Abstract
The goal of this study was to evaluate changes in plasma human immunodeficiency virus (HIV) RNA concentration [viral load (VL)] and CD4+ percentage (CD4%) during 6-12 weeks postpartum (PP) among HIV-infected women and to assess differences according to the reason for receipt of antiretrovirals (ARVs) during pregnancy [prophylaxis (PR) vs. treatment (TR)]. Data from a prospective cohort of HIV-infected pregnant women (National Institute of Child Health and Human Development International Site Development Initiative Perinatal Study) were analyzed. Women experiencing their first pregnancy who received ARVs for PR (started during pregnancy, stopped PP) or for TR (initiated prior to pregnancy and/or continued PP) were included and were followed PP. Increases in plasma VL (> 0.5 log10) and decreases in CD4% (> 20% relative decrease in CD4%) between hospital discharge (HD) and PP were assessed. Of the 1,229 women enrolled, 1,119 met the inclusion criteria (PR: 601; TR: 518). At enrollment, 87% were asymptomatic. The median CD4% values were: HD [34% (PR); 25% (TR)] and PP [29% (PR); 24% (TR)]. The VL increases were 60% (PR) and 19% (TR) (p < 0.0001). The CD4% decreases were 36% (PR) and 18% (TR) (p < 0.0001). Women receiving PR were more likely to exhibit an increase in VL [adjusted odds ratio (AOR) 7.7 (95% CI: 5.5-10.9) and a CD4% decrease (AOR 2.3; 95% CI: 1.6-3.2). Women receiving PR are more likely to have VL increases and CD4% decreases compared to those receiving TR. The clinical implications of these VL and CD4% changes remain to be explored.

Abstract
The prevalence and epidemiology of important viral (equine influenza virus [EIV], equine herpesvirus type 1 [EHV-1] and EHV-4) and bacterial (Streptococcus equi subspecies equi) respiratory pathogens shed by horses presented to equine veterinarians with upper respiratory tract signs and/or acute febrile neurological disease were studied. Veterinarians from throughout the USA were enrolled in a surveillance programme and were asked to collect blood and nasal secretions from equine cases with acute infectious upper respiratory tract disease and/or acute onset of neurological disease. A questionnaire was used to collect information pertaining to each case and its clinical signs. Samples were tested by real-time PCR for the presence of EHV-1, EHV-4, EIV and S equi subspecies equi. A total of 761 horses, mules and donkeys were enrolled in the surveillance programme over a 24-month study period. In total, 201 (26.4 per cent) index cases tested PCR-positive for one or more of the four pathogens. The highest detection rate was for EHV-4 (82 cases), followed by EIV (60 cases), S equi subspecies equi (49 cases) and EHV-1 (23 cases). There were 15 horses with double infections and one horse with a triple infection. The detection rate by PCR for the different pathogens varied with season and with the age, breed, sex and use of the animal.

Abstract
INTRODUCTION BK polyomavirus (BKV) reactivation characterized by active viruria occurs in 23%-57% of renal allograft recipients and BKV-associated nephropathy in as many as 8% of renal allograft recipients. Only a few cases of nephritis have been attributed to JC polyomavirus (JCV) with limited information about JCV replication and its impact on graft function and survival of kidney transplant patients. We sought to determine the prevalence of BKV and JCV replication, the risk factors associated with viral reactivation, and their implications for the development of polyomavirus nephropathy (PVN) among renal transplant patients. MATERIALS AND METHODS The study included 186 kidney transplant recipients who were transplanted between 2005 and 2009 with a 1-year follow-up. If the urine polymerase chain reaction (PCR) was positive, we performed a PCR on blood. If this was positive or renal dysfunction was present, we performed a renal biopsy. RESULTS Viruria was positive in 72 cases (39%) and viremia in 12 (6.5%); including, 3 patients (1.6%) who developed PVN. In the patients with viruria, BKV was detected in 47% and JCV in 46%; both were detected in 7%, although the combination of viremia and nephropathy were caused by BKV in all cases. CONCLUSION In renal transplant patients, the incidence of BKV and JCV viruria was similar, although in our series the JCV serotype did not cause viremia or PVN. Our experience suggested that JCV did not have the ability to cause PVN.

Abstract
According to several authors, Trypanosoma evansi is a monomorphic trypanosome found exclusively in slender intermediate forms, although additional studies have revealed that many strains present stumpy forms on rare occasions. In a recent T. evansi outbreak in mainland Spain, several atypical forms were observed in blood smear examinations. Molecular procedures were then necessary to confirm the causal agent. Morphological and biometric measures were taken to characterize the different forms of T. evansi. In contrast to published information, the results of this study would indicate that biometrically distinct T. evansi could also be found in the same farm and even in the same animal species. These data could be useful for many trypanosomes endemic areas of the world where molecular methods are not commonly available.

Abstract
Coxiella burnetii is the causative agent of Q fever, a zoonosis with worldwide occurrence. In the Canary Islands, the overall seroprevalence in humans has been estimated to be 21.5%. Gran Canaria island concentrates the highest ruminant population in the archipelago and the prevalence of the human infection is 23.5%. To evaluate the seroprevalence in livestock and the affected areas in Gran Canaria island, a total of 1249 ruminants were randomly selected for this study (733 goats, 369 sheep and 147 cattle). The samples were evaluated using an indirect ELISA Kit. The results showed seroprevalences of 60.4%, 31.7% and 12.2% in goats, sheep and cattle, respectively. Based on these results, Q fever could be considered as endemic in Gran Canaria island. Sanitary measures should be taken at the farm level to minimize the risk of exposure of C. burnetii to humans.

Abstract
BACKGROUND In Spain, the number of ideal kidney transplant donors has fallen, with at the same time an increase in the number of older recipients on the waiting list. AIM To analyze the results of expanded criteria cadaveric donor kidney transplants into older recipients using grafts selected by kidney biopsy. PATIENTS AND METHODS We studied 360 kidney transplant recipients who had been followed to December 2009: 180 in the study group and 180 in a control group composed of younger patients who received grafts from non-expanded criteria donors between 1999 and 2006. A paraffin-embedded kidney biopsy was evaluated by the percentages of sclerosed glomeruli, arteriolar hyalinosis, intimal wall thickening, interstitial fibrosis, and tubular atrophy. RESULTS Significant differences were observed in donor age (63.50±5.46 vs 31.90±13.29 years; P<.001) and recipient age (58.40±8.80 vs 40.71±13.23 years; P<.001). Donor renal function was significantly worse among the expanded criteria group (90.80 vs 108.11 mL/min/1.73 m2; P=.006), remaining so over time in the recipient (at 1 year: 42.08 vs 63.71 [P<.001]; at 3 years: 41.25 vs 62.31 [P<.001], and at 7 years: 38.17 vs 64.18 [P<.001]). Censored 7-year graft survivals were 73% versus 87% (P<.001) with similar patient survivals (90.5% vs 95%; P=.39). CONCLUSIONS Selection of expanded criteria donors by kidney biopsy resulted in good renal function as well as graft and patient survivals at 7 years in older recipients.

Abstract
Congenital tuberculosis (TB) remains a rare disease but is fatal if untreated. Early detection is difficult because of the non-specific nature of the symptoms in TB during pregnancy and infancy. This report summarizes a case of congenital TB in a very premature infant, born at 25 weeks gestation. Miliary TB was diagnosed in the mother when the neonate was 20 days old. Antituberculous therapy allowed a rapid improvement in the mother. The infant died at 27 days old. A Beijing genotype strain of Mycobacterium tuberculosis was isolated both in the mother, from pulmonary and urine specimens, and in the infant, from peritoneal fluid.

Abstract
Eukaryotic chromatin is a highly structured macromolecular complex of which DNA is wrapped around a histone-containing core. DNA can be methylated at specific C residues and each histone molecule can be covalently modified at a large variety of amino acids in both their tail and core domains. Furthermore, nucleosomes are not static entities and both their position and histone composition can also vary. As a consequence, chromatin behaves as a highly dynamic cellular component with a large combinatorial complexity beyond DNA sequence that conforms the epigenetic landscape. This has key consequences on various developmental processes such as root and flower development, gametophyte and embryo formation and response to the environment, among others. Recent evidence indicate that posttranslational modifications of histones also affect cell cycle progression and processes depending on a correct balance of proliferating cell populations, which in the context of a developing organisms includes cell cycle, stem cell dynamics and the exit from the cell cycle to endoreplication and cell differentiation. The impact of epigenetic modifications on these processes will be reviewed here.

Abstract
CONTEXT Zinc-alpha2-glycoprotein (ZAG) is a soluble protein similar to the class I major histocompatibility complex heavy chain, which has been implicated in lipid catabolism. We hypothesized that ZAG mRNA expression in adipose tissue may be linked with lipolytic and adipokine gene expression and have a close relationship with clinical phenotype. OBJECTIVES The objective of the study was to analyze ZAG gene expression in human adipose tissue from lean and obese subjects. ZAG circulating plasma levels and its relationship with cardiometabolic risk factors were also studied. DESIGN Seventy-three Caucasian (43 male and 30 female) subjects were included. Plasma and adipose tissue [sc (SAT) and visceral (VAT)] from the same patient were studied. mRNA of PPARgamma, hormone-sensitive lipase (HSL), adipose triglyceride lipase, adiponectin, omentin, visfatin, and ZAG were quantified. Plasma concentrations of ZAG were determined with ELISA. RESULTS ZAG plasma levels showed a negative correlation with insulin (r = -0.39; P = 0.008) and the homeostasis model assessment for insulin resistance index (r = -0.36; P = 0.016). No differences in ZAG circulating levels according to body mass index classification were observed. ZAG expression in SAT was significantly reduced in overweight and obese individuals compared with lean subjects (P < 0.001 and P = 0.007, respectively). ZAG mRNA expression in both SAT and VAT depots were negatively correlated with many clinical and metabolic cardiovascular risk factors. After multiple linear regression analysis, SAT ZAG was mainly predicted by adiponectin mRNA expression (B = 0.993; P < 0.0001) and plasma triglyceride levels (B = -0.565; P = 0.006). VAT ZAG expression was predicted by adiponectin expression (B = 0.449; P < 0.0001), and HSL VAT expression (B = 0.180; P = 0.023). CONCLUSIONS The present study provides evidence of a role of ZAG gene in adipose tissue metabolism, with a close association with adiponectin gene expression in sc and visceral fat.
