Decoding the Mastectomy SKIN Score: An Evaluation of Its Predictive Performance in Immediate Breast Reconstruction.

BACKGROUND: The skin ischemia and necrosis (SKIN) score was introduced to standardize the assessment of mastectomy skin flap necrosis (MSFN) severity and the need for reoperation. The authors evaluated the association between the SKIN score and the long-term postoperative outcomes of MSFN after mastectomy and immediate breast reconstruction. METHODS: The authors conducted a retrospective cohort study of consecutive patients who developed MSFN after mastectomy and immediate breast reconstruction from January of 2001 to January of 2021. The primary outcome was breast-related complications after MSFN. Secondary outcomes were 30-day readmission, operating room (OR) débridement, and reoperation. Study outcomes were correlated with the SKIN composite score. RESULTS: The authors identified 299 reconstructions in 273 consecutive patients with mean follow-up time of 111.8 ± 3.9 months. Most patients had a composite SKIN score of B2 (25.0%, n = 13), followed by D2 (17.3%) and C2 (15.4%). We found no significant difference in rates of OR débridement ( P = 0.347), 30-day readmission ( P = 0.167), any complication ( P = 0.492), or reoperation for a complication ( P = 0.189) based on the SKIN composite score. The composite skin score was a poor predictor of reoperation, with an area under the curve of 0.56. A subgroup analysis in patients who underwent implant-based reconstruction revealed no difference in rates of OR débridement ( P = 0.986), 30-day readmission ( P = 0.530), any complication ( P = 0.492), or reoperation for a complication ( P = 0.655) based on the SKIN composite score. CONCLUSIONS: The SKIN score was a poor predictor for postoperative MSFN outcomes and reoperation. An individualized risk-assessment tool that incorporates the anatomic appearance of the breast, imaging data, and patient-level risk factors is needed. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, IV.

Effective sludge management: Reuse of biowaste and sewer sediments for fired bricks.

This study partially replaced the clay with sewer sludge (SS) and rice husk (RH-SS) to make fired bricks. The brick samples were examed in terms of shrinkage, water absorption, and compressive strength. Besides, they were analyzed via XRD and metal extraction to determine the heavy metal residuals in the products. The results showed that it was possible to fabricate fired bricks using sewer sludge or rice husk-blended sludge with up to 30% by weight. These brick samples complied with the technical standard for clay brick production, in which the compressive strength was more than 7.5 MPa, water absorption was from 11-16%, and the linear shrinkage was all less than 5%. The rice husk addition helped mitigate the heavy metal residuals in the bricks and leaching liquid, in which all the values were lower than the US-EPA maximum concentration of contaminants for toxicity characteristics.Implications: Previous studies have proved the possibility of mixing sewage sludge from different origins (sewage sludge, river sediment, canal sediment, sewer sediment, etc.) with clay and some wastes to make bricks. In which, mostof the studies used sewage sludge from wastewater treatment plants, very fewdealt with lake/river or sewer sediment. This study shall be the first to study the possibility of employing sewer sediments with the addition of rice husk powder to achieve two targets, including (1) the reuse of biowaste and sludge for brick fabrication and (2) the reduction of heavy metals in final calcined bricks. Different ratios of the rice-husk blended sewer sludge (RH-SS) - clay mixture shall be tested to find the optimized compositions. The results showed that it was possible to fabricate fired bricks using sewer sludge or rice husk-blended sludge with up to 30% by weight, which meant reduce 30% of clay in the brick production. The final products were proved to meet the quality standard in terms of compressive strength (more than 10 MPa), water absorption(from 11-16%), and the linear shrinkage (less than 5%). Larger scale of this study can be an evident to recommend for policy change in the waste reuse in construction field.

Artificial Intelligence Methods for the Argenta Classification of Deformational Plagiocephaly to Predict Severity and Treatment Recommendation.

INTRODUCTION: Deformational plagiocephaly (DP) can be classified into 5 severity types using the Argenta scale (AS). Patients with type III or higher require referral to craniofacial surgery for management. Primary care pediatricians (PCPs) are often the first to encounter patients with DP, but current screening methods are subjective, increasing the risk of bias, especially for clinicians with little exposure to this population. The authors propose the use of artificial intelligence (AI) to classify patients with DP using the AS and to make recommendations for referral to craniofacial surgery. METHODS: Vertex photographs were obtained for patients diagnosed with unilateral DP from 2019 to 2020. Using the photographs, an AI program was created to characterize the head contour of these infants into 3 groups based on the AS. The program was trained using photographs from patients whose DP severity was confirmed clinically by craniofacial surgeons. To assess the accuracy of the software, the AS predicted by the program was compared with the clinical diagnosis. RESULTS: Nineteen patients were assessed by the AI software. All 3 patients with type I DP were correctly classified by the program (100%). In addition, 4 patients with type II were correctly identified (67%), and 7 were correctly classified as type III or greater (70%). CONCLUSIONS: Using vertex photographs and AI, the authors were able to objectively classify patients with DP based on the AS. If converted into a smartphone application, the program could be helpful to PCPs in remote or low-resource settings, allowing them to objectively determine which patients require referral to craniofacial surgery.

Fried Frailty Phenotype in Elderly Patients with Chronic Coronary Syndrome: Prevalence, Associated Factors, and Impact on Hospitalization.

Purpose: To investigate the prevalence and factors associated with frailty and impact of frailty on hospitalization due to any cause in elderly patients with chronic coronary syndrome (CCS). Patients and Methods: We conducted a study wherein we assessed frailty using Fried frailty phenotype for outpatients aged ≥60 years with CCS. Logistic regression analysis was performed to assess the factors associated with frailty. Frailty was adjusted for demographic and geriatric variables and comorbidities to assess its impact on hospitalization. Results: Overall, 420 patients (median age 70 years [interquartile range, 65-77]; men, 74.5%) who completed the 3-month follow-up period were analyzed. Coronary revascularization for > 1 year was the most common clinical scenario for CCS (59.8%; n = 251). The prevalence of non-frail, pre-frail, and frail patients were 22.4% (n = 94), 49.7% (n = 209), and 27.9% (n = 117), respectively. In the adjusted model, three factors associated with frailty were age ≥ 75 years (odds ratio [OR] 2.29, 95% confidence interval [CI] 1.39-3.75, P = 0.001), limitations in instrumental activity of daily living (OR 3.89, 95% CI 2.33-6.48, P < 0.001), and heart failure (OR 2.30, 95% CI 1.32-4.02, P = 0.003). The overall 3-month hospitalization rate was higher in frail patients than in non-frail patients (23.9% vs 13.5%, P = 0.012). Frailty was associated with hospitalization (OR 1.85, 95% CI 1.04-3.30, P = 0.037) but in a weak strength of association (r = 0.126). Conclusion: The prevalence of frailty was 27.9% in the elderly patients with CCS. Age ≥ 75 years, limitations in functional status, and heart failure were associated with increased odds of frailty. Frailty was a predictor of 3-month all-cause hospitalization in these patients.

What is the significance of the chloroform stabilizer C5H10 and its association with MeOH in concentration-dependent polymeric solutions?

The understanding of excitonic transitions associated with polymeric aggregates is fundamental, as such transitions have implications on coherence lengths, coherence numbers and inter- and intra-chain binding parameters. In this context, the investigation of efficient solvents and other ways to control polymer aggregate formation is key for their consolidation as materials for new technologies. In this manuscript, we use Poly(3-hexothiophene) (P3HT) as a probe to investigate the significance of amylene (C5H10) and its association with methanol (MeOH) in both pure and C5H10-stabilized chloroform (CHCl3)-based polymeric solutions. Using the intensity ratio between the first and second vibronic transitions of the P3HT H-aggregates formed, values for their exciton bandwidths and interchain interactions are obtained and correlated with the presence of C5H10 and MeOH as agents determining the CHCl3 quality.

Implementation of Mandibular Distraction Osteogenesis for Patients With Pierre Robin Sequence in a Developing Country Through International Collaboration: A Paradigm for Success.

OBJECTIVE: Though it has made significant strides, Vietnam remains a resource-constrained country of 98 million people. Vietnam National Children's Hospital (VNCH) provides tertiary care to a catchment of 40 million people and is the sole national children's hospital. As such, it is one of the few referral centers in the country equipped to take care of patients diagnosed with Pierre Robin sequence (PRS) as this requires pulmonary, critical care, otolaryngology, and plastic surgery expertise. Before 2015, the only surgical options were tongue lip adhesion or tracheostomy. Only 20% of patients successfully avoided tracheostomy, mechanical ventilation, or death. From 2015 to 2019, mandibular distraction osteogenesis (MDO) was introduced by visiting international surgeons on a short-term basis. Since 2020, local surgeons at VNCH have refined their technique and widely use MDO independently. This report seeks to capitulate their experience and identify factors leading to success. METHODS: A retrospective review was conducted of patients diagnosed with PRS at VNCH from 2015 to 2022. Paper records were digitized, translated, and reviewed for inclusion criteria, including demographics, indications, hospital course, and postoperative outcomes. RESULTS: Complete records satisfying inclusion criteria were available for 53 patients with a diagnosis of PRS who underwent MDO from 2020 to 2022. From 2015 to 2019, there were 19 cases of MDO, though records were incomplete. The median age at the time of MDO was 50 ± 43 days. Forty patients (75.5%) had isolated PRS and 13 (24.5%) were syndromic. Forty-four patients (83%) had a cleft palate. Fifty-one (96.2%) of patients required preoperative supplemental oxygen or mechanical ventilation. The active distraction and consolidation phase was 4.8 ± 1.3 months. The median days to discharge after surgery was 19.0 ± 8.3 days. Median weight at birth, at the time of surgery, and at the time of device removal were 6.8 ± 1.2, 7.7 ± 1.9, and 14.8 ± 2.8 pounds, respectively. Fifty-two patients (98.1%) had obstructive sleep apnea preoperatively with an average Apnea Hypopnea Index of 25.0 ± 10.6. Post-MDO, only 4 (7.5%) had obstructive sleep apnea and the average Apnea Hypopnea Index was 5.2 ± 0.6. No patients (0) required a tracheostomy for a 100% success rate. CONCLUSIONS: The tremendous success of the implementation of MDO by local surgeons in Vietnam after its introduction by visiting international surgeons illustrates a paradigm for capacity-enhancing global surgical endeavors. Mandibular distraction osteogenesis has replaced tongue lip adhesion as the surgical treatment of choice for PRS patients at VNCH. Surgical techniques can be transferred to operating environments with basic infrastructure through collaboration and resource optimization. These results demonstrate that global surgical engagement may be scalable and repeatable with direct benefits for patients in lower-middle-income countries.

Evaluation of Helmeting Therapy Duration After Endoscopic Strip Craniectomy for Metopic and Sagittal Craniosynostosis.

INTRODUCTION: Endoscopic strip craniectomy (ESC) is a minimally invasive option for early surgical treatment of metopic (MC) and sagittal craniosynostosis (SC). For ESC, however, the postoperative duration and compliance of helmet therapy are crucial to correct MC and SC asymmetry. The purpose of this study is to assess the period of postoperative band therapy and determine differences, if any, between MC and SC. METHODS: A single-institution retrospective review was performed for patients with MC and SC who underwent ESC from November 2015 to 2019. Patients received preoperative, postoperative, and post-band 3-dimensional imaging. Factors recorded included patient sex, insurance type, number of helmets needed, age at surgery, time of first helmet, and at time of completion of helmet therapy, cephalic index, interfrontal angle, and cranial vault asymmetry index. RESULTS: Patients with SC and MC had ESC surgery at 3.3 and 3.4 months of age, respectively.Patients with SC were found to have completed banding therapy at a younger age (7.88 versus 10.0 mo), with shorter duration (4.17 versus 6.00 mo), and less number of bands (1.54 versus 2.21) than patients with MC. After regression analysis, suture type was found to be a significant predictor of total time in band therapy (P=0.039) with MC requiring a longer duration of banding therapy when compared with SC. CONCLUSIONS: Suture type directly correlates with duration of helmeting therapy for patients, with patients with MC requiring longer periods of postop helmeting and increased number of bands as compared with SC.

Nitric Oxide-Induced Morphological Changes to Bacteria.

Antimicrobial resistance poses a serious threat to global health, necessitating research for alternative approaches to treating infections. Nitric oxide (NO) is an endogenously produced molecule involved in multiple physiological processes, including the response to pathogens. Herein, we employed microscopy- and fluorescence-based techniques to investigate the effects of NO delivered from exogenous NO donors on the bacterial cell envelopes of pathogens, including resistant strains. Our goal was to assess the role of NO donor architecture (small molecules, oligosaccharides, dendrimers) on bacterial wall degradation to representative Gram-negative bacteria (Klebsiella pneumoniae, Pseudomonas aeruginosa) and Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecium) upon treatment. Depending on the NO donor, bactericidal NO doses spanned 1.5-5.5 mM (total NO released). Transmission electron microscopy of bacteria following NO exposure indicated extensive membrane damage to Gram-negative bacteria with warping of the cellular shape and disruption of the cell wall. Among the small-molecule NO donors, those providing a more extended release (t1/2 = 120 min) resulted in greater damage to Gram-negative bacteria. In contrast, rapid NO release (t1/2 = 24 min) altered neither the morphology nor the roughness of these bacteria. For Gram-positive bacteria, NO treatments did not result in any drastic change to cellular shape or membrane integrity, despite permeation of the cell wall as measured by depolarization assays. The use of positively charged quaternary ammonium (QA)-modified NO-releasing dendrimer proved to be the only NO donor system capable of penetrating the thick peptidoglycan layer of Gram-positive bacteria.

Biofilm Dispersal, Reduced Viscoelasticity, and Antibiotic Sensitization via Nitric Oxide-Releasing Biopolymers.

Compared to planktonic bacteria, biofilms are notoriously difficult to eradicate due to their inherent protection against the immune response and antimicrobial agents. Inducing biofilm dispersal to improve susceptibility to antibiotics is an attractive therapeutic avenue for eradicating biofilms. Nitric oxide (NO), an endogenous antibacterial agent, has previously been shown to induce biofilm dispersal, but with limited understanding of the effects of NO-release properties. Herein, the antibiofilm effects of five promising NO-releasing biopolymer candidates were studied by assessing dispersal, changes in biofilm viscoelasticity, and increased sensitization to tobramycin after treatment with NO. A threshold level of NO was needed to achieve biofilm dispersal, with longer-releasing systems requiring lower concentrations. The most positively charged NO-release systems (from the presence of primary amines) led to the greatest reduction in viscoelasticity of Pseudomonas aeruginosa biofilms. Co-treatment of tobramycin with the NO-releasing biopolymer greatly decreased the dose of tobramycin required to eradicate tobramycin-susceptible and -resistant biofilms in both cellular and tissue models.

Assessment of fluctuations in wetland ecosystem areas resulting from anthropogenic activities in the Dong Rui commune, Quang Ninh Province, Vietnam.

Wetlands are one of the most important ecosystems as habitats for many animal and plant species and are crucial for disaster mitigation, improving environmental quality, storing carbon, and responding to climate change. However, these sensitive ecosystems have been heavily affected by anthropogenic activities, including aquaculture. In this study, we used multitemporal satellite imagery integrated with a verified field survey method to map the coverage of the wetland ecosystem in the Dong Rui commune, Tien Yen district, Quang Ninh Province, Vietnam, five times for four periods from 1975 to 2022, with high accuracy (overall accuracy = 92.3%, Kappa = 0.91). The results showed that from 1975 to 2000, the area of mangrove forests declined sharply (by nearly 2,000 ha), mainly due to policies of development and conversion of land use. From 2000 to 2022, the mangrove forest area was gradually restored, while the area under aquaculture shrank. Anthropogenic impacts, especially the effects of local economic development, and conservation and developmental policies, are the main causes of continuous change in each short period. Our study demonstrates satellite imagery as an effective tool for assessing wetland ecosystem area fluctuations and assessing the extent of human impacts on this natural ecosystem. Our findings can serve as a basis for planning, conservation strategies, and sustainable development of wetland ecosystems and for improving the associated livelihoods of the communities.

The Skin Necrosis Conundrum: Examining Long-term Outcomes and Risk Factors in Implant-Based Breast Reconstruction.

BACKGROUND: Mastectomy skin flap necrosis (MSFN) is a common complication following mastectomy that causes significant distress to patients and physicians and also compromises oncologic, surgical, and quality-of-life outcomes. OBJECTIVES: We sought to investigate the long-term outcomes of MSFN following implant-based reconstruction (IBR) and determine the rates and predictors of post-MSFN complications. METHODS: This was a 20-year analysis of consecutive adult (>18 years) patients who developed MSFN following mastectomy and IBR from January 2001 to January 2021. Multivariable analyses were performed to identify factors associated with post-MSFN complications. RESULTS: We identified 148 reconstructions, with a mean follow-up time of 86.6 ± 52.9 months. The mean time from reconstruction to MSFN was 13.3 ± 10.4 days, and most cases (n = 84, 56.8%) were full-thickness injuries. Most cases (63.5%) were severe, 14.9% were moderate, and 21.6% were mild. Forty-six percent (n = 68) developed a breast-related complication, with infection being the most common (24%). An independent predictor of overall complications was longer time from reconstruction to MSFN (odds ratio [OR], 1.66; P = .040). Aging was an independent predictor of overall complications (OR, 1.86; P = .038); infection (OR, 1.72; P = .005); and dehiscence (OR, 6.18; P = .037). Independent predictors of dehiscence were longer interval from reconstruction to MSFN (OR, 3.23; P = .018) and larger expander/implant size (OR, 1.49; P = .024). Independent predictors of explantation were larger expander/implant size (OR, 1.20; P = .006) and nipple-sparing mastectomy (OR, 5.61; P = .005). CONCLUSIONS: MSFN is associated with high risk of complications following IBR. Awareness of the timing and severity of MSFN and the predictors of post-MSFN complications is crucial for guiding evidence-based decision-making and improving outcomes.

Effect of biowaste and construction waste additives on mechanical dewaterability of lake sediment for brick production.

Nowadays, when the zero-waste strategy is an inevitable component of the circular economy, the reuse of waste, including dredged sludges, has drawn the attention of many researchers. This study evaluated four kinds of bio-wastes (corn core powder, rice husk powder, sugarcane bagasse powder, and peanut shell powders) and two kinds of construction wastes (autoclaved aerated concrete-AAC and pavement stone) in enhancing the dewaterability of dredged sludge from the lake, in which the sludges would then be reused for brick production. The results showed that the moisture contents decreased from 62 ± 0.14% to 57 ± 1.89% after mixing and then to 35 ± 8.31% after compressing for the construction waste-blended sludge. Among the bio-wastes, the sugarcane bagasse additive performed the best at a mixing ratio of 1:3 by weight and rice husk powder worked best at a mixing ratio of 1:5 by weight. The organic matter was increased up to 80% when the bio-wastes were added, while it was decreased to 5% for the case of construction wastes. The optimum percentage of sludge in the mixture to meet all the oxide contents in the brick and energy saving shall be about 30%. The results have revealed a potentially green route for brick production with lake sediment and bio-waste/construction wastes.Implications: It is the first time the reuse of agro-wastes/construction waste was evaluated to mix with lake sediment to partly replace clay for brick production; Among the bio-wastes, the sugarcane bagasse additive performed the best at a mixing ratio of 1:3 by weight; Moisture contents decreased from 62 ± 0.14% to 57 ± 1.89% after mixing and then to 35 ± 8.31% after compressing for the blended sludge; The optimum percentage of mixed sludge, possibly replaced the clay in brick production, considering oxide contents and energy saving shall be up to 30%.

Decoding the Mastectomy SKIN Score: An Evaluation of Its Predictive Performance in Immediate Breast Reconstruction.

BACKGROUND: The skin ischemia and necrosis (SKIN) score was introduced to standardize the assessment of mastectomy skin flap necrosis (MSFN) severity and the need for reoperation. We evaluated the association between the SKIN score and the long-term postoperative outcomes of MSFN after mastectomy and immediate breast reconstruction (IBR). METHODS: We conducted a retrospective cohort study of consecutive patients who developed MSFN following mastectomy and IBR from January 2001 to January 2021. Primary outcome was breast-related complications following MSFN. Secondary outcomes were 30-day readmission, operating room (OR) debridement, and reoperation. Study outcomes were correlated with the SKIN composite score. RESULTS: We identified 299 reconstructions in 273 consecutive patients with mean follow-up time of 111.8±3.9 months. Most patients had a composite SKIN score of B2 (25.0%, n=13), followed by D2 (17.3%) and C2 (15.4%). We found no significant difference in rates of OR debridement (p=0.347), 30-day readmission (p=0.167), any complication (p=0.492), or reoperation for a complication (p=0.189) based on the SKIN composite score. The composite skin score was a poor predictor of reoperation, with area under the curve (AUC) of 0.56. A subgroup analysis in patients who underwent implant-based reconstruction revealed no difference in rates of OR debridement (p=0.986), 30-day readmission (p=0.530), any complication (p=0.492), or reoperation for a complication (p=0.655) based on the SKIN composite score. CONCLUSION: The SKIN score was a poor predictor for postoperative MSFN outcomes and reoperation. An individualized risk-assessment tool that incorporates both the anatomical appearance of the breast, imaging data, and patient-level risk factors is needed.

COVID-19 infection and decline in outdoor activities associated with depression in older adults: A multicenter study in Vietnam.

BACKGROUND: The coronavirus disease (COVID-19) pandemic has caused a serious global communicable disease burden. Although COVID-19 and its policy responses have significantly influenced older adults, the impact of COVID-19 on depression in the older population is not fully understood. We aimed to investigate whether a history of COVID-19 infection and a decline in outdoor activities during the COVID-19 pandemic were associated with depression among older adults in Vietnam. METHODS: This multicenter cross-sectional study was conducted on 1,004 outpatients (aged ≥60 years; mean age 70.8 ± 7.3 years; men, 33.0%) visiting three hospitals for a comprehensive geriatric assessment between November 2021 and July 2022. Depression over the past week was evaluated using the 15-item Geriatric Depression Scale. History of COVID-19 infection and decline in outdoor activities were included as binary variables. We adjusted these two factors with sociodemographic and geriatric variables and comorbidities using a logistic regression analysis in separate models. RESULTS: A total of 156 participants (15.5%) experienced depression. The proportion of mild, moderate, and severe depressive symptoms was 14.1%, 44.9%, and 41.0%, respectively. In the multivariate model, decline in outdoor activities (odds ratio [OR] 17.2, 95% confidence interval [CI] 9.15-32.2, p <0.001) and history of COVID-19 infection (OR 2.22, 95% CI 1.28-3.84, p = 0.004) were associated with depression. Additionally, we found that age ≥ 75 years, female sex, being underweight, limitations in functional status, poor sleep quality, and stroke were associated with depression. Of the associated factors, decline in outdoor activities had a moderate strength of association with depression (r = 0.419), while each of the remaining factors had a weak strength of association. CONCLUSIONS: COVID-19 had a direct and indirect impact on depression in older adults, reflecting an association between both a history of COVID-19 infection and a decline in outdoor activities during the COVID-19 pandemic and depression in the older population.

Characterization of Regional Morphological Changes in Sagittal Craniosynostosis Following Endoscopic Strip Craniectomy With Post-operative Helmeting: Predictors for Success.

BACKGROUND: Sagittal craniosynostosis (SC) restricts craniofacial growth perpendicular to the sagittal plane resulting in scaphocephaly. The cranium grows in the anterior-posterior dimension causing disproportionate changes, which can be corrected with either cranial vault reconstruction (CVR) or endoscopic strip craniectomy (ESC) combined with post-operative helmet therapy. ESC is performed at an earlier age, and studies demonstrate benefits in risk profile and morbidity compared to CVR, with comparable results if the post-operative banding protocol is strictly upheld. We aim to identify predictors of successful outcome and, using three-dimensional (3D) imaging, assess cranial changes following ESC with post-banding therapy. MATERIALS AND METHODS: A single institution retrospective review was performed from 2015-19 for patients with SC who underwent ESC. Patients received immediate post-operative 3D photogrammetry for helmet therapy planning and implementation as well as post-therapy 3D imaging. Using these 3D images, the cephalic index (CI) for study patients was calculated before and after helmet therapy. In addition, Deformetrica™ was used to measure volume and shape changes of pre-defined anatomic skull regions (frontal, parietal, temporal, & occipital) based on the pre- and post-therapy 3D imaging results. Fourteen institutional raters evaluated the pre- and post-therapy 3D imaging in order to determine the success of the helmeting therapy. RESULTS: Twenty-one SC patients met our inclusion criteria. Using 3D photogrammetry, 14 raters at our institution rated 16 of the 21 patients to have had successful helmet therapy. There was a significant difference in CI following helmet therapy with both groups, but there was no significant difference in CI between the "successful" and "unsuccessful" groups. Furthermore, the comparative analysis demonstrated that the parietal region had a significantly higher change in mean RMS distance when compared to the frontal or occipital regions. CONCLUSION: For patients with SC, 3D photogrammetry may be able to objectively recognize nuanced findings not readily detectable when using CI alone. The greatest changes in volume were observed in the parietal region, which falls in line with treatment goals for SC. Patients deemed to have unsuccessful outcomes were found to be older at time of surgery and initiation of helmet therapy. This suggests that early diagnosis and management for SC may increase the likelihood of success.

Do investors' personalities predict market winners? Experimental setting and machine learning analysis.

This study uses experiments and surveys from 146 participants who participated in equity trading to explore the predictive power of the Big-five personality traits, social behaviours, along with self-attribution and demographic characteristics on trading performance. Interestingly, we found that investors who are more open and neurotic gain higher returns compared to the market benchmark. We also found that other social traits are associated with the effectiveness of stock trading, such as awareness of social and ethical virtues (fairness and politeness). Moreover, instead of using separate characteristics, this study employs machine learning to cluster these personal features to understand the interconnection between socioeconomic determinants and financial decisions. This study contributes new evidence to the existing literature that personalities could explain trading performance.

Isolation, characterization, and complete genome sequence of vibrio phage KIT04, a novel lytic phage of the subfamily ermolyevavirinae.

Vibrio phage KIT04 was isolated from muscle tissue samples collected from a local market in Vietnam. KIT04 is a lytic phage that is specific to Vibrio parahaemolyticus. The one-step growth curve determined the burst size and latent period of 0.01 multiplicity of infection KIT04 in V. parahaemolyticus as approximately 156 plaque-forming units/bacterium and 45 min, respectively. Vibrio phage KIT04 has an approximately 76.4 ± 4.5 nm diameter icosahedral head and a tail length of approximately 159.5 ± 16.6 nm long tail. KIT04 significantly reduced V. parahaemolyticus ATCC 17802 in vitro. Complete genome analysis showed that KIT04 had a 114,933 bp dsDNA genome with 40.24% G + C content and 160 open reading frames (ORFs). However, the phage genome contained 24 tRNAs and no lysogeny-related genes. Moreover, five of the 160 ORFs encoded unique hypothetical proteins, indicating that KIT04 is a novel phage. Genomic comparison indicated that KIT04 is closely related to the Vibrio phages pVp-1 and VPT02. Further, phylogenetic analysis of the major tail proteins and whole genome supported the KIT04 classification into the subfamily Ermolyevavirinae. Our study describes a new candidate phage that could be used as a bioagent for controlling Vibrio pathogens.

Area Deprivation Index is Associated with Variation in Quality of Life and Psychosocial Well-being Following Breast Cancer Surgery.

BACKGROUND: Neighborhood-level factors have been shown to influence surgical outcomes through material deprivation, psychosocial mechanisms, health behaviors, and access to resources. To date, no study has examined the relationship between area-level deprivation (ADI) and post-mastectomy outcomes. METHODS: A cross-sectional survey of adult female breast cancer patients who underwent lumpectomy or mastectomy between January 2018 to June 2019 was carried out. Patient-specific characteristics and ADI information were abstracted and correlated with postoperative global- (SF-12) and condition-specific (BREAST-Q) quality-of-life performance via multivariable regression. Patients were classified into three ADI terciles: 0-39 (low deprivation), 40-59 (moderate deprivation), and 60-100 (high deprivation). RESULTS: A total of 564 consecutive patients were identified, being mostly white (75%) with mean age of 60.2 ± 12.4 years, median body mass index of 27.8 [interquartile range (IQR) 24.3-32.2) kg/m2, median Charlson Comorbidity Index of 3 (IQR 2-5), and mean ADI of 42.3 ± 25.7. African American and Hispanic patients and those with high BMI were more likely to reside in highly deprived neighborhoods (p = 0.003 and p < 0.001). In adjusted models, patients in highly deprived neighborhoods had significantly lower mean SF-12 physical (44.9 [95% CI, 43.8-46.0] versus 44.9 [95% CI, 43.7-46.1] versus 46.3 [95% CI, 45.3-47.3], p = 0.03) and BREAST-Q psychosocial well-being scores (63.5 [95% CI, 59.32-67.8] versus 69.3 [95% CI, 65.1-73.6] versus 69.7 [95% CI, 66.4-73.1], p = 0.01) relative to moderate- and low-deprivation groups. CONCLUSIONS: Patients residing in the most deprived neighborhoods were identified to have worse psychological well-being and quality-of-life. The ADI should be incorporated into the shared decision-making process and perioperative counseling to engender value-based and personalized care, especially for vulnerable populations.
