- Abstract
A large percentage of apples are affected by internal disorders after long-term storage, which makes them unacceptable in the supply chain. CT imaging is a promising technique for in-line detection of these disorders. Therefore, it is crucial to understand how different disorders affect the image features that can be observed in CT scans. This paper presents a workflow for creating datasets of image pairs of photographs of apple slices and their corresponding CT slices. By having CT and photographic images of the same part of the apple, the complementary information in both images can be used to study the processes underlying internal disorders and how internal disorders can be measured in CT images. The workflow includes data acquisition, image segmentation, image registration, and validation methods. The image registration method aligns all available slices of an apple within a single optimization problem, assuming that the slices are parallel. This method outperformed optimizing the alignment separately for each slice. The workflow was applied to create a dataset of 1347 slice photographs and their corresponding CT slices. The dataset was acquired from 107 ‘Kanzi’ apples that had been stored in controlled atmosphere (CA) storage for 8 months. In this dataset, the distance between annotations in the slice photograph and the matching CT slice was, on average, 1.47 ± 0.40 mm. Our workflow allows collecting large datasets of accurately aligned photo-CT image pairs, which can help distinguish internal disorders with a similar appearance on CT. With slight modifications, a similar workflow can be applied to other fruits or MRI instead of CT scans.

Introduction: Molecular profiling of NSCLC is essential for optimising treatment decisions, but often incomplete. We assessed the efficacy of protocolised molecular profiling in the current standard-of-care (SoC) in a prospective observational study in the Netherlands and measured the effect of providing standardised diagnostic procedures. We also explored the potential of plasma-based molecular profiling in the primary diagnostic setting. Methods: This multi-centre prospective study was designed to explore the performance of current clinical practice during the run-in phase using local SoC tissue profiling procedures. The subsequent phase was designed to investigate the extent to which comprehensive molecular profiling (CMP) can be maximized by protocolising tumour profiling. Successful molecular profiling was defined as completion of at least EGFR and ALK testing. Additionally, PD-L1 tumour proportions scores were explored. Lastly, the additional value of centralised plasma-based testing for EGFR and KRAS mutations using droplet digital PCR was evaluated. Results: Total accrual was 878 patients, 22.0% had squamous cell carcinoma and 78.0% had non-squamous NSCLC. Stage I-III was seen in 54.0%, stage IV in 46.0%. Profiling of EGFR and ALK was performed in 69.9% of 136 patients included in the run-in phase, significantly more than real-world data estimates of 55% (p<0.001). Protocolised molecular profiling increased the rate to 77.0% (p = 0.049). EGFR and ALK profiling rates increased from 77.9% to 82.1% in non-squamous NSCLC and from 43.8% to 57.5% in squamous NSCLC. Plasma-based testing was feasible in 98.4% and identified oncogenic driver mutations in 7.1% of patients for whom tissue profiling was unfeasible. Conclusion: This study shows a high success rate of tissue-based molecular profiling that was significantly improved by a protocolised approach. Tissue-based profiling remains unfeasible for a substantial proportion of patients. Combined analysis of tumour tissue and circulating tumour DNA is a promising approach to allow adequate molecular profiling of more patients. [ABSTRACT FROM AUTHOR]

- Abstract
Growth of fruit and fruit size is of major importance for growers. Growth in size during cell expansion is well known (adapted van Bertalanffy model) and well applied taking care of the ever-present variation. Explained parts reach well over 98%. What is not very well understood is the increase in number of cells and the associated size increase, just after fruit set. It is (for the time being) just not feasible to measure these small fruit (<5 mm) on an individual level. As a consequence, the von Bertalanffy model does not cover the behaviour right after fruit set. Very rare reports, however, indicate a gradual increase in number of cells, which keep subsequently growing in size during the cell expansion period. A kinetic mechanism is presented that includes both these concurrent processes, however, consisting of six reactions, this model becomes exceedingly complex. Hence, an analytical solution is not available. Simulation using numerical integration with various parameter values will be presented. The general behaviour is as expected, roughly as an asymmetric sigmoidal. As a comparison, the well know Richards’ curve, frequently used to describe growth, is hard to apply as an analysing tool. Moreover, this function has no relation whatsoever with any kinetic mechanism. A new simplified kinetic mechanism that is suitable for data analysis is presented based on conversion of a substrate by an enzyme that increases according to an autocatalytic reaction. The resulting analytical solution can be used to analyse simulated size data, including biological variation. All simulated data on growth size fitted extremely well in the asymmetrical logistic model, with explained parts well over 99%. Behaviour of the growth mechanism, and analysis results of simulated data the developed asymmetrical sigmoidal function will be presented and discussed.

- Abstract
A core challenge in global change biology is to predict how species will respond to future environmental change and to manage these responses. To make such predictions and management actions robust to novel futures, we need to accurately characterize how organisms experience their environments and the biological mechanisms by which they respond. All organisms are thermodynamically connected to their environments through the exchange of heat and water at fine spatial and temporal scales and this exchange can be captured with biophysical models. Although mechanistic models based on biophysical ecology have a long history of development and application, their use in global change biology remains limited despite their enormous promise and increasingly accessible software. We contend that greater understanding and training in the theory and methods of biophysical ecology is vital to expand their application. Our review shows how biophysical models can be implemented to understand and predict climate change impacts on species' behavior, phenology, survival, distribution, and abundance. It also illustrates the types of outputs that can be generated, and the data inputs required for different implementations. Examples range from simple calculations of body temperature at a particular site and time, to more complex analyses of species' distribution limits based on projected energy and water balances, accounting for behavior and phenology. We outline challenges that currently limit the widespread application of biophysical models relating to data availability, training, and the lack of common software ecosystems. We also discuss progress and future developments that could allow these models to be applied to many species across large spatial extents and timeframes. Finally, we highlight how biophysical models are uniquely suited to solve global change biology problems that involve predicting and interpreting responses to environmental variability and extremes, multiple or shif

- Abstract
Aim: Cardiac diseases remain a leading cause of cardiovascular disease (CVD) related hospitalisation and mortality. That is why research to improve our understanding of pathophysiological processes underlying cardiac diseases is of great importance. There is a strong need for healthy and diseased human cardiac tissue and related clinical data to accomplish this, since currently used animal and in vitro disease models do not fully grasp the pathophysiological processes observed in humans. This design paper describes the initiative of the Netherlands Heart Tissue Bank (NHTB) that aims to boost CVD-related research by providing an open-access biobank. Methods: The NHTB, founded in June 2020, is a non-profit biobank that collects and stores biomaterial (including but not limited to myocardial tissue and blood samples) and clinical data of individuals with and without previously known cardiac diseases. All individuals aged ≥ 18 years living in the Netherlands are eligible for inclusion as a potential future donor. The stored samples and clinical data will be available upon request for cardiovascular researchers. Conclusion: To improve the availability of cardiac tissue for cardiovascular research, the NHTB will include extensive (cardiac) biosamples, medical images, and clinical data of donors with and without a previously known cardiac disease. As such, the NHTB will function as a translational bridge to boost a wide range of cardiac disease-related fundamental and translational studies.

Objective: To investigate the oncological safety and potential cost savings of selective histopathological examination after appendectomy. Background: The necessity of routine histopathological examination after appendectomy has been questioned, but prospective studies investigating the safety of a selective policy are lacking. Methods: In this multicenter, prospective, cross-sectional study, inspection and palpation of the (meso)appendix was performed by the surgeon in patients with suspected appendicitis. The surgeon's opinion on additional value of histopathological examination was reported before sending all specimens to the pathologist. Main outcomes were the number of hypothetically missed appendiceal neoplasms with clinical consequences benefiting the patient (upper limit two-sided 95% confidence interval below 3:1000 considered oncologically safe) and potential cost savings after selective histopathological examination. Results: Seven thousand three hundred thirty-nine patients were included. After a selective policy, 4966/7339 (67.7%) specimens would have been refrained from histopathological examination. Appendiceal neoplasms with clinical consequences would have been missed in 22/4966 patients. In 5/22, residual disease was completely resected during additional surgery. Hence, an appendiceal neoplasm with clinical consequences benefiting the patient would have been missed in 1.01:1000 patients (upper limit 95% confidence interval 1.61:1000). In contrast, twice as many patients (10/22) would not have been exposed to potential harm due to re-resections without clear benefit, whereas consequences were neither beneficial nor harmful in the remaining seven. Estimated cost savings established by replacing routine for selective histopathological examination were 725,400 per 10,000 patients. Conclusions: Selective histopathological examination after appendectomy for suspected appendicitis is oncologically safe and will likely result in a reduction of pathologists' workload, less costs, and fewer re-resections without clear benefit.

Introduction: Haemorrhoidal disease (HD) is a common condition with significant epidemiologic and economic implications. While it is possible to treat symptomatic grade 1–2 haemorrhoids with rubber band ligation (RBL) or sclerotherapy (SCL), the effectiveness of these treatments compatible with current standards has not yet been investigated with a randomised controlled trial. The hypothesis is that SCL is not inferior to RBL in terms of symptom reduction (patient-related outcome measures (PROMs)), patient experience, complications or recurrence rate. Methods and analysis: This protocol describes the methodology of a non-inferiority, multicentre, randomised controlled trial comparing rubber band ligation and sclerotherapy for symptomatic grade 1–2 haemorrhoids in adults (> 18 years). Patients are preferably randomised between the two treatment arms. However, patients with a strong preference for one of the treatments and refuse randomisation are eligible for the registration arm. Patients either receive 4 cc Aethoxysklerol 3% SCL or 3 × RBL. The primary outcome measures are symptom reduction by means of PROMs, recurrence and complication rates. Secondary outcome measures are patient experience, number of treatments and days of sick leave from work. Data are collected at 4 different time points. Discussion: The THROS trial is the first large multicentre randomised trial to study the difference in effectivity between RBL and SCL for the treatment of grade 1–2 HD. It will provide information as to which treatment method (RBL or SCL) is the most effective, gives fewer complications and is experienced by the patient as the best option.

Purpose: Hospitals performing a certain bariatric procedure in high volumes may have better outcomes. However, they could also have worse outcomes for some patients who are better off receiving another procedure. This study evaluates the effect of hospital preference for a specific type of bariatric procedure on their overall weight loss results. Methods: All hospitals performing bariatric surgery were included from the nationwide Dutch Audit for Treatment of Obesity. For each hospital, the expected (E) numbers of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB) were calculated given their patient-mix. These were compared with the observed (O) numbers as the O/E ratio in a funnel plot. The 95% control intervals were used to identify outlier hospitals performing a certain procedure significantly more often than expected given their patient-mix (defined as hospital preference for that procedure). Similarly, funnel plots were created for the outcome of patients achieving ≥ 25% total weight loss (TWL) after 2 years, which was linked to each hospital's preference. Results: A total of 34,558 patients were included, with 23,154 patients completing a 2-year follow-up, of whom 79.6% achieved ≥ 25%TWL. Nine hospitals had a preference for RYGB (range O/E ratio [1.09–1.53]), with 1 having significantly more patients achieving ≥ 25%TWL (O/E ratio [1.06]). Of 6 hospitals with a preference for SG (range O/E ratio [1.10–2.71]), one hospital had significantly fewer patients achieving ≥ 25%TWL (O/E ratio [0.90]), and from two hospitals with a preference for OAGB (range O/E ratio [4.0–6.0]), one had significantly more patients achieving ≥ 25%TWL (O/E ratio [1.07]). One hospital had no preference for any procedure but did have significantly more patients achieving ≥ 25%TWL (O/E ratio [1.10]). Conclusion: Hospital preference is not consistently associated with better overall weight loss results. This suggests that even though experience with a procedure may be slightly less in hospitals not having a preference, it is still sufficient to achieve similar weight loss outcomes when surgery is provided in centralized high-volume bariatric institutions.

- Abstract
Background: To investigate the incidence, demographic characteristics, etiologies, surgical interventions, hospital stays, and neurologic outcomes associated with watersport-related traumatic spinal cord injuries (TSCI) in New Zealand., Methods: Retrospective study collected data from New Zealand's two spinal rehabilitation units, the Auckland Spinal Rehabilitation Unit (ASRU) and the Burwood Spinal Unit (BSU). It included adults aged over 16 years, between January 2007 and December 2021 with new TSCI secondary to traumatic watersport activities. Variables assessed include type of water-related activity, length of hospital stay, surgical intervention and neurologic outcomes, categorized by the American Spinal Injury Association (ASIA) impairment scale., Results: Data from 80 patients were analysed. The mean annual incidence of water-related TSCI was 1.141 per 1,000,000 per year, predominantly affecting males (68 males vs. 12 females) with a mean age of 31.1 years. Maori had the highest incidence rate (2.02 per 1,000,000). Diving was the leading cause of TSCI (57 cases), particularly from pool and wharf accidents. Most injuries occurred between December and March. Surgical intervention was performed in 89% of cases. The average hospital stay was 93.65 days, with the cervical region being the most commonly affected (85.1%)., Conclusions: Watersport-related TSCI in New Zealand predominantly affects the young, Maori and males, with cervical spine injuries, particularly from diving accidents being most common. Seasonal trends suggest a need for targeted prevention during warmer months. These findings provide insights for public health initiatives, clinical management and the development of prevention strategies., (© 2025 Royal Australasian College of Surgeons.)

- Abstract
Purpose: Patient-reported outcomes are important as obesity is a chronic disease with a substantial impact. A multidisciplinary task force selected six scales (48 questions) from the validated BODY-Q questionnaire. This subset was gradually introduced and evaluated in a mandatory nationwide registry. The focus was to assess the scale's module results and its feasibility in a quality registry., Materials and Methods: All Dutch patients undergoing bariatric surgery between 2019 and 2022 were selected. Completed questionnaires of RAND-36, EQ-5D-5L, and BODY-Q were reviewed with baseline and 1-year results. Uni- and multivariable regression analyses were performed to assess the relationship between baseline characteristics and quality of life scores over time., Results: A total of 10,972 patients completed at least one BODY-Q scale. The lowest score was on the body image scale preoperatively (28.2, SD 20.9) and the highest on the social scale postoperatively (76.2, SD 18.8). A representative group of 510 patients with repeated measurements showed the most improvement on the body image scale (+ 32.2) followed by physical function (+ 26.3). Multivariable linear regression analysis showed a significant influence, primarily for gender, age, and BMI on BODY-Q scores. Score improvement for BODY-Q was mainly driven by weight loss, while EQ-5D-5L and RAND-36 showed no clear pattern. Comparing the three questionnaires showed significant correlations for physical and social function only., Conclusion: The BODY-Q obesity module demonstrates potential as a relevant PROM for inclusion in a quality registry. BODY-Q scores provide a foundation for future research, with notable improvements in quality of life observed, particularly in the body image and physical function scales., Competing Interests: Declarations.

- Abstract
Aim: The aim of this study was to assess Dutch surgical practice and outcomes for acute pilonidal abscess., Method: Patients with pilonidal sinus disease (PSD) who underwent surgical treatment between 1 March 2020 and 1 March 2021 at 36 participating hospitals were included in a prospective observational cohort study. For the present study, only patients with an acute abscess were included for analysis. Outcomes included symptoms, wound healing, time to resume daily activities and complications. Follow-up was 1 year and included questionnaires on recurrent abscesses, symptomatic chronic PSD, quality of life and patient-reported experience measures., Results: Of 681 included patients, 208 presented with an acute pilonidal abscess. Incision and drainage (I&D) was performed in 205 of these patients (99%). The wound healing rate after I&D was 42.2% at the outpatient clinic, with a median time to closure of 43 days. The complication rate was 4.4%. One-year questionnaires were completed by 158 out of 205 patients (77.1%). Fifteen patients (7.3%) had a recurrent abscess within 1 year. The symptomatic chronic PSD rate was 8.8%., Conclusion: Of all the patients presenting with PSD in this prospective national study cohort, 30% had a pilonidal abscess. Incision and drainage showed a low complication rate but successful wound healing in less than half of the patients. The study showed that 91.2% of patients did not undergo additional surgical treatment for symptomatic chronic PSD within 1 year of follow-up., (© 2024 The Author(s).

- Abstract
Aim: Managing pilonidal sinus disease (PSD) remains challenging due to high recurrence rates and morbidity associated with treatment. The aim of this study was to evaluate the outcomes one year after surgical treatment for chronic PSD in the Netherlands., Method: Patients with PSD who underwent surgical treatment between March 1, 2020, and March 1, 2021, at 36 participating hospitals were included in a prospective observational cohort study. For the present study, only patients with chronic PSD were included for analysis. One-year after surgical treatment for PSD, all patients received questionnaires on wound healing, quality of life (QoL), and patient reported experience measures (PREMs). Primary outcome was recurrence rate. Secondary outcomes included QoL and PREMs., Results: Of 681 included patients, 405 patients presented with chronic PSD and underwent surgical treatment. One-year questionnaires were completed by 289 out of 405 patients (71.4%). Patients underwent either excision with secondary wound healing (ESW, n = 73), excision with midline closure (EMC, n = 21), off-midline closure (OMC, n = 17), or a minimally invasive technique (MIT, n = 178). Patient-reported recurrence rates after ESW, EMC, OMC and MIT were 21.5%, 25%, 6.7% and 30.6%, respectively. Pain/discomfort and anxiety/depression were the most frequently reported problems affecting QoL. Patients that underwent OMC were satisfied the most with the care provided., Conclusion: This study demonstrates variation in recurrence rates among surgical procedures for PSD. The highest rates were observed in the MIT and EMC group, while the OMC group exhibited the lowest rate. QoL outcomes differed among the surgical techniques. Patient satisfaction appears highest in the OMC group., (© 2024 Association of Coloproctology of Great Britain and Ireland.)

- Abstract
Objectives: The aims were to (1) prospectively observe the incidence of bone marrow oedema in asymptomatic adult male domestic professional cricketers during a season and evaluate its relationship to the development of lumbar bone stress injury and (2) further understand the practicalities of implementing a Magnetic Resonance Imaging-based screening program to prevent lumbar bone stress injury in New Zealand cricket., Design: Prospective observational cohort., Methods: Adult male pace bowlers received 6-weekly pre-planned Magnetic Resonance Imaging scans over a single season to determine the presence and intensity of bone marrow oedema in the posterior vertebral arches of the lumbar spine. The participants bowling volume and back pain levels were monitored prospectively., Results: 22 participants (mean age 25.3 years (range 20-32 years)) completed all 4 scans. Ten participants had a prior history of lumbar bone stress injury. Ten participants (45 %, 95 % confidence interval 24-68 %) had bone marrow oedema evident on at least one scan, with 9 (41 %) participants recording a bone marrow oedema intensity ≥ 2 and 5 (23 %) participants demonstrated an intensity ≥ 3. During the study one participant was diagnosed with a lumbar bone stress reaction. No participants developed a lumbar bone stress fracture., Conclusions: Due to the lower incidence of lumbar bone stress injuries in adult bowlers coupled with uncertainty over appropriate threshold values for bone marrow oedema intensity, implementation of a resource intense screening program aimed at identifying adult domestic cricketers at risk of developing a lumbar bone stress injury is not currently supported., Competing Interests: Declaration of interest statement The authors have no conflict of interest to declare.

- Abstract
Accurate anti-drug antibody (ADA) measurements in patient sera requires dissociation of ADA-drug complexes combined with sensitive and specific ADA detection. Bridging type immunoassays are often used despite several disadvantages associated with this approach. A good drug-tolerant alternative is the acid-dissociation radioimmunoassay (ARIA), but this method is not easily implemented in most labs as specialized facilities are required for working with radioactive materials. We describe an innovative method for ADA detection that combines the advantages of antigen binding tests like the ARIA with the convenience of regular immunoassays. This acid-dissociation lanthanide-fluorescence immunoassay (ALFIA) involves dissociation of ADA-drug complexes, followed by binding to an europium-labeled drug derivative and subsequently an IgG pulldown on Sepharose beads. After europium elution, detection is achieved by measuring time-resolved fluorescence originating from europium chelate complexes. We measured anti-adalimumab ADA levels in sera of 94 rheumatoid arthritis patients using the ALFIA and showed this method to be highly drug tolerant, sensitive and specific for anti-adalimumab ADAs., Competing Interests: Declaration of Competing Interest TR received funding for research from Genmab and consultancy fees from Novartis., (Copyright © 2023 Elsevier B.V.

- Abstract
A core challenge in global change biology is to predict how species will respond to future environmental change and to manage these responses. To make such predictions and management actions robust to novel futures, we need to accurately characterize how organisms experience their environments and the biological mechanisms by which they respond. All organisms are thermodynamically connected to their environments through the exchange of heat and water at fine spatial and temporal scales and this exchange can be captured with biophysical models. Although mechanistic models based on biophysical ecology have a long history of development and application, their use in global change biology remains limited despite their enormous promise and increasingly accessible software. We contend that greater understanding and training in the theory and methods of biophysical ecology is vital to expand their application. Our review shows how biophysical models can be implemented to understand and predict climate change impacts on species' behavior, phenology, survival, distribution, and abundance. It also illustrates the types of outputs that can be generated, and the data inputs required for different implementations. Examples range from simple calculations of body temperature at a particular site and time, to more complex analyses of species' distribution limits based on projected energy and water balances, accounting for behavior and phenology. We outline challenges that currently limit the widespread application of biophysical models relating to data availability, training, and the lack of common software ecosystems. We also discuss progress and future developments that could allow these models to be applied to many species across large spatial extents and timeframes. Finally, we highlight how biophysical models are uniquely suited to solve global change biology problems that involve predicting and interpreting responses to environmental variability and extremes, multiple or shifting constraints, and novel abiotic or biotic environments., (© 2022 The Authors.

- Abstract
Background: The aim was to evaluate the cost-effectiveness and cost-utility of ursodeoxycholic acid (UDCA) prophylaxis for the prevention of symptomatic gallstone disease after Roux-en-Y gastric bypass (RYGB) in patients without gallstones before surgery., Methods: Data from a multicentre, double-blind, randomized placebo-controlled superiority trial were used. Patients scheduled for laparoscopic RYGB or sleeve gastrectomy were randomized to receive 900 mg UDCA or placebo for 6 months. Indicated by the clinical report, prophylactic prescription of UDCA was evaluated economically against placebo from a healthcare and societal perspective for the subgroup of patients without gallstones before surgery who underwent RYGB. Volumes and costs of in-hospital care, out-of-hospital care, out-of-pocket expenses, and productivity loss were assessed. Main outcomes were the costs per patient free from symptomatic gallstone disease and the costs per quality-adjusted life-year (QALY)., Results: Patients receiving UDCA prophylaxis were more likely to remain free from symptomatic gallstone disease (relative risk 1.06, 95 per cent c.i. 1.02 to 1.11; P = 0.002) compared with patients in the placebo group. The gain in QALYs, corrected for a baseline difference in health utility, was 0.047 (95 per cent bias-corrected and accelerated (Bca) c.i. 0.007 to 0.088) higher (P = 0.022). Differences in costs were -€356 (95 per cent Bca c.i. €-1573 to 761) from a healthcare perspective and -€1392 (-3807 to 917) from a societal perspective including out-of-pocket expenses and productivity loss, both statistically non-significant, in favour of UDCA prophylaxis. The probability of UDCA prophylaxis being cost-effective was at least 0.872., Conclusion: UDCA prophylaxis after RYGB in patients without gallstones before surgery was cost-effective., (© The Author(s) 2022.

- Abstract
Background: Depression is associated with lower quality of life and increased risk of mortality. The prevalence of depression in chronic dialysis patients, as well as in patients with diabetes, is more than 20%. It is debated whether use of beta-blockers increases the risk of depression. Therefore, we examined in chronic dialysis patients with and without diabetes, the association between beta-blockers and depressive symptoms., Methods: Data were collected from the DIVERS-I study, a multicentre prospective cohort among chronic dialysis patients in the Netherlands. Depressive symptoms were assessed with the Beck Depression Inventory (BDI-II). We defined depressive symptoms as a BDI-II score ⩾16. The cross-sectional association at baseline between depressive symptoms and beta-blocker use in chronic dialysis patients, was studied by multivariable logistic regression adjusted for potential confounders., Results: We included 684 chronic dialysis patients, of whom 43% had diabetes mellitus, and 57% used a beta-blocker of which 97% were lipophilic. After multivariable adjustment, the OR (95% CI) for depressive symptoms in patients with compared to without diabetes was 1.41 (1.00-1.98), and in beta-blocker users compared to non-users 1.12 (0.80-1.56), respectively. Dialysis patients with diabetes and beta-blocker use compared to those without diabetes and not using beta-blockers had an OR of 1.73 (1.12-2.69) for depressive symptoms. The association was stronger in dialysis patients with diabetes and lipophilic beta-blocker use with an OR of 1.77 (1.14-2.74)., Conclusions: We found a possible association between lipophilic beta-blocker use and depressive symptoms in chronic dialysis patients with diabetes., Competing Interests: Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

- Abstract
Background: Ursodeoxycholic acid (UDCA) reduces symptomatic gallstone disease after Roux-en-Y gastric bypass (RYGB). The beneficial effect of UDCA is reduced by poor adherence., Objectives: We aimed to identify factors associated with poor adherence to UDCA or placebo after bariatric surgery., Setting: Outpatient clinic and department for bariatric surgery in three hospitals in the Netherlands., Methods: Patients in the multicenter, double-blind, randomized, placebo-controlled UPGRADE trial were assessed for adherence to 900 mg UDCA or placebo for 6 months through a pill count, inquiries during follow-up, and a questionnaire. Poor adherence was defined as the usage of <300 of 364 pills within a maximum of 8 months postoperatively. Multivariable logistic regression analysis was used to identify factors contributing to poor adherence., Results: In total, 967 patients were included (mean age [standard deviation (SD)]: 45.1 [11.1] years; female: 772 [80%]; RYGB: 889 [92%]; sleeve gastrectomy: 78 [8%]), of whom 357 (37%) were poor adherers. Factors associated with poor adherence were age (OR .97; 95% confidence interval [CI] .96-.98, a decrease in age increases the odds for poor adherence), foreign origin (odds ratio [OR] 2.07; 95%CI 1.50-2.84), unemployment (OR 1.73; 95%CI 1.28-2.34), and sleeve gastrectomy (OR 1.79; 95%CI 1.06-3.01). Furthermore, a difference in adherence status was also noted for the centers of surgery., Conclusions: The adherence rate to UDCA and placebo in the UPGRADE trial was suboptimal. Several factors were independently associated with poor adherence. Our findings can help to identify patients who may benefit from extra guidance to improve adherence., (Copyright © 2022.

- Abstract
Purpose: Patients who undergo bariatric surgery are at risk for developing cholesterol gallstones. We aimed to identify risk factors that are associated with symptomatic gallstone disease and gallstone formation after bariatric surgery., Materials and Methods: We included participants of the UPGRADE trial, a multicenter randomized placebo-controlled trial on the prevention of symptomatic gallstone disease with ursodeoxycholic acid (UDCA) after bariatric surgery. The association between patient characteristics and symptomatic gallstone disease, and gallstone formation was evaluated using logistic regression analysis., Results: Of 959 patients, 78 (8%) developed symptomatic gallstone disease within 24 months. Risk factors were the presence of a pain syndrome (OR 2.07; 95% CI 1.03 to 4.17) and asymptomatic gallstones before surgery (OR 3.15; 95% CI 1.87 to 5.33). Advanced age (OR 0.95; 95% CI 0.93 to 0.97) was protective, and UDCA prophylaxis did not reach statistical significance (OR 0.64; 95% CI 0.39 to 1.03). No risk factors were identified for gallstone formation, whereas advanced age (OR 0.98; 95% CI 0.96 to 1.00), statin use (OR 0.42; 95% CI 0.20 to 0.90), and UDCA prophylaxis (OR 0.47; 95% CI 0.30 to 0.73) all reduced the risk., Conclusion: Young patients with a preoperative pain syndrome and/or asymptomatic gallstones before bariatric surgery are at increased risk for symptomatic gallstone disease after surgery. Whether statins, either alone or in combination with UDCA prophylaxis, can further reduce the burden of gallstones after bariatric surgery should be investigated prospectively., (© 2022.

- Abstract
Background: An emerging and promising minimally invasive treatment for pilonidal disease (PD) is sinus laser-assisted closure (SiLaC®). Previous studies have shown encouraging results concerning safety, patient satisfaction, wound healing and acceptable recurrence rates. This study investigated outcomes for a large cohort of PD patients treated with SiLaC®., Methods: A multicentre cohort study with a prospective design and partial retrospective data collection for patients with PD treated with SiLaC® in three hospitals in the Netherlands (Albert Schweitzer Hospital, Flevoziekenhuis and Medical Centre Zuiderzee) from January 1st 2017 to March 1st 2020. The primary outcome was recurrence. Secondary outcomes were incidence of complete wound closure, time until wound closure, postoperative complications, ability to perform daily activities and reported patient satisfaction., Results: A total of 311 patients were included with a median follow-up of 10 months (range 1-52 months). The recurrence rate after one SiLaC® treatment was 26% with 7% experiencing incomplete wound closure, resulting in an initial success rate of 66% after one SiLaC® procedure. This increased to 92% and 98% after two and three SiLaC® procedures, respectively. Mean time until wound closure was 6 weeks (range 1-24 weeks). Seven patients (2%) were still unsuccessfully treated after three SiLaC® treatments and required additional and extensive surgery. Mean time to perform regular daily activities including working was 6 days (range 0-42 days) and the vast majority of patients (84%) did not require painkillers or only paracetamol. Twelve patients (4%) developed a postoperative wound infection. The mean satisfaction score was 9 (range 5-10)., Conclusions: SiLaC® is a promising minimally invasive treatment for PD with high patient satisfaction and an acceptable success rate. These results suggest that SiLaC® could be used as a safe and effective primary treatment for PD., (© 2021. Springer Nature Switzerland AG.)
