Aim: To demonstrate the clinical efficacy of combination capsule endoscopy (CE) and multiple-detector computed tomography (MDCT) diagnostic imaging in the identification of gastrointestinal hemorrhages.
Methods: In the present study, 123 patients with gastrointestinal hemorrhages of obscure origin (GHOO) were examined with CE in combination with MDCT. The results were compared with findings of surgical pathology.
Results: Of the 123 patients, 57.72% (71/123) of the patients exhibited positive CE findings compared with 30.08% (37/123) on MDCT alone (P < 0.01). When used in combination, 65.85% (81/123) of patients scored positively. The detection rate due to the combination of diagnostic imaging was significantly higher than that of MDCT alone (P < 0.01), but was not significantly higher than that of CE alone (P > 0.05). Integrating the two diagnostic platforms improved the diagnosis of stromal tumors, hemangioma, Crohn's disease, vascular anomaly, Meckel's diverticulum, and ancylostomiasis. There was no significant difference in the positive detection rate between CE and MDCT when confirmed by surgical pathology.
Conclusion: The contribution of CE is critical in the diagnosis of GHOO, given the fact that there is a significant difference in the detection rate between CE and MDCT, but there is no significant difference in the rate between CE plus MDCT and CE alone.

Department of Medical Oncology, Cancer Hospital, Harbin Medical University, Harbin, Heilongjiang, P. R. China.
Background: The standard first-line treatment for human epidermal growth factor receptor 2 (HER2)-positive recurrent/metastatic breast cancer currently includes pertuzumab plus trastuzumab and docetaxel. This study aimed to evaluate the effectiveness of KN026, an anti-HER2 bispecific antibody, plus docetaxel in first-line treatment of HER2-positive recurrent/metastatic breast cancer.
Methods: This open-label, single-arm, phase II study enrolled patients with HER2-positive recurrent/metastatic breast cancer in 19 centers across China from December 30, 2019 to May 27, 2021.

Objectives: To compare the maternal hemodynamic profile at 12 + 0 to 15 + 6 weeks' gestation in women who subsequently developed pre-eclampsia (PE) and those who did not, and to assess the screening performance of maternal hemodynamic parameters for PE in combination with the Fetal Medicine Foundation (FMF) triple test, including maternal factors (MF), mean arterial pressure (MAP), uterine artery pulsatility index and placental growth factor.
Methods: This was a prospective case-control study involving Chinese women with a singleton pregnancy who underwent preterm PE screening at 11 + 0 to 13 + 6 weeks' gestation using the FMF triple test, between February 2020 and February 2023. Women identified as being at high risk (≥ 1:100) for preterm PE by the FMF triple test were matched 1:1 with women identified as low risk (< 1:100) for maternal age ± 3 years, maternal weight ± 5 kg and date of screening ± 14 days.
Informed choices for some, but not for others: An exploration of Australian midlife women's participation in mammography screening by social class.
Womens Health (Lond)
January 2025
Research Centre for Public Health, Equity and Human Flourishing, Torrens University Australia, Adelaide, SA, Australia.
Background: Population-level mammography screening for early detection of breast cancer is a secondary prevention measure well-embedded in developed countries, and the implications for women's health are widely researched. From a public health perspective, efforts have focused on why mammography screening rates remain below the 70% screening rate required for effective population-level screening. From a sociological perspective, debates centre on whether 'informed choice' regarding screening exists for all women and the overemphasis on screening benefits, at the cost of not highlighting the potential harms.
