ABSTRACT

Long-term observation of patients with ANCA-associated vasculitis (AAV) allows the identification of different longitudinal patterns of ANCA levels during follow-up. This study aimed to characterize these patterns and to determine their prognostic significance. All ANCA determinations performed in two university hospitals during a 2-year period were retrospectively reviewed. Patients were included in the analysis if they had high titers of anti-myeloperoxidase (anti-MPO) or anti-proteinase 3 (anti-PR3) antibodies at least once, ≥ 5 serial ANCA determinations and AAV diagnosed by biopsy or American College of Rheumatology (ACR) classification criteria. Patients' time-course ANCA patterns were classified as monophasic, remitting, recurrent or persistent. Associations between ANCA patterns and prognostic variables (relapse rate and renal outcome) were analysed by univariate and multivariate statistics. A total of 99 patients [55 with microscopic polyangiitis (MPA), 36 with granulomatosis with polyangiitis (GPA) and eight with eosinophilic granulomatosis with polyangiitis (EGPA)] were included. Median follow-up was 9 years. Among patients diagnosed with MPA or GPA, recurrent or persistent ANCA patterns were associated with a higher risk of clinical relapse [hazard ratio (HR) = 3·7, 95% confidence interval (CI) = 1·5-9·1 and HR = 2·9, 95% CI = 1·1-8·0, respectively], independently of clinical diagnosis or ANCA specificity. In patients with anti-MPO antibodies, the recurrent ANCA pattern was associated with worsening renal function [odds ratio (OR) = 5·7, 95% CI = 1·2-26·0]. Recurrent or persistent ANCA patterns are associated with a higher risk of clinical relapse. A recurrent ANCA pattern was associated with worsening renal function in anti-MPO-associated vasculitis.

ABSTRACT

We present the case of a 34-year-old male patient employed for 8 years in a company manufacturing and packaging animal feed. The patient developed occupational asthma to dry Gammarus powder. The diagnosis was confirmed by specific bronchial provocation test. The determination of specific IgE antibodies was positive for Pen m 4, a sarcoplasmic calcium binding protein, with a level of 6.7 ISU-E. The sensitization to Pen m 4 described here may identify a new allergen causing occupational asthma in these workers.

ABSTRACT

BACKGROUND: Emergency contraception (EC) is an effective postcoital contraceptive method for reducing the risk of unwanted pregnancy after unprotected intercourse. The estimated effectiveness of EC is between 70 and 89% if taken within 72 h following intercourse. Most of the studies carried out in Spain are quantitative and from the perspective of health professionals. In this study, we intend to explore the knowledge of, attitudes towards and discourse regarding the use of EC in women aged 15 to 25 years. METHODS: Sample: A qualitative study including in-depth interviews with 19 women between 15 and 25 years of age was performed. INCLUSION CRITERIA: Participants were natives of Spain or of a Latin American country. Segmentation criteria: Participants had experience in the use of EC. DATA COLLECTION: Participants were selected by health care informants and by the snowball technique among university students. DATA ANALYSIS: A thematic analysis was performed. Preliminary analyses were made during the course of the field work to adapt the script and to assess data saturation. A preliminary code tree was developed by two researchers, and the coding of the text was done with the Atlas.ti 5.0 software. RESULTS: EC is perceived positively by women. They do not express issues with taking it, although some feel guilty. The reason for taking EC is to avoid unwanted pregnancy and abortion. Women also feel that EC should be used in moderation. False beliefs and misconceptions regarding EC are held: EC delivers an excess of hormones, induces abortion and causes severe side effects. Women mention that the health professionals who provide EC have moral beliefs. Women use it because of condom breakage associated with their first coital relations. CONCLUSIONS: The results of this study have public health implications: The sexual-affective health education received by young people should incorporate clear information about the mechanism of action of the EC pill and its side effects together with empowerment strategies addressing guilt and moralistic messages. Programmes and training activities for health professionals must be designed to prevent the communication of inappropriate messages such as those that exaggerate the side effects of EC and those that promote fear and guilt, because they represent a barrier to the responsible use of this medication.

ABSTRACT

Several studies have associated telomere shortening with alterations in reproductive function. The objective of the present study was to determine telomere length (TL) in spermatozoa selected by either density-gradient centrifugation (DGC) or swim-up. The analysis of TL was performed using quantitative fluorescent in situ hybridisation (qFISH) using PNA probes in combination with a chromatin decompaction protocol in sperm cells. Results of TL were 24.64 ± 5.00 Kb and 24.95 ± 4.60 Kb before and after DGC, respectively, and 19.59 ± 8.02 Kb and 20.22 ± 5.18 Kb before and after swim-up respectively. Sperm selected by DGC or swim-up did not show any significant differences in TL as compared to nonselected sperm (p > .05). Negative correlations between TL and sperm motility (r = -.308; p = .049) and concentration (r = -.353; p = .028) were found. Furthermore, exposure of sperm to increasing concentrations of hydrogen peroxide during incubation resulted in a reduction in TL. These data indicate that oxidative stress may be one of the main factors involved in the reduction of TL in sperm. Preliminary clinical results from patients included in this study indicate that TL was shorter in spermatozoa from couples who never achieved a pregnancy compared to couples who did achieve at least one natural pregnancy (p < .05); however, the clinical utility of this biomarker still needs to be confirmed in further studies.

ABSTRACT

OBJECTIVES: To compare, via CT imaging, the spread of different volumes of diluted iodinated contrast medium in the transversus abdominis muscle plane of dog cadavers. METHODS: Prospective, randomised study. An electro stimulation or a SonoTAP needle was inserted in plane with the ultrasound beam in the fascia between the internal oblique and transversus abdominis muscles. A test dose of 1 ml of diluted contrast (30 mg/mL iohexol) was injected to confirm positioning, followed by 0 · 5 mL/kg (n=14) or 1 mL/kg (n=12) and the distribution of the fluid compared. RESULTS: Contrast medium was identified exclusively in the transversus abdominis plane in 19 of 26 dogs. In one dog, the contrast lay between the external and internal oblique muscles and partially in three dogs. Intraperitoneal contrast was detected in 6 of 26 dogs (23%). No significant differences were found in the dorso-ventral or cranio-caudal spread or area of distribution but a significant difference was found in the transverse spread. There was an association between poor ultrasound visualisation of the tip of the needle and intraperitoneal injection. CLINICAL SIGNIFICANCE: Injection of 1 mL/kg of diluted contrast did not result in wider cranio-caudal spread in the transversus abdominis muscle plane of dog cadavers when compared with 0 · 5 mL/kg. Intraperitoneal injection is a risk and might be reduced with good needle visualisation.

ABSTRACT

There is an interest in the nuclear degraded sperm subpopulation because, although it is present in a low percentage in all semen samples, patient groups such as varicocele and rearranged genome carriers show high levels of these degraded spermatozoa. This study is designed with two objectives in mind: first, incubations of H2 O2 and nuclease on DTT-treated and untreated samples to show the aetiology of this subpopulation and second, assessment of the correlation between the protamine ratio and nuclear degraded spermatozoa. A very high increase in the nuclear degraded subpopulation has been found with nuclease incubation, and it is even higher when it has been merged with nuclear decompaction using DTT. Alternatively, incubation with H2 O2 with and without DTT did not show such a significant increase in nuclear degraded spermatozoa. The protamine ratio correlated with this subpopulation, showing, in patients, that poor nuclear compaction would turn the sperm susceptible to degradation. Then, the assessment of nuclear degraded spermatozoa might not be only a measure of DNA degradation but also an indicator of chromatin compaction in the spermatozoa. Different patient groups would fit this model for sperm nuclear degradation, such as varicocele patients, who show a high percentage of immature spermatozoa and nuclear degraded spermatozoa, and reorganised genome carriers, where reorganisation might also cause poor chromatin compaction on the sperm nucleus.

ABSTRACT

Sperm cryopreservation is widely used for both research and reproduction purposes, but its effect on sperm DNA damage remains controversial. Sperm DNA fragmentation (SDF) has become an important biomarker to assess male infertility. In particular, the differentiation between single- and double-stranded DNA fragmentation (ssSDF and dsSDF) has clinical implications for male infertility where ssSDF is associated with reduced fertility, whereas dsSDF is associated with increased risk of miscarriage. In this study, semen samples from 30 human males have been analysed in both fresh and cryopreserved using the alkaline and neutral Comet assays. Results show an increase of about 10% of ssSDF, assessed by the alkaline Comet assay, regardless of the male fertility status. Neutral Comet analysis of dsSDF does not show any statistical increase when comparing fresh and cryopreserved samples in any of the patient groups. Results support previous reports that oxidative stress is the major effector in DNA damage during sample cryopreservation, as, on one hand, ssSDF has previously been related to oxidative damage and, on the other hand, we have not found any effect on dsSDF. Therefore, there might be a slight risk of decreased fertility after using a freezed sample, but no evidence for increased miscarriage risk from cryopreserved spermatozoa should be expected.

ABSTRACT

Sperm DNA fragmentation (SDF) is becoming an important test to assess male infertility. Several different tests are available, but no consensus has yet been reached as to which tests are most predictive of infertility. Few publications have reported a comprehensive analysis comparing these methods within the same population. The objective of this study was to analyze the differences between the five most common methodologies, to study their correlations and to establish their cut-off values, sensitivity and specificity in predicting male infertility. We found differences in SDF between fertile donors and infertile patients in TUNEL, SCSA, SCD and alkaline Comet assays, but none with the neutral Comet assay. The alkaline COMET assay was the best in predicting male infertility followed by TUNEL, SCD and SCSA, whereas the neutral COMET assay had no predictive power. For our patient population, threshold values for infertility were 20.05% for TUNEL assay, 18.90% for SCSA, 22.75% for the SCD test, 45.37% for alkaline Comet and 34.37% for neutral Comet. This work establishes in a comprehensive study that the all techniques except neutral Comet are useful to distinguish fertile and infertile men.

ABSTRACT

Omalizumab is an effective drug for allergic asthma. The purpose of this study was to evaluate the effectiveness and tolerance of this drug in non-allergic GINA step V asthma patients. This study was single-centre, prospective, open-label, observational, naturalistic. Non-allergic asthma patients requiring a mean dose of oral prednisolone of at least 5 mg/day during greater than or equal to 1 year or an accumulated oral corticosteroid dose/year greater than or equal to 1500 mg were enrolled. At entry and the end of the 12-month follow-up we measured blood eosinophilia and IgE concentration; at every monthly visit a forced spirometry and exhaled fraction of nitric oxide (NO) were carried out. The subjects were seven adult patients (5 female), age range 37-63 years, with the following mean values: IgE: 226.7+/-176 IU/mL; FVC 74+/-18 percent; FEV1 57+/-11 percent; NO: 21.2+/-7 ppb. The study was approved by the IRB of the hospital. One patient decided to stop treatment after 12 weeks and was excluded from the evaluation. We did not observe changes in eosinophil count, spirometry or NO values. Three patients considered responders did not need prednisolone during the follow-up. The mean daily dose of prednisolone fell from 6.6+/-8.1 mg/day at entry to 1.5+/-2.3 mg/day (p less than 0.16) at the end of follow-up. The mean monthly accumulated dose fell from 92+/-112 to 12+/-26 mg/month (p=0.26). Total blood IgE increased 1.93-fold. Side effects were only local: treatment tolerance was excellent; three out of six patients seemed to slightly benefit from anti-IgE treatment; to date there is no evidence strong enough to systematically prescribe omalizumab in non-allergic asthma patients.

ABSTRACT

The primary aim of this study was to determine the effect of oral antioxidant treatment (1500 mg of l-Carnitine; 60 mg of vitamin C; 20 mg of coenzyme Q10; 10 mg of vitamin E; 10 mg of zinc; 200 µg of vitamin B9; 50 µg of selenium; 1 µg of vitamin B12) during a time period of 3 months upon the dynamics of sperm DNA fragmentation following varying periods of sperm storage (0 h, 2 h, 6 h, 8 h and 24 h) at 37 °C in a cohort of 20 infertile patients diagnosed with asthenoteratozoospermia. A secondary objective was to use the sperm chromatin dispersion test (SCD) to study antioxidant effects upon a specific subpopulation of highly DNA degraded sperm (DDS). Semen parameters and pregnancy rate (PR) were also determined. Results showed a significant improvement of DNA integrity at all incubation points (P < 0.01). The proportion of DDS was also significantly reduced (P < 0.05). Semen analysis data showed a significant increase in concentration, motility, vitality and morphology parameters. Our results suggest that antioxidant treatment improves sperm quality not only in terms of key seminal parameters and basal DNA damage, but also helps to maintain DNA integrity. Prior administration of antioxidants could therefore promote better outcomes following assisted reproductive techniques.

ABSTRACT

INTRODUCTION: According to Spanish health regulations, primary care professionals have the responsibility to carry out health-promoting community activities (CAs). However, in practice, their implementation is not as widespread as it should be. The aims of this study were to identify factors within the team, the community and the professionals that influence the development of these activities and to describe the community interventions in progress. METHODS AND ANALYSIS: This study is an observational analytical retrospective study. The information will be collected from five Spanish regions: Catalonia, Madrid, the Balearic Islands, Navarra and Aragón. The authors will contact primary care teams (PCTs) and identify the CAs from the previous year. The research team will conduct a peer review whether the inclusion criteria are met. In the health centres where CAs are implemented, the authors will select professionals carrying them out and randomly select an identical number of professionals not doing these activities. In the centres where no CA is implemented, three professionals will be randomly selected. The selected professionals will complete the questionnaires for individual-level variables. Information about the registered population and the PCTs will be collected through questionnaires and secondary sources. OUTCOMES: Variables will be collected from the community, the PCTs, the individual professionals and CAs. ANALYSIS: A descriptive analysis of all the variables will be carried out, along with a bivariate and a logistic regression analysis, with CAs being the primary outcome. ETHICS AND DISSEMINATION: This study has been approved by the Research Ethics Committee of the Jordi Gol y Gurina Foundation in Barcelona and area 11 in Madrid. The questionnaire distributed to the professionals will be anonymous.

ABSTRACT

BACKGROUND: The analysis of sperm DNA fragmentation has become a new marker to predict male infertility, and many techniques have been developed. The sperm Comet assay offers the possibility of differentiating single- and double-stranded DNA (ssDNA and dsDNA) breaks, which could have different effects on fertility. The objective of this study was to perform a descriptive characterization of different groups of patients, such as those with asthenoteratozoospermic (ATZ) with or without varicocele, oligoasthenoteratozoospermic (OATZ) or balanced chromosome rearrangements, as compared with fertile donors. The Comet assay was used to investigate sperm samples for ssDNA and dsDNA breaks. METHODS AND RESULTS: The analysis of alkaline and neutral Comet assays in different groups of patients showed different sperm DNA damage profiles. Most fertile donors presented low values for ssDNA and dsDNA fragmentation (low-equivalent Comet profile), which would be the best prognosis for achieving a pregnancy. OATZ, ATZ and ATZ with varicocele presented high percentages of ssDNA and dsDNA fragmentation (high-equivalent Comet assay profile), ATZ with varicocele being associated with the worst prognosis, due to higher levels of DNA fragmentation. Rearranged chromosome carriers display a very high variability and, interestingly, two different profiles were seen: a high-equivalent Comet assay profile, which could be compatible with a bad prognosis, and a non-equivalent Comet assay profile, which has also been found in three fertile donors. CONCLUSIONS: Comet assay profiles, applied to different clinical groups, may be useful for determining prognosis in cases of male infertility.

ABSTRACT

BACKGROUND: Quantification and description of patients recently infected by HIV can provide an accurate estimate of the dynamics of HIV transmission. Between 2006 and 2008 in Catalonia, we estimated the prevalence of recent HIV infection among newly diagnosed cases, described the epidemiological characteristics of the infection according to whether it was recent, long-standing or advanced, and identified factors associated with recent infection. METHODS: A Test for Recent Infection (TRI) was performed in serum samples from patients newly diagnosed with HIV. Two different TRI were used: the Vironostika-LS assay (January 2006-May 2007) and the BED-CEIA CEIA (June 2007 onwards). Samples were obtained within the first 6 months of diagnosis. Patients whose samples tested positive in the TRI were considered recently infected. RESULTS: Of 1125 newly diagnosed patients, 79.9% were men (median age, 35.4 years), 38.7% were born outside Spain, 48.9% were men who have sex with men (MSM) and 10.6% presented other sexually transmitted infections. The overall percentage of recent infection was 23.0%, which increased significantly, from 18.1% in 2006 to 26.2% in 2008. This percentage was higher for patients from South America (27.6%). Factors associated with recent infection were acquiring infection through sexual contact between MSM [odds ratio (OR) 2.0; 95% confidence interval (95% CI) 1.1-3.9], compared with acquiring infection through heterosexual relations and being under 30 years of age (OR 5.9; 95% CI 1.9-17.4), compared with being over 50 years of age. CONCLUSION: The highest percentage of recent infection was identified in MSM, suggesting either a higher incidence or a greater frequency of HIV testing. Information regarding testing patterns is necessary to correctly interpret data from recently infected individuals. Systems to monitor the HIV epidemic should include both parameters.

ABSTRACT

Los objetivos de este estudio fueron evaluar la prevalencia de las resistencias primarias transmitidas (RPT)y de subtipos de VIH-1 en pacientes recientemente infectados en Cataluña entre 2003 y 2005, y describirlas características de estos pacientes según la presencia o ausencia de RPT y el subtipo de VIH-1.Métodos: Después de la aplicación del algoritmo de pruebas serológicas para la seroconversión reciente al VIH (STARHS), alícuotas residuales de las muestras de suero de individuos recientemente infectados no tratados previamente con antirretrovirales fueron genotipados. Las secuencias FASTA se analizaron conel programa HIV db. Se utilizó el listado de mutaciones de la Organización Mundial de la Salud del 2009para estimar la prevalencia de resistencias transmitidas. Resultados: De 182 pacientes recientemente infectados, 14 (7,7%) presentaron RPT. Siete personas (3,8%)presentaban evidencias genotípica de RPT a los inhibidores de la transcriptasa inversa no análogos anucleósidos, 6 (3,3%) frente a inhibidores de la transcriptasa inversa análogos de nucleósidos, 3 (1,6%)frente a los inhibidores de la proteasa, y solo 2 personas (1,1%) presentaron RPT a más de una familia de medicamentos. Treinta y cinco (19,2%) pacientes estaban infectados con un subtipo no-B del VIH-1.Conclusión: Este es el primer estudio que estima la prevalencia de RPT en pacientes recientemente infectadosen Cataluña, y los resultados son similares a los de estudios realizados en otras regiones españolas. Para el adecuado seguimiento de estos parámetros es necesaria la vigilancia epidemiológica sistemática de las RPT (AU)


Objectives: The objectives of this study were to assess the prevalence of transmitted HIV-1 drug resistances(TDR) and HIV-1 subtypes in recently infected patients in Catalonia between 2003 and 2005 and to describe the characteristics of these patients according to the presence or absence of TDR and HIV-1subtype.Methods: After application of the Serological Testing Algorithm for Recent HIV Seroconversion (STARHS),residual aliquots of serum samples from recently infected antiretroviral-naïve individuals were genotyped. FASTA sequences were analyzed using the HIVDB Program. The World Health Organization 2009List of Mutations for Surveillance of Transmitted HIV-1 Drug Resistant HIV Strains was used to estimate the prevalence of TDR. Results: Of 182 recently infected patients, 14 (7.7%) presented TDR. Seven (3.8%) had genotypic evidence of TDR against non-nucleoside reverse transcriptase inhibitors, 6 (3.3%) against nucleoside reverse transcriptase inhibitors, 3 (1.6%) against protease inhibitors (PIs), and only 2 individuals (1.1%) presented TDR against more than one class of drugs. Thirty-five (19.2%) patients were infected with a non-B HIV-1subtype.Conclusion: This is the first study to estimate the prevalence of TDR in recently infected patients in Catalonia. The results are similar to those of studies performed in other Spanish regions. Correct monitoring of these parameters requires systematic epidemiologic surveillance of transmitted resistance (AU)

ABSTRACT

This investigation was conducted to assess the baseline level of sperm DNA fragmentation (SDF) in a cohort of patients presenting chromosomal rearrangements (nine reciprocal translocations and two inversions). In a separate experiment, a dynamic analysis to calculate the rate of SDF (rSDF), after a varying period of sperm storage (0 h, 1 h, 4 h, 8 h and 24 h) at 37 °C, was performed. Results were compared with eight fertile donors. Different experimental approaches to assess SDF, such as terminal transferase dUTP nick-end labelling (TUNEL), sperm chromatin structure assay (SCSA) and sperm chromatin dispersion test (SCDt), were used. No differences for the baseline level of SDF were found. Carriers of reorganized genomes showed statistically higher levels of SDF than did control donors (p = 0.025 for TUNEL; p = 0.022 for SCSA; p = 0.014 for SCDt). However, 54.5% (6/11) of the patients presented values similar to those of control donors. There was no significant difference in rSDF (p = 0.34). Nevertheless, the results suggest that a high variability for SDF and rSDF exists in these patients. Routine analysis of SDF and rSDF should be considered in patients presenting rearranged genomes to determine fertility status for assisted reproductive techniques (ART) purposes.

ABSTRACT

Although several reports on male infertility suggest a relationship between chromosome 9 polymorphisms and infertility, the effects on the phenotype have not been extensively reported. In this study, an infertile patient was found to carry a 9qh+++ chromosome. The flow cytometric TUNEL assay and SCD test have been applied to characterize sperm DNA integrity. In order to assess its meiotic behaviour, synapsis, recombination, and aneuploidy, analyses have been also performed. Sperm DNA fragmentation (SDF) was 77.81% and 87% for the TUNEL and SCD tests, respectively. Ninety-two percent of pachytene cells analyzed showed meiotic abnormalities. The mean number of MLH1 foci per pachytene in the control group was higher (49) than the mean found in the 9qh+++ patient (38) (P < .0001). In spermatozoa, significant increases of disomy rates were observed for chromosome 18 and for the sex chromosomes (P < .0001). These disturbances could be present in other male carriers of a less marked 9qh+.

ABSTRACT

ObjetivoEs describir los cambios producidos, por la Ley del tabaco en su consurno, en fumadores trabajadores activos.DiseñoEstudio de seguimiento, post-intevención, de una cohorte de usuarios.EmplazamientoCentros de salud de Valencia y Mallorca.ParticipantesUsuarios que acuden a los centros de salud.IntervencionesEl trabajo de campo consistió en la captación y cumplirnentación, para cada paciente, de una hoja de recogida de datos.Mediciones principalesLas variables que se recogieron fueron sexo, edad, lugar de trabajo, nivel educativo, número de trabajadores de la empresa, número de cigarrillos fumados. Se le indicó, que al día siguiente contara los cigarrillos fumados durante todo el día, diferenciando si había sido en horario laboral o fuera de él. Si fue en el trabajo informó si había sido dentro del lugar de trabajo o fuera. Al día siguiente se le llamó por teléfono para que nos indicara el número de cigarrillos fumados. Se repitió esta llamada a los seis y dieciocho meses.ResultadosSe ha reducido la prevalencia en un 9% al mes, y el número de cigarrillos fumados en el lugar de trabajo. Las variables relacionadas con cumplir la ley fueron el nivel educativo, el sexo del trabajador y el tamaño de la empresa.ConclusionesLa entrada en vigor de la Ley del tabaco ha sido efectiva(AU)

ABSTRACT

OBJECTIVE: The aim of this study is to describe the changes caused by the Law on Tobacco and its consumption in workers who are active smokers. DESIGN: A post-intervention follow up study of a cohort of users. SETTING: Health Centres in Valencia and Majorca. PARTICIPANTS: Users who attended health centres. INTERVENTION: The field work consisted of each patient filling in a case report form with the requested information. MAIN MEASUREMENTS: The variables collected were, sex, place of work, education level, number of workers in the company, number of cigarettes smoked. They were told that on the following day they had to count the cigarettes smoked throughout the day, noting whether they had been smoked during or outside working hours. If they smoked during working hours, they reported whether it was inside or outside the workplace. On the following day they were telephoned to let us know the number of cigarettes smoked. This telephone call was repeated at six months and eighteen months. RESULTS: Smoking prevalence and the number of cigarettes smoked in the workplace has been reduced by 9% per month. The variables associated with compliance with the law were education level, the sex of the worker, and the size of the company. CONCLUSIONS: The coming into force of the Tobacco Law has been effective.
