Association between dietary niacin intake and chronic obstructive pulmonary disease among American middle-aged and older individuals: A cross-section study.

Background: The attention towards the relationship between chronic obstructive pulmonary disease (COPD) and dietary intake is escalating. However, the effects of dietary niacin on COPD in middle and older individuals remains unclear. This study aimed to illuminate the connection between dietary niacin intake and COPD.

Combining PCT with CRP is better than separate testing for patients with bacteriuria in the intensive care unit: a retrospective study.

Background: Previous studies on PCT for urinary tract infections (UTI) have focused primarily on minors. This study investigated the predictive value of the neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP) level and procalcitonin (PCT) level in adult patients with bacteriuria in IUC.

Methods: This case‒control study included 85 patients with bacteriuria (PB) in the ICU from March 2021 to Jan 2024 based on positive urine culture results and a control group (n = 136) from Jan 2024 to March 2024.

A Novel LDLC Equation is Superior to the NIH LDLC Equation and the Friedewald Equation.

Background: LDLC equations have varying levels of underestimation for the calculated LDLC. Therefore, underestimating LDLC should be avoided as much as possible. We need to establish LDLC equations that underestimate LDLC as little as possible.

"One-gate" design should be used for the study of the diagnostic efficacy of biological markers.

1. The first draft of this article proposes "Please authors answer a question: was there only 43 patients with diagnosed gastric cancer from April 2018 to July 2018?" Is it to know whether the researchers chose 43 patients because of fewer cases or intentionally fewer? The reviewer's "response reviewers" admitted "it's better to add a benign disease group" and "chose 43 patients with diagnosed gastric cancer randomly for our validation," which confirmed my opinion "have design flaws both in enroll subjects and the number of cases". So after getting the reply from the original author, I deleted the above sentence.

Limiting the testing of urea: Urea along with every plasma creatinine test?

Background: We found that it is not necessary to simultaneously detect both creatinine (CREA) and urea until the concentration of CREA is lower than the certain level. To reduce urea testing, we suggest measuring urea only when CREA or estimated glomerular filtration rate (eGFR) exceeds a predetermined limit.

Materials And Methods: CREA and urea data were analyzed consisting of almost all of people age above 65 years old check-up (n=95441) in Shuyang countryside, and inpatients (n=101631), outpatients (n=18474) and Routine Health Check-up (n=20509) in Shuyang People's Hospital.

Reference Intervals of Alpha-Fetoprotein and Carcinoembryonic Antigen in the Apparently Healthy Population.

BACKGROUND The aim of this study was to calculate 95% reference intervals and double-sided limits of serum alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) according to the CLSI EP28-A3 guideline. MATERIAL AND METHODS Serum AFP and CEA values were measured in samples from 26 000 healthy subjects in the Shuyang area receiving general health checkups. The 95% reference intervals and upper limits were calculated by using MedCalc.

Establishing Reference Intervals of Aspartate Aminotransferase-to-Platelet Ratio Index for Apparently Healthy Elderly.

Background: Aspartate aminotransferase (AST) to platelet ratio index (APRI) serves as a parameter in evaluating liver fibrosis in current clinical practice. However, reference standard (reference intervals, RIs) or baseline levels of APRI have not been previously reported. The purpose of this paper is to establish the reference intervals of APRI in apparently healthy elderly people from the region of Shuyang, China.

T-SPOT.TB in Detection of Active Tuberculosis During Pregnancy: A Retrospective Study in China.

Background: Interferon-gamma release assays have not been validated in active TB among pregnant women. Therefore, the objective of this retrospective study was to estimate the diagnostic value of T-SPOT.TB in active TB among pregnant women.

Reference intervals for total bilirubin, ALT, AST and creatinine in healthy Chinese elderly.

Background: The aim of this study was to establish the reference intervals (RIs) of total bilirubin (TBIL), alanine aminotransferase (ALT), aspartate transaminase (AST), and creatinine (CREA) for apparently healthy elderly (Han ethnicity) in Shuyang, China.

Material And Methods: A total of 54 912 blood specimens from elderly residents age 65-104 years were collected by standard procedures in Shuyang county of Jiangsu province. TBIL, ALT, AST, and CREA for each participant were determined by automatic biochemical analyzer.

Associations of adiponectin gene polymorphisms with polycystic ovary syndrome: a meta-analysis.

Adiponectin gene polymorphisms have been implicated in polycystic ovary syndrome (PCOS) development. However, results from previous studies were inconsistent and inconclusive. To shed some light on the relationship of two adiponectin gene polymorphisms, T45G and G276T, with PCOS, we conducted the current meta-analysis.

Proteome analysis of biomarkers in the cerebrospinal fluid of neuromyelitis optica patients.

Purpose: To better understand the pathophysiological mechanisms underlying neuromyelitis optica (NMO), we developed a proteomics platform for biomarker discovery in the cerebrospinal fluid (CSF) of patients with NMO.

Methods: Two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) were used to compare the CSF proteome of NMO patients with that of controls. A subsequent ELISA and western blot analysis were performed to verify the results of the proteomic analysis.

Proteome analysis of haptoglobin in cerebrospinal fluid of neuromyelitis optica.

Neuromyelitis optica (NMO) is an inflammatory demyelinating disease with generally poor prognosis that selectively targets optic nerves and spinal cord. Although diagnostic criteria for NMO are available, there is still a need for biomarkers, predicting disease development and progression to improve individually tailored treatment. CSF proteins were separated by two-dimensional electrophoresis and identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS).
