RESUMEN
Ganoderma lucidum (a mushroom used in traditional Chinese medicine) compounds may attenuate ageing-related physiological changes and restore normal immunity. However, studies on the physiological effects of Ganoderma lucidum dry extract food supplements are few. Therefore, here, we aimed to investigate the effects of Ganoderma lucidum dry extract food supplement on the lymphocyte function of older women. This was a double-blind clinical trial (n 60) with a final 39 older volunteers, divided into two groups Ganoderma lucidum (n 23) and placebo (n 16). The Ganoderma lucidum group received 2000 mg/d of Ganoderma lucidum dry extract for 8 weeks. We used flow cytometry to determine the lymphocyte profile. CD4+ lymphocyte gene expression was evaluated by real-time polymerase chain reaction. We observed that in the Ganoderma lucidum group, concanavalin A stimulation increased lymphocyte proliferation. Further, we observed an increase in expression of Forkhead box P3, transforming growth factor-beta, IL-10, IL-6, retinoic acid receptor-related orphan receptor gamma, GATA-binding protein 3 and interferon gamma genes in the Ganoderma lucidum group. Furthermore, in the Ganoderma lucidum group, ionomycin and phorbol 12-myristate 13-acetate stimulation led to decrease in Th17+ cells and increase in Th2+ cells. Thus, in older women, Ganoderma lucidum regulates T lymphocyte function leading to a predominant anti-inflammatory action but does not induce T lymphocyte proliferation through CD28 signalling pathway.
RESUMEN
OBJECTIVE: Most prior research on physical activity (PA) and cognition is based on predominantly white cohorts and focused on associations of PA with mean (average) cognition versus the distribution of cognition. Quantile regression offers a novel way to quantify how PA affects cognition across the entire distribution. METHODS: The Kaiser Healthy Aging and Diverse Life Experiences study includes 30% white, 19% black, 25% Asian, and 26% Latinx adults age 65+ living in Northern California (n = 1600). The frequency of light or heavy PA was summarized as 2 continuous variables. Outcomes were z-scored executive function, semantic memory, and verbal episodic memory. We tested associations of PA with mean cognition using linear regression and used quantile regression to estimate the association of PA with the 10th-90th percentiles of cognitive scores. RESULTS: Higher levels of PA were associated with higher mean semantic memory (b = 0.10; 95% CI: 0.06, 0.14) and executive function (b = 0.05; 95% CI: 0.01, 0.09). Associations of PA across all 3 cognitive domains were stronger at low quantiles of cognition. CONCLUSION: PA is associated with cognition in this racially/ethnically diverse sample and may have larger benefits for individuals with low cognitive scores, who are most vulnerable to dementia.

PURPOSE: Children with surgically corrected nonsyndromic craniosynostosis have been previously found to have neurocognitive and behavioral difficulties. Children with metopic synostosis have been described to have more difficulties than children with sagittal synostosis. This study aims to characterize the behavioral differences between children with metopic and sagittal synostosis. METHODS: Children with metopic and sagittal synostosis were recruited at school age. Parents completed four separated behavioral assessments: Conners-3 (evaluation of ADHD), Social Responsiveness Scale-2 (SRS-2: evaluation of autism), Behavior Rating Inventory of Executive Function-2 (BRIEF-2: evaluation of executive function), and Child Behavior Checklist (CBCL: evaluation of overall behavioral problems). Children underwent intelligence quotient (IQ) testing using the Wechsler Abbreviated Scale of Intelligence (WASI-II). RESULTS: There were 91 children (45 with metopic and 46 with sagittal synostosis). More children with metopic synostosis reported requiring supportive services (57.7% vs 34.7%, p = 0.02) and more reached or exceeded borderline clinical levels of two executive function subscales of the BRIEF-2 (emotion regulation index: 33.3% vs 17.4%, p = 0.05; global executive composite: 33.3% vs 17.4%, p = 0.05). Children with sagittal synostosis had higher scores on the rule-breaking and externalizing problem subscales of the CBCL. Increasing age at surgery was associated with worse executive function scores. CONCLUSIONS: A relationship between suture subtype and behavioral outcomes exists at school age. More children with metopic synostosis required social services indicating more overall difficulties. Children with metopic synostosis have more specific problems with executive function, while children with sagittal synostosis had more difficulties with externalizing behaviors.

BACKGROUND: Children with metopic synostosis have been found to have more neurocognitive and behavioral difficulties. The variables that may affect future neurodevelopmental outcomes, including presenting morphologic severity, have not been fully studied. In the largest study to date, we aimed to assess what portends worse neurocognitive and behavioral outcomes at school age. METHODS: Children 6-18 years old with surgically corrected metopic nonsyndromic craniosynostosis underwent neurocognitive testing. Parents completed behavior rating surveys about their child: Conners-3 (ADHD), Social Responsiveness Scale-2 (autism spectrum disorder), Behavior Rating Inventory of Executive Function-2 (BRIEF-2: executive function), and Child's Behavior Checklist (overall behavior). The endocranial bifrontal angle (EBA), adjusted EBA (aEBA), frontal angle (FA), and AI-derived metopic severity score (MSS) were determined on pre-operative CT images. Multivariate linear regressions were used to evaluate the association of age at surgery and severity. RESULTS: There were 87 children who underwent neurocognitive testing (average age 10.9 ± 3.3 years) of whom 67 also completed behavioral assessments. Greater phenotypical severity of metopic synostosis (lower FA, aEBA, and EBA) was associated with worse scores on the subscales of the BRIEF-2 (executive function) and executive subscale of the Conners-3. Increasing age at surgery was associated with worse executive function subscale scores of the Conners-3 when controlling for each severity measurement and sociodemographic risk. CONCLUSION: Children with greater phenotypic severity of metopic synostosis have worse executive function at school age. The majority of children with metopic synostosis have signs of ADHD. Later surgeries (greater than 12 months) may impact executive functioning, regardless of the degree of severity. Future research should aim at identifying the direct structural changes to the brain.
RESUMEN
PURPOSE: Nonsyndromic craniosynostosis (NSC) is associated with neurocognitive deficits, and intervention at infancy is standard of care to limit the negative effects of NSC on brain development. In this study, diffusion tensor imaging (DTI) was implemented to investigate white matter microstructure in infants with NSC undergoing cranial vault remodeling, and a comparison was made with white matter development in neurotypical controls. METHODS: Infants presenting with NSC (n = 12) underwent DTI scans before and after cranial vault remodeling. Neurotypical infants (n = 5), age matched to NSC patients at preoperative scans, were compared to preoperative DTI scans. Pre- and postoperative NSC scans were compared in aggregate, and the sagittal synostosis (n = 8) patients were evaluated separately. Finally, neurotypical infants from the University of North Carolina/University of New Mexico Baby Connectome Project (BCP), who underwent DTI scans at timepoints matching the NSC pre- and postoperative DTI scans, were analyzed (n = 9). Trends over the same time period were compared between NSC and BCP scans. RESULTS: No significant differences were found between preoperative NSC scans and controls. White matter development was more limited in NSC patients than in BCP patients, with microstructural parameters of the corpus body and genu and inferior and superior longitudinal fasciculi consistently lagging behind developmental changes observed in healthy patients. CONCLUSION: Infant white matter development appears more limited in NSC patients undergoing cranial vault remodeling relative to that in neurotypical controls. Further investigation is needed to explore these differences and the specific effects of early surgical intervention.

The potential use of carbon-based methodologies for drug delivery and reproductive biology in cows raises concerns about residues in milk and food safety. This study aimed to assess the potential of Fourier transform Raman spectroscopy and discriminant analysis using partial least squares (PLS-DA) to detect functionalized multiwalled carbon nanotubes (MWCNT) in bovine raw milk. Oxidized MWCNT were diluted in milk at different concentrations from 25.00 to 0.01 µg/mL. Raman spectroscopy measurements and PLS-DA were performed to identify low concentrations of MWCNT in milk samples. The PLS-DA model was characterized by the analysis of the variable importance in projection (VIP) scores. All the training samples were correctly classified by the model, resulting in no false-positive or false-negative classifications. For test samples, only one false-negative result was observed, for 0.01 µg/mL MWCNT dilution. The association between Raman spectroscopy and PLS-DA was able to identify MWCNT diluted in milk samples up to 0.1 µg/mL. The PLS-DA model was built and validated using a set of test samples and spectrally interpreted based on the highest VIP scores. This allowed the identification of the vibrational modes associated with the D and G bands of MWCNT, as well as the milk bands, which were the most important variables in this analysis.
RESUMEN
INTRODUCTION: With the recent transition to smooth tissue expanders (TEs), functional differences between TE subtypes have not been fully elucidated. This study evaluated the differences in TE characteristics and complications between 2 commonly used Mentor smooth TE models, Artoura and CPX4. METHODS: A retrospective review of patients who received either smooth Mentor Artoura or CPX4 TE from 2012 to 2022 was conducted. Demographic data, perioperative information, pain scores, TE variables, cancer characteristics, and complications were collected. A multivariate analysis was used to evaluate the relationship between TE subtype and complications while controlling for demographic, TE characteristics, radiation, and chemotherapy exposure. RESULTS: During the study period, 62 smooth Artoura TEs and 79 smooth CPX4 TEs were used. Patients who received CPX4 smooth implants tended to be older (51.09 vs 46.18 years old, P = 0.02) and have a higher body mass index (28.66 vs 23.50 kg/m 2 , P < 0.001). There were no differences among patient comorbidities. CPX4 required on average a greater total fill volume (422.23 vs 348.07 mL, P = 0.01) and had a greater drain duration (16.91 vs 14.33 days, P = 0.05). There were no differences in TE plane placement between Artoura and CPX4. Additionally, there were no differences in complication rates, including infection, hematomas, seromas, wound breakdown, TE replacement, and capsular contracture. When controlling for body mass index, diabetes, TE plane placement, acellular dermal matrix use, radiation exposure, and chemotherapy, there was no association between TE subtype and any individual complication. DISCUSSION: Differences in total fill volume and drain duration were significantly different between Mentor Artoura and CPX4 implants, which may influence TE subtype selection. However, Artoura and CPX4 have excellent and equivalent safety profiles with similar complication rates, even when controlling for demographic and TE characteristics.

Facial feminization surgery (FFS) is a type of gender-affirming surgery aimed at bringing masculine facial features more in line with typically feminine characteristics. Specifically, mandibular contouring can create a softer jawline and help create a more round, feminine face. As the popularity of FFS continues to increase, improving surgical techniques and patient satisfaction is imperative. However, no quantitative measurement system currently exists to measure these changes. In this study, the authors describe the use of a novel segmentation technique using computerized tomography imaging to quantify the bony changes that occur during gonial angle reduction. Further, authors utilize this technique to describe changes in a cohort of 13 patients, and how these changes correlate with patient satisfaction. The authors found that gonial angle volume and surface area significantly decreased, as well as the intergonial:interzygomatic ratio, with a smaller ratio associated with more feminine features. In addition, patient satisfaction significantly increased post-operatively both specifically regarding jawline appearance (P = 0.0014) and regarding overall social and psychological function (P = 0.0021 and P = 0.0032, respectively), as captured by the FACE-Q and World Health Organization Quality of Life (WHOQOL) surveys. Patients with greater changes in surface area reported greater improvements in WHOQOL psychological scores (P = 0.0086), and patients with greater changes in the intergonial:interzygomatic ratio reported greater improvements in WHOQOL social scores (P = 0.0299). Overall, our novel technique captures significant changes in gonial angle shape and can be applied to a wide range of future studies to improve the quality and accessibility of FFS.
RESUMEN
Measures of success for facial feminization surgery (FFS) have previously included improved rates of external gender perception as female and patient-reported outcome measures. In this study, we used artificial intelligence facial recognition software to objectively evaluate the effects of FFS on both perceived gender and age among male-to-female transgender patients, as well as their relationship with patient facial satisfaction. Standardized frontal preoperative and postoperative images of 27 transgender women undergoing FFS were analyzed by Amazon's AI facial recognition software to determine gender, femininity confidence score, and perceived age. Female gender-typing, improvement in gender-typing (preoperatively to postoperatively), and femininity confidence scores were analyzed. To assess patient satisfaction, FACE-Q modules were completed postoperatively. Preoperatively, FFS images were perceived as female 48.1% of the time, and postoperatively, this improved to 74.1% ( P =0.05). Femininity confidence scores improved from a mean score of 0.04 preoperatively to 0.39 postoperatively ( P =0.003). FFS was associated with a decrease in perceived age relative to the patient's true age (-2.4 y, P <0.001), with older patients experiencing greater reductions. Pearson correlation matrix found no significant relationship between improved female gender typing and patient facial satisfaction. Undergoing surgery at a younger age was associated with higher overall facial satisfaction ( r =-0.6, P =0.01). Transfeminine patients experienced improvements in satisfaction with facial appearance, perceived gender, and decreases in perceived age following FFS. Notably, patient satisfaction was not directly associated with improved AI-gender typing, suggesting that other factors may influence patient satisfaction.

Chronic kidney disease (CKD) presents a formidable global health concern, affecting one in six adults over 25. This review explores the potential of phenolic compounds in managing CKD and its complications. By examining the existing research, we highlight their diverse biological activities and potential to combat CKD-related issues. We analyze the nutritional benefits, bioavailability, and safety profile of these compounds. While the clinical evidence is promising, preclinical studies offer valuable insights into underlying mechanisms, optimal dosages, and potential side effects. Further research is crucial to validate the therapeutic efficacy of phenolic compounds for CKD. We advocate for continued exploration of their innovative applications in food, pharmaceuticals, and nutraceuticals. This review aims to catalyze the scientific community's efforts to leverage phenolic compounds against CKD-related challenges.

Surface-enhanced Raman spectroscopy (SERS) has gained increasing attention because it provides rich chemical information and high sensitivity, being applicable in many scientific fields including medical diagnosis, forensic analysis, food control, and microbiology. Although SERS is often limited by the lack of selectivity in the analysis of samples with complex matrices, the use of multivariate statistics and mathematical tools has been demonstrated to be an efficient strategy to circumvent this issue. Importantly, since the rapid development of artificial intelligence has been promoting the implementation of a wide variety of advanced multivariate methods in SERS, a discussion about the extent of their synergy and possible standardization becomes necessary. This critical review comprises the principles, advantages, and limitations of coupling SERS with chemometrics and machine learning for both qualitative and quantitative analytical applications. Recent advances and trends in combining SERS with uncommonly used but powerful data analysis tools are also discussed. Finally, a section on benchmarking and tips for selecting the suitable chemometric/machine learning method is included. We believe this will help to move SERS from an alternative detection strategy to a general analytical technique for real-life applications.

OBJECTIVE: To propose a short version of the lower extremity functional scale (LEFS), to compare our short version with the different structures proposed for the LEFS by the specialized literature, and to verify the criterion validity of the best structure of the LEFS identified in our study. DESIGN: Cross-sectional observational study. SETTING: Physiotherapy clinics. PARTICIPANTS: We included 140 patients with lower limb dysfunction (N=140). INTERVENTIONS: None. MAIN OUTCOME MEASURES: We used confirmatory factor analysis (CFA), χ2/degree of freedom (DF), comparative fit index (CFI), Tucker-Lewis index (TLI), root mean square error of approximation (RMSEA), standardized root mean squared residual (SRMR), Akaike information criterion (AIC), and Bayesian information criterion (BIC). The method of reducing the number of items of the LEFS considered the modification indices and factor loadings. RESULTS: The body site most affected by pain was the knee (71.4%), and the most common diagnoses were knee osteoarthritis (55%) and anterior knee pain (11.4%). LEFS reduction generated a 1-dimensional structure of the LEFS with 10 items (LEFS-10). When compared with other structures, the LEFS-10 presented the best fit indices (χ2/DF=1.88, CFI=0.975, TLI=0.968, RMSEA=0.079, and SRMR=0.058) and the lowest values of AIC (3287.063) and BIC (3345.896). LEFS-10 presents a high correlation (Spearman's correlation coefficient [ρ]=0.911, P<.001) with the 20-item LEFS. CONCLUSION: LEFS-10 is the proposal for a short version of the instrument with the most adequate internal structure, in addition to being satisfactorily correlated with the longer version of the instrument.

PURPOSE: Craniosynostosis, which describes premature fusion of one or more cranial sutures, has been associated with a variety of neurocognitive deficits. We sought to explore the cognitive profiles of the various types of single-suture, non-syndromic craniosynostosis (NSC). METHODS: A retrospective review of children 6-18 years old with surgically corrected NSC who underwent neurocognitive testing (Weschler Abbreviated Scale of Intelligence, Beery-Buktenica Developmental Test of Visuomotor Integration) from the years 2014-2022 was conducted. RESULTS: 204 patients completed neurocognitive testing (139 sagittal, 39 metopic, 22 unicoronal, 4 lambdoid suture). 110 (54%) of the cohort was male, and 150 (74%) were White. Mean IQ was 106.10±14.01 and mean age at surgery and testing were 9.0±12.2 months and 10.9±4.0 years, respectively. Sagittal synostosis was associated with higher scores than metopic synostosis, with significant differences in verbal IQ (109.42±15.76 vs 101.37±10.41), full-scale IQ (108.32±14.44 vs 100.05±11.76), visuomotor integration (101.62±13.64 vs 92.44±12.07), visual perception (103.81±12.42 vs 95.87±11.23), and motor coordination (90.45±15.60 vs 84.21±15.44). Sagittal synostosis was associated with significantly higher scores for visuomotor integration (101.62±13.64 vs 94.95±10.24) and visual perception (103.81±12.42 vs 94.82±12.75) than unicoronal synostosis. CONCLUSIONS: Compared to patients with sagittal synostosis, patients with metopic synostosis exhibited lower scores in verbal IQ, full-scale IQ, visuomotor integration, visual perception, and motor control after surgical correction. Despite surgical correction for premature metopic suture fusion, the effect on the adjacent frontal lobe and white matter connections to other regions of the brain may have a lasting functional impact. Patients with unicoronal synostosis exhibited lower visuomotor integration and visual perception scores.

Arthropods, the largest animal phylum, including insects, spiders and crustaceans, are characterized by their bodies being covered primarily in chitin. Besides being a source of this biopolymer, crustaceans have also attracted attention from biotechnology given their cuticles' remarkable and diverse mechanical properties. The goose barnacle, Pollicipes pollicipes, is a sessile crustacean characterized by their body parts covered with calcified plates and a peduncle attached to a substrate covered with a cuticle. In this work, the composition and structure of these plates and cuticle were characterized. The morphology of the tergum plate revealed a compact homogeneous structure of calcium carbonate, a typical composition among marine invertebrate hard structures. The cuticle consisted of an outer zone covered with scales and an inner homogenous zone, predominantly organic, composed of successive layers parallel to the surface. The scales are similar to the tergum plate and are arranged in parallel and oriented semi-vertically. Structural and biochemical characterization confirmed a bulk composition of É-chitin and suggested the presence of elastin-based proteins and collagen. The mechanical properties of the cuticle showed that the stiffness values are within the range of values described in elastomers and soft crustacean cuticles resulting from molting. The removal of calcified components exposed round holes, detailed the structure of the lamina, and changed the protein properties, increasing the rigidity of the material. This flexible cuticle, predominantly inorganic, can provide bioinspiration for developing biocompatible and mechanically suitable biomaterials for diverse applications, including in tissue engineering approaches.

BACKGROUND: Facial feminization surgery (FFS) consists of multiple, complex procedures. Well-informed patients have been shown to have better outcomes and expectations. However, there is limited data evaluating FFS patient-oriented material online. This study aims to evaluate the quality and readability of FFS literature online. METHODS: Facial feminization surgery-related terms were queried in Google with location, cookies, and user account information disabled. Websites were analyzed for readability using Flesch Reading Ease and Flesch-Kincaid Reading Grade Level, suitability using the suitability assessment of materials (SAM), and quality using the DISCERN scale. Unpaired t tests and χ2 tests were used to compare the websites of community-based and academic or public institutions. RESULTS: One hundred twenty websites met inclusion criteria (71 community-based and 49 academic). The average reading grade level was 11.68 ± 1.71. The average SAM score was 53.11 ± 11.75, denoting adequate readability. Only 16.67% of websites contained visual aids to assist in explaining procedures and benefits. Overall, 68.33% of websites' DISCERN score was rated very poor or poor, whereas only 8.33% were rated as good. The following DISCERN elements had the lowest scores across all graded websites: "clear source and date of information," "details of additional source of support," "refers to areas of uncertainty," and "describes risks of each treatment." Websites published by community-based institutions were significantly better in describing how FFS works and the benefits of each procedure. Academic sites overall were less biased (4.84 vs 4.62, P = 0.03) and provided additional sources of support (2.35 vs 1.32, P = <0.001). CONCLUSIONS: Online FFS patient resources should be written at a more inclusive reading level and should increase the use of pictorial aids to improve patient comprehension. Facial feminization surgery patient resources were significantly above the recommended sixth grade reading level for health literature. Academic and community-based institutions should include more information about procedural risks and limitations in surgical outcomes to ensure a broader scope of understanding.

Accelerated in part by the coronavirus disease 2019 pandemic, medical education has increasingly moved into the virtual sphere in recent years. Virtual surgical education encompasses several domains, including live virtual surgery and virtual and augmented reality. These technologies range in complexity from streaming audio and video of surgeries in real-time to fully immersive virtual simulations of surgery. This article reviews the current use of virtual surgical education and its possible applications in hand surgery. Applications of virtual technologies for preoperative planning and intraoperative guidance, as well as care in underresourced settings, are discussed. The authors describe their experience creating a virtual surgery subinternship with live virtual surgeries. There are many roles virtual technology can have in surgery, and this review explores potential value these technologies may have in hand surgery.

Microtia can have deleterious impacts on the functional, psychological, and aesthetic outcomes of affected young children. Reconstructive procedures can alleviate these negative outcomes and significantly improve the quality of life for patients; however, the cost and length of hospital stay (LOS) for such procedures and the factors that impact them have not been well-characterized. This study seeks to understand the hospital-level (institution type, size, and geographic region) and patient-level factors (race, age, and insurance status) that impact cost and LOS in patients who undergo microtia reconstructive surgery. A retrospective data analysis was conducted utilizing the National Inpatient Sample (NIS) database for the years 2008 to 2015. Inclusion criteria included patients who had an International Classification of Diseases, Ninth Revision (ICD-9) diagnostic code for microtia (744.23) as well as a procedure for microtia correction (186×/187×). A total of 714 microtia repair cases met the inclusion criteria and were sampled from the NIS database. Microtia repair cost was significantly increased on the West Coast compared with the Northeast ($34,947 versus $29,222, P =0.020), increased with patient age ($614/y, P =0.012), and gradually increased from 2008 to 2015 ($25,897-$48,985, P <0.001). Microtia LOS was significantly increased with government-controlled hospitals compared with private hospitals (1.93 versus 1.39 d, P =0.005), increased with patients on Medicaid compared with private insurance (2.33 versus 2.00 d, P =0.036), and overall decreased with patient age (-0.07 d/y, P =0.001). The results not only identify the multifactorial impacts that drive cost and LOS in microtia repair but provide insights into the financial and medical considerations patients and their families must navigate.

Cranial vault remodeling (CVR) with and without frontal orbital advancement remodels the skull in craniosynostosis. Virtual surgical planning (VSP) for preoperative planning has been previously shown to be effective in CVR. In this study, the authors aimed to evaluate the impact of VSP on operative and perioperative efficiency for craniosynostosis surgery. A retrospective chart review was conducted of patients with craniosynostosis who underwent CVR. Patient demographics, perioperative variables, use of VSP, and complications were obtained. Perioperative variables collected include operative time and length of stay. An independent t test was used to compare variables from patients who had surgery with VSP and patients who did not. Records were available for 126 patients with craniosynostosis who underwent CVR of whom 79 (62.7%) utilized VSP. There was no difference in average age at surgery (9.3±5.7 mo versus 13.2±31.1 mo, P =0.39). Surgeries planned using VSP demonstrated a decreased operative time of 1.3 hours (3.7±1.1 versus 5.0±1.1 h, P <0.001) and a shorter length of stay (3.9±1.3 versus 4.6±1.7 d, P =0.01). There were no differences in complication rates of dehiscence, infection, returns to the operating room, or 30-day readmission. These trends were similar among patients who underwent fronto-orbital advancement in addition to CVR. Virtual surgical planning was associated with decreased operative time and length of stay for patients with craniosynostosis and comparable complication rates. Virtual surgical planning is an effective tool for reducing anesthetic exposure time.
