Strategies to strengthen COVID-19 vaccine uptake and improve vaccine equity in U.S. Territories and Freely Associated States during the first six months of vaccine rollout.

The eight U.S. territories and freely associated states (TFAS) have historically faced unique social and structural barriers in the implementation of vaccination programs due to geographic remoteness, a high prevalence of socioeconomic disparities, increasing prevalence of natural disasters, limited vaccine providers and clinics, difficulties with procurement and shipping, and difficulty tracking highly mobile populations. In the months leading up to emergency authorizations for the use of COVID-19 vaccines, the TFAS developed tailored vaccination strategies to ensure that key at-risk populations received timely vaccination, and successfully implemented these strategies during the first six months of the vaccine rollout. Subject matter experts supporting the Centers for Disease Control and Prevention's COVID-19 Response recognized the unique historical, geographic, social, and cultural dynamics for residents in the TFAS and worked with partners to prevent, detect, and respond to the pandemic in these jurisdictions. As a result of innovative partnerships and vaccine distribution strategies, vaccine equity was improved in the TFAS during the COVID-19 vaccine rollout.

Assessment of COVID-19 Vaccination Practices for 16 Vaccination Providers in Puerto Rico, 2021.

OBJECTIVE: To assess COVID-19 vaccine providers' adherence to best practices and identify knowledge and practice gaps to guide corrective actions and retraining activities in Puerto Rico. METHODS: A CDC supportive evaluation tool was modified to collect information on vaccine storage, handling, preparation, administration, and post-vaccination care. Assessment visits to COVID-19 vaccine providers in Puerto Rico were conducted a month after the availability of COVID-19 vaccines in the island. RESULTS: A total 16 vaccine providers were visited, 12 (75%) administering Pfizer-BioNTech vaccine and 4 (25%) administering Moderna vaccine. All providers adhered to correct handling practices after vaccine thawing. Required resources for managing anaphylaxis on site were available in all sites. Few instances of incorrect use of retractable-needle syringes, unapproved temperature monitoring devices, and lack of recorded temperature data were observed. Corrective actions were taken during the evaluation visit. CONCLUSION: No major deficiencies that could jeopardize vaccine viability or patient safety were found. The use of a supportive evaluation tool during assessment visits is helpful to determine needs for vaccine providers retraining and to continue the safe administration of COVID-19 vaccines in Puerto Rico.

Tuberculosis among homeless population from Medellín, Colombia: associated mental disorders and socio-demographic characteristics.

Homeless people are highly susceptible to tuberculosis. It has been suggested that this population have high rates of mental disorders associated with tuberculosis. We assessed tuberculosis incidence, its transmission patterns and association with socio-demographic factors and mental disorders in Colombian homeless people. Prospective study which socio-demographic characteristics and mental disorders were assessed through interviews. Sputa from patients with respiratory symptoms were processed and clinical isolates analyzed by IS6110-RFLP. Multivariate analysis performed by logistic regression model. From 426 homeless studied, tuberculosis incidence found was 7.9 %. 44 % of isolates were clustering. It was found high risk of having tuberculosis associated with income from drugs trade (OR: 3.40 [95 % CI: 1.28-9.05]), dysthymia (OR: 2.54 [95 % CI: 1.10-5.86]) and receiving food from other homeless (OR: 2.47 [95 % CI: 1.16-5.25]). Tuberculosis incidence and degree of transmission are high in homeless studied. Implementing programs to better control tuberculosis among homeless population must consider socio-demographic factors and mental disorders associated with the disease.

Morbilidad asociada a la edad gestacional en neonatos prematuros tardíos / Gestational age-associated morbidity in late preterm neonates

Objetivo: comparar la morbilidad a corto plazo, intervenciones, estancia hospitalaria y los costos de prematuros de 34 semanas, con prematuros mayores a 34 semanas (35-36 semanas), hospitalizados en la Unidad de Cuidados Intensivos Neonatales de la Fundación Hospital San José de Buga, Colombia, entre el 19 de septiembre de 2005 y el 18 de septiembre de 2011. Métodos: estudio de cohorte retrospectivo, con 40 recién nacidos de 34 semanas de gestación y 129 de 35-36. Se evaluaron factores materno-neonatales y terapias aplicadas. El análisis incluyó estadísticas descriptivas y análisis bivariado. Para las asociaciones se empleó el riesgo relativo con su intervalo de confianza de 95 %, así como la prueba de chi² de Pearson de independencia. Resultados: se hallaron morbilidades respiratorias en el 32,5 %, ictericia en el 29 %, morbilidades gastrointestinales en el 13,6 %, metabólicas en el 13,6 %, cardiacas en el 1,8 %, hematológicas en el 1,2 %, e hipotermia y sepsis también en el 1,2 %. La falla renal se produjo en el 0,6 %, sin diferencias estadísticas entre los 2 grupos. Se halló diferencia estadísticamente significativa (p< 0,05) para tiempo de ayuno (> 2 días), administración de nutrición parenteral, horas de oxigenoterapia (> 2 y 5 días), horas de ventilación mecánica y estancia prolongada (> 7 días), y fueron los neonatos de 34 semanas los más afectados. El peso, talla y perímetro cefálico al nacer y egreso, fueron menores en aquellos de 34 semanas, mientras el retardo del crecimiento intrauterino fue superior en los de 35 y 36 semanas (26,4 vs. 7,5 %; RR: 1,3; IC 95 %: 1,1-1,5; p< 0,05). La atención hospitalaria de los neonatos de 34 semanas, resulta, por tanto, ser 1,6 y 0,6 veces más costosa en dinero, que la de los de 35 y 36 semanas. Conclusiones: el prematuro tardío debe considerarse inmaduro y con riesgo de morbilidad y mortalidad. Estos tienen gran incidencia de ictericia, morbilidad respiratoria, gastrointestinal y metabólica. Pero, los de 34 semanas, comparados con los de 35 y 36 semanas, requieren más intervenciones.

Objective: to compare the short-term morbidity, the number of interventions, the length of stay at hospital and the incurred costs between 34-weeks neonates and over-34 weeks newborns, who had been admitted to the neonatal intensive care units of Fundacion Hospital San Jose de Buga in Colombia from September 19th 2005 to September 18th 2011. Methods: retrospective cohort study in forty 34-weeks newborns and one hundred twenty nine 35-36 weeks neonates. Maternal and neonatal factors as well as applied therapies were evaluated. The analysis covered summary statistics and bivariate analysis. For finding association, the relative risk with 95 % confidence interval, and the Pearson's chi square test of independence were used. Results: respiratory morbidity was found in 32.5 % of patients, jaundice in 29 %, gastrointestinal morbidity in 13.6 %, metabolic morbidity in 13.6 %, cardiac morbidity in 1.8 %, hematological morbidity in 1.2 % and hypothermia and sepsis were seen in 1.2 % of patients. Renal failure affected 0.6 % of neonates, without statistical difference between the groups. There was statistically significant difference (p< 0,05) for fasting time (over 2 days), parenteral nutrition and time of oxygen therapy (more than 2 and 5 days, respectively), time of mechanical ventilation and long stays at hospital (over 7 days); the 34-weeks neonates were the most affected in terms of morbidity. Weight, size and head perimeter figures at birth and at discharge from the hospital were lower in the 34 weeks group, whereas the delayed intrauterine growth was greater in the 35 and 36 weeks neonates (26,4 vs. 7,5 %; RR: 1,3; IC 95 %: 1,1-1,5; p< 0,05). The care of 34 week neonates at hospital is, therefore, 1.6 and 0.6 times more expensive than that of 35 and 36-weeks newborns. Conclusions: the late preterm infant should be considered as immature with morbidity and mortality risks. The incidence of jaundice, respiratory, gastrointestinal and metabolic morbidities is high; however, the 34-week newborns require more interventions than the 35 and 36 weeks neonates.
