Early outcome of magnesium bioresorbable scaffold implantation in acute coronary syndrome-the initial report from the Magmaris-ACS registry

OBJECTIVES

The Magmaris-ACS Registry is the first assessment of the Magmaris implantation in the acute coronary syndrome (ACS) population.

BACKGROUND

Bioresorbable vascular scaffolds (BRS), the newest coronary stent technology, was developed to overcome the limitations of the metallic drug-eluting stents (DES). Current promising data of the Magmaris in patients with stable angina have encouraged to validate the second generation BRS in ACS indications.

METHODS

The study population consisted of the consecutive patients who underwent PCI with the Magmaris BRS in the settings of ACS. Patients with ST-segment elevation myocardial infarction were excluded from enrolment. Baseline demographic and angiographic characteristics, as well as 30-day and 6-month clinical, follow up were prospectively analyzed.

RESULTS

Fifty patients were enrolled at mean age 62.9 ± 8.4 years (unstable angina-52% and non-ST-segment myocardial infarction [NSTEMI]-48%). Treated fifty-one de novo lesions were located in LAD (37%), LCx (14%), and RCA (49%), respectively. Angiographic success in the target lesion was 100%. One case of recurrent ischemia was observed a day after the index procedure, due to the significant distal edge dissection a regular metallic DES overlapping Magmaris was implanted. No other in-hospital events occurred (procedural success 98%). Six-Month follow up showed none device-oriented endpoints such as cardiac mortality, target vessel myocardial infarction or target vessel revascularization. None early scaffold thrombosis was reported.

CONCLUSION

The use of the Magmaris BRS in non-ST elevation ACS patient is associated with a procedural safety and promising early angiographic and clinical outcomes. Long-term follow-up and further evaluation in large prospective randomized controlled trials are needed.

[Ultrasound evaluation of fetal lung maturity in imminent preterm labor cases]

The development of ultrasound examination lets us perform the biophysical assessment of fetus lungs. From 1986, at the Ivth Clinic of Obstetrics and Gynecology in Tychy, examinations of fetus lung were performed with Siemens and Bruel & Kjaer real-time ultrasonographic equipped. The elasticity of fetal lung (DLS--dynamic lung score) was estimated by taking a transversal section through the fetal chest in a plane at fetal in a plane at fetal heart and presented in 3-grade scale: I-grade--lack of elasticity (immaturity of lungs), II-grade--non complete elasticity, III-grade--normal elasticity (maturity of lungs).

Beneficial effect of short-term endurance training on glucose metabolism during rehabilitation after coronary bypass surgery

AIMS

Our study was aimed at determining whether beneficial modification of carbohydrate metabolism can be obtained after a short-term training program and whether it is associated with an increase in binding and degradation of (125)I-insulin by erythrocyte receptors that suggests a decrease in insulin resistance.

METHODS

The study was conducted in a group of 20 patients aged 56 +/- 1.9 years (mean +/- SEM), within 1 to 6 months after coronary bypass surgery. All patients completed 15 training sessions based on 30 min of cycling with a constant load. Before and after a 3-week training program, glucose, insulin, and C-peptide blood levels, as well as binding and degradation of (125)I-insulin by erythrocyte receptors, were determined.

RESULTS

A statistically significant decrease was found in the blood glucose level, from 111.2 +/- 4.2 to 97.8 +/- 3.5 mg/dL (p < 0.01); this decrease was not accompanied by significant insulin concentration changes. There was also a significant increase in insulin binding, from 0.535 +/- 0.059 to 0.668 +/- 0.042 pg (125)I/10(11) RBCs (p < 0.01), and degradation from 7.64 +/- 0.54 to 9.49 +/- 0.58 pg (125)I/10(11) RBCs (p < 0.05).

CONCLUSION

The results indicated that even short-term endurance training in patients rehabilitated after coronary bypass surgery induced favorable modification of glucose metabolism, presumably caused by a decrease in insulin resistance.

[Evaluation of endometrial thickness by transvaginal ultrasonography as a screening method in early diagnosis of endometrial cancer]

OBJECTIVES

We analyzed the usefulness of transvaginal ultrasonography in the detection of early endometrial cancer.

DESIGN

The purpose of the study was to compare histopathologic diagnosis of the curettage specimens with transvaginal ultrasound findings.

MATERIALS AND METHODS

The study included 129 women with postmenopausal bleeding scheduled for curettage. Before the curettage was performed, the thickness of the endometrium was measured using double layer technique and the thickest part was identified in the longitudinal plane.

RESULTS

In our study we didn't find endometrial hyperplasia or cancer when the endometrium was < 5 mm thick.

CONCLUSIONS

We believe that transvaginal ultrasonography in women with or without postmenopausal bleeding may be a useful method in screening for endometrial cancer as the Papanicolaou screening test for the prophylaxies of cervical cancer.

[Sonohysterography in the diagnosis of endometrial abnormalities]

OBJECTIVES

The purpose of this study was to evaluate the usefulness of sonohisterography in the diagnosis of endometrial abnormalities.

MATERIALS AND METHODS

The study included 28 pre- and postmenopausal women with abnormal vaginal bleeding scheduled for diagnostic curettage. We confronted the ultrasound findings and sonohysterography results with the histopathological diagnosis of the curettage specimens.

RESULTS

Obtained data confirmed usefulness of sonohysterography in the differential diagnosis and topography of abnormalities in the uterine cavity.

CONCLUSIONS

We believe that it's more precise to evaluate a single endometrial line using the sonohysterography technique. We can also suggest that sonohysterography may be a useful method in the early diagnosis of endometrial abnormalities and may be an alternative method for hospitals lacking hysteroscopic facilities.

[Evaluation of medical care at a delivery suite and maternity ward in the rooming-in system according to a survey of birthing mothers]

We analysed 352 opinions of the quality of medical services to delivering women, puerperants and neonates. Every opinion was willingly done and anonymous. Over 75% of women found the medical care of nurses, accoucheuses and doctors as well done. More than half of patients positively expressed their opinion on health conditions, and their stay in hospital. This survey helped us to improve our behaviour and services to a single patient.
