ABSTRACT

BACKGROUND: Population-based studies have observed sex biases in the diagnosis and treatment of attention-deficit hyperactivity disorder (ADHD). Females are less likely to be diagnosed or prescribed ADHD medication. This study uses national healthcare records, to investigate sex differences in diagnosis and clinical care in young people with ADHD, particularly regarding recognition and treatment of other mental health conditions. METHODS: The cohort included individuals diagnosed with ADHD, born between 1989 and 2013 and living in Wales between 2000 and 2019. Routine primary and secondary healthcare record data were used to derive diagnoses of ADHD and other neurodevelopmental and mental health conditions, as well as ADHD and antidepressant medications. Demographic variables included ethnicity, socioeconomic deprivation and contact with social services. RESULTS: There were 16,458 individuals diagnosed with ADHD (20.3% females, ages 3-30 years), with a male-to-female ratio of 3.9:1. Higher ratios (4.8:1) were seen in individuals diagnosed younger (<12 years), with the lowest ratio (1.9:1) in those diagnosed as adults (>18). Males were younger at first recorded ADHD diagnosis (mean = 10.9 vs. 12.6 years), more likely to be prescribed ADHD medication and younger at diagnosis of co-occurring neurodevelopmental conditions. In contrast, females were more likely to receive a diagnosis of anxiety, depression or another mental health condition and to be prescribed antidepressant medications, prior to ADHD diagnosis. These sex differences were largely stable across demographic groups. CONCLUSIONS: This study adds to the evidence base that females with ADHD are experiencing later recognition and treatment of ADHD. The results indicate that this may be partly because of diagnostic overshadowing from other mental health conditions, such as anxiety and depression, or initial misdiagnosis. Further research and dissemination of findings to the public are needed to improve awareness, timely diagnosis and treatment of ADHD in females.

ABSTRACT

BACKGROUND: People under the care of mental health services are at increased risk of suicide. Existing studies are small in scale and lack comparisons. AIMS: To identify opportunities for suicide prevention and underpinning data enhancement in people with recent contact with mental health services. METHOD: This population-based study includes people who died by suicide in the year following a mental health services contact in Wales, 2001-2015 (cases), paired with similar patients who did not die by suicide (controls). We linked the National Confidential Inquiry into Suicide and Safety in Mental Health and the Suicide Information Database - Cymru with primary and secondary healthcare records. We present results of conditional logistic regression. RESULTS: We matched 1031 cases with 5155 controls. In the year before their death, 98.3% of cases were in contact with healthcare services, and 28.5% presented with self-harm. Cases had more emergency department contacts (odds ratio 2.4, 95% CI 2.1-2.7) and emergency hospital admissions (odds ratio 1.5, 95% CI 1.4-1.7), but fewer primary care contacts (odds ratio 0.7, 95% CI 0.6-0.9) and out-patient appointments (odds ratio 0.2, 95% CI 0.2-0.3) than controls. Odds ratios were larger in females than males for injury and poisoning (odds ratio: 3.3 (95% CI 2.5-4.5) v. 2.6 (95% CI 2.1-3.1)). CONCLUSIONS: We may be missing existing opportunities to intervene, particularly in emergency departments and hospital admissions with self-harm presentations and with unattributed self-harm, especially in females. Prevention efforts should focus on strengthening routine care contacts, responding to emergency contacts and better self-harm care. There are benefits to enhancing clinical audit systems with routinely collected data.

ABSTRACT

The notion of secure base explains how a child can grow and become independent through access to a significant other (i.e., parent) who is available, encouraging, and noninterfering. The purpose of the current study was to develop an understanding of parental secure base support within the context of youth sport in Sweden, with a specific focus on: (a) what parental behaviors constitute a secure base, and (b) how these behaviors differ across contexts (at home before and after sport, at practice and during competitions). An interpretive descriptive methodology (Thorne, 2016) was used. Interviews were conducted with 13 family triads (children aged 12-15 years) and 1 dyad living in Sweden. Analysis was conducted to illuminate associations, patterns, and relationships within the sample. Analysis led to the development of nine categories of parental behaviors that were perceived to underpin a secure base. Availability was seen to comprise physical presence and support provision, being responsive, and developing positive mental representations. Encouragement encompassed demonstrating that sport participation is valued, motivating to explore sporting endeavors, and reinforcing and rewarding persistence in sports. Interference was described as unrequested interference, requested interference, and intentionally constrained involvement. Additionally, influencing factors such as communication, family structure and culture, were identified. The findings provide an empirical illustration for several behaviors that have been perceived as positive in previous literature, as well as highlighting numerous further complexities, particularly as it relates to interference.

ABSTRACT

Background: There is little information about characteristics and long-term outcomes of individuals who self-harm during a suicide cluster. Aims: To compare characteristics of individuals who self-harmed during a suicide cluster in South Wales (∼10 deaths between December 2007 and March 2008) with others who self-harmed prior to the cluster and to evaluate 10-year self-harm and mortality outcomes. Method: Using records from the hospital serving the catchment area of the suicide cluster, enhanced by national routinely collected linked data, we created the following two groups: individuals who self-harmed (a) during the suicide cluster and (b) 1 year before. We compared individuals' characteristics and performed logistic regression to compute odds ratios of 10-year self-harm and mortality outcomes. Results: Individuals who self-harmed during the cluster were less likely to be hospitalized or have a mental health history than those who self-harmed prior to the cluster. No significant group differences were found for 10-year self-harm outcomes, but all-cause mortality was higher for males. Limitations: Sample size was small, and data were lacking on psychological and social proximity to individuals who died during the suicide cluster. Conclusion: Our findings highlight the importance of long-term healthcare follow-up of those who self-harm during a suicide cluster, particularly males.

ABSTRACT

BACKGROUND: The best management after ileocolonic resection is still unknown in Crohn's disease (CD). We compared step-up and top-down approaches to prevent short and long-term postoperative recurrences in CD patients. METHODS: From a comprehensive database, consecutive CD patients who underwent intestinal resection (2014-2021) were included. Top-down (biologics started within the first month after surgery) or step-up strategies (no biologic between surgery and colonoscopy at 6 months) were performed with systematic colonoscopy at 6 months and therapeutic escalation if Rutgeerts index was ≥i2a (endoscopic postoperative recurrence). Propensity score analysis was applied for each comparison. RESULTS: Among 115 CD patients, top-down was the most effective strategy to prevent endoscopic postoperative recurrence (46.8% vs 65.9%, P = .042) and to achieve complete endoscopic remission (Rutgeerts index = i0; 45.3% vs 19.3%; P = .004) at 6 months. We did not observe any significant difference between the 2 groups regarding clinical postoperative recurrence (hazard ratio [HR], .86 [0.44-1.66], P = .66) and progression of bowel damage (HR, 0.81 [0.63-1.06], P = .12). Endoscopic postoperative recurrence at 6 months was associated with increased risk of clinical postoperative recurrence (HR, 1.97 [1.07-3.64], P 0.029) and progression of bowel damage (HR, 3.33 [1.23-9.02], P = .018). Among the subgroup without endoscopic postoperative recurrence at 6 months, the risks of clinical postoperative recurrence and progression of bowel damage were significantly improved in the top-down group (HR, 0.59 [0.37-0.94], P = .025; and HR, 0.73 [0.63-0.83], P < .001, respectively). CONCLUSIONS: Top-down strategy should be the preferred management to prevent short and long-term postoperative recurrence in CD.


Our data suggest that top-down strategy should be preferred to step-up approach to prevent endoscopic postoperative recurrence, as well as clinical postoperative recurrence and progression of bowel damage in most of the patients with Crohn's disease after bowel resection.

ABSTRACT

The purpose of this study was to examine the association between young players' perception of mother's and father's responsiveness with their self-esteem, anxiety (i.e., worry), and thriving (i.e., positive affect, vitality, and life satisfaction). In total, 314 male British rugby players with a mean age of 16.23 years (SD = 0.26) completed the study in two phases: n = 124 (first dataset), and n = 192 (second dataset). Participants trained on average 3.14 times/week (SD = 0.94) and had been involved in rugby for an average of 8.21 years (SD = 2.89). Participants completed questionnaires measuring perceived parental responsiveness (PPR) for their mother and father, self-esteem, worry about sport performance, and thriving indicators (i.e., positive affect, vitality, and life satisfaction). The results consistently indicated that participants' perceptions of their mother's and father's responsiveness positively related to thriving, and negatively related to their worry about sport performance, mediated by their self-esteem. Overall, the study highlights the need for parents to be provided with insights into the value of being responsive to their child and being encouraged to regularly talk with their child regarding their needs and desires, and seeking to understand how their child perceives the support they currently receive.

ABSTRACT

BACKGROUND: Endoscopic mucosal healing is the current therapeutic target in Crohn's disease. However, transmural healing could lead to better outcomes. AIMS: To assess whether transmural healing or magnetic resonance imaging (MRI) healing are better therapeutic targets than endoscopic mucosal healing to predict long-term improved outcome in Crohn's disease METHODS: From our MRI database, we retrospectively identified all Crohn's disease patients who had MRI and colonoscopy within a 3-month interval (median interval = 17.5 days). Four groups were considered: endoscopic mucosal healing (no ulceration or aphthoid erosion), MRI healing (no MRI signs of inflammation and no complication), transmural healing (combination of endoscopic and MRI healing) or no healing. Outcomes were time to surgery, bowel damage progression, hospitalisation, major outcomes (one of the three previous endpoints) and Crohn's disease-related drug discontinuation. Results were expressed in multivariable analyses adjusted on potential confounders (hazard ratio (HR) [95% confidence interval]). RESULTS: Among 154 patients with Crohn's disease, 51.9% (80/154), 10.4% (16/154), 19.5% (30/154) and 18.2% (28/154) achieved no healing, endoscopic mucosal healing, MRI healing and transmural healing, respectively. Transmural healing (HR = 0.05 [0.00-0.40], P = 0.002) and MRI healing (HR = 0.09 [0.00-0.47], P = 0.005) were associated with lower risk of bowel damage progression than endoscopic mucosal healing. In addition, achieving transmural healing or MRI healing reduced the risk of experiencing major outcomes compared to endoscopic mucosal healing (HR = 0.28 [0.00-0.74], P = 0.01). Patients with transmural healing also had a decreased risk of relapse-related drug discontinuation (HR = 0.35 [0.13-0.95], P = 0.039) compared to those with endoscopic mucosal healing. CONCLUSION: Transmural healing and MRI healing are associated with lower risk of bowel damage progression than endoscopic mucosal healing and could be considered as better therapeutic targets in Crohn's disease.

ABSTRACT

A 58-year-old man presented with fever and chest pain 11 days after atrial fibrillation catheter ablation. The diagnosis of pericardio-oesophageal fistula was made. Aggressive surgical management was decided. The patient was managed using extracorporeal life support, aortic valve replacement and a pulmonary patch, as well as an oesophageal stent. The patient was discharged from hospital approximately 2 months later. The use of a pulmonary patch is a rare but a highly effective technique that can be used in this indication.

ABSTRACT

AIM: To investigate the outcome of flexible endoscopic myotomy performed with the Hook knife in patients with symptomatic Zenker's diverticulum (ZD). METHODS: All consecutive patients treated for ZD at our institution between 7/2012 and 12/2016 were included. The flexible endoscopic soft diverticuloscope-assisted technique with endoclips placement and Hook knife myotomy were performed in all patients. Here we report a retrospective review of prospectively collected data. Demographics, dysphagia score (Dakkak and Bennett), associated symptoms and adverse events were collected pre-procedure, at 2 and 6 mo post-procedure, and at the end of the follow-up period. Clinical success was defined as at least 1-point improvement in dysphagia score and a residual dysphagia score ≤ 1, with no need for reintervention. Dysphagia scores were compared before treatment and at end-of-follow-up using the Wilcoxon test. RESULTS: Twenty-four patients were included. Mean size of ZD was 3.0 cm (range 2-8 cm). Mean number of sessions was 1.17/patient (range 1-3 sessions). Overall clinical success was 91.7%. Two adverse events (8.3%) occurred, and both were managed conservatively. No bleeding or perforation was reported. Mild pain was reported by 9 patients (37.5%). Median hospital stay was 1 d (range 1-6). Median follow-up was 19.5 mo (range 6-53). Mean ± SD dysphagia score was 2.25 ± 0.89 before treatment and decreased to 0.41 ± 0.92 at end-of-follow-up (P < 0.001). Regurgitation and cough dropped from 91.7% and 50% to 12.5% and 0% at the end of follow-up, respectively. Recurrence was observed in 3 patients, and all 3 were symptom-free after one more session. CONCLUSION: The Hook knife, used in the soft diverticuloscope-assisted technique setting, is efficient and safe for treatment of ZD.

ABSTRACT

Background and aims Colonoscopy is currently the reference method to detect colorectal neoplasia, yet some adenomas remain undetected. The water infusion technique and dying with indigo carmine has shown interesting results for reducing this miss rate. The aim of this study was to compare the adenoma detection rate (adenoma and adenocarcinoma; ADR) and the mean number of adenomas per patient (MAP) for blue-water infusion colonoscopy (BWIC) versus standard colonoscopy. Methods We performed a multicenter, randomized controlled trial in eight units, including patients with a validated indication for colonoscopy (symptoms, familial or personal history, fecal occult blood test positive). Consenting patients were randomized 1:1 to BWIC or standard colonoscopy. All colonoscopies were performed by experienced colonoscopists. All colonoscopy quality indicators were prospectively recorded. Results Among the 1065 patients included, colonoscopies were performed completely for 983 patients (514 men; mean age 59.1). The ADR was not significantly different between the groups; 40.4 % in the BWIC group versus 37.5 % in the standard colonoscopy group (odds ratio [OR] 1.13; 95 % confidence interval [CI] 0.87 - 1.48; P = 0.35). MAP was significantly greater in the BWIC group (0.79) than in the standard colonoscopy group (0.64; P = 0.005). For advanced adenomas, the results were 50 (10.2 %) and 36 (7.3 %), respectively (P = 0.10). The cecal intubation rate was not different but the time to cecal intubation was significantly longer in BWIC group (9.9 versus 6.2 minutes; P < 0.001). Conclusion Despite the higher MAP with BWIC, the routine use of BWIC does not translate to a higher ADR. Whether increased detection ultimately results in a lower rate of interval carcinoma is not yet known. CLINICAL TRIALS REGISTRATION: EudraCT 2012-A00548 - 35; NCT01937429.

ABSTRACT

Background and study aim Endoscopic ultrasound (EUS)-guided pelvic abscess drainage has been reported but long-term data remain limited. This two-center study evaluated long-term outcome of EUS-guided pelvic abscess drainage. Patients and methods Between May 2003 and December 2015, 37 consecutive patients were treated for perirectal or perisigmoid abscesses via EUS-guided drainage using plastic or lumen-apposing metal stent (LAMS). Clinical success was defined as complete resolution of the abscess on follow-up computed tomography (CT) scan at 4 weeks with symptom relief. Long-term success was defined as abscess resolution without the need for surgery and without recurrence on long-term follow-up (> 12 months). Results Median abscess size was 60 mm (interquartile range 41 - 70). Causes were postsurgical (n = 31, 83.8 %) or secondary to medical conditions (n = 6, 16.2 %). EUS-guided drainage involved needle aspiration (n = 4), plastic stent placement (n = 29) or LAMS placement (n = 4 patients). Technical and clinical success was achieved in 37 patients (100 %; 95 % confidence interval [CI] 91 - 100) and 34 patients (91.9 %; 95 %CI 78 - 98), respectively (5 patients needed a second EUS-guided intervention within 14 days after drainage). One patient required surgery and one required best supportive care owing to persistent abscess. Early complications were perforation requiring surgery (n = 1), stent migration (n = 1), and rectal discomfort (n = 1). At a median follow-up of 64 months (IQR 19 - 81), two patients experienced abscess recurrence, at 3 and 12 months, respectively, and were treated surgically. Long-term success was achieved in 32 of 37 patients (86.5 %; 95 %CI 71 - 95). Conclusion EUS-guided drainage of pelvic abscess is safe, has good long-term outcome, and should be considered as an alternative to percutaneous and surgical drainage.

ABSTRACT

BACKGROUND: Duodenal stenosis is one of the most common causes of failed ERCP for obstructive jaundice. Alternative approaches include anterograde biliary drainage, with higher morbidity. We report in this study the efficacy and safety of temporary placement of a covered duodenal self-expandable metal stent (cSEMS) in order to access the papilla and achieve secondary retrograde biliary drainage in patients with obstructive jaundice and failed ERCP due to concomitant duodenal stenosis. METHODS: From June 2006 to March 2014, a total of 26 consecutive patients presenting obstructive jaundice without severe sepsis with failed ERCP due to duodenal invasion were enrolled. A temporary 7-day duodenal cSEMS was placed during the failed ERCP, and a second ERCP was attempted at day 7 after duodenal stent removal. RESULTS: Duodenal cSEMS placement and retrieval were technically successful in all cases. Access to the papilla at day 7 was possible in 25 cases (96 %, 95 % CI 80-99 %). Secondary successful ERCP was achieved in 19 cases (76 %, 95 % CI 55-91 %, i.e., 73 %, 95 % CI 73-86 %, in an intention-to-treat analysis). Mean bilirubin level was 102 ± 90 µmol/L at baseline rising to 164 ± 121 µmol/L at day 7. There were 6 stent migrations and no adverse events recorded between the two ERCPs. CONCLUSIONS: When ERCP for obstructive jaundice fails due to duodenal invasion, temporary cSEMS placement offers a safe and effective way to achieve successful secondary ERCP while avoiding riskier endoscopic ultrasound or percutaneous transhepatic anterograde biliary drainage.

ABSTRACT

INTRODUCTION: Benign esophageal strictures arise from various etiologies and are frequently encountered. Although endoscopic dilation is still the first-line therapy, recurrent strictures do occur in approximately 10% of the cases and remains a challenge to gastroenterologists. Areas covered: A literature search was performed using PubMed and Google Scholar databases for original and review articles on endoscopic treatment of benign esophageal strictures. This review outlines the main available treatment options and its controversies in the management of refractory benign esophageal strictures. Expert commentary: Adding local steroid injections to dilation can be effective for peptic stenosis and strictures after endoscopic submucosal dissection, but remains uncertain for anastomotic strictures. Intralesional injections of mitomycin-C could be useful in corrosive strictures. Incisional therapy can be a reliable alternative in Schatzki rings and in anastomotic strictures, in experienced hands. By contrast, long-term outcome with endoprosthetic treatment is disappointing, and stent placement should be carefully considered and individualized.

ABSTRACT

We have developed a technique to study how good computers can be at diagnosing gastrointestinal lesions from regular (white light and narrow banded) colonoscopic videos compared to two levels of clinical knowledge (expert and beginner). Our technique includes a novel tissue classification approach which may save clinician's time by avoiding chromoendoscopy, a time-consuming staining procedure using indigo carmine. Our technique also discriminates the severity of individual lesions in patients with many polyps, so that the gastroenterologist can directly focus on those requiring polypectomy. Technically, we have designed and developed a framework combining machine learning and computer vision algorithms, which performs a virtual biopsy of hyperplastic lesions, serrated adenomas and adenomas. Serrated adenomas are very difficult to classify due to their mixed/hybrid nature and recent studies indicate that they can lead to colorectal cancer through the alternate serrated pathway. Our approach is the first step to avoid systematic biopsy for suspected hyperplastic tissues. We also propose a database of colonoscopic videos showing gastrointestinal lesions with ground truth collected from both expert image inspection and histology. We not only compare our system with the expert predictions, but we also study if the use of 3D shape features improves classification accuracy, and compare our technique's performance with three competitor methods.

ABSTRACT

BACKGROUND AND GOALS: Using a self-expandable metallic stent (SEMS) in the cervical esophagus is controversial due to an increased risk of complications. Here we assessed a new type of SEMS purpose-designed for the cervical esophagus area. STUDY: Patients with malignant or benign stenosis within 4 cm distance of the upper esophageal sphincter who underwent placement of a SEMS with a shorter proximal head (Niti-S Esophageal Covered Stent-Cervical-type, NSECSC), were included. Main outcome measures were the functional outcome, tolerance, complications, recurrent dysphagia, and survival. RESULTS: About 37 patients had an NSECSC placed between April 2008 and June 2013 for esophageal stenosis (malignant=20, benign=17), 5 with associated tracheoesophageal fistula. The mean stenosis-upper esophageal sphincter distance was 1.86±1.27 cm. The median follow-up was 150 days. Dysphagia improved in 27/37 cases (73%). Short-term and long-term tolerance without needing stent removal was 92% and 82%, respectively. The complication rate was 59% (22/37): 32% (n=14) major complications [fistula (3), perforation (3), aspiration pneumonia (5), laryngeal dyspnea (2), and bleeding (1)], and 27% (n=10) minor complications [pain (7) or dysphonia (3)]. A multivariate analysis confirmed a higher risk of major complications in cases of benign stenosis (odds ratio=5.2; 95% confidence interval, 1.05-25.90; P=0.04). Recurrent dysphagia occurred in 15 patients (obstruction=7, migration=8). CONCLUSIONS: The NSECSC does not appear less morbid than standard SEMS in the cervical esophageal area, but could be useful in malignant indications as it is well-tolerated and offers effective palliation of the dysphagia. However, this device should not be used in benign cervical esophageal strictures or fistulas.

ABSTRACT

BACKGROUND AND STUDY AIM: Endoscopic ultrasound (EUS)-guided biliary access is an alternative to percutaneous access after failed endoscopic retrograde cholangiopancreatography (ERCP). This report presents 7 years' cumulative experience of EUS-guided biliary drainage for obstructive jaundice in patients with failed ERCP. PATIENTS AND METHODS: Between February 2006 and February 2013, 101 patients (malignant = 98, benign = 3) with previous failed ERCP underwent an EUS intra- or extrahepatic approach with transluminal stenting or an EUS-guided rendezvous procedure with transpapillary stent placement. A single endoscopist performed all procedures. RESULTS: A total of 71 patients underwent the intrahepatic approach (66 hepatogastrostomies and 5 EUS-guided rendezvous), and 30 underwent the extrahepatic approach (26 choledochoduodenostomies, 1 choledochojejunostomy, 1 choledochoantrostomy, and 2 EUS-guided cholangiographies). Technical and clinical success rates were 98.0 % and 92.1 %, respectively. There was no difference in efficacy between hepatogastrostomies and choledochoduodenostomies (94 % vs. 90 %; P = 0.69) or in major complications (10.6 % vs. 6.7 %; P = 1). Adverse events occurred in 12 patients (11.9 %): 10 in the hepatogastrostomy group (2 limited pneumoperitoneum, 1 hepatic hematoma, 5 bile leakage, 2 sepsis), and 2 in the choledochoduodenostomy group (1 arteriobiliary fistula and 1 sepsis). There were six procedure-related deaths, five among the first 50 patients and one among the last 51 patients. Hepatogastrostomy vs. choledochoduodenostomy, plastic vs. metal stenting, stent-in-stent vs. 1 stent, nasobiliary drain, or postoperative octreotide infusion were not prognostic of bile leakage. CONCLUSION: EUS-guided biliary drainage is an efficient technique, but is associated with significant morbidity that seems to decrease with the learning curve. It should be performed in tertiary care centers in selected patients. Prospective randomized studies are needed to compare EUS-guided biliary drainage with percutaneous transhepatic cholangiography drainage.
