Portal Vein Thrombosis in Patients with Liver Cirrhosis: What Went Wrong?

Purpose: This study aimed to explore inflammatory biomarkers, stool's functional bacterial groups and their possible link to portal vein thrombosis (PVT) in patients with liver cirrhosis (LC). Materials and Methods: An observational study of 300 participants: 200 inhospital cirrhotic patients, who met inclusion criteria, equally assigned into two groups, based on the presence or absence of PVT and 100 healthy controls was carried out. Results: The PVT group displayed significant differences related to older age, cigarettes smoking history, emergency admission, higher Child-Pugh score, metabolic related disorders and nonalcoholic fatty liver disease, as well as non-obstructive aspects, with chronic thrombi. The PVT group exhibited significant differences related to biomarkers such as tumor necrosis factor (TNF)-alpha, C-reactive protein (CRP), D-dimers (D-D), as well as gut overall dysbiosis (DB) and alteration of different functional bacterial groups of the gut microbiota. Strong positive correlations were observed between PVT severity, and TNF-alpha, CRP, D-D as well as lipopolysaccharide (LPS) positive bacteria. Esophageal varices, age and abdominal pain were independent predictors for PVT severity as well as CRP, TNF-alpha and D-D. Conclusion: Patients with LC and PVT displayed elevation of TNF-alpha, CRP, D-D alterations of the functional gut microbiota, as well as several morphological and clinical particularities. Although the LPS positive gut microbiota was linked to inflammatory biomarkers and PVT severity, it was not proven to be an independent predictor of the PVT severity like CRP, TNF-alpha and D-D.

Club Cells-A Guardian against Occupational Hazards.

Club cells have a distinct role in the epithelial repair and defense mechanisms of the lung. After exposure to environmental pollutants, during chronic exposure, the secretion of club cells secretory protein (CCSP) decreases. Exposure to occupational hazards certainly has a role in a large number of interstitial lung diseases. According to the American Thoracic Society and the European Respiratory Society, around 40% of the all interstitial lung disease is attributed to occupational hazards. Some of them are very well characterized (pneumoconiosis, hypersensitivity pneumonitis), whereas others are consequences of acute exposure (e.g., paraquat) or persistent exposure (e.g., isocyanate). The category of vapors, gases, dusts, and fumes (VGDF) has been proven to produce subclinical modifications. The inflammation and altered repair process resulting from the exposure to occupational respiratory hazards create vicious loops of cooperation between epithelial cells, mesenchymal cells, innate defense mechanisms, and immune cells. The secretions of club cells modulate the communication between macrophages, epithelial cells, and fibroblasts mitigating the inflammation and/or reducing the fibrotic process. In this review, we describe the mechanisms by which club cells contribute to the development of interstitial lung diseases and the potential role for club cells as biomarkers for occupational-related fibrosis.

Comparison of Composite Lipid Indices in Patients with Obstructive Sleep Apnoea.

Purpose: Obstructive sleep apnoea (OSA) is a recognised risk factor for cardiovascular disease. However, it is difficult to evaluate the risk of cardiovascular disease in patients with OSA due to multiple shared risk factors. Composite lipid indices, such as atherogenic index of plasma (AIP), visceral adiposity index (VAI) and lipid accumulation product (LAP) have been shown to predict cardiovascular disease better than their individual lipid components. This study aimed to evaluate these indices in patients with OSA. Patients and Methods: Six hundred sixty-seven (667) patients with OSA and 139 non-OSA control volunteers participated in the study. Fasting serum triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C) levels were measured, and AIP, LAP and VAI were calculated following cardiorespiratory polygraphy. The relationship between lipid parameters, OSA and its comorbidities was evaluated using receiver operating curve (ROC) analysis. Results: We found a significant difference in all lipid parameters between OSA patients and controls. Comparing ROCs, LAP was significantly more strongly associated with OSA compared to all the other parameters. The optimal cut-off value for LAP to detect OSA was 76.4, with a sensitivity of 63% and a specificity of 76%. In addition, LAP was the best parameter to predict hypertension and diabetes in patients with OSA, and it was predictive for ischaemic heart disease together with HDL-C. Conclusion: Our results support the use of LAP in clinical practice when evaluating cardiovascular risk in patients with OSA. However, the optimal cut-off value should be determined in large-scale follow-up studies.

Perspectives on Mass Media and Governmental Measures during the 2020 COVID-19 Pandemic in a Romanian Sample of Healthcare Practitioners.

OBJECTIVE: Along with the rapid spread of the COVID-19 pandemic around the globe, a proliferation of mass media information exposed the population to an infodemic with various implications documented worldwide. The present study analyzed Romanian healthcare practitioners' (HCPs) appraisal of COVID-19 mass media information and governmental measures throughout 2020, ranking vaccination priorities and moral values. METHODS: 97 HCP completed a cross-sectional survey with items referring to the COVID-19 pandemic in 2020. RESULTS: Findings were consistent with other studies, indicating an overall negative appraisal of mass media information, which predicted anxiety and relaxation difficulties. Unlike other studies, our sample reported a moderate level of satisfaction with official measures in 2020, which was not related to their view on mass media information. The ranking of population categories in the vaccination order showed similarities with the governmental vaccination program in 2021. Despite placing freedom third after health and love in the hierarchy of values, HCPs showed a high tendency of limiting individual liberty for the common good. CONCLUSIONS: Results showed a dissociation between the overall negative appraisal of mass media information and the satisfaction with governmental measures in 2020. Romanian HCPs shared a secular perspective on moral values and assumed an authoritarian position.

NMDA Autoimmune Encephalitis and Severe Persistent Hypokalemia in a Pregnant Woman.

Introduction: For more than a decade, NMDAR autoimmune encephalitis has been studied and treated as a neurological condition, and good results have been achieve through immune therapies. Apart from being well represented in the CNS, NMDA receptors are currently known of and being studied in multiple non-neuronal cells with potential clinical significance. The association of NMDAR autoimmune encephalitis with pregnancy is rare, and hypokalemia is not mentioned. Methods: We present the case of a 30-year-old woman with NMDAR autoimmune encephalitis in her 17th week of pregnancy associated with persistent hypokalemia that had no apparent cause and resisted Kalium chloride supplementation. A diagnostic work-up including clinical, laboratory, and imagistic examinations, was performed. The case was monitored between May and September 2016 at Neurology, SCJUT. Results: Severe hypokalemia with normal serum sodium levels persisted throughout the course of clinical manifestation of anti-NMDAR autoimmune encephalitis. Conclusions: NMDAR autoimmune encephalitis is under-diagnosed in its atypical clinical variants, and this disease's association with hypokalemia is not mentioned in the literature. Still, it is of clinical importance because it attests to the implications of other organs/systems in the general autoimmune process of NMDAR encephalitis, and it might change the way we address certain psychiatric disorders by searching underlying organic conditions.

Stress and Bio-Ethical Issues Perceived by Romanian Healthcare Practitioners in the COVID-19 Era.

OBJECTIVE: The COVID-19 pandemic had a major impact on different areas of life, especially in the medical system. Because of the pandemic outbreak, the medical system was remodeled to treat COVID-19 patients in secure conditions. Those changes and restrictive measures have put pressure on individual adaptability. The present study investigated the stress of Romanian healthcare practitioners (HCP) and the capacity to deal with new bio-ethical issues that emerged during the COVID-19 pandemic in 2020. METHODS: We analyzed results from a survey on 97 Romanian HCP in several areas: personal experience with COVID-19, perceived emotional distress, and appraisal of bio-ethical principles respected or infringed during the pandemic in 2020. RESULTS: Unlike previous studies, our respondents reported low to moderate stress levels. In addition, few bio-ethical principles were infringed on a personal level. Tendencies to sacrifice individual autonomy and make decisions affecting patients and co-workers were more prevalent among HCP with over 30 years of experience. CONCLUSIONS: Retrospectively, Romanian HCP in our sample appeared to share an embellished view of the COVID-19 pandemic in 2020. Potentially related factors and coping mechanisms with stress are discussed.

Additional factors to corelate with a more than 30% NIHSS score improvement in patients 7 days after fibrinolytic and/or endovascular treatment for ischemic stroke.

BACKGROUND: Our objective was to find which additional factors can influence the favorable result in stroke patients after receiving fibrinolytic and/or endovascular treatment, quantified as a more than 30% improvement of the NIHSS score at 7 days. METHODS: This is a retrospective study to find factors that could influence a favorable evolution of patients with stroke that underwent fibrinolytic and or thrombectomy using the NIHSS score changes. At the admission in the hospital, blood glucose, blood count, coagulation time, INR, aPTT, PT, platelet count, NIHSS questionnaire and ASPECTS score were collected. NIHSS was assessed at the admission, after 1 h, after 2 h, after 24 h and after 7 days. RESULTS: As compared to the initial evaluation, at 7 days after admission 59% (72) of patients have improved with more than 30% the NIHSS. Higher levels of systolic blood pressure, glycemia and lower ASPECTS score at admission were observed in non-achievers. The value of INR contributed to model: for every unit increase of INR, the chance of better outcome decreases by 90,1%. High glycemia has also a negative impact: for every unit increase, the chance of better outcome decreases by 24%. Higher initial ASPECTS score is associated with better outcomes: each point increase of ASPECTS score at initial evaluation, increases the chance of better outcome by 154.2%. CONCLUSION: Males, older age, diabetes, and hyperglycemia correlate with a worse outcome after cerebral stroke regardless of the benefit yielded fibrinolytic and/or thrombectomy therapy. In this study, patients with the above-mentioned factors did not improve more than 30% of baseline NIHSS score from admission to the 7th day.

Migraine without Aura and Subclinical Atherosclerosis in Young Females: Is Gut Microbiota to Blame?

Background and Objectives: Migraine with aura (MA) could be considered a risk factor for developing atherosclerosis and cardio-vascular events. However, less is known about the relation between migraine without aura (MWA) and atherosclerosis. Our study aimed to assess whether young female migraineurs, with alterations of gut microbiota could associate early atherosclerosis. Materials and Methods: We conducted an exploratory cross-sectional, pilot study concerning 105 consecutive young females having MWA, with recent normal brain scans, that were free of cardio-vascular risk factors, non-smokers, not on oral contraception, not pregnant, and without thyroid or parathyroid diseases, chronic organ failure, cancer, or on probiotic or antibiotic treatment. Consecutive to assessment of gut microbiota, patients were assigned to two groups: dysbiosis positive (n = 45) and dysbiosis negative (n = 60). All study participants underwent clinical examinations with an assessment of migraine severity, body mass index and carotid intima-media thickness (CIMT), as well as laboratory workups. Statistical analysis was performed using a chi-squared test (χ2), a two-tailed t-test and a nonparametric Spearman's correlation test. Results: The dysbiosis positive migraineurs showed a significant increase in CIMT along with several anthropometrical, biological and clinical particularities. Significant positive correlations between dysbiosis and CIMT, glycosylated hemoglobin, migraine severity and duration, tumor necrosis factor-alpha, and body mass index were found. Conclusions: Young female migraineurs with significant alterations of gut microbiota experienced early signs of atherosclerosis and displayed severe migraine disability, as well as multiple biological and clinical particularities.

SAS score: Targeting high-specificity for efficient population-wide monitoring of obstructive sleep apnea.

PROPOSAL: This paper investigates a novel screening tool for Obstructive Sleep Apnea Syndrome (OSAS), which aims at efficient population-wide monitoring. To this end, we introduce SASscore which provides better OSAS prediction specificity while maintaining a high sensitivity. METHODS: We process a cohort of 2595 patients from 4 sleep laboratories in Western Romania, by recording over 100 sleep, breathing, and anthropometric measurements per patient; using this data, we compare our SASscore with state of the art scores STOP-Bang and NoSAS through area under curve (AUC), sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV). We also evaluate the performance of SASscore by considering different Apnea-Hypopnea Index (AHI) diagnosis cut-off points and show that custom refinements are possible by changing the score's threshold. RESULTS: SASscore takes decimal values within the interval (2, 7) and varies linearly with AHI; it is based on standardized measures for BMI, neck circumference, systolic blood pressure and Epworth score. By applying the STOP-Bang and NoSAS questionnaires, as well as the SASscore on the patient cohort, we respectively obtain the AUC values of 0.69 (95% CI 0.66-0.73, p < 0.001), 0.66 (95% CI 0.63-0.68, p < 0.001), and 0.73 (95% CI 0.71-0.75, p < 0.001), with sensitivities values of 0.968, 0.901, 0.829, and specificity values of 0.149, 0.294, 0.359, respectively. Additionally, we cross-validate our score with a second independent cohort of 231 patients confirming the high specificity and good sensitivity of our score. When raising SASscore's diagnosis cut-off point from 3 to 3.7, both sensitivity and specificity become roughly 0.6. CONCLUSIONS: In comparison with the existing scores, SASscore is a more appropriate screening tool for monitoring large populations, due to its improved specificity. Our score can be tailored to increase either sensitivity or specificity, while balancing the AUC value.

Migraine in young females with irritable bowel syndrome: still a challenge.

Migraine without aura is frequently reported in female patients with irritable bowel syndrome (IBS), but knowledge about the relationship between these two conditions is still lacking. This study was aimed to explore the particularities of migraine without aura in young female patients with IBS in order to establish a possible link between them. From a cohort of young female patients hospitalized with IBS in the Internal Medicine Department, 30 joined this pilot study, and they were assigned into two groups on the basis of presence or absence of migraine. In this sample, 15 patients have mild to moderate migraine without aura, with a recently taken normal brain scan, and 15 were without migraine. Diseases and conditions not related to migraine and other possible specific female comorbidities were ruled out. Patients undertook a thorough clinical examination in order to assess fibromyalgia (FM) and chronic pelvic pain (CPP), Questionnaires for migraine disability assessment (MIDAS) and generalized anxiety disorder (GAD) were performed. Laboratory testing of blood, urine, and stool were also performed. Optimized lymphocyte proliferation test for food allergy (FA) and a fecal microbiota (microbiological semiquantitative method) for dysbiosis (DB) assessment were performed. Based on the results, migraine-positive group displayed more severe comorbidities: FM (p=0.0002), FA (p=0.0006), CPP (p=0.026), higher scores of anxiety (GAD, p=0.0008), and more severe DB (p=0.0009). We noticed a strong positive correlation between MIDAS and GAD (r=0.83), a good positive correlation between MIDAS and DB (r=0.56), and a moderate positive correlation between MIDAS, FM, and FA (r=0.46 and 0.41). In conclusion, young female patients with IBS and migraine without aura displayed more severe associated issues - anxiety, intestinal DB, FM, FA, and CPP. The severity of migraine correlated well with anxiety range and DB magnitude and moderately with FM and FA.

Nonmotor gastrointestinal disorders in older patients with Parkinson's disease: is there hope?

Despite the fact that nonmotor symptoms (NMS) like gastrointestinal (GI) complaints are frequently reported in Parkinson's disease (PD), no therapeutic guidelines are available. This study aimed to manage some lower GI-NMS in a group of patients with PD. A total of 40 patients (17 males, 23 females; mean age 76.05±2.09 years) were randomly selected for this study. Patients were confirmed to have PD (modified Hoehn-Yars scale: 2.075±0.4) who had undergone levodopa or dopamine agonist treatment. In the non-motor symptoms questionnaire (NMS-Quest), regarding GI complaints, the following were recorded: abdominal pain, bloating, and constipation of mild-to-moderate severity. Laboratory studies, abdominal ultrasound, and upper and lower digestive endoscopies were performed to rule out organic issues. All patients increased their water intake to 2 L/d and alimentary fiber to 20-25 g/d. Twenty patients received trimebutine 200 mg three times daily half an hour before meals. The other 20 patients received probiotics (60 mg per-tablet of two lactic bacteria: Lactobacillus acidophilus and Bifidobacterium infantis), 2×/d, 1 hour after meals for 3 months along with the reassessment of GI complaints. Our results demonstrated that there were significant statistical differences in all assessed symptoms in the first group: 1.55±0.51 vs 0.6±0.5 (P<0.0001) for abdominal pain; 1.6±0.5 vs 0.45±0.51 (P<0.0001) for bloating; and 1.5±0.51 vs 0.85±0.67 (P=0.0014) for constipation with incomplete defecation. The second group displayed statistical differences only for abdominal pain 1.45±0.51 vs 1.05±0.69 (P=0.00432) and bloating 1.4±0.5 vs 0.3±0.47 (P<0.0001). For constipation with incomplete defecation, there was a slight improvement. Thus, there was no significant statistical difference: 1.35±0.49 vs 1.15±0.49 (P=0.2040). In conclusion, lower GI-NMS are frequently present, isolated or associated with other autonomic issues, even before the diagnosis of PD. Treatment with probiotics could improve abdominal pain and bloating as much as with trimebutine, but less for constipation with incomplete evacuation, where trimebutine showed better results.

Obesity in association with Sleep Apnea Syndrome as predictor for coronary-vascular comorbidities.

BACKGROUND AND AIMS: Sleep apnea syndrome (SAS) is a common disorder with growing awareness. We sought to evaluate if the presence of obesity in patients with SAS is associated with a high risk for development of coronary-vascular comorbidities. METHODS: We performed a retrospective study that included 1370 patients (30.3% female and 69.7% male) diagnosed with SAS from May 2005 to May 2012. The collected data included body mass index (BMI), waist/ hip ratio, abdominal, neck, hip circumference and Epworth Sleepiness Scale. The positive diagnostic of SAS was based on apnea-hypopnea index (AHI) provided by polysomnography, and patient comorbidities were obtained from the sleep laboratory records. RESULTS: From the total of 1370 patients, 989 (72%) had grade I to III obesity, 305 (22%) were overweight and only 76 (6%) had a normal weight. Cardiovascular comorbidities were presented in 60.6% of patients, with coronary disease ranking first (34.2%) followed by heart failure (22.6%) and stroke (3.8%). The predictors for cardiovascular comorbidities were coronary disease (OR 2.1, 95% Cl 1.20-3.39, p = 0.0063), heart failure (OR 3.44, 95% Cl 1.60-7.74, p < 0.001) but not stroke (OR 2.3 95% Cl 0.57-13.84, p = 0.357). Analyzing the polysomnography parameters we found a strong correlation for AHI (p < 0.0001), oxygen desaturation index (p < 0.0001) and mean average oxyhaemoglobin saturation (p < 0.0001). CONCLUSIONS: Overweight and obese patients with SAS have a poor outcome, being at high risk of developing other comorbidities like coronary disease and heart failure.

[What is new in the interpretation of polysomnography according to the revised manual for sleep staging in adults? A comparative analysis]. / Ce aduce nou interpretarea polisomnografiei dupa manualul revizuit de stadializare a somnului la adult? Analiza comparativa.

Aim of this paper is to compare the new polysomnography staging manual according to American Academy of Sleep Medicine with Rechtschaffen & Kales rules, underlying the newly introduced aspects and illustrated with polysomnographic images. The new rules simplify the staging but increase the time of electrodes application. They were established on the base of low levels of evidence, without being included in the multicenter statistical validation. For the first time in literature are given details about the criteria for the interpretation of sleep in children, but there are problems still remain unanswered, such as those regarding the scoring of hypopnea. In Romania, the main problem is primarily limited access to investigation and the deficit of health professionals.
