Abstract

Aims

To characterize a US population of patients with irritable bowel syndrome with constipation (IBS-C) or chronic idiopathic constipation (CIC) using CONTOR, a real-world longitudinal research platform that deterministically linked administrative claims data with patient-reported outcomes data among patients with these conditions.

甲状腺功能亢进症合并免疫性血小板减少性紫癜的5例病例临床分析

探讨甲状腺功能亢进症合并免疫性血小板减少性紫癜的患者服用丙基硫氧嘧啶(PTU)后对血小板的影响。停用丙基硫氧嘧啶,用地塞米松冲击治疗后,检测血小板计数。结果为所有患者的血小板均恢复正常。甲状腺功能亢进症患者体内抗体和自身免疫性血小板减少性紫癜的抗体具有部分同源性,抗甲状腺药物(PTU)对血小板也有破坏作用,因此,同时患有这2种疾病的患者,需选用对血小板影响小的药物,或者选用I131及手术治疗甲亢。     

Cost-effectiveness of dipeptidyl peptidase-4 inhibitor monotherapy versus sulfonylurea monotherapy for people with type 2 diabetes and chronic kidney disease in Thailand

Objective: With a high prevalence of chronic kidney disease (CKD) in type 2 diabetes (T2DM) in Thailand, the appropriate treatment for the patients has become a major concern. This study aimed to evaluate long-term cost-effective of dipeptidyl peptidase-4 (DPP-4) inhibitor monothearpy vs sulfonylurea (SFU) monotherapy in people with T2DM and CKD.

Methods: A validated IMS CORE Diabetes Model was used to estimate the long-term costs and outcomes. The efficacy parameters were identified and synthesized using a systematic review and meta-analysis. Baseline characteristics and cost parameters were obtained from published studies and hospital databases in Thailand. Costs were expressed in 2014?US Dollars. Outcomes were presented as an incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were performed to estimate parameter uncertainty.

Results: From a societal perspective, treatment with DPP-4 inhibitors yielded more quality-adjusted life years (QALYs) (0.024) at a higher cost (>66,000 Thai baht (THB) or >1,829.27 USD) per person than SFU, resulting in the ICER of >2.7 million THB/QALY (>74,833.70 USD/QALY). The cost-effectiveness results were mainly driven by differences in HbA1c reduction, hypoglycemic events, and drug acquisition cost of DPP-4 inhibitors. At the ceiling ratio of 160,000 THB/QALY (4,434.59 USD/QALY), the probability that DPP-4 inhibitors are cost-effective compared to SFU was less than 10%.

Conclusions: Compared to SFU, DPP-4 inhibitor monotherapy is not a cost-effective treatment for people with T2DM and CKD in Thailand.     

Patterns of care and burden of chronic idiopathic thrombocytopenic purpura in Brazil

Aims: Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.

Materials and methods: A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD?=?3.9571 BRL, from February 2016.)

Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine?+?prednisone, azathioprine?+?prednisone?+?danazol, and prednisone?+?dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm³ (SD?=?±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm³ (SD?=?±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm³ (SD?=?±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range?=?0–2,020.77 vs USD 9.51/month, range?=?0–192.64, respectively).

Limitations: This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.

Conclusions: The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited.     

Superhighway patrolman

This fictional prototype explores two of the future's major societal challenges: the delivery of healthcare to an increasingly ageing society; and the policing of a society, in which digital surveillance may predominate. It contrasts the author's vision of what life could be like in the United Kingdom in a decade's time (just as he contemplates retirement) with the simpler values of the 1980s, when he began his postgraduate career. The lyrics of the poignant 1982 Bruce Springsteen song, “Highway Patrolman” are used to bridge the epochs¹. The prototype relocates the two main ‘middle-America’ characters, brothers Joe and Frank Roberts, in London in the year 2025. Much has already changed politically and socially in ‘Western societies’ in the intervening period up to 2012, driven by the inexorable advances of technology. As further scientific advances drive us to an anticipated paradigm change,² one can only speculate on how society will advance, posing serious ethical dilemmas. Many of the changes will be positive. However, the story explores the potential negative consequences to the ageing population, in what appears to be a successful economy. Although somewhat pessimistic in outlook, a hopeful conclusion is that the ‘ties that bind’ will still predominate.     

Stress and consumer behavior

Although stress research has received increased attention in the behavioral and social sciences, it has been virtually ignored by marketing researchers. This paper attempts to advance the stress perspective as a useful framework in consumer research. First, the author presents theoretical and conceptual foundations of stress research. Second, the author develops a general conceptual model of the causes and consequences of stress on the basis of theory and research. The model serves as a blueprint for presenting theory and research on stress, organizing and interpreting findings of consumer studies in the context of stress theory, and developing propositions for needed research. Finally, the author provides a research agenda to guide future studies in this area.     

Shopping enjoyment and store shopping modes: The moderating influence of chronic time pressure

The objectives of this study were to investigate: (a) whether shopping enjoyment has a differential influence on two key store shopping modes (browsing vs. bargain hunting); (b) whether the level of chronic time pressure moderates the influence of shopping enjoyment on each shopping mode; and (c) whether each of the shopping modes has a differential influence on hedonic shopping value. Data were collected from a sample of US store shoppers (n=1009). Results revealed that the influence of shopping enjoyment was much stronger on the browsing mode than on the bargain hunting mode. In turn, the browsing mode exerted a stronger influence on hedonic shopping value. Also, this study confirmed that the level of chronic time pressure significantly moderated the influence of shopping enjoyment on the browsing mode. Implications for brick-and-mortar retailers were discussed with suggestions for future research.
