Significance of Initial Chest CT Severity Score (CTSS) and Patient Characteristics in Predicting Outcomes in Hospitalized COVID-19 Patients: A Single Center Study

The aim of this study is to examine the prognostic role of initial chest computed tomography severity score index (CTSS) and its association with demographic, socio-epidemiological, and clinical parameters in COVID-19 hospitalized patients. A retrospective study included patients who were hospitalized in the COVID Hospital of the Clinical Hospital Center Kosovska Mitrovica from July 2020 to March 2022. We compared patient characteristics and outcome of their hospital stay with values of CT severity score (mild, moderate, and severe form of the disease). Patients with severe disease were statistically significantly older, they treated more days, and they presented statistically significant highest mortality rate compared to mild and moderate forms. Smokers and obese were significantly more frequent among patients with higher CT, while vaccinated patients were more common among those with a mild form. Biochemical parameters at admission also showed statistical significance between the examined groups. We can conclude that by employing the initial CT severity score as the strongest predictor of mortality, it is possible to predict the outcome in hospitalized patients. A comprehensive examination of the patient upon admission, including determining the extent of inflammatory changes in the lungs using computed tomography, the levels of oxygen saturation, and other laboratory parameters, can assist doctors in making an adequate clinical evaluation and apply appropriate therapeutic protocols in the treatment of COVID-19.

Development of a triplex endpoint PCR assay for the detection of SARS-CoV-2: insights on cost-efficiency and method design.

Lower respiratory tract infections, including COVID-19, have a substantial global impact, making the development of diagnostic tests crucial. The study aimed to develop a new, accurate, fast, and cost-effective PCR-based detection method for SARS-CoV-2, applicable in limited settings and capable of detecting all current variants and potential future pathogens. The study was conducted between 2020 and 2022 at the molecular biology department of Mures County Clinical Hospital, Romania. Initially, pharyngeal and nasal secretions were collected and processed using the real-time qRT-PCR method for routine COVID-19 diagnosis. Ninety-two samples were randomly selected to develop the assay, including samples from different infection periods and negative controls. Complementary DNA (cDNA) was prepared from the selected samples, and the presence and integrity of the extracted RNA were evaluated by amplifying the GAPDH housekeeping gene. Primers for three specific viral genes (N, ORF1ab, and S) were designed, and their efficiency was evaluated using endpoint PCR and sequencing. Finally, the method was optimized and implemented as a one-step triplex PCR assay for routine diagnostic use. The molecular laboratory at the Mures County Clinical Hospital (MCCH) analyzed a total of 41,818 samples between June 2020 and December 2022. Among these samples, 26.15% tested positive for SARS-CoV-2, while 70.9% were negative and 2.95% were inconclusive or invalid. Three peaks of positive tests were observed in November 2020, April 2021, and February 2022. The study selected 92 preserved RNA samples for triplex-PCR assay development, validating the primers' specificity and confirming the quality of the nucleic acids. The comparative analysis showed the efficiency and accuracy of the endpoint reverse-transcription triplex-PCR method (RT-PCR), indicating its potential as a cost-effective alternative to real-time reverse-transcription PCR (qRT-PCR) in low-income countries with limited infrastructure for COVID-19 testing. This method has the potential to facilitate large-scale diagnosis of SARS-CoV-2 infections, allowing for rapid and appropriate therapeutic management and ongoing monitoring of patients. Additionally, the method can be easily adapted for the detection of other pathogens.

Relevance of Thyroid Microcarcinoma and Its Diagnosis

Microcarcinoma is a thyroid gland cancer with a size of less than 1 cm. The aim: To determine the frequency of microcarcinoma among malignant pathologies of the thyroid gland based on fine-needle aspiration biopsies (FNAB) data. Materials and Methods: A retrospective analysis of 2490 FNAB data was conducted under ultrasound control from 2007 to 01.07. 2024 at the Ternopil Regional Clinical Hospital. FNAB results were categorized into four groups: the first group – non-diagnostic results, the second – suspicion of thyroid cancer, the third – thyroid cancer, and the fourth – benign lesions. After the Bethesda system was introduced, FNAB classifications were based on this system. Results: Thyroid cancer was diagnosed in 186 cases (7.5%). Among these, macrocarcinoma was identified in 152 cases (81.7%) and microcarcinoma in 34 cases (18.3%). The peak incidence of microcarcinoma is observed in the 40-50 age, with approximately 90% of patients being women. Microcarcinomas in solitary nodules were found in 16 cases (47%); among multinodular goiters in 18 cases (53%). In 8 cases (23.5%), microcarcinoma was associated with larger thyroid cancers (multifocal process) and in 4 cases (11.8%) with benign nodules. In 6 cases (17.7%), microcarcinomas were associated with nodules suspicious for cancer. Conclusions: Indications for FNAB should be guided by the identified sonographic characteristics (solid echostructure of the nodule; hypoechogenicity; vertical orientation of nodules; indistinct margins of the nodule; presence of microcalcifications; regional cervical lymphadenopathy with signs of malignancy).

Assessing the impact of a dedicated referral and management algorithm in maternal hypothyroidism.

The significant risks of hypothyroidism during pregnancy can be mitigated through timely diagnosis and initiation of thyroxine to achieve a maternal euthyroid state. This study aimed to evaluate the efficiency of hospital endocrine services by assessing the rate of thyroxine commencement before the initial clinic appointment, the median gestational age at the first consultation, the rate of guideline-appropriate investigations, perinatal outcomes, and the proportion of referred patients who achieved their target thyroid-stimulating hormone (TSH) levels before and after implementing a dedicated referral and management pathway. A retrospective clinical audit was conducted using electronic medical records for the first fifty consecutive patients with hypothyroidism referred to the hospital clinic during two-time intervals: from April 1 to September 1, 2020 (pre-intervention) and from April 1 to September 1, 2021 (postintervention). Following the pathway implementation, there was no significant difference in the proportion of women with initially raised TSH who were prescribed thyroxine prior to the first clinic appointment (P=0.83). However, the first TSH measurement occurred earlier (median 5.5 vs. 6.5 weeks, P=0.011), and specialist reviews were conducted sooner (median 19 vs. 22 weeks, P=0.032). Significantly more women with elevated TSH underwent thyroid autoantibody testing postintervention (78% vs. 55.5%, P=0.035). There was no significant difference in perinatal outcomes. All women achieved their target TSH levels, with a median final TSH of 1.6 mIU/L (IQR: 1.2 to 2.3). While the proportion of referred patients achieving target TSH levels during pregnancy remained unchanged, certain measures of service efficiency improved. These included earlier TSH measurement, earlier endocrinologist review, and increased detection of thyroid autoantibodies.

No reimbursement policy and implantable loop recorders in the real world setting

Abstract Background Prolonged heart rhythm evaluation is indicated in patients with suspected arrhythmias. Routine electrocardiographic Holter monitoring is often associated with poor adherence and may lead to little to no clinically relevant findings. Implantable loop recorders (ILRs) are small, subcutaneous cardiac devices providing semi-continuous electrocardiographic recording. Despite strong evidence supporting their effectiveness, ILRs are yet to be fully reimbursed by the National Health Fund- the public insurer in Poland. Purpose We aimed to investigate the feasibility, as well as the diagnostic yield of ILRs in a real world setting of a tertiary cardiovascular center. Methods We retrospectively analyzed data of consecutive patients admitted for ILR implantation between March 2013 nad November 2023. Hospitalization and procedural costs were covered by the clinic's statutory and hospital funds and not by the National Health Fund, the public payer. All patients were remotely monitored for device follow-up. Baseline demographic characteristics, as well as data regarding observation period, clinical outcomes and safety were collected. Results Data for 51 ILR implants in 50 patients was assessed. Insertion success rate was 100% on first attempt with no complications. Mean age was 54,43 ±18,56 years old. 52,94% of patients were female. Coronary artery disease was present in 21,57% patients, hypertension in 50,98%, diabetes in 13,73%. The indications for ILR implantation were unexplained syncope (n= 42; 82,35%), palpitations (n= 16; 31,37%), ischemic stroke of unknown origin (n= 6; 11,76%), monitoring of ventricular arrhythmia (n= 2; 3,92%). Mean time between occurrence of first symptoms and ILR implantation was 80,86 ±112,95 months. Mean monitoring period was 1067,62 ±668,89 days. 23 (45,1%) patients had an actionable event detected. Mean time to clinical outcome was 190,34 ±514,85 days. Based on the obtained recordings, in 13 (25,49%) patients a cardiac electronic device was implanted and 6 (11,76%) underwent an electrophysiological procedure. Time to intervention was 435,17 ± 542,9 days and 338,8 ± 273,44 days, respectively. ILR prompted medication modification in 14 (27,45%) patients. Antiarrhythmic drugs were modified in 6 (11,76%) patients. Oral anticoagulation was initiated in 3 (5,88%) patients. Mean time to any pharmacotherapy modification was 654,68 ± 604,32 days. Skin infections occurred in 2 patients, leading to early device removal. Conclusions This is the first study to present a comprehensive evaluation of ILR patients in Poland, along with a substantial observation period. We report a high prevalence of treatable cardiac conditions in patients with previous unsuccessful diagnostic work up. In the light of the upcoming favourable changes in governmental healthcare policy, demonstrating evidence supporting ILR application in everyday clinical practice is crucial for advocating their wider utilization and reimbursement.

Correlation between vaccine hesitancy, vaccine reliability and perceptions of infectious diseases

Abstract Background Vaccine hesitancy is a delay in vaccine acceptance or refusal despite the availability of vaccination services. In recent years, the rise in vaccine hesitancy has attracted attention. This study aimed to evaluate the perception of vaccine hesitancy, vaccine safety, and infectious diseases among parents. Methods This cross-sectional study was conducted with 503 parents who applied to the pediatrics outpatient clinic of a university hospital. The questionnaire used in the study included questions on sociodemographic characteristics, factors related to vaccine hesitancy, The Vaccine Hesitancy Scale (VAS), the Vaccine Safety Scale (VSS), and the Perception Scale for Infectious Diseases (PPSID). Multivariate Linear Regression Analysis was used to find the variables associated with vaccine hesitancy. Results The mean age of the parents was 37.6±7.6 years. Parents’ scores on the ATS ranged from 17-85, with a mean score of 20.1±6.6 points. A moderate negative correlation was found between parents’ VAS and VSS scores, and between VAS and PPSID scores (r=-0.412, p < 0.001; r=-0.409, p < 0.001, respectively). According to the multivariate linear regression analysis the variables found to be associated with vaccine hesitancy, income status, maternal education level, child’s age group, having information about childhood vaccination schedule, child’s immunization status, the necessity of childhood vaccines, having sufficient information about the safety of vaccines, vaccine safety level, and infectious disease perception level were found to be significant predictors of vaccine hesitancy (F: 12,844, p ≤ 0.001, R2: 0.334). Conclusions This study determined that vaccine hesitancy was higher in families with lower income, who have not completed the schedule nor been vaccinated, doubt the necessity of vaccines to prevent infectious diseases, lack of knowledge about the reliability of vaccines, and whose children are still in primary school. Key messages • Health professionals have a critical role in reducing vaccine hesitancy. • It would be appropriate to plan face-to-face or online programs with parents.

Genotype-phenotype correlation of transthyretin cardiomyopathy in patients with stage C/D heart failure: atrial and myocardial mechanics and fibrosis

Abstract Objectives We sought to investigate: (1) the relationship between transthyretin (TTR) pathogenic variants and their corresponding echocardiographic atrial and ventricular strains in patients with TTR cardiomyopathy (TTR-CM) and clinical evidence of heart failure (HF), and (2) the relationship between TTR pathogenic variants and atrial fibrosis assessed by cardiac MRI. Methods and results Fifty Asian patients with biopsy or scintigraphy proven TTR-CM and stage C or D (C/D) HF were identified from an advanced HF clinic in a tertiary-care university hospital. Genetic testing for the pathogenic variants in the TTR genes associated with hereditary TTR-CM (hTTR-CM) was available in 22 patients (67 ±13 years; 77% were male). Of these, 3 different mutations were identified. The most prevalent pathogenic variant was Ala97Ser (67%) followed by Val30Met (27%), and Gly67Glu (6%). Wild-type TTR-CM was diagnosed in 32% of the cohort. Strain analysis was performed using the TomTec Arena 2D-cardiac performance analysis (CPA) software. Atrial and left ventricular (LV) late gadolinium enhancement (LGE) was quantified using a 9-segment and a 17-segment model, respectively. Patients with hTTR-CM had less impaired longitudinal strain (LS) (more negative strain values) than those with wild-type TTR-CM in the regional basal right ventricular free wall (RV-FW) (-21 ± -8.3 % vs.-12.6 ± -8.1%, p = 0.048) and LV basal inferoseptum (-7.3 ± -4.1 % vs.-3.1 ± -3.0 %, p = 0.045). In univariate analysis, more negative LS values in the basal LV inferoseptum and basal RV-FW were significant predictors of hTTR-CM (OR 5.1 and 2.3; p <0.05, respectively). However, MRI findings revealed similar regional LGE extent involving basal inferolateral segments between hTTR-CM and wild-type TTR-CM (38.3 ± 7.9 vs. 52.5 ± 34.5%, p =0.314). Left atrial (LA) and right atrial (RA) LGE was present in 90% and 81% of patients, respectively. Patients with hTTR-CM had reduced RA LGE when compared to those with wild-type TTR-CM (41% vs 67%, p =0.039). Conclusions In patients with TTR-CM and stage C/D HF, a reduced RA LGE extent and/or more preserved myocardial deformation in specific regions of basal LV and RV segments (basal LV inferoseptum and basal RV free wall) assessed by 2-D speckle tracking echocardiography were significantly more prevalent in patients with hTTR-CM than in wild-type TTR-CM. These echocardiographic and/or MRI findings may facilitate genotype testing in patients with TTR-CM, particularly in resource-limited settings. Further validation of these novel findings in patients with TTR-CM with HF is needed.

Adaptive Hyperactivity and Biomarker Exploration: Insights from Elders in the Blue Zone of Sardinia

Background/Objectives: Adaptive hyperactivity characterized by increased activity levels and novelty-seeking traits without mood disorders is prevalent among older adults in Sardinia’s “blue zone,” an area with high longevity. This study aims to evaluate the adaptive nature of hyperactivity concerning quality of life, social rhythms, and mood symptoms in individuals from this region, particularly among elderly adults over 80. Methods: This observational cross-sectional study included adults and older adults over 80 from Sardinia’s blue zone. This study included a sample of patients followed at the Center for Consultation Psychiatry and Psychosomatics for Bipolar Disorder of the University Hospital of Cagliari and a homogeneous comparison sample of patients without psychiatric pathologies, referred to the Dermatology Clinic of the same hospital, for a period of 6 months, from February to August 2024. The general sample, divided into two parts—cases, represented by patients with psychiatric pathology, and controls, patients without psychiatric pathology—was divided in turn into three sub-groups: “adults” (18–64 years), young elders (65–79), and old elders (over 80 years). The participants underwent psychiatric interviews and completed the Mood Disorder Questionnaire (MDQ), Patient Health Questionnaire (PHQ-9), SF-12, and Brief Social Rhythm Scale (BSRS). Data were compared with national and regional normative data. Results: Older adults in the blue zone demonstrated higher MDQ positivity (22.58%) compared to the national averages (0.87%), without corresponding increases in dysregulated rhythms, depressive symptoms, or reduced quality of life. Younger old persons (65–79 years) showed increased rhythm dysregulation (BSRS score: 20.64 ± 7.02) compared to adults (17.40 ± 6.09, p = 0.040), but this trend was not observed in the oldest group (80+ years). No significant differences were found in the CH3SH and (CH3)2S levels between groups. Conclusions: The hyperactivity observed in older adults from Sardinia’s blue zone appears adaptive and not linked to social rhythm dysregulation, depressive symptoms, or a diminished quality of life, suggesting resilience factors which may contribute to longevity. These findings support the potential classification of such hyperactivity as beneficial rather than pathological, warranting further research into biomarkers and psychoeducational interventions to prevent the onset of bipolar disorders in predisposed individuals.

Patient characteristics and incidence of cardiac amyloidosis: an observational study in the UK clinical setting using electronic health records

Abstract Background Cardiac amyloidosis (CA) is associated with a high mortality rate due to sudden or progressive heart failure. It is often misdiagnosed due to non-specific symptoms, and its true incidence and prevalence in the United Kingdom (UK) remain uncertain. Purpose To describe patient characteristics and incidence of CA in the UK clinical setting using electronic health records. Methods In this retrospective observational study, anonymised, linked primary and secondary care data (Clinical Practice Research Datalink, CPRD and Hospital Episode Statistics, HES) were used to describe individuals diagnosed with CA. The CPRD database contains de-identified patient data sourced from a sample of general practitioner (GP) practices in the UK. Patients aged 18 years and older with a recorded Read or SNOMED-CT diagnosis code for CA or record of treatment with tafamidis (a licensed but not reimbursed treatment for transthyretin amyloid cardiomyopathy, ATTR-CM in the UK) in the period between January 2004 to December 2021 were included. The index date was defined as the earliest recorded date of CA diagnosis or tafamidis treatment. Demographic and clinical data were summarised using descriptive statistics. Incidence rates were reported per 100,000 person-years (PY). Results There were a total of 3,788 patients with CA (mean age: 67 years; 61% males) of which only 277 were coded as having wild-type transthyretin (ATTRwt) CA in mostly older patients (mean age: 79 years). The low patient counts of ATTRwt amyloidosis could be attributed to the lack of specificity in CA types and the low utilisation of ATTR amyloidosis codes. Heart Failure, essential hypertension and dyspnoea were the most common clinical presentations recorded in the 12 months to first diagnosis code or tafamidis prescription for CA (Table). The incidence of CA varied from 0.75 in 2004 to a peak of 1.96 in 2021, per 100,000 PY; a 2.9-fold increase in newly coded diagnoses in CA. There was a slight decline in the rates in 2020 and 2021 (Figure). Incidence rates in males and females increased over the 17-year period, with males consistently having higher rates than females. The incidence rate in females started from a lower base at 0.62/100,000 PY in 2004, increased by a factor of 1.9 to 1.1/100,000 PY, whereas in males it started at 0.88/100,000 PY and rose by a factor of 2.9 to 2.5 /100,000 PY. Incidence rates in subgroup populations have also been analysed. Conclusions In the UK clinical setting, the incidence rate of newly coded CA increased overall between 2004 and 2021, as well as in both male and female subgroups. The data suggest CA is becoming more common, or that awareness has improved, and there is now an urgent need for enhanced methods of detection, characterisation, and the need for thorough data capture to shape future pathway advancements.

Relationship between chronic obstructive pulmonary disease and heart failure hospitalization in patients with atrial fibrillation: the Fushimi AF Registry

Abstract Background Chronic heart failure and chronic obstructive pulmonary disease (COPD) are both common diseases and often co-exist. Patients with COPD are at increased risk for hospitalizations due to cardiovascular diseases. However, in patients with atrial fibrillation (AF), the relationship between COPD and the risk of heart failure (HF) hospitalization remains unclear. Purpose The purpose of this study was to investigate the relationship between COPD and HF hospitalization in AF patients. Methods The Fushimi AF Registry, a community-based prospective survey, was designed to enroll all of the AF patients in Fushimi-ku, Japan. Fushimi-ku is densely populated with a total population of 283,000 and is assumed to represent a typical urban community in Japan. We started to enroll patients from March 2011, and follow-up data were available for 4,496 patients by the end of February 2022. We compared patients with and without COPD with regard to clinical background and HF hospitalization during follow-up period. Results In this cohort, the proportion of pre-existing HF among patients with COPD was 30.1%, and the proportion of COPD among patients with pre-existing HF was 5.9%. Of 4,496 patients, 238 (5.3%) patients had COPD (COPD; the mean age 75.6 years, female 20.6%), and the remaining 4,258 patients did not (Non-COPD; the mean age 73.5 years, female 41.6%). Patients with COPD were older than those without COPD. However, the proportions of patients with pre-existing HF, previous stroke, vascular disease, cardiomyopathy, coronary artery disease (CAD), diuretic use, renal dysfunction, diabetes mellitus (DM) and hypertension were comparable. During the median follow-up period of 1,824 days, the incidence of HF hospitalization was significantly higher in COPD than in Non-COPD (COPD vs. Non-COPD; 4.85% vs. 3.01% per person-year: p<0.01). In multivariate analysis adjusted by sex, age (≥ 75 years), heart disease (combined by heart failure, vascular disease, cardiomyopathy and CAD), renal dysfunction, DM, hypertension and diuretic use, COPD was an independent risk factor for HF hospitalization (hazard ratio (HR) 1.54, 95% confidence interval (CI) 1.15-2.07, P<0.01) (Figure 1). When we analyzed patients without pre-existing HF, the incidence of HF hospitalization was also significantly higher in COPD than in Non-COPD (COPD vs. Non-COPD; 2.87% vs. 1.75% per person-year: p=0.02). In multivariate analysis after adjusting for the same factors, COPD was an independent risk factor for HF hospitalization (HR 1.63, 95% CI 1.05-2.53, P=0.03) (Figure 2). Conclusion In patients with AF, COPD was the risk of HF hospitalization. The results were consistent in AF patients without pre-existing HF.

Extrapulmonary tuberculosis - surgeons' experience at a district hospital: a study of 84 cases

Background: Managing extrapulmonary tuberculosis (EPTB) is challenging due to the non-specific signs and symptoms, the low sensitivity of diagnostic tests, and the potential for the disease to mimic other conditions. The aim of the study was to evaluate the clinical characteristics, surgical management, and outcomes of extrapulmonary tuberculosis at a district hospital, based on an analysis of 84 cases. Methods: This prospective study was conducted at the Department of Surgery in collaboration with the Department of Medicine at Magura District Hospital and private clinics of Magura District, Magura, Bangladesh, from January 1, 2013, to December 31, 2018, including 84 patients diagnosed with extrapulmonary tuberculosis. Informed consent was obtained from all participants or their guardians, and data on demographics, clinical presentation, diagnostic tests, and treatment outcomes were analyzed using SPSS version 20. Results: The study showed that 33 (39.29%) patients were aged 21-30 years, with a majority being female 49 (58.33%) and from rural areas 46 (54.76%). All patients had a palpable mass, with the cervical lymph nodes most affected 78 (92.86%). Lymph node tuberculosis was the most common site 55 (65.48%) and chest radiography was negative for tuberculosis in 81 (96.43%) patients. Treatment was medical only for 41 (48.81%) patients and combined medical and surgical for 43 (51.19%) patients. Conclusions: Extrapulmonary tuberculosis, particularly cervical lymph node involvement, remains prevalent in rural, low socio-economic populations, underscoring the importance of comprehensive diagnostic and treatment approaches.

Hemato-oncology services and COVID-19 Pandemic: The experience of Kazakhstan

Abstract Objectives The COVID-19 pandemic in Kazakhstan disrupted numerous healthcare services, including those critical for hemato-oncology patients, due to the strained healthcare system. This study examines how the COVID-19 pandemic has affected access to hemato-oncology healthcare services in Almaty, Kazakhstan. Methods We retrospectively analyzed patient data from two tertiary centers, City Clinical Hospital 7 (H7) and Kazakh Institute of Oncology and Radiology (KazIOR), from March 1, 2019, to February 28, 2022. Variables included age, gender, residence, hospitalization rate, treatment outcomes (discharged/deceased/transferred), diagnoses (acute leukemia, lymphoproliferative diseases, myeloproliferative diseases), and referral sources. The Statistical Yearbook of Kazakhstan provided comparative data. Results From 2019-2022, 6,763 hemato-oncology hospitalizations were registered: 3,583 in H7 and 3,180 in KazIOR. The mean age was 55.04 (SD = 16.07) for females and 51.2 (SD = 16.7) for males. Urban and rural patient proportions were 6,191 (92%) and 571 (8.4%), respectively (Chi-square 13.8, P = 0.001). Fewer patients were discharged in 2020-2021 (n = 2,047) compared to 2019-2020 (n = 2,387) and 2021-2022 (n = 2,081) (Chi-square 20.09, P = 0.003). The death rate was higher in 2020-2021 (3.5%) than in 2019-2020 (3.2%) and 2021-2022 (2.6%) (Chi-square 20.09, P = 0.003). Emergency admissions were 403 (19%) in 2020-2021, 368 (14.8%) in 2019-2020, and 394 (18.3%) in 2021-2022 (Chi-square 2,231, P < 0.001). Transfers from other hospitals increased by 12.4% in 2020-2021. Conclusions The COVID-19 pandemic negatively impacted access to hemato-oncology services, increasing mortality. Further studies are needed to understand the factors affecting hospitalization and mortality trends during healthcare crises. Funding: Grant No. AP09260497. Key messages • Access to healthcare services during COVID-19 pandemic for hemato-oncology patients. • Impact of the pandemic on access to healthcare.

Increased miRNA-related inflammation markers and pro-inflammatory circulating cell profile in patients with poor neurological outcome after out-of-hospital cardiac arrest

Abstract Background Out-of-Hospital Cardiac Arrest (OHCA) supposes a main cause of disability and mortality worldwide. Between patients suffering OHCA, only a 10-20% can be successfully resuscitated and, between them, a 50% suffers of neurological sequelae. Mechanisms underlying brain damage seems to be strongly related with neuroinflammation, mediated by classical (PCR, NLR) and novel (miRNAs) agents at play. Even there are studies suggesting the relevance of miRNA-mediated inflammatory response in ECA, no consistent conclusions about its role in ECA outcomes have been obtained. Purpose The aim of the present investigation is to study the temporal patterns of classical (PCR, NLR) and novel (miRNAs) inflammation markers during hospitalization of ECA patients and to correlate them with neurological outcome. Methods Consecutive OHCA patients were prospectively recruited at the Acute Cardiac Care Unit (ACCU) of the hospital Clinic of Barcelona from March 2019 to December 2023. Serum samples were obtained at 0, 24 and 72 hours after hospital admission. Patients were grouped according to their neurological outcome, measured by Cerebral Performance Category (CPC), at hospital discharge. Classical inflammation markers (PCR and NLR) were measured and in silico pre-targeted serum circulating-miRNAs were analysed by qPCR. Results A total of 120 patients (60 ± 13 years, 20% female) were included for the analysis. At hospital discharge, 55 (45%) patients survived with good NO (GNO; CPC 1-2) and 65 (55%) patients presented a poor NO (PNO; CPC 3-5). Classical inflammation markers such as PCR and NLR were significant higher in PNO than in GNO Group (P-value = 0.0042 and p-ANOVA = 0.0444, respectively) (Figure 1A). 11 inflammation-related miRNAs with strong correlation with OHCA-related conditions such as cardiovascular and coronary artery disease, hypoxic encephalopathy and neuro-inflammation were pre-targeted by in silico analysis. Five of the pre-targetedmiRNAs (miR-21-5p, miR-23a-3p, miR-146-5p, miR-155-5p and miR-181a-5p) presented significant differences between GNO and PNO groups (p-ANOVA = 0.0001, 0.0027, 0.0001, 0.0023 and 0.0002 respectively) in at least one time point, with an reduced expression in all cases in the PNO respect the GNO group (Figure 1B). Conclusions Patients with PNO after OHCA presents a downregulation of inflammation-regulatory miRNAs that leads an increase of clinical inflammation-related mediators such as PCR and NLR, with potential neuro-inflammatory consequences.

Clinical trial protocol for continuous glucose monitoring in critical care at Hospital Clinic of Barcelona (CGM-UCI23).

Hyperglycaemia is common in intensive care units (ICUs), with a prevalence of up to 86.2%, increasing mortality. Technology has evolved towards continuous glucose monitoring (CGM), and its use in ICUs began especially during the coronavirus pandemic (COVID-19). Various studies have evaluated the reliability of CGM, indicating that it is safe for use in critically ill patients. The aim of this study was to compare the use of CGM with point-of-care glucose (POC-G) testing in ICU. Specific objectives include evaluating the glycaemic control, the frequency of POC-G measurements, the incidence of hyperglycaemia, hypoglycaemia and morbidity and mortality at 90 days. An experimental, controlled and randomized clinical trial with a single-blind design will be conducted at Hospital Clinic of Barcelona (HCB). A sample size of 376 participants will be recruited and randomly assigned to two groups: an experimental group, where glycaemic management will be based on CGM; and a control group, where glucose will be managed through POC-G testing, with a blinded CGM. The primary variable considered will be time in range (TIR), with secondary outcomes including, time above range (TAR), time below range (TBR), number of POC-G measurements, incidence of hyperglycaemia and hypoglycaemia, and mortality. Hypothesis testing will use the Kolmogorov-Smirnov test to assess data normality, with appropriate statistical tests applied, considering a p-value <.05. The results obtained will help us understand the impact of CGM on critically ill patients. CGM could potentially reduce the workload of nurses and improve the efficiency of decision-making by the ICU team, enabling early identification and treatment of glucose complications, thereby enhancing safety. Patient safety, a reduction in patient fingerstick and a decreased care burden are the criteria that add value to this research.

Evaluation of Pharmaco-invasive PCI in Terms of in Hospital Clinical Outcome of Acute Anterior ST Segment Elevation Myocardial Infarction Patients Compared to Primary PCI

Background: The strategic reperfusion early after Myocardial Infarction trial and the French Registry of Acute Anterior ST segment elevation MI suggested that pharmaco-invasive strategy compares favorably with primary percutaneous coronary intervention (PPCI). Objectives: To evaluate in hospital clinical outcome of patients with acute anterior ST segment elevation myocardial infarction undergoing Primary PCI and pharmaco-invasive PCI. Methods: This cross sectional study was conducted in United Hospital, Dhaka. A total of 120 patients were studied. These patients were categorized into two groups. Those with acute anterior ST segment elevation MI who underwent primary PCI was denoted as group A (n= 55) and those with acute anterior ST segment elevation thrombolysed by streptokinase followed by PCI confined to pharmaco-invasive PCI was denoted as group B (n=65). Results: Acute LVF was more in pharmaco-invasive group than in primary PCI group and was statistically significant (p= 0.032). 02 patients (3.6%) died in primary PCI group: one of which was due to ventricular fibrillation followed by asystole 3 hours after procedure and the other died due to cardiac arrest 10 hours after the procedure. No major bleeding incidence was found in both groups. Conclusion: Acute anterior ST segment elevation myocardial infarction patients receiving pharmaco-invasive treatment compared with the Primary PCI had higher incidence of acute LVF and no significant discrepancy was observed regarding bleeding events, death, stent thrombosis, arrythymia, heart block and cardiac arrest.

Impact of Home-Based Rehabilitation on Renal Prognosis in Patients with Chronic Kidney Disease.

The increasing prevalence of chronic kidney disease (CKD) requires effective preventive measures, particularly due to an aging population. This study aimed to assess the effectiveness of home visit rehabilitation in preventing renal function decline among patients with CKD. In this retrospective study, patients with non-dialysis CKD undergoing home visit rehabilitation were compared with those receiving outpatient care at the Nippon Medical School Hospital between August 2017 and August 2023. Patients' backgrounds were matched using propensity scores derived from a logistic regression model. The primary endpoint was the annual change in the estimated glomerular filtration rate (eGFR), and the secondary endpoint was the annual change in blood parameters (Δblood urea nitrogen, Δcreatinine, Δtotal protein, Δalbumin, ΔC-reactive protein, Δhemoglobin, and Δhematocrit). Furthermore, the incidence of clinical outcomes, including mortality, hospitalization rate, and dialysis initiation rate, were analyzed within the additional 1-year observation period. Overall, 128 patients (64 matched pairs) were analyzed. After a mean follow-up period of 12.7 ± 4.6 months, there was no significant difference in the eGFR between both groups (40.1 ± 13.7 vs. 37.8 ± 13.8 mL/min/1.73 m2, p = 0.36), but the annual decline in eGFR (%/year) was significantly lower in the rehabilitation group (-1.1 ± 29.8% vs. -11.8 ± 27.7%/year, p = 0.037). The annual change in the level of each blood test parameter and clinical outcomes were not significantly different between the two groups. Home-based rehabilitation interventions may mitigate the progression of renal impairment in patients with CKD.

Early detection of newborns with congenital immune errors has become possible as yet thanks to the recent nationwide introduction of expanded neonatal screening into routine practice. The stake of false-positive results is higher in premature infants than in other age groups. This therefore requires further and more thorough investigation of both TREC and KREC dynamics in preterm infants. The purpose of this research was to identify significant factors affecting the levels of TREC and KREC in infants born with extremely low birth weight and to evaluate the dynamics of these parameters depending on the gestational age. Materials and methods used: the study that involved 43 (51,2% (22) girls/48,8% (21) boys) extremely low birth weight newborns with gestational age of 26 [25; 27] weeks who were born at the Perinatal Center with the Voronezh Oblast Regional Clinical Hospital No. 1 (Voronezh, Russia) in 2022-2024 had been carried out. The dynamics of TREC and KREC indicators from the gestational age was evaluated. The influence of significant prenatal and postnatal factors on TREC and KREC indicators was considered. The material for the study was dried blood spots drawn on Guthrie cards and taken as part of neonatal screening. Results: it was revealed that TREC levels increased, KREC values remained relatively stable with increasing gestation period. A decrease in TREC levels is observed in newborns who were born to mothers whose pregnancy was complicated by fetoplacental insufficiency (p=0,012) as well as in those who had required the extended cardiotonic support aiming to stabilize the main hemodynamic parameters (p=0.042). A decrease in KREC levels was observed in newborns from mothers with a history of two and more frozen pregnancies (p&lt;0,001). Conclusion: statistically significant prenatal and postnatal factors affecting TREC and KREC levels in children born with extremely low birth weight have been revealed. The dynamics of TREC/KREC indices depending on the gestational age was noted.

Клинико-эпидемиологические особенности системной красной волчанки у детей: данные наблюдений ГБУЗ “Морозовская ДГКБ ДЗМ”

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of unknown etiology characterized by hyperproduction of autoantibodies. The problems of timely diagnosis and identification of predictors of an unfavorable outcome of SLE are relevant due to the variable clinical picture and a high risk of 5-year mortality in the absence of treatment. The purposes of this research were to assess the frequency of various variants of SLE onset, to identify trigger factors contributing to the development of the disease and to analyze the degree of disease activity in children. Materials and methods used: a single-center cohort retrospective study was conducted involving patients aged 9 to 17 y/o who had undergone inpatient treatment at the rheumatological department of the Morozov Children’s City Clinical Hospital (Moscow, Russia) in 2020-2023, specifying age, gender, assessing the frequency of observed symptoms of SLE onset, disease activity according to the SLEDAI scale, laboratory parameters and drug treatment. Results: total of 45 records were analyzed: 75.5% (34) girls/24.5% (11) boys; median age 15 [13; 15] y/o; most frequent clinical syndrome was cutaneous (75.5%); kidney damage was noted in 40% of cases. 86.6% had hematological disorders as follows: thrombocytopenia and leukopenia (48.9%), anemia (46.6%): Coombs-positive anemia (71.4%), lymphopenia (37.7%) and increased ESR (66.6%). Antinuclear factor (ANF Hep2) was detected in all cases. According to the SLEDAI-2K scale, the median disease activity was 11 [7; 16] points. Low disease activity (less than 6 points) was observed in 4.4% (2), average (6 to 10 points) in 44.4% (20), high (11 to 19 points) in 37.7% (17), above average (over 20 points) in 13.3% (6). Moreover, disease activity was higher in girls (p=0.940) and a relationship was found between the time required for diagnosis and disease activity according to the SLEDAI-2K scale (p=0.206). Drug therapy: glucocorticoids (GCS) orally in all cases, intravenous pulse GCS therapy in 71.0%. Hydroxychloroquine therapy was prescribed in 100.0%, mycophenolate mofetil in 57.7%, intravenous immunoglobulin in 37.7%, cyclophosphamide in 13.3%, methotrexate in 6.6%, biological therapy in 31.0%, the drug of choice was rituximab. Conclusion: updating the data on the frequency of various variants of SLE debut as well as identifying the new trigger factors contributing to the development of the disease are necessary steps aiming to increasing the awareness of the SLE course with its debut in childhood, optimizing the diagnosis process and reducing the risk for complications.

Clinical and Pathological Characteristics of Bladder Cancer in Patients Aged 18–45 Undergoing Transurethral Resection of Bladder Tumor

Background and Objectives: Bladder cancer in patients under 45 is poorly characterized and rarely described, with variabilities in clinical outcomes and tumor properties. Our study aimed to elucidate the clinical and pathological features and outcomes of bladder cancer in this younger demographic to better inform management strategies. Materials and Methods: We conducted a retrospective analysis at the Urology Department of “Pius Brînzeu” County Emergency Clinical Hospital in Timișoara, Romania, on 60 patients aged 18–45 who underwent transurethral resection of bladder tumor (TURBT) during a 9-year period. Results: The cohort had a mean age of 38.5 ± 5.6 years with a male predominance (70%). Most tumors were non-muscle-invasive (NMIBC; 80%), with 16.7% being papillary urothelial neoplasms of low malignant potential (PUNLMP), 50% stage pTa, and 30% stage pT1. High-grade tumors were present in 43.3% of the patients. Recurrence occurred in 40% of the patients, while progression was observed in 16.7%. The 3-year overall survival rate was 93.3%, and the progression-free survival rate was 83.3%. Patients with high-grade tumors had a significantly higher recurrence rate (61.5% vs. 23.5%, p = 0.003) and lower survival rates compared to those with low-grade tumors. Conclusions: Young patients predominantly present with low-to-intermediate-stage tumors, yet a significant portion exhibit high-grade tumors associated with poorer outcomes. These findings suggest that while bladder cancer in younger patients tends to be less invasive, aggressive follow-up and treatment are crucial in those with high-grade tumors.

Алгоритмы диагностики дилатации проксимальной грудной аорты в педиатрической практике

Aortic dilation may manifest in childhood subsequently resulting in the formation of an intramural hematoma or dissection. The asymptomatic nature of the disease and the absence of unified echocardiographic algorithms for its detection contribute to its underestimation and the inability to implement timely monitoring of patients. The purpose of this research was to develop algorithms for diagnosing dilation of various parts of the thoracic aorta in children using cardiac ultrasound - echocardiography (ECHO). Materials and methods used: a single-center cross-sectional study had been carried out on the basis of the cardiological department of the Z.A. Bashlyaeva Children’s City Clinical Hospital of the Moscow Department of Healthcare (Moscow, Russia): 11,516 primary ECHO protocols in patients aged 7 and up to 18 y/o, 7.5% (869) of which had records regarding aortic dilation, were identified. 572 with hemodynamically significant CHD were excluded from the study therefore the remaining 297 (76.8% (228) boys) with a median age of 14.2 (11.3; 16.4) y/o were studied for the parameters as follows: internal diameters of the aorta at the level of the sinuses of the Valsalva (SV), sinotubular junction (STJ) and ascending aorta (AAo) in systole. Aortic dilation was defined as a size exceeding 2z at any level, and an aneurysm was defined as exceeding 3z. Results: a total of 116 had a bicuspid aortic valve (BAV), 181 demonstrated a tricuspid valve (TAV) without significant concomitant heart pathology (“idiopathic dilation” (IDAo)). Dilation and AAo aneurysm were more prevalent than in the SV region (73.4% v 28%, р&lt;0.001 and 25.2% v 3.7%, р&lt;0.001, respectively). The presence of BAV was identified as a significant risk factor, in which AAo dilation occurred more frequently than in TAV (1.96 times higher, 95% CI 1.12-3.44, p=0.017) and AAo aneurysm occurred with a 3.07 times higher frequency (95% CI 1.79-5.25 р&lt;0.001). Conclusion: the structure of aortic pathology in children is dominated by AAo dilation. ECHO requires visualization of the entire proximal aorta, not merely the aortic valve and SV that are typically assessed in outpatient practice. Authors represent a diagnostic algorithm and methodological guidelines for assessing the condition of the aorta in children.
