The prevalence and associated factors for primary headache disorders in adolescents in eastern Sudan: a community-based cross-sectional study.

Background: Headache disorder is the second-highest cause of disability worldwide; however, data are scarce on headache among adolescents, especially in Africa. There has yet to be published data on headache among adolescents in Sudan, the third-largest country in Africa. This study aimed to assess the prevalence of primary headache disorders and associated factors among adolescents (10-19 years) in eastern Sudan. Methods: A community-based cross-sectional study was conducted in the city of Gadarif in eastern Sudan. Questionnaires were used to gather the adolescents' sociodemographic characteristics. Headache diagnostic questions were based on the beta version of the International Classification of Headache Disorders-III (ICHD-3). Multivariate analysis was conducted to assess the associated factors for primary headache disorders, and the results were expressed as risk ratios (RRs) and 95.0% confidence interval (CI). Results: Of the 401 enrolled adolescents, 186 (46.4%) and 215 (53.6%) were male and female, respectively. The median (IQR) age was 14.0 (12.1-16.2) years. Eighty-one (20.2%) of the 401 adolescents reported experiencing primary headache disorders, including migraine with aura in 16 (4.0%), migraine without aura in 33 (8.2%), tension-type in 14 (3.5%), and undifferentiated headache in 18 (4.5%) adolescents. The prevalence of primary headache disorders was significantly higher in females than in males [55/215 (67.9%) vs. 26/186 (32.1%), p = 0.004]. In the multivariate analysis, increased age (RR = 1.09, 95.0 CI = 1.02-1.16) and being female (RR = 1.75, 95.0 CI = 1.14-2.67) were associated with increased RR of primary headache disorders. Parents' education level and occupation, smoking/snuff use, and body mass index were not associated with primary headache disorders. Conclusion: One-fifth of the adolescents in eastern Sudan reported experiencing primary headache disorders, which was more common in females and with increased age.

Periconceptional folic acid usage and its associated factors in eastern Sudan: A cross-sectional study.

BACKGROUND: Several countries poorly adhere to the World Health Organization's recommendation of folic acid supplementation in the periconceptional period, especially in limited-resource settings. OBJECTIVE: The objective of this study was to investigate the prevalence of and the factors associated with folic acid usage in the periconceptional period among pregnant women at Gadarif Maternity Hospital in eastern Sudan. STUDY DESIGN: This is a cross-sectional study. METHODS: This study was conducted in eastern Sudan from April to September 2022. A total of 720 pregnant women in their first trimester were enrolled. The sociodemographic characteristics and clinical and obstetrical data of pregnant women in their first trimester were assessed using a face-to-face questionnaire. In addition, multivariate regression analysis was performed. RESULTS: In this study, the median (interquartile range) of the age and gravidity of the enrolled women was 26.3 (24.14-29.52) years and 2 (1-4), respectively. Of these 720 women, 423 (58.8%) used folic acid during the periconceptional period, while 27 (3.7%) women used folic acid in the preconceptional period. None of the investigated factors (age, residence, education, employment, body mass index, or gravidity) were associated with periconceptional use of folic acid. CONCLUSION: The study revealed a low prevalence of folic acid usage in preconceptional period among pregnant women in eastern Sudan. Additional efforts are needed to promote folic acid usage in the preconceptional period as well as in the first trimester.

Prevalence and associated factors of stunting and thinness among adolescent Sudanese schoolchildren: a cross-sectional study.

BACKGROUND: Malnutrition among adolescents is a considerable health problem worldwide. There are scarce data on undernutrition among adolescents in Sudan. METHODS: A cross­sectional study was conducted to investigate the prevalence and associated factors of stunting and thinness among adolescent schoolchildren in northern Sudan. The questionnaires were used to collect information on sociodemographics. Weights and heights were measured and the height-for-age and body mass index-for-age cut-offs recommended by the WHO were applied, followed by logistic regression analysis. RESULTS: Of 384 enrolled adolescents, 202 (52.6%) were females and 182 (47.4%) were males. The median (IQR) age of these adolescents was 15.1 (14.0‒16.3) y. Seventy-six (19.8%) and 52 (15.4%) adolescents had stunting and thinness, respectively, and 15 (3.9%) had both stunting and thinness. Multivariate analysis showed that increased age (adjusted OR [AOR]=1.30, 95% CI 1.08 to 1.57) and male gender (AOR=5.82, 95% CI 3.11 to 10.91) were associated with stunting. Male gender (AOR=2.08, 95% CI 1.14 to 3.82) and smoking/tobacco snuff (AOR=2.61, 95% CI 1.07 to 6.36) were associated with thinness. CONCLUSIONS: The findings of the current study are that both stunting and thinness are important health problems, especially among boys, older participants and smokers.

Red Cell Distribution Width and Prediabetes in Adults in Northern Sudan: A Case-Control Study.

Diabetes mellitus (DM) is a major public health issue worldwide. Red cell distribution width (RDW) has been reported to have predictive value in several diseases, including DM. Few data exist on the association between RDW and the prediabetic stage. Thus, the present study aimed to investigate the association between RDW and prediabetes in adults in Sudan. This case-control study was conducted in Northern Sudan in 2022. The cases (n = 107) were prediabetic patients categorized according to the level of glycated hemoglobin (HbA1c), which ranged from 5.7% to 6.4%, while the controls (n = 107) were healthy participants. A questionnaire was used to collect the data. Standard methods were used to measure the HbAIc level and RDW. Logistic regression analysis was performed. The median (interquartile range (IQR)) of the RDW was significantly higher in prediabetic patients than in the controls (14.5% [13.8-15.3%] vs. 14.1% [13.6-14.7%], p = 0.003). Sex, educational level, occupational status, marital status, cigarette smoking, alcohol consumption, family history of DM, and body mass index were not associated with prediabetes. In the multivariate-adjusted model, higher age and higher RDW were associated with prediabetes. A positive correlation was found between RDW and HbA1c levels (r = 0.19, p = 0.006). In conclusion, this study supports the use of RDW as a predictor of DM.

Iron deficiency and thyroid dysfunction among sudanese women in first trimester of pregnancy: a cross-sectional study.

BACKGROUND: Pregnant women are more susceptible to iron deficiency (ID), and it can lead to several maternal and perinatal adverse effects. There are some published data on the effect of ID on thyroid function, but none of the studies were conducted in sub-Saharan African countries including Sudan. This study was conducted to investigate association between ID (ferritin < 15 µg/L) and thyroid functions [thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4)] among Sudanese women in the first trimester of pregnancy. METHOD: A cross-sectional study was conducted in Saad Abuelela Maternity Hospital, Sudan. Obstetric/sociodemographic characteristics were gathered through questionnaires. Hemoglobin, serum ferritin, TSH, FT3, and FT4 were measured in all pregnant women. Continuous variables were compared with either independent sample t-test if they were normally distributed, or with Mann-Whitney U- test if they were not-normally distributed. Spearman correlations were performed between the continuous variables. RESULTS: In total, 127 pregnant women with mean [standard deviation (SD)] age of 27.0 (5.5) years and gestational age of 10.5 (3.0) weeks, respectively, were enrolled in this study. Forty-seven (37.0%) of these 127 women had ID. While the median [interquartile range (IQR)] of the parity, TSH, and FT3 were not different between women with ID and women without ID, the median (IQR) of FT4 was significantly lower in women with ID compared with women without ID [1.020 (0.910‒1.120) vs. 1.095 (0.990‒1.217) pmol, P = 0.014]. Serum ferritin was inversely correlated with FT3, (r = -0.225, P = 0.011). There was no significant correlation between serum ferritin, TSH, and FT4. CONCLUSIONS: Iron deficiency was common during the first trimester of pregnancy and was associated with thyroid dysfunctions. Therefore, ID should be evaluated to avoid thyroid dysfunction.

Gene polymorphisms of cyclin-dependent kinase inhibitor and matrix metalloproteinase-9 in Sudanese patients with esophageal squamous cell carcinoma.

BACKGROUND: The polymorphisms of the cyclin-dependent kinase inhibitor (CDKN1A) gene and matrix metalloproteinase-9 (MMP9) gene may increase one's susceptibility to malignancies. In this study, the association of the single nucleotide polymorphisms (SNPs) CDKN1A rs1059234 c.70C>T at the 3' untranslated region and MMP9 rs17576 (c.836A>G, p.Gln279Arg) with esophageal squamous cell carcinoma (ESCC) in Sudanese individuals were investigated. MATERIALS AND METHODS: A case-control study involving age- and gender-matched groups were conducted in a cancer center in eastern Sudan (Gadarif) between April and October 2020. The case group consisted of ESCC patients, whereas the control group comprised healthy subjects. Polymerase chain reaction-restriction fragment length polymorphism was performed for the genotyping of the CDKN1A rs1059234 and MMP9 rs17576 SNPs. The genotyping results were confirmed by Sanger sequencing. RESULTS: The genotype distributions for CDKN1A rs1059234 and MMP9 rs17576 were in agreement with the Hardy-Weinberg equilibrium. The variant allele T in CDKN1 rs1059234 c.70C>T was significantly more prevalent in the ESCC patients than in the healthy controls [51.3% vs. 19.2%; OR = 4.4; 95% CI (2.6-7.4); p < 0.001]. Moreover, in CDKN1A rs1059234, the genotype TC + TT [76.9% vs. 38.4%; OR = 5.3; 95% CI (2.6-10.7); p < 0.001] was more frequent in the cases than in the controls, and it was significantly associated with ESCC risk. In MMP9 rs17576, the variant allele G was also significantly prevalent in the cases relative to the controls, and it was significantly associated with increased ESCC risk in the cases compared with the controls [27.5% vs. 1.9%; OR = 19.4; 95%CI (5.8-64.1); p < 0.001]. Both genotypes containing the allele G (AG + GG) were the most common genotypes in the cases [48.7% vs. 3.8%; OR = 23.7; 95%CI (6.8-81.7); p < 0.001], and they significantly increased the risk of ESCC. CONCLUSION: A significant increase in ESCC risk is associated with the SNPs CDKN1A rs1059234 and MMP9 rs17576.

The prevalence and associated predictors for Bethesda III-VI for reporting thyroid cytopathology in Royal Commission Hospital, Kingdom of Saudi Arabia.

Background: Thyroid cancer is increasing globally and is currently the most prevalent endocrine malignancy. Recent data show an increase in the incidence of thyroid cancer in the Kingdom of Saudi Arabia (KSA). Thyroid ultrasound and fine-needle aspiration cytology (FNAC) are the cornerstones in managing thyroid nodules. We conducted this study to evaluate the prevalence and the associated predictors for thyroid nodule Bethesda III-VI in eastern KSA. Methods: A retrospective study was conducted between January 2015 and 31 August 2021. The participants were recruited patients who received a thyroid ultrasound and ultrasound-guided thyroid FNAC, using the thyroid imaging reporting and data system (TI-RADS) and the Bethesda Classification, respectively. Result: Three hundred and ten patients who underwent thyroid FNAC were enrolled in the study. The median (interquartile, IQR) age was 47.0 (20.0) years, and 266 (85.8%) of them were females. The median (IQR) body mass index was 30.2 (7.6) kg/m2. Out of these participants, 64.8% were euthyroid, 27.4% had hypothyroidism and 7.7% had hyperthyroidism. The ACR TI-RADS-3, 4 and 5 were 51.3%, 46.1% and 2.6%, respectively. The Bethesda outcome of thyroid FNAC I-VI was 5.2%, 63.9%, 15.5%, 5.8%, 3.5% and 6.1%, respectively. The risk for malignancy (Bethesda III-VI) was documented in 31.0% and atypia of undetermined significance was most prevalent (15.5%). A higher ACR TI-RADS score was associated with a higher risk of malignancy: ACR TI-RADS-3 (20.8%), ACR TI-RADS-4 (39.2%) and ACR TI-RADS-5 (87.5%). In a multivariate analysis, only the ACR TI-RADS score was significantly associated with the outcome of thyroid FNAC: ACR TI-RADS-4 [OR = 2.59 (95% CI = 1.54-4.36)] and ACR TI-RADS-5 [OR = 29.03 (95% CI = 3.44-245.07)]. Conclusion: There was a high prevalence of Bethesda III-VI and atypia of undetermined significance was most prevalent. A thyroid ultrasound report for TI-RADS was significantly associated with the outcome of thyroid FNAC and is a reliable tool in the absence of molecular testing for thyroid cancer.

Pattern and Trends in Adult Hospitalization/Admission and Mortality Among Medical Ward Inpatients at Gadarif Hospital in Eastern Sudan: A Four-Year Retrospective Study.

Purpose: Sub-Saharan Africa suffers from a dual impact of communicable (CDs) and non-communicable diseases (NCDs). There is scarce data on causes, trends of admission, and deaths among patients in Sudan. We aimed to determine the causes, trends of admission, and mortality among adult patients admitted to Gadarif Hospital in Eastern Sudan. Patients and Methods: The medical records of adult patients admitted to Gadarif medical wards from January 2017 to December 2020 were reviewed for age, gender, causes of admission, and outcomes. Multivariate Cox regression analysis was used to analysis factors (age, sex, years, and disease) associated with the mortality. Results: Of the 7230 patients who were admitted, 2221 (34.7%) were females and 5009 (69.3%) were males. The median age (interquartile range, IQR) was 47.0 (35.0) years. Of these 7230 patients, 3167 (43.8%) and 4063 (56.2%) patients were admitted with CDs and NCDs, respectively. Cardiovascular diseases (18.4%), snakebites (12.9%), and visceral leishmaniasis (12.0%) were the most common causes of admission. The overall in-patient adult deaths were 674 (9.3%). Cardiovascular diseases (22.3%), neurological diseases (16.9%), sepsis (15.9%), renal diseases (13.9%), and snakebites (8.3%) were the most common causes of inpatient mortality. Malignancy (20.7%), sepsis (20.9%), neurological diseases (17.4%), and cardiovascular diseases (13.8%) comprised the highest case fatality rates among the admitted patients. Using a Cox regression model (adjusted), age (adjusted hazard ratio = 1.02, 95% confidence interval = 1.01‒1.03) was associated with increased mortality hazard. However, the gender and years of admission were not associated with increased mortality hazard. Conclusion: Admissions and mortality rates for CDs and NCDs are high compared with other African countries. Preventive measures are required to avert the high burden of these diseases. Health care systems in Sudan need to be prepared to deal with the dual burden of the diseases.

The prevalence and phenotypic manifestations of polycystic ovary syndrome (PCOS) among infertile Sudanese women: a cross-sectional study.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a global health problem associated with significant morbidity during reproductive age. Only a few published studies that address the clinical manifestations and phenotypic presentation of the disease have been conducted in Africa, including Sudan. Thus, this study aimed to evaluate the clinical and biochemical presentation of the different PCOS phenotypes among infertile Sudanese women. METHODS: A cross-sectional, descriptive study was conducted from January to December 2019. A total of 368 infertile women with PCOS (based on the Rotterdam criteria) were recruited from a fertility center in Khartoum, Sudan. Clinical, hormonal, and ultrasonographic characteristics were described and compared between the four phenotypes of PCOS. RESULTS: Majority (321 [87.2%]) of the women had oligo/anovulation (OA). Polycystic ovary morphology on ultrasound appeared in 236 (64.1%) women, acne in 171 (46.5%) women, acanthosis nigricans in 81 (22.0%) women, and hirsutism in 101 (27.4%) women. Phenotype D was the most prevalent among infertile Sudanese women (51.6%), followed by phenotype B (22.6%), phenotype C (18.2%), and phenotype A (7.6%). No statistical differences in the body mass index and hormonal profile between the four phenotypes were noted. Women with phenotype A were older and had high mean blood pressure, and a higher waist/hip ratio was observed among women with phenotype D. CONCLUSION: Unlike the global distribution of PCOS phenotypes, Sudanese women uniquely expressed phenotype D as the most prevalent. More epidemiological studies are needed in the region due to geographical, ethnic, and genetic variations.

Polycystic ovary syndrome (PCOS) is a global health problem associated with significant drawbacks during reproductive life. Few published studies have been conducted in Africa (including Sudan) addressing the clinical manifestations and phenotypic presentation of the disease. Therefore, we aimed to evaluate the clinical and biochemical presentation of the different PCOS phenotypes among infertile Sudanese women. A total of 368 infertile women with PCOS from a fertility center in Khartoum, Sudan, participated in the study. Clinical, hormonal, and ultrasonographic characteristics were described and compared between the four phenotype groups of PCOS. In this regard, Sudanese women uniquely expressed phenotype D as the most prevalent, and this does not match with the global distribution of PCOS phenotypes. Moreover, women with phenotype A were older and had high mean blood pressure, and a higher waist/hip ratio was observed among women with phenotype D. More epidemiological studies on this subject are needed in the region due to geographical, ethnic, and genetic variations.

Misconceptions and traditional practices toward infant teething symptoms among mothers in eastern Sudan: a cross-sectional study

There is no much published data on the mothers' false beliefs about signs and symptoms associated with teething in Sudan. Aim: This cross-sectional hospital-based study was conducted to assess mothers` knowledge about infant teething process and to evaluate mothers' practices used to alleviate teething disturbances in Gadarif city, eastern Sudan. Methods: Questionnaires were used to collect data. Multivariate logistics regression models were performed and adjusted odds ratios (AOR) and 95% confidence intervals (CI) were calculated. Results/Conclusion: Of a total of 384 participating mothers, 126 (32.8%) had good knowledge about infant teething. The mothers' knowledge was associated with a higher number of children in the family (adjusted odds ratio [AOR] = 1.14) and with having a job (AOR = 2.22). Mothers residing in rural areas (AOR = 0.40) and mothers with lower than secondary education (AOR = 0.43) were less likely to have good knowledge about teething. Diarrhea (88.5%), fever (86.5%), an urge to bite (76.6%), and poor appetite (71.9%) were the signs and symptoms most attributed to teething by mothers. Only the mother's knowledge about teething was associated with reporting fever as a sign. A considerable number (317; 82.6%) of mothers reported performing "Dokhan" (acacia wood smoke), 313 (81.5%) preferred to administer paracetamol or other systemic analgesics, 262 (68.2%) agreed that a child with tooth eruption should be taken to a hospital or health center, and 216 (56.3%) believed that antibiotics relieved symptoms related to teething

High Mortality Rate in Adult COVID-19 Inpatients in Eastern Sudan: A Retrospective Study.

AIM: The current pandemic of coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory coronavirus syndrome 2 (SARS-CoV-2). It is a global public health concern that has resulted in the rapid growth in the number of infected patients with significant mortality rates. Hence, we conducted a retrospective study in Gadarif Hospital to evaluate the presenting manifestations, mortality rate, and the risk factors associated with mortality in hospitalized patients. METHODS: A retrospective study was conducted at Gadarif Hospital in Eastern Sudan. Medical files of the patients admitted during the period between April and July 2020 were reviewed. All the files of the adult patients (aged 18 or above), of both sexes, who had a confirmed COVID-19-positive status via laboratory testing using PCR and who were admitted during this period were reviewed. The data extracted included patients' demographics and initial clinical presentation, symptoms, signs, and the laboratory and radiographic findings. The data were analyzed using SPSS v22. RESULTS: Eighty-eight patients were admitted with COVID-19. The median (interquartile) age was 62 (55.00-70.00) years old, and 72 (81.8%) of them were males. Most patients (75%) experienced a one-week duration of symptoms. A fever (87.5%), cough (80.68%), and shortness of breath (77.27%) were the most common presenting symptoms. Following a clinical assessment, both the systolic and diastolic blood pressure were found to be normal in most patients, at 92.05% and 89.77%, respectively. An oxygen saturation of less than 90% was seen in 71.59% of patients. The general mortality rate was 37.5% and most deaths occurred during the first 24 h of admission (21/33 [63.64%]). There was no significant difference in the death rate between females and males (5/16 [31.3%] vs 28/72 [38.9%], P = 0.776). There was no significant difference in the body mass index, tobacco use, or education level between the patients who died and those who survived. A logistic regression showed that being older (AOR = 1.05, 95% CI = [1.01, 1.10]) and having a lower PO2 level (AOR = 1.11, 95% CI = [1.04, 1.16]) were associated with mortality. CONCLUSION: The general mortality rate was 37.5%, and the risk factors that could predict increased mortality in hospitalized COVID-19 positive cases included old age and a lower PO2 level.

Peripheral hematological parameters in women with polycystic ovary syndrome.

OBJECTIVE: There have been few studies on hematological parameters (e.g., hemoglobin, red cell distribution width, white blood cells, and mean platelet volume), and polycystic ovary syndrome (PCOS). This study aimed to compare hematological parameters between women with PCOS and controls. METHODS: We performed an age-matched case-control study in Faisal bin Mishal Center for Infertility, Buraidah (Kingdom of Saudi Arabia). The cases were women with PCOS and an equal number of healthy women were enrolled as controls. The basic gynecological history was recorded and blood samples were analyzed for blood parameters using an automated hematology analyzer. RESULTS: The two groups (60 women in each arm of the study) were similar in age. However, body mass index was significantly higher in women with PCOs compared with controls. There were no significant differences in any of the hematological parameters (hemoglobin, red blood cells, red cell distribution width, white blood cells, platelets, and mean platelet volume) between the two groups. CONCLUSION: There does not appear to be a significant difference in hematological parameters in Saudi women with PCOS and healthy controls. A larger study on this issue is required in the future.

Prevalence and associated factors of hypertension among adults in Gadarif in eastern Sudan: a community-based study.

BACKGROUND: Hypertension is becoming an increasingly common health issue worldwide, especially in countries in Sub-Saharan Africa. Hypertension is the leading risk factor for premature death and disability worldwide, and it is the leading risk factor for mortality from cardiovascular diseases worldwide. The data on hypertension in Sudan that has been published is limited. We conducted this study to assess the prevalence of hypertension and its associated risk factors. METHODS: A multistage sampling survey was conducted in Gadarif, Eastern Sudan, from January to May 2018 to investigate the prevalence of hypertension and associated factors in adults in Eastern Sudan. The World Health Organization (WHO) three-level stepwise approach questionnaire was used to gather sociodemographic characteristics (age, sex, height, weight marital status, education level, smoking habit, alcohol consumption habit, and family history of hypertension). Hypertension was defined as the presence of an average blood pressure of ≥140/90 mmHg or the reported use of anti-hypertensive medications for high blood pressure. RESULTS: A total of 600 participants (mean age: 44.9 years) were enrolled in this study. Four hundred twenty-two (70.3%) participants were women, and 196 (32.7%) participants were obese. Of the 600 enrolled participants, 245 (40.8%) individuals had hypertension, 44 (7.3%) had been previously diagnosed with hypertension, and 201 (33.5%) were newly diagnosed with hypertension. A logistic regression analysis showed no significant associations across the education level, marital status, overweight and hypertension factors. However, an older age (adjusted OR = 3.20, 95% CI = 2.28-4.51, P < 0.001) and obesity (adjusted OR = 2.41, 95% CI = 1.57-3.69, P < 0.001) were associated with the presence of hypertension. CONCLUSION: There is a high rate of hypertension in Eastern Sudan, especially among older and obese individuals. Preventive measures, such as dietary measures, should be implemented.

Association of VEGFA and IL1ß gene polymorphisms with preeclampsia in Sudanese women.

BACKGROUND: Preeclampsia can lead to adverse maternal and perinatal outcomes. There are few studies on the genetic factors associated with preeclampsia in Africa in general and in Sudan in specific. METHODS: A case-control study (60 women in each arm) was conducted at Saad Abualila Hospital in Khartoum, Sudan, from March to September 2018. The participants were genotyped for vascular endothelial growth factor A (VEGFA) rs3025039, interleukin 1 beta (IL1ß) rs16944, and IL1ß rs1143634 by performing polymerase chain reaction-restriction fragment length polymorphism analysis, and the results were confirmed by DNA sequencing. RESULTS: There was no significant difference in the age, parity, body mass index, or other characteristics tested between the preeclampsia group and the control group (60 women in each arm). The rs3025039, rs16944, and rs1143634 genotypes were distributed in accordance with Hardy-Weinberg equilibrium (p > .05). For rs3025039, CT, CT+TT, and the T allele were risk factors for preeclampsia (odds ratio [OR] = 2.4; 95% CI [1.12-5.32]; p = .02; OR = 2.49 [1.17-25.27]; p = .01; OR = 2.05; 95% CI [1.10-3.83]; p = .02, respectively). Regarding rs16944, only the heterozygous genotype CT was associated with preeclampsia (OR = 2.55; 95% CI [1.15-5.56]; p = .01). Regarding rs1143634, CT, CT+TT, and the T allele were risk factors for preeclampsia (OR = 5.28; 95% CI [2.26-12.33]; p < .001; OR = 4.50; 95% CI [2.06-9.81]; p < .001; OR = 2.75; 95% CI [1.48-5.12]; p = .001, respectively). CONCLUSION: Polymorphisms in IL1ß and VEGFA were associated with preeclampsia in this setting. Significant associations were observed between preeclampsia and rs3025039, rs16944, and rs1143634.

Placental growth factor, vascular endothelial growth factor, and hypoxia-inducible factor-1α in the placentas of women with pre-eclampsia.

BACKGROUND: Although the exact mechanism of pre-eclampsia - high blood pressure and proteinuria after 20 gestational weeks - is not yet fully understood, placental growth factor (PLGF), vascular endothelial growth factor (VEGF), and hypoxia-inducible factor (HIF) are known to play important roles in vascularization and in the pathology of pre-eclampsia. METHODS: PLGF, VEGF, and HIF-1α were evaluated by immunohistochemistry in the placentas of Sudanese women with mild or severe pre-eclampsia, and in normal controls. RESULTS: Sixty-two women had severe pre-eclampsia, 102 had mild pre-eclampsia and 101 women served as healthy controls. Immunohistochemical staining of PLGF was significantly lower in placentas of women with severe pre-eclampsia (16%) compared with those with mild pre-eclampsia (8.8%) and placentas of normotensive women (40.6%; p < .001). Significantly more of the pre-eclamptic placentas expressed VEGF: in 32%, 17.6%, and 14.9% (p = .020) of the placentas of women with severe or mild pre-eclampsia and in controls, respectively. Significantly more of the pre-eclamptic placentas expressed HIF-1α: in 15%, 10.8%, and 5.0% of the placentas of women with severe or mild pre-eclampsia, and in controls, respectively (p = .044). CONCLUSION: The current study showed that PLGF, VEGF, and HIF-1α are involved in the pathophysiology of pre-eclampsia.

Are there paternal components in human milk?

Breastfeeding is indeed the foundation for life and gives growing children a once-in-a-lifetime opportunity to grow and develop to their full potential. There are considerable studies on the role of maternal contribution to human milk components. It would be very important and interesting to explore the existence of a paternal contribution into the composition of human milk. Proceeding on this track, there is an abundant evidence that supports the hypothesis of paternal contribution in human milk composition. This evidence could be strengthened by the fact that a small population of the fetal cells migrate during pregnancy and stay for long time in the maternal body. This phenomenon is known as microchimerism. It has been well documented that some of these cells are of mature immunological and hematopoietic stem cells character. As the fetal parts contain 50% from each parent, any fetal parts in the maternal body (i.e., fetal microchimerism) should contain paternal components as well. The paternal genetic material is more responsible for the determination of the fetal sex (female XX or male XY). The variations in maternal human milk component that was clearly understood as related to child sex will substantially provide a solid basis for the investigation of the new hypothesis. In this short report, we conclude by briefly foregrounding the proposed role for paternal contribution on human milk composition for consideration and suggesting new directions for future research that would shed light on this subject.

The prevalence of serum magnesium and iron deficiency anaemia among Sudanese women in early pregnancy: a cross-sectional study.

Background: Anaemia during pregnancy is associated with adverse maternal and child health. Investigations of anaemia and its predictors among pregnant women are needed for preventive measures. Methods: A cross-sectional study was conducted to investigate the prevalence and determinants of anaemia in early pregnancy in Khartoum, Sudan. Clinical characteristics were gathered using a questionnaire. Serum ferritin, magnesium and high-sensitivity C-reactive protein (hs-CRP) were measured using different laboratory methods. Results: Of the 180 women in the study, 65.0% had anaemia (haemoglobin [Hb] <11 g/dl), 0.6% had severe anaemia (Hb <7 g/dl), 38.9% had iron deficiency (serum ferritin <15 µg/l), 30.6% had iron deficiency anaemia (<11 g/dl and serum ferritin <15 µg/l) and 57.2% had magnesium deficiency (<1.80 mg/dl). There was no significant difference in the age, parity, gestational age, body mass index (BMI) and hs-CRP between anaemic and non-anaemic pregnant women. Anaemic pregnant women had significantly lower levels of serum ferritin and serum magnesium. While age, parity, gestational age, BMI and hs-CRP were not associated with anaemia, low serum ferritin (odds ratio [OR] 0.97 [95% confidence interval {CI} 0.96 to 0.99]) and low serum magnesium (OR 0.91 [95% CI 0.84 to 0.99]) were associated with anaemia. There were significant positive correlations between Hb and serum ferritin (r=0.382, p<0.001) and serum magnesium (r=0.192, p=0.010). Conclusion: The role of magnesium as a possible contributing factor to anaemia in pregnancy has important implications for prevention and treatment of these women.

Higher Rate of Iron Deficiency in Obese Pregnant Sudanese Women.

AIM: To assess the association between obesity and iron deficiency (ID). MATERIAL AND METHODS: Pregnant women were recruited from Saad Abualila Hospital, Khartoum, Sudan, during January-April 2015. Medical history (age, parity, gestational age) was gathered using questionnaire. Weight and height were measured, and body mass index (BMI) was calculated. Women were sub-grouped based on BMI into underweight (< 18.5 kg/m^2), normal weight (18.5-24.9 kg/m^2), overweight (25-29.9 kg/m^2) and obese (≥ 30 kg/m^2). Serum ferritin and red blood indices were measured in all studied women. RESULTS: Two (0.5%), 126 (29.8%), 224 (53.0%) and 71 (16.8%) out of the 423 women were underweight, normal weight, overweight and obese, respectively. Anemia (Hb <11 g/dl), ID (ferritin <15µg/l) and iron deficiency anemia (IDA) were prevalent in 57.7%, 21.3% and 12.1%, respectively. Compared with the women with normal BMI, significantly fewer obese women were anemic [25 (35.2%) vs. 108 (85.7%), P < 0.001] and significantly higher number of obese women [25 (35.2) vs. 22 (17.5, P = 0.015] had iron deficiency. Linear regression analysis demonstrated a significant negative association between serum ferritin and BMI (- 0.010 µg/, P= 0.006). CONCLUSION: It is evident from the current findings that prevalence of anaemia and ID showed different trends about BMI of pregnant women.

Human papillomaviruses-related cancers. Presence and prevention strategies in the Middle east and north African regions.

Human papillomavirus (HPV) infections are estimated to be the most common sexually transmitted infections worldwide. Meanwhile, it is well established that infection by high-risk HPVs is considered the major cause of cervical cancer since more than 96% of these cancers are positive for high-risk HPVs, especially types 16 and 18. Moreover, during the last 2 decades, numerous studies pointed-out the possible involvement of high-risk HPV in several human carcinomas including head and neck, colorectal and breast cancers. The association between high-risk HPVs and cervical cancer and potentially other human malignancies would necessitate the introduction of vaccines which were generated against the 2 most frequent high-risk HPVs (types 16 and 18) worldwide, including the Middle East (ME) as well as North African countries. The presence of high-risk HPVs in the pathogenesis of human cancers in the ME, which is essential in order to evaluate the importance of vaccination against HPVs, has not been fully investigated yet. In this review, we present an overview of the existing epidemiological evidence regarding the presence of HPV in human cancers in the ME and the potential impact of vaccination against HPV infections and its outcome on human health in this region.
