RESUMO

Onshore oil well drill cuttings and sunflower cake from biodiesel production require an appropriate destination to reduce the risks of environmental contamination. The aim of this study was to evaluate the potential use of the combination of different doses of these wastes on the growth of sunflower plants (Helianthus annus L.) and on soil chemical attributes after cultivation, making it possible to recommend safe application doses. Sunflower plants, cultivar Neon, were cultivated in a greenhouse for 80 days in Planossolo Háplico (Ultisol) as the main substrate. The design used was completely randomized, in a 6 × 6 factorial arrangement, composed of five doses of sunflower cake (2, 4, 8, 16 and 32 Mg ha-1) and five doses of drill cuttings (5, 15, 30, 45 and 60 Mg ha-1) and an experimental control using only Ultisol After cultivation, soil chemical attributes and the parameters height (H), stem diameter (D), and dry mass (DMAP) and nutrient contents in the aerial part of the plants were analyzed. Sunflower cake dose of 32 Mg ha-1 limited the germination of sunflower plants. In sunflower plants, the highest contents of calcium (Ca), magnesium (Mg), phosphorus (P) and potassium (K) were verified when the sunflower cake doses were associated with drill cuttings doses >45 Mg ha-1. The mixture between sunflower cake and drill cuttings in the proportion of 16:45 Mg ha-1, respectively, promoted higher H, D and DMAP of sunflower plants, as well as a considerable improvement in soil fertility, without causing significant increments in sodium content in the soil after cultivation.HighlightsInadequate disposal of agro-industrial wastes represents loss of raw material and energy.Drill cuttings and sunflower cake wastes enable improvements in soil fertility attributes.The combination of sunflower cake and drill cuttings contributed to sunflower growth and nutrient contents.The mixture of drill cuttings and sunflower cake has potential for use as agricultural input.

RESUMO

The assessment of risk related to medical exposures as a justification tool to assist decision-making of the medical team is not available in clinical routine. The determination of diagnostic reference levels (DRLs) for nuclear medicine (NM) procedures has been proposed as an optimization tool, but this tool has still been aimed at a standard adult individual. It is known that the activity administered, and the consequent absorbed doses in critical organs, represents the risk of a procedure being cancer induction the greatest concern, especially for young patients. Thus, the adjustment of administered activity and procedure risk to promote risk-benefit assessment is a promising tool for routine clinical use. This work aims to present a tool for determining DRLs in the administered activity related to the patient's characteristics-age group, sex, and body mass index (BMI), in order to assist the medical decision regarding the risk-benefit ratio. Thus, it is possible to assess the risk of carcinogenesis in groups of patients, considering absorbed doses in organs, cancer incidence, and mortality rates in our country. NIREA is an IT tool developed in PHP language for web environment as a friendly software. It allows the establishment of DRL and risk of cancer induced by radiation assessment through the estimation of absorbed doses in specific organs and based on the risk methodology of BEIR VII. The absorbed and effective doses were estimated based on the dose conversion factors of the radiopharmaceuticals published by the International Commission on Radiological Protection adjusted for the patient groups. Based on data from 2256 patients who underwent diagnostic procedures at National Cancer Institute between 2017 and 2019, the program was used, resulting in important information for conducting the clinical routine extracted as DRL, absorbed doses, and risk assessments, considering patient-specific data such as age, sex, and BMI. The methodology developed in this work allows NM services to keep their data available and updated regarding local DRLs, in addition to allowing the nuclear physician to know the risk of each procedure performed, extracted by individual characteristics of the patient. The affirmative is significant because the data could be used by the regulatory body of practices with ionizing radiation in Brazil to establish a reference level in Activity that has not yet existed in the country.

RESUMO

OBJECTIVES: To identify which factors are associated with cognitive frailty (CF), as well as the impact of CF on the incidence of dementia and mortality. METHODS: A systematic review with meta-analysis was carried out using papers that enrolled a total of 75,379 participants and were published up to January 2020. RESULTS: Of the 558 identified records, 28 studies met the inclusion criteria and were included in the review. The meta-analysis of cross-sectional studies showed that CF has a significant association of having an older age and a history of falls. In longitudinal studies, the analysis showed a significant increase in risk of mortality and dementia for those with CF. DISCUSSION: This is the first systematic review and meta-analysis on CF, which addressed a wide variety of factors associated with the theme and which pointed out some as a potential target for prevention or management with different interventions or treatments, showing the clinical importance of its identification in the most vulnerable and susceptible groups.

RESUMO

AIM: To estimate the incidence rates of surgical site infection and identify the independent effect of perioperative hypothermia on the incidence of this type of infection in patients undergoing abdominal surgery. BACKGROUND: Around the world, surgical site infection is a frequent complication in surgical patients, mainly causing increased morbidity and mortality rates and health service costs. DESIGN: A prospective cohort study. METHODS: The 484 patients were recruited from a large private philanthropic hospital in the state of São Paulo, Brazil, from July 2016 to May 2017. Crude and adjusted models were constructed for the hypothermia indicators to assess the effect of this exposure on surgical site infection. RESULTS: The incidence rate of surgical site infection was 20.25% (n = 98). The attributable fraction to exposed to hypothermia was >40%. A greater probability of developing surgical site infection (relative risk = 1.89) was found for patients who experienced body temperatures <36.0°C (from entry time into the operating room until the end of the surgery) for more than five hypothermic episodes or longer than 75 min. CONCLUSION: Perioperative hypothermia was an independent risk factor for surgical site infection. SUMMARY STATEMENT: What is already known about this topic? Around the world, surgical site infection is a complication that leads to damage to the patient and increased costs for the health services. Despite recent advances in surgical techniques, surgical site infection remains one of the most frequent complications in abdominal surgery. Perioperative hypothermia can increase the incidence rates of surgical site infection. There is evidence that perioperative hypothermia is associated with surgical site infection in abdominal surgery, but most studies were conducted in developed countries using retrospective designs. What this paper adds? Perioperative hypothermia was identified as an independent risk factor for surgical site infection in patients undergoing abdominal surgery. The attributable fraction to the exposed indicated that, if the main exposure of interest (perioperative hypothermia) could be prevented during surgical anaesthetic procedures, more than 40% of surgical site infection cases would be avoided. The classification of the American Society of Anaesthesiologists was independently associated with the surgical site infection and presented a dose-response effect among its categories. Spinal anaesthesia served as an independent protective factor for surgical site infection. The implications of this paper: The health service managers need to be aware of potential cost-savings associated with perioperative hypothermia prevention as a measure to reduce the incidence of surgical site infection. During the perioperative period, health professionals need to implement effective measures to maintain patients' normothermia, promoting improved care and surgical patient safety. In this context, the nurse's role is fundamental. Future research projects using a prospective design and developed to address the reality of developing countries can contribute to the strengthening and consistency of the findings with a view to a global understanding of the surgical site infection problem.

RESUMO

BACKGROUND: Surgical site infection (SSI) remains one of the most frequent complications in abdominal surgery, and hyperglycemia prevention is recommended as a measure to reduce this type of infection. The aims of this study were to estimate the incidence of SSI and to identify the effect of perioperative hyperglycemia on the incidence of this type of infection in patients undergoing abdominal surgery. METHODS: We enrolled 484 abdominal surgery patients ≥ 18 years of age, recruited between July 2016 and May 2017. Data were collected through structured interviews and patient assessments in the perioperative period and at the surgical outpatient clinic (30th day after surgery). Crude and adjusted models were built to identify the effect of hyperglycemia on SSI. RESULTS: The incidence rate of SSI was 20.25%. The attributable fraction for patients exposed to hyperglycemia was >60%. In the multivariable analysis, patients with hyperglycemia, at the end of the surgery and 12 hours later, were more likely to develop this type of infection (relative risk = 1.89 and 2.17, respectively). CONCLUSIONS: Perioperative hyperglycemia was identified as an independent risk factor for SSI. The evidence generated reinforces the importance of proper glycemic control management in the perioperative period for the prevention of SSI.

RESUMO

A infecção de sítio cirúrgico (ISC) é uma complicação frequente que pode acometer o paciente submetido ao procedimento anestésico cirúrgico, acarretando o aumento da morbidade, mortalidade e dos custos hospitalares, bem como do sofrimento emocional e físico do paciente. Este estudo teve como objetivos estimar a incidência de ISC em pacientes submetidos à cirurgia abdominal, identificar as taxas de ISC segundo fatores relacionados ao paciente, ao procedimento anestésico cirúrgico e ao ambiente da sala cirúrgica, identificar os fatores de risco e de proteção, e identificar o efeito independente da hipotermia sobre a incidência de ISC. Para o alcance dos objetivos propostos, conduziu-se estudo de coorte com 484 pacientes submetidos à cirurgia abdominal. Para a coleta de dados elaborou-se instrumento, submetido à validação aparente e de conteúdo por cinco juízes. A coleta de dados foi realizada na unidade de internação ou na sala de recepção do centro cirúrgico, no período intraoperatório, no período de internação e reinternação, e no retorno no 30° dia após a cirurgia. A hipotermia foi avaliada a partir de três mensurações distintas, a saber: 1 - temperatura Delta; 2 - número de vezes em que a temperatura do paciente foi <36,0°C; 3 - tempo de exposição, em minutos, em que o paciente esteve submetido a temperaturas <36,0°C. A incidência bruta de ISC foi de 20,25% (98 casos). A incidência de ISC apresentou maior magnitude nos participantes do sexo feminino (22,43%), nos pacientes na faixa etária de 60 anos e mais (27,22%), e com obesidade classe II (25,71%). As médias de duração da anestesia e da cirurgia foram maiores no grupo com ISC, a incidência de ISC apresentou maior magnitude naqueles pacientes submetidos a cirurgias de porte III (85,71%) e anestesia combinada (41,10%). A incidência de ISC apresentou maior magnitude naquele participante que no final da cirurgia estava exposto à temperatura da sala de operação < 20°C (33,33%), e naqueles expostos à umidade do ar entre 45-55 kg/m3 (22,18%). Na mensuração 1 (modelo final), a hipotermia não apresentou relação causal com a ISC, e as variáveis classificação ASA, porte cirúrgico e tipo de anestesia permaneceram independentemente associadas à ISC. Na mensuração 2 (modelo final), identificou-se o efeito causal independente da hipotermia sobre a ISC, os pacientes que estiveram submetidos mais de cinco vezes a temperaturas <36,0°C apresentaram maior probabilidade (89%; RR=1,89) de desenvolverem ISC, as variáveis classificação ASA e tipo de anestesia mantiveram-se independentemente associadas à ISC. Na mensuração 3 (modelo final), também identificou-se o efeito causal independente da hipotermia sobre a ISC, os pacientes que estiveram submetidos a mais de 75 minutos a temperaturas <36,0°C apresentaram maior probabilidade (89%; RR=1,89) de desenvolverem ISC, as variáveis classificação ASA e tipo de anestesia permaneceram independentemente associadas à ISC. A raquianestesia foi fator de proteção independente para ISC, nos três modelos finais. Os resultados evidenciados poderão subsidiar a tomada de decisão dos profissionais de saúde na implementação de ações direcionadas para a prevenção e controle de ISC, com ênfase em medidas para a prevenção da hipotermia perioperatória

Surgical site infection (SSI) is a frequent complication that can affect the patient undergoing surgical anesthetic procedure, leading to increased morbidity, mortality and hospital costs, as well as emotional and physical suffering of the patient. This study aimed to estimate the incidence of SSI in patients undergoing abdominal surgery; to identify SSI rates according to factors related to the patient, to the surgical anesthetic procedure and to the operating room environment; to identify risk and protective factors; and to identify the independent effect of hypothermia on the incidence of SSI. To reach the proposed objectives, a cohort study was conducted with 484 patients undergoing abdominal surgery. An instrument was developed for data collection, and submitted to face and content validation by five judges. Data collection was performed in the inpatient care unit or in the surgical center reception room, during the intraoperative period, the hospitalization and readmission period, and on the 30th postoperative day. Hypothermia was evaluated from three different measurements: 1) delta temperature; 2) number of times the patient temperature was <36.0°C; 3) exposure time, in minutes, in which the patient was submitted to temperatures <36.0°C. The crude incidence of SSI was 20.25% (98 cases). The incidence of SSI presented higher magnitude in female participants (22.43%), in patients aged 60 years and over (27.22%), and with class II obesity (25.71%). The mean duration of anesthesia and surgery were higher in the SSI group, the SSI incidence was higher in patients undergoing surgery III (85.71%) and combined anesthesia (41.10%). The incidence of SSI presented higher magnitude in participants who were exposed, in the end of surgery, to temperature <20°C (33.33%) at the operating room; and in those exposed to air humidity between 45-55 kg/m3 (22, 18%). In the measurement 1 (final model), hypothermia did not present a causal relationship with SSI, and the variables ASA classification, surgical size and type of anesthesia remained independently associated with SSI. In the measurement 2 (final model), the independent causal effect of hypothermia on SSI was identified; patients who were submitted more than five times to temperatures <36.0°C were more likely (89%; RR=1.89) to develop SSI, the variables ASA classification and type of anesthesia remained independently associated with SSI. In the measurement 3 (final model), the independent causal effect of hypothermia on SSI was also identified; patients who were submitted to more than 75 minutes to temperatures <36.0°C were more likely (89%; RR = 1.89) to develop SSI, the variables ASA classification and type of anesthesia remained independently associated with SSI. Spinal anesthesia was an independent protective factor for SSI in the three final models. The found results may support the decision-making of health professionals in the implementation of actions directed to the prevention and control of SSI, with emphasis on measures for the prevention of perioperative hypothermia

RESUMO

Objetivo Analisar os fatores de risco de infecção da ferida operatória em neurocirurgia. Métodos Estudo transversal, prospectivo, conduzido em hospital de nível terciário com 85 neurocirurgias eletivas e limpas, tendo como desfecho a infecção até 30 dias após o procedimento cirúrgico. Resultados A ocorrência de infecção de sítio cirúrgico foi de 9,4% (n=8). Na análise bivariada observou-se que os fatores de risco: tempo total de internação, Índice de Massa Corporal, porte cirúrgico e transfusão sanguínea foram associados com a presença de infecção. Após ajuste no modelo de regressão logística binária, apenas o tempo total de internação mostrou relação estatisticamente significativa com a presença de infecção. Conclusão A ocorrência de infecção de sítio cirúrgico em neurocirurgia na instituição estudada foi maior do que o preconizado na literatura científica. Os resultados apontaram que o acompanhamento ambulatorial do paciente cirúrgico após a alta hospitalar pode reduzir a subnotificação dos casos de infecção...

Objective To analyze risk factors for surgery site infection in neurosurgery. Methods A prospective cross-sectional study conducted in a tertiary hospital analyzing 85 elective and clean neurosurgeries with an outcome of infection within 30 days after surgery. Results Surgical site infection occurred in 9.4% (n=8) of cases. Bivariate analysis revealed that the following risk factors were associated with the presence of infection: total length of hospital stay, Body Mass Index, surgical size and blood transfusion. After running binary logistic regression adjustments, only the total length of hospital stay was significantly related to the presence of infection. Conclusion The occurrence of surgical site infection in neurosurgery in the studied institution was higher than recommended by the scientific literature. The results show that outpatient follow up of patients who undergo surgery after hospital discharge may reduce the underreporting of infection cases...
