Fluctuations in Mediterranean Diet Adherence Pre- and Post-Pandemic: A Study of Portuguese Cohorts 2019-2024.

BACKGROUND/OBJECTIVES: The Mediterranean Diet (MD) is a lifestyle offering numerous health benefits. Nevertheless, the adherence to the MD is moderate even in Mediterranean countries. While sociodemographic factors influence MD adherence, additional impacts occurred due to the COVID-19 pandemic. This cross-sectional longitudinal study with three cohorts of Portuguese adults analyzes MD adherence before, during, and after the COVID-19 pandemic, and explores the effect of sociodemographic variables. METHODS: Sociodemographic factors, lifestyle habits, and MD adherence were assessed in the years 2019, 2021, and 2024 with an online self-filled questionnaire. MD adherence was measured with the Mediterranean Diet Adherence Screener (MEDAS). RESULTS: MEDAS score increased significantly (p < 0.05) from 2019 to 2021 (6.2 ± 0.7 to 7.7 ± 0.1), followed by a significant (p < 0.05) decrease in 2024 (7.2 ± 0.1) relative to 2019, which was more pronounced in participants with higher income. Accordingly, a trend in healthier food choices was observed followed by a decline in 2024. Of note is the significant increase in red meat consumption (p < 0.05) in 2024 relative to 2021. Respondents who consumed more red meat were mostly men, employed, or in a stable relationship. Most respondents practiced sport "Never or occasionally" in 2019 and 2021 (59.4 and 55.2%, respectively); in 2024, this category was significantly (p < 0.05) reduced (40.9%); men or higher-income participants were more likely to meet the recommended activity levels. CONCLUSIONS: This study reveals that the improvements in MD lifestyle during the pandemic were not sustained in 2024, as healthier habits formed during confinement were not fully integrated into long-term behavior. These findings strengthen the need for targeted public health interventions to promote the MD.

Cardiovascular Risk in Patients with Chronic Obstructive Pulmonary Disease: A Systematic Review.

Background/Objectives: A comprehensive and up-to-date review on cardiovascular disease (CVD) risk in patients with COPD is needed. Therefore, we aimed to systematically review the risk of a range of CVD in patients with COPD. Methods: We searched three databases (Pubmed, Web of Science, SCOPUS) from inception to September 2023 using terms related to COPD and CVD. Observational studies were included if they (1) were conducted in adults with a diagnosis of COPD based on the GOLD criteria, spirometry, physician diagnosis, or review of electronic health records; (2) reported the risk of CVD, namely of myocardial infarction (MI), ischaemic heart disease (IHD), atrial fibrillation (AF), heart failure, cerebrovascular disease, pulmonary hypertension, and peripheral vascular disease, compared with a control population using a measure of risk. A narrative synthesis was used. Results: Twenty-four studies from 2015 to 2023, mainly from Europe (n = 17), were included. A total of 3,485,392 patients with COPD (43.5-76.0% male; 63.9-73.5 yrs) and 31,480,333 (40.0-55.4% male, 49.3-70.0 yrs) controls were included. A higher risk of CVD in patients with COPD was evident regarding overall CVD, MI, IHD, heart failure, and angina. Higher risks of arrhythmia and AF, stroke, sudden cardiac death/arrest, pulmonary embolism, pulmonary hypertension, and peripheral vascular disease were also found, although based on a small amount of evidence. Conclusions: Patients with COPD have a higher risk of CVD than the general population or matched controls. This review underscores the need for vigilant and close monitoring of cardiovascular risk in individuals with COPD to inform more precise preventive strategies and targeted interventions to enhance their overall management.

Aerobic Exercise Training Protects Against Insulin Resistance, Despite Low-Sodium Diet-Induced Increased Inflammation and Visceral Adiposity.

Dietary sodium restriction increases plasma triglycerides (TG) and total cholesterol (TC) concentrations as well as causing insulin resistance and stimulation of the renin-angiotensin-aldosterone system (RAAS) and the sympathetic nervous system. Stimulation of the angiotensin II type-1 receptor (AT1) is associated with insulin resistance, inflammation, and the inhibition of adipogenesis. The current study investigated whether aerobic exercise training (AET) mitigates or inhibits the adverse effects of dietary sodium restriction on adiposity, inflammation, and insulin sensitivity in periepididymal adipose tissue. LDL receptor knockout mice were fed either a normal-sodium (NS; 1.27% NaCl) or a low-sodium (LS; 0.15% NaCl) diet and were either subjected to AET for 90 days or kept sedentary. Body mass, blood pressure (BP), hematocrit, plasma TC, TG, glucose and 24-hour urinary sodium (UNa) concentrations, insulin sensitivity, lipoprotein profile, histopathological analyses, and gene and protein expression were determined. The results were evaluated using two-way ANOVA. Differences were not observed in BP, hematocrit, diet consumption, and TC. The LS diet was found to enhance body mass, insulin resistance, plasma glucose, TG, LDL-C, and VLDL-TG and reduce UNa, HDL-C, and HDL-TG, showing a pro-atherogenic lipid profile. In periepididymal adipose tissue, the LS diet increased tissue mass, TG, TC, AT1 receptor, pro-inflammatory macro-phages contents, and the area of adipocytes; contrarily, the LS diet decreased anti-inflammatory macrophages, protein contents and the transcription of genes related to insulin sensitivity. The AET prevented insulin resistance, but did not protect against dyslipidemia, adipose tissue pro-inflammatory profile, increased tissue mass, AT1 receptor expression, TG, and TC induced by the LS diet.

Role of serum-specific immunoglobulin E in egg allergy: a comprehensive study of Portuguese pediatric patients.

INTRODUCTION: Food allergies represent a growing public health concern, particularly among children. This study aims to examine egg allergy in pediatric patients and analyze the value of serum-specific immunoglobulin E (sIgE) levels as predictive biomarkers for oral food challenge (OFC) outcomes. METHODS: Retrospective study, involving pediatric patients with suspected IgE-mediated egg allergy, conducted at a tertiary hospital. RESULTS: Data from 176 pediatric patients were analyzed, revealing a higher male prevalence (59.1%). Most cases (40.3%) presented symptoms in the first year of life, predominantly mucocutaneous symptoms (46%). OFC results varied across various forms of egg presentation, with cooked egg being the most frequently tested food. Positive OFCs were observed in 14.6% (n = 36) of cases. The study identified specific egg protein biomarkers for positive OFC, with ovalbumin for raw egg (sIgE > 1.28 KUA/L; area under the curve [AUC] = 0.917; sensitivity [S] 100%; and specificity [Sp] 92%), ovomucoid for cooked egg (sIgE > 0.99 KUA/L; AUC = 0.788, 95%; S: 79%; and Sp: 74%), and ovomucoid for baked egg (sIgE> 4.63 KUA/L; AUC = 0.870; S: 80%; and Sp: 85%) showing predictive capacities. CONCLUSIONS: The findings underscore the importance of considering various forms of egg presentation in the diagnosis and management of egg allergy. The findings highlight the valuable discriminatory capacity and provided reliable biomarkers, such as ovalbumin for raw egg and ovomucoid for cooked and baked egg in risk assessment, aiding in predicting OFC outcomes and helping clinicians to make informed decisions in diagnosing and managing egg allergies, thus improving patient care and quality of life.

Exploring the Relationship between Mediterranean Diet Adherence and Subjective Well-Being among Greek and Cypriot Adults.

Associations between subjective well-being (SWB) and dietary habits, employment status, and habitual activities are increasingly capturing the focus of researchers as well as policymakers worldwide. This study aimed to explore these associations in a sample of the population in Greece and Cyprus via an online survey. In total, 936 questionnaires (470: Cyprus, 466: Greece) were analyzed to study the associations between the Mediterranean Diet (MD) (using the 14-item MEDAS score, (14-MEDAS)), subjective well-being (SWB), and several socioeconomic factors. Key remarks of this survey highlight the positive impact of MD adherence on some well-being items. Namely, statistically significant differences were found on the following items: Satisfied with life (p < 0.001), Life worthwhile (p < 0.001), Feeling happy (p < 0.001), worried (p = 0.005), and depressed (p = 0.001), when comparing Low MD adherence (14-MEDAS < 5) to High MD adherence (14-MEDAS > 10). Other lifestyle habits such as spending time with friends and family, spending time in nature, and habitual physical activity were associated with aspects of SWB such as Life satisfaction, Life worthwhile, Feeling happy, and energetic. The findings support adherence to the MD, since it is associated with higher life satisfaction and self-reported happiness in this sample and should be considered when developing health policies on well-being.

Atherectomy - The Options, the Evidence, and When Should It Be Used.

The use of atherectomy for peripheral vascular interventions (PVIs) has increased exponentially and reached 18% of all PVI in the United States. The theoretical benefit on extensive arterial calcification relies on the concept of plaque modification and removal instead of displacement, as with other endovascular techniques. To date, there are no prospective studies comparing the different atherectomy technologies (directional, rotational, orbital, and laser). Moreover, most related prospective comparative studies have a small number of patients, and larger studies are single arm in patients with relatively mild to moderate disease burden. While available literature shows lower dissection risk and reduced bailout stenting, the superiority of this technology compared to other endovascular techniques has yet to be proven. Despite the lack of level 1 evidence to support its superiority, the lucrative reimbursement fueled the overuse of this technology as first-line therapy, particularly in office-based laboratories and ambulatory surgery centers. The use of atherectomy ought to be selective and complementary to other endovascular technologies, and individualized patient-level decision-making based on the practitioner's preference and expertise is essential to selectively incorporate atherectomy in managing complex atherosclerotic lesions.

Variations and inconsistencies in venous ablation coverage policies between single-state and multistate carriers in the United States.

BACKGROUND: Vein ablation is a common and effective treatment for patients with chronic venous insufficiency. The overuse of vein ablation despite the existence of evidence-based guidelines has resulted in insurance companies developing restrictive policies for coverage that create barriers to appropriate care. This study compares the insurance coverage by single-state carriers (SSCs) and multistate carriers (MSCs), highlighting the variations and inconsistencies in the various policies. METHODS: The American Venous Forum Venous Policy Navigator was reviewed for the various policies available in the United States. The policies were divided into SSCs and MSCs. The characteristics of the policies, including the anatomic and hemodynamic criteria for specific veins, duration of conservative treatment, disease severity, symptoms, and types of procedures covered, were compared between the two groups. SAS, version 9.4 (SAS Institute Inc) was used for statistical analysis. RESULTS: A total of 122 policies were analyzed and divided between SSCs (n = 85; 69.7%) and MSCs (n = 37; 30.3%). A significant variation was found in the size requirement for great saphenous vein ablation. Although 48% of the policies did not specify a size criterion, the remaining policies indicated a minimal size, ranging from 3 to 5.5 mm. However, no significant differences were found between SSCs and MSCs. Similar findings were encountered for the small and anterior accessory saphenous veins. MSCs were more likely to define a saphenous reflux time >500 ms compared with SSCs (81.1% vs 58.8%; P = .04). A significant difference was found between the SSCs and MSCs in the criteria for perforator ablation in terms of size and reflux time. MSCs were significantly more likely to provide coverage for mechanochemical ablation than were SSCs (24.3% vs 8.2%; P = .03). SSCs were more likely to require ≥12 weeks of compression stocking therapy than were MSCs (76.5% vs 48.7%; P = .01). No significant differences were found in the clinical indications between the two groups; however, MSCs were more likely to mention major hemorrhage than were SSCs. CONCLUSIONS: The results of this study highlight the variations in policies for venous ablation, in particular, the striking inconsistencies in size criteria. MSCs were more likely to cover mechanochemical ablation and require a shorter duration of conservative therapy before intervention compared with SSCs. Evidence-based guidance is needed to develop more coherent policies for venous ablation coverage.

The Effects of Pre-Season and Relationships with Physical, Physiological, Body Composition, and Load Markers: A Case Study Comparing Starters versus Non-Starters from an Elite Female Professional Soccer Team.

Background and Objectives: Research on female soccer players that analyzes playing status is scarce and has previously only examined load monitoring, while other markers, such as physical (i.e., strength, power, and agility), physiological (i.e., maximal oxygen uptake), and body composition (i.e., body fat mass, fat-free mass, body water, and phase angle) markers, warrant further investigation. Thus, the study aims were to (a) compare physical, physiological, body composition, and load markers between starters and non-starters; (b) compare measurements pre- and post-training intervention (five weeks); and (c) analyze any relationships between physical, physiological, body composition, and load markers in an elite female soccer team. Materials and Methods: Fourteen first-team players participated in the study (age 23.29 ± 3.19 years, weight 59.14 ± 6.87 kg, height 1.66 ± 0.08 m). Several physical (n = 15), physiological (n = 1), body composition (n = 11), and load markers (n = 14) were collected. In addition, participants were sub-divided into starters (n = 7) and non-starters (n = 7). Results: No differences were revealed between starters and non-starters in any of the examined variables. Moreover, following the training intervention, a significantly lower value was found for total body water/fat-free mass ratio (p = 0.043; ES = 0.582). In addition, there were several correlations detected between load and physical/physiological markers (n = 28); load and body composition markers (n = 6); physical/physiological and body composition markers (n = 34); and physical and physiological markers (n = 42). Conclusions: In conclusion, only a slight tendency of higher load values for starters than non-starters was observed. In addition, no differences in physical, physiological, and body composition markers were found between starters and non-starters, possibly suggesting that five weeks were not enough to improve such variables. Finally, the present results provide novel information assessing the effects of the pre-season in elite female Portuguese soccer players and contribute to a better understanding of the associations between different types of measurements.

Neurological syndromes and potential triggers associated with antibodies to neuronal surface antigens.

BACKGROUND: Autoantibodies against surface neuronal antigens have been associated with specific neurological presentations including autoimmune encephalitis (AE), with variable association with neoplasia and infections. METHODS: We described the phenotype and environmental associations of patients with neurological syndromes associated with antibodies against neuronal surface antigens who were referred to a tertiary center in the South of Brazil. All patients were tested for neuronal autoantibodies using cell-based assays. Clinical, radiological, and laboratory findings were retrospectively reviewed. RESULTS: We identified 16 patients, 15 had subacute, and one had a progressive disease course. Among patients with subacute onset, 11 (73 %) were N-Methyl-d-Aspartate receptor (NMDAr-IgG)+, 3 (20 %) were Leucine-rich Glioma-Inactivated-1 (LGI1-IgG)+, and 1 (6 %) was positive for Glycine receptor-IgG. The patient with a progressive disease course had antibodies against IgLON5. Most patients had disease onset in spring and summer suggesting environmental factors for the development of AE. Also, we observed a different pattern of brain lesions when NMDAr-IgG encephalitis followed herpes encephalitis and a previously unreported association with Rosai-Dorfman-Destombe disease. All patients with encephalopathy met criteria for possible AE and all proven NMDAr-IgG+ met criteria for NMDAr-IgG encephalitis. However, only one LGI1-IgG+ patient fulfilled clinical criteria for limbic encephalitis. All but one received high-dose intravenous methylprednisolone, 11 also had intravenous human immunoglobulin, and 4 plasma exchange. Furthermore, all patients received second-line immunotherapy. Importantly, most patients improved with immunotherapy, even when initiated later in the disease course. CONCLUSION: We identified seasonal variability associated with neuronal surface antibodies suggesting environmental triggers. Also, we described the coexistence of NMDAr-IgG encephalitis with histiocytosis. In our series, most patients received second-line immunotherapy. We observed neurologic improvement after treatment even in cases of delayed diagnosis. Increasing the recognition and availability of tests and treatments for these conditions is of paramount importance in low- and middle-income countries.

Reliability of telemedicine evaluation for EDSS functional systems in multiple sclerosis.

Introduction: There was an increase in telemedicine during the COVID-19 pandemic to follow patients with multiple sclerosis (MS). However, there is scarce data if online evaluations can cover important information assessed during in-clinic appointments, especially the Expanded Disability Status Score (EDSS). This study aims to develop a remote evaluation tool for EDSS functional systems and compare the performance with face-to-face evaluations. Methods: This was a single-center study that included all MS patients followed up at outpatient clinics of Hospital São Lucas Pontifícia Universidade Católica do Rio Grande do Sul, between April and August 2022. Initially, patients were routinely in-clinic evaluated by one trained neurologist for EDSS. After, patients were evaluated remotely without any information about the in-clinic EDSS results. We used a standardized interview with an interactive video platform to evaluate EDSS functional systems by telemedicine. Results: Forty-nine participants completed the two steps. Intra-class coefficient was 0.97 (95% CI: 0.95-0.98), concordance for EDSS below 4.0 was 0.87 (95% CI: 0.77-0.93) and ≥4.0 was 0.97 (95% CI: 0.89-0.99). There was perfect agreement in the final EDSS in 71.4% of the online and in-clinic evaluations. In the multivariate analysis, the visual (beta = 0.453; p = 0.003) and pyramidal (beta = 0.403; p = 0.009) systems contributed significantly to the difference in the final EDSS. Conclusion: The telemedicine tool created in this study can detect changes in functional systems with reliable results compared to in-clinic EDSS assessment. Telemedicine evaluations may reduce the number of in-clinic visits and the disease burden for patients with MS.

Association between Mediterranean lifestyle and perception of well-being and distress in a sample population of university Italian students.

We investigated the extent to which adherence to the Mediterranean diet (MD) in combination with Mediterranean lifestyle factors influenced students' perceptions of subjective well-being (SWB) and distress. 939 undergraduates completed a survey to assess sociodemographic and lifestyle characteristics, including adherence to the MD, depression, anxiety, stress, and SWB. Data were analysed with correlation, logistic, and multiple linear regression models. Higher adherence to MD correlated with better SWB. Fruit, red meat, sweet and caffeinated beverages contributed significantly. However, it was the combination of adherence to MD with other factors, including quality of social relationships, income, smoking, sleep, and physical activity that better predicted SWB. Our results confirm the positive influence of MD on SWB. However, they also suggest the need to consider perceptions of well-being by a more holistic approach that considers physical and social factors simultaneously to improve the development of more effective educational and motivational programmes.

Effects of Insect Consumption on Human Health: A Systematic Review of Human Studies.

Insects have been consumed as food in diverse cultures worldwide, gaining recognition as a sustainable and nutritious food source. This systematic review aims to update information on the impact of insect consumption on human health based on human randomized controlled trials (RCTs) and allergenicity assessment studies. Following PRISMA guidelines, studies published in the last 10 years were analyzed. From one-thousand and sixty-three retrieved references, nine RCTs and five allergenicity studies were analyzed. Post-prandial amino acid levels increased after insect protein consumption. In comparison with other protein sources, insect protein showed no significant differences in the area under the curve (AUC) values for essential amino acids but tended to have lower peaks and peak later. In terms of muscle protein synthesis, there were no significant differences between insect protein and other protein sources. Glucose levels did not differ; however, insulin levels were lower after the consumption of insect-based products. The effects on inflammatory markers and microbiota composition were inconclusive and the studies did not show significant effects on appetite regulation. Allergenicity assessments revealed a sensitisation and cross-reactivity between insect allergens and known allergens. A partial reduction of cross-allergenicity was observed via thermal processing. Insect protein is an adequate protein source with promising health benefits; however, further research is needed to fully understand its potential and optimise its inclusion into the human diet.

Rights for all? Living conditions and (de)citizenship of adults with intellectual and complex disabilities in Portugal.

BACKGROUND: In 2009, Portugal ratified the UN CRPD and a turn to a rights-based approach in disability law and policy has intensified since. It thus becomes important to understand whether these legal changes are furthering the social inclusion of adults with intellectual and complex disabilities. METHOD: Questionnaires were applied to a stratified sample of 127 adults with intellectual and complex disabilities attending social care and vocational training programmes across the country. RESULTS: Participants reported low rates of social participation, and many (49%) were found to live below the poverty line. High rates of discrimination and violence and feelings of loneliness and sadness were also reported, which can be strong indicators of the oppression that many of them daily endure. CONCLUSION: Adults with intellectual and complex disabilities in Portugal face exclusion, discrimination, and violence. The poverty and isolation in which many of them live compounds their (de)citizenship status in Portuguese society.

Role of the one-minute sit-to-stand test in the diagnosis of post COVID-19 condition: a prospective cohort study.

OBJECTIVE: To analyze the relationship between one-minute sit-to-stand test (1MSTST) parameters and a diagnosis of post COVID-19 condition in a cohort of patients who previously had COVID-19. METHODS: This was a prospective cohort study of patients with post COVID-19 condition referred for body plethysmography at a tertiary university hospital. Post COVID-19 condition was defined in accordance with the current WHO criteria. RESULTS: Fifty-three patients were analyzed. Of those, 25 (47.2%) met the clinical criteria for post COVID-19 condition. HR was lower in the patients with post COVID-19 condition than in those without it at 30 s after initiation of the 1MSTST (86.2 ± 14.3 bpm vs. 101.2 ± 14.7 bpm; p < 0.001) and at the end of the test (94.4 ± 18.2 bpm vs. 117.3 ± 15.3 bpm; p < 0.001). The ratio between HR at the end of the 1MSTST and age-predicted maximal HR (HRend/HRmax) was lower in the group of patients with post COVID-19 condition (p < 0.001). An HRend/HRmax of < 62.65% showed a sensitivity of 78.6% and a specificity of 82.0% for post COVID-19 condition. Mean SpO2 at the end of the 1MSTST was lower in the patients with post COVID-19 condition than in those without it (94.9 ± 3.6% vs. 96.8 ± 2.4%; p = 0.030). The former group of patients did fewer repetitions on the 1MSTST than did the latter (p = 0.020). CONCLUSIONS: Lower SpO2 and HR at the end of the 1MSTST, as well as lower HR at 30 s after initiation of the test, were associated with post COVID-19 condition. In the appropriate clinical setting, an HRend/HRmax of < 62.65% should raise awareness for the possibility of post COVID-19 condition.

Learning to estimate heart rate from accelerometer and user's demographics during physical exercises.

Getting prompt insights about health and well-being in a non-invasive way is one of the most popular features available on wearable devices. Among all vital signs available, heart rate (HR) monitoring is one of the most important since other measurements are based on it. Real-time HR estimation in wearables mostly relies on photoplethysmography (PPG), which is a fair technique to handle such a task. However, PPG is vulnerable to motion artifacts (MA). As a consequence, the HR estimated from PPG signals is strongly affected during physical exercises. Different approaches have been proposed to deal with this problem, however, they struggle to handle exercises with strong movements, such as a running session. In this paper, we present a new method for HR estimation in wearables that uses an accelerometer signal and user demographics to support the HR prediction when the PPG signal is affected by motion artifacts. This algorithm requires a tiny memory allocation and allows on-device personalization since the model parameters are finetuned in real time during workout executions. Also, the model may predict HR for a few minutes without using a PPG, which represents a useful contribution to an HR estimation pipeline. We evaluate our model on five different exercise datasets - performed on treadmills and in outdoor environments - and the results show that our method can improve the coverage of a PPG-based HR estimator while keeping a similar error performance, which is particularly useful to improve user experience.

Bio-Based Polyurethane Foams from Kraft Lignin with Improved Fire Resistance.

Rigid polyurethane foams (RPUFs) were synthesized using exclusively lignin-based polyol (LBP) obtained via the oxyalkylation of kraft lignin with propylene carbonate (PC). Using the design of experiments methodology combined with statistical analysis, the formulations were optimized to obtain a bio-based RPUF with low thermal conductivity and low apparent density to be used as a lightweight insulating material. The thermo-mechanical properties of the ensuing foams were compared with those of a commercial RPUF and a RPUF (RPUF-conv) produced using a conventional polyol. The bio-based RPUF obtained using the optimized formulation exhibited low thermal conductivity (0.0289 W/m·K), low density (33.2 kg/m3), and reasonable cell morphology. Although the bio-based RPUF has slightly lower thermo-oxidative stability and mechanical properties than RPUF-conv, it is still suitable for thermal insulation applications. In addition, the fire resistance of this bio-based foam has been improved, with its average heat release rate (HRR) reduced by 18.5% and its burn time extended by 25% compared to RPUF-conv. Overall, this bio-based RPUF has shown potential to replace petroleum-based RPUF as an insulating material. This is the first report regarding the use of 100% unpurified LBP obtained via the oxyalkylation of LignoBoost kraft lignin in the production of RPUFs.

Retrospective validation of parkland grading scale in a Latin-American high-volume center.

BACKGROUND: Increased complication rates following laparoscopic cholecystectomies have been described, likely related to surgical difficulty, anatomical variations, and gallbladder inflammation severity. Parkland Grading Scale (PGS) stratifies the severity of intraoperative findings to predict operative difficulty and complications. This study aims to validate PGS as a postoperative-outcome predictive tool, comparing its performance with Tokyo Guidelines Grading System (TGGS). METHODS: This is a single-center retrospective cohort study where PGS and TGGS performances were evaluated regarding intraoperative and postoperative outcomes. Both univariate and bivariate analyses were performed on each severity grading scale using STATA-SE 16.0 software. Additionally, we proposed a Logistic Regression Model for each scale. Their association with outcomes was compared between both scales by their Receiver Operating Characteristic Curve. RESULTS: 400 Patients were included. Grade 1 predominance was observed for both PGS and TGGS (47.36% and 25.3%, respectively). A positive association was observed between higher PGS grades and inpatient postoperative care, length of stay, ICU care, and antibiotic requirement. Based on the area under the ROC curve, better performance was observed for PGS over TGGS in the evaluated outcomes. CONCLUSION: PGS performed better than TGGS as a predictive tool for inpatient postoperative care, length of stay, ICU, and antibiotic requirement, especially in severe cases.

Pork-cat syndrome as cause of anaphylactic reaction to well-cooked meat / Síndrome gato-porco como causa de reação anafilática à carne cozida

Pork-cat syndrome is a rare clinical syndrome that can cause lifethreatening reactions. Occuring in patients allergic to cat dander, it involves cross-reactivity between cat and pig serum albumin. Cat allergy usually precedes food allergies, suggesting primary sensitization to cat serum albumin. Since these proteins are thermolabile, the reaction tends to be more severe in undercooked meat. A 27-year-old woman with persistent moderate-to-severe rhinoconjunctivitis since childhood reported 2 immediate mucocutaneous reactions after eating small amounts of pork. Skin prick tests with commercial extracts showed sensitization to pork, and prick-to-prick tests confirmed sensitization to raw pork and raw beef. Specific IgE was positive for pork, and ISAC microarray also showed sensitization to Fel d 2. SDS-PAGE and IgE immunoblotting assays were performed with raw and cooked pork extract and detected in a 60 kDa band. In the immunoblotting-inhibition assays, cat serum albumin completely inhibited IgE binding to pork extract. The patient underwent 2 oral food challenges with well-cooked pork and beef, both causing an anaphylactic reaction. The patient's history and in-vivo and in-vitro tests led to a diagnosis of pork-cat syndrome with clinical cross-reactivity to another mammalian serum albumin. This case should stimulate oral food challenges with other well-cooked mammalian meats in patients with this syndrome to establish a tolerance threshold and avoid possible unexpected anaphylactic reactions.

A síndrome gato-porco é rara e ocorre em doentes alérgicos ao pêlo de gato, envolvendo reatividade cruzada entre as albuminas séricas (AS) de gato e de porco. Normalmente, a doença respiratória a pêlo de gato precede a alergia alimentar, sugerindo uma sensibilização primária à albumina sérica de gato. Uma vez que estas proteínas são termolábeis, as reações tendem a ser mais graves com carnes menos cozidas. Mulher de 27 anos com rinoconjuntivite persistente moderada a grave desde a infância que refere duas reações imediatas mucocutâneas após ingestão de pequenas quantidades de carne de porco. Os testes cutâneos por picada com extratos comerciais mostraram sensibilização à carne de porco e os testes prick-to-prick confirmaram sensibilização à carne de porco e de vaca cruas. A IgE específica (sIgE) foi positiva para carne de porco, e o ensaio ISAC mostrou sensibilização a Fel d 2. Foram realizados ensaios de immunoblotting SDS-PAGE IgE com extratos de carne de porco crua e cozidas que detectaram uma banda de 60 kDA. Nos ensaios de inibição por immunoblotting a albumina sérica de gato produziu uma inibição total da ligação da IgE ao extrato de carne de porco. A doente realizou duas provas de provocação oral com carne de porco e de vaca cozidas, ambas positivas com desenvolvimento de reação anafilática. A história clínica, os testes in-vivo e in-vitro levaram ao diagnóstico de síndrome gato-porco com reatividade cruzada clínica a outras albuminas séricas de mamíferos. A síndrome gato-porco é rara e pode causar reações fatais. Este caso frisa a importância da realização de provas de provocação oral com outras carnes de mamíferos bem cozidas em doentes com esta síndrome, de forma a estabelecer um limiar de tolerância e evitar possíveis reações anafiláticas inesperadas.
