The Protective Role of Self-Compassion on Risk Factors for Non-suicidal Self-Injury in Adolescence

Non-suicidal self-injury (NSSI) in adolescence is a serious public health problem. Although self-compassion is a protective factor of mental health difficulties in adult populations, its potential impact on adolescence remains scarcely explored. Therefore, we aimed to test whether self-compassion can mitigate the impact of daily peer hassles and depressive symptoms on NSSI. The participants were 643 adolescents (51.6 % female) with ages between 12 and 18 years, from middle and secondary schools. Self-report questionnaires were used to measure daily peer hassles, depressive symptoms, self-compassion and NSSI. Daily peer hassles were positively correlated with depressive symptoms and NSSI. Self-compassion was inversely associated with daily peer hassles and depressive symptoms and NSSI. Path analysis showed that self-compassion had a moderator effect on the association between depressive symptoms and NSSI. Results suggest that self-compassion can be a protective process, as it may buffer against the impact of depressive symptoms on NSSI. This study presents preventive and clinical implications for educators and therapists working with adolescents.     

Short- and long-term results of liver transplantation in infants aged less than 6 months

BACKGROUND: Despite major surgical and medical advances, it is still a challenge to perform transplantation in small infants. This study, focusing on short- and long-term outcomes, summarizes our 10-year experience with liver transplantation (LTx) in infants aged less than 6 months. PATIENTS AND METHODS: We analyzed 43 patients aged 6 months or less (range: 12-184 days, median: 136 days) whose median weight at the time of LTx was 5.8 kg (range: 2.8-8.0 kg). The reasons for LTx were biliary atresia (n=27; 62.8%), neonatal hepatitis (n=6; 14%), neonatal cholestasis (n=4; 9.3%), and miscellaneous (n=6; 14%). The patients were followed up for a median time of 3 years and evaluated with respect to graft function, physical, and neurodevelopmental outcome. RESULTS: The patient survival was 90.7% after 1 year and 87.2% after 2 years. The graft survival was 86% after 1 year and 82.1% after 2 years. Twelve patients (27.9%) experienced 15 surgical complications requiring intervention, two of whom demonstrated vascular thrombosis (4.7%). Acute early rejection occurred in 15 patients (34.9%), and chronic rejection occurred in 3 patients (7%); 83.3% of the patients had normal liver function test results at the time of evaluation. Complications such as posttransplant lymphoproliferative disease (4.7%) and persistent arterial hypertension (4.7%) were rarely seen. The physical and neurodevelopmental outcomes were good. CONCLUSIONS: LTx in infants aged less than 6 months provides excellent short- and long-term results. Low weight or young age of infants awaiting LTx should not be exclusion criteria for LTx.     

Permanent access to the portal system for cellular transplantation using an implantable port device.

A novel application of the implantable Port-a-Cath (PAC) system is described in the context of cellular transplantation. A silicone catheter was inserted in a collateral branch of the portal vein and connected to a port device positioned subcutaneously on the left thoracic cage. This permanent vascular access allowed iterative intraportal infusions of allogenic hepatocytes without the need of repeated transhepatic catheterization of the portal vein. Using this technique, repeated infusions of cryopreserved and / or fresh hepatocytes were successfully carried out in 3 children with inborn errors of liver metabolism, with the aim of progressively providing a sufficient mass of transplanted liver cells to stabilize the metabolic condition of the patients. We suggest that this technique might also be valuable in pancreatic islet cell transplantation.     

Morbidity of Focal Therapy in the Treatment of Localized Prostate Cancer

Background

Focal therapy (FT) for prostate cancer (PCa) seems to be part of a natural evolution in the quest to improve the management of early organ-confined disease.

Objective

To assess the morbidity of the initial experience of FT in a tertiary referral center for PCa management.

Design, setting, and participants

From 2009 to 2011, a total of 1213 patients with clinically localized PCa were treated at our institution. Of these patients, 547 were considered to have indolent disease according to the D’Amico criteria for low-risk disease plus unilateral disease with a maximum of three positive biopsies. A total of 106 patients underwent FT using high-intensity focused ultrasonography (HIFU), brachytherapy, cryotherapy, or vascular-targeted photodynamic therapy (VTP).

Outcome measurements and statistical analysis

Complications were prospectively recorded and graded according to the Clavien-Dindo scale. Data were prospectively collected and retrospectively analyzed.

Results and limitations

This study included 106 patients, median age 66.5 yr (interquartile range [IQR]): 61–73), who had a prostate hemiablation; 50 patients (47%) had cryotherapy, 23 patients (22%) had VTP, 21 patients (20%) received HIFU, and 12 patients (11%) had brachytherapy. The median prostate-specific antigen (PSA) level was 6.1 ng/ml (IQR: 5–8.1), all the patients had a biopsy Gleason score of 6, and the median prostate weight was 43 g (IQR: 33–55). The median International Prostate Symptom Score was 6 (IQR: 3–10), and the median International Index of Erectile Function score was 20 (IQR: 15–23). After treatment, the median PSA at 3, 6, and 12 mo was 3.1 2.9, and 2.7 ng/ml (IQR: 2–5.1, 1.1–4.7, and 1–4.4), respectively. Thirteen percent of the patients experienced treatment-related complications. There were 11 minor medical complications (10 grade 1 complications and 1 grade 2 complication), 2 grade 3 complications, and no grade 4 or higher complications.

Conclusions

FT for a highly selected population with PCa is feasible and had an acceptable morbidity with <2% major complications.     

Spatial learning and neurogenesis: Effects of cessation of wheel running and survival of novel neurons by engagement in cognitive tasks

Physical exercise stimulates cell proliferation in the adult dentate gyrus and facilitates acquisition and/or retention of hippocampal‐dependent tasks. It is established that regular physical exercise improves cognitive performance. However, it is unclear for how long these benefits last after its interruption. Independent groups of rats received both free access to either unlocked (EXE Treatment) or locked (No‐EXE Treatment) running wheels for 7 days, and daily injections of bromodeoxyuridine (BrdU) in the last 3 days. After a time delay period of either 1, 3, or 6 weeks without training, the animals were tested in the Morris water maze (MWM) either in a working memory task dependent on hippocampal function (MWM‐HD) or in a visible platform searching task, independent on hippocampal function (MWM‐NH). Data confirmed that exposure of rats to 7 days of spontaneous wheel running increases cell proliferation and neurogenesis. In contrast, neurogenesis was not accompanied by significant improvements of performance in the working memory version of the MWM. Longer time delays between the end of exercise and the beginning of cognitive training in the MWM resulted in lower cell survival; that is, the number of novel surviving mature neurons was decreased when this delay was 6 weeks as compared with when it was 1 week. In addition, data showed that while exposure to the MWM‐HD working memory task substantially increased survival of novel neurons, exposure to the MWM‐NH task did not, thus indicating that survival of novel dentate gyrus neurons depends on the engagement of this brain region in performance of cognitive tasks. © 2015 Wiley Periodicals, Inc.     

Network centrality in the human functional connectome

The network architecture of functional connectivity within the human brain connectome is poorly understood at the voxel level. Here, using resting state functional magnetic resonance imaging data from 1003 healthy adults, we investigate a broad array of network centrality measures to provide novel insights into connectivity within the whole-brain functional network (i.e., the functional connectome). We first assemble and visualize the voxel-wise (4 mm) functional connectome as a functional network. We then demonstrate that each centrality measure captures different aspects of connectivity, highlighting the importance of considering both global and local connectivity properties of the functional connectome. Beyond "detecting functional hubs," we treat centrality as measures of functional connectivity within the brain connectome and demonstrate their reliability and phenotypic correlates (i.e., age and sex). Specifically, our analyses reveal age-related decreases in degree centrality, but not eigenvector centrality, within precuneus and posterior cingulate regions. This implies that while local or (direct) connectivity decreases with age, connections with hub-like regions within the brain remain stable with age at a global level. In sum, these findings demonstrate the nonredundancy of various centrality measures and raise questions regarding their underlying physiological mechanisms that may be relevant to the study of neurodegenerative and psychiatric disorders.     

Anterior suspension combined with posterior reconstruction during robot-assisted laparoscopic prostatectomy improves early return of urinary continence: a prospective randomized multicentre trial

Study Type – Therapy (RCT) Level of Evidence 1b What's known on the subject? and What does the study add? Urinary incontinence is one of the major drawbacks of radical prostatectomy, regardless of the procedure used (i.e. open, laparoscopic or robotic‐assisted). Several technical modifications have been described to improve postoperative continence, highlighting the role of puboprostatic ligaments and posterior reconstruction of the rhabdomyosphincter. The results obtained are inconsistent when applied to robotic surgery. The present multicentre randomized study shows that anterior suspension combined with posterior reconstruction is a safe and easy‐to‐perform technique for improving early continence after robotic‐assisted laparoscopic prostatectomy.

OBJECTIVE

• ? To assess the impact on urinary continence of anterior retropubic suspension with posterior reconstruction during robot‐assisted laparoscopic prostatectomy (RALP).

PATIENTS AND METHODS

• ? In total, 72 patients who were due to undergo prostatectomy between July 2009 and July 2010 were prospectively randomized into two groups: group A underwent a standard RALP procedure and group B had anterior suspension and posterior reconstruction during RALP.
• ? The primary outcome measure was urinary continence, assessed using the University of California Los Angeles Prostate Cancer Index questionnaire at 15 days, and at 1, 3 and 6 months, after surgery. Other data recorded were operation duration, blood loss, length of hospital stay, duration of bladder catheterization, complications and positive margin rate.

RESULTS

• ? The continence rates at 15 days, and at 1, 3 and 6 months, after surgery were 3.6%, 7.1%, 15.4% and 57.9%, respectively, in group A, and 5.9%, 26.5%, 45.2% and 65.4%, respectively, in group B. The continence rates differed statistically between groups at 1 and 3 months (P = 0.047 and P = 0.016, respectively).
• ? There was no significant difference between groups regarding complications (P = 0.8) or positive margin rate (P = 0.46).

CONCLUSION

• ? Anterior suspension associated with posterior reconstruction during RALP improved the early return of continence, without increasing complications.

     

The role of clips in preventing migration of fully covered metallic esophageal stents: a pilot comparative study

Background

Migration is the most common complication of the fully covered metallic self-expanding esophageal stent (SEMS). This study aimed to determine the potential preventive effect of proximal fixation on the mucosa by clips for patients treated with fully covered SEMS.

Methods

In this study, 44 patients (25 males, 57%) were treated with fully covered SEMS including 22 patients with esophageal stricture (4 malignant obstructions, 6 anastomotic strictures, and 12 peptic strictures) and 22 patients with fistulas or perforations (10 anastomotic leaks, 4 perforations, and 8 postbariatric surgery fistulas). The Hanarostent (n?=?25), Bonastent (n?=?5), Niti-S (n?=?12), and HV-stent (n?=?2) with diameters of 18 to 22?mm and lengths of 80 to 170?mm were used. Two to four clips (mean, 2.35?±?0.75 clips) were used consecutively in 23 patients to fix the upper flared end of the stent with the esophageal mucosal layer. Stent migration and its consequences were collected in the follow-up assessment with statistical analysis to compare the patients with and without clip placement.

Results

No complication with clip placement was observed, and the retrieval of the stent was not unsettled by the persistence of at least one clip (12 cases). Stent migration was noted in 15 patients (34%) but in only in 3 of the 23 patients with clips (13%). The number of patients treated to prevent one stent migration was 2.23. The predictive positive value of nonmigration after placement of the clip was 87%. In the multivariate analysis, the fixation with clips was the unique independent factor for the prevention of stent migration (odds ratio, 2.3; 95% confidence interval, 0.10?C0.01; p?=?0.03).

Conclusions

Anchoring of the upper flare of the fully covered SEMS with the endoscopic clip is feasible and significantly reduces stent migration.     

Prevalence of vitamin D insufficiency in Swiss teenagers with appendicular fractures: a prospective study of 100 cases

Background

The significance of subclinical vitamin D deficiency in the pathogenesis of fractures in children and adolescents currently remains unclear.

Objective

We aimed to determine the prevalence of vitamin D insufficiency and its effect on bone mineral density (BMD) and bone mineral content (BMC) values in a collective of Swiss Caucasian children with a first episode of appendicular fracture.

Design and methods

One hundred teenagers with a first episode of appendicular fracture [50 upper limb fractures (group 1) and 50 lower limb fractures (group 2)] and 50 healthy controls (group 3) were recruited into a cross-sectional study. The BMC and BMD values were measured by dual-energy X-ray absorptiometry, and serum 25 hydroxyvitamin D [25(OH)D] was assessed by electrochemiluminescence immunoassays.

Results

From the 100 injured teenagers in the study, 12 % had deficient vitamin D levels (<20 ng/mL; <50 nmol/L) and 36 % had insufficient levels (≥20 <30 ng/mL; ≥50 <78 nmol/L), whereas 6 and 34 % of healthy controls were, respectively, vitamin D deficient and insufficient. There were no significant differences for serum 25(OH)D levels, L2–L4 BMD Z-score, and L2–L4 BMC Z-score variables (p = 0.216) between the three groups nor for the calcaneal BMD Z-score variables (p = 0.278) between healthy controls and lower limb fracture victims. Investigations on the influences of serum 25(OH)D on BMD and BMC showed no correlation between serum 25(OH)D and L2–L4 BMD Z-scores (r = −0.15; p = 0.135), whereas low but significant inverse correlations were, surprisingly, detected between serum 25(OH)D and calcaneal BMD Z-scores (r = −0.21; p = 0.034) and between serum 25(OH)D and L2–L4 BMC Z-scores (r = −0.22; p = 0.029).

Conclusions

A significant proportion of Swiss Caucasian teenagers were vitamin D insufficient, independent of limb fracture status, in our study. However, this study failed to show an influence of low vitamin D status on BMD and/or BMC of the lumbar spine and heel.     

Laparoscopic sacral colpopexy approach for genito-urinary prolapse: experience with 363 cases

OBJECTIVE: To evaluate the surgical outcome, complications and benefits of laparoscopic double promonto-fixation for patients with pelvic prolapse. METHODS: Women with genito-urinary prolapse underwent a transperitoneal placement of a 100% polyester mesh on the anterior vaginal wall and a posterior mesh on the levator ani muscle. Both of these were anchored to the sacral promontory. A TVT was placed simultaneously in patients who had concurrent stress urinary incontinence. RESULTS: A total of 363 patients were operated upon between 1996 and 2002. Their mean age was 63 (range 35-78), average follow-up was 14.6 months, the mean operating time was 97 minutes. There were 8 conversions due to anesthetic or surgical difficulties. Follow up was done by a postal questionnaire and physical examination at 6 months and then yearly. 96% were satisfied with the results of their operation and no patients complained of sexual dysfunction. There was a 4% recurrence rate of prolapse, 3 vaginal erosions, 2 urinary retentions that required TVT section, 1 bowel incarcerations, 1 spondylitis and 2 mesh infection. CONCLUSIONS: Laparoscopic promonto-fixation is feasible and highly effective technique that offers good long-term results with complication rates similar to open surgery, with the added benefits of minimally invasive surgery.
