Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Ethical climate in a state institution

16 páginasThe present investigation identifies ethics in the organizational environment of a government institution, related to factors such as: egocentrism, kindness or benevolence and principles. The organizational environment refers to the shared perception of an ethical action and how ethical situations are carried out in an institution (Cullen & Victor, 1988). Participants included 63 workers in the institution. The results showed evidence that confirms the presence of benevolence, related to: team- group ideas and principles that are related to norms and laws carried out in the role. These results confirm the practices carried out by the institution, its workers, and its relevance with the formation evaluated by the performance in a role.Esta investigación identificó el clima ético en una Institución del estado relacionado con los factores de egoísmo, benevolencia y principios. El clima corresponde a las percepciones compartidas sobre lo que es una acción éticamente correcta y cómo los temas éticos son desarrollados en una Institución (Cullen y Victor, 1988). Participaron en el estudio 63 funcionarios. Los resultados evidencian la presencia en la Institución del factor de benevolencia relacionado con las ideas de grupo y equipo, y el factor de principios por la tendencia a cumplir con normas y leyes establecidas en el cargo. Estos resultados confirman las prácticas de la Institución sobre los funcionarios y la coherencia con la formación impartida que se evalúa en el desempeño en el cargo

Estimación de parámetros genéticos de características de crecimiento predestete del bovino criollo de raza sanmartinero (SM)

Titulo en ingles:  Genetic parameter estimates of preweaning growth traits of the Sanmartinero creole  cattle.RESUMEN: En Colombia existen ocho razas de bovinos criollos (Bos taurus), descendientes de los ganados introducidos por los conquistadores   españoles en 1493, en el segundo viaje de Cristóbal Colon; entre ellas se encuentra el ganado Sanmartinero (SM) el cual se formó en el piedemonte llanero de la Orinoquia colombiana y, al igual que la mayoría de las razas criollas colombianas, se encuentra en peligro de extinción, ya que su población actual no es mayor a los 3000 animales. Esta raza es de gran importancia por su gran potencial adaptativo y por sus excelentes características de producción para el trópico colombiano.Este estudio analizó la base de datos del Centro de Investigaciones (C.

Igualmente, se calcularon los índices de heredabilidad (h2) y las correlaciones genéticas, ambientales y fenotípicas para éstas características.Los promedios generales ± desviación estándar fueron los siguientes: PN, 27.02 Kg. ± 3.10; GDND, 0.580 Kg. ± 0.097; y PAD, 166.62 Kg. ± 23.57; Las h2 ± error estándar de estas características fueron PN, 0.26 ± 0.08; PAD, 0.14 ± 0.07 y GDND, 0.52 ± 0.12; las correlaciones genéticas (rg) fueron 0.74 para (PN, GDND), 0.70 (PN, PAD) y 0.98 (PAD, GDND). Se concluye que la raza SM, pese a su disminuida población, posee amplia variabilidad genética y adecuado potencial genético para la producción pecuaria sostenible del trópico colombiano, razones suficientes para evitar su extinción.Palabras clave: Razas criollas, Sanmartinero, parámetros genéticos, características de crecimiento.ABSTRACT:  Colombia has eight Creole breeds (Bos taurus), these being descended from the cattle introduced by the Spanish conquerors in 1493, during Christopher Columbus' second voyage. The Sanmartinero (SM) breed originated in the Colombian Orinoquia region's foothills. This breed (as well as most other Creole breeds) is at risk of extinction due to its small population size, consisting of less than 3,000 animals. This breed is very important due to its adaptability to the Colombian tropics and related excellent production characteristics. This study analysed data recorded from 1971 to 1996 at La Libertad Research Station, Villavicencio, Meta. Statistical analysis system (SAS) software was used for analysing growth traits such as birth-weight (BW), weaning-weight adjusted to 240 days (WW) and daily pre-weaning gain (WG), using a general lineal model (GLM). Furthermore, heritability (h2) for all characteristics was measured and genetic, environmental and phenotypic correlations were also calculated.Means and standard deviations were as follows: 27.02 Kg. ± 3.10 BW, 0.580 Kg. ± 0.097 WG and 166.62 Kg. ± 23.57 WW. h2 ± standard errors for these characteristics were 0.26 ± 0.08 BW, 0.14 ± 0.07 WW and 0.52 ± 0.12 WG. Genetic correlations (rg) amongst pre-weaning traits were: 0.74 for BW cf WG; 0.70 for BW cf WW and 0.98 for WW cf WG. It was thus concluded that the SM breed (in spite of its reduced population size) still has large genetic variation and good genetic potential for sustainable livestock production in the Colombian tropics, these being reasons enough for trying to prevent its extinction.Key words: Creole breed, Sanmartinero cattle, genetic parameter s, growth traits.Titulo en ingles:  Genetic parameter estimates of preweaning growth traits of the Sanmartinero creole  cattle.RESUMEN: En Colombia existen ocho razas de bovinos criollos (Bos taurus), descendientes de los ganados introducidos por los conquistadores   españoles en 1493, en el segundo viaje de Cristóbal Colon; entre ellas se encuentra el ganado Sanmartinero (SM) el cual se formó en el piedemonte llanero de la Orinoquia colombiana y, al igual que la mayoría de las razas criollas colombianas, se encuentra en peligro de extinción, ya que su población actual no es mayor a los 3000 animales.

Effect of Moxidectin Treatment at Peripartum on Gastrointestinal Parasite Infections in Ewes Raised under Tropical Andes High Altitude Conditions

This study tested the impact of moxidectin at peripartum on nematode fecal egg count (FEC) and clinical parameters on ewes in the high altitude tropical Andes of Colombia. FEC and clinical evaluations were performed on 9 occasions in 43 naturally infected ewes before and during gestation and after lambing. Moxidectin (Mox, 200 µg kg−1) was applied at late pregnancy (T1, n=15) or 48 hours after parturition (T2, n=14). 14 untreated ewes served as controls (C). Suckling lambs (n=58) remained untreated and underwent four clinical and parasitological evaluations until 8 weeks after birth. Mox efficacy equaled 99.3% (T1) and 96.9% (T2). Highest mean FEC value reflecting periparturient nematode egg rise (PPER) was recorded in C ewes at 4–6 weeks after lambing. Significant FEC reductions were found in T1 (94.8%) and T2 (96.7%) ewes (p<0.05). All lambs showed a significant and ewes-group independent increase in FEC before weaning (p<0.05). Clinical parameters (anemia and diarrhea) showed time- and treatment-related differences (p<0.05). Monitoring of FEC and clinical parameters linked to gastrointestinal parasite infections allowed demonstrating that postpartum or preweaning are two critical periods to nematode infection for sheep raised under tropical Andes high altitude conditions. Use of Mox as anthelmintic treatment prevented PPER

Second San Juan photoelectric astrolabe catalogue

According to the cooperation between Beijing, San Juan and La Plata Astronomical Observatories, the photoelectric astrolabe Mark II(PAII) of the Beijing Astronomical Observatory was moved and installed at the San Juan Observatory, Argentina in January, 1992 for observations of the catalogue of stars in the southern hemisphere. The first observing period was from Feb. 23, 1992 to Mar. 31, 1997. Using the data observed in San Juan with the instrument during this period, residuals for 11002 stars are reduced from about 405700 observations of stars over 1532 days. The mean precision of the residuals is ± $0.043''$. The Second Catalogue of Stars (CPASJ2) has been compiled from double transits at both the eastern and western passages. There are 5241 stars in this catalogue, including 1225 FK5/FK4Supp stars, 794 FK5Ext stars, 1084 SRS stars, 937 CAMC4 stars, 310 GC stars and 891 IMF stars. The mean precisions are ±3.2ms and ± $0.057''$ in right ascension and declination, respectively. The magnitudes of stars are from 2.0 to 11.5. The declinations are from $-3^\circ$ to $-60^\circ$. The mean epoch is 1994.9. Finally, systematic corrections of(CPASJ2-FK5) are given
