Emergence of multiple fluconazole-resistant Candida parapsilosis sensu stricto clones with persistence and transmission in China.

OBJECTIVES: We explored the epidemiological and molecular characteristics of Candida parapsilosis sensu stricto isolates in China, and their mechanisms of azole resistance. METHODS: Azole susceptibilities of 2318 non-duplicate isolates were determined using CLSI broth microdilution. Isolates were genotyped by a microsatellite typing method. Molecular resistance mechanisms were also studied and functionally validated by CRISPR/Cas9-based genetic alterations. RESULTS: Fluconazole resistance occurred in 2.4% (n = 56) of isolates, and these isolates showed a higher frequency of distribution in ICU inpatients compared with susceptible isolates (48.2%, n = 27/56 versus 27.8%, 613/2208; P = 0.019). Microsatellite-genotyping analysis yielded 29 genotypes among 56 fluconazole-resistant isolates, of which 10 genotypes, including 37 isolates, belonged to clusters, persisting and transmitting in Chinese hospitals for 1-29 months. Clusters harbouring Erg11Y132F (5/10; 50%) were predominant in China. Among these, the second most dominant cluster MT07, including seven isolates, characteristically harbouring Erg11Y132F and Mrr1Q625K, lent its carriage to being one of the strongest associations with cross-resistance and high MICs of fluconazole (>256 mg/L) and voriconazole (2-8 mg/L), causing transmission across two hospitals. Among mutations tested, Mrr1Q625K led to the highest-level increase of fluconazole MIC (32-fold), while mutations located within or near the predicted transcription factor domain of Tac1 (D440Y, T492M and L518F) conferred cross-resistance to azoles. CONCLUSIONS: This study is the first Chinese report of persistence and transmissions of multiple fluconazole-resistant C. parapsilosis sensu stricto clones harbouring Erg11Y132F, and the first demonstration of the mutations Erg11G307A, Mrr1Q625K, Tac1L263S, Tac1D440Y and Tac1T492M as conferring resistance to azoles.

High Prevalence of Carbapenem-Resistant Enterobacterales Colonization Among Intensive Care Unit Patients in a Tertiary Hospital, China.

Intestinal colonization with carbapenem-resistant Enterobacterales (CRE) has been shown as a significant risk factor for subsequent CRE infections, especially in intensive care units (ICUs). The aim of this study was to determine the prevalence of intestinal CRE colonization among ICU patients in a Chinese tertiary hospital. Fecal sample screenings for CRE were performed on ICU patients weekly. Antibiotic-susceptibility profile of CRE strains was determined using the Vitek-2 analysis system and broth microdilution method. The carbapenemases of all isolates were determined by phenotypes and genotypes. Clonal relatedness was analyzed by pulsed-field gel electrophoresis (PFGE). Whole-genome sequencing was used to identify the multilocus sequence type (ST), plasmid replicons, and insertion sequences (ISs) of isolates. The overall colonization rate of CRE was 40.4% (82/203). A total of 84 CRE strains were detected, mostly with Klebsiella pneumoniae (92.9%). Antibiotic susceptibility testing profile revealed that 84 CRE strains were resistant to most antibiotics except for tigecycline and colistin. The carbapenemase-encoding genes including blaKPC-2, blaNDM-1, and blaIMP-4 were detected, and blaKPC-2 was the predominant genotype (90.8%). A total of 9 STs were identified among 84 CRE strains, and ST11 was the most common type (83.3%). A variety of mobile genetic elements, including plasmids and ISs, were detected via online tool prediction. PFGE analysis of the 78 K. pneumoniae strains showed 8 different pulsotypes, and pulsotype A was highly prevalent. This study found that the prevalence of CRE colonization was alarmingly high in the ICU, and that effective infection control measures are urgently needed to prevent the dissemination of CRE.

Psychological and mental health impacts of COVID-19 pandemic on healthcare workers in China: A review.

The coronavirus disease-19 (COVID-19) pandemic has put healthcare workers in an unprecedented situation, increasing their psychological and mental health distress. Much research has focused on the issues surrounding anxiety, depression, and stress among healthcare workers. The consequences of mental health problems on healthcare workers' physical health, health-compromising behaviours, suicide ideation, family relationships, and job satisfaction during the COVID-19 pandemic are not well studied. Enhanced psychological stress has known effects on an individual's physical health. In healthcare workers with pre-existing comorbidities, psychological stressors may exacerbate their current health problems. Healthcare professionals are known to have a high risk of substance use, hence they may be at risk of development of substance use addiction or vulnerable to addiction relapse. Frontline COVID-19 healthcare workers are being pushed above and beyond their limits, possibly resulting in suicidal tendencies. Furthermore, the burden of high workload and burnout may also have serious manifestations in relationships with family and an intention to quit their jobs. Future studies should explore the above-mentioned deleterious consequences to provide insight into the development of mental healthcare strategies to combat the psychological impact of COVID-19 on healthcare workers during the COVID-19 emergency. It is imperative to employ strategies to care for and policies to protect the psychological well-being of healthcare workers.

Explore the genetics of weedy traits using rice 3K database.

BACKGROUND: Weedy rice, a conspecific weedy counterpart of the cultivated rice (Oryza sativa L.), has been problematic in rice-production area worldwide. Although we started to know about the origin of some weedy traits for some rice-growing regions, an overall assessment of weedy trait-related loci was not yet available. On the other hand, the advances in sequencing technologies, together with community efforts, have made publicly available a large amount of genomic data. Given the availability of public data and the need of "weedy" allele mining for a better management of weedy rice, the objective of the present study was to explore the genetic architecture of weedy traits based on publicly available data, mainly from the 3000 Rice Genome Project (3K-RGP). RESULTS: Based on the results of population structure analysis, we have selected 1378 individuals from four sub-populations (aus, indica, temperate japonica, tropical japonica) without admixed genomic composition for genome-wide association analysis (GWAS). Five traits were investigated: awn color, seed shattering, seed threshability, seed coat color, and seedling height. GWAS was conducted for each sub-population × trait combination and we have identified 66 population-specific trait-associated SNPs. Eleven significant SNPs fell into an annotated gene and four other SNPs were close to a putative candidate gene (± 25 kb). SNPs located in or close to Rc were particularly predictive of the occurrence of seed coat color and our results showed that different sub-populations required different SNPs for a better seed coat color prediction. We compared the data of 3K-RGP to a publicly available weedy rice dataset. The profile of allele frequency, phenotype-genotype segregation of target SNP, as well as GWAS results for the presence and absence of awns diverged between the two sets of data. CONCLUSIONS: The genotype of trait-associated SNPs identified in this study, especially those located in or close to Rc, can be developed to diagnostic SNPs to trace the origin of weedy trait occurred in the field. The difference of results from the two publicly available datasets used in this study emphasized the importance of laboratory experiments to confirm the allele mining results based on publicly available data.

["Arrhythmia Reading": A Diverse Teaching Approach to Improve the Ability of 2 Year NPGY Nurses to Interpret and Manage Arrhythmias].

BACKGROUND: The author of this paper works in the critical care ward of an internal medicine department. During the study period, current trainees in a nurse post graduate year (NPGY) program joined our nurse team. While at our ward, they were required to demonstrate clinical nursing competencies in intensive care units in the facets of nursing knowledge, equipment use, prediction of emergencies, emergency response, and patient evaluation and management. The ability to interpret arrhythmias is critical to connecting and coordinating these competencies. However, arrhythmia interpretation is usually the most difficult skill for nurses to master. PURPOSE: This study was developed to improve the knowledge of NPGY trainees regarding arrhythmia interpretation, the accuracy of their arrhythmia interpretation and management, and their confidence in caring for patients with arrhythmia. RESOLUTION: The period of this study spanned from April 5th to June 18th, 2018. After surveying the current capabilities of the NPGY trainees to provide a reference for improvement, several teaching strategies were adopted. These strategies included: (1) provision of arrhythmia clinical scenarios; (2) establishment of multimedia teaching and interactive e-books; (3) development of memory strategies; and (4) mind mapping. RESULTS: The accuracy of the trainees' knowledge regarding arrhythmia interpretation increased from 52.5% pretest to 92.5% posttest, while their arrhythmia interpretation skill improved from 56.3% pretest to 92.5% posttest. Furthermore, their caring-for-patients-with-arrhythmia confidence score increased from 5.5 to 9.1. All of the objectives of this study were achieved. CONCLUSIONS: The diverse teaching approach employed in this study enhanced the ability of trainees to remember and recall relevant theories as well as improved their related practical skills. Furthermore, posttest, the trainees were significantly less nervous during encounters with patients with arrhythmia and demonstrated improved problem-solving abilities. Participation in this intervention significantly improved the confidence of trainees to serve as critical care nurses and to pursue a career in critical care nursing.

The experiences of women who quit smoking during pregnancy and how they dealt with their spouses' continued smoking.

OBJECTIVE: to explore how pregnant women in Taiwan dealt with their spouses who continued to smoke and with passive smoking during their own process of quitting and abstaining. DESIGN: a qualitative study using an oral history approach. Data were collected via tape-recorded open-ended interviews. All interviews were transcribed verbatim. Data were analysed using narrative analysis. SETTING: the homes of the participant women living in the district of a regional hospital of eastern Taiwan. PARTICIPANTS: a purposive sample of 10 Taiwanese women who had quit smoking while pregnant was recruited at 1-3 months following the birth of their infants. FINDINGS: five major themes emerged: (1) the women coping with tobacco addiction on their own, (2) creating a non-smoking section or environment at home, (3) dealing with passive smoking, (4) conflict over the wife's sensitivity to her spouse's residual tobacco smell, and (5) allowing the husband to continue smoking to avoid conflicts. KEY CONCLUSIONS: the pregnant women were expected by their spouses to quit smoking, yet the husbands continued to smoke. Women had to struggle to quit smoking on their own. The findings from this study support the need to listen to pregnant women's stories, as this is paramount to understanding their experiences of tobacco-use reduction and cessation, and for developing gender appropriate interventions to support their efforts. IMPLICATIONS FOR PRACTICE: health care providers should encourage and help pregnant women who are willing to quit smoking. This help could be more family-centred instead of focusing on the pregnant women alone, and therefore involve educating the spouse to support his wife.

[Constructing a baby-friendly community].

The Baby-Friendly Hospital Initiative (BFHI), developed by the World Health Organization and the United Nations Children's Fund to promote breastfeeding in maternity facilities worldwide, has had a global impact on breastfeeding outcomes. However, further interventions are necessary before and after hospital discharge to meet the initiative's recommended 6-month targets. The Baby-Friendly Community Initiative (BFCI), a multifaceted program for community based breastfeeding promotion designed to complement BFHI, addresses this challenge. The purpose of this paper is to introduce the origin of BFCI and its current implementation status in several countries as a reference for effective BFCI promotion in Taiwan.

Effects of a pushing intervention on pain, fatigue and birthing experiences among Taiwanese women during the second stage of labour.

OBJECTIVES: To evaluate maternal labour pain, fatigue, duration of the second stage of labour, the women's bearing-down experiences and the newborn infant Apgar scores when spontaneous pushing is used in an upright position. DESIGN: Quasi-experimental study. SETTING: Medical centre in Taichung, Taiwan. PARTICIPANTS: 66 Women giving birth at the hospital, with 33 primigravidas assigned to each group. INTERVENTIONS: During the second stage of labour, the women in the experimental group pushed from an upright position and were given support to push spontaneously; the women in the control group pushed from a supine position and were supported via Valsalva pushing. OUTCOME MEASURES: Pain scores were recorded at two evaluation time points: at 10 cm of cervical dilation and one hour after the first pain score evaluation. One to four hours after childbirth, the trained nurses collected the fatigue and pushing experience scores. FINDINGS: The women in the experimental group had a lower pain index (5.67 versus 7.15, p = 0.01), lower feelings of fatigue post birth (53.91 versus 69.39, p < 0.001), a shorter duration of the second stage of labour (91.0 versus 145.97, p = 0.02) and more positive labour experiences (39.88 versus 29.64, p < 0.001) compared with the control group. There was no significant difference in the Apgar score for newborn infants during either the first minute (7.70 versus 7.73, p = 0.72) or the fifth minute (8.91 versus 8.94, p = 0.64). KEY CONCLUSIONS: The pushing intervention during the second stage of labour lessened pain and fatigue, shortened the pushing time and enhanced the pushing experience. IMPLICATIONS FOR PRACTICE: Pushing interventions can yield increased satisfaction levels for women giving birth.
