Abstract Study question To examine the correlation of first cleavage and blastulation timing on euploidy rates in IVF cycles after PGT-A. Summary answer The timing of blastulation is observed earlier in the euploid embryos. What is known already Embryo evaluation is one of the most critical processes that affect the clinical outcome in IVF cycles. Conventional morphologic assessment and morphokinetic assessment using time lapse technology are performed in order to select the embryo with the higher implantation potential to be transferred. It is stated that embryos with faster developmental potential, especially early forming blastocysts, show increased euploidy rate and higher implantation potential. Study design, size, duration This study includes ICSI/PGT-A treatments completed between May 2018 and December 2019. 117 blastocysts were biopsied and their euploidy status was analyzed by NGS. These embryos resulted from 32 different ICSI treatments. PGT-A was performed due to: a) repeated IVF failure, b) advanced maternal age, c) recurrent pregnancy loss.ICSI was implemented in all cases and blastocysts were vitrified awaiting the genetic results. Single euploid blastocyst transfer followed and clinical pregnancy rate was monitored. Participants/materials, setting, methods Based on the genetic results, the biopsied embryos were divided into two categories; group A representing the euploid embryos and group B the aneuploid embryos. The timing of 1st cleavage and the timing of blastulation, by means of forming a blastocoel, were investigated and compared between the two groups. The rate of early blastocysts in the two groups was also analysed. Early blastocysts are considered those formed at 96h ±2 of embryo culture post ICSI. Main results and the role of chance After the genetic analysis of the biopsied embryos, 37 blastocysts were included in group A-Euploid embryos and 80 blastocysts in group B-Aneuploid embryos. The mean time of the 1st cleavage division was similar between the two groups, with marginally no statistical significance (group A-euploid:25.9h, group B-aneuploid: 26.9h ,p>0.05). Regarding the blastulation time, it was achieved earlier in group A-Euploid, at a mean time of 102.6h, compared to the mean time of 106h in group B-Aneuploid (p < 0.05). Between the cohort of the Euploid embryos (group A), there was a higher rate of early blastulating embryos, compared to the cohort of aneuploid embryos (Group B) (24% VS 17.5%), although it was not statistically significant (p > 0.05). After transferring 1 euploid blastocyst, the ongoing pregnancy rate was monitored in 76.5%, independently of the 1stcleavage and blastulation time of the transferred embryo. Limitations, reasons for caution Further investigation in larger randomized studies is required, as only a limited number of cases were included in this study. Further analysis of the ongoing pregnancy rate between the euploid blastocysts, depending on other morphokinetic parameters would be of paramount significance, as well. Wider implications of the findings: High clinical pregnancy rates observed independently of the analyzed time points, indicate high success rates obtained after PGT-A/NGS. Additionally, success rates show that trophectoderm biopsy is not hazardous for the embryo viability, if performed properly. Concluding, genetic testing combined with time-lapse microscopy may provide further information to improve IVF outcomes. Trial registration number N/A

Abstract STUDY QUESTION Is pregnancy success rate after a concise infertility work-up the same as pregnancy success rate after the traditional extensive infertility work-up? SUMMARY ANSWER The ongoing pregnancy rate within a follow-up of 1 year after a concise infertility work-up is significantly lower than the pregnancy success rate after the traditional and extensive infertility work-up. WHAT IS KNOWN ALREADY Based on cost-effectiveness studies, which have mainly focused on diagnosis, infertility work-up has become less comprehensive. Many centres have even adopted a one-stop approach to their infertility work-up. STUDY DESIGN, SIZE, DURATION We performed a historically controlled cohort study. In 2012 and 2013 all new infertile couples (n = 795) underwent an extensive infertility work-up (group A). In 2014 and 2015, all new infertile couples (n = 752) underwent a concise infertility work-up (group B). The follow-up period was 1 year for both groups. Complete follow-up was available for 99.0% of couples in group A and 97.5% in group B. PARTICIPANTS/MATERIALS, SETTING, METHODS The extensive infertility work-up consisted of history taking, a gynaecological ultrasound scan, semen analysis, ultrasonographic cycle monitoring, a timed postcoital test, a timed progesterone and chlamydia antibody titre. A hysterosalpingography (HSG) was advised routinely. The concise infertility work-up was mainly based on history taking, a gynaecological ultrasound scan and semen analysis. A HSG was only performed if tubal pathology was suspected or before the start of IUI. Laparoscopy and hormonal tests were only performed if indicated. Couples were treated according to the diagnosis with either expectant management (if the Hunault prognostic score was >30%), ovulation induction (in case of ovulation disorders), IUI in natural cycles (in case of cervical factor), IUI in stimulated cycles (if the Hunault prognostic score was <30%) or IVF/ICSI (in case of tubal factor, advanced female age, severe male factor and if other treatments remained unsuccessful). The primary outcomes were time to pregnancy and the ongoing pregnancy rates in both groups. The secondary outcomes were the number of investigations, the distribution of diagnoses made, the first treatment (started) after infertility work-up and the mode of conception. MAIN RESULTS AND THE ROLE OF CHANCE The descriptive data, such as age, duration of infertility, type of infertility and lifestyle habits, in both groups were comparable. In group A, more than twice the number of infertility investigations were performed, compared to group B. An HSG was made less frequently in group B (33% versus 42%) and at a later stage. A Kaplan–Meier curve shows a shorter time to pregnancy in group A. Also, a significantly higher overall ongoing pregnancy rate within a follow-up of 1 year was found in group A (58.7% versus 46.8%, respectively, P < 0.001). In group A, more couples conceived during the infertility work-up (14.7% versus 6.5%, respectively, P < 0.05). The diagnosis cervical infertility could only be made in group A (9.3%). The diagnosis unexplained infertility differed between groups, at 23.5% in group A and 32.2% in group B (P < 0.001). LIMITATIONS, REASONS FOR CAUTION This was a historically controlled cohort study; introduction of bias cannot be ruled out. The follow-up rate was similar in the two groups and therefore could not explain the differences in pregnancy rate. WIDER IMPLICATIONS OF THE FINDINGS Re-introduction of an extensive infertility work-up should be considered as it may lead to higher ongoing pregnancy rates within a year. The therapeutic effects of HSG and timing of intercourse may improve the fertility chance. This finding should be verified in a randomized controlled trial.

Abstract Study question Is there a difference in ART cycle results after frozen embryo transfer (FET), depending on whether blastocysts were cryopreserved on day 5 or 6? Summary answer There’s no statistical difference in the clinical pregnancy rate (CPR), life birth rate (LBR), miscarriage rate (MR) between embryos frozen on day 5 and 6. What is known already Currently, opinions differ regarding this topic. Previous studies demonstrated no difference in ongoing pregnancy rates between embryos frozen on day 5 (group A) or day 6 (group B) after FET. However, metanalysis (2019) suggested higher CPR and LBR after transferring embryos from group A rather than group B. It has also been established that ovarian stimulation leads to endometrial changes that result in deleterious effects on the implantation window and endometrial receptivity. Consequently, fresh transfers were excluded. Due to hormonal priming of endometrial receptivity, the same pregnancy outcomes should be expected with frozen-thawed blastocysts (day 5 vs 6). Study design, size, duration Retrospective cohort study was conducted between January 2015 and December 2018 with selected group of patients under 40 years of age. Group A consisted of 2275 cryotransfers of blastocyst expanded on day 5; group B included 170 cryotransfers of blastocyst on day 6. Both groups had an average of 1,52 embryos transferred per patient. Participants/materials, setting, methods Embryos were vitrified and warmed with Cryotop method (Kitazato, BioPharma). Blastocysts were scored according to Gardner and Schoolcraft grading system. Only expanded on day or 6 blastocysts of excellent and good (AA, AB, BA, BB) quality were selected. The embryos were cultured in CSC medium (Irvine Scientific) for 2–4 hours prior intrauterine transfer. The cycles with donor gametes, surrogacy and preimplantation genetic testing (PGT) were excluded. Statistical validity was assessed by Pearson’s chi-squared test. Main results and the role of chance The rates of the CPR, the ongoing pregnancy rate (OPR) and the LBR between group A and B were 50,8% (1157/2275) vs 46,5% (79/170) (p = 0,26), 37,4% (852/2275) vs 37,0% (63/170) (p = 0,91), 36,5% (832/2275) vs 35,2% (60/170) (p = 0,73) respectively and no significant differences were found in each category. Moreover, similarly there were no significant differences in the miscarriage rate 26,0% (301/1157) and 21,5% (17/79) (p = 0,37) as well Limitations, reasons for caution The study is limited due to uneven distribution of patients in both groups and by a low number of participants. The grading of blastocysts’ quality is also subjected to a human factor. Wider implications of the findings: This study confirms that frozen-thawed blastocysts do not seem to exhibit a difference in the CPR, OPR, LBR and MR whether they were expanded on day 5 or day 6. The cryopreservation of day 6 blastocyst can increase the chances of the patient for the positive outcome. Trial registration number Not applicable

Abstract Study question Objective was to assess whether adjusting starting day of intramuscular progesterone the day of vaginal supplementation versus day of embryo transfer or later, might affect the outcome of the cycle. Summary answer additional injection of intramuscular progesterone the day of progesterone initiation or later, is not likely to be more effective on live birth and miscarriage rates. What is known already There is no consensus on the most effective method of endometrium preparation prior to FET. However, many studies report that high serum progesterone concentration during the implantation period is associated with optimal live birth rates. Adjusting progesterone treatment the day of embryo transfer seems to be too late and ineffective for rescuing low progesterone levels and should be done before. Study design, size, duration In this single center prospective study from October 2019 to november 2020, 239 patients undergoing hormonal replacement therapy protocol for frozen embryo transfer were randomly divided into two groups: additional injection of intramuscular progesterone the day of progesterone initiation or intramuscular progesterone the day of embryo transfer. We compare these results to our previous protocol beginning intramuscular progesterone day 22 of the treatment. Participants/materials, setting, methods Our frozen embryo transfer protocol consists to initiate GnRH agonist the day 1 of the cycle. After 14 days of estrogens, we introduce vaginal progesterone, prior to embryo transfer. Patients in group A received an additional injection of intramuscular progesterone the day of progesterone initiation. The group B received intramuscular progesterone the day of embryo transfer. For both, intramuscular injection of progesterone was followed every 3 days. Main results and the role of chance 239 patients were enrolled in this study, 125 in the group A and 114 in the group B. The ongoing pregnancy rate in the group A was 26.4 % and miscarriage rate 7.2%, not statistically different from ongoing pregnancy rate and miscarriage rate of women in the group B (22.81 %, p = 0.66/ 6.14%, p = 0.8). The ongoing pregnancy rate in the group D22 was 24.89 % et miscarriage rate 7.2%, not statistically different from ongoing pregnancy rate of women in the group A and B (p = 0.78 and p = 0.31). Limitations, reasons for caution The main limitation of our study is the lack of randomization for the group with additional progesterone IM on day 22. The study is actually followed to enroll more patients in 3 different groups. Wider implications of the findings This study tries to determine optimal adaptive management of hormonal replacement treatment for embryo transfer in patients with potential low progesterone values.

Abstract Study question Does exposure of embryos to double vitrification and double warming affect the chances of ongoing pregnancy for patients undergoing PGT-A and transfer euploid embryos? Summary answer Our analysis shows that there is no statistically significant difference in implantation or ongoing pregnancy rate between single or double vitrification/warming cycles. What is known already The use of PGT-A is increasing in the last years and progressively more patients opting in for this, in order to reduce time to pregnancy. Implantation failures prior to genetic testing or the incidence of no-result embryos post PGT-A are some of the scenarios that expose the embryos to multiple rounds of vitrification/warming cycles. The exact effect that such exposure has on embryos is still to be investigated and confirmed as to whether it affects the outcome (i.e. implantation/ongoing pregnancy rate) or the future health of the child. Study design, size, duration Our analysis is a retrospective observation study of data collected from 151 consecutive frozen euploid embryo transfers (FET). These were performed at a single centre between January-December 2020. Two groups were created for this study. The first group includes euploid embryos that were transferred post being exposed to single vitrification/warming (n = 126). In the second group euploid embryos were exposed twice to vitrification/warming (n = 25). Statistical analysis using chi-square test and statistical significance was calculated when p ≤ 0.05. Participants/materials, setting, methods Blastocysts from 151 patients were split into two groups based on the number of vitrification/warming cycles that they underwent prior to FET. The first group includes embryos that were subjected to trophectoderm biopsy and were then vitrified (n = 126). The second group includes embryos that were initially vitrified without undergoing PGT-A analysis. Following implantation failures, their remaining embryos were warmed, biopsied and re-vitrified. Post PGT-A analysis euploid embryos were then re-warmed and transferred (n = 25). Main results and the role of chance For the first group (A), 450 blastocysts (day 5–7) were subjected to trophectoderm biopsy, where 5-cells taken, and embryos were then vitrified. Post PGT-A analysis 260 euploid embryos identified. From them 126 embryos transferred in frozen replacement cycles, where the mean embryo age for the group was 36.1±4.2. The grade of embryos transferred were of 4BC or better based on Gardner’s grading system. The implantation and ongoing pregnancy rate for this group was 62%. For the second group (B), 101 blastocysts (day 5–7) warmed, in order to undergo trophectoderm biopsy and were then re-vitrified. Post PGT-A analysis 49 euploid embryos identified. From them, 25 embryos transferred in frozen replacement cycles, where the mean maternal age for the group was 35.05±5.2. The grade of embryos transferred were of similar quality to group A. The implantation and ongoing pregnancy rate for this group was 64%. Statistical analysis confirmed that there is no statistical difference between the groups (p = 0.74). In addition, 60% of patients (n = 5) who had double vitrification, double biopsy and double warming have ongoing pregnancy. In conclusion, for transferrable quality euploid blastocysts, double vitrification has comparable reproductive outcomes as in single vitrification, thereby supporting the efficacy of double vitrification/warming when necessary. Limitations, reasons for caution This study uses a small sample size of patients. The data are observational and were retrospectively analysed so unknown confounders could not be assessed. The addition of more cycles and further multivariate analysis, including the child’s health is essential for confirmation of the findings. However, initial results are very reassuring. Wider implications of the findings: Our study has implications for clinical practice and patient counselling. Especially in patients that they choose to undergo PGT-A with pre-vitrified embryos post implantation failures with non PGT-A tested embryos. Trial registration number N/A

Background: The main objective was to compare the outcome of single layer interrupted extra-mucosal sutures with that of double layer suturing in the closure of colostomies. Subjects and Methods: Sixty-seven patients with closure colostomy were assigned in a prospective randomized fashion into either single layer extra-mucosal anastomosis (Group A) or double layer anastomosis (Group B). Primary outcome measures included mean time taken for anastomosis, immediate postoperative complications, and mean duration of hospital stay. Secondary outcome measures assessed the postoperative return of bowel function, and the overall mean cost. Chi-square test and student t-test did the statistical analysis.. Results:  Thirty-two patients were allocated to group A and 35 patients to group B. The mean time taken for anastomosis was significantly shorter in group A (23.25 ± 1.20 min in group A vs. 36.71 ± 1.93 min in group B; P<0.001). A significant shorter duration of hospital stay was seen in group A (7.00 ± 1.778 days in group A vs. 9.74 ± 1.990 days in group B; P<0.001). The detection of bowel sound was substantially quicker in group A as compared to group B (4.56 ± 0.50 days in group A vs. 6.46±0.50 days in group B; P<0.001). There was no significant discrepancy between the two groups regarding anastomotic leak rates (P= 0.543). The mean cost of double layer intestinal anastomosis method was significantly higher than that of single layer anastomosis (P<0.001). Conclusions: The use of single layer extra-mucosal anastomosis of the intestine has the advantage of taking less time, less morbidity and cost-effective to perform with the same rate of anastomotic leak in the closure of colostomy.

In order to increase the effectiveness of assisted reproductive technologies (ART) programs, it is essential to improve and develop conditions of embryo culture prior its transfer or cryopreservation of expanded blastocysts on the day 5 or 6. The aim of the study was to assess the effect of human blastocysts’ expansion timing on clinical pregnancy rate (CPR), miscarriage rate (MR) and take-home baby rate (THBR) in frozen-thawed cycles during ART programs. The study involved 2275 frozen embryo transfers (FET) of blastocysts expanded on the day 5 (group A) and 170 FET of blastocysts expanded on the day 6 (group B). The pregnancy rates in both groups were 50.8% and 46.5% respectively. There were no statistically significant differences in clinical pregnancy rate 37.4% and 37.0%, miscarriage rate 26.0% and 21.5% in both groups, respectively. THBR, as the main indicator of efficiency in the programs with transfer of post thawed expanded blastocysts on the day 5 (group A) or 6 (group B) were 36.5% and 35.2%, respectively (the difference is insignificant). In conclusion, in cryoprotocols the day of blastocyst expansion (day 5 or 6 of development) does not statistically affect PR, MR and THBR. In FET programs the quality of blastocyst (excellent and good) should be prioritized regardless of the day of cryopreservation.

Abstract Study question Does GCSF by intrauterine route leads to better result in the treatment of thin endometrium as compared to GCSF by the subcutaneous route, in IVF-ICSI Cycles? Summary answer Yes, GCSF by intrauterine route leads to better result in the treatment of thin endometrium as compared to subcutaneous-GCSF, in ART Cycles? What is known already GCSF, is a member of the colony stimulating factor family of cytokines and growth factors. GCSF receptors are expressed in high concentration on dominant follicle, particularly at preovulatory stage.The endometrium also shows an increased expression of these receptors. GCSF concentration rises in the follicular fluid at the same time. Serum levels of GCSF are found to be in direct correlation with levels of GCSF in follicular fluid. Serum levels increase progressively from the day the embryo-transfer to the day of implantation. GCSF has been found to be beneficial in patients with thin endometrium and recurrent implantation failure. Study design, size, duration This was a RCT conducted between 2018–2019. 30 patients with thin endometrium were enrolled in each group. In either group, GCSF was given if endometrium was less than 7mm on day 14, maximum of two doses were administered. Patients undergoing frozen embryo transfer were recruited in the study, after meeting the inclusion and exclusion criteria. Primary outcome measured was increase in endometrium thickness and the secondary outcome was the clinical pregnancy rate and abortion-rate. Participants/materials, setting, methods 60 patients with thin endometrium were randomly divided into two groups. Group A: Inj. GCSF (300 mcg/1 ml) subcutaneously on Day 14 onwards alternate days for two doses. Group B: Inj. GCSF (300 mcg/1 ml) instilled slowly into the uterine cavity using an intrauterine insemination (IUI) catheter under USG guidance. Endometrial thickness was assessed after 48 h. If endometrial thickness was found to be &lt; 7 mm, a second infusion of GCSF was carried out. Main results and the role of chance In the subcutaneous group (group-A) the mean endometrial thickness before GCSF injection was 5.8 ± 0.6 mm and, after injection it increased to 6.9 ± 0.4 mm. Similarly, in the intrauterine group (group-B) the mean endometrial thickness before GCSF was 5.9 ± 0.7 which increased to a mean of 7.9 ± 0.5 after GCSF instillation. The difference between endometrial thickness before and after intrauterine infusion of GCSF was more than that in the subcutaneous group. In group-A, 08 patients conceived out of 30 patients ( clinical pregnancy rate 26.6%) and in group B 11 conceived out of 30 patients in whom GCSF was instilled intrauterine (pregnancy rate 36.6%). Thus, there was a difference in the clinical pregnancy rate in the two groups, the intrauterine group yielding a higher clinical pregnancy rate, but it was not statistically significant. Because of the thin endometrium, we found an abortion rate of 25% (2/8) in the subcutaneous-GCSF group, and an abortion rate of 18% (2/11) in the intrauterine GCSF group. Limitations, reasons for caution There are few potential limitations because of the small sample size. Confounders such as obesity, smoking and alcohol intake, presence of adenomyosis and endometriosis, were not taken into consideration. Though prevalence of obesity is usually low in Indian women. Habits of smoking and alcohol are exceedingly uncommon in Indian women. Wider implications of the findings: Use of GCSF plays an important role in management of patients of thin endometrium undergoing embryo transfer. It is an easily available and economical preparation in developing countries and the intrauterine instillation of GCSF can be easily practiced in an ART unit with good results in resistant thin endometrium patients.

A prospective double-blind study was conducted to compare the anti-emetic efficacy of ondansetron and droperidol in preventing postoperative emesis following strabismus surgery. A sample size of 213 patients was divided into three equal groups to receive ondansetron 150 μg/kg (Group A), ondansetron 75 μg/kg (Group B), or droperidol 75 fig/kg (Group C). All patients received a standardized anaesthetic technique. All episodes of emesis, recovery time, and time to tolerating oral fluids were recorded. The incidence of emesis during 24 hours was Groups A and B 19.7%, and Group C 28.2%. The lower incidence of emesis recorded by the ondansetron groups compared with the droperidol group was not statistically significant. Ondansetron at 75 μg/kg was as effective as 150 μg/kg in reducing emesis when compared with droperidol. Mean time to discharge from the recovery room was 75.3 minutes (Group A), 44.4 minutes (Group B), and 41.0 minutes (Group C). The mean time to tolerating oral fluids was 356.5 minutes (Group A), 402.8 minutes (Group B), and 378.1 minutes (Group C). There was no statistical difference in discharge times from recovery or time to tolerating oral fluids in any of the three groups.

Category: Trauma Introduction/Purpose: The aim of this study was to evaluate and compare the clinical and radiological results of internal fixation with headless cannulated screw and locking compression distal ulna hook plate for the fracture at the base of fifth metatarsal bone, Zone 1. Methods: From April 2012 to April 2015, thirty cases (29 patients) were evaluated retrospectively. The mean follow up periods was 13 months. There were divided two groups based on use of the screw (group A, n=15) or the plate (group B, n=15).We measured the displacement to diastasis of the fracture on the foot oblique radiographs taken pre- and post-operatively in each group, checked the time to bone union and the difference of the reduction distance in each group. Clinical results were evaluated using American Orthopedic Foot and Ankle Society (AOFAS) midfoot score at 12 months postoperative. Results: In group A, the mean time to union was 54.2±9.3 days, the mean displacement to diastasis improved to 0.3±0.4 mm postoperatively (p<0.001), and the mean reduction distance was 2.9±1.0 mm. In group B, the mean time to union was 41.5±7.0 days, the mean displacement to diastasis improved to 0.06±0.2 mm postoperatively (p<0.001), and the mean reduction distance was 4.1±1.6 mm. AOFAS score was verified 97.7±3.4 in group A and 98.2±3.2 in group B. The time to union was significantly different between groups A and B (p=0.01).There were no complications. Conclusion: We suggest that the plate is more effective method for the shorter union time in surgical treatment of fifth metatarsal base fractures.
