Serum microRNAs Catalog Asthma Patients by Phenotype.

BACKGROUND AND OBJECTIVES: Asthma is a chronic inflammatory condition of the airways with a complex pathophysiology. Stratification of asthma subtypes into phenotypes and endotypes should move the field forward, making treatment more effective and personalized. Eosinophils are the key inflammatory cells involved in severe eosinophilic asthma. Given the health threat posed by eosinophilic asthma, there is a need for reliable biomarkers to identify affected patients and treat them properly with novel biologics. microRNAs (miRNAs) are a promising diagnostic tool. The aim of this study was to identify serum miRNAs that can phenotype asthma patients. METHODS: Serum miRNAs of patients with eosinophilic asthma (N=40) and patients with noneosinophilic asthma (N=36) were evaluated using next-generation sequencing, specifically miRNAs-seq, and selected miRNAs were validated using RT-qPCR. Pathway enrichment analysis of deregulated miRNAs was performed. RESULTS: Next-generation sequencing revealed 15 miRNAs that were expressed differentially between eosinophilic and noneosinophilic asthma patients, although no differences were observed in the miRNome between atopic and nonatopic asthma patients. Of the 15 miRNAs expressed differentially between eosinophilic and noneosinophilic asthma patients, hsa-miR-26a-1-3p and hsa-miR-376a-3p were validated by RT-qPCR. Expression levels of these 2 miRNAs were higher in eosinophilic than in noneosinophilic asthma patients. Furthermore, expression values of hsa-miR-26a-1-3p correlated inversely with peripheral blood eosinophil count, and hsa-miR-376a-3p expression values correlated with FeNO values and the number of exacerbations. Additionally, in silico pathway enrichment analysis revealed that these 2 miRNAs regulate signaling pathways associated with the pathogenesis of asthma. CONCLUSIONS: hsa-miR-26a-1-3p and hsa-miR-376a-3p could be used to differentiate between eosinophilic and noneosinophilic asthma.

The incorporation of HIV self-testing as an exclusive option among men who have sex with men in Spain: results of an online cross-sectional study.

BACKGROUND: We assessed to what extent HIV self-testing would be incorporated by men who have sex with men (MSM) with previous testing history as their exclusive testing option and describe what actions they would take in the case of obtaining a reactive self-test. METHODS: We conducted an online survey among Spanish resident MSM recruited mainly in gay dating apps and analyze 6171 ever tested individuals. We used Poisson regression to estimate factors associated with the incorporation of self-testing as the exclusive testing option. Among those who would incorporate self-testing as their exclusive option, we described actions taken if obtaining a reactive self-test by number of tests in the past. RESULTS: Nearly half of the participants (48.3%) were > =35 years old, 84.6% were born in Spain, 57.9% had attained a university degree, 55.1% lived in a municipality of ≤500.000 and 86.4% self-identified as homosexual. For 37.2%, self-testing would become their exclusive testing option. The incorporation of self-testing as the exclusive option increased with age 25-34 (PR:1.1, 95%CI:1.0-1.3), 35-44 (PR:1.3, 95%CI:1.2-1.5), 45-49 (PR:1.5, 95%CI:1.3-1.7) and > 50 (PR:1.5, 95%CI:1.3-1.8) and in those who reported unprotected anal intercourse (PR:1.1, 95%CI:1.0-1.2) or having paid for sex (PR:1.2, 95%CI:1.0-1.3) in the last 12 months. It was also associated with having had < 10 HIV test in the past (2-9 tests (PR:1.3, 95%CI:1.1-1.4); 1 test (PR:1.5, 95%CI:1.3-1.7)), and having been tested ≥2 years (PR:1.4, 95%CI:1.3-1.5) or between 1 and 2 years ago (PR:1.1, 95%CI:1.0-1.2). Of participants who would use self-testing exclusively 76.6% would confirm their result in case of obtaining a reactive self-test and only 6.1% wouldn't know how to react. Only one individual expressed that he would do nothing at all. CONCLUSION: HIV self-testing could become the exclusive testing option for more than a third of our participants. It was chosen as the exclusive option especially by older, at risk and under-tested MSM. Self-testing strategies need to especially consider the linkage to care process. In this sense, only a small fraction would not know how to react and virtually nobody reported taking no action if obtaining a reactive result.

Social cognition in bipolar disorder: the role of sociodemographic, clinical, and neurocognitive variables in emotional intelligence.

OBJECTIVE: The main aims of this study were to examine the differences in the Emotional Intelligence (EI), the emotional domain of social cognition (SC), between euthymic patients with bipolar disorder (BD) and healthy controls (HC) and to evaluate the contribution of sociodemographic, clinical, and neuropsychological variables to EI. METHODS: We recruited 202 patients with BD and 50 HC. EI was evaluated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). The sociodemographic, clinical, and neurocognitive variables that showed a significant association with EI were entered into hierarchical multiple regression analysis. RESULTS: BD patients obtained significantly lower scores compared to HC in the Emotional Intelligence Quotient (EIQ) and in the Understanding Emotions branch score. The best fitting model for the variables associated with EI in the patients group was a linear combination of gender, estimated IQ, family history of affective diagnosis, and executive function. The model, including these previous variables, explained up to 27.6% of the observed variance (R2  = 0.276, F = 16.406, P < 0.001). CONCLUSIONS: The identification of variables associated with deficit in EI, such as male gender, lower estimated IQ, family history of affective diagnosis. and lower executive function performance, may help in selecting treatment targets to improve SC, and especially EI, in patients with BD.

Addressing the New Global Threat of Xylella fastidiosa.

Xylella fastidiosa is one of the most important threats to plant health worldwide. This bacterial pathogen has a long history, causing disease in the Americas on a range of agricultural crops and trees, with severe economic repercussions particularly on grapevine and citrus. In Europe, X. fastidiosa was detected for the first time in 2013 in association with a severe disease affecting olive trees in southern Italy. Subsequent mandatory surveys throughout Europe led to discoveries in France and Spain in various host species and environments. Detection of additional introductions of X. fastidiosa continue to be reported from Europe, for example from northern Italy in late 2018. These events are leading to a sea change in research, monitoring and management efforts as exemplified by the articles in this Focus Issue . X. fastidiosa is part of complex pathosystems together with hosts and vectors. Although certain X. fastidiosa subspecies and environments have been well studied, particularly those that pertain to established disease in North and South America, this represents only a fraction of the existing genetic, epidemiological, and ecological diversity. This Focus Issue highlights some of the key challenges that must be overcome to address this new global threat, recent advances in understanding the pathosystem, and steps toward improved disease control. It brings together the broad research themes needed to address the global threat of X. fastidiosa, encompassing topics from host susceptibility and resistance, genome sequencing, detection methods, transmission by vectors, epidemiological drivers, chemical and biological control, to public databases and social sciences. Open communication and collaboration among scientists, stakeholders, and the general public from different parts of the world will pave the path to novel ideas to understand and combat this pathogen.

Knowledge, actual and potential use of HIV self-sampling testing kits among MSM recruited in eight European countries.

AIM: To describe the knowledge as well as current and potential use of self-sampling kits among men who have sex with men (MSM) and to analyse their preferred biological sample and result communication method. METHODS: We analyse data of MSM of HIV negative or unknown serostatus from an online survey conducted in eight countries (Belgium, Denmark, Germany, Greece, Portugal, Romania, Slovenia and Spain) between April and December 2016. It was advertised mainly in gay dating websites. We conduct a descriptive analysis of the main characteristics of the participants, and present data on indicators of knowledge, use and potential use of HIV self-sampling as well as their preferences regarding blood or saliva sample and face or non-face-to-face result communication by country of residence. RESULTS: A total of 8.226 participants of HIV negative or unknown serostatus were included in the analysis. Overall, 25.5% of participants knew about self-sampling (range: 18.8-47.2%) and 1.1% had used it in the past (range: 0.3-8.9%). Potential use was high, with 66.6% of all participants reporting that they would have already used it if available in the past (range: 62.1-82.1%). Most (78.6%) reported that they would prefer using a blood-based kit, and receiving the result of the test through a non-face-to-face-method (70.8%), even in the case of receiving a reactive result. CONCLUSION: The high potential use reported by MSM recruited in eight different European countries suggests that self-sampling kits are a highly acceptable testing methodology that could contribute to the promotion of HIV testing in this population.

Early adipose deposits in sheep: comparative analysis of the perirenal fat transcriptome of Assaf and Churra suckling lambs.

Adipose deposits influence the quality of ruminant carcasses, and in suckling lambs, internal types of adipose deposits represent a notable proportion of total fat. The aim of this study was to perform a comparative analysis of the perirenal fat transcriptomes of suckling lambs from two breeds with different growth and carcass characteristics. The perirenal fat tissue from 14 suckling lambs (Assaf, n = 8; Churra, n = 6) was used for the RNA-seq analysis. The functional enrichment analysis of the 670 highly expressed genes (>150 fragments per kilobase of exon per million fragments mapped) in the perirenal fat transcriptome of both breeds revealed that the majority of these genes were involved in energy processes. The expression of the UCP1 gene, a classical biomarker of brown fat, and the presence of multilocular adipocytes in the two breeds supported the presence of brown fat at the transition stage towards white fat tissue. The differential expression analysis performed identified 373 differentially expressed genes (DEGs) between the two compared breeds. Brown/white fat gene biomarkers were not included in the list of DEGs. In Assaf lambs, DEGs were enriched in Gene Ontology (GO) biological processes related to fatty-acid oxidation, whereas in Churra lambs, the majority of the significantly enriched GO terms were related to cholesterol synthesis, which suggests that upregulated DEGs in Assaf lambs are implicated in fat burning, whereas the Churra upregulated DEGs are linked to fat accumulation. These results can help to increase knowledge of the genes controlling early fat deposition in ruminants and shed light on fundamental aspects of adipose tissue growth.

[Laparoscopic repair of inguinal hernia and communicating hydrocele in children. Our experience in the last years]. / Reparación laparoscópica de la hernia inguinal e hidrocele en edad pediátrica. Nuestra experiencia en los últimos años.

INTRODUCTION: Laparoscopic inguinal hernia and hydrocele repair has become an alternative to the more frequently used inguinal approach. We describe our experience with the laparoscopic technique. MATERIAL AND METHODS: Retrospective study of laparoscopic inguinal hernia and hydrocele repair performed during the period between 2003-2016. We included patients < 14 years, with communicating hydrocele and/or indirect inguinal hernia diagnosis (N = 39). We have studied two cohorts; group A patients with indirect inguinal hernia (N = 31) and group B patients with communicating hydrocele (N = 8). We used intraperitoneal laparoscopic approach, performing herniorrhaphy of the internal inguinal orifice without resection of the hernial sac. The main outcome measurements were surgical indication and postoperative complications. RESULTS: The indication for laparoscopic repair was bilateral defects (46.2%), unilateral defects (28.2%), defects associated with umbilical hernia (23.1%) and associated with another pathology (2.6%). In group A the rate of complications that required new admission was 3.2% and the recurrence rate was 9.7%. In group B, was 12.5% ​​and 12.5% respectively. We have not observed a significant relationship with respect to patient age, laterality or suture used and the rate of complications in any of the groups. CONCLUSIONS: Despite the limitations of our study given the small sample size and retrospective nature, the complication rate (15%) is higher than that published in the literature. This makes us take a step back to reassess our indications and technique, and not forget that the laparoscopic approach is not a technique without risks and requires a learning curve.

OBJETIVOS: La reparación laparoscópica de la hernia inguinal e hidroceles en la edad pediátrica, se ha convertido en una alternativa a la herniorrafia inguinal clásica. Describimos nuestra experiencia en las intervenciones realizadas con dicha técnica. MATERIAL Y METODOS: Estudio retrospectivo de las reparaciones laparoscópicas de hernia inguinal e hidrocele realizadas en el periodo 2003-2016. Se han incluido pacientes <14 años, diagnosticados de hidrocele comunicante y/o de hernia inguinal indirecta (N=39), divididos en dos cohortes: grupo A pacientes con hernia inguinal indirecta y grupo B pacientes con hidrocele comunicante. Se ha empleado el abordaje laparoscópico intraperitoneal, y anillorrafia del orificio inguinal interno sin resección del saco herniario. Las variables principales estudiadas han sido la indicación quirúrgica y las complicaciones postquirúrgicas. RESULTADOS: Las indicaciones quirúrgicas han sido los defectos bilaterales (46,2%), defectos unilaterales (28,2%), defectos asociados a hernia umbilical (23,1%) y asociados a otra patología (2,6%). En el grupo A la tasa de complicaciones que precisaron de ingreso fue de 3,2% y la tasa de recurrencias fue de 9,7%; mientras que en el B han sido del 12,5% y del 12,5% respectivamente. No hay una relación significativa respecto a la edad, la lateralidad o la sutura utilizada y la tasa de complicaciones en ninguno de los grupos. CONCLUSIONES: A pesar de las limitaciones del estudio, el porcentaje total de complicaciones (15,3%) es más elevado que el publicado en la literatura. Esto nos hace reflexionar y no olvidar que el abordaje laparoscópico no es una técnica exenta de riesgos y requiere de una curva de aprendizaje.

[Onychomadesis secondary to hand-foot-mouth disease: a frequent manifestation and cause of concern for parents]. / Onicomadesis secundaria a enfermedad pie-mano-boca: una manifestación frecuente y motivo de preocupación de los padres.

INTRODUCTION: Nail alterations in children are an important cause of parent anxiety and derive in multiple and unnecessary consultations. The onychomadesis corresponds to the complete and pain less detachment of the nail plate from the proximal fold. This self-resolving nail finding has been described as a late complication of hand-foot-mouth disease, a frequent viral exanthema in the pedia tric age. OBJECTIVE: To describe a classic pediatric case of hand-foot-mouth disease with subsequent onychomadesis. CLINICAL CASE: A 3-years-old male patient with an acute presentation of acute erythe matous perioral papulovesicles, which extend to upper extremities and hands, buttocks, thighs and feet, asymptomatic, and without compromising general condition. Skin lesions resolve completely, but after one month, he develops detachment of the nails, with subsequent complete recovery. Con clusions: The recognition of this association will allow primary care physicians to guide the parents about a benign and self-resolving process that may occur as part of the evolution of hand-foot-mouth disease, thus avoiding unnecessary anxiety, referral and treatments.

Tinea nigra: Report of three pediatrics cases. / Tiña negra: reporte de tres casos pediátricos.

INTRODUCTION: Tinea nigra is a superficial mycosis caused by Hortaea werneckii. Its clinical characte ristic is the appearance of a blackish brown macula of rapid growth, caused by the pigment produced by the fungus itself. The presence of a dark, fast growing, acral pigmentary lesion causes concern among patients and their treating physician about the possibility of a malignant pigmentary lesion. OBJECTIVE: To present a series of three clinical cases in pediatric patients with this pathology and to show the tools that help to make a differential diagnosis. CLINICAL CASES: Three patients between three and five years of age, which present a macular pigmented lesion on palms or soles, whose parents reported a rapid growth over a short period of time. Two of the patients reported previous trips to the Caribbean. Clinical and dermatoscopy suspicion of tinea nigra lead to a direct mycological exa mination, which confirmed the diagnosis. In all three cases, treatment with topical antifungals led to complete healing of the lesions. CONCLUSIONS: Although tinea nigra is rare in a dry climate, increasing travel of patients to tropical countries will increase the number of cases. Dermatoscopy and direct mycological examination are the tools that allow performing a correct diagnosis and avoiding unne cessary biopsies and/or surgeries.

Cancer Incidence in Heart Transplant Recipients With Previous Neoplasia History.

Neoplasm history increases morbidity and mortality after solid organ transplantation and has disqualified patients from transplantation. Studies are needed to identify factors to be considered when deciding on the suitability of a patient with previous tumor for heart transplantation. A retrospective epidemiological study was conducted in heart transplant (HT) recipients (Spanish Post-Heart Transplant Tumor Registry) comparing the epidemiological data, immu-nosuppressive treatments and incidence of post-HT tumors between patients with previous malignant noncardiac tumor and with no previous tumor (NPT). The impact of previous tumor (PT) on overall survival (OS) was also assessed. A total of 4561 patients, 77 PT and 4484 NPT, were evaluated. The NPT group had a higher proportion of men than the PT group (p < 0.001). The incidence of post-HT tumors was 1.8 times greater in the PT group (95% confidence interval [CI] 1.2-2.6; p < 0.001), mainly due to the increased risk in patients with a previous hematologic tumor (rate ratio 2.3, 95% CI 1.3-4.0, p < 0.004). OS during the 10-year posttransplant period was significantly lower in the PT than the NPT group (p = 0.048) but similar when the analysis was conducted after a first post-HT tumor was diagnosed. In conclusion, a history of PT increases the incidence of post-HT tumors and should be taken into account when considering a patient for HT.

The rapid test in Spanish pharmacies: a novel programme to reach heterosexual men?

OBJECTIVES: Spain has been a pioneer in the implementation of rapid HIV testing programmes in pharmacies to increase access to testing. However, no formal evaluation of the effectiveness of these programmes has been carried out to date. Our aim was to evaluate the ability of a novel in-pharmacy rapid HIV testing programme to promote diagnosis and reach vulnerable populations. METHODS: Between 2011 and 2012, 2168 people underwent testing in 16 urban pharmacies in 10 cities of a Spanish region with a low prevalence of HIV infection. The main outcomes of the programme were compared with those of the regional surveillance system for new HIV diagnoses (RHSS-CyL). RESULTS: Overall, 52.8% of those tested were heterosexual men, 15.8% were men who have sex with men (MSM) and 25.3% were women. Nine per cent were immigrants and 41.9% were < 30 years old. In total, 59.5% of the heterosexual men, 44.6% of the MSM and 65.3% of the women were previously untested. There were 23 positive results, representing 6% of all new regional diagnoses in 2011. The global prevalence was 1.1% (95% confidence interval 0.6-1.5%) and the prevalence in MSM was 3.8%. Of the reactive results, 60.9% were in MSM, 34.8% in heterosexual men and only 4.3% in women, vs. 35.4%, 37.5% and 15.0%, respectively, reported by the RHSS-CyL. The mean age of those testing positive was 32.7 years vs. 38.7 years in the RHSS-CyL. Fifty per cent of MSM and 75% of heterosexual men testing positive were previously untested. CONCLUSIONS: In Spain, this is the first programme not targeted at the most at-risk populations, and has been shown to be effective in reaching and diagnosing heterosexual men, who are the group most affected by delayed diagnoses. Heterosexual men accounted for over half of those tested and a third of those diagnosed, and most of them were previously untested. Young and previously untested MSM also greatly benefitted from the programme.

Xylella fastidiosa Isolates from Both subsp. multiplex and fastidiosa Cause Disease on Southern Highbush Blueberry (Vaccinium sp.) Under Greenhouse Conditions.

Xylella fastidiosa is a xylem-limited gram-negative plant pathogen that affects numerous crop species, including grape, citrus, peach, pecan, and almond. Recently, X. fastidiosa has also been found to be the cause of bacterial leaf scorch on blueberry in the southeastern United States. Thus far, all X. fastidiosa isolates obtained from infected blueberry have been classified as X. fastidiosa subsp. multiplex; however, X. fastidiosa subsp. fastidiosa isolates are also present in the southeastern United States and commonly cause Pierce's disease of grapevines. In this study, seven southeastern U.S. isolates of X. fastidiosa, including three X. fastidiosa subsp. fastidiosa isolates from grape, one X. fastidiosa subsp. fastidiosa isolate from elderberry, and three X. fastidiosa subsp. multiplex isolates from blueberry, were used to infect the southern highbush blueberry 'Rebel'. Following inoculation, all isolates colonized blueberry, and isolates from both X. fastidiosa subsp. multiplex and X. fastidiosa subsp. fastidiosa caused symptoms, including characteristic stem yellowing and leaf scorch symptoms as well as dieback of the stem tips. Two X. fastidiosa subsp. multiplex isolates from blueberry caused more severe symptoms than the other isolates examined, and infection with these two isolates also had a significant impact on host mineral nutrient content in sap and leaves. These findings have potential implications for understanding X. fastidiosa host adaptation and expansion and the development of emerging diseases caused by this bacterium.

Assessment of an outreach street-based HIV rapid testing programme as a strategy to promote early diagnosis: a comparison with two surveillance systems in Spain, 2008-2011.

We assess the added value of a multisite, street-based HIV rapid testing programme by comparing its results to pre-existing services and assessing its potential to reduce ongoing transmission. Between 2008 and 2011, 8,923 individuals underwent testing. We compare outcomes with those of a network of 20 sexually transmitted infections (STI)/HIV clinics (EPI-VIH) and the Spanish National HIV Surveillance System (SNHSS); evaluate whether good visibility prompts testing and assess whether it reaches under-tested populations. 89.2% of the new infections were in men who have sex with men (MSM) vs 78.0% in EPI-VIH and 56.0% in SNHSS. 83.6% of the MSM were linked to care and 20.9% had <350 CD4 HIV prevalence was substantially lower than in EPI-VIH. 56.5% of the HIV-positive MSM tested because they happened to see the programme, 18.4% were previously untested and 26.3% had their last test ≥2 years ago. The programme provided linkage to care and early diagnosis mainly to MSM but attendees presented a lower HIV prevalence than EPI-VIH. From a cost perspective it would benefit from being implemented in locations highly frequented by MSM. Conversely, its good visibility led to reduced periods of undiagnosed infection in a high proportion of MSM who were not testing with the recommended frequency.

Ionome changes in Xylella fastidiosa-infected Nicotiana tabacum correlate with virulence and discriminate between subspecies of bacterial isolates.

Characterization of ionomes has been used to uncover the basis of nutrient utilization and environmental adaptation of plants. Here, ionomic profiles were used to understand the phenotypic response of a plant to infection by genetically diverse isolates of Xylella fastidiosa, a gram-negative, xylem-limited bacterial plant pathogen. In this study, X. fastidiosa isolates were used to infect a common model host (Nicotiana tabacum 'SR1'), and leaf and sap concentrations of eleven elements together with plant colonization and symptoms were assessed. Multivariate statistical analysis revealed that changes in the ionome were significantly correlated with symptom severity and bacterial populations in host petioles. Moreover, plant ionome modification by infection could be used to differentiate the X. fastidiosa subspecies with which the plant was infected. This report establishes host ionome modification as a phenotypic response to infection.

Persistent pulmonary abnormalities after 18 months of SARS-CoV-2 pneumonia.

OBJECTIVE: To describe persistent pulmonary abnormalities detected on HRCT after 18 months of SARS-CoV-2 pneumonia, and to determine their extension and correlation with pulmonary function. PATIENTS AND METHODS: A prospective cross-sectional study with an initial cohort of 90 patients in follow-up due to persisting lung abnormalities on imaging, functional respiratory impairment and/or respiratory symptoms. Of these, 31 (34%) were selected for analysis due to the persistence of their lung abnormalities on HRCT at 18 months after infection. A double reading was performed for each HRCT (62 observations). RESULTS: Of the 31 patients included: 20 (65%) were men; mean age was 67 years; 17 (55%) were smokers/ex-smokers. The mean hospitalisation time was 38 days. Eighteen (58%) patients were admitted to intensive care units. Five patients (16%) suffered an acute pulmonary thromboembolism and three (9.7%) had a pneumothorax. The mean time between the onset of pneumonia and the follow-up HRCT was 20.34 months. Nineteen percent of patients suffered from total lung function abnormalities; and ground-glass opacities and reticulation were present in 12% and 4.5% respectively. The findings of the 62 readings were: ground-glass opacities (100%), reticulation (83%), subpleural curvilinear lines (62%), parenchymal bands (34%), traction bronchiectasis (69%), displacement of vessels/fissures (46%) and honeycombing (4.9%). Pulmonary function 18 months after the acute episode revealed a mean FVC of 92% of predicted value, with an FVC < 80% of predicted value in 11 patients (35.4%). Mean DLCO was 71% of predicted value, with a DLCO < 80% in 22 patients (70%). We observed a statistically significant relationship between total lung function abnormalities on HRCT and FVC (P < 0.05), and a trend towards statistical significance with DLCO (P = 0.051); there was a statistically significant relationship between the presence of ground-glass opacities and FEV1/FVC (P < 0.01). The relationships between reticulation and FVC, FVC%, FEV1, FEV1% and DLCO% were also considered statistically significant (P < 0.05). CONCLUSION: Persistent interstitial lung abnormalities are seen on HRCT for a subset of patients infected with SARS-CoV-2 pneumonia. Seventy percent of these patients suffered a slight decrease in DLCO.

Characterization and treatment of enuresis in overactive bladder patients. / Caracterización y tratamiento de la enuresis en pacientes con vejiga hiperactiva.

OBJECTIVE: To define the types of overactive bladder (OAB) patient enuresis and study daytime bladder treatment response. MATERIALS AND METHODS: A prospective, multi-center study of OAB patients with enuresis treated with anticholinergics or neuromodulation over 3 months from 2019 to 2021 was carried out. Variables achieved from the voiding calendar and PLUTSS (Pediatric Lower Urinary Tract Score System), as well as enuresis-related variables, were collected. Two study groups were created -primary enuresis (PE) and secondary enuresis (SE). Partial enuretic response (PER) was defined as a > 50% reduction in baseline enuresis, and complete enuretic response (CER) as a 100% reduction. A multivariate analysis was eventually conducted to detect CER independent predictive factors. RESULTS: 152 OAB patients were included. 109 of them (71.7%) had enuresis -29 (26.7%) SE and 80 (73.3%) PE. PLUTSS score was higher in PE patients than in SE patients (20.8 vs. 17.2; p= 0.001). PER and CER were significantly higher in the SE group (55.2% vs. 15%; p= 0.000 in PER, and 48.3% vs. 5%; p= 0.000 in CER). In the multivariate analysis, SE patients demonstrated to have a 50-fold increased probability of responding to daytime bladder treatment than PE patients (OR: 49.79; 95%CI: 6.73-36.8). CONCLUSIONS: Most OAB children have PE and not SE, which explains why enuresis does not typically respond to daytime bladder treatment. Characterizing the type of enuresis in OAB children is important to adequately approach treatment.

OBJETIVOS: Definir los tipos de enuresis de los pacientes con vejiga hiperactiva (VH) y estudiar su respuesta al tratamiento vesical diurno. MATERIAL Y METODOS: Estudio prospectivo y multicéntrico: pacientes con VH y enuresis, tratados con anticolinérgicos o neuromodulación durante 3 meses (2019-2021). Recogimos variables obtenidas del calendario miccional, cuestionario PLUTSS (Pediatric Lower Urinary Tract Score System), y relacionadas con la enuresis. Generamos 2 grupos de estudio: enuresis primaria (EP) y enuresis secundaria (ES). Consideramos respuesta parcial enurética (RPE) a la reducción del valor de enuresis inicial en más de un 50% y respuesta completa (RCE) el 100%. Finalmente realizamos un análisis multivariante para detectar factores predictivos independientes de RCE. RESULTADOS: Incluimos 152 pacientes con VH, 109 de los cuales presentaban enuresis (71,7%): 29 ES (26,7%) y 80 EP (73,3%). El valor PLUTSS fue mayor en pacientes con EP que en ES (20,8 vs. 17,2, p= 0,001.) La RPE y la RCE fueron significativamente mayores en el grupo de ES (55,2% vs. 15%, p= 0,000 en RPE y 48,3% vs. 5%, p= 0,000 en RCE). En el análisis multivariante se identificó que los pacientes con ES tienen una probabilidad de responder al tratamiento vesical diurno 50 veces superior que los pacientes con EP (OR 49,79, IC95% 6,73-36,8). CONCLUSIONES: La mayoría de niños con VH tienen una EP y no secundaria, por lo que generalmente la enuresis de estos pacientes no responde al tratamiento vesical diurno. Es importante caracterizar el tipo de enuresis de los niños con VH para plantear su tratamiento de forma adecuada.

Awareness and use of nonoccupational HIV post-exposure prophylaxis among people receiving rapid HIV testing in Spain.

OBJECTIVES: This paper examines the awareness and use of nonoccupational HIV post-exposure prophylaxis (nPEP) in Spain, and the factors that influence this awareness. METHODS: Between June 2009 and July 2010, a mobile unit offered free, rapid HIV tests in a number of Spanish cities. A total of 2545 people were passively recruited and tested, and answered a self-administered questionnaire containing sociodemographic, behavioural and nPEP-related questions. Bivariate and multivariate analyses were performed, stratifying by gender/sexual behaviour. RESULTS: Some 34% of the responders were men who have sex with men (MSM), 30% were men who have sex exclusively with women (MSW), and 35% were women. Approximately 26% were foreigners, 46% had a university degree, and 51% had previously taken an HIV test. Overall, 22% were aware of nPEP. Only 2% had ever used it; 70% of these after high-risk sexual intercourse. Awareness was higher among MSM (34%) than women (16%) and MSW (15%). Multivariate analysis showed a lack of nPEP awareness to be associated with being born in Latin America, while awareness increased with the number of previous HIV tests among women and MSW. In MSM, awareness was also associated with having a university degree, the degree of interaction with gay culture, number of partners, and use of the internet as the main way of meeting partners. CONCLUSIONS: nPEP awareness in the studied population was unacceptably low. The promotion of its availability should be made a major objective of prevention programmes, as a complementary measure to condom use.

Relationship among specific bacterial counts and total bacterial and somatic cell counts and factors influencing their variation in ovine bulk tank milk.

To analyze the relationship among the counts of different organisms and total bacterial count (BTTBC) and somatic cell count (BTSCC) as determined in dairy laboratories in ovine bulk tank milk, 751 bulk tank milk samples from 205 dairy sheep flocks belonging to Consortium for Ovine Promotion (CPO) were collected between January and December 2011. Four samplings were carried out in each flock, once per season, throughout 1 yr. Variables analyzed were bulk tank counts of thermoduric, psychrotrophic, coliform, and gram-positive catalase-negative cocci (GPCNC) bacterial groups. Thermoduric, psychrotrophic, and coliform species were significantly related to BTTBC, whereas GPCNC were correlated with both BTTBC and BTSCC variables. Highest counts were for psychrotroph and coliform groups, and a moderate to high correlation (r=0.51) was found between both variables, indicating that poor cleaning practices in the flocks tend to select for less-resistant organisms, such as gram-negative rods. In addition, BTTBC correlated with BTSCC (r=0.42). Some variation factors for specific bacterial counts, such as breed, season, milking type, dry therapy, and milk yield, were also analyzed. Flock information was collected from flock books, annual audits, and the CPO traceability system. Psychrotrophs and coliforms had elevated counts in winter, whereas GPCNC were higher in summer and in hand-milked flocks. Dry therapy contributed to the reduction in psychrotrophic bacteria; therefore, some strains of mammary pathogens could also be psychrotrophic bacteria. Results of this study would be helpful for troubleshooting milk quality problems and developing premium payment systems in dairy sheep.

Identification of quantitative trait loci underlying milk traits in Spanish dairy sheep using linkage plus combined linkage disequilibrium and linkage analysis approaches.

In this study, 2 procedures were used to analyze a data set from a whole-genome scan, one based on linkage analysis information and the other combing linkage disequilibrium and linkage analysis (LDLA), to determine the quantitative trait loci (QTL) influencing milk production traits in sheep. A total of 1,696 animals from 16 half-sib families were genotyped using the OvineSNP50 BeadChip (Illumina Inc., San Diego, CA) and analysis was performed using a daughter design. Moreover, the same data set has been previously investigated through a genome-wide association (GWA) analysis and a comparison of results from the 3 methods has been possible. The linkage analysis and LDLA methodologies yielded different results, although some significantly associated regions were common to both procedures. The linkage analysis detected 3 overlapping genome-wise significant QTL on sheep chromosome (OAR) 2 influencing milk yield, protein yield, and fat yield, whereas 34 genome-wise significant QTL regions were detected using the LDLA approach. The most significant QTL for protein and fat percentages was detected on OAR3, which was reported in a previous GWA analysis. Both the linkage analysis and LDLA identified many other chromosome-wise significant associations across different sheep autosomes. Additional analyses were performed on OAR2 and OAR3 to determine the possible causality of the most significant polymorphisms identified for these genetic effects by the previously reported GWA analysis. For OAR3, the analyses demonstrated additional genetic proof of the causality previously suggested by our group for a single nucleotide polymorphism located in the α-lactalbumin gene (LALBA). In summary, although the results shown here suggest that in commercial dairy populations, the LDLA method exhibits a higher efficiency to map QTL than the simple linkage analysis or linkage disequilibrium methods, we believe that comparing the 3 analysis methods is the best approach to obtain a global picture of all identifiable QTL segregating in the population at both family-based and population-based levels.
