Pelvic floor muscle training in mother fit healthcare centres: a best practice implementation project.

INTRODUCTION AND AIMS: Pelvic floor dysfunctions are common complications during the childbirth process. Pelvic floor muscle training (PFMT) has been used as a conservative treatment in both prenatal and postnatal women. The aim of this project was to assess the compliance with evidence-based criteria regarding PFMT among prenatal and postnatal women in mother fit healthcare centres. METHODS: The current study was performed in three phases. Phase 1: stakeholder engagement and team establishment and baseline audit. Phase 2: Design and implementation of strategies to improve PFMT among prenatal and postnatal women in mother fit healthcare centres. Phase 3: Follow-up audit. Baseline and follow-up audit with six yes/no audit questions was performed using the Joanna Briggs Institute Practical Application of Clinical Evidence System. Fifteen midwives involved in prenatal and postnatal healthcare centres and 60 pregnant women participated in this study. RESULTS: The compliance for each audit criterion found in the baseline audit was low (0-7%). However, after implementation of the project and training the trainers (midwives), the compliance increased significantly (77-100%). CONCLUSION: The current study demonstrated that we have some problems in the healthcare system to teach PFMT to pregnant women. We should also implement similar projects in all healthcare centres country wide. Healthcare system managers should be aware of the value of holding PFMT courses for pregnant women and it is recommended to use pelvic floor physiotherapists to train midwives.

The Prevalence of Allergic Rhinitis in Southwestern Iran and Its Association with Chronic Rhinosinusitis: A GA2LEN Study.

Allergic rhinitis (AR) is a prevalent disease affecting the quality of life of patients throughout the world. This study aimed to assess the prevalence of AR and its association with chronic rhinosinusitis (CRS) in the adult population living in Bushehr, southwestern part of Iran. In this population-based study, a total of 5420  individuals aged 15-65 years were selected through a multi-stage, cluster, random sampling method from which 5201 of them completed the Global Allergy and Asthma Network of Excellence (GA2LEN) questionnaire (Response rate=96.1%). The prevalence of AR, based on Allergic Rhinitis and Its Impact on Asthma (ARIA) classification (mild or moderate; intermittent or persistent) was calculated and the association of AR and CRS was evaluated using a multiple logistic regression model. The overall prevalence of AR was 28.8%, and for the intermittent and persistent AR were 25.9% (out of which 81.34% were moderate to severe) and 74.1% respectively. Moreover, the prevalence of AR was significantly higher in health workers and smokers (p=0.002 and p<0.001, respectively). Furthermore, an association was found between AR and CRS (p<0.001, aOR: 4.68, 95%CI: 4.07-5.39), and also, between the persistent AR and CRS as compared with the intermittent (p<0.001, aOR: 4.21, 95%CI: 3.40-5.22). The present study showed that the prevalence of AR in Bushehr (Southwestern part of Iran) was significantly high. In addition, the results indicated a strong association between AR and CRS, especially in individuals with moderate to severe persistent AR.

Establishment and Characterization of a New Triple Negative Breast Cancer Cell Line from an Iranian Breast Cancer Tissue.

Breast cancer is the most common malignancy and the leading cause of cancer-related death among women worldwide. The underlying mechanisms for breast cancer development, especially in young women, are not completely understood. Although there are several experimental models to understand the biology of breast cancer such as immortalized cell lines, many of these cell lines have been in culture for decades and most of them have been derived from Caucasians or African-Americans. So, it is required to establish a new cell line derived from primary tumors and Asian women. In this study Pari-Institute for Cancer Research (Pari-ICR) was derived from the primary breast tumor of a 36-years old patient with invasive ductal carcinoma. We characterized the cell line by examining morphology, expression of different markers, and functional profile. Immunocytochemistry showed that this cell line does not express estrogen and progesterone receptors as well as human epidermal growth factor receptor 2 (HER2). Pari-ICR cell line expresses high levels of Vimentin, Ezrin, and S100 but does not express EpCAM, Cytokeratin19, Pan-cytokeratin, Nestin, and Desmin. Its doubling time of Pari-ICR was about 22h and was able to grow as colonies in soft agar. It displayed a higher ability of migration and invasion in comparison with MCF-7 cell line. This breast cancer cell line can serve as a model for understanding the molecular mechanisms of breast carcinogenesis. Moreover, it can be used as an appropriate resource to find novel biomarkers or assess new drugs.

Production and characterization of monoclonal antibody against a triple negative breast cancer cell line.

Breast cancer is the most prevalent malignancy among women around the world such that more than 1,400,000 new cases are being diagnosed each year. Despite immense studies over many years on diagnosis and treatment of breast cancer, about 30% of treated patients will relapse and require subsequent therapy. By development of hybridoma technology, murine monoclonal antibodies (MAbs) against several human tumor-associated antigens have been produced and characterized in many laboratories. The purpose of these studies is to generate effective monoclonal antibodies that could be useful in tumor diagnosis and therapy. In this study, splenic lymphocytes of immunized BALB/c mouse with a new established breast cancer cell line (Pari-ICR cell line, established in Shiraz Institute for Cancer Research) were fused with the mouse myeloma cell line SP2/0 in the presence of polyethylene glycol. We generated a panel of monoclonal antibodies against the newly established cell line. The hybrid cultures were screened by flow cytometry. Hybridomas that produced antibody to surface antigens of immunizing cell line but not to Human Gingival Fibroblasts, adipose stem cells, and leucocytes isolated from peripheral blood were selected and cloned by limiting dilution method. The 1E3 clone (IgG2a type) that displayed clonal stability was further analyzed for specificity by flow cytometry. MAb 1E3 showed weak to strong reactivity to other cell lines compared with Pari-ICR cell line. Antigen identification was performed by a workflow consisting of immunoaffinity purification, SDS-PAGE, Western blotting, and mass spectrometry analysis. The target of 1E3 mAb was identified as NCAM1. In conclusion, using the antibody-based strategy we identified NCAM1 as a potential therapeutic target and biomarker for breast cancer.
