Colonies wider than high, up to 120 mm in height and 200 mm in width. Most of the colonies are composed of a single fan, but some have two or three secondary fans that radiate from different parts of the main fan and grow parallel. Colour when preserved or alive is dark orange or reddish brown with lighter hues at the tips, and light ochre when dry. Colonies have a large holdfasts, and fans grow directly from this or sprout from short stems (up to 7 mm in diameter). Network is irregular. Meshes are very open (about 2–3 meshes/cm ²), mostly elongate, up to 45 mm in length, and 25 mm in width. Mesh branches are squarish in section, from 3 mm thick at their base to 1 mm at their tips. No midribs cross the fans, just some thick branches (up to 6 mm in diameter) at the base that diminish and merge with the fan. Endbranchlets are long; up to 25 mm in length. Freetwigs are abundant, up to 15 mm in length; they stick out from the fans, twist and grow parallel as free branches. The polyps are retracted within domeshaped coenenchymal mounds, which are prominent and arranged mostly in pairs along the sides of the branches. In dry specimens, the lateral distribution of the calices is more evident, and bands of coenenchyme are clear between them. The polyps are yellowish with rods arranged in strong, thick points, with some untidily arranged intermediate rods. The anthocodial rods are long, colourless or pale yellow (up to 0.18 mm in length and 0.02 mm in width). The coenenchymal sclerites are very ornamented, and are mostly large spindles (up to 0.22 mm in length, and 0.06 mm in width) with up to 8 complete whorls of tubercles, and warty ends. They are redorange to pale yellow and bicoloured, and together with P. s e n t a, include the longest spindles found in the genus. Capstans are less abundant in the slide samples; they are scarcely ornate, with only short tubercles. Holotype. The holotype (Fig. 1 G) is a single fan, 100 mm in height and 135 mm in width. Part of the holdfast was left behind when the specimen was collected. The preserved colony is reddish brown colony. Mesh branches are thick, about 2 mm in diameter. Numerous free twigs radiate from the fan as free branchlets. Endbranchlets reach 12 mm. Coenenchymal sclerites are redorange, pale yellow and bicoloured. They are mostly large spindles (up to 0.18 mm in length, and 0.06 mm in width) with 4–8 complete whorls of delicately sculpted tubercles, and with elongated warty ends, blunt, or acute (Fig. 5 A). There are also small, pale yellow capstans (up to 0.05 mm in length and 0.03 mm in width), and larger ones (up to 0.08 mm in length by 0.04 mm in width) with short, moderately warty tubercles (Fig. 5 B). Anthocodial sclerites are pale yellow. They are thin, long rods (up to 0.17 mm in length and 0.02 mm in width) with dentate margins and have acute, small warts, concentrated at the ends (Fig. 5 C). Remarks. This species is very similar to P. s e n t a, however, P. senta attains a larger size, the mesh branches are thinner, the meshwork finer (up to 23 mm long), and the colony has a more delicate appearance in comparison to the more robust P. sculpta. Dry specimens of P. s e n t a are brittle and the sclerites fall off easily, which is not the case in dry specimens of P. sculpta. Sclerites in both species are the largest recorded for the genus. Spindles in P. s e n t a and in P. sculpta reach the same size (up to 0.22 mm in length, and 0.06 mm in width), however, in P. s e n t a, the spindles have more whorls of tubercles (up to 10) than in P. sculpta (up to 8); thus sclerites of the latter have larger spaces between the whorls (and very warty tubercles). Capstans of both species are of similar shapes, but smaller sizes are reported for P. s e n t a (up to 0.06 mm in length) (Breedy & Guzman 2003 b). The colour of coenenchymal sclerites is definitely different. In all of the specimens of P. sculpta examined, two layers of differently coloured sclerites are clearly defined: reddishorange sclerites in the inner coenenchyme and pale yellow on the surface. In P. s e n t a, on the other hand, all sclerites are of the same colour; brownish pink to colourless. Anthocodial rods are also different, being shorter (up to 0.14 mm in length) and less spiny in P. s e n t a. We have found P. s c u l p t a at several localities in the Gulf of Chiriquí, and also from two sites in the Gulf of Panama, down to 30 m in depth. Breedy & Guzman (2003 b) pointed out that Stiasny (1943) dealt with a species from Isla del Rey, Gulf of Panama, sent to him by Hickson, which agrees with P. senta. Therefore, it was expected that P. s e n t a would be found to occur in Panama. Pacifigorgia senta has been collected from deeper waters, down to 40 m in Costa Rica. In recent collections made by dredging 35–60 m in depth, in Panamá, specimens of P. senta were indeed found, thus the occurrence of P. s e n t a is herein reported and confirmed. Curiously, both P. senta and P. sculpta, were collected together in the same dredge, what indicates that they may occur together. Habitat. Found from 10–40 m in depth, on vertical basaltic walls, living together with large P. e x i m i a colonies and many other octocorals. Though abundant in some places, this species is never the dominant species. Etymology. An adjective (L), sculptus = carved, in allusion to the ornamentation of the spindles. Distribution. Found widely distributed along Gulf of Panama, Gulf of Chiriquí, and Península de Azuero.Published as part of Breedy, Odalisca & Guzman, Hector M., 2004, New species of the gorgoniian genus Pacifigorgia (Coelenterata: Octocorallia: Gorgoniidae) from Pacific Panama, pp. 1-15 in Zootaxa 541 on pages 12-14, DOI: 10.5281/zenodo.15770

Willingness to receive the COVID-19 vaccine in the population aged 80 years and older in Colombia 2021
Colombia diseñó y adoptó un plan de vacunación contra la COVID-19. El objetivo de esta investigación fue conocer la disposición para aceptar la vacunación contra esa enfermedad de personas de 80 y más anos. ˜ Métodos: Se realizó una encuesta telefónica a 11.721 personas de 80 y más anos, ˜ afiliadas a una aseguradora de salud, en la que se indagó sobre la intención a recibir la vacuna. Los respondientes fueron los afiliados o sus familiares o cuidadores. Resultados: El promedio de edad fue 85,0 anos ˜ (DE: 4,5), sin diferencias entre sexos; 3.344 participantes (28,5%) refirieron el antecedente de haberse realizado una prueba diagnóstica previa de COVID-19 y 73 resultaron positivos. La incidencia acumulada de infección por SARS-CoV-2 desde marzo de 2020 fue de 622,8 por 100.000 personas (IC95%: 491-778 por 100.000). Respecto a la actitud hacia la vacunación contra la COVID-19, uno de cada 4 respondientes se abstuvo de opinar o se manifestó neutro. Cuando el respondiente era un familiar, la aceptación de la vacuna era del 60,4% (IC95%: 59,5-61,3) con diferencias por sexo: entre los hombres era del 62,2% (IC95%: 60,8-63,6) y en mujeres del 59,2 (IC95%: 58,0-60,3), con p < 0,05. Cuando el respondiente fue el potencial receptor de la vacuna, la aceptación de la vacuna fue del 61,7% (IC95%: 59,4-64,0) y también difería por sexos: 70,2% en hombres (IC95%: 66,9-73,5) y 55,1% en mujeres (IC95%: 52,0-58,3), con p < 0,05.Alvis Guzman, N.Alvis Zakzuk, J.Paz Wilches, J.Fernandez Mercado, J.C.de la Hoz Restrepo, F

EPH48 evolution of polypharmacy and prescribed drug expenditure: the case of an insured poor population in the colombian caribbean during 2018-2021
EVOLUTION OF POLYPHARMACY AND PRESCRIBED DRUG EXPENDITURE: THE CASE OF AN INSURED POOR POPULATION IN THE COLOMBIAN CARIBBEAN DURING 2018-2021 Gamero K,1 Alvis J,2 Mercado Fernandez JC,3 Paz Wilches J,4 Alvis Guzman N5 1 Distribuciones Pharmaser, Cali, VAC, Colombia, 2 Distribuciones Pharmaser, Cartagena, BOL, Colombia, 3 MUTUALSER EPS - University of Cartagena - Clínica Crecer, Cali, VAC, Colombia, 4 Mutual SER EPS, Cartagena, Colombia, 5 ALZAK Foundation- Universidad De La Costa, Barranquilla, Colombia Objectives: The aim of this study is to estimate the impact of the variation in the prevalence of polypharmacy rate in the prescribed drug expenditure (PDE). during 2018-2021. Methods: Cross sectional descriptive study of polymedicated patients (PP) during 2018-2021 was developed. Data was extracted from the individual outpatient dispense records from a health insurance company in Colombia. Polypharmacy and hypermedication were defined when patients consumed 10 medications in at least a continuous period. The number of patients attended, the number of medications per patient, defined daily doses (DDD) per patient (TI) and cost per DDD are calculated. Finally, a simulation of PDE of 2021 is developed in which the prevalence of polypharmacy is neutralized between 2018 and 2021 and keep the other variables constant. Results: Polypharmacy rate was 26,82% in 2018 and 31,17% in 2021. The PDE in 2015 constant US653,240 to 1,372,664, 110% higher than the PDE of 2018 due to the cost per DDD increased from 0.048, despite TI decreased from 333 to 286 but, lower than 2021 PDE because 2018 polypharmacy is lower. Conclusions: Polypharmacy has had a significant impact on the increase in PDE of the insurance company because in 2021 the cost per DDD increased as a consequence of the prescription of more expensive health technologies. The design of interventions and strict protocols need to be developed to mitigate the risk of non rational prescriptions in polymedicated patients and controlling the evolution of PDE

Guzman, 27 April 2002; UCR 1429, 1430, Bajo Urracá, 3–20 m, H.M. Guzman, 27 April 2002.</p> <p> <b>Description</b>. Colonies wider than high, up to 150 in height, and 220 mm in width, composed of one or more fans. New fans arise from the others and grow parallel to them. Colour when wet preserved is reddish­orange and dark red when dry; when alive they range from red to dark red. Colonies of different coloured hues can be found on the same site, even on the same rock. Colonies have a strong holdfast, and the fans commonly arise directly from this, but some colonies have short stems up to 10 mm in length. Networks are regular and of closed meshes (Fig. 1 F), mostly angular, up to 7 mm in length and 3 mm in width (about 8–9 meshes/cm²). Mesh branches are squarish in section, up to 2.0 mm in diameter. There are no distinct midribs, but some thick basal branches (up to 10 mm in width) can be traced for short distances into the fans. End­branchlets are more rounded than squarish in section, up to 5 mm in length, and have pointed tips. Free­twigs are short (up to 3 mm in length). The polyps are retracted within dome­shaped, coenenchymal mounds which are slightly raised, and closely crowded on the branches. They are mostly arranged in two to four alternating rows along the branches; more on thick branches. There is a very thin rim of orange sclerites around the polyp apertures. Polyps are white with rods arranged in weak points, some very small biscuit­like rods are found at the base of the tentacles. Coenenchymal sclerites are different combinations and abundances of pink, and hues of red, from reddish­orange to pale yellow, and also multicoloured; many of them show a yellowish halo. The surface of the branches contains dark yellow capstans sparsely distributed on a solid layer of orange and reddish­orange, larger capstans and spindles. In some specimens, however, almost all sclerites have the same colour, generally reddish­orange, but a shine from yellow sclerites on the branches can always be seen. The coenenchymal sclerites are mostly wide capstans and spindles, robustly tuberculate, becoming barrel­like. Anthocodial sclerites are light yellow rods.</p> <p> <b>Holotype</b>. The holotype (Fig. 1 E) is a dry, deep red colony, mostly a single fan, and 120 mm in height, and 200 mm in width. The holdfast was broken at the time of collection. No complete midribs are present, but a thick branch (up to 10 mm in width) at the base subdivides in two thinner ones, which extend up to 70 mm into the fan. At the base of the colony the black axis is visible. Some short branches spread at right angles to form three very small secondary fans at different levels of the colony. The coenenchymal sclerites are mostly wide capstans and spindles, strongly ornamented, mainly reddish­orange, but some are mixtures of these colours. The spindles (up to 0.14 mm in length and 0.05 mm in width) have a complex ornamentation, mostly arranged as four whorls of warty tubercles.</p> <p>The ends are elongate, pointed or rounded, and abundant asymmetric forms occur with one blunt end and the other acute (Fig. 4 A): a few spindles are arched. The capstans are mostly large (up to 0.10 mm in length and 0.05 mm in width), with strong, warty tubercles. The most characteristic capstans are light red with a clearly marked waist and two tyre–like whorls of tubercles (Fig. 4 B), which are frequently found in sclerite samples. Less abundant smaller capstans, dark yellow (about 0.05 mm in length and 0.04 mm in width) with wide tubercles (Fig. 4 B) are also present. Four­radiates (up to 0.06 by 0.06 mm) with warty ends (Fig. 4 C), and various immature types of sclerites are present (Fig. 4 D). Anthocodial sclerites are yellow, sometimes pale. They are long rods (up to 0.11 mm in length and up to 0.03 mm in width) mostly with smooth or wavy margins, and some with short lobe­like projections (Fig. 4 E).</p> <p> <b>Habitat</b>.
