Abstract
BACKGROUND Trastuzumab is an effective therapeutic approach for HER2-positive metastatic breast cancer (BC). However, a considerable number of patients develop resistance along the course of the disease. PTEN rs701848 polymorphisms are associated with an increased risk of developing cancer and have a potential role in predicting drug resistance. OBJECTIVE We studied the significance of PTEN rs701848 variants as significant predictors for trastuzumab resistance in HER2-positive metastatic BC patients. Therefore, considering their value in predicting clinical outcomes. MATERIALS AND METHODS This case-control study was conducted among female patients with HER2-positive metastatic breast cancer who underwent Trastuzumab therapy during the period from March 2017 to December 2020. PTEN rs701848 genotypes were analyzed in 160 HER2-positive metastatic breast cancer who received Trastuzumab therapy and clinically monitored for therapeutic response. RESULTS PTEN rs701848 is deemed a significant predictor of Trastuzumab resistance and an independent prognostic factor of progression-free survival (PPFS). In particular, the C allele is associated with increased risk for Trastuzumab resistance and shorter PFS as compared to the homozygous TT genotype. CONCLUSION PTEN rs701848 is significant predictor of trastuzumab resistance. Therefore, their value in predicting clinical outcomes is recommended.

Abstract
Diseases and infections of the respiratory tract are common global causes of morbidity and mortality. Our study attempts to elucidate a novel remedy for respiratory ailments, in addition to identifying and quantifying the metabolites of Saussurea costus root extract (SCRE) using HPLC. Then, in vitro antiviral and in vivo lung protective effects were elucidated. The in vitro antiviral potential of SCRE was analyzed via plaque assay against the low pathogenic human coronavirus (HCoV-229E) and human influenza virus (H1N1). The value of the half maximal inhibitory concentrations (IC50) of SCRE against HCoV-229E and H1N1 influenza virus were 23.21 ± 1.1 and 47.6 ± 2.3 µg/mL, respectively. SCRE showed a histological improvement, namely a decrease in inducible nitric oxide synthase (iNOS) and caspase-3 immunoexpression in in vivo cyclophosphamide (CP)-induced acute lung injury (ALI). Moreover, there was a considerable decline in microRNA-let-7a gene expression and a significant rise in heme oxygenase-1 (HO-1) gene expression, with a marked decrease in the malondialdehyde (MDA) level. Molecular docking studies revealed that the major constituents of SCRE have a good affinity for caspase-3, HO-1, and iNOS proteins. In conclusion, a traditional plant SCRE could be a promising source of novel therapeutic agents for treating and protecting respiratory tract diseases. More future investigations should be carried out to reveal its efficacy clinically.

Abstract
Background
IBD is a multifactorial disease. Although dysbiosis of commensal bacteria and breakdown of the intestinal barrier are considered as major pathological mechanisms in the development of IBD, other important factors such as genetic aberrations also contribute to its development.
Results
Our results revealed that serum miR-34a RQ values were significantly lower and serum MACF1 RQ values were significantly higher in IBD patients compared to healthy controls. In addition, serum miR-34a in relation to pathological activity and disease severity in the IBD group revealed a significant difference (p>0.05).
Conclusion
Serum miR-34a RQ and serum MACF1 RQ value-based biomarker panels can act as a potential biomarker for IBD diagnosis and prognosis.

Abstract
At the outpatient clinic of Ain Shams University Maternity Hospital, perceptions and practices of 1000 women regarding their reproductive health rights [reproductive rights] were evaluated. The majority had positive perceptions about their rights to reproductive health; however, 30% disagreed with prohibitions of discrimination against women, particularly prohibitions of female genital mutilation [FGM]. A significant association was found between perceptions of sexual rights and demographic characteristics and between education and practices regarding early detection of cancer. No significant association was found between education and concepts of adolescent health education as a reproductive right. Programmes about women’s reproductive rights that emphasize the issue of sexual health through religious education are recommended as one of the best strategies for the eradication of FGM

Abstract
BACKGROUND Mycosis fungoides is the most common type of primary cutaneous T cell lymphomas. Doxycycline promoted apoptosis in different human malignant cell lines and in vivo models. OBJECTIVES To test for the therapeutic efficacy of doxycycline in comparison to PUVA in early stages of classic MF and its effect on T cell apoptosis. METHODS Thirty-six patients were randomized into either: doxycycline 200 mg daily (n = 18) or PUVA (3 weekly sessions) (n = 18) for 12 weeks. The primary outcome (therapeutic efficacy) was defined in terms of objective response rate (ORR) which was measured according to changes in the modified severity weighted assessment tool (mSWAT). RESULTS Doxycycline achieved significantly less ORR (partial response) in comparison to PUVA (11.1%, 50%, respectively, p = .016). The percent reduction in mSWAT, CAILS, histopathology score and CD3 expression was significantly less in the doxycycline group (p = .001, p = .001, p ˂ .001, and p = .004, respectively). Within the doxycycline group, changes in mSWAT and CAILS showed no correlation with changes in the CD3 or Bcl-2 expression. Gastric upset was significantly more encountered in the doxycycline group (p = .001). CONCLUSION Doxycycline is not suitable as a sole agent in the treatment of early stages of classic MF, acting mainly by anti-inflammatory rather apoptotic function.

Abstract
The competing endogenous RNA networks play a pivotal role in cancer diagnosis and progression. Novel properstrategies for early detection of colorectal cancer (CRC) are strongly needed. We investigated a novel CRC-specific RNA-based integrated competing endogenous network composed of lethal3 malignant brain tumor like1 (L3MBTL1) gene, long non-coding intergenic RNA- (lncRNA RP11-909B2.1) and homo sapiens microRNA-595 (hsa-miRNA-595) using in silico data analysis. RT-qPCR-based validation of the network was achieved in serum of 70 patients with CRC, 40 patients with benign colorectal neoplasm, and 20 healthy controls. Moreover, in cancer tissues of 20 of the 70 CRC cases were involved in the study. The expression of RNA-based biomarker network in both CRC and adjacent non-tumor tissues and their correlation with the serum levels of this network members was investigated. Lastly, the expression levels of the chosen ceRNA was verified in CRC cell line. Our results revealed that the three RNAs-based biomarker network (long non-coding intergenic RNA-[lncRNA RP11-909B2.1], Homo sapiens microRNA-595 [hsa-miRNA-595], and L3MBTL1 mRNA), had high sensitivity and specificity for discriminating CRC from healthy controls and also from benign colorectal neoplasm. The data suggest that among these three RNAs, serum lncRNA RP11-909B2.1 could be a promising independent prognostic factors in CRC. The circulatory RNA based biomarker panel can act as potential biomarker for CRC diagnosis and prognosis.

Abstract
Background: The clinical value of inflammatory biomarkers is still questionable. Aim of the Work: The aim of this study is to compare the clinical informative value of procalcitonin (PCT) and C-reactive protein (CRP) plasma concentration in the early detection of sepsis, as well as relating these biomarkers to other scoring systems. Patients and Methods: A total of 138 patients were enrolled in our study. All were subjected to PCT, CRP, and sequential organ failure assessment (SOFA) scores daily for 7 days (starting from admission day). Blood samples were collected before starting antibiotics, with 28 days follow-up and patients were assigned to three groups: Group I: SOFA 2-7, Group II: SOFA 8-10, and Group III: SOFA ≥11. Results: Underlying clinical diagnosis revealed pneumonia in 72 patients, urinary tract infections in eight, bloodstream infection in four, and other infections in 23, while infection could not be traced in 25 patients. The mean PCT was 3 ng/ml (95% confidence interval [CI]: 1-4), 12 ng/ml (95% CI: 9.1-14), and 19 ng/ml (95% CI: 16.3-22.3) in Groups I, II, and III, respectively, with a statistically significant difference in the mean PCT level among the three groups (P < 0.0001). On the other hand, CRP mean level did not significantly differentiate between the groups (147.1 mg/L in Group II, which was even higher than the level of Group III, 138.4 mg/L). Conclusion: PCT seems to do better than CRP in predicting the SOFA groups, giving its patronage display over a wide spectrum of insults.

Abstract
Background Pemphigus vulgaris (PV) patients receiving immunosuppressive therapy may develop nail alterations resulting from infection, skin disorder, or drug regimen. Objective This study aims to describe nail changes in PV female patients receiving immunosuppressive therapy and to report the frequency of associated fungal and bacterial growth in the patients’ nails. Methods Twenty-five female PV patients who had at least one acquired finger or toenail abnormality and had been administered at least one immunosuppressive drug were included in the study. Nail alterations were recorded. Nail scrapings were collected from abnormal nails for fungal and bacterial examination. Results Positive fungal and bacterial cultures were detected in 20 (80%) of patients’ nail samples. Five patients reported nail alterations coinciding with disease onset, whereas 13 reported nail changes after administration of immunosuppressive therapy. Limitations Lack of a control group (patients on similar immunosuppressive medications for conditions other than PV) which would have further supported the findings demonstrated in this observational study. Conclusion Nail abnormalities in severe PV patients are frequently associated with fungal and bacterial growth. Immunosuppressive therapy potentially initiates such changes. What is already known on this topic? Pemphigus vulgaris (PV) patients receiving immunosuppressive therapy may develop nail alterations resulting from infection, skin disorder, or drug regimen.
What does this article add to our knowledge? The duration of disease in severe PV appears to dictate the longevity of nail changes in patients, and immunosuppressive therapy may initiate these nail changes either alone or as a result of opportunistic bacterial and/or fungal growth affecting the nail unit. Accordingly, prompt treatment of PV utilizing a multidisciplinary approach (combined or sequential therapy) would presumably decrease the incidence of nail affection in PV patients on immunosuppressive therapy. Limitations of the present work include lack of a control group (patients on similar immunosuppressive medications for conditions other than PV), which would have further supported the findings demonstrated in this observational study.

Abstract
BACKGROUND Chronic inflammation was found to play an important role in the development of cardiovascular risk factors. Homocysteine (Hcy) and fibrinogen have been identified as a major independent risk factor for cardiovascular disease. Lichen planus is assumed to be closely related to dyslipidaemia. Several cytokines involved in lichen planus pathogenesis, could explain its association with dyslipidaemia. Also chronic inflammation with lichen planus has been suggested as a component of the metabolic syndrome. OBJECTIVE The aim of this study was to detect a panel of cardiovascular risk factors in patients of lichen planus. PATIENTS AND METHODS This study was done on 40 patients of lichen planus and 40 healthy controls. All patients and controls were subjected to clinical examination. Serum levels of homocysteine, fibrinogen and high-sensitive C-reactive protein (hs-CRP) were measured by enzyme-linked immunosorbent assay technique (ELISA). Metabolic syndrome parameters including anthropometric measures, lipid profiles, blood sugar and blood pressure were studied. RESULTS Patients with lichen planus showed significant association with metabolic syndrome parameters than controls (P < 0.001). Serum homocysteine, fibrinogen and hs-CRP were significantly higher in lichen planus patients than controls (P < 0.001). Serum homocysteine correlated with both serum hs-CRP and serum fibrinogen. However, there was no correlation between serum levels of homocysteine and fibrinogen with any metabolic syndrome criteria and related disorders except for a negative correlation of fibrinogen with high-density lipoprotein (HDL). CONCLUSION In the present work, patients with lichen planus were found to have higher makers of both metabolic and cardiovascular risk factors in relation to controls most probably due to long standing inflammation.

Abstract
BACKGROUND Keratinocyte acantholysis as a result of pathogenic Dsg3-antibodies production by B cells leads to Pemphigus vulgaris (PV). Vitamin D, through its participation in several immune modulatory functions including B cells apoptosis, Th2 cell differentiation, apoptotic enzyme regulation and Tregs functions, may be actively involved in the immune regulation of PV. OBJECTIVE To evaluate Vitamin D status in PV patients in comparison to controls in an attempt to determine its role in this autoimmune disease. METHODS Using ELISA technique, 25-hydroxyvitamin D (25OHD) was determined for 34 pemphigus vulgaris patients and 20 healthy volunteers. Phosphorus and parathormone were also determined in the patient group. RESULTS 25OHD was significantly lower in patients than controls (P = 0.008). There was a statistically significant difference between both groups regarding suboptimal Vit. D levels (P = 0.007). CONCLUSION Patients with PV have significantly lower serum vitamin D levels in comparison to controls and that these low levels were not related to age, BMI or pattern of sun exposure. The associated Vitamin D insufficiency in patients with PV may possibly exacerbate their disease through various immune related mechanisms.

Abstract
This work aimed to assess the possible association between the presence of seminal mast cells and asthenozoospermia. One hundred and seventy-six male subjects were investigated: group (Gr)1 (n=46) normozoospermic fertile controls, Gr2 (n=62) idiopathic asthenozoospermia, Gr3 (n=32) asthenozoospermia with scrotal varicocele and Gr4 (n=36) asthenozoospermia with leucocytospermia. Four smear slides were prepared for each semen sample to be stained with toluidine blue-pyronin to detect mast cells. A significant increase was shown in mast cell-positive samples among varicocele-associated and idiopathic asthenozoospermic patients in comparison with fertile controls. Seminal mast cells were also detected at higher frequency among smokers and in age group over 40 years. It is concluded that mast cells and their products may play a pivotal role in the pathogenesis of asthenozoospermia, possibly proposing a new goal for medical treatment of infertile males to pursue. In addition, this concept may in a way detain smoking as a cause of male infertility considering the clear abundance of mast cells in semen samples of smokers.

Abstract
ABSTRACT At the outpatient clinic of Ain Shams University Maternity Hospital, perceptions and practices of 1000 women regarding their reproductive health rights (reproductive rights) were evaluated. The majority had positive perceptions about their rights to reproductive health; however, 30% disagreed with prohibitions of discrimination against women, particularly prohibitions of female genital mutilation (FGM). A significant association was found between perceptions of sexual rights and demographic characteristics and between education and practices regarding early detection of cancer. No significant association was found between education and concepts of adolescent health education as a reproductive right. Programmes about women's reproductive rights that emphasize the issue of sexual health through religious education are recommended as one of the best strategies for the eradication of FGM.
