Quality assessment of surgery for colorectal cancer: Where do we stand?
Authors: Morarasu Stefan , Livadaru Cristian , Dimofte Gabriel-Mihail
Published: April 2024

Quality assurance in surgery has been one of the most important topics of debate among colorectal surgeons in the past decade. It has produced new surgical standards that led in part to the impressive oncological outcomes we see in many units today. Total mesorectal excision, complete mesocolic excision (CME), and the Japanese D3 lymphadenectomy are now benchmark techniques embraced by many surgeons and widely recommended by surgical societies. However, there are still ongoing discrepancies in outcomes largely based on surgeon performance. This is one of the main reasons why many countries have shifted colorectal cancer surgery only to high volume centers. Defining markers of surgical quality is thus a perquisite to ensure that standards and oncological outcomes are met at an institutional level. With the evolution of CME surgery, various quality markers have been described, mostly based on measurements on the surgical specimen and lymph node yield, while others have proposed radiological markers (i.e. arterial stumps) measured on postoperative scans as part of the routine cancer follow-up. There is no ideal marker; however, taken together and assembled into a new score or set of criteria may become a future point of reference for reporting outcomes of colorectal cancer surgery in research studies and defining subspecialization requirements both at an individual and hospital level.
Carcinoembryonic antigen in the diagnosis, treatment, and follow-up of focal liver lesions
Authors: Dilek Osman Nuri , Arslan Kahraman Dilara İrem , Kahraman Gökhan
Published: April 2024

In this editorial review, we comment on the article published in the recent issue of the World Journal of Gastrointestinal Surgery . Carcinoembryonic antigen (CEA) is a fetal glycoprotein and can be secreted in very small amounts from healthy adults after birth. CEA is widely used not only for diagnostic tumor markers but also importantly for the management of some gastrointestinal tumors. The most common clinical use is surveillance for the monitoring of colorectal carcinoma. However, CEA can become elevated in several malign or benign characterized pathologies. Serum CEA level may vary depending on the location of the lesion, whether it metastasizes or not, and its histopathological characteristics. It has been determined that cases with high preoperative CEA have a more aggressive course and the risk of metastasis to the lymph tissue and liver increases. In this editorial review, we focused on evaluating the role of CEA in clinical practice with a holistic approach, including the diagnostic and prognostic significance of CEA in patients with focal liver lesions, the role of CEA in follow-up after definitive surgery, and also hepatic resection for metastasis, and the management of all patients with raised CEA.

This study explores the extent of leachate contamination and groundwater vulnerability in urban dumpsites, with a specific focus on the Ipata area in Ilorin, Nigeria. The study employs a combination of 2D Electrical Resistivity Tomography (ERT), soil classification, and physicochemical analyses to investigate the percolation of leachate into groundwater and its potential environmental and health implications. The ERT data unveiled subsurface layers, highlighting the presence of decomposed topsoil down to approximately 1.2m. Beneath this layer, a low-resistivity zone (6.53 to 10.7 ?m) indicated the potential risk of leachate percolation into groundwater. Soil classification revealed a shallow topsoil layer with insufficient clay content to hinder leachate penetration, emphasizing the need for enhanced containment measures. Physicochemical analysis of leachate, well water, and soil displayed variations in key parameters such as pH, electrical conductivity, total dissolved solids, and anion concentrations. Leachate exhibited high pH and electrical conductivity, suggesting elevated total dissolved solids, while well water remained within acceptable pH limits for drinking water. Heavy metal concentrations exceeded permissible WHO limits in topsoil, leachate, and well water, with cadmium presenting a high ecological risk. The absence of persistent organic pollutants (POPs) in the samples indicates a current focus on heavy metals as a primary concern. In conclusion, this study underscores the urgent need for proactive pollution abatement measures in urban dumpsites like Ipata. Regular monitoring of surface and groundwater quality is essential to safeguard public health and the environment.

Authors: Ponsadai Lakshmi S. , Gopi C. , Adwin Jose P.
Published: April 2024

This paper aims to evaluate the quality of groundwater resources used for irrigation purposes using a Mamdani-type fuzzy inference system (MFIS). The MFIS is used to resolve ambiguities and uncertainties in economic, social, and natural systems and also facilitates the capture of expert knowledge in ways similar to human reasoning and thought processes. In this study, 20 groundwater samples were collected from various locations within the Mayiladuthurai district, Tamil Nadu, India, between January 2016 and December 2019. These samples underwent physical and chemical analyses to assess the suitability of the collected water resources for irrigation. The analysis utilizes the Mamdani Fuzzy Inference System, which combines values of Electrical Conductivity (EC) and Sodium Adsorption Ratio (SAR). Additionally, methods from the US Salinity Laboratory Staff were also employed. Ultimately, the groundwater quality in Mayiladuthurai is graded for irrigation use by this method. The results indicate that the MFIS reduces imprecision and uncertainty in data handling through the fuzzy membership function. The comparison of irrigation suitability results clearly demonstrates that the proposed MFIS method offers an improved assessment of the irrigation water quality level of the studied groundwater resources.

Published: April 2024

The effect of the magnetic field on the onset of thermal convection in a porous layer saturated by Jeffrey nanofluid is studied. Three distinct boundary conditions are considered to be free-free, rigid-rigid and rigid-free boundaries. The model used for Jeffrey nanofluid includes the effect of Brownian motion and thermophoresis. The normal mode analysis as well as the Galerkin first approximation technique is used. The effects of the Rayleigh number of nanoparticles, Lewis number, modified diffusivity ratio, Jeffery parameter, porosity and Chandrasekhar number are investigated analytically and graphically. It is discovered that the Chandrasekhar number, Lewis number and modified diffusivity ratio have a stabilizing effect while the Jeffery parameter, nanoparticles Rayleigh number and porosity have a destabilizing effect. This study induces the effect of Chandrasekhar number and Jeffrey nanofluid. We have analyzed that Chandrasekhar number produces a stabilizing effect on the onset of convection i.e. it delays the onset of convection whereas the Jeffrey parameter which comes from Jeffrey nanofluid shows the destabilizing effect on the onset of convection i.e. it accelerates the onset of convection. The influence of a magnetic field on the commencement of nanofluid convection is significant in magnetohydrodynamic power generators, electrical equipment, petroleum reservoirs, nuclear reactors, biochemical engineering, chemical engineering and geophysics.

n this study, the influence of maceration time on the chemical and sensory properties of the red wine grape variety Prokupac (Vitis viniferae L.) was investigated. The main focus was on the total phenolic content (TPC) and other chemical components of the wine whose content is influenced by maceration time and other conditions of vinification. The addition of yeast could also influence the properties of the wine, which is why spontaneous and inoculated fermentation were observed. In both cases, maceration lasted 0, 3, 5, 7, 14 and 21 days, respectively. The highest extracted value of TPC was reached on the 12th day during inoculated fermentation (1940.11 mg GAE/L) and on the 21st day during spontaneous fermentation (1793.00 mg GAE/L). Apart from TPC and other chemical components of the wine, these values depend on the wine technology used.

Authors:   University of Kragujevac, Faculty of Agronomy, Serbia, Nikolić Milan P.
Published: April 2024

Raw spirits were produced through distillation of apple wines obtained by fermentation of selected varieties of apples. Two types of apple wine were obtained using different apple varieties. In the first case, the wine was obtained from two types of apples: Red Elstar and Vilmuta. In the second case, the wine was obtained from mixture composed of four types of apples: Idared, Golden Delicious, Jonagold and Melrose. The aromatic profiles of obtained raw spirits were strongly influenced of desirable aromas of ethylesters which contribute to the flavour of the destillates with a pleasant fruity and flowery smell, indicative of the quality of the spirit. A headspace solid phase microextraction (HS-SPME) as the extraction technique and gas chromatography coupled with mass spectrometry was utilized for the determination of volatile compounds. It was shown that raw spirits obtained from mixed combination of Red Elstar and Vilmuta have more intense aroma than obtained from second mixture (Idared, Golden Delicious, Jonagold and Melrose). Ethyl nonanoate, ethyl 9-hexadecanoate, ethyl palmitate and 9,12-octadecanoic acid ethyl ester were detected only in raw spirits obtained from Red Elstar and Vilmuta. The aroma profile of the fractions obtained during the distillation was also investigated. The most intensive aroma was detected in the first fractions (heads). On the other side, the content of ethyl esters in middle fractions was lower than that in the first fractions.

Published: April 2024

Acute coronary syndromes (ACS) are critical medical emergencies that can disrupt the progression of coronary artery disease at any given time. Cardiac troponin I levels are precise and sensitive markers for detecting acute myocardial infarction (AMI). Assessing the incidence of Major Adverse Cardiovascular Events (MACE) in patients experiencing AMI is pivotal for guiding medical interventions. This study investigates the association between cardiac troponin I levels and the frequency of MACE in individuals diagnosed with AMI. Employing an observational analytic approach with a cross-sectional design, the research focuses on patients diagnosed with AMI, including both ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), admitted to Gotong Royong Hospital in Surabaya from January to December 2023. The relationship between troponin I level and MACE was examined through bivariate analysis using the Chi-square test within SPSS 23.0 software. Among the 76 participants, the majority were aged over 65 years (39.5%), with 51 males (67.1%), and 59 patients were diagnosed with NSTEMI (77.6%). MACE occurred in 39 individuals (51.4%) with AMI, notably including heart failure in 69.2% of cases. Regarding cardiac troponin I (cTnI) values, 17 patients had STEMI, while 59 were diagnosed with NSTEMI. Within the AMI group, 6.6% were classified in Group 1, 26.3% in Group 2, and 67.1% in Group 3. Remarkably, a significantly higher proportion of patients with MACE exhibited markedly elevated cTnI levels in Group 3 (78.3%). In summary, the study highlights a significant association between cardiac troponin I levels and the occurrence of major adverse cardiovascular events (MACE) in patients with acute myocardial infarction at Gotong Royong Hospital in Surabaya.

Authors: Bashir Marriam , Ullah Nazeef , Rana Samina
Published: April 2024

This research paper is an attempt to stylistically analyze the technique of foregrounding through the graphological structures in the selected poems of Haris Khalique. The researcher has used qualitative method and the graphological features including variation in the length of lines, abundant use of comma and other punctuation marks in the two selected poems are qualitatively and descriptively analyzed in the light of foregrounding theory. The findings of the research, in line with the objectives, are that the smart use of graphical features and graphological structures play an important role in bypassing the general norms of grammar and syntax and customary expectations of writings to foreground ideas. The first poem of analysis deals through reminisce with the past trauma of the partition and the subsequent pathetic situation of law and order. While the second poem of analysis deals with the sufferings of common people and their wretchedness due to the menace of terrorism and the apathetic approach of the state machinery towards improving human security. The working emotions, feelings and key concepts in both poems are heavily foregrounded with the help of the graphological structure through the means of sentence length, word order and punctuations.

Published: April 2024

The present study aims at analyzing the narrative structure of the famous short story “The Gift of the Magi” by implementing Greimas’s (1966) Actantial Model. “The Gift of the Magi” is written by O. Henry. It is quite enigmatic to find out the real subject of the story as both Della and Jim seem to be the subject and object at the same time. The Actantial model of Greimas is a wonderful framework to solve this puzzle. Therefore, the study tries to identify the real ‘subject’ of the story, analyzing the text of the story by applying Greimas’ model of Actantial. Not only this, but the study also identifies the other actants’ roles such as the object, the helper, the opponent, the sender, and the receiver in the story, their contribution to the narrative structure, the character and non-character actants and their role in the development of the plot. The textual analysis of the narrative, by the implementation of Greimas’ model, shows that Della is the real ‘subject’ of the story, Jim the object and the receiver both, the non-character actant ‘Christmas’ as the sender, Della’s passion of love and sacrifice as the helpers and her poverty as the opponent.

This study's primary goal is to identify war trauma in the Hanif book that was chosen. Red Birds (2018), his masterwork, was chosen by the researcher for research. By using Freud's Psychoanalysis Theory (1901) and Caruth's Trauma Theory (1996) the researcher has examined this book. The researcher discovered that the novel's protagonists have mental illnesses brought on by the conflict. Several different things can induce mental disturbances. These elements include overkill bombing, a lack of essential services in conflict areas, homelessness, the murder and kidnapping of family members, and excessive bombardment. Also, the study discovered that the war victims are dealing with inferiority complexes and that this mental disease prompted self-shattering. Children and adults respond to combat trauma in different ways. When compared to the adult characters in the novels, children are far more influenced. The trauma of war has profound and enduring repercussions on children. The individuals in the book are afflicted with a variety of psychiatric disorders as a result of this battle trauma. This study demonstrates how extensively the impacts of war trauma on the lives of the characters are shown in Hanif's work.
