Strategy for the development of agricultural machinery : importance of patent analysis

During the product development, patents help identify new project opportunities and, if well analyzed, can reveal technical strategies in terms of how countries, companies, and universities link patents and product development. In the context of the agricultural machinery sector there is a complexity in the integration of data from patents with the stages of development conceptions. In this context, the article aims to present how the information obtained from a patent bank can be used for the development of agricultural machinery. As a methodology, the Systematic Bibliographic Review was selected to identify and relate strategies that add value throughout the agricultural machinery project. As a result, research has shown that the use of patent information can assist in the development of agricultural machinery from technical data. In addition, patents are characterized as a valuable source of technological information, as it is inexpensive and capable of feeding a company in its own research activity and in the development of new products. It is concluded that the information from patents, suggested as strategies in the model of agricultural machinery development, allows for managerial and technical decisions aimed at improving products. Finally, the research contributed to fill the information gap between patents and the development of agricultural machinery, a diffusion of data that, if well connected, can promote a competitive differential in companies

The proposition of factors for analysis of the maintenance of agricultural tractors from a systematic bibliographic review

The maintenance of agricultural tractors can be understood as the set of procedures that seek to keep the equipment in the best working conditions. However, carrying out adequate planning that can help optimize the maintenance of agricultural tractors is a complex task. The article consists of identifying and presenting a proposal of analysis factors for the maintenance of agricultural tractors, as well as their technical characteristics and modes of operation. In methodological terms, a Systematic Bibliographic Review was applied on maintenance and planning for agricultural tractors in two international databases. The research is classified as descriptive and comparative, of an exploratory nature. As a result, the study contributed to the information gap regarding the maintenance of agricultural tractors. In addition, we identified the main factors that must be analyzed to keep the equipment in the best operating conditions and that are responsible for increasing its useful life and avoiding future problems. The maintenance factor, which includes checking the level and oil change of the front axle, is characterized as the most important analysis procedure

High triglyceride to HDL-cholesterol ratio as a biochemical marker of severe outcomes in COVID-19 patients

Background & aims Coronavirus disease 2019 (COVID-19) patients with severe complications have shown comorbidities with cardiovascular-disease, hypertension and type 2 diabetes mellitus; clinical disorders that share the common metabolic alterations of insulin resistance and dyslipidaemia. A high triglyceride to high density lipoprotein cholesterol (Tg/HDL c) ratio has been associated with reduced insulin sensitivity, metabolic syndrome and adverse cardiovascular events. Our aim in this study was to determine the association between different components of the lipid profile and particularly the Tg/HDL c ratio with severe complications like the requirement of invasive mechanical ventilation in COVID-19 patients. Methods We collected demographic, clinical and biochemical data to conduct a cohort study in 43 adult patients with confirmed COVID-19 diagnosis by quantitative polymerase chain reaction (qPCR) at baseline and in the subsequent 15 days. Patients were subjected to a very similar treatment scheme with the JAK1/2 inhibitor ruxolitinib. Descriptive statistics, variable association and logistic regression were applied to identify predictors of disease severity among elements and calculations from the lipid profile. Results Patients were aged 57 ± 14 years; 55.8% were male from which 75% required hospitalization and 44.2% were female who 58% were hospitalized. The most common comorbidities were type 2 diabetes mellitus (58%) and hypertension (40%). Hospitalized and critical care patients showed lower HDL c blood levels and increased Tg/HDL c ratio than those with outpatient management and mild/asymptomatic COVID-19. Tg/HDL c ratio correlated with variables of disease severity such as lactate dehydrogenase (LDH) levels (r = 0.356; p < 0.05); National Early Warning Score 2 (NEWS 2) (r = 0.495; p < 0.01); quick sequential organ failure assessment (qSOFA) (r = 0.538; p < 0.001); increased need of oxygen support (r = 0.447; p < 0.01) and requirement of mechanical ventilation (r = 0.378; p < 0.05). Tg/HDL c ratio had a negative correlation with partial oxygen saturation/fraction of inspired oxygen (SaO 2/FiO2) ratio (r = −0.332;p < 0.05). Linear regression analysis showed that Tg/HDL c ratio can predict increases in inflammatory factors like LDH (p < 0.01); ferritin (p < 0.01) and D-dimer (p < 0.001). Logistic regression model indicated that ≥7.45 Tg/HDL c ratio predicts requirement of invasive mechanical ventilation (OR 11.815, CI 1.832–76.186, p < 0.01). Conclusions The Tg/HDLc ratio can be used as an early biochemical marker of COVID-19 severe prognosis with requirement of invasive mechanical ventilation

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
