Ficolin-2 is regarded as an important innate immunity factor endowed with both lectin (carbohydrate recognition) qualities and ability to induce complement activation. The aim of this study was to investigate the association of the FCN2 3’-untranslated region (3’UTR) polymorphisms with ficolin-2 expression and perinatal complications in preterm neonates. The sequencing analysis allowed us to identify six 3’UTR polymorphisms with minor allele frequency (MAF) >1%: rs4521835, rs73664188, rs11103564, rs11103565, rs6537958 and rs6537959. Except for rs4521835, all adhered to Hardy-Weinberg expectations. Moreover, rs6537958 and rs6537959 were shown to be in perfect linkage disequilibrium (LD) with nine other genetic polymorphisms: rs7040372, rs7046516, rs747422, rs7847431, rs6537957, rs6537960, rs6537962, rs11462298 and rs7860507 together stretched on a distance of 1242 bp and very high LD with rs11103565. The 3’UTR region was shown to bind nuclear extract proteins. The polymorphisms at rs4521835 and rs73664188 were found to influence serum ficolin-2 concentration significantly. All polymorphisms identified create (together with exon 8 polymorphism, rs7851696) two haplotype blocks. Among 49 diplotypes (D1-D49) created from rs7851696 (G>T), rs4521835 (T>G), rs73664188 (T>C), rs11103564 (T>C), rs11103565 (G>A) and rs6537959 (T>A), twenty two occurred with frequency >1%. Two diplotypes: D13 (GTTTGT/GGTCGT) and D10 (GTTTGT/GGTCGA), were significantly more frequent among preterm neonates with early onset of infection and pneumonia, compared with newborns with no infectious complications (OR 2.69 and 2.81, respectively; both p<0.05). The minor (C) allele at rs73664188 was associated with an increased risk of very low (≤1500 g) birthweight (OR=1.95, p=0.042) but was associated with the opposite effect at rs11103564 (OR=0.11, p=0.005).

BackgroundRecent research has reported increased risk of aggressive incidents by individuals with psychotic illness.AimsTo examine acts of aggression in first-episode psychosis.MethodSubjects with a first-episode psychosis were ascertained from a defined catchment area (Nottingham, UK) and reassessed at 3 years (n=166) using clinical interview, informants, health care and forensic records.ResultsOf the subjects, 9.6% demonstrated at least one act of serious aggression (defined as weapon use, sexual assault or victim injury) during at least one psychotic episode and 23.5% demonstrated lesser acts of aggression (defined as all other acts of aggression). For all aggressive subjects (33.1%), unemployment (OR=3.6, 95%CI 1.6–8.0), comorbid substance misuse (OR=3.1, CI 1.1–8.8) and symptoms of overactivity at service contact (OR=6.9, CI 2.7–17.8) had independent effects on risk of aggression.ConclusionsWe confirmed some previously reported demographic and clinical associations with aggression in first-episode psychosis but no relationship with specific psychotic symptoms or diagnostic groups was observed.

ObjectivesAntenatal corticosteroids (ACS) decrease neonatal mortality and morbidity among preterm neonates, yet there has been concern regarding their long-term safety. We hypothesised that potential long-term adverse effects of ACS may be observed among infants born during the late preterm period (LPT, 340/7–366/7 weeks of gestation), when the benefits of ACS are subtle.DesignPopulation-based, retrospective cohort.SettingOntario, Canada, between 2006 and 2011.PatientsAll live singleton infants born during the LPT period with a minimum 5-year follow-up.InterventionsExposure to ACS prior to 340/7 weeks of gestation.Main outcome measuresSuspected neurocognitive disorder, audiometry testing or visual testing.ResultsOverall, 25 668 infants were eligible for analysis, of whom 2689 (10.5%) received ACS. Infants in the ACS group had lower mean birth weight and higher rates of birth weight <10th percentile, neonatal resuscitation and neonatal intensive care unit admission. At 5 years of age, ACS exposure was associated with an increased risk of suspected neurocognitive disorder (adjusted HR (aHR) 1.12, 95% CI 1.05 to 1.20), audiometry testing (aHR 1.20, 95% CI 1.10 to 1.31) and visual testing (aHR 1.06, 95% CI 1.01 to 1.11).ConclusionIn children born during the LPT period, exposure to ACS prior to 340/7 weeks of gestation is associated with an increased utilisation of the healthcare system related to audiometry and visual testing and suspected neurocognitive disorders by 5 years of age.

Background: The aim of the current study was to assess the fetomaternal effects of oligohydramnios on term pregnancies in a rural tertiary care setup.Methods: A perspective case control hospital-based trial was conducted at Burdwan Medical College and Hospital for a period of one year. Pregnancies at term (37-42 weeks) were included in the study. 103 patients with sonographically diagnosed oligohydramnios were included in the case group. The control group comprised of 103 mothers at term with normal liquor volume. Demographic data and fetomaternal outcome parameters were assessed and compared.Results: There was increased incidence of fetal and perinatal complications including low birth weight, birth asphyxia and NICU admission. There were more perinatal deaths in the case group compared to the control group. Induction of labour, operative delivery, meconium stained liquor and incidence of preeclampsia were also increased in mothers with low AFI.Conclusions: Oligohydramnios is associated with an increased risk of labour and perinatal complications. Adequate antenatal surveillance and intranatal monitoring coupled with correction of underly-ing factors is the mainstay of management.

Objective Pulmonary hemorrhage (PH) is a severe complication in preterm neonates. This study aims to identify risk factors and comorbidities of PH. Study Design A single-center cohort study on medical records including all preterm neonates of <30 weeks' gestational age was conducted in the neonatal intensive care unit of Universitätsklinikum Aachen, Germany. The occurrence of PH served as a primary end point. Gestational age, birthweight, sex, multiple births, intracytoplasmic sperm injection (ICSI), intubation, surfactant, antenatal steroids, intraventricular hemorrhage (IVH), amniotic infection syndrome, and persistent ductus arteriosus were studied as risk factors. Results In this study, 344 preterm neonates were included, of whom 36 suffered from PH (10.5%). The mean time of the first occurrence was the third day of life (standard deviation [SD]: 1.2). On average, the patients suffered from 1.5 incidents (SD: 0.8) of PH, of whom 50% were severe. Preterm neonates born as multiples (95% confidence interval [CI]: 3.1, 26.9) and those who suffered from IVH (95% CI: 2.7, 18.9) had a significantly increased risk of PH. ICSI was not an independent risk factor. Conclusion PH is significantly associated with IVH and multiple births but not with ICSI. The identification of patients at risk allows to apply prophylactic strategies of ventilation and pharmacological treatment.

Since blood transfusion is linked to the magnitude of the surgical procedure, comparing transfused patients to untransfused patients will always be confounded by infection risks due to factors related to the procedure. To control for these factors one must compare patients transfused with red cells from different sources or prepared in a manner which minimize infection risk. Patients transfused with homologous blood have infection rates several fold higher than recipients of equal values of autologous blood undergoing the same operative procedure (20-23). Homologous blood recipients have significantly longer hospital stays attributed to treating infections. The cost of a blood transfusion exceeds the cost of collection, storage and administration because of transfusion's association with length of stay. In this era of cost-containment the association with prolonged stay may ultimately curtail the use of blood. Homologous blood can be filtered to remove donor leukocytes which may be contributing to immune suppression and infection risk. A prospective randomized trial comparing the infection rates among colorectal cancer patients receiving filtered and unfiltered blood has been conducted (9). There were 17 infectious complications among the 56 recipients of whole blood and one infectious complication among the 48 recipients of filtered blood. Infections were prevented by the seemingly simplistic addition of a $25/filter to every bag of blood transfused. These clinical studies are very convincing: homologous blood transfusion is associated with increased risk of infection in every clinical situation examined. In multivariate analyses transfusion was a significant predictor of infection after consideration of other variables measured and in the majority of those studies transfusion was the single most significant factor. Patients receiving homologous blood exhibited an incidence of infectious complications that was approximately four times higher than patients receiving autologous blood. The association of transfusion with infection is found among patients undergoing surgery for cardiac, orthopedic and gastrointestinal disorders and for trauma as well as among unoperated patients transfused for bums and gastrointestinal bleeding. The observation that nosocomial infections are increased in these studies argues strongly that the association of transfusion with infection is not simply a reflection of transfusion as a marker of tissue destruction and contamination. Infections that develop in transfused patients away from the site of trauma or in the absence of trauma, cannot be attributed to the quantity of tissue destroyed or to the degree of bacterial contamination. Filtered blood can remove leukocytes and prevent postoperative infections. Since filtering blood can significantly reduce the incidence of infection among transfused patients, all transfused blood will be passing through filters in the very near future. EXPERIMENTAL STUDIES RELATING BLOOD TRANSFUSION TO INCREASED RISK OF INFECTION Patients are extremely heterogeneous and even in prospective randomized trials, factors which influence patients' participation affect the outcome despite double-blinding and randomization. In animal studies using syngeneic strains with identical housing, lighting, access to food and water, control over the extent of injury, use of antibiotics and exposure to other variables the influence of a single variable such as blood transfusion can be measured. Dr. Waymack's laboratory has intensively studied parameters which interact with transfusion in

Objective: To assess the recurrence of PD catheter migration after the introduction of a walnut ballast. Materials and Methods: Retrospective study from 1999 to 2014 of PD patients followed in Limousin. Were compared two groups: ballast group (patients who benefited from the establishment of stainless steel ballast at the intraperitoneal catheter extremity) with 26 patients and control group with 204 patients. The primary endpoint was the occurrence of an episode catheter’s migration after ballast’s establishment. Secondary objectives were (i) to determine the causal factors leading to the catheter weighting, (ii) to ensure the safety of the procedure on the following criteria: infectious complications, mechanicals complications, epurations criteria, and catheter’s survival. Results: More than one year after the implementation of the ballast, no recurrent migration was observed in 86.6% of cases. It wasn’t found an increased risk of infections (OR = 0.5, 95% CI [0.22, 1.13]) or mechanical complications (OR = 1.77- 95% CI [0.77, 4.05]) between the two groups. The adequation criteria were similar: KT / V total : 2.37 in the control group and 2.28 in the ballast group (p = 0.63). The survival of the ballast catheter was comparable among the two groups (p = 0.983). Three causal factors that led to the ballast were identified: automated peritoneal dialysis (APD) (OR = 0.38, 95% CI [0.16, 0.9]), the failure from the first use of the catheter (OR = 19.48, CI 95 % [7.67, 49.48]) and the incarceration of the omentum (OR = 15.84, 95% CI [5.81, 43.21]). Conclusion: The ballast used in these study appears to prevent recurrence of migration, without any impact in terms of infectious or mechanical complications, or on the dialysis criteria or on catheter’s survival. However this catheter does currently not have an EC authorization

Abstract ObjectiveLate-preterm infants (LPT) are at increased risk for long-term neurodevelopmental sequelaeand iron deficiency. Aim of the study is to assess the positive effect of iron supplementation on neurological development in healthy LPT.DesignWe designed a perspective, randomized placebo-controlled double-blind trial. The newborns were randomized in two groups: thirty-three patients received martial prophylaxis, thirty-three placebo. Every patient was assessed using the Griffith Mental Development Scales (GMDS)-II edition at 12 months of post-conceptional age.SettingThe study was performed at the Neonatology Unit of Fondazione Policlinico Gemelli IRCCS.PatientsSixty-six healthy LPT infants born between 340⁄7 and 366⁄7 weeks of Gestational Age were enrolled in the study.InterventionsOne group received martial prophylaxis from the third week of life to six months of post-conceptional age (2 mg/kg/day of iron pidolate), the other received placebo.Main outcome measuresFifty-two of the enrolled infants were assessed using the GMDS at 12-month of post-conceptional age. Statistical analysis of the mean scores of the Griffith subscales was performed.ResultsThere was a difference in the mean Developmental Quotient (DQ) (p<0.01) between the two groups: Iron Group mean DQ 121.45+10.53 vs Placebo Group mean DQ 113.25+9.70. Moreover, mean scores of the Griffith subscales A, B and D showed significant differences between the two Groups (scale A p<0.05, scale B p<0.02, scale D p<0.01 respectively).ConclusionsOur data show that newborns who received iron supplementation during the first six months of life achieved significantly better neurological outcomes at GMDS than Placebo group.
