Management of Pregnant Inflammatory Bowel Disease Patients During the COVID-19 Pandemic.

The rapid emergence of the novel coronavirus [SARS-CoV2] and the coronavirus disease 2019 [COVID-19] has caused significant global morbidity and mortality. This is particularly concerning for vulnerable groups such as pregnant women with inflammatory bowel disease [IBD]. Care for pregnant IBD patients in itself is a complex issue because of the delicate balance between controlling maternal IBD as well as promoting the health of the unborn child. This often requires continued immunosuppressive maintenance medication or the introduction of new IBD medication during pregnancy. The current global COVID-19 pandemic creates an additional challenge in the management of pregnant IBD patients. In this paper we aimed to answer relevant questions that can be encountered in daily clinical practice when caring for pregnant women with IBD during the current COVID-19 pandemic.

Effectiveness of perindopril/amlodipine fixed dose combination in everyday clinical practice: results from the EMERALD study.

OBJECTIVE: The rates of blood pressure (BP) control worldwide are discouraging. This study had the purpose of assessing the effectiveness of perindopril/amlodipine fixed dose combination on BP-lowering efficacy, and recording adherence, safety and tolerability during a 4 month treatment period. RESEARCH DESIGN AND METHODS: In this multicenter, observational study 2269 hypertensive patients were prospectively enrolled. The data were recorded at 1 and 4 months of treatment. MAIN OUTCOME MEASURES AND RESULTS: Between the first and third visits mean BP values (systolic/diastolic) decreased from 158.4 ± 13.6/89.9 ± 8.7 mmHg to 130.0 ± 7.9/77.7 ± 6.3 mmHg (P < 0.001). The magnitude of BP reduction depended on baseline blood pressure levels and total cardiovascular (CV) risk (P < 0.001). Patients with grade 1, 2 and 3 showed a BP reduction of 21.9/10.0 mmHg, 34.4/14.2 mmHg and 51.4/21.2 mmHg, accordingly (P < 0.001). Patients with very high, high, moderate and low added CV risk showed a BP reduction of 35.7/14.9 mmHg, 27.5/12.1 mmHg, 28.6/12.2 mmHg and 14.5/5.8 mmHg respectively (P < 0.001). Adherence to treatment was high: 98.3% of the sample was taking the treatment "every day" or "quite often", while only 15 patients (0.7% of the sample) prematurely discontinued treatment. Study interpretation may be limited by the fact that this is an observational study with no comparator and a short follow-up period. CONCLUSIONS: A perindopril/amlodipine fixed dose combination significantly decreases BP levels. The degree of BP reduction is related to baseline BP levels and total CV risk.

A comparison study of brachial blood pressure recorded with Spacelabs 90217A and Mobil-O-Graph NG devices under static and ambulatory conditions.

Ambulatory blood pressure monitoring is an important tool in hypertension diagnosis and management. Although several ambulatory devices exist, comparative studies are scarce. This study aimed to compare for the first time brachial blood pressure levels of Spacelabs 90217A and Mobil-O-Graph NG, under static and ambulatory conditions. We examined 40 healthy individuals under static (study A) and ambulatory (study B) conditions. In study A, participants were randomized into two groups that included blood pressure measurements with mercury sphygmomanometer, Spacelabs and Mobil-O-Graph devices with reverse order of recordings. In study B, simultaneous 6-h recordings with both devices were performed with participants randomized in two sequences of device positioning with arm reversal at 3 h. Finally, all the participants filled in a questionnaire rating their overall preference for a device. In study A, brachial systolic blood pressure (117.2±10.3 vs 117.1±9.8 mm Hg, P=0.943) and diastolic blood pressure (73.3±9.4 mm Hg vs 74.1±9.4 mm Hg, P=0.611) did not differ between Spacelabs and Mobil-O-Graph or vs sphygmomanometer (117.8±11.1 mm Hg, P=0.791 vs Spacelabs, P=0.753 vs Mobil-O-Graph). Similarly, no differences were found in ambulatory systolic blood pressure (117.9±11.4 vs 118.3±11.0 mm Hg, P=0.864), diastolic blood pressure (73.7±7.4 vs 74.7±8.0 mm Hg, P=0.571), mean blood pressure and heart rate between Spacelabs and Mobil-O-Graph. Correlation analyses and Bland-Altman plots showed agreement between the monitors. Overall, the participants showed a preference for the Mobil-O-Graph. Spacelabs 90217A and Mobil-O-Graph NG provide practically identical measurements during the static and ambulatory conditions in healthy individuals and can be rather used interchangeably in clinical practice.

Epidemiology and outcome of elderly admitted to the ward for sepsis.

BACKGROUND: The elderly represent a significant cohort of patients presenting at the emergency department, especially in the developed countries. They are characterized by impaired physical condition, comorbidities, and little immune system resources and make frequent use of the healthcare system and its facilities. This study aimed to describe the features and prognostic factors of sepsis in elderly patients (>60 years old) admitted to an internal medicine ward. MATERIAL AND METHODS: Two hundred eighty eight consecutively patients aged >60 years who were admitted with sepsis during a two-year-period were retrospectively included in the study. Clinical and laboratory parameters at presentation were analyzed. Causes of sepsis and biochemical markers were compared between the healthcare facility-naïve and the healthcare facility-exposed groups. The effect of comorbidities and previous exposure to the healthcare system on clinical course and outcome of the patients was analyzed. RESULTS: Among the comorbidities that were recorded and included in the analysis, the presence of chronic and acute renal impairment and neurologic disabilities were associated with a worse outcome of sepsis in the elderly. In the same cohort, a previous contact with the healthcare system was found to affect the duration of hospital stay, but not the outcome per se. Sepsis-related markers, such as inflammatory markers were not found to be associated with clinical progression and outcome. CONCLUSIONS: Timely diagnosis and accurate evaluation of the severity of sepsis is required to ensure a better outcome for the patients. Sensitive markers and accurate prognostic models are constantly pursued. The impact of living characteristics of the modern aging society is additionally addressed and their effect on sepsis outcome assessed. Hippokratia 2016, 20(4): 274-278.

The safety and efficacy of irreversible electroporation for the ablation of prostate cancer: a multicentre prospective human in vivo pilot study protocol.

INTRODUCTION: Current surgical and ablative treatment options for prostate cancer have a relatively high incidence of side effects, which may diminish the quality of life. The side effects are a consequence of procedure-related damage of the blood vessels, bowel, urethra or neurovascular bundle. Ablation with irreversible electroporation (IRE) has shown to be effective in destroying tumour cells and harbours the advantage of sparing surrounding tissue and vital structures. The aim of the study is to evaluate the safety and efficacy and to acquire data on patient experience of minimally invasive, transperineally image-guided IRE for the focal ablation of prostate cancer. METHODS AND ANALYSIS: In this multicentre pilot study, 16 patients with prostate cancer who are scheduled for a radical prostatectomy will undergo an IRE procedure, approximately 30 days prior to the radical prostatectomy. Data as adverse events, side effects, functional outcomes, pain and quality of life will be collected and patients will be controlled at 1 and 2 weeks post-IRE, 1 day preprostatectomy and postprostatectomy. Prior to the IRE procedure and the radical prostatectomy, all patients will undergo a multiparametric MRI and contrast-enhanced ultrasound of the prostate. The efficacy of ablation will be determined by whole mount histopathological examination, which will be correlated with the imaging of the ablation zone. ETHICS AND DISSEMINATION: The protocol is approved by the ethics committee at the coordinating centre (Academic Medical Center (AMC) Amsterdam) and by the local Institutional Review Board at the participating centres. Data will be presented at international conferences and published in peer-reviewed journals. CONCLUSIONS: This pilot study will determine the safety and efficacy of IRE in the prostate. It will show the radiological and histopathological effects of IRE ablations and it will provide data to construct an accurate treatment planning tool for IRE in prostate tissue. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov database: NCT01790451.

High-density lipoprotein, vascular risk, cancer and infection: a case of quantity and quality?

Low levels of high-density lipoprotein cholesterol (HDL-C) have been associated with increased cardiovascular (CV) risk. These beneficial effects of HDL can be, at least partly, attributed to its anti-inflammatory, antithrombotic, antioxidant and endothelial-protective properties. However, the results of some clinical trials aiming at raising HDL-C levels are conflicting in terms of CV protection suggesting that alterations in HDL quality (and not only quantity) are involved in the atherosclerotic process. In this context, inflammation, oxidation, infection, hyperglycemia and activated platelets may modify HDL components, thus transforming HDL to a dysfunctional molecule with pro-atherogenic properties. Furthermore, some recent trials with HDL-raising drugs, such as niacin and torcetrapib, reported a lack of benefit in terms of vascular risk as well as adverse events including cancer and infections. In this narrative review, the findings of recent HDL clinical studies in relation to CV events as well as the associations of HDL with cancer and infections are discussed. The possible pathogenic mechanisms of these associations are also considered. The clinical implications of HDL function in treating patients at high CV risk remains to be established in future trials.

The clinical utility of bone turnover markers in the evaluation of bone disease in patients with haemophilia A and B.

Haemophilia A and B have been associated with increased prevalence of low bone mineral density (BMD). However, the utility of bone turnover markers (BTM) remains unknown. The aim of this study was to evaluate bone metabolism in men with haemophilia and to investigate associations between BTM and bone disease. Serum N- (NTX-I), C-terminal telopeptide of type I collagen (CTX-I) and tartrate-resistant acid phosphatase band-5b (TRAP-5b), as bone resorption markers, and osteocalcin (OC) and bone-specific alkaline phosphatase (b-ALP), as bone formation markers, were assessed. Seventy men with haemophilia A (n = 59) or B (n = 11) were studied. Patients with low BMD had significantly higher b-ALP concentrations compared with those with normal BMD (12.8 ± 1.60 vs. 9.72 ± 0.58 µg/L, P = 0.009), without any differences in the other BTM. NTX-I and CTX-I concentrations were negatively associated with oestradiol levels and hip BMD and positively with human immunodeficiency virus infection, number of affected joints and arthropathy scores. B-ALP and OC concentrations were negatively associated with hip BMD, severity of haemophilia and fracture history, and positively with the number of affected joints and testosterone concentrations. After multivariate analysis, NTX-I levels remained negatively associated with oestradiol levels, whereas b-ALP concentrations negatively correlated with the level of physical activity and positively with the number of affected joints. Increased bone metabolism exists in men with haemophilia and low BMD. Increased b-ALP levels may identify patients at high risk for fracture. Increased number of target joints, low physical activity and low oestradiol concentrations are independently associated with increased bone metabolism.

Simple variables predict miserable outcome after intravenous thrombolysis.

BACKGROUND AND PURPOSE: To test the predictability of miserable outcome amongst ischaemic stroke patients receiving intravenous thrombolysis (IVT) based on a simple variables model (SVM) and to compare the model's predictive performance with that of an existing score which includes imaging and laboratory parameters (DRAGON). METHODS: The SVM consists of the parameters age, independence before stroke, normal Glasgow coma verbal score, able to lift arms and able to walk. In a derivation cohort (n = 1346) and a validation cohort (n = 638) of consecutive IVT-treated stroke patients, the probability estimated by SVM and the observed occurrence of miserable 3-month outcome (modified Rankin score 5-6) were compared. The performances of SVM and the DRAGON score were compared. The area under the receiver operating curve (AUC) (95% confidence interval, CI) and the bootstrapping approach were used to compare the predictive performance. RESULTS: The AUCs to predict miserable outcome in the derivation cohort were 0.807 (95% CI 0.774-0.838) using the SVM and 0.822 (0.790-0.850) using the DRAGON score (P = 0.3). For the validation cohort, AUCs were 0.786 (0.742-0.829) for the SVM and 0.809 (0.774-0.845) for the DRAGON score (P = 0.23). Only one patient with an SVM probability of >70% for miserable outcome in either cohort had a good outcome whilst 83% had a miserable outcome. An online SVM calculator to estimate the probability of miserable outcome for individual patients is available under http://www.unispital-basel.ch/SVM-Tool. CONCLUSION: The SVM was similar in accuracy to the DRAGON score for predicting miserable outcome after IVT. As these simple variables are available already at the pre-hospital stage, the SVM may facilitate and accelerate pre-hospital triage of patients at high risk for miserable outcome after IVT towards endovascular treatment.

Diabetes, bilirubin and amputations: is there a link?

A study by Chan et al in this issue of Diabetologia (DOI: 10.1007/s00125-012-2818-4 ) reports that low plasma bilirubin levels are associated with an increased risk of amputation in patients with type 2 diabetes mellitus participating in the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study. These findings raise the interesting and clinically relevant hypothesis that bilirubin protects against risk of amputation in patients with type 2 diabetes. This commentary considers some of the limitations associated with research aiming to define any link between circulating bilirubin levels and vascular disease. Numerous confounding factors (several of which may be present in patients with type 2 diabetes) may explain why the literature regarding this potentially protective role of bilirubin remains controversial.

Comparative effects of rosuvastatin and atorvastatin on glucose metabolism and adipokine levels in non-diabetic patients with dyslipidaemia: a prospective randomised open-label study.

AIMS: The impact of statins on glucose metabolism and adipokines remains controversial. We compared the effects of rosuvastatin and atorvastatin on glucose homeostasis, insulin sensitivity (IS), adiponectin and leptin levels as well as systemic inflammation in non-diabetic patients with dyslipidaemia. METHODS: Thirty-six patients were randomly assigned to 10 mg/day of rosuvastatin (n = 18) or 20 mg/day of atorvastatin (n = 18) for 12 weeks. Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, triglycerides (TG), fasting plasma glucose, insulin, homeostasis model assessment-insulin resistance (HOMA-IR), quantitative IS check index (QUICKI), adiponectin, leptin and high-sensitivity C-reactive protein (hsCRP) were measured at baseline and after 4 and 12 weeks. RESULTS: Both statins significantly lowered TC, LDL-C, non-HDL-C and TG compared with baseline. Only rosuvastatin caused a significant reduction in insulin and HOMA-IR levels (-35%, p = 0.005 and -33%, p = 0.011 respectively) and a significant increase in QUICKI (+11%, p = 0.003) at 12 weeks. In terms of adipokines and hsCRP, no difference was observed after 4 and 12 weeks of treatment with either statin. CONCLUSIONS: Rosuvastatin compared with atorvastatin resulted in significant improvements in IS indices. No significant changes in adiponectin, leptin or hsCRP levels were observed at 4 and 12 weeks of treatment with either statin.

Cardiovascular benefits of bariatric surgery in morbidly obese patients.

Morbid obesity is associated with increased morbidity and represents a major healthcare problem with increasing incidence worldwide. Bariatric surgery is considered an effective option for the management of morbid obesity. We searched MEDLINE, Current Contents and the Cochrane Library for papers published on bariatric surgery in English from 1 January 1990 to 20 July 2010. We also manually checked the references of retrieved articles for any pertinent material. Bariatric surgery results in resolution of major comorbidities including type 2 diabetes mellitus, hypertension, dyslipidemia, metabolic syndrome, non-alcoholic fatty liver disease, nephropathy, left ventricular hypertrophy and obstructive sleep apnea in the majority of morbidly obese patients. Through these effects and possibly other independent mechanisms bariatric surgery appears to reduce cardiovascular morbidity and mortality. Laparoscopic Roux-en-Y gastric bypass (LRYGB) appears to be more effective than laparoscopic adjustable gastric banding (LAGB) in terms of weight loss and resolution of comorbidities. Operation-associated mortality rates after bariatric surgery are low and LAGB is safer than LRYGB. In morbidly obese patients bariatric surgery is safe and appears to reduce cardiovascular morbidity and mortality.

Glucagon-like peptide-1-based therapies and cardiovascular disease: looking beyond glycaemic control.

Type 2 diabetes mellitus is a well-established risk factor for cardiovascular disease (CVD). New therapeutic approaches have been developed recently based on the incretin phenomenon, such as the degradation-resistant incretin mimetic exenatide and the glucagon-like peptide-1 (GLP-1) analogue liraglutide, as well as the dipeptidyl dipeptidase (DPP)-4 inhibitors, such as sitagliptin, vildagliptin, saxagliptin, which increase the circulating bioactive GLP-1. GLP-1 exerts its glucose-regulatory action via stimulation of insulin secretion and glucagon suppression by a glucose-dependent way, as well as by weight loss via inhibition of gastric emptying and reduction of appetite and food intake. These actions are mediated through GLP-1 receptors (GLP-1Rs), although GLP-1R-independent pathways have been reported. Except for the pancreatic islets, GLP-1Rs are also present in several other tissues including central and peripheral nervous systems, gastrointestinal tract, heart and vasculature, suggesting a pleiotropic activity of GLP-1. Indeed, accumulating data from both animal and human studies suggest a beneficial effect of GLP-1 and its metabolites on myocardium, endothelium and vasculature, as well as potential anti-inflammatory and antiatherogenic actions. Growing lines of evidence have also confirmed these actions for exenatide and to a lesser extent for liraglutide and DPP-4 inhibitors compared with placebo or standard diabetes therapies. This suggests a potential cardioprotective effect beyond glucose control and weight loss. Whether these agents actually decrease CVD outcomes remains to be confirmed by large randomized placebo-controlled trials. This review discusses the role of GLP-1 on the cardiovascular system and addresses the impact of GLP-1-based therapies on CVD outcomes.

Effect of a plant stanol ester-containing spread, placebo spread, or Mediterranean diet on estimated cardiovascular risk and lipid, inflammatory and haemostatic factors.

BACKGROUND AND AIMS: Mediterranean diet is associated with a reduced risk for cardiovascular disease (CVD). Use of plant stanols decreases low density lipoprotein cholesterol (LDL-C) concentrations. We compared the effects of the Mediterranean diet and plant stanol esters on vascular risk factors and estimated CVD (eCVD) risk. METHODS AND RESULTS: In this prospective, randomized, placebo-controlled study, 150 mildly hypercholesterolaemic subjects were randomized to Mediterranean diet, a spread containing plant stanol esters (2 g/day) or a placebo spread. Vascular risk factors were assessed every month for 4 months and the eCVD risk was calculated using the PROspective- Cardiovascular-Munster (PROCAM), Framingham, and Reynolds risk engines. Placebo had no significant effect on risk factors or eCVD risk. Mediterranean diet gradually induced a significant reduction in total cholesterol (TC), LDL-C, triglycerides, high sensitivity C-reactive protein (hsCRP), blood pressure and eCVD risk (24-32%). The plant stanol ester spread reduced (by 1 month) TC (-14%), LDL-C (-16%), hsCRP (-17%), and estimated CVD risk (26-30%). eCVD risk reduction was sustained at 4th months when the gradual Mediterranean diet eCVD risk reduction became comparable to that of the stanol group. CONCLUSIONS: Plant stanol esters yielded an early, by 1st treatment month, reduction of eCVD risk that resulted from a TC, LDL-C, and hsCRP decrease. eCVD risk reduction on the Mediterranean diet resulted from a change in several CVD risk factors and equaled that of plant stanol at 4 months. The consumption of plant stanol esters by moderately hypercholesterolaemic patients may be a useful option to reduce CVD risk in those who do not adopt a Mediterranean diet.

Brain natriuretic peptide and the athlete's heart: a pilot study.

BACKGROUND: The role of brain natriuretic peptide (BNP) in differentiating the athlete's heart from maladaptive cardiac hypertrophy is unclear. METHODS: To address this issue, an integrated M mode, two-dimensional B mode and Doppler echocardiographical study were performed and plasma BNP levels were measured in 25 strength athletes, 25 patients with established hypertrophic cardiomyopathy (HCM) and 25 healthy volunteers. RESULTS: Among athletes, BNP levels correlated negatively with the total training time (r = -0.79, p = 0.002) and positively with ejection fraction (r = 0.58, p = 0.049) and fractional shortening (r = 0.57, p = 0.049). A BNP cut-off value of 11.8 pg/ml had 88% specificity and 74% negative predictive value for the exclusion of HCM. CONCLUSIONS: Brain natriuretic peptide might be useful as a preparticipation screening test in athletes.

Implementation of responsible care in the chemical industry: evidence from Greece.

The chemical industry can be held accountable for numerous large-scale accidents which have led to the release of dangerous hazardous materials, pollutants and toxic chemicals into the environment, two well-known examples being the Union Carbide Bhopal disaster and the Three Mile Island tragedy). To ensure environmental protection and the Health and Safety (H&S) of communities, the chemical industry has voluntarily adopted integrated management programs such as the Responsible Care Program. The theoretical body of relevant literature attempts to explain the origin of the Responsible Care Program (RCP) through socio-political and economic theories. At the same time, the empirical research examines the ways in which various factors affect the choice of the chemical industry in their adoption of the RCP. This paper contributes to the debate by examining the challenges and barriers faced by the Greek chemical industry when adopting RCP, the environmental and H&S issues that prevail and finally, the extent of participation of stakeholders in the planning of RCP in the sector.

Endothelial dysfunction in metabolic syndrome: prevalence, pathogenesis and management.

The metabolic syndrome (MetS) is characterized by the presence of central obesity, impaired glucose metabolism, dyslipidemia and hypertension. Several studies showed that MetS is associated with increased risk for type 2 diabetes mellitus (T2DM) and vascular events. All components of MetS have adverse effects on the endothelium. Endothelial dysfunction plays a role in the pathogenesis of atherosclerosis and might also increase the risk for insulin resistance and T2DM. We review the prevalence and pathogenesis of endothelial dysfunction in MetS. We also discuss the potential effects of lifestyle measures and pharmacological interventions on endothelial function in these patients. It remains to be established whether improving endothelial function in MetS will reduce the risk for T2DM and vascular events.
