Growth factors and metabolic markers in cord blood: relationship to birth weight and length.

Low birth weight and length for gestational age are associated with a high risk of short stature and metabolic syndrome in adulthood. The mechanisms that link prenatal growth to adult stature and metabolic syndrome have not yet been entirely clarified. The aim of our study was to evaluate the relationship between standardized anthropometric measures at birth and insulin-like growth factor (IGF)-I, IGF-II, insulin, adiponectin, and non-esterified fatty acid (NEFA) cord blood levels in the general population. One hundred fifty-eight random newborn subjects (77F, 81M) from Genoa, Italy, were analyzed. Anthropometric parameters were measured and standardized according to standard Italian tables. Insulin values were treated as categorical, since in several cases the results fell below detection cut-off. Mean birth weight was 3,214.23∓488.99 gr and mean length was 49.82∓2.17 cm. Females had higher mean IGF-I (p=0.04), and were more likely to have insulin values either <2 μU/ml or >4.5μU/ml (p= 0.04) compared to males. Weight and length SD scores (SDS) were higher in subjects with elevated insulin levels (p=0.002). A moderate correlation was found between weight and IGF-II (r=0.354). Multivariable analysis demonstrated that standardized birth weight was associated with IGFII and insulin values. Our data highlight the importance of IGF-II in fetal growth and suggest that gender differences should be taken into consideration when evaluating prenatal growth.

Ten years survival of FIGO stage IIIC epithelial ovarian cancer cases due to lymph node metastases only.

PURPOSE OF INVESTIGATION: In this paper the authors have analyzed the long-term survival of women with Stage III ovarian cancer due to lymph node metastasis. MATERIALS AND METHODS: This retrospective study included 27 patients with FIGO Stage IIIC epithelial ovarian carcinoma due to lymph node metastases observed consecutively at the Mangiagalli Clinic of Milan from 1982 to 2008. RESULTS: Two cases had Fallopian tube carcinoma. A total of ten recurrences were observed. Median time to recurrence was 158 months. The five-year disease-free survival (DFS) was 57.7%. The ten-year corresponding value was 53.2%. Median survival time was 158 months, with median follow-up time of 169 months. The five-year (overall survival) OS rate was 77.1%; the ten-year rate was 55.4%. CONCLUSION: Women with ovarian cancer Stage IIIC due to nodal involvement have a five-year OS of about 80% and a ten-year OS of about 50%.

Mediterranean diet and the risk of poor semen quality: cross-sectional analysis of men referring to an Italian Fertility Clinic.

BACKGROUND: Several diet patterns have been suggested as involved in processes of spermatogenesis and thus in male subfertility. To study the relation between Mediterranean diet and abnormal sperm parameters in men of subfertile couples, we performed a cross-sectional analysis of baseline data from a prospective cohort study. METHODS: Patients were enrolled in an Italian Fertility Clinic. Couples undergoing assisted reproduction techniques (ART) were interviewed to obtain information on personal and health history, lifestyle habits, and diet, on the day of oocyte retrieval. On the same day, a semen sample was also collected and analyzed to proceed with ART. Adherence to Mediterranean diet was evaluated using a Mediterranean Diet Score (MDS). Odds ratios (OR) and 95% confidence intervals (CI) were calculated for semen volume <1.5 mL, sperm concentration <15 mil/mL, and total count <39 mil. RESULTS: Three hundred nine men, age range 27-60, were enrolled: 19.3% had semen volume < 1.5 mL, 30.5% sperm concentration <15 mil/mL, and 32.1% total count <39 mil. MDS was low (0-3) in 86 men (27.8%), intermediate (4-5) in 131 (42.4%), and high (6-9) in 92 (29.8%). Semen volume was not associated with MDS. Compared to the highest MDS category (6-9), the ORs for low sperm concentration were 1.34 (95% CI 0.69-2.50) for MDS 4-5 and 2.42 (95% CI 1.21-4.83) for MDS 0-3, with significant trend (p = 0.011). The corresponding estimates for total count were 1.26 (95% CI 0.66-2.42) and 2.08 (95% CI 1.05-4.12), with significant trend (p = 0.034). These findings were consistent in strata of history of reproductive organ diseases. CONCLUSIONS: Mediterranean Diet Score was positively associated with normal sperm concentration and total count, but not with semen volume.

Alcohol intake and semen variables: cross-sectional analysis of a prospective cohort study of men referring to an Italian Fertility Clinic.

BACKGROUND: The association between alcohol intake and male reproductive function is still controversial. In the frame of a prospective cohort study, designed to investigate the relation between life style and fertility, we performed a cross-sectional analysis of semen quality. METHODS: Men of subfertile couples, referring to an Italian Infertility Unit and eligible for assisted reproductive techniques (ARTs), were asked about their lifestyle: BMI, smoking, caffeine intake, occupational and leisure physical activity (PA) and alcohol intake in the last year before ART procedure. Semen volume, sperm concentration, total sperm count and sperm motility were determined. Age, risk factors for impaired male fertility, caffeine, smoking, leisure PA, days of abstinence and daily calories intake were accounted for in the analyses. RESULTS: Between September 2014 and December 2016, we enrolled 323 male patients, mean age 39.3 years. Thirty-one (9.6%) were abstainers, 97 (30.0%) drank <1-3, 98 (30.3%) 4-7 and 97 (30.0%) ≥8 alcohol units per week. As compared to men drinking <1-3 units per week, median semen volume was higher in the 4-7 units/week group (3.0 mL, interquartile range, IQR, 2.0-4.0 vs. 2.4 mL, IQR 1.7-3.5), as well as total sperm count (87.9 mil/mL, IQR 20.2-182.1 vs. 51.5 mil/mL, IQR 15.2-114.7). Association with sperm concentration was also significant, with a U-shaped trend in groups of alcohol intake. After adjusting for potential confounders, these relations were confirmed. Similar patterns were observed in subgroups of leisure PA and risk factors for impaired male fertility, although these estimates often lacked statistical significance, presumably because of low sample size. CONCLUSIONS: Moderate alcohol intake appears positively associated to semen quality in male partners of infertile couples undergoing ARTs.

Epidemiology of endometriosis and its comorbidities.

Genetic profile, inflammation, hormonal activity, menstrual cyclicity, organochlorine burden, prostaglandin metabolism and immunological factors have been suggested to play a role in the establishment and development of endometriosis. From the epidemiological perspective, several risk factors have been studied to suggest or support the different aetiological hypotheses. Social class and family history apart, the factors most consistently associated with endometriosis are early age at menarche and long and heavy menstrual cycles. These menstrual characteristics (together with nulliparity) reflect increased exposure to menstruation. The other main risk factors are pigmentary traits and sun habits, alcohol intake, use of oral contraceptives, and environmental factors such as exposure to polychlorinated biphenyls and dioxin. All of these factors support a potential role of hormonal mileau and inflammation in the pathogenesis of endometriosis. There is a clear association between endometriosis and gastrointestinal and immunological diseases, ovarian cancer and other gynaecological cancers, and thyroid cancer.

[Hemodynamic changes in liver and multi-organ transplantation]. / Modificazioni emodinamiche nel trapianto epatico e nel trapianto multiviscerale.

Multivisceral transplantation is a surgical technique developed as treatment for abdominal metastatic and/or multifocal malignancies. At present its clinical employment is reduced by our fragmentary knowledge of the intraoperative and postoperative outcome. The aim of this study is to compare intraoperative hemodynamic and respiratory changes during multivisceral transplantation (MTV, n = 12) and liver transplantation (OLTX, n = 14). The observations have been carried out a 4 phases: basal (I), visceral (II), reperfusion (III), final (IV). Phase I does not show differences between MTV and OLTX. In phase II MTV presents a lower temperature (T) and pulmonary arterial pressure (PAP) (p > 0.05). Phase III is marked by increasing T differences (p < 0.05), lower cardiac frequency (CF), pH and base excess (BE) (p < 0.05). PAP and cardiac output (CO) show a higher value in MTV (p < 0.05). Phase IV reports the vital signs close to normality in both groups, except pH in MTV (p > 0.05).

[Flexibility of the surgical model of intestinal transplantation in swine]. / Flessibilità del modello chirurgico di trapianto intestinale sperimentale nel suino.

AIM: To verify the feasibility to introduce variations in the technique of intestinal transplantation, we developed three different intestinal transplant models in pigs. EXPERIMENTAL DESIGN: Feasibility and comparative study. ENVIRONMENT: Pre-clinical organ transplant surgery. MATERIALS AND METHODS: Sixty outbread piglets (mean weight 27.1 +/- 4.4 kg) received a total orthotopic intestinal allograft from equivalent donors perfused through the aorta with UW solution at 4 degrees C. Intraluminal flushing of the graft was always avoided. The animals were divided in 3 groups according to the transplantation procedure adopted. Group 1 (n = 9): excision of small and large bowel and replacement with small bowel only; group 2 (n = 39): excision of small bowel and its replacement; group 3 (n = 12): excision of small and large bowel and their "en-bloc" replacement. The superior mesenteric artery and vein were anastomosed end-to-end in all groups. RESULTS: The lowest perioperative mortality occurred in group 2 (28%), followed by group 3 (58%) and group 1 (78%). However, in group 1 the incidence of perioperative deaths was influenced by our learning curve in surgical and anesthesiologic management. No significant differences were noted in terms of cold and warm ischaemia time of the grafts, length of operative time, histopathologic analysis of preservation injury. The addition of the colon in the transplanted graft resulted in a more critical hemodynamic profile at reperfusion. CONCLUSION: Three different experimental models of intestinal transplantation are feasible in pigs. The choice can be made based on the type of study needed.

[The hemodynamic effects of the in-vivo administration of insulin-like growth-factor I]. / Effetti emodinamici della somministrazione in vivo dell'Insulin-like Growth Factor-I.

BACKGROUND: Recent studies have demonstrated that IGF-I has several biological activities that correlate with the GH axis, by acting as a cell protecting factor and a promoting compound in different tissues and organs. Our latest findings have demonstrated a potential application of IGF-I in the treatment of postischemic renal injury, which frequently appears after a kidney transplant. The beneficial effect of the renal postoperative recovery probably correlates with the regulation of the vascular tone, in which IGF-I plays a role with other cytokines. However, this rises the question whether IGF-I has any effect on the general hemodynamic status. This study was designed to underline the intraoperative hemodynamic effect of exogenous IGF-I in an experimental setting of renal transplantation in swine. METHODS: Twelve female swine underwent a left renal autotransplantation. At the reperfusion the animals were separated in two groups. Group one served as control. Group two received 400 micrograms of IGF-I (added to the flushing solution). The animals were kept under complete hemodynamic monitoring over the operation. RESULTS: Among the different parameters studied (mean arterial pressure, mean pulmonary arterial pressure, pulmonary wedge pressure, central venous pressure, cardiac output, oxygen extraction ratio, systemic vascular resistance, oxygen delivery and oxygen consumption), any statistically significant difference between group one and two were observed. CONCLUSIONS: While the clinical administration of IGF-I requires further studies, the in vivo administration of this peptide is apparently well tolerated, and does not cause any hemodynamic instability to the operation.

[Atracurium besylate versus succinylcholine during laparoscopy]. / Besilato di atracurium versus succinilcolina in corso di laparoscopia.

The authors report their experience with 112 female patients undergoing laparoscopy: they have been divided into two groups according to the drug used for muscle relaxation (atracurium versus succinylcholine). During the procedure the following parameters were recorded: intraabdominal pressure, arterial pressure, heart rate, arterial blood oxygen saturation, end tidal CO2 and the occurrence of adverse effects. According to the collected data they assume that atracurium can be considered the ideal muscle relaxant for this surgical procedure.

[Intravenous anesthesia during oocyte harvesting for in vitro fertilization. Description of a method]. / Anestesia endovenosa in corso di prelievo di ovocita per fecondazione in vitro. Descrizione di una metodica.

The Authors describe their anaesthetic technique with a continuous i.v. infusion of propofol in female patients undergoing oocyte retrieval during in vitro fertilization. With this technique a great stability of the haemodynamic and respiratory parameters was recorded, adverse effects were never observed and every patient quickly regained a normal psychomotor performance. This operation can be, therefore, carried out in ambulatory regimen with complete safety and good acceptability from the patients.

[Electric cardioversion in pregnant patients with obstructive hypertrophic cardiomyopathy. A clinical case]. / Cardioversione elettrica in paziente gravida affetta da miocardiopatia ipertrofica ostruttiva. Caso clinico.

A case of atrial fibrillation during pregnancy in a woman at 30 weeks of gestation is described. She was affected by obstructive hypertrophic myocardiopathy, a rare disease usually non interfering with the normal course of pregnancy. The mortality rate is of 2-4% per year. The most frequent cause is "cardiac sudden death". High frequency atrial fibrillation can lead to right and left cardiac failure. The treatment of atrial fibrillation is to be chosen between a pharmacological or electrical therapy. However, during pregnancy, pharmacological cardioversion, although not excluded, could cause damaging side effects to the fetus. Conversely, according to literature, electrical cardioversion is effective on the mother and safer for the fetus. At admission the patient showed dyspnea, palpitations, tachycardia and hypotensions; ECG showed an atrial fibrillation at high frequency that required an immediate therapeutic decision. In the case we studied, we reported the recovery of cardiac rhythm with a single synchronized electric shock. Non alteration of fetal cardiac rhythm or uterine contractility was observed. Pregnancy went on without accidents until the 36th week, when a cesarean section was performed under general anaesthesia. We described our experience reviewing previous literature on the account of the rareness of the disease, its association to a pregnancy and the serious alterations of cardiac rhythm at the admission, which led us to take an immediate decision, safeguarding both the mother and the fetus.
