RESUMO

Cervical ripening is a critical component of normal parturition. There are substantial variations in labour induction (IOL) techniques around the world. Mifepristone causes the termination of unwanted pregnancies, but there is a lack of consensus on its use for labour induction. The purpose of our study was to compare the combination of Mifepristone and Misoprostol with the combination of a Foley balloon and Misoprostol for labour induction. The study included 175 pregnant women, with gestational age 37-42 weeks. In the study group - 88 pregnant aged 21-35 (28.56±3.23), a combination of Mifepristone-Misoprostol was used. A combination of Foley catheter and Misoprostol was used in the control group - 87 pregnant aged 21-35 (29.48±3.03). The outcomes were assessed. In the study group the rate of vaginal delivery was higher and the frequency of cesarean section was lower compared to the control group (75 vs. 72, and 13 vs. 15, respectively); The total duration of labour was shorter in the study group (p<0,05); There was no difference between groups in the incidences of neonatal morbidity on the first and the fifth minute of life (p>0,05); The pain level was significantly low in the study group compared to the control group (5±0,75 vs. 8±0,96) and no cervical laceration was revealed in the study group. The Mifepristone - Misoprostol combination has advantages over the Foley balloon - Misoprostol combination for induction of labour regarding reduction in pain intensity, duration of labour, and cervical laceration.

RESUMO

OBJECTIVE: To compare the outcomes of termination of pregnancy with live fetuses in the second trimester (14-28 weeks), using misoprostol 400 mcg intravaginal every 6 h, between women with previous cesarean section (PCS) and no previous cesarean section (no PCS). METHODS: A comparative study was conducted on a prospective database of pregnancy termination in the second trimester, Chiang Mai university hospital. Inclusion criteria included: (1) singleton pregnancy; (2) gestational age between 14 and 28 weeks; and (3) pregnancy with a live fetus and medically indicated for termination. The participants were categorized into two groups; PCS and no PCS group. All were terminated using misoprostol 400 mcg intravaginal every 6 h. The main outcomes were induction to fetal delivery interval and success rate, defined as fetal delivery within 48 h. RESULTS: A total of 238 women, including 80 PCS and 158 no PCS, were recruited. The success rate of fetal delivery within 48 h between both groups was not significantly different (91.3% vs. 93.0%; p-value 0.622). The induction to fetal delivery interval were not significantly different (1531 vs. 1279 min; p-value > 0.05). Gestational age was an independent factor for the success rate and required dosage of misoprostol. The rates of most adverse effects of misoprostol were similar. One case (1.3%) in the PCS group developed uterine rupture during termination, ending up with safe and successful surgical removal and uterine repair. CONCLUSION: Intravaginal misoprostol is highly effective for second trimester termination of pregnancy with PCS and those with no PCS, with similar success rate and induction to fetal delivery interval. Gestational age was an independent factor for the success rate and required dosage of misoprostol. Uterine rupture could occur in 1.3% of PCS, implying that high precaution must be taken for early detection and proper management. SYNOPSIS: Intravaginal misoprostol is highly effective for termination of second trimester pregnancy with a live fetus, with a comparable success rate between women with and without previous cesarean section, with a 1.3% risk of uterine rupture among women with previous cesarean section.

RESUMO

Misoprostol is a prostaglandin analogue that contracts the uterus, prompting the expulsion of the embryo. No systematic evaluation of the mechanisms of misoprostol has previously been performed. In this study, known targets of misoprostol were obtained from the DrugBank database; potential targets of misoprostol were predicted using data from the SwissTargetPrediction and PharmMapper databases; and the main targets of pregnancy termination were obtained from the GeneCards database. The protein-protein interaction (PPI) network of the shared genes between misoprostol and pregnancy termination was constructed using data from the STRING database, and the "misoprostol-pregnancy termination-pathway" network was constructed and potential targets was verified through molecular docking. We analyzed 37 shared target genes and obtained a network diagram of 134 potential targets, which the core therapeutic targets were HSP90AA1, EGFR, and MAPK1. GO functional and KEGG pathway enrichment analyses showed that misoprostol can modulate the VEGF signaling pathway, calcium signaling pathway, and NF-κB signaling pathway in pregnancy termination and mainly interferes with protein phosphorylation, cell localization, and protein hydrolysis regulation processes. This research illustrates the mechanism underlying the pharmacological effect of misoprostol, namely pregnancy termination. However, further experimental verification is warranted for optimal use of misoprostol during clinical practice.


Le misoprostol est un analogue des prostaglandines qui contracte l'utérus, provoquant l'expulsion de l'embryon. Aucune évaluation systématique des mécanismes du misoprostol n'a été réalisée auparavant. Dans cette étude, les cibles connues du misoprostol ont été obtenues à partir de la base de données DrugBank ; Les cibles potentielles du misoprostol ont été prédites à l'aide des données des bases de données SwissTargetPrediction et PharmMapper ; et les principales cibles de l'interruption de grossesse ont été obtenues à partir de la base de données GeneCards. Le réseau d'interaction protéine-protéine (IPP) des gènes partagés entre le misoprostol et l'interruption de grossesse a été construit à l'aide des données de la base de données STRING, et le réseau « voie d'interruption de grossesse-misoprostol ¼ a été construit et les cibles potentielles ont été vérifiées par amarrage moléculaire. Nous avons analysé 37 gènes cibles partagés et obtenu un diagramme de réseau de 134 cibles potentielles, dont les principales cibles thérapeutiques étaient HSP90AA1, EGFR et MAPK1. Les analyses d'enrichissement des voies fonctionnelles GO et KEGG ont montré que le misoprostol peut moduler la voie de signalisation VEGF, la voie de signalisation du calcium et la voie de signalisation NF-κB lors de l'interruption de grossesse et interfère principalement avec les processus de phosphorylation des protéines, de localisation cellulaire et de régulation de l'hydrolyse des protéines. Cette recherche illustre le mécanisme sous-jacent à l'effet pharmacologique du misoprostol, à savoir l'interruption de grossesse. Cependant, une vérification expérimentale plus approfondie est justifiée pour une utilisation optimale du misoprostol au cours de la pratique clinique.

RESUMO

BACKGROUND: Misoprostol is a well-studied medical treatment for early pregnancy loss (EPL), with success rates ranging between 70 and 90%. However, treatment failure is associated with major patient discomfort, including the need for surgical intervention to evacuate the uterus. It was previously reported that medical treatment was especially successful among women who conceived after in vitro fertilization (IVF). We aimed to study if there is a difference in rates of medical treatment failures for EPL between pregnancies conceived by IVF and spontaneous pregnancies. METHODS: In this retrospective cohort study, we included all women who underwent medical treatment for EPL at our institute between 07/2015 and 12/2020. Treatment outcome was compared between IVF and spontaneous pregnancies. Treatment failure was defined as a need for surgical intervention, namely, dilation & curettage (D&C) and/or hysteroscopy, due to retained products of conception, which was defined as a gestational sac or endometrial thickness greater than 15 mm in a TVS scan. RESULTS: Overall, 775 patients were included, of which 195 (169/775 = 25.1%) ultimately required surgical intervention. There was no difference between the study groups in the rate of treatment failure. However, among IVF pregnancies, the rate of emergency D&C was lower (3.6% vs. 9.8%, p = 0.001), compared to spontaneous group. CONCLUSION: In cases of medical treatment for EPL, IVF pregnancies had no differences in rates of treatment failure compared to spontaneous pregnancies. That being said, IVF pregnancies have lower chances to undergo emergency D&C, compared to spontaneous pregnancies.

RESUMO

We tested five chemically and metabolically stable prostaglandin (PG) receptor agonists in a mouse model of dexamethasone-induced ocular hypertension (OHT). Whilst all compounds significantly (p < 0.05, ANOVA) lowered intraocular pressure (IOP) after twice-daily bilateral topical ocular dosing (5 µg/dose) over three weeks, the time course and magnitude of the responses varied. The onset of action of NS-304 (IP-PG receptor agonist) and rivenprost (EP4-PG receptor agonist) was slower than that of misoprostol (mixed EP2/EP3/EP4-PG receptor agonist), PF-04217329 (EP2-PG receptor agonist), and butaprost (EP2-PG receptor agonist). The rank order of IOP-lowering efficacies aligned with the onset of actions of these compounds. Peak IOP reductions relative to vehicle controls were as follows: misoprostol (74.52%) = PF-04217329 (74.32%) > butaprost (65.2%) > rivenprost (58.4%) > NS-304 (55.3%). A literature survey indicated that few previously evaluated compounds (e.g., latanoprost, timolol, pilocarpine, brimonidine, dorzolamide, cromakalim analog (CKLP1), losartan, tissue plasminogen activator, trans-resveratrol, sodium 4-phenyl acetic acid, etc.) in various animal models of steroid-induced OHT were able to match the effectiveness of misoprostol, PF-04217329 or butaprost. Since a common feature of the latter compounds is their relatively high affinity and potency at the EP2-PG receptor sub-type, which activates the production of intracellular cAMP in target cells, our studies suggest that drugs selective for the EP2-PG receptor may be suited to treat corticosteroid-induced OHT.

RESUMO

This review assessed the efficacy and safety of pharmacologic agents (prostaglandins, oxytocin, mifepristone, hyaluronidase, and nitric oxide donors) and mechanical methods (single- and double-balloon catheters, laminaria, membrane stripping, and amniotomy) and those generally considered under the rubric of complementary medicine (castor oil, nipple stimulation, sexual intercourse, herbal medicine, and acupuncture). A substantial body of published reports, including 2 large network meta-analyses, support the safety and efficacy of misoprostol (PGE1) when used for cervical ripening and labor induction. Misoprostol administered vaginally at doses of 50 µg has the highest probability of achieving vaginal delivery within 24 hours. Regardless of dosing, route, and schedule of administration, when used for cervical ripening and labor induction, prostaglandin E2 seems to have similar efficacy in decreasing cesarean delivery rates. Globally, although oxytocin represents the most widely used pharmacologic agent for labor induction, its effectiveness is highly dependent on parity and cervical status. Oxytocin is more effective than expectant management in inducing labor, and the efficacy of oxytocin is enhanced when combined with amniotomy. However, prostaglandins administered vaginally or intracervically are more effective in inducing labor than oxytocin. A single 200-mg oral tablet of mifepristone seems to represent the lowest effective dose for cervical ripening. The bulk of the literature assessing relaxin suggests this agent has limited benefit when used for this indication. Although intracervical injection of hyaluronidase may cause cervical ripening, the need for intracervical administration has limited the use of this agent. Concerning the vaginal administration of nitric oxide donors, including isosorbide mononitrate, isosorbide, nitroglycerin, and sodium nitroprusside, the higher incidence of side effects with these agents has limited their use. A synthetic hygroscopic cervical dilator has been found to be effective for preinduction cervical ripening. Although a pharmacologic agent may be administered after the use of the synthetic hygroscopic dilator, in an attempt to reduce the interval to vaginal delivery, concomitant use of mechanical and pharmacologic methods is being explored. Combining the use of a single-balloon catheter with dinoprostone, misoprostol, or oxytocin enhances the efficacy of these pharmacologic agents in cervical ripening and labor induction. The efficacy of single- and double-balloon catheters in cervical ripening and labor induction seems similar. To date, the combination of misoprostol with an intracervical catheter seems to be the best approach when balancing delivery times with safety. Although complementary methods are occasionally used by patients, given the lack of data documenting their efficacy and safety, these methods are rarely used in hospital settings.

RESUMO

OBJECTIVE: This study aims to compare the safety and efficacy of misoprostol administered orally and vaginally in obese pregnant women at term with either gestational hypertension or diabetes. METHODS: A total of 264 pregnant women were enrolled and categorized into two groups based on their primary condition: hypertension (134 cases) or diabetes mellitus (130 cases) and were further divided into subgroups for misoprostol administration: orally (Oral group) or vaginally (Vaginal group). The primary outcomes measured were changes in the Bishop score following treatment, induction of labor (IOL) success rates, requirement for oxytocin augmentation, duration of labor, mode of delivery, and cesarean section rates. RESULTS: Significant enhancements in Bishop scores, decreased cesarean section rates and increased success rates of IOL were noted in both administration groups. The incidence of vaginal delivery within 24 h was significantly higher in the Vaginal group compared to the Oral group. Adverse effects, including nausea, uterine overcontraction, hyperfrequency of uterine contraction and uterine hyperstimulation without fetal heart rate deceleration, were significantly more prevalent in the Vaginal group than in the Oral group. CONCLUSION: Misoprostol administration, both orally and vaginally, proves effective for labor induction in obese pregnant women with hypertension or diabetes. However, the oral route presents a lower risk of adverse maternal and neonatal outcomes, suggesting its preference for safer labor induction in this demographic.

RESUMO

OBJECTIVE: Several systematic reviews and meta-analyses have been conducted to summarize the evidence for the efficacy of various labor induction agents. However, the most effective agents or strategies have not been conclusively determined. We aimed to perform a meta-review and network meta-analysis of published systematic reviews to determine the efficacy and safety of currently employed pharmacologic, mechanical, and combined methods of labor induction. DATA SOURCES: With the assistance of an experienced medical librarian, we performed a systematic search of the literature using PubMed, EMBASE, and the Cochrane Central Register of Control Trials. We systematically searched electronic databases from inception to May 31, 2021. STUDY ELIGIBILITY CRITERIA: We considered systematic reviews and meta-analyses of randomized controlled trials comparing different agents or methods for inpatient labor induction. METHODS: We conducted a frequentist random-effects network meta-analysis employing data from randomized controlled trials of published systematic reviews. We performed direct pairwise meta-analyses to compare the efficacy of the various labor induction agents and placebo or no treatment. We performed ranking to determine the best treatment using the surface under the cumulative ranking curve. The main outcomes assessed were cesarean delivery, vaginal delivery within 24 hours, operative vaginal delivery, hyperstimulation, neonatal intensive care unit admissions, and Apgar scores of <7 at 5 minutes of birth. RESULTS: We included 11 systematic reviews and extracted data from 207 randomized controlled trials with a total of 40,854 participants. When assessing the efficacy of all agents and methods, the combination of a single-balloon catheter with misoprostol was the most effective in reducing the odds of cesarean delivery and vaginal birth >24 hours (surface under the cumulative ranking curve of 0.9 for each). Among the pharmacologic agents, low-dose vaginal misoprostol was the most effective in reducing the odds of cesarean delivery, whereas high-dose vaginal misoprostol was the most effective in achieving vaginal delivery within 24 hours (surface under the cumulative ranking curve of 0.9 for each). Single-balloon catheter (surface under the cumulative ranking curve of 0.8) and double-balloon catheter (surface under the cumulative ranking curve of 0.9) were the most effective in reducing the odds of operative vaginal delivery and hyperstimulation. Buccal or sublingual misoprostol (surface under the cumulative ranking curve of 0.9) and the combination of single-balloon catheter and misoprostol (surface under the cumulative ranking curve of 0.9) most effectively reduced the odds of abnormal Apgar scores and neonatal intensive care unit admissions. CONCLUSION: The combination of a single-balloon catheter with misoprostol was the most effective method in reducing the odds for cesarean delivery and prolonged time to vaginal delivery. This method was associated with a reduction in admissions to the neonatal intensive care unit.

RESUMO

OBJECTIVE: Several systematic reviews and meta-analyses have summarized the evidence on the efficacy and safety of various outpatient cervical ripening methods. However, the method with the highest efficacy and safety profile has not been determined conclusively. We performed a systematic review and network meta-analysis of published randomized controlled trials to assess the efficacy and safety of cervical ripening methods currently employed in the outpatient setting. DATA SOURCES: With the assistance of an experienced medical librarian, we performed a systematic search of the literature using MEDLINE, Embase, Scopus, Web of Science, Cochrane Library, and ClinicalTrials.gov. We systematically searched electronic databases from inception to January 14, 2020. STUDY ELIGIBILITY CRITERIA: We considered randomized controlled trials comparing a variety of methods for outpatient cervical ripening. METHODS: We conducted a frequentist random effects network meta-analysis employing data from randomized controlled trials. We performed a direct, pairwise meta-analysis to compare the efficacy of various outpatient cervical ripening methods, including placebo. We employed ranking strategies to determine the most efficacious method using the surface under the cumulative ranking curve; a higher surface under the cumulative ranking curve value implied a more efficacious method. We assessed the following outcomes: time from intervention to delivery, cesarean delivery rates, changes in the Bishop score, need for additional ripening methods, incidence of Apgar scores <7 at 5 minutes, and uterine hyperstimulation. RESULTS: We included data from 42 randomized controlled trials including 6093 participants. When assessing the efficacy of all methods, 25 µg vaginal misoprostol was the most efficacious in reducing the time from intervention to delivery (surface under the cumulative ranking curve of 1.0) without increasing the odds of cesarean delivery, the need for additional ripening methods, the incidence of a low Apgar score, or uterine hyperstimulation. Acupressure (surface under the cumulative ranking curve of 0.3) and primrose oil (surface under the cumulative ranking curve of 0.2) were the least effective methods in reducing the time to delivery interval. Among effective methods, 50 mg oral mifepristone was associated with the lowest odds of cesarean delivery (surface under the cumulative ranking curve of 0.9). CONCLUSION: When balancing efficacy and safety, vaginal misoprostol 25 µg represents the best method for outpatient cervical ripening.

RESUMO

INTRODUCTION: Desmopressin (DDAVP) has been utilized clinically in patients taking aspirin (ASA) to improve drug-induced platelet dysfunction. Misoprostol and carboprost, prostaglandin analogs commonly used for postpartum hemorrhage, may also induce platelet aggregation. The aim of this study was to determine the effects of DDAVP, misoprostol, and carboprost administration on platelet aggregability following traumatic brain injury (TBI) in mice treated with ASA. METHODS: Male C57BL/6 mice were randomized into seven groups (n = 5 each): untouched, ASA only, Saline/TBI, ASA/TBI, ASA/TBI/DDAVP 0.4 µg/kg, ASA/TBI/misoprostol 1 mg/kg, and ASA/TBI/carboprost 100 µg/kg. TBI was induced via a weight drop model 4-h after ASA (50 mg/kg) gavage. Mice were given an intraperitoneal injection of DDAVP, misoprostol, or carboprost 10 minutes after TBI. In vivo testing was completed utilizing tail vein bleed. Mice were sacrificed 30-min posttreatment and blood was collected via cardiac puncture. Whole blood was analyzed via Multiplate impedance aggregometry, rotational thromboelastometry, and TEG6s. RESULTS: Mice receiving misoprostol after ASA/TBI demonstrated decreased tail vein bleeding times compared to ASA only treated mice. However, mice treated with misoprostol following ASA and TBI demonstrated decreased platelet aggregability compared to untouched mice and TBI only mice within the arachidonic acid agonist pathway. By contrast, DDAVP and carboprost did not significantly change platelet aggregability via adenosine diphosphate or arachidonic acid following ASA and TBI. However, DDAVP did decrease the platelet contribution to clot via rotational thromboelastometry. CONCLUSIONS: Reversal of medication-induced platelet inhibition has become increasingly controversial after TBI. Based on these results, DDAVP, misoprostol, nor carboprost consistently improve platelet aggregability following TBI in those also treated with ASA.

RESUMO

OBJECTIVES: To assess changes in the monthly numbers of hospital-based abortions and outpatient early medical abortions in Victoria during January 2012 - March 2022, with a particular interest in the impact of the coronavirus disease 2019 (COVID-19) pandemic. STUDY DESIGN: Population-based retrospective cohort study; time series analysis of Victorian Admitted Episodes Dataset (VAED) and Pharmaceutical Benefits Scheme (PBS) data. SETTING, PARTICIPANTS: All admitted care episodes in Victoria during 1 January 2012 - 31 March 2022 with medical abortion as the principal diagnosis; all PBS claims for mifepristone-misoprostol (MS-2 Step) during 1 January 2015 (date of listing) - 31 March 2022. MAIN OUTCOME MEASURES: Changes in monthly numbers (with 95% confidence intervals [CIs]) of admissions for hospital-based and outpatient early medical abortions during the pre-pandemic period (January 2012 - March 2020), the first full month of the COVID-19 pandemic (April 2020), and the pandemic period (May 2020 - March 2022). RESULTS: The monthly number of hospital-based abortions declined in Victoria during the pre-pandemic period (slope, -2.92 [95% CI, -3.45 to -2.38] per month); the rate of decline was greater during the pandemic period (slope, -5.74 [95% CI, -10.5 to -0.96] per month). The monthly number of outpatient early medical abortions increased during the pre-pandemic period (slope, 5.94 [95% CI, 5.34-6.34] per month); it declined during the first month of the pandemic (slope, -26.4 [95% CI, -70.1 to -17.3] per month), but did not significantly change thereafter. The total monthly number of abortions during the pandemic period did not deviate markedly from the pre-pandemic median value. The pre-pandemic declines in monthly numbers of abortions in major city hospitals, in private hospitals, or at earlier than 14 weeks' gestation intensified during the pandemic period. During January 2015 - March 2020, 14 634 of 103 496 abortions were outpatient medical abortions (14%); during the pandemic period, 11 154 of 33 056 abortions were outpatient medical abortions (33%). CONCLUSIONS: The use of outpatient early medical abortion has steadily increased in Victoria since the PBS listing of mifepristone-misoprostol, which helped ensure access to abortion during the COVID-19 pandemic. Outpatient medical abortions may eventually outnumber surgical early abortions in Victoria, but they are not always appropriate: hospitals will continue to be essential for comprehensive abortion care.

RESUMO

Importance: Induction of labor (IOL) is a common obstetric intervention. Augmentation of labor and active management of the second stage is frequently required in obstetric practice. However, techniques around labor and induction management vary widely. Evidence-based practice regarding induction and labor management can reduce birth complications such as infection and hemorrhage and decrease rates of cesarean delivery. Objective: To review existing evidence on IOL and labor management strategies with respect to preparing for induction, cervical ripening, induction and augmentation, and second stage of labor techniques. Evidence acquisition: Review of recent original research, review articles, and guidelines on IOL using PubMed (2000-2022). Results: Preinduction, pelvic floor training and perineal massage reduce postpartum urinary incontinence and perineal trauma, respectively. Timely membrane sweeping (38 weeks) can promote spontaneous labor and prevent postterm inductions. Outpatient Foley bulb placement in low-risk nulliparous patients with planned IOL reduces time to delivery. Inpatient Foley bulb use beyond 6 to 12 hours shows no benefit. When synthetic prostaglandins are indicated, vaginal misoprostol should be preferred. For nulliparous patients and those with obesity, oxytocin should be titrated using a high-dose protocol. Once cervical dilation is complete, pushing should begin immediately. Warm compresses and perineal massage decrease risk of perineal trauma. Conclusion and relevance: Several strategies exist to assist in successful IOL and promote vaginal delivery. Evidence-based strategies should be used to improve outcomes and decrease risk of complications and cesarean delivery. Recommendations should be shared across interdisciplinary team members, creating a model that promotes safe patient care.

RESUMO

Importance: Several medications have been used to achieve medical abortion in the first trimester of pregnancy. The most commonly used is the combination of mifepristone and misoprostol; however, different doses and routes of administration have been proposed. Objective: The aim of this study was to summarize published data on the effectiveness, adverse effects, and acceptability of the various combinations of mifepristone and misoprostol in medical abortion protocols in the first trimester of pregnancy. Evidence Acquisition: This was a comprehensive review, synthesizing the findings of the literature on the current use of mifepristone and misoprostol for first-trimester abortion. Results: The combination of mifepristone and misoprostol seems to be more effective than misoprostol alone. Regarding the dosages and routes, mifepristone is administered orally, and the optimal dose is 200 mg. The route of administration of misoprostol varies; the sublingual and buccal routes are more effective; however, the vaginal route (800 µg) is associated with fewer adverse effects. Finally, the acceptability rates did not differ significantly. Conclusions: Different schemes for first-trimester medical abortion have been described so far. Future research needs to focus on identifying the method that offers the best trade-off between efficacy and safety in first-trimester medical abortion.

RESUMO

BACKGROUND: Intrauterine foetal death (IUFD) is an unpleasant pregnancy outcome and prompt delivery of the dead foetus is usually desired by mothers. Unfortunately, spontaneous labour and delivery may not occur early and prolonged retention of the dead foetus in utero is life-threatening. Many of the agents currently used for the induction of labour may result in a prolonged delivery process. OBJECTIVES: To compare the efficacy and safety of mifepristone and misoprostol versus misoprostol alone for induction of labour in women with intrauterine foetal death. MATERIALS AND METHODS: This was a triple-blind randomized controlled trial. Eighty women were randomized into two groups. The intervention group received a single oral dose of 200 mg mifepristone, followed by 6-hourly 50 µg misoprostol vaginal insertion, after 24-hour intervals. The control group received a placebo, followed by 6-hourly 50 µg misoprostol vaginal insertion, after 24-hour intervals. The primary outcome measure was the induction to delivery interval. RESULTS: Maternal age, gestational age, parity and pre-induction bishop's score were comparable between the two groups. The mean induction to the delivery interval in the intervention group was significantly less in the intervention group than the control group (18.78 ± 6.51 hours versus 37.10 ± 10.10; P < 0.001). The total dose of misoprostol required for induction of labour; the need for oxytocin augmentation of labour; and the observed side effects of misoprostol were all significantly less in intervention group than control group (P < 0.001; P < 0.01; and P = 0.03, respectively). CONCLUSION: The combination of mifepristone and misoprostol has greater efficacy and better safety profile than the use of misoprostol alone for induction of labour. This combination should be considered when induction of labour is indicated for IUFD.

RESUMO

The UK is usually viewed as having liberal abortion regulations, providing good access to abortion care within a publicly funded health service. However, the underlying laws are authoritarian, dating from an era when public executions drew large crowds and 67 years before women were able to vote. Abortion is only legal when two doctors certify it meets the permitted grounds, and the penalty for self-managed abortion is up to life imprisonment for both the woman and any accomplice. These laws had prevented the use of mifepristone and misoprostol at home. Changes to the regulations for misoprostol in 2018 and mifepristone in 2020 permitted home use, but the government announced they were rescinding the approval for mifepristone in 2022. This article discusses how, despite the opposition of government, significant progressive changes to the abortion laws were achieved. Early medical abortion at home is now protected in law, and safe access zones protect patients and staff from harassment and intimidation from protesters. Despite this progress, increasing numbers of women are facing criminal investigation and face long prison sentences if convicted. The need for decriminalization and for abortion care to be regulated like all other health care is the next pressing issue.

RESUMO

BACKGROUND: Uterine prolapse is a rare complication of pregnancy, and there is still no consensus on the choice of delivery method. METHODS: The patient's reproductive history included an abortion and eutocic delivery of a girl weighing 3200 g; the current pregnancy was the third pregnancy. Her cervical region was outside the vaginal opening and was red in color, with evident enlargement (6 × 4 cm) and a broken surface. The cervical area also showed white discharge. According to her Transvaginal ultrasonography revealed a fetus in the uterine cavity at approximately 19 weeks of gestation. Gynecological examination revealed prolapse of both the anterior and posterior vaginal walls. Evaluation of the pelvic organ prolapse-Q scores showed that the patient had uterine prolapse at stage IV. RESULTS: Vaginal delivery was performed smoothly after oral administration mifepristone and misoprostol tablets for a few days, obtaining a dead female fetus in cephalic, 25 cm in length. The cervix of the pregnant woman did not prolapse during the delivery. CONCLUSION: For pregnancy with uterine prolapse and cervical incarceration, transvaginal delivery is a potential treatment option. Maintenance of cervical retraction and oral mifepristone administration with misoprostol tablets is crucial during this delivery. This treatment can minimize the risk of cervical lacerations and uterine rupture, helping surgeons to complete the operation successfully.

RESUMO

Telehealth abortion has become critical to addressing surges in demand in states where abortion remains legal but evidence on its effectiveness and safety is limited. California Home Abortion by Telehealth (CHAT) is a prospective study that follows pregnant people who obtained medication abortion via telehealth from three virtual clinics operating in 20 states and Washington, DC between April 2021 and January 2022. Individuals were screened using a standardized no-test protocol, primarily relying on their medical history to assess medical eligibility. We assessed effectiveness, defined as complete abortion after 200 mg mifepristone and 1,600 µg misoprostol (or lower) without additional intervention; safety was measured by the absence of serious adverse events. We estimated rates using multivariable logistic regression and multiple imputation to account for missing data. Among 6,034 abortions, 97.7% (95% confidence interval (CI) = 97.2-98.1%) were complete without subsequent known intervention or ongoing pregnancy after the initial treatment. Overall, 99.8% (99.6-99.9%) of abortions were not followed by serious adverse events. In total, 0.25% of patients experienced a serious abortion-related adverse event, 0.16% were treated for an ectopic pregnancy and 1.3% abortions were followed by emergency department visits. There were no differences in effectiveness or safety between synchronous and asynchronous models of care. Telehealth medication abortion is effective, safe and comparable to published rates of in-person medication abortion care.

RESUMO

OBJECTIVE: One of the most critical reasons for limiting cancer treatment is the toxic effects of anti-cancer drugs on healthy tissues and organs. This study aims to investigate the possible protective effects of misoprostol (MS) against the damage that arises from paclitaxel (PT), an anti-cancer pharmacological agent, in the rat heart using histopathological and biochemical analyses. METHODS: In this study, four groups, each containing seven animals, were formed by random selection from 28 Sprague Dawley female rats. Control group rats were administered 1 ml of normal saline orally and intraperitoneally (i.p.) for six days. While the PT group rats were administered PT at a dose of 2 mg/kg intraperitoneally (i.p.) on days 0, 2, 4, and 6, the MS group was administered MS at a dose of 0.2 mg/kg in 1 ml normal saline by oral gavage for six days. PT and MS were administered to the PT + MS group rats in the same dose and route as the previous groups. RESULTS: Administration of PT increased serum lactate dehydrogenase (LDH), cardiac troponin I (cTn-I), creatine kinase isoenzyme MB (CK-MB), and brain natriuretic peptide (BNP) levels. PT administration also decreased the levels of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) in the heart tissue while increasing the level of malondialdehyde (MDA) (p < 0.05). In histopathological examinations, pathological changes, such as edema, congestion, hemorrhage, apoptosis, and degeneration, occurred in the heart tissue of PT-treated rats. The negative changes in histopathological and biochemical parameters that occurred in the PT group were almost not observed in the PT + MS group (p < 0.005). CONCLUSION: When the findings were evaluated, it was concluded that MS protects the heart tissue from the harmful effects of PT, probably due to its antioxidant, anti-apoptotic and TNF-alpha suppressive effects.
