ABSTRACT
Objective@#To investigate HPV vaccine hesitation and associated factors among female college students in Weifang, and to provide a suggestions for improving the coverage rate of HPV vaccine among female college students.@*Methods@#The questionnaire of HPV vaccine hesitancy of female college students was designed. By adopting the stratified sampling method, the survey was conducted among female students at one medical university and three nonmedical universities in Weifang. Chi-square test and Logistic regression were used to analyze the influencing factors of vaccine hesitation.@*Results@#Female college students who had high risk perception toward vaccine (OR=4.15, 95%CI=1.55-11.10) and those who were angry about the sideeffects of the vaccine (OR=3.63, 95%CI=1.95-6.75) were hesitate to vaccinate against HPV. Female college students who believed long protection period of HPV vaccine (OR=0.08, 95%CI=0.04-0.17), that women had a high probability of cervical cancer (OR=0.44, 95%CI=0.21-0.90) and that the knowledge of HPV vaccine scored >6 (OR=0.31, 95%CI=0.15-0.67) were more likely to receive HPV vaccine.@*Conclusion@#High risk perception of vaccines and anger at vaccine adverse reactions are important factors affecting HPV vaccines for female college students. Our findings call for strategic role of the state, school-based health education as well as medical professional guidance in lowering HPV vaccination hesitation among fenale college sutdents.
ABSTRACT
Abstract Background: Right ventricular function is a crucial factor of the prognosis of systemic lupus erythematosus (SLE). Objectives: To evaluate the right ventricular function in SLE patients with different degrees of pulmonary hypertension (PH) by strain and strain rate imaging. Methods: A total of 102 SLE patients and 30 healthy volunteers were studied between October 2015 and May 2016. Patients were divided into three groups according to pulmonary artery systolic pressure (PASP) estimated by echocardiography: group control (A); PASP ≤ 30 mmHg (group B, n = 37); PASP 30-50 mmHg (mild PH; group C, n = 34); and PASP ≥ 50 mmHg (moderate-to-severe PH; group D, n = 31). Longitudinal peak systolic strain (ε) and strain rate (SR), including systolic strain rate (SRs), early diastolic strain rate (SRe) and late diastolic strain rate (SRa) were measured in the basal, middle and apical segments of the right ventricular free wall in participants by two-dimensional speckle tracking echocardiography (2D-STE) from the apical four-chamber view. A p < 0.05 was set for statistical significance. Results: The parameters of ε, SRs, SRe, and SRa were significantly decreased in groups C and D compared with groups A and B. The ε of each segments was significantly lower in group D than in group C, while there were no differences in SRs, SRe and SRa between groups C and D. Conclusions: Strain and strain rate imaging could early detect the right ventricular dysfunction in SLE patients with PH, and provide important value for clinical therapy and prognosis of these patients.

Resumo Fundamento: A função ventricular direita é fator crucial do prognóstico do lúpus eritematoso sistêmico (LES). Objetivos: Avaliar a função ventricular direita em pacientes com LES e diferentes graus de hipertensão pulmonar (HP) por avaliação do strain e do strain rate. Métodos: Um total de 102 pacientes com LES e 30 voluntários sadios foram estudados entre outubro de 2015 e maio de 2016. Os pacientes foram divididos em três grupos de acordo com a pressão sistólica da artéria pulmonar (PSAP) estimada por ecocardiografia: grupo controle (A); PSAP ≤ 30 mmHg (grupo B, n = 37); PSAP 30-50 mmHg (HP leve; grupo C, n = 34); e PSAP ≥ 50 mmHg (HP moderada a grave; grupo D, n = 31). Foram medidos, nos segmentos basal, medial e apical da parede livre do ventrículo direito, o pico sistólico longitudinal (ε) e o strain rate (SR), incluindo o SR sistólico (SRs), o SR diastólico precoce (SRp) e o SR diastólico tardio (SRt) pela técnica de ecocardiografia bidimensional com rastreamento de "pontos" (two-dimensional speckle tracking echocardiography, 2D-STE) pela visualização apical de quatro câmaras. Um p < 0,05 foi adotado como estatisticamente significativo. Resultados: Os parâmetros ε, SRs, SRp e SRt foram significativamente menores nos grupos C e D em comparação aos grupos A e B. O ε de cada segmento foi significativamente menor no grupo D que no grupo C, ao passo que não houve diferença no SRs, SRp ou SRt entre os grupos C e D. Conclusões: O strain e o SR obtidos por 2D-STE puderam detectar precocemente disfunção ventricular direita em pacientes com LES e HP, contribuindo para o tratamento clínico e prognóstico desses pacientes.
