Marked variability in institutional deliveries and neonatal outcomes during the COVID-19 lockdown in Nigeria.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic and the interventions to mitigate its spread impacted access to healthcare, including hospital births and newborn care. This study evaluated the impact of COVID-19 lockdown measures on newborn service utilization in Nigeria. METHODS: The records of women who delivered in hospitals and babies admitted to neonatal wards were retrospectively reviewed before (March 2019-February 2020) and during (March 2020-February 2021) the COVID-19 pandemic lockdown in selected facilities in Nigeria. RESULTS: There was a nationwide reduction in institutional deliveries during the COVID-19 lockdown period in Nigeria, with 14 444 before and 11 723 during the lockdown-a decrease of 18.8%. The number of preterm admissions decreased during the lockdown period (30.6% during lockdown vs 32.6% pre-lockdown), but the percentage of outborn preterm admissions remained unchanged. Newborn admissions varied between zones with no consistent pattern. Although neonatal jaundice and prematurity remained the most common reasons for admission, severe perinatal asphyxia increased by nearly 50%. Neonatal mortality was significantly higher during the COVID-19 lockdown compared with pre-lockdown (110.6/1000 [11.1%] vs 91.4/1000 [9.1%], respectively; p=0.01). The odds of a newborn dying were about four times higher if delivered outside the facility during the lockdown (p<0.001). CONCLUSIONS: The COVID-19 lockdown had markedly deleterious effects on healthcare seeking for deliveries and neonatal care that varied between zones with no consistent pattern.

A simple and cost effective method for preparing FL and LG solutions.

PURPOSE: The purpose of this study was to develop a clinically feasible method for obtaining dye concentrations of 2% fluorescein (FL) and 1% lissamine green (LG) by soaking commercially available dye impregnated strips in saline. METHODS: Calibration curves were established to related known concentrations of dye to prepared FL fluorescence and LG absorbance. To determine the optimum number of dye strips and soaking times (preliminary testing), 1, 2, 3 FL or LG strips were soaked in 200 µl commercially available saline for 0.5, 1, 2, 3, 4 and 5 min, using calibration curves to determine FL and LG concentrations. The best combination of number of dye strips and soaking time was soaking 3FL and 3LG strips for 5 min and these were finally tested in 2 ml centrifuge tubes, selected for ease of use in a clinical setting. RESULTS: Preliminary testing indicated that soaking 3 FL or 3 LG strips for 5 min in saline yielded an average (±standard deviation) of 2.0 ± 0.000% FL and 0.93 ± 0.010% LG. Final testing of FL in centrifuge tubes (strips soaked for 3-15 min) yielded an average of 1.99 ± 0.040% FL, with no significant difference among time periods or dye lots tested. However, LG showed more variable results with an average of 0.80 ± 0.160% LG (5-15 min), with significant differences among dye lots and times (2-way ANOVA, p < 0.05). CONCLUSIONS: This simple, reliable and relatively inexpensive method involves soaking 3 FL or LG strips in saline solution, yielding concentrations close to the 2%FL and 1%LG recommended for clinical trials, although LG showed more variability.

The unholy trinity: The Dark Triad, coercion, and Brunswik-Symmetry.

Psychopathy, Narcissism, and Machiavellianism (the Dark Triad) have each been hypothesized as predictors of socially deviant behavior including sexual coercion, but the three traits also covary significantly with one another. The purpose of this study was to examine several alternative Multisample Structural Equation Models (MSEMs) exploring the relations between the Dark Triad and Sexually Coercive Behavior, testing whether any or all of the three specific "Dark Personality" traits uniquely contributed to predicting sexually coercive behavior. Self-report questionnaires measuring Primary and Secondary Psychopathy, Narcissism, Machiavellianism, and Sexually Coercive Behavior were administered to a sample of undergraduates. The relative fit of each of the MSEMs to the data was examined by means of hierarchically nested model comparisons. The most parsimonious yet explanatory model identified was one in which a single common factor composed of the three Dark Triad indicators explained the relationships among the Dark Triad traits and Sexually Coercive Behavior without any direct contributions from the specific Dark Triad indicators. Results indicate that the three Dark Triad traits, controlling for the common factor, do not differentially predict Sexually Coercive Behavior. These results are interpreted with respect to the principle of Brunswik-Symmetry.

Nuevas técnicas en esquemas conceptuales para construir conocimientos en tecnologías de la Salud / New techniques in conceptual eschemic to build knowleges in health tecnology

Se realiza una investigación cualitativa, como parte de la tercera tarea del macroproyecto GEMDITPS para la Ortopedia Pediátrica, referente a el desarrollo de estrategias para la educación y promoción de conocimientos tecnológicos de salud ante las deformidades ortopédicas más frecuentes de nuestro medio; en ellas se han logrado establecer y validar teóricamente más de cuatro técnicas o estrategias pedagógicas en las cuales se destaca la propuesta de esta publicación de la cual solo hacemos una síntesis de su contenido y forma (AU)
