Assessment of the Field Utility of a Rapid Point-of-Care Test for SARS-CoV-2 Antibodies in a Household Cohort.

Point-of-care (POC) tests to detect SARS-CoV-2 antibodies offer quick assessment of serostatus after natural infection or vaccination. We compared the field performance of the BioMedomics COVID-19 IgM/IgG Rapid Antibody Test against an ELISA in 303 participants enrolled in a SARS-CoV-2 household cohort study. The rapid antibody test was easily implemented with consistent interpretation across 14 users in a variety of field settings. Compared with ELISA, detection of seroconversion lagged by 5 to 10 days. However, it retained a sensitivity of 90% (160/177, 95% confidence interval [CI] 85-94%) and specificity of 100% (43/43, 95% CI 92-100%) for those tested 3 to 5 weeks after symptom onset. Sensitivity was diminished among those with asymptomatic infection (74% [14/19], 95% CI 49-91%) and early in infection (45% [29/64], 95% CI 33-58%). When used appropriately, rapid antibody tests offer a convenient way to detect symptomatic infections during convalescence.

Caregiver Burden among Caregivers of Patient Undergoing Hemodialysis in Tertiary Care Center : A Descriptive Cross-sectional Study.

INTRODUCTION: Chronic kidney disease affects almost all aspects of life of the patients and caregivers. Dialysis is a common treatment modality for chronic renal failure. The caregivers of patients undergoing hemodialysis bear the emotional and psychological stress of having a chronically ill patient. The physical and psychological distress, limitations in personal and social activities, loss of freedom, financial limitations directly or indirectly affect the level of burden among caregivers. This study aims to study the level of burden among caregivers of patient undergoing hemodialysis. METHODS: A descriptive cross-sectional study among 123 caregivers giving care to hemodialysis patients for at least 3 months at Teaching Hospitals, Chitwan was carried out using simple random sampling technique. Level of burden was evaluated using the burden questionnaire (Zarit Burden Interview). RESULTS: The study revealed that 60 (48.78%) had mild to moderate, 53 (43.08%) had moderate to severe. The median scores for burden among the caregivers was (39.30±11.68) with 44.65%. CONCLUSIONS: Coping Strategies, social support, support interventions has greater impact on caregivers in achieving their roles in caring the patients and increases the capability to cope effectively with the patient's condition.
