    Abstract: The aim of the study is to quantify ventricular interactions by comparing tissue and spectral systolic echocardiographic parameters to allow the early identification of ventricular dysfunction. Clinical, paraclinical, electrocardiographic and echocardiographic evaluations were performed. Right ventricular hypertrophy was diagnosed in the M mode subcostal echocardiographic section. RV hypertrophy was defined by a right ventricular free wall thickness of ] 5 mm in diastole. We assessed the following RV and LV tissue and spectral systolic indices: apical systolic excursion of the lateral mitral ring (MAPSE), apical systolic excursion of the lateral tricuspid ring (TAPSE), left (Svs) and right (Svd) ventricular tissue systolic velocities, and RV and LV ejection times. We calculated the following to assess systolic ventricular interdependence: MAPSE/TAPSE, the normal value of which was considered as 0.66 � 0.14, and Svs/Svd, the normal value of which was considered as 0.76 � 0.21. The study group was compared to a control group with the same clinical features but without ventricular hypertrophy. Twenty-one patients were included in the study: 13 men (62%) and eight women (38%) with a mean age of 56 � 3.8 years. We compared the values between the study group and control group, with the following results: TAPSE = 20.4 � 0.9 vs. 24.1 � 0.76 and MAPSE/TAPSE = 0.74 � 0.06 vs. 0.75 � 0.04. MAPSE was comparable between the groups. Svs was comparable between the groups (0.09 � 0.01 vs. 0.12 � 0.02), whereas Svd was different between the groups (0.11 � 0.03 vs 0.16 � 0.03). Svs/Svd was 0.81 � 0.05 in the study group and 0.75 � 0.08 in the control group. LV ejection time was comparable between the two groups (299.8 � 23.6 ms vs. 303.3 � 28 ms), whereas, RV ejection time differed between the groups (275 � 17 ms vs. 245.5 � 28.5). Changes in TAPSE and MAPSE/TAPSE, in addition to Svd and Svs/Svd, are related to right ventricular dysfunction and suggest pathological changes in the interdependence mechanism of the ventricles in patients with RV hypertrophy. In addition, RV free wall thickness was strongly correlated with ventricular interdependence parameters, with the exception of MAPSE. Assessing these parameters and proportions in clinical practice will facilitate the early detection and appropriate treatment of right ventricular dysfunction.

    Abstract: The aim of this study was to investigate the acute cardiovascular hemodynamic effects of administration of a fixed dose of 130 mg of caffeine versus placebo in a sample of healthy young adults (N = 32, sex ratio 1/1), who were successively placed in four distinct positions (orthostatic before ingestion, orthostatic, supine and Trendelenburg vertical positions, after ingestion) on a gravitational inversion table. The experimental design was a single-center, parallel-group, double-blind, randomized, placebo-controlled clinical trial. Following the descriptive and inferential statistical processing of the data, a statistical significant pattern (p [0.05) of acute postural cardiovascular hemodynamic adaptation of the subjects was revealed, under the influence of caffeine versus placebo ingestion.

    Abstract: The effectiveness of pharmacological therapies is supported and guaranteed by medical protocols, which are the result of long-lasting experiments and scientific research, of course adapted to the level of competence and functional capacity of the healthcare provider. Besides pharmacological effectiveness, the therapeutic regimens should be evaluated from the point of view of economic efficiency, by assessing the financial impact of drug consumption, in correlation with other indicators specific to medical management. A retrospective comparative study of drug used in a surgical section with a capacity of 25 beds, from a county hospital is described. Study objective was to identify the relationship of influence and determination between costs with drugs and other economic and financial indicators and the use of services; objectively evaluate the effectiveness of the protocols used to limit the development of antibiotic resistance, avoiding polypharmacy and improving costs related to drug use, but especially to determine the existence of deviations from these and generating causes. The implementation of medical protocols has led to a decrease in drug costs. Tracking drug use is an effective tool to increase the quality of medical services by avoiding polypharmacy, therapeutic errors and preventing the development of antibiotic resistance. All these aspects are supported by the implementation of medical protocols and, thus, drug use can be appreciated as a valid indicator of their effectiveness and efficiency.

    Abstract: Purpose of the study: echocardiographic evaluation of the form of degenerative aortic stenosis (DAS) with preserved ejection fraction (EF) and low transvalvular gradient, in order to formulate the indication of valvular prosthesis as early as possible; retrospective observational study that includes patients admitted or sent for ambulatory evaluation by other medical services. The echocardiographic parameters used: systolic and diastolic indices, tissue and spectral, mitral and tricuspid veins, aortic orifice area, maximal aortic systolic velocity, maximal and medium aortic transvalvular gradient, myocardial mass index, volume of left atrium, left ventricular (LV) thickness. 42 patients with severe DAS and preserved EF, average age 71.7�3.85 years. Two groups were isolated: A - with increased gradient (22 patients) and B - with low gradient (20 patients). The gender distribution was comparable: women representing 33% in group A versus 30% in group B. The average age of women in both groups was higher than that of the men: in group A: 72�8 years in the case of women vs. 67�6 years in the case of men and in group B 72�3.5 years in women vs. 68�6 years in men. Apical displacement of the mitral ring: 14�2mm in lot A vs. 11�2mm in lot B. Myocardial mass index: 120 � 9g/m2 in lot A vs. 126 � 12g/m2 in lot B. Left ventricular filling ratio E/e�: 8�2 in lot A vs. 13�2 in lot B; maximum aortic systolic velocity: 4.3�0.9m/s in lot A vs. 3.1�0.8m/s in lot B; maximum gradient: 73.9�10mmHg in lot A vs. 37�12mmHg in lot B; aortic orifice area: 0.80�10.5 in lot A vs. 0.79�0.07 in lot B. Statistical analysis shows the Pearson correlation index r with the highest values of 95% at the significance threshold between the aortic orifice area and the valve opening (r=0.87), the ratio E/e� (r=-0.85) and diastolic thickness of the posterior wall of the aortic left ventricle (r = 0.78). Aortic stenosis with preserved ejection fraction and low gradient was more common in men. The filling ratio E/e� was increased (13 � 2) in group B, suggesting the increase of filling pressures of LV in patients with DAS and low transvalvular gradient. Tissue spectral systolic and longitudinal velocities were lower in group B, suggesting the onset of systolic LV dysfunction. The aortic valve opening and the E/e� ratio showed the highest correlation coefficient with the area of the aortic orifice in both groups. The myocardial mass index and the thickness of the walls of the LV cavity are similar in the two groups, suggesting that the reduction of the LV cavity through hypertrophy may not explain, at least in totality, the form of DAS with low gradient and preserved ejection fraction.

    Abstract: Diabetic foot is a current public health problem and a late consequence of diabetes. Morbidity and mortality are significant, seriously affecting the patient�s quality of life. Treatment of the diabetic foot is a long-lasting, highly resource-consumption process. Using negative pressure therapy leads to shorter hospitalization periods, better functional outcomes, significantly contributes to decreasing the number of amputations and improving patient�s quality of life. 49 year-old patient is hospitalized with necrotizing at right foot and shank, neglected type II diabetes. It is performed amputation of atypical necessity, right leg, transtarsal, open stump. After successive debridements, negative pressure therapy is installed for a period of 24 days. This favors the formation of the granular bed, the remission of the infection, allowing grafting. The graft is partially integrated and plantar reconstruction is performed with sural reversal flap. The local and functional results are satisfactory, with the flap viability and the possibility of moving with support on the right leg, preventing the amputation of the shank. Negative pressure therapy has a multitude of advantages, it is preferable to conventional therapies, and it can have higher costs, but accelerates healing and improves the quality of life of the patient.

    Abstract: The objective of the study was to analyze the characteristics of the patients with preserved ejection fraction heart failure (HfpEF) who develop hyponatremia, in relationship with the diabetes mellitus (DM). The current study is an observational retrospective one, that included 36 patients(25 women, 11 men), aged 66.6� 3.1 years, hospitalized for decompensated chronic heart failure, with a left ventricular ejection fraction ]40%. 33% (n=12) of the enrolled patients had hyponatremia, which was strong associated with DM (75% vs 17%, p[0.0005). In hyponatremic patients group was no association between DM and age, gendre, smoking, artrial hypertension, dyslipidemia, ejection fraction distribution or NTproBNP. As for medication at admission, we found an association of the presence of DM with betablockers(100% vs 67%, p[0.05) and with statins( 89% vs 67%, p[0.05). In our study, DM and non-DM patients with low serum sodium values and HfpEF have quite similar clinical profile, since the differences we found do not explain the high prevalence of DM in hyponatremic patients. As a conclusion, the presence of DM itself may explain the high prevalence of DM in hyponatremic patients, but is necessary to have larger studies with more variables included to assess HFpEF patients with DM and hyponatremia.

    Abstract: Antibiotherapy is the main determinant of Clostridium difficile infection due to the imbalance determined in the intestinal flora. Clostridium difficile infection can be considered a current public health problem, given the increased incidence, both as a nosocomial infection as well as at community level, by excessive, uncontrolled and unjustified use of antibiotics, high contagiousness, negative influence on health systems in the increased number of days of hospitalization and implicitly increased costs, and last but not least, the substantial deterioration of the quality of the patient�s life. The retrospective study over a 12-month period over a group of 106 patients revealed the following profile of the patient affected by Clostridium difficile infection: females, aged 66.75 � 15.66, from the urban area, hospitalized in the medical section, who had diarrhea more than 2 days after admission, but up to 28 days after this event, due to prolonged antibiotic therapy with ceftriaxone, associated with a gastric secretion inhibitor, on a background of multiple associated pathologies. It is very important for all health systems to control this phenomenon and this is only possible by applying effective measures to prevent the onset of CDI, of relapses and contamination, thus identifying the judicious use of antibiotics.
