Predicting adult height from DNA variants in a European-Asian admixed population
Abstract Accurate genomic profiling for adult height is of high practical relevance in forensics genetics. Adult height is a classical reference trait in the field of human complex trait genetics characterized by highly polygenic nature and relatively high heritability. A meta-analysis of genome-wide association studies by the Genetic Investigation of Anthropocentric Traits (GIANT) consortium has identified 697 DNA variants associated with adult height in Europeans; however, whether...

Age estimation based on different molecular clocks in several tissues and a multivariate approach: an explorative study
Abstract Several molecular modifications accumulate in the human organism with increasing age. Some of these "molecular clocks" in DNA and in proteins open up promising approaches for the development of methods for forensic age estimation. A natural limitation of these methods arises from the fact that the chronological age is determined only indirectly by analyzing defined molecular changes that occur during aging. These changes are not linked exclusively to the expired life span...

Deficiency of antisense lncRNA Gm48853 resulted in embryonic lethality and impaired placental development in mice
Qi-Yun Qin, Wei-Jia Zeng, Chu-Yue Peng, Yu-Fang Zheng, Hong-Yan Wang

Reproductive and Developmental Medicine 2019 3(1):5-10

Objective: Long noncoding RNAs (lncRNAs) play important roles in embryonic development and in various diseases. Gm48853 is a predicted natural antisense lncRNA gene of unknown function. The present study aimed to investigate its expression and function. Methods: Quantitative reverse transcription-polymerase chain reaction and sequencing were used to detect the expression of Gm48853 antisense lncRNA. Hematoxylin and eosin staining and pathological analysis were applied to evaluate the effects of Gm48853 mutations on embryonic/placental development. 5-Ethynyl-2&#39;-deoxyuridine (EdU) and terminal deoxynucleotidyl transferase deoxy-UTP-nick-end labeling assays were used to analyze the status of cell proliferation and apoptosis in Gm48853- deficient embryos and placentas. Results: PiggyBac (PB) transposon insertion into the intron of Gm48853 resulted in a significant decrease in Gm48853 expression and embryonic lethality at midgestation. Homozygous Gm48853 mutations led to severe growth retardation of embryos and impaired the morphogenesis of the placental labyrinth. In addition, cell proliferation was dramatically decreased in Gm48853PB/PB embryos and placentas, and apoptosis was radically increased in the mutant embryos but not in the mutant placentas. Conclusion: Antisense lncRNA Gm48853 may regulate embryonic/placental development by enhancing cell proliferation and/or inhibiting apoptosis. 


The messenger RNA and long non-coding RNA expression profiles in ectopic and eutopic endometrium provide novel insights into endometriosis
Song-Ping Liu, Xin Tian, Hong-Yan Cui, Qiong Zhang, Ke-Qin Hua

Reproductive and Developmental Medicine 2019 3(1):11-17

Objective: To establish the messenger RNA (mRNA) and long non-coding RNA (lncRNA) expression profiles in ectopic and eutopic endometrium and provide novel insights into endometriosis. Methods: The mRNA and lncRNA expression profiles were tested using high-throughput sequencing technology in ectopic and eutopic endometrium with endometriosis and normal endometrium without endometriosis. The potential targeted lncRNAs were annotated by analyzing the correlation between lncRNA and mRNA expression to better understand the pathogenesis of endometriosis. Results: In ectopic compared with normal endometrium, a total of 2,188 mRNAs and 1,200 lncRNAs were differentially expressed with a fold-change (FC) &#8805;2.5. In eutopic compared with normal endometrium, a total of 2,324 mRNAs and 695 lncRNAs were differentially expressed with an FC &#8805;1.5. In ectopic compared with eutopic endometrium, a total of 2,223 mRNAs and 511 lncRNAs were differentially expressed with an FC &#8805;2. Bioinformatic analysis indicated that the differentially expressed mRNAs were enriched in the biological processes and signaling pathways involved in endometriosis. In addition, we constructed a gene coexpression network based on the dysregulated lncRNAs in both ectopic endometrium and eutopic endometrium, combined with their coexpressed mRNAs to simulate the complex interactions. Conclusions: This study describes the first-to-integrate analysis of the differential expression profiles of mRNAs and lncRNAs, including analyses between ectopic and normal endometrium, eutopic and normal endometrium, and ectopic and eutopic endometrium, which provides new insights to investigate the pathogenesis of endometriosis and explore novel diagnostic biomarkers and therapeutic targets. 


LncRNA4667 is dispensable for spermatogenesis and fertility in mice
Yu-Bing Dai, Yu Lin, Ning Song, Fei Sun

Reproductive and Developmental Medicine 2019 3(1):18-23

Objective: Spermatogenesis is a complex process which is of vital importance for sexual reproduction. In many studies of spermatogenesis, the mRNAs, protein-coding genes, as well as small noncoding RNAs (ncRNAs) have been well characterized. However, there remain numerous questions despite previously characterized molecular mechanisms. Long ncRNAs (lncRNAs) are a relatively new addition to our knowledge of ncRNAs. Limited studies have examined the function of lncRNAs in spermatogenesis. Therefore, we selected a testis-specific lncRNA, lncRNA4667, to analyze its potential role in spermatogenesis and male fertility. Methods: In situ hybridization and quantitative reverse transcription polymerase chain reaction analyses were used to confirm testis-specific expression of lncRNA4667. LncRNA4667 knockout mice were generated using CRISPR/Cas9 technology. Histology, sperm counts, sperm motility, body parameters, and fertility were compared between wild-type and knockout mice (n &#61; 8/group). Results: Expression analysis showed that lncRNA4667 was testis specific and localized to round spermatids in seminiferous tubules of adult mouse testes. Mice homozygous for a null mutation of lncRNA4667 displayed normal spermatogenesis and fertility compared with wild-type mice. Conclusions: These data indicate that lncRNA4667 is dispensable for spermatogenesis and fertility in mice, and the localization of lncRNA4667 makes it a useful marker for the identification of round spermatids in mice.

Reproductive and Developmental Medicine 2019 3(1):24-29

Objective: To retrospectively investigate the clinicopathological characteristics of ovarian juvenile granulosa cell tumors (JGCTs) and to evaluate the safety of fertility-sparing surgery. Methods: In this study, surgically treated patients with JGCTs diagnosed between January 2004 and October 2018 in our center were identified. Clinicopathological data, survival outcomes, and recurrence rates were examined in these patients. Results: A total of 8 patients were included. All patients were premenarchal girls or young women (age range, 9&#8211;32 years). Irregular vaginal bleeding was the most common presenting symptom. Of them, seven patients were classified with Stage I JGCTs, and they underwent fertility-sparing surgery. One patient who had Stage IIIC JGCT and had completed childbearing underwent complete surgery. Seven patients received adjuvant chemotherapy. The median follow-up duration in the total cohort was 64 months (range, 2&#8211;117 months). The overall survival rate in the fertility-sparing group was 100&#37;, whereas the patient with Stage IIIC JGCT died 1 month after the treatment. Conclusions: Fertility-sparing surgery might not show a negative impact on oncologic outcomes. Fertility sparing could be considered a modified option for patients with Stage I JGCTs. However, due to the limited number of patients, the conclusion must be interpreted with caution, and larger or multicenter studies are needed before conclusions can be drawn.

Yun-Hui Tang, Xiao-Ying Yao

Reproductive and Developmental Medicine 2019 3(1):30-35

Objective: To study the safety of mifepristone on thyroid hormone level by using hyperthyroidism pregnant model in mouse to simulate the process of medical abortion and observe the changes of thyroid hormone during abortion. Methods: A total of 60 female Institute of Cancer Research (ICR) mice aged 6&#8211;8 weeks were divided into control group, control group with 0 mgRU486 group (control-0 mgRU486), control group with 2 mgRU486 group (control-2 mgRU486), hyperthyroid pregnant mice with 0 mgRU486 group (hyper-0 mgRU486), hyperthyroid pregnant mice with 2 mgRU486 group (hyper-2 mgRU486), and hyperthyroid pregnant mice with 20 mgRU486 group (hyper-20 mgRU486). In the hyperthyroidism groups, L-thyroxine sodium was intraperitoneally injected every day at 30 &#956;g&#183;kg&#8722;1&#183;day&#8722;1 until the end of the experiment. On the 7th day of the experiment, free triiodothyronine (FT3), free tetraiodothyroxine (FT4), thyroxine (TT4), and thyroid-stimulating hormone (TSH) levels were tested. The mice in the control groups and those in the experimental groups were paired with the male mice (2:1) on the 10th day of the experiment, and the caging was recorded. On the 8th day of pregnancy (day 8), pregnant mice were subcutaneously injected with mifepristone in different doses and were sacrificed 6 h later. Pregnancy rate and the number of embryos were recorded. Thyroid tissues were observed by hematoxylin and eosin (HE) staining. Serum TSH level was determined by radioimmunoassay. Results: Six hours after injection with mifepristone, serum FT3, FT4, and TT4 levels of pregnant mice were all increased. The increased levels in the mice under hyperthyroidism were different from those in the control groups (P &#60; 0.05). There was no difference in the embryo number and pregnancy rate between the experimental and the control groups; HE staining indicated that there was no significant change in microscopic features before and after mifepristone administration. Conclusion: Serum thyroid hormone level of mice under hyperthyroidism was significantly increased after mifepristone administration. Therefore, mifepristone should be avoided when hyperthyroidism has not been controlled.

Yun Yang, Jia-Po Li, Yue Bian, Gui-Yu Song, Yuan-Yuan Li, Dong-Ying Zheng, Ling Huang, Chong Qiao

Reproductive and Developmental Medicine 2019 3(1):36-41

Objective: Preeclampsia (PE) is a serious complication of pregnancy. Placental ischemia could be an initiating event, but the molecular mechanisms underlying PE are unclear. Lin28B, a paralog of Lin28 RNA-binding protein, is predominantly expressed in human placenta, and decreased Lin28B expression may play a role in PE by reducing trophoblast invasion. The current study was intended to verify whether Lin28B plays a role in the pathogenesis of PE in rat model for reduced uterine perfusion pressure (RUPP). Methods: We used RUPP rat model. The changes in blood pressure, 24-h urine protein excretion, and fetal development in RUPP rats were recorded and compared to those of normal pregnant (NP) rats. Furthermore, the expression of Lin28B mRNA and protein in placenta was determined using quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemistry. Results: The blood pressure, 24-h urine protein excretion, and embryo absorption rate were significantly increased in RUPP rats on the 20th day of gestational period compared with the NP rats (P &#60; 0.001). However, there was no difference in the weight of placenta in RUPP versus NP rats (P &#62; 0.05). The expression levels of Lin28B mRNA and protein in the placenta of RUPP rats were also significantly decreased in comparison to NP rats (P &#60; 0.001). Conclusion: Our results show that the expression of Lin28B in the placenta of RUPP rats is different from that in NP rats, thus suggesting a role of Lin28B in the pathogenesis of preeclampsia.

Ji-Jun Hu, Jia-Xin Li, Xing-Ling Wang, Yi-Chun Guan, Li-Jun Sun

Reproductive and Developmental Medicine 2019 3(1):42-48

Objective: To investigate the effects of exogenous &#945;-linolenic acid (ALA) on in vitro maturation (IVM) and developmental competence of human oocytes. Methods: Experiment 1 examined the effects of ALA at different concentrations (0 [control], 10, 50, 100, and 200 &#956;mol/L) in the IVM medium on oocyte maturation. Treatment with 50 &#956;mol/L ALA significantly accelerated oocyte maturation (P &#60; 0.05) and resulted in significantly higher mitochondrial DNA (mtDNA) copy number compared to the control. Hence, 50 &#956;mol/L ALA was selected for combination with follicular fluid (FF) to investigate oocyte developmental potential. mtDNA of the matured oocyte was analyzed by real-time polymerase chain reaction. Experiment 2 investigated the effects of FF with optimal ALA concentration (Group A: ALA &#43; FF &#43; IVM medium) or without ALA (Group B: FF &#43; IVM medium) on oocyte maturation, fertilization, 2 pronuclear cleavage, and embryo and blastocyst development. Malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were measured for maturation medium from Group A, Group B, and Group C (control group, IVM medium only). Results: Treatment with 50 &#956;mol/L ALA obviously accelerated oocyte maturation (P &#60; 0.05) and resulted in significantly higher mtDNA copy number (P &#60; 0.05) in the matured oocytes compared to the control (0 &#956;mol/L ALA). Supplementation of 50 &#956;mol/L ALA and FF (Group A) obviously increased the total maturation rate than FF-treated group (Group B) which has higher (P &#60; 0.05) total maturation rate than that of Group C. However, no significant differences were observed in fertilization, embryo availability, and blastocyst production among Group A, B, and C. Treatment with 50 &#956;mol/L ALA decreased the level of MDA (P &#60; 0.05), but had no effect on the activity of SOD in the IVM medium. Conclusions: Our results suggested that the treatment with 50 &#956;mol/L ALA during IVM improves maturation in human oocytes. It is also likely to improve embryo availability and blastocyst formation. This might be associated with the alteration of mtDNA replication (increased mtDNA copy number) and the reduction of oxidative stress (reduced MDA level).

Jun-Yi Yang, He Li, Nan Lu, Lu Li, Xiao-Xi Sun

Reproductive and Developmental Medicine 2019 3(1):49-53

Objective: To evaluate the effect of recombinant human growth hormone (rhGH) supplementation during hormone-replacement therapy and frozen-thawed embryo transfer (FET) in patients with thin endometrium. Methods: A retrospective research was conducted on 225 patients, who underwent artificial cycle FET in Shanghai, China, between January 2016 and November 2017. Data from 245 FET cycles were analyzed, of which 184 cycles received rhGH (GH group) and 61 did not (control group). Results: Clinical pregnancy and implantation rates were significantly higher in the GH group than those in the control group (64.7&#37; vs. 49.2&#37;, P &#61; 0.032; 44.8&#37; vs. 32.8&#37;, P &#61; 0.019, respectively). After logistic regression analysis, rhGH was considered the only significant variable that influenced clinical pregnancy rate, increasing it by 1.89-fold. On the other hand, the presence of rhGH did not seem to affect the early pregnancy loss. Conclusions: Our results indicated that simultaneous addition of rhGH could improve clinical outcomes of FET in patients with thin endometrium, particularly in patients between 30 and 34 years of age.

Objective: To investigate the spectrum of diseases in female children and adolescents hospitalized for obstetric and gynecological conditions. Methods: This retrospective study included patients (age &#8804;19 years) admitted to the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, between January 2003 and December 2017. Their medical records &#8211; age, principal diagnosis, and treatment &#8211; were reviewed and analyzed. Diagnoses were divided into eight disease classifications. Comparison between groups was analyzed with Student&#39;s t-test. Results: This study enrolled 4,628 inpatients. The number of inpatients increased each year, especially in the groups of gynecologic tumors, pregnancy-related conditions, and disorders of the breast. The mean age was 16.33 &#177; 2.42 years (range: 2&#8211;19 years). Of all the inpatients, 41.9&#37; (n &#61; 1,939) were hospitalized for gynecologic tumors, and 85.5&#37; (n &#61; 1,657) of the tumors were benign. Altogether, ovarian cysts (28.66&#37;, n &#61; 1,325) were the most common disease observed in this group. In addition, 32.9&#37; (n &#61; 1,524) of the inpatients were hospitalized for pregnancy, childbirth, and puerperium; within this group, 21.9&#37; (n &#61; 1,014) were hospitalized for artificial abortions. Conclusions: The efforts of all stakeholders toward the implementation of government policies to promote sexual and reproductive health among children and adolescents in China have been effective.

Neha Maheshwari, Shefali Gautam, Rajni Kapoor, Ravi Prakash, Shobhna Jafa, Rajni Gupta

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):9-13

Background: Various techniques of central neuraxial blockade have been tried and successfully used for caesarean section surgeries. Nowadays it is must and essential to know the possible effective dose of clonidine to overcome its known side effect like bradycardia, hypotension and sedation for better outcome of mother as well as foetus in lower segment caesarean section. We have conducted such study to compare different doses of clonidine as an adjuvant to intrathecal isobaric levobupivacaine. The plain levobupivacaine has been shown to truly isobaric with respect to CSF of pregnant women and this property got advantage over hyperbaric bupivacaine in its predictable spread. Materials and Methods: There were about 90 cases of emergency caesarean section of more than 37 weeks gestation with ASA physical status class 2 under spinal anaesthesia were randomly divided into three groups of 30 patients each. In all groups we assessed onset, two segment regression and requirement of analgesic in post-operative period, level of motor block by modified bromage scale [Table 1] and sedation by Campbell sedation score [Table 2]. Maternal and foetal hemodynamic was monitored as well. Group A (n &#61; 30) 10 mg of 0.5&#37; (2 ml) isobaric levobupivacaine &#43; 15 mcg clonidine (0.5 ml). Group B (n &#61; 30) 10 mg of 0.5&#37; (2 ml) isobaric levobupivacaine &#43; 30 mcg clonidine (0.5 ml). Group C (n &#61; 30) 10 mg of 0.5&#37; (2 ml) isobaric levobupivacaine &#43; 45 mcg clonidine (0.5 ml). Normal saline was used to make volume of clonidine upto 0.5 ml. Result: Onset of sensory block was highest in group A with significant difference (P value &#60;0.0001) in all three groups. Two segment regression time (in minutes) was highest in group C with significant difference (P value &#60;0.0001) in all three groups. There was fall in systolic blood pressure (SBP) &#60;80&#37; of baseline was found in 0 (0.00&#37;), 10 (33.33&#37;) and 22 (73.33&#37;) patients in group A, B and C respectively while fall in HR &#60;80&#37; of baseline was found in 0 (0.00&#37;), 1 (3.33&#37;) and 19 (63.33&#37;) patients. Sedation score was 1 in 30 (100&#37;) patients in group A, it was 1 in 10 (33.33&#37;), 2 in 20 (66.67&#37;) in group B while it was 1 in 5 (16.77&#37;), 2 in 10 (33.33&#37;) and 3 in 15 (50&#37;) patients in group C. Conclusion: Spinal anaesthesia performed with isobaric 0.5&#37; levobupivacaine with 30 mcg clonidine (Group B) provides better haemodynamic stability, early onset of sensory and motor blockade, decreased requirement of post-operative analgesia.

Anila K Kalliyath, Sara V Korula, Anna Mathew, Saramma P Abraham, Mini Isac

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):14-17

Background: Preoperative anxiety is a common problem in all patients. The reason could be incomplete information regarding the anesthesia and surgical procedure. Cesarean section (CS) is a common surgery and treatment of postoperative pain after CS continues to be an ongoing challenge. Aim: The present study was carried out to assess if preoperative education with a handout about spinal anesthesia can reduce anxiety and postoperative pain in parturients undergoing CS under spinal anesthesia. Methods and Materials: We randomized 64 parturients into two equal groups; study (Group A) and control group (Group B). The study group was given a handout and a structured education about spinal anesthesia. The control group was given routine preoperative information. The Amsterdam preoperative anxiety and information scale (APAIS) was used to measure anxiety preoperatively and visual analogue scale (VAS) for pain at 5 h and 24 h postoperatively. Statistical Analysis: The two groups were compared using Student&#39;s t test and non-parametric Wilcoxon-Mann-Whitney U test. Result: The median difference in preoperative anxiety scores (APAIS) in the two groups was found to be 8.00 (P &#60; 0.001), which was significant statistically. The median value of postoperative pain analyzed using VAS after giving education, at 5 h was significantly reduced in Group A (5.00) as compared to Group B (9.00). The median value of VAS score at 24 h was significantly different in both groups. It was 1.0 in Group A, whereas the same was 5.50 in Group B (P &#60;.00). The median difference in hours in the duration of analgesia between the two groups was 0.62, which was not significant statistically (P &#60; 0.10). Conclusion: A planned preoperative education and handout with details about spinal anesthesia can have a significant impact on reducing the preoperative anxiety and the postoperative pain in parturients undergoing elective CS under spinal anesthesia. 


I-gel for day care diagnostic laparoscopic gynecological surgery: A comparison of two regimes of IV propofol with dexmedetomidine or butorphanol
Alka Chhabra, Apoorva Gupta, Shashank Gupta, Kunal Chauhan, Sunanda Gupta

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):18-23

Background: Insertion of I-gel requires adequate depth of anesthesia and jaw relaxation in an unparalyzed patient. Propofol with adjuvants is commonly used to facilitate I-gel insertion. This study was conducted to compare ease of insertion by addition of either dexmedetomidine or butorphanol added to propofol for insertion of I-gel in gynecological laparoscopic surgeries. Materials and Methods: About 120 female patients, the American Society of Anesthesiologists (ASA) Grade I&#8211;II, 18&#8211;40 years, and body mass index (BMI) &#60;30 kg/m2 were allocated randomly either to receive dexmedetomidine 0.5 mcg/kg IV (Group I) or butorphanol 0.02 mg/kg IV (Group II). Ease of insertion score was determined by jaw mobility grading, number of attempts, need of manipulation, limb movement and bucking, use of laryngoscope and muscle relaxant, and time taken for insertion. Adverse events like expiratory stridor, lacrimation, breath holding, and audible air leak after insertion were also noted. Intraoperative monitoring included heart rate (HR), mean arterial pressure (MAP), and oxygen saturation at 0&#8211;15 min of I-gel insertion. Post-operative side effects like coughing, laryngospasm, hiccups, and sedation were also noted. Results: The efficacy of successful insertion of I-gel was significantly higher in propofol-dexmedetomidine (Group I) as compared to propofol&#8211;butorphanol (Group II) (P &#60; 0.001). Significant fall in HR from baseline to 15 min after I-gel insertion (88.65 &#177; 14.84 to 71.90 &#177; 12.15 bpm) was found in Group I as compared to Group II (87.60 &#177; 12.71 to 83.52 &#177; 10.91 bpm, P &#60; 0.001). There was a fall in MAP from baseline values after induction upto 15 min following insertion in Group I (96.72 &#177; 13.54 to 86.96 &#177; 11.03), while in Group II fall in MAP from baseline was observed only upto 1 and 2 min of I-gel insertion (96.27 &#177; 9.53 to 89.42 &#177; 9.03) (P &#60; 0.001). Conclusion: Addition of dexmedetomidine to propofol provided significantly better insertion characteristics for I-gel and adequate hemodynamic stability with minimal complications compared to butorphanol.

Neena Jain, Pooja R Mathur, Poorva Soni, Veena Patodi, Surendra K Sethi, Veena Mathur

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):24-29

Context: Adjuvants may be added to decrease motor blockade caused by intrathecal bupivacaine and prolong labor analgesia. Aim: To study the effect of intrathecal dexmedetomidine versus fentanyl when added to bupivacaine on the duration of labor analgesia, progress of labor, block characteristics, and side effects. Settings and Design: A prospective, randomized double-blind study. Materials and Methods: Sixty parturients consenting for labor analgesia were divided into two groups. Group A (n &#61; 30) received an intrathecal 0.5&#37; hyperbaric bupivacaine 2.5 mg and dexmedetomidine 5 &#956;g and Group B (n &#61; 30) received an intrathecal 0.5&#37; hyperbaric bupivacaine 2.5 mg and fentanyl 25 &#956;g. Partogram, visual analog score, sensory and motor blockage, progress of labor, maternal hemodynamic variations, and fetal heart rate were noted. Statistical Analysis Used: Standard qualitative and quantitative tests were used to compare data (e.g., unpaired student t-test, ANOVA, Chi-square); P value of 0.05 was considered significant. Results: Duration of labor analgesia was significantly greater in Group A as compared to Group B (254.17 &#177; 4.75 min vs. 123.67 &#177; 6.01 min, P &#60; 0.0001). Mean onset of analgesia was earlier in Group A as compared to Group B (1.27 &#177; 0.37 min vs. 3.27 &#177; 0.37 min, P &#60; 0.0001). Duration of the active phase of the first and second stages of labor, rate of cervical dilation, hemodynamic and side effects profile, and neonatal outcome were comparable in both groups (P &#62; 0.05).

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):30-34

Background:&#8220;Saving Mothers Score&#8221; (SMS) was developed and validated as a comprehensive obstetric score for identification of sick mothers. This study aimed to evaluate the efficacy of the SMS chart to predict maternal morbidity and improve maternal and fetal outcomes. Materials and Methods: A single-center randomized study was done on 700 subjects of two groups from February 2017 to 2018. The subjects were treated as per the existing hospital norms in Group A (n &#61; 360) and SMS chart was used in addition to the hospital norms in Group B (n &#61; 340). Results: Demographic data, preterm deliveries, and cesarean delivery rate were not significantly different in both groups. Postpartum hemorrhage was significantly more in Group A when compared with Group B where SMS chart was used (unadjusted odds ratio 3.22, 95&#37; confidence interval: 1.59, 6.97, P &#61; 0.0004). The overall morbidity was higher (P &#61; 0.0001) in Group A. The mean hospital stay was longer in Group A (P &#61; 0.0001). Neonatal morbidity was 14.4&#37; in Group A and 10.3&#37; in Group B (P &#61; 0.169). APACHE II (mean 10.87, range 0&#8211;18) and SOFA (mean 7.75, range 0&#8211;12) scores were determined along with SMS (mean 18.87, range 5&#8211;26) in eight critically ill parturients. There was no maternal mortality in this series. Conclusion: SMS predicts maternal morbidity and can help initiation of appropriate treatment to improve maternal and hence fetal outcome. Multicentric studies are needed for further evaluation and comparison of SMS to APACHE II and SOFA scores.

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):35-39

Context: Intraoperative hypothermia is a leading cause of morbidity in the perioperative period. This retrospective audit study was planned to assess the efficacy of three different active warming devices used in maintaining euthermia in patients who underwent lower segment cesarean section (LSCS). Aims: Audit of the three different fluid warming techniques in maintaining euthermia in patients who underwent cesarean sections. Settings and Design: A retrospective audit. Materials and Methods: In total, 698 patients were included in the study who underwent LSCS and were divided on the basis of the warming technique used into Group 1 (n &#61; 241, blood warming bath), Group 2 (n &#61; 238, cabinet), and Group 3 (n &#61; 219, inline warmer). The preoperative core body temperature was compared in each group with the intraoperative body temperature as well as with core body temperature measured 20 minutes after shifting the patient in the postoperative room as per the entries made in the central anesthesia registry. The incidence of the shivering was also noted from the data for each group separately. Statistical Analysis Used: One-way analysis of variance was applied for comparing the mean (SD) between the three groups and unpaired t-test was used to compare two mean (SD) values.P value &#60;0.05 was considered significant. Results: Comparison of preoperative core body temperature (T0) with intraoperative (T1, T2) and postoperative (T3) temperatures within the groups showed significant results in Group 1 (blood warming bath), demonstrating its inefficiency in maintaining euthermia in the perioperative period. Conclusions: Cabinet and inline fluid warmer prove to be efficacious in maintaining euthermia and limiting shivering in the patients for cesarean section. 


Mallory-Weiss Syndrome complicating pregnancy – A rare near miss
Isha Chopra, Sunil T Pandya, Mangalampally Kiran Kumar, Surapaneni Tarakeswari, Hemamalini , Madapu Manokanth, Prabhakar Boddu

Journal of Obstetric Anaesthesia and Critical Care 2019 9(1):40-42

Mallory-Weiss syndrome (MWS) rarely occurs during pregnancy and can lead to massive bleed if occurring in the third trimester. Unrecognized MWS may lead to life threatening hemorrhage and shock affecting maternal and fetal well-being. We describe a rare case of MWS in a pregnant patient at 36 weeks of gestation with underlying pre-eclampsia, acute kidney injury, and hemodynamic instability. The possibility of mucosal tears should be kept in mind in the absence of an obvious source of bleeding.
