Antenatal urine of 497 pregnant women was collected in the Department of Gynecology and Obstetrics of a county hospital in Jiaozuo, Henan. The content of the main metabolites of synthetic pyrethroid pesticides in urine were determined. After 1 year, physical development indices of 1-year old infants, such as height, weight, and head and chest circumference, were measured. The neural and mental development of the infants was assessed by the Development Screen Test (DST) scale. We observed that the level of synthetic pyrethroid pesticide exposure was negatively related to the neural and mental development of infants (β = -0.1527, P < 0.05). Therefore, direct or indirect exposure to synthetic pyrethroid pesticides should be avoided during pregnancy.
Aim
This study aimed to explore the impact of preceptor clinical teaching behaviours on transition shock in graduate nurses using bi‐directional feedback between graduate nurses and clinical preceptors and to assess preceptor clinical teaching behaviours.
Design
This was a descriptive cross‐sectional study.
Methods
This study was conducted from January‐February 2019. Participants included graduate nurses (N = 117) and clinical preceptors (N = 908) from a major public tertiary hospital in Western China.
Results
Overall level of transition shock of graduate nurses was moderate (mean = 89 SD 17.54). Transition shock level of graduate nurses rose with the increasing of time in clinical work. Intensive care unit graduate nurses suffered the strongest transition shock, whereas surgery graduate nurses suffered the least. Graduate nurses thought that clinical preceptors were best at evaluation and feedback, whereas clinical preceptors thought they were best at showing concern and support. The primary factors associated with transition shock in graduate nurses were the time admitted to the hospital, feedback, and evaluation, use of appropriate teaching strategies, and showing concern and support, explaining 63.5% of the total variation in transition shock in graduate nurses.
Conclusion
In Western China, where the development of economic and medical conditions lag, transition shock is a major obstacle to the professional development of graduate nurses and clinical teaching behaviours is the key to overcoming transition obstacles. However, the serious shortage of nurses makes it difficult to not only complete heavy clinical nursing work but also to undertake the teaching of students and graduate nurses. The clinical teaching system is influenced by many factors. Focusing on clinical teaching behaviours and transition shock in graduate nurses will provide valuable data for future intervention studies.
Implication
The findings of this study will be of interest to managers at all levels and will enable them to support graduate nurses by engaging in excellent clinical teaching behaviours. In the clinical teaching process, giving more feedback and evaluation, improving the ability of using appropriate teaching strategies and focusing on the physical and mental health of graduate nurses may effectively decrease transition shock of graduate nurses and reduce the turnover rate.
Introduction: Evidence supporting non-invasive ventilation (NIV) in paediatric acute respiratory distress syndrome (PARDS) remains sparse. We aimed to describe characteristics of patients with PARDS supported with NIV and risk factors for NIV failure. Materials and Methods: This is a multicentre retrospective study. Only patients supported on NIV with PARDS were included. Data on epidemiology and clinical outcomes were collected. Primary outcome was NIV failure which was defined as escalation to invasive mechanical ventilation within the first 7 days of PARDS. Patients in the NIV success and failure groups were compared. Results: There were 303 patients with PARDS; 53/303 (17.5%) patients were supported with NIV. The median age was 50.7 (interquartile range: 15.7-111.9) months. The Paediatric Logistic Organ Dysfunction score and oxygen saturation/fraction of inspired oxygen (SF) ratio were 2.0 (1.0-10.0) and 155.0 (119.4-187.3), respectively. Indications for NIV use were increased work of breathing (26/53 [49.1%]) and hypoxia (22/53 [41.5%]). Overall NIV failure rate was 77.4% (41/53). All patients with sepsis who developed PARDS experienced NIV failure. NIV failure was associated with an increased median paediatric intensive care unit stay (15.0 [9.5-26.5] vs 4.5 [3.0-6.8] days; P <0.001) and hospital length of stay (26.0 [17.0-39.0] days vs 10.5 [5.5-22.3] days; P = 0.004). Overall mortality rate was 32.1% (17/53). Conclusion: The use of NIV in children with PARDS was associated with high failure rate. As such, future studies should examine the optimal selection criteria for NIV use in these children.

Background:
Group A β-hemolytic streptococcus (GAS) and Group B streptococcus (GBS) are two common pathogens that are associated with many diseases in children. Severe infections as a result of these two streptococci are albeit uncommon but associated with high mortality and morbidity, and often necessitate intensive care support. This paper aims to review mortality and morbidity severe infection associated with GAS and GBS isolations at a Pediatric Intensive Care Unit (PICU).
Methods:
All children admitted to PICU of a teaching hospital between October 2002 and May 2018 with laboratory-proven GAS and GBS isolations were included.
Results:
There were 19 patients (0.7% PICU admissions) with streptococcal isolations (GAS, n=11 and GBS, n=8). Comparing to GAS, GBS affected infants were younger (median age 0.13 versus 5.47 years, 95% CI, 1.7-8.5, p=0.0003), and cerebrospinal fluids more likely positive (p = 0.0181). All GAS and GBS were sensitive to penicillin (CLSI: MICs 0.06 – 2.0 μg/mL), with majority of GAS sensitive to clindamycin and erythromycin, and half of the GBS resistant to clindamycin and erythromycin. Co-infections were prevalent, but viruses were only isolated with GAS (p=0.024). Isolation of GAS and GBS was associated with nearly 40% mortality and high rates of mechanical ventilation and inotropic supports. All non-survivors had high mortality (PIM2) and sepsis scores.
Conclusions:
Severe GAS and GBS are rare but associated with high mortality and rates of mechanical ventilation and inotropic supports in PICU. The streptococci are invariably sensitive to penicillin. The high PIM2 and Sepsis scores suggest that prompt recognition of sepsis and timely judicious institution of antibiotics and intensive care support may be life-saving for these devastating infections.
