The increasing occurrence of wastewaters associated with industrial development has begotten a permanent search for new and more efficient techniques for the removal of hazardous substances such as heavy metals and dyes. The use of natural and available resources to develop improved and sustainable commodities for this purpose remains crucial and is among promising emerging green technologies for water treatment. It offers the gradual shifting of hazardous industrial chemicals precursors to the abundant non-metallic mineral resources that receive an added value. This work investigated the uptake capacity by the adsorption process of methylene blue (MB) and azocarmine G (AG) onto nano-silica synthesized from kaolinite clay. The effects of contact time (0-30 min), the adsorbent dosage (5-100 mg), the initial pH of the solution (1-11 for MB and 1-7 for AG), and the initial dye concentration (5-50 mg/L) were studied. The selected conditions to carry out kinetic and isotherm adsorption experiments were: 15 mins, 20 mg, 11 for MB, 1.01 for AG, and 50 mg/L. Four adsorption isotherms and three kinetic models were used to model the adsorption data thanks to linear and non-linear regression methods. From the obtained results, the Freundlich isotherm model fitted well the adsorption phenomenon while the pseudo-second-order kinetic model described well the adsorption mechanism. Furthermore, the free energy of adsorption was similar for the two absorbents, 0.71 kJ, pointing physisorption as the dominant adsorption mechanism. The optimum MB and AG uptake were respectively 13.8 and 36.1 mg/g. Conclusively, the nano-silica represents a potentially viable and powerful adsorbent whose use could lead to a plausible improvement in environmental preservation.

Background: Ovarian cancer (OC) is the fifth cause of cancer mortality in females. There were an estimated 300,000 new cases of OC diagnosed worldwide in 2018, corresponding to 3.4% of all cancer cases among women. The high mortality rate of OC attributed to asymptomatic growth of the tumor leads to its diagnosis at advanced stages. About 85% - 90% of OC are epithelial including serous, endometrioid, clear cell, and mucinous carcinoma. Aim: To study the immunohistochemical (IHC) expression of FOXA1 and p53 in epithelial OC and its association with prognostic indicators such as age, tumor size, stage, grade, and histological type.Materials and methods: The study included 52 cases with EOC from the pathology department, faculty of medicine, Aswan, and Sohag Universities, in the period from January 2017 to December 2019. This study involved 52 patients with OC and a median age of 53 years. Different histological types were included as 37 serous, 12 mucinous, 1 case endometroid 2 cases clear cell OC. The study cases were classified into 22 Grade I, 16 Grade II, and 20 Grade III. About 22 cases were at stage I, 9 at stage II, 11 at stage III, and 10 at stage IV. Tissue sections were stained using the IHC technique with FOX A1 at a dilution of 1:100 and p53 at 1:100. Results: A statistically significant correlation was found between FOX A1 expression and advanced patient's age, high grade, advanced stage, ruptured capsule, and ascites, regardless of tumor laterality. No significant association was found between p53 immunoexpression and the same clinic-pathological parameters although p53 was associated with serious type. Conclusion: FOXA1 immunoexpression in EOC is considered a poor prognostic factor in EOC. FOXA1 could be a potential therapeutic target and prognostic marker in EOC.

Median arcuate ligament syndrome is a rare entity. This clinical condition develops by compression of the root of a celiac artery with the median arcuate ligament. The typical triad of this syndrome is the following; abdominal discomfort and pain, especially after a meal, and weight loss. In diagnosis, other causes should be ruled out and compression must be demonstrated by any type of imaging method. The main principle of treatment is cutting down the median arcuate ligament. A 54-year-old woman presented with untreatable recurrent abdominal pain and was diagnosed with median arcuate ligament syndrome by imaging with angiographic computed tomography. This patient was operated on. We performed laparoscopic division of median arcuate ligament with the retrograde surgical dissection technique. The patient was discharged from the hospital without any complaint on the third day after surgery. She was still symptom-free after 12 months.The laparoscopic retrograde dissection approach is a safe and feasible treatment modality for median arcuate ligament syndrome.

An article by Baum, et al. “Unclear swelling in the region of a maxillary canine tooth” [1] caught our interest. A 14-year-old boy had developed an adenomatoid odontogenic tumor (AOT) without undergoing maxillofacial surgery. During an INTERPLAST-Germany mission [2] in Goma, Democratic Republic of Congo, we operated on a young man with an advanced odontogenic tumor. Since we are confronted with fist-sized odontogenic tumors (mostly ameloblastoma of the mandible) every time we operate in Africa, where they grow out of control due to a lack of experienced surgeons, it may be of interest to our colleagues in developed countries to know which grotesque tumors are prevented by early surgery.

The study has been undertaken to investigate the determination of digital financial fraud (cyber fraud) in Jamtara district of Jharkhand (the hub of cyber fraudsters) the basic tools & techniques which are used by the offenders and to find out the socio-economic condition of their social life & find the new challenging in cybercrime investigation and to find out the more secure way of digital financial flow, by using survey research method and work on secondary as well primary data which was related to this study, cybercrime especially financial fraud becomes the new challenging task for law enforcement agencies.Digital financial frauds are being within an undefined jurisdiction so it becomes more difficult to investigate the cases and due to other different public as well private sectors of service providers like the telecom companies and the banks are unable to make the defensive system for their customer also. This is the main reason for delays in cyber-related case investigation and a very low conviction rate in cyber-related cases.

Background: Iron deficiency anemia is common during pregnancy since the overall iron requirement is greater than non-pregnant women and is associated with adverse outcomes. Iron deficiency (ID) is a state of insufficient iron to maintain normal physiological functions of tissues and leads to anemia.Objectives: To assess factors associated with the utilization of Iron with Folic acid supplement Among Pregnant Women Attending Antenatal care at Government Health Facilities and Family Guidance Clinic in Hawassa City, South Ethiopia.Methods: Institutional-based cross-sectional study design was conducted among 412 health providers who are working at public health institutes in Hawassa city from March to April 2015. Pretested Self-administered questionnaires were used to collect the data. The data was entered into Epi-data and analysed by SPSS version 26.0. Bivariate and multivariate regression analysis was used to see the significant association between the outcome and independent variables. Odds ratios and 95% CI will be computed to measure the strength of the association, p - value of ˂ 0.05 will be considered a statistically significant.Results: A total of 412 pregnant women who came to attend ANC at least for the second time were interviewed in seven health facilities. Our study showed that 333 (81%, 95% CI: 77.2 - 84.8) pregnant women reported taking IFA supplements and high compliance was 37.7% (95% CI: 32.5 - 42.9). In multivariable analysis, side effects and low acceptance of the supplement were significantly associated with compliance to IFA supplementation (p < 0.05).Conclusion: There is a relatively better level of compliance towards IFA supplementation compared to other national data. Pregnant women should be counseled regarding how to manage the side effects of IFA supplements during ANC. Further research has to be done on the acceptability of the supplements.

Introduction: Fatigue is a common non-motor symptom of Idiopathic Parkinson’s Disease (IPD). The aim is to research the relationship between fatigue of IPD patients and the clinical findings, of mood disorders.Material and methods: A total of 39 patients with IPD were included in the study. The relationship between fatigue severity and demographic characteristics and the treatment was evaluated in IPD. The severity of fatigue was evaluated by Fatigue Severity Scale (FSS). Motor impairment was scored by the modified Hoehn and Yahr scale. The patients were assessed for the presence of depression and anxiety with the Hospital Anxiety and Depression Scale (HADS). Results: The mean age of the patients was 70.62 ± 8.35 years. 23 were men and 16 were women. The mean disease duration was 6.18 ± 3.35 years. The patients were assigned into two groups according to the presence of fatigue measured by FSS with less than 5 (Group I) and 5 or more (Group II). There were no statistically significant differences between the two groups with respect to mean age, mean age of onset, and mean disease duration of the patients (p > 0.05). There were no significant differences between the two groups for HADS depression, anxiety values, and terms of antiparkinsonian therapies (p > 0.05). The severity of fatigue was correlated with the HADS anxiety levels (p < 0.05).Discussion: Fatigue is an important non-motor symptom that is underestimated in clinical follow-up. We didn’t find any correlation between fatigue and age, duration of disease onset, or drug use. There was no significant correlation between the fatigue score and depression, and pain. However, the fatigue scores were higher in patients with high anxiety scores and females.

Background: Hyponatremia associated with COVID-19 is considered an independent risk factor for a prolonged hospital stay, intensive care admission, and death, but its causes and treatment are not yet well known. Many workers attribute hyponatremia associated with COVID-19 to acute kidney injury and nephropathy associated with the disease. Others suggest that it is related to the syndrome of inappropriate antidiuretic hormone secretion, sepsis, or hypothalamic-pituitary dysfunction. We report a case of persistent acute hyponatremia in a COVID-19 patient with multifactorial etiology. Case presentation: A managed 77 years with known hypertension, type II DM, ischemic heart disease, chronic kidney disease (stage 3B and on treatment) presented with post-COVID-19 pneumonia, confusion, fever, generalized fatigability, dizziness, and lower limb edema. COVID-19 ad has been diagnosed two weeks earlier with a positive nasopharyngeal swab and was managed with dexamethasone, 10 mg oral for 10 days, azithromycin, 500 mg once orally, and levofloxacin, 500 mg once orally. At presentation, laboratory investigation showed hyponatremia (127.7 mg/dl). Conclusion: The etiology of hyponatremia associated with COVID-19 is different from that in other cases of hyponatremia and its management should be individualized according to patient history and clinical assessment, and effort is needed to determine the exact cause.

Chronic Kidney Disease (CKD) by definition is a disease characterized by irreversible elimination of renal function, which keeps propagating as corroborated by an estimated glomerular filtration rate (eGFR) of < 60 ml/min/1.73m2, the constant existence of presentation which pointed to Kidney injury (proteinuria, active sediments of urine, histological injury, structural aberrations or prior history with regards to Kidney transplantation) or both that are persistent for greaterthan 3 mths [1].

Background: The novel coronavirus is a rapidly spreading respiratory disease that has been declared a pandemic by the World Health Organization (WHO) and a global public health emergency. The use of face masks has been recommended by the WHO and the Centers for Disease Control (CDC) as a standard prevention method for transmission of COVID-19.Objective: The objective of this study is to determine face mask utilization and associated factors in combating the COVID-19 pandemic among government employees in Akaki district administration offices in Akaki District, Oromia, Ethiopia, 2022Methods: A quantitative cross-sectional study was conducted from December 1, 2021, to February 15, 2022, on 385 government employees working in Akaki district administration offices. After obtaining consent from the study participants, data were collected using pretested, self-administered, and standardized questionnaires adapted from other studies. After the data was collected, it was entered into Epi info version 7.2.6, cleaned, and analyzed using SPSS version 26. A logistic regression model was computed to measure the association between the predictor and outcome variables. A p - value of.05 with a 95% CI was used as the cut-off point to declare the level of statistical significance. Results: The study showed that the magnitude of good practice for facemask utilization was 213 (53.5%) (95% CI: 1.50, 1.60) for preventing COVID-19. In the multivariate logistic regression analysis, the odds of using face masks among male employees (AOR = 0.275; 95% CI: 0.137, 0.555), employees aged 20-29 (AOR = 0.17; 95% CI: 0.065, 0.481 ), employees aged 30-39 (AOR = 0.260, 95% CI: 0.109, 0.623), employees of less than five family size (AOR = 0.549, 95% CI: 0.303, 0.995), work experience at 6-12 (AOR = 0, 32, 95 CI: 0.120, 0.450), poor knowledge about face mask use (AOR = 0.504, 95% CI: 0.302, 0.844), and employees with a negative attitude (AOR = 0.430, 95% CI: 0.256, 0.721) were factors significantly associated with face mask utilization.Conclusion: The magnitude of facemask utilization was low (53.5%) compared to other studies. The results of the study showed that age, sex, household family size, work experience, poor knowledge, and the negative attitude of employees toward facemask utilization were among the factors significantly associated with facemask utilization.
