RESUMEN

The brominated azo dye (BAD) Disperse Blue (DB79) is a widespread environmental pollutant. The long-term toxicological effects of DB79 and the mechanisms thereof must be understood to allow assessment of the risks of DB79 pollution. A dual-omics approach employing in silico analysis, bioinformatics, and in vitro bioassays was used to investigate the transgenerational (F0-F2) toxicity of DB79 in zebrafish at environmentally relevant concentrations and identify molecular initiating events and key events associated with DB79-induced fertility disorders. Exposure to 500 µg/L DB79 decreased fecundity in the F0 and F1 generations by > 30 % and increased the condition factor of the F1 generation 1.24-fold. PPARα/RXR and PXR ligand binding activation were found to be critical molecular initiating events associated with the decrease in fecundity. Several key events (changes in fatty acid oxidation and uptake, lipoprotein metabolism, and xenobiotic metabolism and transport) involved in lipid dysregulation and xenobiotic disposition were found to be induced by DB79 through bioinformatic annotation using dual-omics data. The biomolecular underpinnings of decreased transgenerational fertility in zebrafish attributable to BAD exposure were elucidated and novel biomolecular targets in the adverse outcome pathway framework were identified. These results will inform future studies and facilitate the development of mitigation strategies.

RESUMEN

Objective: In this retrospective cohort study, independent risk factors that influence untreatable progression (UP) and time to UP (TTUP) in patients with hepatocellular carcinoma (HCC) after locoregional interventional therapy were examined. The effects of initial response and best response on UP occurrence and TTUP after locoregional interventional therapy were evaluated. Methods: Data were collected from HCC patients who were initially treated with the drug-eluting beads-transcatheter arterial chemoembolization (DEB-TACE) procedure at our hospital from January 2017 to December 2022. Modified response evaluation criteria in solid tumors (m-RECIST) was used to evaluate the radiologic response of tumors. Logistic regression analysis was used to analyze the risk factors for UP in patients, and Cox regression analysis was used to discover independent variables that influenced TTUP. Results: A total of 93 patients who initially underwent the DEB-TACE procedure were included. Subsequent to initial treatment, 50 patients continued with DEB-TACE treatment, while 43 received DEB-TACE and sequential thermal ablation treatment. The probability of developing UP was 82.8% (n = 77). Furthermore, 49 (52.7%) patients achieved an initial response, and 70 (75.3%) achieved the best response. Multivariate logistic regression analysis confirmed three independent risk factors of UP, namely, age (odds ratio [OR]: 0.950, p = 0.044); initial response (OR: 0.177, p = 0.020); and treatment regimen (OR: 7.133, p = 0.007). Multivariate Cox regression found that total bilirubin (hazard ratio [HR]: 1.029, p = 0.002), tumor distribution (HR: 1.752, p = 0.034), Subjective Angiographic Chemoembolization Endpoint (SACE) classification (HR: 0.668, p = 0.043), number of tumors (HR: 1.130, p = 0.004), initial response (HR: 0.539, p = 0.019), and treatment regimen (HR: 4.615, p < 0.001) were independent variables that influenced TTUP. Conclusions: Age, initial response, and treatment regimen significantly affected the occurrence of UP in HCC patients. Initial response, SACE classification, treatment regimen, total bilirubin, number of tumors, and tumor distribution were significantly correlated with TTUP. The initial response following locoregional interventional therapy had greater effects on UP occurrence and TTUP than the best response.

RESUMEN

Transarterial chemoembolization (TACE), the mainstay treatment of unresectable primary liver cancer that primarily employs nondegradable drug-loaded embolic agents to achieve synergistic vascular embolization and locoregional chemotherapy effects, suffers from an inferior drug burst behavior lacking long-term drug release controllability that severely limits the TACE efficacy. Here we developed gelatin-based drug-eluting microembolics grafted with nanosized poly(acrylic acid) serving as a biodegradable ion-exchange platform that leverages a counterion condensation effect to achieve high-efficiency electrostatic drug loading with electropositive drugs such as doxorubicin (i.e., drug loading capacity >34 mg/mL, encapsulation efficiency >98%, and loading time <10 min) and an enzymatic surface-erosion degradation pattern (∼2 months) to offer sustained locoregional pharmacokinetics with long-lasting deep-tumor retention capability for TACE treatment. The microembolics demonstrated facile microcatheter deliverability in a healthy porcine liver embolization model, superior tumor-killing capacity in a rabbit VX2 liver cancer embolization model, and stabilized extravascular drug penetration depth (>3 mm for 3 months) in a rabbit ear embolization model. Importantly, the microembolics finally exhibited vessel remodeling-induced permanent embolization with minimal inflammation responses after complete degradation. Such a biodegradable ion-exchange drug carrier provides an effective and versatile strategy for enhancing long-term therapeutic responses of various local chemotherapy treatments.

RESUMEN

OBJECTIVES: Scalp acupuncture is a method of treating diseases by dividing and stimulating the corresponding function-oriented cortical scalp areas. It is a commonly used therapy for neurological disorders. However, the specific target selection for scalp acupuncture remains to be explored. This manuscript aims to initiate an attempt to develop/identify scalp acupuncture targets based on neuroimaging findings and noninvasive brain stimulation. METHODS: Neurosynth-based meta-analysis of neuroimaging studies was conducted to identify brain stimulation targets of neurological disorders. The identified target regions were further projected to the scalp. The traditional acupoints and 10-20 EEG system were referenced for the localization of these targets. In this study, the "mild cognitive impairment" (MCI), "Alzheimer's disease" (AD) and "dementia" were used as the retrieval terms respectively, and a unity detection method was used to generate brain maps, with the default FDR (false discovery rate, P<0.01) threshold of Neurosynth set for subsequent exploration of various disease-related brain regions. The literature search was conducted on July 30, 2022. RESULTS: The localization and manipulation suggestions of neuroimage-based scalp acupuncture targets for MCI, AD, and dementia were introduced in the present paper (part 2). Here are 3 target examples for each of these 3 diseases due to word limitation. 1) MCI:Based on the 81 papers retrieved, we identified 6 potential scalp acupuncture points for MCI, their corresponding brain regions, brain functions and the possible resultant effects of the scalp target acupoint stimulation respectively are as below. MCI1:the orbital part of the left inferior frontal gyrus (left Brodmann area [BA]47), related to semantic coding, working memory and episodic memory, improving semantic coding and memory function;MCI2:the anterior motor area/left anterior central gyrus (left BA6), the motor center area, improving MCI motor function;MCI3:the left medial temporal gyrus (left BA21), related to the processing of speech, visual space, language and word understanding, improving language and memory. 2) AD:Based on the 196 papers retrieved, we found 6 potential scalp acupuncture targets for AD, their corresponding brain regions and brain functions of the 3 example targets respectively are as below. AD1:the left medial temporal gyrus (left BA21), participating in language and semantic processing, sentence and word generation, intent expression, deductive reasoning;AD2:the left angular gyrus (left BA39), related to semantic processing, word reading and comprehension, memory retrieval, attention and spatial cognition, reasoning, etc.;AD3:the left fusiform/suboccipital gyrus (left BA37), related to semantic classification, text generation, sign language, phonology processing, etc. 3) Dementia:Based on the 142 papers retrieved, we found 4 potential scalp acupuncture targets for dementia, their corresponding brain regions, brain functions and the possible targets of the proposed scalp stimulation respectively are as below. D1 and D2:the left inferior frontal gyrus (i.e., left BA46, and left BA47, respectively), being closely related to working memory, emotional response regulation, melody and other processing processes, may be suitable for treating memory decline and advanced executive dysfunction in patients with dementia;D3:the left medial temporal gyrus (left BA21), an important brain region for various sensory integration, cognitive processing and memory functions, and emotional processing, may be suitable for temporal dementia. CONCLUSIONS: We identified scalp acupuncture targets for several common neurological disorders based on neuroimaging findings and noninvasive brain stimulation. The proposed targets may also be used for treating these disorders using nerve/brain stimulation methods.

RESUMEN

Herpes zoster (HZ) is an infectious disease caused by the reactivation of varicella zoster virus (VZV), with 68% of cases occurring in adults over 50 years of age. HZ/su (Shingrix®) was approved by the Food and Drug Administration in 2017 for the prevention of HZ in individuals ≥ 50 years of age and showed very good protection from HZ. However, due to the use of the adjuvant AS01B, adverse reactions caused by Shingrix are a concern. Aluminum hydroxide is the most commonly used adjuvant and is widely used in a variety of vaccines. We developed a recombinant zoster vaccine (code: LZ901) consisting of a tetramer of VZV glycoprotein E (gE) and a human Fc fusion protein expressed in CHO cells, an immune complex-like molecule that can be adsorbed with an aluminum hydroxide adjuvant. We compared the immunogenicity of LZ901 with that of HZ/su in BALB/c mice. The results showed that LZ901 induced levels of gE-specific IgG antibodies comparable to those induced by HZ/su, and the results of FAMA titers further demonstrated their similar neutralizing antibody abilities. Most importantly, LZ901 induced higher levels of cell-mediated immunity (CMI) (which plays a decisive role in the efficacy of zoster vaccines) than HZ/su in BALB/c mice. The numbers of cytokine-producing T cells in LZ901-vaccinated mice were significantly greater than those in v-vaccinated mice, and the proportions of CD4+ and CD8+ T cells producing at least two types of cytokines in LZ901-vaccinated mice were significantly greater than those in HZ/su-vaccinated mice.

RESUMEN

PDE1B had been found to be involved in various diseases, including tumors and non-tumors. However, little was known about the definite role of PDE1B in osteosarcoma. Therefore, we mined public data on osteosarcoma to reveal the prognostic values and immunological roles of the PDE1B gene. Three osteosarcoma-related datasets from online websites were utilized for further data analysis. R 4.3.2 software was utilized to conduct difference analysis, prognostic analysis, gene set enrichment analysis (GSEA), nomogram construction, and immunological evaluations, respectively. Experimental verification of the PDE1B gene in osteosarcoma was conducted by qRT-PCR and western blot, based on the manufacturer's instructions. The PDE1B gene was discovered to be lowly expressed in osteosarcoma, and its low expression was associated with poor OS (all P < 0.05). Experimental verifications by qRT-PCR and western blot results remained consistent (all P < 0.05). Univariate and multivariate Cox regression analyses indicated that the PDE1B gene had independent abilities in predicting OS in the TARGET osteosarcoma dataset (both P < 0.05). GSEA revealed that PDE1B was markedly linked to the calcium, cell cycle, chemokine, JAK STAT, and VEGF pathways. Moreover, PDE1B was found to be markedly associated with immunity (all P < 0.05), and the TIDE algorithm further shed light on that patients with high-PDE1B expression would have a better immune response to immunotherapies than those with low-PDE1B expression, suggesting that the PDE1B gene could prevent immune escape from osteosarcoma. The PDE1B gene was found to be a tumor suppressor gene in osteosarcoma, and its high expression was related to a better OS prognosis, suppressing immune escape from osteosarcoma.

RESUMEN

Importance: Black and Hispanic patients have high rates of recurrent stroke and uncontrolled hypertension in the US. The effectiveness of home blood pressure telemonitoring (HBPTM) and telephonic nurse case management (NCM) among low-income Black and Hispanic patients with stroke is unknown. Objective: To determine whether NCM plus HBPTM results in greater systolic blood pressure (SBP) reduction at 12 months and lower rate of stroke recurrence at 24 months than HBPTM alone among Black and Hispanic stroke survivors with uncontrolled hypertension. Design, Setting, and Participants: Practice-based, multicenter, randomized clinical trial in 8 stroke centers and ambulatory practices in New York City. Black and Hispanic study participants were enrolled between April 18, 2014, and December 19, 2017, with a final follow-up visit on December 31, 2019. Interventions: Participants were randomly assigned to receive either HBPTM alone (12 home BP measurements/week for 12 months, with results transmitted to a clinician; n = 226) or NCM plus HBPTM (20 counseling calls over 12 months; n = 224). Main Outcomes and Measures: Primary outcomes were change in SBP at 12 months and rate of recurrent stroke at 24 months. Final statistical analyses were completed March 14, 2024. Results: Among 450 participants who were enrolled and randomized (mean [SD] age, 61.7 [11.0] years; 51% were Black [n = 231]; 44% were women [n = 200]; 31% had ≥3 comorbid conditions [n = 137]; 72% had household income <$25 000/y [n = 234/324]), 358 (80%) completed the trial. Those in the NCM plus HBPTM group had a significantly greater SBP reduction than those in the HBPTM alone group at 12 months (-15.1 mm Hg [95% CI, -17.2 to -13.0] vs -5.8 mm Hg [95% CI, -7.9 to -3.7], respectively; P < .001). The between-group difference in SBP reduction at 12 months, adjusted for primary care physician clustering, was -8.1 mm Hg (95% CI, -11.2 to -5.0; P < .001) at 12 months. The rate of recurrent stroke was similar between both groups at 24 months (4.0% in the NCM plus HBPTM group vs 4.0% in the HBPTM alone group, P > .99). Conclusions and Relevance: Among predominantly low-income Black and Hispanic stroke survivors with uncontrolled hypertension, addition of NCM to HBPTM led to greater SBP reduction than HBPTM alone. Additional studies are needed to understand the long-term clinical outcomes, cost-effectiveness, and generalizability of NCM-enhanced telehealth programs among low-income Black and Hispanic stroke survivors with significant comorbidity.

RESUMEN

OBJECTIVES: Scalp acupuncture is a unique acupuncture method developed based on brain functional and pathophysiological knowledge. In past decades, there has been significant development in the understanding of the brain pathology of many neurological disorders through cutting-edge brain imaging techniques. Yet, these findings have not been incorporated into scalp acupuncture. In the present paper, we aimed to initiate an attempt to develop/identify scalp acupuncture targets based on neuroimaging findings. METHODS: Based on the meta-analysis of neuroimaging studies in the Neurosynth database platform (http://neurosynth.org/), the brain clusters related to neurological disorders were automatically identified according to the search terms "Parkinson's disease"(PD), "chronic pain"(CP), "aphasia"(APH), "dyslexia"(DYS), "mild cognitive impairment", "Alzheimer's disease" and "dementia". Subsequently, the discovered brain region clusters projected onto the brain surface and scalp surface were listed, and the peak points of the clusters projected to the scalp surface were proposed as the potential stimulation targets for the corresponding diseases. Further, by combining the traditional scalp acupoints (including the scalp acupuncture lines) with 10-20 EEG system sites, we made localization suggestions for scalp stimulation targets and made acupuncture operation suggestions by combining with the shape of the brain region clusters. The literature search was conducted on July 30, 2022. RESULTS: The localization and manipulation suggestions of neuroimage-based scalp acupuncture targets were introduced in two parts. This part (part 1) includes PD, CP, APH, and DYS. Here are 3 target examples of each of these 4 diseases simply introduced due to word limitation. 1) PD. Based on the 175 articles retrieved from Neurosynth, we identified 7 potential scalp acupuncture targets for PD, the locations of the acupuncture stimulation and the recommended acupuncture needle operation (RANO) as well as the corresponding brain regions (CBRs) respectively are as below. PD1:about 0.5 cun (1 cun≈33.3 mm) superior-posterior to the left Xuanlu (GB5);puncturing subcutaneously and forward-upward;the left premotor area, subfrontal cortex of the island, inferior frontal gyrus and middle frontal gyrus. PD2:about 1 cun lateral-inferior to the left Chengling (GB18);puncturing subcutaneously and backward-upward;the inferior parietal lobule and postcentral gyrus. PD3:about 0.5 cun lateral-anterior to the left GB18;puncturing subcutaneously and inward-backward;left anterior central gyrus and posterior central gyrus. 2) CP. Based on the retrieved 92 articles, we identified 8 potential scalp acupuncture targets, the location of the acupuncture stimulation and the RANO, and CBRs respectively are as below. CP1:about 1 cun anterior-inferior to the left Xuanli (GB8);puncturing subcutaneously and backward-inwards;the left inferior frontal gyrus orbitalis and pars triangularis. CP2:about 0.5 cun posterior-superior to the left GB5;puncturing subcutaneously and forward-upward;the left anterior central gyrus and premotor area. CP3:about 0.5 cun posterior-superior to the left GB8;puncturing subcutaneously and forward;left inferior central area/central sulci operculum (second somatosensory area). 3) APH. Based on the retrieved 82 papers, we identified 7 potential scalp acupuncture targets for APH, their locations, RANO, and CBRs respectively are as below. APH1:close to the left GB5;puncturing subcutaneously and forward-downward;left subfrontal gyrus operculi/triangularis. APH2:about 0.5 cun posterior to the left Hanyan (GB4);puncturing subcutaneously and backward-upward;the left anterior central gyrus and posterior central gyrus. APH3:about 0.5 cun anterior-inferior to the left Qubin (GB7);puncturing subcutaneously and backward-downward;left medial/superior temporal gyrus. 4) DYS. Based on the retrieved 76 researches, we identified 8 potential scalp acupuncture targets for DYS, their locations, RANO and CBRs respectively are as below. DYS1:about 1 cun anterior-inferior to the left GB5;puncturing subcutaneously and forward-upward;the pars triangularis of the left inferior frontal gyrus. DYS2:about 0.5 cun posterior-superior to the left GB5;puncturing subcutaneously and forward-downward;the left subfrontal gyrus operculum, pars triangularis and anterior central gyrus. DYS3:the midpoint between the left GB5 and GB18;puncturing subcutaneously and forward;the left anterior central gyrus and posterior central gyrus. CONCLUSIONS: We identified scalp acupuncture targets for several common neurological disorders based on neuroimaging evidence for clinical application and research. The proposed targets may also be used for treating these disorders using brain stimulation methods.

RESUMEN

Scalp acupuncture is a unique acupuncture method, developed based on the cerebral cortex localization. Neuroimaging technology enables the combination of contemporary brain science findings with the studies of scalp stimulation sites. In this study, based on the neuroimaging literature retrieved from Neurosynth platform, the scalp stimulation targets of common psychiatric diseases are developed, which provides the stimulation target protocol of scalp acupuncture for anxiety, bipolar disorder, major depressive disorder and post-traumatic stress disorder. The paper introduces the functions of the brain areas that are involved in each target and closely related to the diseases, and lists the therapeutic methods of common acupuncture and scalp acupuncture for each disease so as to provide the references for clinical practice. These targets can be used not only for the stimulation of scalp acupuncture, but also for the different neuromodulation techniques to treat related diseases.

RESUMEN

BACKGROUND: Knee osteoarthritis (KOA) is a chronic progressive osteoarthropathy. Chrysin's anti-KOA action has been demonstrated, however more research is needed to understand how chrysin contributes to KOA. METHODS: LPS/ATP-induced macrophages transfected with or without HMGB1 overexpression underwent 5 µg/mL chrysin. The cell viability and macrophage pyroptosis were examined by cell counting kit-8 and flow cytometer. In vivo experiments, rats were injected with 1 mg monosodium iodoacetate by the infrapatellar ligament of the bilateral knee joint to induce KOA. The histological damage was analyzed by Safranin O/Fast Green staining and hematoxylin and eosin staining. The PWT, PWL and inflammatory factors were analyzed via Von-Frey filaments, thermal radiometer and ELISA. Immunofluorescence assay examined the expressions of CGRP and iNOS. The levels of HMGB1/RAGE-, NLRP3-, PI3K/AKT- and neuronal ion channel-related markers were examined by qPCR and western blot. RESULTS: Chrysin alleviated macrophage pyroptosis by inhibiting HMGB1 and the repression of chrysin on HMGB1/RAGE pathway and ion channel activation was reversed by overexpressed HMGB1. HMGB1 facilitated neuronal ion channel activation through the RAGE/PI3K/AKT pathway. Chrysin could improve the pathological injury of knee joints in KOA rats. Chrysin suppressed the HMGB1-regulated RAGE/PI3K/AKT pathway, hence reducing KOA damage and peripheral sensitization. CONCLUSION: Chrysin mitigated neuropathic pain and peripheral sensitization in KOA rats by repressing the RAGE/PI3K/AKT pathway modulated by HMGB1.

RESUMEN

Importance: Resident-to-resident aggression in assisted living facilities can result in physical and psychological harm, but its prevalence is unknown. Objective: To estimate the prevalence of resident-to-resident aggression, including physical, verbal, and sexual, among residents in assisted living facilities. Design, Setting, and Participants: This study used cross-sectional, observational data from a clinical trial, in which residents of assisted living facilities were monitored for events over a 1-month period. All residents of 14 large facilities randomly selected from 2 geographic locations (N = 1067), except those receiving hospice care (n = 11), were invited to participate; 93 died or moved prior to enrollment. There were 33 family and resident refusals; 930 residents were enrolled. Data were collected between May 30, 2018, and August 11, 2022. Main Outcomes and Measures: The data are from a clinical trial testing the effectiveness of an intervention to reduce resident-to-resident aggression. In addition, the study was designed to assess prevalence using the Time 1 (baseline) data, using a probability sample of facilities to allow for this analysis. Resident-to-resident aggression was identified using a mixed-method, case-finding strategy involving 6 sources: (1) cognitively capable resident reports regarding 22 possible events, (2) direct care staff report, (3) staff member reports collected from event-reporting forms, (4) research assistant observation of events in real time, (5) facility accident or incident reports, and (6) resident records. Results: The prevalence of resident-to-resident aggression among the 930 participants (mean [SD] age, 88.0 [7.2] years; 738 women [79.4%]) during the past month was estimated to be 15.2% (141 of 930 residents; 95% CI, 12.1%-18.8%). The most common forms of aggression included verbal (11.2% [104 of 930 residents; 95% CI, 8.8%-14.2%]), physical (41 of 930 residents; 4.4% [95% CI, 3.1%-6.3%]), sexual (0.8% [7 of 930 residents; 95% CI, 0.4%-1.6%]), and other (70 of 930 residents; 7.5% [95% CI, 5.5%-10.2%]). These categories are not mutually exclusive as residents could be involved with more than 1 type of aggressive behavior. Conclusions and Relevance: In this cross-sectional, observational prevalence study, resident-to-resident aggression in assisted living facilities was highly prevalent. Verbal aggression was the most common form, and physical aggression also occurred frequently. The effects of resident-to-resident aggression can be both morbid and mortal; therefore, intervention research is needed to prevent it and to treat it when it occurs.

RESUMEN

BACKGROUND: Colorectal cancer (CRC) is the second most lethal cancer in the United States (U.S.) with the highest incidence and mortality rates among African Americans (AAs) compared to other racial groups. Despite these disparities, AAs are the least likely to undergo CRC screening, have precancerous colorectal polyps removed, and have CRC detected at stages early enough for curative excision. In addition, compelling evidence links inflammatory dietary patterns to increased CRC and cardiovascular disease risk. Studies show that AA churches can successfully engage in health promotion activities including those related to cancer control. The current study seeks to leverage church-placed Community Health Workers (CHWs) to increase CRC screening and reduce CRC risk. DESIGN AND METHODS: We aim to (1) increase guideline concordant CRC screening uptake using church-placed CHWs trained in screening with a validated instrument, Brief Intervention using Motivational Interviewing, and Referral to Treatment (SBIRT); and (2) reduce dietary risk factors (inflammatory dietary patterns) linked to CRC. The latter will be addressed by culturally adapting an existing, web-based lifestyle program called Alive!. Using a Hybrid Type 1 Implementation-Effectiveness cluster randomized design, we will randomize 22 AA churches into either the dual intervention arm (CHW-led SBIRT intervention plus Alive!) or a usual care arm comprised of CRC prevention educational pamphlets and a list of CRC screening sites. We will recruit 440 subjects and evaluate the effects of both arms on screening uptake (colonoscopy, fecal DNA) (primary outcome) and dietary inflammation score (secondary outcome) at 6-month follow-up, and Life Simple7 (LS7)-a cardiovascular disease (CVD) risk score-at 6 months and 1 year (secondary outcome). Finally, guided by a racism-conscious adaptation of the Consolidated Framework for Implementation Research (CFIR), we will conduct a mixed-methods process evaluation with key stakeholders to understand multi-level influences on CRC screening and CVD risk behaviors. DISCUSSION: Church-placed CHWs are trusted influential connectors between communities and health systems. Studies have shown that these CHWs can successfully implement health prevention protocols in churches, including those related to cancer control, making them potentially important community mediators of CRC screening uptake and CRC/CVD risk reduction.

RESUMEN

The titanium alloy components utilized in the aviation field are typically large in size and possess complex structures. By utilizing multiple additive manufacturing processes, the precision and efficiency requirements of production can be met. We investigated the hybrid additive manufacturing of Ti-6Al-4V using a combination of cold metal transfer additive manufacturing (CMTAM) and laser metal deposition (LMD), as well as the feasibility of using the CMT-LMD hybrid additive manufacturing process for fabricating Ti-6Al-4V components. Microstructural examinations, tensile testing coupled with digital image correlation and dynamic compressive experiments (by the split Hopkinson pressure bar (SHPB) system) were employed to assess the parts. The results indicate that the interface of the LMD and CMTAM zone formed a compact metallurgical bonding. In the CMTAM and LMD zone, the prior-ß grains exhibit epitaxial growth, forming columnar prior-ß grains. Due to laser remelting, the CMT-LMD hybrid additive zone experiences grain refinement, resulting in equiaxed prior-ß grains at the interface with an average grain size smaller than that of the CMTAM and LMD regions. The microstructures reveal significant differences in grain orientation and morphology among the zones, with distinct textures forming in each zone. In the CMT-LMD hybrid zone, due to interfacial strengthening, strain concentration occurs in the arc additive zone during tensile testing, leading to fracture on the CMTAM zone. Under high-strain-rate dynamic impact conditions, the LMD region exhibits ductile fracture, while the CMTAM zone demonstrates brittle fracture. The hybrid zone combines ductile and brittle fracture modes, and the CMT-LMD hybrid material exhibits superior dynamic impact performance compared to the single deposition zone.

RESUMEN

OBJECTIVE: The efficacy of single-incision plus one-port laparoscopic surgery (SILS + 1) versus conventional laparoscopic surgery (CLS) for colorectal cancer treatment remains unclear. This study compares the short-term and long-term outcomes of SILS + 1 and CLS using a high-quality systematic review and meta-analysis. METHOD: Literature search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, drawing from PubMed, Embase, Web of Science, and the Cochrane Library until December 10, 2023. Statistical analysis was conducted using RevMan and Stata. RESULT: The review and meta-analysis included seven studies with 1740 colorectal cancer patients. Compared to CLS, SILS + 1 showed significant improvements in operation time (WMD = - 18.33, P < 0.00001), blood loss (WMD = - 21.31, P < 0.00001), incision length (WMD = - 2.07, P < 0.00001), time to first defecation (WMD = - 14.91, P = 0.009), time to oral intake (WMD = - 11.46, P = 0.04), and time to ambulation (WMD = - 11.52, P = 0.01). There were no significant differences in lymph node harvest, resection margins, complications, anastomotic leakage, hospital stay, disease-free survival, overall survival, and postoperative recurrence. CONCLUSIONS: Compared to CLS, SILS + 1 demonstrates superiority in shortening the surgical incision and promoting postoperative recovery. SILS + 1 can provide a safe and feasible alternative to CLS.

RESUMEN

Objective: This study aims to explore the relationship between physical activity (PA) and postoperative delirium (POD). Methods: We selected 400 patients from the Perioperative Neurocognitive Disorder and Biomarkers Lifestyle (PNDABLE) database, and the patients in the PNDABLE database were sampled and tested Alzheimer's biomarkers. The diagnosis of POD was made using the Confusion Assessment Scale (CAM) and the severity was assessed using Memorial Delirium Assessment Scale (MDAS). Mini-Mental State Examination (MMSE) scale was used to detect the mental state of the patients. Enzyme-linked immunosorbent assay (ELISA) was used to detect the level of preoperative cerebrospinal fluid (CSF) biomarkers, such as amyloid ß plaque 42 (Aß42), total tau protein (T-tau), and phosphorylated tau protein (P-tau). Logistic regression, sensitivity analysis, and post hoc analysis were used to explore the relationship between risk and protective factors on POD. We used the mediating effect to explore whether PA mediates the occurrence of POD through CSF biomarkers. Results: The incidence of POD was 17.5%. According to our research, the consequence prompted that PA might be the protective factor for POD [odds ratio (OR): 0.336, 95% confidence interval (95 CI) 0.206-0.548, P < 0.001]. The result of logistic regression revealed that CSF biomarker Aß42 (OR: 0.997, 95 CI 0.996-0.999, P < 0.001) might be a protective factor against POD, and the T-tau (OR: 1.006, 95 CI 1.003-1.009, P = 0.001) and P-tau (OR: 1.039, 95 CI 1.018-1.059, P < 0.001) might risk factors for POD. Sensitivity analysis confirmed the correlation between PA and CSF biomarkers in the patients with POD. Mediation effect analysis showed that PA may reduce the occurrence of POD partly through CSF biomarkers, such as Aß42 (proportion: 11%, P < 0.05), T-tau (proportion: 13%, P < 0.05), and P-tau (proportion: 12%, P < 0.05). Conclusion: Physical activity is probably a protective factor for POD and may exert a mediating effect through CSF biomarkers.

RESUMEN

Aiming at the weak performance of chaotic light output in semiconductor laser systems, the study designed a power control algorithm for semiconductor laser drive systems based on linear self-disturbance rejection control. Then the optimization parameters and scope were determined, and multi-objective optimization and direction preference algorithms were introduced. A chaotic optical performance optimization model based on improved multi-objective genetic algorithm was constructed using adaptive functions as evaluation indicators. These results confirmed that the larger the bandwidth of the controller, the faster the response speed of the resonant converter, but the stability was poor. When the input voltage underwent a sudden change, the current ripple coefficient of the PID algorithm was 0.55%. The linear active disturbance rejection control algorithm could ensure that the voltage and current maintained at the set values, and the output current of the algorithm was more stable when the load underwent sudden changes. The directional preference algorithm could further provide more valuable solutions on the basis of adaptive genetic algorithms. When the peak value of the autocorrelation function was equal to 0.2, the delay characteristics of chaotic light were effectively suppressed, having strong signal bandwidth and complexity. In summary, the constructed model has good application effects in optimizing chaotic optical performance and has certain positive significance for communication security.
