RESUMEN
BACKGROUND: Public funding for fertility services within the United Kingdom is limited, and therefore, strict guidance exists regarding who can be offered treatment under the National Health Service (NHS). Body mass index (BMI) is a universal criteria adopted by both the public and private sector. This study addresses an important aspect of the impact of a raised BMI on fertility treatment outcomes. We standardise the analysis of the data by only including studies incorporating the WHO BMI criteria; the current reference point for clinicians and clinical commissioning groups in ascertaining which group of patients should receive treatment. This study is an update of the previous systematic review performed in 2010, with the inclusion of a larger number of cycles from central databases such as the Society for Assisted Reproductive Technology (SART). METHODS: An electronic literature search was conducted through the Cochrane, Medline and Embase libraries. Data extraction for each outcome measure was pooled and expressed as an odds ratio with 95% confidence intervals. Where clinical heterogeneity was evident, the random effects model was used to calculate the risk ratio and a fixed effects model was used for the remaining studies. A p value < 0.05 was considered statistically significant. RESULTS: A total of 49 studies have been identified and included in this systematic review. Overweight and obese (BMI ≥ 25 kg/m2) women have a statistically significant lower live birth rate (OR 0.81, 95% CI 0.74-0.89, p < 0.00001) following Assisted Reproductive Technology (ART) when comparisons are drawn to women with a normal BMI. An increase is also demonstrated in the number of miscarriages experienced by women with a BMI ≥ 30 kg/m2 (OR 1.52, 95% CI 1.28-1.81, p < 0.00001). CONCLUSION: Although this review concludes that a clear impact of BMI on ART outcomes is demonstrated, there remains questions as to the pathophysiology underlying these differences. This review supports the government's stringent criteria regarding BMI categories under which NHS funding is made available for ART, through a clear description of poor reproductive outcomes in women with a BMI ≥ 30 kg/m2.

Caesarean Scar Pregnancy (CSP) is an ectopic pregnancy with implantation into the niche of the uterine scar. We aimed to describe the local management of consecutive cases of CSP to develop a standard operating procedure (SOP). Between December 2019 and June 2022, there were 19,100 maternities. Of these, 23 were CSPs in 19 patients. Median BMI was 29 (range 20.5-52), median number of Caesarean deliveries (CS) was 2 (range 1-4) and 7/23 (30%) were cigarette smokers. At diagnosis, 9/23 were live pregnancies, 3/23 were retained products of conception (RPOC), 9/23 were pregnancies of uncertain viability (PUV), and 2/23 were non-viable. In six, the initial management was expectant, surgical suction evacuation with transrectal ultrasound guidance in 16, and one had a hysterectomy. The median blood loss was 100 mL (range 50-2000 mL). Two patients (9%) required a blood transfusion. Median hospital stay was 1 day (range 0-4). At follow-up after 10 weeks, no patients had an ongoing haematoma, and one had significant RPOC electing hysterectomy. Eight women were known to have 9 subsequent pregnancies (recurrent CSP n = 4, livebirth n = 2, miscarriage n = 2, tubal ectopic n = 1). Outcomes as rated by low blood loss, short hospital stay, and rare need for further intervention were favorable. Factors associated included prompt ultrasonographic diagnosis, availability of transrectal ultrasound guided surgery, and specialist follow-up, which form the basis of the SOP.
RESUMEN
OBJECTIVE: To compare the difference between micronised progesterone (MP) and medroxyprogesterone acetate (MPA) in combination with transdermal oestradiol (t-E2) on cardiovascular disease (CVD) risk markers in women diagnosed with an early menopause and premature ovarian insufficiency (EMPOI). BACKGROUND: The European Society for Cardiology has identified carotid femoral pulse wave velocity (cfPWV) as the gold standard cardiogenic biomarker for risk stratification of arterial disease. Menopause has been shown to augment the age-dependent increase in arterial stiffness, with hormone replacement therapy (HRT) being the mainstay of management of women diagnosed with EMPOI. STUDY DESIGN: A pilot randomised prospective open-label trial. Women were randomised to either cyclical MP (Utrogestan® 200mg) or MPA (Provera® 10mg) in conjunction with t-E2 (Evorel® Patches 50mcg/day) for 12 months. Seventy-one subjects were screened, and baseline data are available for 57 subjects. MAIN OUTCOME MEASURE: Carotid-femoral pulse wave velocity (cfPWV). RESULTS: PWV did not significantly change from baseline in either treatment arm. MP + t-E2 demonstrated a positive effect on traditional CVD markers, with a significant improvement seen in cardiac output (CO) (0.71±1.01mL/min, 95% CI 0.20 to 1.21) and reduction in diastolic blood pressure (DBP) (-3.43±6.31mmHg, 95% Cl -6.57 to -0.29) and total peripheral resistance (TPR) (-0.15±0.19mmHgâ minâ mL-1, 95% CI -0.24 to -0.05) after 12 months. MPA + t-E2, in contrast, did not demonstrate significant changes from baseline in traditional haemodynamic parameters. CONCLUSION: The positive changes in traditional markers were not reflected in the cardiogenic biomarker, cfPWV, which has demonstrated a higher positive predictive value for cardiovascular events than traditional measurements.

OBJECTIVE: To compare the impact of micronized progesterone (MP) or medroxyprogesterone acetate (MPA) in combination with transdermal estradiol (t-E2) on traditional coagulation factors and thrombin generation parameters in postmenopausal women diagnosed with premature ovarian insufficiency or early menopause. METHOD: Randomized prospective trial conducted in women diagnosed with premature ovarian insufficiency or early menopause and an intact uterus, recruited over 28âmonths. All participants were prescribed t-E2 and randomized to either cyclical MP or MPA using a web-based computer randomization software, Graph Pad. Thrombin generation parameters were measured at baseline and repeated after 3-months. Traditional hemostatic biomarkers were measured at baseline and repeated after 3, 6, and 12-months. Seventy-one participants were screened for the study, of whom 66 met the inclusion criteria. In total, 57 participants were randomized: 44 completed the thrombin generation assessment arm of the study, whilst 32 completed 12-months of the traditional coagulation factor screening component of the trial. RESULTS: Thrombin generation parameters did not significantly change from baseline after 3-months duration for either progestogen component when combined with t-E2, unlike the traditional coagulation factors. Protein C activity, free Protein S, and Antithrombin III levels decreased with time in both treatment arms. CONCLUSION: Fluctuations in traditional hemostatic biomarkers were not reproduced by parallel changes in thrombin generation parameters that remained neutral in both groups compared with baseline. The absence of statistically significant changes in thrombin generation for the first 3-months of hormone therapy use is reassuring and would suggest a neutral effect of both progestogens on the global coagulation assay.

A 40-year-old woman presents with recurrent secondary postpartum haemorrhage (PPH) following her third normal vaginal delivery. Histology from subsequent evacuation of the uterus confirmed that she had subinvolution of the placental implantation site. Hysterectomy is the most common method of managing this condition and recurrent PPH, most often due to significant vaginal bleeding. We present a case of subinvolution of the placental implantation site with recurrent PPH managed with medical treatment alone, to offer a fertility-sparing treatment option.

Objective: To compare the cumulative pregnancy rate (CPR) for experienced clinicians and trainees naive to the skill of embryo transfer (ET) during an assisted reproductive treatment (ART) cycle. To establish the minimum number of procedures required to achieve consistent outcomes. Method: A non-interventional retrospective observational cohort study looking at all consecutive ETs undertaken over a 5-year study period. The CPR was determined by a self-reported urinary home pregnancy test undertaken 16 days after oocyte retrieval. Results: The CPR did not differ between an experienced clinician (39%) and trainee (45%) for the first 50 (p=0.41) and last 50 (40.7% versus 42.7%) (p=0.81) ET procedures. The CPR for the individuals remained consistent with their peaks and troughs mirroring the overall success rate of the unit. This pattern continued when the data was further stratified for co-variables (age [≤37 years of age], catheter type [soft] and embryo quality [expanded blastocyst of grade ≥2]): CPRs for experienced clinicians was 65.7% (first 50 transfers) and 40.9% (last 50 transfers); CPR for trainees was 66.7% (first 50 transfers) and 53.6% (last 50 transfers); p=0.95 and p=0.37, respectively. The trainees, however, were more likely to use a stylet catheter with a 2-step transfer technique, with a cost over clinical implication. Furthermore, patients expressed a preference for an experienced clinician to perform their procedure, despite being informed that the grade of the clinician had no impact on the cycle outcome after an analysis of the unit's data. Conclusion: The clinician's grade and duration of service have not been shown to significantly impact the outcome of the ART cycle. The findings, however, should be interpreted with caution, as they reflect the culture of training in the unit, where there is a strong emphasis on adequate direct and indirect supervision. Furthermore, the relationship between the volume of work and outcomes is established in postgraduate medical education, with the exact number required to achieve clinical competence being dependent on the procedure and intensity of the workload.
