Synthesis of 2-aminothiazole sulfonamides as potent biological agents: Synthesis, structural investigations and docking studies. Heliyon 2024; 10:e34980. [PMID: 39157352 PMCID: PMC11327602 DOI: 10.1016/j.heliyon.2024.e34980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 07/18/2024] [Accepted: 07/19/2024] [Indexed: 08/20/2024] Open
Abstract
A simplified synthetic approach involving sulfonylation followed by amino group alkylation produced new 2-aminothiazole derivatives. UV/Vis, infrared, and NMR spectroscopies confirmed their structures. Compounds 36, 22, 34, and 35 showed strong inhibition against Jack bean and Bacillus Pasteurii urease, with IC50 values from 14.06 to 20.21 μM/mL. Compounds 20, 26, 21, 29, 30, 31, and 32 exhibited potent inhibitory effects against α-glucosidase and α-amylase, with IC50 values between 20.34 and 37.20 μM/mL. Compounds 33, 26, and 27 demonstrated potent DPPH scavenging, with IC50 values around 34.4-39.2 μM/mL. FMO analysis showed compounds 21, 22, 24, and 25 having parallel aromatic ring systems due to π cloud interactions, while compounds 32 and 38 had distinct electronic density distributions. Compound 22 had HOMO and LUMO energy gaps of 5.805 eV, with bromo and fluoro substitutions in compounds 21 and 24 slightly increasing the gaps to 6.089 eV and 6.078 eV, respectively. Nitro groups in compounds 25 and 32 reduced the gaps to 0.384 eV and 1.187 eV. All compounds demonstrated high gastrointestinal absorption, non-permeability to the blood-brain barrier, and optimal skin permeation (Log Kp between -5.83 and -6.54 cm/s). Compounds 22, 24, and 38 had promising QED scores of 0.719, 0.707, and 0.860, respectively, with synthetic accessibility scores from 2.057 to 2.517. ADMET predictions indicated minimal toxicity, cardiovascular safety, and significant inhibitory potential for CYP enzymes. Strong in silico binding affinities (binding energies -5.75 to -7.63 kcal/mol) and metabolic stability suggest these derivatives are promising candidates for further drug development.

Studies on the ameliorative potential of Rheum webbianum rhizome extracts on 1,2-dimethylhydrazine (DMH) induced colorectal cancer and associated hepatic and haematological abnormalities in swiss albino rats. JOURNAL OF ETHNOPHARMACOLOGY 2024; 335:118652. [PMID: 39097213 DOI: 10.1016/j.jep.2024.118652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 07/15/2024] [Accepted: 07/30/2024] [Indexed: 08/05/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rheum webbianum Royle (RW) holds significant ethnopharmacological importance owing to its 5000-year history of cultivation for medicinal and culinary purposes. Demonstrating therapeutic advantages in traditional and contemporary medical practices, RW exhibits key pharmacological effects including anticancer activity, gastrointestinal control, anti-inflammatory properties, and suppression of fibrosis. Despite its recognized vast bioactivities in ethnopharmacology, its efficacy against the colorectal cancer (CRC) remains incompletely understood. AIM OF THE STUDY This study for the first time aims to investigate the chemo-preventive capabilities of various extracts derived from RW rhizomes against CRC development. MATERIALS AND METHODS Four types of RW extracts were prepared by using different solvents viz: Hexane, Ethy-acetate, Ethanol and Methanol. All the four extracts were evaluated for cytotoxicity on HCT-116 human CRC cells. Promising extracts were further investigated in-vivo at varying doses using 1,2-dimethylhydrazine (DMH) induced rat CRC model to assess the anti-oxidant and anticancer properties as well as their effects on the associated hepatic deterioration and hematological alterations. RESULTS Cell viability: In-vitro assessments demonstrated a dose and time-dependent reduction in HCT-116 cell viability following treatment with methanolic and ethanolic extracts of RW, reducing viability by up to 85% and 90%, respectively, at 200 μg/ml. HISTOPATHOLOGY Histopathological analyses revealed significant improvements in colon tissue morphology in RW extract-treated groups compared to DMH-only treated animals. RW-treated groups showed reduced structural abnormalities, congestion, inflammatory cell infiltration, crypt abscess formation, and dysplasia. In contrast, the DMH-only group exhibited irregular glandular structure, mucosal destruction, extensive inflammatory cell infiltration, crypt abscess formation, and dysplasia. These results highlight the potential of RW methanolic and ethanolic extracts in mitigating colon cancer-related histopathological alterations. Haematological, and hepatic parameters: In the DMH-induced colorectal cancer rat model, significant hematological imbalances were evident, including a 49.13% decrease in erythrocytes, 32.18% in hemoglobin, and 26.79% in hematocrit, along with a 79.62% increase in white blood cells and 68.96% rise in platelets. Administration of RW rhizome extracts effectively restored these hematological parameters to levels comparable to those in the control group. Furthermore, RW treatment significantly reduced serum ALT and AST levels, which had increased by 36.78% and 33.12%, respectively, due to DMH exposure. RW intervention also mitigated the onset of atherosclerosis, evidenced by notable reductions in serum total cholesterol and triglyceride levels. Comparative analysis indicated that RW-treated DMH groups effectively restored lipid profiles, contrasting with the DMH-only group which exhibited markers indicative of colon cancer. Oxidative stress: The DMH-treated group showed a significant increase in MDA levels by 195.59%, indicative of heightened free radical production, coupled with decreased levels of SOD (33%), CAT (48%), GSH (58%), and GR activity (49%), signifying oxidative stress. Treatment with RW extracts in DMH-treated rats markedly reduced MDA levels and enhanced SOD, CAT, GSH, and GR activities. These results underscore the antioxidant efficacy of RW extracts. CONCLUSION This study underscores the significant potential of RW rhizome extracts in inhibiting colorectal cancer development. Further investigations are warranted to identify the active constituents responsible for these promising outcomes, positioning RW as a natural and potential agent in combating colon cancer.

Abstract
Objective To determine the association between MetS and its components with cervical cancer among women in South-western Uganda. Methods We conducted an unmatched case-control study on 470 participants in a 1:2 case-to-control ratio among women in southwestern Uganda. We recruited 157 women with cervical cancer as cases and 313 women without cervical cancer as controls at the Mbarara Regional Referral Hospital Cervical Cancer Clinic. We assessed for MetS using the National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III) criteria. We used a multivariable binary logistic regression analysis to determine the association between MetS and its components with cervical cancer adjusted for potential confounders. We reported the adjusted odds ratios (aOR) and 95% confidence intervals (CI). Results Cases were significantly older than controls: 52.4 ± 13.15 versus 41.9 ± 11.9 respectively, p < 0.001. We found MetS was independently associated with cervical cancer (aOR 1.66; 95 % CI 1.07-2.57). Age ≥ 50 years (aOR-2.20; 95 % CI 1.35-3.56), HIV infection (aOR 2.51, 95 % CI 1.56-4.05), increasing parity (aOR 1.16, 95 % CI 1.06-1.26), and a lack of formal education (aOR 6.41, 95 % CI, 1.33-30.86) were also associated with cervical cancer. However, none of the components of MetS was associated with cervical cancer. Conclusion In Ugandan women, MetS was associated with a higher likelihood of cervical cancer. We, therefore recommend combined screening for MetS and cervical cancer in order to reduce morbidity and mortality from both Mets and cervical cancer.

Abstract
Chronic kidney disease (CKD) has been correlated with certain pathological conditions such as cardiovascular diseases and other renal-related dysfunctions. Some other reports suggested an association between CKD and the development of certain solid cancers. Therefore, we aimed to generate this narrative review to present the available literature on the risk of solid cancer development in CKD patient populations. We explored the associations between CKD, organ transplantation, and the development of specific solid organ tumors such as kidney, thyroid, lung, breast, bladder, gastric, and prostate cancers. In conclusion, the previous reports showed an increase in the risk of certain solid cancers such as kidney, lung, bladder, and possibly breast cancer in CKD patients and transplant recipients. On the other hand, thyroid, gastric, and prostate cancers showed unclear association with CKD. Despite the suggested impact of smoking and immunosuppression on the development of cancers in CKD patients, more studies are needed to elucidate the mechanism and the risk factors that might be related to the development of cancer in CKD patients.

Abstract
Chitosan (CTS), has emerged as a highly intriguing biopolymer with widespread applications, drawing significant attention in various fields ranging from medicinal to chemosensing. Key characteristics of chitosan include solubility, biocompatibility, biodegradability and reactivity, making it versatile in numerous sectors. Several derivatives have been documented for their diverse therapeutic properties, such as antibacterial, antifungal, anti-diabetic, anti-inflammatory, anticancer and antioxidant activities. Furthermore, these compounds serve as highly sensitive and selective chemosensor for the detection of various analytes such as heavy metal ions, anions and various other species in agricultural, environmental and biological matrixes. CTS derivatives interacting with these species and give analytical signals. In this review, we embark on an exploration of the latest advancements in CTS-based materials, emphasizing their noteworthy contributions to medicinal chemistry spanning the years from 2021 to 2023. The intrinsic biological and physiological properties of CTS make it an ideal platform for designing materials that interact seamlessly with biological systems. The review also explores the utilization of chitosan-based materials for the development of colorimetric and fluorimetric chemosensors capable of detecting metal ions, anions and various other species, contributing to advancements in environmental monitoring, healthcare diagnostics, and industrial processes.

Abstract
PURPOSE To determine the correlation between HPV (human papillomavirus) 52 viral load, multiple infections and ThinPrep cytology test (TCT), to inform clinical management of HPV52-positive women after cervical cancer screening. METHODS A total of 1,882 female patients who had positive quantitative HPV tests at Yuebei People's Hospital from January 2020 to December 2022, of whom 533 tested positive for HPV52. We excluded patients who combined HPV16 and/or HPV 18 positivity and whom HPV52 viral load could not be calculated. The final enrollment was 488 patients, including 400 NILM, 48 ASC-US, 28 LSIL and 12 HSIL. The HPV test is a quantitative multiplexed fluorescent PCR assay that provides both HPV genotyping and viral load. RESULTS In our study, there were differences in the median distribution of viral loads among various cytological class categories. The risk of TCT results (LSIL or worse) was increased with the increase of HPV52 viral load, for every LOG unit increase in HPV52 viral load, the risk increased by 26.6%. More importantly, we found a nonlinear relationship between HPV52 viral load and TCT results (LSIL or worse) in both single and multiple infections. When the viral load reaches a threshold, the risk of abnormal cytological results increases significantly. CONCLUSION HPV52 viral load is an independent risk factor for TCT results (LSIL or worse). The relationship between HPV52 viral load and TCT results (LSIL or worse) is not linear. Viral load may be used as a triage indicator for HPV52-positive patients, thus improving the post-screening clinical management of HPV52-positive women.

Abstract
Background: Colorectal cancer (CRC) is the second most widespread cancer among Palestinian patients. As cancer care improves in hospitals across the West Bank, services like palliative care, targeted therapy, bone marrow transplantation, and individualized therapy are still limited. This study aimed to assess the CRC stages, treatment protocols, and survival rates of patients in the West Bank. Methodology: This retrospective study collected data from the medical records of Al-Najah University Hospital (NUH), which specializes in the care of cancer patients. Patients with confirmed CRC (stages I-IV) undergoing surgical or medical treatment were included in the study. Data collection was standardized by using a data collection form to gather information from the medical records included in the study. All statistical analyses were performed using SPSS (version v27), and survival was assessed using a regression analysis of the number of days from the time of diagnosis to the most recent visit against the type of treatment (e.g., surgery, chemotherapy, radiotherapy). Results: A sample of 252 patients with CRC from NUH was collected, including 143 males and 109 females aged between 27 and 86 years, with the average age being 60.6 ± 11.4 years. The sample included 183 patients (72.6%) diagnosed with colon cancer only, 29 patients (11.5%) diagnosed with rectal cancer only, and 40 patients (15.9%) diagnosed with both. Diagnosis took place at CRC stage I for 3 patients (1.2%), stage II for 33 patients (13.1%), stage III for 57 patients (22.6%), and stage IV for 159 patients (63.1%). Surgery was the most prevailing mode of treatment for 230 patients (91.3%), while 227 patients (90.1%) received chemotherapy treatment, and 38 patients (15.1%) received radiotherapy. Of the 252 patients, 40 patients (15.8%) received FOLFOX (i.e., folinic acid, fluorouracil, oxaliplatin), and 25 patients (9.9%) received FOLFIRI (i.e., folinic acid, fluorouracil, irinotecan), while the 187 remaining patients (74.2%) were treated with capecitabine, oxaliplatin, bevacizumab, cetuximab, regorafenib, cisplatin, etoposide, gemcitabine, or a combination thereof. The sample was categorized into six outcomes: (1) death, (2) cure, (3) disease progression, (4) disease recurrence, (5) under-treatment, and (6) unknown. Mortality was high, with 104 patients (41.3%) dying within a short time after diagnosis, and may have been attributable to delayed diagnosis. Surgical treatment had a positive impact on increasing the survival years, and it was significant (p = 0.033). Conclusions: A high percentage of patients were diagnosed in advanced CRC stages. The treatment modes were adopted from general international guidelines; however, the cure rates were low, and mortality was high. More studies need to be undertaken to investigate the actual application of chemotherapy protocols, and survival would benefit from the involvement of clinical pharmacists in the chemotherapy protocol selection, dosing, frequency, and follow-up. The present study advocates for greater public awareness of CRC and attests to the merits of screening by primary care professionals, which can help to avoid this serious illness and to promote a better prognosis.

Abstract
Helicobacter pylori infection is widespread in 50% of the world's population and is associated with gastric ulcers and related disorders that ultimately culminate in gastric cancer. Levofloxacin-based, or clarithromycin-based, triple therapy is frequently used to inhibit the bacterial urease enzyme for the eradication of H. pylori. A comprehensive investigation based on the urease inhibitory profiles of antibiotics and their computational implications is lacking in the scientific literature. The present study was aimed specifically to determine the antiurease activities within the realms of cephalosporins and fluoroquinolones by in vitro methods supported with in silico investigations. The results demonstrate the jack bean urease inhibitory activity of cephalosporins, wherein cefadroxil, cefpodoxime, cefotaxime, and cefaclor displayed inhibitions (IC50 21.35 ± 0.64 to 62.86 ± 0.78 μM) compared with the standard thiourea (IC50 21.25 ± 0.15 μM). Among fluoroquinolones, levofloxacin, ofloxacin, and gemifloxacin (IC50 7.24 ± 0.29 to 16.53 ± 0.85 μM) unveiled remarkable inhibitory profiles. Levofloxacin and ofloxacin exhibited competitive inhibition against the said enzyme. Ciprofloxacin and moxifloxacin displayed weak urease inhibitions. During molecular docking studies, Asp362, Gly279, Arg338, Asn168, Asp223, Gln364, and Met366 were involved in hydrogen bonding in fluoroquinolones, and hydrogen bonding was established with Arg338, His248, Asn168 residues, and metal Ni601 and Ni602 of the enzyme. MD simulations and MMPBSA results demonstrated the existence of significant protein-ligand binding. Overall, these results warrant further investigations into the significance of these active molecules in relation to their inhibitory potential against the targeted urease enzyme.

Abstract
Immunoassays are commonly used in disease diagnosis and vaccine evaluation but can be costly and time-consuming when confronted with multivalent targets, such as antisera containing antibodies to human papillomavirus (HPV), because of their limited ability to discriminate between multiple analytes in a single reaction well. This study describes the development of a high-throughput liquid chip system that combines immunoassay techniques and magnetic beads to allow the simultaneous screening and quantitative detection of antibodies to four types of HPV using the Luminex fluoroimmunoassay system. Groups of beads embedded with fluorescent dyes at various ratios were coated with optimized HPV capture antigens and demonstrated excellent dose-dependent response to four monoclonal antibodies used as reference standards. This assay is sensitive, accurate, repeatable, and simple to perform, enabling multiplex antibody detection with a high degree of orthogonality. The performance of the Luminex system was compared with conventional immunoassays for quantitative detection of quadrivalent HPV antibodies in antisera of mice immunized with five lots of HPV vaccines, verifying the accuracy and detection efficiency of the assay. This strategy is a promising approach to characterizing antibodies present in polyclonal antisera and has promising applications in research, clinical, and industrial settings, for example, streamlining vaccine efficacy trials and vaccine lot inspection and release procedures.

Abstract
Background Systemic therapy in lung cancer is mainstay of treatment as most patients present in advanced stages, with rising importance of new immunotherapy agents. Purpose To compare the RECIST 1.1 and the immunotherapy Response Evaluation Criteria in Solid Tumors (iRECISTs) criteria for response assessment in lung cancer patients on immunotherapy. To find the incidence of pseudoprogression and associated imaging patterns. Material and Methods Retrospective study in 28 patients treated with immunotherapy for advanced metastatic NSCLC. End points were progression-free survival (PFS) and overall survival (OS). Response assessments were separately tabulated according to RECIST 1.1 and iRECIST and classified into dichotomous groups of responders and nonresponders. Agreement in assessments between RECIST 1.0 and iRECIST examined using Cohen kappa (κ) coefficient with 95% confidence intervals. Kaplan-Meier survival analysis was done for PFS and OS. Differences between RECIST 1.1 and iRECIST for both responder and nonresponder were evaluated by the log rank test, Breslow (Generalized Wilcoxon) test, and Tarone-Ware test. Results Incidence of pseudoprogression was 7% (2/28). The RECIST1.1 and iRECIST were in disagreement in two patients. The agreement between RECIST and iRECIST was almost perfect. The PFS and the OS are significantly longer in duration for responders in comparison to nonresponders for both RECIST and iRECIST and the difference between two assessment criteria is not significant. Conclusion Although iRECIST aims to monitor treatment more precisely than conventional response criteria, this must be weighed against how infrequent pseudoprogression is and the cost of this therapy, both financially and in the potential delay in changing to a more effective treatment.

Abstract
Cases of digestive cancers diagnosed during pregnancy are rare. The increasing prevalence of pregnancy in women aged 30-39 years (and not exceptionally 40-49 years) could explain the frequent co-occurrence of cancers and pregnancy. The diagnosis of digestive cancers in pregnancy is difficult due to the overlap between neoplasm symptomatology and the clinical picture of pregnancy. A paraclinical evaluation may also be difficult depending on the trimester of the pregnancy. Diagnosis is also delayed by practitioners' hesitation to use invasive investigations (imaging, endoscopy, etc.) due to fetal safety concerns. Therefore, digestive cancers are often diagnosed during pregnancy in advanced stages, where complications such as occlusions, perforations, and cachexia have already arisen. In this review, we highlight the epidemiology, clinical aspects, paraclinical evaluation, and particularities of the diagnosis and treatment of gastric cancer during pregnancy.

Abstract
BACKGROUND Proximal gastrectomy (PG) has been excluded from the arsenal of western surgical oncologists for fear of bile reflux and diet intolerance. However, it is often an appropriate, less morbid operation for patients requiring resection of a proximal gastric cancer. METHODS Between 2013 and 2017, we performed 19 PG and 37 total gastrectomies (TGs), of whom 15 and 25 were alive at the time of data collection. In this single-center series, we present findings of a 10-question interview of patients who underwent proximal (n = 8) or TG (n = 16) regarding postgastrectomy food-related symptoms, based on a modified version of the validated Postgastrectomy Syndrome Assessment Scale. RESULTS Out of 7 Likert scale questions, there were no statistically significant differences between the groups regarding bile reflux, early satiety, appetite, energy level, physical activity limitations, pain, or general dissatisfaction with their surgery. Patients from both groups reported eating similar amounts of their preoperative volume per meal and overall food volume for the day. Both groups reported eating a similar number of snacks and meals throughout the day. Food satisfaction scores, calculated by summation of the Likert scores, were not different. CONCLUSION Although limited by the small population, we did not find a clinically relevant difference in food-related symptoms comparing PG and TG patients. This pilot study suggests that PG is an appropriate alternative to TG in certain populations. Anecdotal beliefs regarding potential bile reflux or diet intolerance should be reconsidered.

Abstract
The altered expression of ARMCX1 in patients with gastric cancer has been reported frequently, yet its correlation to prognosis and chemotherapy needs to be unveiled. In combination of the gene expression data retrieved from TCGA database and bioinformatic analysis, this study discovered 590 differentially expressed genes in the cancerous biopsies isolated from gastric patients, compared with controls. Among which, ARMCX1 exhibited great potential to serve as a prognostic biomarker for gastric patients; furthermore, patients with low expression of ARMCX1 could be more sensitive to these 9 chemotherapeutic agents: A-770041, AMG-706, ATRA, BEZ235, bortezomib, CGP60474, dasatinib, HG-64-1, and pazopanib, rather than the other chemotherapeutic agents. This study helps the improvement of evaluating the prognosis of gastric cancer patients, and would help optimize chemotherapeutic strategies in consideration of the expression of ARMCX1.

Abstract
BACKGROUND Aberrant expression of Secretory Leukocyte Protease Inhibitor (SLPI) has been associated with human cancer growth and its suppression was identified as a potential target for anti-cancer drugs, particularly in colorectal cancer. However, the underlying mechanism by which SLPI affected the development of drug resistance in CRC remains unclear. OBJECTIVE This study investigated the role of SLPI in the p53-up-regulated modulator of apoptosis (PUMA)-mediated CRC cells' apoptosis and their chemosensitivity to Cisplatin. METHODS A series of qRT-PCR and western blot analyses were performed to characterize the expressions of SLPI, PUMA, and Akt in CRC lines. Tunel, transwell, and CCK-8 analyses were monitored to define the impacts of the siRNA-mediated knockdown of SLPI on CRC cell development. Furthermore, in vivo development of CRC was evaluated in nude mice infected with siSLPI or Cisplatin alone or both, and Ki67 and caspase-3 immunohistochemistry assay was monitored on multiple tissue microarray from the same cohort. RESULTS Our results showed that SLPI inhibition strongly promoted the expressions of the pro-apoptotic protein PUMA, cleaved-caspase3 and Bax and reduced the cell viability of HT29 and HT116 cell lines in vitro. In addition, siSLPI knockdown effectively suppressed both Akt and FoxO3 proteins and improved the sensitivity to cisplatin chemotherapy. Xenograft tumor assay revealed a lowered growth in mice treated with Cisplatin, while combined treatment of siSLPI achieved more significant anticancer effects than Cisplatin alone. CONCLUSIONS Taken together, these findings demonstrated that suppression of SLPI might repress the growth of human colorectal cancer cells both in vitro and in vivo. These results suggested SLPI as a novel resistance factor to Cisplatin, and a combination of Cisplatin and SLPI inhibitor be beneficial for colorectal cancer therapy.

Abstract
PURPOSE The study aims to explore the regulatory mechanism of miR-129-2-3p underlying esophageal carcinoma (EC) cell progression and generate new ideas for targeted treatment of EC. METHODS Mature miRNA expression data and total RNA sequencing data of EC in the TCGAESCA dataset were utilized to explore differentially expressed miRNAs (DEmiRNAs). StarBase database was then utilized to predict targets of miRNA. MiR-129-2-3p and DNMT3B expression in EC cell lines was assayed through qRT-PCR and Western blot. CCK-8, scratch healing, and transwell assays were conducted to assess the impact of miR-129-2-3p on EC cell phenotypes. In addition, a dual-luciferase assay was completed to identify the binding relationship between DNMT3B and miR-129-2-3p. RESULTS MiR-129-2-3p was noticeably less expressed in EC cell lines, while DNMT3B was highly expressed. MiR-129-2-3p could bind to DNMT3B. Furthermore, in vitro functional experiments uncovered that overexpressed miR-129-2-3p repressed EC cell progression while further overexpressing DNMT3B would restore the above inhibitory effect. CONCLUSION MiR-129-2-3p is a cancer repressor in EC cells, and it could target DNMT3B, thus hampering the progression of EC cells.

Abstract
Breast cancer is the most common neoplasm in the world among women. The age-specific incidences and onset ages vary widely between Asian and Western countries/regions. Invasive breast cancer cases among women from 1997 to 2011 were abstracted from the International Agency for Research on Cancer and the Taiwan Cancer Registry. Age-period-cohort analysis was performed to examine the trends. The cohort effect was prominent in South Korea, Taiwan, Japan, and Thailand, possibly related to the timing of westernization. The risk of breast cancer initially rose with the birth cohorts in Hong Kong and India (both former British colonies), peaked, and then declined in recent birth cohorts. Unlike other Asian countries/regions, virtually no birth cohort effect was identified in the Philippines (a Spanish colony in 1565 and the first Asian country to adopt Western cultural aspects). Moreover, an at-most negligible birth cohort effect was identified for all ethnic groups (including Asian immigrants) in the United States. This global study identified birth cohort effects in most Asian countries/regions but virtually no impact in Western countries/regions. The timing of westernization was associated with the birth cohort effect.

Abstract
Several infections can predispose to certain malignancies in different body parts. These infections include viral, bacterial, and fungal pathogens. Imaging plays a vital role in the diagnosis, staging, and management of these neoplastic conditions. Furthermore, it can help in differentiating infection-related non-neoplastic processes that can mimic malignancies. Both radiologists and clinicians should be familiar with these conditions. This review discusses the epidemiology, pathogenesis, and imaging features of infection-related tumors.

Abstract
Circular RNAs (circRNAs) are a type of endogenous non-coding RNA and a critical epigenetic regulation way that have a closed-loop structure and are highly stable, conserved, and tissue-specific, and they play an important role in the development of many diseases, including tumors, neurological diseases, and cardiovascular diseases. CircSMARCA5 is a circRNA formed by its parental gene SMARCA5 via back splicing which is dysregulated in expression in a variety of tumors and is involved in tumor development with dual functions as an oncogene or tumor suppressor. It not only serves as a competing endogenous RNA (ceRNA) by binding to various miRNAs, but it also interacts with RNA binding protein (RBP), regulating downstream gene expression; it also aids in DNA damage repair by regulating the transcription and expression of its parental gene. This review systematically summarized the expression and characteristics, dual biological functions, and molecular regulatory mechanisms of circSMARCA5 involved in carcinogenesis and tumor progression as well as the potential applications in early diagnosis and gene targeting therapy in tumors.

Abstract
Endometrial cancer is a common malignancy in women worldwide, with myometrial invasion (MI) being an important prognostic factor, usually assessed via imaging techniques. The aim of this review is to compare the diagnostic accuracy of 3D transvaginal ultrasound (3D-TVUS), a relatively new imaging modality, to that of 2D transvaginal ultrasound (2D-TVUS) and MRI in the prediction of deep myometrial invasion. Relevant articles were sought on MEDLINE/PubMed, Scopus, Web of Science and Wiley Online Library databases. Articles were included if they were primary studies comparing 3D-TVUS to 2D-TVUS and/or MRI in adult endometrial cancer patients, with histopathological confirmation of MI as a reference standard. Ultimately, 7 studies were included, with 714 participants, 242 with deep MI and a mean age of approximately 60 years. 3D-TVUS, 2D-TVUS, MRI and 3D-TVUS-MRI co-evaluation had a pooled sensitivity of 80.4%, 77.6%, 80.7% and 94.6% respectively and a specificity range of 82.8%, 81.6%, 87% and 69.1% respectively. Overall, no statistically significant differences were found in sensitivity and specificity among 3D-TVUS and the other methods, except for a significant increase in sensitivity (p = 0.038) when combined with MRI. This shows that 3D-TVUS is comparable to MRI as far as diagnostic accuracy is concerned, however remains cheaper, less time-consuming and more tolerable, while offering some advantages over 2D-TVUS as well. Therefore 3D-TVUS application in MI assessment seems promising, although more research is required to further assess this finding and ascertain 3D-TVUS's place in endometrial cancer MI assessment.

Abstract
Some malignancies have very few technologies available for screening, and advancements in cancer therapy have not been as effective in lowering death as those for other chronic diseases. The major method for decreasing cancer incidence is primary avoidance through dietary and environmental changes. The potentially reversible risk factors were projected to be responsible for cancer-related mortality worldwide. Of these fatalities, many of the cases occurred in high-income nations, whereas very few cases did so in low- and middle-income countries. Risk factors in Europe and Central Asia were responsible for the majority of cancer mortality in low- and middle-income regions. Smoking, drinking alcohol, and eating few fruits and vegetables were some of the primary factors that contributed to cancer mortality both globally and in low- and middle-income countries. In high-income countries, alcohol consumption, smoking, and obesity were the main cancer-causing factors. The sexual transmission of the human papillomavirus is one of the leading risk factors for cervical cancer in women in low- and middle-income countries.

Oral Health in Breast Cancer Women with Vitamin D Deficiency: A Machine Learning Study. J Clin Med 2022; 11:jcm11164662. [PMID: 36012901 PMCID: PMC9410090 DOI: 10.3390/jcm11164662] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 07/24/2022] [Accepted: 08/08/2022] [Indexed: 12/14/2022] Open
Abstract
Breast cancer (BC) survivors treated with aromatase inhibitors (AIs) commonly show several pathological issues, including poor oral health, bone health impairment, and vitamin D deficiency. However, to date, oral health issues in BC survivors treated with AIs have been poorly investigated and their relationship with vitamin D deficiency are far from being understood. This study aimed to evaluate the correlation between oral health and vitamin D status in BC survivors undergoing treatment with AIs through a machine learning approach. In this cross-sectional study, we included post-menopausal BC women with vitamin D deficiency undergoing AIs therapy. The outcome measures were the following: oral health indexes as the Decayed, Missing, and Filled Permanent Teeth Index (DMFT); serum levels of 25(OH)D3; Bone Mineral Density (BMD); and the diagnosis of osteoporosis. We included 41 post-menopausal BC women, mean aged 66.10 ± 8.47 years, with mean serum levels of vitamin D of 14.63 ± 6.62 ng/mL. Furthermore, 56.10% of patients had a diagnosis of osteoporosis and 36.59% were osteopenic. DMFT was significantly related to smoking (p-value = 0.005) and dental floss use (p-value = 0.001). There was a significant correlation between DMFT and vitamin D levels (Pearson’s r: −0.73; p-value = 0.001). The regression machine learning model showed that vitamin D status and the use of dental floss were the most relevant variables in terms of correlation with DMFT. In conclusion, vitamin D deficiency, inadequate use of dental floss, and smoking had a negative impact on oral health in BC women. Thus, vitamin D deficiency screening and supplementation and a prompt oral rehabilitation plan should be suggested and implemented in the complex treatment framework of BC survivors undergoing treatment with AIs.

Cancer Epidemiol Biomarkers Prev 2022; 31:1572-1581. [PMID: 35654420 PMCID: PMC9344906 DOI: 10.1158/1055-9965.epi-21-1323] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 03/24/2022] [Accepted: 05/23/2022] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND The aim was to investigate time trends for incidence and long-term net survival in the morphologic subtypes and stages of cervical cancer in Sweden during the period 1960 to 2014. METHODS Women with invasive cervical cancer were identified through the Swedish Cancer Registry. Incidence and net survival were calculated according to morphology, age at diagnosis, and FIGO stage at diagnosis. RESULTS In total, 29,579 cases of invasive cervical cancer between 1960 and 2014 were included. The age-standardized incidence for squamous cell carcinoma (SCC) decreased until 2000; thereafter, the incidence rate stagnated, and a small increase was found in 2014. The incidence of adenocarcinoma continuously increased. The age-standardized 5-year net survival increased. However, decreasing net survival with increasing age was found. A higher stage at diagnosis showed a worse net survival. SCC and adenocarcinoma did not statistically differ as regards net survival in the last years of the study. CONCLUSIONS Age-standardized 5-year net survival improved between 1960 and 2014. A positive trend for short- and long-term net survival was seen for women ages 18 to 64 years but long-term net survival for women ≥75 years decreased. In this study, age and FIGO stage at diagnosis were found to be important prognostic factors in determining net survival. The morphologies, SCC, and adenocarcinoma did not statistically differ as regards net survival in the last years of the study. IMPACT This study demonstrates longitudinal data on cervical cancer in Sweden for over 50 years with sub analyses on morphology, age, and stage at diagnosis.

Abstract
Piperazine-based dithiocarbamates serve as important scaffolds for numerous pharmacologically active drugs. The current study investigates the design and synthesis of a series of dithiocarbamates with a piperazine unit as well as their biological activities. Under ultrasound conditions, the corresponding piperazine-1-carbodithioates 5a–5j were synthesized from monosubstituted piperazine 2 and N-phenylacetamides 4a–4j in the presence of sodium acetate and carbon disulfide in methanol. The structures of the newly synthesized piperazines were confirmed, and their anti-lung carcinoma effects were evaluated. A cytotoxic assay was performed to assess the hemolytic and thrombolytic potential of the synthesized piperazines 5a–5j. The types of substituents on the aryl ring were found to affect the anticancer activity of piperazines 5a–5j. Piperazines containing 2-chlorophenyl (5b; cell viability = 25.11 ± 2.49) and 2,4-dimethylphenyl (5i; cell viability = 25.31 ± 3.62) moieties demonstrated the most potent antiproliferative activity. On the other hand, piperazines containing 3,4-dichlorophenyl (5d; 0.1%) and 3,4-dimethylphenyl (5j; 0.1%) rings demonstrated the least cytotoxicity. The piperazine with the 2,5-dimethoxyphenyl moiety (5h; 60.2%) showed the best thrombolytic effect. To determine the mode of binding, in silico modeling of the most potent piperazine (i.e., 5b) was performed, and the results were in accordance with those of antiproliferation. It exhibits a similar binding affinity to PQ10 and an efficient conformational alignment with the lipophilic site of PDE10A conserved for PQ10A.

Abstract
AbstractPreoperative chemotherapy and preoperative chemoradiation, both improve survival for locally advanced esophageal cancer proven in randomized trials and metanalysis. Limited data are available comparing these preoperative therapies especially in non-gastroesophageal junction squamous cell cancer of esophagus. In this retrospective analysis, 69 eligible patients of locally advanced esophageal cancer, who underwent preoperative chemoradiation followed by surgery or chemotherapy followed by surgery at our center were analyzed. The end points of study were overall survival, disease free survival, and histopathological response. Three weekly paclitaxel and carboplatin was used as neoadjuvant chemotherapy and weekly paclitaxel and carboplatin were used with radiation as per standard protocol. Median follow-up time was 35 months for surviving patients. Median overall survival was 44 months (95% CI 27.2–62.7) in chemoradiation group and it was not reached in the chemotherapy arm (p-value −0.832). The median disease-free survival for patients who underwent preoperative chemoradiation was 41 months and 34 months in preoperative chemotherapy group (p-value −0.812). Seven of 41 patients (17.1%) in chemoradiation group were circumferential resection margin (CRM) positive as compared with six of 28 (21.4%) in chemotherapy group (p = 0.650). A pathological complete response was seen in 13 (31.7%) patients in chemoradiation group and seven (21.4) patients in chemotherapy group. There was no survival advantage for preoperative chemoradiotherapy compared with preoperative chemotherapy in patients with predominant esophageal squamous cell carcinoma of locally advanced esophageal cancer. Despite the non-significant improvement from preoperative chemoradiation with respect to CRM positivity and pathological complete response rates, there was no difference in overall survival or disease-free survival.

Front Pharmacol 2022; 13:796538. [PMID: 35795555 PMCID: PMC9252455 DOI: 10.3389/fphar.2022.796538] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 04/27/2022] [Indexed: 11/25/2022] Open
Abstract
Background The use of gastric acid suppressants (GASs) has an influence on the exposure of some epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) and therefore may affect the effectiveness and safety of EGFR-TKIs. The impact of GASs, including proton pump inhibitors (PPIs) and histamine type 2 receptor antagonists (H2RAs), on the effectiveness and safety of EGFR-TKIs remains unclear. We conducted a meta-analysis to explore the impact of GASs on the effectiveness and safety of EGFR-TKIs in non–small cell lung cancer (NSCLC) patients. Method We searched the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases thoroughly from inception to 2nd February 2021, including the studies for NSCLC patients who used GASs, offering the adjusted hazard ratio (HR) of effectiveness outcomes such as overall survival (OS) and progression-free survival (PFS) or adjusted odds ratio (OR) of the adverse drug reaction (ADRs), and the results were calculated with a random effect. Two researchers independently screened the literature, extracted data, and evaluated the quality. Stata 15.0 was used for meta-analysis. Result Twelve studies were finally included. Nine of them were cohort studies, and three of them were case–control studies. For effectiveness outcomes, the use of GASs was associated with shorter PFS (HR 1.66 [1.40, 1.98]) and OS (HR 1.50 [1.31, 1.72]), and the use of PPIs was associated with shorter OS (HR 1.56 [1.21, 2.02]), regardless of the overlap time and type of EGFR-TKIs. For safety outcomes, the use of GASs (OR 1.98 [1.19, 3.31]) or PPIs (OR 1.91 [1.17, 3.12]) were both associated with an increased risk of hepatotoxicity. Conclusion The concomitant use of GASs is associated with shorter PFS and OS for NSCLC patients taking EGFR-TKIs and is also associated with a higher risk of hepatotoxicity. The co-administration of GASs should be avoided; if they cannot be avoided, H2RAs is a better choice.

Expatiating the Pharmacological and Nanotechnological Aspects of the Alkaloidal Drug Berberine: Current and Future Trends. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27123705. [PMID: 35744831 PMCID: PMC9229453 DOI: 10.3390/molecules27123705] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 06/03/2022] [Accepted: 06/07/2022] [Indexed: 12/12/2022]
Abstract
Traditionally, herbal compounds have been the focus of scientific interest for the last several centuries, and continuous research into their medicinal potential is underway. Berberine (BBR) is an isoquinoline alkaloid extracted from plants that possess a broad array of medicinal properties, including anti-diarrheal, anti-fibrotic, antidiabetic, anti-inflammatory, anti-obesity, antihyperlipidemic, antihypertensive, antiarrhythmic, antidepressant, and anxiolytic effects, and is frequently utilized as a traditional Chinese medicine. BBR promotes metabolisms of glucose and lipids by activating adenosine monophosphate-activated protein kinase, stimulating glycolysis and inhibiting functions of mitochondria; all of these ameliorate type 2 diabetes mellitus. BBR has also been shown to have benefits in congestive heart failure, hypercholesterolemia, atherosclerosis, non-alcoholic fatty liver disease, Alzheimer’s disease, and polycystic ovary syndrome. BBR has been investigated as an interesting pharmacophore with the potential to contribute significantly to the research and development of novel therapeutic medicines for a variety of disorders. Despite its enormous therapeutic promise, the clinical application of this alkaloid was severely limited because of its unpleasant pharmacokinetic characteristics. Poor bioavailability, limited absorption, and poor water solubility are some of the obstacles that restricted its use. Nanotechnology has been suggested as a possible solution to these problems. The present review aims at recent updates on important therapeutic activities of BBR and different types of nanocarriers used for the delivery of BBR in different diseases.

Abstract
BACKGROUND Although smoking is the primary risk factor for lung cancer, 15-25% of lung cancers occur in never smokers. Emerging evidence suggests lifestyle factors are associated with lung cancer risk, but few studies among never smokers exist. METHODS A case-control study of never smokers within the Canadian Partnership for Tomorrow's Health was conducted. At recruitment, participants provided data on lifestyle, health history and sociodemographic factors. Incident lung cancers were identified through linkage with administrative health records. Cases (n = 190) were matched to controls (n = 760) on age, sex, and follow-up time. Logistic regression analyses, adjusted for matching factors and annual income, were used to identify associations between lifestyle factors and lung cancer risk. RESULTS Consumption of < 5 servings of fruits and vegetables/day was associated with higher risk of lung cancer (OR 1.50, 95% CI 1.03-2.17). Short or long sleep (≤ 6 or > 9 h/night) was also associated with increased risk of lung cancer (OR 1.52, 95% CI 1.01-2.29). No associations were observed for obesity measures, alcohol consumption, or physical activity. CONCLUSION Our findings provide evidence of a potential role between sleep, fruits and vegetable consumption, and lung cancer risk in a pan-Canadian, non-smoking population. However, the sample size is modest, and further investigation is needed.

Abstract
BACKGROUND The Sydney system offers a standard biopsy protocol for detection and follow-up of gastric preneoplastic lesions such as intestinal metaplasia (IM). The highest frequency of cardia-type gastric adenocarcinoma (GA) in Iran has been documented in the north-western part of the country. This study aims to investigate the effect of the addition of mucosal biopsies of gastric cardia to the standard Sydney protocol on the rate of detection of IM in the asymptomatic residents of this high-risk region for proximal gastric cancer. METHODS A retrospective new analysis was performed on the previous data obtained in cross-sectional endoscopic screening in 2000 as well as a biopsy study of 508 asymptomatic volunteer residents in Meshkinshahr district, Ardabil province. The screening study was conducted in a group of residents aged 40 years and older who did not have any previous GI or hemodynamic problems. RESULTS Intestinal metaplasia at the Sydney protocol sampling sites was detected in 107 samples belonging to 76 of the 508 (14.99%) volunteers. Twenty-one patients had IM at the cardia. Of these, five patients had IM-cardia (IM only at the cardia). Therefore, adding a cardia biopsy to the set of biopsies diagnosed five more IM cases which were not diagnosed on the standard Sydney protocol (P=0.062). CONCLUSION The addition of a biopsy from the cardia to the Sydney protocol biopsy set does not seem to improve the frequency of detection of IM in the residents of this high-risk geographic area for proximal gastric carcinoma.

Abstract
Background The existence of hepatic cancer stem cells (CSCs) contributes to chemotherapy resistance and cancer recurrence after treatment or surgery. However, very little is known about the hepatitis B virus (HBV) replication and its relationship with the stemness of hepatocellular carcinoma (HCC) in HBV-related HCC patients. Methods We collected tumor tissues (T), matched adjacent non-tumor tissues (NT), and distal non-tumor tissues (FNT) from 55 HCC patients for analysis. Results We found HBV DNA levels were higher in T samples than NT and FNT samples, but HBV pgRNA and total RNA expressed lower in T samples. HBV pgRNA and total RNA correlate to HBV DNA among the T, NT, and FNT samples. Further evidence for HBV replication in T samples was provided by HBV S, reverse transcriptase, and X genes sequencing, showing that HBV sequences and genotypes differed between T and matched NT and FNT samples. HBV pgRNA and total RNA showed more frequent significant correlations with CSC markers in NT samples in HBsAg-positive patients. The markers CD133 and OCT4 expressed higher in FNT samples, and HBV replication marker of pgRNA levels was significantly positively correlated to these two markers only in FNT samples. The detection of pgRNA and OCT4 in FNT was correlated to the recurrence of HCC in the resection of HCC patients. Analysis of HBV receptor, sodium taurocholate co-transporting polypeptide (NTCP), showed that NTCP was correlated negatively to CSC markers in T samples, except for the CD44. Conclusion HBV replication may present in HCC with a weak transcriptomic signature. Moreover, the expression level of HBV pgRNA in distal non-tumor tissues is a sensitive marker for HBV replication and prognosis, which is associated with CSC-related markers especially with OCT4 in distal non-tumor tissues and recurrence of HCC in HBV-related HCC patients.

Abstract
Breast cancer is now the commonest cancer in most sub-Saharan African countries. Few studies of the epidemiology and genomics of breast cancer and its molecular subtypes in these countries have been done. The African Female Breast Cancer Epidemiology (AFBRECANE) study, a part of the Human Heredity and Health in Africa (H3Africa) initiative, is designed to study the genomics and epidemiology of breast cancer and its molecular subtypes in Nigerian women. We link recruitment of breast cancer cases at study sites with population-based cancer registries activities to enable ascertainment of the incidence of breast cancer and its molecular subtypes. We use centralized laboratory processing to characterize the histopathological and molecular diagnosis of breast cancer and its subtypes using multiple technologies. By combining genome-wide association study (GWAS) data from this study with that generated from 12,000 women participating in our prospective cohort study of cervical cancer, we conduct GWAS of breast cancer in an entirely indigenous African population. We test associations between dietary intakes and breast cancer and focus on vitamin D which we measure using dietary intakes, serum vitamin D, and Mendelian randomization. This paper describes the AFBRECANE project, its design, objectives and anticipated contributions to knowledge and understanding of breast cancer.

Laparotomic radical hysterectomy versus minimally invasive radical hysterectomy using vaginal colpotomy for the management of stage IB1 to IIA2 cervical cancer: Survival outcomes. Medicine (Baltimore) 2022; 101:e28911. [PMID: 35212297 PMCID: PMC8878615 DOI: 10.1097/md.0000000000028911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 02/02/2022] [Indexed: 11/26/2022] Open
Abstract
This study compared survival outcomes for patients with stage IB1 to IIA2 (International Federation of Gynecology and Obstetrics stage 2009) cervical cancer who underwent open radical hysterectomy (ORH) versus those who underwent minimally invasive radical hysterectomy (MIRH) using vaginal colpotomy (VC).Data for 550 patients who were diagnosed with cervical cancer at our institution during the period August 2005 to September 2018 was retrospectively reviewed. Of these, 116 patients who underwent radical hysterectomy (RH) were selected after applying the exclusion criteria. All MIRH patients underwent VC. Clinicopathological characteristics and survival outcomes between the ORH and MIRH groups were compared using appropriate statistical testing.Ninety one patients were treated with ORH and 25 with MIRH during the study period. Among the MIRH patients, 18 underwent laparoscopy-assisted radical vaginal hysterectomy and 7 underwent laparoscopic RH. Preoperative conization was performed more frequently in MIRH patients than in ORH patients (44% vs 22%, respectively, P = .028). The incidence of lymph node invasion was higher in the ORH group than in MIRH group (37.4% vs 12.0% respectively; P = .016). Following RH, ORH patients underwent adjuvant treatment more frequently than MIRH patients (71.4% vs 56.0%, respectively, P = .002). There were no significant differences between ORH and MIRH patients for either progression-free survival (PFS) (91.3% vs 78.7%, respectively; P = .220) or 5-year overall survival (OS) (96.6% vs 94.7%, respectively, P = .929). In univariate analysis, lympho-vascular space invasion was the only clinicopathological feature associated with decreased PFS. No other clinicopathological factors was significantly associated with PFS or OS in univariate and multivariate analyses.Despite a higher incidence of unfavorable prognostic factors in ORH patients, their survival outcomes were not different to those of MIRH patients with VC.

Abstract
BACKGROUND Cervical cancer is the fourth most common cancer that occurs to women worldwide. This study aims to assess trends in incidence and mortality of cervical cancer in India and its states over past three decades for tracking the progress of strategies for the prevention and control of cervical cancer. METHODS Data on cervical cancer incidence and mortality from 1990 to 2019 for India and its states were extracted from Global Burden of Disease study and were utilized for the analysis. Spatial and rank map has been used to see the changes in incidence and mortality of cervical cancer in different Indian states. Further, joinpoint regression analysis is applied to determine the magnitude of the time trends in the age standardized incidence and mortality rates of cervical cancer. We obtained the average annual percent change (AAPC) and corresponding 95% confidence intervals (CI) for each state. RESULTS Overall, from 1990 to 2019 Jharkhand (Incidence: -50.22%; Mortality: -56.16%) recorded the highest percentage decrement in cervical cancer incidence and mortality followed by the Himachal Pradesh (Incidence: -48.34%; Mortality: -53.37%). Tamilnadu (1st rank), Jammu & Kashmir and Ladakh (32nd rank) maintained the same rank over the period of three decade for age standardized cervical cancer incidence and mortality. The regression model showed a significant declining trend in India between 1990 and 2019 for age standardized incidence rate (AAPC: -0.82; 95%CI: -1.39 to -0.25; p < 0.05) with highest decline in the period 1998-2005 (AAPC: -3.22; 95%CI: -3.83 to -2.59; p < 0.05). Similarly, a significant declining trend was observed in the age standardized mortality rate of India between 1990 and 2019(AAPC: -1.35; 95%CI: -1.96 to -0.75; p < 0.05) with highest decline in the period 1998-2005 (AAPC: -3.52; 95%CI: -4.17 to -2.86; p < 0.05). CONCLUSION Though the incidence and mortality of cervical cancer declined over past three decades but it is still a major public health problem in India. Information, education and communication activities for girls, boys, parents and community for the prevention and control of cervical cancer should be provided throughout the country.

Abstract
Photoinduced hyperthermia is a cancer therapy technique that induces death to cancerous cells via heat generated by plasmonic nanoparticles. While previous studies have shown that some nanoparticles can be effective at killing cancer cells under certain conditions, there is still a necessity (or the need) to improve its heating efficiency. In this work, we perform a detailed theoretical study comparing the thermoplasmonic response of the most effective nanoparticle geometries up to now with a doughnut-shaped nanoparticle. We numerically demonstrate that the latter exhibits a superior tunable photothermal response in practical illumination conditions (unpolarized light). Furthermore, we show that nanoparticle heating in fluidic environments, i.e., nanoparticles undergoing Brownian rotations, strongly depends on the particle orientation with respect to the illumination source. We conclude that nanodoughnuts are the best nanoheaters in our set of structures, with an average temperature increment 40% higher than the second best nanoheater (nanodisk). Furthermore, nanodoughnuts feature a weak dependence on orientation, being therefore ideal candidates for photothermal therapy applications. Finally, we present a designing guide, covering a wide range of toroid designs, which can help on its experimental implementation.

Abstract
Abstract
Background Gastric cancer (GC) is one of the most common malignancies and a leading cause of mortality and morbidity worldwide. It is the fourth leading cancer in Bangladesh. Identification of risk factors, effective prevention, and early diagnosis are the most important interventions against GC.
Objectives To find an association of dietary and behavioral factors in the development of GC among the Bangladeshi population.
Methods This case–control study was conducted from January 2017 to December 2018 at the National Institute of Cancer Research and Hospital, Dhaka, Bangladesh. A total of 178 patients were studied (89 case and 89 controls). Data were collected via face-to-face interview using a standard structured questionnaire, posing questions about socio-demographic, behavioral and dietary habits, and clinical factors. A binary logistic regression method was used to calculate the odds ratio (OR).
Results Among 178 patients, the age group ranged from 30 to 80 years and most patients were between 51 to 60 years. The results showed that regular consumption of red meat, duration of smoking, smokeless tobacco, fast food and fatty food, and family history of any type of cancer were directly associated with the risk of GC. On the contrary, a habit of regular walking and playing sports has an inverse association with GC. Adjusted OR shows regular consumption of red meat has 2.6 times more risk (OR = 2.661) of developing GC compared with irregular meat consumption, and a person with a history of Helicobacter pylori infection is 53% (OR = 7.263; 95% confidence interval: 3.614–14.597) more likely to develop cancer. In contrast, people who were doing exercise regularly for at least 30 minutes/day are 62.7% (OR = 0.373) less likely to develop GC than those who did not.
Conclusion The study showed an association of some dietary and behavioral factor in the development of GC. However, more research in this field is required to understand the etiology, for the development of suitable screening test, for demarcation of high-risk population, and to develop and evaluate the effectiveness of primary prevention programs.

Abstract
BACKGROUND Jejunal feeding is an invaluable method by which to improve the nutritional status of patients undergoing neoadjuvant and surgical treatment of oesophageal malignancies. However, the insertion of a feeding jejunostomy can cause significant postoperative morbidity. The aim of this study is to compare the outcomes of patients undergoing placement of feeding jejunostomy by conventional laparotomy with an alternative laparoscopic approach. METHODS A retrospective review of data prospectively collected at the Oxford Oesophagogastric Centre between August 2017 and July 2019 was performed including consecutive patients undergoing feeding jejunostomy insertion. RESULTS In the study period, 157 patients underwent jejunostomy insertion in the context of oesophageal cancer therapy, 126 (80%) by open technique and 31 (20%) laparoscopic. Pre-operative demographic and nutritional characteristics were broadly similar between groups. In the early postoperative period jejunostomy-associated complications were noted in 54 cases (34.4%) and were significantly more common among those undergoing open as compared with laparoscopic insertion (38.1% vs. 19.3%, P = 0.049). Furthermore, major complications were more common among those undergoing open insertion, whether as a stand-alone or at the time of staging laparoscopy (n = 11/71), as compared with insertion at the time of oesophagectomy (n = 3/86, P = 0.011). CONCLUSIONS This report represents the largest to our knowledge single-centre comparison of open vs. laparoscopic jejunostomy insertion in patients undergoing oesophagectomy in the treatment of gastroesophageal malignancy. We conclude that the laparoscopic jejunostomy insertion technique described represents a safe and effective approach to enteral access which may offer superior outcomes to conventional open procedures.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most important causes of cancer-related death. miR-1181 has been reported to have roles in various cancer types and its function in the progression of NSCLC was investigated in the present study. A total of 118 patients with NSCLC were recruited and their tumor tissues were collected. The expression of miR-1181 in NSCLC tissues and cells was detected by reverse transcription-quantitative PCR. The prognostic value of miR-1181 was evaluated by Kaplan-Meier and Cox regression analysis and the roles of miR-1181 in cell proliferation, migration and invasion of NSCLC were analyzed by Cell Counting Kit-8 and Transwell assays. miR-1181 was indicated to be upregulated in NSCLC tissues and cell lines, and to be associated with lymph node metastasis and the TNM stage of patients. Patients with high miR-1181 expression had a poorer prognosis than those with low miR-1181 expression. miR-1181 levels and TNM stage were determined to be two independent prognostic factors for NSCLC. In addition, overexpression of miR-1181 exerted enhancing effects on cell proliferation, migration and invasion of NSCLC, while its knockdown inhibited these cellular processes. In conclusion, upregulation of miR-1181 in NSCLC was associated with lymph node metastasis and TNM stage of patients and was indicative of poor prognosis. miR-1181 was indicated to exert promoting effects on cell proliferation, migration and invasion of NSCLC cells and to be involved in tumor progression, providing novel insight for the development of biomarkers and therapies for NSCLC.

Abstract
Objective: Hungary has one of the highest incidences and mortality rates of lung cancer (LC), therefore the objective of this study was to analyse and compare LC incidence and mortality rates between the main Hungarian regions. Methods: This nationwide, retrospective study used data from the National Health Insurance Fund and included patients aged ≥20 years who were diagnosed with lung cancer (ICD-10 C34) between Jan 1, 2011 and Dec 31, 2016. Age-standardized incidence and mortality rates were calculated and compared for the main regions. Results: The highest incidence rate in males was recorded in Northern Hungary (146.8/100,000 person-years [PY]), while the lowest rate was found in Western Transdanubia (94.7/100,000 PY in 2011). All rates showed a declining trend between 2011 and 2016, with the largest decrease in the Northern Great Plain (−20.0%; p = 0.008). LC incidence and mortality rates in women both showed a rising tendency in all regions of Hungary, reaching the highest in Central Hungary (59.86/100,000 PY in 2016). Lung cancer incidence and mortality rates in males correlated with the level of education and smoking prevalence (p = 0.006 and p = 0.01, respectively) in the regions. A correlation with GDP per capita and Health Development Index (HDI) index could also be observed in the Hungarian regions, although these associations were not statistically significant. No correlations could be detected between these parameters among females. Conclusion: This analysis revealed considerable differences in the epidemiology of LC between the 7 main Hungarian regions. LC incidence and mortality rates significantly correlated with smoking and certain socioeconomic factors in men, but not in women. Further research is needed to explain the regional differences.

Abstract
Helicobacter pylori (H. pylori) is a major causative agent of chronic gastritis, gastric ulcer and gastric carcinoma. H. pylori cytotoxin associated antigen A (CagA) plays a crucial role in the development of gastric cancer. Gastric cancer is associated with glycosylation alterations in glycoproteins and glycolipids on the cell surface. H. pylori cytotoxin associated antigen A (CagA) plays a significant role in the progression of gastric cancer through post-translation modification of fucosylation to develop gastric cancer. The involvement of a variety of sugar antigens in the progression and development of gastric cancer has been investigated, including type II blood group antigens. Lewis Y (LeY) is overexpressed on the tumor cell surface either as a glycoprotein or glycolipid. LeY is a difucosylated oligosaccharide, which is catalyzed by fucosyltransferases such as FUT4 (α1,3). FUT4/LeY overexpression may serve as potential correlative biomarkers for the prognosis of gastric cancer. We discuss the various aspects of H. pylori in relation to fucosyltransferases (FUT1-FUT9) and its fucosylated Lewis antigens (LeY, LeX, LeA, and LeB) and gastric cancer. In this review, we summarize the carcinogenic effect of H. pylori CagA in association with LeY and its synthesis enzyme FUT4 in the development of gastric cancer as well as discuss its importance in the prognosis and its inhibition by combination therapy of anti-LeY antibody and celecoxib through MAPK signaling pathway preventing gastric carcinogenesis.

J Cell Biochem 2021; 123:161-182. [PMID: 34520596 DOI: 10.1002/jcb.30143] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 07/23/2021] [Accepted: 08/24/2021] [Indexed: 12/15/2022]
Abstract
Viruses are known to cause various diseases in human and also infect other species such as animal plants, fungi, and bacteria. Replication of viruses depends upon their interaction with hosts. Human cells are prone to such unwanted viral infections. Disintegration and reconstitution require host machinery and various macromolecules like DNA, RNA, and proteins are invaded by viral particles. E3 ubiquitin ligases are known for their specific function, that is, recognition of their respective substrates for intracellular degradation. Still, we do not understand how ubiquitin proteasome system-based enzymes E3 ubiquitin ligases do their functional interaction with different viruses. Whether E3 ubiquitin ligases help in the elimination of viral components or viruses utilize their molecular capabilities in their intracellular propagation is not clear. The first time our current article comprehends fundamental concepts and new insights on the different viruses and their interaction with various E3 Ubiquitin Ligases. In this review, we highlight the molecular pathomechanism of viruses linked with E3 Ubiquitin Ligases dependent mechanisms. An enhanced understanding of E3 Ubiquitin Ligase-mediated removal of viral proteins may open new therapeutic strategies against viral infections.

Song J, Xu J, Guo J, Shang Y, Wang J, Wang T. The enhancement of Tetrandrine to gemcitabine-resistant PANC-1 cytochemical sensitivity involves the promotion of PI3K/Akt/mTOR-mediated apoptosis and AMPK-regulated autophagy. Acta Histochem 2021; 123:151769. [PMID: 34416437 DOI: 10.1016/j.acthis.2021.151769] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 07/28/2021] [Accepted: 08/08/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND In the process of tumor development, the resistance of pancreatic cancer cells to gemcitabine (GEM) is mainly due to the suppression and dysregulation of apoptosis signals to a large extent. Therefore, it is very necessary to develop pro-apoptotic drugs for combined treatment of pancreatic cancer to increase the activity of GEM and improve the prognosis of pancreatic cancer. METHODS AND RESULTS GEM-resistant PANC-1 cells were treated with increasing doses of GEM. The effects of GEM and TET on apoptosis were evaluated by flow cytometry and Hoechst 33258 staining. We also evaluated the expression of survivin by real-time PCR, and the expression levels of proteins involved in apoptosis, autophagy, and PI3K/Akt/mTOR signaling were detected by western blotting. The results showed that TET downregulated expression of survivin by inhibiting the PI3K/Akt/mTOR signaling pathway to promote pancreatic cancer cell apoptosis, thereby enhancing pancreatic cancer cell sensitivity to GEM. Moreover, TET enhanced cytotoxic and autophagy-dependent cell death by upregulating the AMPK-autophagy axis, and this effect was reversed by inhibition of AMPK. CONCLUSIONS TET promotes apoptosis by inhibiting the PI3K/Akt/mTOR signaling pathway and promotes autophagy via up-regulating the AMPK signaling pathway to play an anti-tumor effect in GEM-resistant pancreatic cancer cells, which represents a new therapeutic strategy for the treatment of GEM-resistant pancreatic cancer.

Abstract
X-inactive-specific transcript (XIST) is a 19 kb noncoding RNA which is oncogenic in many cancers including gastric cancer. It is reported that XIST contributes to gastric cancer cells resistant to cisplatin, but specific mechanisms governing this resistance remain unclear. We firstly examined the XIST level in gastric cancer cells and tumor specimens. We confirmed that XIST is overexpressed in gastric cancer cells and tumors, which further contributed to the poor prognosis of patients with gastric cancer. We also confirmed that high XIST level contributes to the cisplatin resistance in gastric cancer cells. Subsequently, we predicted microRNAs that have the potential to interact with XIST and found that Let-7b-5p may directly interact with XIST. We confirmed the direct interaction between XIST and Let-7b-5p and identified a negative correlation between the level of Let-7b-5p and XIST in gastric cancer tumors. Meanwhile, Let-7b-5p inhibitor treatment can partially rescued the effect of XIST-specific small interfering RNA on cell proliferation and apoptosis by regulating Aurora kinase B expression. XIST functions as an oncogene in gastric cancer which contributes to the cisplatin resistance by interacting with Let-7b-5p.

Abstract
BACKGROUND Prostate cancer is considered the second most diagnosed cancer, and one of the most common causes of death from cancer in men. Apalutamide is an effective, safe, and well-tolerated agent used for the treatment of men with non-metastatic castration-resistant prostate cancer (nmCRPC) and metastatic hormone-naive prostate cancer (mHNPC). Androgen receptor signaling is a leading factor that drives these prostate tumors. USFDA has approved apalutamide on 14 February 2018 as an agent that targets androgen receptor signaling through inhibition causing significant improvement in metastasis-free survival in patients with prostate cancer. <P> Objective: In this review, various aspects related to apalutamide have been summarized which involve the mechanism of action, chemistry, synthesis, pharmacokinetics, pharmacodynamics, adverse reactions, and safety parameters. <P> Methods: The literature was thoroughly searched in the relevant databases to identify studies published in this field during recent years. Special attention has been given to apalutamide clinical trials phases and its promising future as one of the first-line agents for the treatment of patients with advanced prostate cancer. <P> Results: Ongoing trials are progressing for apalutamide monotherapy and also for its combinations in other disease settings. The expected results of such trials will shape the future scenario of prostate cancer therapy. <P> Conclusion: This review article has highlighted different aspects of Apalutamide like its mechanism of action, adverse effects, pharmacokinetics, pharmacodynamics, clinical trials among others. The contents of this article should make an excellent read for prospective researchers in this field.

Cancer Epidemiol 2021; 74:102009. [PMID: 34399245 DOI: 10.1016/j.canep.2021.102009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 08/06/2021] [Accepted: 08/07/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Breast cancer is the most common malignancy in women world-wide and the most common cause of cancer deaths, which can often be managed with early diagnosis and subsequent treatment. Here, we focus on geographic disparities in incidence within Portugal for three age groups of women (30-49; 50-69; 70-84 years). METHODS Age-period-cohort (APC) models are widely used in cancer surveillance, and these models have recently been extended to allow spatially-varying effects. We apply novel spatial APC models to estimate relative risk and age-adjusted temporal trends at the district level for the 20 districts in Portugal. Our model allows us to report on country-wide trends, but also to investigate geographic disparities between districts and trends within districts. RESULTS Age-adjusted breast cancer incidence was increasing over 1998-2011 for all three age groups and in every district in Portugal. However, we detect spatially-structured between-district heterogeneity in relative risk and age-adjusted trends (Net Drifts) for each of the three age groups, which is most pronounced in the highly-screened (50-69yo) and late-onset (70-84yo) groups of women. CONCLUSIONS We present evidence of disparities in breast cancer incidence at a more granular geographic level than previously reported. Some disparities may be due to latent risk factors, which cannot be accounted for by age, birth year, and geographic location alone. IMPACT Our study motivates resuming data collection for breast cancer incidence at the district level in Portugal, as well as the study of exogenous risk factors.

Abstract
PURPOSE To generate and present the survey results on critical issues relevant to screening, diagnosis, and staging tools for prostate cancer (PCa) focused on developing countries. METHODS A total of 36 of 300 questions concern the main areas of interest of this paper: (1) screening, (2) diagnosis, and (3) staging for various risk levels of PCa in developing countries. A panel of 99 international multidisciplinary cancer experts voted on these questions to create recommendations for screening, diagnosing, and staging tools for PCa in areas of limited resources discussed in this manuscript. RESULTS The panel voted publicly but anonymously on the predefined questions. Each question was deemed consensus if 75% or more of the full panel had selected a particular answer. These answers are based on panelist opinion not a literature review or meta-analysis. For questions that refer to an area of limited resources, the recommendations consider cost-effectiveness and the possible therapies with easier and greater access. Each question had five to seven relevant answers including two nonanswers. The results were tabulated in real time. CONCLUSION The voting results and recommendations presented in this document can be used by physicians to support the screening, diagnosis, and staging of PCa in areas of limited resources. Individual clinical decision making should be supported by available data; however, as guidelines for screening, diagnosis, and staging of PCa in developing countries have not been developed, this document will serve as a point of reference when confronted with this disease.

Abstract
BACKGROUND Prostate cancer is the second most common cancer in men and sixth leading cause of mortality. If not recognized early, patients with advanced prostate cancer can experience debilitating complications which can otherwise be prevented by early androgen deprivation therapy. This research intends to define clear diagnostic tools that will guide practitioners in the rural community setting toward early management of advanced prostate cancer. METHODS We conducted a cross-sectional observational study at three referral hospitals in Kigali, Rwanda on patients who presented with clinical suspicion of advanced prostate cancer over a period of 6 months. All patients underwent prostate biopsy as well as metastatic work up (CT or MRI), for those who were eligible. Statistical analysis was done using STATA 14.2. RESULTS 114 patients were included in the study. The median age was 70 years (interquartile range: 65-79 years). In total 14 (12.3%) patients were found to have benign disease, while 100 (87.7%) patients were found to have cancer. Among those who had cancer, 85 (85%) had advanced prostate cancer. 110/114 (96.5%) were symptomatic at presentation. Common presenting symptoms were lower urinary tract symptoms (80.7%), back pain (54.4%), and urinary retention (36.8%). Abnormal digital rectal examination (DRE) was a strong risk factor for both cancer and advanced disease. Prostate cancer was found in 92.2% of those with abnormal DRE compared to 41.7% in those with normal DRE (p = 0.001). Also, cancer was found in 96.1% of those with multinodular prostate on DRE (p = 0.02) and had high odds (OR 14.6; CI 3.41-62.25) of having advanced prostate cancer (p < 0.001). The mean (± SD) PSA was 643.3 ± 1829.8 ng/ml and the median (range) was 100 ng/ml (9.05-10,000 ng/ml) for the whole study population. All patients with prostatic-specific antigen (PSA) of 100 ng/ml or above had advanced prostate cancer. CONCLUSION The results show that there is a significant correlation between clinical findings and advanced prostate cancer. All patients with abnormal DRE and PSA above 100 ng/ml had advanced prostate cancer. Diagnosis of advanced prostate cancer is possible at the community level if PSA testing is utilized and practitioners are well trained.

Abstract
AIM Being the common cause and major burden of deaths globally, timely management of cancer is crucial. BACKGROUND Thymic immunosuppressive pentapeptide (TIPP) is a novel pentapeptide originally obtained from calf thymic immunosuppressive extract. Previously, TIPP has been proved to suppress the allergic and inflammatory responses in allergic mice via blocking MAP kinases/NF-κB signaling pathways. OBJECTIVE In this study, in vitro anticancer activity of TIPP was tested on two different types of cancers using MCF-7 and K562 cell lines. METHODS Tumor xenograft models for breast cancer and chronic myeloid leukemia were designed. In vivo anticancer activity of TIPP was investigated on both cancer types. The liver and tumor tissues of the mice were preserved for immunohistochemistry analysis. RESULTS In vitro anticancer activity of TIPP showed significant inhibition on cell viability of both breast cancer and chronic myeloid leukemia. In vivo anticancer effect of TIPP in both types of cancer models further proved the potent anticancer nature of TIPP. Immunohistochemistry analysis assured that TIPP is a safe drug for normal organs such as the liver. CONCLUSION Our present study revealed that TIPP is a potent anticancer drug and an important treatment option for various diseases. Further work is needed to test the flexible and proficient activity of the novel peptide.
