RESUMEN

BACKGROUND: There is little information of progestogen-only contraceptives in patients with congenital heart disease (CHD) on the long-term. OBJECTIVE: To evaluate the use of contraception in patients with CHD. We studied both short-acting reversible contraceptives (SARCs), oral progestin-only pills (POPs) and long-acting reversible contraceptives (LARCs): intrauterine devices (IUD-IPs) and subdermal implants both impregnated with progestogens (SI-IPs). STUDY DESIGN: Retrospective study of all women attending the preconception clinic. Contraceptive methods were classified in three TIERs of effectiveness before and after consultation. ESC classification regarding pregnancy risk, WHOMEC classification for combined oral contraceptive safety was collected. RESULTS: Six hundred and fifty-three patients. A significant proportion of them switched from TIER 3 to TIER 2 or 1 (p < .001) after consultation. One hundred and ninety-nine patients used POPs, 53 underwent IUD-IPs implantation and 36 SI-IPs, mean duration was 58 ± 8, 59 ± 8 and 53 ± 38 months, respectively. CONCLUSIONS: Because of their safety and efficacy, IUD-IPs and SI-IPs should be considered as first-line contraception in patients with CHD.


We looked at the use of progestogen-only contraceptives in women with congenital heart disease (CHD) over a long period and determine how safe and effective these contraceptives are for such patients. We considered two types of contraceptives: short-acting ones like progestin-only pills (POPs) and long-acting ones like intrauterine devices and subdermal implants that release progestogens.We gathered information from 653 women and assessed how women's contraceptive choices changed before and after they had a consultation with us.After consulting with our clinic, a significant number of women switched from less effective contraceptives to more effective ones. Among the women who used POPs, most of them followed the prescribed regimen quite well. Additionally, 89 women used long-acting contraceptives, without failure of method.In conclusion, our findings suggest that long-acting progestogen-only contraceptives are safe and effective choices for contraception in women with CHD. Therefore, these options should be considered as the first choice.

RESUMEN

This is a prospective, observational study, conducted in a tertiary referral hospital. We enrolled 175 singleton pregnancies with estimated foetal weight below the 10th centile between 20 + 0 and 31 + 6 weeks. Placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and fetoplacental circulation were assessed at the time of diagnosis. Receiver operating characteristic curves were used to assess the performance of sFlt-1/PlGF for predicting adverse perinatal outcomes (APO). The optimal cut-offs to predict each adverse outcome were calculated and the resulting areas under the curve (AUC) were compared to those calculated from the cut-off points of 38, 85 and 110. The need for delivery at <30 and <34 weeks and APO were the main outcome measures. The optimal cut-off points to predict APO, delivery <30 and <34 weeks were 24.9, 116.7 and 97.5, respectively. None of them proved to be superior to 38, 85 or 110 for predicting any adverse pregnancy outcome. Impact StatementWhat is already known on this subject? Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) are biomarkers of placental dysfunction. High sFlt-1/PlGF values predict adverse perinatal outcomes in preeclampsia (PE).What do the results of this study add? No specific thresholds have been described to identify early-onset foetal growth restriction (FGR) and small for gestational age (SGA) foetuses at higher risk of adverse outcomes. This study describes these specific cut-offs and compares their predictive capacity to those described for PE.What are the implications of these findings for clinical practice and/or further research? The sFlt-1/PlGF cut-off points of 38, 85 and 110 might be useful for ruling out the occurrence of APO and the need for elective delivery at <30 and at <34 weeks from the moment of diagnosis in early-onset FGR and SGA. These cut-offs could aid Doppler studies in the distinction between FGR and SGA.

RESUMEN

OBJECTIVE: Pre-eclampsia (PE) and small for gestational age (SGA) can be predicted from the first trimester. The most widely used algorithm worldwide is the Fetal Medicine Foundation (FMF) algorithm. The recently described Gaussian algorithm has reported excellent results although it is unlikely to be externally validated. Therefore, as an alternative approach, we compared the predictive accuracy for PE and SGA of the Gaussian and FMF algorithms. METHODS: Secondary analysis of a prospective cohort study was conducted at Vall d'Hebron University Hospital (Barcelona) with 2641 singleton pregnancies. The areas under the curve for the predictive performance for early-onset and preterm PE and early-onset and preterm SGA were calculated with the Gaussian and FMF algorithms and subsequently compared. RESULTS: The FMF and Gaussian algorithms showed a similar predictive performance for most outcomes and marker combinations. Nevertheless, significant differences for early-onset PE prediction favored the Gaussian algorithm in the following combinations: mean arterial blood pressure (MAP) with pregnancy-associated plasma protein A, MAP with placental growth factor, and MAP alone. CONCLUSIONS: The first-trimester Gaussian and FMF algorithms have similar performances for PE and SGA prediction when applied with all markers within a routine care setting in a Spanish population, adding evidence to the external validity of the FMF algorithm.

RESUMEN

Aberrant promoter hypermethylation is common in oral squamous cell carcinoma (OSCC) and may be useful as a marker for cancer cells. The aim of our study was to assess whether the detection of hypermethylation of the promoter region of p16(INK4a) in oral cytological samples could be a marker in patients with risk of developing an OSCC. Hypermethylation was detected in 20% (29/145) of the cases analyzed. These findings provide further evidence that the inactivation of p16(INK4a), due to methylation, is an early event in the carcinogenic pathway of OSCC.

RESUMEN

Scraped (exfoliative) cytology is a simple and harmless procedure, which has been a controversial technique according to its real validity in oral pathology. Lately it has re-emerged due to its application in oral precancer and cancer as a diagnostic and predictive method as well as for monitoring patients. New diagnostic techniques have been developed, such as "brush biopsy" and multiple molecular studies using the cells collected. In this review we are going to analyse the more novel aspects related with the applications of the scraped or exfoliative cytology in oral precancerous and cancerous pathology, specially focusing on molecular studies and their diagnostic and prognostic implications.

RESUMEN

The use of Radio Frequency IDentification Technology (RFID) in the packaging sector is an important logistical improvement regarding the advantages offered by this technology in comparison with barcodes. Nevertheless, the presence of these devices in plastic packaging, and consequently in plastic waste, can cause several problems in the recycling plants due to the materials included in these devices. In this study, the mentioned recycling constraints have been experimentally identified in a pilot scale recycling study consisting in three recycling tests with an increasing presence of RFID tags. Differences in each test were evaluated. Furthermore, the quality of the recycled material of each test was studied through the injection and testing of tests probes. The results of the pilot scale recycling tests did not show a decrease in the quality of the recycled plastic due to the presence of RFID tags. Nevertheless, several operational problems during the recycling process were observed such as the obstruction of the screens, which lessened the process yield and created process interruptions, as well as the loss of extruded plastic during the process. These recycling constraints cannot be directly extrapolated to the industrial plants due to the different working scales. Nevertheless, technological solutions are proposed in order to avoid these recycling constraints if they appear.

RESUMEN

La citología por raspado es un procedimiento simple e incruente que ha sido objeto de controversia sobre su validez real en patología oral. En los últimos tiempos ha resurgido en base a su aplicación en el precáncer y el cáncer oral, tanto como metodología diagnóstica como predictiva y para la monitorización de los pacientes. Se han desarrollado nuevas técnicas sobre aspectos diagnósticos, como la aplicación “brush biopsy”, y múltiples estudios moleculares sobre las células recogidas. En esta revisión analizamos los aspectos más novedosos en relación con las aplicaciones de la citología por raspado o exfoliativa en la patología oral cancerosa y precancerosa, dirigida de un modo especial a los estudios moleculares y sus implicaciones diagnósticas y pronósticas
