In humans, the role of Q fever during pregnancy has been recently questioned. Objectives: Thus, the goal of this study was to investigate the seroprevalence of C. Burnett infection among pregnant women in Gezira state, Sudan as well as the relationship between spontaneous recurrent abortion and pregnancy. Methods: This study included 90 women, half of whom had recurrent spontaneous abortion (RSA) and the other half had successful pregnancies. Blood samples were taken simply randomly, with ethical considerations, and using open ended closed questionnaire, prepared samples, and kept at -20°C. The seroprevalence of IgG and IgM antibodies against C. burnetti was determined using a commercial enzyme-linked immunosorbent assay test kit. Means of frequencies plus standard error, Chi2, and in depending sample t-test and logistic regression univariate and multivariate tests have been used. Result: The overall prevalence of C. burnetii in the study population sera was (37/90) 41.11 percent, with 5(11.1%) and 11(24.4 %) positive miscarriages in pregnant women for C. Burnetti IgM and IgG, respectively. While in nonmiscarriage were 8 (17.8 %) and 13 (28.9 %) positive for IgM (OR .578, CI-95% .174-1.926, P .372), and IgG (OR .796, CI-95% .312-2.032, P .634), respectively. Other significant risk factors detected in the study were age(OR 5, CI-95% 2-13, P 0.001), biomax index (OR 5, CI-95% 2-12, P 0.001), Diabetic patients (OR 11,1CI-95% 11 -11.38 P 0.000), disorder of thyroid (OR 8,9 CI-95% 8.1 -9 P 0.000), microcytic hypochromic anemia (OR 11, CI-95% 1.1 -110.2 P 0.04), Menstruation Cycle (OR 3.8, CI-95% 1.2 -11.5, P 0.02), vaginal bleeding(OR 6.4 CI-95% 2.1-19.2, P 0.001), pre-eclampsia(OR 16.1, CI-95% 1.9-131.1, P 0.01), and miscarriage family history(OR 2.9, CI-95% 2.8 -9.8, P 0.000), RDWC(OR 4.4, CI-95% 1.8 -10.9, P 0.002), RDWSD (OR 19.2 CI-95% 5.2 -71.1, P 0.000).

However, a definite and reliable mechanism of CSF is still not known. Short-chain fatty acids (SCFA) such as acetate, butyrate, and propionate are produced as a result of the fermentation of indigestible dietary fibres in the gut by the microbiota. Many studies have investigated the role of SCFA as a related signalling pathway in inflammation, glucose metabolism, and lipid metabolism. In this study, we investigated the correlation between Short Chain Fatty Acids and Lipid Profile serum in Patients with Slow Flow Coroner. Materials and Methods: 50 patients who were referred to the Department of Internal Medicine, Muzaffarnagar Medical College, Muzaffarnagar, were selected based on inclusion and exclusion criteria. Data was obtained through laboratory examination and stool samples. Stool samples were analyzed for SCFA (acetate, propionate, and butyrate acids) with gas chromatography. Results: The results of the present study indicate that SCFA, acetate, propionate, and valerate did not show a significant correlation with lipid profile (P>0.05). The level of fecal butyrate was negatively correlated with HDL (p=<0.05; r = -0.532). Conclusions: Our study indicated that the level of butyrate was a moderate negative correlated with HDL inpatient with slow flow coroner.","PeriodicalId":478944,"journal":{"name":"Middle East Research Journal of Medical Sciences","volume":"178 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are considered to be a population at high risk of developing HBV infection due to the high transmissibility of the virus and the risk related to occupational injuries. The risk is particularly high in HCWs with greater exposure to accidental inoculation at work and is related to the duration of professional activity, the characteristics of the healthcare center, and the type of population served. Objectives: The current study was conducted to evaluate the immunity status of the vaccinated HCWs against HBV in Khartoum State. Materials and Methods: This cross-sectional descriptive laboratory-based study was conducted from December 2022 to February 2023. Data were collected through a structured questionnaire regarding age, gender, type of employment, length of employment, and duration of vaccination for each participant. 90 vaccinated HCWs were enrolled in this study; serum samples were collected from each participant; the Enzyme Linked Immuno Sorbent Assay technique was used to detect the anti-HBs level; and the collected data were analyzed using Statistical Package for the Social Sciences (SPSS). Results: This study included 90 healthcare workers, female 70 (77.8%), male 20 (22.2%) ages ranging from 20 to 52 years old, 45 (50%) of them laboratory specialists, and 23 (23.3%). Nursing 17 (18.9%), Dentists 5 (5.6%), and 2.5 (2.2%). The results of the current study reveal that 70% of the studied vaccinated HCWs have a protective level of HBs-Ab. Of these, 23.3% had an anti-HBs titer between 10 and 100 mIU/ml, and the rest, 46.7%, had an anti-HBs titer >100 mIU/ml, while 30% of them were not protective, 22.2% of them were males, and the rest, 77.8%, were females, with a mean age of 30 years. Conclusion: Though many HCWs had been exposed to the virus before or had received vaccinations, the majority of them were seroprotected against the hepatitis B virus. HCWs must be made aware of the prescribed immunization schedule and must be required to receive all recommended vaccinations.","PeriodicalId":478944,"journal":{"name":"Middle East Research Journal of Medical Sciences","volume":"44 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140510530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For exploring the potential role of aging in male infertility; we examined the semen quality in Northern Sudanese sub fertile men. Objectives: This study aimed to look into possible association between male age and different sperm parameters derived from semen analysis taking into account the World Health Organization (WHO) reference values of semen indicators. Methods: A retrospective descriptive study included 150 Northern Sudanese Couples men presenting with primary or secondary infertility who underwent semen analysis at Modern Specialized Laboratory (MSL), Atbara, River Nile State, Sudan, between August 2021 and April 2023. Seminal fluid were collected in a sterile, wide mouth container, by dry masturbation, after at least 48 hours of abstinence and brought immediately to the laboratory. Color, viscosity, PH and volume were examined macroscopically, and motility under the microscope within 20 minutes to one hour of collection time and was stained by10% Giemsa stain after fixation by spirit for 10-15min. Morphology and abnormal sperms were checked manually to assess the abnormalities in the head, midpiece and the tail of the sperm. This manual method was allowed the discrimination of immature sperm from white blood cells (WBCs) and then counting the WBCs. Data were collected by predesigned closed ended questionnaires, through direct personal interview with patients and questionnaires were filled after an informed consent was taken from each patient. The statistical analysis was done with the help of statistical software for social sciences SPSS 21. The characteristics of the semen, personal and demographic data were analyzed according to the standard protocols. Results: There was significant positive association between age and the different measured parameters except for the reaction and presence of microorganism and, a significant difference was found with the presence of microorganism by p=0.004.
