Article Abstract
Background: Thrombocytopenia is commonly observed in patients with sepsis and is an independent risk factor for poor prognosis. However, the changes of platelet count caused by different pathogens can vary significantly. Our study aims to evaluate the quantitative changes in platelet count in response to various pathogens.
Material And Methods: We retrospectively analysed data of 3044 patients with sepsis from Medical Information Mart for Intensive Care (MIMIC, 2008-2019) database and prospectively collected data of 364 patients with sepsis from our local cohort of the Shandong Bloodstream Infection and Sepsis Collaboration Study (SBISC, 2020-2022). Propensity score matching (PSM) was employed to control for baseline differences in variables, except for the causative pathogen.
Results: Multivariate logistic analyses of both original and PSM populations identified , , , and species posing a higher risk for thrombocytopenia compared to others. Restricted cubic spline (RCS) curves showed L- or U-shaped associations between platelet count and 28-mortality with various cut-off values among different pathogens: ranging from 96 × 10/L in species - 190 × 10/L in species.
Conclusion: Our present findings indicate a pathogen-specific effect on platelet count, highlighting the importance of monitoring thrombocytopenia in patients infected with above microorganisms. Clinicians need to consider pathogen-specific thresholds when intervene on platelet count.

This study aimed to synthesize and evaluate the anticancer activity of novel chalcone derivative against colon cancer by in vitro cytotoxicity against HCT-116 (Research Resource Identifiers:CVCL_D4JB) cell line and in vivo using EAC (Research Resource Identifiers: CVCL_1306) and DLA (Research Resource Identifiers: CVCL_VR37) cells inoculated Swiss albino mice. The present study aimed to synthesize the new chalcone derivatives and conduct its anti-colon cancer activity both in vitro and in vivo. The designed compounds were subjected to in silico studies like binding pocket analysis, molecular docking, and ADME studies.

Background: Thrombotic thrombocytopenic purpura (TTP) is a life-threatening hematologic emergency caused by ADAMTS13 deficiency, leading to microvascular thrombosis, haemolytic anaemia, thrombocytopenia, and end-organ damage. Neurological symptoms occur in up to 90% of cases and are frequently misdiagnosed as stroke. Prompt recognition and treatment reduce the mortality rate from over 90% to 10-20%.

Unlabelled: B-cell lymphomas are highly aggressive forms of lymphoma that commonly present with lymphadenopathy, systemic "B" symptoms, or organ involvement making them easy to recognize; however, a small percentage of B-cell lymphomas can present without any typical symptoms or evidence of lymphadenopathy, resulting in delayed recognition and management. Isolated thrombocytopenia without anaemia or leukopenia is an unusual presentation of B cell lymphomas and may be misdiagnosed as immune thrombocytopenia (ITP). Given the rarity of this presentation, we wish to report a case of a 76-year-old female who presented with palpitations, shortness of breath, and recurrent chest infections.

Objective: Vitamin C has been linked to alterations in platelet count and aggregation behavior. Given recent findings suggesting an association between vitamin C and adverse outcomes in patients with septic shock, we aimed to investigate whether vitamin C influences mortality in septic patients through its impact on platelets.
Design: Post hoc analysis of the Lessening Organ Dysfunction With Vitamin C (LOVIT) randomized trial (clinicaltrials.

Objective: This study aimed to assess the predictive capacity of placenta growth factor (PlGF) and pregnancy-associated plasma protein-A (PAPP-A) levels in the serum of pregnant women during early pregnancy (11-13 weeks) for fetal growth restriction (FGR).
Patients And Methods: A retrospective cohort study was conducted involving 1602 pregnant women who gave birth at The Second Nanning People's Hospital between March 2018 and September 2019. Serum concentrations of PlGF and PAPP-A were measured during early pregnancy for all participants.
