- OBJECTIVE: To evaluate the onset of analgesic effect for a new formulation of ibuprofen sodium dihydrate versus conventional ibuprofen (ibuprofen acid). MATERIALS AND METHODS: In this randomized, double-blind, double-dummy, crossover trial, patients requiring surgical removal of two impacted or partially impacted mandibular third molars received: ibuprofen sodium dihydrate 400 mg plus conventional ibuprofen placebo (Group 1); or conventional ibuprofen 400 mg plus ibuprofen sodium dihydrate placebo (Group 2) following the first surgery. Patients were then crossed over to the alternative treatment. RESULTS: 72 patients were enrolled in Group 1 and 72 patients in Group 2. Ibuprofen sodium dihydrate produced faster initial pain relief than conventional ibuprofen as assessed by time to first pain relief (24.6 vs. 30.5 minutes; p = 0.004), and patient-assessed pain relief at 15 minutes ("some" to "complete" pain relief: 43% vs. 29%; p < 0.001) and 30 minutes (82% vs. 63%; p < 0.001) and pain intensity at 30 minutes (p < 0.001). Substantial pain relief with ibuprofen sodium dihydrate was twice that of conventional ibuprofen at 30 minutes (11% vs. 5%; not significant); 29% and 33% of patients did not reach substantial pain relief at 120 minutes. There were no adverse events leading to treatment discontinuation and only two serious adverse events (oral abscess and facial paresis with conventional ibuprofen) considered unrelated to treatment. CONCLUSIONS: Ibuprofen sodium dihydrate was as effective as conventional ibuprofen, but had a faster onset of initial pain relief and significantly reduced pain intensity within the first 30 minutes after administration, providing rapid clinically meaningful pain relief for patients.

- BackgroundCOPD has increased in prevalence worldwide over several decades until the first decade after the millennium shift. Evidence from a few recent population studies indicate that the prevalence may be levelling or even decreasing in some areas in Europe. Since the 1970s, a substantial and ongoing decrease in smoking prevalence has been observed in several European countries including Sweden. The aim of the current study was to estimate the prevalence, characteristics and risk factors for COPD in the Swedish general population. A further aim was to estimate the prevalence trend of COPD in Northern Sweden from 1994 to 2009.MethodsTwo large random population samples were invited to spirometry with bronchodilator testing and structured interviews in 2009–2012, one in south-western and one in northern Sweden, n = 1839 participants in total. The results from northern Sweden were compared to a study performed 15 years earlier in the same area and age-span. The diagnosis of COPD required both chronic airway obstruction (CAO) and the presence of respiratory symptoms, in line with the GOLD documents since 2017. CAO was defined as post-bronchodilator FEV1/FVC < 0.70, with sensitivity analyses based on the FEV1/FVC < lower limit of normal (LLN) criterion.ResultsBased on the fixed ratio definition, the prevalence of COPD was 7.0% (men 8.3%; women 5.8%) in 2009–2012. The prevalence of moderate to severe (GOLD ≥ 2) COPD was 3.5%. The LLN based results were about 30% lower. Smoking, occupational exposures, and older age were risk factors for COPD, whereof smoking was the most dominating risk factor. In northern Sweden the prevalence of COPD, particularly moderate to severe COPD, decreased significantly from 1994 to 2009, and the decrease followed a decrease in smoking.ConclusionsThe prevalence of COPD has decreased in Sweden, and the prevalence of moderate to severe COPD was particularly low. The decrease follows a major decrease in smoking prevalence over several decades, but smoking remained the dominating risk factor for COPD.

Sulphur abundances in halo giants from the [S I] line at 1082 nm and the [S I] triplet around 1045 nm

- Context. It is still debated whether or not the Galactic chemical evolution of sulphur in the halo follows the flat trend with [Fe/H] that is ascribed to the result of explosive nucleosynthesis in type II SNe. It has been suggested that the disagreement between different investigations of sulphur abundances in halo stars might be owing to problems with the diagnostics used, that a new production source of sulphur might be needed in the early Universe, like hypernovae, or that the deposition of supernova ejecta into the interstellar medium is time-delayed. Aims. The aim of this study is to try to clarify this situation by measuring the sulphur abundance in a sample of halo giants using two diagnostics: the S I triplet around 1045 nm and the [S I] line at 1082 nm. The latter of the two is not believed to be sensitive to non-LTE effects. We can thereby minimize the uncertainties in the diagnostic used and estimate the usefulness of the triplet for the sulphur determination in halo K giants. We will also be able to compare our sulphur abundance differences from the two diagnostics with the expected non-LTE effects in the 1045 nm triplet previously calculated by others. Methods. High-resolution near-infrared spectra of ten K giants were recorded using the spectrometer CRIRES mounted at VLT. Two standard settings were used, one covering the S I triplet and one covering the [S I] line. The sulphur abundances were individually determined with equivalent widths and synthetic spectra for the two diagnostics using tailored 1D model atmospheres and relying on non-LTE corrections from the litterature. Effects of convective inhomogeneities in the stellar atmospheres are investigated. Results. The sulphur abundances derived from both the [S I] line and the non-LTE corrected 1045 nm triplet favor a flat trend for the evolution of sulphur. In contrast to some previous studies, we saw no "high" values of [S/Fe] in our sample. Conclusions. We corroborate the flat trend in the [S/Fe] vs. [Fe/H] plot for halo stars found in some previous studies but do not find a scatter or a rise in [S/Fe] as obtained in other works. We find the sulphur abundances deduced from the non-LTE corrected triplet to be somewhat lower than the abundances from the [S I] line, possibly indicating too large non-LTE corrections. Considering 3D modeling, however, they might instead be too small. Moreover, we show that the [S I] line can be used as a sulphur diagnostic down to [Fe/H] similar to - 2.3 in giants.
