- Blood-brain barrier (BBB) injury is prevalent in patients with HIV-associated dementia (HAD) and is a frequent feature of HIV encephalitis. Signs of BBB damage are also sometimes found in neuroasymptomatic HIV-infected individuals without antiretroviral therapy (ART). The aim of this study was to investigate the integrity of the BBB before and after initiation of ART in both neuroasymptomatic HIV infection and in patients with HAD.We determined BBB integrity by measuring cerebrospinal fluid (CSF)/plasma albumin ratios in archived CSF samples prior to and after initiation of ART in longitudinally-followed neuroasymptomatic HIV-1-infected individuals and patients with HAD. We also analyzed HIV RNA in blood and CSF, IgG Index, CSF WBC counts, and CSF concentrations of β2-micoglobulin, neopterin, and neurofilament light chain protein (NfL).We included 159 HIV-infected participants; 82 neuroasymptomatic individuals and 77 with HAD. All neuroasymptomatic individuals (82/82), and 10/77 individuals with HAD, were longitudinally followed with a median (interquartile range, IQR) follow-up of 758 (230-1752) days for the neuroasymptomatic individuals, and a median (IQR) follow-up of 241 (50-994) days for the individuals with HAD. Twelve percent (10/82) of the neuroasymptomatic individuals and 80% (8/10) of the longitudinally-followed individuals with HAD had elevated albumin ratios at baseline. At the last follow-up, 9% (7/82) of the neuroasymptomatic individuals and 20% (2/10) of the individuals with HAD had elevated albumin ratios. ART significantly decreased albumin ratios in both neuroasymptomatic individuals and in patients with HAD.These findings indicate that ART improves and possibly normalizes BBB integrity in both neuroasymptomatic HIV-infected individuals and in patients with HAD.

- Several risk factors are associated with gallstone disease after bariatric surgery, but the underlying pathophysiological mechanisms of gallstone formation are unclear. We hypothesize that gallstone formation after bariatric surgery is induced by different pathways compared with gallstone formation in the general population, since postoperative formation occurs rapidly in patients who did not develop gallstones in preceding years. To identify both pathophysiological and potentially protective mechanisms against postoperative gallstone formation, we compared the preoperative fasting metabolome, fecal microbiome, and liver and adipose tissue transcriptome obtained before or during bariatric surgery of obese patients with and without postoperative gallstones. In total, 88 patients were selected from the BARIA longitudinal cohort study. Within this group, 32 patients had postoperative gallstones within 2 years. Gut microbiota metagenomic analyses showed group differences in abundance of 41 bacterial species, particularly abundance of Lactobacillaceae and Enterobacteriaceae in patients without gallstones. Subcutaneous adipose tissue transcriptomic analyses revealed four genes that were suppressed in gallstone patients compared with patients without gallstones. These baseline gene expression and gut microbiota composition differences might relate to protective mechanisms against gallstone formation after bariatric surgery. Moreover, baseline fasting blood samples of patients with postoperative gallstones showed increased levels of several bile acids. Overall, we revealed different genes and bacteria associated with gallstones than those previously reported in the general population, supporting the hypothesis that gallstone formation after bariatric surgery follows a different trajectory. Further research is necessary to confirm the involvement of the bile acids, adipose tissue activity, and microbial species observed here.

Complication rate after gastrostomy placement in children can be reduced by simple surgical steps
- 2023
-
In: Acta Pædiatrica. - : John Wiley & Sons. - 1651-2227 .- 0803-5253. ; 112:7, s. 1597-1604

Journal article (peer-reviewed)abstract
- AIM: To evaluate if the incidence of postoperative complications after gastrostomy placement is correlated to perioperative parameters or patient characteristics.METHODS: In this prospective observational study, children <18 years of age planned to receive a gastrostomy at partaking clinics between 2014 and 2019 were invited. Pre-, peri- and postoperative variables were collected and followed up 3 months postoperatively.RESULTS: Five hundred and eighty-two patients were included (median age: 26 months, median weight: 10.8 kg), mainly laparoscopic (52.0%) and push-PEG (30.2%) technique used. The incidence of complications was lower in the group of patients receiving a gastrostomy tube that was 2 mm longer than the gastrostomy canal (p < 0.001-0.025), and a thickness of 12 Fr (p < 0.001-0.009). These findings were confirmed by multivariate analysis also including operative technique, age and weight. Patients with oncological disease had significantly higher incidence of pain and infection but the lowest incidence of granulomas (p < 0.001-0.01).CONCLUSION: This study indicates that a 12 Fr gastrostomy tube that is 2 mm longer than the gastrostomy canal is correlated with the lowest incidence of postoperative complications the first 3 months after surgery. Oncological patients had the lowest incidence of granulomas which probably is related to chemotherapy.

- BACKGROUND & AIMS: Few studies have explored the link between childhood celiac disease and long-term psychiatric comorbidities. We performed a population-based cohort study of associations between childhood celiac disease and psychiatric disorders and investigated whether risk persists into adulthood.METHODS: We performed a nationwide study in Sweden using data from the ESPRESSO cohort. In this cohort, 19,186 children with a diagnosis of biopsy-verified celiac disease from 1973 through 2016 were identified from Sweden's 28 pathology departments. Each patient was matched with as many as 5 reference children (controls, n=94,249). Data on psychiatric disorders were obtained from the patient register. We used Cox proportional modeling to estimate hazard ratios (HRs).RESULTS: During a median follow-up time of 12.3 years, 3174 children (16.5%) with celiac disease received a new diagnosis of a psychiatric disorder, compared with 13,286 controls (14.1%). Corresponding incidence rates were 12.2 per 1000 person-years (95% Cl, 11.8-12.7) vs 10.3 per 1000 person-years (95% Cl, 10.2-10.5). Childhood celiac disease was associated with a 19% increase in risk of any psychiatric disorder (95% Cl, 1.14-1.23); the increase in risk was observed in all childhood age groups. The highest HRs were seen in the first year after celiac diagnosis (HR, 1.70; 95% Cl, 1.41-2.05). The risk increase persisted into adulthood (older than 18 years: HR, 1.11; 95% Cl, 1.04-1.17). We found increased risks of mood disorders (HR, 1.20; 95% CI, 1.12-1.28), anxiety disorders (HR, 1.12; 95% CI, 1.06-1.19), eating disorders (HR, 1.34; 95% CI, 1.18-1.51), attention deficit hyperactivity disorder (HR, 1.29; 95% CI, 1.20-1.39), and autism spectrum disorder (HR, 1.47; 95% CI, 1.32-1.64). We found no statistically significant risk increase for psychotic disorders, psychoactive substance misuse, behavioral disorders, personality disorders, suicide attempt, or suicide. Celiac disease was also linked to an increased use of psychiatric drugs (HR, 1.34; 95% CI, 1.24-1.43). A conditional logistic regression found that psychiatric disorders were also more common prior to diagnosis of celiac disease (odds ratio, 1.56; 95% Cl, 1.39-1.76).CONCLUSIONS: Childhood celiac disease is associated with increased risk of subsequent psychiatric disorders, which persists into adulthood. Mental health surveillance should be integral in the care of celiac disease.

A nordic multicenter study on contemporary outcomes of pediatric short bowel syndrome in 208 patients
- 2023
-
In: Clinical Nutrition. - : Elsevier. - 0261-5614 .- 1532-1983. ; 42:7, s. 1095-1103

Journal article (peer-reviewed)abstract
- Background & aims: Despite advances in the management of short bowel syndrome related intestinal failure (SBS-IF), large-scale contemporary pediatric studies are scarce. The aim of this multicenter study was to assess key outcomes and clinical prognostic factors in a recent Nordic pediatric SBS-IF population.Methods: Patients with SBS-IF treated during 2010-2019, whose parenteral support (PS) started at age <1 year and continued >60 consecutive days were included and retrospectively reviewed. All six participating centers followed multidisciplinary SBS-IF management. Risk factors for PS dependency, intestinal failure associated liver disease (IFALD) and mortality were assessed with Cox regression and Kaplan Meier analyses. IFALD was defined with serum liver biochemistry levels.Results: Among 208 patients, SBS-IF resulted from NEC in 49%, gastroschisis w/wo atresia in 14%, small bowel atresia in 12%, volvulus in 11%, and other diagnoses in 14%. Median age-adjusted small bowel length was 43% (IQR 21-80%). After median follow up of 4.4 years (IQR 2.5-6.9), enteral autonomy was reached by 76%, none had undergone intestinal transplantation, and overall survival was 96%. Half of deaths (4/8) were caused by septic complications. Although biochemical cholestasis occurred only in 3% at latest follow-up and none of deaths were directly caused by IFALD, elevated liver biochemistry (HR 0.136; P = 0.017) and shorter remaining small bowel (HR 0.941; P = 0.040) predicted mortality. Shorter remaining small bowel and colon, and presence of end-ostomy were the main predictors of PS dependency, but not IFALD. Patients with NEC reached enteral autonomy more efficiently and had decreased incidence of IFALD compared to other etiologies.Conclusions: Although with current multidisciplinary management, prognosis of pediatric SBS is encouraging, septic complications and IFALD still associated with the remaining low mortality rate.

Real-world Follow-up Practice of Children With Coeliac Disease: A Cross-sectional Study From Western Sweden
- 2022
-
In: JPGN Reports. - : Wolters Kluwer. - 2691-171X. ; 3:2
-
Journal article (peer-reviewed)abstract
- Coeliac disease (CD) is one of the most common chronic diseases of childhood. Follow-up of CD aims to ensure dietary adherence and prevent disease complications, but there are few real-world data on how its management in children is conducted. This study aimed to survey the follow-up practice of pediatric CD in Western Sweden. Two web-based surveys were distributed to all 22 pediatric outpatient clinics rendering answers from 48 physicians and 12 dietitians. Overall, clinical practice was similar throughout the region and in line with national and international CD guidelines, including an annual to biannually follow-up frequency and dietary adherence assessment through unstructured interviewing and serology measurements. The study identified possible areas of improvement, such as implementing a formal transition process to adult care and the use of validated questionaries to assess dietary adherence. Additionally, a positive attitude towards electronic-health technologies (eHealth) as part of CD follow-up was identified.

Perfusion monitoring using laser speckle contrast imaging during endorectal pull-through for Hirschsprung's disease
- 2022
-
In: Journal of Pediatric Surgery Case Reports. - : Elsevier BV. - 2213-5766. ; 76, s. 1-4
-
Journal article (peer-reviewed)abstract
- Surgical treatment of Hirschsprung's disease commonly involves resection of the aganglionic segment of the colon and endorectal pull-through. Postoperative complications include anastomotic leakage and/or stricture, both believed to be caused by inadequate perfusion of the mobilized bowel or high tension in the anastomosis, but this has never been investigated. In this case, laser speckle contrast imaging (LSCI) was used for the first time to monitor colonic perfusion during endorectal pull-through. A 6-week-old child with a 24-cm aganglionosis underwent laparoscopic-assisted endorecto pull-through with mobilization of the left colonic flexure to be able to reach the anus. LSCI perfusion monitoring showed that perfusion was 41% in the tip of the colon without tension, and was reduced 17% by a stretching force of 2 N. In conclusion, perfusion of the colonic end can be monitored by LSCI during surgery for Hirschsprung's disease. This provides new opportunities to evaluate the effects of such surgical interventions in the future.

Risk of Delayed Discharge and Reoperation of Gastric Bypass Patients with Psychiatric Comorbidity : a Nationwide Cohort Study
- 2020

Journal article (peer-reviewed)abstract
- BackgroundGastric bypass (GBP) surgery is considered a safe and effective treatment for obesity. However, there is uncertainty regarding the impact of preexisting psychiatric comorbidity on GBP complications. We have investigated whether a psychiatric diagnosis before GBP surgery is associated with delayed discharge (the odds of being in the 90th percentile of length of stay) and rate of reoperation in a nationwide Swedish cohort.MethodsPatients undergoing GBP surgery during 2008–2012 were identified and followed up through the National Patient Register and the Prescribed Drug Register. Logistic regression models were fitted to the studied outcomes.ResultsAmong the 22,539 patients identified, a prior diagnosis of bipolar disorder, schizophrenia, depression, neurotic disorders, ADHD (attention deficit hyperactivity disorder), substance use disorder, eating disorder, personality disorder, or self-harm since 1997 (n = 9480) was found to be associated with delayed discharge after GBP surgery (odds ratio [OR] = 1.47, confidence interval [CI] 1.34–1.62), especially in patients with psychiatric hospitalization exceeding 1 week in the 2 years preceding GBP surgery (OR = 2.06, CI 1.30–3.28), compared with those not hospitalized within psychiatry. Likewise, patients with a prior psychiatric diagnosis were more likely to be reoperated within 30 days (OR = 1.25, CI 1.11–1.41), with twice the likelihood OR 2.23 (CI 1.26–3.92) for patients with psychiatric hospitalization of up to a week in the 2 years preceding GBP surgery, compared with patients who had not been hospitalized within psychiatry.ConclusionsA psychiatric diagnosis before GBP surgery was associated with delayed discharge and increased likelihood of reoperation within 30 days. Patients with a prior psychiatric diagnosis may, therefore, need additional attention and support.

Increased Mortality Persists after Treatment of Cushing's Disease: A Matched Nationwide Cohort Study
- 2022
-
In: Journal of the Endocrine Society. - : The Endocrine Society. - 2472-1972. ; 6:6
-
Journal article (peer-reviewed)abstract
- Context: Whether biochemical remission normalizes life expectancy in Cushing's disease (CD) patients remains unclear. Previous studies evaluating mortality in CD are limited by using the expected number of deaths in the background population instead of the actual number in matched controls. Objective and setting: To study mortality by time-to-event analysis in an unselected nationwide CD patient cohort. Design and participants: Longitudinal data from the Swedish Pituitary Register of 371 patients diagnosed with CD from 1991 to 2018 and information from the Swedish Cause of Death Register were evaluated. Four controls per patient (n = 1484) matched at the diagnosis date by age, sex, and residential area were included. Main outcome measures: Mortality and causes of death. Results: The median diagnosis age was 44 years (interquartile range 32-56), and the median follow-up was 10.6 years (5.7-18.0). At the 1-, 5-, 10-, 15-, and 20-year follow-ups, the remission rates were 80%, 92%, 96%, 91%, and 97%, respectively. Overall mortality was increased in CD patients compared with matched controls [hazard ratio (HR) 2.1 (95% CI 1.5-2.8)1. The HRs were 1.5 (1.02-2.2) for patients in remission at the last follow-up In = 303), 1.7 (1.03-2.8) for those in remission after a single pituitary surgery In = 177), and 5.6 (2.7-11.6) for those not in remission (n = 31). Cardiovascular diseases (32/66) and infections (12/66) were overrepresented causes of death. Conclusions: Mortality was increased in CD patients despite biochemical remission compared to matched controls. The study highlights the importance of careful comorbidity monitoring, regardless of remission status.
