Logistic Regression Model Analysis Research Articles

A classification system for identifying persons with an unknown cardiovascular disease (CVD) status for a multiracial/ ethnic Caribbean population.

The need for classification systems for cardiovascular disease (CVD) that is population-specific is important towards understanding the clinical disease and diagnostics associated with the disease. This paper presents the form and validation results of this classification system. The survey data used was captured from 778 participants, 526 persons with no prior CVD, and 252 who reported prior CVD. Binomial logistic regression and Discriminant analysis were utilised to develop classification models. This classification system provided a general measure of severity of disease by utilising scores estimated from two algorithms developed from 13 routine physiologic measurements, along with demographic information of age and ethnicity, inter alia, and previous health status. For each model, specific score ranges were identified, which gave the best classification for those with a prior CVD incident (higher scores) and for others labelled as non-CVD (lower scores). The two classification models (Logistic Regression Model and Discriminant Analysis Model) developed had high area under the receiver-operating characteristic (AUROC) values (98% & 99%) and sensitivity (86 and 90%), which improved discrimination between Non-CVD and CVD participants and, more importantly, correctly classified a greater proportion of CVD participants. New to this type of research was the estimation and detailed evaluation of a range of scores, labelled non-differentiating, which fell in the middle of the spectrum and which contained the higher-end scores for the non-CVD individuals and the lower-end scores for CVD patients, all of whom were incorrectly classified, based on their prior history. The classification system of scores is able to differentiate the CVD status of individuals, with good predictability, and could assist physicians with recommending different treatment plans. The two models in this classification system each individually outperformed the three established models in terms of the strength of their correct classifications of individuals with or without prior reported CVD incidents. More importantly, they have smaller non-differentiating ranges than the three known models and, in that range, the two new models have lower CVD/non-CVD ratios suggesting they are more likely to misclassify non-CVD individuals compared to CVD patients, which is a more benign misclassification. Further, when used in combination, the two models increased the sensitivity, in classifying individuals of different ethnicities, beyond that of either one used independently or of any of the three standard European/North American models. These efforts will be instrumental in advancing personalised CVD management strategies and improving health outcomes across diverse populations.

New-generation tetracyclines for severe macrolide-resistant Mycoplasma pneumoniae pneumonia in children: a retrospective analysis

BackgroundMacrolide-resistant Mycoplasma pneumoniae (MRMP) strains are increasingly prevalent, leading to a rise in severe Mycoplasma pneumoniae pneumonia incidence annually, which poses a significant threat to children’s health. This study aimed to compare the effectiveness and safety of oral minocycline and doxycycline for the treatment of severe MRMP pneumonia in children.MethodsThis retrospective analysis included children treated for severe MRMP pneumonia at the Pediatric Department of Tongji Hospital, Shanghai, China, between September 2023 and January 2024 using minocycline and doxycycline. The patients were divided into four groups according to treatment: oral doxycycline alone (DOX group), oral minocycline alone (MIN group), oral doxycycline with intravenous glucocorticoids (DOXG group), and oral minocycline with intravenous glucocorticoids (MING group). Student’s t-test, Mann–Whitney U test, and χ2 or Fisher’s exact tests were used for group comparisons.ResultsA total of 165 patients were included in this study: 84 received minocycline, and 81 received doxycycline. The DOX group had higher fever resolution rates within 24, 48, and 72 h compared to the MIN group (63.2% vs. 31.8%, 79.0% vs. 63.6%, and 100% vs. 90.9%, respectively; all p < 0.05). The DOXG group showed higher fever resolution rates within 24 and 48 h than the MING group (92.3% vs. 83.4%, 100% vs. 92.7%, all p > 0.05). There were no statistically significant differences in time to imaging improvement, cough improvement, and disappearance of wet rales between groups, regardless of glucocorticoid combination. The longer the duration of fever prior to tetracycline therapy, the greater the likelihood of hypoxemia (p = 0.039) and a greater than two-fold elevation in the D-dimer level (p = 0.004).Univariate binary logistic regression model analysis revealed that CRP and erythrocyte sedimentation rate at disease onset were associated with defervescence within 24 h after treatment with tetracyclines alone (p = 0.020, p = 0.027), with erythrocyte sedimentation rate also influencing defervescence within 48 h (p = 0.022).ConclusionDoxycycline treatment resulted in a higher rate of defervescence than minocycline. Prompt treatment reduced the probability of pleural effusion, hypoxemia, pulmonary atelectasis, and D-dimer levels > 2 times the reference value.

Association of dietary patterns with serum uric acid and hyperuricemia in Chinese adults

Objective: To analyze the dietary patterns of Chinese adults and explore the relationship with serum uric acid (SUA) and hyperuricemia (HUA). Methods: A total of 9 358 adults were selected in the 2018 China Health and Nutrition Survey. Dietary intake data were collected by three consecutive 24-hour dietary recalls and weighing method. The social demographic information of the survey subjects was obtained through questionnaire surveys. The dietary patterns were extracted using factor analysis, and the relationship between dietary patterns and SUA was analyzed using multiple linear regression analysis. The correlation between HUA and dietary patterns was analyzed using logistic regression analysis models. Results: Four dietary patterns were identified: northern (high intakes of wheat, other cereals,and tubers); modern (high intakes of fruit, dairy, eggs, and nuts); southern (high intakes of rice and vegetables);animal food-wine (high intake of organ meats, seafood, and wine). The multiple linear regression analysis results showed that the northern pattern was negatively correlated with SUA (β=-0.438, 95%CI: -0.500--0.376); the modern pattern was negatively correlated with SUA (β=-0.134, 95%CI: -0.219--0.049); the southern model was significantly correlated with higher SUA (β=0.146, 95%CI: 0.079-0.214); the animal food-wine pattern was positively correlated with SUA (β=0.188, 95%CI: 0.123-0.252). Logistic regression analysis showed that compared with the northern model score Q1 group, the risk of developing HUA was reduced in Q3 and Q4 groups, with ORs values of 0.777 (95%CI: 0.650-0.929) and 0.509 (95%CI: 0.423-0.613), respectively; and compared with the modern model score Q1 group, the higher the scores in Q3 and Q4 groups, the HUA was lower, with ORs of 0.793 (95%CI: 0.660-0.953) and 0.768 (95%CI: 0.631-0.934), respectively. Compared with the animal food-wine pattern score Q1 group, the risk of developing HUA was increased in both Q3 and Q4 groups (Q3 group: OR=1.224, 95%CI: 1.012-1.480; Q4 group: OR=1.312, 95%CI: 1.086-1.584). Conclusions: Dietary patterns are associated with HUA. The northern and modern patterns are related to lower SUA levels and reduced risk of HUA, while the animal food-wine pattern increases the risk of HUA.

The characteristics of pediatric primary retroperitoneal teratoma and the influencing factors of perioperative complications

To explore the characteristics of pediatric primary retroperitoneal teratoma and the influencing factors of perioperative complications. The clinical data, imaging data, pathology results, perioperative complications, etc of patients with primary retroperitoneal teratoma admitted and treated at Shanxi Children's Hospital from March 2013 to September 2023 were retrospectively analyzed. The patients were divided into no complication group and complication group according to whether there were perioperative complications. The differences between the two groups were compared, and the influencing factors of complications were analyzed by multivariate logistic regression model. A total of 33 patients were included in this study, including 7 males and 26 females, with an age of [M (Q1, Q3), 9.0 (4.0, 24.0)] months. Nineteen cases had tumors located in the left upper abdomen and 14 cases in the right upper abdomen, among which 17 cases grew across the midline, with the maximum tumor diameter of (12.9±4.5) cm. All patients had anatomical displacement of retroperitoneal vessels and organs: the number of anatomical displaced arteries was 3 (3, 4), the number of anatomical displaced veins was 4 (3, 5), the number of anatomical displaced organs was 5 (4, 6). Pathologic examination revealed 28 mature teratomas (Grade 0 and Grade 1) and 5 immature teratomas (Grade 2 and Grade 3). There were 18 cases in no complication group and 15 cases in the complication group. The incidence of perioperative complications was 45.5% (15/33). The number of tumors crossing the midline (6/18 vs 11/15, P=0.037), the number of tumors adhering closely to the surrounding tissues (7/18 vs 12/15, P=0.033), the number of anatomical displaced veins [4 (3, 4) vs 5 (4, 5), P=0.001], and the number of anatomical displaced organs [4 (3, 5) vs 6 (5, 6), P=0.001] were significantly different between the two groups. Multivariate logistic regression model analysis showed that the number of anatomical displaced organs (OR=8.781, 95%CI: 2.155-35.784, P=0.002) was the influencing factor for perioperative complications of pediatric primary retroperitoneal teratoma.

Long-term efficacy of mepolizumab in patients with eosinophilic granulomatosis with polyangiitis: a propensity score matching analysis in the multicenter REVEAL cohort study.

Mepolizumab (MPZ) has demonstrated efficacy in clinical trials for eosinophilic granulomatosis with polyangiitis (EGPA); however, few studies compare the disease course between patients treated with MPZ (MPZ group) and those who were not treated with MPZ (non-MPZ group) in real-world settings. This study aimed to compare the disease course and outcomes between the two groups and assess the long-term efficacy of MPZ in a multicenter cohort in Japan. Methods: We enrolled 113 EGPA patients registered in the cohort until June 2023. Data on clinical characteristics, disease activity, organ damage, treatments, and outcomes were retrospectively collected. To minimize potential confounding factors, we conducted propensity score matching (PSM). After PSM, 37 pairs of matched patients were identified. Clinical characteristics, including age at disease onset, sex, disease duration at last observation, antineutrophil cytoplasmic antibody positivity at disease onset, Birmingham Vasculitis Activity Score (BVAS) at disease onset, and Five-factor score at disease onset, were comparable between the groups. The median BVAS at the last observation was 0 in both groups; however, more cases in the non-MPZ group exhibited elevated BVAS, resulting in a significantly higher BVAS in the non-MPZ group at the last observation (median; MPZ group: 0, non-MPZ group: 0, p=0.028). The MPZ group had significantly lower glucocorticoid (GC) doses at the last observation (median; MPZ group: 4 mg/day, non-MPZ group: 5 mg/day, p=0.011), with a higher proportion achieving a GC dose ≤ 4 mg/day at the last observation (MPZ group: 51.4%, non-MPZ group: 24.2%, p=0.027). Three models of multivariable logistic regression analyses were performed to identify factors associated with GC doses ≤ 4 mg/day at the last observation. In all models, achieving a GC dose ≤ 4 mg/day was positively associated with MPZ administration and inversely associated with asthma at disease onset. Finally, we evaluated the survival rates between the groups, and the 5-year survival rates were significantly higher in the MPZ group compared to the non-MPZ group (MPZ group: 100%, non-MPZ group: 81.3%, p=0.012). Mepolizumab not only contributes to disease activity control but also reduces the GC dose, which may lead to improved survival in EGPA patients.

Prevalence of and Risk Factors for Hearing Impairment in Craniofacial Microsomia

BackgroundWhile ear anomalies and hearing impairment are common in patients with craniofacial microsomia (CFM), their prevalence, characteristics, and relationship to speech-language development remain unclear. PurposeThis study analyzed the prevalence and risk factors for hearing impairment in patients with CFM. Study Design, Setting, SampleThis retrospective cohort study included patients with unilateral or bilateral CFM from a single center between January 1980 and July 2023 who had evidence of a hearing assessment at <18 years. Exclusion criteria were inconclusive CFM diagnosis by clinical examination and/or radiographs or incomplete medical records. Predictor VariablesThe predictor variables included presence or absence of cleft lip and/or palate, laterality of CFM, and external ear and mandibular anomaly scores measured using the Orbit, Mandible, Ear, Nerve, and Soft Tissue (OMENS) and Pruzansky-Kaban classifications. Main Outcome VariablesPrimary outcome variable was hearing impairment, measured through air and bone conduction audiometry and categorized by type, severity, and side. Secondary outcome variable was speech-language delay, evaluated through assessments of expressive and receptive language skills, vocabulary, speech intelligibility, general articulation, and phonological speech. CovariatesThe covariates included sex and age at first hearing assessment. AnalysesLogistic regression models were used to analyze the effect of predictors on outcomes. P-value <0.05 was considered significant. ResultsThe sample included 213 patients (61.5% male). Hearing assessments were performed at a mean age of 4.6 ± 4.8 years. Hearing impairment was found in 183 (85.9%) and was predominantly conductive (n=130, 91.5%). Of subjects with hearing impairment, 158 (86.3%) had external ear anomalies (P<0.001). In patients with unilateral CFM, 38 (21.8%) had bilateral hearing loss and 9 (5.2%) had contralateral-only hearing loss. Both M3 and E3 scores were associated with the presence and severity of hearing loss (P=0.01 and P<0.001, respectively). There was no significant association between hearing impairment and speech-language development (P>0.05). Conclusion and RelevanceAlthough the severity of mandibular and external ear anomalies was significantly associated with the prevalence and severity of hearing loss, clinicians should remain alert for concomitant or isolated contralateral hearing loss, given the high prevalence of hearing loss in ears without ipsilateral facial involvement or external abnormalities.

Factor associated with postoperative complications of inguinal lymph node dissection for penile cancer Test

Background: Inguinal lymph node dissection (ILND) is the standard of care for palpable, biopsy-proven lymph node metastases or high-risk groups for nonpalpable lymph nodes in the treatment of penile cancer. ILND is associated with a significant incidence of complications and adverse events, specifically wound complications. Few studies have identified risk factors related to postoperative ILND complications. Objective: The objective of this study was to assess the prevalence of 30-day postoperative complications and to identify risk factors associated with postoperative complications of ILND for penile cancer. Materials and Methods: This was a retrospective review of medical records for all patients who had ILND for penile cancer between January 2012 and December 2022. According to the modified Clavien–Dindo classification, the 30-day postoperative complications were collected. Using an ordinal univariate logistic regression model and multivariate analysis, potential risk variables for complications were determined. Results: A total of 60 patients were performed ILND. Sixty percent of the patients had a postoperative complication including wound infection 50%, wound dehiscence 36.7%, skin necrosis 26.6%, lymphocele 33.3%, leg edema 46.7%, and scrotal edema 16.7%. Higher grade of modified Clavien–Dindo classification was associated with body mass index (BMI) (odds ratio [OR] = 1.15; P = 0.03), diabetes mellitus (OR = 3.13; P = 0.04), American Society of Anesthesiologist classification ≥3 (OR = 1.14; P = 0.03), radical ILND (OR = 1.57; P = 0.01), and bilateral ILND (OR = 1.60; P = 0.02). In multivariate analysis, a higher grade of modified Clavien–Dindo classification was correlated with BMI (OR = 1.48; P = 0.01) and bilateral ILND (OR = 4.56; P = 0.01). Conclusion: ILND is associated with high rates of complication. The severity of the modified Clavien–Dindo classification was associated with BMI and bilateral ILND.

Idiopathic cervical abscesses in dogs follow seasonal trends and geographic risk factors, predominantly affecting young, large breeds: a case-control study of 67 dogs in New England.

Describe and identify risk factors and spatiotemporal trends associated with the development of idiopathic cervical abscesses (CAs) in dogs in the Cape Cod region. The authors hypothesized that CAs without an external communicating tract would have a seasonal trend and would not be associated with identifiable foreign material. 67 dogs. Retrospective observational case-control study enrolling dogs between 2016 and 2020. Compiled patient information included age, breed, sex, weight, date of presentation, and ZIP code. Statistical evaluation was performed by use of multivariate logistic regression modeling and spatiotemporal analyses with government-compiled land cover data. Control dogs were randomly selected in a 3:1 ratio to cases. 67 cases were investigated. The final multivariable logistic regression model found a significant seasonal effect, with most cases in September (OR, 4.80; 95% CI, 1.91 to 12.02). Spatial analyses revealed increased risk in a cluster of 13 ZIP codes, with OR of 4.40 (95% CI, 1.95 to 9.95). Weight was a risk factor; each additional kilogram was associated with an 18.8% increase in odds (OR, 1.188; 95% CI, 1.053 to 1.341) until a maximum risk at 15 kg. Younger dogs were at greater odds; for each additional year of age, the odds of having CAs were reduced by 8.9% (OR, 0.911; 95% CI, 0.837 to 0.991). No foreign material inciting cause was identified in any of the 67 cases. Idiopathic CAs should be a differential for young, large-breed dogs with cervical swelling in the Northeastern US. This study documented seasonality, geographical trends, and signalment predispositions for idiopathic CAs.

Characteristics of altered biventricular hemodynamics after arterial switch operation for patients with d-transposition of the great arteries with preserved ejection fraction: a four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) study.

The long-term monitoring of biventricular function is essential to identify potential functional decline in patients following the arterial switch operation (ASO). The underlying pathophysiological mechanisms responsible for altered biventricular hemodynamics in ASO patients are not yet well understood. This study sought to: (I) compare the biventricular kinetic energy (KE) and vorticity of ASO patients and age- and sex-matched controls; (II) investigate the associations of four-dimensional (4D) flow biventricular hemodynamics parameters and neo-aortic root dilation, supravalvular pulmonary stenosis, and pulmonary artery transvalvular pressure difference. A total of 34 patients with dextro-transposition of the great arteries (D-TGA) who underwent ASO, and 17 age- and gender-matched healthy controls were prospectively recruited for this study. All the subjects underwent cine and 4D flow and late gadolinium enhancement scans, and all the patients underwent echocardiography within two weeks of cardiovascular magnetic resonance (CMR) imaging. The following four flow components were analyzed: direct flow, retained inflow, delayed ejection flow, and residual volume. In addition, the following six phasic blood flow KE parameters, normalized to the end-diastolic volume (EDV) and vorticity, were analyzed for both the left ventricle (LV) and right ventricle (RV): peak systolic phase, average systolic phase, peak diastolic phase, average diastolic phase, peak E-wave phase, and peak A-wave phase. The independent sample Student's t-test, Mann-Whitney U-test, univariable and multivariable stepwise regression analyses, intra and inter-observer variability analyses were used to compare patients and controls. In relation to the LV, the D-TGA patients had significantly decreased average vorticity, peak systolic vorticity, systolic vorticity, diastolic vorticity, and peak A-wave vorticity compared to the controls (all P<0.01). In relation to the RV, the pulmonary stenosis group had significantly increased peak E- and A-wave kinetic energy normalized to the end-diastolic volume (KEiEDV), and peak and average vorticity compared to the non-pulmonary stenosis group (all P<0.05). in the multivariable logistic regression model analysis, diastolic KEiEDV, peak E-wave KEiEDV peak A-wave KEiEDV, and average vorticity were associated a with transvalvular pressure difference (β=13.54, P<0.001 for diastolic KEiEDV; β=105.26, P<0.001 for peak E-wave KEiEDV; β=-49.36, P=0.027 for peak A-wave KEiEDV; and β=-56.37, P<0.001 for average vorticity). We found that 4D flow biventricular hemodynamics were more sensitive markers than the ejection fraction in the postoperative D-TGA patients. The RV diastolic KEiEDV parameters and average vorticity were risk factors for pulmonary artery obstruction in the multivariable model.

Impact of serum cholinesterase on calcified nodules in patients with stable coronary artery disease.

Calcified nodules (CNs) are an advanced stage of coronary calcification that can have significant clinical implications. We investigated factors associated with CNs, the etiology of which is not fully understood. We retrospectively evaluated 619 patients with stable coronary artery disease who underwent intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI). CNs in the culprit lesion were evaluated via IVUS, and all-cause mortality and major cardiovascular and cerebrovascular events (MACCEs) were compared between the CN and non-CN groups. The CN group (n = 40 patients) had a significantly lower survival rate and a higher incidence of MACCE than the non-CN group (P = 0.020 and P < 0.001, respectively). Multivariate logistic regression analysis models revealed that chronic kidney disease and serum cholinesterase (ChE) level were associated with CN formation [odds ratio (OR): 3.15, 95% confidence interval (CI): 1.30-7.69, P = 0.001 and OR: 0.94, 95% CI: 0.88-0.99, P = 0.042]. The optimal cutoff of serum ChE level as per the receiver operating characteristic curve was 309 units/l (Area under the curve = 0.67, sensitivity = 93%, specificity = 40%, P = 0.001). The low-ChE group divided according to the optimal cutoff value showed significantly higher cumulative incidence of MACCEs after PCI than the high-ChE group as per Kaplan-Meier analysis. The presence of CNs is significantly associated with a poor prognosis and MACCE after PCI among patients with stable coronary artery disease. Serum ChE levels may affect CN formation.

Interaction between trouble sleeping and diabetes on metabolic dysfunction-associated fatty liver disease and liver fibrosis in adults results from the National Health and Nutrition Examination Survey 2017-2018.

Metabolic dysfunction-associated fatty liver disease (MAFLD), trouble sleeping, and diabetes, as major public health problems, were closely related. The study examined the interaction between trouble sleeping and diabetes on MAFLD and liver fibrosis in adults with MAFLD. The data were obtained from the National Health and Nutrition Examination Survey 2017-2018. Multivariate logistic regression model and subgroup analyses were conducted to assess the relationship between either trouble sleeping or diabetes on MAFLD and liver fibrosis. Relative excess risk due to interaction (RERI), attributable proportion of interaction (AP), and synergy index (S) were utilized to assess the additive interaction. Ultimately, 3747 participants were included, with 2229 known MAFLD subjects. Compared with participants without diabetes, those with diabetes had a higher risk of MAFLD [odds ratio (OR) = 5.55; 95% confidence interval (CI) = 4.07-7.56] and liver fibrosis risk (OR = 3.61; 95% CI = 2.67-4.89). We also found a significant association of trouble sleeping with an increased risk of MAFLD (OR = 1.54; 95% CI = 1.17-2.02) and liver fibrosis risk (OR = 1.51; 95% CI = 1.06-2.16), compared with those without trouble sleeping. Moreover, there was a significant interaction between diabetes and trouble sleeping on MAFLD [RERI = 1.76 (95% CI: -0.22 to 3.73), AP = 0.35 (95% CI: 0.08-0.63), S = 1.80 (95% CI: 1.02-3.16)] and liver fibrosis risk [RERI = 1.79 (95% CI: 0.37-3.21), AP = 0.44 (95% CI: 0.20-0.69), S = 2.44 (95% CI: 1.18-5.08)]. The findings highlight that trouble sleeping and diabetes had a synergistic effect on MAFLD and liver cirrhosis. The study highlights the importance of addressing both trouble sleeping and diabetes management in adults to mitigate the risk of MAFLD and liver fibrosis.

High levels of blood lipid and glucose predict adverse prognosis in patients with aneurysmal subarachnoid hemorrhage

ObjectiveWe conducted a retrospective study on the prognostic factors of aneurysmal subarachnoid hemorrhage (aSAH) patients in the author's Hospital from January 2019 to May 2023. To discuss the association of the blood lipid and glucose levels of patients with the prognosis of aSAH, and verify that high blood lipid and glucose levels are important factors affecting adverse prognosis. MethodsAll patients with aSAH were collected as the case group, which was divided into two groups according to the modified Rankin Scores (mRS), the good prognosis group (Group A, mRS ＜ 3) and the adverse prognosis group (Group B,mRS ≥3). The clinical data of age, gender, accompanied chronic diseases (hypertension, diabetes), smoking, drinking, Glasgow Coma Scale (GCS), Hunt-Hess (H-H) grade, Modified Fisher grade, total cholesterol (TC) , triglyceride (TG) , high-density cholesterol lipoprotein (HDL-C) , low-density cholesterol lipoprotein (LDL-C) , blood glucose (BG) , responsible aneurysm diameter and location were recorded too. Correlations between blood lipid and glucose levels and Modified Fisher grade were assessed by the Spearman correlation analysis. The receiver operating characteristic (ROC) curve was utilized to evaluate the diagnostic efficacy. The effect of blood lipid and glucose levels on adverse prognosis was analyzed by Logistic regression models. ResultA total of 259 patients with aSAH were enrolled. The average age of all patients is (56.54 ± 10.52) years, including 96 males and 163 females. They were divided into Group A (n = 146) and Group B (n = 113). Univariate analysis results show that age, the levels of TC, TG, LDL-C, and BG were higher in Group B (P < 0.05). Besides, Group B had more severe GCS, H-H grade, and Modified Fisher grade than Group A, and a higher proportion of intracranial aneurysms with larger diameter (P < 0.05). Correlation analysis showed that TC, TG, LDL-C, and BG levels were positively correlated with Modified Fisher grade (P < 0.05) and H-H grade (P < 0.05). Multivariate logistic regression model analysis showed that high level of Modified Fisher grade (OR = 0.079, 95%CI: 0.027–0.230) , high level of H-H grade (OR = 0.204, 95%CI: 0.067–0.622) , TC (OR = 10.711, 95%CI: 2.457–46.700) , LDL-C (OR = 0.178, 95%CI: 0.039–0.823) and BG (OR = 1.273, 95%CI: 1.012–1.602) increased the risk of adverse prognosis. The AUC of “H-H grade”, “Modified Fisher grade”, “TC level”, “LDL-C level” and “BG level” was 0.822, 0.885, 0.860, 0.772, and 0.721, respectively, in the ROC curve. ConclusionModified Fisher grade, H-H grade, TC, LDL-C, and BG levels at admission were independent predictors of adverse prognosis of aSAH. Besides, TC, LDL-C, and BG levels were positively correlated with Modified Fisher grade and Hunt-Hess grade. What's more, high levels of TC, LDL-C, and BG combined with Modified Fisher grade and H-H grade can identify high-risk groups with adverse prognoses in aSAH patients.

Nomogram to predict methotrexate treatment success in ectopic pregnancy.

To evaluate clinical factors prior to methotrexate (MTX) treatment for tubal ectopic pregnancy and to apply the data to a prediction model for treatment success. A retrospective cohort study was conducted during 2014-2022. Of the 808 patients with a tubal ectopic pregnancy, 372 with a β-hCG level less than 5000 IU/L were treated with a single dose of MTX and were included in this study. Pretreatment factors, including patient characteristics, initial β-hCG level, and sonographic parameters, were compared between those who achieved complete resolution and those who needed additional MTX or surgical intervention. A logistic regression model and multivariable analysis were used to predict success. A graphic nomogram was generated to represent the model. Complete resolution of the ectopic pregnancy was achieved in 290 (77.9%) patients after a single dose of MTX. A second dose or surgical intervention was required for 82 (22.0%): 49 (13.2%) received a second dose of MTX and 33 (8.9%) underwent laparoscopic salpingectomy. In the MTX Success group compared to the MTX Failure group, the median β-hCG levels were lower (746 vs 1347 IU/L, P < 0.001) and the presence of a yolk sac and a fetal pole were less frequent. The predictive model, based on significant variables, includes initial β-hCG concentration and the visibility of a yolk sac or fetal pole. Analysis with cross-validation techniques revealed that the model was both accurate and discriminative. A predictive nomogram was developed to predict the success of single-dose MTX treatment for tubal ectopic pregnancy.

Clinical Outcomes of Sickle Cell Disease Patients With Myocardial Infarction Undergoing Percutaneous Coronary Intervention: A Nationwide Analysis.

Sickle cell disease (SCD) patients are predisposed to various cardiovascular complications due to the nature and progression of the disease; the clinical outcomes of SCD patients experiencing myocardial infarction (MI) and undergoing percutaneous coronary intervention (PCI) are not well known. This study aims to explore a comprehensive nationwide analysis of the clinical outcomes in SCD patients who have suffered an MI and subsequently undergone PCI. Italso identifies potential complications and compares their outcomes with non-SCD counterparts with the same interventions. We conducted a retrospective analysis of SCD patients who have suffered an MI and subsequently undergone PCI using the National Inpatient Sample (NIS) database from 2016 to 2020. The primary outcome was mortality, while the secondary outcomes were the average length of stay, comorbid conditions, and cardiovascular outcomes. Logistic, linear, and Poisson regression model analysis applied for outcomes and adjusting co-founders. P-value <0.05 was considered significant. A total of 775 patients were analyzed for MI who had PCI with SCD, with a mean age of 58±1.06years. SCD patients exhibited higher rates of comorbidities, including diabetes mellitus (45.81% vs. 37.84%), obesity (23.87% vs. 20.85%), and chronic kidney disease (CKD) (29.03% vs. 17.36%). Heart failure was more common among SCD patients with 34.19% vs. 26.02% in non-SCD patients(OR 1.5, CI 1.1-2.1, p-value=0.02). Other cardiovascular complications such as stroke, ventricular arrhythmias, atrial fibrillation, pulmonary edema, cardiogenic shock, cardiac arrest, and mortality did not significantly differ betweenSCD and non-SCD(P-values >0.05). The study observed that SCD patients experienced a significantly higher incidence of heart failure than non-SCD patients. This implies that SCD patients undergoing PCI for MIexhibit distinct clinical outcomes compared to their non-SCD counterparts.

Controlling nutritional (CONUT) score for nutritional screening in kidney transplant recipients

Purpose: Nutrition is severely impaired in individuals with renal impairment, and transplant often ameliorates this condition. In this study, we aimed to evaluate the controlling nutritional status (CONUT) score of kidney transplant (KT) recipients. Materials and methods: Using the data from the nephrology transplant unit, we analyzed 188 patients whose data on the constituents of the CONUT score were available. We included KT individuals with at least one lymphocyte count and total cholesterol and albumin concentrations. This data has been used to calculate the CONUT score. The decrease of lymphocyte counts and total cholesterol was determined with 0, 1, 2, and 3 points, and the reduction of albumin was assigned with 0, 2, 4, and 6 points in agreement with disease severity. Patients were classified according to this score: normal, light, moderate, and severe. Results: There were 138 patients in normal, 54 in light, and three in each moderate and severe group. The CONUT score was good for regular-weight patients both before and after transplantation. All laboratory findings revealed significant differences between CONUT groups (p&lt; 0.05). The logistic regression analysis model, including cholesterol, WBC, and calcium, showed that these three parameters have a predictive value of 80%. Conclusion: After transplantation, the number of patients in the underweight group decreased when normal weight and obesity increased. However, some patients’ nutrition was not ameliorated. The CONUT score may be a useful tool for monitoring transplant patients’ nutritional status.

Kidney damage and associated risk factors in the rural Eastern Cape, South Africa: A cross-sectional study.

The colliding epidemic of infectious and non-communicable diseases in South Africa could potentially increase the prevalence of kidney disease in the country. This study determines the prevalence of kidney damage and known risk factors in a rural community of the Eastern Cape province, South Africa. This observational cross-sectional study was conducted in the outpatient department of the Mbekweni Community Health Centre in the Eastern Cape between May and July 2022. Relevant data on demography, medical history, anthropometry and blood pressure were obtained. The glomerular filtration rate was estimated using the Chronic Kidney Disease Epidemiology Collaboration Creatinine (CKD-EPICreatinine) equation and the re-expressed four-variable Modification of Diet in Renal Disease (MDRD) equation, without any adjustment for black ethnicity. Prevalence of kidney damage was defined as the proportion of individuals with low eGFR (<60mL/min per 1.73m2). The presence of proteins in the spot urine samples was determined with the use of test strips. We used the logistic regression model analysis to identify the independent risk factors for significant kidney damage. The mean (±standard deviation) age of the 389 participants was 52.3 (± 17.5) years, with 69.9% female. The prevalence of significant kidney damage was 17.2% (n = 67), as estimated by the CKD-EPICreatinine, with a slight difference by the MDRD equation (n = 69; 17.7%), while the prevalence of proteinuria was 7.2%. Older age was identified as a significant risk factor for CKD, with an odds ratio (OR) = 1.08 (95% confidence interval [CI]: 1.06-1.1, p < 0.001). Hypertension was strongly associated with proteinuria (OR = 4.17, 95% CI 1.67-10.4, p<0.001). This study found a high prevalence of kidney damage (17.2%) and proteinuria (7.97%) in this rural community, largely attributed to advanced age and hypertension, respectively. Early detection of proteinuria and decreased renal function at community health centres should trigger a referral to a higher level of care for further management of patients.

U-shaped association between hemoglobin levels and albuminuria in US adults: a cross-sectional study.

This study aimed to explore the correlation between hemoglobin levels and albuminuria in US adults. This cross-sectional investigation analyzed the National Health and Nutrition Examination Survey (NHANES) information from 2011 to 2020. Data on hemoglobin, albuminuria, and other variables were collected from all participants. The logistic-regression analyses and smoothed curves were used to substantiate the research objectives. The average age of the 8,868 participants was 49.5 ± 17.3years, and 49.3% were men. The prevalence of albuminuria was 12.1%. After adjusting for potential variables in the logistic-regression analysis models, hemoglobin (per 1g/dL increase) was inversely associated with the presence of albuminuria (odds ratio [OR], 0.92; 95% confidence interval [95%CI], 0.87-0.97). Compared with participants in quartile 3 (Q3, 14.1-15.0g/dL) for hemoglobin levels, those in the lowest quartile 1 (Q1, 6.1-13.0g/dL) and highest quartile 4 (Q4, 15.1-19.6g/dL) had adjusted ORs for albuminuria of 1.48 (95% CI, 1.19-1.85) and 1.11 (95% CI, 0.9-1.38), respectively. Our observations indicated a U-shaped association between hemoglobin levels and albuminuria, with a point of inflection at approximately 15.5g/dL. The effect sizes and CIs below and above this point were 0.853 (95% CI, 0.798-0.912) and 1.377 (95% CI, 1.055-1.797), respectively. This study indicates that the presence of albuminuria is linked to both low and high hemoglobin levels in US adults. The management of hemoglobin may benefit kidney health.

Measuring Diabetic Medication Adherence and Factors That Lead to Non-adherence Among Patients in Erbil.

Introduction T2D is a chronic and progressive disorder characterized by persistent hyperglycemia resulting from inadequate insulin secretion or utilization. The global prevalence of T2D is increasing rapidly, posing a significant health burden in many regions. In the Kurdistan region of Iraq, T2D presents a significant health burden, exacerbated by socioeconomic changes, dietary shifts, and rising obesity rates. Poor adherence to antidiabetic medications is a major factor contributing to poor glycemic control, accelerating disease progression, and increasing complications. This study aims to assess medication adherence rates among adult T2D patients in Erbil using the Kurdish version of the Morisky Medication Adherence Scale-8 (MMAS-8) and identify factors associated with non-adherence. Methods We conducted a cross-sectional study at public and private clinics in Erbil City, Kurdistan, Iraq, between May 1 and September 30, 2023. A convenience sample of 300 adult Kurdish T2D patients, aged ≥ 25 years and on antidiabetic medications for three months or more, was recruited. Data were collected using a structured questionnaire comprising sociodemographic characteristics, clinical and anthropometric measures, and medication adherence assessed by the Kurdish version of the MMAS-8. Statistical analysis included analysis of variance, Kruskal-Wallis, chi-square, and logistic regression models to identify factors associated with medication adherence. Results Of the 300 participants, 81 (27%) demonstrated high adherence, 98 (32.6%) moderate adherence, and 121 (40.3%) low adherence based on the MMAS-8. Low adherence was significantly associated with lower education (56/121, 46.3% vs. 13/81, 16.0%, p < 0.001), unemployment (73/121, 60.3% vs. 29/81, 35.8%, p = 0.008), rural residence (41/121, 33.9% vs. 10/81, 12.3%, p < 0.001), and lower income (62/121, 51.2% vs. 12/81, 14.8%, p < 0.001). High adherence was linked to better diabetes knowledge, home glucose monitoring, and exercise. High adherence was also associated with better glycemic control, with 76/81 (93.8%) of highly adherent patients achieving glycated hemoglobin (HbA1c) <7%, compared to 15/121 (12.4%) in the low adherence group (p < 0.001). Multivariate analysis identified HbA1c, dyslipidemia, and home blood glucose monitoring as independent factors associated with high adherence. Conclusions This study highlights the substantial impact of socioeconomic, behavioral, and clinical factors on medication adherence among T2D patients in Erbil. Low adherence is associated with lower education, income, and awareness of diabetes management, while high adherence is linked to improved glycemic control and reduced complications. Targeted interventions addressing these factors are essential to enhance adherence and optimize T2D management in this population.

Integrating surgical complexity and nutritional parameters to enhance prediction of postoperative complications in liver resection

BackgroundIn patients undergoing liver resection, postoperative complications remain high. We hypothesized that the incidence of postoperative complications after liver resection would be predicted well by liver resection complexity and nutritional status. MethodsWe retrospectively assessed patients undergoing liver resection at The University of Tokyo Hospital from 2011 to 2021. Liver resection procedures were categorized by surgical complexity using a 3-level complexity classification. Nutritional parameters (including cholinesterase and albumin levels) were evaluated together with well-known nutritional indexes, including the modified Glasgow Prognostic Score, prognostic nutritional index, platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, and controlling nutritional status. ResultsOf 1,258 patients, 570 (44.5%) experienced postoperative complications, with 506 (39.9%) requiring treatment (Clavien–Dindo grade II or greater). Multivariate logistic regression model analyses showed that cholinesterase and albumin levels, complexity classification, and open approach were associated with postoperative complications. The cholinesterase–liver resection complexity/approach model (area under the curve, 0.634) performed significantly better in predicting complications than the prognostic nutritional index (area under the curve, 0.560; P < .001), modified Glasgow Prognostic Score (area under the curve, 0.557; P < .001), controlling nutritional status (area under the curve, 0.502; P < .001), platelet-to-lymphocyte ratio (area under the curve, 0.513; P < .001), and neutrophil-to-lymphocyte ratio scores (area under the curve, 0.515; P < .001). On the basis of the cholinesterase–liver resection complexity/approach model, estimated complications ranged from 9.6% to 53.4%, and patients with well-maintained cholinesterase levels were estimated to have a 5–15% lower probability of complications than patients with impaired cholinesterase levels. This finding was validated with an external Western cohort. ConclusionThe cholinesterase–liver resection complexity/approach model better predicted postoperative complications than nutritional indicators alone and may be useful for selecting patients who may benefit from nutritional support.

Operative outcomes 24 hours after retrograde intrarenal surgery for solitary renal calculi using a flexible and navigable suction ureteral access sheath. A prospective global multicenter study by the European Association of Urology Section on Urolithiasis.

Suction techniques showed potential to improve outcomes of retrograde intra-renal surgery (RIRS). We assessed the 24-hour stone-free rate (SFR) and complications after RIRS using flexible and navigable suction ureteral access sheaths (FANS-UAS). Sixteen centers prospectively contributed to data (August 2023-October 2023). Inclusion criteria: age ≥18 years, single renal stone, pre and 24-hour post-RIRS CT scan. Exclusion criteria were: ureteral stone, anomalous kidney, multiple stones. SFR was divided into: 1) grade A - no fragments; 2) grade B - fragments ≤2 mm; 3) grade C - fragments 2.1-4 mm; and 4) grade D - fragments >4 mm. A multivariable logistic regression analysis model was performed to assess factors associated with the odds of having grade A stone-free status. Data are expressed as median (interquartile range), absolute numbers and frequencies, odds ratio (OR), and 95% confidence interval (CI). One hundred forty-two patients with a median age of 52 years (40-61) were enrolled. 61.3% were males. Median stone volume was 1165 mm3 (656-1936). Median operative time was 48.5 (36.25-71.75) min. Transient fever (37°C-37.5°C) occurred in 10 (7%) patients. No sepsis case occurred. 96.5% of patients were stone-free (Grade A+B). Grade A SFR was 52.8%. All patients were discharged within 48 hours. Bone window (OR 3.156 95% CI 1.177-9.130, P=0.027) was the only factor significantly associated with higher odds of 100% SFR, while stone volume (OR 0.999, 95% CI 0.999-1.000, P=0.007) was significantly associated with lower odds. Imaging and clinical evidence demonstrate excellent perioperative outcomes just 24 hours post RIRS with FANS-UAS. The technique demonstrates a good safety profile, ability for immediate high SFR, and a low rate of infective complications.
