Prognostic Biomarkers and Therapeutic Targets Identification Among CXC Chemokines in the Colon Adenocarcinoma Microenvironment

Background: COAD is among the most prevalent malignancy, with a very high incidence rate. Crosstalk between cancer and interstitial cells significantly affects cancer development, modulated partly by chemokines production. When present in the tumor microenvironment, CXC chemokines have been shown to regulate tumor cell activity and influence immune cell transport, resulting in anti-tumor immune mechanisms and influencing the outcomes of the patient; nonetheless, the CXC chemokines expression levels in COAD, as well as their prognostic significance, have not yet been established.Methods: This study used UALCAN, GeneMANIA, STRING, TRRUST, cBioPortal, TIMER, and GEPIA,Results: The expression of CXC1/2/3/5/6/11/12/13/14/16/17 in COAD patients was shown to be significantly correlated with the pathological stage. A considerably improved prognosis was observed in patients with low transcriptional levels of CXCL9/10/11. Differentially expressed CXC chemokines exert roles that are predominantly correlated with the chemokine signaling pathway and interactions of cytokine–cytokine receptors. Our findings indicated that the transcriptional factors, including SP1, RELA, and NFKB1 are essential for the production of CXC chemokines. Furthermore, we discovered a substantial association between the CXC chemokines production and infiltration of 6 kinds of immune cells (CD8+ T cells, dendritic cells, B cells, CD4+ T cells, neutrophils, and macrophages,). Conclusions: These findings might be useful in identifying prognostic indicators and immunotherapeutic targets for colon cancer.

The study reports on the analysis of the anamnestic data of2044 women with reproductive disorders who underwent operative interventions for tumors and tumorlike masses of the ovaries during the period of 1989-1999 in the Research Center of Obstetrics, Gynecology and Perinatology of the Russian Academy of Medical Sciences. A high incidence rate о f complicated anamnesis and the coexisting somatic and extragenital diseases was revealed. The data are presented concerning the status of menstrual and reproductive function of the patients examined.

Analysis of the malignant ovarian tumors incidence in the Sumy region in 2014-2018.

Background. Ovarian cancer is a very important pathology of the female reproductive system and tends to increase in incidence and mortality rates around the world. Despite the fact that ovarian cancer prevalence is lower than that of breast and cervical cancer, its mortality rate is three times higher. Aim. To analyze the incidence of ovarian cancer in the female population of Ukraine and the Sumy region in 2014–2018. Methods. Data from the National Cancer Register of Ukraine were used for this work. A statistical analysis of the incidence rates of ovarian cancer in the population of Ukraine and Sumy region was carried out. Results. The highest incidence of ovarian cancer in the Sumy region was detected in 2018 (12.5 cases per 100,000 women), and the lowest - in 2017 (10.4 cases per 100,000 women). This pathology occurs most often in women 60-79 years old. 91% of the tumors were epithelial-stromal tumors, of which 75% were serous ovarian adenocarcinomas. Ovarian cancer in most cases was diagnosed at the third stage of the disease (47% of cases), which indicates a low level of early diagnosis of this tumor. Conclusion. In the Sumy region, a high incidence rate of ovarian cancer was revealed, which exceeds the national one and has a significant age dependence. Serous ovarian adenocarcinoma is the most common type of ovarian cancer. This pathology is diagnosed mainly at the 3rd stage.

NEW APPROACH FOR TREATMENT OF CUTANEOUS LEISHNIANIASIS BY MAN NITOL

The present study was carried outinHaWija District and surrounding villages. Three villages were chosen (Al-Kadhemia,Sader A1-Naher, A1-Ameniea). The high incidence rate of cutaneous leishmaniasis was during the Winter months (December 1996 to March 1997). The total positive cases were 227 ( 111 males and 116 females). The highest incidence rate was among childeren fiom 1-10 years old. Intralesional mannitol solution was shown to be more effective ( 93.89% ) than Hypertonic Sodium Chloride 7% (HSCS) ( 87.50% ) but almost identical to pentostam ( 96.20% ). Most of lesions were cured in first and second injection, in all three treated groups but few of them needed the third injection. In all three treated groups, the scar was absent or minimum afier healing. None of the control lesions cured-within 6-8 Weeks. It is concluded that 20% rnannitol is aneffective local method of treatment for acute cutaneous leishmaniasis. The efficacy of 20% of mannitol is identical to pentostam and greater than 7% “ HSCS”. i

How Identifying Circumgalactic Gas by Line-of-sight Velocity instead of the Location in 3D Space Affects O vi Measurements

The high incidence rate of the O vi λλ1032, 1038 absorption around low-redshift, ∼L * star-forming galaxies has generated interest in studies of the circumgalactic medium. We use the high-resolution EAGLE cosmological simulation to analyze the circumgalactic O vi gas around z ≈ 0.3 star-forming galaxies. Motivated by the limitation that observations do not reveal where the gas lies along the line of sight, we compare the O vi measurements produced by gas within fixed distances around galaxies and by gas selected using line-of-sight velocity cuts commonly adopted by observers. We show that gas selected by a velocity cut of ±300 km s−1 or ±500 km s−1 produces a higher O vi column density, a flatter column density profile, and a higher covering fraction compared to gas within 1, 2, or 3 times the virial radius (r vir) of galaxies. The discrepancy increases with impact parameter and worsens for lower-mass galaxies. For example, compared to the gas within 2 r vir, identifying the gas using velocity cuts of 200–500 km s−1 increases the O vi column density by 0.2 dex (0.1 dex) at 1 r vir to over 0.75 dex (0.7 dex) at ≈ 2 r vir for galaxies with stellar masses of 109–109.5 M ⊙ (1010–1010.5 M ⊙). We furthermore estimate that excluding O vi outside r vir decreases the circumgalactic oxygen mass measured by Tumlinson et al. (2011) by over 50%. Our results demonstrate that gas at large line-of-sight separations but selected by conventional velocity windows has significant effects on the O vi measurements and may not be observationally distinguishable from gas near the galaxies.

Vacinação Contra a COVID-19 numa Rede de Clínicas de Hemodiálise em Portugal: Uma Experiência Promissora

Introduction: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for coronavirus disease 2019 (COVID-19) seriously affected Portugal, particularly in the elderly population with a high number of comorbidities, including patients with chronic kidney disease in stage 5 (CKD-5D) undergoing a regular dialysis program. The aims of this study were to identify the impact of vaccination on the incidence of new daily cases and mortality in the CKD-5D population.Material and Methods: Prospective, observational study, involving patients with CKD-5D from 38 NephroCare clinics, Portugal. Daily SARS-CoV-2 infections and mortality among these patients was compared with the incidence in the general population. Three periods were analysed: before vaccination, during the vaccination process, and a third period after complete vaccination with the Pfizer-BioNTech’ Comirnaty® vaccine. The primary outcome was infection by the SARS-CoV-2 virus and the secondary outcome was death associated with the infection.Results: A total of 4617 patients (average of 69.37 years of age) were analysed. During the first period, there was a significantly higher COVID-19 incidence of 14.9% in patients with CKD-5D compared with the general population (7.9%; p < 0.001). During the fifteen days after the complete vaccination, results reverted to a significant decrease in COVID-19 cases was observed (p < 0.001). The mortality rate among CKD-5D was significantly higher than in the general population (p < 0.001).Discussion: A high incidence rate of infection was observed in CKD-5D patients, probably due to several factors such as advanced age, number of comorbidities, inability to remain in confinement, among others. After vaccination there was a significant reduction of new cases.Conclusion: Vaccination significantly reduced SARS-CoV-2 infection in patients with CKD-5D.

Assessment of the impact of the quality of drinking water on the primary morbidity of children in the Altai Territory

The number of environmental factors that adversely affect the health of children is growing every year, their combination is different in each territory. It is the child’s body that is most sensitive to changes in environmental conditions, reacting to this with a deterioration in health. Currently, there is a tendency to study the regional characteristics of the interaction of a set of environmental factors with the child’s body. The aim of the work was to identify trends in the primary non-infectious morbidity among children in the Altai Territory, as well as to assess the possible impact of the state of drinking water on the morbidity of children in the region. In the region, an unfavorable tendency was revealed in such groups of nosologies as neoplasms, diseases of the endocrine system, diseases of the circulatory system, diseases of the digestive system, diseases of the genitourinary system, congenital anomalies, and diseases of the respiratory system. The regularity of distribution over the territory of the region of administrative-territorial formations with a high incidence rate was revealed. The analysis of associations of morbidity in children with average annual concentrations of substances polluting the atmospheric air and drinking water showed the presence of reliable correlations in areas of critical and stressful environmental quality. The results obtained indicate the need for a detailed assessment of the influence of environmental factors on the incidence rate of children in the regional aspect, the formation of a database and the development of automated programs capable of predicting the incidence rate in each specific territory. This will improve the efficiency, including the economic, of preventive measures.

Epidemiologic and clinical characteristics of human bocavirus infection in infants and young children suffering with community acquired pneumonia in Ningxia, China

Background Pneumonia has a high incidence rate and is a major cause of mortality in children, mostly community-acquired pneumonia (CAP). Human bocavirus (HBoV), since it first identified in 2005, has been repeatedly associated with respiratory tract infections. Nevertheless, the role and related information of HBoV as a pathogen of CAP has not been fulfilled. Here our study is to assess the epidemiological and clinical features in HBoV-positive children with CAP. Methods A total of 878 secretions of lower respiratory samples were obtained, multiplex PCR was used to detect HBoV and other respiratory viruses. Results Of all cases, HBoV was detected in 10.0%, with a peak incidence of infection among children < 2 year old, and predominantly noted in autumn and winter. Only 8 patients were HBoV single infection. Co-infection with other respiratory viruses was observed in 86.4%. Moreover, co-infection with bacteria occurred in 27.3% and with Mycoplasma pneumoniae (MP) in 33.0% of HBoV-positive patients. Among all HBoV-positive samples co-infected with bacteria, 87.5% are gram negative bacteria. Compared with HBoV-negative group, age (P = 0.048), wheezing (P = 0.015), tachypnea (P = 0.016), lactate dehydrogenase (P = 0.026) and severe pneumonia (P = 0.023) were statistically significant in HBoV-positive patients. Furthermore, HBoV-positive patients less than 1 year old were more likely to have co-infection with bacteria (P = 0.007). Conclusions HBoV can be detected alone in respiratory samples of children with CAP, maybe it is one of the causes of CAP in infants. The high incidence of severe pneumonia was found in HBoV-positive patients compared with HBoV-negative cases may indicate a relationship between severe pneumonia and HBoV.

COVID-19 patients age, comorbidity profiles and clinical presentation related to the SARS-CoV-2 UK-variant spread in the Southeast of France

The variant 20I/501Y.V1, associated to a higher risk of transmissibility, emerged in Nice city (Southeast of France, French Riviera) during January 2021. The pandemic has resumed late December 2020 in this area. A high incidence rate together with a fast turn-over of the main circulating variants, provided us the opportunity to analyze modifications in clinical profile and outcome traits. We performed an observational study in the University hospital of Nice from December 2020 to February 2021. We analyzed data of sequencing of SARS-CoV-2 from the sewage collector and PCR screening from all positive samples at the hospital. Then, we described the characteristics of all COVID-19 patients admitted in the emergency department (ED) (n = 1247) and those hospitalized in the infectious diseases ward or ICU (n = 232). The UK-variant was absent in this area in December, then increasingly spread in January representing 59% of the PCR screening performed mid-February. The rate of patients over 65 years admitted to the ED decreased from 63 to 50% (p = 0.001). The mean age of hospitalized patients in the infectious diseases ward decreased from 70.7 to 59.2 (p < 0.001) while the proportion of patients without comorbidity increased from 16 to 42% (p = 0.007). Spread of the UK-variant in the Southeast of France affects younger and healthier patients.
