Familiar clustering and spreading of hepatitis delta virus infection

1985

The prevalence of hepatitis delta virus (HDV) infection was significantly higher among the relatives of 79 carriers of HBsAg with antibody to HDV (index cases) than among relatives of 111 carriers without serological evidence of HDV infection (controls). Antibody to HDV was found in 45 of the 80 (56%) carriers of HBsAg in families of index cases but only in 2 of 59 (3%) carriers in families of controls (P less than 0.0001). During follow-up new HDV infection developed in 31% of 13 susceptible carriers in families of index cases, but only in 1.2% of 162 susceptible carriers in families of controls (P less than 0.001). None of the family members previously unexposed to the hepatitis B virus h…

The epidemiology of Varicella Zoster Virus infection in Italy

2008

Abstract Background The epidemiological importance of varicella and zoster and the availability of an efficacious and safe vaccine have led to an important international debate regarding the suitability of mass vaccination. The objective of the study was to describe the epidemiology of varicella and zoster in Italy and to determine whether there have been changes with respect to observations provided by an analogous study conducted 8 years ago, in order to define the most appropriate vaccination strategy. Methods A number of data sources were evaluated, a cross-sectional population-based seroprevalence study was conducted on samples collected in 2004, and the results were compared with data…

Four unrelated patients with lubs X-linked mental retardation syndrome and different Xq28 duplications

2010

The Lubs X-linked mental retardation syndrome (MRXSL) is caused by small interstitial duplications at distal Xq28 including the MECP2 gene. Here we report on four novel male patients with MRXSL and different Xq28 duplications delineated by microarray-based chromosome analysis. All mothers were healthy carriers of the duplications. Consistent with an earlier report [Bauters et al. (2008); Genome Res 18: 847-858], the distal breakpoints of all four Xq28 duplications were located in regions containing low-copy repeats (LCRs; J, K, and L groups), which may facilitate chromosome breakage and reunion events. The proximal breakpoint regions did not contain known LCRs. Interestingly, we identified …

The main trends in the palaeodemography of the 7th-18th century population of Latvia

2006

The study represents palaeodemographic research of osteological material of 3304 individuals from the funds of the Anthropological Laboratory of the Institute of History of the University of Latvia in Riga, dating from the 7 th to the 18 th century AD. Compensated life expectancy at birth is varying between 20.3 and 22.2 years during the research period. Crude mortality has changed between 49.3 and 45 %o. In the early period (7 th - 13 th century) there is a significant male prevalence (2.2 - 1.4); female life expectancy at the age of 20 is on average 6.6 years less than for males. This difference decreases to 5.4 years in the 13 th - 18 th century. According to historical demography, femal…

Effects of Heat Waves on Mortality

2013

Heat waves and air pollution are both associated with increased mortality. Their joint effects are less well understood.We explored the role of air pollution in modifying the effects of heat waves on mortality, within the EuroHEAT project. Daily mortality, meteorologic, and air pollution data from nine European cities for the years 1990-2004 were assembled. We defined heat waves by taking both intensity and duration into account. The city-specific effects of heat wave episodes were estimated using generalized estimating equation models, adjusting for potential confounders with and without inclusion of air pollutants (particles, ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide). To …

Hysteroscopic resection of the septum improves the pregnancy rate of women with unexplained infertility: a prospectine controlled trial

2009

Objective: To assess fecundity of infertile women after surgical correction of uterine septum. Design: Prospective controlled trial. Setting: Three academic infertility clinics. Patient(s): Forty-four women affected by septate uterus and otherwise unexplained infertility represented the study group (group A), and 132 women with unexplained infertility were enrolled as control subjects (group B). Intervention(s): Hysteroscopic metroplasty was performed in group A, and group B was managed expectantly. All women were followed-up for 1 year without any other intervention. Main Outcome Measure(s): Fecundity rate was calculated as the number of pregnancies per 100 person-months Result(s): Pregnan…

Replication of interleukin 23 receptor and autophagy-related 16-like 1 association in adult- and pediatric-onset inflammatory bowel disease in Italy.

2008

AIM: To investigate gene variants in a large Italian inflammatory bowel disease (IBD) cohort, and to analyze the correlation of sub-phenotypes (including age at diagnosis) and epistatic interaction with other IBD genes. METHODS: Total of 763 patients with Crohn's disease (CD, 189 diagnosed at age < 19 years), 843 with ulcerative colitis (UC, 179 diagnosed < 19 years), 749 healthy controls, and 546 healthy parents (273 trios) were included in the study. The rs2241880 [autophagy-related 16-like 1 (ATG16L1)], rs11209026 and rs7517847 [interleukin 23 receptor (IL23R)], rs2066844, rs2066845, rs2066847 (CARD15), rs1050152 (OCTN1), and rs2631367 (OCTN2) gene variants were genotyped. RESULTS: The f…

Maternal anxiety following delivery, early infant temperament and mother's confidence in caregiving.

2015

AbstractA mother’s emotional state is a well-known environmental factor that relates to the development of infant temperament. However, some relevant issues have not yet been fully explored. The current study examines the influence of determined maternal, contextual and perinatal variables on infant temperament and the mother’s confidence in caregiving during the first weeks of life. A prospective study was carried out in three-hundred and seventeen newborns and their mothers. Perinatal and socio-demographic variables were recorded. The mother’s anxiety and mood were measured in the first days after childbirth and again at 8 weeks. Infant temperament and the mother’s confidence in caregivin…

Oxidative stress markers at birth: Analyses of a neonatal population

2015

In order to further understand neonatal stress and, thus, control it efficaciously, there is a need for more information on the manifestations of stress at the molecular level in the newborn, with particular regard to oxidants, and anti-oxidant and anti-stress mechanisms, including mitochondrial heat shock protein-chaperones such as Hsp60. We investigated patterns of anti-oxidants, biomarkers of oxidative stress, and Hsp60 levels in sera from newborns and found significant associations between glutathione (GSH) levels and gestational age, delivery modality, and lipid hydroperoxydes (LOOH) level. LOOH levels and spontaneous (vaginal) delivery were independently associated with increased GSH …
