RESUMEN

STUDY QUESTION: Does platelet-rich plasma (PRP) intraovarian injection increase the number of retrieved oocytes in successive ovarian punctions among patients with poor ovarian reserve (POR)? SUMMARY ANSWER: The injection of PRP increases the number of retrieved oocytes without increasing the quality of developed blastocysts. WHAT IS KNOWN ALREADY: Management of women with reduced ovarian response to stimulation is one of the significant challenges in reproductive medicine. Recently, PRP treatment has been proposed as an adjunct in assisted reproduction technology, with controversial results. STUDY DESIGN, SIZE, DURATION: This placebo-controlled, double-blind, randomized trial included 60 patients with POR stratified according to the POSEIDON classification groups 3 and 4. It was conducted to explore the efficacy and safety of intraovarian PRP injection. Patients were proposed to undergo three consecutive ovarian stimulations to accumulate oocytes and were randomized to receive either PRP or placebo during their first oocyte retrieval. Randomization was performed using computer-generated randomization codes. Double blinding was ensured so that neither the participant nor the investigators knew of the treatment allotted. All patients underwent three ovarian stimulations and egg retrieval procedures. ICSI was performed after a third ovarian puncture. The primary endpoint was the number of mature oocytes retrieved after PRP or placebo injection in successive ovarian punctures. PARTICIPANTS/MATERIALS, SETTING, METHODS: Sixty women (30-42 years) fulfilling inclusion criteria were randomized in equal proportions to the treatment or control groups. MAIN RESULTS AND THE ROLE OF CHANCE: The baseline demographic and clinical characteristics [age, BMI, anti-Müllerian hormone (AMH) levels] were comparable between the groups. Regarding the primary endpoint, the cumulative number (mean ± SEM) of retrieved mature oocytes was slightly higher in the treatment group: 10.45 ± 0.41 versus 8.91 ± 0.39 in the control group, respectively (95% CI of the difference 0.42-2.66; P = 0,008). The number of mature oocytes obtained among all patients increased in successive egg retrievals: 2.61 ± 0.33 (mean ± SEM) in punction 1 (P1), 3.85 ± 0.42 in P2, and 4.73 ± 0.44 in P3. However, the increase was higher among patients receiving the assessed PRP treatment. In P2, the number of retrieved mature oocytes was 4.18 ± 0.58 versus 3.27 ± 0.61 in controls (95% CI of the difference: -0.30 to 2.12; P = 0.138) and in P3, 5.27 ± 0.73 versus 4.15 ± 0.45 (95% CI of the difference: 0.12-2.12; P = 0.029). The mean ± SEM number of developed and biopsied blastocysts was 2.43 ± 0.60 in the control group and 1.90 ± 0.32 in the treatment group, respectively (P = 0.449). The mean number of euploid blastocysts was 0.81 ± 0.24 and 0.81 ± 0.25 in the control and treatment groups, respectively (P = 1.000). The percentages of patients with euploid blastocysts were 53.33% (16 out of 30) and 43.33% (13 out of 30) for patients in the control and treatment groups, respectively (Fisher's exact test P = 0.606). The overall pregnancy rate per ITT was 43% (26 out of 60 patients). However, the percentage of clinical pregnancies was higher in the control group (18 out of 30, 60%) than in the treatment group (8 out of 30, 27%) (P = 0.018). There was also a trend toward poorer outcomes in the treatment group when considering full-term pregnancies (P = 0.170). There were no differences between control and treatment groups regarding type of delivery, and sex of newborns. LIMITATIONS, REASONS FOR CAUTION: The mechanism of the potential beneficial effect of PRP injection on the number of retrieved oocytes is unknown. Either delivered platelet factors or a mechanical effect could be implicated. Further studies will be needed to confirm or refute the data presented in this trial and to specify the exact mechanism of action, if any, of PRP preparations. WIDER IMPLICATIONS OF THE FINDINGS: The increasing number of women with a poor response to ovarian stimulation supports the exploration of new areas of research to know the potential benefits of therapies capable of increasing the number of oocytes available for fertilization and improving the quality of developed blastocysts. An increase in the retrieved oocytes in both arms of the trial suggests that, beyond the release of growth factor from platelets, a mechanical effect can play a role. However, neither improvement in euploid blastocyst development nor pregnancy rates have been demonstrated.

RESUMEN

OBJECTIVE: To ascertain the predictive value of different parameters to determine endometrial receptivity among assisted reproduction treatments in which single embryo transfer of frozen-thawed euploid blastocysts are performed. STUDY DESIGN: Observational study involving 104 patients recruited between September.2018 and June.2019 at a University associated assisted reproduction center. The relationship of different parameters (age, body mass index (BMI), duration of hormonal preparation, plasmatic progesterone levels, endometrial parameters at ultrasound assessment and endometrial receptivity determined by endometrial receptivity assay (ERA) was evaluated by a multivariable logistic (binomial) analysis after hormonal preparation. According to the ERA test results a personalized endometrial transfer (pET) was scheduled and live birth rate was assessed. Only single transfers of frozen euploid blastocysts were performed. RESULTS: ERA test report predicted receptive endometrium (RE) in 54,64% patients and non-receptive (NR) in 45,31% patients. Among NR endometrial samples, 20,62% were classified as pre-receptive or early receptive, whereas 24,74% as post-receptive or late-receptive. The univariate analysis showed a relationship between BMI, doses of progesterone administered before biopsy and the receptivity of endometrium. There was no relationship between age of women, duration of hormonal supplementation, and the results of ERA test. In our series, endometrial receptivity was not related neither to endometrial thickness nor plasmatic progesterone levels. The multivariate analysis showed that both, BMI and cumulative progesterone administered prior to the test are independent predictive factors of endometrial receptivity (p = 0,047 and p = 0,034 respectively). The overall live birth rate after FET of euploid embryos was 62,35%. The odd of pregnancy was higher when ERA test was performed prior to the first embryo transfer (93,10% vs. 46,43%; OR = 15,58;95%CI 3,38-71,89). Overall, ongoing pregnancy rates showed a favorable trend after "non-receptive" endometria had been diagnosed and, thus, a modified (pET) preparation was performed (70,00% vs. 55,56%; OR = 1,87; 95% CI 0,76-4,57). CONCLUSION: Regarding implantation potential of genetically screened blastocysts, the traditional tools used for assessing endometrial receptivity such as transvaginal evaluation of endometrial thickness and pattern or progesterone levels determination were not useful among our patients for predicting a receptive endometrium.

RESUMEN

BACKGROUND: To investigate the value of a single determination of hyperglycosylated hCG (hCG-H) for predicting the clinical outcome of patients with threatened abortion in the first trimester of pregnancy. METHODS: Prospective study performed on 86 consecutively selected women with a diagnosis of threatened abortion and viable intrauterine pregnancy in the first trimester of pregnancy, conducted in two tertiary care hospitals. All patients underwent a single blood sample to determine hCG-H and total hCG serum levels and a transvaginal ultrasound 12-24 hours after diagnosis. Patients were monitored to determine whether the outcome was a miscarriage before the 20th week of pregnancy. RESULTS: Forty-three women (50%) had a miscarriage during the follow-up. We observed a very high correlation between hCG-H and total hCG (r?=?0.91, p?

RESUMEN

BACKGROUND: To investigate the value of a single determination of hyperglycosylated hCG (hCG-H) for predicting the clinical outcome of patients with threatened abortion in the first trimester of pregnancy. METHODS: Prospective study performed on 86 consecutively selected women with a diagnosis of threatened abortion and viable intrauterine pregnancy in the first trimester of pregnancy, conducted in two tertiary care hospitals. All patients underwent a single blood sample to determine hCG-H and total hCG serum levels and a transvaginal ultra-sound 12-24 hours after diagnosis. Patients were monitored to determine whether the outcome was a miscarriage before the 20th week of pregnancy. RESULTS: Forty-three women (50%) had a miscarriage during the follow-up. We observed a very high correlation between hCG-H and total hCG (r = 0.91, p < 0.001). Median hCG-H and total hCG from pregnancies with normal outcome was significantly higher than those ending in abortion. hCG-H and total hCG were very similar predictors of pregnancy outcomes (AUC: 0.90 and 0.89, respectively). The ratio hCG-H / total hCG was a poor predictor (AUC: 0.64). CONCLUSION: A single hCG-H assay is helpful for predicting pregnancy outcomes in women with first trimester threatened abortion and viable or potentially viable pregnancy at the time of presentation. However, hCG-H is not a better predictor than total hCG


FUNDAMENTO: Investigar el valor de una única determinación de hCG hiperglicosilada (hCG-H) para predecir el resultado clínico de pacientes con amenaza de aborto en el primer trimestre del embarazo. MÉTODOS: Estudio prospectivo realizado en 86 mujeres, seleccionadas consecutivamente, con diagnóstico de amenaza de aborto y embarazo intrauterino viable en el primer trimestre de embarazo, realizado en dos hospitales de tercer nivel. A todas las pacientes se les realizó una única extracción sanguínea para determinar los niveles séricos de hCG-H y hCG total, y una ecografía transvaginal 12-24 horas después del episodio de sangrado. Se realizó seguimiento de las pacientes para determinar si el resultado fue un aborto espontáneo antes de la semana 20 de embarazo. RESULTADOS: Cuarenta y tres mujeres (50%) sufrieron un aborto espontáneo durante el seguimiento. Se observó una correlación muy alta entre hCG-H y hCG total (r = 0,91, p < 0,001). La mediana de hCG-H y hCG total de los embarazos con resultado normal fue significativamente mayor que la de aquellos que terminaron en aborto. La hCG-H y la hCG total fueron predictores muy similares del resultado del embarazo (AUC: 0,90 y 0,89, respectivamente). La relación hCG-H / hCG total fue un mal predictor (AUC: 0,64). CONCLUSIÓN: La determinación única de hCG-H es útil para predecir el resultado del embarazo en mujeres con amenaza de aborto en el primer trimestre y embarazo viable en el momento de la presentación clínica. Sin embargo, la hCG-H no es mejor predictor que la hCG total

RESUMEN

AIMS: To evaluate the cardiac mortality in patients suffering from a first episode of sustained monomorphic ventricular tachycardia (SMVT). METHODS: 100 patients less than 75 years old were evaluated during a 50-month follow-up period. Patients were classified into four groups: myocardial infarction, dilated cardiomyopathy, normal heart and miscellany. Seventeen patients underwent a cardioverter-defibrillator implantation, two heart transplant, three aneurysmectomy and 10 other types of cardiac surgical proceedings. RESULTS: Patients with a left ventricle ejection fraction (EF)> or =50% presented a cardiac mortality of 5% compared with 38% of those with EF<50%. Etiology of underlying cardiomyopathy with an EF> or =50% was associated with a cardiac mortality of 5% (normal heart), 5% (myocardial infarction) and 9% (miscellany) compared to those with EF<50%: 33% (dilated cardiomyopathy) and 40% (myocardial infarction). Patients who experienced syncope during the first episode of SMVT showed a cardiac mortality of 31% compared to those 14% (P < 0.05) who did not experience. Patients with syncope, myocardial infarction and EF<50% showed a cardiac mortality of 68%. CONCLUSION: The present study shows that survival after the first episode of SMVT is closely related to EF and the existence of syncope. Patients with myocardial infarction and EF<50% had a worse prognosis when the site was the inferior wall.

RESUMEN

INTRODUCTION AND OBJECTIVES: Since 1989, the balloon expandable Palmaz stent (Johnson & Johnson Interventional Systems) has been used for the treatment of congenital heart disease. This study reports the results and the technique used for its implantation in native and post surgical retraction pulmonary branch stenosis. MATERIALS AND METHODS: From february 1995 to june 1996, we have performed this technique in 11 symptomatic children/adolescents with pulmonary branch stenosis, the mean age was 11 +/- 2 years. Fourteen procedures were made and 16 stents were implanted. The mean condition of the patients was: 7 with tetralogy of Fallot after a previous complete correction, 1 with Noonan syndrome and a surgically corrected atrial septal defect, 1 with pulmonary trunk aneurysm and a previous surgical correction for pulmonary valve and branch stenosis, 1 with pulmonary atresia and an intact septum who underwent a surgical valvotomy and posterior percutaneous valvuloplasty with a good ventricular development, and final was a tricuspid atresia with a previous Waterston anastomosis which produced a stenosis at the right pulmonary branch who underwent a modified Fontan operation with the result of a severe stenosis at the medial and inferior right pulmonary artery. The branch ostium was affected in five cases, and in one case with diffuse hypoplasia of the right branch, the stenosis was at both sites. The stenosis was native in nine cases and post surgery in the other five (2 Waterston, 1 Blalock-Taussig, 1 Fontan). We used the right and/or left femoral vein in all cases except two, in which we used the internal jugular vein. We followed the technique reported by the Boston-Houston experience, with an extra stiff guide and Mullins sheath towards the site of the stenosis. RESULTS: The procedure was effective in all cases except one. The mean pulmonary branch and balloon diameter was 11 +/- 3 mm and 14 +/- 2 mm, respectively, rate 1.2. The stenosis diameter rose from 4.8 +/- 1 to 11 +/- 2 mm (p < 0.001) with a percentage fall from 63 +/- 5 to 2 +/- 1% (p < 0.001). The pressure gradient fell from 30 +/- 5 to 5 +/- 1 mmHg (p < 0.001) and the right ventricle systolic pressure fell from 77 +/- 6 to 48 +/- 3 mmHg (p < 0.01). The mean followup was 10 +/- 3 months, a symptomatic and pulmonary perfusion improvement was seen. After 8 +/- 4 months, we evaluated six patients/nine stents with angiography, and we excluded thrombosis, aneurysms and occlusion of lobar or segmental branches. One case had a proximal stent re-stenosis as it did not cover the whole stenosis, so a new stent was implanted. Three patients/four stents underwent redilatation getting a slightly higher diameter than previously. COMPLICATIONS: One patient had a stent migration and he underwent surgical stent retrieval. CONCLUSIONS: Implantation of the Palmaz stent is a useful procedure for the treatment of native or post-operative pulmonary stenosis. It is possible to apply it to hypoplastic and ostial pulmonary stenosis. We confirm the effectiveness of redilatation at mid term.

RESUMEN

We report the case of a symptomatic adult with an occluded persistent duct with a transcatheter proceeding using a Rashkind prosthesis. After a month of follow up the color-coded Doppler-flow echocardiogram did not show residual shunt, posteriorly the patient's symptoms disappeared and the left ventricular dimensions were reduced. At the thirteen month of follow-up, the patient had an accident while working, falling down from a scaffold. Afterwards, a ductal jet was observed in the echocardiogram with an increased size of the left ventricle, symptoms also appeared. A cardiac catheterism was then performed showing a pulmonary/systemic flow rate of 2 and a 3 mm flow jet at the superior border of the prosthesis. A second prosthesis was implanted with no residual shunts.

RESUMEN

The reflex-induced cardiovascular syncope is rarely associated with facial neuralgia and neck neoplasms. We report the case of a male with vasopressor and cardioinhibitor syncopes, despite the implantation of a pacemaker. Because of a glossopharyngeal neuralgia, a neoplasm of the left parapharyngeal fossae is diagnosed. The pathophysiology and the therapeutic approach is discussed.

RESUMEN

We report the case of a young male with an inferior myocardial infarction who was treated with fibrinolytic agents and displayed a good evolution. The only cardiovascular risk factor that this patient had was an idiopathic thrombocytosis with abnormal platelet hyperreactivity tests. The angiogram showed an eccentric lesion of 60% in the left main coronary artery. A week later, after treatment based on anticoagulants and antithrombotic agents the angiogram was normal, and the lesion had disappeared. The association between these conditions is discussed the therapeutic approach is also discussed. A review of the literature is conducted.

RESUMEN

Intermittent aortic regurgitation is an unusual complication following a mechanical prosthesis replacement in the early postoperative period. Arterial pressure recording and echocardiographic assessment were enough to diagnose the prosthetic dysfunction. Reexploration of the valve confirmed the dysfunction, which was caused by a pannus of previous aortic valve replacement with the pulmonary valve. The pannus impeded normal closure of the leaflet in an intermittent way during diastole. Reorientation of the valve corrected the aortic insufficiency. Doppler ultrasound was a very useful noninvasive technique in order to evaluate the suspected prosthetic valve dysfunction in the immediate postoperative period.

RESUMEN

Anthracyclines are very effective antineoplastic agents for the treatment of acute leukemia. Early and late dose-related cardiotoxicity can occur. We present a 33 year old women who developed a reversible right heart failure fifteen days after receiving a treatment with doxorubicine. Severe regional wall motion abnormalities were appreciated through two-dimensional and Doppler-flow echocardiography, there was no evidence of impaired systolic or diastolic left ventricle function. Two weeks later, remission of acute right ventricle failure was obtained, echocardiographic assessment was normal at this time. Incidence of right ventricle abnormalities after treatment is discussed.

RESUMEN

We present a 36-year-old male without overt cardiac disease who suffered, since he was 15 years old, from sustained monomorphic ventricular tachycardia of left bundle branch block with a right axis, lasting for several hours; sometimes, syncope was a clinical form of manifestation. Electrophysiologic study, twenty-four hours Holter recording, cardiac catheterization and blood analysis were not useful in order to find its etiology. Efficacy of different drugs, like Mexiletil, Amiodarone, Atenolol and Verapamil (at a dose of 240 mg/day) were tested through multistaged graded-treadmill stress-testing using the Bruce protocol. Ventricular tachycardia was suppressed by administration of Lidocaine. Oral verapamil given at a dose of 360 mg/day prevented the induction of the arrhythmia, the efficacy was tested with maximal treadmill exercise and twenty-four hours Holter recording.

RESUMEN

OBJECTIVES: In order to study the efficiency of oral dose of propafenone in preventing childhood supraventricular tachycardias, we have treated 38 children without left ventricular dysfunction. METHODS: The mean age has been 8 +/- 4.7 years old. All of them had suffered at least two episodes of supraventricular tachycardia, and eleven had undergone a previous antiarrhythmic treatment. The initial dose of propafenone has been 6.5 +/- 2.1 mg/kg/24 h (in 3 doses), which has been increased in case of inefficacy. RESULTS: We have not advised neither side-effects, nor proarrhythmic effects, during a follow-up of 13 +/- 6 months. Propafenone has been efficient in preventing supraventricular tachycardias in all patients. The initial dose has been efficient in 17 patients, and we have increased the initial dose up to 11.1 +/- 3.7 mg/kg/24 h in 21 patients. The mean effective dose has been 8.9 +/- 3.6 mg/kg/24 h. We stopped treatment in 14 patients after been 6 months without supraventricular tachycardias. CONCLUSION: From our study, we conclude that propafenone has been efficient in preventing supraventricular tachycardias in childhood with a dose of 8.9 mg/kg/24 h. We have not found side-effects.

RESUMEN

BACKGROUND: To valorate the effect of four antihypertensive drugs on the regression of cardiac mass and diastolic function, by echocardiography-Doppler, in not treated hypertensive subjects. METHODS: 60 mild-moderate hypertensive subjects were studied randomized in four groups of 15 patients each one: enalapril (10-40 mg/d), atenolol (25-100 mg/d), verapamil-retard (120-240 mg/d), alphametildopa (250 mg/8h to 3 g/d). The active drug therapy phase was 6 months, performing echo-Doppler, evaluating posterior-wall and septal-wall thicknesses, ventricular mass index, ratio of early to atrial peak diastolic filling velocity (E/A), the first-third filling fraction and atrial filling fraction. RESULTS: The cardiac mass index decreased with the four drugs: with enalapril from 178 +/- 28 to 155 +/- 29 g/m2 (p < 0.05), with atenolol from 170 +/- 23 to 154 +/- 19 g/m2 (p < 0.05), with verapamil from 180 +/- 27 to 159 +/- 22 g/m2 (p < 0.05) and with alphametildopa from 176 +/- 30 to 142 +/- 22 g/m2 (p < 0.01). The E/A ratio and first-third filling fraction only improved in the atenolol subgroup, from 0.79 +/- 0.13 to 0.97 +/- 0.16 (p < 0.01) and from 36 +/- 5 to 44 +/- 9% (p < 0.01), decreasing atrial filling fraction from 37 +/- 6 to 30 +/- 8% (p < 0.01), without modifying with enalapril (0.74 +/- 0.14 to 0.76 +/- 0.20, 35 +/- 5% to 36 +/- 7%, 38 +/- 5 to 39 +/- 7%, p = NS), verapamil (0.69 +/- 0.12 to 0.74 +/- 0.17, 35 +/- 6% to 36 +/- 8% to 40 +/- 12%, p = NS) neither alphametildopa (0.72 +/- 0.14 to 0.71 +/- 0.21, 34 +/- 5% to 35 +/- 7%, 40 +/- 6% to 41 +/- 9%, p = NS). The heart rate decreased more with atenolol than with the other drugs (61 +/- 15 vs 71 +/- 12, p < 0.01). CONCLUSIONS: In hypertensive patients the decreasing of cardiac mass is not accompanied of improvement of the diastolic function except in patients treated with atenolol, probably due to bradycardia.

RESUMEN

This report describe a 69-year old woman with a congenital aneurysm of the non-coronary sinus of Valsalva ruptured in the right atrium, causing severe hemodynamic derangement of the right ventricle. The site of the communication between the aneurysm and the receiving chamber was accurately diagnosed by two-dimensional color flow Doppler imaging which provided more valuable preoperative information than conventional aortography.
