Objective To gain an in-depth understanding of influencing factors on the preventive behaviors of operating room nurses regarding hypothermia during cesarean sections,and to provide references for promoting the prevention of hypothermia during cesarean sections.Methods A descriptive qualitative research approach was adopted,based on the theoretical framework of the Precede-Proceed Model to develop an interview outline.Semi-structured interviews were conducted with 12 operating room nurses,and the interview data were analyzed using directed content analysis.Results The influencing factors were categorized into 3 main themes and 8 sub-themes.①Predisposing factors:insufficient theoretical knowledge,low risk awareness among healthcare providers.②Enabling factors:rational allocation of equipment/resources,proficient operational skills,targeted and effective training programs,and standardized preventive procedures.③Reinforcing factors:the need to enhance team cooperation,the need to improve the regulatory mechanism.Conclusion Nursing managers should strengthen education and training to enhance nurses'awareness and skill levels in preventing hypothermia,improve equipment resources and build an information-based assessment and decision support system to promote the implementation of hypothermia prevention behaviors.Additionally,facilitating team collaboration and utilizing information construction to collect and analyze quality indicators can strengthen quality management and promote continuous improvement in the quality of hypothermia prevention during cesarean sections.

Objective This study aimed to investigate the clinical characteristics of cryptogenic stroke as the first manifestation of occult systemic malignancy (OSM) and to determine whether plasma D-dimer levels and lesions in multiple vascular regions could predict occult systemic malignancy in patients with cryptogenic stroke. Methods Data from 83 patients including 9 patients with OSM and 74 patients without OSM were extracted from the stroke database of Beijing Shijitan Hospital. Clinical variables were analyzed between cryptogenic stroke patients with OSM and without OSM. The relationshiop between plasma D-dimer levels or lesions in multiple vascular regions and OSM were analyzed by multiple logistic regression analysis. Results Compare to patients without OSM, patients with OSM was older (66.8± 7.5 vs.56.4±15.7,P=0.004)and had lower hemoglobin levels (127.9±19.8 vs.143.6±17.7,P=0.015),higher conut score [3(1,3) vs. 1(0,2), P=0.011], higher plasma D-dimer levels (77.7% vs. 13.5%, P<0.001) and more common lesions in multiple vascular regions(100% vs.23.0%, P<0.001).Multiple logistic regression analysis revealed that high plasma D-dimer levels are independent risk factors for OSM (OR=26.250,95%CI:3.041-226.604,P=0.003).Conclusions Patients with OSM are elderly people and have poorer nutritional status, higher plasma D-dimer levels and more common lesions in multiple vascular regions. High plasma D-dimer levels can be useful to predict OSM in patients with cryptogenic stroke at earlier stages.

Objective To compare the differences of clinical and neuroimaging features between ischemic stroke patients with and without cancer. Methods From January 2013 and July 2017, 41 patients with active cancer diagnosed as acute ischemic stroke were retrospectively analyzed as research group. Besides, 41 age-and sex-matched patients diagnosed as acute ischemic stroke without cancer were selected as control group. The clinical date of both groups were collected and analyzed statistically. Results The percentages of hypertension, hyperlipidemia and past stroke were lower (χ2 > 5.549, P < 0.05), and the percentage of patients with cryptogenic stroke was higher in the research group than in the control group (χ2 > 17.537, P < 0.05). The hemoglobin level was lower (t = 4.609, P < 0.001), the D-dimer level was higher (t = -5.796, P < 0.001) in the research group than in the control group. Multiple vascular lesions of 53.7% patients in the research group were higher than 4.9% in the control group. The percentage of DWI lesions involving three vessel territories was higher in the research group than in the control group (χ2 > 17.995, P < 0.01). The percentage of multiple small lesions, and lesions located in cortical/subcortical lesions or cerebellum was higher in the research group than in the control group (χ2 > 8.159, P < 0.01). The 30 days mRS score after ischemic stroke (t = -3.222, P < 0.01) and the mortality rate within 30 days (P < 0.05) were higher in the research group than in the control group. Conclusion Compared with ischemic stroke patients without cancer, there were more cryptogenic stroke, higher D-dimer levels and poor prognosis in patients with active cancer. In ischemic stroke, patients with active cancer has a unique focal distributions characterized by more multiple vascular lesions involving three vessel territories and more lesions located in cortical/subcortical and cerebellum. The patients with ischemic stroke who conform to above characteristic should be paied attention to tumor screening.
