    Full Text Available Abstract Background Rates of caesarean section are progressively increasing in many parts of the world. As a result of psychosocial factors there has been an increasing tendency for pregnant women without justifiable medical indications for caesarean section to ask for this procedure in China. A critical examination of this issue in relation to maternal outcomes is important. At present there are no clinical trials to help assess the risks and benefits of caesarean section in low risk women. To fill the gap left by trials, this indication-matched cohort study was carried out to examine prospectively the outcomes of caesarean section on women with no absolute obstetric indication compared with similar women who had vaginal delivery. Methods An indication-matched cohort study was undertaken to compare maternal outcomes following caesarean section with those undergoing vaginal delivery, in which the two groups were matched for non-absolute indications. 301 nulliparous women with caesarean section were matched successfully with 301 women who delivered vaginally in the Maternal and Children's Hospitals (MCHs in Shanghai, China. Logistic regression model or binomial regression model was used to estimate the relative risk (RR directly. Adjusted RRs were calculated adjusting for propensity score and medical indications. Results The incidence of total complications was 2.2 times higher in the caesarean section group during hospitalization post-partum, compared with the vaginal delivery group (RR = 2.2; 95% CI: 1.1-4.4. The risk of haemorrhage from the start of labour until 2 hours post-partum was significantly higher in the caesarean group (RR = 5.6; 95% CI: 1.2-26.9. The risk of chronic abdominal pain was significantly higher for the caesarean section group (RR = 3.6; 95% CI: 1.2-10.9 than for the vaginal delivery group within 12 months post-partum. The two groups had similar incidences of anaemia and complicating infections such as wound complications

Methods: Nulliparous and adolescent women, 25 years of age or younger, using the frameless copper IUD or the frameless LNG-releasing intrauterine system (IUS, were selected from previous studies and a current multicenter post-marketing study with the frameless copper IUD. The small copper-releasing GyneFix® 200 IUD consists of four copper cylinders, each 5 mm long and only 2.2 mm wide. The frameless FibroPlant® LNG-IUS consists of a fibrous delivery system releasing the hormone levonorgestrel (LNG-IUS. The main features of these intrauterine contraceptives are that they are frameless, flexible, and anchored to the fundus of the uterus. Results: One hundred and fifty-four nulliparous and adolescent women participated in the combined study. One pregnancy occurred with the GyneFix 200 IUD after unnoticed early expulsion of the device (cumulative pregnancy rate 1.1 at one year. Two further expulsions were reported, one with the GyneFix 200 IUD and the other with the FibroPlant LNG-IUS. The cumulative expulsion rate at one year was 1.1 with the copper IUD and 2.2 with the LNG-IUS. The total discontinuation rate at one year was low (3.3 and 4.3 with the copper IUD and LNG-IUS, respectively and resulted in a high rate of continuation of use at one year (96.7 with the copper IUD and 95.7 with the LNG-IUS, respectively.

    Intra-uterine device (IUD) is one of the birth control methods, which is available for nulliparous women, even though misconceptions still remain in medical or popular opinion. Only 1.3 % of nulliparous have a IUD as contraception in France while it is the second methods used by all women, after pill. The best contraception is the one chosen by women; however, the choice for a nulliparous of an IUD may be really difficult, despite the increasing number of women wishing to use it. Long-acting reversible contraceptives utilization, including IUD, is probably one of the issues to decrease the unintended pregnancies. An exhaustive and clear information about IUD is necessary to allow an informed and real choice. This prescription must consider contraindications and medical conditions for safe insertion, especially to avoid infection by screening STD (Chlamydia trachomatis and Nesseria gonorrhoeae) in nulliparous womeneffected with usual precautions and short or SL IUD preferred. Even if side effects such as expulsion, pelvic pains or dysmenorrhea are more frequent by nulliparous, IUD is a first intention choice for contraception to be consider, that women could obtain easily, including in emergency contraception situation.

    To understand the relationship between cervical length and the risk of prematurity in parous women without a history of preterm delivery. Data from 2,998 singleton pregnancies enrolled in a multicenter, observational cohort study were analyzed. We subgrouped the population into the following categories: those with history of at least one spontaneous preterm birth (n=467); nulliparous (n=1,237); and parous with a history of at least one term birth and no previous preterm birth (low-risk history group, n=1,284). The relationship between cervical length (measured between 22 and 24 6/7 weeks of gestation) and preterm birth was examined using logistic regression [corrected].Assuming a 40% risk reduction with the use of vaginal progesterone, we calculated the number needed to screen to prevent one preterm birth. An inverse relationship between cervical length and risk of preterm birth was demonstrated for each subgroup. A short cervix (15 mm or less) was identified in only 0.93% of the low-risk group participants compared with 3.4% of the previous preterm birth group participants and 2.1% of nulliparous women. The overall rate of preterm birth was lowest (10.5%) in the low-risk history group; however, the rate of preterm birth for these women with a short cervix was 25%. For a cervical length cutoff of 15 mm or less, preventing one spontaneous delivery before 34 weeks of gestation would require screening 167 (95% confidence interval [CI] 112-317) women with a previous preterm birth, 344 (95% CI 249-555) nulliparous women, and 1,075 (95% CI 667-2,500) women at low risk. Although ultrasonographic short cervix is a risk factor for preterm birth among parous women with exclusively term births, the incidence of a short cervix is very low. The number needed to screen to prevent one preterm birth is considerably greater for women who have a low-risk obstetric history. : II.

    Full Text Available The genital organs of domestic animals are usually colonized by several microorganisms. This paper aims at describing the uterine and vaginal microbiota of nulliparous and non-nulliparous agoutis, which belong to the Catanduva City Zoo, Sao Paulo, Brazil. During the procedure of ovariosalpingohisterectomy, material was collected for microbiological analysis through the introduction of sterile swabs in the vagina and in each uterine horn. The presence of Proteus sp. was observed in the uterine material of only one animal. In the vaginal material of all animals, several bacteriae (Proteus sp., Escherichia coli, Citrobacter sp., Pseudomonas sp., and Staphylococcus sp. and yeasts were found. The vaginal and uterine microbiota of agoutis presents a colonization pattern different from that observed in other domestic animals, in women, and in female rats.

    Introduction The timing of when a woman is admitted to the hospital for labor care following spontaneous contraction onset may be among the most important decisions that labor attendants make as it can influence care patterns and birth outcomes. The aims of this study were to estimate the percentage of low-risk, nulliparous women at term who are admitted to labor units prior to active labor and to evaluate the effects of the timing of admission (i.e., pre-active versus active labor) on labor interventions and mode of birth. Methods Obstetrics data from low-risk, nulliparous women with spontaneous labor onset at term gestation (N = 216) were merged from two prospective studies conducted at three large, Midwestern hospitals. Baseline characteristics, labor interventions, and outcomes were compared between groups using Fisher’s exact and Mann-Whitney U tests, as appropriate. Likelihoods for oxytocin augmentation, amniotomy, and cesarean delivery were assessed by logistic regression. Results Of the sample of 216 low-risk nulliparous women, 114 (52.8%) were admitted in pre-active labor and 102 (47.2%) were admitted in active labor. Women admitted in pre-active labor were more likely to undergo oxytocin augmentation (84.2% and 45.1%, respectively; odds ratio (OR) 6.5, 95% confidence interval (CI) 3.43–12.27) but not amniotomy (55.3% and 61.8%, respectively; OR 0.8, 95% CI 0.44–1.32) when compared to women admitted in active labor. The likelihood of cesarean delivery was higher for women admitted before active labor onset (15.8% and 6.9%, respectively; OR 2.6, 95% CI 1.02–6.37). Discussion Many low-risk nulliparous women with regular, spontaneous uterine contractions are admitted to labor units before active labor onset, which increases their likelihood of receiving oxytocin and being delivered via cesarean section. An evidence-based, standardized approach for labor admission decision-making is recommended to decrease inadvertent admissions of women in pre

  15. Regional brain responses in nulliparous women to emotional infant stimuli.

    Directory of Open Access Journals (Sweden)

    Jessica L Montoya

    Full Text Available Infant cries and facial expressions influence social interactions and elicit caretaking behaviors from adults. Recent neuroimaging studies suggest that neural responses to infant stimuli involve brain regions that process rewards. However, these studies have yet to investigate individual differences in tendencies to engage or withdraw from motivationally relevant stimuli. To investigate this, we used event-related fMRI to scan 17 nulliparous women. Participants were presented with novel infant cries of two distress levels (low and high and unknown infant faces of varying affect (happy, sad, and neutral in a randomized, counter-balanced order. Brain activation was subsequently correlated with scores on the Behavioral Inhibition System/Behavioral Activation System scale. Infant cries activated bilateral superior and middle temporal gyri (STG and MTG and precentral and postcentral gyri. Activation was greater in bilateral temporal cortices for low- relative to high-distress cries. Happy relative to neutral faces activated the ventral striatum, caudate, ventromedial prefrontal, and orbitofrontal cortices. Sad versus neutral faces activated the precuneus, cuneus, and posterior cingulate cortex, and behavioral activation drive correlated with occipital cortical activations in this contrast. Behavioral inhibition correlated with activation in the right STG for high- and low-distress cries relative to pink noise. Behavioral drive correlated inversely with putamen, caudate, and thalamic activations for the comparison of high-distress cries to pink noise. Reward-responsiveness correlated with activation in the left precentral gyrus during the perception of low-distress cries relative to pink noise. Our findings indicate that infant cry stimuli elicit activations in areas implicated in auditory processing and social cognition. Happy infant faces may be encoded as rewarding, whereas sad faces activate regions associated with empathic processing. Differences

    The widespread use of prostate cancer screening has led to a stage migration resulting in an increase in the diagnosis of low-risk disease, which currently accounts for 40-50% of diagnosed forms. New therapeutic strategies have been developed in order to minimize the risk of overtreatment. A systematic review of the literature over the past 20 years was performed using the Medline database. The literature selection was based on evidence and practical considerations. Low-risk tumors are conventionally defined by the d'Amico classification. The use of multiparametric MRI helps to better characterize these tumors. The contribution of molecular biology remains to be determined in clinical practice. Novel therapeutic options for low-risk disease are currently being evaluated. The new therapeutic strategies are evolving. They seek to reduce overtreatment without compromising oncological success.

    This study aimed to investigate the effects of age on pelvic floor symptoms (PFSs) in nulliparous women. Eighty community-dwelling nulliparous women, aged 21 to 70 years, were recruited. Pelvic floor support was assessed with pelvic organ prolapse quantification system. Participants completed the Pelvic Floor Distress Inventory 20 and Pelvic Floor Impact Questionnaire 7. Sexual function was assessed with the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire 12 and health status with the Short-Form Health Survey. The correlation between age and questionnaire scores was evaluated using Pearson coefficient. Logistic regression assessed predictors associated with PFS. Participants had a median age of 47 years, average body mass index of 28.3 kg/m, and most were white; 52.5% were healthy and 30% were postmenopausal. The most common stage of prolapse was stage I.Age was associated with slightly higher Pelvic Floor Distress Inventory-20 scores (r = 0.41, P = 0.002), corresponding to more bothersome PFS, and lower Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire-12 scores, corresponding to worsening sexual function with advancing age (r = -0.41, P = 0.0012). There was no association between age and overall Pelvic Floor Impact Questionnaire scores (P = 0.12). For symptomatic patients, logistic regression showed age to be associated with increased odds of having PFS [odds ratio (OR), 1.881; 95% confidence interval (CI), 1.216-2.91]. Menopausal status was not associated with increased odds of reporting symptoms (OR, 3.05; 95% CI, 0.80-11.62). When age and age by menopause were incorporated in the model, age remained a significant predictor of having PFS (OR, 1.78; 95% CI, 1.13-2.78). In this population of community-dwelling nulliparous women, age was associated with worsening sexual function and slightly increased odds of reporting symptoms of pelvic floor disorders.

    To quantify the "normal" adolescent experience after IUD insertion, in order to provide appropriate counseling for future adolescents. Prospective cohort study. Marshall University Department of Obstetrics and Gynecology generalist and adolescent gynecology clinics. Nulliparous adolescents age 13-18 and parous adults ≥18 years receiving a levonorgestrel intrauterine system (LNG-IUS). Visual analog scale pain score (VAS) and medication log was used for data collection for two weeks after LNG-IUS. A separate chart review was completed for demographic factors and indications for procedure. VAS pain scores and medication use was compared between groups. 93 subjects returned the VAS record and medication log (46 adolescents and 47 adults). There was no difference in the incidence of endometriosis or dysmenorrhea, but there was a higher prevalence of menorrhagia among adolescents (65.2% vs 21.3%, p= 5 during the first three days, p=0.022. A statistical difference in amount of ibuprofen recorded was only noted on day 1 (p=.023) and day 4 (p=.046). Nulliparous adolescents undergoing LNG-IUS placement experience more post-insertional discomfort compared to parous adults; however, this method should still be considered first-line in this age group.

    Neutrophil-lymphocyte ratio (NLR) and BMI were examined as pre-operative predictors for lymph node metastases in patients with low-risk endometrial cancer. The study was a retrospective analysis of 534 endometrial cancer patients that underwent hysterectomy and lymph node dissection. Included subjects had a preoperative diagnosis of a grade 1 or 2 endometrioid carcinoma and no macroscopic extrauterine disease. We compared node-negative to node-positive patients to identify correlates of node-positive disease. The node-positive group presented with lower BMI than the node-negative group, 31.5 and 34.4, respectively (p = .03). The mean NLR was higher in the node-positive group 3.4 vs 2.9 (p = .08), showing a trend towards significance on univariate analysis. On multivariate analysis, lower BMI was found to be an independent predictor for nodal metastasis. Our data suggest that lower BMI is a risk factor for lymph nodes involvement in low-risk endometrial cancer. Impact statement Most endometrial cancer patients have low-risk disease with low risk for lymph nodes metastasis. In order to reduce the number of patients that will undergo unnecessary lymph node dissection, different types of preoperative predictors for lymph node involvement were studied. CA 125 and different imaging modalities were found as useful predictors for more advanced disease. Less studied predictors are the systemic inflammatory response markers and patient's BMI. This study suggests that lower BMI is a risk factor for lymph node involvement in low-risk endometrial cancer. The neutrophil to lymphocyte ratio was close to significance as a predictor for lymph node involvement. In practice, physicians might favour comprehensive lymph node dissection when there is a doubt regarding the procedure but the patient is lean. The study's conclusion can be utilised for triaging patients to general gynaecologist vs gynaecologic oncologist. Further research should focus on combining predictors such as

    To determine factors associated with perception of pregnancy risk using a conceptual framework based on a review of the relevant literature and the psychometric model of risk perception. A correlational study. Ambulatory care and antepartum units of two tertiary hospitals and selected obstetricians' offices and prenatal classes in Winnipeg, Canada. A convenience sample of nulliparous women in their third trimester with a singleton pregnancy. Between December 2009 and January 2011, the following questionnaires were completed by 159 nulliparous women: the Perception of Pregnancy Risk Questionnaire, the Pregnancy-related Anxiety scale, Knowledge of Maternal Age-related Risks of Childbearing Questionnaire, the SF-12v2 Health Status Survey, the Multidimensional Health Locus of Control, and the Prenatal Scoring Form. Pearson's r correlations and stepwise multivariable linear regression analyses were conducted to achieve the research objectives. Of the eight proposed factors in the conceptual framework, five factors were significant predictors of perception of pregnancy risk, including pregnancy-related anxiety, maternal age, medical risk, perceived internal control, and gestational age, accounting for 47% to 49% of the variance in risk perception. An interaction between the pregnancy-related anxiety score and maternal age was found. These results contribute to the literature on perception of pregnancy risk by identifying a new predictor (gestational age), supporting the role of previously known factors in the state of pregnancy, and proposing pregnancy-related anxiety as a pregnancy dread factor in risk perception theories. This knowledge may have implications for developing more effective risk communication models. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Present within each of these studies were nulliparous women with risk factors for cephalopelvic disproportion. Risk factors for cephalopelvic disproportion in nulliparous women are especially important because they represent the precursors for the most common indication for primary cesarean delivery. Cases. Three examples of exposure of urban nulliparous women to the AMOR-IPAT protocol are presented. Each woman's risk factor profile for Cephalopelvic Disproportion (CPD was used to estimate her Upper Limit of Optimal Time of Vaginal Delivery for CPD (UL-OTDcpd. Labor management and clinical outcomes for each case are presented. A simple table summarizing induction rates and birth outcome rates of exposed versus nonexposed nulliparous women is also presented. Conclusion. Because the mode of delivery of the first birth substantially impacts birth options in later pregnancies, the impact of AMOR-IPAT on nulliparous patients is particularly important. Determining the UL-OTDcpd in nulliparous patients, and carefully inducing each patient who has not entered labor by her UL-OTDcpd, may be an effective way of lowering rates of cesarean delivery in nulliparous women.

No differences were found in the other secondary outcomes. There were no maternal or perinatal deaths and only one woman, in the 125 mL/h group, developed pulmonary edema. The findings persisted regardless of the type of intravenous fluid used. No significant reduction in the incidence of cesarean delivery was demonstrated in women with unrestricted oral intake; however, this was limited to only two studies evaluating 254 women. Our findings provide evidence that the duration of labor in low-risk nulliparous women may be shortened by a policy of intravenous fluids at a rate of 250 mL/h rather than 125 mL/h. A rate of 250 mL/h seems to be associated with a reduction in the incidence of cesarean delivery compared to 125 mL/h. The number needed to treat to prevent one cesarean delivery is 18 women. Our data support increased hydration among nulliparous women in labor when oral intake is restricted. Further study is needed regarding risks and benefits of increased hydration among women with unrestricted oral intake, those undergoing induction of labor, and those with medical comorbidities. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    The validity of the risk assessment in predicting tooth loss due to periodontitis or disease progression was explored. Systemic factors, smoking status, bleeding on probing (BoP) percentage, number of residual pockets (probing pocket depth ≥6 mm), tooth loss, and alveolar bone loss in relation to age were the variables of the risk assessment. Based on an improving or deteriorating risk assessment in 2005 compared with 1999, 89 patients were divided into either a high- or low-risk group. Findings were compared with the 2008 outcome.   Using BoP≤20% as the cut-off, the relationship between BoP and interleukin-1 genotype status was neither significant in 2005 nor in 2008. Neither the high- nor low-risk group was predictive for tooth loss. Patients displayed similar proportions of probing pocket depths ≥6mm in 2005 and in 2008. Linear stepwise regression analysis demonstrated that only the number of supportive periodontal therapy visits explained the number of teeth lost due to periodontitis (Pperiodontal risk assessment model applied within a supportive periodontal therapy period of 3 years, had limitations in predicting future tooth loss. © 2011 Blackwell Publishing Asia Pty Ltd.

    To explore nulliparous women's perceptions of decision making regarding mode of delivery under China's two-child policy. Qualitative descriptive design with in-depth semi-structured interviews. Postnatal wards at a tertiary specialized women's hospital in Shanghai, China. 21 nulliparous women 2-3 days postpartum were purposively sampled until data saturation. In-depth semi-structured interviews were conducted between October 8th, 2015 and January 31st, 2016. Two overarching descriptive categories were identified: (1) women's decision-making process: stability versus variability, and (2) factors affecting decision making: variety versus interactivity. Four key themes emerged from each category: (1) initial decision making with certainty: anticipated trial of labour, failed trial of labour, 'shy away' and compromise, anticipated caesarean delivery; (2) initial decision making with uncertainty: anticipated trial of labour, failed trial of labour, 'shy away' and compromise; (3) internal factors affecting decision making: knowledge and attitude, and childbirth self-efficacy; and (4) external factors affecting decision making: social support, and the situational environment. At the initial period of China's two-child policy, nulliparous women have perceived their decision-making process regarding mode of delivery as one with complexity and uncertainty, influenced by both internal and external factors. This may have implications for the obstetric setting to develop a well-designed decision support system for pregnant women during the entire pregnancy periods. And it is recommended that care providers should assess women's preferences for mode of delivery from early pregnancy and provide adequate perinatal support and continuity of care for them.

The vaginal instrumental delivery rate was higher in the two-balloon groups than in the dilator group. The volume of intrapartum hemorrhage was lowest in the dilator group. No significant difference in the frequencies of uterine rupture and intrauterine infection were observed among the dilator and two-balloon groups. With regard to neonatal outcomes, the frequency of a low Apgar score was statistically significantly lower in the dilator group than in the two-balloon groups. Moreover, the frequency of neonatal death tended to be lower in the dilator group than in the two-balloon groups.With regard to cervical ripening for labor induction in nulliparous women at term, the vaginal delivery rate on using a dilator and on using a balloon seems to be equivalent.

    Full Text Available The post-cervical artificial insemination (PCAI in sows increases semen performance compared to cervical artificial insemination (CAI. In Argentina the use of the PCAI is restricted to multiparous while it is not applied to nulliparous. The aim of this study was to compare porcine CAI and PCAI in nulliparous and multiparous. Pregnancy rates and number of live pups with CAI and PCAI in nulliparous and multiparous, assessing advantages and disadvantages of each method were compared. This is a small-scale work (4 CAI and 7 PCAI in nulliparous, 3 CAI and 3 PCAI in multiparous in a small field productive site in the Province of Buenos Aires. Here the boar was omitted for heat detection and to stimulate the sow during AI. Pregnancy rates and the number of pups born alive per pregnant sow were similar with the two techniques and two categories. The PCAI is a good practice in nulliparous and multiparous because this technique increases semen performance compared to CAI and it is omitted the presence of the boar.

    Growth recovery lines, also known as growth arrest lines, are transverse radiodense metaphyseal bands that develop due to a temporary arrest of endochondral ossification caused by local or systemic insults. To determine if growth recovery lines are more common in infants at high risk versus low risk for abuse. Reports of American College of Radiology compliant skeletal surveys (1999-2013) were reviewed with clinical records. Infants at low risk for abuse had a skull fracture without significant intracranial injury, history of a fall and clinical determination of low risk (child protection team/social work assessment). Infants at high risk had significant intracranial injury, retinal hemorrhages, other skeletal injuries and clinical determination of high risk. There were 52 low-risk infants (mean: 4.7 months, range: 0.4-12 months) and 21 high-risk infants (mean: 4.2 months, range: 0.8-9.1 months). Two blinded radiologists independently evaluated the skeletal survey radiographs of the knees/lower legs for the presence of at least one growth recovery line. When growth recovery lines are scored as probably present or definitely present, their prevalence in the low-risk group was 38% (standard deviation [SD] = 8%; reader 1 = 17/52, reader 2 = 23/52) vs. 71% (SD = 7%; reader 1 = 16/21, reader 2 = 14/21) in the high-risk group (P < 0.001; odds ratio 4.0, 95% CI: 1.7-9.5). Growth recovery lines are encountered at a significantly higher rate in infants at high risk vs. low risk for abuse. This suggests that abused infants are prone to a temporary disturbance in endochondral ossification as a result of episodic physiological stresses. (orig.)

    Our aim was to assess whether differences in the ages of nulliparous women affect: (1) interobserver reliability, and (2) visualization of the levator ani (LA) muscle subdivisions in nulliparous women using 3D endovaginal ultrasound (3D-EVUS). This was a cross-sectional study. Community-dwelling nulliparous women ages 21-70 years were recruited. Participants underwent a standard examination and a 3D-EVUS. LA subdivisions of interest included the puboperinealis, puboanalis, pubococcygeus, puborectalis, and ileococcygeus muscles. Each ultrasound (US) volume was scored using a validated scale and assessed by two observers. Defect severity was scored for each muscle from 0 (no defect) to 6 (complete muscle loss). A summed score of the two sides was grouped as normal (0), minor (1-3), or major (4-6). Bias was examined using Bland-Altman plots. Intraclass coefficients were calculated to report agreement of total scores. Spearman's rank correlation was used to evaluate the association between age and LA scores. Eighty nulliparous women were evaluated. Exact agreement for bilateral scoring of each LA subdivision ranged from 82 % to 84 %. Bilateral scoring of the puboperinealis, puborectalis, and ileococcygeus showed moderate to substantial agreement. Bilateral scores of the puboperinealis demonstrated substantial agreement between observers, with an ICC of 0.8 and a mean difference of -0.2 using the Bland-Altman analysis. When women were analyzed by age decade, reader agreement was overall good to excellent. There was no significant correlation between increasing age and total LA muscle scores (r = 0.179, p = 0.113). Interobserver reliability or visualization of the LA muscle in nulliparous women was not affected by a woman's age.

Eighty-two nulliparous women were identified for this retrospective cohort study over a period of three months on either side of the changed practice. Forty-four women received Prostin and 38 received Cervidil. Baseline characteristics were similar amongst the groups including maternal age, mean gestational age, and modified Bishop’s score at the commencement of IOL. The incidence of amniotomy, oxytocin augmentation of labour, and rate of epidural use did not differ significantly between the groups. The mean time to delivery (vaginally or abdominally showed a significant difference, with women receiving Prostin delivering earlier than those having Cervidil (=0.018. Women receiving Prostin were more likely to have assisted vaginal delivery compared to the Cervidil group (=0.04.

    Induction of labour is associated with increased risk for caesarean delivery among nulliparous women. The aims of this study were to evaluate the risk factors for caesarean delivery and to investigate the risk of maternal and neonatal infections in nulliparous women undergoing induction of labour by Foley catheter. This clinical retrospective study of 432 nulliparous women with singleton pregnancy and intact amniotic membranes at or beyond 37 gestational weeks scheduled for induction of labour by Foley catheter was conducted over the course of one year, between January 2012 and January 2013, in Helsinki University Hospital. The main outcome measures were caesarean section rate and maternal and neonatal infections. Univariate and multivariate logistic regressions were used to estimate relative risks by odds ratios with 95% confidence intervals. The caesarean section rate was 39.1% (n = 169). In multivariate regression analysis, the factors associated with caesarean section were the need for oxytocin for labour induction [OR 2.9 (95% CI 1.8-4.5) p infection rate was 6.3%, and the clinical neonatal infection rate was 2.8%. In multivariate analysis, gestational diabetes was associated with maternal intrapartum infection [OR 4.3 (95% CI 1.7-11.0, p = 0.002] and early epidural analgesia with neonatal clinical sepsis [OR 10.5 (95% CI 1.4-76), p = 0.02]. Oxytocin induction and early epidural analgesia were associated with caesarean delivery. Gestational diabetes and early epidural analgesia were associated with infectious morbidity. Since the first caesarean delivery has a major impact on subsequent pregnancies, optimising labour induction among nulliparous women is important.

    To evaluate the effectiveness of inhaled nitrous oxide for pain management among nulliparous women undergoing intrauterine device (IUD) insertion. A double-blind, randomized controlled trial was conducted among nulliparous women aged 13-45years who underwent IUD insertion at a US center between October 1, 2013, and August 31, 2014. Using a computer-generated randomization sequence, participants were randomly assigned to inhale either oxygen (O 2 ) or a mixture of 50% nitrous oxide and 50% oxygen (N 2 O/O 2 ) through a nasal mask for 2minutes before insertion. Only the person administering the inhalation agent was aware of group assignment. The primary outcome was maximum pain assessed 2minutes after insertion via a 100-mm visual analog scale. Analyses were by intention to treat. Forty women were assigned to each group. Mean maximum pain score at the time of insertion was 54.3±24.8mm for the N 2 O/O 2 group and 55.3±20.9mm for the O 2 group (P=0.86). Adverse effects were reported for 6 (15%) women in the N 2 O/O 2 group and 7 (18%) in the O 2 group (P=0.32). N 2 O/O 2 did not reduce the pain of IUD insertion among nulliparous women.

    The goal of this study was to evaluate normal hiatal dimensions in the third trimester in nulliparous Thai pregnant women and to establish which biometric factors were associated with various pregnancy outcomes. Fifty-seven consecutive nulliparous pregnant Thai women in their third trimester were recruited on a voluntary basis from April to October 2014. All subjects underwent four-dimensional (4D) translabial ultrasonography. Hiatal biometric parameters were measured at rest, while performing a Valsalva maneuver, and during contraction. Information about the patients’ eventual deliveries was obtained from their medical records. The mean values of the patients’ age, body mass index, and gestational age at the time of examination were 27.4±5.47 years, 26.7±3.48 kg/m{sup 2}, and 36.6±1.49 weeks, respectively. No subjects had vaginal lumps or experienced prolapse greater than stage 1 of the Pelvic Organ Prolapse Quantification system. Ultrasonography showed that the mean values of the hiatal area at rest, while performing a Valsalva maneuver, and during contraction were 13.10±2.92 cm{sup 2}, 17.50±4.81 cm{sup 2}, and 9.69±2.09 cm{sup 2}, respectively. The hiatal area at rest, the axial measurement at rest, and the axial measurement while performing a Valsalva maneuver were significantly associated with the route of delivery (P=0.02, P=0.04, and P=0.03, respectively). The route of delivery was associated with hiatal biometric values measured using 4D translabial ultrasonography, based on the results of nulliparous Thai women in the third trimester.

    The call for women-centred approaches to reduce labour interventions, particularly primary caesarean section, has renewed an interest in gaining a better understanding of natural labour progression. To synthesise available data on the cervical dilatation patterns during spontaneous labour of 'low-risk' women with normal perinatal outcomes. PubMed, EMBASE, CINAHL, POPLINE, Global Health Library, and reference lists of eligible studies. Observational studies and other study designs. Two authors extracted data on: maternal characteristics; labour interventions; the duration of labour centimetre by centimetre; and the duration of labour from dilatation at admission through to 10 cm. We pooled data across studies using weighted medians and employed the Bootstrap-t method to generate the corresponding confidence bounds. Seven observational studies describing labour patterns for 99 971 women met our inclusion criteria. The median time to advance by 1 cm in nulliparous women was longer than 1 hour until a dilatation of 5 cm was reached, with markedly rapid progress after 6 cm. Similar labour progression patterns were observed in parous women. The 95th percentiles for both parity groups suggest that it was not uncommon for some women to reach 10 cm, despite dilatation rates that were much slower than the 1-cm/hour threshold for most part of their first stage of labours. An expectation of a minimum cervical dilatation threshold of 1 cm/hour throughout the first stage of labour is unrealistic for most healthy nulliparous and parous women. Our findings call into question the universal application of clinical standards that are conceptually based on an expectation of linear labour progress in all women.

    Background: There is concern about increasing utilization of low-value health care services, including preoperative testing for low-risk surgical procedures. We investigated temporal trends, explanatory factors, and institutional and regional variation in the utilization of testing before low-risk procedures. Methods: For this retrospective cohort study, we accessed linked population-based administrative databases from Ontario, Canada. A cohort of 1 546 223 patients 18 years or older underwent a total of 2 224 070 low-risk procedures, including endoscopy and ophthalmologic surgery, from Apr. 1, 2008, to Mar. 31, 2013, at 137 institutions in 14 health regions. We used hierarchical logistic regression models to assess patient- and institution-level factors associated with electrocardiography (ECG), transthoracic echocardiography, cardiac stress test or chest radiography within 60 days before the procedure. Results: Endoscopy, ophthalmologic surgery and other low-risk procedures accounted for 40.1%, 34.2% and 25.7% of procedures, respectively. ECG and chest radiography were conducted before 31.0% (95% confidence interval [CI] 30.9%–31.1%) and 10.8% (95% CI 10.8%–10.8%) of procedures, respectively, whereas the rates of preoperative echocardiography and stress testing were 2.9% (95% CI 2.9%–2.9%) and 2.1% (95% CI 2.1%–2.1%), respectively. Significant variation was present across institutions, with the frequency of preoperative ECG ranging from 3.4% to 88.8%. Receipt of preoperative ECG and radiography were associated with older age (among patients 66–75 years of age, for ECG, adjusted odds ratio [OR] 18.3, 95% CI 17.6–19.0; for radiography, adjusted OR 2.9, 95% CI 2.8–3.0), preoperative anesthesia consultation (for ECG, adjusted OR 8.7, 95% CI 8.5–8.8; for radiography, adjusted OR 2.2, 95% CI 2.1–2.2) and preoperative medical consultation (for ECG, adjusted OR 6.8, 95% CI 6.7–6.9; for radiography, adjusted OR 3.6, 95% CI 3.5–3.6).

    Full Text Available Adult attachment style is a key for understanding emotion regulation and feelings of security in human interactions as well as for the construction of the caregiving system. The caregiving system is a group of representations about affiliative behaviors, which is guided by the caregiver’s sensitivity and empathy, and is mature in young adulthood. Appropriate perception and interpretation of infant emotions is a crucial component of the formation of a secure attachment relationship between infant and caregiver. As attachment styles influence the ways in which people perceive emotional information, we examined how different attachment styles associated with brain response to the perception of infant facial expressions in nulliparous females with secure, anxious, and avoidant attachment styles. The event-related potentials of 65 nulliparous females were assessed during a facial recognition task with joy, neutral, and crying infant faces. The results showed that anxiously attached females exhibited larger N170 amplitudes than those with avoidant attachment in response to all infant faces. Regarding the P300 component, securely attached females showed larger amplitudes to all infant faces in comparison with avoidantly attached females. Moreover, anxiously attached females exhibited greater amplitudes than avoidantly attached females to only crying infant faces. In conclusion, the current results provide evidence that attachment style differences are associated with brain responses to the perception of infant faces. Furthermore, these findings further separate the psychological mechanisms underlying the caregiving behavior of those with anxious and avoidant attachment from secure attachment.

    Full Text Available Abstract Background A variable decision in managing community acquired pneumonia (CAP is the initial site of care; in-patient versus outpatient. These variations persist despite comprehensive practice guidelines. Patients with a Pneumonia Severity Index (PSI score lower than seventy have low risk for complications and outpatient antibiotic management is recommended in this group. These patients are generally below the age of fifty years, non-nursing home residents, HIV negative and have no major cardiac, hepatic, renal or malignant diseases. Methods A retrospective analysis of 296 low-risk CAP patients evaluated within a year one period at St. Agnes Hospital, Baltimore, Maryland was undertaken. All patients were assigned a PSI score. 208 (70% were evaluated and discharged from the emergency department (E.D. to complete outpatient antibiotic therapy, while 88 (30% were hospitalized. Patients were sub-stratified into classes I-V according to PSI. A comparison of demographic, clinical, social and financial parameters was made between the E.D. discharged and hospitalized groups. Results Statistically significant differences in favor of the hospitalized group were noted for female gender (CI: 1.46-5.89, p= 0.0018, African Americans (CI: 0.31-0.73, p= 0.004, insurance coverage (CI: 0.19-0.63, p= 0.0034, temperature (CI: 0.04-0.09, p= 0.0001 and pulse rate (CI: 0.03-0.14, p= 0.0001. No statistically significant differences were observed between the two groups for altered mental status, hypotension, tachypnea, laboratory/radiological parameters and social indicators (p>0.05. The average length of stay for in-patients was 3.5 days at about eight time's higher cost than outpatient management. There was no difference in mortality or treatment failures between the two groups. The documentation rate and justifications for hospitalizing low risk CAP patients by admitting physicians was less than optimal. Conclusions High fever, tachycardia, female gender

    Incidence of thyroid cancer is increasing in Spain and worldwide. Overall thyroid cancer survival is very high, and stratification systems to reliably identify patients with worse prognosis have been developed. However, marked differences exist between the different specialists in clinical management of low-risk patients with thyroid carcinoma. Almost half of all papillary thyroid carcinomas are microcarcinomas, and 90% are tumors < 2 cm that have a particularly good prognosis. However, they are usually treated more aggressively than needed, despite the lack of adequate scientific support. Surgery remains the gold standard treatment for these tumors. However, lobectomy may be adequate in most patients, without the need for total thyroidectomy. Similarly, prophylactic lymph node dissection of the central compartment is not required in most cases. This more conservative approach prevents postoperative complications such as hypoparathyroidism or recurrent laryngeal nerve injury. Postoperative radioiodine remnant ablation and strict suppression of serum thyrotropin, although effective for the more aggressive forms of thyroid cancer, have not been shown to be beneficial for the treatment of low risk patients, and may impair their quality of life. This guideline provides recommendations from the task force on thyroid cancer of the Spanish Society of Endocrinology and Nutrition for adequate management of patients with low-risk thyroid cancer.

    To determine the frequency of TP53 mutations and the level of p53 protein expression by immunohistochemistry (IHC) in low-risk myelodysplastic syndromes (MDS) with del(5q) and to assess their impact on disease progression. Pre- and postprogression bone marrow (BM) samples from 55 consecutive patients with International Prognostic Scoring System low risk (n = 32) or intermediate-1 risk (n = 23) were studied by next-generation sequencing of TP53. IHC for p53 was performed on 148 sequential BM samples. TP53 mutations with a median clone size of 11% (range, 1% to 54%) were detected in 10 patients (18%) already at an early phase of the disease. Mutations were equally common in low-risk and intermediate-1-risk patients and were associated with evolution to acute myeloid leukemia (5 of 10 v 7 of 45; P = .045). Nine of 10 patients carrying mutations showed more than 2% BM progenitors with strong p53 staining. The probability of a complete cytogenetic response to lenalidomide was lower in mutated patients (0 of 7 v 12 of 24; P = .024). By using sensitive deep-sequencing technology, we demonstrated that TP53 mutated populations may occur at an early disease stage in almost a fifth of low-risk MDS patients with del(5q). Importantly, mutations were present years before disease progression and were associated with an increased risk of leukemic evolution. TP53 mutations could not be predicted by common clinical features but were associated with p53 overexpression. Our findings indicate a previously unrecognized heterogeneity of the disease which may significantly affect clinical decision making.

    Accurate prediction of whether a nulliparous woman will have a vaginal delivery would be a major advance in obstetrics. The objective of the study was to develop such a model based on maternal characteristics and the results of intrapartum ultrasound. One hundred twenty-two nulliparous women in the first stage of labor were included in a prospective observational 2-centre study. Labor was classified as prolonged according to the respective countries' national guidelines. Fetal head position was assessed with transabdominal ultrasound and cervical dilatation by digital examination, and transperineal ultrasound was used to determine head-perineum distance and the presence of caput succedaneum. The subjects were divided into a testing set (n = 61) and a validation set (n = 61) and a risk score derived using multivariable logistic regression with vaginal birth as the outcome, which was dichotomized into no/cesarean delivery and yes/vaginal birth. Covariates included head-perineum distance, caput succedaneum, and occiput posterior position, which were dichotomized respectively into the following: ≤40 mm, >40 mm, <10 mm, ≥10 mm, and no, yes. Maternal age, gestational age, and maternal body mass index were included as continuous covariates. Dichotomized score is significantly associated with vaginal delivery (P = .03). Women with a score above the median had greater than 10 times the odds of having a vaginal delivery as compared with those with a score below the median. The receiver-operating characteristic curve showed an area under the curve of 0.853 (95% confidence interval, 0.678-1.000). A risk score based on maternal characteristics and intrapartum findings can predict vaginal delivery in nulliparous women in the first stage of labor. Copyright © 2015 Elsevier Inc.

    Full Text Available Introduction and Objectives: Nulliparous women with unplanned pregnancy experience high levels of anxiety, which may adversely affect maternal-fetal attachment. Therefore, in this study, we aimed to determine the effect of guided imagery on maternal-fetal attachment in nulliparous women with unplanned pregnancy. Materials and Methods: In this clinical trial, 67 nulliparous women with unplanned pregnancy were randomly divided into two groups of intervention (n=35 and control (n=32 in 2015. Data collection tools included a demographic form and London, DASS 21, and Cranley's maternal-fetal attachment questionnaires. In the intervention group, one session of guided imagery on maternal role was performed in 34th week of pregnancy in groups of four to seven. Afterwards, guided imagery CDs were given to mothers to be performed at home twice a week for two weeks; the control group only received the routine care. Maternal-fetal attachment was assessed before and two weeks after the intervention. To analyze the data, independent t-test, paired t-test, Chi-squared, Fisher’s exact test, and Mann-Whitney U tests were run using SPSS version 21. Results: Maternal mean age was 24.1±4.3 years, and most mothers (49.3% had high school education. Mean score of maternal-fetal attachment was significantly different between the intervention (94.26±6.7 and control (90.22 ± 9.5 groups after the intervention (P=0.04. Also, there was a significant difference between mean score of maternal-fetal attachment at the beginning and end of the intervention in the intervention and control groups (5.86±7.2 vs. 1.72±3.2; P=0.004. Conclusion: Guided imagery promoted maternal-fetal attachment in women with unplanned pregnancy; thus, it is recommended to use this method in prenatal care for these women.

    Full Text Available OBJECTIVE: This study aimed to compare the pelvic floor muscle strength of nulliparous and primiparous women. METHODS: A total of 100 women were prospectively distributed into two groups: Group 1 (G1 (n = 50 included healthy nulliparous women, and Group 2 (G2 (n = 50 included healthy primiparous women. Pelvic floor muscle strength was subjectively evaluated using transvaginal digital palpation. Pelvic floor muscle strength was objectively assessed using a portable perineometer. All of the parameters were evaluated simultaneously in G1 and were evaluated in G2 during the 20th and 36th weeks of pregnancy and 45 days after delivery. RESULTS: In G2, 14 women were excluded because they left the study before the follow-up evaluation. The median age was 23 years in G1 and 22 years in G2; there was no significant difference between the groups. The average body mass index was 21.7 kg/m² in G1 and 25.0 kg/m² in G2; there was a significant difference between the groups (p = 0.0004. In G2, transvaginal digital palpation evaluation showed significant impairments of pelvic floor muscle strength at the 36th week of pregnancy (p = 0.0006 and 45 days after vaginal delivery (p = 0.0001 compared to G1. Objective evaluations of pelvic floor muscle strength in G2 revealed a significant decrease 45 days after vaginal delivery compared to nulliparous patients. CONCLUSION: Pregnancy and vaginal delivery may cause weakness of the pelvic floor muscles.

    Full Text Available OBJECTIVES: To identify risk factors for spontaneous preterm birth (birth <37 weeks gestation with intact membranes (SPTB-IM and SPTB after prelabour rupture of the membranes (SPTB-PPROM for nulliparous pregnant women. DESIGN: Prospective international multicentre cohort. PARTICIPANTS: 3234 healthy nulliparous women with a singleton pregnancy, follow up was complete in 3184 of participants (98.5%. RESULTS: Of the 3184 women, 156 (4.9% had their pregnancy complicated by SPTB; 96 (3.0% and 60 (1.9% in the SPTB-IM and SPTB-PPROM categories, respectively. Independent risk factors for SPTB-IM were shorter cervical length, abnormal uterine Doppler flow, use of marijuana pre-pregnancy, lack of overall feeling of well being, being of Caucasian ethnicity, having a mother with diabetes and/or a history of preeclampsia, and a family history of low birth weight babies. Independent risk factors for SPTB-PPROM were shorter cervical length, short stature, participant's not being the first born in the family, longer time to conceive, not waking up at night, hormonal fertility treatment (excluding clomiphene, mild hypertension, family history of recurrent gestational diabetes, and maternal family history of any miscarriage (risk reduction. Low BMI (<20 nearly doubled the risk for SPTB-PPROM (odds ratio 2.64; 95% CI 1.07-6.51. The area under the receiver operating characteristics curve (AUC, after internal validation, was 0.69 for SPTB-IM and 0.79 for SPTB-PPROM. CONCLUSION: The ability to predict PTB in healthy nulliparous women using clinical characteristics is modest. The dissimilarity of risk factors for SPTB-IM compared with SPTB-PPROM indicates different pathophysiological pathways underlie these distinct phenotypes.

    Nulliparity is a major risk factor of preeclampsia investigated in numerous trials of its prevention. We aimed to assess whether these trials considered nulliparity in subject selection or analysis of results. 01 April 2013 search of MEDLINE via PubMed, EMBASE and the Cochrane Library. 01 April 2013 search of trials registered in Clinicaltrials.gov. Randomised controlled trials and metaanalyses of preeclampsia prevention with no restriction to period of publication or language. Metaanalyses were selected to fully identify relevant trials. One reader appraised each selected article/registered protocol using a pretested, standardized data abstraction form developed in a pilot test. For each article, he recorded whether both nulliparous and multiparous were included and, in case of mixed populations, whether randomisation was stratified, and whether subgroup analyses had been reported. For registered protocols, he only assessed whether it was planned to include mixed populations. 88 randomised controlled trials were identified, representing 83,396 included women. In 58 of the 88 articles identified (65.9%), preeclampsia was the primary outcome. In 31 of these (53.4%), the investigation combined nulliparous and multiparous women; only two reports in 31 (6.5%) stated that randomisation was stratified on parity and only four (12.9%) described a subgroup analysis by parity. Of the 30 registered trials, 20 (66.6%) planned to include both nulliparous and multiparous women. Parity is largely ignored in randomised controlled trials of preeclampsia prevention, which raises difficulties in interpreting the results.

    To compare between visual and computerized cardiotocography (cCTG) in low-risk pregnant women in predicting pregnancy outcome. One hundred and fifty-three consecutive computerized fetal heart tracings were recorded from non-laboring pregnant women at >/- 30 weeks gestation. All traces were reviewed by 2 experienced obstetricians. The study was carried out at Al-Ain Medical District, United Arab Emirates, between August 2004 and December 2004. Of the 153 pregnant women, 11 (7.2%) were delivered by cesarean section. The interobserver agreement was 0.60. The observers cCTG agreement were 0.48 and 0.45. The difference in cesarean section rate was not statistically significant. Observers interpretation and cCTG did not correlate well with Apgar score at 5 minutes and admission to special care baby unit. Computerized CTG has little advantage over conventional CTG in the prediction of Apgar score and need for neonatal intensive care unit admission in a low-risk population. (author)

    A study of the effectiveness and complications associated with the Model 200 copper T intrauterine device in 471 nulliparous women ranging in age from 14-33 years is reported, including 6044 woman-months of device use. 128 of the patients had had 1 or more previous abortions. This T-shaped device is made of polyethylene impregnated with barium sulfate, wound with .2 mm diameter copper wire providing a copper surface area of 200 square mm, and is inserted easily without anesthesia and with minimal pain. Continuation and failure rates were calculated for the first 12 months of use by life-table analysis. The overall continuation rate of device use was 74.2 per 100 women, the expulsion rate was 5.4, removal rate for bleeding or pain was 10.7, and pregnancy failure occurred at a rate of 1.7 per 100 women per year. These discontinuation event rates are lower than those reported for other IUDs in nulliparous women and comparable to IUD rates in multiparas. In the past, other IUD designs have been very unsatisfactory in nulliparas because of high expulsion and removal rates, but this study indicates that the TCu 200 IUD model is well accepted by nulliparas with good safety and effectiveness, and provides a promising and highly desired contraceptive alternative to oral contraception for young women.

  2. Cocaine Sensitization Increases Kyphosis and Modulates Neural Activity in Adult Nulliparous Rats

    Full Text Available Although data from both animals and humans suggests that adult cocaine use can have long term effects on behavior, it is unknown if prior cocaine use affects future maternal behavior in nulliparous females. In the current study, cocaine or saline was administered to adult female rats for 10 days, the animals were withdrawn from cocaine for 7 days, and the females were then exposed to donor pups to induce the expression of maternal behavior. Nulliparous females sensitized to cocaine were more likely to retrieve pups, spent more time caring for the pups, and were more likely to express full maternal behavior on day 8 of pup exposure. The fMRI data revealed significant effects of pup exposure in the hippocampal CA1 region, and effects of cocaine in the anterior thalamus and periaqueductal gray. Prior adult cocaine use may have lasting effects on offspring care, and this effect is not dependent on pup mediated effects or the endocrine changes of gestation and lactation. The present findings provide support for the hypothesis that maternal motivation to exhibit maternal behavior is enhanced by prior cocaine sensitization, possibly due to cross sensitization between cocaine and the natural reward of maternal behavior.

    To compare pelvic floor muscle strength in nulliparous sports students measured using the modified Oxford Grading Scale and a Peritron manometer; and to compare the manometric measurements between continent and incontinent subjects. Cross-sectional study. All subjects were evaluated twice on the same day; first by vaginal digital examination and subsequently by vaginal pressure using a Peritron manometer. Forty-three nulliparous female sports students [mean age 21 (standard deviation 4) years] from the Sports Faculty of the University of Porto. This study found a significant moderate correlation between the Oxford Grading Scale score and peak pressure on manometry (r=0.646, P=0.002). Mean maximal strength for the entire group was 70.4cmH2O (range 21 to 115cmH2O). Out of 43 subjects, 37% (n=16) demonstrated signs of incontinence. On manometry, no significant differences were found in vaginal resting pressure or peak pressure between the continent and incontinent groups. There was moderate correlation between peak pressure on manometry and the Oxford Grading Scale score. Peritron manometer measurements of pelvic floor muscle contractions showed no significant differences in vaginal resting pressure and peak pressure in continent and incontinent subjects.

    This paper recommends the establishment of specific design guidelines for protection against potential, but low-probability, energetic events. These guidelines recognize the plant protective features incorporated to prevent such events, as well as the inherent capability of the plant to accommodate a certain level of energy release. Further, their application is recommended within the context of necessary standardized and agreed-upon acceptance criteria which are less restrictive than ASME code requirements. The paper provides the background upon which the selection of the design is made, including the characterization of energetic events dependent on various core-design parameters, and including the necessity of a low-risk design balanced between prevention of accidents and the mitigation of consequences

    Full Text Available BACKGROUND Pelvic organ prolapse is a common complaint in gynaecological practice. Nulliparous prolapse is seen in 2% of female population and vault prolapse in 0.5% following hysterectomy. Various surgical procedures have been described for the repair of vault prolapse e.g. transvaginal sacrospinous colpopexy, transabdominal sacral colpopexy, Le Forte's operation, colpoclesis, posterior intravaginal sling plasty etc. The introduction of synthetic mesh like Prolene, Mersilene for the repair of vault prolapse have the advantage of tensile strength. In nulliparous prolapse and uterovaginal prolapse also, the supports of uterus are weakened, so there seems to be a definite advantage of mesh repair over sling surgeries. MATERIALS AND METHODS A prospective study done in 50 patients with vault prolapse, Nulliparous prolapse and patients with UV prolapse who want to retain their menstrual and reproductive function were identified and repair of defects were done. 2 cases who underwent both hysterectomy and sacral colpopexy in two sittings were included in the study. They were followed up for a period of 6 weeks - 29 months. RESULTS In the present study, the mean age for vault prolapse was 52.14 years, mean parity was 3.36. Vault prolapses were found to be more common after abdominal hysterectomy 60.97% compared to vaginal 39.02%. Common indication for hysterectomy is pelvic organ prolapse followed by DUB in this study. The mean time between the hysterectomy and vault prolapse in this study was 5.46 years. Importance should be given to proper enterocoele repair and vault suspense time of primary surgery. In this study incidence of smoking in vault prolapse cases was 34.14% significant. In cases of sacral colpopexy for vault prolapse in this study there were no major mesh related complications and the cure rate was 97.5%. So, sacral colpopexy with prolene mesh i.e. abdominal mesh repair can be employed as the primary surgery for vault prolapse. The safety

    Recently, several epidemiologic studies reported that lithium in drinking water may be associated with lower rates of suicide mortality at the population level, but other studies failed to confirm the association. The objective of the present study is to determine whether lithium in drinking water is associated with lower suicide rate after adjustment of potential confounding factors. From 2010 to 2013, 274 mean lithium levels of 434 lithium samples in drinking water were examined in relation to suicide standardized mortality ratios (SMRs) in 274 municipalities of Kyushu Island in Japan. Weighted least squares regression analysis adjusted for the size of each population was used to investigate the association of lithium levels with suicide SMRs. The associations of lithium levels in drinking water with suicide SMRs (total, male, and female) were investigated adjusting for proportion of elderly people, proportion of 1-person households, proportion of people with college education or more, and proportion of people engaging in primary industry (adjusted model 1), and further adjustment was performed with overall unemployment rate, annual marriage rate, annual mean temperature, and annual postal savings per person (adjusted model 2). Lithium levels in drinking water were significantly (β = -.169, P = .019) and inversely associated with male suicide SMRs but not total or female SMRs in the adjusted model 2. The present findings suggest that lithium in drinking water may be associated with the low risk of male suicide in the general population. Further studies are required to confirm these findings and investigate gender differences. © Copyright 2015 Physicians Postgraduate Press, Inc.

    Are parity and the timing of menarche associated with premature and early natural menopause? Early menarche (≤11 years) is a risk factor for both premature menopause (final menstrual period, FMP menopause (FMP 40-44 years), a risk that is amplified for nulliparous women. Women with either premature or early menopause face an increased risk of chronic conditions in later life and of early death. Findings from some studies suggest that early menarche and nulliparity are associated with early menopause, however overall the evidence is mixed. Much of the evidence for a direct relationship is hampered by a lack of comparability across studies, failure to adjust for confounding factors and inadequate statistical power. This pooled study comprises 51 450 postmenopausal women from nine observational studies in the UK, Scandinavia, Australia and Japan that contribute to the International collaboration for a Life course Approach to reproductive health and Chronic disease Events (InterLACE). Age at menarche (categorized as ≤11, 12, 13, 14 and 15 or more years) and parity (categorized as no children, one child and two or more children) were exposures of interest. Age at FMP was confirmed by at least 12 months of cessation of menses where this was not the result of an intervention (such as surgical menopause due to bilateral oophorectomy or hysterectomy) and categorized as premature menopause (FMP before age 40), early menopause (FMP 40-44 years), 45-49 years, 50-51 years, 52-53 years and 54 or more years. We used multivariate multinomial logistic regression models to estimate relative risk ratio (RRR) and 95% CI for associations between menarche, parity and age at FMP adjusting for within-study correlation. The median age at FMP was 50 years (interquartile range 48-53 years), with 2% of the women experiencing premature menopause and 7.6% early menopause. Women with early menarche (≤11 years, compared with 12-13 years) were at higher risk of premature menopause (RRR 1

    Objectives To evaluate the impact of maternal BMI on intrapartum interventions and adverse outcomes that may influence choice of planned birth setting in healthy women without additional risk factors. Design Prospective cohort study. Setting Stratified random sample of English obstetric units. Sample 17 230 women without medical or obstetric risk factors other than obesity. Methods Multivariable log Poisson regression was used to evaluate the effect of BMI on risk of intrapartum interventions and adverse maternal and perinatal outcomes adjusted for maternal characteristics. Main outcome measures Maternal intervention or adverse outcomes requiring obstetric care (composite of: augmentation, instrumental delivery, intrapartum caesarean section, general anaesthesia, blood transfusion, 3rd/4th degree perineal tear); neonatal unit admission or perinatal death. Results In otherwise healthy women, obesity was associated with an increased risk of augmentation, intrapartum caesarean section and some adverse maternal outcomes but when interventions and outcomes requiring obstetric care were considered together, the magnitude of the increased risk was modest (adjusted RR 1.12, 95% CI 1.02–1.23, for BMI > 35 kg/m2 relative to low risk women of normal weight). Nulliparous low risk women of normal weight had higher absolute risks and were more likely to require obstetric intervention or care than otherwise healthy multiparous women with BMI > 35 kg/m2 (maternal composite outcome: 53% versus 21%). The perinatal composite outcome exhibited a similar pattern. Conclusions Otherwise healthy multiparous obese women may have lower intrapartum risks than previously appreciated. BMI should be considered in conjunction with parity when assessing the potential risks associated with birth in non-obstetric unit settings. PMID:24034832

    One of the most important decisions that women have to make after becoming pregnant concerns their mode of birth, and these decisions are influenced by complex physiological, psychological and socio-cultural factors. To obtain in-depth descriptions of nulliparous women's experiences during the decision-making process for their mode of birth and to reveal their beliefs, attitudes and values. This is a qualitative, phenomenological study that included 29 nulliparous women. Data were collected using semi-structured, face-to-face interviews and analysed using the constant comparison method and guidelines developed by Collaizi. The women's experiences during their decision-making process for their mode of birth were placed into one of four categories, "getting confused", "no matter what happens", "others influencing women's decisions" and "make a decision one way or the other". Vaginal births were considered under the theme "natural but hard way" and caesarean sections under the theme "easy choice". The women indicated that they wanted to have vaginal births, but that they were not offered knowledge and support about modes of birth from health care professionals and, as a result, they asked their relatives for support. It is important to obtain pregnant women's preferences for modes of birth so that knowledge, support and care can be provided and so that they can be involved in the decision-making process. Therefore, health care professionals should understand pregnant women's experiences during the decision-making process for their mode of birth. Copyright © 2016 Australian College of Midwives.

    While many women report urinary incontinence (UI) during pregnancy, associations with pre-pregnancy urinary leakage remain under-explained. We performed a multi-strand prospective cohort study with 860 nulliparous women recruited during pregnancy. Prevalence of any urinary leakage was 34.8% before and 38.7% during pregnancy. Prevalence of UI, leaking urine at least once per month, was 7.2% and 17.7% respectively. Mixed urinary incontinence (MUI) was reported by 59.7% of women before and 58.8% during pregnancy, stress urinary incontinence (SUI) by 22.6% and 37.2%, and urge urinary incontinence (UUI) by 17.7% and 4.0%, respectively. SUI accounted for half (50.0%), MUI for less than half (44.2%), and UUI for 5.8% of new-onset UI in pregnancy. Pre-pregnancy UI was significantly associated with childhood enuresis [adjusted odds ratio (AOR) 2.9, 95% confidence interval (CI) 1.5-5.6, p = 0.001) and a body mass index (BMI) ≥30 kg/m 2 (AOR 4.2, 95% CI 1.9-9.4, p pregnancy BMI was 25-29.99 kg/m 2 (AOR 2.0, 95% CI 1.2-3.5, p = 0.01), and women who leaked urine less than once per month (AOR 2.6, 95% CI 1.6-4.1, p  pregnancy. Considerable proportions of nulliparous women leak urine before and during pregnancy, and most ignore symptoms. Healthcare professionals have several opportunities for promoting continence in all pregnant women, particularly in women with identifiable risk factors. If enquiry about UI, and offering advice on effective preventative and curative treatments, became routine in clinical practice, it is likely that some of these women could become or stay continent.

    OBJECTIVE: To examine the associations between extremes of maternal age (≤17 years or ≥40 years) and delivery outcomes. DESIGN: Retrospective cohort study. SETTING: Urban maternity hospital in Ireland. POPULATION: A total of 36 916 nulliparous women with singleton pregnancies who delivered between 2000 and 2011. METHODS: The study population was subdivided into five maternal age groups based on age at first booking visit: ≤17 years, 18-19 years, 20-34 years, 35-39 years and women aged ≥40 years. Logistic regression analyses were performed to examine the associations between extremes of maternal age and delivery outcomes, adjusting for potential confounding factors. MAIN OUTCOME MEASURES: Preterm birth, admission to the neonatal unit, congenital anomaly, caesarean section. RESULTS: Compared with maternal age 20-34 years, age ≤17 years was a risk factor for preterm birth (adjusted odds ratio [adjOR] 1.83, 95% confidence interval [95% CI] 1.33-2.52). Babies born to mothers ≥40 years were more likely to require admission to the neonatal unit (adjOR 1.35, 95% CI 1.06-1.72) and to have a congenital anomaly (adjOR 1.71, 95% CI 1.07-2.76). The overall caesarean section rate in nulliparous women was 23.9% with marked differences at the extremes of maternal age; 10.7% at age ≤17 years (adjOR 0.46, 95% CI 0.34-0.62) and 54.4% at age ≥40 years (adjOR 3.24, 95% CI 2.67-3.94). CONCLUSIONS: Extremes of maternal age need to be recognised as risk factors for adverse delivery outcomes. Low caesarean section rates in younger women suggest that a reduction in overall caesarean section rates may be possible.

    Full Text Available This study reported the effects of prostaglandin (PGF2a administration 10 days apart on reproductive parameters of cyclic artificial inseminated (AI nulliparous Alpine (n=9 and Saanen (n=9 goats. Animals received two doses of 22.5mg PGF2a 10 days apart. After 1st and 2nd PGF2a administrations, estrus was monitored at 12 h intervals, with a buck teaser. Plasma progesterone concentration (ng/mL was determined from blood sampled on day 0 (1st PGF2a and the following 5, 10 (2nd PGF2a, 15, 20, 25 and 30 days. After the onset of the second estrus, females were transrectally (5 MHz probe scanned at 4 hour intervals until at least 8h after ovulation. Pregnancy was checked through transrectal ultrasound on days 20, 25, 30, 35 and 90 after insemination. All parameters studied did not differ between breeds (P>0.05. Estrous response and interval to estrus, respectively, after 1st (78.9% and 50.6±17.2h and 2nd PGF2a (88.9% and 50.0±14.8h administration did not differ (P>0.05. Overall animals ovulating (100.0%, interval to ovulation after 2nd PGF2a (64.5±19.5h and after estrous onset (18.0±9.1h, ovulation rate (1.3±0.5, diameter of ovulatory follicle (8.1±1.1mm were recorded. Embryo loss occurred before day 30 of pregnancy. Estrus can be efficiently synchronized in nulliparous Alpine and Saanen goats with two doses of prostaglandin 10 days apart.

    Full Text Available Background & aim: Sexual activity is one of the most important aspects of a marital life. Childbirth is also a major event in the life of women, and the period of postpartum is a time of emotional upheaval. Since women believe that vaginal delivery could negatively affect their sexual function after childbirth, they tend to give birth through caesarean section. Therefore, this study aimed to evaluate the relationship between mode of delivery and sexual function in nulliparous women referred to healthcare centers in Mashhad, Iran. Methods: This correlational study was conducted on 450 nulliparous women, divided into two groups of vaginal delivery and cesarean section in 2014. Suubjects were selected via multistage sampling. Data collection tools included Female Sexual Function Index (FSFI, Depression, Anxiety and Stress scale (DASS-21, and Cassidy social support scale. Data was analyzed in SPSS version 16 using Spearman correlation coefficient and Mann-Whitney test, T-test, ANOVA, and Kruskal-Wallis. Moreover, general linear model was used to control confounding variables, and P-value of less than 0.05 was considered statistically significant. Results: Independent t-test results indicated that mean scores of sexual function in two groups of the study were 26.11±4.36 and 26.38±4.41, respectively, which revealed no statistically significant difference between the groups (P=0.509. Conclusion: No significant difference was observed between the vaginal delivery and caesarean section groups regarding sexual function. Therefore, it seems that cesarean section does not necessarily lead to pleasing sexual relationships in postpartum period compared to vaginal delivery.

  2. Mixing nulliparous and multiparous women in randomised controlled trials of preeclampsia prevention is debatable: evidence from a systematic review.

    Emmanuel Simon

    Full Text Available BACKGROUND: Nulliparity is a major risk factor of preeclampsia investigated in numerous trials of its prevention. OBJECTIVE: We aimed to assess whether these trials considered nulliparity in subject selection or analysis of results. SEARCH STRATEGY: 01 April 2013 search of MEDLINE via PubMed, EMBASE and the Cochrane Library. 01 April 2013 search of trials registered in Clinicaltrials.gov. SELECTION CRITERIA: Randomised controlled trials and metaanalyses of preeclampsia prevention with no restriction to period of publication or language. Metaanalyses were selected to fully identify relevant trials. DATA COLLECTION AND ANALYSIS: One reader appraised each selected article/registered protocol using a pretested, standardized data abstraction form developed in a pilot test. For each article, he recorded whether both nulliparous and multiparous were included and, in case of mixed populations, whether randomisation was stratified, and whether subgroup analyses had been reported. For registered protocols, he only assessed whether it was planned to include mixed populations. MAIN RESULTS: 88 randomised controlled trials were identified, representing 83,396 included women. In 58 of the 88 articles identified (65.9%, preeclampsia was the primary outcome. In 31 of these (53.4%, the investigation combined nulliparous and multiparous women; only two reports in 31 (6.5% stated that randomisation was stratified on parity and only four (12.9% described a subgroup analysis by parity. Of the 30 registered trials, 20 (66.6% planned to include both nulliparous and multiparous women. CONCLUSION: Parity is largely ignored in randomised controlled trials of preeclampsia prevention, which raises difficulties in interpreting the results.

    Full Text Available Background & aim: The enhancement of childbirth self-efficacy to manage the labor pain can help the nulliparous pregnant women to make informed choice about vaginal delivery. Regarding the relationship of the childbirth self-efficacy with psychological antecedents, the present study aimed to explore the meditating role of alexithymia in the relationship of attachment styles and childbirth self-efficacy among the nulliparous pregnant women. Methods: This descriptive correlational study was conducted on 210 nulliparous pregnant women, living in Shiraz in 2016. The samples were selected from the nulliparous women referring to the public and private health and medical centers through the purposive sampling technique. The data were collected using a researcher-made demographic form, Iranian version of Childbirth Self-Efficacy Inventory, Hazan and Shaver’s Adult Attachment Inventory, and Farsi Toronto Alexithymia Scale-20. The data analysis was performed using the descriptive statistics and structural equation modeling through the SPSS version 20 and AMOS version 21, respectively. Results: Our findings indicated that all aspects of attachment styles (i.e., secure, avoidant, and ambivalent would be able to predict the childbirth self-efficacy in the nulliparous pregnant women. On the other hand, the secure and insecure attachment styles predicted alexithymia among this population. The results of the path analysis demonstrated that alexithymia had a mediating role in the relationship of the attachment styles and the childbirth self-efficacy. Conclusion: Based on the findings of the present study, it can be concluded that the attachment styles and childbirth self-efficacy had an indirect relationship mediating through such variables as alexithymia.

    Full Text Available >Background and Aim: Epidural analgesia (EA offers an effective form of labour analgesia. The time of administration of EA and its relationship with the mode of delivery is controversial. Our study tried to assess whether early initiation of epidural analgesia influences the obstetric outcome in nulliparous women.Materials and Methods: This was a case control, randomised study which included 60 parturients in spontaneous labour divided into two equal groups, the cases and controls. Cases received EA with 10 mL of 0.125% injection bupivacaine, whereas the control group received a systemic opioid (injection pethidine 100 mg intramuscularly for pain relief. Cases were further divided into parturients receiving EA at a cervical dilatation of 3 cm or less classified as the early epidural group and those receiving EA at 4 cm or more classified as the late epidural group. The modes of delivery for the study population were recorded. Data analysis was done using Wilcoxon two-sample test. P < 0.05 was considered statistically significant.Results: The rate of instrumental vaginal delivery between the early epidural group [95% confidence interval (CI 0.358–10.821; P = 0.43] and late epidural group (95% CI 0.150–6.055; P = 0.96 was not significantly different. The cesarean-delivery rate was also not significantly different between those receiving early EA (P = 0.95 and late EA (P = 0.58 when compared with control group.Conclusion: This study showed no significant difference in the incidence of caesarean or instrumental delivery for women receiving early epidural analgesia when compared with late epidurals or no EA.

    To perform pelvimetry in nulliparous and primiparous women using 3 Tesla magnetic resonance imaging (3T MRI). Twenty-five nulliparous volunteers and 25 primiparous women underwent pelvic 3T MRI within one week after vaginal childbirth in a prospective clinical single-center trial. The pelvimetric parameters interspinous distance (ISD), intertuberous distance (ITD), sagittal outlet (SO), obstetric conjugate (OC), and coccygeal curved length (CCL) were adapted from anthropometric measurements as well as from sonographic and computed tomography-based pelvimetry performed on high-resolution T2-weighted images. We compared the results of the two study groups to one another, recent literature and postpartum-diagnosed levator ani muscle (LAM) injuries. The mean values for primipara/nullipara were ISD 107 ± 8.3/105 ± 8.4 mm, ITD 119.8 ± 10.2/118.4 ± 13.1 mm, OC 129.4 ± 10/130.8 ± 6.9 mm, SO 114.3 ± 7.8/112.5 ± 8.9 mm, and CCL 37.3 ± 7.4/39 ± 8 mm. Significant differences (P < 0.05) were found between the results for OC, SO, and CCL (primipara) and ISD, ITD and OC (nullipara) and the values in the literature. No significant difference in pelvimetric values was found between the groups. A significant correlation was found between the pelvimetric parameters and five types of LAM injuries. Two-dimensional 3T MRI combines high-resolution images with objective pelvimetric measurements applicable in a postpartum setting. Our results provide a good foundation for further MRI-based studies evaluating the bony pelvis and its relation to LAM injuries during vaginal childbirth. © 2018 Wiley Periodicals, Inc.

    Full Text Available Abstract Background The increasing prevalence of obesity in young women is a major public health concern. These trends have a major impact on pregnancy outcomes in these women, which have been documented by several researchers. In a population based cohort study, using routinely collected data, this paper examines the effect of increasing Body Mass Index (BMI on pregnancy outcomes in nulliparous women delivering singleton babies. Methods This was a retrospective cohort study, based on all nulliparous women delivering singleton babies in Aberdeen between 1976 and 2005. Women were categorized into five groups – underweight (BMI 2, normal (BMI 20 – 24.9 Kg/m2 overweight (BMI 25 – 29.9 Kg/m2, obese (BMI 30 – 34.9 Kg/m2 and morbidly obese (BMI > 35 Kg/m2. Obstetric and perinatal outcomes were compared by univariate and multivariate analyses. Results In comparison with women of BMI 20 – 24.9, morbidly obese women faced the highest risk of pre-eclampsia {OR 7.2 (95% CI 4.7, 11.2} and underweight women the lowest {OR 0.6 (95% CI 0.5, 0.7}. Induced labour was highest in the morbidly obese {OR 1.8 (95% CI 1.3, 2.5} and lowest in underweight women {OR 0.8 (95% CI 0.8, 0.9}. Emergency Caesarean section rates were highest in the morbidly obese {OR 2.8 (95% CI 2.0, 3.9}, and comparable in women with normal and low BMI. Obese women were more likely to have postpartum haemorrhage {OR 1.5 (95% CI 1.3, 1.7} and preterm delivery ( 4,000 g was in the morbidly obese {OR 2.1 (95% CI 1.3, 3.2} and the lowest in underweight women {OR 0.5 (95% CI 0.4, 0.6}. Conclusion Increasing BMI is associated with increased incidence of pre-eclampsia, gestational hypertension, macrosomia, induction of labour and caesarean delivery; while underweight women had better pregnancy outcomes than women with normal BMI.

    Background Long-acting reversible contraceptive (LARC) methods, including intrauterine devices (IUDs) and the contraceptive implant, are considered the best methods for preventing unintended pregnancies, rapid repeat pregnancy, and abortion in young women. An opinion paper of 2012 by the American College of Obstetricians and Gynecologists recommends Mirena and Paragard for use in nulliparous and adolescent women. However, these IUDs are not designed for young women and are not optimal as they often lead to early discontinuation. Objective This article was written with the objective to respond to the urgent need to improve intrauterine contraception as it is likely that the objectives of LARC will not be met without significant improvement of IUD design. Anatomical variations in size and shape of the uterus are not sufficiently considered, producing harm and suffering, which often lead to early removal of the IUD. Proposed problem solving The article describes why IUDs should be revisited to meet the challenge of LARC and proposes how to solve these problems. The opinion statement presented here may be considered provocative but is based on hundreds of women with IUD problems who consult or are referred to the practices of the authors of this article due to the disproportion between the IUD and their small uterine cavity. The solution is simple but requires a revision of the current design of IUDs. One-dimensional (longitudinal) IUDs are likely to be the first option. Framed devices with shortened transverse arm and IUDs which adapt to the width of the given uterus are viewed as second best. Conclusion One of the reasons of the high unintended pregnancy rate in the USA may be the paucity of suitable IUDs. Also, the legal climate in the USA seems to be a problem for developers as many lawsuits have recently been reported. Clinical studies conducted in young nulliparous and adolescent women suggest that IUDs that fit well in the uterine cavity, like a shoe, result in

    Obesity is increasing among primipara women. We aimed to describe the association between body mass index (BMI) during early-pregnancy and duration of labour in nulliparous women. Retrospective observational cohort study of 1885 nulliparous women with a single cephalic presentation from 37 0/7 to 42 6/7 weeks of completed gestation and spontaneous or induced labour at Nordsjællands Hospital, University of Copenhagen, Denmark, in 2011 and 2012. Total duration of labour and the first and second stages of labour were compared between early-pregnancy normal-weight (BMI <25 kg/m 2 ), overweight (BMI 25-29.9 kg/m 2 ), and obese (BMI ≥30 kg/m 2 ) women. Proportional hazards and multiple logistic regression models were applied. Early pregnancy BMI classified 1246 (66.1%) women as normal weight, 350 (18.6%) as overweight and 203 (10.8%) as obese. No difference in the duration of total or first stage of active labour was found for overweight (adjusted HR = 1.01, 95% CI 0.88-1.16) or obese (adjusted HR = 1.07, 95% CI 0.90-1.28) compared to normal weight women. Median active labour duration was 5.83 h for normal weight, 6.08 h for overweight and 5.90 h for obese women. The risk of caesarean delivery increased significantly for overweight and obese compared to normal weight women (odds ratios (OR) 1.62; 95%CI 1.18-2.22 and 1.76; 95%CI 1.20-2.58, respectively). Caesarean deliveries were performed earlier in labour in obese than normal-weight women (HR = 1.80, 95%CI 1.28-2.54). BMI had no significant effect on total duration of active labour. Risk of caesarean delivery increased with increasing BMI. Caesarean deliveries are undertaken earlier in obese women compared to normal weight women following the onset of active labour, shortening the total duration of active labour.

    Full Text Available Abstract Background Increasing rates of postpartum haemorrhage in developed countries over the past two decades are not explained by corresponding changes in risk factors and conjecture has been raised that maternal obesity may be responsible. Few studies investigating risk factors for PPH have included BMI or investigated PPH risk among nulliparous women. The aim of this study was to determine in a cohort of nulliparous women delivering at term whether overweight and obesity are independent risk factors for major postpartum haemorrhage (PPH ≥1000ml after vaginal and caesarean section delivery. Methods The study population was nulliparous singleton pregnancies delivered at term at National Women’s Hospital, Auckland, New Zealand from 2006 to 2009 (N=11,363. Multivariable logistic regression was adjusted for risk factors for major PPH. Results There were 7238 (63.7% women of normal BMI, 2631 (23.2% overweight and 1494 (13.1% obese. Overall, PPH rates were increased in overweight and obese compared with normal-weight women (n=255 [9.7%], n=233 [15.6%], n=524 [7.2%], p Conclusion Nulliparous obese women have a twofold increase in risk of major PPH compared to women with normal BMI regardless of mode of delivery. Higher rates of PPH among obese women are not attributable to their higher rates of caesarean delivery. Obesity is an important high risk factor for PPH, and the risk following vaginal delivery is emphasised. We recommend in addition to standard practice of active management of third stage of labour, there should be increased vigilance and preparation for PPH management in obese women.

    Full Text Available Background This study was performed to compare changes in urinary incontinence (UI symptoms and pelvic floor structure during pregnancy between nulliparous and multiparous women. Methods A cross-sectional survey was performed among pregnant women from July 2016 to January 2017. In total, 358 pregnant women from two hospitals underwent an interview and pelvic floor transperineal ultrasound assessment. A questionnaire regarding sociodemographic, gynecological, obstetric features and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF were used for the interview. Imaging data sets were analyzed offline to assess the bladder neck vertical position (BNVP, urethral angles (α, β, and γ angles, and hiatal area (HA at rest and at maximal Valsalva maneuver (VM. Results After excluding 16 women with invalid data, 342 women were included. The prevalence (χ2 = 9.15, P = 0.002, frequency (t = 2.52, P = 0.014, usual amount of UI (t = 2.23, P = 0.029 and scores of interference with daily life (t = 2.03, P = 0.045 during pregnancy were higher in multiparous than nulliparous women. A larger bladder neck descent (BND (F = 4.398, P < 0.001, HA (F = 6.977, P < 0.001, α angle (F = 2.178, P = 0.030, β angle (F = 4.404, P < 0.001, and γ angle (F = 2.54, P = 0.011 at VM were discovered in pregnant women with UI than without UI. Multiparous women had a significantly higher BND (t = 2.269, P = 0.024 and a larger α angle (F = 2.894, P = 0.004, β angle (F = 2.473, P = 0.014, and γ angle (F = 3.255, P = 0.001 at VM than did nulliparous women. Conclusion Multiparous women experienced more obvious UI symptoms and pelvic floor structure changes during pregnancy than did nulliparous women.

    Full Text Available Objective. To identify the potential effect of ethnic variation on the success of induction of labour in nulliparous women with postdates pregnancies. Study Design. This was an observational cohort study of women being induced for postdates pregnancies (≥41 weeks between 2007 and 2013. Women induced for stillbirths and with multiple pregnancies were excluded. The primary objective was to identify the effect of ethnicity on the caesarean section (CS delivery rates in this cohort of women. Results. 1,636 nulliparous women were identified with a mean age of 27.2 years. 95.8% of the women were of White ethnic origin, 2.6% were Asian, and 1.6% were of Black ethnic origin. The CS delivery rate was 24.4% in the total sample. Women of Black ethnic origin had a 3.26 times greater likelihood for CS in comparison to White women, after adjusting for maternal age, BMI, smoking, presence of meconium, use of epidural analgesia, fetal gender, birth weight, and head circumference (adjusted OR = 3.26; 95% CI: 1.31–8.08, p = 0.011. Conclusion. We have found that nulliparous women of Black ethnicity demonstrate an almost threefold increased risk of caesarean section delivery when induced for postdates pregnancy.

    Worldwide induction and cesarean delivery rates have increased rapidly, with consequences for subsequent pregnancies. The majority of intrapartum cesarean deliveries are performed for failure to progress, typically in nulliparous women at term. Current uterine registration techniques fail to identify inefficient contractions leading to first-stage labor arrest. An alternative technique, uterine electromyography has been shown to identify inefficient contractions leading to first-stage arrest of labor in nulliparous women with spontaneous onset of labor at term. The objective of this study was to determine whether this finding can be reproduced in induction of labor. Uterine activity was measured in 141 nulliparous women with singleton term pregnancies and a fetus in cephalic position during induced labor. Electrical activity of the myometrium during contractions was characterized by its power density spectrum. No significant differences were found in contraction characteristics between women with induced labor delivering vaginally with or without oxytocin and women with arrested labor with subsequent cesarean delivery. Uterine electromyography shows no correlation with progression of labor in induced labor, which is in contrast to spontaneous labor. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Introduction: To quantify the distribution of morphologic appearances of urethral anatomy and measure variables of urethral sphincter anatomy in continent, nulliparous, pregnant women by high resolution magnetic resonance imaging (MRI). Materials and methods: We studied fifteen women during their first pregnancy. We defined and quantified bladder neck and urethral morphology on axial and sagittal MR images from healthy, continent women. Results: The mean (±standard deviation) total transverse urethral diameter, anterior–posterior diameter, unilateral striated sphincter muscle thickness, and striated sphincter length were 15 ± 2 mm (range: 12–19 mm), 15 ± 2 mm (range: 11–20 mm), 2 ± 1 mm (range: 1–4 mm), and 13 ± 3 mm (range: 9–18 mm) respectively. The mean (±standard deviation) total urethral length on sagittal scans was 22 ± 3 mm (range: 17.6–26.4 mm). Discussion: Advances in MR technique combined with anatomical and histological findings will provide an insight to understand how changes in urethral anatomy might affect the continence mechanisms in pregnant and non-pregnant, continent or incontinent individuals.

    Few studies have examined associations of prepregnancy urinary incontinence (UI). Multicentre prospective pregnancy cohort study (n = 1,507) using standardised measures to assess frequency and severity of UI. Prevalence of UI increased from 10.8% in the 12 months before the index pregnancy to 55.9% in the third trimester. Stress incontinence (36.9%) and mixed incontinence (13.1%) were more common during pregnancy than urge incontinence alone (5.9%). UI before pregnancy was associated with childhood enuresis (adjusted odds ratio (AdjOR) = 2.4, 95% confidence interval (CI) 1.6-3.4), higher maternal body mass index (AdjOR = 2.3, 95% CI 1.4-3.8), and previous miscarriages or terminations (AdjOR = 1.6, 95% CI 1.1-2.3). The strongest predictor of incident UI in pregnancy was occasional leakage (less than once a month) before pregnancy (AdjOR = 3.6, 95% CI 2.8-4.7). Further research is needed to elucidate the complex interplay of prepregnancy and pregnancy-related factors in the aetiology of UI in nulliparous women.

    Full Text Available Objective. Excessive gestational weight gain (GWG is associated with adverse maternal and child outcomes and contributes to obesity in women. Our aim was to identify early pregnancy factors associated with excessive GWG, in a contemporary nulliparous cohort. Methods. Participants in the SCOPE study were classified into GWG categories (“not excessive” versus “excessive” based on pregravid body mass index (BMI using 2009 Institute of Medicine (IOM guidelines. Maternal characteristics and pregnancy risk factors at 14–16 weeks were compared between categories and multivariable analysis controlled for confounding factors. Results. Of 1950 women, 17% gained weight within the recommended range, 74% had excessive and 9% inadequate GWG. Women with excessive GWG were more likely to be overweight (adjOR 2.9 (95% CI 2.2–3.8 or obese (adjOR 2.5 (95% CI 1.8–3.5 before pregnancy compared to women with a normal BMI. Other factors independently associated with excessive GWG included recruitment in Ireland, younger maternal age, increasing maternal birthweight, cessation of smoking by 14–16 weeks, increased nightly sleep duration, high seafood diet, recent immigrant, limiting behaviour, and decreasing exercise by 14–16 weeks. Fertility treatment was protective. Conclusions. Identification of potentially modifiable risk factors for excessive GWG provides opportunities for intervention studies to improve pregnancy outcome and prevent maternal obesity.

Teaching and research hospital. Ninety women of reproductive age eligible for diagnostic hysteroscopy. Randomly assignment to receive 400 μg of misoprostol (n = 30) or 10 mg of dinoprostone (n = 30) vaginally before diagnostic hysteroscopy, with a control group (n = 30) not receiving any cervical priming agent. the number of women requiring cervical dilatation; secondary outcomes: cervical width before surgery, duration of dilatation time, ease of dilatation, complications during surgical procedure, and side effects of the drugs. In the placebo group, 23 patients required cervical dilatation compared with 17 in the misoprostol group and 9 in the dinoprostone group. The mean (± standard deviation) cervical widths for the placebo, misoprostol, and dinoprostone groups were 4.23 ± 0.43 mm, 5.43 ± 0.5 mm, and 5.83 ± 0.64 mm, respectively. These widths were statistically significantly different. The duration of dilatation was also statistically significantly longer in the control group. Vaginally administered dinoprostone before diagnostic hysteroscopy is more effective than misoprostol for inducing cervical priming. Further studies are required to elucidate the most efficient option with the least side effects for cervical ripening. NCT01620814. Copyright © 2015 American Society for Reproductive Medicine.

    Synthetic oxytocin, the primary tool for labor augmentation, is less effective among obese women, leading to more unplanned cesarean deliveries for slow labor progress. It is not known if obese women require higher doses of oxytocin due to maternal, fetal, or labor factors related to maternal obesity. This study had two main objectives: (1) examine the influence of maternal body mass index (BMI) on hourly doses of oxytocin from augmentation initiation until vaginal delivery in obese women; and (2) examine the influence of other maternal, fetal, and labor factors on hourly doses of oxytocin in obese women. Longitudinal study of a cohort ( N = 136) of healthy, nulliparous, spontaneously laboring obese women (BMI ≥ 30 kg/m 2 ) who received oxytocin augmentation and achieved vaginal delivery. We performed iterative multilevel analyses to examine the influence of maternal BMI and other factors on hourly oxytocin doses. Maternal BMI explained 16.56% (95% confidence interval [CI] = [13.7, 20.04], p multilevel model controlling for influence of maternal, fetal, and labor characteristics. Maternal age, gestational age, status of amniotic membranes at hospital admission, and admission cervical dilation examination were not significant; however, neonatal birthweight and cervical dilation at oxytocin initiation were significant predictors of hourly oxytocin dose in these women ( p response to oxytocin used for augmentation.

    To record and characterize electromyography (EMG) from the uterus and abdominal muscles during the nonlabor to first and second stages of labor and to define relationships to contractions. Nulliparous patients without any treatments were used (n = 12 nonlabor stage, 48 during first stage and 33 during second stage). Electromyography of both uterine and abdominal muscles was simultaneously recorded from electrodes placed on patients' abdominal surface using filters to separate uterine and abdominal EMG. Contractions of muscles were also recorded using tocodynamometry. Electromyography was characterized by analysis of various parameters. During the first stage of labor, when abdominal EMG is absent, uterine EMG bursts temporally correspond to contractions. In the second stage, uterine EMG bursts usually occur at same frequency as groups of abdominal bursts and precede abdominal bursts, whereas abdominal EMG bursts correspond to contractions and are accompanied by feelings of "urge to push." Uterine EMG increases progressively from nonlabor to second stage of labor. (1) Uterine EMG activity can be separated from abdominal EMG events by filtering. (2) Uterine EMG gradually evolves from the antepartum stage to the first and second stages of labor. (3) Uterine and abdominal EMG reflect electrical activity of the muscles during labor and are valuable to assess uterine and abdominal muscle events that control labor. (4) During the first stage of labor uterine, EMG is responsible for contractions, and during the second stage, both uterine and abdominal muscle participate in labor.

    To assess the efficacy of heparin in preventing the abrupt closure after coronary angioplasty in low risk patients for this phenomenon. In the last 4 years, 525 patients successfully dilated were randomized to receive intravenous heparin (n = 264) or not (n = 261) after the angioplasty. The excluding criteria were contraindications for heparin and risk for abrupt closure (refractory unstable angina, primary coronary angioplasty in acute myocardial infarction, evidence of intracoronary thrombus, intimal tear after the procedure and cases of chronic total occlusions). Both heparin and non heparin groups were similar in respect to female sex (15% x 17%; p = NS), age over 70 years old (7% x 9%; p = NS), previous myocardial infarction (26% x 24%; p = NS), multi-vessel procedures (4% x 7%; p = NS, stable angina (40% x 46%; p = NS), unstable angina (52% x 48%; p = NS) and angioplasty after thrombolytic therapy (8% x 6%; p = NS). The overall incidence of abrupt closure was 2/525 (0.4%), with one case (0.4%) in each group. The in-hospital mortality was 1/525 (0.2%), which occurred in a non-heparin patient, due to a anterior myocardial infarction. Major complications occurred similarly in heparin and non-heparin groups (0.4%). Bleeding complications were observed more frequently in the heparin group (7% x 2%; p = 0.002). All of them were in the catheterization site and none required blood transfusion. Severe systemic bleeding were not observed. In patients regarded as low risk for abrupt closure, the incidence of this complication was really low (0.4%) and heparin probably do not prevent it.

    Active surveillance is a management strategy for men diagnosed with early-stage, low-risk prostate cancer in which their cancer is monitored and treatment is delayed. This study investigated the primary coping mechanisms for men following the active surveillance treatment plan, with a specific focus on how these men interact with their social network as they negotiate the stress and uncertainty of their diagnosis and treatment approach. Thematic analysis of semi-structured interviews at two academic institutions located in the northeastern US. Participants include 15 men diagnosed with low-risk prostate cancer following active surveillance. The decision to follow active surveillance reflects the desire to avoid potentially life-altering side effects associated with active treatment options. Men on active surveillance cope with their prostate cancer diagnosis by both maintaining a sense of control over their daily lives, as well as relying on the support provided them by their social networks and the medical community. Social networks support men on active surveillance by encouraging lifestyle changes and serving as a resource to discuss and ease cancer-related stress. Support systems for men with low-risk prostate cancer do not always interface directly with the medical community. Spousal and social support play important roles in helping men understand and accept their prostate cancer diagnosis and chosen care plan. It may be beneficial to highlight the role of social support in interventions targeting the psychosocial health of men on active surveillance.

    Dietary factors have been hypothesized to influence the risk of preeclampsia. The aim of this study was to investigate the association between maternal intake of sugar and foods with a high content of added or natural sugars and preeclampsia. A prospective study of 32,933 nulliparous women in the Norwegian Mother and Child Cohort Study, conducted by the Norwegian Institute of Public Health. Participants answered a general health questionnaire and a validated food frequency questionnaire during pregnancy. Information about preeclampsia was obtained from the Medical Birth Registry of Norway. The relative risk of preeclampsia was estimated as odds ratios (OR) and 95% confidence intervals (CIs) and adjusted for known confounders. The intake of added sugar was higher in women who developed preeclampsia than in healthy women in the unadjusted analysis, but not in the adjusted model. Of food items with a high content of added sugar, sugar-sweetened carbonated and non-carbonated beverages were significantly associated with increased risk of preeclampsia, both independently and combined, with OR for the combined beverages 1.27 (95% CIs: 1.05, 1.54) for high intake (> = 125 ml/day) compared with no intake. Contrary to this, intakes of foods high in natural sugars, such as fresh and dried fruits, were associated with decreased risk of preeclampsia. These results suggest that foods with a high content of added sugar and foods with naturally occurring sugars are differently associated with preeclampsia. The findings support the overall dietary advice to include fruits and reduce the intake of sugar-sweetened beverages during pregnancy.

    Full Text Available Abstract Background In the first year after childbirth, 94% of women experience one or more major health problems (urinary incontinence, faecal incontinence, perineal pain, back pain. Difficulties in intimate partner relationships and changes affecting sexual health are also common. The aim of this study is to investigate changes in women's health from early pregnancy until four years after the birth of a first child. Methods/design The Maternal Health Study is a longitudinal study designed to fill in some of the gaps in current research evidence regarding women's physical and psychological health and recovery after childbirth. A prospective pregnancy cohort of >1500 nulliparous women has been recruited in early pregnancy at six metropolitan public hospitals in Melbourne, Australia between April 2003 and December 2005. In the first phase of the study participants are being followed up at 30–32 weeks gestation in pregnancy, and at three, six, nine, 12 and 18 months postpartum using a combination of self-administered questionnaires and telephone interviews. Women consenting to extended follow-up (phase 2 will be followed up six and 12 months after any subsequent births and when their first child is four years old. Study instruments incorporate assessment of the frequency and severity of urinary and bowel symptoms, sexual health issues, perineal and abdominal pain, depression and intimate partner violence. Pregnancy and birth outcome data will be obtained by review of hospital case notes. Discussion Features of the study which distinguish it from prior research include: the capacity to identify incident cases of morbidity and clustering of health problems; a large enough sample to detect clinically important differences in maternal health outcomes associated with the method of birth; careful exposure measurement involving manual abstraction of data from medical records in order to explore mediating factors and possible causal pathways; and use of

    Full Text Available Preeclampsia is a hypertensive disorder of pregnancy causing a high rate of both maternal and neonatal morbidity and mortality. Recent reports suggest that free radical-induced endothelial cell injury might be an etiologic factor in the pathogenesis of preeclampsia. The aim of this study was to determine the effect of antioxidants such as E and C vitamins on the prevention of preeclampsia. Materials and Methods: This clinical- trial study was conducted in the year 2009 in the clinical centers of Lorestan university of medical sciences. 160 nulliparous women with the age range of 18 to 35 without any risk factors for preeclampsia were divided into two groups. The first group received oral vitamin E 400 IU/day, and vitamin C 1000 mg/day with iron tablets during the 20th to 24th weeks of pregnancy while the control group received only iron tablets. Finally, the data was analyzed using descriptive statistics and frequency distribution tables. Results: Incidence of preeclampsia in the control group was 17.5% and in the case group it was 5% that was statistically significant. The means of systolic pressure before and after intervention in the control group were 99.43 7.8, and 12.44 19.1 while in the case group they were 99.3 8.3 and 106.12 13.25. Diastolic pressure means before and after intervention in the control group were 62.7 13.6 and 62.7 4.7. Conclusion: As the results showed, use of antioxidants can clearly reduce the risk of preeclampsia, and can reduce the mean systolic and diastolic pressure.

    The future use of nuclear energy for electricity production is assumed as a viable alternative at present, mainly taking into account the high environmental impact of the fossil fuel alternatives (greenhouse effect, acid rain). In the worldwide context, however, it is desirable that the next generation of nuclear power stations to be safer than the present ones. To demonstrate the safety level of a particular nuclear installation, the Risk Analysis (or Probabilistic Safety Assessment) is the most appropriate tool. Quantitative risk estimations can be performed with PSA. The risk can be split as the product of two factors: the first one takes into account the occurrence probability of accidental sequences that involve the release of radioactive material, and the second takes into account the magnitude and consequences of such a release. In the present work, the reduction of both factors is analyzed. The probability is reduced by the use of simpler and more reliable systems to perform the safety functions, and the consequence by the use of small power production units, provided with passive mitigation systems and long response times. The work is illustrated with a risk comparison for electricity production with CAREM-25 units, towards classic production units (Atucha II). The results are based on PSAs performed for both plants. The conclusions show an effective risk reduction (both in probability and in consequence) for the innovative CAREM-25 plant, coming to doses so low as to prevent any acute effect in the nearby population.

    The purpose of the present studies was to investigate the activity of the adrenal gland and the pituitary {beta}-endorphin system in individuals from families with a 3 generation history of alcoholism, High Risk group, or from families without history of alcoholism, Low Risk group. On the day of testing, blood sample was taken at 9:00 a.m., then the subject drank a placebo drink or an ethanol solution. Additional blood samples were taken at 15, 45 and 120 minutes post-drink. Results indicated that individuals of the High Risk group had lower basal levels of {beta}-endorphin like immunoreactivity ({beta}-EPLIR) than individuals of the Low Risk group. The dose of 0.5 g ethanol/kg B.Wt. induced an induce an increase in the plasma content of {beta}-EPLIR of the High Risk group, but not of the Low Risk group. In the Low Risk group ethanol did not induce an increase above the 9:00 a.m. levels, however, it attenuated the {beta}-endorphin decrease overtime, observed following the placebo drink. Analysis of {beta}-endorphin-like peptides in the plasma of the High Risk group, with Sephadex G-75 chromatography indicated that the major component of the plasma {beta}-EPLIR was {beta}-lipotropin. Plasma cortisol levels, following ethanol intake, presented a small increase in the High Risk group but not in the Low Risk group.

    In contemporary practice many nulliparous women require intervention during childbirth such as operative vaginal delivery or cesarean delivery (CD). Despite the knowledge that the increasing rate of CD is associated with increasing maternal age, obesity and larger infant birthweight, we lack a reliable method to predict the requirement for such potentially hazardous obstetric procedures during labor and delivery. This issue is important, as there are greater rates of morbidity and mortality associated with unplanned CD performed in labor compared with scheduled CDs. A prediction algorithm to identify women at risk of an unplanned CD could help reduced labor associated morbidity. In this primary analysis of the Genesis study, our objective was to prospectively assess the use of prenatally determined, maternal and fetal, anthropomorphic, clinical, and ultrasound features to develop a predictive tool for unplanned CD in the term nulliparous woman, before the onset of labor. The Genesis study recruited 2336 nulliparous women with a vertex presentation between 39+0 and 40+6 weeks' gestation in a prospective multicenter national study to examine predictors of CD. At recruitment, a detailed clinical evaluation and ultrasound assessment were performed. To reduce bias from knowledge of these data potentially influencing mode of delivery, women, midwives, and obstetricians were blinded to the ultrasound data. All hypothetical prenatal risk factors for unplanned CD were assessed as a composite. Multiple logistic regression analysis and mathematical modeling was used to develop a risk evaluation tool for CD in nulliparous women. Continuous predictors were standardized using z scores. From a total enrolled cohort of 2336 nulliparous participants, 491 (21%) had an unplanned CD. Five parameters were determined to be the best combined predictors of CD. These were advancing maternal age (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.09 to 1.34), shorter maternal height (OR

    Full Text Available Objective The aim of this study was to assess pelvic floor muscle (PFM strength in different body positions in nulliparous healthy women and its correlation with sexual activity. Materials and Methods Fifty healthy nulliparous women with mean age of 23 years were prospectively studied. Subjective evaluation of PFM was assessed by transvaginal digital palpation (TDP of anterior and posterior areas regarding the vaginal introitus. A perineometer with inflatable vaginal probe was used to assess the PFM strength in four different positions: supine with extended lower limbs (P1; bent-knee supine (P2; sitting (P3; standing (P4. Results Physical activity, 3 times per week, was reported by 58% of volunteers. Sexual activity was observed in 80% of women and 82% of them presented orgasm. The average body mass index (BMI was 21.76 kg/m2, considered as normal according World Health Organization (WHO. We observed that 68% of volunteers were conscious about the PFM contraction. TDP showed concordance of 76% when anterior and posterior areas were compared (p = 0.00014. There was not correlation between PFM strength and orgasm in subjective evaluation. The PFM strength was significantly higher in standing position when compared with the other positions (p < 0.000. No statistical difference was observed between orgasm and PFM strength when objective evaluations were performed. Conclusions There was concordance between anterior and posterior areas in 76% of cases when subjective PFM strength was assessed. In objective evaluation, higher PFM strength was observed when volunteers were standing. No statistical correlation was observed between PFM strength and orgasm in nulliparous healthy women.

    Exclusive breastfeeding for 6 months and continuing it for 2 years, along with complementary feeding, are the primary objectives of public health plans and nutrition around the world. Self-efficacy is a theoretical framework that could be a strong predictive for breastfeeding. This study aimed to determine the effect of message-framing on self-efficacy of breastfeeding in nulliparous women in Shushtar. This quasi-experimental study was conducted in 2015 on 210 nulliparous women in Shushtar (Iran). The participants were randomly allocated into intervention and control groups. The study tool was the short form of breastfeeding self-efficacy scale that was completed on arrival of the study (days 3-5), at the end of week four and at the end of week eight. Data were analyzed by SPSS 19, using Chi-square, ANOVA, and repeated measurements. Mean age of participants was 24.52 years old with standard deviation of 95.4. Mean score of breastfeeding self-efficacy in gain-framed group at days 3-5, week four and week eight was 47.94, 57.43 and 52.8 respectively; in loss-framed group it was 47.76, 56.11 and 52.64 respectively; and in control group it was 45.16, 48.68 and 45.31 respectively. No significant difference was observed between the score of average self-efficacy of days 3-5 and week eight in control group (p=0.93). However, in gain-framed group (p=0.001) and loss-framed group (p=0.004), a significant difference was observed. Results of this study showed that message-framing promotes breastfeeding self-efficacy in nulliparous women and in this regard, there is no difference between gain-framed and loss-framed messages.

    In 1999, WHO proposed a revised classification for myelodysplastic syndromes (MDS). According to this system, FAB low risk MDS (RA and RARS) were defined as such when the presence of dysplastic features was only restricted to the erythroid lineage, and new categories, refractory cytopenia with multilineage dysplasia (RCMD) and refractory cytopenia with multilineage dysplasia and ringed sideroblasts (RCMD-RS), were added. In a retrospective analysis of 240 consecutive patients diagnosed at our institution as having FAB RA and RARS, we reclassified the disease following the WHO criteria and we found that 179/214 patients (84%) still remained in the RA category, while 35/214 (16%) moved to RCMD. Moreover, 17/26 patients (65%) maintained the RARS diagnosis, whereas 9/26 (35%) were re-classified as RCMD-RS. We detected differences among the WHO subgroups as to age and sex distribution as well as to median survival observed by stratifying patients according to different prognostic scoring systems. Furthermore we confirmed the usefulness of WHO segregation with regard to its predictive value for evolution into acute leukaemia. Our study provides evidence that WHO classification may have prognostic impact on MDS subgroups which are usually categorized by FAB as having a favourable outcome.

    The objectives of the present study were to assess the prevalence of cytological endometritis (CYTO) at the time of artificial insemination (AI) and its effect on pregnancy outcomes in nulliparous dairy heifers. In total, 512 endometrial cytology samples were taken during AI from 351 nulliparous Holstein-Friesian heifers using cytotape (a 1.5-cm piece of paper tape rolled on the top of an AI catheter covered with a double guard sheet). After sampling, the top of the AI catheter was gently rolled onto a glass slide, air-dried, and stained using Diff-Quick (Fisher Diagnostics, Newark, DE). For each slide, 300 nucleated cells were counted, and the polymorphonuclear cell ratio (% PMN) was assessed at 400× magnification. We constructed a receiver operating characteristic curve to find the cutoff point at which sensitivity and specificity (% PMN) affected pregnancy outcomes. The receiver operating characteristic curve revealed that the threshold level for diagnosing CYTO in nulliparous dairy heifers was 1% PMN. An insemination was considered successful when pregnancy was confirmed by rectal palpation at least 45d post-AI. Heifers were considered not pregnant when they received a subsequent insemination or were diagnosed empty by rectal palpation. We built multilevel generalized mixed-effect models to test factors affecting pregnancy outcomes and the occurrence of CYTO at AI. We excluded 16 samples harvested from 12 heifers due to poor sample quality or unavailability of reproductive data. Of the 496 AI samples, the prevalence of CYTO at AI was 7.86% (n=39). The conception rate was 62.8% (n=287) in CYTO-negative samples (n=457) and 38.46% (n=15) in CYTO-positive samples. Risk factors for non-pregnancy were a previous AI (odds ratio 2.96; 95% confidence interval: 1.21-7.26) and the interaction between CYTO and previous AI. The only risk factor identified as being associated with the occurrence of CYTO was a previous AI (odds ratio 4.7; 95% confidence interval: 2

    Fear of childbirth is common in women who are pregnant with their first child and is associated with important consequences such as abortions and miscarriages. Twenty percent of nulliparous women seem to exhibit a mild or moderate fear, while 6% present an excessive and irrational fear known as tocophobia. Tocophobia is suggested to be associated with many negative consequences such as postpartum depression (PPD) and Post-traumatic stress (PTS). However, there is little empirical evidence to support these relationships. Recently, Fairbrother and Woody (2007) did not observe a link between the fear of childbirth and symptoms of PPD and PTS in nulliparous women. Some results, near the significance level, could be explained by a lack of statistical power. The present study focused on the link between the fear of childbirth and the process of delivery, the perception of pain, PPD and PTS. More specifically, it aimed to test three hypotheses: (i) fear of childbirth will be linked to the process of delivery, especially regarding the perception of pain, the use of anaesthesia and the use of Caesarean section; (ii) a high level of fear of childbirth will be associated with more negative postpartum consequences (namely PPD/PTS symptoms); (iii) the process of delivery and pain will also be related to post-delivery symptoms. Mediation effects were tested. Data from a longitudinal study were used to meet the hypotheses. A total of 176 nulliparous pregnant women responded to questionnaires at two time measurements (during pregnancy and at 5weeks postpartum). Fear of childbirth is related to the perception of pain at birth among women delivering vaginally, in the absence of anaesthesia. It is also linked to symptoms of PPD and PTS, regardless of whether or not anaesthesia was used. Fear of childbirth also appears to be strongly associated to symptoms of PTS in women who have experienced an unplanned caesarean section. Thus, symptoms of postpartum PTS could play a mediating role

    This study investigated conception rates and other reproductive outcomes achieved with artificial insemination (AI) of nulliparous Holstein heifers using sexed and conventional semen in a commercial Australian dairy herd in central western New South Wales from January 2004 to April 2009. Retrospective data from on-farm records of 9,870 inseminations of 4,456 heifers were analyzed using several mixed models to assess the effect of temperature and humidity surrounding breeding, insemination sire, artificial insemination technician, service number, and heifer weight and age at breeding on reproductive traits (conception rates, sex ratios, gestation length, and abortion and stillbirth rates). Semen was used from 15 sexed sires and 41 unsexed sires. Sexed semen was primarily used at first and second service. Empirical conception rates of 31.6 and 39.6% were achieved for sexed and unsexed semen respectively, whereas model-based predictions were lower, at 21.3 and 32.1%. Conception rates were significantly affected by insemination sire, sex-sorting, heifer age at breeding, temperature and humidity surrounding breeding, service number, and AI technician. Sexed semen yielded 86% heifers, compared with 48% for conventional semen. Significant predictors of calf sex included semen sexing, gestation length, and insemination sire. Twinning rate was high, at 3.6% for both semen types, and gestation length and heifer weight at breeding were significant predictors of twinning. Abortion rates for sexed and unsexed conceptions were similar at 6.1 and 6.5%, respectively, and were affected by heifer age at breeding. Stillbirth rate was affected by calf sex, twinning, gestation length, and AI technician; semen sorting, age at breeding, and temperature and humidity were marginally significant predictors. No abnormalities were observed in the development of offspring, except for a marginally higher stillbirth rate for sexed calves, a finding that needs further investigation. Many

    A low-risk procedure is described for the precise quantitation of changes of trabecular and cortical bone density at peripheral measuring sites. The method is based on quantitative computed tomography (QCT). Bone parameters are calculated for a sample volume common to all examinations of a patient. This is achieved by matching stacks of tomograms according to the cross sectional area of the bone measured. With the help of a special-purpose CT system the described procedure enables a reproducibility for trabecular and cortical bone parameters of 0.3% (1 SD) at a local radiation dose of of 0.1 mSv (10 mrem). The method was used to assess the individual changes in bone density of 39 perimenopausal women during an observation period of 2 to 3 years. The results are grouped according to their menstrual state. Regularly menstruating women experience minute or no changes in bone density. After menopause the interindividual differences are considerable: some women lose bone excessively, others remain relatively stable. The frequency distribution of the rate of bone loss appears to be bimodal. Hence women can be classified in fast losers and slow losers. We conclude that the rate of bone loss may be most helpful in the identification of those women predisposed to osteoporosis. (author)

    Full Text Available Introduction:Most women have experienced child birth and its pain, which is inevitable. If this pain is not controlled it leads to prolonged labor and injury to the mother and fetus. This study was conducted to identify the effect of acupressure on sanyinjiao and hugo points on delivery pain in nulliparous women. Methods:This was a randomized controlled clinical trial on 84 nulliparous women in hospitals of Ardebil, Iran. The participants were divided by randomized blocks of 4 and 6 into two groups. The intervention was in the form of applying pressure at sanyinjiao and hugo points based on different dilatations. The intensity of the pain before and after the intervention was recorded by visual scale of pain assessment. To determine the effect of pressure on the intensity of labor pain, analytical descriptive test was conducted in SPSS (version 13. Results:There was a significant decrease in mean intensity of pain after each intervention in the experimental group with different dilatations (4, 6, 8, and 10 cm. Moreover, the Student’s independent t-test results indicated that the mean intensity of pain in the experimental group after the intervention in all four dilatations was significantly lower than the control group. Repeated measures ANOVA test indicated that in both experimental and control groups in four time periods, there was a statistically significant difference. Conclusion:Acupressure on sanyinjiao and hugo points decreases the labor pain. Therefore, this method can be used effectively in the labor process.

    several studies have been investigated co-activation can enhance the effectveness of PFM training protocols allowing preventive and therapeutic goals in pelvic floor dysfunctions. The objective of the present study was to investigate if an abdominal-pelvic protocol of training (APT) using gametherapy would allow co-activation of PFM and transversus abdominis/oblique internal (TrA/OI) muscles. Twenty-five nulliparous, continent, young females, with median age 24.76 (±3.76) years were evaluated using digital palpation (DP) of PFM and surfasse electromyography of PFM and TrA/OI simultaneously, during maximal voluntary contraction (MVC), alternating PFM and TrA/OI contraction requests. All women participated on a supervised program of APT using gametherapy, that included exercises of pelvic mobilization associated to contraction of TrA/OI muscles oriented by virtual games, for 30 minutes, three times a week, in a total of 10 sessions. Electromyographic data were processed and analyzed by ANOVA - analysis of variance. When MVC of TrA/OI was solicited, it was observed simultaneous increase of electromyographic activity of PFM (p=0.001) following ATP. However, EMG activity did not change significantly during MVC of PFM. Training using gametherapy allowed better co-activation of pelvic floor muscles in response to contraction of TrA, in young nulliparous and continent women.

    Low-risk breast cancer susceptibility alleles or SNPs confer only modest breast cancer risks ranging from just over 1.0 to1.3 fold. Yet, they are common among most populations and therefore are involved in the development of essentially all breast cancers. The mechanism by which the low-risk SNPs confer breast cancer risks is currently unclear. The breast cancer association consortium BCAC has hypothesized that the low-risk SNPs modulate expression levels of nearby located genes. Genotypes of five low-risk SNPs were determined for 40 human breast cancer cell lines, by direct sequencing of PCR-amplified genomic templates. We have analyzed expression of the four genes that are located nearby the low-risk SNPs, by using real-time RT-PCR and Human Exon microarrays. The SNP genotypes and additional phenotypic data on the breast cancer cell lines are presented. We did not detect any effect of the SNP genotypes on expression levels of the nearby-located genes MAP3K1, FGFR2, TNRC9 and LSP1. The SNP genotypes provide a base line for functional studies in a well-characterized cohort of 40 human breast cancer cell lines. Our expression analyses suggest that a putative disease mechanism through gene expression modulation is not operative in breast cancer cell lines

    The Australasian Maternity Outcomes Surveillance System (AMOSS) conducts surveillance and research of rare and serious conditions in pregnancy. This multi-centre population health study is considered low risk with minimal ethical impact. To describe the ethics/governance review pathway undertaken by AMOSS. Prospective, descriptive study during 2009-2011 of the governance/ethical review processes required to gain approval for Australian and New Zealand (ANZ) maternity units with more than 50 births per year (n = 303) to participate in AMOSS. Review processes ranged from a single application for 24 NZ sites, a single application for eligible hospitals in two Australian states, full Health Research Ethics Committee (HREC) applications for individual hospitals, through simple letters of support. As of September 2011, 46 full/expedited ethics applications, 131 site governance applications and 136 letters of support requests were made over 33 months, involving an estimated 3261 hours by AMOSS staff/investigators, and an associated resource burden by participating sites, to obtain approval to receive nonidentifiable data from 291 hospitals. The AMOSS research system provides an important resource to enhance knowledge of conditions that cause rare and serious maternal morbidity. Yet the highly variable ethical approval processes required to implement this study have been excessively repetitive and burdensome. This process jeopardises timely, efficient research project implementation, without corresponding benefits to research participants. The resource burden to establish research governance for AMOSS confirms the urgent need for the Harmonisation of Multi-centre Ethical Review (HoMER) to further streamline ethics/governance review processes for multi-centre research. © 2011 The Authors.

    This study aimed to evaluate the difference of mass in dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) characteristics between low-risk and non-low-risk breast cancers and to explore the possible pathological basis. Approval from the institutional review board and informed consent were acquired for this study. The MR images of 104 patients with pathologically proven breast cancer (104 lesions) were prospectively analyzed. All of included patients were Chinese woman. The DCE-MRI morphologic findings, apparent diffusion coefficient (ADC) values, quantitative DCE-MRI parameters, and pathological biomarkers between the two subtypes of breast cancer were compared. The quantitative DCE-MRI parameters and ADC values were added to the morphologic features in multivariate models to evaluate diagnostic performance in predicting low-risk breast cancer. The values were further subjected to the receiver operating characteristic (ROC) curve analysis. Low-risk tumors showed significantly lower K trans and K e p value s ( t = 2.065, P = 0.043 and t = 3.548, P = 0.001, respectively) and higher ADC value ( t = 4.713, P = 0.000) than non-low-risk breast cancers. Our results revealed no significant differences in clinic data and conventional imaging findings between the two breast cancer subtypes. Adding the quantitative DCE-MRI parameters and ADC values to conventional MRI improved the diagnostic performance of MRI: The area under the ROC improved from 0.63 to 0.91. Low-risk breast cancers showed significantly lower matrix metalloproteinase (MMP)-2 expression ( P = 0.000), lower MMP-9 expression ( P = 0.001), and lower microvessel density (MVD) values ( P = 0.008) compared with non-low-risk breast cancers. K trans and K e p values were positively correlated with pathological biomarkers. The ADC value showed a significant inverse correlation with pathological biomarkers.

    Ellis, Katrina M; Brase, Gary L

    2015-01-01

    Revised Centers for Disease Control and Prevention recommendations on HIV testing now promote testing of most risk groups. However, positive results for low-risk individuals are more likely to be false positives than for high-risk individuals, making clear communication of test results even more imperative. In a study, we evaluated current counseling of low-risk test recipients via a sample of 29 HIV hotline counselors from U.S. state and national hotlines. 100% of counselors interviewed failed to provide an accurate conditional HIV risk for low-risk women, but were more likely than a 1998 German sample to report that false positives could occur. In a second study, undergraduates read idealized transcripts of interviews with HIV counselors and computed conditional risk for a low-risk individual. The natural frequency format offered a small but significant improvement in conditional reasoning, comparable to the effect of numerical literacy. Applications for ecologically valid numerical presentations of risk and implications for numeracy are discussed.

  18. Second trimester hepatic rupture in a 35 year old nulliparous woman with HELLP syndrome: a case report.

    LENUS (Irish Health Repository)

    Kelly, J

    2009-01-01

    The HELLP syndrome (haemolysis, elevated liver blood tests and low platelets) is a serious complication in pregnancy characterized by haemolysis, elevated liver enzymes and low platelet count occurring in 0.5 to 0.9% of all pregnancies and in 10-20% of cases with severe preeclampsia. Hepatic capsular rupture is a rare yet dramatic complication of HELLP syndrome. The majority of cases occur in multiparous women over the age of 30. Classically it presents with acute onset right upper quadrant pain in the presence of constitutional symptoms such as vomiting and pyrexia. However, symptoms and signs are usually non specific. Spontaneous hepatic rupture can be preceded by signs of hypovolaemic shock; yet the diagnosis is infrequently made prior to emergent laparotomy. We present the case of a 35 year old nulliparous woman with a second trimester gestational hepatic rupture associated with HELLP syndrome. We briefly discuss the aetiology, diagnostic difficulties and treatment options associated with this rare presentation.

    We examined pelvic floor muscles (PFM) activity (%MVC) in twenty nulliparous women by body position during exercise as well as the activation of abdominal muscles and the gluteus maximus during voluntary contractions of the PFMs. Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Activation of transversus abdominis, rectus abdominis, and gluteus maximus during voluntary PFM contractions was also assessed. Significant differences in mean normalized amplitudes of baseline PFM activity were revealed between standing and lying (P activity seemed to depend on the body position and was the highest in standing. Pelvic floor muscles activity during voluntary contractions did not differ by position in continent women. Statistically significant differences between the supine lying and sitting positions were only observed during a sustained 60-second contraction of the PFMs.

    2017-01-01

    Full Text Available Background & Aim: Episiotomy is one of the most common surgical procedures in obstetrics, which requires analgesia. Entonox gas is known to have analgesic and sedative properties. However, no studies have been found on the analgesic effects of Entonox on episiotomy incision. Therefore, this study aimed to compare the effects of Entonox and lidocaine on pain intensity during episiotomy incision in nulliparous women. Materials and Methods: This randomized controlled trial was conducted on 120 term nulliparous women, who met the inclusion criteria. Subjects were selected by randomized sampling and equally divided into two groups of intervention and control (n=60. In the intervention group, Entonox gas was applied two minutes before episiotomy incision until the end of the procedure. On the other hand, the control group received 5 ml of lidocaine 2% as routine care before episiotomy incision. Data were collected using visual analogue scale to compare the study groups in terms of pain intensity. In addition, patient satisfaction with pain management technique during episiotomy and side effects of Entonox were assessed. Data analysis was performed in SPSS version 22 using Mann-Whitney U and Chi-square tests, and P value of less than 0.05 was considered statistically significant. Results: In this study, no significant difference was observed between the intervention and control groups regarding pain intensity (P=0.52. Moreover, no significant difference was observed in the satisfaction level of the two groups (P=0.70. Conclusion: According to the results of this study, Entonox could be used as an effective and noninvasive alternative to lidocaine to reduce pain during episiotomy incision without significant side effects.

    To analyse anatomical characteristics of the pelvic floor in young nulliparous volunteers based on three-dimensional MRI. Thin-slice MRI was performed in 25 young nulliparous volunteers in Southern Medical University, MRI were imported into Mimics 10.01 for 3D reconstruction.Using 3D models we measured follow indicators: the levator ani muscle volume (LVOL) , levator plate angle (LPA), levator hiatus width (LH-W)and length (LH-L), distance between symphysis and levator sling muscle (LSG). (1) 25 cases of pelvic three-dimensional models was successfully constructed, including the pelvis, pelvic organs and the pelvic floor muscles (including the ischial coccyx muscle, levator ani muscle and its various components, perineal muscles), the models could be able to clearly reflect the level of the pelvic floor muscles; (2) 25 cases of levator ani muscle measurement results:LVOL: (34 ± 6) cm(3), LPA: (43 ± 4) °, LH-W: (33 ± 4) mm, LH-L: (54 ± 5) mm, left LSG: (18.8 ± 2.5) mm, right LSG: (18.3 ± 2.5) mm. It is an effective way to use the computer to reconstruct the 3D model of female pelvic floor muscles using MRI data set. The quantitative analysis of levator ani muscle three-dimensional model can be assessed pelvic floor function, which is of great value in clinical practice.It is helpful to understand the pelvic floor disorders pathogenesis, clinical diagnosis, treatment options and treatment evaluation to provide reference standards.

    Data on serial cervical length (CL) measurements in pregnancy at term to predict spontaneous labour onset are scarce and conflicting. This study was conducted to observe CL changes preceding spontaneous onset of labour, by serial transvaginal sonography (TVS) and transabdominal sonography (TAS), in nulliparous Indian women near term. Only nulliparous women with a singleton foetus in cephalic presentation and who confirmed their gestational age were recruited. Sonographic CL measurements were taken at weekly intervals from 36 wk gestation onwards by a single ultrasonologist. Transabdominal and transvaginal measurements were undertaken using the suitable transducer probes with the women in the supine position. A total of 104 women with spontaneous onset of labour were evaluated. There was substantial variation in CL measurements, both by TVS and by TAS, from 36 to 40 wk gestation, although the two sets of measurements correlated closely. Mean CL changed significantly over the last three weeks before delivery. However, only one-third of the women showed CL change of >5 mm per week in the last three weeks. There was poor correlation between gestational age at delivery and the last measured CL, either by TVS or TAS. Length >3.1 mm, measured by TVS at 38 wk gestation, predicted post-dated pregnancy to a limited extent. Inter-individual variations in CL and in CL changes were large. Thus, it was not practical to predict spontaneous onset of labour by sonographic CL measurement near term. Post-dated pregnancy may be predicted with limited success. Further studies should explore other parameters, in addition to CL.

    Reducing labor pain and anxiety is one of the most important goals of maternity care. This study aimed to assess the effects of aromatherapy with Rosa damascena on pain and anxiety in the first stage of labor among nulliparous women. This was a randomized clinical trial of 110 nulliparous women. The eligible participants were randomly assigned to two groups of aromatherapy and control in an Iranian maternity hospital. The participants received 0.08 mL of Rosa damascena essence in the aromatherapy group and 0.08 mL of normal saline in the control group, every 30 min. Pain was measured 3 times, once each at three stages of cervical dilation (4-5, 6-7, and 8-10 cm). Anxiety was measured twice, once each at two stages of cervical dilation (4-7 and 8-10 cm). The tools for data collection were the Spielberger anxiety questionnaire, numerical pain rating scale, demographic and obstetric questionnaire, and an observational checklist. Data analyses included the t-test, Mann-Whitney U test and Chi-square test. Severity of labor pain and severity of anxiety were used as primary outcome measures. Labor and delivery characteristics (including number of contractions, duration of contractions in second stage, Bishop score, augmentation by oxytocin, Apgar score, and mode of delivery), demographic characteristics, and fertility information were used as secondary outcome measures. Pain severity in the group receiving aromatherapy with R. damascena was significantly lower than in the control group after treatment at each pain assessment (cervical dilation of 4-5, 6-7, and 8-10 cm; P labor. Aromatherapy with R. damascena is a convenient and effective method for pain and anxiety reduction during the first stage of labor. Iranian Registry of Clinical Trial: IRCT201306258801N3.

    Determine predictors of high-risk and low-risk oral HPV infection in the United States. Retrospective analyses of National Health and Nutrition Examination Survey cross-sectional data of U.S. population from 2009 to 2012. Database queried for subjects aged 18 to 69 with oral rinse human papillomavirus (HPV) DNA data. Logistic regression identified factors associated with high-risk and low-risk infection. Covariates included age, gender, ethnicity, income-to-poverty (IP) ratio, sexual orientation, human immunodeficiency virus infection, other sexually transmitted infections, lifetime sexual partners, and lifetime oral sex partners. In total, 9,256 subjects were identified with mean age of 42.1 years. Oral HPV infection was present in 8.1% (N = 747); 55.7% were high-risk and 55.3% were low-risk types, including 11% with both. Oral infection had a negative association with female gender (odds ratio [OR] 0.3, P oral sex partner (OR 0.7, P = 0.03). Increasing oral sex behavior (6-21+ lifetime partners) was positively associated with oral HPV (OR 1.4-3.0, P = 0.03). Low-risk infection had negative associations with female gender (OR 0.4, P 20 sexual partners (all sex OR 1.7, P = 0.04; oral sex OR 1.9, P = 0.02). Predictors of high-risk HPV infection included male gender and increasing oral sex partners. Increasing oral sex partners is positively associated with oral HPV infection; female sex and higher socioeconomic class are negatively associated. The risk-factor profiles for high-risk and low-risk HPV types are distinct, with similar trends related to sexual behaviors. 4.

    Androgen deprivation therapy (ADT) is not recommended for low-risk prostate cancer because of its lack of benefit and potential for harm. We evaluated the incidence and predictors of ADT use in low-risk disease. Using the National Cancer Database, we identified 197,957 patients with low-risk prostate cancer (Gleason score of 3 + 3 = 6, prostate-specific antigen level used multiple logistic regression to evaluate predictors of ADT use and Cox regression to examine its association with all-cause mortality. Overall ADT use decreased from 17.6% in 2004 to 3.5% in 2012. In 2012, 11.5% of low-risk brachytherapy patients and 7.6% of external beam radiation therapy patients received ADT. Among 82,352 irradiation-managed patients, predictors of ADT use included treatment in a community versus academic cancer program (adjusted odds ratio [AOR], 1.60; 95% confidence interval [CI], 1.50-1.71; Puse versus external beam radiation therapy (AOR, 1.32; 95% CI, 1.27-1.37; Puse included a Charlson-Deyo comorbidity score of ≥2 versus 0 (AOR, 1.42; 95% CI, 1.06-1.91; P=.018); treatment in a community versus academic cancer program (AOR, 1.61; 95% CI, 1.37-1.90; Puse was associated with increased all-cause mortality in patients who did not receive local therapy (adjusted hazard ratio, 1.28; 95% CI, 1.14-1.43; Puse in low-risk prostate cancer has declined nationally but may remain an issue of concern in certain populations and regions.

    Introduction  Pentasomy 49,XXXXY is a sex chromosome anomaly difficult to be diagnosed prenatally. We describe a patient of pentasomy 49,XXXXY with false low-risk results using a noninvasive prenatal screening (NIPS). A 30-year-old G1P0 woman presented at 33 6/7 weeks, secondary to sonographic fetal anomalies. She had low-risk NIPS at 13 6/7 weeks. Anatomy survey showed bilateral clubfeet, clinodactyly of the left fifth digit, micropenis, and echogenic bowel. Cytogenetics analysis revealed pentasomy 49,XXXXY syndrome. We report third-trimester sonographic features of a fetus with pentasomy 49,XXXXY and the importance of thorough pre- and posttest counseling for NIPS.

  10. Induction of labor and risk of postpartum hemorrhage in low risk parturients.

    Directory of Open Access Journals (Sweden)

    Imane Khireddine

    Full Text Available OBJECTIVE: Labor induction is an increasingly common procedure, even among women at low risk, although evidence to assess its risks remains sparse. Our objective was to assess the association between induction of labor and postpartum hemorrhage (PPH in low-risk parturients, globally and according to its indications and methods. METHOD: Population-based case-control study of low-risk women who gave birth in 106 French maternity units between December 2004 and November 2006, including 4450 women with PPH, 1125 of them severe, and 1744 controls. Indications for labor induction were standard or non-standard, according to national guidelines. Induction methods were oxytocin or prostaglandins. Multilevel multivariable logistic regression modelling was used to test the independent association between induction and PPH, quantified as odds ratios. RESULTS: After adjustment for all potential confounders, labor induction was associated with a significantly higher risk of PPH (adjusted odds ratio, AOR1.22, 95%CI 1.04-1.42. This excess risk was found for induction with both oxytocin (AOR 1.52, 95%CI 1.19-1.93 for all and 1.57, 95%CI 1.11-2.20 for severe PPH and prostaglandins (AOR 1.21, 95%CI 0.97-1.51 for all and 1.42, 95%CI 1.04-1.94 for severe PPH. Standard indicated induction was significantly associated with PPH (AOR1.28, 95%CI 1.06-1.55 while no significant association was found for non-standard indicated inductions. CONCLUSION: Even in low risk women, induction of labor, regardless of the method used, is associated with a higher risk of PPH than spontaneous labor. However, there was no excess risk of PPH in women who underwent induction of labor for non-standard indications. This raises the hypothesis that the higher risk of PPH associated with labor induction may be limited to unfavorable obstetrical situations.

    2012-01-01

    This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear.

    To derive low-risk gambling limits using the method developed by Currie et al. (2006) applied to longitudinal data. Secondary analysis of data from the Quinte Longitudinal Study (n = 3054) and Leisure, Lifestyle and Lifecycle Project (n = 809), two independently conducted cohort studies of the natural progression of gambling in Canadian adults. Community-dwelling adults in Southeastern Ontario and Alberta, Canada. A total of 3863 adults (50% male; median age = 44) who reported gambling in the past year. Gambling behaviours (typical monthly frequency, total expenditure and percentage of income spent on gambling) and harm (experiencing two or more consequences of gambling in the past 12 months) were assessed with the Canadian Problem Gambling Index. The dose-response relationship was comparable in both studies for frequency of gambling (days per month), total expenditure and percentage of household income spent on gambling (area under the curve values ranged from 0.66 to 0.74). Based on the optimal sensitivity and specificity values, the low-risk gambling cut-offs were eight times per month, $75CAN total per month and 1.7% of income spent on gambling. Gamblers who exceeded any of these limits at time 1 were approximately four times more likely to report harm at time 2 [95% confidence interval (CI) = 2.9-6.6]. Longitudinal data in Canada suggest low-risk gambling thresholds of eight times per month, $75CAN total per month and 1.7% of income spent on gambling, all of which are higher than previously derived limits from cross-sectional data. Gamblers who exceed any of the three low-risk limits are four times more likely to experience future harm than those who do not. © 2017 Society for the Study of Addiction.

    To examine the clinical utility and cost of follow-up ultrasounds performed as a result of suboptimal views at the time of initial second-trimester ultrasound in a cohort of low-risk pregnant women. We conducted a retrospective cohort study of women at low risk for fetal structural anomalies who had second-trimester ultrasounds at 16 to less than 24 weeks of gestation from 2011 to 2013. We determined the probability of women having follow-up ultrasounds as a result of suboptimal views at the time of the initial second-trimester ultrasound, and calculated the probability of detecting an anomaly on follow-up ultrasound. These probabilities were used to estimate the national cost of our current ultrasound practice, and the cost to identify one fetal anomaly on follow-up ultrasound. During the study period, 1,752 women met inclusion criteria. Four fetuses (0.23% [95% CI 0.06-0.58]) were found to have anomalies at the initial ultrasound. Because of suboptimal views, 205 women (11.7%) returned for a follow-up ultrasound, and one (0.49% [95% CI 0.01-2.7]) anomaly was detected. Two women (0.11%) still had suboptimal views and returned for an additional follow-up ultrasound, with no anomalies detected. When the incidence of incomplete ultrasounds was applied to a similar low-risk national cohort, the annual cost of these follow-up scans was estimated at $85,457,160. In our cohort, the cost to detect an anomaly on follow-up ultrasound was approximately $55,000. The clinical yield of performing follow-up ultrasounds because of suboptimal views on low-risk second-trimester ultrasounds is low. Since so few fetal abnormalities were identified on follow-up scans, this added cost and patient burden may not be warranted. © 2016 Wiley Periodicals, Inc.

    A set of low-risk gambling limits were recently produced using Canadian epidemiological data on the intensity of gambling behavior and related consequences (Currie et al. Addiction 101:570-580, 2006). The empirically derived limits (gambling no more than two to three times per month, spending no more than $501-$100o CAN per year or no more than 1% of gross income spent on gambling) accurately predicted risk of gambling-related harm after controlling for other risk factors. The present study sought to replicate these limits on data collected in three independently conducted Canadian provincial gambling surveys. Dose-response curves and logistic regression analyses were applied to gambling prevalence data collected in surveys conducted in 2001-2002 within the provinces of Alberta, British Columbia, and Ontario (combined sample N = 7,675). A comparable dose-response relationship between gambling intensity and risk of harm was found in each province. The optimal thresholds for defining an upper limit of low-risk gambling were similar across the three provinces despite variations in the availability and organization of legalized gambling opportunities within each region. These results provide additional evidence supporting the validity of the low-risk gambling limits. Quantitative limits could be used to augment existing responsible gambling guidelines.

    As recommended by current NCCN guidelines, patients with very low-risk prostate cancer may be treated with active surveillance (AS), but this may be underutilized. Using the National Cancer Database (NCDB), we identified men (2010-2013) with biopsy-proven, very low-risk prostate cancer that met AS criteria as suggested by Epstein (stage ≤ T1c; Gleason score (GS) ≤ 6; PSA  1 compared to younger groups), uninsured (vs. any insurance type, OR's > 1); or treated at academic/research center (OR > 1). The overall use of AS increased from 11.6% (2010) to 27.3% (2013). We found a low, but rising rate of AS in a nationally representative group of very low-risk prostate cancer patients. Disparities in the use of AS may be targeted to improve adherence to national guidelines. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Full Text Available Aim. To evaluate efficacy and toxicity of image-guided hypofractionated radiotherapy (HFRT in the treatment of low-risk prostate cancer. Outcomes and toxicities of this series of patients were compared to another group of 32 low-risk patients treated with conventional fractionation (CFRT. Methods. Fifty-nine patients with low-risk prostate cancer were analysed. Total dose for the prostate and proximal seminal vesicles was 60 Gy delivered in 20 fractions. Results. The median follow-up was 30 months. The actuarial 4-year overall survival, biochemical free survival, and disease specific survival were 100%, 97.4%, and 97.4%, respectively. Acute grade 1-2 gastrointestinal (GI and genitourinary (GU toxicity rates were 11.9% and 40.7%, respectively. Grade 1 GI and GU late toxicity rates were 8.5% and 13.6%, respectively. No grade ≥2 late toxicities were recorded. Acute grade 2-3 GU toxicity resulted significantly lower (P=0.04 in HFRT group compared to the CFRT group. The cumulative 4-year incidence of grade 1-2 GU toxicity was significantly higher (P<0.001 for HFRT patients. Conclusions. Our study demonstrated that hypofractionated regimen provided excellent biochemical control in favorable risk prostate cancer patients. The incidence of GI and GU toxicity was low. However, HFRT presented higher cumulative incidence of low-grade late GU toxicity than CFRT.

    Active surveillance is an important option to reduce prostate cancer overtreatment, but it remains underutilized in many countries. Models from the United States show that greater use of active surveillance is important for prostate cancer screening to be cost-effective. To perform an up-to-date, nationwide, population-based study on use of active surveillance for localized prostate cancer in Sweden. Cross-sectional study in the National Prostate Cancer Register (NPCR) of Sweden from 2009 through 2014. The NPCR has data on 98% of prostate cancers diagnosed in Sweden and has comprehensive linkages to other nationwide databases. Overall, 32 518 men with a median age of 67 years were diagnosed with favorable-risk prostate cancer, including 4693, 15 403, and 17 115 men with very-low-risk (subset of the low-risk group) (clinical stage, T1c; Gleason score, ≤6; prostate-specific antigen [PSA], Sweden, with the highest rates yet reported and almost complete uptake for very-low-risk cancer. These data should serve as a benchmark to compare the use of active surveillance for favorable-risk disease around the world.

    Most patients with newly diagnosed differentiated thyroid carcinoma have tumors with low risk of mortality and recurrence. Standard therapy has been total or near total thyroidectomy followed by postoperative radioiodine remnant ablation (RRA). Although RRA provides benefits, current clinical guidelines do not recommend it universally, since an increase in disease-free survival or a decrease in mortality in low risk patients has not been demonstrated so far. Advancements in our understanding of the biological behavior of thyroid cancer have been translated into the clinic in a personalized approach to the patients based on their individual risk of recurrence and mortality. Current evidence suggests that RRA is not indicated in most low-risk patients, especially those with papillary carcinomas smaller than 1cm, without extrathyroidal extension, unfavorable histology, lymph node involvement or distant metastases. Follow-up of these patients with serial measurements of serum thyroglobulin and neck ultrasound is adequate. Careful evaluation of all risk factors of clinical relevance will allow a more realistic assessment of each individual patient. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    Strenuous physical activity, which is known to increase intraabdominal pressure and theoretically places stress on the pelvic floor, may affect pelvic support in nulliparous women. The aims of this study were to: (1) examine the differences in maximal vaginal descent (MVD), vaginal resting pressure (VRP), and pelvic floor muscle strength (PFMS) between women who habitually perform strenuous exercise vs women who refrain from performing strenuous exercise; and (2) compare MVD, VRP, and PFMS before and immediately following physical activity in the strenuous and nonstrenuous groups separately. Participants were healthy nulliparous women ages 18-35 years who were habitual strenuous or nonstrenuous exercisers. Women in the strenuous group participated in CrossFit (CrossFit, Inc., Washington, DC) at least 3 days per week for at least 6 months. We assessed anthropometric and body composition values using standardized procedures. Participants completed the Pelvic Organ Prolapse Quantification examination and pelvic muscle strength assessment before and again within 15 minutes of completing exercise (CrossFit for the strenuous group and self-paced walking for the nonstrenuous). A research nurse masked to study group assignment recorded MVD, defined as the greatest value of anterior, posterior, or apical support, and VRP and PFMS using a perineometer. Maximal PFMS was recorded as the highest pressure measured in 3 vaginal contraction trials. Data were analyzed using parametric and nonparametric tests as appropriate. P < .05 was considered significant. Seventy nulliparous women participated in the study, 35 in each group. The mean age was 24.77 ± 4.3 years. Compared to the nonstrenuous group, strenuous participants were heavier (64.70 ± 7.78 kg vs 60.6 ± 8.99 kg, P = .027), had lower percent body fat (23.36 ± 5.88% vs 27.55 ± 7.07%, P = .003), and had higher handgrip strength (20.78 ± 5.97 kg vs 16.04 ± 11.04 kg, P = .001).

    Purpose: Androgen deprivation therapy (ADT) is not recommended for low-risk prostate cancer because of its lack of benefit and potential for harm. We evaluated the incidence and predictors of ADT use in low-risk disease. Methods and Materials: Using the National Cancer Database, we identified 197,957 patients with low-risk prostate cancer (Gleason score of 3 + 3 = 6, prostate-specific antigen level <10 ng/mL, and cT1-T2a) diagnosed from 2004 to 2012 with complete demographic and treatment information. We used multiple logistic regression to evaluate predictors of ADT use and Cox regression to examine its association with all-cause mortality. Results: Overall ADT use decreased from 17.6% in 2004 to 3.5% in 2012. In 2012, 11.5% of low-risk brachytherapy patients and 7.6% of external beam radiation therapy patients received ADT. Among 82,352 irradiation-managed patients, predictors of ADT use included treatment in a community versus academic cancer program (adjusted odds ratio [AOR], 1.60; 95% confidence interval [CI], 1.50-1.71; P<.001; incidence, 14.0% vs 6.0% in 2012); treatment in the South (AOR, 1.51), Midwest (AOR, 1.81), or Northeast (AOR, 1.90) versus West (P<.001); and brachytherapy use versus external beam radiation therapy (AOR, 1.32; 95% CI, 1.27-1.37; P<.001). Among 25,196 patients who did not receive local therapy, predictors of primary ADT use included a Charlson-Deyo comorbidity score of ≥2 versus 0 (AOR, 1.42; 95% CI, 1.06-1.91; P=.018); treatment in a community versus academic cancer program (AOR, 1.61; 95% CI, 1.37-1.90; P<.001); and treatment in the South (AOR, 1.26), Midwest (AOR, 1.52), or Northeast (AOR, 1.28) versus West (P≤.008). Primary ADT use was associated with increased all-cause mortality in patients who did not receive local therapy (adjusted hazard ratio, 1.28; 95% CI, 1.14-1.43; P<.001) after adjustment for age and comorbidity. Conclusions: ADT use in low-risk prostate cancer has declined nationally but may remain an issue

Setting Three NHS Trusts. Population Nulliparous women not planning elective caesarean, without medication for hypertension and without psychological illness. Methods Randomisation at 28–32 weeks’ gestation to usual care, or to usual care plus brief self-hypnosis training (two × 90-minute groups at around 32 and 35 weeks’ gestation; daily audio self-hypnosis CD). Follow up at 2 and 6 weeks postnatal. Main outcome measures Primary: epidural analgesia. Secondary: associated clinical and psychological outcomes; cost analysis. Results Six hundred and eighty women were randomised. There was no statistically significant difference in epidural use: 27.9% (intervention), 30.3% (control), odds ratio (OR) 0.89 [95% confidence interval (CI): 0.64–1.24], or in 27 of 29 pre-specified secondary clinical and psychological outcomes. Women in the intervention group had lower actual than anticipated levels of fear and anxiety between baseline and 2 weeks post natal (anxiety: mean difference −0.72, 95% CI −1.16 to −0.28, P = 0.001); fear (mean difference −0.62, 95% CI −1.08 to −0.16, P = 0.009) [Correction added on 7 July 2015, after first online publication: ‘Mean difference’ replaced ‘Odds ratio (OR)’ in the preceding sentence.]. Postnatal response rates were 67% overall at 2 weeks. The additional cost in the intervention arm per woman was £4.83 (CI −£257.93 to £267.59).

    Background: In China, no multicenter double-blinded prospective randomized controlled study on labor induction has been conducted till now. This study is to evaluate the efficacy and safety of intravaginal accurate 25-μg misoprostol tablets for cervical ripening and labor induction in term pregnancy in nulliparous women. Methods: This was a double-blinded, prospective randomized controlled study including nulliparous women from 6 university hospitals across China. Subjects were randomized into misoprostol or placebo group with the sample size ratio set to 7:2. Intravaginal 25-μg misoprostol or placebo was applied at an interval of 4 h (repeated up to 3 times) for labor induction. Primary outcome measures were the incidence of cumulative Bishop score increases ≥3 within 12 h or vaginal delivery within 24 h. Safety assessments included the incidences of maternal morbidity and adverse fetal/neonatal outcomes. Results: A total of 173 women for misoprostol group and 49 women for placebo were analyzed. The incidence of cumulative Bishop score increases ≥3 within 12 h or vaginal delivery within 24 h was higher in the misoprostol group than in the placebo (64.2% vs. 22.5%, relative risk [RR]: 2.9, 95% confidence interval [CI]: 1.4–6.0). The incidence of onset of labor within 24 h was significantly higher in the misoprostol group than in the placebo group (48.0% vs. 18.4%, RR: 2.6, 95% CI: 1.2–5.7); and the induction-onset of labor interval was significantly shorter in the misoprostol group (P = 0.0003). However, there were no significant differences in the median process time of vaginal labor (6.4 vs. 6.8 h; P = 0.695), incidence (39.3% vs. 49.0%, RR: 0.8, 95% CI: 0.4–1.5) and indications (P = 0.683) of cesarean section deliveries, and frequencies of maternal, fetal/neonatal adverse events between the groups. Conclusion: Intravaginal misoprostol 25 μg every 4 h is efficacious and safe in labor induction and cervical ripening. PMID:26481739

    The authors pose the question - What is the best treatment to reduce the need for caesarean section in nulliparous women at term with delayed first stage of labour? and state in their paper that "There is no consensus on the optimal dose regimen of oxytocin for delay in the first stage of labour...... in nulliparous women at term (37-42 weeks’ gestation) to reduce unplanned caesarean section and increase vaginal birth with minimal adverse events". However, they describe only low and high dose oxytocin regimens and fail to acknowledge that no oxytocin at all is associated with a spontaneous delivery just...... implies that these are the only options for addressing an improvement in the mode of delivery in slow labour. Although oxytocin shortens labour, it does so at the expense of an increase in uterine hyperstimulation and abnormal fetal heart rate patterns, and this may not be to the advantage of either...

    Continuity of midwife-led care is recommended in maternity care because of its various positive outcomes. In Japan, midwife-led care is receiving broad attention as well. In order to popularise midwifery care within the entire system of perinatal care in Japan, there is a need to show evidence that continuity of midwife care for women will bring about positive outcomes. The objectives of this study were to compare the health outcomes of women and infants who received midwife-led care with obstetrician-led care in Japan. This was an observational study using non-random purposive sampling with a survey questionnaire. Settings where midwife-led care and obstetrician-led care were chosen by purposive samples. Participants were low-risk women who received antenatal care and delivered a term-singleton-infant at the participating settings during the research period. Measurements were: Women-centred care pregnancy questionnaire, Stein's maternity blues questionnaire, and Edinburgh Postnatal Depression Scale. Midwife-led care was perceived by women to be beneficial and had no adverse outcomes compared to obstetrician-led care. Main findings are: (1) Perception of Women-centred care was higher; (2) Less premature rupture of membranes, and the Apgar scores of the infants were similar; (3) Exclusively breast-feeding during hospitalisation and at one-month postpartum; (4) Stein's maternity blues scale scores was lower in women who received midwife-led care than those who received obstetrician-led care. Continuity of midwife-led care was perceived by women to be beneficial and had no adverse outcomes. Therefore, midwife-led care in low-risk pregnancy could be applicable and recommended.

    Use of intrauterine devices (IUDs) by US women is low despite their suitability for most women of reproductive age and in a variety of clinical contexts. This study examined obstetrician-gynecologists' practices and opinions about the use of IUDs in adolescents, nulliparous women and other patient groups, as well as for emergency contraception. A survey questionnaire was sent to a computer-generated sample of 3000 fellows who were reflective of the American College of Obstetricians and Gynecologists (College) membership. After exclusions from the 1552 returned surveys (51.7% response rate), 1150 eligible questionnaires were analyzed. Almost all obstetrician-gynecologists (95.8%) reported providing IUDs, but only 66.8% considered nulliparous women, and 43.0% considered adolescents appropriate candidates. Even among obstetrician-gynecologists who recalled reading a College publication about IUDs, only 78.0% and 45.0% considered nulliparous women and adolescents appropriate candidates, respectively. Few respondents (16.1%) had recommended the copper IUD as emergency contraception, and only 73.9% agreed that the copper IUD could be used as emergency contraception. A total of 67.3% of respondents agreed that an IUD can be inserted immediately after an abortion or miscarriage. Fewer (43.5%) agreed that an IUD can be inserted immediately postpartum, and very few provide these services (11.4% and 7.2%, respectively). Staying informed about practice recommendations for long-acting reversible contraception was associated with broader provision of IUDs. Although most obstetrician-gynecologists offer IUDs, many exclude appropriate candidates for IUD use, both for emergency contraception and for long-term use, despite evidence-based recommendations. This study shows that obstetrician-gynecologists still do not offer IUDs to appropriate candidates, such as nulliparous women and adolescents, and rarely provide the copper IUD as emergency contraception.

    Full Text Available Introduction: Anxiety increases significantly during labor, especially among nulliparous women. Such anxiety may affect the progress of labor and physiological parameters. The use of essential oils of aromatic plants, or aromatherapy, is a non-invasive procedure that can decrease childbirth anxiety. This study examined the effect of inhalation of the aroma of geranium essential oil on the level of anxiety and physiological parameters of nulliparous women in the first stage of labor. Methods: In study, was carried out on 100 nulliparous women admitted to Bent al-Hoda Hospital in the city of Bojnord in North Khorasan province of Iran during 2012-2013. The women were randomly assigned to two groups of equal size, one experimental group (geranium essential oil and one control (placebo group. Anxiety levels were measured using Spielberger’s questionnaire before and after intervention. Physiological parameters (systolic and diastolic blood pressure, respiratory rate, pulse rate were also measured before and after intervention in both groups. Data analysis was conducted using the x2 test, paired t-test, Mann-Whitney U test, and Wilcox on test on SPSS 11.5. Results: The mean anxiety score decreased significantly after inhalation of the aroma of geranium essential oil. There was also a significant decrease in diastolic blood pressure.Conclusion: Aroma of essential oil of geraniums can effectively reduce anxiety during labor and can be recommended as a non-invasive anti-anxiety aid during childbirth.

    Full Text Available The aim of this study was to determine the content of magnesium, copper, cadmium and iron in umbilical cord blood of the newborns depending on the number of pregnancies. It was established correlations between average concentrations these metals in cord blood and newborn’s parameters. The study material was collected immediately after delivery from the Department of Obstetrics and Gynecology in Bytom. The cord blood was taken from 99 women between 29-40 years old. Women were divided into two groups: nulliparous and multiparous. The concentration of metals in the cord blood was determined by flame atomic absorption spectrometry (FAAS. The conducted study demonstrates that magnesium, copper, cadmium and iron were noted in all tissues, both nulliparous women and multiparous mothers. The maximum concentration of cadmium in umbilical cord blood was observed among multiparous mothers (2.229 mg.kg-1 d.m.. In group of nulliparous women was observed higher concentration of Fe, Mg and Cu in umbilical cord blood than in multiparous mothers. It was noted some statistically significant correlation between iron, copper and newborn’s parameters. Parity influences the concentration of cadmium in umbilical cord blood with higher level found in multiparous women. Average content of iron in cord blood did not decrease with parity, it indicate that this element is preferentially taken up by the child.

    It is to compare the levels of fasting glucose and insulin as well as insulin resistance in grand multiparas with primiparity and nulliparity. Fasting blood samples were collected from 100 non-pregnant ladies as control group, 100 primiparity pregnant women and 100 grand multiparity pregnant women. Glucose (FBS) and insulin (FSI) concentrations were measured by Hitachi 912 full automated Chemistry Analyzer (Roche Diagnostics, Germany) as manufacturer procedure. Insulin resistance was calculated following the formula: FBG (mg dL-1)×FSI (μU mL-1)/405. This study found a significant reduction in glucose level in primiparity when compared to control group but it was increased significantly in multiparity comparing to primiparity and control. Insulin level showed significant high concentrations in pregnant women and increased significantly in grand multiparas comparing to primiparas and controls. As a result of that, HOMA-IR was increased significantly by increasing of parity. Also, there was a significant increase in fasting insulin and a decrease in insulin sensitivity with parity with association to age and obesity. Grand multiparity is associated with an increased risk of subsequent clinical insulin resistance (HOMA-IR).

    Infant expressions are important signals for eliciting caregiving behaviors in parents. The present study sought to test if infant expressions affect adults' behavioral response, taking into account the role of a mood induction and childhood caregiving experiences. A modified version of the Approach Avoidance Task (AAT) was employed to study nulliparous female university students' implicit responses to infant faces with different expressions. Study 1 showed that sad, neutral and sleepy expressions elicit a tendency for avoidance, while no tendency for approach or avoidance was found for happy faces. Notably, differences between approach and avoidance response latencies for sad faces and participants' negative caregiving experiences were positively correlated (r=0.30, p=0.04, Bonferroni corrected), indicating that individuals who experienced insensitive parental care show more bias toward sad infant faces. In Study 2, we manipulated participants' current mood (inducing sad and happy mood by asking to recall a happy or sad event of their recent life) before the AAT. Results showed that sad mood enhanced the bias toward sad faces that is buffered by positive mood induction. In conclusion, these findings indicate that implicit approach avoidance behaviors in females depend on the emotional expression of infant faces and are associated with childhood caregiving experiences and current mood.

    2009-06-01

    Full Text Available Abstract The HELLP syndrome (haemolysis, elevated liver blood tests and low platelets is a serious complication in pregnancy characterized by haemolysis, elevated liver enzymes and low platelet count occurring in 0.5 to 0.9% of all pregnancies and in 10–20% of cases with severe preeclampsia. Hepatic capsular rupture is a rare yet dramatic complication of HELLP syndrome. The majority of cases occur in multiparous women over the age of 30. Classically it presents with acute onset right upper quadrant pain in the presence of constitutional symptoms such as vomiting and pyrexia. However, symptoms and signs are usually non specific. Spontaneous hepatic rupture can be preceded by signs of hypovolaemic shock; yet the diagnosis is infrequently made prior to emergent laparotomy. We present the case of a 35 year old nulliparous woman with a second trimester gestational hepatic rupture associated with HELLP syndrome. We briefly discuss the aetiology, diagnostic difficulties and treatment options associated with this rare presentation.

    Type and volume of fluid administered for intrapartum maintenance had been reported to differently affect labor length, delivery mode, and cord artery pH and glucose level. We aimed to compare the effect of three different fluid regimens on labor duration. In a randomized trial, healthy nulliparous in labor were randomized into one of three intravenous fluid regimens: group 1, the reference group, lactated Ringer's solution infused at a rate of 125 mL/h; group 2, lactated Ringer's solution infused at a rate of 250 mL/h; group 3, 0.9% saline solution boosted with 5% glucose, infused at a rate of 125 mL/h. The primary outcome was labor length from enrollment until delivery. Between December 2010 and July 2015, 300 women were randomized to one of the three groups. Demographic and baseline obstetric characteristics were comparable between the groups. There was no significant difference in the time from enrollment to delivery (p = 0.62). Furthermore, there were no significant differences in second stage duration (p = 0.73), mode of delivery (p = 0.21), cord artery pH and glucose level between the groups. Increasing the intravenous volume of lactated Ringer's solution or substituting to fluid containing 5% glucose solution does not affect labor length.

    The increased pain at the latent phase can be associated with dysfunctional labor as well as increases in cesarean delivery frequency. We aimed to research the effect of the degree of pain at the time of epidural analgesia on the entire labor process including the mode of delivery. We performed epidural analgesia to 102 nulliparous women on patients' request. We divided the group into three based on NRS (numeric rating scale) at the moment of epidural analgesia; mild pain, NRS 1-4; moderate pain, NRS 5-7; severe pain, NRS 8-10. The primary outcome was the mode of delivery (normal labor or cesarean delivery). There were significant differences in the mode of delivery among groups. Patients with severe labor pain had a significantly higher cesarean delivery compared to patients with moderate labor pain (P = 0.006). The duration of the first and second stage of labor, fetal heart rate, use of oxytocin and premature rupture of membranes had no differences in the three groups. Our research showed that the degree of pain at the time of epidural analgesia request might influence the rate of cesarean delivery. Further research would be necessary for clarifying the mechanism that the augmentation of pain affects the mode of delivery.

    Full Text Available We examined pelvic floor muscles (PFM activity (%MVC in twenty nulliparous women by body position during exercise as well as the activation of abdominal muscles and the gluteus maximus during voluntary contractions of the PFMs. Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Activation of transversus abdominis, rectus abdominis, and gluteus maximus during voluntary PFM contractions was also assessed. Significant differences in mean normalized amplitudes of baseline PFM activity were revealed between standing and lying (P<0.00024 and lying and ball-sitting positions (P<0.0053. Average peak, average time before peak, and average time after peak did not differ significantly during the voluntary contractions of the PFMs. Baseline PFM activity seemed to depend on the body position and was the highest in standing. Pelvic floor muscles activity during voluntary contractions did not differ by position in continent women. Statistically significant differences between the supine lying and sitting positions were only observed during a sustained 60-second contraction of the PFMs.

    To assess obstetrical outcomes in a sample of nulliparous gestations with preeclampsia, as compared to gestations without preeclampsia, attended in the Enrique C. Sotomayor Hospital of Guayaquil, Ecuador. This was a comparative study of maternal and perinatal outcome data of gestations with late onset preeclampsia (n=150; gestational age=36.7±3.3 weeks) with that of normal gestations (n=150; gestational age 38.7±1.7 weeks). Almost three-quarters (73.3%) of preeclampsia cases were defined as severe. Compared to normal gestations, preeclampsia cases had higher anthropometric indices (neck and mid-arm circumference) and had more oligohydramnios, cesarean sections, transfusions, distressed fetuses, and adverse perinatal outcomes such as, lower Apgar scores at birth, and more preterm births, lower birth weight and small for gestational age infants. Gestations with preeclampsia had a negative impact on maternal and perinatal outcomes compared to gestations without preeclampsia. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    Because the lack of an induced pluripotent stem cell (iPSC) induction system with optimal safety and efficiency limits the application of these cells, development of such a system is important. To create such an induction system, we screened a variety of reprogrammed plasmid combinations and multiple compounds and then verified the system's feasibility using urine cells from different individuals. We also compared large-scale iPSC chromosomal variations and expression of genes associated with genomic stability between this system and the traditional episomal system using karyotype and quantitative reverse transcription polymerase chain reaction analyses. We developed a high-efficiency episomal system, the 6F/BM1-4C system, lacking tumorigenic factors for human urine-derived cell (hUC) reprogramming. This system includes six low-risk factors (6F), Oct4, Glis1, Klf4, Sox2, L-Myc, and the miR-302 cluster. Transfected hUCs were treated with four compounds (4C), inhibitor of lysine-demethylase1, methyl ethyl ketone, glycogen synthase kinase 3 beta, and histone deacetylase, within a short time period. Comparative analysis revealed significantly decreased chromosomal variation in iPSCs and significantly increased Sirt1 expression compared with iPSCs induced using the traditional episomal system. The 6F/BM1-4C system effectively induces reprogramming of urine cells in samples obtained from different individuals. iPSCs induced using the 6F/BM1-4C system are more stable at the cytogenetic level and have potential value for clinical application.

    Vertebral artery injury (VAI) during foraminal decompression in cervical spine surgery in the absence of repositioning or screw stabilization is rare. Without immediate recognition and treatment, it may have disastrous consequences. We aimed to describe the incidence and management of iatrogenic VAI in low-risk cervical spine surgery. The records of all patients who underwent surgical procedures of the cervical spine between January 2007 and May 2012 were retrospectively consecutively evaluated. Anterior cervical discectomy and fusion or arthroplasty as well as dorsal foraminal decompression through the Frykholm approach in degenerative diseases were defined as low-risk surgeries (n = 992). VAI occurred in 0.3 % (n = 3) of 992 procedures: in one case during a dorsal foraminal decompression, and in two cases during the anterior cervical discectomy and fusion (ACDF) of two or four levels, respectively. In the first case, the VAI was intraoperatively misdiagnosed. Despite an initially uneventful course, the patient suffered hemorrhage from a pseudoaneurysm of the injured VA 1 month after surgery. The aneurysm was successfully occluded by endovascular coiling. In both ACDF cases, angiography and endovascular stenting of the lacerated segment proceeded immediately after the surgery. All three patients suffered no permanent deterioration. In a high-volume surgical center, the incidence of VAI during low-risk cervical spine surgery is extremely low, comprising 0.3 % of all cases. The major risks are delayed sequels of the vessel wall laceration. In cases of VAI, immediate angiographic diagnostics and generous indications for endovascular treatment are obligatory.

    Assessing the likelihood of a variceal versus nonvariceal source of upper gastrointestinal bleeding (UGIB) guides therapy, but can be difficult to determine on clinical grounds. The objective of this study was to determine if there are easily ascertainable clinical and laboratory findings that can identify a patient as low risk for a variceal source of hemorrhage. This was a retrospective cohort study of adult ED patients with UGIB between January 2008 and December 2014 who had upper endoscopy performed during hospitalization. Clinical and laboratory data were abstracted from the medical record. The source of the UGIB was defined as variceal or nonvariceal based on endoscopic reports. Binary recursive partitioning was utilized to create a clinical decision rule. The rule was internally validated and test characteristics were calculated with 1,000 bootstrap replications. A total of 719 patients were identified; mean age was 55 years and 61% were male. There were 71 (10%) patients with a variceal UGIB identified on endoscopy. Binary recursive partitioning yielded a two-step decision rule (platelet count > 200 × 10 9 /L and an international normalized ratio [INR] low risk for a variceal source of hemorrhage. For the bootstrapped samples, the rule performed with 97% sensitivity (95% confidence interval [CI] = 91%-100%) and 49% specificity (95% CI = 44%-53%). Although this derivation study must be externally validated before widespread use, patients presenting to the ED with an acute UGIB with platelet count of >200 × 10 9 /L and an INR of low risk for a variceal source of their upper gastrointestinal hemorrhage. © 2017 by the Society for Academic Emergency Medicine.

    Purpose: Hemiablative therapy (HAT) is increasing in popularity for treatment of patients with low-risk prostate cancer (PCa). The validity of this therapeutic modality, which exclusively treats PCa within a single prostate lobe, rests on accurate staging. We tested the accuracy of unilaterally unremarkable biopsy findings in cases of low-risk PCa patients who are potential candidates for HAT. Methods and Materials: The study population consisted of 243 men with clinical stage ≤T2a, a prostate-specific antigen (PSA) concentration of <10 ng/ml, a biopsy-proven Gleason sum of ≤6, and a maximum of 2 ipsilateral positive biopsy results out of 10 or more cores. All men underwent a radical prostatectomy, and pathology stage was used as the gold standard. Univariable and multivariable logistic regression models were tested for significant predictors of unilateral, organ-confined PCa. These predictors consisted of PSA, %fPSA (defined as the quotient of free [uncomplexed] PSA divided by the total PSA), clinical stage (T2a vs. T1c), gland volume, and number of positive biopsy cores (2 vs. 1). Results: Despite unilateral stage at biopsy, bilateral or even non-organ-confined PCa was reported in 64% of all patients. In multivariable analyses, no variable could clearly and independently predict the presence of unilateral PCa. This was reflected in an overall accuracy of 58% (95% confidence interval, 50.6-65.8%). Conclusions: Two-thirds of patients with unilateral low-risk PCa, confirmed by clinical stage and biopsy findings, have bilateral or non-organ-confined PCa at radical prostatectomy. This alarming finding questions the safety and validity of HAT.

    Full Text Available BACKGROUND: Bladder cancer accounts for 5-10% of all cancers in Europe and up to 85% patients presents a noninvasive tumor, whose treatment of choice is the transurethral bladder resection (TURB paired with adjuvant intravesical chemotherapy or immunotherapy. Despite several clinical trials showed that this treatment is safe and decreases recurrences by 17% to 44% this practice is limited for many reasons. The study objective is to analyze the economical advantages of the single immediate post operative Mitomycin C instillation in Non Muscle-invasive Bladder Cancer (NMIBC low-risk patients.METHODS: A cost-benefit analysis was performed evaluating the economical gain that would raised from a scenario with a single immediate post operative mitomycin C instillation in each low-risk NMIBC patient who underwent to TURB. Net present value and cost-benefit ratio were calculated and sensitivity analyses were performed. Base case analysis was performed considering tumor recurrence rate reduction of 11.7% and a TURB costs of 2,167.0 €, while sensitivity analyses were performed using a recurrence rate reduction of 19.2% and 15.0% and a TURB cost of 2,472.93 €. The discount rate was 2%.RESULTS: The single immediate post operative instillation of mitomycin C resulted to be cost-beneficial with a cost-benefit ratio that goes from 0.48 to 0.79 when compared to TURB alone raising a Net Present Value that goes from 660,284.39 € to 2,650,530.79 €.CONCLUSION: This study demonstrates that even assuming conservative parameters for recurrence rates reduction, a single immediate post operative mitomycin C instillation in low risk NMIBC patients would lower not only the recurrence rate but also the caring cost for bladder cancer.

    Full Text Available Abstract Background The requirement to obtain written informed consent may undermine the potential of pragmatic randomized clinical trials (pRCTs to improve evidence-based care. This requirement could compromise trials statistical power or even force it to close them down prematurely. However, recent data from the U.S. and Spain suggest that a majority of the public endorses written consent for low-risk pRCTs. The present manuscript assesses whether this view is shared by patients. Methods This was a cross-sectional, probability-based survey, with a 2 × 2 factorial design, assessing support for written informed consent versus verbal consent or general notification for two low-risk pRCTs in hypertension, one comparing 2 drugs with similar risk/benefit profiles and the other comparing the same drug being taken in the morning or at night. This web-based survey was conducted in May 2016. Two-thousand and eight adults who were representative of the Spanish population participated in the survey (response rate: 61%. Of these 2008 respondents, 338 indicated that they had been diagnosed with hypertension and were being treated with prescription medicines for this condition at the time of responding to the survey. The primary outcome measures were respondents’ personal preference and recommendation to a research ethics committee regarding the use of written informed consent versus verbal consent or general notification. Results Overall, 74% of the 338 patient respondents endorsed written consent. In both scenarios, general notification received significantly more support (30.6%-44.7% than verbal consent (13.3%-17.6%. 43% of respondents preferred and/or recommended general notification rather than written consent. Conclusions As in the survey of the general public, more patients endorsed written consent than the alternative option. However, two factors suggest that a different approach to written consent should be investigated for low-risk pRCTs: a a

    Nasopharyngeal carcinoma (NPC) is rare among people of Indian ethnicity. A short retrospective case review of clinical records of Indian patients diagnosed with nasopharyngeal carcinoma in a period of 5 years was conducted. Their slides were further subjected to EBV encoded RNA (EBER) - In- situ Hybridization (ISH). The histologic subtype was nonkeratinizing carcinoma in all 4 patients. All were Epstein Barr Virus (EBV) positive. We believe that the crucial factor responsible for nasopharyngeal carcinoma is genetics; either a genetic susceptibility among high risk groups or genetic resistance/immunity in low risk groups. Further genetic studies are required to look for somatic or inherited chromosomal mutations among the various risk populations.

    Racial disparities in the incidence and risk profile of prostate cancer at diagnosis among African-American men are well reported. However, it remains unclear whether African-American race is independently associated with adverse outcomes in men with clinical low risk disease. We retrospectively analyzed the records of 895 men in the SEARCH (Shared Equal Access Regional Cancer Hospital) database in whom clinical low risk prostate cancer was treated with radical prostatectomy. Associations of African-American and Caucasian race with pathological biochemical recurrence outcomes were examined using chi-square, logistic regression, log rank and Cox proportional hazards analyses. We identified 355 African-American and 540 Caucasian men with low risk tumors in the SEARCH cohort who were followed a median of 6.3 years. Following adjustment for relevant covariates African-American race was not significantly associated with pathological upgrading (OR 1.33, p = 0.12), major upgrading (OR 0.58, p = 0.10), up-staging (OR 1.09, p = 0.73) or positive surgical margins (OR 1.04, p = 0.81). Five-year recurrence-free survival rates were 73.4% in African-American men and 78.4% in Caucasian men (log rank p = 0.18). In a Cox proportional hazards analysis model African-American race was not significantly associated with biochemical recurrence (HR 1.11, p = 0.52). In a cohort of patients at clinical low risk who were treated with prostatectomy in an equal access health system with a high representation of African-American men we observed no significant differences in the rates of pathological upgrading, up-staging or biochemical recurrence. These data support continued use of active surveillance in African-American men. Upgrading and up-staging remain concerning possibilities for all men regardless of race.

    Full Text Available Abstract OBJECTIVE Comparing foot length measurements of newborns in high and low risk pregnancies at a public hospital in Goiânia, GO, Brazil. METHOD A cross-sectional study carried out between April, 2013 and May, 2015, with a sample consisting of 180 newborns; 106 infants of women from high-risk pregnancies and 74 of women from low-risk pregnancies. Data were descriptively analyzed. Foot length measurement was performed using a stiff transparent plastic ruler, graduated in millimeters. The length of both feet was measured from the tip of the hallux (big toe to the end of the heel. RESULTS A statistically significant relationship was found between the foot length and newborn’s weight, between the cephalic and thoracic perimeters in the high-risk group and between the cephalic perimeter in the control group. CONCLUSION There is a need for creating cut-off points to identify newborns with intrauterine growth disorders using foot length.

  9. Ureteral diameter in low-risk vesicoureteral reflux in infancy and childhood

    Hellstroem, M.; Hjaelmaas, K.; Jacobsson, B.; Jodal, U.

    In order to improve the accuracy of the grading of vesicoureteral reflux (VUR), reference values for ureteral diameter at micturition cystourethrography (MCUG) were established in infants and children with low-risk VUR. Low-risk VUR was defined as VUR not associated with infection, obstruction, calculi, duplication, malformations (except for hypospadia) or neurogenic bladder disturbances. Forty-six children (age 1 day - 14 years) were selected by examining the records of 12000 MCUG:s performed 1960-1983. Ureteral diameter was measured at the widest point of the ureter on the films from MCUG:s and urographies. Ureteral diameter was slightly larger at MCUG than at urography in the same individuals but the difference was not significant. The ureteral diameter at MCUG also correlated closely to normal values at urography in a previous study. It is proposed that the reference values obtained at MCUG in the present investigation can be used for the differentiation between dilatation and no dilatation in the grading of VUR.

    Full Text Available Abstract Purpose Hypofractionated, stereotactic body radiotherapy (SBRT is an emerging treatment approach for prostate cancer. We present the outcomes for low-risk prostate cancer patients with a median follow-up of 5 years after SBRT. Method and Materials Between Dec. 2003 and Dec. 2005, a pooled cohort of 41 consecutive patients from Stanford, CA and Naples, FL received SBRT with CyberKnife for clinically localized, low-risk prostate cancer. Prescribed dose was 35-36.25 Gy in five fractions. No patient received hormone therapy. Kaplan-Meier biochemical progression-free survival (defined using the Phoenix method and RTOG toxicity outcomes were assessed. Results At a median follow-up of 5 years, the biochemical progression-free survival was 93% (95% CI = 84.7% to 100%. Acute side effects resolved within 1-3 months of treatment completion. There were no grade 4 toxicities. No late grade 3 rectal toxicity occurred, and only one late grade 3 genitourinary toxicity occurred following repeated urologic instrumentation. Conclusion Five-year results of SBRT for localized prostate cancer demonstrate the efficacy and safety of shorter courses of high dose per fraction radiation delivered with SBRT technique. Ongoing clinical trials are underway to further explore this treatment approach.

    To determine the prevalence of C677T and A1298C Single-nucleotide polymorphisms (SNPs) of the MTHFR gene in nulliparous women complicated with preeclampsia (PE). One hundred fifty gestations complicated with PE and their corresponding controls without the disease were recruited for the genotyping of C677T and A1298C polymorphisms of the MTHFR gene using restriction fragment length polymorphism polymerase chain reaction. Secondarily, homocysteine (HCy) plasma levels were measured in preeclamptic women displaying the CC genotype of the A1298C polymorphism (homozygous) and compared to HCy levels determined among controls with the normal AA genotype for the A1298C variant. Only the mutant CC genotype of the A1298C polymorphism was associated to higher risk of presenting PE, as frequency of this genotype was significantly higher among cases than controls (15.3% versus 0.7%, p A1298C polymorphism as compared to none among preeclamptics with a lower neck circumference (p = 0.0001). Women with the mutant CC A1298C SNP displayed higher plasma HCy levels as compared to controls with normal AA A1298C genotype (8.4 ± 2.6 versus 7.5 ± 2.7 mmoL/L p = 0.04). Prevalence of the CC mutant genotype of the A1298C polymorphism was higher among PE women. This mutation among PE women was related to increased neck circumference and higher HCy levels. Future research should aim at linking these gestational findings with obesity and cardiovascular risk.

    Optimal management of pregnancies at 39 weeks gestational age is unknown. Therefore, we sought to perform a comparative effectiveness analysis of elective induction of labor (eIOL) at 39 weeks among nulliparous women with non-anomalous singleton, vertex fetuses as compared to expectant management (EM) which included IOL for medical or obstetric indications or at 41 weeks in undelivered mothers. A Monte Carlo micro-simulation model was constructed modeling two mutually exclusive health states: eIOL at 39 weeks, or EM with IOL for standard medical or obstetrical indications or at 41 weeks if undelivered. Health state distribution probabilities included maternal and perinatal outcomes and were informed by a review of the literature and data derived from the Consortium of Safe Labor. Analyses investigating preferences for maternal versus infant health were performed using weighted utilities. Primary outcome was determining which management strategy posed less maternal and neonatal risk. Secondary outcomes were rates of cesarean deliveries, maternal morbidity and mortality, stillbirth, neonatal morbidity and mortality, and preferences regarding the importance of maternal and perinatal health. A management strategy of eIOL at 39 weeks resulted in less maternal and neonatal risk as compared to EM with IOL at 41 weeks among undelivered patients. Cesarean section rates were higher in the EM arm (35.9% versus 13.9%, p39 week eIOL still resulted in fewer cesarean deliveries as compared to EM (8.0% versus 26.1%, p39 week eIOL was favored over EM. Mathematical modeling revealed that eIOL at 39 weeks resulted in lower population risks as compared to EM with induction of labor at 41 weeks. Specifically, eIOL at 39 weeks resulted in a lower cesarean section rate, lower rates of maternal morbidity, fewer stillbirths and neonatal deaths, and lower rates of neonatal morbidity.

    The majority of chest pain admissions originate in the emergency department (ED). Despite a low incidence of cardiac events, limited telemetry availability, and its questionable benefit, these patients are routinely admitted to a monitored setting. The objectives were to analyze the cost-effectiveness of admission to telemetry versus admission to an unmonitored hospital bed in low-risk chest pain patients and explore when the use of telemetry may be cost-effective. The authors constructed a decision analytic model to evaluate the scenario of an ED admission of an otherwise healthy 55-year-old patient with low-risk chest pain defined as an acute coronary syndrome (ACS) probability of 2%. Costs were estimated from 2009 Medicare data for hospital reimbursement and physician services, as well as published data on disability costs. Published studies were used to estimate the risk of ACS, cardiac arrest, time to defibrillation, survival, long-term disability, and quality of life. In the base case, telemetry was more effective (0.0044 quality-adjusted life-years [QALYs]) but more costly ($299.67) than a floor bed, resulting in a high marginal cost-effectiveness ratio (mCER) of $67,484.55 per QALY. In comprehensive sensitivity analyses, the mCER crossed below the willingness-to-pay (WTP) threshold of $50,000 per QALY when the following scenarios were met: the probability of ACS exceeds 3%, the probability of cardiac arrest is greater than 0.4%, the probability of shockable dysrhythmia is above 83%, the probability of delay in telemetry bed availability is below 52%, and the opportunity cost of delay to telemetry bed placement is below $119. Telemetry may be a "cost-effective" use of health care resources for chest pain patients when patients have a probability of ACS above 3% or for patients with a minimal delay and cost associated with obtaining a monitored bed. Further research is needed to better stratify low-risk chest pain patients to the appropriate inpatient setting

    Full Text Available Objective To analyze and compare occurrence of adverse immediate neonatal outcomes in high and low-risk obstetrical population. Methods Retrospective cohort study of 2370 pregnant women. The odds of adverse outcomes (i.e. low Apgar score (1–4 points and intermediate Apgar score (5–8 points at 1 and 5 minutes of life, birth to a small-for-gestational-age neonate (below 90th percentile of birth weight, and requirement for advanced level II-III nursery care as well as odds of primary cesarean delivery–-were analyzed using logistic regression analysis. Results All of the studied outcomes were seen more often among the high-risk patients. When the outcomes were analyzed within a given group some interesting observations were made. The highest odds of abnormal Apgar scores (when compared to the low risk population were seen in patients with preeclampsia–-6.06 (95% CI 3.28; 11.22 and twin pregnancies–-odds ratio of 6.63 (95% CI 2.24; 19.67. Among Small-for-Gestational-Age newborns the most frequently identified maternal condition was preeclampsia (21.57%, out of all fetal conditions twin gestation (26.67% was number one identified scenario. The highest proportion of patients requiring advanced level nursery care (level II and III was observed in those with twin gestation, pregnancies complicated by hypertension with and without diabetes. The highest odds of having primary cesarean delivery in laboring patients (when compared to the low risk population were seen in the patients with IUGR fetus–-odds ratio of 26.78 [95% CI 7.65; 93.75], followed by macrosomia–-odds ratio 5.74 [95% CI 2.14; 15.41], preeclampsia–-odds ratio 5.52 [95% CI 3.14; 9.69].

    Pragmatic randomized clinical trials (pRCTs) collect data that have the potential to improve medical care significantly. However, these trials may be undermined by the requirement to obtain written informed consent, which can decrease accrual and increase selection bias. Recent data suggest that the majority of the US public endorses written consent for low-risk pRCTs. The present study was designed to assess whether this view is specific to the US. The study took the form of a cross-sectional, probability-based survey, with a 2 × 2 factorial design, assessing support for written informed consent vs. verbal consent or general notification for two low-risk pRCTs in hypertension, one comparing two drugs with similar risk/benefit profiles and the other comparing the same drug being taken in the morning or at night. The primary outcome measures were respondents' personal preference and hypothetical recommendation to a research ethics committee regarding the use of written informed consent vs. the alternatives. A total of 2008 adults sampled from a probability-based online panel responded to the web-based survey conducted in May 2016 (response rate: 61%). Overall, 77% of respondents endorsed written consent. In both scenarios, the alternative of general notification received significantly more support (28.7-37.1%) than the alternative of verbal consent (12.7-14.0%) (P = 0.001). Forty per cent of respondents preferred and/or recommended general notification rather than written consent. The results suggested that, rather than attempting to waive written consent, current pRCTs should focus on developing ways to implement written consent that provide sufficient information without undermining recruitment or increasing selection bias. The finding that around 40% of respondents endorsed general notification over written consent raises the possibility that, with educational efforts, the majority of Spaniards might accept general notification for low-risk pRCTs. © 2017 The

    The current study built upon previous research that predicted with 90.7% accuracy which patients presenting with acute low-back pain go on to develop chronic disability problems. Fifty-seven patients were classified as high risk (HR) or low risk (LR) according to a predictive algorithm, and were evaluated with a variety of psychosocial measures. Overall, HR patients had more Axis I pathology than LR patients, and used poorer coping styles. Logistic regression analyses identified variables that differentiated, with 80% accuracy, between the HR and LR patients. The results highlight the importance of identifying patients who are at risk for developing chronic pain following acute injury so that prophylactic intervention can be offered before chronic pain disability status becomes entrenched.

    The oncogenic potential of papillomaviruses (PVs) has been appreciated since the 1930s yet the mechanisms of virally-mediated cellular transformation are still being revealed. Reasons for this include: a) the oncoproteins are multifunctional, b) there is an ever-growing list of cellular interacting proteins, c) more than one cellular protein may bind to a given region of the oncoprotein, and d) there is only limited information on the proteins encoded by the corresponding non-oncogenic PVs. The perspective of this review will be to contrast the activities of the viral E6 and E7 proteins encoded by the oncogenic human PVs (termed high-risk HPVs) to those encoded by their non-oncogenic counterparts (termed low-risk HPVs) in an attempt to sort out viral life cycle-related functions from oncogenic functions. The review will emphasize lessons learned from the cell culture studies of the HPVs causing mucosal/genital tract cancers. PMID:22284986

    Prenatal health care is pivotal in providing adequate prevention and care to pregnant women. We examined the determinants of inadequate prenatal health care utilisation by low-risk women in primary midwifery-led care in the Netherlands. We used longitudinal data from the population-based DELIVER study with 20 midwifery practices across the Netherlands in 2009 and 2010 as the experimental setting. The participants were 3070 pregnant women starting pregnancy care in primary midwifery care. We collected patient-reported data on potential determinants of prenatal care utilisation derived from the Andersen model. Prenatal health care utilisation was measured by a revised version of the Kotelchuck Index, which measures a combination of care entry and number of visits. Low-risk pregnant women (not referred during pregnancy) were more likely to use prenatal care inadequately if they intended to deliver at a hospital, if they did not use folic acid adequately periconceptionally, or if they were exposed to cigarette smoke during pregnancy. Among those who were referred to secondary care, women reporting a chronic illnesses or disabilities, and women who did not use folic acid periconceptionally were more likely to make inadequate use of prenatal care. Inadequate prenatal health care use in primary midwifery care is more likely in specific groups, and the risk groups differ when women are referred to secondary care. The findings suggest routes that can target interventions to women who are at risk of not adequately using prenatal prevention and care services. Copyright © 2015 Australian College of Midwives.

    Methods: A retrospective cohort study was conducted on patients with GTN who were referred to Firoozgar and Mirza Koochak Khan teaching hospitals during 10 years, starting from 2004. The inclusion criterion was patients with low-risk persistent GTN after molar pregnancy, EP, and abortion, that treated with single agent chemotherapy actinomycin-D. After following the patients for 12 months, patients with serum βHCG lower than 5 mIU/ml, who intended to have child were allowed to become pregnant. The following items were observed in the study: age, body mass index (BMI, parity, chemotherapy duration, and pregnancy outcomes such as spontaneous abortion or preterm labor, pre-eclampsia, stillbirth, fetal malformation, and repeated molar pregnancy. Results: 74 patients were monitored, 83.78% of them had uncomplicated pregnancy and labor, 4.05% had the abortion, 4.05% had second molar pregnancy, 2.7% had pre-eclampsia, 5.40% had preterm labor. Moreover, stillbirth and malformation did not occur in this study even after chemotherapy treatment. There was not any significant correlation between age, BMI, parity, and chemotherapy duration with pregnancy outcomes. Conclusion: The outcomes of pregnancy after chemotherapy with actinomycin-D is similar to the general population who did not have chemotherapy. The abortion rate and repeated molar pregnancy were similar between population and sample too. Thus, the study shows that the cured patients with low-risk GTN have as much chance of having a normal pregnancy as normal women. In other words, treatment with actinomycin-D does not have any adverse effect in future pregnancies.

    International guidelines have set the frame and methods of patients' surveillance after early breast cancer (BC) treatment. Since 1998, delegation of low-risk BC patients follow-up to nonhospital practitioners has been developed within a care network in the Paris region. We used the Gynecomed care network digital database to describe the characteristics of oncological events which occurred in the cohort, and to assess the quality of BC follow-up in relapsing patients. Events were defined as any local, contralateral, or metastatic recurrence, as well as second cancer or death due to any cause. We developed a ranked evaluation method of our surveillance program. Among the 3019 patients followed in the network, 116 (4.3%) patients had 116 events. Median follow-up was 7.1 years (0-51). First events were local-regional relapses, contralateral BCs, metastatic events, second primaries in respectively 52, 26, 14, 24 cases. During the first 5 years, 68.4% of surveillance visits were performed on time, 13.5% were behind schedule and 18.1% were not performed, while 79.1% of mammographies were performed on time, 7.7% behind schedule, and 13.2% were not performed. On schedule examinations allowed diagnosis of 77% of the local-regional, ipsilateral relapses or contralateral BCs, including 38 (69%) discovered by mammographies and 17 (31%) by clinical examination. A nonhospital practitioner care network is able to comply with good surveillance practices and deliver high quality surveillance, in accordance with international guidelines. Delegation of low-risk BC surveillance to nonhospital practitioners is reliable. © 2017 Wiley Periodicals, Inc.

    To evaluate the risk of low-risk prostate cancer or prostate cancer that may benefit from surveillance in patients with a PSA level less than 10 ng/ml, a normal digital rectal examination (DRE) and a transrectal power Doppler sonography (PDS) without anomaly. Two hundred and forty-three consecutive patients with a PSA level less than 10 ng/ml and a DRE without anomaly had PDS-guided biopsies: 12 to 15 samples were systematically taken and echo-guided in the suspect areas. The PDS results were rated from 1 to 4: 1: normal, 2: slightly hypoechogenic avascular area in which the hypo-echogenicity disappears after compression by probe, 3: hypoechogenic avascular area, 4: hypoechogenic vascularised area with power Doppler sonography. Patients rated 3 or 4 were considered to be pathological. D'Amico's criteria were used to assess the risk of a biological recurrence after treatment and those of Dall'Era were used to select the patients that could benefit from active surveillance (AS). The PDS was considered to be a true positive if at least one biopsy was positive in the same sextant as the suspect image. In a prospective manner, 106 cancers were diagnosed that could be qualified as low-risk in 84% of the cases (89% with a normal PDS and 79% with an abnormal PDS). Sixty-nine percent of the cases could be subject to AS (86% of the normal PDS cases and 47% of the abnormal PDS cases; PVPN=95%) (P=0.015). A normal PDS in patients presenting a PSA level less than 10 ng/ml and a DRE without anomaly may be used to put off the indication for a biopsy in order to reduce their number as well as the risks of overtreatment for a latent cancer.

    2007-09-01

    Full Text Available Abstract Background Neuroblastoma (NB is the most common extracranial solid tumour of childhood. Several genomic imbalances correlate to prognosis in NB, with structural rearrangements, including gene amplification, in a near-diploid setting typically signifying high-risk tumours and numerical changes in a near-triploid setting signifying low-risk tumours. Little is known about the temporal sequence in which these imbalances occur during the carcinogenic process. Methods We have reconstructed the appearance of cytogenetic imbalances in 270 NBs by first grouping tumours and imbalances through principal component analysis and then using the number of imbalances in each tumour as an indicator of evolutionary progression. Results Tumours clustered in four sub-groups, dominated respectively by (1 gene amplification in double minute chromosomes and few other aberrations, (2 gene amplification and loss of 1p sequences, (3 loss of 1p and other structural aberrations including gain of 17q, and (4 whole-chromosome gains and losses. Temporal analysis showed that the structural changes in groups 1–3 were acquired in a step-wise fashion, with loss of 1p sequences and the emergence of double minute chromosomes as the earliest cytogenetic events. In contrast, the gains and losses of whole chromosomes in group 4 occurred through multiple simultaneous events leading to a near-triploid chromosome number. Conclusion The finding of different temporal patterns for the acquisition of genomic imbalances in high-risk and low-risk NBs lends strong support to the hypothesis that these tumours are biologically diverse entities, evolving through distinct genetic mechanisms.

    To identify risk factors for fear of childbirth (FOC) according to parity and socioeconomic status, and to evaluate associations between FOC and adverse perinatal outcomes. A cohort study. The Finnish Medical Birth Register. All 788 317 singleton births during 1997-2010 in Finland. Fear of childbirth was defined according to the International Classification of Diseases code O99.80, and its associations with several risk factors and perinatal outcomes were analysed by multivariable logistic regression. Prevalence of, risk factors for and outcomes of FOC. Fear of childbirth was experienced by 2.5% of nulliparous women and 4.5% of multiparous women. The strongest risk factors for FOC in nulliparous women were depression [adjusted odds ratio (aOR), 6.35; 95% confidence interval (CI), 5.25-7.68], advanced maternal age (aOR, 3.78; 95% CI, 3.23-4.42) and high or unspecified socioeconomic status. In multiparous women, the strongest risk factors for FOC were depression (aOR, 5.47; 95% CI, 4.67-6.41), previous caesarean section (CS) (aOR, 3.02; 95% CI, 2.93-3.11) and high or unspecified socioeconomic status. Among both nulliparous and multiparous women, FOC was associated with higher rates of CS (3.3-fold and 4.5-fold higher, respectively) and a lower incidence of low birthweight (depression are predisposing factors for FOC regardless of parity. Among multiparous women, a previous CS increases vulnerability to FOC. FOC is associated with increased rates of CS, but does not adversely affect other pregnancy outcomes. © 2014 Royal College of Obstetricians and Gynaecologists.

    To determine the optimal timing of vaginal misoprostol administration in nulliparous women undergoing office hysteroscopy. Randomized double-blind placebo-controlled study. University teaching hospital. One hundred twenty nulliparous patients were randomly allocated in a 1:1 ratio to the long-interval misoprostol group or the short-interval misoprostol group. In the long-interval misoprostol group, two misoprostol tablets (400 μg) and two placebo tablets were administered vaginally at 12 and 3 hours, respectively, before office hysteroscopy. In the short-interval misoprostol group, two placebo tablets and two misoprostol tablets (400 μg) were administered vaginally 12 and 3 hours, respectively, before office hysteroscopy. The severity of pain was assessed by the patients with the use of a 100-mm visual analog scale (VAS). The operators assessed the ease of the passage of the hysteroscope through the cervical canal with the use of a 100-mm VAS as well. Pain scores during the procedure were significantly lower in the long-interval misoprostol group (37.98 ± 13.13 vs. 51.98 ± 20.68). In contrast, the pain scores 30 minutes after the procedure were similar between the two groups (11.92 ± 7.22 vs. 13.3 ± 6.73). Moreover, the passage of the hysteroscope through the cervical canal was easier in the long-interval misoprostol group (48.9 ± 17.79 vs. 58.28 ± 21.85). Vaginal misoprostol administration 12 hours before office hysteroscopy was more effective than vaginal misoprostol administration 3 hours before office hysteroscopy in relieving pain experienced by nulliparous patients undergoing office hysteroscopy.

    Full Text Available A recent randomised controlled trial (RCT demonstrated that induction of labour at 39 weeks of gestational age has no short-term adverse effect on the mother or infant among nulliparous women aged ≥35 years. However, the trial was underpowered to address the effect of routine induction of labour on the risk of perinatal death. We aimed to determine the association between induction of labour at ≥39 weeks and the risk of perinatal mortality among nulliparous women aged ≥35 years.We used English Hospital Episode Statistics (HES data collected between April 2009 and March 2014 to compare perinatal mortality between induction of labour at 39, 40, and 41 weeks of gestation and expectant management (continuation of pregnancy to either spontaneous labour, induction of labour, or caesarean section at a later gestation. Analysis was by multivariable Poisson regression with adjustment for maternal characteristics and pregnancy-related conditions. Among the cohort of 77,327 nulliparous women aged 35 to 50 years delivering a singleton infant, 33.1% had labour induced: these women tended to be older and more likely to have medical complications of pregnancy, and the infants were more likely to be small for gestational age. Induction of labour at 40 weeks (compared with expectant management was associated with a lower risk of in-hospital perinatal death (0.08% versus 0.26%; adjusted risk ratio [adjRR] 0.33; 95% CI 0.13-0.80, P = 0.015 and meconium aspiration syndrome (0.44% versus 0.86%; adjRR 0.52; 95% CI 0.35-0.78, P = 0.002. Induction at 40 weeks was also associated with a slightly increased risk of instrumental vaginal delivery (adjRR 1.06; 95% CI 1.01-1.11, P = 0.020 and emergency caesarean section (adjRR 1.05; 95% CI 1.01-1.09, P = 0.019. The number needed to treat (NNT analysis indicated that 562 (95% CI 366-1,210 inductions of labour at 40 weeks would be required to prevent 1 perinatal death.

    Rates of cesarean section increase worldwide, and the components of this increase are partially unknown. A strong role is prescribed to dystocia, and at the same time, the diagnosis of dystocia is highly subjective. Previous studies indicated that risk of cesarean is higher when women are admitted to the hospital early in the labor. We examined data on 1,202 nulliparous women with singleton, vertex pregnancies and spontaneous labor onset. We selected three groups based on cervical dilatation at admission: early (0.5-1.5 cm, N = 178), intermediate (2.5-3.5 cm, N = 320), and late (4.5-5.5 cm, N = 175). The Kaplan-Meier estimator was used to analyze the risk of delivery by cesarean section at a given dilatation, and thin-plate spline regression with a binary outcome (R library gam) to assess the form of the associations between the cesarean section in either the first or second stage versus vaginal delivery and dilatation at admission. Women who were admitted to labor early had a higher risk of delivery by cesarean section (18 versus 4% in the late admission group), while the risk of instrumental delivery did not differ (24 versus 24%). Before 4 cm dilatation, the earlier a woman was admitted to labor, the higher was her risk of delivery by cesarean section. After 4 cm dilatation, however, the relationship disappeared. These patterns were true for both first and second stage cesarean deliveries. Oxytocin use was associated with a higher risk of cesarean section only in the middle group (2.5-3.5 cm dilatation at admission). Early admission to labor was associated with a significantly higher risk of delivery by cesarean section during the first and second stages. Differential effects of oxytocin augmentation depending on dilation at admission may suggest that admission at the early stage of labor is an indicator rather than a risk factor itself, but admission at the intermediate stage (2.5-3.5 cm) becomes a risk factor itself.

    Acute upper gastrointestinal haemorrhage is a common medical emergency, initially managed with inpatient care. Bleeding stops spontaneously in over 80% of cases, indicating that patients with low-risk upper gastrointestinal haemorrhage may be more optimally managed in the community, without the need for admission to hospital. To assess the safety of managing patients with low-risk upper gastrointestinal haemorrhage without admission to hospital. Prospective/retrospective study of all patients presenting to a UK teaching hospital with low-risk upper gastrointestinal haemorrhage who were managed without admission to hospital over 5 years. Low risk was defined as Glasgow Blatchford Score of 2 or less, age below 70 years, no other active medical problems, not taking warfarin and suspected nonvariceal bleed. Outcome measures were the need for intervention (blood transfusion, endoscopic therapy or surgery) and death. One hundred and forty-two patients fulfilled the inclusion criteria, and were managed without admission to hospital. No patients required endoscopic intervention, blood transfusion or surgery. The 28-day mortality was nil. Forty-one patients had normal endoscopic examination and 11 had significant endoscopic findings (peptic ulceration=10, oozing Mallory-Weiss tear=1) but did not require intervention. Patients presenting with a primary upper gastrointestinal haemorrhage aged below 70 years with a Glasgow Blatchford Score of 2 or less are at a low risk, and can be safely managed in the community.

    Personalised health-risk assessment is one of the most common components of health promotion programs. Previous research on responses to health risk feedback has commonly focused on the reception of bad news (high-risk feedback). The reception of low-risk feedback has been comparably neglected since it is assumed that good news is reassuring and readily received. However, field studies suggest mixed responses to low-risk health feedback. Accordingly, we examine whether pre-feedback risk expectancies can mitigate the reassuring effects of good news. In two studies (N = 187, N = 565), after assessing pre-feedback risk expectancies, participants received low-risk personalised feedback about their own risk of developing (the fictitious) Tucson Chronic Fatigue Syndrome (TCFS). Study 2 also included peer TCFS risk status feedback. Afterwards, self- and peer-related risk perception for TCFS was assessed. In both studies, participants who expected to be at high risk but received good news (unexpected low-risk feedback) showed absolute lack of reassurance. Specifically, they felt at significantly greater TCFS risk than participants who received expected good news. Moreover, the unexpected low-risk group even believed that their risk was as high as (Study 1) or higher (Study 2) than that of their peers (comparative lack of reassurance). Results support the notion that high pre-feedback risk expectancies can mitigate absolute and comparative reassuring effects of good news. © 2016 The International Association of Applied Psychology.

    Full Text Available BACKGROUND: The role of frozen section (FS in intraoperative decision making for surgical staging of endometrial cancer is controversial. Objective of this study is to assess the agreement rate between the FS and paraffin section (PS; and the potential impact of the role of FS in the intra-operative decision making for the complete surgical staging in low risk endometrial cancer. METHODS: This is a retrospective analysis of patients diagnosed with intra-operative FS stage I, grade I or II endometrial cancer from 1995-2004. FS results were compared with final pathology results with regard to tumor grade, depth of myometrial invasion, cervical involvement, lymphovascular invasion, and lymph node involvement. Agreement statistic with kappa was calculated using SPSS statistical software. Categorical variables were tested using chi-square test with p value of ≤0.05 being statistically significant. RESULTS: Of the 457 patients with endometrial cancer, 146 were evaluated by intra-operative FS and met inclusion criteria. FS results were in disagreement with permanent section in 35% for the grade (kappa 0.58, p = 0.003, 28% for depth of myometrial invasion (kappa 0.61, p<0.0001, 13% for cervical involvement (kappa 0.78, p = 0.002, and 32% for lymphovascular invasion (kappa 0.6, p = 0.01. Permanent pathology upstaged 31.9% & 23.2% of FS stage IA, & IB specimen respectively. Lymph node dissection was done in 56.8%. Lymph node metastasis was identified in 8.4%. Use of intraoperative FS would have resulted in suboptimal surgical treatment in 13% stage IA and 6.6% of stage IB patients respectively by foregoing lymphadenectomy. CONCLUSION: A significant number of patients with low risk endometrial cancer by FS were upstaged and upgraded on final pathology. Before placing absolute reliance on intraoperative FS to undertake complete surgical staging, the inherent limitation of the same in predicting final stage and grade highlighted by our data

    After thyroidectomy, the goal of the first dose of radioactive iodine (RAI) is remnant ablation to facilitate the initial staging with the post-therapy scan and to facilitate the early detection of recurrences. The purpose of this study is to the survival benefit of RAI in low-risk thyroid cancer patients. Using Cancer thyroid registry of Marne Ardennes (1041 patients) and hospital data base of centre Leclerc (257 patients), we included all differentiated thyroid cancer (DTC) patients at low risk from 1975 to 2005. Median follow-up was 10.3 years, during which 19 recurrences, 61 other malignant diseases and 105 deaths were registered. 387 patients (30%) received no RAI and 911 had RAI (70%). If we confirmed that some clinical characteristics were associated with RAI intake, the study failed to demonstrate any survival benefit of RAI in low risk DTC patients

    To assess whether performance indicators based on administrative hospital data can be rendered more useful by stratifying them according to risk status of the patient. Retrospective analysis of 10 years of administrative hospital data for patients with acute myocardial infarction (AMI). Four risk groups defined by cross-classifying patient age (Australia, with more than 50 AMI admissions annually. 21,537 patients admitted through the emergency department and subsequently diagnosed as having AMI. Systematic variation in standardised case fatality ratios. Systematic variation is the variation across hospitals after accounting for the Poisson variation in the number of deaths at each hospital. It was obtained from an empirical-Bayes model. Case fatality ratios were standardised according to the age, sex and risk factor profile of the patient. Systematic variation decreased monotonically across the four risk groups as case fatality increased (likelihood ratio test: chi(2) = 8.08, df = 1, p = 0.004). Systematic variation was largest and statistically significant (0.375; 95% CI 0.144 to 0.606) for low-risk patients (<75 years with no risk conditions; case fatality rate = 2.0%) but was smallest (0.126; 0.039 to 0.212) for high-risk patients (75+ years with at least one risk condition; case fatality rate = 24.3%). Analysis of data from high-risk patients with AMI provides little opportunity to identify better-performing hospitals because there is relatively little variation across hospitals. In such patients, older age and comorbid illness are probably more important than quality of care in determining outcomes. In contrast, for low-risk patients the systematic variation was large suggesting that outcomes for such patients are more sensitive to clinical error. Analysing data for low-risk patients maximises our ability to identify best-performing hospitals and learn from their processes and structures to effect system-wide changes that will benefit all patients.

    Background: Using non-pharmacological pain relief methods for reducing labor pain has always been one of the major concerns in obstetrics and gynecology. Objective: Comparing the effects of aromatherapy with jasmine and salvia on pain severity and labor outcome in nulliparous women. Materials and Methods: In this randomized clinical trial, 156 nulliparous women in labor were randomly selected and divided into salvia, jasmine, and control groups (52 in each group). The study duration was 6 months (from October 2009 to March 2010). Each group underwent aromatherapy using an incense mask for 15 min (distilled water for the control group). Pain severity was measured before and 30 and 60 min after the incense aromatherapy. Also, duration of the first and second stages of labor, first- and fifth-minute APGAR scores of the baby, and the frequency of labor type were measured and recorded in each group. Results: In comparison to the other groups, pain severity and duration of the first and second stages of labor were significantly lower in the aromatherapy group of salvia 30 min after the intervention (P = 0.001). However, no significant difference was found among the three groups regarding pain severity 60 min after the aromatherapy, first- and fifth-minute APGAR scores of the baby, and the frequency of labor type. Conclusions: The results of the present study indicated that aromatherapy with saliva had beneficial effects on pain relief, shortened the labor stages, and had no negative impact on the baby's APGAR score.

    The objectif was to evaluate ultrasound measurement of the opening of the internal cervical os in the prediction of cervical ripening and to compare it with Bishop's score. We conducted a prospective study of 77 nulliparous women admitted to hospital in labor at 41w gestation, with Bishop's Score os was performed using transvaginal ultrasound and Bishop's score was determined by clinical examination. All patients received prostaglandins for cervical ripening. Cervical ripening was successful among 63 patients (81%). Bishop's score and the opening of the internal cervical os were statistically associated with the success or failure of cervical ripening. The success rate of cervical ripening was 100% when the opening of the internal cervical os was equal to or greater than 5 mm (sensitivity: 54%, specificity: 86%). ROC curves showed that the measurement of the internal cervical os was more predictive of cervical ripening than Bishop's score (area under the curve: 0.733 and 0.704 respectively). Compared to Bishop's score, echographic measurement of the opening of the internal cervical os is more predictive of the success of cervical ripening in nulliparous women at 41 weeks of pregnancy with an unfavourable cervix.

    The aim of this study was to evaluate the effect of inflatable obstetric belts on uterine fundal pressure in the management of the second stage of labor. Between July 2009 and December 2010, 188 nulliparous women with a singleton pregnancy at term were enrolled and only one dropped. The participants were randomized to receive either standard care (control group, n = 91) or uterine fundal pressure by the Labor Assister (Baidy M-520/Curexo, Inc., Seoul, Korea; active group, n = 97) during the second stage of labor in addition to standard care. The Labor Assister is an inflatable obstetric belt that is synchronized to apply constant fundal pressure during a uterine contraction. The primary endpoint was duration of the second stage of labor in women who delivered vaginally (control, n = 80 versus active, n = 93). It was not analyzed in women who delivered by cesarean section (n = 14) and delivered precipitously (n = 1). The secondary outcomes are perinatal outcomes and perineal laceration. Participants received patient-controlled epidural analgesia. The 93 women in the active group spent less time in the second stage of labor when compared to the 80 women in the control group (46.51 ± 28.01 min versus 75.02 ± 37.48 min, p labor without complications in nulliparous women who receive patient-controlled epidural analgesia.

    Vaccines are one of the most important public health interventions. Understanding factors associated with vaccine acceptance is critical. The objectives of this study were to evaluate the impact of the three constructs of the Theory of Planned Behavior (TPB) on the intention to be vaccinated among healthy individuals being seen for pre-travel care, and to evaluate if behavioral intention was associated with vaccine acceptance. We surveyed individuals seeking vaccination at the University of Louisville Vaccine and International Health and Travel Clinic. Linear and two stage least squares regression models were used to define the associations between constructs of the TPB and the intention to be vaccinated, as well as the association between the intention to be vaccinated and vaccine acceptance. A total of 183 individuals were included in the analysis. None of the constructs of the TPB were associated with intention to be vaccinated. Behavioral intention was not associated with vaccination acceptance. This study suggests that the TPB does not predict the intention to get vaccinated among individuals attending our Vaccine and International Health and Travel Clinic. It will be critical to define better predictors of vaccine uptake in healthy, low-risk individuals to increase vaccine acceptance.

    Full Text Available OBJECTIVE: Blood donors in Brazil have been routinely screened for HTLV-I/II since 1993. A study was performed to estimate the prevalence of HTLV-I/II infection in a low risk population and to better understand determinants associated with seropositivity. METHODS: HTLV-I/II seropositive (n=135, indeterminate (n=167 and seronegative blood donors (n=116 were enrolled in an open prevalence prospective cohort study. A cross-sectional epidemiological study of positive, indeterminate and seronegative HTLV-I/II subjects was conducted to assess behavioral and environmental risk factors for seropositivity. HTLV-I/II serological status was confirmed using enzyme-linked immunosorbent assay (EIA and Western blot (WB. RESULTS: The three groups were not homogeneous. HTLV-I/II seropositivity was associated to past blood transfusion and years of schooling, a marker of socioeconomic status, and use of non-intravenous illegal drugs. CONCLUSIONS: The study results reinforce the importance of continuous monitoring and improvement of blood donor selection process.

    Diagnosis of malaria using only clinical means leads to overdiagnosis. This has implications due to safety concerns and the recent introduction of more expensive drugs. Temperature is a major climatic factor influencing the transmission dynamics of malaria. This study looked at trends in malaria morbidity in the low risk Kenyan district of Nyandarua, coupled with data on temperature and precipitation for the years 2003-2006. July had the highest number of cases (12.2% of all cases) followed by August (10.2% of all cases). July and August also had the lowest mean maximum temperatures, 20.1 and 20.2 °C respectively. April, July and August had the highest rainfall, with daily means of 4.0, 4.3 and 4.9 mm, respectively. Observation showed that the coldest months experienced the highest number of cases of malaria. Despite the high rainfall, transmission of malaria tends to be limited by low temperatures due to the long duration required for sporogony, with fewer vectors surviving. These cold months also tend to have the highest number of cases of respiratory infections. There is a possibility that some of these were misdiagnosed as malaria based on the fact that only a small proportion of malaria cases were diagnosed using microscopy or rapid diagnostic tests. We conclude that overdiagnosis may be prevalent in this district and there may be a need to design an intervention to minimise it.

    A number of sources suggest changes in anxiety across the transition to parenthood may be experienced by parents in different ways, yet no studies have examined whether new parents experience changes in anxiety in distinct subgroups. We conducted a longitudinal study of 208 first-time parents (104 couples) from a low-risk population. Parents were interviewed from the third trimester of pregnancy to nine-months postpartum. The current study utilized latent class growth analysis to explore subgroups of change in symptoms of anxiety. Based on stress and coping theory, we also examined a number of personal and social prenatal predictors of subgroup membership. We identified two distinct change trajectories: (1) moderate and stable and (2) low and declining. We also found prenatal depression, expected parenting efficacy, and relationship satisfaction were significantly associated with subgroup membership. Our results suggest a majority of new parents adjust well to parenthood in terms of anxiety, while a smaller subgroup of parents experience continually higher levels of anxiety months after the baby is born.

    Checking the first 70 low risk liver transplantation performed in our hospital, who did not receive prophylaxis for Cytomegalovirus, we found that the incidence of Cytomegalovirus-infection and Cytomegalovirus-disease were 47% and 16% respectively. For this reason we started a prospective, open clinical study, to address the safety of acyclovir prophylaxis in low-risk liver transplant patients. Seventy patients did not receive acyclovir. Fifty patients received oral acyclovir during 3 months (800-3,200 mg/day). The occurrence of Cytomegalovirus infection was not modified (40%) but Cytomegalovirus disease decreased dramatically (4%, p Varicela-zoster symptomatic disease in this group of patients.

    Comparing foot length measurements of newborns in high and low risk pregnancies at a public hospital in Goiânia, GO, Brazil. A cross-sectional study carried out between April, 2013 and May, 2015, with a sample consisting of 180 newborns; 106 infants of women from high-risk pregnancies and 74 of women from low-risk pregnancies. Data were descriptively analyzed. Foot length measurement was performed using a stiff transparent plastic ruler, graduated in millimeters. The length of both feet was measured from the tip of the hallux (big toe) to the end of the heel. A statistically significant relationship was found between the foot length and newborn's weight, between the cephalic and thoracic perimeters in the high-risk group and between the cephalic perimeter in the control group. There is a need for creating cut-off points to identify newborns with intrauterine growth disorders using foot length.

Taking NSAIDs/aspirin reduced 30-day mortality, OR 0.22 (CI: 0.08–0.60. Conclusion. PERS identifies 10.8% of those with UGIH as low risk but 35.7% required intervention or died. It has a limited role in assessing these patients and should not be used to identify those suitable for outpatient endoscopy.

    The aim of this study was to report the feasibility of volumetric-modulated arc therapy (VMAT) in the postoperative irradiation of the vaginal vault. Moreover, the VMAT technique was compared with 3D conformal radiotherapy (3D-CRT) and fixed-field intensity-modulated radiotherapy (IMRT), in terms of target coverage and organs at risk sparing. The number of monitor units and the delivery time were analyzed to score the treatment efficiency. All plans were verified in a dedicated solid water phantom using a 2D array of ionization chambers. Twelve patients with endometrial carcinoma who underwent radical hystero-adenexectomy and fixed-field IMRT treatments were retrospectively included in this analysis; for each patient, plans were compared in terms of dose-volume histograms, homogeneity index, and conformity indexes. All techniques met the prescription goal for planning target volume coverage, with VMAT showing the highest level of conformity at all dose levels. VMAT resulted in significant reduction of rectal and bladder volumes irradiated at all dose levels compared with 3D-CRT. No significant differences were found with respect to IMRT. Moreover, a significant improvement of the dose conformity was reached by VMAT technique not only at the 95% dose level (0.74 vs. 0.67 and 0.62) but also at 50% and 75% levels of dose prescription. In addition, VMAT plans showed a significant reduction of monitor units by nearly 28% with respect to IMRT, and reduced treatment time from 11 to <3 minutes for a single 6-Gy fraction. In conclusion, VMAT plans can be planned and carried out with high quality and efficiency for the irradiation of vaginal vault alone, providing similar or better sparing of organs at risk to fixed-field IMRT and resulting in the most efficient treatment option. VMAT is currently our standard approach for radiotherapy of low-risk endometrial cancer.

    Objective: longitudinal study with B-mode ultrasonography and Doppler ultrasonography of maternal kidneys and liver in low-risk pregnancy, to establish and quantify normality parameters, correlating them with physiological changes. Materials and methods: twenty-five pregnant women were assessed and selected to participate in the study, each of them undergoing four examinations at the first, second, third trimesters and postpartum. Results: findings during pregnancy were the following: increased renal volume, pyelocaliceal dilatation with incidence of 45.4% in the right kidney, and 9% in the left kidney; nephrolithiasis, 18.1% in the right kidney, 13.6% in the left kidney. With pyelocaliceal dilatation, mean values for resistivity index were: 0.68 for renal arteries; 0.66 for segmental arteries; 0.64 for interlobar arteries; 0.64 for arcuate arteries. Without pyelocaliceal dilatation, 0.67 for renal arteries; 0.64 for segmental arteries; 0.63 for interlobar arteries; and 0.61 for arcuate arteries. Portal vein flow velocities presented higher values in pregnancy, with mean value for maximum velocity of 28.9 cm/s, and 22.6 cm/s postpartum. The waveform pattern of the right hepatic vein presented changes persisting in the postpartum period in 31.8% of the patients. Cholelithiasis was observed in 18.1% of the patients. Conclusion: alterations in renal volume, pyelocaliceal dilatation, nephrolithiasis, cholelithiasis, changes in portal vein flow velocity, alterations in waveform pattern of the right hepatic vein, proved to be significant.

    Is Trichomonas vaginalis (TV) an inducing factor for the development of (pre-)cancerous lesions of the cervix? Cross sectional study. Screening healthy Belgian women with low infection risk. 63,251 consecutive liquid based cervical samples. Real time quantitative PCR for presence of TV, 18 HPV types and Pap smear analysis of cytologic abnormalities. Association of TV and HPV with cervix dysplasia. The overall prevalence of TV DNA was 0.37%, of low risk HPV 2%, of high risk HPV 13.2%, and 8.8 % had cytological abnormalities. Both LR-HPV and HR-HPV were significantly associated with all cytological abnormalities. Presence of TV was associated with LR- and HR-HPV, ASC-US and HSIL, but not with other abnormalities. All women with TV and HSIL also had HR-HPV, while the latter was present in only 59% of women with TV and ASC-US. Amongst HPV negative women, TV was found in 1.3% of women with ASC-US, but only in 0.03% of women with normal cytology (OR 4.2, CL95% 2.1-8.6). In HR-HPV positive women, presence of TV increased the likelihood of cytological abnormalities somewhat (P=0.05), mainly due to an increase in ASC-US and LSIL, but not HSIL. We conclude that TV infection is associated with both LR and HR-HPV infection of the cervix, as well as with ASC-US and HSIL. TV is a concomitant STI, but is not thought to be a co-factor in the causation of HSIL and cervical cancer. However, TV may cause false positive diagnoses of ASC-US.

    This study evaluated the use of statin therapy in U.S. Air Force (USAF) aviators with isolated hypercholesterolemia in terms of compliance with clinical practice guidelines (CPGs) and effectiveness in reducing low-density lipoprotein cholesterol (LDL-C) and coronary heart disease (CHD) risk. This was a mixed design, 8-yr retrospective study that included 8185 participants with isolated hypercholesterolemia, of which 1458 (17.81%) were prescribed statin monotherapy. Overall agreement between CPG recommendations and patient-clinician decision makers was 0.920 (95% confidence interval: 0.955, 0.959) and 0.891 (95% confidence interval: 0.843, 0.851) per 2002 and 2013 CPGs, respectively. Overall agreement was primarily driven by the negative proportion of specific agreement; positive agreement was moderate for the 2002 CPG and poor for the 2013 CPG. LDL-C levels marginally decreased for all participants except non-CPG-recommended statin users per the 2002 CPG. CHD risk was minimally reduced for all participants per the 2002 CPG with the exception of CPG-recommended statin users, for whom risk increased; CHD risk decreased for CPG-recommended statin users, but increased for non-CPG-recommended statin users per the 2013 CPG. No one statin medication was found to be more clinically effective in reducing LDL-C or CHD risk, regardless of dose intensity. Aerospace medicine practitioners are following CPG recommendations for statin therapy. Statins provided minimal benefit, however, and CPG recommendations proved irrelevant in reducing LDL-C and CHD risk in this population of Air Force aviators. This result is attributable, in part, to the young age of the study cohort and the short follow-up period.Tvaryanas AP, Mahaney HJ, Schroeder VM, Maupin GM.

    Pancreatic cancer is the most lethal cancer with an overall 5-year survival rate of 7%1 due to the late stage at diagnosis and the ineffectiveness of current therapeutic strategies. Given the poor prognosis, early detection at a pre-cancerous stage is the best tool for preventing this disease. Intraductal papillary mucinous neoplasms (IPMN), cystic tumors of the pancreas, represent the only radiographically identifiable precursor lesion of pancreatic cancer and are known to evolve stepwise from low-to-high-grade dysplasia before progressing into an invasive carcinoma. Observation is usually recommended for low-risk (low- and intermediate-grade dysplasia) patients, while high-risk (high-grade dysplasia and invasive carcinoma) patients undergo resection; hence, patient selection is critically important in the management of pancreatic cysts.2 Radiologists use standard criteria such as main pancreatic duct size, cyst size, or presence of a solid enhancing component in the cyst to optimally select patients for surgery.3 However, these findings are subject to a radiologist's interpretation and have been shown to be inconsistent with regards to the presence of a mural nodule or solid component.4 We propose objective classification of risk groups based on quantitative imaging features extracted from CT scans. We apply new features that represent the solid component (i.e. areas of high intensity) within the cyst and extract standard texture features. An adaptive boost classifier5 achieves the best performance with area under receiver operating characteristic curve (AUC) of 0.73 and accuracy of 77.3% for texture features. The random forest classifier achieves the best performance with AUC of 0.71 and accuracy of 70.8% with the solid component features.

    Two large, randomized trials are underway evaluating transcatheter aortic valve replacement (AVR) against conventional surgical AVR. We analyzed contemporary, real-world outcomes of surgical AVR in low-risk patients to provide a practical benchmark of outcomes and cost for evaluating current and future transapical AVR technology. From 2010 to 2015, 2,505 isolated AVR operations were performed for severe aortic stenosis at 18 statewide cardiac institutions. Of these, 2,138 patients had a Society of Thoracic Surgeons predicted risk of mortality of less than 4%, and 1,119 met other clinical and hemodynamic criteria as outlined in the PARTNER 3 (The Placement of Transcatheter Aortic Valves) protocol. Patients with endocarditis, end-stage renal disease, ejection fraction of less than 0.45, bicuspid valves, and previous valve replacements were excluded. Outcomes of interest included operative death and postoperative adverse events. The median Society of Thoracic Surgeons predicted risk of mortality for the study-eligible patients was 1.44%, with a median age of 72 years (interquartile range [IQR], 65 to 78 years). Operative mortality was 1.3%, permanent stroke was 1.3%, and pacemaker requirement was 4.2%. The most common adverse events were transfusion of 2 or more units of red blood cells (18%) and atrial fibrillation (28%). The median length of stay was 6 days (IQR, 5 to 8 days). Median total hospital cost was $37,999 (IQR, $30,671 to $46,138). Examination of complications by age younger than 65 vs 65 or older demonstrated a significantly lower need for transfusion (11.2%, p risk patients undergoing surgical AVR in the current era have excellent results. The most common complications were atrial fibrillation and bleeding. These real-world results should provide additional context for upcoming transcatheter clinical trial data.

    To study the relationship between first-trimester uterine artery (UtA) Doppler velocimetry and birth weight in an unselected, low-risk obstetric population. This is a prospective study of 415 low-risk pregnant women who underwent a first-trimester ultrasound evaluation between 11 and 13 weeks of gestation. Blood flow velocimetry waveforms from both UtAs were obtained and the pulsatility index (PI) measured and recorded. Clinical records were reviewed for pregnancy outcomes. Birth weight was expressed as z-scores, and the Spearman correlation coefficient (ρ) was used to calculate the relationship between the mean, delta, and lowest UtA PI values and birth weight. There was no correlation between the mean and delta UtA PI values and birth weight. However, a significant correlation between the lowest UtA PI value and birth weight (ρ = -0.121; p = 0.013) was noted. Our study found a clinically significant correlation between the lowest UtA PI value and birth weight in an unselected, low-risk pregnant population. Because fetal growth is a multifactorial process in which placentation is only one of the factors involved, the use of a single parameter such as Doppler velocimetry remote from the delivery to predict birth weight in a low-risk population seems to be less useful than in the high-risk population. © 2012 John Wiley & Sons, Ltd.

    Telemetry monitoring in patients with low-risk chest pain is highly utilized, despite the lack of quality data to support its use. To review the medical literature on the utility of telemetry monitoring in patients with low-risk chest pain and to offer evidence-based recommendations to emergency physicians. A PubMed literature search was performed and limited to human studies written in English language articles with keywords of "telemetry" and "chest pain." Studies identified then underwent a structured review from which results could be evaluated. There were 114 paper abstracts on telemetry monitoring screened; 30 articles were considered relevant. Twelve appropriate articles were rigorously reviewed and recommendations given. Insufficient data exist to support telemetry use in low-risk chest pain patients. Telemetry monitoring is unlikely to benefit low-risk chest pain patients with a normal/nondiagnostic electrocardiogram, a normal first set of cardiac enzymes, and none of the following: hypotension, rales above the bases, or pain worse than baseline angina.

    2015-05-01

    Induction for postdates in low-risk pregnancy was adopted with the intent to prevent post-term antepartum stillbirth, the most common cause of perinatal death, based on evidence derived in English language RCT meta-analysis. Systematic English language meta-analysis of RCT studies of induction for postdates in low-risk pregnancy report perinatal mortality rates (PMRs) for low-risk pregnancy ranging from 2.6 to 7.6/1000, based on 2-5 stillbirths among 13-16 perinatal deaths, including diabetic pregnancies as well as other high-risk pregnancies irrelevant to the study question. Baseline PMR≥41 weeks in large international databases for high and low risk pregnancies before routine induction 1998-2003 range from 0.9 to 2.4/1000 or about 300% lower than the reported PMR rates for postdate pregnancies in the expectant management arm in English language RCT meta-analysis. Deaths in the first week far exceed stillbirths in the RCT meta-analysis, the opposite of what is expected. These 2 implausible results bring into question the evidence used to justify induction for postdates≥41 weeks. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    This study describes the prevalence and correlates of alcohol use among college students in Ernakulam, Kerala State, India. A total of 5784 students from 58 colleges selected by stratified random sampling completed a questionnaire incorporating standardized instruments. The prevalence of lifetime alcohol use was 21.4% with a male predominance. Among users, low-risk, hazardous, and dependent use were 80.2%, 18.3% and 0.9% respectively. Initiation was mostly with friends (45.3%). Both low-risk and high-risk alcohol users (hazardous and dependent users), in comparison to abstainers, had higher odds of being older, non-Muslim, having a part-time job, using other substances, and exposure to sexual abuse. Students who reported low-risk use also had an urban background, more severe psychological distress and suicidal thoughts, while high-risk users had attention deficit hyperactivity disorder (ADHD) symptoms. Students who reported high-risk use compared to low-risk users had higher odds of having a part-time job, tobacco use, and ADHD symptoms. Alcohol use among college students is common, with both low- and high-risk drinking associated with significant morbidity. This study highlights the need to promote public health policies to target and prevent all patterns of alcohol use among young people.

    No studies have identified which patients with upper-extremity deep vein thrombosis (DVT) are at low risk for adverse events within the first week of therapy. We used data from Registro Informatizado de la Enfermedad TromboEmbólica to explore in patients with upper-extremity DVT a prognostic score that correctly identified patients with lower limb DVT at low risk for pulmonary embolism, major bleeding, or death within the first week. As of December 2014, 1135 outpatients with upper-extremity DVT were recruited. Of these, 515 (45%) were treated at home. During the first week, three patients (0.26%) experienced pulmonary embolism, two (0.18%) had major bleeding, and four (0.35%) died. We assigned 1 point to patients with chronic heart failure, creatinine clearance levels 30-60 mL min(-1) , recent bleeding, abnormal platelet count, recent immobility, or cancer without metastases; 2 points to those with metastatic cancer; and 3 points to those with creatinine clearance levels low risk. The rate of the composite outcome within the first week was 0.26% (95% confidence interval [CI] 0.004-0.87) in patients at low risk and 1.86% (95% CI 0.81-3.68) in the remaining patients. C-statistics was 0.73 (95% CI 0.57-0.88). Net reclassification improvement was 22%, and integrated discrimination improvement was 0.0055. Using six easily available variables, we identified outpatients with upper-extremity DVT at low risk for adverse events within the first week. These data may help to safely treat more patients at home. © 2015 International Society on Thrombosis and Haemostasis.

    Studies investigating the relation between risk profiles and cardiovascular disease have measured risk at baseline only. We investigated maintenance and changes of risk profiles over time and their potential impact on incident cardiovascular disease. Population-based cohort study. Risk factors were measured at baseline (1987-1991) among 5574 cardiovascular disease-free adults aged 20-59 years. They were classified into four risk categories according to smoking status, presence of diabetes and widely accepted cut-off values for blood pressure, total cholesterol/HDL-ratio and body mass index. Categories were subdivided (maintenance, deterioration, improvement) based on risk factor levels at six and 11 years of follow-up. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for cardiovascular disease incidence 5-10 years following the risk-change period were fitted using Cox proportional hazards models. Only 12% of participants were low risk at baseline, and only 7% maintained it. Participants who maintained a low risk profile over 11 years had seven times lower risk of cardiovascular disease (HR: 0.14, 95% CI: 0.05-0.41) than participants with long-term high risk profile, whereas those low risk at baseline whose profile deteriorated had three times lower risk (HR: 0.36, 95% CI: 0.18-0.71). Our results suggest that, within each baseline risk profile group, compared with a stable profile, improving profiles may be associated with up to two-fold lower HRs, and deteriorating profiles with about two-fold higher HRs. Our study, using long-term risk profiles, demonstrates the full benefits of low risk profile. These findings underscore the importance of achieving and maintaining low risk from young adulthood onwards. © The European Society of Cardiology 2014.

    Purpose: To identify clinical and pathological factors that identify groups of women with stage I breast cancer with a 5-year risk of local recurrence (LR) ≤1.5% after breast-conserving therapy (BCS) plus whole-breast radiation therapy (RT). Methods and Materials: Study subjects were 5974 patients ≥50 years of age whose cancer was diagnosed between 1989 and 2006, and were referred with pT1 pN0 invasive breast cancer treated with BCS and RT. Cases of 5- and 10-year LR were examined using Kaplan-Meier methods. Recursive partitioning analysis was performed in patients treated with and without endocrine therapy to identify combinations of factors associated with a 5-year LR risk ≤1.5%. Results: The median follow-up was 8.61 years. Median age was 63 years of age (range, 50 to 91). Overall 5-year LR was 1.5% (95% confidence interval [CI], 1.2%-1.9%) and 10-year LR was 3.4% (95% CI, 2.8%-4.0%). Of 2830 patients treated with endocrine therapy, patient subsets identified with 5-year LR ≤1.5% included patients with grade 1 histology (n=1038; LR, 0.2%; 95% CI, 0%-0.5%) or grade 2 histology plus ≥60 years of age (n=843; LR, 0.5%; 95% CI, 0%-1.0%). Ten-year LR for these groups were 0.8% (95% CI, 0.1%-1.6%) and 0.9% (95% CI, 0.2%-1.6%), respectively. Of 3144 patients treated without endocrine therapy, patients with grade 1 histology plus clear margins had 5-year LR ≤1.5% (n=821; LR, 0.6%; 95% CI, 0.1%-1.2%). Ten-year LR for this group was 2.2% (95% CI, 1.0%-3.4%). Conclusions: Histologic grade, age, margin status, and use of endocrine therapy identified 45% of a population-based cohort of female patients over age 50 with stage I breast cancer with a 5-year LR risk ≤1.5% after BCS plus RT. Prospective study is needed to evaluate the safety of omitting RT in patients with such a low risk of LR.

    Introduction Internationally, there is debate on the safety of different birth settings inside and outside of hospitals. Low-risk women in Germany can choose where they give birth, and out-of-hospital births are especially necessary in regions lacking infrastructure. To date, national studies are required. Materials and Methods We investigated planned out-of-hospital (OH) and hospital births in Lower Saxony, Germany, in 2005. Women with a singleton fetus in the vertex position were included once they reached 34+0 gestational weeks. 1 273 out of 4 424 births were included via risk assessment. Outcomes were compared using Pearson's chi-squared test, the Mann-Whitney test, and logistic regression. Results 152 (36.6%) nulliparae (NP) and 263 (63.4%) multiparae (MP) gave birth out of hospital, 439 (51.2%) nulliparae and 419 (48.8%) multiparae in a hospital. 10.1% of women whose care started outside of the hospital needed a transfer to the hospital. Women who planned OH were older and had a higher level of education. Women without a migration background displayed an increased rate of out-of-hospital birth. A higher proportion received their antenatal care from midwives rather than medical doctors. Induction of labor was less likely for women with planned out-of-hospital births, as were other intrapartum interventions. In hospital births, fetal monitoring was more likely performed via cardiotocograph instead of intermittent auscultation. Duration of labor was significantly longer in OH births (median: NP: 9.01 h vs. 7.38 h; MP: 4.53 h vs. 4.25 h). Nulliparae had more spontaneous births out-of-hospital (94.7%) than in hospital (73.6%). There was no difference in adverse fetal outcomes, blood loss, and severe perineal lacerations. The perineum was less frequently intact in hospital births. Retained placenta was more often documented in out-of-hospital births. Conclusions In an out-of-hospital setting, fewer interventions were performed, spontaneous births

    Fear of childbirth is a common reason for seeking cesarean section. It is important to consider outcomes and costs associated with alternative treatment and delivery mode. We compared well-being and costs of group psychoeducation and conventional care for fear of childbirth. Randomized controlled trial. A total of 371 nulliparous women scoring over the 95th centile in the Wijma Delivery Expectancy Questionnaire (W-DEQ) during the first trimester. Finland, data from obstetrical patient records and questionnaires. Randomization to group psychoeducation with relaxation (six sessions during pregnancy, one after childbirth, n = 131), or surveillance and referral on demand (n = 240). All costs in maternity care during pregnancy, delivery and postnatally according to Diagnoses Related Groups. Life satisfaction and general well-being 3 months after childbirth (by a Satisfaction with Life Scale and Well-being Visual Analogue Scale). The groups did not differ in total direct costs (€3786/woman in psychoeducative group and €3830/woman in control group), nor in life satisfaction or general well-being. Although only 76 (30%) of the women assigned to the surveillance were referred to special maternity care and 36 (15%) attended advanced prenatal classes, costs in the psychoeducation group did not exceed the costs of the controls, mostly because of the greater number of uncomplicated vaginal deliveries (63% vs. 47%, p = 0.005). Through an association with safer childbirth and equal well-being after delivery, psychoeducative group treatment for nulliparous women with fear of childbirth can be a recommended choice for the same overall costs as conventional treatment. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Plasminogen activator inhibitor type 1 (PAI-1) is an important regulator of fibrinolysis. A common deletion polymorphism that results in a sequence of 4G instead of 5G in the promoter region of the gene is associated with a small increase in the risk of venous thromboembolism. Its potential association with adverse pregnancy events remains controversial. We aimed to assess the impact of the 4G PAI-1 polymorphism on pregnancy outcomes in women who had no prior history of adverse pregnancy outcomes or personal or family history of venous thromboembolism. This study represents a secondary investigation of a prior prospective cohort study investigating the association between inherited thrombophilias and adverse pregnancy events in Australian women. Healthy nulliparous women were recruited to this study prior to 22 weeks gestation. Genotyping for the 4G/5G PAI-1 gene was performed using Taqman assays in an ABI prism 7700 Sequencer several years after the pregnancy was completed. Pregnancy outcome data were extracted from the medical record. The primary outcome was a composite comprising development of severe pre-eclampsia, fetal growth restriction, major placental abruption, stillbirth or neonatal death. Pregnancy outcome data were available in 1733 women who were successfully genotyped for this polymorphism. The primary composite outcome was experienced by 139 women (8% of the cohort). Four hundred and fifty-nine women (26.5%) were homozygous for the 4G deletion polymorphism, while 890 (51.4%) were heterozygous. Neither homozygosity nor heterozygosity for the PAI-1 4G polymorphism was associated with the primary composite outcome (homozygous OR = 1.30, 95% CI = 0.81-2.09, P = 0.28, heterozygous OR = 0.84, 95% CI = 0.53-1.31, P = 0.44) or with the individual pregnancy complications.

    To determine the effect of perineal lacerations on pelvic floor outcomes, including urinary and anal incontinence, sexual function, and perineal pain in a nulliparous cohort with low incidence of episiotomy. Nulliparous women were prospectively recruited from a midwifery practice. Pelvic floor symptoms were assessed with validated questionnaires, physical examination, and objective measures in pregnancy and 6 months postpartum. Two trauma groups were compared, those with an intact perineum or only 1st degree lacerations and those with second-, third-, or fourth-degree lacerations. Four hundred and forty-eight women had vaginal deliveries. One hundred and fifty-one sustained second-degree or deeper perineal trauma and 297 had an intact perineum or minor trauma. Three hundred and thirty-six (74.8%) presented for 6-month follow-up. Perineal trauma was not associated with urinary or fecal incontinence, decreased sexual activity, perineal pain, or pelvic organ prolapse. Women with trauma had similar rates of sexual activity; however, they had slightly lower sexual function scores (27.3 vs 29.1). Objective measures of pelvic floor strength, rectal tone, urinary incontinence, and perineal anatomy were equivalent. The subgroup of women with deeper (> 2 centimeter) perineal trauma demonstrated increased likelihood of perineal pain (15.5% vs 6.2%) and weaker pelvic floor muscle strength (61.0% vs 44.3%) compared with women with more superficial trauma. Women having second-degree lacerations are not at increased risk for pelvic floor dysfunction other than increased pain, and slightly lower sexual function scores at 6 months postpartum. © 2016 Wiley Periodicals, Inc.

    Inclusive in the planning of Spaceport Malaysia are 2 local suborbital vehicles development. One of the vehicles is called SOLVES or Suborbital Low Cost and Low Risk Vehicle to the Edge of Space. The emphasis on the design and operation of SOLVES is green and robotic technology, where both green technology and robotic technology are used to protect the environment and enhance safety. As SOLVES climbs, its center of gravity stabilizes and remains at the bottom as its propellant being used until it depletes, due to the position of the vehicle's passenger cabin and its engines at its lower end. It will reach 80km from sea level generally known as "the edge of space" due to its momentum although its propellant will be depleted at a lower altitude. As the suborbital vehicle descends tail first, its wings automatically extend and rotate at horizontal axes perpendicular to the fuselage. These naturally and passively rotating wings ensure controlled low velocity and stable descend of the vehicle. The passenger cabin also rotates automatically at a steady low speed at the centerline of its fuselage as it descends, caused naturally by the lift force, enabling its passengers a surrounding 360 degrees view. SOLVES is steered automatically to its landing point by an electrical propulsion system with a vectoring nozzle. The electrical propulsion minimizes space and weight and is free of pollution and noise. Its electrical power comes from a battery aided by power generated by the naturally rotating wings. When the vehicle lands, it is in the safest mode as its propellant is depleted and its center of gravity remains at the bottom of its cabin. The cabin, being located at the bottom of the fuselage, enables very convenient, rapid and safe entry and exit of its passengers. SOLVES will be a robotic suborbital vehicle with green technology. The vehicle will carry 4 passengers and each passenger will be trained to land the vehicle manually if the fully automated landing system fails

    South Africa's health system is based on the primary care model in which low-risk maternity care is provided at community health centres and clinics, and 'high-risk' care is provided at secondary/tertiary hospitals. This model has the disadvantage of delays in the management of unexpected intrapartum complications in otherwise low-risk pregnancies, therefore, there is a need to re-evaluate the models of birth care in South Africa. To date, two primary care onsite midwife-led birth units (OMBUs) have been established in the Eastern Cape. OMBUs are similar to alongside midwifery units but have been adapted to the South African health system in that they are staffed, administered and funded by the primary care service. They allow women considered to be at 'low risk' to choose between birth in a community health centre and birth in the OMBU. The purpose of this audit was to evaluate the impact of establishing an OMBU at Frere Maternity Hospital in East London, South Africa, on maternity services. We conducted an audit of routinely collected data from Frere Maternity Hospital over two 12 month periods, before and after the OMBU opened. Retrospectively retrieved data included the number of births, maternal and perinatal deaths, and mode of delivery. After the OMBU opened at Frere Maternity Hospital, the total number of births on the hospital premises increased by 16%. The total number of births in the hospital obstetric unit (OU) dropped by 9.3%, with 1611 births out of 7375 (22%) occurring in the new OMBU. The number of maternal and perinatal deaths was lower in the post-OMBU period compared with the pre-OMBU period. These improvements cannot be assumed to be the result of the intervention as observational studies are prone to bias. The mortality data should be interpreted with caution as other factors such as change in risk profile may have contributed to the death reductions. There are many additional advantages for women, hospital staff and primary care staff with

    No prior studies have identified which patients with deep vein thrombosis in the lower limbs are at a low risk for adverse events within the first week of therapy. We used data from the Registro Informatizado de la Enfermedad TromboEmbólica (RIETE) to identify patients at low risk for the composite outcome of pulmonary embolism, major bleeding, or death within the first week. We built a prognostic score and compared it with the decision to treat patients at home. As of December 2013, 15,280 outpatients with deep vein thrombosis had been enrolled. Overall, 5164 patients (34%) were treated at home. Of these, 12 (0.23%) had pulmonary embolism, 8 (0.15%) bled, and 4 (0.08%) died. On multivariable analysis, chronic heart failure, recent immobility, recent bleeding, cancer, renal insufficiency, and abnormal platelet count independently predicted the risk for the composite outcome. Among 11,430 patients (75%) considered to be at low risk, 15 (0.13%) suffered pulmonary embolism, 22 (0.19%) bled, and 8 (0.07%) died. The C-statistic was 0.61 (95% confidence interval [CI], 0.57-0.65) for the decision to treat patients at home and 0.76 (95% CI, 0.72-0.79) for the score (P = .003). Net reclassification improvement was 41% (P deep vein thrombosis at low risk for adverse events within the first week. These data may help to safely treat more patients at home. This score, however, should be validated. Copyright © 2015 Elsevier Inc. All rights reserved.

    Routine preoperative pulmonary function tests (PFTs) are not recommended prior to low-risk surgery because their prognostic value is limited. However, only a few studies have assessed the utilization of healthcare resources regarding preoperative PFTs in a real-world setting. Here, we aimed to assess the prevalence and determinant factors of preoperative PFTs before low-risk surgery in Japan. In this retrospective cohort study, we used the nationwide insurance claims databases. Patients who underwent low-risk surgeries under general anesthesia between April 1, 2012, and March 31, 2016, were included. The primary outcome was the receipt of PFTs within 60 days before an index surgery. We performed descriptive analyses to estimate the rates of preoperative PFTs annually starting in 2012, and examined the associations between patient- and institutional-level factors and preoperative PFTs using multilevel logistic regression analyses. The cohort included 9495 procedures (8866 patients) at 1487 institutions. Preoperative PFTs were conducted before 71.8% of the procedures. The temporal trend of preoperative PFTs remained constant from 72.4% in 2012 to 72.2% in 2015. Multilevel regression analysis revealed that preoperative PFTs were associated with older age, number of beds at a medical facility, and inpatient procedures. The median institutional-specific proportion of PFTs was 75.0% (interquartile range, 14.3-100%) with wide inter-institutional variation. Our analysis found that preoperative PFTs were performed before 72% of low-risk surgeries under general anesthesia. Apart from age, preoperative PFTs were determined primarily by non-medical factors. Additionally, we observed substantial institutional variation in the use of preoperative PFTs.

    To compare radiation related toxicities among men with low risk prostate cancer treated with single or multimodal radiation therapy. The SEER-Medicare linked database was used to assess the relationship between treatment type and toxicity among men with low risk prostate cancer treated with brachytherapy (BT), external beam radiation therapy (EBRT), or combined therapy between 2004 and 2007. Inverse probability of treatment weighting was utilized to minimize selection bias and control for confounding. Multivariate logistic regression models were used to explore the relationship between treatment and outcomes. Overall 1915 (43.9%), 1893 (43.4%), and 555 (12.7%) patients were treated with EBRT, BT, and combined therapy, respectively. In univariate analyses, combined modality radiation was more toxic than BT alone for GU incontinence (56.76% versus 49.08%), GU obstruction (21.26% versus 19.70%), and erectile dysfunction (22.52% versus 22.24%) (p combined modality radiation was more toxic for GI bleeding (7.21% versus 6.21%), GU incontinence (56.76% versus 29.24%), GU obstruction (21.26% versus 14.15%), and erectile dysfunction (22.52% versus 15.35%) (p combined modality treatment and lowest for the group treated with EBRT. After multivariate adjustment, EBRT alone demonstrated protective effects against GU obstruction (OR 0.56 [CI 0.50-0.63]), GI bleeding (OR 0.57 [CI 0.48-0.67]), GU incontinence (OR 0.39 [CI 0.36-0.43]), and erectile dysfunction (OR 0.68 [CI 0.61-0.76]) when compared to combined therapy. The use of combined modality radiation therapy in low risk prostate cancer patients is discordant with clinical guidelines and associated with a significantly increased burden of associated toxicity when compared to EBRT monotherapy. Prudent patient selection and judicious use of combined therapy among men with low risk prostate cancer represents a targetable area to reduce the burden of overtreatment.

    OBJECTIVE: To determine the absolute risk of cervical intraepithelial neoplasia (CIN) grade 3 or cervical cancer (CIN 3 or worse) after detection of low-risk human papillomavirus (HPV) and after a negative high-risk HPV test. METHODS: In this prospective cohort study, consecutive liquid......-based cervical cytology samples were collected from women screened for cervical cancer in Copenhagen, Denmark, during 2002-2005. Samples were tested with a clinical test for 13 high-risk and five low-risk HPV types. The cohort (N=35,539; aged 14-90 years) was monitored in a nationwide pathology register for up...... to 10.5 years for development of CIN 3 or worse. RESULTS: The 8-year absolute risk of CIN 3 or worse was 1.1% (95% confidence interval [CI] 1.0-1.3%) for HPV-negative women; 1.7% (0.8-2.6%) for low-risk HPV-positive women without concurrent high-risk HPV; 17.4% (16.4-18.5%) for high-risk HPV...

    Although new agents have been approved for the treatment of MDS, the only curative approach is allogeneic hematopoietic stem cell transplantation (HSCT) and thus, in particular circumstances this procedure has been proposed as a treatment option for low risk patients. We have retrospectively analyzed the results of HSCT in 291 patients from the Spanish MDS registry with special attention to low risk MDS (LR-MDS) in order to define the variables that could impact their clinical evolution after transplantation. At 2 years OS was 51% and EFS was 50% (95% CI 0.7-4.5 years for OS and 95% CI 0.1-3.9 years for EFS). Among 43 LR-MDS, transplant-related mortality was 28%. At 3 years, OS was 67% (95% CI 264.7-8927.2 days for OS) and EFS was 64% (95% CI 0-9697.2 days for EFS). In the multivariate analysis only cytogenetics retained statistical significant effect on both OS (p=.047) and EFS (p=.046). Conditioning regimen could improve outcome among this subset of patients (OS 86% and RFS 100% for patients receiving RIC regimen). The present study confirms that specific disease characteristic as well as transplant characteristics have a significant impact on transplant outcome. Regarding low risk patients a non-myeloablative conditioning would be preferable especially in cases without high-risk cytogenetics. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The purpose of this study was to evaluate the risk of adverse maternal outcomes associated with trial of labor (TOL) after cesarean during subsequent pregnancies in the low-risk population. We conducted a retrospective cohort study using the Nationwide Inpatient Sample and ICD-9 diagnostic and procedure codes from the years 2003 to 2011. A cohort of low-risk pregnant women with a history of previous cesarean delivery were identified and separated into two groups: TOL and no TOL. Logistic regression analysis was used to calculate odds ratios (ORs) comparing adverse maternal outcomes between these two groups. Out of 7 290 474 registered deliveries, there were 685 137 low-risk women who met inclusion criteria. Of these women, 144 066 (21.0%) underwent a TOL, with rates remaining steady over the course of our study. The TOL group was at increased risk of overall morbidity (OR 1.74, 95% confidence interval (CI), 1.66-1.79), most notably uterine rupture (OR 22.52, 95% CI, 19.35-26.20, Pcesarean delivery.

    To investigate rates of caesarean delivery in Sweden and Norway from 1973 to 2008 in relation to advanced and very advanced maternal age. Register study. Sweden and Norway. All nulliparous women aged over 30 years with a singleton pregnancy, with the fetus in a cephalic presentation, and delivering at term between 1973 and 2008 were evaluated. The study population comprised 329 824 women in Sweden and 127 810 women in Norway. Data from the national Medical Birth Registers were used to describe caesarean section rates in three age groups: 30-34 years (reference group); 35-39 years (advanced age group); and ≥ 40 years (very advanced age group). Logistic regression analyses estimated the risk in each age group over four decades, in each of the two national samples. Caesarean delivery decreased from 1973-1979 to 2000-2008 in the two oldest age groups in Sweden (35-39 years, OR = 0.53, 95% CI = 0.50-0.58; ≥ 40 years, OR = 0.36, 95% CI = 0.30-0.43) and Norway (35-39 years, OR = 0.61, 95% CI = 0.54-0.68; ≥ 40 years, OR = 0.45, 95% CI = 0.34-0.58), but increased in women aged 30-34 years. The caesarean delivery rate in the two oldest groups peaked in the second half of the 1970s. Regardless of time point, the caesarean delivery rate was always highest in women aged ≥ 40 years, followed by women aged 35-39 years and lowest in women aged 30-34 years. Caesarean delivery in nulliparous women of advanced and very advanced age peaked by end of the 1970s in Sweden and Norway. The subsequent reduction was contemporaneous with the introduction of electronic fetal monitoring and a more consistent use of the partogram, suggesting that more effective surveillance of labour increased the chance of a vaginal birth in these high-risk women. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

  2. Induction of labour versus expectant management for nulliparous women over 35 years of age: a multi-centre prospective, randomised controlled trial

    Full Text Available Abstract Background British women are increasingly delaying childbirth. The proportion giving birth over the age of 35 rose from 12% in 1996 to 20% in 2006. Women over this age are at a higher risk of perinatal death, and antepartum stillbirth accounts for 61% of all such deaths. Women over 40 years old have a similar stillbirth risk at 39 weeks as women who are between 25 and 29 years old have at 41 weeks. Many obstetricians respond to this by suggesting labour induction at term to forestall some of the risk. In a national survey of obstetricians 37% already induce women aged 40–44 years. A substantial minority of parents support such a policy, but others do not on the grounds that it might increase the risk of Caesarean section. However trials of induction in other high-risk scenarios have not shown any increase in Caesarean sections, rather the reverse. If induction for women over 35 did not increase Caesareans, or even reduced them, it would plausibly improve perinatal outcome and be an acceptable intervention. We therefore plan to perform a trial to test the effect of such an induction policy on Caesarean section rates. This trial is funded by the NHS Research for Patient Benefit (RfPB Programme. Design The 35/39 trial is a multi-centre, prospective, randomised controlled trial. It is being run in twenty UK centres and we aim to recruit 630 nulliparous women (315 per group aged over 35 years of age, over two years. Women will be randomly allocated to one of two groups: Induction of labour between 390/7 and 396/7 weeks gestation. Expectant management i.e. awaiting spontaneous onset of labour unless a situation develops necessitating either induction of labour or Caesarean Section. The primary purpose of this trial is to establish what effect a policy of induction of labour at 39 weeks for nulliparous women of advanced maternal age has on the rate of Caesarean section deliveries. The secondary aim is to act as a pilot study for a trial to

    In 2009 the Institute of Medicine updated its guidelines for weight gain during pregnancy, in part because women of childbearing age now weigh more pre-pregnancy and tend to gain more weight during pregnancy than women did when the previous set of guidelines were released in 1990. Women who begin pregnancy overweight or obese and women who gain weight outside IOM recommendations are at risk for poor maternal and fetal health outcomes. With these concerns in mind, we examined what obstetricians communicate about gestational weight gain to their pregnant patients and how nulliparous patients perceive weight-related counseling from their obstetricians. We conducted one-on-one, semi-structured interviews with 19 nulliparous women and 7 obstetricians recruited from a single clinic at a large academic medical center in the United States. Interviews were transcribed verbatim and analyzed inductively using thematic analysis. We identified 4 major themes: 1) Discussions about the amount and pace of gestational weight gain: obstetricians reported variation in the frequency and timing of weight-related discussions with patients while most patients said that weight was not emphasized by their obstetricians; 2) The content of communication about nutrition and physical activity: obstetricians said they discuss nutrition and activity with all patients while most patients reported that their obstetrician either discussed these topics in general terms or not at all; 3) Communication about postpartum weight loss: obstetricians said that they do not typically address postpartum weight loss with patients during prenatal visits while patients had concerns about postpartum weight; and 4) Patient feelings about obstetrician advice: most patients said that their obstetrician does not tend to offer "unsolicited advice", instead offering information in response to patient questions or concerns. Women were divided about whether they desired more advice from their obstetrician on weight gain

    Neutropenic fever (NF) is a common complication of cancer chemotherapy. Patients at low risk of medical complications from NF can be identified using a validated risk assessment and managed in an outpatient setting. This is a new model of care for Australia. This study described the implementation of a sustainable ambulatory program for NF at a tertiary cancer centre over a 12-month period. Peter MacCallum Cancer Centre introduced an ambulatory care program in 2014, which identified low-risk NF patients, promoted early de-escalation to oral antibiotics, and early discharge to a nurse-led ambulatory program. Patients prospectively enrolled in the ambulatory program were compared with a historical-matched cohort of patients from 2011 for analysis. Patient demographics, clinical variables (cancer type, recent chemotherapy, treatment intent, site of presentation) and outcomes were collected and compared. Total cost of inpatient admissions was determined from diagnosis-related group (DRG) codes and applied to both the prospective and historical cohorts to allow comparisons. Twenty-five patients were managed in the first year of this program with a reduction in hospital median length of stay from 4.0 to 1.1 days and admission cost from Australian dollars ($AUD) 8580 to $AUD2360 compared to the historical cohort. Offsetting salary costs, the ambulatory program had a net cost benefit of $AUD 71895. Readmission for fever was infrequent (8.0%), and no deaths were reported. Of relevance to hospitals providing cancer care, feasibility, safety, and cost benefits of an ambulatory program for low-risk NF patients have been demonstrated.

    Human papilloma virus is the causative agent for cervical cancer with 99 % of cervical cancer cases containing HPV. The high risk HPV-16, 18 and 31 are the major causative agents. The low risk HPV-6, 11 have been reported to cause penile, laryngeal, bronchogenic and oesophageal cancer. Since E6 oncoprotein is frequently over expressed in cancers, we did gene expression studies to compare between the E6 genes of high-risk (HPV18) or low-risk (HPV11)stably transfected in epithelial cell line EPC-2 or mock transfected with the basic vector pCDNA3.1. Microarray studies showed a total of 697 genes showing differential expression between the samples. Genes involved in several key cellular processes such as cell adhesion, angiogenesis, transcription regulation, cell cycle regulation and cell division showed altered expression between the samples. Gene Ontology mapping of 44 genes according cellular pathways revealed 13 pathways namely angiogenesis, alzhemier's, Wnt, p53, interleukin, TGF-β, cadherin, integrin, PI3-kinase, catennin, insulin, chemokine and G protein signalling pathways. The microarray results were confirmed by quantitative real-time PCR for some representative genes like IFI27, CTNNA1, OSMR, CYP1B1, TNFSF13, LAMA2 and COL5A3. Analysis of differentially expressed genes by high-risk and low-risk HPV E6 proteins might help in identification of potential biomarkers for diagnosis, progression and therapy of oesophageal cancer. The understanding of mechanisms of activation of these genes as well as the function of gene products will give a further insight into their roles in oesophageal cancer.

    The optimal duration of antibiotic treatment for hematogenous vertebral osteomyelitis (HVO) should be based on the patient's risk of recurrence, but it is not well established. A retrospective review was conducted to evaluate the optimal duration of antibiotic treatment in patients with HVO at low and high risk of recurrence. Patients with at least 1 independent baseline risk factor for recurrence, determined by multivariable analysis, were considered as high risk and those with no risk factor as low risk. A total of 314 patients with microbiologically diagnosed HVO were evaluable for recurrence. In multivariable analysis, methicillin-resistant Staphylococcus aureus infection (adjusted odds ratio [aOR], 2.61; 95% confidence interval [CI], 1.16-5.87), undrained paravertebral/psoas abscesses (aOR, 4.09; 95% CI, 1.82-9.19), and end-stage renal disease (aOR, 6.58; 95% CI, 1.63-26.54) were independent baseline risk factors for recurrence. Therefore, 191 (60.8%) patients were classified as low risk and 123 (39.2%) as high risk. Among high-risk patients, there was a significant decreasing trend for recurrence according to total duration of antibiotic therapy: 34.8% (4-6 weeks [28-41 days]), 29.6% (6-8 weeks [42-55 days]), and 9.6% (≥8 weeks [≥56 days]) (P = .002). For low-risk patients, this association was still significant but the recurrence rates were much lower: 12.0% (4-6 weeks), 6.3% (6-8 weeks), and 2.2% (≥8 weeks) (P = .02). Antibiotic therapy of prolonged duration (≥8 weeks) should be given to patients with HVO at high risk of recurrence. For low-risk patients, a shorter duration (6-8 weeks) of pathogen-directed antibiotic therapy may be sufficient. © The Author 2016.

    During the last decade transcatheter aortic valve replacement (TAVR) has been established as a treatment for patients with severe aortic stenosis, who are at particularly high surgical risk. As compared with surgical aortic valve replacement (SAVR), TAVR has been associated with lower early risk...... is currently being evaluated in prospective randomized trials against SAVR in younger low-risk patients. Although durability of the TAVR device may be of concern in younger patients given their longer life expectancy, intermediate-term controlled data does not reveal any difference between TAVR and SAVR...

  8. Clinical governance and research ethics as barriers to UK low-risk population-based health research?

    Full Text Available Abstract Background Since the Helsinki Declaration was introduced in 1964 as a code of practice for clinical research, it has generally been agreed that research governance is also needed in the field of public health and health promotion research. Recently, a range of factors led to the development of more stringent bureaucratic procedures, governing the conduct of low-risk population-based health research in the United Kingdom. Methods Our paper highlights a case study of the application process to medical research ethics committees in the United Kingdom for a study of the promotion of physical activity by health care providers. The case study presented here is an illustration of the challenges in conducting low-risk population-based health research. Results Our mixed-methods approach involved a questionnaire survey of and semi-structured interviews with health professionals (who were all healthy volunteers. Since our study does not involve the participation of either patients or the general population, one would expect the application to the relevant research ethics committees to be a formality. This proved not to be the case! Conclusion Research ethics committees could be counter-productive, rather than protecting the vulnerable in the research process, they can stifle low-risk population-based health research. Research ethics in health services research is first and foremost the responsibility of the researcher(s, and we need to learn to trust health service researchers again. The burden of current research governance regulation to address the perceived ethical problems is neither appropriate nor adequate. Senior researchers/academics need to educate and train students and junior researchers in the area of research ethics, whilst at the same time reducing pressures on them that lead to unethical research, such as commercial funding, inappropriate government interference and the pressure to publish. We propose that non-invasive low-risk

    Inclusion of high levels of the high-fibre ingredient sugar-beet pulp in pre-mating diets has been shown to increase gonadotrophin concentrations and improve oocyte quality in nulliparous pigs (gilts). This study evaluated the effects of two alternative fibre sources on reproductive performance in gilts. Gilts received one of three diets from 3 weeks before puberty stimulation until Day 19 of the first oestrous cycle: control (39 g kg⁻¹ fibre), bran (500 g kg⁻¹ wheat bran, 65 g kg⁻¹ fibre) or lupin (350 g kg⁻¹ lupin, 118 g kg⁻¹ crude fibre). Diet did not affect circulating LH concentrations or ovarian follicle size. However, a higher percentage of oocytes collected from lupin-supplemented gilts reached metaphase II in vitro compared with those collected from bran-fed or control gilts (89±5% versus 72±5% and 66±5%, respectively; Pgilts fed the same lupin-based diet before mating had improved embryo survival (92±5%) on Day 28 after mating compared with control gilts (76±4%; Pgilts without changes in circulating LH, but this effect is dependent on the fibre source.

    The purpose of this study was to assess the influence of the duration of active second-stage labor on maternal and neonatal outcomes. Secondary analysis of the Pushing Early Or Pushing Late with Epidural trial that included 1862 nulliparous women with epidural analgesia who were in the second stage of labor. According to duration of active second-stage labor, we estimated the proportion of spontaneous vaginal deliveries (SVD) with a newborn infant without signs of asphyxia (5-minute Apgar score > or =7 and arterial pH >7.10). We also analyzed maternal and neonatal outcomes according to the duration of expulsive efforts. Relative to the first hour of expulsive efforts, the chances of a SVD of a newborn infant without signs of asphyxia decreased significantly every hour (1- to 2-hour adjusted odds ratio, 0.4; 95% confidence interval [CI], 0.3-0.6; 2- to 3-hour adjusted odds ratio, 0.1; 95% CI, 0.09-0.2; >3-hour adjusted odds ratio, 0.03; 95% CI, 0.02-0.05). The risk of postpartum hemorrhage and intrapartum fever increased significantly after 2 hours of pushing. Faced with a decreasing probability of SVD and increased maternal risk of morbidity after 2 hours, we raise the question as to whether expulsive efforts should be continued after this time.

    A 51 year-old woman was diagnosed with endometrial cancer (EC) and underwent surgical staging. Pathological evaluation showed a 2 cm × 1 cm G2 endometrioid EC with a 30% myometrial deep invasion (FIGO Stage 1A). The patient was classified as low risk of recurrence, and no adjuvant treatment was offered. Six months after surgery, the patient developed an early vescico-vaginal recurrence, and chemotherapy treatment was started. Few months later, a subsequent involvement of vaginal wall, ileum, and omentum was detected, and the patient underwent second surgery. LH/hCG-receptor (LH/hCG-R) expression has been previously reported to be associated with an invasive phenotype in EC cells. Moreover, in a preclinical mouse model of EC behaves as a prometastatic molecular device. We analyzed the expression level of LH/hCG-R in cancer specimens collected during surgeries. Molecular and immunohistochemical analyses showed a strong expression of both mRNA and protein for LH/hCG-R in all specimens. LH/hCG-R expression may be assessed together with other clinicopathological parameters in order to better predict the risk of recurrence in low-risk EC patients. Further clinical trials are warranted in order to validate LH/hCG-R as biomarker in EC.

    The aim of this paper was to compare the results of postoperative I-131 remnant ablation therapy using a quantitative data in the low activity (1110 MBq) and standard dose (3700 MBq). The study included two groups of patients with low risk differentiated thyroid cancer (DTC): Group L (low dose group) included 54 patients who were treated with 1110 MBq I-131 and Group S (standard dose group) included 61 patients treated with 3700 MBq. The postoperative thyroid remnants were assessed with the pretreatment thyroid uptake test (PTUT) and the whole body scans (WBS) were performed in the 7th day after the ablation treatment. We obtained the average count per pixel from the standard region of interest analysis of the thyroid bed (Tavc), liver (Lavc), thigh (Thavc) and whole body (WBkc). At the sixth month after the treatment, WBS were performed to 106 patients (45 patients from Group L and 61 patients from Group S) to evaluate the success of ablation treatment. A significant difference in PTUT and Tavc was not found between the two groups (P>0.05). However, Lavc, Thavc and WBkc were significantly higher in Group S compared with Group L (P0.05). In low risk DTC patients, low dose radioactive iodine can ablate thyroid remnants as effectively as a higher dose with less radiation exposure to other non-target organs and the whole body.

    To determine the correlation between transabdominal (TA) and transvaginal (TV) cervical length measurement in a low-risk obstetric population in Taiwan. Women with a singleton pregnancy between 20 weeks and 24 weeks of gestation underwent postvoid TA and TV cervical length measurements. Differences between the measurements obtained using the two methods were evaluated. Two hundred and five women agreed to participate in the study. Paired TA and TV measurements were obtained in 174 women. The mean TA cervical length was 36.0 ± 4.9 mm and the mean TV cervical length was 37.6 ± 5.4 mm. The mean TA cervical length was shorter than the mean TV cervical length by 1.6 mm. The 5(th) percentile of TA and TV cervical length was 29 mm and 29.1 mm, respectively. The discrepancies between the two methods were not significantly correlated with maternal body mass index (BMI). All women with TV cervical length women in the present study, and the TA cervical length was closely correlated with the TV cervical length. The use of TA ultrasound could be an effective initial tool for cervical length screening in low-risk pregnant women. TA cervical length TV ultrasound. Copyright © 2015. Published by Elsevier B.V.

    The aim of this study was to create a prediction model using data mining approach to identify low risk individuals for incidence of type 2 diabetes, using the Tehran Lipid and Glucose Study (TLGS) database. For a 6647 population without diabetes, aged ≥20 years, followed for 12 years, a prediction model was developed using classification by the decision tree technique. Seven hundred and twenty-nine (11%) diabetes cases occurred during the follow-up. Predictor variables were selected from demographic characteristics, smoking status, medical and drug history and laboratory measures. We developed the predictive models by decision tree using 60 input variables and one output variable. The overall classification accuracy was 90.5%, with 31.1% sensitivity, 97.9% specificity; and for the subjects without diabetes, precision and f-measure were 92% and 0.95, respectively. The identified variables included fasting plasma glucose, body mass index, triglycerides, mean arterial blood pressure, family history of diabetes, educational level and job status. In conclusion, decision tree analysis, using routine demographic, clinical, anthropometric and laboratory measurements, created a simple tool to predict individuals at low risk for type 2 diabetes.

    Objective: To assess the body mass index and waist circumferences of high risk non diabetic young individuals and compare them with low risk non diabetic young individuals. Method: A cross sectional, case control comparative study was conducted in the department of medicine, LUMHS from January 2008 to March 2009. Five hundred individuals 20-40 years of age were selected and divided into two groups i.e. Group A: high risk (250 individuals) and Group B: low risk (250 individuals) on the basis of same age and gender. Group A included those who had positive family history of type 2 DM in first degree relatives while group B had no family history of type 2 DM in first degree relatives. The blood pressure, BMI and Waist Circumference was measured and Fasting Blood Sugar was estimated in each individual. In each group 125 (50%) were males and 125 (50%) were females. Results: In group A 58% and in group B 28.8% individuals represented raised BMI whereas 42% in group A and 36% in group B individuals showed an increased waist circumference. Mean fasting blood glucose was significantly higher in Group A than in Group B (P=0.001). Conclusion: Impaired Fasting Glucose is strongly associated with family history of type 2 diabetes mellitus. Presence of obesity specially in high risk non-diabetic young individuals emphasize the need for routine health screening for early institution of preventive measures. (author)

    2012-02-01

    OBJECTIVE: To ascertain the impact of placental architecture on antenatal course and labor delivery in a low-risk primigravid population. METHODS: This study involves prospective recruitment of 1011 low-risk primigravids with placental ultrasound at 22?24 weeks and 36 weeks. Detailed postnatal review of all mothers and infants was undertaken. Retrospective analysis of ultrasound and clinical outcome data was performed. RESULTS: Eight hundred ten women with complete outcome data were available. Anterior placentation was statistically associated with intrauterine growth restriction (IUGR) and preterm birth and fundal placentation was significantly associated with a higher incidence of pregnancy-induced hypertension and infants with a birthweight less than the 9th centile. Placental infarcts in the third trimester was significantly increased in cases complicated by pre-eclampsia (PET) and in cases with fetal acidosis. Placental calcification was associated a 40-fold increase in the incidence of IUGR. Placental lakes in the second trimester were more prevalent in patients with threatened miscarriage. Increased placental thickness was associated with a higher rate of fetal acidosis. The Grannum grade of the placenta was higher with threatened first or second trimester loss, PET and in infants born less than 9th centile for gestation. CONCLUSION: Placental site and architecture impact on the incidence of maternal and fetal disease.

    To explore attitudes of physicians attending births in the public and private sectors and at the managerial level toward cesarean birth in Nicaragua. A qualitative study was conducted consisting of four focus groups with 17 physicians and nine in-depth interviews with decision-makers. Although study participants listed many advantages of vaginal birth and disadvantages of cesarean birth, they perceived that the increase in the cesarean birth rate in Nicaragua has resulted in a reduction in perinatal morbidity and mortality. They ascribed high cesarean birth rates to a web of interrelated provider, patient, and health system factors. They identified five actions that would facilitate a reduction in the number of unnecessary cesarean operations: establishing standards and protocols; preparing women and their families for labor and childbirth; incorporating cesarean birth rate monitoring and audit systems into quality assurance activities at the facility level; strengthening the movement to humanize birth; and promoting community-based interventions to educate women and families about the benefits of vaginal birth. Study participants believe that by performing cesarean operations they are providing the best quality of care feasible within their context. They do not perceive problems with their current practice. The identified causes of unnecessary cesarean operations in Nicaragua are multifactorial, so it appears that a multi-layered strategy is needed to safely reduce cesarean birth rates. The recent Nicaraguan Ministry of Health guidance to promote parto humanizado ("humanization of childbirth") could serve as the basis for a collaborative effort among health care professionals, government, and consumer advocates to reduce the number of unnecessary cesarean births in Nicaragua.

  1. A low-risk aqueous lithium salt blanket for engineering test reactors

    Gierszewski, P.

    1986-09-01

    A simple blanket concept is proposed based on 1-3 wt.% lithium dissolved as a salt in low temperature (80 degrees C) and low pressure (0.1 MPa) water. This concept can provide, for example, a 0.5 tritium breeding ratio with 60% steel structure and 70% coverage. The use of neutron multipliers, other structural materials (especially zirconium alloys), higher coverage and higher lithium salt concentrations allows tritium breeding ratios over unity if necessary. Other advantages of this concept include the simple shield-like geometry, substantial structural volume for mechanical strength, excellent heat transfer ability of water coolant, efficient neutron and gamma shielding through the combination of high-Z structure and low-Z water, and conventional tritium recovery and control technology. This concept could initially provide the shielding needs for an engineering test reactor and later, by the addition of lithium salt and tritium recovery systems, also provide tritium breeding. This staged operation and liquid breeder/coolant allows control over the tritium inventory in the device without machine disassembly. 14 refs

    Periodontal disease has been associated with systemic inflammation and adverse pregnancy outcomes, including preeclampsia and preterm birth. To examine the relationship between periodontal disease in early pregnancy and the risk of amniotic inflammation, preterm birth, and preeclampsia. We performed a prospective cohort study of women undergoing amniocentesis for fetal karyotype between 15 and 24 weeks' gestation. Participants underwent periodontal examination by a certified dentist, and a sample of amniotic fluid was collected. Periodontal disease was defined as the presence of one or more sites with probing depths ≥ 4 mm and ≥ 10% bleeding on probing. Matrix metalloproteinase-8 and interleukin-6 concentrations in the amniotic fluid were measured. Medical charts were reviewed for perinatal outcomes. Univariate and multivariate logistic regression analyses were used to assess the association between periodontal disease and adverse pregnancy outcomes. We recruited 273 women at a median gestational age of 16 weeks (range 15 to 24), and 258 (95%) agreed to undergo periodontal examination. Periodontal disease was observed in 117 of the participants (45%). We observed no significant association between periodontal disease and preterm birth (relative risk [RR] 2.27; 95% CI 0.74 to 6.96) or spontaneous preterm birth (RR 0.90; 95% CI 0.20 to 4.11). However, women with periodontal disease were more likely to develop preeclampsia, and this association remained significant after adjustment for potential confounders (adjusted RR 5.89; 95% CI 1.24 to 28.05). Periodontal disease was not associated with significant differences in the intra-amniotic concentration of matrix metalloproteinase-8 (13.0 ± 46.6 vs 5.7 ± 10.4 ng/mL, P = 0.098) or interleukin-6 (3.3 ± 20.3 vs 1.0 ± 1.6 ng/mL, P = 0.23), although a non-significant trend was observed. Periodontal disease is associated with preeclampsia but not with spontaneous preterm birth. The current study cannot exclude an

    To investigate whether the type of programmed cell death of myelodysplastic erythroid cells depends on their cellular context, we performed studies on cells from patients with low-risk myelodysplastic syndromes. We compared erythroid cells (and their precursor cells) from the mononuclear cell fraction with those from the hematon fraction, which are compacted complexes of hematopoietic cells surrounded by their own micro-environment. In directly fixed materials, erythroblasts exhibited signs of autophagy with limited apoptosis (micro-environment was noted for immature erythroid progenitor cells. Myelodysplastic hematons exhibited distinct numbers of erythroid burst-forming units in association with an extensive network of stromal cells, whereas small numbers of erythroid burst-forming units were generated from the myelodysplastic mononuclear cells compared with normal mononuclear cells (10.2 ± 9 vs. 162 ± 125, p micro-environment.

    This study examined how parenting style at 9 months predicts growth in infant social engagement (i.e., social smiling) between 9 and 18 months during a free-play interaction in infants at high (HR-infants) and low (LR-infants) familial risk for autism spectrum disorder (ASD). Results indicated that across all infants, higher levels of maternal responsiveness were concurrently associated with higher levels of social smiling, while higher levels of maternal directiveness predicted slower growth in social smiling. When accounting for maternal directiveness, which was higher in mothers of HR-infants, HR-infants exhibited greater growth in social smiling than LR-infants. Overall, each parenting style appears to make a unique contribution to the development of social engagement in infants at high- and low-risk for ASD.

    Though a minority of patients presenting to the emergency department with chest pain have acute coronary syndromes,identifying the patients who may be safely discharged and determining whether further testing is needed remains challenging. From the prehospital care setting to disposition and follow-up, this systematic review addresses the fundamentals of the emergency department evaluation of patients determined to be at low risk for acute coronary syndromes or adverse outcomes. Clinical risk scores are discussed, as well as the evidence and indications for confirmatory testing. The emerging role of new technologies, such as high-sensitivity troponin assays and advanced imaging techniques, are also presented. [Points & Pearls is a digest of Emergency Medicine Practice].

    Full Text Available This study investigated the effect of routine second-trimester ultrasound scanning on obstetric management and pregnancy outcomes. This was an open cluster, randomised, controlled trial. Clusters of women with low-risk pregnancies presenting in the second trimester were randomised to receive an ultrasound scan followed by usual antenatal care, or to an unscanned control group undergoing conventional antenatal care only. Out of the 962 women randomised, follow-up was successful for 804 (83.6%, with 416 allocated to the ultrasound scan group and 388 controls. There were no significant differences between the ultrasound scan group and the control group in terms of prenatal hospitalisation, mode of delivery, miscarriage, perinatal mortality rate and low birthweight rate. Ultrasound dating was associated with a lower rate of induction of labour for post-term pregnancy (1.4% vs. 3.6%; P=0.049. However, ultrasound scanning in low-risk pregnancies was not associated with improvements in pregnancy outcome.

    To describe aspects of expectant midwifery care for low-risk women conducted in midwifery-managed birth centres during the first two critical hours after delivery and to compare differences between midwifery care, client factors and postpartum blood loss volume. As a secondary analysis from a larger study, this descriptive retrospective study examined data from birth records of 4051 women who birthed from 2001 to 2006 at nine (21%) of the 43 midwifery centres in Tokyo. Nonparametric and parametric analyses identified factors related to increased blood loss. Interviews to establish sequence of midwifery care were conducted. The midwifery centres provided care based on expectant management principles from birth to after expulsion of the placenta. Approximately 63.3% of women were within the normal limits of blood loss volume under 500g. A minority of women (12.9%) experienced blood loss between 500 and 800g and 4% had blood loss exceeding 1000g. Blood loss volume tended to increase with infant birth weight and duration of delivery. The total blood loss volume was significantly higher for primiparas than for multiparas during the critical two hours after delivery and for immediately after delivery, yet blood loss volume was significantly higher for multiparas than for primiparas during the first hour after delivery. Preventive uterine massage and umbilical cord clamping after placenta expulsion resulted in statistically significant less blood loss. Identified were two patterns of midwifery care based on expectant management principles from birth to after expulsion of the placenta. The practice of expectant management was not a significant factor for increased postpartum blood loss. These results detail specific midwifery practices and highlight the clinical significance of expectant management with low risk pregnant women experiencing a normal delivery.

    Purpose: To examine the outcomes of Southeast Asian (SEA) women with low-risk ductal carcinoma in situ (DCIS) treated with breast-conserving surgery (BCS) and adjuvant radiation therapy. Methods and Materials: Retrospective chart reviews of patients treated with BCS for DCIS from 1995 to 2011 were performed. Patients meeting the selection criteria from Eastern Cooperative Oncology Group 5194 were included. Most patients received adjuvant radiation therapy (RT) consisting of whole-breast RT delivered to 50 Gy followed by a 10-Gy boost to the tumor bed. Results: Of 744 patients with pathologic diagnosis of pure DCIS identified, 273 met the selection criteria: low-intermediate grade (LIG), n=219; high grade (HG), n=54. Median follow-up for these patients was 60 months. There were 8 ipsilateral breast tumor recurrences (IBTRs) in total, 7 of which were DCIS. The estimated actuarial IBTR rates at 5 and 10 years for the entire cohort are 1.8% and 4.3%, respectively. Of the 219 patients with LIG DCIS, 210 received RT and 9 did not. There were 7 IBTRs in LIG DCIS, 2 among the 9 patients who did not receive RT. The IBTR rates in LIG DCIS at 5 and 10 years are 2.3% and 4.2%, respectively. All patients with HG DCIS received RT. There was only 1 IBTR occurring beyond 5 years, giving an estimated IBTR rate of 4.5% at 10 years. Conclusions: SEA women with screen-detected DCIS have exceedingly low rates of IBTR after BCS, comparable to that observed in reports of similar patients with low-risk DCIS treated with adjuvant radiation

    To evaluate the role of Transperineal Template guided Mapping Biopsy (TTMB) in determining the management strategy in patients with low risk prostate cancer (PCa). We retroscpectively evaluated 169 patients who underwent TTMB at our institution from February 2008 to June 2011. Ninety eight of them harbored indolent PCa defined as: Prostate Specific Antigen<10ng/ml, Gleason score 6 or less, clinical stage T2a or less, unilateral disease and a maximum of one third positive cores at first biopsy and<50% of the core involved. TTMB results were analyzed for Gleason score upgrading and upstaging as compared to initial TransRectal UltraSound (TRUS) biopsies and its influence on the change in the treatment decisions. TTMB detected cancer in 64 (65%) patients. The upgrade, upstage and both were noted in 33% (n=21), 12% (n=8) and 7% (n=5) respectively of the detected cancers. The disease characteristics was similar to initial TRUS in 30 (48%) patients and TTMB was negative in 34 (35%) patients. Prostate volume was significantly smaller in patients with upgrade and/or upstage noted at TTMB (45.4 vs 37.9; P=.03). TTMB results influenced 73.5% of upgraded and/or upstaged patients to receive radical treatment while 81% of the patients with unmodified stage and/or grade continued active surveillance or focal therapy. In patients with low risk PCa diagnosed by TRUS, subsequent TTMB demonstrated cancer upgrade and/or upstage in about one-third of the patients and resulted in eventual change in treatment decision.

    The Red Sea generally, despite all of the necessary components for tsunami production, has been generally defined as 'low-risk' with regard to tsunami damage on the basis of historical records, observations of small-scale tsunami production in recent periods, and a lack of field evidence. While some regions are known to be prone to tsunami events, other areas are considered safe because of their geographic and bathymetric settings, seismic disposition, and lack of written descriptions of past tsunamis. Models that are produced to estimate said risk rely on catalogues of written records and field studies that summarize known events. There are multiple failures in this approach. First, written records are not evenly distributed worldwide, nor has writing always existed; thereby limiting the possible timeframe for reference. Field studies of preserved tsunami deposits focus primarily on terrestrial or coastal deposits, which modern observations of post-tsunami deposit diagenesis are determining that they are quickly eroded and rarely preserved, thus leading to a considerably patchy record, ultimately underrepresenting the actual number of past tsunamis. Offshore sedimentary deposits may hold promise as better recorders of these events. Here we present recently published evidence for a rare, yet significant and potentially very destructive tsunami event that impacted a presumed low-risk location in the northern Red Sea's Gulf of Aqaba. The anomalous deposits were recognized within sediment cores collected offshore (-16 to -12 msl) and were identified using a suite of common tsunamigenic indicators such as sedimentological characterization, granulometry and micropaleontology. Given rapidly expanding coastal populations in the region and worldwide, these findings are a warning that the current practice of determining risk based solely on models and historical catalogues, without offshore field studies, is insufficient.

    To characterize risk for opioid misuse among gynecologic oncology patients. The Opioid Risk Tool (ORT), a validated screen for opioid misuse risk, was administered to a convenience sample of patients with gynecologic cancer receiving opioid prescriptions in gynecologic oncology or palliative care clinics from January 2012-June 2016. Demographic and clinical information was abstracted on chart review. The primary outcome was ORT risk level (low vs. moderate or high). Chi-square tests were performed for categorical variables. A total of 118 women were screened. Most women were Caucasian (79%) with a median age of 57years. Ovarian cancer patients comprised 46% of the cohort with fewer endometrial (25%), cervical (23%), vulvar (4%), and vaginal (2%) cancer patients. The median ORT score was 1.0 (range, 0-10) out of a possible 26. Overall, 87% of patients were categorized as low-risk for opioid misuse, 7% as moderate-risk, and 6% as high-risk. Patients who were at moderate or high-risk of opioid misuse were significantly younger (47 vs. 58years, p=0.02), more likely to have cervical cancer (p=0.02), be smokers (p=0.01) and be uninsured or on Medicare (p=0.03). Most gynecologic oncology patients in our cohort were low-risk for opioid misuse (87%). Cervical cancer patients were more likely to be moderate to high-risk for misuse. Future screening efforts for opioid misuse may have the highest utility in this subset of patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To investigate the contribution of obstetric risk factors to persistent urinary incontinence (UI) between 4 and 18 months postpartum. Prospective pregnancy cohort. Six metropolitan public hospitals in Victoria, Australia. A total of 1507 nulliparous women recruited to the Maternal Health Study in early pregnancy (≤24 weeks of gestation). Data from hospital records and self-administered questionnaires/telephone interviews at ≤24 and 30-32 weeks of gestation and at 3, 6, 9, 12 and 18 months postpartum analysed using logistic regression. Persistent UI 4-18 months postpartum in women continent before pregnancy. Of the women who were continent before pregnancy, 44% reported UI 4-18 months postpartum, and 25% reported persistent UI (symptoms at multiple follow ups). Compared with spontaneous vaginal birth, women who had a caesarean before labour (adjusted odds ratio [aOR] 0.4, 95% confidence interval [95% CI] 0.2-0.9), in first-stage labour (aOR 0.4, 95% CI 0.2-0.6) or in second-stage labour (aOR 0.4, 95% CI 0.2-1.0) were less likely to report persistent UI 4-18 months postpartum. Prolonged second-stage labour in women who had an operative vaginal birth was associated with increased likelihood of UI (aOR 2.5, 95% CI 1.3-4.6). Compared with women who were continent in pregnancy, women reporting UI in pregnancy had a seven-fold increase in odds of persistent UI (aOR 7.4, 95% CI 5.1-10.7). Persistent UI is common after childbirth and is more likely following prolonged labour in combination with operative vaginal birth. The majority of women reporting persistent UI at 4-18 months postpartum also experienced symptoms in pregnancy. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

Prospective pregnancy cohort. Six metropolitan public hospitals in Victoria, Australia. A total of 1507 nulliparous women recruited to the maternal health study in early pregnancy (≤24 weeks). Data from hospital medical records and self-administered questionnaires/telephone interviews at ≤24 and 30-32 weeks of gestation and 3 months postpartum analysed using univariable and multivariable logistic regression. Urinary incontinence 3 months postpartum in women continent before the index pregnancy. Of the women continent before pregnancy, 26% reported new incontinence at 3 months postpartum. Compared with women who had a spontaneous vaginal birth, women who had a caesarean section before labour (adjusted odds ratio [OR] 0.2, 95% CI 0.1-0.5) or in the first stage of labour (adjusted OR 0.2, 95% CI 0.1-0.4) were less likely to be incontinent 3 months postpartum. Adjusted OR for incontinence after caesarean section in the second stage of labour compared with spontaneous vaginal birth was 0.5 (95% CI 0.2-1.0). Prolonged second stage labour was associated with increased likelihood of postpartum incontinence in women who had a spontaneous vaginal birth (adjusted OR 1.9, 95% CI 1.1-3.4) or operative vaginal birth (adjusted OR 1.7, 95% CI 1.0-2.8). In addition to pregnancy itself, physiological changes associated with the second stage of labour appear to play a role in postpartum urinary incontinence. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

Written questionnaires were completed at recruitment and at three, six and 12 months post partum. Edinburgh Postnatal Depression Scale (EPDS); standardised measures of urinary and faecal incontinence, a checklist of symptoms for other physical health problems. overall, 16.1% of women reported depressive symptoms during the first 12 months post partum, with point prevalence at three, six and 12 months post partum of 6.9%, 8.8% and 7.8% respectively. The most commonly reported physical health problems in the first three months were tiredness (67%), back pain (47%), breast problems (37%), painful perineum (30%), and urinary incontinence (29%). Compared with women reporting 0-2 health problems in the first three months post partum, women reporting 5 or more health problems had a six-fold increase in likelihood of reporting concurrent depressive symptoms at three months post partum (Adjusted OR=6.69, 95% CI=3.0-15.0) and a three-fold increase in likelihood of reporting subsequent depressive symptoms at 6-12 months post partum (Adjusted OR=3.43, 95% CI 2.1-5.5). poor physical health in the early postnatal period is associated with poorer mental health throughout the first 12 months post partum. Early intervention to promote maternal mental health should incorporate assessment and intervention to address common postnatal physical health problems. Copyright © 2013 Elsevier Ltd.

Using a cross-sectional study in patients treated in clinical laboratory of the Sanitary District no. 7 of the city of Orizaba during the months June-July, 252 urine samples were collected for the identification of T. vaginalis and C. albicans by PCR. Furthermore, we analyzed the sociodemographic characteristics of the studied population. We observed an overall prevalence of 23.41% (95% CI 22.10–24.72 for T. vaginalis and 38.88% (95% CI 37.73–40.03 for C. albicans. There was also presence of coinfection in 14.28% (95% CI 13.10–15.46, which was associated with the presence of pain. Most of the positive cases were observed in women house-maker (80%, 95% CI 50.36–48.98. The results of this study provide evidence that the majority of positive cases observed in the studied population are presented in an asymptomatic form and usually are not associated with any risk factor.

    The purpose of this study was to test whether immunohistochemical (IHC) Ki67 levels after short-term preoperative hormone therapy (post-Ki67) predict similar numbers of patients with favorable prognoses as genomic markers. Thirty paired cases (60 samples) were enrolled in this study. Post-Ki67 levels were significantly lower than pre-treatment Ki67 levels (P Ki67 predicted more low-risk cases (83.3%, 25/30) than pre-genomic surrogate signature(GSS) (66.7%: 20/30), but the difference in predictive power was not significant (P = 0.233). Proliferation (MKI67, STK15, Survivin, CCNB1, and MYBL2) and estrogen (ER, PGR, BCL2, and SCUBE2) related signatures were significantly downregulated after therapy (P breast cancer were collected at Okayama University Hospital from hormone receptor-positive and human epidermal growth factor 2-negative patients that subsequently received two weeks of neoadjuvant hormone therapy. Paired post-treatment specimens from surgical samples were also collected. IHC Ki67 levels and GSS were compared between pre- and post-hormone treatment samples. Changes of gene expression pattern in short-term hormone therapy were also assessed. IHC based post-Ki67 levels may have distinct predictive power compared with the naïve IHC Ki67. Future studies with larger cohorts and longer follow-up periods may be needed to validate our results.

    The objective of this study was to assess low-risk very low birth weight (VLBW) children, before the era of modern neonatal intensive care in Turkey, during adolescence. Forty-one VLBW adolescents were compared with 40 adolescents who had normal birth weight. The physical and neuromotor development, educational achievement and psychosocial status were assessed at a mean age of 17 +/- 1.6 years. VLBW adolescents were shorter than normal birth weight adolescents (p = 0.01). A major neurological abnormality (cerebral palsy) was seen in 12% and a minor neurological abnormality (tremor, coordination, behavioral and speech disorders) in 17%. VLBW adolescents had higher rates of visual problems (56% vs. 5%). School failure was present in 27%. There were no differences in behavioral problems or quality of life between the two groups, but VLBW adolescents did have a lower self-esteem score. Neurodevelopment and growth sequelae were a significant problem in VLBW adolescents. As early intervention might help to prevent or ameliorate potential problems, long-term follow-up is essential.

    2016-03-01

    Even though more than 90% of adolescents with low-risk classical Hodgkin lymphoma (LRcHL) will be cured with first-line therapy, many will suffer serious late toxic effects from radiotherapy (RT). The goals for care have shifted toward minimizing late toxic effects without compromising the outstanding cure rates by adapting a risk and response-based therapy. Recent published and ongoing randomized clinical trials, using functional imaging, may allow for better identification of those patients for whom RT may be safely omitted while maintaining excellent cure rates. To evaluate the best chemotherapy regimens with a reasonable toxicity profile and that are expected to have a high chance of omitting RT based on a response-directed therapy while maintaining high cure rates, a mini review was conducted of the recent clinical trials in pediatric and adult LRcHL. The UK RAPID trial chemotherapy backbone (3 × ABVD) followed by a response-based positron emission tomography scan offers up to a 75% chance of safely omitting RT without compromising the cure rate, which remained well above 90%.

    Full Text Available The pathogenic role of mesenchymal stromal cells (MSCs in myelodysplastic syndromes (MDS development and progression has been investigated by numerous studies, yet, it remains controversial in some aspects (1, 2. In the present study, we found distinct features of MSCs from low-risk (LR-MDS stromal microenvironment as compared to those from healthy subjects. At the molecular level, focal adhesion kinase, a key tyrosine kinase in control of cell proliferation, survival, and adhesion process, was found profoundly suppressed in expression and activation in LR-MDS MSC. At a functional level, LR-MDS MSCs showed impaired growth and clonogenic capacity, which were independent of cellular senescence and apoptosis. The pro-adipogenic differentiation and attenuated osteogenic capacity along with reduced SDF-1 expression could be involved in creating an unfavorable microenvironment for hematopoiesis. In conclusion, our experiments support the theory that the stromal microenvironment is fundamentally altered in LR-MDS, and these preliminary data offer a new perspective on LR-MDS pathophysiology.

    Full Text Available Psychological distress, defined as depression, anxiety, and insomnia in this study, can occur following the birth of a baby as new mothers, in addition to marked physiological changes, are faced with adapting to new roles and responsibilities. We investigated the cooccurrence of stress, depression, anxiety, and insomnia in mothers during the postpartum period; tested the feasibility of study methods and procedures for use in this population; and identified new mothers interest in using cranial electrotherapy stimulation (CES as an intervention for reducing psychological distress. We recruited healthy, low-risk, English speaking first-time mothers, ages 18–32 years, with healthy babies (N=33, within 12 months of an uncomplicated birth. Participants completed the PSS, HAM-D14, HAM-A17, and PSQI19. No problems were encountered with study procedures. Mothers reported a high interest (4.9 in the potential use of CES to treat or prevent the occurrence of psychological distress. All participants (N=33 reported moderate levels of depression and anxiety, while 75.8% (n=25 reported insomnia. PSS scores were within the norms for healthy women. Further research is recommended to investigate if our findings can be replicated or if different patterns of associations emerge. Implications for clinical practice are addressed.

    BACKGROUND: We assess our long-term experience with regards the safety and efficacy of Mycophenolate Mofetil (MMF) in our low risk renal transplant population and compared it retrospectively to Azathioprine (AZA) immunosuppressive regimen. Patients and methods. Between January 1999 and December 2005, 240 renal transplants received MMF as part of their immunosuppressive protocol (MMF group). AZA group of 135 renal transplants was included for comparative analysis (AZA group). Patients received Cyclosporine was excluded from this study. RESULTS: The incidence of biopsy proven 3-month acute rejections was 30 (12.5%) in MMF group and 22 (16%) in AZA group respectively (P = 0.307). Patient survival rates at 1 and 5 years for the MMF group were 97 and 94%, respectively, compared to 100% and 91% at 1 and 5 years respectively for the AZA group (P = 0.61). Graft survival rates at 1 and 5 years for the MMF group were 95 and 83%, respectively, compared to 97 and 84% at 1 and 5 years, respectively for the AZA group (P = 0.62). CONCLUSION: There was no difference in acute rejection episodes between MMF and AZA based immunotherapy. Additionally, we observed no significant difference concerning graft survival in the MMF group when compared to AZA group.

RESULTS: The incidence of biopsy proven 3-month acute rejections was 30 (12.5%) in MMF group and 22 (16%) in AZA group respectively (P = 0.307). Patient survival rates at 1 and 5 years for the MMF group were 97 and 94%, respectively, compared to 100% and 91% at 1 and 5 years respectively for the AZA group (P = 0.61). Graft survival rates at 1 and 5 years for the MMF group were 95 and 83%, respectively, compared to 97 and 84% at 1 and 5 years, respectively for the AZA group (P = 0.62). CONCLUSION: There was no difference in acute rejection episodes between MMF and AZA based immunotherapy. Additionally, we observed no significant difference concerning graft survival in the MMF group when compared to AZA group.

    Full Text Available Abstract Background To evaluate the effectiveness and safety of water aerobics during pregnancy. Methods A randomized controlled trial carried out in 71 low-risk sedentary pregnant women, randomly allocated to water aerobics or no physical exercise. Maternal body composition and perinatal outcomes were evaluated. For statistical analysis Chi-square, Fisher's or Student's t-tests were applied. Risk ratios and their 95% CI were estimated for main outcomes. Body composition was evaluated across time using MANOVA or Friedman multiple analysis. Results There were no significant differences between the groups regarding maternal weight gain, BMI or percentage of body fat during pregnancy. Incidence of preterm births (RR = 0.84; 95%CI:0.28–2.53, vaginal births (RR = 1.24; 95%CI:0.73–2.09, low birthweight (RR = 1.30; 95%CI:0.61–2.79 and adequate weight for gestational age (RR = 1.50; 95%CI:0.65–3.48 were also not significantly different between groups. There were no significant differences in systolic and diastolic blood pressure and heart rate between before and immediately after the water aerobics session. Conclusion Water aerobics for sedentary pregnant women proved to be safe and was not associated with any alteration in maternal body composition, type of delivery, preterm birth rate, neonatal well-being or weight.

    The relationship between various dietary constituents and colon cancer has been demonstrated by previous research. This study was conducted to investigate the combined effects of several dietary constituents on the preneoplastic stage of azoxymethane (AOM)-induced colon cancer in rats. A nutritionally adequate, "low-risk" (LR) diet was formulated through the modulation of dietary fat, fiber, protein, vitamins A and E, and selenium. Female F344 rats were given three weekly subcutaneous injections of AOM and were maintained on either the LR diet or a "high-risk" (HR) diet. After 12 weeks, the rats were killed and the following parameters were determined: pH of colon contents, fecal beta-glucuronidase activity, tissue ornithine decarboxylase (ODC) activity, and colonic labeling index. The pH of the colon contents and incremental labeling index were lower in the group given the LR diet and treated with AOM compared with the group given the HR diet and treated with AOM; however, no statistically significant dietary effects were observed for beta-glucuronidase and ODC activities. The results of this study indicated that the colons of rats fed the LR diet exhibited different proliferative characteristics than did the colons of rats fed the HR diet.

    Full Text Available Abstract Background The prevalence of asymptomatic bacteriuria (ASB in pregnancy is 2-10% and is associated with both maternal and neonatal adverse outcomes as pyelonephritis and preterm delivery. Antibiotic treatment is reported to decrease these adverse outcomes although the existing evidence is of poor quality. Methods/Design We plan a combined screen and treat study in women with a singleton pregnancy. We will screen women between 16 and 22 weeks of gestation for ASB using the urine dipslide technique. The dipslide is considered positive when colony concentration ≥105 colony forming units (CFU/mL of a single microorganism or two different colonies but one ≥105 CFU/mL is found, or when Group B Streptococcus bacteriuria is found in any colony concentration. Women with a positive dipslide will be randomly allocated to receive nitrofurantoin or placebo 100 mg twice a day for 5 consecutive days (double blind. Primary outcomes of this trial are maternal pyelonephritis and/or preterm delivery before 34 weeks. Secondary outcomes are neonatal and maternal morbidity, neonatal weight, time to delivery, preterm delivery rate before 32 and 37 weeks, days of admission in neonatal intensive care unit, maternal admission days and costs. Discussion This trial will provide evidence for the benefit and cost-effectiveness of dipslide screening for ASB among low risk women at 16–22 weeks of pregnancy and subsequent nitrofurantoin treatment.

    To determine the effectiveness and cost of antibiotic chemoprophylaxis in reducing infectious morbidity in low-risk women undergoing elective cesarean delivery. A prospective randomized clinical trial was performed at a single tertiary care center in Jinan, China between November 2012 and December 2013. Women were randomized to receive either antibiotic prophylaxis or no antibiotics prior to elective cesarean delivery at term. The infectious morbidity (fever, surgical site infection - SSI, endometritis and urinary tract infection), routine blood tests and hospital costs were measured. Total of 414 women were enrolled into the study; and 202 women received antibiotic chemoprophylaxis and 212 women received no antibiotics. Demographic and clinical characteristics were similar between the two groups. Total of one case in the treatment group and four case in the non-treatment group developed endometritis, giving the postoperative infection rate of 1.2%, which was not statistically significant between the two groups (χ(2) = 1.679, p = 0.195). The secondary outcomes were also not different between the two groups, except the costs of hospitalization, which was significantly higher in the treatment group (p cesarean delivery at term, prophylactic antibiotics did not reduce the risk of postoperative infection, but significantly increased the cost of hospitalization.

    , and its presence on gastric cancer cells is linked to micro-metastasis and poor prognosis. Immunohistochemical analyses of a set of 44 gastric cancer lesions from Costa Rica showed expression of uPAR in cancer cells in both intestinal subtype (14 of 27) and diffuse subtype (10 of 17). We compared...... the expression pattern of uPAR in gastric cancers from a high-risk country (Costa Rica) with a low-risk country (Norway). We found uPAR on gastric cancer cells in 24 of 44 cases (54%) from Costa Rica and in 13 of 23 cases (56%) from Norway. uPAR was seen in macrophages and neutrophils in all cases. We also......PAR in cancer cells in more than half of the gastric cancer cases suggests that their uPAR-positivity do not contribute to explain the different mortality rates between the 2 countries, however, the actual prevalence of uPAR-positive cancer cells in the gastric cancers may still provide prognostic information....

    We derive and validate clinical prediction rules to identify adult patients at very low risk for intra-abdominal injuries after blunt torso trauma. We prospectively enrolled adult patients (>or=18 years old) after blunt torso trauma for whom diagnostic testing for intra-abdominal injury was performed. In the derivation phase, we used binary recursive partitioning to create a rule to identify patients with intra-abdominal injury who were undergoing acute intervention (including therapeutic laparotomy or angiographic embolization) and a separate rule for identifying patients with any intra-abdominal injury present. We considered only clinical variables readily available with acceptable interrater reliability. The prediction rules were then prospectively validated in a separate cohort of patients. In the derivation phase, we enrolled 3,435 patients, including 311 (9.1%; 95% confidence interval [CI] 8.1% to 10.1%) with intra-abdominal injury and 109 (35.0%; 95% CI 29.7% to 40.6%) with intra-abdominal injury requiring acute intervention. In the validation study, we enrolled 1,595 patients, including 143 (9.0%; 95% CI 7.6% to 10.5%) with intra-abdominal injury. The derived rule for patients with intra-abdominal injuries who were undergoing acute intervention consisted of hypotension, Glasgow Coma Scale (GCS) score less than 14, costal margin tenderness, abdominal tenderness, hematuria level greater than or equal to 25 red blood cells/high powered field, and hematocrit level less than 30% and identified all 44 patients in the validation phase with intra-abdominal injury who were undergoing acute intervention (sensitivity 44/44, 100%; 95% CI 93.4% to 100%). The derived rule for the presence of any intra-abdominal injury consisted of GCS score less than 14, costal margin tenderness, abdominal tenderness, femur fracture, hematuria level greater than or equal to 25 red blood cells/high powered field, hematocrit level less than 30%, and abnormal chest radiograph result

    To investigate the multiparametric prostate magnetic resonance imaging (mpMRI) findings in patients treated with testosterone replacement therapy (TRT) while on active surveillance for low-risk prostate cancer. We retrospectively reviewed 12 patients who underwent mpMRI before and after TRT while on active surveillance. Changes in serum testosterone level, prostate-specific antigen (PSA), prostate biopsy findings, prostate volume, and Prostate Imaging Reporting and Data System Version 2 (PI-RADSv2) score before and after TRT were summarized. After TRT, there was a significant increase in serum testosterone (516.5ng/dl vs. 203.0ng/dl), PSA (4.2ng/ml vs. 3.3ng/ml), and prostate volume (55.2cm 3 vs. 39.4cm 3 ). In total, 2 patients had biopsy progression during the study period. The PI-RADSv2 scores before and after TRT were unchanged in 10/12 patients; none of these demonstrated biopsy progression on post-TRT. The PI-RADSv2 scores increased after TRT in 2/12 patients; both showed Gleason score upgrade on follow-up biopsy. Of these 2 patients, 1 patient underwent radical treatment due to clinical progression. The area under the curve for detecting biopsy progression calculated from PI-RADSv2 score after TRT was 0.90, which was better than that calculated from post-TRT PSA level (0.48). After TRT, mpMRI findings remained stable in patients without biopsy progression, whereas PI-RADSv2 score increase was identified in patients with Gleason score upgrade on follow-up biopsy.

    The incidence of thyroid cancer is increasing rapidly in many countries, resulting in rising societal costs of the care of thyroid cancer. We reported that the active surveillance of low-risk papillary microcarcinoma had less unfavorable events than immediate surgery, while the oncological outcomes of these managements were similarly excellent. Here we calculated the medical costs of these two managements. We created a model of the flow of these managements, based on our previous study. The flow and costs include the step of diagnosis, surgery, prescription of medicine, recurrence, salvage surgery for recurrence, and care for 10 years after the diagnosis. The costs were calculated according to the typical clinical practices at Kuma Hospital performed under the Japanese Health Care Insurance System. If conversion surgeries were not considered, the 'simple cost' of active surveillance for 10 years was 167,780 yen/patient. If there were no recurrences, the 'simple cost' of immediate surgery was calculated as 794,770 yen/patient to 1,086,070 yen/patient, depending on the type of surgery and postoperative medication. The 'simple cost' of surgery was 4.7 to 6.5 times the 'simple cost' of surveillance. When conversion surgeries and recurrence were considered, the 'total cost' of active surveillance for 10 years became 225,695 yen/patient. When recurrence were considered, the 'total cost' of immediate surgery was 928,094 yen/patient, which was 4.1 times the 'total cost' of the active surveillance. At Kuma Hospital in Japan, the 10-year total cost of immediate surgery was 4.1 times expensive than active surveillance.

    Recent Children's Oncology Group trials for low-risk rhabdomyosarcoma attempted to reduce therapy while maintaining excellent outcomes. D9602 delivered 45 weeks of outpatient vincristine and dactinomycin (VA) for patients in Subgroup A. ARST0331 reduced the duration of therapy to 22 weeks but added four doses of cyclophosphamide to VA for patients in Subset 1. Failure-free survival was similar. We undertook a cost minimization comparison to help guide future decision-making. Addressing the costs of treatment from the healthcare perspective we modeled a simple decision-analytic model from aggregate clinical trial data. Medical care inputs and probabilities were estimated from trial reports and focused chart review. Costs of radiation, surgery and off-therapy surveillance were excluded. Unit costs were obtained from literature and national reimbursement and inpatient utilization databases and converted to 2012 US dollars. Model uncertainty was assessed with first-order sensitivity analysis. Direct medical costs were $46,393 for D9602 and $43,261 for ARST0331 respectively, making ARST0331 the less costly strategy. Dactinomycin contributed the most to D9602 total costs but varied with age (42-69%). Chemotherapy administration costs accounted for the largest proportion of ARST0331 total costs (39-57%). ARST0331 incurred fewer costs than D9602 under most alternative distributive models and alternative clinical practice assumptions. Cost analysis suggests that ARST0331 may incur fewer costs than D9602 from the healthcare system's perspective. Attention to the services driving the costs provides directions for future efficiency improvements. Future studies should prospectively consider the patient and family's perspective. © 2014 Wiley Periodicals, Inc.

    Obstetric procedures are among the most expensive health care services, yet relatively little is known about health care spending among pregnant women, particularly the commercially-insured. The objective of this study was to examine the association between maternal medical complexity, as a result of having one or more comorbid conditions, and health care spending during the prenatal period among a national sample of 95,663 commercially-insured women at low risk for cesarean delivery. We conducted secondary analyses of 2010-2011 inpatient, outpatient, and professional claims for health care services from the Health Care Cost Institute. Allowed charges were summed for the prenatal and childbirth periods. Ordinary least squares regressions tested associations between maternal health conditions and health care expenditures during pregnancy. Thirty-four percent of pregnant women had one or more comorbidities; 8% had two or more. Pregnant women with one or more comorbidities had significantly higher allowed charges than those without comorbidities (p prenatal period was nearly three times higher for women with preexisting diabetes compared with women with no comorbid conditions. Average levels of prenatal period spending associated with maternal comorbidities were similar for women who had vaginal and cesarean deliveries. Patient characteristics accounted for 30% of the variance in prenatal period expenditures. The impact of maternal comorbidities, and in particular preexisting diabetes, on prenatal care expenditures should be taken into account as provider payment reforms, such as pay-for performance incentives and bundled payments for episodes of care, extend to maternal and child health-related services.

    Full Text Available Background and Objectives: Postpartum depression is one of most important health problems in women. This study was performed with the purpose of comparing the frequency of postpartum depression in pregnant women with emotion and problem-focused coping strategies. Methods: This study was conducted as a prospective cohort study on 200 pregnant women with stress (low and high levels. The samples were pregnant women referred to all health-treatment, centers of Ardabil, which were selected using a multi-stage sampling method; and according to coping strategy, they were divided into two groups: emotion-focused and problem-focused. Low-risk pregnant women completed questionnaires about demographic characteristics, perceived stress, and Billings and Moos coping strategies in the 38th to 42th week of their pregnancy, and completed the Edinburgh depression scale in the 3th to 4th weeks after childbirth. Data were analyzed using chi 2 and t tests. p<0.05 considered significant.Results: In this study, 170 participant women (85% used emotion-focused strategy and 30 women (15% used problem-focused strategy. Frequency of postpartum depression was 6.7% in the problem-focused group and 8.2% in the emotion-focused group. There was no significant difference in the frequency of postpartum depression between women with the problem- and emotion-focused strategies. Relative risk for postpartum depression was 1.2 times more among the women used emotion-focused strategy than women used problem-focused strategy (p<0.05.Conclusion: According to the results of this study, there was no significant relationship between postpartum depression and the two emotion-focused and problem-focused coping strategies. This can be due to high influence of postpartum specific endocrine factors in the etiology of this type of depression compared to other depressions.

    To determine whether corneal graft survival over a 5-year follow-up period was affected by ABO blood type compatibility in participants in the Cornea Donor Study undergoing corneal transplantation principally for Fuchs dystrophy or pseudophakic corneal edema, conditions at low-risk for graft rejection. Multi-center prospective, double-masked, clinical trial. ABO blood group compatibility was determined for 1,002 donors and recipients. During a 5-year follow-up period, episodes of graft rejection were documented, and graft failures were classified as to whether or not they were attributable to immunologic rejection. Endothelial cell density was determined by a central reading center for a subset of subjects. ABO donor-recipient incompatibility was not associated with graft failure attributable to any cause including graft failure because of rejection, or with the occurrence of a rejection episode. The 5-year cumulative incidence of graft failure attributable to rejection was 32 (6%) for recipients with ABO recipient-donor compatibility and 12 (4%) for those with ABO incompatibility (hazard ratio, 0.65; 95% confidence interval, 0.33 to 1.25; P = .20). The 5-year incidence for a definite rejection episode, irrespective of whether graft failure ultimately occurred, was 64 (12%) for ABO compatible compared with 25 (8%) for ABO incompatible cases (P = .09). Among clear grafts at 5 years, percent loss of endothelial cells was similar in ABO compatible and incompatible cases. In patients undergoing penetrating keratoplasty for Fuchs dystrophy or pseudophakic corneal edema, ABO matching is not indicated since ABO incompatibility does not increase the risk of transplant failure attributable to graft rejection.

    Background: Head and neck squamous cell carcinomas (HNSCC) are a major health issue in many parts of the world. Recently, attention has focused on the human papilloma virus (HPV) as a potential causative agent for HNSCC. This study aimed to survey HPV occurrence in HNSCCs as part of a comprehensive molecular epidemiology approach. Methods: In this retrospective study, patients were recruited from hospitals affiliated to the Iran University of Medical Sciences, Tehran, Iran. Formalin-fixed paraffin-embedded (FFPE) blocks were subjected to DNA isolation by QIAamp® DNA FFPE Tissue Kit and nested PCR, HPV-16 specific conventional PCR, and extra INNO-LiPA HPV genotyping assays were subsequently performed. PCR products were purified with a High Pure PCR Product Purification Kit and sequenced with an ABI 3730 XL sequencer. CLC Main Workbench 5 and MEGA5 bioinformatics software was used to analyze the raw data and to create the phylogenetic tree. SPSS v.20 was applied for statistical analysis. Results: A total of 156 FFPE blocks were collected from 2011 to 2017. Total mean age (y) of participants was 60.5 ± 12.6; 77.6 % (121/156) being men and 22.4% (35/156) e women. Overall, 5/156 (3.2%) patients (3 females and 2 males) were found to be HPV positive using the three methods. HPV genotyping revealed HPV types 16, 2, 27, and 43 in these malignancies. Tumor location and lymph node involvement indicated significant differences between the sexes. Conclusion: Although high risk HPV genotypes have been associated with HNSCCs, our findings indicate a potential of low risk HPV types to also contribute to such malignancies.

    Full Text Available Abstract Background HPV type distribution by cytological status represents useful information to predict the impact of mass vaccination on screening programs. Methods women aged from 25 to 64 who attended cervical cancer screening in five different Italian regions were tested for HPV infection with Hybrid Capture II (HCII low and high risk probes. Women repeating Pap-test upon unsatisfactory or positive results, or as a post-treatment and post-colposcopy follow-up analysis, were excluded from our study. High risk (HR HPV positive samples were typed using GP5+/GP6+ primed PCR, followed by Reverse Line Blot for 18 high/intermediate risk HPV types, while low risk (LR HPV positive samples were tested with type specific primers for HPV6 and HPV11. Results 3410 women had a valid HCII and Pap-test. The prevalence of HR and LR infections was 7.0% and 3.6%, 29.1% and 13.7%, 68.1% and 31.9%, 60.0% and 0.0%, 65.0% and 12.0%, for negative, ASC-US, L-SIL, ASC-H and H-SIL cytology, respectively. The fraction of ASC-US+ cytology due to HPV 16 and 18 ranged from 11.2 (HPV 16/18 alone to 15.4% (including HPV 16/18 in co-infection with other virus strains, and that due to HPV 6 and 11 ranged from 0.2% (HPV 6/11 alone to 0.7% (including HPV 6/11 in co-infection with other LR virus strains. Conclusions mass vaccination with bivalent or quadrivalent HPV vaccine would modestly impact on prevalence of abnormal Pap-test in screening.

    Establish maternal preferences for a third-trimester ultrasound scan in a healthy, low-risk pregnant population. Cross-sectional study incorporating a discrete choice experiment. A large, urban maternity hospital in Northern Ireland. One hundred and forty-six women in their second trimester of pregnancy. A discrete choice experiment was designed to elicit preferences for four attributes of a third-trimester ultrasound scan: health-care professional conducting the scan, detection rate for abnormal foetal growth, provision of non-medical information, cost. Additional data collected included age, marital status, socio-economic status, obstetric history, pregnancy-specific stress levels, perceived health and whether pregnancy was planned. Analysis was undertaken using a mixed logit model with interaction effects. Women's preferences for, and trade-offs between, the attributes of a hypothetical scan and indirect willingness-to-pay estimates. Women had significant positive preference for higher rate of detection, lower cost and provision of non-medical information, with no significant value placed on scan operator. Interaction effects revealed subgroups that valued the scan most: women experiencing their first pregnancy, women reporting higher levels of stress, an adverse obstetric history and older women. Women were able to trade on aspects of care and place relative importance on clinical, non-clinical outcomes and processes of service delivery, thus highlighting the potential of using health utilities in the development of services from a clinical, economic and social perspective. Specifically, maternal preferences exhibited provide valuable information for designing a randomized trial of effectiveness and insight for clinical and policy decision makers to inform woman-centred care. © 2013 Blackwell Publishing Ltd.

    To evaluate in adolescents the association between body mass index (BMI) and obstetric outcomes and to determine whether the outcomes in the BMI groups of adolescents differ from those of a low-risk population of adult women. This is a nationwide population-based register study. Obstetric outcomes of 31,386 singleton primiparous adolescents were evaluated in relation to BMI classes. Furthermore, the outcomes of the adolescents and 178,844 normal weight, nonsmoking, singleton primiparous women, 25-29 years old with no known comorbidity, defined as standard women, were compared. Multiple logistic regression models were used. Results are presented as crude odds ratios (ORs) or adjusted ORs and with a 95% confidence interval. Compared with normal weight adolescents, obese adolescents had a lower chance of a normal vaginal delivery (VD)-76% versus 85% [adjusted OR 0.61 (0.55-0.68)], a higher risk for acute cesarean section (CS)-8.9% versus 4.5% [adjusted OR 2.45 (2.08-2.88)], and stillbirth-0.7% versus 0.2% [adjusted OR 3.17 (1.74-5.77)]. Compared with standard women, overweight adolescents had a higher chance of a normal VD-82% versus 75% [crude OR 1.53 (1.44-1.64)] and a lower risk for acute CS-6.3% versus 7.1% [crude OR 0.85 (0.76-0.95)]. Obese adolescents had a lower risk for instrumental VD-8% versus 13% [crude OR 0.61 (0.53-0.71)] and obstetric anal sphincter injury-1% versus 3% [crude OR 0.38 (0.26-0.57)]. Several adverse obstetric outcomes were obesity related among adolescents. Overweight adolescents seemed to have better obstetric outcomes than standard women, something to consider when optimizing resources for women during pregnancy and delivery.

    Nasopharyngeal cancer (NPC) mortality shows great disparity between endemic high risk areas, where non-keratinizing carcinoma (NKC) histology is prevalent, and non-endemic low risk regions, where the keratinizing squamous cell carcinoma (KSCC) type is more frequent. We used the World Health Organization database to calculate NPC mortality trends from 1970 to 2014 in several countries worldwide. For the European Union (EU), the United States (US) and Japan, we also predicted trends to 2020. In 2012, the highest age-standardized (world standard) rates were in Hong Kong (4.51/100,000 men and 1.15/100,000 women), followed by selected Eastern European countries. The lowest rates were in Northern Europe and Latin America. EU rates were 0.27/100,000 men and 0.09/100,000 women, US rates were 0.20/100,000 men and 0.08/100,000 women and Japanese rates were 0.16/100,000 men and 0.04/100,000 women. NPC mortality trends were favourable for several countries. The decline was -15% in men and -5% in women between 2002 and 2012 in the EU, -12% in men and -9% in women in the US and about -30% in both sexes in Hong Kong and Japan. The favourable patterns in Europe and the United States are predicted to continue. Changes in salted fish and preserved food consumption account for the fall in NKC. Smoking and alcohol prevalence disparities between sexes and geographic areas may explain the different rates and trends observed for KSCC and partially for NKC. Dietary patterns, as well as improvement in management of the disease, may partly account for the observed trends, too. © 2017 UICC.

    The conservative management of upper tract urothelial carcinoma (UTUC) has historically been offered to patients with imperative indications. The recent International Consultation on Urologic Diseases (ICUD) publication on UTUC stratified treatment allocations based on high- and low-risk groups. This report updates the conservative management of the low-risk group. The ICUD for low-risk UTUC working group performed a thorough review of the literature with an assessment of the level of evidence and grade of recommendation for a variety of published studies in this disease space. We update these publications and provide a summary of that original report. There are no prospective randomized controlled studies to support surgical management guidelines. A risk-stratified approach based on clinical, endoscopic, and biopsy assessment allows selection of patients who could benefit from kidney-preserving procedures with oncological outcomes potentially similar to radical nephroureterectomy with bladder cuff excision, with the added benefit of renal function preservation. These treatments are aided by the development of high-definition flexible digital URS, multi-biopsies with the aid of access sheaths and other tools, and promising developments in the use of adjuvant topical therapy. Recent developments in imaging, minimally invasive techniques, multimodality approaches, and adjuvant topical regimens and bladder cancer prevention raise the hope for improved risk stratification and may greatly improve the endoscopic treatment for low-risk UTUC.

    Immigrants have higher risks for some adverse obstetric outcomes, and 40 percent of women giving birth at the low-risk maternity ward in Baerum Hospital, Norway, are immigrants. This study compared obstetric outcomes between immigrants and ethnic Norwegians giving birth in a low-risk setting. This was a population-based study linking the Medical Birth Registry of Norway to Statistics Norway. The study included the first registered birth during the study period to immigrant and ethnic Norwegian women at Baerum Hospital from 2006 to 2010. The main outcome measures were onset of labor, operative vaginal delivery, cesarean delivery, episiotomy, postpartum bleeding > 500 mL, epidural analgesia, labor dystocia, gestational age, meconium-stained liquor, 5-minute Apgar score, birthweight, and transfer to a neonatal intensive care unit. A total of 11,540 women originating from 141 countries were divided into seven groups. Compared with Norwegians, women from East, Southeast, and Central Asia had increased risk for operative vaginal delivery, postpartum bleeding, and low Apgar score. The African women had increased risk for postterm birth, meconium-stained liquor, episiotomy, operative vaginal delivery, emergency cesarean delivery, postpartum bleeding, low Apgar score, and low birthweight. Women from South and Western Asia had increased risk for low birthweight. Obstetric outcomes of immigrants differ significantly from those of Norwegians, even in a low-risk maternity unit. Thus, immigrant women would benefit from more targeted care during pregnancy and childbirth, even in low-risk settings. © 2015 Wiley Periodicals, Inc.

    Full Text Available Purpose — determining the importance of sonographic and Doppler examination after 22 weeks of gestation for the diagnosis of obstetric and perinatal complications at pregnancy low risk. Patients and methods. 4580 pregnant women from low risk subpopulation with normal results of ultrasound screenings. After 22 weeks of gestation sonographic and Doppler studies of pregnancy were performed. Perinatal outcomes of were studied as well. Results. The incidence of pathological ultrasound changes after 22 weeks of gestation in women at low risk subpopulations was 9.8%. Сritical placental violations were found in 51/4580 women (1.13%. In early fetal growth retardation cases at 26–30 weeks of gestation (44/51 or 86.2% the outcomes of pregnancies were unfavorable. In 83.9% cases of placental noncritical violations there were clinically favorable perinatal outcomes. In isolated polyhydramnios favorable outcomes were observed in 61.3% of cases. The risk of intrapartum distress after normal results of the III trimester ultrasound was high: OR 25 (95% CI 29–21, RR 83 (95% CI 77–88. The risk of premature rupture of membranes at normal results of the III trimester ultrasound was also high: OR 35 (95% CI 41–29, RR 88 (95% CI 94–80. Despite the low overall rate (2.5% of identify of uterine artery Doppler changes more than half of women with such disorders had perinatally significant complications which were observed later. An important predictor of preeclampsia and perinatal complications in low-risk pregnancy can be considered a bilateral abnormal uterine artery Doppler in conjunction with early calcification of the placenta: OR 300 (95% CI 278–335, RR 75 (95% CI 71–79. Conclusions. Features revealed by US in the second half of low-risk pregnancy in 3.2% of cases «translate» low'risk pregnancy into the high'risk, and in 6.6% — into the indefinite risk pregnancy. Medical tactics changed less than in 1% of the cases on the basis of ultrasound

    As anemia in pregnancy is associated with adverse perinatal outcomes, we sought to define the mean and the fifth percentile of Hb and Ht using a contemporary multiethnic large cohort of low-risk pregnancies, and assess potential racial differences. We conducted a retrospective cohort study on women who delivered between 1 January 2008 and 31 December 2013 in Reggio Emilia County, Italy. Linear mixed effects models were used to describe changes in mean Hb and Ht, while quantile regression with matrix-design bootstrap defined changes in the fifth percentile of Hb and Ht, controlling for race, maternal age, smoking, and pregnancy number. We analyzed 23,657 hemograms from 7318 pregnancies and 6870 women. Multivariate analysis showed that when compared to Caucasians', African women's mean Hb and Ht were respectively 0.24 (95%CI 0.3-0.17) g/dl and 0.7 (95%CI 0.8-0.5) % lower, while Asian mothers' were 0.11 (95%CI 0.19-0.03) g/dl and 0.3 (95%CI 0.5-0.1) % inferior. Similarly, both African and Asian women had lower fifth Ht percentiles (-1, 95%CI -1.3 to -0.6, and -0.4, 95%CI -0.7 to -0.04) than Caucasians, while African mothers also had lower fifth Hb percentile (0.3, 95%CI 0.5-0.1). The fifth percentile for Hb and Ht were, respectively, 11.3 (95%CI 11-11.5) g/dl and 32.8 (95%CI 32.3-33.4) % in the first trimester, 10.4 (95%CI 10.1-10.6) g/dl and 30.2 (95%CI 29.6-30.8) % in the second trimester, 10.1 (95%CI 9.8-10.3) g/dl and 30.6 (95%CI 30-31.1) % in the third trimester. We provided contemporary references to define anemia in pregnancy, and we confirmed that even in pregnancy, African and Asian women have lower Hb and Ht than Caucasian. Racial and population-specific references may have significant clinical and public health implication for more accurate disease diagnosis and appropriate treatment.

    Prolonged labor is a significant cause of maternal and fetal morbidity and very few interventions are known to shorten labor course. Skeletal muscle physiology suggests that glucose supplementation might improve muscle performance in case of prolonged exercise and this situation is analogous to the gravid uterus during delivery. Therefore, it seemed imperative to evaluate the impact of adding carbohydrate supplements on the course of labor. We sought to provide evidence as to whether intravenous glucose supplementation during labor induction in nulliparous women can reduce total duration of active labor. We performed a single-center prospective double-blind randomized controlled trial comparing the use of parental intravenous dextrose 5% with normal saline to normal saline in induced nulliparous women. The study was conducted in a tertiary-level university hospital setting. Participants, caregivers, and those assessing the outcomes were blinded to group assignment. Inclusion criteria were singleton pregnancy at term with cephalic presentation and favorable cervix. Based on blocked randomization, patients were assigned to receive either 250 mL/h of intravenous dextrose 5% with normal saline or 250 mL/h of normal saline for the whole duration of induction, labor, and delivery. The primary outcome studied was the total length of active labor. Secondary outcomes included duration of the active phase of second stage of labor, the mode of delivery, Apgar scores, and arterial cord pH. In all, 100 patients were randomized into each group. A total of 193 patients (96 in the dextrose with normal saline group and 97 in the normal saline group) were analyzed in the study. The median total duration of labor was significantly less in the dextrose with normal saline group (499 vs 423 minutes, P = .024) than in the normal saline group. The probabilities of a woman being delivered at 200 minutes and 450 minutes were 18.8% and 77.1% in the dextrose with normal saline group vs 8

    2006-01-01

    Objective: To assess the CT and magnetic resonance (MR) imaging findings of thymic epithelial tumors classified according to the current World Health Organization (WHO) histologic classification and to determine useful findings in differentiating the main subtypes. Materials and methods: Sixty patients with thymic epithelial tumor who underwent both CT and MR imaging were reviewed retrospectively. All cases were classified according to the 2004 WHO classification. The following findings were assessed in each case on both CT and MRI: size of tumor, contour, perimeter of capsule; homogeneity, presence of septum, hemorrhage, necrotic or cystic component within tumor; presence of mediastinal lymphadenopathy, pleural effusion, and great vessel invasion. These imaging characteristics of 30 low-risk thymomas (4 type A, 12 type AB, and 14 type B1), 18 high-risk thymomas (11 type B2 and seven type B3), and 12 thymic carcinomas on CT and MR imaging were compared using the chi-square test. Comparison between CT and MR findings was performed by using McNemar test. Results: On both CT and MR imaging, thymic carcinomas were more likely to have irregular contours (P < .001), necrotic or cystic component (P < .05), heterogeneous contrast-enhancement (P < .05), lymphadenopathy (P < .0001), and great vessel invasion (P < .001) than low-risk and high-risk thymomas. On MR imaging, the findings of almost complete capsule, septum, and homogenous enhancement were more commonly seen in low-risk thymomas than high-risk thymomas and thymic carcinomas (P < .05). MR imaging was superior to CT in the depiction of capsule, septum, or hemorrhage within tumor (all comparison, P < .05). Conclusion: The presence of irregular contour, necrotic or cystic component, heterogeneous enhancement, lymphadenopathy, and great vessel invasion on CT or MR imaging are strongly suggestive of thymic carcinomas. On MR imaging, the findings of contour, capsule, septum, and homogenous enhancement are helpful in

    Single-agent chemotherapy has been the standard of treatment for nonmetastatic and metastatic low-risk gestational trophoblastic neoplasia (GTN). However, it is estimated that approximately 12% to 32% of patients given single-agent therapy will require a change of chemotherapy regimen because of drug resistance and/or intolerable toxicity. The Section of Trophoblastic Diseases of the Philippine General Hospital started using the combination of etoposide-actinomycin (EA) as salvage chemotherapy in the early 2000s. This study was carried out to describe the local experience with this salvage chemotherapy. This is a retrospective descriptive study aimed to analyze the efficacy and safety of the EA regimen as salvage treatment for the management of nonmetastatic and low-risk metastatic GTN. Records of the Section of Trophoblastic Diseases of the Philippine General Hospital from January 1, 2002 to June 30, 2014 were reviewed to identify all patients who had a diagnosis of nonmetastatic and metastatic low-risk GTN. Primary remission rate and toxicity profile of all patients who received the EA regimen as salvage treatment were determined. During the study period, a total of 67 cycles of the EA regimen were administered to 15 patients as salvage chemotherapy. Patients received a median of 4 cycles of EA, attaining normal serum beta human chorionic gonadotropin after 2 to 3 cycles. Thirteen of the 15 patients achieved complete remission with the EA regimen, giving a remission rate of 87%. The major toxicity that the patients experienced was myelosuppression. Grade 1/2 anemia was addressed by blood transfusion. Grade 3 neutropenia/myelosuppression was addressed by the administration of granulocyte colony-stimulating factor. Alopecia was seen in all of the patients. One patient experienced dermatitis with accompanying myelosuppression. The EA regimen was efficacious and well tolerated for the treatment of refractory nonmetastatic and low- risk metastatic GTN.

    To analyze the correlation between pathological data found in radical prostatectomy and previously performed biopsy in patients at low risk prostate cancer. A descriptive, cross-sectional study was conducted to assess the characteristics of radical prostatectomies performed in our center from January 2012 to November 2014. The inclusion criteria were patients with low-risk disease (cT1c-T2a, PSA≤10ng/mL and Gleason score≤6). We excluded patients who had fewer than 8 cores in the biopsy, an unspecified number of affected cores, rectal examinations not reported in the medical history or biopsies performed in another center. Of the 184 patients who underwent prostatectomy during this period, 87 met the inclusion criteria, and 26 of these had<3 affected cores and PSA density≤.15 (very low risk). In the entire sample, the percentage of undergrading (Gleason score≥7) and extracapsular invasion (pT3) was 18.4% (95% CI 10.3-27.6) and 10.35% (95% CI 4.6-17.2), respectively. The percentage of positive margins was 21.8% (95% CI 12.6-29.9). In the very low-risk group, we found no cases of extracapsular invasion and only 1 case of undergrading (Gleason 7 [3+4]), representing 3.8% of the total (95% CI 0-12.5). Predictors of no correlation (stage≥pT3a or undergrading) were the initial risk group, volume, PSA density and affected cores. Prostate volume, PSA density, the number of affected cores and the patient's initial risk group influence the poor pathological prognosis in the radical prostatectomy specimen (extracapsular invasion and Gleason score≥7).

  2. Debunking the claim that abstinence is usually healthier for smokers than switching to a low-risk alternative, and other observations about anti-tobacco-harm-reduction arguments

    Directory of Open Access Journals (Sweden)

    Phillips Carl V

    2009-11-01

    Full Text Available Abstract Nicotine is so desirable to many people that when they are given only the options of consuming nicotine by smoking, with its high health costs, and not consuming nicotine at all, many opt for the former. Few smokers realize that there is a third choice: non-combustion nicotine sources, such as smokeless tobacco, electronic cigarettes, or pharmaceutical nicotine, which eliminate almost all the risk while still allowing consumption of nicotine. Widespread dissemination of misleading health claims is used to prevent smokers from learning about this lifesaving option, and to discourage opinion leaders from telling smokers the truth. One common misleading claim is a risk-risk comparison that has not before been quantified: A smoker who would have eventually quit nicotine entirely, but learns the truth about low-risk alternatives, might switch to an alternative instead of quitting entirely, and thus might suffer a net increase in health risk. While this has mathematical face validity, a simple calculation of the tradeoff -- switching to lifelong low-risk nicotine use versus continuing to smoke until quitting -- shows that such net health costs are extremely unlikely and of trivial maximum magnitude. In particular, for the average smoker, smoking for just one more month before quitting causes greater health risk than switching to a low-risk nicotine source and never quitting it. Thus, discouraging a smoker, even one who would have quit entirely, from switching to a low-risk alternative is almost certainly more likely to kill him than it is to save him. Similarly, a strategy of waiting for better anti-smoking tools to be developed, rather than encouraging immediate tobacco harm reduction using current options, kills more smokers every month than it could possibly ever save.

    Though the incidence of CNS relapse in acute promyelocytic leukemia (AML-M3 FAB classification) has increased following the advent of all-trans retinoic acid (ATRA), still CNS relapse accounts for only 2–3% of all relapses in AML-M3 trated with standard ATRA plus chemotherapy regimen. We report a case of low risk AML-M3 treated with standard therapy, developing CNS relapse while on maintenance therapy with ATRA + 6-mercaptopurine (6-MP) + methotrexate (MTX).

    The pilot study aimed to explore the effects of an educational intervention on patients' foot self-care knowledge, self-efficacy, and behaviors in adult patients with type 2 diabetes at low risk for foot ulceration. The intervention consisted of three sessions and was given over a 3-week period. A total of 70 eligible consenting participants were recruited for this pilot study. Fifty-six participants completed the study. The outcomes were assessed at pretest, following the first two sessions, and 3-month follow-up. The findings indicated that the foot self-care educational intervention was effective in improving foot self-care knowledge, self-efficacy and behaviors in adult patients with type 2 diabetes at low risk for foot ulceration. The findings support the effects of the intervention. Future research should evaluate its efficacy using a randomized clinical trial design, and a large sample of patients with type 2 diabetes at low risk for foot ulcerations. © The Author(s) 2013.

    Objective: This prospective study evaluated the recurrence rate in low-risk patients with papillary thyroid cancer (PTC) who presented slightly elevated thyroglobulin (Tg) after thyroidectomy and who did not undergo ablation with {sup 131}I. Subjects and methods: The study included 53 low-risk patients (non aggressive histology; pT1b-3, cN0pNx, M0) with slightly elevated Tg after thyroidectomy (> 1 ng/mL, but ≤ 5 ng/mL after levothyroxine withdrawal or ≤ 2 ng/mL after recombinant human TSH). Results: The time of follow-up ranged from 36 to 96 months. Lymph node metastases were detected in only one patient (1.9%). Fifty-two patients continued to present negative neck ultrasound. None of these patients without apparent disease presented an increase in Tg. Conclusions: Low-risk patients with PTC who present slightly elevated Tg after thyroidectomy do not require ablation with {sup 131}I. (author)

  7. KIT Mutation and Loss of 14q May Be Sufficient for the Development of Clinically Symptomatic Very Low-Risk GIST.

    Full Text Available The aim of this study was to determine the minimal set of genetic alterations required for the development of a very low risk clinically symptomatic gastro-intestinal stromal tumour within the stomach wall. We studied the genome of a very low-risk gastric gastro-intestinal stromal tumour by whole-genome sequencing, comparative genomic hybridisation and methylation profiling. The studied tumour harboured two typical genomic lesions: loss of the long arm of chromosome 14 and an activating mutation in exon 11 of KIT. Besides these genetic lesions, only two point mutations that may affect tumour progression were identified: A frame-shift deletion in RNF146 and a missense mutation in a zinc finger of ZNF407. Whilst the frameshift deletion in RNF146 seemed to be restricted to this particular tumour, a similar yet germline mutation in ZNF407 was found in a panel of 52 gastro-intestinal stromal tumours from different anatomical sites and different categories. Germline polymorphisms in the mitotic checkpoint proteins Aurora kinase A and BUB1 kinase B may have furthered tumour growth. The epigenetic profile of the tumour matches that of other KIT-mutant tumours. We have identified mutations in three genes and loss of the long arm of chromosome 14 as the so far minimal set of genetic abnormalities sufficient for the development of a very low risk clinically symptomatic gastric stromal tumour.

    As the threshold of stroke risk for initiating oral anticoagulants is lowered after the introduction of the nonvitamin K antagonist oral anticoagulants, the focus of stroke prevention in patients with nonvalvular atrial fibrillation has shifted away from predicting high-risk patients toward initially identifying patients with a truly low risk of ischemic stroke, who do not need antithrombotic therapy. We tested the predictive ability of the congestive heart failure, hypertension, age ≥75, diabetes mellitus, prior stroke or transient ischemic attack (doubled; CHADS 2 ), congestive heart failure, hypertension, age ≥75 (doubled), diabetes mellitus, prior stroke or transient ischemic attack (doubled), vascular disease, age 65 to 74, female (CHA 2 DS 2 -VASc), and Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) risk stratification schemes in oral anticoagulants naive patients with atrial fibrillation in a Korean nationwide sample cohort. From January 2002 to December 2008, a total of 5855 oral anticoagulant naive patients with nonvalvular atrial fibrillation aged ≥20 years were enrolled from Korea National Health Insurance Service-Sample Cohort database and were followed-up until December 2013. At baseline, the proportions categorized as low risk using CHADS 2 , CHA 2 DS 2 -VASc, and ATRIA risk stratification schemes were 1049 (17.9%), 860 (14.7%), and 3280 (56.0%), respectively. During follow-up, the low-risk category using CHADS 2 , CHA 2 DS 2 -VASc, and ATRIA scores was retained in 811 (13.9%), 667 (11.4%), and 2729 (46.6%) patients, respectively. Rates of ischemic stroke (100 person-years) in the low risk categories of CHADS 2 , CHA 2 DS 2 -VASc, and ATRIA scores were 0.42, 0.26, and 1.43, respectively. CHA 2 DS 2 -VASc had the best sensitivity (98.8% versus 85.7% in CHADS 2 and 74.8% in ATRIA) and negative predictive value (98.8% versus 95.3% for CHADS 2 and 93.7% for ATRIA) for the prediction of stroke incidence and was best for the

    Home-based self-collection of specimens for urogenital and anorectal chlamydia testing has been proven feasible and acceptable. We studied the efficiency of chlamydia home collection kits for young low-risk persons to optimize care at the Amsterdam sexually transmitted infection (STI) clinic. Low-risk heterosexual persons under 25 years submitting an appointment request online were offered 3 different ways of chlamydia testing: (1) receiving a home collection kit, (2) coming to the clinic without, or (3) with sexual health counseling. The collection kit was sent to the client by surface mail and was used to self-collect a vaginal swab or urine sample (men). This sample was sent back to the laboratory for testing and the results could be retrieved online. Testing for gonorrhea, syphilis, and human immunodeficiency virus was indicated after testing chlamydia-positive. Between September 2012 until July 2013, from 1804 online requests, 1451 (80%) opted for the home collection kit, 321 (18%) preferred an appointment at the clinic without, and 32 (2%) with sexual health counseling. Of the requested home collection kits, 88% were returned. Chlamydia was diagnosed in 6.0% of the clients receiving a home collection kit, and none of the chlamydia-positive clients tested positive for other STI. Home collection is the preferred method for most young low-risk heterosexual clients who seek STI care. With a high compliance to collect and return the samples, home collection can be used as a tool to increase efficiency and dedicate STI clinic workers efforts to those at highest risk.

    The aim of this analysis was to compare the biochemical no evidence of disease (bNED) rates in low-risk prostate cancer patients treated at two centers of excellence using different approaches: seed brachytherapy (BT) and external beam radiotherapy (EBRT). Materials and methods: A total of 919 low-risk prostate cancer patients, treated from 1998-2008, were identified in the two databases. In Utrecht, 667 patients received I-125 BT applying a dose of 144 Gy. In Vienna, 252 patients were treated with EBRT, applying a local dose of 70 Gy in 82 patients and 74 Gy in 170 patients. bNED rates (Phoenix definition) were assessed. Results: The median follow-up was 46 months (range 1-148 months). The 5-year actuarial bNED rates were 94% for BT patients and 88% for EBRT patients (p = 0.002) - 84% for patients receiving 70 Gy and 91% for patients receiving 74 Gy, respectively. In the univariate analysis, patients receiving 70 Gy showed significantly worse outcome compared to BT (p = 0.001) and a difference close to significance compared to 74 Gy (p = 0.06). In the multivariate analysis including tumor stage, Gleason score, initial PSA, hormonal therapy, and dose, patients receiving 70 Gy EBRT showed significantly worse bNED rates compared to BT patients. Conclusion: Low-risk prostate cancer patients receiving 74 Gy by EBRT show comparable biochemical control rates to patients receiving seed brachytherapy, whereas patients receiving 70 Gy show significantly worse outcome.

  11. Gateway Effects: Why the Cited Evidence Does Not Support Their Existence for Low-Risk Tobacco Products (and What Evidence Would).

    It is often claimed that low-risk drugs still create harm because of "gateway effects", in which they cause the use of a high-risk alternative. Such claims are popular among opponents of tobacco harm reduction, claiming that low-risk tobacco products (e.g., e-cigarettes, smokeless tobacco) cause people to start smoking, sometimes backed by empirical studies that ostensibly support the claim. However, these studies consistently ignore the obvious alternative causal pathways, particularly that observed associations might represent causation in the opposite direction (smoking causes people to seek low-risk alternatives) or confounding (the same individual characteristics increase the chance of using any tobacco product). Due to these complications, any useful analysis must deal with simultaneity and confounding by common cause. In practice, existing analyses seem almost as if they were designed to provide teaching examples about drawing simplistic and unsupported causal conclusions from observed associations. The present analysis examines what evidence and research strategies would be needed to empirically detect such a gateway effect, if there were one, explaining key methodological concepts including causation and confounding, examining the logic of the claim, identifying potentially useful data, and debunking common fallacies on both sides of the argument, as well as presenting an extended example of proper empirical testing. The analysis demonstrates that none of the empirical studies to date that are purported to show a gateway effect from tobacco harm reduction products actually does so. The observations and approaches can be generalized to other cases where observed association of individual characteristics in cross-sectional data could result from any of several causal relationships.

    Full Text Available Introduction: The increasing rate of patient exposure to radiation from computerized tomography (CT raises questions about appropriateness of utilization. There is no current standard to employ informed consent for CT (ICCT. Our study assessed the relationship between informed consent and CT utilization in emergency department (ED patients. Methods: An observational multiphase before-after cohort study was completed from 4/2010-5/2011. We assessed CT utilization before and after (Time I/ Time II the implementation of an informed consent protocol. Adult patients were included if they presented with symptoms of abdominal/pelvic pathology or completed ED CT. We excluded patients with pregnancy, trauma, or altered mental status. Data on history, exam, diagnostics, and disposition were collected via standard abstraction tool. We generated a multivariate logistic model via stepwise regression, to assess CT utilization across risk groups. Logistic models, stratified by risk, were generated to include study phase and a propensity score that controlled for potential confounders of CT utilization. Results: 7,684 patients met inclusion criteria. In PHASE 2, there was a 24% (95% CI [10-36%] reduction in CT utilization in the low-risk patient group (p<0.002. ICCT did not affect CT utilization in the high-risk group (p=0.16. In low-risk patients, the propensity score was significant (p<0.001. There were no adverse events reported during the study period. Conclusion: The implementation of ICCT was associated with reduced CT utilization in low-risk ED patients. ICCT has the potential to increase informed, shared decision making with patients, as well as to reduce the risks and cost associated with CT.

    Full Text Available Introduction: Acute coronary syndrome accounts for more than 15% of the chest pains. Recently, Hess et al. developed North American Chest Pain Rule (NACPR to identify very low-risk patients who can be safely discharged from emergency department (ED. The present study aimed to validate this rule in EDs of two academic hospitals.Methods: A prospective diagnostic accuracy study was conducted on consecutive patients 24 years of age and older presenting to the ED with the chief complaint of acute chest pain, during March 2013 to June 2013. Chest pain characteristics, cardiac history, electrocardiogram findings, and cardiac biomarker measurement of patients were collected and screening performance characteristics of NACPR with 95% confidence interval were calculated using SPSS 21.Results: From 400 eligible patients with completed follow up, 69 (17.25 % developed myocardial infarction, 121 (30.25% underwent coronary revascularization, and 4 (2% died because of cardiac or unidentifiable causes. By using NACPR, 34 (8.50% of all the patients could be considered very low- risk and discharged after a brief ED assessment. Among these patients, none developed above-mentioned adverse outcomes within 30 days. Sensitivity, specificity, positive prediction value, and negative prediction value of the rule were 100% (95% CI: 87.35 - 100.00, 45.35 (95% CI: 40.19 - 50.61, 14.52 (95% CI: 10.40 – 19.85, and 100 (95% CI: 97.18 - 100.00, respectively.Conclusions: The present multicenter study showed that NACPR is a good screening tool for early discharge of patients with very low-risk chest pain from ED.

    General movement (GM) assessment is a well-established tool to predict cerebral palsy in high-risk infants. Little is known on the predictive value of GM assessment in low-risk populations. To assess the predictive value of GM quality in early infancy for the development of the clinically relevant form of minor neurological dysfunction (complex MND) and behavioral problems at preschool age. Prospective cohort study. A total of 216 members of the prospective Groningen Assisted Reproductive Techniques (ART) cohort study were included in this study. ART did not affect neurodevelopmental outcome of these relatively low-risk infants born to subfertile parents. GM quality was determined at 2 weeks and 3 months. At 18 months and 4 years, the Hempel neurological examination was used to assess MND. At 4 years, parents completed the Child Behavior Checklist; this resulted in the total problem score (TPS), internalizing problem score (IPS), and externalizing problem score (EPS). Predictive values of definitely (DA) and mildly (MA) abnormal GMs were calculated. DA GMs at 2 weeks were associated with complex MND at 18 months and atypical TPS and IPS at 4 years (all pvalue of DA GMs at 2 weeks were rather low (13%-60%); specificity and negative predictive value were excellent (92%-99%). DA GMs at 3 months occurred too infrequently to calculate prediction. MA GMs were not associated with outcome. GM quality as a single predictor for complex MND and behavioral problems at preschool age has limited clinical value in children at low risk for developmental disorders.

    The dietary intake allowed during the latent and active phases of labour varies between Canadian hospitals. Our objective was to document current restrictions on oral and parenteral intake for low-risk labouring women in hospitals across Canada. We carried out a cross-sectional study of 118 Canadian hospitals that have specialized birthing centres. Information on dietary protocols for low-risk women in labour was obtained from each hospital via a brief telephone interview with the head nurse of each birthing centre. Data were presented by stage of labour, both with and without epidural anaesthesia, and also by dextrose supplementation of intravenous fluids. If epidural anaesthesia was not used during the active phase of labour, oral intake was restricted to clear fluids and/or ice chips in 50.9% of surveyed hospitals and oral intake could include solid food in 38.1%. However, when epidural anaesthesia was used during the active phase of labour, oral intake was restricted to clear fluids and ice chips in 82.8% of surveyed hospitals, while oral intake could include solid food in 7.2%. Furthermore, in 77.5% of hospitals, not only was oral intake during active labour with epidural anaesthesia limited to clear fluids and/or ice chips, but in addition this restrictive diet was not supplemented with parenteral dextrose. The majority of low-risk pregnant women in Canadian hospitals are subjected to caloric restriction during the active phase of labour, especially when epidural anaesthesia is administered. Further studies on this subject are warranted because such pervasive practices may have important population effects on labouring women.

    Full Text Available Abstract Background Low-risk prostate cancer (PCa patients have excellent outcomes, with treatment modality often selected by perceived effects on quality of life. Acute urinary symptoms are common during external beam radiotherapy (EBRT, while chronic symptoms have been linked to urethral dose. Since most low-risk PCa occurs in the peripheral zone (PZ, we hypothesized that EBRT using urethral sparing intensity modulated radiation therapy (US-IMRT could improve urinary health-related quality of life (HRQOL while maintaining high rates of PCa control. Methods Patients with National Comprehensive Cancer Network (NCCN defined low-risk PCa with no visible lesion within 5 mm of the prostatic urethra on MRI were randomized to US-IMRT or standard (S- IMRT. Prescription dose was 75.6 Gy in 41 fractions to the PZ + 3–5 mm for US-IMRT and to the prostate + 3 mm for S-IMRT. For US-IMRT, mean proximal and distal urethral doses were limited to 65 Gy and 74 Gy, respectively. HRQOL was assessed using the Expanded Prostate Cancer Index (EPIC Quality of Life questionnaire. The primary endpoint was change in urinary HRQOL at 3 months. Results From June 2004 to November 2006, 16 patients were randomized, after which a futility analysis concluded that continued accrual was unlikely to demonstrate a difference in the primary endpoint. Mean change in EPIC urinary HRQOL at 3 months was −0.5 ± 11.2 in the US-IMRT arm and +3.9 ± 15.3 in the S-IMRT arm (p = 0.52. Median PSA nadir was higher in the US-IMRT arm (1.46 vs. 0.78, p = 0.05. At 4.7 years median follow-up, three US-IMRT and no S-IMRT patients experienced PSA failure (p = 0.06; HR 8.8, 95% CI 0.9–86. Two out of 3 patients with PSA failure had biopsy-proven local failure, both located contralateral to the original site of disease. Conclusions Compared with S-IMRT, US-IMRT failed to improve urinary HRQOL and resulted in higher PSA nadir and inferior biochemical

    Routine preoperative testing is discouraged before low-risk surgery because testing does not provide any beneficial effect in terms of patient outcome. However, few studies have assessed the utilization of hospital health care resources in terms of preoperative tests in a real-world setting. Here, we aimed to assess the prevalence and factors associated with preoperative blood tests before low-risk surgery in Japan. In this retrospective observational study, we used the nationwide insurance claims data of Japan. Patients who underwent low-risk surgeries between April 1, 2012, and March 31, 2016, were included. Our primary outcome was the receipt of any preoperative tests within 60 days before an index procedure: complete blood count, basic metabolic panel, coagulation tests, and liver function tests. We performed a descriptive analysis to estimate the proportions of preoperative blood tests, and examined the associations between patient-level and institutional-level factors and preoperative blood tests, using multilevel logistic regression analysis. Interinstitutional variation in the utilization of preoperative tests was summarized using the median odds ratio (OR). The study sample included 59,818 patients (mean [standard deviation] age, 44.0 [11.3] years; 33,574 [56.1%] women) from 9746 institutions. The overall proportion of each test was: complete blood count, 58.7%; metabolic panel, 47.8%; coagulation tests, 36.6%; and liver function tests, 48.5%. The proportion receiving any preoperative tests in the overall sample was 59.5%. Multilevel logistic regression analysis indicated that preoperative blood tests were associated with the Charlson comorbidity index score (score ≥3: adjusted OR, 4.21; 95% confidence interval [CI], 3.69-4.80), anticoagulant use (adjusted OR, 4.12; 95% CI, 2.35-7.22), type of anesthesia (general anesthesia: adjusted OR, 5.69; 95% CI, 4.85-6.68; regional anesthesia: adjusted OR, 3.76; 95% CI, 3.28-4.30), surgical setting (inpatient

    2011-08-01

    Full Text Available Abstract Background The visual system plays an important role in maintaining balance. As a person ages, gait becomes slower and stride becomes shorter, especially in dimly lighted environments. Falls risk has been associated with reduced speed and increased gait variability. Methods Twenty-four older adults (half identified at risk for falls experienced three lighting conditions: pathway illuminated by 1 general ceiling-mounted fixtures, 2 conventional plug-in night lights and 3 plug-in night lights supplemented by laser lines outlining the pathway. Gait measures were collected using the GAITRite© walkway system. Results Participants performed best under the general ceiling-mounted light system and worst under the night light alone. The pathway plus night lights increased gait velocity and reduced step length variability compared to the night lights alone in those at greater risk of falling. Conclusions Practically, when navigating in more challenging environments, such as in low-level ambient illumination, the addition of perceptual cues that define the horizontal walking plane can potentially reduce falls risks in older adults.

    We aimed to derive and validate a risk score that identifies adults with cerebrospinal fluid (CSF) pleocytosis and a negative CSF Gram stain at low risk for an urgent treatable cause. Patients with CSF pleocytosis and a negative CSF Gram stain were stratified into a prospective derivation (n = 193) and a retrospective validation (n = 567) cohort. Clinically related baseline characteristics were grouped into three composite variables, each independently associated with a set of predefined urgent treatable causes. We subsequently derived a risk score classifying patients into low (0 composite variables present) or high (≥ 1 composite variables present) risk for an urgent treatable cause. The sensitivity of the risk score was determined in the validation cohort and in a prospective case series of 214 adults with CSF-culture proven bacterial meningitis, CSF pleocytosis and a negative Gram stain. A total of 41 of 193 patients (21%) in the derivation cohort and 71 of 567 (13%) in the validation cohort had an urgent treatable cause. Sensitivity of the dichotomized risk score to detect an urgent treatable cause was 100.0% (95% CI 93.9-100.0%) in the validation cohort and 100.0% (95% CI 97.8-100.0%) in bacterial meningitis patients. The risk score can be used to identify adults with CSF pleocytosis and a negative CSF Gram stain at low risk for an urgent treatable cause. Copyright © 2013 The British Infection Association.

    Full Text Available Background:India contributes to 19% of the global maternal deaths. Good quality antenatal care can prevent maternal deaths by early detection of complications and maintaining maternal health. There are few studies documenting quality of antenatal care in India. This study aimed to document the antenatal services provided by nurse midwives to low-risk pregnant mothers from an urban population. Aims: The primary objective was to describe the quality of the antenatal care provided by nurse midwives of an urban health centre with regard to low-risk mothers. The secondary objective was to document the maternal and early neonatal outcomes of the enrolled mothers during the period of study. Methods: This prospective cohort study was done on 200 pregnant women who had antenatal care by nurse midwives between April 2014 and November 2014. The quality of care was assessed by a checklist adapted from World Health Organization (WHO. Results: We report that the quality of antenatal care for all domains was above 90% except for the health education domain, which was poor with regard to breastfeeding and family planning in the enrolled 200 pregnant women. Conclusion: Our study concluded that trained nurse midwives when regularly monitored, audited and linked with reliable referral facilities can deliver good quality antenatal care.

    AIMS: To evaluate the impact of umbilical and uterine artery Doppler in the second and third trimester on antenatal course, labor and delivery in a low-risk primigravid population. METHODS: Prospective recruitment of 1011 low-risk primigravidas with uterine and umbilical artery Doppler assessment at 22-24 weeks and 36 weeks. All mothers and infants were reviewed postnatally with a retrospective analysis of ultrasound and clinical outcome data. RESULTS: Elevated uterine artery indices were associated with increased rates of threatened miscarriage, higher rates of pre-eclampsia (PET) and a higher incidence of fetal birth weight <2nd and 9th centile for gestation. Uterine artery pulsatility index (PI) >95th centile for gestation was associated with statistically higher rates of small-for-gestational age (SGA) infants. Elevated umbilical artery indices were associated with higher rates of induction of labor and a higher incidence of fetal birth weight infants <2nd and 9th centile for gestation. Umbilical artery PI >95th centile for gestation was associated with statistically higher rates of SGA infants. CONCLUSION: Elevated uterine and umbilical artery indices are associated with higher rates of maternal and fetal disease.

    At 2.2 percent in 2012, the home birth rate in Iceland is the highest in the Nordic countries and has been rising rapidly in the new millennium. The objective of this study was to compare the outcomes of planned home births and planned hospital births in comparable low-risk groups in Iceland. The study is a retrospective cohort study comparing the total population of 307 planned home births in Iceland in 2005-2009 to a matched 1:3 sample of 921 planned hospital births. Regression analysis, adjusted for confounding variables, was performed for the primary outcome variables. The rate of oxytocin augmentation, epidural analgesia, and postpartum hemorrhage was significantly lower when labor started as a planned home birth. Differences in the rates of other primary outcome variables were not significant. The home birth group had lower rates of operative birth and obstetric anal sphincter injury. The rate of 5-minute Apgar score < 7 was the same in the home and hospital birth groups, but the home birth group had a higher rate of neonatal intensive care unit admission. Intervention and adverse outcome rates in both study groups, including transfer rates, were higher among primiparas than multiparas. Oxytocin augmentation, epidural analgesia, and postpartum hemorrhage rates were significantly interrelated. This study adds to the growing body of evidence that suggests that planned home birth for low-risk women is as safe as planned hospital birth. © 2015 Wiley Periodicals, Inc.

    To correlate BMI, lipidemic control, and statin therapy with PAD measured by ABI in low risk type 2 diabetics. A sample of 101 nonsmoking, asymptomatic type 2 diabetics (50 males, 51 females) with known glycemic (fasting blood sugar, postprandial blood sugar, glycosylated hemoglobin) and lipidemic (total cholesterol, lipoproteins, and triglycerides [TGAs]) control was taken. Vascular Doppler was used to derive ABI and PAD was defined as ABI control and prevalence of PAD 30%. There was insignificantly low ABI profile in patient having BMI ≥25, hyperlipidemia and absent statin therapy with odds ratio being highest for TGAs ≥150 (3.23) followed by BMI ≥25 (2.61), high-density lipoprotein ≤50 (1.61), low-density lipoprotein ≥100 (1.20), and disuse of statin (1.14) with significance only for BMI. We observed small, insignificant PAD risk by dyslipidemia or non-use of statins in low-risk ambulatory T2DM patients, not so by BMI. This suggests importance of good glycemic control, maintenance of optimum weight, and lifestyle modifications as primary prevention rather than opting for costly and inefficient secondary prevention.

    Overdiagnosis induced by prostate cancer screening makes necessary a better selection of candidate patients for prostate biopsy. The objective of our study is to assess the probability of having a high- or low-risk lesion that could require active surveillance (AS) after biopsies and a normal or abnormal examination, including transrectal and power Doppler ultrasonography (TRUS-PDS). Four hundred and twenty-nine consecutive patients with a PSA level risk of a biological recurrence and Dall'Era's criteria to assess possible AS. The TRUS-PDS was considered positive if one biopsy was positive in the same sextant as the suspect image. One hundred and seventy-seven out of 429 (41 %) T1c cancers were diagnosed; 131 out of 177 (74 %) could be qualified as low risk, and 119 out of 177 (67 %) could require AS. The TRUS-PDS was normal in 285 of 429 patients (66 %). With a normal TRUS-PDS, the probability of not having cancer with a high or intermediate risk was 96 % (negative predictive value). With an abnormal TRUS-PDS, the probability of having a positive biopsy was 59 %, and the probability of having a significant cancer was 30 %, according to the Dall'Era criteria. When TRUS-PDS was normal, these probabilities significantly decreased to 32 and 5 %, respectively ( p  risk of high- or intermediate-risk cancer.

    To determine the effect of prophylactic tranexamic acid (TA) on calculated and measured blood loss after vaginal delivery in women at low risk of postpartum haemorrhage. In this double-blind randomised controlled trial, 120 women with a singleton pregnancy were randomly allocated to receive either one gram intravenous TA or placebo in addition to 10 IU oxytocin after delivery of the fetus. Calculated blood loss was determined based on haematocrit before delivery and 12-24 h postdelivery. The quantity of blood loss was measured during two time periods: from delivery of the fetus to placental expulsion and from placental expulsion to the end of the second hour after childbirth. The mean (SD) calculated total blood loss (519 (320) vs 659 (402) mL, P = 0.036) and measured blood loss from placental delivery to 2 h postpartum (69 (39) vs 108 (53) mL, P  1000 mL was lower in the TA group (7% vs 18%, P = 0.048). Prophylactic TA reduces blood loss after vaginal delivery in women with a low risk of postpartum haemorrhage. The prophylactic use of TA may reduce blood loss complications and enhance maternal health. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Abstract Background Patients with chemotherapy-related neutropenia and fever are usually hospitalized and treated on empirical intravenous broad-spectrum antibiotic regimens. Early diagnosis of sepsis in children with febrile neutropenia remains difficult due to non-specific clinical and laboratory signs of infection. We aimed to analyze whether IL-6 and IL-8 could define a group of patients at low risk of septicemia. Methods A prospective study was performed to assess the potential value of IL-6, IL-8 and C-reactive protein serum levels to predict severe bacterial infection or bacteremia in febrile neutropenic children with cancer during chemotherapy. Statistical test used: Friedman test, Wilcoxon-Test, Kruskal-Wallis H test, Mann-Whitney U-Test and Receiver Operating Characteristics. Results The analysis of cytokine levels measured at the onset of fever indicated that IL-6 and IL-8 are useful to define a possible group of patients with low risk of sepsis. In predicting bacteremia or severe bacterial infection, IL-6 was the best predictor with the optimum IL-6 cut-off level of 42 pg/ml showing a high sensitivity (90% and specificity (85%. Conclusion These findings may have clinical implications for risk-based antimicrobial treatment strategies.

    Post-operative thyroglobulin (Tg) levels can predict the likelihood of residual cancer, including distant metastases, thereby influencing postsurgical treatment strategies even in patients with low-risk disease. Circulating anti-thyroglobulin antibodies (anti-Tg Abs) interfere with Tg measurement preventing this clinical use. It is not known if the presence of anti-Tg Abs predicts metastatic disease on post-therapy scan in patients with low-risk disease or if they should influence the use or dose of I-131 therapy. In the present study, we compare post-therapy scans in low-risk patients with and without anti-Tg Abs. This is a single-institution retrospective study. The study population (Group A) included all patients with low-risk differentiated thyroid cancer (DTC) who underwent total thyroidectomy and RAI between 1/1/2006 to 9/11/2015 with intrathyroidal T1-T2, Nx, N0 or N1a (≤5 nodes all measuring, when reported, scan results were compared by Chi-square test with 86% negative post therapy scan frequency in group A and 92% in group B without evidence of a difference (p = 0.45). In patients with low-risk DTC, anti-Tg Abs did not significantly predict metastatic disease on post-therapy scan. If confirmed, these data suggest that the presence of anti-Tg Abs alone should not influence initial therapy in patients with low-risk DTC.

  13. Distinguishing Low-Risk Luminal A Breast Cancer Subtypes with Ki-67 and p53 Is More Predictive of Long-Term Survival.

    Full Text Available Overexpression of p53 is the most frequent genetic alteration in breast cancer. Recently, many studies have shown that the expression of mutant p53 differs for each subtype of breast cancer and is associated with different prognoses. In this study, we aimed to determine the suitable cut-off value to predict the clinical outcome of p53 overexpression and its usefulness as a prognostic factor in each subtype of breast cancer, especially in luminal A breast cancer. Approval was granted by the Institutional Review Board of Samsung Medical Center. We analyzed a total of 7,739 patients who were surgically treated for invasive breast cancer at Samsung Medical Center between Dec 1995 and Apr 2013. Luminal A subtype was defined as ER&PR + and HER2- and was further subclassified according to Ki-67 and p53 expression as follows: luminal A (Ki-67-,p53-, luminal A (Ki-67+, p53-, luminal A (Ki-67 -, p53+ and luminal A (Ki-67+, p53+. Low-risk luminal A subtype was defined as negative for both Ki-67 and p53 (luminal A [ki-67-, p53-], and others subtypes were considered to be high-risk luminal A breast cancer. A cut-off value of 10% for p53 was a good predictor of clinical outcome in all patients and luminal A breast cancer patients. The prognostic role of p53 overexpression for OS and DFS was only significant in luminal A subtype. The combination of p53 and Ki-67 has been shown to have the best predictive power as calculated by the area under curve (AUC, especially for long-term overall survival. In this study, we have shown that overexpression of p53 and Ki-67 could be used to discriminate low-risk luminal A subtype in breast cancer. Therefore, using the combination of p53 and Ki-67 expression in discriminating low-risk luminal A breast cancer may improve the prognostic power and provide the greatest clinical utility.

    This pilot study compared placental growth factor (PIGF) levels in populations with high versus low risk for cardiovascular disease. Previous experiments from our laboratory (Sundaresan et al. 2005, 2009) revealed that the angiogenic factor PIGF was up regulated in modeled microgravity conditions in human lymphocytes leading to possible atherogenesis and pathogenesis in microgravity. Since the findings came from microgravity analog experiments, there is a strong link to its usefulness in the microgravity field as a biomarker. It is important to understand, that these findings came from both studies on expression levels of this cardiovascular marker in human lymphocytes in microgravity ( in vitro microgravity analog), and a follow up gene expression study in hind limb suspended mice ( in vivo microgravity analog). The relevance is enhanced because in life on earth, PIGF is an inflammatory biomarker for cardiovascular disease. Studies on the levels of PIGF would help to reduce the risk and prevention of heart failures in astronauts. If we can use this marker to predict and reduce the risk of cardiac events in astronauts and pilots, it would significantly help aerospace medicine operations. The investigations here confirmed that in a cardiovascular stressed population such as coronary artery disease (CAD) and acute coronary syndrome (ACS) patients, PIGF could be overexpressed. We desired to re-evaluate this marker in patients with cardiovascular disease in our own study. PIGF is a marker of inflammation and a predictor of short-term and long-term adverse outcome in ACS. In addition, elevated PIGF levels may be associated with increased risk for CAD.PIGF levels were determined in thirty-one patients undergoing cardiovascular catheterization for reasons other than ACS and in thirty-three low-risk asymptomatic subjects. Additional data on traditional cardiovascular risk factors for both populations were also compiled and compared. We found that PIGF levels were

    The management of papillary thyroid carcinoma (PTC) in high-risk patients is well-standardized. However, this is not the case for low-risk patients. Filipinos show a high incidence of recurrence of thyroid cancer. Thus, the identification of risk factors for recurrence in this population could potentially identify individuals for whom radioactive iodine (RAI) therapy might be beneficial. We reviewed the medical records of adult Filipinos with low-risk PTC who underwent near-total or total thyroidectomy at the University of the Philippines-Philippine General Hospital. Multivariate logistic regression analysis was used to determine risk factors for recurrence. Recurrence was documented in 51/145 of patients (35.17%) included in this study. Possible risk factors such as age, sex, family history, smoking history, tumor size, multifocality, prophylactic lymph node dissection, initial thyroglobulin (Tg) level, initial anti-thyroglobulin (anti-Tg) antibody concentration, suppression of thyroid stimulating hormone production, and RAI therapy were analyzed. Multivariate analysis revealed that a tumor diameter 2 to 4 cm (odds ratio [OR], 9.17; 95% confidence interval [CI], 1.62 to 51.88; P=0.012), a tumor diameter >4 cm (OR, 16.46; 95% CI, 1.14 to 237.31; P=0.04), and a family history of PTC (OR, 67.27; 95% CI, 2.03 to 2228.96; P=0.018) were significant predictors of recurrence. In addition, RAI therapy (OR, 0.026; 95% CI, 0.01 to 0.023; P≤0.005), an initial Tg level ≤2 ng/mL (OR, 0.049; 95% CI, 0.01 to 0.23; P≤0.005), and an anti-Tg antibody level ≤50 U/mL (OR, 0.087; 95% CI, 0.011 to 0.67; P=0.019) were significant protective factors. A tumor diameter ≥2 cm and a family history of PTC are significant predictors of recurrence. RAI therapy and low initial titers of Tg and anti-Tg antibody are significant protective factors against disease recurrence among low-risk PTC patients.

    To evaluate long-term outcomes of active surveillance (AS) applied in low-risk prostate cancer patients, and the impact of re-biopsy results on the prediction of progression. In our clinic, patients who had undergone AS for low-risk localized prostate cancer between the years 2005-2013 were included in the study. Our AS criteria are Gleason score ≤6, prostate-specific antigen (PSA) level digital rectal examination (DRE) every 3 months within the first 2 years, than every 6 months. Control biopsies was performed one year later and once upon every 3 years to patients whose PSA levels and DREs were normal at follow-up visits. More than 2 tumor invaded cores or 50% tumor in one core, and Gleason score exceeding 6 points were accepted as indications for definitive treatment. Patients were divided into two groups by re-biopsy results and compared according to the time to progression. We have done multivariate regression analysis to predict prognosis by using data on age, PSA level, and detection of tumor in re-biopsy specimens. Patients' median age was 61 years and PSA level was 5 (2.7-9) ng/mL. Tumor was detected in 22 (34%) patients at re-biopsy and they underwent definitive treatment. Additionally tumor was detected in 9 patients, but active surveillance was maintained because their pathologic results met active surveillance criteria. Median follow time was 42 (24-117) months. Definitive treatment was performed in 9 (21%) patients. PSA recurrence was not detected in none of 9 patients during 38 months of follow up. Only the presence of tumor in re-biopsy specimens was found predictor of disease progression in multivariate analysis. We think that AS is safe method for low-risk localized prostate cancer patients, if it is performed in compliance with certain criteria and regular follow up, and early re-biopsy can be useful either during early period or long term follow-up.

    The incidence of papillary microcarcinoma (PMC) of the thyroid is rapidly increasing globally, making the management of PMC an important clinical issue. Excellent oncological outcomes of active surveillance for low-risk PMC have been reported previously. Here, unfavorable events following active surveillance and surgical treatment for PMC were studied. From February 2005 to August 2013, 2153 patients were diagnosed with low-risk PMC. Of these, 1179 patients chose active surveillance and 974 patients chose immediate surgery. The oncological outcomes and the incidences of unfavorable events of these groups were analyzed. In the active surveillance group, 94 patients underwent surgery for various reasons; tumor enlargement and the appearance of novel lymph node metastases were the reasons in 27 (2.3%) and six patients (0.5%), respectively. One of the patients with conversion to surgery had nodal recurrence, and five patients in the immediate surgery group had a recurrence in a cervical node or unresected thyroid lobe. All of these recurrences were successfully treated. None of the patients had distant metastases, and none died of the disease. The immediate surgery group had significantly higher incidences of transient vocal cord paralysis (VCP), transient hypoparathyroidism, and permanent hypoparathyroidism than the active-surveillance group did (4.1% vs. 0.6%, p < 0.0001; 16.7% vs. 2.8%, p < 0.0001; and 1.6% vs. 0.08%, p < 0.0001, respectively). Permanent VCP occurred only in two patients (0.2%) in the immediate surgery group. The proportion of patients on L-thyroxine for supplemental or thyrotropin (TSH)-suppressive purposes was significantly larger in the immediate surgery group than in the active surveillance group (66.1% vs. 20.7%, p < 0.0001). The immediate surgery group had significantly higher incidences of postsurgical hematoma and surgical scar in the neck compared with the active surveillance group (0.5% vs. 0%, p < 0.05; and 8.0% vs

    High dairy/milk intake has been associated with a low risk of type 2 diabetes observationally, but whether this represents a causal association is unknown. We tested the hypothesis that high milk intake is associated with a low risk of type 2 diabetes and of overweight-obesity, observationally and genetically. In 97,811 individuals from the Danish general population, we examined the risk of incident type 2 diabetes and of overweight-obesity by milk intake observationally and by LCT-13910 C/T genotype [polymorphism (rs4988235) upstream from the lactase (LCT) gene], where TT and TC genotypes are associated with lactase persistence and CC with nonpersistence. Observationally for any compared with no milk intake, the HR for type 2 diabetes was 1.10 (95% CI: 0.98, 1.24; P = 0.11), whereas the OR for overweight-obesity was 1.06 (1.02, 1.09; P = 0.002). Median milk intake was 5 glasses/wk (IQR: 0-10) for lactase TT/TC persistence and 3 (0-7) for CC nonpersistence. Genetically for lactase TT/TC persistence compared with CC nonpersistence, the OR was 0.96 (0.86, 1.08; P = 0.50) for type 2 diabetes and 1.06 (1.00, 1.12; P = 0.04) for overweight-obesity. In a stratified analysis for type 2 diabetes, corresponding values in those with and without milk intake were 0.88 (0.76, 1.03; P = 0.11) and 1.35 (1.07, 1.70; P = 0.01) (P-interaction: 0.002), whereas no gene-milk interaction on overweight-obesity was found. For a 1-glass/wk higher milk intake, the genetic risk ratio for type 2 diabetes was 0.99 (0.93, 1.06), and the corresponding observational risk was 1.01 (1.00, 1.01). For overweight-obesity, the corresponding values were 1.01 (1.00, 1.02) genetically and 1.00 (1.00, 1.01) observationally. High milk intake is not associated with a low risk of type 2 diabetes or overweight-obesity, observationally or genetically via lactase persistence. The higher risk of type 2 diabetes in lactase-persistent individuals without milk intake likely is explained by collider stratification

    Planned caesarean delivery (CD) frequency is increasing in many countries, and elective CD accounts for 50% of preventable causes of neonatal respiratory morbidity. The clearing of fluid in the lungs is important for the establishment of normal gas exchange with inspired air. A defect in this clearance can result in respiratory problems in neonate, but on the other hand patients waiting for the onset of spontaneous labour pain, the increase in emergency CD, together with severe mortality and morbidity are causes of concern and cause anxiety and distrust of obstetricians. In the current study, it was observed that foetal respiratory morbidity was reduced in the group with labour pain. The caesarean applied after the onset of labour pain could be a reason for the significant increase in foetal cord cortisol values in term low-risk neonates. A major advantage of this study was the inclusion of a low-risk patient group, and the increase in foetal cortisol secondary to pain in term neonates was shown objectively. Impact statement What is already known on this subject: The timing of CD is reported to be critical for neonatal morbidity, and elective CD accounts for 50% of preventable causes of neonatal respiratory morbidity. The clearing of fluid in the lungs is important for the establishment of normal gas exchange with inspired air. Cortisol secretion from the foetal adrenal gland is stimulated by stress. What do the results of this study add: Labour pain-related stress in the foetus might be a cause for elevated physiological cortisol, and secondary to that, lower respiratory morbidity. Caesarean delivery commenced after the onset of labour pain could be a reason for the significant increase in foetal cord cortisol values in term neonates. A major advantage of this study was the inclusion of a low-risk patient group, and the increase in foetal cortisol secondary to pain in term neonates was shown objectively. What are the implications of these findings for clinical

    This study was designed to track the developmental trajectory, during the first 24 months of life, of 335 low-risk infants later diagnosed with Autism Spectrum Disorder and identify early deviations observed in routine Well Care checkups. We compared their achievements to typically developing children and to children later diagnosed with non-autistic developmental impairments. The results show that in the first 6 months, the children with autism showed normal acquisition of milestones, whereas by 9 months of age they began to fail the language/communication, as well as motor items when compared to typical and delayed non-autistic children. Regular check-up visits may be useful in detecting early failure in achieving milestones, leading to earlier referral for further evaluation and treatment.

    Given the emphasis on early screening for ASD, it is crucial to examine the concordance between parent report and clinician observation of autism-related behaviors. Similar items were compared from the First Year Inventory (Baranek et al. First-Year Inventory (FYI) 2.0. University of North Carolina, Chapel Hill, 2003), a parent screener for ASD, and the ADOS-2 Toddler Module (Lord et al. 2013), a standardized ASD diagnostic tool. Measures were administered concurrently to 12-month-olds at high and low risk for ASD. Results suggest that clinicians and parents rated behaviors similarly. In addition, both informants rated high-risk infants as more impaired in several social-communication behaviors. Furthermore, the format of questions impacted agreement across observers. These findings have implications for the development of a new generation of screening instruments for ASD.

    Our objective was to examine the association between fetal growth in early pregnancy and risk of severe large-for-gestational-age (LGA) and macrosomia at birth in a low-risk population. Cohort study that included 68 771 women with non-anomalous singleton pregnancies, without history of diabetes or hypertension, based on an electronic database on pregnancies and deliveries in Stockholm-Gotland Region, Sweden, 2008-2014. We performed multivariable logistic regression to estimate the association between accelerated fetal growth occurring in the first through early second trimester as measured by ultrasound and LGA and macrosomia at birth. Restricted analyses were performed in the groups without gestational diabetes and with normal body mass index (18.5-24.9 kg/m 2 ). When adjusting for confounders, the odds of having a severely LGA or macrosomic infant were elevated in mothers with fetuses that were at least 7 days larger than expected as compared with mothers without age discrepancy at the second-trimester scan (adjusted odds ratio 1.80; 95% CI 1.23-2.64 and adjusted odds ratio 2.15; 95% CI 1.55-2.98, respectively). Additionally, mothers without gestational diabetes and mothers with normal weight had an elevated risk of having a severely LGA or macrosomic infant when the age discrepancy by second-trimester ultrasound was at least 7 days. In a low-risk population, ultrasound-estimated accelerated fetal growth in early pregnancy was associated with an increased risk of having a severely LGA or macrosomic infant. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available This preliminary study aimed to 1 determine changes in the salivary oxytocin (OT level during breast stimulation for promoting the spontaneous onset of labor in low-risk term pregnancies, and 2 clarify the feasibility of the breast stimulation intervention protocol in terms of practicality and acceptability.We used a single arm trial design. Sixteen low-risk pregnant women between 38 and 40 weeks of gestation with cephalic presentation participated. They performed breast stimulation for 3 days with an attendant midwife in a single maternity hospital. Each breast was stimulated for 15 minutes for a total of 1 hour per day. Saliva was collected 10 minutes before the intervention and 15, 30, 60, 75, and 90 minutes after the intervention, yielding 18 samples per woman.Among a total of 282 saliva samples from the 16 participants, OT level was measured in 142 samples (missing rate: 49.6%. The median OT level showed the highest values on day 3 of the breast stimulation, with a marked increase 30 min after the intervention. In the mixed models after multiple imputation for missing data, the OT level on the first day of intervention was significantly lower than that on the third day of intervention. Fatigue from breast stimulation decreased on subsequent days, and most of the women (75% felt no discomfort with the protocol. Uterine hyperstimulation was not observed.Following a 3-day breast stimulation protocol for spontaneous onset of labor, the mean OT level showed the highest values on day 3. The breast stimulation intervention protocol showed good feasibility in terms of practicality and acceptability among the pregnant women. Additional large-scale studies are warranted to confirm the protocol's effectiveness.

    Purpose: To analyze the effect of reduced-dose radiotherapy on local control in children with low-risk rhabdomyosarcoma (RMS) treated in the Children's Oncology Group D9602 study. Methods and Materials: Patients with low-risk RMS were nonrandomly assigned to receive radiotherapy doses dependent on the completeness of surgical resection of the primary tumor (clinical group) and the presence of involved regional lymph nodes. After resection, most patients with microscopic residual and uninvolved nodes received 36 Gy, those with involved nodes received 41.4 to 50.4 Gy, and those with orbital primary tumors received 45 Gy. All patients received vincristine and dactinomycin, with cyclophosphamide added for patient subsets with a higher risk of relapse in Intergroup Rhabdomyosarcoma Study Group III and IV studies. Results: Three hundred forty-two patients were eligible for analysis; 172 received radiotherapy as part of their treatment. The cumulative incidence of local/regional failure was 15% in patients with microscopic involved margins when cyclophosphamide was not part of the treatment regimen and 0% when cyclophosphamide was included. The cumulative incidence of local/regional failure was 14% in patients with orbital tumors. Protocol-specified omission of radiotherapy in girls with Group IIA vaginal tumors (n = 5) resulted in three failures for this group. Conclusions: In comparison with Intergroup Rhabdomyosarcoma Study Group III and IV results, reduced-dose radiotherapy does not compromise local control for patients with microscopic tumor after surgical resection or with orbital primary tumors when cyclophosphamide is added to the treatment program. Girls with unresected nonbladder genitourinary tumors require radiotherapy for postsurgical residual tumor for optimal local control to be achieved.

    The echolucency of the carotid intima-media is related to increased cardiovascular risk factor levels, morbidity, and mortality. The aim of this study was to assess the effect of statins on the echolucency of the common carotid intima-media in a low-risk population. Data from the Measuring Effects on Intima-Media Thickness: An Evaluation of Rosuvastatin study were used. Ultrasound images from the far walls of the left and right common carotid arteries were used for evaluation of the echolucency of the carotid intima-media, measured by grayscale median (GSM). Low GSM values reflect echolucent structures, whereas high values reflect echogenic structures. The primary end point was the difference in the annual rate of change in GSM between rosuvastatin and placebo. Two-year change in GSM did not significantly differ between rosuvastatin and placebo in the total population, with a mean difference in the rate of change in GSM of 1.13 (95% confidence interval, -1.00 to 3.25). The effect of rosuvastatin differed across quintiles of baseline GSM values (P for interaction = .01). In the lowest quintile (n = 175) (i.e., in those with the most echolucent intima-media), the difference in the rate of change in GSM between rosuvastatin and placebo was 4.18 (95% confidence interval, -0.23 to 8.58). Increases in GSM were significantly related to decreasing low-density lipoprotein cholesterol levels in the lowest quintile (β = 0.76; 95% confidence interval, 0.26 to 1.25). Treatment with rosuvastatin did not affect the echolucency of the arterial wall in all low-risk individuals. However, a potential effect of rosuvastatin on the echolucency of the common carotid intima-media is most likely to be found in individuals with echolucent arterial walls at baseline.

    There are mixed reports in the literature about obstetric intervention and maternal and neonatal outcomes for migrant women born in resource rich countries. The aim of this study was to compare the risk profile, rates of obstetric intervention and selected maternal and perinatal outcomes for low risk women born in Australia compared to those born overseas. A population-based descriptive study was undertaken in NSW of all singleton births recorded in the NSW Midwives Data Collection between 2000-2008 (n=691,738). Risk profile, obstetric intervention rates and selected maternal and perinatal outcomes were examined. Women born in Australia were slightly younger (30 vs 31 years), less likely to be primiparous (41% vs 43%), three times more likely to smoke (18% vs 6%) and more likely to give birth in a private hospital (26% vs 18%) compared to women not born in Australia. Among the seven most common migrant groups to Australia, women born in Lebanon were the youngest, least likely to be primiparous and least likely to give birth in a private hospital. Hypertension was lowest amongst Vietnamese women (3%) and gestational diabetes highest amongst women born in China (14%). The highest caesarean section (31%), instrumental birth rates (16%) and episiotomy rates (32%) were seen in Indian women, along with the highest rates of babies obstetric intervention rates and maternal and neonatal outcomes between Australian-born and women born overseas and these differences are seen overall and in low risk populations. The finding that Indian women (the leading migrant group to Australia) have the lowest normal birth rate and high rates of low birth weight babies is concerning, and attention needs to be focused on why there are disparities in outcomes and on effective models of care that might improve outcomes for this population.

    The goal of this study is to identify predictive factors in patients with a diagnosis of early-stage cervical cancer after simple hysterectomy in order to avoid a radical parametrectomy. A retrospective review was performed of all patients who underwent radical parametrectomy and bilateral pelvic lymphadenectomy at MD Anderson Cancer Center and at the Instituto de Cancerologia Las Americas in Medellin, Colombia from December 1999 to September 2017. We sought to determine the outcomes in patients diagnosed with low-risk factors (squamous, adenocarcinoma or adenosquamous lesions<2cm in size, and invading<10mm) undergoing radical parametrectomy and pelvic lymphadenectomy. A total of 30 patients were included in the study. The median age was 40.4years (range; 26-60) and median body mass index (BMI) was 26.4kg/m 2 (range; 17.7-40.0). A total 22 patients had tumors<1cm and 8 had tumors between 1 and 2cm. A total of 6 (33%) of 18 patients had evidence of lymph-vascular invasion (LVSI). No radical parametrectomy specimen had residual tumor, involvement of the parametrium, vaginal margin positivity, or lymph node metastasis. None of the patients received adjuvant therapy. After a median follow-up of 99months (range; 6-160) only one patient recurred. Radical parametrectomy may be avoided in patients with low-risk early-stage cervical cancer detected after a simple hysterectomy. Rates of residual disease (parametrial or vaginal) and the need for adjuvant treatments or recurrences are very low. Copyright © 2018 Elsevier Inc. All rights reserved.

  8. Preventing preterm birth with progesterone: costs and effects of screening low risk women with a singleton pregnancy for short cervical length, the Triple P study

    2011-10-01

    Full Text Available Abstract Background Women with a short cervical length in mid-trimester pregnancy have a higher risk of preterm birth and therefore a higher rate of neonatal mortality and morbidity. Progesterone can potentially decrease the number of preterm births and lower neonatal mortality and morbidity. Previous studies showed good results of progesterone in women with either a history of preterm birth or a short cervix. However, it is unknown whether screening for a short cervix and subsequent treatment in mid trimester pregnancy is effective in low risk women. Methods/Design We plan a combined screen and treat study among women with a singleton pregnancy without a previous preterm birth. In these women, we will measure cervical length at the standard anomaly scan performed between 18 and 22 weeks. Women with cervical length ≤ 30 mm at two independent measurements will be randomly allocated to receive either vaginal progesterone tablets or placebo between 22 and 34 weeks. The primary outcome of this trial is adverse neonatal condition, defined as a composite outcome of neonatal mortality and severe morbidity. Secondary outcomes are time to delivery, preterm birth rate before 32, 34 and 37 weeks, days of admission in neonatal intensive care unit, maternal morbidity, maternal admission days for preterm labour and costs. We will assess growth, physical condition and neurodevelopmental outcome of the children at two years of age. Discussion This study will provide evidence for the usefulness and cost-effectiveness of screening for short cervical length at the 18-22 weeks and subsequent progesterone treatment among low risk women.

    Currently, the French High Authority for Health does not recommend mass screening for prostate cancer (PCa), due to the risk of over-treatment, notably of low risk patients. Our study is intended to reflect the therapeutic attitudes for the management of patients classified as low risk of progression in French clinical centers. For all positive prostate biopsies performed during 2012 and 2013 in five French departments of urology, clinicopathological characteristics required to calculate the d'Amico risk group and the Cancer of the Prostate Risk Assessment (CAPRA) score were filled. Information on the first treatment of "low risk" patients was collected. A total of 1035 patients were included, with a median age at diagnosis of 66 years old. According to d'Amico and CAPRA classifications, 30.4% and 35.0% of patients were at low, 34.5% and 33.2% at intermediate, 35.1% and 31.8% at high risk. The diagnosis severity increased with age (P<0.0001). The main treatment for low risk patients was radical prostatectomy (41.6% and 42.0% for d'Amico and CAPRA, respectively), but active surveillance was the most frequent treatment if diagnosed after 75 years old. The management of low risk patients varied significantly between centers (P<0.0001), according to the therapeutic platforms available within the hospital. In absence of strong progression predictor, the management of low risk PCa remains based on center habits and local therapeutic platforms. New predictive markers, such as multiparametric MRI or molecular tests, are needed to guide rational management of low risk PCa. 4. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Minimal residual disease (MRD) is the most sensitive and specific predictor of relapse risk in children with acute lymphoblastic leukaemia (ALL) during remission. We assessed whether treatment intensity could be adjusted for children and young adults according to MRD risk stratification. Between Oct 1, 2003 and June 30, 2011, consecutive children and young adults (aged 1-25 years) with ALL from the UK and Ireland were recruited. Eligible patients were categorised into clinical standard, intermediate, and high risk groups on the basis of a combination of National Cancer Institute (NCI) criteria, cytogenetics, and early response to induction therapy, which was assessed by bone marrow blast counts taken at days 8 (NCI high-risk patients) and 15 (NCI standard-risk patients) after induction began. Clinical standard-risk and intermediate-risk patients were assessed for MRD. Those classified as MRD low risk (undetectable MRD at the end of induction [day 29] or detectable MRD at day 29 that became undetectable by week 11) were randomly assigned to receive one or two delayed intensification courses. Patients had received induction, consolidation, and interim maintenance therapy before they began delayed intensification. Delayed intensification consisted of pegylated asparaginase on day 4; vincristine, dexamethasone (alternate weeks), and doxorubicin for 3 weeks; and 4 weeks of cyclophosphamide and cytarabine. Computer randomisation was done with stratification by MRD result and balancing for sex, age, and white blood cell count at diagnosis by method of minimisation. Patients, clinicians, and data analysts were not masked to treatment allocation. The primary outcome was event-free survival (EFS), which was defined as time to relapse, secondary tumour, or death. Our aim was to rule out a 7% reduction in EFS in the group given one delayed intensification course relative to that given two delayed intensification courses. Analyses were by intention to treat.

    Sentinel lymph node (SLN) biopsy has been used to assess patients with papillary thyroid carcinoma (PTC). To achieve its full potential the rate of SLN identification must be as close to 100 percent as possible. In the present study we compared the combination of preoperative lymphoscintigraphy scanning by sulfur colloid labeled with 99 m Technetium, gamma-probe guided surgery, and methylene blue with methylene blue, alone, for sentinel node identification in younger women with unilateral low-risk PTC. From January 2004 to January 2007, 90 female patients, ages 23 to 44 (mean = 35), with unilateral low-risk PTC (T 1-2 N 0 M 0 ) were prospectively studied. Mean tumor size was 1.3 cm (range, 0.8-3.7 cm). All patients underwent unilateral modified neck dissection. Prior to surgery, patients had, by random assignment, identification and biopsy of SLNs by methylene blue, alone (Group 1), or by sulfur colloid labeled with 99 m Technetium, gamma-probe guided surgery and methylene blue (Group 2). In the methylene blue group, SLNs were identified in 39 of 45 patients (86.7%). Of the 39 patients, 28 (71.8%) had positive cervical lymph nodes (pN+), and 21 patients (53.8%) had pSLN+. In 7 of the 28 pN+ patients (25%), metastases were also detected in non-SLN, thus giving a false-negative rate (FNR of 38.9% (7/18), a negative predictive value (NPV) of 61.1% (11/18), and an accuracy of 82.1% (32/39). In the combined technique group, the identification rate (IR) of SLN was 100% (45/45). Of the 45 patients, 27 (60.0%) had pN+, 24 (53.3%) had pSLN+. There was a FNR of 14.3% (3/21), a NPV of 85.7% (18/21), and an accuracy of 93.3% (42/45). The combined techniques group was significantly superior to the methylene blue group in IR (p = 0.035). There were no significant differences between two groups in sensitivity, specificity, NPV, or accuracy. Location of pN+ (55 patients) in 84 patients was: level I and V, no patients; level II, 1 patient (1.2%); level III, 6 patients (7.2%); level

    Maternal age at delivery and cesarean section rates are increasing. In older women, the decision on delivery mode may be influenced by a reported increased risk of surgical interventions during labor and complications with increasing maternal age. We examined the association between maternal age and adverse outcomes in low-risk primiparous women, and the risk of adverse outcomes by delivery modes, both planned and performed (elective and emergency cesarean section, operative vaginal delivery, and unassisted vaginal delivery) in women aged ≥ 35 years. A population-based registry study was conducted using data from the Medical Birth Registry of Norway and Statistics Norway including 169,583 low-risk primiparas with singleton, cephalic labors at ≥ 37 weeks during 1999 - 2009. Outcomes studied were obstetric blood loss, maternal transfer to intensive care units, 5-min Apgar score, and neonatal complications. We adjusted for potential confounders using relative risk models and multinomial logistic regression. Most adverse outcomes increased with increasing maternal age. However, the increase in absolute risks was low, except for moderate obstetric blood loss and transfer to the neonatal intensive care unit (NICU). Operative deliveries increased with increasing maternal age and in women aged ≥ 35 years, the risk of maternal complications in operative delivery increased. Neonatal adverse outcomes increased mainly in emergency operative deliveries. Moderate blood loss was three times more likely in elective and emergency cesarean section than in unassisted vaginal delivery, and twice as likely in operative vaginal delivery. Low Apgar score and neonatal complications occurred two to three times more often in emergency operative deliveries than in unassisted vaginal delivery. However, comparing outcomes after elective cesarean section and planned vaginal delivery, only moderate blood loss (higher in elective cesarean section), neonatal transfer to

    Full Text Available BACKGROUND Meconium-stained amniotic fluid has been considered as sign of foetal distress in presentations other than breech and is associated with poor foetal outcome, but others consider meconium passage by foetus as physiological phenomenon and procedures of environmental hazards to foetus before birth. MATERIALS AND METHODS 200 women with meconium-stained amniotic fluid in labour, all low-risk pregnancies were included in our study from September 2010 to August 2012 admitted in our department. For uniformity of results, cases with obstetric and medical complications were excluded. The cases were divided into three groups depending upon grades of meconium staining as thin, moderate and thick. Foetal monitoring, uterine contractions and Apgar score, birth weight, resuscitation of baby noted. All babies were followed up to first week of neonatal life. RESULTS Of 200 cases, 147 had caesarean delivery 73.5% and 53 had vaginal delivery 26.5%. The incidence of LSCS was found to be maximum in the thick MSAF group 54.5%, 14% in moderate and 5% in this MSAF group. In moderate MSAF group, 2.17% had <7, 1 minute Apgar. In thick MSAF group, 3.33% had <7 Apgar; in thin MSAF group, 11.76% had <7 Apgar at 1 minute. The p value was 0.094 in all grades of MSAF, the 5 min. Apgar’s were more than 7. The occurrence of complications in the baby did not depend on the mode of delivery. The p value was 0.58, which was insignificant. The ‘p value of association of CTG abnormality and foetal morbidity was significant <0.001. The association of grades of meconium and foetal morbidity, the p value was 0.337, which was insignificant. There was no perinatal mortality in our study. CONCLUSION The incidence of low-risk pregnancies with MSAF in our study was 4.5%. There was increased tendency for LSCS in the MSAF. The foetal morbidity depends on the reactivity to CTG not on grades of MSAF. Therefore, close intrapartum monitoring has to be done in such cases and LSCS done

    Immigrants have higher risks for some adverse obstetric outcomes. Furthermore, refugees are reported to be the most vulnerable group. This study compared obstetric outcomes between immigrant women originating from conflict-zone countries and ethnic Norwegians who gave birth in a low-risk setting. This was a population-based study linking the Medical Birth Registry of Norway to Statistics Norway. The study included the first registered birth during the study period of women from Somalia (n = 278), Iraq (n = 166), Afghanistan (n = 71), and Kosovo (n = 67) and ethnic Norwegians (n = 6826) at Baerum Hospital from 2006-2010. Background characteristics and obstetric outcomes of each immigrant group were compared with ethnic Norwegians with respect to proportions and risks calculated by logistic regression models. In total, 7408 women and their births were analyzed. Women from Somalia were most at risk for adverse obstetric outcomes. Compared with ethnic Norwegians, they had increased odds ratios (OR) for emergency cesarean section (OR 1.81, CI 1.17-2.80), postterm birth (OR 1.93, CI 1.29-2.90), meconium-stained liquor (OR 2.39, CI 1.76-3.25), and having a small-for-gestational-age infant (OR 3.97, CI 2.73-5.77). They had a reduced OR for having epidural analgesia (OR 0.40, CI 0.28-0.56) and a large-for-gestational-age infant (OR 0.32, CI 0.16-0.64). Women from Iraq and Afghanistan had increased risk of having a small-for-gestational-age infant with OR of 2.21 (CI 1.36-3.60) and 2.77 (CI 1.42-5.39), respectively. Iraqi women also had reduced odds ratio of having a large-for-gestational-age infant (OR 0.35, CI 0.15-0.83). Women from Kosovo did not differ from ethnic Norwegians in any of the outcomes we tested. Even in our low-risk maternity ward, women originating from Somalia were at the greatest risk for adverse obstetric outcomes in the compared groups. We could not find the same risk among the other immigrant women, also originating from conflict-zone countries

    Given the costs of delivering care for men with prostate cancer remain poorly described, this article reports the results of time-driven activity-based costing (TDABC) for competing treatments of low-risk prostate cancer. Process maps were developed for each phase of care from the initial urologic visit through 12 years of follow-up for robotic-assisted laparoscopic prostatectomy (RALP), cryotherapy, high-dose rate (HDR) and low-dose rate (LDR) brachytherapy, intensity-modulated radiation therapy (IMRT), stereotactic body radiation therapy (SBRT), and active surveillance (AS). The last modality incorporated both traditional transrectal ultrasound (TRUS) biopsy and multiparametric-MRI/TRUS fusion biopsy. The costs of materials, equipment, personnel, and space were calculated per unit of time and based on the relative proportion of capacity used. TDABC for each treatment was defined as the sum of its resources. Substantial cost variation was observed at 5 years, with costs ranging from $7,298 for AS to $23,565 for IMRT, and they remained consistent through 12 years of follow-up. LDR brachytherapy ($8,978) was notably cheaper than HDR brachytherapy ($11,448), and SBRT ($11,665) was notably cheaper than IMRT, with the cost savings attributable to shorter procedure times and fewer visits required for treatment. Both equipment costs and an inpatient stay ($2,306) contributed to the high cost of RALP ($16,946). Cryotherapy ($11,215) was more costly than LDR brachytherapy, largely because of increased single-use equipment costs ($6,292 vs $1,921). AS reached cost equivalence with LDR brachytherapy after 7 years of follow-up. The use of TDABC is feasible for analyzing cancer services and provides insights into cost-reduction tactics in an era focused on emphasizing value. By detailing all steps from diagnosis and treatment through 12 years of follow-up for low-risk prostate cancer, this study has demonstrated significant cost variation between competing treatments. © 2015

    The frequency of ovarian cancers in Japan has increased; however, doubts have been raised concerning the mechanism by which high-grade serous adenocarcinomas (HGSCs) arise. Conventionally, HGSC is thought to originate from the ovarian surface epithelium or epithelial inclusion cyst. However, recent data indicate that HGSCs may in fact develop from precursor lesions in the fallopian tube, including epithelia with a p53 signature, serous tubal intraepithelial carcinomas (STICs), secretory cell outgrowths (SCOUTs), and tubal intraepithelial lesions in transition (TILT). Here, we determined the frequency of these fallopian tube precursors in surgically excised samples from 123 patients with benign pelvic diseases. We identified 12 cases with a p53 signature (9.7%), 26 with observable SCOUTs (21.1%), and 4 with TILT (3.2%), but no STIC cases. Although the lifetime risk for developing ovarian cancer is only around 1.4% for women without germ-line mutations, it is important to evaluate the presence of precursor lesions to understand HGSC pathogenesis better. Taken together, salpingectomy appears to be an option for women who are past their childbearing age and plan to undergo elective pelvic surgery. To our knowledge, this is the first study to investigate the presence of these specific precursors post-salpingectomy in low-risk patients. © 2016 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

    To determine women's perceptions of breast cancer risk and thresholds for desiring biopsy when considering BI-RADS 3 and 4A scenarios and recommendations, respectively. Women presenting for screening mammography from five geographically diverse medical centers were surveyed. Demographic information and baseline anxiety were queried. Participants were presented with scenarios of short-term imaging follow-up recommendations (ie, BI-RADS 3) and biopsy recommendations (ie, BI-RADS 4A) for low-risk mammographic abnormalities and asked to estimate their breast cancer risk for each scenario. Participants reported the threshold (ie, likelihood of cancer) where they would feel comfortable undergoing short-term imaging follow-up and biopsy and their anticipated regret for choosing short-term follow-up versus biopsy. Analysis of 2,747 surveys showed that participants estimated breast cancer risk of 32.8% for a BI-RADS 3 and 41.1% for a BI-RADS 4A scenarios are significantly greater rates than clinically established rates (risk associated with both BI-RADS 3 and 4A scenarios and desire very low biopsy thresholds. Greater anticipated regret and less relief and confidence was reported with the choice to undergo short-term imaging follow-up compared with biopsy. Copyright © 2018 American College of Radiology.

    Absolute value of the functional data of gated myocardial perfusion SPECT is necessary to determine that individual patient is normal or not. Tc-99m MIBI gated myocardial perfusion SPECT was performed using emory cardiac tool box program. All patients (M:F=15:36, age 64{+-}10 yrs) showed normal myocardial perfusion. The patients with following characteristics were excluded; previous angina or MI, ECG change with Q wave or ST-T change, diabetes mellitus, hypercholesterolemia, typical chest pain and hypertension. In all patients, myocardial mass is 117{+-}23 g in stress gated SPECT, 106{+-}22 g in stress ungated SPECT and 102{+-}21 g in rest ungated SPECT. EDV is 90{+-}28 ml, ESV 26{+-}20 ml, SV 66{+-}21 ml, EF 73{+-}10 % and TID 1.06{+-}0.14. Myocardial mass in rest ungated SPECT is significantly different between men and women (p=0.025). Myocardial mass is significantly different between stress gated SPECT and stress ungated SPECT (p=0.000), and between stress ungated SPECT and rest ungated SPECT (p=0.003). We provide normal value of functional parameters to determine the abnormality of individual patients in patients with low risk of coronary artery disease.

    We investigated the nuclear import of low risk HPV11 E7 protein using 1) transfection assays in HeLa cells with EGFP fusion plasmids containing 11E7 and its domains and 2) nuclear import assays in digitonin-permeabilized HeLa cells with GST fusion proteins containing 11E7 and its domains. The EGFP-11E7 and EGFP-11cE7 39-98 localized mostly to the nucleus. The GST-11E7 and GST-11cE7 39-98 were imported into the nuclei in the presence of either Ran-GDP or RanG19V-GTP mutant and in the absence of nuclear import receptors. This suggests that 11E7 enters the nucleus via a Ran-dependent pathway, independent of nuclear import receptors, mediated by a nuclear localization signal located in its C-terminal domain (cNLS). This cNLS contains the zinc binding domain consisting of two copies of Cys-X-X-Cys motif. Mutagenesis of Cys residues in these motifs changed the localization of the EGFP-11cE7/-11E7 mutants to cytoplasmic, suggesting that the zinc binding domain is essential for nuclear localization of 11E7.

    2012-07-01

    Our objective was to compare Ponderal index (PI) with birth weight centiles as predictors of perinatal morbidity and to determine which best reflects the presence of placental disease. We prospectively recruited 1,011 low-risk primigravidas and calculated PI and birth weight centiles following delivery. Perinatal morbidity was defined as: pre-term birth (PTB); fetal acidosis; an Apgar score <7 at 5 min or neonatal resuscitation. Placental disease was defined as chronic uteroplacental insufficiency (CUPI); villous dysmaturity; infection or vascular pathology. Ponderal index was statistically reduced (25.33 vs 27.79 p =0.001) and the incidence of infant birth weight <9th centile was statistically higher (11.1% vs 5.1%; p =0.004) in cases with PTB and in CUPI (26.23 vs 27.84; p =0.001 and 28.2.1% vs 10.4%; p =0.002). Both PI and infant birth weight centile <9th centile for gestational age correlate with PTB, however overall, both are poor predictors of neonatal and placental disease.

    To report the prevalence and incidence of low-risk human papillomavirus infection (LR-HPV) and anogenital warts (AGW) among women living with HIV (WLHIV) in Burkina Faso (BF) and South Africa (SA), and to explore HIV-related factors associated with these outcomes. We enrolled 1238 WLHIV (BF = 615; SA = 623) aged 25-50 years and followed them at three time points (6, 12 and 16 months) after enrolment. Presence of AGW was assessed during gynaecological examination. Cervico-vaginal swabs for enrolment and month 16 follow-up visits were tested for HPV infection by Inno-LiPA® genotyping. Logistic regression was used to assess risk factors for prevalent infection or AGW. Cox regression was used to assess risk factors for incident AGW. Women in SA were more likely than those in BF to have prevalent LR-HPV infection (BF: 27.1% vs. SA: 40.9%; p500 cells/μL). Duration of ART and HIV plasma viral load were not associated with any LR-HPV infection or AGW outcomes. LR-HPV infection and AGW are common in WLHIV in sub-Saharan Africa. Type-specific HPV vaccines and effective ART with immunological reconstitution could reduce the burden of AGW in this population.

    2017-06-01

    Background and aims The aim of this paper is to examine the evidence and arguments in favor of prevention paradox (PP) logic in the context of problem gambling. Evidence from recent studies of gambling and the distribution of harm across lower and higher risk gamblers is reviewed to examine the contention that the absolute burden of harm is greater in low-risk (LR) gamblers than the problem gamblers. Methods The review examines a number of methodological and conceptual concerns about existing evidence in support of the PP. Results The principal problems identified include the misclassification of LR gamblers; the use of binary scoring method that understates the frequency of harms in high-risk populations; a tendency to confuse behavior and harm; and the use of potentially overly inclusive definitions of harm with low thresholds of severity. Discussion and conclusions This paper makes a number of recommendations for enhancement of this area of research, including the use of clear definitions of harm and LR behavior and a greater focus on harm with material impacts on people's quality of life.

    We evaluated the efficacy of attractive toxic sugar baits (ATSB) in the laboratory and field with the low-risk active ingredient dinotefuran against mosquito populations. Preliminary laboratory assays indicated that dinotefuran in solution with the sugar baits was ingested and resulted in high mortality of female Culex quinquefasciatus Say and Aedes aegypti Linnaeus. Field studies demonstrated >70% reduction of mosquito populations at 3 wk post-ATSB application. Nontarget feeding of seven insect orders-Hymenoptera, Lepidoptera, Coleoptera, Diptera, Hemiptera, Orthoptera, and Neuroptera-was evaluated in the field after application of attractive sugar baits (ASB) on vegetation by dissecting the guts and searching for food dye with a dissecting microscope. Nontargets were found stained with ASB 0.9% of the time when the application was applied on green nonflowering vegetation. Only two families were significantly impacted by the ASB application: Culicidae (mosquitoes) and Chironomidae (nonbiting midges) of the order Diptera. Pollinators of the other insect orders were not significantly impacted. No mortality was observed in the laboratory studies with predatory nontargets, wolf spiders or ground beetles, after feeding for 3 d on mosquitoes engorged on ATSB applied to vegetation. Overall, this novel control strategy had little impact on nontarget organisms, including pollinators and beneficial insects, and was effective at controlling mosquito populations, further supporting the development of ATSB for commercial use.

    Intermittent assessment of renal artery flow velocity waveforms during the early stages of pregnancy may help in predicting changes in amniotic fluid dynamics. The current study sought to determine the relation of renal artery and umbilical artery flow velocity waveforms with normal pregnancies and pregnancies complicated by either polyhydramnios or oligohydramnios. Renal and umbilical artery Doppler values were evaluated at 22, 28 and 34 weeks' gestation in 300 low-risk pregnant women with singleton pregnancies. Pulsatility index (PI) and resistance index (RI) were recorded and the amniotic fluid volume was evaluated. Three groups were formed according to the amniotic fluid volume at birth. Group I consisted of 264 pregnant women with normal amniotic fluid, group II included 30 pregnant women with oligohydramnios and group III included six pregnant women with polyhydramnios. Doppler parameters were compared between the groups and within each group according to gestational age. Renal artery PI values were higher in group II than group I at 22 weeks, 28 weeks and 34 weeks. The PI value at 28 weeks' gestation was statistically significant (P = 0.011). At 28 weeks' gestation, group II also had higher umbilical artery PI and RI values than group I. An increase in renal artery PI develops in early pregnancy before the development of oligohydramnios. In pregnancies developing polyhydramnios, renal artery PI was lower; however, our study included a small number of women with polyhydramnios. © 2014 The Authors.

    This population-based study compares obstetric outcomes of first- and second-generation Pakistani immigrants and ethnic Norwegians who gave birth at the low-risk maternity ward in Baerum Hospital in Norway from 2006 to 2013. We hypothesized that second-generation Pakistani immigrants are more similar to the ethnic Norwegians because of increased acculturation. Outcome measures were labor onset, epidural analgesia, labor dystocia, episiotomy, vaginal/operative delivery, postpartum hemorrhage, preterm birth, birth weight, transfer to a neonatal intensive care unit, and neonatal jaundice. Compared to first-generation Pakistani immigrants, the second-generation reported more health issues before pregnancy, and they had a higher proportion of preterm births compared to Norwegians. Newborns of first-generation immigrants were more often transferred to a neonatal intensive care compared to Norwegian newborns. Few intergenerational differences in the obstetric outcomes were found between the two generations. A high prevalence of consanguinity in second-generation immigrants suggests the maintenance of a traditional Pakistani marriage pattern.

    Active surveillance (AS) is a well-recognized strategy to reduce the risk of overtreatment in men with low-risk prostate cancer. No data on this approach are available from Austria. The Qualitätspartnerschaft Urologie (QuapU) developed an online database for patients managed with AS in Austria. Principal inclusion/exclusion criteria corresponded to those of the S3 prostate cancer guideline of German urologists: prostate-specific antigen (PSA) 4-10 ng/ml: 85%). The prostate volume averaged 39 ml. The mean time under AS was 17.5 months (12 months: 40%). The AS adherence at 12 months was 85% and at 24 months 76%. To date, a total of 23 patients (17.6%) stopped AS. The most frequent reasons for discontinuing AS were patient wish for active treatment (43.5%) and PSA progression (30.4%). A histological progression was rarely seen (6.1%) and the control biopsy rate was low (19.8%). This study is the first description of AS in Austria and documents the feasibility of an online registry for AS. The data confirm the international experience with this approach with acceptable adherence rates.

    We determined the efficiency of a screening protocol based on coronary calcium scores (CCS) compared with exercise testing in patients with suspected coronary artery disease (CAD), a normal ECG and troponin levels. Three-hundred-and-four patients were enrolled in a screening protocol including CCS by electron beam computed tomography (Agatston score), and exercise testing. Decision-making was based on CCS. When CCS{>=}400, coronary angiography (CAG) was recommended. When CCS<10, patients were discharged. Exercise tests were graded as positive, negative or nondiagnostic. The combined endpoint was defined as coronary event or obstructive CAD at CAG. During 12{+-}4 months, CCS{>=}400, 10-399 and <10 were found in 42, 103 and 159 patients and the combined endpoint occurred in 24 (57%), 14 (14%) and 0 patients (0%), respectively. In 22 patients (7%), myocardial perfusion scintigraphy was performed instead of exercise testing due to the inability to perform an exercise test. A positive, nondiagnostic and negative exercise test result was found in 37, 76 and 191 patients, and the combined endpoint occurred in 11 (30%), 15 (20%) and 12 patients (6%), respectively. Receiver-operator characteristics analysis showed that the area under the curve of 0.89 (95% CI: 0.85-0.93) for CCS was superior to 0.69 (95% CI: 0.61-0.78) for exercise testing (P<0.0001). In conclusion, measurement of CCS is an appropriate initial screening test in a well-defined low-risk population with suspected CAD. (orig.)

    The natural history and optimal management of serous tubal intraepithelial carcinoma (STIC), regardless of BRCA status, is unknown. We report the follow-up findings of a series of incidental fallopian tube high-grade serous carcinomas (HGSCs) and STICs identified in women at low risk for hereditary breast and ovarian cancer (HBOC), undergoing surgery for other indications. Cases of incidental STIC and HGSC were identified from 2008. Patients with known BRCA1 or BRCA2 mutations, or a family history of ovarian or breast cancer before the diagnosis of STIC or HGSC were excluded. A retrospective chart review was conducted to obtain clinical data. Eighteen cases were identified with a median follow-up of 25 months (range, 4-88 months). Twelve of 18 patients had a diagnosis of STIC with no associated invasive HGSC and 6 had STIC associated with other invasive malignancies. Completion staging surgery was performed on 7 of the 18 patients, including 5 of 12 in which there was STIC only identified on primary surgery; 3 cases were upstaged from STIC only to HGSC based on the staging surgery. Recurrence of HGSC occurred in 2 of the 18 patients. BRCA testing was performed on 3 patients, 1 of whom tested positive for a pathogenic BRCA1 mutation. Our study suggests that completion staging surgery for incidental STICs in non-BRCA patients may be considered. These patients should be offered hereditary testing. The Pelvic-Ovarian cancer INTerception (POINT) Project is an international registry set up to add to our understanding of STICs.

    Full Text Available ABSTRACT Purpose We investigated the association between National Institute of Health category IV prostatitis and prostate-specific antigen levels in patients with low-risk localized prostate cancer. Materials and Methods The data of 440 patients who had undergone prostate biopsies due to high PSA levels and suspicious digital rectal examination findings were reviewed retrospectively. The patients were divided into two groups based on the presence of accompanying NIH IV prostatitis. The exclusion criteria were as follows: Gleason score>6, PSA level>20ng/mL, >2 positive cores, >50% cancerous tissue per biopsy, urinary tract infection, urological interventions at least 1 week previously (cystoscopy, urethral catheterization, or similar procedure, history of prostate biopsy, and history of androgen or 5-alpha reductase use. All patient's age, total PSA and free PSA levels, ratio of free to total PSA, PSA density and prostate volume were recorded. Results In total, 101 patients were included in the study. Histopathological examination revealed only PCa in 78 (77.2% patients and PCa+NIH IV prostatitis in 23 (22.7% patients. The median total PSA level was 7.4 (3.5–20.0 ng/mL in the PCa+NIH IV prostatitis group and 6.5 (0.6–20.0 ng/mL in the PCa group (p=0.67. The PSA level was≤10ng/mL in 60 (76.9% patients in the PCa group and in 16 (69.6% patients in the PCa+NIH IV prostatitis group (p=0.32. Conclusions Our study showed no statistically significant difference in PSA levels between patients with and without NIH IV prostatitis accompanying PCa.

    Full Text Available Abstract Background The SINS trial (Controlled Clinical Trials ISRCTN48755084; Eudract No. 2004-004506-24 is a randomised controlled trial evaluating long term success of excisional surgery vs. imiquimod 5% cream for low risk nodular and superficial basal cell carcinoma (BCC. The trial included a discrete choice experiment questionnaire to explore patient preferences of a cream versus surgery for the treatment of their skin cancer. Methods The self-completed questionnaire was administered at baseline to 183 participants, measuring patients’ strength of preferences when choosing either alternative ‘surgery’ or ‘imiquimod cream’ instead of a fixed ‘current situation’ option (of surgical excision as standard practice in UK. The treatments were described according to: cost, chance of complete clearance, side effects and appearance. Participants had to choose between various scenarios. Analysis was performed using a mixed logit model, which took into account the impact of previous BCC treatment and sample preference variability. Results The analysis showed that respondents preferred ‘imiquimod cream’ to their ‘current situation’ or ‘surgery’, regardless of previous experience of BCC symptoms and treatment. Respondents were more likely to be worried about their cosmetic outcomes and side effects they might experience over and above their chance of clearance and cost. Those with no experience of surgery (compared with experience valued more the choice of ‘imiquimod cream’ (£1013 vs £781. All treatment characteristics were significant determinants of treatment choice, and there was significant variability in the population preferences for all of them. Conclusions Patients with BCC valued more ‘imiquimod cream’ than alternative ‘surgery’ options, and all treatment characteristics were important for their choice of care. Understanding how people with a BCC value alternative interventions may better inform the

    Overexpression of CXC chemokine receptor 4 (CXCR4+) is a poor prognostic factor in adult acute myeloid leukemia (AML); however, its prognostic significance in pediatric AML is unclear. This retrospective study examined the prognostic significance of CXCR4+ in pediatric AML patients enrolled in the Japanese Pediatric Leukemia/Lymphoma Study Group AML-05 study. In the total cohort (n = 248), no significant differences were observed between CXCR4+ patients (n = 81) and CXCR4- patients (n = 167) in terms of 3-year overall survival (OS) (69.4% vs. 75.2%, P = 0.44). However, there was a significant difference in 3-year OS between CXCR4+ and CXCR4- patients in the low-risk (LR) group (n = 93; 79.2% vs. 98.3%, P = 0.007). CXCR4+ patients in the t(8;21) AML without KIT mutation group had a significantly worse 3-year OS than CXCR4- patients (n = 44; 76.1% vs. 100.0%, P = 0.01). Multivariate Cox regression analysis identified CXCR4+ as a poor prognostic factor for OS in LR AML patients (hazard ratio, 11.47; P = 0.01). Consistent with the data for survival analysis, CXCR4+ patients in the t(8;21) AML group had a higher incidence of splenomegaly than CXCR4- patients (25.9% vs. 5.9%, P = 0.03). These results suggest that CXCR4+ is a poor prognostic factor for LR patients, particularly t(8;21) patients without KIT mutation. The poor outcome was only applicable to OS, not relapse-free survival (RFS); thus, CXCR4+ may be associated with a poor prognosis after recurrence. Intensive therapy, including administration of CXCR4 antagonists, may be promising for pediatric AML patients with LR. © 2016 Wiley Periodicals, Inc.

    Contrast-enhanced spectral mammography (CESM) is a reliable problem solving tool in the work-up of women recalled from breast cancer screening. We evaluated additional findings caused by CESM alone and outweighed them against the disadvantages of this technique. From December 2012 to December 2015, all women recalled from screening who underwent CESM were considered for this study. Radiation exposure and number of adverse contrast reactions were analysed. An experienced breast radiologist reviewed all exams and identified cases with lesions detected by CESM alone and scored their conspicuity. From these cases, data on breast density and final diagnosis were collected. For malignant cases, tumour grade and receptor characteristics were also collected. During this study, 839 women underwent CESM after a screening recall, in which five minor adverse contrast reactions were observed. Median radiation dose per exam was 6.0mGy (0.9-23.4mGy). Seventy CESM-only lesions were detected in 65 patients. Of these 70 lesions, 54.3% proved to be malignant, most commonly invasive ductal carcinomas. The remaining CESM-only lesions were benign, predominantly fibroadenomas. No complications were observed during biopsy of these lesions. Retrospectively, the majority of the lesions were either occult or a 'minimal sign' on low-energy CESM images or the screening mammogram. Using CESM as a work-up tool for women recalled from screening carries low risk for the patient, while additionally detected tumour foci might hold important clinical implications which need to be further studied in large, randomized controlled trials.

    The SINS trial (Controlled Clinical Trials ISRCTN48755084; Eudract No. 2004-004506-24) is a randomised controlled trial evaluating long term success of excisional surgery vs. imiquimod 5% cream for low risk nodular and superficial basal cell carcinoma (BCC). The trial included a discrete choice experiment questionnaire to explore patient preferences of a cream versus surgery for the treatment of their skin cancer. The self-completed questionnaire was administered at baseline to 183 participants, measuring patients' strength of preferences when choosing either alternative 'surgery' or 'imiquimod cream' instead of a fixed 'current situation' option (of surgical excision as standard practice in UK). The treatments were described according to: cost, chance of complete clearance, side effects and appearance. Participants had to choose between various scenarios. Analysis was performed using a mixed logit model, which took into account the impact of previous BCC treatment and sample preference variability. The analysis showed that respondents preferred 'imiquimod cream' to their 'current situation' or 'surgery', regardless of previous experience of BCC symptoms and treatment. Respondents were more likely to be worried about their cosmetic outcomes and side effects they might experience over and above their chance of clearance and cost. Those with no experience of surgery (compared with experience) valued more the choice of 'imiquimod cream' (£1013 vs £781). All treatment characteristics were significant determinants of treatment choice, and there was significant variability in the population preferences for all of them. Patients with BCC valued more 'imiquimod cream' than alternative 'surgery' options, and all treatment characteristics were important for their choice of care. Understanding how people with a BCC value alternative interventions may better inform the development of health care interventions.

    Single Cell Network Profiling (SCNP) is a multiparametric flow cytometry-based assay that quantifiably and simultaneously measures changes in intracellular signaling proteins in response to in vitro extracellular modulators at the single cell level. Myelodysplastic syndrome (MDS) is a heterogeneous clonal disorder of hematopoietic stem cells that occurs in elderly subjects and is characterized by dysplasia and ineffective hematopoiesis. The functional responsiveness of MDS bone marrow (BM) hematopoietic cells, including functionally distinct myeloid and erythroid precursor subsets, to hematopoietic growth factors (HGF) and the relationship of modulated signaling to disease characteristics is poorly understood. SCNP was used first to examine the effects of age on erythropoietin (EPO) and granulocyte colony stimulating factor (GCSF)-induced signaling in myeloid, nucleated red blood cells (nRBC), and CD34 expressing cell subsets in healthy BM (n = 15). SCNP was then used to map functional signaling profiles in low risk (LR) MDS (n = 7) for comparison to signaling in samples from healthy donors and to probe signaling associations within clinically defined subgroups. In healthy BM samples, signaling responses to HGF were quite homogeneous (i.e., tightly regulated) with age-dependent effects observed in response to EPO but not to GCSF. Despite the relatively small number of samples assayed in the study, LR MDS could be classified into distinct subgroups based on both cell subset frequency and signaling profiles. As a correlate of underlying genetic abnormalities, signal transduction analyses may provide a functional and potentially clinically relevant classification of MDS. Further evaluation in a larger cohort is warranted. © 2013 Clinical Cytometry Society.

    Recent reports have suggested that day-care experience initiated prior to 12 months of age is associated with increased proportions of infants whose attachment to mother is classified as "insecure-avoidant." However, reviewers have questioned the generality of these findings, noting that samples in which associations between early day-care experience and avoidant attachment patterns have been reported come from high-risk populations, and/or that the infants' day-care settings may not have been of high quality. In the present study, effects of maternal absences on infant-mother attachment quality were assessed in a low-risk, middle-class sample (N = 110). In all instances, substitute care had been initiated at least 4 months prior to the infant's first birthday and was provided in the infant's home by a person unrelated to the baby. Infants were assessed using the Ainsworth Strange Situation when they were 12-13 months of age. Analyses indicated that a significantly greater proportion of infants whose mothers worked outside the home (N = 54) were assigned to the category "insecure-avoidant" as compared to infants whose mothers remained in the home (N = 56) throughout the first year of life. Analyses of demographic and psychological data available for the sample indicated that this relation is dependent upon maternal parity (primi- vs. multiparous mother). The association between attachment quality and work status was significant only for firstborn children of full-time working mothers. The results are interpreted as evidence that the repeated daily separations experienced by infants whose mothers are working full-time constitute a "risk" factor for the development of "insecure-avoidant" infant-mother attachments.

    This study aimed to detect the correlation between human papillomavirus (HPV) and spontaneous preterm labor in Egyptian women and its association to the human papilloma viral load and MPP2 gene expression. We performed an observational comparative case-control study in Department of Obstetric and Gynecology, Mansoura University Hospitals over women presented with spontaneous preterm labor, besides females admitted for giving birth at full term to detect conserved sequence in HPV-L1 gene (GP5/GP6) followed by genotype detection of high- and low-risk HPVs with quantification of the viral load and the MMP2 gene expression using real-time polymerase chain reaction (PCR). The prevalence of HPV was 18.1% in preterm females, but only 4% in full-term women (p value = 0.019*). Twenty percent were PCR positive for HPV 16 and 40% for HPV 18 whereas none of the control was positive for any of the studied high-risk genotypes. Thirty percent were PCR positive for HPV 6 and 10% were positive for HPV 11. MMP2 gene expression was significantly higher in preterm than full term. Human papilloma viral load was found to be positively correlated to the rate of MMP2 expression and the gestational age was significantly related to the viral load and the rate of expression of MMP2 gene. Human pabilloma virus especially high-risk genotypes was correlated to spontaneous preterm labor in Egyptian females through increasing early expression of MMP2 gene. The time of occurrence of preterm labor was affected by the viral load and so the rate of expression of MMP2 gene.

    β-thalassemia is an autosomal recessive blood disorder caused by gene mutations that affect all aspects of β-globin production. In majority of Asian countries including India, the frequency of β-thalassemia is closely intertwined with social, cultural, and religious issues of the respective country. Several national level screening programs imparted education regarding β-thalassemia, but follow-up evaluation revealed that education was not effective. It has been hypothesized that the beliefs and attitudes, carrier screening, and education among "high risk communities" will have far-reaching implications towards β-thalassemia prevention in the country. The present study is aimed to investigate attitudes, intention, and behavior of β-thalassemia high- and low-risk ethnic groups towards carrier screening and education. A structured questionnaire on knowledge, attitude, and practice regarding β-thalassemia was administered on 926 individuals belong to Arora, a high-risk ethnic group for β-thalassemia (347 rural (AR) and 202 urban (AU)) and 377 cosmopolitan commoners (CC) aged above 18 years of both sexes. To understand the relationship between various questions, Pearson's correlation test and factor analysis was performed. The responses were further categorized into the theory of planned behavior (TPB) constructs with the measures of the main constructs reported as a mean. Various dimensions of knowledge, attitude, and practice reveal that the urban groups (AU and CC) are better aware of the disease "β-thalassemia" than the rural group (AR) who witness suffering at close quarters. The AR group is more positive for preventive measures than the urban groups. Significant correlations and factor analysis show "intentions" for premarital and prenatal screening highly loaded as outcome behaviors. The Ajzen's "Theory of planned behavior" support that the "intention" and "perceived behavior control" are better predictors of "outcome behavior" compared to "attitude

    Mature T cell lymphoma has been noted for poor prognosis when compared with B cell lymphoma, even in the pre-rituximab era. To confirm this difference, a retrospective cohort study was conducted. One hundred-and nineteen patients with mature T cell lymphoma and 568 patients with diffuse large B cell lymphoma (DLBCL) who did not receive rituximab as first induction were studied. Overall survival (OS) was worse for patients with international prognostic index (IPI) scores indicating low-risk mature T cell lymphoma than for those with DLBCL (3-year OS 87 % vs. 58 %, P = 0.001), but not in other risk groups. Prognosis of mature T cell lymphoma was significantly poorer in the IPI low-risk group, as compared with DLBCL.

    Gestational trophoblastic neoplasia (GTN) is a rare tumor, and its genomic constitution is different from the maternal genome because of its gestational origin. Methotrexate (MTX) is a standard chemotherapeutic agent for low-risk GTN. An association between polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene and MTX treatment outcome has been reported in various diseases. Thus, we examined the association between clinical outcome and MTHFR polymorphisms in both tumor and blood DNA of low-risk GTN patients. MTHFR C677T (rs1801133) and A1298C (rs1801131) were genotyped using high-resolution melting assays in 62 Japanese low-risk GTN patients and in 52 antecedent molar tissues. We compared the genotypes of MTHFR polymorphisms with the clinical outcome of 5-day MTX treatment. Twenty-five patients entered remission and 37 patients developed drug resistance or adverse effects that necessitated a drug change. The MTHFR 677T allele in molar tissue was significantly related to the need for drug change (P=0.006; odds ratio [OR], 3.13; 95% confidence interval [CI], 1.31-7.49), in contrast to MTHFR 1298C (P=0.18; OR, 0.63; 95% CI, 0.32-1.25). The MTHFR 677T and 1298C alleles obtained from patients' blood DNA were not related to MTX treatment outcome (P=0.49; OR 1.31; 95% CI, 0.61-2.91 and P=0.10; OR 0.52; 95% CI, 0.22-1.15, respectively). These data demonstrate for the first time that the genotype of MTHFR 677TT in molar tissue is associated with ineffective MTX treatment in Japanese low-risk GTN patients.

    Negative cognitive bias and aberrant neural processing of self-referent emotional words seem to be trait-marks of depression. However, it is unclear whether these neurocognitive changes are present in unaffected first-degree relatives and constitute an illness endophenotype. Fifty-three healthy, never-depressed monozygotic or dizygotic twins with a co-twin history of depression (high-risk group: n = 26) or no first-degree family history of depression (low-risk group: n = 27) underwent neurocognitive testing and functional magnetic imaging (fMRI) as part of a follow-up cohort study. Participants performed a self-referent emotional word categorisation task and free word recall task followed by a recognition task during fMRI. Participants also completed questionnaires assessing mood, personality traits and coping strategies. High-risk and low-risk twins (age, mean ± SD: 40 ± 11) were well-balanced for demographic variables, mood, coping and neuroticism. High-risk twins showed lower accuracy during self-referent categorisation of emotional words independent of valence and more false recollections of negative words than low-risk twins during free recall. Functional MRI yielded no differences between high-risk and low-risk twins in retrieval-specific neural activity for positive or negative words or during the recognition of negative versus positive words within the hippocampus or prefrontal cortex. The subtle display of negative recall bias is consistent with the hypothesis that self-referent negative memory bias is an endophenotype for depression. High-risk twins' lower categorisation accuracy adds to the evidence for valence-independent cognitive deficits in individuals at familial risk for depression. Copyright © 2017 Elsevier B.V.

    The current trend in the management of low risk differentiated thyroid carcinoma is to follow less aggressive strategies. To assess the long-term morbidity and mortality outcomes of low-risk papillary thyroid carcinoma (PTC) patients undergoing minimal intervention. We retrospectively analyzed 137 patients with low-risk PTC (stage I: n=77; stage II: n=60). Of these patients, 107 (Group 1) had macro-PTC and underwent near-total thyroidectomy and received postoperatively 50mCi RAI. The remaining 30 patients (Group 2) had micro-PTC (<1cm) and were treated only by means of near-total thyroidectomy. The median follow-up for Group 1 patients was 10 years (range: 3-30). At 1-year evaluation, 8 patients of Group 1 had indeterminate or incomplete biochemical response, of whom 4 had also incomplete structural response to initial therapy. Only 1 of 4 patients with structural incomplete response underwent cervical lymph node dissection and then received an additional dose of 100mCi RAI. The remaining 7 patients received only an additional dose of 100mCi RAI. These patients have been continuously followed till the present time with no recurrences or deaths (median follow-up: 17.5 years; 3-30 years). At 15 years, 2 patients of Group 1 experienced biochemical recurrence and they received 100mCi RAI. Three patients of Group 2 experienced recurrence, with 2 receiving 50mCi RAI and 1 undergoing cervical lymph node dissection with 50mCi RAI. Patients with low-risk macro-PTC treated by means of near-total thyroidectomy without PCCLND and receiving postoperatively a low dose of 50mCi RAI have excellent long-term prognosis.

    Telomere shortness in human beings is a prognostic marker of ageing, disease, and premature morbidity. We previously found an association between 3 months of comprehensive lifestyle changes and increased telomerase activity in human immune-system cells. We followed up participants to investigate long-term effects. This follow-up study compared ten men and 25 external controls who had biopsy-proven low-risk prostate cancer and had chosen to undergo active surveillance. Eligible participants were enrolled between 2003 and 2007 from previous studies and selected according to the same criteria. Men in the intervention group followed a programme of comprehensive lifestyle changes (diet, activity, stress management, and social support), and the men in the control group underwent active surveillance alone. We took blood samples at 5 years and compared relative telomere length and telomerase enzymatic activity per viable cell with those at baseline, and assessed their relation to the degree of lifestyle changes. Relative telomere length increased from baseline by a median of 0·06 telomere to single-copy gene ratio (T/S)units (IQR-0·05 to 0·11) in the lifestyle intervention group, but decreased in the control group (-0·03 T/S units, -0·05 to 0·03, difference p=0·03). When data from the two groups were combined, adherence to lifestyle changes was significantly associated with relative telomere length after adjustment for age and the length of follow-up (for each percentage point increase in lifestyle adherence score, T/S units increased by 0·07, 95% CI 0·02-0·12, p=0·005). At 5 years, telomerase activity had decreased from baseline by 0·25 (-2·25 to 2·23) units in the lifestyle intervention group, and by 1·08 (-3·25 to 1·86) units in the control group (p=0·64), and was not associated with adherence to lifestyle changes (relative risk 0·93, 95% CI 0·72-1·20, p=0·57). Our comprehensive lifestyle intervention was associated with increases in relative

    The primary aim of this study was to create reference ranges for the fetal Middle Cerebral artery Pulsatility Index (MCA PI), Umbilical Artery Pulsatility Index (UA PI) and the Cerebro-Placental Ratio (CPR) in a clearly defined low-risk cohort using the Generalised Additive Model for Location, Shape and Scale (GAMLSS) method. Prospectively collected cross-sectional biometry and Doppler data from low-risk women attending the Mater Mother's Hospital, Maternal and Fetal Medicine Department in Brisbane, Australia between January 2010 and April 2017 were used to derive gestation specific centiles for the MCA PI, UA PI and CPR. All ultrasound scans were performed between 18 + 0 and 41 + 6 weeks gestation with recorded data for the MCA PI and/or UA PI. The GAMLSS method was used for the calculation of gestational age-adjusted centiles. Distributions and additive terms were assessed and the final model was chosen on the basis of the Global Deviance, Akaike information criterion (AIC) and Schwartz bayesian criterion (SBC), along with the results of the model and residual diagnostics as well as visual assessment of the centiles themselves. Over the study period 6013 women met the inclusion criteria. The MCA PI was recorded in 4473 fetuses, the UA PI in 6008 fetuses and the CPR was able to be calculated in 4464 cases. The centiles for the MCA PI used a fractional polynomial additive term and Box-Cox t (BCT) distribution. Centiles for the UA PI used a cubic spline additive term with BCT distribution and the CPR used a fractional polynomial additive term and a BCT distribution. We have created gestational centile reference ranges for the MCA PI, UA PI and CPR from a large low-risk cohort that supports their applicability and generalisability.

    Full Text Available Abstract Background Many studies have shown that high-dose proton-pumps inhibitors (PPI do not further reduce the rate of rebleeding compared to non-high-dose PPIs but we do not know whether intravenous non-high-dose PPIs reduce rebleeding rates among patients at low risk (Rockall score Methods Subjects who received high dose and non-high-dose pantoprazole for confirmed acute PU bleeding at a tertiary referral hospital were enrolled (n = 413. They were divided into sustained hemostasis (n = 324 and rebleeding groups (n = 89. The greedy method was applied to allow treatment-control random matching (1:1. Patients were randomly selected from the non-high-dose and high-dose PPI groups who had a high risk peptic ulcer bleeding (n = 104 in each group, and these were then subdivided to two subgroups (Rockall score ≥ 6 vs. vs. 27. Results An initial low hemoglobin level, serum creatinine level, and Rockall score were independent factors associated with rebleeding. After case-control matching, the significant variables between the non-high-dose and high-dose PPI groups for a Rockall score ≥ 6 were the rebleeding rate, and the amount of blood transfused. Case-controlled matching for the subgroup with a Rockall score Conclusion Intravenous non-high-dose pantoprazole is equally effective as high-dose pantoprazole when treating low risk patients with a Rockall sore were

    Introduction Cardiopulmonary bypass (CPB) induces hemodilutional anemia, which frequently requires the transfusion of blood products. The objective of this study was to evaluate oxygen delivery and consumption and clinical outcome in low risk patients who were allocated to an hematocrit (Hct) of 20% versus 25% during normothermic CPB for elective coronary artery bypass graft (CABG) surgery. Methods This study was a prospective, randomized and controlled trial. Patients were subjected to normothermic CPB (35 to 36°C) and were observed until discharge from the intensive care unit (ICU). Outcome measures were calculated whole body oxygen delivery, oxygen consumption and clinical outcome. A nonparametric multivariate analysis of variance for repeated measurements and small sample sizes was performed. Results In a total of 54 patients (25% Hct, n = 28; 20% Hct, n = 26), calculated oxygen delivery (p = 0.11), oxygen consumption (p = 0.06) and blood lactate (p = 0.60) were not significantly different between groups. Clinical outcomes were not different between groups. Conclusion These data indicate that an Hct of 20% during normothermic CPB maintained calculated whole body oxygen delivery above a critical level after elective CABG surgery in low risk patients. The question of whether a transfusion trigger in excess of 20% Hct during normothermic CPB is still supported requires a larger prospective and randomized trial. PMID:16606474

    Cost estimates through traditional hospital accounting systems are often arbitrary and ambiguous. We used time-driven activity-based costing (TDABC) to determine the true cost of low-dose-rate (LDR) and high-dose-rate (HDR) brachytherapy for prostate cancer and demonstrate opportunities for cost containment at an academic referral center. We implemented TDABC for patients treated with I-125, preplanned LDR and computed tomography based HDR brachytherapy with two implants from initial consultation through 12-month followup. We constructed detailed process maps for provision of both HDR and LDR. Personnel, space, equipment, and material costs of each step were identified and used to derive capacity cost rates, defined as price per minute. Each capacity cost rate was then multiplied by the relevant process time and products were summed to determine total cost of care. The calculated cost to deliver HDR was greater than LDR by $2,668.86 ($9,538 vs. $6,869). The first and second HDR treatment day cost $3,999.67 and $3,955.67, whereas LDR was delivered on one treatment day and cost $3,887.55. The greatest overall cost driver for both LDR and HDR was personnel at 65.6% ($4,506.82) and 67.0% ($6,387.27) of the total cost. After personnel costs, disposable materials contributed the second most for LDR ($1,920.66, 28.0%) and for HDR ($2,295.94, 24.0%). With TDABC, the true costs to deliver LDR and HDR from the health system perspective were derived. Analysis by physicians and hospital administrators regarding the cost of care afforded redesign opportunities including delivering HDR as one implant. Our work underscores the need to assess clinical outcomes to understand the true difference in value between these modalities. Copyright © 2016 American Brachytherapy Society.

    This prospective, observational study in 988 asymptomatic or symptomatic low-risk patients without prior coronary artery disease was conducted to define the relative value of coronary artery calcium score (CACS), exercise treadmill testing (ETT), and stress myocardial perfusion single-photon emission computed tomography (SPECT) variables in predicting long-term risk stratification. CACS, ETT, and stress myocardial perfusion SPECT results predict patients' outcome. There are currently no data comparing their relative value in long-term risk stratification. Patients were stratified by Framingham risk score (FRS), with a median follow-up of 6.9 years. Cardiac events were defined as a composite of cardiac death, nonfatal myocardial infarction, and the need for coronary revascularization. Most patients (87%) were considered appropriate candidates for functional testing as defined by current appropriate use criteria. The long-term cardiac event rate was 11.2% (1.6% per year). Multivariate risk predictors in all patients and in the appropriate use cohort were abnormal SPECT (hazard ratio [HR]: 1.83 and 1.99), ETT ischemia (HR: 1.70 and 1.76), decreasing exercise capacity (HR: 1.11 and 1.17), decreasing Duke treadmill score (HR: 1.07 for both), and CACS severity (HR: 1.29 for both), respectively. Throughout the 10-year follow-up, CACS improved risk prediction, with event rates ranging from 0.6% per year (CACS ≤10) to 3.7% per year (CACS >400) (p risk prediction in all patients, in the appropriate use cohort and among those with low-risk ETT and SPECT results (all, p risk stratification beyond FRS, ETT, and SPECT results across the spectrum of clinical risk and importantly even among those who are currently considered appropriate candidates for functional testing or have low-risk functional test results.

    Women's planned place of birth is gaining increasing importance in the UK, however evidence suggests that there is variation in the content of community midwives' discussions with low risk women about their place of birth options. The objective of this study was to develop an intervention to improve the quality and content of place of birth discussions between midwives and low-risk women and to evaluate this intervention in practice. The study design comprised of three stages: (1) The first stage included focus groups with midwives to explore the barriers to carrying out place of birth discussions with women. (2) In the second stage, COM-B theory provided a structure for co-produced intervention development with midwives and women representatives; priority areas for change were agreed and the components of an intervention package to standardise the quality of these discussions were decided. (3) The third stage of the study adopted a mixed methods approach including questionnaires, focus groups and interviews with midwives to evaluate the implementation of the co-produced package in practice. A maternity NHS Trust in the West Midlands, UK. A total of 38 midwives took part in the first stage of the study. Intervention design (stage 2) included 58 midwives, and the evaluation (stage 3) involved 66 midwives. Four women were involved in the intervention design stage of the study in a Patient and Public Involvement role (not formally consented as participants). In the first study stage participants agreed that pragmatic, standardised information on the safety, intervention and transfer rates for each birth setting (obstetric unit, midwifery-led unit, home) was required. In the second stage of the study, co-production between researchers, women and midwives resulted in an intervention package designed to support the implementation of these changes and included an update session for midwives, a script, a leaflet, and ongoing support through a named lead midwife and regular

    We present device standards for low-power non-invasive electrical brain stimulation devices classified as limited output transcranial electrical stimulation (tES). Emerging applications of limited output tES to modulate brain function span techniques to stimulate brain or nerve structures, including transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), and transcranial pulsed current stimulation (tPCS), have engendered discussion on how access to technology should be regulated. In regards to legal regulations and manufacturing standards for comparable technologies, a comprehensive framework already exists, including quality systems (QS), risk management, and (inter)national electrotechnical standards (IEC). In Part 1, relevant statutes are described for medical and wellness application. While agencies overseeing medical devices have broad jurisdiction, enforcement typically focuses on those devices with medical claims or posing significant risk. Consumer protections regarding responsible marketing and manufacture apply regardless. In Part 2 of this paper, we classify the electrical output performance of devices cleared by the United States Food and Drug Administration (FDA) including over-the-counter (OTC) and prescription electrostimulation devices, devices available for therapeutic or cosmetic purposes, and devices indicated for stimulation of the body or head. Examples include iontophoresis devices, powered muscle stimulators (PMS), cranial electrotherapy stimulation (CES), and transcutaneous electrical nerve stimulation (TENS) devices. Spanning over 13 FDA product codes, more than 1200 electrical stimulators have been cleared for marketing since 1977. The output characteristics of conventional tDCS, tACS, and tPCS techniques are well below those of most FDA cleared devices, including devices that are available OTC and those intended for stimulation on the head. This engineering analysis demonstrates that with

    There have been no published recommendations for the management of low-risk chest pain in emergency departments (EDs) across India. This is despite the fact that chest pain continues to be one of the most common presenting complaints in EDs. Risk stratification of patients utilizing an accelerated diagnostic protocol has been shown to decrease hospitalizations by approximately 40% with a low 30-day risk of major adverse cardiac events. The experts group of academic leaders from the Indian College of Cardiology and Academic College of Emergency Experts in India partnered with academic experts in emergency medicine and cardiology from leading institutions in the UK and USA collaborated to study the scientific evidence and make recommendations to guide emergency physicians working in EDs across India.

    To compare intrapartum and neonatal mortality in low-risk term women starting labour in midwife-led versus obstetrician-led care. We performed a propensity score matched study using data from our national perinatal register, completed with data from medical files. We studied women without major risk factors with singleton pregnancies who gave birth at term between 2005 and 2008 in the Amsterdam region of the Netherlands. Major risk factors comprised non-vertex position of the fetus, previous Caesarean birth, hypertension, (gestational) diabetes mellitus, post-term pregnancy (≥42 weeks), prolonged rupture of membranes (>24 hours), vaginal bleeding in the second half of pregnancy or induced labour. Groups were devided by midwife-led versus obstetrician-led care at the onset of labour. The primary outcome was intrapartum and neonatal (24 hours. We studied 57 396 women. Perinatal mortality occurred in 30 of 46 764 (0.64‰) women in midwife-led care and in 2 of 10 632 (0.19‰) women in obstetrician-led care (OR 3.4, 95% CI 0.82 to 14.3). A propensity score matched analysis in a 1:1 ratio with 10 632 women per group revealed an OR for perinatal mortality of 4.0 (95% CI 0.85 to 18.9). Among low-risk women, midwife-led care at the onset of labour was associated with a statistically non-significant higher mortality rate. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Methods: A pilot randomized controlled clinical trial was designed at Motahhari Referral Hospital in 2014. Fifty-two patients with low risk, nonmetastatic gestational trophoblastic neoplasm were assigned randomly to two arms. The interventional arm included a repeat uterine curettage, and the control group received standard care (chemotherapy. All participants were followed periodically over 6 months. Primary outcome was defined as the number of chemotherapy courses in each arm. Student’s t-test and receiver operator characteristics (ROC curve were applied for statistical analysis as appropriate.Results: Fifty percent of participants who underwent re-curettage did respond to intervention with no further chemotherapy after 6 months of follow-up. The intervention arm had higher number of remissions without chemotherapy compared to those who received usual care. In the subgroup analysis, the ROC curve could predict the re-curettage treatment response by beta human chorionic gonadotropin (BhCG level significantly. No complications were reported in the intervention arm. Conclusion: Second curettage is an alternative effective procedure to decrease the need for chemotherapy among patients with low risk, nonmetastatic gestational trophoblastic neoplasm. Further clinical trials with larger sample size may be needed to determine the effective role of second curettage among patients. Keywords: gestational trophoblastic neoplasm, uterine curettage, chemotherapy

    In this study, we screened a total of 6723 consecutive patients with chest pain and ECG non-diagnostic for acute myocardial infarction (AMI) on presentation to the emergency department (ED). The aim of the study was to avoid missed AMI, improve safe early discharge and reduce inappropriate coronary care unit (CCU) admission. Chest pain patients were triaged using a clinical chest pain score and managed in a chest pain unit (CPU). Patients with a low clinical chest pain score were considered at very 'low-risk' for cardiovascular events and discharged from the ED; patients with a high chest pain score were submitted to CPU management. Observation and titration of serum markers of myocardial injury were obtained up to 6 hours. Rest or stress myocardial scintigraphy (SPECT) was performed in patients > 40 years or with > or = 2 major coronary risk factors. Exercise Tolerance Test (ETT) or Stress-Echocardiogram (stress-Echo) were performed in younger patients or with managed in the CPU. In this group, 1487 patients (representing 22% of the overall study group) were found positive for CAD, two-thirds because of delayed ECG or serum markers of myocardial injury, and one-third by Echo, SPECT or ETT. In conclusion, CPU based management allowed 22% early detection of myocardial ischaemia and 78% early discharge from the ED avoiding inappropriate CCU admission and optimizing the use of urgent angiography.

    Objective We aimed to assess the role of procalcitonin (PCT) to guide the initial selection of the antibiotic regimen for low-risk community-acquired pneumonia (CAP). Methods A single-arm clinical trial was conducted including outpatients with CAP and Pneumonia Severity Index risk classes I-II. Antimicrobial selection was based on the results of PCT measured with a rapid point-of-care testing. According to serum PCT levels, patients were assigned to two treatment strategies: oral azithromycin if PCT was Atypical organisms were more common in patients given azithromycin (18.5% vs 8.1%, respectively). The majority (93%) of patients with atypical pneumonia had low PCT levels. Clinical cure rates were 95.8% in the azithromycin group, 94.6% in the levofloxacin group, and 94.4% in the historical control group. No 30-day mortality or recurrences were observed, and the 3-year rates of recurrence and mortality were very low in both groups. Adverse events occurrence was also infrequent. Conclusion A PCT-guided strategy with a rapid point-of-care testing safely allowed selecting empirical narrow-spectrum antibiotics in outpatients with CAP.

    The role of human papilloma viruses (HPV) in malignant and nonmalignant ENT diseases and the corresponding epidemiological burden has been widely described. International head and neck oncology community discussed growing evidence that oral HPV infection contributes to the risk of oro-pharyngeal carcinoma (OPC) and recommended HPV testing as a part of the work up for patients with OPC. Polish Society of ENT Head Neck Surgery and National Chamber of Laboratory Diagnosticians have worked together to define the minimum requirements for assigning a diagnosis of HPV-related conditions and testing strategy that include HPV specific tests in our country. This paper briefly frames the literature information concerning low risk (LR) and high risk (HR) HPV, reviews the epidemiology, general guidance on the most appropriate biomarkers for clinical assessment of HPV. The definition of HPV-related cancer was presented. The article is aiming to highlight some of major issues for the clinician dealing with patients with HPV-related morbidities and to introduce the diagnostic algorithm in Poland.

    Full Text Available Prostate cancer (PC remains a cause of death worldwide. Here we investigate whether a single microfocus of PC at the biopsy (graded as Gleason 6 or less, ≤5% occupancy and the PSA <10 ng/mL can define the archetype of low-risk prostate disease. 4500 consecutive patients were enrolled. Among them, 134 patients with a single micro-focus of PC were followed up, and the parameters influencing the biochemical relapse (BR were analysed. Out of 134 patients, 94 had clinically significant disease, specifically in 74.26% of the patients with PSA <10 ng/mL. Positive surgical margins and the extracapsular invasion were found in 29.1% and 51.4% patients, respectively. BR was observed in 29.6% of the patients. Cox regression evidenced a correlation between the BR and Gleason grade at the retropubic radical prostatectomy (RRP, capsular invasion, and the presence of positive surgical margins. Multivariate regression analysis showed a statistically significant correlation between the presence of surgical margins at the RRP and BR. Considering a single micro-focus of PC at the biopsy and PSA serum level <10 ng/mL, clinically significant disease was found in 74.26% patients and only positive surgical margins are useful for predicting the BR.

    The Ten Group Classification System (TGCS) allows critical analysis according to the obstetric characteristics of women in labor: singleton or multiple pregnancy, nulliparous, multiparous, or multiparous with a previous cesarean delivery, cephalic, breech presentation or other malpresentation, spontaneous or induced labor, and term or preterm births. Labor outcomes associated with epidural analgesia may be different among the different labor classification groups. The aim of this study was to explore associations between epidural analgesia and cesarean delivery, and epidural analgesia and assisted vaginal delivery, in women classified using the TGCS. Slovenian National Perinatal Information System data for the period 2007-2014 were analyzed. All women after spontaneous onset or induction of labor were classified according to the TGCS, within which cesarean and vaginal assisted delivery rates were investigated (P cesarean delivery rates. Women in group 1 (nulliparous term women with singleton fetuses in cephalic presentation in spontaneous labor) with epidural analgesia had a higher cesarean delivery rate. In most TGCS groups women with epidural analgesia had higher assisted vaginal delivery rates. Epidural analgesia is associated with different effects on cesarean delivery and assisted vaginal delivery rates in different TGCS groups. Copyright © 2018. Published by Elsevier Ltd.

    Patients with systemic lupus erythematosus have a poor prognosis of pregnancy, since it is associated with significant maternal and fetal morbidity, including spontaneous miscarriage, pre-eclampsia, intrauterine growth restriction, fetal death and pre-term delivery. We report a case with successful pregnancy in a patient with systemic lupus erythematosus and hypertension. A 39-year-old nulliparous woman presented with systemic lupus erythematosus with antinuclear and antiphospholipid antibodies, hypertension and recurrent pregnancy loss presented for assisted reproduction. The patient responded well to enoxaparin and prednisone during both assisted reproduction and prenatal treatment. This case report indicates that prescription of immunosuppressant and blood thinners can be safely recommended throughout the whole prenatal period in patients with systemic lupus erythematosus. Enoxaparin and prednisone may be prescribed concurrently during pregnancy.

    Previous studies have suggested that development of inhibitors in previously treated patients (PTPs) may be attributable to a switch in factor VIII (FVIII) therapeutic product. Consequently, it is widely recognized that inhibitor development must be assessed in PTPs following the introduction of any new FVIII product. Following a national tender process in 2006, all patients with haemophilia A in Ireland changed their FVIII treatment product en masse to a plasma and albumin-free recombinant full-length FVIII product (ADVATE(®)). In this study, we retrospectively reviewed the case records of Irish PTPs to evaluate risk of inhibitor formation following this treatment switch. One hundred and thirteen patients participated in the study. Most patients (89%) had severe haemophilia. Only one of 96 patients with no inhibitor history developed an inhibitor. Prior to the switch in his recombinant FVIII (rFVIII) treatment of choice, this child had only experienced three exposure days (EDs). Consequently, in total he had only received 6 EDs when his inhibitor was first diagnosed. In keeping with this lack of de novo inhibitor development, we observed no evidence of any recurrent inhibitor formation in any of 16 patients with previously documented inhibitors. Similarly, following a previous en masse switch, we have previously reported that changing from a Chinese hamster ovary cell-produced to a baby hamster kidney cell-produced rFVIII was also associated with a low risk of inhibitor formation in PTPs. Our cumulative findings from these two studies clearly emphasizes that the risk of inhibitor development for PTPs following changes in commercial rFVIII product is low, at least in the Irish population.

    Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is a method broadly used for gastric cancer screening in Japan. Gastric polyp is one of the most frequent findings detected by UGI-XR, but how to handle it remains controversial. Gastric polyps of the 17,264 generally healthy subjects in Japan who underwent UGI-XR or upper gastrointestinal endoscopy (UGI-ES) in 2010 were analyzed. Of the 6,433 UGI-XR examinees (3,405 men and 3,028 women, 47.4 ± 9.0 years old), gastric polyps were detected in 464 men (13.6 %) and 733 women (24.2 %) and were predominantly developed on the non-atrophic gastric mucosa (p cancer occurred in 7 subjects (0.11 %), but none of them had gastric polyps at the beginning of the follow-up period. Of the 2,722 subjects with gastric polyps among the 10,831 UGI-ES examinees in the same period, 2,446 (89.9 %) had fundic, 267 (9.8 %) had hyperplastic, and 9 (0.3 %) had adenomatous/cancerous polyps. Gastric polyps diagnosed by UGI-XR predominantly arise on the Helicobacter pylori-negative gastric mucosa with a low risk of gastric cancer in Japan. In the prospective observation, none of the UGI-XR examinees with gastric polyps developed gastric cancer for at least 3 years subsequently.

    Full Text Available We aimed to assess the role of procalcitonin (PCT to guide the initial selection of the antibiotic regimen for low-risk community-acquired pneumonia (CAP.A single-arm clinical trial was conducted including outpatients with CAP and Pneumonia Severity Index risk classes I-II. Antimicrobial selection was based on the results of PCT measured with a rapid point-of-care testing. According to serum PCT levels, patients were assigned to two treatment strategies: oral azithromycin if PCT was <0.5 ng/ml, or levofloxacin if levels were ≥0.5 ng/ml. Primary outcome was clinical cure rate. Short-term and long-term outcomes were assessed. Results were compared with those of a historical standard-of-care control-group treated in our centre.Of 253 subjects included, 216 (85.4% were assigned to azithromycin. Pneumococcal infection was diagnosed in 26 (12% and 21 (56.8% patients allocated to azithromycin and levofloxacin groups, respectively. No patients in the azithromycin group developed bacteraemia. Atypical organisms were more common in patients given azithromycin (18.5% vs 8.1%, respectively. The majority (93% of patients with atypical pneumonia had low PCT levels. Clinical cure rates were 95.8% in the azithromycin group, 94.6% in the levofloxacin group, and 94.4% in the historical control group. No 30-day mortality or recurrences were observed, and the 3-year rates of recurrence and mortality were very low in both groups. Adverse events occurrence was also infrequent.A PCT-guided strategy with a rapid point-of-care testing safely allowed selecting empirical narrow-spectrum antibiotics in outpatients with CAP.The study is registered with ClinicalTrials.gov, number NCT02600806.

    Full Text Available Two low-dose levonorgestrel intrauterine contraceptive systems (LNG-IUSs; total content 13.5 mg [average approx. 8 μg/24 hours over the first year; LNG-IUS 8] and total content 19.5 mg [average approx. 13 μg/24 hours over the first year; LNG-IUS 13] have previously been shown to be highly effective (3-year Pearl Indices: 0.33 and 0.31, respectively, safe and well tolerated. The present subgroup analyses evaluated whether or not outcomes were affected by parity, age (18-25 vs 26-35 years, or body mass index (BMI, <30 vs ≥30 kg/m2.Nulliparous and parous women aged 18‒35 years with regular menstrual cycles (21‒35 days requesting contraception were randomized to 3 years of LNG-IUS 8 or LNG-IUS 13 use.In the LNG-IUS 8 and LNG-IUS 13 groups, 1432 and 1452 women, respectively, had a placement attempted and were included in the full analysis set; 39.2%, 39.2% and 17.1% were 18-25 years old, nulliparous and had a BMI ≥30 kg/m2, respectively. Both systems were similarly effective regardless of age, parity or BMI; the subgroup Pearl Indices had widely overlapping 95% confidence intervals. Placement of LNG-IUS 8 and LNG-IUS 13 was easier (p < 0.0001 and less painful (p < 0.0001 in women who had delivered vaginally than in women who had not. The complete/partial expulsion rate was 2.2-4.2% across all age and parity subgroups and higher in parous than in nulliparous women (p = 0.004. The incidence of pelvic inflammatory disease was 0.1-0.6% across all age and parity subgroups: nulliparous and younger women were not at higher risk than parous and older women, respectively. The ectopic pregnancy rate was 0.3-0.4% across all age and parity subgroups. Across all age and parity subgroups, the 3-year completion rate was 50.9-61.3% for LNG-IUS 8 and 57.9-61.1% for LNG-IUS 13, and was higher (p = 0.0001 among older than younger women in the LNG-IUS 8 group only.LNG-IUS 8 and LNG-IUS 13 were highly effective, safe and well tolerated regardless of age or

    Vibrational spectroscopy techniques can be applied to identify a susceptibility-to-adenocarcinoma biochemical signature. A sevenfold difference in incidence of prostate adenocarcinoma (CaP) remains apparent amongst populations of low- (e.g. India) compared with high-risk (e.g. UK) regions, with migrant studies implicating environmental and/or lifestyle/dietary causative factors. This study set out to determine the biospectroscopy-derived spectral differences between risk-associated cohorts to CaP. Benign prostate tissues were obtained using transurethral resection from high-risk (n = 11, UK) and low-risk (n = 14, India) cohorts. Samples were analysed using attenuated total reflection Fourier-transform infrared (FTIR) spectroscopy, FTIR microspectroscopy and Raman microspectroscopy. Spectra were subsequently processed within the biochemical cell region (1,800(-1)-500 cm(-1)) employing principal component analysis (PCA) and linear discriminant analysis (LDA) to determine whether wavenumber-absorbance/intensity relationships might reveal biochemical differences associated with region-specific susceptibility to CaP. PCA-LDA scores and corresponding cluster vector plots identified pivotal segregating biomarkers as 1,582 cm(-1) (Amide I/II trough); 1,551 cm(-1) (Amide II); 1,667 cm(-1) (Amide I); 1,080 cm(-1) (DNA/RNA); 1,541 cm(-1) (Amide II); 1,468 cm(-1) (protein); 1,232 cm(-1) (DNA); 1,003 cm(-1) (phenylalanine); 1,632 cm(-1) [right-hand side (RHS) Amide I] for glandular epithelium (P < 0.0001) and 1,663 cm(-1) (Amide I); 1,624 cm(-1) (RHS Amide I); 1,126 cm(-1) (RNA); 1,761, 1,782, 1,497 cm(-1) (RHS Amide II); 1,003 cm(-1) (phenylalanine); and 1,624 cm(-1) (RHS Amide I) for adjacent stroma (P < 0.0001). Primarily protein secondary structure variations were biomolecular markers responsible for cohort segregation with DNA alterations exclusively located in the glandular epithelial layers. These biochemical differences may lend vital insights into the aetiology of CaP.

    Full Text Available OBJETIVO: Analisar a concepção das nulíparas sobre o trabalho de parto e o parto. MÉTODOS: Estudo descritivo de abordagem qualitativa, com 10 nulíparas atendidas em consulta pré-natal em uma Unidade Básica de Saúde. A análise foi realizada a partir da técnica do DSC. RESULTADOS:Todas as gestantes entrevistadas sabem os tipos de parto, e mesmo assim relatam que o seu conhecimento é insuficiente, e uma consequencia disso é o fato que a maioria delas não reconhecem ao certo os sinais de parto. Muitas relatam que os conhecimentos que elas possuem, foram adquiridos a partir os familiares, e do enfermeiro da unidade. Em relação as expectativas do parto, as mesmas esperam que seja sem dor, tranqüilo e normal. CONCLUSÃO: Os objetivos propostos foram atendidos. A partir das concepções pode-se considerar a pesquisa relevante, pois é importante o entendimento sobre as concepções para que sejam traçadas estratégias que possam ampliá-las.

    Full Text Available A nonlinear robust control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems. The robust switching nonlinear controller architecture is designed based on a generalized (lower semicontinuous Lyapunov function obtained by minimizing a potential function over a given switching set induced by the parameterized nominal system equilibria. The proposed framework robustly stabilizes a compact positively invariant set of a given nonlinear uncertain dynamical system with structured parametric uncertainty. Finally, the efficacy of the proposed approach is demonstrated on a jet engine propulsion control problem with uncertain pressure-flow map data.

    Full Text Available Background: Methotrexate (Mtx is an accepted modality for conservative treatment of ectopic pregnancy. However, there is no consensus regarding its use in live ectopic pregnancy and high serum beta-human chorionic gonadotrophin (β-hCG titres. Concurrent use of intra-sac hypertonic KCl, to produce cardiac asystole with systemic Mtx potentially improve outcome in live ectopic gestations with very high serum β-hCG titres. Here a successful management of live ectopic pregnancy in a 25-year-old nulliparous woman, with very high β-hCG titres (29502.04mIU/mL, using ultrasound-guided intra-cardiac potassium chloride (KCl injection and systemic Mtx is reported. No treatment related complications were encountered. However, individualized treatment with a stringent follow-up regime is mandatory in such cases.

    ça de incisura bilateral nas artérias uterinas entre a 24ª e a 26ª semana de gestação podem ser bons indicadores de complicações gestacionais e perinatais.PURPOSE: to determine the validity of uterine artery Doppler velocimetry for the prediction of pregnancy complications in a population of low-risk nulliparae. SUBJECTS: a prospective study was conducted on 45 patients in their first pregnancy with no history of chronic diseases. Uterine artery Doppler velocimetry was performed between 24 and 26 weeks, with the determination of resistance index (RI, pulsatility index (PI, S/D ratio, and the presence or absence of incisure in the flow velocity wave. Data were analyzed by the Mann-Whitney test for non-parametric samples, and the Fisher exact test was used in the evaluation of the qualitative parameters. RESULTS: pregnancy complications were observed in twelve patients, with four cases of preeclampsia, one case of small for gestational age newborn (SGA NB, one case of SGA NB + preterm delivery (PTD, three cases of PTD, one case of fetal centralization, and two cases of presence of thick meconium in the amniotic fluid at the time of pregnancy resolution. We noted that RI (median 0.56 x 0.68, PI (median 0.98 x 1.29 and S/D ratio (median 2.2 x 2.9 were higher at the examination performed between 24 and 26 weeks in patients with complications and did not differ in preeclampsia and SGA cases. The presence of bilateral incisure showed 100 and 90% sensitivity, 60.2 and 62.5% specificity, 29.4 and 42,9% positive predictive value (PPV, and 100 and 95.2% negative predictive value (NPV for the detection of preeclampsia or SGA and of any complication of pregnancy, respectively. An altered Doppler showed 83.3 and 83.3% sensitivity, 69.7 and 69.7% specificity, 33.3 and 50.0% PPV, and 95.8 and 92.0% NPV for the detection of preeclampsia or SGA and of any complication of pregnancy, respectively. CONCLUSION: high impedanc
