title: Lower back pain and level of disability amongst construction workers

description: Abstract Introduction: Lower back pain is a symptom that significantly affects people's lives, especially workers whose professional achievements can be limited by this pain. Objective: Estimate prevalence of lower back pain and describe the levels of disability amongst construction workers. Methods: 84 construction workers participated in this study. Each of them was given three questionnaires. The first questionnaire was aimed at identifying sociodemographic variables such as work and lifestyle habits. The second questionnaire was created by Monnerat and Pereira to measure the intensity of lower back pain. The last questionnaire was created by Roland-Morris to measure functional incapacity. The SPSS 18.0 program was used for data analysis. Lower back pain was described with the Mann Whitney U test using the variables of both labor and time. Furthermore, a correlation between lower back pain intensity and functional incapacity was found by Spearman. Results: A higher prevalence of lower back pain was found (71.4%) amongst the construction workers especially during laborious activity. Time worked did not affect the prevalence of lower back pain nor did it lead to functional incapacity in workers. Conclusion: Based on all observed data, it was concluded that strenuous labor activity amongst the populace drove lower back pain prevalence.

title: Effect of hydraulic retention time on chemical oxygen demand and total nitrogen removal in intermittently aerated constructed wetlands

description: Abstract This study evaluated the effect of hydraulic retention time on chemical oxygen demand (COD) and total nitrogen (TN) removal in an intermittently aerated constructed wetlands. Two horizontal subsurface-flow constructed wetlands were used: one without aeration and the other aerated intermittently (1 hour with aeration/7 hours without aeration). Both systems were evaluated treating domestic wastewater produced synthetically. The flow rate into the two CWs was 8.6 L day-1 having a hydraulic retention time of 3 days. The results show that the intermittently aerated constructed wetland were highly efficient in removing COD (98.25%), TN (83.60%) and total phosphorus (78.10%), while the non-aerated constructed wetland showed lower efficiencies in the removal of COD (93.89%), TN (48.60%) and total phosphorus (58.66). These results indicate, therefore, that intermittent aeration allows the simultaneous occurrence of nitrification and denitrification processes, improving the removal of TN in horizontal subsurface-flow constructed wetlands. In addition, the use of intermittent aeration also improves the performance of constructed wetlands in removing COD and total phosphorus.

title: Dose-response of neuromuscular and anaerobic performance to whole-body vibration

description: Abstract Aims: The present study was designed to investigate the dose-response relationship of muscular performance and anaerobic power to whole-body vibration (WBV). Methods: Nine recreationally males were subjected to five experimental conditions: A) Squat exercise (SE) without WBV; B) WBV1 [31.55 m.s-2]; C) WBV2 [159.73 m.s-2]; (D) WBV3 [319.45 m.s-2]; and E) WBV4 [567.91 m.s-2]. Before and after the experimental procedures, muscle performance was assessed by a vertical jump test and handgrip strength test and anaerobic power by Wingate anaerobic test (WT). Results: WBV2 and WBV3 increased jump relative power [Δ=0.92 ± 0.89 W/Kg (+1.97%) and Δ=1.29 ±1.79 W/Kg (+2.77%), respectively; P=0.02; effect size= 0.92; power= 0.87] and height [Δ=0.96 ± 0.73 cm (2.80%) and Δ=1.61 ± 2.36 cm (4,57%), respectively; P= &lt; 0.01; effect size= 0.96; power= 0.99] compared to the SE [Δ=-1.28 ± 0.81 cm (-3.55%)]. There was no dose-response relationship of handgrip strength to WBV. WBV2 improved WT relative power (power/body weight) compared to the other experimental conditions [Δ= 0.61 ± 0.36 W/Kg (+ 5.25%); P &lt; 0.01; ; effect size= 0.98; power= 0.99], and WT relative work was higher in WBV3 [Δ= 1.86 ± 5.46 KJ/Kg (+ 0.70%)condition compared to WBV1[Δ= -6.71 ± 4.03 KJ/Kg (- 2.49%) ( P= 0.03). Conclusion: These results suggest that lower limb muscular performance and anaerobic power are responsive to vibration accelerations WBV2 (159.73 m.s-2) and WBV3 (319.45 m.s-2).

title: Soil clay content [%] for continental Europe at 30 m spatial resolution for period 2000-2020: Open Soil Data Cube for Europe

description: Predictions are based on the 3D Ensemble Machine Learning framework, as implemented in the R environment for statistical computing (Hengl & MacMillan, 2019; Hengl, et al., 2021). For each pixel we provide prediction errors as 1 standard deviation in either log or the original variable scale. The short description of currently available soil properties: clay.tot = clay content [percent]; Soil properties were predicted at fixed depths: Surface soil = s0..0cm,<br> Subsoil 1 = s30..30cm,<br> Subsoil 2 = s60..60cm,<br> Subsoil 3 = s100..100cm. To produce estimates for depth intervals e.g. 0–30 cm, 0–100 cm best use the trapezoidal rule formula. Periods: 2000 (2000–2003), 2004 (2004–2007), 2008 (2008–2011), 2012 (2012–2015), 2016 (2016–2019), 2020;

title: Use of organic fertilization with irrigation in coffee production in brazilian cerrado

description: Abstract Coffee irrigation has increased in the main Brazilian coffee regions. However, in recent years, with climate change, years with water deficits greater than 150 mm have been observed, affecting the vegetative and productive development of the crop and also the replenishment of surface and underground springs. One practice that increases soil water retention capacity is organic fertilization. This work evaluated different combinations of irrigation and organic fertilization on the yield and quality of coffee produced in the Minas Gerais cerrado region. The treatments were: T1: total irrigation; T2: no irrigation; T3: total irrigation + organic fertilization (chicken manure, 10 ton ha-1); T4: no irrigation + organic fertilization (chicken manure, 10 ton ha-1); T5: 50% irrigation + organic fertilization (chicken manure, 10 ton ha-1). After 7 harvests, it was concluded that the treatment that combined organic fertilization with application of half of the necessary irrigation presented the best yield, superior to the treatment with total irrigation and exclusively mineral nutrition.

title: MINIMALLY INVASIVE SPINE SURGERY IN THE NUEVO HOSPITAL CIVIL DE GUADALAJARA "DR. JUAN I. MENCHACA"

description: ABSTRACT Objective: To describe our experience on a case series treated with minimal invasive techniques in spine surgery, with short-term follow-up and identify complications. Methods: A prospective analysis was performed on 116 patients operated on by the same team from September 2015 to June 2016. Evaluating the short-term follow-up we registered the surgical time, bleeding, complications, hospital stay, pre- and postoperatively neurological status, as well as scales of disability and quality of life. Demographic and surgical procedure data were analyzed with SPSS version 20 program. Results: A total of 116 patients with a mean age of 49.7 + 15.7 (21-85 years) underwent surgery being 76 (65%) with lumbar conditions and 37 (32%) with cervical conditions. The most common procedures were tubular discectomies (31), tubular bilateral decompression (17), lumbar MI-TLIFs (7), and anterior cervical discectomy and fusion (35). The mean blood loss was 50.6 cc, the hospital stay was 1.7 day, pre- and postoperative pain VAS were 7.4 % and 2.3%, respectively, pre- and postoperative Oswestry (ODI) were 64.6% and 13.1%, respectively, pre- and postoperative SF-36 of 37.8% and 90.3%. There were no major complications, except for a surgical wound infection in diabetic patient and three incidental durotomies, one of these being a contained fistula, treated conservatively. Conclusions: The current tendency towards minimally invasive surgery has been justified on multiple studies in neoplastic and degenerative diseases, with the preservation of the structures that support the spine biomechanics. The benefits should not replace the primary objectives of surgery and its usefulness depends on the skills of the surgeon, pathology and the adequate selection of the techniques. We found that the tubular access allows developing techniques such as discectomy, corpectomy and fusion without limiting exposure, avoiding manipulation of adjacent structures, reducing complications and being feasible in a public hospital.

title: Assessment of trauma scoring systems in patients subjected to exploratory laparotomy

description: ABSTRACT Objective: to assess the epidemiological profile of patients undergoing exploratory trauma laparotomy based on severity and prognosis criteria, and to determine the predictive accuracy of trauma scoring systems in terms of morbidity and mortality. Methods: retrospective cohort study and review of medical records of patients undergoing exploratory laparotomy for blunt or penetrating trauma at the Hospital de Pronto Socorro de Porto Alegre, from November 2015 to November 2019. Demographic data, mechanism of injury, associated injuries, physiological (RTS and Shock Index), anatomical (ISS, NISS and ATI) and combined (TRISS and NTRISS) trauma scores, intraoperative findings, postoperative complications, length of stay and outcomes. Results: 506 patients were included in the analysis. The mean age was 31 ± 13 years, with the majority being males (91.3%). Penetrating trauma was the most common mechanism of injury (86.2%), predominantly by firearms. The average RTS at hospital admission was 7.5 ± 0.7. The mean ISS and NISS was 16.5 ± 10.1 and 22.3 ± 13.6, respectively. The probability of survival estimated by TRISS was 95.5%, and by NTRISS 93%. The incidence of postoperative complications was 39.7% and the overall mortality was 12.8%. The most accurate score for predicting mortality was the NTRISS (88.5%), followed by TRISS, NISS and ISS. Conclusion: the study confirms the applicability of trauma scores in the studied population. The NTRISS seems to be the best predictor of morbidity and mortality.

title: Seasonal variation in essential oil content and chemical profile of mint in southeast of Brazil

description: ABSTRACT: This study evaluated the influence of seasonality in essential oil (EO) chemical composition of Mentha x piperita L. and Mentha viridis L. grown in southeast of Brazil. Leaves were collected from November 2011 until August 2013, in the middle of the following seasons: Spring (November), Summer (February), Autumn (May) and Winter (August). EO extraction was carried out by hydrodistillation in Clevenger apparatus for 1 hour. Chemical composition of EO was analyzed by GC-FID and GC-MS. The EO content and its chemical composition were influenced by seasonality in both species. The highest EO content was obtained for M. x piperita during spring (4.26%) and for M. viridis during spring (3.30%) and summer (3.70%). Mentha x piperita increased menthol (16.31 to 41.26%), neomenthol (3.02 to 6.39%) and menthone (5.56 to 41.58%) contents during spring and summer, respectively. Whereas, M. viridis EO content did not show a quality response pattern in relation to seasonality. Therefore, harvest time for M. x piperita is recommended during spring, and for M. viridis is recommended during spring and summer.
