RESUMEN
Coronary artery calcifications(CACs), are related to the increased cardiovascular mortality during kidney transplantation(KTx). Using coronary-CT performed at 1 month(T0) and 5 years(T5) after KTx we evaluated: (1) the prevalence of CACs; (2) the clinical and biochemical factors related to CACs; 3) the factors implicated with CACs progression. We evaluated 67-pts selected from the 103-pts transplanted in our unit between 2007 and 2008. Clinical and biochemical parameters were recorded at the time of pre-KTx evaluation and for five years after KTx. Coronary-CT for the Agatson score (AS) evaluation was performed at T0 and at T5, and CACs progression was determined. At baseline AS was 45 [0-233]. At T5 AS was 119 [1-413]. At T0, 69% of patients had CACs. Age and dialytic vintage were the main independent variables related to CACs. At T5, CACs were present in 76% of patients. Age was the only independent factor in determining CACs. A progression of CACs was observed in 74% of patients. They were older, had higher CACs-T0 and higher SBP throughout the 5-years. The presence of CACs at T0 and age were the only independent factors in determining the CACs-progression. CACs-T0 had the best discriminative power for CACs progression. CACs prevalence is quite high in KTx patients; Age is strictly related to CACs; Age and the presence of CACs at baseline were the two major factors associated with the progression of CACs during the five years of follow up. CACs-T0 had the best discriminative power for progression of CACs.

Single-antigen bead (SAB) platform permits the identification of antibodies not detectable by complement-dependent lymphocytotoxicity test, but their clinical significance is not completely understood. The aim of this study was to evaluate whether the presence of pretransplant SAB-detected antibodies is associated with the development of allograft failure. This is a single-center cohort study with 10-year follow-up in which 573 kidney recipients with negative pretransplant complement-dependent lymphocytotoxicity crossmatch who received transplants at the Kidney Transplant Center of Policlinico, Milan, from deceased donors between 1996 and 2005 were evaluated. Pretransplant plasma samples were retrospectively analyzed by SAB assay. Survival analyses were performed to assess the risk of allograft failures by SAB-detected antibodies. Pretransplant antibodies were found in 160 (28.0%) recipients, of whom 42 subsequently developed an allograft failure for a survival rate of 70.9% (95% confidence interval [CI), 63.5-78.4). Among those without antibodies, 58 (14.0%) returned to dialysis with a survival rate of 84.7% (95% CI, 81.0-88.4). In Cox regression analyses, patients with SAB-positivity had 2-fold higher risk of allograft failure than those who were SAB-negative (hazard ratio, 2.07; 95% CI, 1.39-2.79). Results did not change after adjustment for putative confounders. In conclusion, in this single-center cohort, 10-year allograft survival rate was significantly influenced by the presence of SAB-detected antibodies.

Renal biopsy (RBx) informs about kidney transplantation (KTx) prognosis. In our observational study the prevalence of histological anomalies and the prognostic role of CD45, vimentin (VIM) and periostin (POSTN) in KTx-RBx have been evaluated. One hundred forty-six KTx-RBx (2009-2012) were analysed for general histology and in immunohistochemistry for CD45, VIM and POSTN. Clinical data of the 146-KTx patients were collected at the RBx time (T0), 6 and 12 months before and after RBx. Follow-up time was 21 ± 14 months. Glomerulosclerosis was 20% glomeruli/biopsy. Tubular atrophy (TA), Interstitial infiltrate (I-Inf) and interstitial fibrosis (IF) were slight in 21-18% and 25%, moderate in 22-30% and 26% and severe in 30-18% and 28% of patients. Fifty-eight percent of patients had lesions compatible with IF-TA. CD45, VIM and POSTN correlated to each-other and to TA, I-Inf and IF. VIM and POSTN correlated to GS. CD45 and VIM correlated directly to renal function (RF) and 25(OH)VitD, while POSTN inversely to 25(OH)VitD. Thirty patients restarted dialysis (HD+). HD+ had lower T0-eGFR, and higher CD45, VIM and POSTN than HD-. POSTN resulted the strongest in discriminate for HD+ . CD45, VIM and POSTN correlate to each-other and predict graft outcome. POSTN was the strongest in discriminate for HD+. 25(OH)VitD might influence inflammation and fibrosis in KTx.

OBJECTIVES: We aimed to determine the feasibility of conducting a randomised controlled trial (RCT) on the use of aromatherapy during labour as a care option that could improve maternal and neonatal outcomes. DESIGN: RCT comparing aromatherapy with standard care during labour. SETTING: District general maternity unit in Italy. SAMPLE: Two hundred and fifty-one women randomised to aromatherapy and 262 controls. METHODS: Participants randomly assigned to administration of selected essential oils during labour by midwives specifically trained in their use and modes of application. MAIN OUTCOME MEASURES: Intrapartum outcomes were the following: operative delivery, spontaneous delivery, first- and second-stage augmentation, pharmacological pain relief, artificial rupture of membranes, vaginal examinations, episiotomy, labour length, neonatal wellbeing (Apgar scores) and transfer to neonatal intensive care unit (NICU). RESULTS: There were no significant differences for the following outcomes: caesarean section (relative risk [RR] 0.99, 95% CI: 0.70-1.41), ventouse (RR 1.5, 95% CI: 0.31-7.62), Kristeller manoeuvre (RR 0.97, 95% CI: 0.64-1.48), spontaneous vaginal delivery (RR 0.99, 95% CI: 0.75-1.3), first-stage augmentation (RR 1.01, 95% CI: 0.83-1.4) and second-stage augmentation (RR 1.18, 95% CI: 0.82-1.7). Significantly more babies born to control participants were transferred to NICU, 0 versus 6 (2%), P = 0.017. Pain perception was reduced in aromatherapy group for nulliparae. The study, however, was underpowered. CONCLUSION: This study demonstrated that it is possible to undertake an RCT using aromatherapy as an intervention to examine a range of intrapartum outcomes, and it provides useful information for future sample size calculations.

INTRODUCTION: AHSG, a serum glycoprotein with recognized anti-calcification activity, has also been suggested to modulate both bone formation and resorption. Though the bulk of AHSG is mostly synthesized in the liver, it has been claimed that also bone cells might produce it. However, the extent of the bone AHSG production and the potential controlling factors remain to be definitively proven. A relevant number of studies support the notion that FGF23, a bone-derived hormone, not only regulates the most important mineral metabolism (MM) related factors (phosphate, parathyroid hormone, vitamin D, etc.), but might be also involved in cardiovascular (CV) outcome, both in chronic kidney disease (CKD) patients and in the general population. Furthermore, in addition to some direct autocrine and paracrine effects in bone, FGF23 has been suggested to interact with AHSG. In this study we investigated if AHSG is really produced by bone cells, and if its bone production is related and/or controlled by FGF23, using cultured bone cells, according to a new method recently published by our group. RESULTS: Our data show that AHSG is consistently produced in osteocytes and to a far lesser extent in osteoblasts. Both FGF23 addition to the culture medium and its over-expression in osteocytes were associated with a consistent increase of both AHSG mRNA and protein, while FGF23 silencing was followed by opposite effects. Though most of these results were largely affected by the blockage of FGF23 receptors, the role of these receptors in the different experimental sets is still not completely clarified. In addition, we found that FGF23 and AHSG proteins co-localized both in cytoplasm and nucleus, which suggests a possible reciprocal interactivity. CONCLUSIONS: Our data not only confirm that AHSG is produced in bone, mainly in osteocytes, but show for the first time that its production is modulated by FGF23. Since both proteins play important roles in the bone and cardiovascular pathology, these results add new pieces to the puzzling relationship between bone and vascular pathology, in particular in CKD patients, prompting future investigations in this field.

One hundred seventy-two term pregnant women with medical or obstetric conditions requiring induction of labor were treated with intracervical administration of 0.5 mg prostaglandin E2 in tylose gel. Multiple administrations were necessary in 42 cases (24.4%), two administrations in 31 cases (18.0%) and three administrations in 11 cases (6.4%). Intracervical administration of PGE2 tylose gel (0.5 mg dose) is useful to prime the cervix, induce labor, and significantly modify Bishop score.

We report how we changed the model of the organization and the assistance in our Department of healthy newborns (2200-2400/years). After we have realized that mothers were not satisfied of the rules of the hospital and personnel was not satisfied of the job, we decided to begin a process of analysis and review of the procedures on full term newborn. During this process we found out that the most important thing was to have clear in mind the problems and the needs of the mother and the baby, and not those of nurses and doctors. A similar process took place in the Department of Obstetrics. In this way we, Obstetrics and Neonatologist together, began to offer a more human approach to birth, and rooming-in began. We stopped to attend every normal delivery, to separate immediately mother and baby, to feed the baby at fixed time, to give him supplementations. We tried to have with the mother a better relationship, visiting the baby in presence of the mother an receiving grom Obstetrics as soon as possible every information about pregnancy. We realized that this was possible only if the Neonatologist and the Obstetric were of the same opinion about a more human approach to birth. We stress this point, well aware that it's impossible to reach this goal unless everybody in any way involved in birth work in great harmony with all the others. A further result of this "new" way of working has been the program of early discharge: if desired, and whenever possible, the mother and the baby go home 48-72 hours after delivery. We report here preliminary data.

BACKGROUND: External cephalic version has been advocated as a safe alternative to vaginal breech delivery or cesarean birth. The purpose of this study was to determine the efficacy of routine use of external cephalic version at 36 weeks or more of gestation in three different levels of hospitals. METHODS: External cephalic version was performed on 923 women with a single breech fetus at three hospitals in Italy. The procedure was attempted with a tocolytic agent for uterine relaxation and with no maternal analgesia. The version technique adopted was the "forward roll." RESULTS: Version was successfully performed on 579 fetuses (62.7%); each hospital had a similar success rate, and 56.9 percent of the women delivered vaginally. The procedure was more successful in multiparas and in women with an incomplete type of breech, polyhydramnios, and posterior localization of the placenta. Vaginal bleeding was experienced by 14 women; eight cesarean sections were performed for suspected abruptio placentae, confirmed in four cases. Two cephalic-turned fetuses experienced an episode of persistent bradycardia and were turned again to breech; in five cases a nonstress test recorded after the version showed repeated variable decelerations and in one case a cesarean section was performed. Neonatal outcomes were good in 922 infants. A fracture of the femur attributable to the version was observed in one newborn. CONCLUSIONS: External cephalic version is effective in reducing the number of cesarean deliveries in term breech infants in different obstetric settings, with no major neonatal adverse outcomes.

BACKGROUND: The cesarean delivery rate in Italy rose dramatically from the mid-1970s to 1996, accounting for 22.4 percent of all deliveries in the last national survey. The aim of this study was to analyze the results of the clinical practice of a new staff in the Department of Obstetrics and Gynecology of a university hospital, with particular focus on the application of common protocols. The rates of cesarean sections and perinatal mortality were chosen as parameters for good clinical practice and were compared with national data. METHODS: A new staff assumed the obstetric management at the hospital in 1982. Standardized protocols were implemented for all major indications for cesarean delivery (repeat cesarean section, dystocia, breech presentation, fetal distress). RESULTS: The rate of cesarean deliveries decreased from 26.4 to 12 percent and remained stable during the past decade. Other operative modalities were used for approximately 1.5 percent of deliveries. The perinatal mortality decreased to 0.5 percent in 1994. To confirm whether or not staff followed common protocols, a review of three years (1994-1996) showed a fairly stable frequency of cesarean sections on different days and nights during the week, confirming the homogeneity of obstetric management. CONCLUSIONS: Our data showed that, irrespective of the local situation and of the risks of litigation, a significant reduction of cesarean sections can be achieved in a tertiary care center without detrimental effects on newborns, especially in a teaching hospital where residents are trained. Despite national trends suggesting the contrary, some women may choose to deliver in an obstetrics department with better care and fewer operative procedures than in hospitals with higher cesarean delivery rates.
