BACKGROUND: This study investigated clinical and laboratory characteristics of human bocavirus type 1 (HBoV1)-plastic bronchiolitis (PB), Mycoplasma pneumoniae (MP)-associated plastic bronchitis (PB) and MP-NPB in children, highlighting inflammation, coagulation, and bronchoscopic needs.
METHODS: Data on preschool children with PB during HBoV1 or MP infection were collected, comparing MP-PB to severe Mycoplasma pneumoniae pneumonia.
RESULTS: Compared with the MP-PB group, the HBoV1-PB group, with younger children, had significantly milder clinical symptoms but higher WBC counts (p = .028). The MP-PB group exhibited notably elevated Fibrinogen (p = .045) and d-dimer levels (p < .001). When contrasting the MP-PB with the MP-NPB group, children in MP-PB group still had higher levels of d-dimer and increased inflammatory indicators such as C-reactive protein, procalcitonin, lactate dehydrogenase, and interleukin-6, which were significantly elevated compared with the MP-NPB group. MP-PB showed a higher prevalence of plastic bronchial casts in lower lobes (p = .016) and a dominance of neutrophils in BALF cytology. Additionally, children in the MP-PB group tended to undergo a greater number of bronchoscopies.
CONCLUSIONS: This study identifies key differences in plastic bronchitis in children due to HBoV1 and MP, highlighting HBoV1\'s milder inflammation in younger kids and MP\'s link to severe inflammatory and coagulation responses, guiding clinical diagnosis and treatment.

OBJECTIVE: To investigate the relationship between C-reactive protein and albumin ratios (CAR) and all-cause and cardiovascular disease(CVD)-specific mortality in individuals with coronary heart disease(CHD).
METHODS: The data from 1895 patients were extracted from the National Health and Nutrition Examination Survey (NHANES) database from 1999-2010. We used weighted COX regression analyses to explore the association between CAR, all-cause, and CVD-specific mortality. Restricted cubic spline(RCS) regression models and threshold effects analysis were used to analyze nonlinear relationships. Subgroup analyses were also performed to explore these relationships further.
RESULTS: During a mean follow-up of 115.78 months, 61.48% of deaths occurred, and 21.85% were due to CVD. After adjusting for potential confounders, each 1-unit increase in CAR was associated with a 65% increase in all-cause mortality and a 67% increase in CVD-specific mortality. The RCS model revealed a non-linear association between CAR and the risk of all-cause mortality and CVD-specific mortality in CHD patients (all non-linear P < 0.001). Threshold effects analysis identified inflection points in regression models of all-cause mortality (0.04, P < 0.001) and CVD-specific mortality (0.05, P = 0.0024). The interaction tests found sex, smoking and diabetes influenced the association between CAR and all-cause mortality and sex, smoking and HF influenced its association with CVD-specific mortality (all P < 0.05).
CONCLUSIONS: There was a nonlinear association between CAR and all-cause mortality and CVD mortality in patients with CHD, with a higher hazard ratio before the inflection point. Sex, smoking, diabetes, and HF might have an effect on the associations between CAR and death risks.

BACKGROUND: The allometric body shape index (ABSI) and hip index (HI), as well as multi-trait body shape phenotypes, have not yet been compared in their associations with inflammatory markers. The aim of this study was to examine the relationship between novel and traditional anthropometric indexes with inflammation using data from the European Prospective Investigation into Cancer and Nutrition (EPIC) and UK Biobank cohorts.
METHODS: Participants from EPIC (n = 17,943, 69.1% women) and UK Biobank (n = 426,223, 53.2% women) with data on anthropometric indexes and C-reactive protein (CRP) were included in this cross-sectional analysis. A subset of women in EPIC also had at least one measurement for interleukins, tumour necrosis factor alpha, interferon gamma, leptin, and adiponectin. Four distinct body shape phenotypes were derived by a principal component (PC) analysis on height, weight, body mass index (BMI), waist (WC) and hip circumferences (HC), and waist-to-hip ratio (WHR). PC1 described overall adiposity, PC2 tall with low WHR, PC3 tall and centrally obese, and PC4 high BMI and weight with low WC and HC, suggesting an athletic phenotype. ABSI, HI, waist-to-height ratio and waist-to-hip index (WHI) were also calculated. Linear regression models were carried out separately in EPIC and UK Biobank stratified by sex and adjusted for age, smoking status, education, and physical activity. Results were additionally combined in a random-effects meta-analysis.
RESULTS: Traditional anthropometric indexes, particularly BMI, WC, and weight were positively associated with CRP levels, in men and women. Body shape phenotypes also showed distinct associations with CRP. Specifically, PC2 showed inverse associations with CRP in EPIC and UK Biobank in both sexes, similarly to height. PC3 was inversely associated with CRP among women, whereas positive associations were observed among men.
CONCLUSIONS: Specific indexes of body size and body fat distribution showed differential associations with inflammation in adults. Notably, our results suggest that in women, height may mitigate the impact of a higher WC and HC on inflammation. This suggests that subtypes of adiposity exhibit substantial variation in their inflammatory potential, which may have implications for inflammation-related chronic diseases.

Developing the portable CRP detection technologies that are suitable for point-of-care (POC) and primary care management is of utmost importance, and advancing the electrochemical immunosensors hold promise for POC implementation. Nevertheless, non-specific adsorption of numerous interfering proteins in complex biological media contaminates immunosensors, thereby restricting the reliability in detection efficacy. In this study, a three-dimensional flower-leaf shape amyloid bovine serum albumin/gold nanoparticles/polyaniline (AL-BSA/AuNPs/PANI) coating on the surface of the electrode was developed, which demonstrated strong anti-adsorption properties against bovine serum albumin, plasma, and cells. The immunosensor exhibited a good linear relationship to CRP response, featuring a detection limit of 0.09 μg/mL, consistent with clinical reference range. In addition, the CRP immunosensor demonstrated excellent specificity in other inflammation-related proteins and commendable anti-interference performance for CRP detection in plasma and whole blood tests. Importantly, by combining the development of a USB flash disk-type portable electrochemical workstation with a reagent-free mode, the developed CRP electrochemical immunosensor delivered ideal results in clinical samples. The anti-fouling performance, sensitivity and specificity of the immunosensor, as well as its flexible test modes in clinical samples, provide important scientific basis for developing POC detection technologies of vital biomarkers in complex biological media.

OBJECTIVE: It is still debatable which is the least invasive approach to the hip joint in arthroplasty for a femoral neck fracture (FNF). We compared the traditional direct lateral approach (DLA) with the direct anterior approach (DAA) regarding creatine kinase (CK), C-reactive protein (CRP), and hemoglobin (Hb).
METHODS: In a randomized controlled trial, 130 elderly patients with dislocated FNFs treated with total hip arthroplasty (THA) were included. CK, CRP, and Hb were measured preoperatively and on postoperative days 1 to 4 and were compared between the DAA and DLA groups using repeated measures mixed-effect models.
RESULTS: The CK level was significantly higher on the 1st postoperative day in the DLA group, 597 U/L (95% confidence interval [CI] 529-666) vs 461 U/L (CI 389-532), estimated mean difference (MD) 136 U/L (CI 38-235). The CRP levels were significantly higher on postoperative days 3 and 4 in the DLA group, 207 mg/L (CI 189-226) vs 161 mg/L (CI 143-180), estimated MD 46 mg/L (CI 19-72) and 162 mg/L (CI 144-181) vs 121 (CI 102-140), estimated MD 41 mg/L (CI 15-68). Blood loss, expressed as difference in Hb, did not differ between the groups.
CONCLUSIONS: In an elderly population with FNFs, we found that the DAA, compared with the DLA, results in less CK and CRP increase, but no change in Hb.

BACKGROUND: Dental caries remains one of the most prevalent diseases worldwide, affecting 29.4% of the global population. Despite numerous efforts to diagnose, predict, and prevent dental caries, the incidence continues to rise. Salivary biomarkers provide a non-invasive means for early detection of various oral conditions. C-reactive protein (CRP) is a key marker, elevated in both oral and general inflammatory conditions such as diabetes, periodontitis and oral squamous cell carcinoma. Considering the emerging connection between oral and systemic health, it is worth exploring the various factors associated with this widespread disease. This study investigates the association between CRP levels and dental caries in the United States population, utilizing data from the National Health and Nutrition Examination Survey (NHANES).
METHODS: The study analyzed data from the 2015-2018 NHANES cycles, focusing on a nationally representative sample of individuals aged 30 years and above. Weighted multivariable negative binomial and logistic regression analyses were employed to explore the relationship between dental caries and CRP levels, adjusting for age, gender, race, education level, diabetes status, and gum disease.
RESULTS: The results of the negative binomial regression analysis demonstrated a positive association between higher CRP levels and an increased mean number of dental caries (Adjusted Mean Ratio [AMR] = 1.7; 95% CI: 1.3 - 2; P: < 0.001). The logistic regression analysis showed that individuals with higher CRP levels have a 50% increase in the odds of developing dental caries (AOR: 1.5, CI: 1.2 - 1.9; P: < 0.01).
CONCLUSIONS: The results of this cross-sectional study of the U.S. population highlight the positive association between high CRP levels and increased dental caries. These findings contribute to the growing body of evidence supporting the integration of oral and systemic health care. Further research is necessary to deepen our understanding of the mechanistic relationship between CRP levels and dental caries.

Microsystems represent an alternative but proficient approach of analysis outside the laboratory, and their use could help in reducing the impact of pre-analytical errors, in particular in challenging newborn samples. The study purpose is to compare the Horiba Microsemi CRP LC-767G system for rapid 3-part complete blood count (CBC) and C-reactive protein (CRP) determination with the laboratory reference systems (respectively Sysmex XN-9100™ and Roche Cobas® c702) in samples of adult patients and newborns hospitalized in the neonatal intensive care unit (NICU) samples. The comparison between the analyzers was performed through Passing-Bablok regression analysis and Bland-Altman plot. One hundred eighty-three blood samples were analyzed. The regression analysis results, performed in the newborn (n = 70) and in adult (n = 113) populations, showed a good agreement between the instruments. The evaluation of the Bland-Altman plots showed comparable values of bias < 10% for most of the parameters, but not for MPV, lymphocyte, and monocyte count.
CONCLUSIONS: The comparison between the Microsemi CRP LC-767G system and the laboratory instrumentations demonstrated comparable results. The Microsemi CRP LC-767G system provides reliable analytical data and faster turnaround time, particularly useful in NICU.
BACKGROUND: • Microsystems for point-of-care testing (POCT) represent an alternative but proficient approach of analysis outside the laboratory, in order to perform a rapid, safe, and exhaustive evaluation for critical patients\' management, acting as a valid support for treatment in acute care.
BACKGROUND: • The Microsemi CRP LC-767G system can represent an alternative but effective testing approach outside the laboratory, particularly in NICU, to reduce the impact of pre-analytical errors on newborn samples.

The rapid and sensitive indicator of inflammation in the human body is C-Reactive Protein (CRP). Determination of CRP level is important in medical diagnostics because, depending on that factor, it may indicate, e.g., the occurrence of inflammation of various origins, oncological, cardiovascular, bacterial or viral events. In this study, we describe an interferometric sensor able to detect the CRP level for distinguishing between no-inflammation and inflammation states. The measurement head was made of a single mode optical fiber with a microsphere structure created at the tip. Its surface has been biofunctionalized for specific CRP bonding. Standardized CRP solutions were measured in the range of 1.9 µg/L to 333 mg/L and classified in the initial phase of the study. The real samples obtained from hospitalized patients with diagnosed Urinary Tract Infection or Urosepsis were then investigated. 27 machine learning classifiers were tested for labeling the phantom samples as normal or high CRP levels. With the use of the ExtraTreesClassifier we obtained an accuracy of 95% for the validation dataset. The results of real samples classification showed up to 100% accuracy for the validation dataset using XGB classifier.

OBJECTIVE: To identify the factors associated with normal leukocyte count and C-reactive protein (CRP) in adults with acute appendicitis.
METHODS: A retrospective cohort study included patients aged 18-60 years after surgeries for acute appendicitis. Convenience sampling was used to select medical records, and variables such as age, sex, weight, height, origin, self-medication, diabetes (DM2), high blood pressure (HBP), type of appendicitis, duration of illness, preoperative time, type of appendectomy, operative time, and hospital stay were analyzed. Patients were categorized into those with normal and abnormal inflammatory parameters. The SPSS version 28 software was used for analysis.
RESULTS: We included 333 patients; 11.11% ones had normal inflammatory parameters. Both groups had mean age of approximately 33 years. Men comprised 56.76% and 57.43%in both groups, respectively. The abnormal group had shorter mean preoperative time, and catarrhal appendicitis was more common in the normal group. Multivariate analysis revealed that rural origin and self-medication were significantly associated with normal inflammatory parameters.
CONCLUSIONS: The prevalence of normal inflammatory parameters in acute appendicitis patients was 11.11%. Rural origin, self-medication, shorter preoperative time, and catarrhal appendicitis were significantly associated with normal inflammatory parameters in this context.
UNASSIGNED: Выявить факторы, связанные с нормальным количеством лейкоцитов и уровнем С-реактивного белка (СРБ) у взрослых с острым аппендицитом.
UNASSIGNED: В ретроспективное когортное исследование были включены пациенты в возрасте 18—60 лет, перенесшие операции по поводу острого аппендицита. Оценили такие переменные, как возраст, пол, вес, рост, происхождение, самолечение, диабет (СД2), высокое артериальное давление, тип аппендицита, продолжительность заболевания, предоперационный период.

UNASSIGNED: Мы включили 333 пациента. У 11,11% показатели воспаления были нормальными. Больные обеих групп имели средний возраст около 33 лет. Мужчины составили 56,76 и 57,43% в обеих группах соответственно. В группе аномальных значений средний предоперационный период был короче, а катаральный аппендицит чаще встречался в группе нормальных значений. Многофакторный анализ показал, что сельское происхождение и самолечение были в значительной степени связаны с нормальными параметрами воспаления.
UNASSIGNED: Распространенность нормальных показателей воспаления у больных острым аппендицитом составила 11,11%. Сельское происхождение, самолечение, более короткий предоперационный период и катаральный аппендицит были значимо связаны с нормальными параметрами воспаления.

<b>Introduction:</b> Loop ileostomy reversal (LIR) procedure is still associated with a relatively high risk of complications. Surgical site infection (SSI) is the most common complication in this group of patients. SSI leads to prolonged hospital stays, delays the adjuvant therapy, and increases hospital costs.<b>Aim:</b> The aim of the study was to analyze the risk factors for SSI in patients following loop ileostomy reversal procedure.<b>Material and methods:</b> A single-center retrospective analysis was conducted in a tertiary reference center. Finally, 65 patients following loop ileostomy reversal procedure performed between 2018 and 2022 were enrolled in the study. Data were collected retrospectively based on the available medical charts. The study group comprised 23 women (35%) and 42 men (65%) with a mean age of 48.9 14.5 years and a mean body mass index of 24.3 4.9 kg/m² . The most common indication for index surgery was ulcerative colitis (33%) and colorectal cancer (29%). Preferably, handsewn anastomosis was performed (n = 42; 64.6%).<b>Results:</b> The most important parameter evaluated in the above study was the diagnosis of surgical site infection, which influenced e.g. hospitalization after surgery, the need for antibiotic therapy, or C-reactive protein (CRP) values. Nine patients (13.8%) were diagnosed with SSI during their hospital stay (more than 86% without SSI). In the group with SSI, hospital stay exceeded 13 days compared to almost 6 days in the group without SSI (P = 0.00009). The time of the procedure had a statistically significant correlation with antibiotic therapy introduction (P = 0.01). The type of intestinal anastomosis had a significant impact on the operative time (P = 0.0011) and the time of hospital stay after surgery (P = 0.04).<b>Conclusions:</b> Most of the analyzed clinical factors were directly related to the impact on the duration of postoperative hospitalization. The duration of hospitalization is an independent and undeniable factor increasing the risk of other postoperative complications and significantly increasing the cost of hospitalization. Another factor that has a large clinical impact on postoperative treatment is the presence of comorbidities which make patients more likely to develop SSI, CRP increase, or the need for antibiotic therapy. An important factor was the level of CRP, the elevated value of which may be a predictor of many negative aspects in postoperative treatment.
