ABSTRACT

BACKGROUND: Brown seaweed is promising for the treatment of type 2 diabetes mellitus (T2DM). Its bioactive constituents can positively affect plasma glucose homeostasis in healthy humans. We investigated the effect of the brown seaweeds Sargassum (S.) fusiforme and Fucus (F.) vesiculosus in their natural form on glucose regulation in patients with T2DM. METHODS: We conducted a randomized, double-blind, placebo-controlled pilot trial. Thirty-six participants with T2DM received, on a daily basis, either 5 g of dried S. fusiforme, 5 g of dried F. vesiculosus, or 0.5 g of dried Porphyra (control) for 5 weeks, alongside regular treatment. The primary outcome was the between-group difference in the change in weekly average blood glucose levels (continuous glucose monitoring). The secondary outcomes were the changes in anthropometrics, plasma lipid levels, and dietary intake. The data were analyzed using a linear mixed-effects model. RESULTS: The change in weekly average glucose levels was 8.2 ± 2.1 to 9.0 ± 0.7 mmol/L (p = 0.2) in the S. fusiforme group (n = 12) and 10.1 ± 3.3 to 9.2 ± 0.7 mmol/L (p = 0.9) in the F. vesiculosus group (n = 10). The between-group difference was non-significant. Similarly, no between-group differences were observed for the changes in the secondary outcomes. DISCUSSION: A daily intake of 5 g of fresh, dried S. fusiforme or F. vesiculosus alongside regular treatment had no differential effect on weekly average blood glucose levels in T2DM.

ABSTRACT

Anxious individuals consistently fail in controlling emotional behavior, leading to excessive avoidance, a trait that prevents learning through exposure. Although the origin of this failure is unclear, one candidate system involves control of emotional actions, coordinated through lateral frontopolar cortex (FPl) via amygdala and sensorimotor connections. Using structural, functional, and neurochemical evidence, we show how FPl-based emotional action control fails in highly-anxious individuals. Their FPl is overexcitable, as indexed by GABA/glutamate ratio at rest, and receives stronger amygdalofugal projections than non-anxious male participants. Yet, high-anxious individuals fail to recruit FPl during emotional action control, relying instead on dorsolateral and medial prefrontal areas. This functional anatomical shift is proportional to FPl excitability and amygdalofugal projections strength. The findings characterize circuit-level vulnerabilities in anxious individuals, showing that even mild emotional challenges can saturate FPl neural range, leading to a neural bottleneck in the control of emotional action tendencies.

ABSTRACT

PURPOSE: Evidence to date shows that distal radius fracture displacement measured on radiographs does not correlate with patient-reported outcomes. Quantitative 3-dimensional computed tomography (CT) (Q3DCT) potentially captures fracture displacement more accurately. We aimed to assess the independent association between radiographic, CT, and Q3DCT measures of residual displacement and change in disability, quality of life, range of motion (ROM), and grip strength 12 weeks and 1 year after volar plating of intra-articular distal radius fractures. METHODS: We performed a secondary analysis of data from a prospective multicenter trial. Seventy-one patients underwent volar plating of their AO Foundation/Orthopaedic Trauma Association type B or C distal radius fracture and were available at 12 weeks; 67 (94%) were available at 1 year. We recorded demographics, postoperative periapical radiographs (radial height, ulnarward inclination, ulnar variance, gap, and step off), lateral radiographs (palmar tilt, scapholunate angle, teardrop angle, and anteroposterior distance), postoperative CT scans (gap [coronal, sagittal and axial]) and step off [sagittal and coronal]), and in 3-dimensional models (number of articular fragments, mean fragment articular surface area, 3-dimensional fragment displacement, and gap surface area). Radiographs and CT scans were obtained within 10 working days after fracture fixation. Outcome measures were change in Patient-Rated Wrist Evaluation (PRWE) scores, EuroQol Group 5-Dimension questionnaire (EQ5D) results, grip strength, and composite wrist ROM at 12 weeks and 1 year compared to preinjury level. RESULTS: At 1 year, greater recovery in PRWE scores was independently associated with older age. Greater recovery in composite ROM at 1 year was associated with injury to the dominant side and less step-off on posteroanterior radiographs. CONCLUSIONS: Less posteroanterior step-off was associated with a small improvement in composite wrist ROM at 1 year. This should be considered when counseling patients on the risks and benefits of surgical treatment when radiographic and CT measures of displacement fall within the range found in this study, and in older, low-demand patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

ABSTRACT

INTRODUCTION: Nutrition plays an essential role in the recovery of critical illness. In the post-Intensive Care Unit (ICU) period, patients typically return to oral nutrition gradually. However, studies quantifying nutritional intake in the post-ICU hospitalization period are scarce and formal guidelines are lacking. This study aims to describe energy and protein intake in detail over the entire post-ICU hospitalization period and explore associations between protein intake and clinical outcomes. METHODS: A prospective observational single-center cohort study was conducted amongst post-ICU patients in general wards after a minimum ICU-stay of 72 h and who received (par)enteral feeding for ≥24 h in the ICU. Oral intake was assessed daily using food order lines and digital photography of meal leftovers. Other data, including amounts of (par)enteral nutrition, were collected from electronic medical records. The primary outcome was to identify energy and protein intake, and reached targets, in the post-ICU period. In addition, length of hospital stay after ICU discharge, readmission and mortality rates were compared between patients meeting protein targets or not. RESULTS: In total, 48 patients were included. Complete nutritional data of 34 patients were analyzed in the current study, adding up to a total number of 484 observational days, 1681 photos and 6634 food order lines. Inter-rater agreement was excellent (ICC 0.878). Overall mean energy and protein adequacy for all nutritional groups was 82.3% (SD 18.3) and 83.1% (SD 19.8). Only 51.2% of the study participants (n = 21) reached overall >90% of prescribed protein targets during their entire post-ICU ward stay. The lowest intake was seen in the patient group with exclusively oral intake (median protein adequacy 75.5%), whereas patients with (supplemental) enteral nutrition (EN) all met >90% of their protein targets. Prescribed targets were below recommendations, and prescribed calories and proteins were neither ordered nor consumed. Discontinuation of EN resulted in immediate marked drops in energy (44.1%) and protein intake (50.7%). Subsequently, patients needed up to six days to reach protein targets again. No differences in clinical outcomes were observed. CONCLUSION: Most patients did not meet energy and protein targets in the post-ICU hospitalization period. Nutrition performance was highly dependent on the route of nutrition and was lowest among patients with oral intake only (despite of food fortification strategies and/or oral nutritional supplements). The best intake was observed in patients receiving (supplemental) EN. However, cessation of EN posed an immediate nutritional risk. No differences in clinical outcomes were found in this study. Our findings stress the need for follow-up studies to close the gap with individualized nutritional support in the post-ICU period to reach protein and energy targets.

ABSTRACT

Acutely challenging or threatening situations frequently require approach-avoidance decisions. Acute threat triggers fast autonomic changes that prepare the body to freeze, fight or flee. However, such autonomic changes may also influence subsequent instrumental approach-avoidance decisions. Since defensive bodily states are often not considered in value-based decision-making models, it remains unclear how they influence the decision-making process. Here, we aim to bridge this gap by discussing the existing literature on the potential role of threat-induced bodily states on decision making and provide a new neurocomputational framework explaining how these effects can facilitate or bias approach-avoid decisions under threat. Theoretical accounts have stated that threat-induced parasympathetic activity is involved in information gathering and decision making. Parasympathetic dominance over sympathetic activity is particularly seen during threat-anticipatory freezing, an evolutionarily conserved response to threat demonstrated across species and characterized by immobility and bradycardia. Although this state of freezing has been linked to altered information processing and action preparation, a full theoretical treatment of the interactions with value-based decision making has not yet been achieved. Our neural framework, which we term the Threat State/Value Integration (TSI) Model, will illustrate how threat-induced bodily states may impact valuation of competing incentives at three stages of the decision-making process, namely at threat evaluation, integration of rewards and threats, and action initiation. Additionally, because altered parasympathetic activity and decision biases have been shown in anxious populations, we will end with discussing how biases in this system can lead to characteristic patterns of avoidance seen in anxiety-related disorders, motivating future pre-clinical and clinical research.

ABSTRACT

This study aimed to determine the association of teardrop angle and anteroposterior distance with anterior lunate facet displacement and articular congruity before and after anterior plating of distal radial fractures. We included 36 patients with complete intra-articular distal radial fractures with separate anterior lunate facet fragments. On radiographs we determined the teardrop angle and anteroposterior distance. On digital three-dimensional models we measured proximal-distal, anteroposterior and ulnoradial anterior lunate facet displacement, and we outlined the gap surface area. Preoperatively, teardrop angle was highly associated with the extent of anterior lunate facet displacement. Increased anteroposterior distance was mainly associated with articular incongruity after anterior plate fixation. This information may reduce the need of preoperative computed tomography scans in fractures with a normal tear drop angle. This is particularly useful in low-resource settings.

ABSTRACT

BACKGROUND: Calcaneal fractures are uncommon and have a substantial impact on hindfoot function and quality of life. Several surgical treatment options are available; both in surgical approach and type of operation. The aim of this study was to compare functional outcome and quality of life following ORIF and primary arthrodesis. Furthermore, predictors of worse functional outcome were explored. METHODS: A retrospective cross-sectional cohort study was performed in patients with surgical fixation of a calcaneal fracture with a minimum follow-up of 18 months. Patients received ORIF through the 1) Extended Lateral Approach (ELA), 2) Sinus Tarsi Approach (STA) or 3) primary arthrodesis via STA. Participants were presented a questionnaire containing demographics, the AOFAS hindfoot scale, Foot Function Index, SF-36, EQ-5D and patient satisfaction. RESULTS: In total 95 patients participated in this study. The three groups were comparable regarding patient characteristics. A median score of 74.5 points on the AOFAS hindfoot scale and 11.9 on the FFI was found for the entire group. There were no statistically significant differences between patients with ORIF of primary arthrodesis. Patients scored a median of 49.0 on the Physical Component Scale of the SF-36 and 55.4 on the Mental Component Scale. On the EQ-5D patients scored a median of 0.8 points. Again no statistically significant differences were observed between the three subgroups. Socio-economic status was the only statistically significant predictor of worse functional outcome (ß: 4.06, 95% CI: 0.50-7.62) after multivariable analysis. INTERPRETATION: Good midterm outcomes following in terms of functional outcome and in quality of life are observed. We observed no statistical significant difference in functional outcome between patients with ORIF and patients with primary arthrodesis. The only predictor of worse functional outcome is a lower socio-economic status.

ABSTRACT

BACKGROUND: The main reconstruction techniques for proximal humerus tumors include osteoarticular allografts (OAs), endoprostheses (EPs), or allograft prosthetic composites (APCs). A common complication is infection, and constructs involving the use of allografts are believed to be at a higher risk of infection. Literature comparing infection rates between different modalities of reconstruction is scarce and underpowered. The study purposes were (1) to determine and compare the prevalence of infection in patients who underwent reconstruction of the proximal humerus including OAs, EPs, and APCs; (2) to identify preoperative, perioperative, and postoperative predictors of infection that might be modifiable; and (3) to present our protocol of treatment in patients with superficial and deep infections. METHODS: We reviewed 150 patients of all ages with proximal humerus tumors treated by an OA, EP, or APC at 2 tertiary institutions. The prevalence of infection for each modality was calculated and compared between groups. We identified potential predictors of infection with stepwise backward multivariate Cox regression analysis. RESULTS: An infection developed in 19 patients (12%): 5 of 45 (11%) in the OA group, 12 of 85 (14%) in the EP group, and 2 of 20 (10%) in the APC group (P = .740). A lower preoperative hemoglobin blood level and low preoperative albumin blood level were independently associated with infection. CONCLUSIONS: We found similar infection rates compared with previously reported series. However, we did not identify a higher infection prevalence in constructs using allografts. Patients with a lower preoperative hemoglobin or albumin level are at higher risk of infection and should undergo optimization before surgery.

ABSTRACT

Background Perilunate injuries are complex and uncommon injuries that are typically the result of a high-energy injury and are nearly always treated operatively. Little is known about factors associated with unplanned reoperations after surgery for perilunate injuries. Purpose To assess the rate and types of unplanned reoperation after operative treatment of a perilunate dislocation. Patients and Methods We reviewed 115 patients of all ages with unplanned reoperations after operative treatment of perilunate injuries at five hospitals. Planned removal of implants were not considered as unplanned reoperations. Results Sixteen patients had an unplanned reoperation, including four for compartment syndrome (three hand, one forearm); three for deep infection; three for malalignment or an errant screw; two for early salvage procedures; and four for other reasons. We considered seven unplanned reoperations necessary (forearm compartment syndrome, infection, loss of alignment, errant screw) and nine debatable or unnecessary (hand compartment syndrome, early salvage procedures, suspected malunion, etc.). Patients who had an unplanned reoperation were younger (median age 24 versus 34 years; p = 0.0034); had earlier surgery (median days to surgery 0 versus 3; p = 0.0068); and were more likely injured in a motor vehicle collision (50% versus 17%; p = 0.0070). Accounting for interaction among the variables using multivariable analysis, the factors independently associated with unplanned reoperation were young age (odds ratio 0.92) and motor vehicle collision accidents (odds ratio 4.1). Conclusion We conclude that higher-energy injuries may be at greater risk for unplanned reoperation, but more than half of the unplanned reoperations were for debatable indications.
