Quantification of cAMP and cGMP analogs in intact cells: pitfalls in enzyme immunoassays for cyclic nucleotides
Immunoassays are routinely used as research tools to measure intracellular cAMP and cGMP concentrations. Ideally, this application requires antibodies with high sensitivity and specificity. The present work evaluates the cross-reactivity of commercially available cyclic nucleotide analogs with two non-radioactive and one radioactive cAMP and cGMP immunoassay. Most of the tested cyclic nucleotide analogs showed low degree competition with the antibodies; however, with Rp-cAMPS, 8-Br-cGMP and 8-pCPT-cGMP, a strong cross-reactivity with the corresponding cAMP and cGMP, respectively, immunoassays was observed. The determined EIA-binding constants enabled the measurement of the intracellular cyclic nucleotide concentrations and revealed a time- and lipophilicity-dependent cell membrane permeability of the compounds in the range of 10–30% of the extracellular applied concentration, thus allowing a more accurate prediction of the intracellular analog levels in a given experiment
Scholarly publishing depends on peer reviewers
The peer-review crisis is posing a risk to the scholarly peer-reviewed journal system. Journals have to ask many potential peer reviewers to obtain a minimum acceptable number of peers accepting reviewing a manuscript. Several solutions have been suggested to overcome this shortage. From reimbursing for the job, to eliminating pre- publication reviews, one cannot predict which is more dangerous for the future of scholarly publishing. And, why not acknowledging their contribution to the final version of the article published? PubMed created two categories of contributors: authors [AU] and collaborators [IR]. Why not a third category for the peer-reviewer

Systemic thrombolysis for acute, severe Budd-Chiari syndrome
Budd-Chiari syndrome (BCS) or hepatic venous outflow obstruction, is a rare and complex clinical entity, with diverse aetiology and a wide range of presentations. Its rarity and heterogeneity create significant challenges for evidence-based clinical decision-making, particularly in the even more infrequent setting of acute BCS presentation. Here we present the case of a young woman with acute, severe BCS, where treatment alternatives were limited due to a significant IVC thrombus burden. A clearly defined acute onset allowed the prompt use of systemic thrombolysis, conducted in consultation with a multi-disciplinary team of clinicians, with close monitoring for both treatment response and complications. Her treatment resulted in resolution of hepatic vein occlusion and prevention of the potentially significant clinical sequelae. We review the literature and discuss current opinion in the management of BCS
The relationship between patients’ perception of type 2 diabetes and medication adherence: a cross-sectional study in Japan
Systematic scoping review of patients’ perceived needs of health services for osteoporosis
Health service planners, administrators and providers need to understand the patients’ perspective of health services related to osteoporosis to optimise health outcomes. The aims of this study were to systematically identify and review the literature regarding patients’ perceived health service needs relating to osteoporosis and osteopenia. A systematic scoping review was performed of publications in MEDLINE, EMBASE, CINAHL and PsycINFO (1990–2016). Descriptive data regarding study design and methodology were extracted and risk of bias assessed. Aggregates of patients’ perceived needs of osteoporosis health services were categorised. Thirty-three studies (19 quantitative and 14 qualitative) from 1027 were relevant. The following areas of perceived need emerged: (1) patients sought healthcare from doctors to obtain information and initiate management. They were dissatisfied with poor communication, lack of time and poor continuity of care. (2) Patients perceived a role for osteoporosis pharmacotherapy but were concerned about medication administration and adverse effects. (3) Patients believed that exercise and vitamin supplementation were important, but there is a lack of data examining the needs for other non-pharmacological measures such as smoking cessation and alcohol. (4) Patients wanted diagnostic evaluation and ongoing surveillance of their bone health. This review identified patients’ needs for better communication with their healthcare providers. It also showed that a number of important cornerstones of therapy for osteoporosis, such as pharmacotherapy and exercise, are identified as important by patients, as well as ongoing surveillance of bone health. Understanding patients’ perceived needs and aligning them with responsive and evidence-informed service models are likely to optimise patient outcomes. © 2017 International Osteoporosis Foundation and National Osteoporosis Foundation
