Metals are essential cofactors that play a crucial role in heart function at the cell and tissue level. Information regarding the role of metals in the pericardial fluid and its ionome in ischemic heart disease (IHD) is limited. We aimed to determine the association of elements in pericardial fluid and serum samples of IHD patients and their correlation with systolic and diastolic function. IHD patients have been studied with systolic and diastolic dysfunction categorized on the basis of echocardiographic parameters. We measured concentrations of sixteen elements in the pericardial fluid and serum of 46 patients obtained during open heart surgery …

Ischemic heart disease (IHD) is the leading cause of death and chronic disability in the world. IHD affects both the systolic and diastolic function of the heart which progressively leads to heart failure; a structural and functional impairment of filling or ejection of blood from the heart. In this study, the progression of systolic and diastolic dysfunction characterized according to their echocardiographic parameters including left ventricular ejection fraction (EF), grades of diastolic dysfunction and ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/e'), were correlated with differential regulation of various metals in patients sera samples (n …

Clinicopathologic Features Predictive Of Distant Metastasis In Patients Diagnosed With Invasive Breast Cancer, Basim Ali, Fatima Mubarik, Nida Zahid, Abida K. Sattar Aug 2020

Clinicopathologic Features Predictive Of Distant Metastasis In Patients Diagnosed With Invasive Breast Cancer, Basim Ali, Fatima Mubarik, Nida Zahid, Abida K. Sattar

Department of Biological & Biomedical Sciences

Purpose: National Comprehensive Cancer Network and European Society for Medical Oncology guidelines suggest screening for distant metastasis (M1) in symptomatic patients or those with locally advanced breast cancer. These guidelines are based on studies that often used pathologic staging for analysis. Physician variability in screening for M1 has also resulted in overuse of diagnostic tests. We sought to identify clinicopathologic features at diagnosis that could guide testing for metastatic disease.
Methods: Patients diagnosed with invasive breast cancer between January 2014 and December 2015 were identified from our institutional database. Demographic and clinical variables were collected, including receptor profiles and clinical …


Role Of Oxidative Stress And Altered Thyroid Hormones In Unexplained Infertility, Rehana Rehman, Hiba Ismail Rajpar, Mussarat Ashraf, Najeeha Talat Iqbal, Salima Lalani, Faiza Alam Aug 2020

Role Of Oxidative Stress And Altered Thyroid Hormones In Unexplained Infertility, Rehana Rehman, Hiba Ismail Rajpar, Mussarat Ashraf, Najeeha Talat Iqbal, Salima Lalani, Faiza Alam

Department of Biological & Biomedical Sciences

Objective: To explore the link between altered thyroid profile and oxidative stress marker in females with unexplained infertility.
Methods: The cross-sectional case-control study was carried out at the Islamabad Clinic Serving Infertile Couples, Islamabad, Pakistan, from June 2016 to August 2017, and comprised women aged 18-40 years regardless of ethnic background who were divided into two groups; those with unexplained infertility were the cases, while fertile women acted as the controls. Serum was analysed for triiodothyronine, thyroxine and thyroid stimulating hormone as well as for oxidative stress markers including manganese superoxide dismutase, glutathione reductase and adrenaline using enzymelinked immunosorbent assay. …


Association Of Circulatory Kisspeptin Levels And Hormonal Interplay With Male Infertility: A Cross-Sectional Study In Karachi, Pakistan, Rehana Rehman, Kaleem Ahmed, Nida Zahid, Faiza Alam, Syeda Sadia Fatima Jul 2020

Association Of Circulatory Kisspeptin Levels And Hormonal Interplay With Male Infertility: A Cross-Sectional Study In Karachi, Pakistan, Rehana Rehman, Kaleem Ahmed, Nida Zahid, Faiza Alam, Syeda Sadia Fatima

Department of Biological & Biomedical Sciences

Objectives: To determine the impact of Kisspeptin on male reproductive axis in a selected urban population.
Methods: The cross-sectional study was conducted at the Sindh Institute of Reproductive Medicine in collaboration with Aga Khan University, Karachi, from July, 2017, to February, 2018, and comprised infertile males with abnormal sperm parameters who were placed in Group A and fertile males with normal sperm parameters placed in Group B. Serum samples were estimated for Kisspeptin, follicle stimulating hormone, luteinizing hormone, testosterone and sex hormone-binding globulin using enzyme-linked immunosorbent assay. Data was analysed using SPSS 22.
Results: Of the 313 male subjects, 178(57%) …


Follicular Sensitivity Index: A Tool To Predict Successful Conception After Intra-Cytoplasmic Sperm Injection, Rehana Rehman, Amara Zafar, Nida Zahid, Nuruddin Badruddin Mohammed Apr 2020

Follicular Sensitivity Index: A Tool To Predict Successful Conception After Intra-Cytoplasmic Sperm Injection, Rehana Rehman, Amara Zafar, Nida Zahid, Nuruddin Badruddin Mohammed

Department of Biological & Biomedical Sciences

Follicular sensitivity index (FSI) is used for estimation of follicular responsiveness to controlled ovarian hyperstimulation (COH) during intra-cytoplasmic sperm injection (ICSI). In a retrospective study, FSI of 1,385 females was calculated as [pre-ovulatory follicle count (PFC) × 100,000]/ [antral follicle count (AFC) × total received stimulation doses]. Females were then categorised into low, middle and high FSI groups according to FSI tertile values. FSI was 8.65 ±2.82 in non-pregnant as compared to 12.02 ±2.04 (p <0.01) in pregnant cohort. FSI turned out to be a strong predictor of successful conception on the receiver operating curve with cutoff value 10.36 at 76% specificity, sensitivity of 86% and area under the curve (AUC; 0.83). Calculation of FSI can thus predict the chances of successful conception in females with different causes of infertility.

Neurodevelopment Outcome Of Neonates Treated With Intraventricular Colistin For Ventriculitis Caused By Multiple Drug-Resistant Pathogens-A Case Series, Kashif Hussain, Muhammad Sohail Salat, Gul Ambreen, Javaid Iqbal Jan 2020

Neurodevelopment Outcome Of Neonates Treated With Intraventricular Colistin For Ventriculitis Caused By Multiple Drug-Resistant Pathogens-A Case Series, Kashif Hussain, Muhammad Sohail Salat, Gul Ambreen, Javaid Iqbal

Department of Biological & Biomedical Sciences

Background: Multiple-drug-resistant Gram-negative bacteria (MDR-GNB)-associated neonatal ventriculitis is a life-threatening complication that needs timely diagnosis and effective treatment with broad-spectrum antimicrobials in critical-care settings. Inadequate penetration of antibiotics through the blood-brain barrier also demands an intraventricular (IVT) route of administration. This study reports mortality and neurodevelopmental sequelae of neonates till 18 months of age, who received IVT-colistin for treating MDR-GNB associated ventriculitis.
Methods: In a case series of seven neonates with ventriculitis due to MDR-GNB at NICU of Aga Khan University Hospital, Pakistan, between June 2015 and 2018, we reviewed IVT-colistin therapy in critically ill neonates. Treatment outcomes were assessed …
