RESUMO
Vaccination has proven to be one of the most effective strategies against the COVID-19 pandemic. Several studies have evaluated and confirmed its effectiveness in different populations, particularly in reducing severe outcomes such as hospitalization and death. Some studies have investigated the effectiveness of vaccination against the infection, identifying the need for booster doses. This study aimed to explore the effectiveness of the vaccination schedule on the probability of infection in a sample of Colombian patients during the fourth wave of the COVID-19 pandemic, which was associated with the emergence and predominance of the Omicron variant. A cross-sectional study was conducted on individuals who underwent RT-PCR testing for COVID-19 detection in a dedicated laboratory in Bogotá, Colombia, between 30 December 2021 and 7 February 2022. A total of 1468 subjects was included in the study, of whom 36.6% (n = 538) had a positive PCR test for COVID-19. The comparison between fully vaccinated individuals with a booster dose and those without the booster dose revealed a 28% reduction in the odds of infection (OR = 0.719 CI 0.531-0.971). Age (OR = 1.009 CI 1.001-1.018) and low economic status (OR = 1.812 CI 1.416-2.319) were associated with an increased risk of infection. These findings suggest the need for a booster vaccination in the general population to improve the prevention rates of SARS-CoV-2 infection and mitigate severe outcomes.
RESUMO
BACKGROUND: Malnutrition among inflammatory bowel disease (IBD) subjects is well documented in literature and may emerge from factors including inadequate dietary intake, malabsorption and disease activity. The aim of this study was to complete a comprehensive nutrition assessment and explore what possibilities may help bring a better quality of life for IBD subjects. METHODS: Nutritional status based on biochemical tests, body composition and body mass index (BMI). Food intake was assessed by an alternate 3-day food record and the adequacy of intake was evaluated according to national and international references. Clinical disease activity was evaluated by the Harvey-Bradshaw index and CRP levels. RESULTS: The study included 217 patients and 65 controls, where 54.4% of these patients were classified as normal weight with a mean BMI lower than controls (23.8 ± 4.9 versus 26.9 ± 4.8 kg/m2, P = 0.02). Patients with disease activity showed more overweight and obesity than patients with controlled disease. Vitamin B12 deficiency was present in 19% of Crohn's disease (CD), mainly in patients with ileal commitment and small bowel resections. Anemia was present in 21.7% of patients, being more common in patients with active disease (25%) and bowel resection (23%). Regarding calorie intake (EI), CD group ingested more than controls (1986.3 ± 595.9 kcal versus 1701.8 ± 478.9 kcal; P = 0.003). CONCLUSIONS: CD patients presented micronutrient deficiency when compared with controls, explained for other reasons than intake restrictions. Also, fat excess might have contributed to disease burden as continuously reported in the literature.
RESUMO
ABSTRACT Monalonion velezangeli Carvalho and Costa (Hemiptera: Miridae) is a polyphagous plant bug recognized as one of the most important pest species of coffee and avocado in rural regions of Colombia. M. velezangeli is reported for the first time in green urban areas in the high Andean city of Bogotá (Colombia). Specimens were collected on eight species of urban trees planted in the city, of which five represent new plant associations for M. velezangeli. The plant species Schinus molle L. (Anacardiaceae) is for the first time reported as new host plant damaged by M. velezangeli under urban conditions.
RESUMEN Monalonion velezangeli Carvalho and Costa (Hemiptera: Miridae) es un mírido polífago reconocido como una de las especies plaga más importantes del café y el aguacate en regiones rurales de Colombia. M. velezangeli es reportado por primera vez en áreas verdes urbanas en la cordillera de los Andes en la ciudad de Bogotá (Colombia). Los especímenes fueron recolectados en ocho especies de árboles plantados en la ciudad, de los cuales cinco representan nuevas asociaciones de M. velezangeli. La especie Schinus molle L. (Anacardiaceae) es por primera vez reportada como nueva planta hospedera afectada por M. velezangeli bajo las condiciones urbanas.
