RESUMO

The primary goal of this study was to generate different kinds of functional products based on carrots that were supplemented with lactic acid bacteria. The fact that carrots (Daucus carota sp.) rank among the most popular vegetables in our country led to the convergence of the research aim. Their abundance of bioactive compounds, primarily polyphenols, flavonoids, and carotenoids, offers numerous health benefits. Among the obtained products, the freeze-dried carrot powder (FDCP) variation presented the highest concentrations of total carotenoids (TCs) and ß-carotene (BC) of 26.977 ± 0.13 mg/g DW and 22.075 ± 0.14 mg/g DW, respectively. The amount of total carotenoids and ß-carotene significantly increased with the addition of the selected lactic acid bacteria (LAB) for most of the samples. In addition, a slight increase in the antioxidant activity compared with the control sample for the FDCP variant, with the highest value of 91.74%, was observed in these functional food products. The content of polyphenolic compounds varied from 0.044 to 0.091 mg/g DW, while the content of total flavonoids varied from 0.03 to 0.66 mg/g DW. The processing method had an impact on the population of L. plantarum that survived, as indicated by the viability of bacterial cells in all the analyzed products. The chromatographic analysis through UHPLC-MS/MS further confirmed the abundance of the bioactive compounds and their corresponding derivatives by revealing 19 different compounds. The digestibility study indicated that carotenoid compounds from carrots followed a rather controlled release. The carrot-based products enriched with Lactobacillus plantarum can be considered newly functional developed products based on their high content of biologically active compounds with beneficial effects upon the human body. Furthermore, these types of products could represent innovative products for every related industry such as the food, pharmaceutical, and cosmeceutical industries, thus converging a new strategy to improve the health of consumers or patients.

RESUMO

(1) Background: Acute kidney injury (AKI) is a serious complication of hematopoietic stem cell transplantation (HSCT). (2) Methods: The aim was to identify the incidence, severity, and risk factors for AKI during the first 100 days after allo-HSCT; we performed a prospective observational study on 135 consecutive patients. (3) Results: The mean age was 38.3 ± 11.9 years (50.6% females), AKI developed in 93 patients (68.9%), the median time of appearance was 28 days, and the mean serum creatinine at the time of AKI was 1.8 ± 0.8 mg/dL. A total of 36 (38.7%) patients developed stage 1 AKI, 33 (35.5%) patients developed stage 2, and 24 (25.8%) patients developed stage 3; eight (8.6%) patients required temporary hemodialysis, and the mortality rate in these patients was 87.5%. Death was twice as frequent in the AKI subgroup, without statistical significance. Cyclosporine overdose (HR = 2.36, 95% CI: 1.45-3.85, p = 0.001), tacrolimus overdose (HR = 4.72, 95% CI: 2.22-10.01, p < 0.001), acute graft-versus-host disease (aGVHD) (HR = 1.96, 95% CI: 1.13-3.40, p = 0.01), and CRP level (HR = 1.009, 95% CI: 1.007-1.10, p < 0.001) were independent risk factors for AKI. Sepsis (HR = 5.37, 95% CI: 1.75-16.48, p = 0.003) and sinusoidal obstruction syndrome (HR = 5.10, 95% CI: 2.02-12.85, p = 0.001) were found as independent risk factors for AKI stage 3. (4) Conclusions: AKI occurs with high incidence and increased severity after allo-HSCT. Careful monitoring of calcineurin inhibitors and proper management of sepsis may reduce this risk.

RESUMO

The current approach to flexor tendon injuries is complex and is no longer limited to suturing techniques. Strategies for improving hand function currently include rehabilitation protocols, appropriate suturing materials and techniques, changing the gliding surface by using lubricants and providing growth factors. One product, originally used in spinal surgery, has been shown to be effective in preventing postoperative adhesions. It is a combination of carboxymethylcellulose and polyethylene oxide-Dynavisc® (FzioMed, Inc.). The aim of the present study was to test the effect of Dynavisc® on acute injuries of the intrasynovial flexor tendons in the prevention of postoperative adhesions and the improvement of functional results. The study was performed on 20 Wistar rats distributed in two groups. The control group, represented by 10 rats, in which after the reconstruction of the flexor tendon, the peritendinous area was injected with saline solution and the study group, in which the peritendinous area was injected with a single administration of the lubricating gel, Dynavisc® (carboxymethylcellulose and polyethylene oxide). At 4 and 12 weeks, the rats were sacrificed and tissue biopsy consisted of tendon fragments and adjacent tissue. The evaluation of the results was performed by measuring the adhesion score and observing histological parameters. The presence of important adhesions was found in the control group compared with the group treated with Dynavisc®, where a supple and smooth tendon, with significantly fewer adhesions were found. The differences between the two groups were significant, thus indicating the efficiency of the lubricant in preventing adhesions. This study supported the important role of Dynavisc® in the regeneration of the tendon and the peritendinous structures, by limiting aberrant fibrous proliferation in the regeneration process and helping to build a peritendinous space.

RESUMO

BACKGROUND: Kidney involvement is a frequent complication of systemic lupus erythematosus (SLE) and kidney biopsy is essential in differentiating lupus nephritis (LN) from thrombotic microangiopathy (TMA) secondary to antiphospholipid autoantibodies (aPL). Association between antiphospholipid syndrome (APS) and acquired hemophilia due to inhibitors was very rarely described in SLE patients. CASE PRESENTATION: We present the case of a 61-year-old male diagnosed with SLE who acquired deficiency of clotting factor VIII due to circulating inhibitors, admitted for acute kidney injury (AKI), microangiopathic hemolytic anemia, thrombocytopenia, and diplopia. Kidney biopsy showed TMA due to APS, but no signs of LN. Head computed tomography identified low dense areas in the white matter, suggesting small blood vessels' involvement. A diagnosis of probable catastrophic antiphospholipid syndrome (CAPS) was established and treatment with low molecular weight heparin, intravenous methylprednisolone, plasmapheresis, and rituximab was initiated, followed by resolution of AKI, diplopia, and TMA with complete depletion of CD19+B-lymphocytes (CD19+B-Ly) after one month. We further review the current knowledge regarding pathogenesis and management of CAPS in SLE patients. CONCLUSIONS: Targeted therapy was possible after kidney biopsy, improving renal and general prognosis. CD19+B-Ly repopulation preceded biological relapse, so monitoring of CD19+B-Ly may serve as a tool to predict relapses and guide rituximab therapy.

RESUMO

OBJECTIVES: Body composition assessment in chronic obstructive pulmonary disease (COPD) is important, as weight loss and muscular wasting are responsible for low exercise capacity in these patients, and low body mass index (BMI) and fat free mass index (FFMI) are important prognostic factors. Our study aims were: (a) to describe body composition in COPD patients referred to a pulmonary rehabilitation center in Bucharest; (b) to examine the relationships between body composition and disease severity (bronchial obstruction, exercise capacity, quality of life); (c) to test if segmental wasting of lower limbs muscle mass (measured by segmental body composition analysis) correlates with decreased exercise capacity. MATERIAL AND METHODS: We studied 36 consecutive COPD patients referred to our clinic for pulmonary rehabilitation. Patients performed pulmonary function tests, six minutes walking test (6MWT), and health status was evaluated with COPD Assessment Test (CAT). Body composition measurements were performed by direct segmental multi-frequency bioelectrical impedance analysis (BIA). OUTCOMES: This study offers the first data on body composition of Romanian COPD patientsThe prevalence of nutritional depletion (defined by low BMI and/or low FFMI) among our COPD patients was 22.2%. Mean FFMI was significantly lower in normal or underweight patients versus overweight or obese patients. Patients with low FFMI had lower exercise capacity at the 6MWT and higher CAT scores than patients with normal FFMI.Depending on the BMI and FFMI values the patients were divided in four categories: normal, semistarvation, sarcopenia and cachexia. The group of patients with sarcopenia (low FFMI and normal BMI) had the lowest mean MIP (Maximal Inspiratory Pressure), the lowest mean 6MWD (six minutes walking distance) and the higher CAT mean scores among all groups. Exercise capacity was significantly lower in muscular depleted patients (with low skeletal muscle mass index - SSMI). MIP correlated significantly with FFMI and SMMI. No correlations were found between parameters of body composition and FEV1 or CAT. Segmental body composition assessment revealed that unbalanced upper/lower skeletal muscle mass is associated with a lower exercise capacity as measured by 6WMT. CONCLUSIONS: This study offers the first data on body composition of Romanian COPD patients. The prevalence of nutritional depletion is similar to that found in other European studies. No significant correlations were found between FFMI and severity of the disease (bronchial obstruction, distance walked, CAT score). FFMI and SSMI correlated significantly with MIP. Sarcopenic patients had the lowest mean 6MWD, the lowest mean MIP and the highest CAT mean scores. SMMI significantly correlated with 6MWD. Segmental body composition assessment of revealed that "unbalanced" patients had lower results at 6MWT. These results show that body composition evaluation is useful for the assessment of COPD patients referred to pulmonary rehabilitation and should be routinely performed.

RESUMO

Thyroid hormones have many effects on the heart and vascular system. Although cardiac output is reduced in hypothyroidism, heart failure is relatively rare because there is a lower demand for peripheral oxygen delivery. Hypothyroidism may also result in accelerated atherosclerosis and coronary artery disease. We report the case of a 55-year-old man with severe heart failure associated with severe longstanding untreated hypothyroidism. The patient was admitted for shortness of breath and chest pain. On presentation, signs and symptoms of severe hypothyroidism and heart failure were noticed. The electrocardiogram showed sinus bradycardia and ischemia. Thyroid stimulating hormone was extremely elevated and thyroid hormone levels were undetectable. A cardiac ultrasonography exam revealed abnormalities of the left ventricular dimensions and function consistent with dilated cardiomyopathy. Coronary angiography showed severe multivessel disease. Coronary by-pass was deemed necessary, but surgery was postponed because of severe heart failure. After an increasingly downhill clinical course, the patient died, eight month after his initial presentation, owing to severe heart failure. This patient represents an example of an overlooked diagnosis of severe hypothyroidism, rarely encountered nowadays, leading to dramatic consequences.
