O algoritmo digital permitiu o manejo de dados dos usuários da web pelos conglomerados informacionais. De forma discreta e personalizada, a nova forma de governamentalidade coleta, organiza, permuta ...e devolve os dados ao próprio indivíduo na forma de mais informações. Cada vez mais, esbarra na dimensão singular, tocando o campo do gozo via proliferação de objetos a que, na teoria lacaniana dos discursos, assume a dupla função de perda e de incessante tentativa de suplementação de gozo. Com o incremento informacional, o objeto chega ao ápice social e o digital alcança patamar discursivo. Inserindo-se no mesmo nicho do saber, a informação digital se aproveita da divisão subjetiva, deixando pouco espaço para que o sujeito possa lidar com a entropia de seu gozo via desejo. Se a neguentropia é o atributo do saber que limita a dispersão de gozo, na informação tratada e retornada algoritmicamente tal processo sofre uma aceleração, agindo diretamente sobre a economia dos afetos. Com prejuízo para o sujeito, resta uma experiência de gozo cada vez mais direta, crua, menos mediatizada pelo saber e pelo Outro.
Mangrove forests provide essential ecosystem services to human communities, including climate regulation. In Brazil, the National System of Nature Conservation Units divides Protected Areas (PAs) ...into two categories: Full Protection (FP) and Sustainable Use (SU). The FP areas are composed of five categories, including National Parks, and the SU areas comprise seven categories, such as Environmental Protection Areas. The current research compared climatic attributes, leaf area index, and vegetation structure development in mangrove forests in two distinct categories of PAs (FP and SU) along the southern coast of the state of São Paulo (Brazil) to analyze the climatic conditions in different PA categories. A survey of the microclimatic attributes found that the conserved mangroves in the FP PA presented a) greater thermal stability in terms of the maximum, minimum, and mean air temperatures, and b) a better role of mangrove vegetation in (re)distributing the energy inside the forest. Therefore, it is affirmed that FP PAs play a fundamental role in maintaining the good conservation status of mangroves and, consequently, stabilizing the microclimate.
•Nurses, doctors, healthcare workers, and other medical professionals who are testing for and treating patients with COVID-19 are at a higher risk of contracting it than the general public.•The ...combination of stress and possible exposure puts healthcare professionals, from physicians and nurses, to specialists, at greater risk of contracting COVID-19 and potentially spreading it to others.•Health professionals directly involved in the diagnosis, treatment, and care of patients with COVID-19 develop the insertion of psychic spaces for the installation of pain and psychological suffering and other mental health symptoms.•The foreseeable shortage of supplies and an increasing flow of suspected and real cases of COVID-19 contribute to the pressures and concerns of health professionals.
: The fact that COVID-19 is transmissible from human to human and associated with high morbidity and potentially fatality can intensify the perception of personal danger. In addition, the foreseeable shortage of supplies and an increasing flow of suspected and real cases of COVID-19 contribute to the pressures and concerns of health professionals.
: The studies were identified in well-known international journals found in two electronic databases: Scopus and Embase. The data were cross-checked with information from the main international newspapers.
: Work-related stress is a potential cause of concern for health professionals. It has been associated with anxiety including multiple clinical activities, depression in the face of the coexistence of countless deaths, long work shifts with the most diverse unknowns and demands in the treatment with patients with COVID-19. Therefore, it is an important indicator of psychic exhaustion.
: As coronavirus cases increase and deaths surge in Italy, new figures show an "enormous" level of contagion among the country's medical personnel. At least 2,629 health workers have been infected with coronavirus since the outbreak onset in February, representing 8.3% of total cases. The percentage of infected health workers has almost doubled the number registered in China throughout the epidemic. Intensive care unit physicians are on their stress limit, especially when dealing with older patients and with death prospects. Doctors, not a relative, are inevitably the last people a dying COVID-19 patient will see.
Objective: The moderators of Pilates training on balance and posture in older individuals are unclear. We investigated through meta-analysis the effectiveness of Pilates to improve the balance and ...posture of older individuals and examine potential moderators of those effects. Methods: Electronic databases were searched by multiple reviewers until September 30th, 2021 to locate articles published in English, Spanish or Portuguese. Qualifying trials included adults aged ≥60 y and measured static/dynamic balance or posture pre-post intervention. Data on study design, sample characteristics, and features of Pilates interventions were tested as moderators of balance and posture outcomes. Results: Twenty-seven trials included 1,017 individuals (69.2 ± 4.7 y). Overall, sessions of 58.2 ± 8.6 min were performed 2.1 ± 0.5 d/wk for 12.3 ± 9.7 wk. Information on loads was often imprecise. The effect sizes (ES) in controlled vs. uncontrolled trials were: static balance (k = 13, ES 0.270, 95% confidence interval CI 0.182–0.358 vs. k = 4, ES 0.284, CI 0.155–0.413); dynamic balance (k = 14, ES 0.714, CI 0.428–1.000 vs. k = 4, ES 0.648, CI (-0.008–1.303); posture (k = 2; ES 0.311, CI -0.106–0.729 vs. k = 5, ES 0.349, CI 0.240–0.458). Trials with lower methodological quality as reflected by the median of TESTEX inventory produced greater ES for dynamic balance (ES 0.928 vs. 0.523; p < 0.05). Greater training volumes (duration x number of sessions) increased ES of dynamic balance (ES 0.743 vs. 0.715) and posture (ES 0.422 vs. 0.176), the opposite occurring for static balance (ES 0.237 vs. 0.405) (p < 0.05). Conclusions: Pilates seems to improve static and dynamic balance in older adults, while data on posture are less convincing. Poor study quality may overestimate the effects on dynamic balance. Greater training volumes appear to favor improvements in dynamic balance and posture.
•Insufficient housing quality is associated with stress and mental health impacts.•Homeless organizations have been sounding the alarm for weeks. They have been warning that the coronavirus could ...cause catastrophic harm to unhoused communities amid the absence of a coordinated strategy to aid people already struggling to survive in tents and overcrowded shelters.•Depression and stress weaken our immune systems. Individuals with low incomes are disproportionately likely to suffer from poor mental health. As the coronavirus continues to unleash mayhem, we could be on an economic precipice.
Insufficient housing quality is associated with stress and mental health impacts. Crowding, pollution, noise, inadequate lighting, lack of access to green spaces, and other environmental factors associated with slums can exacerbate mental health disorders, including depression, anxiety, violence, and other forms of social dysfunction.
The studies were identified using large-sized newspapers with international circulation.
Experts say that people who sleep in shelters or on the streets already have lower life expectancy, suffer from addiction, and have underlying health conditions that put them at greater risk should they develop the virus. There are just so many competing and unmet needs, which makes it much harder for homeless to contend with all of this. If exposed, people experiencing homelessness might be more susceptible to illness or death due to the prevalence of underlying physical and mental medical conditions and a lack of reliable and affordable health care. Nevertheless, without an urgent solution, people experiencing homelessness will remain in limbo.
Many people living on the streets already have a diminished health condition, higher rates of chronic illnesses or compromised immune systems, all of which are risk factors for developing a more serious manifestation of the coronavirus infection. Those suffering from mental illness may have difficulty in recognizing and responding to the threat of infection. Homeless people have less access to health care providers who could otherwise order diagnostic testing and, if confirmed, isolate them from others in coordination with local health departments.
Abstract Introduction: Little research has been done on the effects of muscle-resistance training (RT) in hypertensive older adults. Objective: The aim of this meta-analysis was to verify the ...efficacy of RT, on a chronic basis, on the systolic (SBP) and diastolic blood pressure (DBP) of hypertensive older adults. Method: Several literature databases were explored to find studies on controlled and randomized trials that evaluated the effects of RT in hypertensive older adults for more than 10 weeks. Profile of the participants, sample size, intervention protocol, and results of SBP and DBP were analyzed. The PEDro scale and the Cochrane tool were used to analyze the methodological quality of the studies and the risk of bias, respectively. The RevMan5.3 program was used to analyze the results on the SBP and DBP after the RT intervention and in the control groups. Results: The meta-analysis of five studies considering 96 hypertensive individuals who underwent RT and 104 hypertensive control subjects showed that the regular practice of RT from 12 to 16 weeks, three times a week, with three sets from 8 to 12 repetitions at an intensity of 60% to 80% of one-repetition maximum (1-RM), significantly reduced SBP by 7.26 mmHg (95%CI = -9.16 - 5.37) and DBP by 4.84 mmHg (95%CI = -5.89 - 3.79). Conclusion: The muscle-resistance training was effective in reducing, chronically, the blood pressure of hypertensive older adults. It can also decrease the need for medication inherent to hypertension.
Resumen Introducción: Poca investigación se realizó sobre los efectos del entrenamiento de resistencia muscular (ER) en adultos mayores hipertensos. Objectivo: El objetivo del presente metanálisis fue verificar la eficacia del ET, de forma crónica, en la presión arterial sistólica (PAS) y diastólica (PAD) de ancianos con hipertensión controlada. Método: Varias bases de datos de la literatura se exploraron para encontrar estudios que examinaron ensayos clínicos controlados y aleatorizados que evaluaron los efectos del ER en ancianos hipertensos por un período de más de 10 semanas. Se analizó el perfil de los participantes, el tamaño de la muestra, el protocolo de intervención y los resultados de la PAS y PAD. La Escala PEDro y la herramienta Cochrane se utilizaron para analizar la calidad metodológica de los estudios y el riesgo de sesgos, respectivamente. El programa RevMan5.3 fue utilizado para analizar los resultados en la PAS y PAD después de la intervención ER y en los grupos de control. Resultados: El metanálisis de cinco estudios incluyó que, considerando los 96 individuos hipertensos sometidos a ET y 104 sujetos de control hipertensos, la práctica regular de ET por 12 a 16 semanas, tres veces por semana, con tres series de 8 a 12 repeticiones en una intensidad del 60% al 80% de una repetición máxima (1-RM), redujo significativamente la PAS en 7,26 mmHg (IC 95% = -9,16 - 5,37) y DBP por 4,84 mmHg (IC 95% = -5,89 - 3,79). Conclusión: El entrenamiento resistido muscular fue eficaz en la reducción de la presión arterial de ancianos hipertensos controlados, crónicamente, y puede disminuir la necesidad de medicación antihipertensiva.

Estes resultados implicam uma maior sobrevivência para esta população, bem como uma possível diminuição da necessidade de medicamentos inerentes à hipertensão.
Abstract
A mangrove is a transitional coastal ecosystem between marine and terrestrial environments that is characterized by salinity and constant tidal flooding. Mangroves contain plant communities ...that are adapted to several physical constraints, including the climate. The purpose of this study was to analyze the variations in climatic attributes (air temperature, relative air humidity, global solar radiation, wind, and rainfall) in the mangroves located in the municipality of Iguape, on the southern coast of the state of São Paulo, Brazil. In addition, it was determined whether the existing variation is related to the presence of the canopy environment. A microclimate tower was installed with two weather stations to obtain an analysis of the variation of the climatic attributes above and below the canopy. The results indicate that global solar radiation had an average transmissivity of 26.8%. The air temperature at 10 m was higher than that at the sensor at 2 m. The average rainfall interception for the mangrove environment was 19.6%. Both the maximum gust and average wind speed decreased by approximately 63.7% at 2 m. The mangrove canopy was found to be an important control on the variation of climatic attributes. On a microclimatic scale, the climate attributes had a direct influence on the spatial distribution of vegetation. Additionally, characteristics of the canopy are the main control for this variation, especially for the distribution of rainfall and the amount of solar radiation below the canopy, which influence the distribution of plant species in the environment.
The elderly population in Brazil is on the rise. As a consequence, there is an equal growth in the number of free public exercise programs directed to this group. Considering the benefits of ...exercising and the importance of adherence to this behavior so that the benefits can be perceived, we conducted a systematic review of the existing literature on the topic, aiming to identify the reasons that lead to adherence to free public exercise programs, as well as those that lead to abandoning the same programs. Searches were conducted on SciElo, SPORTdiscus and Pubmed databases, with search phrases in Portuguese and in English. After a triage, ten studies were analyzed regarding sample characteristics, program type, data collection method and the reasons behind the subjects’ adherence and abandonment. We verified that elderly people tend to enter the projects for health-related reasons, but they remain due to other factors, such as socialization and the perception of the benefits brought on by exercising. As for abandonment, it occurs due to health problems, muscle pain due to exercising, dislike for the classes and family business.

O presente trabalho decorre de hipótese de que a partir das mudanças culturais introduzidas pelos processos de digitalização da informação, tornou-se possível observarmos, na sociedade contemporânea, ...uma mutação no estatuto do saber, o que teve efeitos para a própria subjetividade. Partindo do matema do discurso do capitalista proposto por Jacques Lacan, assinalamos os elementos que caracterizam o novo padrão discursivo em curso na cultura digital em função de sua dinâmica animada pela lógica dos números, a ser nomeado como discurso digital. Buscaremos apontar em que medida é a mudança de estatuto do saber que nos permite inferir esta nova dinâmica discursiva. Assim, será feito um delineamento do que seja a cultura digital, indicada como efeito do novo formato assumido pelo capitalismo. Na sequência, serão traçadas as perspectivas assumidas pela noção de saber no âmbito do discurso capitalista. Finalmente, serão consideradas as mutações sofridas pela sociedade contemporânea com a entrada em cena da informação digitalizada e, mais especificamente do algoritmo digital, de modo a propor a emergência do discurso digital como sendo a mais recente versão do discurso capitalista. A partir de tais premissas, cabe indagar se estaríamos ainda diante do discurso do capitalista ou, de fato, de um novo discurso em que os elementos do laço social recebessem rearranjo inédito, isto é, um sexto discurso, nomeadamente, discurso digital.
With the increase in life expectancy, it is important to acknowledge the impact of health promotion programs on the elderly. The aimed of this study was to evaluate the influence of the Rio de ...Janeiro Ar Livre physical program on the functional autonomy of octogenarian elderly women´s. To this end, elderly women´s from 19 Rio de Janeiro Ar Livre program gyms were selected for the experimental group (EG) (n=23; 82.57±3.78 years), and for the Control Group (CG) (n=17; 82.88±2.23 years) from the attending cohabitation houses of the City of Rio de Janeiro. To access the functional autonomy was used Rikli and Jones (1999) protocol in two times separated by (28 weeks). It was observed in the EG a significant (p=0.010) increase in Upper limbs' strength test (13.00±3.41 to 15.09±3.60 times, pre and post innervation, respectively) and a significant (p=0.002) increase in 2 minutes Step test in the CG (36.59±15.00 to 47.24±10.96 times, pre and post, respectively). However, any significant differences between groups were observed in all variables analysed. Based in the present data we can conclude that the training program was only effective in the promotions of the functional strength of the upper limbs and to maintain the functional autonomy of octogenarian elderly women.
