Plasma-Rich Fibrin-Regenerative Material in Tympanic Membrane Surgery.

Background and Objectives: Platelet-rich fibrin (PRF) membrane plays an important role in cell proliferation and aids in healing. This study aimed to assess the safety and efficacy of the addition of PRF to the graft in tympanoplasty. Materials and Methods: A retrospective study was conducted involving 47 patients with chronic dry eardrum perforation, who were candidates for different types of tympanoplasty (type I-IV). The study took place in the ENT department, County Emergency Clinical Hospital of Cluj-Napoca. In group 1 (27 patients) tympanoplasty was performed with a cartilage graft, while in group 2 (20 patients) a cartilage graft was used with the addition of a PRF membrane. The PRF clot was extracted and transformed into a thin membrane. Postoperative evaluation included otoendoscopy and otomicroscopy at 1, 3, 6, and 12 months after surgery, as well as pure-tone audiometry at 12 months. Results: Postoperative follow-up at 1, 3, 6, and 12 months showed a higher rate of graft survival in the PRF group than in the non-PRF group. At the 12-month mark, a successful outcome was observed in 95.0% of patients in the PRF group, while the success rate in group 1 was 70.4% (p < 0.05). The postoperative hearing threshold value was statistically significantly lower in the group with PRF, compared to the non-PRF group, being 18.4 ± 10.4 dB and 27.6 ± 16.2 dB (p < 0.001), respectively. Although the postoperative air-bone gap value did not differ significantly between groups, there was a greater improvement in the PRF group (p < 0.7). The PRF was well tolerated, and the incisions healed perfectly. Conclusions: The PRF membrane increases the rate of autograft survival and is therefore an effective material for patients with chronic perforations of the tympanic membrane.

Predictors of Short-Term Mortality in Patients with Ischemic Stroke.

Background and Objectives: The purpose of this study is to investigate the predictive factors for intrahospital mortality in ischemic stroke patients. We will examine the association between a range of clinical and demographic factors and intrahospital mortality, including age, sex, comorbidities, laboratory values, and medication use. Materials and Methods: This retrospective, longitudinal, analytic, observational cohort study included 243 patients over 18 years old with a new ischemic stroke diagnosis who were hospitalized in Cluj-Napoca Emergency County Hospital. Data collected included the patient demographics, baseline characteristics at hospital admission, medication use, carotid artery Doppler ultrasound, as well as cardiology exam, and intrahospital death. Results: Multivariate logistic regression was used to determine which variables were independently associated with intrahospital death. An NIHSS score > 9 (OR-17.4; p < 0.001) and a lesion volume > 22.3 mL (OR-5.8; p = 0.003) were found to be associated with the highest risk of death. In contrast antiplatelet treatment (OR-0.349; p = 0.04) was associated with lower mortality rates. Conclusions: Our study identified a high NIHSS score and large lesion volume as independent risk factors for intrahospital mortality in ischemic stroke patients. Antiplatelet therapy was associated with lower mortality rates. Further studies are needed to explore the potential mechanisms underlying these associations and to develop targeted interventions to improve patient outcomes.

An updated guide in the management of psoriasis for every practitioner.

BACKGROUND: Psoriasis is one of the most common chronic cutaneous skin disorders, having genetic and immunological components. It is currently unknown what exactly triggers it, or how far reaching are the etiological factors, although great strides have been made in uncovering the pathophysiological cascade. Presently, there is a wide diversity of treatment methods for psoriasis, yet not all are applicable for each patient. Selection of both drug and dosage depends on both the knowledge and experience of the treating dermatologist and also on the specific characteristics of each patient. Therefore, the treating physicians should be made aware of the management possibilities, their advantages and their side effects. METHODS: We have performed a non-systematic literature review on the current treatment methods for psoriasis. We have included the studies, articles, and prescription information that provided the most relevant information regarding each therapeutic agent. Afterward, we divided the treatment methods according to delivery and illustrated the management protocols for adult, paediatric, and pregnant patients. DISCUSSION AND CONCLUSIONS: Current therapies are divided into topical drugs, phototherapy, systemic and biological agents. Topical therapies and phototherapy are generally the first and second line of management respectively, being typically effective in treating mild to moderate forms of psoriasis. On the other hand, the chronic moderate to severe forms usually benefit from systemic drugs, whereas biologic agents are reserved for severe or unremitting cases, especially those suffering from psoriatic arthritis. Also of importance is the understanding of the pathophysiological mechanisms in psoriasis and how the selected drugs interfere in the pathological cascade. Furthermore, physicians should be able to recommend the appropriate therapy not only for adults but also for paediatric and pregnant patients as well. In the following manuscript, we present an updated version of these management options, alongside their indications, posology and most common side effects, a guide that may be useful for every practitioner in this field.

The impact of continuous positive airway pressure on cardiac arrhythmias in patients with sleep apnea.

BACKGROUND: Obstructive sleep apnea (OSA) can lead to cardiac complications: brady and tachyarrhythmias and sudden cardiac death. Continuous positive airway pressure (CPAP) is the gold standard for the treatment of OSA. The present study aims to demonstrate the efficiency of CPAP in the treatment of cardiac arrhythmias in patients with OSA. The study also recorded the frequency of arrhythmias in patients with untreated OSA and assessed the association between the severity of OSA and the occurrence of arrhythmias. MATERIALS AND METHODS: This is a prospective cohort study. Ninety-three patients with OSA were included, aged 60 (58-64) years, with female/male sex ratio of 1:4. They were subjected simultaneously to home respiratory polygraphy examination and Holter electrocardiogram monitoring, in two different stages: at diagnosis and at the 3-month checkup after CPAP treatment. The presence of supraventricular and ventricular arrythmias was noted. Respiratory parameter values were also recorded. RESULTS: Statistically significant decrease in the occurrence of supraventricular (P < 0.001) and ventricular extrasystoles (P < 0.001), atrial fibrillation (AF) (P = 0.03), nonsustained ventricular tachycardia (NSVT) (P = 0.03), and sinus pauses (P < 0.001) was observed 3 months after treatment with CPAP, compared with baseline. The apnea-hypopnea index (AHI) was correlated with the ventricular extrasystoles (r = 0.273; P = 0.008). The ejection fraction of the left ventricle was inversely correlated with the episodes of NSVT (r = -0.425; P < 0.001). AF was associated with the longest apnea (r = 0.215; P = 0.04). Cardiac activity pauses were correlated with AHI (r = 0.320; P = 0.002), longest apnea (r = 0.345; P = 0.01), and oxygen desaturation index (r = 0.325; P = 0.04). CONCLUSION: The prevalence of cardiac arrhythmias in patients with OSA was reduced after 3 months of CPAP therapy. Cardiac arrhythmias were correlated with the severity of OSA.

Systemic and Local Factors' Influence on the Topological Differences in Deep Vein Thrombosis.

Background and Objectives: Deep vein thrombosis (DVT) is a common cause of intra-hospital morbidity and mortality, and its most severe complication is pulmonary thromboembolism. The risk factors that influence the apparition of DVT are generally derived from Virchow's triad. Since the most severe complications of DVT occur in proximal rather than distal deep vein thrombosis, the aim of this study was to identify the factors influencing the apparition of proximal DVT. Materials and Methods: This was a transversal, cohort study. The study included 167 consecutive patients with lower limb DVT over a two-year period. The following data were recorded or determined: general data, conditions that are known to influence DVT, medical history and coagulation or thrombophilia-related genetic variations. Results: In the univariate analysis, male gender, neoplasia, previous DVT and mutated factor V Leiden were all associated with proximal DVT, while bed rest was associated with distal DVT. In the multivariate analysis, male gender, previous DVT and factor V Leiden mutation were independently correlated with proximal DVT, while bed rest was independently associated with distal deep vein thrombosis. Conclusion: Our observations point out that the factors indicating a systemic involvement of coagulation were correlated with proximal DVT, while local factors were associated with distal DVT.

Regression and Sentinel Lymph Node Status in Melanoma Progression.

BACKGROUND The purpose of this study was to assess the role of regression and other clinical and histological features for the prognosis and the progression of cutaneous melanoma. MATERIAL AND METHODS Between 2005 and 2016, 403 patients with melanoma were treated and followed at our Department of Dermatology. Of the 403 patients, 173 patients had cutaneous melanoma and underwent sentinel lymph node (SLN) biopsy and thus were included in this study. RESULTS Histological regression was found in 37 cases of melanoma (21.3%). It was significantly associated with marked and moderate tumor-infiltrating lymphocyte (TIL) and with negative SLN. Progression of the disease occurred in 42 patients (24.2%). On multivariate analysis, we found that a positive lymph node and a Breslow index higher than 2 mm were independent variables associated with disease free survival (DFS). These variables together with a mild TIL were significantly correlated with overall survival (OS). The presence of regression was not associated with DFS or OS. CONCLUSIONS We could not demonstrate an association between regression and the outcome of patients with cutaneous melanoma. Tumor thickness greater than 2 mm and a positive SLN were associated with recurrence. Survival was influenced by a Breslow thickness >2 mm, the presence of a mild TIL and a positive SLN status.

The impact of minimal invasive surgery on early complications and mortality after radical cystectomy for muscle-invasive urothelial bladder cancer.

PURPOSE: to evaluate the 30-day death rate and the factors associated with short-term complications after radical cystectomy for muscle-invasive urothelial bladder cancer. METHODS: The study included 123 patients (age 64.1±7.9 years; 111 (90.2%) males and 12 (9.8%) females) previously diagnosed with urothelial bladder cancer, admitted for radical cystectomy in a tertiary center. The following data were noted: age, gender, perioperative chemotherapy and radiotherapy, pre- and postoperative hemoglobin and creatinine levels, tumor stage, type of surgery, type of diversion and Clavien classification. Patients were followed for 30 days and several complications were noted: cardiovascular, gastrointestinal, local, or infectious complications, anemia. Death rate was also recorded. RESULTS: Open cystectomy was performed in 81 (65.9%) patients, and laparoscopic approach was used in 43 (34.1%) patients. An ileal neobladder was created for 11 (8.9%) patients and noncontinent diversion for 112 (91.1%). There were 2 (1.6%) deaths following surgery. The following complication rates were noted: 27 local (22%), 16 infectious (13%), 54 cases of postoperative anemia (43.9%). Postoperative anemia was independently associated with open cystectomy (OR, 5.7; p=0.001), ileal neobladder (Odds ratio/OR, 14.6, p=0.002) and male gender (OR, 0.15, p=0.01). The Clavien classification did not differ between open and laparoscopic cystectomy (p=0.3), even though the complication grade was higher in the former. CONCLUSIONS: The 30-day death rate after radical cystectomy for muscle-invasive urothelial bladder cancer was low. Open cystectomy was associated with more severe short-term complications as compared with the laparoscopic approach. Postoperative anemia was associated with the type of surgery, diversion type and male gender.

Chemotherapy-related infectious complications in patients with Hematologic malignancies.

BACKGROUND: The objective of the present study was to determine the association between chemotherapy and infectious complications in patients diagnosed with Hematologic malignancies (HMs). MATERIALS AND METHODS: The study included 463 patients diagnosed with HMs multiple myeloma (MM), Hodgkin's lymphoma (HL), non-HL (NHL), acute myeloid leukemia (AML), acute lymphocytic leukemia, chronic lymphocytic leukemia, and chronic myeloid leukemia, between January 2014 and June 2015. The patients were followed for 1 year after inclusion, to record the infectious complications. The collected data included age, sex, type of chemotherapy regimen, and several blood tests at admission. All patients received prophylactic treatment with antibiotics and antifungal agents. For each infection, we recorded the microbiological diagnosis and the day of occurrence since HMs diagnosis. RESULTS: In patients with MM, we found that the treatment with growth factors (hazard ratio [HR] 2.2; confidence interval [CI] 95%: 1-4.6; P = 0.03) was associated with a higher chance of infectious complications. In patients with non-Hodgkin lymhoma (LNH), the following drugs were associated with a higher infectious incidence: cytarabine (HR: 2.3; CI 95%: 1-5; P = 0.03), methotrexate (HR: 2.1; CI 95%: 1.8-4; P = 0.01), dexamethasone (HR: 1.7; CI 95%: 0.9-3; P = 0.06), growth factors (HR: 1.7; CI 95%: 0.9-3.2; P = 0.001), and etoposide (HR: 2.5; CI 95%: 1.5-4.2; P = 0.002). Cytarabine (induction) (HR: 2; CI 95%: 1.1-3.7; P = 0.01), cytarabine (consolidation) (HR: 2.1; CI 95%: 1.3-3.5; P = 0.01), and growth factors (HR: 2.1; CI 95%: 1.3-3.5; P = 0.002) were often on the therapeutic plan of patients with AML, which developed infections. CONCLUSION: Regarding the chemotherapy regimen, the highest incidences of infectious complications were observed for growth factors and cytarabine.

Imaging Approach in the Diagnostics and Evaluation of the Psoriasis Plaque: A Preliminary Study and Literature Review.

(1) Background: the aim of the study was to demonstrate its usefulness in the field of imaging evaluation of plaque morphology in psoriasis vulgaris, with an emphasis on the use of confocal microscopy and other advanced skin-imaging techniques. (2) Methods: we conducted a prospective study over two years (July 2022-April 2024), on patients diagnosed with moderate or severe psoriasis vulgaris, treated in the dermatology department of our institution. We selected 30 patients, of whom 15 became eligible according to the inclusion and the exclusion criteria. A total of 60 psoriasis plaques were analyzed by dermatoscopy using a Delta 30 dermatoscope and Vidix 4.0 videodermoscope (VD), by cutaneous ultrasound (US) using a high-resolution 20 MHz linear probe, and by confocal microscopy, along with histopathological analysis. (3) Results: the study included fifteen patients with vulgar psoriasis, diagnosed histopathologically, of whom six were women and nine were men, with an average age of 55. Between two and six plaques per patient were selected and a total of sixty psoriasis plaques were analyzed by non-invasive imaging techniques. Twelve lesions were analyzed with ex vivo fluorescence confocal microscopy (FCM), compared to histology. US showed that the hyperechoic band and the lack of damage to the subcutaneous tissue were the most common criteria. The epidermis and dermis were found to be thicker in the area of psoriasis plaques compared to healthy skin. Dermatoscopy showed that the specific aspect of psoriasis plaques localized on the limbs and trunk was a lesion with an erythematous background, with dotted vessels with regular distribution on the surface and covered by white scales with diffuse distribution. The presence of bushy vessels with medium condensation was the most frequently identified pattern on VD. Good correlations were identified between the histological criteria and those obtained through confocal microscopy. (4) Conclusions: the assessment and monitoring of patients with psoriasis vulgaris can be conducted in a more complete and all-encompassing manner by incorporating dermatoscopy, ultrasonography, and confocal microscopy in clinical practice.

Dysbiosis in Multiple Sclerosis: Can Immunoglobulin Y Supplements Help?

The role of gut microbiota in autoimmune disorders like multiple sclerosis is gaining attention. Multiple sclerosis is characterized by inflammation, demyelination, and neurodegeneration in the central nervous system. Alterations in gut microbiota have been linked to multiple sclerosis development, with decreased beneficial bacteria and increased harmful species. The gut-brain axis is a complex interface influencing bidirectional interactions between the gut and the brain. Dysbiosis, an imbalance in gut microbiota, has been associated with autoimmune diseases. The influence of gut microbiota in multiple sclerosis is reversible, making it a potential therapeutic target. Probiotics, prebiotics, and fecal microbiota transplantation have shown promise in multiple sclerosis treatment, with positive effects on inflammation and immune regulation. Immunoglobulin Y (IgY) supplements derived from chicken egg yolk have potential as nutraceuticals or dietary supplements. IgY technology has been effective against various infections, and studies have highlighted its role in modulating gut microbiota and immune responses. Clinical trials using IgY supplements in multiple sclerosis are limited but have shown positive outcomes, including reduced symptoms, and altered immune responses. Future research directions involve understanding the mechanisms of IgY's interaction with gut microbiota, optimal dosage determination, and long-term safety assessments. Combining IgY therapy with other interventions and investigating correlations between microbiota changes and clinical outcomes are potential avenues for advancing multiple sclerosis treatment with IgY supplements.

The impact of the CYP2C9 and VKORC1 polymorphisms on acenocoumarol dose requirements in a Romanian population.

AIM: To investigate the genotype-phenotype correlation in Romanian patients treated with acenocoumarol. MATERIAL AND METHODS: We studied 301 consecutive patients who required treatment with acenocoumarol, admitted within the Municipal Hospital of Cluj-Napoca and the Heart Institute "Niculae Stanciou" in Cluj-Napoca over a 3-year period. For each patient we recorded clinical parameters which could interfere with the achievement of stable therapeutic international normalized ratio (INR). We performed genetic analysis which consisted of genotyping the CYP2C9 gene and the VKORC1 gene. Patients were divided in three groups according to the acenocoumarol dose needed to reach a stable INR: the low dose group (≤7mg/week), the medium dose group (>7mg and <28mg/week) and the high acenocoumarol dose group (>28mg/week). RESULTS: We found that patients' age was significantly different between groups (p<0.001). No differences existed between groups regarding the pathologies which required anticoagulation therapy or the concomitant treatment. The following parameters increased the odds of receiving a low dose of acenocoumarol: patient's age over 65years (OR, 3.2; p=0.01; 95%CI: 1.24-8.25), the presence of the CYP2C9*3 allele (OR, 3.4; p=0.006; 95%CI: 1.41-8.34), and the GA or AA genotype of c.-1639G>A polymorphism of VKORC1 (OR, 6.5; p=0.01; 95%CI: 1.38-30.5; respectively OR, 11.6; p=0.003; 95%CI: 2.26-59.58). A high acenocoumarol dose was less likely to be administered to an elderly patient (OR, 0.24; p=0.001; 95%CI: 0.1-0.56) or to a patient with the GA or AA genotype (OR, 0.2; p<0.001; 95CI%: 0.09-0.45; respectively OR, 0.05; p=0.006; 95%CI: 0.007-0.43). CONCLUSION: The stable therapeutic dose of acenocoumarol is dependent of patient's age, the presence of the CYP2C9*3 allele and the c.-1639G>A polymorphism of VKORC1.

An acenocoumarol dose algorithm based on a South-Eastern European population.

AIM: To develop and validate an algorithm for the prediction of therapeutic dose of acenocoumarol in Romanian patients. METHODS: The inclusion criteria for entry to the study was age ≥ 18 years and starting acenocoumarol treatment for at least one of the following clinical indications: acute deep vein thrombosis of the lower limbs, persistent or permanent atrial fibrillation, and/or the presence of valvular prostheses requiring prolonged oral anticoagulant therapy. The patients were followed up for 3 months. Patients admitted to the internal medicine, cardiology, and geriatrics wards of the Municipal Clinical Hospital, Cluj-Napoca and "Niculae Stancioiu" Heart Institute between October 2009 and June 2011 who fulfilled the inclusion criteria were included in the study. Clinical and demographic data that could influence the acenocoumarol stable dose were recorded for each patient. Genetic analysis included the genotyping the CYP2C9*2 and *3, and the VKORC1 -1693 G > A polymorphisms. The patients were randomly divided into two groups: (1) the main group on which the development of the clinical and genetic algorithms for acenocoumarol dose prediction was based; (2) the validation group. RESULTS: The study included 301 patients, of whom 155 were women (51.5 %) and 146 were men (48.5 %). The median age of the patient cohort was 66 (women, 57; men, 73) years. After randomization the main group comprised 200 patients (66.4 %) and the validation group 101 patients (33.6 %). Age and body mass index explained 18.8 % (R (2)) of the variability in acenocoumarol weekly dose in patients in the main group. When the genetic data were added to the algorithm, the CYP2C9*2 and *3 polymorphisms and the VKORC1 -1693 G > A polymorphism accounted for 4.7 and 19. 6 % of acenocoumarol dose variability, respectively. For the main group, we calculated a mean absolute error of 5 mg/week (0.71 mg/day). In the validation group, clinical parameters explained 22.2 % of the weekly acenocoumarol dose variability. Genetic polymorphisms increased the R(2) coefficient to 32.8 %. CONCLUSION: We have developed and validated an accurate algorithm for prediction of the stable therapeutic dose of acenocoumarol in a Romania population.

The impact of oral anticoagulants on the characteristics of subdural hematomas and other brain lesions in patients with traumatic brain injury.

Background and aim: The aim of the study was to determine the impact of prior anticoagulant treatment on the characteristics of intracranial hematomas. Methods: We included in this retrospective study 135 patients who were diagnosed with subdural hematoma in the context of traumatic brain injury. We recorded the demographic and clinical data, the paraclinical examinations and the characteristics of subdural hematoma evidenced by preoperative computed tomography (CT). We also reported the other brain injuries, entailed by primary and secondary lesions, as described by CT. Results: The anticoagulation therapy was recorded in 35 patients, at the moment of diagnosis. Acute subdural hematoma was recorded in 89 (65.9%) patients, 21 (60%) of these had anticoagulation therapy on admission. There were 46 (34.1%) patients with chronic subdural hematoma, 14 (40%) of these were on anticoagulant therapy. The midline shift was significantly moved in patients with anticoagulation therapy. The thickness of the subdural hematoma was significantly higher in patients with anticoagulation. We did not find any significant association of the other brain lesions (cranial fracture, extradural hematoma, intraparenchymal hematoma, nor intracranial hypertension, brain herniation, brain swelling), and the presence of anticoagulation therapy. Conclusion: The study showed that anticoagulants significantly influence some neuroimaging aspects of the SDH in head trauma.

Biological Risk Factors Influencing Vascular Cognitive Impairments: A Review of the Evidence.

Vascular cognitive impairment encompasses several types of deficits, ranging from mild cognitive impairment to dementia. Cognitive reserve refers to the brain's ability to balance damage and improve performance through certain types of brain networks. The purpose of this review was to assess the relationship between reserve in vascular impairment, specifically looking at whether cognitive impairment is influenced by cognitive reserve, identifying significant vascular risk factors and their pathological pathways. To achieve this purpose, a review covering these issues was conducted within the Embase, Cochrane, and PubMed database. A total of 657 scientific articles were found, and 33 papers were considered for the final analysis. We concluded that there is no consensus on the protective effects of brain reserve on cognitive impairment. Stroke and diabetes can be considered significant risk factors for vascular cognitive impairment, while hypertension is not as damaging as blood pressure variability, which structurally alters the brain through a variety of mechanisms.

The Management of Obstructive Sleep Apnea Patients during the COVID-19 Pandemic as a Public Health Problem-Interactions with Sleep Efficacy and Mental Health.

With the onset of the COVID-19 outbreak, it was stipulated that patients with obstructive sleep apnea (OSA) may have a greater risk of morbidity and mortality and may even experience changes in their mental health. The aim of the current study is to evaluate how patients managed their disease (sleep apnea) during the COVID-19 pandemic, to determine if continuous positive airway pressure (CPAP) usage changed after the beginning of the pandemic, to compare the stress level with the baseline, and to observe if any modifications are related to their individual characteristics. The present studies highlight the level of anxiety, which was high among patients with OSA during the COVID-19 pandemic (p < 0.05), with its influence on weight control (62.5% of patients with high levels of stress gained weight) and sleep schedule (82.6% reported a change in sleep schedule). Patients with severe OSA and high levels of stress increased their CPAP usage (354.5 min/night vs. 399.5 min/night during the pandemic, p < 0.05). To conclude, in OSA patients, the presence of the pandemic led to a greater level of anxiety, changes in sleep schedule and weight gain because of job loss, isolation, and emotional changes, influencing mental health. A possible solution, telemedicine, could become a cornerstone in the management of these patients.

The role of multiple sclerosis therapies on the dynamic of human gut microbiota.

Gut microbiota, the total microorganisms in our gastrointestinal tract, might have an implication in multiple sclerosis (MS), a demyelinating neurological disease. Our study included 50 MS patients and 21 healthy controls (HC). Twenty patients received a disease modifying therapy (DMT), interferon beta1a or teriflunomide, 19 DMT combined with homeopathy and 11 patients accepted only homeopathy. We collected in total 142 gut samples, two for each individual: at the study enrolment and eight weeks after treatment. We compared MS patients' microbiome with HC, we analysed its evolution in time and the effect of interferon beta1a, teriflunomide and homeopathy. There was no difference in alpha diversity, only two beta diversity results related to homeopathy. Compared to HC, untreated MS patients had a decrease of Actinobacteria, Bifidobacterium, Faecalibacterium prauznitzii and increased Prevotella stercorea, while treated patients presented lowered Ruminococcus and Clostridium. Compared to the initial sample, treated MS patients had a decrease of Lachnospiraceae and Ruminococcus and an increased Enterococcus faecalis. Eubacterium oxidoreducens was reduced after homeopathic treatment. The study revealed that MS patients may present dysbiosis. Treatment with interferon beta1a, teriflunomide or homeopathy implied several taxonomic changes. DMTs and homeopathy might influence the gut microbiota.

Association among VKORC1 rs9923231, CYP4F2 rs2108622, GGCX rs11676382 polymorphisms and acute ischemic stroke.

Acute ischemic stroke is a major cause of morbidity and mortality worldwide, and genetic factors play a role in the risk of stroke. Single nucleotide polymorphisms (SNPs) in the VKORC1, CYP4F2, and GGCX genes have been linked to clinical outcomes, such as bleeding and cardiovascular diseases. This study aimed to investigate the association between specific polymorphisms in these genes and the risk of developing the first episode of acute ischemic stroke in patients without a known embolic source. This retrospective, cross-sectional, observational, analytical, case-control study included adult patients diagnosed with acute ischemic stroke. The SNPs in VKORC1 rs9923231, CYP4F2 rs2108622, GGCX rs11676382 genes were genotyped and analyzed together with the demographic and clinical factors of the 2 groups of patients. The presence of SNPs in VKORC1 or CYP4F2 genes significantly increased the risk of ischemic stroke in the context of smoking, arterial hypertension, and carotid plaque burden. The multivariate logistic model revealed that smoking (odds ratio [OR] = 3.920; P < .001), the presence of carotid plaques (OR = 2.661; P < .001) and low-density lipoprotein cholesterol values >77 mg/dL (OR = 2.574; P < .001) were independently associated with stroke. Polymorphisms in the VKORC1 and CYP4F2 genes may increase the risk of ischemic stroke in patients without a determined embolic source. Smoking, the presence of carotid plaques, and high low-density lipoprotein cholesterol levels were reconfirmed as important factors associated with ischemic stroke.

Admission Emergency Department Point-of-care Biomarkers for Prediction of Early Mortality in Spontaneous Intracerebral Hemorrhage.

BACKGROUND/AIM: Spontaneous intracerebral hemorrhage (sICH) has a significant morbidity and mortality, despite representing a non-dominant hemorrhagic stroke. The aim of the study was to assess the impact of the emergency department (ED) point-of-care (POC) biomarkers on early mortality in sICH patients. PATIENTS AND METHODS: Demographic data, medical history and admission clinical parameters from adult patients with imaging-based sICH diagnosis were collected retrospectively, upon their ED presentation over a period of 18 months. ED-based POC analyzers were used for blood biomarkers [complete blood count, C reactive protein (CRP), glycemia, hepatic and renal function, D-dimer and cardiac troponin I]. Derived inflammatory indexes were calculated. Mortality endpoints were collected (on day 7 and at discharge). RESULTS: Of the 219 included patients, mortality rates reached 30.14% on day 7 and 46.12% at discharge. In the univariate analysis, day 7 mortality was significantly associated with history of diabetes, atrial fibrillation, ongoing anticoagulant treatment, the need of endotracheal intubation and ED cardiopulmonary resuscitation, and the presence of intraventricular hemorrhage and mass effect on the initial CT scan. White blood cells and granulocytes (but not the neutrophil-to-lymphocytes ratio, nor the CRP) were significantly higher in the deceased groups, alongside serum glucose. Derived inflammatory indexes were not significantly correlated with mortality endpoints. Cut-off values of 9.6×109/l for granulocytes and 132 mg/dl for glucose were identified as day 7 mortality predictors. CONCLUSION: sICH is a potentially severe condition causing high early mortality. Emergency department point-of-care biomarkers could represent a readily available and simple to use prognostic tool.

Treatment of psoriasis - unburdened by fear during SARS-CoV2 menace.

In a matter of mere months, humanity was unexpectedly struck by the appearance of SARS-CoV-2, shifting our perception as medical practitioners regarding our day-to-day activity. One especially disconcerting change was patient addressability to medical facilities, as well as access to proper healthcare in various fields. As these changes occurred rapidly, dermatologists too had to adapt by means of teledermatology, giving us back the ability to reach, treat, and comfort our patients. Among the individuals requiring special dermatological attention are those suffering from psoriasis, especially considering that the biological therapies employed in treating this debilitating disease become questionable in the circumstance of the current pandemic. As more evidence surfaces concerning the pathophysiology of SARS-CoV-2, we become closer to understanding which therapies may interfere with its clearance, and which are actually safe to use. This review aims to answer the question, are biological therapies warranted in the treatment of psoriasis during the COVID-19 outbreak, or should they be discontinued?

Paraoxonase 1 and atrial fibrillation: Is there a relationship?

Atrial fibrillation (AF) is associated with oxidative stress and inflammation. Paraoxonase-1 (PON1), circulates in blood bound to high-density lipoproteins and reduces systemic oxidative stress. The aim of this study was to evaluate PON1 serum concentration and PON1 arylesterase activity (AREase) in patients with AF. We studied a group of 67 patients with symptomatic paroxysmal or persistent AF admitted for cardioversion and a control group of 59 patients without AF. Clinical parameters, lipid profile, PON1 concentration and AREase were evaluated. A significant difference in serum PON1 concentration and in AREase was found among the two groups. In a multivariate linear regression model, the presence of AF was associated with low PON1 concentration (P = .022). The body mass index was also independently associated with PON1 values (P < .001). Only the high-density lipoproteins-cholesterol level was independently associated with AREase (P = .002). PON1 serum concentrations and AREase were diminished in patients with AF, and the presence of AF was independently associated with low PON1 values.
