RESUMEN
Patients with inflammatory bowel disease (IBD) treated with biologic and/or immunosuppressant drugs are at increased risk for opportunistic infections. Seroprevalence studies can confirm the diagnosis of SARS-CoV-2 infections as well as the associated risk factors. This is a descriptive study which primary endpoints were to highlight the prevalence of SARS-CoV-2 antibodies in a cohort of IBD patients in March 2021, and to analyze seroconversion in patients with known COVID-19 infection and its relationship with IBD treatments. Patients filled in a questionnaire about symptoms of COVID-19 infection and clinical information about their IBD. All included patients were tested for SARS-CoV-2 antibodies. 392 patients were included. Among patients with clinical infection, 69 patients (17,65%) were IgG-positive, 286 (73,15%) IgG-negative and 36 (9,21%) indeterminate. In relation to seroconversion among patients under biologic treatment, 13 patients of the 23 with a previous positive CRP developed antibodies (56.5%). However, when the influence of immunosuppressive treatment on the probability of developing antibodies was analyzed, no significant differences were seen between those patients with or without treatment (77.8% vs. 77.1%, p = 0.96). In our cohort of IBD patients, after one year of pandemic, there were 18.64% IgG positive patients, a higher prevalence than the general population (15.7%).

INTRODUCTION: In lung resection surgery, restrictive fluid therapy is recommended due to the risk of acute lung injury. In contrast, this recommendation increases the risk of hypoperfusion. Guided fluid therapy allows individualization of fluid intake. The use of dynamic volume response parameters is not validated during one-lung ventilation. The main objective is the validation of dynamic parameters, stroke volume variation (SVV) and pulse pressure variation (PPV), during lung resection surgery as fluid response predictors, after the administration of 250ml crystalloid volume loads, if IC<2.5ml/min/m2 and if SVV≥8% and/or PPV≥10%. MATERIAL AND METHODS: Pilot, prospective, observational and single centre study. Twenty-five patients monitored with the PiCCO system were included during open lung resection surgery with the patient in a lateral position, one lung ventilation with tidal volume (TV): 6ml/kg and open chest. Hemodynamic variables were collected before and after volume loading. The results were classified into two groups: volume responders (increase IC≥10% and/or VSI≥10% after volume loading) and non-responders (no increase or increase IC<10% and/or VSI<10% after volume loading). We assess the diagnostic efficacy of SVV and PPV by analyzing the AUC (area under curve) in the ROC curves. RESULTS: In the analysis of ROC curves, SVV and PPV did not reach a discriminative value (AUCSVV: 0.47; AUCPPV: 0.50), despite the decrease in the threshold value of SVV and PPV to initiate an overload of volume during one-lung ventilation, in lateral position and open chest. CONCLUSIONS: The results obtained show that the values of the dynamic parameters of volume response (SVV≥8% and PPV≥10%) do not discriminate against responders patients and non-responders during open lung resection surgery.

The case concerns a 58 year-old female with no medical history of interest who consulted due to binocular diplopia of one week onset. It was associated with costal pain, dyspnoea, intense asthenia and weight loss of 2 months onset. In the blood analysis in the Emergency Department it showed hypercalcaemia, renal failure, and bicytopenia. The chest x-ray showed lytic bone lesions that initially lead to multiple myeloma with extra-osseous involvement. In addition to the corresponding study, in case of horizontal diplopia, a cranial CT scan without contrast was performed where an adjacent lesion to the lateral wall of the left orbit is observed. This was of soft tissue density, and included the external rectus muscle that exerts a mass effect on the optic nerve by displacing it medially. Many lytic bone diffuse lesions with salt and pepper pattern were found in the calotte. A rectus lateral muscle and bone biopsy of the sacral wing was performed, resulting in metastasis of carcinoma compatible with mammary origin. An atypical case is presented of horizontal diplopia in the context of a patient with a severe constitutional picture with no established diagnosis, in which the biopsy of the lateral rectum was key to the confirmation diagnosis.

Necremnus tutae is native to the Mediterranean region where it has been observed in greenhouses parasitizing the invasive Tuta absoluta on tomato. The objective of the present study was to determine whether augmentative releases of N. tutae can improve existing biological control of T. absoluta based on predation by Nesidicoris tenuis. Two experiments were carried out, of which the first evaluated different N. tutae release rates (1 and 2 N. tutae m-2 week-1). The parasitoid reduced plant and fruit damage, especially at the higher rate. However, such reduction was considered insufficient given the large numbers of parasitoids needed and still unacceptable level of fruit damage. The second experiment focused on combining the most efficient rate of N. tutae of those evaluated during the first experiment, with the pre- and post-planting release of N. tenuis and supplemental additions of Ephestia kuehniella eggs. Addition of N. tutae decreased leaf damage by T. absoluta regardless the release method for N. tenuis, but the pre-plant release of N. tenuis alone was sufficient to prevent fruit damage by T. absoluta. This suggested that the addition of N. tutae may not be necessary to obtain satisfactory control of T. absoluta following pre-plant application of N. tenuis, although different options for using N. tutae in commercial crops may still be possible.

There is a lack of data on pre-exposure prophylaxis (PrEP) effectiveness in Spain. We described the awareness of and willingness to use PrEP and examined potential barriers and facilitators to their use among men who have sex with men recruited either online or in voluntary HIV testing centers in Spain. Nearly a third of men (28.7 %) were aware of PrEP and 57.6 % said they would be willing to use it if available, 16.6 % saying they would be unwilling to use PrEP and 25.8 % not being sure. Men who had heard of PrEP were more forceful in their opinions on willingness to use PrEP (willing/not willing: 29.8 %/32.6 % vs. don't know: 21.8 %). The greatest consensus regarding more acceptable PrEP attributes was in the mode of delivery and its cost. Doctors (91 %) or pharmacists (85.3 %) were the preferred providers. The results confirm the need to inform and educate on PrEP and define implementation strategies.

This paper analyses late presentation (LP) of HIV infection, and its determinants, among men who have sex with men (MSM) in Spain, newly diagnosed with HIV (2003-2011) in 15 sexually transmitted infection/HIV counselling and testing clinics. LP was defined as <350 CD4 cells/µL or AIDS. In total, 3,081 MSM were included (2,499 having CD4/AIDS); overall LP was 25.3%. LP was higher in men older than 34 years, those not previously HIV-tested (adjusted odds ratio (aOR):3.1; 95% confidence intervals (CI):2.3-4.2) , and those tested > 12 months before diagnosis (12-24 months (aOR:1.4; 95% CI:1.0-2.0); > 24 months (aOR:2.2; 95% CI:1.7-3.0)). LP was less likely in MSM reporting a known HIV-infected partner as infection source or symptoms compatible with acute retroviral syndrome. 'Region of birth' interacted with 'educational level' and 'steady partner as infection source': only African and Latin-American MSM with low educational level were more likely to present late; Latin-American men attributing their infection to steady partner, but no other MSM, had LP more frequently. In Spain, HIV testing among MSM should be promoted, especially those > 34 years old and migrants with low educational level. The current recommendation that MSM be tested at least once a year is appropriate.

During 2000 to 2009, data on people undergoing HIV testing and on those newly diagnosed with HIV were collected in a network of 20 Spanish clinics specialising in sexually transmitted infections and/or HIV testing and counselling. The number of tests performed, overall and disaggregated by different variables, was obtained. HIV prevalence among first-time testers and HIV incidence among repeat testers were calculated. To evaluate trends, joinpoint regression models were fitted. In total, 236,939 HIV tests were performed for 165,745 individuals. Overall HIV prevalence among persons seeking HIV testing was 2.5% (95% CI: 2.4 to 2.6). Prevalence was highest in male sex workers who had sex with other men (19.0% (95% CI: 16.7 to 21.4)) and was lowest in female sex workers (0.8% (95% CI: 0.7 to 0.9)). Significant trends in prevalence were observed in men who have sex with men (MSM) (increasing) and heterosexual individuals (decreasing). The incidence analysis included 30,679 persons, 64,104 person-years (py) of follow-up and 642 seroconversions. The overall incidence rate (IR) was 1.0/100 py (95% CI: 0.9/100 to 1.1/100). Incidence was significantly higher in men and transgender females than in women (1.8/100 py (95% CI: 1.6 to 1.9), 1.2/100 py (95% CI: 0.5 to 2.8) and 0.1/100 py (95% CI: 0.09 to 0.2) respectively) and increased with age until 3539 years. IRs in MSM and people who inject drugs were significantly greater than in heterosexual individuals (2.5/100 py (95% CI: 2.3 to 2.7), 1.6/100 py (95% CI: 1.1 to 2.2) and 0.1/100 py (95% CI: 0.09 to 0.2) respectively), and an upward trend was observed in MSM. Our results call for HIV prevention to be reinforced in MSM and transgender women in Spain.

PURPOSE: To describe a staining technique that will enhance the visualization of non-absorbable T-Flux implants. METHODS: The technique was applied to non-absorbable T-Flux implants. The implants were submerged for 5 to 10 minutes in a sodium fluorescein solution, and dried with a sponge when removed from the solution. DISCUSSION: This is a very simple and easy procedure that uses a common fluorescein solution to enhance the contrast between the surgical field and a transparent implant used in deep sclerectomy. This colour technique will decrease the risk of loss of the implant in the surgical field.

BACKGROUND: Leukotrienes (LT), isoprostanes, and nitrites/nitrates are biomarkers of airway inflammation and oxidative stress that can be detected in exhaled breath condensate (EBC). The aim of this study was to evaluate LTB4, LTE4, 8-isoprostane, and nitrite/nitrate levels in the EBC of healthy and wheezing preschool children. METHODS: We included 21 healthy nonatopic children and 25 patients with recurrent wheezing episodes in a cross-sectional study. LTB4, LTE4, and 8-isoprostane concentrations were measured directly in EBC using a specific enzyme immunoassay; nitrite/nitrate concentrations were measured using a colorimetric assay. RESULTS: LTB4 concentrations were higher in children with wheezing episodes than in healthy controls (76 pg/mL vs 20 pg/mL, P < .001). LTE4 was increased in children with wheezing episodes than in healthy controls (68 pg/mL vs 35 pg/mL, P < .001). Nitrite concentrations were higher in children with wheezing episodes than in healthy controls (14 pg/mL vs 9.7 pg/mL, P < .03). We found no differences in 8-isoprostane and nitrate concentrations between the patients and the healthy controls. CONCLUSIONS: Our findings suggest that EBC is a suitable noninvasive method for the assessment of airway inflammation and oxidative stress in preschool children. Levels of LTB4, LTE4, and nitrites were higher in children with recurrent wheezing episodes than in healthy controls.

BACKGROUND: There are no data on the incidence and persistence of high-risk human papillomavirus (HR-HPV) infections in female sex workers (FSWs). We aimed to describe and compare the rates of incidence and persistence of HR-HPV infections in FSWs and women from the general population (WGP) who attended healthcare facilities between May 2003 and December 2006 in Alicante, Spain. METHODS: Women with an established HR-HPV infection at study entry were evaluated for the analysis of HR-HPV persistence, and those testing negative for HR-HPV infection at entry were evaluated for the analysis of incidence. HR-HPV infection was determined by the Digene HC2 HR HPV DNA Test. RESULTS: A total of 736 women - 592 WGP and 144 FSWs - were followed for a median of 16.8 months. Global incidence and persistence rates were 3.98 per 100 woman-years (95% confidence interval (CI) 2.91-5.45) and 26.81 per 100 woman-years (95% CI 20.08-35.79), respectively. In the multivariate analysis, only commercial sex work was associated with a statistically significant higher incidence (relative risk (RR) 4.72, 95% CI 2.45-9.09) and persistence (RR 1.93, 95% CI 1.08-3.46) of HR-HPV infection. CONCLUSIONS: Our data show that FSWs have both a higher incidence and a higher persistence of HR-HPV than WGP and should be prioritized in HPV-related cancer screening programs.

In Spain, neither the HIV nor the STI national surveillance systems collect information on HIV/STI co-infection. However, there are two networks based on HIV/STI clinics which gather this data. We describe HIV prevalence in men who have sex with men (MSM) diagnosed with infectious syphilis and/or gonorrhoea in 15 STI clinics; and concurrent diagnoses of STI in MSM newly diagnosed with HIV in 19 HIV/STI clinics. In total, 572 MSM were diagnosed with infectious syphilis and 580 with gonorrhoea during 2005-2007. HIV prevalence among syphilis and gonorrhoea cases was 29.8% and 15.2% respectively. In the multivariate analysis, HIV/syphilis co-infection was associated with being Latin American; having a history of STI; reporting exclusively anal intercourse; and having sex with casual or several types of partners. HIV and gonorrhoea co-infection was associated with age older than 45 years; having no education or only primary education completed; and having a history of STI. In total, 1,462 HIV infections were newly diagnosed among MSM during 2003-2007. Of these, 31.0% were diagnosed with other STI at the same time. Factors associated with STI co-infection among new HIV cases in MSM were being Latin American; and having sex with casual partners or with both steady and casual partners. In Spain, a considerable proportion of MSM are co-infected with HIV and STI.

BACKGROUND: The prevalence of asthma and bronchial hyper-responsiveness is greater in elite athletes than in the general population, and its association with mild airway inflammation has recently been reported. OBJECTIVE: To study the relationship between the type of sport practised at the highest levels of competition (on land or in water) and sputum induction cell counts in a group of healthy people and people with asthma. MATERIAL AND METHODS: In total, 50 athletes were enrolled. Medical history, results of methacholine challenge tests and sputum induced by hypertonic saline were analysed RESULTS: Full results were available for 43 athletes, who were classified by asthma diagnosis and type of sport (land or water sports). Nineteen were healthy (10 land and 9 water athletes) and 24 had asthma (13 land and 11 water athletes). Although the eosinophil counts of healthy people and people with asthma were significantly different (mean difference 3.1%, 95% CI 0.4 to 6.2, p = 0.008), analysis of variance showed no effect on eosinophil count for either diagnosis of asthma or type of sport. However, an effect was found for neutrophil counts (analysis of variance: F = 2.87, p = 0.04). There was also a significant correlation between neutrophil counts and both duration of training and bronchial hyper-responsiveness among athletes exposed to water (Spearman's rank correlations, 0.36 and 0.47, p = 0.04 and 0.04, respectively). CONCLUSIONS: Elite athletes who practice water sports have mild neutrophilic inflammation, whether or not asthma is present, related to the degree of bronchial hyper-reactivity and the duration of training in pool water.

Viscoelastics or ophthalmic viscosurgical devices are routinely used during anterior segment surgery and also in posterior segment surgery. Studies of the harmful effects of phacoemulsification on corneal endothelial cells suggest that much of this damage is mediated by free radicals. In this study, we compare the possible effects against lipid peroxidation in the retina of three different viscoelastic substances: Viscoat, Healon and Visiol. Herein we demonstrate for the first time that viscoelastics are effective to protect the retina against lipid peroxidation, as can be seen by the slight increase of malondialdehyde in the homogenates incubated with viscoelastic exposed to light and to a temperature of 37 degrees C when compared with the control homogenates.

The objective of the present study was to investigate the kinetics of high doses of inhaled steroid fluticasone in comparison with oral steroid prednisone on plasma protein leakage and bronchial eosinophilia in adults with moderate asthma exacerbations. The study design was a randomised, double-blind, placebo-controlled prospective trial. In total, 45 patients treated at the emergency department for moderate asthma exacerbations were recruited and 39 were assigned to receive fluticasone and placebo of prednisone (19 patients), or prednisone and placebo of fluticasone (20 patients). Medication was administered to all patients via a metered-dose inhaler and spacer (16 puffs; 4,000 microg.day(-1) or placebo) plus one pill (prednisone 30 mg.day(-1) or placebo). Spirometry and induced sputum for differential cell counts, albumin and alpha(2)-macroglobulin levels and blood eosinophils, interleukin-5 and granulocyte-macrophage colony-stimulating factor levels were obtained before treatment and at 2, 6 and 24 h after treatment. Symptoms clearly improved after 24 h in both groups. No differences were seen between groups in peak expiratory flow or forced expiratory flow in one second, which improved progressively but then decayed slightly after 24 h. Eosinophil counts in sputum also improved over time in both groups. The effect was faster with fluticasone than with prednisone, but was partially lost at 24 h. However, plasma proteins in sputum and eosinophil count in blood both decreased until 24 h, with no significant differences between groups. There was no correlation between eosinophil counts and plasmatic protein levels. In conclusion, both treatments improved symptoms, airway obstruction and inflammation, and plasma protein leakage at 24 h. Prednisone reduced blood eosinophil counts, while fluticasone reduced airway eosinophil counts, suggesting that the anti-inflammatory performance of fluticasone is exerted locally.

INTRODUCTION: Anemia is related to chronic and inflammatory diseases. Moreover, it is a factor of worse outcome in heart failure or myocardial infarction. Despite the importance of hemoglobin as a globular oxygen carrying protein, there are few studies on anemia and chronic obstructive pulmonary disease (COPD). OBJECTIVE: To determine the frequency and the characteristics of the anemia in COPD patients admitted to a tertiary hospital within a one year period. METHODS: Anthropometric and clinical data, tobacco habit, lung function tests, arterial blood gases and a basic study of anemia (BSA) were collected from digital clinical files. RESULTS: A total of 177 patients were enrolled. Mean age was 70 (range 44-95), FEV1 was 35 (15%) and hemoglobin (Hb) 136(22) g/dl. Sixty-six (37%) patients had chronic respiratory failure (CRF) and 59 (33%) were receiving long-term oxygen therapy. A total of 56 (31%) had anemia (Hb < 130 g/dl in men or < 120 g/dl in women) with a mean Hb of 111(13). Anemia was normocytic normochromic in 32 cases (58%). BSA was obtained in 24 patients (42.85%) and showed that 10 patients (41%) had anemia of chronic disease, 6 patients (25%) had iron deficiency and 8 (34%) had other causes. It should be mentioned that 35 patients (53%) had CRF had anemia but only 8 patients had erythrocytosis (4.5%). CONCLUSION: Anemia was frequent in these patients and was an underdiagnosed comorbidity.

Ninety, seven- to 10-day-old calves were allocated to three groups of 30 and treated daily for seven days with either 100 microg/kg halofuginone hydrobromide or 2.5 mg/kg decoquinate orally or left untreated as controls. The levels of diarrhoea and dehydration were monitored daily for 28 days from the first day of treatment (day 0) and samples of faeces were collected on days 0, 7, 14, 21 and 28, to quantify the excretion of Cryptosporidium parvum oocysts. The calves were weighed on days 3 and 28. The treatments had no effect on the levels of diarrhoea or dehydration, the proportions of diarrhoeic calves or the proportions of calves shedding oocysts. However, unlike decoquinate, halofuginone significantly reduced the excretion of oocysts on day 7 (P<0.0001), and decoquinate increased the average daily weight gain of the calves (P=0.049).
