Head and neck cancer patient journey's health literacy: a multidisciplinary team perspective. VOICE study.

PURPOSE: Health literacy is a current Public Health priority in Portugal. The participation of well-informed patients in their care and shared decision making are essential, especially in chronic aggressive and debilitating pathologies such as recurrent or metastatic (R/M) Head and Neck Squamous Cell Carcinoma (HNSCC). AIMS: This study aimed to characterize R/M HNSCC patients' and caregivers' information needs identified by healthcare professionals (HCPs). METHODS: Two online Focus Groups, one with only medical doctors and the other with other HCPs involved in the treatment of R/M HNSCC patients, were conducted, using a modified Metaplan, Lean or adapted PDCA methodology. The discussions were audio recorded in full and content analysis was performed using ATLAS.ti qualitative data analysis software. RESULTS: Topics addressed were diagnosis, treatment, quality of life, and global evaluation. In general, all experts agreed that only essential information should be cautiously given, according to patients' and caregivers' wishes. It was consensual that patients are given the necessary information to adhere to treatment. Two main barriers were identified: one barrier was associated with verbal communication due to the lack of health literacy of these patients, and the other barrier regarded healthcare access. It was also considered important to remind patients of the daily and social activities that they could and should maintain, as well as providing sufficient social resources and problem-solving training to caregivers. CONCLUSIONS: This qualitative study highlights the complexity of R/M HNSCC patients' care. Immediate availability of psychologists and psychiatrists should be implemented in all centers that treat HNSCC patients. The differences found between the physicians' Focus Group and other HCPs' Focus Group in some of the addressed topics emphasize the importance of a multidisciplinary and holistic approach, in a biomedical model integrated with a biopsychosocial model.

Underreporting of work accidents associated with blood-borne risk factors.

BACKGROUND: Work accidents (WA) due to percutaneous or mucocutaneous injury are extremely frequent among health professionals. The notification of these accidents ensures not only the compliance with legal requirements, but it also enables health institutions to develop, implement and evaluate strategies to prevent them. This study aimed to estimate the proportion of underreporting of work accidents caused by percutaneous and mucocutaneous lesions in a hospital setting, as well as its determinants. METHODS: A self-administered questionnaire was made available to all hospital employees. Age, gender, professional category and type of service adjusted odds ratios (OR) and 95% confidence intervals (95%CI) were computed by multivariate logistic regression models. RESULTS: Underreporting of WA associated with biological risk factors was high, particularly in accidents by mucocutaneous injury (80.9%). Physicians were the professional category that least reported this type of work accidents (OR=4.64; 95%CI 2.20-9.78). The main determinants of underreporting were the underestimation of the risk of transmission and the excessive bureaucracy. CONCLUSIONS: The underreporting of work accidents associated with biological risk factors was considerable and it contributes to a high degree of uncertainty on accidents' characterization.

Determinants of the Use of Health and Fitness Mobile Apps by Patients With Asthma: Secondary Analysis of Observational Studies.

BACKGROUND: Health and fitness apps have potential benefits to improve self-management and disease control among patients with asthma. However, inconsistent use rates have been reported across studies, regions, and health systems. A better understanding of the characteristics of users and nonusers is critical to design solutions that are effectively integrated in patients' daily lives, and to ensure that these equitably reach out to different groups of patients, thus improving rather than entrenching health inequities. OBJECTIVE: This study aimed to evaluate the use of general health and fitness apps by patients with asthma and to identify determinants of usage. METHODS: A secondary analysis of the INSPIRERS observational studies was conducted using data from face-to-face visits. Patients with a diagnosis of asthma were included between November 2017 and August 2020. Individual-level data were collected, including age, gender, marital status, educational level, health status, presence of anxiety and depression, postcode, socioeconomic level, digital literacy, use of health services, and use of health and fitness apps. Multivariate logistic regression was used to model the probability of being a health and fitness app user. Statistical analysis was performed in R. RESULTS: A total of 526 patients attended a face-to-face visit in the 49 recruiting centers and 514 had complete data. Most participants were ≤40 years old (66.4%), had at least 10 years of education (57.4%), and were in the 3 higher quintiles of the socioeconomic deprivation index (70.1%). The majority reported an overall good health status (visual analogue scale [VAS] score>70 in 93.1%) and the prevalence of anxiety and depression was 34.3% and 11.9%, respectively. The proportion of participants who reported using health and fitness mobile apps was 41.1% (n=211). Multivariate models revealed that single individuals and those with more than 10 years of education are more likely to use health and fitness mobile apps (adjusted odds ratio [aOR] 2.22, 95%CI 1.05-4.75 and aOR 1.95, 95%CI 1.12-3.45, respectively). Higher digital literacy scores were also associated with higher odds of being a user of health and fitness apps, with participants in the second, third, and fourth quartiles reporting aORs of 6.74 (95%CI 2.90-17.40), 10.30 (95%CI 4.28-27.56), and 11.52 (95%CI 4.78-30.87), respectively. Participants with depression symptoms had lower odds of using health and fitness apps (aOR 0.32, 95%CI 0.12-0.83). CONCLUSIONS: A better understanding of the barriers and enhancers of app use among patients with lower education, lower digital literacy, or depressive symptoms is key to design tailored interventions to ensure a sustained and equitable use of these technologies. Future studies should also assess users' general health-seeking behavior and their interest and concerns specifically about digital tools. These factors may impact both initial engagement and sustained use.

Key factors associated with uncontrolled asthma - the Asthma Control in Latin America Study.

Objective: This study aimed to estimate asthma control at specialist treatment centers in four Latin American countries and assess factors influencing poor asthma control.Methods: Patients aged ≥12 years with an asthma diagnosis and asthma medication prescription, followed at outpatient specialist centers in Argentina, Chile, Colombia, and Mexico, were included. The study received all applicable ethical approvals. The Asthma Control Test (ACT) was used to classify patients as having controlled (ACT 20-25) or uncontrolled (ACT ≤19) asthma. Frequency and statistical tests were used to assess the association between hospital admissions/exacerbations/emergency department (ED) visits and uncontrolled asthma; multivariate logistic regression was used to assess the association of uncontrolled asthma with clinical/demographic variables.Results: A total of 594 patients were included. Overall controlled-asthma prevalence was 43.4% (95% confidence interval [CI]: 39.0, 47.4). Patients with uncontrolled asthma were more likely to be women (adjusted odds ratio [aOR]: 1.85; p = 0.003), non-white (aOR: 2.14; p < 0.001), obese (aOR: 1.71; p = 0.036), to have a low monthly family income (aOR: 1.75; p = 0.004), to have severe asthma (aOR:1.59; p = 0.26), and, compared with patients with controlled asthma, to have a higher likelihood of asthma exacerbations (34.5% vs. 15.9%; p < 0.001), hospital admissions (6.9% vs. 3.1%; p = 0.042), and ED visits (34.5% vs. 15.9%; p < 0.001) due to asthma.Conclusions: Even in specialist ambulatory services, fewer than half of patients were classified as having controlled asthma. The proportion of uncontrolled patients varied according to clinical and demographic variables.

Physiological response of Cistus salviifolius L. to high arsenic concentrations.

Arsenic is a trace element found in the environment which can be particularly toxic to living organisms. However, some plant species such as those of the genus Cistus are able to grow in soils with high As concentrations and could be used in the sustainable rehabilitation of mining areas through phytostabilization. In this work, the growth and the physiological response of Cistus salviifolius L. to As-induced oxidative stress at several concentrations (reaching 30 mg L-1) in an hydroponic system were evaluated for 30 days. Several growth parameters, chlorophyll content, chemical composition, one indicator of oxidative stress (H2O2) and two of the major antioxidative metabolites (ascorbate and glutathione) were analysed. The toxic effect of As was better perceived in the plants submitted to treatments with concentrations of 20 and 30 mg As L-1. Plants subjected to these treatments had higher concentration of As in roots and shoots. The concentrations of Ca, Mg, K and Fe in the plants as well as a large part of the evaluated growth parameters were also affected. Arsenic did not interfere with the ability of the plant to perform photosynthesis, as there were no significant differences in the contents of chlorophyll a, b and total between the different treatments. Plants from all treatments accumulated higher amount of As in roots than in shoots, and it was also in the roots that the concentrations of H2O2, AsA and GSH were higher. Cistus salviifolius showed high tolerance to As up to the concentration of 5 mg L-1, which makes it a species with high potential to be used in the phytostabilization of soils contaminated with As and presenting high concentrations of the element in the soil solution.

Asthma severity in four countries of Latin America.

BACKGROUND: In Latin America, there is scarce information about severe asthma (SA) according to the ERS/ATS 2014 criteria. This study aimed to compare the demographic, socio, clinical characteristics, treatment, and use of healthcare resources between SA and non-severe asthma (NSA) patients in Argentina, Colombia, Chile and Mexico. METHODS: A cross-sectional study was conducted including 594 asthma patients from outpatient specialized sites. A descriptive analysis was performed comparing SA patients and NSA. Chi-square and Mann Whitney tests were used to assess associations between asthma severity and outcome variables. RESULTS: Using ERS/ATS 2014 criteria, 31.0% of the patients were identified as SA. SA patients were older at diagnosis (mean age 31.64 years vs 24.71 years, p < 0.001) and had higher proportion of uncontrolled asthma than the NSA patients (64.1% vs 53.2%, p < 0.001). SA patients reported a significantly higher proportion of both hospital admission and emergency room (ER) visits due to asthma in the last year, compared with NSA patients, 8.7% vs. 3.7% (p = 0.011) and 37.0% vs. 21.7% (p < 0.001), respectively. CONCLUSIONS: SA patients were older, had greater proportions in some comorbidities and experienced increased healthcare utilization. Also, our results showed that even in patients using the last steps of treatment (GINA step 4 or 5), there was still a higher proportion of uncontrolled disease.

Use of chitosan coating in increasing the shelf life of liquid smoked Nile tilapia (Oreochromis niloticus) fillet.

The aim of this research was to evaluate the efficiency of liquid smoking and chitosan coating on the shelf life of Nile tilapia (Oreochromis niloticus) fillets. Fillets without liquid smoked and chitosan coating (control), liquid smoked fillets (LS), and liquid smoked and chitosan coated fillets (LSCh) were stored at 4 ± 1 °C for 30 days. The physicochemical (pH, moisture content, water activity-aw, color, texture, total volatile bases nitrogen-TVB-N and thiobarbituric acid reactive substances-TBARS) and microbiological analyses (mesophilic and psychrotrophic counts) and the electrophoresis profile of samples were carried out. Physicochemical parameters, such as TVB-N and TBARS, were reduced in the tilapia fillets with liquid smoking. The presence of the coating of chitosan was effective for the control of the microorganisms during storage. This work showed that the addition of a chitosan coating in liquid-smoked fillets further enhanced the effect of preservation.

Efficacy and safety of induction chemotherapy in oral cavity cancer: An eight-year experience at a Portuguese reference center.

BACKGROUND: Induction chemotherapy has been described as an option in locally advanced oral cavity squamous cell carcinoma when the surgical morbidity is expected to be high. This work aimed to evaluate the outcome and safety of induction chemotherapy in this setting. METHODS: We performed a retrospective and observational study including patients with oral cavity squamous cell carcinoma, treated with induction chemotherapy between January 2010 and December 2018. Outcomes included induction chemotherapy toxicity, treatment response, disease-free survival and overall survival. RESULTS: A total of 108 oral cavity squamous cell carcinoma patients were included. Ninety-six (88.9%) had stage IV disease, while 12 (11.1%) had stage III. Eighty-four patients (80.8%) achieved at least a partial response to induction chemotherapy at clinical evaluation, and 75 (72.1%) at radiological evaluation. Seventy-eight patients have been proposed for subsequent definitive treatments, with no differences obtained in prognosis, when comparing surgical to non-surgical approaches. In patients treated with definitive treatments, improved five-year disease-free survival was obtained if at least a clinical (56.3%; p=0.001) or radiological (52.9%; p=0.001) partial response was achieved after induction chemotherapy. Similarly, superior five-year overall survival was verified for those achieving at least clinical (51.1%; p<0.0001) or radiological (52.6%; p=0.001) partial response. Also, accomplishing a pathologic complete response (n=22.6%) significantly improved disease-free survival (p=0.039) and overall survival (p=0.005). Grade 3 and 4 toxicities were observed in 52 patients (41.8%). CONCLUSION: Responses to induction chemotherapy predicted prognosis in our population, however important toxicities were observed. Further studies are necessary to identify induction chemotherapy response predictors and subgroups who may benefit from this approach.

A New Era in Salivary Gland Carcinoma Treatment: A Case Report.

Salivary gland cancers are rare and heterogenous malignancies which makes it hard to standardize treatments with good evidence levels. The localized disease approach is well established, with surgery to the primary site and adjuvant radiation therapy in patients with high-risk features. Treatment of advanced disease should be multidisciplinary. Local approaches, which include radiation therapy, surgery, and thermoablation, among others, have the potential to achieve durable disease control with low toxicity. Chemotherapy has shown disappointing results, so systemic treatment should be guided by actionable genetic alterations, which in salivary gland cancers rely on the histologic type. When directed molecular tests are not useful, a multigene panel should be performed. This case is a good example of how to integrate all these possible tretaments in clinical practice, including molecular testing and target treatment.

Pertuzumab in Combination with Trastuzumab and Docetaxel in the Neoadjuvant Treatment for HER2-Positive Breast Cancer.

Introduction: This study aims to assess safety and effectiveness of pertuzumab in combination with trastuzumab and docetaxel in the neoadjuvant treatment (NeoT) of HER2-positive breast cancer. Methods: Two consecutive retrospective cohorts (n = 94, 2012-2015 and 2015-2017) of adult women with HER2-positive breast cancer, receiving NeoT at the breast clinic in Portugal (IPO-Porto), were followed. All patients had surgery and received trastuzumab as adjuvant therapy. The 2012-2015 cohort received doxorubicin, cyclophosphamide, docetaxel plus trastuzumab, whereas the 2015-2017 cohort was treated with the same protocol plus pertuzumab. Results: The 2012-2015 cohort was older (median 53 years), with locally advanced tumors (48.1%), mostly hormone receptor positive (59.3%). The 2015-2017 cohort was younger (median 43 years) with 60% operable tumors. Pathologic complete response (pCR) improved in the second cohort, while maintaining a good safety profile and tolerability. Clinical staging (p = 0.001) and hormone receptor (p = 0.003) were significant predictors of pCR, but not treatment regimen (p = 0.304). Conclusion: Further research with larger samples and longer follow-up is needed to understand the clinical differences. Clinical effectiveness of treatment should also be measured through overall and progression-free survival.

Health outcomes and budget impact projection of anti-PD-(L)1s in cancer care in Portugal.

Introduction: PD-[L]1 inhibitors revolutionized cancer treatment but challenge the affordability of health systems. This policy-focused model aimed to estimate the health and budget impact of anti-PD-(L)1s in Portugal and inform current discussions. Materials and methods: The Health Impact Projection (HIP) model estimates clinical (life years, progression-free survival [PFS] years, and quality-adjusted life years [QALY] gained and adverse events [AEs] incurred) and economic (direct and indirect costs) outcomes in a world where cancer patients are initiating treatment with standard-of-care (SOC) versus SOC plus anti-PD-(L)1s over a 3-year time horizon. Indications included adjuvant and metastatic melanoma, non-small cell lung cancer (first and second line), metastatic triple-negative breast cancer, head and neck cancer, urothelial carcinoma, and renal cell carcinoma. Model inputs were based on publicly available literature data and expert opinion. Results: The model estimated that, over 3 years, 7,773 patients would be treated with anti-PD-(L)1s, realizing a gain of 4,787 life years, 6,901 PFS years, and 4,214 QALYs and avoiding 399 AEs. The introduction of anti-PD-(L)1s had a projected average annual impact of ≈ €108 million and a share of 20% of total cancer medicines expenditure and 0.6% of total healthcare expenditure in 2021. Although higher disease management costs are expected for patients living longer with anti-PD-(L)1s and drug acquisition costs are considerable, that is partially offset by a reduction in end-of-life costs (€611,092/year) and costs associated with patient productivity lost to cancer (€9,128,142/year). Discussion: This model highlights the significant survival and QoL benefit of anti-PD-(L)1s for cancer patients in Portugal, with a relatively low increased cost in total healthcare expenditure.

Portuguese consensus on the prevention and treatment of nausea and vomiting induced by cancer treatments.

Chemotherapy-induced nausea and vomiting (CINV) and radiotherapy-induced nausea and vomiting (RINV) strongly affect the quality of life of patients with cancer. Inadequate antiemetic control leads to the decline of patients' quality of life, increases rescue interventions, and may even compromise adherence to cancer treatment. Although there are international recommendations for controlling CINV and RINV, these recommendations focus mainly on pharmacological management, with scarce information on additional measures that patients may adopt. Moreover, the prophylaxis and management of CINV/RINV are not always applied. Thus, we identified the need to systematize the strategies for preventing and managing CINV/RINV and the associated risk factors to implement and promote effective prophylactic antiemetic regimens therapy in patients with cancer. This review sought to create a set of practical recommendations for managing and controlling CINV/RINV, according to the current international recommendations for antiemetic therapy and the main risk factors. Conclusively, we intended to produce a patient-centered guidance document for health care professionals focused on the awareness, monitoring, and treatment of CINV/RINV.

Symptoms of anxiety and depression in patients with persistent asthma: a cross-sectional analysis of the INSPIRERS studies.

OBJECTIVES: Anxiety and depression are relevant comorbidities in asthma, but, in Portugal and Spain, data on this topic are scarce. We assessed, in patients with asthma, the frequency of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) and the European Quality of Life Five Dimension Questionnaire (EQ-5D); the level of agreement between these questionnaires, and the factors associated with these symptoms. METHODS: This is a secondary analysis of the INSPIRERS studies. A total of 614 adolescents and adults with persistent asthma (32.6±16.9 years, 64.7% female) were recruited from 30 primary care centres and 32 allergy, pulmonology and paediatric clinics. Demographic and clinical characteristics, HADS and EQ-5D were collected. A score ≥8 on Hospital Anxiety and Depression Scale-Anxiety/Hospital Anxiety and Depression Scale-Depression or a positive answer to EQ-5D item 5 indicated the presence of these symptoms. Agreement was determined by Cohen's kappa. Two multivariable logistic regressions were built. RESULTS: According to HADS, 36% of the participants had symptoms of anxiety and 12% of depression. According to EQ-5D, 36% of the participants had anxiety/depression. The agreement between questionnaires in identifying anxiety/depression was moderate (k=0.55, 95% CI 0.48 to 0.62). Late asthma diagnosis, comorbidities and female gender were predictors of anxiety/depression, while better asthma control, health-related quality of life and perception of health were associated with lower odds for anxiety/depression. CONCLUSION: At least 1/3 of the patients with persistent asthma experience symptoms of anxiety/depression, showing the relevance of screening these disorders in patients with asthma. EQ-5D and HADS questionnaires showed a moderate agreement in the identification of anxiety/depression symptoms. The identified associated factors need to be further investigated in long-term studies.

Systemic treatment for hormone receptor-positive/HER2-negative advanced/metastatic breast cancer: A review of European real-world evidence studies.

This review examined patterns of systemic anticancer treatment in patients with HR+ /HER2- metastatic breast cancer in real-world clinical practice in Europe since 2016 to assess whether they reflect clinical guidelines and recent changes in available treatment options. We identified 30 publications for inclusion. In studies evaluating patients up to the end of 2017, endocrine therapy predominated, with endocrine monotherapy typically used in 45-65 % of patients. More recent studies suggested that use of cyclin-dependent kinase 4/6 inhibitor therapy has gained ground since European approval in late 2016, with two studies reporting first-line use in over 55 % of patients. Chemotherapy was typically used first line in 25-45 % of patients, although current guidelines recommend endocrine therapy in the absence of a visceral crisis. In conclusion, our review suggests that the most recent treatment developments for patients with HR+ /HER2 - metastatic breast cancer are being reflected in the changing treatment patterns seen in real-world practice.

Genetic Polymorphisms as Predictors of Survival in Breast Cancer: Future Lessons in Historical Data.

Introduction Breast cancer is the most common cancer among women worldwide and one of the main causes of death in the female sex. Genetic polymorphisms in the mu-opioid receptor (OPRM1) and catechol-o-methyltransferase (COMT) genes have been shown to increase breast cancer risk. Variants in these genes may carry a prognostic impact in breast cancer. Long follow-up intervals are critical to adequately analyze prognosis in diseases with prolonged survival times and late relapses. Objective To analyze the impact of genetic polymorphisms on the survival of a cohort of breast cancer patients with very long follow-up. Methods This was a retrospective study of patients treated at Portuguese Oncology Institute of Porto (IPO Porto), a Portuguese comprehensive cancer center, with invasive carcinoma of the breast with very long follow-up, with analysis of genetic polymorphisms OPMR1 rs1799971 (AA vs. G allele) and COMT rs4680 (CC vs T allele) on biological samples. Statistical analysis of survival was performed using the Kaplan-Meier method, log-rank test, and Cox regression method. Results A total of 143 patients with invasive breast cancer were included, with a median follow-up of 21.5 years. There was a statistically significant difference in overall survival (OS) at 30 years according to the OPMR1 polymorphism, with lower survival in patients with the AA genotype (p<0.05). The difference in OS according to the COMT polymorphism was also statistically significant, with worse survival in patients with genotype T allele (p<0.05). The genetic variants were not associated with patient age, stage at diagnosis, or tumor grade. Discussion The genetic polymorphisms of OPRM1 and COMT affected the overall survival of breast cancer patients, in concordance with previous research. Further investigation is needed in order to clarify the prognostic impact of these genetic alterations on breast cancer.

Social Media Listening to Understand the Lived Experience of Individuals in Europe With Metastatic Breast Cancer: A Systematic Search and Content Analysis Study.

Background: Despite a wealth of real-world data on metastatic breast cancer (mBC), insights into the lived experience are lacking. This study aimed to explore how the lived experience of mBC is described on social media. Methods: A predefined search string identified posts relevant to the lived experience of mBC from Twitter, patient forums, and blogs across 14 European countries. The final data set was analyzed using content analysis. Results: A total of 76,456 conversations were identified between November 1, 2018, and November 30, 2020. Twitter was the most commonly used social media platform across all 76,456 conversations from the raw data set (n = 61,165; 80%). Automated and manual relevancy checks followed by a final random sampling filter identified 820 conversations for content analysis. The majority of data from the raw data set was generated from the United Kingdom (n = 31,346; 41%). From this final data set, 61% of posts were authored by patients, 15% by friends and/or family members of patients, and 14% by caregivers. A total of 686 conversations described the patient journey (n = 686/820; 84%); 64% of these (n = 439) concerned breast cancer treatment, with approximately 40% of discussions regarding diagnosis and tests (n = 274/686) and less than 20% of discussions surrounding disease management (n = 123/686; 18%). Key themes relating to a lack of effective treatment, prolonged survival and associated quality of life, debilitating consequences of side effects, and the social impacts of living with mBC were identified. Conclusions: The findings from this study provided an insight into the lived experience of mBC. While retrospective data collection inherently limits the amount of demographic or clinical information that can be obtained from the population sample, social media listening studies offer training to healthcare professionals in communication, the importance of quality of life, organization of healthcare, and even the design of clinical trials. As new targeted therapies are gradually incorporated into clinical practice, innovative technologies, such as social media listening, have the potential to support regulatory procedures and drug toxicity monitoring, as well as provide the patient voice in the regulation of new and existing medicines.

Bevacizumab in the treatment of metastatic breast cancer: three case reports.

Case reports are presented for three patients with metastatic breast cancer who received first-line treatment with bevacizumab in combination with taxanes in clinical trials. Two patients showed peak reductions in lesion size of 49 and 70%, respectively. In one patient, subsequent treatment with bevacizumab in combination with capecitabine [Xeloda (after discontinuation of paclitaxel due to asthenia)] yielded peak reductions in target lesion size of 78%. One patient experienced a progression-free survival time of 16 months. In all three patients, bevacizumab was well tolerated and mostly displayed only mild toxicities.

The addition of neoadjuvant pertuzumab for the treatment of HER2+ breast cancer: a cost estimate with real-world data.

BACKGROUND: Breast cancer (BC) is largely prevalent worldwide. HER2-positive BC account for roughly 20-25% of all BC cases and has an overall survival lower than other BC. Innovation on BC therapeutics is a constant, but novel therapies have higher costs. Therefore, cost-effectiveness research is essential to provide healthcare decision-makers with solid foundations for a resource allocation. This study aims to estimate the average direct medical costs/patient and cost-effectiveness of adding pertuzumab in neoadjuvant treatment (NeoT) for HER2-positive breast cancer (BC). METHODS: Two retrospective real-world consecutive cohorts of ≥18yo female patients diagnosed with HER2-positive BC treated with NeoT at the Breast Clinic of IPO-Porto were studied. The AC-DH regimen (2012-2015) comprised 8 cycles of neoadjuvant therapy (4 cycles of doxorubicin + cyclosphosphamide followed by 4 cycles ofdocetaxel + trastuzumab), while the AC-DHP regimen (2015-2017) included also pertuzumab as NeoT. NeoT was followed by surgery and adjuvant trastuzumab. Micro-costing technique and a bottom-up approach was used comprising all medical direct costs from the hospital perspective. Unit costs were obtained from government official prices or from IPO-Porto costing system. Costs were adjusted to 2017 and are expressed in euros. Multivariable logistic regression models were used for effectiveness assessment, while generalized linear models with gamma distribution were used for costs. ICER was calculated using the pathological complete response (pCR) as the preferential measure of effectiveness. Sensitivity analysis was also performed. RESULTS: AC-DHP (n = 40) and AC-DH (n = 54) cohorts had heterogenous patient profiles (median age 43y/53y; 67.5%/59.3% positive HR; 60.0%/27.8% operable; 25.0%/24.1% inflammatory, respectively). The AC-DHP average total cost/patient was 56,375€, with pertuzumab accounting for 13,978€ (24.79%) and increasing in 15,982€ the average cost/patient (p < 0.001). Clinical staging and hormone receptors (HR) were significantly associated with pCR. ICER was 1.370€ per percentage point of pCR. CONCLUSIONS: ICER was more favourable in stage III HR negative BC patients compared to other patient profiles. Innovative treatments access is critical to deliver high-quality healthcare, but sustainability must be considered. These results suggest the importance of establishing a cost-effectiveness profile of Pertuzumab in NeoT for HER2-positive BC.

Antioxidant activity and chemical composition of meat from broilers fed diets containing different essential oils.

BACKGROUND AND AIM: Broiler meat is susceptible to lipid oxidation due to its high content of unsaturated fatty acids, especially when stored for a long time. Concerning with that problem, we can add natural compounds to the animal feed, as the plant essential oils, which have antioxidant, antimicrobial, and antifungal activities. The objective of this study was to evaluate the antioxidant activity, fatty acid profile, and chemical composition of the meat of broilers fed with diets containing different essential oil, including lemongrass (Cymbopogon flexuosus) and pedestrian tea (Lippia aff. rotundifolia). MATERIALS AND METHODS: The experimental design used was a 4×4 factorial scheme (storage time×diets), and each treatment was repeated thrice. The treatments were applied as negative control (without antimicrobial); positive control (ration supplemented with 10 ppm of enramycin and 42 ppm of salinomycin), lemongrass (ration with 120 mg of essential oil of lemongrass for each kilogram of live weight of the animals), and pedestrian tea (ration with 120 mg of essential oil of pedestrian tea for each kilogram of live weight of the animals). Storage was performed after slaughter and evaluated monthly for 4 months. RESULTS: The inclusion of lemongrass oil and pedestrian tea in the broiler diet did not change the ether extract content of the meat sample obtained from thigh and drumstick. The storage time promotes an increase in the moisture loss of the meat from the 2nd month in all treatments. There was an interaction between the additive and storage time for moisture loss. In the 2nd month of storage, the meat from broilers fed the antibiotic-containing feed had a lower moisture loss than those from broilers in the other treatment groups. The fatty acid profile did not differ statistically between the different treatment groups. The inclusion of additives in the food dropped the lipid oxidation at the 2nd month of storage. From the 3rd month, however, only the essential oils showed antioxidant effect. CONCLUSION: Antioxidant activity was positive for treatments that included essential oils. The lemongrass oil and pedestrian tea can be used as antioxidant additives in broiler diets to improve the oxidative stability of thigh-drumstick meat during storage. The results of the study suggest a good prospective for further research with profitability of usage essentials oils examined, for their economical application as feed components in broiler nutrition.

Oral Angiotensin-(1-7) Peptide Modulates Intestinal Microbiota Improving Metabolic Profile in Obese Mice.

BACKGROUND: Obesity is a serious health problem that dysregulate Renin-Angiotensin System (RAS) and intestinal microbiota. OBJECTIVE: The present study aimed to evaluate the Angiotensin-(1-7) [ANG-(1-7)] oral formulation effects on obese mice intestinal microbiota. METHODS: Mice were divided into four groups: obese and non-obese treated with ANG-(1-7) and obese and non-obese without ANG-(1-7) during four weeks. RESULTS: We observed a significant decrease in the fasting plasma glucose, total cholesterol, triglycerides, and Low-density lipoprotein levels and increased High-density lipoprotein in animals treated with ANG-(1-7). The histological analysis showed intestinal villi height reduction in mice treated with ANG-(1-7). Additionally, increased Bacteroidetes and decreased Firmicutes (increased Bacteroidetes/ Firmicutes ratio) and Enterobacter cloacae populations were observed in the High-Fat Diet + ANG-(1-7) group. Receptor toll-like 4 (TLR4) intestinal mRNA expression was reduced in the HFD+ANG-(1-7) group. Finally, the intestinal expression of the neutral amino acid transporter (B0AT1) was increased in animals treated with ANG-(1-7), indicating a possible mechanism associated with tryptophan uptake. CONCLUSION: The results of the present study suggest for the first time an interaction between oral ANG-(1-7) and intestinal microbiota modulation.
