Molecular profile of sensitization in subjects with short occupational exposure to latex

Objectives: We examined the prevalence of latex allergy in subjects with occupational exposure to latex allergens for less than 5 years, determining the disease spectrum in symptomatic workers. We identified the most frequent molecular allergens by Immuno- CAP (ICAP), correlating the findings with skin prick test (SPT) results. Material and Methods: Seven hundred twenty-three healthcare students using latex gloves on a regular basis were invited to participate in a baseline questionnaire screening. An ICAP serum test was performed only when a possible latex allergy was indicated by the questionnaire. Results: The total number of participants responding to the baseline survey was 619. Glove-related symptoms were indicated by 4% (N = 25) of the students. The most common symptom was contact dermatitis (N = 18, 72%). In 12 subjects, ICAP revealed a real sensitization to latex, with a recombinant latex allergen profile showing a high frequency for rHev b 6.01 specific immunoglobulin E (sIgE) (N = 9, 67%). In these individuals, skin symptoms were more prevalent than other types (88%). Conclusions: The combined positivity for rHev b 6.01, rHev 8 and rHev b 5 determined by ICAP identified 92% of latex-allergic subjects with short-term exposure to latex

Prospective validation of the CLIP score: a new prognostic system for patient with cirrhosis and hepatocellular carcinoma

Prognosis of patients with cirrhosis and hepatocellular carcinoma (HCC) depends on both residual liver function and tumor extension. The CLIP score includes Child-Pugh stage, tumor morphology and extension, serum alfa-fetoprotein (AFP) levels, and portal vein thrombosis. We externally validated the CLIP score and compared its discriminatory ability and predictive power with that of the Okuda staging system in 196 patients with cirrhosis and HCC prospectively enrolled in a randomized trial. No significant associations were found between the CLIP score and the age, sex, and pattern of viral infection. There was a strong correlation between the CLIP score and the Okuda stage, As of June 1999, 150 patients (76.5%) had died. Median survival time was 11 months, overall, and it was 36, 22, 9, 7, and 3 months for CLIP categories 0, 1, 2, 3, and 4 to 6, respectively. In multivariate analysis, the CLIP score had additional explanatory power above that of the Okuda stage. This was true for both patients treated with locoregional therapy or not. A quantitative estimation of 2-year survival predictive power showed that the CLIP score explained 37% of survival variability, compared with 21% explained by Okuda stage. In conclusion, the CLIP score, compared with the Okuda staging system, gives more accurate prognostic information, is statistically more efficient, and has a greater survival predictive power. It could be useful in treatment planning by improving baseline prognostic evaluation of patients with RCC, and could be used in prospective therapeutic trials as a stratification variable, reducing the variability of results owing to patient selection

Information content of dendritic spines after motor learning

Dendritic spines, small protrusions emerging from the dendrites of most excitatory synapses in the mammalian brain, are highly dynamic structures and their shape and number is continuously modulated by memory formation and other adaptive changes of the brain. In this study, using a behavioral paradigm of motor learning, we applied the non-linear analysis of dendritic spines to study spine complexity along dendrites of cortical and subcortical neural systems, such as the basal ganglia, that sustain important motor learning processes. We show that, after learning, the spine organization has greater complexity, as indexed by the maximum Lyapunov exponent (LyE). The positive value of the exponent demonstrates that the system is chaotic, while recurrence plots show that the system is not simply composed by random noise, but displays quasi-periodic behavior. The increase in the maximum LyE and in the system entropy after learning was confirmed by the modification of the reconstructed trajectories in phase-space. Our results suggest that the remodeling of spines, as a result of a chaotic and non-random dynamical process along dendrites, may be a general feature associated with the structural plasticity underlying processes such as long-term memory maintenance. Furthermore, this work indicates that the non-linear method is a very useful tool to allow the detection of subtle stimulus-induced changes in dendritic spine dynamics, giving a key contribution to the study of the relationship between structure and function of spines

Assessment of Quality of Life and Urinary and Sexual Function After Radical Hysterectomy in Long-Term Cervical Cancer Survivors

Aims: The aim of this study was to evaluate long-term quality of life and urinary and sexual function in long-term cervical cancer survivors previously treated with radical hysterectomy (RH) type C2/type III. Methods: All patients who presented at Campus Bio-Medico of Rome for RH type C2/type III for cervical cancer were considered eligible for this retrospective study protocol. We included exclusively patients with complete response to primary treatment with at least 36 months of follow up. Included subjects were interviewed with the European Organization for Research and Treatment of Cancer QLQ-CX24 Questionnaire, European Organization for Research and Treatment of Cancer QLQ-C30, and an Incontinence Impact Questionnaire 7. Results: From January 2004 to June 2014, 251 patients affected by locally advanced cervical cancer were treated at Campus Bio-Medico of Rome treated with type C2/type III RH. At time point of March 2017, 90 patients were included with a mean age of 55.6 ± 8.5 years. The questionnaires were administered after a median follow-up of 49 months after the end of therapy. The symptoms of fatigue, nausea and vomiting, appetite loss, pain, insomnia, and dyspnea, as well as a negative financial impact, were reported as not frequent and rarely disabling. On the contrary, patients frequently reported gastrointestinal complaints. Diarrhea was present in 6% of patients and was referred as mild; constipation was present in 75% of women and was reported as mild in 30% of cases, moderate in 30%, and severe in 15%. Concerning sexual activity, data indicated a good level of sexual enjoyment with a slight worsening of sexual activity. Incontinence was reported in 28% of cases and appeared to be mild and rarely disabling (all mean values <2). Conclusions: Waiting for ongoing randomized controlled trials, this study confirmed that RH may be considered as a useful treatment plan, according to its negligible long-term impact on quality of life, urinary dysfunction, and sexual function
