The lymphocyte/monocyte ratio predicts the efficacy of isatuximab plus pomalidomide in multiple myeloma patients.

Isatuximab, an anti-CD38 antibody, has been widely used in treatments for patients with relapsed/refractory multiple myeloma (MM). Despite its high efficacy, not all patients achieve a lasting therapeutic response with isatuximab. We tried to identify biomarkers to predict the effectiveness of isatuximab by focusing on the host's immune status before treatment. We retrospectively analyzed the cases of 134 relapsed/refractory MM patients in the Kansai Myeloma Forum database who had received only a first isatuximab treatment. Among the 134 patients, an isatuximab, pomalidomide and dexamethasone (Isa-PD) regimen, isatuximab, carfilzomib and dexamethasone (Isa-KD) regimen and isatuximab and/or dexamethasone (Isa-D) regimen were used in 112, 15 and 7 patients, respectively. The median age at treatment, number of prior treatment regimens, and progression-free survival (PFS) were 71, 6, and 6.54months, respectively. Multivariate analysis showed that the PFS under the Isa-PD regimen was longer in patients with higher lymphocyte/monocyte ratio (LMR ≥ 4), fewer prior treatment regimens (< 6), and no use of prior daratumumab treatment. The OS under the Isa-PD regimen was longer in patients with higher white blood cell counts (WBC counts ≥ 3000/μL) and higher LMR. The PFS under the Isa-D regimen was longer in patients with fewer prior treatment regimens in univariate analysis, but no parameters were correlated with PFS/OS under the Isa-KD regimen. We found that the patients with higher LMR (≥ 4) could obtain longer PFS and OS under the Isa-PD regimen. Other cohort studies of isatuximab treatment might be necessary to substantiate our results.

Sex-specific relationships of inflammatory biomarkers with blood pressure in older adults.

Emerging evidence indicates an association between blood pressure and inflammation, yet this relationship remains unclear in older adults, despite the elevated prevalence of hypertension. We investigated the association between blood pressure, high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and white blood cell (WBC) count in a cohort of 3571 older adults aged 65 and above, and 587 middle-aged participants (55-59years old). In women aged 65 and above, the relationship between inflammatory markers and blood pressure was consistent, with hs-CRP and WBC emerging as predictors of high blood pressure. For hs-CRP, the adjusted odds ratio (OR) was 1.5 (95% CI, 1.07 to 2.10, P = 0.02), and for WBC, the adjusted OR was 1.41 (95% CI, 1.02 to 1.94, P = 0.04), comparing the highest to the lowest quartiles. In men, only the WBC count was significantly associated with an increased OR for high BP (adjusted OR 1.49, 95% CI, 1.09 to 2.02, P = 0.01) across quartiles. Across the entire study population, in a fully adjusted model, all inflammatory markers were modestly associated with blood pressure levels, while the effect of being over 65years was the most significant predictor of high blood pressure (OR 1.84, 95% CI, 1.50 to 2.25, P < 0.001). The link between key inflammation markers and blood pressure in older adults varies by sex and biomarker type and may differ from the relationship observed in younger individuals. These relationships are likely to be affected by factors linked to age.

Relationship between ocular manifestations, laboratory findings, echocardiographic findings, and intravenous immunoglobulin resistance in Kawasaki disease.

This study investigates the incidence of ocular involvement in Kawasaki disease (KD) and evaluates the relationship between ocular manifestations, laboratory findings, echocardiographic findings, and intravenous immunoglobulin (IVIG) resistance. We conducted a cross-sectional study with 58 KD patients from June 2021 to March 2023. For all patients, a complete ophthalmologic examination and echocardiography were performed in the acute phase before starting the treatment. We analyzed the age, sex, mean of white blood cell (WBC) count, platelet count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), echocardiographic findings and IVIG responses for all patients and compared the group with ocular involvement with the group without involvement. The incidence of bilateral acute conjunctivitis was 70.7%, while that of acute uveitis was 30%. Patients with uveitis had significantly higher rates of Coronary artery dilatation and IVIG resistance, as well as higher mean levels of WBC, platelet, and CRP compared to those without uveitis. (P < 0.05). Additionally, the age of patients with uveitis involvement was lower than those without involvement. No significant relationships existed between ESR, AST, or ALT values and uveitis (P > 0.05). Furthermore, no significant correlations existed between any examined items and acute bilateral conjunctivitis. Uveitis in KD is significantly associated with coronary artery dilatation, IVIG resistance, higher WBC count, platelet count, and CRP level.

A comparative analysis of the clinical and genetic profiles of blast phaseBCR::ABL1-negative myeloproliferative neoplasm and acute myeloid leukemia, myelodysplasia-related.

The classic Philadelphia chromosome-negative myeloproliferative neoplasms (Ph (-) MPNs), have variable potential for progression to the blast phase (MPN-BP) of the disease. Except initiated by distinct driver mutations, MPN-BP frequently carry similar genetic abnormalities defining acute myeloid leukemia myelodysplasia-related (AML-MR). Because of dissimilar initial pathogenesis, MPN-BP and AML-MR are retained under different disease categories. To determine if separately classifying these entities is justified, we compare MPN-BP with AML-MR patients based on mutational landscape and clinical parameters. 104 MPN-BP patients and 145 AML-MR patients were identified with available clinical, cytogenetic, and genetic data. AML-MR patients presented with a higher blast count (median, 51% vs. 30%) while MPN-BP patients had higher WBC counts, platelet counts and bone marrow cellularity (all p<0.0001). Patients with MPN-BP showed similar genetic mutations with similar mutation pattern (functional domain, hotspot and locus involved by the mutations) but a different mutation rate from AML-MR, with more frequent JAK2, CALR, MPL, ASXL1, IDH2, SETBP1 and SRSF2 mutations and less frequent TP53 and DNMT3A mutations. The overall survival (OS) of MPN-BP (OS post-BP-progression) is comparable to that of AML-MR (median OS, 9.5 months vs. 13.1 months, p=0.20). In addition, the subgroups of MPN-BP show similar OS as AML-MR. When harboring certain mutation such as TP53, ASXL1, DNMT3A, TET2, RUNX1, IDH1, IDH2, EZH2, U2AF1, BCOR and SRSF2, MPN-BP and AML-MR patients carrying the same somatic mutation show no difference in OS. MPN-BP and AML-MR harbor similar somatic mutations and clinical outcomes, suggesting a unified clinical disease entity.

The Epidemiology, Management and Therapeutic Outcomes of Subdural Empyema in Neonates with Acute Bacterial Meningitis.

Background: Subdural empyema is one of the more serious complications of bacterial meningitis and therapeutic challenges to clinicians. We aimed to evaluate the clinical characteristics, treatment, and outcome of subdural empyema in neonates with bacterial meningitis. Methods: A retrospective cohort study was conducted in two medical centers in Taiwan that enrolled all cases of neonates with subdural empyema after bacterial meningitis between 2003 and 2020. Results: Subdural empyema was diagnosed in 27 of 153 (17.6%) neonates with acute bacterial meningitis compared with cases of meningitis without subdural empyema. The demographics and pathogen distributions were comparable between the study group and the controls, but neonates with subdural empyema were significantly more likely to have clinical manifestations of fever (85.2%) and seizure (81.5%) (both p values < 0.05). The cerebrospinal fluid results of neonates with subdural empyema showed significantly higher white blood cell counts, lower glucose levels and higher protein levels (p = 0.011, 0.003 and 0.006, respectively). Neonates with subdural empyema had a significantly higher rate of neurological complications, especially subdural effusions and periventricular leukomalacia. Although the final mortality rate was not increased in neonates with subdural empyema when compared with the controls, they were often treated much longer and had a high rate of long-term neurological sequelae. Conclusions: Subdural empyema is not uncommon in neonates with acute bacterial meningitis and was associated with a high risk of neurological complications, although it does not significantly increase the final mortality rate. Close monitoring of the occurrence of subdural empyema is required, and appropriate long-term antibiotic treatment after surgical intervention may lead to optimized outcomes.

The Clinical Management of Leukocytospermia in Male Infertility: A Narrative Review

A major global health concern, male infertility affects 8–12% of couples globally. Leukocytospermia is a complicated illness that is distinguished from other reasons causing male infertility by having high white blood cell counts in semen. The complex mechanisms behind leukocytospermia’s effects on sperm function and fertility are examined in this review. Leukocytospermia induces oxidative stress and reactive oxygen species (ROS) that impair DNA integrity, mitochondrial function, cytoplasmic extrusion, and sperm quality overall. Leukocytospermia is exacerbated by non-infectious factors, such as substance abuse and varicocele, even though genital tract infections are a common cause. The usefulness and dependability of diagnostic techniques range from immunochemistry to direct counting. Although there is still disagreement on the most effective course of action, clinical-care techniques, such as antioxidant supplementation and antibiotic therapy, attempt to address underlying causes and reduce ROS-induced damage. Prospectively, the combination of artificial intelligence with the latest developments in artificial reproductive technologies presents opportunities for more precise diagnosis and customized treatments.

The benefits of interval appendectomy and risk factors for nonoperative management failure in the therapeutic strategy for complicated appendicitis.

Emergency surgery (ES) for complicated appendicitis (CA) is associated with high morbidity. Interval appendectomy (IA) decreases this rate; however, nonoperative management (NOM) is not always successful. Some patients require unplanned ES due to NOM failure (IA failure: IA-F). This study aimed to verify the benefits of IA and to evaluate the risk factors for NOM failure. Patients diagnosed with CA who underwent surgery between January 2012 and December 2021 were included in this study. We compared the surgical outcomes of the ES group with those of the IA success (IA-S) and IA-F groups. We also analyzed 14 factors that predicted NOM failure. Among 302 patients, the rate of severe complications (Clavien-Dindo grade ≥ III) was significantly higher in the ES group (N = 165) than in the IA-S group (N = 102). The rates were equal between the ES (N = 165) and IA-F (N = 35) groups. NOM was successful in 110 patients and failed in 27. Lack of abscesses, comorbidities, high WBC count, and free air were independent risk factors for NOM failure. Considering the benefits of IA and the non-inferior surgical outcomes of IA-F compared to ES, IA is a good therapeutic strategy for CA. However, in patients exhibiting four independent risk factors for NOM failure, careful monitoring of unplanned ES is necessary.

Time course of cardiac rupture after acute myocardial infarction and comparison of clinical features of different rupture types.

This study aimed to investigate the time course of cardiac rupture (CR) after acute myocardial infarction (AMI) and the differences among different rupture types. We retrospectively analyzed 145 patients with CR after AMI at Shanxi Cardiovascular Hospital from June 2016 to September 2022. Firstly, according to the time from onset of chest pain to CR, the patients were divided into early CR (≤24 h) (n = 61 patients) and late CR (>24 h) (n = 75 patients) to explore the difference between early CR and late CR. Secondly, according to the type of CR, the patients were divided into free wall rupture (FWR) (n = 55) and ventricular septal rupture (VSR) (n = 90) to explore the difference between FWR and VSR. Multivariate logistic regression analysis showed that high white blood cell count (OR = 1.134, 95% CI: 1.019-1.260, P = 0.021), low creatinine (OR = 0.991, 95% CI: 0.982-0.999, P = 0.026) were independently associated with early CR. In addition, rapid heart rate (OR = 1.035, 95% CI: 1.009-1.061, P = 0.009), low systolic blood pressure (OR = 0.981, 95% CI: 0.962-1.000, P = 0.048), and anterior myocardial infarction (OR = 5.989, 95% CI: 1.978-18.136, P = 0.002) were independently associated with VSR. In patients with CR, high white blood cell count and low creatinine were independently associated with early CR, rapid heart rate, low systolic blood pressure, and anterior myocardial infarction were independently associated with VSR.

Heterogeneous associations between interleukin-6 receptor variants and phenotypes across ancestries and implications for therapy

The Phenome-Wide Association Study (PheWAS) is increasingly used to broadly screen for potential treatment effects, e.g., IL6R variant as a proxy for IL6R antagonists. This approach offers an opportunity to address the limited power in clinical trials to study differential treatment effects across patient subgroups. However, limited methods exist to efficiently test for differences across subgroups in the thousands of multiple comparisons generated as part of a PheWAS. In this study, we developed an approach that maximizes the power to test for heterogeneous genotype–phenotype associations and applied this approach to an IL6R PheWAS among individuals of African (AFR) and European (EUR) ancestries. We identified 29 traits with differences in IL6R variant-phenotype associations, including a lower risk of type 2 diabetes in AFR (OR 0.96) vs EUR (OR 1.0, p-value for heterogeneity = 8.5 × 10–3), and higher white blood cell count (p-value for heterogeneity = 8.5 × 10–131). These data suggest a more salutary effect of IL6R blockade for T2D among individuals of AFR vs EUR ancestry and provide data to inform ongoing clinical trials targeting IL6 for an expanding number of conditions. Moreover, the method to test for heterogeneity of associations can be applied broadly to other large-scale genotype–phenotype screens in diverse populations.

Inflammatory biomarkers as predictors of systemic vs isolated pocket infection in patients undergoing transvenous lead extraction

BackgroundCardiovascular implantable electronic device (CIED) infections are a common indication for device extraction. Early diagnosis and complete system removal are crucial to reduce morbidity and mortality. The lack of clear infectious symptoms makes the diagnosis of pocket infections challenging and may delay referral for extraction. ObjectiveWe aim to determine if inflammatory biomarkers can help diagnose CIED isolated pocket infection. MethodsWe performed a retrospective analysis of all patients undergoing transvenous lead extraction for CIED infection at UCSD from 2012 to 2022 (n= 156). Patients were classified as systemic infection (n=88) or isolated pocket infection (n=68). Prospectively collected pre-operative procalcitonin (PCT), C-reactive protein (CRP), and white blood cell count (WBC) were compared between groups. ResultsPairwise comparisons revealed that the systemic infection group had a higher PCT than the control group (p<0.001), and the pocket infection group (p=0.009). However, there was no significant difference in PCT value between controls and isolated pocket infection subjects. Higher WBC was only associated with systemic infection when compared to our control group (p=0.018). ConclusionIn patients diagnosed with CIED infections requiring extraction, inflammatory biomarkers were not elevated in isolated pocket infection. Inflammatory markers are not predictive of the diagnosis of pocket infections, which ultimately requires a high level of clinical suspicion.

Impact of Hemoglobin Level, White Blood Cell Count, Renal Dysfunction, and Staphylococcus as the Causative Organism on Prediction of In-Hospital Mortality from Infective Endocarditis.

Infective endocarditis (IE) is a highly fatal disease in cases of delayed diagnosis and treatment, although its incidence is low. However, there have been few single-center studies in which the risk of in-hospital death from IE was stratified according to laboratory findings on admission and the organism responsible for IE. In this study, a total of 162 patients who were admitted to our hospital during the period from 2009 to 2021, who were suspected of having IE according to the modified Duke classification, and for whom IE was confirmed by transesophageal echocardiography were retrospectively analyzed. Patients were observed for a mean-period of 43.7 days with the primary endpoint being in-hospital death. The in-hospital death group had a lower level of hemoglobin (Hb), higher white blood cell (WBC) count, lower level of estimated glomerular filtration rate (eGFR), and higher frequency of Staphylococcus being the causative agent than those in the non-in-hospital death group. In overall multivariate analysis, Hb, WBC count, eGFR, and Staphylococcus as the causative agent were identified to be significant prognostic determinants. IE patients with Hb < 10.6 g/dL, WBC count > 1.4 × 104/μL, eGFR < 28.1 mL/minute/1.7 m2, and Staphylococcus as the causative agent had significantly and synergistically increased in-hospital death rates compared to those in other IE patients. Low level of Hb, high WBC count, low eGFR, and Staphylococcus as the causative agent of IE were independent predictors of in-hospital mortality, suggesting that these 4 parameters may be combined to additively stratify the risk of in-hospital mortality.

Emerging Clinical Features of Acute Mastoiditis in Israel: A Registry Based Cohort.

Acute mastoiditis (AM) is a severe infection in the young population, with possible life-threatening complications. This study aimed to characterize AM presentation, symptoms and signs, complications, and management, over a period of 10 years. This large-scale population-based cohort studied "Clalit Health Care" records, to include patients <18 years diagnosed with AM, hospitalized between the years 2008-2018. After validation, we investigated clinical symptoms and signs, pneumococcal vaccination status, complications, laboratory and microbiological parameters, imaging, antibiotic treatment and surgical interventions. AM was diagnosed in 1189 patients, mean age of 2.71 years and 591 (49.71%) were female. Most presented with protrusion of pinna (83.1%), retro auricular redness (73.5%) and fever (71.8%). Patients <2 years of age had more symptoms (3.8 ± 1.4, opposed to 3.6 ± 1.5, P = 0.006) and showed higher white blood cell count and C-reactive protein values. Local and intracranial complications occurred in 233 (20.8%) and 75 (6.5%) patients, respectively. Complications were associated with increased white blood cell count and C-reactive protein and related to bacterial type, specifically Fusobacterium necrophorum (P < 0.0001), for which 50% had an intracranial complication. Between the years 2008-2018, Streptococcus pneumoniae-positive cultures decreased (30.9% to 10.3%, P > 0.0001) as opposed to group-A Streptococcus (10.9% to 30.9%, P = 0.002). This study shows a difference in AM appearance in the <2 years population and the association between white blood cell count, C-reactive protein and microbiology results with the occurrence of a complication. This may play a role in the management process, such as imaging and intervention needs. Although performed during the pneumococcal vaccine era, the disease microbiology was shown to change significantly throughout the study.

Idiopathic chronic intestinal pseudo-obstruction syndrome is strongly associated with low serum levels of vitamin D.

Idiopathic chronic intestinal pseudo-obstruction (CIPO) is associated with intestinal inflammation and malabsorption and may cause serum vitamin D deficiency. We aimed to assess whether there is an association between idiopathic CIPO and serum levels of 25-hydroxy-vitamin D. Consecutive patients with confirmed diagnosis of idiopathic CIPO were prospectively enrolled and matched with healthy controls by gender, age, and BMI. Median serum level of 25-hydroxy-vitamin D of patients with CIPO was compared with that of healthy subjects using the Wilcoxon signed-rank test for matched samples. A total of 35 patients with CIPO and 35 matched healthy subjects were enrolled. All patients with CIPO had a 25-hydroxy-vitamin D deficiency with serum levels <12 ng/ml. The median serum level of vitamin D was significantly lower in patients with CIPO than in healthy controls (5.7 vs. 29.7 ng/ml, P < 0.0001). Serum level of vitamin D was not associated with gender ( P = 0.27), age ( P = 0.22), BMI ( P = 0.95), high (>10 000 × ml) WBC count ( P = 0.08), or high (>5 mg/l) C-reactive protein ( P = 0.87) among patients with CIPO. CIPO seems to be strongly associated with low serum levels of 25-hydroxy-vitamin D.

Evaluation of the Effect of Fluid and Electrolyte Therapy on Electrolytes and Acidosis Resolution Time in Diabetic Ketoacidosis

Objective: Fluid replacement and insulin infusion are the cornerstones of treatment of diabetic ketoacidosis, but the optimal volume, rate of infusion, and electrolyte content of fluid replacement have been controversial. The aim of this study was to investigate the effects of treatment on pH, bicarbonate (HCO3), anion gap, chloride, and potassium levels as well as time to resolution of acidosis in children with diabetic ketoacidosis. Material and Methods: Ninety-six episodes with diabetic ketoacidosis between January 2015-December 2017 were evaluated. Results: The mean resolution time of acidosis was 13.4±7.1 hours. Anion gap was returned to normal in 68 (70.8%) episodes at the 4th hour of treatment with a mean of 11±4.2 mmol/L. Episodes with potassium phosphate (KPO4) replacement resulted in a faster increase in pH and a significantly shorter resolution time of acidosis (p&amp;lt;0.001). Acidosis persisted at the 16th hour of treatment in episodes with lower pH, lower serum bicarbonate (HCO3) and higher white blood cell (WBC) counts on admission (p&amp;lt;0.001, p=0.003 p=0.033, respectively). Hyperchloremia (Cl/Na ratio &amp;gt; 0.79) was observed in 97% of cases after 8 hours of treatment. Conclusion: Although the value of the anion gap in predicting acidosis is controversial, severe DKA episodes and high white blood cell count at admission; potassium replacement with high amounts of chloride and KCl containing fluids given during treatment have been associated with a longer recovery time of acidosis.

Treatment status of tyrosine kinase inhibitor for newly-diagnosed chronic myeloid leukemia: a domestic multi-centre retrospective real-world study

Objective: To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China. Methods: Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed. Results: 6 893 patients in CP (n=6 453, 93.6%) or AP (n=440, 6.4%) receiving initial imatinib (n=4 906, 71.2%), nilotinib (n=1 157, 16.8%), dasatinib (n=298, 4.3%) or flumatinib (n=532, 7.2%) -therapy. With the median follow-up of 43 (IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance (n=1 055, 15.3%), intolerance (n=248, 3.6%), pursuit of better efficacy (n=168, 2.4%), economic or other reasons (n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph(+) ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph(+) ACA, poorer TFS; Ph(+) ACA, poorer OS. Conclusion: At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Yenidoğanlarda Uzamış Sarılıkta İdrar Yolu Enfeksiyonunun Sıklığı ve Rolü

Objective: The study aims to investigate the frequency and role of urinary tract infection (UTI) in prolonged jaundice in preterm and term neonates.&#x0D; Materials and Methods: This retrospective study occurred at Zeynep Kamil Maternity and Children's Hospital in Istanbul between January 2014 and April 2018. The study involved 391 neonates who presented to our outpatient clinics with prolonged jaundice. UTI was defined as urine culture growth of at least 10.000 colony-forming units per millilitre (CFU/ml) in samples obtained via urethral catheterization. Birth weight, sex, gestational age, chronological age, laboratory results, hospital courses of patients, ultrasound findings and phototherapy history were recorded. &#x0D; Results: UTI frequency was found to be 2.8% in 391 neonates with prolonged jaundice. Nine of them were male (81.8%), and 2 were female (18.2%). Eight patients with UTI (72.7%) were term and 3 (29.3%) were preterm. History of phototherapy, presence of leukocyturia or nitrituria, white blood cell count, and thrombocyte counts were significantly higher in the UTI group.&#x0D; Conclusion: Prolonged jaundice may be the first sign of UTI in neonates. Routine urine culture in neonates with prolonged jaundice may be useful, especially in those with a history of phototherapy and high white blood cell and thrombocyte counts.

Values of White Blood Cell Count and C-Reactive Protein in Diagnosis of Acute Appendicitis

Background and objectives. Acute appendicitis is one of the most common surgical emergencies. Accurate diagnosis of acute appendicitis is based on careful history, physical examination, and laboratory investigation. The purpose of this study is to investigate the value of white blood cells (WBC) and C-reactive protein (CRP) in the diagnosis of acute appendicitis. Methods. A retrospective analysis of 350 files of patients who underwent appendectomy was conducted. Selected files were those patients who were admitted to ALmasara clinic Tripoli Libya between Aug 2011 to July 2023, ages of patients ranged from 18 to 80 years. Statistical analysis was performed using SPSS version 26 software. A statistical procedure was implemented to compare the hematologic parameters in two groups (Males and Females) to determine if there was any significant difference between them. Means of WBC, Neutrophil, Lymphocyte and CRP were compared between two groups by an independent one-way analysis of variance (ANOVA). Results. This study consisted of 350 participants who were diagnosed with appendicitis. The results showed that about (69.4%) of appendicitis patients exhibited a high white blood cell count (leukocytosis). Slightly over half (52.6%) of the participants had an elevated neutrophil percentage (neutrophilia). Approximately (64.3%) of the appendicitis patients had decreased lymphocyte percentage (lymphopenia). In relation to CRP values, the study showed that most participants (76.5%) had positive CRP results. Conclusion. Individuals with appendicitis have higher levels of leukocytes, neutrophils, and C-reactive protein, and decreased lymphocyte counts. Elevated WBC and CRP values together provide a better specificity and positive predictive value than individual markers.

Characteristics and Outcomes of Failure to Thrive in Pediatric Patients Referred to the King Abdulaziz Medical City Pediatric Clinic.

Failure to thrive (FTT) in pediatric populations is a diagnostic challenge with implications for growth and development. Despite its prevalence, detailed epidemiological data, especially concerning organic versus non-organic etiologies, are sparse.This study examines the prevalence, characteristics, and outcomes of organic and non-organic FTT in a pediatric outpatient setting at King Abdulaziz Medical City, Jeddah. This retrospective chart review included pediatric patients aged three months to 14 years diagnosed with FTT at KAMC from 2016 to 2023. FTT was defined by weights below the 3rd percentile or a decline across two major growth percentiles. Patients were stratified into organic and non-organic FTT groups based on predefined criteria. Prevalence rates, clinical characteristics, and outcomes were compared to draw distinctions between the two categories. Out of 349 evaluated patients, organic FTT was present in 160 patients (45.8%), with gastrointestinal conditions and endocrine disorders being the most common etiologies. Non-organic FTT, accounting for 189 (54.2%) of cases, was primarily associated with inadequate nutritional intake and behavioral factors. Notably, the non-organic FTT group exhibited a significantly higher rate of condition resolution (45.0%) compared to their organic counterparts (32.5%). Furthermore, significant laboratory parameter differences were noted, indicating a higher white blood cell count in organic cases, among other findings. Non-organic FTT was more prevalent and demonstrated higher resolution rates, suggesting better outcomes with timely intervention and appropriate care strategies. The study advocates for increased educational efforts for caregivers and healthcare providers and calls for further research to explore effective management protocols for FTT.

Immuno-Hematological and Biochemical Changes in Patients with Tuberculosis in Dessie Comprehensive Specialized Hospital, Dessie, Ethiopia.

Tuberculosis (TB) is a serious worldwide health issue, particularly in developing nations like Ethiopia. Patients with tuberculosis experience a range of hematological, immunological, and biochemical alterations. The purpose of this study was to evaluate immunological, hematological, and biochemical alterations of newly diagnosed TB patients at Dessie comprehensive specialized hospital, Dessie, Ethiopia. A comparative, cross-sectional study was carried out to evaluate the immuno-hematological and biochemical changes in patients with tuberculosis at Dessie comprehensive specialized hospital from January to July 2018. One hundred sixty-four (164) newly diagnosed TB patients, and 80 apparently healthy controls were included consecutively. The variables were expressed in frequency, percentage, and mean ± SD. To compare mean ± SD of the groups or within the groups, we used an independent sample t-test. Statistical significance was defined as a P value less than 0.05. Male TB patients had significantly high mean absolute WBC count, neutrophil count, lymphocyte, platelet count, and systemic immune-inflammation compared with male healthy controls (P=0.001, P=0.011 P=0.021, P=0.001, and P=0.018, respectively). The mean platelet count of female TB patients was significantly higher than that of the female control group (P=0.015). However, mean RBC counts, Hgb, HCT, and MPV of TB patients were significantly lower than those of male (p<0.001) and female healthy controls (P=0.022, 0.015, and 0.001, respectively). The TB patients had developed anemia (23.8%), WBC abnormalities (29.3%), thrombocytosis (11.6%), and thrombocytopenia (9.8%). The cases had significantly higher mean alanine amino transferase, total bilirubin, and glucose level, but the mean total protein, alkaline phosphatase, and total cholesterol of cases were significantly lower than healthy control groups. TB patients in this study showed significant alterations in a number of hematological and biochemical profiles. This indicates that hematological and biochemical profiles should be monitored and properly interpreted for the differential diagnosis of tuberculosis and evaluation of response to treatment.

Construction and evaluation of short-term and long-term mortality risk prediction model for patients with sepsis based on MIMIC-IV database.

Given the high incidence and mortality rate of sepsis, early identification of high-risk patients and timely intervention are crucial. However, existing mortality risk prediction models still have shortcomings in terms of operation, applicability, and evaluation on long-term prognosis. This study aims to investigate the risk factors for death in patients with sepsis, and to construct the prediction model of short-term and long-term mortality risk. Patients meeting sepsis 3.0 diagnostic criteria were selected from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database and randomly divided into a modeling group and a validation group at a ratio of 7꞉3. Baseline data of patients were analyzed. Univariate Cox regression analysis and full subset regression were used to determine the risk factors of death in patients with sepsis and to screen out the variables to construct the prediction model. The time-dependent area under the curve (AUC), calibration curve, and decision curve were used to evaluate the differentiation, calibration, and clinical practicability of the model. A total of 14 240 patients with sepsis were included in our study. The 28-day and 1-year mortality were 21.45% (3 054 cases) and 36.50% (5 198 cases), respectively. Advanced age, female, high sepsis-related organ failure assessment (SOFA) score, high simplified acute physiology score II (SAPS II), rapid heart rate, rapid respiratory rate, septic shock, congestive heart failure, chronic obstructive pulmonary disease, liver disease, kidney disease, diabetes, malignant tumor, high white blood cell count (WBC), long prothrombin time (PT), and high serum creatinine (SCr) levels were all risk factors for sepsis death (all P<0.05). Eight variables, including PT, respiratory rate, body temperature, malignant tumor, liver disease, septic shock, SAPS II, and age were used to construct the model. The AUCs for 28-day and 1-year survival were 0.717 (95% CI 0.710 to 0.724) and 0.716 (95% CI 0.707 to 0.725), respectively. The calibration curve and decision curve showed that the model had good calibration degree and clinical application value. The short-term and long-term mortality risk prediction models of patients with sepsis based on the MIMIC-IV database have good recognition ability and certain clinical reference significance for prognostic risk assessment and intervention treatment of patients.
