The respiratory oxygenation index for identifying the risk of orotracheal intubation in COVID-19 patients receiving high-flow nasal cannula oxygen.

OBJECTIVE: To assess whether the respiratory oxygenation index (ROX index) measured after the start of high-flow nasal cannula oxygen therapy can help identify the need for intubation in patients with acute respiratory failure due to coronavirus disease 2019. METHODS: This retrospective, observational, multicenter study was conducted at the intensive care units of six Brazilian hospitals from March to December 2020. The primary outcome was the need for intubation up to 7 days after starting the high-flow nasal cannula. RESULTS: A total of 444 patients were included in the study, and 261 (58.7%) were subjected to intubation. An analysis of the area under the receiver operating characteristic curve (AUROC) showed that the ability to discriminate between successful and failed high-flow nasal cannula oxygen therapy within 7 days was greater for the ROX index measured at 24 hours (AUROC 0.80; 95%CI 0.76 - 0.84). The median interval between high-flow nasal cannula initiation and intubation was 24 hours (24 - 72), and the most accurate predictor of intubation obtained before 24 hours was the ROX index measured at 12 hours (AUROC 0.75; 95%CI 0.70 - 0.79). Kaplan-Meier curves revealed a greater probability of intubation within 7 days in patients with a ROX index ≤ 5.54 at 12 hours (hazard ratio 3.07; 95%CI 2.24 - 4.20) and ≤ 5.96 at 24 hours (hazard ratio 5.15; 95%CI 3.65 - 7.27). CONCLUSION: The ROX index can aid in the early identification of patients with acute respiratory failure due to COVID-19 who will progress to the failure of high-flow nasal cannula supportive therapy and the need for intubation.

Porphyrin Atropisomerism as a Molecular Engineering Tool in Medicinal Chemistry, Molecular Recognition, Supramolecular Assembly, and Catalysis.

Porphyrin atropisomerism, which arises from restricted σ-bond rotation between the macrocycle and a sufficiently bulky substituent, was identified in 1969 by Gottwald and Ullman in 5,10,15,20-tetrakis(o-hydroxyphenyl)porphyrins. Henceforth, an entirely new field has emerged utilizing this transformative tool. This review strives to explain the consequences of atropisomerism in porphyrins, the methods which have been developed for their separation and analysis and present the diverse array of applications. Porphyrins alone possess intriguing properties and a structure which can be easily decorated and molded for a specific function. Therefore, atropisomerism serves as a transformative tool, making it possible to obtain even a specific molecular shape. Atropisomerism has been thoroughly exploited in catalysis and molecular recognition yet presents both challenges and opportunities in medicinal chemistry.

The Impact of Motherhood on Women's Career Progression: A Scoping Review of Evidence-Based Interventions.

(1) Background: Despite the progress made by women in the workplace, mothers still face systemic barriers that prevent them from advancing professionally. This "motherhood penalty" involves a variety of discriminatory practices and experiences that mothers can face at work, including being held to stricter standards regarding salary and recruitment. Despite ongoing research on the association between motherhood and career outcomes, few studies specifically explore how motherhood impacts career advancement and, consequently, access to leadership. This scoping review seeks to gain an understanding of how motherhood impacts women's career progression, and how interventions can address the underrepresentation of mothers in leadership. (2) Methods: Following the PRISMA-ScR framework, we analyzed 52 articles from 2010 to 2022, drawn from 10 databases. (3) Results: The results showed both negative and positive impacts of motherhood on career progression, affecting mothers' attitudes, feelings, and behaviors and yielding changes in interpersonal relationships and work conditions. Intersectionality is highlighted, urging a nuanced examination of challenges faced by mothers from a diversity of backgrounds. Recommendations for interventions include individual and institutional efforts, comprising societal support structures, organizational policy changes, and cultural shifts. (4) Conclusions: This scoping review offers an updated perspective on a classic challenge, providing practical insights for a more inclusive and structural understanding of the career trajectories of working mothers.

Antitumor Immunity Mediated by Photodynamic Therapy Using Injectable Chitosan Hydrogels for Intratumoral and Sustained Drug Delivery.

Photodynamic therapy (PDT) is an anticancer therapy with proven efficacy; however, its application is often limited by prolonged skin photosensitivity and solubility issues associated with the phototherapeutic agents. Injectable hydrogels which can effectively provide intratumoral delivery of photosensitizers with sustained release are attracting increased interest for photodynamic cancer therapies. However, most of the hydrogels for PDT applications are based on systems with high complexity, and often, preclinical validation is not provided. Herein, we provide a simple and reliable pH-sensitive hydrogel formulation that presents appropriate rheological properties for intratumoral injection. For this, Temoporfin (m-THPC), which is one of the most potent clinical photosensitizers, was chemically modified to introduce functional groups that act as cross-linkers in the formation of chitosan-based hydrogels. The introduction of -COOH groups resulted in a water-soluble derivative, named PS2, that was the most promising candidate. Although PS2 was not internalized by the target cells, its extracellular activation caused effective damage to the cancer cells, which was likely mediated by lipid peroxidation. The injection of the hydrogel containing PS2 in the tumors was monitored by high-frequency ultrasounds and in vivo fluorescence imaging which confirmed the sustained release of PS2 for at least 72 h. Following local administration, light exposure was conducted one (single irradiation protocol) or three (multiple irradiation protocols) times. The latter delivered the best therapeutic outcomes, which included complete tumor regression and systemic anticancer immune responses. Immunological memory was induced as ∼75% of the mice cured with our strategy rejected a second rechallenge with live cancer cells. Additionally, the failure of PDT to treat immunocompromised mice bearing tumors reinforces the relevance of the host immune system. Finally, our strategy promotes anticancer immune responses that lead to the abscopal protection against distant metastases.

Quality of systematic reviews on the treatment of vesiculobullous skin diseases. A meta-epidemiological study.

BACKGROUND: Systematic reviews of Randomized Controlled Trials (RCTs) are considered high-level evidence to support a decision on therapeutic interventions, and their methodological quality is essential to provide reliable and applicable results. OBJECTIVE: This meta-epidemiological study aimed to map and critically appraise systematic reviews assessing treatments for vesiculobullous skin diseases. METHODS: We conducted a comprehensive search strategy on MEDLINE (via Pubmed) in December 2022 without restrictions to find systematic reviews evaluating pharmacological interventions for vesiculobullous skin diseases. The methodological quality was assessed using the AMSTAR-2 tool, and additional information was extracted. We identified nine systematic reviews published between 2002 and 2021, seven assessing pemphigus. RESULTS: According to the AMSTAR-2 tool, 55.6% were classified as critically low quality, 22.2% as moderate quality, 11.1% as low and 11.1% as high quality. No review assessed the certainty of the evidence (GRADE); 86% of pemphigus reviews had at least two overlapping RCTs. There were some limitations regarding methodological flaws and the AMSTAR-2 tool use CONCLUSIONS: These findings reveal a frail methodological quality of systematic reviews about vesiculobullous diseases treatment that may impact the results. Therefore, methodological rigor is mandatory for future systematic reviews to avoid duplication of effort and increase the certainty of the evidence supporting decision-making.

The influence of tonality, tempo, and musical sophistication on the listener's time-duration estimates.

Music listening affects time perception, with previous studies suggesting that a variety of factors may influence this: musical, individual, and environmental. Two experiments investigated the effect of musical factors (tonality and musical tempo) and individual factors (a listener's level of musical sophistication) on subjective estimates of duration. Participants estimated the duration of different versions of newly composed instrumental music stimuli under retrospective and prospective conditions. Stimuli varied in tempo (90-120 bpm) and tonality (tonal-atonal), in a 2 × 2 factorial design, while other musical parameters remained constant. Estimates were made using written estimates of minutes and seconds in Experiment 1, and the reproduction method in Experiment 2. Two-way analyses of variance (ANOVAs) showed no main effect of tonality on estimates and no significant interactions between tempo and tonality, under any condition. Musical tempo significantly affected estimates, with the faster tempo leading to longer estimates, but only in the prospective condition, and with the use of the reproduction method. Correlation matrices using the Pearson correlation coefficient found no correlation between musical sophistication scores (measured using the Goldsmiths Musical Sophistication Index [Gold-MSI]) and verbal or reproduction estimates. In conclusion, together with the existing literature, findings suggest that (1) changes in tonality, without further changes in rhythm, metre, or melodic contour, do not significantly affect estimates; (2) small changes in musical tempo influence only prospective reproduction estimates, with larger tempo differences or longer stimuli being needed to cause changes in retrospective estimates; (3) participants' level of musical sophistication does not impact estimates of musical duration; and (4) empirical research on music listening and subjective time must consider potential method-dependent results.

Cycling versus swapping strategies in psoriatic arthritis: results from the rheumatic diseases Portuguese register.

OBJECTIVE: To compare the 2-year retention rate between a second tumor necrosis factor alpha inhibitor (TNFi) and secukinumab (SEK) or ustekinumab (UST), in Psoriatic Arthritis (PsA) patients with previous inadequate response to their first TNFi. METHODS: Prospective longitudinal cohort study with a follow-up period of 2 years using the Nationwide Portuguese Reuma.pt database. Patients with a clinical diagnosis of PsA who also fulfill the CASPAR classification criteria, with previous treatment failure to a first-line TNFi and having started a second biotechnological drug (TNFi, SEK or UST) were included. The Cycling group was defined as switching from a first TNFi to a second TNFi, and the Swapping group as switching from a first TNFi to SEK or UST. Sociodemographic data, disease characteristics, disease activity scores and physical function at baseline and after 6, 12 and 24 months were recorded. Cox-proportional hazards regression was used to compare retention rates between Cycling and Swapping groups. To obtain a predictor model of 2-year discontinuation, a multivariable Cox regression model was performed. RESULTS: In total, 439 patients were included, 58% were female, with a mean age (standard deviation) of 49 (12) years. Globally, 75.6% initiated a second TNFi (Cycling group), and 24.4% started SEK/UST (Swapping group). The retention rates after 6, 12 and 24 months were 72%/66%/59% in the Cycling group; and 77%/66%/59% in the Swapping group. There were no significant differences in retention rates between both strategies (HR: 1.06, 95% CI 0.72-1.16). After 2 years of follow-up, 34.4% of patients discontinued their second biologic, mainly due to inefficacy (72.8%), with no differences found between groups. Baseline treatment with glucocorticoids was the only predictor of discontinuation after 2 years of follow-up (HR:1.668, 95% CI 1.154-2.409). CONCLUSIONS: After failure of a first TNF inhibitor, Cycling and Swapping strategies result in similar retention rates suggesting that both are acceptable in the management of patients with psoriatic arthritis.

Fracture Resistance of Fiber-Reinforced Composite Restorations: A Systematic Review and Meta-Analysis.

Composite resin is universally used for posterior teeth restorations. Fibers have been suggested for the mechanical improvement of the restorations. This study assessed the fracture resistance of class II fiber-reinforced composite restorations and compared it with the fracture resistance of three control groups: (1) healthy teeth, (2) non-fiber-reinforced restorations and (3) unrestored cavities. A search was performed using PubMed, Web of Science and Google Scholar from 15 May to 12 June 2023. Only in vitro studies from the last 10 years were included for this systematic analysis. This study was registered in the PROSPERO database, it followed PRISMA guidelines and the risk of bias was assessed using the QUIN tool. Fracture resistance median values, in Newtons (N), were calculated for the experimental and control groups (95% confidence interval). For pairwise comparison, nonparametric tests (p < 0.05) were applied. Twenty-four in vitro studies met the inclusion criteria. The fracture resistance of the experimental group was 976.0 N and differed (p < 0.05) from all controls. The experimental group showed lower values of fracture resistance than healthy teeth (1459.9 N; p = 0.048) but higher values than non-fiber-reinforced restorations (771.0 N; p = 0.008) and unrestored cavities (386.6 N; p < 0.001). In vitro systematic outcomes evidenced that glass and/or polyethylene fibers improved the fracture resistance of composite restorations.

Novel Foscan®-derived ring-fused chlorins for photodynamic therapy of cancer.

Photodynamic therapy (PDT) is an established anticancer treatment that combines the use of a photosensitiser (PS) and a light source of a specific wavelength for the generation of reactive oxygen species (ROS) that are toxic to the tumour cells. Foscan® (mTHPC) is a clinically-approved chlorin used for the PDT treatment of advanced head and neck, prostate and pancreatic cancers but is characterized by being photochemically unstable and associated with prolonged skin photosensitivity. Herein, we report the synthesis of new 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-fused chlorins, having the meso-tetra(3-hydroxyphenyl)macrocycle core of mTHPC, by exploring the [8π + 2π] cycloaddition of a meso-tetra(3-hydroxyphenyl)porphyrin derivative with diazafulvenium methides. These chlorins have photochemical properties similar to Foscan® but are much more photostable. Among the novel compounds, two chlorins with a hydroxymethyl group and its azide derivative present in the 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-fused system, are promising photodynamic agents with activity in the 100 nM range against triple-negative breast cancer cells and, in the case of azidomethyl chlorin, a safer phototherapeutic index compared to Foscan®.

Photodynamic therapy changes tumour immunogenicity and promotes immune-checkpoint blockade response, particularly when combined with micromechanical priming.

Photodynamic therapy (PDT) with redaporfin stimulates colon carcinoma (CT26), breast (4T1) and melanoma (B16F10) cells to display high levels of CD80 molecules on their surfaces. CD80 overexpression amplifies immunogenicity because it increases same cell (cis) CD80:PD-L1 interactions, which (i) disrupt binding of T-cells PD-1 inhibitory receptors with their ligands (PD-L1) in tumour cells, and (ii) inhibit CTLA-4 inhibitory receptors binding to CD80 in tumour cells. In some cancer cells, redaporfin-PDT also increases CTLA-4 and PD-L1 expressions and virtuous combinations between PDT and immune-checkpoint blockers (ICB) depend on CD80/PD-L1 or CD80/CTLA-4 tumour overexpression ratios post-PDT. This was confirmed using anti-CTLA-4 + PDT combinations to increase survival of mice bearing CT26 tumours, and to regress lung metastases observed with bioluminescence in mice with orthotopic 4T1 tumours. However, the primary 4T1 responded poorly to treatments. Photoacoustic imaging revealed low infiltration of redaporfin in the tumour. Priming the primary tumour with high-intensity (~ 60 bar) photoacoustic waves generated with nanosecond-pulsed lasers and light-to-pressure transducers improved the response of 4T1 tumours to PDT. Penetration-resistant tumours require a combination of approaches to respond to treatments: tumour priming to facilitate drug infiltration, PDT for a strong local effect and a change in immunogenicity, and immunotherapy for a systemic effect.

Antimicrobial Resistance, Virulence Properties and Genetic Diversity of Salmonella Typhimurium Recovered from Domestic and Imported Seafood.

The quantity of seafood imported and produced by domestic aquaculture farming has increased. Recently, it has been reported that multidrug-resistant (MDR) Salmonella Typhimurium may be associated with seafood. However, information is limited to the antimicrobial resistance, virulence properties, and genetic diversity of S. Typhimurium recovered from imported and domestic seafood. This study investigated the antimicrobial resistance, virulence properties, and genetic diversity of S. Typhimurium isolated from domestic and imported catfish, shrimp, and tilapia. A total of 127 isolates were tested for the presence of multidrug-resistance (MDR), virulence genes (invA, pagC, spvC, spvR), and genetic diversity using the Sensititre micro-broth dilution method, PCR, and pulsed-field gel electrophoresis (PFGE), respectively. All isolates were uniformly susceptible to six (amoxicillin/clavulanic acid, ceftiofur, ceftriaxone, imipenem, nitrofurantoin, and trimethoprim/sulfamethoxazole) of the 17 tested antimicrobials and genetically diverse. Fifty-three percent of the Salmonella isolates were resistant to at least one antimicrobial and 49% were multidrug resistant. Ninety-five percent of the isolates possessed the invA gene, 67% pagC, and 43% for both spvC, and spvR. The results suggest that S. Typhimurium recovered from seafood is frequently MDR, virulent, and have the ability to cause salmonellosis.

Calibration Assessment of Low-Cost Carbon Dioxide Sensors Using the Extremely Randomized Trees Algorithm.

As the monitoring of carbon dioxide is an important proxy to estimate the air quality of indoor and outdoor environments, it is essential to obtain trustful data from CO2 sensors. However, the use of widely available low-cost sensors may imply lower data quality, especially regarding accuracy. This paper proposes a new approach for enhancing the accuracy of low-cost CO2 sensors using an extremely randomized trees algorithm. It also reports the results obtained from experimental data collected from sensors that were exposed to both indoor and outdoor environments. The indoor experimental set was composed of two metal oxide semiconductors (MOS) and two non-dispersive infrared (NDIR) sensors next to a reference sensor for carbon dioxide and independent sensors for air temperature and relative humidity. The outdoor experimental exposure analysis was performed using a third-party dataset which fit into our goals: the work consisted of fourteen stations using low-cost NDIR sensors geographically spread around reference stations. One calibration model was trained for each sensor unit separately, and, in the indoor experiment, it managed to reduce the mean absolute error (MAE) of NDIR sensors by up to 90%, reach very good linearity with MOS sensors in the indoor experiment (r2 value of 0.994), and reduce the MAE by up to 98% in the outdoor dataset. We have found in the outdoor dataset analysis that the exposure time of the sensor itself may be considered by the algorithm to achieve better accuracy. We also observed that even a relatively small amount of data may provide enough information to perform a useful calibration if they contain enough data variety. We conclude that the proper use of machine learning algorithms on sensor readings can be very effective to obtain higher data quality from low-cost gas sensors either indoors or outdoors, regardless of the sensor technology.

Trial watch: an update of clinical advances in photodynamic therapy and its immunoadjuvant properties for cancer treatment.

Photodynamic therapy (PDT) is a medical treatment used to target solid tumors, where the administration of a photosensitizing agent and light generate reactive oxygen species (ROS), thus resulting in strong oxidative stress that selectively damages the illuminated tissues. Several preclinical studies have demonstrated that PDT can prime the immune system to recognize and attack cancer cells throughout the body. However, there is still limited evidence of PDT-mediated anti-tumor immunity in clinical settings. In the last decade, several clinical trials on PDT for cancer treatment have been initiated, indicating that significant efforts are being made to improve current PDT protocols. However, most of these studies disregarded the immunological dimension of PDT. The immunomodulatory properties of PDT can be combined with standard therapy and/or emerging immunotherapies, such as immune checkpoint blockers (ICBs), to achieve better disease control. Combining PDT with immunotherapy has shown synergistic effects in some preclinical models. However, the value of this combination in patients is still unknown, as the first clinical trials evaluating the combination of PDT with ICBs are just being initiated. Overall, this Trial Watch provides a summary of recent clinical information on the immunomodulatory properties of PDT and ongoing clinical trials using PDT to treat cancer patients. It also discusses the future perspectives of PDT for oncological indications.

Surveillance and high vaccination coverage: how Portugal overcame the collapse and regained control of the pandemic. / Vigilância e elevada cobertura vacinal: como Portugal superou o colapso e retomou o controle da pandemia.

The uncertainties about COVID-19 require evaluating national responses to identify successes and failures in the pandemic control. This article analyzes Portugal´s response, particularly the contribution of its health and surveillance systems in dealing with the pandemic. An integrative literature review was conducted, including consultations of observatories, documents, and institutional websites. Portugal´s response was agile and showed unified technical and political coordination, including surveillance structure using telemedicine. The reopening was supported by high testing and low positivity rates and strict rules. However, the relaxation of measures as of November/2020 resulted in an increase in cases, collapsing the health system. The response involved a consistent surveillance strategy with innovative monitoring tools, which, combined with high population adherence to vaccination, led to overcoming that moment and kept hospitalization and death rates at new disease waves at low levels. Thus, the Portuguese case discloses the risks of disease resurgence with the flexibility of measures and the population´s exhaustion in the face of restrictive measures and new variants, but also the importance of articulation between technical coordination, the political sphere, and the scientific committee.

As incertezas sobre a COVID-19 requerem avaliação das respostas nacionais, visando identificar sucessos e fracassos no seu controle. Este artigo analisou a resposta portuguesa, particularmente a contribuição dos seus sistemas de saúde e de vigilância no enfrentamento à pandemia. Foi realizada uma revisão integrativa da literatura, sendo incluídas consultas a observatórios, documentos e sites institucionais. A resposta portuguesa foi ágil e revelou uma coordenação técnica e política unificada. Contou com estrutura de vigilância e uso de telemedicina. A reabertura foi amparada na alta testagem, baixa positividade e regras rígidas. Contudo, o relaxamento das medidas a partir de novembro/2020 resultou em aumento de casos com colapso do sistema de saúde. A resposta a esta situação envolveu estratégia de vigilância consistente, com instrumentos de monitoramento inovadores, que, aliados à alta adesão da população à vacinação, levaram à superação daquele momento e mantiveram baixos índices de hospitalizações e óbitos em novas ondas. Nesse sentido, o caso português evidenciou os riscos de recrudescimento com a flexibilização, a exaustão da população em relação a medidas restritivas e novas variantes, mas também a importância da articulação entre a coordenação técnica, a esfera política e o comitê científico.

Characteristics associated with poor COVID-19 outcomes in people with psoriasis, psoriatic arthritis and axial spondyloarthritis: data from the COVID-19 PsoProtect and Global Rheumatology Alliance physician-reported registries.

OBJECTIVES: To investigate factors associated with severe COVID-19 in people with psoriasis (PsO), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). METHODS: Demographic data, clinical characteristics and COVID-19 outcome severity of adults with PsO, PsA and axSpA were obtained from two international physician-reported registries. A three-point ordinal COVID-19 severity scale was defined: no hospitalisation, hospitalisation (and no death) and death. ORs were estimated using multivariable ordinal logistic regression. RESULTS: Of 5045 cases, 18.3% had PsO, 45.5% PsA and 36.3% axSpA. Most (83.6%) were not hospitalised, 14.6% were hospitalised and 1.8% died. Older age was non-linearly associated with COVID-19 severity. Male sex (OR 1.54, 95% CI 1.30 to 1.83), cardiovascular, respiratory, renal, metabolic and cancer comorbidities (ORs 1.25-2.89), moderate/high disease activity and/or glucocorticoid use (ORs 1.39-2.23, vs remission/low disease activity and no glucocorticoids) were associated with increased odds of severe COVID-19. Later pandemic time periods (ORs 0.42-0.52, vs until 15 June 2020), PsO (OR 0.49, 95% CI 0.37 to 0.65, vs PsA) and baseline exposure to TNFi, IL17i and IL-23i/IL-12+23i (OR 0.57, 95% CI 0.44 to 0.73; OR 0.62, 95% CI 0.45 to 0.87; OR 0.67, 95% CI 0.45 to 0.98; respectively; vs no disease-modifying antirheumatic drug) were associated with reduced odds of severe COVID-19. CONCLUSION: Older age, male sex, comorbidity burden, higher disease activity and glucocorticoid intake were associated with more severe COVID-19. Later pandemic time periods, PsO and exposure to TNFi, IL17i and IL-23i/IL-12+23i were associated with less severe COVID-19. These findings will enable risk stratification and inform management decisions for patients with PsO, PsA and axSpA during COVID-19 waves or similar future respiratory pandemics.

Subcampos e espaços na Saúde Coletiva: fronteiras e integração / Subfields and spaces within the field of Public Health: boundaries and integration / Subcampos y espacios en la Salud Colectiva. fronteras e integración

O presente ensaio discute alguns aspectos da integração entre subcampos da Saúde Coletiva, buscando identificar obstáculos e possibilidades a esse respeito. Faz uma breve análise sobre o surgimento e o desenvolvimento dos subcampos na Saúde Coletiva e reúne indicações sobre movimentos voltados para a integração entre as áreas, bem como as suas diversas disputas. Sumariza proposições teóricas e iniciativas práticas voltadas para a interdisciplinaridade, como também desenvolvimentos teórico-conceituais. Apoiado na sociologia de Bourdieu, formula uma hipótese segundo a qual, à semelhança dos demais campos sociais, os subcampos da Saúde Coletiva se constituíram como microcosmos autônomos em que as disputas de fronteiras dominam e têm suas raízes em processos históricos e sociais. Ademais, adicionam-se os obstáculos relacionados com a incorporação do conhecimento especializado e a aquisição de habitus dos subcampos. Este ensaio discute ainda as possibilidades da integração como produto de processos coletivos ao interior da Saúde Coletiva.(AU)

This essay discusses aspects of integration between public health subfields, highlighting obstacles and possibilities. We present a brief analysis of the emergence and development of public health subfields, focusing on movements geared towards the integration of areas and the various disputes within these areas. We outline theoretical propositions and practical initiatives oriented towards interdisciplinarity and underline theoretical and conceptual developments. Drawing on Bourdieu's sociology, we propose that, like other social fields, public health subfields constitute autonomous microcosms rooted in historical and social processes dominated by boundary disputes. In addition to the above, we highlight obstacles related to the incorporation of specialist knowledge and the acquisition of habitus by the subfields. Finally, we discuss possibilities of integration as a product of collective processes within the field of public health.(AU)

Influence of Psychological Capital on the Gross Performance of Telesales Salespeople in a Wholesaler-Distributor Company / Impacto do Capital Psicológico no Desempenho Bruto dos Vendedores de Televendas em uma Empresa Atacadista Distribuidor

Abstract Raw performance and the factors that influence it is a relatively rare topic in Organizational and Work Psychology, especially in the context of Positive Organizational Behavior. This study aimed to verify whether psychological capital predicts the performance of salespeople in a wholesaler-distributor. The sample consisted of 237 salespeople who responded to the Inventory of Psychological Capital at Work (ICPT-25). The model test was performed through Structural Equation Modeling (SEM), which indicated that the proposed model, in which psychological capital predicted gross performance, was not corroborated. We argue that situational variables can be more robust predictors than individual variables. We propose that raw performance should be investigated with independent variables of a situational nature, such as leadership.

RESUMO O objetivo deste estudo foi verificar se capital psicológico pode influenciar o desempenho bruto de vendedores de televendas pertencentes a um atacadista distribuidor. A amostra final constituiu-se de 237 vendedores, sendo a maioria do sexo feminino (82,7%), com idade média de 30 anos (DP = 7,63), com tempo médio de trabalho na organização igual a 42,5 meses (DP = 47,5 meses) e o tempo médio na função de 46,7 meses (DP = 45,5 meses). O grau de escolaridade predominante é o segundo grau completo (40,5%). O instrumento utilizado foi o Inventário de Capital Psicológico no Trabalho (ICPT-25), composto por quatro fatores e com Alpha de Cronbach superior a 0,70 para cada um. A confiabilidade das escalas para a amostra do estudo também mostrou coeficientes superiores a 0,70. Os dados foram analisados por meio da estatística descritiva e o teste do modelo através da Modelagem por Equação Estrutural (MEE). Os resultados indicaram que as correlações entre capital psicológico e desempenho bruto foram baixas e as maiores correlações foram entre otimismo e esperança e autoeficácia com esperança. A MEE mostrou que o modelo proposto não foi confirmado revelando que capital psicológico não é um preditor significativo de desempenho dos vendedores que compuseram esta amostra. Recomenda-se que, em futuras pesquisas, desempenho bruto seja investigado com variáveis independentes de caráter situacionais, como liderança, por exemplo. O estudo apresentou contribuições para o meio acadêmico ao investigar desempenho bruto como variável dependente, o que é inovador dentro da POT. Para os gestores, o trabalho discute os fatores que podem determinar o desempenho visando o cumprimento de metas nas organizações.

Career Interventions for Promoting Gender Equality: Methodological Aspects / Intervenções de Carreira para Promoção de Igualdade de Gênero: Aspectos Metodológicos / Intervenciones Profesionales para Promover la Igualdad de Género: Aspectos Metodológicos

Abstract Women commonly face a complex network of barriers that hinder their career trajectory. Therefore, this article aims to address career interventions as a methodological strategy to minimize gender inequalities in the workplace. Given the scenario of inequalities experienced by women, attention in the development of interventions is needed, so that problems are not worsened with superficial initiatives that focus only on individuals. This article discusses gender inequality in careers; presents recommendations for research with interventions; exemplifies some interventions and provides a step-by-step guide for designing them, which consists of choosing the theoretical framework, defining the objectives, target audience and context, identifying resources, structuring the intervention, defining the content, activities and assessment. The limits and possibilities of using interventions in research on gender and career are discussed, in addition to the challenges of this scientific field.

Resumo Mulheres comumente enfrentam uma rede complexa de barreiras que prejudicam sua trajetória de carreira. Diante disso, o objetivo deste artigo consiste em abordar as intervenções de carreira como estratégia metodológica para mitigar as desigualdades de gênero no mundo do trabalho. Considerando o cenário de desigualdades vivido pelas mulheres, é necessário atenção na construção de intervenções, para que os problemas não se agravem com iniciativas superficiais e que focam apenas nos indivíduos. Este estudo discute a desigualdade de gênero nas carreiras; faz recomendações para pesquisas com foco em intervenções; exemplifica algumas intervenções e fornece um passo-a-passo para a elaboração de intervenções, que consiste na escolha do referencial teórico, definição dos objetivos, público-alvo e contexto, identificação dos recursos, estruturação da intervenção, definição do conteúdo, das atividades e avaliação. São discutidos os limites e possibilidades do uso das intervenções em pesquisas sobre gênero e carreira, além dos desafios desse campo científico.
