Care Management in Scientific Production in Integrative Oncology in Latin America: An Integrative Review

Introduction: Including traditional, complementary and integrative medicines in national health systems is a point of discussion worldwide. This article focuses on the theme within the scope of oncology in Latin America. Objective: To analyze the health care management dimensions included in scientific production in integrative oncology in Latin America. Materials and method: This is an integrative literature review carried out in the LILACS, Mosaico, IBECS, PubMed and Embase databases, whose guiding question was prepared according to The PRISMA 2020 Statement recommendations. The search occurred by the association of free terms related to the descriptors "Integrative Oncology," "Complementary Therapies," "Health Care," "Care Management," and "Countries That Make Up Latin America." Data were interpreted from the conceptual perspective of health care management dimensions. Results: The study selection process identified 206 studies. The final sample was made up of eight articles available online in full, published between 2017 and 2022 in Portuguese, Spanish or English. Articles were developed in Brazil (n = 4), Chile, Colombia, Peru, and Uruguay (n = 1, respectively). There was a predominance of the individual health care management dimension as the focus of analyzed studies. The "professional," "family," "societal," and "organizational" dimensions were presented in the discussion of results. Conclusions: Despite the insufficiency of studies, analysis of interdependence between dimensions indicates the complexity of the management process for integrating traditional, complementary and integrative medicine in oncological care in Latin America, which suggests an epistemology in the construction process.

Critically ill patients with COVID-19-associated acute kidney injury treated with kidney replacement therapy: Comparison between the first and second pandemic waves in São Paulo, Brazil.

INTRODUCTION: This study aimed to compare the characteristics and outcomes of critically ill patients with COVID-19-associated acute kidney injury (AKI) who were treated with kidney replacement therapy (KRT) in the first and second waves of the pandemic in the megalopolis of Sao Paulo, Brazil. METHODS: A multicenter retrospective study was conducted in 10 intensive care units (ICUs). Patients aged ≥18 years, and treated with KRT due to COVID-19-associated AKI were included. We compared demographic, laboratory and clinical data, KRT parameters and patient outcomes in the first and second COVID-19 waves. RESULTS: We assessed 656 patients (327 in the first wave and 329 in the second one). Second-wave patients were admitted later (7.1±5.0 vs. 5.6±3.9 days after the onset of symptoms, p<0.001), were younger (61.4±13.7 vs. 63.8±13.6 years, p = 0.023), had a lower frequency of diabetes (37.1% vs. 47.1%, p = 0.009) and obesity (29.5% vs. 40.0%, p = 0.007), had a greater need for vasopressors (93.3% vs. 84.6%, p<0.001) and mechanical ventilation (95.7% vs. 87.8%, p<0.001), and had higher lethality (84.8% vs. 72.7%, p<0.001) than first-wave patients. KRT quality markers were independently associated with a reduction in the OR for death in both pandemic waves. CONCLUSIONS: In the Sao Paulo megalopolis, the lethality of critically ill patients with COVID-19-associated AKI treated with KRT was higher in the second wave of the pandemic, despite these patients being younger and having fewer comorbidities. Potential factors related to this poor outcome were difficulties in health care access, lack of intra-hospital resources, delay vaccination and virus variants.

Quality of life and work engagement among nursing staff at the start of the COVID-19 pandemic. / Qualidade de vida e engajamento no trabalho em profissionais de enfermagem no início da pandemia de COVID-19.

This article investigates the correlation between work engagement and work-related quality of life among nursing staff at a public hospital in São Paulo State, at the onset of the COVID-19 pandemic. A descriptive, correlational, cross-sectional study of nursing personnel was conducted from December 2020 to January 2021, using the Brazilian versions of the Work & Well-being Survey (Utrecht Work Engagement Scale - UWES) and the Work-related Quality of Life (WRQoL) scale, following Walton's model. Nursing staffs returned a strong positive correlation (r≥0.70) between the social integration domain of the WRQoL and the vigour dimension of the UWES (r=0.88; p=<0.001); a moderate positive correlation (r≥0.40≤0.69) between working conditions (WRQOL) and the vigour (r=0.40; p<0.001), dedication (r=0.40; p<0.001) and overall score (r=0.41; p<0.001) dimensions of the UWES. Correlations were positive and weak (r≤0.39) for the other WRQoL domains and the UWES dimensions. It was concluded that personnel with satisfactory levels of quality of life tend to show higher levels of engagement at work. At the onset of the COVID-19 pandemic, nursing professionals were strongly engaged and satisfied with their work-related quality of life.

Estudo transversal, descritivo e correlacional, com profissionais de enfermagem, realizado entre dezembro de 2020 e janeiro de 2021. Foram utilizadas as versões brasileiras da Utrecht Work Engagement Scale (UWES) e da Escala de Avaliação da Qualidade de Vida no Trabalho (QVT), segundo modelo de Walton. Os profissionais de enfermagem apresentaram correlação forte e positiva (r≥0.70) entre o domínio integração social da QVT e a dimensão vigor da UWES (r=0,88; p=<0,001); correlação positiva moderada (r≥0.40≤0.69) entre as condições de trabalho (QVT) e as dimensões vigor (r=0,40; p=<0,001), dedicação (r=0,40; p=<0,001) e escore geral (r=0,41; p=<0,001) da UWES. As correlações foram positivas e fracas (r≤0.39) para os demais domínios da QVT e as dimensões da UWES. Concluiu-se que os profissionais com níveis satisfatórios de qualidade de vida tendem a ter níveis mais altos de engajamento no trabalho. No início da pandemia de COVID-19, os profissionais de enfermagem estavam fortemente engajados e satisfeitos com sua qualidade de vida no trabalho.

Pelocoris Stl, 1876 of northeastern Brazil (Hemiptera: Heteroptera: Naucoridae): first records and a key to the species.

Naucoridae is a family of aquatic bugs, distributed in tropical and subtropical regions of the world, and comprises 437 species, 47 genera, and eight subfamilies. Five subfamilies, 10 genera and 68 species have been recorded from Brazil. Pelocoris Stl is a genus exclusive to the New World, with 14 species described; eight species and two subspecies have been recorded from Brazil. For the northeastern region, there are no records of occurrence for any species in this genus. The objective of this work was to survey the fauna of Pelocoris in the northeastern region and map the distribution of the species. We examined 180 specimens belonging to six species: Pelocoris binotulatus nigriculus Berg, 1879, P. bipunctulus (Herrich-Schffer, 1853), P. magister Montandon, 1898, P. poeyi (Gurin-Mneville, 1835), P. politus Montandon, 1897, and P. subflavus Montandon, 1898. This work contributes directly to reducing the Wallacean and Linnean gaps in Naucoridae diversity for northeastern Brazil and highlights the diversity in the region, which is still poorly studied and poorly known.

Prevalence, outcomes and costs of patients with renal dysfunction in the emergency department of a specialized cardiology hospital

INTRODUCTION: Chronic kidney disease and acute kidney injury (AKI) are important complications of heart diseases. In developing countries, epidemiological and cost information on the interaction of these conditions are scarce. OBJECTIVES: To determine the prevalence, costs and outcomes of patients admitted for acute coronary syndrome (ACS) with renal dysfunction and AKI. METHODS: The study was based on a prospective database analysis of patients admitted for ACS to a Brazilian public hospital specialized in cardiology between 7/16/2018 and 12/31/2019. Renal dysfunction was defined as an estimated glomerular filtration rate (eGFR) <60ml/min/1.73m² at hospital admission. Community-acquired and hospital-acquired AKI were defined as a fall and an increase of ≥0.3mg/dl in serum creatinine from baseline, respectively. RESULTS: 1295 of the 1620 patients had a confirmed diagnosis of ACS (median age 64.2 [56.5-70.6] years, 65.4% male, 82.7% had hypertension, 45.5% diabetes and 22.6% renal dysfunction). The imaging diagnosis of ACS was coronary angiography in 84.3% and the treatment was performed by angioplasty, only clinically and by myocardial revascularization in 47.3%, 40.0% and 12.7%, respectively. Hospital- and community-acquired AKI occurred in 43.9% and 2.3% of patients, respectively. Compared with patients admitted with eGFR ≥60ml/min/1.73m², those with eGFR <60 were older (70.6 vs. 62.5 years, p<0.001), had a higher prevalence of hypertension (92.1% vs. 80.0%, p<0.001) and diabetes mellitus (60.6% vs.54.5%, p=0.010), had a higher incidence of AKI (65.0% vs. 51.4%, p <0.001) and higher: median amount reimbursed for hospitalization (1,344 [366-2,103] vs. 1,334 [290-2,018] dollars, p=0.034), median length of stay (5 [3-10] vs. 4 [2-7] days, p<0.001), death within 30 days (4.1% vs. 1.4%, p=0.004) and death within 12 months (9.2% vs. 2.9%, p<0.001). Patients with AKI, compared to those without this condition, were older (65.6 vs.63.3 years, p=0.008), had lower eGFR on admission (78.1 ml/min/1.73m² vs.86.1 ml/min/1.73m², p<0.001) and greater: median amount reimbursed for hospitalization (1,334 [301-1,865] vs. 1,724 [973-2,549] dollars, p<0.001), median length of stay (6 [4-13] vs. 3 [2-5] days, p <0.001) and death within 12 months (4.8% vs. 2.3%, p=0.032). CONCLUSIONS: In patients with ACS at a cardiology referral hospital, renal dysfunction on admission and AKI during hospitalization were frequent and associated with worse clinical and economic outcomes.

Sequential IgG antibody monitoring for virus-inactivated and adenovirus-vectored COVID-19 vaccine in Brazilian healthcare workers.

Vaccination certainly is the best way to fight against the COVID-19 pandemic. In this study, the seroconversion effectiveness of two vaccines against severe acute respiratory syndrome coronavirus 2 was assessed in healthcare workers: virus-inactivated CoronaVac (CV, n = 303), and adenovirus-vectored Oxford-AstraZeneca (AZ, n = 447). The immunoglobulin G (IgG) antibodies anti-spike glycoprotein and anti-nucleocapsid protein were assessed by enzyme-linked immunosorbent assay at the time before vaccination (T1), before the second dose (T2), and 30 days after the second dose (T3). Of all individuals vaccinated with AZ, 100% (n = 447) exhibited seroconversion, compared to 91% (n = 276) that were given CV vaccine. Among individuals who did not respond to the CV, only three individuals showed a significant increase in the antibody level 4 months later the booster dose. A lower seroconversion rate was observed in elders immunized with the CV vaccine probably due to the natural immune senescence, or peculiarity of this vaccine. The AZ vaccine induced a higher humoral response; however, more common side effects were also observed. Nonvaccinated convalescent individuals revealed a similar rate of anti-spike IgG to individuals that were given two doses of CV vaccine, which suggests that only a one-shot COVID-19 vaccine could produce an effective immune response in convalescents.

Serological Testing for COVID-19, Immunological Surveillance, and Exploration of Protective Antibodies.

Serological testing is a powerful tool in epidemiological studies for understanding viral circulation and assessing the effectiveness of virus control measures, as is the case of SARS-CoV-2, the pathogenic agent of COVID-19. Immunoassays can quantitatively reveal the concentration of antiviral antibodies. The assessment of antiviral antibody titers may provide information on virus exposure, and changes in IgG levels are also indicative of a reduction in viral circulation. In this work, we describe a serological study for the evaluation of antiviral IgG and IgM antibodies and their correlation with antiviral activity. The serological assay for IgG detection used two SARS-CoV-2 proteins as antigens, the nucleocapsid N protein and the 3CL protease. Cross-reactivity tests in animals have shown high selectivity for detection of antiviral antibodies, using both the N and 3CL antigens. Using samples of human serum from individuals previously diagnosed by PCR for COVID-19, we observed high sensitivity of the ELISA assay. Serological results with human samples also suggest that the combination of higher titers of antiviral IgG antibodies to different antigen targets may be associated with greater neutralization activity, which can be enhanced in the presence of antiviral IgM antibodies.

Prevention of radial artery occlusion after transradial access using nitroglycerin (Patens Trial)

BACKGROUND The use of transradial access (TRA) for coronary catheterization has increased over the years because of the reduced rates of vascular complications and easier postprocedural manage ment. Radial artery occlusion (RAO) remains the Achilles heel of TRA. Intra-arterial nitroglycerin could result in a significant reduction of RAO. The vasodilation may enhance antegrade flow in the artery that reduces stasis-induced thrombosis, but it could also minimize endo thelial trauma when used early in the procedure. The main objective of this study is to evaluate whether nitroglycerin at the beginning or end of TRA may preserve the patency of the artery. METHODS We conducted a prospective, multicenter, randomized, 2 2 factorial, placebo-controlled, 2-blinded study and enrolled patients submitted to catheterization by TRA. Patients received either 500 mg nitroglycerin or placebo given intra-arterially through the sheath at 2 moments: early, after sheath insertion, and late, at the end of the radial procedure. All patients received at least 5,000 UI heparin, sheaths were removed immediately after the catheterization, and a radial pneumatic wristband was applied intending patent or minimum pressure hemostasis. The primary outcome was the incidence of RAO, verified by Doppler evaluation within the first 24 hours, and every patient with confirmed RAO was further evaluated 30 days later. RESULTS A total of 1,894 patients were enrolled, with a mean age of 61.7 10.3 years. The majority (61.6%) were male, and 36.5% had diabetes. The clinical indication was ACS in 47.9%. RAO occurred in 49 patients (2.6%) by Doppler evaluation. Fifteen patients (30.6%) showed re-establishment of flow at 30-day Doppler assessment. Nitroglycerin, as compared with placebo, did not reduce the risk of RAO in either of the 2 moments used (early: 2.4% vs 2.8%, P » 0.65 or late: 2.8% vs 2.4%, P » 0.65, respectively). In the multivariate anal ysis, the size of the radial artery, obtaining access with a single puncture, operator inexperience, and the presence of spasm were associated with RAO. CONCLUSION In the present study, the use of nitroglycerin is not associated with a reduced incidence of RAO regardless of the admin istration time

Mid- to long-term clinical and echocardiographic outcomes after transcatheter aortic valve replacement with a new-generation, self-expandable system.

OBJECTIVES: The aim of the study was to evaluate mid- to late clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) with Acurate neo™ (Boston Scientific, Boston, MA). BACKGROUND: TAVR is an established treatment for aortic stenosis (AS). Few data exist on mid- to long-term outcomes and durability after new-generation valves. METHODS: All consecutive patients (n = 104) who underwent Acurate neo™ implantation from 2012 to 2018 were included. Follow-up was systematically performed at 1, 6, 12, and 24 months and yearly thereafter. Outcomes were reported according to VARC-2, and structural valve deterioration (SVD) or bioprosthetic valve failure defined accordingly to new definitions. RESULTS: Mean age was 82 ± 5.4 years, 56.7% were female and the Society of Thoracic Surgeons score for mortality was 5.9 ± 4%. Patients were followed for a median of 3 years (1,092 days; IQR 1.5-4 years), and the maximum follow-up was 7 years. All-cause mortality values at 1 and 5 years were 8.5% and 40.5%, respectively. No relevant changes in mean gradient and orifice area occurred (7.9 ± 3.8 mmHg and 1.9 ± 0.3 cm2 at 1 year; 6.6 ± 2.1 mmHg and 1.8 ± 0.3 cm2 at 5 years), and there was a significant rate of paravalvular leaks resolution at 1, 2, and 3 years (p = .004; p < .001; p < .001, respectively). None of the patients had leaflet thrombosis or endocarditis. One patient developed SVD at 84 months. CONCLUSIONS: Acurate neo™ was associated with sustained echocardiographic results. Reassuring mid- to long-term outcomes was observed in this cohort of elderly patients with severe AS.

Nursing diagnosis/outcomes and interventions for critically ill patients affected by covid-19 and sepsis / Diagnósticos/resultados e intervenciones de enfermería para pacientes graves afectados por covid-19 y por sepsis / Diagnósticos/resultados e intervenções de enfermagem para pacientes graves acometidos por covid-19 e sepse

ABSTRACT Objective: to relate nursing diagnoses/outcomes and interventions for critically ill patients affected by COVID-19 and sepsis in the Intensive Care Unit, according to the International Classification for Nursing Practice (ICNP®). Method: a documentary study conducted in March and April 2020 from the ICNP® terminology subset for adult patients with sepsis. The documentary corpus was composed of the list of nursing diagnoses/outcomes and interventions based on Horta's Theory of Basic Human Needs; on the 7-Axis Model of the International Classification for Nursing Practice, version 2017; on the Pathophysiological model of sepsis; as well as relying on the authors' expertise in direct care for suspected or confirmed critically ill patients affected by COVID-19. Outcomes: a total of 58 nursing diagnoses/outcomes were identified that belong to the psychobiological needs of oxygenation (13-22.4%), vascular regulation (12-20.7%), neurological regulation (10-17.2%), hydration (08-13.8%), elimination (08-13.8%), immunological regulation (04-6.9%) and thermal regulation (03-5.2%), evidencing a total of 172 nursing interventions with a mean of 03 for each nursing diagnosis/outcome. Conclusion: data analysis provided greater knowledge about the disease and the nursing process in the ICU setting, serving as a guide for the professional practice for critically ill patients hospitalized with COVID-19 and sepsis.

Effect of Preloading With High Dose of Rosuvastatin on Serum Levels of Inflammatory Markers After Percutaneous Coronary Intervention.

OBJECTIVES: We sought to assess the effects of a high loading dose of rosuvastatin (40 mg) on acute inflammatory response after coronary stenting. METHODS: Patients with stable coronary disease without statin use (≥7 days) and undergoing elective percutaneous coronary intervention (PCI) in a native coronary artery were randomized to receive a loading dose of rosuvastatin (n = 64) or not (n = 61). Blood samples were obtained before statin intake (time point A), 3 hours after medication (time point B), and 3 hours after PCI (time point C). The primary goal was the comparison in the variation of the serum inflammatory markers and their gene expression at the different time points between the two groups. RESULTS: Baseline clinical, angiographic, and procedural characteristics did not significantly differ between the groups, except for the more frequent use of postdilation in the control group (73.4% vs 90.2%; P=.02). Patients pretreated with statin showed a reduction in the serum levels of interleukin (IL)-1ß (Δ = -0.491 pg/mL; Pinteraction<.001), IL-6 (Δ = -0.209 pg/mL; Pinteraction<.001), and plasminogen activator inhibitor 1 (Δ = -1.573 pg/mL; Pinteraction<.001) as well as in their genetic expression, which was not observed in the control group. Regarding high-sensitivity c-reactive protein, there was no significant variation in its value from time point A to C in patients pretreated with statin (P=.58) while it significantly increased in the control group (P=.04). CONCLUSIONS: Among patients with stable coronary artery disease undergoing PCI with stents, pretreatment with high dose of rosuvastatin resulted in significant reduction in the serum levels of important inflammatory markers and their genetic expression.

Mid- to long-term clinical and echocardiographic outcomes after transcatheter aortic valve replacement with a newgeneration, self-expandable system / Desfechos clínicos e ecocardiográficos de médio a longo prazo após a substituição da válvula aórtica transcateter com uma nova geração, sistema auto-expansível

Abstract Objectives: The aim of the study was to evaluate mid- to late clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) with A curate neo™ (Boston Scientific, Boston, MA). Background: TAVR is an established treatment for aortic stenosis (AS). Few data exist on mid- to long-term outcomes and durability after new-generation valves. Methods: All consecutive patients (n = 104) who underwent A curate neo™ implantation from 2012 to 2018 were included. Follow-up was systematically performed at 1, 6, 12, and 24 months and yearly thereafter. Outcomes were reported according to VARC-2, and structural valve deterioration (SVD) or bioprosthetic valve failure defined accordingly to new definitions. Results: Mean age was 82 ± 5.4 years, 56.7% were female and the Society of Thoracic Surgeons score for mortality was 5.9 ± 4%. Patients were followed for a median of 3 years (1,092 days; IQR 1.5­4 years), and the maximum follow-up was 7 years. All-cause mortality values at 1 and 5 years were 8.5% and 40.5%, respectively. No relevant changes in mean gradient and orifice area occurred (7.9 ± 3.8 mmHg and 1.9 ± 0.3 cm2 at 1 year; 6.6 ± 2.1 mmHg and 1.8 ± 0.3 cm2 at 5 years), and there was a significant rate of paravalvular leaks resolution at 1, 2, and 3 years (p = .004; p < .001; p < .001, respectively). None of the patients had leaflet thrombosis or endocarditis. One patient developed SVD at 84 months. Conclusions: A curate neo™ was associated with sustained echocardiographic results. Reassuring mid- to long-term outcomes was observed in this cohort of elderly patients with severe AS.

Comparison of minimum pressure and patent hemostasis on radial artery occlusion after transradial catheterization

ABSTRACT: Objectives. The aim of this study was to compare two hemostatic techniques, minimum pressure technique and patent hemostasis, on radial artery occlusion (RAO) after trans-radial catheterization. Background. RAO is an infrequent complication of trans-radial procedures. One of the strategies used to reduce this complication is the patent hemostasis technique. Use of minimum pressure in hemostatic wristband, without monitoring patency, might have the same efficacy for preventing RAO. Methods. This is a multicenter study encompassing patients submitted to trans-radial catheterization. After pneumatic wristband application, the band was deflated to the lowest allowable volume while preserving hemostasis. Radial artery patency was subsequently evaluated. The group with no return of plethysmography curve was labeled "minimum pressure," and the group in which the signal returned was labeled "patent hemostasis." RAO was verified by Doppler evaluation within the first 24 hours of the procedure. Results. A total of 1082 patients were enrolled, with mean age of 61.4 ± 10.4 years. The majority (61.0%) were male and 34.5% had diabetes. Patent hemostasis was achieved in only 213 cases (20%). Early RAO occurred in 16 patients (1.8%) in the minimum pressure group and in 4 patients (1.9%) in the patent hemostasis group (P=.97). No major bleeding was observed among the entire cohort. EASY scale for hematoma grade was similar between the cohorts (EASY grades 1-3: 7.0% in the minimum pressure group vs 7.5% in the patent hemostasis group; P=.96). Conclusion. Checking radial patency during hemostatic compression may not be necessary after the procedure when adopting a mild and short hemostatic compression
