Abstract
Dysregulation of cellular iron homeostasis in human breast cancer is reflected by the altered expression of regulatory proteins. The expressions of iron-related proteins in the mammary glands of cats and dogs have not been assessed. We evaluated the expressions of ferritin, ferroportin, hepcidin and transferrin receptor 1 in benign and malignant mammary gland lesions in cats and dogs. Iron deposition was detected using Perls' Prussian blue staining. We found no major differences in the expression of iron-related proteins between benign and malignant mammary gland lesions in either cats or dogs; however, these species exhibited accumulation of iron in benign lesions. Our findings provide an explanation for the absence of higher iron requirements by tumor cells in these animals. Further investigation of local iron homeostasis in cats and dogs and differences in their physiology compared to human breast cancer is required.

Abstract
BACKGROUND/OBJECTIVES To compare macronutrient intakes out of home-by location-to those at home and to investigate differences in total daily intakes between individuals consuming more than half of their daily energy out of home and those eating only at home. SUBJECTS/METHODS Data collected through 24-h recalls or diaries among 23 766 European adults. Participants were grouped as 'non-substantial', 'intermediate' and 'very substantial out-of-home' eaters based on energy intake out of home. Mean macronutrient intakes were estimated at home and out of home (overall, at restaurants, at work). Study/cohort-specific mean differences in total intakes between the 'very substantial out-of-home' and the 'at-home' eaters were estimated through linear regression and pooled estimates were derived. RESULTS At restaurants, men consumed 29% of their energy as fat, 15% as protein, 45% as carbohydrates and 11% as alcohol. Among women, fat contributed 33% of energy intake at restaurants, protein 16%, carbohydrates 45% and alcohol 6%. When eating at work, both sexes reported 30% of energy from fat and 55% from carbohydrates. Intakes at home were higher in fat and lower in carbohydrates and alcohol. Total daily intakes of the 'very substantial out-of-home' eaters were generally similar to those of individuals eating only at home, apart from lower carbohydrate and higher alcohol intakes among individuals eating at restaurants. CONCLUSIONS In a large population of adults from 11 European countries, eating at work was generally similar to eating at home. Alcoholic drinks were the primary contributors of higher daily energy intakes among individuals eating substantially at restaurants.

Abstract
Cystic fibrosis (CF) is the most common autosomal recessive disease in Caucasians. Although most cases are diagnosed in childhood, diagnosis in adults is apparently increasing. OBJECTIVE Evaluate the adult population with CF, comparing patients who were diagnosed before and after 18 years of age. METHODS Retrospective analysis of patients followed in three main medical centres in Portugal in 2012. Comparison of two groups: G1 - patients diagnosed at <18 years and G2 - patients diagnosed at ≥18 years. RESULTS 89 adults were identified: 61.8% in G1, 38.2% in G2. Gender distribution was similar in both groups. Average age in G2 was higher (38.3±8.4 vs. 26.8±6.1 years, p<0.001). Respiratory symptoms most frequently led to CF diagnosis in all patients, mainly in adulthood. There was a greater percentage of patients homozygous for the mutation delF508 in G1 (43.6 vs. 8.8%, p=0.02). Respiratory and pancreatic function, and body mass index (BMI) showed a higher severity in G1 (G1 vs. G2: FEV1: 54.6±27.3 vs. 29.9±64.6%, p=0.177; pancreatic insufficiency 72.7 vs. 26.5%, p<0.001; BMI 20.2±3.4 vs. 22.2±4.8, p=0.018). Pseudomonas aeruginosa and methicillin-sensitive Staphylococcus aureus were the most frequently isolated microorganisms. Lung transplantation rate was higher in G2 (20.6 vs. 10.9%, p=0.231) while mortality rate was higher in G1 (0 vs. 3.6%, p=0.261). Hospital admission rate was higher in G1 as well as mortality rate. CONCLUSION The results suggest that patients with CF diagnosed in childhood have characteristics that distinguish them from those diagnosed in adulthood, and these differences may have implications for diagnosis, prognosis and life expectancy.

Abstract
Autoimmune progesterone dermatitis (APD) is a rare skin condition with a varying morphology, which appears on a monthly basis during the luteal phase of the menstrual cycle and resolves spontaneously with the endogenous decrease in progesterone during menses. We present the case of 39-year-old multiparous Caucasian woman with generalised, self-limited urticaria in her perimenstrual period. APD was diagnosed in light of the cyclical nature of the symptoms. An intradermal test with the administration of 0.5 mg/mL of medroxyprogesterone acetate showed a positive result. She started using vaginal hormonal contraceptive that paradoxically exacerbate the symptoms, which ceased after the removal of the device. An oral combined contraceptive was initiated instead, with complete resolution of the symptoms. We share the case because of the rarity of the situation, emphasising the importance of a multidisciplinary team for differential diagnosis and patient follow up.

Abstract
BACKGROUND The increased asthma prevalence in westernized societies has been suggested to be related to environment exposures and lifestyle changes, particularly diet. We aimed to explore the association between dietary patterns and asthma prevalence, incidence and control in a nationally representative population. METHODS Data from 32,644 adults, 53% female, from the 4th Portuguese National Health Survey were analysed. Prevalence of asthma was 5.3%; 'current asthma', defined by asthma symptoms within previous year, 3.5%; 'current medicated asthma' defined by use of asthma medication within previous year, 3.0%; 'current severe asthma' defined by emergency visit because of asthma within previous year, 1.4%; and 'incident asthma', 0.2%. Dietary patterns (DP) were identified by latent trait models based on dietary intake. Unconditional logistic regression models were performed to analyse association between DP and asthma. Age, gender, education, family income, proxy reporting information, smoking, body mass index and physical activity level were analysed as confounders. RESULTS Two of the five identified DP were associated with asthma: 'high fat, sugar and salt' DP (positively correlated with pastry, chocolate and sweet desserts, candies, salty snacks, chips, fruit juices, soft drinks and alcoholic beverages consumption at snacks) was associated with asthma prevalence (OR = 1.13, 95% CI = 1.03, 1.24) and current severe asthma (OR = 1.23, 95% CI = 1.03, 1.48), while 'fish, fruit and vegetables' DP (positively correlated with fish, vegetables and fruit intake at meals) was negatively associated with current (OR = 0.84, 95% CI = 0.73, 0.98), and current medicated asthma (OR = 0.84, 95% CI = 0.72, 0.98), after adjustment for confounders. CONCLUSION & CLINICAL RELEVANCE Our results suggest a protective association between 'fish, vegetables and fruit' DP and current asthma and current medicated asthma, and a detrimental association between 'high fat, sugar and salt' DP and severe asthma prevalence, further supporting the rational for diet and lifestyle intervention studies in asthma based on whole dietary patterns and physical activity.

Abstract
Invasive micropapillary carcinoma (IMC) is a variant of infiltrating ductal carcinoma of the breast associated with poor outcome. In this study, we report 16 carcinomas of the feline mammary gland displaying histologic features that correspond to IMC of the breast in women. The clinicopathologic findings, overall survival time, disease-free survival time, and nuclear DNA content of these cats were compared with 65 more common invasive mammary carcinomas (other feline mammary carcinoma [FMC]) of nonspecified type. IMC was associated with larger tumor size, higher histologic grade ( P < .0001), deeper muscle invasion ( P = .004), and more frequent lymphovascular invasion and nodal metastases ( P = .009 and P = .001, respectively) than other FMCs. The aneuploid pattern was more frequent in IMC lesions. IMCs were also associated with lower survival rates. In summary, all cases of feline IMC were associated with clinicopathologic features of high biologic aggressiveness and should be classified as independent histologic types of FMC.

Abstract
INTRODUCTION The incidence of cystic fibrosis (CF) in Portugal is estimated at 1:8000 live births, although there is a lack of accurate statistics. The average life expectancy has been steadily increasing and CF is no longer an exclusively pediatric disease. OBJECTIVES Characterize the Portuguese adult population with the diagnosis of CF. METHODS Retrospective study based on clinical data of adult CF follow-up patients in the three specialized centers in Portugal where all of CF patients are seen, during 2012. RESULTS In 2012, there were 89 follow-up patients, 48 (54%) female and 15 (17%) lung transplanted. The average age was 31.3±9 years. The median age at diagnosis was 13 years and 34 (38%) were diagnosed in adulthood. The most frequent mutation was F508del (54.9%). Of the 89 patients, 49 patients (56%) had pancreatic insufficiency, 7 (9%) were diabetic and 42 patients (47.7%) had a body mass index (BMI) <20kg/m(2). As to ventilatory function, the average value of the forced expiratory volume in 1s (FEV1) was 58.45±28.59%. Only one of 77 patients did not have chronic airway infection. The most commonly isolated germ was methicillin-sensitive Staphylococcus aureus in 49 patients (55%). During 2012, two patients (2.2%) died at the ages of 21 and 36 years. DISCUSSION This study is the first description of the Portuguese adult CF population, which is particularly important since it can give us a better understanding of the real situation. A significant percentage of these patients were diagnosed in adulthood, which highlights the need for diagnostic suspicion in a patient with chronic lung disease and atypical manifestations.

Abstract
BACKGROUND Atopic dermatitis (AD) patients may benefit from using textiles coated with skin microbiome-modulating compounds. Chitosan, a natural biopolymer with immunomodulatory and antimicrobial properties, has been considered potentially useful. OBJECTIVE This randomized controlled trial assessed the clinical utility of chitosan-coated garment use in AD. METHODS Of the 102 patients screened, 78 adult and adolescents were randomly allocated to overnight use of chitosan-coated or uncoated cotton long-sleeved pyjama tops and pants for 8 weeks. The primary outcome was change in disease severity assessed by Scoring Atopic dermatitis index (SCORAD). Other outcomes were changes in quality of life, pruritus and sleep loss, days with need for rescue medication, number of flares and controlled weeks, and adverse events. Changes in total staphylococci and Staphylococcus aureus skin counts were also assessed. Comparisons were made using analysis of variance supplemented by repeated measures analysis for the primary outcome. Interaction term between time and intervention was used to compare time trends between groups. RESULTS Chitosan group improved SCORAD from baseline in 43.8%, (95%CI: 30.9 to 55.9), P = 0.01, placebo group in 16.5% (-21.6 to 54.6); P = 0.02 with no significant differences between groups; Dermatology Quality of life Index Score significantly improved in chitosan group (P = 0.02) and a significant increase of skin Coagulase negative Staphylococci (P = 0.02) was seen. CONCLUSIONS Chitosan coated textiles may impact on disease severity by modulating skin staphylococcal profile. Moreover, a potential effect in quality of life may be considered.

Abstract
REASONS FOR PERFORMING STUDY To investigate two protocols to provide antinociception in horses. OBJECTIVES To evaluate the antinociceptive effects of intravenous methadone combined with detomidine or acepromazine in adult horses. STUDY DESIGN Randomised, blinded, crossover study. METHODS Mechanical, thermal and electrical stimuli were applied to the dorsal left and right metacarpus and coronary band of the left thoracic limb, respectively. A thermal stimulus was applied caudal to the withers. The horses were treated with saline (C), a combination of methadone (0.2 mg/kg bwt) and detomidine (10 μg/kg bwt) (MD) or methadone (0.2 mg/kg bwt) and acepromazine (0.05 mg/kg bwt) (MA) at 1 week intervals. Nociceptive thresholds were measured before and at 15 min intervals until 150 min after treatment. Wilcoxon rank-sum and Wilcoxon signed rank tests were used to compare data between groups at each time point and over time within each group, followed by the Bonferroni method to adjust the P value. RESULTS The mechanical stimulus was the most sensitive test to differentiate the antinociceptive effects of the treatments. Mechanical thresholds were greater after MD than MA between 15 and 30 min and with both MD and MA these thresholds were greater than C from 15 to 60 min. Electrical and thermal limb thresholds were greater after MD than C at 15 and 45 min and at 15, 30, 45, 75 and 105 min, respectively. Thermal limb thresholds were greater with MA than C at 30 min. Thoracic thermal threshold in MD and MA were higher than C at 45, 75, 90 and 120 min and from 30 to 75 min, respectively. CONCLUSIONS Methadone and acepromazine produced less pronounced mechanical antinociception than MD.
