Drivers for universities’ contribution to the sustainable development goals: An analysis of Spanish public universities
Universities have a critical role in achieving the Sustainable Development Goals (SDGs), both for implementing active policies and for encouraging other actors to participate. This requires having the skills and mind-sets to contribute to these challenges. The relevance and the commitment of universities to sustainability has led to the inclusion of SDGs in the strategies and agendas of these institutions. This requires the involvement of all the actors and some structural and cultural changes that put SDGs at the core of the governance and management of the university, embracing all the stakeholders. Various internal and external factors may influence the impact and success of the policies and activities aiming at achieving the SDGs, both from an overall perspective and for individual SDGs. This paper assesses the influence of some internal factors, such as the presence of universities on the internet, the level of internationalization or the availability of financial resources. Through both regression analyses and the Gephi method, our results confirm the importance of the presence on the internet, the internationalization of the university and the financial resources for research and infrastructure received from regional governments for Spanish public universities to make a greater contribution to SDGs
Knowledge, Attitudes, and Practices Associated with Brucellosis in Livestock Owners in Jordan
We evaluated livestock owners' knowledge, attitudes, and practices regarding brucellosis in Jordan. A questionnaire was administered and biological samples were examined to verify the serological status of animals. Seroprevalence estimates indicated that 18.1% (95% CI: 11–25.3) of cattle herds and 34.3% (95% CI: 28.4–40.4) of small ruminant flocks were seropositive. The results showed that 100% of the interviewed livestock keepers were aware of brucellosis: 87% indicated a high risk of infection if unpasteurized milk is consumed and 75% indicated a high risk if unpasteurized dairy products are consumed. Awareness of the risk of infection through direct contact with fetal membranes or via physical contact with infected livestock is considerably lower, 19% and 13%, respectively. These knowledge gaps manifest in a high frequency of high-risk practices such as assisting in animal parturition (62%), disposing aborted fetuses without protective gloves (71.2%) or masks (65%), and not boiling milk before preparation of dairy products (60%). When brucellosis is suspected, basic hygiene practices are often disregarded and suspect animals are freely traded. Public health education should be enhanced as the disease is likely to remain endemic in the ruminant reservoir as long as a suitable compensation program is not established and trust on available vaccines is regained
Changes in Social and Clinical Determinants of COVID-19 Outcomes Achieved by the Vaccination Program: A Nationwide Cohort Study
Background: The objective of this study was to assess changes in social and clinical
determinants of COVID-19 outcomes associated with the first year of COVID-19 vaccination rollout in
the Basque population. Methods: A retrospective study was performed using the complete database
of the Basque Health Service (n = 2,343,858). We analyzed data on age, sex, socioeconomic status,
the Charlson comorbidity index (CCI), hospitalization and intensive care unit (ICU) admission, and
COVID-19 infection by Cox regression models and Kaplan–Meier curves. Results: Women had a
higher hazard ratio (HR) of infection (1.1) and a much lower rate of hospitalization (0.7). With older
age, the risk of infection fell, but the risks of hospitalization and ICU admission increased. The higher
the CCI, the higher the risks of infection and hospitalization. The risk of infection was higher in
high-income individuals in all periods (HR = 1.2–1.4) while their risk of hospitalization was lower in
the post-vaccination period (HR = 0.451). Conclusion: Despite the lifting of many control measures
during the second half of 2021, restoring human mobility patterns, the situation could not be defined
as syndemic, clinical determinants seeming to have more influence than social ones on COVID-19
outcomes, both before and after vaccination program implementation
The celiac axis compression syndrome (CACS): critical review in the laparoscopic era
The celiac axis compression syndrome (CACS) due to median
arcuate ligament (MAL) was first described by Harjola in 1963;
originating postpandrial abdominal pain, weight loss, epigastric
bruit and celiac axis stenosis > 75% in angiographic studies. This
clinical condition has been the origin of controversies about its
pathogenesis, diagnosis and its long term clinical results.
Advances in diagnostic imaging as 64 multidetector–row CT
(MDCT), 3-D reconstruction, magnetic resonance (MR) and color
duplex ultrasonography, provide better understanding of the syndrome
and allow to identify the best candidates for surgical division
of MAL fibers.
Since the introduction of laparoscopic approach, and also endovascular
procedures, in 2000, a new perspective has established
in this challenging syndrome. With the occasion of our own
experience, a critical review of the syndrome is presented
Histone deacetylase inhibitors promote glioma cell death by G2 checkpoint abrogation leading to mitotic catastrophe
Glioblastoma multiforme is resistant to conventional anti-tumoral treatments due to its infiltrative nature and capability of relapse; therefore, research efforts focus on characterizing gliomagenesis and identifying molecular targets useful on therapy. New therapeutic strategies are being tested in patients, such as Histone deacetylase inhibitors (HDACi) either alone or in combination with other therapies. Here two HDACi included in clinical trials have been tested, suberanilohydroxamic acid (SAHA) and valproic acid (VPA), to characterize their effects on glioma cell growth in vitro and to determine the molecular changes that promote cancer cell death. We found that both HDACi reduce glioma cell viability, proliferation and clonogenicity. They have multiple effects, such as inducing the production of reactive oxygen species (ROS) and activating the mitochondrial apoptotic pathway, nevertheless cell death is not prevented by the pan-caspase inhibitor Q-VD-OPh. Importantly, we found that HDACi alter cell cycle progression by decreasing the expression of G2 checkpoint kinases Wee1 and checkpoint kinase 1 (Chk1). In addition, HDACi reduce the expression of proteins involved in DNA repair (Rad51), mitotic spindle formation (TPX2) and chromosome segregation (Survivin) in glioma cells and in human glioblastoma multiforme primary cultures. Therefore, HDACi treatment causes glioma cell entry into mitosis before DNA damage could be repaired and to the formation of an aberrant mitotic spindle that results in glioma cell death through mitotic catastrophe-induced apoptosis
Pattern and Outcome of Chest Injuries at Bugando Medical Centre in Northwestern Tanzania.
Chest injuries constitute a continuing challenge to the trauma or general surgeon practicing in developing countries. This study was conducted to outline the etiological spectrum, injury patterns and short term outcome of these injuries in our setting. This was a prospective study involving chest injury patients admitted to Bugando Medical Centre over a six-month period from November 2009 to April 2010 inclusive. A total of 150 chest injury patients were studied. Males outnumbered females by a ratio of 3.8:1. Their ages ranged from 1 to 80 years (mean = 32.17 years). The majority of patients (72.7%) sustained blunt injuries. Road traffic crush was the most common cause of injuries affecting 50.7% of patients. Chest wall wounds, hemothorax and rib fractures were the most common type of injuries accounting for 30.0%, 21.3% and 20.7% respectively. Associated injuries were noted in 56.0% of patients and head/neck (33.3%) and musculoskeletal regions (26.7%) were commonly affected. The majority of patients (55.3%) were treated successfully with non-operative approach. Underwater seal drainage was performed in 39 patients (19.3%). One patient (0.7%) underwent thoracotomy due to hemopericardium. Thirty nine patients (26.0%) had complications of which wound sepsis (14.7%) and complications of long bone fractures (12.0%) were the most common complications. The mean LOS was 13.17 days and mortality rate was 3.3%. Using multivariate logistic regression analysis, associated injuries, the type of injury, trauma scores (ISS, RTS and PTS) were found to be significant predictors of the LOS (P < 0.001), whereas mortality was significantly associated with pre-morbid illness, associated injuries, trauma scores (ISS, RTS and PTS), the need for ICU admission and the presence of complications (P < 0.001). Chest injuries resulting from RTCs remain a major public health problem in this part of Tanzania. Urgent preventive measures targeting at reducing the occurrence of RTCs is necessary to reduce the incidence of chest injuries in this region
Determination of organochlorine pesticide residues in honey from the central zone of Portugal and the Valencian community of
Abstract In this study nine organochlorine pesticide residues (␣-, -, and ␥-hexachlorocyclohexane (HCH), hexachlorobenzene (HCB), aldrin, p,p -DDE, p,p -DDD, o,p -DDT, and p,p -DDT) in forty nine samples of honey collected from markets of Portugal and Spain during 2001 and 2002, respectively, were evaluated. For this evaluation, three analytical procedures were studied. The analytical procedure, based on LLE extraction with ethyl acetate followed by gas chromatography-electron-capture detection (GC-ECD) for quantification, and mass spectrometry (GC-MS) for confirmation, has been selected. Recoveries of spiked samples ranged from 68%, for -HCH, and 126% for p,p -DDT, for fortification levels between 10 and 100 g/kg, and 64%, for ␣-HCH, and 143% for ␥-HCH for fortification levels between 20 and 200 g/kg. Limits of quantification, using GC-ECD, were from 0.01 and 0.10 mg/kg, and limits of detection between 0.001 and 0.02 mg/kg. Fourteen Valencian samples were contaminated, containing residues of HCB or/and HCH isomers. The frequency of detection was 56% for Spanish samples. In Portugal, 23 samples were contaminated, what means 95.8%. In Spanish samples, concentrations range from nd to 0.03 mg/kg for HCB, and nd to 2.24 mg/kg for HCH-total. The mean concentration and standard deviation were 0.017 ± 0.011 mg/kg for HCB, and 0.579 ± 0.747 mg/kg for HCH-total, contributing the ␥ isomer with the highest values. The samples from Portugal showed higher levels. Levels of HCB ranged from nd to 0.39 mg/kg. HCH-total ranged from nd to 4.86 mg/kg, and DDT-total from nd to 0.658 mg/kg. Mean concentration and standard deviation were 0.09 ± 0.116 mg/kg for HCB, 1.357 ± 1.30 mg/kg for HCH-total, and 0.143 ± 0.193 mg/kg for DDT-total
Local structural changes in paramagnetic and charge ordered phases of Sm0.2Pr0.3Sr0.5MnO3: An EXAFS Study
Sm{0.5-x}Pr{x}Sr{0.5}MnO{3} exhibits variety of ground states as x is varied
from 0 to 0.5. At an intermediate doping of x = 0.3 a charge-ordered CE type
antiferromagnetic insulating (AFI) ground state is seen. The transition to this
ground state is from a paramagnetic insulating (PMI) phase through a
ferromagnetic metallic phase (FMM). Local structures in PMI and AFI phases of x
= 0.3 sample have been investigated using Pr K-edge and Sm K-edge Extended
X-ray Absorption Fine Structure (EXAFS). It can be seen that the tilting and
rotation of the MnO6 octahedra about the b-axis are responsible for the charge
ordered CE-type antiferromagnetic ground state at low temperatures. In addition
a shift in the position of the rare earth ion along the c-axis has to be
considered to account for observed distribution of bond distances around the
rare earth ion
