Notes

Two scientific studies to be able to GWAS: generally there and back again.
Word discrimination effects were limited and consisted of only small increases in vowel duration. Interaction effects between noise and similarity indicated that the phonological similarity of sequences containing both sibilants and/or both vowels influenced articulation in ways not related to speech clarity. Conclusion The findings of this study indicate that sensorimotor control of speech exhibits some sensitivity to noise spectral characteristics. However, productions of sibilants and vowels were not sensitive to their importance in discriminating the words in a sequence. In addition, phonological similarity effects were observed that likely reflected processing demands related to the recall and sequencing of high-similarity words.Purpose Concentrations of sex steroid hormones-estrogens, progesterone, and testosterone-have been associated with premenstrual and menstrual vocal symptoms. Erlotinib datasheet However, the extent to which these symptoms may be reflected on acoustical features of the voice is still debated. This study investigates variations in fundamental frequency (f o) and related parameters in connected speech across phases of the menstrual cycle and during the use of a combined oral contraceptive pill (OCP). Method Electrolaryngographic recordings were made, and blood samples were collected at three different phases of the menstrual cycle-menstrual, follicular, and luteal-for placebo and OCP use. These two conditions were blindly and randomly allocated in the study. Speaking f o (SFF), SFF standard deviation, SFF rate of change, SFF slope, maximum and minimum f o, and f o range were extracted for nine healthy females while reading a phrase from the Rainbow Passage. Concentrations of sex hormones were analyzed in serum. Nonparametric statistical tests were carried out to assess differences between phases and conditions. Results SFF, its standard deviation, and maximum f o were significantly different between phases of the menstrual cycle for placebo use only. Menstrual phase showed the lowest values. Maximum and minimum f o were significantly different between placebo and OCP use for menstrual and follicular phases, respectively. Conclusions Fluctuations in sex steroid hormones across the menstrual cycle alter f o in speech more than a particular hormonal concentration. OCP use seems to have a stabilizing effect on the voice relative to f o and related parameters in speech.Objective Although the etiopathogenesis of acne rosacea has not yet been clearly elucidated, it has been discussed over the years that autoimmunity may play a role. Genetic and environmental factors are known to have combined effects in the background of autoimmunity, but it has recently been emphasized that an impaired intestinal barrier system is also involved in the development of the disease. Zonulin is a protein that reversibly increases intestinal permeability. This study aimed to evaluate the zonulin levels in acne rosacea.Methods A total of 61 individuals, 30 diagnosed with acne rosacea and 31 healthy controls, were included in this study. There was no difference between the two groups in terms of age, gender, and body mass index. Zonulin was studied using the enzyme-linked immunosorbent assay.Results The serum zonulin levels were found to be significantly higher in the patient group than in the control group (18.5 ± 2.9 ng/ml and 13.2 ± 2.7 ng/ml, respectively; p  less then  .001).Conclusion This is the first study in the literature to demonstrate that the serum zonulin levels are increased in patients with acne rosacea.PURPOSE National epidemiologic data on melanoma are scarce in Brazil. The current work presents final demographic, clinical, and pathologic results from the Brazilian Melanoma Group database to detail how patients with melanoma present at diagnosis. METHODS The online database includes patients diagnosed between 1982 and 2015 and evaluated at their centers of origin between 2001 and 2016. The primary objective was to describe the demographic, clinical, and pathologic characteristics of the patients, and secondary objectives were to investigate the association between clinical and pathologic variables of interest. RESULTS A total of 1,596 patients were included. Median age was 52 years, 57% were women, and the majority were identified as white. Invasive melanoma was diagnosed in 1,297 patients, mostly localized, whereas 299 (19%) had in situ disease (TisN0M0). Only 165 patients had initial lymph node involvement. Fitzpatrick skin types I or II were slightly more frequent with in situ melanoma (73%) than with invasive disease (67%; P = .054). The median Breslow thickness was 0.95 mm, Clark levels 2 and 3 comprised nearly 70% of cases, and ulceration was present in 18% of patients. The mitotic rate was significantly associated with the presence of ulceration and both vascular and perineural invasion but not with margin positivity, whereas histologic regression was associated with both intratumoral and peritumoral inflammatory infiltrates. CONCLUSION Despite the limitations of an observational, registry-based study, the current results provide a general profile of patients with cutaneous melanoma in Brazil at the time of diagnosis.Introduction Allogeneic transplantation represents a potentially curative procedure for various lethal conditions; however, it is associated with serious immune mediated complications. The most serious complication is graft-versus-host disease (GVHD). Acute GVHD (aGVHD) is unresponsive to initial corticosteroid therapy in ~40% of cases. Corticosteroid-refractory aGVHD (CR-aGVHD) represents a significant unmet need with nearly 60% mortality in patients developing this state.Areas covered We review landmark trials which led to the US FDA approval of Ruxolitinb for the treatment of CR-aGVHD. Ruxolitinib phosphate is a Janus Kinase 1 and 2 inhibitor which inhibits pro-inflammatory signaling, and modulates T-cell subsets to an anti-inflammatory phenotype. Ruxolitinib was recently prospectively studied for the treatment of CR-aGVHD in the REACH1 trial, which added Ruxolitinib to corticosteroid therapy. This trial demonstrated favorable results with 73% of patients ultimately responding. Among responders, over 70% remained alive at 6 months.
