BackgroundSelf-medication with antibiotics (SMA) has been reported among university students in many countries, but little research has been done on this issue in China. The objective of this study was to evaluate knowledge and behaviors of university students and risk factors concerning SMA.Methodology/Principal FindingsUsing a novel questionnaire-based data collection instrument, an anonymous online survey was conducted with the students of Shantou University (STU), a university comprising 8 schools/colleges in eastern Guangdong, China. Of 1,300 respondents (13.8% of total eligible participants), 47.8% had self-treated with antibiotics. Logistic regression analysis identified prior knowledge of antibiotics (PKA), older age, and higher monthly allowance as independent risk factors for SMA. PKA significantly influenced students' knowledge about antibiotics, their uses, and common adverse reactions (all p<0.05). Among self-medicated students, 61.7% used antibiotics at least twice in the previous year. Community pharmacies were the major source of self-prescribed antibiotics. Reported common indications for SMA were sore throat (59.7%), fever (38.2%), cough (37.4%), runny nose (29.3%), and nasal congestion (28.7%). While 74.1% of self-medication episodes were based on students' own experiences, only 31.1% of students claimed to understand the package insert. Alteration of antibiotics and dosage during the course of self-treatment was made by 63.8% and 55.6% of students, respectively. At least two kinds of antibiotics were simultaneously taken by 82.6% of students. The majority of self-medicated students failed to complete the course of antibiotics. Adverse reactions were reported by 16.3% of students. Amoxicillin was the most common antibiotic used for self-medication.ConclusionsHigh prevalence of SMA was noted among STU students. Presence of risk factors and risk-associated behaviors/attitudes in the study population calls for focused educational intervention and stricter governmental legislation and regulation of antibiotic use and sale in pharmacies.

BackgroundAcute respiratory infections (ARIs) are common in children and mostly caused by viruses, but the significance of the detection of multiple viruses in ARIs is unclear. This study investigated 14 respiratory viruses in ARIs among children and associated meteorological factors in Shantou, southern China.MethodsPaired nasal/throat-flocked swabs collected from 1,074 children with ARIs, who visited outpatient walk-in clinics in a tertiary hospital between December 2010 and November 2011, were examined for fourteen respiratory viruses - influenza viruses (FluA, FluB), respiratory syncytial viruses (RSV A and B), human coronaviruses (hCoV: 229E, OC43, HKU1, NL63), human metapneumoviruses (hMPV A and B), parainfluenza viruses (PIV1-4), human rhinoviruses (HRV A, B, C), enteroviruses (EV), adenoviruses (ADV), human bocavirus (hBoV), and human parechoviruses (hPeV) - by multiplex real-time PCR.ResultsWe identified at least one virus in 82.3% (884/1,074) and multiple viruses in 38.6% (415/1,074) of patients. EV and HRV were the most frequently detected single viruses (42.3%, 374/884 and 39.9%, 353/884 respectively) and co-detected pair (23.1%, 96/415). Overlapping seasonal trends of viruses were recorded over the year, with dual peaks for EV and single peaks for the others. By logistic regression analysis, EV was positively associated with the average temperature and humidity, hCoV, and PIV4, but negatively with HRV, PIV3, and hBoV. HRV was inversely associated with EV and PIV3.ConclusionsThis study reports high viral detection and co-detection rates in pediatric ARI cases mainly due to EV and HRV. Many viruses circulated throughout the year with similar seasonal trends in association with temperature, humidity, and wind velocity. Statistically significant associations were present among the viruses. Understanding the polyviral etiology and viral interactions in the cases with multiple viruses warrants further studies.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-015-0863-6) contains supplementary material, which is available to authorized users.

Introduction: This study investigated the current state of attitudes, behaviors, and knowledge concerning sex and sexually transmitted infections (STIs) among Chinese university students. Methodology: A cross-sectional anonymous university intranet-based survey was given to students attending the Shantou University, Guangdong, China using a 28-item questionnaire. Results: Of 3425 website visitors, 1030 university students completed the survey, of which 80% were between 20 and 25 years of age, 76% considered pre-marital sex acceptable, 21% had had sexual intercourse, and 45% of sexually active students had engaged in oral sex, anal intercourse, or sex with strangers. Students had limited knowledge and awareness about common STIs, symptoms, and complications. Three percent of the sexually active students reported having had STIs and another 8% were not sure whether they had or not. Most students had misconceptions about transmission and prevention of STIs. The internet was the main information resource for 76% of students. Conclusions: Despite having more open attitudes and behaviors towards sex, students' STI knowledge and awareness of STI risks was considerably limited, raising concerns about a likely rise in STI incidence. Prior knowledge of STIs had no significant influence. Targeted educational measures such as online education and counseling via Chinese websites and social media, and the provision of safer sex and STIrelated information by health experts to university students are suggested.

Introduction: Health-care associated infections (HCAIs) occur worldwide and affect both patients and health-care workers (HCWs), including medical students. This study aimed to investigate HCAI risks associated with clinical medical students attending Shantou University Medical College (SUMC) and the effectiveness of their learning resources. Methodology: Four cohorts (n = 272) of medical students participated in a questionnaire-based survey was done on (year 5 in the 5-year program and years 5 to 7 in the 7-year program) undergoing internship training in 14 teaching hospitals in Guangdong, China. Results: The mean overall score of the students was 52.54 ± 0.45 (mean ± SE). Students received fairly good scores in hand hygiene (77.57 ± 0.77) and HCAI source (63.16 ± 1.18); relatively weak scores in the isolation precautions (44.59 ± 0.55), HCW safety (45.59 ± 0.86), and personal protective equipment (57.64 ± 0.60); and the weakest scores in HCA-pathogen identification (27.44 ± 0.81). The year of education (r = 0.089, P = 0.144, n = 272) or internship placement (r = 0.077, P = 0.206, n = 272) had no significant influence on their level of knowledge. Conclusions: This study demonstrates that medical students at SUMC have limited knowledge and practice regarding HCAI due to substantial deficiencies in their learning resources. Review of medical curricula, improvement in preclinical and clinical training, and surveillance and monitoring of practicing HCWs are urgently needed to minimize risk of HCAIs in patients and HCWs.

This multicenter study evaluated the quality of life (QOL) of patients with advanced cancer and assessed the improvement in patients' QOL by hospice service program, using McGill Quality of Life Questionnaire-Hong Kong version (MQOL-HK) questionnaire in China's 32 hospice centers from March to June, 2012. Among 640 recruited cases, data of 630 patients were analyzed. Differences in patients' pre- and posthospice QOL were evaluated. Compared to prehospice results, patients' QOL scores improved significantly in physical, psychological, existential, and support domains after 3 weeks of hospice services. Some items were not thus classified primarily due to cross-cultural adaptation. The MQOL-HK questionnaire could effectively measure QOL in Chinese hospice patients and their QOL could be improved by hospice services. Psychological, existential, and support services should be emphasized during patients' initial 3 weeks of hospice admission.
