Phaseolotoxin is a major virulence factor of the bean pathogen bacterium P. savastanoi pv. phaseolicola. This toxin plays a key role in the development of the halo blight disease in bean plants. So far, the signal transduction pathways involved in the synthesis of phaseolotoxin have not been elucidated. The influence of regulation mechanisms related to the oxidative stress response, in particular the OxyR protein, it has been suggested to be involved in this process.. In this study we evaluated the role of OxyR in P. savastanoi pv. phaseolicola, mainly compared to the synthesis of phaseolotoxin and the virulence of this phytopathogen. Generation of the oxyR-mutant, pathogenicity and virulence tests, and analyses of gene expression by RT-PCR assays were performed. The results showed that OxyR exerts an effect on the synthesis of phaseolotoxin and positively influences the expression of the Pht and Pbo cluster genes. Likewise, OxyR influences the production of pyoverdine by the control of the expression of the genes encoding the PvdS sigma factor, involved in the synthesis of this pigment. This study is the first report on members of the OxyR regulon of P. savastanoi pv. phaseolicola NPS3121.

Published: October 2022

Periodontitis, as one of the most common diseases on a global scale, is a public health concern. Microbial resistance to currently available antimicrobial agents is becoming a growing issue in periodontal treatment. As a result, it is critical to develop effective and environmentally friendly biomedical approaches to overcome such challenges. The investigation of Streptomyces rochei MS-37’s performance may be the first of its kind as a novel marine actinobacterium for the green biosynthesis of silver nanoparticles (SNPs) and potentials as antibacterial, anti-inflammatory, antibiofilm, and antioxidant candidates suppressing membrane-associated dental infections. Streptomyces rochei MS-37, a new marine actinobacterial strain, was used in this study for the biosynthesis of silver nanoparticles for various biomedical applications. Surface plasmon resonance spectroscopy showed a peak at 429 nm for the SNPs. The SNPs were spherical, tiny (average 23.2 nm by TEM, 59.4 nm by DLS), very stable (−26 mV), and contained capping agents. The minimum inhibitory concentrations of the SNPs that showed potential antibacterial action ranged from 8 to 128 µg/mL. Periodontal pathogens were used to perform qualitative evaluations of microbial adhesion and bacterial penetration through guided tissue regeneration membranes. The findings suggested that the presence of the SNPs could aid in the suppression of membrane-associated infection. Furthermore, when the anti-inflammatory action of the SNPs was tested using nitric oxide radical scavenging capacity and protein denaturation inhibition, it was discovered that the SNPs were extremely efficient at scavenging nitric oxide free radicals and had a strong anti-denaturation impact. The SNPs were found to be more cytotoxic to CAL27 than to human peripheral blood mononuclear cells (PBMCs), with IC50 values of 81.16 µg/mL in PBMCs and 34.03 µg/mL in CAL27. This study’s findings open a new avenue for using marine actinobacteria for silver nanoparticle biosynthesis, which holds great promise for a variety of biomedical applications, in particular periodontal treatment.

Published: October 2022

Lubricant additives can effectively enhance the performance and environmental adaptability of lubricants and reduce the energy loss and machine wear caused by friction. Nanomaterials, as important additive materials, have an essential role in the research and development of new lubricants, whose lubrication performances and mechanisms are not only related to their physical and chemical properties, but also influenced by the geometric shape. In this paper, the friction reduction and antiwear performances of nanomaterials as lubricant additives are first reviewed according to the classification of the dimensions, and their lubrication mechanisms and influence rules are revealed. Second, the recent research progress of composite nanomaterials as lubrication additives is introduced, focusing on their synergistic mechanism to improve the lubrication performance further. Finally, we briefly discuss the challenges faced by nanoadditives and provide an outlook on future research. The review expects to provide new ideas for the selection and development of lubricant additives to expand the application of nanoadditives.

Published: October 2022

Spotted fever group rickettsioses (SFGR) are caused by a group of tick-borne pathogens that are increasing in incidence globally. These diseases are typically underreported and undiagnosed in low- and middle-income countries, and thus, have been classified as neglected bacterial pathogens. Countries with high poverty, low human development index score, and limited health infrastructure—like El Salvador in Central America—lack necessary surveillance for SFGR and other tick-borne pathogens. This paucity of baseline SFGR infection prevalence leaves vulnerable populations at risk of misdiagnosis. Further, tick-borne disease burdens in El Salvador are severely limited. To lay the foundation for tick-borne disease epidemiology in El Salvador, our team conducted two different enzyme-linked immunosorbent assays (ELISA) on banked human sera samples from a cohort of approximately 1000 pediatric participants from a high-risk vector-borne disease population. Eleven percent of all tested banked pediatric sera were positive for at least one ELISA assay at the time of enrollment: 10.7% were positive for only IgM antibodies (acute SFGR infection), and 2.5% were positive for IgG antibodies (a past SFGR infection). Older, male, children enrolled during the wet season, with a household history of infectious disease and higher maternal education level had higher odds of SFGR antibodies. Additionally, children from households with domestic poultry birds and previous knowledge of other vector-borne diseases had significantly reduced odds of SFGR antibodies. The large percentage of acute SFGR infections indicates that it continues to remain an underreported and undiagnosed issue in El Salvador and the Central American region. Much is still unknown regarding the complexity of the tick, animal host, and human host ecology transmission cycle of SFGR in El Salvador.

Balantioides coli is a zoonotic enteric protozoan parasite of public veterinary health relevance and a concern in animal production and food safety. While wild cervids are recognized reservoirs for several zoonotic pathogens, little is known about the occurrence of B. coli in deer species, especially in Europe. To fill this gap, a total of 130 fecal samples from legally hunted red deer (Cervus elaphus, n = 95) and fallow deer (Dama dama, n = 35) were passively collected during two hunting seasons (October to February; 2018–2019 and 2019–2020) in Portugal. After assessment by PCR assay targeting the complete ITS1–5.8s-rRNA–ITS2 region and the 3’ end of the ssu-rRNA gene of the parasite, a prevalence of 4.2% (4/95, 95% CI: 0.2–8.3) in red deer and of 5.7% (2/35, 95% CI: 0.0–13.4) in fallow deer was found. Sequence and phylogenetic analyses allowed the identification of B. coli genetic variants A (in two red deer) and B (in two red deer and two fallow deer). This is the first molecular-based description of B. coli in European deer species, whose population have increased in density and geographical range in recent years. Continued monitoring of wild ungulates as potential vectors of parasitic infection diseases of zoonotic nature is crucial to safeguard public health and food safety.

Published: October 2022

Currently, laser systems based on active elements doped with Yb3+ with simultaneously high pulse repetition rates and high peak power are in demand for many applications. High thermal load of active elements is the primary limiting factor for average power scaling. Experimental investigation of temperature distribution in active elements is of particular importance for estimation of cooling efficiency and for thermal processes’ monitoring. In the present work, the method of dynamic laser thermometry is proposed for temperature distribution investigation within cryogenically cooled Yb3+-doped active elements. The method is based on the dependence of the Yb3+ ion absorption cross-section on temperature at a wavelength of 1030 nm. The method was tested to study the 2D temperature map of the Yb:YAG active element of the high-power, diode-pumped, cryogenically cooled laser amplifier. The best measurement accuracy ±3 K is achieved at the maximal temperature 176 K. The results of numerical simulation are in good agreement with the experimental data. On the basis of the investigation, the quality of the cooling system is evaluated. The advantages and other possible applications of the method are discussed.
Research on Rolling-Element Bearing Composite Fault Diagnosis Methods Based on RLMD and SSA-CYCBD
Authors: Ma Jie , Liang Shitong
Published: October 2022

Aiming at the problem that it is difficult to separate and extract the composite fault features of rolling-element bearings, a composite fault diagnosis method combining robust local mean decomposition (RLMD), sparrow search algorithm (SSA), maximum second-order cyclostationarity blind deconvolution (CYCBD), is proposed. First, the RLMD is used to decompose the product function of the signal, and the two indicators, the excess and the correlation coefficient are then used as evaluation criteria to select the appropriate components for reconstruction. The reconstructed signal is then inputted into the SSA-optimized CYCBD algorithm, by specifying the objective function parameter which separates the faults and obtains multiple single fault signals with optimal noise reduction. Finally, envelope demodulation analysis is used for the multiple single fault signals, to obtain the characteristic frequencies of the corresponding faults, so as to complete the fault separation and feature extraction of composite faults. In order to verify the effectiveness of the method, the initial signals and the actual signals generated by the computer shall be used. The algorithm is verified using the XJTU-SY rolling-element bearing dataset, which shows the good performance of the method.
Deformation Coupled Effective Permeability Change in Hydrate-Bearing Sediment during Depressurization
Authors: Sun Xiang , Luo Hao , Soga Kenichi
Published: October 2022

Methane hydrates found in the sediments of deep sea and permafrost regions draw global interest. The rate of gas production from a depressurized well is governed by the effective permeability of the hydrate-bearing sediments around the wellbore. During depressurization, a decrease in pore pressure leading to soil compaction and hydrate dissociation results in a dynamic change in the effective permeability. To describe the change in the effective permeability in detail, in this study, a simple coupled compressibility–permeability analysis method is proposed to identify the conditions under which the effective permeability increases or decreases after depressurization. An analytical solution is derived for the effective permeability change with pore pressure and temperature, considering hydrate dissociation and soil compaction. We found that when there is a sufficient heat supply, hydrate dissociation dominates the effective permeability during hydrate dissociation, but after hydrate dissociation, soil compaction is the governing factor for permeability change. When there is an insufficient heat supply, however, compaction mainly determines the permeability, and the effect of hydrate dissociation is limited. This work will be helpful for rapid reservoir assessment.

The subsheath of the extensor carpi ulnaris (ECU) tendon, a component of the triangular fibrocartilage complex (TFCC), is particularly important as it dynamically stabilizes the distal radioulnar joint. However, the relationship between TFCC injury and ECU dynamics remains unclear. This study aimed to analyze ECU movement and morphology using ultrasonography (US) images. Twenty wrists of patients with TFCC injury, who underwent TFCC repair, were included in the injury group, and 20 wrists of healthy volunteers were in the control group. For static image analysis, curvature and linearity ratios of the ECU in US long-axis images captured during radioulnar deviation were analyzed. For dynamic analysis of the ECU, the wrist was moved from radial deviation to ulnar deviation at a constant speed, and the velocity of the tendon was analyzed using particle image velocimetry. The static analysis showed that the ECU tendon was more curved in ulnar deviation in the injury group than in the control group, and the dynamic analysis showed that only vertical velocity toward the deep side during ulnar deviation was higher in the injury group. These results suggest that TFCC injury caused ECU curvature during ulnar deviation and increased the vertical velocity of the ECU during wrist deviation.

Published: October 2022

Otitis externa, a common disease in dogs, has different etiologies. Enterococcus is a Gram-positive bacterium that frequently causes opportunistic ear infections. Here, we determined the distribution of Enterococcus in canine otitis externa via time-of-flight mass spectrometry and biochemical tests and evaluated their resistance patterns to 10 commonly used antibiotics. Among the 197 Enterococcus isolates, E. faecalis (48.7%; 96/197) was the most common, followed by E. faecium (21.3%; 42/197), E. casseliflavus (11.7%; 23/197), E. hirae (10.7%; 21/197), E. avium (3.6%; 7/197), E. gallinarum (2.5%; 5/197), E. canintestini (1.0%; 2/197), and E. durans (0.5%; 1/197). All isolates were tested for antibiotic resistance using the Kirby–Bauer disc diffusion method. Enterococcus faecalis strains were highly resistant to erythromycin (45.8%) and rifampin (34.3%) but were generally susceptible to penicillin class antibiotics. In contrast, E. faecium isolates were highly resistant to penicillin class antibiotics (ampicillin, 61.9%; penicillin, 71.4%). Most importantly, E. faecium demonstrated high resistance to most of the antibiotics used in this study. Multidrug resistance was found in 28.4% of the isolates (56/197). This study shows prevalence and antibiotics resistance profiles of Enterococcus species in canine chronic otitis externa. The results can contribute to establish therapeutic strategies of Enterococcus infections and be used as a comparable index of antibiotic resistance of Enterococcus in the future.

Published: October 2022

O judô é uma arte marcial japonesa criada em 1882 por Jigoro Kano, e atualmente possui tradição olímpica. O propósito desse esporte é de finalizar o oponente por meio de técnicas de arremessos, estrangulamentos e de chaves de braço. Para isso, o judoca precisa estar preparado fisicamente, visto que é utilizado a força, resistência e potência muscular aliados a técnicas inerentes da modalidade para que o judoca atinja esses objetivos. O propósito do estudo foi correlacionar a resistência e potência muscular com o Special Judo Fitness Test (SJFT) em praticantes de judô da cidade de Palmas/TO. Tratou-se de uma pesquisa transversal, quantitativa, descritiva e aplicada em campo, que foi desenvolvida em uma academia de judô situada em Palmas/TO. A amostra foi composta por 11 judocas (21,73±2,76 anos) graduados na faixa marrom ou preta. O teste de Shapiro-Wilk confirmou a normalidade das variáveis. Na sequência foi aplicado o teste de correlação de Pearson. Não foi encontrado correlação significativa entre o desempenho dos praticantes de judô no SJFT com os testes de salto vertical (r= -0,49; p*=0,122) e salto horizontal (r= -0,35; p*= 0,294), já entre os de flexão de braços com o SJFT foi observado uma correlação forte (r= -0,65; p*=0,029), enquanto entre o número de repetições de flexões abdominais com o SJFT foi verificado uma correlação muito forte (r= -0,78; p*=0,004). Estudos analisados mostram que o SJFT tem boa correlação com índices de aptidão aeróbia e anaeróbia em judocas adultos e de elite. Portanto, estudos com uma amostra constituída por judocas que não sejam competidores de alto nível devem ser realizados para investigar as distinções e afinidades presentes nestas populações a fim de guiarem o treinamento desses praticantes.

In the Russian Federation, the number of women in peri- and postmenopause is more than 21 million [1]. In addition to changes in sex hormone levels associated with menopause, its timing is an important predictor of future health outcomes, such as the duration of vasomotor symptoms and the risk of developing hormone-dependent tumors. The influence of reproductive factors (e.g., age at menarche, pregnancy) and sociodemographic factors on intermediate and long-term health outcomes of menopause has been extensively studied in the past. However, the influence of a woman’s diet on the course of menopause has not been studied sufficiently. There is also little evidence in the literature on the impact of diet at a young age, the so-called established eating patterns, on the menopause course. The authors aim to study the actual nutrition of menopausal women with manifestations of climacteric syndrome and make an attempt to influence the quality of life and the manifestation of menopausal syndrome with the help of lifestyle correction, diet modification and the use of minor biologically active substances. The aim was also to determine the features of the diet of women of reproductive age (to determine the excess and lack of nutrients) in order to create an algorithm for correcting the diet and preventing delayed risk factors.

This article describes the results of an exploration of the current state of some reservoirs of the Ulan district of the East Kazakhstan region: a pond on the Karasu River 7 km upstream of the village of Privolnoye, a pond on the Karasu River 2 km upstream of the village of Mitrofanovka, a pond on the Peschanka River and a pond on the Tugulka River according to hydrochemical and hydrobiological indicators, in order to determine the status and suitability of water objects in fish breeding. Research works was carried out in 2021. Inspections of reservoirs were carried out sporadically, in connection with this, these water objects can be considered poorly studied. For the analysis of temporal changes, hydrochemical and hydrobiological samples were taken in spring, summer and autumn. The content of biogenic compounds and main ions was studied, the results obtained were compared with the values given in the Unified Classification System for Water Quality in Water Bodies, and their seasonal dynamics was also considered. The article defines the class of the reservoir by chemical composition, the category by mineralization and the class of hardness. According to the results of research, water objects are characterized by an optimal oxygen regime, slightly alkaline reaction (pH 7.2–8.7) and low salinity (310–438 mg/dm3). According to the classification of the main ions, the waters of the surveyed ponds belong to the hydrocarbonate class, the calcium group, the first type. It was determined that the concentration of biogenic compounds in 2021 does not exceed the established fishery standards. The values of the abundance and biomass of zooplankton and benthos in different seasons of research are estimated, an assessment of the trophic status of the reservoirs was given according to hydrobiological indicators and a brief physical and geographical characteristic of water objects is described. In general, the trophic class of ponds in the Ulansky district varied from very low class to high class in terms of hydrobiological indicators, which indicates a good supply of food resources. It can be noted that the maximum indicators of the development of the forage base were observed in the summer period. Based on the results of the analyzes obtained, the status and category of the studied water bodies were determined.

The cultivation of aquaculture facilities under controlled conditions consists of several stages — the formation of a breeding stock, the production of offspring and cultivation of marketable products. The duration of each stage depends on the biological characteristics of a particular aquaculture facility and environmental factors. In aquaculture of tropical species, as a rule, installations with a closed water supply cycle are used, which makes it possible to create conditions for their maintenance year-round, depending on the tasks set. At the same time, the organization of the necessary optimal temperature, hydrochemical regime, feeding regime at each technological stage allows you to control, influence and regulate the vital functions of hydrobionts, especially the duration of the reproductive cycle. Special attention is paid to the reproduction of objects. The study of biological and technological features and the creation of technology for reproduction and offspring of the Australian red-lobed cancer in industrial conditions is quite an urgent issue. The purpose of this work was to study the repair and uterine groups of cancers, their reproductive activity, as well as some features of obtaining and rearing young Australian red-lobed cancer in the conditions of ultrasound. The research work was carried out based on the scientific and experimental complex of aquaculture “BIOS” of the Volga-Caspian branch of the VNIRO Federal State Budgetary Institution ("KaspNIRKH"). The temperature conditions of keeping crayfish producers, obtaining, rearing and rearing young crayfish in the ultrasound were studied and their biological indicators were monitored. In the course of the study, the age of producers who showed reproductive activity for the first time and the output of larvae from the female, as well as the size and mass indicators of repair-uterine groups and undergrown juveniles (body weight, body length, absolute gain, etc.).

The analysis of the growth intensity showed a significant increase in body weight from the 4th week of the experiment in groups receiving separately the probiotic “Subtilis-Zh” and jointly the probiotics “Subtilis-Zh” and “ATYSH”. Hematological indicators demonstrate a significant increase in the concentration of leukocytes in the experimental group that consumed the complex of probiotic drugs “Subtilis-Zh” and “ATYSH” in comparison with the control by 19,8% (P < 0,05), respectively. A similar blood pattern was observed when studying a carp leukogram, where a significant increase in lymphocytes was found. The number of red blood cells in the blood corresponded to normal physiological values. At the same time, the indicator of hemoglobin content has increased significantly, which indicates active metabolic processes. The use of the feed probiotic additive “Subtilis-Zh” favorably affected the growth, development and hematological parameters of carp. The combined use of this drug with the feed probiotic additive “ATYSH” allowed to normalize the own bacterial flora of the intestine and strengthen the resistance of the fish organism to the effects of pathogens.

MOTIVATIONAL READINESS OF CRIMINAL INVESTIGATION DEPARTMENT OFFICERS TO PROFESSIONAL ACTIVITY
Authors: Yudina N.
Published: October 2022

The article presents the results of theoretical and experimental research of psychological peculiarities of the motivational readiness of criminal investigation department officers to professional activity. This problem was actualized by the fact that in the current conditions in many regions of the country the workload on the officers of the internal affairs bodies, in particular, the employees of the criminal investigation departments, has increased significantly.

As a result of the theoretical analysis, it was found that the complexity of the activity of criminal investigation department officers dictates the high requirements for the professional training of each officer. Investigative activity requires an officer of internal affairs bodies to have appropriate professional training and a clear understanding of the main values of the profession. The motivation of professional activity is an important component in the development of a young specialist. The formation of motivational readiness is possible under the condition of a certain social guarantee to the officer from the system of internal affairs bodies and the activation of the process of theory and practice combining during the period of mastering the profession.

The data of the experimental research of the motivational readiness of criminal investigation department officers to professional activity proved the preference of extreme types of activity among professional inclinations. These are the professions related to security and investigative activities, since different situations of an official nature are possible in the activity of law enforcement officers. Inclinations to research activity are also significant. In the hierarchy of motives for choosing a profession by officers of the criminal investigation sector of the Ministry of Internal Affairs, those motives that are significant for the implementation of the chosen professional activity, namely internal individually significant motives and external positive motives, dominate. This proves that law enforcement officers are focused on the profession and strive to work effectively on mastering it in the future, as they consider the chosen profession to be their vocation and want to reveal creatively and express themselves in it.

The attitude of the subjects to labor activity is positive in general. In addition, it was possible to prove that subjects with developed internal individually significant motives for choosing a profession have a higher level of readiness to master the profession of an investigator.

Published: October 2022

Changes in functional properties - emulsifying capacity, protein solubility, cook loBB, relative viscosity and water-binding capacity - were observed in Japanese threadfin bream (Nemipterus japonicus) during 14 days storage in ice. Decreasing solu­bility of proteins profoundly influenced the functional properties. Significant correla­tions (P<0.05) existed among various functional properties of fish protein analyzed and with texture scores. Fish held in ice was rated "'good'" for up to seven days.

Authors: SAMARASINGHE R.P.
Published: October 2022

Peneaus monodon larvae reared to Postlarva-1 stage were fed with the diatom Biddulphia longicuris. A density of 5,000 - 10,000 cells-m1·1 of B. longicuris was maintained in larval rearing tanks. The mean survival rate from zoea-1 to Mysis1 larval stage was 88.7%, and Mysis-1 to Postlarva-1 stage was 91.6%. The zoea larva metamorphosed. to the Mysis stage within four days at a temperature of 29-31 °C. The zoea larvae were fed only the B. longicuris; a microencapsulated feed was given at the Mysis stage along with the same diatom.
Some Effects of the 1990/91 Gulf War on Hamoor (Epinephelus tauvina) From the Saudi Arabian East Coast
Authors: MATHEWS C.P.
Published: October 2022

The 1990/91 Gulf War produced a heavy oil slick and a thick plume from oil fires in Kuwait, causing heavy oiling of the Saudi Arabian coast and low air temperatures and SSTs from February to at least October 1991. Ripe hamoor (Epinephelus tauuina) were taken in Saudi Arabian waters in spring 1991 but were absent in spring 1992. Parasite infestations were more frequent and heavier in spring 1992. These changes may have been caused by toxic effects of the oil, and would not appear in 1991 because fish were ripe when the pollution started. Data on pre- and postwar pollutant levels do not allow identification of possible causal agents. Sampling problems to be addressed in future baseline studies are discussed: samples need to be stratified by age.

A Atenção Primária à Saúde (APS) é componente chave para o fortalecimento dos sistemas de saúde, que visam alcançar os princípios de integralidade e equidade. No Brasil, a organização da APS é norteada pela Estratégia de Saúde da Família (ESF), que utiliza como um dos principais instrumentos avaliativos o Primary Care Assessment Tool (PCAT). Esse instrumento mede a orientação da APS à luz dos atributos essenciais (acesso de primeiro contato, longitudinalidade, integralidade e coordenação do cuidado) e derivados (orientação familiar e comunitária e competência cultural). O objetivo deste estudo é analisar o desempenho de uma Equipe de Saúde da Família (EqSF) no município de Aracaju, SE, à luz do PCAT, a fim de se obter o grau de orientação da APS. Foram entrevistados 310 adultos cadastrados maiores de 20 anos. Destes, 254 (81,9%) mostraram-se afiliados à Unidade de Saúde, sendo essa amostra utilizada para o cálculo do grau de orientação. O escore geral obtido foi de 6,8, com o valor de 6,66 sendo considerado indicativo de uma boa orientação para APS. Apesar desse resultado, foi percebido que os atributos de acesso, integralidade e orientação comunitária precisam de ajustes para que a equipe possa ofertar um serviço mais resolutivo e de qualidade.
Conexões virtuais – a tecnologia a serviço das relações profissionais
Authors: Guilam Maria Cristina Rodrigues
Published: October 2022

A oferta de ações educativas para os profissionais da saúde é pauta em diversos fóruns, seja por demandas governamentais, seja pela preocupação das instituições acadêmicas ou, ainda, das organizações da sociedade civil que compreendem a importância da aquisição de ferramentas de pesquisa aplicada à realidade por parte daqueles que estão trabalhando no cotidiano da atenção e da gestão. Há, no Brasil, uma distribuição desigual em relação às oportunidades formativas, muito concentradas nas regiões Sudeste e Sul e bastante rarefeitas em outras regiões, particularmente Norte e Centro-oeste. O artigo comenta estratégias educativas no sentido de contribuir para a redução de tais desigualdades, com destaque na constituição de redes de ensino e no aproveitamento de ferramentas virtuais.
Atenção Primária à Saúde no SUS: a indissociabilidade entre atenção, gestão e educação
Authors: Machado Cristiani Vieira
Published: October 2022

Desde a Conferência de Alma Ata, em 1978, o tema da Atenção Primária em Saúde (APS) suscita debates entre acadêmicos, gestores e profissionais de saúde. Em 2018, na Conferência de Astana, esse debate foi atualizado e continua atravessado por disputas. No Brasil, desde meados dos anos 1990, a Estratégia Saúde da Família (ESF) foi considerada prioritária para o reordenamento da APS, seguindo em consonância com os princípios do Sistema Único de Saúde (SUS) e orientada por uma concepção ampla do processo saúde-doença, pela valorização da ação intersetorial e pela conformação de equipes multiprofissionais com forte vinculação aos territórios, comunidades e famílias. A abrangência do modelo de atenção proposto exige competências que extrapolam os conhecimentos adquiridos em cursos de formação técnica ou na graduação. A fim de reduzir as barreiras educacionais, desde os anos 90, esforços foram empenhados para promover a qualificação na perspectiva de “educação permanente” voltadas aos profissionais no SUS, como elemento crítico para a transformação no modelo de atenção. O crescimento de programas e iniciativas educacionais orientados à atuação na APS tem sido fonte de aprendizagem e de produção de conhecimento sobre os processos de mudança nas práticas de atenção, organização e gestão no SUS. A pandemia deCovid-19 desencadeou o agravamento das desigualdades sociais e risco de piora de indicadores de saúde, colocando novas exigências para APS. O presente artigo comenta os novos imperativos para a APS e evidencia a necessidade de fortalecer os sistemas públicos de saúde por meio do enfrentamento de seus problemas estruturais, da garantia de políticas abrangentes e de investimentos que garantam a saúde como direito de todos.
