RESUMO

BACKGROUND: Hemolytic disease of the fetus and newborn (HDFN) is a potentially fatal complication in Rh-incompatible pregnancies and rarely occurs in the sensitizing pregnancy. Distinguishing RhIG from true anti-D identified is challenging. A case of severe HDFN in which a sample drawn at 28 weeks showed anti-D antibody (3+ strength) attributed to RhIG is described. RBC antibody testing early in pregnancy was negative. At birth, the infant was severely anemic and maternal anti-D titer was 1:256. This case represents a clinically significant anti-D in the sensitizing pregnancy that was missed due to confusion with RhIG. METHODS: To determine if agglutination strength could be helpful, a retrospective chart-review using both electronic and paper medical records was performed on 348 samples identified as RhIG and 52 true anti-D samples. The agglutination strength of antibody was recorded for each sample. RESULTS: For RhIG, there was an even distribution between the weak to moderate agglutination strength (w+, 1+, and 2+) results (35%, 26%, and 33%, respectively) and just 6% had a 3+ strength. Agglutination strength in patients with high titer (≥1:16) anti-D showed they often (44.4%) have 1+ or 2+ agglutination reactivity. CONCLUSIONS: These results show that agglutination strength alone does not provide reliable evidence to distinguish RhIG from high titer anti-D antibodies. We recommend that in cases where there is any uncertainty about whether the anti-D reactivity is due to RhIG, titers should be performed to rule out clinically significant anti-D antibody.

RESUMO

Information related to short- and long-term risks of children born to kidney-transplanted women remains limited. With the aim of investigating the risk of neonatal complications, and the short- and long-term risk of infections in offspring of kidney-transplanted women, all children born to kidney-transplanted women in Denmark from 1964 to 2016 were identified in a nationwide retrospective matched cohort study. A total of 124 children of kidney-transplanted women were identified and matched on gender, birth year, and number of siblings at birth 1:10 with children born to nontransplanted women identified in the Danish general population. Prevalence of low birth weight (37.9%, risk ratio [RR] = 12.61; 95% confidence interval [CI], 8.5-18.5), premature birth (46.0%, RR = 11.32; 95% CI, 8.1-15.7) and malformations (11.3%, RR = 1.98; 95% CI, 1.2-3.4) was increased in children of kidney-transplanted women compared with controls. Similarly, prevalence of hospitalization due to infection was increased during the first year of life (21.0%, RR = 1.94; 95% CI, 1.3-2.8), from age 1 to 5 (34.2%, RR = 1.89; 95% CI, 1.4-2.5), and overall (41.9%, RR = 1.67; 95% CI, 1.3-2.1). The risk of infection was also higher in children of kidney-transplanted mothers born preterm or with low birth weight compared with similar controls. In conclusion, risk of neonatal complications, malformations, and both early and late infection were increased in children born to kidney-transplanted women.

RESUMO

OBJECTIVE: Randomized controlled trials (RCTs) are considered the highest level of evidence to inform clinical practice. However, the reproducibility crisis has raised concerns about the scientific rigor of published RCT findings. Some advocate for a lower p-value threshold. We aimed to review published OB/Gyn topical RCTs in three representative OB/Gyn journals and three high impact non-OB/Gyn journals to determine if their interpretations would change with adoption of a p-value threshold for significance of 0.005. Secondarily, we evaluated if there were differences in methodologic characteristics between those that did and did not lose significance. STUDY DESIGN: A manual search was performed to identify all OB/Gyn RCTs published in the selected journals between July 2017 and June 2019. Data were collected on primary outcome(s), methodology, and p-values. We determined the proportion of primary outcomes that would remain statistically significant with adoption of a p-value significance threshold of 0.005 versus be reinterpreted as "suggestive" (defined as p-value between 0.005 and 0.05). Chi-square or Fisher's exact test were used to compare study characteristics. RESULTS: Overall, 202 RCTs met inclusion criteria; 52% in obstetrics and 48% in gynecology. Of 90 studies considered significant with p <0.05 at the time of publication, 54.4% (n = 49) would maintain significant (p < 0.005), while 45.6% (n = 41) would become suggestive using the lower threshold. Most RCTs utilized a single (90.1%) versus composite (8.9%) primary outcome type, used an intent-to-treat analysis (73.3%), and studied a drug intervention (46.5%). Methodologically, 23.7% did not prespecify analysis type, 28.2% did not meet the pre-determined sample size, and 9.4% did not report an a priori sample size calculation. Studies maintaining significance were more likely to be international and report a funding source. CONCLUSION: Adopting a p-value significance threshold of 0.005 would require reinterpretation of almost half of RCT results in the OB/Gyn literature. Highly variable methodological quality was identified. KEY POINTS: · New p-value threshold results in reinterpretation of nearly half of RCT results in OB/Gyn literature.. · Highly variable methodological quality was identified.. · Reduced use of binary interpretations of significance is necessary..

RESUMO

Unproven diagnostic tests and treatments for recurrent pregnancy loss patients can no longer be justified. The use of accepted study guidelines for conducting randomized trials, observational studies, systematic reviews and meta-analyses, diagnostic tests, animal research, and the development of standardized consensus derived outcomes would greatly improve the quality of recurrent pregnancy loss studies and their reporting.

RESUMO

BACKGROUND: Because immunological aberrations might be the cause of miscarriage in some women, several immunotherapies have been used to treat women with otherwise unexplained recurrent pregnancy loss. OBJECTIVES: The objective of this review was to assess the effects of any immunotherapy, including paternal leukocyte immunization and intravenous immunoglobulin on the live birth rate in women with previous unexplained recurrent miscarriages. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (11 February 2014) and reference lists of retrieved studies. SELECTION CRITERIA: Randomized trials of immunotherapies used to treat women with three or more prior miscarriages and no more than one live birth after, in whom all recognized non-immunologic causes of recurrent miscarriage had been ruled out and no simultaneous treatment was given. DATA COLLECTION AND ANALYSIS: The review author and the two co-authors independently extracted data and assessed study quality for all studies considered for this review. MAIN RESULTS: Twenty trials of high quality were included. The various forms of immunotherapy did not show significant differences between treatment and control groups in terms of subsequent live births: paternal cell immunization (12 trials, 641 women), Peto odds ratio (Peto OR) 1.23, 95% confidence interval (CI) 0.89 to 1.70; third-party donor cell immunization (three trials, 156 women), Peto OR 1.39, 95% CI 0.68 to 2.82; trophoblast membrane infusion (one trial, 37 women), Peto OR 0.40, 95% CI 0.11 to 1.45; or intravenous immunoglobulin, (eight trials, 303 women), Peto OR 0.98, 95% CI 0.61 to 1.58. AUTHORS' CONCLUSIONS: Paternal cell immunization, third-party donor leukocytes, trophoblast membranes, and intravenous immunoglobulin provide no significant beneficial effect over placebo in improving the live birth rate.

RESUMO

BACKGROUND: The oncogenic roles contributed by the Akt/PKB kinase family remain controversial and presumably depend on cell context, but are perceived to be modulated by an interplay and net balance between various isoforms. This study is intended to decipher whether distinct Akt kinase isoforms exert either redundant or unique functions in regulating neoplastic features of breast cancer cells, including epithelial-mesenchymal transition (EMT), cell motility, and stem/progenitor cell expansion. RESULTS: We demonstrate that overactivation of Akt signaling in nonmalignant MCF10A cells and in primary cultures of normal human mammary epithelial tissue results in previously unreported inhibitory effects on EMT, cell motility and stem/progenitor cell expansion. Importantly, this effect is largely redundant and independent of Akt isoform types. However, using a series of isogenic cell lines derived from MCF-10A cells but exhibiting varying stages of progressive tumorigenesis, we observe that this inhibition of neoplastic behavior can be reversed in epithelial cells that have advanced to a highly malignant state. In contrast to the tumor suppressive properties of Akt, activated Akt signaling in MCF10A cells can rescue cell viability upon treatment with cytotoxic agents. This feature is regarded as tumor-promoting. CONCLUSION: We demonstrate that Akt signaling conveys novel dichotomy effects in which its oncogenic properties contributes mainly to sustaining cell viability, as opposed to the its tumor suppressing effects, which are mediated by repressing EMT, cell motility, and stem/progenitor cell expansion. While the former exerts a tumor-enhancing effect, the latter merely acts as a safeguard by restraining epithelial cells at the primary sites until metastatic spread can be moved forward, a process that is presumably dictated by the permissive tumor microenvironment or additional oncogenic insults.

RESUMO

Elective repeat cesarean contributes substantially to the overall rising rate of cesarean delivery in the United States. Many women opting for an elective repeat cesarean are good candidates for a trial of labor after cesarean (TOLAC). Physicians should be able to identify women who are good candidates for TOLAC and provide accurate patient counseling to women considering TOLAC. Currently, evidence-based recommendations regarding intrapartum management should be followed in a well-equipped facility with all necessary personnel. With the selection of proper candidates and appropriate intrapartum management, outcome can be optimized for both mother and fetus.

RESUMO

BACKGROUND: Randomized controlled trials are considered the highest level of evidence but fewer than half are reproducible. A rigorous methodology improves trial quality, but reproducibility may be limited by a lack of transparency in reporting. The Consolidated Standards of Reporting Trials guidelines define reporting standards, and pretrial registration requires a predefined methodology and predefined outcomes. OBJECTIVE: We evaluated obstetrics and gynecology trials published in 6 journals in terms of their adherence to the Consolidated Standards of Reporting Trials guidelines. Second, we evaluated pretrial registration compliance and concordance between the registry and publication. Furthermore, we evaluated the differences in trial characteristics among randomized controlled trials with the highest level of compliance and those with lower levels of compliance and adherence to guidelines by journal type. STUDY DESIGN: This was a cross-sectional study of obstetrics and gynecology trials published between 2017 and 2019 in 6 journals (American Journal of Obstetrics & Gynecology, BJOG: An International Journal of Obstetrics and Gynaecology, Obstetrics & Gynecology, The Journal of the American Medical Association, The Lancet, and The New England Journal of Medicine). Randomized controlled trials were identified via PubMed and manual journal archive searches. The primary outcome was adequate compliance with the Consolidated Standards of Reporting Trials guidelines defined as ≥80% of the checklist items present. Secondary outcomes included completion of pretrial registration and concordance between the pretrial registration and publication in terms of the outcomes and sample size. We compared the characteristics between trials with adequate compliance and those with inadequate compliance. Secondary analyses included comparisons of characteristics of the trials in the top quartile for compliance with the Consolidated Standards of Reporting Trials guidelines with those of the trials in lower quartiles and compliance with guidelines in obstetrics-gynecology vs non-obstetrics-gynecology journals. In an exploratory analysis, trends in compliance with the Consolidated Standards of Reporting Trials guidelines across the study period were assessed. A post hoc sensitivity analysis evaluated the outcomes after the exclusion of 2 retracted trials. RESULTS: Of the 170 trials included, 80% (95% confidence interval, 74%-86%) were adequately compliant with the Consolidated Standards of Reporting Trials manuscript guidelines and 66% (95% confidence interval, 59%-73%) were compliant with the abstract guidelines. Nearly all trials (98%) reported pretrial registration. Concordance between pretrial registration and publication in terms of the primary outcomes was identified for 77% of the trials, concordance in terms of the secondary outcomes was observed in 32% of the trials, and concordance in terms of sample size was observed in 60% of the trials. Trials with adequate compliance were more likely to be preregistered, include an a priori power calculation, and use an intent to treat analysis. Trials in the top quartile for compliance with the Consolidated Standards of Reporting Trials guidelines were more likely to be multicenter, international, and government funded. More trials from non-obstetrics-gynecology journals were in the top quartile for compliance with the Consolidated Standards of Reporting Trials guidelines than trials from obstetrics-gynecology journals (64.9% vs 25.7%; P<.001). No significant trends in adequate compliance were identified across the study period. Results did not differ significantly in the sensitivity analysis. CONCLUSION: Of all the trials included, 20% of obstetrics-gynecology trials published in 6 high-impact journals were not compliant with the Consolidated Standards of Reporting Trials guidelines, and there were major discrepancies between pretrial registration and publication. Transparency, reproducibility, and scientific rigor in obstetrics and gynecology trial reporting needs to be improved.

RESUMO

BACKGROUND: Patient selection for the diverse surgical procedures for gastroparesis remains poorly defined. Our aim was to evaluate how patient factors have determined our surgical approach to gastroparesis. METHODS: 95 patients undergoing 105 surgical procedures for gastroparesis were reviewed. Patient factors were compared across six surgical procedures: gastric neurostimulator, pyloroplasty, neurostimulator plus pyloroplasty, sleeve gastrectomy, gastric bypass and gastrectomy. Global symptom severity was determined preoperatively and at last follow up. RESULTS: There were significant differences in etiology, BMI and gastroesophageal reflux across the various operations. Patients undergoing pyloroplasty and gastrectomy; were more likely to have a postsurgical etiology. (p < .05) Patients undergoing sleeve gastrectomy and gastric bypass were more likely to have BMI >35. (p <.05) Those undergoing sleeve gastrectomy were less likely to have gastroesophageal reflux preoperatively. (p <.05) There was no difference in preoperative clinical stage across the procedures. CONCLUSION: Patient factors influence choice of procedure in the surgical treatment of gastroparesis. Etiology of gastroparesis, BMI >35 and gastroesophageal reflux are important determinants.

RESUMO

Shortly after its inception, the Society for Academic Specialists in General Obstetrics and Gynecology recognized that no data described the composition and faculty activities of "academic generalist divisions." Consequently, in 2018, the Society for Academic Specialists in General Obstetrics and Gynecology appointed a presidential task force and conducted the current surveys of chairs and division directors and key informant interviews to understand the composition and faculty activities in divisions of academic specialists in departments of obstetrics and gynecology and propose criteria for excellence in each mission area to guide development of divisions. In 2014, with Society for Academic Specialists in General Obstetrics and Gynecology's guidance, these divisions were referred to as academic specialists divisions and the faculty within as academic specialists to emphasize that they provide specialized women's health care in academic settings. The divisions comprised approximately 30% of departments' full-time faculty (median 12). In 27% of the departments, these divisions contributed more than half of departmental revenue, and 49% contributed 26-50%. Nearly 90% of divisions provided a sizeable proportion of the department's total teaching efforts. Compensation relied more on clinical productivity than on seniority, quality, academic contributions, or academic rank. Subsequently, five performance domains were identified to help divisions define divisional excellence: clinical, education, research, service & advocacy, and academic environment. Furthermore, excellent divisions were characterized as those with outstanding clinicians and educators who emphasize scholarly productivity. Although academic specialists contribute significantly to their departments' financial, clinical, and educational productivity, many have limited opportunities for scholarly activity. Achieving divisional excellence likely will depend on the ability to recruit and retain faculty with career expectations that align with the division's prioritized performance domains.

RESUMO

Investigators generate new and innovative ideas needed to advance knowledge, while physicians want proven treatments that provide the best care for their patients. Along with advances in reproductive immunology research, there have also been controversies such as immunologic treatments for recurrent pregnancy loss. Research deficiencies that are wasteful and misleading include: over-interpretation and extrapolation from animal studies to the human, inadequate sample sizes, lack of appropriate control groups, use of surrogate markers, associations presented as causation, un-blinded testing and treatments, unreproducible results, and non-standardized outcomes. The purpose of the EQUATOR Network (Enhancing the QUAlity Of health Research) is to improve the quality of research and its publication. These guidelines (CONSORT, STROBE, PRISMA, STARD, ARRIVE) have been accepted as mandatory by virtually all major medical journals, and all investigators should prospectively incorporate them into their study designs. From the perspective of a clinician-scientist and an editor, my premise is that the purpose of much basic science research and all clinical research is to improve the medical care of patients. Unproven and costly diagnostic tests and treatments for potential immunologic clinical problems can no longer be justified. The primary and most important outcome that should be reported for all pregnancy-related immunologic studies is the live birth rate of a healthy infant. Today's clinicians and patients expect unbiased research that leads to evidence-based recommendations for practical and effective treatments.

RESUMO

OBJECTIVE: To survey authors submitting manuscripts to a leading specialty journal regarding their assessment of editorial review. The study sought factors affecting authors' satisfaction and whether authors rated the journal review processes differently from the commentary provided by different reviewers. METHODS: Participation in an online survey was offered to 445 corresponding authors of research manuscripts submitted consecutively during a 7-month period. All manuscripts received full editorial review. The survey instrument asked authors to rate six aspects of editorial comments from each of two to four reviewers and three aspects of the review process. In addition, the survey queried overall satisfaction and likelihood of submission of future manuscripts based on review experience. RESULTS: Higher ratings for overall satisfaction with manuscript review were given by authors of accepted compared with rejected manuscripts (98% compared with 80%, P<.001). Authors rated processes for submission and review more highly than editorial commentary (88% compared with 69%, P<.001), and this difference was greater among authors of rejected manuscripts. The extent to which reviewers focused on important aspects of submitted manuscripts received the lowest ratings from authors. Authors' ratings of reviewers' comments differentiated between reviewers and did not correlate with ratings of reviews by the journal's senior editors. CONCLUSION: Author feedback was more favorable among authors of accepted manuscripts, and responses differentiated among aspects of editorial review and reviewers. Author feedback may provide a means for monitoring and improvement of processes for editorial review and reviewer commentary. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVE: To evaluate our experience with the "pelvic pressure pack," a surgical technique for controlling posthysterectomy bleeding. METHODS: This is an observational descriptive report of cases collected by the authors during the years 1968-2006. Packs were constructed of various materials (eg, pillow cases, gauze sheets, plastic X-ray cassette drapes, or orthopedic stockings) filled with gauze rolls introduced abdominally and exiting the vagina. RESULTS: We report 11 new cases (10 obstetric and one gynecologic). Massive red blood cell transfusion and coagulopathy occurred in all cases. The pelvic pressure pack successfully controlled bleeding in 82% (9 of 11) of cases. Postoperative febrile morbidity occurred in most cases. There were no maternal deaths. CONCLUSION: In the contemporary management of posthysterectomy bleeding, the pelvic pressure pack appears to be a valuable surgical option, affording correction of coagulopathy and further stabilization. Given near-universal postoperative febrile morbidity in our series, prophylactic broad-spectrum antibiotic therapy should be strongly considered. We believe all obstetrician-gynecologists should be familiar with this simple, potentially life-saving technique. LEVEL OF EVIDENCE: III.

RESUMO

PURPOSE: The present investigation was initiated to examine the weight management practices among wrestlers participating in the NCAA Division I, II, and III wrestling tournaments. Part 1 examined the efficacy of body composition assessment between preseason (PRE) and postseason (POST). Part 2 examined rapid weight loss (RWL) during the 20 h preceding the weigh-in and the rapid weight gained (RWG) during the first day's competition. METHODS: Subjects include 811 competitors from Divisions I, II, and III participating in the NCAA national championship tournaments between 1999 and 2004. Measurements included relative body fatness (% BF) and weight (WT) on the day preceding the tournament and the evening of the first day. Minimal weight (MW) was computed with 5% BF. Retrospectively, MW, % BF, and WT from the previous fall were obtained for comparisons from NCAA records. RESULTS: Part 1: WT and % BF decreased significantly PRE (WT 74.0 +/- 11.1 kg; % BF 12.3 +/- 3.4%) to POST (WT 71.5 +/- 10.4 kg; % BF 9.5 +/- 1.8%), but MW (PRE MW 68.0 +/- 9.2 kg, POST MW 67.9 +/- 9.1 kg) remained unchanged. Heavier wrestlers and Division I and II wrestlers showed the greatest changes in WT and % BF. Part 2: RWL averaged (+/- SD) 1.2 +/- 0.9 kg and relative to weight 1.7 +/- 1.2%. Division I and lighter wrestlers showed the greatest change. RWG averaged 0.9 +/- 0.8 kg, or 1.3 +/- 1.2%. RWG was greater among lighter and Division I and II wrestlers. CONCLUSIONS: Minimal weight estimates PRE appear valid compared with POST. RWL and RWG are reduced significantly over previous investigations with only mat-side weigh-ins. The NCAA weight management program appears effective in reducing unhealthy weight cutting behaviors and promoting competitive equity. Efforts to institute similar programs among younger wrestlers seem warranted.
