and D) in the asymmetric unit. All four molecules have a Z conformation about the C=N bond with the benzyl ring being inclined to the indoline ring mean planes by 73.4 (2), 77.9 (2), 73.2 (2) and 77.2 (2)° in molecules A, B, C and D, respectively. In molecules A and B, the phenyl ring is inclined to the mean plane of the indoline ring mean plane by 12.0 (2) and 12.2 (2)°, respectively. However, in molecules C and D, the same dihedral angles are larger, viz. 37.3 (2) and 36.4 (2)°, respectively. Consequently, the benzyl and phenyl rings are almost normal to one another in molecules A and B [dihedral angles = 80.3 (3) and 87.1 (3)°, respectively], while in molecules C and D, the same dihedral angles are only 48.8 (2) and 43.8 (3)°, respectively. There is an intramolecular N—H⋯O hydrogen bond in each molecule with an S(6) ring motif. There are also short intramolecular N—H⋯N and C—H⋯S contacts in each molecule. In the crystal, molecules are linked via C—H⋯S hydrogen bonds and C—H⋯π interactions, forming a three-dimensional structure. The crystal was refined as a non-merohedral twin with a final BASF value of 0.110 (1).
