    BACKGROUND: The use of respiratory devices can mitigate the spread of diseases such as COVID-19 in community settings. We aimed to determine the effectiveness of closed face shields with surgical face masks to prevent SARS-CoV-2 transmission in working adults during the COVID-19 pandemic in Bogotá, Colombia. METHODS: An open-label non-inferiority randomized controlled trial that randomly assigned participants to one of two groups: the intervention group was instructed to wear closed face shields with surgical face masks, and the active control group was instructed to wear only surgical face masks. The primary outcome was a positive reverse transcription polymerase chain reaction test, IgG/IgM antibody test for SARS-CoV-2 detection, or both during and at the end of the follow-up period of 21 days. The non-inferiority limit was established at - 5%. RESULTS: A total of 316 participants were randomized, 160 participants were assigned to the intervention group and 156 to the active control group. In total, 141 (88.1%) participants in the intervention group and 142 (91.0%) in the active control group completed the follow-up. PRIMARY OUTCOME: a positive SARS-CoV-2 test result was identified in one (0.71%) participant in the intervention group and three (2.1%) in the active control group. In the intention-to-treat analysis, the absolute risk difference was - 1.40% (95% CI [- 4.14%, 1.33%]), and in the per-protocol analysis, the risk difference was - 1.40% (95% CI [- 4.20, 1.40]), indicating non-inferiority of the closed face shield plus face mask (did not cross the non-inferiority limit). CONCLUSIONS: The use of closed face shields and surgical face masks was non-inferior to the surgical face mask alone in the prevention of SARS-CoV-2 infection in highly exposed groups. Settings with highly active viral transmission and conditions such as poor ventilation, crowding, and high mobility due to occupation may benefit from the combined use of masks and closed face shields to mitigate SARS-CoV-2 transmission.

    Estrategias de intercambio de conocimiento entre profesionales de la salud, parteras y trabajadores comunitarios para el mejoramiento de la salud materna a nivel nacional e internacional: revision sistematica de la literatura y metaanálisis

    Antecedentes: Durante la gestaciĂłn el binomio materno-fetal se expone a procesos de cambio y eventos de riesgo, que de no ser manejados adecuadamente pueden terminar en enfermedad y muerte. La atenciĂłn materno-perinatal es un servicio que puede ser prestado tanto por profesionales de la salud como por personal tradicional. Algunos estudios plantean que las estrategias de intercambio de conocimiento pueden ser una herramienta Ăştil en el mejoramiento de procesos de atenciĂłn en salud. Objetivo: Identificar y resumir las estrategias de intercambio de conocimiento entre profesionales de la salud, parteras y trabajadores comunitarios para el mejoramiento de la salud materna. Fuentes de datos: bases de datos (Medline, CINAHL, Embase, PsycInfo, Lilacs, Wholis, Web of Science, ERIC, PASCASL IPA y/o Jstor via Ovid), organizaciones gubernamentales y no gubernamentales con bĂşsqueda de literatura desde 1946 hasta el 24/10/2019. Criterios de elegibilidad: se seleccionaron estudios cuantitativos y cualitativos que reportaran estrategias de intercambio de conocimiento entre profesionales de la salud, parteras y trabajadores comunitarios...Background: During gestation, the maternal-fetal pairing is exposed to processes of change and risk events, which, if not managed properly, can lead to illness and death. Maternal-perinatal care is a service that can be provided by both health professionals and traditional personnel. Some studies suggest that knowledge exchange strategies can be a useful tool in improving health care processes. Objective: To identify and summarize the knowledge exchange strategies between health professionals, midwives, and community workers for the improvement of maternal health.Data sources: databases (Medline, CINAHL, Embase, PsycInfo, Lilacs, Wholis, Web of Science, ERIC, PASCASL IPA and/or Jstor via Ovid), governmental and non-governmental organizations with literature search from 1946 to 24 / 10/2019. Eligibility criteria: quantitative and qualitative studies were selected that reported knowledge exchange strategies between health professionals, midwives, and community workers for the improvement of maternal health.

    Risk factors for SARS-CoV-2 transmission in close contacts of adults at high risk of infection due to occupation: results from the contact tracing strategy of the CoVIDA epidemiological surveillance study in Bogotá, Colombia, in 2020–2021

    Objectives To estimate the risk factors for SARS-CoV-2 transmission in close contacts of adults at high risk of infection due to occupation, participants of the CoVIDA study, in Bogotá D.C., Colombia.Setting The CoVIDA study was the largest COVID-19 intensified sentinel epidemiological surveillance study in Colombia thus far, performing over 60 000 RT-PCR tests for SARS-CoV-2 infection. The study implemented a contact tracing strategy (via telephone call) to support traditional surveillance actions performed by the local health authority.Participants Close contacts of participants from the CoVIDA study.Primary and secondary outcome measures SARS-CoV-2 testing results were obtained (RT-PCR with CoVIDA or self-reported results). The secondary attack rate (SAR) was calculated using contacts and primary cases features.Results The CoVIDA study performed 1257 contact tracing procedures on primary cases. A total of 5551 close contacts were identified and 1050 secondary cases (21.1%) were found. The highest SAR was found in close contacts: (1) who were spouses (SAR=32.7%; 95% CI 29.1% to 36.4%), (2) of informally employed or unemployed primary cases (SAR=29.1%; 95% CI 25.5% to 32.8%), (3) of symptomatic primary cases (SAR of 25.9%; 95% CI 24.0% to 27.9%) and (4) living in households with more than three people (SAR=22.2%; 95% CI 20.7% to 23.8%). The spouses (OR 3.85; 95% CI 2.60 to 5.70), relatives (OR 1.89; 95% CI 1.33 to 2.70) and close contacts of a symptomatic primary case (OR 1.48; 95% CI 1.24 to 1.77) had an increased risk of being secondary cases compared with non-relatives and close contacts of an asymptomatic index case, respectively.Conclusions Contact tracing strategies must focus on households with socioeconomic vulnerabilities to guarantee isolation and testing to stop the spread of the disease

    Objective: To identify and assess the effect of community-based Knowledge Translation Strategies (KTS) on maternal, neonatal, and perinatal outcomes.Methods: We conducted systematic searches in Medline, Embase, CENTRAL, CINAHL, PsycInfo, LILACS, Wholis, Web of Science, ERIC, Jstor, and Epistemonikos. We assessed the certainty of the evidence of the studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework.Results: We identified seven quantitative and seven qualitative studies. Quantitative findings suggest that there is a possible effect on reducing maternal mortality (RR 0.65; 95% CI, 0.48–0.87; moderate evidence certainty); neonatal mortality (RR 0.79; 95% CI 0.70–0.90; moderate evidence certainty); and perinatal mortality (RR 0.84; 95% CI 0.77–0.91; moderate evidence certainty) in women exposed to KTS compared to those who received conventional interventions or no intervention at all. Analysis of qualitative studies identified elements that allowed to generate benefit effects in improving maternal, neonatal, and perinatal outcomes.Conclusion: The KTS in maternal, neonatal, and perinatal outcomes might encourage the autonomy of communities despite that the certainty of evidence was moderate.</p
