P2Y12 blocker monotherapy after percutaneous coronary intervention.

For secondary prevention of coronary artery disease (CAD) antiplatelet therapy is essential. For patients undergoing a percutaneous coronary intervention (PCI) temporary dual antiplatelet platelet therapy (DAPT: aspirin combined with a P2Y12 blocker) is mandatory, but leads to more bleeding than single antiplatelet therapy with aspirin. Therefore, to reduce bleeding after a PCI the duration of DAPT is usually kept as short as clinically acceptable; thereafter aspirin monotherapy is administered. Another option to reduce bleeding is to discontinue aspirin at the time of DAPT cessation and thereafter to administer P2Y12 blocker monotherapy. To date, five randomised trials have been published comparing DAPT with P2Y12 blocker monotherapy in 32,181 stented patients. Also two meta-analyses addressing this novel therapy have been presented. P2Y12 blocker monotherapy showed a 50-60% reduction in major bleeding when compared to DAPT without a significant increase in ischaemic outcomes, including stent thrombosis. This survey reviews the findings in the current literature concerning P2Y12 blocker monotherapy after PCI.

Gender differences with short-term vs 12 months dual antiplatelet therapy in patients with acute coronary syndrome treated with the COMBO dual therapy stent: 2-years follow-up results of the REDUCE trial.

BACKGROUND: Gender differences in the thrombotic and bleeding risk have been suggested to condition the benefits of antithrombotic therapies in Acute Coronary Syndrome (ACS) patients, and mainly among those undergoing percutaneous coronary interventions with drug eluting stents (DES). The impact of gender on the optimal duration of dual antiplatelet therapy (DAPT) in ACS patients is still unexplored and was, therefore, the aim of the present sub-study. METHODS: REDUCE was a prospective, multicenter, randomized investigator-initiated study designed to enroll 1500 ACS patients after treatment with the COMBO Dual Stent Therapy, based on a noninferiority design. Patients were randomized in a 1:1 fashion to either 3 or 12 months of DAPT. Primary study endpoint was a composite of all-cause mortality, myocardial infarction, definite/probable stent thrombosis (ST), stroke, target-vessel revascularization (TVR) and bleedings (BARC II, III, V) at 12 months. Secondary endpoints were cardiovascular mortality and the individual components of the primary endpoint within 24 months. RESULTS: From June 2014 to May 2016 300 women and 1196 men were included in the study. Among them, 43.7% of females and 51.9% of males were assigned to the 3 months DAPT treatment. Baseline characteristics were well matched between the two arms, with the exception of a lower rate of TIMI flow < 3 (p = 0.04), lower systolic blood pressure (p = 0.05) and use of spironolactone (p = 0.006) among women and a more advanced age (p = 0.05) among men receiving a short-term DAPT. At a mean follow-up of 525 (± 198) days, no difference in the primary endpoint was observed according to DAPT duration in both females [6.9% vs 5.9%, HR (95% CI) = 1.19 (0.48-2.9), p = 0.71] and males [8.2% vs 9%, HR (95% CI) = 0.92 (0.63-1.35), p = 0.67; p INT = 0.20]. Results were confirmed after correction for baseline differences [females: adjusted HR (95% CI) = 1.12 (0.45-2.78), p = 0.81; males: adjusted HR (95% CI) = 0.90 (0.61-1.32), p = 0.60]. Comparable rates of survival, thrombotic (MI, stent thrombosis, TVR, stroke) and bleeding events were observed with the two DAPT strategies, with no impact of gender. CONCLUSIONS: The present study shows that among ACS patients randomized in the REDUCE trial, a 3 months DAPT strategy offers comparable results as compared to a standard 12 months DAPT at 2-years follow-up in both male and female gender.

Cardiac catheterization and intervention in haemophilia patients: prospective evaluation of the 2009 institutional guideline.

Ageing haemophilia patients are increasingly confronted with ischaemic heart disease (IHD). Treatment is complex because of the delicate equilibrium between bleeding and thrombosis. In 2009, we developed an institutional guideline on how to treat IHD in this patient population. The aim of this study was to evaluate feasibility and safety of this guideline. Haemophilia patients who underwent coronary angiography or percutaneous coronary intervention between January 2009 and June 2012 were included in the current case series. Nine diagnostic or therapeutic cardiac catheterizations were performed in six haemophilia patients. One patient with moderate haemophilia B was included, whereas the other patients had mild haemophilia A. In six of nine procedures, access to the circulation was gained via the radial artery. Only bare-metal stents were implanted, after which dual antiplatelet treatment was given for at least 4 weeks. During cardiac catheterization/intervention and dual antiplatelet treatment, clotting factor levels were corrected. No thrombotic or clinically relevant bleeding complications occurred. In one patient, a low-titre inhibitor recurred 10 months after catheterization. In-stent restenosis was diagnosed in one patient. This case series indicates that treatment according to the guideline is feasible and safe. Furthermore, based on the case series and developments in new guidelines for non-haemophilic patients with IHD, some adjustments on the 2009 guideline are proposed.

Effects of video-feedback interaction training for professional caregivers of children and adults with visual and intellectual disabilities.

BACKGROUND: Individuals in group homes may experience poor quality of social interaction with their professional caregivers, limiting their quality of life. The video-based Contact programme may help caregivers to improve their interaction with clients. METHOD: Seventy-two caregivers of 12 individuals with visual and intellectual disabilities received a training programme and four individual video-feedback sessions. Quality of interaction was independently measured in an AB-design across subjects with two baseline and three intervention observations, using a time sampling coding system for interactive behaviour as well as a rating for affective mutuality. RESULTS: From baseline to intervention, significant increases were found for the frequency with which caregivers confirmed the signals of clients, for the proportion of initiatives taken by clients that were responded to by the caregivers, and the affective mutuality as a quality of the interaction. No significant increase in client responsiveness was observed. Caregivers evaluated the intervention as useful and feasible. CONCLUSIONS: The start of the Contact programme coincided with improved quality of interaction between professional caregivers and clients with visual and intellectual disabilities in group homes. Further research is necessary regarding the generalisability, long-term effects and effects on quality of life.

'People who need people': attachment and professional caregiving.

From the perspective of attachment theory, this paper discusses individual differences in the quality of caregiving by direct-care staff for persons with intellectual disabilities. Theoretical arguments and findings from related literature are cited to support the probable role of professionals' own attachment experiences and their mental representations thereof. Case examples are drawn from a study on video-based interaction guidance for direct-care staff in group homes for persons with multiple, serious disabilities. These examples illustrate how interventions may avoid attachment-related defences against changing the quality and affective mutuality of personal contact with clients. However, the possibility is discussed that in parallel processes, quality management systems and institutional culture may selectively reinforce care patterns associated with insecure, dismissing attachment, while failing to reward the positive contribution that sensitive, affectively attuned caregiving makes to wellbeing of persons with disabilities.

The effects of remifentanil and sufentanil on the quality of recovery after day case laparoscopic cholecystectomy: a randomized blinded trial.

BACKGROUND: Duration of hospitalization after laparoscopic cholecystectomy (LC) is mainly determined by temporary side effects such as pain, nausea, and vomiting. In this study we compared remifentanil, a short acting opioid, and sufentanil, a longer acting opioid, on their ability to reduce these postoperative effects and facilitate LC in day case surgery. METHOD: Seventy patients scheduled for elective LC were randomized in two groups. Remifentanil was used in group 1 as part of the anesthetic protocol, sufentanil was used in group 2. After surgery, patients were asked to evaluate pain and nausea on a verbal rate scale (VRS). Frequency of vomiting and analgesic medication consumption was registered. Time between surgery and to the start of micturition, drinking, mobilization, dressing, and discharge was recorded. Patients registered their satisfaction on a VRS. Details of any other adverse events throughout the study were recorded. RESULTS: Twenty-two patients (63%) of group 1 were treated as day cases vs. 27 (77%) in group 2 (P = NS). All patients who were not discharged as day cases left the hospital one day postoperatively. Immediately after surgery, patients in group 2 reported significantly less pain. There were no other significant differences between groups. CONCLUSION: The majority of patients scheduled for LC can be safely discharged on the day of surgery. Reported satisfaction one week postoperatively was high for all patients. We found no major relevant differences between the two anesthetic protocols.

[Necrotising pancreatitis as an unexpected complication in seriously ill patients]. / Necrotiserende pancreatitis als onverwachte complicatie bij ernstig zieke patiënten.

Three patients, two men aged 70 and 73 years, respectively, who underwent surgery due to an abdominal aortic aneurysm, and a woman aged 75 years, who was operated on due to acute arterial embolic occlusion of both legs, developed abdominal complaints post-operatively. These were found to be caused by necrotising pancreatitis. The accompanying fluid accumulation was drained percutaneously. Two patients recovered; the 73-year-old man died suddenly, possibly as a result of burst aortic sutures. In patients with a serious condition, necrotising pancreatitis should be considered in the case of a generalised inflammatory reaction and abdominal symptoms. Percutaneous drainage of infected necrotic tissue can sometimes improve the patient's condition, making surgery possible at a later stage.

Hemodynamic changes with right lateral decubitus body positioning in the tilted porcine heart.

BACKGROUND: In beating-heart coronary surgical procedures, exposure of posterior vessels through sternotomy causes cardiac function to deteriorate. We hypothesized that turning the subject to the right lateral decubitus position before cardiac retraction improves exposure of posterior vessels and preserves cardiac pump function on displacement. METHODS: Eight 80-kg open-chest pigs were instrumented with catheter-tip manometers. After a stepwise 60-degree turn to the right lateral decubitus position of the body, the heart was retracted anteriorly to 90 degrees with a suction stabilizer. RESULTS: Right lateral body positioning caused an approximately 45-degree right deviation of the apex, thereby exposing the left atrial groove. Stroke volume, mean arterial pressure, right atrial pressure, and right ventricular end-diastolic pressure increased to 106% +/- 5% (mean +/- standard error of the mean, p = 0.31), 106% +/- 3% (p = 0.01), 129% +/- 8% (p = 0.001), and 171% +/- 14% (p = 0.002), respectively, compared with control values. In contrast, left atrial pressure decreased to 73% +/- 6% (p = 0.007), whereas left ventricular preload remained unchanged (110% +/- 8%, p = 0.26). Additional anterior displacement to 90 degrees fully exposed the posterior vessels, and stroke volume decreased to 90% +/- 3% (p = 0.01) and mean arterial pressure to 93% +/- 5% (p = 0.07) at the expense of further increased right ventricular preload (256% +/- 28%, p < 0.001). CONCLUSIONS: By placing the subject in the right lateral decubitus position, exposure through sternotomy of posterior vessels in the beating porcine heart was facilitated while mean arterial pressure was maintained.
