Analysis of frequency of congenital fetal anomalies diagnosed on antenatal ultrasound in a tertiary care hospital of Balochistan

Background: The objective of our study is to check the incidence of various congenital fetal anomalies in antenatal period by ultrasonography in a subset of population.Methods: This cross sectional study was conducted in the department of Radiology, Bolan Medical Complex Hospital Quetta from November 2017 to October 2018. Total of 1323 second and third trimester pregnancies were analyzed for a period of one year. 34 fetal anomalies were detected making the prevalence of 2.5%. Information obtained from history, clinical examination and Ultrasound examination were recorded. The data was analyzed in SPSS 20.These patients were also interviewed for folic acid supplementation and consanguineous marriage.Results: 1323 patients were examined with congenital abnormalities detected in 34 fetuses. Among 34 fetuses, 20 were male and 14 were female fetuses. Out of 34, mother of 24 fetuses verified that they did not take folic acid supplementation. Consanguineous marriage recognized as the important risk factor as found in 22 congenital abnormal fetus.  CNS anomalies were the most commonly occurring anomalies with prevalence of (0.9%) followed by gastrointestinal tract anomalies (0.3%) and Urinary tract anomalies (0.3%).Conclusions: The fetus prognosis largely depends on early detection of its any congenital anomaly on antenatal ultrasound as they can result in abortions, still births and other fetal defects. So antenatal ultrasound is very important and safe method for early detection and management of fetal anomalies

COVID-19 and Pregnancy Outcome: An Experience in ‘COVID-19 Management Designated’ Tertiary Care Hospital, Rawalpindi, Pakistan

Background: The current COVID-19 pandemic has affected almost 17.3 million victims worldwide with mortality of almost 674K. Pregnancy is one of the most susceptible conditions for COVID-19 infection, but limited data is currently available about the clinical characteristics of pregnant women with the disease. Objective; to describe the clinical characteristics, co-morbidities, management, feto-maternal, and neonatal outcome in COVID-19 positive pregnant women. Methodology: A descriptive case series study was conducted in Obs/Gynae dept of Benazir Bhutto Tertiary Care Hospital, Rawalpindi, including all asymptomatic/symptomatic COVID-19 positive pregnant women and clinical suspects (COVID-19 PCR negative women) delivered in our hospital from 01st April 2020 to 31st July 2020. Their medical records were reviewed for clinical characteristics, management, feto-maternal and neonatal outcomes. Continuous variables were expressed in Mean & Range and Categorical variables as number & Percentage. Results: During the study period a total of 17 cases were reviewed. The mean maternal age was 28.94 yrs. Primigravida (07), Multipara (10). Mean gestational age was 37 wks (range; 30-41wks). Presenting symptomatology was varied. Asymptomatic; (29%), COVID-19 specific symptoms; fever & flu (12%), fever&cough (6%), shortness of breath(SOB) alone (6%), fever & SOB(6%) and pregnancy-related manifestations were labour pains (17%), eclampsia(6%), hydrocephalous fetus (6%) and hepatic encephalopathy(6%). The commonest co-morbidity was Hypertensive disorders of pregnancy (24%). Five women (29%) required ICU care. Lower segment caesarean sections(LSCS) (59%), vaginal delivery (41%). Eleven babies delivered with good Apgar score and birth weight. Two were early neonatal deaths (ENND) and 04 were received intra-uterine fetal deaths (IUDs). Fetal demise was associated with strong obstetric risk factors. Out of 13 live-born babies, RT-PCR Covid-19 testing was done in 10 (77%) cases and was negative. One mother was expired due to complications of hepatic encephalopathy, sepsis, and burst abdomen. Conclusion; The clinical course of COVID-19 disease in pregnancy seems to be no different from non-pregnant women. Clinical manifestations are diverse and infection contracted in the third trimester of pregnancy is associated with good feto-maternal and neonatal outcomes

Microbial Fuel Cell Formulation from Nano-Composites

Petroleum and oil industry is a rich source of nonrenewable energy that ultimately results in threatening of ecosystem due to emission of greenhouse gases into the environment. In the current panorama of the energy demand, industries focus on alternate and renewable energy resources to meet energy gaps. Thus, an expedient fuel cell based on microbes can be valued as an economical and ecofriendly substitute of energy generator. These microbial fuel cells have commercialized platinum electrodes to generate cost-effective energy after oxidation of organic wastes catalyzed by biocatalyst. Nowadays, conventional carbon electrode as an anode is taking popularity in microbial fuel cell but displays poor performance. So, to improve the chemistry of electrodes, nano-composites fabricated from polar polymeric material as well as cost-effective oxides of metals are the raw material. In this chapter, green synthesis of nano-composites from conducting polymers and oxides of transition metals has been discussed. Anode modification by composite to treat wastewater as well as its role to generate electricity has been discussed briefly

High ALDH Activity Identifies Chemotherapy-Resistant Ewing's Sarcoma Stem Cells That Retain Sensitivity to EWS-FLI1 Inhibition

Cancer stem cells are a chemotherapy-resistant population capable of self-renewal and of regenerating the bulk tumor, thereby causing relapse and patient death. Ewing's sarcoma, the second most common form of bone tumor in adolescents and young adults, follows a clinical pattern consistent with the Cancer Stem Cell model - remission is easily achieved, even for patients with metastatic disease, but relapse remains frequent and is usually fatal.We have isolated a subpopulation of Ewing's sarcoma cells, from both human cell lines and human xenografts grown in immune deficient mice, which express high aldehyde dehydrogenase (ALDH(high)) activity and are enriched for clonogenicity, sphere-formation, and tumor initiation. The ALDH(high) cells are resistant to chemotherapy in vitro, but this can be overcome by the ATP binding cassette transport protein inhibitor, verapamil. Importantly, these cells are not resistant to YK-4-279, a small molecule inhibitor of EWS-FLI1 that is selectively toxic to Ewing's sarcoma cells both in vitro and in vivo.Ewing's sarcoma contains an ALDH(high) stem-like population of chemotherapy-resistant cells that retain sensitivity to EWS-FLI1 inhibition. Inhibiting the EWS-FLI1 oncoprotein may prove to be an effective means of improving patient outcomes by targeting Ewing's sarcoma stem cells that survive standard chemotherapy

Background: To determine the frequency of various gynaecological malignancies and to describe the age distribution, stage and clinical presentation of various gynaecological malignancies.Methods: In this descriptive study all patients with Gynecological malignancies were included in the study irrespective of the age and stage of the diseases.Patients with breast cancer associated with Pelvic Cancer were excluded from the study.Clinical data was collected from the patients by taking history and performing relevant examination and filling up the attached questionnaire/ performa.Results: There were 15 cases with ovarian cancer, nine of cervical cancer, three cases of endometrial cancer, two cases of vulvar cancer and one case of chorio carcinoma. Age of the patients with cervical cancer ranged from 45-67 years. Endometrial cancer presented at mean age of 56 years. In ovarian cancer age of patients ranged from 24-63 years. The mean age of patients with vulvar cancer was 72.5 years. The age of the patient with choriocarcinoma was 32 years. Weight loss, vaginal bleeding and discharge, menstrual irregularities, post menopausal bleeding were common clinical manifestations . Most of the patients, in all types, presented in late stages.Conclusion: Patients with gynecological malignancies have good prognosis, if cancer is detected at an early stage. Therefore efforts should be made to encourage women to seek medical advice at first abnormal symptom

The Correlation of Sexual Dysfunctions with Chronic Pelvic Pain

Background: To describe the correlation of sexual problems in patients presenting with chronic pelvic painMethods: In this descriptive study, female patients (n=100) sufferer of chronic pelvic pain were included . Their sexual behaviour was assessed by using the questionnaire of Derogatis Interview for Sexual Functioning- Self Report (DISF-SR). This questionnaire contains 5 items which were given scores. A total score was then calculatedResults: Patients presenting with chronic pelvic pain having sexual dysfunction were 71% compared with 29% who were sufferer of chronic pelvic pain but without sexual problems. Mean age, BMI and socioeconomic status (monthly family income) was 33. Mean total sexual functioning score of our study sample was 38.28 ± 3.54 while mean and standard deviation for sexual disorders were 9.04± 1.55, 7.12 ± 1.28, 11.23 ± 1.69 and 11.20 ± 1.89 for sexual arousal, behaviour, orgasm and sexual drive respectively.Conclusion: Patients with chronic pelvic pain have some degree of sexual dysfunction and they may suffer from various sexual disorders which need to be assessed so that measures should be undertaken to help these patients to cope with pain and sexual disorders and so they can live a healthy life

Mutagenesis of DsbAss is Crucial for the Signal Recognition Particle Mechanism in <i>Escherichia coli</i>: Insights from Molecular Dynamics Simulations

The disulfide bond signal sequence (DsbAss) protein is characterized as an important virulence factor in gram-negative bacteria. This study aimed to analyze the &#8220;alanine&#8222; alteration in the hydrophobic (H) region of DsbAss and to understand the conformational DsbAss alteration(s) inside the fifty-four homolog (Ffh)-binding groove which were revealed to be crucial for translocation of ovine growth hormone (OGH) to the periplasmic space in Escherichia coli via the secretory (Sec) pathway. An experimental design was used to explore the hydrophobicity and alteration of alanine (Ala) to isoleucine (Ile) in the tripartite structure of DsbAss. As a result, two DsbAss mutants (Ala at positions -11 and -13) with same hydrophobicity of 1.539 led to the conflicting translocation of the active OGH gene. We performed molecular dynamics (MD) simulations and molecular mechanics generalized born surface area (MM-GBSA) binding free energy calculations to examine the interaction energetic and dynamic aspects of DsbAss/signal repetition particle 54 (SRP54) binding, which has a principle role in Escherichia coli Sec pathways. Although both DsbAss mutants retained helicity, the MD simulation analysis evidenced that altering Ala-13 changed the orientation of the signal peptide in the Ffh M binding domain groove, favored more stable interaction energies (MM-GBSA &#916;Gtotal = &#8722;140.62 kcal mol&#8722;1), and hampered the process of OGH translocation, while Ala-11 pointed outward due to unstable conformation and less binding energy (&#916;Gtotal = &#8722;124.24 kcal mol&#8722;1). Here we report the dynamic behavior of change of &#8220;alanine&#8222; in the H-domain of DsbAss which affects the process of translocation of OGH, where MD simulation and MM-GBSA can be useful initial tools to investigate the virulence of bacteria

Mutagenesis of DsbAss is Crucial for the Signal Recognition Particle Mechanism in Escherichia coli: Insights from Molecular Dynamics Simulations

The disulfide bond signal sequence (DsbAss) protein is characterized as an important virulence factor in gram-negative bacteria. This study aimed to analyze the "alanine" alteration in the hydrophobic (H) region of DsbAss and to understand the conformational DsbAss alteration(s) inside the fifty-four homolog (Ffh)-binding groove which were revealed to be crucial for translocation of ovine growth hormone (OGH) to the periplasmic space in Escherichia coli via the secretory (Sec) pathway.
