Neutrophil to Lymphocyte Ratio (NLR) in Peripheral Blood: A Novel and Simple Prognostic Predictor of Non-small Cell Lung Cancer (NSCLC)

OCLC Number/Unique Identifier: 7355938332
Lung cancer is the leading cause of cancer-related deaths worldwide, and almost accounts for 20% of these deaths, however, the cure rate is less than 10% [1]. Non-small cell lung cancer (NSCLC) accounts for approximately 85% of all cases of lung cancer [1], but fewer than 15% of individuals diagnosed with NSCLC can survive for more than 5 years, which poses a great threat to the patient’s life and health [2]. Recently, the incidence of lung cancer keeps dynamically growing, but more than 75% of patients at diagnosis has appeared local development or metastasis, missing the best period of surgery. Moreover, despite surgical treatment is the optimal choice for early-stage NSCLC patients, 30%-40% of patients with NSCLC develop tumor recurrence in a short time. Therefore, improving the prognosis of patients with lung cancer and predicting the long-term survival of patients is of particular importance [3]. At present, tumor and node metastasis (TNM) staging system, clinicopathological characteristics, visceral pleural invasion and marginal status are used to predict the disease progression and overall survival of NSCLC patients. There is no index which is stable, effective, reliable and less harmful to assess prognosis, predict recurrence risk and overall survival.
Primary Cutaneous Lymphomas and Interferon Treatment

Primary cutaneous lymphomas (PCLs) are the second most common group of extranodal non-Hodgkin lymphomas (NHL) with an estimated annual incidence of 1/100.000. Interferons (IFNs) are used in mono or combination therapy for cutaneous lymphomas especially for cutaneous T-cell lymphomas (CTCL) for years. IFN-α is the most widely-used type for cutaneous lymphomas. IFN-α has been shown to be a highly active agent in CTCL with response rates ranging from 40% to 80%. In this review, the current information about PCLs and IFNs treatment is summarized.

Polyolefin nanocomposites based on metallocene catalysts
Published on: 4th February, 2021
OCLC Number/Unique Identifier: 8941316701
In recent years polyolefin nanocomposites are of great interest because of their high potential as materials with novel properties [1,2]. The properties of the nanocomposites are not only influenced by the kind of fillers but also by the microstructure of the polyolefin, the distribution of the fillers, and the preparation process. Nanocomposites prepared by extrusion moulding of mixed polyolefin and nanoparticles show often less stability by agglomeration of the nanoparticles. A better distribution is obtained if the polymerization catalyst is absorbed on the surface of the nanoparticles. After adding an olefin a growing film of the polyolefin is covering every nanoparticle (in situ polymerization).
Corrosive base neutralization process: Review
Published on: 2nd December, 2020
OCLC Number/Unique Identifier: 9272363212
A balance response is the point at which a corrosive and a base respond to shape water and a salt and includes the mix of H+ particles and OH-particles to produce water. The balance of a solid corrosive and solid base has a pH equivalent to 7.
Recent approach to incorporate tellurium in metal carbonyl cluster utilizing extrusion reaction
Published on: 26th November, 2019
OCLC Number/Unique Identifier: 9269425535
The incorporation of tellurium into metal carbonyl using tellurium transfer/ extrusion reaction is presented in this work. The results bring one of the new ways to incorporate tellurium by transferring it from one molecule to another molecule, in comparison to the work so far where either insertion or extrusion reactions were shown. The reactions of PhC2TeC2Ph with the metal carbonyl cluster produced thermodynamically stable metal carbonyl tellurium clusters.
Micropollutants in wastewater irrigation systems: Impacts and perspectives
Published on: 9th July, 2019
OCLC Number/Unique Identifier: 8199206316
Climate change and the increasing global population pose a severe threat to the availability of freshwater in the world. Over consumption of water and deteriorating water quality are problems that should be addressed in order to ensure water availability for the coming decades. In this context, the increasing presence of micropollutants in water has shown to cause detrimental impact on water quality, given the negative disturbances that they can cause on human health and on the environment. Thus, it is important to study and quantify the presence of micropollutants in water bodies and also in regenerated wastewater based irrigation systems.
Biodegradation of waste streams containing benzene, toluene, ethylbenzene and xylene (BTEX): Practical implications and brief perspectives
Published on: 12th June, 2019
OCLC Number/Unique Identifier: 8165303442
Benzene (B), toluene (T), ethylbenzene (E) and xylene (X), collectively named as BTEX are mono-aromatic ring compounds with a 6-carbon benzene ring. Due to the presence of the aromatic ring, these compounds, especially benzene, are generally considered to be non-reactive species [1].
The pattern of blood pressure and renal function among children with Sickle Cell Anaemia presenting in a tertiary health institution in Nigeria
Published on: 16th April, 2019
OCLC Number/Unique Identifier: 8163611724
Background: In sickle cell anemia (SCA), compromise of the renal vasculature due to sickled red cells has been recognized.
Objectives: To assess the renal function and blood pressure pattern in children with sickle cell anaemia (SCA) presenting in a tertiary institution.
Method: A cross-sectional study of patients with sickle cell anaemia (SCA) over six months involving the use of questionnaires, general physical examination, blood pressure, investigations for haemoglobin genotype, urinalysis, serum creatinine, screening for hepatitis B and HIV.
Results: 51 children with SCA were seen. The prevalence of impaired renal function as defined by reduced eGFR <90mL/min/1.73m2 in this study was 27.5%, previous hospital admission and blood transfusion were associated with reduction in eGFR but blood pressure did not have significant correlation with the eGFR. The overall mean age at diagnosis of SCA was 4.09 ± 3.33 (years).
Conclusion: Impaired renal function is a major comorbid condition in children with SCA. In countries/locations where there is no newborn screening for sickle cell disease, diagnosis is delayed, thus detecting impaired renal function may be delayed, therefore the need for early detection and management is imperative.Introduction
Can bloodstream infection be predicted by nasal culture in hemodialysis patients?
Published on: 15th April, 2019
OCLC Number/Unique Identifier: 8163588486
The blood and drainage cultures are suggested for early diagnosis of bloodstream infection (BSI), which are time consuming and laborious. Nasal colonization of bacteria is one of the modalities, occasionally can predict BSI. We hypothesized that nasal culture, as an accessible fluid may be helpful to predict future BSI in hemodialysis patients. The present prospective study evaluated 63 patients undergoing maintenance hemodialysis at the Pars hospital dialysis center, Tehran, Iran, from November 2015 until February 2016. Nasal fluid of patients were collected from the 1–cm internal anterior part of both nostrils of patients by a sterile swab and cultured in Trypticase soy agar. All patients were followed for three months for BSI. The results of first nasal fluid sample revealed that 33.3% in first sampling and 27.0% in sampling had positive nasal fluid culture. The type of bacteria in all positive cases was Staphylococcus aureus. The rate of BSI infection in the patients with positive and negative first nasal fluid culture was 9.5% and 2.4% respectively with no significant difference. We found also no significant association between BSI positivity and nasal culture results so that positive BSI was revealed in 5.9% of patients with positive nasal fluid culture and 4.3% in those with negative nasal fluid culture with no meaningful difference. None of the baseline variables including age and gender, underlying risk factor, access, or duration of dialysis was associated with BSI positivity. In hemodialysis patients, BSI may not be predicted by nasal fluid culture positivity.
