RESUMO

STUDY QUESTION: Can live birth be accurately predicted following surgical resection of moderate-severe (Stage III-IV) endometriosis? SUMMARY ANSWER: Live births can accurately be predicted with the endometriosis fertility index (EFI), with adnexal function being the most important factor to predict non-assisted reproductive technology (non-ART) fertility or the requirement for ART (www.endometriosisefi.com). WHAT IS KNOWN ALREADY: Fertility prognosis is important to many women with severe endometriosis. Controversy persists regarding optimal post-operative management to achieve pregnancy and the counselling of patients regarding duration of conventional treatments before undergoing ART. The EFI is reported to correlate with expectant management pregnancy rate, although external validation has been performed without specifically addressing fertility in women with moderate and severe endometriosis. STUDY DESIGN, SIZE, DURATION: Retrospective cohort study of 279 women from September 2001 to June 2016. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: We included women undergoing laparoscopic resection of Stage III-IV endometriosis who attempted pregnancy post-operatively. The EFI was calculated based on detailed operative reports and surgical images. Fertility outcomes were obtained by direct patient contact. Kaplan-Meier model, log rank test and Cox regression were used for analyses. MAIN RESULTS AND THE ROLE OF CHANCE: The follow-up rate was 84% with a mean duration of 4.1 years. A total of 147 women (63%) had a live birth following surgery, 94 of them (64%) without ART. The EFI was highly associated with live births (P < 0.001): for women with an EFI of 0-2 the estimated cumulative non-ART live birth rate at five years was 0% and steadily increased up to 91% with an EFI of 9-10, while the proportion of women who attempted ART and had a live birth, steadily increased from 38 to 71% among the same EFI strata (P = 0.1). A low least function score was the most significant predictor of failure (P = 0.003), followed by having had a previous resection (P = 0.019) or incomplete resection (P = 0.028), being older than 40 compared to <35 years of age (P = 0.027), and having leiomyomas (P = 0.037). LIMITATIONS REASONS FOR CAUTION: The main limitation of this study is its retrospective design. Imprecision was higher with low EFI due to smaller sample size in this subgroup. Finally, the EFI is somewhat subjective and could be prone to intra- and inter-observer variations. WIDER IMPLICATIONS OF THE FINDINGS: Women with a high EFI score have excellent fertility prognosis and may be advised to try to become pregnant with timed intercourse compared to women with a low score, for which prompt referral to ART seems more reasonable. Other prognostic factors can be used to guide the management of women with an intermediate EFI score. These data follow women over many years post-resection and represent longitudinal fertility data rarely demonstrated in such a cohort. The location and impact of lesions on the ability of the adnexa to function seems crucial for the fertility prognosis and should be further investigated.

RESUMO

AIMS: To examine whether women with an HbA1c of 41-49 mmol/mol (5.9-6.6%) at diagnosis of gestational diabetes are higher risk than women with an HbA1c of < 41 mmol/mol (5.9%) and whether pregnancy outcomes are improved if treated at < 24 weeks' gestation. METHODS: This was an observational study of women with gestational diabetes diagnosed by early HbA1c screening or subsequent oral glucose tolerance test at < 34 weeks' gestation who delivered at National Women's Health, Auckland, from July 2012 to June 2014. Data were extracted from the hospital database. Women with HbA1c 41-49 mmol/mol (5.9-6.6%) were divided into those seen < 24 weeks (Early, n = 134) and those seen ≥ 24 weeks (Later, n = 151). Those with HbA1c < 41 mmol/mol (5.9%) were labelled Other GDM (n = 661). RESULTS: The Early and Later groups, compared with Other GDM, had more Polynesian and fewer (non-Indian) Asian women, higher BMI and more required medication (P < 0.001). More were smokers (P = 0.007, 0.02) and more had chronic hypertension (P < 0.001, 0.02). There were higher rates of adverse outcomes in the Later group than the Other GDM group (pre-eclampsia 8.0% vs. 2.4%, P = 0.001, preterm birth 16.6% vs. 8.2%, P = 0.002, neonatal admission 15.5% vs. 9.2%, P = 0.02). Outcomes were similar between the Early group and Other GDM group (pre-eclampsia 1.5% vs. 2.4%, P = 0.5, preterm birth 10.5% vs. 8.2% P = 0.4, neonatal admission 13.6% vs. 9.2%, P = 0.12). Comparing the Early and Later groups, the Early group had less pre-eclampsia, 1.5% vs. 8.0%, adjusted P = 0.03. Other outcomes were not statistically different. CONCLUSIONS: An HbA1c of 41-49 mmol/mol (5.9-6.7%) identifies a higher-risk group of women with gestational diabetes. Overall, our data support early treatment of women with an HbA1c ≥ 41 mmol/mol (5.9%).

RESUMO

Fluoroscopy is increasingly being used as a positioning device prior to obtaining plain film radiographs. This is particularly true for those examinations where the type of projection and habitus of the patient present difficulties. An example is the examination of the lumbar spine; especially the L5/S1 projection. The purpose of this study was to determine the effect of fluoroscopy-guided positioning (FGP) on patient dose. The study assessed the difference in dose-area product (DAP) between conventional film-screen radiography (FSR) and a FGP assisted series of the lumbar spine. DAP values were monitored on 102 patients (50 FSR, 52 FGP) over 7 (4 FSR, 3 FGP) study sites. The median values for all FGP and FSR procedures were 8.3 Gy cm(2) and 12.5 Gy cm(2), respectively. The differences in doses were attributed to lower mAs and tighter collimation used in FGP assisted procedures. The study has demonstrated that it is possible to achieve lower DAP values using FGP. What now has to be asked is whether FGP should be acknowledged and further introduced into clinical practice. If so, there is a need for careful monitoring and reporting of dose so that strict protocols can be set in place to ensure the ALARA principle is enforced.

RESUMO

Effects of members of the transforming growth factor-beta (TGF-beta) family on expression of surfactant protein A (SP-A) were determined in human pulmonary adenocarcinoma cells. TGF-beta decreased SP-A content in two distinct pulmonary adenocarcinoma cell lines with bronchiolar (NCI-H441-4) and alveolar (NCI-H820) cell characteristics. TGF-beta 1, beta 2 and beta 3 were equally effective in decreasing SP-A. Effects of the TGF-beta's on SP-A content were dose dependent, EC50 approximately 20-30 pg/ml for each form of TGF-beta. TGF-beta decreased cellular SP-A content in association with decreased levels of SP-A mRNA. Inhibitory effects of TGF-beta 1 on SP-A mRNA was time dependent, reaching maximal effects within 12-24 h, after which SP-A mRNA was approximately 10% of that present in untreated cells. Maximal inhibition of SP-A mRNA was observed at 250 pg/ml TGF-beta 1. TGF-beta-dependent inhibition of SP-A expression was not associated with altered cell morphology, growth, or viability. TGF-beta family members act directly on pulmonary adenocarcinoma cells to inhibit SP-A expression by mechanisms which are mediated, at least in part, at a pretranslational level.
