Risk Factors for Fractures of Dogs in Quezon City, Philippines

A retrospective case-control study was conducted in dogs with bone fractures presented at the Veterinary Teaching Hospital - Diliman Station, Companion Animal Clinic, College of Veterinary Medicine, University of the Philippines Los Baños from January 2016 to December 2021. One hundred sixty-one dogs were diagnosed with bone fractures. Limping was the most common chief complaint with falling from a height being the most common cause. Close, complete, and oblique fractures were the most prevalent fracture type. Around 29.81% of the cases were given medications only and 16.77% were treated with external coaptation.  Among the cases treated with external coaptation, only fourteen came back for follow-up with fully healed bone fractures. The mean age of dogs with bone fractures was 2.30 years old and was seen as a significant risk factor regardless of age group. Dogs fed with dry dog food and table food were 0.35 and 0.50 less likely to have bone fractures, respectively. The body weight, body condition scores, and dog breeds were not significant risk factors while the abode of the animal was a significant risk factor regardless whether the animal is indoor or outdoor. Age, diet, and abode were found to be significantly associated with bone fractures

Story Retelling (SR) Technique in Improving Reading Comprehension of Sixth-Graders

The PHIL-IRI results of the sixth graders during their fifth grade were seriously alarming. All learners were identified as frustration readers. Thus, this study aimed to improve sixth graders' reading comprehension through Story Retelling (SR) technique. The study used a pretest-post-test quasi-experimental design consisting of two intact classes with 43 grade 6 learners. One class was exposed to SR Technique, while the other was exposed to the traditional method. The comparison of posttest results revealed no significant difference in the comprehension level of the respondents with (p>.01) between groups. The data proved that SR did not significantly enhance the reading comprehension of the learners. There was a slight increase in the posttest mean scores of the experimental group. However, the increase was not significant. It showed that the learners lacked solid general knowledge and vast vocabulary, which are essential in reading. The interviews discovered that the learners were not exposed to the English language and were not adequately monitored about their academic progress. These pre-existing background conditions significantly affected the intervention, preventing a significant difference in the learners' reading comprehension. Based on the results, it is recommended that the Story Retelling (SR) technique is only introduced to the learners after they learn the basic reading skills, including vocabulary, and establish solid general knowledge. Moreover, the amount of time spent on the intervention added to the undesirable results. Thus, the intervention should be conducted in more than six weeks to achieve better results

A comparison of the physical and chemical differences between cancellous and cortical bovine bone mineral at two ages

To assess possible differences between the mineral phases of cortical and cancellous bone, the structure and composition of isolated bovine mineral crystals from young (1–3 months) and old (4–5 years) postnatal bovine animals were analyzed by a variety of complementary techniques: chemical analyses, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and 31P solid-state magic angle spinning nuclear magnetic resonance spectroscopy (NMR). This combination of methods represents the most complete physicochemical characterization of cancellous and cortical bone mineral completed thus far. Spectra obtained from XRD, FTIR, and 31P NMR all confirmed that the mineral was calcium phosphate in the form of carbonated apatite; however, a crystal maturation process was evident between the young and old and between cancellous and cortical mineral crystals. Two-way analyses of variance showed larger increases of crystal size and Ca/P ratio for the cortical vs. cancellous bone of 1–3 month than the 4–5 year animals. The Ca/(P + CO3) remained nearly constant within a given bone type and in both bone types at 4–5 years. The carbonate and phosphate FTIR band ratios revealed a decrease of labile ions with age and in cortical, relative to cancellous, bone. Overall, the same aging or maturation trends were observed for young vs. old and cancellous vs. cortical. Based on the larger proportion of newly formed bone in cancellous bone relative to cortical bone, the major differences between the cancellous and cortical mineral crystals must be ascribed to differences in average age of the crystals

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Ethylcyclohexane Hydroconversion in EU-1 Zeolite: DFT-based Microkinetic Modeling Reveals the Nature of the Kinetically Relevant Intermediates

International audienceThe transformation of cycloalkanes is a key-reaction in refining and petrochemistry. Herein, we unravel the mechanism and the kinetics of the transformation of ethylcyclohexane, considering a bifunctional catalyst composed of platinum and of the EU-1 zeolite, by experiments, density functional theory (DFT) calculations and DFT-based microkinetic modeling. The simulated mechanisms involve carbenium intermediates. DFT shows the central kinetic role of the π-complexes corresponding to secondary carbenium ions. Cycle contractions and expansions appear to be rate-limiting. The DFT-based microkinetic model includes a limited number of kinetic parameters optimized by regression with respect to the experimental data. The agreement with experimental results is very good, showing that the mechanisms proposed, the nature of the intermediates, and the values of the computed rate constants, are relevant. The reaction starts by the cycle contraction of 1-ethylcyclohexene, then shifts to a second sequence of cycle expansion-contraction reactions by intercalated methyl-shifts
