887, 4.790 & p less then 0.05), respectively. Multiple regression shows that age (b=0.302, t=-2.795, p=0.007), education (b=0.336, t=2.425, p=0.019), mothers' education (b=0.314, t=2.345, p=0.023), and monthly income (b=-0.337, t=-2.503, p=0.015), are significant predictors of PMSGC knowledge. Furthermore, age (b=0.659, t=4.024, p=0.000), residence (b=0.293, t=2.233, p=0.030), education (b=-0.395, t=3.028, p=0.004), and type of disability (b=-0.443, t=-3.763, p=0.000) are significant predictors of PMSGC attitude. Although most deaf and hard hearing females have incorrect knowledge regarding PMSGC, most have a positive attitude. The study concluded that participants' education, mothers' education, and monthly income are significant predictors of PMSGC knowledge. Moreover, age, residence, education, and type of disability were significant predictors of higher PMSGC attitudes.This study aimed to evaluate metformin as a widely used oral hypoglycemic agent and identify the effects on biochemical and antioxidant body systems of rabbits. Four groups of rabbits were randomly allocated as the control, the alloxan-induced diabetic, metformin-treated, and alloxan treated with metformin. The results revealed that alloxan leads to significant elevation in glucose (Glc) levels, malondialdehyde (MDA), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), triglycerides (TGs), and total cholesterol (TCH), and a significant decline in high-density lipoprotein (HDL) and glutathione (GSH) as compared with the control group. Metformin alone caused a significant decline in Glc and HDL with significant elevation in LDL and MDA without significant changes in TCH, TGs, VLDL, and GSH. When metformin was offered as a treatment for alloxan-induced diabetic animals, it caused a significant decline in Glc, TCH, TGs, LDL, and VLDL levels with significant elevation in GSH and without a significant change in HDL and MDA. Metformin causes a decline in glucose levels due to its ability to decrease the use of substances hepatic cells use to create glucose and its ability to induce the enzymes participating in glucose oxidation.Endometrial pathology, including hyperplastic processes in the structure of reproductive disorders, occupies one of the leading places along with inflammatory diseases of the pelvic organs, contributing to infertility in 80% of cases and irregular menstrual cycle in 40-43%. This study aims to optimize the diagnostic algorithm in patients with endometrial hyperplasia combined with chronic endometritis and determine qualitative indicators of compression sonoelastography in patients with endometrial pathology and infertility. A comprehensive clinical and laboratory examination of 90 infertile patients aged 25 to 45 years with endometrial hyperplasia combined with chronic inflammation, retention cysts, and benign ovarian tumors was carried out. The results of clinical-laboratory and complex ultrasound examination with compression sonoelastography were compared with the data of pathomorphological and immunohistochemical studies. A high percentage of pelvic inflammatory disease (55.0%), benign lesions of the cervix (67.5%), hyperplastic processes of the myometrium (37.5%), an increasing number of polyps by 2.9 times, leiomyomas and adenomyosis - by 2.3 times (p less then 0.05) was established. In the case of a combination of endometrial hyperplasia and ovarian cysts, a high percentage of comorbidity of gynecological pathology is verified (37.8%), and the use of compression sonoelastography allows to establish class II and class III elastograms in 91.1% of cases which characterize benign endometrial lesions, reduce the number of false-positive results in 95.6% of cases, correctly interpret the nature of pathological changes and increase the sensitivity of ultrasound techniques.The COVID-19 pandemic has tremendously increased the production and sales of disinfectants. This study aimed to systematically review and analyze the efficacy and safety of chlorine dioxide as a disinfectant. The literature relating to the use of chlorine dioxide as a disinfectant was systematically reviewed in January 2021 using databases such as PubMed, Science Direct, and Google Scholar. Inclusion criteria were studies that investigated the use of chlorine dioxide to assess the efficacy, safety, and impact of chlorine dioxide as a disinfectant. Out of the 33 included studies, 14 studies focused on the disinfectant efficacy of chlorine dioxide, 8 studies expounded on the safety and toxicity in humans and animals, and 15 studies discussed the impact, such as water treatment disinfection using chlorine dioxide. Chlorine dioxide is a safe and effective disinfectant, even at concentrations as low as 20 to 30 mg/L. Moreover, the efficacy of chlorine dioxide is mostly independent of pH. Chlorine dioxide can be effectively used to disinfect drinking water without much alteration of palatability and can also be used to destroy pathogenic microbes, including viruses, bacteria, and fungi from vegetables and fruits. Our review confirms that chlorine dioxide is effective against the resistant Mycobacterium, H1N1, and other influenza viruses. Studies generally support the use of chlorine dioxide as a disinfectant. The concentration deemed safe for usage still needs to be determined on a case-by-case basis.Pregnancy is a unique condition for women, associated with physiological and emotional changes in the body. Various research showed an association between periodontal disease and adverse pregnancy outcomes. Importance to hygiene maintenance should be given during pregnancy and improve the wellbeing of the mother and child. This study assessed oral health knowledge, attitude, and practices among pregnant women in Hyderabad. The study design was cross-sectional and included 445 women who responded and completed the survey. Subjects were selected using a random sampling technique in gynecology clinics. The questionnaire form consisted of four sections demographic data, knowledge, attitude, and oral hygiene practice. Out of the 482 pregnant females invited to participate in the study, 445 women completed the survey, giving a response rate of 92%. The majority of women showed good knowledge and attitude regarding oral hygiene and its relation to pregnancy. However, the participants showed poor compliance with the recommended protocol. There are certain myths and barriers to dental treatment that need to be considered in the prenatal education of women. If explained by the gynecologist, the importance of oral health and its correlation with systemic health will play a crucial role in improving oral hygiene practice and regular dental visits.This study aimed to assess vitamin D status and its association with iron status in young Iraqi children. A total of 95 infants and toddlers with iron deficiency (ages ranging from 6 to 24 months) and an equal number of 95 healthy subjects with normal hemoglobin (Hb) and sufficient ferritin level with matching age were included as a control group. A specially designed questionnaire was used to collect data. The cases were classified into iron deficiency (ID) and iron deficiency anemia (IDA) according to hemoglobin and ferritin levels. The cases and control groups were subdivided into vitamin insufficiency (VDI), vitamin D deficiency (VDD), and vitamin D sufficiency groups according to 25-hydroxyvitamin D [25(OH)D] levels. Young children with IDA have significantly lower serum levels of 25(OH) D compared with ID and control groups (p less then 0.05). According to iron status, VDI and VDD were present in 20% and 70% of IDA, 25.7% and 60%of ID, and 26.3% and 30.5% of control groups, respectively, with a significant difference in vitamin D level (p less then 0.05) among studied groups. A significant positive correlation (p=0.000) was found between serum ferritin level and 25(OH) D level in studied patients. Young children with severe iron deficiency have a higher prevalence of vitamin D deficiency, and there was a significant positive correlation between serum ferritin level and 25(OH) D levels among studied children.COVID-19 is a pandemic disease caused by SARS-CoV-2, which is an RNA virus similar to the hepatitis C virus (HCV) in the replication process. click here Sofosbuvir/ledipasvir is an approved drug to treat HCV infection. This study investigates the efficacy of Sofosbuvir/ledipasvir as a treatment for patients with moderate COVID-19 infection. This is a single-blinded parallel-randomized controlled trial. The participants were randomized equally into the intervention group that received Sofosbuvir/ledipasvir (S.L. group), and the control group received Oseltamivir, Hydroxychloroquine, and Azithromycin (OCH group). The primary outcomes were the cure rate over time and the incidence of serious adverse events. The secondary outcomes included the laboratory findings. 250 patients were divided equally into each group. Both groups were similar regarding gender, but age was higher in the S.L. group (p=0.001). In the S.L. group, 89 (71.2%) patients were cured, while only 51 (40.8%) patients were cured in the OCH group. The cure rate was significantly higher in the S.L. group (RR=1.75, p less then 0.001). Kaplan-Meir plot showed a considerably higher cure over time in the S.L. group (Log-rank test, p=0.032). There were no deaths in the S.L. group, but there were six deaths (4.8%) in the OCH group (RR=0.08, p=0.013). Seven patients (5.6%) in the S.L. group and six patients (4.8%) in the OCH group were admitted to the intensive care unit (ICU) (RR=1.17, P=0.776). There were no significant differences between treatment groups regarding total leukocyte and neutrophils count, lymph, and urea. Sofosbuvir/ledipasvir is suggestive of being effective in treating patients with moderate COVID-19 infection. Further studies are needed to compare Sofosbuvir/ledipasvir with new treatment protocols.Malaria is the most severe protozoan disease in the world. As a result of strict malaria control programs, malaria's epidemiological model has changed. Knowing this epidemiological model and its effects will help us predict and prevent a new epidemic. This research was conducted to review the epidemiological trend of malaria in the Kermanshah province of Iran and some of its effective factors. Data were extracted from the registers in the disease control unit of the province, national population census, and annual rainfall report. The data was processed by SPSS16. There has been an evident decrease in malaria cases over the last 30 years in Kermanshah. This decreasing trend began especially after 1994, and since then, just 6% of all cases have happened. Between 1990 to 1997, an epidemic occurred, and more than 80% of positive cases were registered in these years. P. vivax malaria was the most common type (99.32%), and P. falciparum malaria was the second, with a very egregious difference (0.68%). The average age was 23.1 years, and men were infected twice more than women. There was a positive relation between annual rainfall level and positive malaria cases in these cities. After the major changes in malaria control programs in Kermanshah province, the number of positive cases fell noticeably, and now it is in the elimination stage. All cases of malaria were imported in the last years, and no resistance type was ever seen.
