The restoration and maintenance of sinus rhythm is a desirable strategy for many patients with atrial fibrillation (AF) since it has been associated with improvement in symptoms and a better quality of life. Sinus rhythm can be achieved by pharmacological or electrical cardioversion or after catheter ablation of AF. Despite high rates of successful cardioversion, AF recurrence remains a major challenge. Anti-arrhythmic drug therapy currently plays a significant role in maintaining sinus rhythm after cardioversion. Amiodarone is the most commonly prescribed anti-arrhythmic drug for patients with AF. This is due to its particular electrophysiological properties and superior anti-arrhythmic effects in comparison with other anti-arrhythmic drugs. Understanding the cardiac electrophysiology and arrhythmogenesis mechanisms may result in identification of new targets for anti-arrhythmic therapy. The aim of this article was to review amiodarone’s clinical pharmacology and evaluate evidence supporting amiodarone for treatment and prevention of AF recurrence after cardioversion.

Facing severe under-funding and significant workforce maldistribution, the health system in Romania is challenged to provide adequate care for the ageing population. The aim of this article is to connect health labour market data of the geriatrics workforce in Romania with individual perceptions of front-line workers in geriatrics in order to better understand the ‘human’ factors of effective health workforce development. Comprehensive health workforce data are not available; we therefore used a rapid scoping review and interviews to combine quantitative and qualitative data sources, such as the ‘Healthcare Facility Activity Report’, policy documents and available reports. They show that despite a consistent increase in the overall number of geriatricians, their majority is based in Bucharest, the capital city. The initial review points to possible geriatrician burnout, caused in part by high workload. The geriatrics workforce in Romania is poorly developed. Significant efforts are still needed to create policies addressing inflows and outflows, training, maldistribution and inefficiencies related to their practice. Addressing burnout by improving teamwork and collaboration is vital for maintaining and improving the workforce morale and motivation. Two major policy recommendations emerged: an urgent need for better health workforce data in Romania and development of more effective workforce management.

Liver involvement in Coronavirus Disease 2019 (COVID-19) has been widely documented. However, data regarding liver-related prognosis are scarce and heterogeneous. The current study aims to evaluate the role of abnormal liver tests and incidental elevations of non-invasive fibrosis estimators on the prognosis of hospitalized COVID-19 patients. We conducted a retrospective cohort study to investigate the impact of elevated liver tests, non-invasive fibrosis estimators (the Fibrosis-4 (FIB-4), Forns, APRI scores, and aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio), and the presence of computed tomography (CT)-documented liver steatosis on mortality in patients with moderate and severe COVID-19, with no prior liver disease history. A total of 370 consecutive patients were included, of which 289 patients (72.9%) had abnormal liver biochemistry on admission. Non-survivors had significantly higher FIB-4, Forns, APRI scores, and a higher AST/ALT ratio. On multivariate analysis, severe FIB-4 (exceeding 3.25) and elevated AST were independently associated with mortality. Severe FIB-4 had an area under the receiver operating characteristic (AUROC) of 0.73 for predicting survival. The presence of steatosis was not associated with a worse outcome. Patients with abnormal liver biochemistry on arrival might be susceptible to a worse disease outcome. An FIB-4 score above the threshold of 3.25, suggestive of the presence of fibrosis, is associated with higher mortality in hospitalized COVID-19 patients.

Cardiovascular assessment of oncological patients suggests that cancer can lead to subclinical damage of the heart. The aim of the present study was to analyze the value of baseline cardiovascular biomarkers in patients with newly diagnosed colon cancer prior to treatment. Additionally, another aim was to establish baseline cut-off alert values for this low-intensity neoplastic damage. A total of 51 patients with newly diagnosed colon cancer, without history of cardiac disease, were enrolled in a prospective, cross-sectional study. All patients underwent clinical, biochemical and basic echocardiographic evaluation before starting treatment. Patients were assessed for myocardial damage using high-sensitivity troponin T (hs-TnT), creatine kinase-MB (CK-MB) and N-terminal-pro B-type natriuretic peptide (NT-proBNP). A group of 28 healthy controls was included for comparison. Cardiac ultrasound revealed similar left ventricular (LV) ejection fraction but enlarged LV chambers compared with the control group (LV at end systole, 29.50 vs. 26.00 mm; LV at end diastole, 44.50 vs. 38.00 mm; P0.001 in both cases). The levels of cardiovascular biomarkers of myocardial damage were higher in the patients than in the control group (CK-MB, 17.00 vs. 11.00 IU/l, P0.001; hs-TnT, 8.20 vs. 3.00 ng/l, P0.001; NT-proBNP, 155.40 vs. 48.50 pg/ml, P=0.001). In multivariate analysis, CK-MB and hs-TnT retained statistical significance (P=0.004 and P=0.045, respectively). Moreover, it was demonstrated that new cut-offs for hs-TnT (8.00 ng/l) and NT-proBNP (220.00 pg/ml) can identify cardiac damage in patients ≥65 years old. Thus, the present study confirmed the hypothesis that a basic cardiovascular assessment of treatment-naïve patients with colon cancer can identify important pre-treatment myocardial impact. Adapted cut-off values should be set for cardiovascular biomarkers in the cancer population, different from those currently accepted for acute coronary syndromes or heart failure.

(1) Aim: The aim of this study was to assess the preferences of oral anticoagulants (OA) in patients diagnosed with deep vein thrombosis (DVT) of lower limbs or non-valvular atrial fibrillation (AF) requiring anticoagulation for medium/long term. (2) Materials and methods: the study included consecutive patients admitted with a diagnosis of either acute DVT of lower limbs (without signs of pulmonary embolism) or non-valvular AF who required oral anticoagulation, in a time frame of 18 months from January 2017 until June 2018. The following data were recorded: demographic variables, comorbidities (ischemic heart disease, arterial hypertension, heart failure, stroke, peripheral artery disease, diabetes mellitus, obesity), type and dose of OA (acenocoumarol, dabigatran, apixaban, rivaroxaban), complications due to the use of OA. (3) Results: AF patients were older and had considerably more cardiovascular comorbidities than DVT patients. Vitamin K antagonists (VKA) were more likely to be administered in patients with AF, as they had indication for indefinite anticoagulation. VKA were more frequently prescribed in patients with ischemic heart disease, heart failure, and diabetes compared with DVT patients. Moreover, complications related to OA use were more frequent in the VKA group. Almost half of patients with acute DVT (48.5%) were treated with direct OA (DOAC) rather than VKA, and only a quarter of AF patients (24.8%) were treated with DOACs.

Background Demographic changes - such as population ageing - pose great challenges to health systems around the world. For the Romanian health system, challenges might be particularly difficult to address. Facing a severe under-funding and significant workforce maldistribution, the health system in Romania is called to care about both the ageing population and the workforce taking care of the elderly. The aim of this paper is to apply the health labour market framework to the geriatric workforce in Romania. Methods The paper describes the composition and distribution of the geriatrics workforce in Romania based on data in the Healthcare Facility Activity report, policy documents and available reports. Results Geriatric care is provided in Romania mainly by geriatricians employed by public hospitals. The team around geriatricians is limited to nurses only, with other professions - such as psychologists, physiotherapists and social workers - almost absent. Even though the number of geriatricians has increased country-wide over recent years (from 149 to 242), there are significant differences in their distribution at a county level. Eleven counties out of the 41 reporting to have only 1 geriatrician for populations of hundreds of thousands. Training curricula for geriatrics residents fall short of addressing team work and inter-professional collaboration. Reports show growing concern over geriatrician burnout, caused in part by inadequate team work. Faced with burnout risk, many of them report considering changing specialties, which would further aggravate the lack of comprehensive elderly care. Conclusions The geriatrics workforce in Romania is poorly developed, and significant efforts are still needed to develop policies addressing geriatrics production, inflows and outflows, and maldistribution and inefficiencies. Moreover, addressing burnout by improving teamwork and collaboration is vital for maintaining and improving the workforce morale and motivation.

As colorectal cancer (CRC) is one of the forms of cancer with the highest prevalence globally and with a high mortality, screening and early detection remains a major issue. Colonoscopy is still the gold standard for detecting premalignant lesions, but it is burdened by some complications. For instance, it is laborious, with some difficulties of acceptance for some patients, and is ultimately an imperfect standard, given that some premalignant lesions or incipient malignancies can be missed by colonoscopic evaluation. In this context, new non-invasive approaches such as surface-enhanced Raman spectroscopy (SERS) based liquid biopsy have gained ground in recent years, showing promising results in oncological pathology diagnosis. These new methods have enabled the detection of subtle molecular profile alterations prior to any macroscopic morphological changes, thus providing a useful tool for early CRC detection. In the present review, we provide a summary of published studies applying SERS in CRC detection, along with our personal experience in using SERS in the diagnosis of different oncological pathologies, including CRC.

Flavonoids are metabolites of plants and fungus. Flavonoid research has been paid special attention to in recent times after the observation of their beneficial effects on the cardiovascular system. These favorable effects are exerted by flavonoids mainly due to their antioxidant properties, which result from the ability to decrease the oxidation of low-density lipoproteins, thus improving the lipid profiles. The other positive effect exerted on the cardiovascular system is the ability of flavonoids to produce vasodilation and regulate the apoptotic processes in the endothelium. Researchers suggested that these effects, including their anti-inflammatory function, are consequences of flavonoids’ potent antioxidant properties, but recent studies have shown multiple signaling pathways linked to them, thus suggesting that there are more mechanisms involved in the beneficial effect of the flavonoids on the human body. This review aims to present the latest data on the classification of these substances, their main mechanisms of action in the human body, and the beneficial effects on the physiological and pathological status of the cardiovascular system.

Early diagnosis based on screening is recognized as one of the most efficient ways of mitigating cancer-associated morbidity and mortality. Therefore, reliable but cost-effective methodologies are needed. By using a portable Raman spectrometer, a small and easily transportable instrument, the needs of modern diagnosis in terms of rapidity, ease of use and flexibility are met. In this study, we analyzed the diagnostic accuracy yielded by the surface-enhanced Raman scattering (SERS)-based profiling of serum, performed with a portable Raman device operating in a real-life hospital environment, in the case of 53 patients with gastrointestinal tumors and 25 control subjects. The SERS spectra of serum displayed intense bands attributed to carotenoids and purine metabolites such as uric acid, xanthine and hypoxanthine, with different intensities between the cancer and control groups. Based on principal component analysis-quadratic discriminant analysis (PCA-QDA), the cancer and control groups were classified with an accuracy of 76.92%. By combining SERS spectra with general inflammatory markers such as C-reactive protein levels, neutrophil counts, platelet counts and hemoglobin levels, the discrimination accuracy was increased to 83.33%. This study highlights the potential of SERS-based liquid biopsy for the point-of-care diagnosis of gastrointestinal tumors using a portable Raman device operating in a clinical setting.

Sarcopenia is defined as the age-related loss of skeletal muscle mass and decline of function. The causes of sarcopenia are multi-factorial. The diagnosis of sarcopenia should be considered in all older patients who present with declines in physical function, because of potential consequences for the development of frailty and disability. There are numerous techniques to assess muscle mass, muscle strength and physical performance. Treatment consists of nutritional (macro- and micronutrients) and physical activity (resistance exercise) regimens adapted to person. There is an emerging role for testosterone and anabolic steroids in severe sarcopenia.

Complex treatment involving removable articulated to fixed prostheses is indicated in extended edentulous areas, which represent clinical conditions more frequently encountered in elderly patients. A number of aspects must be considered in elderly patients before starting the therapy: physical and mental condition, self-care capacity , time and cost of treatment, predictability. In institutionalized elders, suffering of systemic diseases, the therapy of choice should be the least invasive and able to restore function at an acceptable level. Active healthy elders can be beneficiaries of complex prosthetic treatments involving many long sessions and difficult treatments.We present a case of a 74 year-old male with extended maxillary edentulous areas, in whom a complex prosthetic treatment was performed.

Brown tumors result from excess osteoclast activity and consist of collections of osteoclasts intermixed with fibrous tissue and poorly mineralized woven bone. They are secondary to hyperparathyroidism (HPT). Their incidence is higher in primary than in secondary hyperparathyroidism. We report a 69 years-old male, admitted in a state of confusion, lethargy and bedridden, with a pathological fracture of the femur caused by a brown tumor. The laboratory examination revealed a hypercalcemia (8.85 mEq/L), with high levels of ionized Ca (5.48 mEq/L), serum alkaline phosphatases (416 U/L) and serum parathormone (120 pg/mL). Ultrasound examination of the neck showed a large parathyroid tumor, probably corresponding to a carcinoma. A primary HPT was diagnosed. The patient was hydrated and high doses of diuretics and bisphosphonates were administered. After correction of serum calcium and neurologic symptoms, the patient was operated, performing an extensive resection of the tumor. The pathology report confirmed the diagnosis of parathyroid carcinoma.

Non-alcoholic fatty liver disease (NAFLD) is caused by fatty infiltration of the liver in the absence of alcohol consumption. The incidence of NAFLD in general population is 30-40%. NAFLD is considered by some authors to be the liver manifestation of the metabolic syndrome and by other authors is considered to be a separate entity. The pathogenesis of NAFLD and metabolic syndrome seems to have common pathophysiological mechanisms, with focus on insulin resistance as a key factor. Insulin resistance seems to explain the accumulation of triglycerides in the liver, being the main pathogenetic link involved in the onset and progression of NAFLD. The natural evolution is not well known, and there is some controversy about the progression from NAFL to NASH and fibrosis. Current data on epidemiology, pathophysiology and diagnostic supports the association of non-alcoholic fatty liver disease as a possible component in the cluster of metabolic syndrome. Clinical, experimental and epidemiological studies argue that NAFLD may be the hepatic manifestation of metabolic syndrome.

The current concept of quality of life reported to health status is described by patients in relation to personal expectations. These expectations vary over time and are influenced by the duration and severity of disease, the limitations of any kind, and family support. Quality of life is measured using individual questionnaires. These questionnaires are multidimensional and cover multiple aspects such as physical condition, emotional, social and cognitive status. Other aspects of the questionnaire refer to the individual's status in society and the perception of sickness. The purpose of this study was to estimate the quality of life of patients with allergic rhinitis and to establish the best treatment. To assess quality of life we used five symptoms score and visual analog scale. We have studied 92 cases with allergic rhinitis. Patients included in the study were between 6 and 18 years. Patients completed questionnaires that reflect quality of their life. Depending on the severity of symptoms patients were divided into two groups: patients with mild persistent allergic rhinitis (22%) and patients with moderate-severe persistent allergic rhinitis (78%).

Background: High blood pressure causes left ventricular hypertrophy, which is a negative prognostic factor among hypertensive patients. Aim: To assess left ventri- cular geometric remodeling patterns in patients with essential hypertension or with hypertension secondary to parenchymal renal disease. Material and Methods: We analyzed data from echocardiograms performed in 250 patients with essential hyper- tension (150 females) and 100 patients with secondary hypertension (60 females). The interventricular septum and the left ventricular posterior wall thickness were measured in the parasternal long-axis. Left ventricular mass was calculated using the Devereaux formula. Results: The most common remodeling type in females and males with essential hypertension were eccentric and concentric left ventricular hypertrophy (cLVH), respectively. Among patients with secondary arterial hypertension, cLVH was most commonly observed in both genders. The prevalence of left ventricular hyper- trophy was higher among patients with secondary hypertension. The left ventricular mass index and the relative left ventricular wall thickness were higher in males and also in the secondary hypertension group. Age, blood pressure values and the duration of hypertension, influenced remodeling patterns. Conclusions: We documented a higher prevalence of LVH among patients with secondary hypertension. The type of ventricular remodeling depends on gender, age, type of hypertension, blood pressure values and the duration of hypertension. (Rev Med Chile 2013; 141: 1520-1527).

Therapeutic adherence represents the extent to which the patient's behavior follows medical recommendations. It is a complex process that strongly influences the quality of life of the each and everyone. We performed a retrospective study that included 126 very old patients (≥ 80 years old). Patients' data were recorded in a database that contained demographic and clinical data and information about patient's current medication. Information about therapeutical adherence was collected for each person by way of a questionnaire, which consisted in verifying their knowledge about their diet and medication and comparing it with information from past medical records or family members. We found several factors that influence adherence to treatment: living in the urban area, the number of pills prescribed by the general practitioner and a strong familial and financial support. Fighting non-adherence should rely upon two complementary directions: the multidisciplinary medical approach and the telemonitoring and e-health systems.

The association between hepatic cirrhosis and arterial pulmonary hypertension is mentioned in the literature. The authors report the case of a patient with hepatic cirrhosis, who developed in time an arterial pulmonary hypertension with a fatal outcome. They discuss the pathogenesis of arterial pulmonary hypertension in patients with hepatic diseases, and the therapeutic options in these patients.
