Abstract
PURPOSE To verify which genetic abnormalities prevent embryos to blastulate in a stage-specific time. METHODS A single center retrospective study was performed between April 2016 and January 2017. Patients requiring Preimplantation Genetic Testing for Aneuploidies (PGT-A) by Next Generation Sequencing (NGS) were included. All embryos were cultured in a time-lapse imaging system and single blastomere biopsy was performed on day 3 of development. Segmental duplications and deletions as well as whole chromosome monosomies and trisomies were registered. Embryo arrest was defined if the embryo failed to blastulate 118 h post-injection. A logistic regression model was applied using the time to blastulate as the response variable and the different mutations as explanatory variables. A p value < 0.05 was considered significant. RESULTS Of the 285 biopsied cleavage stage embryos, 103 (36.1%) were euploid, and 182 (63.9%) were aneuploid. There was a significant difference in the developmental arrest between euploid and aneuploid embryos (8.7% versus 42.9%; p = 0.0001). Segmental duplications and whole chromosome monosomies were found to have a significant effect on developmental arrest (p = 0.0163 and p = 0.0075), while trisomies and segmental deletions had no effect on developmental arrest. In case of segmental duplications, an increase of one extra segmental duplication increases the odd of arrest by 159%. For whole chromosome monosomies, the odd will only increase by 29% for every extra chromosomal monosomy. Both chromosomal abnormalities remained significant after adding age as an explanatory variable to the model (p = 0.014 and p = 0.009). CONCLUSION Day 3 cleavage stage embryos with segmental duplications or monosomies have a significantly decreased chance to reach the blastocyst stage.

Abstract
A 27-year-old female with Trisomy 9 mosaicism presented to Children's Hospital Colorado for outpatient dental surgery under general anesthesia. The patient's past medical history was also significant for premature birth, gastroesophageal reflux, scoliosis and kyphosis, obesity, and developmental delay. Per her mother's report, the patient had no cardiac issues. She had undergone multiple previous general anesthetics, some of which documented respiratory complications such as laryngospasm, bronchospasm, and possible aspiration. During this anesthetic, the patient became hypotensive on induction, with sluggish response to intravenous fluids, glycopyrrolate, and ephedrine. Her electrocardiogram demonstrated what appeared to be left bundle branch block at baseline, with possible ST segment changes after induction. Due to her abnormal reaction to the induction and subsequent treatment for hypotension, an echocardiogram was performed. The patient was found to have an ejection fraction of 25%-30%. The anesthetic was uneventful for the remainder of the procedure, and following recovery, the patient was admitted by the heart failure team for further care.

Abstract
OBJECTIVE To determine the frequency and type of chromosomal aberrations in different gestational age spontaneous abortions. STUDY DESIGN In the study, 106 spontaneous abortions (SAs) were studied by comparative genomic hybridization. RESULTS The frequency of detected chromosomal aberrations was 37.7%. Numerical chromosomal aberrations were disclosed in 82.5% of the aberrant cases, while structural chromosomal aberrations-in 17.5%. Highest frequency of aberrations was detected in the blighted ovum specimens (62.5%) compared to missed and second trimester SAs (respectively, 36.0% and 34.8%). With regard to structural aberrations, the difference in the frequencies between blighted ovum specimens and second trimester SAs nearly reached statistical significance (p=0.0847). However, due to the low number of blighted ovum specimens analyzed (n=8), this result should be interpreted with due caution. The most frequently affected chromosomal arms were Xp and Xq (13.7% of aberrant chromosomal arms, each), followed by 16p (8.4%), 16q (8.4%), 15q (4.2%) and 19q (4.2%). CONCLUSIONS We describe for the first time a profile of chromosomal aberrations in SAs from different gestational ages, detected by CGH. Our results showed highest frequency of chromosome aberrations in blighted ovum specimens compared to other types of spontaneous abortions, higher rate of structural aberrations than reported before (17.5%) and some aberrations that so far were not found by CGH.

Abstract
Families with balanced chromosomal changes ascertained by unbalanced progeny, miscarriages, or by chance are interested in their probability for unbalanced offspring and other unfavorable pregnancy outcomes. This is usually done based on the original data published by Stengel-Rutkowski et al. several decades ago. That data set has never been updated. It is particularly true for the subgroup with low number of observations, to which belong reciprocal chromosomal translocations (RCTs) with breakpoint in an interstitial segment of 16q. The 11 pedigrees from original data together with the new 18 pedigrees of RCT carriers at risk of single-segment imbalance detected among 100 pedigrees of RCT carriers with breakpoint position at 16q were used for re-evaluation of the probability estimation for unbalanced offspring at birth and at second trimester of prenatal diagnosis, published in 1988. The new probability rate for unbalanced offspring after 2 : 2 disjunction and adjacent-1 segregation for the total group of pedigrees was 4 +/- 3.9% (1/25). In addition, the probability estimate for unbalanced fetuses at second trimester of prenatal diagnosis was calculated as 2/11, i.e. 18.2 +/- 11.6%. The probability rates for miscarriages and stillbirths/early deaths were about 16 +/- 7.3% (4/25) and <2% (0/25), respectively. Considering different segment lengths of 16q, higher probability rate (0/8, i.e. <6.1%) for maternal RCT carriers at risk of distal 16q segment imbalance (shorter segment) was obtained in comparison with the rate (0/10, i.e. <4.8%) for RCT at risk of proximal segment imbalance (longer segment). It supports findings obtained from the original data for RCT with other chromosomes, where the probability for unbalanced offspring generally increased with decreasing length of the segments involved in RCT. Our results were applied for five new families with RCT involving 16q, namely three at risk of single-segment imbalance [t(8;16)(q24.3;q22)GTG, ish(wcp8+,wcp16+;wcp8-,wcp16+), t(11;16)(q25;q22)GTG, and t(11;16)(q25;q13)GTG] and two with RCT at risk of double-segment imbalance [t(16;19)(q13;q13.3)GTG, isht(16;19)(q13;q13.3) (D16Z3+,16QTEL013-D19S238E+,TEL19pR-; D16Z3-, D19S238E-,TEL19pR+), and t(16;20)(q11.1;q12)GTG, m ish,t(16;20)(wcp16+,wcp20+;wcp16+,wcp20+)]. They have been presented in details to illustrate how the available empiric data could be used in practice for genetic counseling.

Abstract
The aim of the study was to carry out cytogenetic analyses in pregnancy losses. Samples of cartilage and placenta tissue were obtained prospectively from 237 pregnancy losses of more than 16 weeks of gestation (130 stillbirths, 97 induced abortions and 10 early neonatal deaths). Cartilage culture was performed in 222 samples and placental culture was initiated in 224. The overall culture success rate was 83.5%, 72.3% in stillbirths, 97% in induced abortions and 100% in early neonatal death. An abnormal karyotype was detected in 52 cases: 6.9% in stillbirths, 43.6% in induced abortions and 20% in early neonatal deaths. The rate of discrepancy between the prenatal cytogenetic results in amniotic fluid and the post-termination karyotype was 3%. The tissue of choice for cytogenetic analysis was cartilage in induced abortions and early neonatal death, and placenta in stillbirth. The majority of cases had a chromosome abnormality: multiple congenital anomalies in 74.6%, and a single major anomaly in 9.7%.

Abstract
Thirty perinatal solid tissue samples were used in a pilot study to test the efficacy of collagenase disaggregation onto coverslips, open system culture under low O2 conditions, pre-harvest incubation in bromodeoxyuridine (BrdU) and colcemid, and in situ automated harvesting. Following the success of the pilot study, the new method was applied to a further 126 consecutive diagnostic samples making a total of 156. The method reduced average tissue culture times from 17 to 8.7 days (range 2-17), improved success rates from 76 to 88 per cent, and simultaneously increased the resolution of cytogenetic analysis.

Abstract
The results of chromosome analyses on 500 cases of perinatal deaths are reported. It was found that 4.8% were chromosomally abnormal, but 90% of the chromosomally abnormal were either clinically malformed or macerated fetuses. Of the macerated fetuses, 9% were chromosomally abnormal and of these 33% had trisomy 21. The data suggest that the high loss of trisomy 21 fetuses in later stages of pregnancy is of an order sufficient to explain the discrepancy between the higher numbers of trisomy 21 detected during amniotic fluid sampling than found at birth in women of 35 years and over.

Abstract
An analysis of sex ratio was made for chromosomally normal and trisomic spontaneous abortions identified in a cytogenetic survey of spontaneous abortions. For the chromosomally normal group, the extent of maternal contamination among 46, XX abortions was determined by comparing chromosome heteromorphisms of the parents with those from the tissue samples. The sex ratio among the normal abortions was then estimated to be approximately 1.30, after correcting for the maternal contaminants and 46, XX hydatidiform moles of androgenetic origin. This estimate is significantly higher than values typically reported for newborns, indicating an effect of X-linked genes acting in utero. The sex ratio among trisomic abortions identified in the present study and in four other cytogenetic studies of spontaneous abortions was also significantly greater than 1.0, but not as high as the estimates of sex ratio for the chromosomally normal abortions. There was considerable variability among individual trisomies, and possible mechanisms leading to this variation are discussed.

Abstract
A malformed male infant with pure partial trisomy 12q (q24.1 leads to qter), resulting from an unbalanced segregation of a paternal balanced translocation t(2;12)(q37;q24.1), is described. The cytogenetic and clinical abnormalities of the proband are compared with those of four previously reported cases of partial trisomy 12q, two of which also appear to have pure trisomy of segment 12q24.1 leads to 12 qter.

Abstract
A chromosome examination was made on 11,148 consecutively live-born children: 93 had a chromosome abnormality and 192 a chromosome variant. The physical aspects of the children with chromosome abnormalities and variants were compared with those of the children with normal karyotypes. Children with aneuploid or unbalanced chromosome abnormalities were more immature or not fully developed at birth than those with normal karyotypes. Birth weight was lower in children with all types of chromosome abnormalities, including reciprocal translocations and chromosome variants. The low birth weight in children with chromosome variants was mainly due to the low birth weight of children with G variants. These children were also subject to a higher frequency of special delivery treatment. Heart disorders were increased in children with aneuploid or unbalanced chromosome abnormalities. The frequency of foetal erythroblastosis was increased in children with short Y as well as in children with acentric fragments. Neonatal mortality was higher in children with aneuploid or unbalanced chromosome abnormalities than in children with normal karyotypes.

Abstract
Two unrelated newborn infants with multiple malformations were found to have complete trisomy 9 in all cells examined. In both, the phenotype was similar, consisting of characteristic facial appearance (microphthalmia, bulbous nose, micrognathia, cleft palate, low set ears), skeletal abnormalities (dislocated joints, flexion contractures of the fingers), cardiovascular malformations (persistent left superior vena cava, ventricular septal defect), hypoplastic genitalia, renal anomalies, and central nervous system malformations. Both died during the first few hours of life. Comparison of these two infants with the previously reported cases reveals a consistent pattern of malformations and very short survival associated with trisomy 9. These cases illustrate the importance of doing chromosome studies on infants with congenital malformations dying in the newborn period and the usefulness of such studies in counselling parents regarding the risk of recurrence.

Abstract
An abnormal female infant, who survived for 10 months with almost complete trisomy 16p and monosomy of sub-band 21q22.3, is described. The chromosome anomaly was the result of an unbalanced segregation of a maternal balanced translocation t(16;21)(p11;q22.3). The partial monosomy was considered to have had little or no adverse phenotypic effect. Cases with trisomy of chromosome 16 material are reviewed. It appears that while full trisomy 16 always results in early spontaneous abortion, trisomy 16p or 16q may be compatible with limited postnatal survival.

Abstract
The karyotypes of 941 singleton and 42 twin abortuses and 4 cystic placentae were determined. 30.5% of the singletons were chromosomally abnormal; 49.8% of these were trisomic, 23.7% X-monosomics and 17.4% polyploid. 143 trisomies were identified by banding; over a third had an extra chromosome 16, more than 10% an extra 21 or 22 and about 5% an extra 2, 18 or 15. Examples of trisomy 3, 4, 8, 9, 10, 13, 14 and 20 were also encountered. Using the data from two other published studies, the prevalence of different trisomies was estimated and an attempt was made to relate the karyotype of the conceptus to its subsequent development.

Abstract
A study of 2620 pregnancies ending in spontaneous abortion revealed a CNS defect in 3.6% of embryos and fetuses, and 3% of all complete conceptuses. The type of malformation observed varied with the gestational age at expulsion, encephaloceles being predominant in earlier specimens, while more typical anencephalus and spina bifida were more common among later abortions. Chromosome abnormalities were found in 40% of abortuses with CNS defects, but were almost entirely confined to those which were still at the embryonic stage of development. 53% of the latter were chromosomally abnormal, which is the same as the proportion found among embryos without a CNS malformation. Using published life-tables of recognized pregnancies it was estimated that the prevalence of anencephalus, spina bifida, or related malformation (other than hydrocephalus), without a chromosome anomaly, is 5.3 per thousand conceptuses at the beginning of the eighth week of gestation. By comparing this with the prevalence in total births, it was further estimated that only 24% of these are born alive, with 54% aborting spontaneously and 22% being stillborn.
