AbstractBackround and aimsHaving entered the recent public and research zeitgeist, microdosing involves consuming sub-perceptual doses of psychedelic drugs, allegedly to enhance performance, creativity, and wellbeing. The results of research to date have been mixed. Whereas most studies have reported positive impacts of microdosing, some microdosers have also reported adverse effects. In addition, research to date has revealed inconsistent patterns of change in personality traits. This prospective study explored the relationship between microdosing, personality change, and emotional awareness.MethodsMeasures of personality and alexithymia were collected at two time points. 76 microdosers participated at baseline. Invitations to a follow-up survey were sent out after 31 days, and 24 participants were retained.ResultsConscientiousness increased, while neuroticism decreased across these time points (n = 24). At baseline (N = 76), neuroticism was associated with alexithymia. In addition, neuroticism correlated negatively with duration of prior microdosing experience, and extraversion correlated positively with both duration of prior microdosing experience and lifetime number of microdoses.ConclusionThese results suggest that microdosing might have an impact on otherwise stable personality traits.

SynopsisA prospective study was carried out to investigate the relationship between family attitudes and relapse in a cohort of 80 schizophrenic patients followed up for 2 years. A significant relationship was found between attitudes as measured by means of a semantic differential during hospitalization and later relapse. Lack of treatment compliance, negative symptoms, unemployment and poor pre-morbid adjustment were also associated with relapse. In a multivariate analysis some of these variables changed their predictive power but the association between attitudes and relapse was maintained.

Up to date, human urotensin II (UII) is the most potent vasoconstrictor in mammalian animals. To explore whether UII played an important role in the development of hypertension, we conducted a prospective study in Changshu city, China. The baseline investigation was carried out in 2007, and the first follow-up investigation was conducted in 2013. From the participants, we randomly obtained 2000 normotensive subjects aged 40 years and older without any severe disease at baseline and examined plasma UII and endothelin-1 (ET-1) with their blood samples at baseline. Logistic models were used to analyze the association between baseline UII, baseline ET-1, and newly occurring hypertension. In 1,819 subjects with complete data, 723 subjects developed into hypertensive in about five years. After adjusting some potential confounders, the odds ratio (95% confidence interval) for risk of hypertension comparing the highest with the lowest quartile of baseline UII was 0.888 (0.689–1.144). The role of UII in the development of hypertension was not found in the current study; therefore, further research studies should be conducted to explore the relationship between UII and hypertension.

Abstract Objective The aim of this article was to analyze the clinical and radiological outcomes of transpedicular decompression (posterior approach) and anterolateral approach in patients with traumatic thoracolumbar spinal injuries. Methods  It was a prospective study of patients with fractures of dorsolumbar spine from December 2011 to December 2013. A total of 60 patients with traumatic spinal injuries were admitted during the study period (December 2011–2013), of which 51 cases were finally selected and taken for operations while 3 were eventually lost in follow-up. Twenty patients were operated by anterolateral approach, titanium mesh cage, and fixation with bicortical screws. Twenty-eight patients were treated with posterior approach and transpedicular screw fixation. Clinical and radiographic evaluations were performed on all 48 patients before and after surgery. Results There were 48 patients of thoracolumbar burst fractures with 40 male and 8 female patients. Range of follow-up was from 1 month to 20 months, with a mean of 7.4. Preoperatively in anterior group, 65% of the patients were bed ridden, 20% patients were able to walk with support, and 15% of the patients were able to walk without support. In posterior group, 78.57% patients were bed ridden, 10.71% were able to walk with support, and 10.71% patients were able to walk without support. Kyphotic angle changes were seen in 16 patients out of 18 in anterior group and 20 patients in posterior group out of 25. Out of 18 patients in anterior group, 14 showed reduction in kyphotic angle of 10 to 100 (improvement), with mean improvement of 4.070. In posterior group, 7 patients showed improvement of 10 to 80 (reduction in kyphotic angle) whereas 13 patients showed deterioration of 1 to 120. The mean improvement was 2.140 in 7 patients and mean deterioration was 4.920. No statistical difference was found (p > 0.05) regarding improvement in urinary incontinence during the follow-up period. Conclusion There are significant differences in anterior and posterior approaches in terms of clinical improvement. Compared with posterior approach, the anterolateral approach can reduce fusion segment and well maintain the kyphosis correction. The selection of treatment should be based on clinical and radiological findings, including neurological deficit.

AbstractThe detection of circulating cell-free DNA (cfDNA) by liquid biopsy is reported to provide prognostic information in colorectal cancer (CRC). Although the frequency of BRAF V600E mutation in CRC is less than 10%, it is associated with poor responses to conventional chemotherapy. We conducted a prospective study to investigate the relationship between the perioperative mutant allele frequency (MAF) of BRAF V600E and tumor recurrence, and to evaluate the possibility of early detection of recurrence. Among 362 patients who underwent radical resection, cfDNA was extracted from the perioperative blood of 11 CRC patients with BRAF V600E mutation and analyzed using the digital polymerase chain reaction (dPCR) system. The median follow-up time was 22 months, and there were four cases of recurrence. Although there was no correlation between recurrence and the perioperative MAF of BRAF V600E, tumor diameter was correlated with the MAF (p = 0.024), and the MAF increased with time in two patients from whom additional samples were obtained prior to recurrence. In this study, we identified a correlation between the pathological tumor diameter and the MAF, but it was difficult to predict recurrence by measuring cfDNA with BRAF V600E mutation in the perioperative period of radical resection of CRC.

AbstractGold eyelid implantation is widely considered the procedure of choice to reanimate the upper eyelid in paralytic lagophthalmos. Commercially supplied implants are not readily available in all places and are sometimes cumbersome to import.Objective:We aimed to devise a method whereby every surgeon performing gold eyelid implantation could have easy and quick access to the implant. Furthermore, we aimed to develop a means of creating an implant of the exact weight required for complete eyelid closure.Study design and setting:A prospective study was performed from 1997 to 2005 in a tertiary research hospital, involving 50 subjects requiring gold upper eyelid implantation and using the technique in question.Results:Only patients with a minimum follow up of one year were included in the study group. Symptoms improved in 96 per cent of subjects, who were able to dispense with eyedrops and eye ointments. Visual acuity improved in 92 per cent of patients. There were two extrusions amongst the early cases.Conclusion and significance:Customised gold eyelid implantation offers an alternative in regions where commercial implants are not easily obtained.
