Prediction of preoperative peritoneal cancer index for pseudomyxoma peritonei by multiple linear regression analysis.

Background: The aim of the present study was to establish a predictive model to predict the peritoneal cancer index (PCI) preoperatively in patients with pseudomyxoma peritonei (PMP).

Methods: A total of 372 PMP patients were consecutively included from a prospective follow-up database between 1 June 2013 and 1 June 2023. Nine potential variables, namely, gender, age, Barthel Index (BAI), hemoglobin (Hb), albumin (Alb), D-dimer, carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA 125), and CA 19-9, were estimated using multiple linear regression (MLR) analysis with a stepwise selection procedure.

Howell-Jolly Body-Like Neutrophil Inclusions Following Hematopoietic Stem Cell Transplantation: A Case Report.

BACKGROUND In several studies, the presence of Howell-Jolly body-like inclusions within neutrophils has been observed in cases of HIV infection, SARS-CoV-2 infection, post-transplant immunosuppression, and during chemotherapy or antiviral therapy. The phenomenon of neutrophils exhibiting Howell-Jolly body-like inclusions on peripheral blood smears can be attributable to viral infections or the pharmacological effects of medications. CASE REPORT A 14-year-old male patient who had received a diagnosis of lymphoblastic leukemia a year ago underwent hematopoietic stem cell transplantation and was readmitted due to a recurrence of gastrointestinal graft-versus-host disease (GVHD).

A Rare Case of NK Large Granular Lymphocytic Proliferative Disorder.

Background: Chronic NK-cell lymphoproliferative disease (CLPD-NK) is a very rare lymphoproliferative disorder in which patients often have an elevated lymphocyte population without clinical symptoms.

Methods: In this particular case, a middle-aged woman presented with a consistent elevation in her lymphocyte proportion over a span of four consecutive years during physical examinations, without manifesting any other notable clinical symptoms. The underlying cause of this phenomenon was ultimately identified through a comprehensive evaluation that encompassed peripheral blood cell morphology analysis, lymphocyte subset profiling, and peripheral blood immunophenotyping.

Combined effect of triglyceride glucose-body mass index and hypertension on new-onset stroke: evidence from the China health and retirement longitudinal study.

Objective: The aim of this study is to investigate the combined impact of the triglyceride glucose-body mass index (TyG-BMI) and hypertension on the risk of stroke among the middle-aged and older adult population in China.

Methods: This study included 6,922 participants aged 45 and above from the China Health and Retirement Longitudinal Study, utilizing a multivariate proportional hazards regression model to explore the relationship between TyG-BMI, hypertension, and the incidence of new-onset stroke events, as well as conducting Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI) analyses to evaluate the predictive utility of TyG-BMI.

Results: During a 7-year follow-up period, a total of 401 stroke events were recorded.

SARS-CoV-2 not Detected in the Nasopharyngeal Sample but in Bronchoalveolar Lavage Fluid.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection typically relies on reverse transcription-polymerase chain reaction (RT-PCR) technology. However, there is a certain rate of missed detection of SARS-CoV-2 in nasopharyngeal samples, particularly among immunosuppressed individuals.

Methods: In this case, SARS-CoV-2 was detected in nasopharyngeal swabs and bronchoalveolar lavage fluid (BALF) using RT-PCR.

A compact microfluidic platform for rapid multiplex detection of respiratory viruses via centrifugal polar-absorbance spectroscopy.

Nucleic acid detection technology has become a crucial tool in cutting-edge research within the life sciences and clinical diagnosis domains. Its significance is particularly highlighted during the respiratory virus pandemic, where nucleic acid testing plays a pivotal role in accurately detecting the virus. Isothermal amplification technologies have been developed and offer advantages such as rapidity, mild reaction conditions and excellent stability.

Advances in reprogramming of energy metabolism in tumor T cells.

Cancer is a leading cause of human death worldwide, and the modulation of the metabolic properties of T cells employed in cancer immunotherapy holds great promise for combating cancer. As a crucial factor, energy metabolism influences the activation, proliferation, and function of T cells, and thus metabolic reprogramming of T cells is a unique research perspective in cancer immunology. Special conditions within the tumor microenvironment and high-energy demands lead to alterations in the energy metabolism of T cells.

Hematuria after nocturnal exercise of a man: A case report.

Background: A man experienced multiple episodes of macroscopic hematuria following nocturnal exercise. Urinary stones and tumors were considered the two most likely causes. The patient had two hobbies: Consuming health care products in large quantities and engaging in late-night running.

Artificial intelligence of digital morphology analyzers improves the efficiency of manual leukocyte differentiation of peripheral blood.

Background And Objective: Morphological identification of peripheral leukocytes is a complex and time-consuming task, having especially high requirements for personnel expertise. This study is to investigate the role of artificial intelligence (AI) in assisting the manual leukocyte differentiation of peripheral blood.

Methods: A total of 102 blood samples that triggered the review rules of hematology analyzers were enrolled.

Preoperative assessment of complicated appendicitis through stress reaction and clinical manifestations.
