The aim of this study is to assess the current level of knowledge, as well as the attitudes and practices (KAP) of the adult population in Sharjah, UAE with regards to H. pylori induced gastric ulcers and gastric cancers.

A cross sectional study of 500 participants was conducted in public venues in Sharjah, UAE through the distribution of a self-administered questionnaire English and Arabic speaking residents aged 18 years and above of both sexes were invited to participate in this study via convenience sampling. Responses were collected and analyzed using SPSS.

General knowledge about H. pylori was poor, only 24.6% had heard of H. pylori. 61% of the participants did not know the link between H. pylori and gastric cancer. Only 3% of the participants associated psychological stress with gastric ulcer development. Females had higher knowledge scores (p = 0.008*). Participants with a medical background typically had higher knowledge scores than their peers in other fields of work (p < 0.0001*). Participants' attitudes towards H. pylori were suboptimal with only 33% willing to seek medical help If they get symptoms. Majority of participants with an approximate of 84% showed an overall average to excellent practices towards H. pylori.

General awareness about H. pylori induced gastric ulcers and cancers is poor. The results of this study can be a starting point to devise new education programs and campaigns that raise awareness of this health issue which could be easily avoided with prevention, early detection, and intervention.<br />.

The side effects of conditioning regimens on the success rate of allogeneic transplantation around the world have been challenging. In this study, we aimed to investigate the side effect of Bu/Cy and Bu/Flu regimens on our patients who underwent allogeneic bone marrow transplantation.

We analyzed 180 patients receiving bone marrow transplantation in Taleghani Hospital, in Tehran, Iran between April 2016 and December 2019. Patients in group A received a combination of intravenous busulfan 0.8 mg/kg QID over two hours for 4 consecutive days (12.8 mg/kg in total)(Savani et al., 2006) and cyclophosphamide 60 mg/kg per day for two consecutive days. Patients in group B received busulfan the same as the first group in combination with fludarabine equal to 40 mg/m² per day. Patients were followed up at regular intervals up to two years after transplantation.

Various items were evaluated for patients, including cardiopulmonary function, psychological disorders, GVHD, and endocrine disorders such as hypothyroidisitioning regimens in patients who underwent allogeneic bone marrow transplant were almost similar. To improve quality of life and overall survival among BMT patients, careful evaluation of treatment-related complications should be part of the regular follow-up of them.

In loco regionally advanced head and neck cancer, the superiority of concomitant cetuximab with radiation over radiation alone has been proven previously. But comparison between chemo radiation and bioradiation has not been well studied.

Between October 2013 and August 2017, 38 patients with locoregionally advanced laryngeal cancer and more than 50% response to 3 cycles of induction chemotherapy (docetaxel and cisplatin both with a dose of 75 mg/m2 on the first day and 5-flurouracil 750 mg/m2 during days 1to 3; repeated every 21 days) were selected to receive either carboplatin (18 patients, AUC 1.5 , weekly) or cetuximab (20 patients, with loading dose of 400 mg/m2 and weekly dose of 250 mg/m2) with radiation. A Kaplan-Meier analysis was used to calculate progression free survival and overall survival rates. The log-rank test was used to compare overall survival between treatment groups.

The median follow up time was 36 months. The 2-year organ preservation rate of 78.9% was achieved. The 3- year progression-free survival rates of 65.2%, 72.7% and 58.2% were observed for all patients, carboplatin group and cetuximab group, respectively (p=0.4). The 3-year estimates of overall survival were 67.8%, 69.2 %, and 66.3 % for all patients, carboplatin group and cetuximab group, respectively (p=0.47). Concomitant carboplatin was discontinued in 3 patients due to toxicity Conclusion Concomitant cetuximab is a reasonable alternative to concomitant chemotherapy. But the difference in treatment outcome between bioradiation and chemoradiation remains to be defined.<br />.

Rosmarinic acid (RA) is a natural phenolic compound that acts as a Fyn inhibitor by 53 homology modeling of the human Fyn structure. GSK1016790A Therefore, the apoptosis mechanism related to NF-κB signaling pathway induced by RA in HepG2 was investigated.

The cell growth, apoptosis, and proliferation of HepG2 regulated by various concentrations of RA were studied. The proteins expression of MMP-2, MMP-9, PI3K, AKT, NF-κB, and apoptosis-related proteins Bax, Bcl-2, cleaved caspase-3 were detected.

RA significantly reduced proliferation rates, inhibited migration and invasion, and decreased the expressions of invasion-related factors, such as matrix metalloproteinase (MMP)-2 and MMP-9. TUNEL staining revealed that RA resulted in a dose-dependent increase of HepG2 cell apoptosis. In line with this finding, the expression of apoptosis suppressor protein Bcl-2 was downregulated and that of the pro-apoptotic proteins Bax and cleaved caspase-3 was increased. In addition, we found that the phosphatidylinositol 3-kinase (PI3K)/Akt/nuclear factor kappa B (NF-κB) signaling pathway was involved in RA-mediated inhibition of HepG2 cell metastasis.

Our study identified that RA as a drug candidate for the treatment of HCC.

Our study identified that RA as a drug candidate for the treatment of HCC.Background Although survival rates for retinoblastoma (RB) are over 95% in high-income countries, its high mortality rate in low and middle-income countries remains a great concern. Few studies investigated treatment outcome and factors contributing to RB survival in these latter settings. Aims of this study are to determine treatment outcome of Indonesian children diagnosed with RB and to explore factors predictive of treatment outcome. Methods This study was a retrospective medical records review combined with an illustrative case report. Children newly diagnosed with RB between January 2011 and December 2016 at a tertiary care referral hospital in Indonesia were included. A home visit was conducted to perform an in-depth interview with a mother of two children affected by RB. Results Of all 61 children with RB, 39% abandoned treatment, 21% died, 20% had progressive or relapsed disease and 20% event-free survival. Progressive or relapsed disease was more common in older (≥ 2 years at diagnosis, 29%) than young ( less then 2 years at diagnosis, 0%) children (P=0.012). Event-free survival estimate at 5 years was higher in young (42%) than older (6%) children (P=0.045). Odds-ratio for event-free survival was 6.9 (95% CI 1.747 – 27.328, P=0.006) for young versus older children. Other clinical and socio-demographic characteristics had no significant correlation with treatment outcome or event-free survival. The case report elucidated conditions and obstacles that Indonesian families face when their children are diagnosed with RB. Conclusion Survival of children with RB in Indonesia is much lower compared to high-income and many other low and middle-income countries. Abandonment of treatment is the most common cause of treatment failure. Older age at diagnosis is associated with more progressive or relapsed disease and worse survival. Interventions to improve general public and health-care providers’ awareness, early detection and treatment adherence are required.

An accurate assessment of potential pathologic complete response(pCR) following neoadjuvant chemoradiotherapy(NCRT) is important for the appropriate treatment of rectal cancer. However, the factors that predict the response to neoadjuvant chemoradiotherapy have not been well defined. Therefore, this study analyzed the predictive factors on the development of pCR after neoadjuvant chemoradiation for rectal cancer.

From January 2008 to January 2018, a total of 432 consecutive patients from a single institution patients who underwent a long-course neoadjuvant chemoradiotherapy were reviewed in this study. The clinicopathological features were analyzed to identify predictive factors for pathologic complete response in rectal cancer after neoadjuvant chemoradiation.

The rate of pathologic complete response in rectal cancer after neoadjuvant chemoradiation was 20.8%, patients were divided into the pCR and non-pCR groups. The two groups were well balanced in terms of age, gender, body mass index, ASA score, tu rectal cancer after neoadjuvant chemoradiation. Using these predictive factors, we can predict the prognosis of patients and develop adaptive treatment strategies. A wait-and-see policy might be possible in highly selective cases.

There are limited data concerning the use of mastectomy and associated factors in China in recent years. This study aimed to investigate the uptake of mastectomy and determine the associations between patients' characteristics and mastectomy among Chinese women with breast cancer.

A retrospective analysis of female breast cancer cases from 1st January 2015 to 31st December 2019 from a tertiary hospital was conducted. Socio-demographic data, clinical data, and surgery types were collected by reviewing the medical record system. Chi-squared test, Fisher's exact test and multivariate logistic regression analysis were used to determine any correlations of patients' characteristics with mastectomy.

A total of 1,171 women with breast cancer were identified, and 76.60% of them underwent a mastectomy. The mastectomy rates showed an increase from 70.62% in 2015 to 86.87% in 2017 and then dropped to 71.91% in 2019. Women undergoing mastectomy were older and were more likely to be married and have at least one child. They had an advanced cancer stage, larger tumour size, and more lymph node invasion and were positive for HER-2 overexpression. Older age, larger tumour size (2-5 cm), higher cancer stages (stage 2- stage 3) and being positive for HER-2 were the four independent variables that significantly predicted the uptake of mastectomy.

Our results showed a wide application of mastectomy in China and uncovered the factors associated with mastectomy uptake from a single-centre experience. Findings suggested the potential overuse of mastectomy among women with early-stage breast cancer, and highlighted the significance of promoting cancer screening in China. Findings could be also used to develop relevant provisions and interventions to facilitate breast cancer treatment decision-making and screening planning.<br />.

CD133 is considered a cancer stem cell (CSC) marker in various malignancies; however, its role as a biomarker of malignant melanoma remains controversial. The present study was conducted to evaluate the suitability of CD133 surface antigen as a CSC marker in melanoma.

Human melanoma cells were fractionally separated by magnetic cell separation depending on the CD133 phenotype and transplanted into immunodeficient mice to evaluate their tumorigenic capacity. Furthermore, the time until the development of a palpable tumor and the growth rate were measured, and the final tumor volume was assessed after 8 weeks. The immunohistochemical expression of CD133 in the induced neoplasia was then compared using histomorphometry.

Notably, neoplasms were induced in all the groups (n = 48), including in the CD133-negative group. Tumors induced by unsorted cells had the largest volume (p = 0.014) but were detected significantly later in this group (p ≤ 0.001). Interestingly, all explanted tumors expressed CD133, with no significant differences among groups.
