IVF Errors - Is This Only the Tip of the Iceberg?

ART errors are fortunately a rare occurrence. but humans are fallible and mistakes are inevitable. As social media sensationalizes these events, we, as infertility specialists, must be vigilant in reviewing existing risk management systems and consider other options to minimize/eliminate these events. ART programs should work to emphasize honesty and transparency to improve quality of care

Relationship Between Applied Load and Clearance in Suture Knots

Ethicon Coated Vicryl absorbable sutures of different diameters were studied in order to determine if a relationship exists between the load and measured clearance. A prototype was designed to simulate knot location. Tensile tests were conducted on the suture knots followed by clearance measurements after each load level was applied. From the results it was concluded that the measured clearance was directly proportional to the amount of load applied to the suture knot. Also, based on the diameter of the suture, the smaller the diameter, the lower was the total displacement of the knot or the clearance

Using the EngagedMD Multimedia Platform to Improve Informed Consent for Ovulation Induction, Intrauterine Insemination, and In Vitro Fertilization

Objective: To study patient and provider feedback on how a multimedia platform (EngagedMD) helps patients to understand the risks and consequences of in vitro fertilization (IVF), ovulation induction (OI), and intrauterine insemination (IUI) treatments and the impact of the informed consent process. Design: Prospective survey study. Setting: IVF units in the United States. Patient(s): Six-thousand three-hundred and thirty-three patients who viewed the multimedia platform before IVF or OI-IUI treatment at 13 U.S. IVF centers and 128 providers. Intervention(s): Quantitative survey with 17 questions. Main Outcome Measure(s): Assessment of the impact of a multimedia platform on patient anxiety, comprehension, and satisfaction and provider/nurse feedback related to the informed consent process. Result(s): The survey was completed by 3,097 respondents (66% IVF treatment; 34% OI-IUI treatment) and 44 providers. Overall, 93% felt the media platform was intuitive, and 90% and 95% felt it had appropriate duration and detail, respectively. Most agreed/strongly agreed it better prepared them to consent (88%), increased their comfort in pursuing treatment (77%) and increased their satisfaction with their care (83%). Compared with the OI-IUI group, statistically significantly more participants who viewed the IVF media platform strongly agreed that the comprehension questions reinforced key concepts (47% vs. 40%), educated them about treatment risks (55% vs. 44%), helped them ask providers informed questions (45% vs. 36%), and better prepared them to sign consent forms (46% vs. 37%). Overall, 63% of providers felt that the media platform improved patient learning, made patients more accountable, and standardized information dissemination. Conclusion(s): The EngagedMD media platform improves patient knowledge, satisfaction, and control over medical decision making and better prepares patients to give informed consent. Furthermore, it is well-liked by providers and is easily implemented

Normal Ovulatory Women with Polycystic Ovaries Have Hyperandrogenic Pituitary-Ovarian Responses To Gonadotropin-Releasing Hormone-Agonist Testing

Women with polycystic ovary syndrome (PCOS) have chronic anovulation and hyperandrogenism and frequently have abnormalities in their lipid profiles and insulin/insulin-like growth factor axis that increase their lifetime risk for cardiovascular disease. Normal ovulatory women may have polycystic ovaries on ultrasonography and yet lack the clinical features of PCOS. To further explore whether ovulatory women without clinical/biochemical hyperandrogenism but with polycystic appearing ovaries (ov-PAO) have subclinical features of PCOS, we prospectively characterized 26 ov-PAO women and matched them by age and body mass index to 25 ovulatory women with normal appearing ovaries (ov-NAO) and to 22 women with PCOS. After an overnight fast, all women had baseline endocrine and metabolic assessments. In addition, a subset of each group of women underwent GnRH-agonist (leuprolide acetate 1 mg sc) testing, ACTH stimulation, and an insulin tolerance test (ITT). At baseline, ov-PAO and ov-NAO women had similar endocrine profiles (LH, LH:FSH, androstenedione, and DHEAS). Compared with ov-NAO, 31% of ov-PAO women had reduced glucose responses after insulin (Kitt), suggesting mild insulin resistance, and 35% had high density lipoprotein levels below 35 mg/dL, a level considered to represent significant cardiovascular risk. After GnRH-agonist, ov-PAO women had response patterns in LH, total testosterone, and 17-hydroxyprogesterone (17-OHP) that were intermediate between ov-NAO and women with PCOS. Ovarian responses were above the normal range in 30–40% of women with ov-PAO. In ov-PAO, peak responses of LH after leuprolide correlated with triglyceride levels (P < 0.05) and peak responses of 17-OHP correlated inversely with Kitt values (P < 0.05). No significant differences were noted with ACTH testing. In conclusion, occult biochemical ovarian hyperandrogenism may be uncovered using GnRH-agonist in ovulatory women with ov-PAO, while adrenal responses remain normal. Subtle metabolic abnormalities may also be prevalent

Acute Modulation of Adipose Tissue Lipolysis by Intravenous Estrogens

Objective: The aim of this study was to determine whether intravenous (IV) conjugated estrogens (EST) acutely enhance the suppression of whole-body or regional subcutaneous adipose tissue (SAT) lipolysis by insulin in postmenopausal women. Research Methods and Procedures: We assessed whole-body lipolysis by [2H5]glycerol rate of appearance (GlycRA) and abdominal and femoral SAT lipolysis (interstitial glycerol; GlycIS) by subcutaneous microdialysis. Postmenopausal women (n = 12) were studied on two occasions, with IV EST or saline control (CON), under basal conditions and during a 3-stage (4, 8, and 40 mU/m2/ min) hyperinsulinemic, euglycemic clamp. Ethanol outflow/inflow ratio and recovery of [13C] glycerol during microdialysis were used to assess blood flow changes and interstitial glycerol concentrations, respectively. Results: Compared with CON, EST did not affect systemic basal or insulin-mediated suppression of lipolysis (GlycRA) or SAT nutritive blood flow. Basal GlycIS in SAT was reduced on the EST day. However, insulin-mediated suppression of lipolysis in SAT was not significantly influenced by EST. Discussion: These findings suggest that estrogens acutely reduce basal lipolysis in SAT through an unknown mechanism but do not alter whole-body or SAT suppression of lipolysis by insulin.

Impact of Hormone Replacement Therapy on Exercise Training-Induced Improvements in Insulin Action in Sedentary Overweight Adults

Exercise training (ET) and hormone replacement therapy (HRT) are both recognized influences on insulin action, but the influence of HRT on responses to ET has not been examined. In order to determine if HRT use provided additive benefits for the response of insulin action to ET, we evaluated the impact of HRT use on changes in insulin during the course of a randomized, controlled, aerobic ET intervention. Subjects at baseline were sedentary, dyslipidemic, and overweight. These individuals were randomized to six months of one of three aerobic ET interventions or continued physical inactivity. In 206 subjects, an insulin sensitivity index (SI) was obtained with a frequently sampled intravenous glucose tolerance test pre- and post-ET. Baseline and post-intervention fitness, regional adiposity, general adiposity, skeletal muscle biochemistry and histology, and serum lipoproteins were measured as other putative mediators influencing insulin action. Two-way analyses of variance were used to determine if gender or HRT use influenced responses to exercise training. Linear modeling was used to determine if predictors for response in SI differed by gender or HRT use. Women who used HRT (HRT+) demonstrated significantly greater improvements in SI with ET than women not using HRT (HRT-). In those HRT+ women, plasma triglyceride change best correlated with change in SI. For HRT- women, capillary density change, and for men, subcutaneous adiposity change, best correlated with change in SI. In summary, in an ET intervention, HRT use appears associated with more robust responses in insulin action. Also, relationships between ET induced changes in insulin action and potential mediators of change in insulin action are different for men, and for women on or off HRT. These findings have implications for the relative utility of ET for improving insulin action in middle-aged men and women, particularly in the setting of differences in HRT use.

Reproductive and hormonal factors and mortality among women with colorectal cancer in the NIH-AARP Diet and Health Study

BACKGROUND: Although use of menopausal hormone therapy (MHT) and some reproductive factors have been associated with colorectal cancer (CRC) risk, relations between these factors and survival after CRC diagnosis are unclear. METHODS: Among 2053 post-menopausal women diagnosed with incident CRC in the NIH-AARP Diet and Health Study, we calculated hazard ratios (HRs) and 95% confidence intervals (CIs) using multivariable Cox proportional hazards regression to test associations between oral contraceptive (OC) use, menarche age, age at first birth, parity, menopausal age, and MHT use with all-cause and CRC-specific mortality. RESULTS: There were 759 deaths (332 CRC-related deaths) over a median follow-up of 7.7 years. We observed no statistically significant associations between OC use, menarche age, age at first birth, parity, menopausal age, and mortality. Compared with never MHT use, former use was not associated with mortality, but we found an inverse association among baseline current users, for both all-cause (HR=0.79, 95% CI 0.66–0.94) and CRC mortality (0.76, 0.59–0.99). CONCLUSION: Future studies should further focus on the mechanisms by which exogenous oestrogen exposure might affect tumour progression and CRC survival

Mann and gender in Old English prose : a pilot study

It has long been known that OE mann was used in gender-neutral as well as gender-specific contexts. Because of the enormous volume of its attestations in Old English prose, the more precise usage patterns of mann remain, however, largely uncharted, and existing lexicographical tools provide only a basic picture. This article aims to present a preliminary study of the various uses of mann as attested in Old English prose, particularly in its surprisingly consistent use by an individual author, namely that of the ninth-century Old English Martyrology. Patterns emerging from this text are then tested against other prose material. Particular attention is paid to gender-specific usage, examples of which are shown to be exceptional for a word which largely occurs in gender-neutral contexts.Publisher PDFPeer reviewe

Effects of long-term moderate exercise and increase in number of daily steps on serum lipids in women: randomised controlled trial [ISRCTN21921919]

BACKGROUND: This study was designed to evaluate the effects of a 24-month period of moderate exercise on serum lipids in menopausal women. METHODS: The subjects (40–60 y) were randomly divided into an exercise group (n = 14) and a control group (n = 13). The women in the exercise group were asked to participate in a 90-minute physical education class once a week and to record their daily steps as measured by a pedometer for 24 months. RESULTS: Mean of daily steps was significantly higher in the exercise group from about 6,800 to over 8,500 steps (P < 0.01). In the control group, the number of daily steps ranged from 5,700 to 6,800 steps throughout the follow-up period. A significant interaction between the exercise group and the control group in the changes og total cholesterol (TC), high-density lipoprotein cholesterol (HDLC) and TC : HDLC ratio could be observed (P < 0.05). By multiple regression analysis, the number of daily steps was related to HDLC and TC : HDLC levels after 24 months, and the changes in TC and HDLC concentrations. CONCLUSIONS: These results suggest that daily exercise as well as increasing the number of daily steps can improve the profile of serum lipids
