Association between preterm labour and pelvic floor muscle function.

We hypothesised that the pressure on the cervix increases with advancing gestation and it may lead to a cervical shortening and cause preterm labour in women with weak pelvic floor muscles. The aim of this prospective study was to measure vaginal resting pressure and pelvic floor muscle strength in the first trimester of pregnancy and to investigate their effects on labour. A study was conducted on the pregnant women with a low risk for preterm birth. The pelvic floor muscle strength and vaginal resting pressure were assessed in 320 pregnant women at their first trimester with a vaginal pressure measurement device. Fifty-two pregnant women were hospitalised for tocolytic therapy because of spontaneous preterm labour. Thirty-two of them (10.2%) had a preterm delivery despite the tocolytic therapy. Both the vaginal resting pressure (p = .009, 95%CI: 0.8; 5.9) and the pelvic floor muscle strength (p = .01, 95%CI: 3.5; 13.1) were significantly lower in the women with a preterm labour. Impact statement What is already known on this subject? The pelvic floor muscles have an essential role in continence and provide support to the pelvic organs. They also have an impact on labour. The pelvic floor muscles should distend to allow the passage of the foetus during labour. The rotation and flexion of the foetal head is due to the pelvic floor resistance. The effect of a vaginal birth on the pelvic floor's function is readily understood. On the other hand, the effect of the pelvic floor muscle function on labour is still controversial. What do the results of this study add? This prospective study showed that there is a negative association between the pelvic floor muscle strength and preterm labour. This is the first clinical study indicating that weak pelvic floor muscles may cause a preterm labour. What are the implications of these findings for clinical practice and/or further research? Pelvic floor physical therapy may be an alternative preventive strategy to reduce the risk of a spontaneous preterm birth.

Occult inflammation and/or ischemia may be responsible for the false positivity of biochemical Down syndrome screening test.

OBJECTIVE: To determine the possible underlying cause of a false-positive first or second trimester biochemical Down syndrome screening test result by means of second trimester amniotic fluid cytokine level analysis. METHODS: A total of 74 consecutive patients undergoing amniocentesis for karyotype analysis at 16-20 weeks' gestation were included in this prospective age-matched case-control study. The study group (n=38) had abnormal first or second trimester screening test results and normal karyotype results, while controls (n=36) included those admitted for genetic amniocentesis for other reasons who had normal first or second trimester screening test and normal karyotype results. Four markers [interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-alpha, and ischemia-modified albumin (IMA)] were studied in amniotic fluid. RESULTS: The mean age of the women in the study and control groups was 34.0+/-5.6 and 33.6+/-7.2 years, respectively. The women in the study and control groups had similar clinical and laboratory characteristics. The mean amniotic fluid IL-6 (414.84+/-83.96 vs. 343.02+/-110.59, p=0.002) and IL-8 (377.61+/-243.31 vs. 261.90+/-201.29, p=0.029), TNF-alpha (24.91+/-5.78 vs. 21.60+/-5.55, p=0.014), and IMA (1.19+/- 0.10 vs. 1.05+/-0.12, p<0.001) values were significantly increased in the study group when compared to controls. CONCLUSION: The higher amniotic fluid cytokine and ischemia-modified albumin levels in patients with false-positive first or second trimester biochemical Down syndrome screening test may result from subclinical fetal membrane inflammation and/or ischemia.

Coexistence of Mayer-Rokitansky-Kuster-Hauser syndrome and neurofibromatosis type I.

Neurofibromatosis type 1 (NF-1) is the most frequently seen form of neurofibromatosis. The characteristic features of this disorder are café au lait macules, neurofibromas, axillary and inguinal freckling, Lisch nodules, bone lesions such as sphenoid dysplasia, and optic glioma. Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rarely seen disease characterized by complete vaginal agenesis and uterine aplasia/hypoplasia. We report a case of an 18-year-old female patient who presented with complaints of brown marks, freckling, and primary amenorrhea. NF-1 and MRKH syndrome were diagnosed by physical examination and radiologic imaging. To our knowledge, this is the first report of coexistence of these rare genetic diseases in the literature.

Skin venous thromboembolism by combined oral contraceptive in a woman with acquired angioedema and Factor V Leiden mutation.

OBJECTIVE: The purpose of this study is to report a case of acquired angioedema and Factor V Leiden mutation in a woman who had started taking an oral contraceptive (OC), and to review the literature. RESULTS: A 44-year-old nonobese and nonsmoking woman was admitted to our hospital because of pain and progressive erythematous lesion on her left groin. The patient had had a 6-week history of combined OC use. There was no family history of angioedema. With a diagnosis of necrotizing fasciitis, surgical debridement of all necrotic tissue was considered with fasciocutaneous flap. Histopathological analysis showed diffusely fresh bleeding areas with diffused subcutaneous necrosis. The culture of the necrotic tissue was negative. Postoperatively, she restarted combined OC, and then the painful petechial and rapidly disseminated ecchymotic lesions were seen. Oral contraceptive was stopped immediately. A venous Doppler ultrasonography of the lower extremities showed subacute thrombosis in the left popliteal vein. Complement C3 level was normal, but amounts of C4, C1 esterase inhibitor level and activity were low. Factor V Leiden was positive for the heterozygous presence of Factor V gene. CONCLUSIONS: Women with angioedema and Factor V Leiden should be counseled against using hormonal contraceptives containing estrogen, and because they may interact in a synergistic manner in the pathogenesis of cutaneous lesions and/or venous thrombosis, appropriate individualized therapy should be defined. Further studies are needed.

The frequency of chromosomal abnormalities in patients with reproductive failure.

OBJECTIVE: To investigate the ratio of chromosomal abnormalities in recurrent fetal wastage. STUDY DESIGN: We conducted a study of the cytogenetic data of 645 couples (1290 patients) with recurrent fetal wastage examined at the Department of Medical Biology and Genetics, Trabzon, Turkey. Couples who had first trimester miscarriages/abortion, preceded or followed by a second or third trimester fetal death/fetal abnormalities were recruited from Obstetrics and Gynecology Clinics for cytogenetics analysis. RESULTS: Chromosome abnormalities were found in 25 (3.86%) patients. The chromosomal abnormalities were structural (3.71%) and numerical (0.15%). Polymorphisms of heterochromatin blocks and inv(9) were shown in 115 (17.51%) patients. CONCLUSIONS: Chromosome analyses are an important and necessary part of the etiological research in couples with recurrent fetal wastage.

Maternal outcome in HELLP syndrome requiring intensive care management in a Turkish hospital.

CONTEXT AND OBJECTIVE: Despite the development of tertiary care facilities, intensive care and advanced blood banking techniques, pregnancy-related hypertensive disorders are the main cause of maternal mortality in most countries. Our purpose was to determine maternal outcome in pregnancies complicated by HELLP syndrome (hemolysis, elevated liver enzymes and low platelet count) that required intensive care management. DESIGN AND SETTING: Retrospective study at Department of Obstetrics and Gynecology, and Department of Anesthesiology and Reanimation, Karadeniz Technical University, Trabzon, Turkey. METHODS: 37 patients with HELLP syndrome admitted to the obstetric intensive care unit were analyzed retrospectively from 1992 to 2004. RESULTS: All patients were hypertensive, with mean Glasgow coma score (GCS) of 11 +/- 3.96. Mean gestational age at delivery was 32 +/- 4.09 weeks. Delivery was vaginally in nine and by cesarean section in 27 patients. General anesthesia was used in 12 and spinal anesthesia in 25 patients. Maternal morbidity included acute renal failure (11%), disseminated intravascular coagulation (5%), acute lung edema (3%), severe ascites (11%), pleural effusion (3%), adult respiratory distress syndrome (11%), abruptio placenta (11%), cerebral edema (8%) and cerebral hemorrhage (40%). All patients required transfusions using blood products. There were 11 maternal deaths (30%). CONCLUSION: Because of high maternal mortality and morbidity found among patients with HELLP syndrome, standard antenatal follow-up protocols should be applied, so as to obtain early diagnosis and improve the speed of transfer to obstetric departments with expertise in this field.

The relationship between serum dehydroepiandrosterone sulfate concentration and bone mineral density, lipids, and hormone replacement therapy in premenopausal and postmenopausal women.

OBJECTIVE: To investigate the relationship between serum dehydroepiandrosterone sulfate (DHEAS) concentration and bone mineral density (BMD), lipids, and hormone replacement therapy (HRT) in postmenopausal women. METHODS: Two hundred twenty-seven women aged >40 years were admitted to the study and divided into three groups: 61 premenopausal normally menstruating women, 108 postmenopausal women who were not receiving HRT, and 58 postmenopausal women receiving HRT. DHEAS levels and lipid patterns were measured. BMD measurements of the lumbar spine (L1-L4) were performed by dual-energy x-ray absorptiometry (DXA). RESULTS: A positive correlation between DHEAS levels and BMD was found in all three groups. A linear regression model was used to assess the effect of age, body mass index (BMI), parity, and BMD of lumbar vertebrae (L1-L4) on changes in the serum level of DHEAS and found that aging and BMD at the spine had a significant association with serum level of DHEAS and only aging after adjustment for age, BMI, parity, and lipid patterns among the three groups. Age (RR 0.80), DHEAS (RR 0.98), and osteoporosis/osteopenia rate (RR 24.94) were also found to be independent influencing factors for HRT use. CONCLUSIONS: A positive correlation between DHEAS levels and BMD was found in all three groups. Our study confirms earlier reports that DHEAS levels decrease with age in premenopausal and, especially, postmenopausal women regardless of estrogen treatment. DHEAS levels in postmenopausal women were not associated with atherogenic lipid patterns in the present study.

Primary retroperitoneal liposarcoma.

A retroperitoneal liposarcoma that marginally involved the right kidney and ovary was presented clinically as an adnexial mass in a 61-year-old woman. At laparatomy a large retroperitoneal mass in addition to the right kidney and ovary was removed totally. A well-differentiated retroperitoneal liposarcoma was detected in histological speciment. Adjuvant irradiation was given. The 5-year survival rate of retroperitoneal liposarcoma is low. Curative resection remains the main treatment for primary and recurrent liposarcomas.

Leiomyosarcoma of the Uterus Presenting with Thrombotic Thrombocytopenic Purpura.

Thrombotic thrombocytopenic purpura (TTP) typically presents with consumptive thrombocytopenia, non-immune intravascular hemolytic anemia, renal failure, various neurologic findings and fever. It is a clinical syndrome that can be associated with drugs such as ticlopidine, quinine, mitomycin C and cyclosporine, allogeneic stem cell transplantation, pregnancy, infections, autoimmune diseases and metastatic carcinoma. Here, we describe a 48-years- old women presented with full picture of TTP and diagnosed as leiomyosarcoma with further evaluation. She was successfully treated with multiple exchange transfusions and total excision of leiomyoma thereafter. As far as we know, this is the first case of leiomyosarcoma of the uterus presented with TTP. Therefore, the women with TTP, in whom no other cause can be found, should undergo a careful gynecological examination and pelvic ultrasonography should be performed.

The Diagnostic Value of ß-Human Chorionic Gonadotropin, Progesterone, and Ischemia-Modified Albumin and Their Combined Use in the Prediction of First Trimester Abortions.

Objective. To investigate serum levels of free ß-HCG, progesterone, and ischemia-modified albumin (IMA) and their combined use in the prediction of first trimester abortions. Methods. A total of 156 pregnant women between 5 and 13 weeks of gestational age were included in this study. At admission, serum levels of free ß-HCG, progesterone, and IMA were noted and all cases were divided into two groups; Group I (n = 77) resulted in abortion including missed abortion, incomplete/complete abortion, and inevitable abortion whereas Group II (n = 79) included normal pregnancies. Results. Compared to Group II, the significantly decreased value of free ß-HCG progesterone and significantly increased value of IMA were found in Group I (P < 0.01, P < 0.01, P < 0.01, resp.). When combining all three parameters, sensitivity 75%, specificity 99%, PPV 98%, and NPV 76% were obtained. The multivariate logistic regression analysis revealed the free ß-HCG, progesterone, and IMA independent factors in the prediction of abortions. Conclusions. The combined use of free ß-HCG, progesterone, and IMA levels can be useful in the prediction of first trimester spontaneous abortions.

Multicenter analysis of gestational trophoblastic neoplasia in Turkey.

BACKGROUND: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. MATERIALS AND METHODS: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. RESULTS: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. CONCLUSIONS: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.

Thoracopagus conjoined twins: a case report.

Objective. Conjoined twin is a rarely seen congenital anomaly together with severe mortality and morbidity. The more common types of conjoined twins include the thoracopagus type, where the fusion is anterior, at the chest, and involves the heart. We are reporting one case of conjoined thoracopagus twins diagnosed by ultrasonography at 11 weeks. Case Report. In a multigravid pregnant woman who has been admitted to our clinic with a diagnosis of conjoined twins, thoracopagus, by ultrasonography at an 11-week gestation, termination of the pregnancy was performed. Conclusion. Making an early diagnosis with ultrasonographic examination gives the parents a chance to elect pregnancy termination.

Acute alterations in biochemistry, morphology and contractility of rat isolated urinary bladder via increased intra-abdominal pressure.

OBJECTIVE: To determine the acute effects of increased intra-abdominal pressure (IAP) on the biochemistry, morphology and contractility of the rat isolated urinary bladder using an experimental laparoscopy model. METHODS: We divided 24 adult female Sprague-Dawley rats into three groups. The control group (group I) was not subjected to increased IAP. In groups II and III, IAPs of 10 and 20 mm Hg, respectively, were established by carbon dioxide pneumoperitoneum for 60 min. Thirty minutes after desufflation, the rat urinary bladder dome was removed for in vitro pharmacological investigation, measurement of malondialdehyde (MDA) levels and histopathological examination. Statistical comparisons between groups were performed. RESULTS: Tissue MDA levels in groups II and III were significantly higher than in the control group. In group II, only the lamina propria was significantly damaged. However, the epithelium, lamina propria, and serosa were significantly damaged in group III. Acetylcholine potentiated contractions in both IAP groups. Increased responses to electrical field stimulation in the IAP groups were significant only in group II. CONCLUSIONS: In this experimental model, 10 and 20 mm Hg of IAP induced by pneumoperitoneum increased MDA levels and caused important changes in the morphology and contractile response of the urinary bladder.

The acute alterations in biochemistry, morphology, and contractility of rat-isolated terminal ileum via increased intra-abdominal pressure.

AIM AND SCOPE: To determine the acute effects of increased intra-abdominal pressure (IAP) on the biochemistry, morphology, and contractility of the isolated terminal ileum of rats. BACKGROUND: Laparoscopic procedures are used clinically in diagnostic and treatment modalities and experimentally as a model of ischemia-reperfusion injury induced by the elevation of IAP. Although some clinical and in vivo experimental studies investigate the results of ischemia-reperfusion injury whether induced by elevated IAP or clamping, there is no in vitro study that has investigated the acute effects of high IAP mimicked by a laparoscopic intervention in any of the intra-abdominal organs (like terminal ileum) on the basis of contractility which represents the motility. METHODS: Twenty-four adult with either sex Sprague-Dawley rats were divided into three groups. The control group (Group I) was not subjected to any IAP. In Groups II and III, an IAP of 10 and 20 mmHg, respectively, was established by carbon dioxide pneumoperitoneum for a period of 60 min. Thirty minutes after the desufflation, the terminal ileum was removed for in vitro pharmacological investigation, measurement of malondialdehyde (MDA) values, and histopathological examination. Statistical comparisons among groups were done using the Kruskal-Wallis variance analysis, with post hoc comparison performed with the Mann-Whitney U-test. RESULTS: Tissue MDA value and the damage scores of mucosa and submucosa were significantly increased in both IAP groups. The smooth muscle layer was significantly damaged only in Group III. The contractions obtained by electrical field stimulation (EFS) were inhibited in both IAP groups, and the contractions to acetylcholine were inhibited in Group III when compared to the control group. CONCLUSIONS: In conclusion, we can say that pneumoperitoneum induced IAP may inhibit contractile responses, cause structural alterations which may be related to ischemia-reperfusion injury in rat terminal ileum.

The association of birthweight with maternal and cord serum and amniotic fluid growth hormone and insulin levels, and with neonatal and maternal factors in pregnant women who delivered at term.

AIM: To investigate the influence of maternal and cord serum and amniotic fluid growth hormone (GH) and insulin and other neonatal and maternal factors on birthweight. METHODS: A total of 160 pregnant women at 38-42 weeks' gestation were studied. All infants were categorized as small for gestational age (SGA) (n = 50), large for gestational age (LGA) (n = 50) or average for gestational age (AGA) (n = 60). GH and insulin levels were measured in maternal and cord serum and amniotic fluid at birth. RESULTS: GH levels in maternal and cord serum and amniotic fluid showed no differences among the three weight groups (P > 0.05). The cord insulin level was significantly lower in SGA (P < 0.01). The insulin level in venous cord blood correlated with birth and placental weights and neonatal height, whereas maternal serum and amniotic fluid insulin levels, and maternal and cord serum and amniotic fluid GH levels did not show any correlation with birthweight. The cord GH level at birth was correlated with GH levels after 4 postnatal weeks in the SGA group (P < 0.01). In addition, birthweight showed a correlation with prepartum maternal weight, maternal weight gain, maternal height, neonatal length and placental weight in all three weight groups. CONCLUSIONS: Cord GH, maternal serum and amniotic fluid GH and insulin levels did not correlate with birthweight in all three weight groups. The lack of correlation for GH levels in maternal and cord serum and amniotic fluid suggests that these compartments may be non-communicating separate units.

Chorioamnionitis risk and neonatal outcome in preterm premature rupture of membranes.

OBJECTIVE: The objective of this study was to compare the neonatal outcome in patients with preterm premature rupture of membranes with and without clinical chorioamnionitis. STUDY DESIGN: This is a retrospective study that included 254 pregnant women with preterm rupture of membranes. The study group was divided according to the presence or absence of clinical chorioamnionitis defined as the presence of two or more of the following criteria: maternal temperature >38 degrees C on two or more occasions > or =1 h apart, maternal tachycardia (> or =120 beats/min), uterine tenderness, foul smelling amniotic fluid, maternal leukocytosis > or =20,000 mm(-3) with bands and positive C reactive protein. Also the study population was divided according to the use of tocolysis. Exclusion criteria included multiple pregnancy, fetal congenital anomalies, diabetes mellitus and severe preeclampsia. Amniotic fluid was collected from the cervix or from the transabdominal amniocentesis. Antibiotics and tocolysis were used according to the hospital protocols. Parametric and nonparametric statistics were used for comparisons. RESULTS: There were no significant differences in birth weight, Apgar scores at 1 and 5 min, rates of respiratory distress syndrome, intraventricular hemorrhage and necrotizing enterocolitis between patients with and without clinical chorioamnionitis or between women who received tocolysis and the ones that did not receive tocolysis. In cases of clinical chorioamnionitis and when tocolysis was used the neonates stayed longer in the neonatal intensive care unit (NICU). CONCLUSION: Patients with preterm premature rupture of membranes and clinical chorioamnionitis have similar neonatal outcomes than the ones without clinical chorioamnionitis.

Coagulation inhibitors in preeclamptic pregnant women.

OBJECTIVE: Our objective was to detect clinical evaluation of coagulation inhibitors in preeclamptic and normotensive pregnant women and to determine their important role in pathogenesis of preeclampsia. METHODS: A total of 20 mild, 20 severe preeclamptic and 45 normotensive pregnant women were included in this study. The plasma value of antithrombin III (AT-III) activity, proteins C and S activity, PT, PTT, fibrinogen and platelet counts were determined. RESULTS: The values AT-III were lower in women with severe preeclampsia than in controls (p<0.05). In all groups, there was no significantly difference in the concentration of protein C activity, protein S and fibrinogen (p>0.05). The plasma thrombocyte counts were significantly lower in severe preeclamptic women than in normotensive women (p<0.05). There was no significant difference in the prothrombin time value in all groups, but a significantly difference with regard to partial thromboplastin time between severe preeclamptic and the control group (p<0.0001). It was longer than the control. CONCLUSION: The markers of hemostasis activation such as protein S, protein C activity together with fibrinogen levels are not useful tools but the reduction of AT-III and platelet counts would seem useful in different pathological situations in pregnancy to predict and monitor the severity of the condition.

Effect of different preparations of hormone therapy on lipid and glucose metabolism, coagulation factors, and bone mineral density in overweight and obese postmenopausal women.

OBJECTIVE: To determine the effects of different preparations of hormone therapy (HT) on lipid and glucose metabolism, coagulation factors, and bone mineral density (BMD) in overweight and obese postmenopausal women. DESIGN: A randomized, nonblinded, controlled study. SETTING: Karadeniz Technical University, Department of Obstetrics and Gynecology. PATIENT(S): A total of 352 overweight and obese (body mass index >25 kg/m2) postmenopausal women. INTERVENTION(S): Ninety women received 2.5 mg of tibolone; 84 received 2 mg of E2 plus 1 mg of norethisterone acetate (E2/NETA); 90 received 0.625 mg of conjugated equine estrogen plus 2.5 mg of medroxyprogesterone acetate (CEE/MPA); and 88 did not receive any menopausal therapy (control). MAIN OUTCOME MEASURE(S): At baseline and after 6 months of treatment, we measured total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), insulin, glucose, factor VII, factor VIII, von Willebrand factor, antithrombin III, protein S, protein C, fibrinogen, and BMD at the lumbar spine L1-L4. RESULT(S): There were no statistically significant differences among the groups for any variables at baseline. After 6 months of treatment, the three regimens decreased total cholesterol, triglyceride, LDL, and fibrinogen; E2/NETA and CEE/MPA increased HDL, and tibolone decreased HDL; higher insulin concentrations were found in the control and tibolone groups. Body mass index, HDL, fibrinogen levels, and L1-L4 BMD were independent factors in the prediction of HT use. CONCLUSION(S): Body mass index, HDL, fibrinogen levels and L1-L4 BMD were independent factors in the prediction of HT use. Treatment with tibolone, E2/NETA, and CEE/MPA resulted in minimal improvement in lumbar spine BMD but had a beneficial effect on the procoagulation system, with minimal changes in glucose metabolism after 6 months of therapy.

The effects of short-term raloxifene therapy on fibrinolysis markers: TAFI, tPA, and PAI-1.

BACKGROUND: Markers of fibrinolysis, thrombin-activatable fibrinolysis inhibitor (TAFI), tissue-type plasminogen activator (tPA), and plasminogen activator inhibitor-1 (PAI-1) levels were studied for the evaluation of short-term effects of raloxifene administration in postmenopausal women. METHODS: Thirty-nine postmenopausal women with osteopenia or osteoporosis were included in this prospective, controlled clinical study. Twenty-five women were given raloxifene hydrochloride (60 mg/day) plus calcium (500 mg/day). Age-matched controls (n = 14) were given only calcium. Plasma TAFI, tPA, and PAI-1 antigen levels were measured at baseline and after 3 months of treatment by commercially available ELISA kits. Variations of individuals were assessed by Wilcoxon's test. Relationship between those markers and demographic characteristics were investigated. RESULTS: Three months of raloxifene treatment was associated with a significant decrease in the plasma TAFI antigen concentrations (16% change, P < 0.01), and a significant increase in tPA antigen concentrations (25% change, P < 0.05). A significant correlation was found between baseline TAFI antigen concentrations and the duration of amenorrhea (P < 0.05; r = 0.33). CONCLUSION: We suggest that the increased risk of venous thromboembolism due to raloxifene treatment may be related to increased tPA levels, but not TAFI levels.
