General practice variation in spirometry testing among patients receiving first-time prescriptions for medication targeting obstructive lung disease in Denmark:a population-based observational study

BACKGROUND: Spirometry testing is essential to confirm an obstructive lung disease, but studies have reported that a large proportion of patients diagnosed with COPD or asthma have no history of spirometry testing. Also, it has been shown that many patients are prescribed medication for obstructive lung disease without a relevant diagnosis or spirometry test registered. General practice characteristics have been reported to influence diagnosis and management of several chronic diseases. However, these findings are inconsistent, and it is uncertain whether practice characteristics influence spirometry testing among patients receiving medication for obstructive lung disease. The aim of this study was therefore to examine if practice characteristics are associated with spirometry testing among patients receiving first-time prescriptions for medication targeting obstructive lung disease. METHODS: A national register-based cohort study was performed. All patients over 18 years receiving first-time prescriptions for medication targeting obstructive lung disease in 2008 were identified and detailed patient-specific data on sociodemographic status and spirometry tests were extracted. Information on practice characteristics like number of doctors, number of patients per doctor, training practice status, as well as age and gender of the general practitioners was linked to each medication user. RESULTS: Partnership practices had a higher odds ratio (OR) of performing spirometry compared with single-handed practices (OR 1.24, CI 1.09-1.40). We found a significant association between increasing general practitioner age and decreasing spirometry testing. This tendency was most pronounced among partnership practices, where doctors over 65 years had the lowest odds of spirometry testing (OR 0.25, CI 0.10-0.61). Training practice status was significantly associated with spirometry testing among single-handed practices (OR 1.40, CI 1.10-1.79). CONCLUSION: Some of the variation in spirometry testing among patients receiving first-time prescriptions for medication targeting obstructive lung disease was associated with practice characteristics. This variation in performance may indicate a potential for quality improvement

A randomized, open-label comparison of once-weekly insulin icodec titration strategies versus once-daily insulin glargine u100

OBJECTIVE Insulin icodec is a novel once-weekly basal insulin analog. This trial investigated the efficacy and safety of icodec using different once-weekly titration algorithms. RESEARCH DESIGN AND METHODS This was a phase 2, randomized, open-label, 16-week, treat-to-target study. Insulin-naive adults (n = 205) with type 2 diabetes and HbA1c 7–10% while treated with oral glucose-lowering medications initiated once-weekly icodec titrations A (prebreakfast self-measured blood glucose target 80–130 mg/dL; adjustment ±21 units/week; n = 51), B (80–130 mg/dL; ±28 units/week; n = 51), or C (70–108 mg/dL; ±28 units/week; n = 52), or once-daily insulin glargine 100 units/mL (IGlar U100) (80–130 mg/dL; ±4 units/day; n = 51), all titrated weekly. Percentage of time in range (TIR) (70–180 mg/dL) during weeks 15 and 16 was measured using continuous glucose monitoring. RESULTS TIR improved from baseline (means: A, 57.0%;B,55.2%;C,51.0%; IGlar U100, 55.3%) to weeks 15 and 16 (estimated mean: A, 76.6%; B,83.0%; C,80.9%; IGlar U100, 75.9%). TIR was greater for titration B than for IGlar U100 (estimated treatment difference 7.08%-points; 95% CI 2.12 to 12.04; P = 0.005). No unexpected safety signals were observed. Level 2 hypoglycemia (<54 mg/dL) was low in all groups (0.05, 0.15, 0.38, 0.00 events per patient-year of exposure for icodec titrations A, B, and C and IGlar U100, respectively), with no episodes of severe hypoglycemia. CONCLUSIONS Once-weekly icodec was efficacious and well tolerated across all three titration algorithms investigated. The results for icodec titration A (80–130 mg/dL; ±21 units/week) displayed the best balance between glycemic control and risk of hypoglycemia

Mobile encounters:bus 5A as a cross-cultural meeting place

The paper explores modes of encounters in the everyday practice of bus travel. Particularly, it addresses cross-cultural encounters located in the tension between familiarity and difference, between inclusion and exclusion. The paper is located in contemporary thoughts, approaching public transport not only as a moving device but also as a social arena. Furthermore, the bus is simultaneously perceived as a public space, at once composite, contradictory and heterogeneous, and as a meeting place involving ‘Throwntogetherness’. The encounters analysed are bodily, emotional charged and outspoken meetings between passengers, with the socio-materiality of the bus and drivers as co-riders and gatekeepers

The state of the art: immune-mediated mechanisms of monoclonal antibodies in cancer therapy

A number of antibody products have now become accepted as effective anti-cancer therapies. Despite being mainly designed to act by inhibiting functional tumour antigens, there is increasing evidence that Fc-mediated engagement of the immune system is an important contributor to the efficacy of several of these therapies. The optimisation of this engagement offers the potential not only to augment efficacy against existing targets, but also to exploit non-functional tumour antigens. Antibodies that achieve efficacy wholly or predominantly through Fc-mediated mechanisms, represent rich opportunities for future therapeutics in oncology. This mini review summarises some of the key challenges, which need to be addressed to select the most effective molecules. These include the identification of optimal antibody characteristics and improvement of the drug discovery process, in particular, the relevance and predictive power of existing in vitro and in vivo screening methods. Advances in our understanding of tumour immunobiology and successful application of technologies designed to enhance immune system engagement will further aid this process
