Introduction

WOS: 000318196000020Comparative approaches between organic and conventional production systems allow the revealing of suitable crop management systems and perspectives for genetic improvement in grain crop production. For this purpose, two-year-field experiment with five advanced durum wheat lines was conducted under both organic and conventional conditions during 2008-2009 and 2009-2010 growing seasons. Grain yield and yield components (thousand grain weight, spike number per plant and grain number per spike) were determined. Significant positive correlation (r = 0.85**) was found between grain yield of wheat genotypes grown under organic and conventional conditions. Among yield components, a similar correlation (r = 0.74**) was evidenced only in grain number per spike. This suggests that the positive correlation between grain yield of wheat genotypes grown under both conditions is mainly regulated by this yield component. Our finding indicates that any conventional agronomic management which contributes to the increase of grain number per spike, or selected wheat cultivars which have higher value of this parameter may also be advantageous for organic wheat production systems. The critical phenological stage of expression of the character is pointed out, and the practical importance of the finding for facilitating the application of organic systems in durum wheat is underlined

WOS: 000324163700028In this study, estimation of narrow sense heritability, genetic correlations and relative effects of direct versus indirect selection were aimed for peduncle length, spike length, number of spikelet per spike and number of kernels per spike as selection was applied for shorter plant height in common wheat population of (Golia x Atilla-12) cross. While the indirect effect of direct selection for plant height was observed negative on number of kernels per spike, positive effect was obtained on peduncle length. It was understood that selection of peduncle length can be done indirectly through the selection for short plant height in the (Golia x Atilla-12), but while it had no effect on other components. Therefore, it was concluded that direct selection for short plant height can be done successfully, and on various selection practices and studies are necessary for the spike length, number of spikelet per spike and number of kernels per spike.

Splanchnic vein thrombosis following renal transplantation: a case report

BACKGROUND: Recurrent episodes of venous thrombosis have been closely correlated with JAK2 V617F mutation. Upto date, JAK2 gene mutation has not been defined as a prothrombic risk factor in renal transplant recipients. Herein; we present a case of portosplenic vein thrombosis in a primary renal transplant recipient with JAK2 V617F mutation who had no history of prior venous thromboembolism or thrombophilia. CASE PRESENTATION: A 59 year old female caucasian patient with primary kidney transplant admitted with vague abdominal pain at left upper quadrant. Abdominal doppler ultrasound and magnetic resonance imaging angiography demonstrated splanchnic vein thrombosis (SVT). The final diagnosis was SVT due to MPD (essential thrombocytosis, ET) with JAK2 V617F mutation. After 3 months of treatment with warfarin (≥5 mg/day, to keep target INR values of 1.9-2.5), control MRI angiography and doppler USG demonstrated partial (>%50) resolution of thrombosis with recanalization of hepatopedal venous flow. The patient is still on the same treatment protocol without any complication. CONCLUSION: JAK2 V617F mutation analysis should be a routine procedure in the diagnosis and treatment of kidney transplant patients with thrombosis in uncommon sites

Clinical Study Laparoscopic Treatment of Adrenal Tumors: A Single-Center Experience with 58 Patients

Background. The aim of this study is to discuss the laparoscopic approach and assess the immunohistochemical expression profiles of synaptophysin, Ki-67, and inhibin and patient outcomes in adrenal masses through a series of cases treated at our institution. Method. The study was conducted on 58 patients who were diagnosed with adrenal masses. All cases were operated on laparoscopically for adrenal masses. Results. Both inhibin and synaptophysin were found positive in 45 patients (77,6%). Ki-67 was negative in 11 patients, whereas it was found positive in 42 with a rate of 1%. The size of the masses ranged from 1 up to 9 cm (mean 4,3 ± 1,5). Urine hormone excretion was measured within normal ranges in 47 out of 58 patients (81%). Most of the diagnosed patients were harboring Cortical Adenoma ( : 38; 65,5%). All of the masses were successfully resected without complication except 3 patients. Because of complications of bleeding, the operation was converted to open surgery for 2 patients. Conclusion. Morbidity, mortality, and healing were comparable, regardless of tumor size, yet involvement in both laparoscopic and adrenal surgery was required. Our results suggested that laparoscopic adrenalectomy should replace open surgery as the standard treatment for most adrenal masses

Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

AN INNOVATIVE APPROACH TO PRODUCE FORAGE CROPS: BARLEY FODDER IN VERTICAL FARMING SYSTEM

WOS: 000581115600102The rapid growth of the world's population, limited natural resources and environmental challenges caused by climate change have had brought up global food security to the agenda. Scientific researches and new practices considering sustainable food production and efficient use of natural resources are getting more attention during last decades all around the world. Furthermore, advanced technological applications that enable new agricultural production systems such as vertical farm have been starting to emerge to provide a solution on this issue. Vertical farming which is the method of growing crops in vertically stacked layers under controlled environment is one of the promising techniques to protect environmental resources, provide continuous and sustainable plant production. Applications of vertical farming have already experienced in many countries such as Japan, Singapore, England, USA, Netherlands and the vertical agricultural market is expected to increase by 25% by 2024 to reach 11.4 billion Euro. Plant groups that are widely grown with vertical farming system are mostly; carrot, radish, potato, tomato, pepper, pea, cabbage, spinach, lettuce and strawberries. Although, cereal grain production in the vertical systems is not economically profitable today, considering remarkable increase in demands on forage crops, barley fodder production seems to have great potential for vertical farming systems. the benefits of the system such as less water use (about 90%), no herbicides, pesticides and fertilizer application relative to conventional production would be more pronounced for barley fodder in vertical system comparison to other conventional forage crops production systems. in this review, potential of barley fodder production in vertical farming system was discussed

ADAPTATION OF COTTON (Gossypium hirsutum L.) TO LIMITED WATER CONDITIONS: REVERSIBLE CHANGE IN CANOPY TEMPERATURE

WOS: 000549175400008Improving cotton yield under limited water supply needs to deeper understanding of the plant's response and adapting strategies to improve their tolerance. Effects of limited water conditions on ten cotton genotypes (Gossypium hirsutum L.) were examined in a field experiment to evaluate their tolerance level and explore time depending changes in canopy temperature and leaf greenness as indirect determinations of leaf water-status and chlorophyll density. Plant height shortened (15%), dry matter accumulation inhibited (36%), ball number (35%) and eventually lint yield (35%) decreased of all cotton genotypes since irrigation amount decreased 32% under limited watering conditions (LWC). Significant genotypic variation in tolerance level and yielding capacity under LWC were found among genotypes. Leaf tissues accumulated higher proline (stress-related amino acid) to adapt lower water potential conditions while canopy temperature depression (CTD) reversibly decreased and SPAD values were increased. A strong correlation between relative changes in CTD and SPAD values and a significant variation in ability of the cotton genotypes to recover CTD under limited water conditions were found. Our results also suggested that the higher ability to recover CTD of cotton leaves was associated with lower total dry weight reduction and water stress susceptibility under limited water conditions.Ege University (Scientific Research Projects Unit)Ege University [2014/ZRF/026]The data presented in this paper is the part of Master Thesis of Ugur Cakalogullari. the authors thank to the Research Fund of Ege University (Scientific Research Projects Unit) for their financial support to this study (Project no: 2014/ZRF/026).

MITIGATE GRAIN YIELD LOSSES OF WHEAT UNDER TERMINAL DROUGHT STRESS BY DIFFERENT NITROGEN APPLICATIONS

WOS: 000413647600045Water and nitrogen are both most limiting factors for plant growth and productivity. Effects of different nitrogen applications on grain yield of wheat under terminal drought stress were investigated in the present study. A field experiment was conducted with a bread wheat cultivar Gonen in two experimental sites characterized by loamy-sand (Menemen) and clay-loam (Bornova) soils. Rainout shelters were used to exclude rain from drought imposed plots during grain filling stage. Gradually decrease in soil moisture content caused significant decrease in grain yield in both experimental sites. However, higher yield were recorded in loamy-sand soils (LSs) than clay-loam soils (CLs) in all treatments. Thousand grain yield and grain number per spike were also decreased due to drought conditions. Similar to grain yield, both parameters were also significantly lower in CLs than LSs. Split nitrogen treatment included flowering stage caused a significant decrease in grain yield because of lower biomass production during earlier development stages. Our findings suggested that higher biomass which could be obtained by high earlier nitrogen application may provide an advantage in wheat production for later drought conditions.Ege University (Scientific Research Project)Ege University [2009ZRF064]The data presented in this paper is the part of PhD.
