This systematic review and meta-analysis aimed to evaluate the impact of prospective payment systems (PPSs) on cholecystectomy.A comprehensive literature review was conducted, examining studies published until December 2023. The review process focused on identifying research across major databases that reported critical outcomes such as length of stay (LOS), mortality, complications, admissions, readmissions, and costs following PPS for cholecystectomy. The studies were specifically selected for their relevance to the impact of PPS or the transition from fee-for-service (FFS) to PPS. The study analyzed six papers, with three eligible for meta-analysis, to assess the impact of the shift from FFS to PPS in laparoscopic and open cholecystectomy procedures. Our findings indicated no significant changes in LOS and mortality rates following the transition from FFS to PPS. Complication rates varied and were influenced by the diagnosis-related group categorization and surgeon cost profiles under episode-based payment. There was a slight increase in admissions and readmissions, and mixed effects on hospital costs and financial margins, suggesting varied responses to PPS for cholecystectomy procedures. The impact of PPS on cholecystectomy is nuanced and varies across different aspects of healthcare delivery.Our findings indicate a need for adaptable, patient-centered PPS models that balance economic efficiency with high-quality patient care. The study emphasizes the importance of considering specific surgical procedures and patient demographics in healthcare payment reforms.

In China, the current standard for cosmetic adverse reactions related skin disease (GB/T 17149.1-1997) was jointly issued by the Ministry of Health and the State Bureau of Technical Supervision in 1997, cosmetic-allergic adverse reactions include allergic contact dermatitis and photo-allergic contact dermatitis according to this standard. The increasing use and changes in cosmetic ingredients or formula lead to a significant increase for the incidence of adverse reactions as the cosmetics industry is developing rapidly in the last 20 years. In the meantime, the clinical manifestations have become more diverse. In recent years, there have been many reports on the special manifestations for cosmetic allergy and allergen test, which provide a reference for the subsequent improvement of the diagnosis and prevention.

Objectives: The aim of these Clinical Practice Guidelines is to provide evidence-based recommendations to assist healthcare providers in the screening, diagnosis and management of patients with postmenopausal osteoporosis (OP). Methods: A list of key clinical questions on the assessment, diagnosis and treatment of OP was formulated. A literature search using the PubMed, Medline, Cochrane Databases of Systematic Reviews, and OVID electronic databases identified all relevant articles on OP based on the key clinical questions, from 2014 onwards, to update from the 2015 edition. The articles were graded using the SIGN50 format. For each statement, studies with the highest level of evidence were used to frame the recommendation. Results: This article summarizes the diagnostic and treatment pathways for postmenopausal OP. Risk stratification of patients with OP encompasses clinical risk factors, bone mineral density measurements and FRAX risk estimates. Non-pharmacological measures including adequate calcium and vitamin D, regular exercise and falls prevention are recommended. Pharmacological measures depend on patients’ fracture risk status. Very high-risk individuals are recommended for treatment with an anabolic agent, if available, followed by an anti-resorptive agent. Alternatively, parenteral anti-resorptive agents can be used. High-risk individuals should be treated with anti-resorptive agents. In low-risk individuals, menopausal hormone replacement or selective estrogen receptor modulators can be used, if indicated. Patients should be assessed regularly to monitor treatment response and treatment adjusted, as appropriate. Conclusions The pathways for the management of postmenopausal OP in Malaysia have been updated. Incorporation of fracture risk stratification can guide appropriate treatment.

Objective To investigate the effects of multimedia information technologies on precision radiotherapy of head and neck malignant tumors (HNT). Methods A total of 96 patients with HNT recruited from 2016 to 2019 were randomly assignedto group A and group B with the same planning methodand therapists/technicians. Conventional and multimedia information technologies were respectively used in group A and group B for medical science popularization, individualized education, and doctor-patient communication before radiotherapy planning and positioning. Medical compliance, radiotherapy responses, setup errors, and machine occupancy time were investigated. Results Medical compliance was significantly higher (P < 0.05) in group A (96.5%) than in group B (73.8%). Skin acute radiation reaction was significantly lower (P < 0.05) in group A than in group B. Three-dimensional absolute setup errors were 0.69 ± 0.29 mm, 0.97 ± 0.69 mm, and 0.79 ± 0.47 mm in group A, which were significantly lower than 1.39 ± 0.81 mm, 1.87 ± 1.19 mm, and 2.50 ± 0.99 mm in group B(P < 0.05). Traditional three-dimensional setup errors were 0.73 ± 0.39 mm, 0.51 ± 0.69 mm, and 0.74 ± 0.17 mm in group A, which were significantly lower than 1.32 ± 0.76 mm, 1.89 ± 1.21 mm, and 1.37 ± 0.57 mm in group B (P < 0.05). Planning time was 145.15 ± 28.45 sin group A, which was significantly lower than 240.38 ± 50.45 sin group B (P < 0.05). Positioning time was 115.15 ± 18.45 s in group A, which was significantly lower than 173.38 ± 24.45 sin group B (P < 0.05). Conclusion The application of multimedia information technologies inmedical science popularization, individualized education, and doctor-patient communication forpatients who received precision radiotherapy for HNT can significantly increase patient compliance, alleviate acute radiation reactions, reduce setup errors, and shorten the machine occupancy time of planning and positioning.

The patient was found to develop a migrating mass in the lower abdomen without any known cause in 2000, and the cause had not been identified following multiple diagnoses since then. The mass was found to migrate to the left anterior axillary regions on August 11, 2020. Then, three segments of incomplete white worms were resected through minimally invasive surgery, and metagenomic sequencing revealed sparganosis mansoni. After surgical resection of complete worms was performed on October 21, 2021, the case was cured and discharged from the hospital. Follow-up revealed satisfactory outcomes and no new mass was found throughout the body.

Purpose: The updated American Society of Clinical Oncology/College of American Pathologists guideline for estrogen receptor (ER) testing recommends that breast cancer with ER expression in 1–10% of tumor cells should be reported as ER-low positive (ERlow), although limited data are available on the overall benefits of endocrine therapy. We investigated the clinicopathological characteristics and clinical outcomes of ERlow breast cancer and to compare them with those of ER-negative (ERneg) and ER-high (> 10% of tumor cells, ERhigh) breast cancers. Methods: Consecutive patients with invasive breast cancer who underwent curative surgery between November 2007 and December 2014 were included. Clinicopathological characteristics and disease-free survival (DFS) of ERlow tumors were compared with those of ERneg and ERhigh tumors. Results: Of the 2,309 cases included, 46 (2%), 643 (27.8%), and 1,620 (70.2%) were ERlow , ERneg , and ERhigh , respectively. ERlow tumors were associated with no special type of histology (p = 0.011), advanced pT (p = 0.017), pN (p = 0.009) and anatomic stages (p < 0.001), high grade (p < 0.001), negative/low progesterone receptor (PR) status (p < 0.001), human epidermal growth factor receptor 2 positivity (p < 0.001), high Ki-67 (p < 0.001), and recurrence (p = 0.006) compared to ERhigh tumors. DFS was significantly dependent on ER status, and ERlowtumors showed poorer DFS than ERhigh tumors (p = 0.001), however, there was no significant survival difference between ERlow and ERneg tumors. Furthermore, DFS in ERhigh patients was affected by hormone therapy (p < 0.001), while it was not affected in ERlow patients. Conclusion Patients with ERlow breast cancer have clinicopathological characteristics that differ from those with ERhigh tumors. Although this study was limited by the small sample size of the ERlow group, no benefit from hormone therapy was observed in the ERlow group compared with the ERhigh group.

Objective:To observe the stability of severe acute respiratory syrdrome coronavirus （SARS-CoV-2） in cell cultures at different temperatures so as to provide basic data and scientific basis for the research and control of COVID-19 epidemic. Methods:The Vero E6 cells inoculated with SARS-CoV-2. According to TCID₅₀， SARS-CoV-2 with different dilution （10^-1， 10^-3， 10^-5， 10^-6）were stored at 37 °C， 22.5 °C， and 4 °C for one to seven days， and then infectious titer was determined by micro cytopathogenic effect assay， observing cytopathic effect （CPE）， and real-time fluorescence quantitative testing. Results:SARS-CoV-2 was stable under 4 °C. The infectivity of high concentration （10^-1 dilution） under 22.5 °C for seven days gradually decreased， while lower concentration completely lost infectivity after one day. The virus lost infectivity when stored at 37 °C for more than one day. Conclusion:SARS-CoV-2 is highly stable at 4 °C， sensitive to heat， and related to virus concentration.
