LITERATUR REVIEW : KUALITAS HIDUP PASIEN LEUKEMIA

Leukemia is a malignant disease that attacks the hematopoiesis system, causing uncontrolled blood cell proliferation. Quality of life is one indicator that can be used to see the welfare conditions of patients suffering from chronic diseases such as leukemia. This review literature aims to find out the factors that influence the quality of life of leukemia patients. Literature search through Google Scholar, EBSCO, Springer Link, Elsevier, Sage databases using keywords: factors, quality of life, leukemia. The journals taken have a range from 2018 to 2020, which are then filtered according to the inclusion criteria set by the author. The results of the review indicate that there are several factors that affect the quality of life in leukemia patients, namely the therapeutic treatment undertaken, the patient's environment, and the role of care giver. Proper management of leukemia patients will improve the quality of life of these patients, and vice versa

The efects of alone and combined treatment of Tarantula cubensis alcoholic extract and Methenolone Enanthate on two long bones of young Rats

The aim of this study was to determine the effects of alone and combined treatment of Tarantula cubensis alcoholic extract (TCAE) and Methenolone Enanthate (ME) on morphometric parameters of humerus and femur in young rats. In this study, 36 five–week–old Wistar Albino rats were used. The animals were divided into 4 groups; Control group (n:6, normal saline solution, 0.2 mL·rat-1, subcutaneously –SC–), TCAE group (Tarantula cubensis alcoholic extract, 0.2 mL·rat-1, SC), ME group (Methenolone Enanthate), 10 mg·kg-1, intramuscularly –IM–) and TCAE + ME group (Tarantula cubensis alcoholic extract, 0.2 mL·rat-1, SC + Methenolone Enanthate, 10 mg·kg-1, IM). Drug treatments were done once a week for 7 weeks. At the end of the experiment, all the animals were euthanized and their humerus and femur bones were resected and their morphometric parameters were determined. No statistical differences were determined (P>0.05) between the groups in terms of the anatomical reference points (length, corpus thickness, cavum medullare diameter, and cortex thickness) of humerus and femur bones. In conclusion, it was found that alone and combined treatments of Tarantula cubensis alcoholic extract and ME (at normal dose) had no effects on morphometric parameters of humerus and femur bones in rats in the growing period. However, these effects may not be observed at high–dose and long–term treatments in rats

Modeling of the distribution of Purple-flowered Rhododendron (Rhododendron ponticum L.) under the current and future climate conditions

Bu çalışmanın amacı mor çiçekli orman gülü Rhodendron ponticum L. 'nin maximum entropi algoritması kullanılarak günümüz ve gelecek potansiyel yayılış alanlarının iklim senaryolarına göre modellenmesidir. İki aşamalı olarak yürütülen bu çalışmanın birinci aşamasında R. ponticum L.’nin çalışma alanı (Türkiye, Gürcistan ve Rusya sınırları) içerisindeki yayılışını temsil eden örnek noktalara ait (presence data) veriler ve biyoklimatik değişkenler kullanılmıştır. Yüksek korelasyonu ve çoklu doğrusallığı önlemek amacıyla, Worldclim 2.1 versiyonu 2.5 dakika (yaklaşık 20 km2 ) konumsal çözünürlükteki 19 biyoklimatik değişken Pearson Korelasyon analizi yapılarak 8 değişkene indirgenmiştir. İkinci aşamada ise türün yayılış alanlarının iklim değişiminden nasıl etkileneceğini belirlemek için CMIP6 modellerinden olan CNRM-CM6-1 iklim değişikliği modeli kullanılmış, SSP2 4.5 ve SSP5 8.5’e senaryolarına göre 2041-2060 ve 2081-2100 periyotlarına ait potansiyel yayılış alanı MaxEnt 3.4.1 programı kullanılarak modellenmiştir. Ayrıca, tür için tahmin edilen günümüz ve gelecekteki potansiyel yayılış alanları arasındaki alansal ve konumsal farklar, değişim analizi ile ortaya konulmuştur. Sonuçta, R. ponticum L.’nin potansiyel yayılış alanlarına göre üretilen bilginin teoriden pratiğe dönüşmesindeki temel faydalar sürdürülebilir peyzaj yönetimi kapsamında tartışılmıştır.This study aims to model the present and future potential distribution of Rhododendron ponticum L. species according to diverse climate scenarios using maximum entropy. Carried out in two stages, the present study utilized presence data representing natural distribution of R. ponticum L. species in Turkey, Georgia, and Russia. In the first stage, we determined variables of the climate models and focused on 19 bioclimatic variables (in 2.5 minute, or approximately 20 km2 , spatial resolution in Wordclim version 2.1) obtained for presence data from sample points. In order to prevent from high correlation and multi-collinearity, bioclimatic variables were reduced to 8 variables by performing Pearson correlation analysis. In the second stage, CNRM-CM6-1 climate change model, which is one of the CMIP6 models, was used to determine how the distribution areas of the species will be affected by climate change. Within this scope, the potential distribution areas of the species under the SSP2 4.5 and SSP5 8.5 scenarios in the periods 2041-2060 and 2081-2100 were modelled by means of the MaxEnt 3.4.1 software. Furthermore, spatial differences between the present and future potential distribution of the species were assessed by change analysis. In conclusion, this study suggested using produced knowledge and transforming them from theory to practice for underpinning sustainable landscape management

Construction of amperometric biosensor modified with conducting polymer/carbon dots for the analysis of catechol

Phenolic compounds used in food industries and pesticide industry, are environmentally toxic and pollute the rivers and ground water. For that reason, detection of phenolic compounds such as catechol by using simple, efficient and cost‐effective devices have been becoming increasingly popular. In this study, a suitable and a novel matrix was composed using a novel conjugated polymer, namely poly[1‐(5‐(4,8‐bis(5‐(2‐ethylhexyl)thiophen‐2‐yl)benzo[1,2‐b:4,5‐b']dithiophen‐2‐yl)furan‐2‐yl)‐5‐(2‐ethylhexyl)‐3‐(furan‐2‐yl)‐4H thieno[3,4‐c]pyrrole‐4,6(5H)‐dione] (PFTBDT) and carbon dots (CDs) to detect catechol. PFTBDT and CDs were synthesized and the optoelectronic properties of PFTBDT were investigated via electrochemical and spectroelectrochemical studies. Laccase enzyme was immobilized onto the constructed film matrix on the graphite electrode. The proposed biosensor was found to have a low detection limit (1.23 μM) and a high sensitivity (737.44 μA/mM.cm−2) with a linear range of 1.25–175 μM. Finally, the applicability of the proposed enzymatic biosensor was evaluated in a tap water sample and a satisfactory recovery (96–104%) was obtained for catechol determination.Publisher's Versio

Original Article Long-term effects of forgotten biliary stents: a case series and literature review

Abstract: There are many studies about the biliary stents, however there is a little information about the long-term stayed forgotten biliary stents except a few case reports. We have reported the results of a number of cases with biliary stents that were forgotten or omitted by the patient and the endoscopist. During February 2010 to May 2013, five patients were referred to the general surgery clinic of Haydarpasa Numune Training and Research Hospital, Istanbul Turkey. Past history and medical documents submitted by the patient did not indicate a replacement of the biliary stent in 3 patients. Two patients knew that they had biliary stents. We also conducted a literature review via the PubMed and Google Scholar databases of English language studies published until March 2014 on forgotten biliary stent. There were 3 men and 2 women ranging in age from 22 to 68 years (mean age 41.6 years). Patients presented with pain in the upper abdomen, jaundice, fever, abnormal liver function tests or dilatation of the biliary tract alone or in combination. Patients' demographic findings are presented i

A search for resonances decaying into a Higgs boson and a new particle X in the XH→qqbb final state with the ATLAS detector

A search for heavy resonances decaying into a Higgs boson ($H$) and a new particle ($X$) is reported, utilizing 36.1 fb$^{-1}$ of proton-proton collision data at $\sqrt{s} =$ 13 TeV collected during 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. The particle $X$ is assumed to decay to a pair of light quarks, and the fully hadronic final state $XH \rightarrow q\bar q'b\bar b$ is analysed. The search considers the regime of high $XH$ resonance masses, where the $X$ and $H$ bosons are both highly Lorentz-boosted and are each reconstructed using a single jet with large radius parameter. A two-dimensional phase space of $XH$ mass versus $X$ mass is scanned for evidence of a signal, over a range of $XH$ resonance mass values between 1 TeV and 4 TeV, and for $X$ particles with masses from 50 GeV to 1000 GeV. All search results are consistent with the expectations for the background due to Standard Model processes, and 95% CL upper limits are set, as a function of $XH$ and $X$ masses, on the production cross-section of the $XH\rightarrow q\bar q'b\bar b$ resonance

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
