ABSTRACT
BACKGROUND: Psoriasis (Pso) and atopic dermatitis (AD) are chronic skin diseases that result in significant physical and psychological impairment, financial burden, and loss of quality of life. According to previous data, there are regional differences in healthcare. OBJECTIVES: The aim was to analyse the epidemiology as well as the treatment of insured people with Pso and AD in Germany in a regional comparison. METHODS: Data of the insurance company Techniker Krankenkasse for the year 2019 regarding treatment prevalences as well as drug prescriptions on the regional level for all physicians were examined. RESULTS: In 2019 the overall prevalence of Pso was 2.5% (about 2 million insured people in Germany) and AD was 4.2% (about 3.6 million insured people). In Pso, new guideline-compliant drugs were frequently utilised, yet systemic glucocorticosteroids (GCS) were still disproportionally prescribed. Regionally, there were pronounced disparities with higher prescription rates of the new drugs in the north and east. Insured people with AD most frequently received topical GCS (approx. 88%), of which most were class III (66%), and significantly less frequently calcineurin inhibitors (<â¯10%), which also conform to guidelines. Systemically, GCS were by far most commonly used (about 25% of all insured people with drug prescriptions). Dupilumab, the only long-term drug approved in 2019, was very rarely prescribed, accounting for less than 1%. Again, large regional differences similar to Pso were found. CONCLUSION: Pso and AD show relevant disparities and gaps in drug care in the regional comparison despite uniform national guidelines and patient needs. The barriers to appropriate modern pharmaceuticals need to be clarified and mitigated.

High resolution spectra of the 0-0 band of the [18.6]3.5 - X(1)4.5 transition of uranium monofluoride, UF, obtained using a laser ablation spectrometer, showed a perturbation in the upper state. Examination of the Stark and Zeeman effects yielded permanent electric dipole moments of 2.01 and 1.88 D and magnetic g-factors of 3.28 and 3.26 for the ground and excited states, respectively. Both the dipole moment and g-factor of the ground state are in good agreement with ab initio calculations [I. O. Antonov and M. C. Heaven, J. Phys. Chem. A 117, 9684 (2013)]. The Zeeman effect results confirm that the ground state arises primarily from the U(+)(5f (3)7s(2 4)I(4.5))F(-) configuration and suggest several possible configurations for the upper state.
ABSTRACT
We report the measurement of a jet-cooled electronic spectrum of the silicon trimer. Si(3) was produced in a pulsed discharge of silane in argon, and the excitation spectrum examined in the 18 000-20 800 cm(-1) region. A combination of resonant two-color two-photon ionization (R2C2PI) time-of-flight mass spectroscopy, laser-induced fluorescence/dispersed fluorescence, and equation-of-motion coupled-cluster calculations have been used to establish that the observed spectrum is dominated by the 1(3)A(1)" - ã (3)A(2)' transition of the D(3h) isomer. The spectrum has an origin transition at 18,600 ± 4 cm(-1) and a short progression in the symmetric stretch with a frequency of â¼445 cm(-1), in good agreement with a predicted vertical transition energy of 2.34 eV for excitation to the 1(3)A(1)" state, which has a calculated symmetric stretching frequency of 480 cm(-1). In addition, a â¼505 cm(-1) ground state vibrational frequency determined from sequence bands and dispersed fluorescence is in agreement with an earlier zero-electron kinetic energy study of the lowest D(3h) state and with theory. A weaker, overlapping band system with a â¼360 cm(-1) progression, observed in the same mass channel (m/z = 84) by R2C2PI but under different discharge conditions, is thought to be due to transitions from the (more complicated) singlet C(2v) ground state ((1)A(1)) state of Si(3). Evidence of emission to this latter state in the triplet dispersed fluorescence spectra suggests extensive mixing in the excited triplet and singlet manifolds. Prospects for further spectroscopic characterization of the singlet system and direct measurement of the energy separation between the lowest singlet and triplet states are discussed.
ABSTRACT
The Q(4) and R(4) branch features of the (0,0)D (5)Delta(4)-X (5)Delta(4) band system and the Q(3) and R(3) branch features of the (0,0)D (5)Delta(3)-X (5)Delta(3) band system of iron monoxide FeO have been studied by optical Stark spectroscopy. The Stark splittings in the high resolution laser induced fluorescence spectra were analyzed to produce values for the magnitude of the permanent electric dipole moments /mu/ of 4.50+/-0.03, 4.29+/-0.05, 2.53+/-0.04, and 2.58+/-0.06 D for the X (5)Delta(4) (nu=0), X (5)Delta(3) (nu=0), D (5)Delta(4) (nu=0), and D (5)Delta(3) (nu=0) states, respectively. The results are compared to several ab initio predictions and to FeC. The qualitative trends are explained in terms of a molecular orbital correlation picture.
ABSTRACT
Numerous branch features in the (0,0) A 2Pi-X 2Sigma+ band system of calcium monohydride CaH have been studied by optical Stark spectroscopy. The Stark shifts, Stark splittings, and appearance of electric-field-induced transitions in the high resolution laser-induced fluorescence spectra are analyzed to produce values for the magnitude of the permanent electric dipole moments mid R:micromid R: of 2.94(16) D and 2.372(12) D for the X 2Sigma+(v=0) and A 2Pi(v=0) states, respectively. A comparison with values predicted from a semiempirical electrostatic model and previous ab initio calculations for mid R:micromid R: (X 2Sigma+) is presented. The change in mid R:micromid R: upon excitation from the X 2Sigma+ state to the A 2Pi state is rationalized using a simple molecular orbital description.
