Land-use dynamics associated with mangrove deforestation for aquaculture and the subsequent abandonment of ponds

Highlights SAR data is useful for tracking dynamic changes in mangrove ecosystem. Time series SAR data can be used to estimate lifespan of pond. During 22+ years, over half of the mangrove forest in Mahakam Delta has been converted to aquaculture. Abstract The objective of this study was to evaluate the spatiotemporal dynamics of large area mangrove deforestation, aquaculture pond building, and the subsequent abandonment of ponds in a large delta in Indonesia, namely the Mahakam Delta. So, we developed and applied a novel methodology for exploring the lifespan of aquaculture ponds. Using historical multispectral and radar data, the lifespans of aquaculture ponds across the delta were estimated via a chronological analysis of the landscape into four different states: primary mangroves → deforested mangroves → ponds → abandoned/inactive ponds. Specifically, a combination of sequential classification and rule-based techniques were used to: 1) produce a time series of land cover maps from 1994 to 2015 and 2) quantify lifespans of aquaculture ponds in the delta. Results show that of the 110,000 ha of primary mangrove forests in the delta in 1994, 62% had been deforested by 2015, with a 4.5% annual rate of loss on average. The lifespan of aquaculture ponds in the delta varied between 1 and 22+ years, with most of the ponds having productive lifespans of 10 to 13 years. Ponds with relatively longer lifespans were located near the existing settlements in the delta. This study showed that the productive lifespan of most aquaculture ponds in deforested mangrove lands of Mahakam delta is relatively short, information that should be useful for developing appropriate management plans for the delta or similar coastal mangrove ecosystems. The abandoned ponds can potentially be rehabilitated for shrimp and fish production after applying appropriate restorative treatments or be targeted for mangrove restoration projects

Health-related Quality of Life of Cancer Caregivers in Klang Valley, Malaysia

Cancer caregiving has an impact on the quality of life (QOL) of the caregivers. This cross-sectional study determined the health-related QOL (HRQOL) of gastrointestinal cancer caregivers and associated factors across gender. A total of 323 respondents from major hospitals in Klang Valley completed HRQOL questionnaire from October 2017 to April 2018. Males had a better quality of life compared to females, mean HRQOL score 85.52 (SD=21.16) vs 77.66 (SD=21.36). The significant factors were: relationship between the caregiver and the patient; education level; employment status, marital status, household income and presence of disease. The gender role is vital for targeted intervention. Keywords: health-related quality of life; gastrointestinal cancer; caregivers; gender eISSN: 2398-4287© 2020. The Authors.

Evaluation of the anesthetic effects of xylazine-ketamine, xylazine-tiletamine-zolazepam and tiletamine-zolazepam using clinical and laboratory parameters in rabbits

The aim of this study was to evaluate the anesthetic effects of xylazine-ketamine (XK), xylazine-tiletamine-zolazepam (XTZ) and tiletamine-zolazepam (TZ) using hematological and biochemical parameters in rabbits. A total of 18 rabbits were divided into three equal treatment groups (n = 6). The rabbits in the XK, XTZ, and TZ groups were administered xylazine (5 mg/kg) and ketamine (50 mg/kg), xylazine (5 mg/kg) and TZ (15 mg/kg), and TZ (15 mg/kg), respectively, via the intramuscular route. Following the injection, their reflexes were tested every 5 minutes. Heart rate, respiratory rate, and body temperature were determined before the injection (0 min) and at 5, 15, 30, 45, 60, 75, 90, and 120 min after injecting the anesthetic combinations. Furthermore, hematological and biochemical (alanine transaminase [ALT], aspartate transaminase [AST], alkaline phosphatase [ALP], bilirubin, blood urea nitrogen [BUN], and urea) analyses were also performed before, during, and after anesthesia administration. The duration of anesthesia and loss of reflexes were significantly longer in the XTZ group than in the other groups. However, in the TZ group, reflexes were remained. Respiratory rate and body temperature decreased in all the groups. Moreover, heart rate reduced only in the XK and XTZ groups, and the hematological parameters of all groups were comparable. Serum AST and ALP levels increased in the XTZ group compared to that in the XK and TZ groups, respectively. However, these increases were within the reference limits. The post-anesthesia serum BUN and urea levels significantly increased in the XTZ group (p < 0.05) compared to that in the other groups. Thus, although the XTZ combination provided satisfactory anesthetic effect in rabbits, it may be nephrotoxic. Therefore, its use for anesthesia induction in invasive renal procedures and experimental nephrotoxicity studies is not advisable

Optimization and analysis of surface roughness, flank wear and 5 different sensorial data via Tool Condition Monitoring System in turning of AISI 5140

Optimization of tool life is required to tune the machining parameters and achieve the desired surface roughness of the machined components in a wide range of engineering applications. There are many machining input variables which can influence surface roughness and tool life during any machining process, such as cutting speed, feed rate and depth of cut. These parameters can be optimized to reduce surface roughness and increase tool life. The present study investigates the optimization of five different sensorial criteria, additional to tool wear (VB) and surface roughness (Ra), via the Tool Condition Monitoring System (TCMS) for the first time in the open literature. Based on the Taguchi L9 orthogonal design principle, the basic machining parameters cutting speed (vc), feed rate (f) and depth of cut (ap) were adopted for the turning of AISI 5140 steel. For this purpose, an optimization approach was used implementing five different sensors, namely dynamometer, vibration, AE (Acoustic Emission), temperature and motor current sensors, to a lathe. In this context, VB, Ra and sensorial data were evaluated to observe the effects of machining parameters. After that, an RSM (Response Surface Methodology)-based optimization approach was applied to the measured variables. Cutting force (97.8%) represented the most reliable sensor data, followed by the AE (95.7%), temperature (92.9%), vibration (81.3%) and current (74.6%) sensors, respectively. RSM provided the optimum cutting conditions (at vc = 150 m/min, f = 0.09 mm/rev, ap = 1 mm) to obtain the best results for VB, Ra and the sensorial data, with a high success rate (82.5%)

Different epidemiology of bloodstream infections in COVID-19 compared to non-COVID-19 critically ill patients: a descriptive analysis of the Eurobact II study

Bloodstream infection; COVID-19; EnterococcusInfección del torrente sanguíneo; COVID-19; EnterococoInfecció del torrent sanguini; COVID-19; EnterococBackground The study aimed to describe the epidemiology and outcomes of hospital-acquired bloodstream infections (HABSIs) between COVID-19 and non-COVID-19 critically ill patients. Methods We used data from the Eurobact II study, a prospective observational multicontinental cohort study on HABSI treated in ICU. For the current analysis, we selected centers that included both COVID-19 and non-COVID-19 critically ill patients. We performed descriptive statistics between COVID-19 and non-COVID-19 in terms of patients’ characteristics, source of infection and microorganism distribution. We studied the association between COVID-19 status and mortality using multivariable fragility Cox models. Results A total of 53 centers from 19 countries over the 5 continents were eligible. Overall, 829 patients (median age 65 years [IQR 55; 74]; male, n = 538 [64.9%]) were treated for a HABSI. Included patients comprised 252 (30.4%) COVID-19 and 577 (69.6%) non-COVID-19 patients. The time interval between hospital admission and HABSI was similar between both groups. Respiratory sources (40.1 vs. 26.0%, p < 0.0001) and primary HABSI (25.4% vs. 17.2%, p = 0.006) were more frequent in COVID-19 patients. COVID-19 patients had more often enterococcal (20.5% vs. 9%) and Acinetobacter spp. (18.8% vs. 13.6%) HABSIs. Bacteremic COVID-19 patients had an increased mortality hazard ratio (HR) versus non-COVID-19 patients (HR 1.91, 95% CI 1.49–2.45). Conclusions We showed that the epidemiology of HABSI differed between COVID-19 and non-COVID-19 patients. Enterococcal HABSI predominated in COVID-19 patients. COVID-19 patients with HABSI had elevated risk of mortality. Trial registration ClinicalTrials.org number NCT03937245.

Association between aortic stiffness and left ventricular function in inflammatory bowel disease

Background: Recent studies have reported an increased incidence of both aortic stiffness and left ventricular (LV) systolic and diastolic dysfunction in patients with inflammatory bowel disease (IBD). However, the association between aortic stiffness and the LV function has not been fully defined. We aimed to investigate the relationship between aortic stiffness and the LV function in IBD patients. Methods and Results: Seventy-two patients with IBD (56 cases of ulcerative colitis and 16 cases of Crohn’s disease) and 50 healthy controls were consecutively enrolled in this study. The LV systolic and diastolic functions were assessed using conventional echocardiographic techniques, including tissue Doppler echocardiography. The degree of aortic strain and distensibility were calculated based on the aortic diameters measured on M-mode echocardiography at the level of 3 cm above the aortic valve and the blood pressure values obtained on sphygmomanometry. There were significant differences between the IBD and control group in the degree of aortic strain and distensibility. Significant differences were also observed between the patient and control groups in the parameters of the LV systolic and diastolic functions. Moreover, aortic stiffness was found to be associated with the LV function in the patient group. Conclusions: There is a significant relationship between aortic stiffness and LV systolic and diastolic dysfunction in patients with IBD, based on the findings of this study. The parameters of aortic elasticity measured according to 2-dimensional echocardiographic methods can be beneficial for predicting early cardiovascular risk in cases of IBD. (
