Discharge preparation experiences and needs of intergenerational caregivers of neonatal intensive care unit preterm: A qualitative study.

PURPOSE: This study aimed to explore the real experiences and needs of neonatal intensive care unit (NICU) preterm intergenerational caregivers for discharge preparation and provide a basis for nursing staff to formulate systemic and personalized health education plans and continuous nursing plans for preterm discharge. DESIGN AND METHODS: This was a descriptive qualitative study. An objective sampling method was used to select 16 intergenerational caregivers of preterm infants admitted to the NICU of tertiary obstetrics and gynecology hospitals in Zhejiang and Jilin provinces from December 2023 to February 2024. Semi-structured interviews were conducted on the day of discharge of the preterm infants and six weeks after discharge. Colaizzi's seven-step analysis method was used to analyze the interview data. RESULTS: Based on the existence, relatedness, and growth (ERG) theory, the discharge preparation experiences and needs of neonatal intergenerational caregivers in the NICU were summarized into three themes: psychological condition, care capacity condition, and multi-party support needs. CONCLUSIONS: In the process of hospital discharge preparation, intergenerational caregivers of premature infants in NICU have multiple needs, including enhancing nursing ability and obtaining psychological and multi-party support. It is helpful to take effective interventions to improve their readiness for discharge. PRACTICE IMPLICATIONS: The nursing staff should develop personalized discharge health education plans and continuous nursing plans to improve the level of discharge preparation. PATIENT OR PUBLIC CONTRIBUTIONS: There were no patient or public contributions.

Advanced prodrug strategies in nucleoside analogues targeting the treatment of gastrointestinal malignancies.

Gastrointestinal malignancies are common digestive system tumor worldwide. Nucleoside analogues have been widely used as anticancer drugs for the treatment of a variety of conditions, including gastrointestinal malignancies. However, low permeability, enzymatic deamination, inefficiently phosphorylation, the emergence of chemoresistance and some other issues have limited its efficacy. The prodrug strategies have been widely applied in drug design to improve pharmacokinetic properties and address safety and drug-resistance issues. This review will provide an overview of the recent developments of prodrug strategies in nucleoside analogues for the treatment of gastrointestinal malignancies.

[A case-control study on risk factors of female breast cancer in Zhejiang province].

OBJECTIVE: To investigate the risk factors on female breast cancer in Zhejiang province. METHODS: A case-control study was conducted in 200 cases of female breast cancer with histopathological diagnosis and 200 matched controls from Zhejiang province. RESULTS: Univariate conditional logistic regression showed that family history of malignant tumor and breast cancer, housing decoration in last 10 years, mammary hyperplasia, adverse life events, bra with steel rings, sleeping with bra, high fat and pickle intake, poor sleep were positively related to breast cancer; whereas environmental friendly decoration materials, long decoration time interval, workplace condition, more lactation and parity, high fruits intake, sufficient sleep were negatively related to breast cancer. Multivariate conditional logistic regression analysis showed that the risk factors included family history of other tumors [odds ratio (OR)= 1.571,95% confidence interval(CI):1.029-2.396],mammary hyperplasia (OR=3.066,95%CI:1.834-5.126), job-related life events (OR=4.575,95%CI:1.690-12.390),the death of a loved one (OR=2.555,95%CI:1.475-4.424), wearing bra at night (OR=1.902,95%CI:1.177-3.072),high fat intake (OR=2.709,95%CI:1.546-4.749) and salted food (OR=2.460,95%CI:1.300-4.653). Factors as environmental friendly decoration materials (OR=0.517,95%CI:0.339-0.789),workplaces condition (OR=0.430,95%CI:0.243-0.762),more lactation (OR=0.109,95%CI:0.013-0.896),enough sleep (OR=0.424,95%CI:0.205-0.880) were protective factors. CONCLUSION: Hereditary,psychological factors,lifestyle,environment and diet related factors are significantly associated with risk of breast cancer.

The Investigation of Hepatitis B Vaccine Immune Responses in Occult Hepatitis B Virus-Infected Patients.

Objectives: There is no effective treatment for occult hepatitis B virus infection (OBI) patients, and immunotherapy may be one of the most promising options. We aim to investigate the underlying mechanism and therapeutic potential of hepatitis B vaccine immunotherapy for OBI patients. Methods: Outpatient OBI patients were screened and randomly divided into treatment (Group A) and control (Group B) groups. At weeks 0, 4, and 24, patients in Group A received a subcutaneous/intramuscular injection of hepatitis B vaccine (Engerix-B, 20 µg/time) according to the standard vaccination schedule; patients in Group B served as blank control. The patients were followed for 36 weeks, with clinical, biochemical, virological, immunological, and imaging data collected and analyzed at weeks 0, 12, 24, and 36, respectively, and the relation between the virology and immunology results was analyzed. Results: Of the 228 OBI patients, 28 were excluded, and 200 were enrolled for observation. In the end, 44 patients were included in Group A and 39 in Group B after excluding lost cases. At week 0 (baseline), some patients in two groups had liver disease symptoms, HBV-related liver function damage, and liver fibrosis. 86.36% (38/44) and 82.05% (32/39) patients were positive for serum hepatitis B surface antibodies (anti-HBs) in Group A and Group B, respectively, with the median (quartile) of 42.47 (16.85, 109.1) and 39.27 (16.06, 117.4) mIU/ml, respectively. Reduced peripheral blood CD4+T, CD8+T, and B lymphocytes were found in some patients in two groups. These results were not statistically different between Group A and Group B (P>0.05). At week 36, all patients were serum anti-HBs (+) in Group A, with a median (quartile) of 1000 (483.9, 1000) mIU/ml, which was significantly higher than that at week 0 (P<0.05) and that in Group B (P<0.05). Compared to week 0, the number of CD8+ T and B lymphocytes increased significantly and were significantly higher than Group B at the same point. Two patients in Group B were found to have hepatitis B virus reactivation from week 12 to week 36. Correlation Analysis: Anti-HBs in Group A patients were positively correlated with B lymphocytes (r=0.3431, 0.3087, and 0.3041, respectively) and positively correlated with CD8+ T lymphocytes (r=0.4954, 0.3054, and 0.3455, respectively) at weeks 12, 24, and 36. Conclusion: Virological reactivation is a risk for OBI patients. Serum hepatitis B surface antibodies were significantly increased after hepatitis B vaccine treatment, the same as the numbers of peripheral blood B and CD8+ T lymphocytes; changes in hepatitis B surface antibody levels were positively correlated with the changes in peripheral blood B and CD8+ T lymphocytes.

Noncontrast Computed Tomography-Based Radiomics Analysis in Discriminating Early Hematoma Expansion after Spontaneous Intracerebral Hemorrhage.

OBJECTIVE: To determine whether noncontrast computed tomography (NCCT) models based on multivariable, radiomics features, and machine learning (ML) algorithms could further improve the discrimination of early hematoma expansion (HE) in patients with spontaneous intracerebral hemorrhage (sICH). MATERIALS AND METHODS: We retrospectively reviewed 261 patients with sICH who underwent initial NCCT within 6 hours of ictus and follow-up CT within 24 hours after initial NCCT, between April 2011 and March 2019. The clinical characteristics, imaging signs and radiomics features extracted from the initial NCCT images were used to construct models to discriminate early HE. A clinical-radiologic model was constructed using a multivariate logistic regression (LR) analysis. Radiomics models, a radiomics-radiologic model, and a combined model were constructed in the training cohort (n = 182) and independently verified in the validation cohort (n = 79). Receiver operating characteristic analysis and the area under the curve (AUC) were used to evaluate the discriminative power. RESULTS: The AUC of the clinical-radiologic model for discriminating early HE was 0.766. The AUCs of the radiomics model for discriminating early HE built using the LR algorithm in the training and validation cohorts were 0.926 and 0.850, respectively. The AUCs of the radiomics-radiologic model in the training and validation cohorts were 0.946 and 0.867, respectively. The AUCs of the combined model in the training and validation cohorts were 0.960 and 0.867, respectively. CONCLUSION: NCCT models based on multivariable, radiomics features and ML algorithm could improve the discrimination of early HE. The combined model was the best recommended model to identify sICH patients at risk of early HE.

The complete chloroplast genome of Torilis scabra (Apiaceae).

Torilis scabra (Thunb.) DC. is widely distributed in China and Japan and has been introduced to North America. In this study, the complete chloroplast genome sequence of the T. scabra was obtained by de novo assembly using the NGS data. The chloroplast genome of T. scabra was 157,855 bp in length and divided into four distinct regions, such as large single-copy region (85,362 bp), small single-copy region (17,993 bp), and a pair of inverted repeat regions (27,250 bp). The genome annotation predicted a total of 127 genes, including 82 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis with reported chloroplast genomes showed that T. scabra has a close genetic relationship with Anthriscus cerefolium.

Women's knowledge of human papillomavirus (HPV) and their attitudes toward HPV vaccine: preparing for HPV vaccination in China.

To explore women's knowledge of human papillomavirus (HPV) and attitudes toward the HPV vaccine in Zhejiang, China, women attending the checkup clinics were invited to participate. A questionnaire-guided interview was conducted with a representative sample of 1490 women, and 1432 effective questionnaires were obtained. The authors found 39.1% of women in urban areas and 27.1 % in rural areas had heard of HPV, whereas 23.7% and 15.1%, respectively, had heard of the HPV vaccine. The mean score of HPV knowledge was 3.75 in urban areas and 3.18 in rural areas, with a significant difference (P = .016). Of the sample who had heard of the HPV vaccine, the supportive mean score was 2.59 and 2.11, with a significant difference (P = .003). Women with more HPV knowledge were more likely to support the HPV vaccination (r = 0.50 and r = 0.61). The authors conclude that inadequate knowledge and misconceptions about HPV are common. Attitudes toward HPV vaccine are unsatisfactory. Education campaigns targeting different populations are needed prior to the introduction of an HPV vaccine.
