Spatiotemporal variation in precipitation during rainy season in Beibu Gulf, South China, from 1961 to 2016

The spatiotemporal variation in precipitation is an important part of water cycle change, which is directly associatedwith the atmospheric environment and climate change. The high-resolution spatiotemporal change of precipitation is still unknown inmany areas despite its importance. This study analyzed the spatiotemporal variation in precipitation in Beibu Gulf, South China, during the rainy season (fromApril to September) in the period of 1961–2016. The precipitation datawere collected from 12 national standard rain-gauge observation stations. The spatiotemporal variation in precipitation was evaluated with incidence rate and contribution rate of precipitation. The tendency of variations was analyzed using the Mann–Kendall method. The precipitation in the rainy season contributed 80% to the total annual precipitation. In general, there was an exponential decreasing tendency between the precipitation incidence rate and increased precipitation durations. The corresponding contribution rate showed a downward trend after an initial increase. The precipitation incidence rate decreased with the rising precipitation grades, with a gradual increase in contribution rate. The precipitation incidence rate and contribution rate of 7–9 d durations showed the significant downward trends that passed the 95% level of significance test. The results provide a new understanding of precipitation change in the last five decades, which is valuable for predicting future climate change and extreme weather prevention and mitigation

Patient-centred care and patient autonomy: doctors' views in Chinese hospitals

Background: Patient-centred care and patient autonomy is one of the key factors to better quality of service provision, hence patient outcomes. It enables the development of patients’ trusts which is an important element to a better doctor-patient relationship. Given the increasing number of patient disputes and conflicts between patients and doctors in Chinese public hospital, it is timely to ensure patient-centred care is fully and successfully implemented. However, limited studies have examined the views and practice in different aspects of patient-centred care among doctors in the Chinese public hospitals. Methods: A quantitative approach was adopted by distributing paper-based questionnaires to doctors and patients in two hospitals (Level III and Level II) in Jinan, Shandong province, China. Results: In total, 614 doctors from the surgical and internal medicine units of the two hospitals participated in the survey yielding 90% response rates. The study confirmed the inconsistent views among doctors in terms of their perception and practice in various aspects patient-centred care and patient autonomy regardless of the hospital where they work (category II or category III), their unit speciality (surgical or non-surgical), their gender or seniority. The high proportion of doctors (more than 20%) who did not perceive the importance of patient consultation prior to determining diagnostic and treatment procedure is alarming. This in in part due to the belief held by more than half of the doctors that patients were unable to make rational decisions and their involvement in treatment planning process did not necessarily lead to better treatment outcomes. Conclusion: The study calls for the development of system level policy and organisation wide strategies in encouraging and enabling the practice of patient-centred care and patient autonomy with the purposes of improving the quality of the service provided to patients by Chinese hospitals

Doctors in Chinese public hospitals: demonstration of their professional identities

Background: An increase in the number of medical disputes and violence against doctors indicates a lack of trust in the medical profession by society in Chinese public hospitals. Empirical evidence confirms that one cause is the lack of professional identity demonstrated by doctors. Medical professionals are required to maintain high standards of competence and moral responsibility, and demonstrate qualities such as respect, compassion, integrity, responsiveness to needs, and commitment to sound ethical practice in order to maintain professional privilege. These principles and appropriate professional conduct are the foundation of the professional identity of the medical profession. Methods: A quantitative approach was adopted by distributing paper-based questionnaires to doctors and patients in two hospitals (Level III and Level II) in Jinan, Shandong province, China. Findings: In total, 614 doctors and 1184 inpatients on discharge from the surgical and internal medicine units of the two hospitals participated in the survey yielding 90% response rates. The study confirmed the variation amongst doctors in demonstrating their professionalism in terms of respecting patients’ views and preferences when determining diagnostic procedures and treatment plans, and when making ethical decisions. Although 90% patients indicated that they showed respects to doctors, close to 20% of the doctors disagreed that they received high respect from patients. About 12% of doctors prescribed unnecessary diagnostic procedures to patient for the purpose of generating profit and more than 20% of patients indicated that they gave gifts to doctors in order to receive better treatment. Conclusions: Although about 80% of doctors demonstrated certain aspects of professionalism required by practitioners, the inconsistency across the medical workforce may exacerbate tense doctor-patient relationships. A review of medical curricula and focus of the internship program is required in order to assist medical graduates with forming required professional identity in order to improve patient satisfaction and better clinical outcomes. To be effective, a more systematic approach is recommended

General wellbeing and work impacts among community pharmacists during crisis management

Background: Community pharmacists are highly accessible for advice, as most pharmacies are open long hours and no appointment is needed. Community pharmacists, as essential community health workers, play a critical role in the fight against coronavirus disease 2019 (COVID-19). This study aimed to determine the general wellbeing and work impacts of pharmacists and the factors important for adaptability and resilience during the COVID-19 pandemic. Methods: This study adopted a cross-sectional design. Community pharmacists from various professional networks in Australia were invited through emails and social media posts to complete an anonymous online survey during the second wave of the COVID-19 pandemic in Victoria, Australia. Results: Sixty-five community pharmacists completed the online survey. The respondents reported fair levels of general wellbeing during the COVID-19 pandemic, with a mean self-related health score of 33.57 (s.d. = 13.19) out of a maximal of 96, despite relatively high levels of job stress and emotional labour. Lower levels of general wellbeing were correlated with higher levels of job stress (r = 0.645, P < 0.01) and emotional labour (r = 0.513, P < 0.01), and lower levels of occupational self-efficacy (r = −0.566, P < 0.01). Leader member exchange was negatively correlated with job stress (r = −0.419, P < 0.01) and positively correlated with psychological safety (r = 0.693, P < 0.01). The linear regression models showed that female pharmacists had lower occupational self-efficacy (β = −0.286, P = 0.024), but higher psychological safety (β = 0.234, P = 0.042). Higher work ability was associated with lower job stress (β = −0.529, P < 0.001), higher occupational self-efficacy (β = 0.511, P = 0.001), and poorer self-related health (β = −0.659, P < 0.001). Conclusions: The findings highlight the importance of a supportive work environment in helping community pharmacists to feel psychologically safe and reduce stress during a crisis

Adaptation strategies in transnational education: a case study of an Australian Master of Health Administration Course offered to Chinese managers

Background: Management decisions in health influence patient care outcomes; however, health management development courses in China are rare. This study aims to document and evaluate a transnational Master of Health Administration (MHA) course launched in 2000 for the benefit of Chinese health managers. Methods: A case study of the MHA program jointly run by an Australian university and a Chinese Medical University was conducted. We reviewed the development of the MHA course through a document analysis (key events recorded in achieves, minutes, and audits) followed by reflection (by two course coordinators), extracting key themes related to adaptative strategies. We then conducted a questionnaire survey of 139 graduates seeking their views on relevance, satisfaction and challenges associated with each subject within the course, the relevance of key management skills (as determined by the Australasian College of Health Service Management competency framework), and the impact of the course on their personal career trajectories. Chi-square tests identified differences in the responses by age, gender, pre-training position, and current workplace. Results: The curriculum pedagogy followed the principles of practice-based reflective learning. Research findings and student feedback shaped the curriculum design and subject content, to enhance management practices of the students. Survey participants expressed high levels of satisfaction and confirmed the relevance of all study subjects. Two subjects, health economics and data management, were perceived as being the most challenging. Of the ten management skills we assessed, relatively low self-rated confidence was found in “strategic thinking” and “planning”. Younger and less experienced graduates were more likely to report learning challenges (p < 0.05). Frontline managers were least likely to obtain promotion by changing employers (χ2 = 6.02, p < 0.05) or being seconded to another position (χ2 = 9.41, p < 0.01). Conclusions: This case study illustrates the suitability of cross-country partnerships in health management training, which offers opportunities for managers to systematically explore and acquire a comprehensive set of management skills applicable to their career needs. Opportunities for developing training aligned to career development opportunities are critical for attracting and developing a competent and well-prepared health service management workforce in China

Managers in the publicly funded health services in China - characteristics and responsibilities

Background: Health service managers are integral to supporting the effective and efficient delivery of services. Understanding their competencies is essential to support reform and improvement of healthcare provision in China. This paper examines the characteristics and educational background of senior managers working in the community health and hospital sectors in China. We also examine their levels of commitment to continued professional development and continuous education. Methods: A self-administered paper-based questionnaire was administered to 477 level I, II and III managers in community health services and public hospitals in China. The response rate was over 80%. Results: Findings demonstrate significant differences in terms of educational background and commitment to ongoing professional development between the managers in China across levels of management, and between the community and hospital sectors. Hospital managers tend to be older; hospital managers at higher management levels are predominantly male but predominantly female in the community health services. A greater proportion of hospital managers have postgraduate qualifications. In addition, the participants identified specific management tasks that they considered important. Conclusions: This is the first large scale study examining the educational background and commitment to professional development of senior health service managers in China. This study determined that there are differences between the demographics of managers in China across levels of management, but more importantly between the CHC and the hospital sectors. The identification of important managerial tasks will facilitate the development of appropriate education and training for Chinese healthcare managers. All sectors and levels reported the need for informal education focussed on the core roles of developing organisation image and public relations, improving quality and safety of service provision and provision of leadership. Further research to explore the underlying reasons for the above differences is needed to design appropriate professional development for China's health services managers. In addition, the importance of managerial tasks across sectors and management levels requires further investigation

Extracellular volume quantitation using dual-energy CT in patients with heart failure: Comparison with 3T cardiac MR

Backgrounds: Cardiac magnetic resonance (CMR) T1 mapping and the extracellular volume (ECV) have been developed to quantitative analysis of diffusely abnormal myocardial fibrosis (MF). However, dual-energy CT (DECT) has a potential for calculation of ECV. The aim of this study is to evaluate the feasibility and accuracy of DECT technique in determining the ECV in patients with heart failure, with 3T CMR as the reference. Methods: Thirty-five patients with various reasons of heart failure were enrolled in this study. Both DECT and CMR exams were completed within 24 h. ECVs were calculated, and the relationship between DECT-ECV, CMR-ECV, and other heart function parameters, including left ventricular end systolic and diastolic volume, cardiac output and ejection fraction(LVESV, LVEDV, CO, LVEF), Brain natriuretic peptide (BNP) was determined. All participants gave informed consent, and the study was approved by the institutional review board. Results: The median ECVs on DECT and CMR were 33% (95%CI: 32%–36%) and 30% (95%CI: 30% - 32%), respectively. A good correlation between myocardial ECV at DECT and that at CMR (r = 0.945, P < 0.001) was observed. Bland-Altman analysis between DECT and CMR showed a small bias (2.6%), with 95% limits of agreement of −0.4% and 5.6%. Interobserver agreement for ECV at DECT was excellent (ICC = 0.907). Both ECVs, for DECT and CMR, were inversely associated with LVEF and CO. Conclusion: DECT-based ECV could be an alternative non-invasive imaging tool for myocardial tissue characterization. However, overestimation of the extent of diffuse MF is observed with use of DECT

PigBiobank: a valuable resource for understanding genetic and biological mechanisms of diverse complex traits in pigs

To fully unlock the potential of pigs as both agricultural species for animal-based protein food and biomedical models for human biology and disease, a comprehensive understanding of molecular and cellular mechanisms underlying various complex phenotypes in pigs and how the findings can be translated to other species, especially humans, are urgently needed. Here, within the Farm animal Genotype-Tissue Expression (FarmGTEx) project, we build the PigBiobank (http://pigbiobank.farmgtex.org) to systematically investigate the relationships among genomic variants, regulatory elements, genes, molecular networks, tissues and complex traits in pigs. This first version of the PigBiobank curates 71 885 pigs with both genotypes and phenotypes from over 100 pig breeds worldwide, covering 264 distinct complex traits. The PigBiobank has the following functions: (i) imputed sequence-based genotype-phenotype associations via a standardized and uniform pipeline, (ii) molecular and cellular mechanisms underlying trait-associations via integrating multi-omics data, (iii) cross-species gene mapping of complex traits via transcriptome-wide association studies, and (iv) high-quality results display and visualization. The PigBiobank will be updated timely with the development of the FarmGTEx-PigGTEx project, serving as an open-access and easy-to-use resource for genetically and biologically dissecting complex traits in pigs and translating the findings to other species.National Natural Science Foundation of China [32022078]; National Key R&D Program of China [2022YFF1000900]; Local Innovative and Research Teams Project of Guangdong Province [2019BT02N630]; China Agriculture Research System [CARS-35].

Quantitative analysis of late gadolinium enhancement in hypertrophic cardiomyopathy: comparison of diagnostic performance in myocardial fibrosis between gadobutrol and gadopentetate dimeglumine

The purpose of this study was to compare different semi-automated late gadolinium enhancement (LGE) quantification techniques using gadobutrol and gadopentetate dimeglumine contrast agents with regard to the diagnosis of fibrotic myocardium in patients with hypertrophic cardiomyopathy (HCM). Thirty patients with HCM underwent two cardiac MRI protocols with use of gadobutrol and gadopentetate dimeglumine. Contrast-tonoise ratio (CNR) between LGE area and remote myocardium (CNRremote), between LGE area and left ventricular blood pool (CNRpool), and signal-to-noise ratio (SNR) in LGE were compared. The presence and quantity of LGE were determined by visual assessment. With signal threshold versus reference mean (STRM) based thresholds of 2 SD, 5 SD, and 6 SD above the mean signal intensity (SI) of reference myocardium, the full-width at half-maximum (FWHM) technique was used. The volume and segments of the LGE area were compared between the two types of contrast agents. LGE was present in 26 of 30 (86.6%) patients in both protocols. The CNRremote of fibrotic myocardium in gadobutrol and gadopentetate dimeglumine agents was 26.82 ± 14.24 and 21.46 ± 10.59, respectively (P &lt; 0.05). The CNRpool was significantly higher in gadobutrol (9.32 ± 7.64 vs. 6.39 ± 6.11, P &lt; 0.05). The SNR was higher in gadobutrol (33.36 ± 14.35 vs. 27.53 ± 10.91, P &lt; 0.05). The volume of scar size in MR images acquired with gadobutrol were significantly higher than those with gadopentetate dimeglumine (P &lt; 0.05), and the STRM of 5 SD technique showed the greatest agreement with visual assessment (ICC = 0.99) in both examinations. There was no significant difference in fibrotic segments of the fibrotic myocardium in the LGE area (P &lt; 0.05). This study proved that the Gadobutrol was an effective contrast agent for LGE imaging with superior delineation of fibrotic myocardium as compared to gadopentetate dimeglumine. The 5 SD technique yields the closest approximation of the extent of LGE identified by visual assessment

Clinical value of patient-specific three-dimensional printing of congenital heart disease: Quantitative and qualitative assessments

Objective: Current diagnostic assessment tools remain suboptimal in demonstrating complex morphology of congenital heart disease (CHD). This limitation has posed several challenges in preoperative planning, communication in medical practice, and medical education. This study aims to investigate the dimensional accuracy and the clinical value of 3D printed model of CHD in the above three areas. Methods: Using cardiac computed tomography angiography (CCTA) data, a patient-specific 3D model of a 20-month-old boy with double outlet right ventricle was printed in Tango Plus material. Pearson correlation coefficient was used to evaluate correlation of the quantitative measurements taken at analogous anatomical locations between the CCTA images pre- and post-3D printing. Qualitative analysis was conducted by distributing surveys to six health professionals (two radiologists, two cardiologists and two cardiac surgeons) and three medical academics to assess the clinical value of the 3D printed model in these three areas. Results: Excellent correlation (r = 0.99) was noted in the measurements between CCTA and 3D printed model, with a mean difference of 0.23 mm. Four out of six health professionals found the model to be useful in facilitating preoperative planning, while all of them thought that the model would be invaluable in enhancing patient-doctor communication. All three medical academics found the model to be helpful in teaching, and thought that the students will be able to learn the pathology quicker with better understanding. Conclusion: The complex cardiac anatomy can be accurately replicated in flexible material using 3D printing technology. 3D printed heart models could serve as an excellent tool in facilitating preoperative planning, communication in medical practice, and medical education, although further studies with inclusion of more clinical cases are needed
