Association between hyponatremia and disease severity in pediatric urinary tract infections

BackgroundAcute urinary tract infection (UTI) is a common disease in pediatrics, with around 8% of girls and 2% of boys experiencing a UTI by age 7y/o. UTIs can range from asymptomatic bacteriuria to acute pyelonephritis (APN) in severe cases involving renal parenchymal infection. UTI patients admitted to the pediatric ward usually have more severe clinical presentation, compared to those treated in the outpatient settings. Therefore, it will be helpful to have markers that predict the severity of the disease and the likelihood of having APN.MethodsWe performed a retrospective review on all pediatric UTI/APN patients treated in the inpatient setting at a Medical Center from October 2012 to September 2022. Patients were assigned to the “hyponatremia” or “eunatremia” group according to their serum sodium concentrations. Detailed information, including renal echo, blood, and urine test results, were collected for the analysis of multivariable logistic regression model.ResultsThe study included 344 patients, of which 99 (28.8%) had hyponatremia, and 245 (71.2%) had normal serum sodium levels. The hyponatremia group had higher APN frequency, renal echo abnormality, and higher CRP level. In multivariable analysis, hyponatremia was independently associated with increased serum glucose (OR: 1.01, 95% CI: 1.00-1.03, p = 0.0365) and CRP levels (OR: 1.00, 95% CI: 1.00-1.01, p = 0.0417), without a significant increase in APN frequency as the final diagnosis.ConclusionsOur findings suggest that hyponatremia in pediatric UTI patients may indicate a more severe disease, such as APNs, higher CRP levels, or renal echo abnormalities. The complex mechanisms underlying hyponatremia and its predictive value for disease severity warrant further investigation.

Association between inflammatory markers and anemia in patients with diabetic foot ulcer.

Aim: Anemia of inflammation (AI) is common among patients with diabetic foot ulcers (DFU). This study aimed to investigate the specific relationship between inflammation indicators and anemia in patients with DFU.Materials & methods: This cross-sectional study was carried out among patients with DFU between 2018 and 2023. Clinical data were gathered before treatment. Restricted cubic spline regression was employed to investigate the non-linear associations between inflammation and anemia.Results: A total of 395 patients with Wagner grades 2-4 were enrolled in the study. About 63.54% of the patients with DFU had anemia which was primarily presented with normocytic hypopigmentation anemia. Elevated IL-6 levels (39.10-369pg/ml) were significantly associated with an increased likelihood of anemia (OR=4.84; 95% CI: 1.97-11.90). Similarly, high CRP levels (48.56-385mg/l) were linked to a higher prevalence of anemia (OR=5.01; 95% CI: 2.35-10.68). Furthermore, a nonlinear relationship was observed between CRP levels and anemia, suggesting that CRP values exceeding 53.889mg/l may trigger anemia in patients with diabetic foot ulcers.Conclusion: Inflammation is identified as an independent risk factor for AI in patients with DFU. The inflammation indicators (CRP and IL-6) and anemia exhibit an L-shaped nonlinear correlation in patients with DFU.

Early Elevated Inflammatory Markers in SARS-CoV-2 Vaccinated Patients Are Associated with Reduced Mortality, Morbidity, and Lung Injury.

Background The development of vaccines against SARS-CoV-2 has proved to be a highly successful strategy. In this work, the aim is to study the effects of the SARS-CoV-2 vaccine on the production of inflammatory markers and how this affect morbidity and mortality. Electronic medical record (EMR) data from 210 patients diagnosed with COVID-19 from November 2020 to June 2021 were collected. The admitted patients were divided into three groups, the one-dose vaccinated, two-dose vaccinated, and the non-vaccinated. All patients were moderate or severe in disease level as defined by the WHO classification. The results show that CRP was 101 ± 5.3, 97 ± 10.8, and 145 ± 17.3 (p < 0.05), fibrinogen 529 ± 16.3, 397 ± 33.8, and 610 ± 15 (p < 0.05), D-dimer 1244 ± 89, 1279 ± 297, and 1615 ± 224 (p < 0.05), ferritin was 1170 ± 122, 999 ± 202, and 1663 ± 409 (p < 0.05), IL-6 was 196 ± 12, 96 ± 5, and 580 ± 402 (NS), for the non-vaccinated, one-dose vaccinated, and two-dose vaccinated groups, respectively. The high level of CRP up to 150-200 mg/dL was more common among the surviving vaccinated patients. Oxygen supplementation, mechanical ventilation, and mortality were higher in the non-vaccinated group. Blood urea nitrogen (BUN) level was higher in the vaccinated patients, 25 ± 0.14 vs. 33 ± 6.15, respectively (p < 0.05). Inflammation markers were significantly higher in the vaccinated groups compared to non-vaccinated groups. On the other hand, extremely high levels of CRP (>200 mg/dL) were correlated with high mortality incidence.

“Rest of the folks are tired and weary”: The impact of historical lynchings on biological and cognitive health for older adults racialized as Black

Childhood structural racism may lead to poorer health and longevity for individuals racialized as Black. Racism-related stress cumulatively taxes the body resulting in worsening biological and cognitive health. This study examines the association between state-level exposure to historical lynchings (adverse childhood racism for modern older adults), with C-reactive protein (CRP, a marker of systemic inflammation), and global cognitive performance (modified TICS). We linked the percentage of lynchings of people racialized as Black at the state-level between 1882 and 1968 from the Archives at Tuskegee Institute with repeated CRP and cognitive test scores at baseline (2006/2008), year 4 (2010/2012), and year 8 (2014/2016) for a national sample of older adults in the Health and Retirement Study (N = 10,500, aged >50). In multivariable generalized estimating equation models, we compared participants (by racialized group) living in states with high lynching proportions (>50th percentile) on changes in CRP and cognitive test scores adjusting for demographics, health conditions, and behaviors. Mean age was 69 (SD = 9.9) and most participants were cisgender women (59%). On average participants racialized as non-LatinX Black living in states with high lynching proportions experienced 18.5% (95% CI 3%, 36%) higher CRP levels and −0.92 (95% CI -1.34, −0.50) lower cognitive test scores than participants racialized as non-LatinX Black that lived in states with lower lynching proportions. As artist Marvin Gaye sang in Flyin’ High (in the Friendly Sky), “Rest of the folks are tired and weary,” which describes how adverse childhood racism is associated with inflammation and dementia risk for people racialized as Black.

Gut dysbiosis and neutrophil extracellular traps in chronic heart failure

BackgroundChronic heart failure (HF) patients have reduced microbiota diversity. Leakage of microbes and their metabolites into the bloodstream may activate neutrophils. Neutrophil extracellular traps (NETs) consist of chromatin and proteases, and may contribute to HF pathogenesis. We assessed associations between circulating NETs and 1) cardiac function, 2) the degree of gut microbiota diversity and 3) gut leakage and microbial metabolites in HF patients. MethodsA cross-sectional study including 124 patients with chronic HF and left ventricular ejection fraction ≤40 %. Severe HF was defined as N-terminal pro-B-type natriuretic peptide concentrations above median. We measured citrullinated histone H3 (CitH3), myeloperoxidase- and double-stranded-DNA in the blood. Gut leakage markers included bacterial lipopolysaccharides and soluble cluster of differentiation 14. The microbial metabolites included circulating trimethylamine N-oxide and butyrate producing capacity. We used the Shannon diversity-index and a dysbiosis-index based on bacteria with altered relative abundance to characterize the gut microbiota profile. ResultsQuartile 4 of CitH3 was associated with more severe HF compared to quartiles 1–3, after adjustments for age, gender and hypertension (adjusted odds ratio [95 %CI] 3.21[1.18–8.69], p = 0.022). CitH3 was moderately associated with hypertension (p = 0.04), higher CRP levels (p = 0.016) and lower Shannon diversity index, (p = 0.039). No other NET marker associated with severe HF. ConclusionsIn chronic HF patients with reduced LVEF, high levels of CitH3 were associated with disease severity, inflammation and reduced gut microbiota diversity. Our results suggest that enhanced release of NETs could be involved in progressive HF, although the contribution of the gut microbiota seems limited in this context.

Investigating lifestyle determinants of carotid intima-media thickness: cross-sectional insights from the UK biobank cohort

Abstract Background/Introduction Carotid intima-media thickness (CIMT) is recognised as a crucial marker for cardiovascular disease (CVD) risk, inherently associated with vascular ageing and influenced by biomarkers such as elevated levels of HbA1c, dyslipidaemia, and hypertension. The significance of CIMT lies in its potential to act as a surrogate marker for CVD risk, bridging a gap in understanding the progression of vascular health. Purpose This study aims to investigate the correlation between CIMT and a composite biomarker score to enhance risk assessment and guide the prevention and treatment strategies for CVD. By examining this relationship, the study seeks to underline the importance of CIMT progression as an indicative marker for cardiovascular health. Methods A subset of participants from the UK Biobank, with valid CIMT measurements taken in 2014, was selected for this analysis. CIMT was measured through ultrasound techniques and considered the primary outcome variable, treated as continuous in the analysis. A linear regression model was used to examine the correlation between CIMT and lifestyle risk factors, with a focus on the moderating effects of sex. Results The study included 29,292 UK Biobank participants (48% female, mean age 64 years), with a mean CIMT of 687.11µm (SD 124.28). Significant predictors of CIMT were age (β=6.05) and male gender (β=13.02). Lifestyle factors such as body weight (β=0.84) and high physical activity (β=10.66) were positively correlated with CIMT. Current smokers showed a stronger association with CIMT (β=14.47) compared to former smokers (β=9.21). In females, age (β=6.07), body weight (β=0.71), CRBI score (β=9.95), and previous smoking (β=6.64) positively correlated with CIMT, while high CRP levels were negatively associated (β=-0.61). In males, significant factors included age (β=6.04), body weight (β=0.95), CRBI score (β=10.79), and smoking history, with previous smokers showing a stronger effect (β=11.67) and high physical activity notably associated with increased CIMT (β=18.73). Conclusion(s) The study's findings highlight the impact of lifestyle choices on vascular health, demonstrating that active living, maintaining a healthy weight, and abstaining from smoking can positively affect CIMT and thereby reduce CVD risk. The results confirm the importance of weight management for arterial health across all demographics and highlight the role of abnormal biomarker levels in increasing CIMT. This study contributes to a deeper understanding of the factors affecting CIMT and, by extension, cardiovascular health, advocating for targeted lifestyle interventions to mitigate CVD risk.

Coronary artery plaque characteristics in smokers assessed by intracoronary multi-modality imaging: a NIRS-IVUS guided PROSPECT II substudy

Abstract Background Smoking is a risk factor for coronary artery disease and myocardial infarction. Purpose Among patients with myocardial infarction, we hypothesized smokers would have increased prevalence of nonculprit high-risk plaque characteristics as assessed by intracoronary multimodality imaged when compared to nonsmokers. Method This is a prespecified post-hoc analysis of the PROSPECT II (Providing Regional Observations to Study Predictors of Events in the Coronary Tree). Altogether 898 patients with acute myocardial infarction with or without ST-segment elevation who after successful percutaneous coronary intervention had near-infrared spectroscopy and intravascular ultrasound imaging performed. Data on lesion location, plaque burden, and lipid content were collected. Current, former, and nonsmokers were examined regarding the presence of high-risk plaques in both culprit and nonculprit lesions as well as plaque location. High-risk plaque characteristics were defined as a maximum plaque burden (maxPB) of ≥70% and a maximum 4 mm lipid core burden index (maxLCBI4mm) of ≥324.7. Results Out of 886 patients with known smoking history, 32% were smokers, 32% former, and 37% nonsmokers. Smokers were younger (median age: smokers 59.0; former 65.5; nonsmokers 64.0 years, p&amp;lt;0.001) with fewer co-morbidities and presented more often with STEMI (% presenting with STEMI: smokers 22.2%; former 18.9%; nonsmokers 19.4%, p=0.006). LDL was similar but CRP was higher in smokers (median µg/mL: smokers 4.0; former 3.1; nonsmokers 2.9, p=0.004). In multivariate models of nonculprit lesion morphology smoking history was not associated with maxPB or maxLCBI4mm but was associated with presence of calcified nodules (OR: 2.88 (95% CI 1.46–5.69) p=0.002 [smokers vs nonsmokers]). Calcified nodules were also associated with number of years smoked (OR: 1.02 (95% CI 1.01–1.03) p=0.004). Smoking was not associated with presence of ≥1 lesions with MaxLCBI4mm, ≥ 324.7, maxPB &amp;gt;=70% or the combination of both. Smoking was not associated with presence of plaque rupture or thrombus. Right coronary artery culprit lesions were more common in smokers and former smokers (smokers 29.9%; former 30.9%; nonsmokers 21.6%; OR: 1.12 (95% CI 1.04–1.21) p&amp;lt;0.001 [smokers vs nonsmokers]). Conclusion In this prospective intracoronary multimodality imaging study of patients with recent acute myocardial infarction, smoking was not associated with a higher rate of high-risk nonculprit plaques based on lipid content by NIRS or PB by IVUS when compared to former or nonsmokers. However, smoking was associated with higher presence of IVUS-detected calcified nodules, higher CRP-levels, and the right coronary artery as it angiographically was a more common site for culprit lesions. These results indicate that the elevated risk in smokers is unrelated to vulnerable plaque morphology defined by high PB and lipid content, and instead possibly related to inflammation, calcification, or hemodynamic changes.Table 1

Clinical characteristics and prognosis of Talaromycosis marneffei associated immune reconstitution inflammatory syndrome in AIDS patients.

Immune reconstitution inflammatory syndrome (IRIS) is an inflammatory reaction that occurs in HIV/AIDS patients after antiretroviral therapy (ART) initiation. Along with immune system recovery, IRIS can overreact to existing infections or latent pathogens, causing symptoms that mimic those infections. Few studies elucidated the clinical features and prognosis of Talaromycosis marneffei (TSM)-associated IRIS in HIV/AIDS patients. The aim of our study was to evaluate the incidence, clinical characteristics, and prognosis of TSM-associated IRIS by retrospectively analyzing the clinical data of HIV/AIDS patients with TSM. A total of 224 HIV/AIDS inpatients with TSM were enrolled, aged between 19 and 81 years. Among them, 86.6% were male and 13.4% were female, of which 24 (10.7%) patients developed IRIS. In IRIS group, the median time from ART initiation to IRIS occurrence was 9.0 days (IQR, 5.0-16.8 days), with 87.5% (21/24) occurring within 2 weeks. Primary clinical manifestations included recurrent fever and exacerbation of pulmonary infection. At the onset of IRIS, 54.2% (13/24) patients were treated with intravenous dexamethasone, and 12.5% (5/24) patients were treated with oral prednisone for 1-3 weeks. No significant differences in baseline characteristics or ART regimens were observed between IRIS and non-IRIS groups; however, patients in IRIS group had higher levels of CRP, CD4+ count, and CD4+/CD8+ ratio than non-IRIS group (equivalent time point: 1-2 weeks after ART initiation) at IRIS onset. The IRIS group exhibited longer hospital stays and higher readmission rates, but equivalent mortality rates compared with non-IRIS group. IRIS is a common complication in HIV/AIDS patients with TSM, often occurring within 2 weeks after ART initiation and exhibiting more pronounced immune reconstitution. The occurrence of IRIS significantly extended the hospitalization duration and increased the rate of readmission but had no influence on the mortality rate.

Sexual Dysfunction in Women with Asthma and Associated Factors

Background: Asthma is a common chronic inflammatory airway disease. Female sexual dysfunction (FSD) is frequently seen in asthmatics but often unnoticed in clinical practice. This study evaluated the associations between asthma disease characteristics and (FSD). Methods: A total of 73 female asthma patients who visited the chest department outpatient clinic and age-matched 73 healthy controls were enrolled. All the participants completed the questionnaires: female sexual function index (FSFI), BECK depression, and BECK anxiety inventory, and underwent pulmonary function tests. Patients with asthma completed an asthma quality of life questionnaire (AQLQ) and asthma control test (ACT). FSD risk factors were analyzed using logistic regression analysis. Results: About 68.8% of asthmatics had female sexual dysfunction. BECK anxiety and FSFI scores with all six subsets were statistically significantly lower than healthy individuals in asthmatics (p &lt; 0.001). CRP levels, BECK anxiety, and depression scores had inverse (r = -0.386 r = -0.343 r = -0.286), and FEV1% had a positive correlation with FSFI total scores. About 37.5% of asthma patients with FSD were current smokers, the most compromised domain of the FSFI scale was sexual arousal with a mean of 2.94 ± 0.56 and their FEV1% was lower, and CRP was higher than the asthma patients without FSD (p &lt; 0.001, p &lt; 0.021). Smoking, high levels of CRP and BECK anxiety scores, and low FEV1% were found to be risk factors for FSD in regression analysis. Conclusions: Female sexual dysfunction is frequently present in asthma patients. Smokers, patients who have anxiety, lower FEV1% predicted values, and higher CRP levels tend to be susceptible to sexual dysfunction, which implicates inflammation as an underlying mechanism.

Characterization of Markers in Blood Tests of Patients With Pleural Effusion and Their Correlation to Different Etiologies.

To investigate the etiology of pleural effusion, a variety of examinations are performed, including invasive ones: Thoracentesis is an invasive procedure to remove fluid or air from the pleural cavity for diagnostic or therapeutic purposes. Until now, there are no blood markers that can help us diagnose the type of pleural effusion without the need for pleural puncture or drainage. The aim of this study was to investigate the relationship and the utility of the new inflammatory markers taken from complete blood count (CBC) to differentiate between the various types of pleural effusion before the invasive procedure decision. This is an observational retrospective study. Data was collected from medical records of patients aged 18-90 admitted in Ziv Medical Center, Safed, Israel that were diagnosed with pleural effusion from 2013 to 2019. Of those patients, of whom inflammatory markers from blood counts and thoracentesis results were obtained, the outcomes were compared with the diagnosis type of pleural effusion. This study involved 391 patients, 256 suffered from exudate type effusion, their median age was 72 years, while 135 suffered from transudate effusion, their median age was 80 years. Those with exudate effusion had higher levels of CRP, platelets, neutrophils, and lymphocytes in blood, whereas those with transudate effusion had higher levels of MPV and RDW in blood. Other blood markers such as NLR and PLR were not statistically significant, but were also higher in the blood of patients with exudate effusion. An evaluation of simple and inexpensive measurements of blood count such as platelets, neutrophils, lymphocytes, MPV, RDW may provide insight into the etiology of pleural effusion.

Early goal-directed renal replacement therapy in severe pneumonia associated acute kidney injury

Introduction Severe pneumonia is a crucial issue in the development of acute kidney injury (AKI). This study evaluated the efficacy of early goal-directed renal replacement therapy (GDRRT) for the treatment of severe pneumonia-associated AKI. Methods In this real-world retrospective cohort study, we recruited 180 patients with severe pneumonia who were hospitalized and received GDRRT in a third-class general hospital in East China between January 1, 2017, and December 31, 2021. Clinical data on baseline characteristics, biochemical indicators, and renal replacement therapy were collected. Patients were divided into Early and Late RRT groups according to fluid status, inflammation progression, and pulmonary radiology. We investigated in-hospital all-cause mortality (primary endpoint) and renal recovery (secondary endpoint) between the two groups. Results Among the 154 recruited patients, 80 and 74 were in the early and late RRT groups, respectively. There were no significant differences in the demographic characteristics between the two groups. The duration of admission to RRT initiation was significantly shorter in Early RRT group [2.5(1.0, 8.7) d vs. 5.0(1.5,13.5) d, p = 0.027]. At RRT initiation, the patients in the Early RRT group displayed a lower percentage of fluid overload, lower doses of vasoactive agents, higher CRP levels, and higher rates of radiographic progression than those in the Late RRT group. The all-cause in-hospital mortality was significantly lower in the Early RRT group than in Late group (52.5% vs. 86.5%, p < 0.001). Patients in the Early RRT group displayed a significantly higher proportion of complete renal recovery at discharge (40.0% vs. 8.1%, p < 0.001). Conclusion This study clarified that early GDRRT for the treatment of severe pneumonia-associated AKI based on fluid status and inflammation progression, was associated with reduced hospital mortality and better recovery of renal function. Our preliminary study suggests that early initiation of RRT may be an effective approach for severe pneumonia-associated AKI.

Hypoalbuminemia on admission in diabetic patients correlates with severity of illness in COVID-19: A retrospective clinical study and literature review

IntroductionTo elucidate factors associated with severe disease in patients with coronavirus disease 2019 (COVID-19) pneumonia complicated with diabetes mellitus. MethodsAmong patients with COVID-19 pneumonia hospitalized from January to September 2021, 100 patients with diabetes were included in the study. Patients in the intensive care unit admission or in-hospital death category were defined as the severe group (26 patients), and the other patients as the moderate group (74 patients). Comparisons were made between the two groups. Medical histories were extracted from the medical records, and statistical analysis was performed. ResultsPatients were 62.1 ± 13.0 years of age, 70 % male, 48 % aged 65 years and more, and HbA1c was 7.72 ± 1.51 %. The severe group had significantly higher blood glucose level, CRP, WBC, and LDH on admission. Serum albumin level was significantly lower in the severe group and was significantly negatively correlated with number of days on oxygen administration (r = 0.447) and maximal oxygen concentration (r = 0.561). Multiple logistic regression analysis with severity of illness as the objective variable showed that high CRP and low albumin levels on admission, and older age were independently associated. ConclusionsLow albumin levels on admission may be an indicator of severe disease in patients with diabetes.

Histological and Biochemical Alterations Underlying Statin-Associated Pancreatic Toxicity in a Rat Model

ObjectiveTo investigate the histological and biochemical alterations in the pancreas associated with statin-induced toxicity using a rat model. MethodologyA one-year laboratory-based experimental control trial conducted at department of anatomy of a public sector medical college in Rawalpindi, in collaboration with the National Institute of Health (NIH) Islamabad and Armed Forces Institute of Pathology (AFIP) Rawalpindi. Twenty male Sprague-Dawley rats were assigned to the control group and another twenty to the experimental group. For a duration of 12 weeks, the experimental group was given 60 mg/kg/day of simvastatin orally, whereas the control group was given water and a conventional diet. The following characteristics were measured: body weight, pancreatic weight, biochemical parameters (cytokines, enzymes), and histological alterations (congestion, necrosis, fibrosis). Version 23 of the Statistical Package for the Social Sciences (SPSS) program was used to analyze the data. Qualitative variables were expressed as percentages and frequencies. The statistical significance was defined as P &lt; 0.05. Chi-square analyses contrasted the qualitative factors among the groups. ResultsCompared to controls, the simvastatin group showed significantly increased mean pancreatic weight (p=0.043), congestion (55% vs 0%, p&lt;0.001), higher levels of CRP (p&lt;0.030), IL-6 (p&lt;0.040), and TNF-α (p&lt;0.040). Trends of mild necrosis (25% vs 5%, p=0.182) and interstitial fibrosis (15% vs 0%, p=0.231) were observed but not statistically significant. DiscussionThis work shows that simvastatin significantly affects the pancreatic histomorphology and biochemical parameters in rats. It causes a noticeable amount of necrosis, interstitial fibrosis, and changes the pancreatic biochemical profile. These changes raise the possibility of long-term statin-associated pancreatitis and endocrine/exocrine dysfunction. Using a stable animal model, these new findings offer distinctive insights into the impact of simvastatin on pancreatic morphology. Conclusion Simvastatin profoundly impacts pancreatic histomorphology, warranting further investigation into mechanisms of toxicity and close monitoring of patients for pancreatic adverse effects during statin therapy.

Complications and factors associated with mortality in patients undergoing percutaneous endoscopic gastrostomy

Objective: The aim of our study was to examine the factors associated with mortality in patients who underwent percutaneous endoscopic gastrostomy (PEG) and identify biomarkers that may guide clinical practice. Methods: This retrospective observational study included adults who underwent PEG placement in our center. Demographic data, date of PEG placement, inpatient ward, PEG indication, time from admission to PEG placement, post-PEG complications, and outcome (discharge/mortality) were recorded. Logistic regression analysis was performed to identify factors associated with 90-day and 6-month mortality. Results: Of 100 patients included in the study, 52% were men and the median age was 73 years. The most common indication for PEG was malignancy (n=25, 25%). The most common minor complication was minor peristomal bleeding and peristomal infection requiring tube removal The most common major complication was aspiration pneumonia. Thirty-eight patients (38.0%) died within 90 days and 52 patients (52.0%) died within 6 months of PEG placement. The odds of 90-day mortality were 57.5% lower per 1-unit increase in total serum protein level (odds ratio [OR]: 0.425, 95% CI: 0.230–0.888; p=0.021), 1.6% higher per 1-unit increase in serum CRP (OR: 1.016, 95% CI: 1.006–1.027; p=0.003), and 13.6 times higher in patients with aspiration pneumonia (OR: 13.631, 95% CI: 2.997–61.988; p=0.001). For 6-month mortality, a 1-unit increase in serum albumin level was associated with 81.4% lower odds (OR: 0.186, 95% CI; 0.081–0.430; p&lt;0.001) and aspiration pneumonia with 22 times higher odds (OR: 21.984, 95% CI: 2.412–200.342; p=0.006). Conclusion: Aspiration pneumonia, low total serum protein and albumin levels, and high CRP level were associated with higher mortality.

The association of inflammatory markers with frailty and in-hospital mortality in older COVID-19 patients

IntroductionDuring the COVID19 pandemic, older patients hospitalized for COVID-19 exhibited an increased mortality risk compared to younger patients. While ageing is associated with compromised immune responses and frailty, their contributions and interplay remain understudied. This study investigated the association between inflammatory markers and mortality and potential modification by frailty among older patients hospitalized for COVID-19. MethodsData were from three multicenter Dutch cohorts (COVID-OLD, CliniCo, Covid-Predict). Patients were 70 years or older, hospitalized for COVID-19and categorized into three frailty groups: fit (Clinical frailty score (CFS) 1–3), pre-frail (CFS 4–5), and frail (CFS 6–9). Immunological markers (lymphocyte count, neutrophil count, C-reactive protein, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic inflammation index (SII)) were measured at baseline. Associations with in hospital mortality were examined using logistic regression. ResultsA total of 1697 patients were included from COVID-OLD, 656 from Covid-Predict, and 574 from CliniCo. The median age was 79, 77, and 78 years for each cohort. Hospital mortality rates were 33 %, 27 % and 39 % in the three cohorts, respectively. A lower CRP was associated with a higher frailty score in all three cohorts (all p < 0.01). Lymphocyte count, neutrophil count, NLR, PLR, or SII, were similar across frailty groups. Higher CRP levels were associated with increased in-hospital mortality risk across all frailty groups, across all cohorts (OR (95 % CI), 2.88 (2.20–3.78), 3.15 (1.95–5.16), and 3.28 (1.87–5.92)), and frailty did not modify the association between inflammatory markers and in-hospital mortality (all p-interaction>0.05). ConclusionWhile frailty is a significant factor in determining overall outcomes in older patients, our study suggests that the elevated risk of mortality in older patients with frailty compared to fit patients is likely not explained by difference in inflammatory responses.

The clinical utility of handgrip strength as a malnutrition screening tool in hospitalized older adults: a cross-sectional study in Saudi Arabia.

Malnutrition is prevalent among hospitalized older patients. Early identification is therefore essential to implementing appropriate therapeutic interventions. This study aimed to explore the correlation between handgrip strength (HGS) and nutritional status in hospitalized older adults. This observational cross-sectional study was conducted at King Abdulaziz University Hospital, where a consecutive cohort of older adult inpatients was enrolled for participation. Shortly after admission, HGS and nutritional status were assessed using a dynamometer and the most recent version of the Mini-Nutritional Assessment Short Form (MNA-SF) test, respectively. Key anthropometric and biochemical indicators were also collected. A total of 135 consecutive patients were evaluated. Among participants with low HGS, 18 (16.22%) were malnourished, 43 (38.74%) were at risk of malnutrition, and 50 (45.05%) had normal nutrition status. The participants with low HGS had low hemoglobin, low lymphocyte levels, high creatinine levels, high BUN levels, high CRP levels, high HbA1c levels, and high vitamin B12 levels. Multiple logistic regression analysis showed that age, hemoglobin, and HbA1C were independently associated with low HGS. Based on the cut-off values for the HGS by the European Working Group on Sarcopenia in Older People-2 (EWGSOP2), low HGS showed high sensitivity to detect "malnourished and at risk of malnutrition" as well as "malnourished alone;" however, the specificity was low to exclude "malnourished and at risk of malnutrition" as well as "malnutrition alone." Age over 75 years, low hemoglobin, and elevated HbA1C levels were independent risk factors for low HGS. While HGS was sensitive in detecting malnutrition or risk, its specificity was low. Therefore, HGS may not be adequate as a standalone tool to assess nutritional status in hospitalized older adults. Replication of this study using locally reliable and validated HGS cut-off values is warranted to confirm these findings.

Population toxicokinetics of carbamazepine and its metabolite carbamazepine-10,11-epoxide in adults

ABSTRACT Background Carbamazepine is one of the most commonly used antiseizure medications. Although carbamazepine pharmacokinetics in epileptic patients is well described, much less is known about these processes in the patients who experienced self-poisoning episode by this drug. Therefore, the aim of our investigation was to perform population toxicokinetics of carbamazepine and its metabolite carbamazepine-10,11-epoxide in adults. Research design and methods Software program NONMEM and the ADVAN2 TRANS2 subroutine were used for establishing a population toxicokinetic model for the estimation of clearance and volume of distribution based on of the sum values of carbamazepine and carbamazepine-10,11-epoxide concentrations. Results Our results indicated that the adult patients’ ability to eliminate carbamazepine and carbamazepine-10,11-epoxide following acute carbamazepine self-poisoning was strongly associated with the high levels of CRP and ASP, as well as by the treatment with sedation. Conclusions Our study should provide better understanding of the toxicokinetics of carbamazepine taken in overdose and better management of patient population admitted to hospital.

High C-Reactive Protein Serum Levels as a Risk Factor for Preeclampsia

Introduction: Preeclampsia is a hypertensive syndrome in pregnancy characterized by increased blood pressure, proteinuria, and complications such as liver dysfunction and visual impairment. This condition is associated with an inflammatory reaction and failure of trophoblast invasion of maternal arteries, which involves an increase in proinflammatory cytokines that indirectly induce CRP production. However, data showing the value of CRP levels as an indicator of the incidence of preeclampsia in Indonesia is minimal. This study aims to evaluate CRP levels as a predictor of preeclampsia.Methods: This case-control study involved pregnant women with preeclampsia and normal pregnant women who went to the Obstetric Emergency Installation at Prof. Hospital. Dr. I.G.N.G Ngoerah Denpasar. All data were obtained from patient medical records and then analyzed using the SPSS v.22.Results: This study involved 56 pregnant women consisting of 28 normotensive pregnant women (control) and 28 pregnant women with preeclampsia (cases) at Prof. Dr. I.G.N.G. Ngoerah General Hospital Denpasar from January to December 2023. The median age was 27.5 years (control) and 26.0 years (cases), with an age range of 18–40 years. The median BMI WAS 21.65 kg/m2 (controls) and 21.80 kg/m2 (cases). Most patients in both groups were nulliparous (50.0%, controls; 42.9%, cases). Based on ROC analysis, the CRP cut-off value of 7.76 mg/dL has a sensitivity of 76.7%, specificity of 78.6%, and an area under the curve (AUC) of 0.737, where pregnant women with high CRP (≥7.76 mg/dL) had a 12.048-fold higher risk (95%CI 3.496–41.515; p &lt; 0.001) of experiencing preeclampsia compared to pregnant women with low CRP levels.Conclusion: High serum CRP levels are a risk factor for preeclampsia. These findings indicate that measuring CRP levels can be a potential tool for identifying the risk of preeclampsia in the pregnant population.

Sequential Impact of Diabetes Mellitus on Deep Neck Infections: Comparison of the Clinical Characteristics of Patients with and without Diabetes Mellitus.

Deep neck infections (DNIs) can compromise the airway and are associated with high morbidity and mortality rates. Diabetes mellitus (DM) is a metabolic disorder characterized by chronic hyperglycemia that is associated with several comorbidities. We compared the clinical characteristics of DNI patients with and without DM. This study recorded the relevant clinical variables of 383 patients with DNIs between November 2016 and September 2022; of those patients, 147 (38.38%) had DM. The clinical factors between DNI patients with and without DM were assessed. Patients with DM were older (p < 0.001), had higher white blood cell counts (p = 0.029) and C-reactive protein levels (CRP, p < 0.001), had a greater number of deep neck spaces (p = 0.002) compared to patients without DM, and had longer hospital stays (p < 0.001). Klebsiella pneumoniae was cultured more frequently from patients with DM than those without DM (p = 0.002). A higher CRP level (OR = 1.0094, 95% CI: 1.0047-1.0142, p < 0.001) was a significant independent risk factor for DM patients with prolonged hospitalization. The lengths of hospital stays in patients with poorly controlled DM were longer than those with well-controlled DM (p = 0.027). DNI disease severity and outcomes were worse in patients with DM than those without DM. Antibiotics effective against Klebsiella pneumoniae should be used for DNI patients with DM. DNI patients with DM and high CRP levels had more prolonged hospitalizations. Appropriate blood glucose control is essential for DNI patients with DM.

The Relationship between the Laboratory Biomarkers of SARS-CoV-2 Patients with Type 2 Diabetes at Discharge and the Severity of the Viral Pathology.

In this study, we evaluated the discharge status of patients with type 2 diabetes mellitus and SARS-CoV-2 infection, focusing on the inflammatory profile through biomarkers such as procalcitonin, CRP, LDH, fibrinogen, ESR, and ferritin, as well as electrolyte levels and the prior diagnosis of diabetes or its identification at the time of hospitalization. We assessed parameters at discharge for 45 patients admitted to the Clinical Hospital "Gavril Curteanu" Oradea between 21 October 2021, and 31 December 2021, randomly selected, having as the main inclusion criteria the positive RT-PCR rapid antigen test for viral infection and the diagnosis of type 2 diabetes. At discharge, patients with type 2 diabetes registered significantly lower mean procalcitonin levels among those who survived compared to those who died from COVID-19. In our study, ferritin and hemoglobin values in individuals with type 2 diabetes were outside the reference range at discharge and correlated with severe or moderate forms of COVID-19 infection. Additionally, elevated ferritin levels at discharge were statistically associated with hypokalemia and elevated levels of ESR at discharge. Another strong statistically significant correlation was identified between high CRP levels at discharge, strongly associated (p < 0.001) with elevated LDH and fibrinogen levels in patients with type 2 diabetes and SARS-CoV-2 viral infection. The increase in CRP was inversely statistically associated with the tendency of serum potassium to decrease at discharge in patients with type 2 diabetes and COVID-19. Identifying type 2 diabetes metabolic pathology at the time of hospitalization for SARS-CoV-2 infection, compared to pre-infection diabetes diagnosis, did not significantly influence the laboratory parameter status at the time of discharge. At the discharge of patients with type 2 diabetes and viral infection with the novel coronavirus, procalcitonin was significantly reduced in those who survived COVID-19 infection, and disease severity was significantly correlated with hyperferritinemia and decreased hemoglobin at discharge. Hyperferritinemia in patients with type 2 diabetes and COVID-19 at discharge was associated with hypokalemia and persistent inflammation (quantified by ESR at discharge). The low number of erythrocytes at discharge is associated with maintaining inflammation at discharge (quantified by the ESR value).
