Association between eating habits and quality of life among Chilean university students.

Objective To estimate the association between eating habits and quality of life (QOL) in Chilean university students. Participants: 1,212 students from the Universidad de La Frontera, Chile (mean age 18.7 ± 2.15) were surveyed in January-March 2018. Methods: Participants completed a cross-sectional self-report survey to evaluate QOL using the WHOQOL-BREF scale and eating habits with a food habits survey. Results: Students reporting a better healthy eating habits score also presented a higher QOL. Eating breakfast and eating home-cooked meals is a protective factor for QOL in each domain. The consumption of sweet snacks was shown to be a risk factor for the physical health and environment domains. The consumption of fast food is shown as the greatest risk factor in the physical domain. Conclusion: Healthy and unhealthy eating habits are associated with different dimensions of QOL. University authorities should develop new policies to improve the QOL of the entire university community.

Sclerosing angiomatoid nodular transformation of the spleen: unusual case presentation in an intravenous drug user.

An unusual presentation of sclerosing angiomatoid nodular transformation in a 42-year-old man who was admitted with jaundice, deranged liver function tests and subsequently diagnosed with acute hepatitis C infection in the context of recent intravenous drug use. During his admission, he had an ultrasound of the abdomen followed by a CT thorax, abdomen and pelvis which showed splenomegaly and a large splenic lower pole mass that was hypoechoic and concerning for lymphoma. A bone marrow biopsy showed no evidence of lymphoma and an ultrasound-guided biopsy of the splenic mass suggested unusual features with vascular proliferation, either neoplastic or reactive, with no evidence of lymphoma or high-grade sarcoma. Given the concern for malignancy, an open splenectomy was required to determine the nature of the lesion with histologic findings consistent with a non-neoplastic benign vascular lesion favouring sclerosing angiomatoid nodular transformation.

[Association between cardiometabolic risk factors, physical activity and sedentariness in Chilean university students]. / Asociación entre factores de riesgo cardiometabólicos, actividad física y sedentarismo en universitarios chilenos.

INTRODUCTION: There is a huge evidence in adults, that a high level of physical activity and a low level of sedentariness are associated independently with a reduction of cardiometabolic risk factors (CMRF). This association has been poor evaluated in young people and the results are not conclusive. OBJECTIVE: To estimate the association between CMRF, physical activity and sedentariness in Chilean university students. METHODS: Cross-sectional study. Sample of 326 students who enrolled at University of La Frontera, Temuco, Chile, in 2014. They were selected randomly and stratified according to faculty, career and gender. We measured anthropometry, blood pressure, lipidic profile, glycemia, insulin resistance, tobacco and alcohol consumption. These variables were associated with physical activity level (PAL) and sedentariness using the IPAQ questionnaire. RESULTS: The students with a low PAL had a higher probability of abdominal obesity (OR: 4.68; IC 95% 1.86-11.73), metabolic syndrome (OR: 3.80; IC 95% 1.23-11.73) and triglycerides elevated (OR: 2.61 IC 95%; 1.18-5.75), compared with students with moderate and vigorous PAL (p < 0.05). There were no association between CMRF and sedentariness, even after fit by physical activity. CONCLUSIONS: We found an association between CMRF and PAL which was independent of sedentatiness. We believe it is very important to implement effective physical activity programs at universities. It is necesary to encourage students in order to increase the physical activity level to a moderate and vigorous range with the purpose of decreasing their cardiovascular risk. We consider it is recommendable to keep studying the association between sedentariness and CMRF.

Asociación entre factores de riesgo cardiometabólicos, actividad física y sedentarismo en universitarios chilenos / Association between cardiometabolic risk factors, physical activity and sedentariness in Chilean university students

Introducción: existe una amplia evidencia en población adulta de que un alto nivel de actividad física y un bajo nivel de sedentarismo se asocian de forma independiente con una reducción de los factores de riesgo cardiometabólico (FRCM). Esta asociación ha sido poco estudiada en población joven y los resultados no son concluyentes. Objetivo: estimar la asociación entre FRCM, actividad física y sedentarismo en estudiantes universitarios chilenos. Métodos: estudio de corte transversal. Muestra de 326 estudiantes matriculados el año 2014 en la Universidad de La Frontera, Temuco, Chile, seleccionados en forma aleatoria, estratificada según facultad, carrera y sexo. Se evaluó antropometría, presión arterial, perfil lipídico, glicemia, insulinorresistencia, consumo de tabaco y alcohol. Estas variables se asociaron con los niveles de actividad física (NAF) y sedentarismo, de acuerdo al cuestionario IPAQ. Resultados: los estudiantes con un NAF bajo tuvieron mayor probabilidad de tener obesidad abdominal (Odds ratio [OR]: 4,68; IC 95% 1,86-11,73), síndrome metabólico (OR: 3,80; IC 95% 1,23-11,73) y triglicéridos elevados (OR: 2,61 IC95%; 1,18-5,75), en comparación con aquellos estudiantes que realizaban NAF moderados o vigorosos (p < 0,05). No se observó asociación entre FRCM y sedentarismo, incluso después de ajustar por actividad física. Conclusión: encontramos asociación entre FRCM y NAF, que fue independiente del sedentarismo. Es de suma importancia implementar programas de actividad física efectivos en las universidades, motivando a los estudiantes a incrementar los NAF a rangos moderado y vigoroso, con el fin de reducir el riesgo cardiovascular. Consideramos que es necesario seguir investigando la asociación entre sedentarismo y FRCM (AU)

[Cardiovascular risk factors among first and third year university students]. / Factores de riesgo cardiovascular en universitarios de primer y tercer año.

BACKGROUND: College students are in a critical stage in their life style due to the transition between high school and university and they may be prone to develop cardiovascular diseases. AIM: To compare the prevalence of cardiovascular risk factors (CVRF) in students from first and third year at the University of La Frontera, Temuco-Chile, according to faculty, gender and socioeconomic status (SES). MATERIAL AND METHODS: Cross-sectional study. Anthropometry, blood pressure, lipid profile, blood glucose, insulin resistance (IR), sedentary lifestyle, tobacco and alcohol consumption were evaluated during 2014 in randomly selected 163 freshmen aged 19.2 ± 1.8 years and 163 third year students aged 21.7 ± 2.5 years (49% females), stratified by faculty, career and gender. RESULTS: 32.4% of students had prehypertension, 30.6% abdominal obesity, 26.3% insulin resistance, 25.7% dyslipidemia and 8.9% metabolic syndrome. Third grade students had higher prevalence of elevated total and LDL cholesterol and higher alcohol consumption, especially among students of middle and high socioeconomic level. Compared with students from the School of Medicine, students from the Education Faculty had 3.9, 3.3 and 2.7 times greater likelihood of being obese, having elevated LDLcholesterol and being smokers, respectively. Women had the highest prevalence of sedentary lifestyles and dyslipidemia. Men had the highest prevalence of prehypertension and smoking. CONCLUSIONS: Educational programs are required to promote healthy lifestyles among these students.

Does pain predict outcome in hips with osteonecrosis?

It generally is accepted that without specific treatment 70-80% of hips with clinically diagnosed osteonecrosis will progress to collapse. However, there are conflicting reports regarding the relationship between pain and outcome before femoral head collapse. Some surgeons are reluctant to operate on patients with asymptomatic or minimally symptomatic hips, assuming that these patients have a better prognosis than patients with pain. This study reviewed the outcome of 328 hips in 235 patients with nontraumatic osteonecrosis, all treated with core decompression and grafting. The preoperative stage, the extent of necrosis, and the Harris pain scores were correlated with the clinical and radiographic outcomes. Mean followup was 46 months. Patients with hips treated surgically did better as a group than patients with hips treated without surgery. A direct correlation was found between outcome and the stage and size of the necrotic lesion. Hips that had femoral head collapse were more painful than hips that did not have collapse and had a poorer outcome. Before collapse, outcome was correlated with the size of the necrotic lesion but there was no correlation with the preoperative pain level. These findings, although limited to patients with hips which had core decompression and grafting, support the observations of investigators who reported that most asymptomatic hips with osteonecrosis would progress without specific treatment. They also may apply to hips which have other forms of prophylactic treatment. Although several factors must be considered in determining the optimum treatment of hips with early stages of osteonecrosis, prophylactic treatment should not be withheld specifically because of the absence or paucity of pain.
