RESUMO

Fermented dairy products have recently gained popularity due to their purported health benefits, nevertheless, their role in ageing remains uncertain. This narrative review aims to evaluate evidence from observational (prospective) and interventional studies on the potential benefits of fermented dairy product consumption for musculoskeletal and mental health in older adults. Additionally, it seeks to determine whether any observed benefits surpass those of non-fermented dairy products and to identify directions for future research. Prospective studies support either favourable or neutral associations of fermented dairy products with outcomes of musculoskeletal health or neutral associations with mental health outcomes, whilst it remains unclear if the benefits observed with fermented dairy products go beyond those of the non-fermented dairy foods. Few interventional studies suggest overall favourable effects of yogurt and cheese on musculoskeletal health in older adults but given their small number (N = 6) and heterogeneity, they do not allow a clear assessment or definitive recommendations for fermented dairy intake. Interventional studies reporting mental health outcomes are largely lacking for this age group (N = 1). Given the very limited evidence for the effectiveness of fermented dairy products, future well-designed prospective and randomized controlled trials are needed to better understand their benefits (especially compared to those of non-fermented dairy foods), their characteristics and the quantities required to offer protection against musculoskeletal and/or mental health ageing.

RESUMO

BACKGROUND: Real-world data in patients with moderate psoriasis treated with apremilast is limited. OBJECTIVES: To evaluate the effectiveness and safety of apremilast in bio-naïve patients with moderate psoriasis in real-world clinical settings. METHODS: This was a 52-week multicenter, observational, prospective study of adult outpatients with moderate psoriasis {[10% < body surface area < 20% or 10 < psoriasis area severity index (PASI) < 20] and 10 < dermatology quality of life index (DLQI) < 20} initiated on apremilast ≤7 days before enrollment. Missing data were imputed using the last observation carried forward method. RESULTS: A total of 287 eligible patients (median age: 54.2 years; median psoriasis duration: 9.8 years) were consecutively enrolled. At baseline, the median DLQI and PASI scores were 12.0 and 11.8, respectively. The 52-week DLQI ≤ 5 and PASI75 response rates were 68.3% and 61.0%. At 52 weeks, 70.8% and 72.7% of the patients shifted from moderate/severe/very severe to clear/minimal scalp and palmoplantar psoriasis involvement, respectively; the pruritus severity state improved in 67.2%. The 52-week Kaplan-Meier estimated drug continuation rate was 85.3%. The adverse drug reaction rate was 19.9%. CONCLUSIONS: Apremilast is a safe and effective treatment for bio-naïve patients with moderate psoriasis and specific psoriasis manifestations.

RESUMO

BACKGROUND: Apremilast is an oral phosphodiesterase-4 inhibitor indicated for patients with moderate-to-severe chronic plaque psoriasis and active psoriatic arthritis. OBJECTIVES: To examine the effectiveness of apremilast on Dermatology Life Quality Index (DLQI), Psoriasis Area and Severity Index (PASI) and nail, scalp and palmoplantar involvement, when administered prior to biologics. METHODS: This 52-week real-world study included biologic-naive adults with moderate psoriasis (psoriasis-involved body surface area 10% to <20%, or PASI 10 to <20 and DLQI 10 to <20). Apremilast was initiated ≤7 days before enrolment. Data from the first 100 eligible patients who completed 24 weeks (W24) of observation (or were prematurely withdrawn) are presented in this interim analysis using the last-observation-carried-forward imputation method. RESULTS: Eligible patients (mean age: 49.9 years; 71.0% males; median disease duration: 8.0 years) were consecutively enrolled between April and October 2017, by 18 dermatology specialists practising in hospital outpatient settings in Greece. Baseline DLQI (median: 12.0) and PASI (median: 11.7) scores improved (P < 0.001) at all postbaseline timepoints (Weeks 6, 16 and 24; W24 median decreases: 9.0 and 9.4 points respectively). At W24, DLQI ≤5, DLQI 0 or 1, and PASI-75 response rates were 63.0%, 25.0% and 48.0% respectively. The Nail Psoriasis Severity Index score in patients with baseline nail involvement (n = 57) decreased at all postbaseline timepoints (P < 0.001; W24 median decrease: 20.0 points). At W24, 50.0% and 51.7% of patients with baseline scalp (n = 76) and palmoplantar (n = 29) involvement respectively achieved postbaseline Physician's Global Assessment (PGA) score of 0 or 1 if baseline score was ≥3, or 0 if baseline score was 1 or 2. The adverse drug reaction rate was 21.0% (serious: 2.0%). CONCLUSIONS: These interim results indicate that through 24 weeks, apremilast improved quality of life and reduced disease severity in biologic-naive patients with moderate plaque psoriasis, while demonstrating safety consistent with the known safety profile.

RESUMO

Histological severity is often mandatory for the management of HBeAg-negative chronic HBV patients. We evaluated the performance of transient elastography (TE) in this setting. We included 357 untreated HBeAg-negative patients with ≥ 1 reliable liver stiffness measurement (LSM-kPa) by TE: 182 inactive carriers with HBV-DNA < 2000 (n = 139) or 2000-19 999 IU/mL (n = 43) and 175 patients with chronic hepatitis B (CHB). In carriers, HBV-DNA > 2000 and/or LSM > 6.5 were considered as biopsy indications. LSMs did not differ between carriers with low and high viremia, but were lower in carriers than in patients with CHB (5.8 ± 1.7 vs 9.0 ± 5.6, P < 0.001) offering moderate differentiation between these two groups (AUROC: 0.705). LSMs did not change significantly in carriers after 16 (12-24) months. In carriers with a liver biopsy, Ishak's staging scores were similar between cased with low and high viremia but higher in cases with LSM > 6.5 than ≤ 6.5 kPa. Moderate fibrosis (stages: 2-3) was detected in 0/10 carriers with only HBV-DNA > 2000 IU/mL, 2/10 (20%) carriers with only LSM > 6.5 and 5/10 (50%) carriers with both HBV-DNA > 2000 and LSM > 6.5 (P = 0.009). In patients with CHB, LSMs correlated significantly with grading and staging scores and offered excellent accuracy for ≥ moderate, ≥ severe fibrosis or cirrhosis (AUROC ≥ 0.919-0.950). TE can be helpful for the noninvasive assessment of HBeAg-negative chronic HBV patients. In conclusion, LSMs offer excellent accuracy for fibrosis severity in HBeAg-negative patients with CHB and can identify carriers with high risk of moderate fibrosis, which may be present in up to 35% of carriers with LSM > 6.5 kPa and 50% of carriers with LSM > 6.5 kPa and HBV-DNA > 2000 IU/mL.

RESUMO

BACKGROUND: Thyroglobulin (Tg) is used as a postoperative marker for the follow-up of patients with thyroid carcinoma, but there is no consensus regarding the value that may indicate possible recurrence. Aim. To evaluate Tg levels as a marker for recurrence of thyroid carcinoma. SUBJECTS AND METHODS: Demographics and survival of 80 patients who underwent total thyroidectomy for well-differentiated thyroid cancer were analysed and related to Tg levels. Tg measurements were performed when patients were euthyroid, after completion of treatment. RESULTS: The median Tg value was 1.3 ng/ml. Higher values were found in males, high-risk patients and patients with recurrent disease. Using the median Tg value as cut-off, patients were divided into two groups (group I ≤1.3 ng/ml and group II >1.3 ng/ml). There was a significant correlation between values >1.3 ng/ml and recurrence. When survival was related to Tg values, there was a tendency towards worse prognosis in group II. The best predictive cut-off value for recurrence was found to be 1.3 ng/ml, which had a sensitivity of 77% and a specificity of 57%. CONCLUSIONS: Although low, a cut-off Tg level of 1.3 ng/ml represents a simple indication for further investigation in patients receiving thyroxine after completion of treatment for thyroid cancer, in the absence of measurement of anti-Tg auto-antibodies.

RESUMO

To date, no research has explored the effects of low energy availability on cognitive performance using dietary and exercise regimens relevant to athletes. Twenty female participants (10 eumenorrheic, 10 oral contraceptive [OC] users) completed three 3-day conditions: 1) controlled-balanced energy availability without exercise (BAL; 45 kcal·kg lean body mass [LBM]-1·day-1); 2) diet-induced low energy availability without exercise (DIET; 15 kcal·kg LBM-1·day-1); and 3) exercise-induced low energy availability (EX; 15 kcal·kg LBM-1·day-1, including 30 kcal·kg LBM-1·day-1 treadmill running at 70% maximal oxygen uptake). A cognitive test battery was completed before and after each 3-day condition. Mental rotation test accuracy improved in the BAL condition, but there was a decline in accuracy in the EX condition (BAL, +2.5%; EX, -1.4%; P = 0.042, d = 0.85). DIET (+1.3%) was not different to BAL or EX (P > 0.05). All other measures of cognitive performance were not affected by condition (P > 0.05) and OC use did not affect cognitive responses (P > 0.05). Accuracy in the mental rotation test was impaired when low energy availability was induced through increased exercise energy expenditure. All other aspects of cognition were unaffected by 3 days of low energy availability through diet or exercise. OC use did not mediate the effect of low energy availability on cognition. Novelty: Cognitive function was not affected by 3 days of diet-induced low energy availability. Only spatial awareness was impaired during 3 days of exercise-induced low energy availability. Reproductive hormones affected spatial awareness independent of energy availability.

RESUMO

AIM: The aim of this study was to evaluate epidemiology and survival of patients with well-differentiated thyroid cancer (WTC) treated with total thyroidectomy (TT) in the area of Thrace, Northern Greece. METHODS: The study was conducted on 80 patients who underwent total thyroidectomy from January 1985 to December 2004 for WTC. Patients' medical records and demographics, including age, sex, histological type (papillary, follicular, mixed type papillary-follicular, Hurthle), stage according to TNM staging, coexistence or future postoperative occurrence of local recurrence or distal metastases and overall and specific survival were analyzed and survival rates were calculated. RESULTS: Papillary carcinoma was found in 56.3% and follicular in 43.8%. Statistical analysis revealed significant correlation of male gender with the high-risk population (P = 0.017), follicular carcinoma with high-risk population (P < 0.0001) and high-risk population with local recurrence or metastatic disease (P < 0.0001). Overall year, 5-year and 10-year survival were 100%, 94% and 91.8% respectively. Further analysis showed a significant reduction in survival regarding to age > 45 years (P = 0.03), follicular type (P = 0.009), high-risk population (P = 0.008), presence of local recurrence or metastatic disease (P < 0.0001) and not significant correlation with male gender (P = 0.086). CONCLUSION: In conclusion, total thyroidectomy should be the surgical treatment of choice in all cases with WTC, especially in male patients > 45 years of age since they have a higher frequency of advanced malignant disease at presentation, a fact that affects prognosis. Patients must be accurately categorized postoperatively, and follow-up must be personalized, in order to diagnose recurrence as early as possible.

RESUMO

AIM: To study the frequency of multifocality in well-differentiated non-medullary thyroid carcinomas and correlate it with various epidemiological factors, as well as with patients' survival. PATIENTS AND METHODS: A retrospective study was conducted on 80 patients who underwent total thyroidectomy from January 1985 to December 2004 in the First Department of Surgery of University General Hospital of Alexandroupolis, Democritus University of Thrace, Greece, for well-differentiated non-medullary thyroid cancer (papillary and follicular). Patients' medical records and demographics, including age, gender, histological type (papillary, follicular), multiple foci of tumors, overall and specific survival were analyzed. RESULTS: Multifocality was established in 17/80 patients (21,25%). Multifocal tumors were found in 4/20 male patients (20%) and 13/60 female ones (21,67%), percentages which are almost identical. Increased rates of multifocal tumors were found in the age groups of 20-29, 30-39 and 70-79 years old, while low rates were documented in the age groups of 0-9, 10-19 and 60-69 years old. Follicular tumors had a 20% rate, similar to papillary tumors (22,2%), and an impressive multifocal rate of mixed papillary-follicular neoplasms (75%) was found. Finally, survival was not found to be influenced by the multifocality of the tumor, under the prerequisition that total thyroidectomy is applied. CONCLUSIONS: Multifocality should not be considered as a "privilege" of papillary thyroid tumors, but as a privilege of thyroid carcinomas in general. If total thyroidectomy is applied in all benign and malignant thyroid diseases, the presence of multiple foci does not affect the prognosis and the survival of the patients.

RESUMO

Although, several recent greenhouse studies are beginning to address the uptake of pharmaceuticals and personal care products (PPCPs) by a variety of crops, few studies have assessed the effects of exposure to complex, realistic wastewater effluents on uptake. Hence, in this study, a greenhouse experiment was conducted in order to study the interactions occurring exclusively between PPCPs in soil, and in the edible plant part of beets (Beta vulgaris) after exposure to treated wastewater effluent. According to the findings, the interactions between the pharmaceuticals caffeine (CFN) with bisoprolol (BSP), carbamezapine (CMZ), clarithromycin (CMC), metoprolol (MPL), sulfamethoxazole (SMX), and trimethoprim (TMP) occurring in soil were almost 99% synergistic; it was noted variability in the interactive capacity of the pharmaceuticals; the concentrations of pharmaceuticals which measured did not affect unfavorably beet yield; interactions between the PPCPs via the PPCPs contribution in plant and soil affect the qualitative and quantitative characteristics of the beets.

RESUMO

This study describes the screening of 13 commercially-available plant extracts for pharmacological activity modulating vascular function using an endothelial cell model. A French maritime pine bark extract (FMPBE) was found to have the greatest effect upon nitric oxide availability in control (181% ± 36% of untreated cells) and dysfunctional cells (132% ± 8% of untreated control cells). In healthy volunteers, the FMPBE increased plasma nitrite concentrations 8 h post-consumption compared to baseline (baseline corrected median 1.71 ± 0.38 (25% IQR) and 4.76 (75% IQR) µM, p < 0.05). This was followed by a placebo-controlled, healthy volunteer study, which showed no effects on plasma nitrite. It was confirmed that different batches of extract had been used in the healthy volunteer studies, and this second batch lacked bioactivity, assessed using the in vitro model. No difference in plasma catechin levels was seen at 8 h following supplementation between the studies (252 ± 194 nM versus 50 ± 64 nM, p > 0.05), however HPLC-UV fingerprinting showed that the new batch had a 5-15% in major constituents (including procyanidins A2, B1 and B2) compared to the original batch. This research describes a robust mechanism for screening bioactive extracts for vascular effects. It also highlights batch variability as a significant limitation when using complex extracts for pharmacological activity, and suggests the use of in vitro systems as a tool to identify this problem in future studies.

RESUMO

Trichoepitheliomas are benign skin tumors with follicular differentiation that present most commonly as solitary lesions. They can also present as multiple centrofacial papules due to several mutations in the CYLD gene. Multiple unilateral trichoepitheliomas in a linear or dermatomal distribution may rarely be seen. Herein, we report a case of multiple unilateral trichoepitheliomas on the face of a healthy 34-year-old woman of Caucasian origin.

RESUMO

A greenhouse experiment was conducted, using a randomized block design, including twelve heavy metal (Mn, Zn, Cu, Cd, Co, Cr, Ni, Pb) mixture treatments, with each metal participating in the treatment with 0, 2, 4, 6, 8, 10, and 12 mg/kg, respectively. Common beet (Beta vulgaris L.) was chosen as test plant. The plants were irrigated with treated municipal wastewater taken from the Wastewater Treatment Plant of the town of Amaliada, N.W., Peloponnese, Greece. The experiment aimed at studying the interactions between heavy metals and macro-microelements, and pharmaceuticals and personal care products (PPCPs). The basic scope was to shed some light on the potential environmental implications, of these interactions on the soil PPCPs for a more effective monitoring of these emerging contaminants in the plants and soil continuum. It was found that the PPCPs have a very high potential interactive capacity, having interacted with all the studied metals, and metalloids, as well as with plant macro elements (P, and K). The uptake of PPCPs by plants was statistically significantly related with their respective content in the soil. The general inference is that the interactive relations between heavy metals, macro-, microelements, and emerging contaminants, being mainly antagonistic, which contribute to the decrease the uptake of soil PPCPs.

RESUMO

Naturally Occurring Radionuclide Materials (NORM) such as fertilizers, agricultural soils fertilized and wheat grain cultivated at those soils were studied regarding the radiation hazard to the public and workers. Activity of 238U, 226Ra, 232Th and 40K was measured hermitical sealing the marinelli beaker using the Stopaq FN 2100L material that prevent 222Rn escape from the baker. The phosphate fertilization of soil did not affect natural radioactivity in comparison with non-fertilized soils and also did not affect natural radioactivity of wheat grain cultivated since only 40K was measured. The high mean value of Dair 211 nGy h-1 for fertilizers compared to soils fertilized 53 nGy h-1 highlights the raising concern about radioprotection of workers occupied with tasks involving fertilizers. The maximum external dose rate 1.15 mSv y-1 calculated for truck drivers involved to transportation section is similar to annual external effective dose limit 1 mSv. Real concerns rise for workers in the fertilizers storage and supply department since the maximum dose rate estimated is 1.98 mSv y-1, while the mean value is 0.89 mSv y-1.

RESUMO

BACKGROUND: Bone involvement represents a common symptom at diagnosis in children with acute lymphoblastic leukemia, and its prognostic value is not entirely clarified. The aim of this study was to evaluate bone involvement at diagnosis in children with acute lymphoblastic leukemia as a predictive factor and to correlate its presence with other demographic, clinical, and laboratory findings. METHODS: We retrospectively reviewed the medical records of 97 children with acute lymphoblastic leukemia diagnosed from January 2005 to December 2014. The mean age of patients was 5.7 years, and 83 (85.6 %) of them were diagnosed with B-acute lymphoblastic leukemia. RESULTS: Among the 97 children, 46 (47.4 %) reported bone involvement at the time of diagnosis. Among children with B-acute lymphoblastic leukemia 43/83 (51.8 %) reported bone involvement, while among children with T-acute lymphoblastic leukemia only 3/14 (21.4 %) (p =0.04). Bone involvement was registered more frequently among males (30/59; 50.8 %) in comparison to females (16/38; 42.2 %) (p =0.414). The mean white blood cell count at diagnosis was lower among children with bone involvement (109,800/mm3 vs. 184,700/mm3) (p =0.092). The mean age of patients with bone involvement was four years, which differs significantly from those without bone involvement (p =0.029). Moreover, children with bone involvement at diagnosis were prednisone "good responders" (79.5 %) when compared with those without bone involvement (58.8 %) (p =0.046). Additionally, mean serum phosphate values were higher at diagnosis among children with bone involvement (5.3 mg/dl vs. 4.8 mg/dl, p =0.035). CONCLUSIONS: The presence of bone involvement at diagnosis is related with immunophenotype of B-acute lymphoblastic leukemia, lower mean age, lower mean white blood cell count and good prednisone response. According to presented data, we conclude that the presence of bone involvement at diagnosis represents a positive predictive factor for outcome/survival. Hippokratia 2016, 20(3): 227-230.

RESUMO

In the present study, carrageenan microparticles were synthesized using spray-drying method and used as biosorbents for the removal of pharmaceutical compounds. The cross-linking reaction of iota-carrageenan (iCAR) and kappa-carrageenan (kCAR) with glutaraldehyde (GLA) at different concentrations (2.5% or 5% (w/w), mass of GLA per mass of CAR) was studied (iCAR/GLA2.5, iCAR/GLA5, kCAR/GLA2.5, kCAR/GLA5). The physicochemical properties of the novel cross-linked polymers were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Swelling studies were in accordance with the polymer properties, showing the lowest swelling degree (19%) by using the iCAR/GLA5 microparticles. The optimal kCAR/GLA5 microparticles were successfully employed for the removal of Metoprolol (MTPL) from aqueous samples. The adsorption capacity of the adsorbents was investigated using a batch adsorption procedure and the kinetics and thermodynamics of the adsorption process were further investigated. It was found that the adsorption isotherms agree well with the Langmuir-Freundlich model. The maximum adsorption capacity (Qm) was achieved in pH 6, whereas an increase of Qm was observed increasing the temperature (from 109 at 20°C to 178 mg/g at 40°C). Kinetic studies showed that the adsorption process on iCAR/GLA5 microparticles followed pseudo-second-order rate mechanism. Finally, a new phenomenological model of the adsorption process was proposed in order to extract information on the relevant sub-processes.

RESUMO

Twenty-three children with autism and two control groups completed an attention battery comprising three versions of the continuous performance test (CPT), a digit cancellation task, the Wisconsin Card Sorting Test (WCST), and two novel, computerized tests of shifting attention (i.e., the Same-Different Computerized Task and the Computerized Matching Task). Children with autism could focus on a particular stimulus and sustain this focus as indicated by their performance on the digit cancellation task and the CPT. Their performance on the WCST suggested problems in some aspects of shifting attention (i.e., disengaging attention). The autism group performed as well as controls on the Same-Different Computerized Task, however, that required successive comparisons between stimuli. This implies that they could, in fact, shift their attention continuously. In addition, they did not differ from controls on the Computerized Matching Task, an analog of the WCST, suggesting that they do not have a general deficit in shifting attention.

RESUMO

Liposarcomas are malignant tumors derived embryologically from mesodermal tissues. An unusual site of presentation is the spermatic cord, presenting as an inguinal or scrotal mass. We report a rare case of a liposarcoma of the spermatic cord, mimicking a testicular tumor. The patient was operated, and an orchidectomy, including the tumor, was performed. To our knowledge, there are about 185 similar cases reported in the literature.

RESUMO

OBJECTIVE: To determine the cost-effectiveness of vaccination against herpes zoster (HZ) and post-herpetic neuralgia (PHN) in individuals aged 60 years and older in Belgium. METHODS: A Markov model was developed to compare the cost-effectiveness of vaccination with that of a policy of no vaccination. The model estimated the lifetime incidence and consequences of HZ and PHN using inputs derived from Belgian data, literature sources, and expert opinion. Cost-effectiveness was measured by the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life-year (QALY) gained. RESULTS: Vaccination in individuals aged 60 years and older resulted in ICERs of €6,799 (third party payer perspective), €7,168 (healthcare perspective), and €7,137 (societal perspective). The number needed to vaccinate to prevent one case was 12 for HZ, and 35 or 36 for PHN depending on the definition used. Univariate sensitivity analyses produced ICERs of €4,959-19,052/QALY; duration of vaccine efficacy had the greatest impact on cost-effectiveness. Probabilistic sensitivity analysis showed at least a 94% probability of ICERs remaining below the unofficial €30,000 threshold. DISCUSSION: Key strengths of the model are the combination of efficacy data from a pivotal clinical trial with country-specific epidemiological data and complete sensitivity analysis performed. Main limitations are the use of non country-specific PHN proportion and non Belgian disease-specific utilities. Results are comparable with those recently published. CONCLUSIONS: HZ vaccination in individuals aged 60 years and older would represent a cost-effective strategy in Belgium.

RESUMO

Prostate cancers frequently metastasize to the skeleton, and it has been hypothesized that this environment selectively supports the growth of these tumours. Specifically there is strong evidence that interactions between tumour cells and BMSCs (bone marrow stromal cells) play a major role in supporting prostate cancer growth and survival in bone. Here, we examine factors shown to be secreted by BMSCs, such as IGFs (insulin-like growth factors) and IL-6 (interleukin 6), shown to promote prostate cancer cell proliferation and to potentially replace the requirement for androgens. In addition we discuss another factor produced by BMSCs, osteoprotegerin, which may promote tumour cell survival by suppressing the biological activity of the pro-apoptotic ligand TRAIL (tumour-necrosis-factor-related apoptosis-inducing ligand).
