RESUMO

INTRODUCTION: Approximately every fourth labor is induced. In Finland, when labor is induced, it is commonly carried out with a catheter in the inpatient (IP) setting. However, in uncomplicated, full-term pregnancies, induction of labor (IOL) in the outpatient (OP) setting is also possible. Nevertheless, there is only a limited amount of information about the experiences of IOL in OP setting. Our study compared the experiences of catheter IOL in OP and IP settings. MATERIAL AND METHODS: We performed a prospective randomized study, including 113 women with uncomplicated full-term pregnancies with planned IOL. After catheter insertion, women were randomized into OP or IP settings: after dropouts, there were 53 women in the OP group and 54 in the IP. The experiences of IOL were evaluated with three sets of visual analog scale (VAS) questionnaires: the general experience questionnaire (eight questions), the concurrent induction experience questionnaire (1, 5, 9, 13 hours; nine questions) and the postpartum experience questionnaire (14 questions). RESULTS: Both groups had low VAS scores, indicating good experiences of IOL. Women in the OP group were less satisfied (mean VAS difference Δ = 7.8, P = .015) and more anxious (Δ = 4.8, P = .008) than were women in the IP group. In the course of the IOL, all women became less satisfied (Δ = 8.4, P = .001), had more contraction pain (Δ = 8.9, P = .020) and had a higher frequency of contractions (Δ = 9.9, P = .004) but they were more relaxed and experienced less fear (Δ = 6.9, P = .036, Δ = 5.3, P = .001, respectively). There was no interaction between group and time. According to the postpartum experience questionnaire, both groups had a similar good general experience of IOL (P = .736) but the OP group had more fear (Δ = 9.5, P = .009) and was more anxious (Δ = 9.0, P = .007). Most of the women would choose catheter IOL in a subsequent pregnancy (OP 82.6%, IP 87.0%). CONCLUSIONS: The women in the OP setting were less satisfied and more anxious than were the women in the IP setting. However, the differences were marginal and the general experience after IOL was good. IOL in an OP setting is thus a viable option in low-risk full-term pregnancies. Therefore, when using catheter IOL, both setting options should be available.

RESUMO

OBJECTIVE: Depressive symptoms and sleep disturbances have been found to be associated with negative labor experiences, particularly an increased level of pain. However, the associations between maternal depressive symptoms and sleep disturbances and the experience of induction of labor (IOL) remain unknown. In this study, we evaluated these associations with balloon catheter IOL. STUDY DESIGN: A prospective study was conducted on 106 women with planned IOL. Depressive symptoms were evaluated with The Edinburg Postnatal Depression Scale (EPDS) and sleep disturbances with the Basic Nordic Sleep Questionnaire (BNSQ) at the beginning of IOL. The IOL experience was investigated both during the IOL and postpartum with the same nine visual analogue scale (VAS) questions. RESULTS: Regarding sleep disturbances, during the IOL, women with worse general sleep quality were less satisfied (P = 0.019), less relaxed (P = 0.008), experienced more pain in general (P = 0.002) and reported higher contraction frequency (P = 0.003). Furthermore, women who experienced difficulties falling asleep were less relaxed (P = 0.009), reported more general pain (P < 0.001) and contraction pain (P = 0.005), while those with more daytime sleepiness reported less contraction pain (P = 0.033). In postpartum, women with worse general sleep quality reported more general pain (P = 0.003), while women with longer sleep duration and those with higher sleep loss reported more anxiety (P = 0.009 and P = 0.024, respectively). Additionally, women who woke up too early in the morning were less satisfied (P = 0.042), less relaxed (P = 0.004) and reported more general pain (P = 0.018). However, those who experienced more frequent nocturnal awakenings reported being more relaxed (P = 0.014) and having less general pain (P = 0.033). Higher depressive symptoms were associated with a higher frequency of contractions during IOL (P = 0.030), but with less general pain in postpartum (P = 0.027). CONCLUSIONS: Women with sleep disturbances during pregnancy were more likely to report more negative experiences during the IOL. Specifically, they reported more pain, feeling less relaxed and they were less satisfied with IOL. Conversely, the association between depressive symptoms and the experience of IOL seemed weaker. Thus, the quality of sleep of pregnant women is important for a better experience of IOL.

RESUMO

OBJECTIVES: Pregnancy-Unique Quantification of Emesis (PUQE) questionnaire is mainly used in outpatient care to assess the severity of nausea and vomiting of pregnancy (NVP). Our aim was to evaluate the usability of the Finnish-translated PUQE in hospitalised women with hyperemesis gravidarum (HG). DESIGN: Prospective cohort study. SETTING: University hospital in Finland. PARTICIPANTS: Ninety-five women admitted due to HG for at least overnight. PRIMARY AND SECONDARY OUTCOME MEASURES: Categorised and continuous PUQE scores, physical and mental quality of life (QoL) and urine ketones at admission and at discharge, analysing the first admission and readmissions separately. RESULTS: The most common PUQE categories at admission were 'moderate' and 'severe', whereas at discharge they were 'mild' and 'moderate'. Likewise, continuous PUQE scores improved between admission and discharge (p<0.0001). At admission, women rating worse physical QoL (first admission adjusted OR (AOR) 1.09; 95% CI 1.03 to 1.16; readmissions AOR 1.13; 95% CI 1.02 to 1.25) and women with ketonuria of +++ (first admission AOR 16.00; 95% CI 1.44 to 177.82) fell into higher PUQE score category. On discharge day, women with better physical QoL had lower PUQE score category (first admission AOR 0.94; 95% CI 0.91 to 0.98; readmissions AOR 0.93; 95% CI 0.90 to 0.97). The results between physical QoL and continuous PUQE scores were similar. Concerning readmissions, better mental QoL was associated with lower PUQE score category at discharge (AOR 0.93; 95% CI 0.89 to 0.97). As for continuous PUQE score, worse mental QoL was associated with higher score at admission (readmissions, p=0.007) and better mental QoL with lower score at discharge (readmissions, p=0.007). CONCLUSIONS: PUQE scores reflected alleviation of NVP severity in women hospitalised due to HG. Further, the decrease in PUQE score was associated with improved physical QoL and partly also with improved mental QoL. We therefore suggest PUQE as a complementary instrument for inpatient setting.

RESUMO

Current cardiac drug safety assessments focus on hERG channel block and QT prolongation for evaluating arrhythmic risks, whereas the optogenetic approach focuses on the action potential (AP) waveform generated by a monolayer of human cardiomyocytes beating synchronously, thus assessing the contribution of several ion channels on the overall drug effect. This novel tool provides arrhythmogenic sensitizing by light-induced pacing in combination with non-invasive, all-optical measurements of cardiomyocyte APs and will improve assessment of drug-induced electrophysiological aberrancies. With the help of patch clamp electrophysiology measurements, we aimed to investigate whether the optogenetic modifications alter human cardiomyocytes' electrophysiology and how well the optogenetic analyses perform against this gold standard. Patch clamp electrophysiology measurements of non-transduced stem cell-derived cardiomyocytes compared to cells expressing the commercially available optogenetic constructs Optopatch and CaViar revealed no significant changes in action potential duration (APD) parameters. Thus, inserting the optogenetic constructs into cardiomyocytes does not significantly affect the cardiomyocyte's electrophysiological properties. When comparing the two methods against each other (patch clamp vs. optogenetic imaging) we found no significant differences in APD parameters for the Optopatch transduced cells, whereas the CaViar transduced cells exhibited modest increases in APD-values measured with optogenetic imaging. Thus, to broaden the screen, we combined optogenetic measurements of membrane potential and calcium transients with contractile motion measured by video motion tracking. Furthermore, to assess how optogenetic measurements can predict changes in membrane potential, or early afterdepolarizations (EADs), cells were exposed to cumulating doses of E-4031, a hERG potassium channel blocker, and drug effects were measured at both spontaneous and paced beating rates (1, 2 Hz). Cumulating doses of E-4031 produced prolonged APDs, followed by EADs and drug-induced quiescence. These observations were corroborated by patch clamp and contractility measurements. Similar responses, although more modest were seen with the IKs potassium channel blocker JNJ-303. In conclusion, optogenetic measurements of AP waveforms combined with optical pacing compare well with the patch clamp gold standard. Combined with video motion contractile measurements, optogenetic imaging provides an appealing alternative for electrophysiological screening of human cardiomyocyte responses in pharmacological efficacy and safety testings.

RESUMO

Efficient and robust subcloning is essential for the construction of high-diversity DNA libraries in the field of directed evolution. We have developed a more efficient method for the subcloning of DNA-shuffled libraries by employing recombination cloning (Gateway). The Gateway cloning procedure was performed directly after the gene reassembly reaction, without additional purification and amplification steps, thus simplifying the conventional DNA shuffling protocols. Recombination-based cloning, directly from the heterologous reassembly reaction, conserved the high quality of the library and reduced the time required for the library construction. The described method is generally compatible for the construction of DNA-shuffled gene libraries.
