Vaginal Progesterone Has No Diabetogenic Potential in Twin Pregnancies: A Retrospective Case-Control Study on 1686 Pregnancies

Background: In this study, we aimed to investigate the incidence of gestational diabetes mellitus (GDM) in women who carried twin pregnancies and received vaginal progesterone. Methods: In this retrospective cohort study, 203 out of 1686 women with twin pregnancies received natural progesterone (200 mg/day between gestational weeks 16 + 0 and 36 + 0) vaginally for ≥ 4 weeks. The control group consisted of 1483 women with twin pregnancies without progesterone administration. Pearson’s Chi squared test, Fisher’s exact test, and Student’s t-test was used to compare differences between the control and the progesterone-treated groups. A multivariate binary logistic regression was performed to assess relative independent associations on the dependent outcome of GDM incidence. Results: Vaginal progesterone treatment in twin pregnancies had no significant influence on developing GDM (p = 0.662). Higher pre-pregnancy BMI (OR 1.1; p < 0.001), GDM in previous pregnancy (OR 6.0; p < 0.001), and smoking during pregnancy (OR 1.6; p = 0.014) posed an increased risk for developing GDM. Conclusion: In twin pregnancies, the use of vaginal progesterone for the prevention of recurrent preterm delivery was not associated with an increased risk of GDM.

Intravesical prostaglandin E2 is effective in the recovery of spontaneous voiding after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. The aim of the study was to compare the effects of intravesical prostaglandin E2 in the prevention of urinary retention after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. STUDY DESIGN: From November 1996 to June 1999 fifty women underwent the Lahodny procedure for moderate/severe cystocele and stress urinary incontinence. Women were randomly assigned to 1 of the 2 study groups: intravesical prostaglandin E2 versus controls. Data obtained were analyzed with the Student t test and the Fisher exact test. RESULTS: Two patients of the treatment group had to be excluded from the study, one because of the wrong measurement of the post-voidal residual volume and another due to a fastidious burning sensation which appeared immediately after prostaglandin instillation and required the suspension of the treatment. No other side effects such as nausea, vomiting, diarrhea or hyperthermia were observed. Patients who underwent the prostaglandin E2 treatment showed a recovery of spontaneous voiding after 7.9±6.7 days, whereas this interval was significantly longer in the control group, being 12.9±9.7 days (p=0.04, Two tailed Unpaired Student's T test). CONCLUSION: The effectiveness and the low associated morbidity mark the treatment with intravesical prostaglandin E2 useful in the recovery of normal voiding after transvaginal pubocervical fascia reconstruction and short arm sling with the procedure according to Lahodny.

We evaluated the association between prostate cancer non-coding RNA 1 (PRNCR1) polymorphisms and the risk of developing gastric cancer (GC) and GC subgroups in Korea. A case–control study was conducted with 437 GC patients and 357 healthy controls using a TaqMan genotyping assay. A chi-squared test, binary logistic regression, and genetic models were used to explore the association between five PRNCR1 polymorphisms and GC risk. After adjusting for gender and age, overall analyses using the recessive model indicated that the rs13252298 GG genotype was significantly associated with increased risk of intestinal-type gastric cancer (IGC). In the stratification analyses, the recessive model indicated that the rs1016343 TT genotype was significantly associated with decreased GC risk in individuals aged <60 years showing lymph node metastasis (LNM)-negative results. The rs13252298 GG genotype in the recessive model showed increased GC risk in subjects aged ≥60 years showing LNM-positive results and those aged ≥60 years in tumor stage III. In the dominant model, the rs16901946 combined genotype (AG/GG) was significantly associated with increased GC risk in subjects aged <60 years with tumor stage III. In the recessive model, the rs16901946 GG genotype was associated with decreased risk of GC and IGC in males aged ≥60 years. Thus, genetic variations in PRNCR1 may contribute to susceptibility to GC.

AbstractIntroduction:Severe trauma can lead to amputation of limbs. There is no golden standard or comprehensive evaluation indicator for amputation. It is difficult for the primary rescue organization to focus on the most essential indicators and to determine whether to perform amputation or take proper operation.Problem:For medical staff in first-line medical teams for disaster relief or in a common primary hospital, what indicators should they focus on to keep the patient’s limbs when they receive wounded patients with severe trauma?Methods:A retrospective case-control study was performed based on the patients with severe trauma from January 2013 through December 2018 in the emergency department of Southwest Hospital (Shapingba District, Chongqing, China), a Level I trauma center. A total of 165 cases were divided into amputation group (n = 79) and non-amputation control group (n = 86), which had severe skin and muscle injury but without amputation. The causes of trauma and the special cases were analyzed. Binary logistic regression models were used to find the essential indicators for amputation.Conclusions:Neurovascular injury with delayed treatment was the most decisive indicator leading to amputation, and time phase was also important for limb salvage. Preliminary treatment of disaster victims and patients with severe trauma should focus on neurovascular status and timely delivery.

Abstract Background: Trial of labor after cesarean (TOLAC) is a viable option for safe delivery. In some cases cervical ripening and subsequent labor induction is necessary. However, the commonly used prostaglandins are not licensed in this subgroup of patients and are associated with an increased risk of uterine rupture. Methods: This cohort study compares maternal and neonatal outcomes of TOLAC in women (n=82) requiring cervical ripening agents (osmotic dilator vs. prostaglandins). The initial Bishop scores (BSs) were 2 (0–5) and 3 (0–5) (osmotic dilator and prostaglandin group, respectively). In this retrospective analysis, Fisher’s exact test, the Kruskal-Wallis rank sum test and Pearson’s chi-squared test were utilized. Results: Vaginal birth rate (including operative delivery) was 55% (18/33) in the osmotic dilator group vs. 51% (25/49) in the dinoprostone group (P 0.886). Between 97% and 92% (32/33 and 45/49) (100%, 100%) of neonates had an Apgar score of >8 after 1 min (5, 10 min, respectively). The time between administration of the agent and onset of labor was 36 and 17.1 h (mean, Dilapan-S® group, dinoprostone group, respectively). Time from onset of labor to delivery was similar in both groups with 4.4 and 4.9 h (mean, Dilapan-S® group, dinoprostone group, respectively). Patients receiving cervical ripening with Dilapan-S® required oxytocin in 97% (32/33) of cases. Some patients presented with spontaneous onset of labor, mostly in the dinoprostone group (24/49, 49%). Amniotomy was performed in 64% and 49% (21/33 and 24/49) of cases (Dilapan-S® group and dinoprostone group, respectively). Conclusions: This pilot study examines the application of an osmotic dilator for cervical ripening to promote vaginal delivery in women who previously delivered via cesarean section. In our experience, the osmotic dilator gives obstetricians a chance to perform induction of labor in these women.

Background Few studies exist about risk factors for complications in subsequent biopsies. Purpose To explore risk factors for complications in initial versus subsequent biopsies in native and transplant kidneys, which may predict biopsy complications. Material and Methods In a multicenter study, 2830 native kidney biopsies (4.3% subsequent) were analyzed for major complications (1251 of these were also analyzed for minor) and 667 transplant kidney biopsies (29% subsequent) were analyzed for major and minor complications. No death or nephrectomy were described. Fisher’s exact test, Student’s t-test, chi-square analyses, and univariate and multiple binary logistic regression analyses were employed; P < 0.05 was considered significant. Results In initial native kidney biopsies, the frequency of major complications was higher in women compared to men (odds ratio 1.6, 95% confidence interval 1.1–2.2), in younger patients (50 vs. 54 years, P = 0.007), and in patients with lower weight (78 vs. 82 kg, P = 0.005). In subsequent native kidney biopsies, patients with major complications had a higher systolic blood pressure (145 vs. 132 mmHg, P = 0.03). In initial transplant kidney biopsies, biopsies with major complications had less glomeruli in the biopsy (17 vs. 24, P = 0.046). In subsequent transplant kidney biopsies, patients with major complications had a higher mean arterial pressure (112 vs. 98 mmHg, P = 0.002). In subsequent native kidney biopsies, there was a higher number of SLE-nephritis (12% vs. 4.6%, P = 0.001) compared to initial biopsies. Conclusion The different types of risk factors for complications in initial versus subsequent renal biopsies could be important for the clinicians to improve patients’ safety.

Our objective was to estimate the effect of therapeutic hypothermia on platelet count in neonates after perinatal asphyxia. We performed a retrospective case control study of all (near-) term neonates with perinatal asphyxia admitted between 2004 and 2012 to our neonatal intensive care unit. All neonates treated with therapeutic hypothermia were included in this study (hypothermia group) and compared with a historic control group of neonates with perinatal asphyxia treated before introduction of therapeutic hypothermia (2008). Primary outcome was thrombocytopenia during the first week after birth. Thrombocytopenia was found significantly more often in the hypothermia group than in the control group, 80% (43/54) versus 59% (27/46) (P=.02). The lowest mean platelet count in the hypothermia group and control group was97×109/Land125×109/L(P=.06), respectively, and was reached at a mean age of 4.1 days in the hypothermia group and 2.9 days in the control group (P<.001). The incidence of moderate/severe cerebral hemorrhage was 6% (3/47) in the hypothermia group versus 9% (3/35) in the control group (P=.64). In conclusion, neonates with perinatal asphyxia treated with therapeutic hypothermia are at increased risk of thrombocytopenia, without increased risk of cerebral hemorrhage.

Adverse Pregnancy

Objective: Pregnancies after in vitro fertilization (IVF) are associated with a less favorable outcome compared to natural conception as consistently shown in various studies. However, etiologic factors behind this issue remain to be elucidated. We aimed to demonstrate whether the etiology of infertility has a role on poor pregnancy outcomes in IVF pregnancies. Methods: In this retrospective case control study; IVF and spontaneous singleton pregnancies were investigated. The infertile patients were divided into six groups according to the etiology of their infertility (anovulation, male factor, tubal factor, endometriosis, unexplained infertility and poor ovarian reserve). The incidence of preeclampsia, gestational diabetes mellitus, intrahepatic cholestasis of pregnancy, preterm birth and birth weight discrepancies was examined between the groups and subgroups. After adjusting the confounding variables for each infertility subgroup such as demographic data, embryo stage in transfer (blastocyst against cleavage stage) and fresh and frozen embryo transfer status, the effect on pregnancy outcomes was investigated using multinomial logistic regression analysis. Results: The study included 934 patients in the IVF group and 1009 patients in the control group. While adverse pregnancy outcomes were more frequent in the general infertility group in comparison to the control group, after elimination of the confounding variables, the direct effect of the etiology of infertility on these outcomes could not be shown. Conclusion: In the IVF pregnancies, most of the increased risk of poor pregnancy outcomes appeared to be explained by maternal characteristics (such as age, body mass index) and by treatment protocols rather than infertility etiology. Physicians should consider these risks while counselling patients.

BACKGROUND: The second leading cause of cancer-related death in women is breast cancer. Xenobiotic Metabolizing Enzymes (XMEs) contribute to the detoxification of numerous cancer therapy-induced products. In the metabolism of xenobiotic, cytochrome P450s or monooxygenases perform an important function by catalysing the hydroxylation reaction. In this study, the susceptibility and genetic polymorphisms of CYP450 isoenzymes was investigated that may have an etiological role in breast cancer. AIM: The main purpose of this study was to evaluate the association of CYP1A1 (rs4646421), CYP1B1 (rs1056836), CYP2C8 (rs1058930), and CYP19A1 (rs749292) polymorphisms with the risk of breast cancer in Mazandaran province. MATERIAL AND METHODS: This cross-sectional case-control study were recruited 72 patients and 51 healthy individuals and was performed between March 2018 to May 2018 in the Oncology Department at Imam Hospital in Sari city, Iran. Peripheral blood samples were collected in EDTA tube, and DNA extraction was performed using the salting-out method and WizPrep extraction kits. Breast cancer patients with known clinicopathological characters and healthy women as control group were genotyped for genes polymorphisms by PCR-RFLP technique, using restriction enzymes. Chi-square, Fisher exact test and Logistic regression model, were applied for statistical analysis. RESULTS: The results of the experiments showed that there was a significant relationship between two groups and the age of the patients is significantly higher than the control group (p = 0.044). According to the chi-square and Fisher exact test, education, pregnancy, menopause status and oppose were significant between the two groups. Based on using a logistic regression model in two normalized and age-adjusted models to finding relationship between the genotypes of each gene and breast cancer risk, it was determined that in the CYP2C8 genotype, those who have the CG allele have a 7.74 degree increased risk of breast cancer (CI = 95% 0.95-62.5) and in the CYP19A1 gene, individuals with GA genotype, increased risk of breast cancer (CI = %95 1.52-27.21), about the CYP1B1 gene, people with two genotypes of CG + GG had higher risk of breast cancer (CI = %95 1.19-5.71) and allele G has decreased risk of breast cancer in this gene (P = 0.0271), also allele G in CYP2C8 gene had the protective effect (P = 0.02). In the age-adjusted model, for the CYP2C8 gene, GG genotype increased risk of breast cancer (CI = %95 1.11-75.84) as well as, the CG + GG genotype in CYP1B1 gene (CI = %95 1.31-6.57). CONCLUSION: Our results confirm the association between CYP2C8 (rs1058930), CYP19A1 (rs749292) and CYP1B1 (rs1056836) gene polymorphisms and increased risk of breast cancer in women in Mazandaran province.

Multifetal Pregnancy

ABSTRACT An adverse consequence of the widespread introduction of assisted reproductive techniques has been an exponential increase in the prevalence of multifetal pregnancies (Botting et al 1987). Such pregnancies are associated with increased risk of miscarriage and perinatal death (Kiely et al 1992). One of the options in the management of multifetal pregnancies is embryo reduction to twins which is associated with a reduction in the background risk of adverse pregnancy outcome (Evans et al 1995). The aim of the study was to compare the gestation at delivery and birth weight of surviving twins following multifetal pregnancy reduction to those in a control group of dichorionic non-reduced twins. Materials and methods A case control study evaluating pregnancy outcomes post embryo reduction. Study takes into account all patients with successful day three embryo transfers resulting in multifetal pregnancy. First trimester embryo reduction was carried out by intracardiac injection of KCl. Results A total of 26 multifetal pregnancies were reduced to twins at early gestational age (7-9 weeks). Two cases (7.6%) of miscarriage, no cases of chorioamnionitis and five cases (19.2%) of transient spotting were recorded as postoperative complications. There was no vanishing of embryos in those reduced to twins. A total of 24 patients (92.3%) with twin pregnancies took home at least one baby, while 18 (69.23%) of these took both babies home. This was analyzed and compared with a control group of women with nonreduced twins pregnancies. The preterm delivery rate (defined as fetuses delivered before 37 weeks) in twin pregnancies was 53.8% (n = 14), with a severe preterm rate (defined as fetuses delivered before 32 weeks) of 23.07% (n = 6). One case (1.92%) of stillbirth occurred. The perinatal mortality rate was 13.46% (n = 6 newborns, and a 33-week stillbirth), mainly due to severe preterm labor. The latter group included no registered cases of newborns with congenital malformations. A total of 24 patients (92.3%) with twin pregnancies took home at least one baby, while 18 (69.23%) of these took both babies home. In two of the 26 multifetal pregnancies reduced to twins there was miscarriage of both fetuses before 24 weeks of gestation the median interval between reduction and multifetal loss was 5 weeks. In pregnancy reduced to twins as compared to nonreduced twins the percentage of miscarriage was slightly higher, but not statistically significant (7.6% compared to 6.9%, 0.07 × 2, P 0.8). The median gestation at delivery was lower (33.3 ± 9.2 compared to 35.67 ± 5.84 weeks, 2.26 > 2.0 t, 0.05 P) and the median weight deficit was greater (1.58 ± 0.96 compared to 1.92 ± 0.89 (4.04 > 3.37 t, 0.001 P).

Abstract Objectives: The present study assessed the risk factors for cytomegalovirus (CMV) corneal infection and compared the odds ratios.Methods: This study was a retrospective case-control study (2014.12–2021.1) over a 6-year period. We reviewed the medical record data and compared the differences between the CMV-positive and virus-negative groups with regard to sex, age, first diagnosis, and ocular complications to identify factors that may be associated with CMV corneal infections. The risk factors for CMV corneal infection were analysed using the chi-squared test and binary logistic regression models.Results: Ninety CMV-positive cases and 151 virus-negative controls were involved in this study. The risk factors for CMV corneal infection were Stevens-Johnson syndrome ocular complication (OR 12.851, 95%CI, 1.435–111.111; P=0.000), a penetrating keratoplasty (PKP) (OR 4.950, 95%CI, 2.632–9.346; P=0.024, and an anterior lamellar keratoplasty (DALK) (OR 5.290, 95%CI, 1.250–22.222; P=0.022).Conclusion: Severe corneal damage (PKP or DALK) and a severe corneal inflammatory response (SJS ocular complication) may be risk factors for CMV corneal infections.
