Abstract Background To evaluate the association of patient and IVF cycle characteristics with blastulation rate and formation of high-quality blastocysts Results We analyzed autologous blastocyst cycles from 2013 to 2017. Cycles were subdivided into low (< 33%), intermediate (33–66%), and high (> 66%) blastulation rates. Embryo quality was assigned by embryologists using Gardner Criteria. R statistical package was used, and the blastulation groups were compared using analysis of variance (ANOVA) for continuous variables and chi-squared tests for categorical variables. The Bonferroni correction was used to adjust for multiple comparisons. One hundred seventeen IVF cycles met our inclusion criteria. Of these, 20 (17.1%) had low, 74 (63.2%) had intermediate, and 23 (19.7%) had high blastulation rates. Low blastulation rate was associated with a lower number of blastocysts, including fewer high-quality blastocysts. The mean number of oocytes retrieved was highest (18.1) in the group with the lowest blastulation rate, and lowest (13.4) in those with the highest blastulation rate, although this did not reach statistical significance. There were no significant differences between blastulation rates and age, gravidity, prior live birth, anti-mullerian hormone, estradiol and progesterone levels on the day of ovulation trigger, follicle-stimulating hormone dose, or fertility diagnosis. Conclusions High blastulation rate is associated with a greater number of blastocysts, including a greater number of high-quality blastocysts. Higher oocyte yield, however, is not associated with improved blastulation rates. Blastulation rates, blastocyst number, and quality remain difficult to predict based on cycle characteristics alone, and oocyte yield may not be an accurate predictor of either outcome.

AbstractThe chronic nature of Chronic Endometritis (CE) along with the challenging management and infertility entailed, call for cutting-edge therapeutic approaches. This study introduces the novel treatment of intrauterine antibiotic infusion (IAI) combined with oral antibiotic administration (OAA), and it assesses respective performance against the gold standard treatment of OAA. Data sourced herein reports on treatment efficiency and fertility restoration for both patients aiming to conceive naturally or via In Vitro fertilization. Eighty CE patients, 40 presenting with recurrent implantation failure, and 40 with recurrent pregnancy loss, were enrolled in the IVF and the natural conception arm respectively. Treatment was subjected to randomization. Effectively treated patients proceeded with either a single IVF cycle or were invited to conceive naturally over a 6-month period. Combination of IAI and OAA provided a statistically significant enhanced effectiveness treatment rate (RR 1.40; 95%CI 1.07–1.82; p = 0.01). No statistically significant difference was observed regarding the side-effects rate (RR 1.33; 95%CI 0.80–2.22; p = 0.52). No statistically significant difference was observed for either arm regarding live-birth rate. Following an intention-to-treat analysis, employment of IAI corresponds to improved clinical pregnancy rate-albeit not reaching statistical significance. In conclusion, complimentary implementation of IAI could provide a statistically significant enhanced clinical treatment outcome.

Abstract Introduction Burn camps provide a unique environment and activities for children that have experienced a burn-injury. Positive outcomes from attending burn camp include increased self-esteem, decreased feelings of isolation and a greater sense of self-confidence. In a 3-year retrospective review of camper evaluations from one of the largest and longest running week-long burn camps in the nation for ages 5–17, we aimed to assess if a child’s gender, age, TBSA or ethnicity affected the impact that burn camp had on a child. Methods A 3-year retrospective review of a Burn Camp’s camper evaluation forms was conducted for campers that attended burn camp between 2017–2019. Camp rosters were reviewed to determine the camper gender, age, TBSA and ethnicity. Camper self-evaluation forms completed at the end of each camp session were reviewed to record camper responses to questions regarding their opinions on the impact camp had on them as well as how camp will impact their lives once they return home. Categorical variables were summarized as frequency and percentage, and continuous variables were described as median and range. To check the relationship between two categorical variables, Chi-square test was used. To compare the continuous variable among groups, Kruskal-Wallis ANOVA was used. Statistical significance was declared based on a p value&lt; 0.5. Results Within 2017–2019, there were 413 camper records. Participants’ demographic characteristics are summarized in Table 1. There were 208 males (50.3%) and 205 females (49.6%). The median age of campers were 11.86, 12.44 and 12.45 for 2017–2019, with the range from 5.16 years to 17.96 years. The median TBSA were 20, 20 and 18 for 2017–2019, with the range from 0.08 to 90. Collectively there were 47.7% Hispanic (n= 197); 24.2% Whites (n=100); 13.1% Black (n= 54); 4.6% Asian (n=19) and 7.7% Other (n=32). There were 395 camper self-evaluation forms submitted. Results of three questions there we were interested in are summarized collectively in Table 2. 57% of campers responded, “Yes, Definitely” to the question “After going to this event, will you feel more comfortable being around your classmates or friends?” 54% responded, “ Yes, Definitely” to the question “Do you feel more confidents in sharing your burn story with others when returning home?” and 51% responded “Yes, Definitely” to “Did you learn anything that will help you when you return home?” Conclusions In analyzing the camper responses, there was no statistically significant difference in responses comparing gender, age, TBSA or ethnicity.

Abstract Background: In this study, we compared the in vitro embryo development, embryo transfer outcome and the offspring outcome in the in vitro fertilization-embryo transfer (IVF-ET) between dry culture (DC) and humid culture (HC). Methods: Our study was divided into two parts. Firstly, we determined the fertilization rate, cleavage rate and high-quality embryo rate from 21 cycles in the DC group (N=262 oocytes) and HC group (N=263 oocytes). Secondly, we determined the embryo transfer outcome and the offspring outcome in DC group (N=184 cycles) and HC group (N=136 cycles). Results: Compared with the HC group, significant increase was observed in the high-quality embryo rate (66.1.2% vs. 55.3%, p=0.037) and implantation rate (49.8% vs. 40.6%, p=0.027) in the DC group. No statistical differences were observed in the pregnant outcome and birth defect of the offspring (p>0.05). Compared with HC, DC was associated with a higher high-quality embryo rate and a higher implantation rate after embryo transfer. Conclusions: No statistical differences were noticed in the offspring conditions between the two culture modes. Taken together, DC may serve as a promising method for IVF-ET.

Abstract Background: MicroRNAs (miRNAs) are a class of noncoding small RNAs that play important roles in many physiological processes by regulating gene expression. Previous studies have shown that the expression levels of total miRNAs increase during mouse embryonic development, and some miRNAs control the regulatory network in development progression. However, few studies have focused on the effects of miRNAs on early human embryonic development. The relationship between miRNAs and early human embryogenesis is still unknown. Results:In this study, RNA-seq data collected from sperm samples from 102 patients with a normal sperm index but treated with assisted reproductive technology (ART) were analyzed for the relationships between differentially expressed small RNAs and the fertilization rate (FR), blastocyst rate and high-quality embryo rate (HQER). The sperm samples with high hsa-mir-191 expression had a higher FR, effective embryo rate (EER) and HQER. hsa-mir-191 was used as a single indicator to predict the HQER. The receiver operating characteristic (ROC) curve had an area under the ROC curve (AUC) of 0.686. We also found that hsa-mir-191 expression is correlated with an abnormal sperm rate (cor = 0.29, p< 0.01). We also evaluated the relationship between hsa-mir-34c and early human embryo development in these 102 sperm samples and obtained negative results. Conclusions: These findings suggest that high hsa-mir-191-5p expression in sperm is associated with early human embryonic quality and that hsa-mir-191-5p could be used as a potential marker to screen high-quality sperm to improve the success rates of in vitro fertilization (IVF).

Objective: This study used the AOFAS score to assess the clinical functional results of patients who underwent tarsal coalition resection. Methods: This was a retrospective case series of patients who underwent tarsal coalition resection to correct rigid flat foot. Clinical and functional assessment was performed with the AOFAS score before and 6 months after surgical treatment. Descriptive analysis was performed for 7 patients (11 operated feet) using measurements of position and dispersion (mean, standard deviation, minimum, median and maximum value) for continuous variables and frequency tables (absolute and relative) for categorical variables. Results: The mean patient age was 10 years, 7 months, and the majority (71.43%) were male. The most affected joint was the calcaneonavicular. The right side was affected in 54.55% of the cases. The most frequent type of coalition was osseous (81.82% of the cases). The mean pre- and postoperative AOFAS scores were 32.7 and 70.2 points, respectively, which was a significant increase. Conclusion: The increased scores after coalition resection was considered the main change between the two assessments. Thus, it can be concluded that in rigid flat feet without severe hind- or forefoot deformities for which conservative treatment failed, bar resection should be the surgical procedure of choice.

Objective: The ongoing Covid-19 pandemic further increased this stress of employees. This disease, which did not have a cure and a vaccine at the beginning, increased the anxiety of the employees and forced them to live separately due to the risk of infecting family members. This study aimed to investigate the burnout levels of doctors and technicians working in Yenimahalle Training and Research Hospital Anaesthesiology and Reanimation Clinic. Materials and Methods: This study was conducted prospectively by using a questionnaire method in the Yenimahalle Training and Research Hospital. Maslach Burnout questionnaire applied to the participants. Quantitative data were expressed as %, the number of subjects as (n). The distribution of continuous variables was evaluated with the Kolmogorov-Smirnow test. Qualitative data were expressed in mean±SD (standard deviation). X2 test was used for comparison of categorical variables. Independent Student T-test was used for comparison of continuous variables. The relationship between burnout level and variables was determined by Pearson Correlation Test. The value of p<0.05 was considered statistically significant. Results: A total of 52 volunteers participated in the study. The average emotional exhaustion score of the volunteers participating in the study was 31.13±4.6, the average depersonalization score was 15.06±3.3, and the mean personal achievement score was 23.60±3.7. There was no statistically significant relationship between any of the variables and the burnout level (p>0.05). Conclusion: The high level of burnout in a clinic that is at the forefront of the fight against Covid-19, such as anesthesiology and reanimation, is important in terms of determining the situation.

The application of matrix proteins to culture systems for growth of embryos is a logical extension in the quest to better simulate the in vivo culture environment. Matrigel, a commercially available extracellular matrix product containing collagen IV, laminin, entactin, and proteoglycans isolated from mouse tumor cells, has been tested. Development of mouse pre-implantation embryos cultivated in conventional culture medium was contrasted to that of embryos grown in solubilized Matrigel medium. In the solubilized Matrigel medium, in vitro blastocyst formation and hatching were significantly enhanced over that observed in the medium alone control. Therefore, the aim of this study was to investigate the effect of solubilized Matrigel on the development of porcine embryos after in vitro fertilization. In vitro-matured oocytes were fertilized in mTBM medium with fresh spermatozoa for 6 h. Putative zygotes were cultured in PZM-3 medium supplemented with (matrigel group) or without (control group) 0.8% Matrigel for 6 days. The number of cells in blastocysts was determined by staining with Hoechst 33342. Assessment of apoptosis in blastocysts was examined by TUNEL. The statistical significance of the data was analyzed using chi-square test and Student&apos;s t-test. The addition of Matrigel appeared not to increase the proportion of blastocysts (control: 71/219, 21.8 � 2.2% vs. Matrigel: 69/220, 23.5 � 5.8%). However, the mean cell numbers were significantly increased by Matrigel (Matrigel: n = 31, 52.9 � 18.1 vs. control: n = 30, 42.3 � 14.4; P &lt; 0.01). The proportion of apoptotic cells was significantly lower in the Matrigel group (Matrigel: 4.5 � 4.2% vs. control: 6.6 � 5.5%; P &lt; 0.05). In this experiment, Matrigel appeared to increase blastocyst quality of porcine embryos. Results suggest that Matrigel, as an extracellular matrix component, may be another avenue for formulating more physiological culture systems.

We previously reported that superstimulatory (SS) treatment-induced follicular wave synchronization after ovum pickup (OPU) was effective in enhancing the quality of obtained oocytes and blastocysts derived from in vitro maturation (IVM) and fertilization (IVF; Imai et al. 2010 Reprod. Fertil. Dev. 22, 296). The present study was designed to examine the efficiency of embryo production by 4 sessions of OPU-IVF using a series of the SS treatment-induced follicular wave synchronizations. For the SS protocols, 3 consecutive SS (3CSS) and 2 separated SS (2SSS) were used. In the 3CSS group, the first OPU was performed on random days of the oestrous cycle (Day 0) and all follicles larger than 2 mm in diameter were aspirated. On Day 5, follicles larger than 8 mm in diameter were aspirated and a CIDR (InterAg, Hamilton, New Zealand) was inserted. The cows then received 20 armour units of FSH (Kawasaki-Seiyaku, Kawasaki, Japan) in twice-daily decreasing doses by IM injection from Day 7 to 10. Cloprostenol (PGF; 0.75 mg, Fujita-Pharm, Tokyo, Japan) was administered on the morning of Day 9. The second OPU was performed 48 h after PGF administration on Day 11; the CIDR was removed from the cows just before OPU. After the second OPU, donors were treated consecutively with the SS protocol mentioned above for the third and fourth OPU sessions. In the 2SSS group, donors received 2 sets of the SS treatment mentioned above, with an interval of 11 days between the second and the third OPU session. Four OPU sessions were performed every 11 days on all cows. In this study, 8 Japanese Black cows were divided into the 3CSS and 2SSS groups, and the treatment for each group was reversed after a 65-day interval as crossover trials. After OPU, Grade 1 and 2 oocytes were used for IVM and IVF, and putative zygotes were cultured as described by (Imai et al. 2006 J. Reprod. Dev. 52, S19–S29 suppl.). A part of the zygotes were cultured in a micro-well system. Data were analysed by Student’s t-test and chi-square test. There were differences (P < 0.05) in the mean (±SD) number of follicles, collected oocytes, and cultured oocytes in the 3CSS (35.0 ± 8.6 and 24.4 ± 11.2, respectively) and 2SSS (30.8 ± 10.5 and 20.2 ± 9.0, respectively) groups. There were no differences in mean percentage of blastocyst formation and Grade 1 blastocyst rates between the 3CSS (38.5 and 55.8%, respectively) and 2SSS (34.8 and 54.8%, respectively) groups. However, the mean number of blastocysts produced per OPU session was significantly (P < 0.05) higher in the 3CSS group (8.1 ± 6.3) compared with the 2SSS group (5.8 ± 4.4). These results indicate that a series of 3 consecutive SS treatments had greater efficiency in producing OPU-IVF embryos.
