Ischemic stroke as the first clinical manifestation of an initially undiagnosed case of Takayasu arteritis in a young woman from Ethiopia: A case report.

Takayasu arteritis (TAK) is a rare large-vessel vasculitis of unknown etiology that leads to arterial wall thickening, stenosis, and occlusion, which may complicate cerebrovascular ischemic events. Ischemic stroke is a potentially devastating complication of TAK at a young age, but the occurrence is still rarely reported in Ethiopia. Although it occurs late in the course of the condition, it may be the initial presentation and suggest an unfavorable prognosis. Herein, we address the case of a 25-year-old woman who presented to a university hospital while on follow-up after 2 years of stroke with deterioration in clinical symptoms, absent brachial artery pulses, and unrecordable blood pressure in both arms. At the time of admission in 2021, the contrast brain computed tomography scan revealed an ischemic infarction in the right middle cerebral artery territory. However, the etiology of the stroke could not be defined at that time due to ambiguity in the clinical picture and the inability of clinicians to incorporate TAK into the differential diagnosis, resulting in a delay in the early diagnosis of the case. Two years later, in 2023, she underwent computed tomography angiography and was diagnosed to have TAK based on American College of Rheumatology criteria, with Numano type IIb angiographic extent of disease, ischemic stroke, and stage II systemic hypertension. The patient was treated by a field of experts. This case highlights the need to consider TAK in the differential diagnosis of stroke in young patients in the absence of traditional risk factors; appropriate tests should be performed to confirm or rule out this diagnosis, and management should be modified accordingly.

Correlates of serum estradiol concentration among postmenopausal women in Ilorin, North-Central Nigeria.

OBJECTIVES: There are limited data on the associated factors of circulating endogenous estradiol among Nigerian postmenopausal women. The main objective of this study is to assess the relationship between serum estradiol levels and some menstrual, clinical, and sociodemographic factors in postmenopausal women attending a family medicine clinic in Nigeria. METHODS: This was a hospital-based cross-sectional study involving 372 postmenopausal women. Sociodemographic, menstrual, and clinical data of the participants were collected, and their serum estradiol concentrations were assayed. The collected data were analyzed using IBM SPSS version 21 statistical software. A χ2 test of association and logistic regression analysis were done to identify significant correlates of serum estradiol concentration among the participants. RESULTS: The mean ages at menarche and menopause among the participants were 15.6 and 48.1 years respectively. Approximately half of them (51.1%) were receiving chronic medical care for systemic hypertension and/or diabetes. The mean estradiol concentration of the participants in the study was 20.69 pg/mL. The participants' marital status and clinical presentation pattern (chronic vs others) were found to have statistically significant associations with their serum estradiol concentration; P = 0.048 and P = 0.001, respectively. Logistic regression analysis revealed that only the clinical presentation pattern had a significant relationship with serum estradiol concentration among the participants ( P = 0.002). CONCLUSION: Of all the studied factors, the only significant correlate of low serum estradiol concentration found in this study was chronic medical care presentation for hypertension and/or diabetes.

COVID-19 vaccination knowledge, attitudes and practices among the general population of Romania during the third wave of COVID-19 pandemic.

Objective: Romania began its COVID-19 immunization programme with approved vaccinations in three stages, as follows: The first step of vaccination is for health and social professionals, the second stage is for high-risk persons and the third stage is for the remainder of the general public. This study aims at assessment of knowledge, attitude and practice towards COVID-19 and vaccination against COVID-19 in the Romanian population during the third wave of the pandemic. Methods: This cross-sectional study was based on a Bosnian and Herzegovinian study on COVID-19 vaccination during the country's third wave of COVID-19 pandemic. Results: Our study sample, dominantly female (629; 61.0%), with a bachelor's degree (734; 71.2%), either single (539; 52.3%) or in a relationship (363; 35.2%), engaged in intellectual labour (910; 88.3%) and living in an urban environment (874; 84.8%) with a mean age of 25.07 ± 8.21 years, 294 (28.5%) people with COVID-19 symptoms and 86 (8.3%) were tested COVID-19 positive, had a mean knowledge score of 16.38 ± 4.0 with correct answer rates on questions ranging from 30.1% to 88.2%. Being single (odds ratio = 3.92, p = 0.029) or in a relationship (odds ratio = 3.79, p = 0.034), having a bachelor's degree and higher (odds ratio = 1.61, p = 0.006) and being COVID-19 tested (odds ratio = 1.82, p < 0.001) were associated with higher knowledge test scores. Our sample had relatively optimistic attitudes towards final COVID-19 disease containment (712; 69.1%) and vaccination programmes (679; 65.9%). The majority of the sample followed socio-epidemiological measures and did not visit places of mass social gatherings (666; 64.1%) and wore masks (992; 95.7%) while being outside their home. In terms of vaccination rates, 382 (37.0%) of the individuals were presently immunized against COVID-19. Higher knowledge test scores (>15 points) (odds ratio = 1.66, p = 0.002) and positive attitudes of this study (odds ratio = 1.59, p = 0.001, odds ratio = 4.16, p < 0.001) were identified as independent predictors for vaccinating against COVID-19. Conclusion: Romanian citizens have had good knowledge, optimistic attitudes and appropriate practices towards COVID-19 vaccination during the third wave of COVID-19 outbreak in the country. Higher knowledge regarding the disease and vaccination against it not only increased attitudes towards the end of the pandemic, but also increased the willingness to be vaccinated and to avoid infection risk factors.

Risk factors for Brucellosis and knowledge-attitude practice among pastoralists in Afar and Somali regions of Ethiopia.

BACKGROUND: Brucellosis is a neglected bacterial zoonotic disease with substantial economic impact on households. Pastoral communities are a potential risk group due to their way of life being closely interlinked with their large livestock herds. METHODOLOGY: A semi-structured questionnaire survey was conducted in households in the pastoral Afar and Somali (SRS) regions. All households had people and animals serologically tested for brucellosis. Questions were related to husbandry, consumption habits, and knowledge-attitude-practice towards the disease and zoonoses. Descriptive statistics and logistic analysis were performed to assess potential risk factors for having households with positive humans and/or animals. RESULT: 647 households were included in the survey. Herd brucellosis prevalence was 40.3 % (15.9-86.3 % in Afar; 4-72.2 % in SRS). Over half (56.3 %) of the households in Afar and 41.8 % in SRS had at least one human reactor. Nearly a quarter of the households (22.8 %), recalled abortions in goats in the last 12 months, whereas 52.5 % and 50.3 % recalled stillborn in all species and membrane retentions respectively. All respondents drank raw milk and discarded animal afterbirths in the direct surroundings with minimal protection. Risk factors for animal reactors were goat herd size, and goat abortion. There was no identified risk factor for having human reactors in households. None of the households knew about brucellosis. CONCLUSION: Although being endemic in Afar and SRS, Brucellosis is not known by the pastoralists. Brucellosis control programs will have to be tailored to the pastoral context, accounting for their mobility, large, multi-species herds and habits.

Pattern and Predictors of Sexual Activity among Postmenopausal Women Attending a Family Medicine Clinic in Ilorin, North-Central Nigeria.

OBJECTIVES: Sexual activity tends to decline with age and is greatly impacted in postmenopausal women. This study aimed to describe the sexual activity pattern among postmenopausal Nigerian women and also detect socio-demographic and menopause-related predictors of their sexual activity. METHODS: In this hospital-based cross-sectional study, 357 postmenopausal women between 45-60 years participated. Data was collected using the sexual activity questionnaire and a socio-demographic questionnaire developed by the authors. RESULTS: The prevalence of sexual inactivity among the participants was 60%. This was attributed mainly to the unavailability of male partners (50.5%) and negative menopause-related sociocultural beliefs (23.8%). Among sexually active participants, 83.2% of them reported having pleasurable experiences and 53.8% of them reported no associated sexual discomfort. Only being in a marital relationship was found to be a statistically significant predictor of sexual activity among the participants (regression coefficient = 3.125, degree of freedom = 1, P < 0.0001). CONCLUSIONS: We reported a high prevalence of sexual inactivity among the participants; the most important reasons given were the unavailability of their husbands and the belief that sexual intercourse was taboo during the postmenopausal period. The study also provided positive evidence for the importance of marriage for sexual activity among the participants.

Distal symmetrical polyneuropathy detected by vibration perception threshold among adults with and without diabetes attending a general outpatient clinic in Ilorin, Nigeria

The aim of this study is to compare the prevalence, severity, and symptoms of Distal Symmetrical Polyneuropathy (DSP) among adult patients with diabetes and those without diabetes in a primary care clinic. It was a cross-sectional comparative study involving 72 adults of between 40-60 years of age living with diabetes and 72 age-matched adults without diabetes. DSP was assessed with a biothesiometer device, and data analysis was performed using the SPSS Version 21 statistical software. The overall prevalence of neuropathy among the participants was 68.1% for those living with diabetes and 38.9% for the other group. Furthermore, 22.3% of the diabetes group had severe neuropathy compared with 8.3% of the other group. These differences were found to be statistically significant with p=0.001 (df = 2, X2 = 14.07). We reported higher prevalence and severity of DSP in those living with diabetes. We also found significant association between high VPT (≥25V) and presence of neuropathic symptoms thereby enhancing the use of the biothesiometer device in the diagnosis of adults with DSP in the primary care setting.

Integrated human-animal sero-surveillance of Brucellosis in the pastoral Afar and Somali regions of Ethiopia.

BACKGROUND: Brucellosis is widespread in Ethiopia with variable reported prevalence depending on the geographical area, husbandry practices and animal species. However, there is limited information on the disease prevalence amongst pastoral communities, whose life is intricately linked with their livestock. METHODOLOGY: We conducted an integrated human-animal brucellosis sero-surveillance study in two adjacent pastoral regions, Afar and Somali region (SRS). This cross-sectional study included 13 woredas (districts) and 650 households. Blood samples were collected from people and livestock species (cattle, camel, goats and sheep). Sera were analyzed with C-ELISA for camels and shoats (sheep and goats), with I-ELISA for cattle and IgG ELISA for humans. Descriptive and inferential statistics analyses were performed. RESULTS: A total of 5469 sera were tested by ELISA. Prevalence of livestock was 9.0% in Afar and 8.6% in SRS (ranging from 0.6 to 20.2% at woreda level). In humans, prevalence was 48.3% in Afar and 34.9% in SRS (ranging from 0.0 to 74.5% at woreda level). 68.4% of all households in Afar and 57.5% of households in SRS had at least one animal reactor. Overall, 4.1% of animals had a history of abortion. The proportion of animals with abortion history was higher in seropositive animals than in seronegative animals. Risk factor analysis showed that female animals were significantly at higher risk of being reactors (p = 0.013). Among the species, cattle had the least risk of being reactors (p = 0.014). In humans, there was a clear regional association of disease prevalence (p = 0.002). The older the people, the highest the odds of being seropositive. CONCLUSION: Brucellosis is widespread in humans and animals in pastoral communities of Afar and SRS with the existence of geographical hotspots. No clear association was seen between human and particular livestock species prevalence, hence there was no indication as whether B. abortus or B. melitensis are circulating in these areas, which warrants further molecular research prior to embarking on a national control programs. Such programs will need to be tailored to the pastoral context.
