Early-Onset Colorectal Cancer in Egypt: Pathological Characters, Patterns of Care, and Survival Compared to Average-Age Onset Colorectal Cancer: A Retrospective Multicenter Study.

PURPOSE: Early-onset colorectal cancer (EOCRC) is a rising health problem. The incidence of EOCRC has increased over the past 2 decades all over the world. Reports from Egypt since the 1990s have reported a higher incidence among young populations with no identifiable risk factors. The aim of this study was to assess EOCRC in Egypt regarding incidence, characteristics, treatment pattern, and survival compared with average age onset and elderly patients. MATERIALS AND METHODS: This was a retrospective, record-based, cohort study combining data from four different cancer centers in Egypt. We grouped patients according to age into three categories: the EOCRC group for patients age ≤45 years and the average age onset and elderly cancer group (for patients age ≥65 years). RESULTS: The study included 1,310 patients with histopathologically proven colorectal cancer, representing four different geographical areas in Egypt. Patients with EOCRC represented 42.4% of the study population. Female patients were 50.6% among the EOCRC group and 52.5% among the average age group. Rectal tumors were significantly higher in EOCRC (54.7% v 40.6%; P < .001). There was no significant difference between both groups regarding the tumor stage at presentation, obstruction, or presence of metastases at presentation. Patients with EOCRC had a significantly higher rate of peritoneum/adnexa metastases than the average age ones (12.3% in EOCRC v 6.9% in the average age group; P < .001). No statistically significant differences between EOCRC and average age groups in both disease-free survival and overall survival were reported. CONCLUSION: A comprehensive framework for the study of EOCRC is required in Egypt as well as a genomic analysis to identify possible underlying genetic alterations responsible for the high incidence of EOCRC.

Plastic use for food and drinks and related knowledge, attitudes, and practices among a sample of Egyptians.

Introduction: Plastic is extensively used in everyday life, particularly for food and beverage containers. The inappropriate use of these containers may lead to the leaching of various chemicals from plastic, such as bisphenol A, phthalate, and styrene, which cause numerous adverse health effects. This study aimed to assess the knowledge, attitudes, and practices toward using plastic for food and drinks among a sample of the Egyptian population. Materials and methods: A questionnaire was designed based on scientific literature to assess sociodemographic data, knowledge, attitudes, and practices toward the use of plastic for food and drinks. A total of 639 participants were recruited by employing the convenience sampling technique. Results: More than half of the participants (347, 54%) had poor knowledge scores. Personal experiences, social media, and web pages represented the most common knowledge sources. A comparison between plastic-related knowledge scores and the studied sociodemographic characteristics revealed statistically significant differences in age, gender, education, marital status, residence, working, and socioeconomic standard. A good attitude was reported by the majority (515, 80.6%) of participants. The majority (493, 77.2%) were occasional and frequent plastic users and the practice scores were significantly associated with age, education, residence, and socioeconomic standard. Higher educational level, gender (women), and rural residence were predictors of good participants knowledge, while lower socioeconomic status and urban residence were predictors of bad participants practice in a multivariate logistic regression analysis. Conclusion: The observed unsatisfactory knowledge and practice scores vs. the high attitude indicates a knowledge gap that can help direct future improvements. We call for public awareness programs about safe plastic use and the related health hazards of plastic chemicals. We also stress upon the urgent need for a collaboration between health authorities and the plastic and food industry to guarantee that information about proper plastic use is conveyed to consumers.

Management of Incidental Uncontrolled Elevation of Intraoperative Blood Pressure: A Comparative Study on Nitroglycerine Versus Dexmedetomidine Infusion.

Background: Uncontrolled elevation of intraoperative blood pressure can result in deleterious effects with increased risk of morbidity and mortality. Objectives: We aimed to compare nitroglycerine infusion with dexmedetomidine infusion in controlling accidental intraoperative uncontrolled hypertension. Methods: This comparative study was conducted on 73 hypertensive patients undergoing cancer surgeries who experienced uncontrolled intraoperative hypertension. The data of 38 patients were retrieved from the medical records for the nitroglycerine group and 35 patients were prospectively enrolled for the dexmedetomidine group. Group N received nitroglycerine infusion (0.3 - 1 µg/kg/min), while group D received dexmedetomidine infusion (0.2 - 0.7 µg/kg/h). Results: Both groups were comparable regarding their demographic data and clinical characteristics. Systolic, diastolic, and mean arterial pressure (MAP) values were significantly lower in group N compared to group D during the period between 60 and 120 minutes intraoperatively (P < 0.001). Heart rate values were significantly lower in group D than in group N (P < 0.001). Postoperative sedation scores were better for group D with lower analgesic requirements (P < 0.001). Conclusions: Dexmedetomidine infusion can be used to manage the uncontrolled intraoperative elevation of blood pressure in selected patient population.

Prevalence, characteristics, and factors associated with caffeine-withdrawal headache during the first day of Ramadan.

BACKGROUND: Data regarding prevalence, characteristics, and factors associated with caffeine-withdrawal headache are lacking. This work aimed to study the prevalence of caffeine-withdrawal headache among caffeine consumers during Ramadan's first day and describe its characteristics and associated factors. METHODS: This analytical cross-sectional study targeted 755 caffeine consumers eligible to fast on the first day of Ramadan. Two methodological approaches were followed: an online open survey and a face-to-face interview. Using an adjusted form of food frequency questionnaire, eligible participants were requested to report their intake of caffeine-containing products during the last week of Shaaban month, the month preceding Ramadan. RESULTS: The prevalence of caffeine-withdrawal headache on the first day of Ramadan was 419 (55.5%), with 95% confidence interval (CI; 51.9-59.0%). The headache in the majority of the participants was throbbing in character (249/419, 59.4%), diffuse (146/419, 34.8%), and moderate in intensity (227/419, 54.2%). Participants who developed caffeine-withdrawal headache had significantly higher body mass index (27.2 ± 5.1 vs. 26.3 ± 5 [mean ± standard deviation], p-value = 0.012), daily caffeine intake, mg (316 [185.2-537.8] vs. 144.4 [60.0-312.4] [median interquartile range (IQR)], p-value < 0.001), and caffeine intake mg/kg body weight (4.7 [2.6-7.2] vs. 1.9 [0.8-4.4] [median (IQR)], p-value < 0.001) than participants who did not develop it. Mild, moderate, and severe caffeine use disorder were found to have adjusted associations with developing caffeine-withdrawal headache. They increased the odds of headache by 5.3 (95% CI = 3.40-8.3), 10.2 (95% CI = 5.9-17.5), and 15.5 (95% CI = 9.0-26.8) times, respectively. The optimal cut-off value of daily caffeine intake/Kg body weight was determined at 1.97 mg/kg with an area under the curve of 0.722 and sensitivity and specificity of 85.1% and 50.2%, respectively. CONCLUSION: Daily caffeine intake/kg body weight and caffeine use disorder are significantly associated with a caffeine-withdrawal headache.

Efficacy and safety of combined fractional ablative CO2 laser and 5 fluorouracil in the treatment of acral vitiligo: An open, uncontrolled study.

BACKGROUND: Acral lesions of vitiligo are most likely recalcitrant to the known lines of treatment. Ablative fractional CO2 has shown efficacy in treatment of vitiligo in combination with other modalities. METHODS: Thirty non-segmental vitiligo patients with acral lesion were included in the study. Each patient was subjected to fractional Carbon Dioxide Laser Treatment followed by application of 5 fluorouracil (5FU) cream for five consecutive days. Evaluation was done 3 weeks from the start of treatment and 12 weeks after the last treatment session using VESTA score, evaluation of patients' photos by blinded investigation in addition to patients' satisfaction scores. RESULTS: Patients showed significant improvement of Vitiligo extent score for a target area (VESTA) score and developed considerable degree of repigmentation as assessed by blinded investigators. CONCLUSION: The combination of fractional ablative CO2 and 5FU is an effective and safe procedure for the treatment of acral vitiligo with promising results offering patients a new therapeutic window.

Downregulation of interleukin 36γ and its cleaver cathepsin G following treatment with narrow-band ultraviolet B phototherapy in psoriasis vulgaris.

BACKGROUND: Growing evidence suggests the important role of IL-36 in the pathogenesis of psoriasis. Cathepsin G is a neutrophil-derived protease that can activate IL-36γ. OBJECTIVE: To assess the expression of IL-36γ and cathepsin G in psoriasis and to quantify the impact of treatment with narrow-band ultraviolet B phototherapy (NB-UVB) on their levels. METHODS: This case-control study involved 26 patients with moderate-severe psoriasis and 25 healthy volunteers. Psoriasis patients eligible for phototherapy received 24 NB-UVB sessions. Punch skin biopsies were obtained from all participants at recruitment and after phototherapy from patients. Real-time PCR was utilized for quantitative assessment of IL-36γ and cathepsin G expression in tissue samples. RESULTS: The expression of IL-36γ and cathepsin G was significantly higher in psoriasis before NB-UVB therapy compared to controls (p < .001). Both proteins decreased significantly with clinical improvement following NB-UVB therapy compared to baseline (p < .001). However, their expression after treatment was still higher than controls (p < .001). CONCLUSION: IL-36γ and cathepsin G expression is upregulated in psoriatic lesions, supporting their role as mediators of inflammation in psoriasis. Downregulation of IL-36γ and cathepsin G is a possible mechanism for psoriasis improvement after NB-UVB therapy. IL-36 and cathepsin G can be considered as therapeutic targets for psoriasis.

Violence and sociodemographic related factors among a sample of Egyptian women during the COVID-19 pandemic.

BACKGROUND: Violence against women is a worldwide problem that affects different social and economic classes, and this violence has almost increased with pandemics as the COVID-19 pandemic. The present survey aimed to assess the prevalence of violence against women in Egypt during the COVID-19 pandemic and to identify the relationship between sociodemographic factors and violence exposure. A total of 509 women were recruited using a self-completion e-form questionnaire. RESULTS: The prevalence of violence experienced by women was (43.8%); the most common type was the emotional representing (96.0%) of exposed women, while sexual violence was the least common (13.5%). Violence exposure was affected significantly by residence governorates, husbands' working status, reduced husbands' working hours, and history of violence exposure. CONCLUSIONS: Violence against women in Egypt was increased during the COVID-19 pandemic, which raises the need for a strong and urgent anti-violence program to control this problem.

JAK1 rs310241 and JAK3 rs3008 Genotypes May Increase Susceptibility to Psoriasis: A Case Control Study.

BACKGROUND: Janus kinases (JAKs) are a family of non-receptor protein tyrosine kinases that are expressed in a variety of tissues. Several JAK-controlled cytokine receptor pathways are incriminated in the initiation and progression of psoriasis. Genetic polymorphisms influencing JAK expression would be anticipated to have a great impact on disease activity. OBJECTIVE: The aim of the study was to evaluate the association between JAK1 rs310241 and JAK3 rs3008 polymorphisms and the risk of developing psoriasis. METHODS: Blood samples of 150 patients and 120 controls were screened for nucleotide polymorphisms in JAK1 rs310241 and JAK3 rs3008 genes by using polymerase chain reaction (PCR)-restriction fragment length polymorphism technique. RESULTS: The GG genotype of the JAK1 rs310241 and JAK3 rs3008 genes was significantly associated with an increase in psoriasis risk (p = 0.000, OR = 7.7, 95% CI = 2.8-21.5; p = 0.003, OR = 3.3, 95% CI = 1.5-6.9, respectively). The G allele of both genes was also associated with psoriasis susceptibility (p = 0.000, OR = 2.0, 95% CI = 1.4-2.8; p = 0.002, OR = 1.7, 95% CI = 1.2-2.4, respectively). CONCLUSION: The results indicate a possible association between JAK1 rs310241 and JAK3 rs3008 gene polymorphisms and susceptibility to psoriasis. These findings validate the importance of these molecules in psoriasis and may enable the identification of the individuals most susceptible to the disease.

Capecitabine-Based Chemoendocrine Combination as First-Line Treatment for Metastatic Hormone-Positive Metastatic Breast Cancer: Phase 2 Study.

BACKGROUND: Preclinical studies have suggested a synergistic effect of tamoxifen and capecitabine in estrogen receptor-positive cell lines. We evaluated the safety and efficacy of first-line chemoendocrine treatment in patients with metastatic breast cancer. Biochemical assessment was performed of serum levels of thymidine phosphorylase enzyme (TP), serum tamoxifen, hydroxytamoxifen, and 5-fluorouracil in relationship to efficacy. PATIENTS AND METHODS: This prospective phase 2 interventional study studied patients with estrogen receptor-positive, HER2- metastatic breast cancer who received either tamoxifen/capecitabine or letrozole/capecitabine as first-line treatment. The dose of capecitabine provided at 2000 mg per day continuously as a fixed dose. RESULTS: Forty women with a median age of 49.3 years were enrolled. For the whole study group, median progression-free survival (PFS) was 10 months and median overall survival (OS) was 23.3 months. The overall response rate was 60% and the clinical benefit rate 82.5%. Progesterone receptor positivity was associated with significantly longer PFS (12 vs. 7 months, P = .021). The most frequent adverse events were palmar-plantar erythrodysesthesia (62.5%), fatigue (62.5%), diarrhea (30%), abdominal pain (12.5%), and constipation (10%). Changes in serum level of TP were not correlated to response to treatment, PFS, or OS. Higher serum levels of tamoxifen and hydroxytamoxifen were correlated with higher response rates and longer PFS but not OS. CONCLUSION: Chemoendocrine treatment is well tolerated, with no evidence of contradictory effects between the combination components. However, the efficacy data need more validation.

Clinical and epidemiologic features of psoriasis patients in an Egyptian medical center.

BACKGROUND: Identification of epidemiologic and phenotypic variations of psoriasis among different ethnic groups can further our understanding of this perplexing disease, aiming at better management of patients worldwide. OBJECTIVE: To provide a descriptive analysis of psoriasis patients registered at Kasr Al-Ainy Psoriasis Unit Disease Registry. METHODS: This retrospective single-center registry study included patient records between November 2015 and November 2018 (2534 patients). Sociodemographic and phenotypic data were analyzed. RESULTS: The mean age of the registered patients was 39.3 years and 56.3% were men. Stress was the main precipitating factor (48.3%), whereas the most common symptom reported was itching (82.4%). The median body mass index was 27.5, and the median percentage of body surface area involved was 10.0. The mean Psoriasis Area Severity Index score was 8.7, and the mean Psoriasis Disability Index score was 13.0. Both parameters correlated positively, and both showed significantly higher means in smokers. LIMITATIONS: Despite that the study was performed at a highly specialized tertiary care center with a high flow of patients, this was still a single-center registry. CONCLUSIONS: This work shows that the characteristics of Egyptian patients with psoriasis are comparable to those of other studied ethnic groups, with minor differences.

Circulating miR-26a, miR-106b, miR-107 and miR-133b stratify hepatocellular carcinoma patients according to their response to transarterial chemoembolization.

BACKGROUND: A number of hepatocellular carcinoma (HCC) patients have developed resistance against transcatheter arterial chemoembolization (TACE) treatment. In this study, we aimed to develop a panel of microRNAs (miRs) biomarkers to predict clinical outcomes in HCC patients after TACE treatment. METHODS: The expression level of twenty miRs was evaluated in FFPE tissues collected from 33 HCC patients. We selected four differentially expressed miRs in TACE-responders versus non-responders and re-assessed their expression in 51 serum samples. The expressions of miRs associated with overall survival (OS), progression-free survival (PFS), and treatment outcomes were investigated. The diagnostic accuracy of these miRs in predicting patients' response to TACE was also evaluated. RESULTS: The baseline of miR-106b, miR-107 and miR-133b was significantly elevated (p < .001) in sera of TACE-responders while miR-26a was elevated (p < .001) in non-responders. miR-26a and miR-133b recorded the highest diagnostic performance as individual classifiers in response to TACE (AUC = 1.0 and 100% sensitivity and specificity). Intriguingly, miR-133b distinguished complete responders from partial responders and non-responders (AUC ≥ 0.90). The PFS was improved (p < .05) in the high expression group of miR-31, miR-200b, miR-133b and miR-181a over their low expression group. CONCLUSION: Circulating miR-133b, miR-26a, miR-107 and miR-106 in serum are potential candidates to be utilized as prognostic biomarkers for predication of TACE treatment outcomes in HCC patients.

Impact of Global DNA Methylation in Treatment Outcome of Colorectal Cancer Patients.

Background: Global DNA methylation has an impact in cancer pathogenesis and progression. This study aimed at investigating the impact of global DNA methylation in treatment outcome of Colorectal Cancer (CRC). Patients and Methods: Global DNA methylation was measured by LC/MS/MS in peripheral blood leucocytes of 102, 48, and 32 Egyptian CRC patients at baseline and after 3 and 6 months of Fluoropyrimidine (FP) therapy respectively, in addition to 32 normal healthy matched in age and sex. The genetic expressions of DNA methyl transferases (DNMTs) were determined and correlated with patients' survival using univariate and multivariate methods of analyses. Results: Egyptian CRC patients had significant global hypomethylation of 5mC level and 5mC % with overexpression of DNMT3A and DNMT3B. Significant higher 5mC levels were shown in patients > 45 years, male gender, T2 tumors, stage II, negative lymph nodes, and absence of metastasis. FP therapy significantly reduced DNA methylation particularly in the subgroups of patients with high DNA methylation level at baseline and good prognostic features. After 3 years of follow up, patients with 5mC % > 8.02% had significant poor overall survival (OS) while, significant better event-free survival (EFS) was found in patients with 5mC level > 0.55. High initial CEA level and presence of metastasis were significantly associated with hazards of disease progression and death. Conclusion: Global DNA methylation has a significant impact on the treatment outcome and survival of Egyptian CRC patients treated with FP- based therapy.

Psychiatric disorders among a sample of internally displaced persons in South Darfur.

BACKGROUND: The violent armed conflict in Darfur has been ongoing for years getting the attention of human rights activists and mental health professionals. AIM: The aim of this study was to assess psychiatric disorders in a sample of internally displaced persons (IDPs) in South Darfur. METHOD: A cross-sectional observational study, as a part of the 'Darfur Campaign' organized by Arab Federation of Psychiatrists, assessing psychiatric disorders in a sample of internally displaced women using the Structured Clinical Interview for DSM-IV (SCID-I) (clinical version). RESULTS: Up to 25.7% of participants had lost a close family member or more in the violent clashes. Psychiatric diagnoses were found in 62.2% of the participants. The most frequently reported was post-traumatic stress disorder (PTSD) reaching 14.9%, followed by depression 13.5% (among which 2.7% with psychotic features), while comorbid PTSD and depression reached 8.1% of participants. Patients with psychiatric diagnoses had an older age (36.6 years) (p = .024). Suffering from a psychiatric disorder was found to be associated with losing a family member in the conflict (p = .015), being 35.6% in patients with psychiatric diagnoses compared to 10.3% in those without losing a family member in the conflict (odds ratio (OR) = .7, 95% confidence interval (CI) = 1.25-18.28). CONCLUSIONS: This study used a standardized tool for diagnosing psychiatric morbidity among refugees in Darfur to give as much as possible an actual description of the problems and psychiatric morbidity caused by human-made disasters. This study can help to lead to a more detailed and specific mental health service program much needed by this population.

Survival analysis after diagnosis with malignancy of Egyptian adolescent patients: a single-center experience.

BACKGROUND: Adolescents with malignancy represent a unique population in oncology, receiving care in pediatric or adult oncology institutions. Previously, adolescents and young adults (AYAs) had good survival rates; yet in the last few decades, AYAs have shown inferior survival rates compared with children due to the increasingly reported AYA-specific malignancies with poor survival rates. This study evaluates the clinicoepidemiological aspects of adolescent cancer diagnosed in a Pediatric Oncology Unit over a 10-year period, the associated risk factors, and the survival rate. METHODS: Retrospective data analysis of patients aged 10 to 19 years diagnosed in the Pediatric Oncology Unit, Children's Hospital Ain Shams University, Cairo, Egypt, during the period from January 1, 2000 to January 1, 2010. RESULTS: There were 158 patients (20% of total number of patients diagnosed during the same period), 84 male (53.2%) and 74 female (46.8%). Hematological malignancies were the most common (91.8%), with acute lymphoblastic leukemia being the most prevalent malignancy (61.5%), and solid tumors represented 8.2% of the total number of patients. The 5- and 10-year overall survival rates were 45.2% and 40.2%, respectively. The 5- and 10-year event-free survival rates for hematological malignancies were 39.9% and 37.3%, and for solid tumors it was 36.4%. Infection was the main cause of death (50%). CONCLUSIONS: Age-related survival gap exists for adolescent cancer patients compared with children. Further studies are needed to provide evidence about optimal treatment regimens in this age group.
