RESUMEN

Alkynyl amides play crucial roles in organic synthesis in the production of bioactive compounds and valuable heterocycles. Despite numerous studies on their synthesis, challenges persist due to the necessity of harsh or hazardous conditions and the use of costly or unstable reagents. Herein, we present a one-pot method for the synthesis of all three bonds of the alkyne under transition-metal free conditions. An important feature of this chemistry is the use of readily available feedstock chemicals, such as methyl esters and acetamides. This approach offers efficient access to a wide range of aryl and alkyl alkynyl amides and demonstrates excellent tolerance towards various functional groups in a sustainable and cost-effective manner.

RESUMEN

Musical training has been associated with enhanced neural processing of sounds, as measured via the frequency following response (FFR), implying the potential for human subcortical neural plasticity. We conducted a large-scale multi-site preregistered study (n > 260) to replicate and extend the findings underpinning this important relationship. We failed to replicate any of the major findings published previously in smaller studies. Musical training was related neither to enhanced spectral encoding strength of a speech stimulus (/da/) in babble nor to a stronger neural-stimulus correlation. Similarly, the strength of neural tracking of a speech sound with a time-varying pitch was not related to either years of musical training or age of onset of musical training. Our findings provide no evidence for plasticity of early auditory responses based on musical training and exposure.

RESUMEN

Importance: Patient-directed educational materials are a promising implementation strategy to expand deprescribing reach and adoption, but little is known about the impact across medication groups with potentially different perceived risks. Objective: To examine the impact of a patient-directed education intervention on clinician deprescribing of potentially low-benefit (proton pump inhibitors) or high-risk medications (high-dose gabapentin, diabetes agents with hypoglycemia risks). Design, Setting, and Participants: This pragmatic multisite nonrandomized clinical trial took place at 3 geographically distinct US Veterans Affairs (VA) medical centers from April 2021 to October 2022. The total study sample was composed of the intervention cohort and the historical control cohort cared for by 103 primary care practitioners (PCPs). Intervention: The primary intervention component was a medication-specific brochure, mailed during the intervention time frame to all eligible patients 2 to 3 weeks prior to upcoming primary care appointments. Patients seen by the same PCPs at the same sites 1 year prior to the study intervention served as controls. Main Outcome and Measures: The primary binary outcome variable was deprescribing 6 months after the intervention, defined as complete cessation or any dose reduction of the target medication using VA pharmacy dispensing data. Results: The total study sample included 5071 patients. The overall rate of deprescribing among the intervention cohort (n = 2539) was 29.5% compared with 25.8% among the controls (n = 2532). In an unadjusted model, the intervention cohort was statistically significantly more likely to have deprescribing (odds ratio [OR], 1.17 [95% CI, 1.03-1.33]; P = .02). In a multivariable logistic regression model nesting patients within PCPs within sites and controlling for patient and PCP characteristics, the odds of deprescribing in the intervention cohort were 1.21 times that of the control cohort (95% CI, 1.05-1.38; P = .008). The difference in deprescribing prevalence between the intervention and control cohorts (proton pump inhibitors: 29.4% vs 25.4%; gabapentin: 40.2% vs 36.2%; hypoglycemia risk: 27.3% vs 25.1%) did not statistically significantly differ by medication group (P = .90). Conclusion and Relevance: This nonrandomized clinical trial found that patient-directed educational materials provided prior to scheduled primary care appointments can effectively promote deprescribing for potentially low-benefit and high-risk medication groups. Trial Registration: ClinicalTrials.gov Identifier: NCT0429490.

RESUMEN

Bilateral cochlear implant (BiCI) usage makes binaural benefits a possibility for implant users. Yet, limited access to interaural time difference (ITD) cues and reduced saliency of interaural level difference (ILD) cues restricts perceptual benefits of spatially separating a target from masker sounds for BiCI users. Here, we explore whether magnifying ILD cues improves intelligibility of masked speech for BiCI listeners in a "symmetrical-masker" configuration, which controls for long-term positive target-to-masker ratio (TMR) at the ear nearer the target from naturally occurring ILD cues. We magnified ILDs by estimating moment-to-moment ITDs in 1-octave-wide frequency bands, and applying corresponding ILDs to the target-masker mixtures reaching the two ears at each time in each frequency band. We conducted two experiments, one with NH listeners using vocoded stimuli and one with BiCI users. ILD magnification significantly improved intelligibility in both experiments. BiCI listeners showed no benefit of spatial separation between target and maskers with natural ILDs, even for the largest target-masker separation. Because ILD magnification is applied to the mixed signals at each ear, the strategy does not alter the TMR in either ear at any time; improvements to masked speech intelligibility are thus likely from improved perceptual separation of the competing sources.

RESUMEN

BACKGROUND: Co-occurring chronic pain and posttraumatic stress disorder (PTSD) is associated with poorer physical and mental functioning and well-being. Treatments often incorporate goal-setting around personally meaningful behaviors; however, it is unclear whether intentionally focusing on improving meaning and purpose in life (i.e., meaning-as-goal) may also serve as a helpful treatment target. The objective of the current study is to determine whether reported progress toward meaning-as-goal at 6 months is associated with pain severity and interference, physical and mental health functioning, and global meaning and purpose at 6- and 12-months. METHODS: Data were collected as part of an evaluation effort focused on VA's Whole Health System implementation efforts. VA electronic health records were linked to survey data across three time points (baseline, 6 months, and 12 months) from Veterans with both chronic pain and PTSD across 18 VA sites. A total of 1341 Veterans met inclusion criteria (mean age = 62, SD = 11.7). RESULTS: Regression analyses showed that progress toward meaning-as-goal was significantly associated with all 6-month variables, with standardized coefficients ranging from - 0.14 (pain severity and interference) to .37 (global meaning and purpose), in addition to all 12-month variables, with standardized coefficients ranging from - .13 (pain severity and interference) to .31 (global meaning and purpose). CONCLUSIONS: Efforts to intentionally promote meaning and purpose as part of evidence-based treatment for chronic pain and PTSD may lead to decreased pain and improved physical and mental health functioning and global meaning and purpose. With coefficients ranging from small to moderate effect sizes, more work is needed to better understand how best to maximize meaning-related goals.

RESUMEN

Background: Population-based cancer registries are the best source of information to measure cancer burden. However, little is done to use this information for individual cancer risk assessment. In this study, we aimed at identifying women at high risk of breast and ovarian cancer using data on family history of cancer from the Israel national cancer registry. Methods: We used the family history assessment tool (FHAT) to score all females, 26 to 45 years of age, in a 2.6-million-member health provider in Israel (Maccabi Healthcare Services). Data on breast, ovarian, prostate, and pancreatic cancer history among the participants and their parents (identified using the national census) were retrieved from the national cancer registry. These data were used to calculate individual FHAT scores. Results: A total of 377,931 eligible women were included in the analysis. A relevant family history of cancer was detected in 20,386 (5.4%), with FHAT scores ranging from 1 to 16. FHAT score was higher in older women and among those with a history of breast cancer. Among women aged 35-39, an FHAT score of 10 or above was associated with an OR of 15.23 (95%CI: 7.41-28.19) for breast cancer compared to women with an FHAT of 0. Conclusions: Using individual-level data from national cancer registries may assist in detecting women with a relevant family history of cancer.

RESUMEN

Treatment with glucagon-like peptide 1 receptor agonists reduces liver steatosis and cardiometabolic risk (CMR). Few data are available on lipid metabolism, and no information is available on the postprandial lipidomic profile. Thus, we investigated how exenatide treatment changes lipid metabolism and composition during fasting and after a mixed-meal tolerance test (MMTT) in adults with severe obesity without diabetes. Thirty individuals (26 females and 4 males, 30-60 years old, BMI >40 kg/m2, HbA1c 5.76%) were assigned (1:1) to diet with exenatide 10 µg twice daily treatment (n = 15) or without treatment as control (n = 15) for 3 months. Fasting and postprandial lipidomic profile (by liquid chromatography quadrupole time-of-flight mass spectrometry) and fatty acid metabolism (following a 6-h MMTT/tracer study) and composition (by gas chromatography-mass spectrometry) were evaluated before and after treatment. Both groups had slight weight loss (-5.5% vs. -1.9%, exenatide vs. control; P = 0.052). During fasting, exenatide, compared with control, reduced some ceramides (CERs) and lysophosphatidylcholines (LPCs) previously associated with CMR, while relatively increasing unsaturated phospholipid species (phosphatidylcholine [PC], LPC) with protective effects on CMR, although concentrations of total lipid species were unchanged. During MMTT, both groups showed suppressed lipolysis equal to baseline, but exenatide significantly lowered free fatty acid clearance and postprandial triacyclglycerol (TAG) concentrations, particularly saturated TAGs with 44-54 carbons. Exenatide also reduced some postprandial CERs, PCs, and LPCs previously linked to CMR. These changes in lipidomic profile remained statistically significant after adjusting for weight loss. Exenatide improved fasting and postprandial lipidomic profiles associated with CMR mainly by reducing saturated postprandial TAGs and CERs independently of weight loss and diabetes.

RESUMEN

Background: Patients with high-grade glioma have high palliative care needs, yet few receive palliative care consultation. This study aims to explore themes on (1) benefits of primary (delivered by neuro-oncologists) and specialty palliative care (SPC) and (2) barriers to SPC referral, according to a diverse sample of clinicians. Methods: From September 2021 to May 2023, 10 palliative physicians and 10 neuro-oncologists were recruited via purposive sampling for diversity in geographic setting, seniority, and practice structure. Semistructured, 45-minute interviews were audio-recorded, professionally transcribed, and coded by 2 investigators. A qualitative, phenomenological approach to thematic analysis was used. Results: Regarding primary palliative care, (1) neuro-oncologists have primary ownership of cancer-directed treatment and palliative management and (2) the neuro-oncology clinic is glioma patients' medical home. Regarding SPC, (1) palliative specialists' approach is beneficial even without disease-specific expertise; (2) palliative specialists have time to comprehensively address palliative needs; and (3) earlier SPC enhances its benefits. For referral barriers, (1) appointment burden can be mitigated with telehealth, home-based, and embedded palliative care; (2) heightened stigma associating SPC with hospice in a population with high death anxiety can be mitigated with earlier referral to promote rapport-building; and (3) lack of neuro-oncologic expertise among palliative specialists can be mitigated by emphasizing their role in managing nonneurologic symptoms, coping support, and anticipatory guidance. Conclusions: These themes emphasize the central role of neuro-oncologists in addressing palliative care needs in glioma, without obviating the need for or benefits of SPC. Tailored models may be needed to optimize the balance of primary and specialty palliative care in glioma.

RESUMEN

This paper presents an innovative application of chitosan material to be used as pH-responsive valves for the precise control of lateral flow in microfluidic paper-based analytical devices (µPADs). The fabrication of µPADs involved wax printing, while pH-responsive valves were created using a solution of chitosan in acetic acid. The valve-forming solution was applied, and ready when dry; by exposure to acidic solutions, the valve opens. Remarkably, the valves exhibited excellent compatibility with alkaline, neutral, and acidic solutions with a pH higher than 4. The valve opening process had no impact on the flow rate and colorimetric analysis. The potential of chitosan valves used for flow control was demonstrated for µPADs employed for nitrate determination. Valves were used to increase the conversion time of nitrate to nitrite, which was further analyzed using the Griess reaction. The µPAD showed a linear response in the concentration range of 10-100 µmol L-1, with a detection limit of 5.4 µmol L-1. As a proof of concept, the assay was successfully applied to detect nitrate levels in water samples from artificial lakes of recreational parks. For analyses that require controlled kinetics and involve multiple sequential steps, the use of chitosan pH-responsive valves in µPADs is extremely valuable. This breakthrough holds great potential for the development of simple and high-impact microfluidic platforms that can cater to a wide range of analytical chemistry applications.

RESUMEN

The viral nuclear egress complex (NEC) allows herpesvirus capsids to escape from the nucleus without compromising the nuclear envelope integrity. The NEC lattice assembles on the inner nuclear membrane and mediates the budding of nascent nucleocapsids into the perinuclear space and their subsequent release into the cytosol. Its essential role makes it a potent antiviral target, necessitating structural information in the context of a cellular infection. Here we determined structures of NEC-capsid interfaces in situ using electron cryo-tomography, showing a substantial structural heterogeneity. In addition, while the capsid is associated with budding initiation, it is not required for curvature formation. By determining the NEC structure in several conformations, we show that curvature arises from an asymmetric assembly of disordered and hexagonally ordered lattice domains independent of pUL25 or other viral capsid vertex components. Our results advance our understanding of the mechanism of nuclear egress in the context of a living cell.

RESUMEN

CONTEXT: Early palliative care referral is recommended broadly in oncology. Yet, few patients with high-grade gliomas (HGG) - highly aggressive brain tumors - receive specialty palliative care consultation. OBJECTIVES: To delineate unique needs of HGG patients relative to other oncology patients according to perceptions of a diverse sample of US palliative medicine physicians and neuro-oncologists in each of the eight domains of palliative care; and to describe contrasts between physician specialties on indications for and timing of specialty palliative care referrals in HGG. METHODS: Between September 2021 and May 2023, we conducted semi-structured, 40-minute interviews with ten palliative medicine physicians and ten neuro-oncologists. Participants were recruited via purposive sampling for diversity in geographic setting, years in practice, and practice structure. Interviews were audio-recorded, professionally transcribed, and coded by two investigators. Data were analyzed thematically using a qualitative, phenomenological approach. RESULTS: The palliative care needs of HGG relative to other cancers across palliative care domains are distinguished by poor prognosis, physical and cognitive deficits, and neuropsychiatric symptoms. Themes on indications for palliative care referral differed between neuro-oncologists and palliative physicians. Neuro-oncologists favored selective referral for clinical indications such as high non-neurologic symptom burden requiring time-intensive management. Palliative physicians favored early referral of most HGG patients, to allow for maximal benefit across HGG trajectory. CONCLUSION: Patients with HGG have unique palliative care needs that affect palliative care delivery across care domains. Bidirectional education, enhanced collaboration, and consensus guidelines may help overcome barriers to specialty palliative care referral.

RESUMEN

Sepsis-associated encephalopathy, which manifests in severe cognitive and depressive symptoms, is directly linked to neuroinflammation. Our study investigates the efficacy of 25H-NBOMe, a phenethylamine, in alleviating these symptoms, potentially offering an innovative treatment for post-sepsis depression. Wistar rats, weighing between 250-300 g, were subjected to cecal ligation and puncture (CLP) surgery to induce sepsis. Depressive-like behaviors were assessed using the forced swim test (FST) on either day 7 or 14 post-surgery, to establish the presence of depressive symptoms. The impact of 25H-NBOMe treatment was then evaluated, focusing on the head-twitch response (HTR), performance in the FST, and GFAP expression in the prefrontal cortex. Treatment with 25H-NBOMe resulted in significant behavioral changes, demonstrated by decreased immobility and increased swimming times in the FST, along with a rise in the HTR. These outcomes indicate a reduction in depressive-like symptoms post-sepsis and the psychoactive effects of the compound. Furthermore, a notable decrease in GFAP expression in the study highlights the compound's impact on mitigating sepsis-induced astrogliosis. This study demonstrates the effectiveness of 25H-NBOMe, a psychedelic in the phenethylamine class, in treating post-sepsis depression and reducing astrogliosis. However, the psychedelic nature of 25H-NBOMe calls for further investigation into similar compounds with less psychoactive impact, crucial for advancing treatment options for neuropsychiatric symptoms following sepsis.

RESUMEN

In this present study, carried out between November 2020 and July 2023 at Londrina's University Hospital, patients with active lesions of cutaneous leishmaniasis (CL) were analyzed regarding pain perception and anatomopathological aspects of the ulcers. Pain was assessed using a numerical rating scale (NRS) to compare five patients diagnosed with CL with four control patients diagnosed with vascular skin ulcers. Histopathological evaluations were used to investigate the nociceptor neuron-Leishmania interface. Patients with CL ulcers reported less pain compared to patients with vascular ulcers (2.60 ± 2.30 and 7.25 ± 0.95, respectively, p = 0.0072). Histopathology evidenced Leishmania spp. amastigote forms nearby sensory nerve fibers in profound dermis. Schwann cells marker (S100 protein) was detected, and caspase-3 activation was not evidenced in the in the nerve fibers of CL patients' samples, suggesting absence of apoptotic activity in nerve endings. Additionally, samples taken from the active edge of the lesion were negative for bacilli acid-alcohol resistant (BAAR), which excludes concomitant leprosy, in which painless lesions are also observed. Thus, the present data unveil for the first time anatomopathological and microbiological details of painless ulcers in CL patients, which has important clinical implications for a better understanding on the intriguing painless clinical characteristic of CL.

RESUMEN

BACKGROUND: Acupuncture and chiropractic care are evidence-based pain management alternatives to opioids. The Veterans Health Administration (VA) provides this care in some VA facilities, but also refers patients to community providers. We aimed to determine if patient-reported outcomes differ for acupuncture and chiropractic care from VA versus community providers. MATERIALS AND METHODS: We conducted an observational study using survey outcome data and electronic medical record utilization data for acupuncture and chiropractic care provided in 18 VA facilities or in community facilities reimbursed by VA. Study participants were users of VA primary care, mental health, pain clinic, complementary and integrative therapies, coaching or education services in 2018-2019. Patients received 1) 4+ acupuncture visits (N = 201) or 4+ chiropractic care visits (N = 178) from a VA or community provider from 60 days prior to baseline to six-months survey and 2) no acupuncture or chiropractic visits from 1 year to 60 days prior to baseline. Outcomes measured included patient-reported pain (PEG) and physical health (PROMIS) at baseline and six-month surveys. Multivariate analyses examined outcomes at six months, adjusting for baseline outcomes and demographics. RESULTS: In unadjusted analyses, pain and physical health improved for patients receiving community-based acupuncture, while VA-based acupuncture patients experienced no change. Unadjusted analyses also showed improvements in physical health, but not pain, for patients receiving VA-based chiropractic care, with no changes for community-based chiropractic care patients. Using multivariate models, VA-based acupuncture was no different from community-based acupuncture for pain (-0.258, p = 0.172) or physical health (0.539, p = 0.399). Similarly, there were no differences between VA- and community-based chiropractic care in pain (-0.273, p = 0.154) or physical health (0.793, p = 0.191). CONCLUSIONS: Acupuncture and chiropractic care were associated with modest improvements at six months, with no meaningful differences between VA and community providers. The choice to receive care from VA or community providers could be based on factors other than quality, like cost or convenience.

RESUMEN

Hearing-impaired listeners struggle to understand speech in noise, even when using cochlear implants (CIs) or hearing aids. Successful listening in noisy environments depends on the brain's ability to organize a mixture of sound sources into distinct perceptual streams (i.e., source segregation). In normal-hearing listeners, temporal coherence of sound fluctuations across frequency channels supports this process by promoting grouping of elements belonging to a single acoustic source. We hypothesized that reduced spectral resolution-a hallmark of both electric/CI (from current spread) and acoustic (from broadened tuning) hearing with sensorineural hearing loss-degrades segregation based on temporal coherence. This is because reduced frequency resolution decreases the likelihood that a single sound source dominates the activity driving any specific channel; concomitantly, it increases the correlation in activity across channels. Consistent with our hypothesis, predictions from a physiologically plausible model of temporal-coherence-based segregation suggest that CI current spread reduces comodulation masking release (CMR; a correlate of temporal-coherence processing) and speech intelligibility in noise. These predictions are consistent with our behavioral data with simulated CI listening. Our model also predicts smaller CMR with increasing levels of outer-hair-cell damage. These results suggest that reduced spectral resolution relative to normal hearing impairs temporal-coherence-based segregation and speech-in-noise outcomes.

RESUMEN

OBJECTIVE: This study evaluates the amplitude of the anatomical-mechanical angle (AMA-angle) using 4 measuring methods of the tibial distal anatomical axes (DAA) previously described, comparing the literature results to determine if there are significant differences in patients with cranial cruciate ligament (CrCL) rupture. ANIMALS: This study was comprised of 30 tibiae (29 dogs), including 1 bilateral case. METHODS: A retrospective study was selected for this research. DAA measurements were performed on all surgically confirmed cases of canine CrCL rupture at Hospital Veterinário de Especialidades Bruselas from 2019 to 2022. Four different published methods (identified by surname of the corresponding author of the original publication) were compared. Tibial measurements were made using Veterinary Preoperative Orthopedic Planning Pro software (https://vpop-pro.com/) on mediolateral radiographic projections obtained from a digital database. RESULTS: The mean (range) in the DAA method conducted by Hulse obtained a AMA-angle of 5.4° (3.3 to 8.1°), 3.0° (0 to 5.8°) for Osmond et al, 3.2° (0.9 to 6°) for Miles, and 5.9° (2.4 to 8.8°) for Tudury. Differences among the means of the AMA-angle of the authors methods were found with a statistical difference (P < .05), except between Osmond and Miles. The mean AMA-angle with the Osmond method concurred with previous study results that determined the magnitude using the same measurement method of DAA in patients with CrCL rupture. CLINICAL RELEVANCE: The AMA-angle magnitude has been associated with higher sensitivity and specificity for predicting the development of CrCL rupture compared to other anatomical factors evaluated; therefore, future comparisons with different methods of measurement of the DAA between healthy and affected patients are recommended to determine whether any of them can increase the percentage value as a predictive factor for the occurrence of this condition.

RESUMEN

Background: Assessing the use and effectiveness of complementary and integrative health (CIH) therapies via survey can be complicated given CIH therapies are used in various locations and formats, the dosing required to have an effect is unclear, the potential health and well-being outcomes are many, and describing CIH therapies can be challenging. Few surveys assessing CIH therapy use and effectiveness exist, and none sufficiently reflect these complexities. Objective: In a large-scale Veterans Health Administration (VA) quality improvement effort, we developed the "Complementary and Integrative Health Therapy Patient Experience Survey", a longitudinal, electronic patient self-administered survey to comprehensively assess CIH therapy use and outcomes. Methods: We obtained guidance from the literature, subject matter experts, and Veteran patients who used CIH therapies in designing the survey. As a validity check, we completed cognitive testing and interviews with those patients. We conducted the survey (March 2021-April 2023), inviting 15,608 Veterans with chronic musculoskeletal pain with a recent CIH appointment or referral identified in VA electronic medical records (EMR) to participate. As a second validity check, we compared VA EMR data and patient self-reports of CIH therapy utilization a month after survey initiation and again at survey conclusion. Results: The 64-item, electronic survey assesses CIH dosing (amount and timing), delivery format and location, provider location, and payor. It also assesses 7 patient-reported outcomes (pain, global mental health, global physical health, depression, quality of life, stress, and meaning/purpose in life), and 3 potential mediators (perceived health competency, healthcare engagement, and self-efficacy for managing diseases). The survey took 17 minutes on average to complete and had a baseline response rate of 45.3%. We found high degrees of concordance between self-reported and EMR data for all therapies except meditation. Conclusions: Validly assessing patient-reported CIH therapy use and outcomes is complex, but possible.

RESUMEN

INTRODUCTION: Depression is a risk factor and possible prodromal symptom of Alzheimer's disease (AD), but little is known about subsequent risk of developing depression in persons with AD. METHODS: National matched cohort study was conducted of all 129,410 persons diagnosed with AD and 390,088 with all-cause dementia during 1998-2017 in Sweden, and 3,900,880 age- and sex-matched controls without dementia, who had no prior depression. Cox regression was used to compute hazard ratios (HRs) for major depression through 2018. RESULTS: Cumulative incidence of major depression was 13% in persons with AD and 3% in controls. Adjusting for sociodemographic factors and comorbidities, risk of major depression was greater than two-fold higher in women with AD (HR, 2.21; 95% confidence interval [CI], 2.11-2.32) or men with AD (2.68; 2.52-2.85), compared with controls. Similar results were found for all-cause dementia. DISCUSSION: Persons diagnosed with AD or related dementias need close follow-up for timely detection and treatment of depression. Highlights: In a large cohort, women and men with AD had >2-fold subsequent risk of depression.Risks were highest in the first year (>3-fold) but remained elevated ≥3 years later.Risk of depression was highest in persons aged ≥85 years at AD diagnosis.Persons with AD need close follow-up for detection and treatment of depression.

RESUMEN

Listeners performed two different tasks in which they remembered short sequences comprising either complex tones (generally heard as one melody) or everyday sounds (generally heard as separate objects). In one, listeners judged whether a probe item had been present in the preceding sequence. In the other, they judged whether a second sequence of the same items was identical in order to the preceding sequence. Performance on the first task was higher for everyday sounds; performance on the second was higher for complex tones. Perceptual organization strongly shapes listeners' memory for sounds, with implications for real-world communication.
