Dynamics of the development of multiple follicles by early versus late hCG administration in ART program

Objective: To evaluate, in patients stimulated with recombinant FSH and GnRH antagonists, whether triggering the final maturation of oocytes affects IVF outcomes.

Study design: Five hundred and six IVF procedures were divided into three groups according to the timing of hCG administration: when at least 2 follicles reached the diameter of 17?mm, at least 2 follicles reached 18?mm and at least 2 follicles reached 20?mm. The main outcome was the number of mature oocyte that was the dependent variable of a multivariate model whose independents were, age, AFC, hCG timing, E2 levels at hCG day, number of follicles in different categories of dimension. Secondary endpoints were to compare fertilization, implantation and pregnancy rates in a multilevel multivariate model whose covariates were age, BMI, AFC, embryo quality and cause of infertility.

Results: Timing did not result a statistically significant factor influencing the number of oocytes collected, which was influenced by age, AFC, number of follicles between 12.1 and 15.9?mm and E2 levels. Implantation rate and pregnancy rate appear to be affected only by embryo quality.

Conclusion: The number of oocytes collected and the probability of pregnancy are not associated with the time of hCG administration.     

Alcohol, psoriasis, liver disease, and anti-psoriasis drugs

Over the last years, data have been accumulating regarding a possible association between alcohol and psoriasis. While it is still unclear whether alcohol misuse represents a true risk factor or merely an epiphenomenon of the cutaneous disease, a number of studies support the role of ethanol and its metabolites as triggering factors of psoriasis. A drinking habit also appears to exacerbate a preexisting psoriasis, and the magnitude of alcohol consumption may be related to both a higher incidence and severity of psoriasis. Evidence also shows that deaths from alcohol-related causes are significantly more frequent in patients with psoriasis than in normal controls. Alcohol consumption may adversely affect psoriasis through multiple mechanisms, such as increased susceptibility to infections, stimulation of lymphocyte and keratinocyte proliferation, and production of proinflammatory cytokines. Moreover, alcohol misuse can predispose to a greater risk of liver disease and potential drug interactions. Alcoholic and non-alcoholic liver diseases have both been found to be common in psoriatic patients. Tumor necrosis factor (TNF)-alpha, a key cytokine in psoriasis pathogenesis, has been found to have a crucial role in alcoholic hepatitis, and small preliminary studies have evaluated the effect of anti-TNF therapy in this condition. However, the use of anti-TNF-α drugs in alcoholic hepatitis is still controversial and needs to be further investigated. In this review, the relationship between alcohol and psoriasis will be reviewed and discussed, taking also into account recent findings related to liver disease and therapeutic implications.     

Compliance,Adherence and Concordance Differently Predict the Improvement of Uremic and Microbial Toxins in Chronic Kidney Disease on Low Protein Diet

Background. In medicine, “compliance” indicates that the patient complies with the prescriber’s recommendations, “adherence” means that “the patient matches the recommendations” and “concordance” means “therapeutic alliance” between patient and clinician. While a low protein diet (LPD) is a cornerstone treatment of chronic kidney disease (CKD), monitoring the actual performance of LPD is a challenge. Patients. Fifty-seven advanced CKD adult patients were enrolled and LPD prescribed. Compliance was evaluated through the normalized protein catabolic rate (nPCR), adherence by the dietitian by means of a 24-h dietary recall and concordance by the nephrologist during consultations. Traditional parameters as well as total p-Cresyl Sulphate (t-PCS), total Indoxyl Sulphate (t-IS) and Lipoprotein-associated phspholipase A₂ (Lp-PLA₂) were compared between adherent/not adherent and concordant/not concordant subjects at enrolment and after two months. Results. nPCR, blood urea nitrogen, cholesterol and triglycerides significantly decreased in all patients. t-PCS and t-IS decreased among adherent subjects. Lp-PLA₂, t-PCS, free-PCS and t-IS decreased among concordant subjects, while these increased in non-concordant ones. Conclusion. This study demonstrates that LPD may improve the control of traditional uremic toxins and atherogenic toxins in “adherent” and “concordant” patients. A comprehensive and multidisciplinary approach is needed to evaluate the compliance/adherence/concordance to LPD for optimizing nutritional interventions.     

Does Mediterranean Adequacy Index Correlate with Cardiovascular Events in Patients with Advanced Chronic Kidney Disease? An Exploratory Study

The Mediterranean Diet (MD) is a healthy dietary pattern, demonstrated to reduce the risk of cancer, diabetes, cardiovascular and neurodegenerative diseases, and early death. The Mediterranean Adequacy Index (MAI) is used to measure adherence to the MD in perspective studies in the general population and correlates with cardiovascular events. The aim of this study was to calculate the MAI among patients with advanced chronic kidney disease (CKD) and correlate it with traditional uremic, microbiota-derived, and proatherogenic toxins as well as nutritional status, quality of life, and cardiovascular events. A total of 60 adult patients with advanced CKD were enrolled and their MAI was calculated. According to the median value, patients were divided into lower (l-MAI, <1.80) and higher (h-MAI, ≥1.80) MAI groups. Biochemical parameters, microbiota-derived and proatherogenic toxins (p-Cresyl sulphate, Indoxyl-sulphate, and Lipoprotein-associated phospholipase A₂), nutritional status, quality of life, and cardiovascular events that occurred in the previous three years were recorded. The mean value of the MAI was 2.78 ± 2.86. The MAI was significantly higher in foreigners (median (IQR) 6.38 (8.98) vs. 1.74 (1.67), p < 0.001) and diabetic patients. The l-MAI and h-MAI groups had similar routinary blood, p-Cresyl-sulphate, Indoxyl-sulphate, and Lp-PLA₂ as well as nutritional status and quality of life parameters. The MAI was not associated with previous cardiovascular events and did not correlate with cardiovascular events in CKD patients. New and nephro-tailored indexes are warranted to evaluate nutritional therapy in CKD patients.

Does Additional Care Provided by a Consumer Self-Help Group Improve Psychiatric Outcome? A Study in an Italian Community-based Psychiatric Service

This study compares the two-year clinical and social outcome, the use of services and the direct costs of patients of the South-Verona Community Psychiatric Service who were members of a self-help group, with those who were not. Use of services and costs in the two years before the baseline were compared with those occurring two years after the baseline. Self-help subjects decreased their use of hospital stay as to number of admissions and days in hospital, with a reduction of costs; they were more satisfied as to work/education while non self-help matches presented an increase of unmet needs. Clinical and social outcome showed no significant difference. The findings suggest that consumer participation may possibly enhance the effects of psychiatric treatment on outcome.     

Validity of the minimal assessment of cognitive function in multiple sclerosis (MACFIMS) in the Italian population

Cognitive dysfunction involves 40–65 % of multiple sclerosis (MS) patients. It can be detected in all MS phenotypes from the early stages of the disease, and it tends to progress over time. Minimal Assessment of Cognitive Function in MS (MACFIMS) has been proved to be the most sensitive and comprehensive battery available for MS cognitive assessment in the English population. In Italy, MACFIMS applicability is limited in everyday clinical practice since the overall validity of this battery in the Italian MS population has never been demonstrated. The aim of this study was to translate/cross-culturally adapt and validate an Italian version of the MACFIMS. A total of 130 MS patients and 60 healthy controls (HCs) were enrolled and evaluated with an Italian version of the MACFIMS. All tests discriminated MS patients from HCs; according to the literature, approximately more than half of MS patients (70.8 %) exhibit cognitive impairment. Principal component analysis showed four distinct components: visual–spatial memory/processing speed, working memory, executive functions and verbal memory. Our study is the first to validate an Italian version of the MACFIMS. Several aspects of validity have been demonstrated: criterion and, partially, construct. Future work will investigate the longitudinal course of neuropsychological dysfunction in Italian MS patients using these measures.     

Diltiazem induces regulatory T cells in vitro by modulating human dendritic cell maturation

Diltiazem is a calcium channel antagonist that has been commonly associated with currently used immunosuppressants to prevent acute graft rejection in humans. In this study, we examined the possibility that diltiazem may affect human dendritic cell (DC) functions in response to lipopolysaccharide (LPS) stimulation and may induce the generation of DC with the capacity to generate CD4⁺ regulatory T cells (Tregs). Blood monocytes were cultured in the presence of diltiazem at the beginning of their differentiation process into DC. Monocyte‐derived DCs were stimulated with LPS, and DCs differentiated in the presence of diltiazem showed a decreased interleukin (IL)‐12 production and an enhanced IL‐10 production. When cultured with CD4⁺CD45RA⁺ they were able to enhance the CD4⁺Foxp3⁺ T‐cell population and to induce slowly proliferating T cells, which showed a significant increase of transforming growth factor (TGF)‐β production. These T cells suppress proliferation of activated autologous T cells, and we show that this effect is attributable to soluble factors, primarily to TGF‐β. Blockade of TGF‐β by specific monoclonal antibodies reversed this inhibitory effect. Herein, we provide new evidence that diltiazem‐conditioned monocyte‐derived DC induce T cells which acquire a regulatory phenotype and activity similar to those described for Tregs.
