Abstract
Mitochondrial DNA (mtDNA) population data for forensic purposes are still scarce for some populations, which may limit the evaluation of forensic evidence especially when the rarity of a haplotype needs to be determined in a database search. In order to improve the collection of mtDNA lineages from the Iberian and South American subcontinents, we here report the results of a collaborative study involving nine laboratories from the Spanish and Portuguese Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) and EMPOP. The individual laboratories contributed population data that were generated throughout the past 10 years, but in the majority of cases have not been made available to the scientific community. A total of 1019 haplotypes from Iberia (Basque Country, 2 general Spanish populations, 2 North and 1 Central Portugal populations), and Latin America (3 populations from São Paulo) were collected, reviewed and harmonized according to defined EMPOP criteria. The majority of data ambiguities that were found during the reviewing process (41 in total) were transcription errors confirming that the documentation process is still the most error-prone stage in reporting mtDNA population data, especially when performed manually. This GHEP–EMPOP collaboration has significantly improved the quality of the individual mtDNA datasets and adds mtDNA population data as valuable resource to the EMPOP database (www.empop.org).

Abstract
INTRODUCTION In this study, we attempt to find out the percentage of uninfected infants born to HIV-infected women and exposed in-utero and perinatally to Antiretroviral Treatment (ART) that show high lactate levels, or any other mitochondrial damage markers (such as hypertransaminasaemia or hyperamylasaemia), during the first three months of age. We shall also establish whether certain drugs used in-utero are associated with higher lactate, transaminase or amylase levels. METHODS We analysed the available data from 623 uninfected infants born in the Spanish FIPSE cohort that were born in the period 2000-2005. The normal values for lactate, transaminases and amylase were set according to AIDS Clinical Groups Trials toxicity tables for infants. RESULTS The percentages of children with high lactate levels at 0.5; 1.5 and 3 months of age were 48%, 51.4% and 43% among those infants with available data. Respectively, the percentages of children with high AST values were 13.2; 10.4 and 17.2%. The values for high ALT were 3.3%; 3.4% and 5%. The percentages for hyperamylasaemia were 0%; 0.6% and 2.6%. We found no significant difference among the drugs used in utero for the four analysed biochemical markers along the first three months of age. CONCLUSIONS We have found a high proportion of hyperlactataemia among infants exposed in-utero to ART, as shown in other cohorts of similar characteristics. No morbidity or mortality was communicated to the cohort analysis group. No ART drug among those used in-utero was statistically associated with a higher proportion of high lactate levels in these infants.

Abstract
INTRODUCTION Recent reports show that Antiretroviral Treatment (ART) during pregnancy does not affect somatic growth of children born to HIV-infected mothers, are reassuring. The aim of this study is to perform an anthropometric analysis of the uninfected children followed in the Spanish FIPSE cohort during their first 18 months of life, and to describe the possible risk factors during pregnancy that may influence low birth weight. METHODS The FIPSE cohort includes 8 public hospitals in Madrid, and prospectively follows children born to HIV-infected women at these hospitals. We collected data on 601 uninfected children, following standardised protocols, during their first 2 years of life. A P value<0.05 was considered statistically significant. Data from the Pablo Orbegozo Foundation were used to compare the means of our population with the standard weight, longitude an occipitofrontal circumference (OFC) of the Spanish population during the first 18 months of life. RESULTS The mean weight was 2766g (+/-590), and 2967g (+/-427) when premature neonates were excluded. The proportion of Intrauterine Growth Restriction among non- premature neonates was 19.8% (95% CI: 16.3-23.8). Children born to mothers that used illicit drugs weighed less: 2752g (+/-325) vs. 3002g (+/ 435), P<0.001, as did children born to mothers who smoked during pregnancy: 2842g (+/-363) vs. 3018g (+/-444), P>0.001. Maternal anaemia did not influence the low birth weight of the children when premature neonates were excluded. We found no statistically significant differences depending on the ART received during pregnancy. Children born to mothers who had CD4 > 500 cell /mm were heavier (2834g +/-503) than those whose mothers had CD4 of less than 200 cell/mm (2565g +/-702), P=0.008. These differences disappeared when premature neonates were excluded. Children born to mothers with undetectable viral load were heavier (2866g +/-532 vs. 2704g +/-588, P=0.005), but these differences also disappeared when the prematures were excluded from the analysis. Mean weight, length, and OFC of our population at birth (excluding premature neonates) were lower than the Spanish standards. (z for weight=-0.83; z for length =-1.02; z for OFC=-1.00), but these differences are not statistically significant and disappear at 18 months of age (z for weight=-0.08; z for height=-0.32; z for OFC=-0.31). The type of ART did not have any significant influence. DISCUSSION There is a very significant difference between the weight of the children born to mothers addicted to illicit drugs and the rest of the children. Similarly, the weight of the children born to smoking mothers is significantly lower. There was no association between maternal anaemia and the type of ART. The children of our population have lower weights, length and OFC at birth, but this may due to the high number of scheduled caesarean births, practised at 38 weeks of pregnancy (54.5%). Our children catch-up with anthropometric measurements during the first and second year of life, and these are similar to Spanish standards at 18 months old.

Abstract
As pollination is a critical process in both human-managed and natural terrestrial ecosystems, pollinators provide essential services to both nature and humans. Pollination is mainly due to the action of different insects, such as the bumblebee and the honeybee. These important ecological and economic roles have led to widespread concern over the recent decline in pollinator populations that has been detected in many regions of the world. While this decline has been attributed in some cases to changes in the use of agricultural land, the effects of parasites could play a significant role in the reduction of these populations. For the first time, we describe here the presence of Nosema ceranae, an emerging honeybee pathogen, in three species of Argentine native bumblebees. A total of 455 bumblebees belonging to six species of genus Bombus were examined. PCR results showed that three of the species are positive to N. ceranae (Bombus atratus, Bombus morio and Bombus bellicosus). We discuss the appearance of this pathogen in the context of the population decline of this pollinators.

Abstract
INTRODUCTION Mother-to-Child HIV transmission is now just 1% in western countries, due to prevention measures. Antiretroviral Treatment (ART) drugs do have adverse effects, anaemia and myelosupression caused by cidovudina being the most commonly observed effects. In the present study, we have analysed the proportion and characteristics of congenital malformations (CM) or birth defects (BD) in a cohort of uninfected children born to HIV-infected women. METHODS A total of 623 uninfected children belonging to the FIPSE cohort were followed up according to standardised protocols. This cohort includes 8 public hospitals from Madrid and follows up HIV-infected pregnant women and their children. Children were classified according to prematurity, ethnic origin, birth weight, withdrawal syndrome, in-utero treatment. Birth defects were described and defined according to the EUROCAT, the European registry for BD. Mild errors of morphogenesis were excluded from the analysis. Categorical variables were compared with the X(2) or the Fisher test. RESULTS A total of 78% (486) of the mothers were of Caucasian origin; 18.8% (117) used some illicit drug (heroine, cocaine or methadone) during gestation; 51 mothers (8.1%) received no ART, 10 (1.6%) received monotherapy and 469 (75.3%) received HAART. BD were seen in 52 children, with the most frequent being genitourinary and cardiological. Anaemia in the first trimester was an associated risk for BD (17.9% vs. 8.1%, P = 0,04). Similarly, mothers who used any illicit drug (plus methadone), had a slightly higher risk for BD in their offspring (13.8% vs. 7.6%, P = 0,04) There was no increased risk for BD significantly associated with any of the in-utero used antiretrovirals, although Nevirapine use in-utero showed a protective effect. Children born to mothers who received ART in the first trimester had the same rate of BD (7.4%) as those whose mothers started ART in the second trimester (8.8%), P = 0,67. CONCLUSIONS The proportion of BD that we have observed seems higher than those shown in other European teratogenicity studies and also higher than those shown in cohorts with HIV and antiretroviral exposed infants. This may be due to the fact that our series show the results of an active surveillance system (that includes ultrasound), where BD classically appear in a higher proportion. Immunovirological characteristics of the mother did not influence the proportion of BD, but anaemia in the fist trimester and the use of illicit drugs (or methadone) did. No specific antiretroviral drug was associated with an increase in BD, although Nevirapine showed a possible protective effect in the statistical analysis. Mothers who started antiretrovirals in the first trimester do not have more BD in their offspring than mothers who started on antiretrovirals later on.

Abstract
To assess the efficacy of exemestane as neoadjuvant treatment, 55 postmenopausal women (mean age: 76 years; range: 66-86) with oestrogen-positive non-metastatic breast tumour and ineligible for conservative surgery were recruited into this phase II trial to receive oral exemestane (25 mg day(-1)) for 6 months. Tumour response was evaluated by clinical examination, mammography and breast ultrasound every 2 months (RECIST criteria). Overall clinical response to treatment was observed in 33/54 patients (61.1%; 95% CI: 48.1-74.0). Radiological responses in 45 evaluable patients were partial response in 23, stable disease in 21 and disease progression in one. Median time to surgery from the commencement of treatment was 7 months; conservative surgery in 24 patients (55.8%) and mastectomy in 19 patients (34.5%); no surgery (patient choice or considered not suitable by attending physician) in 12 patients. Pathologic complete response was observed in breast and axilla in one patient (2.3%) and different forms of persistent disease in 23 (53.5%) patients. Treatment tolerance was good. No patient withdrew from the study because of toxic events. We conclude that exemestane as a primary treatment is feasible and very active in elderly patients with large-sized breast cancer tumour. Conservative surgery is feasible in responding patients. No severe adverse events were detected. The optimal hormonal treatment schedule remains to be determined.

Abstract
BACKGROUND Lepisma saccharina (silverfish) is a common insect which is often found in human dwellings. Our aim was to determine the IgE antibody pattern to this arthropod in children with allergic respiratory symptoms. METHODS The individual sera and a pool of selected sera of 45 children with asthma and/or rhinitis were used for an immunoblotting test with an extract of Lepisma saccharina; an immunoblotting inhibition test was performed with extracts of L. saccharina, D. pteronyssinus and cockroach. RESULTS Between one and ten IgE binding bands were found in the sera of patients. The immunoblotting pattern was clearly different from that of D. pteronyssinus. Inhibition was found with D. pteronys-sinus and cockroach, which proves cross-reactivity between extracts. CONCLUSION Allergenicity of Lepisma is demonstrated through in vitro tests. A pathogenic role still remains to be proved, but it should be considered in respiratory allergy, due to primary sensitisation to Lepisma, or to cross-reactivity with other indoor allergens.

Abstract
BACKGROUND A previous study using cinacalcet, as compared to vitamin D alone, showed a better reduction response of PTH levels and a significant diminution of secondary effects. The objective of present study was to evaluate the additional cost of adding cinacalcet to the standard treatment of patients with severe secondary hyperparathyroidism (SHPT) taking into account the treatment goals achieved. METHODS 12 month prospective study of 23 patients with severe SHPT. Two treatment regimens were considered: standard treatment (m 0) and standard treatment plus cinacalcet (m 12). Four consequences of inadequate control of SHPT were registered: parathiroid hormone (PTH), Calcium (Ca), Phosphorus (P) and the Ca x P product serum levels. Treatment effectiveness was measured as percentage of patients who achieved treatment goal according to each indicator: PTH < 800 pg/mL, PTH between 150 and 300 pg/mL, Calcium < 9.5 mg/dL, Phosphorus < 5.5 mg/dL, and Ca x P product < 55. Annual and monthly costs were calculated for both treatment regimens using Spanish 2007 tariffs, and taking into account the dose reduction in some other treatments. Results are presented as incremental costs and cost per patient who achieved treatment goal. RESULTS At 12 month it was observed a higher percentage of patients who achieved simultaneously the 4 therapeutic goals with respect to basal moment, from 0% to 52.1%. Cinacalcet allowed to save costs in concomitant drugs, achieving a total saving of 149 euros per patient and month. At 12 month, Cinacalcet achieved a reduction of percentage of patients with PTH > 800 pgr/mL with half of costs than standard treatment (651.35 euros vs 1363.68 euros). It was not possible to calculate the cost for PTH indicator since at the study onset, there was no patient who achieved a level between 150 and 300 pg/mL. Cinacalcet allowed reaching treatment goals in Calcium, Phosphorus and Ca x P product in a more cost-effective way (2164.2 euros vs 2684.8 euros). CONCLUSIONS Although Cinacalcet is expensive,p atients treated with Cinacalcet showed a minor cost per patient who achieved treatment goal than patients without Cinacalcet. The ability of cinacalcet to reduce PTH secretion, along with the reductions in the serum Ca, P, and Ca x P product, provides an alternative to the traditional treatment paradigm, and should be a welcomed addition in the management of SHPT.

Abstract
We report the results of the seventh edition of the GEP-ISFG mitochondrial DNA (mtDNA) collaborative exercise. The samples submitted to the participant laboratories were blood stains from a maternity case and simulated forensic samples, including a case of mixture. The success rate for the blood stains was moderate ( approximately 77%); even though four inexperienced laboratories concentrated about one-third of the total errors. A similar success was obtained for the analysis of mixed samples (78.8% for a hair-saliva mixture and 69.2% for a saliva-saliva mixture). Two laboratories also dissected the haplotypes contributing to the saliva-saliva mixture. Most of the errors were due to reading problems and misinterpretation of electropherograms, demonstrating once more that the lack of a solid devised experimental approach is the main cause of error in mtDNA testing.

Abstract
The aim of this study was to determine the level of asthma control and the concordance between physicians' and patients' opinions and the real patients' situation. A total of 777 subjects (55% female) with asthma were recruited. The study comprised a 4-week follow-up period, during which subjects completed a diary recording peak expiratory flow (PEF), symptoms, and use of rescue medication. At the end, both physicians and patients rated asthma control status. The level of control was evaluated using a composite measure. Agreement among subjective assessments of asthma control by patients and physicians and objective evaluation with the composite measure was assessed through kappa scores. A total of 518 (67%) patients had "not well-controlled asthma," being the remaining "totally controlled" (8%) or "well-controlled" (25%). "Not well-controlled asthma" was more frequent in smokers (82%) than in ex-smokers (70%) or in non-smokers (62%; p=0.0002). Kappa scores between patients' and physicians' opinions and the real patients' status were 0.02 (95% CI, 0.01-0.05) and 0.07 (95% CI, 0.03-0.09), respectively. In conclusion, current level of asthma control is suboptimal for a majority (67%) of patients in Spain. Besides, asthma control is worse in smokers. Neither patients' nor physicians' opinions agree with patients' real situation. Both patients and physicians accept as normal a suboptimal status of their disease.

Abstract
Nuclear mitochondrial insertions (NUMTs) are sequences homologous to mtDNA, which are present throughout the human nuclear genome. The possibility that these sequences may be accidentally amplified in reactions directed to mtDNA has been raised and evaluated by different groups and by different means. Despite that, data is still missing on the specificity of PCRs in routine procedures in what concerns contamination with nuclear mtDNA insertions (NUMTs). In this work, we performed PCR sequencing reactions with primers directed either to mitochondrial or to NUMT DNA with different annealing temperatures and in different tissues. We observed that (a) contamination with NUMTs depends on the sample and tissue, and (b) employing routine techniques, there is no risk of co-amplification. Only when mtDNA is almost completely removed from the samples does the number of NUMT copies exceed mitochondrial sequences, i.e., only in samples with virtually no mtDNA, such as those resulting from preferential semen lysis, is there a risk of accidental amplification of NUMTs. We suggest that to evaluate a possible co-amplification of NUMT DNA, it is more relevant to take into account sample processing and original tissue of the samples, and consequently the relative proportions of NUMT and mtDNA, rather than the presence of NUMTs by itself, irrespectively of its proportion.

Abstract
BACKGROUND AcroQol is a disease-generated questionnaire, developed to assess quality of life (QOL) in patients with acromegaly. We have previously demonstrated severely impaired QOL in patients with acromegaly and the value of AcroQol in measuring QOL in a cross-sectional study compared with the non-disease-specific generic tools 'Psychological general wellbeing schedule' (PGWBS) and EuroQol (EQ-5D), and the disease-specific signs and symptoms score (SSS). AIM, SUBJECTS AND METHODS: We re-evaluated these tools in a longitudinal study of 56 of the previously reported patients (33 male, mean age 55 +/- 15 years), in order to determine change in QOL over time and the effect of different treatment modalities. Data were analysed using Spearman's correlation tests. RESULTS Baseline median IGF-I was 354 ng/ml (range 48-899) and at re-evaluation 217 ng/ml (60-594) (P < 0.001) [median time interval 608 days (113-1136)]. Analysis of change in IGF-I levels and AcroQol scores demonstrated a significant negative correlation (i.e. a reduction in IGF-I being associated with improved overall QOL (r = -0.36, P = 0.006). Significant negative correlations were also seen in the physical (r = -0.33, P = 0.01), psychological (r = -0.37, P = 0.005) and appearance (r = -0.42, P = 0.001) AcroQol subdomains. No correlations were seen between change in IGF-I and change in overall PGWBS score or subdomains, SSS or EQ-5D. CONCLUSIONS In summary, of the tools studied we have demonstrated AcroQol to be uniquely capable of detecting changes in QOL associated with treatment-induced improvement in the main biochemical marker of disease activity in patients with acromegaly. Further studies are required to evaluate the long-term biological significance of the changes seen in AcroQol.

Abstract
A multiplex PCR-based method, in which two small-subunit rRNA regions are simultaneously amplified in a single reaction, was designed for parallel detection of honeybee microsporidians (Nosema apis and Nosema ceranae). Each of two pairs of primers exclusively amplified the 16S rRNA targeted gene of a specific microsporidian. The multiplex PCR assay was useful for specific detection of the two species of microsporidians related to bee nosemosis, not only in purified spores but also in honeybee homogenates and in naturally infected bees. The multiplex PCR assay was also able to detect coinfections by the two species. Screening of bee samples from Spain, Switzerland, France, and Germany using the PCR technique revealed a greater presence of N. ceranae than of N. apis in Europe, although both species are widely distributed. From the year 2000 onward, statistically significant differences have been found in the proportions of Nosema spp. spore-positive samples collected between and within years. In the first period examined (1999 to 2002), the smallest number of samples diagnosed as Nosema positive was found during the summer months, showing clear seasonality in the diagnosis, which is characteristic of N. apis. From 2003 onward a change in the tendency resulted in an increase in Nosema-positive samples in all months until 2005, when a total absence of seasonality was detected. A significant causative association between the presence of N. ceranae and hive depopulation clearly indicates that the colonization of Apis mellifera by N. ceranae is related to bee losses.

Abstract
Here we describe a multistep solid-phase synthetic approach for the addition of amino acid residues to both the C- and N-termini of a phenylstatine core, yielding a library aimed at the development of structure-activity relationships in the S2 and S2' regions of the aspartyl proteases. Optimization of the synthetic strategy was performed on the basis of the in situ analysis of the compounds bound to the solid support through high-resolution magic angle spinning NMR Spectroscopy (HR-MAS NMR).

Abstract
BACKGROUND The objective of this study was to determine differences in EBC pH between samples obtained by RTube and EcoScreen, and to identify the effect of storage at -80 degrees C on the pH values. METHODS Twenty-three nonsmoking subjects with asthma or allergic rhinitis or without respiratory disease performed two sequential exhaled breath condensate (EBC) collections, using the RTube collection system and the EcoScreen condenser. EBC pH was measured immediately after collection and after storage at -80 degrees C for 8 weeks, without deaeration and repeated following deaeration with Argon. RESULTS In EBC samples without deaeration, the EcoScreen pH values were significantly higher than the RTube pH values (mean difference, 0.32; 95% CI, 0.21-0.44, P < 0.0001). In deaerated EBC samples, the EcoScreen pH values were also significantly higher than the RTube pH values (mean difference, 0.12; 95% CI, 0.01-0.25, P=0.04). For both EBC collection systems, storage for 8 weeks had a significant influence on pH of nondeaerated samples. CONCLUSIONS The present study demonstrates that EBC pH value is dependent on the collection device used and that the storage for 8 weeks had a significant influence on the pH of samples analyzed without deaeration.
