Background: Meningioma is the most common primary intracranial tumor. Previous studies have shown the possible association between hormonal contraceptive use and meningioma location. Therefore, this study aimed to analyze the association between the history of hormonal contraceptive use and the location of meningioma in the Indonesian population. Methods: In total, 99 histologically confirmed female meningioma patients admitted to Dr. Sardjito General Hospital Yogyakarta, Indonesia, were included in this study. Data on hormonal contraception and other variables were collected from medical records. Meningioma locations were determined from brain Magnetic Resonance Imaging (MRI) or Computerized Tomography (CT) scan before surgery. Results: Seventy-two (72.7%) patients had a history of hormonal contraceptive use. The subjects consist of 83 (83.8%) WHO grade I and 16 (16.2%) WHO grade II and III tumors. A total of 57 (57.6%) tumors were located in the spheno-orbital region. We found a significant association between hormonal contraceptive use and meningioma location in the spheno-orbital region (Odds ratio (OR) 2.573, p=0.038). This resulted in the patients in the hormonal contraception group having more visual impairment (p=0.044). Conclusion: The use of hormonal contraception is associated with the location of meningioma in the spheno-orbital region.

Objective: This study aims to determine the role of beetroot extract in overcoming the chemoresistance of Neoadjuvant Adriamycin Cyclophosphamide (NAC) regimens with a target immune response in the tumour microenvironment at the pre-clinical stage. Methods: This study was conducted on rats with 7,12-Dimethyl Benz (α) Anthracene (DMBA) induced mammary adenocarcinoma. Adriamycin Cyclophosphamide was given in 4 cycles, whereas beetroot extract was administered three times each cycle. Observations of CD8 T cells and Myeloid Derivative Suppressive Cells (MDSC) expression levels and pathological responses were carried out on tumour tissue taken at the end of the observation. Results: Supplementation of beetroot extract to NAC could significantly increase CD8 T cells and decrease MDSC in the tumour microenvironment. The addition of beetroot extract gave a better pathological response. Conclusion: Beetroot extract enhances the immune response in the tumor microenvironment so that it has the potential to overcome chemoresistance in NAC.

Background: Globally, cancer is one of the main causes of death. Nonetheless, the estimate for Middle Eastern countries is high and rising. Furthermore, there is a paucity of evidence on effective rehabilitation measures for treatment of cancer patients, particularly head and neck cancer patients. As a result, the purpose of this study is to enlist current physical therapy clinical practice adopted by physiotherapists for the assessment and treatment of patients with head and neck cancer in United Arab Emirates. Methodology: A total of 100 survey questionnaires were sent via e-mail to physical therapists across the United Arab Emirates ‘s oncology rehabilitation centers for this cross-sectional study. Physical therapists having a valid license and at least one year of experience treating patients with head and neck cancer were included in the study. The collected responses were analyzed using descriptive statistics. Results: The total questionnaires generated a response rate of 56% of the targeted population. A percentage of 67% of the survey marked “Always or Frequently” by more than 50% of responders. Components aiming at the musculoskeletal system in both assessment and management were used more than those targeting the cardiopulmonary system. Functional capacity and Quality of Life measures were not given as much attention however 50% of responders reported using the Fatigue and Severity Scale (FSS). Mobilization was notably marked in management, especially Upper Extremity Training which was utilized by 86.4% of responders. Educational tips components all ranged around 40-60% except for Breathing Exercise which peaked at 85.7% of the responders. Discussion and Conclusion: Assessment measures predominantly focused on functional impairment measures of the upper limb, including functions related to mandible, tongue, mouth opening, and neck movement. Treatment patterns on the other hand predominantly centred on functionally related exercises as upper limb training, breathing exercises, and facial muscle exercise.

Objective: The present study aims to identify the effect of ZnHDACs expression on the survival of the patients. Further, reveal the unique and common genes associated with each ZnHDACs and their associated pathways. Methods: The patient data was obtained from the Cancer Genome Atlas Program (TCGA) database and was analyzed using cBioportal and Gene Expression Profiling Interactive Analysis 2(GEPIA2) online tools. Protein-protein interactions and functional interactomic analysis were done using STRING, DAVID, and KEGG pathway databases. Results: HDAC1, 2, 8, 11 were over-expressed and, HDAC4, 5, 6, 7, and 10 were down-regulated in all the cancer types, but there are few exceptional expression patterns such as HDAC7 and HDAC10 overexpression in HNSC, HDAC3 down-regulation in LUAD, and PRAD. The unique genes interacting with each ZnHDACs provided a better understanding of ZnHDAC’s putative role in carcinogenesis. The present study reported that JARID2, stem cell regulation gene uniquely interacts with HDAC1, BPTF-CHRAC-BAZIA axis, enzymes for chromatin modeling selectively interacting with only HDAC2, HDAC3 in H2A acetylation via DMAP1 and YEATS4. HDAC6 associated unique genes regulate protein stability, HDAC7 in subnuclear localization and splicing, HDAC8 in telomere maintenance, HDAC9 in chromosomal rearrangements, and HDAC11 in maintaining histone core and folding. Conclusion: The unique genes and pathways associated with a particular ZnHDACs could provide a wide window for interrogating these genes for obtaining putative drug targets.

Background: Early-stage cervical cancer diagnoses may be the consequence of timely medical care in the presence of symptoms which can be linked to awareness of the symptoms and risk factors. This study aims to determine the knowledge about risk factors and symptoms of cervical cancer and associated factors among women aged 20-49 years. Methods: Data were utilized from the survey under the intervention “Increasing access to cervical cancer screening and care through the community-centric continuum of care initiative in India” (2015). The sample size was 1,020 women in the age group of 20-49 years. Descriptive statistics, along with bivariate analysis, was done to represent the preliminary results. Multivariable regression analysis was used to represent the estimates. Results: About 40.1% [Delhi: 56.9% and Rohtak: 20.4%] and 45.5% [Delhi: 52.2% and Rohtak: 37.7%] of respondents had good knowledge about risk factors and symptoms of cervical cancer, respectively. Respondents with primary educational status had an 86% significantly higher likelihood for good knowledge about identified risk factors of cervical cancer [ adjusted odds ratio (aOR): 1.86; CI: 1.12-3.10]. Respondents who were married or widowed/divorced/separated had significantly higher odds for good knowledge about identified risk factors and symptoms of cervical cancer in reference to respondents who were never married. Respondents from Rohtak had 72% and 35% significantly higher odds for good knowledge about identified risk factors [aOR:0.28; CI: 0.21,0.39] and symptoms [aOR:0.65; CI: 0.48,0.88] of cervical cancer, respectively, in reference to respondents from Delhi. Conclusion: Overall awareness about cervical cancer and Human papillomavirus (HPV) as the causative agent was low, more so in Rohtak. This is extremely worrisome as blocking HPV infection is one of the most effective ways to prevent cervical cancer. Moreover, the knowledge about the risk factors and symptoms of cervical cancer is also inadequate, particularly in women from Rohtak.

Objective: We aimed to identify gastric cancer-related risk factors and evaluate the efficacy of screening ABC(D) method in determining high risk gastric cancer individuals in Mongolian population. Methods: A total of 240 participants (120 gastric cancer patients and 120 healthy individuals) were included in this study. Data were collecting using a structured questionnaire consisting of 56 questions covering 5 categories. Serum Helicobacter pylori IgG (H. pylori IgG), pepsinogen I (PGI), and pepsinogen II (PGII) were tested in one third of all the participants (40 gastric cancer patients and 40 controls). PGI, PGII, and H. pylori IgG levels were measured using GastroPanel enzyme-linked immunosorbent assay kit (Biohit, Helsinki, Finland). Results: Habits of having leftover meals (OR 2.22, 95%CI 1.27-3.86, p<0.01), daily consumption of tea with salt (OR 1.97, 95%CI 1.18-3.30, p<0.01), smoking on an empty stomach (OR 2.44, 95%CI 1.11-5.37, p<0.05), daily consumption of vegetables (OR 0.45, 95%CI 0.27-0.76, p<0.01), and daily consumption of fruit juice (OR 0.36, 95%CI 0.15-0.85, p<0.05), family history of gastric cancer (parents OR 2.88, 95%CI 1.07-7.78, p<0.05, siblings (OR 3.09, 95%CI 1.09-8.81, p<0.05), and history of gastric diseases (OR 3.65, 95%CI 2.10-6.35, p<0.0001) were identified as protective factors. A low PGI level (<35.25ng/ml) and low PGI/II ratio (<4) were associated with gastric cancer risk. According to ABC(D) method, groups C and D had higher proportion of gastric cancer cases than group A and B (group C, OR 7.50, 95%CI 1.20-47.05, p<0.05; group D, OR 8.3, 95%CI 1.33-51.26, p<0.05). Conclusion: Our findings suggested that gastric cancer risk was more closely related to eating habits, smoking, family history, and precancerous lesions. ABC(D) method seems to be a plausible alternative or supplementary method for stratifying patients at high risk of gastric cancer in this country.

Objective: This study aimed to examine self-efficacy to obtain the HPV vaccination among adolescent girls in Indonesia. Furthermore, factors affecting HPV vaccination self-efficacy was investigated. Methods: A cross-sectional study was conducted 337 among adolescent girls in junior high school (aged 12-15 years). Participants were recruited from four junior high schools in Yogyakarta using consecutive sampling. A self-administered questionnaire requested demographic information, knowledge of HPV and HPV vaccine and self-efficacy to obtain HPV vaccine. School teachers facilitate the data collection adolescent girls using the listed questionnaires. Data analysis used Pearson correlation, chi-squared tests and logistic regression analysis. Results: As many as 50.1% of the adolescent girls reported high self-efficacy to obtain HPV vaccine and 57.9% reported high knowledge about HPV and HPV vaccine. There were significant correlations between self-efficacy and age, vaccination experience, recommendation from health care providers, parental support, social persuasion and anxiety. Parental support contributed to almost 18 times (95% CI:3.837 - 83.648; p<0.0001) while social persuasion was nearly 9 times (95% CI: 3.875-20.011; p<0.0001) more likely to predict the self-efficacy to obtain HPV vaccination. Conclusion: Parental support and social persuasion significantly predict self-efficacy to obtain HPV vaccination. Parental support is the main factor in the decision making of adolescent to obtain HPV vaccination.

Introduction: In the internet era we live in, it is very easy to access information. While this situation has positive effects for patients using the internet, it also brings some negative effects. The effects of the quality of YouTube™ videos on nasopharyngeal cancer were examined. Methods: “Nasopharyngeal Cancer” as search term was used to conduct a search on YouTube™. The ‘Sort by’ search filter was set at ‘relevance’, which is the default for YouTube™ searches. The first 250 results were reviewed and analyzed. After the videos were eliminated according to the exclusion criteria, 45 videos were evaluated by two authors. Video materials were categorized according to “video type” and “source of content”. According to “video type” and “source of content” the videos were categorized into two as educational and testimonial and three as medical institution, medical website, and individual users. After recording the features of all evaluated videos, accuracy score, audiovisual score, modified discern score, patient education materials assessment tool for audiovisual materials (PEMAT) score and usefulness score were determined for each video to evaluate the accuracy, reliability, and understandability of the videos. Results: The usefulness score, modified discern score, and accuracy score of the educational videos were significantly higher than testimonial videos (p<0.001 for all). Educational videos provided more useful and accurate video content than testimonial videos. In addition, it was also determined that the median PEMAT actionability score and audiovisual score of the individual group were statistically significantly lower than medical institutions and medical websites (p=0.001 and p<0.001, respectively). The videos provided by medical institutions, including universities, did not have a significant advantage over other groups in terms of accuracy, reliability, and usefulness. Conclusion: Healthcare videos concerning nasopharyngeal cancer on YouTube™ are heterogeneous and are not peer reviewed. Therefore, medical professions on nasopharyngeal cancer need to upload more accurate, reliable and easy to understand videos onto online platforms such as YouTube™.

Background: Breast cancer prevention still needs to be improved. Calorie restriction is thought to prevent breast cancer through the induction of autophagy. Maranta arundinacea L. (MA) has the potential for calorie restriction because it contains high fiber. This research aimed to observe the effect of dietary MA against dimethylbenz(a)anthracene (DMBA)-induced mammary cancer in Sprague Dawley rats related to autophagy. Methods: Twenty-five Sprague Dawley rats were randomly divided into five groups: 1) control group without DMBA-induced with a standard diet, 2) 20 mg/kg BW of DMBA two times a week for five weeks with a standard diet, 3) DMBA and diet modification with 30% of MA, 4) DMBA and diet modification with 45% of MA, and 5) DMBA and diet modification with 60% of MA. Examination of the nodule was conducted once every week for 22 weeks. Breast tissue/tumor examination underwent histology examination with hematoxylin-eosin. Examinations of immunohistochemical staining against Beclin1, LC3B, and SQSTM1 were conducted to reveal autophagy. The difference of autophagy protein expression was analyzed using One way ANOVA with 95% confidence level and significance set as p<0.05. Results: Cancer was detected in four rats of DMBA standard diet, two rats of 30% MA, one rat of 45% MA. No cancer was detected in the rats of control and rats with 60% of MA group. The Beclin1 expressions showed that the 60% of MA group had the highest score (2.5±0.52) followed by the 45% of MA group (1.87±0.49), control group (1.77±0.11), 30% of MA group (1.28±0.75), and DMBA with standard diet had the lowest score (1.28±0.91). The difference of Beclin1 expressions was statistically significant (p-value=0.03). However, the difference of the LC3B expressions (p-value=0.11) and SQSTM1 expressions (p-value=0.225) were not statistically significant. Conclusion: Dietary modifications with MA potentially prevent breast cancer and induce initiation of autophagy.

Objective: The aim of this study was to improve the direct results of reconstructive surgery in patients operated on for complicated forms of colorectal cancer, by using 5-fluorouracil in the postoperative period. Methods: The study involved 126 patients (they were divided into 2 groups) with colorectal cancer, who underwent reconstructive surgery. They underwent a standard clinical examination and a mandatory examination program. Results: The use of 5-fluorouracil in adjuvant treatment in patients with colorectal cancer significantly reduces the number of subjective clinical manifestations (positional tests) in the main group – 17%, and in the control group – 54.3%, as well as objective clinical manifestations (instrumental research methods) in Group I – 13%, and Group II – 89.5%, respectively. The study shows that in re-operated patients with colorectal cancer who received 5-fluorouracil, abdominal adhesions are characterized by a low content of collagen and fibroblasts, low vascularization and a high content of polymerized fibrin strands. It was also found that re-operated patients with colorectal cancer who did not receive 5-fluorouracil, abdominal adhesions are characterized by a high collagen content, a large number of fibroblasts, and severe angiogenesis. Conclusion: It was found that the prolonged administration of 5-fluorouracil statistically significantly reduces the risk of adhesions, thereby showing the effectiveness of preventing adhesive disease of the abdominal organs. It was shown that the prolonged administration of 5-fluorouracil significantly reduces the number of subjective and objective signs of adhesive disease of the abdominal organs, as well as significantly decreases intraoperative and postoperative complications, the duration of the operation, and the amount of blood loss. In the postoperative period, it reduces the length of hospital stay and improves the quality of life of patients.
