A gram-scale synthesis of a series of 1,1,n,n-tetramethyl[n](2,11)teropyrenophanes (n=7-9) has been accomplished as well as the first synthesis of the next higher homologue 1,1,10,10-tetramethyl[10](2,11)teropyrenophane. The scale-up of the original small-scale synthesis required the development of several heavily modified synthetic methods, including a chlorination/Friedel-Crafts alkylation protocol and an iodination/Wurtz coupling protocol, which were performed on 25-30 g and 30-60 g scales, respectively. Two separate sets of conditions for the key teropyrene-forming cyclodehydrogenation reaction at the end of the synthetic pathway were developed, an acid-promoted one for the two less strained congeners and an acid-free method for the two more strained homologues.
The purpose of the present study was to translate and validate the Incontinence Quiz (IQ) questionnaire into a Portuguese version.
The Portuguese version of the 14-item Incontinence Quiz was prepared following translation and back-translation procedures and was tested on a pilot group of 10 women. Internal consistency (Cronbach's α), test-retest reliability (intraclass correlation coefficient [ICC]), and construct validity (using two indicators education level and being a qualified health professional) were assessed in 141 women from the staff of two higher education institutions. Participant's socio-demographic characteristics were collected by questionnaire.
The translation and back-translation process was performed without constraints. Cronbach's α ranged from 0.696 (Item 13) to 0.748 (Item 6), and global Chronbach's α was .740. ICC values for the IQ total score were .78,.57, and.79 for correct, wrong, and do not know answers, respectively. Both economic indicators were positively associated with the percentage of correct answers.
Validity and reliability of the translated Portuguese IQ were achieved which will allow the comparison of results with studies in other cultures.

The American Urological Association/SocietyofUrodynamics,FemalePelvic Medicine and Urogenital Reconstruction stress urinary incontinence (SUI) guidelines strongly recommend the midurethral sling (MUS) for the index female patient with SUI. While numerous studies report long-term outcomes and complications for the retropubic MUS, these are largely absent for the transobturator MUS and are assessed in this study.
This is an Institutional Review Board approvedretrospective chart review of all women who underwent a transobturator MUS at a single institution from 2004 to 2010. Pre- and postoperative assessment included a cough-stress test, SEAPI assessment,and validated quality-of-life (QoL) questionnaires. SUI resolution was defined asno subjective or objective SUI, and no additional surgery to achieve stress continence.
Of 437 women, 305 (70%) had a minimum follow-up of 48 months (mean 88; median 92). SUI was resolved in 69% of the entire cohort and 58% of the 78 women who had MUS only. The median time to SUI recurrence was 38 months in the entire cohort and 18 months in the MUS only group. Perioperative complications were infrequent and typically associated with concomitant surgery. A statistically significant improvement was observed in SEAPI scores and all QoL indices postoperatively.
Long-term resolution of SUI after the transobturator MUS is achieved by 69%, which is commensurate with success rates reported in the literature. Overall, women experience a significant improvement in their QoL after transobturator MUS; however, late recurrences and delayed sequelae may occur. Thus, long-term follow-up is warranted in this population.

One of the challenges in developing effective hair loss therapies is the lack of reliable methods to monitor treatment response or alopecia progression. In this study, we propose the use of optical coherence tomography (OCT) and automated deep learning to non-invasively evaluate hair and follicle counts that may be used to monitor the success of hair growth therapy more accurately and efficiently.
We collected 70 OCT scans from 14 patients with alopecia and trained a convolutional neural network (CNN) to automatically count all follicles present in the scans. selleck The model is based on a dual approach of both detecting hair follicles and estimating the local hair density in order to give accurate counts even for cases where two or more adjacent hairs are in close proximity to each other.
We evaluate our system on 70 OCT manually labeled scans taken at different scalp locations from 14 patients, with 20 of those redundantly labeled by two human expert OCT operators. When comparing the individual human predictwith manual evaluation. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.
Left bundle branch pacing (LBBP) has been suggested as an alternative means to deliver cardiac resynchronization therapy (CRT).
LBBP may deliver resynchronization therapy along with an advantage over traditional biventricular (BiV) pacing in clinical outcomes.
Heart failure patients who presented LBBB morphology according to Strauss's criteria and received successful CRT procedure were enrolled in the present study. Propensity score matching was applied to match patients into LBBP-CRT group and BiV-CRT group. Then, the electrographic data, the echocardiographic data and New York heart association (NYHA) class were compared between the groups.
Twenty-one patients with successful LBBP procedure and another 21 matched patients with successful BiV-CRT procedure were finally enrolled in the study. The QRS duration (QRSd) was narrowed from 167.7 ± 14.9 ms to 111.7 ± 12.3 ms (P < .0001) in the LBBP-CRT group and from 163.6 ± 13.8 ms to 130.1 ± 14.0 ms (P < .0001) in the BiV-CRT group. A trend toward better left ventricular ejection fraction (LVEF) was recorded in the LBBP-CRT group (50.
