Choriocarcinoma is a rare and aggressive form of gestational trophoblastic disease with a high potential for metastasis. We report the case of a 31-year-old female who presented with severe headaches, left-sided weakness, and speech difficulties. Her past medical history included a molar pregnancy, and she had elevated β-hCG levels of 200,000 mIU/mL. Imaging revealed a right frontoparietal hemorrhagic venous infarct and multiple lung metastases. Based on these findings and the patient's clinical history, a diagnosis of gestational choriocarcinoma with multiple metastases was confirmed. This case highlights the importance of considering choriocarcinoma in the differential diagnosis of young women presenting with neurological symptoms and a history of gestational trophoblastic disease. Early recognition and prompt treatment are crucial to improving outcomes in such cases.

Multiple system atrophy is a rare and quickly progressing neurological condition characterized by autonomic failure, parkinsonism, or cerebellar ataxia. It is classified into two subtypes: MSA with predominant parkinsonism (MSA-P) and MSA with predominant cerebellar ataxia (MSA-C). We are presenting here a 54-year-old male with parkinsonism, ataxia, and dysarthria. He was diagnosed with parkinson disease and was given a maximum dose of levodopa but has not responded. After a close neurological evaluation with magnetic resonance imaging of the brain, which shows atrophy of the cerebellum and a brainstem with a hot cross bun sign of the pons, suggestive of multiple system atrophy, he was diagnosed with multiple system atrophy cerebellar type, which is the first time to have this diagnosis in Somalia, which is a low-resource country.

Abstract Background Disparities in vaccination coverage exist in Somalia with Internally Displaced Persons (IDPs) being among the groups with the lowest coverage. We implemented an adapted Participatory Learning and Action (PLA) intervention, which focused on routine vaccinations among displaced populations living in Mogadishu IDP camps. The intervention was successful in improving maternal knowledge and vaccination coverage but unsuccessful in improving timely vaccination. We conducted a qualitative study to understand this result and analyze the multi-level barriers to routine childhood immunization uptake. Method In this qualitative study we used observation data from 40 PLA group discussions with female caregivers and purposively sampled nine vaccination service providers and six policy makers for interview. We also reviewed national-level vaccine policy documents and assessed the quality of health facilities in the study area. We used the socioecological framework to structure our analysis and analyzed the data in NVivo. Results The barriers to childhood vaccination among IDPs at the individual level were fear due to lack of knowledge, mistrust of vaccines, concerns about side effects and misinformation; opportunity costs; and costs of transportation. At the interpersonal level, family members played an important role as did the extent of decision-making autonomy. Community factors such as cultural practices, gender roles, and household evictions influenced vaccination. Organizational issues at health facilities such as waiting times, vaccine stock-outs, distance to the facility, language differences, and hesitancy of health workers to open multi-dose vials affected vaccination. At the policy level, confusion about the eligible age for routine vaccination and age restrictions for catch-up vaccination and certain antigens such as BCG were important barriers. Conclusion Complex and interrelated factors affect childhood vaccination uptake among IDPs in Somalia. Interventions that address multiple barriers simultaneously will have the greatest impact given the complex nature of vulnerabilities in this population. There is a need to strengthen the health system and connect it with existing community structures to increase demand for services. Our research highlights the importance of formative research before implementing interventions. Further research on the integration of health service strengthening with PLA to improve childhood vaccination among IDPs is recommended. Trial registration number ISRCTN-83,172,390.

Aim: After the outbreak of Coronavirus Disease 2019 (COVID-19), new headaches have been reported to develop or worsen among healthcare workers who regularly wear personal protective equipments. In this study, we investigated the possible relationship between de-novo (new-onset) headache features associated with the mask used and pre-existing and exacerbated headaches. It is the first study on this subject on behalf of Somalia. Methods: This is a cross-sectional study conducted at the Mogadishu COVID-19 pandemic hospital, Somalia, with volunteer healthcare workers. Data were collected through a questionnaire. Participants were asked 15 questions in the survey and Pearson-chi-square test was used as statistics. Results: This study was conducted with 200 healthcare workers working in the hospital, 114 (57%) were male, 86 (43%) were female, and the mean age was 28. Participants 90 (45%) used surgical masks, 32 (16%) filtered masks (N95), 78 (39%) both; majority of 109 (54.5%) wore masks for more than 6 hours a day. Pre-existing headache was reported by78(39%) of the subjects. 55(70%) of those with pre-existing headache reported aggravation of their headache. Statistically significant relationship was found between duration of mask use and aggravation of pre-existing headache. De-novo headache characteristics were throbbing 21(20%), pressing 31(29%), unilateral 19(18%), and 35(33%) bilateral. A statistically significant relationship was also found between the duration of use of face mask and the development of de-novo headache, regardless of mask type. Conclusion: As per our study, prolonged use of face masks during COVID-19 pandemics was associated with de-novo headaches and exacerbation of pre-existing headache. This situation, which has caused complaints as healthcare professionals and some patients continue to wear masks, will continue to be investigated.

A spontaneous coronary artery dissection (SCAD) is a tear that forms in a blood vessel in the heart without any obvious underlying etiology. It could be a single vessel or multiple vessels. We present a 48-year-old male known to be a heavy smoker without any chronic diseases or family history of heart disease who presents to the cardiology outpatient clinic with shortness of breath and chest pain on exertion. Electrocardiography demonstrated ST depression with T wave inversion of anterior leads, while echocardiography of the patient showed left ventricular systolic dysfunction with severe mitral regurgitation and mildly dilated left chambers. Based on his risks for coronary artery disease, his electrocardiography, and echocardiography, the patient was referred for elective coronary angiography to exclude the possibility of coronary artery disease. The angiography was done with the result of multivessel spontaneous coronary artery dissections involving the left anterior descending artery (LAD) and circumflex artery (CX) with a normal dominant right coronary artery (RCA). Due to the multi-vessel involvement of the dissection and the high risk of extension of the dissection, we preferred conservative management, including smoking cessation and heart failure management. The patient is doing well with regular heart failure treatment in cardiology follow-up.

Key Clinical Message Bilateral thalamic infarction in paramedian artery territory may present with severe acute illness, confusion, coma and memory impairment. However, subtle clinical presentation as in our case should alert the clinician to consider such a diagnosis as it can be associated with good prognosis. Abstract Bilateral thalamic infarct is a rare form of stroke. Mostly thalamic infarcts are unilateral. In most cases, bilateral thalamic infarction leads to cognitive dysfunction, opthalmoparesis, conscious impairment, behavioral disturbance, and corticospinal dysfunction. Here, we describe the case of a 75‐year‐old male patient who presented to the emergency department of our hospital with agitation and somnolence for one day. He had poorly controlled hypertension. There was no previous history of stroke, diabetes mellitus, hyperlipidemia, known cardiac disease, or smoking history. There was no seizure, recent headache, or visual disturbance. The patient was somnolent and not oriented to time, person, or place. Neurological examination did not show any focal weakness or vertical eye movement restrictions. Other systemic examinations, including those of the respiratory and cardiovascular systems, were unremarkable. Extensive laboratory investigations excluded potential metabolic, infectious, endocrine, or toxic etiologies. The patient did not have any recent history of drug misuse, including benzodiazepines. Brain MRI with diffusion‐weighted imaging showed an acute bilateral thalamic infarct. Cerebral angiography was unremarkable. The patient was treated with low molecular weight heparin 60 mg subcutaneously, aspirin 300 mg daily, and haloperidol 5 mg twice daily for agitation. After two weeks of intrahospital treatment, his condition improved (consciousness and orientation massively improved).

The most perilous environmental hazards arise from the contamination of water by heavy metal ions, owing to the non-biodegradability of these metals, as well as their rapid dissemination throughout components of the environment via the food chain. Nano-based adsorbents have been used for the adsorption removal of many heavy metal cations, but separating and recycling them represent significant difficulties in processing. Magnetic core–double shell nanoparticles provide an attractive solution for processing issues, since they are stable and can be easily separated and recycled. Moreover, the shell thickness, composition, and porosity can be easily tuned. In this work, two samples consisting of magnetic core@TiO _2 @mesoSiO _2 nanoparticles with two shell thicknesses (Mag-T-S-0.2 and Mag-T-S-0.4), along with a magnetic core@SiO _2 @TiO _2 nanoparticle sample (Mag-S-T), were synthesized and characterized by TEM, XRD, magnetic strength measurement and zeta potential. TEM images show the developed core–double shell structure with double shell ranging from 60 to 73 nm. The XRD results indicate the impact of the outer shell on the diffraction pattern. The zeta potential shows that all samples had a negative charge at pH over 4. The magnetic character was suppressed after the formation of the double-shell coating; however, the magnetic core–double shell nanoparticles still had magnetization and could be separated when an external magnetic field was applied. The heavy metal adsorptive ability of Mag-T-S-0.2, Mag-T-S-0.4, and Mag-S-T samples was explored to investigate the effects of shell type and thickness along with kinetic, isotherm, and thermodynamic study. The investigated heavy metals included Cd(II), Ni(II), Mn(II), Pb(II), and Cu(II). The results indicate that, for Mag-T-S-0.2, the equilibrium state occurred after 15 min contact time, with adsorption capacity of 238, 230, 210.6, 181.8, and 245.8 mg/g for Cd(II), Ni(II), Mn(II), Pb(II), and Cu(II), respectively. For Mag-T-S-0.4, the equilibrium state occurred after 15 min contact time, with adsorption capacity of 241, 237.6, 173.8, 189.6, and 257.2 mg g ^−1 , respectively. For Mag-S-T, the equilibrium state occurred after 25 min contact time, with adsorption capacity of 137.8, 131.4, 221, 189.6, and 149.4 mg g ^−1 , respectively. When pseudo-first-order and pseudo-second-order kinetic models were applied to investigate the time interval adsorption data for Mag-T-S-0.2, Mag-T-S-0.4, and Mag-S-T samples, the second-order kinetic model was found to be more suitable for describing the process, indicating a fast adsorption mechanism. The adsorption data did not fit well with the Langmuir model, while they did fit well with the Freundlich model, suggesting heterogeneous material surfaces and multi-layer adsorption. Thermodynamic investigations confirmed the spontaneous nature of adsorptive removal, which helps to promote magnetic core@TiO _2 @mesoSiO _2 and magnetic core@SiO _2 @TiO _2 nanoparticles as effective adsorbents for wastewater treatment.

Groundwater is a critical resource for various human activities, yet it faces contamination risks from agricultural, industrial, and domestic sources. This study aimed to evaluate groundwater in Morocco’s Sidi Allal region using the groundwater pollution index (GPI) and diagnose nitrate pollution. The study included 45 groundwater wells from the study area, and physicochemical parameters such as pH, electrical conductivity, cations, and anions were examined in the laboratory. The geographic information system (GIS) was used to determine the spatial distribution of groundwater quality parameters. The groundwater pollution index and nitrate pollution index (NPI) were determined. The inverse distance weighting method (IDW) was used to create a spatial distribution map. The results indicated that the calculated GPI values ranged from 0.856 to 7.416, with an average of 2.06. About 40% of groundwater samples were highly polluted and unsuitable for drinking. The NPI values ranged between −0.74 and 10.5, with an average of 5.1. About 64% of the total groundwater samples were considered highly polluted according to the NPI classification, suggesting that the groundwater was unsuitable for drinking purposes. The spatial distribution map revealed the availability of appropriate groundwater in the central area of the study area and inappropriate groundwater near the Esbou River and Nassour Canal. The findings of this study revealed high concentrations of nitrates in groundwater samples in the central part of the study area, indicating that this increase in nitrates may be due to intensive use of nitrogen fertilizers in agricultural activities and sewage waste.

Abstract A previously healthy middle‐aged man with no vascular risk factors developed a hemorrhagic stroke. He had been using tramadol due to erectile dysfunction for 2 years. So, the patient developed right basal ganglia due to tramadol addiction.

Spiny-like spherical copper metal–organic frameworks (SSC-MOFs) were prepared and characterized via SEM, TEM, EDS, XRD, FTIR and the BET surface area. The fabricated SSC-MOFs were applied to develop a procedure for the microextraction of trace arsenic(III) for preconcentration. The results show that a copper- and imidazole-derived metal–organic framework was formed in a sphere with a spiny surface and a surface area of 120.7 m2/g. The TEM confirmed the perforated network structures of the SSC-MOFs, which were prepared at room temperature. The surface functional groups were found to contain NH and C=N groups. The XRD analysis confirmed the crystalline structure of the prepared SSC-MOFs. The application for the process of microextracting the arsenic(III) for preconcentration was achieved with superior efficiency. The optimum conditions for the recovery of the arsenic(III) were a pH of 7 and the use of a sample volume up to 40 mL. The developed SSC-MOF-derived microextraction process has an LOD of 0.554 µg·L−1 and an LOQ of 1.66 µg·L−10. The developed SSC-MOF-derived microextraction process was applied for the accurate preconcentration of arsenic(III) from real samples, including food and water, with the promised performance efficiency.

Herein, Fe3O4 core-TiO2/mesoSiO2 and Fe3O4 core-mesoSiO2/TiO2 double shell nanoparticles were prepared by first (R1) and second (R2) routes and applied for the removal of methylene blue. The reported adsorption capacities for R1-0.2, R1-0.4 and R2 samples were 128, 118 and 133 mg.g−1, respectively, which were obtained after 80 min as equilibrium contact time, and pH of 6 using a methylene blue concentration of 200 ppm. The adsorption of methylene blue using the prepared Fe3O4 core-meso SiO2/TiO2 double shell was analyzed by kinetic and isotherms models. In addition, thermodynamic investigations were applied to assess the spontaneous nature of the process. The obtained results confirmed that the pseudo-second order model is well fitted with the adsorption data and the Freundlich-isotherm assumption suggested a multilayer adsorption mechanism. In addition, results of the thermodynamic investigation indicated that ΔG° was in the range of −2.3 to −6.8 kJ/mol for R1-0.2, −2.8 to −6.3 kJ/mol for R1-0.4 and −2.0 to −5.2 kJ/mol for R2. In addition, the ΔH° and ΔS° values were found in the range of 26.4 to 36.19 kJ.mol−1 and 94.9 to 126.3 Jmol−1 K−1, respectively. These results confirm that the surfaces of Fe3O4 core-mesoSiO2/TiO2 and Fe3O4 core-TiO2/mesoSiO2 double shell exhibit a spontaneous tendency to adsorb methylene blue from the aqueous solutions. The achieved performance of Fe3O4 core-meso SiO2/TiO2 and Fe3O4 core-TiO2/meso SiO2 double shell as adsorbent for methylene blue removal will encourage future research investigations on the removal of a broad range of contaminants from wastewater.

Intensive care for a hypertensive mother with preeclampsia or eclampsia is crucial for both maternal and neonatal outcomes. This study highlights the level of morbidity and mortality among women with preeclampsia and eclampsia admitted to the intensive care unit. Methods. This retrospective study was conducted in Mogadishu, Somalia, at the Mogadishu Somali Türkiye Training and Research Hospital from February 2019 to July 2022. The study focused on the different complications, managements, and final outcomes of preeclampsia and eclampsia mothers admitted to the intensive care unit. The data was retrieved from the electronic records of patients admitted to the intensive care unit. Results. During our study period, a total of 237 patients were identified as having preeclampsia/eclampsia, of whom 71 required intensive care admission. The mean age of the studied patients was 25 ± 6 years. The most common reason for being taken to the intensive care unit (ICU) was having a seizure (n = 33, 46.5%), followed by having very high blood pressure (n = 20, 28.2%), and being confused (n = 18, 25.3%). Peripartum infection was the most common maternal complication during ICU admission (66.7%), followed by cardiac-related arrhythmia (66.7%), postpartum bleeding (48%), acute kidney injury (18.4%), HELLP syndrome (16.4%), severe anemia (9.6%), and stroke (8.7%). Among patients, 65 (91.5%) needed mechanical ventilation. About 11.1% of these patients died during hospitalization. There were associations between mortality and some complications, particularly acute kidney injury p value less than 0.02) and peripartum infection (p value less than 0.003). Conclusion. Hypertensive disease of pregnancy (preeclampsia/eclampsia) requiring intensive care unit admission has a very high morbidity and mortality rate.

Introduction: Neurologic disorders are common reasons for emergency consultations. Most neurologic disorders seen in the emergency department (ED) are life-threatening and require urgent treatment. The goal of this study is to investigate the pattern of neurological disorders among patients evaluated in the ED. Methods: This is a cross-sectional study conducted in the ED of Mogadishu Somali Turkish Training and Research Hospital, from July 2021 to February 2022. The clinical and epidemiological characteristics of adult patients with neurologic manifestations in the ED were evaluated. Age, gender, distribution of neurological disease manifestations, neurological examination findings, and neurological diagnoses made by consultant neurologists were assessed. Results: During the study period, 321 patients were assessed (3.7 % of all ED admissions). The majority of the patients in the study were above 50 years of age (62.6% male). Hypertension was the most common comorbidity among these patients with 122 (38%) cases, followed by diabetes mellitus with 65 (20.2%), and heart diseases with 26 (8.1%) cases. The main reasons for neurology consultations were altered mental status with 141 (44%) cases, motor weakness with 102 (31.8%), seizures with 33 (10%), headache with 17 (5.3%), and vertigo with 9 (2.8%) cases. 196 (61%) had hemiplegia, 60 (18.7%) had consciousness impairment, and 38 (11.8%) had normal neurological examination. The most frequent neurological diagnoses were ischemic strokes with 125 (39%) cases, hemorrhagic strokes with 65 (20.2%), epileptic seizures with 28 (8.7%), and metabolic encephalopathies with 13 (4%) cases. The median duration of the neurology consultations was 20 minutes. 251 (78%) of the patients were admitted to the hospital, while 70 (22%) were discharged from the emergency department. After neurology consultation, the neurology department made the most admissions with 226 (90%) cases, while 25 (10%) were admitted by other departments. Of those admitted, 186 (74.2%) were admitted to the neurology ward, and 65 (25.8%) were admitted to the intensive care unit. Conclusion: In our study, neurologic emergencies accounted for 3.7% of all emergency admissions. Stroke, epileptic seizures, cerebral venous thrombosis, encephalopathies, and acute spinal cord diseases were the most common neurological disorders. The admission rate was very high following neurologic assessment by neurologists.

Abstract Transient global amnesia (TGA) is an uncommon clinical syndrome characterized by short‐term memory loss and disorientation that resolves in 24 h. Here, we report a 60‐year‐old male patient who presented with a sudden onset of disorientation and short‐term memory loss and started to ask about his whereabouts and what happened. He had no significant past medical or psychiatric disorder. Likewise, the patient did not have a recent history of head trauma, substance abuse, loss of consciousness, seizure disorder, or migraine. Neurologic examination was normal except for mild disorientation and short‐term memory impairment. He had a score of 18/30 on the mini‐mental state examination. Extensive laboratory investigations did not show any abnormal findings. Brain MRI and EEG were normal. His memory improved and returned to a normal baseline within 24 h from the onset. After the exclusion of potential causes and the patient returned to a normal state of memory, the diagnosis of transient global amnesia was made. At the follow‐up visit, the patient was in a state of normal function without a recurrence of memory impairment. Here, we presented this interesting case of transient global amnesia. TGA is a diagnosis of exclusion and is essential to keep in mind when evaluating a patient with acute onset of short‐term memory impairment, especially when etiological investigations reveal no potential cause.

Central neurocytomas are WHO grade II neuroepithelial intraventricular tumors with fairly characteristic imaging features that can cause obstructive hydrocephalus and manifest as increased intracranial pressure. Here we present the case of a 32-year-old man with no known chronic disease presenting with headache and papilledema of 2 months duration. Brain magnetic resonance imaging revealed a mass lesion growing from the septum pellucidum level into both lateral ventricles, measuring approximately 67x60 mm in size, containing cystic areas consistent with neurocytoma.

Developing and improving adsorbent materials for wastewater treatment have become crucial for achieving recyclable water and keeping the environment safe. Carbon materials are modified with alumina (Al2O3) using various doping ratios and a solvothermal treatment. The process aims to combine the advantages of stable carbon and alumina materials with an efficient adsorbent for methylene blue removal. Fabricated materials including carbon and carbon/alumina derivatives were characterized with TEM, SEM, EDS, XRD, and FTIR, revealing successful surface modifications. The carbon materials exhibited pore diameters between 23 and 39 µm, while the modified ones showed pore diameters between 1.68 and 6.08 µm. The alumina nanoparticles were formed on a carbon surface with a particle size between 174 nm and 179 nm. Fabricated adsorbents were applied for the removal of methylene blue by adsorption at pH 4. The equilibrium and steady state adsorption stage was achieved after 2 h of reporting fast adsorption behavior. Low ratio carbon doping with alumina improved the adsorption capacity for methylene blue removal, while the excessive doping of carbon materials with alumina led to a reduction in adsorption efficiency. The application of pseudo-first-order and pseudo-second-order kinetic models indicated a fast adsorption mechanism, which agreed with the second-order model. The adsorption capacity for methylene blue was found to be 234 mg/g. Adsorption-isotherms including the Langmuir and Freundlich models were applied to investigate the adsorption mechanism. The results indicate that the Langmuir model fits with the adsorption data, which suggests a monolayer adsorption process.

The palm-pruning leaves considered as valuable source for low cost adsorbent materials. Such application, enhance the environmental conditions by reducing the bad effects from un-managed palm-pruning leaves such as spreading insects. Herein, the palm-pruning leaves were treated with by water and acid washing to produce cleaned palm leaves (CPL) and then impregnation with iron(III) chloride and thermally treated to produce palm leaves/iron oxide- nanocomposite (PL/IO-NC). The prepared materials were applied for adsorption of some toxic metal ions from solutions. The original palm-pruning leaves as well as the treated adsorbent were characterized by SEM, EDS, FTIR, XRD. Results showed the formation of spots iron oxide nanoparticles onto the palm-pruning leaves. The efficiency of the treated adsorbent for uptake of Mn(II), Co(II) and Pb(II) was studied in term of kinetic, isotherm and thermodynamic to optimize and evaluate the effectiveness of the palm-pruning leaves treatment. The adsorption data was found to be more comfortable with Second order kinetic-model while the isotherm of Langmuir wasn’t suitable and the adsorption data was in agreement with Freundlich assumption. The values of ΔG° in the range (−5.8 to −3.5 kJ/mol) for Mn(II), (−4.2 to −2.1 kJ/mol) for Co(II), (−3.4 to −2.3 kJ/mol) for Pb(II), confirm the confirm the spontaneous and physical nature of the adsorption process. Keywords: Palm-pruning leaves, Nano composite, Manganese, Cobalt, Lead, ICPMS

The possibility for an ecologically friendly and simple production of gold nanoparticles (AuNPs) with Chaga mushroom (Inonotus obliquus) (Ch-AuNPs) is presented in this study. Chaga extract’s reducing potential was evaluated at varied concentrations and temperatures. The nanoparticles synthesized were all under 20 nm in size, as measured by TEM, which is a commendable result for a spontaneous synthesis method utilizing a biological source. The Ch-AuNPs showed anti-cancer chemotherapeutic effects on human brain cancer cells which is attributed to the biofunctionalization of the AuNPs with Chaga bioactive components during the synthesis process. Further, the photothermal ablation capability of the as-prepared gold nanoparticles on human brain cancer cells was investigated. It was found that the NIR-laser induced thermal ablation of cancer cells was effective in eliminating over 80% of the cells. This research projects the Ch-AuNPs as promising, dual modal (chemo-photothermal) therapeutic candidates for anti-cancer applications.

In this work, metal organic frameworks (A100 Al-based MOFs) were used in dispersive solid-phase microextraction (DSPME) for the isolation and preconcentration of the carbaryl from vegetable, fruit and water samples. The A100 Al-based MOFs showed excellent behavior for the adsorption of carbaryl from a water–ethanol solution; additionally, carbaryl was easily desorbed with ethyl acetate for detection by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-TMS). The analytical process of DSPME together with UPLC-TMS provides the accurate monitoring of trace carbaryl residues. The results show that the optimal recovery% of carbaryl was obtained at a sample apparent pH of 5, with the application of 1 mL of ethyl acetate to elute the carbaryl from the A100 Al-based MOFs. The limit of detection (LOD) and the limit of quantification (LOQ) were 0.01 mg.L−1 and 0.03 mg.L−1, respectively. The RSD% was 0.8–1.9, and the preconcentration factor was 45. DSPME and UPLC-TMS were successfully used for the isolation and detection of carbaryl in food and water samples.

A biomass-derived adsorbent was simply prepared and applied as efficient and low-cost solid-phase supports. The adsorbent material was characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), surface area analysis and Fourier transform infrared (FTIR) spectroscopy. The amorphous structure of the prepared adsorbent was indicated from the XRD. The prepared adsorbent exhibited surface functional groups such as carbonyl and hydroxyl groups, which enhance the application of DSPE. An accurate separation and preconcentration of Cr(III), Fe(III), Co(II) and Ni(II) prior to ICP-MS detection was achieved using the biomass-derived adsorbent. The extraction process was performed at pH 4 using 1 mL of 0.5 N nitric acid for elution and recovery of ions. The prepared biomass-derived adsorbent showed efficient performance for extraction application, exhibiting a preconcentration factor of 50 and LODs of 1.4, 2.4, 1.9 and 3.0 µg.L−1 for Cr(III), Fe(III), Co(II) and Ni(II), respectively, while the LOQs were reported as 4.1, 7.3, 5.7 and 8.9 µg.L−1 for Cr(III), Fe(III), Co(II) and Ni(II), respectively. The DSPE procedure presented was successfully applied to the determination of the Cr(III), Fe(III), Co(II) and Ni(II) contamination in some food samples.

Cardiac tissue engineering (CTE) aims to generate potential scaffolds to mimic extracellular matrix (ECM) for recreating the injured myocardium. Highly porous scaffolds with properties that aid cell adhesion, migration and proliferation are critical in CTE. In this study, electrospun porous poly (l-lactic acid) (PLLA) porous scaffolds were fabricated and modified with different ECM derived proteins such as collagen, gelatin, fibronectin and poly-L-lysine. Subsequently, adult human cardiac fibroblasts (AHCF) were cultured on the protein modified and unmodified fibers to study the cell behavior and guidance. Further, the cytotoxicity and reactive oxygen species (ROS) assessments of the respective fibers were performed to determine their biocompatibility. Excellent cell adhesion and proliferation of the cardiac fibroblasts was observed on the PLLA porous fibers regardless of the surface modifications. The metabolic rate of cells was on par with the conventional cell culture ware while the proliferation rate surpassed the latter by nearly two-folds. Proteome profiling revealed that apart from being an anchorage platform for cells, the surface topography has modulated significant expression of the cellular proteome with many crucial proteins responsible for cardiac fibroblast growth and proliferation.

The contamination of water surfaces by mercury is a dangerous environmental problem due to its toxicity, which leads kidney damage. Activated carbon from mixed recyclable waste modified by phosphonium-based ionic liquid (IL-ACMRW) was therefore prepared and evaluated for Hg(II) remediation. The activated carbon used in this study was prepared from mixed waste, including cardboard, papers and palm wastes as cheap raw materials. The mixed Recyclable Waste Activated Carbon was combined with trihexyl(tetradecyl)phosphonium Bis2,4,4-(trimethylpentyl)phosphinate (Cyphos® IL 104) ionic liquid to form an adsorbent with organic-inorganic content, in order to improve the Hg(II) uptake from aqueous solutions. FTIR confirms the presence of P, C=O and OH after this modification. The adsorption process was investigated and the evaluated results showed that the capacity was 124 mg/g at pH 4, with a contact time of 90 min, an adsorbent dose of 0.4 g/L, and a Hg(II) concentration of 50 mg/L. This Hg(II) adsorption capacity is superior than that reported in the literature for modified multiwall carbon nanotubes. The adsorption of Hg(II) on the modified activated carbon from mixed recyclable waste was found to follow the pseudo second-order kinetics model. Isotherms of adsorption were analyzed via Freundlich and Langmuir models. The results indicated that Freundlich is the best model to describe the process, suggesting multilayer adsorption.

In October 2005 a devastating earthquake caused extensive damage among populations in Pakistan administered Kashmiri Region and parts of North Western Frontier. In addition to the loss of more than 87`000 human lives and 70`000 injured, many livestock namely buffaloes, cattle and goats were lost. This eroded the livelihoods of families that solely relied on livestock and agriculture for their economic survival. The International Committee of the Red Cross together with the German Red Cross (ICRC/ GRC) and the Kashmiri authorities formulated a project that sought to restore the livelihoods of the most vulnerable households to a level comparable to before the earthquake. The project adapted an agro-vet and micro-economic approach, part of which included the provision of a milking cow and calf. This report indicates that antibiotics and homoeopathic medicines provide similar levels of protection against mastitis (Spranger, 2000). Preventive measures like vaccinations, disinfectant footbaths and reducing stress during the critical time of calving goes a long way towards improving the overall health of the dairy cows (Dettloff, 2005). Although milking is in many cases still done by hand, pre-milking and post-milking hygienic procedures, such as udder washing and drying greatly decrease prevalence of mastitis.

Wilson's disease (WD) is a genetic disorder of copper metabolism that is inherited as an autosomal recessive (AR) due to mutations in the ATP7B gene, which is involved in intracellular copper transport. Approximately 40% to 50% of the patients present with neurological symptoms as their first symptom. The most common neurological symptoms are dysarthria, gait abnormalities, ataxia, dystonia, tremor, parkinsonism, and drooling. This case report aims to present a diagnostically challenging case of WD presenting with neurological symptoms. The 38-year-old male patient was admitted with complaints of imbalance, gait disturbance, weakness in the legs, speech impairment, tremors in the hands, syncope, and drooling. The MRI primarily revealed FLAIR, T1, and T hyperintensities in the bilateral globus pallidus of the basal ganglias. At first, the patient was evaluated according to the Leipzig scoring and received one point from the serum ceruloplasmin level and two points from the neurological symptoms and was evaluated as "possible WD" with a total of three points. 24-hour urine copper was collected during and after the D-Penicillamine challenge. After the test, there was an increase of more than 5 times the upper limit. The Leipzig score was recalculated, and a diagnosis of WD was made with a score of five. Even cases without important diagnostic findings such as Kayser-Fleischer ring or high 24-hour urine copper should be evaluated according to the Leipzig score. It is vital to distinguish WD in patients with young-onset movement disorder and neurological symptoms. [ABSTRACT FROM AUTHOR]

Introduction: Spontaneous Intracerebral hemorrhage (ICH) in young patients is less common and not well studied compared to ICH in older patients. The etiology, risk factors and outcome of ICH in young patients may have regional and ethnic differences. The study aims to investigate the clinical characteristics, risk factors, etiology and outcome of spontaneous intracerebral hemorrhage in young adults in Somalia. Methods: The study enrolled 168 young patients with ICH (16– 50 years) admitted to the neurology department of a tertiary hospital from 2019 to 2022. The information about the demographic details, documented ICH risk factors, etiology and patients' clinical status were retrieved. The etiology of ICH was determined based on clinical, laboratory and radiological findings. Intra-hospital survival status and associated factors were assessed. Results: The mean age of the patients was 35± 8.6 years. 99 (59%) of patients were male while 69 (41%) were females. Hypertension 48 (29%) was the most common risk factor, followed by substance abuse. Hypertensive hemorrhage was the most common etiology of ICH 60 (35.7%), followed by cerebral venous thrombosis (CVT) 5(15%), substance abuse 23 (13.7%) and arteriovenous malformation (AVM) in 10 (6%). AVM, CVT, cavernoma, eclampsia, substance abuse and cryptogenic etiology were more common in the 2nd and 3rd decades whereas hypertension was more common in the 4th and 5th decade. Intrahospital mortality was 28% in this study. Factors predicting intrahospital mortality were hematoma volume of greater than 30mL, thrombolytic etiology, brainstem ICH location, substance abuse related etiology, presence of associated mass effect, low GCS score on admission, high systolic blood pressure on admission, and the presence of chronic renal failure. Conclusion: In this study, hypertension, substance abuse, CVT and vascular malformation are the leading causes of ICH in young adults. Intracerebral hemorrhage in the young has different spectrum of etiologies and factors associated with short-term mortality compared to older patients. [ABSTRACT FROM AUTHOR]

Sturge-Weber syndrome is a rare, sporadic, progressive neurocutaneous condition that presents with congenital hamartomatous malformations, epilepsy, and a variety of facial symptoms. We discussed a rare case of an eighteen-year-old female child who came to our neurology department with status epilepticus, mental impairment, and a port-wine in the lateral left side of her face. We diagnosed Sturge-Weber syndrome after a thorough neurological and radiological evaluation. The purpose of presenting this case is to illustrate both the characteristic presentation and the complications associated with managing Sturge-Weber syndrome. [ABSTRACT FROM AUTHOR]

Todd's paralysis (TP) is relatively uncommon condition that can occur immediately after an epileptic seizure. It is a heterogeneous clinical syndrome that presents with acute-onset neurological findings, such as paralysis, paresthesia, aphasia, hemianopsia, and an altered state of consciousness. This may be accompanied by cytotoxic edema on diffusion MRI. This case illustrates a 28-week pregnant patient with TP who presented with acute stroke-like clinical and radiological findings. The patient was presented to the emergency room with left side weakness following focal onset generalized seizure. Magnetic resonance imaging demonstrated diffusion restriction which led to the initial consideration of acute stroke. However, after the disappearance of the neurologic deficit and the resolution of the diffusion restriction in the control MRI, the diagnosis shifted away from acute stroke to the postictal TP. It is important to keep in mind that TP may mimic acute stroke even in the presence of an acute brain lesion in the brain MRI. The differentiation is necessary as each of them has completely different treatment and etiology. [ABSTRACT FROM AUTHOR]

Cerebral sinovenous thrombosis (CSVT) encompasses a spectrum of disorders involving thrombosis of the cerebral venous system. As shown by previous epidemiological studies, the prevalence of cerebral sinovenous thrombosis is 4– 7 cases per million people. Nephrotic syndrome was very rarely associated with thrombosis cerebral veins or sinuses. Hypercoagulability and thrombotic complications in nephrotic syndrome are most commonly seen in deep veins of the lower extremities and renal veins. Our case highlights a unique scenario in which cerebral sinovenous thrombosis was the initial presentation of nephrotic syndrome in a patient that was not an important past medical or surgical problem. The patient was brought to the emergency department with severe headache, vomiting, altered mental status, and generalized body swelling. Laboratory results showed proteinuria, hypoalbuminemia and hyperlipidemia. Non-contrast brain CT demonstrated hemorrhagic venous infarct associated with vasogenic edema. A subsequent brain MR venogram demonstrated occlusion of superior sagittal and right transverse sinuses. She was managed with low molecular weight heparin and intervenous corticosteroids then shifted to rivaroxaban and oral steroids, respectively, which resulted in massive clinical improvement and resolution of thrombus.

Mucormycosis is a potentially fatal condition with a high mortality rate, particularly when there is extra nasal involvement, and it is rare for patients with fungal brain disease to survive. It mostly affects patients who are metabolically or immunologically compromised, which constitutes one of the three classical stages of the progression of Rhino-Orbito-Cerebral Mucormycosis (ROCM). Stage I: infection of the nasal mucosa and paranasal sinuses; Stage II: orbital involvement; Stage III: cerebral involvement.Here, we report a case of rhino-orbital cerebral mucormycosis in a 14-year-old girl with no known risk factor who presented with periorbital edema, right eye proptosis, fever, and extreme facial pain, which progressively worsened to confusion and left leg weakness in 3 days after admission. The final diagnosis was rhino-orbital-cerebral mucormycosis. The infection was successfully treated using liposomal amphotericin and surgical debridement to remove infected orbital tissue. Mucormycosis is a potentially fatal disease that necessitates prompt diagnosis and treatment. Children are rarely infected with mucormycosis. The majority of studies show that people are typically between 40 and 50 years old. ROCM is typically diagnosed using clinical symptoms and histopathologic evaluation; however, imaging is critical in determining the presence of intracranial lesion s. The standard treatment for ROCM is amphotericin B at a recommended dose of 1.0– 1.5 mg/kg/day for weeks or months, depending on the clinical response and severity of adverse drug reactions, particularly nephrotoxicity.Rhino-orbital cerebral mucormycosis in a healthy female child is uncommon; early diagnosis and prompt treatment with Amphotericin B should be necessary. Devastating consequences will result from a delayed diagnosis. [ABSTRACT FROM AUTHOR]

Introduction: Epilepsy is a neurological disorder characterized by abnormal, fast, synchronous neuronal discharge from the cerebral cortex. This abnormal excitation of the brain is usually short and self-limiting and can last anywhere from a few seconds to a few minutes. Neuroimaging and electroencephalography (EEG) are two widely used techniques to differentiate, verify, or exclude the diagnosis of epilepsy. The study aims to identify the frequency of EEG and MRI abnormalities in pediatric epilepsy and their correlations, aiming to improve diagnostic and treatment methods for these children.Materials and Methods: In this cross-sectional retrospective study, we evaluated pediatric patients aged 0– 18 years who visited the Neurology Polyclinic between July 2022 and July 2023, were diagnosed with epilepsy in accordance with the ILAE 2014 epilepsy guidelines, and had undergone neuroimaging at the hospital's radiology department. Demographic information and clinical data, including the patient's age, gender, history of trauma, and congenital infection, were assessed. In all patients, a surface electroencephalogram (EEG) and brain magnetic resonance imaging (MRI) were performed.Results: Our study recruited 102 pediatric patients aged between 0– 18 years, including 63 (61.8%) boys and 39 (37.2%) girls. An electroencephalogram (EEG) and MRI study have been done on all patients. An abnormal EEG study was seen in 79 (77.45%) participants, and an abnormal MRI was noted in 45 (44.1%) patients. The EEG and MRI were both abnormal in 34 cases (33.3%). The study found no significant correlation between magnetic resonance imaging and electroencephalographic findings (P =0.779).Conclusion: We observed multiple abnormalities on neuroimaging in pediatric epileptic patients. Even though our sample size was small, our results demonstrated that there is no statistically significant relationship between EEG and MRI results. [ABSTRACT FROM AUTHOR]

Introduction: The door-to-balloon time, the time between a patient's arrival at the hospital and percutaneous coronary intervention, is crucial for managing myocardial infarction. Aiming for less than 90 minutes is recommended, as shortened times are associated with improved outcomes. However, limited healthcare resources, infrastructure, transportation and poverty impact management, leading to poorer outcomes and delayed door to balloon time. Addressing these challenges and their causes is essential for optimal care.Methodology: A retrospective analysis of 103 patients' medical history records from May 2022 to June 2023 at the Mogadishu Somali Turkish Training and Research Hospital in Somalia was conducted. The data was mainly collected from the hospital's electronic medical records system, analyzing patient demographics, clinical characteristics, and angiographical records. The study analyzed variables responsible for door-to-balloon (D2B) time delay, patient angiography results, cause of delay, procedure length, etc.Results: A study of 103 patients who had angiography performed between May 2022 and July 2023 was done. The predominant gender in the study was 73% male, with a mean age of 58 years. The most common risk factors were hypertension (33%), smoking (38%), and diabetes (39%). Of all the vessels, the Left Anterior Descending (LAD) was the most commonly obstructed (63%). Time delays from door-to-balloon were frequent, median door-to-balloon time was 169 minutes, frequently brought on by social problems and financial limitations. The majority (77.4%) of the patients had only percutaneous angiography (PCI), while 22.6% were recommended for bypass following PCI of the infarct-related artery (IRA). Complications in the delayed treatment group were the main cause of the death rate of 24.2%.Conclusion: Door-to-balloon time is crucial for acute myocardial infarction treatment which is challenging in impoverished countries like Somalia. Investments in healthcare infrastructure, public health education, and emergency services can improve patient outcomes. [ABSTRACT FROM AUTHOR]

Introduction: Myocardial infarction and cardiovascular disease are significant global health issues, particularly in Somalia. The Somali population faces challenges due to armed conflict, limited education, and underdeveloped healthcare infrastructure. Cardiovascular risk factors like diabetes, hypertension, and obesity are prevalent, and Somali people face increased susceptibility.Methods: This study examined Somalia residents' perceptions, attitudes, and behaviors towards myocardial infarction using a cross-sectional paper-based questionnaire. The sample consisted of 313 urban residents in Mogadishu, aged 20 and above. The questionnaire was written in Somali and was designed for the demographic. Knowledge, attitude, and practice scores were categorized into two groups, with associations between knowledge, attitude, and practice with sociodemographic and health characteristics assessed using Logistic Regression.Results: This study analyzed data from A random sample of participants who arrived at the hospital for various reasons regarding their perceptions, attitudes, and responses towards myocardial infarction. The mean age was 42 ± 19 years, with 54% being male and 46% female. Hypertension was the most common comorbidity, followed by dyslipidemia and diabetes. Over half of the respondents had no formal education, and only 3.8% had a smoking history. About 5.7% had a previous history of myocardial infarction. The mean knowledge score was 11.07 ± 0.697, with 53.35% of respondents not knowing enough about myocardial infarction. The majority of the patients showed a favorable attitude, but only a slight majority could recognize symptoms of myocardial infarction. The majority of the patients had inadequate practice and behavior, with 53.6% not practicing regularly or engaging in sports.Conclusion: The research highlights gaps in Mogadishu's Somali community's knowledge and practices regarding myocardial infarction. It emphasizes the need for health education, primary care, and community involvement to improve cardiovascular health awareness and reduce MI incidence. [ABSTRACT FROM AUTHOR]

Groundwater is a critical resource for various human activities, yet it faces contamination risks from agricultural, industrial, and domestic sources. This study aimed to evaluate groundwater in Morocco's Sidi Allal region using the groundwater pollution index (GPI) and diagnose nitrate pollution. The study included 45 groundwater wells from the study area, and physicochemical parameters such as pH, electrical conductivity, cations, and anions were examined in the laboratory. The geographic information system (GIS) was used to determine the spatial distribution of groundwater quality parameters. The groundwater pollution index and nitrate pollution index (NPI) were determined. The inverse distance weighting method (IDW) was used to create a spatial distribution map. The results indicated that the calculated GPI values ranged from 0.856 to 7.416, with an average of 2.06. About 40% of groundwater samples were highly polluted and unsuitable for drinking. The NPI values ranged between −0.74 and 10.5, with an average of 5.1. About 64% of the total groundwater samples were considered highly polluted according to the NPI classification, suggesting that the groundwater was unsuitable for drinking purposes. The spatial distribution map revealed the availability of appropriate groundwater in the central area of the study area and inappropriate groundwater near the Esbou River and Nassour Canal. The findings of this study revealed high concentrations of nitrates in groundwater samples in the central part of the study area, indicating that this increase in nitrates may be due to intensive use of nitrogen fertilizers in agricultural activities and sewage waste.
