Obstetrician-gynecologists' perspectives towards medication use during pregnancy: A cross-sectional study.

A vast majority of studies evaluated pregnant women's knowledge and attitudes towards using medications during their pregnancy, with few global and lack of regional studies conducted to spot obstetrician-gynecologists practices in this regard. This study aims to assess Obstetrician-gynecologists' knowledge of medication teratogenicity potential, their frequently used resources, and their residency training contribution to medication use during pregnancy. This is a cross-sectional, survey-based study targeting licensed Obstetrician-gynecologists who are practicing in Saudi Arabia using a validated self-administered web-based questionnaire developed by the American College of Obstetricians and Gynecologists.

Factor XII deficiency in asymptomatic Saudi population: A retrospective cohort study.

Factor XII (FXII) deficiency is a rare genetic blood disorder. It can lead to a higher risk of developing deep vein thrombosis or acquired thrombotic disorders than the general population. This retrospective study evaluated patients who opted for surgery and were found to have abnormal clotting profiles and clotting factors on preoperative routine blood.

The translation and validation of the Arabic Version of the Polycystic Ovary Syndrome Health-Related Quality of Life Questionnaire (AR-PCOSQ).

Background: Polycystic ovarian syndrome (PCOS) is a hormonal disorder that is prevalent in females of reproductive age with signs and symptoms that significantly reduce self-esteem and have a negative impact on their quality of life. The management of PCOS signs and symptoms should result in an improvement in the health-related quality of life (HRQoL) of patients. Polycystic ovarian syndrome questionnaire (PCOSQ) is a disease-specific scale.

An experimental and algorithm-based study of the spectral features of breast cancer patients by a photodiagnosis approach.

In the present study, the spectral diagnosis of blood plasma samples of breast cancer patients and an equal number of normal controls was investigated. A set of ratio parameters was acquired by employing SXS and FES. The samples were also analyzed statistically by employing Welch two-sample t-tests, and the effects of three ratio parameters, R, R, and R, were also studied by plotting them against the subject numbers.

Association between cigarette & shisha smoking and the severity of polycythemia: A cross sectional study.

Tobacco cigarette smoking is assumed to be a key reason of death all over the world. Smoking had both severe as well long-lasting effects on hematological constraints. As per the data available from World Health Organization, every year nearly 5 million individuals die around the world due to the diseases triggered by smoking.

Molecular and biochemical investigations of key antioxidant/oxidant molecules in Saudi patients with recurrent miscarriage.

The present study was undertaken to: i) Determine the levels of oxidative stress (OS) markers, malondialdehyde (MDA), superoxide anions (SOA) and hydrogen peroxide (HO), in both plasma and placental tissues of recurrent miscarriage (RM) patients in comparison with those of healthy pregnant (HP) and non-pregnant (NP) women; ii) determine the levels of enzymatic antioxidants [glutathione peroxidase (GPx), glutathione reductase (GSR), superoxide dismutase (SOD) and catalase (CAT)], and non-enzymatic antioxidant micronutrients [selenium (Se), zinc (Zn), copper (Cu) and manganese (Mn)] in both plasma and placental tissues of RM patients, in comparison with those of HP and NP women; iii) profile differential expression levels of selected antioxidant and apoptosis-related genes in the placental tissues of RM cases, in relation to those of HP women of matched gestational age, using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The results revealed highly significant increases of all investigated OS markers in plasma and placental tissues of RM patients compared with those of HP women. Moderate, but significant, increases of OS markers were observed in the plasma of HP patients in relation to those of NP women.

Impact of Diabetes Mellitus on Human Erythrocytes: Atomic Force Microscopy and Spectral Investigations.

Diabetes mellitus (DM) is a common metabolic disease indicated by high sugar levels in the blood over a prolonged period. When left untreated, it can lead to long-term complications, such as cardiovascular disease, stroke, and diabetic retinopathy or foot ulcers. Approximately 415 million people (about 8.

A Novel Technique of Spectral Discrimination of Variants of Sickle Cell Anemia.

Sickle cell anemia (SCA) is an inherited blood disorder with worldwide incidence of 15%; out of this, it is found in up to 20% in countries like Kingdom of Saudi Arabia and Bahrain. The standard conventional method of detection is complete blood count (CBC) followed by hemoglobin electrophoresis or high-performance liquid chromatography (HPLC) or both. In this context, spectral detection of variants of sickle cell anemia (SCA) is an innovative technique, which when made accurate and reliable could be an effective alternative, since the instrumentation is compact (5 kg) and hence portable.

Toxicity of ar-curcumene and epi-β-bisabolol from Hedychium larsenii (Zingiberaceae) essential oil on malaria, chikungunya and St. Louis encephalitis mosquito vectors.

Mosquitoes act as vectors of key pathogens and parasites. Plant essential oils have been recognized as important sources of biopesticides, which do not induce resistance and have limited toxic effects on human health and non-target organisms. In this research, we evaluated the larvicidal and oviposition deterrence activity of Hedychium larsenii essential oil (EO) and its major compounds ar-curcumene and epi-β-bisabolol.

Attitudes of Saudi mothers towards breastfeeding.

The aim of the study was to explore the practice and attitudes of Saudi mothers towards breastfeeding. A cross-sectional survey done on a total of 517 Saudi mothers using a questionnaire inquiring about their demographic data, breastfeeding practice in the first 6 months after delivery and longer, different reasons for stopping breastfeeding. Furthermore, their impression on the relation between breastfeeding and breast cancer as well as prevention of infant's allergic and infectious diseases.

Superoxide dismutase activity and gene expression levels in Saudi women with recurrent miscarriage.

The antioxidant activities of superoxide dismutase 1 (SOD1) and SOD2, as well as the levels of the oxidant superoxide anion (SOA) and the micronutrients zinc (Zn), copper (Cu) and manganese (Mn), were assayed in plasma, whole blood and placental tissue of non‑pregnant (NP), healthy pregnant (HP) women and recurrent miscarriage (RM) patients. The results showed that SOD1 and SOD2 activities and the levels of Zn, Cu and Mn in plasma and whole blood of HP women were slightly, but significantly lower, and even more significantly decreased in RM patients compared to those observed in NP women (P<0.05 and P<0.

Biochemical Markers of Oxidative Stress in Saudi Women with Recurrent Miscarriage.

This study was undertaken to investigate the antioxidant/oxidant status in recurrent miscarriage patients. Antioxidants including glutathione peroxidase (GPx), catalase (CAT), glutathione reductase (GR), reduced glutathione (GSH) and selenium (Se), as well as the oxidants hydrogen peroxide (H2O2), oxidised glutathione (GSSG) and lipid peroxidation were assayed in plasma, whole blood and placental tissue of non-pregnant women (NP), healthy pregnant women (HP), and recurrent miscarriage (RM) patients. Results indicated that all antioxidant activities and levels in plasma and whole blood of HP women were consistently moderately lower, and much more significantly lower in RM patients when both were compared to those seen in NP women (P<0.
