Informal Care Time and Costs of Dementia Care in Benin (West Africa).

BACKGROUND: Dementia is a growing global health challenge, with significant socioeconomic implications. This study examined the informal care duration and related costs along with the total cost of care for older individuals with dementia in Benin, West Africa, providing insights into a region with limited dementia research. METHODS: We conducted a cost-of-illness study in Benin. Both hospital and community recruitments were used to enroll adults aged ≥60 years and their primary caregivers. Structured questionnaire and validated tools were used to collect the demographic, clinical, healthcare resource utilization data as well as informal care duration. Replacement costs approach was performed to valuate informal care time. Official exchange rates from the World Bank were used to convert costs from local currency to purchasing power parities dollars (PPP$). RESULTS: Data from 135 individuals with varying dementia stages revealed that dementia places substantial caregiving demands, predominantly on women who provide up to 8 h of daily care. In 2021, the mean annual cost of dementia care was estimated to be PPP$ 2,399.66 ± 2,057.07. Informal care represented a significant portion of dementia expenses, up to 92% of the total care costs in this study. DISCUSSION: Policy interventions are urgently needed to address the dementia care challenges in Benin, especially because economic transitions and educational advancements may reduce the availability of informal caregivers. This emphasizes the vital role of informal caregivers and underscores the need of implementing dementia policies to support families facing the evolving challenges of dementia care.

Ultrasound-detected tibial artery calcification as a marker of cardiovascular and lower-limb risk in asymptomatic patients with type-2 diabetes.

BACKGROUND: Medial arterial calcification (MAC) is a vascular disease distinct from atherosclerosis. Recently, several studies have demonstrated that MAC is an important marker of cardiovascular events. We aim to assess the presence of MAC during ultrasound screening of lower-limb vasculature and its association with both cardiovascular (CV) and lower-limb events in patients with type-2 diabetes. METHODS: A retrospective cohort study was conducted on 1119 patients with type-2 diabetes free from CV disease. A CV work-up, including vascular ultrasound, was performed for each patient. The presence of MAC was assessed on posterior tibial arteries and ankle-brachial index (ABI) was measured. Major acute CV events (MACEs) and lower-limb events (MALEs) were recorded as a composite endpoint for a 5-year period. RESULTS: We identified MAC among 212 (18.9%) patients. The independent determinants of MAC were age and diabetic retinopathy. Over a period of 5 years, 125 MACEs and 22 MALEs occurred. MAC was significantly associated with the composite outcome MACE + MALE (HR = 1.94; 95% CI: 1.23, 3.08, p = 0.005) or with MACE (HR = 1.85; 95% CI: 1.16, 2.95, p = 0.010). Adjusted for ABI and diabetic foot wound, MAC remained a determinant of MALE (HR = 5.49; 95% CI: 2.19, 13.76, p < 0.001). Considering each ABI group, MAC was associated with both MACE and MALE in the normal ABI group. CONCLUSIONS: Ultrasound-detected MAC on tibial arteries seems to be a determinant of both CV and lower-limb events, independent from ABI. MAC helps to refine the CV risk in patients with normal ABI.

Costs of Dementia in Low- And Middle-Income Countries: A Systematic Review.

BACKGROUND: The proportion of people living with dementia in low- and middle-income countries (LMICs) is expected to reach 71% by 2050. Appraising the economic burden of the disease may contribute to strategic policy planning. OBJECTIVE: To review studies conducted on the costs of dementia in LMICs, describe their methodology and summarize available costs estimates. METHODS: Systematic review, including a search of health, economics, and social science bibliographic databases. No date or language restrictions were applied. All studies with a direct measure of the costs of dementia care were included. RESULTS: Of the 6,843 publications reviewed, 17 studies from 11 LMICs were included. Costs of dementia tended to increase with the severity of the disease. Medical costs were greater in the mild stage, while social and informal care costs were highest in the moderate and severe stages. Annual cost estimates per patient ranged from PPP$131.0 to PPP$31,188.8 for medical costs; from PPP$16.1 to PPP$10,581.7 for social care services and from PPP$140.0 to PPP$25,798 for informal care. Overall, dementia care can cost from PPP$479.0 to PPP$66,143.6 per year for a single patient. CONCLUSION: Few studies have been conducted on the costs of dementia in LMICs, and none so far in Africa. There seems to be a need to provide accurate data on the burden of disease in these countries to guide public health policies in the coming decades.

Vascular ultrasound for cardiovascular risk stratification in asymptomatic patients with type-2 diabetes.

AIMS: To identify new independent vascular markers to predict cardiovascular events in patients with type-2 diabetes (T2D), and their incremental value compared to the Swedish National Diabetes Register (NDR) risk score. METHODS: A retrospective cohort study was conducted on 1332 asymptomatic patients with T2D, free from prior CV event, assessed for a cardiovascular work-up, including Duplex ultrasonography to detect plaque on carotid and femoral arteries. The extent of atherosclerosis was rated as atherosclerosis burden score (ABS). Patients were followed up to 5 years and the occurrence of cardiovascular events recorded. RESULTS: A total of 82 patients (6.2%) experienced a cardiovascular event, including 34 (2.6%) myocardial infarction, 18 (1.4%) cardiac revascularisation and 17 (1.3%) stroke. The independent determinants of these events were male sex (HR = 1.81 [1.13-2.88], p = 0.013) and ABS ≥ 2 (HR = 1.98 [1.21-3.25], p = 0.007). The NDR risk score performed poorly to predict cardiovascular events (area under the curve = 0.56 [0.49-0.63], p = 0.11), whereas screening for atherosclerotic plaques provided significant incremental prognostic value over the NDR score (model χ2 increase: +231%, p = 0.002). CONCLUSION: Duplex ultrasonography to screen for atherosclerotic plaques improve the estimation of cardiovascular prognosis on top of clinical data and could be routinely used to improve cardiovascular risk stratification.
