Corticotroph pituitary carcinoma with skeletal metastases masquerading as ectopic ACTH syndrome: a long and winding road to diagnosis.

Summary: Pituitary carcinoma is a rare type of malignancy and only accounts for 0.1-0.2% of all pituitary tumours. Most pituitary carcinomas are hormonally active and they are mostly represented by corticotroph and lactotroph carcinomas. Corticotroph carcinoma can present as symptomatic Cushing's disease or can evolve from silent corticotroph adenoma which is not associated with clinical or biochemical evidence of hypercortisolism. We hereby present a case of a bone-metastasized corticotroph pituitary carcinoma masquerading as an ectopic adrenocorticotropic hormone (ACTH) syndrome in a patient with a history of a non-functioning pituitary macro-adenoma. Our patient underwent two transsphenoidal resections of the primary pituitary tumour followed by external beam radiation therapy. Under hydrocortisone substitution therapy she developed ACTH-dependent hypercortisolism without arguments for recurrence on pituitary MRI and without central-to-peripheral ACTH-gradient on inferior petrosal sinus sampling, both suggesting ectopic production. Ultimately, she was diagnosed with an ACTH-secreting vertebral metastasis originating from the primary pituitary tumour. This case report demonstrates the complex pathophysiology of pituitary carcinoma and the long diagnostic work-up. Certain features in pituitary adenoma should raise the suspicion of malignancy. Learning points: The diagnosis of pituitary carcinoma can only be made based on documented metastasis, therefore, due to the often long latency period between the detection of the primary tumour and the occurrence of metastasis, the diagnostic work-up most often spans over multiple years. Pituitary carcinoma including corticotroph carcinoma is very rare in contrast to pituitary adenoma and only accounts for 0.1-0.2% of all pituitary tumours. Histopathology in pituitary adenoma should certainly accomplish the following goals: accurate tumour subtyping and assessment of tumoural proliferative potential. Repeated recurrence of pituitary adenoma after surgical resection, a discrepancy between biochemical and radiological findings, resistance to medical and radiation therapy, and silent tumours becoming functional are all hallmarks of pituitary carcinoma. Silent corticotroph adenomas are non-functioning pituitary adenomas that arise from T-PIT lineage adenohypophyseal cells and that can express adrenocorticotropic hormone on immunohistochemistry, but are not associated with biochemical or clinical evidence of hypercortisolism. Silent corticotroph adenomas exhibit a more aggressive clinical behaviour than other non-functioning adenomas. Treatment options for corticotroph carcinoma include primary tumour resection, radiation therapy, medical therapy, and chemotherapy. Sometimes bilateral adrenalectomy is necessary to achieve sufficient control of the cortisol excess.

Impact of activity trackers on secondary prevention in patients with coronary artery disease: a systematic review and meta-analysis.

AIMS: Coronary artery disease (CAD) is related to high rates of morbidity and mortality among cardiovascular diseases (CVDs). Activity trackers have been used in cardiac rehabilitation (CR) in the last years. However, their effectiveness to influence outcomes after CAD is debated. This review summarizes the latest data of impact of activity trackers on CVD risk and outcomes: peak oxygen consumption (VO2), major adverse cardiovascular events (MACE), quality of life (QoL), and low-density lipoprotein-cholesterol (LDL-C). METHODS AND RESULTS: Articles from 1986 to 2020 in English were searched by electronic databases (PubMed, Cochrane Library, and Embase). Inclusion criteria were: randomized controlled trials of CAD secondary prevention using an activity tracker which include at least peak VO2, MACE, QoL, or LDL-C as outcomes. Meta-analysis was performed. After removing duplicates, 604 articles were included and the screening identified a total of 11 articles. Compared to control groups, intervention groups with activity trackers significantly increased peak VO2 [mean difference 1.54; 95% confidence interval (CI) (0.50-2.57); P = 0.004] and decreased MACE [risk ratio 0.51; 95% CI (0.31-0.86); P = 0.01]. Heterogeneity was low (I2 = 0%) for MACE and high (I2 = 51%) for peak VO2. Intervention with an activity tracker also has positive impact on QoL. There was no between-group difference in LDL-C. CONCLUSION: CR using activity trackers has a positive and multi-faceted effect on peak VO2, MACE, and QoL in patients with CAD.

Automatic transmission of home blood pressure data can be effective in managing hypertension: a systematic review and meta-analysis.

Aims: Home blood pressure telemonitoring (HBPT) is a useful way to manage BP. Recent advances in digital technology to automatically transmit BP data without the patient input may change the approach to long-term BP treatment and follow-up. The purpose of this review is to summarize the latest data on the HBPT with automatic data transmission. Methods and results: Articles in English from 1980 to 2021 were searched by electronic databases. Randomized controlled trials comparing HBPT with automatic data transmission with usual BP management and including systolic BP (SBP) and/or diastolic BP (DBP) as outcomes in hypertension patients were included in the systematic review. A meta-analysis was conducted. After removing duplicates, 474 papers were included and 23 papers were identified. The HBPT with automatic data transmission had a significant beneficial impact on BP reduction (mean difference for office SBP -6.0 mm Hg; P < 0.001). Subgroup analyses showed that the studies using smartphone applications reduced BP significantly more in the intervention group than in the control group (standardized mean difference for office and home SBP -0.25; P = 0.01) as did the studies using HBPT other than the applications. Longer observation periods showed a sustained effect, and multidisciplinary cooperation was effective. Conclusion: This review suggests that a care path based on HBPT with automatic data transmission can be more effective than classical management of hypertension. In particular, the studies using smartphone applications have shown beneficial effects. The results support the deployment of digital cardiology in the field of hypertension management.

Efficacy of digital health interventions on depression and anxiety in patients with cardiac disease: a systematic review and meta-analysis.

Aims: Depression and anxiety have a detrimental effect on the health outcomes of patients with heart disease. Digital health interventions (DHIs) could offer a solution to treat depression and anxiety in patients with heart disease, but evidence of its efficacy remains scarce. This review summarizes the latest data about the impact of DHIs on depression/anxiety in patients with cardiac disease. Methods and results: Articles from 2000 to 2021 in English were searched through electronic databases (PubMed, Cochrane Library, and Embase). Articles were included if they incorporated a randomized controlled trial design for patients with cardiac disease and used DHIs in which depression or anxiety was set as outcomes. A systematic review and meta-analysis were performed. A total of 1675 articles were included and the screening identified a total of 17 articles. Results indicated that telemonitoring systems have a beneficial effect on depression [standardized mean difference for depression questionnaire score -0.78 (P = 0.07), -0.55 (P < 0.001), for with and without involving a psychological intervention, respectively]. Results on PC or cell phone-based psychosocial education and training have also a beneficial influence on depression [standardized mean difference for depression questionnaire score -0.49 (P = 0.009)]. Conclusion: Telemonitoring systems for heart failure and PC/cell phone-based psychosocial education and training for patients with heart failure or coronary heart disease had a beneficial effect especially on depression. Regarding telemonitoring for heart failure, this effect was reached even without incorporating a specific psychological intervention. These results illustrate the future potential of DHIs for mental health in cardiology.

Impact of gamification on glycaemic control among patients with type 2 diabetes mellitus: a systematic review and meta-analysis of randomized controlled trials.

Aims : The prevalence of type 2 diabetes mellitus (T2DM) is very high and still rising. Optimal medical therapy and lifestyle management are essential in reducing the long-term complications of T2DM. Gamification, which is the use of design elements, and characteristics of games in a non-gaming context, is an innovative approach to improve healthy behaviour. It thereby could be able to improve glycaemic control in T2DM. The aim of this systematic review and meta-analysis is to evaluate the effect of gamification on glycaemic control expressed by haemoglobin A1c (HbA1c) levels in T2DM patients. Methods and results : All articles from 2000 to 2021 were searched in electronic databases (PubMed, Cochrane Library, Embase). The total number of patients was 704. The rate of male participants and their mean ages ranged, respectively, from 46% to 94% and 60 to 63 years. Inclusion criteria were randomized controlled trials of T2DM management using gamification which included HbA1c as an outcome measure. A meta-analysis was performed. After removing duplicates, 129 articles were screened and a total of 3 articles corresponding to the inclusion criteria were identified. Haemoglobin A1c was significantly reduced [mean difference -0.21; 95% confidence interval (-0.37 to -0.05); P = 0.01; I 2 = 0%] in the intervention group using gamification as compared to the control group. Conclusion : Gamification has a positive effect on glycaemic control expressed by HbA1c changes in patients with T2DM. However, only three studies were included in this review. More research is needed to confirm the effectiveness of gamification in T2DM.

Comparison of the Sapien 3 versus the ACURATE neo valve system: A propensity score analysis.

OBJECTIVES: To compare the outcomes of transfemoral ACURATE neo (NEO) and Sapien 3 (S3) patients in terms of device success and clinical safety outcomes using a propensity score analysis. BACKGROUND: Differences in clinical outcomes between the latest-generation balloon-expandable S3 and self-expanding NEO in a "real-world transfemoral TAVI population" are still unclear. METHODS: We compared up to 6 months clinical outcomes using a propensity score analysis (inverse probability of treatment weighting [IPTW]) to account for differences in baseline characteristics. RESULTS: A total of 345 patients underwent transfemoral transcatheter aortic valve implantation (TAVI) with either NEO or S3 at two centers in the Netherlands. Composite device success and early safety endpoints were comparable between NEO and S3 (Device success: IPTW-adjusted OR: 0.35 [95% CI: 0.12-1.18], and early safety: IPTW-adjusted OR: 0.51 [95% CI: 0.19-1.38]). Six-months mortality was 5.3 versus 3.6%, stroke was 2.8 versus 3.3%, and pacemaker rate was 6.1 versus 8.6%, respectively with p = NS. Mean aortic gradient was lower in the NEO group (5.72 ± 2.47 vs. 9.05 ± 3.48; p = <.001), with a comparable rate of moderate or severe paravalvular leak (0 versus 2.1%; p = NS). CONCLUSIONS: Device success and clinical safety outcomes were comparable for both valves. Up to 6-months follow-up clinical outcomes and mortality rate remained excellent. Mean aortic gradient was lower after ACURATE neo implantation.
