Background: Toumbak, a form of smokeless tobacco made from Nicotiana rustica and sodium bicarbonate, is widely used in Sudan and poses potential health risks, particularly concerning cardiovascular function. Despite its high prevalence, especially among adult males, limited data exist regarding its impact on blood pressure.Objective: To assess and compare blood pressure parameters among Sudanese Toumbak users and non-users, and to investigate the association between Toumbak use, age, and gender with systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP).Methods: A comparative cross-sectional study was conducted from 2022 to 2025 among 1000 Sudanese adults (500 Toumbak users and 500 matched non-users) aged 18–60 years in Khartoum State. Blood pressure measurements were recorded using a digital sphygmomanometer following WHO guidelines. Independent t-tests and ANOVA were used to compare SBP, DBP, and PP between groups. A p - value < 0.05 was considered statistically significant.Results: Toumbak users exhibited significantly elevated SBP (141.7 ± 21.9 mmHg), DBP (89.3 ± 6.0 mmHg), and PP (52.4 ± 19.3 mmHg) compared to non-users (SBP: 121.2 ± 3.2 mmHg, DBP: 80.5 ± 3.8 mmHg, PP: 40.7 ± 3.9 mmHg), with p < 0.001 for all parameters. Males demonstrated significantly higher SBP (145.6 ± 24.0 mmHg) and PP (56.7 ± 22.1 mmHg) than females (SBP: 137.8 ± 18.6 mmHg, PP: 48.2 ± 14.5 mmHg). While no statistically significant differences were observed in BP across age groups, adolescents and middle-aged users had the highest SBP.Conclusion: Toumbak use is significantly associated with elevated blood pressure and increased cardiovascular risk, particularly among male users. These findings highlight the need for targeted public health interventions and awareness campaigns addressing the health consequences of smokeless tobacco in Sudan.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a major cause of illness and death worldwide, and inhalers are often used to manage its symptoms. However, patients’ ability to use inhalers correctly is crucial for the effectiveness of treatment.  Incorrect technique can lead to poor management of the disease and limit the effectiveness of the medication. This study aimed to assess the inhalation technique of patients with COPD who visited a teaching hospital in Chitwan.Methodology: A descriptive cross-sectional study was conducted among patients with COPD who had been using a dry powder inhaler through a rotahaler device for at least 1 month and were attending the Medicine and Respiratory OPD of the teaching hospital in Chitwan. A convenience sampling technique was used to select a total of 103 participants. An observational checklist was used to assess inhalation technique, and a structured interview schedule was used to collect socio-demographic information. Descriptive statistics were used to analyze the obtained data in SPSS version 20 for Windows.Findings: The mean age of the 103 respondents was 70.1 ± 9.56 years, and 62.1% of them were female. While 78.6% had observed a demonstration of the inhalation technique, only 5.8% of the respondents performed the inhalation technique correctly, and 94.2% performed it incorrectly. Only 22.3% of the participants were able to perform at least one critical step of the inhalation technique. The most commonly observed errors included placing the mouthpiece between the lips and teeth (20.4%), breathing out through the mouth (21.4%), and inhaling the powder forcefully and deeply (26.2%).Conclusion: Patients with COPD attending the teaching hospital in Chitwan exhibited incorrect inhalation technique, which can affect the effectiveness of medication and disease management. Healthcare providers should emphasize critical steps and common mistakes to ensure that patients receive maximum benefit from their medication.

Multiple studies have investigated the relationship between androgenetic alopecia and cardiovascular disease, including studies that have identified elevated rates of cardiovascular disease in patients with vertex hair loss, vertex and frontal hair loss, early onset hair loss and rapidly progressive hair loss. In addition, increased risks for hypertension, excess weight, abnormal lipids, insulin resistance, carotid atheromatosis and death from diabetes or heart disease have been reported in this population. Studies investigating an association between androgenetic alopecia and metabolic syndrome have yielded conflicting findings. Distinct guidelines for the detection and prevention of cardiovascular disease in individuals with androgenetic alopecia have not been established. In addition to the traditional risk factors for developing cardiovascular disease, included in the definition of the metabolic syndrome, several skin diseases have recently been shown to be markers of conditions relating to the patient’s overall health. Physicians should be aware of the possible connection between relatively frequent skin diseases, such as psoriasis and hair growth disruptions, including androgenetic alopecia and female pattern hair loss and cardiovascular disease. This review is concentrated on the association between insulin resistance, type 2 diabetes, abdominal fat, cardiovascular disease and hair growth disruptions as an early indicator of these underlying conditions. We have investigated the importance of robust primary clinical treatment measures to address the manifestation of hair loss due to a disruption caused by metabolic syndrome as an effective means to alleviate further stress induced hair loss, which can exacerbate the underlying cause.

The Enterprise Radiation Forest (ERF) study was initially introduced as a topic of discussion at the Institute of Forest Genetics, USDA, USFS, in the late 1960s. During that period, a program was endorsed for investigating the impacts of radiation on the forest ecosystem. The rationale for this was to facilitate the prediction of potential outcomes in the occurrence of a nuclear disaster. The research location was situated within the forested lands in Enterprise of Oneida County, Wisconsin, United States. The radiation source in question was a 10,000 curie source of Cesium-137, characterized by a halflife of 33 years. Furthermore, a study concerning lichens was also carried out, the data, photographs, and micrographs were meticulously gathered to illustrate the pre-irradiation activity of the species. This subject holds significant value for dissemination among peers in the scientific community, particularly considering the resilience exhibited by natural ecosystems in response to varying levels of radiation. The information is reviewed with the objective of the entire program to ascertain the potential consequences for a northern forest ecosystem in the event of a nuclear disaster, in addition to the two publications from the Atomic Energy Commission.

The effects of storage of Ogbona seed flour (Irivingia gabonensis and Irivingia excelsa), at ambient condition (30±20C, 65-74% RH) for 0-4 months on some physical characteristics were investigated. The samples were subjected to storage in air tight polyethylene bags for up to four months. Samples were removed at intervals of 0, 1, 2, 3 and 4 months for analysis. The chemical: proximate constituents, free-fatty acids and peroxide values; selected functional properties: water/oil absorption capacity, foam capacity and viscosity and sensory attributes of the samples were investigated. The result shows that there was no observable change in the chemical composition, selected functional and sensory properties of the two varieties of Ogbona seed flours when stored up to two months but decreased from third to fourth month during storage at ambient temperature. Therefore, storage at ambient temperature (30±20C, 65-74% RH) could extend the shelf life of the samples for up to two months in air-tight polyethylene bags of 0.7mm thickness without losing its quality characteristics.

Background information: Cultural practices play an important role on the development of pathogens (Datnoff, et al. 2007). In this context, several authors have been interested in studying the effects of mineral nutrition on the resistance of vegetables and fruits to fungi during storage, especially nitrogen.The purpose of the study: In this work we tested the effects of three contrasted regimes of nitrogen supply, with nitrate concentrations in the nutrient solutions of 2 mM (low), 10 mM (normal) and 20 mM (high) on the susceptibility of Lactuca sativa L towards Botrytis cinerea (BC87) and Sclerotinia minor (SM) during storage.Once harvested, the outerleaves of the plants derived from the three nitrogen regimes were inoculated with either Botrytis cinerea (BC87) or Sclerotinia minor (SM). Data showed that the resistance to this two pathogens increase when plants were developed under low nitrogen concentration. This resistance observed is correlated with low values in oxidative stress indicators (MDA and H2O2) and high values in total phenols.

The quality characteristics of selected black gram varieties viz., VBN 5, VBN 7, ADT 3, T9 and CO 6 and were evaluated for their suitability for the preparation of thick pancake. The foaming stability and foaming capacity were found to be maximum in VBN 5, CO 6 and T9. Maximum rise in volume was recorded in CO 6 (149 ml) followed by VBN 5 (148 ml) and T9 (147 ml) which is an indication good quality of thick pancake. Thick pancake prepared using 5 black gram varieties were analyzed for the physicochemical and microbial load. The texture profile viz., springiness, cohesiveness, chewiness and gumminess was evaluated for VBN 5, CO 6, T9 and VBN 7 respectively. The protein content was higher in thick pancake prepared from VBN 5 (25.47/100 g) compared to CO 6 (24.66 g/100g). Among the selected varieties, CO 6, T9 and VBN 5 had good batter content, texture, and microstructure and were found to be most suitable for thick pancake preparation.

Background: Sarcoidosis is a systemic granulomatous inflammatory disease that is associated with inflammatory eye manifestations such as uveitis, cystoid macular edema, and retinal vasculitis. Although Corticosteroids (CS) have traditionally been the mainstay of treatment, there is a clinical need and growing interest in exploring alternative therapeutic options for patients who are refractory to or intolerant of CS or require long-term steroid-sparing agents. Purpose: This case series aims to describe the effectiveness of adalimumab, an anti-tumor necrosis factor (TNF)-α monoclonal antibody, in the management of complex sarcoidosis-related inflammatory eye disease via reduction in CS dosage and ocular exam findings before and after initiation of adalimumab therapy.Method: A retrospective chart review of patients between 2010 and 2023 seen at our academic center’s rheumatology and eye clinics was conducted, with 5 patients meeting the inclusion criteria. Results: Most patients were able to lower, discontinue, or remain off oral CS, while all 5 patients demonstrated a reduction in uveitis activity, Cystoid Macular Edema (CME), and/or retinal vasculitis. Conclusion: These findings suggest a potential role for adalimumab as an effective and safe therapeutic option in the management of complex sarcoidosis-related inflammatory eye disease.

Since the advent of antibiotics, lateral sinus thrombosis is an infrequent complication of otitis media. Lateral sinus thrombosis may occur by thrombophlebitis or penetration by offending pathogens through the dura of middle and posterior cranial fossae. We present a case of right-sided sigmoid and transverse venous sinus thrombosis as a rare complication of chronic suppurative otitis media in an adult. We discuss the patient’s imaging, management and relevant literature to offer clinical recommendations. A 39-year-old woman presented with headache, neck pain, vomiting, fever and photophobia with a tender right mastoid on examination. Computerised Tomography, Magnetic Resonance Imaging and Magnetic Resonance Venogram of the head revealed complete opacification of the right mastoid air cells and middle ear, with absent flow void in the right transverse and sigmoid sinus, consistent with thrombosis. After discussion with neurosurgery, she was commenced on anticoagulants. The patient was readmitted with right otalgia and otorrhea refractory to medical treatment, and ultimately underwent right mastoid exploration. Conclusion: Lateral sinus thrombosis may occur with other intracranial or extracranial complications of otitis media. Clinicians should approach any complication of otitis media with vigilance as antibiotics may mask some signs and symptoms of mastoiditis, which can progress to otogenic brain abscess.
