Leveraging the Country-of-Origin Image by managing it at different levels

The study aims to articulate the Country-of-Origin Image (COI) at different levels (country, industry and firm levels) by advancing the knowledge and exploring ways to manage the COI at different levels underpinned on corporate brand and brand architecture strategies. For that, a mixed-methods approach was conducted where a qualitative study—looking into the case of the Brazilian Machinery Solutions Programme (BMS)—was carried out in combination with a quantitative survey held with a specific target country (Colombia). Data for the quantitative study were collected with 89 Colombian industrial buyers using Brazil as a manufacturer-supplier and country of reference. Findings indicate the relevance of managing the COI at different levels and highlight the development of the COI at the industry level. This demonstrates that nation-branding and COI literature should be developed and articulated using strategic marketing programmes and brand architecture elements. The study advances the body of knowledge in the COI literature by analysing it within three different levels and offers a framework to manage the COI using corporate brand and brand architecture elements, which is beneficial to institutions, governments, trade agencies, industry associations and firms to leverage the COI by understanding aspects of it transferrable to industry and firm levels

Measles-containing vaccines in Brazil: Coverage, homogeneity of coverage and associations with contextual factors at municipal level

We aimed to (i) describe both the coverage and the homogeneity of coverage of the first and second doses of measles-containing vaccines (MCV) in Brazil in 2017, and (ii) to investigate the potential influence of contextual factors at municipal level. All 5570 Brazilian municipalities were included. The North and Center-West regions presented the lowest coverages of the first and second doses of MCV, respectively. We found significant associations of both first and second doses of MCV with population size, coverage of Family Health Strategy (FHS) and other indicators of living conditions and inequalities. Monitoring the homogeneity of MCV coverage at national, regional and state levels is essential, as it allows identifying areas at higher risk of measles spread that should be targeted for vaccination. Targeting large cities i.e. 100,000 or more inhabitants, especially poor neighborhoods and areas with low FHS coverage, could lead to improvements in coverage homogeneity

Changes in antidepressant use in Australia: A nationwide analysis (2015–2021)

Background: Depression and anxiety affect 4–14% of Australians every year; symptoms may have been exacerbated during the COVID-19 pandemic. We examined recent patterns of antidepressant use in Australia in the period 2015–2021, which includes the first year of the pandemic. Methods: We used national dispensing claims for people aged ⩾10 years to investigate annual trends in prevalent and new antidepressant use (no antidepressants dispensed in the year prior). We conducted stratified analyses by sex, age group and antidepressant class. We report outcomes from 2015 to 2019 and used time series analysis to quantify changes during the first year of the COVID-19 pandemic (March 2020–February 2021). Results: In 2019, the annual prevalence of antidepressant use was 170.4 per 1000 women and 101.8 per 1000 men, an increase of 7.0% and 9.2% from 2015, respectively. New antidepressant use also increased for both sexes (3.0% for women and 4.9% for men) and across most age groups, particularly among adolescents (aged 10–17 years; 46–57%). During the first year of the COVID-19 pandemic, we observed higher than expected prevalent use (+2.2%, 95% CI = [0.3%, 4.2%]) among females, corresponding to a predicted excess of 45,217 (95% CI = [5,819, 84,614]) females dispensed antidepressants. The largest increases during the first year of the pandemic occurred among female adolescents for both prevalent (+11.7%, 95% CI = [4.1%, 20.5%]) and new antidepressant use (+15.6%, 95% CI = [8.5%, 23.7%]). Conclusion: Antidepressant use continues to increase in Australia overall and especially among young people. We found a differential impact of the COVID-19 pandemic in treated depression and anxiety, greater among females than males, and greater among young females than other age groups, suggesting an increased mental health burden in populations already on a trajectory of increased use of antidepressants prior to the pandemic. Reasons for these differences require further investigation

Brazilian gamma detection device for sentinel lymph node biopsy

OBJECTIVE: To test the effectiveness of an intra-operative gamma detection Brazilian device (IPEN) on sentinel lymph node biopsy (SLNB) procedures. METHODS: Forty melanoma or breast cancer patients with indication for undergoing SLNB were studied. Lymphoscintigraphy was done 2 to 24 hours prior to surgery. Lymphatic mapping with vital dye and gamma detection were performed intraoperatively. For gamma detection Neoprobe ® 1500 was used followed by IPEN (equipment under test) in the first 20 patients and for the remaining half IPEN was used first to verify its ability to locate the sentinel node (SN). Measurements were taken from the radiopharmaceutical product injection site, from SN (in vivo and ex vivo) and from background. It was recorded if the SN was stained or not and if it was found easily by surgeon. RESULTS: There were 33 (82.5%) breast cancer and 7 (17.5%) melanoma patients. Ages varied from 21 to 68 year-old (median age of 46). Sex distribution was 35 (87.5%) women and 5 (12.5%) men. Sentinel node was found in all but one patient. There was no statistical difference between the reasons ex vivo/ background obtained with the measures of both equipments (p=0, 2583-ns). The SN was easily found by the surgeon with both devices. CONCLUSION: The SLNB was successfully performed using either equipment. It was possible to do SLNB with the Brazilian device developed by IPEN without prejudice for the patient.OBJETIVO: Testar a eficácia de equipamento de detecção gama intra-operatória (DGI) desenvolvido pelo IPEN (Brasil), em procedimentos de biópsia de linfonodo sentinela (BLS) no melanoma e no câncer de mama. MÉTODOS: Foram estudados 40 pacientes portadores de melanoma ou câncer de mama com indicação para realização de BLS.Todos pacientes foram submetidos à linfocintilografia e a BLS ocorreu entre 2 a 24 horas após a mesma. Concomitantemente à DGI, realizou-se o mapeamento linfático com corante vital. Foram feitas leituras com o equipamento convencional Neoprobe® 1500 e com o equipamento em teste (IPEN) dos valores de captação do sítio de injeção do radiofármaco, do LS in vivo e ex vivo e da captação de fundo. Foi registrado se o LS estava corado e se o cirurgião teve facilidade para encontrá-lo. Nos primeiros 20 pacientes utilizou-se o equipamento convencional e depois o de teste; nos outros 20, utilizou-se primeiro o equipamento em teste, com objetivo de verificar se o mesmo identificava primariamente o LS. RESULTADOS: Dos quarenta pacientes, 33 eram portadores de tumor de mama e sete de melanoma cutâneo; variação da idade: 21 a 68 anos (mediana= 46 anos); 35 mulheres e 5 homens. Em apenas um paciente o LS não foi encontrado, nem pela DGI nem pelo corante vital. Não houve diferença estatística entre as razões ex vivo/fundo obtidas com os dois equipamentos (p=0, 2583-ns). CONCLUSÃO: É possível realizar o procedimento de BLS com o equipamento brasileiro desenvolvido pelo IPEN, com facilidade e sem prejuízo para o paciente.Hospital Israelita Albert EinsteinIPENUniversidade Federal de São Paulo (UNIFESP)Faculdade de Medicina Anhembi-MorumbiUNIFESPSciEL

Physicochemical-guided design of cathelicidin-derived peptides generates membrane active variants with therapeutic potential.

The spread of multi-drug resistance and the slow pace at which antibiotics come onto the market are undermining our ability to treat human infections, leading to high mortality rates. Aiming to overcome this global crisis, antimicrobial peptides are considered promising alternatives to counter bacterial infections with multi-drug resistant bacteria. The cathelicidins comprise a well-studied class of AMPs whose members have been used as model molecules for sequence modifications, aiming at enhanced biological activities and stability, along with reduced toxic effects on mammalian cells. Here, we describe the antimicrobial activities, modes of action and structural characterization of two novel cathelicidin-like peptides, named BotrAMP14 and CrotAMP14, which were re-designed from snake batroxicidin and crotalicidin, respectively. BotrAMP14 and CrotAMP14 showed broad-spectrum antibacterial activity against susceptible microorganisms and clinical isolates with minimal inhibitory concentrations ranging from 2-35.1 μM. Moreover, both peptides had low cytotoxicity against Caco-2 cells in vitro. In addition, in vivo toxicity against Galleria mellonella moth larvae revealed that both peptides led to>76% larval survival after 144 h. Microscopy studies suggest that BotrAMP14 and CrotAMP14 destabilize E. coli membranes. Furthermore, circular dichroism and molecular dynamics simulations indicate that, in a membrane-like environment, both peptides adopt α-helical structures that interact with bilayer phospholipids through hydrogen bonds and electrostatic interaction. Thus, we concluded that BotrAMP14 and CrotAMP14 are helical membrane active peptides, with similar antibacterial properties but lower cytotoxicity than the larger parent peptides batroxicidin and crotalicidin, having advantages for drug development strategies

Sociodemographic characteristics determine dietary pattern adherence during pregnancy

OBJECTIVE:Sociodemographic factors may affect adherence to specific dietary patterns during pregnancy. The present study aimed to identify dietary patterns during pregnancy and associated factors among Brazilian pregnant women. DESIGN:A cross-sectional analysis. Dietary intake was evaluated with a semi-quantitative FFQ during the first postpartum week; the time frame included the second and third gestational trimesters. Principal component analysis was used to identify dietary patterns during pregnancy. Sociodemographic data were obtained using a structured questionnaire. Multiple linear regressions were applied to test the associations between the sociodemographic factors and dietary patterns. SETTING:Mesquita, Rio de Janeiro, Brazil, 2011. SUBJECTS:Postpartum women (n 327) who were 18-45 years of age and Mesquita residents. RESULTS:Three different dietary patterns were identified: 'healthy' (mainly comprising legumes, vegetables and fruits), 'mixed' (mainly comprising candy, butter and margarine, and snacks) and 'traditional' (mainly comprising beans and rice). Women with a higher monthly per capita family income (β=0·0006; 95% CI 0·0001, 0·001; P=0·011) and women of older age (β=0·021; 95% CI -0·001, 0·042; P=0·058) were more likely to adhere to the 'healthy' dietary pattern. Women with higher parity were less likely to adhere to the 'healthy' pattern (β=-0·097; 95% CI -0·184, -0·009; P=0·030) and were more likely to adhere to the 'traditional' pattern (β=0·098; 95% CI 0·021, 0·175; P=0·012). Although not statistically significant, older women were less likely to adhere to the 'mixed' (β=-0·017; 95% CI -0·037, 0·003; P=0·075) and 'traditional' (β=-0·018; 95% CI -0·037, 0·001; P=0·061) dietary patterns. CONCLUSIONS:Monthly per capita family income, parity and maternal age were factors associated with adherence to a healthy diet during pregnancy
