Observational Study
Analysis of factors influencing pregnancy and its outcomes in women undergoing in vitro fertilization-embryo transfer/frozen embryo transfer cycles: A retrospective study.
The relationship between clinical outcomes and various factors influencing pregnancy was analyzed to provide reference data for patients and clinicians when selecting embryo transfer protocols. This was a retrospective study of 1309 transfer cycles between June 1, 2018, and May 1, 2023, in the Reproductive Medicine Center. Univariate analysis was performed on various factors that may have affected pregnancy outcomes, and further regression analysis was performed on those factors found by univariate analysis to correlate positively with clinical pregnancy outcomes. ⋯ The results showed that the stage of embryonic development significantly affected pregnancy outcomes after transplantation (P < .01, 95% confidence interval: 2.554 [1.958-3.332]). There was no significant difference in the pregnancy rate between 1 high-quality blastocyst transfer and 2 cleavage-stage embryos or blastocyst transfer (64.22% vs 70.11%, P = .439); however, the rate of multiple pregnancies after 1 high-quality blastocyst transfer was close to the rate of natural conception. These data show that the transfer of single high-quality blastocysts can significantly reduce the multiple pregnancy rate while ensuring an ideal pregnancy rate, which can be used as a reference for planning the first transplantation in patients with good prognoses.

Foreign body aspiration (FBA) is a serious preventable pediatric health problem and one of the main causes of accidental death in children. Although unusual in adults, it is often overlooked as a cause of airway obstruction with serious consequences. This study assessed awareness and previous FBA experiences in the Asir community, Kingdom of Saudi Arabia. ⋯ Older age, being a health practitioner, and perceiving FBA as a serious incident were significantly associated with good knowledge (P < .001). The findings of this study indicate an urgent need to raise community awareness of FBA. To reduce FBA morbidity and mortality, health education efforts in community and healthcare settings are required to educate people about the seriousness and importance of early diagnosis and management of the condition.

Renal clear cell carcinoma (RCC) is a type of malignant tumor, which, in addition to surgical resection, radiotherapy, and chemotherapy, has been widely treated through immunotherapy recently. However, the influence of the tumor microenvironment and the infiltrating immune cells within it on immunotherapy remains unclear. It is imperative to study the interactions between various immune cells of RCC. ⋯ HSPA1A was correlated with DNAJB1 in microglia. Compared with Paracancer tissues, microglia increased while CD1C+ B dendritic cells decreased in pathological stages I and I-II in cancerous tissues. An altered tumor microenvironment caused by increases in microglia in RCC in the early stage resulted in an inability of CD1C+ B dendritic cells to infiltrate, resulting in CD8+ T cells being unable to receive the antigens presented by them, and in turn being depleted in large quantities.

Respiratory microbiome and clinical course of carbapenem-resistant Acinetobacter baumannii pneumonia in critically Ill patients.
Carbapenem-resistant Acinetobacter baumannii (CRAB) pneumonia has been a serious problem in the intensive care unit (ICU). However, defined characteristics of respiratory microbiome in CRAB pneumonia are lacking nowadays. This study aimed to analyze respiratory microbiome of CRAB pneumonia compared to non-CRAB pneumonia and reveal the clinical significance of respiratory microbiome data in these patients. ⋯ Among CRAB pneumonia cases, 3 respiratory specimens were culture-negative, but positive by microbiome analysis. Lower respiratory microbiome in CRAB pneumonia had distinct characteristics and early loss of diversity compared to non-CRAB pneumonia, which might be related to poor clinical course. Moreover, CRAB acquisition and colonization would be predicted by preemptive microbiome analysis, which will contribute to effective infection control in the ICU.

This study aimed to investigate the association between high-sensitivity C-reactive protein (hs-CRP) levels, as a surrogate marker of systemic inflammation, and renal function among Korean adults grouped by age, sex, and body mass index. This study analyzed data obtained from the Korea National Health and Nutrition Examination Survey 2015 to 2018, a cross-sectional and nationally representative survey conducted by the Korean Centers for Disease Control and Prevention. Of the 22,451 subjects included in this study, 19,607 (87.3%) and 2844 (12.7%) had normal kidney function and incident chronic kidney disease, respectively. ⋯ Moreover, reduced renal function was more observed in subjects aged ≥ 65 years and those with a body mass index < 25 kg/m2 (OR, 1.502; 95% CI, 1.087-2.075). This study showed that a high hs-CRP level likely contributes to the increased prevalence of reduced renal function. This association may aid the identification of individuals at high risk for reduced renal function, especially elderly women, in clinical or public health practice.
