Abstract
Background Assessment of cancer patients' relatives' knowledge, perception, and attitude regarding cancer. To spread awareness about oral cancer in areas with a high prevalence of cancer, aid in its prevention, and accelerate the treatment to facilitate early-stage disease elimination and improve prognosis. Material and methods A cross-sectional study conducted at a hospital was done, where 23 questions were posed to the relatives of the patients admitted to the hospital. The questions were formulated to assess the knowledge of relatives regarding cancer, their perception, and their attitude toward the decision-making and treatment protocols. The questions also included information about the patient's habits and associated problems with it. A total of 400 relatives participated in the study, where all participants were adequately informed beforehand, and their written consent was taken before proceeding with the questions. All the questions were formulated in the native language that they could easily understand. Result The study found that participants had limited knowledge about the causes, treatment, prevention, and recurrence of oral cancer. Additionally, the family members were unsupportive of therapy and delayed seeking medical care. Conclusion It is crucial to raise awareness about oral cancer and inform individuals about available treatments, government programs, and counseling services to aid them in decision-making.

Immunotherapy for Urological Tumors on YouTube TM: An Information-Quality Analysis. Vaccines (Basel) 2022; 11:vaccines11010092. [PMID: 36679937 PMCID: PMC9866846 DOI: 10.3390/vaccines11010092] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/22/2022] [Accepted: 12/28/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND YouTubeTM is an open-access source for mass information. Several previous studies of YouTubeTM videos showed a high rate of misinformation in the urological field. The aim of the current study was to evaluate the quality of information on immunotherapy (IMT) for urological tumors uploaded to YouTubeTM. METHODS YouTubeTM videos were searched using nine keyword combinations. The PEMAT, the DISCERN tool, and the Misinformation scale were used to assess the quality of information in YouTubeTM videos about IMT for urological tumors. Descriptive statistics and Kruskal-Wallis, Chi-square, proportion, and Pearson's tests were performed. RESULTS According to the selection criteria, 156 YouTubeTM videos were suitable for the analysis and stratified according to topic (urothelial carcinoma vs. renal cell cancer vs. prostate cancer vs. general information on IMT). According to PEMAT A/V, the overall Understandability score was 40% (Inter-Quartile Range [IQR]: 20-61.5) and the overall Actionability score was 0% (IQR: 0-25). According to the DISCERN tool, the overall DISCERN score was 44 (IQR: 39-53.2), defined as "fair". According to the Misinformation scale, we recorded the lowest median overall score for item 4 ("IMT in multimodality approach") and item 5 ("Future perspective"). CONCLUSIONS YouTubeTM cannot be recommended as a reliable source of information on IMT for urological malignancies. In addition, YouTubeTM videos contributed to the spread of misinformation by underestimating the role of IMT in a multimodality approach and missing the findings of published clinical trial results.

Abstract
Background Colorectal cancer (CRC) is a major contributor to morbidity and mortality related to cancer. Only ~5% of all CRCs occur as a result of pathogenic variants in well‐defined CRC predisposing genes. The frequency and effect of exonuclease domain pathogenic variants of POLE and POLD1 genes in Middle Eastern CRCs is still unknown. Methods Targeted capture sequencing and Sanger sequencing technologies were employed to investigate the germline exonuclease domain pathogenic variants of POLE and POLD1 in Middle Eastern CRCs. Immunohistochemical analysis of POLE and POLD1 was performed to look for associations between protein expression and clinico‐pathological characteristics. Results Five damaging or possibly damaging variants (0.44%) were detected in 1,135 CRC cases, four in POLE gene (0.35%, 4/1,135) and one (0.1%, 1/1,135) in POLD1 gene. Furthermore, low POLE protein expression was identified in 38.9% (417/1071) cases and a significant association with lymph node involvement (p = .0184) and grade 3 tumors (p = .0139) was observed. Whereas, low POLD1 expression was observed in 51.9% (555/1069) of cases and was significantly associated with adenocarcinoma histology (p = .0164), larger tumor size (T3 and T4 tumors; p = .0012), and stage III tumors (p = .0341). Conclusion POLE and POLD1 exonuclease domain pathogenic variants frequency in CRC cases was very low and these exonuclease domain pathogenic variants might be rare causative events of CRC in the Middle East. POLE and POLD1 can be included in multi‐gene panels to screen CRC patients.

Abstract
Cancer is responsible for substantial burden on communities and more specifically on less developed countries. The incidence of cancer is on the rise due to population growth and aging, also due to increment of the risk factors such as smoking, increasing weight, low physical activity associated with adoption of western lifestyle. Around 14 million cases of new cancer and 8 million deaths from cancer is estimated to occur by 2012. This cross-sectional study was conducted in Baghdad from June 2016 to October 2016. Participants were selected according to our inclusion criteria, namely aged between 18 to 40 years and not being diagnosed with any chronic diseases. Those who fulfilled the inclusion criteria were 700 participants who completed the questionnaire. Results showed that most of our participants had low perceived susceptibility to cancer risk (62.4%), low perceived severity (59.8%), but good perceived benefits of screening (56.6%). Hierarchal linear regression analysis showed that sociodemographic factors of gender, marital status, and education level were statistically significant. Moreover, factors of health behaviour such as practice towards health and preventive behaviour were associated with the outcome. Finally, treatment control and emotional factors were mostly predicting the outcome. Perceived susceptibility to cancer along with its psychological factors and behaviour were important contributors to self-perceived health in this study. Hence there is association between perception and future morbidity and mortality, thus it is crucial for public health policy. Comprehensive health programs that include health promotion campaigns and proper health care services that deals with secondary prevention.

Medical specialty visits and diagnoses received by Saudi patients prior to a diagnosis of narcolepsy. Sleep Breath 2019; 23:603-609. [PMID: 30820852 DOI: 10.1007/s11325-019-01807-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 02/09/2019] [Accepted: 02/14/2019] [Indexed: 01/07/2023]
Abstract
PURPOSE Narcolepsy is an uncommon neurological disorder characterized by excessive daytime sleepiness (EDS) and multiple other symptoms. Due to the under-recognition of narcolepsy symptoms, patients are often misdiagnosed. This study aimed to assess the types of specialties visited and the diagnoses received by Saudi patients prior to their narcolepsy diagnosis. METHODS The study included 55 consecutive patients with type-1 and type-2 narcolepsy who attended the narcolepsy clinic between August 2017 and December 2017. Narcolepsy was diagnosed according to the International Classification of Sleep Disorders-third edition criteria. We evaluated sociodemographic data, the specialties visited, and diagnoses and treatments received prior to visiting a sleep specialist. RESULTS The mean diagnostic delay was 9.1 ± 8.4 years (1-43 years). Multiple linear regression analysis identified early onset as the only predictor of a delayed diagnosis (β coefficient = - 0.262, p = 0.03). EDS was the main symptom that prompted patients to seek medical consultation, and only one patient had been (1.8%) referred with the diagnosis of narcolepsy. In the study group, 82% of the patients were misdiagnosed with a mental or neurological disorder or were thought to be afflicted by "envy," "evil eye," or "black magic" before receiving a correct diagnosis. No significant differences were detected between patients with narcolepsy type-1 and narcolepsy type-2. CONCLUSIONS Delays in diagnosing narcolepsy remain a major problem for Saudi patients with this disorder. We found that Saudi patients with narcolepsy had visited several medical specialists and faith healers and were misdiagnosed prior to visiting a sleep specialist.

Abstract
This study examined cancer knowledge between church-going younger versus older Chinese adults. Hou's 8-item validated cancer screening knowledge test (CSKT) and a new 14-item cancer warning signs test (CWST) were used to assess objective knowledge. Subjective knowledge was measured by one overall 5-point Likert scale item. A total of 372 Taiwanese and Chinese Americans from nine churches participated. Although there were no significant differences by age on either the CSKT scores (younger = 5.89 vs. older = 5.71; p = .297) or the CWST (younger = 6.27 vs. older = 5.86; p = .245), subjective knowledge was higher among older Chinese adults (younger = 2.44 vs. older = 3.05, p < .001). Older Chinese adults were also more likely to identify cancer warning signs correctly, while younger adults were more likely to identify false warning signs correctly. Results have implication on tailoring cancer knowledge type (subjective vs. objective) and content domain (screening vs. warning signs). Findings can help health educators better understand cancer education needs among Chinese adults.

Abstract
BACKGROUND Because of the significant incidence and mortality of cancer in Iran, a Comprehensive National Cancer Control Program for the prevention and early detection of cancer was launched in 2007. However, cancer awareness and screening rates in Iran did not improve. This study aimed to evaluate public attitudes toward cancer and cancer patients in Iran. MATERIALS AND METHODS We conducted a cross-sectional survey among 953 non-institutionalized individuals in Isfahan, Iran, from November 2014 to February 2015. We collected data on attitudes toward cancer in three domains (impossibility of recovery, cancer stereotypes, and discrimination), as well as questions on willingness to disclose a cancer diagnosis. RESULTS Among all participants, 33.9% agreed that it is very difficult to regain one's health after a cancer diagnosis, 17.4% felt uncomfortable with a cancer patient, and 26.9% said that they would avoid marrying people whose family members had cancer. While 88.9% of study participants said that cancer patients deserve to be protected in society, 53.3% and 48.4% of participants agreed that they would not disclose a cancer diagnosis to neighbors and coworkers, respectively. CONCLUSION Negative attitudes with respect to impossibility of recovery and discrimination toward cancer and cancer patients were common among urban Iranians. Most people would not disclose a cancer diagnosis to others in spite of advancements in cancer diagnosis and treatment, reflecting unfavorable attitudes toward cancer and cancer patients in society. Successful implementation of cancer awareness and prevention programs in Iran may require social changes based on adequate information on cancer and cancer patients. IMPLICATIONS FOR PRACTICE Public attitudes toward cancer and cancer patients are an important factor affecting cancer control programs as well as quality of life and recovery of cancer patients. The issue has not been studied in Iran and the surrounding countries in the Middle East. This is the first report presented on the subject. These findings can be used by health policy makers, health managers, and clinicians for better practice.

Identification of novel BRCA founder mutations in Middle Eastern breast cancer patients using capture and Sanger sequencing analysis. Int J Cancer 2016; 139:1091-7. [PMID: 27082205 PMCID: PMC5111783 DOI: 10.1002/ijc.30143] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2016] [Revised: 03/29/2016] [Accepted: 04/07/2016] [Indexed: 12/17/2022]
Abstract
Ethnic differences of breast cancer genomics have prompted us to investigate the spectra of BRCA1 and BRCA2 mutations in different populations. The prevalence and effect of BRCA 1 and BRCA 2 mutations in Middle Eastern population is not fully explored. To characterize the prevalence of BRCA mutations in Middle Eastern breast cancer patients, BRCA mutation screening was performed in 818 unselected breast cancer patients using Capture and/or Sanger sequencing. 19 short tandem repeat (STR) markers were used for founder mutation analysis. In our study, nine different types of deleterious mutation were identified in 28 (3.4%) cases, 25 (89.3%) cases in BRCA 1 and 3 (10.7%) cases in BRCA 2. Seven recurrent mutations identified accounted for 92.9% (26/28) of all the mutant cases. Haplotype analysis was performed to confirm c.1140 dupG and c.4136_4137delCT mutations as novel putative founder mutation, accounting for 46.4% (13/28) of all BRCA mutant cases and 1.6% (13/818) of all the breast cancer cases, respectively. Moreover, BRCA 1 mutation was significantly associated with BRCA 1 protein expression loss (p = 0.0005). Our finding revealed that a substantial number of BRCA mutations were identified in clinically high risk breast cancer from Middle East region. Identification of the mutation spectrum, prevalence and founder effect in Middle Eastern population facilitates genetic counseling, risk assessment and development of cost‐effective screening strategy. What's new? Genetic testing for BRCA mutations reveals the ethnic diversity of prevalence and spectrum of BRCA1/BRCA2 mutations in breast cancer. Compared with other populations, however, little is known about ethnic differences in breast cancer genomics in populations in the Middle East region. Here, BRCA mutation screening was carried out in 818 Middle Eastern breast cancer patients. The authors identify two putative founder mutations—together accounting for more than 46% of BRCA cases—and a particular spectrum of deleterious BRCA mutations, which may be unique to the population. The findings could impact genetic counseling in Middle Eastern populations.
