    The optimal dose of misoprostol for the induction of labour remains uncertain. To compare the efficacy and safety of 25 versus 50 micrograms of intravaginal misoprostol tablets for the induction of labour and cervical ripening. We performed electronic and manual searches to identify relevant randomised trials. The efficacy outcomes assessed were rates of vaginal delivery within 24 hours, delivery within one dose, and oxytocin augmentation, and interval to delivery. The safety outcomes assessed were incidences of tachysystole, hyperstimulation, caesarean delivery, cesarean delivery for non-reassuring fetal heart rate (FHR), operative vaginal delivery, abnormal 5-minute Apgar score, abnormal cord gas values, admission to a neonatal intensive care unit (NICU), and meconium passage. Thirteen studies (1945 women) were included. Relative risk (RR) and 95% confidence intervals (CI) were calculated using fixed-effects and random-effects models. We found that 25 micrograms was less efficacious, with lower rates of delivery after one dose (RR 0.59; 95% CI 0.39-0.88) and vaginal delivery within 24 hours (RR 0.88; 95% CI 0.79-0.96), and with increased rates of oxytocin augmentation (RR 1.54, 95% CI 1.36-1.75). We noted an improved safety profile with 25 micrograms, however, with decreased rates of tachysystole (RR 0.46; 95% CI 0.35-0.61), hyperstimulation (RR 0.5; 95% CI 0.31-0.78), caesarean deliveries for non-reassuring FHR (RR 0.67; 95% CI 0.52-0.87), NICU admissions (RR 0.63; 95% CI 0.4-0.98), and meconium passage (RR 0.65; 95% CI 0.45-0.96). Although 50 micrograms of intravaginal misoprostol may be more efficacious, safety concerns make the 25-microgram dose preferable. © 2014 Royal College of Obstetricians and Gynaecologists.

    Full Text Available Objectives. To compare the efficacy and safety of intravaginal misoprostol with transcervical Foley catheter for labour induction. Material and Methods. One hundred and four women with term gestation, with Bishop score < 4, and with various indications for labour induction were randomly divided into two groups. In Group I, 25 μg of misoprostol tablet was placed intravaginally, 4 hourly up to maximum 6 doses. In Group II, Foley catheter 16F was placed through the internal os of the cervix under aseptic condition and then inflated with 50 cc of sterile saline. Statistical analysis was done using SPSS software. Results. The induction to delivery interval was 14.03 ± 7.61 hours versus 18.40 ± 8.02 hours (p<0.01. The rate of vaginal delivery was 76.7% versus 56.8% in misoprostol and transcervical Foley catheter group, respectively. Uterine hyperstimulation was more common with misoprostol. Neonatal outcome was similar in both the groups. Conclusion. Intravaginal misoprostol is associated with a shorter induction to delivery interval as compared to Foley’s catheter and it increases the rate of vaginal delivery in cases of unripe cervix at term. Transcervical Foley catheter is associated with a lower incidence of uterine hyperstimulation during labour.

Group B 400 mcg of misoprostol placed intravaginally every 4 hours for maximum 4 doses for termination. In both the above-mentioned groups, T. mifepristone 600 mg was given orally 36-48 hrs. prior to termination. RESULTS The mean induction abortion interval was significantly less (7 hrs. 36 mins in Group A compared with group B (9 hrs. 55 min. There was no statistical significant difference in the amount of mean dose used in both groups. The complete abortion rate within 48 hrs. in Group A was 94%, which shows no statistical significance when compared with Group B complete abortion rates (80%. However, it is interpreted that on adding ISMN, the number of complete abortion rates are higher. There was no failure of abortion in both the groups. The side effects such as pain abdomen and fever were less in Group A (38% when compared to Group B (78%. CONCLUSION Vaginally administered ISMN seems to be safe and effective method in second trimester pregnancy termination. There is a reduction in hospital stay, manpower, economy spent on patient, and a sense of wellbeing from the patient also.

    Full Text Available Peptic mucus synthesize especially prostaglandine E2 and I2. Prostaglandine E2 and I2 can impede acid secrete and stimulate mucus and bicarbonate secretion. Misoprostof, a synthetic methyl ester analogue of prostaglandin is both a powerful inhibitor of gastric secretion and is able to protect the gastroduodenal mucosa from damage. Misoprostol and other prostaglandine derivatives can be alternative drug of peptic ulcer relapse because the metyl ester of prostaglandin exert an antisecretion and protective effects on peptic mucus. The clinical effectiveness of misoprostol is comparable to cimethidin in short term treatment of peptic and duodenum ulcer as well as reducing duodenal ulcer relapse. Misoprostol may prevent gastrointestinal and peptic ulcer in long term treatment of Non Steroid Anti Jnflamation Drug. The side effect of misoprostol is cervix maturation and uterotonic.

    Full Text Available Background: The success of labor induction is extremely dependent on the state of the cervix. There are various methods available in modern obstetrics practice for ripening the cervix, such as intravaginal prostaglandins and mechanical devices like transcervical catheters. Although plenty of studies have already compared the two methods for the unripened cervices, more studies are warranted in nulliparous patients only. This study aimed to compare the efficacy of intravaginal misoprostol tablets with transcervical Foley catheter for cervical ripening in nulliparous patients. Methods & Materials: In this randomized clinical trial, 120 nulliparous candidates for labor induction were recruited from two teaching centers in Tabriz within a 17-month period of time. All the enrolled cases had a live singleton fetus with cephalic presentation at term (≥37 weeks, on-admission Bishop Score≤4, intact membranes and reactive non-stress test results. They were randomly assigned to two equal age-matched groups receiving either intravaginal misoprostol (25 microgram, n=59, or transcervical insertion of 16F Foley catheter (n=60. Results: One time successful induction (i.e. successful induction after a single insertion of misoprostol, or expulsion of transcervical Foley catheter within 12 h of insertion was achieved in all the patients without employment of other methods such as use of syntocinon. Misoprostol was more effective in terms of induction-to-cervical ripening interval (15.16±3.59 h vs. 18.30±1.59 h; p<0.001. Tachysystole, on the other hand, was significantly more frequent in the misoprostol receivers (25.4% vs. 0%; p<0.001. The two groups were comparable for the rate of cesarean section (misoprostol, 37.3%; Folly catheter, 30%; p=0.40. Comparing the two groups, there was no significant difference with regard to change in Bishop Score (misoprostol, 1.90±0.54 h-1; Folly catheter, 1.89±0.74 h-1; p=0.95 and miscellaneous pregnancy-related and fetal

    To determine the effectiveness of 50 micro g misoprostol for midtrimester termination of pregnancies. The study subjects were 54 pregnant women admitted during the 2nd trimester (14-26 weeks) of gestation, willing or requiring termination of pregnancy. Those patients were included in the study who were admitted with closed cervical os, either had intrauterine death, fetal anomaly, medical disorder (hypertension or diabetes) or history of previous ceasrean section. Cases of placenta previa, acute asthma, glaucoma, cardiac diseases and allergy to prostaglandins were excluded. Each patient received 50 micro g misoprostol intravaginally. Maximum 4 doses were given at 4 hours interval and state of cervical os was assessed by vaginal examination before insertion of next dose or at the onset of uterine contractions. After 4 doses of misoprostol, patients were kept under observation and watched for uterine contractions to start or for expulsion of products. Syntocinon infusion was started to augment labour where products of conception failed to expel out inspite of open os. Outcome measures include success rate of termination within 12, 24, 36 and 48 hours, mean induction - abortion time interval and maternal side effects. Results: The success rate of termination within 12, 24, 36 and 48 hours were 27.7%, 83.3%, 94.4% and 96.3% respectively. Mean induction to abortion time interval, in case of abortion within 48 hours, was found to be 18.9 +- 11.58 (range 4-48 hours). Dead fetuses were aborted earlier than alive fetuses. The mean induction abortion time interval was 17.01+-8.7 hours in dead and 23.4 +- 15.9 hours in alive fetuses (t -value:1.9, p: 0.05). Two patients failed to deliver within 48 hours of induction. Two patients suffered from febrile illness. Vaginal administration of 50 micro g misoprostol every 4 hourly is an effective and safe agent for ripening of cervix and convenient way of inducing abortion during 2nd trimester of pregnancy in a women either with

    Full Text Available This paper is focused in some aspects of maternal exposure to misoprostol during perinatal period, and the abortive and teratogenesis effects on the fetus. The causes of malformations were revised, taking into account chemical, physical and environmental factors as well as the interaction between them. There are evidences that the practice of abortion tripled in Southern and Northeastern Brazil in 15 years, and one of the most frequent forms of abortion is through the use of misoprostol. In Brazil, 1991, 288,700 women were hospitalized as a consequence of complications induced by abortion attempt with this medicine. This fact resulted in the ban of misoprostol across our country, by Decree 344/98 determined by the Health Ministry. The use of misoprostol requires special control and it is allowed only in hospitals, with supervision of the municipal health surveillance. Among the more severe problems affecting the non-aborted child is the injury on the central nervous system, which frequently results in the Moebius syndrome. This is a congenital and non-progressive paralysis of the VI and VII cranial nerves, frequently bilateral, which produces a unexpressive facial appearance and convergent Strabismus. Even banned in our country, abortion is illegally practiced, being deprived of proper knowledge about misoprostol teratogenic effects on the fetus as well as the risks involving mothers.Este trabalho enfoca aspectos relativos à exposição ao misoprostol no período perinatal como abortificante e agente teratogênico, assim como as causas das malformações, considerando-se fatores químicos, físicos e ambientais.

    Full Text Available Context: Intrauterine fetal death (IUFD causes emotional distress and could result in intrauterine infection. In view of these complications, medical induction is recommended, if it is safe. Aim: The aim of this study was to compare the efficacy and safety of a combination of mifepristone and misoprostol with oral misoprostol alone for induction of labor in IUFD. Settings and Design: This is a randomized placebo-controlled trial conducted at a tertiary care teaching hospital in southern India. Patients and Methods: We recruited 72 women with IUFD in a singleton pregnancy after 28 weeks with intact membranes. Thirty-six women received oral placebo followed by misoprostol. In other group, 36 women received 200 mg oral mifepristone followed by misoprostol (both groups received 50 μg orally 4th hourly up to 5 doses. The interval between mifepristone/placebo and the first dose of misoprostol was 24 h. Results: Successful delivery occurred within 72 h in 31 of 36 (86% women who received mifepristone before misoprostol and in 28 of 36 (78% women who received only misoprostol (P = 0.541. Median (interquartile range induction to delivery interval was 3.5 (2–5 and 4 (3–5 h in the combination group and misoprostol group, respectively (P = 0.465. Conclusions: Addition of mifepristone to misoprostol appears to be marginally more effective than misoprostol alone for induction of labor in intermediate and late IUFD, although the differences were not statistically significant.

    Full Text Available BACKGROUND Termination of pregnancy in second trimester continues to be a challenge in developing countries especially in rural areas. There is an exponential rise in complications of abortion along with advancing gestational age. The search is on for an ideal method of abortion, which is reliable, safe and cheap. This study was conducted in M.K.C.G. Medical College and Hospital, Berhampur, from November 2015 to October 2017 with the aim of finding an effective method to induce second trimester abortion within reasonable time with fewer complications. MATERIALS AND METHODS A total of 80 patients were studied to compare combination of mifepristone and misoprostol (30 patients with single drug misoprostol alone (50 patients for second trimester abortion. The Induction Abortion Interval (IAI, success rate, misoprostol dose requirement and side effects with demographic characteristics were compared between the two groups. RESULTS There was a significant difference in the IAI in both the groups. The mean IAI was 562.218 minutes in study group, whereas in control group, IAI was 922.698 minutes. The success rate (complete abortion was 92.5% in study group and 68.4% in control group, and this was statistically significant. Misoprostol dose requirement (average in study group was 1081.48 μg and in control group was 1675.67 μg. More side effects were observed in the control group. CONCLUSION Mifepristone followed by misoprostol was more effective than misoprostol alone as it had a shorter IAI, better success rate, less requirement of misoprostol and fewer side effects.

    To evaluate the introduction of an early medical abortion program with methotrexate and misoprostol, using a standardized protocol. A total of 1973 women at 34 Planned Parenthood sites participated in a case series of early medical abortion. Ultrasound was used to confirm gestational age of less than 49 days from the first day of the last menstrual period. Women were given intramuscular methotrexate 50 mg/m(2) of body surface area on day 1, and then they inserted misoprostol 800 microg vaginally at home on day 5, 6, or 7. Women were advised to have a suction curettage if the pregnancy appeared viable 2 weeks after methotrexate or if any gestational sac persisted 4 weeks after methotrexate. Outcomes were complete medical abortion and suction curettage. Sixteen hundred fifty-nine women (84.1%) had a complete medical abortion, and 257 (13.0%) had suction curettage. The most common reason for curettage was patient option (8.9%). At 2 weeks after methotrexate use, 1.4% of women had curettage because of a viable pregnancy; at 4 weeks, 1.6% of women had curettage because of a persistent but nonviable pregnancy. One percent of women had curettage because of physician recommendation, most commonly for bleeding. Suction curettage rates decreased with site experience (P <.006) and were lower at early gestational ages (P <.004) and in nulliparous women (P <.004). Medical abortion with methotrexate and misoprostol is safe and effective and can be offered in a community setting.

    Recently the incidence of intravaginal ejaculatory dysfunction is increasing among infertile couples in Japan. Some unusual ways of masturbation and psychogenic issues were reported to cause this disorder. Patients, who had done masturbation in an unusual way for long time since their adolescence, were difficult to gain normal intravaginal ejaculation by the behavior therapy which was used for erectile dysfunction. We, therefore, used a masturbation aid (TENGA) for rehabilitation of ejaculation to overcome this condition. From January, 2010 through March, 2011, a total of 16 patients with intravaginal ejaculatory dysfunction underwent rehabilitation of ejaculation using TENGA. Patients' satisfaction and achievement of intravaginal ejaculation were evaluated by the questionnaire. Twelve patients (75%) could ejaculate in the masturbation aid (TENGA). Five patients (31%) succeeded to ejaculate in the partner's vagina after rehabilitation. A masturbation aid (TENGA) was a useful tool to correct the way of masturbation and achieve normal intravaginal ejaculation. This masturbation aid can be one of the effective options for the treatment of intravaginal ejaculatory dysfunction.

    Radiation mucositis is a major acute toxicity of radiation therapy for head and neck malignancies. We tested whether Misoprostol, a synthetic prostaglandin E 1 analogue given prophylactically decreased intensity of radiation mucositis. A double blind randomized trial was conducted. The intervention consisted of swishing dissolved drug or placebo as a mouthwash, and then swallowing two hours prior to radiation treatment. Patients were stratified based on concurrent chemotherapy, altered fractionation, smoking, extent of oral mucosa in radiation field, and institution. The main end point was the extent of RTOG grade III mucositis, taking into account both time and duration of mucositis. 42 patients were randomized to active drug, and 41 patients to placebo. The trial was designed to have 70 patients in each arm. The trial closed due to poor accrual. In the Misoprostol group 18/42 (43%) had grade III/IV mucositis, and in the placebo group 17/40 (42%). The mean difference between the areas under the curve was 0.38 (p-value: 0.38). For grade II mucositis the corresponding figures were 18 (42%) and 19 (47%). The time from commencement of radiation therapy to the development of peak mucositis was 49 days in the misoprostol patients and 51 days in the placebo group. The duration of grade III mucositis 12.5 days in the Misoprostol patients and 7 days in the placebo patients. In the Misoprostol arm 4 patients had an interruption to their Radiation Therapy, in the Placebo arm 5 had interruptions. Patients average weight loss was 8.1 and 8.2kg. Average self-assessment was via a 10cm LASA scale for soreness of throat and overall well-being. Misoprostol showed a worse QoL on soreness of mouth (mean difference: 0.84 units (p-value .03), but overall well-being was similar on both treatment arms 1 patient withdrew in the Misoprostol arm and 2 in the placebo arm. Misoprostol given prophylactically does not reduce the incidence of Grade III/IV mucositis, is associated with a shorter

    To show the advantages of the use of vaginal misoprostol, a prostaglandine E1 analogue, in the prevention of the post-partum haemorrhage. This was a prospective, observational, comparative study. The study included 400 patients with high risk of postpartum haemorrhage at our center between January 1999 and may 2001. Patients were divided in two groups. In group I (208 patients) misoprostol was used in a dose of 800 ugr and in group II (192 patients) in whom misoprostol was not used. Both groups were treated initially with our conventional oxytocin protocol. We evaluated the use of additional oxytocin or ergotamine, haemoglobin levels pre and post-partum, the amount of blood loss, and the need for blood transfusion or hysterectomy. The need for additional oxytocin or ergotamine was reduced to less than 10% in group I when compared to group II; the drop in haemoglobin levels and the amount of blood loss were also less in group I (p: 0.03). In this group only one patient needed for blood transfusion and no patient needed hysterectomy. In group II six patients need a blood transfusion and there was the need for two hysterectomies. The use of vaginal misoprostol is effective to control the postpartum bleeding, reducing the blood loss after birth in women with high risk of post-partum haemorrhage as well as the need for blood transfusion. It's use has mild side effects and is of low cost.

    Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls. Case group received daily oral dose of 10mg letrozole for three days followed by vaginal misoprostol. In control group the patients received only vaginal misoprostol. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed. Complete abortion was observed in 30 patients (76.9%) in case group and 9 (23.1%) cases were failed. In control group there was 16 (41.03%) complete abortions and 23 (58.97%) cases were failed to abort. Patients with gestational age of between 6 and 10 weeks did not show significant difference in both groups (P=0.134). Regarding pregnancy remnants there were significant differences between two groups (P=0.034). The time form admission to discharge in case groups were significantly shorter than those in control group (P=0.001). The indication for curettage in case group was significantly less than control group (P=0.001). A 3-day course of letrozole (10mg/daily) followed by misoprostol was associated with a higher complete abortion and lower curettage rates and reduction in time from admission to discharge in women with gestational age ≤14 weeks compared to misoprostol alone.

    Bangladesh is one of the few countries that may actually achieve the fifth Millennium Development Goal (MDG) in time, despite skilled birth attendance remaining low. The purpose of this paper is to examine the potential role misoprostol can play in the decline of maternal deaths attributed to postpartum hemorrhage (PPH) in Bangladesh. Using data from a misoprostol and blood loss measurement tool feasibility study in Bangladesh, observed cause specific maternal mortality ratios (MMRs) were estimated and contrasted with expected ratios using estimates from the Bangladesh Maternal Mortality Survey (BMMS) data. Using Crystal Ball 7 we employ Monte Carlo simulation techniques to estimate maternal deaths in four scenarios, each with different levels of misoprostol coverage. These scenarios include project level misoprostol coverage (69%), no (0%), low (40%), and high (80%) misoprostol coverage. Data on receipt of clean delivery kit, use of misoprostol, experience of PPH, and cause of death were used in model assumptions. Using project level misoprostol coverage (69%), the mean number of PPH deaths expected was 40 (standard deviation = 8.01) per 100,000 live births. Assuming no misoprostol coverage (0%), the mean number of PPH deaths expected was 51 (standard deviation = 9.30) per 100,000 live births. For low misoprostol coverage (40%), the mean number of PPH deaths expected was 45 (standard deviation = 8.26) per 100,000 live births, and for high misoprostol coverage (80%), the mean number of PPH deaths expected was 38 (standard deviation = 7.04) per 100,000 live births. This theoretical exercise hypothesizes that prophylactic use of misoprostol at home births may contribute to a reduction in the risk of death due to PPH, in addition to reducing the incidence of PPH. If findings from this modeling exercise are accurate and uterotonics can prevent maternal death, misoprostol could be the tool countries need to further reduce maternal mortality at home births.

  2. How often and under which circumstances do Mexican pharmacy vendors recommend misoprostol to induce an abortion?

    Misoprostol was used by women across Mexico to induce abortion even before 2007, when first-trimester abortion was legalized in Mexico City. Pharmacy vendors' misoprostol recommendation practices across subregions of Mexico after abortion legalization warrant examination. Overall, 192 pharmacies in four regions of Mexico were randomly selected and visited by simulated clients presenting three scenarios (a young woman, an adult woman and a male partner). Bivariate and multivariate analyses were used to explore associations between pharmacy, vendor and client characteristics and drug access. In 558 encounters with simulated clients, 78% of vendors provided information about misoprostol-18% recommended it spontaneously and 60% recommended it only after the client asked specifically for the drug. Fifteen percent of vendors recommended a potentially effective misoprostol dosing regimen. Mexico City-based pharmacies and those in the Central region were significantly less likely than those in the North region to require a prescription to sell misoprostol (odds ratios, 0.2 and 0.3, respectively). Independent pharmacies and those from low-?income areas were significantly more likely to sell misoprostol by the pill than chain pharmacies and those in medium-income areas (3.2 and 2.7, respectively). Access to misoprostol is influenced by neighborhood socioeconomic level, pharmacy location and pharmacy type. The frequently inaccurate and incomplete information provided to clients about using misoprostol for abortion suggests the need to improve pharmacy vendor training in medication abortion options and to develop ways to directly inform women about misoprostol use.

    Full Text Available Background: Induction of labour is common in obstetric practice. We conducted this study to find the appropriate and safe drug for labour induction and to compare the safety and efficacy of oral misoprostol and vaginal dinoprostone for labour induction. Methods: In a provisional, prospective and cross-sectional study, one hundred and fifty five singleton cephalic presentation full term pregnancies with medical or obstetric indication for labour induction were allocated in two groups. First group received oral 50 micrograms for nulliparas and low parity group (1-4, and 25micrograms for grand multiparas (≥ 5 misoprostol orally every 6 hours to a maximum of four doses daily. In the second group vaginal tablets of dinoprostone 3mg then 1.5mg for nulliparas and 1.5mg for low parity and grand multiparas groups were inserted in the posterior fornix, every 8 hours. Primary outcome measures were: induction success, induction-delivery interval and number of used doses. Secondary outcome measures included: maternal side effects, caesarean section rate, mode of delivery and neonatal outcome. Data was collected from patient case notes and analyzed using software SPSS (version 13.0 and p-value < 0.05 was used as statistical significance of differences. Results: In our study there were no significant differences in baseline parameters in the two groups nor in the indications for labor induction except misoprostol was used in premature rupture of membrane. Induction of labor succeeded in 123 (79.35% women without other interventions from other methods (80.26%misoprostol group versus 78.5% dinoprostone p=0.492. It was observed that there were no significant differences between the two groups in final outcomes nor in obstetrical complications. There was no significance in differences between misoprostol and dinoprostone groups in induction-delivery interval (15.2 ± 14.5 hours versus 16.4 ± 11.3 hours p=0.6 resp.. Conclusions: This study demonstrated that oral

    Objective: To determine the efficacy of rectal misoprostol in management of Post Partum Haemorrhage in third stage of labour. Study Design: Interventional study. Place and Duration of Study: Gynaecology and obstetrics department at PNS Shifa Hospital Karachi, from Sep 2012 to Mar 2013. Material and Methods: All singleton and multiple pregnancies of gestation 37-42 weeks, who presented in labour room to deliver and had prolonged second stage of labour (n=112) were enrolled in the study. Patients, who were having coagulopathy, abruption, placenta previa, and allergy to prostaglandins were excluded from the study. Third stage was managed actively according to hospital standard routine. Hemoglobin was measured at the time of admission and repeated after delivery in patients having PPH. Blood was estimated by weighing all gauzes and packs. If blood loss more than 500ml one hour after delivery and all traumatic causes and retained placenta were excluded, 600 mu g (3 tablets) of misoprostol were given per rectally, which were inserted up to a digit depth. After one hour total amount of blood loss was calculated. The data were then entered in a proforma and analyzed. Results: Majority (44.6%) of the women were 26-33 years of age, 8.9% had PPH with fall in hemoglobin by 1.5-2 gms/dl. Ninety percent of the patients responded to rectal misoprostol. Conclusion: Active management of third stage of labour has a definite role in the preventive of PPH. Rectal administration of misoprostol should be considered for control of PPH in low resource settings like ours as it was found effective in the study. (author)

    Objective was to assess the effectiveness of misoprostol in cervical ripening before evacuation of conception in the first trimester missed miscarriages and to compare between oral and vaginal routes of administration. A randomized control study was carried out in Baghdad Teaching Hospital, Baghdad, Iraq in 2006. One hundred and twenty women with first fist trimester missed miscarriages were divided into 2 study groups, randomized for oral and vaginal (400 mcg) misoprostol priming of cervix and 2 control groups randomized for oral and vaginal placebo, before undergoing surgical evacuation of conception after 3 hours. Measured outcomes were: post medication cervical dilatation, time needed to dilate the cervix surgically, blood loss and developments of the side effects of misoprostol. Post medication cervical dilation was higher in the misoprostol group (7.07+-1.36 mm for oral misoprostol, 7.77+-1.22 mm for vaginal misoprostol), versus the control groups (2.43+-0.5 mm). Post medication cervical dilatation was significantly higher in the vaginal misoprostol group, compared to the oral group (p=0.04). The time required to dilate the cervix in the misoprostol group was shorter, compared with placebo. There were no significant differences in the amount of blood loss between oral (p=0.074) and vaginal misoprostol groups (p=0.62) and gastrointestinal side effects were significantly more in the oral misoprostol group (p=0.014). Misoprostol is an effective cervical priming agent when administered either orally or vaginally before evacuation of conception in the termination of the first trimester missed miscarriage. (author)

    Making misoprostol widely available for management of postpartum haemorrhage (PPH) and post abortion care (PAC) is essential for reducing maternal mortality. Private pharmacies (thereafter called "pharmacies") are integral in supplying medications to the general public in Senegal. In the case of misoprostol, pharmacies are also the main supplier to public providers and therefore have a key role in increasing its availability. This study seeks to understand knowledge and provision of misoprostol among pharmacy workers in Dakar, Senegal. A cross-sectional survey was conducted in Dakar, Senegal. 110 pharmacy workers were interviewed face-to-face to collect information on their knowledge and practice relating to the provision of misoprostol. There are low levels of knowledge about misoprostol uses, registration status, treatment regimens and side effects among pharmacy workers, and corresponding low levels of training on its uses for reproductive health. Provision of misoprostol was low; of the 72% (n = 79) of pharmacy workers who had heard of the product, 35% (n = 27) reported selling it, though rarely for reproductive health indications. Almost half (49%, n = 25) of the respondents who did not sell misoprostol expressed willingness to do so. The main reasons pharmacy workers gave for not selling the product included stock outs (due to product unavailability from the supplier), perceived lack of demand and unwillingness to stock an abortifacient. Knowledge and availability of misoprostol in pharmacies in Senegal is low, posing potential challenges for delivery of post-abortion care and obstetric care. Training is required to address low levels of knowledge of misoprostol registration and uses among pharmacy workers. Barriers that prevent pharmacy workers from stocking misoprostol, including weaknesses in the supply chain and stigmatisation of the product must be addressed. Low reported sales for reproductive health indications also suggest limited prescribing of

    The effect of 200 micrograms misoprostol (a synthetic prostaglandin E1 analogue) on food stimulated intragastric acidity has been monitored over a 9 h period in 16 normal volunteers. Misoprostol caused a significant inhibition of intragastric acidity for 2 h post-dosing, but no significant effect was seen thereafter on either basal or food stimulated acidity.

  8. The use of misoprostol in termination of second-trimester pregnancy

    Full Text Available Misoprostol, a synthetic prostaglandin E1 analog, is initially used to prevent peptic ulcer. The initial US Food and Drug Administration-approved indication in the product labeling is the treatment and prevention of intestinal ulcer disease resulting from nonsteroidal anti-inflammatory drugs use. In recent two decades, misoprostol has approved to be an effective agent for termination of pregnancy in various gestation, cervical ripening, labor induction in term pregnancy, and possible management of postpartum hemorrhage. For the termination of second-trimester pregnancy using the combination of mifepristone and misoprostol seems to have the highest efficacy and the shortest time interval of abortion. When mifepristone is not available, misoprostol alone is a good alternative. Misoprostol, 400 μg given vaginally every 3–6 hours, is probably the optimal regimen for second-trimester abortion. More than 800 μg of misoprostol is likely to have more side effects, especially diarrhea. Although misoprostol can be used in women with scarred uterus for termination of second-trimester pregnancy, it is recommended that women with a scarred uterus should receive lower doses and do not double the dose if there is no initial response. It is also important for us to recognize the associated teratogenic effects of misoprostol and thorough consultation before prescribing this medication to patients regarding these risks, especially when failure of abortion occurs, is needed.

    To assess knowledge of, and intentions to use misoprostol to preventing postpartum hemorrhage by women in a pastoralist community of the Somali Region of Ethiopia. A cross-sectional study enrolled women aged 15-49years living in Adadle district, Ethiopia, between April 26 and May 3, 2012. A structured questionnaire was used to collect data on participants' knowledge of misoprostol and if they had any intention to use it in the future. Participants also detailed their preferred healthcare provider for administering misoprostol. A total of 829 women were enrolled in the study. Among the participants, 42 (5.1%) had knowledge of misoprostol and 302 (36.4%) described themselves as being willing to use misoprostol in the future. Among respondents who were willing to use misoprostol in the future, traditional birth attendants were the preferred healthcare practitioners to administer it. Awareness of misoprostol was low in the study sample but willingness to use the drug was somewhat higher. Raising awareness and knowledge among communities and traditional birth attendants regarding the advantages of misoprostol is crucial to enhance uptake and reduce the incidence of postpartum hemorrhage.

    Objectives: To compare oral misoprostol versus intramuscular oxytocin in the management of third stage of labour. Methods: The quasi-experimental study was conducted at the Obstetrics and Gynaecology Unit II, Civil Hospital, Karachi, from June 20 to December 19, 2006. A total of 70 patients diagnosed in active phase of labour who fulfilled the inclusion criteria were selected by non-probability convenience sampling. These patients were divided into 2 groups of 35 patients each, for Oxytocin (Group 1) and misoprostol (Group 2). Main and secondary outcome measures were analysed. SPSS 10 was used for statistical analysis. Results: Average amount of blood loss(ml) was 267.14+-140.35 with Oxytocin versus 302.86+-160.4, with Misoprostol, this difference was statistically insignificant (p=0.236). Average drop in haemoglobin concentration (g/dl) with Oxytocin was 1.55+-0.38 vs 1.66+-0.61 with Misoprostol (p=0.684). Drop in haematocrit (%) was 4.18+-0.64 with Oxytocin vs. 4.50+-0.92 with Misoprostol (p=0.133). There was also insignificant difference in duration of third stage of labour, between oxytocin and Misoprostol groups (5.37+-2.20 vs. 5.23+-2.46, p=0.451) Shivering, in Misoprostol group occured in n=11 (31.4%) vs n=3 (8.6%) with Oxytocin (p=0.017) and pyrexia in n=6 (17.1%) with misoprostol vs n=0, with oxytocin (p=0.025) thus significantly higher in misoprostol group. Conclusion: There were no major differences in oral misoprostol and intramuscular oxytocin in the management of third stage of labour. (author)

    To compare the efficacy and safety of mifepristone followed by misoprostol with misoprostol alone in the management of early pregnancy failure (EPF). A randomized double-blind placebo-controlled clinical trial. Ninety-two women with EPF ≤12 weeks were recruited and randomly allocated to receive either mifepristone 200 mg ( n  = 46) or placebo ( n  = 46). Forty-eight hours later, patients in both the groups were given 800 µg misoprostol per-vaginum. If no expulsion occurred within 4 h, repeat doses of 400 µg misoprostol were given orally at 3-hourly interval to a maximum of 2 doses in women ≤9 weeks by scan and 4 doses in women >9 weeks by scan. Pre-treatment of misoprostol with mifepristone significantly increased the complete abortion rate (86.7 vs. 57.8%, p  = 0.009) and, hence, reduced the need for surgical evacuation (13.3 vs. 42.2%, p  = 0.002), induction to expulsion interval (4.74 ± 2.24 vs. 8.03 ± 2.77 h, p  = 0.000), mean number of additional doses of misoprostol required (0.68 vs. 1.91, p  = 0.000), and side effects. Use of mifepristone prior to misoprostol in EPF significantly improves the efficacy and reduces the side effects of misoprostol alone.

    Full Text Available Introduction Möbius syndrome (MS; VI and VII palsy is a rare disease that in Brazil has a great frequency because of the use of misoprostol during pregnancy. Objective Verify if the speech and language performance of children with MS whose mothers reported use of misoprostol (Cytotec, Pfizer, Connecticut, USA are different from the performance of children of mothers who did not report use. Methods The stomatognathic system beyond receptive and expressive language and speech was evaluated in children with MS, and their mothers were questioned whether they used misoprostol during the pregnancy. Results During the interview, 61.11% of mothers reported that they took misoprostol during the pregnancy. Most of the subjects (83.3% whose mothers took misoprostol presented bilateral palsy beyond bad mobility of the tongue (90.9% and speech disorders (63.6%. Conclusion The number of mothers who took misoprostol without knowing the risk for MS was great. The lack of facial expressions and speech disorders were common characteristics of the individuals with MS, whether the mothers took misoprostol during the pregnancy or not.

    Sublingual misoprostol produces a rapid peak concentration, and is more effective than oral administration. We compared the postpartum measured blood loss with 400 μg powdered sublingual misoprostol and after standard care using 10 iu intramuscular (IM) oxytocin. Double-blind randomised controlled trial. A teaching hospital: J N Medical College, Belgaum, India. A cohort of 652 consenting eligible pregnant women admitted to the labour room. Subjects were assigned to receive the study medications and placebos within 1 minute of clamping and cutting the cord by computer-generated randomisation. Chi-square and bootstrapped Student's t-tests were used to test categorical and continuous outcomes, respectively. Measured mean postpartum blood loss and haemorrhage (PPH, loss ≥ 500 ml), >10% pre- to post-partum decline in haemoglobin, and reported side effects. The mean blood loss with sublingual misoprostol was 192 ± 124 ml (n=321) and 366 ± 136 ml with oxytocin IM (n=331, P ≤ 0.001). The incidence of PPH was 3.1% with misoprostol and 9.1% with oxytocin (P=0.002). No woman lost ≥ 1000 ml of blood. We observed that 9.7% and 45.6% of women experienced a haemoglobin decline of >10% after receiving misoprostol and oxytocin, respectively (P ≤ 0.001). Side effects were significantly greater in the misoprostol group than in the oxytocin group. Unlike other studies, this trial found sublingual misoprostol more effective than intramuscular oxytocin in reducing PPH, with only transient side effects being greater in the misoprostol group. The sublingual mode and/or powdered formulation may increase the effectiveness of misoprostol, and render it superior to injectable oxytocin for the prevention of PPH. Further research is needed to confirm these results. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

    Full Text Available Intravaginal practices-including behaviors such as intravaginal cleansing and insertion of products-have been linked to a number of adverse reproductive health outcomes, including increased risk for bacterial vaginosis, sexually transmitted infections, and HIV. Currently, little is known about the motivations for intravaginal practices among women in the United States. The objective of this study was to identify and describe motivations for intravaginal washing and intravaginal insertion of products among women of differing ages and racial/ethnic groups.Between 2008 and 2010, we enrolled a convenience sample of sexually active women aged 18-65 years living in Los Angeles recruited through community education and outreach activities in HIV/AIDS service organizations, women's health clinics, community-based organizations, and HIV testing sites. At the enrollment visit, women completed a self-administered, computer-assisted questionnaire covering demographics, sexual behaviors, intravaginal practices, and motivations for intravaginal practices over the past month and past year.We enrolled 141 women; 34% of participants were Caucasian, 40% African American, and 26% Latina. Peri-sexual intravaginal washing was common in all groups, whether to clean up after sex (70% or to prepare for sex (54%. African American women were more likely to report learning to wash intravaginally from their mothers compared to Latina or Caucasian women (70% vs. 49%, P = 0.04. Sixty-one percent of African American women reported using a douching device over the past year compared to 41% of Latina and 40% of Caucasian women (p = 0.02. Younger women were more likely to report that their male partners wanted them to wash intravaginally than older women (77% vs. 24%, P<0.01, and more likely to report the removal of odors as a motive than older women (65% vs. 40%, P = 0.04. The most commonly used intravaginal products included sexual lubricants, petroleum jelly, body lotions

    Community-based distribution of misoprostol for prevention of postpartum hemorrhage (PPH) in resource-poor settings has been shown to be safe and effective. However, global recommendations for prenatal distribution and monitoring within a community setting are not yet available. In order to successfully translate misoprostol and PPH research into policy and practice, several critical points must be considered. A focus on engaging the community, emphasizing the safe nature of community-based misoprostol distribution, supply chain management, effective distribution, coverage, and monitoring plans are essential elements to community-based misoprostol program introduction, expansion, or scale-up.

  4. Compartmental transport model of microbicide delivery by an intravaginal ring

    Topical antimicrobials, or microbicides, are being developed to prevent HIV transmission through local, mucosal delivery of antiviral compounds. While hydrogel vehicles deliver the majority of current microbicide products, intravaginal rings (IVRs) are an alternative microbicide modality in preclinical development. IVRs provide a long-term dosing alternative to hydrogel use, and might provide improved user adherence. IVR efficacy requires sustained delivery of antiviral compounds to the entire vaginal compartment. A two-dimensional, compartmental vaginal drug transport model was created to evaluate the delivery of drugs from an intravaginal ring. The model utilized MRI-derived ring geometry and location, experimentally defined ring fluxes and vaginal fluid velocities, and biophysically relevant transport theory. Model outputs indicated the presence of potentially inhibitory concentrations of antiviral compounds along the entire vaginal canal within 24 hours following IVR insertion. Distributions of inhibitory concentrations of antiviral compounds were substantially influenced by vaginal fluid flow and production, while showing little change due to changes in diffusion coefficients or ring fluxes. Additionally, model results were predictive of in vivo concentrations obtained in clinical trials. Overall, this analysis initiates a mechanistic computational framework, heretofore missing, to understand and evaluate the potential of IVRs for effective delivery of antiviral compounds.

    This study aims to evaluate the efficacy and side-effects of 200 μg sublingual misoprostol vs 5 IU i.m. oxytocin, administered immediately following cord clamping in normal non-augmented vaginal delivery, in prevention of postpartum haemorrhage (PPH). A total of 104 women were randomised into three groups: misoprostol group (28 patients); oxytocin group (37 patients) and control group (39 patients). Misoprostol and oxytocin significantly minimised the blood loss during the third stage of labour and reduced the need for additional treatments for PPH as compared with the control group. Oxytocin was more effective than misoprostol in minimising blood loss and the need for additional uterotonic treatments. However, a significant decrease in systolic and diastolic blood pressure, associated with tachycardia was observed in the oxytocin group. In conclusion, sublingual misoprostol appears to be less effective than i.m. oxytocin in the prevention of PPH; however, it has the potential advantages of being easily used, cost-effective and stable at room temperature. Therefore, sublingual misoprostol is still a feasible drug for routine management of third stage, especially in areas with limited medical facilities.

    Misoprostol (SC-29333), a synthetic prostaglandin E1 methyl ester analog, was given simultaneously with acetylsalicylic acid in a double-blind, placebo-controlled randomized prospective study of 32 healthy human male subjects. Fecal blood loss was measured for eight days using the 51 Cr-labeled red blood cell technique. Aspirin (650 mg qid) and misoprostol (25 micrograms qid) or placebo were given during days 3, 4, and 5. There was a significant (P less than 0.05) increase in median blood loss (modified Friedman test) from 0.81 to 6.05 ml/day in the aspirin with placebo group (N = 16). Median blood loss was increased (from 0.75 to 3.75 ml/day) in the aspirin with misoprostol group (N = 16), but this was significantly less (Mann-Whitney U test, P less than 0.01) than the placebo group. Mean serum salicylate concentrations in the placebo and misoprostol groups were similar (7.8 and 6.8 micrograms/ml, respectively). There were no significant changes in laboratory values in any of the subjects studied, nor were any major side-effects encountered. This study demonstrates that oral misoprostol reduces aspirin-induced gastrointestinal bleeding even when administered simultaneously and at a dose level below its threshold for significant acid inhibition. This indicates a potential role for misoprostol in the prevention of gastric mucosal damage in selected patients

    Full Text Available BACKGROUND The third stage of labour is indeed the unforgiving stage of the labour and in it lurks more unheralded treachery than in both the other stages of labour combined. Many lifesaving drugs have been discovered and used for the management of this stage of labour. According to the WHO multicentric randomised trial using oral misoprostol with oxytocic, they concluded that oral misoprostol was associated with significantly high incidence of side effects like shivering and rise in body temperature and hence oxytocin is preferred to 600 mg of oral misoprostol in management of 3rd stage of labour in hospital settings, but still misoprostol has been suggested for the management of third stage of labour in developing countries, because it has strong uterotonic effects, can be given orally, inexpensive and does not need refrigeration. The aim of the study is to compare oxytocin, misoprostol, methylergometrine for active management of the third stage of labour. MATERIALS AND METHODS A total of 300 women of 37 weeks to 42 weeks of gestation delivering vaginally in Konaseema Institute of Medical Sciences, Amalapuram, Andhra Pradesh. 300 women allocated into 3 groups of 100 each to receive 10 IU I.M. oxytocin, 600 mcg sublingual misoprostol or 200 mcg I.M. methylergometrine, respectively. Primary outcome measure was blood loss in the third stage of labor; secondary measures were duration of the third stage, side effects and complications. RESULTS Subjects who received 600 mcg of misoprostol had the least blood loss (113 mL, followed by oxytocin and methylergometrine. The shortest mean duration of the third stage was with misoprostol (4.34 mins.. Shivering and pyrexia were observed in misoprostol group and raised blood pressure in methylergometrine group. CONCLUSION Misoprostol is as effective as oxytocin and both are more effective than methylergometrine in active management of the third stage of labour. Misoprostol therefore can be used in places

    Prostaglandin E 2 (PGE 2 ) is an anti-inflammatory compound that inhibits 5-lipoxygenase activity. Diminished PGE 2 regulation in aspirin-exacerbated respiratory disease (AERD) leads to respiratory reactions on cyclooxygenase 1 inhibition. In vitro studies have found that exogenous PGE 2 stabilizes inflammatory mediator release. To examine whether misoprostol (oral prostaglandin E 1 analogue) use during aspirin challenge and desensitization might decrease the severity of aspirin-induced symptoms and make desensitization safer for patients with AERD. Forty-five patients undergoing aspirin challenge and/or desensitization were randomized to misoprostol (n = 30) or placebo (n = 15) and compared with a group of historical controls (n = 31). Misoprostol (200 μg) was administered at 30 minutes, 90 minutes, and 4 hours after the first dose of nasal ketorolac. Measured end points included change in forced expiratory volume in 1 second (FEV 1 ), peak nasal inspiratory flow rate (PNIF), number of treatments received for induced reactions, and adverse gastrointestinal effects. A difference in FEV 1 and PNIF reduction was detected between misoprostol and placebo (P = .03) and misoprostol and historical controls (P = .01), respectively, during nasal ketorolac challenge. No difference was detected among aspirin reactors. Among all reactors, no difference in magnitude was found for FEV 1 (P = .13) or PNIF (P = .07) reduction across all 3 groups. Total treatment requirement was similar (P = .14). Patients receiving misoprostol were more likely to report adverse gastrointestinal effects (P = .02). The addition of misoprostol to current aspirin challenge and/or desensitization protocols reveals no protective effect in reducing the intensity of nonsteroidal anti-inflammatory drug-induced symptoms and is not recommended based on the findings in this study.

    Full Text Available Objectives: Non-invasive methods of inducing a miscarriage are now considered an effective alternative to surgical evacuation (dilatation and curettage. This study aimed to evaluate the effectiveness of misoprostol in the termination of first-trimester miscarriages. Methods: This prospective study was conducted between October 2009 and September 2010 and assessed all patients admitted to the Royal Hospital in Muscat, Oman, for the termination of first-trimester miscarriages during the study period. All patients received misoprostol and the rates of successful termination were measured. Patient satisfaction was assessed using a short questionnaire. Results: A total of 290 women were included in the study. Termination with misoprostol was successful in 61.38% of the subjects. Of the remaining subjects requiring additional surgical evacuation (n = 112, 58.93% required evacuation due to failed termination with misoprostol and 65.18% underwent early evacuation (≤24 hours since their last misoprostol dose. The majority of patients experienced no side-effects due to misoprostol (89.66%. Pain was controlled with simple analgesics in 70.00% of the subjects. A high satisfaction rate (94.83% with the misoprostol treatment was reported. Conclusion: Misoprostol was a well-tolerated drug which reduced the rate of surgical evacuation among the study subjects. This medication can therefore be used safely in the management of incomplete miscarriages.

    Full Text Available Background: Incomplete abortions can be managed expectantly, surgically and medically (using misoprostol. Expectant management is safe in places where women have access to information, appropriate care and follow-up; however, in isolated and poor areas women who come for help need an intervention. Objective: To compare the efficiency of manual vacuum aspiration (MVA and misoprostol in the treatment of incomplete abortion. Patients and method: This was a prospective study over five months from March to August 2015. All patients admitted with a diagnosis of incomplete abortion were recruited into the study. Results: 308 patients with incomplete abortion were randomized into two treatment groups - MVA (done under local anaesthesia and misoprostol (400 micrograms by the vaginal route. MVA was successfully performed for all patients. Two patients presented with anaemia. In the misoprostol group, 23 patients had vaginal bleeding, and 10 persistence of incomplete abortion. Conclusion: MVA is more effective than misoprostol with less complications in the treatment of incomplete abortion when it is done by a trained person.

    Induction of COX-2 activity in cerebral ischemia results in increased neuronal injury and infarct size. Recent studies investigating neurotoxic mechanisms of COX-2 demonstrate both toxic and paradoxically protective effects of downstream prostaglandin receptor signaling pathways. We tested whether misoprostol, a PGE(2) receptor agonist that is utilized clinically as an anti-ulcer agent and signals through the protective PGE(2) EP2, EP3, and EP4 receptors, would reduce brain injury in the murine middle cerebral artery occlusion-reperfusion (MCAO-RP) model. Administration of misoprostol, at the time of MCAO or 2h after MCAO, resulted in significant rescue of infarct volume at 24 and 72h. Immunocytochemistry demonstrated dynamic regulation of the EP2 and EP4 receptors during reperfusion in neurons and endothelial cells of cerebral cortex and striatum, with limited expression of EP3 receptor. EP3-/- mice had no significant changes in infarct volume compared to control littermates. Moreover, administration of misoprostol to EP3+/+ and EP3-/- mice showed similar levels of infarct rescue, indicating that misoprostol protection was not mediated through the EP3 receptor. Taken together, these findings suggest a novel function for misoprostol as a protective agent in cerebral ischemia acting via the PGE(2) EP2 and/or EP4 receptors.

    To report on a rigorous distribution and monitoring plan to track misoprostol for community-based distribution to reduce postpartum haemorrhage (PPH) in rural Ghana. Operations research. Rural Ghana. Women in third trimester of pregnancy presenting to primary health centres (PHCs) for antenatal care (ANC). Ghana Health Service (GHS), Millennium Village Projects, and the University of Illinois at Chicago conducted an operations research study designed to assess the safety, feasibility, and acceptability of community-based distribution of misoprostol to prevent PPH at home deliveries in rural Ghana. One thousand doses (3000 tablets, 200 μg each) were obtained from the Family Health Division of GHS. Three 200-μg tablets of misoprostol (600 μg) in foil packets were packaged together in secured transparent plastic packets labelled with pictorial messages and distributed to midwives at seven PHCs for distribution to pregnant women. Correct use of misoprostol in home deliveries and retrieval of unused misoprostol doses, PPH rates and maternal mortality. Of the 999 doses distributed to midwives, 982 (98.3%) were successfully tracked, with a 1.7% lost to follow-up rate. Midwives distributed 654 doses to women at third-trimester ANC visits. Of women who had misoprostol to use at home, 81% had an institutional delivery and were able to return the misoprostol safely to the midwife. Of the women that used misoprostol, 99% used the misoprostol correctly. This study clearly demonstrates that misoprostol distributed antenatally to pregnant women can be used accurately and reliably by rural Ghanaian women, and should be considered for policy implementation across Ghana and other countries with high home birth rates and maternal mortality ratios. © 2013 Royal College of Obstetricians and Gynaecologists.

    The objective of this study is to compare the uterine activity response between women administered dinoprostone (prostaglandin E2) and misoprostol (prostaglandin E1) for induction of labour (IOL) by analysing not only the traditional obstetric data but also the parameters extracted from uterine electrohysterogram (EHG). Two cohorts were defined: misoprostol (25-µg vaginal tablets; 251 women) and dinoprostone cohort (10 mg vaginal inserts; 249 women). All the mothers were induced by a medical indication of a Bishop Score PMU) 60' after drug administration, while spectral parameters significantly increased after 150'. This response was not observed in failed inductions. In the successful dinoprostone group, the duration and number of contractions increased significantly after 120', PMU did so after 180', and no significant differences were found for spectral parameters, possibly due to the slower pharmacokinetics of this drug. Successful inductions of labour by misoprostol are associated with earlier effective contractions than in labours induced by dinoprostone.

    Intravaginal ejaculation latency time (IELT), defined as the time between the start of vaginal intromission and the start of intravaginal ejaculation, is increasingly used in clinical trials to assess the amount of selective serotonin reuptake inhibitor-induced ejaculation delay in men with premature ejaculation. Prospectively, stopwatch assessment of IELTs has superior accuracy compared with retrospective questionnaire and spontaneous reported latency. However, the IELT distribution in the general male population has not been previously assessed. To determine the stopwatch assessed-IELT distribution in large random male cohorts of different countries. A total of 500 couples were recruited from five countries: the Netherlands, United Kingdom, Spain, Turkey, and the United States. Enrolled men were aged 18 years or older, had a stable heterosexual relationship for at least 6 months, with regular sexual intercourse. The surveyed population were not included or excluded by their ejaculatory status and comorbidities. This survey was performed on a "normal" general population. Sexual events and stopwatch-timed IELTs during a 4-week period were recorded, as well as circumcision status and condom use. The IELT, circumcision status, and condom use. The distribution of the IELT in all the five countries was positively skewed, with a median IELT of 5.4 minutes (range, 0.55-44.1 minutes). The median IELT decreased significantly with age, from 6.5 minutes in the 18-30 years group, to 4.3 minutes in the group older than 51 years (PIELT varied between countries, with the median value for Turkey being the lowest, i.e., 3.7 minutes (0.9-30.4 minutes), which was significantly different from each of the other countries. Comparison of circumcised (N=98) and not-circumcised (N=261) men in countries excluding Turkey resulted in median IELT values of 6.7 minutes (0.7-44.1 minutes) in circumcised compared with 6.0 minutes (0.5-37.4 minutes) in not-circumcised men (not significant).

    Full Text Available OBJECTIVE: To analyze the misoprostol use in pregnancies with intrauterine fetal death (IUFD, considering mode of delivery and induction-delivery interval. METHODS: Descriptive study including 171 pregnant women with IUFD, in the second or third trimester, submitted to labor induction with vaginal misoprostol and/or induction/augmentation with intravenous oxytocin, from 2005 to 2008, at a teaching-hospital of the Brazilian Unified Health System (Sistema Único de Saúde -SUS. RESULTS: Misoprostol alone (treatment A, misoprostol plus oxytocin (treatment B, and oxytocin alone (treatment C were administered in 9.3%, 19.9%, and 70.8% of the cases, respectively. One-third of pregnancies were less than 28 weeks, and 2.9% required a caesarean section. The percentage of vaginal delivery in treatments A and B combined (98.0% was similar to treatment C (96.7%. The mean induction-delivery interval was 15.4 hours. Comparing multiple groups, the mean induction-delivery interval was significantly shorter in treatment A (20.1 hours than in treatment B (33.3 hours, and was longer than in treatment C (9.7 hours. The majority (71% of cases required a single administration of misoprostol, and the total dosage was lower in treatment A (mean: 98.4 µg compared with treatment B (mean: 157.0 µg. CONCLUSION: Misoprostol effectively contributed to delivery of IUFD by vaginal route assisted under routine conditions of a public health service in Brazil, demonstrating its importance in cases resistant to usual induction methods, and its availability in Brazilian public health services is recommended.

    We aimed to document the experience of buying abortion pills from online vendors that do not require a prescription and to evaluate the active ingredient content of the pills received. We searched the internet to identify a convenience sample of websites that sold mifepristone and misoprostol to purchasers in the United States and attempted to order these products. We documented price, shipping time and other aspects of ordering. We sent the samples received to a testing laboratory that measured the amount of active ingredient in individual tablets. We identified 18 websites and ordered 22 products: 20 mifepristone-misoprostol combination products and 2 that contained only misoprostol. We received 18 combination products and the 2 misoprostol products from 16 different sites. No site required a prescription or any relevant medical information. The time between order and receipt of the 20 products ranged from 3 to 21 business days (median 9.5 days). The price for the 18 combination products ranged from $110 to $360, including shipping and fees; the products without mifepristone cost less. Chemical assays found that the 18 tablets labeled 200 mg mifepristone contained between 184.3 mg and 204.1 mg mifepristone, while the 20 tablets labeled 200 mcg misoprostol contained between 34.1 mcg and 201.4 mcg of the active ingredient. Obtaining abortion medications from online pharmaceutical websites is feasible in the United States. The mifepristone tablets received contained within 8% of the labeled amount of active agent. The misoprostol tablets all contained that compound but usually less than labeled. Given our findings, we expect that some people for whom clinic-based abortion is not easily available or acceptable may consider self-sourcing pills from the internet to be a rational option.

    Full Text Available Background. Misoprostol is commonly used for induction of labour in term pregnancy. There are different routes and dosing schedules for administering the drug.Objectives. To describe the prescribing pattern (dose, route, duration, beliefs and factors affecting use of misoprostol for inducing term pregnancy among practising obstetricians in Zimbabwe.Methods. A cross-sectional descriptive survey was undertaken among practising obstetricians in Zimbabwe. A questionnaire was sent as an email, WhatsApp or short message service (SMS, or text web link to all practising obstetricians in Zimbabwe using the SurveyMonkey online tool. All consenting practitioners were requested to respond online. The responses were analysed using the SurveyMonkey software.Results. There were 52 responses from the 63 questionnaires, a response rate of 82.5%. Seventy-six percent preferred oral misoprostol for induction of labour. The most common indication for induction was prolonged pregnancy accounting for 58% of respondents. The largest group of the practitioners who responded (36% learnt their misoprostol dosing regimen from WHO/FIGO/NICE guidelines. A composite of highly variable dose regimens referred to as ‘other regimens’ was the dosing regimen preferred by 34% of respondents. Fiftyeight percent of practitioners used two cycles of misoprostol dosing before concluding that induction had failed and 52% would resort to caesarean section immediately if induction failed.Conclusion. The results show marked heterogeneity in the dosing schedules employed by obstetricians for induction of labour with the majority not following standard misoprostol guidelines for labour induction.

  1. Potential Cost-Effectiveness of Prenatal Distribution of Misoprostol for Prevention of Postpartum Hemorrhage in Uganda.

    Full Text Available In settings where home birth rates are high, prenatal distribution of misoprostol has been advocated as a strategy to increase access to uterotonics during the third stage of labor to prevent postpartum hemorrhage (PPH. Our objective was to project the potential cost-effectiveness of this strategy in Uganda from both governmental (the relevant payer and modified societal perspectives.To compare prenatal misoprostol distribution to status quo (no misoprostol distribution, we developed a decision analytic model that tracked the delivery pathways of a cohort of pregnant women from the prenatal period, labor to delivery without complications or delivery with PPH, and successful treatment or death. Delivery pathway parameters were derived from the Uganda Demographic and Health Survey. Incidence of PPH, treatment efficacy, adverse event and case fatality rates, access to misoprostol, and health resource use and cost data were obtained from published literature and supplemented with expert opinion where necessary. We computed the expected incidence of PPH, mortality, disability adjusted life years (DALYs, costs and incremental cost effectiveness ratios (ICERs. We conducted univariate and probabilistic sensitivity analyses to examine robustness of our results. In the base-case analysis, misoprostol distribution lowered the expected incidence of PPH by 1.2% (95% credibility interval (CrI: 0.55%, 1.95%, mortality by 0.08% (95% CrI: 0.04%, 0.13% and DALYs by 0.02 (95% CrI: 0.01, 0.03.” and “ICERs were US$181 (95% CrI: 81, 443 per DALY averted from a governmental perspective, and US$64 (95% CrI: -84, 260 per DALY averted from a modified societal perspective [corrected].Prenatal distribution of misoprostol is potentially cost-effective in Uganda and should be considered for national-level scale up for prevention of PPH.

    Background A postpartum hemorrhage prevention program to increase uterotonic coverage for home and facility births was introduced in two districts of Liberia. Advance distribution of misoprostol was offered during antenatal care (ANC) and home visits. Feasibility, acceptability, effectiveness of distribution mechanisms and uterotonic coverage were evaluated. Methods Eight facilities were strengthened to provide PPH prevention with oxytocin, PPH management and advance distribution of misoprostol during ANC. Trained traditional midwives (TTMs) as volunteer community health workers (CHWs) provided education to pregnant women, and district reproductive health supervisors (DRHSs) distributed misoprostol during home visits. Data were collected through facility and DRHS registers. Postpartum interviews were conducted with a sample of 550 women who received advance distribution of misoprostol on place of delivery, knowledge, misoprostol use, and satisfaction. Results There were 1826 estimated deliveries during the seven-month implementation period. A total of 980 women (53.7%) were enrolled and provided misoprostol, primarily through ANC (78.2%). Uterotonic coverage rate of all deliveries was 53.5%, based on 97.7% oxytocin use at recorded facility vaginal births and 24.9% misoprostol use at home births. Among 550 women interviewed postpartum, 87.7% of those who received misoprostol and had a home birth took the drug. Sixty-three percent (63.0%) took it at the correct time, and 54.0% experienced at least one minor side effect. No serious adverse events reported among enrolled women. Facility-based deliveries appeared to increase during the program. Conclusions The program was moderately effective at achieving high uterotonic coverage of all births. Coverage of home births was low despite the use of two channels of advance distribution of misoprostol. Although ANC reached a greater proportion of women in late pregnancy than home visits, 46.3% of expected deliveries did not

    Full Text Available Identifying modifiable factors that increase women's vulnerability to HIV is a critical step in developing effective female-initiated prevention interventions. The primary objective of this study was to pool individual participant data from prospective longitudinal studies to investigate the association between intravaginal practices and acquisition of HIV infection among women in sub-Saharan Africa. Secondary objectives were to investigate associations between intravaginal practices and disrupted vaginal flora; and between disrupted vaginal flora and HIV acquisition.We conducted a meta-analysis of individual participant data from 13 prospective cohort studies involving 14,874 women, of whom 791 acquired HIV infection during 21,218 woman years of follow-up. Data were pooled using random-effects meta-analysis. The level of between-study heterogeneity was low in all analyses (I(2 values 0.0%-16.1%.

    To compare labor induction intervals between oral misoprostol and intravenous oxytocin in women who present at term with premature rupture of membranes. One hundred eight women were randomly assigned to misoprostol 50 microg orally every 4 hours as needed or intravenous oxytocin. The primary outcome measure was time from induction to vaginal delivery. Sample size was calculated using a two-tailed alpha of 0.05 and power of 80%. Baseline demographic data, including maternal age, gestation, parity, Bishop score, birth weight, and group B streptococcal status, were similar. The mean time +/-standard deviation to vaginal birth with oral misoprostol was 720+/-382 minutes compared with 501+/-389 minutes with oxytocin (P = .007). The durations of the first, second, and third stages of labor were similar. There were no differences in maternal secondary outcomes, including cesarean birth (eight and seven, respectively), infection, maternal satisfaction with labor, epidural use, perineal trauma, manual placental removal, or gastrointestinal side effects. Neonatal outcomes including cord pH, Apgar scores, infection, and admission to neonatal intensive care unit were not different. Although labor induction with oral misoprostol was effective, oxytocin resulted in a shorter induction-to-delivery interval. Active labor intervals and other maternal and neonatal outcomes were similar.

    To identify clinical indicators for success of misoprostol treatment after early pregnancy failure. A total of 473 women with early pregnancy failure received 800 microg of vaginal misoprostol on treatment day 1. At the follow-up visit on day 3, a second dose was given if expulsion was incomplete. On day 8, vacuum aspiration was offered if expulsion had not occurred. Ultrasonography was used as gold standard for success. A Classification and Regression Tree analysis was undertaken to derive two decision trees for the success of misoprostol treatment on study days 3 and 8. Heavy bleeding after the first dose and an open cervical os were identified as clinical indicators of treatment success on day 3. Treatment success occurred in 84% of women with either or both indicators. Reporting passage of tissue after a second misoprostol dose and old blood in the vagina were potential indicators of treatment success or failure on day 8. A woman with either of these indicators has a 65% chance of treatment success after the second dose. Conversely, a woman with neither indicator on day 8 has a 94% chance of treatment failure. Standard clinical findings may be useful as indicators for success or failure of medical management of early pregnancy failure in settings with limited or no access to ultrasonography. More research to identify even better indicators is warranted.

    Full Text Available Postpartum hemorrhage (PPH is the commonest cause of maternal death worldwide. Studies suggest that the use of misoprostol may be beneficial in clinical settings where oxytocin is unavailable. The aim of this study was to compare the safety and efficacy of oxytocin and misoprostol when used in the prevention of PPH. In a double-blind randomized controlled trial, 400 pregnant women who had a vaginal delivery were assigned into two groups: to receive either 20 IU of oxytocin in 1000 mL Ringer’s solution and two placebo tablets or 400 mcg oral misoprostol (as two tablets and 2 mL normal saline in 1000 mL Ringer’s solution. The quantity of blood loss was higher in the oxytocin group in comparison to the misoprostol group. There was no significant difference in the decrease in hematocrit and hemoglobin between the two groups. Although there was no significant difference in the need for transfusions between the two groups, the patients in the oxytocin group had greater need for additional oxytocin. Results from this study indicate that it may be considered as an alternative for oxytocin in low resource clinical settings. This study is registered with ClinicalTrials.gov NCT01863706.

    While inferior to oxytocin injection in both efficacy and safety, orally administered misoprostol has been included in the World Health Organization Model List of Essential Medicines for use in the prevention of postpartum haemorrhage (PPH) in low-resource settings. This study evaluates the costs and health outcomes of use of oral misoprostol to prevent PPH in settings where injectable uterotonics are not available. A cost-consequences analysis was conducted from the international health system perspective, using data from a recent Cochrane systematic review and WHO's Mother-Baby Package Costing Spreadsheet in a hypothetical cohort of 1000 births in a mixed hospital (40% births)/community setting (60% births). Costs were estimated based on 2012 US dollars. Using oxytocin in the hospital setting and misoprostol in the community setting in a cohort of 1000 births, instead of oxytocin (hospital setting) and no treatment (community setting), 22 cases of PPH could be prevented. Six fewer women would require additional uterotonics and four fewer women a blood transfusion. An additional 130 women would experience shivering and an extra 42 women fever. Oxytocin/misoprostol was found to be cost saving (US$320) compared to oxytocin/no treatment. If misoprostol is used in both the hospital and community setting compared with no treatment (i.e. oxytocin not available in the hospital setting), 37 cases of PPH could be prevented; ten fewer women would require additional uterotonics; and six fewer women a blood transfusion. An additional 217 women would experience shivering and 70 fever. The cost savings would be US$533. Sensitivity analyses indicate that the results are sensitive to the incidence of PPH-related outcomes, drug costs and the proportion of hospital births. Our findings confirm that, even though misoprostol is not the optimum choice in the prevention of PPH, misoprostol could be an effective and cost-saving choice where oxytocin is not or cannot be used due to a

    Full Text Available Background: Sustained release diclofenac (diclofenac SR is the commonly used non-steroidal anti-inflammatory drug for chronic inflammatory conditions such as rheumatoid arthritis. Misoprostol, prostaglandin analogue, is the agent that enhances gastrointestinal mucosal defense. Concomitant administration of misoprostol with diclofenac SR can prevent the gastrointestinal side effects of diclofenac SR. Objective: The purpose of the study was to explore the effect of misoprostol on the pharmacokinetics of diclofenac SR in healthy volunteers. Methods: Crossover study was evaluated in 14 male volunteers. Single oral dose of 100 mg diclofenac SR was concomitantly administered with 200 μg misoprostol with one-week wash out period. Plasma concentrations at 0, 0.5, 1, 1.5, 2, 3, 6 and 10 hrs were determined by high performance liquid chromatography (HPLC. Pharmacokinetic parameters such as area under concentration-time curve (AUC0-α, peak plasma concentration (Cmax, time to achieve peak plasma concentration (Tmax, absorption half-life (T½(ab, elimination half-life (T1/2(el, absorption rate constant (Kab, and elimination rate constant (Kel were determined. Results: With misoprostol, the mean AUC0-α of diclofenac SR was significantly reduced from 12.11±5.25μg/ mL×hr to 4.17±2.72μg/mL×hr (p0.05. The mean T½(ab was decreased from 0.56±0.23hr to 0.54±0.19hr (p>0.05. The mean Kab were almost the same 1.43±0.54hr-1 and 1.43±0.48hr-1. The mean T1/2(el was decreased from 3.68±1.64hr to 3.03±1.08hr (p>0.05. The mean Kel was increased from 0.21±0.09hr-1 to 0.25±0.09hr-1 (p>0.05. Conclusion: There was a significant reduction in the extent of absorption of diclofenac SR when concomitantly administered with misoprostol. Therefore, the dose of diclofenac SR may need to be increased to avoid therapeutic failure of diclofenac SR or concurrent use with misoprostol may need to be changed to other gastroprotective agents.

    Postpartum heammorrhage (PPH), defined as blood loss greater than or equal to 500 ml within 24 hours after birth, is the leading cause of maternal deaths globally and in India. Misoprostol is an important option for PPH management in setting where oxytocin (the gold standard for PPH prevention and treatment) in not available or not feasible to use. For the substantial number of deliveries which take place at home or at lower level heatlh facilities in India, misoprostol pills can be adminstered to prevent PPH. The standard approach using misoprostol is to administer it prophylactically as primary prevention (600 mcg). An alternative strategy could be to administer misoprostol only to those who are at high risk of having PPH i.e. as secondary prevention. This study reports on the relative cost per person of a strategy involving primary versus secondary prevention of PPH using misoprostol. It is based on a randomized cluster trial that was conducted in Bijapur district in Karnataka, India between December 2011 and March 2014 among pregnant women to compare two community-level strategies for the prevention of PPH: primary and secondary. The analysis was conducted from the government perspective using an ingredient approach. The cluster trial showed that there were no significant differences in clinical outcomes between the two study arms. However, the results of the cost analysis show that there is a difference of INR 6 (US$ 0.1) per birth for implementing the strategies primary versus secondary prevention. In India where 14.9 million births take place at sub-centres and at home, this additional cost of INR 6 per birth translates to an additional cost of INR 94 (US$ 1.6) million to the government to implement the primary prevention compared to the secondary prevention strategy. As clinical outcomes did not differ significantly between the two arms in the trial, taking into account the difference in costs and potential issues with sustainability, secondary prevention

    Full Text Available Intravaginal testicular torsion is a very rare pathology in the neonatal period. However, it is the most common type of torsion in puberty. In this article, we present a male patient with testicular hyperemia and a mass in the testis. Ultrasonography revealed intravaginal testicular torsion and absence of testicular blood flow. This paper aims to draw attention to the importance of neonatal examination for the presence of testicular torsion which is a rare pathology in newborns with scrotal colour change or presence of an abnormal mass.

  18. An Unreported Uterine Rupture in an Unscarred Uterus After Induced Labor With 25 μg Misoprostol Vaginally

    Full Text Available Uterine rupture without a former history of cesarean delivery or uterine scarring is an exceedingly rare complication in pregnancy and labor. Misoprostol is widely used to induce labor but there is a lack of knowledge about serious adverse effects. It is especially challenging to collect reports on side effects because misoprostol is not a registered drug. We report a case of a woman induced by one dose 25 μg misoprostol vaginally. Her pregnancy was uncomplicated and she had an unscarred uterus. Her labor progressed rapidly and she experienced hyperstimulation, meconium stained amniotic fluid, uterine rupture, and excessive blood loss of approximately 14 l. The child survived but is diagnosed with cerebral palsy. The case was never reported as an adverse event. This case questions the safety of misoprostol even in low dosage. It also underlines the need to report side effects to national reporting systems.

    Hemorrhage continues to be a leading cause of maternal death in developing countries. The 2012 World Health Organization guidelines for the prevention and management of postpartum hemorrhage (PPH) recommend oral administration of misoprostol by community health workers (CHWs). However, there are several outstanding questions about distribution of misoprostol for PPH prevention at home births. We conducted an integrative review of published research studies and evaluation reports from programs that distributed misoprostol at the community level for prevention of PPH at home births. We reviewed methods and cadres involved in education of end-users, drug administration, distribution, and coverage, correct and incorrect usage, and serious adverse events. Eighteen programs were identified; only seven reported all data of interest. Programs utilized a range of strategies and timings for distributing misoprostol. Distribution rates were higher when misoprostol was distributed at a home visit during late pregnancy (54.5-96.9%) or at birth (22.5-83.6%), compared to antenatal care (ANC) distribution at any ANC visit (22.5-49.1%) or late ANC visit (21.0-26.7%). Coverage rates were highest when CHWs and traditional birth attendants distributed misoprostol and lower when health workers/ANC providers distributed the medication. The highest distribution and coverage rates were achieved by programs that allowed self-administration. Seven women took misoprostol prior to delivery out of more than 12,000 women who were followed-up. Facility birth rates increased in the three programs for which this information was available. Fifty-one (51) maternal deaths were reported among 86,732 women taking misoprostol: 24 were attributed to perceived PPH; none were directly attributed to use of misoprostol. Even if all deaths were attributable to PPH, the equivalent ratio (59 maternal deaths/100,000 live births) is substantially lower than the reported maternal mortality ratio in any of these

    Misoprostol use for postpartum haemorrhage (PPH) has been promoted by Civil Society Organizations (CSOs) since the early 2000s. Yet, CSOs' role in improving access to misoprostol and shaping health policy at global and national levels is not well understood. We document the introduction of misoprostol in Uganda in 2008 from its registration, addition to treatment guidelines and national Essential Medicines List (EML), to its distribution and use. We then analyse the contribution of CSOs to this health policy change and service provision. Policy documents, procurement data and 82 key informant interviews with government officials, healthcare providers, and CSOs in four Ugandan districts of Kampala, Mbarara, Apac, Bundibugyo were collected between 2010 and 2013. Five key CSOs promoted and accelerated the rollout of misoprostol in Uganda. They supported the registration of misoprostol with the National Drug Authority, the development of clinical guidelines, and the piloting and training of health care providers. CSOs and National Medical Stores were procuring and distributing misoprostol country-wide to health centres two years before it was added to the clinical guidelines and EML of Uganda and in the absence of good evidence. The evidence suggests an increasing trend of misoprostol procurement and availability over the medicine of choice, oxytocin. This shift in national priorities has serious ramifications for maternal health care that need urgent evaluation. The absence of clinical guidelines in health centres and the lack of training preclude rational use of misoprostol. CSOs shifted their focus from the public to the private sector, where some of them continue to promote its use for off-label indications including induction of labour and abortion. There is an urgent need to build capacity to improve the robustness of the national and local institutions in assessing the safety and effectiveness of all medicines and their indications in Uganda.

    This is one of a series of reviews of cervical ripening and labour induction using standardised methodology. Misoprostol administered by the oral and sublingual routes have the advantage of rapid onset of action, while the sublingual and vaginal routes have the advantage of prolonged activity and greatest bioavailability. To determine the effectiveness and safety of misoprostol administered buccally or sublingually for third trimester cervical ripening and induction of labour. We searched the Cochrane Pregnancy and Childbirth Group trials register (8 December 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2003), and bibliographies of relevant papers. Randomised controlled trials comparing buccal or sublingual misoprostol used for third trimester cervical ripening or labour induction with placebo/no treatment or other methods listed above it on a predefined list of labour induction methods. A generic strategy was developed to deal with the large volume and complexity of trial data relating to labour induction. Data were extracted onto standardized forms, checked for accuracy, and analysed using RevMan software. Three studies (502 participants) compared buccal/sublingual misoprostol respectively with a vaginal regimen (200 microg versus 50 microg) and with oral administration (50 versus 50 microg and 50 versus 100microg).The buccal route was associated with a trend to fewer caesarean sections than with the vaginal route (18/73 versus 28/79; relative risk (RR) 0.70; 95% confidence interval (CI) 0.42 to 1.15). There were no significant differences in any other outcomes. When the same dosage was used sublingually versus orally, the sublingual route was associated with less failures to achieve vaginal delivery within 24 hours (12/50 versus 19/50; RR 0.63, 95% CI 0.34 to 1.16), reduced oxytocin augmentation (17/50 versus 23/50; RR 0.74, 95% CI 0.45 to 1.21) and reduced caesarean section (8/50 versus 15/50; RR 0.53, 95% CI 0.25 to

    Accelerated drug release testing is a valuable quality control tool for long-acting non-oral extended release formulations. Currently, several intravaginal ring candidates designed for the long-term delivery of steroids or anti-infective drugs are being in the developing pipeline. The present article addresses the demand for accelerated drug release methods for these formulations. We describe the development and evaluation of accelerated release methods for a steroid releasing matrix-type intravaginal ring. The drug release properties of the formulation were evaluated under real-time and accelerated test conditions. Under real-time test conditions drug release from the intravaginal ring was strongly affected by the steroid solubility in the release medium. Under sufficient sink conditions that were provided in release media containing surfactants drug release was Fickian diffusion driven. Both temperature and hydro-organic dissolution media were successfully employed to accelerate drug release from the formulation. Drug release could be further increased by combining the temperature effect with the application of a hydro-organic release medium. The formulation continued to exhibit a diffusion controlled release kinetic under the investigated accelerated conditions. Moreover, the accelerated methods were able to differentiate between different prototypes of the intravaginal ring that exhibited different release profiles under real-time test conditions. Overall, the results of the present study indicate that both temperature and hydro-organic release media are valid parameters for accelerating drug release from the intravaginal ring. Variation of either a single or both parameters yielded release profiles that correlated well with real-time release. Copyright © 2016 Elsevier B.V. All rights reserved.

    Complaints of premature ejaculation (PE) and its repercussions are culture-dependent. To report the measured intravaginal ejaculatory latency time (IELT) and the impact of PE in Kermanshah, Iran. From November 1996 through October 2008, 3,458 patients presented to us with self-diagnosed PE. In the first visit, after obtaining a psychosocial and sexual history, PE-specific bother was self-rated by the patients and the patients were advised to measure their IELTs over the next 2-3 weeks. In the second visit, the measured IELTs were reported by the patients. Patients' measured IELT and bother score. Age range was 17-80 years (mean 34.1, standard deviation [SD] 9.1, median 32). Sixty-five percent were married. Primary and secondary PE was reported by 2,105 (60.8%) and 1,353 (39.1%) patients, respectively. Occasional PE was reported by 36 (0.01%). Of those with multiple partners, 6% had partner-specific PE. IELT distribution was positively skewed. Anteportal ejaculation was reported by 97 (2.8%). In 3,458 self-reported PE patients, IELT was 1-15 seconds in 542 (15.7%), 16-30 seconds in 442 (12.8%), 31-60 seconds in 978 (28.3%), > 1 2 5 minutes in 136 (3.9%). IELTs of IELT and bother (r = -0.607) was highly negative, with shorter IELTs being correlated with more bother. Six hundred forty-three patients (18.6%) always consumed opium to lengthen their IELTs. All 21 patients who started to use Tramadol as a PE treatment became addicted to it. Of 168 divorced couples due to PE, 23 divorced because the sexually dissatisfied wives became involved in extramarital affairs. Applying the Diagnostic and Statistical Manual of Mental Disorders criteria for PE and a cutoff IELT point of IELTs of longer than 2 minutes, the patients with occasional PE, and the patients who reported no personal bother, of 3,458 self-reported PE patients, 2,571 (74.3%) had PE. Including the 97 patients with anteportal ejaculation, arithmetic mean IELT in 2,571 patients was 45.87 seconds, SD 36.1, median

  5. The biomedicalisation of illegal abortion: the double life of misoprostol in Brazil

    Silvia De Zordo

    Full Text Available Abstract This paper examines the double life of misoprostol in Brazil, where it is illegally used by women as an abortifacient and legally used in obstetric hospital wards. Based on my doctoral and post-doctoral anthropological research on contraception and abortion in Salvador, Bahia, this paper initially traces the “conversion” of misoprostol from a drug to treat ulcers to a self-administered abortifacient in Latin America, and its later conversion to aneclectic global obstetric tool. It then shows how, while reducing maternal mortality, its use as an illegal abortifacient has reinforced the double reproductive citizenship regime existing in countries with restrictive abortion laws and poor post-abortion care services, where poor women using it illegally are stigmatised, discriminated against and exposed to potentially severe health risks.

    To compare the effectiveness of per rectal misoprostol over oxytocin in primary postpartum haemorrhage (PPH). Randomised controlled trial study. Gynaecology and Obstetrics Department, Unit IV, Bolan Medical Complex Hospital, Quetta, from September 2013 to February 2014. Emergency obstetric patients receiving per rectal misoprostol (800 µgm) were named as group 'A' and those receiving 10 units oxytocin intramuscularly were labelled as group 'B'. The patients were followed within 24 hours of spontaneous vaginal deliveries. Pads soaked were used to assess the amount of blood loss. A total of 1,678 patients were included in the study. The mean age of patients in group-A was 29.11 years while the mean age of patients in group-B was 29.16 years. One hundred and twenty-three (14.66%) patients in group-A and 120 (14.31%) patients in group-B had PPH. Among the total 1,678 patients, 243 (14.49%) had postpartum haemorrhage among whom 24 (9.88%) had major haemorrhage with a blood loss ≥1000 mL. Among the sub-group (839 patients) administered misoprostol had 123 (14.66%) patients with blood loss greater than 500 mL and the rest 716 patients (85.34%) had blood loss less than 500 mL. The sub-group administered oxytocin have 120 (14.31%) out of 839 patients with postpartum haemorrhage while 719 (85.69%) had blood loss less than 500 mL. Active management of 3rd stage of labour with per rectal misoprostol administration was as effective as intramuscular oxytocin. Both were equally effective to reduce PPH and the subsequent need for surgical interventions.

    Full Text Available BACKGROUND Lower segment caesarean section is a common surgical procedure. Postpartum haemorrhage incidence after LSCS is 4%. Misoprostol is a prostaglandin E1 analogue with good uterotonic properties, easy availability, low cost, thermostability, long shelf life, easy administration and few adverse effects at therapeutic dose. It is readily absorbed by oral, sublingual, buccal, vaginal or rectal route. Sublingual route attains quickest concentration. Dose of 400 mcg was chosen in this study to minimise adverse effects with optimal therapeutic benefit. The aim of the study is to determine the efficacy of sublingual misoprostol in reducing caesarean blood loss. MATERIALS AND METHODS It is a prospective experimental study done in VSSIMSAR, Burla. Women undergoing LSCS were randomly assigned to study and control groups of equal strength of 100 each. In all cases, preoperative Hb%, haematocrit, pulse, BP was noted. Study group were given 400 mcg misoprostol at the time of cord clamping. In control group, nothing was given. In all patients, active management of third stage of labour was done by using oxytocin 10 IU (IV along with uterine massage. Blood loss soaked by tetra was calculated using formula, blood loss = wet weight-dry weight/1.05 (1.05 is constant. Amount of blood loss, postoperative Hb%, haematocrit, pulse rate, BP was noted in both groups and compared. BP and pulse were noted after 1 hour and Hb%, haematocrit were noted after 24 hours. RESULTS Study group showed significant decrease in total blood loss (around 117.9 mL as compared to control group. There was significant decrease in the postoperative fall in Hb in the study group as compared to control, the mean difference being 0.631 gm%. Study group also showed decrease in postoperative fall in haematocrit as compared to control, the mean difference being 0.055. CONCLUSION Misoprostol significantly reduced caesarean blood loss and doesn’t affect foetal outcome without significant

    Full Text Available Abstract Background In low-resource settings, where abortion is highly restricted and self-induced abortions are common, access to post-abortion care (PAC services, especially treatment of incomplete terminations, is a priority. Standard post-abortion care has involved surgical intervention but can be hard to access in these areas. Misoprostol provides an alternative to surgical intervention that could increase access to abortion care. We sought to gather additional evidence regarding the efficacy of 400 mcg of sublingual misoprostol vs. standard surgical care for treatment of incomplete abortion in the environments where need for economical non-surgical treatments may be most useful. Methods A total of 860 women received either sublingual misoprostol or standard surgical care for treatment of incomplete abortion in a multi-site randomized trial. Women with confirmed incomplete abortion, defined as past or present history of vaginal bleeding during pregnancy and an open cervical os, were eligible to participate. Participants returned for follow-up one week later to confirm clinical status. If abortion was incomplete at that time, women were offered an additional follow-up visit or immediate surgical evacuation. Results Both misoprostol and surgical evacuation are highly effective treatments for incomplete abortion (misoprostol: 94.4%, surgical: 100.0%. Misoprostol treatment resulted in a somewhat lower chance of success than standard surgical practice (RR = 0.90; 95% CI: 0.89-0.92. Both tolerability of side effects and women’s satisfaction were similar in the two study arms. Conclusion Misoprostol, much easier to provide than surgery in low-resource environments, can be used safely, successfully, and satisfactorily for treatment of incomplete abortion. Focus should shift to program implementation, including task-shifting the provision of post-abortion care to mid- and low- level providers, training and assurance of drug availability. Trial

    A 50-fold disparity in maternal mortality exists between high- and low-income countries, and in most contexts, the single most common cause of maternal death is postpartum hemorrhage (PPH). In Bangladesh, as in many other low-income countries, the majority of deliveries are conducted at home by traditional birth attendants (TBAs) or family members. In the absence of skilled birth attendants, training TBAs in the use of misoprostol and an absorbent delivery mat to measure postpartum blood loss may strengthen the ability of TBAs to manage PPH. These complementary interventions were tested in operations research among 77,337 home births in rural Bangladesh. The purpose of this study was to evaluate TBAs' knowledge acquisition, knowledge retention, and changes in attitudes and practices related to PPH management in home births after undergoing training on the use of misoprostol and the blood collection delivery mat. We conclude that the training was highly effective and that the two interventions were safely and correctly used by TBAs at home births. Data on TBA practices indicate adherence to protocol, and 18 months after the interventions were implemented, TBA knowledge retention remained high. This program strengthens the case for community-based use of misoprostol and warrants consideration of this intervention as a potential model for scale-up in settings where complete coverage of skilled birth attendants (SBAs) remains a distant goal.

    While Pakistan has made progress toward achieving Millennium Development Goal 5 for maternal health, it is unlikely to achieve the target; further, it is also not on track for Millennium Development Goal 4 regarding child health. Two low-cost, temperature stable and life-saving drugs, misoprostol and chlorhexidine, can respectively avert maternal and newborn deaths, and are particularly pertinent for poor and marginalized areas which bear the brunt of maternal and newborn deaths in Pakistan. In response, Mercy Corps led focused advocacy efforts to promote changes in policies, protocols, and regulatory environments for misoprostol (2012-2014) and for chlorhexidine (2014). These short-duration advocacy projects facilitated significant policy gains, such as inclusion of misoprostol and chlorhexidine into province-specific essential drug lists, development and endorsement of clinical protocols for the two drugs by provincial health departments, inclusion of misoprostol into pre-service training curriculum for several health cadres, and application for registration of chlorhexidine (at the concentration required for newborn care) by two pharmaceutical companies. These results were achieved by a consultative and evidence-based process which generated feedback from community members, program implementers, and policymakers, and ultimately put the government in the driver's seat to facilitate change. Community Action Dialogue forums were linked with provincial-level Technical Working Groups and Provincial Steering Committees, who passed on endorsed recommendations to the Health Secretary. The key factors which facilitated change were the identification of champions within the provincial health departments, prioritization of relationship building and follow-up, focus on concrete advocacy aims rather than broad objectives, and the use of multi-stakeholder forums to secure an enabling environment for the policy changes to take root. While these advocacy initiatives resulted in

Misoprostol is an important option for PPH management in setting where oxytocin (the gold standard for PPH prevention and treatment in not available or not feasible to use. For the substantial number of deliveries which take place at home or at lower level heatlh facilities in India, misoprostol pills can be adminstered to prevent PPH. The standard approach using misoprostol is to administer it prophylactically as primary prevention (600 mcg. An alternative strategy could be to administer misoprostol only to those who are at high risk of having PPH i.e. as secondary prevention.This study reports on the relative cost per person of a strategy involving primary versus secondary prevention of PPH using misoprostol. It is based on a randomized cluster trial that was conducted in Bijapur district in Karnataka, India between December 2011 and March 2014 among pregnant women to compare two community-level strategies for the prevention of PPH: primary and secondary. The analysis was conducted from the government perspective using an ingredient approach.The cluster trial showed that there were no significant differences in clinical outcomes between the two study arms. However, the results of the cost analysis show that there is a difference of INR 6 (US$ 0.1 per birth for implementing the strategies primary versus secondary prevention. In India where 14.9 million births take place at sub-centres and at home, this additional cost of INR 6 per birth translates to an additional cost of INR 94 (US$ 1.6 million to the government to implement the primary prevention compared to the secondary prevention strategy.As clinical outcomes did not differ significantly between the two arms in the trial, taking into account the difference in costs and potential issues with sustainability, secondary

    Full Text Available We explored the feasibility of distributing misoprostol tablets using two strategies in prevention of postpartum haemorrhage (PPH among women residing in the Abhoynagar subdistrict of Bangladesh. We conducted a quasiexperimental study with a posttest design and nonequivalent comparison and intervention groups. Paramedics distributed three misoprostol tablets, one delivery mat (Quaiyum’s delivery mat, a packet of five standardized sanitary pads, and one lidded plastic container with detailed counseling on their use. All materials except misoprostol were also provided with counseling sessions to the control group participants. Postpartum blood loss was measured by paramedics using standardized method. This study has demonstrated community acceptability to misoprostol tablets for the prevention of PPH that reduced overall volume of blood loss after childbirth. Likewise, the delivery mat and pad were found to be useful to mothers as tools for assessing the amount of blood loss after delivery and informing care-seeking decisions. Further studies should be undertaken to explore whether government outreach health workers can be trained to effectively distribute misoprostol tablets among rural women of Bangladesh. Such a study should explore and identify the programmatic requirements to integrate this within the existing reproductive health program of the Government of Bangladesh.

    To evaluate the experience of women receiving mifepristone-misoprostol for early induced abortion in public sector facilities in the Federal District of Mexico City. An open-label prospective study was conducted with 1000 pregnant women who sought induced abortion with a pregnancy of up to 63days of gestation, as measured from the date of their last menstrual period. The study was conducted in three public sector healthcare facilities: two secondary level hospitals and one primary care clinic. Women ingested 200mg mifepristone on day 1, followed by 800μg buccal misoprostol 24hours later, and they returned for follow-up on day 8. The primary outcome was complete abortion without recourse to surgical intervention. A total of 971 women received mifepristone-misoprostol and were included in the analysis for efficacy of treatment. The overall efficacy of the combined medical abortion regimen studied was 97.3% (n=945); the success rate did not vary significantly by gestational age (95.9%-100%; P=0.449). Most women (n=922, 95.0%) had a successful induced abortion with only one dose of misoprostol. The combined mifepristone and buccal misoprostol regimen was found to be highly effective and acceptable among Mexican women. www.ClinicalTrials.gov: NCT00386282.

    The clinical effects of dosage during the period of treatment of Lithospermum Ruderale extract-a kind of Chinese traditional herbal medicine-on medicinal abor tion induced by mifepristone and misoprostol were studied. Lithospermum Ruderale extract was administrated 3 d before, 3 d after or 3 d before plus 3 d after the admin istration of misoprostol respectively. The dose of Lithospermum Ruderale extract was 50 g, 75 g or 100g respectively. Thus 1 350 women of early pregnancy were grouped into 9 groups and observed. The results showed that the effects of Lithospermum Rud erale used 3 d before, and 3 d before plus 3 d after (6 days misoprostol were signifi cantly better than those only used 3 d after misoprostol both for complete abortion and bleeding (P<0.05). The dosage between 50 g and l00 g made no significant differ ence in clinical effects. Therefore it is reasonable to use 50 g Lithospermum Ruderale before misoprostol to improve medicinal abortion.

    To explore the availability and provision of misoprostol and other medicines for menstrual regulation (MR) among pharmacies in Bangladesh. Between March and November 2011, a cross-sectional study using mystery client visits was conducted among pharmacy workers in Dhaka and Gazipur Districts, Bangladesh. Mystery clients were trained to present 1 of 4 pre-developed situations to pharmacy workers to elicit information on the regimen, adverse effects, and complications of misoprostol use. Mystery clients visited 331 pharmacies. Among the 331 pharmacy workers, 45.8% offered the mystery clients misoprostol and/or other medicines for MR; 25.7% referred them to private clinics or hospitals. Only 7% recommended an effective regimen of misoprostol for MR; 65% suggested administering vaginal and oral misoprostol together. Overall, 72.4% did not provide any advice on complications; the remainder suggested visiting trained providers for complications. Counseling on excessive bleeding as a danger sign was provided by 46% of pharmacy workers. Most (94%) did not provide or refer for post-MR family planning. Pharmacy workers in urban Bangladesh are providing ineffective drugs and regimens for MR. A training package is needed to strengthen service delivery by providing accurate information, high-quality products, and referral mechanisms for women seeking MR through pharmacies. © 2013.

    Misoprostol, a PGE analog, is an effective radioprotector of murine intestine and hematopoietic and hair cell renewal systems. The radioprotective nature of misoprostol was extended to examine its ability to influence clonogenic cell survival and induction of oncogenic transformation in Syrian hamster embryo cells exposed to X rays in utero and assayed in vitro. Hamsters in their 12th day of pregnancy were injected subcutaneously with misoprostal, and 2 h later the pregnant hamsters were exposed to graded doses of X rays. Immediately after irradiation, hamsters were euthanized and embryonic tissue was explanted into culture dishes containing complete growth medium. After a 2-week incubation period, clongenic cell survival and morphologically transformed foci were determined. Survival of misoprostol-treated SHE cells was increased and yielded a dose reduction factor of 1.5 compared to SHE cells treated with X rays alone. In contrast, radiation-induced oncogenic transformation of misoprostol-treated cells was reduced by a factor of 20 compared to cells treated with X rays alone. These studies suggest that misoprostol not only protects normal tissues in vivo from acute radiation injury, but also protects cells, to a large extent, from injury leading to transforming events. 26 refs., 6 figs., 2 tabs

    Unprotected sexual intercourse between persons residing in or traveling from regions with Zika virus transmission is a risk factor for infection. To model risk for infection after sexual intercourse, we inoculated rhesus and cynomolgus macaques with Zika virus by intravaginal or intrarectal routes. In macaques inoculated intravaginally, we detected viremia and virus RNA in 50% of macaques, followed by seroconversion. In macaques inoculated intrarectally, we detected viremia, virus RNA, or both, in 100% of both species, followed by seroconversion. The magnitude and duration of infectious virus in the blood of macaques suggest humans infected with Zika virus through sexual transmission will likely generate viremias sufficient to infect competent mosquito vectors. Our results indicate that transmission of Zika virus by sexual intercourse might serve as a virus maintenance mechanism in the absence of mosquito-to-human transmission and could increase the probability of establishment and spread of Zika virus in regions where this virus is not present.

    Full Text Available There are a number of disadvantages inherent in all oral hormonal contraceptives: need for daily administration, fluctuations of hormone levels throughout the day, metabolism in the gastrointestinal tract, the effect of the first passage through the liver. All this became a prerequisite to the creation of prolonged oral hormonal methods of contraception, which would be devoid of these shortcomings. One of such method of hormonal contraception is intravaginal hormonal system. The aim was to determine the safety and efficacy of its use in women of reproductive age with overweight. 43 women were included. State of lipid metabolism, changes of the hemostatic system, blood pressure and weight fluctuations in the past 6 months of using intravaginal hormonal contraceptive system were studied. Results. It is established that hormonal intravaginal contraceptive ring gives minimal metabolic effects. Conclusion. This suggests that this ring can be used successfully in patients with excessive body mass, because there is no effect of the ring on hemostasis, lipid metabolism and body weight.

    Women-controlled methods for prevention of male-to-female sexual transmission of HIV-1 are urgently needed. Providing inhibitory concentrations of HIV-1 reverse transcriptase inhibitors to impede the replication of the virus in the female genital tissue offers a mechanism for prophylaxis of HIV-1. To this end, an intravaginal ring device that can provide long duration delivery of dapivirine, a nonnucleoside reverse transcriptase inhibitor of HIV-1, was developed utilizing a medical-grade polyether urethane. Monolithic intravaginal rings were fabricated and sustained release with cumulative flux linear with time was demonstrated under sink conditions for a period of 30 days. The release rate was directly proportional to the amount of drug loaded. Another release study conducted for a week utilizing liposome dispersions as sink conditions, to mimic the partitioning of dapivirine into vaginal tissue, also demonstrated release rates constant with time. These results qualify polyether urethanes for development of intravaginal rings for sustained delivery of microbicidal agents. (c) 2008 Wiley-Liss, Inc. and the American Pharmacists Association

    Full Text Available Objective: Evaluate implementation of misoprostol for postabortion care (MPAC in two African countries. Design: Qualitative, program evaluation. Setting: Twenty-five public and private health facilities in Rift Valley Province, Kenya, and Kampala Province, Uganda. Sample: Forty-five MPAC providers, health facility managers, Ministry of Health officials, and non-governmental (NGO staff involved in program implementation. Methods and main outcome measures: In both countries, the Ministry of Health, local health centers and hospitals, and NGO staff developed evidence-based service delivery protocols to introduce MPAC in selected facilities; implementation extended from January 2009 to October 2010. Semi-structured, in-depth interviews evaluated the implementation process, identified supportive and inhibitive policies for implementation, elicited lessons learned during the process, and assessed provider satisfaction and providers’ impressions of client satisfaction with MPAC. Project reports were also reviewed. Results: In both countries, MPAC was easy to use, and freed up provider time and health facility resources traditionally necessary for provision of PAC with uterine aspiration. On-going support of providers following training ensured high quality of care. Providers perceived that many women preferred MPAC, as they avoided instrumentation of the uterus, hospital admission, cost, and stigma associated with abortion. Appropriate registration of misoprostol for use in the pilot, and maintaining supplies of misoprostol, were significant challenges to service provision. Support from the Ministry of Health was necessary for successful implementation; lack of country-based standards and guidelines for MPAC created challenges. Conclusions: MPAC is simple, cost-effective and can be readily implemented in settings with high rates of abortion-related mortality.

    Purpose: To investigate the efficacy of oral misoprostol administered to facilitate tandem application to the cervix as a part of brachytherapy in patients with cervical cancer. Methods and Materials: Eighty patients with cervical cancer who had been planned to undergo brachytherapy at Dr. Luetfi Kirdar Kartal Training and Research Hospital were evaluated in a double-blind, prospective, randomized trial. Patients were divided randomly into two groups of 40 patients. The first and second groups received 400 μg of misoprostol orally and placebo, respectively, 3 h before tandem application. The two groups were compared in terms of age, diameter of tumor, parity, age at first intercourse, amount of bleeding and pain at first tandem application, length of endometrial cavity measured by hysterometer, and size of Hegar dilators used for cervical dilatation. Results: Of all cases, 63.6%, 16.3%, 10%, 6.3%, 2.5%, and 1.3% were Stage IIB, IIIB, IIIA, IVA, IIA and IIC, respectively. Mean (±SD) age (range) was 49.3 ± 13.1 (25-83) years and 56.6 ± 13.2 (30-78) years in the study and control groups, respectively (p = 0.015). Age at first intercourse, diameter of tumor, parity, amount of bleeding at first tandem application, and length of endometrial cavity measured by hysterometer were not significantly different between the two groups. Pain score was significantly higher in the control group (p < 0.001). Application was significantly easier in the study group compared with controls (p < 0.001). Average size of initial Hegar dilators used for cervical dilatation was significantly higher in the study group compared with controls (p = 0.017). Conclusion: Administration of misoprostol 400 μg orally for cervical ripening before tandem application facilitates the procedure, increases patient tolerability and comfort, and may decrease complication rates.

    To investigate the effect of misoprostol in the reduction of adhesion formation after gynecological surgery. A double blind, randomized controlled experimental study was designed. Twenty-one female Wistar Hannover rats were divided into three groups as control, misoprostol and Hyalobarrier(®) groups. A uterine horn adhesion model was created. After anesthesia induction, 1.5-2cm injuries were made to the each uterine horn by cautery. The control group received no special medications except for the standard surgical procedure. The misoprostol group received 10μcg/kg misoprostol in addition to the standard surgical procedure, and the Hyalobarrier(®) group received 1cm(3) ready-for-use Hyalobarrier(®) gel intraperitoneally in addition to the standard surgical procedure. After 14 days from the first surgical procedure, adhesion scores were evaluated. The extent (p<0.001), severity (p<0.001), degree (p<0.001) and total adhesion score (p<0.001) values of the control group were statistically higher than the values of misoprostol and Hyalobarrier(®) groups. The inflammation score value of misoprostol group was statistically lower than control and Hyalobarrier(®) groups (p<0.001). In this study, we have found a new therapeutic potential of misoprostol that may be useful in preventing pelvic adhesion and reducing inflammation scores. Copyright © 2014 Elsevier Ireland Ltd.

    The purpose of this study was to gather the necessary data to support the design and implementation of a pilot program for women who are unable to deliver in a healthcare facility in the Lao People's Democratic Republic (PDR), by using community distribution of misoprostol to prevent postpartum hemorrhage (PPH). The study builds on an earlier research that demonstrated both support and need for community-based distribution of misoprostol in Lao PDR. This qualitative study identified acceptability of misoprostol and healthcare system needs at varying levels to effectively distribute misoprostol to women with limited access to facility-based birthing. Interviews (n=25) were undertaken with stakeholders at the central, provincial, and district levels and with community members in five rural communities in Oudomxay, a province with high rates of maternal mortality. Focus group discussions (n=5) were undertaken in each community. Respondents agreed that PPH was the major cause of preventable maternal mortality with community distribution of misoprostol an acceptable and feasible interim preventative solution. Strong leadership, training, and community mobilization were identified as critical success factors. While several participants preferred midwives to distribute misoprostol, given the limited availability of midwives, there was a general agreement that village health workers or other lower level workers could safely administer misoprostol. Many key stakeholders, including women themselves, considered that these community-level staff may be able to provide misoprostol to women for self-administration, as long as appropriate education on its use was included. The collected data also helped identify appropriate educational messages and key indicators for monitoring and evaluation for a pilot program. The findings strengthen the case for a pilot program of community distribution of misoprostol to prevent PPH in remote communities where women have limited access to a

    Miller, M.J.; Zhang, x.J.; Gu, x.A.; Clark, D.A.

    1991-01-01

    Acute injury was established in anesthetized rabbits by intraluminal administration of acetic acid with and without bovine casein, into loops of distal small intestine. Damage was quantified after 45 minutes by the blood-to-lumen movement of 51 Cr-labeled ethylenediaminetetraacetic acid (EDTA) and fluorescein isothiocyanate-tagged bovine serum albumin as well as luminal fluid histamine levels. The amount of titratable acetic acid used to lower the pH of the treatment solutions to pH 4.0 was increased by the addition of calcium gluconate. Luminal acetic acid caused a 19-fold increase in 51 Cr-EDTA accumulation over saline controls; casein did not modify this effect. In saline controls, loop fluid histamine levels bordered on the limits of detection (1 ng/g) but were elevated 19-fold by acetic acid exposure and markedly increased (118-fold) by the combination of acid and casein. Intraluminal misoprostol (3 or 30 micrograms/mL), administered 30 minutes before acetic acid, significantly attenuated the increase in epithelial permeability (luminal 51 Cr-EDTA, fluorescein isothiocyanate-bovine serum albumin accumulation) and histamine release (P less than 0.05). Diphenhydramine, alone or in combination with cimetidine, and indomethacin (5 mg/kg IV) were not protective. It is concluded that exposure of the epithelium to acetic acid promotes the transepithelial movement of casein leading to enhanced mast cell activation and mucosal injury. Damage to the epithelial barrier can be prevented by misoprostol

    Acute injury was established in anesthetized rabbits by intraluminal administration of acetic acid with and without bovine casein, into loops of distal small intestine. Damage was quantified after 45 minutes by the blood-to-lumen movement of {sup 51}Cr-labeled ethylenediaminetetraacetic acid (EDTA) and fluorescein isothiocyanate-tagged bovine serum albumin as well as luminal fluid histamine levels. The amount of titratable acetic acid used to lower the pH of the treatment solutions to pH 4.0 was increased by the addition of calcium gluconate. Luminal acetic acid caused a 19-fold increase in {sup 51}Cr-EDTA accumulation over saline controls; casein did not modify this effect. In saline controls, loop fluid histamine levels bordered on the limits of detection (1 ng/g) but were elevated 19-fold by acetic acid exposure and markedly increased (118-fold) by the combination of acid and casein. Intraluminal misoprostol (3 or 30 micrograms/mL), administered 30 minutes before acetic acid, significantly attenuated the increase in epithelial permeability (luminal {sup 51}Cr-EDTA, fluorescein isothiocyanate-bovine serum albumin accumulation) and histamine release (P less than 0.05). Diphenhydramine, alone or in combination with cimetidine, and indomethacin (5 mg/kg IV) were not protective.

    To compare the efficacy and safety of oral misoprostol with prostaglandin E2 vaginal tablets for ripening of cervix and induction of labour at term. Study Design: A non blinded, randomised, controlled trial. Place and Duration of Study: Department of Obstetrics and Gynaecology, Pakistan Air Force Hospital, Air Headquarters Islamabad from July 2005 to January 2006. Patients and Methods: Hundred pregnant women with a singleton live pregnancy, at term (37-42 weeks) with cephalic presentation were selected for induction of labour for various indications having a Bishop's score of < or =5. These women were randomly allocated to receive either 100 micro gm of misoprostol rally repeated four hourly to a maximum of four doses or a 3mg PGE2 tablet vaginally repeated six hourly to a maximum of two doses. Main outcomes measured: Cervical score before and after oral misoprostol and prostaglandin E2 vaginal tablets, vaginal birth within 24 hours of first prostaglandin dose, no of patients having failed induction, caesarean sections (all), caesarean section for fetal distress and uterine hyperstimulation with associated changes in fetal heart rate. Results: Over the period of one year 100 women were recruited for the study, 50 to the misoprostol group and 50 to the vaginal prostaglandin E2 group. There was no significant differences between the two treatment groups in the primary outcomes: improvement in bishops score in both the groups, no of patients with failed induction in both the groups misoprostol 2/50 (4%) v PGE2 3/50 (6%) , vaginal birth achieved in 24 hours (misoprostol 27/50 (54%) v PGE2 29/50 (58%), caesarean sections 14/50 (28%) v 12/50(24%) caesarean section for fetal distress 4/50((8%) v 5/50(9%); uterine hyperstimulation with fetal heart rate changes 2/50 ((4%) v none in the PGE2 group.). Neonatal outcomes were not significantly different in the two groups. Conclusion: Oral misoprostol in strength of 100 micro gm has similar efficacy to vaginal PGE2 tablets

    Although vaginal immunization has been explored as a strategy to induce mucosal immunity in the female reproductive tract, this site displays unique immunological features that probably evolved to inhibit anti-paternal T cell responses after insemination to allow successful pregnancy. We previously demonstrated that estradiol, which induces an estrus-like state, prevented CD8(+) T cell priming during intravaginal immunization of mice. We now show that estradiol prevented antigen loading of vaginal antigen presenting cells (APCs) after intravaginal immunization. Histological examination confirmed that estradiol prevented penetration of peptide antigen into the vaginal wall. Removal of the estradiol-induced mucus barrier by mucinase partially restored antigen loading of vaginal APC and CD8(+) T cell proliferation in vivo. The estradiol-induced mucus barrier may thus prevent exposure to antigens delivered intravaginally, supplementing additional estradiol-dependent mechanism(s) that inhibit CD8(+) T cell priming after insemination or vaginal vaccination.

    Full Text Available Abstract Background Retained placenta is one of the common causes of maternal mortality in developing countries where access to appropriate obstetrical care is limited. Current treatment of retained placenta is manual removal of the placenta under anaesthesia, which can only take place in larger health care facilities. Medical treatment of retained placenta with prostaglandins E1 (misoprostol could be cost-effective and easy-to-use and could be a life-saving option in many low-resource settings. The aim of this study is to assess the efficacy and safety of sublingually administered misoprostol in women with retained placenta in a low resource setting. Methods Design: Multicentered randomised, double-blind, placebo-controlled trial, to be conducted in 5 hospitals in Tanzania, Africa. Inclusion criteria: Women with retained placenta, at a gestational age of 28 weeks or more and blood loss less than 750 ml, 30 minutes after delivery of the newborn despite active management of third stage of labour. Trial Entry & Randomisation & Study Medication: After obtaining informed consent, eligible women will be allocated randomly to the treatment groups using numbered envelopes that will be randomized in variable blocks containing identical capsules with either 800 microgram of misoprostol or placebo. The drugs will be given sublingually. The women, maternal care providers and researchers will be blinded to treatment allocation. Sample Size: 117 women, to show a 40% reduction in manual removals of the placenta (p = 0.05, 80% power. The randomization will be misoprostol: placebo = 2:1 Primary Study Outcome: Expulsion of the placenta without manual removal. Secondary outcome is the number of blood transfusions. Discussion This is a protocol for a randomized trial in a low resource setting to assess if medical treatment of women with retained placenta with misoprostol reduces the incidence of manual removal of the placenta.

    to determine if misoprostol is safe and efficacious in preventing postpartum haemorrhage (PPH) when administered by trained traditional birth attendants (TBA) at home deliveries. a randomised, double-blind, placebo-controlled trial. Chitral, Khyber Pakhtunkhwa Province, Pakistan. a total of 1119 women giving birth at home. from June 2006 to June 2008, consenting women were randomised to receive 600 microg oral misoprostol (n = 534) or placebo (n = 585) after delivery to determine whether misoprostol reduced the incidence of PPH (≥ 500 ml). the primary outcomes were measured blood loss ≥ 500 ml after delivery and drop in haemoglobin >2 g/dl from before to after delivery. oral misoprostol was associated with a significant reduction in the rate of PPH (≥ 500 ml) (16.5 versus 21.9%; relative risk 0.76, 95% CI 0.59-0.97). There were no measurable differences between study groups for drop in haemoglobin >2 g/dl (relative risk 0.79, 95% CI 0.62-1.02); but significantly fewer women receiving misoprostol had a drop in haemoglobin >3 g/dl, compared with placebo (5.1 versus 9.6%; relative risk 0.53, 95% CI 0.34-0.83). Shivering and chills were significantly more common with misoprostol. There were no maternal deaths among participants. postpartum administration of 600 microg oral misoprostol by trained TBAs at home deliveries reduces the rate of PPH by 24%. Given its ease of use and low cost, misoprostol could reduce the burden of PPH in community settings where universal oxytocin prophylaxis is not feasible. Continual training and skill-building for TBAs, along with monitoring and evaluation of programme effectiveness, should accompany any widespread introduction of this drug.

  6. Intravaginal testicular torsion in newborns. To fix or not to fix the contralateral testis?

    Full Text Available Scrotal swelling suggesting testicular torsion is a rare urological emergency which requires a clinical urgent evaluation and most of the times must be managed surgically. In newborns it can occur in the postnatal period, usually within the twenty-eighth day of life, or more frequently in utero, during the descent of the testis into the scrotum. Usually its poor fixedness allows the testis an abnormal mobility inside the scrotum, configuring the framework of extravaginal torsion. On the contrary during the perinatal period a twist that takes place inside the tunica vaginalis, known as intravaginal torsion, is extremely uncommon and only few cases are well documented in the literature. Authors present a rare case of intravaginal testicular torsion occurred in perinatal period. In this situation only the early surgical exploration of the scrotum may allow the rescue of the gonad, although in rare cases. Timing of surgical treatment and need for contralateral testicular fixation remain controversial. However since the anatomical defect of the tunica vaginalis can be bilateral the surgical fixation even of the contralateral testis is important, now or later, in order to prevent any future torsion of this gonad. The authors also present a brief review of recent literature on the subject.

    The objective of the study is to evaluate the acceptability of the intravaginal administration of ovules/suppositories of DHEA (dehydroepiandrosterone, prasterone) for the treatment of vulvovaginal atrophy (VVA) in women with moderate to severe dyspareunia who were administered daily for 12 weeks intravaginal 0.50% (6.5 mg) DHEA or placebo. There were a total of 373 women in the per-protocol population who responded to the questionnaire for both treatment groups. While it was planned that the applicator would be evaluated as suitable if at least 80% of participants have a global score  ≤ 2 units, 99% and 100% of participants had a score  ≤ 2 units in the placebo and DHEA groups, respectively, for the global score (mean of 5 questions). When asked about like and dislike the technique of drug administration, 284 comments were positive, while 114 women gave no comment. About 92-94% of women indicated that they were very confident to be able use the applicator successfully in the future. The survey shows a high degree of satisfaction and of confidence to use the applicator successfully in the future.

    We describe the engineering of a degradable intravaginal ring (IVR) for the delivery of the potent HIV-1 reverse transcriptase inhibitor dapivirine. The degradable polymer used in fabricating the device incorporated poly(caprolactone) ester blocks in a poly(tetramethylene ether) glycol ABA type polyurethane backbone. The polymer was designed to maintain its structure for 1 month during usage and then degrade in the environment post-disposal. In vitro release of dapivirine showed zero-order kinetics for up to 1 month and significant levels of drug release into engineered vaginal tissue. The mechanical properties of the degradable IVR were comparable to those of a widely used contraceptive intravaginal ring upon exposure to simulated vaginal conditions. Incubation under simulated vaginal conditions for a month caused minimal degradation with minimal effect on the mechanical properties of the ring and polymer. The cytotoxicity evaluation of the drug-loaded IVRs against Vk2/E6E7 human vaginal epithelial cells, Lactobacillus jensenii, and engineered vaginal tissue constructs showed the degradable polyurethane to be non-toxic. In vitro evaluation of inflammatory potential monitored through the levels of inflammatory cytokines IL-8, IL-1α, IL-6, IL-1β, and MIP-3α when engineered EpiVaginal™ tissue was incubated with the polyurethanes suggested that the degradable polyurethane was comparable to commercial medical grade polyurethane. These results are encouraging for further development of this degradable IVR for topical vaginal delivery of microbicides.

    Virtually all efforts to generate an effective protection against the life-long, recurrent genital infections caused by Herpes simplex virus-2 (HSV-2) have failed. Apart from sexual transmission, the virus can also be transmitted from mothers to neonates, and is a key facilitator of HIV co-acquisition. Here, we uncover a nanoimmunotherapy using specially designed Zinc Oxide Tetrapod Nanoparticles (ZOTEN) with engineered oxygen vacancies. We demonstrate that ZOTEN, when used intravaginally as a microbicide, is an effective suppressor of HSV-2 genital infection in female BALB/c mice. The strong HSV-2 trapping ability of ZOTEN significantly reduced the clinical signs of vaginal infection and effectively decreased animal mortality. In parallel, ZOTEN promoted the presentation of bound HSV-2 virions to mucosal antigen presenting cells, enhancing T cell- mediated and antibody-mediated responses to the infection, and thereby, suppressing a re-infection. We also found that ZOTEN exhibits strong adjuvant-like properties, which is highly comparable to alum, a commonly used adjuvant. Overall, our study provides very first evidence for the protective efficacy of an intravaginal microbicide/vaccine or microbivac platform against primary and secondary female genital herpes infections.

    Objective: To compare the results of induction of labour with misoprostol (PGE1 analogue) with dinoprostone (PGE2 analogue) in terms of induction delivery interval, mode of delivery, and the need for oxytocin augmentation. Setting: Department of Obstetrics and Gynaecology, Combined Military Hospital, Rawalpindi. Duration of Study: Six months Study Design: Randomized controlled trial. Subject and Method: Total 100 subjects were included in this study. These patients were divided in groups-A and B. Group-A was induced with prostin tablet i.e. dinoprostone PGE2 3 mg tablets maximum of 2 doses, 6 hours apart. Group-B induced with prosotec 50 mu gm 4 hourly, 4 doses. The subjects were full term pregnant women who were either primigravida, 2nd or 3rd gravid and had bishop score less than 5. Results: The patients included in the study were between the ages of 19 to 37 years. The mean age of group-A was 26.72 +- 4.62 years and of group-B was 28.4 +- 4.94 years (p value > 0.05). All the patients in both groups were between 37 to 42 weeks of gestation. The mean gestational age of group-A was 39.74 +- 2.09 weeks and in group-B it was 39.62 +- 1.55 weeks (p > 0.05). Oxytocin augmentation was required in late 1st stage and 2nd stage in group-A in 68% cases but it was required in only 30% cases in group-B cases. The maximum duration of labour was more than 11 hours in 24% cases in group-A but only 6% in group-B. Conclusion: Misoprostol (PGE1 analogue) is a useful drug for labour induction. There is short induction delivery interval and reduced need for the use of oxytocin augmentation. There are also less failure rates of induction with misoprostol. Rate of instrumental delivery and caesarean section is also less. (author)

    To compare the safety and efficacy of Misoprostol through oral and vaginal routes for induction of labour at term. Quasi-experimental study. Eighty term patients who met the inclusion criteria were selected for induction of labour with (50 macro g) Misoprostol, either by oral or vaginal route. The patients were allocated in two groups-A and B, using non-probability convenient sampling technique. The dose was repeated at an interval of 6 hours upto maximum dose of 150 macro g. Improvement in Bishop's score, analgesic requirements, route of delivery, maternal complications, neonatal outcomes were noted. The commonest indication in group-A was premature rupture of membranes in 16 patients (40%) and in 8 (20%) patients of group-B. Mean improvement in Bishop's score after 6 hours was greater in group-A (3.6 + 3.09) than group-B (3.3 + 3.45, p=0.70). Induction to delivery interval was less in group-A (6.7 + 4.4 hours) than group-B (7.5 + 4.3 hours, p=0.41). Oxytocin augmentation was required more in group-B as compared to group-A. Normal vaginal deliveries were achieved in 95% of group-A and in 80% of group-B. The dose of 50 macro g was effective in 31(77.5%) patients of group-A as compared to 24 (60.0%) patients of group-B, while 100 macro g was needed in 6 (15.0%) patients of group-A as compared to 13 (32.5%) patients in group-B. There was no significant difference between both the groups with regard to analgesic requirement, instrumental delivery, maternal complications and neonatal outcome. Safety and efficacy was comparable between low-dose vaginal and oral Misoprostol uses for induction of labour. However, oral route was better with respect to treatment interval, number of doses required and route of delivery. Both routes of administration can alternatively be used for induction of labour in developing countries where cost of drug does matter. (author)

    Purpose: Acute radiation proctitis is the most relevant complication of pelvic radiation and is still mainly treated supportively. Considering the negative impact of acute proctitis symptoms on patients' daily activities and the potential relationship between the severity of acute radiation injury and late damage, misoprostol was tested in the prevention of acute radiation-induced proctitis. Methods and Materials: A total of 100 patients who underwent radiotherapy for prostate cancer were entered into this phase III randomized, placebo-controlled, double-blind study with misoprostol or placebo suppositories. Radiation-induced toxicity was evaluated weekly during radiotherapy using the Common Toxicity Criteria. Results: Between the placebo and the misoprostol groups, no significant differences in proctitis symptoms occurred: 76% of patients in each group had Grade 1 toxicity, and 26% in the placebo group and 36% in the misoprostol group had Grade 2 toxicity. No differences were found in onset or symptom duration. Comparing the peak incidence of patients' toxicity symptoms, significantly more patients experienced rectal bleeding in the misoprostol group (p = 0.03). Conclusion: Misoprostol given as a once-daily suppository did not decrease the incidence and severity of radiation-induced acute proctitis and may increase the incidence of acute bleeding

    Purpose: We reviewed our experience with out patient high dose rate (HDR) intravaginal irradiation given post-operatively in endometrial cancer to assess local control, survival, and toxicity when used alone or in combination with external beam irradiation. Methods and Materials: From (12(88)) to (12(92)), 78 patients underwent TAH/BSO and received post-operative HDR intravaginal irradiation for endometrial cancer. Pathologic stage distribution was IB/IC: 56%, II: 22%, III: 22%. Adjuvant therapy was given in one of three schemes: HDR vaginal radiation alone (6 weekly fractions of 500 cGy prescribed 5 mm from the applicator surface treating the upper 4 cm of the vagina), pelvic irradiation with vaginal HDR (500 cGy x 4 weekly fractions) or whole abdomen/pelvic irradiation (WAPI) with vaginal HDR treatment (500 cGy x 3 weekly fractions). Prior to the first HDR vaginal treatment, a simulation with placement of vaginal apex metallic markers was performed to assure proper positioning of the intravaginal cylinders. Pelvic midline blocking was designed from the HDR intravaginal simulation films. The 55 patients who underwent combined external beam irradiation/brachytherapy received a median dose to the pelvis of 5040 cGy (range 25.2-51.6 Gy), and a median total vaginal dose of 5060 cGy (range 30.0-57.6 Gy). Results: Median follow-up is 37 months (range 6-73 months). Local control (vaginally) is 98.7%. The one vaginal failure was in the distal vagina, outside the treatment volume. All other failures (4) were distant with the vagina controlled [3 intra-abdominal and one bone/intra-abdominal]. For stages I and II, the disease free survival is 92.8%. For stage III the disease free survival is 86.5%. Median overall time to failure is 14.3 months (range 8.5-18.6 months). In terms of acute toxicity, no grade 3-4 acute toxicity of the vagina or bladder was seen. However, 9% acute GI toxicity was encountered. Chronic grade 1-2 toxicities included: vaginal 21.8% (foreshortening and

    Complications following spontaneous or induced abortion are a major cause of maternal morbidity. To manage these complications, post-abortion care (PAC) services should be readily available and easy to access. Standard PAC treatment includes surgical interventions that are highly effective but require surgical providers and medical centers that have the necessary space and equipment. Misoprostol has been shown to be an effective alternative to surgical evacuation and can be offered by lower level clinicians. This study sought to assess whether 400 mcg sublingual misoprostol could effectively evacuate the uterus after incomplete abortion and to confirm its applicability for use at lower level settings. All women presenting with incomplete abortion at one of three hospitals in Vietnam were enrolled. Providers were not asked to record if the abortion was spontaneous or induced. It is likely that all were spontaneous given the legal status and easy access to abortion services in Vietnam. Participants were given 400 mcg sublingual misoprostol and instructed to hold the pills under their tongue for 30 minutes and then swallow any remaining fragments. They were then asked to return one week later to confirm their clinical status. Study clinicians were instructed to confirm a complete expulsion clinically. All women were asked to complete a questionnaire regarding satisfaction with the treatment. Three hundred and two women were enrolled between September 2009 and May 2010. Almost all participants (96.3%) had successful completions using a single dose of 400 mcg misoprostol. The majority of women (87.2%) found the side effects to be tolerable or easily tolerable. Most women (84.3%) were satisfied or very satisfied with the treatment they received; only one was dissatisfied (0.3%). Nine out of ten women would select this method again and recommend it to a friend (91.0% and 90.0%, respectively). This study confirms that 400 mcg sublingual misoprostol effectively evacuates

    Post partum hemorrhage still remains a major cause of maternal morbidity and mortality in developing countries. Most of oxytocics like methylergometrine require parenteral administration, which requires special storage. Misoprostol is thermo stable, has a long shelf life and is widely recommended for prevention of postpartum hemorrhage. This can be a choice of oxytocic in developing countries like ours, where storage facilities and resources are limited. Objectives: To compare efficacy of sublingual Misoprostol versus intramuscular Methylergometrine in prevention of primary postpartum hemorrhage after delivery. Study Design: Quasi experimental study Place and Duration of Study: Department of Gynae/Obs, Military Hospital and Combined Military Hospital Rawalpindi cantt. December 2007 to July 2008. Material and Methods: One hundred and thirty six pregnant ladies were selected. On arrival each patient was examined thoroughly along with baseline investigations. Therapeutic option was allocated to the patients simply by using a table of random numbers and dividing them in two equal groups. Informed written consent was taken. Each patient was observed for blood loss estimation and hematocrit drop. All the data was analyzed using SPSS version 10.0. Mean +- SD for age, pre-delivery and post-delivery hematocrit, percentage of drop in hematocrit and blood loss during labour was calculated. Results: Mean drop of hematocrit and blood loss were compared among two groups. At the end, it was revealed that there was no significant difference among two groups in blood loss (p=0.49) and hematocrit drop (p=0.14). Conclusion: There is no significant better effect in preventing post partum hemorrhage among the two drugs. (author)

The study builds on an earlier research that demonstrated both support and need for community-based distribution of misoprostol in Lao PDR.Methods: This qualitative study identified acceptability of misoprostol and healthcare system needs at varying levels to effectively distribute misoprostol to women with limited access to facility-based birthing. Interviews (n=25 were undertaken with stakeholders at the central, provincial, and district levels and with community members in five rural communities in Oudomxay, a province with high rates of maternal mortality. Focus group discussions (n=5 were undertaken in each community.Results: Respondents agreed that PPH was the major cause of preventable maternal mortality with community distribution of misoprostol an acceptable and feasible interim preventative solution. Strong leadership, training, and community mobilization were identified as critical success factors. While several participants preferred midwives to distribute misoprostol, given the limited availability of midwives, there was a general agreement that village health workers or other lower level workers could safely administer misoprostol. Many key stakeholders, including women themselves, considered that these

    Dendrimers are emerging as promising topical antimicrobial agents, and as targeted nanoscale drug delivery vehicles. Topical intravaginal antimicrobial agents are prescribed to treat the ascending genital infections in pregnant women. The fetal membranes separate the extra-amniotic space and fetus. The purpose of the study is to determine if the dendrimers can be selectively used for local intravaginal application to pregnant women without crossing the membranes into the fetus. In the present study, the transport and permeability of PAMAM (poly(amidoamine)) dendrimers, across human fetal membrane (using a side-by-side diffusion chamber), and its biodistribution (using immunofluorescence) are evaluated ex-vivo. Transport across human fetal membranes (from the maternal side) was evaluated using Fluorescein (FITC), an established transplacental marker (positive control, size~ 400 Da) and fluorophore-tagged G4-PAMAM dendrimers (~ 16 kDa). The fluorophore-tagged G4-PAMAM dendrimers were synthesized and characterized using 1H NMR, MALDI TOF-MS and HPLC analysis. Transfer was measured across the intact fetal membrane (chorioamnion), and the separated chorion and amnion layers. Over a five hour period, the dendrimer transport across all the three membranes was less than transport of FITC was relatively fast with as much as 49% transport across the amnion. The permeability of FITC (7.9 × 10-7 cm2/s) through the chorioamnion was 7-fold higher than that of the dendrimer (5.8 × 10-8 cm2/s). The biodistribution showed that the dendrimers were largely present in interstitial spaces in the decidual stromal cells and the chorionic trophoblast cells (in 2.5 to 4 h) and surprisingly, to a smaller extent internalized in nuclei of trophoblast cells and nuclei and cytoplasm of stromal cells. Passive diffusion and paracellular transport appear to be the major route for dendrimer transport. The overall findings further suggest that entry of drugs conjugated to dendrimers would be

The nanomedicine was formulated into a vaginal gel to provide ease in self-administration and to enhance retention within the vaginal tract. SQV-encapsulated nanoparticles (SQV-NPs were prepared from poly(lactic-co-glycolic acid(PLGA and conjugated to antihuman anti-CD4 antibody. Antibody-conjugated SQV-NPs (Ab-SQV-NPs had an encapsulation efficiency (EE% of 74.4% ± 3.7% and an antibody conjugation efficiency (ACE% of 80.95% ± 1.10%. Over 50% of total loaded SQV was released from NPs over 3 days. NPs were rapidly taken up by Sup-T1 cells, with more than a twofold increase in the intracellular levels of SQV when delivered by Ab-SQV-NPs in comparison to controls 1 hour post-treatment. No cytotoxicity was observed when vaginal epithelial cells were treated for 24 hours with drug-free Ab-NPs (1,000 µg/mL, 1% HEC placebo gel (200 mg/mL, or 1% HEC gel loaded with drug-free Ab-NPs (5 mg NPs/g gel, 200 mg/mL of gel mixture. Overall, we described an intravaginal nanomedicine that is nontoxic and can specifically deliver SQV into CD4+ immune cells. This platform may demonstrate potential utility in its application as postexposure prophylaxis for the treatment or reduction of HIV infection, but further studies are required.

    Microbicides may prevent HIV and sexually transmitted infections (STIs) in women; however, determining the optimal means of delivery of active pharmaceutical ingredients remains a major challenge. We previously demonstrated that a vaginal gel containing the non-nucleoside reverse transcriptase inhibitor MIV-150 partially protected macaques from SHIV-RT (simian/HIV reverse transcriptase) infection, and the addition of zinc acetate rendered the gel significantly protective. We test the activity of MIV-150 without the addition of zinc acetate when delivered from either ethylene vinyl acetate (EVA) or silicone intravaginal rings (IVRs). MIV-150 was successfully delivered, because it was detected in vaginal fluids and tissues by radioimmunoassay in pharmacokinetic studies. Moreover, EVA IVRs significantly protected macaques from SHIV-RT infection. Our results demonstrate that MIV-150-containing IVRs have the potential to prevent HIV infection and highlight the possible use of IVRs for delivering drugs that block HIV and other STIs.

    In patients with posthysterectomy prolapse of the vaginal vault, the posterior intravaginal slingplasty (posterior IVS, Tyco Healthcare, USA) has been suggested as an alternative to traditional vaginal vault suspensions. The goal of this technique is to recreate the uterosacral ligaments and to reinforce the rectovaginal fascia with the use of prosthetic material. We report the case of a 53-year-old woman with a history of 27 months of perineal suppurative discharge after she underwent a vaginal vault prolapse and rectocele repair using a posterior IVS (Tyco Healthcare, USA). The IVS tape was reinforced by interposing a rectovaginal monofilament polypropylene mesh (Parietex, Sofradim, France). Imaging studies and surgical exploration confirmed infection of the IVS mesh with the formation of a gluteo-vaginal fistula while the rectovaginal mesh was intact.

    The goal of this work was to investigate, to what extent the platelet sensitivity in comparison to prostacyclin (PGI 2 ) should be seen as a responsible factor in the increase of the thrombosis rate. For this blood was examined from 22 patients with corpus carcinoma who had received an intravaginal Radium implant with a radiation dose of 960 mgeh to over 24 h. These patients were compared to a control group of 21 clinically healthy women. Even before the radiation therapy there was an increased aggregation rate of the thrombocytes in the carcinoma patients as well as a reduced sensitivity to PGI 2 . Under irradiation there was an even greater decrease in the sensitivity of the thrombocytes to PGI 2 . The aggregation speed increase statistically significantly and the number of thrombocytes decreased during the Radium irradiation. After the giving of heparin the sensitivity of the thrombocytes to PGI 2 sank strongly. (orig./MG) [de

    Misoprostol is reported to prevent non-steroidal anti-inflammatory drug (NSAID)-associated gastroduodenal complications. There is, however, limited information regarding the efficacy of DA-9601 in this context. We performed a comparative study on the relative efficacy of DA-9601 and misoprostol for prevention of NSAID-associated complications. In this multicenter, double-blinded, active-controlled, stratified randomized, parallel group, non-inferiority trial, 520 patients who were to be treated with an NSAID (aceclofenac, 100 mg, twice daily) over a 4-week period were randomly assigned to groups for coincidental treatment with DA-9601 (60 mg, thrice daily) (236 patients for full analysis) or misoprostol (200 μg, thrice daily) (242 patients for full analysis). [corrected]. The primary endpoint was the gastric protection rate, and secondary endpoints were the duodenal protection rate and ulcer incidence rate. Endpoints were assessed by endoscopy after the 4-week treatment period. Drug-related adverse effects, including gastrointestinal (GI) symptoms, were also compared. At week 4, the gastric protection rates with DA-9601 and misoprostol were 81.4 % (192/236) and 89.3 % (216/242), respectively. The difference between the groups was -14.2 %, indicating non-inferiority of DA-9601 to misoprostol. Adverse event rates were not different between the two groups; however, the total scores for GI symptoms before and after administration were significantly lower in the DA-9601 group than in the misoprostol group (-0.2 ± 2.8 vs 1.2 ± 3.2; p DA-9601 is as effective as misoprostol in preventing NSAID-associated gastroduodenal complications, and has a superior adverse GI effect profile.

    Objective To compare the effects of 2 dosage-forms (granular and decoction) of Arnebia euchroma (royle) Johnst (Arnebia EJ in short below) on medical abortion with that of mifepristone combined with misoprostol Methods Totally 648 women, who had pregnancy of 38-45 d and were willing to terminate pregnancy with mifepristone and misoprostol, were randomly divided into 3groups, each of which was respectively given granular of Arnebia E J, placebo granular,or decoction of Arnebia EJ besides mifepristone and misoprostol. The abortion results,bleeding duration, menstruation recovery and side-effects were observed.Results Neither complete abortion rates nor average bleeding durations of the granular group and the decoction group were significantly different (P>0. 05). The complete abortion rate and bleeding duration of the two groups were respectively higher and shorter than those of the placebo group (P<0. 05). However, the menstruation recovery was not significantly different among the three groups (P>0. 05). The decoctionof Arnebia EJ caused significantly more nausea and vomiting than the other groups (P<0. 05).Conclusion The granular form did not have the odor of Arnebia E J, and caused much less nausea and vomiting compared with the decoction form. The granular and decoction forms were equally effective in improving the results of medical abortion. Therefore it is necessary to conduct further studies on the granular form of Arnebia EJ.

  6. Intravaginal boric acid: is it an alternative therapeutic option for vaginal trichomoniasis?

    2017-12-09

    Trichomoniasis, caused by Trichomonas vaginalis (TV), is the most common curable sexually transmitted infection worldwide. Current guidance in the UK is to treat TV with a nitroimidazole antibiotic. The high prevalence of TV, high rate of antibiotic resistance and limited tolerability to nitroimidazoles suggest that alternative treatment regimens are needed. Intravaginal boric acid (BA) has been used safely for the treatment of candida vulvovaginitis and bacterial vaginosis, and in vitro studies suggest BA is active against TV. We review the evidence for the efficacy of BA in patients with TV. MEDLINE, EMBASE, CINAHL, AMED, HMIC and BNI and Grey literature databases, The Cochrane Library, Trial Registers, conference abstracts and proceedings were searched. Inclusion criteria were women aged 16 years or over with microbiological confirmation of TV infection and using BA as treatment. There were no restrictions on language, publication date or study design. The in vitro evidence for BA activity against TV was also reviewed. No randomised controlled trials or case series were found. Four case reports demonstrated TV clearance with BA using a variety of dose regimens (dose 600 mg alternate nights to 600 mg two times per day; duration 1-5 months). In vitro studies suggest that BA has activity against TV which is independent of its effect on pH. Further evaluation of BA for the treatment of uncomplicated TV is required, but it may be useful when therapeutic options are limited. If shown to be safe and effective, intravaginal BA might provide a well-tolerated alternative anti-infective treatment which reduces community exposure to systemic antibiotics. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Background: Artificial labor pain always poses the risk of fetal distress and is more painful than spontaneous labour. The pharmacological agents that are involved in stimulating uterine contraction may initiate a chain of processes that may lead the baby to suffocate, being deficient of essential oxygen and suffer from distress. The accelerated efforts to adapt safe and advanced measures are inevitable to make the labour induction easier and more secure for both lives involved. Objective: The objective of this study was to compare the incidence of fetal distress in 6 hourly vaginally administered 3 doses, of misoprostol versus dinoprostone for labour induction. Methods: This observational type of comparative study was conducted in Obstetrics Ward Lady Aitchison Hospital Lahore. A total of 200 postdate primigravidas undergoing induction of labour at 41 weeks were selected for this study. They were randomly divided into misoprostol and dinoprostone group, each containing 100 patients. The dose of misoprostol was 50 microgram each time up to a maximum of 150 microgram (3 doses) and dose of dinoprostone was 2 mg and only 2 doses of dinoprostone were used with an interval of 6 hours. Continuous fetal heart rate monitoring was done after induction. Signs of fetal distress like meconium staining of liquor after rupture of membranes and CTG changes were noted. After delivery of baby Apgar score at 5 minutes was taken and any resuscitation required or need for keeping the baby in nursery was noted. Results: The mean age of the patients in misoprostol group was 25.4+-4.5 years and in dinoprostone group was 23.3+-3.4 years. The mean duration of induction to delivery interval in misoprostol group was 16.4+-6.4 hours and in dinoprostone group was 13.1+-4.6 hours. In misoprostol group, 40 (40%) patients delivered with LSCS and 60 (60%) patients delivered with spontaneous vaginal delivery. In dinoprostone group, 36 (36%) patients delivered with LSCS and 64 (64%) patients

    To determine the feasibility and acceptability of providing clean birth kits (CBKs) containing misoprostol for self-administration in a rural setting in Papua New Guinea. A prospective intervention study was conducted between April 8, 2013, and October 24, 2014. Eligible participants were women in the third trimester of pregnancy who attended a prenatal clinic in Unggai Bena. Participants received individual instruction and were then given a CBK containing 600μg misoprostol tablets for self-administration following an unsupervised birth if they could demonstrate their understanding of correct use of items in the CBK. Data regarding the use and acceptability of the CBK and misoprostol were collected during postpartum follow-up. Among 200 participants, 106 (53.0%) had an unsupervised birth, and 99 (93.4%) of these women used the CBK. All would use the CBK again and would recommend it to others. Among these 99 women, misoprostol was self-administered by 98 (99.0%), all of whom would take the drug again and would recommend it to others. The findings strengthen the case for community-based use of misoprostol to prevent postpartum hemorrhage in remote communities. Large-scale interventions should be planned to further evaluate impact and acceptability. Copyright © 2016 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

    Poland syndrome has been attributed to a process of vascular disruption, and exposure to misoprostol at 6-8 weeks of gestation has been shown to produce defects attributed to vascular disruption. Herein we report the first case of a patient with Poland syndrome associated with an aberrant subclavian artery and vascular abnormalities of the retina, whose mother used misoprostol during pregnancy. A White boy of 1 year and 7 months of age, whose mother used misoprostol during the second month of pregnancy, presented with bilateral epicanthal folds, aplasia of the sternocostal head of the pectoralis major muscle with a hypoplastic nipple on the right side, and asymmetry between the upper limbs. The results of an angiotomographic study showed the presence of an aberrant right subclavian artery. Ultrasonographic evaluation showed turbulence and a high peak in the diastolic velocity in both carotid arteries, suggesting stenosis. Ophthalmologic assessment disclosed an intense bilateral tortuosity of the retinal blood vessels, with arterialnarrowing and rarefaction of the retinal pigment epithelium. This case suggests that the mechanism of vascular disruption of misoprostol could be related to the aberrant subclavian artery and the observed Poland syndrome. His retinal findings are different from those in cases described thus far in the literature, and this pattern of anomaly has never been associated with a gestational exposure to misoprostol. The possibility of a relationship of the aberrant right subclavian artery and the pattern of blood flow verified in the carotid arteries with the eye fundus abnormalities could be causally related or simply coincidental.

    To evaluate different imaging protocols, especially with respect to radio frequency (RF) receiver coil location, for Their suitability in providing least squares derived quantitative T 2 values of ovarian follicular fluid for investigations of basic ovarian physiology. Methods: The ovaries of 10 women were imaged via magnetic resonance imaging (MRI) using externally positioned and intravaginally placed RF receiver coils. Half-Fourier acquisition with single-shot turbo spin-echo (HASTE), multiple-echo T 2 , Dixon, turbo spin-echo, and 3-dimensional (3D) fast imaging with steady-state precession (FISP) and time-reversed FISP (PSIF) sequences were used. Quantitative T 2 nuclear spin relaxation rate information from the ovarian follicles between data acquired with the external and intravaginal coils were compared. Additionally, the amount of ovarian follicle and corpora lutea structural detail visible was qualitatively assessed. Results: The T 2 computations indicated that there was no difference in the follicular fluid T 2 values or in the heterogeneity (spatial variance) of the T 2 values between data acquired with the external RF coil and date acquired with the intravaginal RF coil. The best sequences for the visualization of ovarian internal structure were the 3D PSIF sequences and the multiple-echo T 2 -weighted images, confirming our earlier imaging work on excised cow ovaries. Conclusion: It is best to use an externally placed RF coil for quantitative MRI study of ovarian physiology given the lack of difference in quantitative T 2 information and the difficulty associated with imaging the ovaries using an intravaginal RF probe.

    Intravaginal DHEA (dehydroepiandrosterone, prasterone), the exclusive precursor of androgens and estrogens in postmenopausal women, has previously been shown to improve all the domains of sexual function by a strictly local action in the vagina. The well recognized female sexual function index (FSFI) questionnaire was used in the present study. The long-term effect of 52-week treatment with daily intravaginal 0.50% (6.5 mg) DHEA was evaluated on the various domains of female sexual function using the FSFI questionnaire at baseline, Week 26 and Week 52. One hundred and fifty-four postmenopausal women with at least one mild to severe symptom of vulvovaginal atrophy (VVA) and who have completed the FSFI questionnaire at baseline and at least one post-baseline timepoint were included in the analysis. The FSFI domains desire, arousal, lubrication, orgasm, satisfaction and pain were increased by 28%, 49%, 115%, 51%, 41% and 108%, respectively (p<0.0001 for all parameters) at 52 weeks vs. baseline, while the total score was increased from 13.4±0.62 at baseline to 21.5±0.82 (+60%, p<0.0001) at 52 weeks. As the serum levels of DHEA and all its metabolites, including estradiol and testosterone, show no meaningful change, the present clinical data indicate a stimulatory effect of intravaginal DHEA through a strictly local action in agreement with the preclinical data showing that the androgens made locally from DHEA in the vagina induce an increase in local nerve density.

    The primary goal of this study was to compare the effects of 5% ethylene glycol (EG) and 5% glycerol (G) on fertility of frozen-thawed dog semen following intravaginal insemination. The sperm-rich fraction of the ejaculate of three male dogs was collected, pooled and divided into two aliquots, and then frozen with a Tris-glucose-egg yolk-citric acid extender containing either 5% G or 5% EG. A total of 10 bitches were inseminated twice, five with G-frozen-thawed semen and five with EG-frozen-thawed semen; intravaginal inseminations were performed the 4th and the 5th day after the estimated LH peak; four straws, thawed in a 37 degrees C water bath for 1 min and diluted in a Tris buffer, were used for insemination (200 x 10(6) spermatozoa); the insemination dose was introduced in the cranial vagina of the bitch using a sterile plastic catheter. Ovariohysterectomy was performed in all bitches between days 29 and 31 after the calculated LH surge, and pregnancy status, and the number of conceptuses and corpora lutea were recorded. All bitches were pregnant. Neither the number of conceptuses, nor the ratio of conceptuses to corpora lutea (conception rate) was significantly different between groups. In this first screening, with a limited number of bitches, EG-frozen semen did not show a higher fertility than G-frozen semen when used for two intravaginal inseminations. Irrespective of the semen used, conception rate was 0.50.

Results showed an increase in frequency of ALA formation in infected and MPL-treated mice only at 2 days p.i. (P=0.03. A significant diminution in the size of trophozoites was detected in abscesses from mice independently of MPL treatment (from 5.8±1.1 µm at 2 days p.i. to 2.7±1.9 µm at 7 days p.i. compared with trophozoites dimensions observed in susceptible hamsters (9.6±2.7 µm (P<0.01. These results suggest that MPL treatment may modify the adequate control of inflammatory process to allow the persistence of trophozoites in the liver; however, natural resistance mechanisms cannot be discarded.

    Full Text Available Introduction & Objective: In developing countries, postpartum hemorrhage is one of the preventable causes of maternal mortality. The aim of this study is comparison of the effect of rectal misoprostol and intramascular syntometerine in the prevention of postpartum hemorrhage. Materials & Methods: This study was a double blind randomized clinical trial and carried on 200 pregnant women referred to Shabiehkhani maternity center in 2010. The first group received 1ml intramuscular syntometrine and the second group received 600 µg misoprostol rectal suppository after placental delivery. The two groups were matched for confounding variables. All of the study subjects were followed up for 24hrs and their blood pressure, pulse rate, uterine tone, before and after delivery hemoglobin, need to additional uterotonic drugs and drug side effects were evaluated and the results were recorded in an information sheet. Finally all the data were entered into SPSS software and analyzed with statistical tests. Results: The mean age of subjects was 25.61±4.75 years, mean gestational age was 38.8±1.2 weeks, and Mean neonatal birth weight was 3346.2±349.56 grams. The mean fall in hemoglobin level in misorostol group was significantly lower than in syntometrin group (P=0.009. But there weren't any significant differences between the two groups in uterine tone, blood pressure, and pulse rate and also in drug side effects. Conclusion: In this study we demonstrated that rectal misoprostol suppository was more effective than injection syntometrin in decreasing postpartum hemorrhage. Thus, it can be used as a choice drug for third stage management (Sci J Hamadan Univ Med Sci 2011;18(2:38-44

    We present the design of an electronically controlled drug delivery system. The intravaginally located device is a low-invasive platform that can measure and react inside the cow vagina while providing external control and monitoring ability. The electronics manufactured from off the shelf components occupies 16 mL of a Theratron syringe. A microcontroller reads and logs sensor data and controls a gascell. The generated gas pressure propels the syringe piston and releases the formulation. A two way radio link allows communication between other devices or a base station. Proof of principle experiments confirm variable-rate, arbitrary profile drug delivery qualified by internal sensors. A total volume of 30 mL was dispensed over a 7-day-period with a volume error of +/- 1 mL or +/- 7% for larger volumes. Delivery was controlled or overridden via the wireless link, and proximity to other devices was detected and recorded. The results suggest that temperature and activity sensing or social grouping determined via proximity can be used to detect oestrus and trigger appropriate responses.

    The aim of this study was to describe by MRI, in dynamic conditions at rest and straining, the anatomical modifications induced by a commercially available intravaginal device (IVD) aimed at relieving female stress urinary incontinence. Ten female patients complaining of stress urinary incontinence (SUI) had pelvic MRI with static and dynamic sequences, without and with a self-inserted IVD. We studied positions and angulations of the IVD in the pelvis. Paired t-test allowed comparisons of: position of the bladder neck; urethral angulation with the pubis axis; position of the urethra; and posterior urethro-vesical angle (PUVA) without and with IVD. At rest, in ten of ten cases IVD laid cranial to the pubo-rectal muscle; with an average angulation of 95 ± 10 with the pubis axis, laterally tilted in three of ten cases. In maximum straining with IVD bladder neck descent was lower by an average of 5.2 ± 3.1 mm (p = 0.001), pubo-urethral angle opening was smaller by an average of 22 ± 20 (p = 0.015), and bladder neck to pubis distance was shorter by an average of 5.7 ± 4 mm. Posterior urethro-vesical angle was not significantly modified. Dynamic MRI allowed a non-invasive assessment of the mode of action of an IVD. The main modifications were a support of the bladder base and bladder neck, with a superior displacement of the urethra toward the pubis. (orig.)

    We compared metronidazole 0.75% gel (containing 37.5 mg metronidazole per dose) with ovules containing metronidazole 500 mg and nystatin 100,000 U, for intravaginal treatment of bacterial vaginosis (BV). In a single-blinded trial, symptomatic women with BV by both Amsel and Nugent criteria were randomly assigned to gel or ovules, once nightly for 5 nights, and asked to return 3 times after treatment. Analyses were intent-to-treat. Of 151 women with BV by both criteria at enrollment, 138 (91%) returned at least once. Product limit estimates for persistence or recurrence of BV at 14, 42, and 104 days were 20% (95% CI 10%-29%), 38% (95% CI 25%-48%), and 52% (95% CI 37%-63%) after gel treatment, and 4% (95% CI 0%-9%), 17% (95% CI 7%-26%), and 33% (95% CI 21%-46%) after ovule treatment ( P = .01). Among women without BV at first follow-up, subsequent intercourse without condoms independently predicted subsequent recurrence ( P Metronidazole/nystatin ovules were significantly more effective than metronidazole gel. Unprotected sex predicted recurrence after initial improvement.

    Hydroxychloroquine (HCQ) has been shown to demonstrate anti-inflammatory properties and direct anti-HIV activity. In this study, we describe for the first time the fabrication and in vitro evaluation of two types of intravaginal ring (IVR) devices (a surfaced-modified matrix IVR and a reservoir segmental IVR) for achieving sustained delivery (>14 days) of HCQ as a strategy for preventing male-to-female transmission of HIV. Both IVRs were fabricated by hot-melt injection molding. Surface-modified matrix IVRs with polyvinylpyrrolidone or poly(vinyl alcohol) coatings exhibited significantly reduced burst release on the first day (6.45% and 15.72% reduction, respectively). Reservoir IVR segments designed to release lower amounts of HCQ displayed near-zero-order release kinetics with an average release rate of 28.38 μg/mL per day for IVRs loaded with aqueous HCQ and 32.23 μg/mL per day for IVRs loaded with HCQ mixed with a rate-controlling excipient. Stability studies demonstrated that HCQ was stable in coated or noncoated IVRs for 30 days. The IVR segments had no significant effect on cell viability, pro-inflammatory cytokine production, or colony formation of vaginal and ectocervical epithelial cells. Both IVR systems may be suitable for the prevention of HIV transmission and other sexually transmitted infections. PMID:25336923

    Premature ejaculation (PE) is the most common male sexual dysfunction. Monosymptomatic enuresis (ME) is nocturnal bed wetting, without any daytime symptoms. Recent clinical studies report an association between lifelong PE and ME. The purpose of this study was to compare the intravaginal ejaculatory time (IELT) between lifelong PE in men with and without ME. The goal was to determine if there is an association between the severity of ME and of IELT. A total of 137 men with lifelong PE were included in this study. Subjects were asked if they had childhood ME. The characteristics and mean IELTs of patients with and without ME were compared using the student's t-test, and the correlation between severity of ME and IELT was assessed with trend test. Of the 137 lifelong PE patients, 57 reported ME. There was a strong negative correlation in patients with ME between the severity of enuresis and IELT, with IELT being shorter in patients with severe ME. A strong correlation between IELT and the severity of ME suggests a common underlying mechanism. Further studies are required to confirm these findings and elucidate the exact pathophysiology.

    Dual segment polyurethane intravaginal rings (IVRs) were fabricated to enable sustained release of antiretroviral agents dapivirine and tenofovir to prevent the male to female sexual transmission of the human immunodeficiency virus. Due to the contrasting hydrophilicity of the two drugs, dapivirine and tenofovir were separately formulated into polymers with matching hydrophilicity via solvent casting and hot melt extrusion. The resultant drug loaded rods were then joined together to form dual segment IVRs. Compression testing of the IVRs revealed that they are mechanically comparable to the widely accepted NuvaRing IVR. Physical characterization of the individual IVR segments using wide angle X-ray scattering and differential scanning calorimetry determined that dapivirine and tenofovir are amorphous and crystalline within their polymeric segments, respectively. In vitro release of tenofovir from the dual segment IVR was sustained over 30 days while dapivirine exhibited linear release over the time period. A 90 day accelerated stability study confirmed that dapivirine and tenofovir are stable in the IVR formulation. Altogether, these results suggest that multisegment polyurethane IVRs are an attractive formulation for the sustained vaginal delivery of drugs with contrasting hydrophilicity such as dapivirine and tenofovir. 2009 Elsevier B.V.

    Vaginal delivery of 200 mg or 25 mg dapivirine from intravaginal rings (IVRs) was evaluated over a 7-day period in two phase 1 safety trials (IPM001 and IPM008, respectively) in a total of 25 healthy women 19 to 46 years of age. The IVR was generally safe and well tolerated with similar adverse events observed in the placebo and dapivirine groups. Across both studies, dapivirine concentrations in vaginal fluids measured at the introitus, cervix, and ring area were within the mean range of 0.7-7.1 microg/ml. Mean dapivirine concentrations in vaginal and cervical tissues on day 7 were 0.3-0.7 microg/g in IPM001 and 1.5-3.5 microg/g in IPM008. Mean plasma concentrations of dapivirine were Dapivirine from both IVRs was successfully distributed throughout the lower genital tract at concentrations >1000x the EC(50) against wild-type HIV-1 (LAI) in MT4 cells suggesting that IVR delivery of microbicides is a viable option meriting further study.

    2011-01-01

    This article analyzes how the Brazilian news media covers the illegal market for misoprostol, the main drug used to induce abortion. A total of 1,429 news stories were retrieved from 220 print and electronic media channels from 2004 to 2009. The analysis included 524 stories from 62 regional and national newspapers. Misoprostol appeared repeatedly in the news, but was usually approached from a criminal perspective, unlike abortion as a whole, which the Brazilian media routinely covers as a religious, political, and public health issue. Misoprostol is part of the illegal gender-related drug market, along with drugs for weight loss and erectile dysfunction and anabolic steroids. Sixty-four (12%) of the news stories told life histories of women who had aborted with misoprostol. The women's ages ranged from 13 to 46 years, and socioeconomic status was associated with different experiences with abortion. Three characters appeared in the women's abortion itineraries: girlfriends (confidantes), go-betweens, and physicians. Stories of late-stage abortion are confused with the criminal characterization of infanticide and provide the extreme cases in the media's narrative on abortion.

    Recent studies demonstrated that intravaginal rings (IVRs) containing 100 mg of the nonnucleoside reverse transcriptase inhibitor (NNRTI) MIV-150 significantly protect macaques against a chimeric simian-human immunodeficiency virus that expresses the HIV-1 HxB2 reverse transcriptase (SHIV-RT) when present before and after vaginal challenge. The objectives of this study were to (i) evaluate the pharmacodynamics (PD) of MIV-150 in vaginal fluids (VF) and in ectocervical and vaginal tissues following 100-mg MIV-150 IVR exposure and to (ii) gain more insight whether pharmacokinetics (PK) of MIV-150 can predict PD. MIV-150 in VF collected at 1 day and 14 days post-MIV-150 IVR insertion inhibited ex vivo SHIV-RT infection in vaginal biopsy specimens from untreated animals (not carrying IVRs) in a dose-dependent manner. Previous PK studies demonstrated a significant increase of ectocervical and vaginal tissue MIV-150 concentrations 14 days versus 1 day post-IVR insertion, with the highest increase in vaginal tissue. Therefore, we tested PD of MIV-150 in tissues 14 days post-MIV-150 IVR insertion. Ex vivo SHIV-RT infection of vaginal, but not ectocervical, tissues collected 14 days post-MIV-150 IVR insertion was significantly inhibited compared to infection at the baseline (prior to MIV-150 IVR exposure). No changes in vaginal and ectocervical tissue infection were observed after placebo IVR exposure. Overall, these data underscore the use of the ex vivo macaque explant challenge models to evaluate tissue and VF PK/PD of candidate microbicides before in vivo animal efficacy studies. The data support further development of MIV-150-containing IVRs.

    The objective of the present study was to investigate if temperature can be utilized to accelerate drug release from Nuvaring®, a reservoir type intravaginal ring based on polyethylene vinyl acetate copolymer that releases a constant dose of contraceptive steroids over a duration of 3 weeks. The reciprocating holder apparatus (USP 7) was utilized to determine real-time and accelerated etonogestrel release from ring segments. It was demonstrated that drug release increased with increasing temperature which can be attributed to enhanced drug diffusion. An Arrhenius relationship of the zero-order release constants was established, indicating that temperature is a valid parameter to accelerate drug release from this dosage form and that the release mechanism is maintained under these accelerated test conditions. Accelerated release tests are particularly useful for routine quality control to assist during batch release of extended release formulations that typically release the active over several weeks, months or even years, since they can increase the product shelf life. The accelerated method should therefore be able to discriminate between formulations with different release characteristics that can result from normal manufacturing variance. In the case of Nuvaring®, it is well known that the process parameters during the extrusion process strongly influence the polymeric structure. These changes in the polymeric structure can affect the permeability which, in turn, is reflected in the release properties. Results from this study indicate that changes in the polymeric structure can lead to a different temperature dependence of the release rate, and as a consequence, the accelerated method can become less sensitive to detect changes in the release properties. When the accelerated method is utilized during batch release, it is therefore important to take this possible restriction into account and to evaluate the accelerated method with samples from non

    TMC 120 (Dapivirine) is a potent non-nucleoside reverse transcriptase inhibitor that is presently being developed as a vaginal HIV microbicide. To date, most vaginal microbicides under clinical investigation have been formulated as single-dose semi-solid gels, designed for application to the vagina before each act of intercourse. However, a clear rationale exists for providing long-term, controlled release of vaginal microbicides in order to afford continuous protection against heterosexually transmitted HIV infection and to improve user compliance. In this study we report on the incorporation of various pharmaceutical excipients into TMC 120 silicone, reservoir-type intravaginal rings (IVRs) in order to modify the controlled release characteristics of the microbicide. The results demonstrate that TMC 120 is released in zero-order fashion from the rings over a 28-day period and that release parameters could be modified by the inclusion of release-modifying excipients in the IVR. The hydrophobic liquid excipient isopropyl myristate had little effect on steady-state daily release rates, but did increase the magnitude and duration of burst release in proportion to excipient loading in the IVR. By comparison, the hydrophobic liquid poly(dimethylsiloxane) had little effect on TMC 120 release parameters. A hydrophilic excipient, lactose, had the surprising effect of decreasing TMC 120 burst release while increasing the apparent steady-state daily release in a concentration-dependent manner. Based on previous cell culture data and vaginal physiology, TMC120 is released from the various ring formulations in amounts potentially capable of maintaining a protective vaginal concentration. It is further predicted that the observed release rates may be maintained for at least a period of 1 year from a single ring device. TMC 120 release profiles and the mechanical properties of rings could be modified by the physicochemical nature of hydrophobic and hydrophilic excipients

    Women urgently need a self-initiated, multipurpose prevention technology (MPT) that simultaneously reduces their risk of acquiring HIV-1, HSV-2, and HPV (latter two associated with increased risk of HIV-1 acquisition) and prevents unintended pregnancy. Here, we describe a novel core-matrix intravaginal ring (IVR), the MZCL IVR, which effectively delivered the MZC combination microbicide and a contraceptive. The MZCL IVR contains four active pharmaceutical ingredients (APIs): MIV-150 (targets HIV-1), zinc acetate (ZA; targets HIV-1 and HSV-2), carrageenan (CG; targets HPV and HSV-2), and levonorgestrel (LNG; targets unintended pregnancy). The elastomeric IVR body (matrix) was produced by hot melt extrusion of the non-water swellable elastomer, ethylene vinyl acetate (EVA-28), containing the hydrophobic small molecules, MIV-150 and LNG. The solid hydrophilic core, embedded within the IVR by compression, contained the small molecule ZA and the macromolecule CG. Hydrated ZA/CG from the core was released by diffusion via a pore on the IVR while the MIV-150/LNG diffused from the matrix continuously for 94 days (d) in vitro and up to 28 d (study period) in macaques. The APIs released in vitro and in vivo were active against HIV-1ADA-M, HSV-2, and HPV16 PsV in cell-based assays. Serum LNG was at levels associated with local contraceptive effects. The results demonstrate proof-of-concept of a novel core-matrix IVR for sustained and simultaneous delivery of diverse molecules for the prevention of HIV, HSV-2 and HPV acquisition, as well as unintended pregnancy.

    Dendrimers are emerging as promising topical antimicrobial agents, and as targeted nanoscale drug delivery vehicles. Topical intravaginal antimicrobial agents are prescribed to treat the ascending genital infections in pregnant women. The fetal membranes separate the extra-amniotic space and fetus. The purpose of the study is to determine if the dendrimers can be selectively used for local intravaginal application to pregnant women without crossing the membranes into the fetus. In the present study, the transport and permeability of PAMAM (poly (amidoamine)) dendrimers, across human fetal membrane (using a side by side diffusion chamber), and its biodistribution (using immunofluorescence) are evaluated ex-vivo. Transport across human fetal membranes (from the maternal side) was evaluated using Fluorescein (FITC), an established transplacental marker (positive control, size approximately 400 Da) and fluorophore-tagged G(4)-PAMAM dendrimers (approximately 16 kDa). The fluorophore-tagged G(4)-PAMAM dendrimers were synthesized and characterized using (1)H NMR, MALDI TOF MS and HPLC analysis. Transfer was measured across the intact fetal membrane (chorioamnion), and the separated chorion and amnion layers. Over a 5 h period, the dendrimer transport across all the three membranes was less than dendrimer (5.8 x 10(-8) cm(2)/s). The biodistribution showed that the dendrimers were largely present in interstitial spaces in the decidual stromal cells and the chorionic trophoblast cells (in 2.5-4 h) and surprisingly, to a smaller extent internalized in nuclei of trophoblast cells and nuclei and cytoplasm of stromal cells. Passive diffusion and paracellular transport appear to be the major route for dendrimer transport. The overall findings further suggest that entry of drugs conjugated to dendrimers would be restricted across the human fetal membranes when administered topically by intravaginal route, suggesting new ways of selectively delivering therapeutics to the mother

Twenty-four Dorper and crossbred ewes were allocated into three groups and received intravaginal implant containing 0.3g progesterone (CIDR(r, 60mg MAP or sponges without progesterone (CONTROL for six days. Then, CIDR and MAP treated-ewes received 12.5mg dinoprost and 300IU eCG. Vaginal mucus samples were collected at four times: before device insertion, at the day of its removal, 24 and 48 hours after. The samples were cultured and the colonies were counted (CFU/mL and identified. The results obtained from the counting of CFU mL-1 were submitted to Kruskal-Wallis H test, with P0.05 in comparison with MAP and CIDR-treated ewes. During the occurrence of vaginitis, the predominant isolates belonged to the coliform group, mainly Escherichia coli (72.7%. Such infection was not determined by the members of the vaginal microbiota that were present before implant insertion and normal microbiota was restored between 24 to 48 hours after insert removal.

    Access to injectable uterotonics for management of postpartum haemorrhage remains limited in Senegal outside health facilities, and misoprostol and oxytocin delivered via Uniject have been deemed viable alternatives in community settings. We aimed to compare the efficacy of these drugs when delivered by auxiliary midwives at maternity huts. We did an unmasked cluster-randomised controlled trial at maternity huts in three districts in Senegal. Maternity huts with auxiliary midwives located 3-21 km from the closest referral centre were randomly assigned (1:1; via a computer-generated random allocation overseen by Gynuity Health Projects) to either 600 μg oral misoprostol or 10 IU oxytocin in Uniject (intramuscular), stratified by reported previous year clinic volume (deliveries) and geographical location (inland or coastal). Maternity huts that had been included in a previous study of misoprostol for prevention of postpartum haemorrhage were excluded to prevent contamination. Pregnant women in their third trimester were screened for eligibility either during community outreach or at home-based prenatal visits. Only women delivered by the auxiliary midwives in the maternity huts were eligible for the study. Women with known allergies to prostaglandins or pregnancy complications were excluded. The primary outcome was mean change in haemoglobin concentration measured during the third trimester and after delivery. This study was registered with ClinicalTrials.gov, number NCT01713153. 28 maternity hut clusters were randomly assigned-14 to the misoprostol group and 14 to the oxytocin group. Between June 6, 2012, and Sept 21, 2013, 1820 women were recruited. 647 women in the misoprostol group and 402 in the oxytocin group received study drug and had recorded pre-delivery and post-delivery haemoglobin concentrations, and overall 1412 women delivered in the study maternity huts. The mean change in haemoglobin concentrations was 3·5 g/L (SD 16·1) in the misoprostol group

    There are uncertain issues on the diagnostic methods of premature ejaculation (PE). The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria in diagnosing PE and the aim of this study is to carry out the Turkish validation of the PEDT and to evaluate its association with intravaginal ejaculatory latency time (IELT). A total of 94 patients with a self-reported complaint of PE and 88 men without PE were enrolled into the study and requested to complete the nine-item PEDT, which was translated into Turkish. The patients were also requested to measure IELT. All participants were requested to come for a second visit to assess the PEDT's retest reliability; data from 78 men in the PE group and 69 men in the control group were collected. The IELT data of 35 patients were also recorded. The mean age of the PE group and the control group were 39.4+/-9.7 (24-65) and 30.1+/-5.7 (20-56), respectively, (P=0.068). Among the patients in the PE group, 24 (68.5%) reported life-long PE, whereas 11 (31.5%) reported acquired PE. The geometric mean IELT of the PE group was 59.7+/-46.2 (6.5-197.7) s. The number of men reporting IELTs of 2 min were 20 (57.1%), 11 (31.5) and 4 (11.4%), respectively. The factor analysis assessment showed that the five-item combination (questions 1, 2, 3, 4 and 8) explained 74.4% of the variance, there were no other combinations that explained the variance more effectively. Cronbach's alpha score of five-item combination was calculated as 0.77, showing adequate internal consistency. The overall Cronbach's alpha score did not increase if any item combination was deleted. The test-retest correlation coefficients of each item were higher than 0.80 and the correlation coefficient of the total score was 0.90. The PEDT and IELT showed an adequate correlation (rho=0.44). As a conclusion, the validated five-item Turkish version of PEDT is a

    A radioimmunoassay (RIA) method for measuring d-Norgestrel (d-Ng) in serum has been developed utilizing petroleum ether extraction, an antiserum raised against d-Norgestrel-3-(0-carboxymethyl) oxime-epsilon-aminocaproic acid--boxine serum albumin, d-Norgestrel-3-(0-carboxymethyl) imino-[ 125 I]-iodohistamine, and dextran-coated charcoal separation. Control serum blanks were undetectable, 6 pg of d-Ng was measurable in 0.1 ml of serum with a high reliability, and intra- and interassay coefficients of variation were 4.4 and 4.9 percent, respectively. d-Ng added to control serum was quantitatively recovered. This RIA proved to be highly specific for d-Ng, cross-reacting less than 0.01 percent with 1-Ng and some 4 to 8 percent with 5α- and 5β-tetrahydro-d-Ng. Serum d-Ng levels measured in 3 women after ingestion of 75 μg of dl-Ng rose to 1.5 to 2 ng/ml within 1/2 to 2-3 hours after oral intake and fell rapidly thereafter to 0.2 to 0.4 ng/ml within 24 hours. Insertion of Silastic intravaginal rings (IVRs), containing 50 or 100 mg of dl-Ng, into 3 women for periods of 3 weeks resulted in a rapid rise of serum d-Ng after insertion. Serum d-Ng levels were highest 24 to 48 hours after the first insertion of each IVR, reaching peak levels of about 5 and 7 to 11 ng/ml, respectively, and declined gradually during the ensuing 15 to 20 days to some 30 to 40 percent of the peak serum d-Ng concentration. Serum d-Ng levels attained after IVR reinsertion remained relatively constant at 1 to 3 ng/ml during each subsequent cycle in all subjects and fell rapidly after each IVR removal. Serum estradiol and progesterone concentrations, measured about 3 times a week in these patients, indicated that ovulation was consistently inhibited

    Full Text Available Andrea Ries Thurman, Meredith R Clark, Jennifer Hurlburt, Gustavo F Doncel CONRAD, Department of Obstetrics and Gynecology, Eastern Virginia Medical School, Norfolk, VA, USA Abstract: There is a renewed interest in delivering pharmaceutical products via intravaginal rings (IVRs. IVRs are flexible torus-shaped drug delivery systems that can be easily inserted and removed by the woman and that provide both sustained and controlled drug release, lasting for several weeks to several months. In terms of women's health care products, it has been established that IVRs effectively deliver contraceptive steroids and steroids for the treatment of postmenopausal vaginal atrophy. A novel application for IVRs is the delivery of antiretroviral drugs for the prevention of human immunodeficiency virus (HIV genital infection. Microbicides are antiviral drugs delivered topically for HIV prevention. Recent reviews of microbicide IVRs have focused on technologies in development and optimizing ring design. IVRs have several advantages, including the ability to deliver sustained drug doses for long periods of time while bypassing first pass metabolism in the gut. IVRs are discreet, woman-controlled, and do not require a trained provider for placement or fitting. Previous data support that women and their male sexual partners find IVRs highly acceptable. Multipurpose prevention technology (MPT products provide protection against unintended/mistimed pregnancy and reproductive tract infections, including HIV. Several MPT IVRs are currently in development. Early clinical testing of new microbicide and MPT IVRs will require a focus on safety, pharmacokinetics and pharmacodynamics. Specifically, IVRs will have to deliver tissue concentrations of drugs that are pharmacodynamically active, do not cause mucosal alterations or inflammation, and do not change the resident microbiota. The emergence of resistance to antiretrovirals will need to be investigated. IVRs should not

    In Peru, abortion is legal only to preserve the life and health of the woman. A non-profit clinic system in Peru implemented a harm-reduction model for women with unwanted pregnancy that included pre-abortion care with instructions about misoprostol use and post-abortion care; they started offering telephone follow-up for clients in 2011. This study aimed to evaluate the effectiveness and safety of the harm-reduction model, and to compare outcomes by type of follow-up obtained. Between January 2012 and March 2013, 500 adult women seeking harm-reduction services were recruited into the study. Telephone surveys were conducted approximately four weeks after their initial harm-reduction counseling session with 262 women (response rate 52%); 9 participants were excluded. The survey focused on whether women pursued an abortion, and if so, what their experience was. Demographic and clinical data were also extracted from clinic records. Eighty-six percent of participants took misoprostol; among those taking misoprostol, 89% reported a complete abortion at the time of the survey. Twenty-two percent obtained an aspiration after taking misoprostol and 8% self-reported adverse events including hemorrhage without transfusion, infection, or severe pain. Among women who took misoprostol, 46% reported receiving in-person follow-up (in some cases both telephone and in-person), 34% received telephone only, and 20% did not report receiving any form of follow-up. Those who had in-person follow-up with the counselor were most likely to report a complete abortion (<0.001). Satisfaction with both types of follow-up was very high, with 81%-89% reporting being very satisfied. Liberalization of restrictive abortion laws is associated with improvements in health outcomes, but the process of legal reform is often lengthy. In the interim, giving women information about evidence-based regimens of misoprostol, as well as offering a range of follow-up options to ensure high quality post

Low-dose mifepristone and misoprostol administered at the time of expected menstruation was effective and safe in maintaining or restoring non-pregnant status, with no obvious menstrual disturbance. Menstrual regulation involves the medical or mechanical stimulation of uterine sloughing in women with up to 2-3 weeks of menstrual delay. Low-dose mifepristone plus misoprostol is efficacious for termination of ultra-early pregnancy (≤ 35 days of amenorrhoea) with no obvious menstrual disturbance. A total of 678 women fulfilled all criteria and were recruited. Seventeen women dropped out after deciding to remain pregnant and 11 others were lost to follow-up. Thus, data from 650 women who completed the procedure were included in analyses. Participants were enrolled at any time during their menstrual cycle and administered medication 1 day before expected menstruation. The end of the study was defined on a per-patient basis as the date of completion of the post-treatment menstrual cycle. The primary outcome was the efficacy of abortion induction (for pregnant women) or menstrual regulation (for non-pregnant women). Women with regular menstrual cycles (25-35 days) were voluntarily recruited for this study between February 2012 and December 2014. Serum β-hCG was measured before mifepristone intake. Mifepristone (50 mg) was administered orally 1 day before expected menstruation and 200 µg misoprostol was administered orally on the day of expected menstruation. Efficacy, disturbance in bleeding patterns in the treatment and post-treatment cycles, satisfaction with the treatment, and subsequent contraception preference were analysed. Retrospective analysis of serum β-hCG levels at admission indicated that 23.3% (158/678) of the women were pregnant. The success rate for pregnancy termination was 98.6% (136

    To compare the effects of misoprostol versus ergometrine-oxytocin for postpartum haemorrhage (PPH) prevention, and provide important evidence to choose optimal agents for preventing PPH in developing countries. The Cochrane Central Register of Controlled Trials, PubMed, EMbase, and ClinicalTrails.gov were searched from inception to 1st January 2016. Two authors independently extracted data and assessed risk of bias of studies according to Cochrane Handbook5.1.0. Meta-analysis was performed using RevMan5.2.4 software. A total of 4034 women from six randomized controlled trials (RCTs) were included. Meta-analyses showed that the PPH rate (7.6% vs. 4.2%, RR = 1.81, 95%CI (1.40, 2.35), P oxytocin group, respectively. But there was no significant difference of severe PPH rate between two groups (1.2% vs. 0.76%, RR = 1.55, 95%CI (0.78, 3.07), P = 0.21). The need for manual removal of placenta in misoprostol was only about one-third of ergometrine-oxytocin (0.5% vs. 1.4%, RR = 0.33, 95%CI (0.15, 0.76), P oxytocin could be deemed as alternative agent in low-resource setting due to recognized effect. As a result of limited evidence about these uterotonic agents, the more high-quality RCTs are needed to determine the potentials and harms of various uterotonic agents for preventing PPH in developing countries. © 2016 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

    Our objectives were to evaluate circulating progesterone (P4) concentration dynamics and test the feasibility of inducing luteal regression after intravaginal (IVG) instillation of the PGF2α analogue dinoprost (PGF) in lactating dairy cows. In two experiments, cows were synchronized using the Ovsynch protocol to induce the formation of a corpus luteum (CL). Cows with at least one functional (P4 ≥1 ng/mL) CL ≥15 mm 7.5 days after Ovsynch remained in the studies. In experiment 1, cows (n = 31) were stratified by parity group and received 5 mL of saline IVG (SAL-IVG, n = 6), 25 mg of PGF intramuscular (IM) (PGF25-IM, n = 7), 25 mg of PGF IVG (PGF25-IVG, n = 6), 50 mg of PGF IVG (PGF50-IVG, n = 6), and 125 mg of PGF IVG (PGF125-IVG, n = 6). Experiment 2 was conducted to test the hypothesis that IVG instillation of two 25 mg doses of PGF 12 hours apart would be more effective than a 25- or 50-mg dose in a single application. Cows (n = 32) were stratified by parity and received SAL-IVG (n = 7), PGF25-IM (n = 7), PGF25-IVG (n = 6), and PGF50-IVG (n = 6) as in experiment 1, whereas another group received two IVG instillations of 25 mg of PGF 12 hours apart (PGF25-2X-IVG, n = 6). Blood was collected at -1 hour, every 6 hours from 0 hour to 24 hours, and every 12 hours up to 96 hours after treatment (trt). In experiment 1, there was an effect of trt (P cows in the SAL-IVG group from 12 to 96 hours after trt. Although an initial decline in P4 concentrations was induced in all PGF-treated cows, some cows in the IVG-treated groups presented a rebound in plasma P4, indicating CL recovery. More cows in the PGF25-IVG and PGF125-IVG groups than in the PGF50-IVG and PGF25-IM groups presented CL recovery, suggesting that greater doses of PGF may not necessarily improve CL regression. In experiment 2, there was an effect of trt (P Cows in the PGF25-2X-IVG group had a P4 profile that was similar to that of cows in the PGF25-IM group and

  15. If we can do it for misoprostol, why not for mifepristone? The case for taking mifepristone out of the office in medical abortion.

    2015-09-01

    Given the highly political nature of abortion in the United States, the provision of medical abortion with mifepristone (Mifeprex®) and misoprostol has always occurred under a unique set of circumstances. The Food and Drug Administration-approved regimen requires clinicians to administer the mifepristone in the office and also requires women to return to the office for the misoprostol. In the US, where off-label drug use is an accepted practice when supportive evidence exists, most clinicians give women the misoprostol at the initial visit for her to take at home, eliminating an unnecessary visit to the office. This commentary suggests that, based on current studies, there is also enough evidence to offer women the option to self-administer mifepristone out of the office and that this is just another feature of off-label use. Six studies, enrolling over 1800 women, found that the option of taking mifepristone out of the office was popular and acceptable among women and providers. Given that it is safe, highly acceptable and not burdensome on providers, outside-office-use of mifepristone should be offered to all women as part of routine medical abortion services.

    To evaluate the efficacy of a combined protocol of mifepristone and misoprostol in the management of early pregnancy failure (EPF) and the average time to expulsion of tissue and rate of side effects. Retrospective chart review of all consecutive women treated with primary medical management for EPF at our institution from 2006 to 2012. 168 patients were included in the present study. The overall success rate, defined as the absence of the need for surgical intervention, was 61 % and did not differ by calendar year. There was no difference in success rate grouped by diagnosis [intrauterine embryonic/fetal demise (IUED/IUFD) vs. anembryonic gestation; p = 0.30] or gestational age (800 μg (68 vs. 50 %, p = 0.029). Of the possible predictive factors of success, only the dose of misoprostol required was a significant independent negative predictor. Mean and median time to tissue expulsion after the first dose of misoprostol were 8.4 and 5.5 h, respectively. The incidence of side effects was low with no blood transfusions required. The success rate in this study is markedly below published data. This can possibly be attributed to retrospective study design, allowing for physician subjectivity and patients' wishes in the absence of strict study requirements. The protocol was well tolerated with a paucity of side effects. We make suggestions for enhancing success rates in the clinical setting by optimizing medication protocols, establishing precise treatment guidelines and training physicians in the accurate interpretation of treatment outcomes.

  17. Engineering a segmented dual-reservoir polyurethane intravaginal ring for simultaneous prevention of HIV transmission and unwanted pregnancy.

    Full Text Available The HIV/AIDS pandemic and its impact on women prompt the investigation of prevention strategies to interrupt sexual transmission of HIV. Long-acting drug delivery systems that simultaneously protect womenfrom sexual transmission of HIV and unwanted pregnancy could be important tools in combating the pandemic. We describe the design, in silico, in vitro and in vivo evaluation of a dual-reservoir intravaginal ring that delivers the HIV-1 reverse transcriptase inhibitor tenofovir and the contraceptive levonorgestrel for 90 days. Two polyether urethanes with two different hard segment volume fractions were used to make coaxial extruded reservoir segments with a 100 µm thick rate controlling membrane and a diameter of 5.5 mm that contain 1.3 wt% levonorgestrel. A new mechanistic diffusion model accurately described the levonorgestrel burst release in early time points and pseudo-steady state behavior at later time points. As previously described, tenofovir was formulated as a glycerol paste and filled into a hydrophilic polyurethane, hollow tube reservoir that was melt-sealed by induction welding. These tenofovir-eluting segments and 2 cm long coaxially extruded levonorgestrel eluting segments were joined by induction welding to form rings that released an average of 7.5 mg tenofovir and 21 µg levonorgestrel per day in vitro for 90 days. Levonorgestrel segments placed intravaginally in rabbits resulted in sustained, dose-dependent levels of levonorgestrel in plasma and cervical tissue for 90 days. Polyurethane caps placed between segments successfully prevented diffusion of levonorgestrel into the tenofovir-releasing segment during storage.Hydrated rings endured between 152 N and 354 N tensile load before failure during uniaxial extension testing. In summary, this system represents a significant advance in vaginal drug delivery technology, and is the first in a new class of long-acting multipurpose prevention drug delivery systems.

    Full Text Available Medroxyprogesterone acetate is widely used in veterinary medicine as intravaginal dosage for the synchronization of breeding cycle in ewes and goats. The main goal of this study was to develop reverse-phase high-performance liquid chromatography method for the quantification of medroxyprogesterone acetate in veterinary vaginal sponges. A single high-performance liquid chromatography/UV isocratic run was used for the analytical assay of the active ingredient medroxyprogesterone. The chromatographic system consisted of a reverse-phase C18 column as the stationary phase and a mixture of 60% acetonitrile and 40% potassium dihydrogen phosphate buffer as the mobile phase; the pH was adjusted to 5.6. The method was validated according to the International Council for Harmonisation (ICH guidelines. Forced degradation studies were also performed to evaluate the stability-indicating properties and specificity of the method. Medroxyprogesterone was eluted at 5.9 minutes. The linearity of the method was confirmed in the range of 0.0576 to 0.1134 mg/mL ( R 2 > 0.999. The limit of quantification was shown to be 3.9 µg/mL. Precision and accuracy ranges were found to be %RSD <0.2 and 98% to 102%, respectively. Medroxyprogesterone capacity factor value of 2.1, tailing factor value of 1.03, and resolution value of 3.9 were obtained in accordance with ICH guidelines. Based on the obtained results, a rapid, precise, accurate, sensitive, and cost-effective analysis procedure was proposed for quantitative determination of medroxyprogesterone in vaginal sponges. This analytical method is the only available method to analyse medroxyprogesterone in veterinary intravaginal dosage form.

    Synthetic meshes have been used extensively to augment surgical management of pelvic organ prolapses. Posterior intravaginal sling (IVS) is a technique used for correcting vaginal vault/apical prolapse, posterior vaginal prolapse or rectocele. There are limited data on long-term safety of this procedure. In a subanalysis of the IVS tapes from the SUSPEND trial performed secondary to the large number of patients with complications of suburethral sling erosions after IVS, it was noted that the sling erosion tended to have a delayed presentation secondary to poor incorporation of the mesh. A 48-year-old woman with cystocele, uterine prolapse and rectocele had undergone total vaginal hysterectomy, mesh-augmented anterior repair, posterior colporrhaphy and posterior intravaginal slingplasty (IVS) in July 2005. Thirty months after the surgery, she presented with gradual symptoms of copious vaginal discharge for several weeks followed by constant right buttock pain and swelling. Examination was notable for intact mesh with no signs of erosion and a 3-cm induration deep within the right buttock. Computed tomography suggested a pelvic abscess. Magnetic resonance imaging confirmed a right ischiorectal fossa abscess and a vaginal fistula. The patient underwent sling excision, right ischiorectal fossa exploration and vaginal fistula repair. A fistulous tract was found to extend along the intact sling from the vaginal epithelium toward the right ischiorectal fossa. At 2 months' followup, there were no recurrences or other complications. This is the first report of a delayed complication of an ischiorectal abscess associated with an ischiorectal-vaginal fistula that presented 30 months after the placement of a posterior IVS.

    Oral misoprostol, administered by trained health-workers is effective and safe for preventing postpartum haemorrhage (PPH). There is interest in expanding administration of misoprostol by non-health workers, including task-shifting to pregnant women themselves. However, the use of misoprostol for preventing PPH in home-births remains controversial, due to the limited evidence to support self-administration or leaving it in the hands of non-health workers. This study aimed to determine if antenatally distributing misoprostol to pregnant women to self-administer at home birth reduces PPH. Between February 2013 and March 2014, we conducted a stepped-wedge cluster-randomized trial in six health facilities in Central Uganda. Women at 28+ weeks of gestation attending antenatal care were eligible. Women in the control-arm received the standard-of-care; while the intervention-arm were offered 600 mcg of misoprostol to swallow immediately after birth of baby, when oxytocin was not available. The primary outcome (PPH) was a drop in postpartum maternal haemoglobin (Hb) by ≥ 2 g/dl, lower than the prenatal Hb. Analysis was by intention-to-treat at the cluster level and we used a paired t-tests to assess whether the mean difference between the control and intervention groups was statistically significant. 97% (2466/2545) of eligible women consented to participate; 1430 and 1036 in the control and intervention arms respectively. Two thousand fifty-seven of the participants were successfully followed up and 271 (13.2%) delivered outside a health facility. There was no significant difference between the study group in number of women who received a uterotonic at birth (control 80.4% vs intervention 91.4%, mean difference = -11.0%, 95% confidence interval [CI] -25.7% to 3.6%, p = 0.11). No woman took misoprostol before their baby's birth. Shivering and fever were 14.9% in the control arm compared to 22.2% in the intervention arm (mean difference = -7.2%, 95% CI -11.1% to -3

    Full Text Available The objective of this investigation was to evaluate whether intravaginal infusion of a lactic acid bacteria (LAB cocktail around parturition could influence the immune response, incidence rate of uterine infections, and the overall health status of periparturient dairy cows. One hundred pregnant Holstein dairy cows were assigned to 1 of the 3 experimental groups as follows: 1 one dose of LAB on wk -2 and -1, and one dose of carrier (sterile skim milk on wk +1 relative to the expected day of parturition (TRT1; 2 one dose of LAB on wk -2, -1, and +1 (TRT2, and 3 one dose of carrier on wk -2, -1, and +1 (CTR. The LAB were a lyophilized culture mixture composed of Lactobacillus sakei FUA3089, Pediococcus acidilactici FUA3138, and Pediococcus acidilactici FUA3140 with a cell count of 108-109 cfu/dose. Blood samples and vaginal mucus were collected once a week from wk -2 to +3 and analyzed for content of serum total immunoglobulin G (IgG, lipopolysaccharide-binding protein (LBP, serum amyloid A (SAA, haptoglobin (Hp, tumor necrosis factor (TNF, interleukin (IL-1, IL-6, and vaginal mucus secretory IgA (sIgA. Clinical observations including rectal temperature, vaginal discharges, retained placenta, displaced abomasum, and laminitis were monitored from wk -2 to +8 relative to calving. Results showed that intravaginal LAB lowered the incidence of metritis and total uterine infections. Intravaginal LAB also were associated with lower concentrations of systemic LBP, an overall tendency for lower SAA, and greater vaginal mucus sIgA. No differences were observed for serum concentrations of Hp, TNF, IL-1, IL-6 and total IgG among the treatment groups. Administration with LAB had no effect on the incidence rates of other transition cow diseases. Overall intravaginal LAB lowered uterine infections and improved local and systemic immune responses in the treated transition dairy cows.

    Full Text Available Intravaginal anti-HIV microbicides could provide women with a self-controlled means for HIV prevention, but results from clinical trials have been largely disappointing. We postulated that unrecognized effects of intravaginal gels on the upper female reproductive tract might contribute to the lower-than-expected efficacy of HIV microbicides. Our objective was to study the effects of intravaginal gels on the immune microenvironment of the cervix and uterus. In this randomized crossover study, 27 healthy female volunteers used a nightly application of intravaginal nonoxynol-9 (N9 gel as a "failed" microbicide or the universal placebo gel (UPG as a "safe" gel (intervention cycles, or nothing (control cycle from the end of menses to the mid-luteal phase. At a specific time-point following ovulation, all participants underwent sample collection for measurements of T-cell phenotypes, gene expression, and cytokine/chemokine protein concentrations from 3 anatomic sites above the vagina: the cervical transformation zone, the endocervix and the endometrium. We used hierarchical statistical models to estimate mean (95% CI intervention effects, for N9 and UPG relative to control. Exposure to N9 gel and UPG generated a common "harm signal" that included transcriptional up-regulation of inflammatory genes chemokine (C-C motif ligand 20 (macrophage inflammatory factor-3alpha and interleukin 8 in the cervix, decreased protein concentrations of secretory leukocyte protease inhibitor, and transcriptional up-regulation of inflammatory mediators glycodelin-A and osteopontin in the endometrium. These results need to be replicated with a larger sample, but underscore the need to consider the effects of microbicide agents and gel excipients on the upper female reproductive tract in studies of vaginal microbicides.

    Vaginal microbicides for the prevention of HIV transmission may be an important option for protecting women from infection. Incorporation of dapivirine, a lead candidate nonnucleoside reverse transcriptase inhibitor, into intravaginal rings (IVRs) for sustained mucosal delivery may increase microbicide product adherence and efficacy compared with conventional vaginal formulations. Twenty-four healthy HIV-negative women 18-35 years of age were randomly assigned (1:1:1) to dapivirine matrix IVR, dapivirine reservoir IVR, or placebo IVR. Dapivirine concentrations were measured in plasma and vaginal fluid samples collected at sequential time points over the 33-day study period (28 days of IVR use, 5 days of follow-up). Safety was assessed by pelvic/colposcopic examinations, clinical laboratory tests, and adverse events. Both IVR types were safe and well tolerated with similar adverse events observed in the placebo and dapivirine groups. Dapivirine from both IVR types was successfully distributed throughout the lower genital tract at concentrations over 4 logs greater than the EC50 against wild-type HIV-1 (LAI) in MT4 cells. Maximum concentration (Cmax) and area under the concentration-time curve (AUC) values were significantly higher with the matrix than reservoir IVR. Mean plasma concentrations of dapivirine were <2 ng/mL. These findings suggest that IVR delivery of microbicides is a viable option meriting further study.

    The past decade has seen several effective anti-HIV-1 agent discoveries, yet microbicides continue to disappoint clinically. Our review expounds the view that unsatisfactory microbicide failures may be a result of inefficient delivery systems employed. We hereby propose a thorough scientific qualitative and quantitative investigation of important aspects involved in HIV-1 transmission as a prerequisite for microbicide delivery. Intravaginal targeting of HIV-1 increases the chances of microbicide success, wherein vaginal microenvironmental factors including pH should be maintained at HIV-1 prohibitive acidic levels simultaneously to ward off other sexually transmitted diseases, which compromise vaginal epithelial barrier properties. Furthermore, choice of receptors to target both on HIV-1 and on target cells is vital in deterring transmission. Appropriate modeling of virus-target cell interactions as well as targeting early stages of the HIV-1 infection accompanied by computation and delivery of appropriate microbicide quantities could revolutionize microbicide research, ultimately delivering a female-controlled HIV-1 prevention modality appropriately.

    Purpose: The oral complications associated with radiotherapy to the head and neck are a significant dose-limiting factor. The goals of this study were to determine whether oropharyngeal rinsing and ingestion of misoprostol protect mucous membranes from the acute effects of irradiation, and to evaluate the quality-of-life (QOL) outcomes of patients receiving misoprostol. We report the results of the QOL outcomes of patients in this study. Methods and Materials: A total of 33 patients with resected or intact cancer of the oral cavity, oropharynx, supraglottic larynx, or hypopharynx were registered to receive postoperative radiotherapy plus misoprostol or primary radiotherapy plus misoprostol. All patients were scheduled to receive 60-70 Gy at 2 Gy/d within 6-7 weeks. QOL and function were evaluated. Results: A decrease in the QOL and function occurred in all areas covered by the questionnaire at the 6-week interval. This decrease was significant for eating, saliva, taste, and mucous. Of these significant factors, taste, saliva, and mucous consistency had not resolved by 12 weeks. Conclusion: Increased understanding of the impact of treatment on QOL and symptoms will formulate the rational design of toxicity interventions and enhance the multidisciplinary care of head-and-neck patients

    Effective treatment of chronic myelogenous leukemia (CML) largely depends on the eradication of CML leukemic stem cells (LSCs). We recently showed that CML LSCs depend on Tcf1 and Lef1 factors for self-renewal. Using a connectivity map, we identified prostaglandin E1 (PGE1) as a small molecule that partly elicited the gene expression changes in LSCs caused by Tcf1/Lef1 deficiency. Although it has little impact on normal hematopoiesis, we found that PGE1 treatment impaired the persistence and activity of LSCs in a pre-clinical murine CML model and a xenograft model of transplanted CML patient CD34 + stem/progenitor cells. Mechanistically, PGE1 acted on the EP4 receptor and repressed Fosb and Fos AP-1 factors in a β-catenin-independent manner. Misoprostol, an FDA-approved EP4 agonist, conferred similar protection against CML. These findings suggest that activation of this PGE1-EP4 pathway specifically targets CML LSCs and that the combination of PGE1/misoprostol with conventional tyrosine-kinase inhibitors could provide effective therapy for CML.

    Mismatch of partners in premature ejaculation (PE) regarding intra-vaginal ejaculation latency time (IELT) is usually neglected. Here we proposed the concept and evaluated the use of index of IELT (IIELT) as an objective diagnostic tool for PE. Data from 103 self-reporting PE patients and 59 normal controls were collected. The expected IELTs of both the male and female partners were provided by each participating couple in two questionnaires. IIELT=stopwatch IELT/(1/2 the male's expected IELT+1/2 the female's expected IELT). The stopwatch IELTs were 1.74±1.4 min (PE group) and 14.45±11.0 min (control group), PIELTs were 15.65±8.7 min (men) and 14.16±6.9 min (women) in the PE group, and 21.3±16.1 min (men) and 20.04±13.47 min (women) in the control group, P<0.05. The calculated IIELTs were 0.14±0.12 (PE group) and 0.83±0.60 (control group), P<0.05. The best cut-off point was 0.658, the Youden index was 0.652, sensitivity was 0.991, specificity was 0.661, positive predictive probability was 83.46% and negative predictive probability was 97.6%. We concluded that IIELT was an integrated measurement of the couples' sexual equilibrium and demonstrated that it provided a simple and objective screening indicator for diagnosing self-reported PE.

    Premature ejaculation (PE) is the most prevalent male ejaculation disorder. The premature ejaculation diagnostic tool (PEDT) was developed to systematically apply the DSM-IV-TR criteria in diagnostic PE. To evaluate the diagnostic value of the PEDT and its association with intravaginal ejaculatory latency time (IELT). (i) Korean validation of PEDT: data was collected from men interviewed by one of the two clinical experts, who made a diagnostic of present or absence of PE, using DSM-IV-TR criteria. A total of 103 patients with PE and 100 men without PE were enrolled into the study and requested to complete the PEDT; and (ii) The correlation between IELT and PEDT: 200 participants were enrolled and each participant was asked to make out PEDT. All participants were requested to measure IELT. Validity and reliability of the PEDT and its association with IELT. The geometric mean IELT of the PE group was 115.37 ± 78.14 seconds. The number of men reporting IELTs of 2 minutes were 28 (28.6%), 29 (29.6%), and 41 (41.8%), respectively. The Cronbach's alpha score was calculated as 0.93, showing adequate internal consistency. The test-retest correlation coefficients of each item were higher than 0.72 and the correlation coefficients of the total score was 0.88. (P IELT showed an adequate negative correlation. (ρ = -0.77, P IELT ≤ 2 minutes) and IELT showed a negative correlation. (ρ = -0.6, P < 0.0001) The PEDT was highly effective in detecting the presence of PE. The result of our study supports its validity as a diagnostic tool in the clinical setting. © 2010 International Society for Sexual Medicine.

    Full Text Available Abstract Background The objective of this study was to compare intravaginal (ivg and subcutaneous (sc administration of the guinea pig cytomegalovirus (GPCMV in pregnant and non-pregnant guinea pigs. These studies tested the hypotheses that ivg infection would elicit immune responses, produce maternal viremia, and lead to vertical transmission, with an efficiency similar to the traditionally employed sc route. Results Four groups of age- and size-matched guinea pigs were studied. Two groups were pregnant, and two groups were not pregnant. Animals received 5x105 plaque-forming units (PFU of a GPCMV reconstituted from an infectious bacterial artificial chromosome (BAC construct containing the full-length GPCMV genome. Seroconversion was compared by IgG ELISA, and viremia (DNAemia was monitored by PCR. In both pregnant and non-pregnant animals, sc inoculation resulted in significantly higher serum ELISA titers than ivg inoculation at 8 and 12 weeks post-infection. Patterns of viremia (DNAemia were similar in animals inoculated by either sc or ivg route. However, in pregnant guinea pigs, animals inoculated by both routes experienced an earlier onset of DNAemia than did non-pregnant animals. Neither the percentage of dead pups nor the percentage of GPCMV positive placentas differed by inoculation route. Conclusions In the guinea pig model of congenital CMV infection, the ivg route is as efficient at causing congenital infection as the conventional but non-physiologic sc route. This finding could facilitate future experimental evaluation of vaccines and antiviral interventions in this highly relevant animal model.

    Long-acting GSK1265744 (GSK744 LA) is a strand transfer inhibitor of the HIV/SIV (simian immunodeficiency virus) integrase and was shown to be an effective preexposure prophylaxis (PrEP) agent in a low-dose intrarectal SHIV (simian-human immunodeficiency virus) rhesus macaque challenge model. We examined the pharmacokinetics and efficacy of GSK744 LA as PrEP against repeat high-dose intravaginal SHIV challenge in female rhesus macaques treated with Depo-Provera (depot medroxyprogesterone acetate), which promotes viral transmission vaginally. When Depo-Provera-treated female rhesus macaques were dosed with GSK744 LA (50 mg/kg) monthly, systemic and tissue drug concentrations were lower than previously observed in male rhesus macaques. GSK744 concentrations were fivefold lower on average in cervical tissues than in rectal tissues. Eight female rhesus macaques were treated with GSK744 LA at week 0, and four female rhesus macaques served as controls. All animals received a high-dose challenge of SHIV162P3 at week 1. No infection was detected in GSK744 LA-treated rhesus macaques, whereas viremia was detected 1 to 2 weeks after SHIV challenge in all control animals. The GSK744 LA-treated rhesus macaques were given a second administration of drug at week 4 and further challenged at weeks 5 and 7. GSK744 LA treatment protected six of eight female rhesus macaques against three high-dose SHIV challenges, whereas all control animals became infected after the first challenge (P = 0.0003, log-rank test). These results support further clinical development of GSK744 LA for PrEP. Copyright © 2015, American Association for the Advancement of Science.

    Metformin hydrochloride (MTF-HCl) is extensively recommended by physicians for the treatment of polycystic ovary syndrome (PCOS). Mechanistically, MTF-HCl activates AMP-dependent kinase-α (AMPK-α) pathway to decrease the glucose production, enhances fatty acid oxidation and elevates the uptake of glucose in tissues. However, despite favourable physicochemical properties, oral administration of MTF-HCl is associated with impaired bioavailability (50-60%), lactic-acidosis and frequent dosing (500mg 2-3 times a day) in PCOS that ultimately influence the patient compliance. Therefore, in present investigation, MTF-HCl loaded unmodified and cationic small unilamellar niosomes were separately amalgamated with thermosensitive gel (MTF-HCl-SUNs-Gel and MTF-HCl-C-SUNs-Gel) for the treatment of PCOS through vaginal route of administration. MTF-HCl-SUNs and MTF-HCl-C-SUNs were separately prepared by reverse phase evaporation method. The nanovesicle size and zeta-potential of MTF-HCl-C-SUNs were measured to be 210.3±14.8-nm (Ptreatment of PCOS rats under scheduled dose-dosage regimen with oral MTF-HCl solution, intravaginal MTF-HCl-SUNs-Gel and intravaginal MTF-HCl-C-SUNs-gel exhibited remarkable alterations, recruitment and development of normal follicles in addition to normalization of level of various hormones in PCOS. In conclusion, MTF-C-SUNs-Gel has paved the way for developing intravaginal dosage form of MTF-HCl for the treatment of PCOS. Copyright © 2016 Elsevier B.V. All rights reserved.

    The aim of this study is to confirm the local beneficial effects of intravaginal dehydroepiandrosterone (DHEA, Prasterone) on moderate to severe dyspareunia or pain at sexual activity, the most frequent symptom of vulvovaginal atrophy due to menopause or genitourinary syndrome of menopause (GSM). In a prospective, randomized, double-blind, and placebo-controlled phase III clinical trial, the effect of daily intravaginal 0.50% DHEA (6.5 mg) (Prasterone, EndoCeutics) was examined on four coprimary objectives, namely percentage of parabasal cells, percentage or superficial cells, vaginal pH, and moderate to severe pain at sexual activity (dyspareunia) identified by the women as their most bothersome vulvovaginal atrophy symptom. The intent-to-treat population included 157 and 325 women in the placebo and DHEA-treated groups, respectively. After daily intravaginal administration of 0.50% DHEA for 12 weeks, when compared to baseline by the analysis of covariance test, the percentage of parabasal cells decreased by 27.7% over placebo (P < 0.0001), whereas the percentage of superficial cells increased by 8.44% over placebo (P < 0.0001), vaginal pH decreased by 0.66 pH unit over placebo (P < 0.0001), and pain at sexual activity decreased by 1.42 severity score unit from baseline or 0.36 unit over placebo (P = 0.0002). On the other hand, moderate to severe vaginal dryness present in 84.0% of women improved at 12 weeks by 1.44 severity score unit compared to baseline, or 0.27 unit over placebo (P = 0.004). At gynecological evaluation, vaginal secretions, epithelial integrity, epithelial surface thickness, and color all improved by 86% to 121% over the placebo effect (P < 0.0001 for all comparisons with placebo). Serum steroid levels remained well within the normal postmenopausal values according to the involved mechanisms of intracrinology. The only side effect reasonably related to treatment is vaginal discharge due to melting of the vehicle at

    High levels of inflammatory cytokines in the genital tract suggest mucosal vulnerability and increased risk of HIV and sexually transmitted infection (STI) acquisition. Intravaginal douching is associated with bacterial vaginosis (BV) in women in the United States, and both douching and BV are linked to HIV and STI acquisition. This study evaluates inflammatory cytokines in the genital tract to increase understanding of the effects of both BV and intravaginal douching to the vaginal mucosa. A cross-sectional study of participants in the Miami WIHS investigated 72 reproductive age women (45 HIV + and 27 high-risk HIV - ) who completed intravaginal douching questionnaires and underwent collection of vaginal swabs and cervicovaginal lavages (CVLs). BV was assessed using the Nugent score. Inflammatory cytokines in the CVLs (interleukin [IL]-6, IL-8, IL-1α, IL-1β, soluble intracellular adhesion molecule-1 [sICAM-1], interferon [IFN]α2, chemokine C ligand 5 (CCL5), vascular endothelial growth factor (VEGF), monocyte chemotactic protein-1 (MCP1), tumor necrosis factor alpha (TNFα), and secretory leukocyte protease inhibitor [SLPI]) were measured. Fourteen (19%) women reported intravaginal douching; 24 (33%) had BV. BV, intravaginal douching, and HIV were associated with higher levels of inflammatory cytokines. After controlling for demographic and risk factors and HIV status, women who had BV and douched had higher levels of inflammatory cytokines than those without BV and who did not douche, or who only had BV or only douched. These findings suggest that BV and douching are associated with greater mucosal inflammation and may facilitate HIV acquisition and transmission. Although longitudinal studies are needed to determine temporal associations and causality, interventions to decrease rates of intravaginal douching and BV could significantly decrease women's risks of acquiring STIs and HIV and limit the spread of HIV.

    Although various progestagens are often used to induce and synchronize estrus and ovulation in ruminants, concerns regarding residues are the impetus to develop alternative approaches, including reduced doses of progestagens. Therefore, the objective was to determine whether ovarian function was affected by halving the dose of fluorogestone acetate in intravaginal sponges for synchronizing ovulation in sheep during the physiologic breeding season. Twenty Manchega ewes, 4-6-year-old, were randomly allocated to receive an intravaginal sponge containing either 20mg (P20, n=10) or 40 mg of fluorogestone acetate (P40, n=10). Cloprostenol (125 microg) was given at sponge insertion, and all sponges were removed after 6d. Ovarian follicular dynamics (monitored by daily ultrasonography) and other aspects of ovarian function did not differ significantly between the two groups. Ovulatory follicles (OF) grew at a similar growth rate (r=0.62; Pprogesterone concentrations (3.8+/-0.35 ng/mL for P20 and 3.9+/-0.38 ng/mL for P40) were similar. In conclusion, reducing the dose of fluorogestone acetate from 40 to 20mg did not affect significantly ovarian follicular dynamics or other aspects of ovarian function.

    A consensus emerged in the late 1990s among leaders in global maternal health that traditional birth attendants (TBAs) should no longer be trained in delivery skills and should instead be trained as promoters of facility-based care. Many TBAs continue to be trained in places where home deliveries are the norm and the potential impacts of this training are important to understand. The primary objective of this study was to gain a more nuanced understanding of the full impact of training TBAs to use misoprostol and a blood measurement tool (mat) for the prevention of postpartum haemorrhage (PPH) at home deliveries through the perspective of those involved in the project. This qualitative study, conducted between July 2009 and July 2010 in Bangladesh, was nested within larger operations research, testing the feasibility and acceptability of scaling up community-based provision of misoprostol and a blood measurement tool for prevention of PPH. A total of 87 in-depth interviews (IDIs) were conducted with TBAs, community health workers (CHWs), managers, and government-employed family welfare visitors (FWVs) at three time points during the study. Computer-assisted thematic data analysis was conducted using ATLAS.ti (version 5.2). Four primary themes emerged during the data analysis, which all highlight changes that occurred following the training. The first theme describes the perceived direct changes linked to the two new interventions. The following three themes describe the indirect changes that interviewees perceived: strengthened linkages between TBAs and the formal healthcare system; strengthened linkages between TBAs and the communities they serve; and improved quality of services/service utilization. The data indicate that training TBAs and CHW supervisors resulted in perceived broader and more nuanced changes than simply improvements in TBAs' knowledge, attitudes, and practices. Acknowledgeing TBAs' important role in the community and in home deliveries and

Group I (injectable P4/FTAI 36 hours received 250 mg of injectable P4 and 2 mg EB on D0; on D7, they received 500 µg of cloprostenol; on D8, 300 IU of eCG and 1 mg of EB were administered; and finally, FTAI was performed 36 hours after the application of EB. Group II (injectable P4/FTAI 48 hours received the same protocol as Group I, except that the FTAI was performed 48 hours after ovulation induction. The animals of Group III (Control/CIDR received a conventional protocol for FTAI using an intravaginal device (D0: P4 and 2 mg EB; D8: device removal, 500 µg cloprostenol, 300 IU eCG, 1 mg EB; and FTAI performed 48 hours after removal of the device. The results showed that cows synchronized with the conventional protocol for FTAI (Control/CIDR had a higher pregnancy rate (60 %, 27/45 than those synchronized with an injectable P4/FTAI 36 hours (33.33 %; 15/45, P = 0.010. However, the group receiving injectable P4 group/FTAI 48 hours had a similar pregnancy rate (48.9 %; 22/45; P = 0.290 when compared to both the group receiving the conventional protocol and that receiving injectable P4/FTAI 36 hours (P = 0.134. Although the injectable P4 may affect pregnancy rate with the FTAI performed in 36 hours, we found similar pregnancy rates from cows inseminated 48 hours after induction ovulation, considering injectable or intravaginal P4. Therefore, we suggest that

    The aim of this study was to compare plasma progesterone (P4) concentrations in nonlactating, multiparous Holstein cows (n = 24) treated with 2 types of intravaginal implants containing either 1.0 or 1.9 g of P4 either at the first use or during reuse of the implants after sanitizing the implant by autoclave or chemical disinfection. In a completely randomized design with a 2 × 3 factorial arrangement and 2 replicates, every cow underwent 2 of 6 treatments. Two sources of P4 [controlled internal drug release (1.9 g of P4) from Zoetis (São Paulo, Brazil), and Sincrogest (1.0 g of P4) from Ourofino (Cravinhos, Brazil)] and 3 types of processing, new (N), reused after autoclave (RA), and reused after chemical disinfection (RC), were used. After inducing luteolysis to avoid endogenous circulating P4, the cows were randomized in 1 of 6 treatments (1.9 g of N, 1.9 g of RA, 1.9 g of RC, 1.0 g of N, 1.0 g of RA, and 1.0 g RC). Cows were treated with the implants for 8 d and during this period blood samples were collected at 0, 2, 12, 24, 48, 72, 96, 120, 144, 168, and 192 h. Statistical analyses were performed using Proc-Mixed and the mean ± standard error of the mean P4 concentrations were calculated using the Proc-Means procedures of SAS 9.4 (SAS Institute Inc., Cary, NC). No interaction between treatments was observed. Comparing types of implant, average P4 concentrations during treatments were greater for 1.9 g than 1.0 g (1.46 vs. 1.14 ± 0.04 ng/mL). When types of processing were compared, average P4 concentrations did not differ between autoclaved and new inserts (1.46 vs. 1.37 ± 0.05 ng/mL; respectively), but both were greater than chemically disinfected implants (1.09 ± 0.04 ng/mL). Within 1.9-g P4 inserts, P4 concentrations from autoclaved implants were greater than new, which were greater than chemically disinfected (1.67 ± 0.06 vs. 1.49 ± 0.07 vs. 1.21 ± 0.05 ng/mL; respectively). For 1.0-g P4 implants, P4 concentrations from autoclaved did not differ

    Purpose: The objective of this study was to determine the patient- and treatment-related prognostic factors associated with vaginal toxicity in patients who received intravaginal high dose rate (HDR) brachytherapy alone as adjuvant treatment for endometrial cancer. Secondary goals of this study included a quantitative assessment of optimal dilator use frequency and a crude assessment of clinical predictors for compliant dilator use. Methods and Materials: We retrospectively reviewed the charts of 100 patients with histologically confirmed endometrial cancer who underwent total hysterectomy and bilateral salpingo-oophorectomy with or without lymph node dissection and adjuvant intravaginal brachytherapy between 1995 and 2009 at the Hospital of University of Pennsylvania. The most common treatment regimen used was 21 Gy in three fractions (71 patients). Symptoms of vaginal mucosal toxicity were taken from the history and physical exams noted in the patients’ charts and were graded according to the Common Toxicity Criteria for Adverse Events v. 4.02. Results: The incidence of Grade 1 or asymptomatic vaginal toxicity was 33% and Grade 2–3 or symptomatic vaginal toxicity was 14%. Multivariate analysis of age, active length, and dilator use two to three times a week revealed odds ratios of 0.93 (p = 0.013), 3.96 (p = 0.008), and 0.17 (p = 0.032) respectively. Conclusion: Increasing age, vaginal dilator use of at least two to three times a week, and shorter active length were found to be significantly associated with a decreased risk of vaginal stenosis. Future prospective studies are necessary to validate our findings.

    Advance provision of misoprostol to women during antenatal care aims to achieve broader access to uterotonics for the prevention of postpartum hemorrhage. Studies of this community-based approach usually involve antenatal education as well as timely postpartum follow-up visits to confirm maternal and neonatal outcomes. The MamaMiso study in Mbale, Uganda sought to assess the feasibility of conducting follow-up visits in the postpartum period following advance provision of misoprostol for postpartum hemorrhage prevention. MamaMiso recruited women during antenatal care visits. Participants were asked to contact the research team within 48 h of giving birth so that postpartum follow-up visits could be carried out at their homes. Women's baseline and delivery characteristics were collected and analyzed with respect to follow-up time ('on time' ≤ 7 days, 'late' > 7 days, and 'lost to follow up'). Every woman who was followed up late due to a failure to report the delivery was asked for the underlying reasons for the delay. When attempts at following up participants were unsuccessful, a file note was generated explaining the details of the failure. We abstracted data and identified themes from these notes. Of 748 recruited women, 700 (94%) were successfully followed up during the study period, 465 (62%) within the first week postpartum. The median time to follow up was 4 days and was similar for women who delivered at home or in facilities and for women who had attended or unattended births. Women recruited at the urban hospital site (as opposed to rural health clinics) were more likely to be lost to follow up or followed up late. Of the women followed up late, 202 provided a reason. File notes explaining failed attempts at follow up were generated for 164 participants. Several themes emerged from qualitative analysis of these notes including phone difficulties, inaccurate baseline information, misperceptions, postpartum travel, and the condition of the mother

    Some types of intravaginal practices (IVP) may increase the risk for HIV acquisition. This is particularly worrisome for populations with dual high prevalence of HIV and IVP. Women involved in transactional sex are at increased risk for HIV infection in sub-Saharan Africa. Social, cultural and economic influences are strong drivers of IVP in this population. To explore this, we carried out a qualitative research study to investigate the drivers and motivations for using IVP within a large observational study of women at high risk of HIV in Tanzania and Uganda from September 2008 to September 2009. Of the 201 women selected, 176 women took part in a semi-structured in-depth interview. Additionally, in Tanzania, eight focus group discussions among study participants and community members were carried out to obtain information on community norms and expectations. IVP were motivated by overlapping concerns with hygiene, morality, sexual pleasure, fertility, relationship security, and economic security. These motives were driven by the need to meet cultural and social expectations of womanhood, and at the same time attend to personal well-being. Among women involved in transactional sex in East Africa, interventions aimed at modifying or eliminating IVP should attend to local cultural and social norms as well as the individual as an agent of change.

    The broadly neutralizing antibody (bNAb) VRC01, capable of neutralizing 91% of known human immunodeficiency virus type 1 (HIV-1) isolates in vitro , is a promising candidate microbicide for preventing sexual HIV infection when administered topically to the vagina; however, accessibility to antibody-based prophylactic treatment by target populations in sub-Saharan Africa and other underdeveloped regions may be limited by the high cost of conventionally produced antibodies and the limited capacity to manufacture such antibodies. Intravaginal rings of the pod design (pod-IVRs) delivering Nicotiana -manufactured VRC01 (VRC01-N) over a range of release rates have been developed. The pharmacokinetics and preliminary safety of VRC01-N pod-IVRs were evaluated in a rhesus macaque model. The devices sustained VRC01-N release for up to 21 days at controlled rates, with mean steady-state VRC01-N levels in vaginal fluids in the range of 10 2 to 10 3 μg g -1 being correlated with in vitro release rates. No adverse safety indications were observed. These findings indicate that pod-IVRs are promising devices for the delivery of the candidate topical microbicide VRC01-N against HIV-1 infection and merit further preclinical evaluation.

    Posterior intravaginal slingplasty (IVS) is a technique used for the treatment of apical prolapse. Type III meshes have been mostly used with this technique. In this article, a case of bilateral gluteo-vaginal sinus tract formation that complicated a posterior vaginal slingplasty with a type III mesh is presented. At 3 months follow-up, the patient complained for bulking through the vagina, continuous offensive vaginal discharge, and constant pain at the buttocks. She had prolapse recurrence, and there was defective healing at the gluteal entry points of the posterior IVS. Ten months after the initial surgery, she underwent a laparotomic subtotal hysterectomy and sacrocervicopexy with prolene type I mesh. At the same time, the posterior mesh was removed allowing the surgeon to discover communication of the canal of the mesh extending from gluteal incisions to the vagina epithelium. The sinus tract was managed surgically with excision of the surrounding tissues. There was no recurrence or other complications at 2 months follow-up.

    Urinary tract infections (UTIs) are common among women and frequently recur. Depletion of vaginal lactobacilli is associated with UTI risk, which suggests that repletion may be beneficial. We conducted a double-blind placebo-controlled trial of a Lactobacillus crispatus intravaginal suppository probiotic (Lactin-V; Osel) for prevention of recurrent UTI in premenopausal women. One hundred young women with a history of recurrent UTI received antimicrobials for acute UTI and then were randomized to receive either Lactin-V or placebo daily for 5 d, then once weekly for 10 weeks. Participants were followed up at 1 week and 10 weeks after intervention and for UTIs; urine samples for culture and vaginal swabs for real-time quantitative 16S ribosomal RNA gene polymerase chain reaction for L. crispatus were collected. Recurrent UTI occurred in 7/48 15% of women receiving Lactin-V compared with 13/48 27% of women receiving placebo (relative risk [RR], .5; 95% confidence interval, .2-1.2). High-level vaginal colonization with L. crispatus (≥10(6) 16S RNA gene copies per swab) throughout follow-up was associated with a significant reduction in recurrent UTI only for Lactin-V (RR for Lactin-V, .07; RR for placebo, 1.1; P < .01). Lactin-V after treatment for cystitis is associated with a reduction in recurrent UTI. Larger efficacy trials of this novel preventive method for recurrent UTI are warranted.

    The scandal of the Mediator® case led the legislature to take measures in order to regulate off-label drugs prescriptions. Indeed the law issued in December 29th, 2011 on strengthening the safety of drugs and all derivative health products came to pave the way for an "over-cautious" practice of medicine in line with the precautionary principle erected as a constitutional principle. The supervision of off-label prescribing has had a direct impact on the exercise of the medical profession and has resurrected the issues related to the freedom of prescription, the obligation to provide information to patients and in general their whole responsibility. It is important to mention that the prescribing act is part of the freedom and the strict prerogative of those skilled in the art: the physician in this case. The off-label prescription is commonly accepted in certain specialties, such as anesthesia and intensive care, oncology or pediatrics where it is even subject of a memorandum of use because of concerns regarding the availability of forms adapted to children. However, the physician must ensure that no appropriate therapeutic alternative is available and inform the patient, fundamental principle of the right to respect for the will of the person. Off-label use of the prostaglandin-E1 analogue misoprostol in obstetrics and gynecology is a good example. In fact, this drug obtained a marketing authorization for the treatment or prevention of peptic ulcers and other stomach disorders, is commonly used off-label when inducing labour or intrauterine device insertion. These are the issues that need to be clarify and carefully assessed in order to help physicians to understand the impact of the law and the state of the jurisprudence on the exercise of their profession.

Intravaginal algometer measurement of tenderness to pressure applied to the pelvic floor muscles helps define vulvodynia associated with musculoskeletal factors. Women with both vulvodynia and fibromyalgia might have increased pelvic muscle pain compared to women with vulvodynia alone, defining the possible link of these 2 conditions. We sought to: (1) correlate pain intensity during the nongenital tender point tenderness examination to pain intensity with the vaginal algometer in women with provoked vestibulodynia, and (2) determine whether subjects with provoked vestibulodynia and fibromyalgia had higher pain intensity scores with the vaginal algometer than those without fibromyalgia. In all, 92 subjects referred for vulvar pain were confirmed to have provoked vestibulodynia using the cotton swab test. A diagnosis of fibromyalgia was made if pain was present (numeric rating scale >1) in at least 11 sites of the 18-point nongenital tender point tenderness exam. Vaginal pain sensitivity was measured using an intravaginal pressure algometer, where 0.1, 0.3, and 0.5 kg/cm 2 forces were applied digitally in random assignment by force and location to the right and left iliococcygeus muscle regions and the posterior vaginal wall. Both tender point tenderness and algometer pain intensity were reported on a 0 (no pain) to 10 (worse pain) numeric rating scale. Correlations were computed between the composite pain intensity (total of rating scale from each pressure threshold at specified site) of nongenital and those of iliococcygeus regions and the posterior vaginal wall. Independent t tests were used to determine differences in iliococcygeus regions and the posterior vaginal algometer pain ratings and presence or absence of fibromyalgia. The significance level was at P pain

    Background Vulvodynia is a chronic vulvar pain disorder and fibromyalgia is a chronic widespread musculoskeletal pain disorder; both of unknown etiology. Association of these conditions is well documented. Intra-vaginal algometer measurement of tenderness to pressure applied to the pelvic floor muscles helps to define vulvodynia associated with musculoskeletal factors. Women with both vulvodynia and fibromyalgia might have increased pelvic muscle pain compared to women with vulvodynia alone, defining the possible link of these two conditions. Objective 1) correlate pain intensity during the non-genital tender point tenderness examination to pain intensity with the vaginal algometer in women with provoked vestibulodynia, 2) determine whether subjects with provoked vestibulodynia and fibromyalgia had higher pain intensity scores with the vaginal algometer than those without fibromyalgia. Study Design Ninety-two subjects referred for vulvar pain were confirmed to have provoked vestibulodynia using the cotton swab test. A diagnosis of fibromyalgia was made if pain was present (Numerical rating scale> 1) in at least 11 sites of the 18-point non-genital tender point tenderness exam. Vaginal pain sensitivity was measured using an intra-vaginal pressure algometer, where 0.1, 0.3, and 0.5 kg/cm2 forces were applied digitally in random assignment by force and location to the right and left iliococcygeus muscle regions and the posterior vaginal wall. Both tender point tenderness and algometer pain intensity were reported on a 0 (no pain) to 10 (worse pain) numeric rating scale. Correlations were computed between the composite pain intensity (total of rating scale from each pressure threshold at specified site) of non-genital and those of iliococcygeus regions and the posterior vaginal wall. Independent t-tests were used to determine differences in iliococcygeus regions and the posterior vaginal algometer pain ratings and presence or absence of fibromyalgia. The significance

    We previously showed that a carrageenan (CG) gel containing 50 μM MIV-150 (MIV-150/CG) reduced vaginal simian/human immunodeficiency virus (SHIV)-RT infection of macaques (56%, p>0.05) when administered daily for 2 weeks with the last dose given 8 h before challenge. Additionally, when 100 mg of MIV-150 was loaded into an intravaginal ring (IVR) inserted 24 h before challenge and removed 2 weeks after challenge, >80% protection was observed (p<0.03). MIV-160 is a related NNRTI with a similar IC(50), greater aqueous solubility, and a shorter synthesis. To objectively compare MIV-160 with MIV-150, herein we evaluated the antiviral effects of unformulated MIV-160 in vitro as well as the in vivo protection afforded by MIV-160 delivered in CG (MIV-160/CG gel) and in an IVR under regimens used with MIV-150 in earlier studies. Like MIV-150, MIV-160 exhibited potent antiviral activity against SHIV-RT in macaque vaginal explants. However, formulated MIV-160 exhibited divergent effects in vivo. The MIV-160/CG gel offered no protection compared to CG alone, whereas the MIV-160 IVRs protected significantly. Importantly, the results of in vitro release studies of the MIV-160/CG gel and the MIV-160 IVR suggested that in vivo efficacy paralleled the amount of MIV-160 released in vitro. Hundreds of micrograms of MIV-160 were released daily from IVRs while undetectable amounts of MIV-160 were released from the CG gel. Our findings highlight the importance of testing different modalities of microbicide delivery to identify the optimal formulation for efficacy in vivo.

    MR imaging was performed using a 1.0 T unit. In 10 females (6 nullipara, one primipara without and three primipara with postpartum faecal incontinence) a surface coil, originally designed for endorectal use, was placed into the vagina. Transverse oblique T{sub 1}-weighted spin echo and double echo turbo spin echo sequences with T{sub 2}- and proton density-weighting were acquired parallel to the puborectal, rectococcygeal and anorectal planes. Three readers analysed the images in consensus. The anatomic structures of the external and internal sphincter as well as the mucosa were differentiated in all cases with a good contrast. The best results were yielded by the proton density weighting. In one case of faecal incontinence a sphincter defect after repair of a complete rupture of the anal sphincter was shown. In another case irregularities in the structure of the external sphincter and perineum were visualised.

Bei 10 Frauen (6 Nulliparae, eine Primipara ohne und drei Primiparae mit postpartaler Stuhlinkontinenz) wurde eine Oberflaechenspule, die urspruenglich zur endorektalen Anwendung konzipiert war, intravaginal eingefuehrt. Es wurden T{sub 1}-gewichtete Spin-Echo-Sequenzen sowie Doppel-Echo-Turbo-Spin-Echo-Sequenzen mit T{sub 2}- und Protonendichtegewichtung parallel zur puborektalen, rektokokzygealen und anorektalen Ebene akquiriert. Drei Auswerter analysierten die Aufnahmen im Konsensmodus. Die anatomischen Strukturen des Musculus sphincter ani externus und internus sowie die Mukosa konnten in allen Faellen gut differenziert werden. Das beste Ergebnis wurde mit der Protonendichte-Gewichtung erzielt. In einem Fall von Stuhlinkontinenz zeigte sich ein kombinierter Defekt des M. sphincter ani internus und externus nach Naht eines Dammrisses III. Grades. In einem weiteren Fall waren Irregularitaeten im Perineum und externen Sphinkteranteil darzustellen. (orig./MG)

    Full Text Available It has been postulated that the persistent short intravaginal ejaculation latency time (IELT of men with lifelong premature ejaculation (LPE is related to 5-hydroxytryptamine (HT2C receptor functioning. The aim of this study was to investigate the relationship of Cys23Ser 5-HT2C receptor gene polymorphism and the duration of IELT in men with LPE. Therefore, a prospective study was conducted in 64 Dutch Caucasian men with LPE. Baseline IELT during coitus was assessed by stopwatch over a 1-month period. All men were genotyped for Cys23Ser 5-HT2C receptor gene polymorphism. Allele frequencies and genotypes of Cys and Ser variants of 5-HT2C receptor gene polymorphism were determined. Association between Cys/Cys and Ser/Ser genotypes and the natural logarithm of the IELT in men with LPE were investigated. As a result, the geometric mean, median and natural mean IELT were 25.2, 27.0, 33.9 s, respectively. Of all men, 20.0%, 10.8%, 23.1% and 41.5% ejaculated within 10, 10-20, 20-30 and 30-60 s after vaginal penetration. Of the 64 men, the Cys/Cys and Ser/Ser genotype frequency for the Cys23Ser polymorphism of the 5-HT2C receptor gene was 81% and 19%, respectively. The geometric mean IELT of the wildtypes (Cys/Cys is significantly lower (22.6 s; 95% CI 18.3-27.8 s than in male homozygous mutants (Ser/Ser (40.4 s; 95% CI 20.3-80.4 s (P = 0.03. It is concluded that Cys23Ser 5-HT2C receptor gene polymorphism is associated with the IELT in men with LPE. Men with Cys/Cys genotype have shorter IELTs than men with Ser/Ser genotypes.

    Full Text Available Purpose: To find the most accurate mathematical description of the intravaginal ejaculation latency time (IELT distribution in the general male population. Materials and Methods: We compared the fitness of various well-known mathematical distributions with the IELT distribution of two previously published stopwatch studies of the Caucasian general male population and a stopwatch study of Dutch Caucasian men with lifelong premature ejaculation (PE. The accuracy of fitness is expressed by the Goodness of Fit (GOF. The smaller the GOF, the more accurate is the fitness. Results: The 3 IELT distributions are gamma distributions, but the IELT distribution of lifelong PE is another gamma distribution than the IELT distribution of men in the general male population. The Lognormal distribution of the gamma distributions most accurately fits the IELT distribution of 965 men in the general population, with a GOF of 0.057. The Gumbel Max distribution most accurately fits the IELT distribution of 110 men with lifelong PE with a GOF of 0.179. There are more men with lifelong PE ejaculating within 30 and 60 seconds than can be extrapolated from the probability density curve of the Lognormal IELT distribution of men in the general population. Conclusions: Men with lifelong PE have a distinct IELT distribution, e.g., a Gumbel Max IELT distribution, that can only be retrieved from the general male population Lognormal IELT distribution when thousands of men would participate in a IELT stopwatch study. The mathematical formula of the Lognormal IELT distribution is useful for epidemiological research of the IELT.

    Lifelong premature ejaculation (LPE) is characterized by persistent intravaginal ejaculation latency times (IELTs) of less than 1 min, and has been postulated as a neurobiological dysfunction related to diminished serotonergic neurotransmission with 5-HT₁A receptor hyperfunction and 5-HT₂C hypofunction. To investigate the relationship between 5-HT₁A receptor gene (HTR₁A)-C(1019)G promoter polymorphism and IELT in men with LPE. This polymorphism is known to increase 5-HT1A receptor expression. A prospective study was conducted in 54 Dutch Caucasian men with LPE. Baseline IELT during coitus was assessed by stopwatch over a 1-month period. All men were genotyped for HTR₁A gene polymorphism. Allele frequencies and genotypes of C and G variants of HTR₁A polymorphism were determined. Association between CC, CG, and GG genotypes and the IELT in men with LPE were investigated. IELT measured by stopwatch, HTR₁A polymorphism. In this cohort of men with LPE, the geometric mean IELT was 23.8 s. Of the 54 men, the CC, CG and GG genotype frequency for the C(1019)G polymorphism of the 5-HT₁A gene was 33%, 43% and 24%, respectively. The geometric mean IELT for the CC, CG and GG genotypes were 14.5, 27.7 and 36.0 s, respectively (p=0.019). Compared to GG and CG genotypes, men with CC genotype had a 250% and 190% shorter ejaculation time, respectively. HTR₁A gene polymorphism is associated with the IELT in men with LPE. Men with CC genotype have shorter IELTs than men with GG and CG genotypes. Copyright © 2014 Elsevier Inc. All rights reserved.

    Lifelong premature ejaculation (LPE) is characterized by persistent intravaginal ejaculation latency times (IELTs) of less than 1 minute, and has been postulated as a neurobiological dysfunction with genetic vulnerability for the short IELTs, related to disturbances of central serotonin (5-hydroxytryptamine [5-HT]) neurotransmission and 5-HT receptor functioning. To investigate the relationship between 5-HT transporter gene-linked polymorphism (5-HTTLPR) and short IELTs in men with lifelong PE. A prospective study was conducted in 89 Dutch Caucasian men with lifelong PE. IELT during coitus was assessed by stopwatch over a 1-month period. Controls consisted of 92 Dutch Caucasian men. All men with LPE were genotyped for a 5-HTT-promoter polymorphism. Allele frequencies and genotypes of short (S) and long (L) variants of 5-HTTLPR polymorphism were compared between patients and controls. Association between LL, SL, and SS genotypes, and the natural logarithm of the IELT in men with LPE was investigated. IELT measured by stopwatch, 5-HTTLPR polymorphism. In men with lifelong PE, the geometric mean, median, and natural mean IELTs were 21, 26, and 32 seconds, respectively. There were no significant differences in the 5-HTT polymorphism alleles and genotypes between 89 Dutch Caucasian men with LPE (S 47%, L 53%/LL 29%, SL 48%, SS 22%) and 92 Dutch Caucasian controls (S 48%, L 52%/LL 29%, SL 45%, SS 26%). In men with lifelong PE there was a statistically significant difference between LL, SL, and SS genotypes in their geometric mean IELT (P IELTs than the SS and SL genotypes. The 5-HTTLPR polymorphism is associated with significant effects on the latency to ejaculate in men with lifelong PE. Men with SS and SL genotypes have 100% and 90% longer ejaculation time, respectively than men with LL genotypes.

    The development of a chlamydial vaccine that elicits protective mucosal immunity is of paramount importance in combatting the global spread of sexually transmitted Chlamydia trachomatis (Ct) infections. While the identification and prioritization of chlamydial antigens is a crucial prerequisite for efficacious vaccine design, it is likely that novel adjuvant development and selection will also play a pivotal role in the translational potential of preclinical Ct vaccines. Although the molecular nature of the immuno-modulatory component is of primary importance, adjuvant formulation and delivery systems may also govern vaccine efficacy and potency. Our study provides the first preclinical evaluation of recombinant Ct polymorphic membrane protein D (rPmpD) in combination with three different formulations of a novel second-generation lipid adjuvant (SLA). SLA was rationally designed in silico by modification of glucopyranosyl lipid adjuvant (GLA), a TLR4 agonistic precursor molecule currently in Phase II clinical development. We demonstrate robust protection against intra-vaginal Ct challenge in mice, evidenced by significantly enhanced resistance to infection and reduction in mean bacterial load. Strikingly, protection was found to correlate with the presence of robust anti-rPmpD serum and cervico-vaginal IgG titres, even in the absence of adjuvant-induced Th1-type cellular immune responses elicited by each SLA formulation, and we further show that anti-rPmpD antibodies recognize Ct EBs. These findings highlight the utility of SLA and rational molecular design of adjuvants in preclinical Ct vaccine development, but also suggest an important role for anti-rPmpD antibodies in protection against urogenital Ct infection.

    The aim of this study was to develop, characterize and evaluate a mucoadhesive caplet resulting from a polymeric blend (polymeric caplet) for intravaginal anti-HIV-1 delivery. Poly(lactic-co-glycolic) acid, ethylcellulose, poly(vinylalcohol), polyacrylic acid and modified polyamide 6, 10 polymers were blended and compressed to a caplet-shaped device, with and without two model drugs 3'-azido-3'-deoxythymidine (AZT) and polystyrene sulfonate (PSS). Thermal analysis, infrared spectroscopy and microscopic analysis were carried out on the caplets employing temperature-modulated DSC (TMDSC), Fourier transform infra-red (FTIR) spectrometer and scanning electron microscope, respectively. In vitro and in vivo drug release analyses as well as the histopathological toxicity studies were carried out on the drug-loaded caplets. Furthermore, molecular mechanics (MM) simulations were carried out on the drug-loaded caplets to corroborate the experimental findings. There was a big deviation between the Tg of the polymeric caplet from the Tg's of the constituent polymers indicating a strong interaction between constituent polymers. FTIR spectroscopy confirmed the presence of specific ionic and non-ionic interactions within the caplet. A controlled near zero-order drug release was obtained for AZT (20 d) and PSS (28 d). In vivo results, i.e. the drug concentration in plasma ranged between 0.012-0.332 mg/mL and 0.009-0.256 mg/mL for AZT and PSS over 1-28 d. The obtained results, which were corroborated by MM simulations, attested that the developed system has the potential for effective delivery of anti-HIV-agents.

    Dapivirine is a nonnucleoside reverse transcriptase inhibitor being developed as a topical microbicide for the prevention of human immunodeficiency virus infection. The distribution of radioactivity and drug in plasma and in vaginal, cervical, and draining lymph node tissues was investigated after daily application of a vaginal gel formulation of [14C]dapivirine to rhesus macaques. This was preceded by a preliminary study with rabbits. Following the intravaginal administration of [14C]dapivirine ( approximately 0.1 mg/ml [15 microCi/ml]) to rabbits (0.5 ml/day) and macaques (1 ml/day) for 7 days, the dapivirine levels associated with vaginal and cervical tissue samples 1 h after the final dose were high (quantities of microg/g of tissue) and remained detectable at 24 h (mean, >or=2.5 ng/g in rabbits) and 48 h (mean, >80 ng/g in macaques). Radioactivity levels were low in the plasma and very low or unquantifiable in the draining lymph nodes of the macaques. Microautoradiography identified drug-related material (DRM) on the surfaces of the vaginal and cervical tissues of the rabbits and macaques. Although DRM was primarily associated with the outermost layer of shedding cells in rabbits, two animals showed some evidence of small quantities in the mucosal epithelium of the cervix. In macaques, DRM was seen within the keratinized layer of the vaginal epithelium and and was found to extend into the superficial cellular layers, and in at least one animal it appeared to be present in the deepest (germinal) layer of the epithelium and in submucosal tissues. The persistence of biologically significant concentrations of dapivirine in vaginal and cervical tissues for >24 h supports the development of dapivirine as a microbicide for once daily application.

    Although the female genital tract is the main portal of entry for sexually transmitted infections in women, we still have limited understanding of the generation, maintenance and characteristics of memory T cells in the local tissue. Here, we utilized a mouse model of intravaginal HSV-2 infection and tetramers against the immunodominant HSV glycoprotein B epitope recognized by CD8+ T cells to examine the generation, maintenance and characteristics of anti-HSV memory T cells in the genital tract following acute infection. Our results show that the highest percentage of HSVgB-specific CD8+ T cells was found in the genital tract compared to the spleen or iliac lymphnode. Indeed, although the actual number of CD8+ T cells contracted following viral clearance, approximately one quarter of the CD8+ population that remained in the genital tissue was HSVgB-specific. Memory gB-tetramer+CD8 T cells in the genital tract were positive for CD127 and KLRG1 and negative for CD62L and CCR7, thus confirming that HSV-specific CD8 cells were effector memory T cells that lack the capacity for homing to lymphoid tissues. Functionally, both memory CD8+ and CD4+ HSV-specific populations in the genital tract produced IFNγ when stimulated in vitro and CD4+ cells also produced TNFα. Genital HSVgB-specific memory T cells expressed tissue-homing integrins CD103 (αE integrin) and CD49a (VLA-1 or α1 integrin). Our findings suggest that HSV-specific memory T cells are retained in the genital tract, poised to act as an early line of defense against future virus encounter.

    Bacterial vaginosis (BV) is associated with an increased risk of HIV transmission, and intravaginal practices (IVP) are an important risk factor for developing BV. The relationship between IVP, BV and HIV lower genital shedding, responsible for HIV transmission, has not been examined in women receiving antiretrovirals in Zambia. Cross-sectional study. Community Health Center in Lusaka, Zambia. Participants were HIV-infected women receiving antiretroviral therapy and engaging in IVP (n=128). Participants completed audio computer-administered self-interviews to assess IVP and underwent a vaginal examination. BV was diagnosed using Nugent criteria. HIV-1 lower genital shedding was assessed by measuring HIV-1 RNA in cervicovaginal lavages. Most women engaged in IVP daily (114, 89.0%) and 81 (63.3%) of the participants had BV. HIV-1 genital shedding was detected in 18 (14.2%) participants. BV was associated with daily use of IVP (prevalence ratio, PR=4.58, CI 1.26 to 16.64, p=0.02) and weekly use of traditional medicines for IVP (PR=1.33, CI 1.05 to 1.68, p=0.02). The only factor associated with HIV-1 lower genital shedding was plasma viraemia (PR=4.61, CI 2.02 to 10.54, pHIV shedding. Despite the frequency of IVP and high prevalence of BV, plasma viraemia was the primary factor associated with HIV lower genital shedding. These findings support early initiation of antiretrovirals as an HIV prevention tool. Given adverse health outcomes associated with BV, the association between frequent IVP and BV, and the powerful local norms and traditions encouraging IVP, there is a need for studies assessing culturally tailored interventions to decrease BV in high-prevalence settings.

    Some factors associated with the four premature ejaculation (PE) syndromes have been studied, but the association between International Prostate Symptom Score (IPSS) and the four PE syndromes has not been investigated. We performed this study to evaluate the association between IPSS and intravaginal ejaculatory latency time (IELT) in men with the four PE syndromes. From June 2012 to January 2014, a total of 690 men aged 40-59 years complaining of ejaculating prematurely and another 452 male healthy subjects of the same age without these complaints were included in this study. Men with the complaints of ejaculating prematurely were classified as one of the four PE syndromes: lifelong PE, acquired PE (APE), variable PE, and subjective PE. Each of them completed a detailed questionnaire including information on demographics, medical and sexual history (e.g., self-estimated IELT), IPSS, and International Index of Erectile Function-5. Associations between IPSS and self-estimated IELT in middle-aged men with the four PE syndromes. Men complaining of ejaculating prematurely reported higher IPSS (11.2 ± 6.0 vs. 5.5 ± 3.3 ) and shorter self-estimated IELT (2.1 ± 1.6 minutes vs. 4.8 ± 3.3) than men without complaints (P men with the four PE syndromes showed significant correlations with IPSS (P men with PE complaints (adjusted r = -0.378, P men with APE (adjusted r = -0.502, P Men complaining of ejaculating prematurely reported worse IPSS than men without these complaints. Self-estimated IELT was negatively associated with IPSS in men complaining of ejaculating prematurely, and the correlation was the strongest in men with APE. © 2015 International Society for Sexual Medicine.

    Purpose To find the most accurate mathematical description of the intravaginal ejaculation latency time (IELT) distribution in the general male population. Materials and Methods We compared the fitness of various well-known mathematical distributions with the IELT distribution of two previously published stopwatch studies of the Caucasian general male population and a stopwatch study of Dutch Caucasian men with lifelong premature ejaculation (PE). The accuracy of fitness is expressed by the Goodness of Fit (GOF). The smaller the GOF, the more accurate is the fitness. Results The 3 IELT distributions are gamma distributions, but the IELT distribution of lifelong PE is another gamma distribution than the IELT distribution of men in the general male population. The Lognormal distribution of the gamma distributions most accurately fits the IELT distribution of 965 men in the general population, with a GOF of 0.057. The Gumbel Max distribution most accurately fits the IELT distribution of 110 men with lifelong PE with a GOF of 0.179. There are more men with lifelong PE ejaculating within 30 and 60 seconds than can be extrapolated from the probability density curve of the Lognormal IELT distribution of men in the general population. Conclusions Men with lifelong PE have a distinct IELT distribution, e.g., a Gumbel Max IELT distribution, that can only be retrieved from the general male population Lognormal IELT distribution when thousands of men would participate in a IELT stopwatch study. The mathematical formula of the Lognormal IELT distribution is useful for epidemiological research of the IELT. PMID:26981594

  19. Rationale and Safety Assessment of a Novel Intravaginal Drug-Delivery System with Sustained DL-Lactic Acid Release, Intended for Long-Term Protection of the Vaginal Microbiome.

    Bacterial vaginosis is a prevalent state of dysbiosis of the vaginal microbiota with wide-ranging impact on human reproductive health. Based on recent insights in community ecology of the vaginal microbiome, we hypothesize that sustained vaginal DL-lactic acid enrichment will enhance the recruitment of lactobacilli, while counteracting bacterial vaginosis-associated bacteria. We therefore aimed to develop an intravaginal device that would be easy to insert and remove, while providing sustained DL-lactic acid release into the vaginal lumen. The final prototype selected is a vaginal ring matrix system consisting of a mixture of ethylene vinyl acetate and methacrylic acid-methyl methacrylate copolymer loaded with 150 mg DL-lactic acid with an L/D-lactic acid ratio of 1:1. Preclinical safety assessment was performed by use of the Slug Mucosal Irritation test, a non-vertebrate assay to evaluate vaginal mucosal irritation, which revealed no irritation. Clinical safety was evaluated in a phase I trial with six healthy nulliparous premenopausal volunteering women, with the investigational drug left in place for 7 days. Colposcopic monitoring according to the WHO/CONRAD guidelines for the evaluation of vaginal products, revealed no visible cervicovaginal mucosal changes. No adverse events related to the investigational product occurred. Total release from the intravaginal ring over 7 days was estimated through high performance liquid chromatography at 37.1 (standard deviation 0.9) mg DL-lactic acid. Semisolid lactic acid formulations have been studied to a limited extent in the past and typically consist of a large volume of excipients and very high doses of lactic acid, which is of major concern to mucosal safety. We have documented the feasability of enriching the vaginal environment with pure DL-lactic acid with a prototype intravaginal ring. Though the efficacy of this platform remains to be established possibly requiring further development, this approach may offer a

    Full Text Available La energía potencial del agua presenta diferencias de un punto del suelo a otro; esas diferencias son las que originan el movimiento del agua de acuerdo a la tendencia universal de la materia en el sentido de moverse de donde la energía potencial es mayor a donde dicha energía es menor. En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo. El concepto Potencial de agua del suelo es un criterio para esta energía.

    Globally, women bear an uneven burden for sexual HIV acquisition. Results from two clinical trials evaluating intravaginal rings (IVRs) delivering the antiretroviral agent dapivirine have shown that protection from HIV infection can be achieved with this modality, but high adherence is essential. Multipurpose prevention technologies (MPTs) can potentially increase product adherence by offering protection against multiple vaginally transmitted infections and unintended pregnancy. Here we describe a coitally independent, long-acting pod-IVR MPT that could potentially prevent HIV and HSV infection as well as unintended pregnancy. The pharmacokinetics of MPT pod-IVRs delivering tenofovir alafenamide hemifumarate (TAF2) to prevent HIV, acyclovir (ACV) to prevent HSV, and etonogestrel (ENG) in combination with ethinyl estradiol (EE), FDA-approved hormonal contraceptives, were evaluated in pigtailed macaques (N = 6) over 35 days. Pod IVRs were exchanged at 14 days with the only modification being lower ENG release rates in the second IVR. Plasma progesterone was monitored weekly to determine the effect of ENG/EE on menstrual cycle. The mean in vivo release rates (mg d-1) for the two formulations over 30 days ranged as follows: TAF2 0.35-0.40; ACV 0.56-0.70; EE 0.03-0.08; ENG (high releasing) 0.63; and ENG (low releasing) 0.05. Mean peak progesterone levels were 4.4 ± 1.8 ng mL-1 prior to IVR insertion and 0.075 ± 0.064 ng mL-1 for 5 weeks after insertion, suggesting that systemic EE/ENG levels were sufficient to suppress menstruation. The TAF2 and ACV release rates and resulting vaginal tissue drug concentrations (medians: TFV, 2.4 ng mg-1; ACV, 0.2 ng mg-1) may be sufficient to protect against HIV and HSV infection, respectively. This proof of principle study demonstrates that MPT-pod IVRs could serve as a potent biomedical prevention tool to protect women's sexual and reproductive health and may increase adherence to HIV PrEP even among younger high-risk populations.

    The objective was to investigate the ovarian response of Brahman heifers to two modified ovulation synchronisation protocols developed to increase the proportion of normal synchronous ovulations. Experiment 1 characterised the growth of the ovulatory follicle in heifers (n=19) treated with an intravaginal progesterone releasing device (IPRD) and oestradiol benzoate (ODB), to determine the optimal time to induce ovulation. Using the findings from Experiment 1, Experiment 2 investigated the effect of reducing the duration of IPRD insertion and increasing the interval from IPRD removal to ODB treatment (modified protocol 1 - OPO-6; n=20), and omitting ODB treatment at the time of IPRD insertion (modified protocol 2 - PO-6; n=20). An IPRD (0.78 g progesterone) was inserted at Day 0 (OPO-8) or Day 2 (OPO-6 and PO-6) and all heifers also received 1 mg ODB i.m. Day 8: IPRD removed + 500 μg cloprostenol i.m. At 24 h (OPO-8) and 36 h (OPO-6 and PO-6) post IPRD removal: 1 mg ODB i.m. Fixed-time AI (FTAI) occurred at 54 h for OPO-8 and 72 h for OPO-6 and PO-6, post IPRD removal. After IPRD treatment all OPO-6 and OPO-8 heifers initiated a new follicular wave whereas 25% of PO-6 heifers failed. Diameter of the dominant follicle was larger at FTAI in the PO-6 (11.34 ± 0.50 mm) compared to the OPO-8 protocol (9.74 ± 0.51 mm; P<0.05), but similar to the OPO-6 protocol (10.52 ± 0.51 mm). Proportion of ovulations occurring 12 h prior and 24 h post FTAI was similar for the PO-6 (80%) and OPO-6 (75%) protocols but numerically lower in the OPO-8 heifers (60%). The apparent improvement in ovarian response in heifers treated with the modified protocols needs to be confirmed in larger field studies. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

    Effective HIV prevention requires efficient delivery of safe and efficacious drugs and optimization of user adherence. The user's experiences with the drug, delivery system, and use parameters are critical to product acceptability and adherence. Prevention product developers have the opportunity to directly control a drug delivery system and its impact on acceptability and adherence, as well as product efficacy. Involvement of potential users during preclinical design and development can facilitate this process. We embedded a mixed methods user evaluation study into a safety and pharmacokinetics (PK) trial of a pod-intravaginal ring delivering antiretroviral agents. Women enrolled in two cohorts, ultimately evaluating the safety/PK of a pod-IVRs delivering TDF-alone, TDF-FTC, and/or TDF-FTC-MVC. A 7-day use period was targeted for each pod-IVR, regardless of drug or drug combination. During the clinical study, participants provided both quantitative (i.e., survey) and qualitative (i.e., in-depth interview) data capturing acceptability, perceptibility, and adherence behaviors. Initial sexual and reproductive health history surveys, daily diaries, a final acceptability and willingness to use survey, and a qualitative in-depth interview comprised the user evaluation data for each pod-IVR experienced by the participants. Overall, the majority of participants (N = 10) reported being willing to use the pod-IVR platform for HIV prevention should it advance to market. Confidence to use the pod-IVR (e.g., insertion, removal) was high. There were no differences noted in the user experience of the pod-IVR platform; that is, whether the ring delivered TDF-alone, TDF-FTC, or TDF-FTC-MVC, users' experiences of the ring were similar and acceptable. Participants did report specific experiences, both sensory and behavioral, that impacted their use behaviors with respect to the ring, and which could ultimately impact acceptability and adherence. These experiences, and user

    This experiment aimed to compare circulating progesterone (P4), follicular dynamics, and fertility during reuse of intravaginal P4 implants that were sanitized by autoclave or chemical disinfection in lactating Holstein cows submitted to fixed-time artificial insemination (FTAI). For this, 123 primiparous and 226 multiparous cows from 2 farms, averaging (mean ± standard deviation) 163.9 ± 141.9 d in milk, 35.7 ± 11.3 kg of milk/d, and a body condition score of 2.9 ± 0.5, were enrolled in the study. Cows were randomly assigned to 1 of 2 treatments using a completely randomized design and each cow received a reused implant (1.9 g of P4; previously used for 8 d) that was either autoclaved (AUT; n = 177) or chemically disinfected (CHEM; n = 172) on d -10. Also on d -10, cows received 2 mg of estradiol benzoate and 100 μg of GnRH. On d -3, cows received 25 mg of dinoprost (PGF 2α ). A second PGF 2α was given on d -2, along with 1 mg of estradiol cypionate and P4 implant removal. Cows received FTAI on d 0. A subset of cows (n = 143) was evaluated by ultrasound on d -10, -8, -6, -3, -2, 0, and 5 to identify ovarian structures, and blood was sampled on d -10, -3, and -2 for P4 concentrations by RIA. Pregnancy diagnoses were performed at d 32 and 60. Statistical analyses was performed using PROC-MIXED for continuous variables and PROC-GLIMMIX of SAS 9.4 (SAS Institute Inc., Cary, NC) for binomial variables. The treatments did not differ in circulating P4 on d -10 or -3, but P4 was greater on d -2 in CHEM cows. Ovulation to the treatments on d -10 was associated with lower circulating P4 on d -10 (2.0 vs. 3.1 ng/mL) and resulted in greater P4 on d -3 (4.0 vs. 2.4 ng/mL) and more cows with a corpus luteum on d -3 (100 vs. 40%) than nonovulating cows. Cows that ovulated to d -10 treatments were more likely to have a synchronized new follicular wave (97.9 vs. 63.2%) and had an earlier wave emergence (1.9 vs. 2.6 d), resulting in less cows ovulating a persistent follicle

Para ello, se hará hincapié en tres dimensiones. La primera, consiste en el análisis de los emergentes de la mencionada Carrera a la luz de las legislaciones, y regulaciones que promueven Derechos Sexuales como parte fundamental de los derechos humanos (DDHH. La segunda estriba en el análisis de tales emergentes en relación a discontinuidades y rupturas con lo que se definirá como Modelo Médico Hegemónico (MMH. Por último, se indagará en las políticas, representaciones y prácticas respecto al misoprostol. Esta investigación es de carácter cualitativo. El corpus analizado consiste en entrevistas semi-estructuradas a 24 estudiantes de la mencionada carrera y en regulaciones vigentes emitidas tanto por organismos médicos nacionales, latinoamericanos e internacionales. Como resultados preliminares, primero, se destacan la escasa permeabilidad en la carrera de las regulaciones vigentes, los conocimientos y actualizaciones farmacológicas expresadas en los documentos emitidos por organismos médicos nacionales, latinoamericanos e internacionales en los últimos 10 años. En segundo lugar, resalta la predominancia de un silencio o vacío en el currículo en relación al aborto. Este silencio no es inocuo, sino que tiene efectos concretos: no garantizar el cumplimiento con el marco de DDHH vigentes en Argentina. Por último, el desconocimiento sobre el misoprostol y su amplia utilidad en el campo gineco-obstétrico refuerza la asimetría en la relación médico/a-paciente y una idea de aborto medicalizado que, por lo tanto, robustece al MMH.

    Effective interaction between mucoadhesive drug delivery systems and mucin is the basis of effective local placement of drugs to play its therapeutic role after mucosal administration including vaginal use, which especially requires prolonged drug presence for the treatment of gynecological infectious diseases. Our previous report on phenylboronic acid-rich nanoparticles (PBNPs) demonstrated their strong interaction with mucin and mucin-sensitive release profiles of the model protein therapeutics interferon (IFN) in vitro, but their poor stability and obvious tendency to aggregate over time severely limited future application. In this study, sulfonate-modified PBNPs (PBNP-S) were designed as a stable mucoadhesive drug delivery system where the negative charges conferred by sulfonate groups prevented aggregation of nanoparticles and the phenylboronic acid groups ensured effective interaction with mucin over a wide pH range. Results suggested that PBNP-S were of spherical morphology with narrow size distribution (123.5 nm, polydispersity index 0.050), good stability over a wide pH range and 3-month storage and considerable in vitro mucoadhesion capability at vaginal pH as shown by mucin adsorption determination. IFN could be loaded to PBNP-S by physical adsorption with high encapsulation efficiency and released in a mucin-dependent manner in vitro. In vivo near-infrared fluorescent whole animal imaging and quantitative vaginal lavage followed by enzyme-linked immunosorbent assay (ELISA) assay of IFN demonstrated that PBNP-S could stay in the vagina and maintain intravaginal IFN level for much longer time than IFN solution (24 hours vs several hours) without obvious histological irritation to vaginal mucosa after vaginal administration to mice. In summary, good stability, easy loading and controllable release of protein therapeutics, in vitro and in vivo mucoadhesive properties and local safety of PBNP-S suggested it as a promising nanoscale mucoadhesive drug delivery

    Full Text Available El complejo suspensorio del hombro es una estructura sumamente importante, compuesta por un anillo de huesos y tejidos blandos. Las lesiones aisladas de este complejo anatómico son frecuentes y no afectan su estabilidad. La interrupción doble conduce a la inestabilidad de esta estructura y usualmente requiere tratamiento quirúrgico. La triple interrupción, por su parte, es sumamente rara y es encontrada en casos de trauma de alta energía a menudo en asociación con otras lesiones. Se presenta una triple lesión del complejo suspensorio del hombro en un paciente de 46 años de edad, con una fractura de la glenoides, del acromion tipo III de Kuhn y de la coracoides tipo II de Ogawa. En este caso, la fractura del acromion fue tratada con fijación percutánea con alambres de Kirschner, por tener asociado lesiones de partes blandas que contraindicaron la reducción abierta. La fractura de la glenoides y de la apófisis coracoides fueron tratadas conservadoramente. Después de 6 meses de evolución, el paciente tuvo un resultado funcional aceptable, con una abducción de 90 grados, los 30 grados de rotación externa y 70 de rotación interna, además asintomático y consolidación de todas las fracturas. A pesar de ser catalogada de una lesión grave del cinturón escapular y estar asociada a otras lesiones se obtuvo un resultado satisfactorio al final del tratamiento.

    Full Text Available Riassunto - L’Autore ripercorre in chiave critica l’evoluzione delle politiche legislative in materia di lavoro, alla luce dell’attuale fase di crisi economico finanziaria. Nell’esaminare i principali interventi normativi attuati da inizio secolo, l’Autore mette in evidenza le scelte di metodo e gli elementi di continuità che accomunano i vari provvedimenti, individuandoli nell’affannosa ricerca del punto di equilibrio tra flessibilità e garantismo. La riflessione si chiude con alcuni interrogativi sulle ultime linee di riforma del mercato del lavoro e con l’auspicio che, anche al cospetto delle imprescindibili ragioni dell’economia, il diritto del lavoro possa continuare a svolgere il proprio tradizionale ruolo di disciplina di tutela della persona.   Abstract - The author analyzes, with a critically oriented approach, the development of the employment law, in the light of the current economic and financial crisis. In examining the main regulatory measures implemented since the beginning of the century, the author highlights the methodological choices and the elements of continuity that unite the various measures, focusing them in a hard research of a point of balance between flexibility and security. The discussion concludes with some questions about the last lines of the reform of the labor market and with the hope that, even in the face of compelling reasons of economy, labor law can continue to play its traditional role of governing the protection of person.

Estudio desarrollado a sabiendas de la importancia que reviste el sistema electoral como un medio que permite a los ciudadanos convertir su voto expresado en las urnas en escaños a favor de determinado candidato o partido. En dicho análisis tomamos en cuenta la evolución constitucional del sistema electoral mexicano, la participación de las fuerzas minoritarias en la integración del Senado y de la Cámara de Diputados, la división que se hace del territorio en circunscripciones electorales, la barrera electoral que se fija a los partidos políticos para acceder a la representación en el Parlamento, la fórmula de asignación que se aplica a la votación obtenida, para finalmente concluir que el sistema electoral mexicano es esencialmente mayoritario aun cuando se vista de proporcional.

    Full Text Available

    La doctora MarthaLucía Tamayo comparte muchas inquietudes alrededor del Libro del Almismo, el Libro del Pensar; de dónde salió ese nombre; de juntar en medicina y en genética a tres escritores como lo son Jorge Luis Borges, Macedonio Fernández y Julio Cortázar. Su conferencia dice así:

    El término almismo fue ideado por Macedonio Fernández porque defendía mucho el ensimismamiento y el pensamiento hacia el interior, mirar hacia adentro; cada uno somos un “sí mismo” que nos hace diferentes aunque al mismo tiempo podemos ser iguales. Todos tenemos esa parte interior que la medicina debe trabajar y que no puede olvidar.

    “El Libro del Almismo, el libro del pensar” nos lleva a replantear y a repensar un poco la medicina que queremos, una medicina vuelta a pensar.

    Quiero contarles la historia de cómo se llegó a este libro y por qué y para qué se sigue trabajando en estos temas: Después de mi internado y de un trabajo un poco triste de rural, volví al Instituto de Genética y a la Universidad Javeriana en donde encontré al doctor Bernal y un espacio que estaba buscando para esa medicina diferente que quería, con un grupo de personas que me permitía no sólo ver la medicina sino ver muchas otras cosas más; había espacio para la literatura, para Mafalda, para hablar de niños, de locos, había incluso tiempo para hablar de medicina dentro del golf, de carros antiguos y de todo eso fui aprendiendo.

    Eso era lo que estaba buscando. Una medicina que diera espacios diferentes, que fuera más humanizada. Rápidamente me ubiqué y me quedé! No me arrepiento en lo absoluto de haberme quedado porque fue, ha sido y sigue siendo, una experiencia enriquecedora, de muchas vivencias importantes. Sabía exactamente dónde estaba y sabía que había que seguir rápido y había que trabajar muchos aspectos de esa medicina que estábamos buscando y de esa genética especial.

Se examina la competitividad del Valle en relación con Colombia y con el resto del mundo. Se cuestiona la insistencia en una estrategia exportadora como dinamizadora del desarrollo económico. Se identifica que una gran parte de la población está excluida de los beneficios del desarrollo económico. Para construir un modelo de desarrollo que incluya a esta población se recomienda recuperar la senda de la industrialización, invertir en el capital humano (educación de alta calidad, salud, salubridad y nutrición, e invertir en infraestructura. La participación del Estado en estas inversiones sociales es necesaria para disminuir la desigualdad y aumentar el crecimiento económico.

Se utilizó óptica azul, con una red de difracción de 600 lineas/min, obteniéndose una dispersión de 74.2 A/mm y una resolución de 2.5 A, en el rango espectral de 3500 a 6500 A. Seis placas fueron tomadas con emulsión IIa-O y dos con IIa-D. Los tiempos de exposición fueron entre 10 y 150 minutos. El cometa se encontraba entre 0.70 y 1.04 UA del Sol, y entre 1.28 y 0.73 UA de la Tierra. Las emisiones más prominentes en el espectro, son las del CN, C2, y C3. Otras emisiones detectadas corresponden a CH, NH2 y Na. Los espectros muestran un fuerte continuo, indicando un contenido significativo de polvo. Se detectó mayor intensidad del contínuo, en la dirección anti solar, lo cual es evidencia de la cola de polvo.

Para poder gerenciar el cuidado se debe saber administrar.

    Full Text Available A partir de un texto del poeta Octavio Paz llamado «La imagen», se busca proseguir la equivalencia entre las imágenes de la poesía y la función que ellas tienen para el poeta, y el fantasma fundamental y su función para el analizante que está en el momento del pase. Se parte de la idea de que la poesía busca entrar en el ser así como el psicoanálisis tiene como finalidad apuntar al corazón del ser del sujeto. Se hace entonces una distinción del concepto de «ser» para el psicoanálisis, haciendo alusión también al discurso de la filosofía. Esclarecido el sentido de lo que es el «ser» para el psicoanálisis, se aborda de lleno – entre otras cosas, relacionadas con la experiencia del pase específicamente- la equivalencia entre la definición que hace Octavio Paz de «La Imagen» y el momento del pase en el análisis de un sujeto, imagen que, al igual que el mito para la filosofía, las leyes para la ciencia y el matema para el psicoanálisis, se constituyen en los instrumentos con los que cada una de estas disciplinas horadan en lo real.

    1999-01-01

    Costruita con l'intento di presentare le idee oltre ai protagonisti della matematica, questa storia ha il duplice pregio dell'esaustività e della chiarezza. Essa prevede infatti vari livelli di lettura: lo specialista vi trova una messe di dati, fonti e spunti di ricerca, mentre lo studente ha a disposizione un formidabile strumento di consultazione e sintesi. L'arco temporale coperto è vasto: dalla Mesopotamia a Euclide, da Fibonacci all'invenzione del calcolo infinitesimale, da Gauss a Poincare, con un'appendice dedicata agli sviluppi piu recenti scritta appositamente per la prima edizione italiana del 1991, nei «Manuali» Einaudi.

Utilizando un modelo del ciclo de vida con datos de la encuesta de hogares de 1994 y 1995, muestra que el comportamiento del ingreso está afectado principalmente por las características demográficas del hogar y los rasgos socio ocupacionales de sus miembros. El comportamiento del gasto está determinado ante todo por el ingreso y, en menor medida, por las características sociales del hogar y el gasto de otros hogares con características similares. También examina la influencia de la incertidumbre acerca de los ingresos en el gasto de los hogares para comprobar si estos actúan con motivos de precaución.

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    These pictures are divided into six chapters: Background, Components, Springline, Piers, Arch, Centring Erection and Removal, and Trimming.

    A lo largo de la historia, el Arco de fábrica ha sido el componente constructivo más característico de la Arquitectura y la Ingeniería desde que después de sus inicios etruscos en la época romana fuera desarrollado adelantándose con ello a la cultura helénica.
    El Arco, desde entonces, viene empleándose como una solución constructiva eficiente para cubrir espacios con materiales que no soportan tracciones. La originalidad técnica del Arco lo ha llevado a imponerse como símbolo de las hazañas bélicas como era el Arco de Triunfo.
    En el cambio de siglo y milenio en el que nos encontramos, un salto técnico fundamental se desvela en este Congreso, el Sistema de Albañilería Integral, que abre la posibilidad de ampliar el campo de aplicación de la albañilería con la incorporación del acero, a través de las perforaciones de las piezas, lográndose por fin armar en las tres direcciones del espacio cualquier muro de fábrica que se desee.
    El Arco del Milenio conmemoró el 12th IBMAC de Madrid, mostrando en él los avances técnicos que el Sistema de Albañilería Integral permite, al tratarse de un arco inclinado en el espacio y, por tanto, el primer arco de fábrica construido fuera de la vertical, mediante fábrica de Ladriflor aparejada a tizón, reforzada con barras y cercos.

Prueba de ello es la ratificación por parte del gobierno colombiano en el año 2007, del Convenio 182 de la OIT sobre la Prohibición de las Peores Formas de Trabajo Infantil y la Acción Inmediata para su Eliminación. En el plano regional, como parte del Plan de Desarrollo del Departamento del Valle del Cauca 2008-2011, se está implementando actualmente una estrategia territorial de erradicación del trabajo infantil en sus 42 municipios. Considerando este panorama, este trabajo indaga cuáles son los determinantes del trabajo infantil y la escolaridad en el departamento del Valle a partir de los datos de la Encuesta Nacional de Calidad de Vida del año 2003. Para el análisis se emplea un modelo econométrico Probit Bivariado, que permite el estudio conjunto e interrelacionado de decisiones diferentes, en este caso la asistencia escolar y el trabajo.

El uso del examen de orina completa y de urocultivo debe ser racional. La bacteriuria asintomática no debe ser buscada ni tratada, en parte porque esto favorece el desarrollo de bacterias resistentes a antibióticos. Distintos cuadros clínicos requieren de distintas duraciones de terapia antibiótica, y tanto el exceso de días de tratamiento como su falta deben evitarse. Se requiere investigación en la búsqueda de estrategias más efectivas para prevenir las ITU recurrentes y en el desarrollo de nuevos antibióticos orales para las ITU resistentes.

El dios Apolo, de naturaleza ilimitada, insondable, caprichosa, plantea al hombre enigmas que lo enfrentan con el sufrimiento y con la muerte. Allí, Edipo se confronta con enigmas enviados por el dios en los que se pone en juego su propia existencia. Tiempo después, en el transcurrir del siglo XX, reaparece una nueva forma de este dios arbitrario y arrogante: el desaparecedor de personas, ese inmoderado que impone moderación, borra con su acto un cuerpo, una imagen, un nombre, y formula un nuevo enigma siniestro que enfrenta otra vez al hombre con el dolor y con la muerte.

    Full Text Available INTRODUCCIÓN: Los Desórdenes por Deficiencia de Yodo son un problema serio de salud pública, con cerca de 2 mil millones de personas a riesgo de padecerlos, pudiendo causar bocio neonatal, cretinismo, retardo mental, hipotiroidismo, entre otros. Estos desórdenes son aún prevalentes, y en algunos casos los esfuerzos para su erradicación se han traducido en aumento del riesgo de exceso poblacional de yodo y autoinmunidad tiroidea. En Colombia, se desconoce el estado real de yodo en la población. OBJETIVOS: Determinar la mediana de la yoduría en población escolar, y de los hábitos del consumo de sal, función y parámetros de autoinmunidad tiroidea, y cociente intelectual. MATERIALES Y MÉTODOS: Estudio basado en la comunidad, de corte transversal. Se evaluaron las variables sociodemográficas, la frecuencia de bocio y los niveles de TSH, anti-TPO, anti-Tg, anti-TSHR, yoduria, test de factor G de Cattell, y hábitos del consumo de sal. RESULTADOS: El consumo de sal promedio persona/día fue de 18,13 g. El 37,9% presentó bocio. 36,1% tenían un valor límite en el cociente intelectual. La mediana de yoduria fue de 510,3 μg/L. El 42,75% tuvo anti-TPO positivos, y el 2,87% anti-Tg positivos. El 10% presentó niveles de TSH elevados. CONCLUSIÓN: En escolares de zona urbana, hay un exceso en la mediana de yoduria, pudiendo explicarse por el alto consumo de sal. La alta prevalencia de autoinmunidad tiroidea y bocio, junto al alto nivel de la TSH, puede ser consecuencia del exceso en la ingesta de sal y de otros factores medioambientales/ hereditarios.

Era un poporo quimbaya, pieza maestra de la orfebrería prehispánica. Un objeto bello bello que levanta su bruñido vientre globular y su cuello coronado por cuatro cuerpos esféricos sobre una exquisita base de filigrana fundida, y parece flotar en un espacio propio. Quien lo contempla no puede menos que asombrarse, deleitarse y sentir admiración por sus artífices. Detrás de la compra del poporo había una clara preocupación oficial por proteger una riqueza que comenzaba a entenderse como parte del patrimonio nacional. Esta motivación se pone de manifiesto en una serie de documentos relativos a su adquisición.

    Full Text Available In this article, the evolution of the different systems of transporting and storing submarine oil and its by-products (petroleum gas and natural gas, is dealt with stressing the importance of the use of concrete boats. Due to the high cost of oil pipelines, we have passed from tanks built on land to prestressed concrete tanks which can be berthed at great depths or anchored to the bottom to keep them afloat, it being possible to unmoor them for transferring them. Transporting and storing liquated gas leads US to see the advantages of prestressed concrete over steel, as the latter becomes brittle at low temperatures, whereas the former's strength increases. The different forms and possible sections are analyzed, stressing the great importance of the solution of the double concrete hull with pearlite insulation. Finally, a study is made of «light concretes », not the classical types used as thermal and acoustic insulation, but the semi-heavy ones made with expanded clay, high quality sand and P-450 cement, which technique is not yet as developed in Spain at might be wished.En este artículo se trata la evolución de los distintos sistemas de transporte y almacenamiento del petróleo submarino y sus derivados (gas de petróleo y gas natural, resaltando la importancia del uso de barcos de hormigón. Debido al gran coste de los oleoductos, se ha pasado de los tanques construidos en tierra firme a los depósitos de hormigón pretensado que pueden estar fondeados a gran profundidad o anclados al fondo para mantenerlos flotantes, existiendo la posibilidad de poder desamarrarlos para su traslado. El transporte y almacenamiento del gas licuado nos hace ver las ventajas del hormigón pretensado sobre el acero, pues éste se vuelve quebradizo a bajas temperaturas, mientras aquél aumenta su resistencia.

    2000-01-01

    Full Text Available En el presente trabajo se estudia un ámbito que normalmente se esquiva y se enmascara: Las prácticas racistas. Esta evasión del tema se da en diferentes planos discursivos, y es una práctica, cada vez más frecuente en América Latina, pues aquí se hace de la integración étnica uno de los ejes centrales de la construcción de sus relaciones identitarias y políticas. Se propone, entonces, este trabajo develar la naturaleza y el movimiento de prácticas racistas presentes no sólo discursivamente, en la práctica política, en la práctica laboral, sino que también están presente en nuestra vida cotidiana, bajo nuevas formas y contenidos que se distancian del racismo tradicional e incorpora una nueva gramática racista, una suerte de racismo moderno, no basado en el fenotipo o características físicas como elemento central, sino en un racismo basado en la diferencia cultural, lo cual plantea un plano más excluyente, pues en este planteamiento el “objeto de racismo” no es un objeto de racismo limitado, como en el racismo tradicional, en el cual siempre es utilizado por quien practica el racismo; en el racismo contemporáneo se pretende una ruptura completa y una exclusión total del otro.

  2. Etiche del paesaggio

    Directory of Open Access Journals (Sweden)

    Massimo Venturi Ferriolo

    2015-11-01

    Full Text Available L’etica riflette sui rapporti fra uomo e ambiente. Indaga l’azione dell’uomo. Svela la sua visione della vita e il mondo possibile e accoglie in sé un complesso di norme morali e di costume che identificano un preciso comportamento nella vita di relazione. Si riferisce all’agire dell’individuo in una struttura sociale che lo comprende. Siamo alla ricerca di un’essenza del paesaggio indipendente dalla mera pittura, dalla rappresentazione, dall’immagine sentimentale: dalla natura sia ideale che reale. Prendere coscienza della cosa in sé, anche nei suoi aspetti ideali, significa comprenderne la complessità. Possiamo leggere quindi ogni paesaggio come realtà etica, risultato dell'operosità dell'uomo nella natura, ambito complessivo della vita: nel significato peculiare di progetto del mondo umano, che parte da lontano, da quando l'uomo ha incominciato a trasformare il proprio ambiente naturale per creare i luoghi dell'abitare, modellati con la mano e con lo spirito. La conoscenza dei paesaggi in tutta la loro complessità, a partire dal mondo antico, diventa quindi un nostro obiettivo. Questo significa superare, se non addirittura rovesciare, alcuni luoghi comuni consolidati e storicizzati: la teoria secondo la quale il paesaggio, nella sua dimensione estetica, sarebbe un'invenzione della modernità; il collegamento tra la moderna pittura di paesaggio e la nascita dei concetti estetici; la confusione tra natura e paesaggio, frequente nelle concezioni ecologico- ambientaliste; la tesi lessicale della nascita della coscienza del paesaggio, legata all'esistenza di una parola specifica che lo indichi.

No es aventurado decir que en la propuesta viquiana la actividad propia de la tópica, ligada al uso del lenguaje, la retórica y la elocuencia, se acerca más aquello que von Wright ubica dentro del "paradigma comprensivo"; mientras que la crítica, identificada con el método cartesiano, privilegia la abstracción, la deducción lógica y el análisis matemático; es decir, todo aquello ligado al conocimiento de la naturaleza. La gran diferencia en tre tópica y crítica radica, al final, en el criterio de verdad propio de cada perspectiva: mientras la crítica encuentra la verdad en la exterioridad del mundo natural, en algo que los hombres no hacen; en cambio, la única forma de verdad en el terreno de la tópica es como "verdad hecha" o "verum factum"; es decir, la verdad que nosotros mismos hacemos como agentes históricos, lingüísticos, creadores de cultura, de vida política y social.

    Full Text Available Este artículo discute cómo las prácticas de salud dirigidas a las mujeres construyen determinadas significaciones sobre la salud y el cuerpo femenino, comprendiendo que las prácticas en salud producen determinadas formas de ser, vivir y sentir, y constituyen modos de ser mujer y de ser hombre. Se presentan los datos de una investigación desarrollada en un servicio académico de salud, con mujeres que se realizaron exámenes de prevención de cáncer de útero y mama, entre mayo y diciembre del 2002. La recolección de datos se realizó mediante observaciones de las prácticas de la salud y entrevistas con las usuarias del servicio. En términos teóricos, el punto de referencia fueron los estudios feministas, especialmente autores(as cuyas teorizaciones son postestructuralistas. Se espera que este estudio contribuya con la reflexión sobre las prácticas de salud dirigidas a las mujeres, posibilitando una ampliación sobre lo que se entiende por femenino y, dando espacio a otras formas de ser y de estar en el mundo, además de aquellas que el discurso hegemónico sobre mujeres propone como adecuadas.

Por esto el gerente líder del siglo XXI se debe formar, capacitar, entrenar en aquellas habilidades-competencias requeridas por este nuevo entorno.

    Full Text Available El manejo terapéutico del paciente con artrosis tiene como objetivo disminuir la sintomatología dolorosa e inflamatoria, mejorar la capacidad funcional del paciente y la aplicación de intervenciones terapéuticas eficaces y lo más seguras posibles. Un enfoque centrado en el paciente implica su participación activa en el diseño del plan terapéutico y en la toma de decisiones informadas oportunas en todas las etapas de la enfermedad. La educación terapéutica, la actividad física y el ejercicio terapéutico junto con el control de peso, en caso de sobrepeso u obesidad, constituyen el núcleo central del tratamiento. Los autocuidados individuales y por los familiares son fundamentales en el control del día a día del paciente. El uso de terapias físicas, ayudas técnicas (bastón, etc. y de fármacos tipo analgésicos simples, opioides y antiinflamatorios tiene evidencias demostradas en el control del dolor, mejora la funcionalidad y la calidad de vida del paciente y una clara recomendación de uso en el tratamiento de la artrosis.

Se utilizó la escala de Likert con tres (3 alternativas de respuesta. La investigación es de tipo descriptiva y aplicada, bajo diseño no experimental de tipo transeccional descriptiva y de campo. La población quedó conformada por los usuarios de las líneas de taxis del municipio Maracaibo. Se aplicó muestreo aleatorio por conglomerado. La confiabilidad del instrumento se midió a través del coeficiente alfa de Cronbach resultando de 0,82 lo cual se considera aceptable. Los resultados revelan que la calidad del servicio de taxis del municipio Maracaibo es mediana por lo tanto este servicio es susceptible a mejoras, las cuales son necesarias para elevar la calidad de vida de los marabinos. Este resultado se obtuvo con el instrumento originalmente adaptado de 32 ítems y con el cuestionario resultante del análisis factorial, de 24 ítems; esto confirma lo apropiado de esta técnica, ya que se redujo el número de ítems y de las dimensiones originalmente adaptadas y no se encontraron diferencias significativas en los resultados con ambos instrumentos; de esta manera se puede medir la calidad del servicio de taxis en el municipio Maracaibo a través de las dimensiones: confiabilidad del servicio, socialización y responsabilidad.

Así, mientras la caída de la fecundidad y la estabilización de las tasas de mortalidad han contribuido a un progresivo retroceso de la vitalidad natural, la masiva emigración de antaño ha dado paso al papel de Andalucía como incipiente foco de inmigración y al creciente protagonismo de movimientos internos de relocalización de la población. Desde el punto de vista territorial estas afirmaciones quedan matizadas por los notables contrastes que se producen entre los distintos ámbitos que conforman la región y que contraponen al medio rural con el urbano, al litoral con el interior o a las grandes ciudades con sus periferias.

    Jesús Lucas Martín Espejo

    Full Text Available Introducción: Valorar si el descanso peritoneal, de al menos un día semanal, ha supuesto mejoras en la rehabilitación de los pacientes y el impacto clínico que puede suponer. Nos planteamos además cuantificar el beneficio económico. Material y Método: Se realizó un estudio longitudinal, retrospectivo, descriptivo. De los pacientes atendidos en nuestra unidad desde el 1 de enero de 2014 al 31 de diciembre de 2014, se estudiaron los pacientes que cumplieran todo el año de seguimiento y que no procedieran de otras técnicas de depuración como la hemodiálisis o trasplante renal. La muestra de estudio estuvo compuesta por 40 pacientes, de los que 21 tuvieron prescrito al menos 1 día semanal de descanso peritoneal y 19 pacientes sin descanso. Se recogieron las siguientes variables al inicio del periodo de estudio y a los 12 meses: Variables demográficas, variables relacionadas con el estado de volumen, datos clínicos relacionados con la técnica, se pasó una encuesta de satisfacción a todos los pacientes estudiados, y se recogieron los importes del coste mensual de cada tipo de tratamiento. Resultados: Las diferencias iniciales entre los grupos, eran esperables ya que son los valores en los cuales se ha basado la prescripción del día de descanso. La exposición a la glucosa, al comienzo y al final fue menor en el grupo con descanso. Al año, no se encontró diferencias en los parámetros estudiados. Una encuesta de satisfacción nos reveló a que dedican los pacientes el día de descanso y los que no lo tienen a que lo dedicarían. Conclusiones: El descanso peritoneal no ha supuesto una peor evolución de los parámetros clínicos estudiados al año de seguimiento, cumpliendo las recomendaciones de adecuación de diálisis de las guías clínicas. La exposición a la glucosa, aun sin llegar a ser significativa por la duración del estudio, ha sido menor en el grupo con descanso. El día de descanso ha facilitado a los pacientes

    Semprún, Jorge

    2011-06-01

    Full Text Available In May 2003 the twelfth edition of the «Aranguren Conferences» was held. Jorge Semprún gave three keynote speeches titled «Kant and the Maquis’ rucksack», «The radical evil and the Buchenwald latrines» and «Literature and memory of the evil: from Sartre to Paul Ricoeur», all of them grouped under the generic denomination Memory of Evil. The thread running through the three speeches was Semprún’s experience as a political deportee at Buchenwald concentration camp, so close to the Weimar camp of Schiller and Goethe. There, he could experience the radical evil, but also the brotherhood through the antifascist resistance groups who coordinated the various clandestine political groups at the camp. This experience helped him review some of the philosophical readings he had done as a philosphy student at the Sorbonne, as well as those readings he took an interest in following the end of the war. In this way, Semprún went over various authors (Immanuel Kant, André Malraux, Edmund Husserl, Jacques Maritain, Martin Heidegger, Karl Marx, Hannah Arendt, Jean Paul Sartre, Paul Ricoeur or Primo Levi arguing their relationship with the issue of Evil.

    En mayo de 2003 se celebró la duodécima edición de las «Conferencias Aranguren». Jorge Semprún dictó tres conferencias magistrales tituladas «Kant y la mochila del maquis», «El mal radical y las letrinas de Buchenwald» y «Literatura y memoria del mal: de Sartre a Paul Ricoeur», agrupadas todas ellas bajo el título genérico de Memoria del mal. El hilo conductor de las tres intervenciones fue la experiencia de Semprún como deportado político en el campo de concentración de Buchenwald, tan cercano al Weimar de Schiller y Goethe. Allí pudo experimentar el mal radical, pero también la fraternidad, a través de los grupos de resistencia antifascista que coordinaban en el campo los distintos grupos políticos clandestinos. Esta experiencia le sirvió para repasar las lecturas

    Full Text Available ¿Qué soluciones políticas podemos encontrar para las nuevas formas de subjetividad? ¿Cómo debe la teoría feminista interpretar la voluntad de romper los límites y, al mismo tiempo, la necesidad de normalidad? Los pensadores posmodernos son escépticos respecto de las nociones tradicionales de identidad; los límites que definen al sujeto no sólo construyen sino que también excluyen. Debemos oponernos a las interpretaciones dominantes de normalidad y aceptar otras posibles alternativas a los modelos tradicionales. Necesitamos ir más allá del binario sistema sexo/género y de la orientación sexual y mantener una mentalidad abierta, persiguiendo una filosofía de la libertad.

    Full Text Available La investigación sobre los procesos de producción sonora en la crea-ción de obras audiovisuales afectan, en términos generales, a cuestio-nes exclusivamente tecnológicas. Para valorar su rendimiento expresi-vo en la construcción del discurso es imprescindible que, de forma paralela, esta investigación se aborde también desde la perspectiva de la realización audiovisual.Para ello es necesario asumir que los conceptos básicos en los que se fundamenta el desarrollo tecnológico no han de ser necesariamente esenciales en los estudios que se plantean desde puntos de vista creati-vos.En particular es oportuno someter a examen el concepto de fidelidad y reivindicar las posibilidades emotivas, e incluso significantes, de formatos de producción sonora hoy en desuso.

    The old age is been surrounded bymisteries, myths and prejuidices. The concepts and the valoration of the ancient man, have been contradictory. In different places and in many cultural moments, the old man has been taken from the glory to the scorn. The actual world scrolls the ancient in a very fast rhythm; the social changes have generayed conditions of disadvantajes for that group of the population, difficulting even more the process of growing old, that in fact has a lot of limitations. Its important that a lot of professionals from many institutions involved with this important cause, join the work developed by geriatrics and gerontologics;  soin this way we can restore the social values of the ancient, who deserves a peacefull old age in compensation with his participation in the job of building a better society. Only in this way, the fear to grow old will be lost.

    La vejez se ha visto rodeada de tabúes, mitos y prejuicios. Han sido contradictorios los conceptos y la valoración del anciano, quien en lugares y momentos culturales ha estado desde ensalzado hasta despreciado. El mundo actual, desplaza al geronte a ritmo acelerado; los cambios sociales han generado condiciones de marginalidad para ese sector de población, dificultando aun más el proceso de envejecer, que de hecho tiene limitaciones. Es por eso importante que al trabajo que desarrollan geriatras y gerontólogos se sumen otros profesionales y un sinnúmero de entidades; en aras de eliminar prejuicios y rescatar el valor social del anciano, quien por su legado merece un ocaso, que compense su aporte y participación en la construcción de la sociedad, solo así se perderá el miedo a envejecer.

    Señoras y señores:

    Estoy profundamente conmovido y emocionado, al escuchar los elogiosos comentarios de quienes me precedieron en el uso de la palabra, pues, aunque inmerecidos, naturalmente me enorgullecen sobremanera.

    Quiero, antes de iniciar mi discurso, agradecer a la noble Academia de la Lengua, a su presidente doctor Jaime Posada y a los miembros de su Junta Directiva, la generosa hospitalidad en este precioso auditorio que contribuye a dar realce a esta sesión solemne.

    Muchas Gracias.

    Deseo manifestar, que los conceptos que vaya emitir, reflejan mi pensamiento y por tanto, de ellos soy responsable. No pretendo con ellos criticar, ni mucho menos ofender, a personas o instituciones, son más que todo reflexiones, que me llevan a propuestas de trabajo para el futuro y espero que así sean percibidas y analizadas por esta distinguida audiencia.

    El día 3 de enero de 1873, el joven médico Abraham Aparicio, reunió en su residencia, en las primeras horas de la fría noche santafereña, a sus colegas Manuel Plata Azuero, Nicolás Osario, Liborio Zerda, Leoncio Barreta y Evaristo García, con el propósito de crear una sociedad científica, para el estudio y adelanto de las ciencias médicas y naturales, así como para solidarizar al cuerpo médico y darle unidad al ejercicio profesional en el país. Así nació la Sociedad de Medicina y Ciencias Naturales que posteriormente sería elevada a la categoría de Academia Nacional de Medicina, por la Ley 71 de 22 de noviembre de 1890.

    Sin embargo, bien vale la pena rememorar los orígenes aún más remotos, de esta insigne institución.

Ahora el cibernauta puede acceder a una inimaginable oferta de información multimedia. Este caos garantiza libertades, pero presenta enormes limitaciones para quienes no tienen acceso a la tecnología, particularmente en países de América Latina, carentes de Políticas de Comunicación que generen condiciones para un uso intensivo, extensivo y democrático de la ciberred. En el tema “La televisión por cable" relacionado con la cultura visual, multimediática, satelital, informática, televisionada, se señala que tiene como soporte a la más antigua nueva tecnología, la televisión por cable. Se trata de uno de los más grandes negocios disputados por los magnates nacionales y transnacionales de la comunicación que atraparon para el año 2000 a más de 20 millones de suscriptores de la televisión pagada.

Se cuestiona sobre el por qué no aplicar las relaciones públicas, en organizaciones populares, para que mejoren su publicación y orienten sus propósitos de desarrollo. El tema que aborda las Políticas culturales en América Latina acopia un extracto de lo más trascendente de los ensayos del libro editado por Néstor García Canclini. Sobre la telenovela se afirma que esta ha llegado a ser uno de los instrumentos más importantes de la comunicación popular: por ella desfilan las identidades de las más variadas culturas brasileñas. Y en cuanto a la caricatura se relata lo que ocurrió en el Seminario taller " Caricatura y Periodismo", realizado el(9-11 de Nov.- 1987 en el CIESPAL. El estudio sobre el mercado del vídeo se ve dificultado por la imprecisión de los datos obtenidos.

    Full Text Available To broach the goals of development implies broaching the problem of economic growth in a critical manner. Not only the concept of growth but also the means of achieving it in practice should be questioned. Growth is not an end, it is a means of gaining access to development And development should not be understood as a goal, but as a permanent process of learning tending towards more control over the environment and greater levels of well-being. It is not a matter of increasing GNP linearly; development must occur, sustained growth that, without being a threat to mm or to our natural resources, can lead to the eradication of absolute and relati.ve poverty. The low rates of growth of the developing countries constitute structural problem that can /lot be reso1.ved by resorting to the neo-classical mechanisms of mobility, nor to the Keynesian formulas. These have served as a source of inspiration to the Harrod-lX:m3r·type models of growth which limit themselves to stimulating savings and ending unemployment by concentrating exclusively on the monetary demand. Getting OUt of the vicious circle of low growth implies eradicating poverty with respect into the immediateness of a direct attack on the problem. with respect to the developed counties, growth is starting to became harmful, and, given the prevalence of ostensible consumption and of pecuniary emulation, it is imperative to foment non-economic motivation that will permit the eradication of relative poverty.

    Full Text Available Con eje en los diferentes aspectos que adopta el actual proceso de mundialización de la lógica del mercado y expansión capitalista, aún en países socialistas, el presente artículo plantea la necesidad de una reflexión antropológica susceptible de articular el surgimiento de nuevas formas de dominación y representación simbólicas. Se discute el aparente efecto de unificación intelectual producido por la hegemonía del mercado respecto de hechos sociales heterogéneos dados en la historia reciente de las sociedades contemporáneas. Así, la renovada atracción que ejercen los nuevos escenarios sociales reconfigurados en virtud de las modalidades específicas de encarnación y operación de los procesos globalizantes, llama al estudio antropológico de las coyunturas. La autora despliega una interpretación del socialismo de mercado, conjunción -siempre en tensión- de un monopolio político estatal y una liberalización del mercado económico. En esta perspectiva se reubica el interés de una antropología del presente en relevar localmente, en este caso en Vietnam del Norte, la conformación de un nuevo mercado de demandas simbólicas, donde la reaparición de las prácticas culturales de comunicación con los antepasados expresa la necesidad de reunificación familiar y reconciliación con los muertos en la "larga guerra".Tendo como eixo os aspectos diferentes que adota o processo atual de mundialização da lógica do mercado e de expansão capitalista, até mesmo nos países socialistas, este artigo propoe a necessidade de uma reflexão antropológica capaz de articular o aparecimento de novas formas de dominação e de representação simbólica. Discute-se o efeito de superfície de unificação intelectual causado pela hegemonia do mercado em fatos sociais diversos em sociedades contemporâneas.

El panorama contemporáneo nos ofrece dos soluciones al respecto: por una parte, se sostiene que la legitimación del derecho penal emana de la Constitución, y se prescinde de una construcción sistémica del delito en aras de la obtención de consecuencias acordes con lo planteado en la Carta Política. Por otra, desde una propuesta -de corte normativista- se entiende que la legitimación del derecho penal debe encontrarse en la sociedad, y a partir del entendimiento de ésta se encuentra la necesidad de aquél, lo cual ejerce una influencia en la construcción del sistema del delito.

El Entrenamiento Funcional (EF es recomendable para optimizar el control postural del core, mejorando el balance y la ejecución de actividades de la vida diaria.  Objetivo: Revisar la definición, elementos constitutivos, características e implicaciones del EF del core en el movimiento corporal humano (MCH y la salud desde la perspectiva del fisioterapeuta. Metodología: Se incluyeron artículos en inglés y español de las bases Pubmed, Scielo y Ebsco; adicionalmente se incluyeron fuentes electrónicas e impresas y libros. Resultados: 56 documentos cumplieron los criterios de inclusión. La definición más adoptada de EF fue entrenar con un propósito buscando obtener un efecto positivo en la aptitud física. Las implicaciones del EF en el MCH, se relacionan con la ganancia y mejoría de la estabilidad. La propuesta de EF enfocada a las actividades de la vida diaria incluye fases que permiten adquirir la estabilidad hasta lograr el desarrollo de movimiento que demanden más agilidad. En la planificación del EF se deben estructurar los procesos a ejecutar considerando el criterio de funcionalidad. Para organizar la sesión del EF, el fisioterapeuta cuenta con tres maneras de planificar la sesión: globales, por hemisferios y por grupos musculares. Conclusión: La fundamentación teórica sobre el EF permite al fisioterapeuta comprender y determinar cómo esta modalidad de intervención repercute de manera positiva sobre el desempeño funcional y calidad de vida de los sujetos.

    La historia de las truchas del Pacífico, pertenecientes al género Oncorhynchus, es una historia muy interesante que se basa en la persistencia y diversificación de sus especies debido, en gran parte, al dinamismo propio que existe en su medio ambiente. Desde el oeste de Norteamérica, extendiéndose hasta el este de Asia, las truchas del Pacífico han experimentado la...

    Full Text Available Yo no tengo nada contra el plagio. Ustedes, como lectores, seguramente tampoco. Bueno, tal vez prejuicios. Es lógico que los tengan con tanto artículo condenándolo. Hasta ahora, que yo sepa, nadie ha escrito para defenderlo. Los que sí tienen algo, parece ser, son los autores. Una minoría al fin y al cabo. Ya sé que hay que respetar el derecho de las minorías, pero el asunto del plagio, como tantos otros, deberíamos examinarlo con más detalle, y preguntarnos, por ejemplo, ¿por qué se molestan tanto los autores cuando les plagian? ¿En nombre de qué?, sería también una buena pregunta. No me irán a decir a estas alturas que en nombre de la comunidad científica. A fin de cuentas el plagio beneficia la difusión de la ciencia. Los autores se molestan en nombre propio. Naturalmente tienen su derecho, no se lo vamos a discutir, pero, ¿no demuestra eso cierto narcisismo impropio de un científico? ¿La ciencia no es de todos?, como suelen decir en otras ocasiones.

  18. La liberazione del tempo

    2003-01-01

    Negli ultimi dieci anni ho lavorato alla descrizione dei fenomeni naturali da parte di osservatori in movimento. E' un problema che molti credono risolto una volta per tutte dalle trasformazioni di Lorentz della teoria della relatività speciale (TRS nel seguito), ma che in realtà era rimasto aperto per una serie di ragioni che esporrò. Sento di dover dire che ho trovato risultati molto importanti, anche se il giudizio finale sul loro valore non può certo essere il mio. Infatti la conclusione di questa ricerca è duplice: una spiegazione dei dati empirici migliore di quella relativistica, e l'eliminazione di quegli aspetti della TRS che fanno a pugni con il buon senso; il tutto grazie alla liberazione del tempo dall'asservimento alle coordinate spaziali cui era stato costretto nello spazio a quattro dimensioni di Minkowski. La faccenda è raccontata con dovizia di particolari in un libro recente [FS]. Nel presente articolo espongo gli aspetti salienti della ricerca lasciando da parte quelli matematici.

Sus objetivos básicos fueron dar a conocer la formulación teórica y la metodología del TO y hacer la transferencia de las estrategias metodológicas vivenciadas a la práctica docente. El estudio se ha planteado desde una óptica cualitativa con el estudio de caso único. Y como resultados más destacables hay que reseñar el interés y la percepción de la utilidad personal y profesional del TO como instrumento de reflexión sobre la acción y generador de clima positivo. El Teatro del Oprimido es una formulación teórica y un método estético cuya teoría y praxis están inspiradas en la Pedagogía del Oprimido de Paulo Freire, utiliza las técnicas dramáticas como un instrumento eficaz para la comprensión y la búsqueda de alternativas a problemas sociales, interpersonales e individuales.

    Full Text Available Nei primi anni ’50, Franco Modigliani e il suo studente Richard Brumberg elaborarono una teoria della spesa fondata sull’idea che gli individui effettuano scelte intelligenti su quanto desiderano spendere a ogni età, con il solo limite delle risorse disponibili nel corso della loro vita. Attraverso l’accumulo e il decumulo delle attività, chi lavora può provvedere alla propriapensione e, più in generale, può adattare i propri modelli di consumo alle esigenze che sipresentano alle diverse età, indipendentemente dal reddito disponibile in ogni momento della suavita. Questa semplice teoria conduce a previsioni rilevanti e non scontate per l’economia nel suo complesso, ad esempio che il risparmio nazionale dipende dal tasso di crescita del reddito nazionale e non dal suo livello, e che esiste una semplice relazione tra il livello della ricchezza nelsistema economico e la lunghezza del periodo trascorso in pensione. Tali previsioni, non verificabili negli anni ’50, hanno trovato considerevole sostegno empirico in successivi lavori di Modigliani e di altri ricercatori. Sebbene nel corso degli anni la teoria del consumo abbia subitonumerosi attacchi, i più recenti dei quali mossi da una coalizione di psicologi ed economisti,l’ipotesi del ciclo vitale rimane una parte essenziale del pensiero degli economisti.

El estudio se realizó en La Vega, Florencia, San Carlos, Costa Rica entre mayo y octubre en los años 2010 y 2011, en el mismo lote con la variedad CR 4477. Se establecieron cinco tratamientos: silicio al suelo, silicio al suelo más plaguicidas (alternativas químicas, silicio foliar, silicio foliar más plaguicidas y testigo comercial. Como fuente se utilizaron si- licio en polvo al 70% de SiO2, aplicado quince días antes de siembra en dosis de 100 kg SiO2/ha, y líquido concentrado 40% SiO2 y 36% MgO, aplicado al follaje en dosis de 4 l/ha a los 17 y 30 días después de la siembra.

    Full Text Available FUNDAMENTO: Las parasitosis intestinales en los niños constituyen un problema de salud pública que debe ser valorado periódicamente en cada región. En este trabajo se aborda, por primera vez en la región natural del Valle del Guadalquivir, un estudio amplio sobre la prevalencia del parasitismo intestinal en la población infantil de la zona. MÉTODOS: Durante el período 1994-1996, mediante análisis coprológico y método de Graham, se ha estudiado a 1.917 niños y niñas asintomáticos, con edades comprendidas entre seis y diez años, residentes en veinte localidades del Valle del Guadalquivir. RESULTADOS: El índice global de parasitación ha sido del 27,12 %. Las especies parásitas detectadas, así como sus prevalencias fueron: Enterobius vermicularis (20,44%, Giardia lamblia (5,05%, Entamoeba coli (2,45%, Endolimax nana (1,61%, Entamoeba histolytica (0,31%, Entamoeba hartmanni (0,05%, Iodamoeba bütschlii (0,05%. CONCLUSIONES: La prevalencia global encontrada es similar a la de otras regiones españolas, aunque quizás pueda considerarse algo más favorable. No se detectan geohelmintos, debido posiblemente a la mejora de la infraestructura higiénico-sanitaria y a los efectos de la prolongada sequía en la zona. La giardiasis, a diferencia de las restantes protozoosis, mantiene una prevalencia relativamente alta.

El valor de realizar este proyecto, está en desocultar los múltiples significados que en la realidad vivida por los seres cuidadores primarios y en los seres cuidados; son esas distintas formas de percibir la existencia, influido por el conocimiento de lo ancestral, los sentimientos y la sabiduría de la cultura que cada uno posee para expresarse en las múltiples formas que el cuidado lo acontece y lo requiere para dar el sentido cultural característico y diferenciado que se percibe en el modo de cuidar y la satisfacción de quien lo recibe y lo ofrece. Este aspecto fue valioso para la comunidad académica del programa de enfermería, porque ubicó epistémicamente la transculturalidad del cuidado como una mirada y forma de enseñar transdisciplinariamente, enseñando y ofreciendo el cuidado desde la cultura, sentimientos y pensamientos del ser cuidado para el mantenimiento de la vida y la salud, en la que estudiantes de enfermeria desde sus primeras experiencias formativas deben incursionar en la intervención holística que se requiere en el cuidado de la salud y de la vida.

Durante las últimas décadas, se ha producido un enorme crecimiento y especialización de las ciencias del deporte y el lema del 18º Congreso del European College of Sport Sciences (ECSS “Unificar las ciencias del deporte” representa desafiar este proceso de fragmentación. El lema conlleva un cambio de la especialización a la integración, de una concepción de los sistemas vivos basada en la teoría de la información y la ingeniería a una de base biológica, de la investigación multidisciplinaria a la transdisciplinaria. Pero aparece una pregunta: ¿es posible integrar las áreas fragmentadas y facilitar la transferencia de los principios explicativos teóricos, técnicas y perspectivas metodológicas entre disciplinas? En el marco de las contribuciones hechas en el congreso, este artículo tiene como objetivo introducir enfoques científicos ya extendidos en los ámbitos de la física, la química, la biología (incluyendo las ómicas y las ciencias sociales, y que centradas en las interacciones dinámicas complejas de los componentes sistémicos (proteínas, células, organismos, grupos, sociedades, revelan principios explicativos generales que contribuyen a la unificación del conocimiento.

    Full Text Available Se analiza el trabajo clave de Max Weber, La ética protestante y el espíritu del capitalismo, desde la perspectiva de la Sociología de las Emociones. Aunque la inclusión de las emociones de los fenómenos sociales es clave para entender la idea de Weber sobre el dogma de la predestinación, los sociólogos han trivializado el papel de la emoción. Tras detallar la creencia de Weber en que el espíritu del capitalismo parte del conocimiento de que el destino del hombre está predeterminado (la ética protestante, se destaca que la angustia, más específicamente la humillación, invocada por esta creencia, debe figurar dentro de cualquier teoría acerca de la cultura. El sentimiento de humillación es explorado a través de los componentes cognitivos, evaluativos y emotivos de la cultura, proporcionando una mejor comprensión de la omnisciencia divina, la falta de respeto que la humanidad se merece y la ausencia de felicidad. A causa de la humillación y la falta de dignidad sufrida en muchos niveles, el hombre busca el orgullo personal, el éxito mundano y la modernidad, olvidando la humildad, la salvación eterna y la tradición.
