ABSTRACT

PURPOSE: Weight regain after Roux-en-Y gastric bypass (RYGB) is associated with worsening of liver outcomes. However, the effect of transoral outlet reduction (TORe) on liver fibrosis in RYGB patients with weight regain and possible advanced fibrosis remains unknown.

MATERIALS AND METHODS: This was a retrospective analysis of prospectively collected data of RYGB patients who underwent TORe for weight regain. Only patients with possible advanced fibrosis were included. TORe was performed using either an endoscopic suturing device (S-TORe) or plication device (P-TORe) to reduce the gastrojejunal anastomosis (GJA) and pouch sizes. Primary outcomes included changes in non-invasive tests (NITs) for fibrosis at 6-12 months. Secondary outcomes included weight loss and changes in insulin resistance and lipid profile at 6-12 months.

RESULTS: Fifty RYGB patients were included. Baseline age and BMI were 55 ± 11 years and 40.1 ± 7.3 kg/m². Baseline GJA and pouch sizes were 20 ± 7 mm and 5 ± 2 cm, respectively. Thirty patients (60%) underwent S-TORe and 20 patients (40%) underwent P-TORe. At 12 months following TORe, there were statistically significant improvements in NITs for fibrosis, including ALT, AST and FIB-4. There was a trend towards significant improvement in liver stiffness measurement on transient elastography. Patients experienced 8.8 ± 11.2% total weight loss (TWL) (p < 0.0001), with 60% experiencing at least 10% TWL. Additionally, there was a significant improvement in HbA1c and a trend toward significant improvement in Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), suggestive of improved insulin sensitivity.

CONCLUSION: TORe is associated with an improvement in hepatic fibrosis in patients with NAFLD and possible advanced fibrosis.

ABSTRACT

Precision medicine has been a global trend of medical development, wherein cancer diagnosis plays an important role. With accurate diagnosis of cancer, we can provide patients with appropriate medical treatments for improving patients’ survival. Since disease developments involve complex interplay among multiple factors such as gene-gene interactions, cancer classifications based on microarray gene expression profiling data are expected to be effective, and hence, have attracted extensive attention in computational biology and medicine. However, when using genomic data to build a diagnostic model, there exist several problems to be overcome, including the high-dimensional feature space and feature contamination. In this paper, we propose using the overlapping group screening (OGS) approach to build an accurate cancer diagnosis model and predict the probability of a patient falling into some disease classification category in the logistic regression framework. This new proposal integrates gene pathway information into the procedure for identifying genes and gene-gene interactions associated with the classification of cancer outcome groups. We conduct a series of simulation studies to compare the predictive accuracy of our proposed method for cancer diagnosis with some existing machine learning methods, and find the better performances of the former method. We apply the proposed method to the genomic data of The Cancer Genome Atlas related to lung adenocarcinoma (LUAD), liver hepatocellular carcinoma (LHC), and thyroid carcinoma (THCA), to establish accurate cancer diagnosis models.

ABSTRACT

OBJECTIVE: Endoscopic cauterization is an effective method for treating pyriform sinus fistula (PSF). However, these approaches sometimes result in a higher failure rate. We present an effective technique utilizing suture combined with chemocauterization as first-line treatment in patients with PSF and evaluate the safety and efficacy of its use in 126 patients.

STUDY DESIGN: Retrospective study.

SETTING: Tertiary referral center.

METHODS: Retrospective case review of patients treated between March 2012 and June 2021 at our institution with descriptive statistical analysis.

RESULTS: A total of 126 patients with PSF were included in this study with a mean age of 14.7 years. There was no sex predilection. The majority of patients presented with a left-sided neck lesion (89.7%). Ten patients presented following prior attempts at the surgery of the PSF at another institution; 8 via open surgery and 2 following endoscopic CO₂ laser cauterization; other patients only had a history of repeat incision and drainage or antibiotic treatment. The success rate of obliteration of the internal opening was 96.83% after a single treatment without complications. Following reoperation, a successful outcome was achieved in the remaining 4 patients. Length of stay ranged from 10 to 14 days. No recurrences occurred within 12 to 120 months followed-up.

CONCLUSION: Endoscopic suture combined with chemocauterization is a safe and effective treatment of PSF. Surgery can be performed during the acute cervical inflammatory period without increased risk of complication or recurrence, however, patients found to have acute changes affecting the pyriform sinus should be treated with a staged surgery strategy.

ABSTRACT

INTRODUCTION: It is unclear if sex differences exist in cognitive disease progression in mild cognitive impairment (MCI) and dementia associated with atrial fibrillation (AF).

METHODS: Using a variety of statistical methods, we examined sex differences between AF and neuropsychological tests and cognitive disease progression, using the National Alzheimer’s Coordinating Center data (N = 43,630).

RESULTS: AF is associated with higher odds of dementia (odds ratio [OR] 3.00, 95% confidence interval [CI] [1.22, 7.37] in women and MCI in women (OR 3.43, 95% CI [1.55, 7.55]) versus men. Women with AF and normal baseline cognition had a higher risk of disease progression (hazard ratio [HR] 1.26, 95% CI [1.06, 1.50]) from normal to MCI and from MCI to vascular dementia (HR3.27, 95% CI [1.89, 5.65]) than men with AF or men and women without AF.

DISCUSSION: AF was associated with more rapid progression to MCI and dementia in women, but more research is needed to confirm these findings.

ABSTRACT

BACKGROUND: Evidence on the longitudinal associations between serum uric acid (SUA) and stroke was limited and yielded inconsistent conclusions. We aimed to investigate the associations of cumulative SUA (cumSUA), incorporating the time course of cumSUA accumulation, with the risk of stroke.

METHODS: The prospective cohort study enrolled 50 871 participants from Kailuan, China. CumSUA from 2006 to 2010 was derived by calculating the means of SUA values between consecutive examinations and multiplying by time intervals between visits. Time course of cumSUA accumulation was categorized as the slope of SUA versus time or by splitting the overall accumulation into an early (cumSUA_06-08) and late accumulation (cumSUA_08-10). Participants were classified by cumSUA quartiles, SUA slope (negative versus positive), and the combined median cumSUA (1105.21 μmol/L×year) with SUA slope, respectively. The associations with incident stroke between 2010 and 2019 were evaluated with competing risk model.

RESULTS: During a median follow-up of 9.02 years, 2217 cases of incident stroke were identified. In the multivariable-adjusted model, a higher risk of stroke was observed in participants with the highest quartile versus the lowest quartile of cumSUA (subdistribution hazard ratio, 1.15 [95% CI, 1.01-1.31]), and those with a negative versus positive SUA slope (subdistribution hazard ratio, 1.09 [95% CI, 1.01-1.19]). Consistently, a later accumulation of SUA was not associated with the risk of stroke after adjustment for an early accumulation, indicating early accumulation may contribute more to the risk of stroke than later accumulation. When cumSUA was incorporated with its time course, those with changes in cumSUA suggesting early accumulation had elevated risk of stroke (subdistribution hazard ratio, 1.17 [95% CI, 1.03-1.33]). Similar results were observed for ischemic stroke.

CONCLUSIONS: Incident stroke risk was associated with cumulative exposure to SUA and its accumulation time course. Early SUA accumulation resulted in a greater risk compared with later accumulation, underscoring the importance of early control of SUA to an optimal level.

ABSTRACT

Transplantation is the most effective treatment for end-stage chronic kidney disease, as this procedure prolongs and improves the patient’s quality of life. One of the key problems is the risk of graft rejection. The purpose of this research was to identify and analyse prognostic factors that will prevent rejection. In particular, the prognostic factors grouped by methods of synthesis, generalisation and statistical processing with calculation and graphical representation of hazard ratio and correlation coefficient were grouped, namely: age of donor and recipient, time of cold kidney ischaemia, duration of preoperative dialysis, body mass index, presence of concomitant diseases (diabetes mellitus, hypertension), primary causes causing transplantation. Several molecular genetic and biochemical prognostic markers (transcription factors, immunocompetent cell signalling and receptors, cytostatin C, creatinine, citrate, lactate, etc.) are annotated. It has been demonstrated that creatinine reduction rate determines the risk of rejection, displaying the dynamics of cystatin C and creatinine changes in the postoperative period. Young recipients who underwent prolonged preoperative dialysis were identified as having the highest risk of rejection. Diabetes and hypertension bear a non-critical but commensurately equal risk of rejection. The survival rate of the graft is better when transplanted from a living donor than from a deceased donor. A correlation between cold ischaemia time, body mass index and the probability of graft failure has been proven, namely, the greater the donor and recipient body mass index and the longer the cold ischaemia time, the lower the chance of successful long-term organ acclimation. The data obtained can be used as prognostic factors for graft accommodation at different intervals after surgery.

ABSTRACT

The “Kickstart to Recovery” program is a collaboration between Irish mental health occupational therapists and the Football Association of Ireland. This pilot study aimed to investigate whether participants experienced changes in quality of life, recovery, social gains, and the meaning of football following participation in the program. A quantitative pre-post study design was employed, with 27 participants completing a questionnaire consisting of outcome measures aimed to measure the above changes. Findings revealed statistically significant improvements in the Short Form 36 Health Survey Questionnaire (SF-36) “Energy/Fatigue” domain for the total sample and the Recovery Assessment Survey-Domains and Scales (RAS-DS) “Mastering My Illness” domain for first-time program participants. Statistically significant results were found for domains of “Social Functioning” and “Emotional Wellbeing” in groups incorporating additional social elements. The Engagement in Meaningful Activities Survey (EMAS) showed no change for the personal meaning participants attributed to football; however, high pre-test scores were noted. The “Kickstart to Recovery” program is attributed as a possible factor contributing to these results.

ABSTRACT

Single-molecule experiments allow understanding of the diversity, stochasticity, and heterogeneity of molecular behaviors and properties hidden by conventional ensemble-averaged measurements. They hence have great importance and significant impacts in a wide range of fields. Despite significant advances in single-molecule experiments at ultralow concentrations, the capture of single molecules in solution at normal concentrations within natural biomolecular processes remains a formidable challenge. Here, a high-density, well-defined nanofluidic aptamer nanoarray (NANa) formed via site-specific self-assembly of well-designed aptamer molecules in nanochannels with nano-in-nano gold nanopatterns is presented. The nanofluidic aptamer nanoarray exhibits a high capability to specifically capture target proteins (e.g., platelet-derived growth factor BB; PDGF-BB) to form uniform protein nanoarrays under optimized nanofluidic conditions. Owing to these fundamental features, the nanofluidic aptamer nanoarray enables the stochastic capture of single PDGF-BB molecules at a normal concentration from a sample with a ultrasmall volume equivalent to a single cell by following Poisson statistics, forming a readily addressable single-protein nanoarray. This approach offers a methodology and device to surpass both the concentration and volume limits of single-protein capture in most conventional methodologies of single-molecule experiments, thus opening an avenue to explore the behavior of individual biomolecules in a manner close to their natural forms, which remains largely unexplored to date.

ABSTRACT

OBJECTIVE: This study aimed to clarify the relationship between recurrence and the extent of resection in surgery for intramedullary spinal hemangioblastoma (sHB) and its impact on von Hippel-Lindau (vHL) disease.

METHODS: Data on sHB cases followed up for at least 6 months after surgery were extracted from a nationwide registry of 1,033 consecutive spinal intramedullary tumors surgically treated between 2009 and 2020, and were retrospectively categorized into a sporadic or vHL group. The diagnosis of vHL disease was made at each institution based on clinical findings.

RESULTS: A total of 168 patients (sporadic group, 101; vHL group, 67) were included in the study. Compared with the sporadic group, the vHL group had a younger onset (45.4±16.8 v.s. 39.6±14.1 years, p=0.02), more preoperative motor (47.5 v.s. 68.7%, p<0.01) and gait (37.6 v.s. 61.2%, p<0.01) impairments, and more patients with worsening neurological symptoms at discharge (p=0.02). The gross total resection (GTR) rates and the recurrence rates were not statistically different between the sporadic and the vHL groups. GTR significantly improved recurrence-free survival compared to non-GTR in all patient analysis (p<0.01) but this trend was not observed in the sporadic group. Physical functional improvement from discharge to 6 months after surgery was observed in the sporadic group (p<0.01) but not in the vHL group.

CONCLUSION: A high GTR rate may sufficiently decrease susceptibility to recurrence, especially in patients with sHB with vHL. In sporadic sHB, postoperative functional improvement can be expected, and the long-term functional prognosis is favorable.

ABSTRACT

BACKGROUND: Exercise-based interventions prevent or delay symptoms and complications of type 2 diabetes (T2D) and are highly recommended for T2D patients; though with very low participation rates. Τelerehabilitation (TR) could act as an alternative to overcome the barriers preventing the promotion of T2D patients’ well-being.

AIM: Determine the effects of a six-week TR program on glycemic control, functional capacity, muscle strength, PA, quality of life and body composition in patients with T2D.

DESIGN: A multicenter randomized, single-blind, parallel-group clinical study.

SETTING: Clinical trial.

POPULATION: Patients with T2D.

METHODS: Thirty T2D patients (75% male, 60.1±10.9 years) were randomly allocated to an intervention group (IG) and a control group (CG) with no exercise intervention. IG enrolled in a supervised, individualized exercise program (combination of aerobic and resistance exercises), 3 times/week for 6 weeks at home via a TR platform. Glycated hemoglobin (HbA1c), six-minute walk test (6MWT), muscle strength (Hand Grip Strength Test [HGS], 30-Second Chair Stand test [30CST] physical activity [IPAQ-SF]), quality of life (SF-36) and anthropometric variables were assessed.

RESULTS: Two-way repeated-ANOVA showed a statistically significant interaction between group, time and test differences (6MWT, muscle strength) (V=0.33, F [2.17]=4.14, P=0.03, partial η²=0.22). Paired samples t-test showed a statistically significant improvement in HbA1c (Z=-2.7), 6MWT (Μean ∆=-36.9±27.2 m, t=-4.5), muscle strength (Μean ∆=-1.5±1.4 kg, t=-2.22). Similarly, SF-36 (mental health [Μean ∆=-13.3±21.3%], general health [Μean ∆<inf>=</inf>-11.4±16.90%]) were statistically improved only in IG.

CONCLUSIONS: The findings of this study indicate that a 6-week supervised home-based TR exercise program induced significant benefits in patients with T2D, thus enabling telehealth implementation in rehabilitation practice as an alternative approach.

CLINICAL REHABILITATION IMPACT: Home-based exercise via the TR platform is a feasible and effective alternative approach that can help patients with T2D eliminate barriers and increase overall rehabilitation utilization.
