Effect of exercise training after bariatric surgery: A 5-year follow-up study of a randomized controlled trial

Background and objectives We previously showed in a 6-month randomized controlled trial that resistance training and protein supplementation after bariatric surgery (Roux-en-Y gastric bypass, RYGB) improved muscle strength without significant effect on weight loss and body composition changes. We performed a 5-year follow-up study in these subjects with the aim 1) to assess the long-term effect of this exercise training intervention and 2) to analyze associations between habitual physical activity (PA) and weight regain at 5 years. Methods Fifty-four out of 76 initial participants (follow-up rate of 71%) completed the 5-year follow-up examination (controls, n = 17; protein supplementation, n = 22; protein supplementation and resistance training, n = 15). We measured body weight and composition (DXA), lower-limb strength (leg-press one-repetition maximum) and habitual PA (Actigraph accelerometers and self-report). Weight regain at 5 years was considered low when <10% of 12-month weight loss. Results Mean (SD) time elapse since RYGB was 5.7 (0.9) y. At 5 years, weight loss was 32.8 (10.1) kg, with a mean weight regain of 5.4 (SD 5.9) kg compared with the 12-month assessment. Moderate-to-vigorous PA (MVPA) assessed by accelerometry did not change significantly compared with pre-surgery values (+5.2 [SD 21.7] min/d, P = 0.059), and only 4 (8.2%) patients reported participation in resistance training. Muscle strength decreased over time (overall mean [SD]: -49.9 [53.5] kg, respectively, P<0.001), with no statistically significant difference between exercise training intervention groups. An interquartile increase in MVPA levels was positively associated with lower weight regain (OR [95% CI]: 3.27 [1.41;9.86]). Conclusions Early postoperative participation in a resistance training protocol after bariatric surgery was not associated with improved muscle strength after 5 years of follow-up; however, increasing physical activity of at least moderate intensity may promote weight maintenance after surgery. PA may therefore play an important role in the long-term management of patients with obesity after undergoing bariatric procedure.
A pilot retrospective study of comprehensive nursing care on psychological disorder in colorectal cancer undergoing chemotherapy

Background: This pilot study retrospectively evaluated the effects of comprehensive nursing care (CNC) on psychological disorders in patients with colorectal cancer (CC) undergoing chemotherapy. Methods: This study analyzed 70 eligible patients’ case records of CC undergoing chemotherapy. These records were allocated to a treatment group (n = 35) or a control group (n = 35). All 70 patients in both groups received routine nursing care. In addition, 35 patients in the treatment group also received CNC. The primary outcomes were anxiety, as measured by Self-rating Anxiety Scale, and depression, as assessed by Self-rating Depression Scale. The secondary outcomes were quality of life, as measured by The 36-Item Short Form Health Survey, and adverse events. All outcome data were analyzed before and 3-month after treatment. Results: At 3-month after treatment, the patients in the treatment group had better outcomes in the Self-rating Anxiety Scale (P<0.01), Self-rating Depression Scale (P<0.01), and The 36-Item Short Form Health Survey (social function, P = .04; emotional role, P = 0.03) than those in the control group. With regard to safety, no treatment-related adverse events were recorded in either group. Conclusion: The findings of this pilot retrospective study showed promising effects of CNC on psychological disorders and quality of life in patients with CC undergoing chemotherapy. However, more high-quality clinical trials are required to confirm these findings.
Development of a strategy for assessing blood-brain barrier disruption using serum S100 calcium-binding protein B and neuron-specific enolase in early stage of neuroemergencies: A preliminary study

Background: Rapid disease progression in neuroemergencies is associated with blood-brain barrier (BBB) disruption. We investigated a less invasive strategy for assessing BBB status by evaluating S100 calcium-binding protein B (S100B) and neuron-specific enolase (NSE) at early stages of the hypoxic-ischemic brain injury (HIBI) cascade. Methods: This retrospective study used prospectively collected data from patients with out-of-hospital cardiac arrest (August 2019–July 2021). Albumin specimens obtained from serum and cerebrospinal fluid via arterial catheter and lumbar puncture were used to measure the albumin quotient (Qa), which is widely accepted as the gold standard method for detecting BBB disruption. Serum S100B and NSE levels were measured simultaneously following the return of spontaneous circulation. We conducted linear regression to evaluate the relationship between S100B and Qa and the predictive performance of S100B for abnormal Qa. The primary study outcome was abnormal Qa (>0.007). Results: Forty-one patients were enrolled; 30 showed an abnormal Qa suggestive of BBB disruption. S100B levels were significantly higher than in those with a normal Qa (0.244 μg/L [interquartile range [IQR], 0.146–0.823 vs 0.754 μg/L [IQR, 0.317–2.228], P = .03). We report a positive correlation between serum S100B and Qa (R2 = 0.110; P = .04). The area under the receiver operating characteristics curve (AUROC) evaluating the predictive performance of S100B with respect to abnormal Qa was 0.718 (95% confidence interval, 0.556–0.847). The cutoff value for S100B (with respect to BBB disruption) in the total cohort was 0.283 μg/L (sensitivity, 80.0%; specificity, 72.7%). Subgroup analyses in patients with serum neuron-specific enolase (NSE) levels of <40.8 ng/mL (excluding those with established neuronal cell injury) showed an improved correlation coefficient (R2 = 0.382; P < .01) and predictive performance (AUROC, 0.836 [95% confidence interval, 0.629–0.954]) compared with the total cohort. Conclusions: Serum S100B obtained at an early stage of the HIBI cascade is associated with abnormal Qa, suggesting BBB disruption. The predictive performance of S100B and the correlation between serum S100B and Qa can be improved using a complementary strategy (i.e., evaluations of S100B and NSE levels) that combines considerations of cell damage in astrocytes and neurons.
DETERMINING OF THE EQUIVALENT AND OPTIMUM DIAMETERS OF CONE-CYLINDER TIP WITH SOIL BROACHING SPURS

Purpose. Building of new railway tracks and facilities, repair and replacement of existent underground utilities and communications is related to the receipt of horizontal cavities in soil by trenchless method. A static soil broaching with a working body with cone tip is the most widespread method in practice of forming a pilot hole at the trenchless laying of distributive communications. However, in the process of implementation of project calculations, receipt of pilot hole and subsequent expansion to the necessary sizes, there is a question of workings effort calculation methods. Existent methods are based on empiric dependences and experimental coefficients which diminish exactness of calculations and increase the cost of works. Methodology. The work proposes the dependence for determination of equivalent diameter of cone tip depending on the hole diameter and theoretical method for calculation of optimum parameters of soil broaching head using the well-known parameters: type of soil and its humidity, that determined by the State Construction Regulations (DBN). Findings. The results of the theoretical studies can be used to increase the efficiency of the working equipment for soil broaching by static method during trenchless laying of underground utilities and communications. Originality. The authors establish the dependence of the equivalent diameter of the cone base on the diameter of the cylindrical part of the broaching head, which allows for removal of the frictional force from the static broaching on the lateral cylindrical surface of the tip. Practical value. The obtained theoretical calculations for determining the optimal diameters of the cone tip with soil broaching spurs made it possible to establish that if the diameter of the cone is greater than the maximum diameter of the hole ( soil cavity ), then the frontal resistance of the cone - cylinder tip increases more intensively than the resistance of the cylindrical part of the tip . The maximum reduction in the broaching force takes place for a soil cavity whose diameter is 2 times smaller than the maximum limit diameter. When conducting the calculations regarding the choice of the size of working bodies for soil broaching, the source data include the type of soil, and its characteristics by DBN, as well as the moisture content of the soil determined by traditional methods.
Complexities in Modeling Organic Aerosol Light Absorption

Aerosol particles dynamically evolve in the atmosphere by physicochemical interactions with sunlight, trace chemical species, and water. Current modeling approaches fix properties such as aerosol refractive index, introducing spatial and temporal errors in the radiative impacts. Further progress requires a process-level description of the refractive indices as the particles age and experience physicochemical transformations. We present two multivariate modeling approaches of light absorption by brown carbon (BrC). The initial approach was to extend the modeling framework of the refractive index at 589 nm (nD), but that result was insufficient. We developed a second multivariate model using aromatic rings and functional groups to predict the imaginary part of the complex refractive index. This second model agreed better with measured spectral absorption peaks, showing promise for a simplified treatment of BrC optics. In addition to absorption, organic functionalities also alter the water affinity of the molecules, leading to a hygroscopic uptake and increased light absorption, which we show through measurements and modeling.
The psychological impact on perioperative healthcare workers during Victoria’s second COVID-19 wave: A prospective longitudinal thematic analysis

The COVID-19 pandemic has had a profound psychological impact on our frontline healthcare workers. Throughout the entire second COVID-19 wave at one major tertiary hospital in Melbourne Australia, longitudinal qualitative data between perioperative staff members, and analyses of intrapersonal changes were reported. Inductive analysis of three open-ended questions generated four major themes: Organisational Response to the Pandemic, Psychological Impact, Changes in Feelings of Support Over Time and Suggestions for Changes. Understanding the challenges, perception and suggestions from this longitudinal study allows us to provide a range of support services and interventions to minimise the long-term negative psychological impact and be better prepared should another similar situation arises again.
Effects of Drop Jump Training from Different Heights and Weight Training on Vertical Jump and Maximum Strength Performance in Female Volleyball Players

Abstract Sotiropoulos, K, Smilios, I, Barzouka, K, Christou, M, Bogdanis, G, Douda, H, and Tokmakidis, SP. Effects of drop jump training from different heights and weight training on vertical jump, maximum strength and change of direction performance in female volleyball players. J Strength Cond Res 37(2): 423–431, 2023—This study compared the effects of drop jump (DJ) training from different drop heights and weight training on vertical jump and maximum strength performance. Fifty-five female volleyball players (age: 23.8 ± 4.3 years) were randomly and equally allocated to a control group (volleyball training, CG); a volleyball and weight training group (WG); and 3 volleyball, weight, and drop jump training groups. One group performed DJ training from the optimal drop height, i.e., the height that elicited the highest ratio of jump height to contact time (OG), a second group from a drop height 25% higher than the optimal (HG), and a third group from a drop height 25% lower than the optimal (LG). Drop jump and weight training were performed 1–2 times per week, for 8 weeks for a total of 13 sessions. After training, vertical jump performance improved by 3.6–17.4% (p < 0.05; effect size [ES]: 1.03–1.23) in the OG and the HG compared with the LG, WG, and CG (p < 0.05; ES: 0.03–0.58). Drop jump height from drop heights 20–70 cm increased by 10.0–20.2% (p < 0.05; ES: 0.59–1.13) for the OG and the HG, while reactive strength index increased (p < 0.05; ES: 0.74–1.40) by 19.6–33.9% only in the HG compared with the CG. Half-squat maximum strength was increased in all experimental groups by 17.4–19% compared with the CG (p < 0.05) with no differences (p > 0.05) observed among them. The use of the optimal height or a moderately higher drop height by 25% for DJ training, combined with weight training, seems to be the most beneficial option to improve vertical jump and reactive strength index in female volleyball players.
HDL-C levels added to the MELD score improves 30-day mortality prediction in Asian patients with cirrhosis

Objectives Lower high-density lipoprotein cholesterol (HDL-C) levels have been observed in chronic liver disease patients. The aim of this study was to develop a model that incorporates HDL-C levels and the Model for End-stage Liver Disease (MELD) score to predict 30-day mortality in Asian cirrhosis patients. Methods Cirrhosis patients were recruited from two hospitals in this retrospective observational study. Propensity score matching was used. The model’s performance was evaluated, including its ability to predict 30-day mortality, accuracy, and clinical utility. Net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were calculated. Results The HDL-C + MELD model showed good ability to predict 30-day mortality (area under the curve, 0.784; sensitivity, 0.797; specificity, 0.632), which was better than that of the MELD score alone. It also showed good calibration and a net benefit for all patients, which was better than that of the MELD score, except at the threshold probability. NRI and IDI results confirmed that adding HDL-C levels to the MELD score improved the model’s performance in predicting 30-day mortality. Conclusion We added HDL-C levels to the MELD score to predict 30-day mortality in Asian patients with cirrhosis. The HDLC + MELD model shows good ability to predict 30-day mortality and clinical utility.
A New Polymer Donor Enables Binary All‐Polymer Organic Photovoltaic Cells with 18% Efficiency and Excellent Mechanical Robustness

The development of polymerized small‐molecule acceptors has boosted the power conversion efficiencies (PCEs) of all‐polymer organic photovoltaic (OPV) cells to 17%. However, the polymer donors suitable for all‐polymer OPV cells are still lacking, restricting the further improvement of their PCEs. Herein, a new polymer donor named PQM‐Cl is designed and its photovoltaic performance is explored. The negative electrostatic potential and low average local ionization energy distribution of the PQM‐Cl surface enable efficient charge generation and transfer process. When blending with a well‐used polymer acceptor, PY‐IT, the PQM‐Cl‐based devices deliver an impressive PCE of 18.0% with a superior fill factor of 80.7%, both of which are the highest values for all‐polymer OPV cells. The relevant measurements demonstrate that PQM‐Cl‐based films possess excellent mechanical and flexible properties. As such, PQM‐Cl‐based flexible photovoltaic cells are fabricated and an excellent PCE of 16.5% with high mechanical stability is displayed. These results demonstrate that PQM‐Cl is a potential candidate for all‐polymer OPV cells and provide insights into the design of polymer donors for high‐efficient all‐polymer OPV cells.
Surgeon-Placed Erector Spinae Plane Catheters for Multilevel Lumbar Spine Fusion: Technique and Outcomes Compared With Single-Shot Blocks

Background Postoperative pain management of multilevel lumbar fusion remains challenging. There are few reports of opioid-sparing regional analgesia for spine surgery. We present a novel method for surgeon-placed erector spinae plane (ESP) catheters for multilevel lumbar spine fusion and compare pain- and opioid-related outcomes in a matched cohort who received anesthesiologist-placed ESP blocks. Methods A retrospective matched pilot study of 18 patients: 6 received intraoperative, bilateral ESP catheters. Tunneled catheters were placed under the intact ESP at the proximal end of the incision. Continuous infusions of ropivacaine (0.2%) were started in the postanesthesia care unit (PACU) after emergence from anesthesia and maintained for 48 hours. Catheter patients were matched 1:2 with 12 patients who received preincision single-shot ESP blocks administered by an anesthesiologist, according to age, gender, American Society of Anesthesiologists class, body mass index, and number of spinal levels fused. All patients were provided opioid intravenous patient-controlled analgesia (IV-PCA). Numeric rating scale pain scores (NRS, 0–10), length of stay (LOS), opioid consumption (oral morphine equivalents, mg), opioid side effects, and complications (motor weakness, local anesthetic toxicity, infection, technical issues, and failure), were compared in the PACU and on the nursing floor. Results Only 1/6 patients with ESP catheter used opioid IV-PCA, compared with 11/12 who received ESP blocks. There were no differences in total opioid consumption (catheters: 135 ± 141 mg; blocks: 183 ± 112 mg; P = 0.448) or median (interquartile range) LOS (catheters: 73 [50,107] hours; blocks: 90 [72,116] hours, P = 0.708). NRS pain was significantly higher in the PACU after ESP catheters (5.9 ± 1.7) vs ESP blocks (3.3 ± 2.4; P = 0.036), but no differences were found at later timepoints (5.0 ± 1.6 vs 4.3 ± 1.1, respectively; P = 0.383). No catheter-related complications were found. Conclusion Surgeon-placed ESP catheters represent a simple technique to provide regional analgesia, particularly in centers lacking regional anesthesiology services. Risks, benefits, and efficacy compared to other techniques require prospective study. Level of Evidence 3.
Explainable Drug Repurposing Approach From Biased Random Walks

Drug repurposing is a highly active research area, aiming at finding novel uses for drugs that have been previously developed for other therapeutic purposes. Despite the flourishing of methodologies, success is still partial, and different approaches offer, each, peculiar advantages. In this composite landscape, we present a novel methodology focusing on an efficient mathematical procedure based on gene similarity scores and biased random walks which rely on robust drug-gene-disease association data sets. The recommendation mechanism is further unveiled by means of the Markov chain underlying the random walk process, hence providing explainability about how findings are suggested. Performances evaluation and the analysis of a case study on rheumatoid arthritis show that our approach is accurate in providing useful recommendations and is computationally efficient, compared to the state of the art of drug repurposing approaches.
A phylogenetic study to assess the link between biome specialization and diversification in swallowtail butterflies

The resource‐use hypothesis, proposed by E.S. Vrba, states that habitat fragmentation caused by climatic oscillations would affect particularly biome specialists (species inhabiting only one biome), which might show higher speciation and extinction rates than biome generalists. If true, lineages would accumulate biome‐specialist species. This effect would be particularly exacerbated for biomes located at the periphery of the global climatic conditions, namely, biomes that have high/low precipitation and high/low temperature such as rainforest (warm‐humid), desert (warm‐dry), steppe (cold‐dry) and tundra (cold‐humid). Here, we test these hypotheses in swallowtail butterflies, a clade with more than 570 species, covering all the continents but Antarctica, and all climatic conditions. Swallowtail butterflies are among the most studied insects, and they are a model group for evolutionary biology and ecology studies. Continental macroecological rules are normally tested using vertebrates, this means that there are fewer examples exploring terrestrial invertebrate patterns at global scale. Here, we compiled a large Geographic Information System database on swallowtail butterflies' distribution maps and used the most complete time‐calibrated phylogeny to quantify diversification rates (DRs). In this paper, we aim to answer the following questions: (1) Are there more biome‐specialist swallowtail butterflies than biome generalists? (2) Is DR related to biome specialization? (3) If so, do swallowtail butterflies inhabiting extreme biomes show higher DRs? (4) What is the effect of species distribution area? Our results showed that swallowtail family presents a great number of biome specialists which showed substantially higher DRs compared to generalists. We also found that biome specialists are unevenly distributed across biomes. Overall, our results are consistent with the resource‐use hypothesis, species climatic niche and biome fragmentation as key factors promoting isolation.
Efficacy and Safety of Dupilumab Versus Omalizumab in Chronic Rhinosinusitis With Nasal Polyps and Asthma: EVEREST Trial Design

Background Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma are chronic type 2 inflammatory diseases that are frequently associated with each other. Dupilumab inhibits the dual signaling pathways of interleukin (IL)-4 and IL-13, which are key and central drivers of type 2 inflammation in CRSwNP. Omalizumab blocks the action of immunoglobulin E. Head-to-head studies are required to investigate the comparative efficacy and safety of these interventions. EVEREST (EValuating trEatment RESponses of dupilumab vs omalizumab in Type 2 patients) trial is designed to evaluate whether the efficacy of dupilumab is superior to omalizumab in treating patients with CRSwNP and comorbid asthma (ClinicalTrials.gov Identifiers: NCT04998604). Objective Here, we describe the EVEREST study design to compare the efficacy and safety of dupilumab compared to omalizumab over 24 weeks of treatment in patients with severe CRSwNP and comorbid asthma. Methods EVEREST is a global, phase 4 multicenter, randomized (1:1), double-blind, active-controlled trial. Approximately 422 adult patients with severe CRSwNP, symptoms of nasal congestion and loss of smell, and coexisting asthma will be recruited across 15 countries. The primary objective is to assess the efficacy of dupilumab compared to omalizumab in reducing the nasal polyp size and improving the sense of smell. The key secondary objectives are to evaluate the comparative efficacy in improving CRSwNP symptoms (eg, nasal congestion) and lung function. The safety will be evaluated in terms of treatment-emergent adverse events (AEs), serious AEs, and AEs of special interest. Conclusions EVEREST is the first head-to-head trial assessing the comparative efficacy and safety of 2 biologics in patients with severe CRSwNP and comorbid asthma. The study will provide evidence to help optimize treatment plans for patients that suffer from severe CRSwNP and comorbid asthma.
