High-throughput immune repertoire (IR) sequencing provides direct insight into the diversity of B cell receptor (BCR) and T cell receptor (TCR), with great potential to revolutionize the diagnosis, monitoring, and prevention of immune system-related disorders. In this study, multiplex PCR was applied to amplify the complementarity-determining regions of BCR and TCR, followed by comprehensive analysis by high-throughput sequencing. We compare the TCR (BCR) of bone marrow fluid (BMF) and peripheral blood (PB) samples from 17 patients in the Epstein-Barr and immunodeficiency groups, respectively. ⋯ However, the distributions of the monoclonal genes are significantly different in these 2 samples of most patients. This suggests that the BMFs can be replaced by the PB samples in diversity detection of IR to monitor the immune status of the body, while the detection of the BMFs is unreplaceable when the monoclonal change occurs. We used high-throughput sequencing to assess the TCR and BCR of the patients and provide a basis for the clinical analysis of PB and bone marrow samples and selection of disease diagnosis and monitoring methods.

Effect of targeted temperature management on systemic inflammatory responses after out-of-hospital cardiac arrest: A prospective cohort study.
Interleukin (IL)-6 is a major inflammatory cytokine that predicts mortality after out-of-hospital cardiac arrest (OHCA). Targeted temperature management (TTM) is associated with improved all-cause mortality in patients with OHCA. However, the effect of TTM on IL-6 production remains unclear. This study investigated whether TTM has additional anti-inflammatory effects after OHCA. ⋯ TTM improves both the mortality rate and neurologic outcomes in patients resuscitated from OHCA, possibly by reducing IL-6-induced proinflammatory responses.

Incidence of associated anomalies in children with anorectal malformation: A 1-year prospective observational study in a low-income setting.
Anorectal malformations (ARMs) consist of a range of anomalies that are often associated with other anomalies The purpose of the study is to assess the incidence of associated congenital anomalies that are seen in patients with ARMs. An observational prospective study was conducted on 162 cases with ARM from February 2019 to January 2020, and data were collected on patient demographics, type of ARM, and associated anomalies using a prestructured questionnaire and analysis done using SPSS (IBM), version 23, software. Relevant statistical analysis was done, and the results are presented in tables and charts. ⋯ More than half of the children have other associated abnormalities. We found urogenital anomalies to be the most common associated congenital defects. A lower incidence of cardiac and spinal cord anomalies was noted suggesting a need for active workup to be in line with the latest standards of care.

Observational Study
An evaluation of serum blood parameters and amyloid-A levels in women with hyperemesis gravidarum; A prospective observational study.
This study aimed to investigate whether serum amyloid A (AA) level can be used as a biomarker in women with hyperemesis gravidarum (HEG). This prospective observational study was conducted at the Antalya Training and Research Hospital Gynecology and Obstetrics Clinic, Türkiye, between July and December 2023. Forty women diagnosed with HEG and 40 healthy women were included. ⋯ The positive predictive value of serum AA was 81.1% and the negative predictive value was 80.4%. The study results showed that serum AA can be used as a diagnostic biomarker in HEG. Prospective studies involving more participants are now required to confirm our results.

Primary ovarian carcinoid tumors are rare neoplasms, first reported in 1939, with approximately 30 cases reported thus far. It is categorized into insular, trabecular, strumal, and mucinous types. Mucinous forms are extremely rare, comprising < 2% of all primary ovarian carcinoid tumors. ⋯ Approximately 40% of primary ovarian carcinoid tumors with insular morphology present in pure form, and mucinous forms are extremely rare. At present, the main diagnostic methods in cases of primary ovarian mucinous carcinoid tumor include macroscopic examination, histopathology and imaging examination. The main treatment modalities for primary ovarian mucinous carcinoid tumor are surgery. postoperative chemotherapy remains controversial.
