RESUMEN
Objective: This study aimed to analyze tumor necrosis factor alpha (TNF-α) level in the uterine fluid of patients with polycystic ovary syndrome (PCOS) and its correlation with the clinical parameters of PCOS. Methods: A total of 162 patients treated in the Reproductive Medicine Center of the General Hospital of Ningxia Medical University between December 2019 and November 2021 were enrolled as research subjects, including 80 patients with PCOS and 82 patients with other gynecological disease, who were used as the controls. The patients' general data, along with blood glucose, blood lipid, insulin, and sex hormone levels and other data, were collected. The TNF-α levels in the patients' serum and uterine fluid were detected using enzyme-linked immunosorbent assay. Results: Compared with the patients in the control group, the body mass index (BMI), anti-Müllerian hormone, luteinizing hormone, testosterone (T), fasting insulin (FINS), homeostasis model assessment insulin resistance (HOMA-IR), triglyceride (TG), and low-density lipoprotein (LDL) of patients with PCOS were higher, and high-density lipoprotein was lower (P < 0.05). The TNF-α levels in the serum and uterine fluid of patients with PCOS were higher than those in the control group (P < 0.01), and the TNF-α levels in the uterine fluid of these patients was significantly correlated with BMI, T, FINS, HOMA-IR, serum TNF-α, TG, and LDL (P < 0.05). Conclusion: There is local inflammation in the uterine cavity of patients with PCOS, and the detection of cytokines in uterine secretions may be a simple and feasible method of understanding the uterine microenvironment of patients with PCOS.
RESUMEN
TP53 disruption is considered to be the most important prognostic factor in chronic lymphocytic leukemia (CLL), but not all patients with TP53 disruption have similar dismal outcomes. We evaluated the prognostic value of TP53 disruption in CLL patients without treatment indications. Data of 305 CLL patients were analyzed. 41 of them (13%) had TP53 disruption. Patients with lower percentage of cells with del(17p) had significantly better survival. Patients with mutated IGHV, ß2-microglobulin ≤3.5 mg/L, wild-type TP53, age ≤65 years or without complex karyotype (CK) had relatively favorable outcomes in the del(17p) group. Furthermore, patients with del(17p) as a minor clone showed survival advantage compared with those with del(17p) as a major clone. These data suggest that the percentage of cells with del(17p), the size of the del(17p) subclone, CLL International Prognostic Index, and CK should be considered to build refined prognostication models for patients with TP53 disruption.

Fatal child maltreatment is a compelling problem in the United States. National estimates of fatal child maltreatment, based largely on child welfare data, have fluctuated around 1,500 deaths annually for the past ten years. However, the limitations of child welfare and other mortality data to accurately enumerate fatal child maltreatment are well documented. As a result of these limitations, the true magnitude of fatal child maltreatment remains unknown. Public health surveillance has been proposed as a mechanism to improve estimation of fatal child maltreatment, as well as to collect and analyze relevant risk factor data for the ultimate goal of developing prevention strategies. This paper describes public health surveillance efforts undertaken to improve estimation of fatal child maltreatment, and presents the unique challenges of identifying fatal child neglect. The strengths and limitations of existing sources of child maltreatment fatality data are reviewed and broad recommendations for strategies to advance public health surveillance of fatal child maltreatment are presented.

The aim of this study was to explore the effect of DAPT (N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycinet-butyl ester) on proliferation in vitro of human multiple myeloma cell line RPMI8226 and its underlying mechanism. The proliferation of RPMI8226 cells was detected by CCK-8 method; flow cytometry was employed to assay the cell apoptosis rate;the expressions of Notch1 and Hes1 proteins were detected by Western blot. The results indicated that the proliferation of human RPMI8226 cells significantly decreased after treatment with DAPT 0.5 - 5.0 µmol/L for 24 - 72 h (P < 0.05) in a concentration- and time-dependent manner. DAPT significantly induced apoptosis of RPMI8226 cells (P < 0.05). The expressions of Notch1 and Hes1 proteins were gradually downregulated with the increase of DAPT concentration. It is concluded that the DAPT can inhibit the proliferation of RPMI8226 cells, which may be related with the down-regulation of the protein expression of Notchl and Hes1.

OBJECTIVE: This article reviewed the different surveillance systems used to monitor the extent of reported child maltreatment in North America. METHODS: Key measurement and definitional differences between the surveillance systems are detailed and their potential impact on the measurement of the rate of victimization. The infrastructure requirements, quality of information, timely access to data and the usefulness for child welfare policy are compared and contrasted and a summary table of the type of information by each system is presented. RESULTS: Two studies collect data regarding the extent and nature of child maltreatment using survey methodology reported to professionals: the United States National Incidence Study of Child Abuse and Neglect (NIS) and the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS), and the United States National Child Abuse and Neglect Data System (NCANDS) uses administrative data methods to collect annual case-level and state data. PRACTICE IMPLICATIONS: The purpose of this comparison is to assist researchers and policy analysts with interpreting data from these studies as well as to help officials from other countries in developing surveillance systems that are appropriately adapted to their needs.

Most child subjects of maltreatment reports to child protective services (CPS) are involved just once, whereas other children experience repeated investigations and victimizations. This study examines individual, maltreatment, and service-related factors associated with maltreatment rereporting and substantiated rereporting in a multistate context. Case-level National Child Abuse and Neglect Data System data (505,621 children) were analyzed. Within 24 months, 22% of children were rereported, and 7% were rereported with substantiation. Younger and White and mixed race children, those with disabilities, and those whose caregivers abused alcohol were more likely to be rereported and rereported and substantiated. Service provision, including foster care placement, was associated with increased likelihood of subsequent events. When CPS agency performance is assessed using measures of reentry, separate measures may be necessary for children who receive services, so that improvements in safety can be appropriately recognized. Reentry into CPS is a complex interaction of risks to children and systemic factors tied to the intervention they receive.
