RESUMO

Drug therapy in patients who have undergone bariatric surgery is challenging. We aimed to investigate the patients' perspective on their drug therapy. This should allow deriving tailored measures to better support patients and their healthcare professionals with drug therapy after bariatric surgery. We conducted a quantitative telephone-based interview study with patients who have undergone bariatric surgery. The interview consisted of assessments in three parts: (i) current drug therapy: prescription, administration and adherence, (ii) changes after bariatric surgery and (iii) adverse events. (i) The 105 enrolled patients were taking a median of 10 (range: 3-30) drugs. In 1017 of 1080 drugs (94%), expectations in drug effectiveness were (rather) met. Of the 105 patients, 27% reported difficulties in drug administration, 44% forgot to take their drugs at least one time and 20% reported deviations from the prescription. (ii) Sixteen percent of the patients observed changes in drug effectiveness or tolerability-additionally to therapy adjustment by physicians. (iii) Seventy-four percent recognised at least one adverse event right before and/or after bariatric surgery, most frequently in gastrointestinal disorders. Patients who have undergone bariatric surgery have to deal with many difficulties in drug handling and adverse events. Our study emphasises the need for better and more individual support for patients with their drug therapy after bariatric surgery and, therefore, suggests a multidisciplinary approach that includes pharmacists. The stronger involvement of the patients' perspective seems to be a valuable source in research and practice.

RESUMO

Better and balanced information strategies supporting cardiovascular patients' adherence are required. Cardiovascular drugs have outstanding morbidity and mortality benefits. This can be counteracted by patients' perceptions of risks. Drug information should help the patient but not fuel unwarranted fears. We performed a cross-sectional survey of patients admitted to a cardiology ward. We evaluated (i) the patients' general benefit-risk estimation of their pharmacotherapy; (ii) views on benefits; (iii) views on risks; and (iv) information sources. Additionally, we assessed aspects of anxiety and depression with the Patient Health Questionnaire-4 (PHQ-4). (i) 67 patients (66%) rated expected drug benefits higher than potential risks. (ii) 72% of benefits motivated the patients to take their medication as prescribed. Patients more frequently mentioned surrogate markers as benefits than clinical benefits (p < 0.001). (iii) 56% of risks mentioned were perceived as bothersome and 35% as concerning. Risks were more often perceived as bothersome and concerning by patients with higher PHQ-4 scores (p=0.016). (iv) Physicians were the most frequent information source of benefits (92% of patients) and risks (45%), and pharmacy staff for 27% and 14%, respectively. Laymen or media served as sources of information on benefits in 39%, for risks in 40%, and package leaflets in 26% and 36%. 42% of the patients would like to receive more information on benefits versus 27% on risks. Our results suggest that knowledge of benefits motivates patients to take their drugs as prescribed. There is already good information on surrogate markers for process control with active patient involvement. However, a lack of knowledge still exists in relation to clinical benefits. Regarding risks, it has been shown that patients with higher PHQ-4 scores are more likely to be bothered or concerned. Both emphases on clinical benefits and individualization depending on PHQ-4 scores may be valuable resources for patient counseling to support adherence.

RESUMO

BACKGROUND/AIMS: It is currently under debate whether aldosterone is able to induce fibrosis or whether it acts only as a cofactor under pathological conditions, e.g. as an elevated salt (NaCl) load. METHODS: We tested the interaction of 10 nM aldosterone, 15 mM NaCl and 1 µM ouabain using rat aorta smooth muscle cells (A10) with respect to the following parameters: necrosis, apoptosis, glucose-6-phosphate dehydrogenase (G6PD) and 6-phosphogluconate dehydrogenase activity, glutathione (GSH) content, collagen and fibronectin homeostasis and intracellular calcium distribution. RESULTS: Necrosis rates were increased after 48 h of incubation with aldosterone, salt or ouabain and in the combination of aldosterone and salt or ouabain. Apoptosis rates were decreased. A reduced defense capacity against oxidative stress was mirrored in the decreased G6PD activity and GSH content. Collagen III or fibronectin synthesis rates were unchanged, but gelatinase activity was increased resulting in a decreased media collagen III and fibronectin content. Calcium stores were increased by aldosterone in combination with ouabain. CONCLUSION: Aldosterone and salt per se can lead to cell injury that is aggravated in combination or with cardiotonic steroids. In cooperation with other vascular cells, this can generate a permissive milieu enabling aldosterone or salt to promote more extensive vascular injury.
