Objectives This study aims to explore effects of osteoprotegerin (OPG) gene polymorphisms and other possible factors on bone mineral density (BMD) in children with systemic lupus erythematosus (SLE). Methods Osteoprotegerin gene rs2073617 and rs3134069 were evaluated in 74 SLE patients and 100 controls then genotypes, alleles and haplotypes’ frequencies were compared between cases and controls and between patients with BMD z-scores above and below −2 evaluated by dual energy X-ray absorptiometry (DEXA). Disease activity was evaluated by SLE disease activity index (SLEDAI). Results The patients aged 14.01 ± 2.6 years and included 57 (77%) females and 27 (36%) patients with BMD z-score below −2. Genotypes, alleles, and haplotypes frequencies did not differ between patients and controls (p>0.05 for all). Rs3134069 GG genotype and G allele (p=0.001, 0.002) and rs2073617 TT genotype and T allele (p=0.01, 0.006) were significantly higher in patients with BMD below −2. Cumulative glucocorticoids dose, disease duration, and SLEDAI scores were higher in patients with BMD below −2 (p=0.01, 0.01, p 0.02, 0.003, and 0.002, respectively). Conclusions This is the first study to demonstrate OPG gene influence on BMD in children with SLE. The studied SNPs are not risk for developing SLE but, rs2073617 T allele is a possible predictor for reduced BMD in SLE. Other predictors include long disease duration and high activity supporting that osteoporosis in SLE is multifactorial.

Background: Eating disorders (EDs) are serious illnesses associated with medical complications and have been increased, especially among societies with an excessive concern about weight, shape, or appearance. This study aimed to investigate the prevalence of EDs among the individuals attending weight management centers and its associated factors. Methods: A cross-sectional study was carried out among individuals attending four weight management centers in Tanta, Gharbia Governorate, Egypt during the period from July to December 2016. Precoded interview questionnaires were used to identify the following data: sociodemographic characteristics and medical history of depression or psychological disorders and the Eating Attitude Test (EAT-40) was used to assess the attitudes, behavior, and traits associated with the EDs. Results: A total of 400 participants (112 males and 288 females) were included in the study. According to EAT-40 questionnaires, the prevalence of positive and negative EDs was 65.0% ( n = 260) and 35.0% ( n = 140), respectively. EDs were more likely reported by females, married singles, rural residents, those with higher education, and nonworking or part-time working patients, those who were overweight or obese, and who were suffering from depression or any psychological problems. Logistic regression analysis revealed that the independent predictors of EDs were age (adjusted odds ratio [ OR ]: 1.06), nonworking (adjusted OR : 2.32) or part-time working (adjusted OR : 2.18), increased body weight (adjusted OR : 2.66 for overweight and adjusted OR : 1.24 for obese), and having a history of depression or any psychological problem (adjusted OR : 2.76). Factor analysis of EAT-40 revealed four factors (eating behavior, diet-related lifestyle, weight concern, and food preoccupation) that were responsible for 33.2% of the total variance. Conclusions: EDs are prevalent among individuals attending the weight management centers in a northern city in Egypt. Specific management strategies are warranted to address this commonly prevalent disease.

Background: Non-adherence with recommended follow-up visits is a major barrier for completing treatment of viral hepatitis and is consequently associated with unfavorable outcomes of health services. Objectives: To estimate the magnitude and identify perceived reasons and patient characteristics associated with loss to follow-up in a tertiary care setting. Methods: A two-step cross-sectional study design was used, including a chart review (2011) followed by phone survey (2012). Loss to follow-up was recorded among those who were diagnosed with hepatitis B (HBV) or C (HCV) during 2009–2010 but never returned for recommended/scheduled follow-up appointment(s). Results: A total of 328 patients (202 HBV and 126 HCV) were included in the current analysis. The average age was 49.6 ± 17.9 years, and 57% were males. Out of 328, 131 (40%) were not advised to do follow-up, and 98 (30%) were not doing follow-up. Perceived reasons for loss to follow-up were as follows: unaware that a follow-up appointment was scheduled (69%), never informed of need for follow-up by healthcare provider (15%), personal belief that follow-up was not necessary (9%), logistical reasons (3%) and other reasons (5%). Loss to follow-up was higher among those who had been diagnosed with HBV, referred by non-liver-related specialty, never advised to follow-up, unaware of their diagnosis, incorrectly identified their type of hepatitis, lacking hepatitis complications, having full medical coverage, pregnant, and those with low knowledge or negative attitude towards hepatitis. Conclusions: Loss to follow-up is a significant problem among patients with hepatitis in a tertiary care center, with several patient and system failures being implicated.

Background Breast cancer in Egypt is the most common cancer among women and is the leading cause of cancer mortality. Traditionally, axillary lymph node involvement is considered among the most important prognostic factors in breast cancer. Nonetheless, accumulating evidence suggests that axillary lymph node ratio should be considered as an alternative to classical pN classification. Materials and methods We performed a retrospective analysis of patients with operable node-positive breast cancer, to investigate the prognostic significance of axillary lymph node ratio. Results Five-hundred patients were considered eligible for the analysis. Median follow-up was 35 months (95% CI 32–37 months), the median disease-free survival (DFS) was 49 months (95% CI, 46.4–52.2 months). The classification of patients based on pN staging system failed to prognosticate DFS in the multivariate analysis. Conversely, grade 3 tumors, and the intermediate (>0.20 to ⩽0.65) and high (>0.65) LNR were the only variables that were independently associated with adverse DFS. The overall survival (OS) in this series was 69 months (95% CI 60–77). Conclusion The analysis of outcome of patients with early breast cancer in Egypt identified the adverse prognostic effects of high tumor grade, ER negativity and intermediate and high LNR on DFS. If the utility of the LNR is validated in other studies, it may replace the use of absolute number of axillary lymph nodes.
