Prospective external validation of IOTA methods for classifying adnexal masses and retrospective assessment of two-step strategy using benign descriptors and ADNEX: a Portuguese multicenter study.

OBJECTIVE: This study aimed to externally and prospectively validate the International Ovarian Tumor Analysis (IOTA) Simple Rules (SRs), Logistic Regression model 2 (LR2) and Assessment of Different NEoplasias in the adneXa (ADNEX) in a Portuguese population, comparing them with operator subjective assessment (SA), Risk-of-Malignancy Index (RMI), as well as with each other. This study also aimed to retrospectively validate IOTA two-step strategy, using modified benign descriptors (MBDs) followed by the application of ADNEX in cases where MBDs were not applicable (MBDs + ADNEX). METHODS: In this multicenter diagnostic accuracy study, conducted between January 2016 and December 2021, three tertiary referral centers prospectively included consecutive patients with ultrasound diagnosis of at least one adnexal tumor who underwent surgery. All ultrasound assessments were performed by level II or III sonologists with IOTA certification. Patient clinical data and serum cancer antigen (CA125) levels were collected from the hospital databases. Each adnexal mass was classified as benign or malignant using SA, RMI, IOTA SRs, LR2 and ADNEX (with and without CA125). The reference standard was histopathological diagnosis. In the second phase, all adnexal tumors were retrospectively classified using the two-step strategy (MBDs + ADNEX). The sensitivity, specificity, positive (PPV) and negative predictive value (NPV), positive (LR+) and negative likelihood ratio (LR-) as well as overall accuracy were determined for SA, RMI, IOTA SRs, LR2, ADNEX and two-step strategy (MBDs + ADNEX). Receiver-operator characteristic curves were constructed and corresponding areas under the curve (AUC) determined for RMI, LR2 and ADNEX and two-step strategy (MBDs + ADNEX). The ADNEX calibration plots were constructed and estimated by LOESS smoother. RESULTS: Of the 571 included patients, 428 had benign disease, 42 borderline ovarian tumors, 93 primary invasive adnexal cancers and 8 metastatic tumors in adnexa (malignancy prevalence: 25.0%). The operator SA had an overall sensitivity of 97.9% and a specificity of 83.6% for distinguishing between benign and malignant lesions. RMI showed high specificity (95.6%) but very low sensitivity (58.7%), with an AUC of 0.913. The IOTA SRs were applicable in 80.0% of patients, with a sensitivity of 94.8% and a specificity of 98.6%. LR2 revealed a sensitivity of 84.6%, a specificity of 86.9% and an AUC of 0.939, at the malignancy risk cut-off of 10%. At the same cut-off, ADNEX with and without CA125 had a sensitivity of 95.8% and 98.6%, respectively, and a specificity of 82.5% and 79.7%, respectively. The AUC of ADNEX with vs. without CA125 was 0.962 vs. 0.960. The ADNEX model provided heterogeneous results in distinguishing between benign and different subtypes of malignancy, with the highest AUC (0.991) for discriminating benign masses from primary adnexal cancer stage II-IV, and the lowest AUC (0.696) for distinguishing primary adnexal cancer stage I and metastatic lesion in adnexa. The ADNEX calibration plots suggested an underestimation of the predicted risk in relation with the observed proportion of malignancies. The MBDs were applicable in 26.3% of cases (150/571 tumors, none of which were malignant). Similar to the ADNEX model applied in all patients, the two-step strategy using ADNEX in the second step only, with and without CA125, had an AUC of 0.964 and 0.961, respectively. CONCLUSIONS: Our results showed a good to excellent performance of the IOTA methods in the studied Portuguese population, outperforming RMI. ADNEX was superior in accuracy, but interpretation of its ability to distinguish malignant subtypes was fundamentally limited not only by sample size but also by large differences in the prevalence of tumor subtypes. The IOTA MBDs have been shown to be reliable in identifying benign disease. The two-step strategy based on the application of MBDs, followed by the ADNEX model if MBDs are not applicable, has proven to be suitable for daily practice circumventing the need to use electronic support in all patients.

Obstructive Sleep Apnea: a risk for uncontrolled and more severe asthma in adults that we should keep an eye on.

Summary: Background. Asthma control can be influenced by several factors, including obstructive sleep apnea (OSA). The literature reports variable prevalence and magnitude of OSA impact on asthma outcomes. The aim of our study is to analyze the frequency of high-risk for OSA in asthma patients and its impact on disease severity and control. Methods. We conducted a cross-sectional study at an Allergy Department with adult asthma patients recruited while undergoing routine lung function tests. Data on sex, age, body mass index, allergen sensitization, smoking habits, risk of OSA (using the Berlin questionnaire), rhinitis control (through CARAT), asthma severity (based on GINA 2023), asthma control (using the ACT), adherence to asthma treatment (through Treatment Adherence Measure) and pulmonary function test results were collected. Results. We included 216 patients, predominantly women (70.4%), with a median (P25-P75) age of 29.0 (21.0-45.0) years, of whom 28.2% were on GINA treatment levels 4-5. In 75.5% of cases asthma was controlled. High-risk for OSA was identified in 21.8% of patients. Asthma patients with high-risk for OSA were more likely to have uncontrolled [(47.8%; n = 22) vs (15.8%; n = 26); p less than 0.001] and more severe disease [(44.7%; n = 21) vs (23.7%; n = 40), p = 0.006]. In multivariable analysis, high-risk for OSA (OR 2.81 [95%CI 1.1.28-6.17], p = 0.010), sex (women) (OR 5.21 [95% CI 1.70-15.96], p = 0.004), uncontrolled rhinitis (OR 3.65 [95%CI 1.38-9.64], p = 0.009) and GINA asthma treatment steps 4-5 (OR 2.46 [95%CI 1.15-5.26], p = 0.020) were associated with uncontrolled asthma. Conclusions. It is crucial to actively investigate OSA, especially in patients with uncontrolled and more severe forms of asthma.

Retrospective study of risk markers for developing high-grade anal intraepithelial neoplasm in men who have sex with men living with HIV. / Estudio retrospectivo que evalúa marcadores de riesgo de desarrollar lesión escamosa intraepitelial anal de alto grado en hombres que tiene sexo con hombres y viven con el virus de inmunodeficiencia humana.

High-grade anal intraepithelial squamous lesion is significantly prevalent among men who have sex with men and are infected with the human immunodeficiency virus. This condition-the precursor to anal cancer-significantly increases the risk of developing it. Conversely, low-grade anal intraepithelial squamous typically follow a benign course and usually regress spontaneously. MATERIALS AND METHODS: To describe a population of men who have sex with men living with human immunodeficiency virus followed in a specialized anal cancer screening unit we conducted an observational, retrospective, and single-center study was. RESULTS: Ninety-four patients were analyzed, with a mean age of 39 ± 9 years, and a 87% positivity rate for high-risk human papillomavirus (HR-HPV). At the initial visit, 47% presented with low-grade squamous intraepithelial lesions. The progression rate to high-grade squamous intraepithelial lesion was 37.2 per 100,000 patients/year. None of the patients developed anal cancer. Tobacco and alcohol consumption were associated with this progression. DISCUSSION: In this series, longer duration of HIV infection, tobacco and alcohol use and the presence of HR-HPV were significantly associated with the occurrence of high-grade intraepithelial lesions. A lower risk of progression was seen in patients with higher education. CONCLUSION: In men who have sex with men living with HIV, the association of factors such as smoking, alcohol, the presence of HR-HPV and an increased burden of human papillomavirus disease makes these patients more susceptible to develop high-grade anal squamous lesions.

Real-World Clinical, Psychosocial and Financial Burden of Atopic Dermatitis: Results from the Spanish Cohort of the MEASURE-AD Trial. / Carga clínica, psicosocial y económica de la dermatitis atópica en vida real: resultados de la cohorte española del estudio MEASURE-AD.

BACKGROUND: Atopic dermatitis (AD) is one of the most prevalent skin diseases, but there are numerous knowledge gaps surrounding the impact this disease has on quality of life (QoL), mental health, and out-of-pocket expenses involved in the management of AD. The available scientific evidence on the multidimensional burden of AD is usually based on studies with measures reported by patients themselves. METHODS: In this context, the MEASURE-AD trial was developed as a cross-sectional, multicenter, multinational trial using patient- and physician-reported measures to characterize the multidimensional burden of AD in adults with moderate-to-severe AD. RESULTS: This paper presents the results of the Spanish cohort. We found that Spanish adults with moderate-to-severe AD and high EASI score (21.1-72) had a significantly increased disease burden, high severity of symptoms such as itch and sleep disturbances, impaired mental health and QoL, higher use of health care resources, and more out-of-pocket expenses than patients with low EASI scores (0-7 or 7.1-21). CONCLUSIONS: This study provides information to better understand disease burden, and identify aspects to be improved in the management of AD.

Consensus on the diagnostic algorithm for chronic nodular prurigo. / Consenso sobre el algoritmo diagnóstico del prurigo crónico nodular.

Chronic nodular prurigo (CNP) is a chronic dermatological disease characterized by the presence of chronic pruritus and pruritic nodular lesions. The aim of this study was to reach consensus among a group of experts based on a non-systematic literature review and an algorithm for the clinical diagnosis of CNP. The resulting algorithm is structured in 3 blocks: 1) early identification of the patient with a possible diagnosis of CNP; 2) diagnosis and assessment of CNP; and 3) categorization of CNP (identification of the underlying causes or associated comorbidities). We believe that this clinical algorithm can facilitate the correct diagnosis of patients with CNP. Additionally, it raises awareness on the need for a multidisciplinary approach and specific treatment of CNP, steps of paramount importance to make better therapeutic decisions.

Effectiveness and safety of brodalumab in the treatment of plaque, scalp and palmoplantar psoriasis: A multicentre retrospective study in a Spanish population.

BACKGROUND AND OBJECTIVE: The data in clinical practice regarding the effectiveness and safety of brodalumab in psoriasis are scarce, especially at scalp and palmoplantar locations. The main objective was the percentage of patients achieving absolute PASI ≤3/ ≤1/ =0 for plaque psoriasis and the percentage of patients achieving an IGA 0-1/IGA 0 for the special locations at Week 52 of treatment. PATIENTS AND METHODS: Observational retrospective multicentre study in 28 Spanish Hospitals that included adult patients with plaque psoriasis treated with brodalumab, from September 2018 until March 2021. RESULTS: A total of 200 patients were included. The mean baseline PASI was 10.97 (±6.28) with a mean basal scalp (n = 58) and palmoplantar (n = 40) IGA of 2.10 (±0.97) and 2.15 (±1.26), respectively. At Week 52, 93.98%/75.90%/68.67% of patients reached an absolute PASI ≤3/ ≤1/ =0 in plaque psoriasis (n = 83), with a percentage of patients achieving scalp (n = 27) and palmoplantar (n = 19) IGA 0-1/IGA 0 of 96.3%/88.9% and 100%/88.9%, respectively. Fifteen per cent of patients reported any adverse events with candidiasis being the most reported (6%), but only 6% of the adverse events required the withdrawal. CONCLUSIONS: Brodalumab demonstrated high PASI and IGA responses and was well tolerated in clinical practice in plaque, scalp and palmoplantar psoriasis.

The impact of a drug allergy label in an internal medicine ward.

Summary: Background. Drug hypersensitivity reactions are presumably immune-mediated reactions that cause reproducible signs and/or symptoms. Overdiagnosis of drug allergy, frequently self-reported, is common and carries significant limitations. We intended to analyze the frequency and impact of drug allergy in hospitalized patients. Methods. A retrospective study was conducted in an Internal Medicine ward at a tertiary hospital in Portugal. All patients with a drug allergy report admitted within a 3-year period were included. Data were collected from their electronic medical records. Results. We found that 15.4% of patients had a report of drug allergy, with antibiotics being the most common (56.4%), followed by non-steroidal anti-inflammatory drugs (21.7%) and radiocontrast media (7.0%). The allergy report affected the clinical approach of 14.5% of patients by motivating the use of second-line agents, or the eviction of necessary procedures. The usage of alternative antibiotics entailed a cost increase of 2.4 times. There were 14.7% of patients to whom the suspected drug was administered: 87.0% tolerated and 13.0% developed a reaction. Only 1.9% were referred to our Allergy and Clinical Immunology department and proceeded in their allergy study. Conclusions. In this study, a considerable number of patients had a drug allergy label on their records. This label contributed to an increase in the cost of treatment, or the avoidance of necessary exams. However, disregarding an allergy record may lead to potentially life-threatening reactions that proper risk assessment could avoid. Further investigation should always be part of the follow-up routine of these patients, and better articulation between departments should be encouraged.

Ear identification: A multi-ethnic study sample.

The external human ear is considered to be highly variable among individuals. Hence, forensic applications could be explored for human identification. This research compares the usefulness of Cameriere's ear identification method, in samples originating from six different countries (Brazil, India, Japan, Russia, South Africa and Turkey) in order to examine possible differences in their accuracy values. A sample of 2,225 photographs of the external human ear (1,134 left and 1,091 right ears) from 1,411 individuals (633 females and 778 males) was collected. The samples included healthy subjects with no systemic disorders and without any craniofacial trauma, maxillofacial abnormalities, auricular anomalies, ear diseases or previous auricular surgery. Cameriere's ear identification method was applied and measurements were performed on the images of each ear, considering four anatomic regions: helix, antihelix, concha, and lobe. The quantified measurement values were converted into a proposed coded number system. A search for identical codes was accomplished to find out the distinctiveness of the morphology of the human ear. The combined codes of left and right ears of each of the 814 subjects were not repeated in this multi-ethnic study sample. Dirichlet's distribution and the inherent study equation showed that the probability of two different individuals having the same code (false-positive identification) was found to be <0.0007. Because of the distinctive metrics of the ratios of external human ears, studies with Cameriere's ear identification method may be valuable for human identification. Studying the differences between the left and right ears of the same individual and across different ethnic groups could contribute to the development of supplementary tools for human identification.

Improving the Management and Follow-up of Atopic Dermatitis: A Delphi Process Report of Consensus Between Hospital Dermatologists and Pharmacists. / Líneas de mejora asistencial entre dermatólogos y farmacéuticos hospitalarios para el manejo y seguimiento de la dermatitis atópica: consenso Delphi.

Managing atopic dermatitis, one of the most common dermatologic conditions, is often challenging. To establish consensus on recommendations for responding to various situations that arise when treating atopic dermatitis, a group of hospital pharmacists and dermatologists used the Delphi process. A scientific committee developed a Delphi survey with 2 blocks of questions to explore the group's views on 1) evaluating response to treatment in the patient with atopic dermatitis and 2) cooperation between the dermatology department and the hospital pharmacy service. The experts achieved an overall rate of consensus of 86% during the process. Conclusions were that dermatologists and hospital pharmacists must maintain good communication and coordinate their interventions to optimize the management of atopic dermatitis and patients' responses to treatment.

Preoperative staging of ovarian cancer: comparison between ultrasound, CT and whole-body diffusion-weighted MRI (ISAAC study).

OBJECTIVES: To compare the performance of transvaginal and transabdominal ultrasound with that of the first-line staging method (contrast-enhanced computed tomography (CT)) and a novel technique, whole-body magnetic resonance imaging with diffusion-weighted sequence (WB-DWI/MRI), in the assessment of peritoneal involvement (carcinomatosis), lymph-node staging and prediction of non-resectability in patients with suspected ovarian cancer. METHODS: Between March 2016 and October 2017, all consecutive patients with suspicion of ovarian cancer and surgery planned at a gynecological oncology center underwent preoperative staging and prediction of non-resectability with ultrasound, CT and WB-DWI/MRI. The evaluation followed a single, predefined protocol, assessing peritoneal spread at 19 sites and lymph-node metastasis at eight sites. The prediction of non-resectability was based on abdominal markers. Findings were compared to the reference standard (surgical findings and outcome and histopathological evaluation). RESULTS: Sixty-seven patients with confirmed ovarian cancer were analyzed. Among them, 51 (76%) had advanced-stage and 16 (24%) had early-stage ovarian cancer. Diagnostic laparoscopy only was performed in 16% (11/67) of the cases and laparotomy in 84% (56/67), with no residual disease at the end of surgery in 68% (38/56), residual disease ≤ 1 cm in 16% (9/56) and residual disease > 1 cm in 16% (9/56). Ultrasound and WB-DWI/MRI performed better than did CT in the assessment of overall peritoneal carcinomatosis (area under the receiver-operating-characteristics curve (AUC), 0.87, 0.86 and 0.77, respectively). Ultrasound was not inferior to CT (P = 0.002). For assessment of retroperitoneal lymph-node staging (AUC, 0.72-0.76) and prediction of non-resectability in the abdomen (AUC, 0.74-0.80), all three methods performed similarly. In general, ultrasound had higher or identical specificity to WB-DWI/MRI and CT at each of the 19 peritoneal sites evaluated, but lower or equal sensitivity in the abdomen. Compared with WB-DWI/MRI and CT, transvaginal ultrasound had higher accuracy (94% vs 91% and 85%, respectively) and sensitivity (94% vs 91% and 89%, respectively) in the detection of carcinomatosis in the pelvis. Better accuracy and sensitivity of ultrasound (93% and 100%) than WB-DWI/MRI (83% and 75%) and CT (84% and 88%) in the evaluation of deep rectosigmoid wall infiltration, in particular, supports the potential role of ultrasound in planning rectosigmoid resection. In contrast, for the bowel serosal and mesenterial assessment, abdominal ultrasound had the lowest accuracy (70%, 78% and 79%, respectively) and sensitivity (42%, 65% and 65%, respectively). CONCLUSIONS: This is the first prospective study to document that, in experienced hands, ultrasound may be an alternative to WB-DWI/MRI and CT in ovarian cancer staging, including peritoneal and lymph-node evaluation and prediction of non-resectability based on abdominal markers of non-resectability. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Immunoallergic disorders in the elderly.

Summary: Although allergic diseases have become increasingly prevalent in the elderly, there are few data on this population. Through a retrospective analysis of the electronic medical records of patients aged 65 years and above followed in our Immunoallergology Unit, we aimed to characterize the immunoallergic diseases of the elderly. The most common disorders were respiratory diseases (n = 185; 50%), mucocutaneous diseases (n = 113; 31%), drug allergy (n = 31; 8%), food allergy (n = 9; 2%), and anaphylaxis (n = 9; 2%). Use of specific immunotherapy was residual (n = 2; 1%). There was an association between anaphylaxis and both, drug (p = 0.004) and food (p = 0.013) allergies. Non-allergic rhinitis and bronchial asthma were more frequent in females, and ACE inhibitors/ARB induced-angioedema in males. Recognizing the characteristics of immunoallergic diseases in the elderly and the specificities of this age group is paramount in providing these patients with the best possible care.

[Sexually Transmitted Infections During the First Wave of the COVID-19 Pandemic in Spain]. / Infecciones de transmisión sexual (ITS) durante el estado de alarma por la pandemia de COVID-19 en España.

OBJECTIVE: To describe changes in sexually transmitted infection (STI) diagnoses during the first wave of the COVID-19 pandemic in Spain. MATERIAL AND METHODS: We collected demographic, chronological, and clinical data for all patients seen for a possible STI at Hospital La Paz, Centro Sanitario Sandoval, and Centro de Diagnóstico Médico in Madrid and Hospital Costa del Sol in Malaga between March 14, 2020 and June 30, 2020. RESULTS: We identified 674 STI diagnoses. The median age of the patients was 33 years. Most cases were observed among people aged 30 to 40 years and among men who have sex with men. The most common diagnoses were proctitis (36.5%), syphilis (16%), nongonococcal (13.3%) and gonococcal (11.3%) urethritis, genital herpes (8.8%), vulvovaginitis/cervicitis (8.3%), and genital warts (4.2%). A microbiologically confirmed diagnosis was on record for 77% of cases. The main microorganisms identified were Chlamydia trachomatis (35.7%), Neisseria gonorrhoeae (31.4%) and Treponema pallidum (17.2%). The number of STI diagnoses increased after the easing of lockdown restrictions, which resulted in greater freedom of movement and more consultations. On comparing the 2019 and 2020 STI registries from Centro Sanitario Sandoval and Hospital La Paz for the period March to June, we observed reductions (of up to 81%) in all STI diagnoses. CONCLUSIONS: Physical distancing and movement restrictions appear to have resulted in a reduction in the incidence of STIs, although these measures did not completely eliminate sexual risk behaviors.

Upregulation of miR-3195, miR-3687 and miR-4417 is associated with castration-resistant prostate cancer.

PURPOSE: Prostate cancer (PCa) is a leading cause of cancer-related death. Upon androgen-deprivation therapy, the disease may progress further to castration-resistant PCa (CRPC) with a poor prognosis. MicroRNAs (miRNAs) are small non-coding RNAs, which play crucial roles in gene regulation. The aim of our study is to find CRPC-associated miRNAs and to evaluate their functional role. METHODS: In this study, 23 benign prostatic hyperplasia (BPH), 76 primary PCa, and 35 CRPC specimens were included. Total RNA extracted from tissue sections was used for miRNA profiling on the Affymetrix GSC 3000 platform. Subsequently, stem-loop RT-qPCR analysis was performed to validate the expression levels of selected miRNAs. PCa cell lines were transfected with miRNA mimics or inhibitors to evaluate the effects on cell proliferation, cell migration and cell invasion. RESULTS: In our profiling study, several miRNAs were found to be deregulated in CRPC compared to primary PCa tissue, of which miR-205 (- 4.5-fold; p = 0.0009), miR-92b (- 3.1 fold; p < 0.0001) were downregulated and miR-3195 (5.6-fold; p < 0.0001), miR-3687 (8.7-fold; p = 0.0006) and miR-4417 (5.0-fold; p = 0.0005) were most upregulated. While KLK3, miR-21 and miR-141 expression levels in androgen-treated VCaP and LNCaP cells were increased, the expression levels of miR-3687 and miR-4417 were reduced. None of the miRNAs were androgen-regulated in the AR-negative PC3 cell line. Overexpression of miR-3687 reduced cell migration and cell invasion, whilst miR-3195 enhanced cell migration. CONCLUSION: We have identified several novel deregulated miRNAs in CRPC tissue, including two microRNAs that are potentially involved in tumor invasion. Our data support the hypothesized involvement of miRNAs in PCa tumorigenesis and progression to CRPC. The applicability of these miRNAs as novel biomarkers for CRPC remains to be further investigated.

Factors Associated With Asthma Control in 121 Preschool Children.

BACKGROUND AND OBJECTIVES: Data on risk factors for uncontrolled asthma in preschool children are controversial. Objective: This study aims to explore the association between clinical and functional parameters and the lack of asthma control in preschool children. METHODS: Children aged 3-5 years with asthma and healthy controls were recruited. A questionnaire was used to identify potential risk factors for uncontrolled asthma, as defined by the Global INitiative for Asthma criteria. Lung function and bronchial reversibility were evaluated through impulse oscillometry and spirometry. Adjusted odds ratios were estimated based on multivariable generalized additive regression models. The discriminative ability of the models was measured by the area under the receiver operating characteristic curve (AUC). RESULTS: The study population comprised 121 children (107 with asthma and 14 healthy controls). Fifty-three patients (50%) had uncontrolled asthma. After adjustment, the variables associated with an increased risk of lack of control were as follows: "More than 3 flare-ups in the last 12 months", "Moderate to severe rhinitis", and "Relative variation in postbronchodilator FVC and FEV1". The AUC of the final models that included variation in FVC or FEV1 were 0.82 and 0.81, respectively. The R5-20, R5-20%, and AX z-score values of the healthy group were lower than those of children with asthma. CONCLUSION: In preschool children, clinical and functional parameters are associated with uncontrolled asthma. More studies are needed to confirm the usefulness of impulse oscillometry.

Molecular Profile of Sensitization to Dermatophagoides pteronyssinus Dust Mite in Portugal.

BACKGROUND AND OBJECTIVES: To analyze component-resolved diagnosis of sensitization to Dermatophagoides pteronyssinus (Der p) in patients with respiratory allergy and the association between diagnostic findings and clinical severity in different geographical areas. METHODS: The study population comprised 217 patients (mean age, 25.85 [12.7] years; 51.16% female) selected from 13 centers in Portugal (5 from the North, n=65). All had allergic rhinitis with or without asthma and positive skin prick test results to at least 1 dust mite. Specific IgE (sIgE) to Der p, Dermatophagoides farinae, Lepidoglyphus destructor, Der p 1, Der p 2, Der p 10, and Der p 23 was determined using ImmunoCAP. The Mann-Whitney test was applied for the following comparisons: rhinitis vs rhinitis and asthma; mild vs moderate-to-severe rhinitis; North vs South. RESULTS: The prevalence of sensitization was 98.2% for Der p, and 72.4%, 89.4%, 9.7%, and 77% for Der p 1, Der p 2, Der p 10, and Der p 23, respectively. The corresponding median sIgE levels were 8.56, 17.7, 0.01, and 3.95 kUA/L. sIgE to all allergens was higher in patients with moderate-to-severe rhinitis and rhinitis with asthma (nonsignficant). Concentrations of sIgE to Der p 2 were significantly higher in the South than in the North (P=.0496). CONCLUSION: The most common sensitization in Portugal was to Der p. The highest prevalence and median sIgE level were observed for Der p 2. All sIgE values for molecular components were higher in more symptomatic patients (nonsignificant). Concentrations of sIgE to Der p 2 were higher in the South, probably because of the warmer temperature and/or the larger sample size.

Cross-cultural validation of the Portuguese from Portugal version of the Test for Respiratory and Asthma Control in Kids (TRACK) questionnaire.

SUMMARY: Introduction. The Test for Respiratory and Asthma Control in Kids (TRACK) is a tool to assess asthma control in preschool children. This study aims to validate the Portuguese from Portugal version of the TRACK questionnaire. Methods. A prospective cohort study was carried out to assess their psychometric characteristics. Caregivers of 141 children under age 5 with asthma symptoms were enrolled. Results. Internal reliability was close to 0.70 (Cronbach's α). The test-retest reliability was 0.87. TRACK scores were different between well, partially, and non-controlled asthma groups (p less than 0.001). Patients rated as having better control showed an increase in TRACK scores. Conclusions. The Portuguese version of the TRACK questionnaire is accurate and reliable for monitoring asthma control. Its use may help to overcome challenges with the management of this age group.

Sexually Transmitted Infections During the First Wave of the COVID-19 Pandemic in Spain.

OBJECTIVE: To describe changes in sexually transmitted infection (STI) diagnoses during the first wave of the COVID-19 pandemic in Spain. MATERIAL AND METHODS: We collected demographic, chronological, and clinical data for all patients seen for a possible STI at Hospital La Paz, Centro Sanitario Sandaval, and Centro de Diagnóstico Médico in Madrid and Hospital Costa del Sol in Malaga between March 14, 2020 and June 30, 2020. RESULTS: We identified 674 STI diagnoses. The median age of the patients was 33 years. Most cases were observed among people aged 30 to 40 years and among men who have sex with men.

OBJETIVO: Describir los cambios en el comportamiento de las ITS durante la situación de alerta sanitaria por la pandemia SARS-CoV-2. MATERIAL Y MÉTODOS: Se recogieron datos demográficos, cronológicos y clínicos de todos los pacientes que solicitaron atención médica por ITS en los hospitales La Paz y Costa del Sol, y los Centros Sandoval y de Diagnóstico Médico entre el 14/03/2020 y el 30/06/2020. RESULTADOS: Documentamos 674 casos de ITS. La mediana de edad fue de 33 años. El mayor porcentaje de casos se dio en el rango de 30-40 años y en hombres que tenían sexo con hombres. Los diagnósticos más frecuentes fueron: proctitis (36,5%), sífilis (16%), uretritis no gonocócica (13,3%) y gonocócica (11,3%), herpes genital (8,8%), vulvovaginitis/cervicitis (8,3%) y condilomas (4,2%).En 77% de los casos hubo confirmación microbiológica, siendo los microorganismos más frecuentes Chlamydia trachomatis (35,7%), Neisseria gonorrhoeae (31,4%) y Treponema pallidum (17,2%).Se constató un incremento del número de casos de ITS tras el desconfinamiento, explicable por las mayores libertades y el aumento de consultas. Comparando los registros de ITS del Centro Sandoval y el Hospital La Paz en los cuatrimestres de marzo a junio de 2019 frente a 2020, se observó una disminución en 2020 de todos los diagnósticos, de hasta un 81% menos que en 2019. CONCLUSIONES: Las medidas de distanciamiento y limitación de movilidad aparentemente generaron una disminución de la incidencia de ITS, pero sin llegar a una inhibición completa de las conductas sexuales de riesgo.

Short communication: Uterine leptospiral infection is strongly associated to strains of serogroup Sejroe on experimentally infected hamsters.

Leptospira infection is influenced by the host species and the bacterial strain involved. Important differences on their tissue distribution are referred, also depending on the host and the studied strain. Considering tissue distribution of leptospires the majority of the studies focus on a single strain, or strains from the same serogroup with different inoculation doses. Nevertheless, none had associated different serogroups with their tissue distribution. Thus, the present study aims to investigate the hypothesis that tissue distribution of Leptospira spp. on experimentally infected hamsters may vary according to the strain serogroup. Females of Golden Syrian hamsters were used for the experimental infection with Leptospira isolates (n = 13) belonging to serogroups Icterohaemorrhagiae (n = 8) and Sejroe (n = 5). PCRs were conducted in renal, hepatic and uterine tissue. Seven out of the thirteen studied hamsters presented acute clinical signs and were euthanized before the 21° day p.i. (strains VF237, VF52, U81, UFF-SG001, UFF-G19, UFF-B15, L1-130), while the others presented a subclinical infection. Regarding to the PCR results it was possible to observe that, all but one strain (UFF-SG001), which was detected on all the studied tissues, presented some differences on their tissue distribution. All strains could be detected on at least one tissue and a significant association was observed for the occurrence of the strains of serogroup Sejroe in uterus (p = 0.044). The results of the present study indicate that strains of serogroup Sejroe are strongly associated to uterine infection on experimentally infected hamsters.

Blood or skin: what is best in predicting cow's milk allergy diagnosis?

Summary: Cut-off values for both skin prick tests (SPT) and specific IgE (sIgE) levels for predicting cow´s milk allergy (CMA) diagnosis are not universally defined. This study is a retrospective analysis of consecutive children (0-18 years-old) with suspected CMA tested with SPT and sIgE for cow's milk (CM) and its fractions between 2016-2017. CMA diagnosis was defined by a positive oral food challenge or a highly suggestive clinical history of CMA and SPT and/or sIgE positive to CM and/or its fractions. One hundred and five patients were included, 58% males with a median age of 2.5 (P25-P75:1-6) years and the diagnosis was confirmed in 83 patients (79%). The variables associated with CMA diagnosis were SPT with CM (p minor 0,05) and casein (p minor 0,05) and all sIgE to CM and its fractions (alfa Lactalbumin, beta Lactoglobulin and casein; p minor 0,05 for all). Optimal cut39 off points (Youden's index) for CMA diagnosis were, for the mean wheal diameter, to CM milk of 4.5mm and to casein of 3mm. For sIgE levels the optimal cut-off points were: for CM of 4.36 kUA/L, alfa-lactalbumin of 1.6 kUA/L, beta-lactoglobulin of 1.7 kUA/L and for casein of 2.6 kUA/L. The role of SPT and sIgE levels to cow´s mlik and its fractions is unequivocal in CMA follow-up. Moreover, sIgE levels seem to be more discriminatory than SPT.

Asthma and COPD "overlap": a treatable trait or common several treatable-traits?

Summary: In the last years, disease classification of chronic respiratory diseases (CRD) has been vivaciously discussed and new concepts have been introduced, namely asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO). Controversially the GOLD consensus document of 2020 considered that we should no longer refer to ACO, as they constitute two different diseases that may share some common traits and clinical features. The treatable traits approach has numerous strengths that are applicable to several levels of health care. In this paper we review the application of the treatable traits to CRD and describe in detail the ones already identified in patients with asthma and COPD. Treatable traits in CRD can be divided in pulmonary, extra-pulmonary and behavior/lifestyle risk factors. Patients with both asthma and COPD patients have clearly recognized treatable traits in all these subtopics but it is notorious the severe and frequent exacerbations, the associated cardiovascular disease and the low health related quality of life and productivity of these patients.
